3 Minor textprop integer cleanup.
4 * intervals.h, textprop.c (add_text_properties_from_list):
5 Return void, not int, since nobody uses the return value.
6 * textprop.c (validate_plist, add_properties, remove_properties)
7 (Fadd_text_properties):
8 Don't assume list length fits in int.
9 (interval_has_all_properties, interval_has_some_properties)
10 (interval_has_some_properties_list, add_properties, remove_properties)
11 (Fadd_text_properties, Fremove_text_properties)
12 (Fremove_list_of_text_properties, text_property_stickiness):
13 Use bool for booleans.

16 Reindent do-while as per GNU style.
18 2013-02-25 Eli Zaretskii <eliz@gnu.org>
20 Implement CLASH_DETECTION for MS-Windows.
22 * filelock.c [WINDOWSNT]: Include w32.h.
23 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
24 function of that name. Up-case the macro arguments.
25 (IS_LOCK_FILE): New macro.
26 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
27 (create_lock_file): New function, with body extracted from
29 [WINDOWSNT]: Implement lock files by writing a regular file with
30 the lock information as its contents.
31 (read_lock_data): New function, on Posix platforms just calls
33 [WINDOWSNT]: Read the lock info from the file.
34 (current_lock_owner): Call read_lock_data instead of calling
35 emacs_readlinkat directly.
36 (lock_file) [WINDOWSNT]: Run the file name through
39 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
40 just check if the process by that PID exists.
42 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
43 also present, as doing so will fail to error out if the file
46 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
48 * textprop.c (Fadd_text_properties, Fremove_text_properties)
49 (Fremove_list_of_text_properties): Skip all of the intervals in
50 the region between START and END that already have resp. don't
51 have the requested properties, not just the first one. Add
52 assertions that the loop afterwards always modifies the
53 properties. (Bug#13743)
55 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
57 * callint.c (Fcall_interactively): Use the right lexical environment
58 for `interactive' specs (bug#13811).

64 This is a followon simplification to the fix for Bug#13650.
65 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
66 (START_FILES): Remove. All uses removed.
67 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
68 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.

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

102 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
103 2012-07-10 patch to this file. Reported by Eli Zaretskii in
104 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
105 and diagnosed by Andreas Schwab in
106 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
108 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
110 Assume C89 or better.
111 * ralloc.c (SIZE, POINTER, NIL):
112 * vm-limit.c (POINTER):
113 Remove, replacing all uses with C89 equivalents. These old
114 symbols were present only for porting to pre-C89 platforms.
116 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
118 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
119 This avoids warning messages reported as part of Bug#13546.
121 2013-02-21 Ken Brown <kbrown@cornell.edu>
123 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
125 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
127 * sheap.c (report_sheap_usage): Prefer message1_nolog.
129 * keyboard.c (Qcommand_execute): New var.
130 (command_loop_1, read_char): Use it.
131 (Fcommand_execute): Remove, replace by an Elisp implementation.
132 (syms_of_keyboard): Adjust accordingly.
134 2013-02-19 Daniel Colascione <dancol@dancol.org>
136 * sheap.c (report_sheap_usage): Use message, not message1, so
137 that we don't try to create a buffer while we're in the middle
138 of dumping Emacs. Explain why.
140 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
141 * search.c (find_newline): Return byte position in bytepos.
143 (find_next_newline_no_quit, find_before_next_newline):
144 Add bytepos argument.

151 (get_visually_first_element, move_it_vertically_backward):
152 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
154 2013-02-19 Eli Zaretskii <eliz@gnu.org>
156 * w32proc.c (new_child): Avoid leaking handles if the subprocess
157 resources were not orderly released.
159 2013-02-17 Eli Zaretskii <eliz@gnu.org>
161 * xdisp.c (x_draw_vertical_border): For a window that is neither
162 the leftmost nor the rightmost, redraw both the left and the right
163 vertical borders. (Bug#13723)
165 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
167 * xml.c (init_libxml2_functions):
168 * sound.c (sound_warning):
169 * sheap.c (report_sheap_usage):
170 * process.c (wait_reading_process_output):
171 * msdos.c (XMenuActivate):
172 * macros.c (Fstart_kbd_macro, Fend_kbd_macro):
173 * keyboard.c (top_level_1):
174 * editfns.c (Fmessage, Fmessage_box):
175 * callint.c (Fcall_interactively):
176 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
178 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
180 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
181 * frame.c (syms_of_frame): ... to here.

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

218 value that is out of bounds.
219 (sys_accept): If fd is negative, do not set up the child_process
220 structure for reading.

232 (decode_mode_spec_coding, message3):
233 * xfaces.c (face_at_string_position): Use bool for booleans.
236 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
238 Fix AIX port (Bug#13650).
239 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
240 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
241 was #undeffed earlier, so it cannot be used as a macro here.
242 Use the constant and not the macro.
244 2013-02-15 Eli Zaretskii <eliz@gnu.org>
246 * w32proc.c (new_child): If no vacant slots are found in
247 child_procs[], make another pass looking for slots whose process
248 has exited or died. (Bug#13546)
250 * w32.c (sys_pipe): When failing due to file descriptors above
251 MAXDESC, set errno to EMFILE.
252 (_sys_read_ahead): Update cp->status when failing to read serial
253 communications input, so that the status doesn't stay at
254 STATUS_READ_IN_PROGRESS. (Bug#13546)
256 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
258 * gtkutil.c (tb_size_cb): New function.
259 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
261 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
263 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
266 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
268 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
270 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
272 * font.c (font_range): Add pos_byte argument. Adjust comment
274 * font.h (font_range): Adjust prototype.
275 * composite.c (autocmp_chars): Pass byte position to font_range.
276 Break long line. Remove useless prototype and format comment.
278 2013-02-13 Glenn Morris <rgm@gnu.org>
280 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
282 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
284 Improve AIX port some more (Bug#13650).
285 With this, it should be as good as it was in 23.3, though it's
286 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
287 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
288 * unexaix.c (start_of_text): Remove.
289 (_data, _text): Declare as char[], not int, as AIX manual suggests.
290 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
291 (orig_load_scnptr, orig_data_scnptr):
292 Now off_t, not long, since they are file offsets.
293 (make_hdr): Use _data, not start_of_data ().
294 This is the key part of the fix.
295 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
296 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
298 * pre-crt0.c (data_start): Initialize to 1.
299 This ports to compilers that optimize the external declaration
300 'int x = 0;' as if it were 'int x;' to shrink the executable.
302 Improve AIX port (Bug#13650).
303 This doesn't fix the bug, but it makes progress: Emacs builds now.
304 * unexaix.c: Include inttypes.h, stdarg.h.
305 (report_error, report_error_1): Mark as _Noreturn.
306 (report_error): Don't report the wrong errno.
307 (report_error_1): Now varargs. All callers changed.
308 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
309 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
310 (write_ptr): Use %p to print address rather than %lx and a cast
311 to unsigned long. Grow buffer a bit, to be safer.
313 2013-02-13 Eli Zaretskii <eliz@gnu.org>
315 * bidi.c (bidi_resolve_neutral): After finding the next
316 non-neutral character, accept NEUTRAL_ON type as well, because
317 directional control characters, such as LRE and RLE, have their
318 type converted to that by bidi_resolve_weak. This avoids aborts
319 when LRE/RLE follows a run of neutrals.
320 (bidi_move_to_visually_next): Assert that return value of
321 bidi_peek_at_next_level is non-negative. Negative values will
324 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
326 Minor getenv-related fixes.
327 * callproc.c (Fcall_process_region) [!DOS_NT]:
328 Avoid unnecessary duplicate call to getenv.
329 * callproc.c (init_callproc):
330 * dispnew.c (init_display):
331 * sysdep.c (sys_subshell):
332 Omit unnecessary cast of getenv or egetenv.
334 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
336 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
339 2013-02-12 Eli Zaretskii <eliz@gnu.org>
341 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
343 (display_line): Set w->region_showing to the value of
344 it->region_beg_charpos, not to -1. This fixes redisplay
345 optimization when cursor is moved up after M->. (Bug#13623)
347 (try_scrolling): Scroll text up more if point is too close to ZV
348 and inside the scroll margin. This makes sure point is moved
349 outside the scroll margin in these cases.
351 * window.h (struct window): region_showing can no longer be
354 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
356 Tune by using memchr and memrchr.
357 * doc.c (Fsnarf_documentation):
358 * fileio.c (Fsubstitute_in_file_name):
359 * search.c (find_newline, scan_newline):
360 * xdisp.c (pos_visible_p, display_count_lines):
361 Use memchr and memrchr rather than scanning byte-by-byte.
362 * search.c (find_newline): Rename from scan_buffer.
363 Omit first arg TARGET, as it's always '\n'. All callers changed.
365 Clean up read_key_sequence a tiny bit more.
366 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
367 (read_key_sequence): Remove unused locals.
369 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
371 Clean up read_key_sequence a bit; reread active keymaps after first event.
372 * keyboard.c (read_char, read_char_x_menu_prompt)
373 (read_char_minibuf_menu_prompt):
374 Replace nmaps+maps with a single `map' arg.
375 (follow_key): Operate on a single map.
376 (active_maps): New function.
377 (test_undefined): Also return true for nil bindings.
378 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
379 a single (composed) keymap. Remember `first_event' to choose the right
380 set of active keymaps. Recompute the set of keymaps after receiving
381 the first event. Remove GOBBLE_FIRST_EVENT.
382 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
383 * keyboard.h (read_char): Update declaration.
384 * lread.c (read_filtered_event): Adjust call to read_char.
386 2013-02-11 Eli Zaretskii <eliz@gnu.org>
388 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
389 Don't use the limitation on backwards movement when lines are truncated
390 in the window. (Bug#13675)
392 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
394 * marker.c (set_marker_internal): If desired position is passed
395 as a marker, avoid call to buf_charpos_to_bytepos.
396 * window.c (Fset_window_point): Omit redundant type checking.
397 (Fset_window_start): Likewise. Format comment.
398 (window_scroll_pixel_based): Use set_marker_restricted_both
399 with character and byte positions obtained from an iterator.
400 (Fset_window_configuration): Use set_marker_restricted_both.
401 * xdisp.c (message_dolog): Likewise.
403 2013-02-10 Eli Zaretskii <eliz@gnu.org>
405 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
406 When text lines are longer than window's screen lines, don't move back
407 too far. This speeds up some redisplay operations. (Bug#13675)
409 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
411 * syntax.c (scan_sexps_forward): Fix byte position calculation
412 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
414 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
416 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
419 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
421 Minor hashing refactoring.
422 * fns.c (SXHASH_REDUCE): Move to lisp.h.
423 (sxhash_float): Return EMACS_UINT, for consistency with the other
425 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
426 non-static inline function and therefore can't use static vars.
427 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
428 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
429 with the other hash functions.
431 2013-02-09 Eli Zaretskii <eliz@gnu.org>
433 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
434 XXXXXX part of the temporary file pattern is not downcased even
435 when w32-downcase-file-names is non-nil. (Bug#13661)
437 * xdisp.c (decode_mode_spec): Remove handling of %t.
439 * msdos.c (careadlinkatcwd): Remove.
441 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
443 * lread.c (skip_dyn_bytes): New function (bug#12598).

445 (load_each_byte): Remove. Update users.
447 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
449 * search.c (scan_buffer): Calculate end byte position just once.

476 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
478 * coding.c (Fdefine_coding_system_internal): Use AREF where
479 argument is known to be a vector.

484 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
486 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
489 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
490 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
491 updateCollectionBehaviour.
493 * nsterm.m (NEW_STYLE_FS): Remove.
494 (ns_last_use_native_fullscreen): New variable.
495 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
496 (x_set_window_size): Do not take title bar and tool bar into account
497 if isFullscreen returns YES.
498 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
499 (check_native_fs): New function.
500 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
501 (ns_term_init): Remove NEW_STYLE_FS.
502 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
503 and tool bar if isFullscreen returns NO.
504 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
505 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
507 (window:willUseFullScreenPresentationOptions:): New method.
508 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
509 Hide toolbar if not enabled (Bug#13444).
510 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
511 Restore tool bar if enabled, hide it otherwise (Bug#13444).
512 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
513 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
514 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
515 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
516 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
517 (syms_of_nsterm): Add ns-use-native-fullscreen.
519 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
521 * fileio.c (Qchoose_write_coding_system): Now static.
523 2013-02-04 Eli Zaretskii <eliz@gnu.org>
525 * xdisp.c (window_buffer_changed): region_showing can be negative,
526 which still means region is being displayed.
527 (redisplay_internal): Resurrect code that forced redisplay of the
528 whole window when showing region and the mark has changed.
529 Record the new mark position to allow redisplay optimizations.
530 (display_line): If it->region_beg_charpos is non-zero, set the
531 window's region_showing member to -1. (Bug#13623) (Bug#13626)
533 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
534 not bitfield of 1 bit.
536 2013-02-03 Daniel Colascione <dancol@dancol.org>
538 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
539 daemon mode works on cygw32 when Emacs is installed and not just
542 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
544 Avoid file time stamp bug on MS-Windows (Bug#13149).
545 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
546 as FAT32 doesn't update time stamps when truncating them.
547 Also, check that a file time stamp is not a multiple of 100 ns;
548 this should catch all instances of the problem on MS-Windows,
549 as its native file system resolution is 100 ns or worse, and
550 checking for a non-multiple of 100 ns should impose only a small
551 overhead on systems with ns resolution.
553 2013-02-02 Eli Zaretskii <eliz@gnu.org>
555 Avoid encoding file names on MS-Windows when they need to be run
556 through dostounix_filename.
557 * w32.c (normalize_filename): Accept an additional argument
558 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
559 downcase it even if w32-downcase-file-names is non-nil.
560 (dostounix_filename): Accept an additional argument MULTIBYTE and
561 pass it to normalize_filename.
562 (emacs_root_dir): Adjust.
564 * msdos.h (dostounix_filename): Adjust prototype.
566 * w32.h (dostounix_filename): Adjust prototype.
568 * msdos.c (dostounix_filename): Accept an additional argument and
570 (init_environment): Adjust callers of dostounix_filename.
572 * fileio.c (Ffile_name_directory, file_name_as_directory)
573 (directory_file_name, Fexpand_file_name)
574 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
576 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
578 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
579 variables, as egetenv is case-insensitive for DOS_NT.
581 * dired.c (file_name_completion): Don't call Fdirectory_file_name
582 with an encoded file name.
584 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
585 Adjust calls to dostounix_filename.
587 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
589 * unexw32.c (unexec): Adjust call to dostounix_filename.
591 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
593 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
596 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
599 * callproc.c (Fcall_process): Make sure program name in PATH and
600 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
601 is passed to exec/spawnve, which fails unless the file-name
604 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
605 even if w32-quote-process-args is nil.
607 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
609 Fix timestamp bug when write-region appends nothing (Bug#13149).
610 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
611 the file's time stamp doesn't change if Emacs happens to write nothing
612 to the file, and on a buggy file system this could cause Emacs to
613 incorrectly infer that the file system doesn't have the bug.
614 Avoid this problem by inhibiting the inference in this case.
616 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
618 * window.h (struct window): Convert base_line_number, base_line_pos
619 and column_number_displayed members from Lisp_Object to ptrdiff_t.
620 Convert region_showing member from Lisp_Object to bitfield.
621 Remove sequence_number member. Adjust comments.
622 * window.c (sequence_number): Remove.
623 (make_window): Initialize column_number_displayed.
624 * print.c (print_object): Follow the printed representation of
625 frames and print window pointer to distinguish between windows.
626 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
627 * xdisp.c (wset_base_line_number, wset_base_line_pos)
628 (wset_column_number_displayed, wset_region_showing): Remove.
629 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
630 (try_scrolling, try_cursor_movement, redisplay_window)
631 (try_window_reusing_current_matrix, try_window_id, display_line)
632 (display_mode_lines, decode_mode_spec): Adjust users.
633 * .gdbinit (pwinx): Do not print sequence_number.
635 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
637 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
638 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
639 * dired.c: Include <fcntl.h>.
640 (open_directory): New function, which uses open and fdopendir
641 rather than opendir. DOS_NT platforms still use opendir, though.
642 (directory_files_internal, file_name_completion): Use it.
643 (file_attributes): New function, with most of the old Ffile_attributes.
644 (directory_files_internal, Ffile_attributes): Use it.
645 (file_attributes, file_name_completion_stat): First arg is now fd,
646 not dir name. All uses changed. Use fstatat rather than lstat +
648 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
649 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
650 (emacs_readlinkat): New function, with much of the old
651 Ffile_symlink_p, but with an fd argument for speed.
652 It uses readlinkat rather than careadlinkatcwd, so that it
653 need not assume the working directory.
654 (Ffile_symlink_p): Use it.
655 * filelock.c (current_lock_owner): Use emacs_readlinkat
656 rather than emacs_readlink.
657 * lisp.h (emacs_readlinkat): New decl.
658 (READLINK_BUFSIZE, emacs_readlink): Remove.
659 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
660 (emacs_norealloc_allocator, emacs_readlink): Remove.
661 This stuff is moved to fileio.c.
662 * w32.c (fstatat, readlinkat): New functions.
663 (careadlinkat): Don't check that fd == AT_FDCWD.
664 (careadlinkatcwd): Remove; no longer needed.
666 2013-01-31 Glenn Morris <rgm@gnu.org>
668 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
669 (Fwrite_region): Update for new choose_write_coding_system args.
670 Move the last piece of choose_write_coding_system here. (Bug#13522)
671 (syms_of_fileio): Add choose-write-coding-system.
673 2013-01-30 Eli Zaretskii <eliz@gnu.org>
675 * w32.c (sys_open): Zero out the flags for the new file descriptor.
676 (sys_close): Zero out the flags for the file descriptor before
677 closing it. (Bug#13546)
679 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
680 (logon_network_drive, stat_worker, symlink, chase_symlinks):
681 Use CharNextExA and CharPrevExA to iterate over file names encoded in
684 * w32.c (w32_get_long_filename, init_environment, readlink):
685 Support file names encoded in DBCS codepages.
686 (readlink): Use the current file-name-coding-system, not the ANSI
687 codepage, to decode and handle targets of symlinks.
689 2013-01-28 Eli Zaretskii <eliz@gnu.org>
691 * w32.c (opendir): Now accepts a 'const char *'.
693 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
695 Remove obsolete redisplay code. See the discussion at
696 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
697 * dispnew.c (preemption_period, preemption_next_check): Remove.
698 (Vredisplay_preemption_period): Likewise.
699 (update_frame, update_single_window, update_window, update_frame_1):
700 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
701 used, following the 2012-06-22 change.
703 2013-01-25 Eli Zaretskii <eliz@gnu.org>
705 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
707 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
709 * font.c (num_fonts): Remove the leftover from old
710 debugging code. Adjust comment style here and there.
711 * insdel.c (insert_1): Remove.
712 * lisp.h (insert_1): Remove prototype.
713 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
715 2013-01-25 Eli Zaretskii <eliz@gnu.org>
717 * w32.c (max_filename_mbslen): New function.
718 (normalize_filename, readdir): Use it to detect locales where ANSI
719 encoding of file names uses a double-byte character set (DBCS).
720 If a DBCS encoding is used, advance by characters using
721 CharNextExA, instead of incrementing a 'char *' pointer.
722 Use _mbslwr instead of _strlwr. (Bug#13515)
724 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
725 request of memory reservation to 1.7GB. (Bug#13065)
727 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
729 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
730 at check_extra_latin label. (Bug#13505)
732 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
734 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
735 Avoid redundant calls to strlen.
737 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
739 Drop async_visible and async_iconified fields of struct frame.
740 This is possible because async input is gone; for details, see
741 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
742 * frame.h (struct frame): Remove async_visible and async_iconified
743 members, convert garbaged to unsigned bitfield. Adjust comments.
744 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
745 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
746 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
747 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
748 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
750 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
751 properly. Likewise for obscured.
753 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
756 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
758 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
760 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
761 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
763 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
765 * xdisp.c (message2, message2_nolog): Remove functions.
766 (message3, message3_nolog): Extract nbytes and multibyteness directly
767 from the string. Change all callers.
768 (message3_nolog): Don't set message_enable_multibyte since set_message
769 will reset it anyway.
770 (message1, message1_nolog): Use message3.
771 (vmessage): Use a stack allocated buffer rather than f->message_buf.
772 (with_echo_area_buffer): Remove last two arguments. Update all callers.
773 (set_message): Drop all but the second arg, which has to be a string.
774 (set_message_1): Simplify now that we know that a1 is NULL and the
775 second arg is a string.
776 * frame.h (struct frame): Remove `message_buf' field.
777 Use glyphs_initialized_p instead.
778 (FRAME_MESSAGE_BUF): Remove macro.
779 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
780 * lisp.h (message2, message2_nolog): Remove declarations.
781 (message3, message3_nolog): Update declarations.
782 * keyboard.c (read_char_minibuf_menu_text)
783 (read_char_minibuf_menu_width): Remove vars.
784 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
785 to correctly handle multibyte strings.
786 * frame.c (delete_frame): Don't free message_buf any more.
787 * editfns.c (message_text, message_length): Remove vars.
788 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
789 * fileio.c (auto_save_error): Use message3 instead of message2.
790 * dispnew.c (adjust_frame_message_buffer): Remove function.
792 2013-01-23 Eli Zaretskii <eliz@gnu.org>
794 * w32term.c (w32fullscreen_hook): Account correctly for the screen
795 real estate used for the tool bar and the menu bar.
797 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
799 * insdel.c (prepare_to_modify_buffer): Force redisplay if
800 hidden buffer is prepared to modification (Bug#13164).
802 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
804 * window.h (struct window): Change window_end_valid member from
805 Lisp_Object to a bitfield. Adjust comments.
806 (wset_window_end_valid): Remove.
807 * window.c (adjust_window_count): Clear window_end_valid.
808 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
809 (Fwindow_line_height, set_window_buffer, Frecenter)
810 (Fsplit_window_internal, Fdelete_other_windows_internal)
811 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
812 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
813 * xdisp.c (check_window_end, reconsider_clip_changes)
814 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
815 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
816 (find_first_unchanged_at_end_row, try_window_id): Likewise.
818 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
820 * xdisp.c (mark_window_display_accurate): Simplify the loop
821 assuming that the only one of vchild, hchild or buffer window
822 slots is non-nil. Call mark_window_display_accurate_1 for
823 the leaf windows only.
824 (mark_window_display_accurate_1): Always assume leaf window.
827 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
829 * emacs.c (Qkill_emacs_hook): Now static.
831 * fileio.c (Finsert_file_contents): Simplify.
832 Remove unnecessary assignments and tests.
834 2013-01-21 Eli Zaretskii <eliz@gnu.org>
836 * w32.c (acl_set_file): Don't test for errors unless
837 set_file_security returns FALSE. Avoids spurious errors when
840 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
842 * fileio.c (Finsert_file_contents): Revert code introduced at
843 2013-01-18 in favor of the simpler and generally better fix.
844 Save stack space by removing 'buffer' and reusing 'read_buf'
847 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
849 * lisp.h (eabs): Define unconditionally (Bug#13419).
850 The old "#if !defined (eabs)" was an unnecessary revenant of back
851 when this macro was called "abs". Document 'eabs' better.
853 2013-01-19 Glenn Morris <rgm@gnu.org>
855 * fns.c (Frandom): Doc fix.
857 2013-01-19 Eli Zaretskii <eliz@gnu.org>
859 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
860 segfault when there are lots of overlays.
862 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
863 when there are lots of overlays.
864 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
865 for the details and a way to reproduce.
867 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
869 * fileio.c: Use O_APPEND to append.
870 This corresponds better to the natural interpretation of "append",
871 and avoids the need to open the output file twice, or to invoke
872 lseek when APPEND is neither nil nor a number.
873 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
874 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
875 file possibly twice, and lseeking to its end; this avoids the
876 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
877 at the same time: the combination is never needed and apparently
878 it doesn't work with DOS_NT.
880 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
881 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
883 Allow floating-point file offsets.
884 Problem reported by Vitalie Spinu in
885 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
886 * fileio.c (emacs_lseek): Remove.
887 (file_offset): New function.
888 (Finsert_file_contents, Fwrite_region): Use it.
890 2013-01-19 Chong Yidong <cyd@gnu.org>
892 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
893 aborting on Fsignal (Bug#13289).
895 2013-01-19 Eli Zaretskii <eliz@gnu.org>
897 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
898 set_file_security as failure due to insufficient privileges.
899 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
900 (fstat): Return owner and group like 'stat' and 'lstat' do.
902 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
904 Work around bug in CIFS and vboxsf file systems (Bug#13149).
905 The bug was observed on Ubuntu operating inside a virtual machine,
906 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
907 The workaround introduces a race condition on non-buggy hosts,
908 but it's an unlikely race and anyway there's a nearly identical
909 nearby race that can't be fixed.
910 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
912 (Fwrite_region): Test for file system time stamp bug.
913 (init_fileio): New function.
914 * lisp.h (init_fileio): Declare it.
915 * emacs.c (main): Call it.
917 * fileio.c (Finsert_file_contents): Simplify new diagnostic
918 and make it more consistent with other stat-failure diagnostics.
920 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
922 Fix crash when inserting data from non-regular files.
923 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
924 for the error description produced by valgrind.
925 * fileio.c (read_non_regular): Rename to read_contents.
926 Free Lisp_Save_Value object used to pass parameters.
927 (read_non_regular_quit): Rename to read_contents_quit.
928 (Finsert_file_contents): Redesign internal file reading loop to adjust
929 gap and end positions after each read and so help make_gap to work
930 properly. Do not signal an I/O error too early and so do not leave
931 not yet decoded characters in a buffer, which was the reason of
932 redisplay crash. Use list2 to build return value. Adjust comments.
934 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
936 Close a race when statting and reading files (Bug#13149).
937 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
938 This avoids a race if the file is renamed between stat and open.
939 This race is not the problem originally noted in Bug#13149;
940 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
942 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
944 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
945 objects, related functions and macros.
946 (make_save_value): Adjust prototype.
947 (make_save_pointer): New prototype.
948 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.

1133 which has already arranged for that.
1134 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

1155 right-fringe-width, scroll-bar-width and buffer-display-count.
1156 Use Qstringp for default-directory, buffer-file-name,
1157 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1158 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

1248 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1250 * w32.c (unsetenv): Set up the string passed to _putenv
1252 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1253 for the bug this caused.

1274 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1276 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1277 (xg_update_menubar): Update title only if

1279 (xg_update_submenu): Skip tearoff only if
1280 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1281 (xg_initialize): Initialize xg_detached_menus only if
1282 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1284 * xterm.h (struct x_output): Surround handlebox_widget with
1285 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1286 toolbar_in_hbox is bool.
1288 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1290 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.

1322 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1324 * fileio.c (file_name_as_directory, directory_file_name):
1325 Accept an additional argument MULTIBYTE to indicate whether the input C
1326 came from a multibyte or a unibyte Lisp string; all callers
1327 adjusted. Don't assume the input string is always multibyte.
1329 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1330 don't ENCODE_FILE them, and return a unibyte string if the input
1332 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1333 don't assume the input strings will always be multibyte. If the
1334 input strings are multibyte, decode strings obtained from C
1337 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1339 * lisp.h (toplevel): Add two notices to the comment about
1340 defining a new Lisp data type.

1348 * keyboard.c (record_asynch_buffer_change): Initialize an event
1349 only if it's really needed.
1350 * frame.h (enum output_method): Remove output_mac member since
1351 it's a leftover from the deleted code.
1352 * frame.c (Fframep): Adjust user here ...
1353 * terminal.c (Fterminal_live_p): ... and here.
1354 * coding.c (Qmac): Now here because it's only used to denote
1355 end-of-line encoding type.
1356 (syms_of_coding): DEFSYM it.
1357 * frame.h (Qmac): Remove duplicated declaration.
1359 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1361 * window.c (select_window_1): Now static, since it's used only here.
1363 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1365 * window.c (window_body_cols): Subtract display margins from the
1366 window body width on TTYs as well. See
1367 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1368 for the original report.
1370 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1372 * xdisp.c (redisplay_window): Remove inner local variable
1373 because the outer shadowed one has the same meaning.
1374 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1376 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1377 (xg_create_tool_bar): Adjust users.
1379 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1381 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1382 * buffer.c (Fget_buffer_create): Use it to set compact field of
1383 struct buffer_text to avoid accessing an uninitialized value
1384 when compact_buffer is called for the first time.
1385 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1386 (Fset_buffer_modified_p): Use buffer_window_count to check
1387 whether the buffer is displayed in some window.

1392 * w32.c (acl_set_file): If setting the file security descriptor
1393 fails, and the new DACL is identical to the existing one, silently

1395 own files without having the necessary privileges for setting
1396 security descriptors.
1398 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1400 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1401 after WaitForSingleObject returns normally. This expedites reader
1402 thread shutdown when delete_child triggers it.
1403 (reap_subprocess): More accurate commentary for why we call
1404 delete_child only when cp->fd is negative.
1406 * w32.c (sys_close): Do not call delete_child on a subprocess
1407 whose handle is not yet closed. Instead, set its file descriptor
1408 to a negative value, so that reap_subprocess will call
1409 delete_child on that subprocess when its SIGCHLD arrives.
1410 This avoids closing handles used for communications between sys_select
1411 and reader_thread, which doesn't give sys_select a chance to
1412 notice that the process exited and invoke the SIGCHLD handler for

1433 * fileio.c (Finsert_file_contents): Doc fix.
1435 * w32proc.c (new_child, delete_child, find_child_pid): For a
1436 subprocess, consider its slot being in use as long as its process
1437 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1438 slot when a new process is started immediately after killing
1439 another one, without waiting enough time for the first process to
1440 be reaped and resources allocated for it be orderly freed.
1442 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1444 2012-12-21 Chong Yidong <cyd@gnu.org>

1455 Remove now unused argument FNAME; all callers changed.
1456 (get_file_owner_and_group): Remove now unused argument FNAME; all
1459 2012-12-21 Chong Yidong <cyd@gnu.org>
1461 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1462 error for invalid chars, don't check for a nil return value.

1493 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1494 Rename 4th argument since it may be buffer or string. Adjust comment.
1495 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1497 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1499 * coding.c (Fdetect_coding_region): Do not check start and end with
1500 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1501 (code_convert_region): Likewise.
1503 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1505 * w32.c (acl_get_file, acl_set_file): Run the file name through

1522 * window.c (select_window_1): New func, extracted from select_window.
1523 (select_window): Use it.
1524 * window.h (select_window_1): Declare.

1550 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1552 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1553 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1554 for some of that bug's symptoms can now cause Emacs to abort.
1555 Remove the workaround.
1556 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1557 The bug that caused SIGCHLD to get lost has been fixed, and the
1558 workaround for it can now cause Emacs to abort.
1560 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1562 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1600 * lisp.h (internal_delete_file): Adjust prototype.
1602 * callproc.c (Fcall_process): Don't overwrite infile with result
1604 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1605 asynchronous subprocess, record the name of the input file name,
1607 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1608 delete the file, record it as pending deletion when the subprocess
1611 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1613 * editfns.c [HAVE_PWD_H]: Include grp.h.

1619 Fix permissions bugs with setgid directories etc. (Bug#13125)
1620 * dired.c (Ffile_attributes): Return t as the 9th attribute,

1631 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1633 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1634 try to get accurate owner and group information from NT file
1635 security APIs. This is to make most callers of 'stat' and
1636 'lstat', which don't need that information, much faster.
1638 * dired.c (Ffile_attributes) [WINDOWSNT]:
1639 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1640 owner and group information from 'lstat'.
1642 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1644 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1645 as that confuses set-auto-coding, so insist on the head-read

1671 files, fixing a regression from 24.2.
1672 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1674 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1676 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1677 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1678 Remove unnecessary S_ISLNK test, as (contra the comments) this
1679 function can't copy symlinks. Improve quality of error message
1680 when attempting to copy files that are neither regular files nor

1693 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1694 the dumped Emacs is not a sparse file, greatly improving Cygwin
1695 "make bootstrap" performance.

1699 * inotify.c (inotify_callback): Generate an Emacs event for every
1700 incoming inotify event.
1702 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1704 * xdisp.c (handle_face_prop): Fix logic of computing
1705 it->start_of_box_run_p.
1706 (append_space_for_newline): If the glyph row is R2L, reset the
1707 iterator's end_of_box_run_p flag before prepending the space glyph.
1708 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1709 iterator's start_of_box_run_p flag before prepending the stretch.

1711 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1712 left_box_line_p and right_box_line_p flags of the glyph for R2L
1713 glyph rows. (Bug#13011)

1763 (hinst): Remove unneeded extern declaration.
1764 (_start): Remove initialization of above variables; remove

1905 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1907 * w32.c (unsetenv): Return 0 if the input string is too long.
1909 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1911 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1912 * alloc.c (xputenv): New function.
1913 * dbusbind.c (Fdbus_init_bus):
1915 * xterm.c (x_term_init):
1916 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1917 * editfns.c (initial_tz): Move static var decl up.

1919 (init_editfns): Initialize these two static vars.
1920 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1921 Save old TZ value on stack, if it's small.
1922 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1923 instead, use xputenv+unsetenv to set and restore TZ.
1924 (environbuf): Remove static var. All uses removed.
1925 (Fset_time_zone_rule): Do not save TZ and environ;
1926 no longer needed here.
1927 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1928 Move to inside set_time_zone_rule; they don't need file scope any more.
1929 (set_time_zone_rule): Maintain the TZ=value string separately.
1930 (syms_of_editfns): Don't initialize initial_tz;
1931 init_editfns now does it.
1932 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1933 * lisp.h (xputenv): New decl.
1935 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1937 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1939 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1941 * w32.c (unsetenv, sys_putenv): New functions.
1943 2012-12-08 Chong Yidong <cyd@gnu.org>
1945 * editfns.c (Finsert_char): Make the error message more
1946 informative (Bug#12992).
1948 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1950 Simplify get_lim_data.
1951 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1952 Remove USG and vlimit methods; no longer used these days.
1953 Add #error catchall just in case.
1955 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1956 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1957 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1958 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1959 (deleted_pid_list, Fdelete_process, create_process)
1960 (record_child_status_change, handle_child_signal, deliver_child_signal)
1961 (init_process_emacs, syms_of_process):
1962 Assume SIGCHLD is defined.
1963 (parse_signal): Remove. All uses removed.
1964 (abbr_to_signal): New static function.
1965 (Fsignal_process): Use it to convert signal names to ints.
1966 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1967 kill (getpgrp (), ...).
1968 (emacs_sigaction_init): Assume SIGCHLD is defined.
1969 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1970 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1971 * syssignal.h (EMACS_KILLPG): Remove.
1972 All uses replaced by 'kill' with a negative pid.
1973 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1974 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1976 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1978 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1979 This will cause a production Emacs to dump core instead of
1982 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1984 * frame.c (make_frame): Do not set window's buffer to t.
1985 * window.c (Fsplit_window_internal): Likewise. Previously it was
1986 used to indicate that the window is being set up. Now we use
1987 set_window_buffer for all new windows, so the condition in ...
1988 (Fset_window_buffer): ... is always true and can be removed.
1990 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1992 Convenient macro to check whether the buffer is hidden.
1993 * buffer.h (BUFFER_HIDDEN_P): New macro.
1994 * frame.c (make_frame): Use it. Adjust comment.
1995 * buffer.c (candidate_buffer): New function.
1996 (Fother_buffer, other_buffer_safely): Use it.
1998 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2000 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2001 if the child process is still running. Instead, exit the wait
2002 loop and return zero. (Bug#13086)
2004 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2006 * frame.h (x_char_width, x_char_height): Remove prototypes.
2007 * w32term.h (x_char_width, x_char_height): Likewise.
2008 * xfns.c (x_char_width, x_char_height): Remove.
2009 * w32fns.c (x_char_width, x_char_height): Likewise.

2019 Fix a recently-introduced delete-process race condition.
2020 * callproc.c, process.h (record_kill_process):
2021 New function, containing part of the old call_process_kill.
2022 (call_process_kill): Use it.
2023 This does not change call_process_kill's behavior.
2024 * process.c (Fdelete_process): Use record_kill_process to fix a
2025 race condition that could cause Emacs to lose track of a child.
2027 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2029 Avoid code duplication between prev_frame and next_frame.
2030 * frame.c (candidate_frame): New function. Add comment.
2031 (prev_frame, next_frame): Use it. Adjust comment.
2033 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2035 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2036 fails, signal an error instead of continuing with an empty
2038 Encode expanded temp file pattern before passing it to mkstemp or
2041 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2042 Encode the file name before passing it to dostounix_filename, in
2043 case it will downcase it (under w32-downcase-file-names).
2046 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2048 Minor call-process cleanups.
2049 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2050 at the same time as other platforms, to simplify analysis.
2051 No need for fd0_volatile since we have synch_process_fd.
2052 Avoid needless emacs_close; arg is always negative.
2054 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2056 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2059 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2061 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2062 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2063 and mouse_face_hidden members to a bitfields.
2064 * frame.h (struct frame): Remove set-but-not-used space_width member.
2065 (FRAME_SPACE_WIDTH): Remove.
2066 * nsterm.m, w32term.c, xterm.c: Adjust users.
2067 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2068 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2069 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2070 members to a bitfields.
2072 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2074 Don't let call-process be a zombie factory (Bug#12980).
2075 Fixing this bug required some cleanup of the signal-handling code.
2076 As a side effect, this change also fixes a longstanding rare race
2077 condition whereby Emacs could mistakenly kill unrelated processes,
2078 and it fixes a bug where a second C-g does not kill a recalcitrant
2079 synchronous process in GNU/Linux and similar platforms.
2080 The patch should also fix the last vestiges of Bug#9488,
2081 a bug which has mostly been fixed on the trunk by other changes.
2082 * callproc.c, process.h (synch_process_alive, synch_process_death)
2083 (synch_process_termsig, sync_process_retcode):
2084 Remove. All uses removed, to simplify analysis and so that
2085 less consing is done inside critical sections.
2086 * callproc.c (call_process_exited): Remove. All uses replaced
2087 with !synch_process_pid.
2088 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2089 These take the role of what used to be in unwind-protect arg.
2091 (block_child_signal, unblock_child_signal):
2092 New functions, to avoid races that could kill innocent-victim processes.
2093 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2094 (call_process_kill): Record killed processes as deleted, so that
2095 zombies do not clutter up the system. Do this inside a critical
2096 section, to avoid a race that would allow the clutter.
2097 (call_process_cleanup): Fix code so that the second C-g works again
2098 on common platforms such as GNU/Linux.
2099 (Fcall_process): Create the child process in a critical section,
2100 to fix a race condition. If creating an asynchronous process,
2101 record it as deleted so that zombies do not clutter up the system.
2102 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2103 light of these changes. Omit unnecessary call to emacs_close
2104 before failure, as the unwind-protect code does that.
2105 * callproc.c (call_process_cleanup):
2106 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2107 * process.c (record_deleted_pid): New function, containing
2108 code refactored out of Fdelete_process.
2109 (Fdelete_process): Use it.
2110 (process_status_retrieved): Remove. All callers changed to use
2111 child_status_change.
2112 (record_child_status_change): Remove, folding its contents into ...
2113 (handle_child_signal): ... this signal handler. Now, this
2114 function is purely a handler for SIGCHLD, and is not called after
2115 a synchronous waitpid returns; the synchronous code is moved to
2116 wait_for_termination. There is no need to worry about reaping
2117 more than one child now.
2118 * sysdep.c (get_child_status, child_status_changed): New functions.
2119 (wait_for_termination): Now takes int * status and bool
2120 interruptible arguments, too. Do not record child status change;
2121 that's now the caller's responsibility. All callers changed.
2122 Reimplement in terms of get_child_status.
2123 (wait_for_termination_1, interruptible_wait_for_termination):
2124 Remove. All callers changed to use wait_for_termination.
2125 * syswait.h: Include <stdbool.h>, for bool.
2126 (record_child_status_change, interruptible_wait_for_termination):
2128 (record_deleted_pid, child_status_changed): New decls.
2129 (wait_for_termination): Adjust to API changes noted above.
2131 * bytecode.c, lisp.h (Qbytecode): Remove.
2132 No longer needed after 2012-11-20 interactive-p changes.
2134 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2136 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2137 the scroll margin, move point outside the margin. (Bug#13055)
2139 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2141 * gtkutil.c (my_log_handler): New function.
2142 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2144 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2146 * lisp.h (modify_region): Rename to...
2147 (modify_region_1): ...new prototype.
2148 * textprop.c (modify_region): Now static. Adjust users.
2149 * insdel.c (modify_region): Rename to...
2150 (modify_region_1): ...new function to work with current buffer.
2151 Adjust comment and users. Use true and false for booleans.
2153 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2155 * alloc.c (free_save_value): New function.
2156 (safe_alloca_unwind): Use it.
2157 * lisp.h (free_save_value): New prototype.
2158 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2160 (save_excursion_restore): Adjust to match saved data structure.
2161 Use free_save_value to offload some work from GC. Drop obsolete
2164 2012-12-03 Chong Yidong <cyd@gnu.org>
2166 * fileio.c (Vauto_save_list_file_name): Doc fix.
2168 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2170 * w32fns.c: Remove prototype of atof.
2171 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2173 (file_dialog_callback): Make it UINT_PTR.
2175 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2178 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2179 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2182 2012-12-03 Glenn Morris <rgm@gnu.org>
2184 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2186 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2188 Fix xpalloc confusion after memory is exhausted.
2189 * alloc.c (xpalloc): Comment fix.
2190 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2191 and signals an error, do not clear charset_table_size, as
2192 charset_table is still valid.
2193 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2195 Use execve to avoid need to munge environ (Bug#13054).
2196 * callproc.c (Fcall_process):
2197 * process.c (create_process):
2198 Don't save and restore environ; no longer needed.
2199 * callproc.c (child_setup):
2200 Use execve, not execvp, to preserve environ.
2202 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2204 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2206 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2208 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2209 display for sliced images (Bug#10500).
2211 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2213 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2215 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2216 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2218 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2220 * xdisp.c (window_outdated): Remove eassert since it hits
2221 some suspicious corner cases (see Bug#13007 and Bug#13012).
2222 (mode_line_update_needed): New function.
2223 (redisplay_internal, redisplay_window): Use it.
2224 (ensure_selected_frame): New function.
2225 (redisplay_internal, unwind_redisplay): Use it.
2226 (redisplay_internal): Move comment about buffer_shared...
2227 (buffer_shared_and_changed): ...near to its real use.
2229 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2231 * callproc.c (Fcall_process): Don't misreport vfork failure.
2233 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2235 * callproc.c (Fcall_process): Fix vfork portability problems.
2236 Do not assume that fd[0], count, filefd, and save_environ survive
2237 vfork. Fix bug whereby wrong errno value could be reported for
2238 pipe failure. Some minor cleanups, too, as follows. Move buf and
2239 bufsize to the context where they're needed. Change new_argv to
2240 be of type char **, as this is more convenient and avoids casts.
2241 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2242 Now local constants, not macros.
2244 2012-11-18 Kenichi Handa <handa@gnu.org>
2246 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2247 for the variable "f".
2249 2012-11-13 Kenichi Handa <handa@gnu.org>
2251 * font.c (font_unparse_xlfd): Exclude special characters from the
2252 generating XLFD name.
2254 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2256 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

2258 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2260 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2267 * lread.c (readbyte_from_file): Assume EINTR is defined.
2268 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2269 Assume EIO and EAGAIN are defined.
2270 * unexcoff.c (write_segment): Assume EFAULT is defined.
2272 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2274 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2277 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2278 highlighting on the frame was cleared. Prevents assertion
2279 violations when repeatedly clicking on the "Top" link of the
2280 "bread-crumbs" in Info buffers.
2282 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2284 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2286 2012-11-24 Ken Brown <kbrown@cornell.edu>
2288 * keyboard.c (HAVE_MOUSE):
2289 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2290 were always defined.
2292 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2294 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2295 between bpos_covered and bpos_max. This fixes cursor display when
2296 several display strings follow each other.
2298 * .gdbinit (pgx): If the glyph's object is a string, display the
2299 pointer to string data, rather than the value of the string object
2300 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2302 * indent.c (Fvertical_motion): If the starting position is covered
2303 by a display string, return to one position before that, to avoid
2304 overshooting it inside move_it_to. (Bug#12930)
2306 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2308 * frame.h (struct frame): Remove display_preempted member
2309 since all users are dead long ago.

2311 * w32menu.c (pending_menu_activation): Remove since not
2313 (set_frame_menubar): Adjust user.
2314 * w32term.h (struct x_output): Drop outdated #if 0 code.
2315 (struct w32_output): Use bitfields for explicit_parent,
2316 asked_for_visible and menubar_active members.
2317 Drop unused pending_menu_activation member.
2318 * xterm.h (struct x_output): Drop outdated #if 0 code.
2319 Use bitfields for explicit_parent, asked_for_visible,
2320 has_been_visible and net_wm_state_hidden_seen members.
2322 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2324 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2325 of a literal "/". (Bug#12955)
2326 (gl-stamp): Invoke fc.exe directly, not through cmd.
2328 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2330 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2331 * dired.c: Assume HAVE_DIRENT_H.
2332 (NAMLEN): Remove, replacing with ...
2333 (dirent_namelen): New function. All uses changed. Use the GNU macro
2334 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2335 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2336 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2337 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2339 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2340 * ndir.h: Rename to ../nt/inc/dirent.h.
2341 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2342 Do not include <dirent.h>; no longer needed.
2343 * w32.c: Include <dirent.h> rather than "ndir.h".
2345 2012-11-23 Chong Yidong <cyd@gnu.org>
2347 * xftfont.c (xftfont_open): Remove duplicate assignment.
2349 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2351 * alloc.c (Fgarbage_collect): Unblock input after clearing
2352 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2353 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2354 * msdos.c (IT_frame_up_to_date): Use it here...
2355 * w32term.c (w32_frame_up_to_date): ...here...
2356 * xterm.c (XTframe_up_to_date): ...and here...
2357 * nsterm.m (ns_frame_up_to_date): ...but not here.
2358 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2360 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2361 Do not check whether GC is in progress.
2363 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2365 * xdisp.c (window_buffer_changed): New function.
2366 (update_menu_bar, update_tool_bar): Use it to
2367 simplify large 'if' statements.
2368 (redisplay_internal): Generalize commonly used
2369 'tail' and 'frame' local variables.
2371 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2373 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2374 with Windows system header.
2376 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2378 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2379 * alloc.c: Assume unistd.h exists.
2380 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2381 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2382 (getwd) [USG]: Remove; no longer needed.
2383 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2384 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2385 * w32.h (getcwd): Remove decl.
2387 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2389 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2390 Make it set selected_window as well.
2391 (update_tool_bar): Use it.
2393 2012-11-21 Ken Brown <kbrown@cornell.edu>
2395 * emacs.c (main): Set the G_SLICE environment variable for all
2396 Cygwin builds, not just GTK builds. See
2397 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2399 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2401 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2402 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2403 Define for the MSVC compiler.
2405 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2407 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2408 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2409 dostounix_filename. Prevents crashes down the road, because
2410 dostounix_filename assumes it gets a unibyte string.
2411 Reported by Michel de Ruiter <michel@sentient.nl>, see
2412 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2414 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2416 Conflate Qnil and Qunbound for `symbol-function'.

2418 * lread.c (init_obarray): Set `function' fields to Qnil.
2419 * eval.c (Fcommandp): Ignore Qunbound.
2420 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2421 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2422 Test NILP rather than Qunbound.
2423 (Ffmakunbound): Set to Qnil.
2424 (Fsymbol_function): Never signal an error.
2425 (Finteractive_form): Ignore Qunbound.
2427 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2429 * eval.c (interactive_p): Remove no-longer-used decl.
2431 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2433 * xdisp.c (buffer_shared): Adjust comment.
2434 (buffer_shared_and_changed): New function.
2435 (prepare_menu_bars, redisplay_internal): Use it to
2436 decide whether all windows or frames should be updated.
2437 (window_outdated): New function.
2438 (text_outside_line_unchanged_p, redisplay_window): Use it.
2439 (redisplay_internal): Likewise. Fix indentation.
2441 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2443 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2444 (syms_of_eval): Remove corresponding defsubr.
2445 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2447 2012-11-19 Daniel Colascione <dancol@dancol.org>
2449 * w32fns.c (Fx_file_dialog):
2450 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2451 cygwin_convert_file_name*.
2453 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2454 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2456 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2458 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2460 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2462 * w32select.c: Include w32common.h before w32term.h, so that
2463 windows.h gets included before w32term.h uses some of its
2464 features, see below.
2466 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2468 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2470 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2472 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2474 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2475 (ns_select): Return at once if events are held (Bug#12834).
2477 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2479 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2480 Needed following 2012-10-20 change. (Bug#12902)
2482 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2484 * w32proc.c (waitpid): Remove unused label get_result.
2486 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2488 * makefile.w32-in (SYSWAIT_H): New macro.
2489 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2490 ($(BLD)/sysdep.$(O)): Update dependencies.
2492 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2494 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2495 * callproc.c (relocate_fd): Assume F_DUPFD.
2496 * emacs.c, term.c (O_RDWR): Remove.
2497 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2498 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2499 * nsterm.m: Assume <fcntl.h> exists.
2500 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2501 (create_pty, Fmake_network_process, server_accept_connection)
2502 (wait_reading_process_output, init_process_emacs):
2504 (wait_reading_process_output): Put in a special case for WINDOWSNT
2505 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2506 It's not clear this is needed, but it's a more-conservative change.
2507 (create_process): Assume FD_CLOEXEC.
2508 (create_process, create_pty): Assume O_NOCTTY.
2509 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2510 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2511 Omit if not DOS_NT, since F_GETFL is not defined there.
2512 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2513 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2515 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2516 lack it, since gnulib guarantees this.
2517 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2519 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2521 * w32.c (faccessat): Pretend that directories have the execute bit
2522 set. Emacs expects that, e.g., in files.el:cd-absolute.
2524 * w32proc.c (create_child): Don't clip the PID of the child
2525 process to fit into an Emacs integer, as this is no longer a
2527 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2528 reaping only the process specified by PID argument, if that is
2529 positive. Use PID instead of dead_child to know which process to
2530 reap. Wait for the child to die only if WNOHANG is not in
2532 (sys_select): Don't set dead_child.
2534 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2535 as it is no longer needed.
2537 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2539 (record_child_status_change): Remove the setting of
2540 record_at_most_one_child for the !WNOHANG case.
2542 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2544 Fix problems in ns port found by static checking.
2545 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2546 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2547 not to process group.
2548 (ns_select): Use emacs_write, not write, as that's more robust
2549 in the presence of signals.
2550 (fd_handler:): Check for read errors.
2552 2012-11-16 Glenn Morris <rgm@gnu.org>
2554 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2556 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2558 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2560 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2562 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2563 use the same value of thread handle.
2564 (start_timer_thread): If the timer thread exited (due to error),
2565 clean up by closing the two handles it used. Duplicate the caller
2566 thread's handle here, so it gets duplicated only once, when
2567 launching the timer thread. Set priority of the timer thread, not
2569 (getitimer): Don't duplicate the caller thread's handle here.
2572 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2574 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2577 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2579 Remove no-longer-used pty_max_bytes variable.
2580 * process.c (pty_max_bytes): Remove; unused.
2581 (send_process): Do not set it.
2583 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2585 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2586 Update dependencies.
2588 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2590 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2591 This follows up on the 2012-09-29 patch that removed indirection
2592 for the 'function' field. Reported by Sergey Vinokurov in
2593 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2595 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2597 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2598 different name, as the MS runtime does not have such a function,
2599 and probably never will.) All callers changed. Ignore DIRFD
2600 value if PATH is an absolute file name, to match Posix spec
2601 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2604 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2606 * xdisp.c (echo_area_display, redisplay_internal):
2607 Omit redundant check whether frame_garbaged is set.
2609 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2611 Use faccessat, not access, when checking file permissions (Bug#12632).
2612 This fixes a bug that has been present in Emacs since its creation.
2613 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2614 which must set some sort of record. (Torek's bug report was against
2615 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2616 same common flaw.) See Torek's Usenet posting
2617 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2618 Posted: Fri Apr 8 14:18:56 1983.
2619 * Makefile.in (LIB_EACCESS): New macro.
2621 * callproc.c (init_callproc):
2622 * charset.c (init_charset):
2623 * fileio.c (check_existing, check_executable, check_writable)
2625 * lread.c (openp, load_path_check):
2626 * process.c (allocate_pty):
2628 Use effective UID when checking permissions, not real UID.
2629 * callproc.c (init_callproc):
2630 * charset.c (init_charset):
2631 * lread.c (load_path_check, init_lread):
2632 Test whether directories are accessible, not merely whether they exist.
2633 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2634 * fileio.c (check_existing, check_executable, check_writable)
2636 Use symbolic names instead of integers for the flags, as they're
2638 (check_writable): New arg AMODE. All uses changed.
2639 Set errno on failure.
2640 (Ffile_readable_p): Use faccessat, not stat + open + close.
2641 (Ffile_writable_p): No need to call check_existing + check_writable.
2642 Just call check_writable and then look at errno. This saves a syscall.
2643 dir should never be nil; replace an unnecessary runtime check
2644 with an eassert. When checking the parent directory of a nonexistent
2645 file, check that the directory is searchable as well as writable, as
2646 we can't create files in unsearchable directories.
2647 (file_directory_p): New function, which uses 'stat' on most platforms
2648 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2649 (Ffile_directory_p, Fset_file_times): Use it.
2650 (file_accessible_directory_p): New function, which uses a single
2651 syscall for efficiency.
2652 (Ffile_accessible_directory_p): Use it.
2653 * xrdb.c (file_p): Use file_directory_p.
2654 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2655 * lread.c (openp): When opening a file, use fstat rather than
2656 stat, as that avoids a permissions race. When not opening a file,
2657 use file_directory_p rather than stat.
2658 (dir_warning): First arg is now a usage string, not a format.
2659 Use errno. All uses changed.
2660 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2661 that merely introduced a race.
2662 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2663 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2664 and similarly for the other O_* flags.
2665 * w32.c (sys_faccessat): Rename from sys_access and switch to
2666 faccessat's API. All uses changed.
2667 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2668 (magic_db): Rename from magic_file_p.
2669 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2670 char *, so that we don't have to test for file existence
2671 separately from opening the file for reading. This removes a race
2672 fixes a permission-checking problem, and simplifies the code.
2674 (file_p): Remove; no longer needed.
2676 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2678 Omit glyphs initialization at startup.
2679 * dispnew.c (glyphs_initialized_initially_p): Remove.
2680 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2681 (Fredraw_frame): Move actual code from here...
2682 (redraw_frame): ...to here. Add eassert. Adjust comment.
2683 (Fredraw_display): Use redraw_frame.
2684 * xdisp.c (clear_garbaged_frames): Likewise.
2686 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2688 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2689 passed to pint2str and pint2hrstr to be at most the size of the
2690 frame's decode_mode_spec_buffer. This avoids crashes with very
2691 large values of FIELD_WIDTH argument to decode_mode_spec.
2694 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2696 Fix a race with verify-visited-file-modtime (Bug#12863).
2697 Since at least 1991 Emacs has ignored an mtime difference of no
2698 more than one second, but my guess is that this was to work around
2699 file system bugs that were fixed long ago. Since the race is
2700 causing problems now, let's remove that code.
2701 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2702 whose time stamp is off by no more than a second. Insist that the
2703 file time stamps match exactly.
2705 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2707 * frame.h (struct frame): Convert external_tool_bar member to
2708 1-bit unsigned bitfield.
2709 * termhooks.h (struct terminal): Remove mouse_moved member since
2710 all users are long dead. Adjust comment on mouse_position_hook.
2712 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2714 Simplify by using FOR_EACH_FRAME here and there.
2715 * frame.c (next_frame, prev_frame, other_visible_frames)
2716 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2717 * w32term.c (x_window_to_scroll_bar): Likewise.
2718 * window.c (window_list): Likewise.
2719 * xdisp.c (x_consider_frame_title): Likewise.
2720 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2721 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2722 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2723 * xmenu.c (menubar_id_to_frame): Likewise.
2724 * xselect.c (frame_for_x_selection): Likewise.
2725 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2726 (x_window_to_menu_bar): Likewise.
2727 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2729 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2731 * data.c (Qdefalias_fset_function): Now static.
2733 Another tweak to vectorlike_header change.
2734 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2735 Remove, and replace all uses with ...
2736 (next_in_free_list, set_next_in_free_list):
2737 New functions, which respect C's aliasing rules better.
2739 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2741 * window.c (list4i): Rename from 'quad'. All uses changed.
2742 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2744 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2746 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2747 warning about mixing declarations and code in ISO C90.
2749 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2751 * window.c (Fsplit_window_internal): Set combination limit of
2752 new parent window to t iff Vwindow_combination_limit is t;
2753 fixing a regression introduced with the change from 2012-09-22.
2754 (Fset_window_combination_limit): Fix doc-string.
2756 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2758 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2759 amount when the scroll margins are too large. When scrolling
2760 backwards in the buffer, give up if cannot reach point or the
2761 scroll margin within a reasonable number of screen lines.
2762 Fixes point position in window under scroll-up/down-aggressively when
2763 point is positioned many lines beyond the window top/bottom.
2766 * ralloc.c (relinquish): If real_morecore fails to return memory
2767 to the system, don't crash; instead, leave the last heap
2768 unchanged and return. (Bug#12774)
2770 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2772 * lisp.h (AUTOLOADP): New macro.
2773 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2774 * data.c (Ffset): Remove special ad-advice-info handling.
2775 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2777 (Finteractive_form): Simplify.
2778 (Fquo): Don't insist on having at least 2 arguments.
2779 (Qdefalias_fset_function): New var.
2781 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2783 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2785 * nsfont.m (Qcondensed, Qexpanded): New variables.
2786 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2787 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2789 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2791 Fix recently introduced crash on MS-Windows (Bug#12839).
2792 * w32term.h (struct scroll_bar): Use convenient header.
2793 (SCROLL_BAR_VEC_SIZE): Remove.
2794 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2796 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2798 Tweak last vectorlike_header change.
2799 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2800 vectorlike object on the free list. This is introduced to avoid
2801 some (but not all) pointer casting and aliasing problems, see

2835 special hash function containing a comparison that always yields 1.
2837 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2839 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2840 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2841 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2844 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2846 * image.c (xpm_make_color_table_h): Fix compiler error because
2847 make_hash_table changed.
2849 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2851 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2853 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2855 Use ad-hoc comparison function for the profiler's hash-tables.
2856 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2857 (make_log): Use them.
2858 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2859 call Fequal any more.

2868 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2869 (hash_lookup, hash_remove_from_table): Move assertion checking of
2870 hashfn result here. Check hash-equality before calling cmpfn.

2882 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2883 value of w32-scroll-lock-modifier is neither nil nor one of the
2884 known key modifiers. (Bug#12806)
2886 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2888 Shrink struct vectorlike_header to the only size field.
2889 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2891 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2892 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2893 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2894 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2895 information from the vector header. Adjust comment.

2912 (allocate_vector_from_block): Simplify.
2913 (PSEUDOVECTOR_NBYTES): Replace with...

2919 (allocate_buffer): Use BUFFER_PVEC_INIT.
2920 (live_vector_p): Adjust to match large vector.
2921 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2922 * buffer.h (struct buffer): Add next member.
2923 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2925 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2933 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2935 * keyboard.c (event_to_kboard): Do not dereference
2936 frame_or_window field of SELECTION_REQUEST_EVENT
2937 and SELECTION_CLEAR_EVENT events (Bug#12814).
2938 * xterm.h (struct selection_input_event): Adjust comment.
2940 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2942 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2943 such as Scroll Lock, if the respective keys are treated as
2944 function keys, not as modifiers. This avoids destroying non-ASCII
2945 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2947 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2949 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2951 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2953 Restore some duplicate definitions (Bug#12814).
2954 This undoes part of the 2012-11-03 changes. Some people build
2955 with plain -g rather than with -g3, and they need the duplicate
2956 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2957 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2958 Define as macros, as well as as enums or as constants.
2960 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2962 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2963 to keypad keys (Bug#12816).
2965 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2967 Minor adjustments of recently-changed frame functions.
2968 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2969 known to be a frame (we're in the FRAMEP branch).
2970 * lisp.h (Qframep): Remove decl. frame.h declares this.
2971 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2972 since they're meant for Lisp fixnum values.
2974 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2976 * window.c (Fwindow_combination_limit): Revert to the only
2977 required argument and adjust docstring as suggested in
2978 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2979 by Martin Rudalics <rudalics@gmx.at>.
2981 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2983 Widely used frame validity and checking functions.
2984 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2985 * frame.c (decode_live_frame, decode_any_frame): New functions.
2986 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2987 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2988 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2995 (frame_buffer_list, frame_buffer_predicate): Remove.
2996 * lisp.h (frame_buffer_predicate): Remove prototype.
2997 * buffer.c (Fother_buffer): Use decode_any_frame.
2998 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2999 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3000 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3001 (Fclose_font, Ffont_info): Use decode_live_frame.
3002 * fontset.c (check_fontset_name): Likewise.
3003 * terminal.c (Fframe_terminal): Likewise.
3004 * w32fns.c (check_x_frame): Likewise.
3005 * window.c (Fminibuffer_window, Fwindow_at)
3006 (Fcurrent_window_configuration): Likewise.
3007 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3008 Likewise. Allow zero number of arguments. Adjust docstring.
3009 * dispnew.c (Fredraw_frame): Likewise.
3010 * xfaces.c (frame_or_selected_frame): Remove.
3011 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3012 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3013 (Fframe_face_alist): Use decode_live_frame.
3014 * xfns.c (check_x_frame): Likewise.
3016 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3018 * window.c (quad): New function.
3019 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3020 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3021 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3022 (Fwindow_line_height): Use it.
3023 (Fwindow_fringes): Use list3.
3024 (Fwindow_scroll_bars): Use list4.
3025 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3026 (Fwindow_combination_limit): Allow zero number of arguments.
3028 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3030 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3032 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3033 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3034 file descriptor 2 for standard error. (Bug#12805)
3036 2012-11-05 Chong Yidong <cyd@gnu.org>
3038 * process.c (wait_reading_process_output): Revert previous change.
3040 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3042 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3043 This removes code that has been obsolete since around 1990.
3044 * callproc.c (Fcall_process):
3046 * process.c (create_process):
3047 * term.c (dissociate_if_controlling_tty):
3048 Assume setsid exists.
3049 * callproc.c (child_setup): Assume setpgid exists and behaves as
3050 per POSIX.1-1988 or later.
3051 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3052 * emacs.c (shut_down_emacs):
3053 * sysdep.c (sys_suspend, init_foreground_group):
3054 Assume getpgrp behaves as per POSIX.1-1998 or later.
3055 * msdos.c (setpgrp): Remove.
3056 (tcgetpgrp, setpgid, setsid): New functions.
3057 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3058 * term.c (no_controlling_tty): Remove; unused.
3059 * w32proc.c (setpgrp): Remove.
3060 (setsid, tcgetpgrp): New functions.
3062 Simplify by assuming __fpending.
3063 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3064 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3065 Do not assume that __fpending's result fits in int.
3067 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3069 Remove EMACS_OUTQSIZE+sleep hack.
3070 * dispnew.c (update_frame_1): Remove hack for terminals slower
3071 than 2400 bps, which throttled Emacs by having it sleep.
3072 This code hasn't worked since at least 2007, when the multi-tty stuff
3073 was added, and anyway those old terminals are long dead.
3074 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3075 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3077 Fix data-loss with --version (Bug#9574).
3078 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3079 as we can't assume that emacs_strerror is initialized, and strerror
3080 is good enough here.
3081 (main): Invoke atexit earlier, to catch earlier instances of
3082 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3084 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3086 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3087 (keyDown): Remap keypad keys to X11 virtual key codes.
3089 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3091 Fix data-loss with --batch (Bug#9574).
3092 * emacs.c: Include <close-stream.h>.
3093 (close_output_streams): New function.
3094 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3095 and handles errors appropriately.
3096 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3099 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3100 The symptom is a diagnostic "GLib-WARNING **: In call to
3101 g_spawn_sync(), exit status of a child process was requested but
3102 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3103 waitpid(), so exit status can't be returned." The diagnostic
3104 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3105 The real bug is a race condition between Emacs and glib: Emacs
3106 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3107 so that glib can't find it. Work around the bug by invoking
3108 waitpid only on subprocesses that Emacs itself creates.
3109 * process.c (create_process, record_child_status_change):
3110 Don't use special value -1 in pid field, as the caller now must
3111 know the pid rather than having the callee infer it.
3112 The inference was sometimes incorrect anyway, due to another race.
3113 (create_process): Set new 'alive' member if child is created.
3114 (process_status_retrieved): New function.
3115 (record_child_status_change): Use it.
3116 Accept negative 1st argument, which means to wait for the
3117 processes that Emacs already knows about. Move special-case code
3118 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3119 processes that have already been waited for, by testing and
3120 clearing new 'alive' member.
3121 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3122 now does this internally.
3123 (handle_child_signal): Let record_child_status_change do all
3124 the work, since we do not want to reap all exited child processes,
3125 only the child processes that Emacs itself created.
3126 * process.h (Lisp_Process): New boolean member 'alive'.
3128 Omit duplicate definitions no longer needed with gcc -g3.
3129 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3130 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3131 Define only as macros. There's no longer any need to also define
3132 these symbols as enums or as constants, since we now assume
3133 gcc -g3 when debugging.
3135 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3137 * lisp.mk: Adjust comments to the fact that term/internal is now
3138 loaded from loadup.el.
3140 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3141 (msdos_fatal_signal): New function.
3142 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3145 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3146 for GCC versions before 4.
3147 (emacs_raise): Define to call msdos_fatal_signal.
3149 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3150 iterator when starting in the middle of a display or overlay
3153 2012-11-03 Chong Yidong <cyd@gnu.org>
3155 * process.c (wait_reading_process_output): Clean up the last
3158 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3160 * process.c (wait_reading_process_output): Avoid a race condition
3161 with SIGIO delivery (Bug#11536).
3163 2012-11-03 Chong Yidong <cyd@gnu.org>
3165 * buffer.c (cursor_type): Untabify docstring.
3167 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3169 * frame.h (struct frame): Drop can_have_scroll_bars member
3170 which is meaningless for a long time. Adjust comments.
3171 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3172 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3174 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3176 * window.c (decode_next_window_args): Update window arg after
3177 calling decode_live_window and so fix crash reported at
3178 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3179 by Juanma Barranquero <lekktu@gmail.com>.
3180 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3181 * font.c (Ffont_at): Likewise.
3183 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3185 * widget.c (resize_cb): New function.
3186 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3187 (EmacsFrameResize): Check if all is up to date before changing frame
3190 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3192 Implement backtrace output for fatal errors on MS-Windows.
3193 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3194 (BACKTRACE_LIMIT_MAX): New macro.
3195 (w32_backtrace): New function.
3196 (emacs_abort): Use w32_backtrace when the user chooses not to
3197 attach a debugger. Update the text of the abort dialog.
3199 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3201 Window-related stuff cleanup here and there.
3202 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3203 Use decode_any_window.
3204 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3205 * xdisp.c (Fformat_mode_line): Likewise.
3206 * font.c (Ffont_at): Use decode_live_window.
3207 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3208 * window.c (decode_next_window_args): Likewise.
3209 (decode_any_window): Remove static.
3210 * window.h (decode_any_window): Add prototype.
3211 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3212 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3215 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3217 Remove pad from struct input_event.
3218 * termhooks.h (struct input_event): Remove padding field.
3220 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3221 member is never cons for a long time. Adjust comment.
3222 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3223 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3224 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3225 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3227 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3229 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3231 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3233 Fix crash when using Emacs as commit editor for git (Bug#12697).
3234 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3235 and it is configured in conf_post.h.
3236 (Fcall_process): Don't invoke both setsid and setpgid; the former
3237 is enough, if it exists.
3238 * callproc.c (Fcall_process, child_setup):
3239 * process.c (create_process): Use setpgid.
3240 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3242 * dispnew.c (init_display): Initialize the foreground group
3243 if we are running a tty display.
3244 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3245 * lisp.h (init_foreground_group): New decl.
3246 * sysdep.c (inherited_pgroup): New static var.
3247 (init_foreground_group, tcsetpgrp_without_stopping)

3252 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3254 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3256 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3258 * minibuf.c (read_minibuf): Restore current buffer since
3259 choose_minibuf_frame calling Fset_frame_selected_window may
3260 change it (Bug#12766).
3262 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3264 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3266 2012-10-30 Kenichi Handa <handa@gnu.org>
3268 * font.c (Ffont_at): If WINDOW is specified and it is not
3269 displaying the current buffer, signal an error.
3271 2012-10-29 Daniel Colascione <dancol@dancol.org>
3273 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3274 In preparation for fixing bug#12739, move these functions from
3277 * coding.h, coding.c: ... to here, and compile them only when
3278 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3279 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3281 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3283 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3284 (timer_loop, getitimer, setitimer): Use it instead of

3287 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3290 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

3295 (ns_select): Initialize t from last_appdefined_event_data instead
3296 of [last_appdefined_event data1].
3297 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3298 remove last_appdefined_event (Bug#12698).
3300 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3302 * frame.c (x_set_font): Catch internal error.
3304 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3306 Avoid overflow in w32 implementation of interval timers.
3307 When possible, for ITIMER_PROF count only times the main thread
3309 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3310 'volatile ULONGLONG' types. All the other data which was
3311 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3312 (GetThreadTimes_Proc): New typedef.
3313 (w32_get_timer_time): New function, returns a suitable time value
3315 (timer_loop): Enter critical section when accessing ULONGLONG
3316 values of the itimer_data struct, as these accesses are no longer
3317 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3318 Remove unused variable.
3319 (init_timers): Initialize s_pfn_Get_Thread_Times.
3320 (start_timer_thread): Don't assign itimer->caller_thread here.
3321 (getitimer): Assign itimer->caller_thread here.
3322 (setitimer): Always call getitimer to get the value of ticks_now.
3323 (sys_spawnve): Avoid compiler warning about format mismatch.

3327 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3328 mouse movement events if the menu bar is active. This avoids
3329 producing a busy "hour-glass" cursor by Windows if the mouse
3330 pointer is positioned over a tooltip shown for some menu item.
3332 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3334 Don't assume process IDs fit in int.
3335 * emacs.c (shut_down_emacs) [!DOS_NT]:
3336 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3337 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3338 Use pid_t, not int, to store process IDs, as 'int'
3339 is not wide enough on a few platforms (e.g., AIX and IRIX).
3341 2012-10-23 Kenichi Handa <handa@gnu.org>
3343 The following change is to make face-font-rescale-alist work
3344 correctly for non-ASCII fonts.
3346 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3347 (font_open_for_lface): Handle Vface_font_rescale_alist.

3362 2012-10-21 Glenn Morris <rgm@gnu.org>
3364 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3366 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

3369 * frame.c (Fmouse_position, Fmouse_pixel_position):
3370 * xdisp.c (produce_stretch_glyph):
3371 Declare local vars only when they're needed.
3372 This is clearer and avoids a warning on OpenBSD about unused vars.

3374 This is safer, and avoids OpenBSD warnings about unused vars.
3375 * keyboard.c (record_menu_key): Remove unnecessary decl.
3376 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3377 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3378 as our definition clashes with OpenBSD's.
3379 * xfaces.c (load_face_colors, check_lface_attrs)
3380 (get_lface_attributes_no_remap, get_lface_attributes)
3381 (lface_fully_specified_p, x_supports_face_attributes_p)
3382 (tty_supports_face_attributes_p, face_fontset, realize_face)
3383 (realize_x_face, realize_tty_face):
3384 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3385 merely Lisp_Object *. This is more informative and avoids
3386 a warning on OpenBSD about accessing beyond an object's size.
3388 2012-10-20 Chong Yidong <cyd@gnu.org>
3390 * lread.c (Fload): Doc fix (Bug#12592).

3416 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3417 (staticpro): If we run out of staticpro slots, die with an
3418 informative error instead of just calling emacs_abort.
3420 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3422 Fix two flaws reported by Dmitry Antipov.

3679 (get_input_pending): Remove first argument, since it was always
3680 the same pointer-to-int (now pointer-to-boolean) &input_pending,

3682 input_pending. All callers changed.
3683 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3684 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3724 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3726 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3727 match what GetLastError returns. Explain why the function is
3730 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3731 'is_tooltip_frame', to avoid confusion with its global namesake.
3733 2012-10-08 Daniel Colascione <dancol@dancol.org>
3735 * xdisp.c (start_hourglass): Call w32_note_current_window when
3736 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3737 build that caused Emacs to display the hourglass cursor forever.
3739 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3740 which is broken under remote desktop, calculate the number of
3741 colors available for a display based on the display's number of
3742 planes and number of bits per pixel per plane. (bug#10397).
3744 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3746 * nsfont.m (Vfonts_in_cache): New variable.
3747 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3748 are used. Add cached fonts to Vfonts_in_cache.
3749 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3751 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3753 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3755 (FONT_H): Define after FRAME_H.
3756 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3757 Update dependencies.
3759 * w32term.c: Remove leftover declaration of keyboard_codepage.
3761 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3763 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3764 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3765 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3766 (GLOBAL_SOURCES): Add cygw32.c.
3767 ($(BLD)/unexw32.$(O)):
3769 ($(BLD)/w32console.$(O)):
3770 ($(BLD)/w32fns.$(O)):
3771 ($(BLD)/w32heap.$(O)):
3772 ($(BLD)/w32menu.$(O)):
3773 ($(BLD)/w32proc.$(O)): Add w32common.h.
3775 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3777 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3779 2012-10-08 Daniel Colascione <dancol@dancol.org>
3781 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3782 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3783 accidental message numbering hole. Change other messages to
3786 * w32select.h (HAVE_W32SELECT): Remove.
3788 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3789 w32common.h instead of w32heap.h.
3791 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3792 (get_allocation_unit, get_processor_type, get_w32_major_version)
3793 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3794 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3795 (OS_NT, os_subtype, cache_system_info): Move declarations to
3798 * w32heap.c: Include w32common.h.
3799 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3800 (w32_minor_version, w32_build_number, w32_subtype):
3801 Remove duplicate definitions.
3803 * w32fns.c: Include w32common.h; include w32heap.h only in
3806 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3807 Use `report_file_error' instead of `error' in order to better
3808 inform users of what went wrong. Increase NTGUI_UNICODE file
3809 dialog box file name length to 32k, the maximum allowed by the NT
3812 * w32common.h: New file.
3813 (ROUND_UP, ROUND_DOWN, get_page_size)
3814 (get_allocation_unit, get_processor_type, get_w32_major_version)
3815 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3816 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3817 (OS_NT, os_subtype, cache_system_info): Move here.
3819 * unexw32.c, unexcw.c: Include w32common.h.
3821 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3822 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3823 to call syms_of_w32select.
3825 * cygw32.h: Remove obsolete EXFUN declarations.
3827 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3829 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3830 of w32inevt.o from SOME_MACHINE_OBJECTS.
3832 2012-10-08 Daniel Colascione <dancol@dancol.org>
3834 * image.c: Permanent fix for JPEG compilation issue --- limit
3835 jpeglib `boolean' redefinition to Cygwin builds.
3837 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3839 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3841 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3844 2012-10-08 Daniel Colascione <dancol@dancol.org>
3846 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3847 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3848 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3849 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3850 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3851 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3852 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3853 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3854 now a supported configuration.
3856 * Makefile.in: consolidate image variables into LIBIMAGE; add
3857 W32_OBJ and W32_LIBS. Compile new files.
3860 (_DebPrint) declare tracing facility for W32 debugging. We need
3861 to unify tracing later.
3863 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3864 unconditional use of W32 Unicode functions. Cygwin runs only on
3865 100% Unicode operating systems.
3867 * cygw32.c: New file. Define Cygwin-specific facilities.
3868 (Fcygwin_convert_path_to_windows)
3869 (Fcygwin_convert_path_from_windows): New user functions for
3870 accessing Cygwin path-munging routines.
3872 * cygw32.h: New file.
3873 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3874 UTF-16LE strings temporarily inside non-Lisp-visible string
3877 (w32_strerror): Just what it says on the tin.
3879 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3880 also run for Cygwin; both systems have the same problem with using
3881 GUI facilities in a forked child. Also call syms_of_cygw32,
3882 syms_of_w32select in correct places.
3884 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3885 needs fork-then-exec for daemon launching.
3887 * font.h: Include frame.h.
3889 * image.c: Use the image library cache machinery only when we're
3890 compiling for native WINDOWSNT; Cygwin can use shared libraries
3891 like any other Unixlike system.
3893 * keyboard.c: Clarify a comment regarding the input loop.
3895 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3896 functions directly instead of trying to detect at runtime that our
3897 host operating system supports them. We make this change for two
3898 reasons: Cygwin lacks support for the multibyte character
3899 conversion functions used by the legacy menu code, and Cygwin
3900 never needs to rely on non-Unicode APIs.
3902 * unexw32.c (hinst): Declare extern.
3904 * w32.c: Change header order;
3905 (w32_strerror): Move to w32fns.c because we need it for
3906 non-WINDOWSNT builds.
3908 * w32.h: Add #error macro to make sure we don't include w32.h for
3909 Cygwin builds. Remove w32select declarations.
3911 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3912 w32fns.c. w32console.c is WINDOWSNT-only.
3914 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3915 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3917 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3918 (w32_major_version, w32_minor_version, w32_build_number)
3919 (os_subtype, sound_type): Define here
3920 (w32_defined_color): Make color parameter const for consistency
3921 with other _defined_color functions.
3922 (w32_createwindow): Unconditionally call w32_init_class instead of
3923 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3924 through the code is complex and unnecessary because class
3925 registration is practically free.
3926 (w32_name_of_message): New EMACSDEBUG-only function.
3927 (Fset_message_beep): Move here
3928 (Fx_open_connection): Require that the display name for Windows be
3929 "w32" for consistency, emacsclient disambiguation, and maybe, one
3930 day, multi-window-system support.
3931 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3932 Cygwin files for W32 GUI facilities, since these clearly don't
3933 expect Cygwin names.
3934 (_DebPrint): Define.
3935 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3936 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3937 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3938 (w32_last_error): Remove.
3940 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3942 * w32heap.c (syspage_mask): Declare here.
3943 (cache_system_info): Remove.
3945 * w32inevt.c (faked_key): Define globally, not statically.
3946 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3947 (w32_console_toggle_lock_key): Move to w32fns.c.
3949 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3951 * w32proc.c (_DebPrint): Move to w32fns.c.
3952 * w32select.c: Include string.h, stdio.h for Cygwin.
3953 * w32select.h: New File.
3955 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3957 (w32_message_fd): New variable. Under Cygwin, holds the file
3958 descriptor the system used to tell us about pending thread
3961 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3962 that prevented compilation under non-WINDOWSNT systems.
3964 (w32_initialize): Open /dev/windows and assign it to
3965 w32_message_fd. Provide w32 feature.
3967 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3968 (WM_EMACS_INPUT_READY): add.
3969 (prepend_msg, w32_message_fd): Declare globally.
3972 (keyboard_handle): Use only when WINDOWSNT.
3973 (notify_msg_ready): New function. Posts a message to the main
3974 thread's message queue under CYGWIN, which wakes up the main
3975 thread from select(2) by making the /dev/windows file descriptor
3976 ready. Under WINDOWSNT, it sets an event the same way the old
3979 (post, prepend_msg): Actually call notify_msg_ready instead of
3980 setting the input event directly.
3982 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3984 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3985 but it still has blocs in it, don't return it to the system,
3986 instead of aborting. (Bug#12402)
3988 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3990 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3992 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3993 MAC_OS_X_VERSION_10_6.
3994 (syms_of_nsterm): Remove comment about Panther and above for
3996 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3997 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3998 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4000 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4001 MAC_OS_X_VERSION_10_4.
4003 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4004 MAC_OS_X_VERSION_10_2.
4006 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4008 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4009 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4011 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4012 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4013 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4014 Remove ns_in_resize check.
4015 (ns_clear_frame_area): Remove resize handle code.
4017 * nsfns.m (ns_in_resize): Remove.
4018 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4019 Remove ns_in_resize check.
4021 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4023 Improve sys_siglist detection.
4024 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4025 defined as a macro, as is done in Solaris.
4026 (sys_siglist_entries): New macro.
4027 (save_strsignal): Use it.
4028 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4029 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4031 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4033 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4034 fullscreen/Fullscreen.
4036 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4037 tobar_height is new.
4039 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4040 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4041 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4042 (windowDidResize:): Check for correct window if old style fullscreen.
4043 Capitalize word in comment. Remove incorrect comment.
4044 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4045 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4046 error in drawing background.
4047 (toggleFullScreen:): Remove comment. Rearrange calls.
4048 Set toolbar values to zero, save old height in tobar_height.
4049 Restore tool bar height when leaving fullscreen.
4050 (canBecomeMainWindow): New function.
4052 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4054 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4056 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4058 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4060 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4061 that time stamps of directories could also be changed.
4062 Don't request the too broad GENERIC_WRITE, only the more restrictive
4063 FILE_WRITE_ATTRIBUTES access rights.
4065 * fileio.c (Fset_file_times): Special-case ignoring errors for
4066 directories only on MSDOS, not on MS-Windows.
4068 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4070 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4072 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4074 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4075 see whether CreateFile failed.
4077 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4079 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4080 to avoid similar races.
4081 * keyboard.c (pending_signals): Now bool, not int.
4083 Port timers to OpenBSD, plus check for timer failures.
4084 OpenBSD problem reported by Han Boetes.
4085 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4087 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4088 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4089 like OpenBSD, which has timer_settime but does not declare it.
4090 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4091 whether to use itimerspec-related primitives. All uses of
4092 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4094 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4096 * profiler.c (handle_profiler_signal): Fix a malloc race
4097 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4099 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4101 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4103 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4105 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4106 consistent with the change in return value of 'safe_strsignal'.
4108 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4110 Prefer plain 'static' to 'static inline' (Bug#12541).
4111 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4112 (bidi_set_sor_type, bidi_push_embedding_level)
4113 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4114 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4115 (bidi_cache_search, bidi_cache_ensure_space)
4116 (bidi_cache_iterator_state, bidi_cache_find)
4117 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4118 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4119 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4120 Now 'static', not 'static inline'.
4122 Count overruns when profiling; change units to ns.
4123 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4124 Give extra weight to samples after overruns, to attempt to count
4125 the time more accurately.
4126 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4127 the underlying primitives nominally do ns.
4128 (Fprofiler_cpu_start): Document the change. Mention that
4129 the sampling intervals are only approximate.
4131 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4133 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4135 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4136 case for the special 0 coding-system.
4138 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4139 (Fmake_overlay): Remove redundant tests.
4140 (fix_start_end_in_overlays): Remove redundant recentering.
4142 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4144 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4145 Update dependencies.
4147 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4149 Fix a malloc race condition involving strsignal.
4150 A signal can arrive in the middle of a malloc, and Emacs's signal
4151 handler can invoke strsignal, which can invoke malloc, which is
4152 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4153 Fix it by altering the signal handler so that it does not invoke
4155 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4156 * process.c (status_message): Use const pointer, in case strsignal
4157 is #defined to safe_strsignal.
4158 * sysdep.c (sys_siglist, init_signals): Always define and
4159 initialize a substitute sys_siglist if the system does not define
4160 one, even if HAVE_STRSIGNAL.
4161 (safe_strsignal): Rename from strsignal. Always define,
4162 using sys_siglist. Return a const pointer.
4163 * syssignal.h (safe_strsignal): New decl.
4164 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4166 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4168 * w32proc.c (timer_loop): Fix code that waits for timer
4169 expiration, to avoid high CPU usage.
4171 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4173 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4174 (sweep_weak_table): Remove redundant prototypes.
4176 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4178 * emacs.c: Move the inclusion of TERM_HEADER after including
4179 windows.h on WINDOWSNT. This avoids compilation problems with
4182 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4184 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4185 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4186 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4187 as the previous version used 'void *'.
4189 * ralloc.c (ROUNDUP): Fix last change.
4190 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4193 * w32proc.c <disable_itimers>: New static flag.
4194 (init_timers): Initialize it to zero, after creating the critical
4195 sections used by the timer threads.
4196 (term_timers): Set to 1 before deleting the critical sections.
4197 (getitimer, setitimer): If disable_itimers is non-zero, return an
4198 error indication without doing anything. Reported by Fabrice
4199 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4200 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4202 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4205 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4206 term_ntproc after all the other bookkeeping, to get timers working
4207 as long as possible.
4209 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4211 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4212 Suggested by Juri Linkov in
4213 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4215 Prefer plain 'static' to 'static inline' (Bug#12541).
4216 With static functions, modern compilers inline pretty well by
4217 themselves; advice from programmers often hurts as much as it helps.
4218 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4219 this change shrinks the text size of the Emacs executable by 1.1%
4220 without affecting CPU significantly in my benchmark.

4301 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4303 Revert the FOLLOW-SYMLINKS change for file-attributes.
4304 Doing it right would require several changes to Tramp, and there's
4305 not enough time to get that tested before the freeze today.
4306 * dired.c (directory_files_internal, Ffile_attributes):
4309 * frame.c (x_report_frame_params): Port better to wider ints.
4310 Do not assume that EMACS_UINT is the same width as uprintmax_t,

4513 All uses changed to store the new value.
4514 (handle_profiler_signal): Rename from sigprof_handler_1,
4515 for consistency with other handlers. Do not check whether
4516 cpu_log is a hash-table if garbage collecting, since it
4517 doesn't matter in that case.

4519 for consistency with other handlers.
4520 (setup_cpu_timer): New function, with much of what used to be in
4521 Fprofiler_cpu_start. Check for out-of-range argument.
4522 Prefer timer_settime if available, and prefer
4523 thread cputime clocks, then process cputime clocks, then
4524 monotonic clocks, to the old realtime clock. Use make_timeval
4525 to round more-correctly when falling back to setitimer.
4526 (Fprofiler_cpu_start): Use it.
4527 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4528 Don't assume that passing NULL as the 2nd argument of setitimer
4529 is the same as passing a pointer to all-zero storage.
4530 Ignore SIGPROF afterwards.
4531 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4532 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4533 non-fatal signal handlers. Ignore SIGPROF on startup.
4534 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4535 in profiler.c, since sysdep.c now uses it.
4537 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4593 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4594 Since this stuff is now private to charset.c, there's no need for
4595 a public macro and no need to inline by hand.

4628 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4630 Prefer POSIX timers if available.
4631 They avoid a race if the timer is too close to the current time.
4632 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4633 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4634 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4636 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4638 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
4639 CHAR_STRING_ADVANCE.
4640 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4641 STRING_CHAR_ADVANCE.
4643 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4645 Move Vlibrary_cache to emacs.c and reset before dumping.
4647 * lisp.h (reset_image_types): Declare.
4648 [WINDOWSNT] (Vlibrary_cache): Declare.
4650 * image.c (reset_image_types): New function.
4652 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
4653 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
4654 (Fdump_emacs): Reset Vlibrary_cache and image_types.
4656 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
4657 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
4659 * w32.h (Vlibrary_cache): Do not declare.
4661 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4663 * w32proc.c (sys_signal): Handle all signals defined by the
4664 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4665 handlers for signals supported by Windows. Don't override
4666 term_ntproc as the handler for SIGABRT.
4667 (sigaction): Rewrite to call sys_signal instead of duplicating its
4669 (sys_kill): Improve commentary.
4671 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4672 consistency with a signature of a signal handler. All callers
4674 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4675 install term_ntproc as a signal handler for SIGABRT, as that
4676 should be done by the dumped Emacs.
4678 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4680 * w32select.c (term_w32select): Protect against repeated
4681 invocation by setting clipboard_owner to NULL after calling
4684 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4685 and term_ntproc to their modified signatures.
4687 * character.c (char_string, string_char): Remove calls to
4688 MAYBE_UNIFY_CHAR. See the discussion starting at
4689 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4692 2012-09-25 Chong Yidong <cyd@gnu.org>
4694 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4696 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4698 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4699 when encountering an unknown bytecode.
4701 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4703 image.c, indent.c: Use bool for booleans.
4704 * dispextern.h (struct image_type): Members valid_p, load, init
4705 now return bool, not int. All uses changed.
4706 * image.c: Omit unnecessary static decls.
4707 (x_create_bitmap_mask, x_build_heuristic_mask):
4708 Return void, not int, since callers don't care about the return value.
4709 (x_create_bitmap_mask, define_image_type, valid_image_p)

4737 Use bool for booleans.
4739 2012-09-24 Chong Yidong <cyd@gnu.org>
4741 * chartab.c (Fset_char_table_default): Obsolete function removed.
4743 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4745 Move pid_t related decls out of lisp.h.
4746 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4747 (interruptible_wait_for_termination):
4748 Move these decls from lisp.h to syswait.h, since they use pid_t.
4749 Needed on FreeBSD; see Herbert J. Skuhra in
4750 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4751 * callproc.c: Include syswait.h.
4753 gnutls.c, gtkutil.c: Use bool for boolean.
4754 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)

4766 (update_frame_tool_bar, free_frame_tool_bar):
4767 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
4768 * nsmenu.m (ns_update_menubar):
4769 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4770 * xfns.c (Fx_show_tip) [USE_GTK]:
4771 Use bool for boolean.
4772 * gtkutil.c (xg_update_frame_menubar):
4773 * xmenu.c (update_frame_menubar):
4774 Return void, not int, since caller ignores return value.
4775 * gtkutil.c (xg_change_toolbar_position):
4778 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4780 * makefile.w32-in (BLOCKINPUT_H): Remove.
4781 (SYSSIGNAL_H): New macro.
4782 ($(BLD)/alloc.$(O), $(BLD)/atimer.$(O), $(BLD)/buffer.$(O))

4797 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4799 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4800 fatal_error_backtrace.
4802 * w32proc.c (sys_kill): Undo last change: don't do anything when
4803 invoked to deliver SIGABRT to our own process. This is now
4804 handled by emacs_raise.
4806 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4808 * w32term.c (w32_read_socket): Remove leftover reference to
4809 interrupt_input_pending.
4811 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4813 Do not use SA_NODEFER.
4814 Problem reported by Dani Moncayo in
4815 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4817 * sysdep.c (emacs_abort): Do not reset signal handler.
4818 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4819 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4820 wanted even on POSIXish hosts, and it doesn't work on Windows.
4822 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4824 * xterm.c (x_term_init): Call fixup_locale before and after calling
4825 gtk_init (Bug#12392).
4827 2012-09-23 Chong Yidong <cyd@gnu.org>
4829 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4830 Vdynamic_library_alist.
4832 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4833 (Fgnutls_available_p): Caller changed.
4835 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4836 (Flibxml_parse_xml_region): Likewise.
4838 * dispextern.h (struct image_type): Remove arg from init function.
4840 * image.c (Finit_image_library, lookup_image_type)
4841 (define_image_type): Remove now-unneeded second arg.
4842 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4843 (init_tiff_functions, init_gif_functions, init_svg_functions):
4844 Arglist and w32_delayed_load calling convention changed.
4845 (gs_type): Remove init_gs_functions; there is no such function.
4846 (valid_image_p, make_image): Fix caller to lookup_image_type.
4848 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4850 Simplify and avoid signal-handling races (Bug#12471).
4852 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4853 Avoid recursive loop if there's a fatal error in the function itself.
4854 * atimer.c (pending_atimers):
4855 * blockinput.h: Don't include "atimer.h"; no longer needed.
4856 (interrupt_input_pending): Remove. All uses removed.
4857 pending_signals now counts both atimers and ordinary interrupts.
4858 This is less racy than having three separate pending-signal flags.
4859 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4861 Rename from their upper-case counterparts BLOCK_INPUT,
4862 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4863 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4864 This makes it easier to access volatile variables more accurately.
4865 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4866 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4867 that's more reliable if the code is buggy and sets
4868 interrupt_input_blocked to a negative value. All uses changed.
4869 * atimer.c (deliver_alarm_signal):
4870 Remove. No need to deliver this to the parent; any thread can
4871 handle this signal now. All uses replaced by underlying handler.
4872 * atimer.c (turn_on_atimers):
4873 * dispnew.c (handle_window_change_signal):
4874 * emacs.c (handle_danger_signal):
4875 * keyboard.c (kbd_buffer_get_event):
4876 Don't reestablish signal handler; not needed with sigaction.
4877 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4879 Rework to avoid unnecessary accesses to volatile variables.
4880 (UNBLOCK_INPUT_TO): Now a function.
4881 (totally_unblock_input, unblock_input): New decls.
4882 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4883 (init_data): Remove. Necessary stuff now done in init_signal.
4884 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4885 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4886 (fatal_error_code): Remove; no longer needed.
4887 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4888 it doesn't always backtrace. All uses changed. No need to reset
4889 signal to default, since sigaction and/or die does that for us now.
4890 Use emacs_raise (FOO), not kill (getpid (), FOO).
4891 (main): Check more-accurately whether we're dumping.
4892 Move fatal-error setup to sysdep.c
4893 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4894 * gtkutil.c (xg_get_file_name, xg_get_font):
4895 Remove no-longer-needed signal-mask manipulation.
4896 * keyboard.c, process.c (POLL_FOR_INPUT):
4897 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4898 * keyboard.c (read_avail_input): Remove.
4899 All uses replaced by gobble_input.
4900 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4901 (kbd_buffer_store_event_hold, gobble_input):
4902 (record_asynch_buffer_change) [USABLE_SIGIO]:
4903 (store_user_signal_events):
4904 No need to mess with signal mask.
4905 (gobble_input): If blocking input and there are terminals, simply
4906 set pending_signals to 1 and return. All hooks changed to not
4907 worry about whether input is blocked.
4908 (process_pending_signals): Clear pending_signals before processing
4909 them, in case a signal comes in while we're processing.
4910 By convention callers now test pending_signals before calling us.
4911 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4912 New functions, to support changes to blockinput.h.
4913 (handle_input_available_signal): Now extern.
4914 (reinvoke_input_signal): Remove. All uses replaced by
4916 (quit_count): Now volatile, since a signal handler uses it.
4917 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4918 All callers changed. Block SIGINT only if not already blocked.
4919 Clear sigmask reliably, even if Fsignal returns, which it can.
4920 Omit unnecessary accesses to volatile var.
4921 (quit_throw_to_read_char): No need to restore sigmask.
4922 * keyboard.c (gobble_input, handle_user_signal):
4923 * process.c (wait_reading_process_output):
4924 Call signal-handling code rather than killing ourselves.
4925 * lisp.h: Include <float.h>, for...
4926 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4927 (pending_signals): Now volatile.
4928 (syms_of_data): Now const if IEEE floating point.
4929 (handle_input_available_signal) [USABLE_SIGIO]:
4930 (terminate_due_to_signal, record_child_status_change): New decls.
4931 * process.c (create_process): Avoid disaster if memory is exhausted
4932 while we're processing a vfork, by tightening the critical section
4934 (send_process_frame, process_sent_to, handle_pipe_signal)
4935 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4937 (send_process): No need for setjmp/longjmp any more, since the
4938 SIGPIPE stuff is now gone. Instead, report an error if errno
4940 (record_child_status_change): Now extern. PID and W are now args.
4941 Return void, not bool. All callers changed.
4942 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4943 Remove. All uses removed. This bug should be fixed now in a
4945 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4946 and record the child status change directly. This avoids the
4947 need to futz with the signal mask.
4948 (process_fatal_action): Move here from emacs.c.
4949 (emacs_sigaction_flags): New function, containing
4950 much of what used to be in emacs_sigaction_init.
4951 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4952 caught by emacs, to make races less likely.
4953 (deliver_process_signal): Rename from handle_on_main_thread.
4955 (BACKTRACE_LIMIT_MAX): Now at top level.
4956 (thread_backtrace_buffer, threadback_backtrace_pointers):
4958 (deliver_thread_signal, deliver_fatal_thread_signal):
4959 New functions, for more-accurate delivery of thread-specific signals.
4960 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4961 (deliver_arith_signal): Handle in this thread, not
4962 in the main thread, since it's triggered by this thread.
4963 (maybe_fatal_sig): New function.
4964 (init_signals): New arg DUMPING so that we can be more accurate
4965 about whether we're dumping. Caller changed.
4966 Treat thread-specific signals differently from process-general signals.
4967 Block all signals while handling fatal error; that's safer.
4968 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4970 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4971 Ignore SIGPIPE unless batch.
4972 (emacs_backtrace): Output backtrace for the appropriate thread,
4973 which is not necessarily the main thread.
4974 * syssignal.h: Include <stdbool.h>.
4975 (emacs_raise): New macro.
4976 * xterm.c (x_connection_signal): Remove; no longer needed
4977 now that we use sigaction.
4978 (x_connection_closed): No need to mess with sigmask now.
4979 (x_initialize): No need to reset SIGPIPE handler here, since
4980 init_signals does this for us now.
4982 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4984 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4985 background rect may be larger (Bug#12245).
4987 2012-09-23 Chong Yidong <cyd@gnu.org>
4989 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4991 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4993 * .gdbinit: Just stop at fatal_error_backtrace.
4994 See Stefan Monnier's request in
4995 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4996 Remove no-longer-used query of system type.
4998 2012-09-22 Chong Yidong <cyd@gnu.org>
5000 * search.c (Freplace_match): Doc fix (Bug#12325).
5002 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5004 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5005 (Fline_end_position): Doc fix.
5007 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5009 2012-09-22 Chong Yidong <cyd@gnu.org>
5011 * dispextern.h (struct image_type): Add new slot, storing a type
5012 initialization function.
5014 * image.c (define_image_type): Call the image initializer function
5015 if it is defined. Arguments and return value changed.
5016 (valid_image_p, make_image): Callers changed.
5017 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5018 (gif_type, imagemagick_type, svg_type, gs_type):
5019 Add initialization functions.
5020 (Finit_image_library): Call lookup_image_type.
5021 (CHECK_LIB_AVAILABLE): Macro deleted.
5022 (lookup_image_type): Call define_image_type here, rather than via
5023 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5024 (syms_of_image): Move define_image_type calls for xbm_type and
5025 pbm_type to lookup_image_type.
5027 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5029 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5030 'idle_timers' from here ...
5031 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5032 lists, to avoid infloops when the timer does something stupid,
5033 like reinvoke itself with the same or smaller time-out.
5036 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5038 * window.c (Fsplit_window_internal): Handle only Qt value of
5039 Vwindow_combination_limit separately.
5040 (Qtemp_buffer_resize): New symbol.
5041 (Vwindow_combination_limit): New default value.
5044 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5046 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5047 the new overlay string. (Bug#10159)
5049 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5051 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5052 or that fprintf is async-signal-safe. POSIX doesn't require
5055 2012-09-22 Chong Yidong <cyd@gnu.org>
5057 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5060 2012-09-22 Kenichi Handa <handa@gnu.org>
5062 * composite.c (composition_reseat_it): Handle the case that a
5063 grapheme cluster is not covered by a single font (Bug#12352).
5065 2012-09-21 Chong Yidong <cyd@gnu.org>
5067 * image.c (define_image_type): Avoid adding duplicate types to
5068 image_types (Bug#12463). Suggested by Jörg Walter.
5070 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5072 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5073 (print_load_command_name): Add case LC_DATA_IN_CODE.
5074 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5076 2012-09-21 Glenn Morris <rgm@gnu.org>
5078 * eval.c (Frun_hook_with_args_until_success)
5079 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5081 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5083 * fileio.c (Ffile_selinux_context): Only call freecon when
5084 lgetfilecon succeeded.
5085 (Fset_file_selinux_context): Likewise. (Bug#12444)
5087 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5089 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5090 reordering, locate the cursor by calling set_cursor_from_row; if
5091 that fails, clear the desired glyph matrix before returning a
5092 failure indication to the caller. Fixes leaving garbled display
5093 when fast scrolling with a down-key. (Bug#12403)
5094 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5095 scrolling through multibyte text.
5097 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5099 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5100 calling mark_vectorlike since that's the one that marks the window.
5101 (mark_discard_killed_buffers): Mark the final cdr.
5102 * window.h (struct window): Move prev/next_buffers to the
5103 non-standard fields.
5104 * window.c (make_window): Initialize prev/next_buffers manually.
5106 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5108 Omit unused arg EXPECTED from socket hooks.
5109 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5110 * nsterm.m (ns_term_init):
5111 * termhooks.h (struct terminal.read_socket_hook):
5112 * w32inevt.c (w32_console_read_socket):
5113 * w32term.c (w32_read_socket):
5114 * xterm.c (XTread_socket):
5115 Omit unused arg EXPECTED. All callers changed.
5116 (store_user_signal_events): Return void, not int, since callers no
5117 longer care about the return value. All uses changed.
5119 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5121 * w32gui.h (XParseGeometry): Do not declare.
5123 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5125 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5126 Ignore 'expected'. See Eli Zaretskii in
5127 <http://bugs.gnu.org/12471#8> (last line).
5129 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5130 (XParseGeometry): Now static. Substitute extremal values for
5131 values that are out of range.
5133 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5135 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5137 * nsfns.m (XParseGeometry): Remove.
5138 (Fx_create_frame): Call x_set_offset to correctly interpret
5139 top_pos in geometry.
5141 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5142 (Fx_parse_geometry): If there is a space in string, call
5143 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5145 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5147 * search.c (scan_buffer): Use character positions in calls to
5148 region_cache_forward and region_cache_backward, not byte
5149 positions. (Bug#12196)
5151 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5152 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5154 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5155 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5156 emacs_blocked_malloc, now deleted.
5158 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5160 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5161 The workaround was for improving performance on Solaris 2.4, but
5162 is getting in the way now. Emacs will still work if someone is
5163 still running Solaris 2.4 in a museum somewhere; Sun dropped
5164 support for Solaris 2.4 in 2003.
5165 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5166 * process.c (create_process) [HAVE_WORKING_VFORK]:
5167 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5168 since Emacs no longer uses vfork on that platform.
5170 2012-09-17 Glenn Morris <rgm@gnu.org>
5172 * emacs.c: Use COPYRIGHT.
5174 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5176 Remove configure's --without-sync-input option (Bug#12450).
5177 When auditing signal-handling in preparation for cleaning it up,
5178 I found that SYNC_INPUT has race conditions and would be a real
5179 pain to fix. Since it's an undocumented and deprecated
5180 configure-time option, now seems like a good time to remove it.
5181 Also see <http://bugs.gnu.org/11080#16>.
5182 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5183 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5184 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5185 (malloc_hysteresis):
5186 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5187 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):

5190 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5191 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5192 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5193 Remove. All uses removed.
5194 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5195 implementation, one that depends on whether the new macro
5196 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5198 * atimer.c (run_timers, handle_alarm_signal):
5199 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5200 (handle_async_input, process_pending_signals)
5201 (handle_input_available_signal, init_keyboard):
5202 * nsterm.m (ns_read_socket):
5203 * process.c (wait_reading_process_output):
5204 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):

5207 * xterm.c (XTread_socket):
5209 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5210 * eval.c (handling_signal): Remove. All uses removed.
5211 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5212 All uses replaced with the SYNC_INPUT version.
5213 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5215 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5218 * font.c (Ffont_shape_gstring): Remove unused local.
5220 2012-09-16 Glenn Morris <rgm@gnu.org>
5222 * Makefile.in (clean): No longer run nextstep's clean.
5224 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5226 (ns-app): Move here from ns.mk, and simplify.
5227 (clean): Simplify nextstep entry.
5228 * ns.mk: Remove file.
5230 2012-09-17 Kenichi Handa <handa@gnu.org>
5232 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5233 not covert the last few charactes.
5235 2012-09-16 Kenichi Handa <handa@gnu.org>
5237 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5238 here, but just check the validity of glyphs in the glyph-string.
5240 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5242 * window.c (Fwindow_parameter, Fset_window_parameter):
5243 Accept any window as argument (Bug#12452).
5245 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5247 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5248 to ns_term_init to avoid memory leak.
5250 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5251 explicit retain/release.
5252 (ns_term_init): Only allow one display. Initialize outerpool and
5255 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5257 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5258 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5259 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5260 the Microsoft problem in a different way, by altering ../nt/config.nt.
5262 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5277 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5278 by lisp.h. This completes removal of setjmp.h inclusion
5279 erroneously announced in the previous commit. (Bug#12446)
5281 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5284 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5285 not defined as a macro. The latter happens on MS-Windows.
5288 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5290 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5291 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5292 Some instances of '#include <setjmp.h>' removed, if the
5293 only reason for the instance was because "lisp.h" was included.
5294 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5295 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5296 and _longjmp with the new symbols. Emacs already uses _setjmp if
5297 available, so this change affects only POSIXish hosts that have
5298 sigsetjmp but not _setjmp, such as some versions of Solaris and
5299 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5300 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5301 (png_load_body) [HAVE_PNG]:
5302 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5303 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5304 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5305 since PNG requires jmp_buf. This is the only exception to the
5306 general rule that we now use sys_setjmp and sys_longjmp.
5307 This exception is OK since this code does not change the signal
5308 mask or longjmp out of a signal handler.
5310 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5312 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5313 Include "syssignal.h", for 'main_thread'.
5315 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5317 Avoid out-of-range marker position (Bug#12426).
5318 * insdel.c (replace_range, replace_range_2):
5319 Adjust markers before overlays, as suggested by comments.
5320 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5321 Remove redundant check before calling offset_intervals.
5323 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5325 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5326 current buffer (Bug#12387).
5328 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5330 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5332 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5334 Use a more backwards-compatible timer format (Bug#12430).
5335 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5336 vector element, not from the 4th, since PSECS is now at the end.
5337 (Fcurrent_idle_time): Doc fix.
5339 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5341 Function to mark objects and remove killed buffers at once.
5342 * alloc.c (discard_killed_buffers): Rename to ...
5343 (mark_discard_killed buffers) ... new name. Add marking
5344 of remaining objects. Fix comment. Adjust users.
5345 (mark_object): Do not touch frame buffer lists here.
5346 * frame.c (delete_frame): Reset frame buffer lists here.
5348 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5350 Better workaround for GNOME bug when --enable-gcc-warnings.
5351 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5352 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5353 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5355 Simplify SIGIO usage (Bug#12408).
5356 The code that dealt with SIGIO was crufty and confusing, e.g., it
5357 played tricks like "#undef SIGIO" but these tricks were not used
5358 consistently. Simplify mostly by not #undeffing standard symbols,
5359 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5360 or not as we please) rather than "defined SIGIO" (standard symbol
5361 that we probably shouldn't #undef).
5362 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5363 Modules that need it can include it.
5364 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5365 * dispextern.h (ignore_sigio): New decl.
5366 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5367 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5368 * emacs.c (shut_down_emacs):
5369 * keyboard.c (kbd_buffer_store_event_hold):
5370 Use ignore_sigio rather than invoking 'signal' directly.
5371 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5373 (FIONREAD, SIGIO): Do not #undef.
5374 (tty_read_avail_input): Use #error rather than a syntax error.
5375 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5376 for I_PIPE, used by SETUP_SLAVE_PTY.
5377 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5378 * sysdep.c (croak): Remove; no longer needed. This bit of
5379 temporary code, with Fred N. Fish's comment that it's temporary,
5380 has been in Emacs since at least 1992!
5381 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5382 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5383 * syssignal.h (croak): Remove decl.
5384 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5385 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5386 now that we're termios-only.
5387 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5388 * term.c (dissociate_if_controlling_tty): Use #error rather than
5391 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5392 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5393 to work around GNOME bug 683906.
5394 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5395 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5396 This works around GCC bug 54561.
5398 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5400 More fixes for 'volatile' and setjmp/longjmp.
5401 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5402 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5403 (png_load_body) [HAVE_PNG]:
5404 (jpeg_load_body) [HAVE_JPEG]:
5405 New function, with most of the old parent function's body.
5406 (png_load) [HAVE_PNG]:
5407 (jpeg_load) [HAVE_JPEG]:
5408 Invoke the new function, to avoid longjmp munging our locals.
5409 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5410 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5411 longjmp is passed 2, as the C standard doesn't guarantee this.
5412 Instead, store the failure code into mgr->failure_code.
5414 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5416 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5417 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5418 (syms_of_keyboard): Remove support for unread-command-char.
5420 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5422 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5423 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5424 violation. (Bug#12426)
5426 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5428 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5430 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5432 * eval.c: Add `inhibit-debugger'.
5433 (Qinhibit_debugger): New symbol.
5434 (call_debugger): Bind it instead of Qdebug_on_error.
5435 (maybe_call_debugger): Test Vinhibit_debugger.
5436 (syms_of_eval): Define inhibit-debugger.
5437 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5438 (syms_of_xdisp): Remove inhibit-debug-on-message.
5440 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5442 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5443 If a nonvolatile local variable is written before a _longjmp to
5444 the frame containing the variable, and is read after the _longjmp,
5445 the value read is indeterminate. Some local variables of type
5446 'struct handler' and 'struct catchtag' are used in this way, so
5447 mark each of their slots as volatile if the slot can be set before
5448 _longjmp and read afterwards.
5449 * lisp.h (struct handler): var and chosen_clause are now volatile.
5450 (struct catchtag): val, next, and pdlcount are now volatile.
5452 * bidi.c (bidi_push_it, bidi_pop_it):
5453 * fns.c (copy_hash_table):
5454 * image.c (define_image_type):
5455 * keyboard.c (kbd_buffer_store_event_hold):
5456 * process.c (Fprocess_send_eof):
5457 * xfaces.c (x_create_gc) [HAVE_NS]:
5458 * xgselect.c (xg_select):
5459 Prefer assignment to memcpy when either will do.
5461 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5462 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5463 time an item is removed. No need to mark this function 'inline';
5464 the compiler knows better than we do.
5466 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5468 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5469 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5470 to change_frame_size (Bug#12388).
5471 (windowDidResize:): Pass YES to updateFrameSize.
5473 * nsterm.h: Add delay parameter to updateFrameSize.
5475 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5477 Discard killed buffers from deleted window and frame objects.
5478 This reduces an amount of references to killed buffers and
5479 helps GC to reclaim them faster.
5480 * alloc.c (discard_killed_buffers): New function.
5481 (mark_object): Use it for deleted windows and frames.
5482 (mark_object): If symbol's value is set up for a killed buffer
5483 or deleted frame, restore its global binding.
5484 * data.c (swap_in_global_binding): Add GC notice.
5485 (swap_in_symval_forwarding): Use convenient set_blv_where.
5486 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5487 * window.h: ... to here.
5489 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5491 Convenient macro to check whether the buffer is live.
5492 * buffer.h (BUFFER_LIVE_P): New macro.
5493 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5494 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5496 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5498 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5499 composition cases (Bug#12364).
5501 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5502 overhang of succeeding glyphs overlapping box cursor.
5504 * w32term.c (x_draw_glyph_string): Likewise.
5506 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5508 Simplify, document, and port floating-point (Bug#12381).
5509 The porting part of this patch fixes bugs on non-IEEE platforms
5510 with frexp, ldexp, logb.
5511 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5513 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5514 support, by removing commented-out code and briefly listing the
5515 C89 functions excluded. The commented-out stuff was confusing
5516 maintenance, e.g., we thought we needed cbrt but it was commented out.
5517 (logb): Remove decl; no longer needed.
5518 (isfinite): New macro, if not already supplied.
5519 (isnan): Don't replace any existing macro.
5520 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5521 are present on all C89 platforms.
5522 (Ffrexp): Do not special-case zero, as frexp does the right thing
5524 (Flogb): Do not use logb, as it doesn't have the desired meaning
5525 on hosts that use non-base-2 floating point. Instead, stick with
5526 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5527 frexp, to avoid getting an unspecified result.
5529 * xdisp.c (Qinhibit_debug_on_message): Now static.
5531 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5533 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5534 NSBezierPath (Bug#12131).
5536 2012-09-10 Chong Yidong <cyd@gnu.org>
5538 * fns.c (Fdelq, Fdelete): Doc fix.
5540 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5542 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5543 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5545 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5547 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5548 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5551 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5553 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5554 left fringe if the window has a left margin. This avoids leaving
5555 traces of the cursor because its leftmost pixel is not drawn over.
5557 * dispnew.c (update_window_line): When the left margin area of a
5558 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5559 that screen line. (Bug#12277)
5561 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5563 Assume C89 or later for math functions (Bug#12381).
5564 This simplifies the code, and makes it a bit smaller and faster,
5565 and (most important) makes it easier to clean up signal handling
5566 since we can stop worring about floating-point exceptions in
5567 library code. That was a problem before C89, but the problem
5568 went away many years ago on all practical Emacs targets.
5569 * data.c, image.c, lread.c, print.c:
5570 Don't include <math.h>; no longer needed.
5571 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5572 might be autoconfigured, as that never happens.
5574 * doprnt.c (DBL_MAX_10_EXP):
5575 * print.c (DBL_DIG):
5576 Remove. C89 or later always defines these.
5577 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5578 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5579 (arith_error, domain_error, domain_error2):
5580 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5581 no longer needed -- we simply return what C returns. All uses removed.
5582 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5584 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5585 Remove. All uses expanded, as these macros are no longer used
5586 more than once and are now more trouble than they're worth.
5587 (Ftan): Use tan, not sin / cos.
5588 (Flogb): Assume C89 frexp.
5589 (fmod_float): Assume C89 fmod.
5590 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5591 (init_floatfns): Remove. All uses removed.
5593 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5595 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5596 compositeToPoint for OSX < 10.6 (Bug#12390).
5598 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5600 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5601 This produces more-accurate results.
5603 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5605 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5606 changes (Bug#12088).
5608 2012-09-08 Chong Yidong <cyd@gnu.org>
5610 * syntax.c (Fstring_to_syntax): Doc fix.
5612 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5614 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5615 in the internal border.
5616 (x_set_window_size): Remove static variables and their usage.
5617 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5618 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5619 Remove fringe/internal border adjustment (Bug#11052).
5620 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5621 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5622 (ns_fix_rect_ibw): Remove.
5623 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5624 (ns_dumpglyphs_box_or_relief): Ditto.
5625 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5627 (ns_dumpglyphs_image): Ditto.
5628 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5630 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5631 their usage. Add fringe_extended_p and its use as in other terms.
5632 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5633 scroll bar was removed.
5634 (updateFrameSize): New function.
5635 (windowDidResize): Move code to updateFrameSize and call it.
5637 * nsterm.h (EmacsView): Add updateFrameSize.
5639 2012-09-07 Chong Yidong <cyd@gnu.org>
5641 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5643 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5645 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5647 More signal-handler cleanup (Bug#12327).
5648 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5649 Problem introduced when merging patches. Noted by Eli Zaretskii in
5650 <http://bugs.gnu.org/12327#67>.
5651 * floatfns.c: Comment fix.
5652 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5653 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5654 and anyway the declaration is harmless even if SIGDANGER is not defined.
5655 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5656 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5657 source files not surprisingly expected syssignal.h to define, or
5658 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5659 Include <sys/ioctl.h>, for FIONREAD.
5660 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5661 This eliminates a problem whereby other files mysteriously had
5662 to include "syssignal.h" before including "systty.h" if they
5663 wanted to use "#ifdef SIGIO".
5665 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5667 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5669 * w32.c (sigemptyset): Empty the set.
5670 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5672 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5674 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5676 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5677 (mark_object): Likewise for frame objects.
5679 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5681 * syssignal.h (handle_on_main_thread): Always declare,
5682 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5683 This ports to platforms without HAVE_PTHREAD.
5685 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5687 Signal-handler cleanup (Bug#12327).
5688 Emacs's signal handlers were written in the old 4.2BSD style with
5689 sigblock and sigmask and so forth, and this led to some
5690 inefficiencies and confusion. Rewrite these to use
5691 pthread_sigmask etc. without copying signal sets around. Also,
5692 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5693 'signal', and instead use functions that do not attempt to take
5694 over the system name space. This patch causes Emacs's text
5695 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5696 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5697 Do not include <signal.h> or "syssignal.h", as these
5698 modules do not use signals.
5699 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5700 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5701 Do not include <signal.h>, as "syssignal.h" does that for us now.
5702 * atimer.c (sigmask_atimers): New function.
5703 (block_atimers, unblock_atimers): New functions,
5704 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5706 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5707 no longer needed here.
5708 * emacs.c (main): Inspect existing signal handler with sigaction,
5709 so that there's no need to block and unblock SIGHUP.
5710 * sysdep.c (struct save_signal): New member 'action', replacing
5711 old member 'handler'.
5712 (save_signal_handlers, restore_signal_handlers):
5713 Use sigaction instead of 'signal' to save and restore.
5714 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5715 New function. All users of 'signal' modified to use set_sighandler
5716 if they're writeonly, and to use sys_signal if they're read+write.
5717 (emacs_sigaction_init, forwarded_signal): New functions.
5718 (sys_signal): Remove. All uses replaced by calls to sigaction
5719 and emacs_sigaction_init, or by direct calls to 'signal'.
5720 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5721 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5722 all uses replaced by pthread_sigmask etc. calls.
5723 * syssignal.h: Include <signal.h>.
5724 (emacs_sigaction_init, forwarded_signal): New decls.
5725 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5726 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5727 (sigmask, sys_sigmask): Remove; no longer needed.
5728 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5729 (sigblock, sigunblock, sigfree):
5730 (sigsetmask) [!defined sigsetmask]:
5731 Remove. All uses replaced by pthread_sigmask.
5732 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5733 no longer need to be replaced, and its typical old uses
5734 are now done via emacs_sigaction_init and sigaction.
5735 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5736 (sys_sigdel): Remove; unused.
5737 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5739 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5741 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5742 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5744 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5746 Explicitly mark buffer_defaults and buffer_local_symbols.
5747 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5748 mark_local_symbols here.
5749 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5750 since special buffers aren't marked here any more.
5751 (allocate_buffer): Chain new buffer with all_buffers here...
5752 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5754 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5755 (syms_of_buffer): Remove staticpro of the above.
5756 (init_buffer_once): Set names for buffer_defaults and
5757 buffer_local_symbols.
5759 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5761 Use bool for booleans in font-related modules.
5762 * font.c (font_intern_prop, font_style_to_value)
5763 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5764 (generate_otf_features, font_check_otf_features, font_check_otf)
5765 (font_match_p, font_list_entities, font_at):
5766 * fontset.c (fontset_id_valid_p, reorder_font_vector
5767 (fontset_find_font, Fset_fontset_font)
5768 (face_suitable_for_char_p) [0]:
5769 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5770 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5771 (m17n_flt_initialized, ftfont_shape_by_flt):
5772 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5773 * nsfont.m (nsfont_draw):
5774 * w32font.c (w32font_draw):
5775 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5776 Use bool for booleans.
5777 * font.h: Adjust to above API changes.
5778 (struct font, struct font_driver, struct font_driver_list):
5779 Use bool for booleans.
5780 (struct font): Remove useless member encoding_type.
5782 * fontset.c, xftfont.c: Omit unnecessary static decls.
5784 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5786 * alloc.c (mark_object): Revert window marking code
5787 since it's unsafe for the Fset_window_configuration.
5789 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5791 Fix race conditions with signal handlers and errno (Bug#12327).
5792 Be more systematic about preserving errno whenever a signal
5793 handler returns, even if it's not in the main thread. Do this by
5794 renaming signal handlers to distinguish between signal delivery
5795 and signal handling. All uses changed.
5796 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5797 * data.c (deliver_arith_signal): Rename from arith_error.
5798 * dispnew.c (deliver_window_change_signal): Rename from
5799 window_change_signal.
5800 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5801 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5802 * keyboard.c (deliver_input_available_signal): Rename from
5803 input_available_signal.
5804 (deliver_user_signal): Rename from handle_user_signal.
5805 (deliver_interrupt_signal): Rename from interrupt_signal.
5806 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5807 (deliver_child_signal): Rename from sigchld_handler.
5808 * atimer.c (handle_alarm_signal):
5809 * data.c (handle_arith_signal):
5810 * dispnew.c (handle_window_change_signal):
5811 * emacs.c (handle_fatal_signal, handle_danger_signal):
5812 * keyboard.c (handle_input_available_signal):
5813 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5814 * process.c (handle_pipe_signal, handle_child_signal):
5815 New functions, with the actual signal-handling code taken from the
5816 original respective signal handlers, sans the sporadic attempts to
5817 preserve errno, since that's now done by handle_on_main_thread.
5818 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5819 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5820 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5822 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5823 Move initialization of main_thread to sysdep.c's init_signals.
5824 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5825 our usage, and simplifies the mainline code.
5826 (record_child_status_change): New static function, as a helper
5827 for handle_child_signal, and with most of the old child handler's
5829 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5830 (handle_child_signal): Use the above.
5831 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5832 Moved here from emacs.c.
5833 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5834 code moved here from emacs.c's main function.
5835 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5836 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5837 This lets callers save and restore errno properly.
5839 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5841 Remove redundant or unused things here and there.
5842 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5843 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5844 * editfns.c (Fcompare_buffer_substrings): Likewise.
5845 * frame.h (struct terminal, struct font_driver_list):
5846 Remove redundant declarations.
5847 * window.h (Qleft, Qright): Likewise.
5849 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5851 Do not mark objects from deleted buffers, windows and frames.
5852 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5853 (mark_object): Likewise for windows and frames.
5855 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5857 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5858 buffer_defaults and buffer_local_symbols as valid objects.
5859 Return special value to denote them.
5861 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5863 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5864 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5865 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5866 (file_name_absolute_p, Fsubstitute_in_file_name):
5867 (check_executable, check_writable, Ffile_accessible_directory_p)
5868 (Fset_file_selinux_context, Fdefault_file_modes)
5869 (Finsert_file_contents, choose_write_coding_system)
5870 (Fwrite_region, build_annotations, a_write, e_write)
5872 * filelock.c (boot_time_initialized, get_boot_time)
5873 (get_boot_time_1, lock_file_1, within_one_second):
5874 * floatfns.c (in_float):
5875 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5876 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5877 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5878 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5879 * window.c (compare_window_configurations):
5880 Use bool for booleans.
5881 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5882 (Fdefault_file_modes): Now mode_t, not int, for modes.
5883 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5884 (internal_delete_file): Now returns void, not a (boolean) int,
5885 since nobody was looking at the return value.
5886 * lisp.h, window.h: Adjust to above API changes.
5888 * xdisp.c (set_message): Simplify and reindent last change.
5890 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5892 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5894 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5896 * eval.c (call_debugger): Make the function non-static so that we
5897 can call it from set_message.
5899 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5900 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5902 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5904 Give more-useful info on a fatal error (Bug#12328).
5905 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5906 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5907 of doing the work ourselves.
5908 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5909 do most of the work.
5910 (fatal_error_backtrace): New function, taken from the guts
5911 of the old fatal_error_signal, but with a new option to output
5913 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5914 info about the signal than just its number.
5915 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5916 * sysdep.c: Include <execinfo.h>
5917 (emacs_backtrace): New function, taken partly from the previous
5918 code of the 'die' function.
5919 (emacs_abort): Call fatal_error_backtrace rather than abort.
5921 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5923 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5924 eager (load-time) macro-expansion.
5925 * lisp.mk (lisp): Add macroexp.
5927 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5929 Simplify redefinition of 'abort' (Bug#12316).
5930 Do not try to redefine the 'abort' function. Instead, redo
5931 the code so that it calls 'emacs_abort' rather than 'abort'.
5932 This removes the need for the NO_ABORT configure-time macro
5933 and makes it easier to change the abort code to do a backtrace.
5934 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5935 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5936 Remove; sysdep.c's emacs_abort now takes its place.
5937 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5938 'abort' changed to use 'emacs_abort'.
5939 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5940 (abort) [!defined abort]: Rename to ...
5941 (emacs_abort): ... new name.
5942 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5943 the place of the old 'abort' in emacs.c.
5944 * w32.c, w32fns.c (abort): Do not #undef.
5945 * w32.c (emacs_abort): Rename from w32_abort.
5947 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5949 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5950 offsets[j].dv, since the y axis of the screen coordinates points
5951 down, while the y axis of the font definition coordinates points
5952 up. This fixes display of Arabic diacritics such as KASRA and
5953 KASRATAN. (Bug#11860)
5955 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>

5958 * alloc.c (test_setjmp, mark_stack):
5959 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5960 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5961 (png_load, my_error_exit, jpeg_load):
5962 * process.c (send_process_trap, send_process):
5963 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5964 The underscored versions are up to 30x faster on some hosts.
5965 Formerly, the code used setjmp+longjmp sometimes and
5966 _setjmp+_longjmp at other times, with no particular reason to
5967 prefer setjmp+longjmp.
5969 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>

6001 won't change, instead of the address of 'initialize', whose
6002 signature just changed from int to bool.
6003 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6004 * msdos.c (fatal_error_in_progress): ... from here.
6005 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6007 (redisplay_internal, unwind_redisplay): Simply clear
6008 REDISPLAYING_P when unwinding, instead of saving its previous,
6009 always-false value and then restoring it.
6011 Clean up some extern decls.
6012 Mostly, this hoists extern decls out of .c files and into .h files.
6013 That way, we're more likely to catch errors if the interfaces change.
6014 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6015 declare xg_mark_data.
6016 * dispextern.h (x_frame_parm_handlers):

6036 Remove now-redundant extern decls.
6037 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6038 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6040 * xfaces.c: Remove unnecessary static decls.
6041 * xterm.c (updating_frame): Remove decl of nonexistent object.
6043 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6044 when building globals.h, as the objects that are not built on
6045 this host are not needed to compile C files on this host.
6047 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6049 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6097 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6099 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6100 more than one grapheme cluster passed to the shaper: compute the
6101 offset adjustment values separately for each cluster. (Bug#11860)
6103 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6104 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6105 about implicit conversions from integer to pointer.
6107 2012-09-01 Daniel Colascione <dancol@dancol.org>
6109 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6110 system used too early.

6163 window system declarations.
6165 * frame.h: Move common functions here: set_frame_menubar,
6166 x_set_window_size, x_sync, x_get_focus_frame,
6167 x_set_mouse_position, x_set_mouse_pixel_position,
6168 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6195 * lisp.h (mark_ttys): Remove prototype.
6196 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

6254 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6255 Add window_closed and button_values. Add void as return value for
6256 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6257 Add process_dialog as new member.

6391 (code_convert_string, code_convert_string_norecord)
6392 (Fset_coding_system_priority):
6393 * fileio.c (Finsert_file_contents):
6394 Use bool for booleans.
6395 * coding.h, lisp.h: Reflect above API changes.
6396 * coding.c: Remove unnecessary static function decls.
6397 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6398 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6399 not a boolean 'int', since callers never look at the return value.
6400 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6401 * coding.h (decoding_buffer_size, encoding_buffer_size)
6402 (emacs_mule_string_char): Remove unused extern decls.
6403 (struct iso_2022_spec, struct coding_system):
6404 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6405 (struct emacs_mule_spec): Remove unused field 'full_support'.
6406 All initializations removed.
6407 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6409 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6411 Fix spare memory change (Bug#12286).
6412 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6413 (valid_lisp_object_p): Likewise.
6415 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6417 * window.c (Fset_window_configuration): Record any window's old
6418 buffer if it's replaced (see Bug#8789). If the new current
6419 buffer doesn't appear in the selected window, go to its old
6422 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6424 Special MEM_TYPE_SPARE to denote reserved memory.
6425 * alloc.c (enum mem_type): New memory type.
6426 (refill_memory_reserve): Use new type for spare memory.
6427 This prevents live_cons_p and live_string_p from incorrect
6428 detection of uninitialized objects from spare memory as live.
6430 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6433 * Makefile.in (.PHONY): versioclean -> versionclean.
6435 Remove unused external symbols.
6436 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6437 * window.c (Qwindow_valid_p, decode_valid_window):
6438 Now static, not extern.
6439 * data.c (Qinterval): Remove; unused.
6440 (syms_of_data): Do not define 'interval'.
6441 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6442 * window.h (decode_valid_window):
6445 * character.c, charset.c, chartab.c: Use bool for booleans.
6446 * character.c (lisp_string_width, string_count_byte8)
6447 (string_escape_byte8):
6448 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6449 (load_charset_map_from_file, map_charset_chars)
6450 (Fdefine_charset_internal, define_charset_internal)
6451 (Fdeclare_equiv_charset, find_charsets_in_text)
6452 (Ffind_charset_region, char_charset, Fiso_charset):
6453 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6454 (sub_char_table_set, sub_char_table_set_range)
6455 (char_table_set_range, optimize_sub_char_table)
6456 (map_sub_char_table):
6457 Use bool for boolean.
6458 * character.c (str_to_unibyte): Omit last boolean argument; it was
6459 always 0. All callers changed.
6460 * character.h, charset.h: Adjust to match previous changes.
6461 * character.h (char_printable_p): Remove decl of nonexistent function.
6462 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6463 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6464 are all boolean, so make them single-bit bitfields.
6466 * lisp.h (ASET): Remove attempt to detect side effects.
6467 It was meant to be temporary and it often doesn't work,
6468 because when IDX has side effects the behavior of IDX==IDX
6469 is undefined. See Stefan Monnier in
6470 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6472 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6474 * lisp.h (functionp): New function (extracted from Ffunctionp).
6475 (FUNCTIONP): Use it.
6476 * eval.c (Ffunctionp): Use it.
6478 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6480 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6481 as that's faster and simpler than static storage. Don't bother
6482 with the g_main_context_query overhead if g_main_context_pending
6483 says no events are pending.
6484 (gfds, gfds_size): Remove these static vars.
6485 (xgselect_initialize): Remove; no longer needed.
6486 All uses and decls removed.
6488 * emacs.c (fatal_error_signal_hook): Remove.
6489 All uses removed. This leftover from old code was always 0.
6491 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6492 * casefiddle.c (casify_object, casify_region):
6493 * casetab.c (set_case_table):
6494 * category.c, category.h (word_boundary_p):
6495 * category.h (CHAR_HAS_CATEGORY):
6496 Use bool for booleans, instead of int.
6498 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6500 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6502 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6504 On assertion failure, print backtrace if available.
6505 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6506 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6507 * Makefile.in (LIB_EXECINFO): New macro.
6510 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6511 * bytecode.c (exec_byte_code):
6512 * callint.c (check_mark, Fcall_interactively):
6513 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6514 (getenv_internal, sync_process_alive, call_process_exited):
6515 * lisp.h (USE_SAFE_ALLOCA):
6516 Use bool for booleans, instead of int.
6517 * lisp.h, process.h: Adjust prototypes to match above changes.
6518 * callint.c (Fcall_interactively): Don't assume the mark's
6519 offset fits in 'int'.
6521 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6523 * buffer.c, buffer.h: Use bool for boolean.
6524 * buffer.c (reset_buffer_local_variables)
6525 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6526 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6527 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6528 (overlay_touches_p, overlay_strings, Foverlay_put)
6529 (report_overlay_modification, call_overlay_mod_hooks):
6530 (mmap_enlarge, mmap_set_vars):
6531 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6532 Use bool for booleans, instead of int.
6533 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6534 since the 1-or-0 return value is always ignored anyway.
6535 (mmap_initialized_p):
6536 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6537 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6539 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6541 * bidi.c: Use bool for boolean.
6542 This is a bit more readable, and makes the text segment of bidi.o
6543 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6544 Presumably it's faster too.
6545 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6547 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6548 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6549 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6550 (bidi_explicit_dir_char, bidi_level_of_next_char)
6551 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6552 Use bool for booleans, instead of int.
6553 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6554 (bidi_unshelve_cache): Adjust decls to match code.
6556 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6558 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6561 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6563 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6564 * atimer.h: Include <stdbool.h>.
6566 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6568 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6569 compile time tests instead of run time tests on systems that do
6571 (FRAME_MAC_P): Remove leftover from deleted code.
6572 * frame.c (syms_of_frame): Remove leftover from deleted code.
6574 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6576 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6578 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6580 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6581 Otherwise, the compiler complains about (A?B:C) where B is void
6582 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6583 (fontset_add): Return void, for FONTSET_ADD.
6585 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6587 * alloc.c: Use bool for booleans.
6588 (gc_in_progress, abort_on_gc)
6589 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6590 (dont_register_blocks) [GC_MALLOC_CHECK]:
6591 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6592 (check_string_bytes, make_specified_string, memory_full)
6593 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6594 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6595 (mark_stack, valid_pointer_p, make_pure_string)
6596 (Fgarbage_collect, survives_gc_p, gc_sweep):
6597 Use bool for booleans, instead of int.
6598 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6599 Remove unused local.
6600 * alloc.c (PURE_POINTER_P):
6601 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6602 * editfns.c (Fformat):
6603 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6605 * fns.c (sweep_weak_table):
6606 * lisp.h (suppress_checking, push_message, survives_gc_p)
6607 (make_pure_string, gc_in_progress, abort_on_gc):
6608 * lread.c (readchar, read1):
6609 * print.c (Fprin1_to_string):
6610 * xdisp.c (push_message):
6611 Use bool for booleans affected directly or indirectly by
6614 Make recently-introduced setters macros.
6615 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6616 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6617 (set_fontset_default, set_fontset_fallback): Rename from their
6618 upper-case counterparts, and make them functions rather than macros.
6619 This is more consistent with the other recently-introduced setters.
6620 These don't need to be inline, since they're local.
6622 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6624 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6625 the loop (Bug#12247).
6627 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6629 * lisp.h (vcopy): Use memcpy rather than our own loop.
6630 This fixes a performance regression introduced by the recent
6631 addition of vcopy. This means 'vcopy' will need to be modified
6632 for a copying collector, but that's OK. Also, tighten the
6633 checking in the assertion.
6635 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6637 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6638 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6639 non-base glyph for the width of the base character, according to
6640 what x_draw_composite_glyph_string_foreground expects.
6641 Generate WADJUST value according to composition_gstring_width's
6642 expectations, to produce correct width of the composed character.
6643 Reverse the sign of the DU offset produced by ScriptPlace.
6645 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6647 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6649 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6651 Avoid direct writes to contents member of struct Lisp_Vector.
6652 * lisp.h (vcopy): New function to copy data into vector.
6653 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6654 * fns.c (Ffillarray): Use ASET.
6655 * keyboard.c (timer_check_2): Use AREF and ASET.
6656 (append_tool_bar_item, Frecent_keys): Use vcopy.
6657 * lread.c (read_vector): Use ASET.
6658 * msdos.c (Frecent_doskeys): Use vcopy.
6659 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6660 (Finternal_merge_in_global_face): Use ASET and vcopy.
6661 * xfont.c (xfont_list_pattern): Likewise.
6663 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6665 * window.c (Fwindow_point): For the selected window always return
6666 the position of its buffer's point.
6667 (Fset_window_point): For the selected window always go in its
6668 buffer to the specified position.
6670 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6672 Setter macros for fontsets.
6673 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6674 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6675 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6678 2012-08-20 Glenn Morris <rgm@gnu.org>
6680 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6681 Don't assume that `ln -f' works.
6683 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6685 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6686 and later about non-assignments with no effect. See discussion at
6687 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6690 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6692 Inline setter functions for Lisp_Objects slots of struct specbinding.
6693 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6696 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6698 * window.c (select_window): Always make selected window's buffer
6701 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6703 Use AREF and ASET for docstrings of category tables.
6704 * category.h (CATEGORY_DOCSTRING): Use AREF.
6705 (SET_CATEGORY_DOCSTRING): Use ASET.
6706 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6708 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6710 Inline setter functions for hash table members.
6711 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6712 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6713 (set_hash_key_and_value, set_hash_index, set_hash_next)
6714 (set_hash_hash): New functions.
6715 * charset.c, fns.c: Adjust users.
6717 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6719 Inline getter and setter functions for per-buffer values.
6720 * buffer.h (per_buffer_default, set_per_buffer_default)
6721 (per_buffer_value, set_per_buffer_value): New functions.
6722 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6723 * buffer.c, data.c: Adjust users.
6725 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6727 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6729 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6731 Rely on <config.h> + <unistd.h> to declare 'environ',
6732 as gnulib does this if the system doesn't.
6733 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6734 Remove declaration. MS-Windows declares it on stdlib.h which is
6735 included by conf_post.h.
6736 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6737 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6738 * vm-limit.c: Include <unistd.h>, for 'environ'.
6740 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6741 (start_of_data): Remove decl; mem-limits.h provides it.
6743 * xdisp.c (handle_invisible_prop): Make it a bit faster
6744 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6746 2012-08-19 Chong Yidong <cyd@gnu.org>
6748 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6751 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6753 * .gdbinit: Use call instead of set when calling a function in the
6756 * data.c (set_internal): Don't use set_blv_found.
6757 (Fkill_local_variable): Likewise.
6759 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6761 * nsfont.m (ns_ascii_average_width): Ensure the string
6762 ascii_printable is initialized with a null-terminated character
6763 array. Otherwise, it can contain undesired extra characters.
6765 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6767 port new setting code to Sun C 5.8 2005/10/13
6768 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6769 Return void, not Lisp_Object. Otherwise, the compiler
6770 complains about (A?B:C) where B is void and C is Lisp_Object
6771 when compiling CHAR_TABLE_SET, due to the recent change to
6772 the API of sub_char_table_set_contents.
6774 2012-08-18 Chong Yidong <cyd@gnu.org>
6776 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6777 for the string case (Bug#3874).
6779 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6781 * buffer.h (BSET): Remove (Bug#12215).
6782 Replace all uses with calls to new setter functions.

6810 * category.c (bset_category_table):
6811 * syntax.c (bset_syntax_table):
6812 New setter functions.
6814 * process.h (PSET): Remove (Bug#12215).
6815 Replace all uses with calls to new setter functions.
6816 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
6817 (PROCESS_INLINE): New macro.
6818 (pset_childp): New setter function.
6819 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
6820 * process.c (PROCESS_INLINE):

7714 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7715 checking subscripts; problem introduced with the recent
7716 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7717 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7718 since it's used in non-static inline functions now.
7720 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

7747 (INLINE_HEADER_END): New macros.
7748 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7773 This how ASET and AREF are supposed to work, and makes
7774 it easier to think about future improvements. See
7775 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

8153 * w32inevt.c: Include w32inevt.h.
8154 (w32_read_console_input): New inline function, calls either
8155 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
8156 w32_console_unicode_input.
8157 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8158 (w32_kbd_patch_key, key_event): Use the codepage returned by
8159 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
8160 (key_event): use uChar.UnicodeChar only if
8161 w32_console_unicode_input is non-zero.
8163 * w32console.c: Include w32heap.h.

8188 * alloc.c (listn): Fix the order the arguments are consed onto the
8191 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8192 enumeration constants, as PURE and HEAP are too general, and clash
8193 with other headers and sources, such as gmalloc.c and the
8194 MS-Windows system headers. All users changed.
8196 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8198 Revert last save_excursion_save and save_excursion_restore changes.
8199 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8209 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8211 Improve GDB symbol export (Bug#12036).
8212 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8213 arms of an 'if', not using conditional expressions; otherwise GDB
8214 complains about the types in the unevaluated arm when the argument
8215 is an integer literal.
8216 (xgetint): Simplify expression.
8217 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8218 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8219 Zaretskii in <http://bugs.gnu.org/12036#13>.
8220 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8221 needed now that we have gdb_make_enums_visible.
8222 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8223 (enum enum_USE_LSB_TAG):
8224 New enum types, packaging up enums that need to be exported to GDB.
8226 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

8242 * xdisp.c (syms_of_xdisp): Likewise.
8243 * xfns.c (syms_of_xfns): Likewise.
8245 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8247 Fast save_excursion_save and save_excursion_restore.
8248 * lisp.h (struct Lisp_Excursion): New data type.
8249 (PVEC_EXCURSION): New pseudovector type.
8250 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8251 to deal with it. Adjust comments.

8264 Fix export of symbols to GDB (Bug#12036).
8265 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8266 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8267 emacs.c, as this is a more-suitable home. Had this been done earlier
8268 the fix for 12036 would have avoided some of the problems noted in
8269 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8270 would have been more obvious.
8271 * emacs.c: Do not include <verify.h>; no longer needed.
8272 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8273 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8274 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8275 Remove; now done in lisp.h.
8276 * lisp.h (PUBLISH_TO_GDB): New macro.
8277 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8278 (DATA_SEG_BITS): Use it.
8279 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8280 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8281 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8282 not be usable in #if. This simplifies things.
8284 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8286 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8288 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8290 Simplify export of symbols to GDB (Bug#12036).
8291 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8292 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8293 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8294 Adjust to changes in lisp.h and emacs.c, by using
8295 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8296 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8297 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8298 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8299 instead of gdb_valbits.
8300 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8301 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8302 instead of gdb_array_mark_flag.
8303 (xboolvector): Get size from $->size, not $->header.size.
8304 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8305 (xreload, hook-run, hookpost-run): Remove.
8306 * emacs.c: Include <verify.h>.
8307 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8308 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8310 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8311 (gdb_USE_LSB_TAG): New enum constants.
8312 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8313 Also define these as enum constants, so they're visible to GDB.
8314 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8315 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8316 as constants, so they're visible to GDB.
8317 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8318 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8319 Now enum constants, not macros, so they're visible to GDB.
8320 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8321 more convenient now. All uses changed.
8322 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8323 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8325 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8332 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8333 add argument, tune behavior, and adjust all callers.
8335 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8337 Use typedef for EMACS_INT, EMACS_UINT.
8338 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8339 than macros. This simplifies debugging in the usual case, since
8340 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8341 and it allows expressions involving EMACS_INT casts.
8342 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8344 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8346 * nsterm.m (ns_read_socket): Return early if there is a modal

8352 that FOCUS-FRAME can be omitted.
8354 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8356 Adjust buffer text indirection counters at the end of Fkill_buffer.
8357 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8358 buffer is definitely dead. This should really fix an issue reported
8359 by Christoph Scholtes again. (Bug#12007).
8360 (init_buffer_once): Initialize indirection counters of
8361 buffer_defaults and buffer_local_symbols (for sanity and safety).
8363 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8365 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8366 and continuation glyphs on tooltip frames, leave them at zero.

8369 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8371 Simplify copy_overlay.
8372 * buffer.c (copy_overlay): Simplify. Use build_marker.

8392 (build_overlay): Add prototype.
8394 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8396 Swap buffer text indirection counters in Fbuffer_swap_text.
8397 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8398 This avoids crash reported by Christoph Scholtes at
8399 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8401 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8403 * nsmenu.m (Popdown_data): New struct.
8404 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8406 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8407 (initWithContentRect): Make imgView and contentView non-static
8408 and autorelease them. Also autorelease img and matrix (Bug#12005).
8409 (dealloc): Remove (Bug#12005).
8411 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8413 Adjust consing_since_gc when objects are explicitly freed.
8414 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
8415 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

8426 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8428 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8429 as it's limited by the amount of memory, not by INT_MAX.
8431 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8433 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8434 in special-event-map. See the discussion at
8435 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
8438 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
8439 info.dwItemData. Fixes crashes on 64-bit Windows.

8493 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8494 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8495 Adjust users accordingly.
8496 * font.h (font_open_by_name): Adjust prototype.

8514 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8515 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8516 'for_each_per_buffer_object_at'.
8517 All uses changed. It's better to use upper-case for macros that
8518 cannot be implemented as functions, to give the reader a clue
8519 that they're special.
8521 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8523 * alloc.c (Fgarbage_collect): Tweak docstring.

8564 * intervals.c (merge_interval_right, merge_interval_left):
8565 Do not zero out this interval if it is absorbed by its children,

8569 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8571 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8572 when invoking (make-bool-vector N t) and N is a positive
8573 multiple of 8 -- the last 8 bits were mistakenly cleared.
8575 Remove some struct layout assumptions in bool vectors.
8576 * alloc.c (bool_header_size): New constant.
8577 (header_size, word_size): Move earlier, as they're now used earlier.
8578 Use 'word_size' in a few more places, where it's appropriate.

8580 padding before the data member of a bool vector.
8581 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather

9085 2012-07-11 Glenn Morris <rgm@gnu.org>
9087 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9088 since nothing has defined it on these platforms.
9090 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
9091 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

9102 2012-07-11 John Wiegley <johnw@newartisans.com>
9104 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9105 function attribute, so we only use it if it exists in the
9108 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9110 Avoid call to strlen in fast_c_string_match_ignore_case.

9157 * s/aix4-2.h (unix): Remove; no longer needed.
9159 EMACS_TIME simplification (Bug#11875).
9160 This replaces macros (which typically do not work in GDB)
9161 with functions, typedefs and enums, making the code easier to debug.
9162 The functional style also makes code easier to read and maintain.
9163 * systime.h: Include <sys/time.h> on all hosts, not just if
9164 WINDOWSNT, since 'struct timeval' is needed in general.
9165 (EMACS_TIME): Now a typedef, not a macro.
9166 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9168 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9172 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9173 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9174 which are not functions. All uses rewritten to use:
9175 (make_emacs_time): New function.
9176 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9177 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9178 not functions. All uses rewritten to use the following, respectively:
9179 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9180 (add_emacs_time, sub_emacs_time): New functions.
9181 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9182 * fileio.c (Fcopy_file):
9183 * xterm.c (XTflash): Get the current time closer to when it's used.
9184 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9192 * gtkutil.c (get_utf8_string):
9194 * nsmenu.m (ns_update_menubar):
9195 * regex.c (regerror):

9198 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9199 (menu_separator_name_p):
9200 * nsmenu.m (ns_update_menubar):
9201 Prefer memcmp to strncmp when either will do.
9202 * nsterm.m: Include <ftoastr.h>.
9204 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9205 Prefer snprintf to strncpy.
9206 * nsterm.m (ns_term_init):
9207 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9208 * nsterm.m (ns_term_init):
9209 Avoid the need for strncpy, by using build_string or
9210 make_unibyte_string directly. Use dtoastr, not snprintf.
9211 * process.c (Fmake_network_process): Diagnose service names that
9212 are too long, rather than silently truncating them or creating
9213 non-null-terminated names.
9214 (Fnetwork_interface_info): Likewise, for interface names.
9215 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9216 Prefer sprintf to strncat.
9217 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9218 Prefer vsnprintf to vsprintf + strncpy.
9220 2012-07-10 Glenn Morris <rgm@gnu.org>
9222 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9223 Clarify fallback case.
9225 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9227 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9228 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9229 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9230 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9231 where argument type is known to be a Lisp_Cons.
9233 2012-07-10 Tom Tromey <tromey@redhat.com>
9235 * bytecode.c (BYTE_CODE_THREADED): New macro.

9243 Optimize pure C strings initialization.
9244 * lisp.h (make_pure_string): Fix prototype.
9245 (build_pure_c_string): New function, defined as static inline. This
9246 provides a better opportunity to optimize away calls to strlen when
9247 the function is called with compile-time constant argument.
9248 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9249 argument, adjust users accordingly. Use build_pure_c_string where
9251 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9252 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9253 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9255 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9257 Avoid calls to strlen in miscellaneous functions.
9258 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9259 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9260 * lread.c (openp): Likewise.
9262 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9264 Avoid calls to strlen in path processing functions.
9265 * fileio.c (file_name_as_directory): Add comment. Change to add
9266 srclen argument and return the length of result. Adjust users
9268 (directory_file_name): Fix comment. Change to add srclen argument,
9269 swap 1st and 2nd arguments to obey the common convention.
9270 Adjust users accordingly.
9271 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9273 2012-07-10 Glenn Morris <rgm@gnu.org>
9275 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9278 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9279 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9280 * s/gnu.h (DATA_START): Move definitions to configure.
9282 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9283 We include usg5-4-common.h, which defines them both.
9285 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9286 O_RDONLY already includes it).
9288 Stop ns builds setting the EMACSLOADPATH environment variable.
9289 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9290 Now it does not set EMACSLOADPATH, just returns the load-path string.
9291 * nsterm.h: Update accordingly.
9292 * lread.c [HAVE_NS]: Include nsterm.h.
9293 (init_lread) [HAVE_NS]: Use ns_load_path.
9294 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9296 2012-07-09 Glenn Morris <rgm@gnu.org>
9298 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9299 since the included bsd-common.h does so.
9301 Stop ns builds setting the EMACSPATH environment variable.
9302 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9303 (ns_init_paths): Do not set EMACSPATH.
9304 * nsterm.h (ns_exec_path): Add it.
9305 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9308 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9310 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9312 * process.c (wait_reading_process_output): 'waitchannels' was unset
9313 when read_kbd || !NILP (wait_for_cell); fix this.
9315 Add GCC-style 'const' attribute to functions that can use it.
9316 * character.h (char_resolve_modifier_mask):
9317 * keyboard.h (make_ctrl_char):
9318 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9319 (init_character_once, next_almost_prime, init_fns, init_image)
9320 (flush_pending_output, init_sound):
9321 * mem-limits.h (start_of_data):
9322 * menu.h (finish_menu_items):
9323 Add ATTRIBUTE_CONST.

9325 Declare the dummy function with ATTRIBUTE_CONST.
9326 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9327 Add decls with ATTRIBUTE_CONST.
9329 Minor improvements to make_formatted_string.
9330 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9331 where int is good enough, as vsprintf returns an int.
9332 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9334 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9336 Use make_formatted_string to avoid double length calculation.
9337 * lisp.h (make_formatted_string): New prototype.
9338 * alloc.c (make_formatted_string): New function.
9339 * buffer.c (Fgenerate_new_buffer_name): Use it.
9340 * dbusbind.c (syms_of_dbusbind): Likewise.
9341 * editfns.c (Fcurrent_time_zone): Likewise.
9342 * filelock.c (get_boot_time): Likewise.
9343 * frame.c (make_terminal_frame, set_term_frame_name)
9344 (x_report_frame_params): Likewise.
9345 * image.c (gs_load): Likewise.
9346 * minibuf.c (get_minibuffer): Likewise.
9347 * msdos.c (dos_set_window_size): Likewise.
9348 * process.c (make_process): Likewise.

9361 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9363 Move marker debugging code under MARKER_DEBUG.
9364 * marker.c (MARKER_DEBUG): Move marker debugging code under
9365 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9366 for bootstrap with --enable-checking (~3x slowdown reported
9367 by Juanma Barranquero <lekktu@gmail.com>).
9368 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9370 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9372 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9373 See <http://bugs.gnu.org/11825#29>.
9375 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9377 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9378 has no font, use the frame's font. (Bug#11813)
9379 (display_line): Add commentary about displaying truncation glyphs
9381 (produce_special_glyphs): Move here from term.c.
9383 * term.c (produce_special_glyphs): Move to xdisp.c.
9385 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9388 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9390 * xdisp.c (display_line): Avoid warning about implicit declaration
9393 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9395 * lisp.h: Remove empty conditional.
9397 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9399 * lread.c (load_path_check): Now static.
9401 Fix some minor --with-ns problems found by static checking.
9402 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9403 (x_set_font) [!HAVE_X_WINDOWS]:
9404 * image.c (xpm_load_image) [HAVE_NS]:
9405 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9406 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9407 Remove unused local.
9408 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9409 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9410 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9411 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9412 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9413 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9414 Fix pointer signedness problem.
9415 * xfaces.c (FRAME_X_FONT_TABLE):
9416 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9418 2012-07-07 Glenn Morris <rgm@gnu.org>
9420 * lread.c (load_path_check): New function, split from init_lread.
9421 (init_lread): Reorganize. Motivation:
9422 If EMACSLOADPATH is set, check/warn about that rather than the
9423 defaults, which we are not going to use. Hence we can remove
9424 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9425 Don't warn if site-lisp directories are missing.
9426 If not installed, start from a blank load-path, since
9427 PATH_LOADSEARCH refers to the eventual installation directories.
9429 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9431 Support truncation and continuation glyphs on GUI frames, when
9432 fringes are disabled. (Bug#11832)
9433 * xdisp.c (init_iterator): Get dimensions of truncation and
9434 continuation glyphs even if on GUI frames.
9435 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9436 or both, are absent.
9437 (start_display, move_it_in_display_line_to): Handle the case of a
9438 GUI frame without a fringe to display continuation or truncation
9440 (insert_left_trunc_glyphs): Support GUI frames: make sure
9441 truncation glyphs overwrite enough glyphs from the current line to
9442 have sufficient space in pixels.
9443 (display_line): Support truncation and continuation glyphs on GUI
9444 frames. If some spare pixels are left on the line after inserting
9445 the truncation glyphs, fill that space with a stretch glyph of a
9446 suitably computed width.
9448 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9449 produce_glyphs, to support GUI sessions.
9451 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9453 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9455 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9457 Do not require float-time's arg to fit in time_t (Bug#11825).
9458 This works better on hosts where time_t is unsigned, and where
9459 float-time is applied to the (negative) difference between two times.
9460 * editfns.c (decode_time_components): Last arg is now double *,
9461 not int *, and means to store all the result as a double, without
9462 worrying about whether the seconds part fits in time_t.
9463 All callers changed.
9464 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9465 All callers changed.
9466 (Ffloat_time): Do not fail merely because the specified time falls
9467 outside of time_t range.
9469 2012-07-07 Glenn Morris <rgm@gnu.org>
9471 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9472 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9473 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9475 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9477 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):

9493 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9495 * xfns.c (Fx_change_window_property): Doc fix.
9496 * w32fns.c (Fx_change_window_property): Doc fix.
9498 * w32fns.c (Fx_window_property): Accept the same arguments as the
9499 X Windows version. Doc fix.
9500 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9502 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9503 Eli Zaretskii <eliz@gnu.org>

9511 * process.c: Avoid unnecessary calls to gettime.
9512 (wait_reading_process_output): Don't get the time of day
9513 when gobbling data immediately and not waiting, as there's no need
9514 for it in that case. This removes a FIXME.
9516 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9518 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9519 is defined (Bug#11768).

9523 Fix marker debugging code.
9524 * marker.c (byte_char_debug_check): Do not perform the check
9525 if buffer is not multibyte.
9526 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9527 Call byte_char_debug_check with correct arguments.
9529 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9531 Compile marker debugging code only if ENABLE_CHECKING is defined.
9532 * marker.c (byte_char_debug_check, count_markers):
9533 Use only if ENABLE_CHECKING is defined.
9534 (byte_debug_flag): Remove.
9535 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9536 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9538 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9540 Avoid code repetition in marker-related functions.
9541 * marker.c (attach_marker): New function.

9544 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9545 Consistently rename charno to charpos.
9546 (marker_position): Add eassert.
9547 (marker_byte_position): Convert to eassert.
9549 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9559 * lisp.h (build_marker): New prototype.
9560 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9561 * composite.c (autocmp_chars): Likewise.
9562 * editfns.c (buildmark): Remove.
9563 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9564 (save_restriction_save): Use build_marker.
9565 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9566 * window.c (save_window_save): Likewise.
9568 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9573 (delete_all_overlays, Fdelete_overlay): Use it.
9574 * minibuf.c (get_minibuffer): Fix comment.
9576 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9578 Port to OpenBSD 5.1 amd64.
9579 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9580 This is needed for OpenBSD, and should be harmless on all BSD systems.
9581 Also, include <sys/sysctl.h>, as it should be available on all
9582 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9583 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9584 use p_pid member, not kp_proc.pid.
9586 2012-07-06 Glenn Morris <rgm@gnu.org>
9588 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9590 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9592 More xmalloc and related cleanup.

9601 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9603 Omit needless casts involving void * pointers and allocation.
9604 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9605 as the former is more robust if P's type is changed.
9606 Prefer xzalloc to xmalloc + memset 0.
9607 Simplify malloc-or-realloc to realloc.
9608 Don't worry about xmalloc returning a null pointer.
9609 Prefer xstrdup to xmalloc + strcpy.
9610 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9612 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9613 alloca of a constant.

9617 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9618 hscroll is larger than the line width. Fixes long and futile
9619 looping inside extend_face_to_end_of_line (on a TTY) producing
9620 glyphs that are not needed and thrown away.
9622 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9624 * marker.c (set_marker_restricted_both): Simplify by using
9627 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9636 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9637 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9638 followed by gtk_box_set_homogeneous (Bug#11768).
9639 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9640 (update_theme_scrollbar_width, xg_create_scroll_bar):
9641 Use gtk_scrollbar_new (Bug#11768).
9642 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9643 (is_box_type): New function (Bug#11768).
9644 (xg_tool_item_stale_p): Call is_box_type.
9645 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9646 with default display (Bug#11768).

9650 * xdisp.c (window_hscroll_limited): New function.
9651 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9652 coordinates when window's hscroll is set to insanely large
9655 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9657 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9716 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9718 * fileio.c (time_error_value): Check the right error number.
9719 Problem reported by Troels Nielsen in
9720 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9724 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9725 This should be fixed in a better way; see Eli Zaretskii in
9726 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9727 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9729 * fileio.c (time_error_value): Rename from special_mtime.
9730 The old name's problems were noted by Eli Zaretskii in
9731 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9733 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9734 This variable's comment says Emacs needs at least one GDB-visible
9735 symbol of type enum pvec_type, to work around GDB problems.
9736 The symbol's value doesn't matter.
9738 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9739 that causes compilation to fail on pre-C99 compilers.
9741 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9743 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9744 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9746 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9754 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9755 * lisp.h (enum pvec_type): Use fewer bits.
9756 (PSEUDOVECTOR_SIZE_BITS): New constant.
9757 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9758 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9759 change in pvec_type.
9760 (PSEUDOVECTOR_TYPEP): New macro.

9766 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9767 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9768 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9769 abusing vector->header.next.nbytes.
9770 (live_vector_p): Use PVEC_TYPE.
9771 (mark_object): Adapt code to extract pvectype. Use switch.
9773 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9775 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9776 Tighten new eassert a bit.
9778 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9780 Fix compilation with --enable-gcc-warnings and -O1
9782 * doprnt.c (doprnt): Change type of tem to int, initialize
9783 to avoid compiler warning. Add eassert.
9784 * search.c (simple_search): Initialize match_byte to avoid
9785 compiler warning. Add eassert.
9787 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9789 Avoid weird behavior with large horizontal scrolls.
9790 Without this change, for example, large hscroll values would
9791 mess up Emacs's display on Fedora 15 x86, presumably due to
9792 overflows in int calculations in the display code.
9793 Also, if buffers had long lines, Emacs would freeze.
9794 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9795 (set_window_hscroll): New function, containing the old guts of
9796 Fset_window_hscroll. Return the clipped value.
9797 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9798 This avoids the need to check against PTRDIFF_MAX.
9800 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9802 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9806 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9808 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9809 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9810 since GCC 4.4.6 issues a bogus warning for them.
9812 Fix bugs in file timestamp newness comparisons.
9813 * fileio.c (Ffile_newer_than_file_p):
9814 * lread.c (Fload): Use full timestamp resolution of files,
9815 not just the 1-second resolution, so that files that are only
9816 slightly newer still count as newer.
9817 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9818 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9820 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9822 * fileio.c: Improve handling of file time marker. (Bug#11852)
9823 (special_mtime): New function.
9824 (Finsert_file_contents, Fverify_visited_file_modtime):
9825 Use it to set special mtime values consistently.

9829 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9830 marker for non-existing file. (Bug#11852)
9832 2012-07-03 Glenn Morris <rgm@gnu.org>
9834 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9835 and did not make it into globals.h).
9837 2012-07-03 Tom Tromey <tromey@redhat.com>

9875 2012-07-03 Glenn Morris <rgm@gnu.org>
9877 * lisp.h (Frandom): Make it visible to C.
9878 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9879 buffer for invisible buffers. (Bug#1229)

9883 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9884 values which aren't power of 2.
9885 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9886 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9889 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9891 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

9897 * alloc.c (allocate_vector_block): Remove redundant
9898 calls to mallopt if DOUG_LEA_MALLOC is defined.
9899 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9900 avoid calls to mallopt if zero_vector is returned.
9902 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9904 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9905 is enabled, avoid dereferencing NULL current_sblock if
9908 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9910 Cleanup basic buffer management.
9911 * buffer.h (struct buffer): Change layout to use generic vector
9912 marking code. Fix some comments. Change type of 'clip_changed'
9913 to bitfield. Remove unused #ifndef old.
9914 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

9920 * alloc.c (allocate_buffer): Adjust to match new layout of
9921 struct buffer. Fix comment.

9924 Lisp area of struct buffer.
9925 (mark_object): Use it. Adjust marking of misc objects
9926 and related comments.
9928 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9930 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9931 wrapper that is not needed because the wrapped code is a no-op (zero
9932 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9933 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9935 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9937 * alloc.c (mark_buffer): Simplify. Remove prototype.
9938 (mark_object): Add comment. Reorganize marking of vector-like
9939 objects. Use CHECK_LIVE for all vector-like objects except buffers
9940 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9941 Avoid redundant calls to mark_vectorlike for bool vectors.
9943 2012-06-30 Glenn Morris <rgm@gnu.org>
9945 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9947 * epaths.in (PATH_SITELOADSEARCH): New.
9948 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9949 This is rather than relying on --enable-locallisppath elements
9950 having "site-lisp" in their names. (Bug#10208#25, 11658)
9952 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9954 * w32proc.c (sys_select): Accept and ignore one more argument.
9956 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9958 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9959 (pselect) [!MS_DOS]: Redirect to sys_select.
9961 * sysdep.c: Don't include dos.h and dosfns.h.
9963 * process.c (sys_select):
9964 * msdos.c (sys_select): Accept one more argument and ignore it.
9966 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9967 adapt data types and code to that.
9970 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9971 which clashes with the gnulib function of the same name.
9973 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9975 * font.c (font_style_to_value, font_style_symbolic)

9979 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9981 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9984 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9986 * xdisp.c (try_window_id): Undo last change.
9988 * w32.c (getwd): Adjust commentary about startup_dir.
9989 (init_environment): Always call sys_access, even in non-MSVC
9990 builds. Don't chdir to the directory of the Emacs executable.
9991 This undoes code from 1997 which was justified by the need to
9992 "avoid conflicts when removing and renaming directories". But its
9993 downside was that every relative file name was being interpreted
9994 relative to the directory of the Emacs executable, which can never
9995 be TRT. In particular, it broke sys_access when called with
9996 relative file names.
9997 (sys_access): Map GetLastError to errno.
9999 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10005 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10008 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

10011 Add QUIT to make the loop interruptible.
10013 2012-06-29 Glenn Morris <rgm@gnu.org>

10028 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10034 Avoid integer overflow on scroll-left and scroll-right.
10035 * window.c (HSCROLL_MAX): New macro.
10036 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10037 overflow when requested scroll falls outside ptrdiff_t range.
10039 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10041 * window.h (struct window): Change type of 'hscroll',
10042 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10043 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10044 Adjust users accordingly.
10045 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10046 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10047 from EMACS_INT to ptrdiff_t.

10123 * alloc.c (allocate_string): Omit intervals initialization.
10124 * alloc.c (make_uninit_multibyte_string): Initialize intervals

10149 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10150 when building with Clang.

10181 * alloc.c: Remove build_string.
10182 * lisp.h: Define build_string as static inline. This provides

10184 function is called with compile-time constant argument.
10185 * image.c (imagemagick_error): Convert to build_string.

10189 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10191 Use sprintf return value instead of invoking strlen on result.
10192 In the old days this wasn't portable, since some sprintf
10193 implementations returned char *. But they died out years ago and
10194 Emacs already assumes sprintf returns int.
10195 Similarly for float_to_string.
10196 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10202 * xdisp.c (message_dolog):
10203 * xfns.c (syms_of_xfns):
10204 Use sprintf or float_to_string result to avoid need to call strlen.
10205 * data.c (Fnumber_to_string):
10206 Use make_unibyte_string, since the string must be ASCII.
10207 * lisp.h, print.c (float_to_string): Now returns int length.
10208 * term.c (produce_glyphless_glyph):
10209 Use sprintf result rather than recomputing it.
10211 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10212 * Makefile.in (ALL_CFLAGS):
10213 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10214 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10216 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10218 * dispextern.h (xstrcasecmp): Define to library function
10219 strcasecmp if available.

10237 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10238 sprintf already null-terminates its output.
10240 * xfns.c (x_window): Remove redundant cast.
10242 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10244 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10245 `const char *' to `char *' to avoid compiler warning.
10247 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10249 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10250 instead of truncating it to 63 (admittedly a generous limit).
10252 * process.c: Fix spelling and caps in comments.
10254 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10256 * emacs.c (setpgrp): Remove definition, unused.

10266 (SYSTIME_H): Add nt/inc/sys/time.h.
10268 * systime.h [WINDOWSNT]: Include sys/time.h.
10270 * s/ms-w32.h (struct timespec): Definition moved from

10303 Remove unnecessary forward decls.
10305 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10307 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10308 * lisp.h (WAIT_READING_MAX): New macro.
10309 * dispnew.c (Fsleep_for, sit_for):
10310 * keyboard.c (kbd_buffer_get_event):
10311 * process.c (Faccept_process_output):
10312 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10313 This improves on the previous patch, which introduced a bug
10314 when time_t is unsigned and as wide as intmax_t.
10315 See <http://bugs.gnu.org/9000#51>.
10317 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10333 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10334 Privately reported by Herbert J. Skuhra.
10335 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10337 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10338 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10340 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10343 last argument of make_unibyte_string.
10345 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10346 language ID in the event parameters.
10348 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10349 event.code, not the obscure "character set ID".
10351 2012-06-23 Chong Yidong <cyd@gnu.org>
10353 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10362 * s/ms-w32.h (pselect): Redirect to sys_select.
10364 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
10366 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
10367 in the logic of incrementing and decrementing the value of
10368 use_relocatable_buffers.

10372 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.

10382 Support higher-resolution time stamps (Bug#9000).
10383 The time stamps are only nanosecond-resolution at the C level,
10384 since that's the best that any real-world system supports now.
10385 But they are picosecond-resolution at the Lisp level, as that's
10386 easy, and leaves room for future OS improvements.
10388 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10391 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10392 Don't get current time unless it's needed.
10394 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10395 now provides it if it's absent.
10396 (start_atimer): Port to higher-res time stamps.
10397 Check for time stamp overflow. Don't get current time more
10398 often than is needed.
10400 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10401 Include systime.h, not time.h.
10402 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10404 * dired.c: Include stat-time.h.
10405 (Ffile-attributes): File times now have higher resolution.
10407 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10408 (struct image): Timestamp now has higher resolution.
10410 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10411 has at least microseconds now. All uses removed.
10412 (update_frame, update_single_window, update_window, update_frame_1)
10413 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10414 (duration_to_sec_usec): Remove; no longer needed.
10416 * editfns.c (time_overflow): Now extern.
10417 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10418 (float-time, Fformat_time_string, Fcurrent_time_string)
10419 (Fcurrent_time_zone): Accept and generate higher-resolution
10421 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10422 (decode_time_components, lisp_seconds_argument): New functions.
10423 (make_time): Now static.
10424 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10425 Report an error if the time is invalid, rather than having the caller
10428 * fileio.c: Include <stat-time.h>
10429 (Fcopy_file): Copy higher-resolution time stamps.
10430 Prefer to set the time stamp via a file descriptor if that works.

10444 Check for time stamp overflow.
10445 (read_char, kbd_buffer_get_event, timer_start_idle)
10446 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10447 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10448 Port to higher-resolution time stamps. Do not assume time_t is signed.
10449 (decode_timer): New function. Timers are now vectors of length 9,
10450 not 8, to accommodate the picosecond component.
10451 (timer_check_2): Use it.
10453 * nsterm.m (select_timeout, timeval_subtract): Remove.
10454 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10455 as they're a bit more accurate and handle overflow better.
10456 (ns_select): Change prototype to be compatible with pselect.
10457 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10458 * nsterm.h (ns_select): Adjust prototype.
10460 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

10475 (wait_reading_process_output):
10476 Port to ns-resolution time stamps.
10477 (Faccept_process_output, wait_reading_process_output):
10478 Check for time stamp overflow. Do not assume time_t is signed.
10479 (select_wrapper): Remove; we now use pselect.
10480 (Fprocess_attributes): Now generates ns-resolution time stamps.
10482 * sysdep.c: Include utimens.h. Don't include utime.h
10483 or worry about struct utimbuf; gnulib does that for us now.
10484 (gettimeofday): Remove; gnulib provides a substitute.
10485 (make_timeval): New function.
10486 (set_file_times): Now sets ns-resolution time stamps.
10487 New arg FD; all uses changed.

10490 Now returns ns-resolution time stamp. All uses changed.
10491 Check for time stamp overflow.
10493 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10494 provides a substitute now.
10496 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10497 since it guarantees struct timespec.
10498 (EMACS_TIME): Now struct timespec, so that we can support
10499 ns-resolution time stamps.
10500 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10501 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10502 (EMACS_USECS): Remove.
10503 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10504 so multiply the arg by 1000 before storing it.
10505 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10507 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10514 (make_timeval, make_lisp_time, decode_time_components): New decls.
10515 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10516 that it mishandled time_t overflow. You can't compare by subtracting!
10517 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10518 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10520 * term.c: Include <sys/time.h>.

10525 in the undo buffer.
10526 (Fprimitive_undo): Use them when restoring time stamps.
10528 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10529 (w32_get_internal_run_time):
10530 Port to higher-resolution Emacs time stamps.
10531 (ltime): Now accepts single 64-bit integer, as that's more convenient
10534 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10536 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10537 for compatibility with pselect. Support ns-resolution time stamps.
10539 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10541 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10542 Check for time stamp overflow, and support ns-resolution time stamps.
10544 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10545 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10546 (timeval_subtract): Remove; no longer needed.
10547 (XTflash, XTring_bell, x_wait_for_event):
10548 Port to ns-resolution time stamps. Don't assume time_t is signed.

10554 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10556 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10557 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10558 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10559 staticidx goes up to 1597 out of 1600 = 0x640.)
10561 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10563 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10564 Otherwise, the umask might be mistakenly 0 while handling input signals.
10566 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10568 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10574 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10575 access to `contents' member of Lisp_Vector objects with AREF and ASET
10578 2012-06-19 Chong Yidong <cyd@gnu.org>
10580 * frame.c (delete_frame): When selecting a frame on a different
10581 text terminal, do not alter the terminal's top-frame.

10585 (unwind_format_mode_line): Restore them.
10586 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10588 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10597 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10598 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10599 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10600 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10601 (METER_1, METER_2): Simplify.
10603 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

10607 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10609 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10610 gets killed during executing of this function (Bug#11665).
10611 Try to always return Qt when the buffer has been actually killed.
10612 (Vkill_buffer_query_functions): In doc-string say that functions
10613 run by this hook should not change the current buffer.
10615 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10617 Fix recently-introduced process.c problems found by static checking.

10637 * lisp.h (eassert): Assume C89 or later.
10638 This removes the need for CHECK.
10639 (CHECK): Remove. Its comments about always evaluating its
10640 argument were confusing, as 'eassert' typically does not evaluate
10643 * coding.c (produce_chars): Use ptrdiff_t, not int.
10645 * xterm.c (x_draw_underwave): Check for integer overflow.
10646 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10833 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10834 Use an inline function on all platforms when using the union type,
10835 since this is simpler and 'static inline' can be used portably

10952 adjust comment accordingly.
10953 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10954 to denote vector blocks. Adjust users (live_vector_p,

10977 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10979 * doprnt.c (doprnt): Truncate multibyte char correctly.
10980 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10981 would mishandle a string argument "Xc" if X was a multibyte
10982 character of length 2: it would truncate after X's first byte
10983 rather than including all of X.
10985 2012-06-06 Chong Yidong <cyd@gnu.org>
10987 * buffer.c (word_wrap): Doc fix.

11034 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11036 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11037 Convert pctcpu and pctmem to Lisp float properly.
11038 Let the compiler fold better, as 100.0/0x8000 is exact.
11040 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11042 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11052 bitfields where appropriate, remove unused fields.
11053 * window.h (struct window): Remove unused 'last_mark_x' and
11054 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11055 change its type from Lisp_Object to bitfield.
11056 Change type of 'force_start', 'optional_new_start',
11057 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11058 fields from Lisp_Object to bitfield. Adjust users accordingly.
11060 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11062 Pacify gcc -Wdouble-precision when using Xaw.
11063 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11064 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11065 Use 'float' consistently, rather than 'float' in most places
11066 and 'double' in a couple of places.
11068 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11070 * xdisp.c (handle_stop): Detect whether we have overlay strings
11071 loaded by testing it->current.overlay_string_index to be
11072 non-negative, instead of checking whether n_overlay_strings is
11073 positive. (Bug#11587)
11075 2012-05-31 Chong Yidong <cyd@gnu.org>
11077 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11083 * search.c (search_buffer): Remove calls to
11084 r_alloc_inhibit_buffer_relocation, as it is now called by
11085 maybe_unify_char, which was the cause of relocation of buffer text
11088 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11090 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11091 for the duration of call to load_charset, to avoid problems with
11092 callers of maybe_unify_char that access buffer text through C
11095 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11096 decrement the inhibition flag, instead of just setting or
11099 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11101 Remove obsolete '#define static' cruft.
11102 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11103 This #undef was "temporary" in 2000; it is no longer needed
11104 now that '#define static' has gone away.
11105 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11106 (gray_bitmap_bits): Remove; no longer needed.
11107 All uses replaced with definiens.

11114 * dispnew.c (__executable_start): Rename from safe_bcopy.
11115 Define only on platforms that need it.
11116 * emacs.c: Include <sys/gmon.h> when profiling.
11117 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11118 (__executable_start): Remove decl, since lisp.h does it now.
11119 (safe_bcopy): Remove decl; no longer has that name.
11120 (main): Coalesce #if into single bit of code, for simplicity.
11121 Cast pointers to uintptr_t, since standard libraries want integers
11123 * lisp.h (__executable_start): New decl.
11125 2012-05-31 Glenn Morris <rgm@gnu.org>
11127 * image.c (Fimagemagick_types): Doc fix.

11150 Do not create empty overlays with the evaporate property (Bug#9642).
11151 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11152 Bug#9642, but explicitly check that the buffer the overlay would
11153 be moved to is live and rearrange lines to make sure that errors
11154 will not put the overlay in an inconsistent state.
11155 (Fdelete_overlay): Cosmetics.
11157 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11159 * w32term.c (my_bring_window_to_top): New function.
11160 (x_raise_frame): Use handle returned by DeferWindowPos, which
11161 could be different from the original one.

11175 to not catch an out-of-range value.
11177 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11179 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11193 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11194 Only r_alloc_inhibit_buffer_relocation needed to be added;
11195 the others were already declared.
11197 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11198 before checking whether it's out of range. Put the check inside
11200 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11202 2012-05-27 Ken Brown <kbrown@cornell.edu>

11214 they are now on lisp.h.
11216 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11218 * search.c (search_buffer): Use it to inhibit relocation of buffer
11219 text while re_search_2 is doing its job, because re_search_2 is
11220 passed C pointers to buffer text. (Bug#11519)
11222 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11223 Update value to 24.
11225 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11226 state after an additional call to move_it_in_display_line_to, keep
11227 the values of it->max_ascent and it->max_descent found for the
11229 (pos_visible_p): Revert the comparison against bottom_y to what it
11230 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11233 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11235 Fix coding-related core dumps with gcc -ftrapv.
11236 The code was computing A - B, where A and B are pointers, and B is
11237 random garbage. This can lead to core dumps on platforms that
11238 have special pointer registers, and it also leads to core dumps on
11239 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11240 A - B only when B is initialized properly.
11241 * coding.c (coding_set_source, coding_set_destination): Return void.
11242 (coding_change_source, coding_change_destinations): New functions,
11243 with the old behaviors of coding_set_source and coding_set_destination.

11257 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11259 (initialize_w32_display): Initialize mouse-highlight data.
11261 * w32inevt.c: Include termchar.h and window.h.
11262 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11263 moves, call note_mouse_highlight. If help_echo changed, call
11264 gen_help_event to produce help-echo message in the echo area.
11265 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11268 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11270 * lread.c (read1): Simplify slightly to avoid an overflow warning
11271 with GCC 4.7.0 on x86-64.
11273 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11275 * bidi.c (bidi_mirror_char): Revert last change: an int is
11276 definitely wide enough here.

11288 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11290 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11291 (allocate_pseudovector):
11292 Use int, not EMACS_INT, where int is wide enough.
11293 (inhibit_garbage_collection, Fgarbage_collect):
11294 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11295 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11296 int might not be wide enough.

11314 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11315 (validate_region): Omit unnecessary test for b <= e,
11316 since that's guaranteed by the previous test.
11317 (adjust_overlays_for_delete): Avoid pos + length overflow.
11318 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11319 (report_overlay_modification):
11320 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11321 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11322 Omit pointer cast, which isn't needed anyway, and doesn't work
11323 after the EMACS_INT -> ptrdiff_t change.
11324 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11325 * buffer.h: Adjust decls to match defn changes elsewhere.
11326 (struct buffer_text, struct buffer):
11327 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11328 Use EMACS_INT, not int, where int might not be wide enough.
11329 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11330 not int, to avoid needless 32-bit limit on 64-bit hosts.
11331 (exec_byte_code): Use tighter memory-full test, one that checks
11332 for alloca overflow. Don't compute the address of the object just
11333 before an array, as that's not portable. Use EMACS_INT, not
11334 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11335 * callint.c (Fcall_interactively):
11336 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11337 * callproc.c (call_process_kill, Fcall_process):
11338 Don't assume pid_t fits into an Emacs fixnum.

11348 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11349 (casify_object): Avoid integer overflow when overallocating buffer.
11350 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11351 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11352 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11353 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11354 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

11357 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11358 For CCL_MapSingle, check that content and value are in int range.
11359 (ccl_driver, Fregister_code_conversion_map):
11360 Check that Vcode_version_map_vector is a vector.
11361 (resolve_symbol_ccl_program): Check that vector header is in range.
11362 Always copy the vector, so that we can check its contents reliably
11363 now rather than having to recheck each instruction as it's being
11364 executed. Check that vector words fit in 'int'.
11365 (ccl_get_compiled_code, Fregister_ccl_program)
11366 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11367 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

11369 contents are in range.
11370 (Fccl_execute_on_string): Check that status is in range.
11371 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11372 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11373 Accept and return EMACS_INT, not int, because callers can pass values
11374 out of 'int' range.

11380 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11381 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11382 avoid mishandling large integers.

11391 Remove now-unnecessary CHECK_NATNUMs.
11392 (Fdefine_charset_internal): Check ranges here, more carefully.
11393 Don't rely on undefined behavior with signed left shift overflow.
11394 Don't assume unsigned int fits into fixnum, or that fixnum fits
11395 into unsigned int. Don't require max_code to be a valid fixnum;
11396 that's not true for gb10830 4-byte on a 32-bit host. Allow
11397 invalid_code to be a cons, for the same reason. Require code_offset
11398 to be a character. Avoid int overflow if max_char is close
11400 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11401 this is intended anyway and avoids some undefined behavior.
11402 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11403 INDEX_TO_CODE_POINT, as that's what it expects.
11404 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11405 * charset.h (DECODE_CHAR): Return int, not unsigned;
11406 this is what was intended anyway, and it avoids undefined behavior.
11407 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11408 integer-overflow issues.
11409 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11410 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11411 where the argument is EMACS_INT, and this behavior is not intended.
11412 * chartab.c (Fmake_char_table, Fset_char_table_range)
11413 (uniprop_get_decoder, uniprop_get_encoder):
11414 Don't assume fixnum fits in int.
11415 * cmds.c (move_point): New function, that does the gist of
11416 Fforward_char and Fbackward_char, but does so while checking
11417 for integer overflow more accurately.
11418 (Fforward_char, Fbackward_char): Use it.
11419 (Fforward_line, Fend_of_line, internal_self_insert)
11420 (internal_self_insert):
11421 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12071 may come from Lisp.

12080 2012-05-25 Glenn Morris <rgm@gnu.org>
12082 * lisp.mk (lisp): Update for more files being compiled now.
12084 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12086 * lread.c: Remove `read_pure' which makes no difference.
12087 (read_pure): Remove var.
12088 (unreadpure): Remove function.
12089 (readevalloop): Don't call read_list with -1 flag.
12090 (read1, read_vector): Don't test read_pure any more.

12102 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12104 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12107 This directory predates autoconf and is no longer needed nowadays.
12108 Move its few remaining bits of functionality to where they're needed.
12109 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

12119 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12120 (BITS_PER_EMACS_INT): New constants, replacing
12121 what used to be in config.h, but not useful in #if.
12122 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12123 define them any more.
12124 (VAL_MAX): New macro.
12126 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12127 BITS_PER_EMACS_INT, in #if.
12128 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12129 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12130 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12131 * s/ms-w32.h (DATA_START):
12132 Move here from removed file m/intel386.h.
12133 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12134 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12136 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12138 Assume C89 or later.
12139 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12140 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12142 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

12161 2012-05-19 Ken Brown <kbrown@cornell.edu>
12163 * xfns.c (x_in_use): Remove `static' qualifier.
12164 * xterm.h (x_in_use): Declare.
12165 * xgselect.c: Include xterm.h.
12166 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12167 and `display_arg' (bug#9754).
12169 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12171 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12173 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12174 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12176 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12178 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12180 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12181 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12183 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12184 reference to image_cache->refcount.
12185 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12187 2012-05-17 Juri Linkov <juri@jurta.org>
12189 * search.c (Fword_search_regexp, Fword_search_backward)
12190 (Fword_search_forward, Fword_search_backward_lax)
12191 (Fword_search_forward_lax): Move functions to isearch.el
12192 (bug#10145, bug#11381).
12194 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12196 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12198 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12200 * lread.c (init_obarray): Declare Qt and Qnil as special.
12202 2012-05-14 Glenn Morris <rgm@gnu.org>
12204 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12205 Put "libexec" before "bin", for the sake of init_callproc_1.
12207 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12209 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12211 * unexaix.c: Port to more-recent AIX compilers.
12212 (report_error, report_error_1, make_hdr, copy_sym)
12213 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12214 Make arguments const char *, not char *, to avoid violations of C
12215 standard and to fix some AIX warnings reported by Gilles Pion.
12217 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12219 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12220 already have overlays loaded.
12221 (handle_single_display_spec): Before returning without displaying
12222 fringe bitmap, synchronize the bidi iterator with the main display
12223 iterator, by calling iterate_out_of_display_property.
12224 (iterate_out_of_display_property): Detect buffer iteration by
12225 testing that it->string is a Lisp string.
12226 (get_next_display_element): When the current object is exhausted,
12227 and there's something on it->stack, call set_iterator_to_next to
12228 proceed with what's on the stack, instead of returning zero.
12229 (set_iterator_to_next): If called at the end of a Lisp string,
12230 proceed to consider_string_end without incrementing string
12231 position. Don't increment display vector index past the end of
12232 the display vector. (Bug#11417)
12233 (pos_visible_p): Don't report a position visible when move_it_to
12234 stopped at the last line of window, which happens to be scanned
12235 backwards by the bidi iteration. (Bug#11464)
12237 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12239 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12240 and right-margin display specs even if the spec is invalid or we
12241 are on a TTY, and thus unable to display on the fringes.
12242 That's because the text with the property will not be displayed anyway,
12243 so we need to signal to the caller that this is a "replacing"
12244 display spec. This fixes display when the spec is invalid or we
12247 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12249 * unexaix.c (make_hdr): Fix typo in prototype.
12250 This bug broke the build on AIX. Problem reported by Gilles Pion.
12252 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12254 * keyboard.c (kbd_buffer_get_event): Read special events also in
12255 batch mode. (Bug#11415)
12257 2012-05-12 Glenn Morris <rgm@gnu.org>
12259 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12261 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12263 * lisp.mk (lisp): Add newcomment.elc.
12265 2012-05-12 Glenn Morris <rgm@gnu.org>
12267 * Makefile.in (MKDIR_P): New, set by configure.
12268 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12270 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12272 Remove unused function hourglass_started.
12273 * dispextern.h (hourglass_started):
12274 * w32fns.c (hourglass_started):
12275 * xdisp.c (hourglass_started): Remove.
12277 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12279 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12280 Update dependencies.
12282 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12284 * xgselect.c (xg_select): Put maxfds+1 into a var.
12285 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12287 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12289 2012-05-10 Dave Abrahams <dave@boostpro.com>
12291 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12292 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12294 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12296 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12297 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12298 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12299 Initialize xd_registered_buses.
12301 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12303 Untag more efficiently if USE_LSB_TAG.
12304 This is based on a proposal by YAMAMOTO Mitsuharu in
12305 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12306 For an admittedly artificial (nth 8000 longlist) benchmark on
12307 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12308 Emacs's overall text size by 1%.
12309 * lisp.h (XUNTAG): New macro.
12310 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12311 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12312 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12313 * eval.c (Fautoload):
12314 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12315 * frame.h (XFRAME): Use XUNTAG.
12317 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12318 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12319 Remove unportable assumptions about print widths of types like
12321 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12322 intptr_t when converting between pointer and integer, to avoid GCC
12323 warnings about wrong width.
12325 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12327 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12328 stack for each reader_thread, instead of defaulting to 8MB
12329 determined by the linker. This avoids failures in creating
12330 subprocesses on Windows 7, see the discussion in this thread:
12331 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12333 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12335 Fix up display of the *Minibuf-0* buffer in the mini window.
12336 * keyboard.c (read_char): Don't clear the echo area if there's no
12338 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12339 contents of *Minibuf-0*) if there's no message displayed in its stead.
12341 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12343 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12346 2012-05-06 Chong Yidong <cyd@gnu.org>
12348 * lisp.mk (lisp): Update.
12350 2012-05-05 Jim Meyering <meyering@redhat.com>
12352 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12354 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12356 * data.c (PUT_ERROR): New macro.
12357 (syms_of_data): Use it. Add new error type `user-error'.
12358 * undo.c (user_error): New function.
12359 (Fprimitive_undo): Use it.
12360 * print.c (print_error_message): Adjust print style for `user-error'.
12361 * keyboard.c (user_error): New function.
12362 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12364 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12366 Do not limit current-time-string to years 1000..9999.
12367 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12368 (Fcurrent_time_string): Support any year that is supported by the
12369 underlying localtime representation. Don't use asctime, as it
12370 has undefined behavior for years outside the range -999..9999.
12372 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12374 Fix race conditions involving setenv, gmtime, localtime, asctime.
12375 Without this fix, interrupts could mess up code that uses these
12376 nonreentrant functions, since setting TZ invalidates existing
12377 tm_zone or tzname values, and since most of these functions return
12378 pointers to static storage.
12379 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12380 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12381 Grow the critical sections to include not just invoking
12382 localtime/gmtime, but also accessing these functions' results
12383 including their tm_zone values if any, and any related TZ setting.
12384 (format_time_string): Last arg is now struct tm *, not struct tm **,
12385 so that the struct tm is saved in the critical section.
12386 All callers changed. Simplify allocation of initial buffer, partly
12387 motivated by the fact that memory allocation needs to be outside
12388 the critical section.
12390 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12392 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12393 with RESET_INTERVAL.

12404 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12406 * xdisp.c (pos_visible_p): If already at a newline from the
12407 display string before the 'while' loop, don't walk back the glyphs
12408 from it3.glyph_row. Solves assertion violation when the display
12409 string begins with a newline (egg.el). (Bug#11367)
12411 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>

12419 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12420 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12421 All were removed before 23.1.
12423 * dispnew.c: Remove HAVE_LIBNCURSES test;
12424 it is always true on relevant platforms.
12426 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12427 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

12439 Do not avoid creating empty evaporating overlays (Bug#9642).
12440 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12441 That is, do not delete an evaporating overlay if it becomes
12442 empty after its bounds are adjusted to fit within its buffer.
12443 This fix caused other problems, and I'm reverting it until we get
12444 to the bottom of them.
12446 2012-04-27 Chong Yidong <cyd@gnu.org>
12448 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12450 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12452 * xdisp.c (pos_visible_p): If the window start position is beyond
12453 ZV, start the display from buffer beginning. Prevents assertion
12454 violation in init_iterator when the minibuffer window is scrolled
12455 via the scroll bar.
12457 * window.c (window_scroll_pixel_based): Likewise.
12459 2012-04-27 Chong Yidong <cyd@gnu.org>

12466 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12468 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12470 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12471 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12473 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12475 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12476 display element, check also the underlying string or buffer
12477 character. (Bug#11341)
12479 * w32menu.c: Include w32heap.h.
12480 (add_menu_item): If the call to AppendMenuW (via
12481 unicode_append_menu) fails, disable Unicode menus only if we are
12482 running on Windows 9X/Me.
12484 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12486 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12487 (xgetint): Add missing shift for LSB tags.
12489 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12491 * keyboard.c (read_char): Don't wipe echo area for select window
12492 events: These might get delayed via `mouse-autoselect-window'

12497 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12498 manipulation of :loaded-from data.
12500 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12502 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12503 now a cons (bug#11311).
12505 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12507 Do not create empty overlays with the evaporate property (Bug#9642).
12508 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12509 if it becomes empty after its bounds are adjusted to fit within
12510 its buffer. Without this fix, in a nonempty buffer (let ((o
12511 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12512 yields an empty overlay that has the evaporate property, which is
12513 not supposed to happen.

12536 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12537 (__malloc_size_t, __malloc_ptrdiff_t):
12538 Remove. All uses removed, replaced by the definiens if needed,
12539 since we can assume C89 or better now.

12628 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12630 * sysdep.c [__FreeBSD__]: Minor cleanups.
12631 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12632 Use Emacs indenting style more consistently. Avoid some casts.

12647 It is never used otherwise.
12649 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12651 * print.c (print_preprocess): Only check print_depth if print-circle
12653 (print_object): Check for cycles even when print-circle is nil and

12716 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12717 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12718 (NEED_MEM_INSERT): New macro.
12719 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12720 Remove one incorrect comment and fix another.

12725 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12726 (r_alloc_sbrk): Now static.
12728 Improve ralloc.c interface checking.
12729 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12730 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

12756 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12757 * s/netbsd.h, s/sol2-6.h:
12758 Remove definition of GC_MARK_STACK, since the default now works.
12759 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12760 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12761 no longer the default.
12762 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12764 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12766 * lread.c (lisp_file_lexically_bound_p):

12789 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12790 against is gone. It's better to use vfork now so that when Cygwin
12791 gains a new, working vfork, we use it automatically (bug#10398).

12818 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12819 not just in the obarray, before snarfing them. (Bug#11036)
12821 * Makefile.in ($(leimdir)/leim-list.el):
12822 Pass EMACS rather than BUILT_EMACS.
12824 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12826 * process.c (make_process):
12827 * process.h: Add integer `gnutls_handshakes_tried' member to
12830 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12831 Add convenience `GNUTLS_LOG2i' macro.
12833 * gnutls.c (gnutls_log_function2i): Convenience log function.
12834 (emacs_gnutls_read): Use new log functions,
12835 `gnutls_handshakes_tried' process member, and
12836 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12837 attempts per process (connection).
12839 2012-04-09 Chong Yidong <cyd@gnu.org>
12841 * eval.c (Fuser_variable_p, user_variable_p_eh)
12842 (lisp_indirect_variable): Functions deleted.
12843 (Fdefvar): Caller changed.
12845 * callint.c (Finteractive, Fcall_interactively):
12846 * minibuf.c (Fread_variable): Callers changed.
12848 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12850 * xdisp.c (set_cursor_from_row): If the display string appears in
12851 the buffer at position that is closer to point than the position
12852 after the display string, display the cursor on the first glyph of
12853 the display string. Fixes cursor display when a 'display' text
12854 property immediately follows invisible text. (Bug#11094)
12856 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12858 composite.c: use 'double' consistently
12859 * composite.c (get_composition_id): Use 'double' consistently
12860 instead of converting 'float' to 'double' and vice versa; this is
12861 easier to understand and avoids a GCC warning.
12863 2012-04-09 Glenn Morris <rgm@gnu.org>
12865 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12866 preparation for dumping it with emacs. (Bug#4789)
12867 (leimdir): New variable.
12868 ($(leimdir)/leim-list.el): New rule.
12869 (emacs$(EXEEXT)): Depend on leim-list.el.
12871 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)

12887 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12888 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12889 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12890 objects, as mark_maybe_pointer will catch them otherwise.
12891 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12892 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12910 [!WINDOWSNT]: New macros.
12911 (init_libxml2_functions, libxml2_loaded_p): New functions.
12912 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12913 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12914 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12915 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12917 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12918 Call init_libxml2_functions before calling libxml2 functions.
12919 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12921 * emacs.c: Don't include libxml/parser.h.
12922 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12923 xmlCleanupParser directly.
12925 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12927 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12929 * indent.c (Fvertical_motion): If there is a display string at
12930 point, use it.vpos to compute how many lines to backtrack after
12931 move_it_to point. (Bug#11133)
12933 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12935 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12936 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12937 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12938 macros related to unification of CJK characters. For the details,
12939 see the discussion following the message here:
12940 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12942 2012-04-04 Chong Yidong <cyd@gnu.org>
12944 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12946 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12948 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12949 instead of alloca. (Bug#11138)
12951 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12953 * w32menu.c (is_simple_dialog): Properly check lisp types.
12956 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12958 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12959 position we get to after a call to move_it_to fails the
12960 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12961 only if we wind up in a string from display property. (Bug#11063)
12963 * window.c (Fdelete_other_windows_internal): Invalidate the row
12964 and column information about mouse highlight, so that redisplay
12965 restores it after reallocating the glyph matrices. (Bug#7464)
12967 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12968 string comes from a `display' text property, use the buffer
12969 position of that property as if we actually saw that position in
12971 (move_it_by_lines): Remove the assertion that
12972 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12973 violated when there's a before-string at the beginning of a line.
12976 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12978 * xdisp.c (append_space_for_newline): If the default face was
12979 remapped, use the remapped face for the appended newline.
12980 (extend_face_to_end_of_line): Use the remapped default face for
12981 extending the face to the end of the line.
12982 (display_line): Call extend_face_to_end_of_line when the default
12983 face was remapped. (Bug#11068)
12985 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12987 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12989 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12991 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12993 2012-03-27 Glenn Morris <rgm@gnu.org>
12995 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12998 2012-03-26 Kenichi Handa <handa@m17n.org>
13000 * dispextern.h (struct glyph): Fix previous change. Change the
13001 bit length of glyphless.ch to 25 (Bug#11082).
13003 2012-03-26 Chong Yidong <cyd@gnu.org>
13005 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13006 (command_loop_1): Use it; inhibit selection update for
13007 handle-select-window too (Bug#8996).
13009 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13011 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13013 2012-03-25 Kenichi Handa <handa@m17n.org>
13015 * dispextern.h (struct glyph): Change the bit length of
13016 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13018 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13020 * s/ms-w32.h (tzname): Include time.h before redirecting to
13021 _tzname. Fixes the MSVC build. (Bug#9960)
13023 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13025 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13028 * xterm.c (XTread_socket): Only modify handling_signal if
13029 !SYNC_INPUT. (Bug#11080)
13031 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13033 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13034 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13035 when fetching a multibyte character consumes more bytes than
13036 CHAR_BYTES returns, due to unification of CJK characters in
13037 string_char. (Bug#11073)
13039 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13041 * process.c (wait_reading_process_output): Handle pty disconnect
13042 by refraining from sending oneself a SIGCHLD (bug#10933).
13044 2012-03-22 Chong Yidong <cyd@gnu.org>

13049 Mark string as coming from a prefix property.
13050 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13051 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13053 2012-03-21 Chong Yidong <cyd@gnu.org>
13055 * xfaces.c (Vface_remapping_alist): Doc fix.
13057 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13059 * w32proc.c (Fw32_set_console_codepage)
13060 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13063 2012-03-20 Chong Yidong <cyd@gnu.org>
13065 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13066 to reflect default non-nil value of redisplay-dont-pause.
13068 2012-03-19 Kenichi Handa <handa@m17n.org>
13070 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13071 it fit in a valid range (Bug#11003).
13073 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13075 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13076 that is not from display property, accept the row as a "cursor
13077 row" if one of the string's character has a non-nil `cursor'
13078 property. Fixes cursor positioning when there are newlines in
13079 overlay strings, e.g. in icomplete.el. (Bug#11035)
13081 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13083 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13085 2012-03-12 Chong Yidong <cyd@gnu.org>
13087 * eval.c (inhibit_lisp_code): Rename from
13088 inhibit_window_configuration_change_hook; move from window.c.
13090 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13091 * window.c (run_window_configuration_change_hook)
13092 (syms_of_window): Callers changed.
13094 2012-03-11 Chong Yidong <cyd@gnu.org>
13096 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13098 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13100 2012-03-10 Chong Yidong <cyd@gnu.org>
13102 * frame.c (other_visible_frames): Don't assume the selected frame
13103 is visible (Bug#10955).
13105 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13107 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

13111 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13112 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13115 2012-03-03 Glenn Morris <rgm@gnu.org>
13117 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13119 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13121 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13122 position past the first glyph_row that ends at ZV. (Bug#10902)
13123 (redisplay_window, next_element_from_string): Fix typos in
13125 (redisplay_window): Pass to move_it_vertically the margin in
13126 pixels, not in screen lines.
13128 2012-03-02 Glenn Morris <rgm@gnu.org>
13130 * buffer.c (buffer-list-update-hook): Doc fix.
13132 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13134 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13135 push_it before setting up the iterator for the first overlay
13136 string, even if we have an empty string loaded.
13137 (next_overlay_string): If there's an empty string on the iterator
13138 stack, pop the stack. (Bug#10903)
13140 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13142 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13143 Suggested by Stefan Monnier in
13144 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13145 * alloc.c (widen_to_Lisp_Object): New static function.
13146 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13147 and widening them to Lisp_Objects. This would work even if
13148 USE_LSB_TAG is defined and wide integers are used, which might
13149 happen in a future version of Emacs.
13151 2012-02-25 Chong Yidong <cyd@gnu.org>
13153 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13156 * xselect.c (Fx_selection_exists_p): Doc fix.
13157 (x_clipboard_manager_save_all): Print an informative message
13158 before saving to clipboard manager.
13160 2012-02-24 Chong Yidong <cyd@gnu.org>
13162 * keyboard.c (process_special_events): Handle all X selection
13163 requests in kbd_buffer, not just the next one (Bug#8869).
13165 2012-02-23 Chong Yidong <cyd@gnu.org>
13167 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13168 call when setting menu-bar-lines and tool-bar-lines parameters.
13169 (unwind_create_frame_1): New helper function.
13171 * window.c (inhibit_window_configuration_change_hook): New var.
13172 (run_window_configuration_change_hook): Obey it.

13190 when computing $valmask.
13192 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13193 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13194 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13195 It's useless in that case, and it can cause problems on hosts
13196 that allocate halves of EMACS_INT values separately.
13197 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13198 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13199 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13200 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13201 it avoids undefined behavior on hosts where shifting right by more
13202 than the word width has undefined behavior.
13204 2012-02-19 Chong Yidong <cyd@gnu.org>
13206 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13207 (Funhandled_file_name_directory, Ffile_name_as_directory)
13208 (Fdirectory_file_name, Fexpand_file_name)
13209 (Fsubstitute_in_file_name): Protect against invalid file handler
13210 return values (Bug#10845).
13212 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13214 * .gdbinit (pitx): Fix incorrect references to fields of the
13217 2012-02-17 Chong Yidong <cyd@gnu.org>

13221 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13223 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13224 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13226 2012-02-15 Chong Yidong <cyd@gnu.org>
13228 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13229 marked as special. Also, starting docstrings with * is obsolete.
13231 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13233 * gnutls.c (emacs_gnutls_write): Fix last change.

13242 * keymap.c (Fsingle_key_description): Handle char ranges.
13244 2012-02-12 Chong Yidong <cyd@gnu.org>
13246 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13247 as that creates a dangerous corner case.
13249 * window.c (Fdelete_window_internal): Invalidate the mouse
13250 highlight (Bug#9904).
13252 2012-02-12 Glenn Morris <rgm@gnu.org>
13254 * xselect.c (Fx_own_selection_internal)
13255 (Fx_get_selection_internal, Fx_disown_selection_internal)
13256 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13257 * nsselect.m (Fx_own_selection_internal)
13258 (Fx_disown_selection_internal, Fx_selection_exists_p)
13259 (Fx_selection_owner_p, Fx_get_selection_internal):
13260 Sync docs and argument specs with the xselect.c versions.
13262 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13264 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13266 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13268 * w32select.c (Fx_selection_exists_p): Sync doc string and
13269 argument list with xselect.c. (Bug#10783)
13271 * w16select.c (Fx_selection_exists_p): Sync doc string and
13272 argument list with xselect.c. (Bug#10783)

13280 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13282 2012-02-07 Chong Yidong <cyd@gnu.org>
13284 * buffer.c (Fbuffer_local_variables)
13285 (buffer_lisp_local_variables): Handle unbound vars correctly;
13286 don't let Qunbound leak into Lisp.
13288 2012-02-07 Glenn Morris <rgm@gnu.org>
13290 * image.c (Fimagemagick_types): Doc fix.
13292 * image.c (imagemagick-render-type): Change it from a lisp object
13293 to an integer. Move the doc here from the lisp manual.

13807 * fileio.c (Finsert_file_contents): Move after-change-function call
13808 to before the "handled:" label, since all "goto handled" appear in
13809 cases where the *-change-functions have already been properly called
13812 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
13814 * keyboard.c (interrupt_signal): Don't call kill-emacs when

13819 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13820 verifies glyph row's hash code--we have just reallocated the
13821 glyphs, so their contents can be complete garbage. (Bug#10164)

13867 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13868 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13869 this macro definition.

13899 visible and out of scroll-margin. (Bug#10105)
13900 (start_display): Don't move to the next line if the display should
13901 start at a newline that is part of a display vector or an overlay

13982 Otherwise, valgrind does not work on some platforms.
13983 Problem reported by Andreas Schwab in
13984 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13985 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13986 is set, removing the need for VIRT_ADDRESS_VARIES.
13987 (PURE_P): Use a more-efficient implementation that needs just one
13988 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13989 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13990 to 4 (xorl, subq, cmpq, setbe).
13991 * alloc.c (pure): Always extern now, since that's the

13993 (PURE_POINTER_P): Use a single comparison, not two, for
13994 consistency with the new puresize.h.
13995 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13996 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14002 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14003 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14004 behave as if the cursor position were at the window margin.
14006 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14007 and the cursor position is out of bounds, behave as if the cursor
14008 position were at the window margin. (Bug#10075)
14010 2011-11-18 Chong Yidong <cyd@gnu.org>
14012 * window.c (Fwindow_combination_limit): Make first argument

14031 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14033 * xdisp.c (row_hash): New function, body extracted from
14034 compute_line_metrics.
14035 (compute_line_metrics): Call row_hash, instead of computing the
14038 * dispnew.c (verify_row_hash): Call row_hash for computing the
14039 hash code of a row, instead of duplicating code from xdisp.c.
14041 * dispextern.h (row_hash): Add prototype.
14043 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14045 * frame.c (delete_frame): Don't delete the terminal when the last

14079 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14081 * xdisp.c (display_line): Move the call to
14082 highlight_trailing_whitespace before the call to
14083 compute_line_metrics, since the latter needs to see the final
14084 faces of all the glyphs to compute ROW's hash value.
14085 Fixes assertion violations in row_equal_p. (Bug#10035)
14087 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14089 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

14094 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14095 with user-defined heap size. Bump the default size of the temacs
14096 heap to 27MB, to avoid memory warning when running temacs.

14099 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14100 current_matrix and desired_matrix. (Bug#9990)
14101 (verify_row_hash) [XASSERTS]: New function.

14146 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14148 Avoid some portability problems by eschewing 'extern inline' functions.
14149 The trivial performance wins aren't worth the portability hassles; see
14150 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14152 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14153 (window_box_width, window_box_left, window_box_left_offset)
14154 (window_box_right, window_box_right_offset): Undo previous change,
14155 by removing the "extern"s.
14156 * intervals.c (adjust_intervals_for_insertion)
14157 (adjust_intervals_for_deletion): Undo previous change,
14158 making these static again.

14226 (window_box_width, window_box_left, window_box_left_offset)
14227 (window_box_right, window_box_right_offset): Declare extern.
14228 Otherwise, these inline functions do not conform to C99 and
14229 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14230 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14231 * intervals.c (adjust_intervals_for_insertion)

14234 (static_offset_intervals): Remove.
14235 (offset_intervals): Rewrite using the old contents of
14236 static_offset_intervals. The old version didn't conform to C99
14237 because an extern inline function contained a reference to an
14238 identifier with static linkage.

14490 * process.c (make_process): Set gnutls_state to NULL.

14542 (bidi_resolve_weak): Don't enter the expensive loop if the current
14543 position is before next_en_pos. Record the bidi type of the first
14544 non-ET, non-BN character we find, in addition to its position.
14545 (bidi_level_of_next_char): Invalidate next_en_type when
14546 next_en_pos is over-stepped.
14548 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14550 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14551 * editfns.c: Rewrite current-time-zone so that it invokes
14552 the equivalent of (format-time-string "%Z") to get the time zone name.
14553 This fixes a bug when the time zone name contains characters that
14554 need converting from the system time locale to Emacs internal format.
14555 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14556 that patch fixed format-time-string to do the conversion, but
14557 I forgot to fix current-time-zone.
14558 (format_time_string): New function, containing most of
14559 what Fformat_time_string used to contain.
14560 (Fformat_time_string): Rewrite in terms of format_time_string.
14561 This doesn't change this function's behavior.
14562 (current-time-zone): Rewrite to use format_time_string.
14563 This fixes the bug reported by Michael Schierl in
14564 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14565 Jason Rumney's 2007-06-07 change worked around this bug, but
14567 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14569 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14571 * xdisp.c (start_display): If the character at POS is displayed
14572 via a display vector, reset IT->current.dpvec_index to zero.
14573 (try_window_reusing_current_matrix): If a line ends in a display
14574 vector or the next line starts in a display vector, continue
14575 redrawing the window even though the character position of
14576 start_row was reached.
14579 2011-10-18 Chong Yidong <cyd@gnu.org>
14581 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14582 with nobreak-char-display too.
14584 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14586 Fix part 3 of bug#9771.
14587 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14588 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14589 non-neutral characters if the current character is a paragraph
14590 separator (a.k.a. Newline). This avoids running the same
14591 expensive loop twice, once when we consume the preceding newline
14592 and the other time when the line actually needs to be displayed.
14593 Avoid the loop when we see neutrals on the base embedding level
14594 following a character whose directionality is the same as the
14595 paragraph's. This avoids running the expensive loop when a line
14596 ends in a long sequence of neutrals, like control characters.
14597 Add assertion against STRONG_AL type. Slightly rearrange code
14598 that determines the type of a neutral given the first non-neutral
14600 (bidi_level_of_next_char): Set next_en_pos to zero when
14601 invalidating its info.
14603 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14605 * xdisp.c (push_display_prop): Determine whether to record string
14606 or buffer position by IT->string, not by IT->method. Allow
14607 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14608 (move_it_vertically_backward): Don't look for character position
14609 immediately after the newline when in a continuation line.
14612 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14614 * window.c (coordinates_in_window): Rewrite and delabelize
14615 vertical border check. (Bug#5357) (Bug#9618)

14625 avoid crash when xmalloc overrun checking is enabled.
14627 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14629 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14630 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14631 cursor motion with <left> and <right> arrow keys.
14633 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14634 some callers set that themselves.
14636 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14638 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14639 display string and the previous row comes from the same string and
14640 is empty. (Bug#9739) (Bug#9738)
14642 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14644 * doc.c (get_doc_string): Encode file name (bug#9735).
14646 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14648 * bidi.c (bidi_level_of_next_char):
14649 * xdisp.c (get_visually_first_element): Remove old incorrect
14650 comments regarding the Unicode Line Separator character.
14652 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

14663 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14665 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14666 Some packages use them to denote characters with modifiers.
14668 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14670 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14671 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14672 matching a pp-number. Rename parameter var to var1.

14691 presence of header-line. (Bug#4426)
14693 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14695 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14696 Don't advertise functionality which we discourage or doesn't work.
14698 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14700 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14701 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14702 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14703 this makes Emacs dump core during garbage collection on rare
14704 occasions. sizeof is obviously inferior to offsetof here, so
14705 stick with offsetof.
14706 (GC_POINTER_ALIGNMENT): New macro.
14707 (mark_memory): Omit 3rd (offset) arg; caller changed.
14708 Don't assume EMACS_INT alignment is the same as pointer alignment.
14710 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14712 * keyboard.c (read_key_sequence_remapped): New var.
14713 (read_key_sequence): Compute remapping in the right buffer.
14714 (command_loop_1): Use read_key_sequence's remapping directly.
14716 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14718 * dired.c (file_name_completion): Don't expand file name.
14719 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14720 before checking file name handler.
14722 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14723 they've been requested explicitly (bug#9591).
14725 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14727 * keymap.c (Fsingle_key_description): Use make_specified_string
14728 instead of build_string to build string from push_key_description.
14731 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14733 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14734 This fixes a Y2038 bug on 64-bit hosts.
14735 * buffer.c (reset_buffer):
14736 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14737 (Fclear_buffer_auto_save_failure):
14738 Use 0, not -1, to represent an unset failure time, since time_t
14739 might not be signed.
14741 Remove dependency on glibc malloc internals.
14742 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14743 Move back here from lisp.h, but with their new implementations.
14744 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14745 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14746 * charset.c (charset_table_init): New static var.
14747 (syms_of_charset): Use it instead of xmalloc. This removes a
14748 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14749 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14750 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14751 Move back to alloc.c.
14752 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14753 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14755 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14757 * nsterm.m (windowDidResize): Call x_set_window_size only when
14758 ns_in_resize is true. Otherwise set pixelwidth/height and
14759 call change_frame_size (Bug#9628).
14761 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14763 Port --enable-checking=all to Fedora 14 x86-64.
14764 * charset.c (syms_of_charset): Also account for glibc malloc's
14765 internal overhead when calculating the initial malloc maximum.
14767 Port --enable-checking=all to Fedora 14 x86.
14768 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14770 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14771 (overrun_check_realloc, overrun_check_free):
14772 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14773 That way, xmalloc returns a properly-aligned pointer even if
14774 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14775 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14776 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14777 into account when calculating the initial malloc maximum.
14778 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14779 Move here from alloc.c, so that charset.c can use it too.
14780 Properly align; the old code wasn't right for common 32-bit hosts
14781 when configured with --enable-checking=all.
14782 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14783 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14785 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14787 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14790 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14792 * xdisp.c (compute_display_string_end): If there's no display
14793 string at CHARPOS, return -1.
14795 * bidi.c (bidi_fetch_char): When compute_display_string_end
14796 returns a negative value, treat the character as a normal
14797 character not covered by a display string. (Bug#9624)
14799 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14801 * lread.c (Fread_from_string): Fix typo in docstring.
14803 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14805 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14806 newline, reseat the iterator instead of bidi-iterating there one
14807 character at a time. (Bug#9610)
14808 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14809 TO_CHARPOS if the bidi iterator is at base embedding level.
14811 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14813 * lread.c (readevalloop): Use correct code for NBSP.
14814 (read1): Likewise. (Bug#9608)
14816 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14818 * dbusbind.c (Fdbus_register_signal): When service is not
14819 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14821 2011-09-25 Glenn Morris <rgm@gnu.org>
14823 * buffer.c (truncate-lines): Doc fix.
14825 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14827 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14828 (Fset_window_next_buffers): Doc fix.
14830 2011-09-24 Glenn Morris <rgm@gnu.org>
14832 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14834 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14836 Fix minor problems found by static checking.
14837 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14838 * indent.c (Fvertical_motion): Fix == vs = typo.
14840 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14842 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14843 Default value is now t. Doc fix.
14845 * indent.c (Fvertical_motion): Compute and apply the overshoot
14846 logic when moving up, not only when moving down. Fix the
14847 confusing name and values of the it_overshoot_expected variable;
14848 logic changes accordingly. (Bug#9254) (Bug#9549)
14850 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14851 CHARPOS is covered by a display string which includes newlines.
14852 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14853 is covered by a display string with embedded newlines.
14855 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14857 * dbusbind.c (Fdbus_register_signal): Add match rule to
14858 Vdbus_registered_objects_table. (Bug#9581)
14859 (Fdbus_register_method, Vdbus_registered_objects_table):
14862 2011-09-24 Jim Meyering <meyering@redhat.com>
14864 do not ignore write error for any output size
14865 The previous change was incomplete.
14866 While it makes emacs --batch detect the vast majority of stdout
14867 write failures, errors were still ignored whenever the output size is
14868 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14869 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14870 && echo FAIL: ignored write error
14871 FAIL: ignored write error
14872 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14873 && echo FAIL: ignored write error
14874 FAIL: ignored write error
14875 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14877 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14879 * emacs.c (Fkill_emacs): In noninteractive mode exit
14880 non-successfully if a write error occurred on stdout. (Bug#9574)
14882 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14884 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14887 * dispextern.h (struct it): Update the comment documenting what
14890 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14892 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14893 a display string, extend search for cursor position to end of row.
14894 (find_row_edges): If the row ends in a newline from a display
14895 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14896 Handle the case of a display string with multiple newlines.
14897 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14898 non-empty line. Fixes confusing cursor motion with arrow keys at
14899 the beginning of a line that starts with whitespace.
14901 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14903 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14906 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14908 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14909 boolean (Bug#9154).
14911 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14913 * xdisp.c (display_line): Record maximum and minimum buffer
14914 positions even if no glyphs were produced (e.g., by a zero-width
14915 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14916 buffer positions that will be removed from the glyph row because
14918 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14919 column is beyond frame width: don't subtract 1 "pixel" when
14920 computing width of the stretch.
14921 (reseat_at_next_visible_line_start): Undo the change made on
14922 2011-09-17 that saved paragraph information and restored it after
14923 the call to `reseat'. (Bug#9545)
14925 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14927 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14928 and turn window cursor on if cleared (Bug#9415).
14930 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14932 * search.c (boyer_moore): Take unibyte characters from pattern
14933 literally. (Bug#9458)
14935 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14937 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14939 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14941 Fix minor problem found by static checking.
14942 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14943 initialized, to pacify gcc -Wuninitialized.
14945 * fileio.c: Report proper errno when syscall falls.
14946 (Finsert_file_contents): Save and restore errno,
14947 so that report_file_error outputs the correct diagnostic.
14948 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14950 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14952 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14954 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14956 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14957 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14959 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14961 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14962 about the current paragraph and restore it after the call to reseat.
14964 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14965 (bidi_find_paragraph_start): Search back for paragraph beginning
14966 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14967 (bidi_move_to_visually_next): Only trigger paragraph-related
14968 computations when the last character is a newline or at EOB, not
14969 just any NEUTRAL_B. (Bug#9470)
14971 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14972 truncated lines if point is covered by a display string. (Bug#9524)
14974 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14976 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14977 (cons_to_x_long): New function.
14978 (lisp_data_to_selection_data): Use it. Correct the test for
14979 short-versus-long data; it was negated. Break out of vector
14980 loop, for efficiency, when a long datum is discovered.
14982 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14984 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14986 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14988 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14989 GCC PR/17406) by declaring this function with external scope.
14991 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14993 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14994 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14996 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14998 * editfns.c (Fformat): Correctly handle text properties on "%%".
15000 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15002 * xterm.c (x_draw_composite_glyph_string_foreground):

15004 * term.c (encode_terminal_code):
15005 * composite.c (composition_update_it, get_composition_id):
15006 * xdisp.c (get_next_display_element)
15007 (fill_composite_glyph_string): Add comments about special meaning
15008 of TAB characters in a composition.
15010 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15012 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15013 This occurs when processing a multibyte format.
15014 Problem reported by Wolfgang Jenker.
15016 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15018 * xdisp.c (try_cursor_movement): Only check for exact match if
15019 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15021 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15023 Remove unused external symbols.
15024 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15025 * xdisp.c (calc_pixel_width_or_height): Now static.
15026 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15027 * indent.c (check_display_width):
15028 * w32term.c: Fix comment to match code.
15029 * xterm.c, xterm.h (x_catching_errors): Remove.
15031 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15033 * xselect.c: Use signed conversions more consistently (Bug#9498).
15034 (selection_data_to_lisp_data): Assume incoming selection data are
15035 signed integers, not unsigned. This is to be consistent with
15036 outgoing selection data, which was modified to use signed integers
15037 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15038 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15039 expects long, not unsigned long.
15041 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15043 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15044 computation of loop end. Reported by Johan Bockgård
15047 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15049 * frame.c (Fother_visible_frames_p): Function deleted.
15051 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15053 * indent.c (compute_motion): Process display vector front to back
15054 rather than the other way around. (Bug#2496)
15056 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15058 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15060 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15062 * minibuf.c (Fread_from_minibuffer): Doc fix.
15064 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15066 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15067 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15069 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15071 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15072 value for non-existent files.
15074 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15076 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15077 set its "size" to -1. This will set the modtime_size field of
15078 the corresponding buffer to -1, which is what
15079 verify-visited-file-modtime expects for files that do not exist.
15082 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15084 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15086 * lisp.h: ... from here. push_key_description is no longer
15087 defined in keyboard.c, so its declaration should not be in
15088 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15089 logically belongs with push_key_description.
15091 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15093 * buffer.h: Include <sys/types.h> instead of <time.h>.
15094 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15095 Problem reported by Herbert J. Skuhra.
15097 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15099 * xml.c (parse_region): Make the parsing work for
15100 non-comment-starting XML files again (bug#9144).
15102 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15104 * image.c (gif_load): Fix calculation of bottom and right corner.
15107 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15109 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15110 redisplay in small windows.
15112 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15114 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15116 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15118 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15119 Operate on live windows only.
15121 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15123 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15125 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15127 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15128 only under bidi iteration.
15130 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15132 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15134 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15136 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15137 Without this fix, the command to link temacs failed due to an
15138 undefined symbol __builtin_isnan. This is because
15139 /usr/include/iso/math_c99.h #defines isnan(x) to
15140 __builtin_isnan(x), but the bundled gcc, which identifies itself
15141 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15143 * floatfns.c (isnan): #undef, and then #define to a clone of
15145 (Fisnan): Always define, since it's always available now.
15146 (syms_of_floatfns): Always define isnan at the Lisp level.
15148 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15150 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15152 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15154 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15155 The previous code assumed that file offsets (off_t values) fit in
15156 EMACS_INT variables, which is not true on typical 32-bit hosts.
15157 The code messed up by falsely reporting buffer overflow in cases
15158 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15159 when "big" contains more than 2**29 bytes, even though this
15160 inserts just one byte and does not overflow the buffer.
15161 (Finsert_file_contents): Store file offsets as off_t
15162 values, not as EMACS_INT values. Check for overflow when
15163 converting between EMACS_INT and off_t. When checking for
15164 buffer overflow or for overlap, take the offsets into account.
15165 Don't use EMACS_INT for small values where int suffices.
15166 When checking for overlap, fix a typo: ZV was used where
15167 ZV_BYTE was intended.
15168 (Fwrite_region): Don't assume off_t fits into 'long'.
15169 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15171 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15173 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15175 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15177 sprintf-related integer and memory overflow issues (Bug#9412).
15179 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15180 (esprintf, exprintf, evxprintf): New functions.
15181 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15182 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15183 (modify_event_symbol): Do not assume that the length of
15184 name_alist_or_stem is safe to alloca and fits in int.
15185 (Fexecute_extended_command): Likewise for function name and binding.
15186 (Frecursion_depth): Wrap around reliably on integer overflow.
15187 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15188 since some callers pass EMACS_INT values.
15189 (Fsingle_key_description): Don't crash if symbol name contains more
15190 than MAX_ALLOCA bytes.
15191 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15192 (get_minibuffer): Arg is now EMACS_INT, not int.
15193 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15194 (esprintf, exprintf, evxprintf): New decls.
15195 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15197 * dbusbind.c (signature_cat): New function.
15198 (xd_signature, Fdbus_register_signal):
15199 Do not overrun buffer; instead, report string overflow.
15201 * dispnew.c (add_window_display_history): Don't overrun buffer.
15202 Truncate instead; this is OK since it's just a log.
15204 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15205 even if the time zone offset is outlandishly large.
15206 Don't mishandle offset == INT_MIN.
15208 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15209 when creating daemon; the previous buffer-overflow check was incorrect.
15211 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15212 which has the guts of the old verror function.
15214 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15215 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15217 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15218 (font_unparse_xlfd): Don't blindly alloca long strings.
15219 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15220 fits in int, when using sprintf. Use single snprintf to count
15221 length of string rather than counting it via multiple sprintfs;
15222 that's simpler and more reliable.
15223 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15224 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15225 sprintf, in case result does not fit in int.
15227 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15228 (fontset_from_font): Print it.
15230 * frame.c (tty_frame_count): Now printmax_t, not int.
15231 (make_terminal_frame, set_term_frame_name): Print it.
15232 (x_report_frame_params): In X, window IDs are unsigned long,
15233 not signed long, so print them as unsigned.
15234 (validate_x_resource_name): Check for implausibly long names,
15235 and don't assume name length fits in 'int'.
15236 (x_get_resource_string): Don't blindly alloca invocation name;
15237 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15240 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15241 (xg_check_special_colors, xg_set_geometry):
15242 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15244 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15245 Use esprintf, not sprintf, in case result does not fit in int.
15247 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15248 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15249 it as a large positive number.
15250 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15251 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15253 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15254 in case result does not fit in int.
15256 * print.c (float_to_string): Detect width overflow more reliably.
15257 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15258 buffer overrun. Don't assume list length fits in 'int'. Treat
15259 print length of 0 as 0, not as infinity; to be consistent with other
15260 uses of print length in this function. Don't overflow print length
15261 index. Don't assume hash table size fits in 'long', or that
15262 vectorlike size fits in 'unsigned long'.
15264 * process.c (make_process): Use printmax_t, not int, to format
15265 process-name gensyms.
15267 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15269 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15270 to avoid potential buffer overrun.
15272 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15273 if X resource line is longer than 512 bytes.
15275 * xfns.c (x_window): Make sprintf buffer a bit bigger
15276 to avoid potential buffer overrun.
15278 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15280 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15282 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15284 Integer overflow fixes for scrolling, etc.
15285 Without these, Emacs silently mishandles large integers sometimes.
15286 For example, "C-u 4294967297 M-x recenter" was treated as if
15287 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15289 * xdisp.c (try_window_id): Check Emacs fixnum range before
15290 converting to 'int'.
15292 * window.c (window_scroll_line_based, Frecenter):
15293 Check that an Emacs fixnum is in range before assigning it to 'int'.
15294 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15295 values converted from Emacs fixnums.
15296 (Frecenter): Don't wrap around a line count if it is out of 'int'
15297 range; instead, treat it as an extreme value.
15298 (Fset_window_configuration, compare_window_configurations):
15299 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15301 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15302 that can exceed INT_MAX. Check that EMACS_INT value is in range
15303 before assigning it to the (possibly-narrower) index.
15304 (match_limit): Don't assume that a fixnum can fit in 'int'.
15306 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15309 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15310 (Fvertical_motion): Don't wrap around LINES values that don't fit
15311 in 'int'. Instead, treat them as extreme values. This is good
15312 enough for windows, which can't have more than INT_MAX lines anyway.
15314 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15316 * Require libxml/parser.h to avoid compilation warning.
15318 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15320 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15321 since this reportedly can destroy thread storage.
15323 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15325 * syntax.c (find_defun_start): Update all cache variables if
15326 exiting early (Bug#9401).
15328 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15330 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15332 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15333 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15334 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15336 * term.c (tty_append_glyph): New function.
15337 (produce_stretch_glyph): Static function and its prototype deleted.
15339 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15342 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15344 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15345 when checking :margin (Bug#9390).
15346 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15347 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15348 so that the name doesn't mislead. All uses changed.
15350 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15352 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15355 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15357 * xdisp.c (move_it_to): Don't bail out early when reaching
15358 position beyond to_charpos, if we are scanning backwards.
15359 (move_it_vertically_backward): When DY == 0, make sure we get to
15360 the first character in the line after the newline.
15362 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15364 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15365 (ccl_driver): Do not generate an out-of-range pointer.
15366 (Fccl_execute_on_string): Remove unnecessary check for
15367 integer overflow, noted by Stefan Monnier in
15368 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15369 Remove a FIXME that didn't need fixing.
15370 Simplify the newly-introduced buffer reallocation code.
15372 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15374 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15376 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15378 Integer and memory overflow issues (Bug#9196).
15380 * doc.c (get_doc_string): Rework so that
15381 get_doc_string_buffer_size is the actual buffer size, rather than
15382 being 1 less than the actual buffer size; this makes xpalloc more
15385 * image.c (x_allocate_bitmap_record, cache_image):
15386 * xselect.c (Fx_register_dnd_atom):
15387 Simplify previous changes by using xpalloc.
15389 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15390 since either will do and ptrdiff_t is convenient with xpalloc.
15392 * charset.c (charset_table_size)
15393 (struct charset_sort_data.priority): Now ptrdiff_t.
15394 (charset_compare): Don't overflow if priorities differ greatly.
15395 (Fsort_charsets): Don't assume list length fits in int.
15396 Check for size-calculation overflow when allocating sort data.
15397 (syms_of_charset): Allocate an initial charset table that is
15398 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15400 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15402 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15403 The actual value is always <= INT_MAX, and leaving it unsigned made
15404 overflow checking harder.
15406 * dispextern.h (struct glyph_matrix.rows_allocated)
15407 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15408 with xpalloc. The values are still always <= INT_MAX.
15410 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15412 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15413 (SAFE_NALLOCA): New macro.
15415 * region-cache.c (struct boundary.pos, find_cache_boundary)
15416 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15417 (set_cache_region, invalidate_region_cache)
15418 (revalidate_region_cache, know_region_cache, region_cache_forward)
15419 (region_cache_backward, pp_cache):
15420 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15421 so that ptrdiff_t * can be passed to xpalloc.
15422 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15423 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15424 (pp_cache): Don't assume cache_len fits in int.
15425 * region-cache.h: Adjust extern decls to match.
15427 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15428 EMACS_INT, since either will do, for xpalloc.
15430 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15431 (xnmalloc, xnrealloc, xpalloc): New functions.
15433 * bidi.c (bidi_shelve_header_size): New constant.
15434 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15435 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15437 * bidi.c (bidi_cache_shrink):
15438 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15440 Don't update size of array until after memory allocation succeeds,
15441 because xmalloc/xrealloc may not return.
15442 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15443 now that we have proper integer overflow checking.
15444 (record_overlay_string, overlay_strings): Catch overflows when
15445 calculating size of overlay_str_buf.
15447 * callproc.c (Fcall_process): Check for size overflow when
15448 calculating size of args2.
15449 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15450 Normally we prefer signed values, but sticking with ptrdiff_t would
15451 require adding more-complicated checks.
15453 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15454 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15455 Redo buffer-overflow calculations to avoid integer overflow.
15456 Add a FIXME comment where memory seems to be over-allocated.
15458 * character.c (Fstring): Check for size-calculation overflow.
15460 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15461 unnecessary integer overflow. Check for size overflow.
15462 (encode_coding_object): Don't update size until xmalloc succeeds.
15464 * composite.c (get_composition_id): Check for overflow in glyph
15465 length calculations.
15467 Integer and memory overflow fixes for display code.
15468 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15469 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15470 (scrolling_window): Check for overflow in size calculations.
15471 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15472 Don't assume glyph table len fits in int.

15474 (row_table_size): Now ptrdiff_t, not int.
15475 (scrolling_window): Avoid overflow in size calculations.
15476 Don't update size until allocation succeeds.
15477 * fns.c (concat): Check for overflow in size calculations.
15478 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15479 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15480 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15482 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15483 (get_doc_string): Check for size calculation overflow.
15484 Don't update size until allocation succeeds.
15485 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15486 EMACS_INT, where ptrdiff_t will do.
15487 (Fsubstitute_command_keys): Check for string overflow.
15489 * editfns.c (set_time_zone_rule): Don't assume environment length
15491 (message_length): Now ptrdiff_t, not int.
15492 (Fmessage_box): Don't update size until allocation succeeds.
15493 Don't assume message length fits in int.
15494 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15496 * emacs.c (main): Do not reallocate argv, since there is a null at
15497 the end that can be overwritten, and this way there's no need to
15498 worry about size-calculation overflow.
15499 (sort_args): Check for size-calculation overflow.
15501 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15503 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15505 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15506 (x_set_scroll_bar_width, x_figure_window_size):
15507 Check for integer overflow.
15508 (x_set_alpha): Do not assume XINT fits in int.
15510 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15511 This is for the members text_lines, text_cols, total_lines, total_cols,
15512 where the system imposes an 'int' limit.
15514 * fringe.c (Fdefine_fringe_bitmap):
15515 Don't update size until alloc works.
15517 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15518 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15520 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15521 Check for size-calculation overflow.
15522 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15523 do, as we prefer signed integers.
15524 (id_to_widget.max_size, id_to_widget.used)
15525 (xg_store_widget_in_map, xg_remove_widget_from_map)
15526 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15527 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15528 Use and return ptrdiff_t, not int.
15529 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15530 * gtkutil.h: Change prototypes to match the above.
15532 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15533 are duplicate now that they've been promoted to lisp.h.
15534 (x_allocate_bitmap_record, x_alloc_image_color)
15535 (make_image_cache, cache_image, xpm_load):
15536 Don't update size until alloc is done.
15537 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15539 Check for size calculation overflow.
15540 (ct_colors_allocated_max): New constant.
15541 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15544 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15545 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15546 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15547 Use ptrdiff_t, not int, to count maps.
15548 (read_char_minibuf_menu_prompt): Check for overflow in size
15549 calculations. Don't update size until allocation succeeds.
15550 Redo calculations to avoid overflow.
15551 * keyboard.h: Change prototypes to match the above.
15553 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15555 (current_minor_maps): Check for size calculation overflow.
15556 * keymap.h: Change prototypes to match the above.
15558 * lread.c (read1, init_obarray): Don't update size until alloc done.
15560 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15561 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15563 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15564 Now ptrdiff_t, not int.
15565 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15569 in size calculation.
15571 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15573 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15574 overflow. Don't bother calling xmalloc when xrealloc will do.

15579 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15580 for command line length. Do not attempt to address one before the
15581 beginning of an array, as that's not portable.
15583 * term.c (max_frame_lines): Remove; unused.
15584 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15586 (encode_terminal_code, calculate_costs): Check for size
15587 calculation overflow.
15588 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

15591 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15593 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15594 subtracting pointers.
15595 (gobble_line): Check for overflow more carefully. Don't update size
15598 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15599 Don't update size until alloc done.
15600 Redo size calculations to avoid overflow.
15601 Check for size calculation overflow.
15602 (main) [DEBUG]: Fix typo in invoking tparam1.

15609 Use ptrdiff_t, not int, for sizes.
15610 (Finternal_make_lisp_face, cache_face):
15611 Check for size calculation overflow.
15612 (cache_face): Treat size calculation overflows as if they were
15613 memory exhaustion (the usual treatment), rather than aborting.
15615 * xfns.c (x_encode_text, x_set_name_internal)
15616 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15617 sizes, since they can exceed INT_MAX in size. Check for size
15618 calculation overflow.
15620 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15621 (xg_select): Check for size calculation overflow.
15622 Don't update size until alloc done.
15624 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15625 as sprintf is limited to int lengths.
15627 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15628 (X_LONG_MIN): New macros.
15629 Use them to make the following changes clearer.
15630 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15631 This change doesn't affect the value now, but it may help remind
15632 future maintainers not to raise the value too much later.
15633 (SELECTION_QUANTUM): Remove, replacing with ...
15634 (selection_quantum): ... new function, which avoids overflow.
15636 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15637 assumption that selection length fits in 'int'.
15638 (x_reply_selection_request, x_handle_selection_request)
15639 (x_get_window_property, receive_incremental_selection)
15640 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15641 (lisp_data_to_selection_data, clean_local_selection_data):

15643 (x_reply_selection_request, x_get_window_property)
15644 (receive_incremental_selection, x_property_data_to_lisp):
15645 Redo calculations to avoid overflow.
15646 (x_reply_selection_request): When sending hint, ceiling it at
15647 X_LONG_MAX rather than relying on wraparound overflow to send
15649 (x_get_window_property, receive_incremental_selection)
15650 (lisp_data_to_selection_data, x_property_data_to_lisp):
15651 Check for size-calculation overflow.
15652 (x_get_window_property, receive_incremental_selection)

15654 Don't store size until memory allocation succeeds.
15655 (x_get_window_property): Plug memory leak on memory exhaustion.
15656 Don't double-block input; malloc is safe here. Don't assume 2**34
15657 - 4 fits in unsigned long. Add an xassert to check
15658 XGetWindowProperty overflow. Be more careful about overflow
15659 calculations, and distinguish size from memory overflow better.
15660 (receive_incremental_selection): When tracing, don't assume
15661 unsigned int is less than INT_MAX.
15662 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15663 harmful) conversions of unsigned short to int.
15664 (lisp_data_to_selection_data): Don't assume that integers
15665 in the range -65535 through -1 fit in an X unsigned short.
15666 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15667 result parameters unless successful. Rely on cons_to_unsigned
15668 to report problems with elements; the old code wasn't right anyway.
15669 (x_check_property_data): Check for int overflow; we cannot use
15670 a wider type due to X limits.
15671 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15673 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15675 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15676 (x_term_init): Check for size calculation overflow.
15677 (x_color_cells): Don't store size until memory allocation succeeds.
15678 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15679 Don't assume alloca size is less than MAX_ALLOCA.
15680 (x_term_init): Don't assume length fits in int (sprintf is limited
15683 Use ptrdiff_t for composition IDs.

15702 * image.c (xpm_get_color_table_h):
15703 * lisp.h (hash_lookup, hash_put):
15704 * minibuf.c (Ftest_completion):
15705 Use ptrdiff_t for hash table indexes, not int (which is too
15706 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15707 32-bit --with-wide-int hosts).
15709 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15710 Add a FIXME comment about memory leaks.
15711 (syms_of_charset): Don't assume xmalloc returns.
15713 Don't assume that stated character widths fit in int.

15715 * character.h (CHAR_WIDTH):
15716 * indent.c (MULTIBYTE_BYTES_WIDTH):
15717 Use sanitize_char_width to avoid undefined and/or bad behavior
15718 with outlandish widths.
15719 * character.h (sanitize_tab_width): Rename from sanitize_width,
15720 now that we have two such functions. All uses changed.
15721 (sanitize_char_width): New inline function.
15723 Don't assume that tab-width fits in int.
15724 * character.h (sanitize_width): New inline function.

15731 * fileio.c: Integer overflow issues with file modes.
15732 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15734 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

15738 * xterm.c: Don't go over XClientMessageEvent limit.
15739 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15740 (x_send_scroll_bar_event): Likewise. Check that the size does not
15741 exceed limits imposed by XClientMessageEvent, as well as the usual
15742 ptrdiff_t and size_t limits.
15744 * keyboard.c: Overflow, signedness and related fixes.
15745 (make_lispy_movement): Use same integer type in forward decl
15746 that is used in the definition.
15747 (read_key_sequence, keyremap_step):
15748 Change bufsize argument back to int, undoing my 2011-03-30 change.
15749 We prefer signed types, and int is wide enough here.
15750 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15751 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15752 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15753 length, not size_t. Use ptrdiff_t for index, not int.
15754 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15755 possibility of integer overflow.
15757 Overflow, signedness and related fixes for images.
15759 * dispextern.h (struct it.stack[0].u.image.image_id)
15760 (struct_it.image_id, struct image.id, struct image_cache.size)

15767 * xdisp.c (calc_pixel_width_or_height):
15768 * xfns.c (image_cache_refcount):
15769 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

15778 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15779 (lookup_image): Remove unnecessary tests.
15780 (xbm_image_p): Locals are now of int, not EMACS_INT,
15781 since parse_image_check makes sure they fit into int.
15782 (png_load, gif_load, svg_load_image):
15783 Prefer int to unsigned where either will do.
15784 (tiff_handler): New function, combining the cores of the
15785 old tiff_error_handler and tiff_warning_handler.
15786 This function is rewritten to use vsnprintf and thereby avoid
15787 stack buffer overflows. It uses only the features of vsnprintf
15788 that are common to both POSIX and native Microsoft.
15789 (tiff_error_handler, tiff_warning_handler): Use it.
15790 (tiff_load, gif_load, imagemagick_load_image):
15791 Don't assume :index value fits in 'int'.
15792 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15793 (imagemagick_load_image): Check that crop parameters fit into
15794 the integer types that MagickCropImage accepts. Don't assume
15795 Vimagemagick_render_type has a nonnegative value. Don't assume
15796 size_t fits in 'long'.
15797 (gs_load): Use printmax_t to print the widest integers possible.
15798 Check for integer overflow when computing image height and width.
15800 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15802 * xdisp.c (redisplay_window): Don't force window start if point
15803 will be invisible in the resulting window. (Bug#9324)

15807 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15808 the display spec is of the form `(space ...)'.
15809 (handle_display_spec): Return the value returned by
15810 handle_single_display_spec, not just 1 or zero.
15811 (handle_single_display_spec): If the display spec is of the form
15812 `(space ...)', and specifies display in the text area, return 2
15814 (try_cursor_movement): Check for the need to scroll more
15815 accurately, and prefer exact match for point under bidi.
15816 Don't advance `row' beyond the last row of the window.
15818 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15819 into disp_prop; all users changed.
15821 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

15833 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15834 buffers, return left-to-right.
15835 (set_cursor_from_row): Consider candidate row a win if its glyph
15836 represents a newline and point is on that newline. Fixes cursor
15837 positioning on the newline at EOL of R2L text within L2R
15838 paragraph, and vice versa.
15839 (try_cursor_movement): Check continued rows, in addition to
15840 continuation rows. Fixes unwarranted scroll when point enters a
15841 continued line of R2L text within an L2R paragraph, or vice versa.
15842 (cursor_row_p): Consider the case of point being equal to
15843 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15844 from the end of a short line to the beginning of a continued line
15845 of R2L text within L2R paragraph.
15846 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15847 composed characters.

15872 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15873 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15874 candidate is selected by the mouse, and that candidate has a
15875 composed character under the mouse.
15877 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15878 coordinates reported by pos-visible-in-window-p for a composed
15879 character in column zero.
15881 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15883 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15885 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15887 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15888 consider it a hit if to_charpos is anywhere in the range of the
15889 composed buffer positions.
15891 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15893 * image.c (gif_load): Don't assume that each subimage has the same
15894 dimensions as the base image. Handle disposal method that is
15895 "undefined" by the gif spec (Bug#9335).
15897 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15899 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15904 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15905 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15906 from an Org mode buffer to a Speedbar frame.
15908 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15909 a composition, take its buffer position from IT->cmp_it.charpos.
15910 Fixes cursor positioning at the beginning of a line that begins
15911 with a composed character.
15913 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15915 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15916 character bidirectional type, use STRONG_L instead. Fixes crashes
15917 in a buffer produced by `describe-categories'.
15919 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15920 members before the level stack, so they would be saved and
15921 restored when copying iterator state. Fixes incorrect reordering
15922 around TABs covered by display properties.
15924 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

15996 * xdisp.c (move_it_in_display_line_to): Don't invoke
15997 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15998 ppos_it. Fixes vertical cursor motion when line beginning is
15999 covered by an image. (Bug#9296)
16001 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16003 * nsterm.h (ns_run_ascript): Declare.

16010 the event loop. Get status from as_status (Bug#7276).
16012 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16013 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16014 the event loop (Bug#7276).

16033 * dispextern.h (Qframe_set_background_mode): Remove decl.
16035 * process.c (Fnetwork_interface_info): Declare local only if needed.
16037 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16039 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16040 (Fnetwork_interface_list): Allocate in increments of bytes instead
16041 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16042 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16044 (struct ifflag_def): notrailers is smart on OSX.
16045 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16046 Get hardware address with getifaddrs if available.
16048 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16050 * xdisp.c (iterate_out_of_display_property): xassert that
16051 IT->position is set to within IT->object's boundaries. Break from
16052 the loop as soon as EOB is reached; avoids infloops in redisplay
16053 when IT->position is set up wrongly due to some bug.
16054 Set IT->current to match the bidi iterator unconditionally.
16055 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16056 entry. Force push_it to save on the stack the current
16057 buffer/string position, to be restored by pop_it. Fix flags in
16058 the iterator structure wrt the object coming from a display
16059 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16060 properties. (Bug#9284)
16062 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16064 * fontset.c (fontset_get_font_group): Add proper type checks.
16067 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16069 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16070 and LC_VERSION_MIN_MACOSX.
16071 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16072 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16074 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16076 * xdisp.c (forward_to_next_line_start): Allow to use the
16077 no-display-properties-and-no-overlays under bidi display.
16078 Set disp_pos in the bidi iterator to avoid searches for display
16079 properties and overlays.
16081 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16083 * editfns.c (Fset_time_zone_rule): Document relationship with the
16086 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16087 the font entity extracted from the cache (Bug#8109).
16089 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16091 * composite.c (autocmp_chars): Don't reset point. That is done by
16092 restore_point_unwind (Bug#5984).
16094 2011-08-07 Juri Linkov <juri@jurta.org>
16096 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16097 to show the arg `TIME' instead of `TIMEVAL'.
16099 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16101 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16102 display property strides EOL and includes a newline, as in
16103 longlines-mode. (Bug#9254)
16104 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16105 word-wrap under bidirectional display. (Bug#9224)
16107 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16108 is non-zero, even if the data buffer is NULL. Fixes a crash in
16109 vertical-motion with longlines-mode. (Bug#9254)
16111 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16113 * bidi.c <bidi_cache_total_alloc>: Now static.
16114 (bidi_initialize): Initialize bidi_cache_total_alloc.
16116 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16119 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16120 amount allocated this far in `bidi_cache_total_alloc'.
16121 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16122 non-zero, only free the data buffer without restoring the cache
16123 contents. All callers changed.
16125 * dispextern.h (bidi_unshelve_cache): Update prototype.
16127 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16128 (move_it_in_display_line, move_it_to)
16129 (move_it_vertically_backward, move_it_by_lines): Replace the call
16130 to xfree to an equivalent call to bidi_unshelve_cache.
16131 (move_it_in_display_line_to): Fix logic of returning
16132 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16134 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16136 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16137 came from a string character with a `cursor' property. (Bug#9229)
16139 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16141 * Makefile.in (LIB_PTHREAD): New variable.
16142 (LIBES): Add LIB_PTHREAD (Bug#9216).
16144 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16145 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16147 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16149 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16151 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16153 * xterm.c (x_find_topmost_parent): New function.
16154 (x_set_frame_alpha): Find topmost parent window with
16155 x_find_topmost_parent and set the property there also (bug#9181).
16156 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16158 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16160 * callproc.c (Fcall_process): Avoid vfork clobbering
16161 the local vars buffer, coding_systems, current_dir.
16163 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16165 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16167 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16169 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16170 so that it is not optimized away.
16172 * xdisp.c (compute_display_string_pos): Remove unused local.
16174 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16176 Fix slow cursor motion and scrolling in large buffers with
16177 selective display, like Org Mode buffers. (Bug#9218)
16179 * dispextern.h (struct bidi_it): New member disp_prop_p.
16181 * xdisp.c: Remove one-slot cache of display string positions.
16182 (compute_display_string_pos): Accept an additional argument
16183 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16184 for a display string or property. If found, set DISP_PROP_P
16187 * bidi.c (bidi_fetch_char): Accept an additional argument
16188 DISP_PROP_P, and pass it to compute_display_string_pos.
16189 Only handle text covered by a display string if DISP_PROP_P is returned
16190 non-zero. All callers of bidi_fetch_char changed.
16192 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16194 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16196 2010-12-03 Don March <don@ohspite.net>
16198 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16199 last character M-[char] is translated to ESC [char] (bug#7541).
16201 2011-08-02 Kenichi Handa <handa@m17n.org>
16203 * lisp.h (uniprop_table): Extern it.
16205 * chartab.c (uniprop_table): Make it non-static.
16207 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16209 * xdisp.c (forward_to_next_line_start): Accept additional argument
16210 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16212 (reseat_at_next_visible_line_start): Use the bidi iterator state
16213 returned by forward_to_next_line_start to restore the state of
16214 it->bidi_it after backing up to previous newline. (Bug#9212)
16216 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16218 * regex.c (re_comp): Protoize.
16219 (re_exec): Fix return type.
16220 (regexec): Fix type of `ret'. (Bug#9203)
16222 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16224 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16225 This is needed if max-image-size is a floating-point number.
16227 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16229 * print.c (print_object): Print empty symbol as ##.
16231 * lread.c (read1): Read ## as empty symbol.
16233 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16235 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16236 setting frame foreground color (Bug#9175).
16237 (x_set_background_color): Likewise.
16239 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16240 contents (Bug#9176).
16241 (EmacsTooltip -init): Remove bezels and add shadows to
16244 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16245 or scroll bar (Bug#8470).
16247 * nsfont.m (nsfont_open): Remove assignment to voffset and
16248 unnecessary vars hshink, expand, hd, full_height, min_height.
16249 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16251 * nsterm.h (nsfont_info): Remove voffset field.
16253 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16255 Implement strike-through and overline on NextStep (Bug#8863).
16257 * nsfont.m (nsfont_open): Use underline position provided by font,
16258 instead of hard-coded value of 2.
16259 (nsfont_draw): Call ns_draw_text_decoration instead.
16261 * nsterm.h: Add declaration for ns_draw_text_decoration.
16263 * nsterm.m (ns_draw_text_decoration): New function for drawing
16264 underline, overline, and strike-through.
16265 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16266 ns_draw_text_decoration. Change treatment of cursor drawing to
16267 accommodate underlining, etc.
16269 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16271 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16274 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16276 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16277 Without this fix, if a signal arrives just after memory fills up,
16278 'malloc' might be invoked reentrantly.
16280 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16281 In other words, assume that every image size is allowed, on non-X
16282 hosts. This assumption is probably wrong, but it lets Emacs compile.
16284 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16286 * regex.c (re_iswctype): Convert return values to boolean.
16288 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16290 * xdisp.c (compute_display_string_pos): Don't use cached display
16291 string position if the buffer had its restriction changed.
16294 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16296 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16298 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16300 Integer signedness and overflow and related fixes. (Bug#9079)
16302 * bidi.c: Integer size and overflow fixes.
16303 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16304 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16305 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16306 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16307 (bidi_find_other_level_edge):
16308 Use ptrdiff_t instead of EMACS_INT where either will do.
16309 This works better on 32-bit hosts configured --with-wide-int.
16310 (bidi_cache_ensure_space): Check for size-calculation overflow.
16311 Use % rather than repeated addition, for better worst-case speed.
16312 Don't set bidi_cache_size until after xrealloc returns, because it
16314 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16315 (bidi_cache_ensure_space): Also check that the bidi cache size
16316 does not exceed that of the largest Lisp string or buffer. See Eli
16317 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16319 * alloc.c (__malloc_size_t): Remove.
16320 All uses replaced by size_t. See Andreas Schwab's note
16321 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16323 * image.c: Improve checking for integer overflow.
16324 (check_image_size): Assume that f is nonnull, since
16325 it is always nonnull in practice. This is one less thing to
16326 worry about when checking for integer overflow later.
16327 (x_check_image_size): New function, which checks for integer
16328 overflow issues inside X.
16329 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16330 This removes the need for a memory_full check.
16331 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16332 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16333 (xbm_read_bitmap_data): Change locals back to 'int', since
16334 their values must fit in 'int'.
16335 (xpm_load_image, png_load, tiff_load):
16336 Invoke x_create_x_image_and_pixmap earlier,
16337 to avoid much needless work if the image is too large.
16338 (tiff_load): Treat overly large images as if
16339 x_create_x_image_and_pixmap failed, not as malloc failures.
16340 (gs_load): Use x_check_image_size.
16342 * gtkutil.c: Omit integer casts.
16343 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16344 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16346 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16348 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16349 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16350 would wrongly return t on a 64-bit host.
16352 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16353 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16354 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16355 and therefore cause GCC to emit a bogus diagnostic in some cases.
16357 * image.c: Integer signedness and overflow and related fixes.
16358 This is not an exhaustive set of fixes, but it's time to
16359 record what I've got.
16360 (lookup_pixel_color, check_image_size): Remove redundant decls.
16361 (check_image_size): Don't assume that arbitrary EMACS_INT values
16362 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16363 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16364 (tiff_load, imagemagick_load_image):
16365 Check for overflow in size calculations.
16366 (x_create_x_image_and_pixmap): Remove unnecessary test for
16367 xmalloc returning NULL; that can't happen.
16368 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16369 (xpm_color_bucket): Use better integer hashing function.
16370 (xpm_cache_color): Don't possibly over-allocate memory.
16371 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16372 (gif_memory_source):
16373 Use ptrdiff_t, not int or size_t, to record sizes.
16374 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16375 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16376 either works, as we prefer signed integers.
16377 (tiff_read_from_memory, tiff_write_from_memory):
16378 Return tsize_t, not size_t, since that's what the TIFF API wants.
16379 (tiff_read_from_memory): Don't fail simply because the read would
16380 go past EOF; instead, return a short read.
16381 (tiff_load): Omit no-longer-needed casts.
16382 (Fimagemagick_types): Don't assume size fits into 'int'.
16384 Improve hashing quality when configured --with-wide-int.
16385 * fns.c (hash_string): New function, taken from sxhash_string.
16386 Do not discard information about ASCII character case; this
16387 discarding is no longer needed.
16388 (sxhash-string): Use it. Change sig to match it. Caller changed.
16389 * lisp.h: Declare it.
16390 * lread.c (hash_string): Remove, since we now use fns.c's version.
16391 The fns.c version returns a wider integer if --with-wide-int is
16392 specified, so this should help the quality of the hashing a bit.
16394 * emacs.c: Integer overflow minor fix.
16395 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16396 Define only if GNU_LINUX.
16397 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16399 * dispnew.c: Integer signedness and overflow fixes.
16400 Remove unnecessary forward decls, that were a maintenance hassle.
16401 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16403 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16404 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16405 (prepare_desired_row, line_draw_cost):
16406 Use int, not unsigned, where either works.
16407 (save_current_matrix, restore_current_matrix):
16408 Use ptrdiff_t, not size_t, where either works.
16409 (init_display): Check for overflow more accurately, and without
16410 relying on undefined behavior.
16412 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16413 Remove, replacing with the new symbols in lisp.h. All uses changed.
16414 * fileio.c (make_temp_name):
16415 * filelock.c (lock_file_1, lock_file):
16416 * xdisp.c (message_dolog):
16417 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16418 Use pMd etc. instead.
16419 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16420 replacing the pWIDE etc. symbols removed from editfns.c.
16422 * keyboard.h (num_input_events): Now uintmax_t.
16423 This is (very slightly) less likely to mess up due to wraparound.
16426 * buffer.c: Integer signedness fixes.
16427 (alloc_buffer_text, enlarge_buffer_text):
16428 Use ptrdiff_t rather than size_t when either will do, as we prefer
16431 * alloc.c: Integer signedness and overflow fixes.
16432 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16433 (__malloc_size_t): Default to size_t, not to int.
16434 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16435 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16436 Prefer ptrdiff_t to size_t when either would do, as we prefer
16438 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16439 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16440 Now const. Initialize with values that are in range even if char
16442 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16443 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16444 These functions do the right thing with sizes > 2**32.
16445 (check_depth): Now ptrdiff_t, not int.
16446 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16447 Adjust to new way of storing sizes. Check for size overflow bugs
16449 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16450 slightly wrong anyway, as it missed one instance of
16451 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16452 (refill_memory_reserve): Omit needless cast to size_t.
16453 (mark_object_loop_halt): Mark as externally visible.
16455 * xselect.c: Integer signedness and overflow fixes.
16456 (Fx_register_dnd_atom, x_handle_dnd_message):
16457 Use ptrdiff_t, not size_t, since we prefer signed.
16458 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16459 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16460 x_dnd_atoms_size and x_dnd_atoms_length.
16462 * doprnt.c: Prefer signed to unsigned when either works.
16464 * doprnt.c (doprnt):
16466 * xdisp.c (vmessage):
16467 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16468 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16469 prefer signed arithmetic to avoid comparison confusion.
16470 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16471 but is a bit tricky.
16473 Assume freestanding C89 headers, string.h, stdlib.h.
16474 * data.c, doprnt.c, floatfns.c, print.c:
16475 Include float.h unconditionally.
16476 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16477 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16478 * regex.c: Likewise for stddef.h, string.h.
16479 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16480 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16481 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16482 (STDC_HEADERS): Remove obsolete defines.
16483 * sysdep.c: Include limits.h unconditionally.
16485 Assume support for memcmp, memcpy, memmove, memset.
16486 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16487 * regex.c (memcmp, memcpy):
16488 Remove; we assume C89 now.
16490 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16491 (__malloc_safe_bcopy): Remove; no longer needed.
16493 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16494 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16495 well either way, and we prefer signed to unsigned.
16497 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16499 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16500 closes the connection while we're reading (bug#9182).
16502 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16504 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16505 are specified (Bug#9168).
16507 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16509 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16510 Found by GCC static checking and --with-wide-int on a 32-bit host.
16512 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16514 * xdisp.c (compute_display_string_pos): Fix logic of caching
16515 previous display string position. Initialize cached_prev_pos to
16516 -1. Fixes slow-down at the beginning of a buffer.
16518 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16520 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16521 for attrs[LFACE_FONTSET_INDEX].
16523 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16525 * xml.c (parse_region): Remove unused local
16526 that was recently introduced.
16528 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16530 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16531 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16533 * xdisp.c (move_it_in_display_line_to): Record the best matching
16534 position for TO_CHARPOS while scanning the line, and restore it on
16535 exit if none of the characters scanned was an exact match.
16536 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16537 when exact match is impossible due to invisible text, and the
16538 lines are truncated.
16540 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16542 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16545 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16547 Fix a significant slow-down of cursor motion with C-n, C-p,
16548 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16549 auto-repeat under bidi redisplay in fontified buffers.
16550 * xdisp.c (compute_stop_pos_backwards): New function.
16551 (next_element_from_buffer): Call compute_stop_pos_backwards to
16552 find a suitable prev_stop when we find ourselves before
16554 (reseat): Don't look for prev_stop, as that could mean a very long
16556 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16557 <cached_disp_overlay_modiff>: Cache for last found display string
16559 (compute_display_string_pos): Return the cached position if asked
16560 about the same buffer in the same area of character positions, and
16561 the buffer wasn't changed since the time the display string
16562 position was cached.
16564 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16566 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16567 is an integer, which is important for empty lines. (Bug#9149)
16569 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16571 * frame.c (Fmodify_frame_parameters): In tty case, update the
16572 default face if necessary (Bug#4238).
16574 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16576 * editfns.c (Fstring_to_char): No need to explain what a character
16577 is in the docstring (Bug#6576).
16579 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16581 * xml.c (parse_region): Make sure we always return a tree.
16583 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16585 * xml.c (parse_region): If a document contains only comments,
16588 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16590 * xml.c (make_dom): Return comments, too.
16592 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16595 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16596 and the surrounding thread.
16597 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16598 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16599 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16601 * s/openbsd.h (BROKEN_SIGIO): Define.
16602 * unexelf.c (unexec) [__OpenBSD__]:
16603 Don't update the .mdebug section of the Alpha COFF symbol table.
16605 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16607 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16610 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16612 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16613 This fixes some race conditions on the permissions of any newly
16616 * alloc.c (valid_pointer_p): Use pipe, not open.
16617 This fixes some permissions issues when debugging.
16619 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16620 If fchown fails to set both uid and gid, try to set just gid,
16621 as that is sometimes allowed. Adjust the file's mode to eliminate
16622 setuid or setgid bits that are inappropriate if fchown fails.
16624 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16626 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16627 to compare Lisp_Objects.

16632 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16634 * lread.c (read_integer): Unread even EOF character.
16635 (read1): Likewise. Properly record start position of symbol.
16637 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16638 symbol character follows.
16640 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16642 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16643 This works around a problem with the previous change to Fcopy_file.
16644 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16645 and without this change, GCC might complain about discarding
16646 fchown's return value.
16648 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16650 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16652 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16654 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16656 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16658 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16659 it's used from the C level.
16661 * process.c: Use the same condition for POLL_FOR_INPUT in both
16662 keyboard.c and process.c (bug#1858).
16664 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16666 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16667 (Fgnutls_boot): Use it.
16669 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16671 * doc.c (Fsubstitute_command_keys): Revert last change.
16673 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16675 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16676 quotes the next character, and doesn't affect other longer
16677 sequences (bug#8935).
16679 * lread.c (syms_of_lread): Clarify that is isn't only
16680 `eval-buffer' and `eval-defun' that's affected by
16681 `lexical-binding' (bug#8460).
16683 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16685 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16686 bidi redisplay when a line includes both an image and is truncated.
16688 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16690 Fix minor problems found by static checking.
16691 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16692 (elsz): Now a signed constant, not a size_t var. We prefer signed
16693 types to unsigned, to avoid integer comparison confusion. Without
16694 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16695 "cannot optimize loop, the loop counter may overflow", a symptom
16697 * indent.c (Fvertical_motion): Mark locals as initialized.
16698 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16700 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16702 * search.c (Fre_search_backward): Mention `case-fold-search' in
16703 all the re_search_* functions (bug#8138).

16718 bidi_it->string.schars.
16719 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to

16723 buffer position was specified. Initialize paragraph_embedding to
16725 (reseat_to_string): Initialize the bidi iterator.
16726 (display_string): If we need to ignore text properties of
16727 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16728 original value of -1 will not work with bidi.)
16729 (compute_display_string_pos): First arg is now struct
16730 `text_pos *'; all callers changed. Support display properties on
16732 (compute_display_string_end): Support display properties on Lisp
16734 (init_iterator, reseat_1, reseat_to_string): Initialize the
16735 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16736 when iterating on a string not from display properties).
16737 (compute_display_string_pos, compute_display_string_end):
16738 Fix calculation of the object to scan. Fixes an error when using
16740 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16741 base_level_stop; instead, set base_level_stop to BEGV.
16742 Fixes crashes in vertical-motion.
16743 (next_element_from_buffer): Improve commentary for when
16744 the iterator is before prev_stop.
16745 (init_iterator): Initialize bidi_p from the default value of
16746 bidi-display-reordering, not from buffer-local value. Use the
16747 buffer-local value only if initializing for buffer iteration.
16748 (handle_invisible_prop): Support invisible properties on strings
16749 that are being bidi-reordered.
16750 (set_iterator_to_next): Support bidi reordering of C strings and
16752 (next_element_from_string): Support bidi reordering of Lisp

16756 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16757 (init_iterator): Don't initialize it->bidi_p for strings
16759 (reseat_to_string): Initialize it->bidi_p for strings here.
16760 (next_element_from_string, next_element_from_c_string)
16761 (next_element_from_buffer): Add xassert's for correspondence

16766 character that is not the first one in the visual order.
16767 (get_visually_first_element): New function, refactored from common
16768 parts of next_element_from_buffer, next_element_from_string, and
16769 next_element_from_c_string.
16770 (tool_bar_lines_needed, redisplay_tool_bar)
16771 (display_menu_bar): Force left-to-right direction. Add a FIXME
16772 comment for making that be controlled by a user option.
16773 (push_it, pop_it): Save and restore the state of the
16774 bidi iterator. Save and restore the bidi_p flag.
16775 (pop_it): Iterate out of display property for string iteration as
16777 (iterate_out_of_display_property): Support iteration over strings.
16778 (handle_single_display_spec): Set up it->bidi_it for iteration
16779 over a display string, and call bidi_init_it.
16780 (handle_single_display_spec, next_overlay_string)
16781 (get_overlay_strings_1, push_display_prop): Set up the bidi
16782 iterator for displaying display or overlay strings.
16783 (forward_to_next_line_start): Don't use the shortcut if
16785 (back_to_previous_visible_line_start): If handle_display_prop
16786 pushed the iterator stack, restore the internal state of the bidi
16787 iterator by calling bidi_pop_it same number of times.
16788 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16789 and we are bidi-iterating, don't decrement the iterator position;
16790 instead, set the first_elt flag in the bidi iterator, to produce
16792 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16793 (push_display_prop): xassert that we are iterating a buffer.
16794 (push_it, pop_it): Save and restore paragraph_embedding member.
16795 (handle_single_display_spec, next_overlay_string)
16796 (get_overlay_strings_1, reseat_1, reseat_to_string)
16797 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16798 correctly. Don't assume unibyte strings are not bidi-reordered.
16799 (compute_display_string_pos)
16800 (compute_display_string_end): Fix handling the case of C string.
16801 (push_it, pop_it): Save and restore from_disp_prop_p.

16807 property. Fix a typo in popping stretch info. Add an assertion
16808 for verifying that the iterator position is in sync with the bidi
16810 (handle_single_display_spec, get_overlay_strings_1)
16811 (push_display_prop): Fix initialization of paragraph direction for
16812 string when that of the parent object is not yet determined.

16824 (try_scrolling, redisplay_window, display_line): Use them when
16825 saving a temporary copy of the iterator and restoring it back.
16826 (back_to_previous_visible_line_start, reseat_1)
16827 (init_iterator): Empty the bidi cache "stack".
16828 (move_it_in_display_line_to): If iterator ended up at
16829 EOL, but we never saw any buffer positions smaller than
16830 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16831 motion in bidi-reordered lines.

16833 immediately before the call to set_iterator_to_next. Fixes cursor
16834 motion in bidi-reordered lines with stretch glyphs and strings
16835 displayed in margins. (Bug#8133) (Bug#8867)
16836 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16838 (pos_visible_p): Support positions in bidi-reordered lines.
16839 Save and restore bidi cache.
16841 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16842 (bidi_paragraph_info): Delete unused struct.
16843 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16844 (bidi_cache_start): New variable.

16860 Support iteration over a string.
16861 (bidi_set_sor_type, bidi_resolve_explicit_1)
16862 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16863 can now be zero (for strings); special values 0 and -1 were
16864 changed to -1 and -2, respectively.
16865 (bidi_char_at_pos): New function.
16866 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16955 The old code sometimes used this field without initializing it.
16957 * alloc.c (gc_sweep): Don't read past end of array.
16958 In theory, the old code could also have corrupted Emacs internals,
16959 though it'd be very unlikely.

17224 This isn't true in general, and it's particularly not true
17225 if Emacs is configured with --with-wide-int.
17226 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17263 Random fixes. E.g., (random) never returned negative values.
17264 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17265 subseconds part to the entropy, as that's a bit more random.
17266 Prefer signed to unsigned, since the signedness doesn't matter and
17267 in general we prefer signed. When given a limit, use a
17268 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17269 latter isn't right if USE_2_TAGS_FOR_INTS.
17270 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17271 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17283 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17284 This is more efficient than Ffile_directory_p and avoids a minor race.
17286 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17288 * buffer.c (Foverlay_put): Say what the return value is
17291 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17292 is a directory before asking whether to use the file name

17295 error be more correct.
17297 * fns.c (Frequire): Remove the mention of the .gz files, since
17298 that's installation-specific, but keep the mention of

17311 Qgnutls_bootprop_verify_error (which is no longer used).
17313 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17314 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17315 Also (re)move comments that are misplaced or no longer relevant.

17344 * lread.c (syms_of_lread): Mention single symbols defined by
17345 `defvar' or `defconst' (bug#7154).
17347 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17348 (Frequire): Mention get-load-suffixes.

17416 * eval.c (struct backtrace): Simplify and port the data structure.
17417 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17418 signed bit field, as this assumption is not portable and it makes
17419 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17420 "char debug_on_exit : 1" as this is not portable either; instead,
17421 use the portable "unsigned int debug_on_exit : 1". Remove unused
17422 member evalargs. Remove obsolete comments about cc bombing out.
17424 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17496 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17497 and use min_width/height from frames size_hint to set
17498 min_width/height (Bug#8919).

17591 (PRINTPREPARE, printchar, strout):
17592 Don't set size unless allocation succeeds.
17594 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17595 for sizes. Check for string overflow more accurately.

17606 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17608 * lread.c: Integer overflow fixes.
17609 (read_integer): Radix is now EMACS_INT, not int,
17610 to improve quality of diagnostics for out-of-range radices.
17611 Calculate buffer size correctly for out-of-range radices.
17612 (read1): Check for integer overflow in radices, and in
17613 read-circle numbers.
17614 (read_escape): Avoid int overflow.
17615 (Fload, openp, read_buffer_size, read1)
17616 (substitute_object_recurse, read_vector, read_list, map_obarray):

17632 2011-06-22 Leo Liu <sdl.web@gmail.com>
17634 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17635 Move to minibuffer.el.
17637 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17639 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17640 The following patches are for when GLYPH_DEBUG && !XASSERT.
17641 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17642 * dispnew.c (flush_stdout):
17643 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17644 Mark as externally visible.
17645 * dispnew.c (check_window_matrix_pointers): Now static.

17654 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17656 (debug_method_add): Use va_list and vsprintf rather than relying
17657 on undefined behavior with wrong number of arguments.
17658 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17659 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17660 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17661 since we're not interested in debugging glyphs with old libraries.
17662 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17663 GCC 4.6.0's static checking.
17665 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17684 (.bitmaps_last, struct x_output.icon_bitmap):
17685 Use ptrdiff_t, not int, for bitmap indexes.

17700 (overlays_at, overlays_in): Check for size-calculation overflow.
17702 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17704 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17705 (x_session_initialize): Do not assume string length fits in int.
17707 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17708 This is unlikely, but can occur if DPI is outlandish.
17710 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17711 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

17753 Don't assume pid_t and time_t fit in unsigned long.
17754 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17755 (current_lock_owner): Prefer signed type for sizes.
17756 Use memcpy, not strncpy, where memcpy is what is really wanted.
17757 Don't assume (via atoi) that time_t and pid_t fit in int.
17758 Check for time_t and/or pid_t out of range, e.g., via a network share.
17759 Don't alloca where an auto var works fine.
17761 * fileio.c: Fix some integer overflow issues.

17786 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17788 * lread.c (invalid_syntax): Omit length argument.
17789 All uses changed. This doesn't fix a bug, but it simplifies the
17790 code away from its former Hollerith-constant appearance, and it's
17791 one less 'int' to worry about when looking at integer-overflow issues.
17792 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17794 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17795 This didn't break anything, but it didn't help either.
17796 It's confusing to put a bogus integer in a place where the actual
17797 value does not matter.
17798 (LIST_END_P): Remove unused macro and its bogus comment.
17799 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17801 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17802 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17804 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17805 We prefer signed types, and the value cannot exceed the EMACS_INT
17806 range anyway (because otherwise the length would not be representable).
17807 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17808 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17809 This avoids a GCC warning when WIDE_EMACS_INT.
17811 * indent.c (sane_tab_width): New function.
17812 (current_column, scan_for_column, Findent_to, position_indentation)
17813 (compute_motion): Use it. This is just for clarity.
17814 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17816 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17818 * lisp.h (lint_assume): New macro.
17819 * composite.c (composition_gstring_put_cache):
17820 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17822 * editfns.c, insdel.c:
17823 Omit unnecessary forward decls, to simplify future changes.
17825 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17827 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17829 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17830 Use much-faster test for byte-length change.
17831 Don't assume string byte-length fits in 'int'.
17832 Check that character arg fits in 'int'.
17833 (mapcar1): Declare byte as byte, for clarity.
17835 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17837 * fns.c (concat): Catch string overflow earlier.
17838 Do not rely on integer wraparound.
17840 * dispextern.h (struct it.overlay_strings_charpos)
17841 (struct it.selective): Now EMACS_INT, not int.
17842 * xdisp.c (forward_to_next_line_start)
17843 (back_to_previous_visible_line_start)
17844 (reseat_at_next_visible_line_start, next_element_from_buffer):
17845 Don't arbitrarily truncate the value of 'selective' to int.
17847 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17849 * composite.c: Don't truncate sizes to 'int'.
17850 (composition_gstring_p, composition_reseat_it)
17851 (composition_adjust_point): Use EMACS_INT, not int.
17852 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17853 not EMACS_UINT, for indexes.
17855 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17857 * buffer.c: Include <verify.h>.
17858 (struct sortvec.priority, struct sortstr.priority):
17859 Now EMACS_INT, not int.
17860 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17861 (struct sortstr.size, record_overlay_string)
17862 (struct sortstrlist.size, struct sortlist.used):
17863 Don't truncate size to int.
17864 (record_overlay_string): Check for size-calculation overflow.
17865 (init_buffer_once): Check at compile-time, not run-time.
17867 2011-06-22 Jim Meyering <meyering@redhat.com>
17869 Don't leak an XBM-image-sized buffer
17870 * image.c (xbm_load): Free the image buffer after using it.
17872 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17875 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17876 that Sun C diagnosed.
17877 * fns.c (secure_hash): Fix pointer signedness issue.
17878 * intervals.c (static_offset_intervals): New function.
17879 (offset_intervals): Use it.
17881 2011-06-21 Leo Liu <sdl.web@gmail.com>
17884 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17887 * fns.c (secure_hash): Rename from crypto_hash_function and change
17888 the first arg to accept symbols.
17889 (Fsecure_hash): New primitive.
17890 (syms_of_fns): New symbols.
17892 2011-06-20 Deniz Dogan <deniz@dogan.se>
17894 * process.c (Fset_process_buffer): Clarify return value in
17897 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17899 * dispnew.c (add_window_display_history): Use BVAR.
17901 * xdisp.c (debug_method_add): Use BVAR.
17902 (check_window_end, dump_glyph_matrix, dump_glyph)
17903 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17905 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17908 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17909 check till after the cache is created in init_frame_faces.
17911 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17913 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17915 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17917 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17918 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17919 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17921 Improve buffer-overflow checking (Bug#8873).
17922 * fileio.c (Finsert_file_contents):
17923 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17924 Remove the old (too-loose) buffer overflow checks.
17925 They weren't needed, since make_gap checks for buffer overflow.
17926 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17927 The old code merely checked for Emacs fixnum overflow, and relied
17928 on undefined (wraparound) behavior. The new code avoids undefined
17929 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17931 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17932 Tune. Don't use wider integers than needed. Don't use alloca.
17933 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17935 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17937 * insdel.c, lisp.h (buffer_overflow): New function.
17938 (insert_from_buffer_1, replace_range, replace_range_2):
17939 * insdel.c (make_gap_larger):
17940 * editfns.c (Finsert_char):
17941 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17943 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17945 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17947 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17949 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17950 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17952 * fileio.c: Don't assume EMACS_INT fits in off_t.
17953 (emacs_lseek): New static function.
17954 (Finsert_file_contents, Fwrite_region): Use it.
17955 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17957 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17959 * fns.c: Don't overflow int when computing a list length.
17960 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17961 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17962 truncation on 64-bit hosts. Check for QUIT every
17963 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17964 faster and is responsive enough.
17965 (Flength): Report an error instead of overflowing an integer.
17966 (Fsafe_length): Return a float if the value is not representable
17967 as a fixnum. This shouldn't happen except in contrived situations.
17968 (Fnthcdr, Fsort): Don't assume list length fits in int.
17969 (Fcopy_sequence): Don't assume vector length fits in int.
17971 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17972 (header_size, word_size): New constants.
17973 (allocate_vectorlike): Don't check size overflow here.
17974 (allocate_vector): Check it here instead, since this is the only
17975 caller of allocate_vectorlike that could cause overflow.
17976 Check that the new vector's length is representable as a fixnum.
17978 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17979 The previous code was bogus. For example, next_almost_prime (32)
17980 returned 39, which is undesirable as it is a multiple of 3; and
17981 next_almost_prime (24) returned 25, which is a multiple of 5 so
17982 why was the code bothering to check for multiples of 7?
17984 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17986 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17988 Variadic C functions now count arguments with ptrdiff_t.
17989 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17990 Back then I didn't know that the Emacs coding style prefers signed int.
17991 Also, in the meantime I found a few more instances where arguments
17992 were being counted with int, which may truncate counts on 64-bit
17993 machines, or EMACS_INT, which may be unnecessarily wide.
17994 * lisp.h (struct Lisp_Subr.function.aMANY)
17995 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17996 Arg counts are now ptrdiff_t, not size_t.
17997 All variadic functions and their callers changed accordingly.
17998 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17999 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18000 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18001 * callint.c (Fcall_interactively): Check arg count for overflow,
18002 to avoid potential buffer overrun. Use signed char, not 'int',
18003 for 'varies' array, so that we needn't bother to check its size
18004 calculation for overflow.
18005 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18006 * eval.c (apply_lambda):
18007 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18008 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18009 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18011 * callint.c (Fcall_interactively): Don't use index var as event count.
18013 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18014 * mem-limits.h (SIZE): Remove; no longer used.
18016 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18018 Remove unnecessary casts.
18019 * xterm.c (x_term_init):
18020 * xfns.c (x_set_border_pixel):
18021 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18022 These aren't needed now that we assume ANSI C.
18024 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18025 It's more likely to cause problems (due to unsigned overflow)
18028 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18030 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18032 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18034 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18036 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18038 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18040 GLYPH_CODE_FACE returns EMACS_INT, not int.
18041 * dispextern.h (merge_faces):
18042 * xfaces.c (merge_faces):
18043 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18044 Don't assume EMACS_INT fits in int.
18046 * character.h (CHAR_VALID_P): Remove unused parameter.
18047 * fontset.c, lisp.h, xdisp.c: All uses changed.
18049 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18051 * fns.c (concat): Minor tuning based on overflow analysis.
18052 This doesn't fix any bugs. Use int to hold character, instead
18053 of constantly refetching from Emacs object. Use XFASTINT, not
18054 XINT, for value known to be a character. Don't bother comparing
18055 a single byte to 0400, as it's always less.
18057 * floatfns.c (Fexpt):
18058 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18060 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18063 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18065 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18066 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18067 incorrectly succeed when S was a string, because 4294967386 was
18068 truncated before it was used.
18070 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18071 Otherwise, an out-of-range integer could cause undefined behavior
18074 * composite.c: Use int, not EMACS_INT, for characters.
18075 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18076 EMACS_INT, for values that are known to be in character range.
18077 This doesn't fix any bugs but is the usual style inside Emacs and
18078 may generate better code on 32-bit machines.
18080 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18081 This is for reasons similar to the recent CHAR_STRING fix.
18082 * charset.c (Fencode_char): Check that character arg is actually
18083 a character. Pass an int to ENCODE_CHAR.
18084 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18085 wider than 'int', as a compile-time check to prevent future regressions
18088 * character.c (char_string): Remove unnecessary casts.
18090 Make sure a 64-bit char is never passed to CHAR_STRING.
18091 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18092 by silently ignoring the top 32 bits, allowing some values
18093 that were far too large to be valid characters.
18094 * character.h: Include <verify.h>.
18095 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18096 arguments are no wider than unsigned, as a compile-time check
18097 to prevent future regressions in this area.
18099 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18100 (Fsubst_char_in_region):
18102 * xdisp.c (decode_mode_spec_coding):
18103 Adjust to CHAR_STRING's new requirement.
18104 * editfns.c (Finsert_char, Fsubst_char_in_region):
18105 * fns.c (concat): Check that character args are actually
18106 characters. Without this test, these functions did the wrong
18107 thing with wildly out-of-range values on 64-bit hosts.
18109 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18110 These casts should not be needed on 32-bit hosts, either.
18111 * keyboard.c (read_char):
18112 * lread.c (Fload): Remove casts to unsigned.
18114 * lisp.h (UNSIGNED_CMP): New macro.
18115 This fixes comparison bugs on 64-bit hosts.
18116 (ASCII_CHAR_P): Use it.
18117 * casefiddle.c (casify_object):
18118 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18119 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18120 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18121 * dispextern.h (FACE_FROM_ID):
18122 * keyboard.c (read_char): Use UNSIGNED_CMP.
18124 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18125 not to EMACS_INT, to avoid GCC warning.
18127 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18129 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18130 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18131 isn't needed on 32-bit machines.
18133 * buffer.c (Fgenerate_new_buffer_name):
18134 Use EMACS_INT for count, not int.
18135 (advance_to_char_boundary): Return EMACS_INT, not int.
18137 * data.c (Qcompiled_function): Now static.
18139 * window.c (window_body_lines): Now static.
18141 * image.c (gif_load): Rename local to avoid shadowing.
18143 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18144 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18145 * alloc.c (make_save_value): Integer argument is now of type
18146 ptrdiff_t, not int.
18147 (mark_object): Use ptrdiff_t, not int.
18148 * lisp.h (pD): New macro.
18149 * print.c (print_object): Use it.
18151 * alloc.c: Use EMACS_INT, not int, to count objects.
18152 (total_conses, total_markers, total_symbols, total_vector_size)
18153 (total_free_conses, total_free_markers, total_free_symbols)
18154 (total_free_floats, total_floats, total_free_intervals)
18155 (total_intervals, total_strings, total_free_strings):
18156 Now EMACS_INT, not int. All uses changed.
18157 (Fgarbage_collect): Compute overall total using a double, so that
18158 integer overflow is less likely to be a problem. Check for overflow
18159 when converting back to an integer.
18160 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18161 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18162 These were 'int' variables that could overflow on 64-bit hosts;
18163 they were never used, so remove them instead of repairing them.
18164 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18165 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18166 Previously, this ceilinged at INT_MAX, but that doesn't work on
18168 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18170 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18171 (allocate_vectorlike): Check for ptrdiff_t overflow.
18172 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18173 when a (possibly-narrower) signed value would do just as well.
18174 We prefer using signed arithmetic, to avoid comparison confusion.
18176 * alloc.c: Catch some string size overflows that we were missing.
18177 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18178 for convenience in STRING_BYTES_MAX.
18179 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18180 The definition here is exact; the one in lisp.h was approximate.
18181 (allocate_string_data): Check for string overflow. This catches
18182 some instances we weren't catching before. Also, it catches
18183 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18184 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18185 and ptrdiff_t and EMACS_INT are both 64 bits.
18187 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18188 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18189 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18191 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18193 * alloc.c (Fmake_string): Check for out-of-range init.
18195 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18197 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18199 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18201 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18202 xg_get_default_scrollbar_width.
18204 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18205 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18206 (style_changed_cb): Call update_theme_scrollbar_width and call
18207 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18208 all frames (Bug#8505).
18209 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18210 Call gtk_window_set_resizable if HAVE_GTK3.
18211 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18212 and height if HAVE_GTK3 (Bug#8505).
18213 (scroll_bar_width_for_theme): New variable.
18214 (update_theme_scrollbar_width): New function.
18215 (xg_get_default_scrollbar_width): Move code to
18216 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18217 (xg_initialize): Call update_theme_scrollbar_width.
18219 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18221 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18223 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18225 * frame.c (make_frame): Call other_buffer_safely instead of
18228 * window.c (temp_output_buffer_show): Call display_buffer with
18229 second argument Vtemp_buffer_show_specifiers and reset latter
18230 immediately after the call.
18231 (Vtemp_buffer_show_specifiers): New variable.
18232 (auto_window_vscroll_p, next_screen_context_lines)

18681 (Fframe_root_window, Fframe_first_window)
18682 (Fframe_selected_window): Move here from frame.c. Accept frame
18683 or arbitrary window as argument. Update doc-strings.
18684 (Fminibuffer_window): Move up in code.
18685 (Fwindow_minibuffer_p): Move up in code and simplify.
18686 (Fset_frame_selected_window): Move here from frame.c.
18688 (Fselected_window, select_window, Fselect_window): Move up in
18689 code. Minor doc-string fixes.
18691 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18693 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18694 Do not assume that spare memory exists; that assumption is valid
18695 only if SYSTEM_MALLOC.
18696 (LARGE_REQUEST): New macro, so that the issue of large requests
18697 is separated from the issue of spare memory.
18699 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18701 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18718 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
18720 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
18722 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

18725 (x_clipboard_manager_save): Add return value.
18726 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
18727 New error handlers.
18728 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18729 Obey Vx_select_enable_clipboard_manager. Catch errors in
18730 x_clipboard_manager_save (Bug#8779).
18731 (Vx_select_enable_clipboard_manager): New variable.
18732 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18734 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18736 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18738 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18740 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18741 in the current matrix if keep_current_p is non-zero.

18745 * bidi.c (bidi_level_of_next_char): Fix last change.
18747 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18749 Support bidi reordering of text covered by display properties.
18751 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18752 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18753 (bidi_cache_search, bidi_cache_iterator_state)
18754 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18755 (bidi_level_of_next_char, bidi_move_to_visually_next):
18756 Support character positions inside a run of characters covered by a
18758 (bidi_paragraph_init, bidi_resolve_explicit_1)
18759 (bidi_level_of_next_char): Call bidi_fetch_char and
18760 bidi_fetch_char_advance instead of FETCH_CHAR and
18761 FETCH_CHAR_ADVANCE.
18762 (bidi_init_it): Initialize new members.
18763 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18765 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18766 instead of using explicit *_CHAR codes.
18767 (bidi_resolve_explicit, bidi_resolve_weak):
18768 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18769 bidirectional text is supported only in multibyte buffers.
18770 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18771 it to initialize the frame_window_p member of struct bidi_it.
18772 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18773 (bidi_resolve_explicit, bidi_resolve_weak)

18775 bidi_it->nchars is non-positive.
18776 (bidi_level_of_next_char): Don't try to lookup the cache for the
18777 next/previous character if nothing is cached there yet, or if we
18778 were just reseat()'ed to a new position.
18780 * xdisp.c (set_cursor_from_row): Set start and stop points
18781 according to the row's direction when priming the loop that looks
18782 for the glyph on which to display cursor.
18783 (single_display_spec_intangible_p): Function deleted.
18784 (display_prop_intangible_p): Reimplement to call
18785 handle_display_spec instead of single_display_spec_intangible_p.
18786 Accept 3 additional arguments needed by handle_display_spec.
18787 This fixes incorrect cursor motion across display property with complex
18788 values: lists, `(when COND...)' forms, etc.
18789 (single_display_spec_string_p): Support property values that are
18790 lists with the argument STRING its top-level element.
18791 (display_prop_string_p): Fix the condition for processing a
18792 property that is a list to be consistent with handle_display_spec.
18793 (handle_display_spec): New function, refactored from the
18794 last portion of handle_display_prop.
18795 (compute_display_string_pos): Accept additional argument
18796 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18797 value of a `display' property is a "replacing spec".
18798 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18799 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18800 the display property, but just return a value indicating whether
18801 the display property will replace the characters it covers.
18802 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18803 frame_window_p members of struct bidi_it.
18804 (compute_display_string_pos, compute_display_string_end):
18806 (push_it): Accept second argument POSITION, where pop_it should
18807 jump to continue iteration.
18808 (reseat_1): Initialize bidi_it.disp_pos.
18810 * keyboard.c (adjust_point_for_property): Adjust the call to
18811 display_prop_intangible_p to its new signature.
18813 * dispextern.h (struct bidi_it): New member frame_window_p.
18814 (bidi_init_it): Update prototypes.
18815 (display_prop_intangible_p): Update prototype.
18816 (compute_display_string_pos, compute_display_string_end):
18817 Declare prototypes.
18818 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18821 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18823 Malloc failure behavior now depends on size of allocation.
18824 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18825 * lisp.h: Change signatures accordingly.
18826 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18827 All callers changed. (Bug#8762)
18829 * gnutls.c: Use Emacs's memory allocators.
18830 Without this change, the gnutls library would invoke malloc etc.
18831 directly, which causes problems on non-SYNC_INPUT hosts, and which
18832 runs afoul of improving memory_full behavior. (Bug#8761)
18833 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18834 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18835 xfree instead of the default malloc, realloc, free.
18836 (Fgnutls_boot): No need to check for memory allocation failure,
18837 since xmalloc does that for us.
18839 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18840 * category.c (hash_get_category_set):
18841 * ccl.c (ccl_driver):
18842 * charset.c (Fdefine_charset_internal):
18843 * charset.h (struct charset.hash_index):
18844 * composite.c (get_composition_id, gstring_lookup_cache)
18845 (composition_gstring_put_cache):
18846 * composite.h (struct composition.hash_index):
18847 * dispextern.h (struct image.hash):
18848 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18849 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18850 (hashfn_equal, hashfn_user_defined, make_hash_table)
18851 (maybe_resize_hash_table, hash_lookup, hash_put)
18852 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18853 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18854 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18855 * image.c (make_image, search_image_cache, lookup_image)
18856 (xpm_put_color_table_h):
18857 * lisp.h (struct Lisp_Hash_Table):
18858 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18859 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18860 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18861 * alloc.c (allocate_vectorlike):
18862 Check for overflow in vector size calculations.
18863 * ccl.c (ccl_driver):
18864 Check for overflow when converting EMACS_INT to int.
18865 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18866 need to be updated by these changes.
18867 * fns.c (make_hash_table, maybe_resize_hash_table):
18868 Check for integer overflow with large hash tables.
18869 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18870 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18871 (SXHASH_REDUCE): New macro.
18872 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18873 Use it instead of discarding useful hash info with large hash values.
18874 (sxhash_float): New function.
18875 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18876 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18877 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18878 Rewrite to use FIXNUM_BITS, as this simplifies things.
18879 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18880 Adjust signatures to match updated version of code.
18881 (consing_since_gc): Now EMACS_INT, since a single hash table can
18882 use more than INT_MAX bytes.
18884 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18886 Make it possible to build with GCC-4.6+ -O2 -flto.
18888 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18890 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18892 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18893 Call minibuffer-inactive-mode.
18895 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18897 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18898 Update dependencies.
18900 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18902 * data.c (init_data): Remove code for UTS, this system is not
18905 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18907 Don't force ./temacs to start in terminal mode.
18909 * frame.c (make_initial_frame): Initialize faces in all cases, not
18910 only when CANNOT_DUMP is defined.
18911 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18913 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18915 * dispnew.c (add_window_display_history): Use const for the string
18916 pointer. Remove declaration, not needed.
18918 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18920 Use 'inline', not 'INLINE'.
18921 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18922 * alloc.c, fontset.c (INLINE): Remove.
18923 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18924 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18925 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18926 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18927 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18929 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18931 Make it possible to run ./temacs.
18933 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18934 syms_of_callproc does the same thing. Remove test for
18935 "initialized", do it in the caller.
18936 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18938 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18940 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18941 (read_minibuf): Use get_minibuffer.
18942 (syms_of_minibuf): Use DEFSYM.
18943 (Qmetadata): New var.
18944 * data.c (Qbuffer): Don't make it static.
18945 (syms_of_data): Use DEFSYM.
18947 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18949 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18950 (CCL_CODE_MIN): New macro.
18952 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18954 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18956 * eval.c (Qdebug): Now static.
18957 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18958 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18959 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18961 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18963 * image.c: Various fixes to ImageMagick code comments.
18964 (Fimagemagick_types): Doc fix.
18966 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18968 Minor fixes prompted by GCC 4.6.0 warnings.
18970 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18972 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18973 (x_clipboard_manager_save_all): Move extern decl to ...
18974 * xterm.h: ... here, so that it can be checked for consistency.
18976 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18978 * xselect.c (x_clipboard_manager_save_frame)
18979 (x_clipboard_manager_save_all): New functions.
18980 (Fx_clipboard_manager_save): Lisp function deleted.
18982 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18983 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18985 * xterm.h: Update prototype.
18987 2011-05-28 William Xu <william.xwl@gmail.com>
18989 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18990 exiting (Bug#8239).
18992 2011-05-28 Jim Meyering <meyering@redhat.com>
18994 Avoid a sign-extension bug in crypto_hash_function.
18995 * fns.c (to_uchar): Define.
18996 (crypto_hash_function): Use it to convert some newly-signed
18997 variables to unsigned, to avoid sign-extension bugs. For example,
18998 without this change, (md5 "truc") would evaluate to
18999 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19000 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19001 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19003 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19005 Integer overflow fixes.
19007 * dbusbind.c: Serial number integer overflow fixes.
19008 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19009 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19010 to hold a serial number that is too large for a fixnum.
19011 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19012 Check for serial numbers out of range. Decode any serial number
19013 that was so large that it became a float. (Bug#8722)
19015 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19016 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19017 Use XFASTINT rather than XUINT when numbers are nonnegative.
19018 (xd_append_arg, Fdbus_method_return_internal):
19019 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19020 arguments, check that Lisp number is nonnegative, rather than
19021 silently wrapping negative numbers around. (Bug#8722)
19022 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19025 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19027 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19029 ccl: Add integer overflow checks.
19030 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19031 (IN_INT_RANGE): New macros.
19032 (ccl_driver): Use them to check for integer overflow when
19033 decoding a CCL program. Many of the new checks are whether XINT (x)
19034 fits in int; it doesn't always, on 64-bit hosts. The new version
19035 doesn't catch all possible integer overflows, but it's an
19036 improvement. (Bug#8719)
19038 * alloc.c (make_event_array): Use XINT, not XUINT.
19039 There's no need for unsigned here.
19041 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19042 This follows up to the 2011-05-06 change that substituted uintptr_t
19043 for EMACS_INT. This case wasn't caught back then.
19045 Rework Fformat to avoid integer overflow issues.
19046 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19047 now (part of C89). Include <verify.h>.
19048 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19049 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19050 (Fformat): Avoid the prepass trying to compute sizes; it was only
19051 approximate and thus did not catch overflow reliably. Instead, walk
19052 through the format just once, formatting and computing sizes as we go,
19053 checking for integer overflow at every step, and allocating a larger
19054 buffer as needed. Keep track separately whether the format is
19055 multibyte. Keep only the most-recently calculated precision, rather
19056 than them all. Record whether each argument has been converted to
19057 string. Use EMACS_INT, not int, for byte and char and arg counts.
19058 Support field widths and precisions larger than INT_MAX. Avoid
19059 sprintf's undefined behavior with conversion specifications such as %#d
19060 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19061 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19062 formatting out-of-range floating point numbers with int
19063 formats. (Bug#8668)
19065 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19067 * data.c: Avoid integer truncation in expressions involving floats.
19068 * data.c: Include <intprops.h>.
19069 (arith_driver): When there's an integer overflow in an expression
19070 involving floating point, convert the integers to floating point
19071 so that the resulting value does not suffer from catastrophic
19072 integer truncation. For example, on a 64-bit host (* 4
19073 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19074 Do not rely on undefined behavior after integer overflow.
19076 merge count_size_as_multibyte, parse_str_to_multibyte
19077 * character.c, character.h (count_size_as_multibyte):
19078 Rename from parse_str_to_multibyte; all uses changed.
19079 Check for integer overflow.
19080 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19081 since it's now a duplicate of the other. This is more of
19082 a character than a buffer op, so better that it's in character.c.
19083 * fns.c, print.c: Adjust to above changes.
19085 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19087 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19089 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19091 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19092 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19093 (x_clipboard_manager_save): Now static.
19094 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19096 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19097 (crypto_hash_function): Now static.
19098 Fix pointer signedness problems. Avoid unnecessary initializations.
19100 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19102 * termhooks.h (Vselection_alist): Make it terminal-local.
19104 * terminal.c (create_terminal): Initialize it.
19106 * xselect.c: Support for clipboard managers.
19107 (Vselection_alist): Move to termhooks.h as terminal-local var.
19108 (LOCAL_SELECTION): New macro.
19109 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19110 (symbol_to_x_atom): Remove gratuitous arg.
19111 (x_handle_selection_request, lisp_data_to_selection_data)
19112 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19113 (x_own_selection, x_get_local_selection, x_convert_selection):
19114 New arg, specifying work frame. Use terminal-local Vselection_alist.
19115 (some_frame_on_display): Delete unused function.
19116 (Fx_own_selection_internal, Fx_get_selection_internal)
19117 (Fx_disown_selection_internal, Fx_selection_owner_p)
19118 (Fx_selection_exists_p): New optional frame arg.
19119 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19120 (x_handle_selection_clear): Don't treat other terminals with the
19121 same keyboard specially. Use the terminal-local Vselection_alist.
19122 (x_clear_frame_selections): Use Frun_hook_with_args.
19124 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19126 * xterm.h: Add support for those atoms.
19128 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19130 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19131 (converted_selections, conversion_fail_tag): New global variables.
19132 (x_selection_request_lisp_error): Free the above.
19133 (x_get_local_selection): Remove unnecessary code.
19134 (x_reply_selection_request): Args changed; handle arbitrary array
19135 of converted selections stored in converted_selections.
19136 Separate the XChangeProperty and SelectionNotify steps.
19137 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19138 (x_convert_selection): New function.
19139 (x_handle_selection_event): Simplify.
19140 (x_get_foreign_selection): Don't ignore incoming requests while
19141 waiting for an answer; this will fail when we implement
19142 SAVE_TARGETS, and seems unnecessary anyway.
19143 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19144 (Vx_sent_selection_functions): Doc fix.
19146 2011-05-26 Leo Liu <sdl.web@gmail.com>
19148 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19150 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19152 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19154 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19155 for fringe update if it has periodic bitmap.
19156 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19157 and fringe_bitmap_periodic_p.
19159 * fringe.c (get_fringe_bitmap_data): New function.
19160 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19161 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19162 row. Mark glyph row for fringe update if periodicity changed.
19164 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19165 for fringe update unless it has periodic bitmap.
19167 2011-05-25 Kenichi Handa <handa@m17n.org>
19169 * xdisp.c (get_next_display_element): Set correct it->face_id for
19170 a static composition.
19172 2011-05-24 Leo Liu <sdl.web@gmail.com>
19175 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19177 * fns.c (crypto_hash_function, Fsha1): New function.
19178 (Fmd5): Use crypto_hash_function.
19179 (syms_of_fns): Add Ssha1.
19181 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19183 * gnutls.c: Remove unused macros.
19184 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19185 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19186 Remove macros that are defined and never used.
19187 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19189 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19191 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19192 (Fx_get_selection_internal): Minor cleanup.
19193 (Fx_own_selection_internal): Rename arguments for consistency with
19196 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19198 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19200 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19202 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19204 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19206 * dispnew.c (scrolling_window): Don't exclude the case that the
19207 last enabled row in the desired matrix touches the bottom boundary.
19209 2011-05-21 Glenn Morris <rgm@gnu.org>
19211 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19212 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19213 and add some more files.
19215 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19217 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19218 report_file_error introduced by the change from 2011-05-07.
19220 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19222 * systime.h (Time): Define only if emacs is defined.
19223 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19224 where the include path doesn't have X11/X.h by default. See
19225 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19227 2011-05-20 Kenichi Handa <handa@m17n.org>
19229 * composite.c (find_automatic_composition): Fix previous change.
19231 2011-05-20 Glenn Morris <rgm@gnu.org>
19233 * lisp.mk: New file, split from Makefile.in.
19234 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19235 (shortlisp): Remove.
19236 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19238 2011-05-19 Glenn Morris <rgm@gnu.org>
19240 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19241 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19242 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19243 (lisp): Set the order to that of loadup.el.
19244 (shortlisp): Make it a copy of $lisp.
19245 (SOME_MACHINE_LISP): Remove.
19246 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19247 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19249 2011-05-18 Kenichi Handa <handa@m17n.org>
19251 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19252 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19253 (find_automatic_composition): Mostly rewrite for efficiency.
19255 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19257 * makefile.w32-in: Update dependencies.
19259 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19261 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19262 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19264 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19266 Fix some integer overflow issues, such as string length overflow.
19268 * insdel.c (count_size_as_multibyte): Check for string overflow.
19270 * character.c (lisp_string_width): Check for string overflow.
19271 Use EMACS_INT, not int, for string indexes and lengths; in
19272 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19273 the resulting string length overflows an EMACS_INT; instead,
19274 report a string overflow if no precision given. When checking for
19275 precision exhaustion, use a check that cannot possibly have
19276 integer overflow. (Bug#8675)
19277 * character.h (lisp_string_width): Adjust to new signature.
19279 * alloc.c (string_overflow): New function.
19280 (Fmake_string): Use it. This doesn't change behavior, but saves
19281 a few bytes and will simplify future changes.
19282 * character.c (string_escape_byte8): Likewise.
19283 * lisp.h (string_overflow): New decl.
19285 Fixups, following up to the user-interface timestamp change.
19286 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19287 for UI timestamps, instead of unsigned long.
19288 * msdos.c (mouse_get_pos): Likewise.
19289 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19290 * w32gui.h (Time): Define by including "systime.h" rather than by
19291 declaring it ourselves. (Bug#8664)
19293 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19294 * image.c (clear_image_cache): Likewise.
19296 * term.c (term_mouse_position): Don't assume time_t wraparound.
19298 Be more systematic about user-interface timestamps.
19299 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19300 and sometimes 'EMACS_UINT', to represent these timestamps.
19301 This change causes it to use 'Time' uniformly, as that's what X uses.
19302 This makes the code easier to follow, and makes it easier to catch
19303 integer overflow bugs such as Bug#8664.
19304 * frame.c (Fmouse_position, Fmouse_pixel_position):
19305 Use Time, not unsigned long, for user-interface timestamps.
19306 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19307 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19308 * keyboard.h (last_event_timestamp): Likewise.
19309 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19310 * menu.h (xmenu_show): Likewise.
19311 * term.c (term_mouse_position): Likewise.
19312 * termhooks.h (struct input_event.timestamp): Likewise.
19313 (struct terminal.mouse_position_hook): Likewise.
19314 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19315 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19316 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19317 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19318 what it was before.
19319 * menu.h, termhooks.h: Include "systime.h", for Time.
19321 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19322 Don't assume that the difference between two unsigned long values
19323 can fit into an integer. At this point, we know button_down_time
19324 <= event->timestamp, so the difference must be nonnegative, so
19325 there's no need to cast the result if double-click-time is
19326 nonnegative, as it should be; check that it's nonnegative, just in
19327 case. This bug is triggered when events are more than 2**31 ms
19328 apart (about 25 days). (Bug#8664)
19330 * xselect.c (last_event_timestamp): Remove duplicate decl.
19331 (x_own_selection): Remove needless cast to unsigned long.
19333 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19334 that always fit in int. Use a sentinel instead of a counter, to
19335 avoid a temp and to allay GCC's concerns about possible int overflow.
19336 * frame.h (struct frame): Use int for menu_bar_items_used
19337 instead of EMACS_INT, since it always fits in int.
19339 * menu.c (grow_menu_items): Check for int overflow.
19341 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19343 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19344 Before, the code was not consistent. These values cannot exceed
19345 2**31 - 1 so there's no need to make them unsigned.
19346 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19347 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19348 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19350 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19352 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19353 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19354 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19355 presumably because the widths might not match.
19357 * window.c (size_window): Avoid needless test at loop start.
19359 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19361 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19363 2011-05-12 Drew Adams <drew.adams@oracle.com>
19365 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19367 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19369 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19370 `width' to `bar_area_x' and `bar_area_width', respectively.
19371 (x_scroll_run): Take account of fringe background extension.
19373 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19374 Rename local vars `left' and `width' to `bar_area_x' and
19375 `bar_area_width', respectively.
19376 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19377 background extension.
19379 2011-05-10 Jim Meyering <meyering@redhat.com>
19381 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19383 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19385 * image.c (Finit_image_library): Return t for built-in image types,
19386 like pbm and xbm. (Bug#8640)
19388 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19390 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19392 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19394 * w32console.c (Fset_screen_color): Doc fix.
19395 (Fget_screen_color): New function.
19396 (syms_of_ntterm): Defsubr it.
19398 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19399 unlink the temporary file if Fcall_process didn't create it in the
19401 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19402 child process will be redirected to a file specified with `:file'.
19403 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19404 cue to call_process_cleanup not to close that handle.
19406 2011-05-07 Ben Key <bkey76@gmail.com>
19408 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19409 one of two shell specific rules, either bootstrap-temacs-CMD or
19410 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19411 to the previous implementation of the bootstrap-temacs rule.
19412 The bootstrap-temacs-CMD rule is similar to the previous
19413 implementation of the bootstrap-temacs rule except that it
19414 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19417 These changes, along with some changes to nt/configure.bat,
19418 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19419 earlier fix to add support for --cflags and --ldflags options
19420 that include quotes so that it works whether make uses cmd or
19423 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19425 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19426 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19428 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19429 a string. Handle both cases.
19430 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19431 (Fdbus_register_method): Use Qinvalid_function.
19433 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19435 * makefile.w32-in: Update dependencies.
19436 (LISP_H): Add inttypes.h and stdin.h.
19437 (PROCESS_H): Add unistd.h.
19439 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19441 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19442 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19444 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19446 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19448 * term.c (vfatal): Remove stray call to va_end.
19449 It's not needed and the C Standard doesn't allow it here anyway.
19451 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19452 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19454 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19457 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19459 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19461 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19463 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19465 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19467 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19468 * charset.c (Fdefine_charset_internal): Don't initialize
19469 charset.code_space[15]. The value was garbage, on hosts with
19470 32-bit int (Bug#8600).
19472 * lread.c (read_integer): Be more consistent with string-to-number.
19473 Use string_to_number to do the actual conversion; this avoids
19474 rounding errors and fixes some other screwups. Without this fix,
19475 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19476 (digit_to_number): Move earlier, for benefit of read_integer.
19477 Return -1 if the digit is out of range for the base, -2 if it is
19478 not a digit in any supported base. (Bug#8602)
19480 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19482 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19483 to match comment at start of function. This also removes a
19484 GCC warning about overflow in a 32+64-bit port.
19486 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19488 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19489 Reported by Stefan Monnier in
19490 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19491 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19492 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19494 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19495 (EMACS_UINTPTR): Likewise, with uintptr_t.
19497 * lisp.h: Prefer 64-bit EMACS_INT if available.
19498 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19499 on 32-bit hosts that have 64-bit int, so that they can access
19501 However, temporarily disable this change unless the temporary
19502 symbol WIDE_EMACS_INT is defined.
19504 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19506 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19507 This removes an assumption that EMACS_INT and long are the same
19508 width as pointers. The assumption is true for Emacs porting targets
19509 now, but we want to make other targets possible.
19510 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19511 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19512 In the rest of the code, change types of integers that hold casted
19513 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19514 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19515 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19516 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19517 No need to cast type when ORing.
19518 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19519 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19520 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19521 assume EMACS_INT is the same width as char *.
19522 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19523 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19524 Remove no-longer-needed casts.
19525 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19526 (xg_tool_bar_help_callback, xg_make_tool_item):
19527 Use EMACS_INTPTR to hold an integer
19528 that will be cast to void *; this can avoid a GCC warning
19529 if EMACS_INT is not the same width as void *.
19530 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19531 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19532 (current_message_1, set_message_1):
19533 Use a local to convert to proper width without a cast.
19534 * xmenu.c (dialog_selection_callback): Likewise.
19536 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19537 Also, don't assume VALBITS / RAND_BITS is less than 5,
19538 and don't rely on undefined behavior when shifting a 1 left into
19540 * lisp.h (get_random): Change signature to match.
19542 * lread.c (hash_string): Use size_t, not int, for hash computation.
19543 Normally we prefer signed values; but hashing is special, because
19544 it's better to use unsigned division on hash table sizes so that
19545 the remainder is nonnegative. Also, size_t is the natural width
19546 for hashing into memory. The previous code used 'int', which doesn't
19547 retain enough info to hash well into very large tables.
19548 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19550 * dbusbind.c: Don't possibly lose pointer info when converting.
19551 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19552 Use XPNTR rather than XHASH, so that the high-order bits of
19553 the pointer aren't lost when converting through void *.
19555 * eval.c (Fautoload): Don't double-shift a pointer.
19557 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19591 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19592 Remove unused parameter `fildes'.
19593 * process.c (read_process_output, send_process): Don't pass it.
19595 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19597 Fix previous change: the library cache is defined in w32.c.
19598 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19599 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

19634 (w32_delayed_load): Move from image.c. When loading a library, record
19635 its filename in the :loaded-from property of the library id.

19637 Initialize and staticpro them.
19638 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19640 * process.c: Include lisp.h before w32.h, not after.
19641 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19642 instead of gnutls_record_check_pending.
19644 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19646 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19648 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19649 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19652 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19654 * xterm.c (x_set_frame_alpha): Do not set property on anything
19655 else than FRAME_X_OUTER_WINDOW (Bug#8608).

19659 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19661 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19663 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

19689 (Fcall_process_region): Ditto.
19691 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19693 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19694 rather than `XVECTOR (FOO)->size'.
19696 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19697 inttypes.h, as a gnulib replacement is used if it not available in
19700 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19702 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19703 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19704 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19706 * coding.c (coding_alloc_by_realloc): Error out if destination
19707 will grow beyond MOST_POSITIVE_FIXNUM.
19708 (decode_coding_emacs_mule): Abort if there isn't enough place in
19709 charbuf for the composition carryover bytes. Reserve an extra
19710 space for up to 2 characters produced in a loop.

19712 charbuf for the composition carryover bytes.
19714 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19716 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19717 aborting when %lld or %lll format is passed.
19718 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19719 %llo or %llx format is passed. (Bug#8545)
19721 * window.c (window_scroll_line_based): Use a marker instead of
19722 simple variables to record original value of point. (Bug#7952)
19724 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19725 produced by %s or %c overflows available buffer space. (Bug#8545)
19727 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19729 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19732 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

19738 * keyboard.c (Qdelayed_warnings_hook): Define.
19739 (command_loop_1): Run `delayed-warnings-hook'
19740 if Vdelayed_warnings_list is non-nil.
19741 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19742 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19744 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19746 * doprnt.c (doprnt): Don't return value smaller than the buffer
19747 size if the message was truncated. (Bug#8545).
19749 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19751 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

19758 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19760 * makefile.w32-in: Update dependencies.
19762 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19764 Improve `doprnt' and its usage. (Bug#8545)
19765 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19766 `format_end'. Remove support for %l as a conversion specifier.
19767 Don't use xrealloc. Improve diagnostics when the %l size modifier
19768 is used. Update the commentary.
19770 * eval.c (verror): Simplify calculation of size_t.
19772 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19775 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19777 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19780 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19782 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19783 This makes this file independent of the recent pseudovector change.
19785 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19787 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19789 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19790 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19791 Remove unused local.
19792 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19794 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19795 GCC 4.6.0 optimizes based on type-based alias analysis.
19796 For example, if b is of type struct buffer * and v of type struct
19797 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19798 != &v->size, and therefore "v->size = 1; b->size = 2; return
19799 v->size;" must therefore return 1. This assumption is incorrect
19800 for Emacs, since it type-puns struct Lisp_Vector * with many other
19801 types. To fix this problem, this patch adds a new type struct
19802 vectorlike_header that documents the constraints on layout of vectors
19803 and pseudovectors, and helps optimizing compilers not get fooled
19804 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19805 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19806 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19808 (XSETPVECTYPE): Rewrite in terms of new macro.
19809 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19810 This is a bit clearer, and further avoids the possibility of
19811 undesirable aliasing.
19812 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19813 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19814 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19815 since Lisp_Subr is a special case (no "next" field).
19816 (ASIZE): Now uses header.size rather than size.
19817 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19818 to avoid the hassle of writing XVECTOR (foo)->header.size.
19819 (struct vectorlike_header): New type.
19820 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19821 object, to help avoid aliasing.
19822 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19823 (SUBRP): Likewise, since Lisp_Subr is a special case.
19824 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19825 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19826 (struct Lisp_Hash_Table): Combine first two members into a single
19827 struct vectorlike_header member. All uses of "size" and "next" members
19828 changed to be "header.size" and "header.next".
19829 * buffer.h (struct buffer): Likewise.
19830 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19831 * frame.h (struct frame): Likewise.
19832 * process.h (struct Lisp_Process): Likewise.
19833 * termhooks.h (struct terminal): Likewise.
19834 * window.c (struct save_window_data, struct saved_window): Likewise.
19835 * window.h (struct window): Likewise.
19836 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19837 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19838 * buffer.c (init_buffer_once): Likewise.
19839 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19841 * process.c (Fformat_network_address): Use local var for size,
19844 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19846 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19847 * data.c (atof): Remove decl; no longer used or needed.
19848 (digit_to_number): Move to lread.c.
19849 (Fstring_to_number): Use new string_to_number function, to be
19850 consistent with how the Lisp reader treats infinities and NaNs.
19851 Do not assume that floating-point numbers represent EMACS_INT
19852 without losing information; this is not true on most 64-bit hosts.
19853 Avoid double-rounding errors, by insisting on integers when
19854 parsing non-base-10 numbers, as the documentation specifies.
19855 * lisp.h (string_to_number): New decl, replacing ...
19856 (isfloat_string): Remove.
19857 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19858 (read1): Do not accept +. and -. as integers; this
19859 appears to have been a coding error. Similarly, do not accept
19860 strings like +-1e0 as floating point numbers. Do not report
19861 overflow for integer overflows unless the base is not 10 which
19862 means we have no simple and reliable way to continue.
19863 Break out the floating-point parsing into a new
19864 function string_to_number, so that Fstring_to_number parses
19865 floating point numbers consistently with the Lisp reader.
19866 (digit_to_number): Move here from data.c. Make it static inline.
19867 (E_CHAR, EXP_INT): Remove, replacing with ...
19868 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19869 (string_to_number): New function, replacing isfloat_string.
19870 This function checks for valid syntax and produces the resulting
19871 Lisp float number too. Rework it so that string-to-number
19872 no longer mishandles examples like "1.0e+". Use strtoumax,
19873 so that overflow for non-base-10 numbers is reported only when
19874 there's no portable and simple way to convert to floating point.
19876 * textprop.c (set_text_properties_1): Rewrite for clarity,
19877 and to avoid GCC warning about integer overflow.
19879 * intervals.h (struct interval): Use EMACS_INT for members
19880 where EMACS_UINT might cause problems. See
19881 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19882 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19883 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19885 (offset_intervals): Tell GCC not to worry about length overflow
19886 when negating a negative length.
19888 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19889 (overrun_check_free): Likewise.
19891 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19892 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19895 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19896 (gnutls_make_error): Rename local to avoid shadowing.
19897 (gnutls_emacs_global_deinit): ifdef out; not used.
19898 (Fgnutls_boot): Use const for pointer to readonly storage.
19899 Comment out unused local. Fix pointer signedness problems.
19901 * lread.c (openp): Don't stuff size_t into an 'int'.
19902 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19903 about possible signed overflow.
19905 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19906 (GDK_KEY_g): Don't define if already defined.
19907 (xg_prepare_tooltip): Avoid pointer signedness problem.
19908 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19910 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19911 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19913 * xfns.c (Fx_window_property): Simplify a bit,
19914 to make a bit faster and to avoid GCC 4.6.0 warning.
19915 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19917 * fns.c (internal_equal): Don't assume size_t fits in int.
19919 * alloc.c (compact_small_strings): Tighten assertion a little.
19921 Replace pEd with more-general pI, and fix some printf arg casts.
19922 * lisp.h (pI): New macro, generalizing old pEd macro to other
19923 conversion specifiers. For example, use "...%"pI"d..." rather
19924 than "...%"pEd"...".
19925 (pEd): Remove. All uses replaced with similar uses of pI.
19926 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19927 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19928 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19929 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19930 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19931 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19932 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19934 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19935 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19936 * print.c (safe_debug_print, print_object): Likewise.
19937 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19939 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19940 avoiding the 0 flag, which is not portable.
19941 * process.c (Fmake_network_process): Use pI to avoid cast.
19942 * region-cache.c (pp_cache): Likewise.
19943 * xdisp.c (decode_mode_spec): Likewise.
19944 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19945 behavior on 64-bit hosts with printf arg.
19946 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19947 (x_stop_queuing_selection_requests): Likewise.
19948 (x_get_window_property): Don't truncate byte count to an 'int'
19951 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19952 here, since it parses constructs like leading '-' and spaces,
19953 which are not wanted; and it overflows with large numbers.
19954 Instead, simply match F[0-9]+, which is what is wanted anyway.

19960 plus offsetof, to remove unportable assumptions about struct layout.
19961 These assumptions hold on all porting targets that I know of, but
19962 they are not guaranteed, they're easy to remove, and removing them
19963 makes further changes easier.
19965 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19966 This doesn't fix a bug but makes the code clearer.
19967 (string_overrun_cookie): Now const. Use initializers that

19970 can cause Emacs to crash when string overrun checking is enabled.
19971 (allocate_buffer): Don't assume sizeof (struct buffer) is a

20010 supported by the function. Use SAFE_ALLOCA instead of always
20013 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20014 is one byte too soon. Don't use xrealloc; instead xfree and

20141 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20142 to `error' in error message about FINAL_CHAR argument. Make sure
20143 FINAL_CHAR is a character, and use %c when it is passed as
20144 argument to `error'.
20146 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20148 * s/ms-w32.h (localtime): Redirect to sys_localtime.

20214 * dispextern.h (struct redisplay_interface): Rename param
20215 to avoid shadowing.

20334 ns_descriptor_to_entity that were caused by using free to
20335 deallocate memory blocks that were allocated by xmalloc (via

20356 (emacs_read, emacs_write): Use it.
20357 * process.c (send_process): Adjust to the new signatures of
20358 emacs_write and emacs_gnutls_write. Do not attempt to store

20844 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20846 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20847 argument, local variables, and return value.
20849 * lisp.h: Update prototypes of emacs_write and emacs_read.
20851 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20853 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20855 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20857 Fix more problems found by GCC 4.6.0's static checks.
20859 * xdisp.c (vmessage): Use a better test for character truncation.
20861 * charset.c (load_charset_map): <, not <=, for optimization,
20862 and to avoid potential problems with integer overflow.
20863 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20864 * casetab.c (set_identity, shuffle): Likewise.
20865 * editfns.c (Fformat): Likewise.
20866 * syntax.c (skip_chars): Likewise.
20868 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20869 This also lets GCC 4.6.0 generate slightly better loop code.
20871 * callint.c (Fcall_interactively): <, not <=, for optimization.
20872 (Fcall_interactively): Count the number of arguments produced,
20873 not the number of arguments given. This is simpler and lets GCC
20874 4.6.0 generate slightly better code.
20876 * ftfont.c: Distingish more carefully between FcChar8 and char.
20877 The previous code passed unsigned char * to a functions like
20878 strlen and xstrcasecmp that expect char *, which does not
20879 conform to the C standard.
20880 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20881 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20882 char * when the C standard requires it.
20884 * keyboard.c (read_char): Remove unused var.
20886 * eval.c: Port to Windows vsnprintf (Bug#8435).
20887 Include <limits.h>.
20888 (SIZE_MAX): Define if the headers do not.
20889 (verror): Do not give up if vsnprintf returns a negative count.
20890 Instead, grow the buffer. This ports to Windows vsnprintf, which
20891 does not conform to C99. Problem reported by Eli Zaretskii.
20892 Also, simplify the allocation scheme, by avoiding the need for
20893 calling realloc, and removing the ALLOCATED variable.
20895 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20897 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20898 But keep the doprint source code for now, as we might revamp it
20899 and use it again (Bug#8435).
20900 * lisp.h (doprnt): Remove.
20901 * Makefile.in (base_obj): Remove doprnt.o.
20902 * deps.mk (doprnt.o): Remove.
20904 error: Print 32- and 64-bit integers portably (Bug#8435).
20905 Without this change, on typical 64-bit hosts error ("...%d...", N)
20906 was used to print both 32- and 64-bit integers N, which relied on
20907 undefined behavior.
20908 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20909 * lisp.h (error, verror): Mark as printf-like functions.
20910 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20911 Report overflow in size calculations when allocating printf buffer.
20912 Do not truncate output string at its first null byte.
20913 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20914 Truncate the output at a character boundary, since vsnprintf does not
20916 * charset.c (check_iso_charset_parameter): Convert internal
20917 character to string before calling 'error', since %c now has the
20919 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20920 overflow when computing char to be passed to 'error'. Do not
20921 pass Lisp_Object to 'error'; pass the integer instead.
20922 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20923 formatted with plain %d.
20925 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20927 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20929 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20931 * xterm.c (x_catch_errors): Remove duplicate declaration.
20933 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20935 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20937 2011-04-10 Jim Meyering <meyering@redhat.com>
20939 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20940 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20941 return ssize_t not "int", and use size_t as the buffer length.
20942 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20943 * gnutls.h: Update declarations.
20944 * process.c (read_process_output): Use ssize_t, to match.
20945 (send_process): Likewise.
20947 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20949 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20951 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20953 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20954 Use unsigned char, to match FcChar8 type definition.
20956 * xterm.c (handle_one_xevent):
20957 * xmenu.c (create_and_show_popup_menu):
20958 * xselect.c (x_decline_selection_request)
20959 (x_reply_selection_request): Avoid type-punned deref of X events.
20961 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20963 Fix some uses of `int' instead of EMACS_INT.
20964 * search.c (string_match_1, fast_string_match)
20965 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20966 (scan_buffer, find_next_newline_no_quit)
20967 (find_before_next_newline, search_command, Freplace_match)
20968 (Fmatch_data): Make some `int' variables be EMACS_INT.
20970 * xdisp.c (display_count_lines): 3rd argument and return value now
20971 EMACS_INT. All callers changed.
20972 (pint2hrstr): Last argument is now EMACS_INT.
20974 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20975 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20976 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20977 (decode_coding_utf_16, decode_coding_emacs_mule)
20978 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20979 (decode_coding_ccl, decode_coding_charset)
20980 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20981 (decode_coding_iso_2022, decode_coding_emacs_mule)
20982 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20983 <char_offset, last_offset>: Declare EMACS_INT.
20984 (encode_coding_utf_8, encode_coding_utf_16)
20985 (encode_coding_emacs_mule, encode_invocation_designation)
20986 (encode_designation_at_bol, encode_coding_iso_2022)
20987 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20988 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20990 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20991 (encode_invocation_designation): Last argument P_NCHARS is now
20993 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20994 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20996 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20999 * ccl.c (Fccl_execute_on_string): Declare some variables
21002 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21004 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21006 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21008 * process.c (Fformat_network_address): Doc fix.
21010 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21012 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21014 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21016 * keyboard.c (read_char): Call Lisp function help-form-show,
21017 instead of using internal_with_output_to_temp_buffer.
21018 (Qhelp_form_show): New var.
21019 (syms_of_keyboard): Use DEFSYM macro.
21021 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21023 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21025 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

21034 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21036 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21038 Fix more problems found by GCC 4.6.0's static checks.

21042 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21044 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21046 * xdisp.c (vmessage): Mark as a printf-like function.
21048 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21050 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21052 * image.c (tiff_error_handler, tiff_warning_handler): Mark as

21055 to system-supplied API.
21057 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21059 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21060 This avoids several warnings with gcc -Wstrict-overflow.
21061 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21062 directly, rather than having caller test rule sign. This avoids
21063 some unnecessary tests.
21064 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21065 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21066 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21068 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21069 (xfont_open): Avoid unnecessary tests.
21071 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21073 * composite.h, composite.c (composition_gstring_put_cache):
21074 Use EMACS_INT, not int, for length.

21080 by using the new macro.
21082 * textprop.c (set_text_properties_1): Change while to do-while,
21083 since the condition is always true at first.
21085 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21086 (interval_deletion_adjustment): Return unsigned value.
21089 * process.c (list_processes_1, create_pty, read_process_output):

21101 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21102 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21103 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21105 * print.c (print_error_message): Avoid int overflow.
21107 * font.c (font_list_entities): Redo for clarity,
21108 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21110 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21111 (font_score): Avoid potential overflow in diff calculation.
21113 * fns.c (substring_both): Remove var that is set but not used.
21114 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21116 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21118 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21119 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21120 can always succeed if overflow has undefined behavior.
21122 * search.c (boyer_moore, wordify): Remove vars set but not used.
21123 (wordify): Omit three unnecessary tests.
21125 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21126 All callers changed. This avoids the need for an unused var.

21140 * buffer.c (Fprevious_overlay_change): Remove var that is set
21143 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21144 Remove vars that are set but not used.
21145 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

21148 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21150 * image.c (lookup_image): Remove var that is set but not used.
21151 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21153 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21154 that are set but not used.
21156 * xfns.c (make_invisible_cursor): Don't return garbage
21157 if XCreateBitmapFromData fails (Bug#8410).
21159 * xselect.c (x_get_local_selection, x_handle_property_notify):
21160 Remove vars that are set but not used.

21180 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21181 (decode_coding_charset): Remove vars that are set but not used.
21183 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21184 that is set but not used.
21186 * print.c (print_object): Remove var that is set but not used.
21188 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21189 The gnulib version avoids calling malloc in the usual case,
21190 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21191 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21192 * filelock.c (current_lock_owner): Likewise.

21198 ../lib/careadlinkat.h.
21200 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21202 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21203 first non-nil return value).

21219 (get_per_char_metric): Remove parameter `f', unused since
21220 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21304 (redisplay_window): Even when falling back on "recentering",
21305 position point in the window according to scroll-conservatively,
21306 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21308 (try_scrolling): When point is above the window, allow searching
21309 as far as scroll_max, or one screenful, to compute vertical
21310 distance from PT to the scroll margin position. This prevents
21311 try_scrolling from unnecessarily failing when
21312 scroll-conservatively is set to a value slightly larger than the
21313 window height. Clean up the case of PT below the margin at bottom
21314 of window: scroll_max can no longer be INT_MAX. When aggressive
21315 scrolling is in use, don't let point enter the opposite scroll
21316 margin as result of the scroll.
21317 (syms_of_xdisp) <scroll-conservatively>: Document the
21318 threshold of 100 lines for never-recentering scrolling.
21320 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21322 * dispextern.h (move_it_by_lines):
21323 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21324 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21325 (message_log_check_duplicate): Remove parameters `prev_bol' and
21326 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21327 (redisplay_internal): Remove parameter `preserve_echo_area',
21328 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21330 * indent.c (Fvertical_motion):
21331 * window.c (window_scroll_pixel_based, Frecenter):
21332 Don't pass `need_y_p' to `move_it_by_lines'.
21334 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21336 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21337 steal a few bits to be more compact.
21338 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21339 Remove unneeded casts.
21341 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21343 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21345 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21346 binding" message (bug#7967).
21348 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21350 Fix more problems found by GCC 4.6.0's static checks.
21352 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21353 Remove unused local var.
21355 * editfns.c (Fmessage_box): Remove unused local var.
21357 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21358 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21359 Omit unused local vars.
21360 * window.c (shrink_windows): Omit unused local var.
21361 * menu.c (digest_single_submenu): Omit unused local var.
21362 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21363 Omit unused local var.
21365 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21366 Don't assume string length fits in int.
21367 (keyremap_step, read_key_sequence): Use size_t for sizes.
21368 (read_key_sequence): Don't check last_real_key_start redundantly.
21370 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21371 instead of alloca (Bug#8344).
21373 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21374 (Fbacktrace_frame): Don't assume nframes fits in int.
21376 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21378 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21381 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21383 * cm.c (calccost): Turn while-do into do-while, for clarity.
21385 * keyboard.c (syms_of_keyboard): Use the same style as later
21386 in this function when indexing through an array. This also
21387 works around GCC bug 48267.
21389 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21391 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21393 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21394 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21396 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21397 This avoids undefined behavior on integer overflow, and is a bit
21398 more convenient anyway since it is compared to a size_t variable.
21400 Variadic C functions now count arguments with size_t, not int.
21401 This avoids an unnecessary limitation on 64-bit machines, which
21402 caused (substring ...) to crash on large vectors (Bug#8344).
21403 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21404 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21410 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21411 (funcall_lambda, mark_backtrace): Likewise.
21412 * fns.c (concat): Likewise.
21413 * frame.c (x_set_frame_parameters): Likewise.
21414 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21415 0 if not found, not -1. All callers changed.
21417 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21418 (stack_copy_size): Now size_t, not int.
21419 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21421 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21423 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21424 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21425 All callers changed.
21427 * lisp.h (multibyte_char_to_unibyte):
21428 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21429 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21431 * cmds.c (internal_self_insert):
21432 * editfns.c (general_insert_function):
21433 * keymap.c (push_key_description):
21434 * search.c (Freplace_match):
21435 * xdisp.c (message_dolog, set_message_1): All callers changed.
21437 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21439 * keyboard.c (safe_run_hook_funcall): New function.
21440 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21441 don't set the hook to nil, but remove the offending function instead.
21442 (Qcommand_hook_internal): Remove, unused.
21443 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21444 Vcommand_hook_internal.
21446 * eval.c (enum run_hooks_condition): Remove.
21447 (funcall_nil, funcall_not): New functions.
21448 (run_hook_with_args): Call each function through a `funcall' argument.
21449 Remove `cond' argument, now redundant.
21450 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21451 (Frun_hook_with_args_until_failure): Adjust accordingly.
21452 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21454 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21456 * dispextern.h (string_buffer_position): Remove declaration.
21458 * print.c (strout): Remove parameter `multibyte', unused since
21459 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21461 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21462 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21463 All callers changed.
21465 * w32.c (_wsa_errlist): Use braces for struct initializers.
21467 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21468 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21469 All callers changed.
21470 (string_buffer_position): Likewise. Also, make static (it's never
21471 used outside xdisp.c).

21475 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21476 All callers changed.
21478 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21480 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21509 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21511 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21513 * w32.c (read_unc_volume): Use parameter `henum', instead of
21514 global variable `wget_enum_handle'.
21516 * keymap.c (describe_vector): Remove parameters `indices' and
21517 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21529 * xmenu.c (show_help_event, menu_help_callback):
21530 Adjust calls to `show_help_echo'.
21532 * gtkutil.c (xg_maybe_add_timer):
21533 * keyboard.c (readable_events):
21534 * process.c (wait_reading_process_output):
21535 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21537 * insdel.c (adjust_markers_gap_motion):
21538 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21612 2011-03-23 Julien Danjou <julien@danjou.info>
21614 * term.c (Fsuspend_tty, Fresume_tty):
21615 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21616 * window.c (temp_output_buffer_show):

21623 * callint.c (Fcall_interactively):
21624 * buffer.c (Fkill_all_local_variables):
21625 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21627 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21628 unconditionally since it does the check itself.
21630 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21632 Fix more problems found by GCC 4.5.2's static checks.
21634 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21635 the first time through the loop, since we know p0 < p1 then.
21636 This also avoids a gcc -Wstrict-overflow warning.
21638 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21639 leading to a memory leak, possible in functions like
21640 load_charset_map_from_file that can allocate an unbounded number
21641 of objects (Bug#8318).
21643 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21644 that could (at least in theory) be that large.
21646 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21647 This is less likely to overflow, and avoids undefined behavior if
21648 overflow does occur. All callers changed. Use strtoul to scan
21649 for the unsigned long integer.
21650 (pint2hrstr): Simplify and tune code slightly.
21651 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21653 * scroll.c (do_scrolling): Work around GCC bug 48228.
21654 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21656 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21657 This also avoids a warning with gcc -Wstrict-overflow.
21658 (validate_x_resource_name): Simplify count usage.
21659 This also avoids a warning with gcc -Wstrict-overflow.
21661 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21664 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21666 * process.c (Fmake_network_process): Use socklen_t, not int,
21667 where POSIX says socklen_t is required in portable programs.
21668 This fixes a porting bug on hosts like 64-bit HP-UX, where
21669 socklen_t is wider than int (Bug#8277).
21670 (Fmake_network_process, server_accept_connection):
21671 (wait_reading_process_output, read_process_output):
21674 * process.c: Rename or move locals to avoid shadowing.

21676 (read_process_output_error_handler, exec_sentinel_error_handler):
21677 Rename or move locals.
21678 (Fmake_network_process): Define label "retry_connect" only if needed.
21679 (Fnetwork_interface_info): Fix pointer signedness.
21680 (process_send_signal): Add cast to avoid pointer signedness problem.
21681 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21682 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21684 Make tparam.h and terminfo.c consistent.
21685 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21686 Include tparam.h instead, since it declares them.
21687 * cm.h (PC): Remove extern decl; tparam.h now does this.
21688 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21689 * terminfo.c: Include tparam.h, to check interfaces.
21690 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21691 (tparam): Adjust signature to match interface in tparam.h;
21692 this removes some undefined behavior. Check that outstring and len
21693 are zero, which they always are with Emacs.
21694 * tparam.h (PC, BC, UP): New extern decls.
21696 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21697 (xftfont_open): Rename locals to avoid shadowing.
21699 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21700 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21701 (OTF_TAG_SYM): Omit macro if not needed.
21702 (ftfont_list): Remove unused local.
21703 (get_adstyle_property, ftfont_pattern_entity):
21704 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21705 Rename locals to avoid shadowing.
21707 * xfont.c (xfont_list_family): Mark var as initialized.
21709 * xml.c (make_dom): Now static.
21711 * composite.c (composition_compute_stop_pos): Rename local to
21713 (composition_reseat_it): Remove unused locals.
21714 (find_automatic_composition, composition_adjust_point): Likewise.
21715 (composition_update_it): Mark var as initialized.
21716 (find_automatic_composition): Mark vars as initialized,
21717 with a FIXME (Bug#8290).
21719 character.h: Rename locals to avoid shadowing.
21720 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21721 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21722 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21723 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21724 to avoid shadowing.
21726 * textprop.c (property_change_between_p): Remove; unused.
21728 * intervals.c (interval_start_pos): Now static.
21730 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21732 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21733 Rename locals to avoid shadowing.
21735 * sound.c (wav_play, au_play, Fplay_sound_internal):
21736 Fix pointer signedness.

21743 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21745 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21746 clobbering (Bug#8298).
21747 * sysdep.c (sys_subshell): Likewise.
21748 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21750 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21751 This should get cleaned up, so that child_setup has the
21752 same signature on all platforms.
21754 * callproc.c (call_process_cleanup): Now static.
21755 (relocate_fd): Rename locals to avoid shadowing.
21757 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21885 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21886 some of which prompt warnings from gcc -Wbad-function-cast.
21887 (Fformat_time_string, Fencode_time, Finsert_char):

21916 (Fmemory_limit): Cast sbrk's returned value to char *.
21918 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21921 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21923 Use functions, not macros, for up- and down-casing (Bug#8254).
21924 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21925 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21926 to use the following functions instead of these macros.
21927 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21928 EMACS_INT, since callers assume the returned value fits in int.
21929 (upcase1): Likewise, for UPCASE_TABLE.
21930 (uppercasep, lowercasep, upcase): New static inline functions.
21931 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21941 (regex_compile, re_match_2_internal): Mark locals as initialized.
21942 (RETALLOC_IF): Define only if needed.
21943 (WORDCHAR_P): Likewise. This one is never needed, but is used
21944 only in a comment talking about a compiler bug, so put inside
21945 the #if 0 of that comment.
21946 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21947 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21973 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21974 New macros, so that the caller can use some names other than
21975 gcpro1, gcpro2, etc.
21976 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21978 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21979 argument, for consistency with GCPRO2_VAR, etc: it is now the
21980 prefix of the variable, not the variable itself. All uses
21982 * dired.c (directory_files_internal, file_name_completion):
21983 Rename locals to avoid shadowing.
21985 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21986 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21987 dired.c's scmp function, had undefined behavior.
21988 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21989 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21990 * buffer.h: ... to here, because these macros use current_buffer,
21991 and the new implementation with inline functions needs to have
21992 current_buffer in scope now, rather than later when the macros
21994 (downcase, upcase1): New static inline functions.
21995 (DOWNCASE, UPCASE1): Reimplement using these functions.
21996 This avoids undefined behavior in expressions like
21997 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21998 from race conditions in accessing the global variables
21999 case_temp1 and case_temp2.
22000 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22001 * lisp.h (case_temp1, case_temp2): Remove their decls.
22002 * character.h (ASCII_CHAR_P): Move from here ...
22003 * lisp.h: ... to here, so that the inline functions mentioned
22004 above can use them.
22006 * dired.c (directory_files_internal_unwind): Now static.
22008 * fileio.c (file_name_as_directory, directory_file_name):

22011 (file_name_as_directory): Use const pointers when appropriate.
22012 (Fexpand_file_name): Likewise. In particular, newdir might
22013 point at constant storage, so make it a const pointer.
22014 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22015 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22017 (Fset_file_times, Finsert_file_contents, auto_save_error):

22022 to avoid shadowing.
22024 * marker.c (bytepos_to_charpos): Remove; unused.
22026 * lisp.h (verify_bytepos, count_markers): New decls,
22027 so that gcc does not warn that these functions aren't declared.
22029 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22030 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22031 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22032 (copy_text): Remove unused local var.
22034 * filelock.c (within_one_second): Now static.
22035 (lock_file_1): Rename local to avoid shadowing.
22037 * buffer.c (fix_overlays_before): Mark locals as initialized.
22038 (fix_start_end_in_overlays): Likewise. This function should be
22039 simplified by using pointers-to-pointers, but that's a different
22041 (switch_to_buffer_1): Now static.
22042 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22043 (report_overlay_modification): Rename locals to avoid shadowing.
22045 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22046 Fix pointer signedness issue.
22047 (sys_subshell): Mark local as volatile if checking for lint,
22048 to suppress a gcc -Wclobbered warning that does not seem to be right.
22049 (MAXPATHLEN): Define only if needed.
22051 * process.c (serial_open, serial_configure): Move decls from here ...
22052 * systty.h: ... to here, so that they can be checked.
22054 * fns.c (get_random, seed_random): Move extern decls from here ...
22055 * lisp.h: ... to here, so that they can be checked.
22057 * sysdep.c (reset_io): Now static.
22058 (wait_for_termination_signal): Remove; unused.
22060 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22063 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22064 (DENSE_TABLE_SIZE): Remove; unused.
22065 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22066 (describe_map_tree):
22067 Rename locals to avoid shadowing.
22069 * keyboard.c: Declare functions static if they are not used elsewhere.

22154 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22155 These macros can no longer be used for assignment.
