104 Use bool for boolean.
105 * region-cache.c (region_cache_forward, region_cache_backward):

229 * sysdep.c (list_system_processes)
230 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
231 Make it a stub in this case; otherwise the build might fail,
232 and this code hasn't been tested on such hosts anyway.
233 Problem reported by Nelson H. F. Beebe in
234 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
235 and analyzed by Jérémie Courrèges-Anglas in
236 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
238 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
240 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.

246 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
248 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
249 * filelock.c: Include <c-ctype.h>.
250 (MAX_LFINFO): New top-level constant.
251 (lock_info_type): Remove members pid, boot_time. Add members at,
252 dot, colon. Change user member to be the entire buffer, not a
253 pointer. This allows us to handle the case where a foreign
254 pid or boot time exceeds the local range. All uses changed.
255 (LINKS_MIGHT_NOT_WORK): New constant.
256 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
257 (defined_WINDOWSNT): Remove.
258 (MAKE_LOCK_NAME, file_in_lock_file_name):
259 Always use .#FILE (not .#-FILE) for the file lock,
260 even if it is a regular file.
261 (rename_lock_file): New function.
262 (create_lock_file): Use it.
263 (create_lock_file, read_lock_data):
264 Prefer a symbolic link for the lock file, falling back on a
265 regular file if symlinks don't work. Do not try to create
266 symlinks on MS-Windows, due to security hassles. Stick with
267 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
268 link, rename, unlink, mkstemp) when creating locks, as a GNUish
269 host may be using a Windowsish file system, and cannot use
270 MS-Windows-only system calls. Fall back on mktemp if mkstemp
271 doesn't work. Don't fail merely because of a symlink-contents
272 length limit in the current file system; fall back on regular
273 files. Increase the symlink contents length limit to 8 KiB, this
274 should be big enough for any real use and doesn't crunch the
276 (create_lock_file, lock_file_1, read_lock_data):
277 Simplify allocation of lock file buffers now that they fit in 8 KiB.
278 (lock_file_1): Return error number, not bool. All callers changed.
279 (ELOOP): New macro, if not already defined.
280 (read_lock_data): Return size of lock file contents, not Lisp object.
281 All callers changed. Handle a race condition if some other process
282 replaces a regular-file lock with a symlink lock or vice versa,
283 while we're trying to read the lock.
284 (current_lock_owner): Parse contents more carefully, to help avoid
285 confusing a regular-file lock with some other application's use
286 of the file. Check for lock file contents being too long, or
287 not parsing correctly.
288 (current_lock_owner, lock_file):
289 Allow foreign pid and boot times that exceed the local range.
290 (current_lock_owner, lock_if_free, lock_file):
291 Simplify allocation of lock file contents.
292 * w32.c (sys_rename_replace): New function, containing most of
293 the contents of the old sys_rename.
294 (sys_rename): Use it.
295 (fchmod): New dummy function.
296 * w32.h (sys_rename_replace, fchmod): New decls.
298 2013-03-05 Eli Zaretskii <eliz@gnu.org>
300 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
301 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
302 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
303 <dmantipov@yandex.ru>.
305 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
307 * composite.c (get_composition_id, fill_gstring_header):
308 Use make_uninit_vector where appropriate.
309 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
310 * xselect.c (clean_local_selection_data): Likewise.
312 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
314 Fix misuse of ImageMagick that caused core dump (Bug#13846).
315 * image.c (imagemagick_load_image): Calculate height and width
316 after flattening the image, not before.
318 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
320 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
321 * ftfont.c (ftfont_shape_by_flt): Likewise.
322 * w32uniscribe.c (uniscribe_shape): Likewise.
324 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
326 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
327 The old approach, which fell back on DIR/.#FILE.0 through
328 DIR/.#FILE.9, had race conditions that could not be easily fixed.
329 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
330 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
331 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
332 because the locking mechanism was never reliable in that case).
333 This patch fixes this and other bugs discovered by a code
334 inspection that was prompted by
335 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
336 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
337 to avoid interoperability problems between the MS-Windows and
338 non-MS-Windows implementations. MS-Windows and non-MS-Windows
339 instances of Emacs now ignore each others' locks.
340 * filelock.c (defined_WINDOWSNT): New constant.
341 (MAKE_LOCK_NAME, fill_in_lock_file_name):
342 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
343 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
344 regular files on MS-Windows hosts.
345 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
346 Use SAFE_ALLOCA to avoid problems with long file names.
347 (MAX_LFINFO): Now a local constant, not a global macro.
348 (IS_LOCK_FILE): Remove.
349 (lock_file_1): Don't inspect errno if symlink call succeeds;
351 (lock_file): Document that this function can return if lock
353 (lock_file): Don't access freed storage.
355 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
357 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
359 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
361 * textprop.c: Use bool for booleans.
362 (validate_interval_range, Fadd_text_properties)
363 (Fremove_text_properties): Prefer bool to int when either works.
365 2013-03-02 Eli Zaretskii <eliz@gnu.org>
367 * textprop.c (Fadd_text_properties, Fremove_text_properties):
368 If the interval tree changes as a side effect of calling
369 modify_region, re-do processing starting from the call to
370 validate_interval_range. (Bug#13743)
372 2013-02-28 Eli Zaretskii <eliz@gnu.org>
374 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
377 2013-02-27 Eli Zaretskii <eliz@gnu.org>
379 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
380 _SH_DENYRW flag, instead of emacs_open, to deny any other process
381 access to the lock file until it is written and closed.
384 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
386 * callint.c (Qcall_interactively):
387 * macros.c (Qexecute_kbd_macro):
390 2013-02-26 Bastien Guerry <bzg@gnu.org>
392 * window.c (Frecenter): Tiny docstring enhancement.
394 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
396 Minor textprop integer cleanup.
397 * intervals.h, textprop.c (add_text_properties_from_list):
398 Return void, not int, since nobody uses the return value.
399 * textprop.c (validate_plist, add_properties, remove_properties)
400 (Fadd_text_properties):
401 Don't assume list length fits in int.
402 (interval_has_all_properties, interval_has_some_properties)
403 (interval_has_some_properties_list, add_properties, remove_properties)
404 (Fadd_text_properties, Fremove_text_properties)
405 (Fremove_list_of_text_properties, text_property_stickiness):
406 Use bool for booleans.
407 (Fadd_text_properties, Fremove_text_properties):
408 (Fremove_list_of_text_properties):
409 Reindent do-while as per GNU style.

413 Implement CLASH_DETECTION for MS-Windows.
415 * filelock.c [WINDOWSNT]: Include w32.h.
416 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
417 function of that name. Up-case the macro arguments.
418 (IS_LOCK_FILE): New macro.
419 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
420 (create_lock_file): New function, with body extracted from
422 [WINDOWSNT]: Implement lock files by writing a regular file with
423 the lock information as its contents.
424 (read_lock_data): New function, on Posix platforms just calls
426 [WINDOWSNT]: Read the lock info from the file.
427 (current_lock_owner): Call read_lock_data instead of calling
428 emacs_readlinkat directly.
429 (lock_file) [WINDOWSNT]: Run the file name through
432 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
433 just check if the process by that PID exists.
435 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
436 also present, as doing so will fail to error out if the file
439 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
441 * textprop.c (Fadd_text_properties, Fremove_text_properties)
442 (Fremove_list_of_text_properties): Skip all of the intervals in
443 the region between START and END that already have resp. don't
444 have the requested properties, not just the first one.
445 Add assertions that the loop afterwards always modifies the
446 properties. (Bug#13743)
448 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

459 (START_FILES): Remove. All uses removed.
460 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
461 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
462 (buildobj.h): Use it.
463 ($(ALLOBJS)): Depend on globals.h.
464 (temacs$(EXEEXT)): Use $(ALLOBJS).
465 * autodeps.mk (ALLOBJS): Move to Makefile.in.
466 * deps.mk (vm-limit.o):
467 * makefile.w32-in ($(BLD)/vm-limit.$(O)):

476 * vm-limit.c: Move most of mem-limits.h's contents here.
477 (data_start): New decl. It's OK if this is approximate,
478 so simplify-away some unnecessary exactness.
479 (POINTER): Remove; all uses removed.
480 (data_space_start): Now char *, to avoid casts.
481 (exceeds_lisp_ptr): New function, replacing the old
482 EXCEEDS_LISP_PTR macro. All uses changed.
483 (check_memory_limits): Simplify and remove casts.
484 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
485 (memory_warnings): Use data_start instead of start_of_data.
487 2013-02-24 Andreas Schwab <schwab@linux-m68k.org>
489 * xdisp.c (set_message): Only check for debug-on-message if STRING
490 is a string. (Bug#13797)

495 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
496 2012-07-10 patch to this file. Reported by Eli Zaretskii in
497 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
498 and diagnosed by Andreas Schwab in
499 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
501 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
503 Assume C89 or better.
504 * ralloc.c (SIZE, POINTER, NIL):
505 * vm-limit.c (POINTER):
506 Remove, replacing all uses with C89 equivalents. These old
507 symbols were present only for porting to pre-C89 platforms.
509 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
511 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
512 This avoids warning messages reported as part of Bug#13546.
514 2013-02-21 Ken Brown <kbrown@cornell.edu>
516 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
518 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
520 * sheap.c (report_sheap_usage): Prefer message1_nolog.
522 * keyboard.c (Qcommand_execute): New var.
523 (command_loop_1, read_char): Use it.
524 (Fcommand_execute): Remove, replace by an Elisp implementation.
525 (syms_of_keyboard): Adjust accordingly.
527 2013-02-19 Daniel Colascione <dancol@dancol.org>
529 * sheap.c (report_sheap_usage): Use message, not message1, so
530 that we don't try to create a buffer while we're in the middle
531 of dumping Emacs. Explain why.
533 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
535 * search.c (find_newline): Return byte position in bytepos.

545 (get_visually_first_element, move_it_vertically_backward):
546 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
548 2013-02-19 Eli Zaretskii <eliz@gnu.org>
550 * w32proc.c (new_child): Avoid leaking handles if the subprocess
551 resources were not orderly released.

555 * xdisp.c (x_draw_vertical_border): For a window that is neither
556 the leftmost nor the rightmost, redraw both the left and the right
557 vertical borders. (Bug#13723)

582 unconditionally. (Bug#9066)
584 * w32.c (set_errno): Reset h_errno and don't set it to any other
585 value. Set errno instead.

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

630 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
632 Fix AIX port (Bug#13650).
633 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
634 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
635 was #undeffed earlier, so it cannot be used as a macro here.
636 Use the constant and not the macro.
638 2013-02-15 Eli Zaretskii <eliz@gnu.org>
640 * w32proc.c (new_child): If no vacant slots are found in
641 child_procs[], make another pass looking for slots whose process

648 STATUS_READ_IN_PROGRESS. (Bug#13546)
650 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
652 * gtkutil.c (tb_size_cb): New function.

657 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
660 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
662 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
664 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

672 2013-02-13 Glenn Morris <rgm@gnu.org>
674 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
676 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
678 Improve AIX port some more (Bug#13650).
679 With this, it should be as good as it was in 23.3, though it's
680 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
681 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
682 * unexaix.c (start_of_text): Remove.
683 (_data, _text): Declare as char[], not int, as AIX manual suggests.
684 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
685 (orig_load_scnptr, orig_data_scnptr):
686 Now off_t, not long, since they are file offsets.
687 (make_hdr): Use _data, not start_of_data ().
688 This is the key part of the fix.
689 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
690 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
692 * pre-crt0.c (data_start): Initialize to 1.
693 This ports to compilers that optimize the external declaration
694 'int x = 0;' as if it were 'int x;' to shrink the executable.
696 Improve AIX port (Bug#13650).
697 This doesn't fix the bug, but it makes progress: Emacs builds now.
698 * unexaix.c: Include inttypes.h, stdarg.h.
699 (report_error, report_error_1): Mark as _Noreturn.
700 (report_error): Don't report the wrong errno.
701 (report_error_1): Now varargs. All callers changed.
702 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
703 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
704 (write_ptr): Use %p to print address rather than %lx and a cast
705 to unsigned long. Grow buffer a bit, to be safer.
707 2013-02-13 Eli Zaretskii <eliz@gnu.org>
709 * bidi.c (bidi_resolve_neutral): After finding the next
710 non-neutral character, accept NEUTRAL_ON type as well, because
711 directional control characters, such as LRE and RLE, have their
712 type converted to that by bidi_resolve_weak. This avoids aborts
713 when LRE/RLE follows a run of neutrals.
714 (bidi_move_to_visually_next): Assert that return value of
715 bidi_peek_at_next_level is non-negative. Negative values will
718 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
720 Minor getenv-related fixes.
721 * callproc.c (Fcall_process_region) [!DOS_NT]:
722 Avoid unnecessary duplicate call to getenv.
723 * callproc.c (init_callproc):
724 * dispnew.c (init_display):
725 * sysdep.c (sys_subshell):
726 Omit unnecessary cast of getenv or egetenv.
728 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
730 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
733 2013-02-12 Eli Zaretskii <eliz@gnu.org>
735 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
737 (display_line): Set w->region_showing to the value of
738 it->region_beg_charpos, not to -1. This fixes redisplay
739 optimization when cursor is moved up after M->. (Bug#13623)
741 (try_scrolling): Scroll text up more if point is too close to ZV
742 and inside the scroll margin. This makes sure point is moved
743 outside the scroll margin in these cases.
745 * window.h (struct window): region_showing can no longer be
748 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
750 Tune by using memchr and memrchr.
751 * doc.c (Fsnarf_documentation):
752 * fileio.c (Fsubstitute_in_file_name):
753 * search.c (find_newline, scan_newline):
754 * xdisp.c (pos_visible_p, display_count_lines):
755 Use memchr and memrchr rather than scanning byte-by-byte.
756 * search.c (find_newline): Rename from scan_buffer.
757 Omit first arg TARGET, as it's always '\n'. All callers changed.
759 Clean up read_key_sequence a tiny bit more.
760 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
761 (read_key_sequence): Remove unused locals.
763 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
765 Clean up read_key_sequence a bit; reread active keymaps after first event.
766 * keyboard.c (read_char, read_char_x_menu_prompt)
767 (read_char_minibuf_menu_prompt):
768 Replace nmaps+maps with a single `map' arg.
769 (follow_key): Operate on a single map.
770 (active_maps): New function.
771 (test_undefined): Also return true for nil bindings.
772 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
773 a single (composed) keymap. Remember `first_event' to choose the right
774 set of active keymaps. Recompute the set of keymaps after receiving
775 the first event. Remove GOBBLE_FIRST_EVENT.
776 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
777 * keyboard.h (read_char): Update declaration.
778 * lread.c (read_filtered_event): Adjust call to read_char.
780 2013-02-11 Eli Zaretskii <eliz@gnu.org>
782 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
783 Don't use the limitation on backwards movement when lines are truncated
784 in the window. (Bug#13675)
786 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
788 * marker.c (set_marker_internal): If desired position is passed
789 as a marker, avoid call to buf_charpos_to_bytepos.
790 * window.c (Fset_window_point): Omit redundant type checking.
791 (Fset_window_start): Likewise. Format comment.
792 (window_scroll_pixel_based): Use set_marker_restricted_both
793 with character and byte positions obtained from an iterator.
794 (Fset_window_configuration): Use set_marker_restricted_both.
795 * xdisp.c (message_dolog): Likewise.
797 2013-02-10 Eli Zaretskii <eliz@gnu.org>
799 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
800 When text lines are longer than window's screen lines, don't move back
801 too far. This speeds up some redisplay operations. (Bug#13675)
803 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
805 * syntax.c (scan_sexps_forward): Fix byte position calculation
806 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
808 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
810 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
813 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
815 Minor hashing refactoring.
816 * fns.c (SXHASH_REDUCE): Move to lisp.h.
817 (sxhash_float): Return EMACS_UINT, for consistency with the other
819 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
820 non-static inline function and therefore can't use static vars.
821 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
822 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
823 with the other hash functions.
825 2013-02-09 Eli Zaretskii <eliz@gnu.org>
827 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
828 XXXXXX part of the temporary file pattern is not downcased even
829 when w32-downcase-file-names is non-nil. (Bug#13661)
831 * xdisp.c (decode_mode_spec): Remove handling of %t.
833 * msdos.c (careadlinkatcwd): Remove.
835 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
837 * lread.c (skip_dyn_bytes): New function (bug#12598).

839 (load_each_byte): Remove. Update users.
841 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
843 * search.c (scan_buffer): Calculate end byte position just once.
844 (scan_newline): Do not recalculate start_byte.
845 (search_command): Use eassert.
846 * syntax.c (struct lisp_parse_state): New member location_byte.
847 (scan_sexps_forward): Record from_byte and avoid redundant
848 character to byte position calculation ...

870 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
872 * coding.c (Fdefine_coding_system_internal): Use AREF where
873 argument is known to be a vector.
874 * fns.c (Flocale_info): Likewise for ASET.
875 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.

885 updateCollectionBehaviour.
887 * nsterm.m (NEW_STYLE_FS): Remove.
888 (ns_last_use_native_fullscreen): New variable.
889 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
890 (x_set_window_size): Do not take title bar and tool bar into account
891 if isFullscreen returns YES.
892 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
893 (check_native_fs): New function.
894 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
895 (ns_term_init): Remove NEW_STYLE_FS.
896 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
897 and tool bar if isFullscreen returns NO.
898 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
899 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
901 (window:willUseFullScreenPresentationOptions:): New method.
902 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
903 Hide toolbar if not enabled (Bug#13444).
904 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
905 Restore tool bar if enabled, hide it otherwise (Bug#13444).
906 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
907 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
908 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
909 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
910 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
911 (syms_of_nsterm): Add ns-use-native-fullscreen.
913 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
915 * fileio.c (Qchoose_write_coding_system): Now static.
917 2013-02-04 Eli Zaretskii <eliz@gnu.org>
919 * xdisp.c (window_buffer_changed): region_showing can be negative,
920 which still means region is being displayed.
921 (redisplay_internal): Resurrect code that forced redisplay of the
922 whole window when showing region and the mark has changed.
923 Record the new mark position to allow redisplay optimizations.
924 (display_line): If it->region_beg_charpos is non-zero, set the
925 window's region_showing member to -1. (Bug#13623) (Bug#13626)
927 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
928 not bitfield of 1 bit.
930 2013-02-03 Daniel Colascione <dancol@dancol.org>
932 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
933 daemon mode works on cygw32 when Emacs is installed and not just
936 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
938 Avoid file time stamp bug on MS-Windows (Bug#13149).
939 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
940 as FAT32 doesn't update time stamps when truncating them.
941 Also, check that a file time stamp is not a multiple of 100 ns;
942 this should catch all instances of the problem on MS-Windows,
943 as its native file system resolution is 100 ns or worse, and
944 checking for a non-multiple of 100 ns should impose only a small
945 overhead on systems with ns resolution.
947 2013-02-02 Eli Zaretskii <eliz@gnu.org>
949 Avoid encoding file names on MS-Windows when they need to be run
950 through dostounix_filename.
951 * w32.c (normalize_filename): Accept an additional argument
952 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
953 downcase it even if w32-downcase-file-names is non-nil.
954 (dostounix_filename): Accept an additional argument MULTIBYTE and
955 pass it to normalize_filename.

958 * msdos.h (dostounix_filename): Adjust prototype.
960 * w32.h (dostounix_filename): Adjust prototype.
962 * msdos.c (dostounix_filename): Accept an additional argument and
964 (init_environment): Adjust callers of dostounix_filename.
966 * fileio.c (Ffile_name_directory, file_name_as_directory)
967 (directory_file_name, Fexpand_file_name)
968 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
970 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
972 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
973 variables, as egetenv is case-insensitive for DOS_NT.
975 * dired.c (file_name_completion): Don't call Fdirectory_file_name
976 with an encoded file name.
978 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
979 Adjust calls to dostounix_filename.
981 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.

987 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
990 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
993 * callproc.c (Fcall_process): Make sure program name in PATH and
994 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
995 is passed to exec/spawnve, which fails unless the file-name
998 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
999 even if w32-quote-process-args is nil.
1001 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1003 Fix timestamp bug when write-region appends nothing (Bug#13149).
1004 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1005 the file's time stamp doesn't change if Emacs happens to write nothing
1006 to the file, and on a buggy file system this could cause Emacs to
1007 incorrectly infer that the file system doesn't have the bug.
1008 Avoid this problem by inhibiting the inference in this case.
1010 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1012 * window.h (struct window): Convert base_line_number, base_line_pos
1013 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1014 Convert region_showing member from Lisp_Object to bitfield.
1015 Remove sequence_number member. Adjust comments.
1016 * window.c (sequence_number): Remove.
1017 (make_window): Initialize column_number_displayed.
1018 * print.c (print_object): Follow the printed representation of
1019 frames and print window pointer to distinguish between windows.
1020 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1021 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1022 (wset_column_number_displayed, wset_region_showing): Remove.
1023 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1024 (try_scrolling, try_cursor_movement, redisplay_window)
1025 (try_window_reusing_current_matrix, try_window_id, display_line)
1026 (display_mode_lines, decode_mode_spec): Adjust users.
1027 * .gdbinit (pwinx): Do not print sequence_number.
1029 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1031 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1032 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1033 * dired.c: Include <fcntl.h>.
1034 (open_directory): New function, which uses open and fdopendir
1035 rather than opendir. DOS_NT platforms still use opendir, though.
1036 (directory_files_internal, file_name_completion): Use it.
1037 (file_attributes): New function, with most of the old Ffile_attributes.
1038 (directory_files_internal, Ffile_attributes): Use it.
1039 (file_attributes, file_name_completion_stat): First arg is now fd,
1040 not dir name. All uses changed. Use fstatat rather than lstat +
1042 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1043 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1044 (emacs_readlinkat): New function, with much of the old
1045 Ffile_symlink_p, but with an fd argument for speed.
1046 It uses readlinkat rather than careadlinkatcwd, so that it
1047 need not assume the working directory.
1048 (Ffile_symlink_p): Use it.
1049 * filelock.c (current_lock_owner): Use emacs_readlinkat
1050 rather than emacs_readlink.
1051 * lisp.h (emacs_readlinkat): New decl.
1052 (READLINK_BUFSIZE, emacs_readlink): Remove.
1053 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1054 (emacs_norealloc_allocator, emacs_readlink): Remove.
1055 This stuff is moved to fileio.c.
1056 * w32.c (fstatat, readlinkat): New functions.
1057 (careadlinkat): Don't check that fd == AT_FDCWD.
1058 (careadlinkatcwd): Remove; no longer needed.

1063 (Fwrite_region): Update for new choose_write_coding_system args.
1064 Move the last piece of choose_write_coding_system here. (Bug#13522)
1065 (syms_of_fileio): Add choose-write-coding-system.
1067 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1069 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1070 (sys_close): Zero out the flags for the file descriptor before
1071 closing it. (Bug#13546)
1073 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1074 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1075 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1078 * w32.c (w32_get_long_filename, init_environment, readlink):
1079 Support file names encoded in DBCS codepages.
1080 (readlink): Use the current file-name-coding-system, not the ANSI
1081 codepage, to decode and handle targets of symlinks.
1083 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1085 * w32.c (opendir): Now accepts a 'const char *'.
1087 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1089 Remove obsolete redisplay code. See the discussion at
1090 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1091 * dispnew.c (preemption_period, preemption_next_check): Remove.
1092 (Vredisplay_preemption_period): Likewise.
1093 (update_frame, update_single_window, update_window, update_frame_1):
1094 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1095 used, following the 2012-06-22 change.
1097 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1099 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1101 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1103 * font.c (num_fonts): Remove the leftover from old
1104 debugging code. Adjust comment style here and there.
1105 * insdel.c (insert_1): Remove.
1106 * lisp.h (insert_1): Remove prototype.
1107 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1109 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1111 * w32.c (max_filename_mbslen): New function.
1112 (normalize_filename, readdir): Use it to detect locales where ANSI
1113 encoding of file names uses a double-byte character set (DBCS).
1114 If a DBCS encoding is used, advance by characters using
1115 CharNextExA, instead of incrementing a 'char *' pointer.
1116 Use _mbslwr instead of _strlwr. (Bug#13515)
1118 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1119 request of memory reservation to 1.7GB. (Bug#13065)
1121 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1123 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1124 at check_extra_latin label. (Bug#13505)
1126 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1128 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1129 Avoid redundant calls to strlen.
1131 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1133 Drop async_visible and async_iconified fields of struct frame.
1134 This is possible because async input is gone; for details, see
1135 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1136 * frame.h (struct frame): Remove async_visible and async_iconified
1137 members, convert garbaged to unsigned bitfield. Adjust comments.
1138 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1139 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1140 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1141 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1142 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1144 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1145 properly. Likewise for obscured.
1147 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1150 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1152 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1154 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1155 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1157 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1159 * xdisp.c (message2, message2_nolog): Remove functions.
1160 (message3, message3_nolog): Extract nbytes and multibyteness directly
1161 from the string. Change all callers.
1162 (message3_nolog): Don't set message_enable_multibyte since set_message
1163 will reset it anyway.
1164 (message1, message1_nolog): Use message3.
1165 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1166 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1167 (set_message): Drop all but the second arg, which has to be a string.
1168 (set_message_1): Simplify now that we know that a1 is NULL and the
1169 second arg is a string.
1170 * frame.h (struct frame): Remove `message_buf' field.
1171 Use glyphs_initialized_p instead.
1172 (FRAME_MESSAGE_BUF): Remove macro.
1173 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1174 * lisp.h (message2, message2_nolog): Remove declarations.
1175 (message3, message3_nolog): Update declarations.
1176 * keyboard.c (read_char_minibuf_menu_text)
1177 (read_char_minibuf_menu_width): Remove vars.
1178 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1179 to correctly handle multibyte strings.
1180 * frame.c (delete_frame): Don't free message_buf any more.
1181 * editfns.c (message_text, message_length): Remove vars.
1182 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1183 * fileio.c (auto_save_error): Use message3 instead of message2.
1184 * dispnew.c (adjust_frame_message_buffer): Remove function.
1186 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1188 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1189 real estate used for the tool bar and the menu bar.
1191 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1193 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1194 hidden buffer is prepared to modification (Bug#13164).
1196 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1198 * window.h (struct window): Change window_end_valid member from
1199 Lisp_Object to a bitfield. Adjust comments.
1200 (wset_window_end_valid): Remove.
1201 * window.c (adjust_window_count): Clear window_end_valid.
1202 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1203 (Fwindow_line_height, set_window_buffer, Frecenter)
1204 (Fsplit_window_internal, Fdelete_other_windows_internal)
1205 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1206 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1207 * xdisp.c (check_window_end, reconsider_clip_changes)
1208 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1209 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1210 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1212 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1214 * xdisp.c (mark_window_display_accurate): Simplify the loop
1215 assuming that the only one of vchild, hchild or buffer window
1216 slots is non-nil. Call mark_window_display_accurate_1 for
1217 the leaf windows only.
1218 (mark_window_display_accurate_1): Always assume leaf window.
1221 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1223 * emacs.c (Qkill_emacs_hook): Now static.
1225 * fileio.c (Finsert_file_contents): Simplify.
1226 Remove unnecessary assignments and tests.
1228 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1230 * w32.c (acl_set_file): Don't test for errors unless
1231 set_file_security returns FALSE. Avoids spurious errors when
1234 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1236 * fileio.c (Finsert_file_contents): Revert code introduced at
1237 2013-01-18 in favor of the simpler and generally better fix.
1238 Save stack space by removing 'buffer' and reusing 'read_buf'
1241 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1243 * lisp.h (eabs): Define unconditionally (Bug#13419).
1244 The old "#if !defined (eabs)" was an unnecessary revenant of back
1245 when this macro was called "abs". Document 'eabs' better.
1247 2013-01-19 Glenn Morris <rgm@gnu.org>
1249 * fns.c (Frandom): Doc fix.
1251 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1253 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1254 segfault when there are lots of overlays.
1256 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1257 when there are lots of overlays.
1258 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1259 for the details and a way to reproduce.
1261 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1263 * fileio.c: Use O_APPEND to append.
1264 This corresponds better to the natural interpretation of "append",
1265 and avoids the need to open the output file twice, or to invoke
1266 lseek when APPEND is neither nil nor a number.
1267 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1268 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1269 file possibly twice, and lseeking to its end; this avoids the
1270 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1271 at the same time: the combination is never needed and apparently
1272 it doesn't work with DOS_NT.
1274 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1275 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1277 Allow floating-point file offsets.
1278 Problem reported by Vitalie Spinu in
1279 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1280 * fileio.c (emacs_lseek): Remove.
1281 (file_offset): New function.
1282 (Finsert_file_contents, Fwrite_region): Use it.
1284 2013-01-19 Chong Yidong <cyd@gnu.org>
1286 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1287 aborting on Fsignal (Bug#13289).
1289 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1291 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1292 set_file_security as failure due to insufficient privileges.
1293 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1294 (fstat): Return owner and group like 'stat' and 'lstat' do.
1296 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1298 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1299 The bug was observed on Ubuntu operating inside a virtual machine,
1300 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1301 The workaround introduces a race condition on non-buggy hosts,
1302 but it's an unlikely race and anyway there's a nearly identical
1303 nearby race that can't be fixed.
1304 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1306 (Fwrite_region): Test for file system time stamp bug.
1307 (init_fileio): New function.
1308 * lisp.h (init_fileio): Declare it.
1309 * emacs.c (main): Call it.
1311 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1312 and make it more consistent with other stat-failure diagnostics.
1314 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1316 Fix crash when inserting data from non-regular files.
1317 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1318 for the error description produced by valgrind.
1319 * fileio.c (read_non_regular): Rename to read_contents.
1320 Free Lisp_Save_Value object used to pass parameters.
1321 (read_non_regular_quit): Rename to read_contents_quit.
1322 (Finsert_file_contents): Redesign internal file reading loop to adjust
1323 gap and end positions after each read and so help make_gap to work
1324 properly. Do not signal an I/O error too early and so do not leave
1325 not yet decoded characters in a buffer, which was the reason of
1326 redisplay crash. Use list2 to build return value. Adjust comments.
1328 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1330 Close a race when statting and reading files (Bug#13149).
1331 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1332 This avoids a race if the file is renamed between stat and open.
1333 This race is not the problem originally noted in Bug#13149;
1334 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1336 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1338 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
1339 objects, related functions and macros.

1342 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
1343 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1344 * alloc.c (format_save_value): Rename to make_save_value.
1345 (make_save_pointer): New function.
1346 (record_xmalloc): Use make_save_pointer.
1347 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1348 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1349 Change users of make_save_value to make_save_pointer.
1350 Likewise for format_save_value and make_save_value.
1352 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1354 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
1355 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
1356 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
1359 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
1361 * alloc.c (free_save_value): Now static.
1363 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1365 * keymap.c (map_keymap_internal): Use format_save_value.
1366 (map_keymap_char_table_item): Adjust accordingly.
1367 * fileio.c (non_regular_fd, non_regular_inserted)
1368 (non_regular_nbytes): Remove.
1369 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1370 Use format_save_value to pass parameters to read_non_regular.
1371 (read_non_regular): Use XSAVE_ macros to extract parameters.
1373 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1375 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1377 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1379 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1380 extraction from any Lisp_Save_Value slot. Add type checking.
1381 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1382 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1383 * xselect.c: All users changed.
1385 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1387 Some convenient bits to deal with Lisp_Save_Values.
1388 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
1389 (allocate_misc): Remove prototype.
1390 (format_save_value): New prototype.
1391 * alloc.c (allocate_misc): Revert back to static.
1392 (format_save_value): New function to build Lisp_Save_Value
1393 object with the specified internal structure.
1394 (make_save_value): Reimplement using format_save_value.
1395 * editfns.c (save_excursion_save): Use format_save_value.
1396 (save_excursion_restore): Use XSAVE_OBJECT.
1398 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1400 Avoid needless casts with XSAVE_POINTER.
1401 * alloc.c (mark_object) [GC_MARK_STACK]:
1402 * dired.c (directory_files_internal_unwind):
1403 * fileio.c (do_auto_save_unwind):

1433 * editfns.c (save_excursion_save): Pack everything within
1434 Lisp_Save_Value and so avoid xmalloc.
1435 (save_excursion_restore): Adjust to match new layout. Use free_misc
1436 because we do not allocate extra memory any more. Add eassert.
1437 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1438 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1450 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1452 Fix SIGDANGER handlers, for AIX (Bug#13408).
1453 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1454 Move handlers here from emacs.c; they were out of place.
1456 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1458 * xterm.c (syms_of_xterm): Adjust documentation for

1505 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1507 Avoid unnecessary byte position calculation for the gap movement.
1508 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1519 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1521 * term.c (init_tty): Use them instead of rolling our own code.
1522 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1523 switches from 'signal' to 'pthread_sigmask', which is safer in
1524 multithreaded applications.
1525 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1526 which has already arranged for that.
1527 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1528 This is the main part of the bug fix.

1540 predicate, which is how it's really used now. Adjust comment.
1541 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1542 * buffer.c (buffer_slot_type_mismatch): Remove.
1543 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1544 predicate. Adjust comment.

1547 left-margin-width, right-margin-width, left-fringe-width,
1548 right-fringe-width, scroll-bar-width and buffer-display-count.
1549 Use Qstringp for default-directory, buffer-file-name,
1550 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1551 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

1571 * coding.c (coding_alloc_by_making_gap): Use it.
1572 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1596 trailing dash is properly added.
1598 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1600 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1601 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1602 digits for buffer positions, before misalignment starts.
1603 Display "0" for integer "object" field.
1604 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1605 Display the newline glyph more unambiguously.
1607 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1609 * nsterm.m (ns_draw_underwave):
1610 * w32term.c (w32_draw_underwave):
1611 * xterm.c (x_draw_underwave): Make underwave look more triangular
1612 and also degrade gracefully for small fonts. (Bug#13000)
1614 * nsterm.m (ns_draw_text_decoration):
1615 * w32term.c (x_draw_glyph_string):
1616 * xterm.c (x_draw_glyph_string): Don't use previous underline
1617 thickness and position if previous underline type is underwave.

1637 * term.c (tty_ins_del_lines):
1638 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1639 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1641 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1643 * w32.c (unsetenv): Set up the string passed to _putenv
1645 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1646 for the bug this caused.
1648 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1650 * coding.c (Qmac): Now static.
1652 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1654 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1655 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1662 by TOOLBAR_TOP_WIDGET.
1663 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1664 Check toolbar_is_packed.
1665 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1666 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1667 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1669 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1670 (xg_update_menubar): Update title only if
1671 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1672 (xg_update_submenu): Skip tearoff only if
1673 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1674 (xg_initialize): Initialize xg_detached_menus only if
1675 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1677 * xterm.h (struct x_output): Surround handlebox_widget with
1678 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1679 toolbar_in_hbox is bool.
1681 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1683 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1684 (LIBS_GNUSTEP): Define.
1685 (LIBES): Add $(LIBS_GNUSTEP).
1686 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1688 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1690 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1691 continuation glyph on a TTY with an indication of an empty line.
1694 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1696 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1697 file's SELinux context or ACLs successfully set, nil otherwise.
1699 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1701 * w32proc.c (reader_thread): Avoid passing NULL handles to
1702 SetEvent and WaitForSingleObject.
1704 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1706 Port EXTERNALLY_VISIBLE to Clang 3.2.
1707 * conf_post.h (__has_attribute): New macro.
1708 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1710 2012-12-27 Glenn Morris <rgm@gnu.org>
1712 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1713 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1715 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1717 * fileio.c (file_name_as_directory, directory_file_name):
1718 Accept an additional argument MULTIBYTE to indicate whether the input C
1719 came from a multibyte or a unibyte Lisp string; all callers
1720 adjusted. Don't assume the input string is always multibyte.
1722 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1723 don't ENCODE_FILE them, and return a unibyte string if the input
1725 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1726 don't assume the input strings will always be multibyte. If the
1727 input strings are multibyte, decode strings obtained from C
1730 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1732 * lisp.h (toplevel): Add two notices to the comment about
1733 defining a new Lisp data type.

1737 * alloc.c (valid_lisp_object_p): Adjust comment.
1739 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1741 * keyboard.c (record_asynch_buffer_change): Initialize an event
1742 only if it's really needed.
1743 * frame.h (enum output_method): Remove output_mac member since
1744 it's a leftover from the deleted code.
1745 * frame.c (Fframep): Adjust user here ...
1746 * terminal.c (Fterminal_live_p): ... and here.
1747 * coding.c (Qmac): Now here because it's only used to denote
1748 end-of-line encoding type.
1749 (syms_of_coding): DEFSYM it.
1750 * frame.h (Qmac): Remove duplicated declaration.
1752 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1754 * window.c (select_window_1): Now static, since it's used only here.
1756 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1758 * window.c (window_body_cols): Subtract display margins from the
1759 window body width on TTYs as well. See
1760 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1761 for the original report.
1763 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1765 * xdisp.c (redisplay_window): Remove inner local variable
1766 because the outer shadowed one has the same meaning.
1767 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1769 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1770 (xg_create_tool_bar): Adjust users.
1772 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1774 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1775 * buffer.c (Fget_buffer_create): Use it to set compact field of
1776 struct buffer_text to avoid accessing an uninitialized value
1777 when compact_buffer is called for the first time.
1778 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1779 (Fset_buffer_modified_p): Use buffer_window_count to check
1780 whether the buffer is displayed in some window.
1781 * xdisp.c (message_dolog): Likewise.
1783 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1785 * w32.c (acl_set_file): If setting the file security descriptor
1786 fails, and the new DACL is identical to the existing one, silently
1787 return success. This fixes problems for users backing up their
1788 own files without having the necessary privileges for setting
1789 security descriptors.
1791 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1793 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1794 after WaitForSingleObject returns normally. This expedites reader
1795 thread shutdown when delete_child triggers it.
1796 (reap_subprocess): More accurate commentary for why we call
1797 delete_child only when cp->fd is negative.
1799 * w32.c (sys_close): Do not call delete_child on a subprocess
1800 whose handle is not yet closed. Instead, set its file descriptor
1801 to a negative value, so that reap_subprocess will call
1802 delete_child on that subprocess when its SIGCHLD arrives.
1803 This avoids closing handles used for communications between sys_select
1804 and reader_thread, which doesn't give sys_select a chance to
1805 notice that the process exited and invoke the SIGCHLD handler for
1808 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1810 * nsfns.m (Fns_do_applescript): Run event loop until script has
1811 been executed (Bug#12969).

1819 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1821 * w32term.c (w32fullscreen_hook): New function.
1822 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1824 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1826 * fileio.c (Finsert_file_contents): Doc fix.
1828 * w32proc.c (new_child, delete_child, find_child_pid): For a
1829 subprocess, consider its slot being in use as long as its process
1830 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1831 slot when a new process is started immediately after killing
1832 another one, without waiting enough time for the first process to
1833 be reaped and resources allocated for it be orderly freed.
1835 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1837 2012-12-21 Chong Yidong <cyd@gnu.org>
1839 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1841 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1843 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1845 * w32.c (get_name_and_id): Always pass NULL as the first argument
1846 of lookup_account_sid. Avoids crashes with UNC file names that
1847 refer to DFS domains, not to specific machine names. (Bug#12621)
1848 Remove now unused argument FNAME; all callers changed.
1849 (get_file_owner_and_group): Remove now unused argument FNAME; all
1852 2012-12-21 Chong Yidong <cyd@gnu.org>
1854 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1855 error for invalid chars, don't check for a nil return value.
1857 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1859 Avoid calls to CHAR_TO_BYTE if byte position is known.
1860 * editfns.c (make_buffer_string_both): Use move_gap_both.
1861 (Fbuffer_string): Use make_buffer_string_both.

1864 (buf_bytepos_to_charpos): Likewise.
1865 (charpos_to_bytepos): Remove.
1866 * fileio.c (Finsert_file_contents): Use move_gap_both.
1867 * search.c (Freplace_match): Likewise.
1868 * process.c (process_send_region): Likewise. Use convenient
1869 names for byte positions.
1870 * lisp.h (charpos_to_bytepos): Remove prototype.
1871 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1872 * insdel.c (move_gap): Likewise.

1943 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1945 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1946 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1947 for some of that bug's symptoms can now cause Emacs to abort.
1948 Remove the workaround.
1949 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1950 The bug that caused SIGCHLD to get lost has been fixed, and the

2031 * dired.c (Ffile_attributes) [WINDOWSNT]:
2032 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2033 owner and group information from 'lstat'.

2037 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2038 as that confuses set-auto-coding, so insist on the head-read

2067 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2069 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2070 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2071 Remove unnecessary S_ISLNK test, as (contra the comments) this
2072 function can't copy symlinks. Improve quality of error message
2073 when attempting to copy files that are neither regular files nor

2092 * inotify.c (inotify_callback): Generate an Emacs event for every
2093 incoming inotify event.

2352 (deleted_pid_list, Fdelete_process, create_process)
2353 (record_child_status_change, handle_child_signal, deliver_child_signal)
2354 (init_process_emacs, syms_of_process):
2355 Assume SIGCHLD is defined.
2356 (parse_signal): Remove. All uses removed.
2357 (abbr_to_signal): New static function.
2358 (Fsignal_process): Use it to convert signal names to ints.
2359 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2360 kill (getpgrp (), ...).
2361 (emacs_sigaction_init): Assume SIGCHLD is defined.
2362 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2363 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2364 * syssignal.h (EMACS_KILLPG): Remove.
2365 All uses replaced by 'kill' with a negative pid.
2366 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2367 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2369 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2371 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2372 This will cause a production Emacs to dump core instead of
2375 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2377 * frame.c (make_frame): Do not set window's buffer to t.
2378 * window.c (Fsplit_window_internal): Likewise. Previously it was
2379 used to indicate that the window is being set up. Now we use
2380 set_window_buffer for all new windows, so the condition in ...
2381 (Fset_window_buffer): ... is always true and can be removed.
2383 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2385 Convenient macro to check whether the buffer is hidden.
2386 * buffer.h (BUFFER_HIDDEN_P): New macro.
2387 * frame.c (make_frame): Use it. Adjust comment.
2388 * buffer.c (candidate_buffer): New function.
2389 (Fother_buffer, other_buffer_safely): Use it.
2391 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2393 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2394 if the child process is still running. Instead, exit the wait
2395 loop and return zero. (Bug#13086)
2397 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2399 * frame.h (x_char_width, x_char_height): Remove prototypes.
2400 * w32term.h (x_char_width, x_char_height): Likewise.
2401 * xfns.c (x_char_width, x_char_height): Remove.

2410 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2412 Fix a recently-introduced delete-process race condition.
2413 * callproc.c, process.h (record_kill_process):
2414 New function, containing part of the old call_process_kill.
2415 (call_process_kill): Use it.
2416 This does not change call_process_kill's behavior.
2417 * process.c (Fdelete_process): Use record_kill_process to fix a
2418 race condition that could cause Emacs to lose track of a child.
2420 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2422 Avoid code duplication between prev_frame and next_frame.
2423 * frame.c (candidate_frame): New function. Add comment.
2424 (prev_frame, next_frame): Use it. Adjust comment.
2426 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2428 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2429 fails, signal an error instead of continuing with an empty
2431 Encode expanded temp file pattern before passing it to mkstemp or
2434 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2435 Encode the file name before passing it to dostounix_filename, in
2436 case it will downcase it (under w32-downcase-file-names).
2439 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2441 Minor call-process cleanups.
2442 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2443 at the same time as other platforms, to simplify analysis.
2444 No need for fd0_volatile since we have synch_process_fd.
2445 Avoid needless emacs_close; arg is always negative.
2447 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2449 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2452 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2454 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2455 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2456 and mouse_face_hidden members to a bitfields.
2457 * frame.h (struct frame): Remove set-but-not-used space_width member.
2458 (FRAME_SPACE_WIDTH): Remove.
2459 * nsterm.m, w32term.c, xterm.c: Adjust users.
2460 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2461 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2462 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2463 members to a bitfields.
2465 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2467 Don't let call-process be a zombie factory (Bug#12980).
2468 Fixing this bug required some cleanup of the signal-handling code.
2469 As a side effect, this change also fixes a longstanding rare race
2470 condition whereby Emacs could mistakenly kill unrelated processes,
2471 and it fixes a bug where a second C-g does not kill a recalcitrant
2472 synchronous process in GNU/Linux and similar platforms.
2473 The patch should also fix the last vestiges of Bug#9488,
2474 a bug which has mostly been fixed on the trunk by other changes.
2475 * callproc.c, process.h (synch_process_alive, synch_process_death)
2476 (synch_process_termsig, sync_process_retcode):
2477 Remove. All uses removed, to simplify analysis and so that
2478 less consing is done inside critical sections.
2479 * callproc.c (call_process_exited): Remove. All uses replaced
2480 with !synch_process_pid.
2481 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2482 These take the role of what used to be in unwind-protect arg.
2484 (block_child_signal, unblock_child_signal):
2485 New functions, to avoid races that could kill innocent-victim processes.
2486 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2487 (call_process_kill): Record killed processes as deleted, so that
2488 zombies do not clutter up the system. Do this inside a critical
2489 section, to avoid a race that would allow the clutter.
2490 (call_process_cleanup): Fix code so that the second C-g works again
2491 on common platforms such as GNU/Linux.
2492 (Fcall_process): Create the child process in a critical section,
2493 to fix a race condition. If creating an asynchronous process,
2494 record it as deleted so that zombies do not clutter up the system.
2495 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2496 light of these changes. Omit unnecessary call to emacs_close
2497 before failure, as the unwind-protect code does that.
2498 * callproc.c (call_process_cleanup):
2499 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2500 * process.c (record_deleted_pid): New function, containing
2501 code refactored out of Fdelete_process.
2502 (Fdelete_process): Use it.
2503 (process_status_retrieved): Remove. All callers changed to use
2504 child_status_change.
2505 (record_child_status_change): Remove, folding its contents into ...
2506 (handle_child_signal): ... this signal handler. Now, this
2507 function is purely a handler for SIGCHLD, and is not called after
2508 a synchronous waitpid returns; the synchronous code is moved to
2509 wait_for_termination. There is no need to worry about reaping
2510 more than one child now.
2511 * sysdep.c (get_child_status, child_status_changed): New functions.
2512 (wait_for_termination): Now takes int * status and bool
2513 interruptible arguments, too. Do not record child status change;
2514 that's now the caller's responsibility. All callers changed.
2515 Reimplement in terms of get_child_status.
2516 (wait_for_termination_1, interruptible_wait_for_termination):
2517 Remove. All callers changed to use wait_for_termination.
2518 * syswait.h: Include <stdbool.h>, for bool.
2519 (record_child_status_change, interruptible_wait_for_termination):
2521 (record_deleted_pid, child_status_changed): New decls.
2522 (wait_for_termination): Adjust to API changes noted above.
2524 * bytecode.c, lisp.h (Qbytecode): Remove.
2525 No longer needed after 2012-11-20 interactive-p changes.
2527 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2529 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2530 the scroll margin, move point outside the margin. (Bug#13055)
2532 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2534 * gtkutil.c (my_log_handler): New function.
2535 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2537 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2539 * lisp.h (modify_region): Rename to...
2540 (modify_region_1): ...new prototype.
2541 * textprop.c (modify_region): Now static. Adjust users.
2542 * insdel.c (modify_region): Rename to...
2543 (modify_region_1): ...new function to work with current buffer.
2544 Adjust comment and users. Use true and false for booleans.
2546 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2548 * alloc.c (free_save_value): New function.
2549 (safe_alloca_unwind): Use it.
2550 * lisp.h (free_save_value): New prototype.
2551 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2553 (save_excursion_restore): Adjust to match saved data structure.
2554 Use free_save_value to offload some work from GC. Drop obsolete
2557 2012-12-03 Chong Yidong <cyd@gnu.org>
2559 * fileio.c (Vauto_save_list_file_name): Doc fix.
2561 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2563 * w32fns.c: Remove prototype of atof.
2564 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2566 (file_dialog_callback): Make it UINT_PTR.
2568 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2571 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2572 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2575 2012-12-03 Glenn Morris <rgm@gnu.org>
2577 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2579 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2581 Fix xpalloc confusion after memory is exhausted.
2582 * alloc.c (xpalloc): Comment fix.
2583 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2584 and signals an error, do not clear charset_table_size, as
2585 charset_table is still valid.
2586 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2588 Use execve to avoid need to munge environ (Bug#13054).
2589 * callproc.c (Fcall_process):
2590 * process.c (create_process):
2591 Don't save and restore environ; no longer needed.
2592 * callproc.c (child_setup):
2593 Use execve, not execvp, to preserve environ.
2595 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2597 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2599 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2601 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2602 display for sliced images (Bug#10500).
2604 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2606 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2608 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2609 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2611 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2613 * xdisp.c (window_outdated): Remove eassert since it hits
2614 some suspicious corner cases (see Bug#13007 and Bug#13012).
2615 (mode_line_update_needed): New function.
2616 (redisplay_internal, redisplay_window): Use it.
2617 (ensure_selected_frame): New function.
2618 (redisplay_internal, unwind_redisplay): Use it.
2619 (redisplay_internal): Move comment about buffer_shared...
2620 (buffer_shared_and_changed): ...near to its real use.
2622 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2624 * callproc.c (Fcall_process): Don't misreport vfork failure.
2626 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2628 * callproc.c (Fcall_process): Fix vfork portability problems.
2629 Do not assume that fd[0], count, filefd, and save_environ survive
2630 vfork. Fix bug whereby wrong errno value could be reported for
2631 pipe failure. Some minor cleanups, too, as follows. Move buf and
2632 bufsize to the context where they're needed. Change new_argv to
2633 be of type char **, as this is more convenient and avoids casts.
2634 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2635 Now local constants, not macros.
2637 2012-11-18 Kenichi Handa <handa@gnu.org>
2639 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2640 for the variable "f".
2642 2012-11-13 Kenichi Handa <handa@gnu.org>
2644 * font.c (font_unparse_xlfd): Exclude special characters from the
2645 generating XLFD name.
2647 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2649 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2650 * dired.c (stat_uname, stat_gname):
2651 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2653 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2660 * lread.c (readbyte_from_file): Assume EINTR is defined.
2661 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2662 Assume EIO and EAGAIN are defined.
2663 * unexcoff.c (write_segment): Assume EFAULT is defined.
2665 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2667 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2670 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2671 highlighting on the frame was cleared. Prevents assertion
2672 violations when repeatedly clicking on the "Top" link of the
2673 "bread-crumbs" in Info buffers.
2675 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2677 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2679 2012-11-24 Ken Brown <kbrown@cornell.edu>
2681 * keyboard.c (HAVE_MOUSE):
2682 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2683 were always defined.
2685 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2687 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2688 between bpos_covered and bpos_max. This fixes cursor display when
2689 several display strings follow each other.
2691 * .gdbinit (pgx): If the glyph's object is a string, display the
2692 pointer to string data, rather than the value of the string object
2693 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2695 * indent.c (Fvertical_motion): If the starting position is covered
2696 by a display string, return to one position before that, to avoid
2697 overshooting it inside move_it_to. (Bug#12930)
2699 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2701 * frame.h (struct frame): Remove display_preempted member

2704 * w32menu.c (pending_menu_activation): Remove since not
2706 (set_frame_menubar): Adjust user.
2707 * w32term.h (struct x_output): Drop outdated #if 0 code.
2708 (struct w32_output): Use bitfields for explicit_parent,
2709 asked_for_visible and menubar_active members.
2710 Drop unused pending_menu_activation member.
2711 * xterm.h (struct x_output): Drop outdated #if 0 code.
2712 Use bitfields for explicit_parent, asked_for_visible,
2713 has_been_visible and net_wm_state_hidden_seen members.
2715 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2717 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2718 of a literal "/". (Bug#12955)
2719 (gl-stamp): Invoke fc.exe directly, not through cmd.
2721 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2723 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2724 * dired.c: Assume HAVE_DIRENT_H.
2725 (NAMLEN): Remove, replacing with ...
2726 (dirent_namelen): New function. All uses changed. Use the GNU macro
2727 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2728 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2729 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2730 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2732 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2733 * ndir.h: Rename to ../nt/inc/dirent.h.
2734 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2735 Do not include <dirent.h>; no longer needed.
2736 * w32.c: Include <dirent.h> rather than "ndir.h".
2738 2012-11-23 Chong Yidong <cyd@gnu.org>
2740 * xftfont.c (xftfont_open): Remove duplicate assignment.
2742 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2744 * alloc.c (Fgarbage_collect): Unblock input after clearing
2745 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2746 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2747 * msdos.c (IT_frame_up_to_date): Use it here...
2748 * w32term.c (w32_frame_up_to_date): ...here...
2749 * xterm.c (XTframe_up_to_date): ...and here...
2750 * nsterm.m (ns_frame_up_to_date): ...but not here.
2751 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2753 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2754 Do not check whether GC is in progress.
2756 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2758 * xdisp.c (window_buffer_changed): New function.
2759 (update_menu_bar, update_tool_bar): Use it to
2760 simplify large 'if' statements.
2761 (redisplay_internal): Generalize commonly used
2762 'tail' and 'frame' local variables.
2764 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2766 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2767 with Windows system header.
2769 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2771 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2772 * alloc.c: Assume unistd.h exists.
2773 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2774 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2775 (getwd) [USG]: Remove; no longer needed.
2776 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2777 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2778 * w32.h (getcwd): Remove decl.
2780 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2782 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2783 Make it set selected_window as well.
2784 (update_tool_bar): Use it.
2786 2012-11-21 Ken Brown <kbrown@cornell.edu>
2788 * emacs.c (main): Set the G_SLICE environment variable for all
2789 Cygwin builds, not just GTK builds. See
2790 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2792 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2794 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2795 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2796 Define for the MSVC compiler.
2798 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2800 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2801 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2802 dostounix_filename. Prevents crashes down the road, because
2803 dostounix_filename assumes it gets a unibyte string.

2812 * eval.c (Fcommandp): Ignore Qunbound.
2813 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2814 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2815 Test NILP rather than Qunbound.
2816 (Ffmakunbound): Set to Qnil.
2817 (Fsymbol_function): Never signal an error.
2818 (Finteractive_form): Ignore Qunbound.
2820 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2822 * eval.c (interactive_p): Remove no-longer-used decl.
2824 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2826 * xdisp.c (buffer_shared): Adjust comment.
2827 (buffer_shared_and_changed): New function.

2829 decide whether all windows or frames should be updated.
2830 (window_outdated): New function.
2831 (text_outside_line_unchanged_p, redisplay_window): Use it.
2832 (redisplay_internal): Likewise. Fix indentation.
2834 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2836 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2837 (syms_of_eval): Remove corresponding defsubr.
2838 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2840 2012-11-19 Daniel Colascione <dancol@dancol.org>
2842 * w32fns.c (Fx_file_dialog):
2843 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2844 cygwin_convert_file_name*.
2846 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2847 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2849 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2851 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2853 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2855 * w32select.c: Include w32common.h before w32term.h, so that
2856 windows.h gets included before w32term.h uses some of its
2857 features, see below.
2859 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2861 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2863 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2865 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2867 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2868 (ns_select): Return at once if events are held (Bug#12834).
2870 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2872 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2873 Needed following 2012-10-20 change. (Bug#12902)
2875 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2877 * w32proc.c (waitpid): Remove unused label get_result.
2879 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2881 * makefile.w32-in (SYSWAIT_H): New macro.
2882 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2883 ($(BLD)/sysdep.$(O)): Update dependencies.
2885 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2887 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2888 * callproc.c (relocate_fd): Assume F_DUPFD.
2889 * emacs.c, term.c (O_RDWR): Remove.
2890 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2891 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2892 * nsterm.m: Assume <fcntl.h> exists.
2893 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2894 (create_pty, Fmake_network_process, server_accept_connection)
2895 (wait_reading_process_output, init_process_emacs):
2897 (wait_reading_process_output): Put in a special case for WINDOWSNT
2898 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2899 It's not clear this is needed, but it's a more-conservative change.
2900 (create_process): Assume FD_CLOEXEC.
2901 (create_process, create_pty): Assume O_NOCTTY.
2902 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2903 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2904 Omit if not DOS_NT, since F_GETFL is not defined there.
2905 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2906 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2908 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2909 lack it, since gnulib guarantees this.
2910 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2912 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2914 * w32.c (faccessat): Pretend that directories have the execute bit
2915 set. Emacs expects that, e.g., in files.el:cd-absolute.
2917 * w32proc.c (create_child): Don't clip the PID of the child
2918 process to fit into an Emacs integer, as this is no longer a
2920 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2921 reaping only the process specified by PID argument, if that is
2922 positive. Use PID instead of dead_child to know which process to
2923 reap. Wait for the child to die only if WNOHANG is not in
2925 (sys_select): Don't set dead_child.
2927 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2928 as it is no longer needed.
2930 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2932 (record_child_status_change): Remove the setting of
2933 record_at_most_one_child for the !WNOHANG case.
2935 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2937 Fix problems in ns port found by static checking.
2938 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2939 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2940 not to process group.
2941 (ns_select): Use emacs_write, not write, as that's more robust
2942 in the presence of signals.
2943 (fd_handler:): Check for read errors.
2945 2012-11-16 Glenn Morris <rgm@gnu.org>
2947 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2949 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2951 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2953 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2955 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2956 use the same value of thread handle.
2957 (start_timer_thread): If the timer thread exited (due to error),
2958 clean up by closing the two handles it used. Duplicate the caller
2959 thread's handle here, so it gets duplicated only once, when
2960 launching the timer thread. Set priority of the timer thread, not
2962 (getitimer): Don't duplicate the caller thread's handle here.
2965 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2967 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2970 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2972 Remove no-longer-used pty_max_bytes variable.
2973 * process.c (pty_max_bytes): Remove; unused.
2974 (send_process): Do not set it.
2976 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2978 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2979 Update dependencies.
2981 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2983 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2984 This follows up on the 2012-09-29 patch that removed indirection
2985 for the 'function' field. Reported by Sergey Vinokurov in
2986 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2988 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2990 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2991 different name, as the MS runtime does not have such a function,
2992 and probably never will.) All callers changed. Ignore DIRFD
2993 value if PATH is an absolute file name, to match Posix spec
2994 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2997 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2999 * xdisp.c (echo_area_display, redisplay_internal):
3000 Omit redundant check whether frame_garbaged is set.
3002 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3004 Use faccessat, not access, when checking file permissions (Bug#12632).
3005 This fixes a bug that has been present in Emacs since its creation.
3006 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3007 which must set some sort of record. (Torek's bug report was against
3008 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3009 same common flaw.) See Torek's Usenet posting
3010 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3011 Posted: Fri Apr 8 14:18:56 1983.
3012 * Makefile.in (LIB_EACCESS): New macro.
3014 * callproc.c (init_callproc):
3015 * charset.c (init_charset):
3016 * fileio.c (check_existing, check_executable, check_writable)
3018 * lread.c (openp, load_path_check):
3019 * process.c (allocate_pty):
3021 Use effective UID when checking permissions, not real UID.
3022 * callproc.c (init_callproc):
3023 * charset.c (init_charset):
3024 * lread.c (load_path_check, init_lread):
3025 Test whether directories are accessible, not merely whether they exist.
3026 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3027 * fileio.c (check_existing, check_executable, check_writable)
3029 Use symbolic names instead of integers for the flags, as they're
3031 (check_writable): New arg AMODE. All uses changed.
3032 Set errno on failure.
3033 (Ffile_readable_p): Use faccessat, not stat + open + close.
3034 (Ffile_writable_p): No need to call check_existing + check_writable.
3035 Just call check_writable and then look at errno. This saves a syscall.
3036 dir should never be nil; replace an unnecessary runtime check
3037 with an eassert. When checking the parent directory of a nonexistent
3038 file, check that the directory is searchable as well as writable, as
3039 we can't create files in unsearchable directories.
3040 (file_directory_p): New function, which uses 'stat' on most platforms
3041 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3042 (Ffile_directory_p, Fset_file_times): Use it.
3043 (file_accessible_directory_p): New function, which uses a single
3044 syscall for efficiency.
3045 (Ffile_accessible_directory_p): Use it.
3046 * xrdb.c (file_p): Use file_directory_p.
3047 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3048 * lread.c (openp): When opening a file, use fstat rather than
3049 stat, as that avoids a permissions race. When not opening a file,
3050 use file_directory_p rather than stat.
3051 (dir_warning): First arg is now a usage string, not a format.
3052 Use errno. All uses changed.
3053 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3054 that merely introduced a race.
3055 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3056 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3057 and similarly for the other O_* flags.
3058 * w32.c (sys_faccessat): Rename from sys_access and switch to
3059 faccessat's API. All uses changed.
3060 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3061 (magic_db): Rename from magic_file_p.
3062 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3063 char *, so that we don't have to test for file existence
3064 separately from opening the file for reading. This removes a race
3065 fixes a permission-checking problem, and simplifies the code.
3067 (file_p): Remove; no longer needed.
3069 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3071 Omit glyphs initialization at startup.
3072 * dispnew.c (glyphs_initialized_initially_p): Remove.
3073 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3074 (Fredraw_frame): Move actual code from here...
3075 (redraw_frame): ...to here. Add eassert. Adjust comment.
3076 (Fredraw_display): Use redraw_frame.
3077 * xdisp.c (clear_garbaged_frames): Likewise.
3079 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3081 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3082 passed to pint2str and pint2hrstr to be at most the size of the
3083 frame's decode_mode_spec_buffer. This avoids crashes with very
3084 large values of FIELD_WIDTH argument to decode_mode_spec.
3087 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3089 Fix a race with verify-visited-file-modtime (Bug#12863).
3090 Since at least 1991 Emacs has ignored an mtime difference of no
3091 more than one second, but my guess is that this was to work around
3092 file system bugs that were fixed long ago. Since the race is
3093 causing problems now, let's remove that code.
3094 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3095 whose time stamp is off by no more than a second. Insist that the
3096 file time stamps match exactly.
3098 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3100 * frame.h (struct frame): Convert external_tool_bar member to
3101 1-bit unsigned bitfield.
3102 * termhooks.h (struct terminal): Remove mouse_moved member since
3103 all users are long dead. Adjust comment on mouse_position_hook.
3105 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3107 Simplify by using FOR_EACH_FRAME here and there.
3108 * frame.c (next_frame, prev_frame, other_visible_frames)
3109 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3110 * w32term.c (x_window_to_scroll_bar): Likewise.
3111 * window.c (window_list): Likewise.
3112 * xdisp.c (x_consider_frame_title): Likewise.
3113 * xfaces.c (Fdisplay_supports_face_attributes_p): Likewise.
3114 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3115 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3116 * xmenu.c (menubar_id_to_frame): Likewise.
3117 * xselect.c (frame_for_x_selection): Likewise.
3118 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3119 (x_window_to_menu_bar): Likewise.
3120 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3122 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3124 * data.c (Qdefalias_fset_function): Now static.
3126 Another tweak to vectorlike_header change.
3127 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3128 Remove, and replace all uses with ...
3129 (next_in_free_list, set_next_in_free_list):
3130 New functions, which respect C's aliasing rules better.
3132 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3134 * window.c (list4i): Rename from 'quad'. All uses changed.
3135 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3137 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3139 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3140 warning about mixing declarations and code in ISO C90.
3142 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3144 * window.c (Fsplit_window_internal): Set combination limit of
3145 new parent window to t iff Vwindow_combination_limit is t;
3146 fixing a regression introduced with the change from 2012-09-22.
3147 (Fset_window_combination_limit): Fix doc-string.
3149 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3151 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3152 amount when the scroll margins are too large. When scrolling
3153 backwards in the buffer, give up if cannot reach point or the
3154 scroll margin within a reasonable number of screen lines.
3155 Fixes point position in window under scroll-up/down-aggressively when
3156 point is positioned many lines beyond the window top/bottom.
3159 * ralloc.c (relinquish): If real_morecore fails to return memory
3160 to the system, don't crash; instead, leave the last heap
3161 unchanged and return. (Bug#12774)
3163 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3165 * lisp.h (AUTOLOADP): New macro.
3166 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3167 * data.c (Ffset): Remove special ad-advice-info handling.
3168 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3170 (Finteractive_form): Simplify.
3171 (Fquo): Don't insist on having at least 2 arguments.
3172 (Qdefalias_fset_function): New var.
3174 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3176 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3180 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3182 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3184 Fix recently introduced crash on MS-Windows (Bug#12839).
3185 * w32term.h (struct scroll_bar): Use convenient header.
3186 (SCROLL_BAR_VEC_SIZE): Remove.
3187 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3189 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3191 Tweak last vectorlike_header change.
3192 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3193 vectorlike object on the free list. This is introduced to avoid
3194 some (but not all) pointer casting and aliasing problems, see
3195 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3196 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3198 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3200 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3202 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3203 been removed, so remove them here also.
3205 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3207 * doc.c (Fdocumentation): Handle new property
3208 dynamic-docstring-function to replace the old ad-advice-info.
3210 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3212 * fns.c (Qeql, hashtest_eq): Now static.
3214 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3216 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3217 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3218 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3219 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3221 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3223 Use same hash function for hashfn_profiler as for hash_string etc.
3224 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3225 * lisp.h (sxhash_combine): New inline function, with the contents
3226 of the old SXHASH_COMBINE.
3227 * profiler.c (hashfn_profiler): Use it, instead of having a
3228 special hash function containing a comparison that always yields 1.
3230 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3232 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3233 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3234 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3237 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3239 * image.c (xpm_make_color_table_h): Fix compiler error because
3240 make_hash_table changed.
3242 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3244 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3246 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3248 Use ad-hoc comparison function for the profiler's hash-tables.
3249 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3250 (make_log): Use them.
3251 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3252 call Fequal any more.

3260 (cmpfn_eql, cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
3261 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3262 (hash_lookup, hash_remove_from_table): Move assertion checking of
3263 hashfn result here. Check hash-equality before calling cmpfn.
3264 (Fmake_hash_table): Adjust call to make_hash_table.
3265 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3266 (syms_of_fns): Initialize them.

3271 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
3273 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3275 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3276 value of w32-scroll-lock-modifier is neither nil nor one of the
3277 known key modifiers. (Bug#12806)
3279 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3281 Shrink struct vectorlike_header to the only size field.
3282 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3284 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3285 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3286 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3287 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3288 information from the vector header. Adjust comment.

3298 (enum mem_type): Adjust comment.
3299 (NEXT_IN_FREE_LIST): New macro.
3300 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3301 (Fmake_bool_vector): Likewise.
3302 (struct large_vector): New type to represent allocation unit for
3303 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3304 (large_vectors): Change type to struct large_vector.
3305 (allocate_vector_from_block): Simplify.
3306 (PSEUDOVECTOR_NBYTES): Replace with...
3307 (vector_nbytes): ...new function. Adjust users.
3308 (sweep_vectors): Adjust processing of large vectors.
3309 (allocate_vectorlike): Likewise.
3310 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3311 Add easserts. Adjust XSETPVECTYPESIZE usage.
3312 (allocate_buffer): Use BUFFER_PVEC_INIT.
3313 (live_vector_p): Adjust to match large vector.
3314 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3315 * buffer.h (struct buffer): Add next member.
3316 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3318 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3319 * fns.c (internal_equal): Adjust to match enum pvec_type change.

3324 (xvecsize): New command.
3326 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3328 * keyboard.c (event_to_kboard): Do not dereference
3329 frame_or_window field of SELECTION_REQUEST_EVENT
3330 and SELECTION_CLEAR_EVENT events (Bug#12814).
3331 * xterm.h (struct selection_input_event): Adjust comment.
3333 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3335 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3336 such as Scroll Lock, if the respective keys are treated as
3337 function keys, not as modifiers. This avoids destroying non-ASCII
3338 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3340 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3342 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3344 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3346 Restore some duplicate definitions (Bug#12814).
3347 This undoes part of the 2012-11-03 changes. Some people build
3348 with plain -g rather than with -g3, and they need the duplicate
3349 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3350 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3351 Define as macros, as well as as enums or as constants.
3353 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3355 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3356 to keypad keys (Bug#12816).
3358 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3360 Minor adjustments of recently-changed frame functions.
3361 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3362 known to be a frame (we're in the FRAMEP branch).
3363 * lisp.h (Qframep): Remove decl. frame.h declares this.
3364 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3365 since they're meant for Lisp fixnum values.
3367 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3369 * window.c (Fwindow_combination_limit): Revert to the only
3370 required argument and adjust docstring as suggested in
3371 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3372 by Martin Rudalics <rudalics@gmx.at>.
3374 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3376 Widely used frame validity and checking functions.
3377 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3378 * frame.c (decode_live_frame, decode_any_frame): New functions.
3379 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3380 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3381 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3382 (Fframe_pointer_visible_p): Use decode_any_frame.

3384 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3385 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3386 (Fframe_focus): Likewise. Allow zero number of arguments.
3388 (frame_buffer_list, frame_buffer_predicate): Remove.
3389 * lisp.h (frame_buffer_predicate): Remove prototype.
3390 * buffer.c (Fother_buffer): Use decode_any_frame.
3391 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3392 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3393 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3394 (Fclose_font, Ffont_info): Use decode_live_frame.
3395 * fontset.c (check_fontset_name): Likewise.
3396 * terminal.c (Fframe_terminal): Likewise.
3397 * w32fns.c (check_x_frame): Likewise.
3398 * window.c (Fminibuffer_window, Fwindow_at)
3399 (Fcurrent_window_configuration): Likewise.
3400 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3401 Likewise. Allow zero number of arguments. Adjust docstring.
3402 * dispnew.c (Fredraw_frame): Likewise.
3403 * xfaces.c (frame_or_selected_frame): Remove.
3404 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3405 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3406 (Fframe_face_alist): Use decode_live_frame.
3407 * xfns.c (check_x_frame): Likewise.
3409 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3411 * window.c (quad): New function.
3412 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3413 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3414 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3415 (Fwindow_line_height): Use it.
3416 (Fwindow_fringes): Use list3.
3417 (Fwindow_scroll_bars): Use list4.
3418 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3419 (Fwindow_combination_limit): Allow zero number of arguments.
3421 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3423 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3425 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3426 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3427 file descriptor 2 for standard error. (Bug#12805)
3429 2012-11-05 Chong Yidong <cyd@gnu.org>
3431 * process.c (wait_reading_process_output): Revert previous change.
3433 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3435 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3436 This removes code that has been obsolete since around 1990.
3437 * callproc.c (Fcall_process):
3439 * process.c (create_process):
3440 * term.c (dissociate_if_controlling_tty):
3441 Assume setsid exists.
3442 * callproc.c (child_setup): Assume setpgid exists and behaves as
3443 per POSIX.1-1988 or later.
3444 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3445 * emacs.c (shut_down_emacs):
3446 * sysdep.c (sys_suspend, init_foreground_group):
3447 Assume getpgrp behaves as per POSIX.1-1998 or later.
3448 * msdos.c (setpgrp): Remove.
3449 (tcgetpgrp, setpgid, setsid): New functions.
3450 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3451 * term.c (no_controlling_tty): Remove; unused.
3452 * w32proc.c (setpgrp): Remove.
3453 (setsid, tcgetpgrp): New functions.
3455 Simplify by assuming __fpending.
3456 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3457 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3458 Do not assume that __fpending's result fits in int.
3460 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3462 Remove EMACS_OUTQSIZE+sleep hack.
3463 * dispnew.c (update_frame_1): Remove hack for terminals slower
3464 than 2400 bps, which throttled Emacs by having it sleep.
3465 This code hasn't worked since at least 2007, when the multi-tty stuff
3466 was added, and anyway those old terminals are long dead.
3467 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3468 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3470 Fix data-loss with --version (Bug#9574).
3471 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3472 as we can't assume that emacs_strerror is initialized, and strerror
3473 is good enough here.
3474 (main): Invoke atexit earlier, to catch earlier instances of
3475 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3477 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3479 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3480 (keyDown): Remap keypad keys to X11 virtual key codes.
3482 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3484 Fix data-loss with --batch (Bug#9574).
3485 * emacs.c: Include <close-stream.h>.
3486 (close_output_streams): New function.
3487 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3488 and handles errors appropriately.
3489 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3492 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3493 The symptom is a diagnostic "GLib-WARNING **: In call to
3494 g_spawn_sync(), exit status of a child process was requested but
3495 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3496 waitpid(), so exit status can't be returned." The diagnostic
3497 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3498 The real bug is a race condition between Emacs and glib: Emacs
3499 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3500 so that glib can't find it. Work around the bug by invoking
3501 waitpid only on subprocesses that Emacs itself creates.
3502 * process.c (create_process, record_child_status_change):
3503 Don't use special value -1 in pid field, as the caller now must
3504 know the pid rather than having the callee infer it.
3505 The inference was sometimes incorrect anyway, due to another race.
3506 (create_process): Set new 'alive' member if child is created.
3507 (process_status_retrieved): New function.
3508 (record_child_status_change): Use it.
3509 Accept negative 1st argument, which means to wait for the
3510 processes that Emacs already knows about. Move special-case code
3511 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3512 processes that have already been waited for, by testing and
3513 clearing new 'alive' member.
3514 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3515 now does this internally.
3516 (handle_child_signal): Let record_child_status_change do all
3517 the work, since we do not want to reap all exited child processes,
3518 only the child processes that Emacs itself created.
3519 * process.h (Lisp_Process): New boolean member 'alive'.
3521 Omit duplicate definitions no longer needed with gcc -g3.
3522 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3523 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3524 Define only as macros. There's no longer any need to also define
3525 these symbols as enums or as constants, since we now assume
3526 gcc -g3 when debugging.
3528 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3530 * lisp.mk: Adjust comments to the fact that term/internal is now
3531 loaded from loadup.el.
3533 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3534 (msdos_fatal_signal): New function.
3535 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3538 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3539 for GCC versions before 4.
3540 (emacs_raise): Define to call msdos_fatal_signal.
3542 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3543 iterator when starting in the middle of a display or overlay
3546 2012-11-03 Chong Yidong <cyd@gnu.org>
3548 * process.c (wait_reading_process_output): Clean up the last
3551 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3553 * process.c (wait_reading_process_output): Avoid a race condition
3554 with SIGIO delivery (Bug#11536).
3556 2012-11-03 Chong Yidong <cyd@gnu.org>
3558 * buffer.c (cursor_type): Untabify docstring.
3560 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3562 * frame.h (struct frame): Drop can_have_scroll_bars member
3563 which is meaningless for a long time. Adjust comments.
3564 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3565 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3567 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3569 * window.c (decode_next_window_args): Update window arg after
3570 calling decode_live_window and so fix crash reported at
3571 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3572 by Juanma Barranquero <lekktu@gmail.com>.
3573 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3574 * font.c (Ffont_at): Likewise.
3576 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3578 * widget.c (resize_cb): New function.
3579 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3580 (EmacsFrameResize): Check if all is up to date before changing frame
3583 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3585 Implement backtrace output for fatal errors on MS-Windows.
3586 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3587 (BACKTRACE_LIMIT_MAX): New macro.
3588 (w32_backtrace): New function.
3589 (emacs_abort): Use w32_backtrace when the user chooses not to
3590 attach a debugger. Update the text of the abort dialog.
3592 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3594 Window-related stuff cleanup here and there.
3595 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3596 Use decode_any_window.
3597 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3598 * xdisp.c (Fformat_mode_line): Likewise.
3599 * font.c (Ffont_at): Use decode_live_window.
3600 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3601 * window.c (decode_next_window_args): Likewise.
3602 (decode_any_window): Remove static.
3603 * window.h (decode_any_window): Add prototype.
3604 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3605 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3608 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3610 Remove pad from struct input_event.
3611 * termhooks.h (struct input_event): Remove padding field.
3613 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3614 member is never cons for a long time. Adjust comment.
3615 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3616 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3617 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3618 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3620 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3622 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3624 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3626 Fix crash when using Emacs as commit editor for git (Bug#12697).
3627 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3628 and it is configured in conf_post.h.
3629 (Fcall_process): Don't invoke both setsid and setpgid; the former
3630 is enough, if it exists.
3631 * callproc.c (Fcall_process, child_setup):
3632 * process.c (create_process): Use setpgid.
3633 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3635 * dispnew.c (init_display): Initialize the foreground group
3636 if we are running a tty display.
3637 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3638 * lisp.h (init_foreground_group): New decl.
3639 * sysdep.c (inherited_pgroup): New static var.
3640 (init_foreground_group, tcsetpgrp_without_stopping)
3641 (narrow_foreground_group, widen_foreground_group): New functions.
3642 (init_sys_modes): Narrow foreground group.
3643 (reset_sys_modes): Widen foreground group.
3645 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3647 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3649 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3651 * minibuf.c (read_minibuf): Restore current buffer since
3652 choose_minibuf_frame calling Fset_frame_selected_window may
3653 change it (Bug#12766).
3655 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3657 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3659 2012-10-30 Kenichi Handa <handa@gnu.org>
3661 * font.c (Ffont_at): If WINDOW is specified and it is not
3662 displaying the current buffer, signal an error.
3664 2012-10-29 Daniel Colascione <dancol@dancol.org>
3666 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3667 In preparation for fixing bug#12739, move these functions from
3670 * coding.h, coding.c: ... to here, and compile them only when
3671 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3672 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3674 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3676 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3677 (timer_loop, getitimer, setitimer): Use it instead of
3678 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3680 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3683 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3685 * nsterm.m (NO_APPDEFINED_DATA): New define.
3686 (last_appdefined_event_data): New variable
3687 (last_appdefined_event): Remove.
3688 (ns_select): Initialize t from last_appdefined_event_data instead
3689 of [last_appdefined_event data1].
3690 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,

3697 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3699 Avoid overflow in w32 implementation of interval timers.
3700 When possible, for ITIMER_PROF count only times the main thread
3702 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3703 'volatile ULONGLONG' types. All the other data which was
3704 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3705 (GetThreadTimes_Proc): New typedef.
3706 (w32_get_timer_time): New function, returns a suitable time value
3708 (timer_loop): Enter critical section when accessing ULONGLONG
3709 values of the itimer_data struct, as these accesses are no longer
3710 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3711 Remove unused variable.
3712 (init_timers): Initialize s_pfn_Get_Thread_Times.
3713 (start_timer_thread): Don't assign itimer->caller_thread here.
3714 (getitimer): Assign itimer->caller_thread here.

3720 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3721 mouse movement events if the menu bar is active. This avoids
3722 producing a busy "hour-glass" cursor by Windows if the mouse
3723 pointer is positioned over a tooltip shown for some menu item.
3725 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3727 Don't assume process IDs fit in int.
3728 * emacs.c (shut_down_emacs) [!DOS_NT]:
3729 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3730 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3731 Use pid_t, not int, to store process IDs, as 'int'
3732 is not wide enough on a few platforms (e.g., AIX and IRIX).
3734 2012-10-23 Kenichi Handa <handa@gnu.org>
3736 The following change is to make face-font-rescale-alist work

3759 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3761 Port to OpenBSD 5.1.
3762 * frame.c (Fmouse_position, Fmouse_pixel_position):
3763 * xdisp.c (produce_stretch_glyph):
3764 Declare local vars only when they're needed.
3765 This is clearer and avoids a warning on OpenBSD about unused vars.

3769 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3770 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3771 as our definition clashes with OpenBSD's.
3772 * xfaces.c (load_face_colors, check_lface_attrs)
3773 (get_lface_attributes_no_remap, get_lface_attributes)
3774 (lface_fully_specified_p, x_supports_face_attributes_p)
3775 (tty_supports_face_attributes_p, face_fontset, realize_face)
3776 (realize_x_face, realize_tty_face):
3777 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3778 merely Lisp_Object *. This is more informative and avoids
3779 a warning on OpenBSD about accessing beyond an object's size.
3781 2012-10-20 Chong Yidong <cyd@gnu.org>
3783 * lread.c (Fload): Doc fix (Bug#12592).

3809 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3810 (staticpro): If we run out of staticpro slots, die with an
3811 informative error instead of just calling emacs_abort.
3813 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3815 Fix two flaws reported by Dmitry Antipov.

4073 the same pointer-to-int (now pointer-to-boolean) &input_pending,

4126 2012-10-08 Daniel Colascione <dancol@dancol.org>
4128 * xdisp.c (start_hourglass): Call w32_note_current_window when

4130 build that caused Emacs to display the hourglass cursor forever.
4132 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4133 which is broken under remote desktop, calculate the number of

4172 2012-10-08 Daniel Colascione <dancol@dancol.org>
4174 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4175 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4176 accidental message numbering hole. Change other messages to
4179 * w32select.h (HAVE_W32SELECT): Remove.
4181 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4182 w32common.h instead of w32heap.h.
4184 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4185 (get_allocation_unit, get_processor_type, get_w32_major_version)
4186 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4187 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4188 (OS_NT, os_subtype, cache_system_info): Move declarations to
4191 * w32heap.c: Include w32common.h.
4192 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4193 (w32_minor_version, w32_build_number, w32_subtype):
4194 Remove duplicate definitions.
4196 * w32fns.c: Include w32common.h; include w32heap.h only in
4199 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4200 Use `report_file_error' instead of `error' in order to better
4201 inform users of what went wrong. Increase NTGUI_UNICODE file
4202 dialog box file name length to 32k, the maximum allowed by the NT
4205 * w32common.h: New file.
4206 (ROUND_UP, ROUND_DOWN, get_page_size)
4207 (get_allocation_unit, get_processor_type, get_w32_major_version)
4208 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4209 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4210 (OS_NT, os_subtype, cache_system_info): Move here.
4212 * unexw32.c, unexcw.c: Include w32common.h.
4214 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4215 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4216 to call syms_of_w32select.
4218 * cygw32.h: Remove obsolete EXFUN declarations.
4220 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4222 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4223 of w32inevt.o from SOME_MACHINE_OBJECTS.
4225 2012-10-08 Daniel Colascione <dancol@dancol.org>
4227 * image.c: Permanent fix for JPEG compilation issue --- limit
4228 jpeglib `boolean' redefinition to Cygwin builds.
4230 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4232 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4234 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4237 2012-10-08 Daniel Colascione <dancol@dancol.org>
4239 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4240 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4241 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4242 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4243 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4244 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4245 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4246 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4247 now a supported configuration.
4249 * Makefile.in: consolidate image variables into LIBIMAGE; add
4250 W32_OBJ and W32_LIBS. Compile new files.
4253 (_DebPrint) declare tracing facility for W32 debugging. We need
4254 to unify tracing later.
4256 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4257 unconditional use of W32 Unicode functions. Cygwin runs only on
4258 100% Unicode operating systems.
4260 * cygw32.c: New file. Define Cygwin-specific facilities.
4261 (Fcygwin_convert_path_to_windows)
4262 (Fcygwin_convert_path_from_windows): New user functions for
4263 accessing Cygwin path-munging routines.
4265 * cygw32.h: New file.
4266 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4267 UTF-16LE strings temporarily inside non-Lisp-visible string
4270 (w32_strerror): Just what it says on the tin.
4272 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4273 also run for Cygwin; both systems have the same problem with using
4274 GUI facilities in a forked child. Also call syms_of_cygw32,
4275 syms_of_w32select in correct places.
4277 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4278 needs fork-then-exec for daemon launching.
4280 * font.h: Include frame.h.
4282 * image.c: Use the image library cache machinery only when we're
4283 compiling for native WINDOWSNT; Cygwin can use shared libraries
4284 like any other Unixlike system.
4286 * keyboard.c: Clarify a comment regarding the input loop.
4288 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4289 functions directly instead of trying to detect at runtime that our
4290 host operating system supports them. We make this change for two
4291 reasons: Cygwin lacks support for the multibyte character
4292 conversion functions used by the legacy menu code, and Cygwin
4293 never needs to rely on non-Unicode APIs.
4295 * unexw32.c (hinst): Declare extern.
4297 * w32.c: Change header order;
4298 (w32_strerror): Move to w32fns.c because we need it for
4299 non-WINDOWSNT builds.
4301 * w32.h: Add #error macro to make sure we don't include w32.h for
4302 Cygwin builds. Remove w32select declarations.
4304 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4305 w32fns.c. w32console.c is WINDOWSNT-only.
4307 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4308 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4310 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4311 (w32_major_version, w32_minor_version, w32_build_number)
4312 (os_subtype, sound_type): Define here
4313 (w32_defined_color): Make color parameter const for consistency
4314 with other _defined_color functions.
4315 (w32_createwindow): Unconditionally call w32_init_class instead of
4316 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4317 through the code is complex and unnecessary because class
4318 registration is practically free.
4319 (w32_name_of_message): New EMACSDEBUG-only function.
4320 (Fset_message_beep): Move here
4321 (Fx_open_connection): Require that the display name for Windows be
4322 "w32" for consistency, emacsclient disambiguation, and maybe, one
4323 day, multi-window-system support.
4324 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4325 Cygwin files for W32 GUI facilities, since these clearly don't
4326 expect Cygwin names.
4327 (_DebPrint): Define.
4328 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4329 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4330 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4331 (w32_last_error): Remove.
4333 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4335 * w32heap.c (syspage_mask): Declare here.
4336 (cache_system_info): Remove.
4338 * w32inevt.c (faked_key): Define globally, not statically.
4339 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4340 (w32_console_toggle_lock_key): Move to w32fns.c.
4342 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4344 * w32proc.c (_DebPrint): Move to w32fns.c.
4345 * w32select.c: Include string.h, stdio.h for Cygwin.
4346 * w32select.h: New File.
4348 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4350 (w32_message_fd): New variable. Under Cygwin, holds the file
4351 descriptor the system used to tell us about pending thread
4354 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4355 that prevented compilation under non-WINDOWSNT systems.
4357 (w32_initialize): Open /dev/windows and assign it to
4358 w32_message_fd. Provide w32 feature.
4360 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4361 (WM_EMACS_INPUT_READY): add.
4362 (prepend_msg, w32_message_fd): Declare globally.
4365 (keyboard_handle): Use only when WINDOWSNT.
4366 (notify_msg_ready): New function. Posts a message to the main
4367 thread's message queue under CYGWIN, which wakes up the main
4368 thread from select(2) by making the /dev/windows file descriptor
4369 ready. Under WINDOWSNT, it sets an event the same way the old
4372 (post, prepend_msg): Actually call notify_msg_ready instead of
4373 setting the input event directly.
4375 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4377 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4378 but it still has blocs in it, don't return it to the system,
4379 instead of aborting. (Bug#12402)
4381 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4383 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4385 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4386 MAC_OS_X_VERSION_10_6.
4387 (syms_of_nsterm): Remove comment about Panther and above for
4389 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4390 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4391 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4393 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4394 MAC_OS_X_VERSION_10_4.
4396 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4397 MAC_OS_X_VERSION_10_2.
4399 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4401 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4402 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4404 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4405 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4406 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4407 Remove ns_in_resize check.
4408 (ns_clear_frame_area): Remove resize handle code.
4410 * nsfns.m (ns_in_resize): Remove.
4411 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4412 Remove ns_in_resize check.
4414 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4416 Improve sys_siglist detection.
4417 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4418 defined as a macro, as is done in Solaris.
4419 (sys_siglist_entries): New macro.
4420 (save_strsignal): Use it.
4421 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4422 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4424 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4426 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4427 fullscreen/Fullscreen.
4429 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4430 tobar_height is new.
4432 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4433 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4434 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4435 (windowDidResize:): Check for correct window if old style fullscreen.
4436 Capitalize word in comment. Remove incorrect comment.
4437 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4438 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4439 error in drawing background.
4440 (toggleFullScreen:): Remove comment. Rearrange calls.
4441 Set toolbar values to zero, save old height in tobar_height.
4442 Restore tool bar height when leaving fullscreen.
4443 (canBecomeMainWindow): New function.
4445 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4447 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4449 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4451 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4453 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4454 that time stamps of directories could also be changed.
4455 Don't request the too broad GENERIC_WRITE, only the more restrictive
4456 FILE_WRITE_ATTRIBUTES access rights.
4458 * fileio.c (Fset_file_times): Special-case ignoring errors for
4459 directories only on MSDOS, not on MS-Windows.
4461 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4463 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4465 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4467 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4468 see whether CreateFile failed.
4470 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4472 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4473 to avoid similar races.
4474 * keyboard.c (pending_signals): Now bool, not int.
4476 Port timers to OpenBSD, plus check for timer failures.
4477 OpenBSD problem reported by Han Boetes.
4478 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4480 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4481 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4482 like OpenBSD, which has timer_settime but does not declare it.
4483 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4484 whether to use itimerspec-related primitives. All uses of
4485 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4487 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4489 * profiler.c (handle_profiler_signal): Fix a malloc race
4490 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4492 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4494 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4496 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4498 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4499 consistent with the change in return value of 'safe_strsignal'.
4501 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4503 Prefer plain 'static' to 'static inline' (Bug#12541).
4504 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4505 (bidi_set_sor_type, bidi_push_embedding_level)
4506 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4507 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4508 (bidi_cache_search, bidi_cache_ensure_space)
4509 (bidi_cache_iterator_state, bidi_cache_find)
4510 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4511 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4512 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4513 Now 'static', not 'static inline'.
4515 Count overruns when profiling; change units to ns.
4516 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4517 Give extra weight to samples after overruns, to attempt to count
4518 the time more accurately.
4519 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4520 the underlying primitives nominally do ns.
4521 (Fprofiler_cpu_start): Document the change. Mention that
4522 the sampling intervals are only approximate.
4524 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4526 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4528 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4529 case for the special 0 coding-system.
4531 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4532 (Fmake_overlay): Remove redundant tests.
4533 (fix_start_end_in_overlays): Remove redundant recentering.
4535 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4537 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4538 Update dependencies.
4540 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4542 Fix a malloc race condition involving strsignal.
4543 A signal can arrive in the middle of a malloc, and Emacs's signal
4544 handler can invoke strsignal, which can invoke malloc, which is
4545 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4546 Fix it by altering the signal handler so that it does not invoke
4548 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4549 * process.c (status_message): Use const pointer, in case strsignal
4550 is #defined to safe_strsignal.
4551 * sysdep.c (sys_siglist, init_signals): Always define and
4552 initialize a substitute sys_siglist if the system does not define
4553 one, even if HAVE_STRSIGNAL.
4554 (safe_strsignal): Rename from strsignal. Always define,
4555 using sys_siglist. Return a const pointer.
4556 * syssignal.h (safe_strsignal): New decl.
4557 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4559 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4561 * w32proc.c (timer_loop): Fix code that waits for timer
4562 expiration, to avoid high CPU usage.
4564 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4566 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4567 (sweep_weak_table): Remove redundant prototypes.
4569 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4571 * emacs.c: Move the inclusion of TERM_HEADER after including
4572 windows.h on WINDOWSNT. This avoids compilation problems with
4575 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4577 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4578 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4579 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4580 as the previous version used 'void *'.
4582 * ralloc.c (ROUNDUP): Fix last change.
4583 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4586 * w32proc.c <disable_itimers>: New static flag.
4587 (init_timers): Initialize it to zero, after creating the critical
4588 sections used by the timer threads.
4589 (term_timers): Set to 1 before deleting the critical sections.
4590 (getitimer, setitimer): If disable_itimers is non-zero, return an
4591 error indication without doing anything. Reported by Fabrice
4592 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4593 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4595 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4598 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4599 term_ntproc after all the other bookkeeping, to get timers working
4600 as long as possible.
4602 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4604 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4605 Suggested by Juri Linkov in
4606 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4608 Prefer plain 'static' to 'static inline' (Bug#12541).
4609 With static functions, modern compilers inline pretty well by
4610 themselves; advice from programmers often hurts as much as it helps.
4611 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4612 this change shrinks the text size of the Emacs executable by 1.1%
4613 without affecting CPU significantly in my benchmark.
4614 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4615 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
4616 (mark_maybe_object, mark_maybe_pointer, bounded_number):

4618 (bset_auto_fill_function, bset_auto_save_file_format)
4619 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

4912 for consistency with other handlers.
4913 (setup_cpu_timer): New function, with much of what used to be in

4915 Prefer timer_settime if available, and prefer
4916 thread cputime clocks, then process cputime clocks, then

4918 to round more-correctly when falling back to setitimer.
4919 (Fprofiler_cpu_start): Use it.

4986 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4987 Since this stuff is now private to charset.c, there's no need for
4988 a public macro and no need to inline by hand.

5098 now return bool, not int. All uses changed.
5099 * image.c: Omit unnecessary static decls.
5100 (x_create_bitmap_mask, x_build_heuristic_mask):
5101 Return void, not int, since callers don't care about the return value.

5136 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5138 Move pid_t related decls out of lisp.h.
5139 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5140 (interruptible_wait_for_termination):
5141 Move these decls from lisp.h to syswait.h, since they use pid_t.
5142 Needed on FreeBSD; see Herbert J. Skuhra in
5143 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5144 * callproc.c: Include syswait.h.

5164 Use bool for boolean.
5165 * gtkutil.c (xg_update_frame_menubar):

5190 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5192 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5193 fatal_error_backtrace.
5195 * w32proc.c (sys_kill): Undo last change: don't do anything when
5196 invoked to deliver SIGABRT to our own process. This is now
5197 handled by emacs_raise.
5199 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5201 * w32term.c (w32_read_socket): Remove leftover reference to
5202 interrupt_input_pending.
5204 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5206 Do not use SA_NODEFER.
5207 Problem reported by Dani Moncayo in
5208 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5210 * sysdep.c (emacs_abort): Do not reset signal handler.
5211 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5212 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5213 wanted even on POSIXish hosts, and it doesn't work on Windows.
5215 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5217 * xterm.c (x_term_init): Call fixup_locale before and after calling
5218 gtk_init (Bug#12392).
5220 2012-09-23 Chong Yidong <cyd@gnu.org>
5222 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5223 Vdynamic_library_alist.
5225 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5226 (Fgnutls_available_p): Caller changed.
5228 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5229 (Flibxml_parse_xml_region): Likewise.
5231 * dispextern.h (struct image_type): Remove arg from init function.
5233 * image.c (Finit_image_library, lookup_image_type)
5234 (define_image_type): Remove now-unneeded second arg.
5235 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5236 (init_tiff_functions, init_gif_functions, init_svg_functions):
5237 Arglist and w32_delayed_load calling convention changed.
5238 (gs_type): Remove init_gs_functions; there is no such function.
5239 (valid_image_p, make_image): Fix caller to lookup_image_type.
5241 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5243 Simplify and avoid signal-handling races (Bug#12471).
5245 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5246 Avoid recursive loop if there's a fatal error in the function itself.
5247 * atimer.c (pending_atimers):
5248 * blockinput.h: Don't include "atimer.h"; no longer needed.
5249 (interrupt_input_pending): Remove. All uses removed.
5250 pending_signals now counts both atimers and ordinary interrupts.
5251 This is less racy than having three separate pending-signal flags.
5252 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5254 Rename from their upper-case counterparts BLOCK_INPUT,
5255 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5256 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5257 This makes it easier to access volatile variables more accurately.
5258 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5259 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5260 that's more reliable if the code is buggy and sets
5261 interrupt_input_blocked to a negative value. All uses changed.
5262 * atimer.c (deliver_alarm_signal):
5263 Remove. No need to deliver this to the parent; any thread can
5264 handle this signal now. All uses replaced by underlying handler.
5265 * atimer.c (turn_on_atimers):
5266 * dispnew.c (handle_window_change_signal):
5267 * emacs.c (handle_danger_signal):
5268 * keyboard.c (kbd_buffer_get_event):
5269 Don't reestablish signal handler; not needed with sigaction.
5270 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5272 Rework to avoid unnecessary accesses to volatile variables.
5273 (UNBLOCK_INPUT_TO): Now a function.
5274 (totally_unblock_input, unblock_input): New decls.
5275 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5276 (init_data): Remove. Necessary stuff now done in init_signal.
5277 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5278 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5279 (fatal_error_code): Remove; no longer needed.
5280 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5281 it doesn't always backtrace. All uses changed. No need to reset
5282 signal to default, since sigaction and/or die does that for us now.
5283 Use emacs_raise (FOO), not kill (getpid (), FOO).
5284 (main): Check more-accurately whether we're dumping.
5285 Move fatal-error setup to sysdep.c
5286 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5287 * gtkutil.c (xg_get_file_name, xg_get_font):
5288 Remove no-longer-needed signal-mask manipulation.
5289 * keyboard.c, process.c (POLL_FOR_INPUT):
5290 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5291 * keyboard.c (read_avail_input): Remove.
5292 All uses replaced by gobble_input.
5293 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5294 (kbd_buffer_store_event_hold, gobble_input):
5295 (record_asynch_buffer_change) [USABLE_SIGIO]:
5296 (store_user_signal_events):
5297 No need to mess with signal mask.
5298 (gobble_input): If blocking input and there are terminals, simply
5299 set pending_signals to 1 and return. All hooks changed to not
5300 worry about whether input is blocked.
5301 (process_pending_signals): Clear pending_signals before processing
5302 them, in case a signal comes in while we're processing.
5303 By convention callers now test pending_signals before calling us.
5304 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5305 New functions, to support changes to blockinput.h.
5306 (handle_input_available_signal): Now extern.
5307 (reinvoke_input_signal): Remove. All uses replaced by
5309 (quit_count): Now volatile, since a signal handler uses it.
5310 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5311 All callers changed. Block SIGINT only if not already blocked.
5312 Clear sigmask reliably, even if Fsignal returns, which it can.
5313 Omit unnecessary accesses to volatile var.
5314 (quit_throw_to_read_char): No need to restore sigmask.
5315 * keyboard.c (gobble_input, handle_user_signal):
5316 * process.c (wait_reading_process_output):
5317 Call signal-handling code rather than killing ourselves.
5318 * lisp.h: Include <float.h>, for...
5319 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5320 (pending_signals): Now volatile.
5321 (syms_of_data): Now const if IEEE floating point.
5322 (handle_input_available_signal) [USABLE_SIGIO]:
5323 (terminate_due_to_signal, record_child_status_change): New decls.
5324 * process.c (create_process): Avoid disaster if memory is exhausted
5325 while we're processing a vfork, by tightening the critical section
5327 (send_process_frame, process_sent_to, handle_pipe_signal)
5328 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5330 (send_process): No need for setjmp/longjmp any more, since the
5331 SIGPIPE stuff is now gone. Instead, report an error if errno
5333 (record_child_status_change): Now extern. PID and W are now args.
5334 Return void, not bool. All callers changed.
5335 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5336 Remove. All uses removed. This bug should be fixed now in a
5338 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5339 and record the child status change directly. This avoids the
5340 need to futz with the signal mask.
5341 (process_fatal_action): Move here from emacs.c.
5342 (emacs_sigaction_flags): New function, containing
5343 much of what used to be in emacs_sigaction_init.
5344 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5345 caught by emacs, to make races less likely.
5346 (deliver_process_signal): Rename from handle_on_main_thread.
5348 (BACKTRACE_LIMIT_MAX): Now at top level.
5349 (thread_backtrace_buffer, threadback_backtrace_pointers):
5351 (deliver_thread_signal, deliver_fatal_thread_signal):
5352 New functions, for more-accurate delivery of thread-specific signals.
5353 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5354 (deliver_arith_signal): Handle in this thread, not
5355 in the main thread, since it's triggered by this thread.
5356 (maybe_fatal_sig): New function.
5357 (init_signals): New arg DUMPING so that we can be more accurate
5358 about whether we're dumping. Caller changed.
5359 Treat thread-specific signals differently from process-general signals.
5360 Block all signals while handling fatal error; that's safer.
5361 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5363 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5364 Ignore SIGPIPE unless batch.
5365 (emacs_backtrace): Output backtrace for the appropriate thread,
5366 which is not necessarily the main thread.
5367 * syssignal.h: Include <stdbool.h>.
5368 (emacs_raise): New macro.
5369 * xterm.c (x_connection_signal): Remove; no longer needed
5370 now that we use sigaction.
5371 (x_connection_closed): No need to mess with sigmask now.
5372 (x_initialize): No need to reset SIGPIPE handler here, since
5373 init_signals does this for us now.
5375 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5377 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5378 background rect may be larger (Bug#12245).
5380 2012-09-23 Chong Yidong <cyd@gnu.org>
5382 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5384 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5386 * .gdbinit: Just stop at fatal_error_backtrace.
5387 See Stefan Monnier's request in
5388 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5389 Remove no-longer-used query of system type.
5391 2012-09-22 Chong Yidong <cyd@gnu.org>
5393 * search.c (Freplace_match): Doc fix (Bug#12325).
5395 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5397 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5398 (Fline_end_position): Doc fix.
5400 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5402 2012-09-22 Chong Yidong <cyd@gnu.org>
5404 * dispextern.h (struct image_type): Add new slot, storing a type
5405 initialization function.
5407 * image.c (define_image_type): Call the image initializer function
5408 if it is defined. Arguments and return value changed.
5409 (valid_image_p, make_image): Callers changed.
5410 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5411 (gif_type, imagemagick_type, svg_type, gs_type):
5412 Add initialization functions.
5413 (Finit_image_library): Call lookup_image_type.
5414 (CHECK_LIB_AVAILABLE): Macro deleted.
5415 (lookup_image_type): Call define_image_type here, rather than via
5416 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5417 (syms_of_image): Move define_image_type calls for xbm_type and
5418 pbm_type to lookup_image_type.
5420 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5422 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5423 'idle_timers' from here ...
5424 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5425 lists, to avoid infloops when the timer does something stupid,
5426 like reinvoke itself with the same or smaller time-out.
5429 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5431 * window.c (Fsplit_window_internal): Handle only Qt value of
5432 Vwindow_combination_limit separately.
5433 (Qtemp_buffer_resize): New symbol.
5434 (Vwindow_combination_limit): New default value.
5437 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5439 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5440 the new overlay string. (Bug#10159)
5442 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5444 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5445 or that fprintf is async-signal-safe. POSIX doesn't require
5448 2012-09-22 Chong Yidong <cyd@gnu.org>
5450 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5453 2012-09-22 Kenichi Handa <handa@gnu.org>
5455 * composite.c (composition_reseat_it): Handle the case that a
5456 grapheme cluster is not covered by a single font (Bug#12352).
5458 2012-09-21 Chong Yidong <cyd@gnu.org>
5460 * image.c (define_image_type): Avoid adding duplicate types to
5461 image_types (Bug#12463). Suggested by Jörg Walter.
5463 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5465 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5466 (print_load_command_name): Add case LC_DATA_IN_CODE.
5467 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5469 2012-09-21 Glenn Morris <rgm@gnu.org>
5471 * eval.c (Frun_hook_with_args_until_success)
5472 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5474 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5476 * fileio.c (Ffile_selinux_context): Only call freecon when
5477 lgetfilecon succeeded.
5478 (Fset_file_selinux_context): Likewise. (Bug#12444)
5480 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5482 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5483 reordering, locate the cursor by calling set_cursor_from_row; if
5484 that fails, clear the desired glyph matrix before returning a
5485 failure indication to the caller. Fixes leaving garbled display
5486 when fast scrolling with a down-key. (Bug#12403)
5487 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5488 scrolling through multibyte text.
5490 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5492 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5493 calling mark_vectorlike since that's the one that marks the window.
5494 (mark_discard_killed_buffers): Mark the final cdr.
5495 * window.h (struct window): Move prev/next_buffers to the
5496 non-standard fields.
5497 * window.c (make_window): Initialize prev/next_buffers manually.
5499 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5501 Omit unused arg EXPECTED from socket hooks.
5502 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5503 * nsterm.m (ns_term_init):
5504 * termhooks.h (struct terminal.read_socket_hook):

5506 * w32term.c (w32_read_socket):
5507 * xterm.c (XTread_socket):
5508 Omit unused arg EXPECTED. All callers changed.
5509 (store_user_signal_events): Return void, not int, since callers no
5510 longer care about the return value. All uses changed.
5512 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5514 * w32gui.h (XParseGeometry): Do not declare.
5516 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5518 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5519 Ignore 'expected'. See Eli Zaretskii in
5520 <http://bugs.gnu.org/12471#8> (last line).
5522 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5523 (XParseGeometry): Now static. Substitute extremal values for
5524 values that are out of range.
5526 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5528 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5530 * nsfns.m (XParseGeometry): Remove.
5531 (Fx_create_frame): Call x_set_offset to correctly interpret
5532 top_pos in geometry.
5534 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5535 (Fx_parse_geometry): If there is a space in string, call
5536 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5538 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5540 * search.c (scan_buffer): Use character positions in calls to
5541 region_cache_forward and region_cache_backward, not byte
5542 positions. (Bug#12196)
5544 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5545 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5547 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5548 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5549 emacs_blocked_malloc, now deleted.
5551 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5553 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5554 The workaround was for improving performance on Solaris 2.4, but
5555 is getting in the way now. Emacs will still work if someone is
5556 still running Solaris 2.4 in a museum somewhere; Sun dropped
5557 support for Solaris 2.4 in 2003.
5558 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5559 * process.c (create_process) [HAVE_WORKING_VFORK]:
5560 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5561 since Emacs no longer uses vfork on that platform.
5563 2012-09-17 Glenn Morris <rgm@gnu.org>
5565 * emacs.c: Use COPYRIGHT.
5567 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5569 Remove configure's --without-sync-input option (Bug#12450).
5570 When auditing signal-handling in preparation for cleaning it up,
5571 I found that SYNC_INPUT has race conditions and would be a real
5572 pain to fix. Since it's an undocumented and deprecated
5573 configure-time option, now seems like a good time to remove it.
5574 Also see <http://bugs.gnu.org/11080#16>.
5575 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5576 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5577 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5578 (malloc_hysteresis):
5579 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5580 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5581 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5582 (dont_register_blocks, bytes_used_when_reconsidered)
5583 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5584 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5585 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5586 Remove. All uses removed.
5587 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5588 implementation, one that depends on whether the new macro
5589 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5591 * atimer.c (run_timers, handle_alarm_signal):
5592 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5593 (handle_async_input, process_pending_signals)
5594 (handle_input_available_signal, init_keyboard):
5595 * nsterm.m (ns_read_socket):
5596 * process.c (wait_reading_process_output):
5597 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5598 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5600 * xterm.c (XTread_socket):
5602 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5603 * eval.c (handling_signal): Remove. All uses removed.
5604 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5605 All uses replaced with the SYNC_INPUT version.
5606 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5608 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5611 * font.c (Ffont_shape_gstring): Remove unused local.
5613 2012-09-16 Glenn Morris <rgm@gnu.org>
5615 * Makefile.in (clean): No longer run nextstep's clean.
5617 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5619 (ns-app): Move here from ns.mk, and simplify.
5620 (clean): Simplify nextstep entry.
5621 * ns.mk: Remove file.
5623 2012-09-17 Kenichi Handa <handa@gnu.org>
5625 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5626 not covert the last few charactes.
5628 2012-09-16 Kenichi Handa <handa@gnu.org>
5630 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5631 here, but just check the validity of glyphs in the glyph-string.
5633 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5635 * window.c (Fwindow_parameter, Fset_window_parameter):
5636 Accept any window as argument (Bug#12452).
5638 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5640 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5641 to ns_term_init to avoid memory leak.
5643 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5644 explicit retain/release.
5645 (ns_term_init): Only allow one display. Initialize outerpool and
5648 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5650 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5651 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5652 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5653 the Microsoft problem in a different way, by altering ../nt/config.nt.
5655 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5670 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5671 by lisp.h. This completes removal of setjmp.h inclusion
5672 erroneously announced in the previous commit. (Bug#12446)
5674 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5677 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5678 not defined as a macro. The latter happens on MS-Windows.
5681 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5683 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5684 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5685 Some instances of '#include <setjmp.h>' removed, if the
5686 only reason for the instance was because "lisp.h" was included.
5687 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5688 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5689 and _longjmp with the new symbols. Emacs already uses _setjmp if
5690 available, so this change affects only POSIXish hosts that have
5691 sigsetjmp but not _setjmp, such as some versions of Solaris and
5692 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5693 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5694 (png_load_body) [HAVE_PNG]:
5695 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5696 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5697 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5698 since PNG requires jmp_buf. This is the only exception to the
5699 general rule that we now use sys_setjmp and sys_longjmp.
5700 This exception is OK since this code does not change the signal
5701 mask or longjmp out of a signal handler.
5703 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5705 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5706 Include "syssignal.h", for 'main_thread'.
5708 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5710 Avoid out-of-range marker position (Bug#12426).
5711 * insdel.c (replace_range, replace_range_2):
5712 Adjust markers before overlays, as suggested by comments.
5713 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5714 Remove redundant check before calling offset_intervals.
5716 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5718 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5719 current buffer (Bug#12387).
5721 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5723 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5725 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5727 Use a more backwards-compatible timer format (Bug#12430).
5728 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5729 vector element, not from the 4th, since PSECS is now at the end.
5730 (Fcurrent_idle_time): Doc fix.
5732 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5734 Function to mark objects and remove killed buffers at once.
5735 * alloc.c (discard_killed_buffers): Rename to ...
5736 (mark_discard_killed buffers) ... new name. Add marking
5737 of remaining objects. Fix comment. Adjust users.
5738 (mark_object): Do not touch frame buffer lists here.
5739 * frame.c (delete_frame): Reset frame buffer lists here.
5741 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5743 Better workaround for GNOME bug when --enable-gcc-warnings.
5744 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5745 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5746 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5748 Simplify SIGIO usage (Bug#12408).
5749 The code that dealt with SIGIO was crufty and confusing, e.g., it
5750 played tricks like "#undef SIGIO" but these tricks were not used
5751 consistently. Simplify mostly by not #undeffing standard symbols,
5752 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5753 or not as we please) rather than "defined SIGIO" (standard symbol
5754 that we probably shouldn't #undef).
5755 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5756 Modules that need it can include it.
5757 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5758 * dispextern.h (ignore_sigio): New decl.
5759 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5760 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5761 * emacs.c (shut_down_emacs):
5762 * keyboard.c (kbd_buffer_store_event_hold):
5763 Use ignore_sigio rather than invoking 'signal' directly.
5764 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5766 (FIONREAD, SIGIO): Do not #undef.
5767 (tty_read_avail_input): Use #error rather than a syntax error.
5768 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5769 for I_PIPE, used by SETUP_SLAVE_PTY.
5770 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5771 * sysdep.c (croak): Remove; no longer needed. This bit of
5772 temporary code, with Fred N. Fish's comment that it's temporary,
5773 has been in Emacs since at least 1992!
5774 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5775 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5776 * syssignal.h (croak): Remove decl.
5777 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5778 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5779 now that we're termios-only.
5780 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5781 * term.c (dissociate_if_controlling_tty): Use #error rather than
5784 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5785 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5786 to work around GNOME bug 683906.
5787 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5788 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5789 This works around GCC bug 54561.
5791 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5793 More fixes for 'volatile' and setjmp/longjmp.
5794 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5795 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5796 (png_load_body) [HAVE_PNG]:
5797 (jpeg_load_body) [HAVE_JPEG]:
5798 New function, with most of the old parent function's body.
5799 (png_load) [HAVE_PNG]:
5800 (jpeg_load) [HAVE_JPEG]:
5801 Invoke the new function, to avoid longjmp munging our locals.
5802 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5803 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5804 longjmp is passed 2, as the C standard doesn't guarantee this.
5805 Instead, store the failure code into mgr->failure_code.
5807 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5809 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5810 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5811 (syms_of_keyboard): Remove support for unread-command-char.
5813 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5815 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5816 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5817 violation. (Bug#12426)
5819 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5821 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5823 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5825 * eval.c: Add `inhibit-debugger'.
5826 (Qinhibit_debugger): New symbol.
5827 (call_debugger): Bind it instead of Qdebug_on_error.
5828 (maybe_call_debugger): Test Vinhibit_debugger.
5829 (syms_of_eval): Define inhibit-debugger.
5830 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5831 (syms_of_xdisp): Remove inhibit-debug-on-message.
5833 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5835 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5836 If a nonvolatile local variable is written before a _longjmp to
5837 the frame containing the variable, and is read after the _longjmp,
5838 the value read is indeterminate. Some local variables of type
5839 'struct handler' and 'struct catchtag' are used in this way, so
5840 mark each of their slots as volatile if the slot can be set before
5841 _longjmp and read afterwards.
5842 * lisp.h (struct handler): var and chosen_clause are now volatile.
5843 (struct catchtag): val, next, and pdlcount are now volatile.
5845 * bidi.c (bidi_push_it, bidi_pop_it):
5846 * fns.c (copy_hash_table):
5847 * image.c (define_image_type):
5848 * keyboard.c (kbd_buffer_store_event_hold):
5849 * process.c (Fprocess_send_eof):
5850 * xfaces.c (x_create_gc) [HAVE_NS]:
5851 * xgselect.c (xg_select):
5852 Prefer assignment to memcpy when either will do.
5854 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5855 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5856 time an item is removed. No need to mark this function 'inline';
5857 the compiler knows better than we do.
5859 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5861 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5862 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5863 to change_frame_size (Bug#12388).
5864 (windowDidResize:): Pass YES to updateFrameSize.
5866 * nsterm.h: Add delay parameter to updateFrameSize.
5868 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5870 Discard killed buffers from deleted window and frame objects.
5871 This reduces an amount of references to killed buffers and
5872 helps GC to reclaim them faster.
5873 * alloc.c (discard_killed_buffers): New function.
5874 (mark_object): Use it for deleted windows and frames.
5875 (mark_object): If symbol's value is set up for a killed buffer
5876 or deleted frame, restore its global binding.
5877 * data.c (swap_in_global_binding): Add GC notice.
5878 (swap_in_symval_forwarding): Use convenient set_blv_where.
5879 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5880 * window.h: ... to here.
5882 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5884 Convenient macro to check whether the buffer is live.
5885 * buffer.h (BUFFER_LIVE_P): New macro.
5886 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5887 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5889 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5891 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5892 composition cases (Bug#12364).
5894 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5895 overhang of succeeding glyphs overlapping box cursor.
5897 * w32term.c (x_draw_glyph_string): Likewise.
5899 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5901 Simplify, document, and port floating-point (Bug#12381).
5902 The porting part of this patch fixes bugs on non-IEEE platforms
5903 with frexp, ldexp, logb.
5904 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5906 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5907 support, by removing commented-out code and briefly listing the
5908 C89 functions excluded. The commented-out stuff was confusing
5909 maintenance, e.g., we thought we needed cbrt but it was commented out.
5910 (logb): Remove decl; no longer needed.
5911 (isfinite): New macro, if not already supplied.
5912 (isnan): Don't replace any existing macro.
5913 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5914 are present on all C89 platforms.
5915 (Ffrexp): Do not special-case zero, as frexp does the right thing
5917 (Flogb): Do not use logb, as it doesn't have the desired meaning
5918 on hosts that use non-base-2 floating point. Instead, stick with
5919 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5920 frexp, to avoid getting an unspecified result.
5922 * xdisp.c (Qinhibit_debug_on_message): Now static.
5924 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5926 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5927 NSBezierPath (Bug#12131).
5929 2012-09-10 Chong Yidong <cyd@gnu.org>
5931 * fns.c (Fdelq, Fdelete): Doc fix.
5933 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5935 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5936 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5938 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5940 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5941 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5944 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5946 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5947 left fringe if the window has a left margin. This avoids leaving
5948 traces of the cursor because its leftmost pixel is not drawn over.
5950 * dispnew.c (update_window_line): When the left margin area of a
5951 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5952 that screen line. (Bug#12277)
5954 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5956 Assume C89 or later for math functions (Bug#12381).
5957 This simplifies the code, and makes it a bit smaller and faster,
5958 and (most important) makes it easier to clean up signal handling
5959 since we can stop worring about floating-point exceptions in
5960 library code. That was a problem before C89, but the problem
5961 went away many years ago on all practical Emacs targets.
5962 * data.c, image.c, lread.c, print.c:
5963 Don't include <math.h>; no longer needed.
5964 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5965 might be autoconfigured, as that never happens.
5967 * doprnt.c (DBL_MAX_10_EXP):
5968 * print.c (DBL_DIG):
5969 Remove. C89 or later always defines these.
5970 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5971 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5972 (arith_error, domain_error, domain_error2):
5973 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5974 no longer needed -- we simply return what C returns. All uses removed.
5975 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5977 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5978 Remove. All uses expanded, as these macros are no longer used
5979 more than once and are now more trouble than they're worth.
5980 (Ftan): Use tan, not sin / cos.
5981 (Flogb): Assume C89 frexp.
5982 (fmod_float): Assume C89 fmod.
5983 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5984 (init_floatfns): Remove. All uses removed.
5986 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5988 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5989 compositeToPoint for OSX < 10.6 (Bug#12390).
5991 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5993 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5994 This produces more-accurate results.
5996 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5998 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5999 changes (Bug#12088).
6001 2012-09-08 Chong Yidong <cyd@gnu.org>
6003 * syntax.c (Fstring_to_syntax): Doc fix.
6005 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6007 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6008 in the internal border.
6009 (x_set_window_size): Remove static variables and their usage.
6010 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6011 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6012 Remove fringe/internal border adjustment (Bug#11052).
6013 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6014 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6015 (ns_fix_rect_ibw): Remove.
6016 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6017 (ns_dumpglyphs_box_or_relief): Ditto.
6018 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6020 (ns_dumpglyphs_image): Ditto.
6021 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6023 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6024 their usage. Add fringe_extended_p and its use as in other terms.
6025 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6026 scroll bar was removed.
6027 (updateFrameSize): New function.
6028 (windowDidResize): Move code to updateFrameSize and call it.
6030 * nsterm.h (EmacsView): Add updateFrameSize.
6032 2012-09-07 Chong Yidong <cyd@gnu.org>
6034 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6036 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6038 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6040 More signal-handler cleanup (Bug#12327).
6041 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6042 Problem introduced when merging patches. Noted by Eli Zaretskii in
6043 <http://bugs.gnu.org/12327#67>.
6044 * floatfns.c: Comment fix.
6045 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6046 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6047 and anyway the declaration is harmless even if SIGDANGER is not defined.
6048 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6049 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6050 source files not surprisingly expected syssignal.h to define, or
6051 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6052 Include <sys/ioctl.h>, for FIONREAD.
6053 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6054 This eliminates a problem whereby other files mysteriously had
6055 to include "syssignal.h" before including "systty.h" if they
6056 wanted to use "#ifdef SIGIO".
6058 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6060 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6062 * w32.c (sigemptyset): Empty the set.
6063 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6065 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6067 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6069 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6070 (mark_object): Likewise for frame objects.
6072 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6074 * syssignal.h (handle_on_main_thread): Always declare,
6075 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6076 This ports to platforms without HAVE_PTHREAD.
6078 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6080 Signal-handler cleanup (Bug#12327).
6081 Emacs's signal handlers were written in the old 4.2BSD style with
6082 sigblock and sigmask and so forth, and this led to some
6083 inefficiencies and confusion. Rewrite these to use
6084 pthread_sigmask etc. without copying signal sets around. Also,
6085 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6086 'signal', and instead use functions that do not attempt to take
6087 over the system name space. This patch causes Emacs's text
6088 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6089 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6090 Do not include <signal.h> or "syssignal.h", as these
6091 modules do not use signals.
6092 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6093 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6094 Do not include <signal.h>, as "syssignal.h" does that for us now.
6095 * atimer.c (sigmask_atimers): New function.
6096 (block_atimers, unblock_atimers): New functions,
6097 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6099 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6100 no longer needed here.
6101 * emacs.c (main): Inspect existing signal handler with sigaction,
6102 so that there's no need to block and unblock SIGHUP.
6103 * sysdep.c (struct save_signal): New member 'action', replacing
6104 old member 'handler'.
6105 (save_signal_handlers, restore_signal_handlers):
6106 Use sigaction instead of 'signal' to save and restore.
6107 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6108 New function. All users of 'signal' modified to use set_sighandler
6109 if they're writeonly, and to use sys_signal if they're read+write.
6110 (emacs_sigaction_init, forwarded_signal): New functions.
6111 (sys_signal): Remove. All uses replaced by calls to sigaction
6112 and emacs_sigaction_init, or by direct calls to 'signal'.
6113 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6114 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6115 all uses replaced by pthread_sigmask etc. calls.
6116 * syssignal.h: Include <signal.h>.
6117 (emacs_sigaction_init, forwarded_signal): New decls.
6118 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6119 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6120 (sigmask, sys_sigmask): Remove; no longer needed.
6121 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6122 (sigblock, sigunblock, sigfree):
6123 (sigsetmask) [!defined sigsetmask]:
6124 Remove. All uses replaced by pthread_sigmask.
6125 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6126 no longer need to be replaced, and its typical old uses
6127 are now done via emacs_sigaction_init and sigaction.
6128 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6129 (sys_sigdel): Remove; unused.
6130 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6132 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6134 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6135 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6137 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6139 Explicitly mark buffer_defaults and buffer_local_symbols.
6140 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6141 mark_local_symbols here.
6142 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6143 since special buffers aren't marked here any more.
6144 (allocate_buffer): Chain new buffer with all_buffers here...
6145 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6147 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6148 (syms_of_buffer): Remove staticpro of the above.
6149 (init_buffer_once): Set names for buffer_defaults and
6150 buffer_local_symbols.
6152 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6154 Use bool for booleans in font-related modules.
6155 * font.c (font_intern_prop, font_style_to_value)
6156 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6157 (generate_otf_features, font_check_otf_features, font_check_otf)
6158 (font_match_p, font_list_entities, font_at):
6159 * fontset.c (fontset_id_valid_p, reorder_font_vector
6160 (fontset_find_font, Fset_fontset_font)
6161 (face_suitable_for_char_p) [0]:
6162 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6163 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6164 (m17n_flt_initialized, ftfont_shape_by_flt):
6165 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6166 * nsfont.m (nsfont_draw):
6167 * w32font.c (w32font_draw):
6168 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6169 Use bool for booleans.
6170 * font.h: Adjust to above API changes.
6171 (struct font, struct font_driver, struct font_driver_list):
6172 Use bool for booleans.
6173 (struct font): Remove useless member encoding_type.
6175 * fontset.c, xftfont.c: Omit unnecessary static decls.
6177 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6179 * alloc.c (mark_object): Revert window marking code
6180 since it's unsafe for the Fset_window_configuration.
6182 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6184 Fix race conditions with signal handlers and errno (Bug#12327).
6185 Be more systematic about preserving errno whenever a signal
6186 handler returns, even if it's not in the main thread. Do this by
6187 renaming signal handlers to distinguish between signal delivery
6188 and signal handling. All uses changed.
6189 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6190 * data.c (deliver_arith_signal): Rename from arith_error.
6191 * dispnew.c (deliver_window_change_signal): Rename from
6192 window_change_signal.
6193 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6194 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6195 * keyboard.c (deliver_input_available_signal): Rename from
6196 input_available_signal.
6197 (deliver_user_signal): Rename from handle_user_signal.
6198 (deliver_interrupt_signal): Rename from interrupt_signal.
6199 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6200 (deliver_child_signal): Rename from sigchld_handler.
6201 * atimer.c (handle_alarm_signal):
6202 * data.c (handle_arith_signal):
6203 * dispnew.c (handle_window_change_signal):
6204 * emacs.c (handle_fatal_signal, handle_danger_signal):
6205 * keyboard.c (handle_input_available_signal):
6206 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6207 * process.c (handle_pipe_signal, handle_child_signal):
6208 New functions, with the actual signal-handling code taken from the
6209 original respective signal handlers, sans the sporadic attempts to
6210 preserve errno, since that's now done by handle_on_main_thread.
6211 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6212 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6213 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6215 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6216 Move initialization of main_thread to sysdep.c's init_signals.
6217 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6218 our usage, and simplifies the mainline code.
6219 (record_child_status_change): New static function, as a helper
6220 for handle_child_signal, and with most of the old child handler's
6222 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6223 (handle_child_signal): Use the above.
6224 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6225 Moved here from emacs.c.
6226 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6227 code moved here from emacs.c's main function.
6228 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6229 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6230 This lets callers save and restore errno properly.
6232 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6234 Remove redundant or unused things here and there.
6235 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6236 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6237 * editfns.c (Fcompare_buffer_substrings): Likewise.
6238 * frame.h (struct terminal, struct font_driver_list):
6239 Remove redundant declarations.
6240 * window.h (Qleft, Qright): Likewise.
6242 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6244 Do not mark objects from deleted buffers, windows and frames.
6245 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6246 (mark_object): Likewise for windows and frames.
6248 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6250 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6251 buffer_defaults and buffer_local_symbols as valid objects.
6252 Return special value to denote them.
6254 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6256 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6257 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6258 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6259 (file_name_absolute_p, Fsubstitute_in_file_name):
6260 (check_executable, check_writable, Ffile_accessible_directory_p)
6261 (Fset_file_selinux_context, Fdefault_file_modes)
6262 (Finsert_file_contents, choose_write_coding_system)
6263 (Fwrite_region, build_annotations, a_write, e_write)
6265 * filelock.c (boot_time_initialized, get_boot_time)
6266 (get_boot_time_1, lock_file_1, within_one_second):
6267 * floatfns.c (in_float):
6268 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6269 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6270 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6271 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6272 * window.c (compare_window_configurations):
6273 Use bool for booleans.
6274 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6275 (Fdefault_file_modes): Now mode_t, not int, for modes.
6276 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6277 (internal_delete_file): Now returns void, not a (boolean) int,
6278 since nobody was looking at the return value.
6279 * lisp.h, window.h: Adjust to above API changes.
6281 * xdisp.c (set_message): Simplify and reindent last change.
6283 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6285 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6287 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6289 * eval.c (call_debugger): Make the function non-static so that we
6290 can call it from set_message.
6292 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6293 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6295 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6297 Give more-useful info on a fatal error (Bug#12328).
6298 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6299 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6300 of doing the work ourselves.
6301 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6302 do most of the work.
6303 (fatal_error_backtrace): New function, taken from the guts
6304 of the old fatal_error_signal, but with a new option to output
6306 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6307 info about the signal than just its number.
6308 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6309 * sysdep.c: Include <execinfo.h>
6310 (emacs_backtrace): New function, taken partly from the previous
6311 code of the 'die' function.
6312 (emacs_abort): Call fatal_error_backtrace rather than abort.
6314 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6316 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6317 eager (load-time) macro-expansion.
6318 * lisp.mk (lisp): Add macroexp.
6320 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6322 Simplify redefinition of 'abort' (Bug#12316).
6323 Do not try to redefine the 'abort' function. Instead, redo
6324 the code so that it calls 'emacs_abort' rather than 'abort'.
6325 This removes the need for the NO_ABORT configure-time macro
6326 and makes it easier to change the abort code to do a backtrace.
6327 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6328 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6329 Remove; sysdep.c's emacs_abort now takes its place.
6330 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6331 'abort' changed to use 'emacs_abort'.
6332 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6333 (abort) [!defined abort]: Rename to ...
6334 (emacs_abort): ... new name.
6335 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6336 the place of the old 'abort' in emacs.c.
6337 * w32.c, w32fns.c (abort): Do not #undef.
6338 * w32.c (emacs_abort): Rename from w32_abort.
6340 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6342 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6343 offsets[j].dv, since the y axis of the screen coordinates points
6344 down, while the y axis of the font definition coordinates points
6345 up. This fixes display of Arabic diacritics such as KASRA and
6346 KASRATAN. (Bug#11860)
6348 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6350 Be more systematic about _setjmp vs setjmp.
6351 * alloc.c (test_setjmp, mark_stack):
6352 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6353 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6354 (png_load, my_error_exit, jpeg_load):
6355 * process.c (send_process_trap, send_process):
6356 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6357 The underscored versions are up to 30x faster on some hosts.
6358 Formerly, the code used setjmp+longjmp sometimes and
6359 _setjmp+_longjmp at other times, with no particular reason to
6360 prefer setjmp+longjmp.
6362 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6364 Fix minor problem found by static checking.
6365 * buffer.c (Fdelete_all_overlays): Return nil.
6367 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6369 * buffer.c (Fdelete_all_overlays): New function.
6371 2012-09-03 Chong Yidong <cyd@gnu.org>
6373 * gtkutil.c: Add extern decl for Qxft.
6375 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6377 * emacs.c, eval.c: Use bool for boolean.
6378 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6379 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6380 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6381 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6382 (main, decode_env_path, Fdaemon_initialized):
6383 * eval.c (call_debugger, Finteractive_p, interactive_p):
6384 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6385 (maybe_call_debugger, Fbacktrace):
6386 * process.c (read_process_output, exec_sentinel):
6387 Use bool for booleans.
6388 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6389 All callers changed.
6390 * eval.c (interactive_p): Omit always-true boolean argument
6391 EXCLUDE_SUBRS_P. All callers changed.
6392 * dispextern.h, lisp.h: Reflect above API changes.

6397 * msdos.c (fatal_error_in_progress): ... from here.
6398 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6400 (redisplay_internal, unwind_redisplay): Simply clear
6401 REDISPLAYING_P when unwinding, instead of saving its previous,
6402 always-false value and then restoring it.
6404 Clean up some extern decls.
6405 Mostly, this hoists extern decls out of .c files and into .h files.
6406 That way, we're more likely to catch errors if the interfaces change.

6492 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6493 more than one grapheme cluster passed to the shaper: compute the
6494 offset adjustment values separately for each cluster. (Bug#11860)
6496 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6497 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6498 about implicit conversions from integer to pointer.
6500 2012-09-01 Daniel Colascione <dancol@dancol.org>
6502 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

6556 window system declarations.
6558 * frame.h: Move common functions here: set_frame_menubar,
6559 x_set_window_size, x_sync, x_get_focus_frame,
6560 x_set_mouse_position, x_set_mouse_pixel_position,
6561 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6622 * lread.c (init_lread): For out-of-tree builds, only add the
6623 source directory's site-lisp dir to the load-path if it exists,
6624 consistent with in-tree builds. (Bug#12302)

6647 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6648 Add window_closed and button_values. Add void as return value for
6649 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6650 Add process_dialog as new member.

6840 (string_escape_byte8):
6841 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6842 (load_charset_map_from_file, map_charset_chars)
6843 (Fdefine_charset_internal, define_charset_internal)
6844 (Fdeclare_equiv_charset, find_charsets_in_text)
6845 (Ffind_charset_region, char_charset, Fiso_charset):
6846 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6847 (sub_char_table_set, sub_char_table_set_range)
6848 (char_table_set_range, optimize_sub_char_table)
6849 (map_sub_char_table):
6850 Use bool for boolean.
6851 * character.c (str_to_unibyte): Omit last boolean argument; it was
6852 always 0. All callers changed.
6853 * character.h, charset.h: Adjust to match previous changes.
6854 * character.h (char_printable_p): Remove decl of nonexistent function.
6855 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6856 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6857 are all boolean, so make them single-bit bitfields.
6859 * lisp.h (ASET): Remove attempt to detect side effects.
6860 It was meant to be temporary and it often doesn't work,
6861 because when IDX has side effects the behavior of IDX==IDX
6862 is undefined. See Stefan Monnier in
6863 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6865 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6867 * lisp.h (functionp): New function (extracted from Ffunctionp).
6868 (FUNCTIONP): Use it.
6869 * eval.c (Ffunctionp): Use it.
6871 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6873 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6874 as that's faster and simpler than static storage. Don't bother
6875 with the g_main_context_query overhead if g_main_context_pending
6876 says no events are pending.
6877 (gfds, gfds_size): Remove these static vars.
6878 (xgselect_initialize): Remove; no longer needed.
6879 All uses and decls removed.
6881 * emacs.c (fatal_error_signal_hook): Remove.
6882 All uses removed. This leftover from old code was always 0.
6884 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6885 * casefiddle.c (casify_object, casify_region):
6886 * casetab.c (set_case_table):
6887 * category.c, category.h (word_boundary_p):
6888 * category.h (CHAR_HAS_CATEGORY):
6889 Use bool for booleans, instead of int.
6891 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6893 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6895 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6897 On assertion failure, print backtrace if available.
6898 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6899 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6900 * Makefile.in (LIB_EXECINFO): New macro.
6903 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6904 * bytecode.c (exec_byte_code):
6905 * callint.c (check_mark, Fcall_interactively):
6906 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6907 (getenv_internal, sync_process_alive, call_process_exited):
6908 * lisp.h (USE_SAFE_ALLOCA):
6909 Use bool for booleans, instead of int.
6910 * lisp.h, process.h: Adjust prototypes to match above changes.
6911 * callint.c (Fcall_interactively): Don't assume the mark's
6912 offset fits in 'int'.
6914 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6916 * buffer.c, buffer.h: Use bool for boolean.
6917 * buffer.c (reset_buffer_local_variables)
6918 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6919 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6920 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6921 (overlay_touches_p, overlay_strings, Foverlay_put)
6922 (report_overlay_modification, call_overlay_mod_hooks):
6923 (mmap_enlarge, mmap_set_vars):
6924 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6925 Use bool for booleans, instead of int.
6926 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6927 since the 1-or-0 return value is always ignored anyway.
6928 (mmap_initialized_p):
6929 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6930 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6932 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6934 * bidi.c: Use bool for boolean.
6935 This is a bit more readable, and makes the text segment of bidi.o
6936 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6937 Presumably it's faster too.
6938 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6940 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6941 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6942 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6943 (bidi_explicit_dir_char, bidi_level_of_next_char)
6944 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6945 Use bool for booleans, instead of int.
6946 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6947 (bidi_unshelve_cache): Adjust decls to match code.
6949 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6951 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6954 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6956 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6957 * atimer.h: Include <stdbool.h>.
6959 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6961 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6962 compile time tests instead of run time tests on systems that do
6964 (FRAME_MAC_P): Remove leftover from deleted code.
6965 * frame.c (syms_of_frame): Remove leftover from deleted code.
6967 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6969 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6971 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6973 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6974 Otherwise, the compiler complains about (A?B:C) where B is void
6975 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6976 (fontset_add): Return void, for FONTSET_ADD.
6978 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6980 * alloc.c: Use bool for booleans.
6981 (gc_in_progress, abort_on_gc)
6982 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6983 (dont_register_blocks) [GC_MALLOC_CHECK]:
6984 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6985 (check_string_bytes, make_specified_string, memory_full)
6986 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6987 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6988 (mark_stack, valid_pointer_p, make_pure_string)
6989 (Fgarbage_collect, survives_gc_p, gc_sweep):
6990 Use bool for booleans, instead of int.
6991 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6992 Remove unused local.
6993 * alloc.c (PURE_POINTER_P):
6994 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6995 * editfns.c (Fformat):
6996 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6998 * fns.c (sweep_weak_table):
6999 * lisp.h (suppress_checking, push_message, survives_gc_p)
7000 (make_pure_string, gc_in_progress, abort_on_gc):
7001 * lread.c (readchar, read1):
7002 * print.c (Fprin1_to_string):
7003 * xdisp.c (push_message):
7004 Use bool for booleans affected directly or indirectly by
7007 Make recently-introduced setters macros.
7008 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7009 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7010 (set_fontset_default, set_fontset_fallback): Rename from their
7011 upper-case counterparts, and make them functions rather than macros.
7012 This is more consistent with the other recently-introduced setters.
7013 These don't need to be inline, since they're local.
7015 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7017 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7018 the loop (Bug#12247).
7020 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7022 * lisp.h (vcopy): Use memcpy rather than our own loop.
7023 This fixes a performance regression introduced by the recent
7024 addition of vcopy. This means 'vcopy' will need to be modified
7025 for a copying collector, but that's OK. Also, tighten the
7026 checking in the assertion.
7028 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7030 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7031 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7032 non-base glyph for the width of the base character, according to
7033 what x_draw_composite_glyph_string_foreground expects.
7034 Generate WADJUST value according to composition_gstring_width's
7035 expectations, to produce correct width of the composed character.
7036 Reverse the sign of the DU offset produced by ScriptPlace.
7038 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7040 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7042 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7044 Avoid direct writes to contents member of struct Lisp_Vector.
7045 * lisp.h (vcopy): New function to copy data into vector.
7046 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7047 * fns.c (Ffillarray): Use ASET.
7048 * keyboard.c (timer_check_2): Use AREF and ASET.
7049 (append_tool_bar_item, Frecent_keys): Use vcopy.
7050 * lread.c (read_vector): Use ASET.
7051 * msdos.c (Frecent_doskeys): Use vcopy.
7052 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7053 (Finternal_merge_in_global_face): Use ASET and vcopy.
7054 * xfont.c (xfont_list_pattern): Likewise.
7056 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7058 * window.c (Fwindow_point): For the selected window always return
7059 the position of its buffer's point.
7060 (Fset_window_point): For the selected window always go in its
7061 buffer to the specified position.
7063 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7065 Setter macros for fontsets.
7066 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7067 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7068 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7071 2012-08-20 Glenn Morris <rgm@gnu.org>
7073 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7074 Don't assume that `ln -f' works.
7076 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7078 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7079 and later about non-assignments with no effect. See discussion at
7080 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7083 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7085 Inline setter functions for Lisp_Objects slots of struct specbinding.
7086 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7089 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7091 * window.c (select_window): Always make selected window's buffer
7094 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7096 Use AREF and ASET for docstrings of category tables.
7097 * category.h (CATEGORY_DOCSTRING): Use AREF.
7098 (SET_CATEGORY_DOCSTRING): Use ASET.
7099 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7101 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7103 Inline setter functions for hash table members.
7104 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7105 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7106 (set_hash_key_and_value, set_hash_index, set_hash_next)
7107 (set_hash_hash): New functions.
7108 * charset.c, fns.c: Adjust users.
7110 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7112 Inline getter and setter functions for per-buffer values.
7113 * buffer.h (per_buffer_default, set_per_buffer_default)
7114 (per_buffer_value, set_per_buffer_value): New functions.
7115 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7116 * buffer.c, data.c: Adjust users.
7118 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7120 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7122 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7124 Rely on <config.h> + <unistd.h> to declare 'environ',
7125 as gnulib does this if the system doesn't.
7126 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7127 Remove declaration. MS-Windows declares it on stdlib.h which is
7128 included by conf_post.h.
7129 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7130 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7131 * vm-limit.c: Include <unistd.h>, for 'environ'.
7133 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7134 (start_of_data): Remove decl; mem-limits.h provides it.
7136 * xdisp.c (handle_invisible_prop): Make it a bit faster
7137 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7139 2012-08-19 Chong Yidong <cyd@gnu.org>
7141 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7144 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7146 * .gdbinit: Use call instead of set when calling a function in the
7149 * data.c (set_internal): Don't use set_blv_found.
7150 (Fkill_local_variable): Likewise.
7152 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7154 * nsfont.m (ns_ascii_average_width): Ensure the string
7155 ascii_printable is initialized with a null-terminated character
7156 array. Otherwise, it can contain undesired extra characters.
7158 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7160 port new setting code to Sun C 5.8 2005/10/13
7161 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7162 Return void, not Lisp_Object. Otherwise, the compiler
7163 complains about (A?B:C) where B is void and C is Lisp_Object
7164 when compiling CHAR_TABLE_SET, due to the recent change to
7165 the API of sub_char_table_set_contents.
7167 2012-08-18 Chong Yidong <cyd@gnu.org>
7169 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7170 for the string case (Bug#3874).
7172 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7174 * buffer.h (BSET): Remove (Bug#12215).
7175 Replace all uses with calls to new setter functions.

7244 New setter functions.
7246 * termhooks.h (TSET): Remove (Bug#12215).
7247 Replace all uses with calls to new setter functions.
7248 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7249 (TERMHOOKS_INLINE): New macro.
7250 (tset_charset_list, tset_selection_alist): New setter functions.
7251 * terminal.c (TERMHOOKS_INLINE):
7252 Define to EXTERN_INLINE, so that the corresponding functions
7253 are compiled into code.
7254 (tset_param_alist): New setter function.
7256 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
7258 * keyboard.h (KSET): Remove (Bug#12215).
7259 Replace all uses with calls to new setter functions.

8002 value of EMACSLOADPATH, as it is no longer needed.
8003 (check_windows_init_file): Now external, not static.
8004 Use Vload_path as is, without adding anything, as this function is now
8005 called when Vload_path is already set up.

8009 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8054 * alloc.c (record_xmalloc): New function.
8055 * lisp.h (record_xmalloc): New decl.
8056 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8057 more like a function. This is because the pointer cast is not
8058 needed. All uses changed.
8059 * print.c (print_string, print_error_message): Avoid length recalc.
8061 Improve fix for macroexp crash with debugging (Bug#12118).
8062 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8063 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8064 not supposed to be invoked from the garbage collector.

8066 (gc_aset): New function, which is like ASET but can be
8067 used in the garbage collector.

8096 with addition of handling of symlinks and support for 'lstat'.
8097 If possible, get file's attributes and security information by
8098 handle, not by name. Produce S_IFLNK bit for symlinks, when
8099 called from 'lstat'.
8100 (stat, lstat): New functions, call 'stat_worker'.
8101 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8102 symlinks when the underlying filesystem supports them.
8104 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8106 Fix macroexp crash on Windows with debugging (Bug#12118).
8107 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8108 checking subscripts; problem introduced with the recent
8109 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8110 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8111 since it's used in non-static inline functions now.
8113 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

8606 arms of an 'if', not using conditional expressions; otherwise GDB
8607 complains about the types in the unevaluated arm when the argument
8608 is an integer literal.
8609 (xgetint): Simplify expression.
8610 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8611 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8612 Zaretskii in <http://bugs.gnu.org/12036#13>.
8613 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8614 needed now that we have gdb_make_enums_visible.
8615 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8616 (enum enum_USE_LSB_TAG):
8617 New enum types, packaging up enums that need to be exported to GDB.
8619 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8621 Utility function to make a list from specified amount of objects.

8635 * xdisp.c (syms_of_xdisp): Likewise.
8636 * xfns.c (syms_of_xfns): Likewise.
8638 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8640 Fast save_excursion_save and save_excursion_restore.
8641 * lisp.h (struct Lisp_Excursion): New data type.
8642 (PVEC_EXCURSION): New pseudovector type.
8643 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8644 to deal with it. Adjust comments.
8645 (init_marker, attach_marker): New prototype.
8646 (unchain_marker): Adjust prototype.
8647 * marker.c (attach_marker): Change to global.

8655 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8657 Fix export of symbols to GDB (Bug#12036).
8658 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8659 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8660 emacs.c, as this is a more-suitable home. Had this been done earlier
8661 the fix for 12036 would have avoided some of the problems noted in
8662 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8663 would have been more obvious.
8664 * emacs.c: Do not include <verify.h>; no longer needed.
8665 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8666 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8667 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8668 Remove; now done in lisp.h.
8669 * lisp.h (PUBLISH_TO_GDB): New macro.
8670 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8671 (DATA_SEG_BITS): Use it.
8672 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8673 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8674 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8675 not be usable in #if. This simplifies things.
8677 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8679 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8681 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8683 Simplify export of symbols to GDB (Bug#12036).
8684 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8685 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8686 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8687 Adjust to changes in lisp.h and emacs.c, by using
8688 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8689 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8690 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8691 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8692 instead of gdb_valbits.
8693 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8694 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8695 instead of gdb_array_mark_flag.
8696 (xboolvector): Get size from $->size, not $->header.size.
8697 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8698 (xreload, hook-run, hookpost-run): Remove.
8699 * emacs.c: Include <verify.h>.
8700 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8701 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8703 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8704 (gdb_USE_LSB_TAG): New enum constants.
8705 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8706 Also define these as enum constants, so they're visible to GDB.
8707 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8708 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8709 as constants, so they're visible to GDB.
8710 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8711 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8712 Now enum constants, not macros, so they're visible to GDB.
8713 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8714 more convenient now. All uses changed.
8715 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8716 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8718 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8725 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8726 add argument, tune behavior, and adjust all callers.
8728 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8730 Use typedef for EMACS_INT, EMACS_UINT.
8731 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8732 than macros. This simplifies debugging in the usual case, since
8733 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8734 and it allows expressions involving EMACS_INT casts.
8735 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8737 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8745 that FOCUS-FRAME can be omitted.
8747 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8749 Adjust buffer text indirection counters at the end of Fkill_buffer.
8750 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8751 buffer is definitely dead. This should really fix an issue reported
8752 by Christoph Scholtes again. (Bug#12007).
8753 (init_buffer_once): Initialize indirection counters of
8754 buffer_defaults and buffer_local_symbols (for sanity and safety).
8756 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8758 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8759 and continuation glyphs on tooltip frames, leave them at zero.
8760 Avoids continued lines in tooltips. (Bug#11832)
8762 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

8787 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8789 Swap buffer text indirection counters in Fbuffer_swap_text.
8790 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8791 This avoids crash reported by Christoph Scholtes at
8792 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8794 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8796 * nsmenu.m (Popdown_data): New struct.

8801 and autorelease them. Also autorelease img and matrix (Bug#12005).
8802 (dealloc): Remove (Bug#12005).

8819 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8821 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8822 as it's limited by the amount of memory, not by INT_MAX.
8824 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8826 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8827 in special-event-map. See the discussion at

8886 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8887 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8888 Adjust users accordingly.
8889 * font.h (font_open_by_name): Adjust prototype.

8908 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8909 'for_each_per_buffer_object_at'.
8910 All uses changed. It's better to use upper-case for macros that
8911 cannot be implemented as functions, to give the reader a clue
8912 that they're special.
8914 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

8957 * intervals.c (merge_interval_right, merge_interval_left):
8958 Do not zero out this interval if it is absorbed by its children,
8959 as this interval's total length doesn't change in that case. See
8960 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8962 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8964 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8965 when invoking (make-bool-vector N t) and N is a positive

8973 padding before the data member of a bool vector.
8974 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
8975 than doing the check by hand with an abort ().
8977 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8979 * eval.c (Fdefvar): Don't check constants since we only set the var if
8980 it's not yet defined anyway (bug#11904).
8982 * lisp.h (last_undo_boundary): Declare new var.
8983 * keyboard.c (command_loop_1): Set it.
8984 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8985 were auto-added by the command loop (bug#11774).
8987 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
8989 * w32font.c (Qsymbol): Remove local definition.

9490 * s/gnu.h: Remove file, which is now empty.
9492 * s/gnu.h, s/gnu-linux.h:
9493 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
9495 2012-07-11 John Wiegley <johnw@newartisans.com>
9497 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9498 function attribute, so we only use it if it exists in the
9501 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9503 Avoid call to strlen in fast_c_string_match_ignore_case.
9504 * search.c (fast_c_string_match_ignore_case): Change to use
9505 length argument. Adjust users accordingly.
9506 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
9508 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

9549 Remove "#define unix" that is no longer needed (Bug#11905).
9550 * s/aix4-2.h (unix): Remove; no longer needed.
9552 EMACS_TIME simplification (Bug#11875).
9553 This replaces macros (which typically do not work in GDB)
9554 with functions, typedefs and enums, making the code easier to debug.
9555 The functional style also makes code easier to read and maintain.
9556 * systime.h: Include <sys/time.h> on all hosts, not just if
9557 WINDOWSNT, since 'struct timeval' is needed in general.
9558 (EMACS_TIME): Now a typedef, not a macro.
9559 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9561 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9564 (EMACS_TIME_LE): Now functions, not macros.
9565 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9566 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9567 which are not functions. All uses rewritten to use:
9568 (make_emacs_time): New function.
9569 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9570 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9571 not functions. All uses rewritten to use the following, respectively:
9572 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9573 (add_emacs_time, sub_emacs_time): New functions.
9574 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9575 * fileio.c (Fcopy_file):
9576 * xterm.c (XTflash): Get the current time closer to when it's used.
9577 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9584 * frame.c (Fmake_terminal_frame):
9585 * gtkutil.c (get_utf8_string):
9587 * nsmenu.m (ns_update_menubar):
9588 * regex.c (regerror):
9589 Prefer memcpy to strncpy and strncat when either will do.
9590 * fileio.c (Fsubstitute_in_file_name):
9591 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9592 (menu_separator_name_p):
9593 * nsmenu.m (ns_update_menubar):
9594 Prefer memcmp to strncmp when either will do.
9595 * nsterm.m: Include <ftoastr.h>.
9597 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9598 Prefer snprintf to strncpy.
9599 * nsterm.m (ns_term_init):
9600 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9601 * nsterm.m (ns_term_init):
9602 Avoid the need for strncpy, by using build_string or
9603 make_unibyte_string directly. Use dtoastr, not snprintf.
9604 * process.c (Fmake_network_process): Diagnose service names that
9605 are too long, rather than silently truncating them or creating
9606 non-null-terminated names.
9607 (Fnetwork_interface_info): Likewise, for interface names.
9608 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9609 Prefer sprintf to strncat.
9610 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9611 Prefer vsnprintf to vsprintf + strncpy.
9613 2012-07-10 Glenn Morris <rgm@gnu.org>
9615 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9616 Clarify fallback case.
9618 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9620 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9621 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9622 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9623 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9624 where argument type is known to be a Lisp_Cons.
9626 2012-07-10 Tom Tromey <tromey@redhat.com>
9628 * bytecode.c (BYTE_CODE_THREADED): New macro.
9629 (BYTE_CODES): New macro. Replaces all old byte-code defines.
9630 (enum byte_code_op): New type.

9634 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9636 Optimize pure C strings initialization.
9637 * lisp.h (make_pure_string): Fix prototype.
9638 (build_pure_c_string): New function, defined as static inline. This
9639 provides a better opportunity to optimize away calls to strlen when
9640 the function is called with compile-time constant argument.
9641 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9642 argument, adjust users accordingly. Use build_pure_c_string where
9644 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9645 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9646 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9648 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9650 Avoid calls to strlen in miscellaneous functions.
9651 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9652 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9653 * lread.c (openp): Likewise.
9655 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9657 Avoid calls to strlen in path processing functions.
9658 * fileio.c (file_name_as_directory): Add comment. Change to add
9659 srclen argument and return the length of result. Adjust users
9661 (directory_file_name): Fix comment. Change to add srclen argument,
9662 swap 1st and 2nd arguments to obey the common convention.
9663 Adjust users accordingly.
9664 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9666 2012-07-10 Glenn Morris <rgm@gnu.org>
9668 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9669 Move PENDING_OUTPUT_COUNT definition to configure.
9671 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9672 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9673 * s/gnu.h (DATA_START): Move definitions to configure.
9675 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9676 We include usg5-4-common.h, which defines them both.
9678 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9679 O_RDONLY already includes it).
9681 Stop ns builds setting the EMACSLOADPATH environment variable.
9682 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9683 Now it does not set EMACSLOADPATH, just returns the load-path string.
9684 * nsterm.h: Update accordingly.
9685 * lread.c [HAVE_NS]: Include nsterm.h.
9686 (init_lread) [HAVE_NS]: Use ns_load_path.
9687 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9689 2012-07-09 Glenn Morris <rgm@gnu.org>
9691 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9692 since the included bsd-common.h does so.
9694 Stop ns builds setting the EMACSPATH environment variable.
9695 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9696 (ns_init_paths): Do not set EMACSPATH.
9697 * nsterm.h (ns_exec_path): Add it.
9698 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9701 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9703 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9705 * process.c (wait_reading_process_output): 'waitchannels' was unset
9706 when read_kbd || !NILP (wait_for_cell); fix this.
9708 Add GCC-style 'const' attribute to functions that can use it.
9709 * character.h (char_resolve_modifier_mask):
9710 * keyboard.h (make_ctrl_char):
9711 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9712 (init_character_once, next_almost_prime, init_fns, init_image)
9713 (flush_pending_output, init_sound):
9714 * mem-limits.h (start_of_data):

9718 Declare the dummy function with ATTRIBUTE_CONST.
9719 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9720 Add decls with ATTRIBUTE_CONST.
9722 Minor improvements to make_formatted_string.
9723 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9724 where int is good enough, as vsprintf returns an int.
9725 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9727 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9729 Use make_formatted_string to avoid double length calculation.
9730 * lisp.h (make_formatted_string): New prototype.

9736 * frame.c (make_terminal_frame, set_term_frame_name)
9737 (x_report_frame_params): Likewise.
9738 * image.c (gs_load): Likewise.
9739 * minibuf.c (get_minibuffer): Likewise.

9754 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9756 Move marker debugging code under MARKER_DEBUG.
9757 * marker.c (MARKER_DEBUG): Move marker debugging code under
9758 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9759 for bootstrap with --enable-checking (~3x slowdown reported
9760 by Juanma Barranquero <lekktu@gmail.com>).
9761 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9763 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9765 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9766 See <http://bugs.gnu.org/11825#29>.
9768 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9770 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9771 has no font, use the frame's font. (Bug#11813)
9772 (display_line): Add commentary about displaying truncation glyphs
9774 (produce_special_glyphs): Move here from term.c.
9776 * term.c (produce_special_glyphs): Move to xdisp.c.
9778 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9781 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9783 * xdisp.c (display_line): Avoid warning about implicit declaration
9786 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9788 * lisp.h: Remove empty conditional.
9790 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9792 * lread.c (load_path_check): Now static.
9794 Fix some minor --with-ns problems found by static checking.
9795 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9796 (x_set_font) [!HAVE_X_WINDOWS]:
9797 * image.c (xpm_load_image) [HAVE_NS]:
9798 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9799 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9800 Remove unused local.
9801 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9802 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9803 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9804 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9805 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9806 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9807 Fix pointer signedness problem.
9808 * xfaces.c (FRAME_X_FONT_TABLE):
9809 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9811 2012-07-07 Glenn Morris <rgm@gnu.org>
9813 * lread.c (load_path_check): New function, split from init_lread.
9814 (init_lread): Reorganize. Motivation:
9815 If EMACSLOADPATH is set, check/warn about that rather than the
9816 defaults, which we are not going to use. Hence we can remove
9817 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9818 Don't warn if site-lisp directories are missing.
9819 If not installed, start from a blank load-path, since
9820 PATH_LOADSEARCH refers to the eventual installation directories.
9822 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9824 Support truncation and continuation glyphs on GUI frames, when
9825 fringes are disabled. (Bug#11832)
9826 * xdisp.c (init_iterator): Get dimensions of truncation and
9827 continuation glyphs even if on GUI frames.
9828 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9829 or both, are absent.
9830 (start_display, move_it_in_display_line_to): Handle the case of a
9831 GUI frame without a fringe to display continuation or truncation
9833 (insert_left_trunc_glyphs): Support GUI frames: make sure
9834 truncation glyphs overwrite enough glyphs from the current line to
9835 have sufficient space in pixels.
9836 (display_line): Support truncation and continuation glyphs on GUI
9837 frames. If some spare pixels are left on the line after inserting
9838 the truncation glyphs, fill that space with a stretch glyph of a
9839 suitably computed width.
9841 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9842 produce_glyphs, to support GUI sessions.
9844 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9846 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9848 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9850 Do not require float-time's arg to fit in time_t (Bug#11825).
9851 This works better on hosts where time_t is unsigned, and where
9852 float-time is applied to the (negative) difference between two times.
9853 * editfns.c (decode_time_components): Last arg is now double *,
9854 not int *, and means to store all the result as a double, without
9855 worrying about whether the seconds part fits in time_t.
9856 All callers changed.
9857 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9858 All callers changed.
9859 (Ffloat_time): Do not fail merely because the specified time falls
9860 outside of time_t range.
9862 2012-07-07 Glenn Morris <rgm@gnu.org>
9864 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9868 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9870 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9871 Update dependencies.
9873 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9875 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9877 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9878 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9879 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9880 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9881 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9882 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9884 * xfont.c (compare_font_names): Redo to omit the need for casts.
9886 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9888 * xfns.c (Fx_change_window_property): Doc fix.
9889 * w32fns.c (Fx_change_window_property): Doc fix.
9891 * w32fns.c (Fx_window_property): Accept the same arguments as the
9892 X Windows version. Doc fix.
9893 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9895 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9896 Eli Zaretskii <eliz@gnu.org>
9898 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9899 Windows-specific code from nt/config.nt moved here.
9900 Obsolete settings removed.
9902 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9904 * process.c: Avoid unnecessary calls to gettime.
9905 (wait_reading_process_output): Don't get the time of day
9906 when gobbling data immediately and not waiting, as there's no need
9907 for it in that case. This removes a FIXME.
9909 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9911 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9912 is defined (Bug#11768).
9914 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9916 Fix marker debugging code.
9917 * marker.c (byte_char_debug_check): Do not perform the check
9918 if buffer is not multibyte.
9919 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9920 Call byte_char_debug_check with correct arguments.
9922 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9924 Compile marker debugging code only if ENABLE_CHECKING is defined.
9925 * marker.c (byte_char_debug_check, count_markers):
9926 Use only if ENABLE_CHECKING is defined.
9927 (byte_debug_flag): Remove.
9928 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9929 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9931 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9933 Avoid code repetition in marker-related functions.
9934 * marker.c (attach_marker): New function.
9935 (Fset_marker, set_marker_restricted, set_marker_both)
9936 (set_marker_restricted_both): Use it.
9937 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9938 Consistently rename charno to charpos.
9939 (marker_position): Add eassert.
9940 (marker_byte_position): Convert to eassert.

9952 * lisp.h (build_marker): New prototype.
9953 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9954 * composite.c (autocmp_chars): Likewise.
9955 * editfns.c (buildmark): Remove.
9956 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9957 (save_restriction_save): Use build_marker.
9958 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9959 * window.c (save_window_save): Likewise.
9961 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9963 Do not use Fdelete_overlay in delete_all_overlays
9964 to avoid redundant calls to unchain_overlay.
9965 * buffer.c (drop_overlay): New function.
9966 (delete_all_overlays, Fdelete_overlay): Use it.
9967 * minibuf.c (get_minibuffer): Fix comment.
9969 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9971 Port to OpenBSD 5.1 amd64.
9972 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9973 This is needed for OpenBSD, and should be harmless on all BSD systems.
9974 Also, include <sys/sysctl.h>, as it should be available on all
9975 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9976 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9977 use p_pid member, not kp_proc.pid.
9979 2012-07-06 Glenn Morris <rgm@gnu.org>
9981 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9983 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9985 More xmalloc and related cleanup.
9986 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9994 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9996 Omit needless casts involving void * pointers and allocation.
9997 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9998 as the former is more robust if P's type is changed.
9999 Prefer xzalloc to xmalloc + memset 0.
10000 Simplify malloc-or-realloc to realloc.
10001 Don't worry about xmalloc returning a null pointer.
10002 Prefer xstrdup to xmalloc + strcpy.
10003 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10005 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10006 alloca of a constant.
10008 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10010 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10011 hscroll is larger than the line width. Fixes long and futile
10012 looping inside extend_face_to_end_of_line (on a TTY) producing
10013 glyphs that are not needed and thrown away.
10015 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10017 * marker.c (set_marker_restricted_both): Simplify by using
10020 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10022 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10024 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10026 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10027 not defined (Bug#11768).
10028 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10029 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10030 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10031 followed by gtk_box_set_homogeneous (Bug#11768).
10032 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10033 (update_theme_scrollbar_width, xg_create_scroll_bar):
10034 Use gtk_scrollbar_new (Bug#11768).

10036 (is_box_type): New function (Bug#11768).
10037 (xg_tool_item_stale_p): Call is_box_type.
10038 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10039 with default display (Bug#11768).
10041 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10043 * xdisp.c (window_hscroll_limited): New function.
10044 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10045 coordinates when window's hscroll is set to insanely large
10046 values. (Bug#11857)
10048 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10109 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10111 * fileio.c (time_error_value): Check the right error number.
10112 Problem reported by Troels Nielsen in
10113 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10115 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10117 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10118 This should be fixed in a better way; see Eli Zaretskii in
10119 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10120 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10122 * fileio.c (time_error_value): Rename from special_mtime.
10123 The old name's problems were noted by Eli Zaretskii in
10124 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10126 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10127 This variable's comment says Emacs needs at least one GDB-visible
10128 symbol of type enum pvec_type, to work around GDB problems.
10129 The symbol's value doesn't matter.
10131 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10132 that causes compilation to fail on pre-C99 compilers.
10134 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10136 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10137 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10139 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10141 * buffer.c (init_buffer_once): Fix initialization of
10142 headers for buffer_defaults and buffer_local_symbols.
10143 Reported by Juanma Barranquero <lekktu@gmail.com>.
10145 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10147 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10148 * lisp.h (enum pvec_type): Use fewer bits.
10149 (PSEUDOVECTOR_SIZE_BITS): New constant.
10150 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10151 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10152 change in pvec_type.
10153 (PSEUDOVECTOR_TYPEP): New macro.
10154 (TYPED_PSEUDOVECTORP): Use it.
10155 * fns.c (internal_equal): Adapt code to extract pvectype.
10156 * emacs.c (gdb_pvec_type): Update type.
10157 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10158 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10159 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10160 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10161 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10162 abusing vector->header.next.nbytes.
10163 (live_vector_p): Use PVEC_TYPE.
10164 (mark_object): Adapt code to extract pvectype. Use switch.
10166 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10168 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10169 Tighten new eassert a bit.
10171 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10173 Fix compilation with --enable-gcc-warnings and -O1
10174 optimization level.
10175 * doprnt.c (doprnt): Change type of tem to int, initialize
10176 to avoid compiler warning. Add eassert.
10177 * search.c (simple_search): Initialize match_byte to avoid
10178 compiler warning. Add eassert.
10180 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10182 Avoid weird behavior with large horizontal scrolls.
10183 Without this change, for example, large hscroll values would
10184 mess up Emacs's display on Fedora 15 x86, presumably due to
10185 overflows in int calculations in the display code.
10186 Also, if buffers had long lines, Emacs would freeze.
10187 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10188 (set_window_hscroll): New function, containing the old guts of
10189 Fset_window_hscroll. Return the clipped value.
10190 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10191 This avoids the need to check against PTRDIFF_MAX.
10193 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10195 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10197 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10199 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10201 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10202 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10203 since GCC 4.4.6 issues a bogus warning for them.
10205 Fix bugs in file timestamp newness comparisons.
10206 * fileio.c (Ffile_newer_than_file_p):
10207 * lread.c (Fload): Use full timestamp resolution of files,
10208 not just the 1-second resolution, so that files that are only
10209 slightly newer still count as newer.
10210 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10211 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10213 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10215 * fileio.c: Improve handling of file time marker. (Bug#11852)
10216 (special_mtime): New function.
10217 (Finsert_file_contents, Fverify_visited_file_modtime):
10218 Use it to set special mtime values consistently.
10220 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10222 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10223 marker for non-existing file. (Bug#11852)
10225 2012-07-03 Glenn Morris <rgm@gnu.org>
10227 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10228 and did not make it into globals.h).
10230 2012-07-03 Tom Tromey <tromey@redhat.com>
10232 * window.c (Fset_window_margins, Fset_window_fringes)
10233 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10234 * textprop.c (Fprevious_property_change): No longer static.
10235 * syntax.c (Fsyntax_table_p): No longer static.

10259 * font.h: Remove EXFUNs.
10260 * dosfns.c (system_process_attributes): Remove EXFUN.
10261 * keymap.h: Remove EXFUNs.
10262 * lisp.h: Remove EXFUNs.
10263 * w32term.h: Remove EXFUNs.
10264 * window.h: Remove EXFUNs.
10265 * xsettings.h: Remove EXFUN.
10266 * xterm.h: Remove EXFUN.
10268 2012-07-03 Glenn Morris <rgm@gnu.org>
10270 * lisp.h (Frandom): Make it visible to C.
10271 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10272 buffer for invisible buffers. (Bug#1229)
10274 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10276 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10277 values which aren't power of 2.
10278 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10279 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10282 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10284 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10286 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10288 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10290 * alloc.c (allocate_vector_block): Remove redundant
10291 calls to mallopt if DOUG_LEA_MALLOC is defined.
10292 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10293 avoid calls to mallopt if zero_vector is returned.
10295 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10297 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10298 is enabled, avoid dereferencing NULL current_sblock if
10301 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10303 Cleanup basic buffer management.
10304 * buffer.h (struct buffer): Change layout to use generic vector
10305 marking code. Fix some comments. Change type of 'clip_changed'
10306 to bitfield. Remove unused #ifndef old.
10307 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10308 (GET_OVERLAYS_AT): Fix indentation.
10309 (for_each_per_buffer_object_at): New macro.
10310 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10311 (Fbuffer_local_variables): Use it.
10312 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10313 * alloc.c (allocate_buffer): Adjust to match new layout of
10314 struct buffer. Fix comment.
10315 (mark_overlay): New function.
10316 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10317 Lisp area of struct buffer.
10318 (mark_object): Use it. Adjust marking of misc objects
10319 and related comments.
10321 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10323 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10324 wrapper that is not needed because the wrapped code is a no-op (zero
10325 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10326 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10328 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10330 * alloc.c (mark_buffer): Simplify. Remove prototype.
10331 (mark_object): Add comment. Reorganize marking of vector-like
10332 objects. Use CHECK_LIVE for all vector-like objects except buffers
10333 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10334 Avoid redundant calls to mark_vectorlike for bool vectors.
10336 2012-06-30 Glenn Morris <rgm@gnu.org>
10338 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10340 * epaths.in (PATH_SITELOADSEARCH): New.
10341 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10342 This is rather than relying on --enable-locallisppath elements
10343 having "site-lisp" in their names. (Bug#10208#25, 11658)
10345 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10347 * w32proc.c (sys_select): Accept and ignore one more argument.
10349 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10351 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10352 (pselect) [!MS_DOS]: Redirect to sys_select.
10354 * sysdep.c: Don't include dos.h and dosfns.h.
10356 * process.c (sys_select):
10357 * msdos.c (sys_select): Accept one more argument and ignore it.
10359 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10360 adapt data types and code to that.
10363 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10364 which clashes with the gnulib function of the same name.
10366 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10368 * font.c (font_style_to_value, font_style_symbolic)
10369 (font_prop_validate_style): Add type checks for values in
10372 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10374 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10377 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10379 * xdisp.c (try_window_id): Undo last change.
10381 * w32.c (getwd): Adjust commentary about startup_dir.
10382 (init_environment): Always call sys_access, even in non-MSVC
10383 builds. Don't chdir to the directory of the Emacs executable.
10384 This undoes code from 1997 which was justified by the need to
10385 "avoid conflicts when removing and renaming directories". But its
10386 downside was that every relative file name was being interpreted
10387 relative to the directory of the Emacs executable, which can never
10388 be TRT. In particular, it broke sys_access when called with
10389 relative file names.
10390 (sys_access): Map GetLastError to errno.

10582 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10584 Use sprintf return value instead of invoking strlen on result.
10585 In the old days this wasn't portable, since some sprintf
10586 implementations returned char *. But they died out years ago and
10587 Emacs already assumes sprintf returns int.
10588 Similarly for float_to_string.
10589 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10597 Use sprintf or float_to_string result to avoid need to call strlen.
10598 * data.c (Fnumber_to_string):

10600 * lisp.h, print.c (float_to_string): Now returns int length.
10601 * term.c (produce_glyphless_glyph):
10602 Use sprintf result rather than recomputing it.
10604 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10633 * xfns.c (x_window): Remove redundant cast.
10635 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10637 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10640 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10642 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10643 instead of truncating it to 63 (admittedly a generous limit).
10645 * process.c: Fix spelling and caps in comments.

10703 * keyboard.c (kbd_buffer_get_event):
10704 * process.c (Faccept_process_output):
10705 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10706 This improves on the previous patch, which introduced a bug
10707 when time_t is unsigned and as wide as intmax_t.
10708 See <http://bugs.gnu.org/9000#51>.
10710 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10739 language ID in the event parameters.
10741 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10742 event.code, not the obscure "character set ID".

10775 Support higher-resolution time stamps (Bug#9000).
10776 The time stamps are only nanosecond-resolution at the C level,
10777 since that's the best that any real-world system supports now.
10778 But they are picosecond-resolution at the Lisp level, as that's
10779 easy, and leaves room for future OS improvements.
10781 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10784 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10785 Don't get current time unless it's needed.
10787 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10788 now provides it if it's absent.
10789 (start_atimer): Port to higher-res time stamps.
10790 Check for time stamp overflow. Don't get current time more
10791 often than is needed.
10793 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10794 Include systime.h, not time.h.
10795 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10797 * dired.c: Include stat-time.h.
10798 (Ffile-attributes): File times now have higher resolution.
10800 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10801 (struct image): Timestamp now has higher resolution.
10803 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10804 has at least microseconds now. All uses removed.
10805 (update_frame, update_single_window, update_window, update_frame_1)
10806 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10807 (duration_to_sec_usec): Remove; no longer needed.
10809 * editfns.c (time_overflow): Now extern.
10810 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10811 (float-time, Fformat_time_string, Fcurrent_time_string)

10814 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10815 (decode_time_components, lisp_seconds_argument): New functions.
10816 (make_time): Now static.
10817 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10818 Report an error if the time is invalid, rather than having the caller
10821 * fileio.c: Include <stat-time.h>
10822 (Fcopy_file): Copy higher-resolution time stamps.
10823 Prefer to set the time stamp via a file descriptor if that works.
10824 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10825 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10826 (Fvisited_file_modtime, Fset_visited_file_modtime):
10827 Support higher-resolution time stamps.
10829 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10831 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10833 * image.c (prepare_image_for_display, clear_image_cache)
10834 (lookup_image): Port to higer-resolution time stamps.
10836 * keyboard.c (start_polling, bind_polling_period):
10837 Check for time stamp overflow.
10838 (read_char, kbd_buffer_get_event, timer_start_idle)
10839 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10840 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10841 Port to higher-resolution time stamps. Do not assume time_t is signed.
10842 (decode_timer): New function. Timers are now vectors of length 9,
10843 not 8, to accommodate the picosecond component.
10844 (timer_check_2): Use it.
10846 * nsterm.m (select_timeout, timeval_subtract): Remove.
10847 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10848 as they're a bit more accurate and handle overflow better.
10849 (ns_select): Change prototype to be compatible with pselect.
10850 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10851 * nsterm.h (ns_select): Adjust prototype.
10853 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10854 us-resolution time stamps.
10855 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10857 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10859 * lisp.h (time_overflow): New decl.

10863 * process.h (struct Lisp_Process.read_output_delay):
10864 Now counts nanoseconds, not microseconds.
10865 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10867 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10868 (wait_reading_process_output):
10869 Port to ns-resolution time stamps.
10870 (Faccept_process_output, wait_reading_process_output):
10871 Check for time stamp overflow. Do not assume time_t is signed.
10872 (select_wrapper): Remove; we now use pselect.
10873 (Fprocess_attributes): Now generates ns-resolution time stamps.
10875 * sysdep.c: Include utimens.h. Don't include utime.h
10876 or worry about struct utimbuf; gnulib does that for us now.
10877 (gettimeofday): Remove; gnulib provides a substitute.
10878 (make_timeval): New function.
10879 (set_file_times): Now sets ns-resolution time stamps.
10880 New arg FD; all uses changed.
10881 (time_from_jiffies, ltime_from_jiffies, get_up_time)

10883 Now returns ns-resolution time stamp. All uses changed.
10884 Check for time stamp overflow.

10887 provides a substitute now.
10889 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10890 since it guarantees struct timespec.
10891 (EMACS_TIME): Now struct timespec, so that we can support
10892 ns-resolution time stamps.
10893 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10894 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10895 (EMACS_USECS): Remove.
10896 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10897 so multiply the arg by 1000 before storing it.

10907 (make_timeval, make_lisp_time, decode_time_components): New decls.
10908 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10909 that it mishandled time_t overflow. You can't compare by subtracting!
10910 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10911 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10913 * term.c: Include <sys/time.h>.
10914 (timeval_to_Time): New function, for proper overflow wraparound.
10915 (term_mouse_position, term_mouse_click): Use it.
10917 * undo.c (record_first_change): Support higher-resolution time stamps
10918 in the undo buffer.
10919 (Fprimitive_undo): Use them when restoring time stamps.
10921 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10922 (w32_get_internal_run_time):
10923 Port to higher-resolution Emacs time stamps.
10924 (ltime): Now accepts single 64-bit integer, as that's more convenient
10927 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10929 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10930 for compatibility with pselect. Support ns-resolution time stamps.
10932 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10934 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10935 Check for time stamp overflow, and support ns-resolution time stamps.
10937 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10938 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10939 (timeval_subtract): Remove; no longer needed.
10940 (XTflash, XTring_bell, x_wait_for_event):
10941 Port to ns-resolution time stamps. Don't assume time_t is signed.

10947 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10949 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10950 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10951 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10952 staticidx goes up to 1597 out of 1600 = 0x640.)
10954 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10956 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10957 Otherwise, the umask might be mistakenly 0 while handling input signals.
10959 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10961 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10977 frame's selected window and its terminal's top-frame.
10978 (unwind_format_mode_line): Restore them.
10979 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10981 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10982 since tty frames can be explicitly named.
10983 (prepare_menu_bars): Likewise.
10985 * term.c (Ftty_top_frame): New function.
10987 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10989 Port byte-code-meter to modern targets.
10990 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10991 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10992 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10993 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11000 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11002 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11003 gets killed during executing of this function (Bug#11665).
11004 Try to always return Qt when the buffer has been actually killed.
11005 (Vkill_buffer_query_functions): In doc-string say that functions
11006 run by this hook should not change the current buffer.
11008 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11010 Fix recently-introduced process.c problems found by static checking.

11030 * lisp.h (eassert): Assume C89 or later.
11031 This removes the need for CHECK.
11032 (CHECK): Remove. Its comments about always evaluating its
11033 argument were confusing, as 'eassert' typically does not evaluate
11036 * coding.c (produce_chars): Use ptrdiff_t, not int.
11038 * xterm.c (x_draw_underwave): Check for integer overflow.
11039 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11227 Use an inline function on all platforms when using the union type,

11314 * xdisp.c (vmessage): Treat frame message as multibyte.
11315 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
11316 would generate the diagnostic "Making \302\247 buffer-local while

11321 * dispnew.c (showing_window_margins_p): Undo last change, which
11322 was done due to an inadvertent commit.

11335 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11337 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11339 * alloc.c (allocate_vectorlike): Fix last change.

11343 Block-based vector allocation of small vectors.
11344 * lisp.h (struct vectorlike_header): New field `nbytes',
11345 adjust comment accordingly.
11346 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11347 to denote vector blocks. Adjust users (live_vector_p,
11348 mark_maybe_pointer, valid_lisp_object_p) accordingly.

11364 (init_alloc_once): Add call to init_vectors.
11366 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11368 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11370 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11372 * doprnt.c (doprnt): Truncate multibyte char correctly.
11373 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11374 would mishandle a string argument "Xc" if X was a multibyte
11375 character of length 2: it would truncate after X's first byte
11376 rather than including all of X.
11378 2012-06-06 Chong Yidong <cyd@gnu.org>
11380 * buffer.c (word_wrap): Doc fix.
11382 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11394 binary via PaX flags if the paxctl utility is available.
11395 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11396 Restore PaX flags to their default. (Bug#11398)
11398 2012-06-03 Chong Yidong <cyd@gnu.org>
11400 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11401 buffer (Bug#11226).

11408 position is past the end of the mode line string.
11410 * buffer.c (buffer_local_value_1): New function, split from
11411 Fbuffer_local_value; can return Qunbound.
11412 (Fbuffer_local_value): Use it.
11413 (Vmode_line_format): Docstring tweaks.
11415 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

11427 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11429 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11430 Convert pctcpu and pctmem to Lisp float properly.
11431 Let the compiler fold better, as 100.0/0x8000 is exact.
11433 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11435 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11438 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11442 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11444 For a 'struct window', replace some Lisp_Object fields to
11445 bitfields where appropriate, remove unused fields.
11446 * window.h (struct window): Remove unused 'last_mark_x' and
11447 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11448 change its type from Lisp_Object to bitfield.
11449 Change type of 'force_start', 'optional_new_start',
11450 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11451 fields from Lisp_Object to bitfield. Adjust users accordingly.
11453 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11455 Pacify gcc -Wdouble-precision when using Xaw.
11456 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11457 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11458 Use 'float' consistently, rather than 'float' in most places
11459 and 'double' in a couple of places.
11461 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11463 * xdisp.c (handle_stop): Detect whether we have overlay strings
11464 loaded by testing it->current.overlay_string_index to be
11465 non-negative, instead of checking whether n_overlay_strings is
11466 positive. (Bug#11587)
11468 2012-05-31 Chong Yidong <cyd@gnu.org>
11470 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11474 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11476 * search.c (search_buffer): Remove calls to
11477 r_alloc_inhibit_buffer_relocation, as it is now called by
11478 maybe_unify_char, which was the cause of relocation of buffer text
11481 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11483 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11484 for the duration of call to load_charset, to avoid problems with
11485 callers of maybe_unify_char that access buffer text through C
11488 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11489 decrement the inhibition flag, instead of just setting or
11492 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11494 Remove obsolete '#define static' cruft.
11495 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11496 This #undef was "temporary" in 2000; it is no longer needed
11497 now that '#define static' has gone away.
11498 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11499 (gray_bitmap_bits): Remove; no longer needed.
11500 All uses replaced with definiens.
11501 * xterm.c: Include "bitmaps/gray.xbm".
11503 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

11506 The following changes affect the code only when profiling.
11507 * dispnew.c (__executable_start): Rename from safe_bcopy.
11508 Define only on platforms that need it.
11509 * emacs.c: Include <sys/gmon.h> when profiling.
11510 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11511 (__executable_start): Remove decl, since lisp.h does it now.
11512 (safe_bcopy): Remove decl; no longer has that name.
11513 (main): Coalesce #if into single bit of code, for simplicity.
11514 Cast pointers to uintptr_t, since standard libraries want integers
11516 * lisp.h (__executable_start): New decl.
11518 2012-05-31 Glenn Morris <rgm@gnu.org>
11520 * image.c (Fimagemagick_types): Doc fix.

11541 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11543 Do not create empty overlays with the evaporate property (Bug#9642).
11544 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11545 Bug#9642, but explicitly check that the buffer the overlay would
11546 be moved to is live and rearrange lines to make sure that errors
11547 will not put the overlay in an inconsistent state.
11548 (Fdelete_overlay): Cosmetics.
11550 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11552 * w32term.c (my_bring_window_to_top): New function.
11553 (x_raise_frame): Use handle returned by DeferWindowPos, which
11554 could be different from the original one.
11555 Call my_bring_window_to_top instead of my_set_foreground_window.

11564 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11566 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11567 This avoids undefined behavior that might cause the eassert
11568 to not catch an out-of-range value.
11570 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11572 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11573 Update dependencies.
11575 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11577 * bidi.c (bidi_mirror_char): Fix last change.
11579 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11584 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11586 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11587 Only r_alloc_inhibit_buffer_relocation needed to be added;
11588 the others were already declared.
11590 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11591 before checking whether it's out of range. Put the check inside
11593 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11595 2012-05-27 Ken Brown <kbrown@cornell.edu>
11597 * callproc.c (Fcall_process): Restore a line that was accidentally
11598 commented out in the 2011-02-13 change (bug#11547).
11600 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11602 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11603 defined on ralloc.c.
11605 * buffer.c [REL_ALLOC]: Remove prototypes of
11606 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11607 they are now on lisp.h.
11609 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11611 * search.c (search_buffer): Use it to inhibit relocation of buffer
11612 text while re_search_2 is doing its job, because re_search_2 is
11613 passed C pointers to buffer text. (Bug#11519)
11615 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11616 Update value to 24.
11618 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11619 state after an additional call to move_it_in_display_line_to, keep
11620 the values of it->max_ascent and it->max_descent found for the
11622 (pos_visible_p): Revert the comparison against bottom_y to what it
11623 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11626 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11628 Fix coding-related core dumps with gcc -ftrapv.
11629 The code was computing A - B, where A and B are pointers, and B is
11630 random garbage. This can lead to core dumps on platforms that
11631 have special pointer registers, and it also leads to core dumps on
11632 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11633 A - B only when B is initialized properly.
11634 * coding.c (coding_set_source, coding_set_destination): Return void.
11635 (coding_change_source, coding_change_destinations): New functions,
11636 with the old behaviors of coding_set_source and coding_set_destination.
11637 All callers that need an offset changed to use these new functions.
11639 2012-05-26 Glenn Morris <rgm@gnu.org>
11641 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

11647 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11649 * w32console.c: Include window.h.
11650 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11652 (initialize_w32_display): Initialize mouse-highlight data.
11654 * w32inevt.c: Include termchar.h and window.h.
11655 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11656 moves, call note_mouse_highlight. If help_echo changed, call
11657 gen_help_event to produce help-echo message in the echo area.
11658 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11661 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11663 * lread.c (read1): Simplify slightly to avoid an overflow warning
11664 with GCC 4.7.0 on x86-64.
11666 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11668 * bidi.c (bidi_mirror_char): Revert last change: an int is
11669 definitely wide enough here.
11671 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

11681 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11683 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11685 Use int, not EMACS_INT, where int is wide enough.
11686 (inhibit_garbage_collection, Fgarbage_collect):
11687 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11688 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11689 int might not be wide enough.
11690 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11691 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11692 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11693 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11694 (bidi_level_of_next_char, bidi_move_to_visually_next):
11695 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11696 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11697 (Fkill_buffer, Fset_buffer_major_mode)
11698 (advance_to_char_boundary, Fbuffer_swap_text)

11700 (overlay_touches_p, struct sortvec, record_overlay_string)
11701 (overlay_strings, recenter_overlay_lists)

11705 (Foverlay_recenter, last_overlay_modification_hooks_used)
11706 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11707 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11708 (validate_region): Omit unnecessary test for b <= e,
11709 since that's guaranteed by the previous test.
11710 (adjust_overlays_for_delete): Avoid pos + length overflow.
11711 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11712 (report_overlay_modification):
11713 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11714 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11715 Omit pointer cast, which isn't needed anyway, and doesn't work
11716 after the EMACS_INT -> ptrdiff_t change.
11717 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11718 * buffer.h: Adjust decls to match defn changes elsewhere.
11719 (struct buffer_text, struct buffer):
11720 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11721 Use EMACS_INT, not int, where int might not be wide enough.
11722 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11723 not int, to avoid needless 32-bit limit on 64-bit hosts.
11724 (exec_byte_code): Use tighter memory-full test, one that checks
11725 for alloca overflow. Don't compute the address of the object just
11726 before an array, as that's not portable. Use EMACS_INT, not
11727 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11728 * callint.c (Fcall_interactively):
11729 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11730 * callproc.c (call_process_kill, Fcall_process):

11740 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11741 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11742 (casify_object): Avoid integer overflow when overallocating buffer.
11743 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11744 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

11746 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11747 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11748 integers are now checked earlier. All uses replaced with XINT.
11750 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11751 For CCL_MapSingle, check that content and value are in int range.
11752 (ccl_driver, Fregister_code_conversion_map):
11753 Check that Vcode_version_map_vector is a vector.
11754 (resolve_symbol_ccl_program): Check that vector header is in range.
11755 Always copy the vector, so that we can check its contents reliably
11756 now rather than having to recheck each instruction as it's being
11757 executed. Check that vector words fit in 'int'.
11758 (ccl_get_compiled_code, Fregister_ccl_program)
11759 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11760 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

11762 contents are in range.
11763 (Fccl_execute_on_string): Check that status is in range.

11765 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

11773 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11774 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11775 avoid mishandling large integers.

11786 Don't rely on undefined behavior with signed left shift overflow.
11787 Don't assume unsigned int fits into fixnum, or that fixnum fits
11788 into unsigned int. Don't require max_code to be a valid fixnum;
11789 that's not true for gb10830 4-byte on a 32-bit host. Allow
11790 invalid_code to be a cons, for the same reason. Require code_offset
11791 to be a character. Avoid int overflow if max_char is close
11793 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11794 this is intended anyway and avoids some undefined behavior.
11795 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11796 INDEX_TO_CODE_POINT, as that's what it expects.
11797 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11798 * charset.h (DECODE_CHAR): Return int, not unsigned;
11799 this is what was intended anyway, and it avoids undefined behavior.

11801 integer-overflow issues.
11802 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11803 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11804 where the argument is EMACS_INT, and this behavior is not intended.
11805 * chartab.c (Fmake_char_table, Fset_char_table_range)
11806 (uniprop_get_decoder, uniprop_get_encoder):
11807 Don't assume fixnum fits in int.
11808 * cmds.c (move_point): New function, that does the gist of
11809 Fforward_char and Fbackward_char, but does so while checking
11810 for integer overflow more accurately.
11811 (Fforward_char, Fbackward_char): Use it.
11812 (Fforward_line, Fend_of_line, internal_self_insert)

12416 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
12417 (handle_tool_bar_click):
12418 Use int, not unsigned, since we prefer signed and the signedness
12419 doesn't matter here.
12420 (get_next_display_element, next_element_from_display_vector):
12421 Use int, not EMACS_INT, when int is wide enough.
12422 (start_hourglass): Use duration_to_sec_usec to do proper
12423 overflow checking on durations.
12424 * xfaces.c (Fbitmap_spec_p):
12425 Check that fixnums are in proper range for system types.

12461 * xterm.c (x_x_to_emacs_modifiers):
12462 Don't assume EMACS_INT overflows nicely into int.
12463 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12464 may come from Lisp.
12465 (handle_one_xevent): NATNUMP can eval its arg twice.
12466 (x_connection_closed):
12467 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

12473 2012-05-25 Glenn Morris <rgm@gnu.org>
12475 * lisp.mk (lisp): Update for more files being compiled now.
12477 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12479 * lread.c: Remove `read_pure' which makes no difference.
12480 (read_pure): Remove var.
12481 (unreadpure): Remove function.
12482 (readevalloop): Don't call read_list with -1 flag.
12483 (read1, read_vector): Don't test read_pure any more.
12484 (read_list): Simplify.

12492 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12494 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12495 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12497 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12500 This directory predates autoconf and is no longer needed nowadays.
12501 Move its few remaining bits of functionality to where they're needed.
12502 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12503 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12504 * m/template.h: Remove.
12505 * Makefile.in (M_FILE): Remove. All uses removed.
12506 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12507 * lisp.h (USE_LSB_TAG):
12508 * mem-limits.h (EXCEEDS_LISP_PTR):
12509 Use VAL_MAX, not VALBITS, in #if.
12510 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12511 (EMACS_UINT): Define unconditionally now.
12512 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12513 (BITS_PER_EMACS_INT): New constants, replacing
12514 what used to be in config.h, but not useful in #if.
12515 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12516 define them any more.
12517 (VAL_MAX): New macro.
12519 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12520 BITS_PER_EMACS_INT, in #if.
12521 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12522 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12523 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12524 * s/ms-w32.h (DATA_START):
12525 Move here from removed file m/intel386.h.
12526 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12527 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12529 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12531 Assume C89 or later.
12532 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12533 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)

12552 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12554 2012-05-19 Ken Brown <kbrown@cornell.edu>
12556 * xfns.c (x_in_use): Remove `static' qualifier.
12557 * xterm.h (x_in_use): Declare.
12558 * xgselect.c: Include xterm.h.
12559 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12560 and `display_arg' (bug#9754).
12562 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12564 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12566 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12567 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12569 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12571 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12573 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12574 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12576 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12577 reference to image_cache->refcount.
12578 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12580 2012-05-17 Juri Linkov <juri@jurta.org>
12582 * search.c (Fword_search_regexp, Fword_search_backward)
12583 (Fword_search_forward, Fword_search_backward_lax)
12584 (Fword_search_forward_lax): Move functions to isearch.el
12585 (bug#10145, bug#11381).
12587 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12589 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12591 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12593 * lread.c (init_obarray): Declare Qt and Qnil as special.
12595 2012-05-14 Glenn Morris <rgm@gnu.org>
12597 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12598 Put "libexec" before "bin", for the sake of init_callproc_1.
12600 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12602 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12604 * unexaix.c: Port to more-recent AIX compilers.
12605 (report_error, report_error_1, make_hdr, copy_sym)
12606 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12607 Make arguments const char *, not char *, to avoid violations of C
12608 standard and to fix some AIX warnings reported by Gilles Pion.
12610 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12612 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12613 already have overlays loaded.
12614 (handle_single_display_spec): Before returning without displaying
12615 fringe bitmap, synchronize the bidi iterator with the main display
12616 iterator, by calling iterate_out_of_display_property.
12617 (iterate_out_of_display_property): Detect buffer iteration by
12618 testing that it->string is a Lisp string.
12619 (get_next_display_element): When the current object is exhausted,
12620 and there's something on it->stack, call set_iterator_to_next to
12621 proceed with what's on the stack, instead of returning zero.
12622 (set_iterator_to_next): If called at the end of a Lisp string,
12623 proceed to consider_string_end without incrementing string
12624 position. Don't increment display vector index past the end of
12625 the display vector. (Bug#11417)
12626 (pos_visible_p): Don't report a position visible when move_it_to
12627 stopped at the last line of window, which happens to be scanned
12628 backwards by the bidi iteration. (Bug#11464)
12630 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12632 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12633 and right-margin display specs even if the spec is invalid or we
12634 are on a TTY, and thus unable to display on the fringes.
12635 That's because the text with the property will not be displayed anyway,
12636 so we need to signal to the caller that this is a "replacing"
12637 display spec. This fixes display when the spec is invalid or we
12640 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12642 * unexaix.c (make_hdr): Fix typo in prototype.
12643 This bug broke the build on AIX. Problem reported by Gilles Pion.
12645 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12647 * keyboard.c (kbd_buffer_get_event): Read special events also in
12648 batch mode. (Bug#11415)
12650 2012-05-12 Glenn Morris <rgm@gnu.org>
12652 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12654 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12656 * lisp.mk (lisp): Add newcomment.elc.
12658 2012-05-12 Glenn Morris <rgm@gnu.org>
12660 * Makefile.in (MKDIR_P): New, set by configure.
12661 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12663 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12665 Remove unused function hourglass_started.
12666 * dispextern.h (hourglass_started):
12667 * w32fns.c (hourglass_started):
12668 * xdisp.c (hourglass_started): Remove.
12670 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12672 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12673 Update dependencies.
12675 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12677 * xgselect.c (xg_select): Put maxfds+1 into a var.
12678 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12680 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12682 2012-05-10 Dave Abrahams <dave@boostpro.com>
12684 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12685 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12687 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12689 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12690 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12691 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12692 Initialize xd_registered_buses.
12694 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12696 Untag more efficiently if USE_LSB_TAG.
12697 This is based on a proposal by YAMAMOTO Mitsuharu in
12698 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12699 For an admittedly artificial (nth 8000 longlist) benchmark on
12700 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12701 Emacs's overall text size by 1%.
12702 * lisp.h (XUNTAG): New macro.
12703 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12704 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12705 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12706 * eval.c (Fautoload):
12707 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12708 * frame.h (XFRAME): Use XUNTAG.
12710 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12711 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12712 Remove unportable assumptions about print widths of types like
12714 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12715 intptr_t when converting between pointer and integer, to avoid GCC
12716 warnings about wrong width.
12718 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12720 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12721 stack for each reader_thread, instead of defaulting to 8MB
12722 determined by the linker. This avoids failures in creating
12723 subprocesses on Windows 7, see the discussion in this thread:
12724 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12726 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12728 Fix up display of the *Minibuf-0* buffer in the mini window.
12729 * keyboard.c (read_char): Don't clear the echo area if there's no
12731 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12732 contents of *Minibuf-0*) if there's no message displayed in its stead.
12734 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12736 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12739 2012-05-06 Chong Yidong <cyd@gnu.org>
12741 * lisp.mk (lisp): Update.
12743 2012-05-05 Jim Meyering <meyering@redhat.com>
12745 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12747 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12749 * data.c (PUT_ERROR): New macro.
12750 (syms_of_data): Use it. Add new error type `user-error'.
12751 * undo.c (user_error): New function.
12752 (Fprimitive_undo): Use it.
12753 * print.c (print_error_message): Adjust print style for `user-error'.
12754 * keyboard.c (user_error): New function.
12755 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12757 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12759 Do not limit current-time-string to years 1000..9999.
12760 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12761 (Fcurrent_time_string): Support any year that is supported by the
12762 underlying localtime representation. Don't use asctime, as it
12763 has undefined behavior for years outside the range -999..9999.
12765 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12767 Fix race conditions involving setenv, gmtime, localtime, asctime.
12768 Without this fix, interrupts could mess up code that uses these
12769 nonreentrant functions, since setting TZ invalidates existing
12770 tm_zone or tzname values, and since most of these functions return
12771 pointers to static storage.
12772 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12773 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12774 Grow the critical sections to include not just invoking
12775 localtime/gmtime, but also accessing these functions' results
12776 including their tm_zone values if any, and any related TZ setting.
12777 (format_time_string): Last arg is now struct tm *, not struct tm **,
12778 so that the struct tm is saved in the critical section.
12779 All callers changed. Simplify allocation of initial buffer, partly
12780 motivated by the fact that memory allocation needs to be outside
12781 the critical section.
12783 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12785 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12786 with RESET_INTERVAL.
12788 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12789 Remove duplicated buffer name initialization.
12791 2012-05-02 Jim Meyering <jim@meyering.net>
12793 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12795 * xfns.c (x_window): Use xstrdup (Bug#11375).
12797 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12799 * xdisp.c (pos_visible_p): If already at a newline from the
12800 display string before the 'while' loop, don't walk back the glyphs
12801 from it3.glyph_row. Solves assertion violation when the display
12802 string begins with a newline (egg.el). (Bug#11367)
12804 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12806 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12809 2012-05-01 Glenn Morris <rgm@gnu.org>
12811 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12812 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12813 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12814 All were removed before 23.1.
12816 * dispnew.c: Remove HAVE_LIBNCURSES test;
12817 it is always true on relevant platforms.
12819 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12820 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

12832 Do not avoid creating empty evaporating overlays (Bug#9642).
12833 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12834 That is, do not delete an evaporating overlay if it becomes
12835 empty after its bounds are adjusted to fit within its buffer.
12836 This fix caused other problems, and I'm reverting it until we get
12837 to the bottom of them.
12839 2012-04-27 Chong Yidong <cyd@gnu.org>
12841 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12843 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12845 * xdisp.c (pos_visible_p): If the window start position is beyond
12846 ZV, start the display from buffer beginning. Prevents assertion
12847 violation in init_iterator when the minibuffer window is scrolled
12848 via the scroll bar.
12850 * window.c (window_scroll_pixel_based): Likewise.
12852 2012-04-27 Chong Yidong <cyd@gnu.org>

12859 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12861 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12863 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12864 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12866 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12868 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12869 display element, check also the underlying string or buffer
12870 character. (Bug#11341)
12872 * w32menu.c: Include w32heap.h.
12873 (add_menu_item): If the call to AppendMenuW (via
12874 unicode_append_menu) fails, disable Unicode menus only if we are
12875 running on Windows 9X/Me.
12877 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12879 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12880 (xgetint): Add missing shift for LSB tags.
12882 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12884 * keyboard.c (read_char): Don't wipe echo area for select window

12890 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12891 manipulation of :loaded-from data.
12893 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

12896 now a cons (bug#11311).
12898 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12900 Do not create empty overlays with the evaporate property (Bug#9642).
12901 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12902 if it becomes empty after its bounds are adjusted to fit within
12903 its buffer. Without this fix, in a nonempty buffer (let ((o
12904 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12905 yields an empty overlay that has the evaporate property, which is
12906 not supposed to happen.
12908 Fix minor GTK3 problems found by static checking.
12909 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12910 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)

12929 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12930 (__malloc_size_t, __malloc_ptrdiff_t):
12931 Remove. All uses removed, replaced by the definiens if needed,
12932 since we can assume C89 or better now.

12950 Omit no-longer-needed casts.
12951 (valloc): Use getpagesize, not __getpagesize.
12952 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

13021 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13023 * sysdep.c [__FreeBSD__]: Minor cleanups.
13024 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13025 Use Emacs indenting style more consistently. Avoid some casts.
13026 Use 'double' consistently rather than mixing 'float' and 'double'.
13028 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13030 * sysdep.c (list_system_processes, system_process_attributes):
13031 Add implementation for FreeBSD (Bug#5243).

13037 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13039 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13040 It is never used otherwise.
13042 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13044 * print.c (print_preprocess): Only check print_depth if print-circle
13046 (print_object): Check for cycles even when print-circle is nil and

13051 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13052 set the status to "failed" and ensure that sentinel is run.
13054 2012-04-20 Glenn Morris <rgm@gnu.org>
13056 * process.c (Fset_process_inherit_coding_system_flag)
13057 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13085 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13086 -Wunused-result, -Wunused-variable. This should go away once
13087 the Emacs and Gnulib regex code is merged.

13107 New extern decls, to avoid calling undeclared functions.
13108 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13109 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13110 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13111 (NEED_MEM_INSERT): New macro.
13112 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13113 Remove one incorrect comment and fix another.

13149 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13150 * s/netbsd.h, s/sol2-6.h:
13151 Remove definition of GC_MARK_STACK, since the default now works.
13152 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13155 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13157 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13159 * lread.c (lisp_file_lexically_bound_p):

13180 2012-04-11 Daniel Colascione <dancol@dancol.org>
13182 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13183 against is gone. It's better to use vfork now so that when Cygwin
13184 gains a new, working vfork, we use it automatically (bug#10398).
13186 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13206 * w32.c (w32_delayed_load): Record the full path of the library
13207 being loaded (bug#10424).
13209 2012-04-09 Glenn Morris <rgm@gnu.org>
13211 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13212 not just in the obarray, before snarfing them. (Bug#11036)

13220 * process.h: Add integer `gnutls_handshakes_tried' member to
13223 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
13224 Add convenience `GNUTLS_LOG2i' macro.
13226 * gnutls.c (gnutls_log_function2i): Convenience log function.
13227 (emacs_gnutls_read): Use new log functions,
13228 `gnutls_handshakes_tried' process member, and
13229 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13230 attempts per process (connection).
13232 2012-04-09 Chong Yidong <cyd@gnu.org>
13234 * eval.c (Fuser_variable_p, user_variable_p_eh)
13235 (lisp_indirect_variable): Functions deleted.
13236 (Fdefvar): Caller changed.
13238 * callint.c (Finteractive, Fcall_interactively):
13239 * minibuf.c (Fread_variable): Callers changed.
13241 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13243 * xdisp.c (set_cursor_from_row): If the display string appears in
13244 the buffer at position that is closer to point than the position
13245 after the display string, display the cursor on the first glyph of
13246 the display string. Fixes cursor display when a 'display' text
13247 property immediately follows invisible text. (Bug#11094)
13249 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13251 composite.c: use 'double' consistently
13252 * composite.c (get_composition_id): Use 'double' consistently
13253 instead of converting 'float' to 'double' and vice versa; this is
13254 easier to understand and avoids a GCC warning.

13281 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13282 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13283 objects, as mark_maybe_pointer will catch them otherwise.
13284 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13285 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13303 [!WINDOWSNT]: New macros.
13304 (init_libxml2_functions, libxml2_loaded_p): New functions.
13305 (parse_region): Call fn_xmlCheckVersion instead of using the macro

13307 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13308 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13310 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13311 Call init_libxml2_functions before calling libxml2 functions.
13312 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13314 * emacs.c: Don't include libxml/parser.h.
13315 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13316 xmlCleanupParser directly.
13318 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13320 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13322 * indent.c (Fvertical_motion): If there is a display string at
13323 point, use it.vpos to compute how many lines to backtrack after

13326 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13328 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13329 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13330 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13331 macros related to unification of CJK characters. For the details,
13332 see the discussion following the message here:
13333 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13335 2012-04-04 Chong Yidong <cyd@gnu.org>
13337 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13339 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13341 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13342 instead of alloca. (Bug#11138)
13344 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

13349 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13351 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13352 position we get to after a call to move_it_to fails the
13353 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13354 only if we wind up in a string from display property. (Bug#11063)
13356 * window.c (Fdelete_other_windows_internal): Invalidate the row
13357 and column information about mouse highlight, so that redisplay
13358 restores it after reallocating the glyph matrices. (Bug#7464)
13360 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13361 string comes from a `display' text property, use the buffer
13362 position of that property as if we actually saw that position in
13364 (move_it_by_lines): Remove the assertion that
13365 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13366 violated when there's a before-string at the beginning of a line.
13369 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13371 * xdisp.c (append_space_for_newline): If the default face was
13372 remapped, use the remapped face for the appended newline.
13373 (extend_face_to_end_of_line): Use the remapped default face for
13374 extending the face to the end of the line.
13375 (display_line): Call extend_face_to_end_of_line when the default
13376 face was remapped. (Bug#11068)
13378 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13380 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

13404 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13406 2012-03-25 Kenichi Handa <handa@m17n.org>
13408 * dispextern.h (struct glyph): Change the bit length of
13409 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13411 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13413 * s/ms-w32.h (tzname): Include time.h before redirecting to
13414 _tzname. Fixes the MSVC build. (Bug#9960)
13416 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13418 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13421 * xterm.c (XTread_socket): Only modify handling_signal if
13422 !SYNC_INPUT. (Bug#11080)
13424 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13426 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13427 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13428 when fetching a multibyte character consumes more bytes than
13429 CHAR_BYTES returns, due to unification of CJK characters in
13430 string_char. (Bug#11073)
13432 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13434 * process.c (wait_reading_process_output): Handle pty disconnect
13435 by refraining from sending oneself a SIGCHLD (bug#10933).

13443 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13444 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.

13459 to reflect default non-nil value of redisplay-dont-pause.
13461 2012-03-19 Kenichi Handa <handa@m17n.org>
13463 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13464 it fit in a valid range (Bug#11003).
13466 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13468 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13469 that is not from display property, accept the row as a "cursor
13470 row" if one of the string's character has a non-nil `cursor'
13471 property. Fixes cursor positioning when there are newlines in
13472 overlay strings, e.g. in icomplete.el. (Bug#11035)
13474 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13476 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13478 2012-03-12 Chong Yidong <cyd@gnu.org>
13480 * eval.c (inhibit_lisp_code): Rename from
13481 inhibit_window_configuration_change_hook; move from window.c.
13483 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13484 * window.c (run_window_configuration_change_hook)
13485 (syms_of_window): Callers changed.

13505 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13508 2012-03-03 Glenn Morris <rgm@gnu.org>
13510 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13512 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13514 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13515 position past the first glyph_row that ends at ZV. (Bug#10902)
13516 (redisplay_window, next_element_from_string): Fix typos in
13518 (redisplay_window): Pass to move_it_vertically the margin in
13519 pixels, not in screen lines.
13521 2012-03-02 Glenn Morris <rgm@gnu.org>
13523 * buffer.c (buffer-list-update-hook): Doc fix.
13525 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13527 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13528 push_it before setting up the iterator for the first overlay
13529 string, even if we have an empty string loaded.
13530 (next_overlay_string): If there's an empty string on the iterator
13531 stack, pop the stack. (Bug#10903)
13533 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13535 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13536 Suggested by Stefan Monnier in
13537 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13538 * alloc.c (widen_to_Lisp_Object): New static function.
13539 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13540 and widening them to Lisp_Objects. This would work even if
13541 USE_LSB_TAG is defined and wide integers are used, which might
13542 happen in a future version of Emacs.
13544 2012-02-25 Chong Yidong <cyd@gnu.org>
13546 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13549 * xselect.c (Fx_selection_exists_p): Doc fix.

13551 before saving to clipboard manager.
13553 2012-02-24 Chong Yidong <cyd@gnu.org>
13555 * keyboard.c (process_special_events): Handle all X selection
13556 requests in kbd_buffer, not just the next one (Bug#8869).
13558 2012-02-23 Chong Yidong <cyd@gnu.org>
13560 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13561 call when setting menu-bar-lines and tool-bar-lines parameters.
13562 (unwind_create_frame_1): New helper function.

13583 when computing $valmask.
13585 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13586 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13587 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13588 It's useless in that case, and it can cause problems on hosts
13589 that allocate halves of EMACS_INT values separately.
13590 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13591 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13592 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13593 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13594 it avoids undefined behavior on hosts where shifting right by more
13595 than the word width has undefined behavior.
13597 2012-02-19 Chong Yidong <cyd@gnu.org>
13599 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13600 (Funhandled_file_name_directory, Ffile_name_as_directory)

13619 2012-02-15 Chong Yidong <cyd@gnu.org>
13621 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

13637 2012-02-12 Chong Yidong <cyd@gnu.org>
13639 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13640 as that creates a dangerous corner case.
13642 * window.c (Fdelete_window_internal): Invalidate the mouse
13643 highlight (Bug#9904).
13645 2012-02-12 Glenn Morris <rgm@gnu.org>

13650 * nsselect.m (Fx_own_selection_internal)
13651 (Fx_disown_selection_internal, Fx_selection_exists_p)
13652 (Fx_selection_owner_p, Fx_get_selection_internal):
13653 Sync docs and argument specs with the xselect.c versions.
13655 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13657 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

13677 * buffer.c (Fbuffer_local_variables)
13678 (buffer_lisp_local_variables): Handle unbound vars correctly;
13679 don't let Qunbound leak into Lisp.
13681 2012-02-07 Glenn Morris <rgm@gnu.org>
13683 * image.c (Fimagemagick_types): Doc fix.
13685 * image.c (imagemagick-render-type): Change it from a lisp object
13686 to an integer. Move the doc here from the lisp manual.

13715 * keyboard.c (adjust_point_for_property): Don't position point
13716 before BEGV. (Bug#10696)
13718 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13720 Handle overflow when computing char display width (Bug#9496).
13721 * character.c (char_width): Return EMACS_INT, not int.
13722 (char_width, c_string_width): Check for overflow when
13723 computing the width; this is possible now that individual
13724 characters can have unbounded width. Problem introduced
13725 by merge from Emacs 23 on 2012-01-19.
13727 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

14223 attributes are tested _before_ calling verify_row_hash, to protect
14224 against GCC re-ordering of the tests. (Bug#10164)
14226 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>

14260 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
14261 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
14262 this macro definition.
14264 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
14267 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

14289 * xdisp.c (redisplay_window): If cursor row is not fully visible
14290 after recentering, and scroll-conservatively is set to a large
14291 number, scroll window by a few more lines to make the cursor fully
14292 visible and out of scroll-margin. (Bug#10105)
14293 (start_display): Don't move to the next line if the display should
14294 start at a newline that is part of a display vector or an overlay
14295 string. (Bug#10119)
14297 2011-11-24 Juri Linkov <juri@jurta.org>

14372 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
14374 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14375 Otherwise, valgrind does not work on some platforms.
14376 Problem reported by Andreas Schwab in
14377 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14378 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14379 is set, removing the need for VIRT_ADDRESS_VARIES.
14380 (PURE_P): Use a more-efficient implementation that needs just one
14381 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14382 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14383 to 4 (xorl, subq, cmpq, setbe).
14384 * alloc.c (pure): Always extern now, since that's the
14385 VIRT_ADDR_VARIES behavior.
14386 (PURE_POINTER_P): Use a single comparison, not two, for
14387 consistency with the new puresize.h.
14388 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14389 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
14390 Remove VIRT_ADDR_VARIES no longer needed.

14395 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14396 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14397 behave as if the cursor position were at the window margin.
14399 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14400 and the cursor position is out of bounds, behave as if the cursor
14401 position were at the window margin. (Bug#10075)
14403 2011-11-18 Chong Yidong <cyd@gnu.org>
14405 * window.c (Fwindow_combination_limit): Make first argument
14406 non-optional, since it is meaningless for live windows like the

14420 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
14421 hash values of the two rows.
14422 (copy_row_except_pointers): Preserve the used[] arrays and the
14423 hash values of the two rows. (Bug#10035)
14424 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14426 * xdisp.c (row_hash): New function, body extracted from
14427 compute_line_metrics.
14428 (compute_line_metrics): Call row_hash, instead of computing the
14431 * dispnew.c (verify_row_hash): Call row_hash for computing the
14432 hash code of a row, instead of duplicating code from xdisp.c.
14434 * dispextern.h (row_hash): Add prototype.
14436 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14438 * frame.c (delete_frame): Don't delete the terminal when the last
14439 X frame is closed if emacs is built with GTK toolkit.

14460 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
14461 (Fset_window_nest): Rename to Fset_window_combination_limit.
14462 (Vwindow_nest): Rename to Vwindow_combination_limit.
14463 (recombine_windows, make_parent_window, make_window)
14464 (Fsplit_window_internal, saved_window)
14465 (Fset_window_configuration, save_window_save): Rename all
14466 occurrences of window_nest to window_combination_limit.
14468 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
14470 * image.c (imagemagick_load_image): Fix typo.
14472 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14474 * xdisp.c (display_line): Move the call to
14475 highlight_trailing_whitespace before the call to
14476 compute_line_metrics, since the latter needs to see the final
14477 faces of all the glyphs to compute ROW's hash value.
14478 Fixes assertion violations in row_equal_p. (Bug#10035)
14480 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14482 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14483 just return (bug#10044).
14485 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14487 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14488 with user-defined heap size. Bump the default size of the temacs
14489 heap to 27MB, to avoid memory warning when running temacs.
14490 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
14492 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14493 current_matrix and desired_matrix. (Bug#9990)
14494 (verify_row_hash) [XASSERTS]: New function.
14495 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
14496 that the hash value of glyph rows is correct.

14525 2011-11-11 Johan Bockgård <bojohan@gnu.org>
14527 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
14528 avoid a crash (bug#9496).
14530 2011-11-09 Chong Yidong <cyd@gnu.org>
14532 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

14539 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14541 Avoid some portability problems by eschewing 'extern inline' functions.
14542 The trivial performance wins aren't worth the portability hassles; see
14543 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14545 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14546 (window_box_width, window_box_left, window_box_left_offset)
14547 (window_box_right, window_box_right_offset): Undo previous change,
14548 by removing the "extern"s.
14549 * intervals.c (adjust_intervals_for_insertion)
14550 (adjust_intervals_for_deletion): Undo previous change,
14551 making these static again.
14552 (offset_intervals, temp_set_point_both, temp_set_point)
14553 (copy_intervals_to_string): No longer inline.
14554 * xdisp.c (window_text_bottom_y, window_box_width)

14585 (delete_all_subwindows): Rename to delete_all_child_windows.
14586 (Fdelete_other_windows_internal, Fset_window_configuration):
14587 Call delete_all_child_windows instead of delete_all_subwindows.

14591 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
14593 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14594 This is also needed for porting to any host where GC_MARK_STACK is
14595 not GC_MAKE_GCPROS_NOOPS.
14596 (which_symbols): Use it.
14598 2011-11-07 Kenichi Handa <handa@m17n.org>
14600 * coding.c (coding_set_destination): Check coding->src_pos only
14601 when coding->src_object is a buffer (bug#9910).

14607 process_coding to 0 (bug#9912).
14609 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14611 * xmenu.c (cleanup_widget_value_tree): New function.
14612 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14613 calling free_menubar_widget_value_tree directly (Bug#9830).
14615 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14617 Fix some portability problems with 'inline'.
14618 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14619 (window_box_width, window_box_left, window_box_left_offset)
14620 (window_box_right, window_box_right_offset): Declare extern.
14621 Otherwise, these inline functions do not conform to C99 and
14622 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14623 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14624 * intervals.c (adjust_intervals_for_insertion)
14625 (adjust_intervals_for_deletion): Now extern, because otherwise the
14626 extern inline functions 'offset_intervals' couldn't refer to it.
14627 (static_offset_intervals): Remove.
14628 (offset_intervals): Rewrite using the old contents of
14629 static_offset_intervals. The old version didn't conform to C99
14630 because an extern inline function contained a reference to an
14631 identifier with static linkage.
14633 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14635 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14652 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
14653 (Fwindow_vscroll): Doc fix.
14654 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14655 argument, since it makes no sense to pass a live window and for
14656 consistency with window-child.

14829 Not clear what it was for, and it causes various bugs. (Bug#9839)
14831 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14833 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

14853 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14855 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14856 <oslsachem@gmail.com> for helping to debug this.
14858 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

14864 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14866 (w32font_open_internal, compute_metrics):
14867 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14868 instead of calling the "wide" APIs directly.
14870 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14872 * w32.h (syms_of_w32font): Add prototype.
14874 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

14878 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14879 (Fmove_to_window_line): Doc fix.
14881 2011-10-27 Chong Yidong <cyd@gnu.org>
14883 * process.c (make_process): Set gnutls_state to NULL.
14885 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14886 non-NULL, regardless of GNUTLS_INITSTAGE.
14887 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

14914 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14916 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14918 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14920 * keyboard.c (test_undefined): New function (bug#9751).
14921 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14923 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14925 * sysdep.c (init_sys_modes): Fix the check for the controlling
14926 terminal (Bug#6649).
14928 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14930 * dispextern.h (struct bidi_it): New member next_en_type.
14932 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14933 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14934 current character, check also for next_en_type being WEAK_EN.
14935 (bidi_resolve_weak): Don't enter the expensive loop if the current
14936 position is before next_en_pos. Record the bidi type of the first
14937 non-ET, non-BN character we find, in addition to its position.
14938 (bidi_level_of_next_char): Invalidate next_en_type when
14939 next_en_pos is over-stepped.
14941 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14943 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14944 * editfns.c: Rewrite current-time-zone so that it invokes
14945 the equivalent of (format-time-string "%Z") to get the time zone name.
14946 This fixes a bug when the time zone name contains characters that
14947 need converting from the system time locale to Emacs internal format.
14948 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14949 that patch fixed format-time-string to do the conversion, but
14950 I forgot to fix current-time-zone.
14951 (format_time_string): New function, containing most of
14952 what Fformat_time_string used to contain.
14953 (Fformat_time_string): Rewrite in terms of format_time_string.
14954 This doesn't change this function's behavior.
14955 (current-time-zone): Rewrite to use format_time_string.
14956 This fixes the bug reported by Michael Schierl in
14957 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14958 Jason Rumney's 2007-06-07 change worked around this bug, but
14960 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14962 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14964 * xdisp.c (start_display): If the character at POS is displayed
14965 via a display vector, reset IT->current.dpvec_index to zero.
14966 (try_window_reusing_current_matrix): If a line ends in a display
14967 vector or the next line starts in a display vector, continue
14968 redrawing the window even though the character position of
14969 start_row was reached.
14972 2011-10-18 Chong Yidong <cyd@gnu.org>
14974 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14975 with nobreak-char-display too.
14977 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14979 Fix part 3 of bug#9771.
14980 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14981 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14982 non-neutral characters if the current character is a paragraph
14983 separator (a.k.a. Newline). This avoids running the same
14984 expensive loop twice, once when we consume the preceding newline
14985 and the other time when the line actually needs to be displayed.
14986 Avoid the loop when we see neutrals on the base embedding level
14987 following a character whose directionality is the same as the
14988 paragraph's. This avoids running the expensive loop when a line
14989 ends in a long sequence of neutrals, like control characters.
14990 Add assertion against STRONG_AL type. Slightly rearrange code
14991 that determines the type of a neutral given the first non-neutral
14993 (bidi_level_of_next_char): Set next_en_pos to zero when
14994 invalidating its info.
14996 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14998 * xdisp.c (push_display_prop): Determine whether to record string
14999 or buffer position by IT->string, not by IT->method. Allow
15000 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15001 (move_it_vertically_backward): Don't look for character position
15002 immediately after the newline when in a continuation line.
15005 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15007 * window.c (coordinates_in_window): Rewrite and delabelize
15008 vertical border check. (Bug#5357) (Bug#9618)
15010 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15012 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15013 errors in XSetWindowBorder (bug#9310).
15015 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15017 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15018 avoid crash when xmalloc overrun checking is enabled.
15020 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15022 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15023 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15024 cursor motion with <left> and <right> arrow keys.
15026 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15027 some callers set that themselves.
15029 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15031 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15032 display string and the previous row comes from the same string and
15033 is empty. (Bug#9739) (Bug#9738)
15035 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15037 * doc.c (get_doc_string): Encode file name (bug#9735).
15039 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15041 * bidi.c (bidi_level_of_next_char):
15042 * xdisp.c (get_visually_first_element): Remove old incorrect
15043 comments regarding the Unicode Line Separator character.
15045 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15047 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15049 * alloc.c (Fgc_status): Do not access beyond zombies array
15050 boundary if nzombies > MAX_ZOMBIES.
15051 * alloc.c (dump_zombies): Add missing format specifier.
15053 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15055 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15056 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15058 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15059 Some packages use them to denote characters with modifiers.
15061 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15063 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15064 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15065 matching a pp-number. Rename parameter var to var1.
15067 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15069 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15071 2011-10-08 Glenn Morris <rgm@gnu.org>
15073 * callint.c (Fcall_interactively): Give a more explicit error for the
15074 'c' case with a non-character input. (Bug#8479)
15076 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15078 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15080 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15081 lines that are hscrolled on the left.

15084 presence of header-line. (Bug#4426)
15086 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15088 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15089 Don't advertise functionality which we discourage or doesn't work.
15091 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15093 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15094 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15095 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15096 this makes Emacs dump core during garbage collection on rare
15097 occasions. sizeof is obviously inferior to offsetof here, so
15098 stick with offsetof.
15099 (GC_POINTER_ALIGNMENT): New macro.
15100 (mark_memory): Omit 3rd (offset) arg; caller changed.
15101 Don't assume EMACS_INT alignment is the same as pointer alignment.
15103 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15105 * keyboard.c (read_key_sequence_remapped): New var.
15106 (read_key_sequence): Compute remapping in the right buffer.
15107 (command_loop_1): Use read_key_sequence's remapping directly.
15109 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15111 * dired.c (file_name_completion): Don't expand file name.
15112 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15113 before checking file name handler.
15115 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15116 they've been requested explicitly (bug#9591).
15118 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15120 * keymap.c (Fsingle_key_description): Use make_specified_string
15121 instead of build_string to build string from push_key_description.
15124 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15126 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15127 This fixes a Y2038 bug on 64-bit hosts.
15128 * buffer.c (reset_buffer):
15129 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15130 (Fclear_buffer_auto_save_failure):
15131 Use 0, not -1, to represent an unset failure time, since time_t
15132 might not be signed.
15134 Remove dependency on glibc malloc internals.
15135 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15136 Move back here from lisp.h, but with their new implementations.
15137 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15138 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15139 * charset.c (charset_table_init): New static var.
15140 (syms_of_charset): Use it instead of xmalloc. This removes a
15141 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15142 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15143 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15144 Move back to alloc.c.
15145 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15146 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15148 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15150 * nsterm.m (windowDidResize): Call x_set_window_size only when
15151 ns_in_resize is true. Otherwise set pixelwidth/height and
15152 call change_frame_size (Bug#9628).
15154 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15156 Port --enable-checking=all to Fedora 14 x86-64.
15157 * charset.c (syms_of_charset): Also account for glibc malloc's
15158 internal overhead when calculating the initial malloc maximum.
15160 Port --enable-checking=all to Fedora 14 x86.
15161 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15163 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15164 (overrun_check_realloc, overrun_check_free):
15165 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15166 That way, xmalloc returns a properly-aligned pointer even if
15167 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15168 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15169 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15170 into account when calculating the initial malloc maximum.
15171 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15172 Move here from alloc.c, so that charset.c can use it too.
15173 Properly align; the old code wasn't right for common 32-bit hosts
15174 when configured with --enable-checking=all.
15175 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15176 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15178 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15180 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15183 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15185 * xdisp.c (compute_display_string_end): If there's no display
15186 string at CHARPOS, return -1.
15188 * bidi.c (bidi_fetch_char): When compute_display_string_end
15189 returns a negative value, treat the character as a normal
15190 character not covered by a display string. (Bug#9624)
15192 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15194 * lread.c (Fread_from_string): Fix typo in docstring.
15196 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15198 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15199 newline, reseat the iterator instead of bidi-iterating there one
15200 character at a time. (Bug#9610)
15201 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15202 TO_CHARPOS if the bidi iterator is at base embedding level.
15204 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15206 * lread.c (readevalloop): Use correct code for NBSP.
15207 (read1): Likewise. (Bug#9608)
15209 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15211 * dbusbind.c (Fdbus_register_signal): When service is not
15212 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15214 2011-09-25 Glenn Morris <rgm@gnu.org>
15216 * buffer.c (truncate-lines): Doc fix.
15218 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15220 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15221 (Fset_window_next_buffers): Doc fix.
15223 2011-09-24 Glenn Morris <rgm@gnu.org>
15225 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15227 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15229 Fix minor problems found by static checking.
15230 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15231 * indent.c (Fvertical_motion): Fix == vs = typo.
15233 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15235 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15236 Default value is now t. Doc fix.
15238 * indent.c (Fvertical_motion): Compute and apply the overshoot
15239 logic when moving up, not only when moving down. Fix the
15240 confusing name and values of the it_overshoot_expected variable;
15241 logic changes accordingly. (Bug#9254) (Bug#9549)
15243 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15244 CHARPOS is covered by a display string which includes newlines.
15245 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15246 is covered by a display string with embedded newlines.
15248 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15250 * dbusbind.c (Fdbus_register_signal): Add match rule to
15251 Vdbus_registered_objects_table. (Bug#9581)
15252 (Fdbus_register_method, Vdbus_registered_objects_table):
15255 2011-09-24 Jim Meyering <meyering@redhat.com>
15257 do not ignore write error for any output size
15258 The previous change was incomplete.
15259 While it makes emacs --batch detect the vast majority of stdout
15260 write failures, errors were still ignored whenever the output size is
15261 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15262 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15263 && echo FAIL: ignored write error
15264 FAIL: ignored write error
15265 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15266 && echo FAIL: ignored write error
15267 FAIL: ignored write error
15268 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15270 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15272 * emacs.c (Fkill_emacs): In noninteractive mode exit
15273 non-successfully if a write error occurred on stdout. (Bug#9574)
15275 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15277 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15280 * dispextern.h (struct it): Update the comment documenting what
15283 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15285 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15286 a display string, extend search for cursor position to end of row.
15287 (find_row_edges): If the row ends in a newline from a display
15288 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15289 Handle the case of a display string with multiple newlines.
15290 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15291 non-empty line. Fixes confusing cursor motion with arrow keys at
15292 the beginning of a line that starts with whitespace.
15294 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15296 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15299 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15301 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15302 boolean (Bug#9154).
15304 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15306 * xdisp.c (display_line): Record maximum and minimum buffer
15307 positions even if no glyphs were produced (e.g., by a zero-width
15308 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15309 buffer positions that will be removed from the glyph row because
15311 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15312 column is beyond frame width: don't subtract 1 "pixel" when
15313 computing width of the stretch.
15314 (reseat_at_next_visible_line_start): Undo the change made on
15315 2011-09-17 that saved paragraph information and restored it after
15316 the call to `reseat'. (Bug#9545)
15318 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15320 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15321 and turn window cursor on if cleared (Bug#9415).
15323 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15325 * search.c (boyer_moore): Take unibyte characters from pattern
15326 literally. (Bug#9458)
15328 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15330 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15332 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15334 Fix minor problem found by static checking.
15335 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15336 initialized, to pacify gcc -Wuninitialized.
15338 * fileio.c: Report proper errno when syscall falls.
15339 (Finsert_file_contents): Save and restore errno,
15340 so that report_file_error outputs the correct diagnostic.
15341 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15343 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15345 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15347 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15349 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15350 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15352 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15354 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15355 about the current paragraph and restore it after the call to reseat.
15357 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15358 (bidi_find_paragraph_start): Search back for paragraph beginning
15359 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15360 (bidi_move_to_visually_next): Only trigger paragraph-related
15361 computations when the last character is a newline or at EOB, not
15362 just any NEUTRAL_B. (Bug#9470)
15364 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15365 truncated lines if point is covered by a display string. (Bug#9524)
15367 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15369 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15370 (cons_to_x_long): New function.
15371 (lisp_data_to_selection_data): Use it. Correct the test for
15372 short-versus-long data; it was negated. Break out of vector
15373 loop, for efficiency, when a long datum is discovered.
15375 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15377 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15379 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15381 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15382 GCC PR/17406) by declaring this function with external scope.
15384 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15386 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15387 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15389 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15391 * editfns.c (Fformat): Correctly handle text properties on "%%".

15399 * xdisp.c (get_next_display_element)
15400 (fill_composite_glyph_string): Add comments about special meaning
15401 of TAB characters in a composition.
15403 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15405 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15406 This occurs when processing a multibyte format.
15407 Problem reported by Wolfgang Jenker.
15409 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15411 * xdisp.c (try_cursor_movement): Only check for exact match if
15412 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15414 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15416 Remove unused external symbols.
15417 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15418 * xdisp.c (calc_pixel_width_or_height): Now static.
15419 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15420 * indent.c (check_display_width):
15421 * w32term.c: Fix comment to match code.
15422 * xterm.c, xterm.h (x_catching_errors): Remove.
15424 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15426 * xselect.c: Use signed conversions more consistently (Bug#9498).
15427 (selection_data_to_lisp_data): Assume incoming selection data are
15428 signed integers, not unsigned. This is to be consistent with
15429 outgoing selection data, which was modified to use signed integers
15430 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15431 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15432 expects long, not unsigned long.
15434 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15436 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15437 computation of loop end. Reported by Johan Bockgård
15440 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15442 * frame.c (Fother_visible_frames_p): Function deleted.
15444 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15446 * indent.c (compute_motion): Process display vector front to back
15447 rather than the other way around. (Bug#2496)
15449 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15451 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15453 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15455 * minibuf.c (Fread_from_minibuffer): Doc fix.
15457 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15459 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15460 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15462 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15464 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15465 value for non-existent files.
15467 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15469 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15470 set its "size" to -1. This will set the modtime_size field of
15471 the corresponding buffer to -1, which is what
15472 verify-visited-file-modtime expects for files that do not exist.
15475 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15477 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15479 * lisp.h: ... from here. push_key_description is no longer
15480 defined in keyboard.c, so its declaration should not be in
15481 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15482 logically belongs with push_key_description.
15484 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15486 * buffer.h: Include <sys/types.h> instead of <time.h>.
15487 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15488 Problem reported by Herbert J. Skuhra.
15490 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15492 * xml.c (parse_region): Make the parsing work for
15493 non-comment-starting XML files again (bug#9144).
15495 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15497 * image.c (gif_load): Fix calculation of bottom and right corner.
15500 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15502 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15503 redisplay in small windows.
15505 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15507 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15509 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15511 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15512 Operate on live windows only.
15514 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15516 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15518 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15520 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15521 only under bidi iteration.
15523 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15525 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15527 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15529 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15530 Without this fix, the command to link temacs failed due to an
15531 undefined symbol __builtin_isnan. This is because
15532 /usr/include/iso/math_c99.h #defines isnan(x) to
15533 __builtin_isnan(x), but the bundled gcc, which identifies itself
15534 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15536 * floatfns.c (isnan): #undef, and then #define to a clone of
15538 (Fisnan): Always define, since it's always available now.
15539 (syms_of_floatfns): Always define isnan at the Lisp level.
15541 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15543 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15545 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15547 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15548 The previous code assumed that file offsets (off_t values) fit in
15549 EMACS_INT variables, which is not true on typical 32-bit hosts.
15550 The code messed up by falsely reporting buffer overflow in cases
15551 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15552 when "big" contains more than 2**29 bytes, even though this
15553 inserts just one byte and does not overflow the buffer.
15554 (Finsert_file_contents): Store file offsets as off_t
15555 values, not as EMACS_INT values. Check for overflow when
15556 converting between EMACS_INT and off_t. When checking for
15557 buffer overflow or for overlap, take the offsets into account.
15558 Don't use EMACS_INT for small values where int suffices.
15559 When checking for overlap, fix a typo: ZV was used where
15560 ZV_BYTE was intended.
15561 (Fwrite_region): Don't assume off_t fits into 'long'.
15562 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15564 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15566 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15568 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15570 sprintf-related integer and memory overflow issues (Bug#9412).
15572 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15573 (esprintf, exprintf, evxprintf): New functions.
15574 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15575 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15576 (modify_event_symbol): Do not assume that the length of
15577 name_alist_or_stem is safe to alloca and fits in int.
15578 (Fexecute_extended_command): Likewise for function name and binding.
15579 (Frecursion_depth): Wrap around reliably on integer overflow.
15580 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15581 since some callers pass EMACS_INT values.
15582 (Fsingle_key_description): Don't crash if symbol name contains more
15583 than MAX_ALLOCA bytes.
15584 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15585 (get_minibuffer): Arg is now EMACS_INT, not int.
15586 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15587 (esprintf, exprintf, evxprintf): New decls.
15588 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15590 * dbusbind.c (signature_cat): New function.
15591 (xd_signature, Fdbus_register_signal):
15592 Do not overrun buffer; instead, report string overflow.
15594 * dispnew.c (add_window_display_history): Don't overrun buffer.
15595 Truncate instead; this is OK since it's just a log.
15597 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15598 even if the time zone offset is outlandishly large.
15599 Don't mishandle offset == INT_MIN.
15601 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15602 when creating daemon; the previous buffer-overflow check was incorrect.
15604 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15605 which has the guts of the old verror function.
15607 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15608 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15610 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15611 (font_unparse_xlfd): Don't blindly alloca long strings.
15612 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15613 fits in int, when using sprintf. Use single snprintf to count
15614 length of string rather than counting it via multiple sprintfs;
15615 that's simpler and more reliable.
15616 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15617 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15618 sprintf, in case result does not fit in int.
15620 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15621 (fontset_from_font): Print it.
15623 * frame.c (tty_frame_count): Now printmax_t, not int.
15624 (make_terminal_frame, set_term_frame_name): Print it.
15625 (x_report_frame_params): In X, window IDs are unsigned long,
15626 not signed long, so print them as unsigned.
15627 (validate_x_resource_name): Check for implausibly long names,
15628 and don't assume name length fits in 'int'.
15629 (x_get_resource_string): Don't blindly alloca invocation name;
15630 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15633 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15634 (xg_check_special_colors, xg_set_geometry):
15635 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15637 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15638 Use esprintf, not sprintf, in case result does not fit in int.
15640 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15641 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15642 it as a large positive number.
15643 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15644 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15646 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15647 in case result does not fit in int.
15649 * print.c (float_to_string): Detect width overflow more reliably.
15650 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15651 buffer overrun. Don't assume list length fits in 'int'. Treat
15652 print length of 0 as 0, not as infinity; to be consistent with other
15653 uses of print length in this function. Don't overflow print length
15654 index. Don't assume hash table size fits in 'long', or that
15655 vectorlike size fits in 'unsigned long'.
15657 * process.c (make_process): Use printmax_t, not int, to format
15658 process-name gensyms.
15660 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15662 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15663 to avoid potential buffer overrun.
15665 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15666 if X resource line is longer than 512 bytes.
15668 * xfns.c (x_window): Make sprintf buffer a bit bigger
15669 to avoid potential buffer overrun.
15671 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15673 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15675 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15677 Integer overflow fixes for scrolling, etc.
15678 Without these, Emacs silently mishandles large integers sometimes.
15679 For example, "C-u 4294967297 M-x recenter" was treated as if
15680 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15682 * xdisp.c (try_window_id): Check Emacs fixnum range before
15683 converting to 'int'.
15685 * window.c (window_scroll_line_based, Frecenter):
15686 Check that an Emacs fixnum is in range before assigning it to 'int'.
15687 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15688 values converted from Emacs fixnums.
15689 (Frecenter): Don't wrap around a line count if it is out of 'int'
15690 range; instead, treat it as an extreme value.
15691 (Fset_window_configuration, compare_window_configurations):
15692 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15694 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15695 that can exceed INT_MAX. Check that EMACS_INT value is in range
15696 before assigning it to the (possibly-narrower) index.
15697 (match_limit): Don't assume that a fixnum can fit in 'int'.
15699 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15702 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15703 (Fvertical_motion): Don't wrap around LINES values that don't fit
15704 in 'int'. Instead, treat them as extreme values. This is good
15705 enough for windows, which can't have more than INT_MAX lines anyway.
15707 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15709 * Require libxml/parser.h to avoid compilation warning.
15711 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15713 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15714 since this reportedly can destroy thread storage.
15716 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15718 * syntax.c (find_defun_start): Update all cache variables if
15719 exiting early (Bug#9401).
15721 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15723 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15725 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15726 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15727 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15729 * term.c (tty_append_glyph): New function.
15730 (produce_stretch_glyph): Static function and its prototype deleted.
15732 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15735 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15737 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15738 when checking :margin (Bug#9390).
15739 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15740 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15741 so that the name doesn't mislead. All uses changed.
15743 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15745 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15748 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15750 * xdisp.c (move_it_to): Don't bail out early when reaching
15751 position beyond to_charpos, if we are scanning backwards.
15752 (move_it_vertically_backward): When DY == 0, make sure we get to
15753 the first character in the line after the newline.
15755 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15757 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15758 (ccl_driver): Do not generate an out-of-range pointer.
15759 (Fccl_execute_on_string): Remove unnecessary check for
15760 integer overflow, noted by Stefan Monnier in
15761 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15762 Remove a FIXME that didn't need fixing.
15763 Simplify the newly-introduced buffer reallocation code.
15765 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15767 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15769 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15771 Integer and memory overflow issues (Bug#9196).
15773 * doc.c (get_doc_string): Rework so that
15774 get_doc_string_buffer_size is the actual buffer size, rather than
15775 being 1 less than the actual buffer size; this makes xpalloc more
15778 * image.c (x_allocate_bitmap_record, cache_image):
15779 * xselect.c (Fx_register_dnd_atom):
15780 Simplify previous changes by using xpalloc.
15782 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15783 since either will do and ptrdiff_t is convenient with xpalloc.
15785 * charset.c (charset_table_size)
15786 (struct charset_sort_data.priority): Now ptrdiff_t.
15787 (charset_compare): Don't overflow if priorities differ greatly.
15788 (Fsort_charsets): Don't assume list length fits in int.
15789 Check for size-calculation overflow when allocating sort data.
15790 (syms_of_charset): Allocate an initial charset table that is
15791 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15793 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15795 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15796 The actual value is always <= INT_MAX, and leaving it unsigned made
15797 overflow checking harder.
15799 * dispextern.h (struct glyph_matrix.rows_allocated)
15800 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15801 with xpalloc. The values are still always <= INT_MAX.
15803 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15805 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15806 (SAFE_NALLOCA): New macro.
15808 * region-cache.c (struct boundary.pos, find_cache_boundary)
15809 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15810 (set_cache_region, invalidate_region_cache)
15811 (revalidate_region_cache, know_region_cache, region_cache_forward)
15812 (region_cache_backward, pp_cache):
15813 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15814 so that ptrdiff_t * can be passed to xpalloc.
15815 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15816 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15817 (pp_cache): Don't assume cache_len fits in int.
15818 * region-cache.h: Adjust extern decls to match.
15820 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15821 EMACS_INT, since either will do, for xpalloc.
15823 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15824 (xnmalloc, xnrealloc, xpalloc): New functions.
15826 * bidi.c (bidi_shelve_header_size): New constant.
15827 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15828 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15830 * bidi.c (bidi_cache_shrink):
15831 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15833 Don't update size of array until after memory allocation succeeds,
15834 because xmalloc/xrealloc may not return.
15835 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15836 now that we have proper integer overflow checking.
15837 (record_overlay_string, overlay_strings): Catch overflows when
15838 calculating size of overlay_str_buf.
15840 * callproc.c (Fcall_process): Check for size overflow when
15841 calculating size of args2.
15842 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15843 Normally we prefer signed values, but sticking with ptrdiff_t would
15844 require adding more-complicated checks.
15846 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15847 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15848 Redo buffer-overflow calculations to avoid integer overflow.
15849 Add a FIXME comment where memory seems to be over-allocated.
15851 * character.c (Fstring): Check for size-calculation overflow.
15853 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15854 unnecessary integer overflow. Check for size overflow.
15855 (encode_coding_object): Don't update size until xmalloc succeeds.
15857 * composite.c (get_composition_id): Check for overflow in glyph
15858 length calculations.
15860 Integer and memory overflow fixes for display code.
15861 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15862 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15863 (scrolling_window): Check for overflow in size calculations.
15864 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15865 Don't assume glyph table len fits in int.

15867 (row_table_size): Now ptrdiff_t, not int.
15868 (scrolling_window): Avoid overflow in size calculations.
15869 Don't update size until allocation succeeds.
15870 * fns.c (concat): Check for overflow in size calculations.
15871 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15872 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15873 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15875 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15876 (get_doc_string): Check for size calculation overflow.
15877 Don't update size until allocation succeeds.
15878 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15879 EMACS_INT, where ptrdiff_t will do.
15880 (Fsubstitute_command_keys): Check for string overflow.
15882 * editfns.c (set_time_zone_rule): Don't assume environment length
15884 (message_length): Now ptrdiff_t, not int.
15885 (Fmessage_box): Don't update size until allocation succeeds.
15886 Don't assume message length fits in int.
15887 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15889 * emacs.c (main): Do not reallocate argv, since there is a null at
15890 the end that can be overwritten, and this way there's no need to
15891 worry about size-calculation overflow.
15892 (sort_args): Check for size-calculation overflow.
15894 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15896 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15898 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15899 (x_set_scroll_bar_width, x_figure_window_size):
15900 Check for integer overflow.
15901 (x_set_alpha): Do not assume XINT fits in int.
15903 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15904 This is for the members text_lines, text_cols, total_lines, total_cols,
15905 where the system imposes an 'int' limit.
15907 * fringe.c (Fdefine_fringe_bitmap):
15908 Don't update size until alloc works.
15910 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15911 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15913 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15914 Check for size-calculation overflow.
15915 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15916 do, as we prefer signed integers.
15917 (id_to_widget.max_size, id_to_widget.used)
15918 (xg_store_widget_in_map, xg_remove_widget_from_map)
15919 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15920 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15921 Use and return ptrdiff_t, not int.
15922 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15923 * gtkutil.h: Change prototypes to match the above.
15925 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15926 are duplicate now that they've been promoted to lisp.h.
15927 (x_allocate_bitmap_record, x_alloc_image_color)
15928 (make_image_cache, cache_image, xpm_load):
15929 Don't update size until alloc is done.
15930 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

15938 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15939 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15940 Use ptrdiff_t, not int, to count maps.
15941 (read_char_minibuf_menu_prompt): Check for overflow in size
15942 calculations. Don't update size until allocation succeeds.
15943 Redo calculations to avoid overflow.
15944 * keyboard.h: Change prototypes to match the above.
15946 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15948 (current_minor_maps): Check for size calculation overflow.
15949 * keymap.h: Change prototypes to match the above.
15951 * lread.c (read1, init_obarray): Don't update size until alloc done.
15953 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15972 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15973 for command line length. Do not attempt to address one before the
15974 beginning of an array, as that's not portable.
15976 * term.c (max_frame_lines): Remove; unused.
15977 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15979 (encode_terminal_code, calculate_costs): Check for size
15980 calculation overflow.

15998 Use ptrdiff_t, not int, for sizes.
15999 (store_mode_line_noprop_char): Don't update size until alloc done.
16001 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
16002 Use ptrdiff_t, not int, for sizes.
16003 (Finternal_make_lisp_face, cache_face):
16004 Check for size calculation overflow.
16005 (cache_face): Treat size calculation overflows as if they were
16006 memory exhaustion (the usual treatment), rather than aborting.
16008 * xfns.c (x_encode_text, x_set_name_internal)
16009 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16010 sizes, since they can exceed INT_MAX in size. Check for size
16011 calculation overflow.
16013 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16014 (xg_select): Check for size calculation overflow.
16015 Don't update size until alloc done.
16017 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16018 as sprintf is limited to int lengths.
16020 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16021 (X_LONG_MIN): New macros.
16022 Use them to make the following changes clearer.
16023 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16024 This change doesn't affect the value now, but it may help remind
16025 future maintainers not to raise the value too much later.
16026 (SELECTION_QUANTUM): Remove, replacing with ...
16027 (selection_quantum): ... new function, which avoids overflow.
16029 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16030 assumption that selection length fits in 'int'.
16031 (x_reply_selection_request, x_handle_selection_request)
16032 (x_get_window_property, receive_incremental_selection)
16033 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16034 (lisp_data_to_selection_data, clean_local_selection_data):
16035 Use ptrdiff_t, not int, to record length of selection.
16036 (x_reply_selection_request, x_get_window_property)
16037 (receive_incremental_selection, x_property_data_to_lisp):
16038 Redo calculations to avoid overflow.
16039 (x_reply_selection_request): When sending hint, ceiling it at
16040 X_LONG_MAX rather than relying on wraparound overflow to send
16042 (x_get_window_property, receive_incremental_selection)
16043 (lisp_data_to_selection_data, x_property_data_to_lisp):
16044 Check for size-calculation overflow.
16045 (x_get_window_property, receive_incremental_selection)
16046 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16047 Don't store size until memory allocation succeeds.
16048 (x_get_window_property): Plug memory leak on memory exhaustion.
16049 Don't double-block input; malloc is safe here. Don't assume 2**34
16050 - 4 fits in unsigned long. Add an xassert to check
16051 XGetWindowProperty overflow. Be more careful about overflow
16052 calculations, and distinguish size from memory overflow better.
16053 (receive_incremental_selection): When tracing, don't assume
16054 unsigned int is less than INT_MAX.
16055 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16056 harmful) conversions of unsigned short to int.
16057 (lisp_data_to_selection_data): Don't assume that integers
16058 in the range -65535 through -1 fit in an X unsigned short.
16059 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16060 result parameters unless successful. Rely on cons_to_unsigned
16061 to report problems with elements; the old code wasn't right anyway.
16062 (x_check_property_data): Check for int overflow; we cannot use
16063 a wider type due to X limits.
16064 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16066 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16068 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16069 (x_term_init): Check for size calculation overflow.
16070 (x_color_cells): Don't store size until memory allocation succeeds.
16071 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16072 Don't assume alloca size is less than MAX_ALLOCA.
16073 (x_term_init): Don't assume length fits in int (sprintf is limited
16076 Use ptrdiff_t for composition IDs.
16077 * character.c (lisp_string_width):
16078 * composite.c (composition_table_size, n_compositions)
16079 (get_composition_id, composition_gstring_from_id):
16080 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):

16094 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
16095 * image.c (xpm_get_color_table_h):
16096 * lisp.h (hash_lookup, hash_put):
16097 * minibuf.c (Ftest_completion):
16098 Use ptrdiff_t for hash table indexes, not int (which is too
16099 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16100 32-bit --with-wide-int hosts).
16102 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16103 Add a FIXME comment about memory leaks.
16104 (syms_of_charset): Don't assume xmalloc returns.
16106 Don't assume that stated character widths fit in int.
16107 * character.c (Fchar_width, c_string_width, lisp_string_width):
16108 * character.h (CHAR_WIDTH):
16109 * indent.c (MULTIBYTE_BYTES_WIDTH):
16110 Use sanitize_char_width to avoid undefined and/or bad behavior
16111 with outlandish widths.
16112 * character.h (sanitize_tab_width): Rename from sanitize_width,
16113 now that we have two such functions. All uses changed.
16114 (sanitize_char_width): New inline function.
16116 Don't assume that tab-width fits in int.
16117 * character.h (sanitize_width): New inline function.
16118 (SANE_TAB_WIDTH): New macro.
16119 (ASCII_CHAR_WIDTH): Use it.
16120 * indent.c (sane_tab_width): Remove. All uses replaced by
16121 SANE_TAB_WIDTH (current_buffer).
16122 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
16124 * fileio.c: Integer overflow issues with file modes.
16125 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16127 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16128 Remove unreachable code.
16129 (read_hex, load_charset_map_from_file): Check for integer overflow.
16131 * xterm.c: Don't go over XClientMessageEvent limit.
16132 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16133 (x_send_scroll_bar_event): Likewise. Check that the size does not
16134 exceed limits imposed by XClientMessageEvent, as well as the usual
16135 ptrdiff_t and size_t limits.
16137 * keyboard.c: Overflow, signedness and related fixes.
16138 (make_lispy_movement): Use same integer type in forward decl
16139 that is used in the definition.
16140 (read_key_sequence, keyremap_step):
16141 Change bufsize argument back to int, undoing my 2011-03-30 change.
16142 We prefer signed types, and int is wide enough here.
16143 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16144 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16145 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16146 length, not size_t. Use ptrdiff_t for index, not int.
16147 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16148 possibility of integer overflow.
16150 Overflow, signedness and related fixes for images.
16152 * dispextern.h (struct it.stack[0].u.image.image_id)
16153 (struct_it.image_id, struct image.id, struct image_cache.size)
16154 (struct image_cache.used, struct image_cache.ref_count):

16160 * xdisp.c (calc_pixel_width_or_height):
16161 * xfns.c (image_cache_refcount):
16162 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16163 on typical 64-bit hosts.

16169 when the callers expect that.
16170 (image_ascent): Redo ascent calculation to avoid int overflow.
16171 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16172 (lookup_image): Remove unnecessary tests.
16173 (xbm_image_p): Locals are now of int, not EMACS_INT,
16174 since parse_image_check makes sure they fit into int.
16175 (png_load, gif_load, svg_load_image):
16176 Prefer int to unsigned where either will do.
16177 (tiff_handler): New function, combining the cores of the
16178 old tiff_error_handler and tiff_warning_handler.
16179 This function is rewritten to use vsnprintf and thereby avoid
16180 stack buffer overflows. It uses only the features of vsnprintf
16181 that are common to both POSIX and native Microsoft.
16182 (tiff_error_handler, tiff_warning_handler): Use it.
16183 (tiff_load, gif_load, imagemagick_load_image):
16184 Don't assume :index value fits in 'int'.
16185 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16186 (imagemagick_load_image): Check that crop parameters fit into
16187 the integer types that MagickCropImage accepts. Don't assume
16188 Vimagemagick_render_type has a nonnegative value. Don't assume
16189 size_t fits in 'long'.
16190 (gs_load): Use printmax_t to print the widest integers possible.
16191 Check for integer overflow when computing image height and width.
16193 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16195 * xdisp.c (redisplay_window): Don't force window start if point
16196 will be invisible in the resulting window. (Bug#9324)

16200 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16201 the display spec is of the form `(space ...)'.
16202 (handle_display_spec): Return the value returned by
16203 handle_single_display_spec, not just 1 or zero.
16204 (handle_single_display_spec): If the display spec is of the form
16205 `(space ...)', and specifies display in the text area, return 2
16207 (try_cursor_movement): Check for the need to scroll more
16208 accurately, and prefer exact match for point under bidi.
16209 Don't advance `row' beyond the last row of the window.
16211 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16212 into disp_prop; all users changed.
16214 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16215 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16216 for the text covered by the display property.
16218 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
16220 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

16226 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16227 buffers, return left-to-right.
16228 (set_cursor_from_row): Consider candidate row a win if its glyph
16229 represents a newline and point is on that newline. Fixes cursor
16230 positioning on the newline at EOL of R2L text within L2R
16231 paragraph, and vice versa.
16232 (try_cursor_movement): Check continued rows, in addition to
16233 continuation rows. Fixes unwarranted scroll when point enters a
16234 continued line of R2L text within an L2R paragraph, or vice versa.
16235 (cursor_row_p): Consider the case of point being equal to
16236 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16237 from the end of a short line to the beginning of a continued line
16238 of R2L text within L2R paragraph.
16239 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16240 composed characters.
16242 * bidi.c (bidi_check_type): Use xassert.

16251 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
16253 * nsfont.m (ns_otf_to_script): Fix typo.
16255 2011-08-22 Kenichi Handa <handa@m17n.org>
16257 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16258 extra slot even if the purpose is char-code-property-table.
16260 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16262 * xdisp.c (redisplay_window): When computing centering_position,
16263 account for the height of the header line. (Bug#8874)
16265 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16266 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16267 candidate is selected by the mouse, and that candidate has a
16268 composed character under the mouse.
16270 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16271 coordinates reported by pos-visible-in-window-p for a composed
16272 character in column zero.
16274 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16276 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16278 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16280 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16281 consider it a hit if to_charpos is anywhere in the range of the
16282 composed buffer positions.
16284 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16286 * image.c (gif_load): Don't assume that each subimage has the same
16287 dimensions as the base image. Handle disposal method that is
16288 "undefined" by the gif spec (Bug#9335).
16290 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16292 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
16293 (Fcondition_case): Document `debug' symbol in error handler.
16295 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16297 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16298 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16299 from an Org mode buffer to a Speedbar frame.
16301 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16302 a composition, take its buffer position from IT->cmp_it.charpos.
16303 Fixes cursor positioning at the beginning of a line that begins
16304 with a composed character.
16306 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16308 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16309 character bidirectional type, use STRONG_L instead. Fixes crashes
16310 in a buffer produced by `describe-categories'.
16312 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16313 members before the level stack, so they would be saved and
16314 restored when copying iterator state. Fixes incorrect reordering
16315 around TABs covered by display properties.
16317 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16319 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
16321 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
16323 * eval.c (internal_condition_case, internal_condition_case_1)
16324 (internal_condition_case_2, internal_condition_case_n):
16325 Remove unnecessary aborts (Bug#9081).
16327 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16329 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16330 has no `load' handler, try opening the file locally. (Bug#9311)
16332 2011-08-16 Ken Brown <kbrown@cornell.edu>
16334 * gmalloc.c: Expand comment.
16336 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16338 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16339 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16341 2011-08-16 Ken Brown <kbrown@cornell.edu>
16343 Fix memory allocation problems in Cygwin build (Bug#9273).
16345 * unexcw.c (__malloc_initialized): Declare external variable.
16346 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16348 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16350 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
16352 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16353 in the static heap.
16354 [CYGWIN] (special_realloc): New function.
16355 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

16371 * chartab.c: Improve commentary for the uniprop_table API.
16373 * bidi.c (bidi_paragraph_init): Support zero value of
16374 bidi_ignore_explicit_marks_for_paragraph_level.
16375 (bidi_initialize): Use uniprop_table instead of including
16376 biditype.h and bidimirror.h.
16378 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16379 coordinates of the iterator when restoring from ppos_it.
16382 2011-08-14 Kenichi Handa <handa@m17n.org>
16384 * process.c (create_process): Call setup_process_coding_systems
16385 after the pid of the process is set to -1 (Bug#8162).
16387 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16389 * xdisp.c (move_it_in_display_line_to): Don't invoke
16390 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16391 ppos_it. Fixes vertical cursor motion when line beginning is
16392 covered by an image. (Bug#9296)
16394 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16396 * nsterm.h (ns_run_ascript): Declare.
16397 (NSAPP_DATA2_RUNASSCRIPT): Define.
16399 * nsfns.m (as_script, as_result, as_status): New static variables.
16400 (ns_run_ascript): New function.
16401 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16402 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16403 the event loop. Get status from as_status (Bug#7276).
16405 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16406 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16407 the event loop (Bug#7276).
16409 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16411 * gnutls.c (QCgnutls_bootprop_priority)
16412 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16413 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16414 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16415 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16416 (QCgnutls_bootprop_verify_hostname_error)
16417 (QCgnutls_bootprop_callbacks_verify): Rename from
16418 Qgnutls_bootprop_..., all uses changed.
16420 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16423 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16425 * xfaces.c (Qframe_set_background_mode): Now static.
16426 * dispextern.h (Qframe_set_background_mode): Remove decl.
16428 * process.c (Fnetwork_interface_info): Declare local only if needed.
16430 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16432 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16433 (Fnetwork_interface_list): Allocate in increments of bytes instead
16434 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16435 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16437 (struct ifflag_def): notrailers is smart on OSX.
16438 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16439 Get hardware address with getifaddrs if available.
16441 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16443 * xdisp.c (iterate_out_of_display_property): xassert that
16444 IT->position is set to within IT->object's boundaries. Break from
16445 the loop as soon as EOB is reached; avoids infloops in redisplay
16446 when IT->position is set up wrongly due to some bug.
16447 Set IT->current to match the bidi iterator unconditionally.
16448 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16449 entry. Force push_it to save on the stack the current
16450 buffer/string position, to be restored by pop_it. Fix flags in
16451 the iterator structure wrt the object coming from a display
16452 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16453 properties. (Bug#9284)
16455 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16457 * fontset.c (fontset_get_font_group): Add proper type checks.
16460 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

16470 no-display-properties-and-no-overlays under bidi display.
16471 Set disp_pos in the bidi iterator to avoid searches for display
16472 properties and overlays.
16474 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16476 * editfns.c (Fset_time_zone_rule): Document relationship with the

16480 the font entity extracted from the cache (Bug#8109).
16482 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16484 * composite.c (autocmp_chars): Don't reset point. That is done by
16485 restore_point_unwind (Bug#5984).
16487 2011-08-07 Juri Linkov <juri@jurta.org>
16489 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16490 to show the arg `TIME' instead of `TIMEVAL'.
16492 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16494 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16495 display property strides EOL and includes a newline, as in
16496 longlines-mode. (Bug#9254)
16497 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16498 word-wrap under bidirectional display. (Bug#9224)
16500 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16501 is non-zero, even if the data buffer is NULL. Fixes a crash in
16502 vertical-motion with longlines-mode. (Bug#9254)
16504 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16506 * bidi.c <bidi_cache_total_alloc>: Now static.
16507 (bidi_initialize): Initialize bidi_cache_total_alloc.
16509 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16512 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16513 amount allocated this far in `bidi_cache_total_alloc'.
16514 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16515 non-zero, only free the data buffer without restoring the cache
16516 contents. All callers changed.
16518 * dispextern.h (bidi_unshelve_cache): Update prototype.
16520 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16521 (move_it_in_display_line, move_it_to)
16522 (move_it_vertically_backward, move_it_by_lines): Replace the call
16523 to xfree to an equivalent call to bidi_unshelve_cache.
16524 (move_it_in_display_line_to): Fix logic of returning
16525 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16527 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16529 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16530 came from a string character with a `cursor' property. (Bug#9229)
16532 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16534 * Makefile.in (LIB_PTHREAD): New variable.
16535 (LIBES): Add LIB_PTHREAD (Bug#9216).
16537 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16538 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16540 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16542 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16544 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16546 * xterm.c (x_find_topmost_parent): New function.
16547 (x_set_frame_alpha): Find topmost parent window with
16548 x_find_topmost_parent and set the property there also (bug#9181).
16549 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16551 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16553 * callproc.c (Fcall_process): Avoid vfork clobbering
16554 the local vars buffer, coding_systems, current_dir.
16556 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16558 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16560 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16562 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16563 so that it is not optimized away.
16565 * xdisp.c (compute_display_string_pos): Remove unused local.
16567 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16569 Fix slow cursor motion and scrolling in large buffers with
16570 selective display, like Org Mode buffers. (Bug#9218)
16572 * dispextern.h (struct bidi_it): New member disp_prop_p.
16574 * xdisp.c: Remove one-slot cache of display string positions.
16575 (compute_display_string_pos): Accept an additional argument
16576 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16577 for a display string or property. If found, set DISP_PROP_P
16580 * bidi.c (bidi_fetch_char): Accept an additional argument
16581 DISP_PROP_P, and pass it to compute_display_string_pos.
16582 Only handle text covered by a display string if DISP_PROP_P is returned
16583 non-zero. All callers of bidi_fetch_char changed.
16585 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16587 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16589 2010-12-03 Don March <don@ohspite.net>
16591 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16592 last character M-[char] is translated to ESC [char] (bug#7541).
16594 2011-08-02 Kenichi Handa <handa@m17n.org>
16596 * lisp.h (uniprop_table): Extern it.
16598 * chartab.c (uniprop_table): Make it non-static.
16600 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16602 * xdisp.c (forward_to_next_line_start): Accept additional argument
16603 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16605 (reseat_at_next_visible_line_start): Use the bidi iterator state
16606 returned by forward_to_next_line_start to restore the state of
16607 it->bidi_it after backing up to previous newline. (Bug#9212)
16609 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16611 * regex.c (re_comp): Protoize.
16612 (re_exec): Fix return type.
16613 (regexec): Fix type of `ret'. (Bug#9203)
16615 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16617 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16618 This is needed if max-image-size is a floating-point number.
16620 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16622 * print.c (print_object): Print empty symbol as ##.
16624 * lread.c (read1): Read ## as empty symbol.
16626 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16628 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16629 setting frame foreground color (Bug#9175).
16630 (x_set_background_color): Likewise.
16632 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16633 contents (Bug#9176).
16634 (EmacsTooltip -init): Remove bezels and add shadows to
16637 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16638 or scroll bar (Bug#8470).
16640 * nsfont.m (nsfont_open): Remove assignment to voffset and
16641 unnecessary vars hshink, expand, hd, full_height, min_height.
16642 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16644 * nsterm.h (nsfont_info): Remove voffset field.
16646 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16648 Implement strike-through and overline on NextStep (Bug#8863).
16650 * nsfont.m (nsfont_open): Use underline position provided by font,
16651 instead of hard-coded value of 2.
16652 (nsfont_draw): Call ns_draw_text_decoration instead.
16654 * nsterm.h: Add declaration for ns_draw_text_decoration.
16656 * nsterm.m (ns_draw_text_decoration): New function for drawing
16657 underline, overline, and strike-through.
16658 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16659 ns_draw_text_decoration. Change treatment of cursor drawing to
16660 accommodate underlining, etc.
16662 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16664 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16667 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16669 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16670 Without this fix, if a signal arrives just after memory fills up,
16671 'malloc' might be invoked reentrantly.
16673 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16674 In other words, assume that every image size is allowed, on non-X
16675 hosts. This assumption is probably wrong, but it lets Emacs compile.
16677 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16679 * regex.c (re_iswctype): Convert return values to boolean.
16681 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16683 * xdisp.c (compute_display_string_pos): Don't use cached display
16684 string position if the buffer had its restriction changed.
16687 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16689 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16691 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16693 Integer signedness and overflow and related fixes. (Bug#9079)
16695 * bidi.c: Integer size and overflow fixes.
16696 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16697 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16698 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16699 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16700 (bidi_find_other_level_edge):
16701 Use ptrdiff_t instead of EMACS_INT where either will do.
16702 This works better on 32-bit hosts configured --with-wide-int.
16703 (bidi_cache_ensure_space): Check for size-calculation overflow.
16704 Use % rather than repeated addition, for better worst-case speed.
16705 Don't set bidi_cache_size until after xrealloc returns, because it
16707 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16708 (bidi_cache_ensure_space): Also check that the bidi cache size
16709 does not exceed that of the largest Lisp string or buffer. See Eli
16710 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16712 * alloc.c (__malloc_size_t): Remove.
16713 All uses replaced by size_t. See Andreas Schwab's note
16714 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16716 * image.c: Improve checking for integer overflow.
16717 (check_image_size): Assume that f is nonnull, since
16718 it is always nonnull in practice. This is one less thing to
16719 worry about when checking for integer overflow later.
16720 (x_check_image_size): New function, which checks for integer
16721 overflow issues inside X.
16722 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16723 This removes the need for a memory_full check.
16724 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16725 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16726 (xbm_read_bitmap_data): Change locals back to 'int', since
16727 their values must fit in 'int'.
16728 (xpm_load_image, png_load, tiff_load):
16729 Invoke x_create_x_image_and_pixmap earlier,
16730 to avoid much needless work if the image is too large.
16731 (tiff_load): Treat overly large images as if
16732 x_create_x_image_and_pixmap failed, not as malloc failures.
16733 (gs_load): Use x_check_image_size.
16735 * gtkutil.c: Omit integer casts.
16736 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16737 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16739 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16741 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16742 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16743 would wrongly return t on a 64-bit host.
16745 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16746 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16747 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16748 and therefore cause GCC to emit a bogus diagnostic in some cases.
16750 * image.c: Integer signedness and overflow and related fixes.
16751 This is not an exhaustive set of fixes, but it's time to
16752 record what I've got.
16753 (lookup_pixel_color, check_image_size): Remove redundant decls.
16754 (check_image_size): Don't assume that arbitrary EMACS_INT values
16755 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16756 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16757 (tiff_load, imagemagick_load_image):
16758 Check for overflow in size calculations.
16759 (x_create_x_image_and_pixmap): Remove unnecessary test for
16760 xmalloc returning NULL; that can't happen.
16761 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16762 (xpm_color_bucket): Use better integer hashing function.
16763 (xpm_cache_color): Don't possibly over-allocate memory.
16764 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16765 (gif_memory_source):
16766 Use ptrdiff_t, not int or size_t, to record sizes.
16767 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16768 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16769 either works, as we prefer signed integers.
16770 (tiff_read_from_memory, tiff_write_from_memory):
16771 Return tsize_t, not size_t, since that's what the TIFF API wants.
16772 (tiff_read_from_memory): Don't fail simply because the read would
16773 go past EOF; instead, return a short read.
16774 (tiff_load): Omit no-longer-needed casts.
16775 (Fimagemagick_types): Don't assume size fits into 'int'.
16777 Improve hashing quality when configured --with-wide-int.
16778 * fns.c (hash_string): New function, taken from sxhash_string.
16779 Do not discard information about ASCII character case; this
16780 discarding is no longer needed.
16781 (sxhash-string): Use it. Change sig to match it. Caller changed.
16782 * lisp.h: Declare it.
16783 * lread.c (hash_string): Remove, since we now use fns.c's version.
16784 The fns.c version returns a wider integer if --with-wide-int is
16785 specified, so this should help the quality of the hashing a bit.
16787 * emacs.c: Integer overflow minor fix.
16788 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16789 Define only if GNU_LINUX.
16790 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16792 * dispnew.c: Integer signedness and overflow fixes.
16793 Remove unnecessary forward decls, that were a maintenance hassle.
16794 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16796 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16797 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16798 (prepare_desired_row, line_draw_cost):
16799 Use int, not unsigned, where either works.
16800 (save_current_matrix, restore_current_matrix):
16801 Use ptrdiff_t, not size_t, where either works.
16802 (init_display): Check for overflow more accurately, and without
16803 relying on undefined behavior.
16805 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16806 Remove, replacing with the new symbols in lisp.h. All uses changed.
16807 * fileio.c (make_temp_name):
16808 * filelock.c (lock_file_1, lock_file):
16809 * xdisp.c (message_dolog):
16810 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16811 Use pMd etc. instead.
16812 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16813 replacing the pWIDE etc. symbols removed from editfns.c.
16815 * keyboard.h (num_input_events): Now uintmax_t.
16816 This is (very slightly) less likely to mess up due to wraparound.
16819 * buffer.c: Integer signedness fixes.
16820 (alloc_buffer_text, enlarge_buffer_text):
16821 Use ptrdiff_t rather than size_t when either will do, as we prefer
16824 * alloc.c: Integer signedness and overflow fixes.
16825 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16826 (__malloc_size_t): Default to size_t, not to int.
16827 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16828 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16829 Prefer ptrdiff_t to size_t when either would do, as we prefer
16831 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16832 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16833 Now const. Initialize with values that are in range even if char
16835 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16836 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16837 These functions do the right thing with sizes > 2**32.
16838 (check_depth): Now ptrdiff_t, not int.
16839 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16840 Adjust to new way of storing sizes. Check for size overflow bugs
16842 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16843 slightly wrong anyway, as it missed one instance of
16844 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16845 (refill_memory_reserve): Omit needless cast to size_t.
16846 (mark_object_loop_halt): Mark as externally visible.
16848 * xselect.c: Integer signedness and overflow fixes.
16849 (Fx_register_dnd_atom, x_handle_dnd_message):
16850 Use ptrdiff_t, not size_t, since we prefer signed.
16851 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16852 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16853 x_dnd_atoms_size and x_dnd_atoms_length.
16855 * doprnt.c: Prefer signed to unsigned when either works.
16857 * doprnt.c (doprnt):
16859 * xdisp.c (vmessage):
16860 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16861 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16862 prefer signed arithmetic to avoid comparison confusion.
16863 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16864 but is a bit tricky.
16866 Assume freestanding C89 headers, string.h, stdlib.h.
16867 * data.c, doprnt.c, floatfns.c, print.c:
16868 Include float.h unconditionally.
16869 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16870 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16871 * regex.c: Likewise for stddef.h, string.h.
16872 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16873 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16874 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16875 (STDC_HEADERS): Remove obsolete defines.
16876 * sysdep.c: Include limits.h unconditionally.
16878 Assume support for memcmp, memcpy, memmove, memset.
16879 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16880 * regex.c (memcmp, memcpy):
16881 Remove; we assume C89 now.
16883 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16884 (__malloc_safe_bcopy): Remove; no longer needed.
16886 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16887 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16888 well either way, and we prefer signed to unsigned.
16890 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16892 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16893 closes the connection while we're reading (bug#9182).
16895 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16897 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16898 are specified (Bug#9168).
16900 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16902 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16903 Found by GCC static checking and --with-wide-int on a 32-bit host.
16905 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16907 * xdisp.c (compute_display_string_pos): Fix logic of caching
16908 previous display string position. Initialize cached_prev_pos to
16909 -1. Fixes slow-down at the beginning of a buffer.
16911 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16913 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16914 for attrs[LFACE_FONTSET_INDEX].
16916 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16918 * xml.c (parse_region): Remove unused local
16919 that was recently introduced.
16921 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16923 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16924 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16926 * xdisp.c (move_it_in_display_line_to): Record the best matching
16927 position for TO_CHARPOS while scanning the line, and restore it on
16928 exit if none of the characters scanned was an exact match.
16929 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16930 when exact match is impossible due to invisible text, and the
16931 lines are truncated.
16933 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16935 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16938 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16940 Fix a significant slow-down of cursor motion with C-n, C-p,
16941 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16942 auto-repeat under bidi redisplay in fontified buffers.
16943 * xdisp.c (compute_stop_pos_backwards): New function.
16944 (next_element_from_buffer): Call compute_stop_pos_backwards to
16945 find a suitable prev_stop when we find ourselves before
16947 (reseat): Don't look for prev_stop, as that could mean a very long
16949 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16950 <cached_disp_overlay_modiff>: Cache for last found display string
16952 (compute_display_string_pos): Return the cached position if asked
16953 about the same buffer in the same area of character positions, and
16954 the buffer wasn't changed since the time the display string
16955 position was cached.
16957 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16959 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16960 is an integer, which is important for empty lines. (Bug#9149)
16962 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16964 * frame.c (Fmodify_frame_parameters): In tty case, update the
16965 default face if necessary (Bug#4238).
16967 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16969 * editfns.c (Fstring_to_char): No need to explain what a character
16970 is in the docstring (Bug#6576).
16972 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16974 * xml.c (parse_region): Make sure we always return a tree.
16976 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16978 * xml.c (parse_region): If a document contains only comments,
16981 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16983 * xml.c (make_dom): Return comments, too.
16985 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16988 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16989 and the surrounding thread.
16990 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16991 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16992 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16994 * s/openbsd.h (BROKEN_SIGIO): Define.
16995 * unexelf.c (unexec) [__OpenBSD__]:
16996 Don't update the .mdebug section of the Alpha COFF symbol table.
16998 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17000 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17003 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17005 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17006 This fixes some race conditions on the permissions of any newly
17009 * alloc.c (valid_pointer_p): Use pipe, not open.
17010 This fixes some permissions issues when debugging.
17012 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17013 If fchown fails to set both uid and gid, try to set just gid,
17014 as that is sometimes allowed. Adjust the file's mode to eliminate
17015 setuid or setgid bits that are inappropriate if fchown fails.
17017 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17019 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

17025 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17027 * lread.c (read_integer): Unread even EOF character.
17028 (read1): Likewise. Properly record start position of symbol.

17031 symbol character follows.
17033 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17035 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17036 This works around a problem with the previous change to Fcopy_file.
17037 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17038 and without this change, GCC might complain about discarding
17039 fchown's return value.
17041 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17043 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17045 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17047 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17049 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17051 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17052 it's used from the C level.
17054 * process.c: Use the same condition for POLL_FOR_INPUT in both
17055 keyboard.c and process.c (bug#1858).
17057 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17059 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17060 (Fgnutls_boot): Use it.
17062 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17064 * doc.c (Fsubstitute_command_keys): Revert last change.
17066 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17068 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17069 quotes the next character, and doesn't affect other longer
17070 sequences (bug#8935).
17072 * lread.c (syms_of_lread): Clarify that is isn't only
17073 `eval-buffer' and `eval-defun' that's affected by
17074 `lexical-binding' (bug#8460).
17076 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17078 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17079 bidi redisplay when a line includes both an image and is truncated.
17081 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17083 Fix minor problems found by static checking.
17084 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17085 (elsz): Now a signed constant, not a size_t var. We prefer signed
17086 types to unsigned, to avoid integer comparison confusion. Without
17087 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17088 "cannot optimize loop, the loop counter may overflow", a symptom
17090 * indent.c (Fvertical_motion): Mark locals as initialized.
17091 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17093 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

17116 buffer position was specified. Initialize paragraph_embedding to
17118 (reseat_to_string): Initialize the bidi iterator.
17119 (display_string): If we need to ignore text properties of
17120 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17121 original value of -1 will not work with bidi.)
17122 (compute_display_string_pos): First arg is now struct
17123 `text_pos *'; all callers changed. Support display properties on
17125 (compute_display_string_end): Support display properties on Lisp
17127 (init_iterator, reseat_1, reseat_to_string): Initialize the
17128 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17129 when iterating on a string not from display properties).
17130 (compute_display_string_pos, compute_display_string_end):
17131 Fix calculation of the object to scan. Fixes an error when using
17133 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17134 base_level_stop; instead, set base_level_stop to BEGV.
17135 Fixes crashes in vertical-motion.
17136 (next_element_from_buffer): Improve commentary for when
17137 the iterator is before prev_stop.
17138 (init_iterator): Initialize bidi_p from the default value of
17139 bidi-display-reordering, not from buffer-local value. Use the
17140 buffer-local value only if initializing for buffer iteration.

17161 parts of next_element_from_buffer, next_element_from_string, and
17162 next_element_from_c_string.

17164 (display_menu_bar): Force left-to-right direction. Add a FIXME
17165 comment for making that be controlled by a user option.

17174 (get_overlay_strings_1, push_display_prop): Set up the bidi
17175 iterator for displaying display or overlay strings.
17176 (forward_to_next_line_start): Don't use the shortcut if
17178 (back_to_previous_visible_line_start): If handle_display_prop
17179 pushed the iterator stack, restore the internal state of the bidi
17180 iterator by calling bidi_pop_it same number of times.
17181 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17182 and we are bidi-iterating, don't decrement the iterator position;
17183 instead, set the first_elt flag in the bidi iterator, to produce
17185 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17186 (push_display_prop): xassert that we are iterating a buffer.
17187 (push_it, pop_it): Save and restore paragraph_embedding member.
17188 (handle_single_display_spec, next_overlay_string)
17189 (get_overlay_strings_1, reseat_1, reseat_to_string)
17190 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17191 correctly. Don't assume unibyte strings are not bidi-reordered.

17200 property. Fix a typo in popping stretch info. Add an assertion
17201 for verifying that the iterator position is in sync with the bidi
17203 (handle_single_display_spec, get_overlay_strings_1)

17228 displayed in margins. (Bug#8133) (Bug#8867)
17229 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
17231 (pos_visible_p): Support positions in bidi-reordered lines.
17232 Save and restore bidi cache.
17234 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

17257 changed to -1 and -2, respectively.
17258 (bidi_char_at_pos): New function.
17259 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

17345 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17347 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17348 The old code sometimes used this field without initializing it.
17350 * alloc.c (gc_sweep): Don't read past end of array.
17351 In theory, the old code could also have corrupted Emacs internals,
17352 though it'd be very unlikely.

17619 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17657 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17658 subseconds part to the entropy, as that's a bit more random.
17659 Prefer signed to unsigned, since the signedness doesn't matter and
17660 in general we prefer signed. When given a limit, use a
17661 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17662 latter isn't right if USE_2_TAGS_FOR_INTS.
17663 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17664 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17676 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17677 This is more efficient than Ffile_directory_p and avoids a minor race.

17681 * buffer.c (Foverlay_put): Say what the return value is
17684 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17688 error be more correct.
17690 * fns.c (Frequire): Remove the mention of the .gz files, since

17707 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17708 Also (re)move comments that are misplaced or no longer relevant.

17793 (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
17794 with value as argument.
17795 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
17796 g_settings_new (Bug#8967). Do not create gsettings_obj.

17804 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
17807 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
17809 * eval.c (struct backtrace): Simplify and port the data structure.
17810 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17811 signed bit field, as this assumption is not portable and it makes
17812 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17813 "char debug_on_exit : 1" as this is not portable either; instead,
17814 use the portable "unsigned int debug_on_exit : 1". Remove unused
17815 member evalargs. Remove obsolete comments about cc bombing out.
17817 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17885 (emacs_fixed_new): Set priv->f to argument.
17886 (emacs_fixed_get_preferred_width)
17887 (emacs_fixed_get_preferred_height): Use min_width/height from
17888 frames size_hint to set minimum and natural (Bug#8919).
17889 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17890 and use min_width/height from frames size_hint to set
17891 min_width/height (Bug#8919).

17911 Use gnulib's dup2 module instead of rolling our own.
17912 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17979 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17981 Integer and buffer overflow fixes (Bug#8873).
17983 * print.c (printchar, strout): Check for string overflow.
17984 (PRINTPREPARE, printchar, strout):
17985 Don't set size unless allocation succeeds.
17987 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17988 for sizes. Check for string overflow more accurately.
17989 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17991 * macros.c: Integer and buffer overflow fixes.
17992 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17993 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17997 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17999 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18001 * lread.c: Integer overflow fixes.
18002 (read_integer): Radix is now EMACS_INT, not int,
18003 to improve quality of diagnostics for out-of-range radices.
18004 Calculate buffer size correctly for out-of-range radices.
18005 (read1): Check for integer overflow in radices, and in
18006 read-circle numbers.
18007 (read_escape): Avoid int overflow.
18008 (Fload, openp, read_buffer_size, read1)
18009 (substitute_object_recurse, read_vector, read_list, map_obarray):
18010 Use ptrdiff_t, not int, for sizes.

18025 2011-06-22 Leo Liu <sdl.web@gmail.com>
18027 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18028 Move to minibuffer.el.
18030 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18032 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18033 The following patches are for when GLYPH_DEBUG && !XASSERT.
18034 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18035 * dispnew.c (flush_stdout):
18036 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18037 Mark as externally visible.
18038 * dispnew.c (check_window_matrix_pointers): Now static.
18039 * dispnew.c (window_to_frame_vpos):
18040 * xfns.c (unwind_create_frame):
18041 * xterm.c (x_check_font): Remove unused local.
18042 * scroll.c (CHECK_BOUNDS):
18043 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18044 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18045 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18046 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18047 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18049 (debug_method_add): Use va_list and vsprintf rather than relying
18050 on undefined behavior with wrong number of arguments.
18051 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18052 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18053 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18054 since we're not interested in debugging glyphs with old libraries.
18055 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18056 GCC 4.6.0's static checking.
18058 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18060 Integer overflow and signedness fixes (Bug#8873).

18070 (x_create_bitmap_from_xpm_data):
18071 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18072 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18074 * xfaces.c (load_pixmap):
18075 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18076 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18077 (.bitmaps_last, struct x_output.icon_bitmap):
18078 Use ptrdiff_t, not int, for bitmap indexes.
18079 (x_allocate_bitmap_record): Check for size overflow.
18080 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18082 Use ptrdiff_t, not int, for overlay counts.
18083 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18084 * editfns.c (overlays_around, get_pos_property):
18085 * textprop.c (get_char_property_and_overlay):
18086 * xdisp.c (next_overlay_change, note_mouse_highlight):
18087 * xfaces.c (face_at_buffer_position):
18088 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18089 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18090 (Fnext_overlay_change, Fprevious_overlay_change)
18091 (mouse_face_overlay_overlaps, Foverlays_in):
18092 Use ptrdiff_t, not int, for sizes.
18093 (overlays_at, overlays_in): Check for size-calculation overflow.
18095 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18097 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18098 (x_session_initialize): Do not assume string length fits in int.
18100 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18101 This is unlikely, but can occur if DPI is outlandish.
18103 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18104 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18106 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18107 * xrdb.c (magic_file_p, search_magic_path):
18108 Omit last arg SUFFIX; it was always 0. All callers changed.
18109 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18111 * xfont.c (xfont_match): Avoid need for strlen.
18113 * xfns.c: Don't assume strlen fits in int.
18114 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18116 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18117 not unsigned long, as we prefer signed integers. All callers changed.
18118 Detect integer overflow in repeat count.
18119 (message_dolog): Don't assume print length fits in 39 bytes.
18120 (display_mode_element): Don't assume strlen fits in int.
18122 * termcap.c: Don't assume sizes fit in int and never overflow.
18123 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18124 (gobble_line): Check for size-calculation overflow.
18126 * minibuf.c (Fread_buffer):
18127 * lread.c (intern, intern_c_string):
18128 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18129 Don't assume string length fits in int.

18139 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18141 * filelock.c: Fix some buffer overrun and integer overflow issues.
18142 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18143 Reformulate so as not to need the command string.
18144 Invoke gzip -cd rather than gunzip, as it's more portable.
18145 (lock_info_type, lock_file_1, lock_file):
18146 Don't assume pid_t and time_t fit in unsigned long.
18147 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18148 (current_lock_owner): Prefer signed type for sizes.
18149 Use memcpy, not strncpy, where memcpy is what is really wanted.
18150 Don't assume (via atoi) that time_t and pid_t fit in int.
18151 Check for time_t and/or pid_t out of range, e.g., via a network share.
18152 Don't alloca where an auto var works fine.
18154 * fileio.c: Fix some integer overflow issues.
18155 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18156 Don't assume string length fits in int.
18157 (directory_file_name): Don't assume string length fits in long.
18158 (make_temp_name): Don't assume pid fits in int, or that its print
18159 length is less than 20.
18161 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18163 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18165 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18167 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18168 We prefer signed integers, even for size calculations.
18170 * emacs.c: Don't assume string length fits in 'int'.
18171 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18172 (main): Don't invoke strlen when not needed.

18177 * callproc.c (getenv_internal_1, getenv_internal)
18178 (Fgetenv_internal):
18179 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18181 * lread.c (invalid_syntax): Omit length argument.
18182 All uses changed. This doesn't fix a bug, but it simplifies the
18183 code away from its former Hollerith-constant appearance, and it's
18184 one less 'int' to worry about when looking at integer-overflow issues.
18185 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18187 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18188 This didn't break anything, but it didn't help either.
18189 It's confusing to put a bogus integer in a place where the actual
18190 value does not matter.
18191 (LIST_END_P): Remove unused macro and its bogus comment.
18192 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18194 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18195 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18197 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18198 We prefer signed types, and the value cannot exceed the EMACS_INT
18199 range anyway (because otherwise the length would not be representable).
18200 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18201 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18202 This avoids a GCC warning when WIDE_EMACS_INT.
18204 * indent.c (sane_tab_width): New function.
18205 (current_column, scan_for_column, Findent_to, position_indentation)
18206 (compute_motion): Use it. This is just for clarity.
18207 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18209 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18211 * lisp.h (lint_assume): New macro.
18212 * composite.c (composition_gstring_put_cache):
18213 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18215 * editfns.c, insdel.c:
18216 Omit unnecessary forward decls, to simplify future changes.
18218 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18220 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18222 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18223 Use much-faster test for byte-length change.
18224 Don't assume string byte-length fits in 'int'.
18225 Check that character arg fits in 'int'.
18226 (mapcar1): Declare byte as byte, for clarity.
18228 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18230 * fns.c (concat): Catch string overflow earlier.
18231 Do not rely on integer wraparound.
18233 * dispextern.h (struct it.overlay_strings_charpos)
18234 (struct it.selective): Now EMACS_INT, not int.
18235 * xdisp.c (forward_to_next_line_start)
18236 (back_to_previous_visible_line_start)
18237 (reseat_at_next_visible_line_start, next_element_from_buffer):
18238 Don't arbitrarily truncate the value of 'selective' to int.
18240 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18242 * composite.c: Don't truncate sizes to 'int'.
18243 (composition_gstring_p, composition_reseat_it)
18244 (composition_adjust_point): Use EMACS_INT, not int.
18245 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18246 not EMACS_UINT, for indexes.
18248 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18250 * buffer.c: Include <verify.h>.
18251 (struct sortvec.priority, struct sortstr.priority):
18252 Now EMACS_INT, not int.
18253 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18254 (struct sortstr.size, record_overlay_string)
18255 (struct sortstrlist.size, struct sortlist.used):
18256 Don't truncate size to int.
18257 (record_overlay_string): Check for size-calculation overflow.
18258 (init_buffer_once): Check at compile-time, not run-time.
18260 2011-06-22 Jim Meyering <meyering@redhat.com>
18262 Don't leak an XBM-image-sized buffer
18263 * image.c (xbm_load): Free the image buffer after using it.
18265 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18268 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18269 that Sun C diagnosed.
18270 * fns.c (secure_hash): Fix pointer signedness issue.
18271 * intervals.c (static_offset_intervals): New function.
18272 (offset_intervals): Use it.
18274 2011-06-21 Leo Liu <sdl.web@gmail.com>
18277 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18280 * fns.c (secure_hash): Rename from crypto_hash_function and change
18281 the first arg to accept symbols.
18282 (Fsecure_hash): New primitive.
18283 (syms_of_fns): New symbols.
18285 2011-06-20 Deniz Dogan <deniz@dogan.se>
18287 * process.c (Fset_process_buffer): Clarify return value in
18290 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18292 * dispnew.c (add_window_display_history): Use BVAR.
18294 * xdisp.c (debug_method_add): Use BVAR.
18295 (check_window_end, dump_glyph_matrix, dump_glyph)
18296 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18298 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18301 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18302 check till after the cache is created in init_frame_faces.
18304 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18306 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18308 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18310 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18311 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18312 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18314 Improve buffer-overflow checking (Bug#8873).
18315 * fileio.c (Finsert_file_contents):
18316 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18317 Remove the old (too-loose) buffer overflow checks.
18318 They weren't needed, since make_gap checks for buffer overflow.
18319 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18320 The old code merely checked for Emacs fixnum overflow, and relied
18321 on undefined (wraparound) behavior. The new code avoids undefined
18322 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18324 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18325 Tune. Don't use wider integers than needed. Don't use alloca.
18326 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18328 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18330 * insdel.c, lisp.h (buffer_overflow): New function.
18331 (insert_from_buffer_1, replace_range, replace_range_2):
18332 * insdel.c (make_gap_larger):
18333 * editfns.c (Finsert_char):
18334 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18336 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18338 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18340 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18342 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18343 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18345 * fileio.c: Don't assume EMACS_INT fits in off_t.
18346 (emacs_lseek): New static function.
18347 (Finsert_file_contents, Fwrite_region): Use it.
18348 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18350 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18352 * fns.c: Don't overflow int when computing a list length.
18353 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18354 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18355 truncation on 64-bit hosts. Check for QUIT every
18356 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18357 faster and is responsive enough.
18358 (Flength): Report an error instead of overflowing an integer.
18359 (Fsafe_length): Return a float if the value is not representable
18360 as a fixnum. This shouldn't happen except in contrived situations.
18361 (Fnthcdr, Fsort): Don't assume list length fits in int.
18362 (Fcopy_sequence): Don't assume vector length fits in int.
18364 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18365 (header_size, word_size): New constants.
18366 (allocate_vectorlike): Don't check size overflow here.
18367 (allocate_vector): Check it here instead, since this is the only
18368 caller of allocate_vectorlike that could cause overflow.
18369 Check that the new vector's length is representable as a fixnum.
18371 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18372 The previous code was bogus. For example, next_almost_prime (32)
18373 returned 39, which is undesirable as it is a multiple of 3; and
18374 next_almost_prime (24) returned 25, which is a multiple of 5 so
18375 why was the code bothering to check for multiples of 7?
18377 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18379 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18381 Variadic C functions now count arguments with ptrdiff_t.
18382 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18383 Back then I didn't know that the Emacs coding style prefers signed int.
18384 Also, in the meantime I found a few more instances where arguments
18385 were being counted with int, which may truncate counts on 64-bit
18386 machines, or EMACS_INT, which may be unnecessarily wide.
18387 * lisp.h (struct Lisp_Subr.function.aMANY)
18388 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18389 Arg counts are now ptrdiff_t, not size_t.
18390 All variadic functions and their callers changed accordingly.
18391 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18392 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18393 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18394 * callint.c (Fcall_interactively): Check arg count for overflow,
18395 to avoid potential buffer overrun. Use signed char, not 'int',
18396 for 'varies' array, so that we needn't bother to check its size
18397 calculation for overflow.
18398 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18399 * eval.c (apply_lambda):
18400 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18401 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18402 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18404 * callint.c (Fcall_interactively): Don't use index var as event count.
18406 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18407 * mem-limits.h (SIZE): Remove; no longer used.
18409 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18411 Remove unnecessary casts.
18412 * xterm.c (x_term_init):
18413 * xfns.c (x_set_border_pixel):
18414 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18415 These aren't needed now that we assume ANSI C.
18417 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18418 It's more likely to cause problems (due to unsigned overflow)
18421 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18423 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18425 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18427 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18429 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18431 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18433 GLYPH_CODE_FACE returns EMACS_INT, not int.
18434 * dispextern.h (merge_faces):
18435 * xfaces.c (merge_faces):
18436 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18437 Don't assume EMACS_INT fits in int.
18439 * character.h (CHAR_VALID_P): Remove unused parameter.
18440 * fontset.c, lisp.h, xdisp.c: All uses changed.
18442 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18444 * fns.c (concat): Minor tuning based on overflow analysis.
18445 This doesn't fix any bugs. Use int to hold character, instead
18446 of constantly refetching from Emacs object. Use XFASTINT, not
18447 XINT, for value known to be a character. Don't bother comparing
18448 a single byte to 0400, as it's always less.
18450 * floatfns.c (Fexpt):
18451 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18453 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18456 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18458 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18459 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18460 incorrectly succeed when S was a string, because 4294967386 was
18461 truncated before it was used.
18463 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18464 Otherwise, an out-of-range integer could cause undefined behavior
18467 * composite.c: Use int, not EMACS_INT, for characters.
18468 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18469 EMACS_INT, for values that are known to be in character range.
18470 This doesn't fix any bugs but is the usual style inside Emacs and
18471 may generate better code on 32-bit machines.
18473 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18474 This is for reasons similar to the recent CHAR_STRING fix.
18475 * charset.c (Fencode_char): Check that character arg is actually
18476 a character. Pass an int to ENCODE_CHAR.
18477 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18478 wider than 'int', as a compile-time check to prevent future regressions
18481 * character.c (char_string): Remove unnecessary casts.
18483 Make sure a 64-bit char is never passed to CHAR_STRING.
18484 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18485 by silently ignoring the top 32 bits, allowing some values
18486 that were far too large to be valid characters.
18487 * character.h: Include <verify.h>.
18488 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18489 arguments are no wider than unsigned, as a compile-time check
18490 to prevent future regressions in this area.
18492 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18493 (Fsubst_char_in_region):
18495 * xdisp.c (decode_mode_spec_coding):
18496 Adjust to CHAR_STRING's new requirement.
18497 * editfns.c (Finsert_char, Fsubst_char_in_region):
18498 * fns.c (concat): Check that character args are actually
18499 characters. Without this test, these functions did the wrong
18500 thing with wildly out-of-range values on 64-bit hosts.
18502 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18503 These casts should not be needed on 32-bit hosts, either.
18504 * keyboard.c (read_char):
18505 * lread.c (Fload): Remove casts to unsigned.
18507 * lisp.h (UNSIGNED_CMP): New macro.
18508 This fixes comparison bugs on 64-bit hosts.
18509 (ASCII_CHAR_P): Use it.
18510 * casefiddle.c (casify_object):
18511 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18512 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18513 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18514 * dispextern.h (FACE_FROM_ID):
18515 * keyboard.c (read_char): Use UNSIGNED_CMP.
18517 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18518 not to EMACS_INT, to avoid GCC warning.
18520 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18522 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18523 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18524 isn't needed on 32-bit machines.
18526 * buffer.c (Fgenerate_new_buffer_name):
18527 Use EMACS_INT for count, not int.
18528 (advance_to_char_boundary): Return EMACS_INT, not int.
18530 * data.c (Qcompiled_function): Now static.
18532 * window.c (window_body_lines): Now static.
18534 * image.c (gif_load): Rename local to avoid shadowing.
18536 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18537 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18538 * alloc.c (make_save_value): Integer argument is now of type
18539 ptrdiff_t, not int.
18540 (mark_object): Use ptrdiff_t, not int.
18541 * lisp.h (pD): New macro.
18542 * print.c (print_object): Use it.
18544 * alloc.c: Use EMACS_INT, not int, to count objects.
18545 (total_conses, total_markers, total_symbols, total_vector_size)
18546 (total_free_conses, total_free_markers, total_free_symbols)
18547 (total_free_floats, total_floats, total_free_intervals)
18548 (total_intervals, total_strings, total_free_strings):
18549 Now EMACS_INT, not int. All uses changed.
18550 (Fgarbage_collect): Compute overall total using a double, so that
18551 integer overflow is less likely to be a problem. Check for overflow
18552 when converting back to an integer.
18553 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18554 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18555 These were 'int' variables that could overflow on 64-bit hosts;
18556 they were never used, so remove them instead of repairing them.
18557 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18558 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18559 Previously, this ceilinged at INT_MAX, but that doesn't work on
18561 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18563 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18564 (allocate_vectorlike): Check for ptrdiff_t overflow.
18565 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18566 when a (possibly-narrower) signed value would do just as well.
18567 We prefer using signed arithmetic, to avoid comparison confusion.
18569 * alloc.c: Catch some string size overflows that we were missing.
18570 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18571 for convenience in STRING_BYTES_MAX.
18572 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18573 The definition here is exact; the one in lisp.h was approximate.
18574 (allocate_string_data): Check for string overflow. This catches
18575 some instances we weren't catching before. Also, it catches
18576 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18577 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18578 and ptrdiff_t and EMACS_INT are both 64 bits.
18580 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18581 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18582 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18584 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18586 * alloc.c (Fmake_string): Check for out-of-range init.
18588 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18590 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18592 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18594 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18595 xg_get_default_scrollbar_width.
18597 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18598 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18599 (style_changed_cb): Call update_theme_scrollbar_width and call
18600 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18601 all frames (Bug#8505).
18602 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18603 Call gtk_window_set_resizable if HAVE_GTK3.
18604 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18605 and height if HAVE_GTK3 (Bug#8505).
18606 (scroll_bar_width_for_theme): New variable.
18607 (update_theme_scrollbar_width): New function.
18608 (xg_get_default_scrollbar_width): Move code to
18609 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18610 (xg_initialize): Call update_theme_scrollbar_width.
18612 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18614 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18616 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18618 * frame.c (make_frame): Call other_buffer_safely instead of
18621 * window.c (temp_output_buffer_show): Call display_buffer with
18622 second argument Vtemp_buffer_show_specifiers and reset latter
18623 immediately after the call.
18624 (Vtemp_buffer_show_specifiers): New variable.
18625 (auto_window_vscroll_p, next_screen_context_lines)
18626 (Vscroll_preserve_screen_position): Remove leading asterisks from
18629 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18631 Fix minor problems found by GCC 4.6.0 static checking.
18632 * buffer.c (Qclone_number): Remove for now, as it's unused.
18633 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18634 (record_buffer): Remove unused local.
18635 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18636 (set_frame_buffer_list): Remove; unused.
18637 * frame.h (other_visible_frames): Remove decl.
18638 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18639 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18640 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18642 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18643 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18644 Define only if HAVE_GPM.
18645 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18646 (update_hints_inhibit): Remove; never set. All uses removed.
18647 * widgetprv.h (emacsFrameClassRec): Remove decl.
18648 * window.c (delete_deletable_window): Now returns void, since it
18649 wasn't returning anything.
18650 (compare_window_configurations): Remove unused locals.
18651 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18652 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18653 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18654 the same widths as pointers. This follows up on the 2011-05-06 patch.
18655 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18656 * xterm.h: Likewise.
18657 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18659 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18661 * makefile.w32-in: Update dependencies.

19119 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
19120 New error handlers.
19121 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
19122 Obey Vx_select_enable_clipboard_manager. Catch errors in
19123 x_clipboard_manager_save (Bug#8779).
19124 (Vx_select_enable_clipboard_manager): New variable.
19125 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19127 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19129 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19131 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19133 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
19134 in the current matrix if keep_current_p is non-zero.
19136 2011-06-04 Eli Zaretskii <eliz@gnu.org>
19138 * bidi.c (bidi_level_of_next_char): Fix last change.
19140 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19142 Support bidi reordering of text covered by display properties.
19144 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19145 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19146 (bidi_cache_search, bidi_cache_iterator_state)
19147 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19148 (bidi_level_of_next_char, bidi_move_to_visually_next):
19149 Support character positions inside a run of characters covered by a
19151 (bidi_paragraph_init, bidi_resolve_explicit_1)
19152 (bidi_level_of_next_char): Call bidi_fetch_char and
19153 bidi_fetch_char_advance instead of FETCH_CHAR and
19154 FETCH_CHAR_ADVANCE.
19155 (bidi_init_it): Initialize new members.
19156 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19158 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19159 instead of using explicit *_CHAR codes.
19160 (bidi_resolve_explicit, bidi_resolve_weak):
19161 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19162 bidirectional text is supported only in multibyte buffers.
19163 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19164 it to initialize the frame_window_p member of struct bidi_it.
19165 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19166 (bidi_resolve_explicit, bidi_resolve_weak)
19167 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
19168 bidi_it->nchars is non-positive.
19169 (bidi_level_of_next_char): Don't try to lookup the cache for the
19170 next/previous character if nothing is cached there yet, or if we
19171 were just reseat()'ed to a new position.
19173 * xdisp.c (set_cursor_from_row): Set start and stop points
19174 according to the row's direction when priming the loop that looks
19175 for the glyph on which to display cursor.
19176 (single_display_spec_intangible_p): Function deleted.
19177 (display_prop_intangible_p): Reimplement to call
19178 handle_display_spec instead of single_display_spec_intangible_p.
19179 Accept 3 additional arguments needed by handle_display_spec.
19180 This fixes incorrect cursor motion across display property with complex
19181 values: lists, `(when COND...)' forms, etc.
19182 (single_display_spec_string_p): Support property values that are
19183 lists with the argument STRING its top-level element.
19184 (display_prop_string_p): Fix the condition for processing a
19185 property that is a list to be consistent with handle_display_spec.
19186 (handle_display_spec): New function, refactored from the
19187 last portion of handle_display_prop.
19188 (compute_display_string_pos): Accept additional argument
19189 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19190 value of a `display' property is a "replacing spec".
19191 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19192 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19193 the display property, but just return a value indicating whether
19194 the display property will replace the characters it covers.
19195 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19196 frame_window_p members of struct bidi_it.
19197 (compute_display_string_pos, compute_display_string_end):
19199 (push_it): Accept second argument POSITION, where pop_it should
19200 jump to continue iteration.
19201 (reseat_1): Initialize bidi_it.disp_pos.
19203 * keyboard.c (adjust_point_for_property): Adjust the call to
19204 display_prop_intangible_p to its new signature.
19206 * dispextern.h (struct bidi_it): New member frame_window_p.
19207 (bidi_init_it): Update prototypes.
19208 (display_prop_intangible_p): Update prototype.
19209 (compute_display_string_pos, compute_display_string_end):
19210 Declare prototypes.
19211 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19214 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19216 Malloc failure behavior now depends on size of allocation.
19217 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19218 * lisp.h: Change signatures accordingly.
19219 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19220 All callers changed. (Bug#8762)
19222 * gnutls.c: Use Emacs's memory allocators.
19223 Without this change, the gnutls library would invoke malloc etc.
19224 directly, which causes problems on non-SYNC_INPUT hosts, and which
19225 runs afoul of improving memory_full behavior. (Bug#8761)
19226 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19227 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19228 xfree instead of the default malloc, realloc, free.
19229 (Fgnutls_boot): No need to check for memory allocation failure,
19230 since xmalloc does that for us.
19232 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19233 * category.c (hash_get_category_set):
19234 * ccl.c (ccl_driver):
19235 * charset.c (Fdefine_charset_internal):
19236 * charset.h (struct charset.hash_index):
19237 * composite.c (get_composition_id, gstring_lookup_cache)
19238 (composition_gstring_put_cache):
19239 * composite.h (struct composition.hash_index):
19240 * dispextern.h (struct image.hash):
19241 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19242 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
19243 (hashfn_equal, hashfn_user_defined, make_hash_table)
19244 (maybe_resize_hash_table, hash_lookup, hash_put)
19245 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19246 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19247 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19248 * image.c (make_image, search_image_cache, lookup_image)
19249 (xpm_put_color_table_h):
19250 * lisp.h (struct Lisp_Hash_Table):
19251 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19252 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19253 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19254 * alloc.c (allocate_vectorlike):
19255 Check for overflow in vector size calculations.
19256 * ccl.c (ccl_driver):
19257 Check for overflow when converting EMACS_INT to int.
19258 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19259 need to be updated by these changes.
19260 * fns.c (make_hash_table, maybe_resize_hash_table):
19261 Check for integer overflow with large hash tables.
19262 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19263 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19264 (SXHASH_REDUCE): New macro.
19265 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19266 Use it instead of discarding useful hash info with large hash values.
19267 (sxhash_float): New function.
19268 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19269 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19270 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19271 Rewrite to use FIXNUM_BITS, as this simplifies things.
19272 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19273 Adjust signatures to match updated version of code.
19274 (consing_since_gc): Now EMACS_INT, since a single hash table can
19275 use more than INT_MAX bytes.
19277 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19279 Make it possible to build with GCC-4.6+ -O2 -flto.
19281 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19283 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19285 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19286 Call minibuffer-inactive-mode.
19288 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19290 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19291 Update dependencies.
19293 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19295 * data.c (init_data): Remove code for UTS, this system is not
19298 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19300 Don't force ./temacs to start in terminal mode.
19302 * frame.c (make_initial_frame): Initialize faces in all cases, not
19303 only when CANNOT_DUMP is defined.
19304 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19306 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19308 * dispnew.c (add_window_display_history): Use const for the string
19309 pointer. Remove declaration, not needed.
19311 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19313 Use 'inline', not 'INLINE'.
19314 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19315 * alloc.c, fontset.c (INLINE): Remove.
19316 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19317 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19318 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19319 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19320 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19322 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19324 Make it possible to run ./temacs.
19326 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19327 syms_of_callproc does the same thing. Remove test for
19328 "initialized", do it in the caller.
19329 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19331 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19333 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19334 (read_minibuf): Use get_minibuffer.
19335 (syms_of_minibuf): Use DEFSYM.
19336 (Qmetadata): New var.
19337 * data.c (Qbuffer): Don't make it static.
19338 (syms_of_data): Use DEFSYM.
19340 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19342 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19343 (CCL_CODE_MIN): New macro.
19345 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19347 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19349 * eval.c (Qdebug): Now static.
19350 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19351 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19352 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19354 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19356 * image.c: Various fixes to ImageMagick code comments.
19357 (Fimagemagick_types): Doc fix.
19359 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19361 Minor fixes prompted by GCC 4.6.0 warnings.
19363 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19365 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19366 (x_clipboard_manager_save_all): Move extern decl to ...
19367 * xterm.h: ... here, so that it can be checked for consistency.
19369 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19371 * xselect.c (x_clipboard_manager_save_frame)
19372 (x_clipboard_manager_save_all): New functions.
19373 (Fx_clipboard_manager_save): Lisp function deleted.
19375 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19376 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19378 * xterm.h: Update prototype.
19380 2011-05-28 William Xu <william.xwl@gmail.com>
19382 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19383 exiting (Bug#8239).
19385 2011-05-28 Jim Meyering <meyering@redhat.com>
19387 Avoid a sign-extension bug in crypto_hash_function.
19388 * fns.c (to_uchar): Define.
19389 (crypto_hash_function): Use it to convert some newly-signed
19390 variables to unsigned, to avoid sign-extension bugs. For example,
19391 without this change, (md5 "truc") would evaluate to
19392 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19393 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19394 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19396 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19398 Integer overflow fixes.
19400 * dbusbind.c: Serial number integer overflow fixes.
19401 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19402 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19403 to hold a serial number that is too large for a fixnum.
19404 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19405 Check for serial numbers out of range. Decode any serial number
19406 that was so large that it became a float. (Bug#8722)
19408 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19409 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19410 Use XFASTINT rather than XUINT when numbers are nonnegative.
19411 (xd_append_arg, Fdbus_method_return_internal):
19412 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19413 arguments, check that Lisp number is nonnegative, rather than
19414 silently wrapping negative numbers around. (Bug#8722)
19415 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19418 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19420 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19422 ccl: Add integer overflow checks.
19423 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19424 (IN_INT_RANGE): New macros.
19425 (ccl_driver): Use them to check for integer overflow when
19426 decoding a CCL program. Many of the new checks are whether XINT (x)
19427 fits in int; it doesn't always, on 64-bit hosts. The new version
19428 doesn't catch all possible integer overflows, but it's an
19429 improvement. (Bug#8719)
19431 * alloc.c (make_event_array): Use XINT, not XUINT.
19432 There's no need for unsigned here.
19434 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19435 This follows up to the 2011-05-06 change that substituted uintptr_t
19436 for EMACS_INT. This case wasn't caught back then.
19438 Rework Fformat to avoid integer overflow issues.
19439 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19440 now (part of C89). Include <verify.h>.
19441 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19442 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19443 (Fformat): Avoid the prepass trying to compute sizes; it was only
19444 approximate and thus did not catch overflow reliably. Instead, walk
19445 through the format just once, formatting and computing sizes as we go,
19446 checking for integer overflow at every step, and allocating a larger
19447 buffer as needed. Keep track separately whether the format is
19448 multibyte. Keep only the most-recently calculated precision, rather
19449 than them all. Record whether each argument has been converted to
19450 string. Use EMACS_INT, not int, for byte and char and arg counts.
19451 Support field widths and precisions larger than INT_MAX. Avoid
19452 sprintf's undefined behavior with conversion specifications such as %#d
19453 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19454 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19455 formatting out-of-range floating point numbers with int
19456 formats. (Bug#8668)
19458 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19460 * data.c: Avoid integer truncation in expressions involving floats.
19461 * data.c: Include <intprops.h>.
19462 (arith_driver): When there's an integer overflow in an expression
19463 involving floating point, convert the integers to floating point
19464 so that the resulting value does not suffer from catastrophic
19465 integer truncation. For example, on a 64-bit host (* 4
19466 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19467 Do not rely on undefined behavior after integer overflow.
19469 merge count_size_as_multibyte, parse_str_to_multibyte
19470 * character.c, character.h (count_size_as_multibyte):
19471 Rename from parse_str_to_multibyte; all uses changed.
19472 Check for integer overflow.
19473 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19474 since it's now a duplicate of the other. This is more of
19475 a character than a buffer op, so better that it's in character.c.
19476 * fns.c, print.c: Adjust to above changes.
19478 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19480 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19482 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19484 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19485 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19486 (x_clipboard_manager_save): Now static.
19487 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19489 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19490 (crypto_hash_function): Now static.
19491 Fix pointer signedness problems. Avoid unnecessary initializations.
19493 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19495 * termhooks.h (Vselection_alist): Make it terminal-local.
19497 * terminal.c (create_terminal): Initialize it.
19499 * xselect.c: Support for clipboard managers.
19500 (Vselection_alist): Move to termhooks.h as terminal-local var.
19501 (LOCAL_SELECTION): New macro.
19502 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19503 (symbol_to_x_atom): Remove gratuitous arg.
19504 (x_handle_selection_request, lisp_data_to_selection_data)
19505 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19506 (x_own_selection, x_get_local_selection, x_convert_selection):
19507 New arg, specifying work frame. Use terminal-local Vselection_alist.
19508 (some_frame_on_display): Delete unused function.
19509 (Fx_own_selection_internal, Fx_get_selection_internal)
19510 (Fx_disown_selection_internal, Fx_selection_owner_p)
19511 (Fx_selection_exists_p): New optional frame arg.
19512 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19513 (x_handle_selection_clear): Don't treat other terminals with the
19514 same keyboard specially. Use the terminal-local Vselection_alist.
19515 (x_clear_frame_selections): Use Frun_hook_with_args.
19517 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19519 * xterm.h: Add support for those atoms.
19521 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19523 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19524 (converted_selections, conversion_fail_tag): New global variables.
19525 (x_selection_request_lisp_error): Free the above.
19526 (x_get_local_selection): Remove unnecessary code.
19527 (x_reply_selection_request): Args changed; handle arbitrary array
19528 of converted selections stored in converted_selections.
19529 Separate the XChangeProperty and SelectionNotify steps.
19530 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19531 (x_convert_selection): New function.
19532 (x_handle_selection_event): Simplify.
19533 (x_get_foreign_selection): Don't ignore incoming requests while
19534 waiting for an answer; this will fail when we implement
19535 SAVE_TARGETS, and seems unnecessary anyway.
19536 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19537 (Vx_sent_selection_functions): Doc fix.
19539 2011-05-26 Leo Liu <sdl.web@gmail.com>
19541 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19543 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19545 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19547 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19548 for fringe update if it has periodic bitmap.
19549 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19550 and fringe_bitmap_periodic_p.
19552 * fringe.c (get_fringe_bitmap_data): New function.
19553 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19554 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19555 row. Mark glyph row for fringe update if periodicity changed.
19557 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19558 for fringe update unless it has periodic bitmap.
19560 2011-05-25 Kenichi Handa <handa@m17n.org>
19562 * xdisp.c (get_next_display_element): Set correct it->face_id for
19563 a static composition.
19565 2011-05-24 Leo Liu <sdl.web@gmail.com>
19568 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19570 * fns.c (crypto_hash_function, Fsha1): New function.
19571 (Fmd5): Use crypto_hash_function.
19572 (syms_of_fns): Add Ssha1.
19574 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19576 * gnutls.c: Remove unused macros.
19577 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19578 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19579 Remove macros that are defined and never used.
19580 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19582 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19584 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19585 (Fx_get_selection_internal): Minor cleanup.
19586 (Fx_own_selection_internal): Rename arguments for consistency with
19589 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19591 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19593 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19595 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19597 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19599 * dispnew.c (scrolling_window): Don't exclude the case that the
19600 last enabled row in the desired matrix touches the bottom boundary.
19602 2011-05-21 Glenn Morris <rgm@gnu.org>
19604 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19605 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19606 and add some more files.
19608 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19610 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19611 report_file_error introduced by the change from 2011-05-07.
19613 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19615 * systime.h (Time): Define only if emacs is defined.
19616 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19617 where the include path doesn't have X11/X.h by default. See
19618 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19620 2011-05-20 Kenichi Handa <handa@m17n.org>
19622 * composite.c (find_automatic_composition): Fix previous change.
19624 2011-05-20 Glenn Morris <rgm@gnu.org>
19626 * lisp.mk: New file, split from Makefile.in.
19627 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19628 (shortlisp): Remove.
19629 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19631 2011-05-19 Glenn Morris <rgm@gnu.org>
19633 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19634 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19635 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19636 (lisp): Set the order to that of loadup.el.
19637 (shortlisp): Make it a copy of $lisp.
19638 (SOME_MACHINE_LISP): Remove.
19639 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19640 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19642 2011-05-18 Kenichi Handa <handa@m17n.org>
19644 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19645 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19646 (find_automatic_composition): Mostly rewrite for efficiency.
19648 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19650 * makefile.w32-in: Update dependencies.
19652 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19654 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19655 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19657 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19659 Fix some integer overflow issues, such as string length overflow.
19661 * insdel.c (count_size_as_multibyte): Check for string overflow.
19663 * character.c (lisp_string_width): Check for string overflow.
19664 Use EMACS_INT, not int, for string indexes and lengths; in
19665 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19666 the resulting string length overflows an EMACS_INT; instead,
19667 report a string overflow if no precision given. When checking for
19668 precision exhaustion, use a check that cannot possibly have
19669 integer overflow. (Bug#8675)
19670 * character.h (lisp_string_width): Adjust to new signature.
19672 * alloc.c (string_overflow): New function.
19673 (Fmake_string): Use it. This doesn't change behavior, but saves
19674 a few bytes and will simplify future changes.
19675 * character.c (string_escape_byte8): Likewise.
19676 * lisp.h (string_overflow): New decl.
19678 Fixups, following up to the user-interface timestamp change.
19679 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19680 for UI timestamps, instead of unsigned long.
19681 * msdos.c (mouse_get_pos): Likewise.
19682 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19683 * w32gui.h (Time): Define by including "systime.h" rather than by
19684 declaring it ourselves. (Bug#8664)
19686 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19687 * image.c (clear_image_cache): Likewise.
19689 * term.c (term_mouse_position): Don't assume time_t wraparound.
19691 Be more systematic about user-interface timestamps.
19692 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19693 and sometimes 'EMACS_UINT', to represent these timestamps.
19694 This change causes it to use 'Time' uniformly, as that's what X uses.
19695 This makes the code easier to follow, and makes it easier to catch
19696 integer overflow bugs such as Bug#8664.
19697 * frame.c (Fmouse_position, Fmouse_pixel_position):
19698 Use Time, not unsigned long, for user-interface timestamps.
19699 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19700 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19701 * keyboard.h (last_event_timestamp): Likewise.
19702 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19703 * menu.h (xmenu_show): Likewise.
19704 * term.c (term_mouse_position): Likewise.
19705 * termhooks.h (struct input_event.timestamp): Likewise.
19706 (struct terminal.mouse_position_hook): Likewise.
19707 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19708 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19709 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19710 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19711 what it was before.
19712 * menu.h, termhooks.h: Include "systime.h", for Time.
19714 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19715 Don't assume that the difference between two unsigned long values
19716 can fit into an integer. At this point, we know button_down_time
19717 <= event->timestamp, so the difference must be nonnegative, so
19718 there's no need to cast the result if double-click-time is
19719 nonnegative, as it should be; check that it's nonnegative, just in
19720 case. This bug is triggered when events are more than 2**31 ms
19721 apart (about 25 days). (Bug#8664)
19723 * xselect.c (last_event_timestamp): Remove duplicate decl.
19724 (x_own_selection): Remove needless cast to unsigned long.
19726 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19727 that always fit in int. Use a sentinel instead of a counter, to
19728 avoid a temp and to allay GCC's concerns about possible int overflow.
19729 * frame.h (struct frame): Use int for menu_bar_items_used
19730 instead of EMACS_INT, since it always fits in int.
19732 * menu.c (grow_menu_items): Check for int overflow.
19734 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19736 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19737 Before, the code was not consistent. These values cannot exceed
19738 2**31 - 1 so there's no need to make them unsigned.
19739 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19740 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19741 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19743 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19745 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19746 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19747 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19748 presumably because the widths might not match.
19750 * window.c (size_window): Avoid needless test at loop start.
19752 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19754 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19756 2011-05-12 Drew Adams <drew.adams@oracle.com>
19758 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19760 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19762 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19763 `width' to `bar_area_x' and `bar_area_width', respectively.
19764 (x_scroll_run): Take account of fringe background extension.
19766 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19767 Rename local vars `left' and `width' to `bar_area_x' and
19768 `bar_area_width', respectively.
19769 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19770 background extension.
19772 2011-05-10 Jim Meyering <meyering@redhat.com>
19774 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19776 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19778 * image.c (Finit_image_library): Return t for built-in image types,
19779 like pbm and xbm. (Bug#8640)
19781 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19783 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19785 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19787 * w32console.c (Fset_screen_color): Doc fix.
19788 (Fget_screen_color): New function.
19789 (syms_of_ntterm): Defsubr it.
19791 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19792 unlink the temporary file if Fcall_process didn't create it in the
19794 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19795 child process will be redirected to a file specified with `:file'.
19796 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19797 cue to call_process_cleanup not to close that handle.
19799 2011-05-07 Ben Key <bkey76@gmail.com>
19801 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19802 one of two shell specific rules, either bootstrap-temacs-CMD or
19803 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19804 to the previous implementation of the bootstrap-temacs rule.
19805 The bootstrap-temacs-CMD rule is similar to the previous
19806 implementation of the bootstrap-temacs rule except that it
19807 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19810 These changes, along with some changes to nt/configure.bat,
19811 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19812 earlier fix to add support for --cflags and --ldflags options
19813 that include quotes so that it works whether make uses cmd or
19816 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19818 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19819 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19821 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19822 a string. Handle both cases.
19823 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19824 (Fdbus_register_method): Use Qinvalid_function.
19826 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19828 * makefile.w32-in: Update dependencies.
19829 (LISP_H): Add inttypes.h and stdin.h.
19830 (PROCESS_H): Add unistd.h.
19832 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19834 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19835 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19837 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19839 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19841 * term.c (vfatal): Remove stray call to va_end.
19842 It's not needed and the C Standard doesn't allow it here anyway.
19844 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19845 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19847 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19850 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19852 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19854 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19856 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19858 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19860 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19861 * charset.c (Fdefine_charset_internal): Don't initialize
19862 charset.code_space[15]. The value was garbage, on hosts with
19863 32-bit int (Bug#8600).
19865 * lread.c (read_integer): Be more consistent with string-to-number.
19866 Use string_to_number to do the actual conversion; this avoids
19867 rounding errors and fixes some other screwups. Without this fix,
19868 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19869 (digit_to_number): Move earlier, for benefit of read_integer.
19870 Return -1 if the digit is out of range for the base, -2 if it is
19871 not a digit in any supported base. (Bug#8602)
19873 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19875 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19876 to match comment at start of function. This also removes a
19877 GCC warning about overflow in a 32+64-bit port.
19879 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19881 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19882 Reported by Stefan Monnier in
19883 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19884 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19885 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19887 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19888 (EMACS_UINTPTR): Likewise, with uintptr_t.
19890 * lisp.h: Prefer 64-bit EMACS_INT if available.
19891 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19892 on 32-bit hosts that have 64-bit int, so that they can access
19894 However, temporarily disable this change unless the temporary
19895 symbol WIDE_EMACS_INT is defined.
19897 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19899 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19900 This removes an assumption that EMACS_INT and long are the same
19901 width as pointers. The assumption is true for Emacs porting targets
19902 now, but we want to make other targets possible.
19903 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19904 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19905 In the rest of the code, change types of integers that hold casted
19906 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19907 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19908 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19909 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19910 No need to cast type when ORing.
19911 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19912 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19913 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19914 assume EMACS_INT is the same width as char *.
19915 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19916 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19917 Remove no-longer-needed casts.
19918 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19919 (xg_tool_bar_help_callback, xg_make_tool_item):
19920 Use EMACS_INTPTR to hold an integer
19921 that will be cast to void *; this can avoid a GCC warning
19922 if EMACS_INT is not the same width as void *.
19923 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19924 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19925 (current_message_1, set_message_1):
19926 Use a local to convert to proper width without a cast.
19927 * xmenu.c (dialog_selection_callback): Likewise.
19929 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19930 Also, don't assume VALBITS / RAND_BITS is less than 5,
19931 and don't rely on undefined behavior when shifting a 1 left into
19933 * lisp.h (get_random): Change signature to match.
19935 * lread.c (hash_string): Use size_t, not int, for hash computation.
19936 Normally we prefer signed values; but hashing is special, because
19937 it's better to use unsigned division on hash table sizes so that
19938 the remainder is nonnegative. Also, size_t is the natural width
19939 for hashing into memory. The previous code used 'int', which doesn't
19940 retain enough info to hash well into very large tables.
19941 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19943 * dbusbind.c: Don't possibly lose pointer info when converting.
19944 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19945 Use XPNTR rather than XHASH, so that the high-order bits of
19946 the pointer aren't lost when converting through void *.
19948 * eval.c (Fautoload): Don't double-shift a pointer.
19950 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19952 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19954 * gnutls.c (DEF_GNUTLS_FN):
19955 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19957 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19959 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19962 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19964 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19965 New version that can reserve upto 2GB of heap space.
19967 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19969 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

20033 * process.c: Include lisp.h before w32.h, not after.
20034 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20035 instead of gnutls_record_check_pending.

20039 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20041 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

20087 rather than `XVECTOR (FOO)->size'.
20089 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20090 inttypes.h, as a gnulib replacement is used if it not available in
20093 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20095 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

20110 aborting when %lld or %lll format is passed.
20111 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20112 %llo or %llx format is passed. (Bug#8545)
20114 * window.c (window_scroll_line_based): Use a marker instead of
20115 simple variables to record original value of point. (Bug#7952)
20117 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20118 produced by %s or %c overflows available buffer space. (Bug#8545)
20120 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20122 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20123 (SIZE_MAX): Move defn after all includes, as they might #define it.
20125 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20127 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20129 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20131 * keyboard.c (Qdelayed_warnings_hook): Define.
20132 (command_loop_1): Run `delayed-warnings-hook'
20133 if Vdelayed_warnings_list is non-nil.
20134 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20135 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20137 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20139 * doprnt.c (doprnt): Don't return value smaller than the buffer
20140 size if the message was truncated. (Bug#8545).
20142 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20144 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20145 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20147 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20149 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20151 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20153 * makefile.w32-in: Update dependencies.
20155 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20157 Improve `doprnt' and its usage. (Bug#8545)
20158 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20159 `format_end'. Remove support for %l as a conversion specifier.
20160 Don't use xrealloc. Improve diagnostics when the %l size modifier
20161 is used. Update the commentary.
20163 * eval.c (verror): Simplify calculation of size_t.
20165 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20168 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20170 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20173 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20175 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20176 This makes this file independent of the recent pseudovector change.
20178 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20180 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20182 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20183 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20184 Remove unused local.
20185 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20187 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20188 GCC 4.6.0 optimizes based on type-based alias analysis.
20189 For example, if b is of type struct buffer * and v of type struct
20190 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20191 != &v->size, and therefore "v->size = 1; b->size = 2; return
20192 v->size;" must therefore return 1. This assumption is incorrect
20193 for Emacs, since it type-puns struct Lisp_Vector * with many other
20194 types. To fix this problem, this patch adds a new type struct
20195 vectorlike_header that documents the constraints on layout of vectors
20196 and pseudovectors, and helps optimizing compilers not get fooled
20197 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20198 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20199 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20201 (XSETPVECTYPE): Rewrite in terms of new macro.
20202 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20203 This is a bit clearer, and further avoids the possibility of
20204 undesirable aliasing.
20205 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20206 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20207 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20208 since Lisp_Subr is a special case (no "next" field).
20209 (ASIZE): Now uses header.size rather than size.
20210 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20211 to avoid the hassle of writing XVECTOR (foo)->header.size.
20212 (struct vectorlike_header): New type.
20213 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20214 object, to help avoid aliasing.
20215 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20216 (SUBRP): Likewise, since Lisp_Subr is a special case.
20217 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20218 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20219 (struct Lisp_Hash_Table): Combine first two members into a single
20220 struct vectorlike_header member. All uses of "size" and "next" members
20221 changed to be "header.size" and "header.next".
20222 * buffer.h (struct buffer): Likewise.
20223 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20224 * frame.h (struct frame): Likewise.
20225 * process.h (struct Lisp_Process): Likewise.
20226 * termhooks.h (struct terminal): Likewise.
20227 * window.c (struct save_window_data, struct saved_window): Likewise.
20228 * window.h (struct window): Likewise.
20229 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20230 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20231 * buffer.c (init_buffer_once): Likewise.
20232 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20234 * process.c (Fformat_network_address): Use local var for size,
20237 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20239 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20240 * data.c (atof): Remove decl; no longer used or needed.
20241 (digit_to_number): Move to lread.c.
20242 (Fstring_to_number): Use new string_to_number function, to be
20243 consistent with how the Lisp reader treats infinities and NaNs.
20244 Do not assume that floating-point numbers represent EMACS_INT
20245 without losing information; this is not true on most 64-bit hosts.
20246 Avoid double-rounding errors, by insisting on integers when
20247 parsing non-base-10 numbers, as the documentation specifies.
20248 * lisp.h (string_to_number): New decl, replacing ...
20249 (isfloat_string): Remove.
20250 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20251 (read1): Do not accept +. and -. as integers; this
20252 appears to have been a coding error. Similarly, do not accept
20253 strings like +-1e0 as floating point numbers. Do not report
20254 overflow for integer overflows unless the base is not 10 which
20255 means we have no simple and reliable way to continue.
20256 Break out the floating-point parsing into a new
20257 function string_to_number, so that Fstring_to_number parses
20258 floating point numbers consistently with the Lisp reader.
20259 (digit_to_number): Move here from data.c. Make it static inline.
20260 (E_CHAR, EXP_INT): Remove, replacing with ...
20261 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20262 (string_to_number): New function, replacing isfloat_string.
20263 This function checks for valid syntax and produces the resulting
20264 Lisp float number too. Rework it so that string-to-number
20265 no longer mishandles examples like "1.0e+". Use strtoumax,
20266 so that overflow for non-base-10 numbers is reported only when
20267 there's no portable and simple way to convert to floating point.
20269 * textprop.c (set_text_properties_1): Rewrite for clarity,
20270 and to avoid GCC warning about integer overflow.
20272 * intervals.h (struct interval): Use EMACS_INT for members
20273 where EMACS_UINT might cause problems. See
20274 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20275 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20276 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20278 (offset_intervals): Tell GCC not to worry about length overflow
20279 when negating a negative length.
20281 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20282 (overrun_check_free): Likewise.
20284 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20285 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20288 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20289 (gnutls_make_error): Rename local to avoid shadowing.
20290 (gnutls_emacs_global_deinit): ifdef out; not used.
20291 (Fgnutls_boot): Use const for pointer to readonly storage.
20292 Comment out unused local. Fix pointer signedness problems.
20294 * lread.c (openp): Don't stuff size_t into an 'int'.
20295 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20296 about possible signed overflow.
20298 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20299 (GDK_KEY_g): Don't define if already defined.
20300 (xg_prepare_tooltip): Avoid pointer signedness problem.
20301 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20303 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20304 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20306 * xfns.c (Fx_window_property): Simplify a bit,
20307 to make a bit faster and to avoid GCC 4.6.0 warning.
20308 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20310 * fns.c (internal_equal): Don't assume size_t fits in int.
20312 * alloc.c (compact_small_strings): Tighten assertion a little.
20314 Replace pEd with more-general pI, and fix some printf arg casts.
20315 * lisp.h (pI): New macro, generalizing old pEd macro to other
20316 conversion specifiers. For example, use "...%"pI"d..." rather
20317 than "...%"pEd"...".
20318 (pEd): Remove. All uses replaced with similar uses of pI.
20319 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20320 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20321 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20322 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20323 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20324 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20325 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20327 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20328 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20329 * print.c (safe_debug_print, print_object): Likewise.
20330 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20332 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20333 avoiding the 0 flag, which is not portable.
20334 * process.c (Fmake_network_process): Use pI to avoid cast.
20335 * region-cache.c (pp_cache): Likewise.
20336 * xdisp.c (decode_mode_spec): Likewise.
20337 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20338 behavior on 64-bit hosts with printf arg.
20339 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20340 (x_stop_queuing_selection_requests): Likewise.
20341 (x_get_window_property): Don't truncate byte count to an 'int'
20344 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20345 here, since it parses constructs like leading '-' and spaces,
20346 which are not wanted; and it overflows with large numbers.
20347 Instead, simply match F[0-9]+, which is what is wanted anyway.
20349 * alloc.c: Remove unportable assumptions about struct layout.
20350 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20351 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20352 (allocate_vectorlike, make_pure_vector): Use the new macros,
20353 plus offsetof, to remove unportable assumptions about struct layout.
20354 These assumptions hold on all porting targets that I know of, but
20355 they are not guaranteed, they're easy to remove, and removing them
20356 makes further changes easier.
20358 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20359 This doesn't fix a bug but makes the code clearer.
20360 (string_overrun_cookie): Now const. Use initializers that
20361 don't formally overflow signed char, to avoid warnings.
20362 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20363 can cause Emacs to crash when string overrun checking is enabled.
20364 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20365 multiple of sizeof (EMACS_INT); it need not be, if
20366 alignof(EMACS_INT) < sizeof (EMACS_INT).
20367 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20369 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20371 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20373 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20375 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20376 supposed to be handshaking. (Bug#8556)
20377 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20379 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
20381 * lisp.h (Qdebug): List symbol.
20382 * eval.c (Qdebug): Restore global linkage.
20383 * keyboard.c (debug-on-event): New variable.
20384 (handle_user_signal): Break into debugger when debug-on-event
20385 matches the current signal symbol.

20950 * xfaces.c (face_at_string_position):
20951 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

21140 to see whether these functions can be called from other modules.
21141 DEFUN now defines a static function. To make the function external
21142 so that it can be used in other C modules, use the new macro DEFUE.

21218 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21220 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21221 since callers should never pass a negative size.
21222 Change the signature to match that of plain 'read' and 'write'; see
21223 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21224 * lisp.h: Update prototypes of emacs_write and emacs_read.
21226 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21228 * xdisp.c (redisplay_window): Don't try to determine the character
21229 position of the scroll margin if the window start point w->startp
21230 is outside the buffer's accessible region. (Bug#8468)
21232 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21234 Fix write-region and its subroutines for buffers > 2GB.
21235 * fileio.c (a_write, e_write): Modify declaration of arguments and
21236 local variables to support buffers larger than 2GB.
21237 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21239 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21240 argument, local variables, and return value.
21242 * lisp.h: Update prototypes of emacs_write and emacs_read.
21244 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21246 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21248 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

21252 * xdisp.c (vmessage): Use a better test for character truncation.
21254 * charset.c (load_charset_map): <, not <=, for optimization,

21264 * callint.c (Fcall_interactively): <, not <=, for optimization.
21265 (Fcall_interactively): Count the number of arguments produced,
21266 not the number of arguments given. This is simpler and lets GCC
21267 4.6.0 generate slightly better code.
21269 * ftfont.c: Distingish more carefully between FcChar8 and char.
21270 The previous code passed unsigned char * to a functions like
21271 strlen and xstrcasecmp that expect char *, which does not
21272 conform to the C standard.
21273 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21274 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21275 char * when the C standard requires it.
21277 * keyboard.c (read_char): Remove unused var.
21279 * eval.c: Port to Windows vsnprintf (Bug#8435).
21280 Include <limits.h>.

21282 (verror): Do not give up if vsnprintf returns a negative count.
21283 Instead, grow the buffer. This ports to Windows vsnprintf, which
21284 does not conform to C99. Problem reported by Eli Zaretskii.
21285 Also, simplify the allocation scheme, by avoiding the need for
21286 calling realloc, and removing the ALLOCATED variable.
21288 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21290 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21291 But keep the doprint source code for now, as we might revamp it
21292 and use it again (Bug#8435).
21293 * lisp.h (doprnt): Remove.
21294 * Makefile.in (base_obj): Remove doprnt.o.
21295 * deps.mk (doprnt.o): Remove.
21297 error: Print 32- and 64-bit integers portably (Bug#8435).
21298 Without this change, on typical 64-bit hosts error ("...%d...", N)
21299 was used to print both 32- and 64-bit integers N, which relied on
21300 undefined behavior.
21301 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21302 * lisp.h (error, verror): Mark as printf-like functions.
21303 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21304 Report overflow in size calculations when allocating printf buffer.
21305 Do not truncate output string at its first null byte.
21306 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21307 Truncate the output at a character boundary, since vsnprintf does not
21309 * charset.c (check_iso_charset_parameter): Convert internal
21310 character to string before calling 'error', since %c now has the
21312 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21313 overflow when computing char to be passed to 'error'. Do not
21314 pass Lisp_Object to 'error'; pass the integer instead.
21315 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21316 formatted with plain %d.
21318 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21320 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21322 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21324 * xterm.c (x_catch_errors): Remove duplicate declaration.
21326 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21328 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21330 2011-04-10 Jim Meyering <meyering@redhat.com>
21332 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21333 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21334 return ssize_t not "int", and use size_t as the buffer length.
21335 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21336 * gnutls.h: Update declarations.
21337 * process.c (read_process_output): Use ssize_t, to match.
21338 (send_process): Likewise.

21342 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21344 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21346 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21347 Use unsigned char, to match FcChar8 type definition.
21349 * xterm.c (handle_one_xevent):
21350 * xmenu.c (create_and_show_popup_menu):
21351 * xselect.c (x_decline_selection_request)
21352 (x_reply_selection_request): Avoid type-punned deref of X events.
21354 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21356 Fix some uses of `int' instead of EMACS_INT.
21357 * search.c (string_match_1, fast_string_match)

21361 (Fmatch_data): Make some `int' variables be EMACS_INT.
21363 * xdisp.c (display_count_lines): 3rd argument and return value now
21364 EMACS_INT. All callers changed.
21365 (pint2hrstr): Last argument is now EMACS_INT.

21380 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21381 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21383 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21384 (encode_invocation_designation): Last argument P_NCHARS is now
21386 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21387 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21389 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21392 * ccl.c (Fccl_execute_on_string): Declare some variables
21395 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

21410 instead of using internal_with_output_to_temp_buffer.
21411 (Qhelp_form_show): New var.
21412 (syms_of_keyboard): Use DEFSYM macro.
21414 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21437 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21439 * xdisp.c (vmessage): Mark as a printf-like function.
21441 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

21448 to system-supplied API.
21450 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21452 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21453 This avoids several warnings with gcc -Wstrict-overflow.
21454 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21455 directly, rather than having caller test rule sign. This avoids
21456 some unnecessary tests.
21457 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21458 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21459 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21461 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21462 (xfont_open): Avoid unnecessary tests.
21464 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21466 * composite.h, composite.c (composition_gstring_put_cache):
21467 Use EMACS_INT, not int, for length.

21470 breaking out part of COMPOSITION_DECODE_RULE.
21471 (COMPOSITION_DECODE_RULE): Use it.
21472 * composite.c (get_composition_id): Remove unused local vars,
21473 by using the new macro.
21475 * textprop.c (set_text_properties_1): Change while to do-while,
21476 since the condition is always true at first.
21478 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21479 (interval_deletion_adjustment): Return unsigned value.
21482 * process.c (list_processes_1, create_pty, read_process_output):

21496 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21498 * print.c (print_error_message): Avoid int overflow.
21500 * font.c (font_list_entities): Redo for clarity,
21501 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21503 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21504 (font_score): Avoid potential overflow in diff calculation.
21506 * fns.c (substring_both): Remove var that is set but not used.
21507 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21509 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21511 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21512 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21513 can always succeed if overflow has undefined behavior.
21515 * search.c (boyer_moore, wordify): Remove vars set but not used.
21516 (wordify): Omit three unnecessary tests.
21518 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21519 All callers changed. This avoids the need for an unused var.
21521 * casefiddle.c (casify_region): Remove var that is set but not used.
21523 * dired.c (file_name_completion): Remove var that is set but not used.
21525 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21527 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21528 (Finsert_file_contents): Remove unnecessary code checking fd.
21530 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21531 Check for integer overflow on size calculations.
21533 * buffer.c (Fprevious_overlay_change): Remove var that is set
21536 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21537 Remove vars that are set but not used.
21538 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21539 (timer_check_2): Mark vars as initialized.
21541 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21543 * image.c (lookup_image): Remove var that is set but not used.
21544 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21546 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21547 that are set but not used.
21549 * xfns.c (make_invisible_cursor): Don't return garbage
21550 if XCreateBitmapFromData fails (Bug#8410).
21552 * xselect.c (x_get_local_selection, x_handle_property_notify):
21553 Remove vars that are set but not used.
21555 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21556 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21558 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21559 Remove var that is set but not used.
21560 (scroll_bar_windows_size): Now size_t, not int.
21561 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21562 Check for overflow.
21564 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21565 (map_tty_color) [!defined MSDOS]: Likewise.
21567 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21569 * coding.c: Remove vars that are set but not used.
21570 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21571 All callers changed.
21572 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21573 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21574 (decode_coding_charset): Remove vars that are set but not used.
21576 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21577 that is set but not used.
21579 * print.c (print_object): Remove var that is set but not used.
21581 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21582 The gnulib version avoids calling malloc in the usual case,
21583 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21584 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21585 * filelock.c (current_lock_owner): Likewise.
21586 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21587 * sysdep.c: Include allocator.h, careadlinkat.h.
21588 (emacs_no_realloc_allocator): New static constant.
21589 (emacs_readlink): New function.
21590 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21591 ../lib/careadlinkat.h.
21593 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21595 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21596 first non-nil return value).
21598 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21600 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21601 if not defined (Bug#8403).

21610 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21611 and thereabouts. All callers changed.
21612 (get_per_char_metric): Remove parameter `f', unused since
21613 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21615 2011-04-02 Jim Meyering <meyering@redhat.com>
21617 do not dereference NULL upon failed strdup
21618 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21619 (ns_get_family): Likewise.
21621 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21623 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21625 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21627 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21630 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21632 Add lexical binding.
21634 * window.c (Ftemp_output_buffer_show): New fun.

21645 (syms_of_lread): Declare `lexical-binding'.
21647 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21649 * keyboard.c (eval_dyn): New fun.
21650 (menu_item_eval_property): Use it.
21652 * image.c (parse_image_spec): Use Ffunctionp.
21654 * fns.c (concat, mapcar1): Accept byte-code-functions.
21656 * eval.c (Fsetq): Handle lexical vars.
21657 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21658 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21659 (FletX, Flet): Obey lexical binding.
21660 (Fcommandp): Handle closures.
21661 (Feval): New `lexical' arg.
21662 (eval_sub): New function extracted from Feval. Use it almost
21663 everywhere where Feval was used. Look up vars in lexical env.
21665 (Ffunctionp): Move from subr.el.
21666 (Ffuncall): Handle closures.
21667 (apply_lambda): Remove `eval_flags'.
21668 (funcall_lambda): Handle closures and new byte-code-functions.
21669 (Fspecial_variable_p): New function.
21670 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21671 but without exporting it to Lisp.
21673 * doc.c (Fdocumentation, store_function_docstring):
21674 * data.c (Finteractive_form): Handle closures.
21676 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21679 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21681 (exec_byte_code): New function extracted from Fbyte_code to handle new
21682 calling convention for byte-code-functions. Add new byte-codes.
21684 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21686 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21688 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21690 * xdisp.c (redisplay_internal): Fix prototype.
21692 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21694 * xdisp.c (SCROLL_LIMIT): New macro.
21695 (try_scrolling): Use it when setting scroll_limit.
21696 Limit scrolling to 100 screen lines.
21697 (redisplay_window): Even when falling back on "recentering",
21698 position point in the window according to scroll-conservatively,
21699 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21701 (try_scrolling): When point is above the window, allow searching
21702 as far as scroll_max, or one screenful, to compute vertical
21703 distance from PT to the scroll margin position. This prevents
21704 try_scrolling from unnecessarily failing when
21705 scroll-conservatively is set to a value slightly larger than the
21706 window height. Clean up the case of PT below the margin at bottom
21707 of window: scroll_max can no longer be INT_MAX. When aggressive
21708 scrolling is in use, don't let point enter the opposite scroll
21709 margin as result of the scroll.
21710 (syms_of_xdisp) <scroll-conservatively>: Document the
21711 threshold of 100 lines for never-recentering scrolling.

21718 (message_log_check_duplicate): Remove parameters `prev_bol' and
21719 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21720 (redisplay_internal): Remove parameter `preserve_echo_area',
21721 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21723 * indent.c (Fvertical_motion):
21724 * window.c (window_scroll_pixel_based, Frecenter):
21725 Don't pass `need_y_p' to `move_it_by_lines'.
21727 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21729 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21730 steal a few bits to be more compact.
21731 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21732 Remove unneeded casts.
21734 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21736 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21738 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21739 binding" message (bug#7967).
21741 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21743 Fix more problems found by GCC 4.6.0's static checks.
21745 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21746 Remove unused local var.
21748 * editfns.c (Fmessage_box): Remove unused local var.
21750 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21751 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21752 Omit unused local vars.
21753 * window.c (shrink_windows): Omit unused local var.
21754 * menu.c (digest_single_submenu): Omit unused local var.
21755 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21756 Omit unused local var.
21758 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21759 Don't assume string length fits in int.
21760 (keyremap_step, read_key_sequence): Use size_t for sizes.
21761 (read_key_sequence): Don't check last_real_key_start redundantly.
21763 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21764 instead of alloca (Bug#8344).
21766 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21767 (Fbacktrace_frame): Don't assume nframes fits in int.
21769 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21771 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21774 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21776 * cm.c (calccost): Turn while-do into do-while, for clarity.
21778 * keyboard.c (syms_of_keyboard): Use the same style as later
21779 in this function when indexing through an array. This also
21780 works around GCC bug 48267.
21782 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21784 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

21787 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21789 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21790 This avoids undefined behavior on integer overflow, and is a bit
21791 more convenient anyway since it is compared to a size_t variable.
21793 Variadic C functions now count arguments with size_t, not int.
21794 This avoids an unnecessary limitation on 64-bit machines, which
21795 caused (substring ...) to crash on large vectors (Bug#8344).
21796 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21797 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21798 All variadic functions and their callers changed accordingly.
21799 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21803 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21804 (funcall_lambda, mark_backtrace): Likewise.
21805 * fns.c (concat): Likewise.
21806 * frame.c (x_set_frame_parameters): Likewise.
21807 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21808 0 if not found, not -1. All callers changed.
21810 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21811 (stack_copy_size): Now size_t, not int.
21812 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21814 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21816 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21817 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21818 All callers changed.
21820 * lisp.h (multibyte_char_to_unibyte):
21821 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21822 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21823 * character.h (CHAR_TO_BYTE8):
21824 * cmds.c (internal_self_insert):
21825 * editfns.c (general_insert_function):
21826 * keymap.c (push_key_description):
21827 * search.c (Freplace_match):
21828 * xdisp.c (message_dolog, set_message_1): All callers changed.
21830 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21832 * keyboard.c (safe_run_hook_funcall): New function.
21833 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21834 don't set the hook to nil, but remove the offending function instead.
21835 (Qcommand_hook_internal): Remove, unused.
21836 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21837 Vcommand_hook_internal.
21839 * eval.c (enum run_hooks_condition): Remove.
21840 (funcall_nil, funcall_not): New functions.
21841 (run_hook_with_args): Call each function through a `funcall' argument.
21842 Remove `cond' argument, now redundant.
21843 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21844 (Frun_hook_with_args_until_failure): Adjust accordingly.
21845 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21847 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21849 * dispextern.h (string_buffer_position): Remove declaration.
21851 * print.c (strout): Remove parameter `multibyte', unused since
21852 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21854 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21855 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21856 All callers changed.
21858 * w32.c (_wsa_errlist): Use braces for struct initializers.
21860 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21861 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21862 All callers changed.
21863 (string_buffer_position): Likewise. Also, make static (it's never
21864 used outside xdisp.c).
21865 (cursor_row_p): Remove parameter `w', unused since
21866 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21868 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21869 All callers changed.
21871 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21873 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21878 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
21879 (ns_update_auto_hide_menu_bar): New functions.
21880 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21884 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21886 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21888 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21890 2011-03-27 Glenn Morris <rgm@gnu.org>

21902 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21904 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21906 * w32.c (read_unc_volume): Use parameter `henum', instead of
21907 global variable `wget_enum_handle'.
21909 * keymap.c (describe_vector): Remove parameters `indices' and
21910 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21922 * xmenu.c (show_help_event, menu_help_callback):
21923 Adjust calls to `show_help_echo'.
21925 * gtkutil.c (xg_maybe_add_timer):
21926 * keyboard.c (readable_events):
21927 * process.c (wait_reading_process_output):
21928 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21930 * insdel.c (adjust_markers_gap_motion):
21931 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

22005 2011-03-23 Julien Danjou <julien@danjou.info>
22007 * term.c (Fsuspend_tty, Fresume_tty):
22008 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22009 * window.c (temp_output_buffer_show):

22015 * cmds.c (internal_self_insert):
22016 * callint.c (Fcall_interactively):
22017 * buffer.c (Fkill_all_local_variables):
22018 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22020 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22021 unconditionally since it does the check itself.
22023 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22025 Fix more problems found by GCC 4.5.2's static checks.
22027 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22028 the first time through the loop, since we know p0 < p1 then.
22029 This also avoids a gcc -Wstrict-overflow warning.
22031 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22032 leading to a memory leak, possible in functions like
22033 load_charset_map_from_file that can allocate an unbounded number
22034 of objects (Bug#8318).
22036 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22037 that could (at least in theory) be that large.
22039 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22040 This is less likely to overflow, and avoids undefined behavior if
22041 overflow does occur. All callers changed. Use strtoul to scan
22042 for the unsigned long integer.
22043 (pint2hrstr): Simplify and tune code slightly.
22044 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22054 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22057 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22059 * process.c (Fmake_network_process): Use socklen_t, not int,
22060 where POSIX says socklen_t is required in portable programs.
22061 This fixes a porting bug on hosts like 64-bit HP-UX, where
22062 socklen_t is wider than int (Bug#8277).
22063 (Fmake_network_process, server_accept_connection):
22064 (wait_reading_process_output, read_process_output):
22067 * process.c: Rename or move locals to avoid shadowing.

22074 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22075 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22077 Make tparam.h and terminfo.c consistent.
22078 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22079 Include tparam.h instead, since it declares them.
22080 * cm.h (PC): Remove extern decl; tparam.h now does this.
22081 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22082 * terminfo.c: Include tparam.h, to check interfaces.
22083 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22084 (tparam): Adjust signature to match interface in tparam.h;
22085 this removes some undefined behavior. Check that outstring and len
22086 are zero, which they always are with Emacs.
22087 * tparam.h (PC, BC, UP): New extern decls.
22089 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22090 (xftfont_open): Rename locals to avoid shadowing.
22092 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22093 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22094 (OTF_TAG_SYM): Omit macro if not needed.
22095 (ftfont_list): Remove unused local.
22096 (get_adstyle_property, ftfont_pattern_entity):
22097 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22098 Rename locals to avoid shadowing.
22100 * xfont.c (xfont_list_family): Mark var as initialized.
22102 * xml.c (make_dom): Now static.
22104 * composite.c (composition_compute_stop_pos): Rename local to
22106 (composition_reseat_it): Remove unused locals.
22107 (find_automatic_composition, composition_adjust_point): Likewise.
22108 (composition_update_it): Mark var as initialized.
22109 (find_automatic_composition): Mark vars as initialized,
22110 with a FIXME (Bug#8290).
22112 character.h: Rename locals to avoid shadowing.
22113 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22114 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22115 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22116 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22117 to avoid shadowing.
22119 * textprop.c (property_change_between_p): Remove; unused.
22121 * intervals.c (interval_start_pos): Now static.
22123 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
22125 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
22126 Rename locals to avoid shadowing.
22128 * sound.c (wav_play, au_play, Fplay_sound_internal):
22129 Fix pointer signedness.
22130 (alsa_choose_format): Remove unused local var.
22131 (wav_play): Initialize a variable to 0, to prevent undefined
22132 behavior (Bug#8278).
22134 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22136 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22138 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22139 clobbering (Bug#8298).
22140 * sysdep.c (sys_subshell): Likewise.
22141 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22143 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22144 This should get cleaned up, so that child_setup has the
22145 same signature on all platforms.
22147 * callproc.c (call_process_cleanup): Now static.
22148 (relocate_fd): Rename locals to avoid shadowing.
22150 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22152 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22153 not to be necessary, and produces flickering.
22155 2011-03-20 Glenn Morris <rgm@gnu.org>
22157 * config.in: Remove file.
22159 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22161 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22162 are now in src/globals.h.

22261 * lisp.h: ... to here, so that it can be checked.
22263 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
22264 (Fdefvar): Rewrite so as not to use empty "else".

22278 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22279 some of which prompt warnings from gcc -Wbad-function-cast.
22280 (Fformat_time_string, Fencode_time, Finsert_char):
22281 (Ftranslate_region_internal, Fformat):
22282 Rename or remove local vars to avoid shadowing.

22312 avoids undefined behavior in theory.
22314 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22316 Use functions, not macros, for up- and down-casing (Bug#8254).
22317 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22318 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22319 to use the following functions instead of these macros.
22320 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22321 EMACS_INT, since callers assume the returned value fits in int.
22322 (upcase1): Likewise, for UPCASE_TABLE.
22323 (uppercasep, lowercasep, upcase): New static inline functions.
22324 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22330 (regex_compile, re_search_2, re_match_2_internal):
22331 Remove unused local vars.

22333 which gcc can warn about.
22334 (regex_compile, re_match_2_internal): Mark locals as initialized.
22335 (RETALLOC_IF): Define only if needed.
22336 (WORDCHAR_P): Likewise. This one is never needed, but is used
22337 only in a comment talking about a compiler bug, so put inside
22338 the #if 0 of that comment.
22339 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22340 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22343 * search.c (boyer_moore): Rename locals to avoid shadowing.

22358 Rename locals to avoid shadowing.
22359 (Fvertical_motion): Mark locals as initialized.
22361 * casefiddle.c (casify_object, casify_region): Now static.
22362 (casify_region): Mark local as initialized.

22366 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22367 New macros, so that the caller can use some names other than
22368 gcpro1, gcpro2, etc.
22369 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22371 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22372 argument, for consistency with GCPRO2_VAR, etc: it is now the
22373 prefix of the variable, not the variable itself. All uses
22375 * dired.c (directory_files_internal, file_name_completion):
22376 Rename locals to avoid shadowing.
22378 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22379 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22380 dired.c's scmp function, had undefined behavior.
22381 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22382 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22383 * buffer.h: ... to here, because these macros use current_buffer,
22384 and the new implementation with inline functions needs to have
22385 current_buffer in scope now, rather than later when the macros
22387 (downcase, upcase1): New static inline functions.
22388 (DOWNCASE, UPCASE1): Reimplement using these functions.
22389 This avoids undefined behavior in expressions like
22390 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22391 from race conditions in accessing the global variables
22392 case_temp1 and case_temp2.
22393 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22394 * lisp.h (case_temp1, case_temp2): Remove their decls.
22395 * character.h (ASCII_CHAR_P): Move from here ...
22396 * lisp.h: ... to here, so that the inline functions mentioned
22397 above can use them.
22399 * dired.c (directory_files_internal_unwind): Now static.
22401 * fileio.c (file_name_as_directory, directory_file_name):
22402 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22404 (file_name_as_directory): Use const pointers when appropriate.
22405 (Fexpand_file_name): Likewise. In particular, newdir might
22406 point at constant storage, so make it a const pointer.
22407 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22408 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22410 (Fset_file_times, Finsert_file_contents, auto_save_error):

22415 to avoid shadowing.
22417 * marker.c (bytepos_to_charpos): Remove; unused.
22419 * lisp.h (verify_bytepos, count_markers): New decls,
22420 so that gcc does not warn that these functions aren't declared.
22422 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22423 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22424 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22425 (copy_text): Remove unused local var.
22427 * filelock.c (within_one_second): Now static.
22428 (lock_file_1): Rename local to avoid shadowing.
22430 * buffer.c (fix_overlays_before): Mark locals as initialized.
22431 (fix_start_end_in_overlays): Likewise. This function should be
22432 simplified by using pointers-to-pointers, but that's a different
22434 (switch_to_buffer_1): Now static.
22435 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22436 (report_overlay_modification): Rename locals to avoid shadowing.
22438 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22439 Fix pointer signedness issue.
22440 (sys_subshell): Mark local as volatile if checking for lint,
22441 to suppress a gcc -Wclobbered warning that does not seem to be right.
22442 (MAXPATHLEN): Define only if needed.
22444 * process.c (serial_open, serial_configure): Move decls from here ...
22445 * systty.h: ... to here, so that they can be checked.
22447 * fns.c (get_random, seed_random): Move extern decls from here ...
22448 * lisp.h: ... to here, so that they can be checked.
22450 * sysdep.c (reset_io): Now static.
22451 (wait_for_termination_signal): Remove; unused.
22453 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22454 (copy_keymap_item, append_key, push_text_char_description):
22456 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22457 (DENSE_TABLE_SIZE): Remove; unused.
22458 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22459 (describe_map_tree):
22460 Rename locals to avoid shadowing.
22462 * keyboard.c: Declare functions static if they are not used elsewhere.
22463 (echo_char, echo_dash, cmd_error, top_level_2):
22464 (poll_for_input, handle_async_input): Now static.
22465 (read_char, kbd_buffer_get_event, make_lispy_position):
22466 (make_lispy_event, make_lispy_movement, apply_modifiers):
22467 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
22468 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
22469 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
22470 (read_key_sequence, read_char): Mark locals as initialized.

22547 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22548 These macros can no longer be used for assignment.
22550 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

22606 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
22608 Improve quality of tests for time stamp overflow.
22609 For example, without this patch (encode-time 0 0 0 1 1
22610 1152921504606846976) returns the obviously-bogus value (-948597
22611 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22612 reports time overflow. See
22613 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
22614 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
