19 resources were not orderly released.
21 2013-02-17 Eli Zaretskii <eliz@gnu.org>
23 * xdisp.c (x_draw_vertical_border): For a window that is neither
24 the leftmost nor the rightmost, redraw both the left and the right
25 vertical borders. (Bug#13723)
27 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
29 * xml.c (init_libxml2_functions):
30 * sound.c (sound_warning):

40 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
42 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
43 * frame.c (syms_of_frame): ... to here.
45 2013-02-16 Eli Zaretskii <eliz@gnu.org>
47 * w32.c (sys_chown): Remove unused function.
49 * w32term.c <input_signal_count>: Declare 'volatile'
50 unconditionally. (Bug#9066)
52 * w32.c (set_errno): Reset h_errno and don't set it to any other
53 value. Set errno instead.
54 (check_errno): Reset h_errno.
55 (sys_socket, socket_to_fd, sys_bind, sys_connect)
56 (sys_gethostname, sys_getservbyname, sys_getpeername)

62 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
64 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
66 2013-02-15 Eli Zaretskii <eliz@gnu.org>
68 * keyboard.c (read_char): Fix calculation of auto-save time out
69 when auto-save-timeout is less than 4. (Bug#13720)
71 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

79 (socket_to_fd): Add assertion against indexing fd_info[] with a
80 value that is out of bounds.
81 (sys_accept): If fd is negative, do not set up the child_process
82 structure for reading.
84 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
86 * composite.c (fill_gstring_header): Remove useless prototype.

98 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
100 Fix AIX port (Bug#13650).
101 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
102 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
103 was #undeffed earlier, so it cannot be used as a macro here.
104 Use the constant and not the macro.
106 2013-02-15 Eli Zaretskii <eliz@gnu.org>
108 * w32proc.c (new_child): If no vacant slots are found in
109 child_procs[], make another pass looking for slots whose process
110 has exited or died. (Bug#13546)
112 * w32.c (sys_pipe): When failing due to file descriptors above
113 MAXDESC, set errno to EMFILE.
114 (_sys_read_ahead): Update cp->status when failing to read serial
115 communications input, so that the status doesn't stay at
116 STATUS_READ_IN_PROGRESS. (Bug#13546)
118 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
120 * gtkutil.c (tb_size_cb): New function.
121 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

125 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
128 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
130 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
132 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

140 2013-02-13 Glenn Morris <rgm@gnu.org>
142 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
144 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
146 Improve AIX port some more (Bug#13650).
147 With this, it should be as good as it was in 23.3, though it's
148 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
149 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
150 * unexaix.c (start_of_text): Remove.
151 (_data, _text): Declare as char[], not int, as AIX manual suggests.
152 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
153 (orig_load_scnptr, orig_data_scnptr):
154 Now off_t, not long, since they are file offsets.
155 (make_hdr): Use _data, not start_of_data ().
156 This is the key part of the fix.
157 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
158 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
160 * pre-crt0.c (data_start): Initialize to 1.
161 This ports to compilers that optimize the external declaration
162 'int x = 0;' as if it were 'int x;' to shrink the executable.
164 Improve AIX port (Bug#13650).
165 This doesn't fix the bug, but it makes progress: Emacs builds now.
166 * unexaix.c: Include inttypes.h, stdarg.h.
167 (report_error, report_error_1): Mark as _Noreturn.
168 (report_error): Don't report the wrong errno.
169 (report_error_1): Now varargs. All callers changed.
170 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
171 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
172 (write_ptr): Use %p to print address rather than %lx and a cast
173 to unsigned long. Grow buffer a bit, to be safer.
175 2013-02-13 Eli Zaretskii <eliz@gnu.org>
177 * bidi.c (bidi_resolve_neutral): After finding the next
178 non-neutral character, accept NEUTRAL_ON type as well, because
179 directional control characters, such as LRE and RLE, have their
180 type converted to that by bidi_resolve_weak. This avoids aborts
181 when LRE/RLE follows a run of neutrals.
182 (bidi_move_to_visually_next): Assert that return value of
183 bidi_peek_at_next_level is non-negative. Negative values will
186 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
188 Minor getenv-related fixes.
189 * callproc.c (Fcall_process_region) [!DOS_NT]:
190 Avoid unnecessary duplicate call to getenv.
191 * callproc.c (init_callproc):
192 * dispnew.c (init_display):
193 * sysdep.c (sys_subshell):
194 Omit unnecessary cast of getenv or egetenv.
196 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
198 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
201 2013-02-12 Eli Zaretskii <eliz@gnu.org>
203 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
205 (display_line): Set w->region_showing to the value of
206 it->region_beg_charpos, not to -1. This fixes redisplay
207 optimization when cursor is moved up after M->. (Bug#13623)
209 (try_scrolling): Scroll text up more if point is too close to ZV
210 and inside the scroll margin. This makes sure point is moved
211 outside the scroll margin in these cases.
213 * window.h (struct window): region_showing can no longer be
216 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
218 Tune by using memchr and memrchr.
219 * doc.c (Fsnarf_documentation):
220 * fileio.c (Fsubstitute_in_file_name):
221 * search.c (find_newline, scan_newline):
222 * xdisp.c (pos_visible_p, display_count_lines):
223 Use memchr and memrchr rather than scanning byte-by-byte.
224 * search.c (find_newline): Rename from scan_buffer.
225 Omit first arg TARGET, as it's always '\n'. All callers changed.
227 Clean up read_key_sequence a tiny bit more.
228 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
229 (read_key_sequence): Remove unused locals.
231 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
233 Clean up read_key_sequence a bit; reread active keymaps after first event.
234 * keyboard.c (read_char, read_char_x_menu_prompt)
235 (read_char_minibuf_menu_prompt):
236 Replace nmaps+maps with a single `map' arg.
237 (follow_key): Operate on a single map.
238 (active_maps): New function.
239 (test_undefined): Also return true for nil bindings.
240 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
241 a single (composed) keymap. Remember `first_event' to choose the right
242 set of active keymaps. Recompute the set of keymaps after receiving
243 the first event. Remove GOBBLE_FIRST_EVENT.
244 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
245 * keyboard.h (read_char): Update declaration.
246 * lread.c (read_filtered_event): Adjust call to read_char.
248 2013-02-11 Eli Zaretskii <eliz@gnu.org>
250 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
251 Don't use the limitation on backwards movement when lines are truncated
252 in the window. (Bug#13675)
254 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
256 * marker.c (set_marker_internal): If desired position is passed
257 as a marker, avoid call to buf_charpos_to_bytepos.
258 * window.c (Fset_window_point): Omit redundant type checking.
259 (Fset_window_start): Likewise. Format comment.
260 (window_scroll_pixel_based): Use set_marker_restricted_both
261 with character and byte positions obtained from an iterator.
262 (Fset_window_configuration): Use set_marker_restricted_both.
263 * xdisp.c (message_dolog): Likewise.
265 2013-02-10 Eli Zaretskii <eliz@gnu.org>
267 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
268 When text lines are longer than window's screen lines, don't move back
269 too far. This speeds up some redisplay operations. (Bug#13675)
271 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
273 * syntax.c (scan_sexps_forward): Fix byte position calculation
274 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
276 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
278 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
281 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
283 Minor hashing refactoring.
284 * fns.c (SXHASH_REDUCE): Move to lisp.h.
285 (sxhash_float): Return EMACS_UINT, for consistency with the other
287 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
288 non-static inline function and therefore can't use static vars.
289 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
290 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
291 with the other hash functions.
293 2013-02-09 Eli Zaretskii <eliz@gnu.org>
295 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
296 XXXXXX part of the temporary file pattern is not downcased even
297 when w32-downcase-file-names is non-nil. (Bug#13661)
299 * xdisp.c (decode_mode_spec): Remove handling of %t.
301 * msdos.c (careadlinkatcwd): Remove.
303 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
305 * lread.c (skip_dyn_bytes): New function (bug#12598).
306 (read1): Use it. Use getc instead of READCHAR to read bytes.
307 (load_each_byte): Remove. Update users.
309 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
311 * search.c (scan_buffer): Calculate end byte position just once.
312 (scan_newline): Do not recalculate start_byte.
313 (search_command): Use eassert.
314 * syntax.c (struct lisp_parse_state): New member location_byte.
315 (scan_sexps_forward): Record from_byte and avoid redundant
316 character to byte position calculation ...
317 (Fparse_partial_sexp): ... here. Break too long line.
319 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
321 * lisp.h (make_uninit_vector): New function.
322 * alloc.c (Fvector, Fmake_byte_code):
323 * ccl.c (Fregister_ccl_program):
324 * charset.c (Fdefine_charset_internal, define_charset_internal):
325 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
326 * composite.c (syms_of_composite):
327 * font.c (Fquery_font, Ffont_info, syms_of_font):
328 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
329 * ftfont.c (ftfont_shape_by_flt):

331 * nsselect.m (clean_local_selection_data):
332 * syntax.c (init_syntax_once):
333 * w32unsubscribe.c (uniscribe_shape):
334 * window.c (Fcurrent_window_configuration):
335 * xfaces.c (Fx_family_fonts):
336 * xselect.c (selection_data_to_lisp_data): Use it.
338 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
340 * coding.c (Fdefine_coding_system_internal): Use AREF where
341 argument is known to be a vector.
342 * fns.c (Flocale_info): Likewise for ASET.
343 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
344 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
346 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
348 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
351 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
352 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
353 updateCollectionBehaviour.
355 * nsterm.m (NEW_STYLE_FS): Remove.
356 (ns_last_use_native_fullscreen): New variable.
357 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
358 (x_set_window_size): Do not take title bar and tool bar into account
359 if isFullscreen returns YES.
360 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
361 (check_native_fs): New function.
362 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
363 (ns_term_init): Remove NEW_STYLE_FS.
364 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
365 and tool bar if isFullscreen returns NO.
366 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
367 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
369 (window:willUseFullScreenPresentationOptions:): New method.
370 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
371 Hide toolbar if not enabled (Bug#13444).
372 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
373 Restore tool bar if enabled, hide it otherwise (Bug#13444).
374 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
375 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
376 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
377 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
378 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
379 (syms_of_nsterm): Add ns-use-native-fullscreen.
381 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
383 * fileio.c (Qchoose_write_coding_system): Now static.
385 2013-02-04 Eli Zaretskii <eliz@gnu.org>
387 * xdisp.c (window_buffer_changed): region_showing can be negative,
388 which still means region is being displayed.
389 (redisplay_internal): Resurrect code that forced redisplay of the
390 whole window when showing region and the mark has changed.
391 Record the new mark position to allow redisplay optimizations.
392 (display_line): If it->region_beg_charpos is non-zero, set the
393 window's region_showing member to -1. (Bug#13623) (Bug#13626)
395 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
396 not bitfield of 1 bit.
398 2013-02-03 Daniel Colascione <dancol@dancol.org>
400 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
401 daemon mode works on cygw32 when Emacs is installed and not just
404 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
406 Avoid file time stamp bug on MS-Windows (Bug#13149).
407 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
408 as FAT32 doesn't update time stamps when truncating them.
409 Also, check that a file time stamp is not a multiple of 100 ns;
410 this should catch all instances of the problem on MS-Windows,
411 as its native file system resolution is 100 ns or worse, and
412 checking for a non-multiple of 100 ns should impose only a small
413 overhead on systems with ns resolution.
415 2013-02-02 Eli Zaretskii <eliz@gnu.org>
417 Avoid encoding file names on MS-Windows when they need to be run
418 through dostounix_filename.
419 * w32.c (normalize_filename): Accept an additional argument
420 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
421 downcase it even if w32-downcase-file-names is non-nil.
422 (dostounix_filename): Accept an additional argument MULTIBYTE and
423 pass it to normalize_filename.
424 (emacs_root_dir): Adjust.
426 * msdos.h (dostounix_filename): Adjust prototype.
428 * w32.h (dostounix_filename): Adjust prototype.
430 * msdos.c (dostounix_filename): Accept an additional argument and
432 (init_environment): Adjust callers of dostounix_filename.
434 * fileio.c (Ffile_name_directory, file_name_as_directory)
435 (directory_file_name, Fexpand_file_name)
436 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
438 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
440 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
441 variables, as egetenv is case-insensitive for DOS_NT.
443 * dired.c (file_name_completion): Don't call Fdirectory_file_name
444 with an encoded file name.
446 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
447 Adjust calls to dostounix_filename.
449 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
451 * unexw32.c (unexec): Adjust call to dostounix_filename.
453 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
455 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
458 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
461 * callproc.c (Fcall_process): Make sure program name in PATH and
462 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
463 is passed to exec/spawnve, which fails unless the file-name
466 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
467 even if w32-quote-process-args is nil.
469 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
471 Fix timestamp bug when write-region appends nothing (Bug#13149).
472 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
473 the file's time stamp doesn't change if Emacs happens to write nothing
474 to the file, and on a buggy file system this could cause Emacs to
475 incorrectly infer that the file system doesn't have the bug.
476 Avoid this problem by inhibiting the inference in this case.
478 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
480 * window.h (struct window): Convert base_line_number, base_line_pos
481 and column_number_displayed members from Lisp_Object to ptrdiff_t.
482 Convert region_showing member from Lisp_Object to bitfield.
483 Remove sequence_number member. Adjust comments.
484 * window.c (sequence_number): Remove.
485 (make_window): Initialize column_number_displayed.
486 * print.c (print_object): Follow the printed representation of
487 frames and print window pointer to distinguish between windows.
488 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
489 * xdisp.c (wset_base_line_number, wset_base_line_pos)
490 (wset_column_number_displayed, wset_region_showing): Remove.

500 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
501 * dired.c: Include <fcntl.h>.
502 (open_directory): New function, which uses open and fdopendir
503 rather than opendir. DOS_NT platforms still use opendir, though.
504 (directory_files_internal, file_name_completion): Use it.
505 (file_attributes): New function, with most of the old Ffile_attributes.
506 (directory_files_internal, Ffile_attributes): Use it.
507 (file_attributes, file_name_completion_stat): First arg is now fd,
508 not dir name. All uses changed. Use fstatat rather than lstat +
510 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
511 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
512 (emacs_readlinkat): New function, with much of the old
513 Ffile_symlink_p, but with an fd argument for speed.
514 It uses readlinkat rather than careadlinkatcwd, so that it
515 need not assume the working directory.
516 (Ffile_symlink_p): Use it.
517 * filelock.c (current_lock_owner): Use emacs_readlinkat
518 rather than emacs_readlink.
519 * lisp.h (emacs_readlinkat): New decl.
520 (READLINK_BUFSIZE, emacs_readlink): Remove.
521 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.

531 (Fwrite_region): Update for new choose_write_coding_system args.
532 Move the last piece of choose_write_coding_system here. (Bug#13522)
533 (syms_of_fileio): Add choose-write-coding-system.
535 2013-01-30 Eli Zaretskii <eliz@gnu.org>
537 * w32.c (sys_open): Zero out the flags for the new file descriptor.
538 (sys_close): Zero out the flags for the file descriptor before
539 closing it. (Bug#13546)
541 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
542 (logon_network_drive, stat_worker, symlink, chase_symlinks):
543 Use CharNextExA and CharPrevExA to iterate over file names encoded in
546 * w32.c (w32_get_long_filename, init_environment, readlink):
547 Support file names encoded in DBCS codepages.
548 (readlink): Use the current file-name-coding-system, not the ANSI
549 codepage, to decode and handle targets of symlinks.
551 2013-01-28 Eli Zaretskii <eliz@gnu.org>
553 * w32.c (opendir): Now accepts a 'const char *'.
555 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
557 Remove obsolete redisplay code. See the discussion at
558 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
559 * dispnew.c (preemption_period, preemption_next_check): Remove.
560 (Vredisplay_preemption_period): Likewise.
561 (update_frame, update_single_window, update_window, update_frame_1):
562 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
563 used, following the 2012-06-22 change.
565 2013-01-25 Eli Zaretskii <eliz@gnu.org>
567 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
569 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
571 * font.c (num_fonts): Remove the leftover from old
572 debugging code. Adjust comment style here and there.

577 2013-01-25 Eli Zaretskii <eliz@gnu.org>
579 * w32.c (max_filename_mbslen): New function.
580 (normalize_filename, readdir): Use it to detect locales where ANSI
581 encoding of file names uses a double-byte character set (DBCS).
582 If a DBCS encoding is used, advance by characters using
583 CharNextExA, instead of incrementing a 'char *' pointer.
584 Use _mbslwr instead of _strlwr. (Bug#13515)
586 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
587 request of memory reservation to 1.7GB. (Bug#13065)
589 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
591 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
592 at check_extra_latin label. (Bug#13505)
594 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
596 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
597 Avoid redundant calls to strlen.
599 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
601 Drop async_visible and async_iconified fields of struct frame.
602 This is possible because async input is gone; for details, see
603 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
604 * frame.h (struct frame): Remove async_visible and async_iconified
605 members, convert garbaged to unsigned bitfield. Adjust comments.
606 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
607 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
608 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
609 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
610 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
612 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
613 properly. Likewise for obscured.
615 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
618 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
620 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
622 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
623 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
625 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
627 * xdisp.c (message2, message2_nolog): Remove functions.
628 (message3, message3_nolog): Extract nbytes and multibyteness directly
629 from the string. Change all callers.
630 (message3_nolog): Don't set message_enable_multibyte since set_message
631 will reset it anyway.
632 (message1, message1_nolog): Use message3.
633 (vmessage): Use a stack allocated buffer rather than f->message_buf.
634 (with_echo_area_buffer): Remove last two arguments. Update all callers.
635 (set_message): Drop all but the second arg, which has to be a string.
636 (set_message_1): Simplify now that we know that a1 is NULL and the
637 second arg is a string.
638 * frame.h (struct frame): Remove `message_buf' field.
639 Use glyphs_initialized_p instead.
640 (FRAME_MESSAGE_BUF): Remove macro.

642 * lisp.h (message2, message2_nolog): Remove declarations.
643 (message3, message3_nolog): Update declarations.
644 * keyboard.c (read_char_minibuf_menu_text)
645 (read_char_minibuf_menu_width): Remove vars.
646 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
647 to correctly handle multibyte strings.
648 * frame.c (delete_frame): Don't free message_buf any more.
649 * editfns.c (message_text, message_length): Remove vars.
650 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
651 * fileio.c (auto_save_error): Use message3 instead of message2.
652 * dispnew.c (adjust_frame_message_buffer): Remove function.
654 2013-01-23 Eli Zaretskii <eliz@gnu.org>
656 * w32term.c (w32fullscreen_hook): Account correctly for the screen
657 real estate used for the tool bar and the menu bar.
659 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
661 * insdel.c (prepare_to_modify_buffer): Force redisplay if
662 hidden buffer is prepared to modification (Bug#13164).
664 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
666 * window.h (struct window): Change window_end_valid member from
667 Lisp_Object to a bitfield. Adjust comments.
668 (wset_window_end_valid): Remove.
669 * window.c (adjust_window_count): Clear window_end_valid.
670 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
671 (Fwindow_line_height, set_window_buffer, Frecenter)
672 (Fsplit_window_internal, Fdelete_other_windows_internal)
673 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
674 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
675 * xdisp.c (check_window_end, reconsider_clip_changes)
676 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
677 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
678 (find_first_unchanged_at_end_row, try_window_id): Likewise.
680 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
682 * xdisp.c (mark_window_display_accurate): Simplify the loop
683 assuming that the only one of vchild, hchild or buffer window
684 slots is non-nil. Call mark_window_display_accurate_1 for
685 the leaf windows only.
686 (mark_window_display_accurate_1): Always assume leaf window.
689 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
691 * emacs.c (Qkill_emacs_hook): Now static.
693 * fileio.c (Finsert_file_contents): Simplify.
694 Remove unnecessary assignments and tests.
696 2013-01-21 Eli Zaretskii <eliz@gnu.org>
698 * w32.c (acl_set_file): Don't test for errors unless
699 set_file_security returns FALSE. Avoids spurious errors when
702 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
704 * fileio.c (Finsert_file_contents): Revert code introduced at
705 2013-01-18 in favor of the simpler and generally better fix.
706 Save stack space by removing 'buffer' and reusing 'read_buf'
709 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
711 * lisp.h (eabs): Define unconditionally (Bug#13419).
712 The old "#if !defined (eabs)" was an unnecessary revenant of back
713 when this macro was called "abs". Document 'eabs' better.
715 2013-01-19 Glenn Morris <rgm@gnu.org>
717 * fns.c (Frandom): Doc fix.
719 2013-01-19 Eli Zaretskii <eliz@gnu.org>
721 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
722 segfault when there are lots of overlays.
724 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
725 when there are lots of overlays.
726 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
727 for the details and a way to reproduce.
729 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
731 * fileio.c: Use O_APPEND to append.
732 This corresponds better to the natural interpretation of "append",
733 and avoids the need to open the output file twice, or to invoke
734 lseek when APPEND is neither nil nor a number.
735 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
736 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
737 file possibly twice, and lseeking to its end; this avoids the
738 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
739 at the same time: the combination is never needed and apparently
740 it doesn't work with DOS_NT.
742 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
743 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
745 Allow floating-point file offsets.
746 Problem reported by Vitalie Spinu in
747 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
748 * fileio.c (emacs_lseek): Remove.
749 (file_offset): New function.
750 (Finsert_file_contents, Fwrite_region): Use it.
752 2013-01-19 Chong Yidong <cyd@gnu.org>
754 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
755 aborting on Fsignal (Bug#13289).
757 2013-01-19 Eli Zaretskii <eliz@gnu.org>
759 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
760 set_file_security as failure due to insufficient privileges.
761 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
762 (fstat): Return owner and group like 'stat' and 'lstat' do.
764 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
766 Work around bug in CIFS and vboxsf file systems (Bug#13149).
767 The bug was observed on Ubuntu operating inside a virtual machine,
768 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
769 The workaround introduces a race condition on non-buggy hosts,
770 but it's an unlikely race and anyway there's a nearly identical
771 nearby race that can't be fixed.
772 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
774 (Fwrite_region): Test for file system time stamp bug.
775 (init_fileio): New function.
776 * lisp.h (init_fileio): Declare it.
777 * emacs.c (main): Call it.
779 * fileio.c (Finsert_file_contents): Simplify new diagnostic
780 and make it more consistent with other stat-failure diagnostics.
782 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
784 Fix crash when inserting data from non-regular files.
785 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
786 for the error description produced by valgrind.
787 * fileio.c (read_non_regular): Rename to read_contents.
788 Free Lisp_Save_Value object used to pass parameters.
789 (read_non_regular_quit): Rename to read_contents_quit.
790 (Finsert_file_contents): Redesign internal file reading loop to adjust
791 gap and end positions after each read and so help make_gap to work
792 properly. Do not signal an I/O error too early and so do not leave
793 not yet decoded characters in a buffer, which was the reason of
794 redisplay crash. Use list2 to build return value. Adjust comments.
796 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
798 Close a race when statting and reading files (Bug#13149).
799 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
800 This avoids a race if the file is renamed between stat and open.
801 This race is not the problem originally noted in Bug#13149;
802 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
804 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

812 * alloc.c (format_save_value): Rename to make_save_value.
813 (make_save_pointer): New function.
814 (record_xmalloc): Use make_save_pointer.
815 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
816 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
817 Change users of make_save_value to make_save_pointer.
818 Likewise for format_save_value and make_save_value.

836 (non_regular_nbytes): Remove.
837 (Finsert_file_contents): Convert trytry to ptrdiff_t.
838 Use format_save_value to pass parameters to read_non_regular.
839 (read_non_regular): Use XSAVE_ macros to extract parameters.
841 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
843 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
845 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
847 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
848 extraction from any Lisp_Save_Value slot. Add type checking.
849 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
850 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
851 * xselect.c: All users changed.

870 * dired.c (directory_files_internal_unwind):
871 * fileio.c (do_auto_save_unwind):
872 * gtkutil.c (pop_down_dialog):
873 * keymap.c (map_keymap_char_table_item):
874 * lread.c (load_unwind):
875 * nsmenu.m (pop_down_menu):
876 * print.c (print_object) [GC_MARK_STACK]:
877 * xfns.c (clean_up_file_dialog):
878 * xmenu.c (cleanup_widget_value_tree):
879 Omit casts between XSAVE_POINTER and a pointer type.
881 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
883 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
884 * eval.c (eval_sub): Protect `form' from being GCed before its
885 car and cdr becomes protected with the backtrace entry.

897 (free_misc): Likewise. Adjust comment.
898 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
899 (free_save_value): Likewise.
900 (mark_object): Likewise.
901 * editfns.c (save_excursion_save): Pack everything within
902 Lisp_Save_Value and so avoid xmalloc.
903 (save_excursion_restore): Adjust to match new layout. Use free_misc
904 because we do not allocate extra memory any more. Add eassert.
905 * print.c (print_object): New code to print Lisp_Save_Value. Do not
906 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
907 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
908 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
909 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.

972 string cross-reference(s).
974 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
976 Avoid unnecessary byte position calculation for the gap movement.
977 Since all users of move_gap do CHAR_TO_BYTE for other purposes
978 anyway, all of them should use move_gap_both instead.
979 * lisp.h (move_gap): Remove prototype.
980 * insdel.c (move_gap): Remove.
981 (move_gap_both): Add eassert.

988 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
990 * term.c (init_tty): Use them instead of rolling our own code.
991 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
992 switches from 'signal' to 'pthread_sigmask', which is safer in
993 multithreaded applications.
994 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
995 which has already arranged for that.
996 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
997 This is the main part of the bug fix.

1012 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1013 predicate. Adjust comment.

1016 left-margin-width, right-margin-width, left-fringe-width,
1017 right-fringe-width, scroll-bar-width and buffer-display-count.
1018 Use Qstringp for default-directory, buffer-file-name,
1019 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1020 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1022 * data.c (store_symval_forwarding): Adjust to call the predicate.

1038 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1039 (make_gap_1): New function to adjust the gap of any buffer.
1040 * coding.c (coding_alloc_by_making_gap): Use it.
1041 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1042 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1044 2013-01-08 Juri Linkov <juri@jurta.org>

1065 trailing dash is properly added.
1067 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1069 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1070 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1071 digits for buffer positions, before misalignment starts.
1072 Display "0" for integer "object" field.
1073 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1074 Display the newline glyph more unambiguously.
1076 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1078 * nsterm.m (ns_draw_underwave):
1079 * w32term.c (w32_draw_underwave):
1080 * xterm.c (x_draw_underwave): Make underwave look more triangular
1081 and also degrade gracefully for small fonts. (Bug#13000)
1083 * nsterm.m (ns_draw_text_decoration):
1084 * w32term.c (x_draw_glyph_string):
1085 * xterm.c (x_draw_glyph_string): Don't use previous underline
1086 thickness and position if previous underline type is underwave.
1088 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1090 * fileio.c (Ffile_acl): Undocument return format.
1092 2013-01-02 Glenn Morris <rgm@gnu.org>
1094 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

1104 * lread.c (read_list):
1105 * minibuf.c (Ftry_completion):
1106 * term.c (tty_ins_del_lines):
1107 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1108 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1110 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1112 * w32.c (unsetenv): Set up the string passed to _putenv
1114 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1115 for the bug this caused.
1117 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1119 * coding.c (Qmac): Now static.
1121 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1123 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1124 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1128 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1129 Show all on TOOLBAR_TOP_WIDGET.
1130 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1131 by TOOLBAR_TOP_WIDGET.
1132 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1133 Check toolbar_is_packed.
1134 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1136 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1138 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1139 (xg_update_menubar): Update title only if
1140 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1141 (xg_update_submenu): Skip tearoff only if
1142 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1143 (xg_initialize): Initialize xg_detached_menus only if
1144 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1146 * xterm.h (struct x_output): Surround handlebox_widget with
1147 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1148 toolbar_in_hbox is bool.
1150 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1152 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1153 (LIBS_GNUSTEP): Define.
1154 (LIBES): Add $(LIBS_GNUSTEP).
1155 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1157 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1159 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1160 continuation glyph on a TTY with an indication of an empty line.
1163 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1165 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1166 file's SELinux context or ACLs successfully set, nil otherwise.
1168 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

1171 SetEvent and WaitForSingleObject.
1173 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1175 Port EXTERNALLY_VISIBLE to Clang 3.2.
1176 * conf_post.h (__has_attribute): New macro.
1177 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1179 2012-12-27 Glenn Morris <rgm@gnu.org>
1181 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1182 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1184 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1186 * fileio.c (file_name_as_directory, directory_file_name):
1187 Accept an additional argument MULTIBYTE to indicate whether the input C
1188 came from a multibyte or a unibyte Lisp string; all callers
1189 adjusted. Don't assume the input string is always multibyte.
1191 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1192 don't ENCODE_FILE them, and return a unibyte string if the input
1194 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1195 don't assume the input strings will always be multibyte. If the
1196 input strings are multibyte, decode strings obtained from C
1199 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1201 * lisp.h (toplevel): Add two notices to the comment about
1202 defining a new Lisp data type.

1206 * alloc.c (valid_lisp_object_p): Adjust comment.
1208 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1210 * keyboard.c (record_asynch_buffer_change): Initialize an event
1211 only if it's really needed.
1212 * frame.h (enum output_method): Remove output_mac member since
1213 it's a leftover from the deleted code.
1214 * frame.c (Fframep): Adjust user here ...
1215 * terminal.c (Fterminal_live_p): ... and here.
1216 * coding.c (Qmac): Now here because it's only used to denote
1217 end-of-line encoding type.
1218 (syms_of_coding): DEFSYM it.
1219 * frame.h (Qmac): Remove duplicated declaration.
1221 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1223 * window.c (select_window_1): Now static, since it's used only here.
1225 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1227 * window.c (window_body_cols): Subtract display margins from the
1228 window body width on TTYs as well. See
1229 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1230 for the original report.
1232 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1234 * xdisp.c (redisplay_window): Remove inner local variable
1235 because the outer shadowed one has the same meaning.
1236 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1238 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1239 (xg_create_tool_bar): Adjust users.
1241 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1243 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1244 * buffer.c (Fget_buffer_create): Use it to set compact field of
1245 struct buffer_text to avoid accessing an uninitialized value
1246 when compact_buffer is called for the first time.
1247 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1248 (Fset_buffer_modified_p): Use buffer_window_count to check
1249 whether the buffer is displayed in some window.
1250 * xdisp.c (message_dolog): Likewise.
1252 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1254 * w32.c (acl_set_file): If setting the file security descriptor
1255 fails, and the new DACL is identical to the existing one, silently
1256 return success. This fixes problems for users backing up their
1257 own files without having the necessary privileges for setting
1258 security descriptors.
1260 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1262 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1263 after WaitForSingleObject returns normally. This expedites reader
1264 thread shutdown when delete_child triggers it.
1265 (reap_subprocess): More accurate commentary for why we call
1266 delete_child only when cp->fd is negative.
1268 * w32.c (sys_close): Do not call delete_child on a subprocess
1269 whose handle is not yet closed. Instead, set its file descriptor
1270 to a negative value, so that reap_subprocess will call
1271 delete_child on that subprocess when its SIGCHLD arrives.
1272 This avoids closing handles used for communications between sys_select
1273 and reader_thread, which doesn't give sys_select a chance to
1274 notice that the process exited and invoke the SIGCHLD handler for
1277 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1279 * nsfns.m (Fns_do_applescript): Run event loop until script has
1280 been executed (Bug#12969).

1288 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1290 * w32term.c (w32fullscreen_hook): New function.
1291 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1293 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1295 * fileio.c (Finsert_file_contents): Doc fix.
1297 * w32proc.c (new_child, delete_child, find_child_pid): For a
1298 subprocess, consider its slot being in use as long as its process
1299 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1300 slot when a new process is started immediately after killing
1301 another one, without waiting enough time for the first process to
1302 be reaped and resources allocated for it be orderly freed.
1304 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1306 2012-12-21 Chong Yidong <cyd@gnu.org>
1308 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1310 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1312 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1314 * w32.c (get_name_and_id): Always pass NULL as the first argument
1315 of lookup_account_sid. Avoids crashes with UNC file names that
1316 refer to DFS domains, not to specific machine names. (Bug#12621)
1317 Remove now unused argument FNAME; all callers changed.
1318 (get_file_owner_and_group): Remove now unused argument FNAME; all
1321 2012-12-21 Chong Yidong <cyd@gnu.org>
1323 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1324 error for invalid chars, don't check for a nil return value.
1326 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1328 Avoid calls to CHAR_TO_BYTE if byte position is known.
1329 * editfns.c (make_buffer_string_both): Use move_gap_both.
1330 (Fbuffer_string): Use make_buffer_string_both.

1333 (buf_bytepos_to_charpos): Likewise.
1334 (charpos_to_bytepos): Remove.
1335 * fileio.c (Finsert_file_contents): Use move_gap_both.
1336 * search.c (Freplace_match): Likewise.
1337 * process.c (process_send_region): Likewise. Use convenient
1338 names for byte positions.
1339 * lisp.h (charpos_to_bytepos): Remove prototype.
1340 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1341 * insdel.c (move_gap): Likewise.

1349 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1350 (redisplay_internal): Don't bother selecting the frame to get the
1351 proper value of frame-local variables (bug#13225).
1353 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1355 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1356 Rename 4th argument since it may be buffer or string. Adjust comment.
1357 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1359 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1361 * coding.c (Fdetect_coding_region): Do not check start and end with
1362 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1363 (code_convert_region): Likewise.
1365 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1367 * w32.c (acl_get_file, acl_set_file): Run the file name through
1368 map_w32_filename, and resolve any symlinks in the file name, like
1370 (acl_set_file): Call revert_to_self, if any privileges were
1373 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1375 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1376 ($(BLD)/w32.$(O)): Update dependencies.
1378 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1380 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1381 propagate redisplay's scrolling (if any) to the right window.
1382 (redisplay_internal): Use ensure_selected_frame.
1383 (display_mode_lines): Complete last fix.
1384 * window.c (select_window_1): New func, extracted from select_window.
1385 (select_window): Use it.
1386 * window.h (select_window_1): Declare.
1388 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1390 Emulate Posix ACL APIs on MS-Windows.
1391 * w32.c: Include sddl.h and sys/acl.h.

1410 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1412 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1414 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1415 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1416 for some of that bug's symptoms can now cause Emacs to abort.
1417 Remove the workaround.
1418 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1419 The bug that caused SIGCHLD to get lost has been fixed, and the
1420 workaround for it can now cause Emacs to abort.
1422 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1424 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1425 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in

1430 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1431 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1432 and copy ACL entries of file in addition to SELinux context if set.
1433 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1435 * Makefile.in (LIBACL_LIBS): New macro.

1450 * w32proc.c (new_child): Initialize input_file and
1451 pending_deletion members of the child.
1452 (delete_child): Delete the child's temporary input file, if any,
1453 that is pending deletion.
1454 (register_child): First argument is now pid_t.
1455 (record_infile, record_pending_deletion): New functions.
1456 (reap_subprocess): Fix a typo in DebPrint string.
1457 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1459 * fileio.c (internal_delete_file): Return an int again: non-zero
1460 if delete-file succeeds, zero otherwise.
1462 * lisp.h (internal_delete_file): Adjust prototype.
1464 * callproc.c (Fcall_process): Don't overwrite infile with result
1466 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1467 asynchronous subprocess, record the name of the input file name,
1469 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1470 delete the file, record it as pending deletion when the subprocess
1473 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1475 * editfns.c [HAVE_PWD_H]: Include grp.h.

1481 Fix permissions bugs with setgid directories etc. (Bug#13125)
1482 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1483 to mark it as a placeholder. The old value was often wrong.
1484 The only user of this attribute has been changed to use
1485 file-ownership-preserved-p instead, with its new group arg.
1486 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1493 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1495 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1496 try to get accurate owner and group information from NT file
1497 security APIs. This is to make most callers of 'stat' and
1498 'lstat', which don't need that information, much faster.
1500 * dired.c (Ffile_attributes) [WINDOWSNT]:
1501 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1502 owner and group information from 'lstat'.
1504 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1506 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1507 as that confuses set-auto-coding, so insist on the head-read
1508 returning the full 1024 bytes. Let lseek compute the tail offset;
1509 less work for us. Do not ignore I/O errors when reading the tail.

1512 (init_iterator): Hoist assignment out of if-expression.
1513 (markpos_of_region): Callers now test for sign, not for -1.

1532 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1533 files, fixing a regression from 24.2.
1534 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1536 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1538 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1539 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1540 Remove unnecessary S_ISLNK test, as (contra the comments) this
1541 function can't copy symlinks. Improve quality of error message
1542 when attempting to copy files that are neither regular files nor

1555 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1556 the dumped Emacs is not a sparse file, greatly improving Cygwin
1557 "make bootstrap" performance.
1559 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1561 * inotify.c (inotify_callback): Generate an Emacs event for every
1562 incoming inotify event.
1564 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1566 * xdisp.c (handle_face_prop): Fix logic of computing
1567 it->start_of_box_run_p.
1568 (append_space_for_newline): If the glyph row is R2L, reset the
1569 iterator's end_of_box_run_p flag before prepending the space glyph.
1570 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1571 iterator's start_of_box_run_p flag before prepending the stretch.

1573 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1574 left_box_line_p and right_box_line_p flags of the glyph for R2L
1575 glyph rows. (Bug#13011)

1589 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1590 encoded_file_name, which is what it is.
1592 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1622 variable here so various initialization calls DTRT.
1624 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1625 (hinst): Remove unneeded extern declaration.
1626 (_start): Remove initialization of above variables; remove

1846 * frame.c (make_frame): Do not set window's buffer to t.
1847 * window.c (Fsplit_window_internal): Likewise. Previously it was

1850 (Fset_window_buffer): ... is always true and can be removed.
1852 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1854 Convenient macro to check whether the buffer is hidden.

1883 New function, containing part of the old call_process_kill.
1884 (call_process_kill): Use it.
1885 This does not change call_process_kill's behavior.
1886 * process.c (Fdelete_process): Use record_kill_process to fix a
1887 race condition that could cause Emacs to lose track of a child.
1889 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>

1895 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1897 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1898 fails, signal an error instead of continuing with an empty
1900 Encode expanded temp file pattern before passing it to mkstemp or
1903 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1904 Encode the file name before passing it to dostounix_filename, in
1905 case it will downcase it (under w32-downcase-file-names).
1908 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1910 Minor call-process cleanups.
1911 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1912 at the same time as other platforms, to simplify analysis.
1913 No need for fd0_volatile since we have synch_process_fd.
1914 Avoid needless emacs_close; arg is always negative.
1916 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1918 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1921 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1923 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1924 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1925 and mouse_face_hidden members to a bitfields.
1926 * frame.h (struct frame): Remove set-but-not-used space_width member.
1927 (FRAME_SPACE_WIDTH): Remove.
1928 * nsterm.m, w32term.c, xterm.c: Adjust users.
1929 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1930 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1931 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1932 members to a bitfields.
1934 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1936 Don't let call-process be a zombie factory (Bug#12980).
1937 Fixing this bug required some cleanup of the signal-handling code.
1938 As a side effect, this change also fixes a longstanding rare race
1939 condition whereby Emacs could mistakenly kill unrelated processes,
1940 and it fixes a bug where a second C-g does not kill a recalcitrant
1941 synchronous process in GNU/Linux and similar platforms.
1942 The patch should also fix the last vestiges of Bug#9488,
1943 a bug which has mostly been fixed on the trunk by other changes.
1944 * callproc.c, process.h (synch_process_alive, synch_process_death)
1945 (synch_process_termsig, sync_process_retcode):
1946 Remove. All uses removed, to simplify analysis and so that
1947 less consing is done inside critical sections.
1948 * callproc.c (call_process_exited): Remove. All uses replaced
1949 with !synch_process_pid.
1950 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1951 These take the role of what used to be in unwind-protect arg.
1953 (block_child_signal, unblock_child_signal):
1954 New functions, to avoid races that could kill innocent-victim processes.
1955 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1956 (call_process_kill): Record killed processes as deleted, so that
1957 zombies do not clutter up the system. Do this inside a critical
1958 section, to avoid a race that would allow the clutter.
1959 (call_process_cleanup): Fix code so that the second C-g works again
1960 on common platforms such as GNU/Linux.
1961 (Fcall_process): Create the child process in a critical section,
1962 to fix a race condition. If creating an asynchronous process,
1963 record it as deleted so that zombies do not clutter up the system.
1964 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1965 light of these changes. Omit unnecessary call to emacs_close
1966 before failure, as the unwind-protect code does that.
1967 * callproc.c (call_process_cleanup):
1968 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1969 * process.c (record_deleted_pid): New function, containing
1970 code refactored out of Fdelete_process.
1971 (Fdelete_process): Use it.
1972 (process_status_retrieved): Remove. All callers changed to use
1973 child_status_change.
1974 (record_child_status_change): Remove, folding its contents into ...
1975 (handle_child_signal): ... this signal handler. Now, this
1976 function is purely a handler for SIGCHLD, and is not called after
1977 a synchronous waitpid returns; the synchronous code is moved to
1978 wait_for_termination. There is no need to worry about reaping
1979 more than one child now.
1980 * sysdep.c (get_child_status, child_status_changed): New functions.
1981 (wait_for_termination): Now takes int * status and bool
1982 interruptible arguments, too. Do not record child status change;
1983 that's now the caller's responsibility. All callers changed.
1984 Reimplement in terms of get_child_status.
1985 (wait_for_termination_1, interruptible_wait_for_termination):
1986 Remove. All callers changed to use wait_for_termination.
1987 * syswait.h: Include <stdbool.h>, for bool.
1988 (record_child_status_change, interruptible_wait_for_termination):
1990 (record_deleted_pid, child_status_changed): New decls.
1991 (wait_for_termination): Adjust to API changes noted above.
1993 * bytecode.c, lisp.h (Qbytecode): Remove.
1994 No longer needed after 2012-11-20 interactive-p changes.
1996 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1998 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1999 the scroll margin, move point outside the margin. (Bug#13055)

2003 * gtkutil.c (my_log_handler): New function.
2004 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2006 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2008 * lisp.h (modify_region): Rename to...
2009 (modify_region_1): ...new prototype.
2010 * textprop.c (modify_region): Now static. Adjust users.
2011 * insdel.c (modify_region): Rename to...
2012 (modify_region_1): ...new function to work with current buffer.
2013 Adjust comment and users. Use true and false for booleans.
2015 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2017 * alloc.c (free_save_value): New function.
2018 (safe_alloca_unwind): Use it.
2019 * lisp.h (free_save_value): New prototype.
2020 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2022 (save_excursion_restore): Adjust to match saved data structure.
2023 Use free_save_value to offload some work from GC. Drop obsolete
2026 2012-12-03 Chong Yidong <cyd@gnu.org>
2028 * fileio.c (Vauto_save_list_file_name): Doc fix.
2030 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2032 * w32fns.c: Remove prototype of atof.
2033 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2035 (file_dialog_callback): Make it UINT_PTR.
2037 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2040 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2041 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2044 2012-12-03 Glenn Morris <rgm@gnu.org>
2046 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2048 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2050 Fix xpalloc confusion after memory is exhausted.
2051 * alloc.c (xpalloc): Comment fix.
2052 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2053 and signals an error, do not clear charset_table_size, as
2054 charset_table is still valid.
2055 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2057 Use execve to avoid need to munge environ (Bug#13054).
2058 * callproc.c (Fcall_process):
2059 * process.c (create_process):
2060 Don't save and restore environ; no longer needed.
2061 * callproc.c (child_setup):
2062 Use execve, not execvp, to preserve environ.
2064 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2066 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2068 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2070 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2071 display for sliced images (Bug#10500).
2073 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2075 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2077 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2078 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2080 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2082 * xdisp.c (window_outdated): Remove eassert since it hits
2083 some suspicious corner cases (see Bug#13007 and Bug#13012).
2084 (mode_line_update_needed): New function.
2085 (redisplay_internal, redisplay_window): Use it.
2086 (ensure_selected_frame): New function.
2087 (redisplay_internal, unwind_redisplay): Use it.
2088 (redisplay_internal): Move comment about buffer_shared...
2089 (buffer_shared_and_changed): ...near to its real use.
2091 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2093 * callproc.c (Fcall_process): Don't misreport vfork failure.
2095 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2097 * callproc.c (Fcall_process): Fix vfork portability problems.
2098 Do not assume that fd[0], count, filefd, and save_environ survive
2099 vfork. Fix bug whereby wrong errno value could be reported for
2100 pipe failure. Some minor cleanups, too, as follows. Move buf and
2101 bufsize to the context where they're needed. Change new_argv to
2102 be of type char **, as this is more convenient and avoids casts.
2103 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2104 Now local constants, not macros.
2106 2012-11-18 Kenichi Handa <handa@gnu.org>
2108 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2109 for the variable "f".
2111 2012-11-13 Kenichi Handa <handa@gnu.org>
2113 * font.c (font_unparse_xlfd): Exclude special characters from the
2114 generating XLFD name.
2116 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2156 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2157 between bpos_covered and bpos_max. This fixes cursor display when
2158 several display strings follow each other.
2160 * .gdbinit (pgx): If the glyph's object is a string, display the
2161 pointer to string data, rather than the value of the string object
2162 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2164 * indent.c (Fvertical_motion): If the starting position is covered
2165 by a display string, return to one position before that, to avoid
2166 overshooting it inside move_it_to. (Bug#12930)

2187 of a literal "/". (Bug#12955)
2188 (gl-stamp): Invoke fc.exe directly, not through cmd.

2193 * dired.c: Assume HAVE_DIRENT_H.
2194 (NAMLEN): Remove, replacing with ...
2195 (dirent_namelen): New function. All uses changed. Use the GNU macro
2196 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2197 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2198 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2199 * makefile.w32-in (DIR_H): Remove. All uses replaced with

2204 Do not include <dirent.h>; no longer needed.
2205 * w32.c: Include <dirent.h> rather than "ndir.h".
2207 2012-11-23 Chong Yidong <cyd@gnu.org>
2209 * xftfont.c (xftfont_open): Remove duplicate assignment.
2211 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>

2214 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2215 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2216 * msdos.c (IT_frame_up_to_date): Use it here...
2217 * w32term.c (w32_frame_up_to_date): ...here...

2259 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2261 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2263 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2264 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2265 Define for the MSVC compiler.
2267 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

2272 dostounix_filename assumes it gets a unibyte string.
2273 Reported by Michel de Ruiter <michel@sentient.nl>, see

2322 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2324 * w32select.c: Include w32common.h before w32term.h, so that
2325 windows.h gets included before w32term.h uses some of its
2326 features, see below.
2328 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2330 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2354 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2356 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2357 * callproc.c (relocate_fd): Assume F_DUPFD.
2358 * emacs.c, term.c (O_RDWR): Remove.
2359 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2360 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2361 * nsterm.m: Assume <fcntl.h> exists.
2362 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2363 (create_pty, Fmake_network_process, server_accept_connection)
2364 (wait_reading_process_output, init_process_emacs):
2366 (wait_reading_process_output): Put in a special case for WINDOWSNT
2367 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2368 It's not clear this is needed, but it's a more-conservative change.
2369 (create_process): Assume FD_CLOEXEC.
2370 (create_process, create_pty): Assume O_NOCTTY.
2371 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2372 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2373 Omit if not DOS_NT, since F_GETFL is not defined there.
2374 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2375 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2377 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2378 lack it, since gnulib guarantees this.
2379 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2381 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2383 * w32.c (faccessat): Pretend that directories have the execute bit
2384 set. Emacs expects that, e.g., in files.el:cd-absolute.
2386 * w32proc.c (create_child): Don't clip the PID of the child
2387 process to fit into an Emacs integer, as this is no longer a
2389 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2390 reaping only the process specified by PID argument, if that is
2391 positive. Use PID instead of dead_child to know which process to
2392 reap. Wait for the child to die only if WNOHANG is not in
2394 (sys_select): Don't set dead_child.
2396 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2397 as it is no longer needed.
2399 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2401 (record_child_status_change): Remove the setting of
2402 record_at_most_one_child for the !WNOHANG case.
2404 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2406 Fix problems in ns port found by static checking.
2407 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2408 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2409 not to process group.
2410 (ns_select): Use emacs_write, not write, as that's more robust
2411 in the presence of signals.
2412 (fd_handler:): Check for read errors.
2414 2012-11-16 Glenn Morris <rgm@gnu.org>
2416 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2418 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2420 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2422 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2424 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2425 use the same value of thread handle.
2426 (start_timer_thread): If the timer thread exited (due to error),
2427 clean up by closing the two handles it used. Duplicate the caller
2428 thread's handle here, so it gets duplicated only once, when
2429 launching the timer thread. Set priority of the timer thread, not
2431 (getitimer): Don't duplicate the caller thread's handle here.
2434 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2436 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2439 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2441 Remove no-longer-used pty_max_bytes variable.
2442 * process.c (pty_max_bytes): Remove; unused.
2443 (send_process): Do not set it.
2445 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2447 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2448 Update dependencies.
2450 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2452 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2453 This follows up on the 2012-09-29 patch that removed indirection
2454 for the 'function' field. Reported by Sergey Vinokurov in
2455 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2457 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2459 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2460 different name, as the MS runtime does not have such a function,
2461 and probably never will.) All callers changed. Ignore DIRFD
2462 value if PATH is an absolute file name, to match Posix spec
2463 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2466 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2468 * xdisp.c (echo_area_display, redisplay_internal):
2469 Omit redundant check whether frame_garbaged is set.
2471 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2473 Use faccessat, not access, when checking file permissions (Bug#12632).
2474 This fixes a bug that has been present in Emacs since its creation.
2475 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2476 which must set some sort of record. (Torek's bug report was against
2477 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2478 same common flaw.) See Torek's Usenet posting
2479 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2480 Posted: Fri Apr 8 14:18:56 1983.
2481 * Makefile.in (LIB_EACCESS): New macro.
2483 * callproc.c (init_callproc):
2484 * charset.c (init_charset):
2485 * fileio.c (check_existing, check_executable, check_writable)
2487 * lread.c (openp, load_path_check):
2488 * process.c (allocate_pty):
2490 Use effective UID when checking permissions, not real UID.
2491 * callproc.c (init_callproc):
2492 * charset.c (init_charset):
2493 * lread.c (load_path_check, init_lread):
2494 Test whether directories are accessible, not merely whether they exist.
2495 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2496 * fileio.c (check_existing, check_executable, check_writable)
2498 Use symbolic names instead of integers for the flags, as they're
2500 (check_writable): New arg AMODE. All uses changed.
2501 Set errno on failure.
2502 (Ffile_readable_p): Use faccessat, not stat + open + close.
2503 (Ffile_writable_p): No need to call check_existing + check_writable.
2504 Just call check_writable and then look at errno. This saves a syscall.
2505 dir should never be nil; replace an unnecessary runtime check
2506 with an eassert. When checking the parent directory of a nonexistent
2507 file, check that the directory is searchable as well as writable, as
2508 we can't create files in unsearchable directories.
2509 (file_directory_p): New function, which uses 'stat' on most platforms
2510 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2511 (Ffile_directory_p, Fset_file_times): Use it.
2512 (file_accessible_directory_p): New function, which uses a single
2513 syscall for efficiency.
2514 (Ffile_accessible_directory_p): Use it.
2515 * xrdb.c (file_p): Use file_directory_p.
2516 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2517 * lread.c (openp): When opening a file, use fstat rather than
2518 stat, as that avoids a permissions race. When not opening a file,
2519 use file_directory_p rather than stat.
2520 (dir_warning): First arg is now a usage string, not a format.
2521 Use errno. All uses changed.
2522 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2523 that merely introduced a race.
2524 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2525 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2526 and similarly for the other O_* flags.
2527 * w32.c (sys_faccessat): Rename from sys_access and switch to
2528 faccessat's API. All uses changed.
2529 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2530 (magic_db): Rename from magic_file_p.
2531 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2532 char *, so that we don't have to test for file existence
2533 separately from opening the file for reading. This removes a race
2534 fixes a permission-checking problem, and simplifies the code.
2536 (file_p): Remove; no longer needed.
2538 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2540 Omit glyphs initialization at startup.
2541 * dispnew.c (glyphs_initialized_initially_p): Remove.
2542 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2543 (Fredraw_frame): Move actual code from here...
2544 (redraw_frame): ...to here. Add eassert. Adjust comment.
2545 (Fredraw_display): Use redraw_frame.
2546 * xdisp.c (clear_garbaged_frames): Likewise.
2548 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2550 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2551 passed to pint2str and pint2hrstr to be at most the size of the
2552 frame's decode_mode_spec_buffer. This avoids crashes with very
2553 large values of FIELD_WIDTH argument to decode_mode_spec.
2556 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2558 Fix a race with verify-visited-file-modtime (Bug#12863).
2559 Since at least 1991 Emacs has ignored an mtime difference of no
2560 more than one second, but my guess is that this was to work around
2561 file system bugs that were fixed long ago. Since the race is
2562 causing problems now, let's remove that code.
2563 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2564 whose time stamp is off by no more than a second. Insist that the
2565 file time stamps match exactly.
2567 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2569 * frame.h (struct frame): Convert external_tool_bar member to
2570 1-bit unsigned bitfield.
2571 * termhooks.h (struct terminal): Remove mouse_moved member since
2572 all users are long dead. Adjust comment on mouse_position_hook.
2574 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2576 Simplify by using FOR_EACH_FRAME here and there.
2577 * frame.c (next_frame, prev_frame, other_visible_frames)
2578 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2579 * w32term.c (x_window_to_scroll_bar): Likewise.
2580 * window.c (window_list): Likewise.
2581 * xdisp.c (x_consider_frame_title): Likewise.
2582 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2583 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2584 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2585 * xmenu.c (menubar_id_to_frame): Likewise.
2586 * xselect.c (frame_for_x_selection): Likewise.
2587 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2588 (x_window_to_menu_bar): Likewise.
2589 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2591 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2593 * data.c (Qdefalias_fset_function): Now static.
2595 Another tweak to vectorlike_header change.
2596 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2597 Remove, and replace all uses with ...
2598 (next_in_free_list, set_next_in_free_list):
2599 New functions, which respect C's aliasing rules better.
2601 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2603 * window.c (list4i): Rename from 'quad'. All uses changed.
2604 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2606 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2608 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2609 warning about mixing declarations and code in ISO C90.
2611 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2613 * window.c (Fsplit_window_internal): Set combination limit of
2614 new parent window to t iff Vwindow_combination_limit is t;
2615 fixing a regression introduced with the change from 2012-09-22.
2616 (Fset_window_combination_limit): Fix doc-string.
2618 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2620 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2621 amount when the scroll margins are too large. When scrolling
2622 backwards in the buffer, give up if cannot reach point or the
2623 scroll margin within a reasonable number of screen lines.
2624 Fixes point position in window under scroll-up/down-aggressively when
2625 point is positioned many lines beyond the window top/bottom.
2628 * ralloc.c (relinquish): If real_morecore fails to return memory
2629 to the system, don't crash; instead, leave the last heap
2630 unchanged and return. (Bug#12774)
2632 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2634 * lisp.h (AUTOLOADP): New macro.
2635 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2636 * data.c (Ffset): Remove special ad-advice-info handling.
2637 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2639 (Finteractive_form): Simplify.
2640 (Fquo): Don't insist on having at least 2 arguments.
2641 (Qdefalias_fset_function): New var.
2643 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2645 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2651 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2653 Fix recently introduced crash on MS-Windows (Bug#12839).
2654 * w32term.h (struct scroll_bar): Use convenient header.
2655 (SCROLL_BAR_VEC_SIZE): Remove.
2656 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2658 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2660 Tweak last vectorlike_header change.
2661 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2662 vectorlike object on the free list. This is introduced to avoid
2663 some (but not all) pointer casting and aliasing problems, see
2664 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2665 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2667 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2669 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2671 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2672 been removed, so remove them here also.
2674 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2676 * doc.c (Fdocumentation): Handle new property
2677 dynamic-docstring-function to replace the old ad-advice-info.
2679 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2681 * fns.c (Qeql, hashtest_eq): Now static.

2690 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2692 Use same hash function for hashfn_profiler as for hash_string etc.
2693 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2694 * lisp.h (sxhash_combine): New inline function, with the contents
2695 of the old SXHASH_COMBINE.
2696 * profiler.c (hashfn_profiler): Use it, instead of having a
2697 special hash function containing a comparison that always yields 1.
2699 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2701 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2702 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2703 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2706 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2708 * image.c (xpm_make_color_table_h): Fix compiler error because
2709 make_hash_table changed.
2711 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2713 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2715 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2717 Use ad-hoc comparison function for the profiler's hash-tables.
2718 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2719 (make_log): Use them.

2730 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2731 (hash_lookup, hash_remove_from_table): Move assertion checking of
2732 hashfn result here. Check hash-equality before calling cmpfn.

2742 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2744 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2745 value of w32-scroll-lock-modifier is neither nil nor one of the
2746 known key modifiers. (Bug#12806)
2748 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2750 Shrink struct vectorlike_header to the only size field.
2751 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2753 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

2771 (struct large_vector): New type to represent allocation unit for
2772 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2773 (large_vectors): Change type to struct large_vector.
2774 (allocate_vector_from_block): Simplify.
2775 (PSEUDOVECTOR_NBYTES): Replace with...

2785 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2787 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2788 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2789 (copy_hash_table): Adjust to match vector header change.
2790 * lread.c (defsubr): Use XSETPVECTYPE.
2791 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2792 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2793 (xvecsize): New command.
2795 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2797 * keyboard.c (event_to_kboard): Do not dereference
2798 frame_or_window field of SELECTION_REQUEST_EVENT
2799 and SELECTION_CLEAR_EVENT events (Bug#12814).
2800 * xterm.h (struct selection_input_event): Adjust comment.
2802 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2804 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2805 such as Scroll Lock, if the respective keys are treated as
2806 function keys, not as modifiers. This avoids destroying non-ASCII
2807 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2809 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2811 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2813 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2815 Restore some duplicate definitions (Bug#12814).
2816 This undoes part of the 2012-11-03 changes. Some people build
2817 with plain -g rather than with -g3, and they need the duplicate
2818 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2819 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2820 Define as macros, as well as as enums or as constants.
2822 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2824 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2825 to keypad keys (Bug#12816).
2827 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2829 Minor adjustments of recently-changed frame functions.
2830 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2831 known to be a frame (we're in the FRAMEP branch).
2832 * lisp.h (Qframep): Remove decl. frame.h declares this.
2833 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2834 since they're meant for Lisp fixnum values.
2836 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2838 * window.c (Fwindow_combination_limit): Revert to the only
2839 required argument and adjust docstring as suggested in
2840 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2841 by Martin Rudalics <rudalics@gmx.at>.
2843 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2845 Widely used frame validity and checking functions.
2846 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2847 * frame.c (decode_live_frame, decode_any_frame): New functions.
2848 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2849 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2850 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2851 (Fframe_pointer_visible_p): Use decode_any_frame.
2852 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2853 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2854 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2855 (Fframe_focus): Likewise. Allow zero number of arguments.
2857 (frame_buffer_list, frame_buffer_predicate): Remove.
2858 * lisp.h (frame_buffer_predicate): Remove prototype.
2859 * buffer.c (Fother_buffer): Use decode_any_frame.
2860 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2861 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2862 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2863 (Fclose_font, Ffont_info): Use decode_live_frame.
2864 * fontset.c (check_fontset_name): Likewise.
2865 * terminal.c (Fframe_terminal): Likewise.
2866 * w32fns.c (check_x_frame): Likewise.
2867 * window.c (Fminibuffer_window, Fwindow_at)
2868 (Fcurrent_window_configuration): Likewise.
2869 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2870 Likewise. Allow zero number of arguments. Adjust docstring.
2871 * dispnew.c (Fredraw_frame): Likewise.
2872 * xfaces.c (frame_or_selected_frame): Remove.
2873 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2874 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2875 (Fframe_face_alist): Use decode_live_frame.
2876 * xfns.c (check_x_frame): Likewise.
2878 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2880 * window.c (quad): New function.
2881 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2882 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2883 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2884 (Fwindow_line_height): Use it.
2885 (Fwindow_fringes): Use list3.
2886 (Fwindow_scroll_bars): Use list4.
2887 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2888 (Fwindow_combination_limit): Allow zero number of arguments.
2890 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2892 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2894 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2895 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2896 file descriptor 2 for standard error. (Bug#12805)
2898 2012-11-05 Chong Yidong <cyd@gnu.org>
2900 * process.c (wait_reading_process_output): Revert previous change.
2902 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2904 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2905 This removes code that has been obsolete since around 1990.
2906 * callproc.c (Fcall_process):
2908 * process.c (create_process):
2909 * term.c (dissociate_if_controlling_tty):
2910 Assume setsid exists.
2911 * callproc.c (child_setup): Assume setpgid exists and behaves as
2912 per POSIX.1-1988 or later.
2913 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2914 * emacs.c (shut_down_emacs):
2915 * sysdep.c (sys_suspend, init_foreground_group):
2916 Assume getpgrp behaves as per POSIX.1-1998 or later.
2917 * msdos.c (setpgrp): Remove.
2918 (tcgetpgrp, setpgid, setsid): New functions.
2919 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2920 * term.c (no_controlling_tty): Remove; unused.
2921 * w32proc.c (setpgrp): Remove.
2922 (setsid, tcgetpgrp): New functions.
2924 Simplify by assuming __fpending.
2925 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2926 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2927 Do not assume that __fpending's result fits in int.
2929 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2931 Remove EMACS_OUTQSIZE+sleep hack.
2932 * dispnew.c (update_frame_1): Remove hack for terminals slower
2933 than 2400 bps, which throttled Emacs by having it sleep.
2934 This code hasn't worked since at least 2007, when the multi-tty stuff
2935 was added, and anyway those old terminals are long dead.
2936 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2937 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2939 Fix data-loss with --version (Bug#9574).
2940 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2941 as we can't assume that emacs_strerror is initialized, and strerror
2942 is good enough here.
2943 (main): Invoke atexit earlier, to catch earlier instances of
2944 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2946 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2948 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2949 (keyDown): Remap keypad keys to X11 virtual key codes.
2951 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2953 Fix data-loss with --batch (Bug#9574).
2954 * emacs.c: Include <close-stream.h>.
2955 (close_output_streams): New function.
2956 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2957 and handles errors appropriately.
2958 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2961 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2962 The symptom is a diagnostic "GLib-WARNING **: In call to
2963 g_spawn_sync(), exit status of a child process was requested but
2964 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2965 waitpid(), so exit status can't be returned." The diagnostic
2966 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2967 The real bug is a race condition between Emacs and glib: Emacs
2968 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2969 so that glib can't find it. Work around the bug by invoking
2970 waitpid only on subprocesses that Emacs itself creates.
2971 * process.c (create_process, record_child_status_change):
2972 Don't use special value -1 in pid field, as the caller now must
2973 know the pid rather than having the callee infer it.
2974 The inference was sometimes incorrect anyway, due to another race.
2975 (create_process): Set new 'alive' member if child is created.
2976 (process_status_retrieved): New function.
2977 (record_child_status_change): Use it.
2978 Accept negative 1st argument, which means to wait for the
2979 processes that Emacs already knows about. Move special-case code
2980 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2981 processes that have already been waited for, by testing and
2982 clearing new 'alive' member.
2983 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2984 now does this internally.
2985 (handle_child_signal): Let record_child_status_change do all
2986 the work, since we do not want to reap all exited child processes,
2987 only the child processes that Emacs itself created.
2988 * process.h (Lisp_Process): New boolean member 'alive'.
2990 Omit duplicate definitions no longer needed with gcc -g3.
2991 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2992 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2993 Define only as macros. There's no longer any need to also define
2994 these symbols as enums or as constants, since we now assume
2995 gcc -g3 when debugging.
2997 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2999 * lisp.mk: Adjust comments to the fact that term/internal is now
3000 loaded from loadup.el.
3002 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3003 (msdos_fatal_signal): New function.
3004 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3007 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3008 for GCC versions before 4.
3009 (emacs_raise): Define to call msdos_fatal_signal.
3011 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3012 iterator when starting in the middle of a display or overlay
3015 2012-11-03 Chong Yidong <cyd@gnu.org>
3017 * process.c (wait_reading_process_output): Clean up the last
3020 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3022 * process.c (wait_reading_process_output): Avoid a race condition
3023 with SIGIO delivery (Bug#11536).
3025 2012-11-03 Chong Yidong <cyd@gnu.org>
3027 * buffer.c (cursor_type): Untabify docstring.
3029 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3031 * frame.h (struct frame): Drop can_have_scroll_bars member
3032 which is meaningless for a long time. Adjust comments.
3033 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3034 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3036 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3038 * window.c (decode_next_window_args): Update window arg after
3039 calling decode_live_window and so fix crash reported at
3040 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3041 by Juanma Barranquero <lekktu@gmail.com>.
3042 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3043 * font.c (Ffont_at): Likewise.
3045 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3047 * widget.c (resize_cb): New function.
3048 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3049 (EmacsFrameResize): Check if all is up to date before changing frame
3052 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3054 Implement backtrace output for fatal errors on MS-Windows.
3055 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3056 (BACKTRACE_LIMIT_MAX): New macro.
3057 (w32_backtrace): New function.
3058 (emacs_abort): Use w32_backtrace when the user chooses not to
3059 attach a debugger. Update the text of the abort dialog.
3061 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3063 Window-related stuff cleanup here and there.
3064 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3065 Use decode_any_window.
3066 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3067 * xdisp.c (Fformat_mode_line): Likewise.
3068 * font.c (Ffont_at): Use decode_live_window.
3069 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3070 * window.c (decode_next_window_args): Likewise.
3071 (decode_any_window): Remove static.
3072 * window.h (decode_any_window): Add prototype.
3073 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3074 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3077 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3079 Remove pad from struct input_event.
3080 * termhooks.h (struct input_event): Remove padding field.
3082 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3083 member is never cons for a long time. Adjust comment.
3084 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3085 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3086 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3087 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3089 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3091 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3093 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3095 Fix crash when using Emacs as commit editor for git (Bug#12697).
3096 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3097 and it is configured in conf_post.h.
3098 (Fcall_process): Don't invoke both setsid and setpgid; the former
3099 is enough, if it exists.
3100 * callproc.c (Fcall_process, child_setup):
3101 * process.c (create_process): Use setpgid.
3102 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3104 * dispnew.c (init_display): Initialize the foreground group
3105 if we are running a tty display.
3106 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3107 * lisp.h (init_foreground_group): New decl.
3108 * sysdep.c (inherited_pgroup): New static var.
3109 (init_foreground_group, tcsetpgrp_without_stopping)
3110 (narrow_foreground_group, widen_foreground_group): New functions.
3111 (init_sys_modes): Narrow foreground group.
3112 (reset_sys_modes): Widen foreground group.
3114 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3116 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3118 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3120 * minibuf.c (read_minibuf): Restore current buffer since
3121 choose_minibuf_frame calling Fset_frame_selected_window may
3122 change it (Bug#12766).
3124 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3126 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3128 2012-10-30 Kenichi Handa <handa@gnu.org>
3130 * font.c (Ffont_at): If WINDOW is specified and it is not
3131 displaying the current buffer, signal an error.
3133 2012-10-29 Daniel Colascione <dancol@dancol.org>
3135 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3136 In preparation for fixing bug#12739, move these functions from
3139 * coding.h, coding.c: ... to here, and compile them only when
3140 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3141 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3143 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3145 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3146 (timer_loop, getitimer, setitimer): Use it instead of
3147 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3149 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3152 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3154 * nsterm.m (NO_APPDEFINED_DATA): New define.
3155 (last_appdefined_event_data): New variable
3156 (last_appdefined_event): Remove.
3157 (ns_select): Initialize t from last_appdefined_event_data instead
3158 of [last_appdefined_event data1].
3159 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3160 remove last_appdefined_event (Bug#12698).
3162 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3164 * frame.c (x_set_font): Catch internal error.
3166 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3168 Avoid overflow in w32 implementation of interval timers.
3169 When possible, for ITIMER_PROF count only times the main thread
3171 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3172 'volatile ULONGLONG' types. All the other data which was
3173 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3174 (GetThreadTimes_Proc): New typedef.
3175 (w32_get_timer_time): New function, returns a suitable time value
3177 (timer_loop): Enter critical section when accessing ULONGLONG
3178 values of the itimer_data struct, as these accesses are no longer
3179 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3180 Remove unused variable.
3181 (init_timers): Initialize s_pfn_Get_Thread_Times.
3182 (start_timer_thread): Don't assign itimer->caller_thread here.
3183 (getitimer): Assign itimer->caller_thread here.
3184 (setitimer): Always call getitimer to get the value of ticks_now.
3185 (sys_spawnve): Avoid compiler warning about format mismatch.
3187 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3189 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3190 mouse movement events if the menu bar is active. This avoids
3191 producing a busy "hour-glass" cursor by Windows if the mouse
3192 pointer is positioned over a tooltip shown for some menu item.
3194 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3196 Don't assume process IDs fit in int.
3197 * emacs.c (shut_down_emacs) [!DOS_NT]:
3198 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3199 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3200 Use pid_t, not int, to store process IDs, as 'int'
3201 is not wide enough on a few platforms (e.g., AIX and IRIX).
3203 2012-10-23 Kenichi Handa <handa@gnu.org>
3205 The following change is to make face-font-rescale-alist work
3206 correctly for non-ASCII fonts.
3208 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3209 (font_open_for_lface): Handle Vface_font_rescale_alist.
3211 2012-10-23 Chong Yidong <cyd@gnu.org>
3213 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3215 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3217 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3219 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3221 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3224 2012-10-21 Glenn Morris <rgm@gnu.org>
3226 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3228 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3230 Port to OpenBSD 5.1.
3231 * frame.c (Fmouse_position, Fmouse_pixel_position):
3232 * xdisp.c (produce_stretch_glyph):
3233 Declare local vars only when they're needed.
3234 This is clearer and avoids a warning on OpenBSD about unused vars.
3235 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3236 This is safer, and avoids OpenBSD warnings about unused vars.
3237 * keyboard.c (record_menu_key): Remove unnecessary decl.
3238 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3239 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3240 as our definition clashes with OpenBSD's.

3716 now a supported configuration.
3718 * Makefile.in: consolidate image variables into LIBIMAGE; add
3719 W32_OBJ and W32_LIBS. Compile new files.
3722 (_DebPrint) declare tracing facility for W32 debugging. We need
3723 to unify tracing later.
3725 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3726 unconditional use of W32 Unicode functions. Cygwin runs only on
3727 100% Unicode operating systems.
3729 * cygw32.c: New file. Define Cygwin-specific facilities.
3730 (Fcygwin_convert_path_to_windows)
3731 (Fcygwin_convert_path_from_windows): New user functions for
3732 accessing Cygwin path-munging routines.
3734 * cygw32.h: New file.
3735 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3736 UTF-16LE strings temporarily inside non-Lisp-visible string
3739 (w32_strerror): Just what it says on the tin.
3741 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3742 also run for Cygwin; both systems have the same problem with using
3743 GUI facilities in a forked child. Also call syms_of_cygw32,
3744 syms_of_w32select in correct places.
3746 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3747 needs fork-then-exec for daemon launching.
3749 * font.h: Include frame.h.
3751 * image.c: Use the image library cache machinery only when we're
3752 compiling for native WINDOWSNT; Cygwin can use shared libraries
3753 like any other Unixlike system.
3755 * keyboard.c: Clarify a comment regarding the input loop.
3757 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3758 functions directly instead of trying to detect at runtime that our
3759 host operating system supports them. We make this change for two
3760 reasons: Cygwin lacks support for the multibyte character
3761 conversion functions used by the legacy menu code, and Cygwin
3762 never needs to rely on non-Unicode APIs.
3764 * unexw32.c (hinst): Declare extern.
3766 * w32.c: Change header order;
3767 (w32_strerror): Move to w32fns.c because we need it for
3768 non-WINDOWSNT builds.
3770 * w32.h: Add #error macro to make sure we don't include w32.h for
3771 Cygwin builds. Remove w32select declarations.
3773 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3774 w32fns.c. w32console.c is WINDOWSNT-only.
3776 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3777 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3779 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3780 (w32_major_version, w32_minor_version, w32_build_number)
3781 (os_subtype, sound_type): Define here
3782 (w32_defined_color): Make color parameter const for consistency
3783 with other _defined_color functions.
3784 (w32_createwindow): Unconditionally call w32_init_class instead of
3785 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3786 through the code is complex and unnecessary because class
3787 registration is practically free.
3788 (w32_name_of_message): New EMACSDEBUG-only function.
3789 (Fset_message_beep): Move here
3790 (Fx_open_connection): Require that the display name for Windows be
3791 "w32" for consistency, emacsclient disambiguation, and maybe, one
3792 day, multi-window-system support.
3793 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3794 Cygwin files for W32 GUI facilities, since these clearly don't
3795 expect Cygwin names.
3796 (_DebPrint): Define.
3797 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3798 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3799 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3800 (w32_last_error): Remove.
3802 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3804 * w32heap.c (syspage_mask): Declare here.
3805 (cache_system_info): Remove.
3807 * w32inevt.c (faked_key): Define globally, not statically.
3808 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3809 (w32_console_toggle_lock_key): Move to w32fns.c.
3811 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3813 * w32proc.c (_DebPrint): Move to w32fns.c.
3814 * w32select.c: Include string.h, stdio.h for Cygwin.
3815 * w32select.h: New File.
3817 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3819 (w32_message_fd): New variable. Under Cygwin, holds the file
3820 descriptor the system used to tell us about pending thread
3823 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3824 that prevented compilation under non-WINDOWSNT systems.
3826 (w32_initialize): Open /dev/windows and assign it to
3827 w32_message_fd. Provide w32 feature.
3829 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3830 (WM_EMACS_INPUT_READY): add.
3831 (prepend_msg, w32_message_fd): Declare globally.
3834 (keyboard_handle): Use only when WINDOWSNT.
3835 (notify_msg_ready): New function. Posts a message to the main
3836 thread's message queue under CYGWIN, which wakes up the main
3837 thread from select(2) by making the /dev/windows file descriptor
3838 ready. Under WINDOWSNT, it sets an event the same way the old
3841 (post, prepend_msg): Actually call notify_msg_ready instead of
3842 setting the input event directly.
3844 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3846 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3847 but it still has blocs in it, don't return it to the system,
3848 instead of aborting. (Bug#12402)
3850 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3852 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3854 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3855 MAC_OS_X_VERSION_10_6.
3856 (syms_of_nsterm): Remove comment about Panther and above for
3858 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3859 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3860 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3862 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3863 MAC_OS_X_VERSION_10_4.
3865 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3866 MAC_OS_X_VERSION_10_2.
3868 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3870 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3871 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3873 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3874 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3875 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3876 Remove ns_in_resize check.
3877 (ns_clear_frame_area): Remove resize handle code.
3879 * nsfns.m (ns_in_resize): Remove.
3880 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3881 Remove ns_in_resize check.
3883 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3885 Improve sys_siglist detection.
3886 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3887 defined as a macro, as is done in Solaris.
3888 (sys_siglist_entries): New macro.
3889 (save_strsignal): Use it.
3890 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3891 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3893 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3895 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3896 fullscreen/Fullscreen.
3898 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3899 tobar_height is new.
3901 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3902 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3903 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3904 (windowDidResize:): Check for correct window if old style fullscreen.
3905 Capitalize word in comment. Remove incorrect comment.
3906 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3907 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3908 error in drawing background.
3909 (toggleFullScreen:): Remove comment. Rearrange calls.
3910 Set toolbar values to zero, save old height in tobar_height.
3911 Restore tool bar height when leaving fullscreen.
3912 (canBecomeMainWindow): New function.
3914 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3916 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3918 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3920 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3922 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3923 that time stamps of directories could also be changed.
3924 Don't request the too broad GENERIC_WRITE, only the more restrictive
3925 FILE_WRITE_ATTRIBUTES access rights.
3927 * fileio.c (Fset_file_times): Special-case ignoring errors for
3928 directories only on MSDOS, not on MS-Windows.
3930 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3932 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3934 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3936 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3937 see whether CreateFile failed.
3939 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3941 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3942 to avoid similar races.
3943 * keyboard.c (pending_signals): Now bool, not int.
3945 Port timers to OpenBSD, plus check for timer failures.
3946 OpenBSD problem reported by Han Boetes.
3947 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3949 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3950 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3951 like OpenBSD, which has timer_settime but does not declare it.
3952 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3953 whether to use itimerspec-related primitives. All uses of
3954 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3956 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3958 * profiler.c (handle_profiler_signal): Fix a malloc race
3959 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3961 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3963 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3965 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3967 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3968 consistent with the change in return value of 'safe_strsignal'.
3970 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3972 Prefer plain 'static' to 'static inline' (Bug#12541).
3973 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3974 (bidi_set_sor_type, bidi_push_embedding_level)
3975 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3976 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3977 (bidi_cache_search, bidi_cache_ensure_space)
3978 (bidi_cache_iterator_state, bidi_cache_find)
3979 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3980 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3981 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3982 Now 'static', not 'static inline'.
3984 Count overruns when profiling; change units to ns.
3985 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3986 Give extra weight to samples after overruns, to attempt to count
3987 the time more accurately.
3988 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3989 the underlying primitives nominally do ns.
3990 (Fprofiler_cpu_start): Document the change. Mention that
3991 the sampling intervals are only approximate.
3993 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3995 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3997 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3998 case for the special 0 coding-system.
4000 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4001 (Fmake_overlay): Remove redundant tests.
4002 (fix_start_end_in_overlays): Remove redundant recentering.
4004 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4006 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4007 Update dependencies.
4009 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4011 Fix a malloc race condition involving strsignal.
4012 A signal can arrive in the middle of a malloc, and Emacs's signal
4013 handler can invoke strsignal, which can invoke malloc, which is
4014 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4015 Fix it by altering the signal handler so that it does not invoke
4017 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4018 * process.c (status_message): Use const pointer, in case strsignal
4019 is #defined to safe_strsignal.
4020 * sysdep.c (sys_siglist, init_signals): Always define and
4021 initialize a substitute sys_siglist if the system does not define
4022 one, even if HAVE_STRSIGNAL.
4023 (safe_strsignal): Rename from strsignal. Always define,
4024 using sys_siglist. Return a const pointer.
4025 * syssignal.h (safe_strsignal): New decl.
4026 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4028 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4030 * w32proc.c (timer_loop): Fix code that waits for timer
4031 expiration, to avoid high CPU usage.
4033 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4035 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4036 (sweep_weak_table): Remove redundant prototypes.
4038 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4040 * emacs.c: Move the inclusion of TERM_HEADER after including
4041 windows.h on WINDOWSNT. This avoids compilation problems with
4044 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4046 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4047 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4048 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4049 as the previous version used 'void *'.
4051 * ralloc.c (ROUNDUP): Fix last change.
4052 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4055 * w32proc.c <disable_itimers>: New static flag.
4056 (init_timers): Initialize it to zero, after creating the critical
4057 sections used by the timer threads.
4058 (term_timers): Set to 1 before deleting the critical sections.
4059 (getitimer, setitimer): If disable_itimers is non-zero, return an
4060 error indication without doing anything. Reported by Fabrice
4061 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4062 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4064 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4067 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4068 term_ntproc after all the other bookkeeping, to get timers working
4069 as long as possible.
4071 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4073 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4074 Suggested by Juri Linkov in
4075 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4077 Prefer plain 'static' to 'static inline' (Bug#12541).
4078 With static functions, modern compilers inline pretty well by
4079 themselves; advice from programmers often hurts as much as it helps.
4080 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4081 this change shrinks the text size of the Emacs executable by 1.1%
4082 without affecting CPU significantly in my benchmark.

4168 * dired.c (directory_files_internal, Ffile_attributes):
4171 * frame.c (x_report_frame_params): Port better to wider ints.
4172 Do not assume that EMACS_UINT is the same width as uprintmax_t,

4376 (handle_profiler_signal): Rename from sigprof_handler_1,
4377 for consistency with other handlers. Do not check whether
4378 cpu_log is a hash-table if garbage collecting, since it

4381 for consistency with other handlers.
4382 (setup_cpu_timer): New function, with much of what used to be in
4383 Fprofiler_cpu_start. Check for out-of-range argument.
4384 Prefer timer_settime if available, and prefer
4385 thread cputime clocks, then process cputime clocks, then
4386 monotonic clocks, to the old realtime clock. Use make_timeval
4387 to round more-correctly when falling back to setitimer.
4388 (Fprofiler_cpu_start): Use it.
4389 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4396 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4397 in profiler.c, since sysdep.c now uses it.
4399 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4455 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4456 Since this stuff is now private to charset.c, there's no need for
4457 a public macro and no need to inline by hand.

4531 (sys_kill): Improve commentary.
4533 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4534 consistency with a signature of a signal handler. All callers
4536 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4537 install term_ntproc as a signal handler for SIGABRT, as that
4538 should be done by the dumped Emacs.

4640 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4642 * makefile.w32-in (BLOCKINPUT_H): Remove.

4659 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4661 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4662 fatal_error_backtrace.
4664 * w32proc.c (sys_kill): Undo last change: don't do anything when
4665 invoked to deliver SIGABRT to our own process. This is now
4666 handled by emacs_raise.
4668 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4670 * w32term.c (w32_read_socket): Remove leftover reference to
4671 interrupt_input_pending.
4673 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4675 Do not use SA_NODEFER.
4676 Problem reported by Dani Moncayo in
4677 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4679 * sysdep.c (emacs_abort): Do not reset signal handler.
4680 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4681 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4682 wanted even on POSIXish hosts, and it doesn't work on Windows.
4684 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4686 * xterm.c (x_term_init): Call fixup_locale before and after calling
4687 gtk_init (Bug#12392).
4689 2012-09-23 Chong Yidong <cyd@gnu.org>
4691 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4692 Vdynamic_library_alist.
4694 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4695 (Fgnutls_available_p): Caller changed.
4697 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4698 (Flibxml_parse_xml_region): Likewise.
4700 * dispextern.h (struct image_type): Remove arg from init function.
4702 * image.c (Finit_image_library, lookup_image_type)
4703 (define_image_type): Remove now-unneeded second arg.
4704 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4705 (init_tiff_functions, init_gif_functions, init_svg_functions):
4706 Arglist and w32_delayed_load calling convention changed.
4707 (gs_type): Remove init_gs_functions; there is no such function.
4708 (valid_image_p, make_image): Fix caller to lookup_image_type.
4710 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4712 Simplify and avoid signal-handling races (Bug#12471).
4714 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4715 Avoid recursive loop if there's a fatal error in the function itself.
4716 * atimer.c (pending_atimers):
4717 * blockinput.h: Don't include "atimer.h"; no longer needed.
4718 (interrupt_input_pending): Remove. All uses removed.
4719 pending_signals now counts both atimers and ordinary interrupts.
4720 This is less racy than having three separate pending-signal flags.
4721 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4723 Rename from their upper-case counterparts BLOCK_INPUT,
4724 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4725 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4726 This makes it easier to access volatile variables more accurately.
4727 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4728 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4729 that's more reliable if the code is buggy and sets
4730 interrupt_input_blocked to a negative value. All uses changed.
4731 * atimer.c (deliver_alarm_signal):
4732 Remove. No need to deliver this to the parent; any thread can
4733 handle this signal now. All uses replaced by underlying handler.
4734 * atimer.c (turn_on_atimers):
4735 * dispnew.c (handle_window_change_signal):
4736 * emacs.c (handle_danger_signal):
4737 * keyboard.c (kbd_buffer_get_event):
4738 Don't reestablish signal handler; not needed with sigaction.
4739 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4741 Rework to avoid unnecessary accesses to volatile variables.
4742 (UNBLOCK_INPUT_TO): Now a function.
4743 (totally_unblock_input, unblock_input): New decls.
4744 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4745 (init_data): Remove. Necessary stuff now done in init_signal.
4746 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4747 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4748 (fatal_error_code): Remove; no longer needed.
4749 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4750 it doesn't always backtrace. All uses changed. No need to reset
4751 signal to default, since sigaction and/or die does that for us now.
4752 Use emacs_raise (FOO), not kill (getpid (), FOO).
4753 (main): Check more-accurately whether we're dumping.
4754 Move fatal-error setup to sysdep.c
4755 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4756 * gtkutil.c (xg_get_file_name, xg_get_font):
4757 Remove no-longer-needed signal-mask manipulation.
4758 * keyboard.c, process.c (POLL_FOR_INPUT):
4759 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4760 * keyboard.c (read_avail_input): Remove.
4761 All uses replaced by gobble_input.
4762 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4763 (kbd_buffer_store_event_hold, gobble_input):
4764 (record_asynch_buffer_change) [USABLE_SIGIO]:
4765 (store_user_signal_events):
4766 No need to mess with signal mask.
4767 (gobble_input): If blocking input and there are terminals, simply
4768 set pending_signals to 1 and return. All hooks changed to not
4769 worry about whether input is blocked.
4770 (process_pending_signals): Clear pending_signals before processing
4771 them, in case a signal comes in while we're processing.
4772 By convention callers now test pending_signals before calling us.
4773 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4774 New functions, to support changes to blockinput.h.
4775 (handle_input_available_signal): Now extern.
4776 (reinvoke_input_signal): Remove. All uses replaced by
4778 (quit_count): Now volatile, since a signal handler uses it.
4779 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4780 All callers changed. Block SIGINT only if not already blocked.
4781 Clear sigmask reliably, even if Fsignal returns, which it can.
4782 Omit unnecessary accesses to volatile var.
4783 (quit_throw_to_read_char): No need to restore sigmask.
4784 * keyboard.c (gobble_input, handle_user_signal):
4785 * process.c (wait_reading_process_output):
4786 Call signal-handling code rather than killing ourselves.
4787 * lisp.h: Include <float.h>, for...
4788 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4789 (pending_signals): Now volatile.
4790 (syms_of_data): Now const if IEEE floating point.
4791 (handle_input_available_signal) [USABLE_SIGIO]:
4792 (terminate_due_to_signal, record_child_status_change): New decls.
4793 * process.c (create_process): Avoid disaster if memory is exhausted
4794 while we're processing a vfork, by tightening the critical section
4796 (send_process_frame, process_sent_to, handle_pipe_signal)
4797 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4799 (send_process): No need for setjmp/longjmp any more, since the
4800 SIGPIPE stuff is now gone. Instead, report an error if errno
4802 (record_child_status_change): Now extern. PID and W are now args.
4803 Return void, not bool. All callers changed.
4804 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4805 Remove. All uses removed. This bug should be fixed now in a
4807 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4808 and record the child status change directly. This avoids the
4809 need to futz with the signal mask.
4810 (process_fatal_action): Move here from emacs.c.
4811 (emacs_sigaction_flags): New function, containing
4812 much of what used to be in emacs_sigaction_init.
4813 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4814 caught by emacs, to make races less likely.
4815 (deliver_process_signal): Rename from handle_on_main_thread.
4817 (BACKTRACE_LIMIT_MAX): Now at top level.
4818 (thread_backtrace_buffer, threadback_backtrace_pointers):
4820 (deliver_thread_signal, deliver_fatal_thread_signal):
4821 New functions, for more-accurate delivery of thread-specific signals.
4822 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4823 (deliver_arith_signal): Handle in this thread, not
4824 in the main thread, since it's triggered by this thread.
4825 (maybe_fatal_sig): New function.
4826 (init_signals): New arg DUMPING so that we can be more accurate
4827 about whether we're dumping. Caller changed.
4828 Treat thread-specific signals differently from process-general signals.
4829 Block all signals while handling fatal error; that's safer.
4830 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4832 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4833 Ignore SIGPIPE unless batch.
4834 (emacs_backtrace): Output backtrace for the appropriate thread,
4835 which is not necessarily the main thread.
4836 * syssignal.h: Include <stdbool.h>.
4837 (emacs_raise): New macro.
4838 * xterm.c (x_connection_signal): Remove; no longer needed
4839 now that we use sigaction.
4840 (x_connection_closed): No need to mess with sigmask now.
4841 (x_initialize): No need to reset SIGPIPE handler here, since
4842 init_signals does this for us now.
4844 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4846 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4847 background rect may be larger (Bug#12245).
4849 2012-09-23 Chong Yidong <cyd@gnu.org>
4851 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4853 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4855 * .gdbinit: Just stop at fatal_error_backtrace.
4856 See Stefan Monnier's request in
4857 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4858 Remove no-longer-used query of system type.
4860 2012-09-22 Chong Yidong <cyd@gnu.org>
4862 * search.c (Freplace_match): Doc fix (Bug#12325).
4864 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4866 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4867 (Fline_end_position): Doc fix.
4869 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4871 2012-09-22 Chong Yidong <cyd@gnu.org>
4873 * dispextern.h (struct image_type): Add new slot, storing a type
4874 initialization function.
4876 * image.c (define_image_type): Call the image initializer function
4877 if it is defined. Arguments and return value changed.
4878 (valid_image_p, make_image): Callers changed.
4879 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4880 (gif_type, imagemagick_type, svg_type, gs_type):
4881 Add initialization functions.
4882 (Finit_image_library): Call lookup_image_type.
4883 (CHECK_LIB_AVAILABLE): Macro deleted.
4884 (lookup_image_type): Call define_image_type here, rather than via
4885 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4886 (syms_of_image): Move define_image_type calls for xbm_type and
4887 pbm_type to lookup_image_type.
4889 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4891 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4892 'idle_timers' from here ...
4893 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4894 lists, to avoid infloops when the timer does something stupid,
4895 like reinvoke itself with the same or smaller time-out.
4898 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4900 * window.c (Fsplit_window_internal): Handle only Qt value of
4901 Vwindow_combination_limit separately.
4902 (Qtemp_buffer_resize): New symbol.
4903 (Vwindow_combination_limit): New default value.
4906 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4908 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4909 the new overlay string. (Bug#10159)
4911 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4913 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4914 or that fprintf is async-signal-safe. POSIX doesn't require
4917 2012-09-22 Chong Yidong <cyd@gnu.org>
4919 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4922 2012-09-22 Kenichi Handa <handa@gnu.org>
4924 * composite.c (composition_reseat_it): Handle the case that a
4925 grapheme cluster is not covered by a single font (Bug#12352).
4927 2012-09-21 Chong Yidong <cyd@gnu.org>
4929 * image.c (define_image_type): Avoid adding duplicate types to
4930 image_types (Bug#12463). Suggested by Jörg Walter.
4932 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4934 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4935 (print_load_command_name): Add case LC_DATA_IN_CODE.
4936 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4938 2012-09-21 Glenn Morris <rgm@gnu.org>
4940 * eval.c (Frun_hook_with_args_until_success)
4941 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4943 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4945 * fileio.c (Ffile_selinux_context): Only call freecon when
4946 lgetfilecon succeeded.
4947 (Fset_file_selinux_context): Likewise. (Bug#12444)
4949 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4951 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4952 reordering, locate the cursor by calling set_cursor_from_row; if
4953 that fails, clear the desired glyph matrix before returning a
4954 failure indication to the caller. Fixes leaving garbled display
4955 when fast scrolling with a down-key. (Bug#12403)
4956 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4957 scrolling through multibyte text.
4959 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4961 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4962 calling mark_vectorlike since that's the one that marks the window.
4963 (mark_discard_killed_buffers): Mark the final cdr.
4964 * window.h (struct window): Move prev/next_buffers to the
4965 non-standard fields.
4966 * window.c (make_window): Initialize prev/next_buffers manually.
4968 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4970 Omit unused arg EXPECTED from socket hooks.
4971 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4972 * nsterm.m (ns_term_init):
4973 * termhooks.h (struct terminal.read_socket_hook):
4974 * w32inevt.c (w32_console_read_socket):
4975 * w32term.c (w32_read_socket):
4976 * xterm.c (XTread_socket):
4977 Omit unused arg EXPECTED. All callers changed.
4978 (store_user_signal_events): Return void, not int, since callers no
4979 longer care about the return value. All uses changed.
4981 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4983 * w32gui.h (XParseGeometry): Do not declare.
4985 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4987 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4988 Ignore 'expected'. See Eli Zaretskii in
4989 <http://bugs.gnu.org/12471#8> (last line).
4991 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4992 (XParseGeometry): Now static. Substitute extremal values for
4993 values that are out of range.
4995 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4997 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4999 * nsfns.m (XParseGeometry): Remove.
5000 (Fx_create_frame): Call x_set_offset to correctly interpret
5001 top_pos in geometry.
5003 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5004 (Fx_parse_geometry): If there is a space in string, call
5005 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5007 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5009 * search.c (scan_buffer): Use character positions in calls to
5010 region_cache_forward and region_cache_backward, not byte
5011 positions. (Bug#12196)
5013 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5014 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5016 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5017 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5018 emacs_blocked_malloc, now deleted.
5020 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5022 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5023 The workaround was for improving performance on Solaris 2.4, but
5024 is getting in the way now. Emacs will still work if someone is
5025 still running Solaris 2.4 in a museum somewhere; Sun dropped
5026 support for Solaris 2.4 in 2003.
5027 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5028 * process.c (create_process) [HAVE_WORKING_VFORK]:
5029 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5030 since Emacs no longer uses vfork on that platform.
5032 2012-09-17 Glenn Morris <rgm@gnu.org>
5034 * emacs.c: Use COPYRIGHT.
5036 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5038 Remove configure's --without-sync-input option (Bug#12450).
5039 When auditing signal-handling in preparation for cleaning it up,
5040 I found that SYNC_INPUT has race conditions and would be a real
5041 pain to fix. Since it's an undocumented and deprecated
5042 configure-time option, now seems like a good time to remove it.
5043 Also see <http://bugs.gnu.org/11080#16>.
5044 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5045 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5046 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5047 (malloc_hysteresis):
5048 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5049 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5050 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5051 (dont_register_blocks, bytes_used_when_reconsidered)
5052 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5053 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5054 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5055 Remove. All uses removed.
5056 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5057 implementation, one that depends on whether the new macro
5058 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5060 * atimer.c (run_timers, handle_alarm_signal):
5061 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5062 (handle_async_input, process_pending_signals)
5063 (handle_input_available_signal, init_keyboard):
5064 * nsterm.m (ns_read_socket):
5065 * process.c (wait_reading_process_output):
5066 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5067 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5069 * xterm.c (XTread_socket):
5071 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5072 * eval.c (handling_signal): Remove. All uses removed.
5073 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5074 All uses replaced with the SYNC_INPUT version.
5075 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5077 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5080 * font.c (Ffont_shape_gstring): Remove unused local.
5082 2012-09-16 Glenn Morris <rgm@gnu.org>
5084 * Makefile.in (clean): No longer run nextstep's clean.
5086 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5088 (ns-app): Move here from ns.mk, and simplify.
5089 (clean): Simplify nextstep entry.
5090 * ns.mk: Remove file.
5092 2012-09-17 Kenichi Handa <handa@gnu.org>
5094 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5095 not covert the last few charactes.
5097 2012-09-16 Kenichi Handa <handa@gnu.org>
5099 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5100 here, but just check the validity of glyphs in the glyph-string.
5102 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5104 * window.c (Fwindow_parameter, Fset_window_parameter):
5105 Accept any window as argument (Bug#12452).
5107 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5109 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5110 to ns_term_init to avoid memory leak.
5112 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5113 explicit retain/release.
5114 (ns_term_init): Only allow one display. Initialize outerpool and
5117 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5119 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5120 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5121 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5122 the Microsoft problem in a different way, by altering ../nt/config.nt.
5124 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5139 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5140 by lisp.h. This completes removal of setjmp.h inclusion
5141 erroneously announced in the previous commit. (Bug#12446)
5143 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5146 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5147 not defined as a macro. The latter happens on MS-Windows.
5150 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5152 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5153 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5154 Some instances of '#include <setjmp.h>' removed, if the
5155 only reason for the instance was because "lisp.h" was included.
5156 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5157 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5158 and _longjmp with the new symbols. Emacs already uses _setjmp if
5159 available, so this change affects only POSIXish hosts that have
5160 sigsetjmp but not _setjmp, such as some versions of Solaris and
5161 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5162 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5163 (png_load_body) [HAVE_PNG]:
5164 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5165 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5166 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5167 since PNG requires jmp_buf. This is the only exception to the
5168 general rule that we now use sys_setjmp and sys_longjmp.
5169 This exception is OK since this code does not change the signal
5170 mask or longjmp out of a signal handler.
5172 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5174 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5175 Include "syssignal.h", for 'main_thread'.
5177 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5179 Avoid out-of-range marker position (Bug#12426).
5180 * insdel.c (replace_range, replace_range_2):
5181 Adjust markers before overlays, as suggested by comments.
5182 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5183 Remove redundant check before calling offset_intervals.
5185 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5187 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5188 current buffer (Bug#12387).
5190 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5192 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5194 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5196 Use a more backwards-compatible timer format (Bug#12430).
5197 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5198 vector element, not from the 4th, since PSECS is now at the end.
5199 (Fcurrent_idle_time): Doc fix.
5201 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5203 Function to mark objects and remove killed buffers at once.
5204 * alloc.c (discard_killed_buffers): Rename to ...
5205 (mark_discard_killed buffers) ... new name. Add marking
5206 of remaining objects. Fix comment. Adjust users.
5207 (mark_object): Do not touch frame buffer lists here.
5208 * frame.c (delete_frame): Reset frame buffer lists here.
5210 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5212 Better workaround for GNOME bug when --enable-gcc-warnings.
5213 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5214 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5215 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5217 Simplify SIGIO usage (Bug#12408).
5218 The code that dealt with SIGIO was crufty and confusing, e.g., it
5219 played tricks like "#undef SIGIO" but these tricks were not used
5220 consistently. Simplify mostly by not #undeffing standard symbols,
5221 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5222 or not as we please) rather than "defined SIGIO" (standard symbol
5223 that we probably shouldn't #undef).
5224 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5225 Modules that need it can include it.
5226 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5227 * dispextern.h (ignore_sigio): New decl.
5228 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5229 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5230 * emacs.c (shut_down_emacs):
5231 * keyboard.c (kbd_buffer_store_event_hold):
5232 Use ignore_sigio rather than invoking 'signal' directly.
5233 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5235 (FIONREAD, SIGIO): Do not #undef.
5236 (tty_read_avail_input): Use #error rather than a syntax error.
5237 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5238 for I_PIPE, used by SETUP_SLAVE_PTY.
5239 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5240 * sysdep.c (croak): Remove; no longer needed. This bit of
5241 temporary code, with Fred N. Fish's comment that it's temporary,
5242 has been in Emacs since at least 1992!
5243 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5244 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5245 * syssignal.h (croak): Remove decl.
5246 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5247 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5248 now that we're termios-only.
5249 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5250 * term.c (dissociate_if_controlling_tty): Use #error rather than
5253 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5254 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5255 to work around GNOME bug 683906.
5256 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5257 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5258 This works around GCC bug 54561.
5260 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5262 More fixes for 'volatile' and setjmp/longjmp.
5263 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5264 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5265 (png_load_body) [HAVE_PNG]:
5266 (jpeg_load_body) [HAVE_JPEG]:
5267 New function, with most of the old parent function's body.
5268 (png_load) [HAVE_PNG]:
5269 (jpeg_load) [HAVE_JPEG]:
5270 Invoke the new function, to avoid longjmp munging our locals.
5271 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5272 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5273 longjmp is passed 2, as the C standard doesn't guarantee this.
5274 Instead, store the failure code into mgr->failure_code.
5276 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5278 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5279 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5280 (syms_of_keyboard): Remove support for unread-command-char.
5282 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5284 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5285 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5286 violation. (Bug#12426)
5288 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5290 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5292 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5294 * eval.c: Add `inhibit-debugger'.
5295 (Qinhibit_debugger): New symbol.
5296 (call_debugger): Bind it instead of Qdebug_on_error.
5297 (maybe_call_debugger): Test Vinhibit_debugger.
5298 (syms_of_eval): Define inhibit-debugger.
5299 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5300 (syms_of_xdisp): Remove inhibit-debug-on-message.
5302 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5304 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5305 If a nonvolatile local variable is written before a _longjmp to
5306 the frame containing the variable, and is read after the _longjmp,
5307 the value read is indeterminate. Some local variables of type
5308 'struct handler' and 'struct catchtag' are used in this way, so
5309 mark each of their slots as volatile if the slot can be set before
5310 _longjmp and read afterwards.
5311 * lisp.h (struct handler): var and chosen_clause are now volatile.
5312 (struct catchtag): val, next, and pdlcount are now volatile.
5314 * bidi.c (bidi_push_it, bidi_pop_it):
5315 * fns.c (copy_hash_table):
5316 * image.c (define_image_type):
5317 * keyboard.c (kbd_buffer_store_event_hold):
5318 * process.c (Fprocess_send_eof):
5319 * xfaces.c (x_create_gc) [HAVE_NS]:
5320 * xgselect.c (xg_select):
5321 Prefer assignment to memcpy when either will do.
5323 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5324 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5325 time an item is removed. No need to mark this function 'inline';
5326 the compiler knows better than we do.
5328 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5330 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5331 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5332 to change_frame_size (Bug#12388).
5333 (windowDidResize:): Pass YES to updateFrameSize.
5335 * nsterm.h: Add delay parameter to updateFrameSize.
5337 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5339 Discard killed buffers from deleted window and frame objects.
5340 This reduces an amount of references to killed buffers and
5341 helps GC to reclaim them faster.
5342 * alloc.c (discard_killed_buffers): New function.
5343 (mark_object): Use it for deleted windows and frames.
5344 (mark_object): If symbol's value is set up for a killed buffer
5345 or deleted frame, restore its global binding.
5346 * data.c (swap_in_global_binding): Add GC notice.
5347 (swap_in_symval_forwarding): Use convenient set_blv_where.
5348 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5349 * window.h: ... to here.
5351 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5353 Convenient macro to check whether the buffer is live.
5354 * buffer.h (BUFFER_LIVE_P): New macro.
5355 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5356 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5358 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5360 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5361 composition cases (Bug#12364).
5363 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5364 overhang of succeeding glyphs overlapping box cursor.
5366 * w32term.c (x_draw_glyph_string): Likewise.
5368 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5370 Simplify, document, and port floating-point (Bug#12381).
5371 The porting part of this patch fixes bugs on non-IEEE platforms
5372 with frexp, ldexp, logb.
5373 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5375 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5376 support, by removing commented-out code and briefly listing the
5377 C89 functions excluded. The commented-out stuff was confusing
5378 maintenance, e.g., we thought we needed cbrt but it was commented out.
5379 (logb): Remove decl; no longer needed.
5380 (isfinite): New macro, if not already supplied.
5381 (isnan): Don't replace any existing macro.
5382 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5383 are present on all C89 platforms.
5384 (Ffrexp): Do not special-case zero, as frexp does the right thing
5386 (Flogb): Do not use logb, as it doesn't have the desired meaning
5387 on hosts that use non-base-2 floating point. Instead, stick with
5388 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5389 frexp, to avoid getting an unspecified result.
5391 * xdisp.c (Qinhibit_debug_on_message): Now static.
5393 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5395 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5396 NSBezierPath (Bug#12131).
5398 2012-09-10 Chong Yidong <cyd@gnu.org>
5400 * fns.c (Fdelq, Fdelete): Doc fix.
5402 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5404 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5405 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5407 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5409 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5410 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5413 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5415 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5416 left fringe if the window has a left margin. This avoids leaving
5417 traces of the cursor because its leftmost pixel is not drawn over.
5419 * dispnew.c (update_window_line): When the left margin area of a
5420 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5421 that screen line. (Bug#12277)
5423 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5425 Assume C89 or later for math functions (Bug#12381).
5426 This simplifies the code, and makes it a bit smaller and faster,
5427 and (most important) makes it easier to clean up signal handling
5428 since we can stop worring about floating-point exceptions in
5429 library code. That was a problem before C89, but the problem
5430 went away many years ago on all practical Emacs targets.
5431 * data.c, image.c, lread.c, print.c:
5432 Don't include <math.h>; no longer needed.
5433 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5434 might be autoconfigured, as that never happens.
5436 * doprnt.c (DBL_MAX_10_EXP):
5437 * print.c (DBL_DIG):
5438 Remove. C89 or later always defines these.
5439 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5440 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5441 (arith_error, domain_error, domain_error2):
5442 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5443 no longer needed -- we simply return what C returns. All uses removed.
5444 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5446 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5447 Remove. All uses expanded, as these macros are no longer used
5448 more than once and are now more trouble than they're worth.
5449 (Ftan): Use tan, not sin / cos.
5450 (Flogb): Assume C89 frexp.
5451 (fmod_float): Assume C89 fmod.
5452 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5453 (init_floatfns): Remove. All uses removed.
5455 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5457 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5458 compositeToPoint for OSX < 10.6 (Bug#12390).
5460 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5462 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5463 This produces more-accurate results.
5465 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5467 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5468 changes (Bug#12088).
5470 2012-09-08 Chong Yidong <cyd@gnu.org>
5472 * syntax.c (Fstring_to_syntax): Doc fix.
5474 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5476 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5477 in the internal border.
5478 (x_set_window_size): Remove static variables and their usage.
5479 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5480 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5481 Remove fringe/internal border adjustment (Bug#11052).
5482 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5483 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5484 (ns_fix_rect_ibw): Remove.
5485 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5486 (ns_dumpglyphs_box_or_relief): Ditto.
5487 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5489 (ns_dumpglyphs_image): Ditto.
5490 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5492 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5493 their usage. Add fringe_extended_p and its use as in other terms.
5494 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5495 scroll bar was removed.
5496 (updateFrameSize): New function.
5497 (windowDidResize): Move code to updateFrameSize and call it.
5499 * nsterm.h (EmacsView): Add updateFrameSize.
5501 2012-09-07 Chong Yidong <cyd@gnu.org>
5503 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5505 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5507 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5509 More signal-handler cleanup (Bug#12327).
5510 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5511 Problem introduced when merging patches. Noted by Eli Zaretskii in
5512 <http://bugs.gnu.org/12327#67>.
5513 * floatfns.c: Comment fix.
5514 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5515 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5516 and anyway the declaration is harmless even if SIGDANGER is not defined.
5517 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5518 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5519 source files not surprisingly expected syssignal.h to define, or
5520 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5521 Include <sys/ioctl.h>, for FIONREAD.
5522 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5523 This eliminates a problem whereby other files mysteriously had
5524 to include "syssignal.h" before including "systty.h" if they
5525 wanted to use "#ifdef SIGIO".
5527 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5529 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5531 * w32.c (sigemptyset): Empty the set.
5532 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5534 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5536 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5538 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5539 (mark_object): Likewise for frame objects.
5541 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5543 * syssignal.h (handle_on_main_thread): Always declare,
5544 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5545 This ports to platforms without HAVE_PTHREAD.
5547 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5549 Signal-handler cleanup (Bug#12327).
5550 Emacs's signal handlers were written in the old 4.2BSD style with
5551 sigblock and sigmask and so forth, and this led to some
5552 inefficiencies and confusion. Rewrite these to use
5553 pthread_sigmask etc. without copying signal sets around. Also,
5554 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5555 'signal', and instead use functions that do not attempt to take
5556 over the system name space. This patch causes Emacs's text
5557 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5558 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5559 Do not include <signal.h> or "syssignal.h", as these
5560 modules do not use signals.
5561 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5562 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5563 Do not include <signal.h>, as "syssignal.h" does that for us now.
5564 * atimer.c (sigmask_atimers): New function.
5565 (block_atimers, unblock_atimers): New functions,
5566 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5568 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5569 no longer needed here.
5570 * emacs.c (main): Inspect existing signal handler with sigaction,
5571 so that there's no need to block and unblock SIGHUP.
5572 * sysdep.c (struct save_signal): New member 'action', replacing
5573 old member 'handler'.
5574 (save_signal_handlers, restore_signal_handlers):
5575 Use sigaction instead of 'signal' to save and restore.
5576 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5577 New function. All users of 'signal' modified to use set_sighandler
5578 if they're writeonly, and to use sys_signal if they're read+write.
5579 (emacs_sigaction_init, forwarded_signal): New functions.
5580 (sys_signal): Remove. All uses replaced by calls to sigaction
5581 and emacs_sigaction_init, or by direct calls to 'signal'.
5582 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5583 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5584 all uses replaced by pthread_sigmask etc. calls.
5585 * syssignal.h: Include <signal.h>.
5586 (emacs_sigaction_init, forwarded_signal): New decls.
5587 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5588 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5589 (sigmask, sys_sigmask): Remove; no longer needed.
5590 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5591 (sigblock, sigunblock, sigfree):
5592 (sigsetmask) [!defined sigsetmask]:
5593 Remove. All uses replaced by pthread_sigmask.
5594 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5595 no longer need to be replaced, and its typical old uses
5596 are now done via emacs_sigaction_init and sigaction.
5597 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5598 (sys_sigdel): Remove; unused.
5599 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5601 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5603 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5604 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5606 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5608 Explicitly mark buffer_defaults and buffer_local_symbols.
5609 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5610 mark_local_symbols here.
5611 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5612 since special buffers aren't marked here any more.
5613 (allocate_buffer): Chain new buffer with all_buffers here...
5614 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5616 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5617 (syms_of_buffer): Remove staticpro of the above.
5618 (init_buffer_once): Set names for buffer_defaults and
5619 buffer_local_symbols.
5621 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5623 Use bool for booleans in font-related modules.
5624 * font.c (font_intern_prop, font_style_to_value)
5625 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5626 (generate_otf_features, font_check_otf_features, font_check_otf)
5627 (font_match_p, font_list_entities, font_at):
5628 * fontset.c (fontset_id_valid_p, reorder_font_vector
5629 (fontset_find_font, Fset_fontset_font)
5630 (face_suitable_for_char_p) [0]:
5631 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5632 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5633 (m17n_flt_initialized, ftfont_shape_by_flt):
5634 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5635 * nsfont.m (nsfont_draw):
5636 * w32font.c (w32font_draw):
5637 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5638 Use bool for booleans.
5639 * font.h: Adjust to above API changes.
5640 (struct font, struct font_driver, struct font_driver_list):
5641 Use bool for booleans.
5642 (struct font): Remove useless member encoding_type.
5644 * fontset.c, xftfont.c: Omit unnecessary static decls.
5646 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5648 * alloc.c (mark_object): Revert window marking code
5649 since it's unsafe for the Fset_window_configuration.
5651 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5653 Fix race conditions with signal handlers and errno (Bug#12327).
5654 Be more systematic about preserving errno whenever a signal
5655 handler returns, even if it's not in the main thread. Do this by
5656 renaming signal handlers to distinguish between signal delivery
5657 and signal handling. All uses changed.
5658 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5659 * data.c (deliver_arith_signal): Rename from arith_error.
5660 * dispnew.c (deliver_window_change_signal): Rename from
5661 window_change_signal.
5662 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5663 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5664 * keyboard.c (deliver_input_available_signal): Rename from
5665 input_available_signal.
5666 (deliver_user_signal): Rename from handle_user_signal.
5667 (deliver_interrupt_signal): Rename from interrupt_signal.
5668 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5669 (deliver_child_signal): Rename from sigchld_handler.
5670 * atimer.c (handle_alarm_signal):
5671 * data.c (handle_arith_signal):
5672 * dispnew.c (handle_window_change_signal):
5673 * emacs.c (handle_fatal_signal, handle_danger_signal):
5674 * keyboard.c (handle_input_available_signal):
5675 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5676 * process.c (handle_pipe_signal, handle_child_signal):
5677 New functions, with the actual signal-handling code taken from the
5678 original respective signal handlers, sans the sporadic attempts to
5679 preserve errno, since that's now done by handle_on_main_thread.
5680 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5681 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5682 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5684 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5685 Move initialization of main_thread to sysdep.c's init_signals.
5686 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5687 our usage, and simplifies the mainline code.
5688 (record_child_status_change): New static function, as a helper
5689 for handle_child_signal, and with most of the old child handler's
5691 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5692 (handle_child_signal): Use the above.
5693 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5694 Moved here from emacs.c.
5695 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5696 code moved here from emacs.c's main function.
5697 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5698 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5699 This lets callers save and restore errno properly.
5701 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5703 Remove redundant or unused things here and there.
5704 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5705 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5706 * editfns.c (Fcompare_buffer_substrings): Likewise.
5707 * frame.h (struct terminal, struct font_driver_list):
5708 Remove redundant declarations.
5709 * window.h (Qleft, Qright): Likewise.
5711 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5713 Do not mark objects from deleted buffers, windows and frames.
5714 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5715 (mark_object): Likewise for windows and frames.
5717 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5719 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5720 buffer_defaults and buffer_local_symbols as valid objects.
5721 Return special value to denote them.
5723 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5725 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5726 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5727 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5728 (file_name_absolute_p, Fsubstitute_in_file_name):
5729 (check_executable, check_writable, Ffile_accessible_directory_p)
5730 (Fset_file_selinux_context, Fdefault_file_modes)
5731 (Finsert_file_contents, choose_write_coding_system)
5732 (Fwrite_region, build_annotations, a_write, e_write)
5734 * filelock.c (boot_time_initialized, get_boot_time)
5735 (get_boot_time_1, lock_file_1, within_one_second):
5736 * floatfns.c (in_float):
5737 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5738 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5739 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5740 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5741 * window.c (compare_window_configurations):
5742 Use bool for booleans.
5743 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5744 (Fdefault_file_modes): Now mode_t, not int, for modes.
5745 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5746 (internal_delete_file): Now returns void, not a (boolean) int,
5747 since nobody was looking at the return value.
5748 * lisp.h, window.h: Adjust to above API changes.
5750 * xdisp.c (set_message): Simplify and reindent last change.
5752 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5754 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5756 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5758 * eval.c (call_debugger): Make the function non-static so that we
5759 can call it from set_message.
5761 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5762 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5764 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5766 Give more-useful info on a fatal error (Bug#12328).
5767 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5768 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5769 of doing the work ourselves.
5770 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5771 do most of the work.
5772 (fatal_error_backtrace): New function, taken from the guts
5773 of the old fatal_error_signal, but with a new option to output
5775 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5776 info about the signal than just its number.
5777 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5778 * sysdep.c: Include <execinfo.h>
5779 (emacs_backtrace): New function, taken partly from the previous
5780 code of the 'die' function.
5781 (emacs_abort): Call fatal_error_backtrace rather than abort.
5783 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5785 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5786 eager (load-time) macro-expansion.
5787 * lisp.mk (lisp): Add macroexp.
5789 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5791 Simplify redefinition of 'abort' (Bug#12316).
5792 Do not try to redefine the 'abort' function. Instead, redo
5793 the code so that it calls 'emacs_abort' rather than 'abort'.
5794 This removes the need for the NO_ABORT configure-time macro
5795 and makes it easier to change the abort code to do a backtrace.
5796 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5797 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5798 Remove; sysdep.c's emacs_abort now takes its place.
5799 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5800 'abort' changed to use 'emacs_abort'.
5801 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5802 (abort) [!defined abort]: Rename to ...
5803 (emacs_abort): ... new name.
5804 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5805 the place of the old 'abort' in emacs.c.
5806 * w32.c, w32fns.c (abort): Do not #undef.
5807 * w32.c (emacs_abort): Rename from w32_abort.
5809 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5811 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5812 offsets[j].dv, since the y axis of the screen coordinates points
5813 down, while the y axis of the font definition coordinates points
5814 up. This fixes display of Arabic diacritics such as KASRA and
5815 KASRATAN. (Bug#11860)
5817 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5819 Be more systematic about _setjmp vs setjmp.
5820 * alloc.c (test_setjmp, mark_stack):
5821 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5822 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5823 (png_load, my_error_exit, jpeg_load):
5824 * process.c (send_process_trap, send_process):
5825 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5826 The underscored versions are up to 30x faster on some hosts.
5827 Formerly, the code used setjmp+longjmp sometimes and
5828 _setjmp+_longjmp at other times, with no particular reason to
5829 prefer setjmp+longjmp.
5831 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5833 Fix minor problem found by static checking.
5834 * buffer.c (Fdelete_all_overlays): Return nil.
5836 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5838 * buffer.c (Fdelete_all_overlays): New function.
5840 2012-09-03 Chong Yidong <cyd@gnu.org>
5842 * gtkutil.c: Add extern decl for Qxft.
5844 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5846 * emacs.c, eval.c: Use bool for boolean.
5847 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5848 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5849 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5850 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5851 (main, decode_env_path, Fdaemon_initialized):
5852 * eval.c (call_debugger, Finteractive_p, interactive_p):
5853 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5854 (maybe_call_debugger, Fbacktrace):
5855 * process.c (read_process_output, exec_sentinel):
5856 Use bool for booleans.
5857 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5858 All callers changed.
5859 * eval.c (interactive_p): Omit always-true boolean argument
5860 EXCLUDE_SUBRS_P. All callers changed.
5861 * dispextern.h, lisp.h: Reflect above API changes.
5862 * firstfile.c (dummy): Use the address of 'main', whose signature
5863 won't change, instead of the address of 'initialize', whose
5864 signature just changed from int to bool.
5865 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5866 * msdos.c (fatal_error_in_progress): ... from here.
5867 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5869 (redisplay_internal, unwind_redisplay): Simply clear
5870 REDISPLAYING_P when unwinding, instead of saving its previous,
5871 always-false value and then restoring it.
5873 Clean up some extern decls.
5874 Mostly, this hoists extern decls out of .c files and into .h files.
5875 That way, we're more likely to catch errors if the interfaces change.
5876 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5877 declare xg_mark_data.
5878 * dispextern.h (x_frame_parm_handlers):
5880 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5881 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5882 (Qultra_bold, Qoblique, Qitalic):
5883 Move extern decl here from .c file.
5884 * alloc.c (xg_mark_data) [USE_GTK]:
5886 * eval.c (Qlexical_binding):
5887 * fns.c (time) [!HAVE_UNISTD_H]:
5888 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
5889 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

5891 * lread.c (Qinternal_interpreter_environment):
5892 * minibuf.c (Qbuffer):
5893 * process.c (QCfamily, QCfilter):
5894 * widget.c (free_frame_faces):
5895 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5896 * xfont.c (x_clear_errors):
5897 * xterm.c (x_frame_parm_handlers):
5898 Remove now-redundant extern decls.
5899 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5900 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5902 * xfaces.c: Remove unnecessary static decls.
5903 * xterm.c (updating_frame): Remove decl of nonexistent object.
5905 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5906 when building globals.h, as the objects that are not built on
5907 this host are not needed to compile C files on this host.
5909 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5911 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5913 * frame.h: Add missing prototype for x_wm_set_size_hint.
5915 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5917 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

5919 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5920 (Fsubstitute_command_keys):

5923 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)

5925 (make_buffer_string, make_buffer_string_both)
5926 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
5927 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

5963 offset adjustment values separately for each cluster. (Bug#11860)
5965 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5966 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5967 about implicit conversions from integer to pointer.

6025 window system declarations.
6027 * frame.h: Move common functions here: set_frame_menubar,
6028 x_set_window_size, x_sync, x_get_focus_frame,
6029 x_set_mouse_position, x_set_mouse_pixel_position,
6030 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6061 * term.c (mark_ttys): Remove.
6062 (init_tty): Safely initialize 'top_frame' slot with Qnil.

6086 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6087 for GCC 4.7.1 x86-64.
6089 2012-08-30 Glenn Morris <rgm@gnu.org>
6091 * lread.c (init_lread): For out-of-tree builds, only add the
6092 source directory's site-lisp dir to the load-path if it exists,
6093 consistent with in-tree builds. (Bug#12302)
6095 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6329 It was meant to be temporary and it often doesn't work,
6330 because when IDX has side effects the behavior of IDX==IDX
6331 is undefined. See Stefan Monnier in
6332 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

6345 says no events are pending.
6346 (gfds, gfds_size): Remove these static vars.

6348 All uses and decls removed.

6378 Use bool for booleans, instead of int.
6379 * lisp.h, process.h: Adjust prototypes to match above changes.
6380 * callint.c (Fcall_interactively): Don't assume the mark's
6381 offset fits in 'int'.
6383 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6385 * buffer.c, buffer.h: Use bool for boolean.
6386 * buffer.c (reset_buffer_local_variables)
6387 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6388 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6389 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6390 (overlay_touches_p, overlay_strings, Foverlay_put)
6391 (report_overlay_modification, call_overlay_mod_hooks):
6392 (mmap_enlarge, mmap_set_vars):
6393 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6394 Use bool for booleans, instead of int.
6395 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6396 since the 1-or-0 return value is always ignored anyway.
6397 (mmap_initialized_p):
6398 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6399 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6401 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6403 * bidi.c: Use bool for boolean.
6404 This is a bit more readable, and makes the text segment of bidi.o
6405 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6406 Presumably it's faster too.
6407 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6409 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6410 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6411 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6412 (bidi_explicit_dir_char, bidi_level_of_next_char)
6413 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6414 Use bool for booleans, instead of int.
6415 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6416 (bidi_unshelve_cache): Adjust decls to match code.
6418 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6420 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6423 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6425 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6426 * atimer.h: Include <stdbool.h>.
6428 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6430 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6431 compile time tests instead of run time tests on systems that do
6433 (FRAME_MAC_P): Remove leftover from deleted code.
6434 * frame.c (syms_of_frame): Remove leftover from deleted code.
6436 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6438 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6440 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6442 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6443 Otherwise, the compiler complains about (A?B:C) where B is void
6444 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6445 (fontset_add): Return void, for FONTSET_ADD.
6447 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6449 * alloc.c: Use bool for booleans.
6450 (gc_in_progress, abort_on_gc)
6451 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6452 (dont_register_blocks) [GC_MALLOC_CHECK]:
6453 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6454 (check_string_bytes, make_specified_string, memory_full)
6455 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6456 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6457 (mark_stack, valid_pointer_p, make_pure_string)
6458 (Fgarbage_collect, survives_gc_p, gc_sweep):
6459 Use bool for booleans, instead of int.
6460 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6461 Remove unused local.
6462 * alloc.c (PURE_POINTER_P):
6463 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6464 * editfns.c (Fformat):
6465 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6467 * fns.c (sweep_weak_table):
6468 * lisp.h (suppress_checking, push_message, survives_gc_p)
6469 (make_pure_string, gc_in_progress, abort_on_gc):
6470 * lread.c (readchar, read1):
6471 * print.c (Fprin1_to_string):
6472 * xdisp.c (push_message):
6473 Use bool for booleans affected directly or indirectly by
6476 Make recently-introduced setters macros.
6477 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6478 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6479 (set_fontset_default, set_fontset_fallback): Rename from their
6480 upper-case counterparts, and make them functions rather than macros.
6481 This is more consistent with the other recently-introduced setters.
6482 These don't need to be inline, since they're local.
6484 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6486 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6487 the loop (Bug#12247).
6489 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6491 * lisp.h (vcopy): Use memcpy rather than our own loop.
6492 This fixes a performance regression introduced by the recent
6493 addition of vcopy. This means 'vcopy' will need to be modified
6494 for a copying collector, but that's OK. Also, tighten the
6495 checking in the assertion.
6497 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6499 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6500 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6501 non-base glyph for the width of the base character, according to
6502 what x_draw_composite_glyph_string_foreground expects.
6503 Generate WADJUST value according to composition_gstring_width's
6504 expectations, to produce correct width of the composed character.
6505 Reverse the sign of the DU offset produced by ScriptPlace.
6507 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6509 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6511 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6513 Avoid direct writes to contents member of struct Lisp_Vector.
6514 * lisp.h (vcopy): New function to copy data into vector.
6515 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6516 * fns.c (Ffillarray): Use ASET.
6517 * keyboard.c (timer_check_2): Use AREF and ASET.
6518 (append_tool_bar_item, Frecent_keys): Use vcopy.
6519 * lread.c (read_vector): Use ASET.
6520 * msdos.c (Frecent_doskeys): Use vcopy.
6521 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6522 (Finternal_merge_in_global_face): Use ASET and vcopy.
6523 * xfont.c (xfont_list_pattern): Likewise.
6525 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6527 * window.c (Fwindow_point): For the selected window always return
6528 the position of its buffer's point.
6529 (Fset_window_point): For the selected window always go in its
6530 buffer to the specified position.
6532 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6534 Setter macros for fontsets.
6535 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6536 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6537 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6540 2012-08-20 Glenn Morris <rgm@gnu.org>
6542 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6543 Don't assume that `ln -f' works.
6545 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6547 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6548 and later about non-assignments with no effect. See discussion at
6549 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6552 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6554 Inline setter functions for Lisp_Objects slots of struct specbinding.
6555 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6558 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6560 * window.c (select_window): Always make selected window's buffer
6563 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6565 Use AREF and ASET for docstrings of category tables.
6566 * category.h (CATEGORY_DOCSTRING): Use AREF.
6567 (SET_CATEGORY_DOCSTRING): Use ASET.
6568 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6570 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6572 Inline setter functions for hash table members.
6573 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6574 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6575 (set_hash_key_and_value, set_hash_index, set_hash_next)
6576 (set_hash_hash): New functions.
6577 * charset.c, fns.c: Adjust users.
6579 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6581 Inline getter and setter functions for per-buffer values.
6582 * buffer.h (per_buffer_default, set_per_buffer_default)
6583 (per_buffer_value, set_per_buffer_value): New functions.
6584 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6585 * buffer.c, data.c: Adjust users.
6587 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6589 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6591 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6593 Rely on <config.h> + <unistd.h> to declare 'environ',
6594 as gnulib does this if the system doesn't.
6595 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6596 Remove declaration. MS-Windows declares it on stdlib.h which is
6597 included by conf_post.h.
6598 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6599 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6600 * vm-limit.c: Include <unistd.h>, for 'environ'.
6602 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6603 (start_of_data): Remove decl; mem-limits.h provides it.
6605 * xdisp.c (handle_invisible_prop): Make it a bit faster
6606 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6608 2012-08-19 Chong Yidong <cyd@gnu.org>
6610 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6613 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6615 * .gdbinit: Use call instead of set when calling a function in the
6618 * data.c (set_internal): Don't use set_blv_found.
6619 (Fkill_local_variable): Likewise.
6621 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6623 * nsfont.m (ns_ascii_average_width): Ensure the string
6624 ascii_printable is initialized with a null-terminated character
6625 array. Otherwise, it can contain undesired extra characters.
6627 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6629 port new setting code to Sun C 5.8 2005/10/13
6630 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6631 Return void, not Lisp_Object. Otherwise, the compiler
6632 complains about (A?B:C) where B is void and C is Lisp_Object
6633 when compiling CHAR_TABLE_SET, due to the recent change to
6634 the API of sub_char_table_set_contents.
6636 2012-08-18 Chong Yidong <cyd@gnu.org>
6638 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6639 for the string case (Bug#3874).
6641 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6643 * buffer.h (BSET): Remove (Bug#12215).

6713 New setter functions.
6715 * termhooks.h (TSET): Remove (Bug#12215).

6722 are compiled into code.
6723 (tset_param_alist): New setter function.
6725 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
6727 * keyboard.h (KSET): Remove (Bug#12215).

6760 A few more naming-convention fixes for getters and setters.
6761 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,
6762 and rename from buffer_overlays_set_before.
6763 (set_buffer_overlays_after): Move here from buffer.h, and rename
6764 from buffer_overlays_set_after.
6765 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

6792 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
6793 "set_char_table_parent (char_table, parent);".
6794 The old version was confusing because it used the same name
6795 'parent' for two different things.
6797 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6799 Functions to get and set Lisp_Object fields of buffer-local variables.

7466 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7467 * w32.c (init_environment): Change the default values of many
7468 environment variables in dflt_envvars[] to NULL, to avoid pushing
7469 them into environment when they were not already defined.
7470 Remove the code that deletes site-lisp subdirectories from the default
7471 value of EMACSLOADPATH, as it is no longer needed.
7472 (check_windows_init_file): Now external, not static.
7473 Use Vload_path as is, without adding anything, as this function is now
7474 called when Vload_path is already set up.
7476 * w32.h (check_windows_init_file): Add prototype.
7478 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7485 installation tree, as appropriate.
7487 * callproc.c (init_callproc_1): Call decode_env_path instead of
7488 doing its equivalent by hand.

7506 Remove unnecessary casts involving pointers.
7507 These casts are no longer needed now that we assume C89 or later,

7521 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7522 Remove unnecessary pointer casts.
7523 * alloc.c (record_xmalloc): New function.
7524 * lisp.h (record_xmalloc): New decl.
7525 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7526 more like a function. This is because the pointer cast is not
7527 needed. All uses changed.
7528 * print.c (print_string, print_error_message): Avoid length recalc.
7530 Improve fix for macroexp crash with debugging (Bug#12118).
7531 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7532 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7533 not supposed to be invoked from the garbage collector.

7535 (gc_aset): New function, which is like ASET but can be
7536 used in the garbage collector.

7565 with addition of handling of symlinks and support for 'lstat'.
7566 If possible, get file's attributes and security information by
7567 handle, not by name. Produce S_IFLNK bit for symlinks, when
7568 called from 'lstat'.
7569 (stat, lstat): New functions, call 'stat_worker'.
7570 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7571 symlinks when the underlying filesystem supports them.
7573 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7575 Fix macroexp crash on Windows with debugging (Bug#12118).
7576 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7577 checking subscripts; problem introduced with the recent
7578 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7579 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7580 since it's used in non-static inline functions now.
7582 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7583 Don't assume buffer size fits in 'int'. Remove unused local.

7603 * composite.c (COMPOSITE_INLINE):
7604 * dispnew.c (DISPEXTERN_INLINE):
7605 * sysdep.c (SYSTIME_INLINE):
7606 Define to EXTERN_INLINE, so that the corresponding functions
7607 are compiled into code.
7608 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7609 (INLINE_HEADER_END): New macros.
7610 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7630 hard-coding the path separator.
7632 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7634 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7635 This how ASET and AREF are supposed to work, and makes
7636 it easier to think about future improvements. See
7637 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7638 * charset.h (set_charset_attr): New function.

8141 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8142 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8143 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8144 not be usable in #if. This simplifies things.

8153 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8154 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8155 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8156 Adjust to changes in lisp.h and emacs.c, by using
8157 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8158 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8159 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8160 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8161 instead of gdb_valbits.
8162 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8163 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8164 instead of gdb_array_mark_flag.
8165 (xboolvector): Get size from $->size, not $->header.size.
8166 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8167 (xreload, hook-run, hookpost-run): Remove.
8168 * emacs.c: Include <verify.h>.
8169 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

8173 (gdb_USE_LSB_TAG): New enum constants.
8174 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8175 Also define these as enum constants, so they're visible to GDB.
8176 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8177 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8178 as constants, so they're visible to GDB.
8179 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8180 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8181 Now enum constants, not macros, so they're visible to GDB.
8182 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8183 more convenient now. All uses changed.
8184 (VALMASK) [USE_LSB_TAG]: Also define in this case.

8197 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8199 Use typedef for EMACS_INT, EMACS_UINT.
8200 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8201 than macros. This simplifies debugging in the usual case, since
8202 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8203 and it allows expressions involving EMACS_INT casts.
8204 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8206 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8222 (init_buffer_once): Initialize indirection counters of
8223 buffer_defaults and buffer_local_symbols (for sanity and safety).
8225 2012-07-24 Eli Zaretskii <eliz@gnu.org>

8256 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8258 Swap buffer text indirection counters in Fbuffer_swap_text.
8259 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8260 This avoids crash reported by Christoph Scholtes at
8261 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8263 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8265 * nsmenu.m (Popdown_data): New struct.

8288 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8290 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8291 as it's limited by the amount of memory, not by INT_MAX.
8293 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8295 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

8452 * keyboard.c (command_loop_1): Set it.
8453 * cmds.c (Fself_insert_command): Use it to only remove boundaries that

9038 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9039 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9040 not functions. All uses rewritten to use the following, respectively:
9041 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9042 (add_emacs_time, sub_emacs_time): New functions.
9043 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9069 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9070 * nsterm.m (ns_term_init):
9071 Avoid the need for strncpy, by using build_string or
9072 make_unibyte_string directly. Use dtoastr, not snprintf.
9073 * process.c (Fmake_network_process): Diagnose service names that
9074 are too long, rather than silently truncating them or creating
9075 non-null-terminated names.
9076 (Fnetwork_interface_info): Likewise, for interface names.
9077 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9078 Prefer sprintf to strncat.
9079 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

9085 Clarify fallback case.
9087 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9089 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9090 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9091 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9092 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

9105 Optimize pure C strings initialization.
9106 * lisp.h (make_pure_string): Fix prototype.
9107 (build_pure_c_string): New function, defined as static inline. This
9108 provides a better opportunity to optimize away calls to strlen when
9109 the function is called with compile-time constant argument.
9110 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9111 argument, adjust users accordingly. Use build_pure_c_string where
9113 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9114 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9115 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9117 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9119 Avoid calls to strlen in miscellaneous functions.
9120 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9121 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9122 * lread.c (openp): Likewise.

9126 Avoid calls to strlen in path processing functions.
9127 * fileio.c (file_name_as_directory): Add comment. Change to add
9128 srclen argument and return the length of result. Adjust users

9132 Adjust users accordingly.
9133 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9135 2012-07-10 Glenn Morris <rgm@gnu.org>
9137 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9142 * s/gnu.h (DATA_START): Move definitions to configure.
9144 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9145 We include usg5-4-common.h, which defines them both.
9147 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9148 O_RDONLY already includes it).
9150 Stop ns builds setting the EMACSLOADPATH environment variable.
9151 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9152 Now it does not set EMACSLOADPATH, just returns the load-path string.
9153 * nsterm.h: Update accordingly.
9154 * lread.c [HAVE_NS]: Include nsterm.h.
9155 (init_lread) [HAVE_NS]: Use ns_load_path.

9158 2012-07-09 Glenn Morris <rgm@gnu.org>
9160 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9161 since the included bsd-common.h does so.
9163 Stop ns builds setting the EMACSPATH environment variable.
9164 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9165 (ns_init_paths): Do not set EMACSPATH.
9166 * nsterm.h (ns_exec_path): Add it.
9167 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9170 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9172 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9174 * process.c (wait_reading_process_output): 'waitchannels' was unset
9175 when read_kbd || !NILP (wait_for_cell); fix this.
9177 Add GCC-style 'const' attribute to functions that can use it.
9178 * character.h (char_resolve_modifier_mask):
9179 * keyboard.h (make_ctrl_char):
9180 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9189 Add decls with ATTRIBUTE_CONST.
9191 Minor improvements to make_formatted_string.
9192 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9193 where int is good enough, as vsprintf returns an int.
9194 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9196 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9198 Use make_formatted_string to avoid double length calculation.
9199 * lisp.h (make_formatted_string): New prototype.
9200 * alloc.c (make_formatted_string): New function.
9201 * buffer.c (Fgenerate_new_buffer_name): Use it.

9223 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9225 Move marker debugging code under MARKER_DEBUG.
9226 * marker.c (MARKER_DEBUG): Move marker debugging code under
9227 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9228 for bootstrap with --enable-checking (~3x slowdown reported
9229 by Juanma Barranquero <lekktu@gmail.com>).
9230 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9232 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9234 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9235 See <http://bugs.gnu.org/11825#29>.
9237 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9239 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9240 has no font, use the frame's font. (Bug#11813)
9241 (display_line): Add commentary about displaying truncation glyphs
9243 (produce_special_glyphs): Move here from term.c.
9245 * term.c (produce_special_glyphs): Move to xdisp.c.
9247 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9250 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9252 * xdisp.c (display_line): Avoid warning about implicit declaration
9255 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9257 * lisp.h: Remove empty conditional.
9259 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9261 * lread.c (load_path_check): Now static.
9263 Fix some minor --with-ns problems found by static checking.
9264 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9265 (x_set_font) [!HAVE_X_WINDOWS]:
9266 * image.c (xpm_load_image) [HAVE_NS]:
9267 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9268 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9269 Remove unused local.
9270 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9271 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9272 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9273 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9274 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9275 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9276 Fix pointer signedness problem.
9277 * xfaces.c (FRAME_X_FONT_TABLE):
9278 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9280 2012-07-07 Glenn Morris <rgm@gnu.org>
9282 * lread.c (load_path_check): New function, split from init_lread.
9283 (init_lread): Reorganize. Motivation:
9284 If EMACSLOADPATH is set, check/warn about that rather than the
9285 defaults, which we are not going to use. Hence we can remove
9286 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9287 Don't warn if site-lisp directories are missing.
9288 If not installed, start from a blank load-path, since
9289 PATH_LOADSEARCH refers to the eventual installation directories.
9291 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9293 Support truncation and continuation glyphs on GUI frames, when
9294 fringes are disabled. (Bug#11832)
9295 * xdisp.c (init_iterator): Get dimensions of truncation and
9296 continuation glyphs even if on GUI frames.
9297 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9298 or both, are absent.
9299 (start_display, move_it_in_display_line_to): Handle the case of a
9300 GUI frame without a fringe to display continuation or truncation
9302 (insert_left_trunc_glyphs): Support GUI frames: make sure
9303 truncation glyphs overwrite enough glyphs from the current line to
9304 have sufficient space in pixels.
9305 (display_line): Support truncation and continuation glyphs on GUI
9306 frames. If some spare pixels are left on the line after inserting
9307 the truncation glyphs, fill that space with a stretch glyph of a
9308 suitably computed width.
9310 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9311 produce_glyphs, to support GUI sessions.
9313 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9315 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9317 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9319 Do not require float-time's arg to fit in time_t (Bug#11825).
9320 This works better on hosts where time_t is unsigned, and where
9321 float-time is applied to the (negative) difference between two times.
9322 * editfns.c (decode_time_components): Last arg is now double *,
9323 not int *, and means to store all the result as a double, without
9324 worrying about whether the seconds part fits in time_t.
9325 All callers changed.
9326 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9327 All callers changed.
9328 (Ffloat_time): Do not fail merely because the specified time falls
9329 outside of time_t range.
9331 2012-07-07 Glenn Morris <rgm@gnu.org>
9333 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9334 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9335 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9337 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9339 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9340 Update dependencies.
9342 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9344 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9346 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

9348 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9349 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9350 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9351 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9353 * xfont.c (compare_font_names): Redo to omit the need for casts.
9355 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9357 * xfns.c (Fx_change_window_property): Doc fix.
9358 * w32fns.c (Fx_change_window_property): Doc fix.
9360 * w32fns.c (Fx_window_property): Accept the same arguments as the
9361 X Windows version. Doc fix.
9362 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9364 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9365 Eli Zaretskii <eliz@gnu.org>
9367 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9368 Windows-specific code from nt/config.nt moved here.
9369 Obsolete settings removed.
9371 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9373 * process.c: Avoid unnecessary calls to gettime.
9374 (wait_reading_process_output): Don't get the time of day
9375 when gobbling data immediately and not waiting, as there's no need
9376 for it in that case. This removes a FIXME.
9378 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9380 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9381 is defined (Bug#11768).
9383 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9385 Fix marker debugging code.
9386 * marker.c (byte_char_debug_check): Do not perform the check
9387 if buffer is not multibyte.
9388 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9389 Call byte_char_debug_check with correct arguments.
9391 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9393 Compile marker debugging code only if ENABLE_CHECKING is defined.
9394 * marker.c (byte_char_debug_check, count_markers):
9395 Use only if ENABLE_CHECKING is defined.
9396 (byte_debug_flag): Remove.
9397 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9398 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9400 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9402 Avoid code repetition in marker-related functions.
9403 * marker.c (attach_marker): New function.
9404 (Fset_marker, set_marker_restricted, set_marker_both)
9405 (set_marker_restricted_both): Use it.
9406 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9407 Consistently rename charno to charpos.
9408 (marker_position): Add eassert.
9409 (marker_byte_position): Convert to eassert.
9411 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9413 Simplify list operations in unchain_overlay and unchain_marker.

9422 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9423 * composite.c (autocmp_chars): Likewise.
9424 * editfns.c (buildmark): Remove.
9425 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9426 (save_restriction_save): Use build_marker.
9427 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9428 * window.c (save_window_save): Likewise.
9430 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9432 Do not use Fdelete_overlay in delete_all_overlays
9433 to avoid redundant calls to unchain_overlay.
9434 * buffer.c (drop_overlay): New function.
9435 (delete_all_overlays, Fdelete_overlay): Use it.
9436 * minibuf.c (get_minibuffer): Fix comment.
9438 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9440 Port to OpenBSD 5.1 amd64.
9441 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9442 This is needed for OpenBSD, and should be harmless on all BSD systems.
9443 Also, include <sys/sysctl.h>, as it should be available on all
9444 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9445 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9446 use p_pid member, not kp_proc.pid.
9448 2012-07-06 Glenn Morris <rgm@gnu.org>
9450 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9452 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9454 More xmalloc and related cleanup.
9455 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9456 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
9457 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
9458 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
9459 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
9460 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
9461 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9462 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9463 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9465 Omit needless casts involving void * pointers and allocation.
9466 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9467 as the former is more robust if P's type is changed.
9468 Prefer xzalloc to xmalloc + memset 0.
9469 Simplify malloc-or-realloc to realloc.
9470 Don't worry about xmalloc returning a null pointer.
9471 Prefer xstrdup to xmalloc + strcpy.
9472 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9474 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9475 alloca of a constant.
9477 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9479 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9480 hscroll is larger than the line width. Fixes long and futile
9481 looping inside extend_face_to_end_of_line (on a TTY) producing
9482 glyphs that are not needed and thrown away.
9484 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9486 * marker.c (set_marker_restricted_both): Simplify by using

9491 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9493 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

9496 not defined (Bug#11768).
9497 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9498 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9499 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9500 followed by gtk_box_set_homogeneous (Bug#11768).
9501 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9502 (update_theme_scrollbar_width, xg_create_scroll_bar):
9503 Use gtk_scrollbar_new (Bug#11768).
9504 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9512 * xdisp.c (window_hscroll_limited): New function.
9513 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9514 coordinates when window's hscroll is set to insanely large
9517 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9519 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9580 * fileio.c (time_error_value): Check the right error number.
9581 Problem reported by Troels Nielsen in
9582 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9586 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9587 This should be fixed in a better way; see Eli Zaretskii in
9588 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9589 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9591 * fileio.c (time_error_value): Rename from special_mtime.
9592 The old name's problems were noted by Eli Zaretskii in
9593 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9595 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9596 This variable's comment says Emacs needs at least one GDB-visible
9597 symbol of type enum pvec_type, to work around GDB problems.
9598 The symbol's value doesn't matter.
9600 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9601 that causes compilation to fail on pre-C99 compilers.
9603 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9605 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9606 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9608 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9610 * buffer.c (init_buffer_once): Fix initialization of
9611 headers for buffer_defaults and buffer_local_symbols.
9612 Reported by Juanma Barranquero <lekktu@gmail.com>.
9614 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9616 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9617 * lisp.h (enum pvec_type): Use fewer bits.
9618 (PSEUDOVECTOR_SIZE_BITS): New constant.
9619 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9620 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9621 change in pvec_type.
9622 (PSEUDOVECTOR_TYPEP): New macro.
9623 (TYPED_PSEUDOVECTORP): Use it.
9624 * fns.c (internal_equal): Adapt code to extract pvectype.

9628 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9629 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9630 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9631 abusing vector->header.next.nbytes.
9632 (live_vector_p): Use PVEC_TYPE.
9633 (mark_object): Adapt code to extract pvectype. Use switch.
9635 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9637 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9638 Tighten new eassert a bit.
9640 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9642 Fix compilation with --enable-gcc-warnings and -O1
9644 * doprnt.c (doprnt): Change type of tem to int, initialize
9645 to avoid compiler warning. Add eassert.
9646 * search.c (simple_search): Initialize match_byte to avoid
9647 compiler warning. Add eassert.
9649 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9651 Avoid weird behavior with large horizontal scrolls.
9652 Without this change, for example, large hscroll values would
9653 mess up Emacs's display on Fedora 15 x86, presumably due to
9654 overflows in int calculations in the display code.
9655 Also, if buffers had long lines, Emacs would freeze.
9656 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9657 (set_window_hscroll): New function, containing the old guts of
9658 Fset_window_hscroll. Return the clipped value.
9659 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9660 This avoids the need to check against PTRDIFF_MAX.
9662 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9664 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9666 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9668 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9670 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9671 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9672 since GCC 4.4.6 issues a bogus warning for them.
9674 Fix bugs in file timestamp newness comparisons.
9675 * fileio.c (Ffile_newer_than_file_p):
9676 * lread.c (Fload): Use full timestamp resolution of files,
9677 not just the 1-second resolution, so that files that are only
9678 slightly newer still count as newer.
9679 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9680 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9682 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9684 * fileio.c: Improve handling of file time marker. (Bug#11852)
9685 (special_mtime): New function.
9686 (Finsert_file_contents, Fverify_visited_file_modtime):
9687 Use it to set special mtime values consistently.
9689 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9691 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9692 marker for non-existing file. (Bug#11852)
9694 2012-07-03 Glenn Morris <rgm@gnu.org>
9696 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9697 and did not make it into globals.h).
9699 2012-07-03 Tom Tromey <tromey@redhat.com>
9701 * window.c (Fset_window_margins, Fset_window_fringes)

9737 2012-07-03 Glenn Morris <rgm@gnu.org>
9739 * lisp.h (Frandom): Make it visible to C.
9740 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9741 buffer for invisible buffers. (Bug#1229)

9745 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9746 values which aren't power of 2.
9747 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9748 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9751 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9753 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9755 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9757 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9759 * alloc.c (allocate_vector_block): Remove redundant
9760 calls to mallopt if DOUG_LEA_MALLOC is defined.
9761 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9762 avoid calls to mallopt if zero_vector is returned.
9764 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9766 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9767 is enabled, avoid dereferencing NULL current_sblock if
9770 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9772 Cleanup basic buffer management.
9773 * buffer.h (struct buffer): Change layout to use generic vector
9774 marking code. Fix some comments. Change type of 'clip_changed'
9775 to bitfield. Remove unused #ifndef old.
9776 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9777 (GET_OVERLAYS_AT): Fix indentation.
9778 (for_each_per_buffer_object_at): New macro.

9782 * alloc.c (allocate_buffer): Adjust to match new layout of
9783 struct buffer. Fix comment.
9784 (mark_overlay): New function.

9787 (mark_object): Use it. Adjust marking of misc objects
9788 and related comments.
9790 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9792 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9793 wrapper that is not needed because the wrapped code is a no-op (zero
9794 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9795 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9797 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9799 * alloc.c (mark_buffer): Simplify. Remove prototype.
9800 (mark_object): Add comment. Reorganize marking of vector-like
9801 objects. Use CHECK_LIVE for all vector-like objects except buffers
9802 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9803 Avoid redundant calls to mark_vectorlike for bool vectors.
9805 2012-06-30 Glenn Morris <rgm@gnu.org>
9807 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9809 * epaths.in (PATH_SITELOADSEARCH): New.
9810 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9811 This is rather than relying on --enable-locallisppath elements
9812 having "site-lisp" in their names. (Bug#10208#25, 11658)
9814 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9816 * w32proc.c (sys_select): Accept and ignore one more argument.
9818 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9820 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9821 (pselect) [!MS_DOS]: Redirect to sys_select.
9823 * sysdep.c: Don't include dos.h and dosfns.h.
9825 * process.c (sys_select):
9826 * msdos.c (sys_select): Accept one more argument and ignore it.
9828 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9829 adapt data types and code to that.
9832 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9833 which clashes with the gnulib function of the same name.
9835 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9837 * font.c (font_style_to_value, font_style_symbolic)
9838 (font_prop_validate_style): Add type checks for values in
9841 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9843 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9846 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9848 * xdisp.c (try_window_id): Undo last change.
9850 * w32.c (getwd): Adjust commentary about startup_dir.
9851 (init_environment): Always call sys_access, even in non-MSVC
9852 builds. Don't chdir to the directory of the Emacs executable.
9853 This undoes code from 1997 which was justified by the need to
9854 "avoid conflicts when removing and renaming directories". But its
9855 downside was that every relative file name was being interpreted
9856 relative to the directory of the Emacs executable, which can never
9857 be TRT. In particular, it broke sys_access when called with
9858 relative file names.
9859 (sys_access): Map GetLastError to errno.
9861 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9863 * window.h (struct window): Change type of 'fringes_outside_margins'

9867 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9870 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9872 * gnutls.c (emacs_gnutls_handshake):
9873 Add QUIT to make the loop interruptible.
9875 2012-06-29 Glenn Morris <rgm@gnu.org>
9877 * charset.c (init_charset): Make lack of etc/charsets fatal.
9879 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9881 * editfns.c (region_limit): Fix type mismatch.
9883 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9885 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9886 undefined. Convert from xassert to eassert.
9887 * nsmenu.m: Convert from xassert to eassert.
9888 * nsterm.m: Likewise.
9890 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9892 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9894 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9896 Avoid integer overflow on scroll-left and scroll-right.
9897 * window.c (HSCROLL_MAX): New macro.
9898 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9899 overflow when requested scroll falls outside ptrdiff_t range.
9901 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9903 * window.h (struct window): Change type of 'hscroll',
9904 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9905 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9906 Adjust users accordingly.
9907 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9908 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9909 from EMACS_INT to ptrdiff_t.
9910 (make_window): Omit redundant initialization.
9912 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9914 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9916 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9918 * window.h (struct window): Change type of 'use_time' and
9919 'sequence_number' from Lisp_Object to int.

9927 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9928 enabled with --enable-checking=[all,glyphs] configure option.
9929 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9930 adjust comments accordingly.

9985 * alloc.c (allocate_string): Omit intervals initialization.
9986 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9987 as in make_pure_string and make_pure_c_string.
9989 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

10043 * alloc.c: Remove build_string.
10044 * lisp.h: Define build_string as static inline. This provides
10045 a better opportunity to optimize away calls to strlen when the
10046 function is called with compile-time constant argument.
10047 * image.c (imagemagick_error): Convert to build_string.
10048 * w32proc.c (sys_spawnve): Likewise.

10051 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10053 Use sprintf return value instead of invoking strlen on result.
10054 In the old days this wasn't portable, since some sprintf
10055 implementations returned char *. But they died out years ago and
10056 Emacs already assumes sprintf returns int.
10057 Similarly for float_to_string.
10058 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10066 Use sprintf or float_to_string result to avoid need to call strlen.
10067 * data.c (Fnumber_to_string):
10068 Use make_unibyte_string, since the string must be ASCII.
10069 * lisp.h, print.c (float_to_string): Now returns int length.
10070 * term.c (produce_glyphless_glyph):
10071 Use sprintf result rather than recomputing it.
10073 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10074 * Makefile.in (ALL_CFLAGS):
10075 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10100 sprintf already null-terminates its output.
10102 * xfns.c (x_window): Remove redundant cast.
10104 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10106 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10107 `const char *' to `char *' to avoid compiler warning.
10109 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10111 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10112 instead of truncating it to 63 (admittedly a generous limit).
10114 * process.c: Fix spelling and caps in comments.

10167 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10169 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

10171 * dispnew.c (Fsleep_for, sit_for):
10172 * keyboard.c (kbd_buffer_get_event):
10173 * process.c (Faccept_process_output):
10174 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10175 This improves on the previous patch, which introduced a bug
10176 when time_t is unsigned and as wide as intmax_t.
10177 See <http://bugs.gnu.org/9000#51>.
10179 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10205 last argument of make_unibyte_string.
10207 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10208 language ID in the event parameters.
10210 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10211 event.code, not the obscure "character set ID".
10213 2012-06-23 Chong Yidong <cyd@gnu.org>
10215 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10242 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10244 Support higher-resolution time stamps (Bug#9000).
10245 The time stamps are only nanosecond-resolution at the C level,
10246 since that's the best that any real-world system supports now.
10247 But they are picosecond-resolution at the Lisp level, as that's
10248 easy, and leaves room for future OS improvements.
10250 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10253 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10254 Don't get current time unless it's needed.
10256 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10257 now provides it if it's absent.
10258 (start_atimer): Port to higher-res time stamps.
10259 Check for time stamp overflow. Don't get current time more
10260 often than is needed.
10262 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10263 Include systime.h, not time.h.
10264 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10266 * dired.c: Include stat-time.h.
10267 (Ffile-attributes): File times now have higher resolution.
10269 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10270 (struct image): Timestamp now has higher resolution.
10272 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10273 has at least microseconds now. All uses removed.
10274 (update_frame, update_single_window, update_window, update_frame_1)
10275 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10276 (duration_to_sec_usec): Remove; no longer needed.
10278 * editfns.c (time_overflow): Now extern.
10279 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10280 (float-time, Fformat_time_string, Fcurrent_time_string)

10283 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10284 (decode_time_components, lisp_seconds_argument): New functions.
10285 (make_time): Now static.
10286 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10287 Report an error if the time is invalid, rather than having the caller
10290 * fileio.c: Include <stat-time.h>
10291 (Fcopy_file): Copy higher-resolution time stamps.
10292 Prefer to set the time stamp via a file descriptor if that works.
10293 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10294 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10295 (Fvisited_file_modtime, Fset_visited_file_modtime):
10296 Support higher-resolution time stamps.
10298 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10300 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10302 * image.c (prepare_image_for_display, clear_image_cache)
10303 (lookup_image): Port to higer-resolution time stamps.
10305 * keyboard.c (start_polling, bind_polling_period):
10306 Check for time stamp overflow.
10307 (read_char, kbd_buffer_get_event, timer_start_idle)
10308 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10309 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10310 Port to higher-resolution time stamps. Do not assume time_t is signed.
10311 (decode_timer): New function. Timers are now vectors of length 9,
10312 not 8, to accommodate the picosecond component.
10313 (timer_check_2): Use it.
10315 * nsterm.m (select_timeout, timeval_subtract): Remove.
10316 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10317 as they're a bit more accurate and handle overflow better.
10318 (ns_select): Change prototype to be compatible with pselect.
10319 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10320 * nsterm.h (ns_select): Adjust prototype.
10322 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10323 us-resolution time stamps.
10324 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10326 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10328 * lisp.h (time_overflow): New decl.
10329 (wait_reading_process_output): First arg is now intmax_t, not int,
10330 to accommodate larger waits.
10332 * process.h (struct Lisp_Process.read_output_delay):
10333 Now counts nanoseconds, not microseconds.
10334 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10336 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10337 (wait_reading_process_output):
10338 Port to ns-resolution time stamps.
10339 (Faccept_process_output, wait_reading_process_output):
10340 Check for time stamp overflow. Do not assume time_t is signed.
10341 (select_wrapper): Remove; we now use pselect.
10342 (Fprocess_attributes): Now generates ns-resolution time stamps.
10344 * sysdep.c: Include utimens.h. Don't include utime.h
10345 or worry about struct utimbuf; gnulib does that for us now.
10346 (gettimeofday): Remove; gnulib provides a substitute.
10347 (make_timeval): New function.
10348 (set_file_times): Now sets ns-resolution time stamps.
10349 New arg FD; all uses changed.
10350 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10351 (system_process_attributes):
10352 Now returns ns-resolution time stamp. All uses changed.
10353 Check for time stamp overflow.
10355 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10356 provides a substitute now.
10358 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10359 since it guarantees struct timespec.
10360 (EMACS_TIME): Now struct timespec, so that we can support
10361 ns-resolution time stamps.
10362 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10363 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10364 (EMACS_USECS): Remove.
10365 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10366 so multiply the arg by 1000 before storing it.
10367 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10369 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10370 Port to ns-resolution time stamps.
10371 (EMACS_TIME_NEG_P): Remove; replaced by....
10372 (EMACS_TIME_SIGN): New macro.
10373 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10374 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10375 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10376 (make_timeval, make_lisp_time, decode_time_components): New decls.
10377 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10378 that it mishandled time_t overflow. You can't compare by subtracting!
10379 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10380 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10382 * term.c: Include <sys/time.h>.
10383 (timeval_to_Time): New function, for proper overflow wraparound.
10384 (term_mouse_position, term_mouse_click): Use it.
10386 * undo.c (record_first_change): Support higher-resolution time stamps
10387 in the undo buffer.
10388 (Fprimitive_undo): Use them when restoring time stamps.
10390 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10391 (w32_get_internal_run_time):
10392 Port to higher-resolution Emacs time stamps.
10393 (ltime): Now accepts single 64-bit integer, as that's more convenient
10396 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10398 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10399 for compatibility with pselect. Support ns-resolution time stamps.
10401 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10403 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10404 Check for time stamp overflow, and support ns-resolution time stamps.
10406 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10407 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10408 (timeval_subtract): Remove; no longer needed.
10409 (XTflash, XTring_bell, x_wait_for_event):
10410 Port to ns-resolution time stamps. Don't assume time_t is signed.
10412 2012-06-22 Chong Yidong <cyd@gnu.org>
10414 * xdisp.c (x_consider_frame_title): Revert last change.
10416 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10418 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10419 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10420 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10421 staticidx goes up to 1597 out of 1600 = 0x640.)

10874 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
10875 (note_mode_line_or_margin_highlight): If there is no help echo,
10876 use mode-line-default-help-echo. Handle the case where the mouse
10877 position is past the end of the mode line string.
10879 * buffer.c (buffer_local_value_1): New function, split from
10880 Fbuffer_local_value; can return Qunbound.
10881 (Fbuffer_local_value): Use it.
10882 (Vmode_line_format): Docstring tweaks.
10884 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10886 * sysdep.c (system_process_attributes): Improve comment.
10888 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
10890 * keyboard.c: Export real-this-command to Elisp.
10891 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
10892 and DEFVAR it. Update all users.
10894 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10896 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10898 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10899 Convert pctcpu and pctmem to Lisp float properly.
10900 Let the compiler fold better, as 100.0/0x8000 is exact.
10902 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10904 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10907 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
10909 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
10911 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10913 For a 'struct window', replace some Lisp_Object fields to
10914 bitfields where appropriate, remove unused fields.
10915 * window.h (struct window): Remove unused 'last_mark_x' and
10916 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10917 change its type from Lisp_Object to bitfield.
10918 Change type of 'force_start', 'optional_new_start',
10919 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10920 fields from Lisp_Object to bitfield. Adjust users accordingly.
10922 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10924 Pacify gcc -Wdouble-precision when using Xaw.
10925 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10926 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10927 Use 'float' consistently, rather than 'float' in most places
10928 and 'double' in a couple of places.
10930 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10932 * xdisp.c (handle_stop): Detect whether we have overlay strings
10933 loaded by testing it->current.overlay_string_index to be
10934 non-negative, instead of checking whether n_overlay_strings is
10935 positive. (Bug#11587)
10937 2012-05-31 Chong Yidong <cyd@gnu.org>
10939 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10941 * doc.c (Fsubstitute_command_keys): Doc fix.
10943 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10945 * search.c (search_buffer): Remove calls to
10946 r_alloc_inhibit_buffer_relocation, as it is now called by
10947 maybe_unify_char, which was the cause of relocation of buffer text
10950 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10952 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10953 for the duration of call to load_charset, to avoid problems with
10954 callers of maybe_unify_char that access buffer text through C
10957 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10958 decrement the inhibition flag, instead of just setting or
10961 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10963 Remove obsolete '#define static' cruft.
10964 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10965 This #undef was "temporary" in 2000; it is no longer needed
10966 now that '#define static' has gone away.
10967 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10968 (gray_bitmap_bits): Remove; no longer needed.
10969 All uses replaced with definiens.
10970 * xterm.c: Include "bitmaps/gray.xbm".
10972 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10974 Clean up __executable_start, monstartup when --enable-profiling.
10975 The following changes affect the code only when profiling.
10976 * dispnew.c (__executable_start): Rename from safe_bcopy.
10977 Define only on platforms that need it.
10978 * emacs.c: Include <sys/gmon.h> when profiling.
10979 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10980 (__executable_start): Remove decl, since lisp.h does it now.
10981 (safe_bcopy): Remove decl; no longer has that name.
10982 (main): Coalesce #if into single bit of code, for simplicity.
10983 Cast pointers to uintptr_t, since standard libraries want integers
10985 * lisp.h (__executable_start): New decl.
10987 2012-05-31 Glenn Morris <rgm@gnu.org>
10989 * image.c (Fimagemagick_types): Doc fix.
10991 2012-05-30 Jim Meyering <meyering@redhat.com>
10993 * callproc.c (Fcall_process_region): Include directory component
10994 in mkstemp error message (Bug#11586).
10996 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10998 * alloc.c, lisp.h (make_pure_vector): Now static.
11000 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
11002 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
11003 Move to byte-run.el.
11004 (Fautoload): Do the hash-doc more carefully.
11005 * data.c (Fdefalias): Purify definition, except for keymaps.
11006 (Qdefun): Move from eval.c.
11007 * lisp.h (Qdefun): Remove.
11008 * lread.c (read1): Tiny simplification.
11010 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11012 Do not create empty overlays with the evaporate property (Bug#9642).
11013 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11014 Bug#9642, but explicitly check that the buffer the overlay would
11015 be moved to is live and rearrange lines to make sure that errors
11016 will not put the overlay in an inconsistent state.
11017 (Fdelete_overlay): Cosmetics.
11019 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11021 * w32term.c (my_bring_window_to_top): New function.
11022 (x_raise_frame): Use handle returned by DeferWindowPos, which
11023 could be different from the original one.
11024 Call my_bring_window_to_top instead of my_set_foreground_window.
11027 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11028 by calling BringWindowToTop.
11030 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

11033 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11035 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11036 This avoids undefined behavior that might cause the eassert
11037 to not catch an out-of-range value.
11039 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11041 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11042 Update dependencies.
11044 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11046 * bidi.c (bidi_mirror_char): Fix last change.
11048 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11050 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11051 when referring to sectname field in printf format.
11053 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11055 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11056 Only r_alloc_inhibit_buffer_relocation needed to be added;
11057 the others were already declared.
11059 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11060 before checking whether it's out of range. Put the check inside
11062 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11064 2012-05-27 Ken Brown <kbrown@cornell.edu>
11066 * callproc.c (Fcall_process): Restore a line that was accidentally
11067 commented out in the 2011-02-13 change (bug#11547).
11069 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11071 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11072 defined on ralloc.c.
11074 * buffer.c [REL_ALLOC]: Remove prototypes of
11075 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11076 they are now on lisp.h.
11078 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11080 * search.c (search_buffer): Use it to inhibit relocation of buffer
11081 text while re_search_2 is doing its job, because re_search_2 is
11082 passed C pointers to buffer text. (Bug#11519)
11084 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11085 Update value to 24.
11087 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11088 state after an additional call to move_it_in_display_line_to, keep
11089 the values of it->max_ascent and it->max_descent found for the
11091 (pos_visible_p): Revert the comparison against bottom_y to what it
11092 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11095 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11097 Fix coding-related core dumps with gcc -ftrapv.
11098 The code was computing A - B, where A and B are pointers, and B is
11099 random garbage. This can lead to core dumps on platforms that
11100 have special pointer registers, and it also leads to core dumps on
11101 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11102 A - B only when B is initialized properly.
11103 * coding.c (coding_set_source, coding_set_destination): Return void.
11104 (coding_change_source, coding_change_destinations): New functions,
11105 with the old behaviors of coding_set_source and coding_set_destination.
11106 All callers that need an offset changed to use these new functions.
11108 2012-05-26 Glenn Morris <rgm@gnu.org>
11110 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11112 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11114 Extend mouse support on W32 text-mode console.
11115 * xdisp.c (draw_row_with_mouse_face):
11116 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11118 * w32console.c: Include window.h.
11119 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11121 (initialize_w32_display): Initialize mouse-highlight data.
11123 * w32inevt.c: Include termchar.h and window.h.
11124 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11125 moves, call note_mouse_highlight. If help_echo changed, call
11126 gen_help_event to produce help-echo message in the echo area.
11127 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11130 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11132 * lread.c (read1): Simplify slightly to avoid an overflow warning
11133 with GCC 4.7.0 on x86-64.
11135 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11137 * bidi.c (bidi_mirror_char): Revert last change: an int is
11138 definitely wide enough here.
11140 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11142 Fix integer width and related bugs (Bug#9874).
11143 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11144 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11145 (string_bytes, check_sblock, allocate_string_data):
11146 (compact_small_strings, Fmake_bool_vector, make_string)
11147 (make_unibyte_string, make_multibyte_string)
11148 (make_string_from_bytes, make_specified_string)
11149 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11150 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11152 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11153 (allocate_pseudovector):
11154 Use int, not EMACS_INT, where int is wide enough.
11155 (inhibit_garbage_collection, Fgarbage_collect):
11156 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11157 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11158 int might not be wide enough.
11159 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11160 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11161 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11162 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11163 (bidi_level_of_next_char, bidi_move_to_visually_next):
11164 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11165 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11166 (Fkill_buffer, Fset_buffer_major_mode)
11167 (advance_to_char_boundary, Fbuffer_swap_text)
11168 (Fset_buffer_multibyte, overlays_at, overlays_in)
11169 (overlay_touches_p, struct sortvec, record_overlay_string)
11170 (overlay_strings, recenter_overlay_lists)
11171 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11172 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11173 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11174 (Foverlay_recenter, last_overlay_modification_hooks_used)
11175 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11176 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11177 (validate_region): Omit unnecessary test for b <= e,
11178 since that's guaranteed by the previous test.
11179 (adjust_overlays_for_delete): Avoid pos + length overflow.
11180 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11181 (report_overlay_modification):
11182 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11183 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11184 Omit pointer cast, which isn't needed anyway, and doesn't work
11185 after the EMACS_INT -> ptrdiff_t change.
11186 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11187 * buffer.h: Adjust decls to match defn changes elsewhere.
11188 (struct buffer_text, struct buffer):
11189 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11190 Use EMACS_INT, not int, where int might not be wide enough.
11191 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11192 not int, to avoid needless 32-bit limit on 64-bit hosts.
11193 (exec_byte_code): Use tighter memory-full test, one that checks
11194 for alloca overflow. Don't compute the address of the object just
11195 before an array, as that's not portable. Use EMACS_INT, not
11196 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11197 * callint.c (Fcall_interactively):
11198 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11199 * callproc.c (call_process_kill, Fcall_process):
11200 Don't assume pid_t fits into an Emacs fixnum.
11201 (call_process_cleanup, Fcall_process, child_setup):
11202 Don't assume pid_t fits into int.
11203 (call_process_cleanup, Fcall_process, delete_temp_file)
11204 (Fcall_process_region):
11205 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11206 (Fcall_process): Simplify handling of volatile integers.
11207 Use int, not EMACS_INT, where int will do.
11208 * casefiddle.c (casify_object, casify_region, operate_on_word)
11209 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11210 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11211 (casify_object): Avoid integer overflow when overallocating buffer.
11212 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11213 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11214 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11215 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11216 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11217 integers are now checked earlier. All uses replaced with XINT.
11219 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11220 For CCL_MapSingle, check that content and value are in int range.
11221 (ccl_driver, Fregister_code_conversion_map):
11222 Check that Vcode_version_map_vector is a vector.
11223 (resolve_symbol_ccl_program): Check that vector header is in range.
11224 Always copy the vector, so that we can check its contents reliably
11225 now rather than having to recheck each instruction as it's being
11226 executed. Check that vector words fit in 'int'.
11227 (ccl_get_compiled_code, Fregister_ccl_program)
11228 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11229 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11230 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11231 contents are in range.
11232 (Fccl_execute_on_string): Check that status is in range.
11233 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11234 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11235 Accept and return EMACS_INT, not int, because callers can pass values
11236 out of 'int' range.
11237 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11238 (multibyte_chars_in_text, parse_str_as_multibyte)
11239 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11240 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11241 (string_escape_byte8, Fget_byte):
11242 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11243 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11244 avoid mishandling large integers.
11245 * character.h: Adjust decls to match defn changes elsewhere.
11246 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11247 (Ffind_charset_region):
11248 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11249 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11250 (load_charset_map_from_vector, Fdefine_charset_internal):
11251 Don't assume fixnum fits in int.
11252 (load_charset_map_from_vector, Fmap_charset_chars):
11253 Remove now-unnecessary CHECK_NATNUMs.
11254 (Fdefine_charset_internal): Check ranges here, more carefully.
11255 Don't rely on undefined behavior with signed left shift overflow.
11256 Don't assume unsigned int fits into fixnum, or that fixnum fits
11257 into unsigned int. Don't require max_code to be a valid fixnum;
11258 that's not true for gb10830 4-byte on a 32-bit host. Allow
11259 invalid_code to be a cons, for the same reason. Require code_offset
11260 to be a character. Avoid int overflow if max_char is close
11262 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11263 this is intended anyway and avoids some undefined behavior.
11264 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11265 INDEX_TO_CODE_POINT, as that's what it expects.
11266 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11267 * charset.h (DECODE_CHAR): Return int, not unsigned;
11268 this is what was intended anyway, and it avoids undefined behavior.
11269 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11270 integer-overflow issues.
11271 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11272 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11273 where the argument is EMACS_INT, and this behavior is not intended.
11274 * chartab.c (Fmake_char_table, Fset_char_table_range)
11275 (uniprop_get_decoder, uniprop_get_encoder):
11276 Don't assume fixnum fits in int.
11277 * cmds.c (move_point): New function, that does the gist of
11278 Fforward_char and Fbackward_char, but does so while checking
11279 for integer overflow more accurately.
11280 (Fforward_char, Fbackward_char): Use it.
11281 (Fforward_line, Fend_of_line, internal_self_insert)
11282 (internal_self_insert):
11283 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11961 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11963 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11964 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11966 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11969 This directory predates autoconf and is no longer needed nowadays.
11970 Move its few remaining bits of functionality to where they're needed.
11971 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11972 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11973 * m/template.h: Remove.
11974 * Makefile.in (M_FILE): Remove. All uses removed.
11975 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11976 * lisp.h (USE_LSB_TAG):
11977 * mem-limits.h (EXCEEDS_LISP_PTR):
11978 Use VAL_MAX, not VALBITS, in #if.
11979 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11980 (EMACS_UINT): Define unconditionally now.
11981 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11982 (BITS_PER_EMACS_INT): New constants, replacing
11983 what used to be in config.h, but not useful in #if.
11984 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11985 define them any more.
11986 (VAL_MAX): New macro.
11988 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11989 BITS_PER_EMACS_INT, in #if.
11990 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11991 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11992 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11993 * s/ms-w32.h (DATA_START):
11994 Move here from removed file m/intel386.h.
11995 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11996 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11998 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12000 Assume C89 or later.
12001 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12002 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12004 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12005 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12006 * textprop.c, tparam.c (NULL): Remove.
12007 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12008 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12009 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12010 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12011 * xterm.c (input_signal_count): Assume volatile works.
12013 2012-05-21 Ken Brown <kbrown@cornell.edu>
12015 * xgselect.c (xg_select): Fix first argument in call to 'select'
12018 2012-05-20 Ken Brown <kbrown@cornell.edu>
12020 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12021 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12023 2012-05-19 Ken Brown <kbrown@cornell.edu>
12025 * xfns.c (x_in_use): Remove `static' qualifier.
12026 * xterm.h (x_in_use): Declare.
12027 * xgselect.c: Include xterm.h.
12028 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12029 and `display_arg' (bug#9754).
12031 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12033 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12035 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12036 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12038 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12040 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12042 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12043 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12045 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12046 reference to image_cache->refcount.
12047 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12049 2012-05-17 Juri Linkov <juri@jurta.org>
12051 * search.c (Fword_search_regexp, Fword_search_backward)
12052 (Fword_search_forward, Fword_search_backward_lax)
12053 (Fword_search_forward_lax): Move functions to isearch.el
12054 (bug#10145, bug#11381).
12056 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12058 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12060 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12062 * lread.c (init_obarray): Declare Qt and Qnil as special.
12064 2012-05-14 Glenn Morris <rgm@gnu.org>
12066 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12067 Put "libexec" before "bin", for the sake of init_callproc_1.
12069 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12071 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12073 * unexaix.c: Port to more-recent AIX compilers.
12074 (report_error, report_error_1, make_hdr, copy_sym)
12075 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12076 Make arguments const char *, not char *, to avoid violations of C
12077 standard and to fix some AIX warnings reported by Gilles Pion.
12079 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12081 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12082 already have overlays loaded.
12083 (handle_single_display_spec): Before returning without displaying
12084 fringe bitmap, synchronize the bidi iterator with the main display
12085 iterator, by calling iterate_out_of_display_property.
12086 (iterate_out_of_display_property): Detect buffer iteration by
12087 testing that it->string is a Lisp string.
12088 (get_next_display_element): When the current object is exhausted,
12089 and there's something on it->stack, call set_iterator_to_next to
12090 proceed with what's on the stack, instead of returning zero.
12091 (set_iterator_to_next): If called at the end of a Lisp string,
12092 proceed to consider_string_end without incrementing string
12093 position. Don't increment display vector index past the end of
12094 the display vector. (Bug#11417)
12095 (pos_visible_p): Don't report a position visible when move_it_to
12096 stopped at the last line of window, which happens to be scanned
12097 backwards by the bidi iteration. (Bug#11464)
12099 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12101 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12102 and right-margin display specs even if the spec is invalid or we
12103 are on a TTY, and thus unable to display on the fringes.
12104 That's because the text with the property will not be displayed anyway,
12105 so we need to signal to the caller that this is a "replacing"
12106 display spec. This fixes display when the spec is invalid or we
12109 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12111 * unexaix.c (make_hdr): Fix typo in prototype.
12112 This bug broke the build on AIX. Problem reported by Gilles Pion.
12114 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12116 * keyboard.c (kbd_buffer_get_event): Read special events also in
12117 batch mode. (Bug#11415)
12119 2012-05-12 Glenn Morris <rgm@gnu.org>
12121 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12123 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12125 * lisp.mk (lisp): Add newcomment.elc.
12127 2012-05-12 Glenn Morris <rgm@gnu.org>
12129 * Makefile.in (MKDIR_P): New, set by configure.
12130 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12132 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12134 Remove unused function hourglass_started.
12135 * dispextern.h (hourglass_started):
12136 * w32fns.c (hourglass_started):
12137 * xdisp.c (hourglass_started): Remove.
12139 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12141 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12142 Update dependencies.
12144 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12146 * xgselect.c (xg_select): Put maxfds+1 into a var.
12147 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12149 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12151 2012-05-10 Dave Abrahams <dave@boostpro.com>
12153 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12154 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12156 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12158 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12159 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12160 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12161 Initialize xd_registered_buses.
12163 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12165 Untag more efficiently if USE_LSB_TAG.
12166 This is based on a proposal by YAMAMOTO Mitsuharu in
12167 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12168 For an admittedly artificial (nth 8000 longlist) benchmark on
12169 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12170 Emacs's overall text size by 1%.
12171 * lisp.h (XUNTAG): New macro.
12172 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12173 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12174 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12175 * eval.c (Fautoload):
12176 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12177 * frame.h (XFRAME): Use XUNTAG.
12179 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12180 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12181 Remove unportable assumptions about print widths of types like
12183 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12184 intptr_t when converting between pointer and integer, to avoid GCC
12185 warnings about wrong width.
12187 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12189 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12190 stack for each reader_thread, instead of defaulting to 8MB
12191 determined by the linker. This avoids failures in creating
12192 subprocesses on Windows 7, see the discussion in this thread:
12193 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12195 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12197 Fix up display of the *Minibuf-0* buffer in the mini window.
12198 * keyboard.c (read_char): Don't clear the echo area if there's no
12200 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12201 contents of *Minibuf-0*) if there's no message displayed in its stead.
12203 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12205 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12208 2012-05-06 Chong Yidong <cyd@gnu.org>
12210 * lisp.mk (lisp): Update.
12212 2012-05-05 Jim Meyering <meyering@redhat.com>
12214 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12216 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12218 * data.c (PUT_ERROR): New macro.
12219 (syms_of_data): Use it. Add new error type `user-error'.
12220 * undo.c (user_error): New function.
12221 (Fprimitive_undo): Use it.
12222 * print.c (print_error_message): Adjust print style for `user-error'.
12223 * keyboard.c (user_error): New function.
12224 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12226 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12228 Do not limit current-time-string to years 1000..9999.
12229 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12230 (Fcurrent_time_string): Support any year that is supported by the
12231 underlying localtime representation. Don't use asctime, as it
12232 has undefined behavior for years outside the range -999..9999.
12234 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12236 Fix race conditions involving setenv, gmtime, localtime, asctime.
12237 Without this fix, interrupts could mess up code that uses these
12238 nonreentrant functions, since setting TZ invalidates existing
12239 tm_zone or tzname values, and since most of these functions return
12240 pointers to static storage.
12241 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12242 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12243 Grow the critical sections to include not just invoking
12244 localtime/gmtime, but also accessing these functions' results
12245 including their tm_zone values if any, and any related TZ setting.
12246 (format_time_string): Last arg is now struct tm *, not struct tm **,
12247 so that the struct tm is saved in the critical section.
12248 All callers changed. Simplify allocation of initial buffer, partly
12249 motivated by the fact that memory allocation needs to be outside
12250 the critical section.
12252 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12254 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12255 with RESET_INTERVAL.
12257 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12258 Remove duplicated buffer name initialization.
12260 2012-05-02 Jim Meyering <jim@meyering.net>
12262 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12264 * xfns.c (x_window): Use xstrdup (Bug#11375).
12266 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12268 * xdisp.c (pos_visible_p): If already at a newline from the
12269 display string before the 'while' loop, don't walk back the glyphs
12270 from it3.glyph_row. Solves assertion violation when the display
12271 string begins with a newline (egg.el). (Bug#11367)
12273 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12275 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12278 2012-05-01 Glenn Morris <rgm@gnu.org>
12280 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12281 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12282 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12283 All were removed before 23.1.
12285 * dispnew.c: Remove HAVE_LIBNCURSES test;
12286 it is always true on relevant platforms.
12288 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12289 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12291 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12293 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12295 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12296 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12299 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12301 Do not avoid creating empty evaporating overlays (Bug#9642).
12302 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12303 That is, do not delete an evaporating overlay if it becomes
12304 empty after its bounds are adjusted to fit within its buffer.
12305 This fix caused other problems, and I'm reverting it until we get
12306 to the bottom of them.
12308 2012-04-27 Chong Yidong <cyd@gnu.org>
12310 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12312 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12314 * xdisp.c (pos_visible_p): If the window start position is beyond
12315 ZV, start the display from buffer beginning. Prevents assertion
12316 violation in init_iterator when the minibuffer window is scrolled
12317 via the scroll bar.
12319 * window.c (window_scroll_pixel_based): Likewise.
12321 2012-04-27 Chong Yidong <cyd@gnu.org>
12323 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12325 2012-04-27 Glenn Morris <rgm@gnu.org>
12327 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12328 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12330 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12332 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12333 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12335 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12337 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12338 display element, check also the underlying string or buffer
12339 character. (Bug#11341)
12341 * w32menu.c: Include w32heap.h.
12342 (add_menu_item): If the call to AppendMenuW (via
12343 unicode_append_menu) fails, disable Unicode menus only if we are
12344 running on Windows 9X/Me.
12346 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12348 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12349 (xgetint): Add missing shift for LSB tags.
12351 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12353 * keyboard.c (read_char): Don't wipe echo area for select window
12354 events: These might get delayed via `mouse-autoselect-window'
12357 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12359 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12360 manipulation of :loaded-from data.
12362 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12364 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12365 now a cons (bug#11311).
12367 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12369 Do not create empty overlays with the evaporate property (Bug#9642).
12370 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12371 if it becomes empty after its bounds are adjusted to fit within
12372 its buffer. Without this fix, in a nonempty buffer (let ((o
12373 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12374 yields an empty overlay that has the evaporate property, which is
12375 not supposed to happen.
12377 Fix minor GTK3 problems found by static checking.
12378 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12379 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12380 (struct _EmacsFixedClass, emacs_fixed_get_type):
12381 Move decls here from emacsgtkfixed.h, since they needn't be public.
12382 (emacs_fixed_get_type): Now static.
12383 (emacs_fixed_class_init): Omit unused local.
12384 (emacs_fixed_child_type): Remove; unused.
12385 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12386 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12387 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12388 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12389 (EMACS_FIXED_GET_CLASS): Remove; unused.
12390 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12392 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12393 Problem reported by Juanma Barranquero for Windows -Wunused-function.

12490 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12492 * sysdep.c [__FreeBSD__]: Minor cleanups.
12493 (list_system_processes, system_process_attributes) [__FreeBSD__]:

12579 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12580 (NEED_MEM_INSERT): New macro.
12581 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12582 Remove one incorrect comment and fix another.

12618 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12619 * s/netbsd.h, s/sol2-6.h:
12620 Remove definition of GC_MARK_STACK, since the default now works.
12621 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12649 2012-04-11 Daniel Colascione <dancol@dancol.org>
12651 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12652 against is gone. It's better to use vfork now so that when Cygwin
12653 gains a new, working vfork, we use it automatically (bug#10398).
12655 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12710 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12712 * xdisp.c (set_cursor_from_row): If the display string appears in
12713 the buffer at position that is closer to point than the position
12714 after the display string, display the cursor on the first glyph of
12715 the display string. Fixes cursor display when a 'display' text
12716 property immediately follows invisible text. (Bug#11094)
12718 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12720 composite.c: use 'double' consistently
12721 * composite.c (get_composition_id): Use 'double' consistently
12722 instead of converting 'float' to 'double' and vice versa; this is
12723 easier to understand and avoids a GCC warning.
12725 2012-04-09 Glenn Morris <rgm@gnu.org>

12777 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12779 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

12789 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12791 * indent.c (Fvertical_motion): If there is a display string at
12792 point, use it.vpos to compute how many lines to backtrack after
12793 move_it_to point. (Bug#11133)
12795 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12797 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12798 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12799 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12800 macros related to unification of CJK characters. For the details,
12801 see the discussion following the message here:
12802 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

12818 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12820 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12821 position we get to after a call to move_it_to fails the
12822 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12823 only if we wind up in a string from display property. (Bug#11063)
12825 * window.c (Fdelete_other_windows_internal): Invalidate the row
12826 and column information about mouse highlight, so that redisplay
12827 restores it after reallocating the glyph matrices. (Bug#7464)
12829 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12830 string comes from a `display' text property, use the buffer
12831 position of that property as if we actually saw that position in
12833 (move_it_by_lines): Remove the assertion that
12834 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12835 violated when there's a before-string at the beginning of a line.
12838 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12840 * xdisp.c (append_space_for_newline): If the default face was
12841 remapped, use the remapped face for the appended newline.
12842 (extend_face_to_end_of_line): Use the remapped default face for
12843 extending the face to the end of the line.
12844 (display_line): Call extend_face_to_end_of_line when the default
12845 face was remapped. (Bug#11068)
12847 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12849 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12851 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12853 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12855 2012-03-27 Glenn Morris <rgm@gnu.org>
12857 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12860 2012-03-26 Kenichi Handa <handa@m17n.org>
12862 * dispextern.h (struct glyph): Fix previous change. Change the
12863 bit length of glyphless.ch to 25 (Bug#11082).
12865 2012-03-26 Chong Yidong <cyd@gnu.org>
12867 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12868 (command_loop_1): Use it; inhibit selection update for
12869 handle-select-window too (Bug#8996).
12871 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12873 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12875 2012-03-25 Kenichi Handa <handa@m17n.org>
12877 * dispextern.h (struct glyph): Change the bit length of
12878 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12880 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12882 * s/ms-w32.h (tzname): Include time.h before redirecting to
12883 _tzname. Fixes the MSVC build. (Bug#9960)
12885 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12887 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12890 * xterm.c (XTread_socket): Only modify handling_signal if
12891 !SYNC_INPUT. (Bug#11080)
12893 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12895 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12896 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12897 when fetching a multibyte character consumes more bytes than
12898 CHAR_BYTES returns, due to unification of CJK characters in
12899 string_char. (Bug#11073)
12901 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12903 * process.c (wait_reading_process_output): Handle pty disconnect
12904 by refraining from sending oneself a SIGCHLD (bug#10933).
12906 2012-03-22 Chong Yidong <cyd@gnu.org>
12908 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12910 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12911 Mark string as coming from a prefix property.
12912 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12913 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12915 2012-03-21 Chong Yidong <cyd@gnu.org>
12917 * xfaces.c (Vface_remapping_alist): Doc fix.
12919 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12921 * w32proc.c (Fw32_set_console_codepage)
12922 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12925 2012-03-20 Chong Yidong <cyd@gnu.org>
12927 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12928 to reflect default non-nil value of redisplay-dont-pause.
12930 2012-03-19 Kenichi Handa <handa@m17n.org>
12932 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12933 it fit in a valid range (Bug#11003).
12935 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12937 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12938 that is not from display property, accept the row as a "cursor
12939 row" if one of the string's character has a non-nil `cursor'
12940 property. Fixes cursor positioning when there are newlines in
12941 overlay strings, e.g. in icomplete.el. (Bug#11035)
12943 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12945 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12947 2012-03-12 Chong Yidong <cyd@gnu.org>
12949 * eval.c (inhibit_lisp_code): Rename from
12950 inhibit_window_configuration_change_hook; move from window.c.
12952 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12953 * window.c (run_window_configuration_change_hook)
12954 (syms_of_window): Callers changed.

12965 is visible (Bug#10955).
12967 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12969 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12973 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12974 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12977 2012-03-03 Glenn Morris <rgm@gnu.org>
12979 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12981 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12983 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12984 position past the first glyph_row that ends at ZV. (Bug#10902)
12985 (redisplay_window, next_element_from_string): Fix typos in
12987 (redisplay_window): Pass to move_it_vertically the margin in
12988 pixels, not in screen lines.
12990 2012-03-02 Glenn Morris <rgm@gnu.org>
12992 * buffer.c (buffer-list-update-hook): Doc fix.
12994 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12996 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12997 push_it before setting up the iterator for the first overlay
12998 string, even if we have an empty string loaded.
12999 (next_overlay_string): If there's an empty string on the iterator
13000 stack, pop the stack. (Bug#10903)
13002 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13004 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13005 Suggested by Stefan Monnier in
13006 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13007 * alloc.c (widen_to_Lisp_Object): New static function.
13008 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13009 and widening them to Lisp_Objects. This would work even if
13010 USE_LSB_TAG is defined and wide integers are used, which might
13011 happen in a future version of Emacs.
13013 2012-02-25 Chong Yidong <cyd@gnu.org>
13015 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13018 * xselect.c (Fx_selection_exists_p): Doc fix.
13019 (x_clipboard_manager_save_all): Print an informative message
13020 before saving to clipboard manager.
13022 2012-02-24 Chong Yidong <cyd@gnu.org>
13024 * keyboard.c (process_special_events): Handle all X selection
13025 requests in kbd_buffer, not just the next one (Bug#8869).
13027 2012-02-23 Chong Yidong <cyd@gnu.org>
13029 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13030 call when setting menu-bar-lines and tool-bar-lines parameters.
13031 (unwind_create_frame_1): New helper function.
13033 * window.c (inhibit_window_configuration_change_hook): New var.
13034 (run_window_configuration_change_hook): Obey it.
13035 (syms_of_window): Initialize it.
13037 2012-02-22 Chong Yidong <cyd@gnu.org>
13039 * xterm.c (x_draw_image_relief): Add missing type check for
13040 Vtool_bar_button_margin (Bug#10743).
13042 2012-02-21 Chong Yidong <cyd@gnu.org>
13044 * fileio.c (Vfile_name_handler_alist): Doc fix.
13046 * buffer.c (Fget_file_buffer): Protect against invalid file
13047 handler return value.
13049 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13051 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13052 when computing $valmask.
13054 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13055 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13056 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13057 It's useless in that case, and it can cause problems on hosts
13058 that allocate halves of EMACS_INT values separately.
13059 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13060 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13061 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13062 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13063 it avoids undefined behavior on hosts where shifting right by more
13064 than the word width has undefined behavior.
13066 2012-02-19 Chong Yidong <cyd@gnu.org>
13068 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13069 (Funhandled_file_name_directory, Ffile_name_as_directory)
13070 (Fdirectory_file_name, Fexpand_file_name)
13071 (Fsubstitute_in_file_name): Protect against invalid file handler
13072 return values (Bug#10845).
13074 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13076 * .gdbinit (pitx): Fix incorrect references to fields of the

13086 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13088 2012-02-15 Chong Yidong <cyd@gnu.org>
13090 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13091 marked as special. Also, starting docstrings with * is obsolete.
13093 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13095 * gnutls.c (emacs_gnutls_write): Fix last change.

13104 * keymap.c (Fsingle_key_description): Handle char ranges.
13106 2012-02-12 Chong Yidong <cyd@gnu.org>
13108 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13109 as that creates a dangerous corner case.
13111 * window.c (Fdelete_window_internal): Invalidate the mouse
13112 highlight (Bug#9904).
13114 2012-02-12 Glenn Morris <rgm@gnu.org>

13117 (Fx_get_selection_internal, Fx_disown_selection_internal)
13118 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13119 * nsselect.m (Fx_own_selection_internal)
13120 (Fx_disown_selection_internal, Fx_selection_exists_p)
13121 (Fx_selection_owner_p, Fx_get_selection_internal):
13122 Sync docs and argument specs with the xselect.c versions.
13124 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13126 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13128 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13130 * w32select.c (Fx_selection_exists_p): Sync doc string and
13131 argument list with xselect.c. (Bug#10783)

13142 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13144 2012-02-07 Chong Yidong <cyd@gnu.org>
13146 * buffer.c (Fbuffer_local_variables)
13147 (buffer_lisp_local_variables): Handle unbound vars correctly;
13148 don't let Qunbound leak into Lisp.
13150 2012-02-07 Glenn Morris <rgm@gnu.org>
13152 * image.c (Fimagemagick_types): Doc fix.
13154 * image.c (imagemagick-render-type): Change it from a lisp object
13155 to an integer. Move the doc here from the lisp manual.
13156 Treat all values not equal to 0 the same.
13158 2012-02-06 Chong Yidong <cyd@gnu.org>
13160 * doc.c (store_function_docstring): Avoid applying docstring of

13175 Include --enable-checking, if specified, in the return value.
13177 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13179 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13180 after rounding frame sizes. (Bug#9723)

13184 * keyboard.c (adjust_point_for_property): Don't position point
13185 before BEGV. (Bug#10696)
13187 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13189 Handle overflow when computing char display width (Bug#9496).
13190 * character.c (char_width): Return EMACS_INT, not int.
13191 (char_width, c_string_width): Check for overflow when
13192 computing the width; this is possible now that individual
13193 characters can have unbounded width. Problem introduced
13194 by merge from Emacs 23 on 2012-01-19.
13196 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13198 * dbusbind.c (Fdbus_register_method): Mention the return value
13199 :ignore in the docstring.
13201 2012-02-02 Glenn Morris <rgm@gnu.org>
13203 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

13214 0, do not call append_composite_glyph.
13216 2012-02-02 Kenichi Handa <handa@m17n.org>
13218 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13220 (x_produce_glyphs): If the component of a composition is a null
13221 string, set it->pixel_width to 1 to avoid zero-width glyph.
13223 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13225 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13226 first 2 arguments are identical. This makes inserting large
13227 output from a subprocess an order of magnitude faster on
13228 MS-Windows, where all sbrk'ed memory is always contiguous.
13230 2012-01-31 Glenn Morris <rgm@gnu.org>

13268 2012-01-21 Chong Yidong <cyd@gnu.org>
13270 * floatfns.c (Fcopysign): Make the second argument non-optional,
13271 since nil is not allowed anyway.
13273 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13275 * process.c (read_process_output): Use p instead of XPROCESS (proc).

13278 2012-01-19 Martin Rudalics <rudalics@gmx.at>
13280 * window.c (save_window_save, Fcurrent_window_configuration)

13282 Rewrite doc-strings.
13284 2012-01-19 Kenichi Handa <handa@m17n.org>
13286 * character.c (char_width): New function.
13287 (Fchar_width, c_string_width, lisp_string_width):
13288 Use char_width (Bug#9496).

13308 highlight ends on a newline. (Bug#10464)
13309 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
13310 he end column for display of highlight that ends on a newline
13313 2012-01-11 Glenn Morris <rgm@gnu.org>
13315 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

13843 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13844 Otherwise, valgrind does not work on some platforms.
13845 Problem reported by Andreas Schwab in
13846 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13847 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13848 is set, removing the need for VIRT_ADDRESS_VARIES.
13849 (PURE_P): Use a more-efficient implementation that needs just one
13850 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13851 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13852 to 4 (xorl, subq, cmpq, setbe).
13853 * alloc.c (pure): Always extern now, since that's the
13854 VIRT_ADDR_VARIES behavior.

13856 consistency with the new puresize.h.
13857 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13858 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13866 behave as if the cursor position were at the window margin.
13868 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13869 and the cursor position is out of bounds, behave as if the cursor
13870 position were at the window margin. (Bug#10075)
13872 2011-11-18 Chong Yidong <cyd@gnu.org>
13874 * window.c (Fwindow_combination_limit): Make first argument

13896 compute_line_metrics.
13897 (compute_line_metrics): Call row_hash, instead of computing the
13900 * dispnew.c (verify_row_hash): Call row_hash for computing the
13901 hash code of a row, instead of duplicating code from xdisp.c.
13903 * dispextern.h (row_hash): Add prototype.
13905 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13941 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13943 * xdisp.c (display_line): Move the call to
13944 highlight_trailing_whitespace before the call to
13945 compute_line_metrics, since the latter needs to see the final
13946 faces of all the glyphs to compute ROW's hash value.
13947 Fixes assertion violations in row_equal_p. (Bug#10035)
13949 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13951 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13952 just return (bug#10044).
13954 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13956 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13957 with user-defined heap size. Bump the default size of the temacs
13958 heap to 27MB, to avoid memory warning when running temacs.

13961 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13962 current_matrix and desired_matrix. (Bug#9990)
13963 (verify_row_hash) [XASSERTS]: New function.

14010 Avoid some portability problems by eschewing 'extern inline' functions.
14011 The trivial performance wins aren't worth the portability hassles; see
14012 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14014 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14080 * xmenu.c (cleanup_widget_value_tree): New function.
14081 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14088 (window_box_width, window_box_left, window_box_left_offset)
14089 (window_box_right, window_box_right_offset): Declare extern.
14090 Otherwise, these inline functions do not conform to C99 and
14091 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14092 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14093 * intervals.c (adjust_intervals_for_insertion)

14096 (static_offset_intervals): Remove.
14097 (offset_intervals): Rewrite using the old contents of
14098 static_offset_intervals. The old version didn't conform to C99
14099 because an extern inline function contained a reference to an

14246 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14247 past the beginning of the current glyph matrix.
14249 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14251 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14252 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14253 HAVE_GTK3 (Bug#9869).
14255 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
14256 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14258 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14260 * xterm.c: Declare x_handle_net_wm_state to return int.
14261 (handle_one_xevent): Check if we are iconified but don't have
14262 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14263 (get_current_wm_state): Return non-zero if not hidden,
14264 check for _NET_WM_STATE_HIDDEN (Bug#9893).
14265 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
14266 (x_handle_net_wm_state): Return what get_current_wm_state returns.
14267 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
14269 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14271 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14272 so that this new function doesn't get optimized away by a
14273 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14275 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14277 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14279 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14281 Fix the `xbytecode' command.
14282 * .gdbinit (xprintbytestr): New command.
14283 (xwhichsymbols): Rename from `which'; all callers changed.
14284 (xbytecode): Print the byte-code string as well.
14286 2011-10-29 Kim Storm <storm@cua.dk>
14288 * alloc.c (which_symbols): New function.
14290 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14292 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14295 2011-10-29 Glenn Morris <rgm@gnu.org>
14297 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14298 Not clear what it was for, and it causes various bugs. (Bug#9839)
14300 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14302 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14303 possible random value that matches one of those tested as
14304 condition to clear the mouse face.
14306 2011-10-28 Chong Yidong <cyd@gnu.org>
14308 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14310 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14312 * window.c (make_window): Initialize phys_cursor_on_p.
14314 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14316 * lisp.h (struct Lisp_Symbol): Update comments.
14318 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14320 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14322 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14324 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14325 <oslsachem@gmail.com> for helping to debug this.
14327 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14328 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14329 (g_b_init_get_glyph_outline_w): New static variables.
14330 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14331 (GetGlyphOutlineW_Proc): New typedefs.
14332 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14333 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14335 (w32font_open_internal, compute_metrics):
14336 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14337 instead of calling the "wide" APIs directly.
14339 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14341 * w32.h (syms_of_w32font): Add prototype.
14343 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14345 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14346 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14347 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14348 (Fmove_to_window_line): Doc fix.
14350 2011-10-27 Chong Yidong <cyd@gnu.org>
14352 * process.c (make_process): Set gnutls_state to NULL.
14354 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14355 non-NULL, regardless of GNUTLS_INITSTAGE.
14356 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14357 an error. Set process slots as soon as we allocate them.
14359 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14361 2011-10-27 Chong Yidong <cyd@gnu.org>
14363 * gnutls.c (emacs_gnutls_deinit): New function.
14364 Deallocate credentials structures as well as calling gnutls_deinit.
14365 (Fgnutls_deinit, Fgnutls_boot): Use it.
14367 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14368 (deactivate_process): Call emacs_gnutls_deinit.
14370 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14372 * image.c (x_create_x_image_and_pixmap):
14373 * w32.c (sys_rename, w32_delayed_load):
14374 * w32font.c (fill_in_logfont):
14375 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14377 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14379 * w32fns.c (w32_default_color_map): New function,
14380 extracted from Fw32_default_color_map.
14381 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14383 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14385 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14387 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14389 * keyboard.c (test_undefined): New function (bug#9751).
14390 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14392 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14394 * sysdep.c (init_sys_modes): Fix the check for the controlling
14395 terminal (Bug#6649).
14397 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14399 * dispextern.h (struct bidi_it): New member next_en_type.
14401 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14402 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14403 current character, check also for next_en_type being WEAK_EN.
14404 (bidi_resolve_weak): Don't enter the expensive loop if the current
14405 position is before next_en_pos. Record the bidi type of the first
14406 non-ET, non-BN character we find, in addition to its position.
14407 (bidi_level_of_next_char): Invalidate next_en_type when
14408 next_en_pos is over-stepped.
14410 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14412 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14413 * editfns.c: Rewrite current-time-zone so that it invokes
14414 the equivalent of (format-time-string "%Z") to get the time zone name.
14415 This fixes a bug when the time zone name contains characters that
14416 need converting from the system time locale to Emacs internal format.
14417 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14418 that patch fixed format-time-string to do the conversion, but
14419 I forgot to fix current-time-zone.
14420 (format_time_string): New function, containing most of
14421 what Fformat_time_string used to contain.
14422 (Fformat_time_string): Rewrite in terms of format_time_string.
14423 This doesn't change this function's behavior.
14424 (current-time-zone): Rewrite to use format_time_string.
14425 This fixes the bug reported by Michael Schierl in
14426 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14427 Jason Rumney's 2007-06-07 change worked around this bug, but
14429 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14431 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14433 * xdisp.c (start_display): If the character at POS is displayed
14434 via a display vector, reset IT->current.dpvec_index to zero.
14435 (try_window_reusing_current_matrix): If a line ends in a display
14436 vector or the next line starts in a display vector, continue
14437 redrawing the window even though the character position of
14438 start_row was reached.
14441 2011-10-18 Chong Yidong <cyd@gnu.org>
14443 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14444 with nobreak-char-display too.
14446 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14448 Fix part 3 of bug#9771.
14449 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14450 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14451 non-neutral characters if the current character is a paragraph
14452 separator (a.k.a. Newline). This avoids running the same
14453 expensive loop twice, once when we consume the preceding newline
14454 and the other time when the line actually needs to be displayed.
14455 Avoid the loop when we see neutrals on the base embedding level
14456 following a character whose directionality is the same as the
14457 paragraph's. This avoids running the expensive loop when a line
14458 ends in a long sequence of neutrals, like control characters.
14459 Add assertion against STRONG_AL type. Slightly rearrange code
14460 that determines the type of a neutral given the first non-neutral
14462 (bidi_level_of_next_char): Set next_en_pos to zero when
14463 invalidating its info.
14465 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14467 * xdisp.c (push_display_prop): Determine whether to record string
14468 or buffer position by IT->string, not by IT->method. Allow
14469 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14470 (move_it_vertically_backward): Don't look for character position
14471 immediately after the newline when in a continuation line.
14474 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14476 * window.c (coordinates_in_window): Rewrite and delabelize
14477 vertical border check. (Bug#5357) (Bug#9618)
14479 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14481 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14482 errors in XSetWindowBorder (bug#9310).
14484 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14486 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14487 avoid crash when xmalloc overrun checking is enabled.
14489 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14491 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14492 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14493 cursor motion with <left> and <right> arrow keys.
14495 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14496 some callers set that themselves.
14498 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14500 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14501 display string and the previous row comes from the same string and
14502 is empty. (Bug#9739) (Bug#9738)
14504 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14506 * doc.c (get_doc_string): Encode file name (bug#9735).
14508 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14510 * bidi.c (bidi_level_of_next_char):
14511 * xdisp.c (get_visually_first_element): Remove old incorrect
14512 comments regarding the Unicode Line Separator character.
14514 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14516 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14518 * alloc.c (Fgc_status): Do not access beyond zombies array
14519 boundary if nzombies > MAX_ZOMBIES.
14520 * alloc.c (dump_zombies): Add missing format specifier.
14522 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14524 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14525 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14527 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14528 Some packages use them to denote characters with modifiers.
14530 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14532 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14533 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14534 matching a pp-number. Rename parameter var to var1.
14536 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14538 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14540 2011-10-08 Glenn Morris <rgm@gnu.org>
14542 * callint.c (Fcall_interactively): Give a more explicit error for the
14543 'c' case with a non-character input. (Bug#8479)
14545 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14547 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14549 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14550 lines that are hscrolled on the left.
14552 * dispnew.c (buffer_posn_from_coords): Account for a possible
14553 presence of header-line. (Bug#4426)
14555 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14557 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14558 Don't advertise functionality which we discourage or doesn't work.
14560 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14562 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14563 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14564 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14565 this makes Emacs dump core during garbage collection on rare
14566 occasions. sizeof is obviously inferior to offsetof here, so
14567 stick with offsetof.
14568 (GC_POINTER_ALIGNMENT): New macro.
14569 (mark_memory): Omit 3rd (offset) arg; caller changed.
14570 Don't assume EMACS_INT alignment is the same as pointer alignment.
14572 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14574 * keyboard.c (read_key_sequence_remapped): New var.
14575 (read_key_sequence): Compute remapping in the right buffer.
14576 (command_loop_1): Use read_key_sequence's remapping directly.
14578 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14580 * dired.c (file_name_completion): Don't expand file name.
14581 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14582 before checking file name handler.
14584 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14585 they've been requested explicitly (bug#9591).
14587 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14589 * keymap.c (Fsingle_key_description): Use make_specified_string
14590 instead of build_string to build string from push_key_description.
14593 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14595 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14596 This fixes a Y2038 bug on 64-bit hosts.
14597 * buffer.c (reset_buffer):
14598 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14599 (Fclear_buffer_auto_save_failure):
14600 Use 0, not -1, to represent an unset failure time, since time_t
14601 might not be signed.
14603 Remove dependency on glibc malloc internals.
14604 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14605 Move back here from lisp.h, but with their new implementations.
14606 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14607 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14608 * charset.c (charset_table_init): New static var.
14609 (syms_of_charset): Use it instead of xmalloc. This removes a
14610 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14611 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14612 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14613 Move back to alloc.c.
14614 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14615 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14617 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14619 * nsterm.m (windowDidResize): Call x_set_window_size only when
14620 ns_in_resize is true. Otherwise set pixelwidth/height and
14621 call change_frame_size (Bug#9628).
14623 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14625 Port --enable-checking=all to Fedora 14 x86-64.
14626 * charset.c (syms_of_charset): Also account for glibc malloc's
14627 internal overhead when calculating the initial malloc maximum.
14629 Port --enable-checking=all to Fedora 14 x86.
14630 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14632 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14633 (overrun_check_realloc, overrun_check_free):
14634 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14635 That way, xmalloc returns a properly-aligned pointer even if
14636 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14637 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14638 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14639 into account when calculating the initial malloc maximum.
14640 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14641 Move here from alloc.c, so that charset.c can use it too.
14642 Properly align; the old code wasn't right for common 32-bit hosts
14643 when configured with --enable-checking=all.
14644 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14645 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14647 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14649 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14652 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14654 * xdisp.c (compute_display_string_end): If there's no display
14655 string at CHARPOS, return -1.
14657 * bidi.c (bidi_fetch_char): When compute_display_string_end
14658 returns a negative value, treat the character as a normal
14659 character not covered by a display string. (Bug#9624)
14661 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14663 * lread.c (Fread_from_string): Fix typo in docstring.
14665 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14667 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14668 newline, reseat the iterator instead of bidi-iterating there one
14669 character at a time. (Bug#9610)
14670 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14671 TO_CHARPOS if the bidi iterator is at base embedding level.
14673 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14675 * lread.c (readevalloop): Use correct code for NBSP.
14676 (read1): Likewise. (Bug#9608)
14678 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14680 * dbusbind.c (Fdbus_register_signal): When service is not
14681 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14683 2011-09-25 Glenn Morris <rgm@gnu.org>
14685 * buffer.c (truncate-lines): Doc fix.
14687 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14689 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14690 (Fset_window_next_buffers): Doc fix.

14702 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14704 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14705 Default value is now t. Doc fix.
14707 * indent.c (Fvertical_motion): Compute and apply the overshoot
14708 logic when moving up, not only when moving down. Fix the
14709 confusing name and values of the it_overshoot_expected variable;
14710 logic changes accordingly. (Bug#9254) (Bug#9549)
14712 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14713 CHARPOS is covered by a display string which includes newlines.
14714 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14715 is covered by a display string with embedded newlines.
14717 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14719 * dbusbind.c (Fdbus_register_signal): Add match rule to
14720 Vdbus_registered_objects_table. (Bug#9581)
14721 (Fdbus_register_method, Vdbus_registered_objects_table):
14724 2011-09-24 Jim Meyering <meyering@redhat.com>
14726 do not ignore write error for any output size
14727 The previous change was incomplete.
14728 While it makes emacs --batch detect the vast majority of stdout
14729 write failures, errors were still ignored whenever the output size is
14730 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14731 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14732 && echo FAIL: ignored write error
14733 FAIL: ignored write error
14734 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14735 && echo FAIL: ignored write error
14736 FAIL: ignored write error
14737 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14739 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14741 * emacs.c (Fkill_emacs): In noninteractive mode exit
14742 non-successfully if a write error occurred on stdout. (Bug#9574)
14744 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14746 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14749 * dispextern.h (struct it): Update the comment documenting what
14752 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14754 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14755 a display string, extend search for cursor position to end of row.
14756 (find_row_edges): If the row ends in a newline from a display
14757 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14758 Handle the case of a display string with multiple newlines.
14759 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14760 non-empty line. Fixes confusing cursor motion with arrow keys at
14761 the beginning of a line that starts with whitespace.
14763 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14765 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14768 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14770 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14771 boolean (Bug#9154).
14773 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14775 * xdisp.c (display_line): Record maximum and minimum buffer
14776 positions even if no glyphs were produced (e.g., by a zero-width
14777 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14778 buffer positions that will be removed from the glyph row because
14780 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14781 column is beyond frame width: don't subtract 1 "pixel" when
14782 computing width of the stretch.
14783 (reseat_at_next_visible_line_start): Undo the change made on
14784 2011-09-17 that saved paragraph information and restored it after
14785 the call to `reseat'. (Bug#9545)
14787 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14789 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14790 and turn window cursor on if cleared (Bug#9415).
14792 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14794 * search.c (boyer_moore): Take unibyte characters from pattern
14795 literally. (Bug#9458)

14805 initialized, to pacify gcc -Wuninitialized.
14807 * fileio.c: Report proper errno when syscall falls.
14808 (Finsert_file_contents): Save and restore errno,
14809 so that report_file_error outputs the correct diagnostic.
14810 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14812 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14814 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14816 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14818 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14819 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14821 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14823 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14824 about the current paragraph and restore it after the call to reseat.
14826 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14827 (bidi_find_paragraph_start): Search back for paragraph beginning
14828 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14829 (bidi_move_to_visually_next): Only trigger paragraph-related
14830 computations when the last character is a newline or at EOB, not
14831 just any NEUTRAL_B. (Bug#9470)
14833 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14834 truncated lines if point is covered by a display string. (Bug#9524)
14836 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14838 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14839 (cons_to_x_long): New function.
14840 (lisp_data_to_selection_data): Use it. Correct the test for
14841 short-versus-long data; it was negated. Break out of vector
14842 loop, for efficiency, when a long datum is discovered.
14844 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14846 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14848 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14850 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14851 GCC PR/17406) by declaring this function with external scope.
14853 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14855 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14856 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14858 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14860 * editfns.c (Fformat): Correctly handle text properties on "%%".

14868 * xdisp.c (get_next_display_element)
14869 (fill_composite_glyph_string): Add comments about special meaning
14870 of TAB characters in a composition.
14872 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14874 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14875 This occurs when processing a multibyte format.
14876 Problem reported by Wolfgang Jenker.
14878 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14880 * xdisp.c (try_cursor_movement): Only check for exact match if
14881 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14883 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14885 Remove unused external symbols.
14886 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14887 * xdisp.c (calc_pixel_width_or_height): Now static.
14888 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

14893 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14895 * xselect.c: Use signed conversions more consistently (Bug#9498).
14896 (selection_data_to_lisp_data): Assume incoming selection data are
14897 signed integers, not unsigned. This is to be consistent with
14898 outgoing selection data, which was modified to use signed integers
14899 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14900 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14901 expects long, not unsigned long.
14903 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14905 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14906 computation of loop end. Reported by Johan Bockgård
14909 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14911 * frame.c (Fother_visible_frames_p): Function deleted.
14913 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14915 * indent.c (compute_motion): Process display vector front to back
14916 rather than the other way around. (Bug#2496)
14918 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14920 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14922 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14924 * minibuf.c (Fread_from_minibuffer): Doc fix.
14926 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14928 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14929 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14931 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14933 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14934 value for non-existent files.
14936 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14938 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14939 set its "size" to -1. This will set the modtime_size field of
14940 the corresponding buffer to -1, which is what
14941 verify-visited-file-modtime expects for files that do not exist.
14944 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14946 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14948 * lisp.h: ... from here. push_key_description is no longer
14949 defined in keyboard.c, so its declaration should not be in
14950 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14951 logically belongs with push_key_description.
14953 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14955 * buffer.h: Include <sys/types.h> instead of <time.h>.
14956 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14957 Problem reported by Herbert J. Skuhra.
14959 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14961 * xml.c (parse_region): Make the parsing work for
14962 non-comment-starting XML files again (bug#9144).
14964 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14966 * image.c (gif_load): Fix calculation of bottom and right corner.
14969 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14971 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14972 redisplay in small windows.
14974 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14976 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14978 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14980 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14981 Operate on live windows only.
14983 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14985 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14987 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14989 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14990 only under bidi iteration.
14992 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14994 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14996 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14998 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14999 Without this fix, the command to link temacs failed due to an
15000 undefined symbol __builtin_isnan. This is because
15001 /usr/include/iso/math_c99.h #defines isnan(x) to
15002 __builtin_isnan(x), but the bundled gcc, which identifies itself
15003 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15005 * floatfns.c (isnan): #undef, and then #define to a clone of
15007 (Fisnan): Always define, since it's always available now.
15008 (syms_of_floatfns): Always define isnan at the Lisp level.
15010 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15012 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15014 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15016 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15017 The previous code assumed that file offsets (off_t values) fit in
15018 EMACS_INT variables, which is not true on typical 32-bit hosts.
15019 The code messed up by falsely reporting buffer overflow in cases
15020 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15021 when "big" contains more than 2**29 bytes, even though this
15022 inserts just one byte and does not overflow the buffer.
15023 (Finsert_file_contents): Store file offsets as off_t
15024 values, not as EMACS_INT values. Check for overflow when
15025 converting between EMACS_INT and off_t. When checking for
15026 buffer overflow or for overlap, take the offsets into account.
15027 Don't use EMACS_INT for small values where int suffices.
15028 When checking for overlap, fix a typo: ZV was used where
15029 ZV_BYTE was intended.
15030 (Fwrite_region): Don't assume off_t fits into 'long'.
15031 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15033 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15035 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15037 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15039 sprintf-related integer and memory overflow issues (Bug#9412).
15041 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15042 (esprintf, exprintf, evxprintf): New functions.
15043 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15044 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15045 (modify_event_symbol): Do not assume that the length of
15046 name_alist_or_stem is safe to alloca and fits in int.
15047 (Fexecute_extended_command): Likewise for function name and binding.
15048 (Frecursion_depth): Wrap around reliably on integer overflow.
15049 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15050 since some callers pass EMACS_INT values.
15051 (Fsingle_key_description): Don't crash if symbol name contains more
15052 than MAX_ALLOCA bytes.
15053 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15054 (get_minibuffer): Arg is now EMACS_INT, not int.
15055 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15056 (esprintf, exprintf, evxprintf): New decls.
15057 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15059 * dbusbind.c (signature_cat): New function.
15060 (xd_signature, Fdbus_register_signal):
15061 Do not overrun buffer; instead, report string overflow.
15063 * dispnew.c (add_window_display_history): Don't overrun buffer.
15064 Truncate instead; this is OK since it's just a log.
15066 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15067 even if the time zone offset is outlandishly large.
15068 Don't mishandle offset == INT_MIN.
15070 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15071 when creating daemon; the previous buffer-overflow check was incorrect.
15073 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15074 which has the guts of the old verror function.
15076 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15077 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15079 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15080 (font_unparse_xlfd): Don't blindly alloca long strings.
15081 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15082 fits in int, when using sprintf. Use single snprintf to count
15083 length of string rather than counting it via multiple sprintfs;
15084 that's simpler and more reliable.
15085 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15086 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15087 sprintf, in case result does not fit in int.
15089 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15090 (fontset_from_font): Print it.
15092 * frame.c (tty_frame_count): Now printmax_t, not int.
15093 (make_terminal_frame, set_term_frame_name): Print it.
15094 (x_report_frame_params): In X, window IDs are unsigned long,
15095 not signed long, so print them as unsigned.
15096 (validate_x_resource_name): Check for implausibly long names,
15097 and don't assume name length fits in 'int'.
15098 (x_get_resource_string): Don't blindly alloca invocation name;
15099 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15102 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15103 (xg_check_special_colors, xg_set_geometry):
15104 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15106 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15107 Use esprintf, not sprintf, in case result does not fit in int.
15109 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15110 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15111 it as a large positive number.
15112 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15113 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15115 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15116 in case result does not fit in int.
15118 * print.c (float_to_string): Detect width overflow more reliably.
15119 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15120 buffer overrun. Don't assume list length fits in 'int'. Treat
15121 print length of 0 as 0, not as infinity; to be consistent with other
15122 uses of print length in this function. Don't overflow print length
15123 index. Don't assume hash table size fits in 'long', or that
15124 vectorlike size fits in 'unsigned long'.
15126 * process.c (make_process): Use printmax_t, not int, to format
15127 process-name gensyms.
15129 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15131 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15132 to avoid potential buffer overrun.
15134 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15135 if X resource line is longer than 512 bytes.
15137 * xfns.c (x_window): Make sprintf buffer a bit bigger
15138 to avoid potential buffer overrun.
15140 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15142 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15144 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15146 Integer overflow fixes for scrolling, etc.
15147 Without these, Emacs silently mishandles large integers sometimes.
15148 For example, "C-u 4294967297 M-x recenter" was treated as if
15149 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15151 * xdisp.c (try_window_id): Check Emacs fixnum range before
15152 converting to 'int'.
15154 * window.c (window_scroll_line_based, Frecenter):
15155 Check that an Emacs fixnum is in range before assigning it to 'int'.
15156 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15157 values converted from Emacs fixnums.
15158 (Frecenter): Don't wrap around a line count if it is out of 'int'
15159 range; instead, treat it as an extreme value.
15160 (Fset_window_configuration, compare_window_configurations):
15161 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15163 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15164 that can exceed INT_MAX. Check that EMACS_INT value is in range
15165 before assigning it to the (possibly-narrower) index.
15166 (match_limit): Don't assume that a fixnum can fit in 'int'.
15168 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15171 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15172 (Fvertical_motion): Don't wrap around LINES values that don't fit
15173 in 'int'. Instead, treat them as extreme values. This is good
15174 enough for windows, which can't have more than INT_MAX lines anyway.
15176 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15178 * Require libxml/parser.h to avoid compilation warning.
15180 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15182 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15183 since this reportedly can destroy thread storage.
15185 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15187 * syntax.c (find_defun_start): Update all cache variables if
15188 exiting early (Bug#9401).
15190 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15192 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15194 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15195 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15196 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15198 * term.c (tty_append_glyph): New function.
15199 (produce_stretch_glyph): Static function and its prototype deleted.
15201 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15204 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15206 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15207 when checking :margin (Bug#9390).
15208 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15209 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15210 so that the name doesn't mislead. All uses changed.
15212 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15214 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15217 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15219 * xdisp.c (move_it_to): Don't bail out early when reaching
15220 position beyond to_charpos, if we are scanning backwards.
15221 (move_it_vertically_backward): When DY == 0, make sure we get to
15222 the first character in the line after the newline.
15224 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15226 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15227 (ccl_driver): Do not generate an out-of-range pointer.
15228 (Fccl_execute_on_string): Remove unnecessary check for
15229 integer overflow, noted by Stefan Monnier in
15230 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15231 Remove a FIXME that didn't need fixing.
15232 Simplify the newly-introduced buffer reallocation code.
15234 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15236 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15238 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15240 Integer and memory overflow issues (Bug#9196).
15242 * doc.c (get_doc_string): Rework so that
15243 get_doc_string_buffer_size is the actual buffer size, rather than
15244 being 1 less than the actual buffer size; this makes xpalloc more
15247 * image.c (x_allocate_bitmap_record, cache_image):
15248 * xselect.c (Fx_register_dnd_atom):
15249 Simplify previous changes by using xpalloc.
15251 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15252 since either will do and ptrdiff_t is convenient with xpalloc.
15254 * charset.c (charset_table_size)
15255 (struct charset_sort_data.priority): Now ptrdiff_t.
15256 (charset_compare): Don't overflow if priorities differ greatly.
15257 (Fsort_charsets): Don't assume list length fits in int.
15258 Check for size-calculation overflow when allocating sort data.
15259 (syms_of_charset): Allocate an initial charset table that is
15260 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15262 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15264 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15265 The actual value is always <= INT_MAX, and leaving it unsigned made
15266 overflow checking harder.
15268 * dispextern.h (struct glyph_matrix.rows_allocated)
15269 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15270 with xpalloc. The values are still always <= INT_MAX.
15272 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15274 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15275 (SAFE_NALLOCA): New macro.
15277 * region-cache.c (struct boundary.pos, find_cache_boundary)
15278 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15279 (set_cache_region, invalidate_region_cache)
15280 (revalidate_region_cache, know_region_cache, region_cache_forward)
15281 (region_cache_backward, pp_cache):
15282 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15283 so that ptrdiff_t * can be passed to xpalloc.
15284 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15285 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15286 (pp_cache): Don't assume cache_len fits in int.
15287 * region-cache.h: Adjust extern decls to match.
15289 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15290 EMACS_INT, since either will do, for xpalloc.
15292 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15293 (xnmalloc, xnrealloc, xpalloc): New functions.
15295 * bidi.c (bidi_shelve_header_size): New constant.
15296 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15297 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15299 * bidi.c (bidi_cache_shrink):
15300 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15302 Don't update size of array until after memory allocation succeeds,
15303 because xmalloc/xrealloc may not return.
15304 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15305 now that we have proper integer overflow checking.
15306 (record_overlay_string, overlay_strings): Catch overflows when
15307 calculating size of overlay_str_buf.
15309 * callproc.c (Fcall_process): Check for size overflow when
15310 calculating size of args2.
15311 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15312 Normally we prefer signed values, but sticking with ptrdiff_t would
15313 require adding more-complicated checks.
15315 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15316 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15317 Redo buffer-overflow calculations to avoid integer overflow.
15318 Add a FIXME comment where memory seems to be over-allocated.
15320 * character.c (Fstring): Check for size-calculation overflow.
15322 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15323 unnecessary integer overflow. Check for size overflow.
15324 (encode_coding_object): Don't update size until xmalloc succeeds.
15326 * composite.c (get_composition_id): Check for overflow in glyph
15327 length calculations.
15329 Integer and memory overflow fixes for display code.
15330 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15331 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15332 (scrolling_window): Check for overflow in size calculations.

15344 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15345 (get_doc_string): Check for size calculation overflow.
15346 Don't update size until allocation succeeds.
15347 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15348 EMACS_INT, where ptrdiff_t will do.
15349 (Fsubstitute_command_keys): Check for string overflow.
15351 * editfns.c (set_time_zone_rule): Don't assume environment length
15353 (message_length): Now ptrdiff_t, not int.
15354 (Fmessage_box): Don't update size until allocation succeeds.
15355 Don't assume message length fits in int.
15356 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15358 * emacs.c (main): Do not reallocate argv, since there is a null at
15359 the end that can be overwritten, and this way there's no need to
15360 worry about size-calculation overflow.
15361 (sort_args): Check for size-calculation overflow.
15363 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15365 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15367 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15368 (x_set_scroll_bar_width, x_figure_window_size):
15369 Check for integer overflow.
15370 (x_set_alpha): Do not assume XINT fits in int.
15372 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15373 This is for the members text_lines, text_cols, total_lines, total_cols,
15374 where the system imposes an 'int' limit.
15376 * fringe.c (Fdefine_fringe_bitmap):
15377 Don't update size until alloc works.
15379 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15380 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15382 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15383 Check for size-calculation overflow.
15384 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15385 do, as we prefer signed integers.
15386 (id_to_widget.max_size, id_to_widget.used)
15387 (xg_store_widget_in_map, xg_remove_widget_from_map)
15388 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15389 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15390 Use and return ptrdiff_t, not int.
15391 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15392 * gtkutil.h: Change prototypes to match the above.
15394 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15395 are duplicate now that they've been promoted to lisp.h.
15396 (x_allocate_bitmap_record, x_alloc_image_color)
15397 (make_image_cache, cache_image, xpm_load):
15398 Don't update size until alloc is done.
15399 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

15402 (ct_colors_allocated_max): New constant.
15403 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

15409 Use ptrdiff_t, not int, to count maps.
15410 (read_char_minibuf_menu_prompt): Check for overflow in size
15411 calculations. Don't update size until allocation succeeds.
15412 Redo calculations to avoid overflow.
15413 * keyboard.h: Change prototypes to match the above.
15415 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15417 (current_minor_maps): Check for size calculation overflow.
15418 * keymap.h: Change prototypes to match the above.
15420 * lread.c (read1, init_obarray): Don't update size until alloc done.

15425 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15426 Now ptrdiff_t, not int.
15427 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15439 (Fset_match_data): Don't assume list lengths fit in 'int'.
15441 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15442 for command line length. Do not attempt to address one before the
15443 beginning of an array, as that's not portable.
15445 * term.c (max_frame_lines): Remove; unused.
15446 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15448 (encode_terminal_code, calculate_costs): Check for size

15452 done. Redo calculations to avoid overflow.
15453 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15455 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15456 subtracting pointers.
15457 (gobble_line): Check for overflow more carefully. Don't update size
15460 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

15471 Use ptrdiff_t, not int, for sizes.
15472 (Finternal_make_lisp_face, cache_face):
15473 Check for size calculation overflow.
15474 (cache_face): Treat size calculation overflows as if they were
15475 memory exhaustion (the usual treatment), rather than aborting.
15477 * xfns.c (x_encode_text, x_set_name_internal)
15478 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15479 sizes, since they can exceed INT_MAX in size. Check for size
15480 calculation overflow.

15483 (xg_select): Check for size calculation overflow.
15484 Don't update size until alloc done.
15486 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15487 as sprintf is limited to int lengths.
15489 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15490 (X_LONG_MIN): New macros.
15491 Use them to make the following changes clearer.
15492 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15493 This change doesn't affect the value now, but it may help remind
15494 future maintainers not to raise the value too much later.
15495 (SELECTION_QUANTUM): Remove, replacing with ...
15496 (selection_quantum): ... new function, which avoids overflow.
15498 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15499 assumption that selection length fits in 'int'.

15507 Redo calculations to avoid overflow.
15508 (x_reply_selection_request): When sending hint, ceiling it at
15509 X_LONG_MAX rather than relying on wraparound overflow to send
15511 (x_get_window_property, receive_incremental_selection)
15512 (lisp_data_to_selection_data, x_property_data_to_lisp):
15513 Check for size-calculation overflow.
15514 (x_get_window_property, receive_incremental_selection)
15515 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15516 Don't store size until memory allocation succeeds.
15517 (x_get_window_property): Plug memory leak on memory exhaustion.
15518 Don't double-block input; malloc is safe here. Don't assume 2**34
15519 - 4 fits in unsigned long. Add an xassert to check
15520 XGetWindowProperty overflow. Be more careful about overflow
15521 calculations, and distinguish size from memory overflow better.
15522 (receive_incremental_selection): When tracing, don't assume
15523 unsigned int is less than INT_MAX.
15524 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15525 harmful) conversions of unsigned short to int.
15526 (lisp_data_to_selection_data): Don't assume that integers
15527 in the range -65535 through -1 fit in an X unsigned short.
15528 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15529 result parameters unless successful. Rely on cons_to_unsigned
15530 to report problems with elements; the old code wasn't right anyway.
15531 (x_check_property_data): Check for int overflow; we cannot use
15532 a wider type due to X limits.
15533 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15535 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15564 * image.c (xpm_get_color_table_h):
15565 * lisp.h (hash_lookup, hash_put):
15566 * minibuf.c (Ftest_completion):
15567 Use ptrdiff_t for hash table indexes, not int (which is too
15568 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15569 32-bit --with-wide-int hosts).
15571 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15572 Add a FIXME comment about memory leaks.
15573 (syms_of_charset): Don't assume xmalloc returns.
15575 Don't assume that stated character widths fit in int.

15577 * character.h (CHAR_WIDTH):
15578 * indent.c (MULTIBYTE_BYTES_WIDTH):
15579 Use sanitize_char_width to avoid undefined and/or bad behavior
15580 with outlandish widths.
15581 * character.h (sanitize_tab_width): Rename from sanitize_width,
15582 now that we have two such functions. All uses changed.
15583 (sanitize_char_width): New inline function.
15585 Don't assume that tab-width fits in int.
15586 * character.h (sanitize_width): New inline function.

15593 * fileio.c: Integer overflow issues with file modes.
15594 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15596 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15597 Remove unreachable code.
15598 (read_hex, load_charset_map_from_file): Check for integer overflow.
15600 * xterm.c: Don't go over XClientMessageEvent limit.
15601 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15602 (x_send_scroll_bar_event): Likewise. Check that the size does not
15603 exceed limits imposed by XClientMessageEvent, as well as the usual
15604 ptrdiff_t and size_t limits.
15606 * keyboard.c: Overflow, signedness and related fixes.
15607 (make_lispy_movement): Use same integer type in forward decl
15608 that is used in the definition.
15609 (read_key_sequence, keyremap_step):
15610 Change bufsize argument back to int, undoing my 2011-03-30 change.
15611 We prefer signed types, and int is wide enough here.
15612 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15613 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15614 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15615 length, not size_t. Use ptrdiff_t for index, not int.
15616 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15617 possibility of integer overflow.
15619 Overflow, signedness and related fixes for images.
15621 * dispextern.h (struct it.stack[0].u.image.image_id)
15622 (struct_it.image_id, struct image.id, struct image_cache.size)

15638 when the callers expect that.
15639 (image_ascent): Redo ascent calculation to avoid int overflow.
15640 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15641 (lookup_image): Remove unnecessary tests.
15642 (xbm_image_p): Locals are now of int, not EMACS_INT,
15643 since parse_image_check makes sure they fit into int.
15644 (png_load, gif_load, svg_load_image):
15645 Prefer int to unsigned where either will do.
15646 (tiff_handler): New function, combining the cores of the
15647 old tiff_error_handler and tiff_warning_handler.
15648 This function is rewritten to use vsnprintf and thereby avoid
15649 stack buffer overflows. It uses only the features of vsnprintf
15650 that are common to both POSIX and native Microsoft.
15651 (tiff_error_handler, tiff_warning_handler): Use it.
15652 (tiff_load, gif_load, imagemagick_load_image):
15653 Don't assume :index value fits in 'int'.
15654 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15655 (imagemagick_load_image): Check that crop parameters fit into
15656 the integer types that MagickCropImage accepts. Don't assume
15657 Vimagemagick_render_type has a nonnegative value. Don't assume
15658 size_t fits in 'long'.
15659 (gs_load): Use printmax_t to print the widest integers possible.
15660 Check for integer overflow when computing image height and width.

15672 handle_single_display_spec, not just 1 or zero.
15673 (handle_single_display_spec): If the display spec is of the form
15674 `(space ...)', and specifies display in the text area, return 2
15676 (try_cursor_movement): Check for the need to scroll more
15677 accurately, and prefer exact match for point under bidi.
15678 Don't advance `row' beyond the last row of the window.
15680 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15681 into disp_prop; all users changed.
15683 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

15695 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15696 buffers, return left-to-right.
15697 (set_cursor_from_row): Consider candidate row a win if its glyph
15698 represents a newline and point is on that newline. Fixes cursor
15699 positioning on the newline at EOL of R2L text within L2R
15700 paragraph, and vice versa.
15701 (try_cursor_movement): Check continued rows, in addition to
15702 continuation rows. Fixes unwarranted scroll when point enters a
15703 continued line of R2L text within an L2R paragraph, or vice versa.
15704 (cursor_row_p): Consider the case of point being equal to
15705 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15706 from the end of a short line to the beginning of a continued line
15707 of R2L text within L2R paragraph.
15708 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15709 composed characters.

15726 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15727 extra slot even if the purpose is char-code-property-table.
15729 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15731 * xdisp.c (redisplay_window): When computing centering_position,
15732 account for the height of the header line. (Bug#8874)
15734 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15735 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15736 candidate is selected by the mouse, and that candidate has a
15737 composed character under the mouse.
15739 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15740 coordinates reported by pos-visible-in-window-p for a composed
15741 character in column zero.
15743 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15745 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15747 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15749 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15750 consider it a hit if to_charpos is anywhere in the range of the
15751 composed buffer positions.
15753 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15755 * image.c (gif_load): Don't assume that each subimage has the same
15756 dimensions as the base image. Handle disposal method that is
15757 "undefined" by the gif spec (Bug#9335).
15759 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15761 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15766 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15767 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15768 from an Org mode buffer to a Speedbar frame.
15770 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15771 a composition, take its buffer position from IT->cmp_it.charpos.
15772 Fixes cursor positioning at the beginning of a line that begins
15773 with a composed character.
15775 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15777 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15778 character bidirectional type, use STRONG_L instead. Fixes crashes
15779 in a buffer produced by `describe-categories'.
15781 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15782 members before the level stack, so they would be saved and
15783 restored when copying iterator state. Fixes incorrect reordering
15784 around TABs covered by display properties.
15786 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15788 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15858 * xdisp.c (move_it_in_display_line_to): Don't invoke
15859 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15860 ppos_it. Fixes vertical cursor motion when line beginning is
15861 covered by an image. (Bug#9296)
15863 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15865 * nsterm.h (ns_run_ascript): Declare.

15870 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15871 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15872 the event loop. Get status from as_status (Bug#7276).
15874 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15875 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15876 the event loop (Bug#7276).
15878 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15902 (Fnetwork_interface_list): Allocate in increments of bytes instead
15903 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15904 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15906 (struct ifflag_def): notrailers is smart on OSX.
15907 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15908 Get hardware address with getifaddrs if available.
15910 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15912 * xdisp.c (iterate_out_of_display_property): xassert that
15913 IT->position is set to within IT->object's boundaries. Break from

15916 Set IT->current to match the bidi iterator unconditionally.
15917 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15918 entry. Force push_it to save on the stack the current
15919 buffer/string position, to be restored by pop_it. Fix flags in
15920 the iterator structure wrt the object coming from a display
15921 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15922 properties. (Bug#9284)
15924 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15926 * fontset.c (fontset_get_font_group): Add proper type checks.

15954 restore_point_unwind (Bug#5984).
15956 2011-08-07 Juri Linkov <juri@jurta.org>
15958 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

15963 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15964 display property strides EOL and includes a newline, as in
15965 longlines-mode. (Bug#9254)
15966 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15967 word-wrap under bidirectional display. (Bug#9224)
15969 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15970 is non-zero, even if the data buffer is NULL. Fixes a crash in
15971 vertical-motion with longlines-mode. (Bug#9254)
15973 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15975 * bidi.c <bidi_cache_total_alloc>: Now static.

15981 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15982 amount allocated this far in `bidi_cache_total_alloc'.
15983 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15984 non-zero, only free the data buffer without restoring the cache
15985 contents. All callers changed.
15987 * dispextern.h (bidi_unshelve_cache): Update prototype.
15989 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15990 (move_it_in_display_line, move_it_to)
15991 (move_it_vertically_backward, move_it_by_lines): Replace the call
15992 to xfree to an equivalent call to bidi_unshelve_cache.
15993 (move_it_in_display_line_to): Fix logic of returning
15994 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15996 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15998 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

16045 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16046 for a display string or property. If found, set DISP_PROP_P
16049 * bidi.c (bidi_fetch_char): Accept an additional argument
16050 DISP_PROP_P, and pass it to compute_display_string_pos.
16051 Only handle text covered by a display string if DISP_PROP_P is returned
16052 non-zero. All callers of bidi_fetch_char changed.
16054 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16056 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16058 2010-12-03 Don March <don@ohspite.net>
16060 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16061 last character M-[char] is translated to ESC [char] (bug#7541).
16063 2011-08-02 Kenichi Handa <handa@m17n.org>
16065 * lisp.h (uniprop_table): Extern it.
16067 * chartab.c (uniprop_table): Make it non-static.
16069 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16071 * xdisp.c (forward_to_next_line_start): Accept additional argument
16072 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16074 (reseat_at_next_visible_line_start): Use the bidi iterator state
16075 returned by forward_to_next_line_start to restore the state of
16076 it->bidi_it after backing up to previous newline. (Bug#9212)
16078 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16080 * regex.c (re_comp): Protoize.
16081 (re_exec): Fix return type.
16082 (regexec): Fix type of `ret'. (Bug#9203)
16084 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16086 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16087 This is needed if max-image-size is a floating-point number.
16089 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16091 * print.c (print_object): Print empty symbol as ##.
16093 * lread.c (read1): Read ## as empty symbol.
16095 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16097 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16098 setting frame foreground color (Bug#9175).
16099 (x_set_background_color): Likewise.
16101 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16102 contents (Bug#9176).
16103 (EmacsTooltip -init): Remove bezels and add shadows to
16106 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16107 or scroll bar (Bug#8470).
16109 * nsfont.m (nsfont_open): Remove assignment to voffset and
16110 unnecessary vars hshink, expand, hd, full_height, min_height.
16111 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16113 * nsterm.h (nsfont_info): Remove voffset field.
16115 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16117 Implement strike-through and overline on NextStep (Bug#8863).
16119 * nsfont.m (nsfont_open): Use underline position provided by font,
16120 instead of hard-coded value of 2.
16121 (nsfont_draw): Call ns_draw_text_decoration instead.
16123 * nsterm.h: Add declaration for ns_draw_text_decoration.
16125 * nsterm.m (ns_draw_text_decoration): New function for drawing
16126 underline, overline, and strike-through.
16127 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16128 ns_draw_text_decoration. Change treatment of cursor drawing to
16129 accommodate underlining, etc.
16131 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16133 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16136 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16138 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16139 Without this fix, if a signal arrives just after memory fills up,
16140 'malloc' might be invoked reentrantly.
16142 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16143 In other words, assume that every image size is allowed, on non-X
16144 hosts. This assumption is probably wrong, but it lets Emacs compile.
16146 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16148 * regex.c (re_iswctype): Convert return values to boolean.
16150 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16152 * xdisp.c (compute_display_string_pos): Don't use cached display
16153 string position if the buffer had its restriction changed.
16156 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16158 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16160 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16162 Integer signedness and overflow and related fixes. (Bug#9079)
16164 * bidi.c: Integer size and overflow fixes.
16165 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16166 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16167 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16168 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16169 (bidi_find_other_level_edge):
16170 Use ptrdiff_t instead of EMACS_INT where either will do.
16171 This works better on 32-bit hosts configured --with-wide-int.
16172 (bidi_cache_ensure_space): Check for size-calculation overflow.
16173 Use % rather than repeated addition, for better worst-case speed.
16174 Don't set bidi_cache_size until after xrealloc returns, because it
16176 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16177 (bidi_cache_ensure_space): Also check that the bidi cache size
16178 does not exceed that of the largest Lisp string or buffer. See Eli
16179 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16181 * alloc.c (__malloc_size_t): Remove.
16182 All uses replaced by size_t. See Andreas Schwab's note
16183 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16185 * image.c: Improve checking for integer overflow.
16186 (check_image_size): Assume that f is nonnull, since
16187 it is always nonnull in practice. This is one less thing to
16188 worry about when checking for integer overflow later.
16189 (x_check_image_size): New function, which checks for integer
16190 overflow issues inside X.
16191 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16192 This removes the need for a memory_full check.
16193 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16194 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16195 (xbm_read_bitmap_data): Change locals back to 'int', since
16196 their values must fit in 'int'.
16197 (xpm_load_image, png_load, tiff_load):
16198 Invoke x_create_x_image_and_pixmap earlier,
16199 to avoid much needless work if the image is too large.
16200 (tiff_load): Treat overly large images as if
16201 x_create_x_image_and_pixmap failed, not as malloc failures.
16202 (gs_load): Use x_check_image_size.
16204 * gtkutil.c: Omit integer casts.
16205 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16206 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16208 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16210 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16211 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16212 would wrongly return t on a 64-bit host.
16214 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16215 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16216 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16217 and therefore cause GCC to emit a bogus diagnostic in some cases.
16219 * image.c: Integer signedness and overflow and related fixes.
16220 This is not an exhaustive set of fixes, but it's time to
16221 record what I've got.
16222 (lookup_pixel_color, check_image_size): Remove redundant decls.
16223 (check_image_size): Don't assume that arbitrary EMACS_INT values
16224 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16225 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16226 (tiff_load, imagemagick_load_image):
16227 Check for overflow in size calculations.
16228 (x_create_x_image_and_pixmap): Remove unnecessary test for
16229 xmalloc returning NULL; that can't happen.
16230 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16231 (xpm_color_bucket): Use better integer hashing function.
16232 (xpm_cache_color): Don't possibly over-allocate memory.
16233 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16234 (gif_memory_source):
16235 Use ptrdiff_t, not int or size_t, to record sizes.
16236 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16237 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16238 either works, as we prefer signed integers.
16239 (tiff_read_from_memory, tiff_write_from_memory):
16240 Return tsize_t, not size_t, since that's what the TIFF API wants.
16241 (tiff_read_from_memory): Don't fail simply because the read would
16242 go past EOF; instead, return a short read.
16243 (tiff_load): Omit no-longer-needed casts.
16244 (Fimagemagick_types): Don't assume size fits into 'int'.
16246 Improve hashing quality when configured --with-wide-int.
16247 * fns.c (hash_string): New function, taken from sxhash_string.
16248 Do not discard information about ASCII character case; this
16249 discarding is no longer needed.
16250 (sxhash-string): Use it. Change sig to match it. Caller changed.
16251 * lisp.h: Declare it.
16252 * lread.c (hash_string): Remove, since we now use fns.c's version.
16253 The fns.c version returns a wider integer if --with-wide-int is
16254 specified, so this should help the quality of the hashing a bit.
16256 * emacs.c: Integer overflow minor fix.
16257 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16258 Define only if GNU_LINUX.
16259 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16261 * dispnew.c: Integer signedness and overflow fixes.
16262 Remove unnecessary forward decls, that were a maintenance hassle.
16263 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16265 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16266 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16267 (prepare_desired_row, line_draw_cost):
16268 Use int, not unsigned, where either works.
16269 (save_current_matrix, restore_current_matrix):
16270 Use ptrdiff_t, not size_t, where either works.
16271 (init_display): Check for overflow more accurately, and without
16272 relying on undefined behavior.
16274 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16275 Remove, replacing with the new symbols in lisp.h. All uses changed.
16276 * fileio.c (make_temp_name):
16277 * filelock.c (lock_file_1, lock_file):
16278 * xdisp.c (message_dolog):
16279 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16280 Use pMd etc. instead.
16281 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16282 replacing the pWIDE etc. symbols removed from editfns.c.
16284 * keyboard.h (num_input_events): Now uintmax_t.
16285 This is (very slightly) less likely to mess up due to wraparound.
16288 * buffer.c: Integer signedness fixes.
16289 (alloc_buffer_text, enlarge_buffer_text):
16290 Use ptrdiff_t rather than size_t when either will do, as we prefer
16293 * alloc.c: Integer signedness and overflow fixes.
16294 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16295 (__malloc_size_t): Default to size_t, not to int.
16296 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16297 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16298 Prefer ptrdiff_t to size_t when either would do, as we prefer
16300 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16301 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16302 Now const. Initialize with values that are in range even if char
16304 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16305 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16306 These functions do the right thing with sizes > 2**32.
16307 (check_depth): Now ptrdiff_t, not int.
16308 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16309 Adjust to new way of storing sizes. Check for size overflow bugs
16311 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16312 slightly wrong anyway, as it missed one instance of
16313 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16314 (refill_memory_reserve): Omit needless cast to size_t.
16315 (mark_object_loop_halt): Mark as externally visible.
16317 * xselect.c: Integer signedness and overflow fixes.
16318 (Fx_register_dnd_atom, x_handle_dnd_message):
16319 Use ptrdiff_t, not size_t, since we prefer signed.
16320 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16321 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16322 x_dnd_atoms_size and x_dnd_atoms_length.
16324 * doprnt.c: Prefer signed to unsigned when either works.
16326 * doprnt.c (doprnt):
16328 * xdisp.c (vmessage):
16329 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16330 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16331 prefer signed arithmetic to avoid comparison confusion.
16332 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16333 but is a bit tricky.
16335 Assume freestanding C89 headers, string.h, stdlib.h.
16336 * data.c, doprnt.c, floatfns.c, print.c:
16337 Include float.h unconditionally.
16338 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16339 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16340 * regex.c: Likewise for stddef.h, string.h.
16341 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16342 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16343 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16344 (STDC_HEADERS): Remove obsolete defines.
16345 * sysdep.c: Include limits.h unconditionally.
16347 Assume support for memcmp, memcpy, memmove, memset.
16348 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16349 * regex.c (memcmp, memcpy):
16350 Remove; we assume C89 now.
16352 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16353 (__malloc_safe_bcopy): Remove; no longer needed.
16355 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16356 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16357 well either way, and we prefer signed to unsigned.
16359 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16361 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16362 closes the connection while we're reading (bug#9182).
16364 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16366 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16367 are specified (Bug#9168).
16369 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16371 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16372 Found by GCC static checking and --with-wide-int on a 32-bit host.
16374 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16376 * xdisp.c (compute_display_string_pos): Fix logic of caching
16377 previous display string position. Initialize cached_prev_pos to
16378 -1. Fixes slow-down at the beginning of a buffer.
16380 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16382 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16383 for attrs[LFACE_FONTSET_INDEX].
16385 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16387 * xml.c (parse_region): Remove unused local
16388 that was recently introduced.
16390 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16392 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16393 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16395 * xdisp.c (move_it_in_display_line_to): Record the best matching
16396 position for TO_CHARPOS while scanning the line, and restore it on
16397 exit if none of the characters scanned was an exact match.
16398 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16399 when exact match is impossible due to invisible text, and the
16400 lines are truncated.
16402 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16404 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16407 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16409 Fix a significant slow-down of cursor motion with C-n, C-p,
16410 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16411 auto-repeat under bidi redisplay in fontified buffers.
16412 * xdisp.c (compute_stop_pos_backwards): New function.
16413 (next_element_from_buffer): Call compute_stop_pos_backwards to
16414 find a suitable prev_stop when we find ourselves before
16416 (reseat): Don't look for prev_stop, as that could mean a very long
16418 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16419 <cached_disp_overlay_modiff>: Cache for last found display string
16421 (compute_display_string_pos): Return the cached position if asked
16422 about the same buffer in the same area of character positions, and
16423 the buffer wasn't changed since the time the display string
16424 position was cached.
16426 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16428 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16429 is an integer, which is important for empty lines. (Bug#9149)
16431 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16433 * frame.c (Fmodify_frame_parameters): In tty case, update the
16434 default face if necessary (Bug#4238).
16436 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16438 * editfns.c (Fstring_to_char): No need to explain what a character
16439 is in the docstring (Bug#6576).
16441 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16443 * xml.c (parse_region): Make sure we always return a tree.
16445 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16447 * xml.c (parse_region): If a document contains only comments,
16450 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16452 * xml.c (make_dom): Return comments, too.
16454 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16457 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16458 and the surrounding thread.
16459 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16460 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16461 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16463 * s/openbsd.h (BROKEN_SIGIO): Define.
16464 * unexelf.c (unexec) [__OpenBSD__]:
16465 Don't update the .mdebug section of the Alpha COFF symbol table.
16467 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16469 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16472 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16474 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16475 This fixes some race conditions on the permissions of any newly
16478 * alloc.c (valid_pointer_p): Use pipe, not open.
16479 This fixes some permissions issues when debugging.
16481 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16482 If fchown fails to set both uid and gid, try to set just gid,
16483 as that is sometimes allowed. Adjust the file's mode to eliminate
16484 setuid or setgid bits that are inappropriate if fchown fails.
16486 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16488 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16489 to compare Lisp_Objects.

16504 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16505 This works around a problem with the previous change to Fcopy_file.
16506 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16507 and without this change, GCC might complain about discarding
16508 fchown's return value.
16510 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16512 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

16535 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16537 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16538 quotes the next character, and doesn't affect other longer
16539 sequences (bug#8935).
16541 * lread.c (syms_of_lread): Clarify that is isn't only
16542 `eval-buffer' and `eval-defun' that's affected by
16543 `lexical-binding' (bug#8460).

16553 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16554 (elsz): Now a signed constant, not a size_t var. We prefer signed
16555 types to unsigned, to avoid integer comparison confusion. Without
16556 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16557 "cannot optimize loop, the loop counter may overflow", a symptom
16559 * indent.c (Fvertical_motion): Mark locals as initialized.
16560 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16562 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

16606 the iterator is before prev_stop.
16607 (init_iterator): Initialize bidi_p from the default value of

16648 pushed the iterator stack, restore the internal state of the bidi
16649 iterator by calling bidi_pop_it same number of times.
16650 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16651 and we are bidi-iterating, don't decrement the iterator position;
16652 instead, set the first_elt flag in the bidi iterator, to produce
16654 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16655 (push_display_prop): xassert that we are iterating a buffer.

16659 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16660 correctly. Don't assume unibyte strings are not bidi-reordered.

17084 (clone_per_buffer_values): Don't assume that

17086 This isn't true in general, and it's particularly not true
17087 if Emacs is configured with --with-wide-int.
17088 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17089 New macros, used in the buffer.c change.

17125 Random fixes. E.g., (random) never returned negative values.
17126 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17127 subseconds part to the entropy, as that's a bit more random.
17128 Prefer signed to unsigned, since the signedness doesn't matter and
17129 in general we prefer signed. When given a limit, use a
17130 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17131 latter isn't right if USE_2_TAGS_FOR_INTS.
17132 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17133 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17135 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17137 * textprop.c (text_property_stickiness):
17138 Obey Vtext_property_default_nonsticky.

17145 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17146 This is more efficient than Ffile_directory_p and avoids a minor race.
17148 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17150 * buffer.c (Foverlay_put): Say what the return value is
17153 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17154 is a directory before asking whether to use the file name
17156 (barf_or_query_if_file_exists): Make the "File is a directory"
17157 error be more correct.
17159 * fns.c (Frequire): Remove the mention of the .gz files, since
17160 that's installation-specific, but keep the mention of
17161 `get-load-suffixes'.

17165 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17173 Qgnutls_bootprop_verify_error (which is no longer used).
17175 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17176 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17177 Also (re)move comments that are misplaced or no longer relevant.
17179 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17181 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17202 leave any prefix arg for the up event (Bug#1586).
17204 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
17206 * lread.c (syms_of_lread): Mention single symbols defined by
17207 `defvar' or `defconst' (bug#7154).
17209 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17210 (Frequire): Mention get-load-suffixes.

17240 (syms_of_keymap): Defsubr make-composed-keymap.
17241 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17278 * eval.c (struct backtrace): Simplify and port the data structure.
17279 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17280 signed bit field, as this assumption is not portable and it makes
17281 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17282 "char debug_on_exit : 1" as this is not portable either; instead,
17283 use the portable "unsigned int debug_on_exit : 1". Remove unused
17284 member evalargs. Remove obsolete comments about cc bombing out.
17286 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17363 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.
17366 2011-06-26 Eli Zaretskii <eliz@gnu.org>
17368 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
17369 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
17372 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
17374 * process.c (wait_reading_process_output): Bypass select if
17375 waiting for a cell while ignoring keyboard input, and input is
17376 pending. Suggested by Jan Djärv (Bug#8869).
17378 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
17380 Use gnulib's dup2 module instead of rolling our own.
17381 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17383 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17385 * dispnew.c (scrolling_window): Before scrolling, turn off a
17386 mouse-highlight in the window being scrolled.
17388 2011-06-24 Juanma Barranquero <lekktu@gmail.com>

17448 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17450 Integer and buffer overflow fixes (Bug#8873).
17452 * print.c (printchar, strout): Check for string overflow.
17453 (PRINTPREPARE, printchar, strout):
17454 Don't set size unless allocation succeeds.
17456 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17457 for sizes. Check for string overflow more accurately.
17458 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17460 * macros.c: Integer and buffer overflow fixes.
17461 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17462 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17463 Use ptrdiff_t, not int, for sizes.
17464 Don't increment bufsize until after realloc succeeds.
17465 Check for size-calculation overflow.
17466 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17468 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17470 * lread.c: Integer overflow fixes.
17471 (read_integer): Radix is now EMACS_INT, not int,
17472 to improve quality of diagnostics for out-of-range radices.
17473 Calculate buffer size correctly for out-of-range radices.
17474 (read1): Check for integer overflow in radices, and in
17475 read-circle numbers.
17476 (read_escape): Avoid int overflow.
17477 (Fload, openp, read_buffer_size, read1)
17478 (substitute_object_recurse, read_vector, read_list, map_obarray):
17479 Use ptrdiff_t, not int, for sizes.
17480 (read1): Use EMACS_INT, not int, for sizes.
17481 Check for size overflow.
17483 * image.c (cache_image): Check for size arithmetic overflow.

17492 (read_escape): Check for hex character overflow.
17494 2011-06-22 Leo Liu <sdl.web@gmail.com>
17496 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17497 Move to minibuffer.el.
17499 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17501 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17502 The following patches are for when GLYPH_DEBUG && !XASSERT.
17503 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17504 * dispnew.c (flush_stdout):
17505 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17506 Mark as externally visible.
17507 * dispnew.c (check_window_matrix_pointers): Now static.
17508 * dispnew.c (window_to_frame_vpos):
17509 * xfns.c (unwind_create_frame):
17510 * xterm.c (x_check_font): Remove unused local.
17511 * scroll.c (CHECK_BOUNDS):
17512 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17513 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17514 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17515 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17516 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17518 (debug_method_add): Use va_list and vsprintf rather than relying
17519 on undefined behavior with wrong number of arguments.
17520 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17521 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17522 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17523 since we're not interested in debugging glyphs with old libraries.
17524 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17525 GCC 4.6.0's static checking.
17527 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17529 Integer overflow and signedness fixes (Bug#8873).

17538 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17539 (x_create_bitmap_from_xpm_data):
17540 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17541 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17543 * xfaces.c (load_pixmap):
17544 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17545 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17546 (.bitmaps_last, struct x_output.icon_bitmap):
17547 Use ptrdiff_t, not int, for bitmap indexes.
17548 (x_allocate_bitmap_record): Check for size overflow.
17549 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17551 Use ptrdiff_t, not int, for overlay counts.
17552 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17553 * editfns.c (overlays_around, get_pos_property):
17554 * textprop.c (get_char_property_and_overlay):
17555 * xdisp.c (next_overlay_change, note_mouse_highlight):
17556 * xfaces.c (face_at_buffer_position):
17557 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17558 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17559 (Fnext_overlay_change, Fprevious_overlay_change)
17560 (mouse_face_overlay_overlaps, Foverlays_in):
17561 Use ptrdiff_t, not int, for sizes.
17562 (overlays_at, overlays_in): Check for size-calculation overflow.
17564 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17566 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17567 (x_session_initialize): Do not assume string length fits in int.
17569 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17570 This is unlikely, but can occur if DPI is outlandish.
17572 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17573 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17575 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17576 * xrdb.c (magic_file_p, search_magic_path):
17577 Omit last arg SUFFIX; it was always 0. All callers changed.
17578 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17580 * xfont.c (xfont_match): Avoid need for strlen.
17582 * xfns.c: Don't assume strlen fits in int.
17583 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17585 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17586 not unsigned long, as we prefer signed integers. All callers changed.
17587 Detect integer overflow in repeat count.
17588 (message_dolog): Don't assume print length fits in 39 bytes.
17589 (display_mode_element): Don't assume strlen fits in int.
17591 * termcap.c: Don't assume sizes fit in int and never overflow.
17592 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17593 (gobble_line): Check for size-calculation overflow.
17595 * minibuf.c (Fread_buffer):
17596 * lread.c (intern, intern_c_string):
17597 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17600 * keyboard.c (parse_tool_bar_item):
17601 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17603 * font.c: Don't assume string length fits in int.
17604 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17605 Use ptrdiff_t, not int.
17606 (font_intern_prop): Don't assume string length fits in int.
17607 Don't assume integer property fits in fixnum.
17608 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17610 * filelock.c: Fix some buffer overrun and integer overflow issues.
17611 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17612 Reformulate so as not to need the command string.
17613 Invoke gzip -cd rather than gunzip, as it's more portable.
17614 (lock_info_type, lock_file_1, lock_file):
17615 Don't assume pid_t and time_t fit in unsigned long.
17616 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17617 (current_lock_owner): Prefer signed type for sizes.
17618 Use memcpy, not strncpy, where memcpy is what is really wanted.
17619 Don't assume (via atoi) that time_t and pid_t fit in int.
17620 Check for time_t and/or pid_t out of range, e.g., via a network share.
17621 Don't alloca where an auto var works fine.
17623 * fileio.c: Fix some integer overflow issues.
17624 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17625 Don't assume string length fits in int.
17626 (directory_file_name): Don't assume string length fits in long.
17627 (make_temp_name): Don't assume pid fits in int, or that its print
17628 length is less than 20.
17630 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17632 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17634 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17636 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17637 We prefer signed integers, even for size calculations.
17639 * emacs.c: Don't assume string length fits in 'int'.
17640 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17641 (main): Don't invoke strlen when not needed.
17643 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17644 (XD_DEBUG_MESSAGE): Don't waste a byte.
17646 * callproc.c (getenv_internal_1, getenv_internal)
17647 (Fgetenv_internal):
17648 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17650 * lread.c (invalid_syntax): Omit length argument.
17651 All uses changed. This doesn't fix a bug, but it simplifies the
17652 code away from its former Hollerith-constant appearance, and it's
17653 one less 'int' to worry about when looking at integer-overflow issues.
17654 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17656 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17657 This didn't break anything, but it didn't help either.
17658 It's confusing to put a bogus integer in a place where the actual
17659 value does not matter.
17660 (LIST_END_P): Remove unused macro and its bogus comment.
17661 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17663 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17664 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17666 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17667 We prefer signed types, and the value cannot exceed the EMACS_INT
17668 range anyway (because otherwise the length would not be representable).
17669 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17670 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17671 This avoids a GCC warning when WIDE_EMACS_INT.
17673 * indent.c (sane_tab_width): New function.
17674 (current_column, scan_for_column, Findent_to, position_indentation)
17675 (compute_motion): Use it. This is just for clarity.
17676 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17678 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17680 * lisp.h (lint_assume): New macro.
17681 * composite.c (composition_gstring_put_cache):
17682 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17684 * editfns.c, insdel.c:
17685 Omit unnecessary forward decls, to simplify future changes.
17687 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17689 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17691 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17692 Use much-faster test for byte-length change.
17693 Don't assume string byte-length fits in 'int'.
17694 Check that character arg fits in 'int'.
17695 (mapcar1): Declare byte as byte, for clarity.
17697 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17699 * fns.c (concat): Catch string overflow earlier.
17700 Do not rely on integer wraparound.
17702 * dispextern.h (struct it.overlay_strings_charpos)
17703 (struct it.selective): Now EMACS_INT, not int.
17704 * xdisp.c (forward_to_next_line_start)
17705 (back_to_previous_visible_line_start)
17706 (reseat_at_next_visible_line_start, next_element_from_buffer):
17707 Don't arbitrarily truncate the value of 'selective' to int.
17709 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17711 * composite.c: Don't truncate sizes to 'int'.
17712 (composition_gstring_p, composition_reseat_it)
17713 (composition_adjust_point): Use EMACS_INT, not int.
17714 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17715 not EMACS_UINT, for indexes.
17717 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17719 * buffer.c: Include <verify.h>.
17720 (struct sortvec.priority, struct sortstr.priority):
17721 Now EMACS_INT, not int.
17722 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17723 (struct sortstr.size, record_overlay_string)
17724 (struct sortstrlist.size, struct sortlist.used):
17725 Don't truncate size to int.
17726 (record_overlay_string): Check for size-calculation overflow.
17727 (init_buffer_once): Check at compile-time, not run-time.
17729 2011-06-22 Jim Meyering <meyering@redhat.com>
17731 Don't leak an XBM-image-sized buffer
17732 * image.c (xbm_load): Free the image buffer after using it.
17734 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17737 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17738 that Sun C diagnosed.
17739 * fns.c (secure_hash): Fix pointer signedness issue.
17740 * intervals.c (static_offset_intervals): New function.
17741 (offset_intervals): Use it.
17743 2011-06-21 Leo Liu <sdl.web@gmail.com>
17746 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17749 * fns.c (secure_hash): Rename from crypto_hash_function and change
17750 the first arg to accept symbols.
17751 (Fsecure_hash): New primitive.
17752 (syms_of_fns): New symbols.
17754 2011-06-20 Deniz Dogan <deniz@dogan.se>
17756 * process.c (Fset_process_buffer): Clarify return value in
17759 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17761 * dispnew.c (add_window_display_history): Use BVAR.
17763 * xdisp.c (debug_method_add): Use BVAR.
17764 (check_window_end, dump_glyph_matrix, dump_glyph)
17765 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17767 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17770 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17771 check till after the cache is created in init_frame_faces.
17773 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17775 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17777 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17779 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17780 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17781 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17783 Improve buffer-overflow checking (Bug#8873).
17784 * fileio.c (Finsert_file_contents):
17785 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17786 Remove the old (too-loose) buffer overflow checks.
17787 They weren't needed, since make_gap checks for buffer overflow.
17788 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17789 The old code merely checked for Emacs fixnum overflow, and relied
17790 on undefined (wraparound) behavior. The new code avoids undefined
17791 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17793 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17794 Tune. Don't use wider integers than needed. Don't use alloca.
17795 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17797 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17799 * insdel.c, lisp.h (buffer_overflow): New function.
17800 (insert_from_buffer_1, replace_range, replace_range_2):
17801 * insdel.c (make_gap_larger):
17802 * editfns.c (Finsert_char):
17803 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17805 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17807 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17809 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17811 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17812 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17814 * fileio.c: Don't assume EMACS_INT fits in off_t.
17815 (emacs_lseek): New static function.
17816 (Finsert_file_contents, Fwrite_region): Use it.
17817 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17819 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17821 * fns.c: Don't overflow int when computing a list length.
17822 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17823 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17824 truncation on 64-bit hosts. Check for QUIT every
17825 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17826 faster and is responsive enough.
17827 (Flength): Report an error instead of overflowing an integer.
17828 (Fsafe_length): Return a float if the value is not representable
17829 as a fixnum. This shouldn't happen except in contrived situations.
17830 (Fnthcdr, Fsort): Don't assume list length fits in int.
17831 (Fcopy_sequence): Don't assume vector length fits in int.
17833 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17834 (header_size, word_size): New constants.
17835 (allocate_vectorlike): Don't check size overflow here.
17836 (allocate_vector): Check it here instead, since this is the only
17837 caller of allocate_vectorlike that could cause overflow.
17838 Check that the new vector's length is representable as a fixnum.
17840 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17841 The previous code was bogus. For example, next_almost_prime (32)
17842 returned 39, which is undesirable as it is a multiple of 3; and
17843 next_almost_prime (24) returned 25, which is a multiple of 5 so
17844 why was the code bothering to check for multiples of 7?
17846 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17848 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17850 Variadic C functions now count arguments with ptrdiff_t.
17851 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17852 Back then I didn't know that the Emacs coding style prefers signed int.
17853 Also, in the meantime I found a few more instances where arguments
17854 were being counted with int, which may truncate counts on 64-bit
17855 machines, or EMACS_INT, which may be unnecessarily wide.
17856 * lisp.h (struct Lisp_Subr.function.aMANY)
17857 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17858 Arg counts are now ptrdiff_t, not size_t.
17859 All variadic functions and their callers changed accordingly.
17860 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17861 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17862 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17863 * callint.c (Fcall_interactively): Check arg count for overflow,
17864 to avoid potential buffer overrun. Use signed char, not 'int',
17865 for 'varies' array, so that we needn't bother to check its size
17866 calculation for overflow.
17867 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17868 * eval.c (apply_lambda):
17869 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17870 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17871 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17873 * callint.c (Fcall_interactively): Don't use index var as event count.
17875 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17876 * mem-limits.h (SIZE): Remove; no longer used.
17878 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17880 Remove unnecessary casts.
17881 * xterm.c (x_term_init):
17882 * xfns.c (x_set_border_pixel):
17883 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17884 These aren't needed now that we assume ANSI C.
17886 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17887 It's more likely to cause problems (due to unsigned overflow)
17890 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17892 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17894 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17896 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17898 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17900 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17902 GLYPH_CODE_FACE returns EMACS_INT, not int.
17903 * dispextern.h (merge_faces):
17904 * xfaces.c (merge_faces):
17905 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17906 Don't assume EMACS_INT fits in int.
17908 * character.h (CHAR_VALID_P): Remove unused parameter.
17909 * fontset.c, lisp.h, xdisp.c: All uses changed.
17911 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17913 * fns.c (concat): Minor tuning based on overflow analysis.
17914 This doesn't fix any bugs. Use int to hold character, instead
17915 of constantly refetching from Emacs object. Use XFASTINT, not
17916 XINT, for value known to be a character. Don't bother comparing
17917 a single byte to 0400, as it's always less.
17919 * floatfns.c (Fexpt):
17920 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17922 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17925 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17927 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17928 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17929 incorrectly succeed when S was a string, because 4294967386 was
17930 truncated before it was used.
17932 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17933 Otherwise, an out-of-range integer could cause undefined behavior
17936 * composite.c: Use int, not EMACS_INT, for characters.
17937 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17938 EMACS_INT, for values that are known to be in character range.
17939 This doesn't fix any bugs but is the usual style inside Emacs and
17940 may generate better code on 32-bit machines.
17942 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17943 This is for reasons similar to the recent CHAR_STRING fix.
17944 * charset.c (Fencode_char): Check that character arg is actually
17945 a character. Pass an int to ENCODE_CHAR.
17946 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17947 wider than 'int', as a compile-time check to prevent future regressions
17950 * character.c (char_string): Remove unnecessary casts.
17952 Make sure a 64-bit char is never passed to CHAR_STRING.
17953 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17954 by silently ignoring the top 32 bits, allowing some values
17955 that were far too large to be valid characters.
17956 * character.h: Include <verify.h>.
17957 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17958 arguments are no wider than unsigned, as a compile-time check
17959 to prevent future regressions in this area.
17961 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17962 (Fsubst_char_in_region):
17964 * xdisp.c (decode_mode_spec_coding):
17965 Adjust to CHAR_STRING's new requirement.
17966 * editfns.c (Finsert_char, Fsubst_char_in_region):
17967 * fns.c (concat): Check that character args are actually
17968 characters. Without this test, these functions did the wrong
17969 thing with wildly out-of-range values on 64-bit hosts.
17971 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17972 These casts should not be needed on 32-bit hosts, either.
17973 * keyboard.c (read_char):
17974 * lread.c (Fload): Remove casts to unsigned.
17976 * lisp.h (UNSIGNED_CMP): New macro.
17977 This fixes comparison bugs on 64-bit hosts.
17978 (ASCII_CHAR_P): Use it.
17979 * casefiddle.c (casify_object):
17980 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17981 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17982 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17983 * dispextern.h (FACE_FROM_ID):
17984 * keyboard.c (read_char): Use UNSIGNED_CMP.
17986 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17987 not to EMACS_INT, to avoid GCC warning.
17989 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17991 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17992 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17993 isn't needed on 32-bit machines.
17995 * buffer.c (Fgenerate_new_buffer_name):
17996 Use EMACS_INT for count, not int.
17997 (advance_to_char_boundary): Return EMACS_INT, not int.
17999 * data.c (Qcompiled_function): Now static.
18001 * window.c (window_body_lines): Now static.
18003 * image.c (gif_load): Rename local to avoid shadowing.
18005 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18006 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18007 * alloc.c (make_save_value): Integer argument is now of type
18008 ptrdiff_t, not int.
18009 (mark_object): Use ptrdiff_t, not int.
18010 * lisp.h (pD): New macro.
18011 * print.c (print_object): Use it.
18013 * alloc.c: Use EMACS_INT, not int, to count objects.
18014 (total_conses, total_markers, total_symbols, total_vector_size)
18015 (total_free_conses, total_free_markers, total_free_symbols)
18016 (total_free_floats, total_floats, total_free_intervals)
18017 (total_intervals, total_strings, total_free_strings):
18018 Now EMACS_INT, not int. All uses changed.
18019 (Fgarbage_collect): Compute overall total using a double, so that
18020 integer overflow is less likely to be a problem. Check for overflow
18021 when converting back to an integer.
18022 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18023 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18024 These were 'int' variables that could overflow on 64-bit hosts;
18025 they were never used, so remove them instead of repairing them.
18026 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18027 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18028 Previously, this ceilinged at INT_MAX, but that doesn't work on
18030 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18032 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18033 (allocate_vectorlike): Check for ptrdiff_t overflow.
18034 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18035 when a (possibly-narrower) signed value would do just as well.
18036 We prefer using signed arithmetic, to avoid comparison confusion.
18038 * alloc.c: Catch some string size overflows that we were missing.
18039 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18040 for convenience in STRING_BYTES_MAX.
18041 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18042 The definition here is exact; the one in lisp.h was approximate.
18043 (allocate_string_data): Check for string overflow. This catches
18044 some instances we weren't catching before. Also, it catches
18045 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18046 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18047 and ptrdiff_t and EMACS_INT are both 64 bits.
18049 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18050 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18051 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18053 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18055 * alloc.c (Fmake_string): Check for out-of-range init.
18057 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18059 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18061 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18063 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18064 xg_get_default_scrollbar_width.
18066 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18067 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18068 (style_changed_cb): Call update_theme_scrollbar_width and call
18069 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18070 all frames (Bug#8505).
18071 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18072 Call gtk_window_set_resizable if HAVE_GTK3.
18073 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18074 and height if HAVE_GTK3 (Bug#8505).
18075 (scroll_bar_width_for_theme): New variable.
18076 (update_theme_scrollbar_width): New function.
18077 (xg_get_default_scrollbar_width): Move code to
18078 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18079 (xg_initialize): Call update_theme_scrollbar_width.
18081 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18083 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18085 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18087 * frame.c (make_frame): Call other_buffer_safely instead of
18090 * window.c (temp_output_buffer_show): Call display_buffer with
18091 second argument Vtemp_buffer_show_specifiers and reset latter
18092 immediately after the call.
18093 (Vtemp_buffer_show_specifiers): New variable.
18094 (auto_window_vscroll_p, next_screen_context_lines)
18095 (Vscroll_preserve_screen_position): Remove leading asterisks from
18098 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18100 Fix minor problems found by GCC 4.6.0 static checking.
18101 * buffer.c (Qclone_number): Remove for now, as it's unused.
18102 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18103 (record_buffer): Remove unused local.
18104 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18105 (set_frame_buffer_list): Remove; unused.
18106 * frame.h (other_visible_frames): Remove decl.
18107 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18108 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18109 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18111 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18112 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18113 Define only if HAVE_GPM.
18114 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18115 (update_hints_inhibit): Remove; never set. All uses removed.
18116 * widgetprv.h (emacsFrameClassRec): Remove decl.
18117 * window.c (delete_deletable_window): Now returns void, since it
18118 wasn't returning anything.
18119 (compare_window_configurations): Remove unused locals.
18120 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18121 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18122 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18123 the same widths as pointers. This follows up on the 2011-05-06 patch.
18124 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18125 * xterm.h: Likewise.
18126 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

18131 (LISP_H): Add lib/intprops.h.
18133 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18135 * image.c (gif_load): Add animation frame delay to the metadata.
18136 (syms_of_image): Use DEFSYM. New symbol `delay'.
18138 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18140 * window.c (delete_deletable_window): Re-add.
18141 (Fset_window_configuration): Rewrite to handle dead buffers and
18142 consequently deletable windows.
18143 (window_tree, Fwindow_tree): Remove. Supply functionality in
18145 (compare_window_configurations): Simplify code.
18147 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18149 * image.c (imagemagick_load_image): Fix type mismatch.
18150 (Fimagemagick_types): Likewise.
18152 * window.h (replace_buffer_in_windows): Declare.
18154 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18156 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18157 Qclone_number. Remove external declaration of Qdelete_window.
18158 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18160 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18161 Run Qbuffer_list_update_hook if allowed.
18162 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18163 buffer list implementation.
18164 (other_buffer_safely): New function.
18165 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18166 calls to replace_buffer_in_windows and
18167 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18169 (record_buffer): Inhibit quitting and rewrite using quittable
18170 functions. Run Qbuffer_list_update_hook if allowed.
18171 (Frecord_buffer, Funrecord_buffer): New functions.
18172 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18173 Move switch-to-buffer to window.el.
18174 (bury-buffer): Move to window.el.
18175 (Vbuffer_list_update_hook): New variable.
18177 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18180 * window.h (resize_frame_windows): Move up in code.
18181 (Fwindow_frame): Remove EXFUN.
18182 (replace_buffer_in_all_windows): Remove prototype.
18183 (replace_buffer_in_windows_safely): Add prototype.
18185 * window.c: Declare Qdelete_window static again. Move down
18186 declaration of select_count.
18187 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18188 (Fother_window): Move to window.el.
18189 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18190 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18191 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18193 (replace_buffer_in_windows): Implement by calling
18194 Qreplace_buffer_in_windows.
18195 (replace_buffer_in_all_windows): Remove with some functionality
18196 moved into replace_buffer_in_windows_safely.
18197 (replace_buffer_in_windows_safely): New function.
18198 (select_window_norecord, select_frame_norecord): Move in front
18199 of run_window_configuration_change_hook. Remove now obsolete
18201 (Fset_window_buffer): Rewrite doc-string.
18202 Call Qrecord_window_buffer.
18203 (keys_of_window): Move binding for other-window to window.el.
18205 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18207 * dispextern.h (struct image): Replace data member, whose int_val
18208 and ptr_val fields were not used by anything, with a single
18211 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18212 (gif_clear_image, gif_load, imagemagick_load_image)
18213 (gs_clear_image, gs_load): Callers changed.

18678 (compute_display_string_pos, compute_display_string_end):
18679 Declare prototypes.
18680 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18683 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18685 Malloc failure behavior now depends on size of allocation.
18686 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18687 * lisp.h: Change signatures accordingly.
18688 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18689 All callers changed. (Bug#8762)
18691 * gnutls.c: Use Emacs's memory allocators.
18692 Without this change, the gnutls library would invoke malloc etc.
18693 directly, which causes problems on non-SYNC_INPUT hosts, and which
18694 runs afoul of improving memory_full behavior. (Bug#8761)
18695 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18696 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18697 xfree instead of the default malloc, realloc, free.
18698 (Fgnutls_boot): No need to check for memory allocation failure,
18699 since xmalloc does that for us.
18701 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18702 * category.c (hash_get_category_set):
18703 * ccl.c (ccl_driver):
18704 * charset.c (Fdefine_charset_internal):
18705 * charset.h (struct charset.hash_index):

18707 (composition_gstring_put_cache):
18708 * composite.h (struct composition.hash_index):
18709 * dispextern.h (struct image.hash):

18715 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18716 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18717 * image.c (make_image, search_image_cache, lookup_image)
18718 (xpm_put_color_table_h):
18719 * lisp.h (struct Lisp_Hash_Table):
18720 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18721 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18722 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18723 * alloc.c (allocate_vectorlike):
18724 Check for overflow in vector size calculations.
18725 * ccl.c (ccl_driver):
18726 Check for overflow when converting EMACS_INT to int.
18727 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18728 need to be updated by these changes.
18729 * fns.c (make_hash_table, maybe_resize_hash_table):
18730 Check for integer overflow with large hash tables.
18731 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18732 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18733 (SXHASH_REDUCE): New macro.
18734 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18735 Use it instead of discarding useful hash info with large hash values.
18736 (sxhash_float): New function.
18737 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18738 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18739 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18740 Rewrite to use FIXNUM_BITS, as this simplifies things.
18741 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18742 Adjust signatures to match updated version of code.
18743 (consing_since_gc): Now EMACS_INT, since a single hash table can
18744 use more than INT_MAX bytes.
18746 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18748 Make it possible to build with GCC-4.6+ -O2 -flto.
18750 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18752 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18754 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18755 Call minibuffer-inactive-mode.
18757 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18759 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18760 Update dependencies.
18762 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18764 * data.c (init_data): Remove code for UTS, this system is not
18767 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18769 Don't force ./temacs to start in terminal mode.
18771 * frame.c (make_initial_frame): Initialize faces in all cases, not
18772 only when CANNOT_DUMP is defined.
18773 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18775 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18777 * dispnew.c (add_window_display_history): Use const for the string
18778 pointer. Remove declaration, not needed.
18780 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18782 Use 'inline', not 'INLINE'.
18783 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18784 * alloc.c, fontset.c (INLINE): Remove.
18785 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18786 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18787 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18788 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18789 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18791 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18793 Make it possible to run ./temacs.
18795 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18796 syms_of_callproc does the same thing. Remove test for
18797 "initialized", do it in the caller.
18798 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18800 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18802 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18803 (read_minibuf): Use get_minibuffer.
18804 (syms_of_minibuf): Use DEFSYM.
18805 (Qmetadata): New var.
18806 * data.c (Qbuffer): Don't make it static.
18807 (syms_of_data): Use DEFSYM.
18809 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18811 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18812 (CCL_CODE_MIN): New macro.
18814 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18816 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18818 * eval.c (Qdebug): Now static.
18819 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18820 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18821 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18823 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18825 * image.c: Various fixes to ImageMagick code comments.
18826 (Fimagemagick_types): Doc fix.
18828 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18830 Minor fixes prompted by GCC 4.6.0 warnings.
18832 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18834 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18835 (x_clipboard_manager_save_all): Move extern decl to ...
18836 * xterm.h: ... here, so that it can be checked for consistency.
18838 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18840 * xselect.c (x_clipboard_manager_save_frame)
18841 (x_clipboard_manager_save_all): New functions.
18842 (Fx_clipboard_manager_save): Lisp function deleted.
18844 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18845 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18847 * xterm.h: Update prototype.
18849 2011-05-28 William Xu <william.xwl@gmail.com>
18851 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18852 exiting (Bug#8239).
18854 2011-05-28 Jim Meyering <meyering@redhat.com>
18856 Avoid a sign-extension bug in crypto_hash_function.
18857 * fns.c (to_uchar): Define.
18858 (crypto_hash_function): Use it to convert some newly-signed
18859 variables to unsigned, to avoid sign-extension bugs. For example,
18860 without this change, (md5 "truc") would evaluate to
18861 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18862 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18863 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18865 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18867 Integer overflow fixes.
18869 * dbusbind.c: Serial number integer overflow fixes.
18870 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18871 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18872 to hold a serial number that is too large for a fixnum.
18873 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18874 Check for serial numbers out of range. Decode any serial number
18875 that was so large that it became a float. (Bug#8722)
18877 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18878 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18879 Use XFASTINT rather than XUINT when numbers are nonnegative.
18880 (xd_append_arg, Fdbus_method_return_internal):
18881 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18882 arguments, check that Lisp number is nonnegative, rather than
18883 silently wrapping negative numbers around. (Bug#8722)
18884 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18887 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18889 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18891 ccl: Add integer overflow checks.
18892 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18893 (IN_INT_RANGE): New macros.
18894 (ccl_driver): Use them to check for integer overflow when
18895 decoding a CCL program. Many of the new checks are whether XINT (x)
18896 fits in int; it doesn't always, on 64-bit hosts. The new version
18897 doesn't catch all possible integer overflows, but it's an
18898 improvement. (Bug#8719)
18900 * alloc.c (make_event_array): Use XINT, not XUINT.
18901 There's no need for unsigned here.
18903 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18904 This follows up to the 2011-05-06 change that substituted uintptr_t
18905 for EMACS_INT. This case wasn't caught back then.
18907 Rework Fformat to avoid integer overflow issues.
18908 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18909 now (part of C89). Include <verify.h>.
18910 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18911 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18912 (Fformat): Avoid the prepass trying to compute sizes; it was only
18913 approximate and thus did not catch overflow reliably. Instead, walk
18914 through the format just once, formatting and computing sizes as we go,
18915 checking for integer overflow at every step, and allocating a larger
18916 buffer as needed. Keep track separately whether the format is
18917 multibyte. Keep only the most-recently calculated precision, rather
18918 than them all. Record whether each argument has been converted to
18919 string. Use EMACS_INT, not int, for byte and char and arg counts.
18920 Support field widths and precisions larger than INT_MAX. Avoid
18921 sprintf's undefined behavior with conversion specifications such as %#d
18922 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18923 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18924 formatting out-of-range floating point numbers with int
18925 formats. (Bug#8668)
18927 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18929 * data.c: Avoid integer truncation in expressions involving floats.
18930 * data.c: Include <intprops.h>.
18931 (arith_driver): When there's an integer overflow in an expression
18932 involving floating point, convert the integers to floating point
18933 so that the resulting value does not suffer from catastrophic
18934 integer truncation. For example, on a 64-bit host (* 4
18935 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18936 Do not rely on undefined behavior after integer overflow.
18938 merge count_size_as_multibyte, parse_str_to_multibyte
18939 * character.c, character.h (count_size_as_multibyte):
18940 Rename from parse_str_to_multibyte; all uses changed.
18941 Check for integer overflow.
18942 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18943 since it's now a duplicate of the other. This is more of
18944 a character than a buffer op, so better that it's in character.c.
18945 * fns.c, print.c: Adjust to above changes.
18947 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18949 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18951 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18953 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18954 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18955 (x_clipboard_manager_save): Now static.
18956 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18958 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18959 (crypto_hash_function): Now static.
18960 Fix pointer signedness problems. Avoid unnecessary initializations.
18962 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18964 * termhooks.h (Vselection_alist): Make it terminal-local.
18966 * terminal.c (create_terminal): Initialize it.
18968 * xselect.c: Support for clipboard managers.
18969 (Vselection_alist): Move to termhooks.h as terminal-local var.
18970 (LOCAL_SELECTION): New macro.
18971 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18972 (symbol_to_x_atom): Remove gratuitous arg.
18973 (x_handle_selection_request, lisp_data_to_selection_data)
18974 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18975 (x_own_selection, x_get_local_selection, x_convert_selection):
18976 New arg, specifying work frame. Use terminal-local Vselection_alist.
18977 (some_frame_on_display): Delete unused function.
18978 (Fx_own_selection_internal, Fx_get_selection_internal)
18979 (Fx_disown_selection_internal, Fx_selection_owner_p)
18980 (Fx_selection_exists_p): New optional frame arg.
18981 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18982 (x_handle_selection_clear): Don't treat other terminals with the
18983 same keyboard specially. Use the terminal-local Vselection_alist.
18984 (x_clear_frame_selections): Use Frun_hook_with_args.
18986 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18988 * xterm.h: Add support for those atoms.
18990 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18992 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18993 (converted_selections, conversion_fail_tag): New global variables.
18994 (x_selection_request_lisp_error): Free the above.
18995 (x_get_local_selection): Remove unnecessary code.
18996 (x_reply_selection_request): Args changed; handle arbitrary array
18997 of converted selections stored in converted_selections.
18998 Separate the XChangeProperty and SelectionNotify steps.
18999 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19000 (x_convert_selection): New function.
19001 (x_handle_selection_event): Simplify.
19002 (x_get_foreign_selection): Don't ignore incoming requests while
19003 waiting for an answer; this will fail when we implement
19004 SAVE_TARGETS, and seems unnecessary anyway.
19005 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19006 (Vx_sent_selection_functions): Doc fix.
19008 2011-05-26 Leo Liu <sdl.web@gmail.com>
19010 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19012 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19014 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19016 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19017 for fringe update if it has periodic bitmap.
19018 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19019 and fringe_bitmap_periodic_p.
19021 * fringe.c (get_fringe_bitmap_data): New function.
19022 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19023 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19024 row. Mark glyph row for fringe update if periodicity changed.
19026 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19027 for fringe update unless it has periodic bitmap.
19029 2011-05-25 Kenichi Handa <handa@m17n.org>
19031 * xdisp.c (get_next_display_element): Set correct it->face_id for

19047 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19048 Remove macros that are defined and never used.
19049 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19051 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19053 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19054 (Fx_get_selection_internal): Minor cleanup.

19080 report_file_error introduced by the change from 2011-05-07.
19082 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19084 * systime.h (Time): Define only if emacs is defined.
19085 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19086 where the include path doesn't have X11/X.h by default. See
19087 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19089 2011-05-20 Kenichi Handa <handa@m17n.org>
19091 * composite.c (find_automatic_composition): Fix previous change.
19093 2011-05-20 Glenn Morris <rgm@gnu.org>

19106 (shortlisp): Make it a copy of $lisp.
19107 (SOME_MACHINE_LISP): Remove.
19108 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19109 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19111 2011-05-18 Kenichi Handa <handa@m17n.org>
19113 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19114 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19115 (find_automatic_composition): Mostly rewrite for efficiency.
19117 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19119 * makefile.w32-in: Update dependencies.
19121 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19123 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19124 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19126 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19128 Fix some integer overflow issues, such as string length overflow.
19130 * insdel.c (count_size_as_multibyte): Check for string overflow.
19132 * character.c (lisp_string_width): Check for string overflow.
19133 Use EMACS_INT, not int, for string indexes and lengths; in
19134 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19135 the resulting string length overflows an EMACS_INT; instead,
19136 report a string overflow if no precision given. When checking for
19137 precision exhaustion, use a check that cannot possibly have
19138 integer overflow. (Bug#8675)
19139 * character.h (lisp_string_width): Adjust to new signature.
19141 * alloc.c (string_overflow): New function.
19142 (Fmake_string): Use it. This doesn't change behavior, but saves
19143 a few bytes and will simplify future changes.
19144 * character.c (string_escape_byte8): Likewise.
19145 * lisp.h (string_overflow): New decl.
19147 Fixups, following up to the user-interface timestamp change.
19148 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19149 for UI timestamps, instead of unsigned long.
19150 * msdos.c (mouse_get_pos): Likewise.
19151 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19152 * w32gui.h (Time): Define by including "systime.h" rather than by
19153 declaring it ourselves. (Bug#8664)
19155 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19156 * image.c (clear_image_cache): Likewise.
19158 * term.c (term_mouse_position): Don't assume time_t wraparound.
19160 Be more systematic about user-interface timestamps.
19161 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19162 and sometimes 'EMACS_UINT', to represent these timestamps.
19163 This change causes it to use 'Time' uniformly, as that's what X uses.
19164 This makes the code easier to follow, and makes it easier to catch
19165 integer overflow bugs such as Bug#8664.
19166 * frame.c (Fmouse_position, Fmouse_pixel_position):
19167 Use Time, not unsigned long, for user-interface timestamps.
19168 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19169 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19170 * keyboard.h (last_event_timestamp): Likewise.
19171 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19172 * menu.h (xmenu_show): Likewise.
19173 * term.c (term_mouse_position): Likewise.
19174 * termhooks.h (struct input_event.timestamp): Likewise.
19175 (struct terminal.mouse_position_hook): Likewise.
19176 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19177 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19178 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19179 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19180 what it was before.
19181 * menu.h, termhooks.h: Include "systime.h", for Time.
19183 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19184 Don't assume that the difference between two unsigned long values
19185 can fit into an integer. At this point, we know button_down_time
19186 <= event->timestamp, so the difference must be nonnegative, so
19187 there's no need to cast the result if double-click-time is
19188 nonnegative, as it should be; check that it's nonnegative, just in
19189 case. This bug is triggered when events are more than 2**31 ms
19190 apart (about 25 days). (Bug#8664)
19192 * xselect.c (last_event_timestamp): Remove duplicate decl.
19193 (x_own_selection): Remove needless cast to unsigned long.
19195 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19196 that always fit in int. Use a sentinel instead of a counter, to
19197 avoid a temp and to allay GCC's concerns about possible int overflow.
19198 * frame.h (struct frame): Use int for menu_bar_items_used
19199 instead of EMACS_INT, since it always fits in int.
19201 * menu.c (grow_menu_items): Check for int overflow.
19203 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19205 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19206 Before, the code was not consistent. These values cannot exceed
19207 2**31 - 1 so there's no need to make them unsigned.
19208 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19209 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19210 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19212 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19214 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19215 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19216 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19217 presumably because the widths might not match.
19219 * window.c (size_window): Avoid needless test at loop start.
19221 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19223 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19225 2011-05-12 Drew Adams <drew.adams@oracle.com>
19227 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19229 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19231 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19232 `width' to `bar_area_x' and `bar_area_width', respectively.
19233 (x_scroll_run): Take account of fringe background extension.
19235 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19236 Rename local vars `left' and `width' to `bar_area_x' and
19237 `bar_area_width', respectively.
19238 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19239 background extension.
19241 2011-05-10 Jim Meyering <meyering@redhat.com>
19243 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19245 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19247 * image.c (Finit_image_library): Return t for built-in image types,
19248 like pbm and xbm. (Bug#8640)
19250 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19252 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19254 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19256 * w32console.c (Fset_screen_color): Doc fix.
19257 (Fget_screen_color): New function.
19258 (syms_of_ntterm): Defsubr it.
19260 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19261 unlink the temporary file if Fcall_process didn't create it in the
19263 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19264 child process will be redirected to a file specified with `:file'.
19265 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19266 cue to call_process_cleanup not to close that handle.
19268 2011-05-07 Ben Key <bkey76@gmail.com>
19270 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19271 one of two shell specific rules, either bootstrap-temacs-CMD or
19272 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19273 to the previous implementation of the bootstrap-temacs rule.
19274 The bootstrap-temacs-CMD rule is similar to the previous
19275 implementation of the bootstrap-temacs rule except that it
19276 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19279 These changes, along with some changes to nt/configure.bat,
19280 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19281 earlier fix to add support for --cflags and --ldflags options
19282 that include quotes so that it works whether make uses cmd or
19285 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19287 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19288 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19290 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19291 a string. Handle both cases.
19292 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19293 (Fdbus_register_method): Use Qinvalid_function.
19295 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19297 * makefile.w32-in: Update dependencies.
19298 (LISP_H): Add inttypes.h and stdin.h.
19299 (PROCESS_H): Add unistd.h.
19301 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19303 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19304 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19306 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19308 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19310 * term.c (vfatal): Remove stray call to va_end.
19311 It's not needed and the C Standard doesn't allow it here anyway.
19313 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19314 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19316 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19319 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19321 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19323 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19325 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19327 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19329 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19330 * charset.c (Fdefine_charset_internal): Don't initialize
19331 charset.code_space[15]. The value was garbage, on hosts with
19332 32-bit int (Bug#8600).
19334 * lread.c (read_integer): Be more consistent with string-to-number.
19335 Use string_to_number to do the actual conversion; this avoids
19336 rounding errors and fixes some other screwups. Without this fix,
19337 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19338 (digit_to_number): Move earlier, for benefit of read_integer.
19339 Return -1 if the digit is out of range for the base, -2 if it is
19340 not a digit in any supported base. (Bug#8602)
19342 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19344 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19345 to match comment at start of function. This also removes a
19346 GCC warning about overflow in a 32+64-bit port.
19348 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19350 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19351 Reported by Stefan Monnier in
19352 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19353 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19354 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19356 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19357 (EMACS_UINTPTR): Likewise, with uintptr_t.
19359 * lisp.h: Prefer 64-bit EMACS_INT if available.
19360 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19361 on 32-bit hosts that have 64-bit int, so that they can access
19363 However, temporarily disable this change unless the temporary
19364 symbol WIDE_EMACS_INT is defined.
19366 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19368 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19369 This removes an assumption that EMACS_INT and long are the same
19370 width as pointers. The assumption is true for Emacs porting targets
19371 now, but we want to make other targets possible.
19372 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19373 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19374 In the rest of the code, change types of integers that hold casted
19375 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19376 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19377 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19378 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19379 No need to cast type when ORing.
19380 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19381 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19382 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19383 assume EMACS_INT is the same width as char *.
19384 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19385 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19386 Remove no-longer-needed casts.
19387 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19388 (xg_tool_bar_help_callback, xg_make_tool_item):
19389 Use EMACS_INTPTR to hold an integer
19390 that will be cast to void *; this can avoid a GCC warning
19391 if EMACS_INT is not the same width as void *.
19392 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19393 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19394 (current_message_1, set_message_1):
19395 Use a local to convert to proper width without a cast.
19396 * xmenu.c (dialog_selection_callback): Likewise.
19398 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19399 Also, don't assume VALBITS / RAND_BITS is less than 5,
19400 and don't rely on undefined behavior when shifting a 1 left into
19402 * lisp.h (get_random): Change signature to match.
19404 * lread.c (hash_string): Use size_t, not int, for hash computation.
19405 Normally we prefer signed values; but hashing is special, because
19406 it's better to use unsigned division on hash table sizes so that
19407 the remainder is nonnegative. Also, size_t is the natural width
19408 for hashing into memory. The previous code used 'int', which doesn't
19409 retain enough info to hash well into very large tables.
19410 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19412 * dbusbind.c: Don't possibly lose pointer info when converting.
19413 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19414 Use XPNTR rather than XHASH, so that the high-order bits of
19415 the pointer aren't lost when converting through void *.
19417 * eval.c (Fautoload): Don't double-shift a pointer.
19419 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19421 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19423 * gnutls.c (DEF_GNUTLS_FN):
19424 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19426 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19428 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19431 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19433 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19434 New version that can reserve upto 2GB of heap space.
19436 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19438 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19440 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19442 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19443 `gnutls_certificate_set_x509_key_file'.
19445 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19447 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19448 Update dependencies.
19450 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19452 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19453 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19454 Remove unused parameter `fildes'.
19455 * process.c (read_process_output, send_process): Don't pass it.
19457 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19459 Fix previous change: the library cache is defined in w32.c.
19460 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19461 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19463 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19465 Implement dynamic loading of GnuTLS on Windows.
19467 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19468 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19469 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19472 * gnutls.c (Qgnutls_dll): Define.
19473 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19474 (gnutls_*): Declare function pointers.
19475 (init_gnutls_functions): New function to initialize function pointers.
19476 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19477 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19478 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19479 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19480 (emacs_gnutls_write, emacs_gnutls_read)
19481 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19482 (Fgnutls_available_p): New function.
19483 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19484 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19485 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19487 * image.c: Include w32.h.
19488 (Vimage_type_cache): Delete.
19489 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19490 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19491 (w32_delayed_load): Move to w32.c.
19493 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19495 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19496 (w32_delayed_load): Move from image.c. When loading a library, record
19497 its filename in the :loaded-from property of the library id.
19498 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19499 Initialize and staticpro them.
19500 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19502 * process.c: Include lisp.h before w32.h, not after.
19503 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19504 instead of gnutls_record_check_pending.
19506 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19508 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19510 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19511 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19514 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19516 * xterm.c (x_set_frame_alpha): Do not set property on anything
19517 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19519 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19521 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19523 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19525 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19526 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19556 rather than `XVECTOR (FOO)->size'.
19558 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19559 inttypes.h, as a gnulib replacement is used if it not available in

19576 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19578 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of

19581 %llo or %llx format is passed. (Bug#8545)
19583 * window.c (window_scroll_line_based): Use a marker instead of
19584 simple variables to record original value of point. (Bug#7952)

19587 produced by %s or %c overflows available buffer space. (Bug#8545)
19589 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19591 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19603 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19604 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19606 2011-04-28 Eli Zaretskii <eliz@gnu.org>

19620 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19622 * makefile.w32-in: Update dependencies.
19624 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19626 Improve `doprnt' and its usage. (Bug#8545)
19627 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19628 `format_end'. Remove support for %l as a conversion specifier.
19629 Don't use xrealloc. Improve diagnostics when the %l size modifier
19630 is used. Update the commentary.
19632 * eval.c (verror): Simplify calculation of size_t.
19634 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19637 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19639 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19642 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19644 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19645 This makes this file independent of the recent pseudovector change.
19647 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19649 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19651 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19652 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19653 Remove unused local.
19654 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19656 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19657 GCC 4.6.0 optimizes based on type-based alias analysis.
19658 For example, if b is of type struct buffer * and v of type struct
19659 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19660 != &v->size, and therefore "v->size = 1; b->size = 2; return
19661 v->size;" must therefore return 1. This assumption is incorrect
19662 for Emacs, since it type-puns struct Lisp_Vector * with many other
19663 types. To fix this problem, this patch adds a new type struct
19664 vectorlike_header that documents the constraints on layout of vectors
19665 and pseudovectors, and helps optimizing compilers not get fooled
19666 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19667 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19668 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19670 (XSETPVECTYPE): Rewrite in terms of new macro.
19671 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19672 This is a bit clearer, and further avoids the possibility of
19673 undesirable aliasing.
19674 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19675 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19676 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19677 since Lisp_Subr is a special case (no "next" field).
19678 (ASIZE): Now uses header.size rather than size.
19679 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19680 to avoid the hassle of writing XVECTOR (foo)->header.size.
19681 (struct vectorlike_header): New type.
19682 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19683 object, to help avoid aliasing.
19684 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19685 (SUBRP): Likewise, since Lisp_Subr is a special case.
19686 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19687 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19688 (struct Lisp_Hash_Table): Combine first two members into a single
19689 struct vectorlike_header member. All uses of "size" and "next" members
19690 changed to be "header.size" and "header.next".
19691 * buffer.h (struct buffer): Likewise.
19692 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19693 * frame.h (struct frame): Likewise.
19694 * process.h (struct Lisp_Process): Likewise.
19695 * termhooks.h (struct terminal): Likewise.
19696 * window.c (struct save_window_data, struct saved_window): Likewise.
19697 * window.h (struct window): Likewise.
19698 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19699 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19700 * buffer.c (init_buffer_once): Likewise.
19701 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19703 * process.c (Fformat_network_address): Use local var for size,
19706 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19708 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19709 * data.c (atof): Remove decl; no longer used or needed.
19710 (digit_to_number): Move to lread.c.
19711 (Fstring_to_number): Use new string_to_number function, to be
19712 consistent with how the Lisp reader treats infinities and NaNs.
19713 Do not assume that floating-point numbers represent EMACS_INT
19714 without losing information; this is not true on most 64-bit hosts.
19715 Avoid double-rounding errors, by insisting on integers when
19716 parsing non-base-10 numbers, as the documentation specifies.
19717 * lisp.h (string_to_number): New decl, replacing ...
19718 (isfloat_string): Remove.
19719 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19720 (read1): Do not accept +. and -. as integers; this
19721 appears to have been a coding error. Similarly, do not accept
19722 strings like +-1e0 as floating point numbers. Do not report
19723 overflow for integer overflows unless the base is not 10 which
19724 means we have no simple and reliable way to continue.
19725 Break out the floating-point parsing into a new
19726 function string_to_number, so that Fstring_to_number parses
19727 floating point numbers consistently with the Lisp reader.
19728 (digit_to_number): Move here from data.c. Make it static inline.
19729 (E_CHAR, EXP_INT): Remove, replacing with ...
19730 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19731 (string_to_number): New function, replacing isfloat_string.
19732 This function checks for valid syntax and produces the resulting
19733 Lisp float number too. Rework it so that string-to-number
19734 no longer mishandles examples like "1.0e+". Use strtoumax,
19735 so that overflow for non-base-10 numbers is reported only when
19736 there's no portable and simple way to convert to floating point.
19738 * textprop.c (set_text_properties_1): Rewrite for clarity,
19739 and to avoid GCC warning about integer overflow.
19741 * intervals.h (struct interval): Use EMACS_INT for members
19742 where EMACS_UINT might cause problems. See
19743 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19744 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19745 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19747 (offset_intervals): Tell GCC not to worry about length overflow
19748 when negating a negative length.
19750 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19751 (overrun_check_free): Likewise.
19753 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19754 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19757 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19758 (gnutls_make_error): Rename local to avoid shadowing.
19759 (gnutls_emacs_global_deinit): ifdef out; not used.
19760 (Fgnutls_boot): Use const for pointer to readonly storage.
19761 Comment out unused local. Fix pointer signedness problems.
19763 * lread.c (openp): Don't stuff size_t into an 'int'.
19764 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19765 about possible signed overflow.
19767 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19768 (GDK_KEY_g): Don't define if already defined.
19769 (xg_prepare_tooltip): Avoid pointer signedness problem.
19770 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19772 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19773 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19775 * xfns.c (Fx_window_property): Simplify a bit,
19776 to make a bit faster and to avoid GCC 4.6.0 warning.
19777 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19779 * fns.c (internal_equal): Don't assume size_t fits in int.
19781 * alloc.c (compact_small_strings): Tighten assertion a little.
19783 Replace pEd with more-general pI, and fix some printf arg casts.
19784 * lisp.h (pI): New macro, generalizing old pEd macro to other
19785 conversion specifiers. For example, use "...%"pI"d..." rather
19786 than "...%"pEd"...".
19787 (pEd): Remove. All uses replaced with similar uses of pI.
19788 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19789 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19790 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19791 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19792 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19793 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19794 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19796 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19797 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19798 * print.c (safe_debug_print, print_object): Likewise.
19799 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19801 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19802 avoiding the 0 flag, which is not portable.
19803 * process.c (Fmake_network_process): Use pI to avoid cast.
19804 * region-cache.c (pp_cache): Likewise.
19805 * xdisp.c (decode_mode_spec): Likewise.
19806 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19807 behavior on 64-bit hosts with printf arg.
19808 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19809 (x_stop_queuing_selection_requests): Likewise.
19810 (x_get_window_property): Don't truncate byte count to an 'int'
19813 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19814 here, since it parses constructs like leading '-' and spaces,
19815 which are not wanted; and it overflows with large numbers.
19816 Instead, simply match F[0-9]+, which is what is wanted anyway.
19818 * alloc.c: Remove unportable assumptions about struct layout.
19819 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19820 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19821 (allocate_vectorlike, make_pure_vector): Use the new macros,
19822 plus offsetof, to remove unportable assumptions about struct layout.
19823 These assumptions hold on all porting targets that I know of, but
19824 they are not guaranteed, they're easy to remove, and removing them
19825 makes further changes easier.
19827 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19828 This doesn't fix a bug but makes the code clearer.
19829 (string_overrun_cookie): Now const. Use initializers that
19830 don't formally overflow signed char, to avoid warnings.
19831 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19832 can cause Emacs to crash when string overrun checking is enabled.
19833 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19834 multiple of sizeof (EMACS_INT); it need not be, if
19835 alignof(EMACS_INT) < sizeof (EMACS_INT).
19836 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19838 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19845 supposed to be handshaking. (Bug#8556)
19846 Reported by Paul Eggert <eggert@cs.ucla.edu>.

19853 (handle_user_signal): Break into debugger when debug-on-event
19854 matches the current signal symbol.
19856 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19858 * alloc.c (check_sblock, check_string_bytes)
19859 (check_string_free_list): Convert to standard C.
19861 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19863 * w32.c (emacs_gnutls_push): Fix typo.
19865 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19867 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19868 "cast to pointer from integer of different size".
19870 Improve doprnt and its use in verror. (Bug#8545)
19871 * doprnt.c (doprnt): Document the set of format control sequences
19872 supported by the function. Use SAFE_ALLOCA instead of always
19875 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19876 is one byte too soon. Don't use xrealloc; instead xfree and
19879 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19881 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19884 * gnutls.c: Renamed global_initialized to
19885 gnutls_global_initialized. Added internals for the
19886 :verify-hostname-error, :verify-error, and :verify-flags
19887 parameters of `gnutls-boot' and documented those parameters in the
19888 docstring. Start callback support.
19889 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19890 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19891 on error. Return error code.
19892 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19893 (emacs_gnutls_read): Likewise.
19894 (Fgnutls_boot): Return handshake error code.
19895 (emacs_gnutls_handle_error): New function.
19896 (wsaerror_to_errno): Likewise.

19901 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
19902 (emacs_gnutls_push): Likewise.
19904 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19906 * process.c (wait_reading_process_output): Check if GnuTLS
19907 buffered some data internally if no FDs are set for TLS
19910 * makefile.w32-in (OBJ2): Add gnutls.$(O).
19911 (LIBS): Link to USER_LIBS.

19917 display_replaced_before_p argument into display_replaced_p, to
19918 make it consistent with the commentary. Fix typos in the
19921 * textprop.c (syms_of_textprop): Remove dead code.

19927 to changes in oldXMenu/XMenu.h from 2011-04-16.
19928 <menu_help_message, prev_menu_help_message>: Constify.
19929 (IT_menu_make_room): menu->help_text is now `const char **';

19933 to changes in oldXMenu/XMenu.h from 2011-04-16.
19934 (struct XMenu): Declare `help_text' `const char **'.

19945 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
19947 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
19950 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
19951 changes in globals.h immediately force recompilation.
19952 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19953 $(CURDIR)/s/ms-w32.h.
19954 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

19957 (syms_of_character): Don't defsubr it.
19958 <char-direction-table>: Deleted.
19960 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19962 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19963 * doprnt.c: Include limits.h.
19964 (SIZE_MAX): New macro.
19965 (doprnt): Return a size_t value. 2nd arg is now size_t.

20196 ns_descriptor_to_entity that were caused by using free to
20197 deallocate memory blocks that were allocated by xmalloc (via

20219 * process.c (send_process): Adjust to the new signatures of
20220 emacs_write and emacs_gnutls_write. Do not attempt to store

20440 * lisp.h (fatal_error_signal_hook): Remove decl.
20441 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.

20444 * editfns.c, lisp.h (get_operating_system_release): Remove.
20445 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20446 worth the hassle of breaking this out.
20448 * xterm.c: Make symbols static if they're not exported.
20449 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

20563 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20564 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20565 was inaccessible from Lisp.
20566 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.

20587 * xdisp.c (message_enable_multibyte): Now static.
20589 Declare Lisp_Object Q* variables to be 'static' if not exported.
20590 This makes it easier for human readers (and static analyzers)
20591 to see whether these variables are used from other modules.
20592 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

20603 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20605 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20607 Make Emacs functions such as Fatom 'static' by default.
20608 This makes it easier for human readers (and static analyzers)
20609 to see whether these functions can be called from other modules.
20610 DEFUN now defines a static function. To make the function external
20611 so that it can be used in other C modules, use the new macro DEFUE.
20612 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20613 (Finit_image_library):
20614 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

20617 Remove decls, since these functions are now static.
20618 (Funintern, Fget_internal_run_time): New decls, since these functions
20619 were already external.
20621 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20629 Mark functions with DEFUE instead of DEFUN,
20630 if they are used in other modules.
20631 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20632 decls for now-static functions.
20633 * buffer.h (Fdelete_overlay): Remove decl.

20669 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20671 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20672 when at ZV. (Bug#8487)
20674 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20676 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20682 * xsettings.c (read_and_apply_settings): Likewise.
20684 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20685 (overrun_check_free): Protoize.
20687 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20689 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20690 since callers should never pass a negative size.
20691 Change the signature to match that of plain 'read' and 'write'; see
20692 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20693 * lisp.h: Update prototypes of emacs_write and emacs_read.
20695 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20697 * xdisp.c (redisplay_window): Don't try to determine the character
20698 position of the scroll margin if the window start point w->startp
20699 is outside the buffer's accessible region. (Bug#8468)
20701 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20703 Fix write-region and its subroutines for buffers > 2GB.
20704 * fileio.c (a_write, e_write): Modify declaration of arguments and
20705 local variables to support buffers larger than 2GB.
20706 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20708 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20709 argument, local variables, and return value.
20711 * lisp.h: Update prototypes of emacs_write and emacs_read.
20713 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20715 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20717 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20719 Fix more problems found by GCC 4.6.0's static checks.
20721 * xdisp.c (vmessage): Use a better test for character truncation.
20723 * charset.c (load_charset_map): <, not <=, for optimization,
20724 and to avoid potential problems with integer overflow.
20725 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20726 * casetab.c (set_identity, shuffle): Likewise.
20727 * editfns.c (Fformat): Likewise.
20728 * syntax.c (skip_chars): Likewise.
20730 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20731 This also lets GCC 4.6.0 generate slightly better loop code.
20733 * callint.c (Fcall_interactively): <, not <=, for optimization.
20734 (Fcall_interactively): Count the number of arguments produced,
20735 not the number of arguments given. This is simpler and lets GCC
20736 4.6.0 generate slightly better code.
20738 * ftfont.c: Distingish more carefully between FcChar8 and char.
20739 The previous code passed unsigned char * to a functions like
20740 strlen and xstrcasecmp that expect char *, which does not
20741 conform to the C standard.
20742 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20743 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20744 char * when the C standard requires it.
20746 * keyboard.c (read_char): Remove unused var.
20748 * eval.c: Port to Windows vsnprintf (Bug#8435).
20749 Include <limits.h>.
20750 (SIZE_MAX): Define if the headers do not.
20751 (verror): Do not give up if vsnprintf returns a negative count.
20752 Instead, grow the buffer. This ports to Windows vsnprintf, which
20753 does not conform to C99. Problem reported by Eli Zaretskii.
20754 Also, simplify the allocation scheme, by avoiding the need for
20755 calling realloc, and removing the ALLOCATED variable.
20757 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20759 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20760 But keep the doprint source code for now, as we might revamp it
20761 and use it again (Bug#8435).
20762 * lisp.h (doprnt): Remove.
20763 * Makefile.in (base_obj): Remove doprnt.o.
20764 * deps.mk (doprnt.o): Remove.
20766 error: Print 32- and 64-bit integers portably (Bug#8435).
20767 Without this change, on typical 64-bit hosts error ("...%d...", N)
20768 was used to print both 32- and 64-bit integers N, which relied on
20769 undefined behavior.
20770 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20771 * lisp.h (error, verror): Mark as printf-like functions.
20772 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20773 Report overflow in size calculations when allocating printf buffer.
20774 Do not truncate output string at its first null byte.
20775 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20776 Truncate the output at a character boundary, since vsnprintf does not
20778 * charset.c (check_iso_charset_parameter): Convert internal
20779 character to string before calling 'error', since %c now has the
20781 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20782 overflow when computing char to be passed to 'error'. Do not
20783 pass Lisp_Object to 'error'; pass the integer instead.
20784 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20785 formatted with plain %d.
20787 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20789 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20791 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20793 * xterm.c (x_catch_errors): Remove duplicate declaration.
20795 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20797 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20799 2011-04-10 Jim Meyering <meyering@redhat.com>
20801 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20802 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20803 return ssize_t not "int", and use size_t as the buffer length.
20804 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20805 * gnutls.h: Update declarations.
20806 * process.c (read_process_output): Use ssize_t, to match.
20807 (send_process): Likewise.
20809 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20811 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20813 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20815 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20816 Use unsigned char, to match FcChar8 type definition.
20818 * xterm.c (handle_one_xevent):
20819 * xmenu.c (create_and_show_popup_menu):
20820 * xselect.c (x_decline_selection_request)
20821 (x_reply_selection_request): Avoid type-punned deref of X events.
20823 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20825 Fix some uses of `int' instead of EMACS_INT.
20826 * search.c (string_match_1, fast_string_match)
20827 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20828 (scan_buffer, find_next_newline_no_quit)
20829 (find_before_next_newline, search_command, Freplace_match)
20830 (Fmatch_data): Make some `int' variables be EMACS_INT.
20832 * xdisp.c (display_count_lines): 3rd argument and return value now
20833 EMACS_INT. All callers changed.
20834 (pint2hrstr): Last argument is now EMACS_INT.
20836 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20837 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20838 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20876 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20878 * keyboard.c (read_char): Call Lisp function help-form-show,
20879 instead of using internal_with_output_to_temp_buffer.
20880 (Qhelp_form_show): New var.
20881 (syms_of_keyboard): Use DEFSYM macro.
20883 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20898 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20900 Fix more problems found by GCC 4.6.0's static checks.
20902 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20904 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20906 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20908 * xdisp.c (vmessage): Mark as a printf-like function.
20910 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20915 printf-like functions.
20916 (tiff_load): Add casts to remove these marks before passing them
20917 to system-supplied API.
20919 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20921 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20922 This avoids several warnings with gcc -Wstrict-overflow.
20923 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20924 directly, rather than having caller test rule sign. This avoids
20925 some unnecessary tests.
20926 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20927 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20928 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20930 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20931 (xfont_open): Avoid unnecessary tests.
20933 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20935 * composite.h, composite.c (composition_gstring_put_cache):
20936 Use EMACS_INT, not int, for length.
20938 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20939 breaking out part of COMPOSITION_DECODE_RULE.
20940 (COMPOSITION_DECODE_RULE): Use it.
20941 * composite.c (get_composition_id): Remove unused local vars,
20942 by using the new macro.
20944 * textprop.c (set_text_properties_1): Change while to do-while,
20945 since the condition is always true at first.
20947 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20948 (interval_deletion_adjustment): Return unsigned value.
20951 * process.c (list_processes_1, create_pty, read_process_output):
20952 (exec_sentinel): Remove vars that were set but not used.
20953 (create_pty): Remove unnecessary "volatile"s.
20954 (Fnetwork_interface_info): Avoid possibility of int overflow.
20955 (read_process_output): Do adaptive read buffering even if carryover.
20956 (read_process_output): Simplify nbytes computation if buffered.

20960 * syntax.c (scan_words): Remove var that was set but not used.
20961 (update_syntax_table): Use unsigned instead of int.
20963 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20964 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20965 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20967 * print.c (print_error_message): Avoid int overflow.
20969 * font.c (font_list_entities): Redo for clarity,
20970 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20972 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20973 (font_score): Avoid potential overflow in diff calculation.
20975 * fns.c (substring_both): Remove var that is set but not used.
20976 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20978 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20980 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20981 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20982 can always succeed if overflow has undefined behavior.
20984 * search.c (boyer_moore, wordify): Remove vars set but not used.
20985 (wordify): Omit three unnecessary tests.
20987 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20988 All callers changed. This avoids the need for an unused var.
20990 * casefiddle.c (casify_region): Remove var that is set but not used.
20992 * dired.c (file_name_completion): Remove var that is set but not used.
20994 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20996 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20997 (Finsert_file_contents): Remove unnecessary code checking fd.
20999 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21000 Check for integer overflow on size calculations.
21002 * buffer.c (Fprevious_overlay_change): Remove var that is set
21005 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21006 Remove vars that are set but not used.
21007 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21008 (timer_check_2): Mark vars as initialized.
21010 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21012 * image.c (lookup_image): Remove var that is set but not used.
21013 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21015 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21016 that are set but not used.
21018 * xfns.c (make_invisible_cursor): Don't return garbage
21019 if XCreateBitmapFromData fails (Bug#8410).
21021 * xselect.c (x_get_local_selection, x_handle_property_notify):
21022 Remove vars that are set but not used.
21024 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21025 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21027 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21028 Remove var that is set but not used.
21029 (scroll_bar_windows_size): Now size_t, not int.
21030 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21031 Check for overflow.
21033 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21034 (map_tty_color) [!defined MSDOS]: Likewise.
21036 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21038 * coding.c: Remove vars that are set but not used.
21039 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21040 All callers changed.
21041 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21042 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21043 (decode_coding_charset): Remove vars that are set but not used.
21045 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21046 that is set but not used.
21048 * print.c (print_object): Remove var that is set but not used.
21050 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21051 The gnulib version avoids calling malloc in the usual case,
21052 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21053 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21054 * filelock.c (current_lock_owner): Likewise.
21055 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21056 * sysdep.c: Include allocator.h, careadlinkat.h.
21057 (emacs_no_realloc_allocator): New static constant.
21058 (emacs_readlink): New function.
21059 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21060 ../lib/careadlinkat.h.
21062 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21064 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21065 first non-nil return value).
21067 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21069 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21070 if not defined (Bug#8403).
21072 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21074 * xdisp.c (display_count_lines): Remove parameter `start',
21075 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21076 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21077 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21079 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21080 and thereabouts. All callers changed.
21081 (get_per_char_metric): Remove parameter `f', unused since
21082 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21084 2011-04-02 Jim Meyering <meyering@redhat.com>
21086 do not dereference NULL upon failed strdup
21087 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21088 (ns_get_family): Likewise.
21090 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21092 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21094 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21096 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21099 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21101 Add lexical binding.
21103 * window.c (Ftemp_output_buffer_show): New fun.
21104 (Fsave_window_excursion):
21105 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21107 * lread.c (lisp_file_lexically_bound_p): New function.
21108 (Fload): Bind Qlexical_binding.
21109 (readevalloop): Remove `evalfun' arg.
21110 Bind Qinternal_interpreter_environment.
21111 (Feval_buffer): Bind Qlexical_binding.
21112 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21114 (syms_of_lread): Declare `lexical-binding'.
21116 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21118 * keyboard.c (eval_dyn): New fun.
21119 (menu_item_eval_property): Use it.
21121 * image.c (parse_image_spec): Use Ffunctionp.
21123 * fns.c (concat, mapcar1): Accept byte-code-functions.
21125 * eval.c (Fsetq): Handle lexical vars.
21126 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21127 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21128 (FletX, Flet): Obey lexical binding.
21129 (Fcommandp): Handle closures.
21130 (Feval): New `lexical' arg.
21131 (eval_sub): New function extracted from Feval. Use it almost
21132 everywhere where Feval was used. Look up vars in lexical env.
21134 (Ffunctionp): Move from subr.el.
21135 (Ffuncall): Handle closures.
21136 (apply_lambda): Remove `eval_flags'.
21137 (funcall_lambda): Handle closures and new byte-code-functions.
21138 (Fspecial_variable_p): New function.
21139 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21140 but without exporting it to Lisp.
21142 * doc.c (Fdocumentation, store_function_docstring):
21143 * data.c (Finteractive_form): Handle closures.
21145 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21148 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21150 (exec_byte_code): New function extracted from Fbyte_code to handle new
21151 calling convention for byte-code-functions. Add new byte-codes.
21153 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21155 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21157 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21159 * xdisp.c (redisplay_internal): Fix prototype.
21161 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21163 * xdisp.c (SCROLL_LIMIT): New macro.
21164 (try_scrolling): Use it when setting scroll_limit.
21165 Limit scrolling to 100 screen lines.
21166 (redisplay_window): Even when falling back on "recentering",
21167 position point in the window according to scroll-conservatively,
21168 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21170 (try_scrolling): When point is above the window, allow searching
21171 as far as scroll_max, or one screenful, to compute vertical
21172 distance from PT to the scroll margin position. This prevents
21173 try_scrolling from unnecessarily failing when
21174 scroll-conservatively is set to a value slightly larger than the
21175 window height. Clean up the case of PT below the margin at bottom
21176 of window: scroll_max can no longer be INT_MAX. When aggressive
21177 scrolling is in use, don't let point enter the opposite scroll
21178 margin as result of the scroll.
21179 (syms_of_xdisp) <scroll-conservatively>: Document the
21180 threshold of 100 lines for never-recentering scrolling.
21182 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21184 * dispextern.h (move_it_by_lines):
21185 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21186 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21187 (message_log_check_duplicate): Remove parameters `prev_bol' and
21188 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21189 (redisplay_internal): Remove parameter `preserve_echo_area',
21190 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21192 * indent.c (Fvertical_motion):
21193 * window.c (window_scroll_pixel_based, Frecenter):
21194 Don't pass `need_y_p' to `move_it_by_lines'.
21196 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21198 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21199 steal a few bits to be more compact.
21200 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21201 Remove unneeded casts.
21203 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21205 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21207 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21208 binding" message (bug#7967).
21210 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21212 Fix more problems found by GCC 4.6.0's static checks.
21214 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21215 Remove unused local var.
21217 * editfns.c (Fmessage_box): Remove unused local var.
21219 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21220 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21221 Omit unused local vars.
21222 * window.c (shrink_windows): Omit unused local var.
21223 * menu.c (digest_single_submenu): Omit unused local var.
21224 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21225 Omit unused local var.
21227 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21228 Don't assume string length fits in int.
21229 (keyremap_step, read_key_sequence): Use size_t for sizes.
21230 (read_key_sequence): Don't check last_real_key_start redundantly.
21232 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21233 instead of alloca (Bug#8344).
21235 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21236 (Fbacktrace_frame): Don't assume nframes fits in int.
21238 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21240 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21243 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21245 * cm.c (calccost): Turn while-do into do-while, for clarity.
21247 * keyboard.c (syms_of_keyboard): Use the same style as later
21248 in this function when indexing through an array. This also
21249 works around GCC bug 48267.
21251 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21253 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21255 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21256 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21258 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21259 This avoids undefined behavior on integer overflow, and is a bit
21260 more convenient anyway since it is compared to a size_t variable.
21262 Variadic C functions now count arguments with size_t, not int.
21263 This avoids an unnecessary limitation on 64-bit machines, which
21264 caused (substring ...) to crash on large vectors (Bug#8344).
21265 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21266 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21267 All variadic functions and their callers changed accordingly.
21268 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21274 * fns.c (concat): Likewise.
21275 * frame.c (x_set_frame_parameters): Likewise.
21276 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21277 0 if not found, not -1. All callers changed.
21279 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21280 (stack_copy_size): Now size_t, not int.
21281 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21283 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21285 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21286 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21287 All callers changed.
21289 * lisp.h (multibyte_char_to_unibyte):
21290 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21291 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21292 * character.h (CHAR_TO_BYTE8):
21293 * cmds.c (internal_self_insert):
21294 * editfns.c (general_insert_function):
21295 * keymap.c (push_key_description):

21486 * buffer.c (Fkill_all_local_variables):
21487 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21489 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21490 unconditionally since it does the check itself.

21494 Fix more problems found by GCC 4.5.2's static checks.
21496 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21497 the first time through the loop, since we know p0 < p1 then.
21498 This also avoids a gcc -Wstrict-overflow warning.
21500 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21501 leading to a memory leak, possible in functions like
21502 load_charset_map_from_file that can allocate an unbounded number
21503 of objects (Bug#8318).
21505 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21506 that could (at least in theory) be that large.

21509 This is less likely to overflow, and avoids undefined behavior if
21510 overflow does occur. All callers changed. Use strtoul to scan
21511 for the unsigned long integer.
21512 (pint2hrstr): Simplify and tune code slightly.

21528 * process.c (Fmake_network_process): Use socklen_t, not int,
21529 where POSIX says socklen_t is required in portable programs.
21530 This fixes a porting bug on hosts like 64-bit HP-UX, where
21531 socklen_t is wider than int (Bug#8277).
21532 (Fmake_network_process, server_accept_connection):
21533 (wait_reading_process_output, read_process_output):
21536 * process.c: Rename or move locals to avoid shadowing.

21546 Make tparam.h and terminfo.c consistent.
21547 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21548 Include tparam.h instead, since it declares them.
21549 * cm.h (PC): Remove extern decl; tparam.h now does this.
21550 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21551 * terminfo.c: Include tparam.h, to check interfaces.
21552 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21553 (tparam): Adjust signature to match interface in tparam.h;
21554 this removes some undefined behavior. Check that outstring and len
21555 are zero, which they always are with Emacs.
21556 * tparam.h (PC, BC, UP): New extern decls.
21558 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21559 (xftfont_open): Rename locals to avoid shadowing.

21577 (composition_update_it): Mark var as initialized.
21578 (find_automatic_composition): Mark vars as initialized,
21579 with a FIXME (Bug#8290).

21585 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21586 to avoid shadowing.

21599 (alsa_choose_format): Remove unused local var.
21600 (wav_play): Initialize a variable to 0, to prevent undefined
21601 behavior (Bug#8278).
21603 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21605 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21607 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21608 clobbering (Bug#8298).
21609 * sysdep.c (sys_subshell): Likewise.
21610 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21612 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21613 This should get cleaned up, so that child_setup has the
21614 same signature on all platforms.
21616 * callproc.c (call_process_cleanup): Now static.
21617 (relocate_fd): Rename locals to avoid shadowing.
21619 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21621 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21622 not to be necessary, and produces flickering.
21624 2011-03-20 Glenn Morris <rgm@gnu.org>
21626 * config.in: Remove file.
21628 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21675 * unexelf.c (unexec): Name an expression,
21676 to avoid gcc -Wbad-function-cast warning.

21678 n rather than nn, a way that does not involve shadowing.
21679 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21681 * deps.mk (unexalpha.o): Remove; unused.

21746 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21747 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21748 some of which prompt warnings from gcc -Wbad-function-cast.
21749 (Fformat_time_string, Fencode_time, Finsert_char):
21750 (Ftranslate_region_internal, Fformat):
21751 Rename or remove local vars to avoid shadowing.

21776 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
21777 (GC_STRING_CHARS): Remove; not used.
21778 (Fmemory_limit): Cast sbrk's returned value to char *.
21780 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21781 avoids undefined behavior in theory.
21783 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21785 Use functions, not macros, for up- and down-casing (Bug#8254).
21786 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21787 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21788 to use the following functions instead of these macros.
21789 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21790 EMACS_INT, since callers assume the returned value fits in int.
21791 (upcase1): Likewise, for UPCASE_TABLE.
21792 (uppercasep, lowercasep, upcase): New static inline functions.
21793 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
21794 the race-condition problem in the old DOWNCASE.

21802 which gcc can warn about.
21803 (regex_compile, re_match_2_internal): Mark locals as initialized.
21804 (RETALLOC_IF): Define only if needed.
21805 (WORDCHAR_P): Likewise. This one is never needed, but is used
21806 only in a comment talking about a compiler bug, so put inside
21807 the #if 0 of that comment.
21808 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21809 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21812 * search.c (boyer_moore): Rename locals to avoid shadowing.

21835 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21836 New macros, so that the caller can use some names other than
21837 gcpro1, gcpro2, etc.
21838 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21840 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21841 argument, for consistency with GCPRO2_VAR, etc: it is now the
21842 prefix of the variable, not the variable itself. All uses
21844 * dired.c (directory_files_internal, file_name_completion):
21845 Rename locals to avoid shadowing.
21847 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21848 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21849 dired.c's scmp function, had undefined behavior.
21850 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21851 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21852 * buffer.h: ... to here, because these macros use current_buffer,
21853 and the new implementation with inline functions needs to have
21854 current_buffer in scope now, rather than later when the macros
21856 (downcase, upcase1): New static inline functions.
21857 (DOWNCASE, UPCASE1): Reimplement using these functions.
21858 This avoids undefined behavior in expressions like
21859 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21860 from race conditions in accessing the global variables
21861 case_temp1 and case_temp2.
21862 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21863 * lisp.h (case_temp1, case_temp2): Remove their decls.
21864 * character.h (ASCII_CHAR_P): Move from here ...
21865 * lisp.h: ... to here, so that the inline functions mentioned
21866 above can use them.
21868 * dired.c (directory_files_internal_unwind): Now static.
21870 * fileio.c (file_name_as_directory, directory_file_name):
21871 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21873 (file_name_as_directory): Use const pointers when appropriate.
21874 (Fexpand_file_name): Likewise. In particular, newdir might
21875 point at constant storage, so make it a const pointer.
21876 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21877 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21879 (Fset_file_times, Finsert_file_contents, auto_save_error):

21884 to avoid shadowing.
21886 * marker.c (bytepos_to_charpos): Remove; unused.
21888 * lisp.h (verify_bytepos, count_markers): New decls,
21889 so that gcc does not warn that these functions aren't declared.
21891 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21892 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21893 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21894 (copy_text): Remove unused local var.
21896 * filelock.c (within_one_second): Now static.
21897 (lock_file_1): Rename local to avoid shadowing.
21899 * buffer.c (fix_overlays_before): Mark locals as initialized.
21900 (fix_start_end_in_overlays): Likewise. This function should be
21901 simplified by using pointers-to-pointers, but that's a different
21903 (switch_to_buffer_1): Now static.
21904 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21905 (report_overlay_modification): Rename locals to avoid shadowing.
21907 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21908 Fix pointer signedness issue.
21909 (sys_subshell): Mark local as volatile if checking for lint,
21910 to suppress a gcc -Wclobbered warning that does not seem to be right.
21911 (MAXPATHLEN): Define only if needed.
21913 * process.c (serial_open, serial_configure): Move decls from here ...
21914 * systty.h: ... to here, so that they can be checked.
21916 * fns.c (get_random, seed_random): Move extern decls from here ...
21917 * lisp.h: ... to here, so that they can be checked.
21919 * sysdep.c (reset_io): Now static.
21920 (wait_for_termination_signal): Remove; unused.
21922 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21923 (copy_keymap_item, append_key, push_text_char_description):
21925 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21926 (DENSE_TABLE_SIZE): Remove; unused.
21927 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21928 (describe_map_tree):
21929 Rename locals to avoid shadowing.
21931 * keyboard.c: Declare functions static if they are not used elsewhere.

22079 1152921504606846976) returns the obviously-bogus value (-948597
22080 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22081 reports time overflow. See
