7 Minor textprop integer cleanup.
8 * intervals.h, textprop.c (add_text_properties_from_list):
9 Return void, not int, since nobody uses the return value.
10 * textprop.c (validate_plist, add_properties, remove_properties)
11 (Fadd_text_properties):
12 Don't assume list length fits in int.
13 (interval_has_all_properties, interval_has_some_properties)
14 (interval_has_some_properties_list, add_properties, remove_properties)
15 (Fadd_text_properties, Fremove_text_properties)

22 2013-02-25 Eli Zaretskii <eliz@gnu.org>
24 Implement CLASH_DETECTION for MS-Windows.
26 * filelock.c [WINDOWSNT]: Include w32.h.
27 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
28 function of that name. Up-case the macro arguments.
29 (IS_LOCK_FILE): New macro.
30 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
31 (create_lock_file): New function, with body extracted from
33 [WINDOWSNT]: Implement lock files by writing a regular file with
34 the lock information as its contents.
35 (read_lock_data): New function, on Posix platforms just calls
37 [WINDOWSNT]: Read the lock info from the file.
38 (current_lock_owner): Call read_lock_data instead of calling
39 emacs_readlinkat directly.
40 (lock_file) [WINDOWSNT]: Run the file name through
43 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
44 just check if the process by that PID exists.
46 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
47 also present, as doing so will fail to error out if the file
50 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
52 * textprop.c (Fadd_text_properties, Fremove_text_properties)
53 (Fremove_list_of_text_properties): Skip all of the intervals in
54 the region between START and END that already have resp. don't
55 have the requested properties, not just the first one. Add
56 assertions that the loop afterwards always modifies the
57 properties. (Bug#13743)
59 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
61 * callint.c (Fcall_interactively): Use the right lexical environment
62 for `interactive' specs (bug#13811).

65 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
67 Simplify data_start configuration (Bug#13783).
68 This is a followon simplification to the fix for Bug#13650.
69 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
70 (START_FILES): Remove. All uses removed.
71 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
72 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.

81 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
82 [__GNUC__ && !ORDINARY_LINK]: Remove.
83 * mem-limits.h, pre-crt0.c: Remove.
84 * unexaix.c, unexcoff.c: Don't include mem-limits.h.
85 * unexcoff.c (etext): New decl.
86 (make_hdr): Use DATA_START instead of start_of_data.
87 * vm-limit.c: Move most of mem-limits.h's contents here.
88 (data_start): New decl. It's OK if this is approximate,
89 so simplify-away some unnecessary exactness.
90 (POINTER): Remove; all uses removed.
91 (data_space_start): Now char *, to avoid casts.
92 (exceeds_lisp_ptr): New function, replacing the old
93 EXCEEDS_LISP_PTR macro. All uses changed.
94 (check_memory_limits): Simplify and remove casts.
95 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

103 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
105 Fix regression introduced by July 10 filelock.c patch.
106 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
107 2012-07-10 patch to this file. Reported by Eli Zaretskii in
108 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
109 and diagnosed by Andreas Schwab in
110 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
112 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
114 Assume C89 or better.
115 * ralloc.c (SIZE, POINTER, NIL):
116 * vm-limit.c (POINTER):
117 Remove, replacing all uses with C89 equivalents. These old
118 symbols were present only for porting to pre-C89 platforms.
120 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
122 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
123 This avoids warning messages reported as part of Bug#13546.
125 2013-02-21 Ken Brown <kbrown@cornell.edu>
127 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
129 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
131 * sheap.c (report_sheap_usage): Prefer message1_nolog.
133 * keyboard.c (Qcommand_execute): New var.
134 (command_loop_1, read_char): Use it.
135 (Fcommand_execute): Remove, replace by an Elisp implementation.
136 (syms_of_keyboard): Adjust accordingly.
138 2013-02-19 Daniel Colascione <dancol@dancol.org>
140 * sheap.c (report_sheap_usage): Use message, not message1, so
141 that we don't try to create a buffer while we're in the middle
142 of dumping Emacs. Explain why.
144 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
145 * search.c (find_newline): Return byte position in bytepos.
147 (find_next_newline_no_quit, find_before_next_newline):
148 Add bytepos argument.

155 (get_visually_first_element, move_it_vertically_backward):
156 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
158 2013-02-19 Eli Zaretskii <eliz@gnu.org>
160 * w32proc.c (new_child): Avoid leaking handles if the subprocess
161 resources were not orderly released.
163 2013-02-17 Eli Zaretskii <eliz@gnu.org>
165 * xdisp.c (x_draw_vertical_border): For a window that is neither
166 the leftmost nor the rightmost, redraw both the left and the right
167 vertical borders. (Bug#13723)
169 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
171 * xml.c (init_libxml2_functions):
172 * sound.c (sound_warning):
173 * sheap.c (report_sheap_usage):
174 * process.c (wait_reading_process_output):

178 * editfns.c (Fmessage, Fmessage_box):
179 * callint.c (Fcall_interactively):
180 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
182 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
184 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
185 * frame.c (syms_of_frame): ... to here.

189 * w32.c (sys_chown): Remove unused function.
191 * w32term.c <input_signal_count>: Declare 'volatile'
192 unconditionally. (Bug#9066)
194 * w32.c (set_errno): Reset h_errno and don't set it to any other
195 value. Set errno instead.
196 (check_errno): Reset h_errno.
197 (sys_socket, socket_to_fd, sys_bind, sys_connect)
198 (sys_gethostname, sys_getservbyname, sys_getpeername)
199 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
200 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
202 (sys_gethostbyname): Set h_errno only errors detected.
204 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
206 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
208 2013-02-15 Eli Zaretskii <eliz@gnu.org>
210 * keyboard.c (read_char): Fix calculation of auto-save time out
211 when auto-save-timeout is less than 4. (Bug#13720)
213 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

219 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
220 make sure errno is set to an appropriate value. (Bug#13546)
221 (socket_to_fd): Add assertion against indexing fd_info[] with a
222 value that is out of bounds.
223 (sys_accept): If fd is negative, do not set up the child_process
224 structure for reading.
226 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>

236 (decode_mode_spec_coding, message3):
237 * xfaces.c (face_at_string_position): Use bool for booleans.
240 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
242 Fix AIX port (Bug#13650).
243 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
244 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
245 was #undeffed earlier, so it cannot be used as a macro here.
246 Use the constant and not the macro.
248 2013-02-15 Eli Zaretskii <eliz@gnu.org>
250 * w32proc.c (new_child): If no vacant slots are found in
251 child_procs[], make another pass looking for slots whose process
252 has exited or died. (Bug#13546)
254 * w32.c (sys_pipe): When failing due to file descriptors above
255 MAXDESC, set errno to EMFILE.
256 (_sys_read_ahead): Update cp->status when failing to read serial
257 communications input, so that the status doesn't stay at
258 STATUS_READ_IN_PROGRESS. (Bug#13546)
260 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
262 * gtkutil.c (tb_size_cb): New function.
263 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
265 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
267 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
270 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
272 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
274 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
276 * font.c (font_range): Add pos_byte argument. Adjust comment
278 * font.h (font_range): Adjust prototype.
279 * composite.c (autocmp_chars): Pass byte position to font_range.
280 Break long line. Remove useless prototype and format comment.
282 2013-02-13 Glenn Morris <rgm@gnu.org>
284 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
286 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
288 Improve AIX port some more (Bug#13650).
289 With this, it should be as good as it was in 23.3, though it's
290 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
291 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
292 * unexaix.c (start_of_text): Remove.
293 (_data, _text): Declare as char[], not int, as AIX manual suggests.
294 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
295 (orig_load_scnptr, orig_data_scnptr):
296 Now off_t, not long, since they are file offsets.
297 (make_hdr): Use _data, not start_of_data ().
298 This is the key part of the fix.
299 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
300 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
302 * pre-crt0.c (data_start): Initialize to 1.
303 This ports to compilers that optimize the external declaration
304 'int x = 0;' as if it were 'int x;' to shrink the executable.
306 Improve AIX port (Bug#13650).
307 This doesn't fix the bug, but it makes progress: Emacs builds now.
308 * unexaix.c: Include inttypes.h, stdarg.h.
309 (report_error, report_error_1): Mark as _Noreturn.
310 (report_error): Don't report the wrong errno.
311 (report_error_1): Now varargs. All callers changed.
312 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
313 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
314 (write_ptr): Use %p to print address rather than %lx and a cast
315 to unsigned long. Grow buffer a bit, to be safer.
317 2013-02-13 Eli Zaretskii <eliz@gnu.org>
319 * bidi.c (bidi_resolve_neutral): After finding the next
320 non-neutral character, accept NEUTRAL_ON type as well, because
321 directional control characters, such as LRE and RLE, have their
322 type converted to that by bidi_resolve_weak. This avoids aborts
323 when LRE/RLE follows a run of neutrals.
324 (bidi_move_to_visually_next): Assert that return value of
325 bidi_peek_at_next_level is non-negative. Negative values will
328 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
330 Minor getenv-related fixes.
331 * callproc.c (Fcall_process_region) [!DOS_NT]:
332 Avoid unnecessary duplicate call to getenv.
333 * callproc.c (init_callproc):
334 * dispnew.c (init_display):
335 * sysdep.c (sys_subshell):
336 Omit unnecessary cast of getenv or egetenv.
338 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
340 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
343 2013-02-12 Eli Zaretskii <eliz@gnu.org>
345 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
347 (display_line): Set w->region_showing to the value of
348 it->region_beg_charpos, not to -1. This fixes redisplay
349 optimization when cursor is moved up after M->. (Bug#13623)
351 (try_scrolling): Scroll text up more if point is too close to ZV
352 and inside the scroll margin. This makes sure point is moved
353 outside the scroll margin in these cases.
355 * window.h (struct window): region_showing can no longer be
358 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
360 Tune by using memchr and memrchr.
361 * doc.c (Fsnarf_documentation):
362 * fileio.c (Fsubstitute_in_file_name):
363 * search.c (find_newline, scan_newline):
364 * xdisp.c (pos_visible_p, display_count_lines):
365 Use memchr and memrchr rather than scanning byte-by-byte.
366 * search.c (find_newline): Rename from scan_buffer.
367 Omit first arg TARGET, as it's always '\n'. All callers changed.
369 Clean up read_key_sequence a tiny bit more.
370 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
371 (read_key_sequence): Remove unused locals.
373 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
375 Clean up read_key_sequence a bit; reread active keymaps after first event.
376 * keyboard.c (read_char, read_char_x_menu_prompt)
377 (read_char_minibuf_menu_prompt):
378 Replace nmaps+maps with a single `map' arg.
379 (follow_key): Operate on a single map.
380 (active_maps): New function.
381 (test_undefined): Also return true for nil bindings.
382 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
383 a single (composed) keymap. Remember `first_event' to choose the right
384 set of active keymaps. Recompute the set of keymaps after receiving
385 the first event. Remove GOBBLE_FIRST_EVENT.
386 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
387 * keyboard.h (read_char): Update declaration.
388 * lread.c (read_filtered_event): Adjust call to read_char.
390 2013-02-11 Eli Zaretskii <eliz@gnu.org>
392 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
393 Don't use the limitation on backwards movement when lines are truncated
394 in the window. (Bug#13675)
396 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
398 * marker.c (set_marker_internal): If desired position is passed
399 as a marker, avoid call to buf_charpos_to_bytepos.
400 * window.c (Fset_window_point): Omit redundant type checking.
401 (Fset_window_start): Likewise. Format comment.
402 (window_scroll_pixel_based): Use set_marker_restricted_both
403 with character and byte positions obtained from an iterator.
404 (Fset_window_configuration): Use set_marker_restricted_both.
405 * xdisp.c (message_dolog): Likewise.
407 2013-02-10 Eli Zaretskii <eliz@gnu.org>
409 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
410 When text lines are longer than window's screen lines, don't move back
411 too far. This speeds up some redisplay operations. (Bug#13675)
413 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
415 * syntax.c (scan_sexps_forward): Fix byte position calculation
416 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
418 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
420 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
423 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
425 Minor hashing refactoring.
426 * fns.c (SXHASH_REDUCE): Move to lisp.h.
427 (sxhash_float): Return EMACS_UINT, for consistency with the other
429 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
430 non-static inline function and therefore can't use static vars.
431 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
432 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
433 with the other hash functions.
435 2013-02-09 Eli Zaretskii <eliz@gnu.org>
437 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
438 XXXXXX part of the temporary file pattern is not downcased even
439 when w32-downcase-file-names is non-nil. (Bug#13661)
441 * xdisp.c (decode_mode_spec): Remove handling of %t.
443 * msdos.c (careadlinkatcwd): Remove.
445 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
447 * lread.c (skip_dyn_bytes): New function (bug#12598).

449 (load_each_byte): Remove. Update users.
451 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
453 * search.c (scan_buffer): Calculate end byte position just once.

480 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
482 * coding.c (Fdefine_coding_system_internal): Use AREF where
483 argument is known to be a vector.
484 * fns.c (Flocale_info): Likewise for ASET.
485 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
486 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
488 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
490 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
493 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
494 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
495 updateCollectionBehaviour.
497 * nsterm.m (NEW_STYLE_FS): Remove.
498 (ns_last_use_native_fullscreen): New variable.
499 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
500 (x_set_window_size): Do not take title bar and tool bar into account
501 if isFullscreen returns YES.
502 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
503 (check_native_fs): New function.
504 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
505 (ns_term_init): Remove NEW_STYLE_FS.
506 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
507 and tool bar if isFullscreen returns NO.
508 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
509 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
511 (window:willUseFullScreenPresentationOptions:): New method.
512 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
513 Hide toolbar if not enabled (Bug#13444).
514 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
515 Restore tool bar if enabled, hide it otherwise (Bug#13444).
516 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
517 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
518 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
519 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
520 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
521 (syms_of_nsterm): Add ns-use-native-fullscreen.
523 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
525 * fileio.c (Qchoose_write_coding_system): Now static.
527 2013-02-04 Eli Zaretskii <eliz@gnu.org>
529 * xdisp.c (window_buffer_changed): region_showing can be negative,
530 which still means region is being displayed.
531 (redisplay_internal): Resurrect code that forced redisplay of the
532 whole window when showing region and the mark has changed.
533 Record the new mark position to allow redisplay optimizations.
534 (display_line): If it->region_beg_charpos is non-zero, set the
535 window's region_showing member to -1. (Bug#13623) (Bug#13626)
537 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
538 not bitfield of 1 bit.
540 2013-02-03 Daniel Colascione <dancol@dancol.org>
542 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
543 daemon mode works on cygw32 when Emacs is installed and not just
546 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
548 Avoid file time stamp bug on MS-Windows (Bug#13149).
549 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
550 as FAT32 doesn't update time stamps when truncating them.
551 Also, check that a file time stamp is not a multiple of 100 ns;
552 this should catch all instances of the problem on MS-Windows,
553 as its native file system resolution is 100 ns or worse, and
554 checking for a non-multiple of 100 ns should impose only a small
555 overhead on systems with ns resolution.
557 2013-02-02 Eli Zaretskii <eliz@gnu.org>
559 Avoid encoding file names on MS-Windows when they need to be run
560 through dostounix_filename.
561 * w32.c (normalize_filename): Accept an additional argument
562 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
563 downcase it even if w32-downcase-file-names is non-nil.
564 (dostounix_filename): Accept an additional argument MULTIBYTE and
565 pass it to normalize_filename.
566 (emacs_root_dir): Adjust.
568 * msdos.h (dostounix_filename): Adjust prototype.
570 * w32.h (dostounix_filename): Adjust prototype.
572 * msdos.c (dostounix_filename): Accept an additional argument and
574 (init_environment): Adjust callers of dostounix_filename.
576 * fileio.c (Ffile_name_directory, file_name_as_directory)
577 (directory_file_name, Fexpand_file_name)
578 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
580 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
582 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
583 variables, as egetenv is case-insensitive for DOS_NT.
585 * dired.c (file_name_completion): Don't call Fdirectory_file_name
586 with an encoded file name.
588 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
589 Adjust calls to dostounix_filename.
591 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
593 * unexw32.c (unexec): Adjust call to dostounix_filename.
595 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
597 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
600 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
603 * callproc.c (Fcall_process): Make sure program name in PATH and
604 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
605 is passed to exec/spawnve, which fails unless the file-name
608 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
609 even if w32-quote-process-args is nil.
611 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
613 Fix timestamp bug when write-region appends nothing (Bug#13149).
614 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
615 the file's time stamp doesn't change if Emacs happens to write nothing
616 to the file, and on a buggy file system this could cause Emacs to
617 incorrectly infer that the file system doesn't have the bug.
618 Avoid this problem by inhibiting the inference in this case.
620 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
622 * window.h (struct window): Convert base_line_number, base_line_pos
623 and column_number_displayed members from Lisp_Object to ptrdiff_t.
624 Convert region_showing member from Lisp_Object to bitfield.
625 Remove sequence_number member. Adjust comments.
626 * window.c (sequence_number): Remove.
627 (make_window): Initialize column_number_displayed.
628 * print.c (print_object): Follow the printed representation of
629 frames and print window pointer to distinguish between windows.
630 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
631 * xdisp.c (wset_base_line_number, wset_base_line_pos)
632 (wset_column_number_displayed, wset_region_showing): Remove.
633 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
634 (try_scrolling, try_cursor_movement, redisplay_window)
635 (try_window_reusing_current_matrix, try_window_id, display_line)
636 (display_mode_lines, decode_mode_spec): Adjust users.
637 * .gdbinit (pwinx): Do not print sequence_number.
639 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
641 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
642 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
643 * dired.c: Include <fcntl.h>.
644 (open_directory): New function, which uses open and fdopendir
645 rather than opendir. DOS_NT platforms still use opendir, though.
646 (directory_files_internal, file_name_completion): Use it.
647 (file_attributes): New function, with most of the old Ffile_attributes.
648 (directory_files_internal, Ffile_attributes): Use it.
649 (file_attributes, file_name_completion_stat): First arg is now fd,
650 not dir name. All uses changed. Use fstatat rather than lstat +
652 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
653 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
654 (emacs_readlinkat): New function, with much of the old
655 Ffile_symlink_p, but with an fd argument for speed.
656 It uses readlinkat rather than careadlinkatcwd, so that it
657 need not assume the working directory.
658 (Ffile_symlink_p): Use it.
659 * filelock.c (current_lock_owner): Use emacs_readlinkat
660 rather than emacs_readlink.
661 * lisp.h (emacs_readlinkat): New decl.
662 (READLINK_BUFSIZE, emacs_readlink): Remove.
663 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
664 (emacs_norealloc_allocator, emacs_readlink): Remove.
665 This stuff is moved to fileio.c.
666 * w32.c (fstatat, readlinkat): New functions.
667 (careadlinkat): Don't check that fd == AT_FDCWD.
668 (careadlinkatcwd): Remove; no longer needed.
670 2013-01-31 Glenn Morris <rgm@gnu.org>
672 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
673 (Fwrite_region): Update for new choose_write_coding_system args.
674 Move the last piece of choose_write_coding_system here. (Bug#13522)
675 (syms_of_fileio): Add choose-write-coding-system.
677 2013-01-30 Eli Zaretskii <eliz@gnu.org>
679 * w32.c (sys_open): Zero out the flags for the new file descriptor.
680 (sys_close): Zero out the flags for the file descriptor before
681 closing it. (Bug#13546)
683 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
684 (logon_network_drive, stat_worker, symlink, chase_symlinks):
685 Use CharNextExA and CharPrevExA to iterate over file names encoded in
688 * w32.c (w32_get_long_filename, init_environment, readlink):
689 Support file names encoded in DBCS codepages.
690 (readlink): Use the current file-name-coding-system, not the ANSI
691 codepage, to decode and handle targets of symlinks.
693 2013-01-28 Eli Zaretskii <eliz@gnu.org>
695 * w32.c (opendir): Now accepts a 'const char *'.
697 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
699 Remove obsolete redisplay code. See the discussion at
700 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
701 * dispnew.c (preemption_period, preemption_next_check): Remove.
702 (Vredisplay_preemption_period): Likewise.
703 (update_frame, update_single_window, update_window, update_frame_1):
704 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
705 used, following the 2012-06-22 change.
707 2013-01-25 Eli Zaretskii <eliz@gnu.org>
709 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
711 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
713 * font.c (num_fonts): Remove the leftover from old
714 debugging code. Adjust comment style here and there.
715 * insdel.c (insert_1): Remove.
716 * lisp.h (insert_1): Remove prototype.
717 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
719 2013-01-25 Eli Zaretskii <eliz@gnu.org>
721 * w32.c (max_filename_mbslen): New function.
722 (normalize_filename, readdir): Use it to detect locales where ANSI
723 encoding of file names uses a double-byte character set (DBCS).
724 If a DBCS encoding is used, advance by characters using
725 CharNextExA, instead of incrementing a 'char *' pointer.
726 Use _mbslwr instead of _strlwr. (Bug#13515)
728 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
729 request of memory reservation to 1.7GB. (Bug#13065)
731 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
733 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
734 at check_extra_latin label. (Bug#13505)
736 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
738 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
739 Avoid redundant calls to strlen.
741 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
743 Drop async_visible and async_iconified fields of struct frame.
744 This is possible because async input is gone; for details, see
745 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
746 * frame.h (struct frame): Remove async_visible and async_iconified
747 members, convert garbaged to unsigned bitfield. Adjust comments.
748 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
749 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
750 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
751 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
752 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
754 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
755 properly. Likewise for obscured.
757 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
760 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
762 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
764 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
765 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
767 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
769 * xdisp.c (message2, message2_nolog): Remove functions.
770 (message3, message3_nolog): Extract nbytes and multibyteness directly
771 from the string. Change all callers.
772 (message3_nolog): Don't set message_enable_multibyte since set_message
773 will reset it anyway.
774 (message1, message1_nolog): Use message3.
775 (vmessage): Use a stack allocated buffer rather than f->message_buf.
776 (with_echo_area_buffer): Remove last two arguments. Update all callers.
777 (set_message): Drop all but the second arg, which has to be a string.
778 (set_message_1): Simplify now that we know that a1 is NULL and the
779 second arg is a string.
780 * frame.h (struct frame): Remove `message_buf' field.
781 Use glyphs_initialized_p instead.
782 (FRAME_MESSAGE_BUF): Remove macro.
783 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
784 * lisp.h (message2, message2_nolog): Remove declarations.
785 (message3, message3_nolog): Update declarations.
786 * keyboard.c (read_char_minibuf_menu_text)
787 (read_char_minibuf_menu_width): Remove vars.
788 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
789 to correctly handle multibyte strings.
790 * frame.c (delete_frame): Don't free message_buf any more.
791 * editfns.c (message_text, message_length): Remove vars.
792 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
793 * fileio.c (auto_save_error): Use message3 instead of message2.
794 * dispnew.c (adjust_frame_message_buffer): Remove function.
796 2013-01-23 Eli Zaretskii <eliz@gnu.org>
798 * w32term.c (w32fullscreen_hook): Account correctly for the screen
799 real estate used for the tool bar and the menu bar.
801 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
803 * insdel.c (prepare_to_modify_buffer): Force redisplay if
804 hidden buffer is prepared to modification (Bug#13164).
806 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
808 * window.h (struct window): Change window_end_valid member from
809 Lisp_Object to a bitfield. Adjust comments.
810 (wset_window_end_valid): Remove.
811 * window.c (adjust_window_count): Clear window_end_valid.
812 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
813 (Fwindow_line_height, set_window_buffer, Frecenter)
814 (Fsplit_window_internal, Fdelete_other_windows_internal)
815 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
816 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
817 * xdisp.c (check_window_end, reconsider_clip_changes)
818 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
819 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
820 (find_first_unchanged_at_end_row, try_window_id): Likewise.
822 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
824 * xdisp.c (mark_window_display_accurate): Simplify the loop
825 assuming that the only one of vchild, hchild or buffer window
826 slots is non-nil. Call mark_window_display_accurate_1 for
827 the leaf windows only.
828 (mark_window_display_accurate_1): Always assume leaf window.
831 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
833 * emacs.c (Qkill_emacs_hook): Now static.
835 * fileio.c (Finsert_file_contents): Simplify.
836 Remove unnecessary assignments and tests.
838 2013-01-21 Eli Zaretskii <eliz@gnu.org>
840 * w32.c (acl_set_file): Don't test for errors unless
841 set_file_security returns FALSE. Avoids spurious errors when
844 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
846 * fileio.c (Finsert_file_contents): Revert code introduced at
847 2013-01-18 in favor of the simpler and generally better fix.
848 Save stack space by removing 'buffer' and reusing 'read_buf'
851 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
853 * lisp.h (eabs): Define unconditionally (Bug#13419).
854 The old "#if !defined (eabs)" was an unnecessary revenant of back
855 when this macro was called "abs". Document 'eabs' better.
857 2013-01-19 Glenn Morris <rgm@gnu.org>
859 * fns.c (Frandom): Doc fix.
861 2013-01-19 Eli Zaretskii <eliz@gnu.org>
863 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
864 segfault when there are lots of overlays.
866 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
867 when there are lots of overlays.
868 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
869 for the details and a way to reproduce.
871 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
873 * fileio.c: Use O_APPEND to append.
874 This corresponds better to the natural interpretation of "append",
875 and avoids the need to open the output file twice, or to invoke
876 lseek when APPEND is neither nil nor a number.
877 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
878 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
879 file possibly twice, and lseeking to its end; this avoids the
880 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
881 at the same time: the combination is never needed and apparently
882 it doesn't work with DOS_NT.
884 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
885 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
887 Allow floating-point file offsets.
888 Problem reported by Vitalie Spinu in
889 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
890 * fileio.c (emacs_lseek): Remove.
891 (file_offset): New function.
892 (Finsert_file_contents, Fwrite_region): Use it.
894 2013-01-19 Chong Yidong <cyd@gnu.org>
896 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
897 aborting on Fsignal (Bug#13289).
899 2013-01-19 Eli Zaretskii <eliz@gnu.org>
901 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
902 set_file_security as failure due to insufficient privileges.
903 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
904 (fstat): Return owner and group like 'stat' and 'lstat' do.
906 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
908 Work around bug in CIFS and vboxsf file systems (Bug#13149).
909 The bug was observed on Ubuntu operating inside a virtual machine,
910 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
911 The workaround introduces a race condition on non-buggy hosts,
912 but it's an unlikely race and anyway there's a nearly identical
913 nearby race that can't be fixed.
914 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
916 (Fwrite_region): Test for file system time stamp bug.
917 (init_fileio): New function.
918 * lisp.h (init_fileio): Declare it.
919 * emacs.c (main): Call it.
921 * fileio.c (Finsert_file_contents): Simplify new diagnostic
922 and make it more consistent with other stat-failure diagnostics.
924 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
926 Fix crash when inserting data from non-regular files.
927 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
928 for the error description produced by valgrind.
929 * fileio.c (read_non_regular): Rename to read_contents.
930 Free Lisp_Save_Value object used to pass parameters.
931 (read_non_regular_quit): Rename to read_contents_quit.
932 (Finsert_file_contents): Redesign internal file reading loop to adjust
933 gap and end positions after each read and so help make_gap to work
934 properly. Do not signal an I/O error too early and so do not leave
935 not yet decoded characters in a buffer, which was the reason of
936 redisplay crash. Use list2 to build return value. Adjust comments.
938 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
940 Close a race when statting and reading files (Bug#13149).
941 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
942 This avoids a race if the file is renamed between stat and open.
943 This race is not the problem originally noted in Bug#13149;
944 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
946 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
948 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
949 objects, related functions and macros.
950 (make_save_value): Adjust prototype.

1278 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1280 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1281 (xg_update_menubar): Update title only if

1283 (xg_update_submenu): Skip tearoff only if
1284 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1285 (xg_initialize): Initialize xg_detached_menus only if
1286 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1288 * xterm.h (struct x_output): Surround handlebox_widget with
1289 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1290 toolbar_in_hbox is bool.
1292 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1294 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1295 (LIBS_GNUSTEP): Define.

1299 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1301 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or

1324 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1326 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1328 * fileio.c (file_name_as_directory, directory_file_name):
1329 Accept an additional argument MULTIBYTE to indicate whether the input C
1330 came from a multibyte or a unibyte Lisp string; all callers
1331 adjusted. Don't assume the input string is always multibyte.
1333 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1334 don't ENCODE_FILE them, and return a unibyte string if the input
1336 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1337 don't assume the input strings will always be multibyte. If the
1338 input strings are multibyte, decode strings obtained from C
1341 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1343 * lisp.h (toplevel): Add two notices to the comment about
1344 defining a new Lisp data type.

1348 * alloc.c (valid_lisp_object_p): Adjust comment.
1350 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1352 * keyboard.c (record_asynch_buffer_change): Initialize an event
1353 only if it's really needed.
1354 * frame.h (enum output_method): Remove output_mac member since
1355 it's a leftover from the deleted code.
1356 * frame.c (Fframep): Adjust user here ...
1357 * terminal.c (Fterminal_live_p): ... and here.
1358 * coding.c (Qmac): Now here because it's only used to denote
1359 end-of-line encoding type.
1360 (syms_of_coding): DEFSYM it.
1361 * frame.h (Qmac): Remove duplicated declaration.
1363 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1365 * window.c (select_window_1): Now static, since it's used only here.
1367 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1369 * window.c (window_body_cols): Subtract display margins from the
1370 window body width on TTYs as well. See
1371 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1372 for the original report.
1374 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1376 * xdisp.c (redisplay_window): Remove inner local variable
1377 because the outer shadowed one has the same meaning.
1378 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1380 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1381 (xg_create_tool_bar): Adjust users.
1383 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1385 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1386 * buffer.c (Fget_buffer_create): Use it to set compact field of
1387 struct buffer_text to avoid accessing an uninitialized value
1388 when compact_buffer is called for the first time.
1389 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1390 (Fset_buffer_modified_p): Use buffer_window_count to check
1391 whether the buffer is displayed in some window.

1396 * w32.c (acl_set_file): If setting the file security descriptor
1397 fails, and the new DACL is identical to the existing one, silently
1398 return success. This fixes problems for users backing up their
1399 own files without having the necessary privileges for setting
1400 security descriptors.
1402 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1404 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1405 after WaitForSingleObject returns normally. This expedites reader
1406 thread shutdown when delete_child triggers it.
1407 (reap_subprocess): More accurate commentary for why we call
1408 delete_child only when cp->fd is negative.
1410 * w32.c (sys_close): Do not call delete_child on a subprocess
1411 whose handle is not yet closed. Instead, set its file descriptor
1412 to a negative value, so that reap_subprocess will call
1413 delete_child on that subprocess when its SIGCHLD arrives.
1414 This avoids closing handles used for communications between sys_select
1415 and reader_thread, which doesn't give sys_select a chance to
1416 notice that the process exited and invoke the SIGCHLD handler for

1437 * fileio.c (Finsert_file_contents): Doc fix.
1439 * w32proc.c (new_child, delete_child, find_child_pid): For a
1440 subprocess, consider its slot being in use as long as its process
1441 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1442 slot when a new process is started immediately after killing
1443 another one, without waiting enough time for the first process to
1444 be reaped and resources allocated for it be orderly freed.
1446 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1448 2012-12-21 Chong Yidong <cyd@gnu.org>

1459 Remove now unused argument FNAME; all callers changed.
1460 (get_file_owner_and_group): Remove now unused argument FNAME; all
1463 2012-12-21 Chong Yidong <cyd@gnu.org>
1465 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1466 error for invalid chars, don't check for a nil return value.

1497 * textprop.c (set_text_properties_1): Do not allow NULL interval.

1503 * coding.c (Fdetect_coding_region): Do not check start and end with
1504 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1505 (code_convert_region): Likewise.

1509 * w32.c (acl_get_file, acl_set_file): Run the file name through

1526 * window.c (select_window_1): New func, extracted from select_window.
1527 (select_window): Use it.

1554 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1556 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1557 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1558 for some of that bug's symptoms can now cause Emacs to abort.
1559 Remove the workaround.
1560 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1561 The bug that caused SIGCHLD to get lost has been fixed, and the
1562 workaround for it can now cause Emacs to abort.
1564 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1566 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1606 * callproc.c (Fcall_process): Don't overwrite infile with result
1608 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1609 asynchronous subprocess, record the name of the input file name,
1611 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1612 delete the file, record it as pending deletion when the subprocess
1615 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1617 * editfns.c [HAVE_PWD_H]: Include grp.h.

1623 Fix permissions bugs with setgid directories etc. (Bug#13125)
1624 * dired.c (Ffile_attributes): Return t as the 9th attribute,

1635 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1637 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1638 try to get accurate owner and group information from NT file
1639 security APIs. This is to make most callers of 'stat' and
1640 'lstat', which don't need that information, much faster.
1642 * dired.c (Ffile_attributes) [WINDOWSNT]:
1643 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1644 owner and group information from 'lstat'.
1646 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1648 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1649 as that confuses set-auto-coding, so insist on the head-read

1675 files, fixing a regression from 24.2.
1676 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1678 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1680 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1681 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1682 Remove unnecessary S_ISLNK test, as (contra the comments) this
1683 function can't copy symlinks. Improve quality of error message
1684 when attempting to copy files that are neither regular files nor

1697 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1698 the dumped Emacs is not a sparse file, greatly improving Cygwin
1699 "make bootstrap" performance.

1703 * inotify.c (inotify_callback): Generate an Emacs event for every
1704 incoming inotify event.
1706 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1708 * xdisp.c (handle_face_prop): Fix logic of computing
1709 it->start_of_box_run_p.
1710 (append_space_for_newline): If the glyph row is R2L, reset the
1711 iterator's end_of_box_run_p flag before prepending the space glyph.
1712 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1713 iterator's start_of_box_run_p flag before prepending the stretch.

1715 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1716 left_box_line_p and right_box_line_p flags of the glyph for R2L
1717 glyph rows. (Bug#13011)

1909 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1911 * w32.c (unsetenv): Return 0 if the input string is too long.
1913 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1915 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1916 * alloc.c (xputenv): New function.
1917 * dbusbind.c (Fdbus_init_bus):
1919 * xterm.c (x_term_init):
1920 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1921 * editfns.c (initial_tz): Move static var decl up.
1922 (tzvalbuf_in_environ): New static var.
1923 (init_editfns): Initialize these two static vars.
1924 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1925 Save old TZ value on stack, if it's small.
1926 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1927 instead, use xputenv+unsetenv to set and restore TZ.
1928 (environbuf): Remove static var. All uses removed.
1929 (Fset_time_zone_rule): Do not save TZ and environ;
1930 no longer needed here.
1931 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1932 Move to inside set_time_zone_rule; they don't need file scope any more.
1933 (set_time_zone_rule): Maintain the TZ=value string separately.
1934 (syms_of_editfns): Don't initialize initial_tz;
1935 init_editfns now does it.
1936 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1937 * lisp.h (xputenv): New decl.
1939 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1941 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1943 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1945 * w32.c (unsetenv, sys_putenv): New functions.
1947 2012-12-08 Chong Yidong <cyd@gnu.org>
1949 * editfns.c (Finsert_char): Make the error message more
1950 informative (Bug#12992).
1952 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1954 Simplify get_lim_data.
1955 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1956 Remove USG and vlimit methods; no longer used these days.
1957 Add #error catchall just in case.
1959 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1960 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1961 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1962 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1963 (deleted_pid_list, Fdelete_process, create_process)
1964 (record_child_status_change, handle_child_signal, deliver_child_signal)
1965 (init_process_emacs, syms_of_process):
1966 Assume SIGCHLD is defined.
1967 (parse_signal): Remove. All uses removed.
1968 (abbr_to_signal): New static function.
1969 (Fsignal_process): Use it to convert signal names to ints.
1970 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1971 kill (getpgrp (), ...).
1972 (emacs_sigaction_init): Assume SIGCHLD is defined.
1973 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1974 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1975 * syssignal.h (EMACS_KILLPG): Remove.
1976 All uses replaced by 'kill' with a negative pid.
1977 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1978 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1980 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1982 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1983 This will cause a production Emacs to dump core instead of
1986 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1988 * frame.c (make_frame): Do not set window's buffer to t.
1989 * window.c (Fsplit_window_internal): Likewise. Previously it was
1990 used to indicate that the window is being set up. Now we use
1991 set_window_buffer for all new windows, so the condition in ...
1992 (Fset_window_buffer): ... is always true and can be removed.
1994 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1996 Convenient macro to check whether the buffer is hidden.
1997 * buffer.h (BUFFER_HIDDEN_P): New macro.
1998 * frame.c (make_frame): Use it. Adjust comment.
1999 * buffer.c (candidate_buffer): New function.
2000 (Fother_buffer, other_buffer_safely): Use it.
2002 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2004 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2005 if the child process is still running. Instead, exit the wait
2006 loop and return zero. (Bug#13086)
2008 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2010 * frame.h (x_char_width, x_char_height): Remove prototypes.
2011 * w32term.h (x_char_width, x_char_height): Likewise.
2012 * xfns.c (x_char_width, x_char_height): Remove.
2013 * w32fns.c (x_char_width, x_char_height): Likewise.
2014 * nsfns.c (x_char_width, x_char_height): Likewise.

2021 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2023 Fix a recently-introduced delete-process race condition.
2024 * callproc.c, process.h (record_kill_process):
2025 New function, containing part of the old call_process_kill.
2026 (call_process_kill): Use it.
2027 This does not change call_process_kill's behavior.
2028 * process.c (Fdelete_process): Use record_kill_process to fix a
2029 race condition that could cause Emacs to lose track of a child.
2031 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2033 Avoid code duplication between prev_frame and next_frame.
2034 * frame.c (candidate_frame): New function. Add comment.
2035 (prev_frame, next_frame): Use it. Adjust comment.
2037 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2039 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2040 fails, signal an error instead of continuing with an empty
2042 Encode expanded temp file pattern before passing it to mkstemp or
2045 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2046 Encode the file name before passing it to dostounix_filename, in
2047 case it will downcase it (under w32-downcase-file-names).
2050 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2052 Minor call-process cleanups.
2053 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2054 at the same time as other platforms, to simplify analysis.
2055 No need for fd0_volatile since we have synch_process_fd.
2056 Avoid needless emacs_close; arg is always negative.
2058 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2060 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2063 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2065 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2066 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2067 and mouse_face_hidden members to a bitfields.
2068 * frame.h (struct frame): Remove set-but-not-used space_width member.
2069 (FRAME_SPACE_WIDTH): Remove.
2070 * nsterm.m, w32term.c, xterm.c: Adjust users.
2071 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2072 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2073 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2074 members to a bitfields.
2076 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2078 Don't let call-process be a zombie factory (Bug#12980).
2079 Fixing this bug required some cleanup of the signal-handling code.
2080 As a side effect, this change also fixes a longstanding rare race
2081 condition whereby Emacs could mistakenly kill unrelated processes,
2082 and it fixes a bug where a second C-g does not kill a recalcitrant
2083 synchronous process in GNU/Linux and similar platforms.
2084 The patch should also fix the last vestiges of Bug#9488,
2085 a bug which has mostly been fixed on the trunk by other changes.
2086 * callproc.c, process.h (synch_process_alive, synch_process_death)
2087 (synch_process_termsig, sync_process_retcode):
2088 Remove. All uses removed, to simplify analysis and so that
2089 less consing is done inside critical sections.
2090 * callproc.c (call_process_exited): Remove. All uses replaced
2091 with !synch_process_pid.
2092 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2093 These take the role of what used to be in unwind-protect arg.
2095 (block_child_signal, unblock_child_signal):
2096 New functions, to avoid races that could kill innocent-victim processes.
2097 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2098 (call_process_kill): Record killed processes as deleted, so that
2099 zombies do not clutter up the system. Do this inside a critical
2100 section, to avoid a race that would allow the clutter.
2101 (call_process_cleanup): Fix code so that the second C-g works again
2102 on common platforms such as GNU/Linux.
2103 (Fcall_process): Create the child process in a critical section,
2104 to fix a race condition. If creating an asynchronous process,
2105 record it as deleted so that zombies do not clutter up the system.
2106 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2107 light of these changes. Omit unnecessary call to emacs_close
2108 before failure, as the unwind-protect code does that.
2109 * callproc.c (call_process_cleanup):
2110 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2111 * process.c (record_deleted_pid): New function, containing
2112 code refactored out of Fdelete_process.
2113 (Fdelete_process): Use it.
2114 (process_status_retrieved): Remove. All callers changed to use
2115 child_status_change.
2116 (record_child_status_change): Remove, folding its contents into ...
2117 (handle_child_signal): ... this signal handler. Now, this
2118 function is purely a handler for SIGCHLD, and is not called after
2119 a synchronous waitpid returns; the synchronous code is moved to
2120 wait_for_termination. There is no need to worry about reaping
2121 more than one child now.
2122 * sysdep.c (get_child_status, child_status_changed): New functions.
2123 (wait_for_termination): Now takes int * status and bool
2124 interruptible arguments, too. Do not record child status change;
2125 that's now the caller's responsibility. All callers changed.
2126 Reimplement in terms of get_child_status.
2127 (wait_for_termination_1, interruptible_wait_for_termination):
2128 Remove. All callers changed to use wait_for_termination.
2129 * syswait.h: Include <stdbool.h>, for bool.
2130 (record_child_status_change, interruptible_wait_for_termination):
2132 (record_deleted_pid, child_status_changed): New decls.
2133 (wait_for_termination): Adjust to API changes noted above.
2135 * bytecode.c, lisp.h (Qbytecode): Remove.
2136 No longer needed after 2012-11-20 interactive-p changes.
2138 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2140 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2141 the scroll margin, move point outside the margin. (Bug#13055)
2143 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2145 * gtkutil.c (my_log_handler): New function.
2146 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2148 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2150 * lisp.h (modify_region): Rename to...
2151 (modify_region_1): ...new prototype.
2152 * textprop.c (modify_region): Now static. Adjust users.
2153 * insdel.c (modify_region): Rename to...
2154 (modify_region_1): ...new function to work with current buffer.
2155 Adjust comment and users. Use true and false for booleans.
2157 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2159 * alloc.c (free_save_value): New function.
2160 (safe_alloca_unwind): Use it.
2161 * lisp.h (free_save_value): New prototype.
2162 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2164 (save_excursion_restore): Adjust to match saved data structure.
2165 Use free_save_value to offload some work from GC. Drop obsolete
2168 2012-12-03 Chong Yidong <cyd@gnu.org>
2170 * fileio.c (Vauto_save_list_file_name): Doc fix.
2172 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2174 * w32fns.c: Remove prototype of atof.
2175 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2177 (file_dialog_callback): Make it UINT_PTR.
2179 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2182 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2183 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2186 2012-12-03 Glenn Morris <rgm@gnu.org>
2188 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2190 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2192 Fix xpalloc confusion after memory is exhausted.
2193 * alloc.c (xpalloc): Comment fix.
2194 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2195 and signals an error, do not clear charset_table_size, as
2196 charset_table is still valid.
2197 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2199 Use execve to avoid need to munge environ (Bug#13054).
2200 * callproc.c (Fcall_process):
2201 * process.c (create_process):
2202 Don't save and restore environ; no longer needed.
2203 * callproc.c (child_setup):
2204 Use execve, not execvp, to preserve environ.
2206 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2208 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2210 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2212 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2213 display for sliced images (Bug#10500).
2215 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2217 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2219 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2220 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2222 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2224 * xdisp.c (window_outdated): Remove eassert since it hits
2225 some suspicious corner cases (see Bug#13007 and Bug#13012).
2226 (mode_line_update_needed): New function.
2227 (redisplay_internal, redisplay_window): Use it.
2228 (ensure_selected_frame): New function.
2229 (redisplay_internal, unwind_redisplay): Use it.
2230 (redisplay_internal): Move comment about buffer_shared...
2231 (buffer_shared_and_changed): ...near to its real use.
2233 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2235 * callproc.c (Fcall_process): Don't misreport vfork failure.
2237 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2239 * callproc.c (Fcall_process): Fix vfork portability problems.
2240 Do not assume that fd[0], count, filefd, and save_environ survive
2241 vfork. Fix bug whereby wrong errno value could be reported for
2242 pipe failure. Some minor cleanups, too, as follows. Move buf and
2243 bufsize to the context where they're needed. Change new_argv to
2244 be of type char **, as this is more convenient and avoids casts.
2245 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2246 Now local constants, not macros.
2248 2012-11-18 Kenichi Handa <handa@gnu.org>
2250 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2251 for the variable "f".
2253 2012-11-13 Kenichi Handa <handa@gnu.org>
2255 * font.c (font_unparse_xlfd): Exclude special characters from the
2256 generating XLFD name.
2258 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2260 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2261 * dired.c (stat_uname, stat_gname):
2262 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2264 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2268 * fileio.c (Fcopy_file): Assume EISDIR is defined.
2269 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
2270 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
2271 * lread.c (readbyte_from_file): Assume EINTR is defined.
2272 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2273 Assume EIO and EAGAIN are defined.
2274 * unexcoff.c (write_segment): Assume EFAULT is defined.
2276 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2278 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2281 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2282 highlighting on the frame was cleared. Prevents assertion
2283 violations when repeatedly clicking on the "Top" link of the
2284 "bread-crumbs" in Info buffers.
2286 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2288 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2290 2012-11-24 Ken Brown <kbrown@cornell.edu>
2292 * keyboard.c (HAVE_MOUSE):
2293 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2294 were always defined.
2296 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2298 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2299 between bpos_covered and bpos_max. This fixes cursor display when
2300 several display strings follow each other.
2302 * .gdbinit (pgx): If the glyph's object is a string, display the
2303 pointer to string data, rather than the value of the string object
2304 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2306 * indent.c (Fvertical_motion): If the starting position is covered
2307 by a display string, return to one position before that, to avoid
2308 overshooting it inside move_it_to. (Bug#12930)
2310 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2312 * frame.h (struct frame): Remove display_preempted member
2313 since all users are dead long ago.

2315 * w32menu.c (pending_menu_activation): Remove since not
2317 (set_frame_menubar): Adjust user.
2318 * w32term.h (struct x_output): Drop outdated #if 0 code.
2319 (struct w32_output): Use bitfields for explicit_parent,
2320 asked_for_visible and menubar_active members.
2321 Drop unused pending_menu_activation member.
2322 * xterm.h (struct x_output): Drop outdated #if 0 code.
2323 Use bitfields for explicit_parent, asked_for_visible,
2324 has_been_visible and net_wm_state_hidden_seen members.
2326 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2328 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2329 of a literal "/". (Bug#12955)
2330 (gl-stamp): Invoke fc.exe directly, not through cmd.
2332 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2334 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2335 * dired.c: Assume HAVE_DIRENT_H.
2336 (NAMLEN): Remove, replacing with ...
2337 (dirent_namelen): New function. All uses changed. Use the GNU macro
2338 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2339 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2340 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2341 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2343 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2344 * ndir.h: Rename to ../nt/inc/dirent.h.
2345 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2346 Do not include <dirent.h>; no longer needed.
2347 * w32.c: Include <dirent.h> rather than "ndir.h".
2349 2012-11-23 Chong Yidong <cyd@gnu.org>
2351 * xftfont.c (xftfont_open): Remove duplicate assignment.
2353 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2355 * alloc.c (Fgarbage_collect): Unblock input after clearing
2356 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2357 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2358 * msdos.c (IT_frame_up_to_date): Use it here...
2359 * w32term.c (w32_frame_up_to_date): ...here...
2360 * xterm.c (XTframe_up_to_date): ...and here...
2361 * nsterm.m (ns_frame_up_to_date): ...but not here.
2362 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2364 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2365 Do not check whether GC is in progress.
2367 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2369 * xdisp.c (window_buffer_changed): New function.
2370 (update_menu_bar, update_tool_bar): Use it to
2371 simplify large 'if' statements.
2372 (redisplay_internal): Generalize commonly used
2373 'tail' and 'frame' local variables.
2375 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2377 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2378 with Windows system header.
2380 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2382 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2383 * alloc.c: Assume unistd.h exists.
2384 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2385 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2386 (getwd) [USG]: Remove; no longer needed.
2387 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2388 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2389 * w32.h (getcwd): Remove decl.
2391 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2393 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2394 Make it set selected_window as well.
2395 (update_tool_bar): Use it.
2397 2012-11-21 Ken Brown <kbrown@cornell.edu>
2399 * emacs.c (main): Set the G_SLICE environment variable for all
2400 Cygwin builds, not just GTK builds. See
2401 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2403 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2405 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2406 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2407 Define for the MSVC compiler.
2409 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2411 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2412 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2413 dostounix_filename. Prevents crashes down the road, because
2414 dostounix_filename assumes it gets a unibyte string.
2415 Reported by Michel de Ruiter <michel@sentient.nl>, see
2416 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2418 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2420 Conflate Qnil and Qunbound for `symbol-function'.

2422 * lread.c (init_obarray): Set `function' fields to Qnil.
2423 * eval.c (Fcommandp): Ignore Qunbound.
2424 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2425 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2426 Test NILP rather than Qunbound.
2427 (Ffmakunbound): Set to Qnil.
2428 (Fsymbol_function): Never signal an error.
2429 (Finteractive_form): Ignore Qunbound.
2431 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2433 * eval.c (interactive_p): Remove no-longer-used decl.
2435 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2437 * xdisp.c (buffer_shared): Adjust comment.
2438 (buffer_shared_and_changed): New function.
2439 (prepare_menu_bars, redisplay_internal): Use it to
2440 decide whether all windows or frames should be updated.
2441 (window_outdated): New function.
2442 (text_outside_line_unchanged_p, redisplay_window): Use it.
2443 (redisplay_internal): Likewise. Fix indentation.
2445 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2447 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2448 (syms_of_eval): Remove corresponding defsubr.
2449 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2451 2012-11-19 Daniel Colascione <dancol@dancol.org>
2453 * w32fns.c (Fx_file_dialog):
2454 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2455 cygwin_convert_file_name*.
2457 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2458 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2460 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2462 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2464 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2466 * w32select.c: Include w32common.h before w32term.h, so that
2467 windows.h gets included before w32term.h uses some of its
2468 features, see below.
2470 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2472 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2474 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2476 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2478 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2479 (ns_select): Return at once if events are held (Bug#12834).
2481 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2483 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2484 Needed following 2012-10-20 change. (Bug#12902)
2486 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2488 * w32proc.c (waitpid): Remove unused label get_result.
2490 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2492 * makefile.w32-in (SYSWAIT_H): New macro.
2493 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2494 ($(BLD)/sysdep.$(O)): Update dependencies.
2496 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2498 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2499 * callproc.c (relocate_fd): Assume F_DUPFD.
2500 * emacs.c, term.c (O_RDWR): Remove.
2501 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2502 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2503 * nsterm.m: Assume <fcntl.h> exists.
2504 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2505 (create_pty, Fmake_network_process, server_accept_connection)
2506 (wait_reading_process_output, init_process_emacs):
2508 (wait_reading_process_output): Put in a special case for WINDOWSNT
2509 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2510 It's not clear this is needed, but it's a more-conservative change.
2511 (create_process): Assume FD_CLOEXEC.
2512 (create_process, create_pty): Assume O_NOCTTY.
2513 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2514 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2515 Omit if not DOS_NT, since F_GETFL is not defined there.
2516 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2517 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2519 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2520 lack it, since gnulib guarantees this.
2521 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2523 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2525 * w32.c (faccessat): Pretend that directories have the execute bit
2526 set. Emacs expects that, e.g., in files.el:cd-absolute.
2528 * w32proc.c (create_child): Don't clip the PID of the child
2529 process to fit into an Emacs integer, as this is no longer a
2531 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2532 reaping only the process specified by PID argument, if that is
2533 positive. Use PID instead of dead_child to know which process to
2534 reap. Wait for the child to die only if WNOHANG is not in
2536 (sys_select): Don't set dead_child.
2538 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2539 as it is no longer needed.
2541 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2543 (record_child_status_change): Remove the setting of
2544 record_at_most_one_child for the !WNOHANG case.
2546 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2548 Fix problems in ns port found by static checking.
2549 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2550 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2551 not to process group.
2552 (ns_select): Use emacs_write, not write, as that's more robust
2553 in the presence of signals.
2554 (fd_handler:): Check for read errors.
2556 2012-11-16 Glenn Morris <rgm@gnu.org>
2558 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2560 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2562 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2564 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2566 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2567 use the same value of thread handle.
2568 (start_timer_thread): If the timer thread exited (due to error),
2569 clean up by closing the two handles it used. Duplicate the caller
2570 thread's handle here, so it gets duplicated only once, when
2571 launching the timer thread. Set priority of the timer thread, not
2573 (getitimer): Don't duplicate the caller thread's handle here.
2576 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2578 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2581 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2583 Remove no-longer-used pty_max_bytes variable.
2584 * process.c (pty_max_bytes): Remove; unused.
2585 (send_process): Do not set it.
2587 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2589 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2590 Update dependencies.
2592 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2594 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2595 This follows up on the 2012-09-29 patch that removed indirection
2596 for the 'function' field. Reported by Sergey Vinokurov in
2597 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2599 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2601 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2602 different name, as the MS runtime does not have such a function,
2603 and probably never will.) All callers changed. Ignore DIRFD
2604 value if PATH is an absolute file name, to match Posix spec
2605 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2608 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2610 * xdisp.c (echo_area_display, redisplay_internal):
2611 Omit redundant check whether frame_garbaged is set.
2613 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2615 Use faccessat, not access, when checking file permissions (Bug#12632).
2616 This fixes a bug that has been present in Emacs since its creation.
2617 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2618 which must set some sort of record. (Torek's bug report was against
2619 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2620 same common flaw.) See Torek's Usenet posting
2621 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2622 Posted: Fri Apr 8 14:18:56 1983.
2623 * Makefile.in (LIB_EACCESS): New macro.
2625 * callproc.c (init_callproc):
2626 * charset.c (init_charset):
2627 * fileio.c (check_existing, check_executable, check_writable)
2629 * lread.c (openp, load_path_check):
2630 * process.c (allocate_pty):
2632 Use effective UID when checking permissions, not real UID.
2633 * callproc.c (init_callproc):
2634 * charset.c (init_charset):
2635 * lread.c (load_path_check, init_lread):
2636 Test whether directories are accessible, not merely whether they exist.
2637 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2638 * fileio.c (check_existing, check_executable, check_writable)
2640 Use symbolic names instead of integers for the flags, as they're
2642 (check_writable): New arg AMODE. All uses changed.
2643 Set errno on failure.
2644 (Ffile_readable_p): Use faccessat, not stat + open + close.
2645 (Ffile_writable_p): No need to call check_existing + check_writable.
2646 Just call check_writable and then look at errno. This saves a syscall.
2647 dir should never be nil; replace an unnecessary runtime check
2648 with an eassert. When checking the parent directory of a nonexistent
2649 file, check that the directory is searchable as well as writable, as
2650 we can't create files in unsearchable directories.
2651 (file_directory_p): New function, which uses 'stat' on most platforms
2652 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2653 (Ffile_directory_p, Fset_file_times): Use it.
2654 (file_accessible_directory_p): New function, which uses a single
2655 syscall for efficiency.
2656 (Ffile_accessible_directory_p): Use it.
2657 * xrdb.c (file_p): Use file_directory_p.
2658 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2659 * lread.c (openp): When opening a file, use fstat rather than
2660 stat, as that avoids a permissions race. When not opening a file,
2661 use file_directory_p rather than stat.
2662 (dir_warning): First arg is now a usage string, not a format.
2663 Use errno. All uses changed.
2664 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2665 that merely introduced a race.
2666 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2667 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2668 and similarly for the other O_* flags.
2669 * w32.c (sys_faccessat): Rename from sys_access and switch to
2670 faccessat's API. All uses changed.
2671 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2672 (magic_db): Rename from magic_file_p.
2673 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2674 char *, so that we don't have to test for file existence
2675 separately from opening the file for reading. This removes a race
2676 fixes a permission-checking problem, and simplifies the code.
2678 (file_p): Remove; no longer needed.
2680 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2682 Omit glyphs initialization at startup.
2683 * dispnew.c (glyphs_initialized_initially_p): Remove.
2684 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2685 (Fredraw_frame): Move actual code from here...
2686 (redraw_frame): ...to here. Add eassert. Adjust comment.
2687 (Fredraw_display): Use redraw_frame.
2688 * xdisp.c (clear_garbaged_frames): Likewise.
2690 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2692 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2693 passed to pint2str and pint2hrstr to be at most the size of the
2694 frame's decode_mode_spec_buffer. This avoids crashes with very
2695 large values of FIELD_WIDTH argument to decode_mode_spec.
2698 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2700 Fix a race with verify-visited-file-modtime (Bug#12863).
2701 Since at least 1991 Emacs has ignored an mtime difference of no
2702 more than one second, but my guess is that this was to work around
2703 file system bugs that were fixed long ago. Since the race is
2704 causing problems now, let's remove that code.
2705 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2706 whose time stamp is off by no more than a second. Insist that the
2707 file time stamps match exactly.
2709 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2711 * frame.h (struct frame): Convert external_tool_bar member to
2712 1-bit unsigned bitfield.
2713 * termhooks.h (struct terminal): Remove mouse_moved member since
2714 all users are long dead. Adjust comment on mouse_position_hook.
2716 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2718 Simplify by using FOR_EACH_FRAME here and there.
2719 * frame.c (next_frame, prev_frame, other_visible_frames)
2720 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2721 * w32term.c (x_window_to_scroll_bar): Likewise.
2722 * window.c (window_list): Likewise.
2723 * xdisp.c (x_consider_frame_title): Likewise.
2724 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2725 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2726 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2727 * xmenu.c (menubar_id_to_frame): Likewise.
2728 * xselect.c (frame_for_x_selection): Likewise.
2729 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2730 (x_window_to_menu_bar): Likewise.
2731 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2733 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2735 * data.c (Qdefalias_fset_function): Now static.
2737 Another tweak to vectorlike_header change.
2738 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2739 Remove, and replace all uses with ...
2740 (next_in_free_list, set_next_in_free_list):
2741 New functions, which respect C's aliasing rules better.
2743 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2745 * window.c (list4i): Rename from 'quad'. All uses changed.
2746 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2748 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2750 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2751 warning about mixing declarations and code in ISO C90.
2753 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2755 * window.c (Fsplit_window_internal): Set combination limit of
2756 new parent window to t iff Vwindow_combination_limit is t;
2757 fixing a regression introduced with the change from 2012-09-22.
2758 (Fset_window_combination_limit): Fix doc-string.
2760 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2762 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2763 amount when the scroll margins are too large. When scrolling
2764 backwards in the buffer, give up if cannot reach point or the
2765 scroll margin within a reasonable number of screen lines.
2766 Fixes point position in window under scroll-up/down-aggressively when
2767 point is positioned many lines beyond the window top/bottom.
2770 * ralloc.c (relinquish): If real_morecore fails to return memory
2771 to the system, don't crash; instead, leave the last heap
2772 unchanged and return. (Bug#12774)
2774 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2776 * lisp.h (AUTOLOADP): New macro.
2777 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2778 * data.c (Ffset): Remove special ad-advice-info handling.
2779 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2781 (Finteractive_form): Simplify.
2782 (Fquo): Don't insist on having at least 2 arguments.
2783 (Qdefalias_fset_function): New var.
2785 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2787 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2789 * nsfont.m (Qcondensed, Qexpanded): New variables.
2790 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2791 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2793 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2795 Fix recently introduced crash on MS-Windows (Bug#12839).
2796 * w32term.h (struct scroll_bar): Use convenient header.
2797 (SCROLL_BAR_VEC_SIZE): Remove.
2798 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2800 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2802 Tweak last vectorlike_header change.
2803 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2804 vectorlike object on the free list. This is introduced to avoid

2811 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2813 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2839 special hash function containing a comparison that always yields 1.
2841 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2843 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2844 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2845 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2848 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2850 * image.c (xpm_make_color_table_h): Fix compiler error because
2851 make_hash_table changed.
2853 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2855 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2857 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2859 Use ad-hoc comparison function for the profiler's hash-tables.
2860 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2861 (make_log): Use them.

2872 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2873 (hash_lookup, hash_remove_from_table): Move assertion checking of
2874 hashfn result here. Check hash-equality before calling cmpfn.

2887 value of w32-scroll-lock-modifier is neither nil nor one of the
2888 known key modifiers. (Bug#12806)
2890 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2892 Shrink struct vectorlike_header to the only size field.
2893 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2895 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2896 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2897 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2898 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2899 information from the vector header. Adjust comment.

2922 Add easserts. Adjust XSETPVECTYPESIZE usage.
2923 (allocate_buffer): Use BUFFER_PVEC_INIT.
2924 (live_vector_p): Adjust to match large vector.
2925 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2926 * buffer.h (struct buffer): Add next member.

2937 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2939 * keyboard.c (event_to_kboard): Do not dereference
2940 frame_or_window field of SELECTION_REQUEST_EVENT
2941 and SELECTION_CLEAR_EVENT events (Bug#12814).
2942 * xterm.h (struct selection_input_event): Adjust comment.
2944 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2946 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2947 such as Scroll Lock, if the respective keys are treated as
2948 function keys, not as modifiers. This avoids destroying non-ASCII
2949 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2951 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2953 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2955 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2957 Restore some duplicate definitions (Bug#12814).
2958 This undoes part of the 2012-11-03 changes. Some people build
2959 with plain -g rather than with -g3, and they need the duplicate
2960 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2961 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2962 Define as macros, as well as as enums or as constants.
2964 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2966 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2967 to keypad keys (Bug#12816).
2969 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2971 Minor adjustments of recently-changed frame functions.
2972 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2973 known to be a frame (we're in the FRAMEP branch).
2974 * lisp.h (Qframep): Remove decl. frame.h declares this.
2975 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2976 since they're meant for Lisp fixnum values.
2978 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2980 * window.c (Fwindow_combination_limit): Revert to the only
2981 required argument and adjust docstring as suggested in
2982 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2983 by Martin Rudalics <rudalics@gmx.at>.
2985 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2987 Widely used frame validity and checking functions.
2988 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

3000 * lisp.h (frame_buffer_predicate): Remove prototype.
3001 * buffer.c (Fother_buffer): Use decode_any_frame.
3002 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3003 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3004 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3005 (Fclose_font, Ffont_info): Use decode_live_frame.
3006 * fontset.c (check_fontset_name): Likewise.
3007 * terminal.c (Fframe_terminal): Likewise.
3008 * w32fns.c (check_x_frame): Likewise.
3009 * window.c (Fminibuffer_window, Fwindow_at)
3010 (Fcurrent_window_configuration): Likewise.
3011 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3012 Likewise. Allow zero number of arguments. Adjust docstring.
3013 * dispnew.c (Fredraw_frame): Likewise.
3014 * xfaces.c (frame_or_selected_frame): Remove.
3015 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3016 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3017 (Fframe_face_alist): Use decode_live_frame.
3018 * xfns.c (check_x_frame): Likewise.
3020 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3022 * window.c (quad): New function.
3023 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3024 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3025 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3026 (Fwindow_line_height): Use it.
3027 (Fwindow_fringes): Use list3.
3028 (Fwindow_scroll_bars): Use list4.
3029 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3030 (Fwindow_combination_limit): Allow zero number of arguments.
3032 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3034 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3036 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3037 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3038 file descriptor 2 for standard error. (Bug#12805)
3040 2012-11-05 Chong Yidong <cyd@gnu.org>
3042 * process.c (wait_reading_process_output): Revert previous change.
3044 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3046 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3047 This removes code that has been obsolete since around 1990.
3048 * callproc.c (Fcall_process):
3050 * process.c (create_process):
3051 * term.c (dissociate_if_controlling_tty):
3052 Assume setsid exists.
3053 * callproc.c (child_setup): Assume setpgid exists and behaves as
3054 per POSIX.1-1988 or later.
3055 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3056 * emacs.c (shut_down_emacs):
3057 * sysdep.c (sys_suspend, init_foreground_group):
3058 Assume getpgrp behaves as per POSIX.1-1998 or later.
3059 * msdos.c (setpgrp): Remove.
3060 (tcgetpgrp, setpgid, setsid): New functions.
3061 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3062 * term.c (no_controlling_tty): Remove; unused.
3063 * w32proc.c (setpgrp): Remove.
3064 (setsid, tcgetpgrp): New functions.
3066 Simplify by assuming __fpending.
3067 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3068 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3069 Do not assume that __fpending's result fits in int.
3071 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3073 Remove EMACS_OUTQSIZE+sleep hack.
3074 * dispnew.c (update_frame_1): Remove hack for terminals slower
3075 than 2400 bps, which throttled Emacs by having it sleep.
3076 This code hasn't worked since at least 2007, when the multi-tty stuff
3077 was added, and anyway those old terminals are long dead.
3078 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3079 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3081 Fix data-loss with --version (Bug#9574).
3082 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3083 as we can't assume that emacs_strerror is initialized, and strerror
3084 is good enough here.
3085 (main): Invoke atexit earlier, to catch earlier instances of
3086 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3088 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3090 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3091 (keyDown): Remap keypad keys to X11 virtual key codes.
3093 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3095 Fix data-loss with --batch (Bug#9574).
3096 * emacs.c: Include <close-stream.h>.
3097 (close_output_streams): New function.
3098 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3099 and handles errors appropriately.
3100 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3103 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3104 The symptom is a diagnostic "GLib-WARNING **: In call to
3105 g_spawn_sync(), exit status of a child process was requested but
3106 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3107 waitpid(), so exit status can't be returned." The diagnostic
3108 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3109 The real bug is a race condition between Emacs and glib: Emacs
3110 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3111 so that glib can't find it. Work around the bug by invoking
3112 waitpid only on subprocesses that Emacs itself creates.
3113 * process.c (create_process, record_child_status_change):
3114 Don't use special value -1 in pid field, as the caller now must
3115 know the pid rather than having the callee infer it.
3116 The inference was sometimes incorrect anyway, due to another race.
3117 (create_process): Set new 'alive' member if child is created.
3118 (process_status_retrieved): New function.
3119 (record_child_status_change): Use it.
3120 Accept negative 1st argument, which means to wait for the
3121 processes that Emacs already knows about. Move special-case code
3122 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3123 processes that have already been waited for, by testing and
3124 clearing new 'alive' member.
3125 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3126 now does this internally.
3127 (handle_child_signal): Let record_child_status_change do all
3128 the work, since we do not want to reap all exited child processes,
3129 only the child processes that Emacs itself created.
3130 * process.h (Lisp_Process): New boolean member 'alive'.
3132 Omit duplicate definitions no longer needed with gcc -g3.
3133 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3134 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3135 Define only as macros. There's no longer any need to also define
3136 these symbols as enums or as constants, since we now assume
3137 gcc -g3 when debugging.
3139 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3141 * lisp.mk: Adjust comments to the fact that term/internal is now
3142 loaded from loadup.el.
3144 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3145 (msdos_fatal_signal): New function.
3146 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3149 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3150 for GCC versions before 4.
3151 (emacs_raise): Define to call msdos_fatal_signal.
3153 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3154 iterator when starting in the middle of a display or overlay
3157 2012-11-03 Chong Yidong <cyd@gnu.org>
3159 * process.c (wait_reading_process_output): Clean up the last
3162 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3164 * process.c (wait_reading_process_output): Avoid a race condition
3165 with SIGIO delivery (Bug#11536).
3167 2012-11-03 Chong Yidong <cyd@gnu.org>
3169 * buffer.c (cursor_type): Untabify docstring.
3171 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3173 * frame.h (struct frame): Drop can_have_scroll_bars member
3174 which is meaningless for a long time. Adjust comments.
3175 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3176 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3178 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3180 * window.c (decode_next_window_args): Update window arg after
3181 calling decode_live_window and so fix crash reported at
3182 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3183 by Juanma Barranquero <lekktu@gmail.com>.
3184 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3185 * font.c (Ffont_at): Likewise.
3187 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3189 * widget.c (resize_cb): New function.
3190 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3191 (EmacsFrameResize): Check if all is up to date before changing frame
3194 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3196 Implement backtrace output for fatal errors on MS-Windows.
3197 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3198 (BACKTRACE_LIMIT_MAX): New macro.
3199 (w32_backtrace): New function.
3200 (emacs_abort): Use w32_backtrace when the user chooses not to
3201 attach a debugger. Update the text of the abort dialog.
3203 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3205 Window-related stuff cleanup here and there.
3206 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3207 Use decode_any_window.
3208 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3209 * xdisp.c (Fformat_mode_line): Likewise.
3210 * font.c (Ffont_at): Use decode_live_window.
3211 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3212 * window.c (decode_next_window_args): Likewise.
3213 (decode_any_window): Remove static.
3214 * window.h (decode_any_window): Add prototype.
3215 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3216 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3219 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3221 Remove pad from struct input_event.
3222 * termhooks.h (struct input_event): Remove padding field.
3224 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3225 member is never cons for a long time. Adjust comment.
3226 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3227 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3228 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3229 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3231 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3233 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3235 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3237 Fix crash when using Emacs as commit editor for git (Bug#12697).
3238 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3239 and it is configured in conf_post.h.
3240 (Fcall_process): Don't invoke both setsid and setpgid; the former
3241 is enough, if it exists.
3242 * callproc.c (Fcall_process, child_setup):
3243 * process.c (create_process): Use setpgid.
3244 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3246 * dispnew.c (init_display): Initialize the foreground group
3247 if we are running a tty display.
3248 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3249 * lisp.h (init_foreground_group): New decl.
3250 * sysdep.c (inherited_pgroup): New static var.
3251 (init_foreground_group, tcsetpgrp_without_stopping)
3252 (narrow_foreground_group, widen_foreground_group): New functions.
3253 (init_sys_modes): Narrow foreground group.
3254 (reset_sys_modes): Widen foreground group.
3256 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3258 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3260 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3262 * minibuf.c (read_minibuf): Restore current buffer since
3263 choose_minibuf_frame calling Fset_frame_selected_window may
3264 change it (Bug#12766).
3266 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3268 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3270 2012-10-30 Kenichi Handa <handa@gnu.org>
3272 * font.c (Ffont_at): If WINDOW is specified and it is not
3273 displaying the current buffer, signal an error.
3275 2012-10-29 Daniel Colascione <dancol@dancol.org>
3277 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3278 In preparation for fixing bug#12739, move these functions from
3281 * coding.h, coding.c: ... to here, and compile them only when
3282 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3283 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3285 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3287 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3288 (timer_loop, getitimer, setitimer): Use it instead of
3289 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3291 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3294 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3296 * nsterm.m (NO_APPDEFINED_DATA): New define.

3298 (last_appdefined_event): Remove.
3299 (ns_select): Initialize t from last_appdefined_event_data instead
3300 of [last_appdefined_event data1].
3301 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3302 remove last_appdefined_event (Bug#12698).
3304 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3306 * frame.c (x_set_font): Catch internal error.
3308 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3310 Avoid overflow in w32 implementation of interval timers.
3311 When possible, for ITIMER_PROF count only times the main thread
3313 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3314 'volatile ULONGLONG' types. All the other data which was
3315 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3316 (GetThreadTimes_Proc): New typedef.
3317 (w32_get_timer_time): New function, returns a suitable time value
3319 (timer_loop): Enter critical section when accessing ULONGLONG
3320 values of the itimer_data struct, as these accesses are no longer
3321 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3322 Remove unused variable.
3323 (init_timers): Initialize s_pfn_Get_Thread_Times.
3324 (start_timer_thread): Don't assign itimer->caller_thread here.
3325 (getitimer): Assign itimer->caller_thread here.
3326 (setitimer): Always call getitimer to get the value of ticks_now.
3327 (sys_spawnve): Avoid compiler warning about format mismatch.
3329 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3331 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3332 mouse movement events if the menu bar is active. This avoids
3333 producing a busy "hour-glass" cursor by Windows if the mouse
3334 pointer is positioned over a tooltip shown for some menu item.
3336 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3338 Don't assume process IDs fit in int.
3339 * emacs.c (shut_down_emacs) [!DOS_NT]:
3340 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3341 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3342 Use pid_t, not int, to store process IDs, as 'int'
3343 is not wide enough on a few platforms (e.g., AIX and IRIX).
3345 2012-10-23 Kenichi Handa <handa@gnu.org>
3347 The following change is to make face-font-rescale-alist work
3348 correctly for non-ASCII fonts.
3350 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3351 (font_open_for_lface): Handle Vface_font_rescale_alist.
3353 2012-10-23 Chong Yidong <cyd@gnu.org>
3355 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3357 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

3366 2012-10-21 Glenn Morris <rgm@gnu.org>
3368 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3370 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3372 Port to OpenBSD 5.1.
3373 * frame.c (Fmouse_position, Fmouse_pixel_position):
3374 * xdisp.c (produce_stretch_glyph):
3375 Declare local vars only when they're needed.
3376 This is clearer and avoids a warning on OpenBSD about unused vars.

3378 This is safer, and avoids OpenBSD warnings about unused vars.
3379 * keyboard.c (record_menu_key): Remove unnecessary decl.
3380 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3381 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3382 as our definition clashes with OpenBSD's.
3383 * xfaces.c (load_face_colors, check_lface_attrs)
3384 (get_lface_attributes_no_remap, get_lface_attributes)
3385 (lface_fully_specified_p, x_supports_face_attributes_p)
3386 (tty_supports_face_attributes_p, face_fontset, realize_face)
3387 (realize_x_face, realize_tty_face):
3388 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3389 merely Lisp_Object *. This is more informative and avoids
3390 a warning on OpenBSD about accessing beyond an object's size.
3392 2012-10-20 Chong Yidong <cyd@gnu.org>
3394 * lread.c (Fload): Doc fix (Bug#12592).

3420 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3421 (staticpro): If we run out of staticpro slots, die with an
3422 informative error instead of just calling emacs_abort.
3424 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3426 Fix two flaws reported by Dmitry Antipov.

3681 since unsigned is guaranteed to have that behavior and signed is not.

3683 (get_input_pending): Remove first argument, since it was always
3684 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3685 and behave as if it had that value. Return new value of
3686 input_pending. All callers changed.
3687 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3688 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3717 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3719 * commands.h (immediate_quit): Remove duplicate decl.
3721 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3723 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3726 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3728 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3730 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3731 match what GetLastError returns. Explain why the function is
3734 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3735 'is_tooltip_frame', to avoid confusion with its global namesake.
3737 2012-10-08 Daniel Colascione <dancol@dancol.org>
3739 * xdisp.c (start_hourglass): Call w32_note_current_window when
3740 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3741 build that caused Emacs to display the hourglass cursor forever.
3743 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3744 which is broken under remote desktop, calculate the number of
3745 colors available for a display based on the display's number of
3746 planes and number of bits per pixel per plane. (bug#10397).
3748 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3750 * nsfont.m (Vfonts_in_cache): New variable.
3751 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3752 are used. Add cached fonts to Vfonts_in_cache.
3753 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3755 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3757 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3759 (FONT_H): Define after FRAME_H.
3760 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3761 Update dependencies.
3763 * w32term.c: Remove leftover declaration of keyboard_codepage.
3765 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3767 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3768 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3769 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3770 (GLOBAL_SOURCES): Add cygw32.c.
3771 ($(BLD)/unexw32.$(O)):
3773 ($(BLD)/w32console.$(O)):
3774 ($(BLD)/w32fns.$(O)):
3775 ($(BLD)/w32heap.$(O)):
3776 ($(BLD)/w32menu.$(O)):
3777 ($(BLD)/w32proc.$(O)): Add w32common.h.
3779 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3781 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3783 2012-10-08 Daniel Colascione <dancol@dancol.org>
3785 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3786 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3787 accidental message numbering hole. Change other messages to
3790 * w32select.h (HAVE_W32SELECT): Remove.
3792 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3793 w32common.h instead of w32heap.h.
3795 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3796 (get_allocation_unit, get_processor_type, get_w32_major_version)
3797 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3798 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3799 (OS_NT, os_subtype, cache_system_info): Move declarations to
3802 * w32heap.c: Include w32common.h.
3803 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3804 (w32_minor_version, w32_build_number, w32_subtype):
3805 Remove duplicate definitions.
3807 * w32fns.c: Include w32common.h; include w32heap.h only in
3810 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3811 Use `report_file_error' instead of `error' in order to better
3812 inform users of what went wrong. Increase NTGUI_UNICODE file
3813 dialog box file name length to 32k, the maximum allowed by the NT
3816 * w32common.h: New file.
3817 (ROUND_UP, ROUND_DOWN, get_page_size)
3818 (get_allocation_unit, get_processor_type, get_w32_major_version)
3819 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3820 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3821 (OS_NT, os_subtype, cache_system_info): Move here.
3823 * unexw32.c, unexcw.c: Include w32common.h.
3825 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3826 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3827 to call syms_of_w32select.
3829 * cygw32.h: Remove obsolete EXFUN declarations.
3831 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3833 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3834 of w32inevt.o from SOME_MACHINE_OBJECTS.
3836 2012-10-08 Daniel Colascione <dancol@dancol.org>
3838 * image.c: Permanent fix for JPEG compilation issue --- limit
3839 jpeglib `boolean' redefinition to Cygwin builds.
3841 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3843 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3845 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3848 2012-10-08 Daniel Colascione <dancol@dancol.org>
3850 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3851 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3852 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3853 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3854 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3855 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3856 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3857 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3858 now a supported configuration.
3860 * Makefile.in: consolidate image variables into LIBIMAGE; add
3861 W32_OBJ and W32_LIBS. Compile new files.
3864 (_DebPrint) declare tracing facility for W32 debugging. We need
3865 to unify tracing later.
3867 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3868 unconditional use of W32 Unicode functions. Cygwin runs only on
3869 100% Unicode operating systems.
3871 * cygw32.c: New file. Define Cygwin-specific facilities.
3872 (Fcygwin_convert_path_to_windows)
3873 (Fcygwin_convert_path_from_windows): New user functions for
3874 accessing Cygwin path-munging routines.
3876 * cygw32.h: New file.
3877 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3878 UTF-16LE strings temporarily inside non-Lisp-visible string
3881 (w32_strerror): Just what it says on the tin.
3883 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3884 also run for Cygwin; both systems have the same problem with using
3885 GUI facilities in a forked child. Also call syms_of_cygw32,
3886 syms_of_w32select in correct places.
3888 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3889 needs fork-then-exec for daemon launching.
3891 * font.h: Include frame.h.
3893 * image.c: Use the image library cache machinery only when we're
3894 compiling for native WINDOWSNT; Cygwin can use shared libraries
3895 like any other Unixlike system.
3897 * keyboard.c: Clarify a comment regarding the input loop.
3899 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3900 functions directly instead of trying to detect at runtime that our
3901 host operating system supports them. We make this change for two
3902 reasons: Cygwin lacks support for the multibyte character
3903 conversion functions used by the legacy menu code, and Cygwin
3904 never needs to rely on non-Unicode APIs.
3906 * unexw32.c (hinst): Declare extern.
3908 * w32.c: Change header order;
3909 (w32_strerror): Move to w32fns.c because we need it for
3910 non-WINDOWSNT builds.
3912 * w32.h: Add #error macro to make sure we don't include w32.h for
3913 Cygwin builds. Remove w32select declarations.
3915 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3916 w32fns.c. w32console.c is WINDOWSNT-only.
3918 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3919 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3921 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3922 (w32_major_version, w32_minor_version, w32_build_number)
3923 (os_subtype, sound_type): Define here
3924 (w32_defined_color): Make color parameter const for consistency
3925 with other _defined_color functions.
3926 (w32_createwindow): Unconditionally call w32_init_class instead of
3927 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3928 through the code is complex and unnecessary because class
3929 registration is practically free.
3930 (w32_name_of_message): New EMACSDEBUG-only function.
3931 (Fset_message_beep): Move here
3932 (Fx_open_connection): Require that the display name for Windows be
3933 "w32" for consistency, emacsclient disambiguation, and maybe, one
3934 day, multi-window-system support.
3935 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3936 Cygwin files for W32 GUI facilities, since these clearly don't
3937 expect Cygwin names.
3938 (_DebPrint): Define.
3939 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3940 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3941 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3942 (w32_last_error): Remove.
3944 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3946 * w32heap.c (syspage_mask): Declare here.
3947 (cache_system_info): Remove.
3949 * w32inevt.c (faked_key): Define globally, not statically.
3950 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3951 (w32_console_toggle_lock_key): Move to w32fns.c.
3953 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3955 * w32proc.c (_DebPrint): Move to w32fns.c.
3956 * w32select.c: Include string.h, stdio.h for Cygwin.
3957 * w32select.h: New File.
3959 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3961 (w32_message_fd): New variable. Under Cygwin, holds the file
3962 descriptor the system used to tell us about pending thread
3965 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3966 that prevented compilation under non-WINDOWSNT systems.
3968 (w32_initialize): Open /dev/windows and assign it to
3969 w32_message_fd. Provide w32 feature.
3971 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3972 (WM_EMACS_INPUT_READY): add.
3973 (prepend_msg, w32_message_fd): Declare globally.
3976 (keyboard_handle): Use only when WINDOWSNT.
3977 (notify_msg_ready): New function. Posts a message to the main
3978 thread's message queue under CYGWIN, which wakes up the main
3979 thread from select(2) by making the /dev/windows file descriptor
3980 ready. Under WINDOWSNT, it sets an event the same way the old
3983 (post, prepend_msg): Actually call notify_msg_ready instead of
3984 setting the input event directly.
3986 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3988 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3989 but it still has blocs in it, don't return it to the system,
3990 instead of aborting. (Bug#12402)
3992 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3994 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3996 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3997 MAC_OS_X_VERSION_10_6.
3998 (syms_of_nsterm): Remove comment about Panther and above for
4000 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4001 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4002 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4004 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4005 MAC_OS_X_VERSION_10_4.
4007 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4008 MAC_OS_X_VERSION_10_2.
4010 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4012 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4013 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4015 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4016 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4017 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4018 Remove ns_in_resize check.
4019 (ns_clear_frame_area): Remove resize handle code.
4021 * nsfns.m (ns_in_resize): Remove.
4022 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4023 Remove ns_in_resize check.
4025 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4027 Improve sys_siglist detection.
4028 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4029 defined as a macro, as is done in Solaris.
4030 (sys_siglist_entries): New macro.
4031 (save_strsignal): Use it.
4032 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4033 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4035 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4037 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4038 fullscreen/Fullscreen.
4040 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4041 tobar_height is new.
4043 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4044 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4045 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4046 (windowDidResize:): Check for correct window if old style fullscreen.
4047 Capitalize word in comment. Remove incorrect comment.
4048 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4049 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4050 error in drawing background.
4051 (toggleFullScreen:): Remove comment. Rearrange calls.
4052 Set toolbar values to zero, save old height in tobar_height.
4053 Restore tool bar height when leaving fullscreen.
4054 (canBecomeMainWindow): New function.
4056 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4058 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4060 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4062 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4064 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4065 that time stamps of directories could also be changed.
4066 Don't request the too broad GENERIC_WRITE, only the more restrictive
4067 FILE_WRITE_ATTRIBUTES access rights.
4069 * fileio.c (Fset_file_times): Special-case ignoring errors for
4070 directories only on MSDOS, not on MS-Windows.
4072 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4074 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4076 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4078 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4079 see whether CreateFile failed.
4081 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4083 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4084 to avoid similar races.
4085 * keyboard.c (pending_signals): Now bool, not int.
4087 Port timers to OpenBSD, plus check for timer failures.
4088 OpenBSD problem reported by Han Boetes.
4089 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4091 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4092 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4093 like OpenBSD, which has timer_settime but does not declare it.
4094 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4095 whether to use itimerspec-related primitives. All uses of
4096 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4098 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4100 * profiler.c (handle_profiler_signal): Fix a malloc race
4101 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4103 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4105 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4107 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4109 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4110 consistent with the change in return value of 'safe_strsignal'.
4112 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4114 Prefer plain 'static' to 'static inline' (Bug#12541).
4115 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4116 (bidi_set_sor_type, bidi_push_embedding_level)
4117 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4118 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4119 (bidi_cache_search, bidi_cache_ensure_space)
4120 (bidi_cache_iterator_state, bidi_cache_find)
4121 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4122 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4123 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4124 Now 'static', not 'static inline'.
4126 Count overruns when profiling; change units to ns.
4127 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4128 Give extra weight to samples after overruns, to attempt to count
4129 the time more accurately.
4130 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4131 the underlying primitives nominally do ns.
4132 (Fprofiler_cpu_start): Document the change. Mention that
4133 the sampling intervals are only approximate.
4135 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4137 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4139 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4140 case for the special 0 coding-system.
4142 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4143 (Fmake_overlay): Remove redundant tests.
4144 (fix_start_end_in_overlays): Remove redundant recentering.
4146 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4148 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4149 Update dependencies.
4151 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4153 Fix a malloc race condition involving strsignal.
4154 A signal can arrive in the middle of a malloc, and Emacs's signal
4155 handler can invoke strsignal, which can invoke malloc, which is
4156 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4157 Fix it by altering the signal handler so that it does not invoke
4159 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4160 * process.c (status_message): Use const pointer, in case strsignal
4161 is #defined to safe_strsignal.
4162 * sysdep.c (sys_siglist, init_signals): Always define and
4163 initialize a substitute sys_siglist if the system does not define
4164 one, even if HAVE_STRSIGNAL.
4165 (safe_strsignal): Rename from strsignal. Always define,
4166 using sys_siglist. Return a const pointer.
4167 * syssignal.h (safe_strsignal): New decl.
4168 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4170 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4172 * w32proc.c (timer_loop): Fix code that waits for timer
4173 expiration, to avoid high CPU usage.
4175 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4177 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4178 (sweep_weak_table): Remove redundant prototypes.
4180 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4182 * emacs.c: Move the inclusion of TERM_HEADER after including
4183 windows.h on WINDOWSNT. This avoids compilation problems with
4186 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4188 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4189 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4190 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4191 as the previous version used 'void *'.
4193 * ralloc.c (ROUNDUP): Fix last change.
4194 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4197 * w32proc.c <disable_itimers>: New static flag.
4198 (init_timers): Initialize it to zero, after creating the critical
4199 sections used by the timer threads.
4200 (term_timers): Set to 1 before deleting the critical sections.
4201 (getitimer, setitimer): If disable_itimers is non-zero, return an
4202 error indication without doing anything. Reported by Fabrice
4203 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4204 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4206 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4209 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4210 term_ntproc after all the other bookkeeping, to get timers working
4211 as long as possible.
4213 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4215 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4216 Suggested by Juri Linkov in
4217 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4219 Prefer plain 'static' to 'static inline' (Bug#12541).
4220 With static functions, modern compilers inline pretty well by
4221 themselves; advice from programmers often hurts as much as it helps.
4222 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4223 this change shrinks the text size of the Emacs executable by 1.1%
4224 without affecting CPU significantly in my benchmark.
4225 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4305 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4307 Revert the FOLLOW-SYMLINKS change for file-attributes.
4308 Doing it right would require several changes to Tramp, and there's
4309 not enough time to get that tested before the freeze today.
4310 * dired.c (directory_files_internal, Ffile_attributes):
4313 * frame.c (x_report_frame_params): Port better to wider ints.
4314 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4315 or that pointers can be printed in 15 decimal digits.
4316 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4352 * vm-limit.c (lim_data): Now size_t.
4353 (check_memory_limits): Adjust prototypes of real_morecore and
4354 __morecore to receive argument of type ptrdiff_t. Use size_t for

4423 Windows-specific code to display the hourglass mouse pointer is no
4425 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
4426 to hourglass timer expiration.

4507 Profiler improvements: more-accurate timers, overflow checks.
4508 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4509 signal.h, setjmp.h. Include systime.h instead.
4510 (saturated_add): New function.

4517 All uses changed to store the new value.
4518 (handle_profiler_signal): Rename from sigprof_handler_1,
4519 for consistency with other handlers. Do not check whether
4520 cpu_log is a hash-table if garbage collecting, since it
4521 doesn't matter in that case.

4523 for consistency with other handlers.
4524 (setup_cpu_timer): New function, with much of what used to be in
4525 Fprofiler_cpu_start. Check for out-of-range argument.
4526 Prefer timer_settime if available, and prefer
4527 thread cputime clocks, then process cputime clocks, then
4528 monotonic clocks, to the old realtime clock. Use make_timeval
4529 to round more-correctly when falling back to setitimer.
4530 (Fprofiler_cpu_start): Use it.
4531 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4532 Don't assume that passing NULL as the 2nd argument of setitimer
4533 is the same as passing a pointer to all-zero storage.
4534 Ignore SIGPROF afterwards.
4535 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4536 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4537 non-fatal signal handlers. Ignore SIGPROF on startup.
4538 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4539 in profiler.c, since sysdep.c now uses it.
4541 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4597 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4598 Since this stuff is now private to charset.c, there's no need for
4599 a public macro and no need to inline by hand.

4628 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4630 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4632 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4634 Prefer POSIX timers if available.
4635 They avoid a race if the timer is too close to the current time.
4636 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4637 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4638 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4640 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4642 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
4643 CHAR_STRING_ADVANCE.
4644 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4645 STRING_CHAR_ADVANCE.
4647 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4649 Move Vlibrary_cache to emacs.c and reset before dumping.
4651 * lisp.h (reset_image_types): Declare.
4652 [WINDOWSNT] (Vlibrary_cache): Declare.
4654 * image.c (reset_image_types): New function.
4656 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
4657 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
4658 (Fdump_emacs): Reset Vlibrary_cache and image_types.
4660 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
4661 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
4663 * w32.h (Vlibrary_cache): Do not declare.
4665 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4667 * w32proc.c (sys_signal): Handle all signals defined by the
4668 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4669 handlers for signals supported by Windows. Don't override
4670 term_ntproc as the handler for SIGABRT.
4671 (sigaction): Rewrite to call sys_signal instead of duplicating its
4673 (sys_kill): Improve commentary.
4675 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4676 consistency with a signature of a signal handler. All callers
4678 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4679 install term_ntproc as a signal handler for SIGABRT, as that
4680 should be done by the dumped Emacs.
4682 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4684 * w32select.c (term_w32select): Protect against repeated
4685 invocation by setting clipboard_owner to NULL after calling
4688 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4689 and term_ntproc to their modified signatures.
4691 * character.c (char_string, string_char): Remove calls to
4692 MAYBE_UNIFY_CHAR. See the discussion starting at
4693 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4696 2012-09-25 Chong Yidong <cyd@gnu.org>
4698 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4700 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4702 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4703 when encountering an unknown bytecode.
4705 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4707 image.c, indent.c: Use bool for booleans.
4708 * dispextern.h (struct image_type): Members valid_p, load, init
4709 now return bool, not int. All uses changed.
4710 * image.c: Omit unnecessary static decls.
4711 (x_create_bitmap_mask, x_build_heuristic_mask):
4712 Return void, not int, since callers don't care about the return value.

4741 Use bool for booleans.
4743 2012-09-24 Chong Yidong <cyd@gnu.org>
4745 * chartab.c (Fset_char_table_default): Obsolete function removed.
4747 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4749 Move pid_t related decls out of lisp.h.
4750 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4751 (interruptible_wait_for_termination):
4752 Move these decls from lisp.h to syswait.h, since they use pid_t.
4753 Needed on FreeBSD; see Herbert J. Skuhra in
4754 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4755 * callproc.c: Include syswait.h.
4757 gnutls.c, gtkutil.c: Use bool for boolean.

4772 * nsmenu.m (ns_update_menubar):
4773 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4774 * xfns.c (Fx_show_tip) [USE_GTK]:
4775 Use bool for boolean.
4776 * gtkutil.c (xg_update_frame_menubar):
4777 * xmenu.c (update_frame_menubar):
4778 Return void, not int, since caller ignores return value.
4779 * gtkutil.c (xg_change_toolbar_position):
4782 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4784 * makefile.w32-in (BLOCKINPUT_H): Remove.

4801 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4803 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4804 fatal_error_backtrace.
4806 * w32proc.c (sys_kill): Undo last change: don't do anything when
4807 invoked to deliver SIGABRT to our own process. This is now
4808 handled by emacs_raise.
4810 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4812 * w32term.c (w32_read_socket): Remove leftover reference to
4813 interrupt_input_pending.
4815 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4817 Do not use SA_NODEFER.
4818 Problem reported by Dani Moncayo in
4819 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4821 * sysdep.c (emacs_abort): Do not reset signal handler.
4822 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4823 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4824 wanted even on POSIXish hosts, and it doesn't work on Windows.
4826 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4828 * xterm.c (x_term_init): Call fixup_locale before and after calling
4829 gtk_init (Bug#12392).
4831 2012-09-23 Chong Yidong <cyd@gnu.org>
4833 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4834 Vdynamic_library_alist.
4836 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4837 (Fgnutls_available_p): Caller changed.
4839 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4840 (Flibxml_parse_xml_region): Likewise.
4842 * dispextern.h (struct image_type): Remove arg from init function.
4844 * image.c (Finit_image_library, lookup_image_type)
4845 (define_image_type): Remove now-unneeded second arg.
4846 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4847 (init_tiff_functions, init_gif_functions, init_svg_functions):
4848 Arglist and w32_delayed_load calling convention changed.
4849 (gs_type): Remove init_gs_functions; there is no such function.
4850 (valid_image_p, make_image): Fix caller to lookup_image_type.
4852 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4854 Simplify and avoid signal-handling races (Bug#12471).
4856 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4857 Avoid recursive loop if there's a fatal error in the function itself.
4858 * atimer.c (pending_atimers):
4859 * blockinput.h: Don't include "atimer.h"; no longer needed.
4860 (interrupt_input_pending): Remove. All uses removed.
4861 pending_signals now counts both atimers and ordinary interrupts.
4862 This is less racy than having three separate pending-signal flags.
4863 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4865 Rename from their upper-case counterparts BLOCK_INPUT,
4866 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4867 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4868 This makes it easier to access volatile variables more accurately.
4869 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4870 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4871 that's more reliable if the code is buggy and sets
4872 interrupt_input_blocked to a negative value. All uses changed.
4873 * atimer.c (deliver_alarm_signal):
4874 Remove. No need to deliver this to the parent; any thread can
4875 handle this signal now. All uses replaced by underlying handler.
4876 * atimer.c (turn_on_atimers):
4877 * dispnew.c (handle_window_change_signal):
4878 * emacs.c (handle_danger_signal):
4879 * keyboard.c (kbd_buffer_get_event):
4880 Don't reestablish signal handler; not needed with sigaction.
4881 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4883 Rework to avoid unnecessary accesses to volatile variables.
4884 (UNBLOCK_INPUT_TO): Now a function.
4885 (totally_unblock_input, unblock_input): New decls.
4886 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4887 (init_data): Remove. Necessary stuff now done in init_signal.
4888 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4889 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4890 (fatal_error_code): Remove; no longer needed.
4891 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4892 it doesn't always backtrace. All uses changed. No need to reset
4893 signal to default, since sigaction and/or die does that for us now.
4894 Use emacs_raise (FOO), not kill (getpid (), FOO).
4895 (main): Check more-accurately whether we're dumping.
4896 Move fatal-error setup to sysdep.c
4897 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4898 * gtkutil.c (xg_get_file_name, xg_get_font):
4899 Remove no-longer-needed signal-mask manipulation.
4900 * keyboard.c, process.c (POLL_FOR_INPUT):
4901 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4902 * keyboard.c (read_avail_input): Remove.
4903 All uses replaced by gobble_input.
4904 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4905 (kbd_buffer_store_event_hold, gobble_input):
4906 (record_asynch_buffer_change) [USABLE_SIGIO]:
4907 (store_user_signal_events):
4908 No need to mess with signal mask.
4909 (gobble_input): If blocking input and there are terminals, simply
4910 set pending_signals to 1 and return. All hooks changed to not
4911 worry about whether input is blocked.
4912 (process_pending_signals): Clear pending_signals before processing
4913 them, in case a signal comes in while we're processing.
4914 By convention callers now test pending_signals before calling us.
4915 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4916 New functions, to support changes to blockinput.h.
4917 (handle_input_available_signal): Now extern.
4918 (reinvoke_input_signal): Remove. All uses replaced by
4920 (quit_count): Now volatile, since a signal handler uses it.
4921 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4922 All callers changed. Block SIGINT only if not already blocked.
4923 Clear sigmask reliably, even if Fsignal returns, which it can.
4924 Omit unnecessary accesses to volatile var.
4925 (quit_throw_to_read_char): No need to restore sigmask.
4926 * keyboard.c (gobble_input, handle_user_signal):
4927 * process.c (wait_reading_process_output):
4928 Call signal-handling code rather than killing ourselves.
4929 * lisp.h: Include <float.h>, for...
4930 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4931 (pending_signals): Now volatile.
4932 (syms_of_data): Now const if IEEE floating point.
4933 (handle_input_available_signal) [USABLE_SIGIO]:
4934 (terminate_due_to_signal, record_child_status_change): New decls.
4935 * process.c (create_process): Avoid disaster if memory is exhausted
4936 while we're processing a vfork, by tightening the critical section
4938 (send_process_frame, process_sent_to, handle_pipe_signal)
4939 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4941 (send_process): No need for setjmp/longjmp any more, since the
4942 SIGPIPE stuff is now gone. Instead, report an error if errno
4944 (record_child_status_change): Now extern. PID and W are now args.
4945 Return void, not bool. All callers changed.
4946 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4947 Remove. All uses removed. This bug should be fixed now in a
4949 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4950 and record the child status change directly. This avoids the
4951 need to futz with the signal mask.
4952 (process_fatal_action): Move here from emacs.c.
4953 (emacs_sigaction_flags): New function, containing
4954 much of what used to be in emacs_sigaction_init.
4955 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4956 caught by emacs, to make races less likely.
4957 (deliver_process_signal): Rename from handle_on_main_thread.
4959 (BACKTRACE_LIMIT_MAX): Now at top level.
4960 (thread_backtrace_buffer, threadback_backtrace_pointers):
4962 (deliver_thread_signal, deliver_fatal_thread_signal):
4963 New functions, for more-accurate delivery of thread-specific signals.
4964 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4965 (deliver_arith_signal): Handle in this thread, not
4966 in the main thread, since it's triggered by this thread.
4967 (maybe_fatal_sig): New function.
4968 (init_signals): New arg DUMPING so that we can be more accurate
4969 about whether we're dumping. Caller changed.
4970 Treat thread-specific signals differently from process-general signals.
4971 Block all signals while handling fatal error; that's safer.
4972 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4974 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4975 Ignore SIGPIPE unless batch.
4976 (emacs_backtrace): Output backtrace for the appropriate thread,
4977 which is not necessarily the main thread.
4978 * syssignal.h: Include <stdbool.h>.
4979 (emacs_raise): New macro.
4980 * xterm.c (x_connection_signal): Remove; no longer needed
4981 now that we use sigaction.
4982 (x_connection_closed): No need to mess with sigmask now.
4983 (x_initialize): No need to reset SIGPIPE handler here, since
4984 init_signals does this for us now.
4986 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4988 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4989 background rect may be larger (Bug#12245).
4991 2012-09-23 Chong Yidong <cyd@gnu.org>
4993 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4995 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4997 * .gdbinit: Just stop at fatal_error_backtrace.
4998 See Stefan Monnier's request in
4999 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5000 Remove no-longer-used query of system type.
5002 2012-09-22 Chong Yidong <cyd@gnu.org>
5004 * search.c (Freplace_match): Doc fix (Bug#12325).
5006 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5008 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5009 (Fline_end_position): Doc fix.
5011 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5013 2012-09-22 Chong Yidong <cyd@gnu.org>
5015 * dispextern.h (struct image_type): Add new slot, storing a type
5016 initialization function.
5018 * image.c (define_image_type): Call the image initializer function
5019 if it is defined. Arguments and return value changed.
5020 (valid_image_p, make_image): Callers changed.
5021 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5022 (gif_type, imagemagick_type, svg_type, gs_type):
5023 Add initialization functions.
5024 (Finit_image_library): Call lookup_image_type.
5025 (CHECK_LIB_AVAILABLE): Macro deleted.
5026 (lookup_image_type): Call define_image_type here, rather than via
5027 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5028 (syms_of_image): Move define_image_type calls for xbm_type and
5029 pbm_type to lookup_image_type.
5031 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5033 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5034 'idle_timers' from here ...
5035 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5036 lists, to avoid infloops when the timer does something stupid,
5037 like reinvoke itself with the same or smaller time-out.
5040 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5042 * window.c (Fsplit_window_internal): Handle only Qt value of
5043 Vwindow_combination_limit separately.
5044 (Qtemp_buffer_resize): New symbol.
5045 (Vwindow_combination_limit): New default value.
5048 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5050 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5051 the new overlay string. (Bug#10159)
5053 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5055 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5056 or that fprintf is async-signal-safe. POSIX doesn't require
5059 2012-09-22 Chong Yidong <cyd@gnu.org>
5061 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5064 2012-09-22 Kenichi Handa <handa@gnu.org>
5066 * composite.c (composition_reseat_it): Handle the case that a
5067 grapheme cluster is not covered by a single font (Bug#12352).
5069 2012-09-21 Chong Yidong <cyd@gnu.org>
5071 * image.c (define_image_type): Avoid adding duplicate types to
5072 image_types (Bug#12463). Suggested by Jörg Walter.
5074 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5076 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5077 (print_load_command_name): Add case LC_DATA_IN_CODE.
5078 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5080 2012-09-21 Glenn Morris <rgm@gnu.org>
5082 * eval.c (Frun_hook_with_args_until_success)
5083 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5085 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5087 * fileio.c (Ffile_selinux_context): Only call freecon when
5088 lgetfilecon succeeded.
5089 (Fset_file_selinux_context): Likewise. (Bug#12444)
5091 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5093 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5094 reordering, locate the cursor by calling set_cursor_from_row; if
5095 that fails, clear the desired glyph matrix before returning a
5096 failure indication to the caller. Fixes leaving garbled display
5097 when fast scrolling with a down-key. (Bug#12403)
5098 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5099 scrolling through multibyte text.
5101 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5103 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5104 calling mark_vectorlike since that's the one that marks the window.
5105 (mark_discard_killed_buffers): Mark the final cdr.
5106 * window.h (struct window): Move prev/next_buffers to the
5107 non-standard fields.
5108 * window.c (make_window): Initialize prev/next_buffers manually.
5110 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5112 Omit unused arg EXPECTED from socket hooks.
5113 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5114 * nsterm.m (ns_term_init):
5115 * termhooks.h (struct terminal.read_socket_hook):
5116 * w32inevt.c (w32_console_read_socket):
5117 * w32term.c (w32_read_socket):
5118 * xterm.c (XTread_socket):
5119 Omit unused arg EXPECTED. All callers changed.
5120 (store_user_signal_events): Return void, not int, since callers no
5121 longer care about the return value. All uses changed.
5123 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5125 * w32gui.h (XParseGeometry): Do not declare.
5127 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5129 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5130 Ignore 'expected'. See Eli Zaretskii in
5131 <http://bugs.gnu.org/12471#8> (last line).
5133 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5134 (XParseGeometry): Now static. Substitute extremal values for
5135 values that are out of range.
5137 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5139 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5141 * nsfns.m (XParseGeometry): Remove.
5142 (Fx_create_frame): Call x_set_offset to correctly interpret
5143 top_pos in geometry.
5145 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5146 (Fx_parse_geometry): If there is a space in string, call
5147 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5149 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5151 * search.c (scan_buffer): Use character positions in calls to
5152 region_cache_forward and region_cache_backward, not byte
5153 positions. (Bug#12196)
5155 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5156 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5158 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5159 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5160 emacs_blocked_malloc, now deleted.
5162 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5164 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5165 The workaround was for improving performance on Solaris 2.4, but
5166 is getting in the way now. Emacs will still work if someone is
5167 still running Solaris 2.4 in a museum somewhere; Sun dropped
5168 support for Solaris 2.4 in 2003.
5169 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5170 * process.c (create_process) [HAVE_WORKING_VFORK]:
5171 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5172 since Emacs no longer uses vfork on that platform.
5174 2012-09-17 Glenn Morris <rgm@gnu.org>
5176 * emacs.c: Use COPYRIGHT.
5178 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5180 Remove configure's --without-sync-input option (Bug#12450).
5181 When auditing signal-handling in preparation for cleaning it up,
5182 I found that SYNC_INPUT has race conditions and would be a real
5183 pain to fix. Since it's an undocumented and deprecated
5184 configure-time option, now seems like a good time to remove it.
5185 Also see <http://bugs.gnu.org/11080#16>.
5186 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5187 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5188 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5189 (malloc_hysteresis):
5190 (check_depth) [XMALLOC_OVERRUN_CHECK]:

5195 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5196 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5197 Remove. All uses removed.
5198 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5199 implementation, one that depends on whether the new macro
5200 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5202 * atimer.c (run_timers, handle_alarm_signal):
5203 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5204 (handle_async_input, process_pending_signals)
5205 (handle_input_available_signal, init_keyboard):
5206 * nsterm.m (ns_read_socket):

5211 * xterm.c (XTread_socket):
5213 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5214 * eval.c (handling_signal): Remove. All uses removed.
5215 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5216 All uses replaced with the SYNC_INPUT version.
5217 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5219 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5222 * font.c (Ffont_shape_gstring): Remove unused local.
5224 2012-09-16 Glenn Morris <rgm@gnu.org>
5226 * Makefile.in (clean): No longer run nextstep's clean.
5228 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5230 (ns-app): Move here from ns.mk, and simplify.
5231 (clean): Simplify nextstep entry.
5232 * ns.mk: Remove file.
5234 2012-09-17 Kenichi Handa <handa@gnu.org>
5236 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5237 not covert the last few charactes.
5239 2012-09-16 Kenichi Handa <handa@gnu.org>
5241 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5242 here, but just check the validity of glyphs in the glyph-string.
5244 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5246 * window.c (Fwindow_parameter, Fset_window_parameter):
5247 Accept any window as argument (Bug#12452).
5249 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5251 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5252 to ns_term_init to avoid memory leak.
5254 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5255 explicit retain/release.
5256 (ns_term_init): Only allow one display. Initialize outerpool and
5259 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5261 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5262 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5263 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5264 the Microsoft problem in a different way, by altering ../nt/config.nt.
5266 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5281 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5282 by lisp.h. This completes removal of setjmp.h inclusion
5283 erroneously announced in the previous commit. (Bug#12446)
5285 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5288 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5289 not defined as a macro. The latter happens on MS-Windows.
5292 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5294 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5295 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5296 Some instances of '#include <setjmp.h>' removed, if the
5297 only reason for the instance was because "lisp.h" was included.
5298 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5299 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5300 and _longjmp with the new symbols. Emacs already uses _setjmp if
5301 available, so this change affects only POSIXish hosts that have
5302 sigsetjmp but not _setjmp, such as some versions of Solaris and
5303 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5304 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5305 (png_load_body) [HAVE_PNG]:
5306 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5307 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5308 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5309 since PNG requires jmp_buf. This is the only exception to the
5310 general rule that we now use sys_setjmp and sys_longjmp.
5311 This exception is OK since this code does not change the signal
5312 mask or longjmp out of a signal handler.
5314 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5316 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5317 Include "syssignal.h", for 'main_thread'.
5319 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5321 Avoid out-of-range marker position (Bug#12426).
5322 * insdel.c (replace_range, replace_range_2):
5323 Adjust markers before overlays, as suggested by comments.
5324 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5325 Remove redundant check before calling offset_intervals.
5327 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5329 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5330 current buffer (Bug#12387).
5332 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5334 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5336 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5338 Use a more backwards-compatible timer format (Bug#12430).
5339 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5340 vector element, not from the 4th, since PSECS is now at the end.
5341 (Fcurrent_idle_time): Doc fix.
5343 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5345 Function to mark objects and remove killed buffers at once.
5346 * alloc.c (discard_killed_buffers): Rename to ...
5347 (mark_discard_killed buffers) ... new name. Add marking
5348 of remaining objects. Fix comment. Adjust users.
5349 (mark_object): Do not touch frame buffer lists here.
5350 * frame.c (delete_frame): Reset frame buffer lists here.
5352 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5354 Better workaround for GNOME bug when --enable-gcc-warnings.
5355 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5356 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5357 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5359 Simplify SIGIO usage (Bug#12408).
5360 The code that dealt with SIGIO was crufty and confusing, e.g., it
5361 played tricks like "#undef SIGIO" but these tricks were not used
5362 consistently. Simplify mostly by not #undeffing standard symbols,
5363 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5364 or not as we please) rather than "defined SIGIO" (standard symbol
5365 that we probably shouldn't #undef).
5366 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5367 Modules that need it can include it.
5368 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5369 * dispextern.h (ignore_sigio): New decl.
5370 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5371 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5372 * emacs.c (shut_down_emacs):
5373 * keyboard.c (kbd_buffer_store_event_hold):
5374 Use ignore_sigio rather than invoking 'signal' directly.
5375 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5377 (FIONREAD, SIGIO): Do not #undef.
5378 (tty_read_avail_input): Use #error rather than a syntax error.
5379 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5380 for I_PIPE, used by SETUP_SLAVE_PTY.
5381 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5382 * sysdep.c (croak): Remove; no longer needed. This bit of
5383 temporary code, with Fred N. Fish's comment that it's temporary,
5384 has been in Emacs since at least 1992!
5385 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5386 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5387 * syssignal.h (croak): Remove decl.
5388 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5389 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5390 now that we're termios-only.
5391 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5392 * term.c (dissociate_if_controlling_tty): Use #error rather than
5395 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5396 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5397 to work around GNOME bug 683906.
5398 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5399 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5400 This works around GCC bug 54561.
5402 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5404 More fixes for 'volatile' and setjmp/longjmp.
5405 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5406 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5407 (png_load_body) [HAVE_PNG]:
5408 (jpeg_load_body) [HAVE_JPEG]:
5409 New function, with most of the old parent function's body.
5410 (png_load) [HAVE_PNG]:
5411 (jpeg_load) [HAVE_JPEG]:
5412 Invoke the new function, to avoid longjmp munging our locals.
5413 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5414 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5415 longjmp is passed 2, as the C standard doesn't guarantee this.
5416 Instead, store the failure code into mgr->failure_code.
5418 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5420 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5421 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5422 (syms_of_keyboard): Remove support for unread-command-char.
5424 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5426 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5427 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5428 violation. (Bug#12426)
5430 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5432 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5434 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5436 * eval.c: Add `inhibit-debugger'.
5437 (Qinhibit_debugger): New symbol.
5438 (call_debugger): Bind it instead of Qdebug_on_error.
5439 (maybe_call_debugger): Test Vinhibit_debugger.
5440 (syms_of_eval): Define inhibit-debugger.
5441 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5442 (syms_of_xdisp): Remove inhibit-debug-on-message.
5444 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5446 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5447 If a nonvolatile local variable is written before a _longjmp to
5448 the frame containing the variable, and is read after the _longjmp,
5449 the value read is indeterminate. Some local variables of type
5450 'struct handler' and 'struct catchtag' are used in this way, so
5451 mark each of their slots as volatile if the slot can be set before
5452 _longjmp and read afterwards.
5453 * lisp.h (struct handler): var and chosen_clause are now volatile.
5454 (struct catchtag): val, next, and pdlcount are now volatile.
5456 * bidi.c (bidi_push_it, bidi_pop_it):
5457 * fns.c (copy_hash_table):
5458 * image.c (define_image_type):
5459 * keyboard.c (kbd_buffer_store_event_hold):
5460 * process.c (Fprocess_send_eof):
5461 * xfaces.c (x_create_gc) [HAVE_NS]:
5462 * xgselect.c (xg_select):
5463 Prefer assignment to memcpy when either will do.
5465 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5466 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5467 time an item is removed. No need to mark this function 'inline';
5468 the compiler knows better than we do.
5470 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5472 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5473 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5474 to change_frame_size (Bug#12388).
5475 (windowDidResize:): Pass YES to updateFrameSize.
5477 * nsterm.h: Add delay parameter to updateFrameSize.
5479 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5481 Discard killed buffers from deleted window and frame objects.
5482 This reduces an amount of references to killed buffers and
5483 helps GC to reclaim them faster.
5484 * alloc.c (discard_killed_buffers): New function.
5485 (mark_object): Use it for deleted windows and frames.
5486 (mark_object): If symbol's value is set up for a killed buffer
5487 or deleted frame, restore its global binding.
5488 * data.c (swap_in_global_binding): Add GC notice.
5489 (swap_in_symval_forwarding): Use convenient set_blv_where.
5490 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5491 * window.h: ... to here.
5493 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5495 Convenient macro to check whether the buffer is live.
5496 * buffer.h (BUFFER_LIVE_P): New macro.
5497 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5498 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5500 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5502 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5503 composition cases (Bug#12364).
5505 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5506 overhang of succeeding glyphs overlapping box cursor.
5508 * w32term.c (x_draw_glyph_string): Likewise.
5510 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5512 Simplify, document, and port floating-point (Bug#12381).
5513 The porting part of this patch fixes bugs on non-IEEE platforms
5514 with frexp, ldexp, logb.
5515 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5517 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5518 support, by removing commented-out code and briefly listing the
5519 C89 functions excluded. The commented-out stuff was confusing
5520 maintenance, e.g., we thought we needed cbrt but it was commented out.
5521 (logb): Remove decl; no longer needed.
5522 (isfinite): New macro, if not already supplied.
5523 (isnan): Don't replace any existing macro.
5524 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5525 are present on all C89 platforms.
5526 (Ffrexp): Do not special-case zero, as frexp does the right thing
5528 (Flogb): Do not use logb, as it doesn't have the desired meaning
5529 on hosts that use non-base-2 floating point. Instead, stick with
5530 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5531 frexp, to avoid getting an unspecified result.
5533 * xdisp.c (Qinhibit_debug_on_message): Now static.
5535 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5537 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5538 NSBezierPath (Bug#12131).
5540 2012-09-10 Chong Yidong <cyd@gnu.org>
5542 * fns.c (Fdelq, Fdelete): Doc fix.
5544 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5546 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5547 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5549 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5551 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5552 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5555 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5557 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5558 left fringe if the window has a left margin. This avoids leaving
5559 traces of the cursor because its leftmost pixel is not drawn over.
5561 * dispnew.c (update_window_line): When the left margin area of a
5562 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5563 that screen line. (Bug#12277)
5565 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5567 Assume C89 or later for math functions (Bug#12381).
5568 This simplifies the code, and makes it a bit smaller and faster,
5569 and (most important) makes it easier to clean up signal handling
5570 since we can stop worring about floating-point exceptions in
5571 library code. That was a problem before C89, but the problem
5572 went away many years ago on all practical Emacs targets.
5573 * data.c, image.c, lread.c, print.c:
5574 Don't include <math.h>; no longer needed.
5575 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5576 might be autoconfigured, as that never happens.
5578 * doprnt.c (DBL_MAX_10_EXP):
5579 * print.c (DBL_DIG):
5580 Remove. C89 or later always defines these.
5581 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5582 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5583 (arith_error, domain_error, domain_error2):
5584 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5585 no longer needed -- we simply return what C returns. All uses removed.
5586 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5588 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5589 Remove. All uses expanded, as these macros are no longer used
5590 more than once and are now more trouble than they're worth.
5591 (Ftan): Use tan, not sin / cos.
5592 (Flogb): Assume C89 frexp.
5593 (fmod_float): Assume C89 fmod.
5594 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5595 (init_floatfns): Remove. All uses removed.
5597 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5599 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5600 compositeToPoint for OSX < 10.6 (Bug#12390).
5602 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5604 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5605 This produces more-accurate results.
5607 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5609 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5610 changes (Bug#12088).
5612 2012-09-08 Chong Yidong <cyd@gnu.org>
5614 * syntax.c (Fstring_to_syntax): Doc fix.
5616 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5618 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5619 in the internal border.
5620 (x_set_window_size): Remove static variables and their usage.
5621 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5622 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5623 Remove fringe/internal border adjustment (Bug#11052).
5624 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5625 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5626 (ns_fix_rect_ibw): Remove.
5627 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5628 (ns_dumpglyphs_box_or_relief): Ditto.
5629 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5631 (ns_dumpglyphs_image): Ditto.
5632 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5634 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5635 their usage. Add fringe_extended_p and its use as in other terms.
5636 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5637 scroll bar was removed.
5638 (updateFrameSize): New function.
5639 (windowDidResize): Move code to updateFrameSize and call it.
5641 * nsterm.h (EmacsView): Add updateFrameSize.
5643 2012-09-07 Chong Yidong <cyd@gnu.org>
5645 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5647 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5649 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5651 More signal-handler cleanup (Bug#12327).
5652 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5653 Problem introduced when merging patches. Noted by Eli Zaretskii in
5654 <http://bugs.gnu.org/12327#67>.
5655 * floatfns.c: Comment fix.
5656 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5657 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5658 and anyway the declaration is harmless even if SIGDANGER is not defined.
5659 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5660 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5661 source files not surprisingly expected syssignal.h to define, or
5662 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5663 Include <sys/ioctl.h>, for FIONREAD.
5664 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5665 This eliminates a problem whereby other files mysteriously had
5666 to include "syssignal.h" before including "systty.h" if they
5667 wanted to use "#ifdef SIGIO".
5669 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5671 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5673 * w32.c (sigemptyset): Empty the set.
5674 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5676 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5678 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5680 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5681 (mark_object): Likewise for frame objects.
5683 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5685 * syssignal.h (handle_on_main_thread): Always declare,
5686 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5687 This ports to platforms without HAVE_PTHREAD.
5689 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5691 Signal-handler cleanup (Bug#12327).
5692 Emacs's signal handlers were written in the old 4.2BSD style with
5693 sigblock and sigmask and so forth, and this led to some
5694 inefficiencies and confusion. Rewrite these to use
5695 pthread_sigmask etc. without copying signal sets around. Also,
5696 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5697 'signal', and instead use functions that do not attempt to take
5698 over the system name space. This patch causes Emacs's text
5699 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5700 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5701 Do not include <signal.h> or "syssignal.h", as these
5702 modules do not use signals.
5703 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5704 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5705 Do not include <signal.h>, as "syssignal.h" does that for us now.
5706 * atimer.c (sigmask_atimers): New function.
5707 (block_atimers, unblock_atimers): New functions,
5708 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5710 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5711 no longer needed here.
5712 * emacs.c (main): Inspect existing signal handler with sigaction,
5713 so that there's no need to block and unblock SIGHUP.
5714 * sysdep.c (struct save_signal): New member 'action', replacing
5715 old member 'handler'.
5716 (save_signal_handlers, restore_signal_handlers):
5717 Use sigaction instead of 'signal' to save and restore.
5718 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5719 New function. All users of 'signal' modified to use set_sighandler
5720 if they're writeonly, and to use sys_signal if they're read+write.
5721 (emacs_sigaction_init, forwarded_signal): New functions.
5722 (sys_signal): Remove. All uses replaced by calls to sigaction
5723 and emacs_sigaction_init, or by direct calls to 'signal'.
5724 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5725 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5726 all uses replaced by pthread_sigmask etc. calls.
5727 * syssignal.h: Include <signal.h>.
5728 (emacs_sigaction_init, forwarded_signal): New decls.
5729 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5730 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5731 (sigmask, sys_sigmask): Remove; no longer needed.
5732 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5733 (sigblock, sigunblock, sigfree):
5734 (sigsetmask) [!defined sigsetmask]:
5735 Remove. All uses replaced by pthread_sigmask.
5736 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5737 no longer need to be replaced, and its typical old uses
5738 are now done via emacs_sigaction_init and sigaction.
5739 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5740 (sys_sigdel): Remove; unused.
5741 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5743 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5745 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5746 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5748 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5750 Explicitly mark buffer_defaults and buffer_local_symbols.
5751 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5752 mark_local_symbols here.
5753 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5754 since special buffers aren't marked here any more.
5755 (allocate_buffer): Chain new buffer with all_buffers here...
5756 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5758 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5759 (syms_of_buffer): Remove staticpro of the above.
5760 (init_buffer_once): Set names for buffer_defaults and
5761 buffer_local_symbols.
5763 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5765 Use bool for booleans in font-related modules.
5766 * font.c (font_intern_prop, font_style_to_value)
5767 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5768 (generate_otf_features, font_check_otf_features, font_check_otf)
5769 (font_match_p, font_list_entities, font_at):
5770 * fontset.c (fontset_id_valid_p, reorder_font_vector
5771 (fontset_find_font, Fset_fontset_font)
5772 (face_suitable_for_char_p) [0]:
5773 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5774 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5775 (m17n_flt_initialized, ftfont_shape_by_flt):
5776 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5777 * nsfont.m (nsfont_draw):
5778 * w32font.c (w32font_draw):
5779 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5780 Use bool for booleans.
5781 * font.h: Adjust to above API changes.
5782 (struct font, struct font_driver, struct font_driver_list):
5783 Use bool for booleans.
5784 (struct font): Remove useless member encoding_type.
5786 * fontset.c, xftfont.c: Omit unnecessary static decls.
5788 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5790 * alloc.c (mark_object): Revert window marking code
5791 since it's unsafe for the Fset_window_configuration.
5793 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5795 Fix race conditions with signal handlers and errno (Bug#12327).
5796 Be more systematic about preserving errno whenever a signal
5797 handler returns, even if it's not in the main thread. Do this by
5798 renaming signal handlers to distinguish between signal delivery
5799 and signal handling. All uses changed.
5800 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5801 * data.c (deliver_arith_signal): Rename from arith_error.
5802 * dispnew.c (deliver_window_change_signal): Rename from
5803 window_change_signal.
5804 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5805 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5806 * keyboard.c (deliver_input_available_signal): Rename from
5807 input_available_signal.
5808 (deliver_user_signal): Rename from handle_user_signal.
5809 (deliver_interrupt_signal): Rename from interrupt_signal.
5810 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5811 (deliver_child_signal): Rename from sigchld_handler.
5812 * atimer.c (handle_alarm_signal):
5813 * data.c (handle_arith_signal):
5814 * dispnew.c (handle_window_change_signal):
5815 * emacs.c (handle_fatal_signal, handle_danger_signal):
5816 * keyboard.c (handle_input_available_signal):
5817 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5818 * process.c (handle_pipe_signal, handle_child_signal):
5819 New functions, with the actual signal-handling code taken from the
5820 original respective signal handlers, sans the sporadic attempts to
5821 preserve errno, since that's now done by handle_on_main_thread.
5822 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5823 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5824 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5826 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5827 Move initialization of main_thread to sysdep.c's init_signals.
5828 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5829 our usage, and simplifies the mainline code.
5830 (record_child_status_change): New static function, as a helper
5831 for handle_child_signal, and with most of the old child handler's
5833 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5834 (handle_child_signal): Use the above.
5835 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5836 Moved here from emacs.c.
5837 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5838 code moved here from emacs.c's main function.
5839 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5840 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5841 This lets callers save and restore errno properly.
5843 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5845 Remove redundant or unused things here and there.
5846 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5847 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5848 * editfns.c (Fcompare_buffer_substrings): Likewise.
5849 * frame.h (struct terminal, struct font_driver_list):
5850 Remove redundant declarations.
5851 * window.h (Qleft, Qright): Likewise.
5853 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5855 Do not mark objects from deleted buffers, windows and frames.
5856 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5857 (mark_object): Likewise for windows and frames.
5859 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5861 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5862 buffer_defaults and buffer_local_symbols as valid objects.
5863 Return special value to denote them.
5865 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5867 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5868 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5869 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5870 (file_name_absolute_p, Fsubstitute_in_file_name):
5871 (check_executable, check_writable, Ffile_accessible_directory_p)
5872 (Fset_file_selinux_context, Fdefault_file_modes)
5873 (Finsert_file_contents, choose_write_coding_system)
5874 (Fwrite_region, build_annotations, a_write, e_write)
5876 * filelock.c (boot_time_initialized, get_boot_time)
5877 (get_boot_time_1, lock_file_1, within_one_second):
5878 * floatfns.c (in_float):
5879 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5880 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5881 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5882 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5883 * window.c (compare_window_configurations):
5884 Use bool for booleans.
5885 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5886 (Fdefault_file_modes): Now mode_t, not int, for modes.
5887 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5888 (internal_delete_file): Now returns void, not a (boolean) int,
5889 since nobody was looking at the return value.
5890 * lisp.h, window.h: Adjust to above API changes.
5892 * xdisp.c (set_message): Simplify and reindent last change.
5894 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5896 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5898 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5900 * eval.c (call_debugger): Make the function non-static so that we
5901 can call it from set_message.
5903 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5904 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5906 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5908 Give more-useful info on a fatal error (Bug#12328).
5909 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5910 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5911 of doing the work ourselves.
5912 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5913 do most of the work.
5914 (fatal_error_backtrace): New function, taken from the guts
5915 of the old fatal_error_signal, but with a new option to output
5917 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5918 info about the signal than just its number.
5919 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5920 * sysdep.c: Include <execinfo.h>
5921 (emacs_backtrace): New function, taken partly from the previous
5922 code of the 'die' function.
5923 (emacs_abort): Call fatal_error_backtrace rather than abort.
5925 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5927 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5928 eager (load-time) macro-expansion.
5929 * lisp.mk (lisp): Add macroexp.
5931 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5933 Simplify redefinition of 'abort' (Bug#12316).
5934 Do not try to redefine the 'abort' function. Instead, redo
5935 the code so that it calls 'emacs_abort' rather than 'abort'.
5936 This removes the need for the NO_ABORT configure-time macro
5937 and makes it easier to change the abort code to do a backtrace.
5938 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5939 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5940 Remove; sysdep.c's emacs_abort now takes its place.
5941 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5942 'abort' changed to use 'emacs_abort'.
5943 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5944 (abort) [!defined abort]: Rename to ...
5945 (emacs_abort): ... new name.
5946 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5947 the place of the old 'abort' in emacs.c.
5948 * w32.c, w32fns.c (abort): Do not #undef.
5949 * w32.c (emacs_abort): Rename from w32_abort.
5951 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5953 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5954 offsets[j].dv, since the y axis of the screen coordinates points
5955 down, while the y axis of the font definition coordinates points
5956 up. This fixes display of Arabic diacritics such as KASRA and
5957 KASRATAN. (Bug#11860)
5959 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>

5962 * alloc.c (test_setjmp, mark_stack):
5963 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5964 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5965 (png_load, my_error_exit, jpeg_load):
5966 * process.c (send_process_trap, send_process):
5967 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5968 The underscored versions are up to 30x faster on some hosts.
5969 Formerly, the code used setjmp+longjmp sometimes and
5970 _setjmp+_longjmp at other times, with no particular reason to
5971 prefer setjmp+longjmp.
5973 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5975 Fix minor problem found by static checking.

6003 * dispextern.h, lisp.h: Reflect above API changes.
6004 * firstfile.c (dummy): Use the address of 'main', whose signature
6005 won't change, instead of the address of 'initialize', whose
6006 signature just changed from int to bool.
6007 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6008 * msdos.c (fatal_error_in_progress): ... from here.
6009 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6011 (redisplay_internal, unwind_redisplay): Simply clear
6012 REDISPLAYING_P when unwinding, instead of saving its previous,
6013 always-false value and then restoring it.
6015 Clean up some extern decls.
6016 Mostly, this hoists extern decls out of .c files and into .h files.
6017 That way, we're more likely to catch errors if the interfaces change.
6018 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6019 declare xg_mark_data.
6020 * dispextern.h (x_frame_parm_handlers):

6040 Remove now-redundant extern decls.
6041 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6042 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6044 * xfaces.c: Remove unnecessary static decls.
6045 * xterm.c (updating_frame): Remove decl of nonexistent object.
6047 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6048 when building globals.h, as the objects that are not built on
6049 this host are not needed to compile C files on this host.
6051 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6053 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6101 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6103 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6104 more than one grapheme cluster passed to the shaper: compute the
6105 offset adjustment values separately for each cluster. (Bug#11860)
6107 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6108 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6109 about implicit conversions from integer to pointer.
6111 2012-09-01 Daniel Colascione <dancol@dancol.org>
6113 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6114 system used too early.
6116 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

6167 window system declarations.
6169 * frame.h: Move common functions here: set_frame_menubar,
6170 x_set_window_size, x_sync, x_get_focus_frame,
6171 x_set_mouse_position, x_set_mouse_pixel_position,
6172 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6199 * lisp.h (mark_ttys): Remove prototype.
6200 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

6233 * lread.c (init_lread): For out-of-tree builds, only add the
6234 source directory's site-lisp dir to the load-path if it exists,

6256 Handle click on close button as quit.
6258 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6259 Add window_closed and button_values. Add void as return value for
6260 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6261 Add process_dialog as new member.
6263 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6265 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

6395 (code_convert_string, code_convert_string_norecord)
6396 (Fset_coding_system_priority):
6397 * fileio.c (Finsert_file_contents):
6398 Use bool for booleans.
6399 * coding.h, lisp.h: Reflect above API changes.
6400 * coding.c: Remove unnecessary static function decls.
6401 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6402 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6403 not a boolean 'int', since callers never look at the return value.
6404 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6405 * coding.h (decoding_buffer_size, encoding_buffer_size)
6406 (emacs_mule_string_char): Remove unused extern decls.
6407 (struct iso_2022_spec, struct coding_system):
6408 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6409 (struct emacs_mule_spec): Remove unused field 'full_support'.
6410 All initializations removed.
6411 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6413 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6415 Fix spare memory change (Bug#12286).
6416 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6417 (valid_lisp_object_p): Likewise.
6419 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6421 * window.c (Fset_window_configuration): Record any window's old
6422 buffer if it's replaced (see Bug#8789). If the new current
6423 buffer doesn't appear in the selected window, go to its old
6426 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6428 Special MEM_TYPE_SPARE to denote reserved memory.
6429 * alloc.c (enum mem_type): New memory type.
6430 (refill_memory_reserve): Use new type for spare memory.
6431 This prevents live_cons_p and live_string_p from incorrect
6432 detection of uninitialized objects from spare memory as live.
6434 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6437 * Makefile.in (.PHONY): versioclean -> versionclean.
6439 Remove unused external symbols.
6440 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6441 * window.c (Qwindow_valid_p, decode_valid_window):
6442 Now static, not extern.
6443 * data.c (Qinterval): Remove; unused.
6444 (syms_of_data): Do not define 'interval'.
6445 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6446 * window.h (decode_valid_window):
6449 * character.c, charset.c, chartab.c: Use bool for booleans.
6450 * character.c (lisp_string_width, string_count_byte8)
6451 (string_escape_byte8):
6452 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6453 (load_charset_map_from_file, map_charset_chars)
6454 (Fdefine_charset_internal, define_charset_internal)
6455 (Fdeclare_equiv_charset, find_charsets_in_text)
6456 (Ffind_charset_region, char_charset, Fiso_charset):
6457 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6458 (sub_char_table_set, sub_char_table_set_range)
6459 (char_table_set_range, optimize_sub_char_table)
6460 (map_sub_char_table):
6461 Use bool for boolean.
6462 * character.c (str_to_unibyte): Omit last boolean argument; it was
6463 always 0. All callers changed.
6464 * character.h, charset.h: Adjust to match previous changes.
6465 * character.h (char_printable_p): Remove decl of nonexistent function.
6466 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6467 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6468 are all boolean, so make them single-bit bitfields.
6470 * lisp.h (ASET): Remove attempt to detect side effects.
6471 It was meant to be temporary and it often doesn't work,
6472 because when IDX has side effects the behavior of IDX==IDX
6473 is undefined. See Stefan Monnier in
6474 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6476 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6478 * lisp.h (functionp): New function (extracted from Ffunctionp).
6479 (FUNCTIONP): Use it.
6480 * eval.c (Ffunctionp): Use it.
6482 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6484 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6485 as that's faster and simpler than static storage. Don't bother
6486 with the g_main_context_query overhead if g_main_context_pending
6487 says no events are pending.
6488 (gfds, gfds_size): Remove these static vars.
6489 (xgselect_initialize): Remove; no longer needed.
6490 All uses and decls removed.
6492 * emacs.c (fatal_error_signal_hook): Remove.
6493 All uses removed. This leftover from old code was always 0.
6495 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6496 * casefiddle.c (casify_object, casify_region):
6497 * casetab.c (set_case_table):
6498 * category.c, category.h (word_boundary_p):
6499 * category.h (CHAR_HAS_CATEGORY):
6500 Use bool for booleans, instead of int.
6502 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6504 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6506 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6508 On assertion failure, print backtrace if available.
6509 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6510 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6511 * Makefile.in (LIB_EXECINFO): New macro.
6514 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6515 * bytecode.c (exec_byte_code):
6516 * callint.c (check_mark, Fcall_interactively):
6517 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6518 (getenv_internal, sync_process_alive, call_process_exited):
6519 * lisp.h (USE_SAFE_ALLOCA):
6520 Use bool for booleans, instead of int.
6521 * lisp.h, process.h: Adjust prototypes to match above changes.
6522 * callint.c (Fcall_interactively): Don't assume the mark's
6523 offset fits in 'int'.
6525 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6527 * buffer.c, buffer.h: Use bool for boolean.
6528 * buffer.c (reset_buffer_local_variables)
6529 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6530 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6531 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6532 (overlay_touches_p, overlay_strings, Foverlay_put)
6533 (report_overlay_modification, call_overlay_mod_hooks):
6534 (mmap_enlarge, mmap_set_vars):
6535 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6536 Use bool for booleans, instead of int.
6537 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6538 since the 1-or-0 return value is always ignored anyway.
6539 (mmap_initialized_p):
6540 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6541 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6543 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6545 * bidi.c: Use bool for boolean.
6546 This is a bit more readable, and makes the text segment of bidi.o
6547 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6548 Presumably it's faster too.
6549 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6551 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6552 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6553 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6554 (bidi_explicit_dir_char, bidi_level_of_next_char)
6555 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6556 Use bool for booleans, instead of int.
6557 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6558 (bidi_unshelve_cache): Adjust decls to match code.
6560 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6562 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6565 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6567 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6568 * atimer.h: Include <stdbool.h>.
6570 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6572 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6573 compile time tests instead of run time tests on systems that do
6575 (FRAME_MAC_P): Remove leftover from deleted code.
6576 * frame.c (syms_of_frame): Remove leftover from deleted code.
6578 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6580 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6582 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6584 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6585 Otherwise, the compiler complains about (A?B:C) where B is void
6586 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6587 (fontset_add): Return void, for FONTSET_ADD.
6589 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6591 * alloc.c: Use bool for booleans.
6592 (gc_in_progress, abort_on_gc)
6593 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6594 (dont_register_blocks) [GC_MALLOC_CHECK]:
6595 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6596 (check_string_bytes, make_specified_string, memory_full)
6597 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6598 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6599 (mark_stack, valid_pointer_p, make_pure_string)
6600 (Fgarbage_collect, survives_gc_p, gc_sweep):
6601 Use bool for booleans, instead of int.
6602 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6603 Remove unused local.
6604 * alloc.c (PURE_POINTER_P):
6605 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6606 * editfns.c (Fformat):
6607 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6609 * fns.c (sweep_weak_table):
6610 * lisp.h (suppress_checking, push_message, survives_gc_p)
6611 (make_pure_string, gc_in_progress, abort_on_gc):
6612 * lread.c (readchar, read1):
6613 * print.c (Fprin1_to_string):
6614 * xdisp.c (push_message):
6615 Use bool for booleans affected directly or indirectly by
6618 Make recently-introduced setters macros.
6619 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6620 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6621 (set_fontset_default, set_fontset_fallback): Rename from their
6622 upper-case counterparts, and make them functions rather than macros.
6623 This is more consistent with the other recently-introduced setters.
6624 These don't need to be inline, since they're local.
6626 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6628 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6629 the loop (Bug#12247).
6631 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6633 * lisp.h (vcopy): Use memcpy rather than our own loop.
6634 This fixes a performance regression introduced by the recent
6635 addition of vcopy. This means 'vcopy' will need to be modified
6636 for a copying collector, but that's OK. Also, tighten the
6637 checking in the assertion.
6639 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6641 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6642 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6643 non-base glyph for the width of the base character, according to
6644 what x_draw_composite_glyph_string_foreground expects.
6645 Generate WADJUST value according to composition_gstring_width's
6646 expectations, to produce correct width of the composed character.
6647 Reverse the sign of the DU offset produced by ScriptPlace.
6649 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6651 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6653 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6655 Avoid direct writes to contents member of struct Lisp_Vector.
6656 * lisp.h (vcopy): New function to copy data into vector.
6657 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6658 * fns.c (Ffillarray): Use ASET.
6659 * keyboard.c (timer_check_2): Use AREF and ASET.
6660 (append_tool_bar_item, Frecent_keys): Use vcopy.
6661 * lread.c (read_vector): Use ASET.
6662 * msdos.c (Frecent_doskeys): Use vcopy.
6663 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6664 (Finternal_merge_in_global_face): Use ASET and vcopy.
6665 * xfont.c (xfont_list_pattern): Likewise.
6667 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6669 * window.c (Fwindow_point): For the selected window always return
6670 the position of its buffer's point.
6671 (Fset_window_point): For the selected window always go in its
6672 buffer to the specified position.
6674 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6676 Setter macros for fontsets.
6677 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6678 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6679 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6682 2012-08-20 Glenn Morris <rgm@gnu.org>
6684 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6685 Don't assume that `ln -f' works.
6687 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6689 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6690 and later about non-assignments with no effect. See discussion at
6691 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6694 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6696 Inline setter functions for Lisp_Objects slots of struct specbinding.
6697 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6700 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6702 * window.c (select_window): Always make selected window's buffer
6705 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6707 Use AREF and ASET for docstrings of category tables.
6708 * category.h (CATEGORY_DOCSTRING): Use AREF.
6709 (SET_CATEGORY_DOCSTRING): Use ASET.
6710 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6712 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6714 Inline setter functions for hash table members.
6715 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6716 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6717 (set_hash_key_and_value, set_hash_index, set_hash_next)
6718 (set_hash_hash): New functions.
6719 * charset.c, fns.c: Adjust users.
6721 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6723 Inline getter and setter functions for per-buffer values.
6724 * buffer.h (per_buffer_default, set_per_buffer_default)
6725 (per_buffer_value, set_per_buffer_value): New functions.
6726 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6727 * buffer.c, data.c: Adjust users.
6729 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6731 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6733 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6735 Rely on <config.h> + <unistd.h> to declare 'environ',
6736 as gnulib does this if the system doesn't.
6737 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6738 Remove declaration. MS-Windows declares it on stdlib.h which is
6739 included by conf_post.h.
6740 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6741 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6742 * vm-limit.c: Include <unistd.h>, for 'environ'.
6744 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6745 (start_of_data): Remove decl; mem-limits.h provides it.
6747 * xdisp.c (handle_invisible_prop): Make it a bit faster
6748 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6750 2012-08-19 Chong Yidong <cyd@gnu.org>
6752 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6755 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6757 * .gdbinit: Use call instead of set when calling a function in the
6760 * data.c (set_internal): Don't use set_blv_found.
6761 (Fkill_local_variable): Likewise.
6763 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6765 * nsfont.m (ns_ascii_average_width): Ensure the string
6766 ascii_printable is initialized with a null-terminated character
6767 array. Otherwise, it can contain undesired extra characters.
6769 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6771 port new setting code to Sun C 5.8 2005/10/13
6772 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6773 Return void, not Lisp_Object. Otherwise, the compiler
6774 complains about (A?B:C) where B is void and C is Lisp_Object
6775 when compiling CHAR_TABLE_SET, due to the recent change to
6776 the API of sub_char_table_set_contents.
6778 2012-08-18 Chong Yidong <cyd@gnu.org>
6780 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6781 for the string case (Bug#3874).
6783 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6785 * buffer.h (BSET): Remove (Bug#12215).
6786 Replace all uses with calls to new setter functions.

6813 (bset_word_wrap, bset_zv_marker):
6814 * category.c (bset_category_table):
6815 * syntax.c (bset_syntax_table):
6816 New setter functions.
6818 * process.h (PSET): Remove (Bug#12215).
6819 Replace all uses with calls to new setter functions.
6820 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.

7718 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7719 checking subscripts; problem introduced with the recent
7720 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7721 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7722 since it's used in non-static inline functions now.
7724 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

7751 (INLINE_HEADER_END): New macros.
7752 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7776 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7777 This how ASET and AREF are supposed to work, and makes
7778 it easier to think about future improvements. See
7779 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7780 * charset.h (set_charset_attr): New function.

8161 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8162 (w32_kbd_patch_key, key_event): Use the codepage returned by
8163 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
8164 (key_event): use uChar.UnicodeChar only if
8165 w32_console_unicode_input is non-zero.
8167 * w32console.c: Include w32heap.h.

8195 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8196 enumeration constants, as PURE and HEAP are too general, and clash
8197 with other headers and sources, such as gmalloc.c and the
8198 MS-Windows system headers. All users changed.
8200 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8202 Revert last save_excursion_save and save_excursion_restore changes.
8203 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8213 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8215 Improve GDB symbol export (Bug#12036).
8216 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8217 arms of an 'if', not using conditional expressions; otherwise GDB
8218 complains about the types in the unevaluated arm when the argument
8219 is an integer literal.
8220 (xgetint): Simplify expression.
8221 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8222 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8223 Zaretskii in <http://bugs.gnu.org/12036#13>.
8224 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8225 needed now that we have gdb_make_enums_visible.
8226 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8227 (enum enum_USE_LSB_TAG):
8228 New enum types, packaging up enums that need to be exported to GDB.

8247 * xfns.c (syms_of_xfns): Likewise.
8249 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8251 Fast save_excursion_save and save_excursion_restore.
8252 * lisp.h (struct Lisp_Excursion): New data type.
8253 (PVEC_EXCURSION): New pseudovector type.
8254 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8255 to deal with it. Adjust comments.

8268 Fix export of symbols to GDB (Bug#12036).
8269 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8270 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8271 emacs.c, as this is a more-suitable home. Had this been done earlier
8272 the fix for 12036 would have avoided some of the problems noted in
8273 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8274 would have been more obvious.
8275 * emacs.c: Do not include <verify.h>; no longer needed.
8276 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8277 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8278 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8279 Remove; now done in lisp.h.
8280 * lisp.h (PUBLISH_TO_GDB): New macro.
8281 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8282 (DATA_SEG_BITS): Use it.
8283 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8284 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8285 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8286 not be usable in #if. This simplifies things.
8288 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8290 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8292 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8294 Simplify export of symbols to GDB (Bug#12036).
8295 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8296 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8297 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8298 Adjust to changes in lisp.h and emacs.c, by using
8299 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8300 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8301 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8302 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8303 instead of gdb_valbits.
8304 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8305 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8306 instead of gdb_array_mark_flag.
8307 (xboolvector): Get size from $->size, not $->header.size.
8308 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8309 (xreload, hook-run, hookpost-run): Remove.
8310 * emacs.c: Include <verify.h>.
8311 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8312 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8314 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8315 (gdb_USE_LSB_TAG): New enum constants.
8316 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8317 Also define these as enum constants, so they're visible to GDB.
8318 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8319 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8320 as constants, so they're visible to GDB.
8321 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8322 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8323 Now enum constants, not macros, so they're visible to GDB.
8324 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8325 more convenient now. All uses changed.
8326 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8327 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8329 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8336 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8337 add argument, tune behavior, and adjust all callers.
8339 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8341 Use typedef for EMACS_INT, EMACS_UINT.
8342 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8343 than macros. This simplifies debugging in the usual case, since
8344 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8345 and it allows expressions involving EMACS_INT casts.
8346 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8348 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8356 that FOCUS-FRAME can be omitted.
8358 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8360 Adjust buffer text indirection counters at the end of Fkill_buffer.
8361 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8362 buffer is definitely dead. This should really fix an issue reported
8363 by Christoph Scholtes again. (Bug#12007).
8364 (init_buffer_once): Initialize indirection counters of
8365 buffer_defaults and buffer_local_symbols (for sanity and safety).
8367 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8369 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8370 and continuation glyphs on tooltip frames, leave them at zero.

8373 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8375 Simplify copy_overlay.
8376 * buffer.c (copy_overlay): Simplify. Use build_marker.

8396 (build_overlay): Add prototype.
8398 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8400 Swap buffer text indirection counters in Fbuffer_swap_text.
8401 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8402 This avoids crash reported by Christoph Scholtes at
8403 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8405 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8407 * nsmenu.m (Popdown_data): New struct.
8408 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8410 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8411 (initWithContentRect): Make imgView and contentView non-static
8412 and autorelease them. Also autorelease img and matrix (Bug#12005).
8413 (dealloc): Remove (Bug#12005).
8415 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8417 Adjust consing_since_gc when objects are explicitly freed.
8418 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
8419 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

8430 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8432 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8433 as it's limited by the amount of memory, not by INT_MAX.
8435 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8437 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8438 in special-event-map. See the discussion at
8439 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
8442 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
8443 info.dwItemData. Fixes crashes on 64-bit Windows.

8497 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8498 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8499 Adjust users accordingly.
8500 * font.h (font_open_by_name): Adjust prototype.

8518 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8519 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8520 'for_each_per_buffer_object_at'.
8521 All uses changed. It's better to use upper-case for macros that
8522 cannot be implemented as functions, to give the reader a clue
8523 that they're special.
8525 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8527 * alloc.c (Fgarbage_collect): Tweak docstring.

8568 * intervals.c (merge_interval_right, merge_interval_left):
8569 Do not zero out this interval if it is absorbed by its children,

8573 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8575 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8576 when invoking (make-bool-vector N t) and N is a positive
8577 multiple of 8 -- the last 8 bits were mistakenly cleared.
8579 Remove some struct layout assumptions in bool vectors.
8580 * alloc.c (bool_header_size): New constant.
8581 (header_size, word_size): Move earlier, as they're now used earlier.

9046 2012-07-11 Glenn Morris <rgm@gnu.org>
9048 * s/gnu-linux.h, s/sol2-6.h: No longer define POSIX,
9049 unused since 2011-01-17 change to systty.h.

9091 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9092 since nothing has defined it on these platforms.
9094 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
9095 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

9106 2012-07-11 John Wiegley <johnw@newartisans.com>
9108 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9109 function attribute, so we only use it if it exists in the
9112 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9114 Avoid call to strlen in fast_c_string_match_ignore_case.

9161 * s/aix4-2.h (unix): Remove; no longer needed.
9163 EMACS_TIME simplification (Bug#11875).
9164 This replaces macros (which typically do not work in GDB)
9165 with functions, typedefs and enums, making the code easier to debug.
9166 The functional style also makes code easier to read and maintain.
9167 * systime.h: Include <sys/time.h> on all hosts, not just if
9168 WINDOWSNT, since 'struct timeval' is needed in general.
9169 (EMACS_TIME): Now a typedef, not a macro.
9170 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9172 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9176 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9177 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9178 which are not functions. All uses rewritten to use:
9179 (make_emacs_time): New function.
9180 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9181 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9182 not functions. All uses rewritten to use the following, respectively:
9183 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9184 (add_emacs_time, sub_emacs_time): New functions.
9185 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9186 * fileio.c (Fcopy_file):
9187 * xterm.c (XTflash): Get the current time closer to when it's used.
9188 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9196 * gtkutil.c (get_utf8_string):
9198 * nsmenu.m (ns_update_menubar):
9199 * regex.c (regerror):

9201 * fileio.c (Fsubstitute_in_file_name):
9202 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9203 (menu_separator_name_p):
9204 * nsmenu.m (ns_update_menubar):
9205 Prefer memcmp to strncmp when either will do.
9206 * nsterm.m: Include <ftoastr.h>.
9208 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9209 Prefer snprintf to strncpy.
9210 * nsterm.m (ns_term_init):
9211 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9212 * nsterm.m (ns_term_init):
9213 Avoid the need for strncpy, by using build_string or
9214 make_unibyte_string directly. Use dtoastr, not snprintf.
9215 * process.c (Fmake_network_process): Diagnose service names that
9216 are too long, rather than silently truncating them or creating
9217 non-null-terminated names.
9218 (Fnetwork_interface_info): Likewise, for interface names.
9219 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9220 Prefer sprintf to strncat.
9221 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9222 Prefer vsnprintf to vsprintf + strncpy.
9224 2012-07-10 Glenn Morris <rgm@gnu.org>
9226 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9227 Clarify fallback case.
9229 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9231 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9232 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9233 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9234 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9235 where argument type is known to be a Lisp_Cons.
9237 2012-07-10 Tom Tromey <tromey@redhat.com>
9239 * bytecode.c (BYTE_CODE_THREADED): New macro.
9240 (BYTE_CODES): New macro. Replaces all old byte-code defines.

9247 Optimize pure C strings initialization.
9248 * lisp.h (make_pure_string): Fix prototype.
9249 (build_pure_c_string): New function, defined as static inline. This
9250 provides a better opportunity to optimize away calls to strlen when
9251 the function is called with compile-time constant argument.
9252 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9253 argument, adjust users accordingly. Use build_pure_c_string where
9255 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9256 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9257 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9259 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9261 Avoid calls to strlen in miscellaneous functions.
9262 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9263 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9264 * lread.c (openp): Likewise.
9266 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9268 Avoid calls to strlen in path processing functions.
9269 * fileio.c (file_name_as_directory): Add comment. Change to add
9270 srclen argument and return the length of result. Adjust users
9272 (directory_file_name): Fix comment. Change to add srclen argument,
9273 swap 1st and 2nd arguments to obey the common convention.
9274 Adjust users accordingly.
9275 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9277 2012-07-10 Glenn Morris <rgm@gnu.org>
9279 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9282 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9283 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9284 * s/gnu.h (DATA_START): Move definitions to configure.
9286 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9287 We include usg5-4-common.h, which defines them both.
9289 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9290 O_RDONLY already includes it).
9292 Stop ns builds setting the EMACSLOADPATH environment variable.
9293 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9294 Now it does not set EMACSLOADPATH, just returns the load-path string.
9295 * nsterm.h: Update accordingly.
9296 * lread.c [HAVE_NS]: Include nsterm.h.
9297 (init_lread) [HAVE_NS]: Use ns_load_path.
9298 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9300 2012-07-09 Glenn Morris <rgm@gnu.org>
9302 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9303 since the included bsd-common.h does so.
9305 Stop ns builds setting the EMACSPATH environment variable.
9306 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9307 (ns_init_paths): Do not set EMACSPATH.
9308 * nsterm.h (ns_exec_path): Add it.
9309 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9312 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9314 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9316 * process.c (wait_reading_process_output): 'waitchannels' was unset
9317 when read_kbd || !NILP (wait_for_cell); fix this.
9319 Add GCC-style 'const' attribute to functions that can use it.
9320 * character.h (char_resolve_modifier_mask):
9321 * keyboard.h (make_ctrl_char):
9322 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9323 (init_character_once, next_almost_prime, init_fns, init_image)
9324 (flush_pending_output, init_sound):
9325 * mem-limits.h (start_of_data):
9326 * menu.h (finish_menu_items):
9327 Add ATTRIBUTE_CONST.

9329 Declare the dummy function with ATTRIBUTE_CONST.
9330 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9331 Add decls with ATTRIBUTE_CONST.
9333 Minor improvements to make_formatted_string.
9334 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9335 where int is good enough, as vsprintf returns an int.
9336 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9338 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9340 Use make_formatted_string to avoid double length calculation.
9341 * lisp.h (make_formatted_string): New prototype.
9342 * alloc.c (make_formatted_string): New function.
9343 * buffer.c (Fgenerate_new_buffer_name): Use it.
9344 * dbusbind.c (syms_of_dbusbind): Likewise.
9345 * editfns.c (Fcurrent_time_zone): Likewise.
9346 * filelock.c (get_boot_time): Likewise.
9347 * frame.c (make_terminal_frame, set_term_frame_name)
9348 (x_report_frame_params): Likewise.
9349 * image.c (gs_load): Likewise.
9350 * minibuf.c (get_minibuffer): Likewise.
9351 * msdos.c (dos_set_window_size): Likewise.
9352 * process.c (make_process): Likewise.

9365 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9367 Move marker debugging code under MARKER_DEBUG.
9368 * marker.c (MARKER_DEBUG): Move marker debugging code under
9369 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9370 for bootstrap with --enable-checking (~3x slowdown reported
9371 by Juanma Barranquero <lekktu@gmail.com>).
9372 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9374 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9376 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9377 See <http://bugs.gnu.org/11825#29>.
9379 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9381 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9382 has no font, use the frame's font. (Bug#11813)
9383 (display_line): Add commentary about displaying truncation glyphs
9385 (produce_special_glyphs): Move here from term.c.
9387 * term.c (produce_special_glyphs): Move to xdisp.c.
9389 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9392 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9394 * xdisp.c (display_line): Avoid warning about implicit declaration
9397 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9399 * lisp.h: Remove empty conditional.
9401 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9403 * lread.c (load_path_check): Now static.
9405 Fix some minor --with-ns problems found by static checking.
9406 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9407 (x_set_font) [!HAVE_X_WINDOWS]:
9408 * image.c (xpm_load_image) [HAVE_NS]:
9409 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9410 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9411 Remove unused local.
9412 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9413 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9414 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9415 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9416 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9417 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9418 Fix pointer signedness problem.
9419 * xfaces.c (FRAME_X_FONT_TABLE):
9420 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9422 2012-07-07 Glenn Morris <rgm@gnu.org>
9424 * lread.c (load_path_check): New function, split from init_lread.
9425 (init_lread): Reorganize. Motivation:
9426 If EMACSLOADPATH is set, check/warn about that rather than the
9427 defaults, which we are not going to use. Hence we can remove
9428 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9429 Don't warn if site-lisp directories are missing.
9430 If not installed, start from a blank load-path, since
9431 PATH_LOADSEARCH refers to the eventual installation directories.
9433 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9435 Support truncation and continuation glyphs on GUI frames, when
9436 fringes are disabled. (Bug#11832)
9437 * xdisp.c (init_iterator): Get dimensions of truncation and
9438 continuation glyphs even if on GUI frames.
9439 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9440 or both, are absent.
9441 (start_display, move_it_in_display_line_to): Handle the case of a
9442 GUI frame without a fringe to display continuation or truncation
9444 (insert_left_trunc_glyphs): Support GUI frames: make sure
9445 truncation glyphs overwrite enough glyphs from the current line to
9446 have sufficient space in pixels.
9447 (display_line): Support truncation and continuation glyphs on GUI
9448 frames. If some spare pixels are left on the line after inserting
9449 the truncation glyphs, fill that space with a stretch glyph of a
9450 suitably computed width.
9452 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9453 produce_glyphs, to support GUI sessions.
9455 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9457 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9459 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9461 Do not require float-time's arg to fit in time_t (Bug#11825).
9462 This works better on hosts where time_t is unsigned, and where
9463 float-time is applied to the (negative) difference between two times.
9464 * editfns.c (decode_time_components): Last arg is now double *,
9465 not int *, and means to store all the result as a double, without
9466 worrying about whether the seconds part fits in time_t.
9467 All callers changed.
9468 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9469 All callers changed.
9470 (Ffloat_time): Do not fail merely because the specified time falls
9471 outside of time_t range.
9473 2012-07-07 Glenn Morris <rgm@gnu.org>
9475 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9476 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9477 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9479 2012-07-07 Juanma Barranquero <lekktu@gmail.com>

9490 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9491 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.

9497 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9499 * xfns.c (Fx_change_window_property): Doc fix.
9500 * w32fns.c (Fx_change_window_property): Doc fix.
9502 * w32fns.c (Fx_window_property): Accept the same arguments as the
9503 X Windows version. Doc fix.
9504 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9506 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9507 Eli Zaretskii <eliz@gnu.org>
9509 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

9511 Obsolete settings removed.
9513 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9515 * process.c: Avoid unnecessary calls to gettime.
9516 (wait_reading_process_output): Don't get the time of day
9517 when gobbling data immediately and not waiting, as there's no need
9518 for it in that case. This removes a FIXME.
9520 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9522 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9523 is defined (Bug#11768).

9527 Fix marker debugging code.
9528 * marker.c (byte_char_debug_check): Do not perform the check
9529 if buffer is not multibyte.
9530 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9531 Call byte_char_debug_check with correct arguments.
9533 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9535 Compile marker debugging code only if ENABLE_CHECKING is defined.
9536 * marker.c (byte_char_debug_check, count_markers):
9537 Use only if ENABLE_CHECKING is defined.
9538 (byte_debug_flag): Remove.
9539 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9540 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9542 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9544 Avoid code repetition in marker-related functions.
9545 * marker.c (attach_marker): New function.

9548 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9549 Consistently rename charno to charpos.
9550 (marker_position): Add eassert.
9551 (marker_byte_position): Convert to eassert.
9553 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9563 * lisp.h (build_marker): New prototype.
9564 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9565 * composite.c (autocmp_chars): Likewise.
9566 * editfns.c (buildmark): Remove.
9567 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9568 (save_restriction_save): Use build_marker.
9569 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9570 * window.c (save_window_save): Likewise.
9572 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9577 (delete_all_overlays, Fdelete_overlay): Use it.
9578 * minibuf.c (get_minibuffer): Fix comment.
9580 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9582 Port to OpenBSD 5.1 amd64.
9583 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9584 This is needed for OpenBSD, and should be harmless on all BSD systems.
9585 Also, include <sys/sysctl.h>, as it should be available on all
9586 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9587 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9588 use p_pid member, not kp_proc.pid.
9590 2012-07-06 Glenn Morris <rgm@gnu.org>
9592 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9594 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9596 More xmalloc and related cleanup.
9597 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9605 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9607 Omit needless casts involving void * pointers and allocation.
9608 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9609 as the former is more robust if P's type is changed.
9610 Prefer xzalloc to xmalloc + memset 0.
9611 Simplify malloc-or-realloc to realloc.
9612 Don't worry about xmalloc returning a null pointer.
9613 Prefer xstrdup to xmalloc + strcpy.
9614 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9616 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9617 alloca of a constant.
9619 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9621 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9622 hscroll is larger than the line width. Fixes long and futile
9623 looping inside extend_face_to_end_of_line (on a TTY) producing
9624 glyphs that are not needed and thrown away.
9626 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9628 * marker.c (set_marker_restricted_both): Simplify by using
9631 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9640 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9641 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9642 followed by gtk_box_set_homogeneous (Bug#11768).
9643 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9644 (update_theme_scrollbar_width, xg_create_scroll_bar):
9645 Use gtk_scrollbar_new (Bug#11768).
9646 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9647 (is_box_type): New function (Bug#11768).
9648 (xg_tool_item_stale_p): Call is_box_type.
9649 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9650 with default display (Bug#11768).

9654 * xdisp.c (window_hscroll_limited): New function.
9655 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9656 coordinates when window's hscroll is set to insanely large
9659 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9661 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9720 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9722 * fileio.c (time_error_value): Check the right error number.
9723 Problem reported by Troels Nielsen in
9724 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9728 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9729 This should be fixed in a better way; see Eli Zaretskii in
9730 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9731 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9733 * fileio.c (time_error_value): Rename from special_mtime.
9734 The old name's problems were noted by Eli Zaretskii in
9735 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9737 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9738 This variable's comment says Emacs needs at least one GDB-visible
9739 symbol of type enum pvec_type, to work around GDB problems.
9740 The symbol's value doesn't matter.
9742 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9743 that causes compilation to fail on pre-C99 compilers.
9745 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9747 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9748 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9750 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9752 * buffer.c (init_buffer_once): Fix initialization of
9753 headers for buffer_defaults and buffer_local_symbols.
9754 Reported by Juanma Barranquero <lekktu@gmail.com>.

9758 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9759 * lisp.h (enum pvec_type): Use fewer bits.
9760 (PSEUDOVECTOR_SIZE_BITS): New constant.
9761 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9762 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9763 change in pvec_type.
9764 (PSEUDOVECTOR_TYPEP): New macro.

9770 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9771 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9772 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9773 abusing vector->header.next.nbytes.
9774 (live_vector_p): Use PVEC_TYPE.
9775 (mark_object): Adapt code to extract pvectype. Use switch.
9777 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9779 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9780 Tighten new eassert a bit.
9782 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9784 Fix compilation with --enable-gcc-warnings and -O1
9786 * doprnt.c (doprnt): Change type of tem to int, initialize
9787 to avoid compiler warning. Add eassert.
9788 * search.c (simple_search): Initialize match_byte to avoid
9789 compiler warning. Add eassert.
9791 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9793 Avoid weird behavior with large horizontal scrolls.
9794 Without this change, for example, large hscroll values would
9795 mess up Emacs's display on Fedora 15 x86, presumably due to
9796 overflows in int calculations in the display code.
9797 Also, if buffers had long lines, Emacs would freeze.
9798 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9799 (set_window_hscroll): New function, containing the old guts of
9800 Fset_window_hscroll. Return the clipped value.
9801 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9802 This avoids the need to check against PTRDIFF_MAX.
9804 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9806 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9810 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9812 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9813 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9814 since GCC 4.4.6 issues a bogus warning for them.
9816 Fix bugs in file timestamp newness comparisons.
9817 * fileio.c (Ffile_newer_than_file_p):
9818 * lread.c (Fload): Use full timestamp resolution of files,
9819 not just the 1-second resolution, so that files that are only
9820 slightly newer still count as newer.
9821 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9822 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9824 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9826 * fileio.c: Improve handling of file time marker. (Bug#11852)
9827 (special_mtime): New function.
9828 (Finsert_file_contents, Fverify_visited_file_modtime):
9829 Use it to set special mtime values consistently.
9831 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9833 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9834 marker for non-existing file. (Bug#11852)
9836 2012-07-03 Glenn Morris <rgm@gnu.org>
9838 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9839 and did not make it into globals.h).
9841 2012-07-03 Tom Tromey <tromey@redhat.com>
9843 * window.c (Fset_window_margins, Fset_window_fringes)

9877 * xterm.h: Remove EXFUN.
9879 2012-07-03 Glenn Morris <rgm@gnu.org>
9881 * lisp.h (Frandom): Make it visible to C.
9882 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9883 buffer for invisible buffers. (Bug#1229)

9887 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9888 values which aren't power of 2.
9889 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9890 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9893 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9895 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

9901 * alloc.c (allocate_vector_block): Remove redundant
9902 calls to mallopt if DOUG_LEA_MALLOC is defined.
9903 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9904 avoid calls to mallopt if zero_vector is returned.
9906 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9908 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9909 is enabled, avoid dereferencing NULL current_sblock if
9912 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9914 Cleanup basic buffer management.
9915 * buffer.h (struct buffer): Change layout to use generic vector
9916 marking code. Fix some comments. Change type of 'clip_changed'
9917 to bitfield. Remove unused #ifndef old.
9918 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

9928 Lisp area of struct buffer.
9929 (mark_object): Use it. Adjust marking of misc objects
9930 and related comments.
9932 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9934 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9935 wrapper that is not needed because the wrapped code is a no-op (zero
9936 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9937 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9939 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9941 * alloc.c (mark_buffer): Simplify. Remove prototype.
9942 (mark_object): Add comment. Reorganize marking of vector-like
9943 objects. Use CHECK_LIVE for all vector-like objects except buffers
9944 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9945 Avoid redundant calls to mark_vectorlike for bool vectors.
9947 2012-06-30 Glenn Morris <rgm@gnu.org>
9949 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9951 * epaths.in (PATH_SITELOADSEARCH): New.
9952 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9953 This is rather than relying on --enable-locallisppath elements
9954 having "site-lisp" in their names. (Bug#10208#25, 11658)
9956 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9958 * w32proc.c (sys_select): Accept and ignore one more argument.
9960 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9962 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9963 (pselect) [!MS_DOS]: Redirect to sys_select.
9965 * sysdep.c: Don't include dos.h and dosfns.h.
9967 * process.c (sys_select):
9968 * msdos.c (sys_select): Accept one more argument and ignore it.
9970 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9971 adapt data types and code to that.
9974 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9975 which clashes with the gnulib function of the same name.
9977 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9979 * font.c (font_style_to_value, font_style_symbolic)

9983 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9985 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9988 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9990 * xdisp.c (try_window_id): Undo last change.
9992 * w32.c (getwd): Adjust commentary about startup_dir.
9993 (init_environment): Always call sys_access, even in non-MSVC
9994 builds. Don't chdir to the directory of the Emacs executable.
9995 This undoes code from 1997 which was justified by the need to
9996 "avoid conflicts when removing and renaming directories". But its
9997 downside was that every relative file name was being interpreted
9998 relative to the directory of the Emacs executable, which can never
9999 be TRT. In particular, it broke sys_access when called with
10000 relative file names.
10001 (sys_access): Map GetLastError to errno.
10003 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10009 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10012 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

10039 * window.c (HSCROLL_MAX): New macro.
10040 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10041 overflow when requested scroll falls outside ptrdiff_t range.
10043 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10045 * window.h (struct window): Change type of 'hscroll',
10046 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10047 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10048 Adjust users accordingly.
10049 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10050 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10051 from EMACS_INT to ptrdiff_t.

10127 * alloc.c (allocate_string): Omit intervals initialization.
10128 * alloc.c (make_uninit_multibyte_string): Initialize intervals

10154 when building with Clang.

10185 * alloc.c: Remove build_string.

10193 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10195 Use sprintf return value instead of invoking strlen on result.
10196 In the old days this wasn't portable, since some sprintf
10197 implementations returned char *. But they died out years ago and
10198 Emacs already assumes sprintf returns int.
10199 Similarly for float_to_string.
10200 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10206 * xdisp.c (message_dolog):
10207 * xfns.c (syms_of_xfns):
10208 Use sprintf or float_to_string result to avoid need to call strlen.
10209 * data.c (Fnumber_to_string):
10210 Use make_unibyte_string, since the string must be ASCII.
10211 * lisp.h, print.c (float_to_string): Now returns int length.
10212 * term.c (produce_glyphless_glyph):
10213 Use sprintf result rather than recomputing it.
10215 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10216 * Makefile.in (ALL_CFLAGS):
10217 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10222 * dispextern.h (xstrcasecmp): Define to library function
10223 strcasecmp if available.

10242 sprintf already null-terminates its output.
10244 * xfns.c (x_window): Remove redundant cast.
10246 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10248 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10249 `const char *' to `char *' to avoid compiler warning.
10251 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10253 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10254 instead of truncating it to 63 (admittedly a generous limit).
10256 * process.c: Fix spelling and caps in comments.
10258 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

10314 * keyboard.c (kbd_buffer_get_event):
10315 * process.c (Faccept_process_output):
10316 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10317 This improves on the previous patch, which introduced a bug
10318 when time_t is unsigned and as wide as intmax_t.
10319 See <http://bugs.gnu.org/9000#51>.
10321 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10349 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10350 language ID in the event parameters.
10352 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10353 event.code, not the obscure "character set ID".
10355 2012-06-23 Chong Yidong <cyd@gnu.org>
10357 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10371 in the logic of incrementing and decrementing the value of
10372 use_relocatable_buffers.

10386 Support higher-resolution time stamps (Bug#9000).
10387 The time stamps are only nanosecond-resolution at the C level,
10388 since that's the best that any real-world system supports now.
10389 But they are picosecond-resolution at the Lisp level, as that's
10390 easy, and leaves room for future OS improvements.
10392 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10395 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10396 Don't get current time unless it's needed.
10398 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10399 now provides it if it's absent.
10400 (start_atimer): Port to higher-res time stamps.
10401 Check for time stamp overflow. Don't get current time more
10402 often than is needed.
10404 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10405 Include systime.h, not time.h.
10406 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10408 * dired.c: Include stat-time.h.
10409 (Ffile-attributes): File times now have higher resolution.
10411 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10412 (struct image): Timestamp now has higher resolution.
10414 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10415 has at least microseconds now. All uses removed.
10416 (update_frame, update_single_window, update_window, update_frame_1)
10417 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10418 (duration_to_sec_usec): Remove; no longer needed.
10420 * editfns.c (time_overflow): Now extern.
10421 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10422 (float-time, Fformat_time_string, Fcurrent_time_string)
10423 (Fcurrent_time_zone): Accept and generate higher-resolution

10427 (make_time): Now static.
10428 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10429 Report an error if the time is invalid, rather than having the caller
10432 * fileio.c: Include <stat-time.h>
10433 (Fcopy_file): Copy higher-resolution time stamps.
10434 Prefer to set the time stamp via a file descriptor if that works.

10445 (lookup_image): Port to higer-resolution time stamps.
10447 * keyboard.c (start_polling, bind_polling_period):
10448 Check for time stamp overflow.
10449 (read_char, kbd_buffer_get_event, timer_start_idle)
10450 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10451 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10452 Port to higher-resolution time stamps. Do not assume time_t is signed.
10453 (decode_timer): New function. Timers are now vectors of length 9,
10454 not 8, to accommodate the picosecond component.
10455 (timer_check_2): Use it.
10457 * nsterm.m (select_timeout, timeval_subtract): Remove.
10458 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10459 as they're a bit more accurate and handle overflow better.
10460 (ns_select): Change prototype to be compatible with pselect.
10461 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10462 * nsterm.h (ns_select): Adjust prototype.
10464 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

10479 (wait_reading_process_output):
10480 Port to ns-resolution time stamps.
10481 (Faccept_process_output, wait_reading_process_output):
10482 Check for time stamp overflow. Do not assume time_t is signed.
10483 (select_wrapper): Remove; we now use pselect.
10484 (Fprocess_attributes): Now generates ns-resolution time stamps.
10486 * sysdep.c: Include utimens.h. Don't include utime.h
10487 or worry about struct utimbuf; gnulib does that for us now.
10488 (gettimeofday): Remove; gnulib provides a substitute.
10489 (make_timeval): New function.
10490 (set_file_times): Now sets ns-resolution time stamps.
10491 New arg FD; all uses changed.

10494 Now returns ns-resolution time stamp. All uses changed.
10495 Check for time stamp overflow.
10497 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10498 provides a substitute now.
10500 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10501 since it guarantees struct timespec.
10502 (EMACS_TIME): Now struct timespec, so that we can support
10503 ns-resolution time stamps.
10504 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10505 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10506 (EMACS_USECS): Remove.
10507 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10508 so multiply the arg by 1000 before storing it.
10509 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10511 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10518 (make_timeval, make_lisp_time, decode_time_components): New decls.
10519 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10520 that it mishandled time_t overflow. You can't compare by subtracting!
10521 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10522 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10524 * term.c: Include <sys/time.h>.

10529 in the undo buffer.
10530 (Fprimitive_undo): Use them when restoring time stamps.
10532 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10533 (w32_get_internal_run_time):
10534 Port to higher-resolution Emacs time stamps.
10535 (ltime): Now accepts single 64-bit integer, as that's more convenient
10538 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10540 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10541 for compatibility with pselect. Support ns-resolution time stamps.
10543 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10545 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10546 Check for time stamp overflow, and support ns-resolution time stamps.
10548 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10549 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10550 (timeval_subtract): Remove; no longer needed.
10551 (XTflash, XTring_bell, x_wait_for_event):
10552 Port to ns-resolution time stamps. Don't assume time_t is signed.

10558 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10560 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10561 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10562 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10563 staticidx goes up to 1597 out of 1600 = 0x640.)
10565 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10567 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10568 Otherwise, the umask might be mistakenly 0 while handling input signals.
10570 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10572 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10578 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10579 access to `contents' member of Lisp_Vector objects with AREF and ASET
10582 2012-06-19 Chong Yidong <cyd@gnu.org>
10584 * frame.c (delete_frame): When selecting a frame on a different
10585 text terminal, do not alter the terminal's top-frame.

10589 (unwind_format_mode_line): Restore them.
10590 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10592 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10596 * term.c (Ftty_top_frame): New function.
10598 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10601 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10602 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10603 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10604 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10605 (METER_1, METER_2): Simplify.
10607 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10609 * data.c (Fdefalias): Return `symbol' (bug#11686).
10611 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10613 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10614 gets killed during executing of this function (Bug#11665).
10615 Try to always return Qt when the buffer has been actually killed.
10616 (Vkill_buffer_query_functions): In doc-string say that functions
10617 run by this hook should not change the current buffer.
10619 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10621 Fix recently-introduced process.c problems found by static checking.

10639 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10641 * lisp.h (eassert): Assume C89 or later.
10642 This removes the need for CHECK.
10643 (CHECK): Remove. Its comments about always evaluating its
10644 argument were confusing, as 'eassert' typically does not evaluate
10647 * coding.c (produce_chars): Use ptrdiff_t, not int.
10649 * xterm.c (x_draw_underwave): Check for integer overflow.
10650 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10836 as the union type is for debugging, not for production.
10837 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10838 Use an inline function on all platforms when using the union type,
10839 since this is simpler and 'static inline' can be used portably
10841 (LISP_INITIALLY_ZERO): New macro.

10981 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10983 * doprnt.c (doprnt): Truncate multibyte char correctly.
10984 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10985 would mishandle a string argument "Xc" if X was a multibyte
10986 character of length 2: it would truncate after X's first byte
10987 rather than including all of X.
10989 2012-06-06 Chong Yidong <cyd@gnu.org>
10991 * buffer.c (word_wrap): Doc fix.

11038 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11040 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11041 Convert pctcpu and pctmem to Lisp float properly.
11042 Let the compiler fold better, as 100.0/0x8000 is exact.
11044 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11046 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11056 bitfields where appropriate, remove unused fields.
11057 * window.h (struct window): Remove unused 'last_mark_x' and
11058 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11059 change its type from Lisp_Object to bitfield.
11060 Change type of 'force_start', 'optional_new_start',
11061 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11062 fields from Lisp_Object to bitfield. Adjust users accordingly.
11064 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11066 Pacify gcc -Wdouble-precision when using Xaw.
11067 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11068 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11069 Use 'float' consistently, rather than 'float' in most places
11070 and 'double' in a couple of places.
11072 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11074 * xdisp.c (handle_stop): Detect whether we have overlay strings
11075 loaded by testing it->current.overlay_string_index to be
11076 non-negative, instead of checking whether n_overlay_strings is
11077 positive. (Bug#11587)
11079 2012-05-31 Chong Yidong <cyd@gnu.org>
11081 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11087 * search.c (search_buffer): Remove calls to
11088 r_alloc_inhibit_buffer_relocation, as it is now called by
11089 maybe_unify_char, which was the cause of relocation of buffer text
11092 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11094 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11095 for the duration of call to load_charset, to avoid problems with
11096 callers of maybe_unify_char that access buffer text through C
11099 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11100 decrement the inhibition flag, instead of just setting or
11103 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11105 Remove obsolete '#define static' cruft.
11106 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11107 This #undef was "temporary" in 2000; it is no longer needed
11108 now that '#define static' has gone away.
11109 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11110 (gray_bitmap_bits): Remove; no longer needed.
11111 All uses replaced with definiens.

11119 Define only on platforms that need it.
11120 * emacs.c: Include <sys/gmon.h> when profiling.
11121 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11122 (__executable_start): Remove decl, since lisp.h does it now.
11123 (safe_bcopy): Remove decl; no longer has that name.
11124 (main): Coalesce #if into single bit of code, for simplicity.
11125 Cast pointers to uintptr_t, since standard libraries want integers
11127 * lisp.h (__executable_start): New decl.
11129 2012-05-31 Glenn Morris <rgm@gnu.org>
11131 * image.c (Fimagemagick_types): Doc fix.

11154 Do not create empty overlays with the evaporate property (Bug#9642).
11155 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11156 Bug#9642, but explicitly check that the buffer the overlay would
11157 be moved to is live and rearrange lines to make sure that errors
11158 will not put the overlay in an inconsistent state.
11159 (Fdelete_overlay): Cosmetics.
11161 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11163 * w32term.c (my_bring_window_to_top): New function.
11164 (x_raise_frame): Use handle returned by DeferWindowPos, which
11165 could be different from the original one.

11181 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11183 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11197 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11198 Only r_alloc_inhibit_buffer_relocation needed to be added;
11199 the others were already declared.
11201 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11202 before checking whether it's out of range. Put the check inside
11204 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11206 2012-05-27 Ken Brown <kbrown@cornell.edu>

11218 they are now on lisp.h.
11220 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11222 * search.c (search_buffer): Use it to inhibit relocation of buffer
11223 text while re_search_2 is doing its job, because re_search_2 is
11224 passed C pointers to buffer text. (Bug#11519)
11226 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11227 Update value to 24.
11229 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11230 state after an additional call to move_it_in_display_line_to, keep
11231 the values of it->max_ascent and it->max_descent found for the
11233 (pos_visible_p): Revert the comparison against bottom_y to what it
11234 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11237 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11239 Fix coding-related core dumps with gcc -ftrapv.
11240 The code was computing A - B, where A and B are pointers, and B is
11241 random garbage. This can lead to core dumps on platforms that
11242 have special pointer registers, and it also leads to core dumps on
11243 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11244 A - B only when B is initialized properly.
11245 * coding.c (coding_set_source, coding_set_destination): Return void.
11246 (coding_change_source, coding_change_destinations): New functions,
11247 with the old behaviors of coding_set_source and coding_set_destination.

11258 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11260 * w32console.c: Include window.h.
11261 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11263 (initialize_w32_display): Initialize mouse-highlight data.
11265 * w32inevt.c: Include termchar.h and window.h.
11266 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11267 moves, call note_mouse_highlight. If help_echo changed, call
11268 gen_help_event to produce help-echo message in the echo area.
11269 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11272 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11274 * lread.c (read1): Simplify slightly to avoid an overflow warning
11275 with GCC 4.7.0 on x86-64.
11277 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11279 * bidi.c (bidi_mirror_char): Revert last change: an int is
11280 definitely wide enough here.

11292 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11294 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11295 (allocate_pseudovector):
11296 Use int, not EMACS_INT, where int is wide enough.
11297 (inhibit_garbage_collection, Fgarbage_collect):
11298 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11299 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11300 int might not be wide enough.

11318 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11319 (validate_region): Omit unnecessary test for b <= e,
11320 since that's guaranteed by the previous test.
11321 (adjust_overlays_for_delete): Avoid pos + length overflow.
11322 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11323 (report_overlay_modification):
11324 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11325 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11326 Omit pointer cast, which isn't needed anyway, and doesn't work
11327 after the EMACS_INT -> ptrdiff_t change.
11328 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11329 * buffer.h: Adjust decls to match defn changes elsewhere.
11330 (struct buffer_text, struct buffer):
11331 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11332 Use EMACS_INT, not int, where int might not be wide enough.
11333 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11334 not int, to avoid needless 32-bit limit on 64-bit hosts.
11335 (exec_byte_code): Use tighter memory-full test, one that checks
11336 for alloca overflow. Don't compute the address of the object just
11337 before an array, as that's not portable. Use EMACS_INT, not
11338 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11339 * callint.c (Fcall_interactively):
11340 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11341 * callproc.c (call_process_kill, Fcall_process):
11342 Don't assume pid_t fits into an Emacs fixnum.

11352 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11353 (casify_object): Avoid integer overflow when overallocating buffer.
11354 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11355 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11356 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11357 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11358 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

11362 For CCL_MapSingle, check that content and value are in int range.

11364 Check that Vcode_version_map_vector is a vector.
11365 (resolve_symbol_ccl_program): Check that vector header is in range.
11366 Always copy the vector, so that we can check its contents reliably
11367 now rather than having to recheck each instruction as it's being
11368 executed. Check that vector words fit in 'int'.
11369 (ccl_get_compiled_code, Fregister_ccl_program)

11376 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

11395 Remove now-unnecessary CHECK_NATNUMs.
11396 (Fdefine_charset_internal): Check ranges here, more carefully.
11397 Don't rely on undefined behavior with signed left shift overflow.
11398 Don't assume unsigned int fits into fixnum, or that fixnum fits
11399 into unsigned int. Don't require max_code to be a valid fixnum;
11400 that's not true for gb10830 4-byte on a 32-bit host. Allow
11401 invalid_code to be a cons, for the same reason. Require code_offset
11402 to be a character. Avoid int overflow if max_char is close
11404 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11405 this is intended anyway and avoids some undefined behavior.
11406 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11407 INDEX_TO_CODE_POINT, as that's what it expects.
11408 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11409 * charset.h (DECODE_CHAR): Return int, not unsigned;
11410 this is what was intended anyway, and it avoids undefined behavior.
11411 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11412 integer-overflow issues.
11413 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11414 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11415 where the argument is EMACS_INT, and this behavior is not intended.
11416 * chartab.c (Fmake_char_table, Fset_char_table_range)
11417 (uniprop_get_decoder, uniprop_get_encoder):
11418 Don't assume fixnum fits in int.
11419 * cmds.c (move_point): New function, that does the gist of
11420 Fforward_char and Fbackward_char, but does so while checking
11421 for integer overflow more accurately.
11422 (Fforward_char, Fbackward_char): Use it.
11423 (Fforward_line, Fend_of_line, internal_self_insert)
11424 (internal_self_insert):
11425 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12072 * xterm.c (x_x_to_emacs_modifiers):
12073 Don't assume EMACS_INT overflows nicely into int.
12074 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12075 may come from Lisp.

12084 2012-05-25 Glenn Morris <rgm@gnu.org>
12086 * lisp.mk (lisp): Update for more files being compiled now.
12088 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12090 * lread.c: Remove `read_pure' which makes no difference.
12091 (read_pure): Remove var.
12092 (unreadpure): Remove function.
12093 (readevalloop): Don't call read_list with -1 flag.
12094 (read1, read_vector): Don't test read_pure any more.
12095 (read_list): Simplify.

12106 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12108 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12111 This directory predates autoconf and is no longer needed nowadays.
12112 Move its few remaining bits of functionality to where they're needed.
12113 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12114 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

12118 * lisp.h (USE_LSB_TAG):
12119 * mem-limits.h (EXCEEDS_LISP_PTR):
12120 Use VAL_MAX, not VALBITS, in #if.
12121 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12122 (EMACS_UINT): Define unconditionally now.
12123 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12124 (BITS_PER_EMACS_INT): New constants, replacing
12125 what used to be in config.h, but not useful in #if.
12126 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12127 define them any more.
12128 (VAL_MAX): New macro.
12130 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12131 BITS_PER_EMACS_INT, in #if.
12132 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12133 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12134 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12135 * s/ms-w32.h (DATA_START):
12136 Move here from removed file m/intel386.h.
12137 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12138 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12140 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12142 Assume C89 or later.
12143 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12144 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12146 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

12163 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12165 2012-05-19 Ken Brown <kbrown@cornell.edu>
12167 * xfns.c (x_in_use): Remove `static' qualifier.
12168 * xterm.h (x_in_use): Declare.
12169 * xgselect.c: Include xterm.h.
12170 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12171 and `display_arg' (bug#9754).
12173 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12175 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12177 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12178 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12180 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12182 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12184 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12185 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12187 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12188 reference to image_cache->refcount.
12189 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12191 2012-05-17 Juri Linkov <juri@jurta.org>
12193 * search.c (Fword_search_regexp, Fword_search_backward)
12194 (Fword_search_forward, Fword_search_backward_lax)
12195 (Fword_search_forward_lax): Move functions to isearch.el
12196 (bug#10145, bug#11381).
12198 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12200 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12202 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12204 * lread.c (init_obarray): Declare Qt and Qnil as special.
12206 2012-05-14 Glenn Morris <rgm@gnu.org>
12208 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12209 Put "libexec" before "bin", for the sake of init_callproc_1.
12211 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12213 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12215 * unexaix.c: Port to more-recent AIX compilers.
12216 (report_error, report_error_1, make_hdr, copy_sym)
12217 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12218 Make arguments const char *, not char *, to avoid violations of C
12219 standard and to fix some AIX warnings reported by Gilles Pion.
12221 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12223 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12224 already have overlays loaded.
12225 (handle_single_display_spec): Before returning without displaying
12226 fringe bitmap, synchronize the bidi iterator with the main display
12227 iterator, by calling iterate_out_of_display_property.
12228 (iterate_out_of_display_property): Detect buffer iteration by
12229 testing that it->string is a Lisp string.
12230 (get_next_display_element): When the current object is exhausted,
12231 and there's something on it->stack, call set_iterator_to_next to
12232 proceed with what's on the stack, instead of returning zero.
12233 (set_iterator_to_next): If called at the end of a Lisp string,
12234 proceed to consider_string_end without incrementing string
12235 position. Don't increment display vector index past the end of
12236 the display vector. (Bug#11417)
12237 (pos_visible_p): Don't report a position visible when move_it_to
12238 stopped at the last line of window, which happens to be scanned
12239 backwards by the bidi iteration. (Bug#11464)
12241 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12243 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12244 and right-margin display specs even if the spec is invalid or we
12245 are on a TTY, and thus unable to display on the fringes.
12246 That's because the text with the property will not be displayed anyway,
12247 so we need to signal to the caller that this is a "replacing"
12248 display spec. This fixes display when the spec is invalid or we
12251 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12253 * unexaix.c (make_hdr): Fix typo in prototype.
12254 This bug broke the build on AIX. Problem reported by Gilles Pion.
12256 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12258 * keyboard.c (kbd_buffer_get_event): Read special events also in
12259 batch mode. (Bug#11415)
12261 2012-05-12 Glenn Morris <rgm@gnu.org>
12263 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12265 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12267 * lisp.mk (lisp): Add newcomment.elc.
12269 2012-05-12 Glenn Morris <rgm@gnu.org>
12271 * Makefile.in (MKDIR_P): New, set by configure.
12272 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12274 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12276 Remove unused function hourglass_started.
12277 * dispextern.h (hourglass_started):
12278 * w32fns.c (hourglass_started):
12279 * xdisp.c (hourglass_started): Remove.
12281 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12283 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12284 Update dependencies.
12286 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12288 * xgselect.c (xg_select): Put maxfds+1 into a var.
12289 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12291 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12293 2012-05-10 Dave Abrahams <dave@boostpro.com>
12295 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12296 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12298 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12300 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12301 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12302 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12303 Initialize xd_registered_buses.
12305 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12307 Untag more efficiently if USE_LSB_TAG.
12308 This is based on a proposal by YAMAMOTO Mitsuharu in
12309 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12310 For an admittedly artificial (nth 8000 longlist) benchmark on
12311 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12312 Emacs's overall text size by 1%.
12313 * lisp.h (XUNTAG): New macro.
12314 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12315 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12316 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12317 * eval.c (Fautoload):
12318 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12319 * frame.h (XFRAME): Use XUNTAG.
12321 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12322 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12323 Remove unportable assumptions about print widths of types like
12325 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12326 intptr_t when converting between pointer and integer, to avoid GCC
12327 warnings about wrong width.
12329 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12331 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12332 stack for each reader_thread, instead of defaulting to 8MB
12333 determined by the linker. This avoids failures in creating
12334 subprocesses on Windows 7, see the discussion in this thread:
12335 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12337 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12339 Fix up display of the *Minibuf-0* buffer in the mini window.
12340 * keyboard.c (read_char): Don't clear the echo area if there's no
12342 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12343 contents of *Minibuf-0*) if there's no message displayed in its stead.
12345 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12347 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12350 2012-05-06 Chong Yidong <cyd@gnu.org>
12352 * lisp.mk (lisp): Update.
12354 2012-05-05 Jim Meyering <meyering@redhat.com>
12356 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12358 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12360 * data.c (PUT_ERROR): New macro.
12361 (syms_of_data): Use it. Add new error type `user-error'.
12362 * undo.c (user_error): New function.
12363 (Fprimitive_undo): Use it.
12364 * print.c (print_error_message): Adjust print style for `user-error'.
12365 * keyboard.c (user_error): New function.
12366 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12368 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12370 Do not limit current-time-string to years 1000..9999.
12371 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12372 (Fcurrent_time_string): Support any year that is supported by the
12373 underlying localtime representation. Don't use asctime, as it
12374 has undefined behavior for years outside the range -999..9999.
12376 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12378 Fix race conditions involving setenv, gmtime, localtime, asctime.
12379 Without this fix, interrupts could mess up code that uses these
12380 nonreentrant functions, since setting TZ invalidates existing
12381 tm_zone or tzname values, and since most of these functions return
12382 pointers to static storage.
12383 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12384 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12385 Grow the critical sections to include not just invoking
12386 localtime/gmtime, but also accessing these functions' results
12387 including their tm_zone values if any, and any related TZ setting.
12388 (format_time_string): Last arg is now struct tm *, not struct tm **,
12389 so that the struct tm is saved in the critical section.
12390 All callers changed. Simplify allocation of initial buffer, partly
12391 motivated by the fact that memory allocation needs to be outside
12392 the critical section.
12394 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12396 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12397 with RESET_INTERVAL.

12408 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12410 * xdisp.c (pos_visible_p): If already at a newline from the
12411 display string before the 'while' loop, don't walk back the glyphs
12412 from it3.glyph_row. Solves assertion violation when the display
12413 string begins with a newline (egg.el). (Bug#11367)
12415 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12417 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):

12423 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12424 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12425 All were removed before 23.1.
12427 * dispnew.c: Remove HAVE_LIBNCURSES test;
12428 it is always true on relevant platforms.
12430 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12431 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

12438 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12441 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12443 Do not avoid creating empty evaporating overlays (Bug#9642).
12444 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12445 That is, do not delete an evaporating overlay if it becomes
12446 empty after its bounds are adjusted to fit within its buffer.
12447 This fix caused other problems, and I'm reverting it until we get
12448 to the bottom of them.
12450 2012-04-27 Chong Yidong <cyd@gnu.org>
12452 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12454 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12456 * xdisp.c (pos_visible_p): If the window start position is beyond
12457 ZV, start the display from buffer beginning. Prevents assertion
12458 violation in init_iterator when the minibuffer window is scrolled
12459 via the scroll bar.
12461 * window.c (window_scroll_pixel_based): Likewise.
12463 2012-04-27 Chong Yidong <cyd@gnu.org>
12465 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12467 2012-04-27 Glenn Morris <rgm@gnu.org>
12469 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12470 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12472 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12474 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12475 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12477 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12479 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12480 display element, check also the underlying string or buffer
12481 character. (Bug#11341)
12483 * w32menu.c: Include w32heap.h.
12484 (add_menu_item): If the call to AppendMenuW (via
12485 unicode_append_menu) fails, disable Unicode menus only if we are
12486 running on Windows 9X/Me.
12488 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12490 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12491 (xgetint): Add missing shift for LSB tags.
12493 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12495 * keyboard.c (read_char): Don't wipe echo area for select window
12496 events: These might get delayed via `mouse-autoselect-window'
12499 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12501 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12502 manipulation of :loaded-from data.
12504 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12506 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12507 now a cons (bug#11311).
12509 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12511 Do not create empty overlays with the evaporate property (Bug#9642).
12512 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12513 if it becomes empty after its bounds are adjusted to fit within
12514 its buffer. Without this fix, in a nonempty buffer (let ((o
12515 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12516 yields an empty overlay that has the evaporate property, which is
12517 not supposed to happen.
12519 Fix minor GTK3 problems found by static checking.
12520 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12539 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12540 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12541 (__malloc_size_t, __malloc_ptrdiff_t):
12542 Remove. All uses removed, replaced by the definiens if needed,
12543 since we can assume C89 or better now.
12544 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12552 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12553 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12554 Define using prototypes, not old style.

12619 * alloc.c: Handle unusual debugging option combinations.
12620 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
12621 since the two debugging options are incompatible.
12622 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

12632 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12634 * sysdep.c [__FreeBSD__]: Minor cleanups.
12635 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12636 Use Emacs indenting style more consistently. Avoid some casts.
12637 Use 'double' consistently rather than mixing 'float' and 'double'.
12639 2012-04-21 Eduard Wiebe <usenet@pusto.de>
12641 * sysdep.c (list_system_processes, system_process_attributes):

12648 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12650 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12651 It is never used otherwise.
12653 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12655 * print.c (print_preprocess): Only check print_depth if print-circle
12657 (print_object): Check for cycles even when print-circle is nil and
12658 print-gensym is t, but only check print_depth if print-circle is nil.
12660 2012-04-20 Chong Yidong <cyd@gnu.org>
12662 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12663 set the status to "failed" and ensure that sentinel is run.
12665 2012-04-20 Glenn Morris <rgm@gnu.org>
12667 * process.c (Fset_process_inherit_coding_system_flag)

12676 row, return zero immediately.
12677 (try_cursor_movement): If inside continuation line, don't back up
12678 farther than the first row after the header line, if any.
12679 Don't consider the header-line row as "partially visible", even if

12720 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12721 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12722 (NEED_MEM_INSERT): New macro.
12723 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12724 Remove one incorrect comment and fix another.

12728 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
12729 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12730 (r_alloc_sbrk): Now static.
12732 Improve ralloc.c interface checking.
12733 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12734 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

12760 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12761 * s/netbsd.h, s/sol2-6.h:
12762 Remove definition of GC_MARK_STACK, since the default now works.
12763 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12764 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12765 no longer the default.
12766 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12768 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12770 * lread.c (lisp_file_lexically_bound_p):

12791 2012-04-11 Daniel Colascione <dancol@dancol.org>
12793 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12794 against is gone. It's better to use vfork now so that when Cygwin
12795 gains a new, working vfork, we use it automatically (bug#10398).
12797 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12817 * w32.c (w32_delayed_load): Record the full path of the library
12818 being loaded (bug#10424).
12820 2012-04-09 Glenn Morris <rgm@gnu.org>
12822 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12823 not just in the obarray, before snarfing them. (Bug#11036)
12825 * Makefile.in ($(leimdir)/leim-list.el):
12826 Pass EMACS rather than BUILT_EMACS.
12828 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12830 * process.c (make_process):
12831 * process.h: Add integer `gnutls_handshakes_tried' member to
12834 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12835 Add convenience `GNUTLS_LOG2i' macro.
12837 * gnutls.c (gnutls_log_function2i): Convenience log function.
12838 (emacs_gnutls_read): Use new log functions,
12839 `gnutls_handshakes_tried' process member, and
12840 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12841 attempts per process (connection).
12843 2012-04-09 Chong Yidong <cyd@gnu.org>
12845 * eval.c (Fuser_variable_p, user_variable_p_eh)

12850 * minibuf.c (Fread_variable): Callers changed.
12852 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12854 * xdisp.c (set_cursor_from_row): If the display string appears in
12855 the buffer at position that is closer to point than the position
12856 after the display string, display the cursor on the first glyph of
12857 the display string. Fixes cursor display when a 'display' text
12858 property immediately follows invisible text. (Bug#11094)
12860 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12862 composite.c: use 'double' consistently
12863 * composite.c (get_composition_id): Use 'double' consistently
12864 instead of converting 'float' to 'double' and vice versa; this is
12865 easier to understand and avoids a GCC warning.
12867 2012-04-09 Glenn Morris <rgm@gnu.org>
12869 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12870 preparation for dumping it with emacs. (Bug#4789)
12871 (leimdir): New variable.
12872 ($(leimdir)/leim-list.el): New rule.
12873 (emacs$(EXEEXT)): Depend on leim-list.el.

12889 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12891 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12892 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12893 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12894 objects, as mark_maybe_pointer will catch them otherwise.
12895 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12896 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12900 Fix typo that broke non-Windows builds.
12901 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12903 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12905 Support building on MS-Windows with libxml2.
12907 * makefile.w32-in (OBJ2): Add xml.$(O).
12908 (GLOBAL_SOURCES): Add xml.c.
12909 ($(BLD)/xml.$(O)): New dependency list.
12911 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12912 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12913 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12914 [!WINDOWSNT]: New macros.
12915 (init_libxml2_functions, libxml2_loaded_p): New functions.
12916 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12917 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12918 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12919 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12921 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12922 Call init_libxml2_functions before calling libxml2 functions.
12923 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12925 * emacs.c: Don't include libxml/parser.h.
12926 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12927 xmlCleanupParser directly.
12929 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12931 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12933 * indent.c (Fvertical_motion): If there is a display string at
12934 point, use it.vpos to compute how many lines to backtrack after
12935 move_it_to point. (Bug#11133)
12937 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12939 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12940 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12941 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12942 macros related to unification of CJK characters. For the details,
12943 see the discussion following the message here:
12944 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12946 2012-04-04 Chong Yidong <cyd@gnu.org>
12948 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12950 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12952 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12953 instead of alloca. (Bug#11138)
12955 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12957 * w32menu.c (is_simple_dialog): Properly check lisp types.
12960 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12962 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12963 position we get to after a call to move_it_to fails the
12964 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12965 only if we wind up in a string from display property. (Bug#11063)
12967 * window.c (Fdelete_other_windows_internal): Invalidate the row
12968 and column information about mouse highlight, so that redisplay
12969 restores it after reallocating the glyph matrices. (Bug#7464)
12971 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12972 string comes from a `display' text property, use the buffer
12973 position of that property as if we actually saw that position in
12975 (move_it_by_lines): Remove the assertion that
12976 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12977 violated when there's a before-string at the beginning of a line.
12980 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12982 * xdisp.c (append_space_for_newline): If the default face was
12983 remapped, use the remapped face for the appended newline.
12984 (extend_face_to_end_of_line): Use the remapped default face for
12985 extending the face to the end of the line.
12986 (display_line): Call extend_face_to_end_of_line when the default
12987 face was remapped. (Bug#11068)
12989 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12991 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12993 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12995 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12997 2012-03-27 Glenn Morris <rgm@gnu.org>
12999 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13002 2012-03-26 Kenichi Handa <handa@m17n.org>
13004 * dispextern.h (struct glyph): Fix previous change. Change the
13005 bit length of glyphless.ch to 25 (Bug#11082).
13007 2012-03-26 Chong Yidong <cyd@gnu.org>
13009 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13010 (command_loop_1): Use it; inhibit selection update for
13011 handle-select-window too (Bug#8996).
13013 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13015 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13017 2012-03-25 Kenichi Handa <handa@m17n.org>
13019 * dispextern.h (struct glyph): Change the bit length of
13020 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13022 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13024 * s/ms-w32.h (tzname): Include time.h before redirecting to
13025 _tzname. Fixes the MSVC build. (Bug#9960)
13027 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13029 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13032 * xterm.c (XTread_socket): Only modify handling_signal if
13033 !SYNC_INPUT. (Bug#11080)
13035 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13037 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13038 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13039 when fetching a multibyte character consumes more bytes than
13040 CHAR_BYTES returns, due to unification of CJK characters in
13041 string_char. (Bug#11073)
13043 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13045 * process.c (wait_reading_process_output): Handle pty disconnect
13046 by refraining from sending oneself a SIGCHLD (bug#10933).
13048 2012-03-22 Chong Yidong <cyd@gnu.org>

13053 Mark string as coming from a prefix property.
13054 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13055 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13057 2012-03-21 Chong Yidong <cyd@gnu.org>
13059 * xfaces.c (Vface_remapping_alist): Doc fix.
13061 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13063 * w32proc.c (Fw32_set_console_codepage)
13064 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13067 2012-03-20 Chong Yidong <cyd@gnu.org>
13069 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13070 to reflect default non-nil value of redisplay-dont-pause.
13072 2012-03-19 Kenichi Handa <handa@m17n.org>
13074 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13075 it fit in a valid range (Bug#11003).
13077 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13079 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13080 that is not from display property, accept the row as a "cursor
13081 row" if one of the string's character has a non-nil `cursor'
13082 property. Fixes cursor positioning when there are newlines in
13083 overlay strings, e.g. in icomplete.el. (Bug#11035)
13085 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13087 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13089 2012-03-12 Chong Yidong <cyd@gnu.org>
13091 * eval.c (inhibit_lisp_code): Rename from
13092 inhibit_window_configuration_change_hook; move from window.c.
13094 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13095 * window.c (run_window_configuration_change_hook)
13096 (syms_of_window): Callers changed.
13098 2012-03-11 Chong Yidong <cyd@gnu.org>

13104 2012-03-10 Chong Yidong <cyd@gnu.org>
13106 * frame.c (other_visible_frames): Don't assume the selected frame
13107 is visible (Bug#10955).
13109 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13111 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13113 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13115 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13116 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13119 2012-03-03 Glenn Morris <rgm@gnu.org>
13121 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13123 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13125 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13126 position past the first glyph_row that ends at ZV. (Bug#10902)
13127 (redisplay_window, next_element_from_string): Fix typos in
13129 (redisplay_window): Pass to move_it_vertically the margin in
13130 pixels, not in screen lines.
13132 2012-03-02 Glenn Morris <rgm@gnu.org>
13134 * buffer.c (buffer-list-update-hook): Doc fix.
13136 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13138 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13139 push_it before setting up the iterator for the first overlay
13140 string, even if we have an empty string loaded.
13141 (next_overlay_string): If there's an empty string on the iterator
13142 stack, pop the stack. (Bug#10903)
13144 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13146 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13147 Suggested by Stefan Monnier in
13148 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13149 * alloc.c (widen_to_Lisp_Object): New static function.
13150 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13151 and widening them to Lisp_Objects. This would work even if
13152 USE_LSB_TAG is defined and wide integers are used, which might
13153 happen in a future version of Emacs.
13155 2012-02-25 Chong Yidong <cyd@gnu.org>
13157 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13160 * xselect.c (Fx_selection_exists_p): Doc fix.
13161 (x_clipboard_manager_save_all): Print an informative message
13162 before saving to clipboard manager.
13164 2012-02-24 Chong Yidong <cyd@gnu.org>
13166 * keyboard.c (process_special_events): Handle all X selection
13167 requests in kbd_buffer, not just the next one (Bug#8869).
13169 2012-02-23 Chong Yidong <cyd@gnu.org>
13171 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13172 call when setting menu-bar-lines and tool-bar-lines parameters.
13173 (unwind_create_frame_1): New helper function.
13175 * window.c (inhibit_window_configuration_change_hook): New var.

13194 when computing $valmask.
13196 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13197 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13198 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13199 It's useless in that case, and it can cause problems on hosts
13200 that allocate halves of EMACS_INT values separately.
13201 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13202 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13203 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13204 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13205 it avoids undefined behavior on hosts where shifting right by more
13206 than the word width has undefined behavior.
13208 2012-02-19 Chong Yidong <cyd@gnu.org>
13210 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13211 (Funhandled_file_name_directory, Ffile_name_as_directory)
13212 (Fdirectory_file_name, Fexpand_file_name)
13213 (Fsubstitute_in_file_name): Protect against invalid file handler
13214 return values (Bug#10845).
13216 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13218 * .gdbinit (pitx): Fix incorrect references to fields of the

13225 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13227 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13228 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13230 2012-02-15 Chong Yidong <cyd@gnu.org>
13232 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13233 marked as special. Also, starting docstrings with * is obsolete.
13235 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13237 * gnutls.c (emacs_gnutls_write): Fix last change.

13248 2012-02-12 Chong Yidong <cyd@gnu.org>
13250 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13251 as that creates a dangerous corner case.
13253 * window.c (Fdelete_window_internal): Invalidate the mouse
13254 highlight (Bug#9904).
13256 2012-02-12 Glenn Morris <rgm@gnu.org>
13258 * xselect.c (Fx_own_selection_internal)
13259 (Fx_get_selection_internal, Fx_disown_selection_internal)
13260 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13261 * nsselect.m (Fx_own_selection_internal)
13262 (Fx_disown_selection_internal, Fx_selection_exists_p)
13263 (Fx_selection_owner_p, Fx_get_selection_internal):
13264 Sync docs and argument specs with the xselect.c versions.
13266 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13268 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13270 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13272 * w32select.c (Fx_selection_exists_p): Sync doc string and
13273 argument list with xselect.c. (Bug#10783)
13275 * w16select.c (Fx_selection_exists_p): Sync doc string and
13276 argument list with xselect.c. (Bug#10783)

13286 2012-02-07 Chong Yidong <cyd@gnu.org>
13288 * buffer.c (Fbuffer_local_variables)
13289 (buffer_lisp_local_variables): Handle unbound vars correctly;
13290 don't let Qunbound leak into Lisp.
13292 2012-02-07 Glenn Morris <rgm@gnu.org>

13823 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13824 verifies glyph row's hash code--we have just reallocated the
13825 glyphs, so their contents can be complete garbage. (Bug#10164)

13871 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13872 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13873 this macro definition.

13904 (start_display): Don't move to the next line if the display should
13905 start at a newline that is part of a display vector or an overlay

13985 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13986 Otherwise, valgrind does not work on some platforms.
13987 Problem reported by Andreas Schwab in
13988 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13989 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13990 is set, removing the need for VIRT_ADDRESS_VARIES.
13991 (PURE_P): Use a more-efficient implementation that needs just one
13992 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13993 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13994 to 4 (xorl, subq, cmpq, setbe).
13995 * alloc.c (pure): Always extern now, since that's the
13996 VIRT_ADDR_VARIES behavior.
13997 (PURE_POINTER_P): Use a single comparison, not two, for
13998 consistency with the new puresize.h.
13999 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14000 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14006 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14007 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14008 behave as if the cursor position were at the window margin.
14010 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14011 and the cursor position is out of bounds, behave as if the cursor
14012 position were at the window margin. (Bug#10075)
14014 2011-11-18 Chong Yidong <cyd@gnu.org>
14016 * window.c (Fwindow_combination_limit): Make first argument

14035 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14037 * xdisp.c (row_hash): New function, body extracted from
14038 compute_line_metrics.
14039 (compute_line_metrics): Call row_hash, instead of computing the
14042 * dispnew.c (verify_row_hash): Call row_hash for computing the
14043 hash code of a row, instead of duplicating code from xdisp.c.
14045 * dispextern.h (row_hash): Add prototype.
14047 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14049 * frame.c (delete_frame): Don't delete the terminal when the last

14075 (Fsplit_window_internal, saved_window)
14076 (Fset_window_configuration, save_window_save): Rename all
14077 occurrences of window_nest to window_combination_limit.

14083 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14085 * xdisp.c (display_line): Move the call to
14086 highlight_trailing_whitespace before the call to
14087 compute_line_metrics, since the latter needs to see the final
14088 faces of all the glyphs to compute ROW's hash value.
14089 Fixes assertion violations in row_equal_p. (Bug#10035)
14091 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14093 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

14098 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14099 with user-defined heap size. Bump the default size of the temacs

14103 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14104 current_matrix and desired_matrix. (Bug#9990)
14105 (verify_row_hash) [XASSERTS]: New function.

14150 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14152 Avoid some portability problems by eschewing 'extern inline' functions.
14153 The trivial performance wins aren't worth the portability hassles; see
14154 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14156 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14231 (window_box_right, window_box_right_offset): Declare extern.
14232 Otherwise, these inline functions do not conform to C99 and
14233 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14234 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14235 * intervals.c (adjust_intervals_for_insertion)
14236 (adjust_intervals_for_deletion): Now extern, because otherwise the

14238 (static_offset_intervals): Remove.
14239 (offset_intervals): Rewrite using the old contents of
14240 static_offset_intervals. The old version didn't conform to C99
14241 because an extern inline function contained a reference to an
14242 identifier with static linkage.

14478 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14479 instead of calling the "wide" APIs directly.

14494 * process.c (make_process): Set gnutls_state to NULL.
14496 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14497 non-NULL, regardless of GNUTLS_INITSTAGE.

14546 (bidi_resolve_weak): Don't enter the expensive loop if the current
14547 position is before next_en_pos. Record the bidi type of the first
14548 non-ET, non-BN character we find, in addition to its position.
14549 (bidi_level_of_next_char): Invalidate next_en_type when
14550 next_en_pos is over-stepped.
14552 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14554 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14555 * editfns.c: Rewrite current-time-zone so that it invokes
14556 the equivalent of (format-time-string "%Z") to get the time zone name.
14557 This fixes a bug when the time zone name contains characters that
14558 need converting from the system time locale to Emacs internal format.
14559 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14560 that patch fixed format-time-string to do the conversion, but
14561 I forgot to fix current-time-zone.
14562 (format_time_string): New function, containing most of
14563 what Fformat_time_string used to contain.
14564 (Fformat_time_string): Rewrite in terms of format_time_string.
14565 This doesn't change this function's behavior.
14566 (current-time-zone): Rewrite to use format_time_string.
14567 This fixes the bug reported by Michael Schierl in
14568 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14569 Jason Rumney's 2007-06-07 change worked around this bug, but
14571 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14573 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14575 * xdisp.c (start_display): If the character at POS is displayed
14576 via a display vector, reset IT->current.dpvec_index to zero.
14577 (try_window_reusing_current_matrix): If a line ends in a display
14578 vector or the next line starts in a display vector, continue
14579 redrawing the window even though the character position of
14580 start_row was reached.
14583 2011-10-18 Chong Yidong <cyd@gnu.org>
14585 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14586 with nobreak-char-display too.
14588 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14590 Fix part 3 of bug#9771.
14591 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14592 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14593 non-neutral characters if the current character is a paragraph
14594 separator (a.k.a. Newline). This avoids running the same
14595 expensive loop twice, once when we consume the preceding newline
14596 and the other time when the line actually needs to be displayed.
14597 Avoid the loop when we see neutrals on the base embedding level
14598 following a character whose directionality is the same as the
14599 paragraph's. This avoids running the expensive loop when a line
14600 ends in a long sequence of neutrals, like control characters.
14601 Add assertion against STRONG_AL type. Slightly rearrange code
14602 that determines the type of a neutral given the first non-neutral
14604 (bidi_level_of_next_char): Set next_en_pos to zero when
14605 invalidating its info.
14607 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14609 * xdisp.c (push_display_prop): Determine whether to record string
14610 or buffer position by IT->string, not by IT->method. Allow
14611 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14612 (move_it_vertically_backward): Don't look for character position
14613 immediately after the newline when in a continuation line.
14616 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14618 * window.c (coordinates_in_window): Rewrite and delabelize
14619 vertical border check. (Bug#5357) (Bug#9618)

14623 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14624 errors in XSetWindowBorder (bug#9310).
14626 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14628 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14629 avoid crash when xmalloc overrun checking is enabled.
14631 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14633 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14634 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14635 cursor motion with <left> and <right> arrow keys.
14637 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14638 some callers set that themselves.
14640 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14642 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14643 display string and the previous row comes from the same string and
14644 is empty. (Bug#9739) (Bug#9738)
14646 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14648 * doc.c (get_doc_string): Encode file name (bug#9735).

14652 * bidi.c (bidi_level_of_next_char):
14653 * xdisp.c (get_visually_first_element): Remove old incorrect
14654 comments regarding the Unicode Line Separator character.
14656 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14658 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

14664 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14666 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14667 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14669 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14670 Some packages use them to denote characters with modifiers.
14672 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14674 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14675 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14676 matching a pp-number. Rename parameter var to var1.
14678 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14680 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).

14684 * callint.c (Fcall_interactively): Give a more explicit error for the
14685 'c' case with a non-character input. (Bug#8479)

14689 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14691 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14692 lines that are hscrolled on the left.
14694 * dispnew.c (buffer_posn_from_coords): Account for a possible
14695 presence of header-line. (Bug#4426)
14697 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14699 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14700 Don't advertise functionality which we discourage or doesn't work.
14702 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14704 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14705 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14706 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14707 this makes Emacs dump core during garbage collection on rare
14708 occasions. sizeof is obviously inferior to offsetof here, so
14709 stick with offsetof.
14710 (GC_POINTER_ALIGNMENT): New macro.
14711 (mark_memory): Omit 3rd (offset) arg; caller changed.
14712 Don't assume EMACS_INT alignment is the same as pointer alignment.
14714 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14716 * keyboard.c (read_key_sequence_remapped): New var.
14717 (read_key_sequence): Compute remapping in the right buffer.
14718 (command_loop_1): Use read_key_sequence's remapping directly.
14720 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14722 * dired.c (file_name_completion): Don't expand file name.
14723 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14724 before checking file name handler.
14726 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14727 they've been requested explicitly (bug#9591).
14729 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14731 * keymap.c (Fsingle_key_description): Use make_specified_string
14732 instead of build_string to build string from push_key_description.
14735 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14737 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14738 This fixes a Y2038 bug on 64-bit hosts.
14739 * buffer.c (reset_buffer):
14740 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14741 (Fclear_buffer_auto_save_failure):
14742 Use 0, not -1, to represent an unset failure time, since time_t
14743 might not be signed.
14745 Remove dependency on glibc malloc internals.
14746 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14747 Move back here from lisp.h, but with their new implementations.
14748 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14749 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14750 * charset.c (charset_table_init): New static var.
14751 (syms_of_charset): Use it instead of xmalloc. This removes a
14752 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14753 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14754 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14755 Move back to alloc.c.
14756 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14757 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14759 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14761 * nsterm.m (windowDidResize): Call x_set_window_size only when
14762 ns_in_resize is true. Otherwise set pixelwidth/height and
14763 call change_frame_size (Bug#9628).
14765 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14767 Port --enable-checking=all to Fedora 14 x86-64.
14768 * charset.c (syms_of_charset): Also account for glibc malloc's
14769 internal overhead when calculating the initial malloc maximum.
14771 Port --enable-checking=all to Fedora 14 x86.
14772 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14774 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14775 (overrun_check_realloc, overrun_check_free):
14776 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14777 That way, xmalloc returns a properly-aligned pointer even if
14778 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14779 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14780 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14781 into account when calculating the initial malloc maximum.
14782 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14783 Move here from alloc.c, so that charset.c can use it too.
14784 Properly align; the old code wasn't right for common 32-bit hosts
14785 when configured with --enable-checking=all.
14786 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14787 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14789 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14791 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14794 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14796 * xdisp.c (compute_display_string_end): If there's no display
14797 string at CHARPOS, return -1.
14799 * bidi.c (bidi_fetch_char): When compute_display_string_end
14800 returns a negative value, treat the character as a normal
14801 character not covered by a display string. (Bug#9624)
14803 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14805 * lread.c (Fread_from_string): Fix typo in docstring.
14807 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14809 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14810 newline, reseat the iterator instead of bidi-iterating there one
14811 character at a time. (Bug#9610)
14812 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14813 TO_CHARPOS if the bidi iterator is at base embedding level.
14815 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14817 * lread.c (readevalloop): Use correct code for NBSP.
14818 (read1): Likewise. (Bug#9608)
14820 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14822 * dbusbind.c (Fdbus_register_signal): When service is not
14823 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14825 2011-09-25 Glenn Morris <rgm@gnu.org>
14827 * buffer.c (truncate-lines): Doc fix.
14829 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14831 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14832 (Fset_window_next_buffers): Doc fix.
14834 2011-09-24 Glenn Morris <rgm@gnu.org>
14836 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14838 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14840 Fix minor problems found by static checking.
14841 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14842 * indent.c (Fvertical_motion): Fix == vs = typo.
14844 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14846 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14847 Default value is now t. Doc fix.
14849 * indent.c (Fvertical_motion): Compute and apply the overshoot
14850 logic when moving up, not only when moving down. Fix the
14851 confusing name and values of the it_overshoot_expected variable;
14852 logic changes accordingly. (Bug#9254) (Bug#9549)
14854 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14855 CHARPOS is covered by a display string which includes newlines.
14856 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14857 is covered by a display string with embedded newlines.
14859 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14861 * dbusbind.c (Fdbus_register_signal): Add match rule to
14862 Vdbus_registered_objects_table. (Bug#9581)
14863 (Fdbus_register_method, Vdbus_registered_objects_table):
14866 2011-09-24 Jim Meyering <meyering@redhat.com>
14868 do not ignore write error for any output size
14869 The previous change was incomplete.
14870 While it makes emacs --batch detect the vast majority of stdout
14871 write failures, errors were still ignored whenever the output size is
14872 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14873 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14874 && echo FAIL: ignored write error
14875 FAIL: ignored write error
14876 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14877 && echo FAIL: ignored write error
14878 FAIL: ignored write error
14879 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14881 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14883 * emacs.c (Fkill_emacs): In noninteractive mode exit
14884 non-successfully if a write error occurred on stdout. (Bug#9574)
14886 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14888 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14891 * dispextern.h (struct it): Update the comment documenting what
14894 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14896 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14897 a display string, extend search for cursor position to end of row.
14898 (find_row_edges): If the row ends in a newline from a display
14899 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14900 Handle the case of a display string with multiple newlines.
14901 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14902 non-empty line. Fixes confusing cursor motion with arrow keys at
14903 the beginning of a line that starts with whitespace.
14905 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14907 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14910 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14912 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14913 boolean (Bug#9154).
14915 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14917 * xdisp.c (display_line): Record maximum and minimum buffer
14918 positions even if no glyphs were produced (e.g., by a zero-width
14919 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14920 buffer positions that will be removed from the glyph row because
14922 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14923 column is beyond frame width: don't subtract 1 "pixel" when
14924 computing width of the stretch.
14925 (reseat_at_next_visible_line_start): Undo the change made on
14926 2011-09-17 that saved paragraph information and restored it after
14927 the call to `reseat'. (Bug#9545)
14929 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14931 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14932 and turn window cursor on if cleared (Bug#9415).
14934 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14936 * search.c (boyer_moore): Take unibyte characters from pattern
14937 literally. (Bug#9458)
14939 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14941 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14943 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14945 Fix minor problem found by static checking.
14946 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14947 initialized, to pacify gcc -Wuninitialized.
14949 * fileio.c: Report proper errno when syscall falls.
14950 (Finsert_file_contents): Save and restore errno,
14951 so that report_file_error outputs the correct diagnostic.
14952 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14954 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14956 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14958 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14960 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14961 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14963 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14965 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14966 about the current paragraph and restore it after the call to reseat.
14968 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14969 (bidi_find_paragraph_start): Search back for paragraph beginning
14970 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14971 (bidi_move_to_visually_next): Only trigger paragraph-related
14972 computations when the last character is a newline or at EOB, not
14973 just any NEUTRAL_B. (Bug#9470)
14975 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14976 truncated lines if point is covered by a display string. (Bug#9524)
14978 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14980 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14981 (cons_to_x_long): New function.
14982 (lisp_data_to_selection_data): Use it. Correct the test for
14983 short-versus-long data; it was negated. Break out of vector
14984 loop, for efficiency, when a long datum is discovered.
14986 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14988 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14990 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14992 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14993 GCC PR/17406) by declaring this function with external scope.
14995 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14997 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14998 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15000 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15002 * editfns.c (Fformat): Correctly handle text properties on "%%".
15004 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15006 * xterm.c (x_draw_composite_glyph_string_foreground):
15007 * w32term.c (x_draw_composite_glyph_string_foreground):
15008 * term.c (encode_terminal_code):
15009 * composite.c (composition_update_it, get_composition_id):
15010 * xdisp.c (get_next_display_element)
15011 (fill_composite_glyph_string): Add comments about special meaning
15012 of TAB characters in a composition.
15014 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15016 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15017 This occurs when processing a multibyte format.
15018 Problem reported by Wolfgang Jenker.
15020 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15022 * xdisp.c (try_cursor_movement): Only check for exact match if
15023 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15025 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15027 Remove unused external symbols.
15028 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15029 * xdisp.c (calc_pixel_width_or_height): Now static.
15030 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15031 * indent.c (check_display_width):
15032 * w32term.c: Fix comment to match code.
15033 * xterm.c, xterm.h (x_catching_errors): Remove.
15035 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15037 * xselect.c: Use signed conversions more consistently (Bug#9498).
15038 (selection_data_to_lisp_data): Assume incoming selection data are
15039 signed integers, not unsigned. This is to be consistent with
15040 outgoing selection data, which was modified to use signed integers
15041 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15042 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15043 expects long, not unsigned long.
15045 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15047 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15048 computation of loop end. Reported by Johan Bockgård
15051 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15053 * frame.c (Fother_visible_frames_p): Function deleted.
15055 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15057 * indent.c (compute_motion): Process display vector front to back
15058 rather than the other way around. (Bug#2496)
15060 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15062 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15064 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15066 * minibuf.c (Fread_from_minibuffer): Doc fix.
15068 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15070 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15071 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15073 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15075 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15076 value for non-existent files.
15078 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15080 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15081 set its "size" to -1. This will set the modtime_size field of
15082 the corresponding buffer to -1, which is what
15083 verify-visited-file-modtime expects for files that do not exist.
15086 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15088 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15090 * lisp.h: ... from here. push_key_description is no longer
15091 defined in keyboard.c, so its declaration should not be in
15092 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15093 logically belongs with push_key_description.
15095 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15097 * buffer.h: Include <sys/types.h> instead of <time.h>.
15098 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15099 Problem reported by Herbert J. Skuhra.
15101 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15103 * xml.c (parse_region): Make the parsing work for
15104 non-comment-starting XML files again (bug#9144).
15106 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15108 * image.c (gif_load): Fix calculation of bottom and right corner.
15111 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15113 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15114 redisplay in small windows.
15116 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15118 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15120 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15122 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15123 Operate on live windows only.
15125 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15127 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15129 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15131 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15132 only under bidi iteration.
15134 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15136 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15138 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15140 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15141 Without this fix, the command to link temacs failed due to an
15142 undefined symbol __builtin_isnan. This is because
15143 /usr/include/iso/math_c99.h #defines isnan(x) to
15144 __builtin_isnan(x), but the bundled gcc, which identifies itself
15145 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15147 * floatfns.c (isnan): #undef, and then #define to a clone of
15149 (Fisnan): Always define, since it's always available now.
15150 (syms_of_floatfns): Always define isnan at the Lisp level.
15152 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15154 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15156 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15158 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15159 The previous code assumed that file offsets (off_t values) fit in
15160 EMACS_INT variables, which is not true on typical 32-bit hosts.
15161 The code messed up by falsely reporting buffer overflow in cases
15162 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15163 when "big" contains more than 2**29 bytes, even though this
15164 inserts just one byte and does not overflow the buffer.
15165 (Finsert_file_contents): Store file offsets as off_t
15166 values, not as EMACS_INT values. Check for overflow when
15167 converting between EMACS_INT and off_t. When checking for
15168 buffer overflow or for overlap, take the offsets into account.
15169 Don't use EMACS_INT for small values where int suffices.
15170 When checking for overlap, fix a typo: ZV was used where
15171 ZV_BYTE was intended.
15172 (Fwrite_region): Don't assume off_t fits into 'long'.
15173 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15175 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15177 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15179 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15181 sprintf-related integer and memory overflow issues (Bug#9412).
15183 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15184 (esprintf, exprintf, evxprintf): New functions.
15185 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15186 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15187 (modify_event_symbol): Do not assume that the length of
15188 name_alist_or_stem is safe to alloca and fits in int.
15189 (Fexecute_extended_command): Likewise for function name and binding.
15190 (Frecursion_depth): Wrap around reliably on integer overflow.
15191 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15192 since some callers pass EMACS_INT values.
15193 (Fsingle_key_description): Don't crash if symbol name contains more
15194 than MAX_ALLOCA bytes.
15195 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15196 (get_minibuffer): Arg is now EMACS_INT, not int.
15197 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15198 (esprintf, exprintf, evxprintf): New decls.
15199 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15201 * dbusbind.c (signature_cat): New function.
15202 (xd_signature, Fdbus_register_signal):
15203 Do not overrun buffer; instead, report string overflow.
15205 * dispnew.c (add_window_display_history): Don't overrun buffer.
15206 Truncate instead; this is OK since it's just a log.
15208 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15209 even if the time zone offset is outlandishly large.
15210 Don't mishandle offset == INT_MIN.
15212 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15213 when creating daemon; the previous buffer-overflow check was incorrect.
15215 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15216 which has the guts of the old verror function.
15218 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15219 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15221 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15222 (font_unparse_xlfd): Don't blindly alloca long strings.
15223 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15224 fits in int, when using sprintf. Use single snprintf to count
15225 length of string rather than counting it via multiple sprintfs;
15226 that's simpler and more reliable.
15227 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15228 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15229 sprintf, in case result does not fit in int.
15231 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15232 (fontset_from_font): Print it.
15234 * frame.c (tty_frame_count): Now printmax_t, not int.
15235 (make_terminal_frame, set_term_frame_name): Print it.
15236 (x_report_frame_params): In X, window IDs are unsigned long,
15237 not signed long, so print them as unsigned.
15238 (validate_x_resource_name): Check for implausibly long names,
15239 and don't assume name length fits in 'int'.
15240 (x_get_resource_string): Don't blindly alloca invocation name;
15241 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15244 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15245 (xg_check_special_colors, xg_set_geometry):
15246 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15248 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15249 Use esprintf, not sprintf, in case result does not fit in int.
15251 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15252 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15253 it as a large positive number.
15254 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15255 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15257 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15258 in case result does not fit in int.
15260 * print.c (float_to_string): Detect width overflow more reliably.
15261 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15262 buffer overrun. Don't assume list length fits in 'int'. Treat
15263 print length of 0 as 0, not as infinity; to be consistent with other
15264 uses of print length in this function. Don't overflow print length
15265 index. Don't assume hash table size fits in 'long', or that
15266 vectorlike size fits in 'unsigned long'.
15268 * process.c (make_process): Use printmax_t, not int, to format
15269 process-name gensyms.
15271 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15273 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15274 to avoid potential buffer overrun.
15276 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15277 if X resource line is longer than 512 bytes.
15279 * xfns.c (x_window): Make sprintf buffer a bit bigger
15280 to avoid potential buffer overrun.
15282 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15284 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15286 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15288 Integer overflow fixes for scrolling, etc.
15289 Without these, Emacs silently mishandles large integers sometimes.
15290 For example, "C-u 4294967297 M-x recenter" was treated as if
15291 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15293 * xdisp.c (try_window_id): Check Emacs fixnum range before
15294 converting to 'int'.
15296 * window.c (window_scroll_line_based, Frecenter):
15297 Check that an Emacs fixnum is in range before assigning it to 'int'.
15298 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15299 values converted from Emacs fixnums.
15300 (Frecenter): Don't wrap around a line count if it is out of 'int'
15301 range; instead, treat it as an extreme value.
15302 (Fset_window_configuration, compare_window_configurations):
15303 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15305 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15306 that can exceed INT_MAX. Check that EMACS_INT value is in range
15307 before assigning it to the (possibly-narrower) index.
15308 (match_limit): Don't assume that a fixnum can fit in 'int'.
15310 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15313 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15314 (Fvertical_motion): Don't wrap around LINES values that don't fit
15315 in 'int'. Instead, treat them as extreme values. This is good
15316 enough for windows, which can't have more than INT_MAX lines anyway.
15318 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15320 * Require libxml/parser.h to avoid compilation warning.
15322 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15324 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15325 since this reportedly can destroy thread storage.
15327 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15329 * syntax.c (find_defun_start): Update all cache variables if
15330 exiting early (Bug#9401).
15332 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15334 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15336 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15337 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15338 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15340 * term.c (tty_append_glyph): New function.
15341 (produce_stretch_glyph): Static function and its prototype deleted.
15343 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15346 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15348 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15349 when checking :margin (Bug#9390).
15350 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15351 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15352 so that the name doesn't mislead. All uses changed.
15354 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15356 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15359 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15361 * xdisp.c (move_it_to): Don't bail out early when reaching
15362 position beyond to_charpos, if we are scanning backwards.
15363 (move_it_vertically_backward): When DY == 0, make sure we get to
15364 the first character in the line after the newline.
15366 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15368 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15369 (ccl_driver): Do not generate an out-of-range pointer.
15370 (Fccl_execute_on_string): Remove unnecessary check for
15371 integer overflow, noted by Stefan Monnier in
15372 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15373 Remove a FIXME that didn't need fixing.
15374 Simplify the newly-introduced buffer reallocation code.
15376 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15378 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15380 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15382 Integer and memory overflow issues (Bug#9196).
15384 * doc.c (get_doc_string): Rework so that
15385 get_doc_string_buffer_size is the actual buffer size, rather than
15386 being 1 less than the actual buffer size; this makes xpalloc more
15389 * image.c (x_allocate_bitmap_record, cache_image):
15390 * xselect.c (Fx_register_dnd_atom):
15391 Simplify previous changes by using xpalloc.
15393 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15394 since either will do and ptrdiff_t is convenient with xpalloc.
15396 * charset.c (charset_table_size)
15397 (struct charset_sort_data.priority): Now ptrdiff_t.
15398 (charset_compare): Don't overflow if priorities differ greatly.
15399 (Fsort_charsets): Don't assume list length fits in int.
15400 Check for size-calculation overflow when allocating sort data.
15401 (syms_of_charset): Allocate an initial charset table that is
15402 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15404 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15406 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15407 The actual value is always <= INT_MAX, and leaving it unsigned made
15408 overflow checking harder.
15410 * dispextern.h (struct glyph_matrix.rows_allocated)
15411 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15412 with xpalloc. The values are still always <= INT_MAX.
15414 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15416 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15417 (SAFE_NALLOCA): New macro.
15419 * region-cache.c (struct boundary.pos, find_cache_boundary)
15420 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15421 (set_cache_region, invalidate_region_cache)
15422 (revalidate_region_cache, know_region_cache, region_cache_forward)
15423 (region_cache_backward, pp_cache):
15424 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15425 so that ptrdiff_t * can be passed to xpalloc.
15426 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15427 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15428 (pp_cache): Don't assume cache_len fits in int.
15429 * region-cache.h: Adjust extern decls to match.
15431 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15432 EMACS_INT, since either will do, for xpalloc.
15434 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15435 (xnmalloc, xnrealloc, xpalloc): New functions.
15437 * bidi.c (bidi_shelve_header_size): New constant.
15438 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15439 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15441 * bidi.c (bidi_cache_shrink):
15442 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15444 Don't update size of array until after memory allocation succeeds,
15445 because xmalloc/xrealloc may not return.
15446 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15447 now that we have proper integer overflow checking.
15448 (record_overlay_string, overlay_strings): Catch overflows when
15449 calculating size of overlay_str_buf.
15451 * callproc.c (Fcall_process): Check for size overflow when
15452 calculating size of args2.
15453 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15454 Normally we prefer signed values, but sticking with ptrdiff_t would
15455 require adding more-complicated checks.
15457 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15458 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15459 Redo buffer-overflow calculations to avoid integer overflow.
15460 Add a FIXME comment where memory seems to be over-allocated.
15462 * character.c (Fstring): Check for size-calculation overflow.
15464 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15465 unnecessary integer overflow. Check for size overflow.
15466 (encode_coding_object): Don't update size until xmalloc succeeds.
15468 * composite.c (get_composition_id): Check for overflow in glyph
15469 length calculations.
15471 Integer and memory overflow fixes for display code.
15472 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15473 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15474 (scrolling_window): Check for overflow in size calculations.
15475 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15476 Don't assume glyph table len fits in int.

15478 (row_table_size): Now ptrdiff_t, not int.
15479 (scrolling_window): Avoid overflow in size calculations.
15480 Don't update size until allocation succeeds.
15481 * fns.c (concat): Check for overflow in size calculations.
15482 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15483 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15484 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15486 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15487 (get_doc_string): Check for size calculation overflow.
15488 Don't update size until allocation succeeds.
15489 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15490 EMACS_INT, where ptrdiff_t will do.
15491 (Fsubstitute_command_keys): Check for string overflow.
15493 * editfns.c (set_time_zone_rule): Don't assume environment length
15495 (message_length): Now ptrdiff_t, not int.
15496 (Fmessage_box): Don't update size until allocation succeeds.
15497 Don't assume message length fits in int.
15498 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15500 * emacs.c (main): Do not reallocate argv, since there is a null at
15501 the end that can be overwritten, and this way there's no need to
15502 worry about size-calculation overflow.
15503 (sort_args): Check for size-calculation overflow.
15505 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15507 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15509 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15510 (x_set_scroll_bar_width, x_figure_window_size):
15511 Check for integer overflow.
15512 (x_set_alpha): Do not assume XINT fits in int.
15514 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15515 This is for the members text_lines, text_cols, total_lines, total_cols,
15516 where the system imposes an 'int' limit.
15518 * fringe.c (Fdefine_fringe_bitmap):
15519 Don't update size until alloc works.
15521 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15522 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15524 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15525 Check for size-calculation overflow.
15526 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15527 do, as we prefer signed integers.
15528 (id_to_widget.max_size, id_to_widget.used)
15529 (xg_store_widget_in_map, xg_remove_widget_from_map)
15530 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15531 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15532 Use and return ptrdiff_t, not int.
15533 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15534 * gtkutil.h: Change prototypes to match the above.
15536 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15537 are duplicate now that they've been promoted to lisp.h.
15538 (x_allocate_bitmap_record, x_alloc_image_color)
15539 (make_image_cache, cache_image, xpm_load):
15540 Don't update size until alloc is done.
15541 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15543 Check for size calculation overflow.
15544 (ct_colors_allocated_max): New constant.
15545 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15548 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15549 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15550 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15551 Use ptrdiff_t, not int, to count maps.
15552 (read_char_minibuf_menu_prompt): Check for overflow in size
15553 calculations. Don't update size until allocation succeeds.
15554 Redo calculations to avoid overflow.
15555 * keyboard.h: Change prototypes to match the above.
15557 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15559 (current_minor_maps): Check for size calculation overflow.
15560 * keymap.h: Change prototypes to match the above.
15562 * lread.c (read1, init_obarray): Don't update size until alloc done.
15564 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15565 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15567 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15568 Now ptrdiff_t, not int.
15569 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
15570 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
15572 * process.c (Fnetwork_interface_list): Check for overflow
15573 in size calculation.
15575 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15577 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15578 overflow. Don't bother calling xmalloc when xrealloc will do.

15581 (Fset_match_data): Don't assume list lengths fit in 'int'.
15583 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15584 for command line length. Do not attempt to address one before the
15585 beginning of an array, as that's not portable.
15587 * term.c (max_frame_lines): Remove; unused.
15588 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15590 (encode_terminal_code, calculate_costs): Check for size
15591 calculation overflow.

15593 table lengths and related sizes. Don't update size until alloc
15594 done. Redo calculations to avoid overflow.
15595 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15597 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15598 subtracting pointers.
15599 (gobble_line): Check for overflow more carefully. Don't update size
15602 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15603 Don't update size until alloc done.
15604 Redo size calculations to avoid overflow.
15605 Check for size calculation overflow.
15606 (main) [DEBUG]: Fix typo in invoking tparam1.

15613 Use ptrdiff_t, not int, for sizes.
15614 (Finternal_make_lisp_face, cache_face):
15615 Check for size calculation overflow.
15616 (cache_face): Treat size calculation overflows as if they were
15617 memory exhaustion (the usual treatment), rather than aborting.
15619 * xfns.c (x_encode_text, x_set_name_internal)
15620 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15621 sizes, since they can exceed INT_MAX in size. Check for size
15622 calculation overflow.
15624 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15625 (xg_select): Check for size calculation overflow.
15626 Don't update size until alloc done.
15628 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15629 as sprintf is limited to int lengths.
15631 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15632 (X_LONG_MIN): New macros.
15633 Use them to make the following changes clearer.
15634 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15635 This change doesn't affect the value now, but it may help remind
15636 future maintainers not to raise the value too much later.
15637 (SELECTION_QUANTUM): Remove, replacing with ...
15638 (selection_quantum): ... new function, which avoids overflow.
15640 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15641 assumption that selection length fits in 'int'.
15642 (x_reply_selection_request, x_handle_selection_request)
15643 (x_get_window_property, receive_incremental_selection)
15644 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15645 (lisp_data_to_selection_data, clean_local_selection_data):

15647 (x_reply_selection_request, x_get_window_property)
15648 (receive_incremental_selection, x_property_data_to_lisp):
15649 Redo calculations to avoid overflow.
15650 (x_reply_selection_request): When sending hint, ceiling it at
15651 X_LONG_MAX rather than relying on wraparound overflow to send
15653 (x_get_window_property, receive_incremental_selection)
15654 (lisp_data_to_selection_data, x_property_data_to_lisp):
15655 Check for size-calculation overflow.

15658 Don't store size until memory allocation succeeds.
15659 (x_get_window_property): Plug memory leak on memory exhaustion.
15660 Don't double-block input; malloc is safe here. Don't assume 2**34
15661 - 4 fits in unsigned long. Add an xassert to check
15662 XGetWindowProperty overflow. Be more careful about overflow
15663 calculations, and distinguish size from memory overflow better.
15664 (receive_incremental_selection): When tracing, don't assume
15665 unsigned int is less than INT_MAX.
15666 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15667 harmful) conversions of unsigned short to int.
15668 (lisp_data_to_selection_data): Don't assume that integers
15669 in the range -65535 through -1 fit in an X unsigned short.
15670 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15671 result parameters unless successful. Rely on cons_to_unsigned
15672 to report problems with elements; the old code wasn't right anyway.
15673 (x_check_property_data): Check for int overflow; we cannot use
15674 a wider type due to X limits.
15675 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15677 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15679 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15680 (x_term_init): Check for size calculation overflow.
15681 (x_color_cells): Don't store size until memory allocation succeeds.
15682 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15683 Don't assume alloca size is less than MAX_ALLOCA.
15684 (x_term_init): Don't assume length fits in int (sprintf is limited
15687 Use ptrdiff_t for composition IDs.

15706 * image.c (xpm_get_color_table_h):
15707 * lisp.h (hash_lookup, hash_put):
15708 * minibuf.c (Ftest_completion):
15709 Use ptrdiff_t for hash table indexes, not int (which is too
15710 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15711 32-bit --with-wide-int hosts).
15713 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15714 Add a FIXME comment about memory leaks.
15715 (syms_of_charset): Don't assume xmalloc returns.

15719 * character.h (CHAR_WIDTH):
15720 * indent.c (MULTIBYTE_BYTES_WIDTH):
15721 Use sanitize_char_width to avoid undefined and/or bad behavior
15722 with outlandish widths.
15723 * character.h (sanitize_tab_width): Rename from sanitize_width,
15724 now that we have two such functions. All uses changed.
15725 (sanitize_char_width): New inline function.
15727 Don't assume that tab-width fits in int.
15728 * character.h (sanitize_width): New inline function.
15729 (SANE_TAB_WIDTH): New macro.

15735 * fileio.c: Integer overflow issues with file modes.
15736 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15738 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15739 Remove unreachable code.
15740 (read_hex, load_charset_map_from_file): Check for integer overflow.
15742 * xterm.c: Don't go over XClientMessageEvent limit.
15743 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15744 (x_send_scroll_bar_event): Likewise. Check that the size does not
15745 exceed limits imposed by XClientMessageEvent, as well as the usual
15746 ptrdiff_t and size_t limits.
15748 * keyboard.c: Overflow, signedness and related fixes.
15749 (make_lispy_movement): Use same integer type in forward decl
15750 that is used in the definition.
15751 (read_key_sequence, keyremap_step):
15752 Change bufsize argument back to int, undoing my 2011-03-30 change.
15753 We prefer signed types, and int is wide enough here.
15754 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15755 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15756 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15757 length, not size_t. Use ptrdiff_t for index, not int.
15758 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15759 possibility of integer overflow.
15761 Overflow, signedness and related fixes for images.
15763 * dispextern.h (struct it.stack[0].u.image.image_id)
15764 (struct_it.image_id, struct image.id, struct image_cache.size)

15771 * xdisp.c (calc_pixel_width_or_height):
15772 * xfns.c (image_cache_refcount):
15773 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

15782 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15783 (lookup_image): Remove unnecessary tests.
15784 (xbm_image_p): Locals are now of int, not EMACS_INT,
15785 since parse_image_check makes sure they fit into int.
15786 (png_load, gif_load, svg_load_image):
15787 Prefer int to unsigned where either will do.
15788 (tiff_handler): New function, combining the cores of the
15789 old tiff_error_handler and tiff_warning_handler.
15790 This function is rewritten to use vsnprintf and thereby avoid
15791 stack buffer overflows. It uses only the features of vsnprintf
15792 that are common to both POSIX and native Microsoft.
15793 (tiff_error_handler, tiff_warning_handler): Use it.
15794 (tiff_load, gif_load, imagemagick_load_image):
15795 Don't assume :index value fits in 'int'.
15796 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15797 (imagemagick_load_image): Check that crop parameters fit into
15798 the integer types that MagickCropImage accepts. Don't assume
15799 Vimagemagick_render_type has a nonnegative value. Don't assume
15800 size_t fits in 'long'.
15801 (gs_load): Use printmax_t to print the widest integers possible.
15802 Check for integer overflow when computing image height and width.
15804 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15806 * xdisp.c (redisplay_window): Don't force window start if point
15807 will be invisible in the resulting window. (Bug#9324)

15811 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15812 the display spec is of the form `(space ...)'.
15813 (handle_display_spec): Return the value returned by
15814 handle_single_display_spec, not just 1 or zero.
15815 (handle_single_display_spec): If the display spec is of the form
15816 `(space ...)', and specifies display in the text area, return 2
15818 (try_cursor_movement): Check for the need to scroll more
15819 accurately, and prefer exact match for point under bidi.
15820 Don't advance `row' beyond the last row of the window.
15822 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15823 into disp_prop; all users changed.
15825 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

15837 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15838 buffers, return left-to-right.
15839 (set_cursor_from_row): Consider candidate row a win if its glyph
15840 represents a newline and point is on that newline. Fixes cursor
15841 positioning on the newline at EOL of R2L text within L2R
15842 paragraph, and vice versa.
15843 (try_cursor_movement): Check continued rows, in addition to
15844 continuation rows. Fixes unwarranted scroll when point enters a
15845 continued line of R2L text within an L2R paragraph, or vice versa.
15846 (cursor_row_p): Consider the case of point being equal to
15847 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15848 from the end of a short line to the beginning of a continued line
15849 of R2L text within L2R paragraph.
15850 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15851 composed characters.

15871 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15873 * xdisp.c (redisplay_window): When computing centering_position,
15874 account for the height of the header line. (Bug#8874)
15876 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15877 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15878 candidate is selected by the mouse, and that candidate has a
15879 composed character under the mouse.
15881 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15882 coordinates reported by pos-visible-in-window-p for a composed
15883 character in column zero.
15885 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15887 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15889 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15891 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15892 consider it a hit if to_charpos is anywhere in the range of the
15893 composed buffer positions.
15895 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15897 * image.c (gif_load): Don't assume that each subimage has the same
15898 dimensions as the base image. Handle disposal method that is
15899 "undefined" by the gif spec (Bug#9335).
15901 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15903 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15908 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15909 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15910 from an Org mode buffer to a Speedbar frame.
15912 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15913 a composition, take its buffer position from IT->cmp_it.charpos.
15914 Fixes cursor positioning at the beginning of a line that begins
15915 with a composed character.
15917 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15919 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15920 character bidirectional type, use STRONG_L instead. Fixes crashes
15921 in a buffer produced by `describe-categories'.
15923 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15924 members before the level stack, so they would be saved and
15925 restored when copying iterator state. Fixes incorrect reordering
15926 around TABs covered by display properties.
15928 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

15954 Fix memory allocation problems in Cygwin build (Bug#9273).
15956 * unexcw.c ( __malloc_initialized): Declare external variable.
15957 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15959 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15961 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16000 * xdisp.c (move_it_in_display_line_to): Don't invoke
16001 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16002 ppos_it. Fixes vertical cursor motion when line beginning is
16003 covered by an image. (Bug#9296)
16005 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16007 * nsterm.h (ns_run_ascript): Declare.

16013 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16014 the event loop. Get status from as_status (Bug#7276).
16016 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16017 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16018 the event loop (Bug#7276).
16020 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

16031 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16034 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16036 * xfaces.c (Qframe_set_background_mode): Now static.
16037 * dispextern.h (Qframe_set_background_mode): Remove decl.
16039 * process.c (Fnetwork_interface_info): Declare local only if needed.
16041 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16043 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16044 (Fnetwork_interface_list): Allocate in increments of bytes instead
16045 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16046 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16048 (struct ifflag_def): notrailers is smart on OSX.
16049 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16050 Get hardware address with getifaddrs if available.
16052 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16054 * xdisp.c (iterate_out_of_display_property): xassert that
16055 IT->position is set to within IT->object's boundaries. Break from
16056 the loop as soon as EOB is reached; avoids infloops in redisplay
16057 when IT->position is set up wrongly due to some bug.
16058 Set IT->current to match the bidi iterator unconditionally.
16059 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16060 entry. Force push_it to save on the stack the current
16061 buffer/string position, to be restored by pop_it. Fix flags in
16062 the iterator structure wrt the object coming from a display
16063 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16064 properties. (Bug#9284)
16066 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16068 * fontset.c (fontset_get_font_group): Add proper type checks.
16071 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16073 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16074 and LC_VERSION_MIN_MACOSX.
16075 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16076 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16078 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16080 * xdisp.c (forward_to_next_line_start): Allow to use the
16081 no-display-properties-and-no-overlays under bidi display.
16082 Set disp_pos in the bidi iterator to avoid searches for display
16083 properties and overlays.
16085 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16087 * editfns.c (Fset_time_zone_rule): Document relationship with the
16090 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16091 the font entity extracted from the cache (Bug#8109).
16093 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16095 * composite.c (autocmp_chars): Don't reset point. That is done by
16096 restore_point_unwind (Bug#5984).
16098 2011-08-07 Juri Linkov <juri@jurta.org>
16100 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16101 to show the arg `TIME' instead of `TIMEVAL'.
16103 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16105 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16106 display property strides EOL and includes a newline, as in
16107 longlines-mode. (Bug#9254)
16108 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16109 word-wrap under bidirectional display. (Bug#9224)
16111 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16112 is non-zero, even if the data buffer is NULL. Fixes a crash in
16113 vertical-motion with longlines-mode. (Bug#9254)
16115 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16117 * bidi.c <bidi_cache_total_alloc>: Now static.
16118 (bidi_initialize): Initialize bidi_cache_total_alloc.
16120 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16123 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16124 amount allocated this far in `bidi_cache_total_alloc'.
16125 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16126 non-zero, only free the data buffer without restoring the cache
16127 contents. All callers changed.
16129 * dispextern.h (bidi_unshelve_cache): Update prototype.
16131 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16132 (move_it_in_display_line, move_it_to)
16133 (move_it_vertically_backward, move_it_by_lines): Replace the call
16134 to xfree to an equivalent call to bidi_unshelve_cache.
16135 (move_it_in_display_line_to): Fix logic of returning
16136 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16138 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16140 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16141 came from a string character with a `cursor' property. (Bug#9229)
16143 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16145 * Makefile.in (LIB_PTHREAD): New variable.
16146 (LIBES): Add LIB_PTHREAD (Bug#9216).
16148 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16149 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16151 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16153 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16155 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16157 * xterm.c (x_find_topmost_parent): New function.
16158 (x_set_frame_alpha): Find topmost parent window with
16159 x_find_topmost_parent and set the property there also (bug#9181).
16160 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16162 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16164 * callproc.c (Fcall_process): Avoid vfork clobbering
16165 the local vars buffer, coding_systems, current_dir.
16167 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16169 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16171 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16173 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16174 so that it is not optimized away.
16176 * xdisp.c (compute_display_string_pos): Remove unused local.
16178 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16180 Fix slow cursor motion and scrolling in large buffers with
16181 selective display, like Org Mode buffers. (Bug#9218)
16183 * dispextern.h (struct bidi_it): New member disp_prop_p.
16185 * xdisp.c: Remove one-slot cache of display string positions.
16186 (compute_display_string_pos): Accept an additional argument
16187 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16188 for a display string or property. If found, set DISP_PROP_P
16191 * bidi.c (bidi_fetch_char): Accept an additional argument
16192 DISP_PROP_P, and pass it to compute_display_string_pos.
16193 Only handle text covered by a display string if DISP_PROP_P is returned
16194 non-zero. All callers of bidi_fetch_char changed.
16196 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16198 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16200 2010-12-03 Don March <don@ohspite.net>
16202 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16203 last character M-[char] is translated to ESC [char] (bug#7541).
16205 2011-08-02 Kenichi Handa <handa@m17n.org>
16207 * lisp.h (uniprop_table): Extern it.
16209 * chartab.c (uniprop_table): Make it non-static.
16211 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16213 * xdisp.c (forward_to_next_line_start): Accept additional argument
16214 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16216 (reseat_at_next_visible_line_start): Use the bidi iterator state
16217 returned by forward_to_next_line_start to restore the state of
16218 it->bidi_it after backing up to previous newline. (Bug#9212)
16220 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16222 * regex.c (re_comp): Protoize.
16223 (re_exec): Fix return type.
16224 (regexec): Fix type of `ret'. (Bug#9203)
16226 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16228 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16229 This is needed if max-image-size is a floating-point number.
16231 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16233 * print.c (print_object): Print empty symbol as ##.
16235 * lread.c (read1): Read ## as empty symbol.
16237 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16239 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16240 setting frame foreground color (Bug#9175).
16241 (x_set_background_color): Likewise.
16243 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16244 contents (Bug#9176).
16245 (EmacsTooltip -init): Remove bezels and add shadows to
16248 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16249 or scroll bar (Bug#8470).
16251 * nsfont.m (nsfont_open): Remove assignment to voffset and
16252 unnecessary vars hshink, expand, hd, full_height, min_height.
16253 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16255 * nsterm.h (nsfont_info): Remove voffset field.
16257 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16259 Implement strike-through and overline on NextStep (Bug#8863).
16261 * nsfont.m (nsfont_open): Use underline position provided by font,
16262 instead of hard-coded value of 2.
16263 (nsfont_draw): Call ns_draw_text_decoration instead.
16265 * nsterm.h: Add declaration for ns_draw_text_decoration.
16267 * nsterm.m (ns_draw_text_decoration): New function for drawing
16268 underline, overline, and strike-through.
16269 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16270 ns_draw_text_decoration. Change treatment of cursor drawing to
16271 accommodate underlining, etc.
16273 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16275 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16278 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16280 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16281 Without this fix, if a signal arrives just after memory fills up,
16282 'malloc' might be invoked reentrantly.
16284 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16285 In other words, assume that every image size is allowed, on non-X
16286 hosts. This assumption is probably wrong, but it lets Emacs compile.
16288 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16290 * regex.c (re_iswctype): Convert return values to boolean.
16292 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16294 * xdisp.c (compute_display_string_pos): Don't use cached display
16295 string position if the buffer had its restriction changed.
16298 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16300 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16302 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16304 Integer signedness and overflow and related fixes. (Bug#9079)
16306 * bidi.c: Integer size and overflow fixes.
16307 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16308 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16309 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16310 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16311 (bidi_find_other_level_edge):
16312 Use ptrdiff_t instead of EMACS_INT where either will do.
16313 This works better on 32-bit hosts configured --with-wide-int.
16314 (bidi_cache_ensure_space): Check for size-calculation overflow.
16315 Use % rather than repeated addition, for better worst-case speed.
16316 Don't set bidi_cache_size until after xrealloc returns, because it
16318 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16319 (bidi_cache_ensure_space): Also check that the bidi cache size
16320 does not exceed that of the largest Lisp string or buffer. See Eli
16321 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16323 * alloc.c (__malloc_size_t): Remove.
16324 All uses replaced by size_t. See Andreas Schwab's note
16325 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16327 * image.c: Improve checking for integer overflow.
16328 (check_image_size): Assume that f is nonnull, since
16329 it is always nonnull in practice. This is one less thing to
16330 worry about when checking for integer overflow later.
16331 (x_check_image_size): New function, which checks for integer
16332 overflow issues inside X.
16333 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16334 This removes the need for a memory_full check.
16335 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16336 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16337 (xbm_read_bitmap_data): Change locals back to 'int', since
16338 their values must fit in 'int'.
16339 (xpm_load_image, png_load, tiff_load):
16340 Invoke x_create_x_image_and_pixmap earlier,
16341 to avoid much needless work if the image is too large.
16342 (tiff_load): Treat overly large images as if
16343 x_create_x_image_and_pixmap failed, not as malloc failures.
16344 (gs_load): Use x_check_image_size.
16346 * gtkutil.c: Omit integer casts.
16347 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16348 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16350 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16352 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16353 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16354 would wrongly return t on a 64-bit host.
16356 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16357 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16358 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16359 and therefore cause GCC to emit a bogus diagnostic in some cases.
16361 * image.c: Integer signedness and overflow and related fixes.
16362 This is not an exhaustive set of fixes, but it's time to
16363 record what I've got.
16364 (lookup_pixel_color, check_image_size): Remove redundant decls.
16365 (check_image_size): Don't assume that arbitrary EMACS_INT values
16366 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16367 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16368 (tiff_load, imagemagick_load_image):
16369 Check for overflow in size calculations.
16370 (x_create_x_image_and_pixmap): Remove unnecessary test for
16371 xmalloc returning NULL; that can't happen.
16372 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16373 (xpm_color_bucket): Use better integer hashing function.
16374 (xpm_cache_color): Don't possibly over-allocate memory.
16375 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16376 (gif_memory_source):
16377 Use ptrdiff_t, not int or size_t, to record sizes.
16378 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16379 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16380 either works, as we prefer signed integers.
16381 (tiff_read_from_memory, tiff_write_from_memory):
16382 Return tsize_t, not size_t, since that's what the TIFF API wants.
16383 (tiff_read_from_memory): Don't fail simply because the read would
16384 go past EOF; instead, return a short read.
16385 (tiff_load): Omit no-longer-needed casts.
16386 (Fimagemagick_types): Don't assume size fits into 'int'.
16388 Improve hashing quality when configured --with-wide-int.
16389 * fns.c (hash_string): New function, taken from sxhash_string.
16390 Do not discard information about ASCII character case; this
16391 discarding is no longer needed.
16392 (sxhash-string): Use it. Change sig to match it. Caller changed.
16393 * lisp.h: Declare it.
16394 * lread.c (hash_string): Remove, since we now use fns.c's version.
16395 The fns.c version returns a wider integer if --with-wide-int is
16396 specified, so this should help the quality of the hashing a bit.
16398 * emacs.c: Integer overflow minor fix.
16399 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16400 Define only if GNU_LINUX.
16401 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16403 * dispnew.c: Integer signedness and overflow fixes.
16404 Remove unnecessary forward decls, that were a maintenance hassle.
16405 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16407 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16408 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16409 (prepare_desired_row, line_draw_cost):
16410 Use int, not unsigned, where either works.
16411 (save_current_matrix, restore_current_matrix):
16412 Use ptrdiff_t, not size_t, where either works.
16413 (init_display): Check for overflow more accurately, and without
16414 relying on undefined behavior.
16416 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16417 Remove, replacing with the new symbols in lisp.h. All uses changed.
16418 * fileio.c (make_temp_name):
16419 * filelock.c (lock_file_1, lock_file):
16420 * xdisp.c (message_dolog):
16421 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16422 Use pMd etc. instead.
16423 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16424 replacing the pWIDE etc. symbols removed from editfns.c.
16426 * keyboard.h (num_input_events): Now uintmax_t.
16427 This is (very slightly) less likely to mess up due to wraparound.
16430 * buffer.c: Integer signedness fixes.
16431 (alloc_buffer_text, enlarge_buffer_text):
16432 Use ptrdiff_t rather than size_t when either will do, as we prefer
16435 * alloc.c: Integer signedness and overflow fixes.
16436 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16437 (__malloc_size_t): Default to size_t, not to int.
16438 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16439 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16440 Prefer ptrdiff_t to size_t when either would do, as we prefer
16442 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16443 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16444 Now const. Initialize with values that are in range even if char
16446 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16447 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16448 These functions do the right thing with sizes > 2**32.
16449 (check_depth): Now ptrdiff_t, not int.
16450 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16451 Adjust to new way of storing sizes. Check for size overflow bugs
16453 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16454 slightly wrong anyway, as it missed one instance of
16455 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16456 (refill_memory_reserve): Omit needless cast to size_t.
16457 (mark_object_loop_halt): Mark as externally visible.
16459 * xselect.c: Integer signedness and overflow fixes.
16460 (Fx_register_dnd_atom, x_handle_dnd_message):
16461 Use ptrdiff_t, not size_t, since we prefer signed.
16462 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16463 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16464 x_dnd_atoms_size and x_dnd_atoms_length.
16466 * doprnt.c: Prefer signed to unsigned when either works.
16468 * doprnt.c (doprnt):
16470 * xdisp.c (vmessage):
16471 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16472 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16473 prefer signed arithmetic to avoid comparison confusion.
16474 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16475 but is a bit tricky.
16477 Assume freestanding C89 headers, string.h, stdlib.h.
16478 * data.c, doprnt.c, floatfns.c, print.c:
16479 Include float.h unconditionally.
16480 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16481 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16482 * regex.c: Likewise for stddef.h, string.h.
16483 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16484 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16485 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16486 (STDC_HEADERS): Remove obsolete defines.
16487 * sysdep.c: Include limits.h unconditionally.
16489 Assume support for memcmp, memcpy, memmove, memset.
16490 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16491 * regex.c (memcmp, memcpy):
16492 Remove; we assume C89 now.
16494 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16495 (__malloc_safe_bcopy): Remove; no longer needed.
16497 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16498 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16499 well either way, and we prefer signed to unsigned.
16501 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16503 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16504 closes the connection while we're reading (bug#9182).
16506 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16508 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16509 are specified (Bug#9168).
16511 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16513 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16514 Found by GCC static checking and --with-wide-int on a 32-bit host.
16516 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16518 * xdisp.c (compute_display_string_pos): Fix logic of caching
16519 previous display string position. Initialize cached_prev_pos to
16520 -1. Fixes slow-down at the beginning of a buffer.
16522 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16524 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16525 for attrs[LFACE_FONTSET_INDEX].
16527 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16529 * xml.c (parse_region): Remove unused local
16530 that was recently introduced.
16532 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16534 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16535 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16537 * xdisp.c (move_it_in_display_line_to): Record the best matching
16538 position for TO_CHARPOS while scanning the line, and restore it on
16539 exit if none of the characters scanned was an exact match.
16540 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16541 when exact match is impossible due to invisible text, and the
16542 lines are truncated.
16544 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16546 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16549 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16551 Fix a significant slow-down of cursor motion with C-n, C-p,
16552 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16553 auto-repeat under bidi redisplay in fontified buffers.
16554 * xdisp.c (compute_stop_pos_backwards): New function.
16555 (next_element_from_buffer): Call compute_stop_pos_backwards to
16556 find a suitable prev_stop when we find ourselves before
16558 (reseat): Don't look for prev_stop, as that could mean a very long
16560 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16561 <cached_disp_overlay_modiff>: Cache for last found display string
16563 (compute_display_string_pos): Return the cached position if asked
16564 about the same buffer in the same area of character positions, and
16565 the buffer wasn't changed since the time the display string
16566 position was cached.
16568 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16570 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16571 is an integer, which is important for empty lines. (Bug#9149)
16573 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16575 * frame.c (Fmodify_frame_parameters): In tty case, update the
16576 default face if necessary (Bug#4238).
16578 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16580 * editfns.c (Fstring_to_char): No need to explain what a character
16581 is in the docstring (Bug#6576).
16583 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16585 * xml.c (parse_region): Make sure we always return a tree.
16587 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16589 * xml.c (parse_region): If a document contains only comments,
16592 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16594 * xml.c (make_dom): Return comments, too.
16596 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16599 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16600 and the surrounding thread.
16601 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16602 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16603 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16605 * s/openbsd.h (BROKEN_SIGIO): Define.
16606 * unexelf.c (unexec) [__OpenBSD__]:
16607 Don't update the .mdebug section of the Alpha COFF symbol table.
16609 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16611 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16614 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16616 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16617 This fixes some race conditions on the permissions of any newly
16620 * alloc.c (valid_pointer_p): Use pipe, not open.
16621 This fixes some permissions issues when debugging.
16623 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16624 If fchown fails to set both uid and gid, try to set just gid,
16625 as that is sometimes allowed. Adjust the file's mode to eliminate
16626 setuid or setgid bits that are inappropriate if fchown fails.
16628 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16630 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16631 to compare Lisp_Objects.
16632 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16633 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16634 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16636 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16638 * lread.c (read_integer): Unread even EOF character.
16639 (read1): Likewise. Properly record start position of symbol.
16641 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16642 symbol character follows.
16644 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16646 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16647 This works around a problem with the previous change to Fcopy_file.
16648 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16649 and without this change, GCC might complain about discarding
16650 fchown's return value.
16652 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16654 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16656 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16658 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16660 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16662 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16663 it's used from the C level.
16665 * process.c: Use the same condition for POLL_FOR_INPUT in both
16666 keyboard.c and process.c (bug#1858).
16668 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16670 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16671 (Fgnutls_boot): Use it.
16673 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16675 * doc.c (Fsubstitute_command_keys): Revert last change.
16677 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16679 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16680 quotes the next character, and doesn't affect other longer
16681 sequences (bug#8935).
16683 * lread.c (syms_of_lread): Clarify that is isn't only
16684 `eval-buffer' and `eval-defun' that's affected by
16685 `lexical-binding' (bug#8460).
16687 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16689 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16690 bidi redisplay when a line includes both an image and is truncated.
16692 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16694 Fix minor problems found by static checking.
16695 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16696 (elsz): Now a signed constant, not a size_t var. We prefer signed
16697 types to unsigned, to avoid integer comparison confusion. Without
16698 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16699 "cannot optimize loop, the loop counter may overflow", a symptom
16701 * indent.c (Fvertical_motion): Mark locals as initialized.
16702 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16704 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16706 * search.c (Fre_search_backward): Mention `case-fold-search' in
16707 all the re_search_* functions (bug#8138).

16722 bidi_it->string.schars.
16723 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to

16727 buffer position was specified. Initialize paragraph_embedding to
16729 (reseat_to_string): Initialize the bidi iterator.
16730 (display_string): If we need to ignore text properties of
16731 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16732 original value of -1 will not work with bidi.)
16733 (compute_display_string_pos): First arg is now struct
16734 `text_pos *'; all callers changed. Support display properties on
16736 (compute_display_string_end): Support display properties on Lisp
16738 (init_iterator, reseat_1, reseat_to_string): Initialize the
16739 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16740 when iterating on a string not from display properties).
16741 (compute_display_string_pos, compute_display_string_end):
16742 Fix calculation of the object to scan. Fixes an error when using
16744 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16745 base_level_stop; instead, set base_level_stop to BEGV.
16746 Fixes crashes in vertical-motion.
16747 (next_element_from_buffer): Improve commentary for when
16748 the iterator is before prev_stop.
16749 (init_iterator): Initialize bidi_p from the default value of
16750 bidi-display-reordering, not from buffer-local value. Use the
16751 buffer-local value only if initializing for buffer iteration.
16752 (handle_invisible_prop): Support invisible properties on strings
16753 that are being bidi-reordered.
16754 (set_iterator_to_next): Support bidi reordering of C strings and
16756 (next_element_from_string): Support bidi reordering of Lisp

16760 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16761 (init_iterator): Don't initialize it->bidi_p for strings
16763 (reseat_to_string): Initialize it->bidi_p for strings here.
16764 (next_element_from_string, next_element_from_c_string)
16765 (next_element_from_buffer): Add xassert's for correspondence

16770 character that is not the first one in the visual order.
16771 (get_visually_first_element): New function, refactored from common
16772 parts of next_element_from_buffer, next_element_from_string, and
16773 next_element_from_c_string.
16774 (tool_bar_lines_needed, redisplay_tool_bar)
16775 (display_menu_bar): Force left-to-right direction. Add a FIXME
16776 comment for making that be controlled by a user option.
16777 (push_it, pop_it): Save and restore the state of the
16778 bidi iterator. Save and restore the bidi_p flag.
16779 (pop_it): Iterate out of display property for string iteration as
16781 (iterate_out_of_display_property): Support iteration over strings.
16782 (handle_single_display_spec): Set up it->bidi_it for iteration
16783 over a display string, and call bidi_init_it.
16784 (handle_single_display_spec, next_overlay_string)
16785 (get_overlay_strings_1, push_display_prop): Set up the bidi
16786 iterator for displaying display or overlay strings.
16787 (forward_to_next_line_start): Don't use the shortcut if
16789 (back_to_previous_visible_line_start): If handle_display_prop
16790 pushed the iterator stack, restore the internal state of the bidi
16791 iterator by calling bidi_pop_it same number of times.
16792 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16793 and we are bidi-iterating, don't decrement the iterator position;
16794 instead, set the first_elt flag in the bidi iterator, to produce
16796 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16797 (push_display_prop): xassert that we are iterating a buffer.
16798 (push_it, pop_it): Save and restore paragraph_embedding member.
16799 (handle_single_display_spec, next_overlay_string)
16800 (get_overlay_strings_1, reseat_1, reseat_to_string)
16801 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16802 correctly. Don't assume unibyte strings are not bidi-reordered.
16803 (compute_display_string_pos)
16804 (compute_display_string_end): Fix handling the case of C string.
16805 (push_it, pop_it): Save and restore from_disp_prop_p.

16810 popping after iteration over a string that came from a display
16811 property. Fix a typo in popping stretch info. Add an assertion
16812 for verifying that the iterator position is in sync with the bidi
16814 (handle_single_display_spec, get_overlay_strings_1)
16815 (push_display_prop): Fix initialization of paragraph direction for
16816 string when that of the parent object is not yet determined.

16818 iterator with IT's position. (Bug#7616)
16819 (find_row_edges): If ROW->start.pos gives position
16820 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

16822 Reset the from_disp_prop_p flag.
16823 (SAVE_IT, RESTORE_IT): New macros.

16828 (try_scrolling, redisplay_window, display_line): Use them when
16829 saving a temporary copy of the iterator and restoring it back.
16830 (back_to_previous_visible_line_start, reseat_1)
16831 (init_iterator): Empty the bidi cache "stack".
16832 (move_it_in_display_line_to): If iterator ended up at
16833 EOL, but we never saw any buffer positions smaller than
16834 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16835 motion in bidi-reordered lines.

16837 immediately before the call to set_iterator_to_next. Fixes cursor
16838 motion in bidi-reordered lines with stretch glyphs and strings
16839 displayed in margins. (Bug#8133) (Bug#8867)
16840 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16842 (pos_visible_p): Support positions in bidi-reordered lines.
16843 Save and restore bidi cache.
16845 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16846 (bidi_paragraph_info): Delete unused struct.
16847 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16848 (bidi_cache_start): New variable.

16864 Support iteration over a string.
16865 (bidi_set_sor_type, bidi_resolve_explicit_1)
16866 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16867 can now be zero (for strings); special values 0 and -1 were
16868 changed to -1 and -2, respectively.
16869 (bidi_char_at_pos): New function.
16870 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16898 * dispextern.h (struct bidi_string_data): New structure.
16899 (struct bidi_it): New member `string'. Make flag members be 1-bit

16956 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16958 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16959 The old code sometimes used this field without initializing it.
16961 * alloc.c (gc_sweep): Don't read past end of array.
16962 In theory, the old code could also have corrupted Emacs internals,
16963 though it'd be very unlikely.

17226 (clone_per_buffer_values): Don't assume that

17228 This isn't true in general, and it's particularly not true
17229 if Emacs is configured with --with-wide-int.
17230 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17231 New macros, used in the buffer.c change.

17267 Random fixes. E.g., (random) never returned negative values.
17268 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17269 subseconds part to the entropy, as that's a bit more random.
17270 Prefer signed to unsigned, since the signedness doesn't matter and
17271 in general we prefer signed. When given a limit, use a
17272 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17273 latter isn't right if USE_2_TAGS_FOR_INTS.
17274 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17275 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17287 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17288 This is more efficient than Ffile_directory_p and avoids a minor race.
17290 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17292 * buffer.c (Foverlay_put): Say what the return value is
17295 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17296 is a directory before asking whether to use the file name

17299 error be more correct.
17301 * fns.c (Frequire): Remove the mention of the .gz files, since
17302 that's installation-specific, but keep the mention of

17315 Qgnutls_bootprop_verify_error (which is no longer used).
17317 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17318 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17319 Also (re)move comments that are misplaced or no longer relevant.

17348 * lread.c (syms_of_lread): Mention single symbols defined by
17349 `defvar' or `defconst' (bug#7154).
17351 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17352 (Frequire): Mention get-load-suffixes.

17420 * eval.c (struct backtrace): Simplify and port the data structure.
17421 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17422 signed bit field, as this assumption is not portable and it makes
17423 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17424 "char debug_on_exit : 1" as this is not portable either; instead,
17425 use the portable "unsigned int debug_on_exit : 1". Remove unused
17426 member evalargs. Remove obsolete comments about cc bombing out.
17428 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17500 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17501 and use min_width/height from frames size_hint to set
17502 min_width/height (Bug#8919).

17595 (PRINTPREPARE, printchar, strout):
17596 Don't set size unless allocation succeeds.
17598 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17599 for sizes. Check for string overflow more accurately.

17603 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17604 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17610 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17612 * lread.c: Integer overflow fixes.
17613 (read_integer): Radix is now EMACS_INT, not int,
17614 to improve quality of diagnostics for out-of-range radices.
17615 Calculate buffer size correctly for out-of-range radices.
17616 (read1): Check for integer overflow in radices, and in
17617 read-circle numbers.
17618 (read_escape): Avoid int overflow.
17619 (Fload, openp, read_buffer_size, read1)
17620 (substitute_object_recurse, read_vector, read_list, map_obarray):

17636 2011-06-22 Leo Liu <sdl.web@gmail.com>
17638 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17639 Move to minibuffer.el.
17641 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17643 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17644 The following patches are for when GLYPH_DEBUG && !XASSERT.
17645 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17646 * dispnew.c (flush_stdout):
17647 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17648 Mark as externally visible.
17649 * dispnew.c (check_window_matrix_pointers): Now static.

17658 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17660 (debug_method_add): Use va_list and vsprintf rather than relying
17661 on undefined behavior with wrong number of arguments.
17662 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17663 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17664 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17665 since we're not interested in debugging glyphs with old libraries.
17666 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17667 GCC 4.6.0's static checking.
17669 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17688 (.bitmaps_last, struct x_output.icon_bitmap):
17689 Use ptrdiff_t, not int, for bitmap indexes.

17704 (overlays_at, overlays_in): Check for size-calculation overflow.
17706 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17708 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17709 (x_session_initialize): Do not assume string length fits in int.
17711 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17712 This is unlikely, but can occur if DPI is outlandish.
17714 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17715 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

17731 (display_mode_element): Don't assume strlen fits in int.
17733 * termcap.c: Don't assume sizes fit in int and never overflow.

17737 * minibuf.c (Fread_buffer):
17738 * lread.c (intern, intern_c_string):
17739 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17757 Don't assume pid_t and time_t fit in unsigned long.
17758 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17759 (current_lock_owner): Prefer signed type for sizes.
17760 Use memcpy, not strncpy, where memcpy is what is really wanted.
17761 Don't assume (via atoi) that time_t and pid_t fit in int.
17762 Check for time_t and/or pid_t out of range, e.g., via a network share.
17763 Don't alloca where an auto var works fine.
17765 * fileio.c: Fix some integer overflow issues.

17790 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17792 * lread.c (invalid_syntax): Omit length argument.
17793 All uses changed. This doesn't fix a bug, but it simplifies the
17794 code away from its former Hollerith-constant appearance, and it's
17795 one less 'int' to worry about when looking at integer-overflow issues.
17796 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17798 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17799 This didn't break anything, but it didn't help either.
17800 It's confusing to put a bogus integer in a place where the actual
17801 value does not matter.
17802 (LIST_END_P): Remove unused macro and its bogus comment.
17803 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17805 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17806 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17808 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17809 We prefer signed types, and the value cannot exceed the EMACS_INT
17810 range anyway (because otherwise the length would not be representable).
17811 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17812 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17813 This avoids a GCC warning when WIDE_EMACS_INT.
17815 * indent.c (sane_tab_width): New function.
17816 (current_column, scan_for_column, Findent_to, position_indentation)
17817 (compute_motion): Use it. This is just for clarity.
17818 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17820 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17822 * lisp.h (lint_assume): New macro.
17823 * composite.c (composition_gstring_put_cache):
17824 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17826 * editfns.c, insdel.c:
17827 Omit unnecessary forward decls, to simplify future changes.
17829 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17831 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17833 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17834 Use much-faster test for byte-length change.
17835 Don't assume string byte-length fits in 'int'.
17836 Check that character arg fits in 'int'.
17837 (mapcar1): Declare byte as byte, for clarity.
17839 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17841 * fns.c (concat): Catch string overflow earlier.
17842 Do not rely on integer wraparound.
17844 * dispextern.h (struct it.overlay_strings_charpos)
17845 (struct it.selective): Now EMACS_INT, not int.
17846 * xdisp.c (forward_to_next_line_start)
17847 (back_to_previous_visible_line_start)
17848 (reseat_at_next_visible_line_start, next_element_from_buffer):
17849 Don't arbitrarily truncate the value of 'selective' to int.
17851 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17853 * composite.c: Don't truncate sizes to 'int'.
17854 (composition_gstring_p, composition_reseat_it)
17855 (composition_adjust_point): Use EMACS_INT, not int.
17856 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17857 not EMACS_UINT, for indexes.
17859 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17861 * buffer.c: Include <verify.h>.
17862 (struct sortvec.priority, struct sortstr.priority):
17863 Now EMACS_INT, not int.
17864 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17865 (struct sortstr.size, record_overlay_string)
17866 (struct sortstrlist.size, struct sortlist.used):
17867 Don't truncate size to int.
17868 (record_overlay_string): Check for size-calculation overflow.
17869 (init_buffer_once): Check at compile-time, not run-time.
17871 2011-06-22 Jim Meyering <meyering@redhat.com>
17873 Don't leak an XBM-image-sized buffer
17874 * image.c (xbm_load): Free the image buffer after using it.
17876 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17879 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17880 that Sun C diagnosed.
17881 * fns.c (secure_hash): Fix pointer signedness issue.
17882 * intervals.c (static_offset_intervals): New function.
17883 (offset_intervals): Use it.
17885 2011-06-21 Leo Liu <sdl.web@gmail.com>
17888 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17891 * fns.c (secure_hash): Rename from crypto_hash_function and change
17892 the first arg to accept symbols.
17893 (Fsecure_hash): New primitive.
17894 (syms_of_fns): New symbols.
17896 2011-06-20 Deniz Dogan <deniz@dogan.se>
17898 * process.c (Fset_process_buffer): Clarify return value in
17901 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17903 * dispnew.c (add_window_display_history): Use BVAR.
17905 * xdisp.c (debug_method_add): Use BVAR.
17906 (check_window_end, dump_glyph_matrix, dump_glyph)
17907 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17909 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17912 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17913 check till after the cache is created in init_frame_faces.
17915 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17917 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17919 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17921 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17922 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17923 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17925 Improve buffer-overflow checking (Bug#8873).
17926 * fileio.c (Finsert_file_contents):
17927 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17928 Remove the old (too-loose) buffer overflow checks.
17929 They weren't needed, since make_gap checks for buffer overflow.
17930 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17931 The old code merely checked for Emacs fixnum overflow, and relied
17932 on undefined (wraparound) behavior. The new code avoids undefined
17933 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17935 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17936 Tune. Don't use wider integers than needed. Don't use alloca.
17937 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17939 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17941 * insdel.c, lisp.h (buffer_overflow): New function.
17942 (insert_from_buffer_1, replace_range, replace_range_2):
17943 * insdel.c (make_gap_larger):
17944 * editfns.c (Finsert_char):
17945 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17947 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17949 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17951 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17953 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17954 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17956 * fileio.c: Don't assume EMACS_INT fits in off_t.
17957 (emacs_lseek): New static function.
17958 (Finsert_file_contents, Fwrite_region): Use it.
17959 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17961 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17963 * fns.c: Don't overflow int when computing a list length.
17964 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17965 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17966 truncation on 64-bit hosts. Check for QUIT every
17967 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17968 faster and is responsive enough.
17969 (Flength): Report an error instead of overflowing an integer.
17970 (Fsafe_length): Return a float if the value is not representable
17971 as a fixnum. This shouldn't happen except in contrived situations.
17972 (Fnthcdr, Fsort): Don't assume list length fits in int.
17973 (Fcopy_sequence): Don't assume vector length fits in int.
17975 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17976 (header_size, word_size): New constants.
17977 (allocate_vectorlike): Don't check size overflow here.
17978 (allocate_vector): Check it here instead, since this is the only
17979 caller of allocate_vectorlike that could cause overflow.
17980 Check that the new vector's length is representable as a fixnum.
17982 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17983 The previous code was bogus. For example, next_almost_prime (32)
17984 returned 39, which is undesirable as it is a multiple of 3; and
17985 next_almost_prime (24) returned 25, which is a multiple of 5 so
17986 why was the code bothering to check for multiples of 7?
17988 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17990 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17992 Variadic C functions now count arguments with ptrdiff_t.
17993 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17994 Back then I didn't know that the Emacs coding style prefers signed int.
17995 Also, in the meantime I found a few more instances where arguments
17996 were being counted with int, which may truncate counts on 64-bit
17997 machines, or EMACS_INT, which may be unnecessarily wide.
17998 * lisp.h (struct Lisp_Subr.function.aMANY)
17999 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18000 Arg counts are now ptrdiff_t, not size_t.
18001 All variadic functions and their callers changed accordingly.
18002 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18003 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18004 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18005 * callint.c (Fcall_interactively): Check arg count for overflow,
18006 to avoid potential buffer overrun. Use signed char, not 'int',
18007 for 'varies' array, so that we needn't bother to check its size
18008 calculation for overflow.
18009 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18010 * eval.c (apply_lambda):
18011 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18012 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18013 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18015 * callint.c (Fcall_interactively): Don't use index var as event count.
18017 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18018 * mem-limits.h (SIZE): Remove; no longer used.
18020 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18022 Remove unnecessary casts.
18023 * xterm.c (x_term_init):
18024 * xfns.c (x_set_border_pixel):
18025 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18026 These aren't needed now that we assume ANSI C.
18028 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18029 It's more likely to cause problems (due to unsigned overflow)
18032 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18034 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18036 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18038 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18040 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18042 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18044 GLYPH_CODE_FACE returns EMACS_INT, not int.
18045 * dispextern.h (merge_faces):
18046 * xfaces.c (merge_faces):
18047 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18048 Don't assume EMACS_INT fits in int.
18050 * character.h (CHAR_VALID_P): Remove unused parameter.
18051 * fontset.c, lisp.h, xdisp.c: All uses changed.
18053 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18055 * fns.c (concat): Minor tuning based on overflow analysis.
18056 This doesn't fix any bugs. Use int to hold character, instead
18057 of constantly refetching from Emacs object. Use XFASTINT, not
18058 XINT, for value known to be a character. Don't bother comparing
18059 a single byte to 0400, as it's always less.
18061 * floatfns.c (Fexpt):
18062 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18064 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18067 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18069 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18070 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18071 incorrectly succeed when S was a string, because 4294967386 was
18072 truncated before it was used.
18074 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18075 Otherwise, an out-of-range integer could cause undefined behavior
18078 * composite.c: Use int, not EMACS_INT, for characters.
18079 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18080 EMACS_INT, for values that are known to be in character range.
18081 This doesn't fix any bugs but is the usual style inside Emacs and
18082 may generate better code on 32-bit machines.
18084 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18085 This is for reasons similar to the recent CHAR_STRING fix.
18086 * charset.c (Fencode_char): Check that character arg is actually
18087 a character. Pass an int to ENCODE_CHAR.
18088 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18089 wider than 'int', as a compile-time check to prevent future regressions
18092 * character.c (char_string): Remove unnecessary casts.
18094 Make sure a 64-bit char is never passed to CHAR_STRING.
18095 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18096 by silently ignoring the top 32 bits, allowing some values
18097 that were far too large to be valid characters.
18098 * character.h: Include <verify.h>.
18099 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18100 arguments are no wider than unsigned, as a compile-time check
18101 to prevent future regressions in this area.
18103 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18104 (Fsubst_char_in_region):
18106 * xdisp.c (decode_mode_spec_coding):
18107 Adjust to CHAR_STRING's new requirement.
18108 * editfns.c (Finsert_char, Fsubst_char_in_region):
18109 * fns.c (concat): Check that character args are actually
18110 characters. Without this test, these functions did the wrong
18111 thing with wildly out-of-range values on 64-bit hosts.
18113 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18114 These casts should not be needed on 32-bit hosts, either.
18115 * keyboard.c (read_char):
18116 * lread.c (Fload): Remove casts to unsigned.
18118 * lisp.h (UNSIGNED_CMP): New macro.
18119 This fixes comparison bugs on 64-bit hosts.
18120 (ASCII_CHAR_P): Use it.
18121 * casefiddle.c (casify_object):
18122 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18123 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18124 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18125 * dispextern.h (FACE_FROM_ID):
18126 * keyboard.c (read_char): Use UNSIGNED_CMP.
18128 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18129 not to EMACS_INT, to avoid GCC warning.
18131 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18133 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18134 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18135 isn't needed on 32-bit machines.
18137 * buffer.c (Fgenerate_new_buffer_name):
18138 Use EMACS_INT for count, not int.
18139 (advance_to_char_boundary): Return EMACS_INT, not int.
18141 * data.c (Qcompiled_function): Now static.
18143 * window.c (window_body_lines): Now static.
18145 * image.c (gif_load): Rename local to avoid shadowing.
18147 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18148 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18149 * alloc.c (make_save_value): Integer argument is now of type
18150 ptrdiff_t, not int.
18151 (mark_object): Use ptrdiff_t, not int.
18152 * lisp.h (pD): New macro.
18153 * print.c (print_object): Use it.
18155 * alloc.c: Use EMACS_INT, not int, to count objects.
18156 (total_conses, total_markers, total_symbols, total_vector_size)
18157 (total_free_conses, total_free_markers, total_free_symbols)
18158 (total_free_floats, total_floats, total_free_intervals)
18159 (total_intervals, total_strings, total_free_strings):
18160 Now EMACS_INT, not int. All uses changed.
18161 (Fgarbage_collect): Compute overall total using a double, so that
18162 integer overflow is less likely to be a problem. Check for overflow
18163 when converting back to an integer.
18164 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18165 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18166 These were 'int' variables that could overflow on 64-bit hosts;
18167 they were never used, so remove them instead of repairing them.
18168 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18169 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18170 Previously, this ceilinged at INT_MAX, but that doesn't work on
18172 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18174 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18175 (allocate_vectorlike): Check for ptrdiff_t overflow.
18176 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18177 when a (possibly-narrower) signed value would do just as well.
18178 We prefer using signed arithmetic, to avoid comparison confusion.
18180 * alloc.c: Catch some string size overflows that we were missing.
18181 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18182 for convenience in STRING_BYTES_MAX.
18183 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18184 The definition here is exact; the one in lisp.h was approximate.
18185 (allocate_string_data): Check for string overflow. This catches
18186 some instances we weren't catching before. Also, it catches
18187 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18188 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18189 and ptrdiff_t and EMACS_INT are both 64 bits.
18191 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18192 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18193 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18195 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18197 * alloc.c (Fmake_string): Check for out-of-range init.
18199 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18201 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18203 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18205 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18206 xg_get_default_scrollbar_width.
18208 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18209 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18210 (style_changed_cb): Call update_theme_scrollbar_width and call
18211 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18212 all frames (Bug#8505).
18213 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18214 Call gtk_window_set_resizable if HAVE_GTK3.
18215 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18216 and height if HAVE_GTK3 (Bug#8505).
18217 (scroll_bar_width_for_theme): New variable.
18218 (update_theme_scrollbar_width): New function.
18219 (xg_get_default_scrollbar_width): Move code to
18220 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18221 (xg_initialize): Call update_theme_scrollbar_width.
18223 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18225 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18227 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18229 * frame.c (make_frame): Call other_buffer_safely instead of
18232 * window.c (temp_output_buffer_show): Call display_buffer with
18233 second argument Vtemp_buffer_show_specifiers and reset latter
18234 immediately after the call.

18687 or arbitrary window as argument. Update doc-strings.
18688 (Fminibuffer_window): Move up in code.
18689 (Fwindow_minibuffer_p): Move up in code and simplify.
18690 (Fset_frame_selected_window): Move here from frame.c.
18692 (Fselected_window, select_window, Fselect_window): Move up in
18693 code. Minor doc-string fixes.
18695 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18697 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18698 Do not assume that spare memory exists; that assumption is valid
18699 only if SYSTEM_MALLOC.
18700 (LARGE_REQUEST): New macro, so that the issue of large requests
18701 is separated from the issue of spare memory.
18703 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18705 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18729 (x_clipboard_manager_save): Add return value.
18730 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
18731 New error handlers.
18732 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18733 Obey Vx_select_enable_clipboard_manager. Catch errors in
18734 x_clipboard_manager_save (Bug#8779).
18735 (Vx_select_enable_clipboard_manager): New variable.
18736 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18738 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18740 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18742 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18744 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18745 in the current matrix if keep_current_p is non-zero.

18749 * bidi.c (bidi_level_of_next_char): Fix last change.
18751 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18753 Support bidi reordering of text covered by display properties.
18755 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18756 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18757 (bidi_cache_search, bidi_cache_iterator_state)
18758 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18759 (bidi_level_of_next_char, bidi_move_to_visually_next):
18760 Support character positions inside a run of characters covered by a
18762 (bidi_paragraph_init, bidi_resolve_explicit_1)
18763 (bidi_level_of_next_char): Call bidi_fetch_char and
18764 bidi_fetch_char_advance instead of FETCH_CHAR and
18765 FETCH_CHAR_ADVANCE.
18766 (bidi_init_it): Initialize new members.
18767 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18769 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18770 instead of using explicit *_CHAR codes.
18771 (bidi_resolve_explicit, bidi_resolve_weak):
18772 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18773 bidirectional text is supported only in multibyte buffers.
18774 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18775 it to initialize the frame_window_p member of struct bidi_it.
18776 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18777 (bidi_resolve_explicit, bidi_resolve_weak)

18779 bidi_it->nchars is non-positive.
18780 (bidi_level_of_next_char): Don't try to lookup the cache for the
18781 next/previous character if nothing is cached there yet, or if we
18782 were just reseat()'ed to a new position.
18784 * xdisp.c (set_cursor_from_row): Set start and stop points
18785 according to the row's direction when priming the loop that looks
18786 for the glyph on which to display cursor.
18787 (single_display_spec_intangible_p): Function deleted.
18788 (display_prop_intangible_p): Reimplement to call
18789 handle_display_spec instead of single_display_spec_intangible_p.
18790 Accept 3 additional arguments needed by handle_display_spec.
18791 This fixes incorrect cursor motion across display property with complex
18792 values: lists, `(when COND...)' forms, etc.
18793 (single_display_spec_string_p): Support property values that are
18794 lists with the argument STRING its top-level element.
18795 (display_prop_string_p): Fix the condition for processing a
18796 property that is a list to be consistent with handle_display_spec.
18797 (handle_display_spec): New function, refactored from the
18798 last portion of handle_display_prop.
18799 (compute_display_string_pos): Accept additional argument
18800 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18801 value of a `display' property is a "replacing spec".
18802 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18803 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18804 the display property, but just return a value indicating whether
18805 the display property will replace the characters it covers.
18806 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18807 frame_window_p members of struct bidi_it.
18808 (compute_display_string_pos, compute_display_string_end):
18810 (push_it): Accept second argument POSITION, where pop_it should
18811 jump to continue iteration.
18812 (reseat_1): Initialize bidi_it.disp_pos.
18814 * keyboard.c (adjust_point_for_property): Adjust the call to
18815 display_prop_intangible_p to its new signature.
18817 * dispextern.h (struct bidi_it): New member frame_window_p.
18818 (bidi_init_it): Update prototypes.
18819 (display_prop_intangible_p): Update prototype.
18820 (compute_display_string_pos, compute_display_string_end):
18821 Declare prototypes.
18822 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18825 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18827 Malloc failure behavior now depends on size of allocation.
18828 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18829 * lisp.h: Change signatures accordingly.
18830 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18831 All callers changed. (Bug#8762)
18833 * gnutls.c: Use Emacs's memory allocators.
18834 Without this change, the gnutls library would invoke malloc etc.
18835 directly, which causes problems on non-SYNC_INPUT hosts, and which
18836 runs afoul of improving memory_full behavior. (Bug#8761)
18837 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18838 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18839 xfree instead of the default malloc, realloc, free.
18840 (Fgnutls_boot): No need to check for memory allocation failure,
18841 since xmalloc does that for us.
18843 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18844 * category.c (hash_get_category_set):
18845 * ccl.c (ccl_driver):
18846 * charset.c (Fdefine_charset_internal):
18847 * charset.h (struct charset.hash_index):

18849 (composition_gstring_put_cache):
18850 * composite.h (struct composition.hash_index):
18851 * dispextern.h (struct image.hash):
18852 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18853 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18854 (hashfn_equal, hashfn_user_defined, make_hash_table)
18855 (maybe_resize_hash_table, hash_lookup, hash_put)
18856 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18857 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18858 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18859 * image.c (make_image, search_image_cache, lookup_image)
18860 (xpm_put_color_table_h):
18861 * lisp.h (struct Lisp_Hash_Table):
18862 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18863 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18864 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18865 * alloc.c (allocate_vectorlike):
18866 Check for overflow in vector size calculations.
18867 * ccl.c (ccl_driver):
18868 Check for overflow when converting EMACS_INT to int.
18869 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18870 need to be updated by these changes.
18871 * fns.c (make_hash_table, maybe_resize_hash_table):
18872 Check for integer overflow with large hash tables.
18873 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18874 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18875 (SXHASH_REDUCE): New macro.
18876 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18877 Use it instead of discarding useful hash info with large hash values.
18878 (sxhash_float): New function.
18879 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18880 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18881 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18882 Rewrite to use FIXNUM_BITS, as this simplifies things.
18883 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18884 Adjust signatures to match updated version of code.
18885 (consing_since_gc): Now EMACS_INT, since a single hash table can
18886 use more than INT_MAX bytes.
18888 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18890 Make it possible to build with GCC-4.6+ -O2 -flto.
18892 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18894 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18896 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18897 Call minibuffer-inactive-mode.
18899 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18901 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18902 Update dependencies.
18904 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18906 * data.c (init_data): Remove code for UTS, this system is not
18909 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18911 Don't force ./temacs to start in terminal mode.
18913 * frame.c (make_initial_frame): Initialize faces in all cases, not
18914 only when CANNOT_DUMP is defined.
18915 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18917 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18919 * dispnew.c (add_window_display_history): Use const for the string
18920 pointer. Remove declaration, not needed.
18922 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18924 Use 'inline', not 'INLINE'.
18925 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18926 * alloc.c, fontset.c (INLINE): Remove.
18927 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18928 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18929 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18930 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18931 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18933 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18935 Make it possible to run ./temacs.
18937 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18938 syms_of_callproc does the same thing. Remove test for
18939 "initialized", do it in the caller.
18940 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18942 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18944 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18945 (read_minibuf): Use get_minibuffer.
18946 (syms_of_minibuf): Use DEFSYM.
18947 (Qmetadata): New var.
18948 * data.c (Qbuffer): Don't make it static.
18949 (syms_of_data): Use DEFSYM.
18951 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18953 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18954 (CCL_CODE_MIN): New macro.
18956 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18958 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18960 * eval.c (Qdebug): Now static.
18961 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18962 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18963 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18965 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18967 * image.c: Various fixes to ImageMagick code comments.
18968 (Fimagemagick_types): Doc fix.
18970 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18972 Minor fixes prompted by GCC 4.6.0 warnings.
18974 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18976 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18977 (x_clipboard_manager_save_all): Move extern decl to ...
18978 * xterm.h: ... here, so that it can be checked for consistency.
18980 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18982 * xselect.c (x_clipboard_manager_save_frame)
18983 (x_clipboard_manager_save_all): New functions.
18984 (Fx_clipboard_manager_save): Lisp function deleted.
18986 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18987 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18989 * xterm.h: Update prototype.
18991 2011-05-28 William Xu <william.xwl@gmail.com>
18993 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18994 exiting (Bug#8239).
18996 2011-05-28 Jim Meyering <meyering@redhat.com>
18998 Avoid a sign-extension bug in crypto_hash_function.
18999 * fns.c (to_uchar): Define.
19000 (crypto_hash_function): Use it to convert some newly-signed
19001 variables to unsigned, to avoid sign-extension bugs. For example,
19002 without this change, (md5 "truc") would evaluate to
19003 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19004 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19005 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19007 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19009 Integer overflow fixes.
19011 * dbusbind.c: Serial number integer overflow fixes.
19012 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19013 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19014 to hold a serial number that is too large for a fixnum.
19015 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19016 Check for serial numbers out of range. Decode any serial number
19017 that was so large that it became a float. (Bug#8722)
19019 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19020 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19021 Use XFASTINT rather than XUINT when numbers are nonnegative.
19022 (xd_append_arg, Fdbus_method_return_internal):
19023 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19024 arguments, check that Lisp number is nonnegative, rather than
19025 silently wrapping negative numbers around. (Bug#8722)
19026 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19029 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19031 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19033 ccl: Add integer overflow checks.
19034 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19035 (IN_INT_RANGE): New macros.
19036 (ccl_driver): Use them to check for integer overflow when
19037 decoding a CCL program. Many of the new checks are whether XINT (x)
19038 fits in int; it doesn't always, on 64-bit hosts. The new version
19039 doesn't catch all possible integer overflows, but it's an
19040 improvement. (Bug#8719)
19042 * alloc.c (make_event_array): Use XINT, not XUINT.
19043 There's no need for unsigned here.
19045 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19046 This follows up to the 2011-05-06 change that substituted uintptr_t
19047 for EMACS_INT. This case wasn't caught back then.
19049 Rework Fformat to avoid integer overflow issues.
19050 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19051 now (part of C89). Include <verify.h>.
19052 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19053 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19054 (Fformat): Avoid the prepass trying to compute sizes; it was only
19055 approximate and thus did not catch overflow reliably. Instead, walk
19056 through the format just once, formatting and computing sizes as we go,
19057 checking for integer overflow at every step, and allocating a larger
19058 buffer as needed. Keep track separately whether the format is
19059 multibyte. Keep only the most-recently calculated precision, rather
19060 than them all. Record whether each argument has been converted to
19061 string. Use EMACS_INT, not int, for byte and char and arg counts.
19062 Support field widths and precisions larger than INT_MAX. Avoid
19063 sprintf's undefined behavior with conversion specifications such as %#d
19064 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19065 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19066 formatting out-of-range floating point numbers with int
19067 formats. (Bug#8668)
19069 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19071 * data.c: Avoid integer truncation in expressions involving floats.
19072 * data.c: Include <intprops.h>.
19073 (arith_driver): When there's an integer overflow in an expression
19074 involving floating point, convert the integers to floating point
19075 so that the resulting value does not suffer from catastrophic
19076 integer truncation. For example, on a 64-bit host (* 4
19077 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19078 Do not rely on undefined behavior after integer overflow.
19080 merge count_size_as_multibyte, parse_str_to_multibyte
19081 * character.c, character.h (count_size_as_multibyte):
19082 Rename from parse_str_to_multibyte; all uses changed.
19083 Check for integer overflow.
19084 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19085 since it's now a duplicate of the other. This is more of
19086 a character than a buffer op, so better that it's in character.c.
19087 * fns.c, print.c: Adjust to above changes.
19089 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19091 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19093 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19095 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19096 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19097 (x_clipboard_manager_save): Now static.
19098 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19100 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19101 (crypto_hash_function): Now static.
19102 Fix pointer signedness problems. Avoid unnecessary initializations.
19104 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19106 * termhooks.h (Vselection_alist): Make it terminal-local.
19108 * terminal.c (create_terminal): Initialize it.
19110 * xselect.c: Support for clipboard managers.
19111 (Vselection_alist): Move to termhooks.h as terminal-local var.
19112 (LOCAL_SELECTION): New macro.
19113 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19114 (symbol_to_x_atom): Remove gratuitous arg.
19115 (x_handle_selection_request, lisp_data_to_selection_data)
19116 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19117 (x_own_selection, x_get_local_selection, x_convert_selection):
19118 New arg, specifying work frame. Use terminal-local Vselection_alist.
19119 (some_frame_on_display): Delete unused function.
19120 (Fx_own_selection_internal, Fx_get_selection_internal)
19121 (Fx_disown_selection_internal, Fx_selection_owner_p)
19122 (Fx_selection_exists_p): New optional frame arg.
19123 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19124 (x_handle_selection_clear): Don't treat other terminals with the
19125 same keyboard specially. Use the terminal-local Vselection_alist.
19126 (x_clear_frame_selections): Use Frun_hook_with_args.
19128 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19130 * xterm.h: Add support for those atoms.
19132 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19134 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19135 (converted_selections, conversion_fail_tag): New global variables.
19136 (x_selection_request_lisp_error): Free the above.
19137 (x_get_local_selection): Remove unnecessary code.
19138 (x_reply_selection_request): Args changed; handle arbitrary array
19139 of converted selections stored in converted_selections.
19140 Separate the XChangeProperty and SelectionNotify steps.
19141 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19142 (x_convert_selection): New function.
19143 (x_handle_selection_event): Simplify.
19144 (x_get_foreign_selection): Don't ignore incoming requests while
19145 waiting for an answer; this will fail when we implement
19146 SAVE_TARGETS, and seems unnecessary anyway.
19147 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19148 (Vx_sent_selection_functions): Doc fix.
19150 2011-05-26 Leo Liu <sdl.web@gmail.com>
19152 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19154 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19156 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19158 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19159 for fringe update if it has periodic bitmap.
19160 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19161 and fringe_bitmap_periodic_p.
19163 * fringe.c (get_fringe_bitmap_data): New function.
19164 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19165 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19166 row. Mark glyph row for fringe update if periodicity changed.
19168 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19169 for fringe update unless it has periodic bitmap.
19171 2011-05-25 Kenichi Handa <handa@m17n.org>
19173 * xdisp.c (get_next_display_element): Set correct it->face_id for
19174 a static composition.
19176 2011-05-24 Leo Liu <sdl.web@gmail.com>
19179 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19181 * fns.c (crypto_hash_function, Fsha1): New function.
19182 (Fmd5): Use crypto_hash_function.
19183 (syms_of_fns): Add Ssha1.
19185 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19187 * gnutls.c: Remove unused macros.
19188 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19189 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19190 Remove macros that are defined and never used.
19191 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19193 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19195 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19196 (Fx_get_selection_internal): Minor cleanup.
19197 (Fx_own_selection_internal): Rename arguments for consistency with
19200 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19202 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19204 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19206 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19208 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19210 * dispnew.c (scrolling_window): Don't exclude the case that the
19211 last enabled row in the desired matrix touches the bottom boundary.
19213 2011-05-21 Glenn Morris <rgm@gnu.org>
19215 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19216 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19217 and add some more files.
19219 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19221 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19222 report_file_error introduced by the change from 2011-05-07.
19224 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19226 * systime.h (Time): Define only if emacs is defined.
19227 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19228 where the include path doesn't have X11/X.h by default. See
19229 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19231 2011-05-20 Kenichi Handa <handa@m17n.org>
19233 * composite.c (find_automatic_composition): Fix previous change.
19235 2011-05-20 Glenn Morris <rgm@gnu.org>
19237 * lisp.mk: New file, split from Makefile.in.
19238 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19239 (shortlisp): Remove.
19240 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19242 2011-05-19 Glenn Morris <rgm@gnu.org>
19244 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19245 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19246 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19247 (lisp): Set the order to that of loadup.el.
19248 (shortlisp): Make it a copy of $lisp.
19249 (SOME_MACHINE_LISP): Remove.
19250 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19251 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19253 2011-05-18 Kenichi Handa <handa@m17n.org>
19255 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19256 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19257 (find_automatic_composition): Mostly rewrite for efficiency.
19259 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19261 * makefile.w32-in: Update dependencies.
19263 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19265 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19266 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19268 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19270 Fix some integer overflow issues, such as string length overflow.
19272 * insdel.c (count_size_as_multibyte): Check for string overflow.
19274 * character.c (lisp_string_width): Check for string overflow.
19275 Use EMACS_INT, not int, for string indexes and lengths; in
19276 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19277 the resulting string length overflows an EMACS_INT; instead,
19278 report a string overflow if no precision given. When checking for
19279 precision exhaustion, use a check that cannot possibly have
19280 integer overflow. (Bug#8675)
19281 * character.h (lisp_string_width): Adjust to new signature.
19283 * alloc.c (string_overflow): New function.
19284 (Fmake_string): Use it. This doesn't change behavior, but saves
19285 a few bytes and will simplify future changes.
19286 * character.c (string_escape_byte8): Likewise.
19287 * lisp.h (string_overflow): New decl.
19289 Fixups, following up to the user-interface timestamp change.
19290 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19291 for UI timestamps, instead of unsigned long.
19292 * msdos.c (mouse_get_pos): Likewise.
19293 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19294 * w32gui.h (Time): Define by including "systime.h" rather than by
19295 declaring it ourselves. (Bug#8664)
19297 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19298 * image.c (clear_image_cache): Likewise.
19300 * term.c (term_mouse_position): Don't assume time_t wraparound.
19302 Be more systematic about user-interface timestamps.
19303 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19304 and sometimes 'EMACS_UINT', to represent these timestamps.
19305 This change causes it to use 'Time' uniformly, as that's what X uses.
19306 This makes the code easier to follow, and makes it easier to catch
19307 integer overflow bugs such as Bug#8664.
19308 * frame.c (Fmouse_position, Fmouse_pixel_position):
19309 Use Time, not unsigned long, for user-interface timestamps.
19310 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19311 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19312 * keyboard.h (last_event_timestamp): Likewise.
19313 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19314 * menu.h (xmenu_show): Likewise.
19315 * term.c (term_mouse_position): Likewise.
19316 * termhooks.h (struct input_event.timestamp): Likewise.
19317 (struct terminal.mouse_position_hook): Likewise.
19318 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19319 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19320 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19321 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19322 what it was before.
19323 * menu.h, termhooks.h: Include "systime.h", for Time.
19325 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19326 Don't assume that the difference between two unsigned long values
19327 can fit into an integer. At this point, we know button_down_time
19328 <= event->timestamp, so the difference must be nonnegative, so
19329 there's no need to cast the result if double-click-time is
19330 nonnegative, as it should be; check that it's nonnegative, just in
19331 case. This bug is triggered when events are more than 2**31 ms
19332 apart (about 25 days). (Bug#8664)
19334 * xselect.c (last_event_timestamp): Remove duplicate decl.
19335 (x_own_selection): Remove needless cast to unsigned long.
19337 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19338 that always fit in int. Use a sentinel instead of a counter, to
19339 avoid a temp and to allay GCC's concerns about possible int overflow.
19340 * frame.h (struct frame): Use int for menu_bar_items_used
19341 instead of EMACS_INT, since it always fits in int.
19343 * menu.c (grow_menu_items): Check for int overflow.
19345 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19347 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19348 Before, the code was not consistent. These values cannot exceed
19349 2**31 - 1 so there's no need to make them unsigned.
19350 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19351 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19352 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19354 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19356 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19357 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19358 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19359 presumably because the widths might not match.
19361 * window.c (size_window): Avoid needless test at loop start.
19363 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19365 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19367 2011-05-12 Drew Adams <drew.adams@oracle.com>
19369 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19371 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19373 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19374 `width' to `bar_area_x' and `bar_area_width', respectively.
19375 (x_scroll_run): Take account of fringe background extension.
19377 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19378 Rename local vars `left' and `width' to `bar_area_x' and
19379 `bar_area_width', respectively.
19380 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19381 background extension.
19383 2011-05-10 Jim Meyering <meyering@redhat.com>
19385 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19387 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19389 * image.c (Finit_image_library): Return t for built-in image types,
19390 like pbm and xbm. (Bug#8640)
19392 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19394 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19396 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19398 * w32console.c (Fset_screen_color): Doc fix.
19399 (Fget_screen_color): New function.
19400 (syms_of_ntterm): Defsubr it.
19402 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19403 unlink the temporary file if Fcall_process didn't create it in the
19405 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19406 child process will be redirected to a file specified with `:file'.
19407 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19408 cue to call_process_cleanup not to close that handle.
19410 2011-05-07 Ben Key <bkey76@gmail.com>
19412 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19413 one of two shell specific rules, either bootstrap-temacs-CMD or
19414 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19415 to the previous implementation of the bootstrap-temacs rule.
19416 The bootstrap-temacs-CMD rule is similar to the previous
19417 implementation of the bootstrap-temacs rule except that it
19418 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19421 These changes, along with some changes to nt/configure.bat,
19422 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19423 earlier fix to add support for --cflags and --ldflags options
19424 that include quotes so that it works whether make uses cmd or
19427 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19429 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19430 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19432 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19433 a string. Handle both cases.
19434 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19435 (Fdbus_register_method): Use Qinvalid_function.
19437 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19439 * makefile.w32-in: Update dependencies.
19440 (LISP_H): Add inttypes.h and stdin.h.
19441 (PROCESS_H): Add unistd.h.
19443 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19445 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19446 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19448 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19450 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19452 * term.c (vfatal): Remove stray call to va_end.
19453 It's not needed and the C Standard doesn't allow it here anyway.
19455 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19456 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19458 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19461 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19463 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19465 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19467 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19469 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19471 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19472 * charset.c (Fdefine_charset_internal): Don't initialize
19473 charset.code_space[15]. The value was garbage, on hosts with
19474 32-bit int (Bug#8600).
19476 * lread.c (read_integer): Be more consistent with string-to-number.
19477 Use string_to_number to do the actual conversion; this avoids
19478 rounding errors and fixes some other screwups. Without this fix,
19479 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19480 (digit_to_number): Move earlier, for benefit of read_integer.
19481 Return -1 if the digit is out of range for the base, -2 if it is
19482 not a digit in any supported base. (Bug#8602)
19484 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19486 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19487 to match comment at start of function. This also removes a
19488 GCC warning about overflow in a 32+64-bit port.
19490 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19492 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19493 Reported by Stefan Monnier in
19494 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19495 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19496 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19498 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19499 (EMACS_UINTPTR): Likewise, with uintptr_t.
19501 * lisp.h: Prefer 64-bit EMACS_INT if available.
19502 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19503 on 32-bit hosts that have 64-bit int, so that they can access
19505 However, temporarily disable this change unless the temporary
19506 symbol WIDE_EMACS_INT is defined.
19508 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19510 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19511 This removes an assumption that EMACS_INT and long are the same
19512 width as pointers. The assumption is true for Emacs porting targets
19513 now, but we want to make other targets possible.
19514 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19515 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19516 In the rest of the code, change types of integers that hold casted
19517 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19518 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19519 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19520 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19521 No need to cast type when ORing.
19522 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19523 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19524 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19525 assume EMACS_INT is the same width as char *.
19526 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19527 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19528 Remove no-longer-needed casts.
19529 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19530 (xg_tool_bar_help_callback, xg_make_tool_item):
19531 Use EMACS_INTPTR to hold an integer
19532 that will be cast to void *; this can avoid a GCC warning
19533 if EMACS_INT is not the same width as void *.
19534 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19535 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19536 (current_message_1, set_message_1):
19537 Use a local to convert to proper width without a cast.
19538 * xmenu.c (dialog_selection_callback): Likewise.
19540 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19541 Also, don't assume VALBITS / RAND_BITS is less than 5,
19542 and don't rely on undefined behavior when shifting a 1 left into
19544 * lisp.h (get_random): Change signature to match.
19546 * lread.c (hash_string): Use size_t, not int, for hash computation.
19547 Normally we prefer signed values; but hashing is special, because
19548 it's better to use unsigned division on hash table sizes so that
19549 the remainder is nonnegative. Also, size_t is the natural width
19550 for hashing into memory. The previous code used 'int', which doesn't
19551 retain enough info to hash well into very large tables.
19552 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19554 * dbusbind.c: Don't possibly lose pointer info when converting.
19555 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19556 Use XPNTR rather than XHASH, so that the high-order bits of
19557 the pointer aren't lost when converting through void *.
19559 * eval.c (Fautoload): Don't double-shift a pointer.
19561 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19595 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19596 Remove unused parameter `fildes'.
19597 * process.c (read_process_output, send_process): Don't pass it.
19599 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19601 Fix previous change: the library cache is defined in w32.c.
19602 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19603 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

19646 instead of gnutls_record_check_pending.
19648 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19650 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19652 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19653 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19656 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19658 * xterm.c (x_set_frame_alpha): Do not set property on anything

19695 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19697 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19698 rather than `XVECTOR (FOO)->size'.
19700 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19701 inttypes.h, as a gnulib replacement is used if it not available in
19704 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19706 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19707 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19708 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19710 * coding.c (coding_alloc_by_realloc): Error out if destination
19711 will grow beyond MOST_POSITIVE_FIXNUM.
19712 (decode_coding_emacs_mule): Abort if there isn't enough place in
19713 charbuf for the composition carryover bytes. Reserve an extra
19714 space for up to 2 characters produced in a loop.

19750 * doprnt.c (doprnt): Don't return value smaller than the buffer
19751 size if the message was truncated. (Bug#8545).
19753 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19755 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

19762 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19764 * makefile.w32-in: Update dependencies.
19766 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19768 Improve `doprnt' and its usage. (Bug#8545)
19769 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19770 `format_end'. Remove support for %l as a conversion specifier.
19771 Don't use xrealloc. Improve diagnostics when the %l size modifier
19772 is used. Update the commentary.
19774 * eval.c (verror): Simplify calculation of size_t.
19776 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19779 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19781 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19784 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19786 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19787 This makes this file independent of the recent pseudovector change.
19789 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19791 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19793 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19794 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19795 Remove unused local.
19796 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19798 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19799 GCC 4.6.0 optimizes based on type-based alias analysis.
19800 For example, if b is of type struct buffer * and v of type struct
19801 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19802 != &v->size, and therefore "v->size = 1; b->size = 2; return
19803 v->size;" must therefore return 1. This assumption is incorrect
19804 for Emacs, since it type-puns struct Lisp_Vector * with many other
19805 types. To fix this problem, this patch adds a new type struct
19806 vectorlike_header that documents the constraints on layout of vectors
19807 and pseudovectors, and helps optimizing compilers not get fooled
19808 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19809 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19810 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19812 (XSETPVECTYPE): Rewrite in terms of new macro.
19813 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19814 This is a bit clearer, and further avoids the possibility of
19815 undesirable aliasing.
19816 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19817 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19818 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19819 since Lisp_Subr is a special case (no "next" field).
19820 (ASIZE): Now uses header.size rather than size.
19821 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19822 to avoid the hassle of writing XVECTOR (foo)->header.size.
19823 (struct vectorlike_header): New type.
19824 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19825 object, to help avoid aliasing.
19826 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19827 (SUBRP): Likewise, since Lisp_Subr is a special case.
19828 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19829 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19830 (struct Lisp_Hash_Table): Combine first two members into a single
19831 struct vectorlike_header member. All uses of "size" and "next" members
19832 changed to be "header.size" and "header.next".
19833 * buffer.h (struct buffer): Likewise.
19834 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19835 * frame.h (struct frame): Likewise.
19836 * process.h (struct Lisp_Process): Likewise.
19837 * termhooks.h (struct terminal): Likewise.
19838 * window.c (struct save_window_data, struct saved_window): Likewise.
19839 * window.h (struct window): Likewise.
19840 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19841 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19842 * buffer.c (init_buffer_once): Likewise.
19843 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19845 * process.c (Fformat_network_address): Use local var for size,
19848 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19850 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19851 * data.c (atof): Remove decl; no longer used or needed.
19852 (digit_to_number): Move to lread.c.
19853 (Fstring_to_number): Use new string_to_number function, to be
19854 consistent with how the Lisp reader treats infinities and NaNs.
19855 Do not assume that floating-point numbers represent EMACS_INT
19856 without losing information; this is not true on most 64-bit hosts.
19857 Avoid double-rounding errors, by insisting on integers when
19858 parsing non-base-10 numbers, as the documentation specifies.
19859 * lisp.h (string_to_number): New decl, replacing ...
19860 (isfloat_string): Remove.
19861 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19862 (read1): Do not accept +. and -. as integers; this
19863 appears to have been a coding error. Similarly, do not accept
19864 strings like +-1e0 as floating point numbers. Do not report
19865 overflow for integer overflows unless the base is not 10 which
19866 means we have no simple and reliable way to continue.
19867 Break out the floating-point parsing into a new
19868 function string_to_number, so that Fstring_to_number parses
19869 floating point numbers consistently with the Lisp reader.
19870 (digit_to_number): Move here from data.c. Make it static inline.
19871 (E_CHAR, EXP_INT): Remove, replacing with ...
19872 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19873 (string_to_number): New function, replacing isfloat_string.
19874 This function checks for valid syntax and produces the resulting
19875 Lisp float number too. Rework it so that string-to-number
19876 no longer mishandles examples like "1.0e+". Use strtoumax,
19877 so that overflow for non-base-10 numbers is reported only when
19878 there's no portable and simple way to convert to floating point.
19880 * textprop.c (set_text_properties_1): Rewrite for clarity,
19881 and to avoid GCC warning about integer overflow.
19883 * intervals.h (struct interval): Use EMACS_INT for members
19884 where EMACS_UINT might cause problems. See
19885 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19886 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19887 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19889 (offset_intervals): Tell GCC not to worry about length overflow
19890 when negating a negative length.
19892 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19893 (overrun_check_free): Likewise.
19895 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19896 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19899 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19900 (gnutls_make_error): Rename local to avoid shadowing.
19901 (gnutls_emacs_global_deinit): ifdef out; not used.
19902 (Fgnutls_boot): Use const for pointer to readonly storage.
19903 Comment out unused local. Fix pointer signedness problems.
19905 * lread.c (openp): Don't stuff size_t into an 'int'.
19906 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19907 about possible signed overflow.
19909 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19910 (GDK_KEY_g): Don't define if already defined.
19911 (xg_prepare_tooltip): Avoid pointer signedness problem.
19912 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19914 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19915 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19917 * xfns.c (Fx_window_property): Simplify a bit,
19918 to make a bit faster and to avoid GCC 4.6.0 warning.
19919 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19921 * fns.c (internal_equal): Don't assume size_t fits in int.
19923 * alloc.c (compact_small_strings): Tighten assertion a little.
19925 Replace pEd with more-general pI, and fix some printf arg casts.
19926 * lisp.h (pI): New macro, generalizing old pEd macro to other
19927 conversion specifiers. For example, use "...%"pI"d..." rather
19928 than "...%"pEd"...".
19929 (pEd): Remove. All uses replaced with similar uses of pI.
19930 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19931 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19932 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19933 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19934 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19935 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19936 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19938 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19939 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19940 * print.c (safe_debug_print, print_object): Likewise.
19941 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19943 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19944 avoiding the 0 flag, which is not portable.
19945 * process.c (Fmake_network_process): Use pI to avoid cast.
19946 * region-cache.c (pp_cache): Likewise.
19947 * xdisp.c (decode_mode_spec): Likewise.
19948 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19949 behavior on 64-bit hosts with printf arg.
19950 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.

19952 (x_get_window_property): Don't truncate byte count to an 'int'
19955 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19956 here, since it parses constructs like leading '-' and spaces,
19957 which are not wanted; and it overflows with large numbers.
19958 Instead, simply match F[0-9]+, which is what is wanted anyway.
19960 * alloc.c: Remove unportable assumptions about struct layout.
19961 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19962 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):

19964 plus offsetof, to remove unportable assumptions about struct layout.
19965 These assumptions hold on all porting targets that I know of, but
19966 they are not guaranteed, they're easy to remove, and removing them
19967 makes further changes easier.
19969 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19970 This doesn't fix a bug but makes the code clearer.
19971 (string_overrun_cookie): Now const. Use initializers that
19972 don't formally overflow signed char, to avoid warnings.
19973 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19974 can cause Emacs to crash when string overrun checking is enabled.
19975 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19976 multiple of sizeof (EMACS_INT); it need not be, if
19977 alignof(EMACS_INT) < sizeof (EMACS_INT).

20013 * doprnt.c (doprnt): Document the set of format control sequences
20014 supported by the function. Use SAFE_ALLOCA instead of always
20017 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20018 is one byte too soon. Don't use xrealloc; instead xfree and

20030 docstring. Start callback support.
20031 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20032 unless a fatal error occurred. Call gnutls_alert_send_appropriate

20145 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20146 to `error' in error message about FINAL_CHAR argument. Make sure
20147 FINAL_CHAR is a character, and use %c when it is passed as
20148 argument to `error'.
20150 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20152 * s/ms-w32.h (localtime): Redirect to sys_localtime.
20154 * w32.c: Include <time.h>.

20218 * dispextern.h (struct redisplay_interface): Rename param
20219 to avoid shadowing.
20220 * termhooks.h (struct terminal): Likewise.

20337 * nsfont.m: Fixed bugs in ns_get_family and
20338 ns_descriptor_to_entity that were caused by using free to
20339 deallocate memory blocks that were allocated by xmalloc (via
20340 xstrdup). This caused Emacs to crash when compiled with
20341 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20342 --enable-checking=xmallocoverrun). xfree is now used to
20343 deallocate these memory blocks.

20360 (emacs_read, emacs_write): Use it.
20361 * process.c (send_process): Adjust to the new signatures of
20362 emacs_write and emacs_gnutls_write. Do not attempt to store

20841 is outside the buffer's accessible region. (Bug#8468)
20843 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20845 Fix write-region and its subroutines for buffers > 2GB.
20846 * fileio.c (a_write, e_write): Modify declaration of arguments and
20847 local variables to support buffers larger than 2GB.
20848 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20850 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20851 argument, local variables, and return value.
20853 * lisp.h: Update prototypes of emacs_write and emacs_read.
20855 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20857 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20859 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20861 Fix more problems found by GCC 4.6.0's static checks.
20863 * xdisp.c (vmessage): Use a better test for character truncation.
20865 * charset.c (load_charset_map): <, not <=, for optimization,
20866 and to avoid potential problems with integer overflow.
20867 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20868 * casetab.c (set_identity, shuffle): Likewise.
20869 * editfns.c (Fformat): Likewise.
20870 * syntax.c (skip_chars): Likewise.
20872 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20873 This also lets GCC 4.6.0 generate slightly better loop code.
20875 * callint.c (Fcall_interactively): <, not <=, for optimization.
20876 (Fcall_interactively): Count the number of arguments produced,
20877 not the number of arguments given. This is simpler and lets GCC
20878 4.6.0 generate slightly better code.
20880 * ftfont.c: Distingish more carefully between FcChar8 and char.
20881 The previous code passed unsigned char * to a functions like
20882 strlen and xstrcasecmp that expect char *, which does not
20883 conform to the C standard.
20884 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20885 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20886 char * when the C standard requires it.
20888 * keyboard.c (read_char): Remove unused var.
20890 * eval.c: Port to Windows vsnprintf (Bug#8435).
20891 Include <limits.h>.
20892 (SIZE_MAX): Define if the headers do not.
20893 (verror): Do not give up if vsnprintf returns a negative count.
20894 Instead, grow the buffer. This ports to Windows vsnprintf, which
20895 does not conform to C99. Problem reported by Eli Zaretskii.
20896 Also, simplify the allocation scheme, by avoiding the need for
20897 calling realloc, and removing the ALLOCATED variable.
20899 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20901 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20902 But keep the doprint source code for now, as we might revamp it
20903 and use it again (Bug#8435).
20904 * lisp.h (doprnt): Remove.
20905 * Makefile.in (base_obj): Remove doprnt.o.
20906 * deps.mk (doprnt.o): Remove.
20908 error: Print 32- and 64-bit integers portably (Bug#8435).
20909 Without this change, on typical 64-bit hosts error ("...%d...", N)
20910 was used to print both 32- and 64-bit integers N, which relied on
20911 undefined behavior.
20912 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20913 * lisp.h (error, verror): Mark as printf-like functions.
20914 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20915 Report overflow in size calculations when allocating printf buffer.
20916 Do not truncate output string at its first null byte.
20917 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20918 Truncate the output at a character boundary, since vsnprintf does not
20920 * charset.c (check_iso_charset_parameter): Convert internal
20921 character to string before calling 'error', since %c now has the
20923 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20924 overflow when computing char to be passed to 'error'. Do not
20925 pass Lisp_Object to 'error'; pass the integer instead.
20926 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20927 formatted with plain %d.
20929 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20931 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20933 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20935 * xterm.c (x_catch_errors): Remove duplicate declaration.
20937 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20939 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20941 2011-04-10 Jim Meyering <meyering@redhat.com>
20943 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20944 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20945 return ssize_t not "int", and use size_t as the buffer length.
20946 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20947 * gnutls.h: Update declarations.
20948 * process.c (read_process_output): Use ssize_t, to match.
20949 (send_process): Likewise.
20951 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20953 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20955 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20957 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20958 Use unsigned char, to match FcChar8 type definition.
20960 * xterm.c (handle_one_xevent):
20961 * xmenu.c (create_and_show_popup_menu):
20962 * xselect.c (x_decline_selection_request)
20963 (x_reply_selection_request): Avoid type-punned deref of X events.
20965 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20967 Fix some uses of `int' instead of EMACS_INT.
20968 * search.c (string_match_1, fast_string_match)
20969 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20970 (scan_buffer, find_next_newline_no_quit)
20971 (find_before_next_newline, search_command, Freplace_match)
20972 (Fmatch_data): Make some `int' variables be EMACS_INT.
20974 * xdisp.c (display_count_lines): 3rd argument and return value now
20975 EMACS_INT. All callers changed.
20976 (pint2hrstr): Last argument is now EMACS_INT.
20978 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20979 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20980 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20981 (decode_coding_utf_16, decode_coding_emacs_mule)
20982 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20983 (decode_coding_ccl, decode_coding_charset)
20984 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20985 (decode_coding_iso_2022, decode_coding_emacs_mule)
20986 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20987 <char_offset, last_offset>: Declare EMACS_INT.
20988 (encode_coding_utf_8, encode_coding_utf_16)
20989 (encode_coding_emacs_mule, encode_invocation_designation)
20990 (encode_designation_at_bol, encode_coding_iso_2022)
20991 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20992 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20994 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20995 (encode_invocation_designation): Last argument P_NCHARS is now
20997 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20998 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21000 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21003 * ccl.c (Fccl_execute_on_string): Declare some variables
21006 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21008 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21010 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21012 * process.c (Fformat_network_address): Doc fix.
21014 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21016 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21018 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21020 * keyboard.c (read_char): Call Lisp function help-form-show,
21021 instead of using internal_with_output_to_temp_buffer.
21022 (Qhelp_form_show): New var.
21023 (syms_of_keyboard): Use DEFSYM macro.
21025 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21027 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21029 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21031 * process.c (Flist_processes): Remove to Lisp.
21032 (list_processes_1): Delete.

21036 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21038 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21040 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21042 Fix more problems found by GCC 4.6.0's static checks.
21044 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21046 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21048 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21050 * xdisp.c (vmessage): Mark as a printf-like function.
21052 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21054 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21056 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21057 printf-like functions.
21058 (tiff_load): Add casts to remove these marks before passing them
21059 to system-supplied API.
21061 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21063 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21064 This avoids several warnings with gcc -Wstrict-overflow.
21065 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21066 directly, rather than having caller test rule sign. This avoids
21067 some unnecessary tests.
21068 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21069 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21070 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21072 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21073 (xfont_open): Avoid unnecessary tests.
21075 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21077 * composite.h, composite.c (composition_gstring_put_cache):
21078 Use EMACS_INT, not int, for length.

21081 breaking out part of COMPOSITION_DECODE_RULE.
21082 (COMPOSITION_DECODE_RULE): Use it.
21083 * composite.c (get_composition_id): Remove unused local vars,
21084 by using the new macro.
21086 * textprop.c (set_text_properties_1): Change while to do-while,
21087 since the condition is always true at first.
21089 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21090 (interval_deletion_adjustment): Return unsigned value.
21093 * process.c (list_processes_1, create_pty, read_process_output):

21103 (update_syntax_table): Use unsigned instead of int.
21105 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21106 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21107 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21109 * print.c (print_error_message): Avoid int overflow.
21111 * font.c (font_list_entities): Redo for clarity,
21112 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21114 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21115 (font_score): Avoid potential overflow in diff calculation.
21117 * fns.c (substring_both): Remove var that is set but not used.
21118 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21120 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21122 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21123 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21124 can always succeed if overflow has undefined behavior.
21126 * search.c (boyer_moore, wordify): Remove vars set but not used.
21127 (wordify): Omit three unnecessary tests.
21129 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21130 All callers changed. This avoids the need for an unused var.
21132 * casefiddle.c (casify_region): Remove var that is set but not used.
21134 * dired.c (file_name_completion): Remove var that is set but not used.
21136 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21138 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21139 (Finsert_file_contents): Remove unnecessary code checking fd.
21141 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21142 Check for integer overflow on size calculations.
21144 * buffer.c (Fprevious_overlay_change): Remove var that is set
21147 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21148 Remove vars that are set but not used.
21149 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21150 (timer_check_2): Mark vars as initialized.
21152 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21154 * image.c (lookup_image): Remove var that is set but not used.
21155 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21157 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21158 that are set but not used.
21160 * xfns.c (make_invisible_cursor): Don't return garbage
21161 if XCreateBitmapFromData fails (Bug#8410).
21163 * xselect.c (x_get_local_selection, x_handle_property_notify):
21164 Remove vars that are set but not used.
21166 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

21176 (map_tty_color) [!defined MSDOS]: Likewise.
21178 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21180 * coding.c: Remove vars that are set but not used.
21181 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21182 All callers changed.

21184 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21185 (decode_coding_charset): Remove vars that are set but not used.
21187 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21188 that is set but not used.
21190 * print.c (print_object): Remove var that is set but not used.
21192 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21193 The gnulib version avoids calling malloc in the usual case,
21194 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21195 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21196 * filelock.c (current_lock_owner): Likewise.
21197 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

21200 (emacs_readlink): New function.
21201 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21202 ../lib/careadlinkat.h.
21204 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21206 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21207 first non-nil return value).

21221 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21222 and thereabouts. All callers changed.
21223 (get_per_char_metric): Remove parameter `f', unused since
21224 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21228 do not dereference NULL upon failed strdup
21229 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21230 (ns_get_family): Likewise.
21232 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

21306 (try_scrolling): Use it when setting scroll_limit.
21307 Limit scrolling to 100 screen lines.
21308 (redisplay_window): Even when falling back on "recentering",
21309 position point in the window according to scroll-conservatively,
21310 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21312 (try_scrolling): When point is above the window, allow searching
21313 as far as scroll_max, or one screenful, to compute vertical
21314 distance from PT to the scroll margin position. This prevents
21315 try_scrolling from unnecessarily failing when
21316 scroll-conservatively is set to a value slightly larger than the
21317 window height. Clean up the case of PT below the margin at bottom
21318 of window: scroll_max can no longer be INT_MAX. When aggressive
21319 scrolling is in use, don't let point enter the opposite scroll
21320 margin as result of the scroll.
21321 (syms_of_xdisp) <scroll-conservatively>: Document the
21322 threshold of 100 lines for never-recentering scrolling.
21324 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21326 * dispextern.h (move_it_by_lines):
21327 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21328 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21329 (message_log_check_duplicate): Remove parameters `prev_bol' and
21330 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21331 (redisplay_internal): Remove parameter `preserve_echo_area',
21332 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21334 * indent.c (Fvertical_motion):
21335 * window.c (window_scroll_pixel_based, Frecenter):
21336 Don't pass `need_y_p' to `move_it_by_lines'.
21338 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21340 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21341 steal a few bits to be more compact.
21342 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21343 Remove unneeded casts.
21345 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21347 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21349 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21350 binding" message (bug#7967).
21352 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21354 Fix more problems found by GCC 4.6.0's static checks.
21356 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21357 Remove unused local var.
21359 * editfns.c (Fmessage_box): Remove unused local var.
21361 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21362 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21363 Omit unused local vars.
21364 * window.c (shrink_windows): Omit unused local var.
21365 * menu.c (digest_single_submenu): Omit unused local var.
21366 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21367 Omit unused local var.
21369 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21370 Don't assume string length fits in int.
21371 (keyremap_step, read_key_sequence): Use size_t for sizes.
21372 (read_key_sequence): Don't check last_real_key_start redundantly.
21374 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21375 instead of alloca (Bug#8344).
21377 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21378 (Fbacktrace_frame): Don't assume nframes fits in int.
21380 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21382 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21385 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21387 * cm.c (calccost): Turn while-do into do-while, for clarity.
21389 * keyboard.c (syms_of_keyboard): Use the same style as later
21390 in this function when indexing through an array. This also
21391 works around GCC bug 48267.
21393 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21395 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21397 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21398 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21400 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21401 This avoids undefined behavior on integer overflow, and is a bit
21402 more convenient anyway since it is compared to a size_t variable.
21404 Variadic C functions now count arguments with size_t, not int.
21405 This avoids an unnecessary limitation on 64-bit machines, which
21406 caused (substring ...) to crash on large vectors (Bug#8344).
21407 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21408 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21412 * editfns.c (general_insert_function): Likewise.
21413 * eval.c (struct backtrace.nargs, interactive_p)
21414 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21415 (funcall_lambda, mark_backtrace): Likewise.
21416 * fns.c (concat): Likewise.
21417 * frame.c (x_set_frame_parameters): Likewise.
21418 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21419 0 if not found, not -1. All callers changed.
21421 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21422 (stack_copy_size): Now size_t, not int.
21423 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21425 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21427 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21428 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21429 All callers changed.
21431 * lisp.h (multibyte_char_to_unibyte):
21432 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21433 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21434 * character.h (CHAR_TO_BYTE8):
21435 * cmds.c (internal_self_insert):
21436 * editfns.c (general_insert_function):
21437 * keymap.c (push_key_description):
21438 * search.c (Freplace_match):
21439 * xdisp.c (message_dolog, set_message_1): All callers changed.
21441 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21443 * keyboard.c (safe_run_hook_funcall): New function.
21444 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21445 don't set the hook to nil, but remove the offending function instead.
21446 (Qcommand_hook_internal): Remove, unused.
21447 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21448 Vcommand_hook_internal.
21450 * eval.c (enum run_hooks_condition): Remove.
21451 (funcall_nil, funcall_not): New functions.
21452 (run_hook_with_args): Call each function through a `funcall' argument.
21453 Remove `cond' argument, now redundant.
21454 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21455 (Frun_hook_with_args_until_failure): Adjust accordingly.
21456 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21458 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21460 * dispextern.h (string_buffer_position): Remove declaration.
21462 * print.c (strout): Remove parameter `multibyte', unused since
21463 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21465 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21466 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21467 All callers changed.
21469 * w32.c (_wsa_errlist): Use braces for struct initializers.
21471 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21472 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21473 All callers changed.
21474 (string_buffer_position): Likewise. Also, make static (it's never
21475 used outside xdisp.c).
21476 (cursor_row_p): Remove parameter `w', unused since
21477 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21479 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21480 All callers changed.
21482 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21484 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21495 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21497 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21499 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21501 2011-03-27 Glenn Morris <rgm@gnu.org>

21504 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21505 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21506 Replace SIGTYPE with void everywhere.
21507 * s/usg5-4-common.h (SIGTYPE): Remove definition.

21510 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21512 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21513 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21515 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21517 * w32.c (read_unc_volume): Use parameter `henum', instead of
21518 global variable `wget_enum_handle'.
21520 * keymap.c (describe_vector): Remove parameters `indices' and
21521 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21524 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21526 * keyboard.c (timer_check): Remove parameter `do_it_now',
21527 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21528 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21529 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
21531 * keyboard.c (read_char):
21532 * w32menu.c (w32_menu_display_help):
21533 * xmenu.c (show_help_event, menu_help_callback):
21534 Adjust calls to `show_help_echo'.
21536 * gtkutil.c (xg_maybe_add_timer):
21537 * keyboard.c (readable_events):
21538 * process.c (wait_reading_process_output):
21539 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21541 * insdel.c (adjust_markers_gap_motion):
21542 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21616 2011-03-23 Julien Danjou <julien@danjou.info>
21618 * term.c (Fsuspend_tty, Fresume_tty):
21619 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21620 * window.c (temp_output_buffer_show):
21621 * insdel.c (signal_before_change):
21622 * frame.c (Fhandle_switch_frame):
21623 * fileio.c (Fdo_auto_save):
21624 * emacs.c (Fkill_emacs):
21625 * editfns.c (save_excursion_restore):
21626 * cmds.c (internal_self_insert):
21627 * callint.c (Fcall_interactively):
21628 * buffer.c (Fkill_all_local_variables):
21629 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21631 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21632 unconditionally since it does the check itself.
21634 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21636 Fix more problems found by GCC 4.5.2's static checks.
21638 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21639 the first time through the loop, since we know p0 < p1 then.
21640 This also avoids a gcc -Wstrict-overflow warning.
21642 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21643 leading to a memory leak, possible in functions like
21644 load_charset_map_from_file that can allocate an unbounded number
21645 of objects (Bug#8318).
21647 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21648 that could (at least in theory) be that large.
21650 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21651 This is less likely to overflow, and avoids undefined behavior if
21652 overflow does occur. All callers changed. Use strtoul to scan
21653 for the unsigned long integer.
21654 (pint2hrstr): Simplify and tune code slightly.
21655 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21657 * scroll.c (do_scrolling): Work around GCC bug 48228.
21658 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21660 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21661 This also avoids a warning with gcc -Wstrict-overflow.
21662 (validate_x_resource_name): Simplify count usage.
21663 This also avoids a warning with gcc -Wstrict-overflow.
21665 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21668 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21670 * process.c (Fmake_network_process): Use socklen_t, not int,
21671 where POSIX says socklen_t is required in portable programs.
21672 This fixes a porting bug on hosts like 64-bit HP-UX, where
21673 socklen_t is wider than int (Bug#8277).
21674 (Fmake_network_process, server_accept_connection):
21675 (wait_reading_process_output, read_process_output):
21678 * process.c: Rename or move locals to avoid shadowing.
21679 (list_processes_1, Fmake_network_process):
21680 (read_process_output_error_handler, exec_sentinel_error_handler):
21681 Rename or move locals.
21682 (Fmake_network_process): Define label "retry_connect" only if needed.
21683 (Fnetwork_interface_info): Fix pointer signedness.
21684 (process_send_signal): Add cast to avoid pointer signedness problem.
21685 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21686 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21688 Make tparam.h and terminfo.c consistent.
21689 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21690 Include tparam.h instead, since it declares them.
21691 * cm.h (PC): Remove extern decl; tparam.h now does this.
21692 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21693 * terminfo.c: Include tparam.h, to check interfaces.
21694 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21695 (tparam): Adjust signature to match interface in tparam.h;
21696 this removes some undefined behavior. Check that outstring and len
21697 are zero, which they always are with Emacs.
21698 * tparam.h (PC, BC, UP): New extern decls.
21700 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21701 (xftfont_open): Rename locals to avoid shadowing.
21703 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21704 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21705 (OTF_TAG_SYM): Omit macro if not needed.
21706 (ftfont_list): Remove unused local.
21707 (get_adstyle_property, ftfont_pattern_entity):
21708 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21709 Rename locals to avoid shadowing.
21711 * xfont.c (xfont_list_family): Mark var as initialized.
21713 * xml.c (make_dom): Now static.
21715 * composite.c (composition_compute_stop_pos): Rename local to
21717 (composition_reseat_it): Remove unused locals.
21718 (find_automatic_composition, composition_adjust_point): Likewise.
21719 (composition_update_it): Mark var as initialized.
21720 (find_automatic_composition): Mark vars as initialized,
21721 with a FIXME (Bug#8290).
21723 character.h: Rename locals to avoid shadowing.
21724 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21725 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21726 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21727 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21728 to avoid shadowing.
21730 * textprop.c (property_change_between_p): Remove; unused.

21747 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21749 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21750 clobbering (Bug#8298).
21751 * sysdep.c (sys_subshell): Likewise.
21752 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21754 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21755 This should get cleaned up, so that child_setup has the
21756 same signature on all platforms.
21758 * callproc.c (call_process_cleanup): Now static.
21759 (relocate_fd): Rename locals to avoid shadowing.
21761 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21890 some of which prompt warnings from gcc -Wbad-function-cast.
21891 (Fformat_time_string, Fencode_time, Finsert_char):

21920 (Fmemory_limit): Cast sbrk's returned value to char *.
21922 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21927 Use functions, not macros, for up- and down-casing (Bug#8254).
21928 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21929 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21930 to use the following functions instead of these macros.
21931 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21932 EMACS_INT, since callers assume the returned value fits in int.
21933 (upcase1): Likewise, for UPCASE_TABLE.
21934 (uppercasep, lowercasep, upcase): New static inline functions.
21935 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21945 (regex_compile, re_match_2_internal): Mark locals as initialized.
21946 (RETALLOC_IF): Define only if needed.
21947 (WORDCHAR_P): Likewise. This one is never needed, but is used
21948 only in a comment talking about a compiler bug, so put inside
21949 the #if 0 of that comment.
21950 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21951 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21977 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21978 New macros, so that the caller can use some names other than
21979 gcpro1, gcpro2, etc.
21980 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21982 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21983 argument, for consistency with GCPRO2_VAR, etc: it is now the
21984 prefix of the variable, not the variable itself. All uses
21986 * dired.c (directory_files_internal, file_name_completion):
21987 Rename locals to avoid shadowing.
21989 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21990 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21991 dired.c's scmp function, had undefined behavior.
21992 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21993 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21994 * buffer.h: ... to here, because these macros use current_buffer,
21995 and the new implementation with inline functions needs to have
21996 current_buffer in scope now, rather than later when the macros
21998 (downcase, upcase1): New static inline functions.
21999 (DOWNCASE, UPCASE1): Reimplement using these functions.
22000 This avoids undefined behavior in expressions like
22001 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22002 from race conditions in accessing the global variables
22003 case_temp1 and case_temp2.
22004 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22005 * lisp.h (case_temp1, case_temp2): Remove their decls.
22006 * character.h (ASCII_CHAR_P): Move from here ...
22007 * lisp.h: ... to here, so that the inline functions mentioned
22008 above can use them.
22010 * dired.c (directory_files_internal_unwind): Now static.
22012 * fileio.c (file_name_as_directory, directory_file_name):

22015 (file_name_as_directory): Use const pointers when appropriate.
22016 (Fexpand_file_name): Likewise. In particular, newdir might
22017 point at constant storage, so make it a const pointer.
22018 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22019 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22021 (Fset_file_times, Finsert_file_contents, auto_save_error):

22026 to avoid shadowing.
22028 * marker.c (bytepos_to_charpos): Remove; unused.
22030 * lisp.h (verify_bytepos, count_markers): New decls,
22031 so that gcc does not warn that these functions aren't declared.
22033 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22034 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22035 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22036 (copy_text): Remove unused local var.
22038 * filelock.c (within_one_second): Now static.
22039 (lock_file_1): Rename local to avoid shadowing.
22041 * buffer.c (fix_overlays_before): Mark locals as initialized.
22042 (fix_start_end_in_overlays): Likewise. This function should be
22043 simplified by using pointers-to-pointers, but that's a different
22045 (switch_to_buffer_1): Now static.
22046 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22047 (report_overlay_modification): Rename locals to avoid shadowing.
22049 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22050 Fix pointer signedness issue.
22051 (sys_subshell): Mark local as volatile if checking for lint,
22052 to suppress a gcc -Wclobbered warning that does not seem to be right.
22053 (MAXPATHLEN): Define only if needed.
22055 * process.c (serial_open, serial_configure): Move decls from here ...
22056 * systty.h: ... to here, so that they can be checked.
22058 * fns.c (get_random, seed_random): Move extern decls from here ...
22059 * lisp.h: ... to here, so that they can be checked.
22061 * sysdep.c (reset_io): Now static.
22062 (wait_for_termination_signal): Remove; unused.
22064 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22067 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22068 (DENSE_TABLE_SIZE): Remove; unused.
22069 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22070 (describe_map_tree):
22071 Rename locals to avoid shadowing.
22073 * keyboard.c: Declare functions static if they are not used elsewhere.
