3 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
4 too so that these builds can use Cygwin's file conversion
5 functions. (We've been building and linking cygw32.o all along
6 and just not using it.)
8 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
10 File synchronization fixes (Bug#13944).
11 * Makefile.in (LIB_FDATASYNC): New macro.
13 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
14 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
15 Don't worry about HAVE_FSYNC, since a substitute fsync is
16 available if the system lacks one.
17 (Fwrite_regin): Retry fsync if interrupted.
19 2013-03-13 Eli Zaretskii <eliz@gnu.org>
21 * w32term.c (w32_read_socket): If we Emacs frame is being
22 activated, call w32fullscreen_hook, to make sure the new frame
23 dimensions are in effect. (Bug#13937)
25 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
27 * xdisp.c (init_iterator): Simplify because both character and byte
28 positions are either specified or -1. Add eassert. Adjust comment.
29 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
30 character and byte positions can be obtained from marker.

47 a function pointer type; the C Standard requires this.
49 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
50 Include <sys/param.h> unconditionally, as that works elsewhere and
51 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
52 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

133 (adjust_after_insert): Call adjust_after_replace with the new arg
136 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
138 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
139 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
140 from Elisp via unread-command-events.
142 * keyboard.c (access_keymap_keyremap): Accept nil return value from
143 functions to mean "no change".
145 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
147 region-cache.c, scroll.c, search.c: Use bool for booleans.
148 * lisp.h (compile_pattern):
149 * scroll.c (do_scrolling, do_direct_scrolling):
150 * search.c (struct regexp_cache, compile_pattern_1)
151 (compile_pattern, string_match_1, search_command)
152 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
153 (search_regs_saved, Fregexp_quote):
154 Use bool for boolean.
155 * region-cache.c (region_cache_forward, region_cache_backward):
156 Fix comments to match code: these functions return int, not boolean.
158 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
160 * search.c (find_newline): Accept start and end byte positions
161 as arguments and allow -1 if not known.

167 Adjust call to find_newline.
168 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

170 position, where appropriate.
171 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
172 (get_visually_first_element, move_it_vertically_backward): Likewise.
173 Obtain byte position from the display iterator, where appropriate.
175 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

193 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
195 * bidi.c (bidi_fetch_char): Swap first and second arguments
196 to match other functions accepting character and byte positions.
198 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

200 when you need just to move to the previous buffer position.
201 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
203 2013-03-07 Eli Zaretskii <eliz@gnu.org>
205 * .gdbinit (prowlims): Display the enabled_p flag of the row.
207 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>

276 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
278 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
279 * sysdep.c (list_system_processes)
280 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
281 Make it a stub in this case; otherwise the build might fail,
282 and this code hasn't been tested on such hosts anyway.
283 Problem reported by Nelson H. F. Beebe in
284 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
285 and analyzed by Jérémie Courrèges-Anglas in
286 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
288 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
290 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
291 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
292 (get_visually_first_element, move_it_vertically_backward): Ajust users.
293 * bidi.c (bidi_find_paragraph_start): Likewise.
294 * indent.c (vmotion): Likewise.
296 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
298 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
299 * filelock.c: Include <c-ctype.h>.
300 (MAX_LFINFO): New top-level constant.
301 (lock_info_type): Remove members pid, boot_time. Add members at,
302 dot, colon. Change user member to be the entire buffer, not a
303 pointer. This allows us to handle the case where a foreign
304 pid or boot time exceeds the local range. All uses changed.
305 (LINKS_MIGHT_NOT_WORK): New constant.
306 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
307 (defined_WINDOWSNT): Remove.
308 (MAKE_LOCK_NAME, file_in_lock_file_name):
309 Always use .#FILE (not .#-FILE) for the file lock,
310 even if it is a regular file.
311 (rename_lock_file): New function.
312 (create_lock_file): Use it.
313 (create_lock_file, read_lock_data):
314 Prefer a symbolic link for the lock file, falling back on a
315 regular file if symlinks don't work. Do not try to create
316 symlinks on MS-Windows, due to security hassles. Stick with
317 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
318 link, rename, unlink, mkstemp) when creating locks, as a GNUish
319 host may be using a Windowsish file system, and cannot use
320 MS-Windows-only system calls. Fall back on mktemp if mkstemp
321 doesn't work. Don't fail merely because of a symlink-contents
322 length limit in the current file system; fall back on regular
323 files. Increase the symlink contents length limit to 8 KiB, this
324 should be big enough for any real use and doesn't crunch the
326 (create_lock_file, lock_file_1, read_lock_data):
327 Simplify allocation of lock file buffers now that they fit in 8 KiB.
328 (lock_file_1): Return error number, not bool. All callers changed.
329 (ELOOP): New macro, if not already defined.
330 (read_lock_data): Return size of lock file contents, not Lisp object.
331 All callers changed. Handle a race condition if some other process
332 replaces a regular-file lock with a symlink lock or vice versa,
333 while we're trying to read the lock.
334 (current_lock_owner): Parse contents more carefully, to help avoid
335 confusing a regular-file lock with some other application's use
336 of the file. Check for lock file contents being too long, or
337 not parsing correctly.
338 (current_lock_owner, lock_file):
339 Allow foreign pid and boot times that exceed the local range.
340 (current_lock_owner, lock_if_free, lock_file):
341 Simplify allocation of lock file contents.
342 * w32.c (sys_rename_replace): New function, containing most of
343 the contents of the old sys_rename.
344 (sys_rename): Use it.
345 (fchmod): New dummy function.
346 * w32.h (sys_rename_replace, fchmod): New decls.
348 2013-03-05 Eli Zaretskii <eliz@gnu.org>
350 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
351 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
352 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
353 <dmantipov@yandex.ru>.
355 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
357 * composite.c (get_composition_id, fill_gstring_header):
358 Use make_uninit_vector where appropriate.
359 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
360 * xselect.c (clean_local_selection_data): Likewise.
362 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
364 Fix misuse of ImageMagick that caused core dump (Bug#13846).
365 * image.c (imagemagick_load_image): Calculate height and width
366 after flattening the image, not before.
368 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
370 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
371 * ftfont.c (ftfont_shape_by_flt): Likewise.
372 * w32uniscribe.c (uniscribe_shape): Likewise.
374 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
376 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
377 The old approach, which fell back on DIR/.#FILE.0 through
378 DIR/.#FILE.9, had race conditions that could not be easily fixed.
379 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
380 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
381 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
382 because the locking mechanism was never reliable in that case).
383 This patch fixes this and other bugs discovered by a code
384 inspection that was prompted by
385 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
386 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
387 to avoid interoperability problems between the MS-Windows and
388 non-MS-Windows implementations. MS-Windows and non-MS-Windows
389 instances of Emacs now ignore each others' locks.
390 * filelock.c (defined_WINDOWSNT): New constant.
391 (MAKE_LOCK_NAME, fill_in_lock_file_name):
392 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
393 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
394 regular files on MS-Windows hosts.
395 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
396 Use SAFE_ALLOCA to avoid problems with long file names.
397 (MAX_LFINFO): Now a local constant, not a global macro.
398 (IS_LOCK_FILE): Remove.
399 (lock_file_1): Don't inspect errno if symlink call succeeds;
401 (lock_file): Document that this function can return if lock
403 (lock_file): Don't access freed storage.
405 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
407 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
409 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
411 * textprop.c: Use bool for booleans.
412 (validate_interval_range, Fadd_text_properties)
413 (Fremove_text_properties): Prefer bool to int when either works.
415 2013-03-02 Eli Zaretskii <eliz@gnu.org>
417 * textprop.c (Fadd_text_properties, Fremove_text_properties):
418 If the interval tree changes as a side effect of calling
419 modify_region, re-do processing starting from the call to
420 validate_interval_range. (Bug#13743)
422 2013-02-28 Eli Zaretskii <eliz@gnu.org>
424 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
427 2013-02-27 Eli Zaretskii <eliz@gnu.org>
429 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
430 _SH_DENYRW flag, instead of emacs_open, to deny any other process
431 access to the lock file until it is written and closed.
434 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
436 * callint.c (Qcall_interactively):
437 * macros.c (Qexecute_kbd_macro):
440 2013-02-26 Bastien Guerry <bzg@gnu.org>
442 * window.c (Frecenter): Tiny docstring enhancement.
444 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
446 Minor textprop integer cleanup.
447 * intervals.h, textprop.c (add_text_properties_from_list):
448 Return void, not int, since nobody uses the return value.
449 * textprop.c (validate_plist, add_properties, remove_properties)
450 (Fadd_text_properties):
451 Don't assume list length fits in int.
452 (interval_has_all_properties, interval_has_some_properties)
453 (interval_has_some_properties_list, add_properties, remove_properties)
454 (Fadd_text_properties, Fremove_text_properties)
455 (Fremove_list_of_text_properties, text_property_stickiness):
456 Use bool for booleans.
457 (Fadd_text_properties, Fremove_text_properties):
458 (Fremove_list_of_text_properties):
459 Reindent do-while as per GNU style.
461 2013-02-25 Eli Zaretskii <eliz@gnu.org>
463 Implement CLASH_DETECTION for MS-Windows.
465 * filelock.c [WINDOWSNT]: Include w32.h.
466 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
467 function of that name. Up-case the macro arguments.
468 (IS_LOCK_FILE): New macro.
469 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
470 (create_lock_file): New function, with body extracted from
472 [WINDOWSNT]: Implement lock files by writing a regular file with
473 the lock information as its contents.
474 (read_lock_data): New function, on Posix platforms just calls
476 [WINDOWSNT]: Read the lock info from the file.
477 (current_lock_owner): Call read_lock_data instead of calling
478 emacs_readlinkat directly.
479 (lock_file) [WINDOWSNT]: Run the file name through
482 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
483 just check if the process by that PID exists.
485 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
486 also present, as doing so will fail to error out if the file
489 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
491 * textprop.c (Fadd_text_properties, Fremove_text_properties)
492 (Fremove_list_of_text_properties): Skip all of the intervals in
493 the region between START and END that already have resp. don't
494 have the requested properties, not just the first one.

496 properties. (Bug#13743)
498 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

508 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
509 (START_FILES): Remove. All uses removed.
510 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.

528 so simplify-away some unnecessary exactness.
529 (POINTER): Remove; all uses removed.
530 (data_space_start): Now char *, to avoid casts.
531 (exceeds_lisp_ptr): New function, replacing the old

553 Assume C89 or better.
554 * ralloc.c (SIZE, POINTER, NIL):
555 * vm-limit.c (POINTER):
556 Remove, replacing all uses with C89 equivalents. These old
557 symbols were present only for porting to pre-C89 platforms.
559 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
561 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
562 This avoids warning messages reported as part of Bug#13546.
564 2013-02-21 Ken Brown <kbrown@cornell.edu>
566 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

577 2013-02-19 Daniel Colascione <dancol@dancol.org>
579 * sheap.c (report_sheap_usage): Use message, not message1, so
580 that we don't try to create a buffer while we're in the middle
581 of dumping Emacs. Explain why.
583 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
585 * search.c (find_newline): Return byte position in bytepos.

680 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
682 Fix AIX port (Bug#13650).
683 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
684 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
685 was #undeffed earlier, so it cannot be used as a macro here.
686 Use the constant and not the macro.
688 2013-02-15 Eli Zaretskii <eliz@gnu.org>
690 * w32proc.c (new_child): If no vacant slots are found in
691 child_procs[], make another pass looking for slots whose process
692 has exited or died. (Bug#13546)

695 MAXDESC, set errno to EMFILE.
696 (_sys_read_ahead): Update cp->status when failing to read serial
697 communications input, so that the status doesn't stay at
698 STATUS_READ_IN_PROGRESS. (Bug#13546)
700 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
702 * gtkutil.c (tb_size_cb): New function.
703 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

722 2013-02-13 Glenn Morris <rgm@gnu.org>
724 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
726 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
728 Improve AIX port some more (Bug#13650).
729 With this, it should be as good as it was in 23.3, though it's
730 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
731 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
732 * unexaix.c (start_of_text): Remove.
733 (_data, _text): Declare as char[], not int, as AIX manual suggests.
734 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
735 (orig_load_scnptr, orig_data_scnptr):
736 Now off_t, not long, since they are file offsets.
737 (make_hdr): Use _data, not start_of_data ().
738 This is the key part of the fix.
739 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
740 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
742 * pre-crt0.c (data_start): Initialize to 1.
743 This ports to compilers that optimize the external declaration
744 'int x = 0;' as if it were 'int x;' to shrink the executable.
746 Improve AIX port (Bug#13650).
747 This doesn't fix the bug, but it makes progress: Emacs builds now.
748 * unexaix.c: Include inttypes.h, stdarg.h.
749 (report_error, report_error_1): Mark as _Noreturn.
750 (report_error): Don't report the wrong errno.
751 (report_error_1): Now varargs. All callers changed.
752 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
753 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
754 (write_ptr): Use %p to print address rather than %lx and a cast
755 to unsigned long. Grow buffer a bit, to be safer.
757 2013-02-13 Eli Zaretskii <eliz@gnu.org>
759 * bidi.c (bidi_resolve_neutral): After finding the next
760 non-neutral character, accept NEUTRAL_ON type as well, because
761 directional control characters, such as LRE and RLE, have their
762 type converted to that by bidi_resolve_weak. This avoids aborts
763 when LRE/RLE follows a run of neutrals.
764 (bidi_move_to_visually_next): Assert that return value of
765 bidi_peek_at_next_level is non-negative. Negative values will
768 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
770 Minor getenv-related fixes.
771 * callproc.c (Fcall_process_region) [!DOS_NT]:

773 * callproc.c (init_callproc):
774 * dispnew.c (init_display):

776 Omit unnecessary cast of getenv or egetenv.
778 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
780 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
783 2013-02-12 Eli Zaretskii <eliz@gnu.org>
785 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
787 (display_line): Set w->region_showing to the value of
788 it->region_beg_charpos, not to -1. This fixes redisplay
789 optimization when cursor is moved up after M->. (Bug#13623)
791 (try_scrolling): Scroll text up more if point is too close to ZV
792 and inside the scroll margin. This makes sure point is moved
793 outside the scroll margin in these cases.
795 * window.h (struct window): region_showing can no longer be
798 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
800 Tune by using memchr and memrchr.
801 * doc.c (Fsnarf_documentation):
802 * fileio.c (Fsubstitute_in_file_name):
803 * search.c (find_newline, scan_newline):
804 * xdisp.c (pos_visible_p, display_count_lines):
805 Use memchr and memrchr rather than scanning byte-by-byte.
806 * search.c (find_newline): Rename from scan_buffer.
807 Omit first arg TARGET, as it's always '\n'. All callers changed.
809 Clean up read_key_sequence a tiny bit more.
810 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
811 (read_key_sequence): Remove unused locals.
813 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
815 Clean up read_key_sequence a bit; reread active keymaps after first event.
816 * keyboard.c (read_char, read_char_x_menu_prompt)
817 (read_char_minibuf_menu_prompt):
818 Replace nmaps+maps with a single `map' arg.
819 (follow_key): Operate on a single map.
820 (active_maps): New function.
821 (test_undefined): Also return true for nil bindings.
822 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
823 a single (composed) keymap. Remember `first_event' to choose the right
824 set of active keymaps. Recompute the set of keymaps after receiving
825 the first event. Remove GOBBLE_FIRST_EVENT.
826 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
827 * keyboard.h (read_char): Update declaration.
828 * lread.c (read_filtered_event): Adjust call to read_char.
830 2013-02-11 Eli Zaretskii <eliz@gnu.org>
832 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
833 Don't use the limitation on backwards movement when lines are truncated
834 in the window. (Bug#13675)
836 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
838 * marker.c (set_marker_internal): If desired position is passed
839 as a marker, avoid call to buf_charpos_to_bytepos.
840 * window.c (Fset_window_point): Omit redundant type checking.
841 (Fset_window_start): Likewise. Format comment.
842 (window_scroll_pixel_based): Use set_marker_restricted_both
843 with character and byte positions obtained from an iterator.
844 (Fset_window_configuration): Use set_marker_restricted_both.
845 * xdisp.c (message_dolog): Likewise.
847 2013-02-10 Eli Zaretskii <eliz@gnu.org>
849 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
850 When text lines are longer than window's screen lines, don't move back
851 too far. This speeds up some redisplay operations. (Bug#13675)
853 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
855 * syntax.c (scan_sexps_forward): Fix byte position calculation
856 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.

860 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
863 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
865 Minor hashing refactoring.
866 * fns.c (SXHASH_REDUCE): Move to lisp.h.
867 (sxhash_float): Return EMACS_UINT, for consistency with the other
869 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
870 non-static inline function and therefore can't use static vars.
871 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
872 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
873 with the other hash functions.
875 2013-02-09 Eli Zaretskii <eliz@gnu.org>
877 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
878 XXXXXX part of the temporary file pattern is not downcased even
879 when w32-downcase-file-names is non-nil. (Bug#13661)
881 * xdisp.c (decode_mode_spec): Remove handling of %t.
883 * msdos.c (careadlinkatcwd): Remove.
885 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
887 * lread.c (skip_dyn_bytes): New function (bug#12598).

956 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
957 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
958 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
959 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
960 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
961 (syms_of_nsterm): Add ns-use-native-fullscreen.
963 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
965 * fileio.c (Qchoose_write_coding_system): Now static.
967 2013-02-04 Eli Zaretskii <eliz@gnu.org>
969 * xdisp.c (window_buffer_changed): region_showing can be negative,
970 which still means region is being displayed.
971 (redisplay_internal): Resurrect code that forced redisplay of the
972 whole window when showing region and the mark has changed.
973 Record the new mark position to allow redisplay optimizations.
974 (display_line): If it->region_beg_charpos is non-zero, set the
975 window's region_showing member to -1. (Bug#13623) (Bug#13626)
977 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
978 not bitfield of 1 bit.
980 2013-02-03 Daniel Colascione <dancol@dancol.org>
982 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
983 daemon mode works on cygw32 when Emacs is installed and not just
986 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
988 Avoid file time stamp bug on MS-Windows (Bug#13149).
989 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
990 as FAT32 doesn't update time stamps when truncating them.
991 Also, check that a file time stamp is not a multiple of 100 ns;
992 this should catch all instances of the problem on MS-Windows,
993 as its native file system resolution is 100 ns or worse, and
994 checking for a non-multiple of 100 ns should impose only a small
995 overhead on systems with ns resolution.
997 2013-02-02 Eli Zaretskii <eliz@gnu.org>
999 Avoid encoding file names on MS-Windows when they need to be run
1000 through dostounix_filename.
1001 * w32.c (normalize_filename): Accept an additional argument
1002 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1003 downcase it even if w32-downcase-file-names is non-nil.
1004 (dostounix_filename): Accept an additional argument MULTIBYTE and
1005 pass it to normalize_filename.
1006 (emacs_root_dir): Adjust.
1008 * msdos.h (dostounix_filename): Adjust prototype.
1010 * w32.h (dostounix_filename): Adjust prototype.
1012 * msdos.c (dostounix_filename): Accept an additional argument and
1014 (init_environment): Adjust callers of dostounix_filename.
1016 * fileio.c (Ffile_name_directory, file_name_as_directory)
1017 (directory_file_name, Fexpand_file_name)
1018 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1020 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1022 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1023 variables, as egetenv is case-insensitive for DOS_NT.
1025 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1026 with an encoded file name.
1028 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1029 Adjust calls to dostounix_filename.
1031 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1033 * unexw32.c (unexec): Adjust call to dostounix_filename.
1035 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1037 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1040 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1043 * callproc.c (Fcall_process): Make sure program name in PATH and
1044 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1045 is passed to exec/spawnve, which fails unless the file-name
1048 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1049 even if w32-quote-process-args is nil.
1051 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1053 Fix timestamp bug when write-region appends nothing (Bug#13149).
1054 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1055 the file's time stamp doesn't change if Emacs happens to write nothing
1056 to the file, and on a buggy file system this could cause Emacs to
1057 incorrectly infer that the file system doesn't have the bug.
1058 Avoid this problem by inhibiting the inference in this case.
1060 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1062 * window.h (struct window): Convert base_line_number, base_line_pos
1063 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1064 Convert region_showing member from Lisp_Object to bitfield.
1065 Remove sequence_number member. Adjust comments.
1066 * window.c (sequence_number): Remove.
1067 (make_window): Initialize column_number_displayed.
1068 * print.c (print_object): Follow the printed representation of
1069 frames and print window pointer to distinguish between windows.
1070 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1071 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1072 (wset_column_number_displayed, wset_region_showing): Remove.
1073 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1074 (try_scrolling, try_cursor_movement, redisplay_window)
1075 (try_window_reusing_current_matrix, try_window_id, display_line)
1076 (display_mode_lines, decode_mode_spec): Adjust users.
1077 * .gdbinit (pwinx): Do not print sequence_number.
1079 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1081 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1082 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1083 * dired.c: Include <fcntl.h>.
1084 (open_directory): New function, which uses open and fdopendir
1085 rather than opendir. DOS_NT platforms still use opendir, though.
1086 (directory_files_internal, file_name_completion): Use it.
1087 (file_attributes): New function, with most of the old Ffile_attributes.
1088 (directory_files_internal, Ffile_attributes): Use it.
1089 (file_attributes, file_name_completion_stat): First arg is now fd,
1090 not dir name. All uses changed. Use fstatat rather than lstat +
1092 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1093 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1094 (emacs_readlinkat): New function, with much of the old
1095 Ffile_symlink_p, but with an fd argument for speed.
1096 It uses readlinkat rather than careadlinkatcwd, so that it
1097 need not assume the working directory.
1098 (Ffile_symlink_p): Use it.
1099 * filelock.c (current_lock_owner): Use emacs_readlinkat
1100 rather than emacs_readlink.
1101 * lisp.h (emacs_readlinkat): New decl.
1102 (READLINK_BUFSIZE, emacs_readlink): Remove.
1103 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1104 (emacs_norealloc_allocator, emacs_readlink): Remove.
1105 This stuff is moved to fileio.c.
1106 * w32.c (fstatat, readlinkat): New functions.
1107 (careadlinkat): Don't check that fd == AT_FDCWD.
1108 (careadlinkatcwd): Remove; no longer needed.
1110 2013-01-31 Glenn Morris <rgm@gnu.org>
1112 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1113 (Fwrite_region): Update for new choose_write_coding_system args.
1114 Move the last piece of choose_write_coding_system here. (Bug#13522)
1115 (syms_of_fileio): Add choose-write-coding-system.
1117 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1119 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1120 (sys_close): Zero out the flags for the file descriptor before
1121 closing it. (Bug#13546)
1123 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1124 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1125 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1128 * w32.c (w32_get_long_filename, init_environment, readlink):
1129 Support file names encoded in DBCS codepages.
1130 (readlink): Use the current file-name-coding-system, not the ANSI
1131 codepage, to decode and handle targets of symlinks.
1133 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1135 * w32.c (opendir): Now accepts a 'const char *'.
1137 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1139 Remove obsolete redisplay code. See the discussion at
1140 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1141 * dispnew.c (preemption_period, preemption_next_check): Remove.
1142 (Vredisplay_preemption_period): Likewise.
1143 (update_frame, update_single_window, update_window, update_frame_1):
1144 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1145 used, following the 2012-06-22 change.
1147 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1149 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1151 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1153 * font.c (num_fonts): Remove the leftover from old
1154 debugging code. Adjust comment style here and there.
1155 * insdel.c (insert_1): Remove.
1156 * lisp.h (insert_1): Remove prototype.
1157 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1159 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1161 * w32.c (max_filename_mbslen): New function.
1162 (normalize_filename, readdir): Use it to detect locales where ANSI
1163 encoding of file names uses a double-byte character set (DBCS).
1164 If a DBCS encoding is used, advance by characters using
1165 CharNextExA, instead of incrementing a 'char *' pointer.
1166 Use _mbslwr instead of _strlwr. (Bug#13515)
1168 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1169 request of memory reservation to 1.7GB. (Bug#13065)
1171 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1173 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1174 at check_extra_latin label. (Bug#13505)
1176 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1178 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1179 Avoid redundant calls to strlen.
1181 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1183 Drop async_visible and async_iconified fields of struct frame.
1184 This is possible because async input is gone; for details, see
1185 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1186 * frame.h (struct frame): Remove async_visible and async_iconified
1187 members, convert garbaged to unsigned bitfield. Adjust comments.
1188 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1189 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1190 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1191 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1192 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1194 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1195 properly. Likewise for obscured.
1197 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1200 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1202 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1204 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1205 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1207 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1209 * xdisp.c (message2, message2_nolog): Remove functions.
1210 (message3, message3_nolog): Extract nbytes and multibyteness directly
1211 from the string. Change all callers.
1212 (message3_nolog): Don't set message_enable_multibyte since set_message
1213 will reset it anyway.
1214 (message1, message1_nolog): Use message3.
1215 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1216 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1217 (set_message): Drop all but the second arg, which has to be a string.
1218 (set_message_1): Simplify now that we know that a1 is NULL and the
1219 second arg is a string.
1220 * frame.h (struct frame): Remove `message_buf' field.
1221 Use glyphs_initialized_p instead.
1222 (FRAME_MESSAGE_BUF): Remove macro.
1223 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1224 * lisp.h (message2, message2_nolog): Remove declarations.
1225 (message3, message3_nolog): Update declarations.
1226 * keyboard.c (read_char_minibuf_menu_text)
1227 (read_char_minibuf_menu_width): Remove vars.
1228 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1229 to correctly handle multibyte strings.
1230 * frame.c (delete_frame): Don't free message_buf any more.
1231 * editfns.c (message_text, message_length): Remove vars.
1232 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1233 * fileio.c (auto_save_error): Use message3 instead of message2.
1234 * dispnew.c (adjust_frame_message_buffer): Remove function.
1236 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1238 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1239 real estate used for the tool bar and the menu bar.
1241 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1243 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1244 hidden buffer is prepared to modification (Bug#13164).
1246 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1248 * window.h (struct window): Change window_end_valid member from
1249 Lisp_Object to a bitfield. Adjust comments.
1250 (wset_window_end_valid): Remove.
1251 * window.c (adjust_window_count): Clear window_end_valid.
1252 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1253 (Fwindow_line_height, set_window_buffer, Frecenter)
1254 (Fsplit_window_internal, Fdelete_other_windows_internal)
1255 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1256 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1257 * xdisp.c (check_window_end, reconsider_clip_changes)
1258 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1259 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1260 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1262 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1264 * xdisp.c (mark_window_display_accurate): Simplify the loop
1265 assuming that the only one of vchild, hchild or buffer window
1266 slots is non-nil. Call mark_window_display_accurate_1 for
1267 the leaf windows only.
1268 (mark_window_display_accurate_1): Always assume leaf window.
1271 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1273 * emacs.c (Qkill_emacs_hook): Now static.
1275 * fileio.c (Finsert_file_contents): Simplify.
1276 Remove unnecessary assignments and tests.
1278 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1280 * w32.c (acl_set_file): Don't test for errors unless
1281 set_file_security returns FALSE. Avoids spurious errors when
1284 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1286 * fileio.c (Finsert_file_contents): Revert code introduced at
1287 2013-01-18 in favor of the simpler and generally better fix.
1288 Save stack space by removing 'buffer' and reusing 'read_buf'
1291 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1293 * lisp.h (eabs): Define unconditionally (Bug#13419).
1294 The old "#if !defined (eabs)" was an unnecessary revenant of back
1295 when this macro was called "abs". Document 'eabs' better.
1297 2013-01-19 Glenn Morris <rgm@gnu.org>
1299 * fns.c (Frandom): Doc fix.
1301 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1303 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1304 segfault when there are lots of overlays.
1306 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1307 when there are lots of overlays.
1308 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1309 for the details and a way to reproduce.
1311 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1313 * fileio.c: Use O_APPEND to append.
1314 This corresponds better to the natural interpretation of "append",
1315 and avoids the need to open the output file twice, or to invoke
1316 lseek when APPEND is neither nil nor a number.
1317 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1318 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1319 file possibly twice, and lseeking to its end; this avoids the
1320 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1321 at the same time: the combination is never needed and apparently
1322 it doesn't work with DOS_NT.
1324 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1325 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1327 Allow floating-point file offsets.
1328 Problem reported by Vitalie Spinu in
1329 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1330 * fileio.c (emacs_lseek): Remove.
1331 (file_offset): New function.
1332 (Finsert_file_contents, Fwrite_region): Use it.
1334 2013-01-19 Chong Yidong <cyd@gnu.org>
1336 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1337 aborting on Fsignal (Bug#13289).
1339 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1341 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1342 set_file_security as failure due to insufficient privileges.
1343 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1344 (fstat): Return owner and group like 'stat' and 'lstat' do.
1346 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1348 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1349 The bug was observed on Ubuntu operating inside a virtual machine,
1350 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1351 The workaround introduces a race condition on non-buggy hosts,
1352 but it's an unlikely race and anyway there's a nearly identical
1353 nearby race that can't be fixed.
1354 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1356 (Fwrite_region): Test for file system time stamp bug.
1357 (init_fileio): New function.
1358 * lisp.h (init_fileio): Declare it.
1359 * emacs.c (main): Call it.
1361 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1362 and make it more consistent with other stat-failure diagnostics.
1364 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1366 Fix crash when inserting data from non-regular files.
1367 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1368 for the error description produced by valgrind.
1369 * fileio.c (read_non_regular): Rename to read_contents.
1370 Free Lisp_Save_Value object used to pass parameters.
1371 (read_non_regular_quit): Rename to read_contents_quit.
1372 (Finsert_file_contents): Redesign internal file reading loop to adjust
1373 gap and end positions after each read and so help make_gap to work
1374 properly. Do not signal an I/O error too early and so do not leave
1375 not yet decoded characters in a buffer, which was the reason of
1376 redisplay crash. Use list2 to build return value. Adjust comments.
1378 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1380 Close a race when statting and reading files (Bug#13149).
1381 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1382 This avoids a race if the file is renamed between stat and open.
1383 This race is not the problem originally noted in Bug#13149;
1384 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1386 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1388 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
1389 objects, related functions and macros.
1390 (make_save_value): Adjust prototype.
1391 (make_save_pointer): New prototype.
1392 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
1393 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1394 * alloc.c (format_save_value): Rename to make_save_value.
1395 (make_save_pointer): New function.
1396 (record_xmalloc): Use make_save_pointer.
1397 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1398 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1399 Change users of make_save_value to make_save_pointer.
1400 Likewise for format_save_value and make_save_value.

1486 because we do not allocate extra memory any more. Add eassert.
1487 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1488 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1502 Fix SIGDANGER handlers, for AIX (Bug#13408).
1503 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1574 switches from 'signal' to 'pthread_sigmask', which is safer in
1575 multithreaded applications.
1576 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1577 which has already arranged for that.
1578 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

1598 left-margin-width, right-margin-width, left-fringe-width,
1599 right-fringe-width, scroll-bar-width and buffer-display-count.
1600 Use Qstringp for default-directory, buffer-file-name,
1601 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1602 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

1688 * term.c (tty_ins_del_lines):
1689 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1690 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1692 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1694 * w32.c (unsetenv): Set up the string passed to _putenv
1696 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html

1703 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1705 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.

1718 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1720 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1721 (xg_update_menubar): Update title only if

1723 (xg_update_submenu): Skip tearoff only if
1724 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1725 (xg_initialize): Initialize xg_detached_menus only if
1726 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1728 * xterm.h (struct x_output): Surround handlebox_widget with
1729 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1730 toolbar_in_hbox is bool.
1732 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1734 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.

1766 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1768 * fileio.c (file_name_as_directory, directory_file_name):
1769 Accept an additional argument MULTIBYTE to indicate whether the input C
1770 came from a multibyte or a unibyte Lisp string; all callers
1771 adjusted. Don't assume the input string is always multibyte.
1773 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1774 don't ENCODE_FILE them, and return a unibyte string if the input
1776 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1777 don't assume the input strings will always be multibyte. If the
1778 input strings are multibyte, decode strings obtained from C
1781 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1783 * lisp.h (toplevel): Add two notices to the comment about
1784 defining a new Lisp data type.

1792 * keyboard.c (record_asynch_buffer_change): Initialize an event
1793 only if it's really needed.
1794 * frame.h (enum output_method): Remove output_mac member since
1795 it's a leftover from the deleted code.
1796 * frame.c (Fframep): Adjust user here ...
1797 * terminal.c (Fterminal_live_p): ... and here.
1798 * coding.c (Qmac): Now here because it's only used to denote
1799 end-of-line encoding type.
1800 (syms_of_coding): DEFSYM it.
1801 * frame.h (Qmac): Remove duplicated declaration.
1803 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1805 * window.c (select_window_1): Now static, since it's used only here.
1807 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1809 * window.c (window_body_cols): Subtract display margins from the
1810 window body width on TTYs as well. See
1811 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1812 for the original report.
1814 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1816 * xdisp.c (redisplay_window): Remove inner local variable
1817 because the outer shadowed one has the same meaning.
1818 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1820 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1821 (xg_create_tool_bar): Adjust users.
1823 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1825 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1826 * buffer.c (Fget_buffer_create): Use it to set compact field of
1827 struct buffer_text to avoid accessing an uninitialized value
1828 when compact_buffer is called for the first time.
1829 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1830 (Fset_buffer_modified_p): Use buffer_window_count to check
1831 whether the buffer is displayed in some window.

1836 * w32.c (acl_set_file): If setting the file security descriptor
1837 fails, and the new DACL is identical to the existing one, silently

1839 own files without having the necessary privileges for setting
1840 security descriptors.
1842 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1844 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1845 after WaitForSingleObject returns normally. This expedites reader
1846 thread shutdown when delete_child triggers it.
1847 (reap_subprocess): More accurate commentary for why we call
1848 delete_child only when cp->fd is negative.
1850 * w32.c (sys_close): Do not call delete_child on a subprocess
1851 whose handle is not yet closed. Instead, set its file descriptor
1852 to a negative value, so that reap_subprocess will call
1853 delete_child on that subprocess when its SIGCHLD arrives.
1854 This avoids closing handles used for communications between sys_select
1855 and reader_thread, which doesn't give sys_select a chance to
1856 notice that the process exited and invoke the SIGCHLD handler for
1859 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>

1877 * fileio.c (Finsert_file_contents): Doc fix.
1879 * w32proc.c (new_child, delete_child, find_child_pid): For a
1880 subprocess, consider its slot being in use as long as its process
1881 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1882 slot when a new process is started immediately after killing
1883 another one, without waiting enough time for the first process to
1884 be reaped and resources allocated for it be orderly freed.
1886 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1888 2012-12-21 Chong Yidong <cyd@gnu.org>

1899 Remove now unused argument FNAME; all callers changed.
1900 (get_file_owner_and_group): Remove now unused argument FNAME; all
1903 2012-12-21 Chong Yidong <cyd@gnu.org>
1905 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1906 error for invalid chars, don't check for a nil return value.

1933 proper value of frame-local variables (bug#13225).
1935 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1937 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1938 Rename 4th argument since it may be buffer or string. Adjust comment.
1939 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1941 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1943 * coding.c (Fdetect_coding_region): Do not check start and end with
1944 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1945 (code_convert_region): Likewise.
1947 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1949 * w32.c (acl_get_file, acl_set_file): Run the file name through

1963 propagate redisplay's scrolling (if any) to the right window.
1964 (redisplay_internal): Use ensure_selected_frame.
1965 (display_mode_lines): Complete last fix.
1966 * window.c (select_window_1): New func, extracted from select_window.
1967 (select_window): Use it.
1968 * window.h (select_window_1): Declare.

1994 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1996 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1997 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1998 for some of that bug's symptoms can now cause Emacs to abort.
1999 Remove the workaround.
2000 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2001 The bug that caused SIGCHLD to get lost has been fixed, and the
2002 workaround for it can now cause Emacs to abort.
2004 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2006 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2007 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in

2044 * lisp.h (internal_delete_file): Adjust prototype.
2046 * callproc.c (Fcall_process): Don't overwrite infile with result
2048 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2049 asynchronous subprocess, record the name of the input file name,
2051 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2052 delete the file, record it as pending deletion when the subprocess
2055 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2057 * editfns.c [HAVE_PWD_H]: Include grp.h.

2063 Fix permissions bugs with setgid directories etc. (Bug#13125)
2064 * dired.c (Ffile_attributes): Return t as the 9th attribute,

2075 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2077 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2078 try to get accurate owner and group information from NT file
2079 security APIs. This is to make most callers of 'stat' and
2080 'lstat', which don't need that information, much faster.
2082 * dired.c (Ffile_attributes) [WINDOWSNT]:
2083 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2084 owner and group information from 'lstat'.
2086 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2088 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2089 as that confuses set-auto-coding, so insist on the head-read

2094 (init_iterator): Hoist assignment out of if-expression.
2095 (markpos_of_region): Callers now test for sign, not for -1.

2114 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2115 files, fixing a regression from 24.2.
2116 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2118 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2120 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2121 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2122 Remove unnecessary S_ISLNK test, as (contra the comments) this
2123 function can't copy symlinks. Improve quality of error message
2124 when attempting to copy files that are neither regular files nor

2135 2012-12-12 Daniel Colascione <dancol@dancol.org>
2137 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2138 the dumped Emacs is not a sparse file, greatly improving Cygwin
2139 "make bootstrap" performance.
2141 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2143 * inotify.c (inotify_callback): Generate an Emacs event for every
2144 incoming inotify event.
2146 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2148 * xdisp.c (handle_face_prop): Fix logic of computing
2149 it->start_of_box_run_p.
2150 (append_space_for_newline): If the glyph row is R2L, reset the
2151 iterator's end_of_box_run_p flag before prepending the space glyph.
2152 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2153 iterator's start_of_box_run_p flag before prepending the stretch.

2155 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2156 left_box_line_p and right_box_line_p flags of the glyph for R2L
2157 glyph rows. (Bug#13011)

2207 (hinst): Remove unneeded extern declaration.
2208 (_start): Remove initialization of above variables; remove

2353 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2355 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
2356 * alloc.c (xputenv): New function.
2357 * dbusbind.c (Fdbus_init_bus):
2359 * xterm.c (x_term_init):
2360 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
2361 * editfns.c (initial_tz): Move static var decl up.
2362 (tzvalbuf_in_environ): New static var.
2363 (init_editfns): Initialize these two static vars.
2364 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
2365 Save old TZ value on stack, if it's small.
2366 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
2367 instead, use xputenv+unsetenv to set and restore TZ.
2368 (environbuf): Remove static var. All uses removed.
2369 (Fset_time_zone_rule): Do not save TZ and environ;
2370 no longer needed here.
2371 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2372 Move to inside set_time_zone_rule; they don't need file scope any more.
2373 (set_time_zone_rule): Maintain the TZ=value string separately.
2374 (syms_of_editfns): Don't initialize initial_tz;
2375 init_editfns now does it.
2376 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2377 * lisp.h (xputenv): New decl.
2379 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2381 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2383 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2385 * w32.c (unsetenv, sys_putenv): New functions.
2387 2012-12-08 Chong Yidong <cyd@gnu.org>
2389 * editfns.c (Finsert_char): Make the error message more
2390 informative (Bug#12992).
2392 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2394 Simplify get_lim_data.
2395 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2396 Remove USG and vlimit methods; no longer used these days.
2397 Add #error catchall just in case.
2399 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2400 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2401 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2402 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2403 (deleted_pid_list, Fdelete_process, create_process)
2404 (record_child_status_change, handle_child_signal, deliver_child_signal)
2405 (init_process_emacs, syms_of_process):
2406 Assume SIGCHLD is defined.
2407 (parse_signal): Remove. All uses removed.
2408 (abbr_to_signal): New static function.
2409 (Fsignal_process): Use it to convert signal names to ints.
2410 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2411 kill (getpgrp (), ...).
2412 (emacs_sigaction_init): Assume SIGCHLD is defined.
2413 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2414 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2415 * syssignal.h (EMACS_KILLPG): Remove.
2416 All uses replaced by 'kill' with a negative pid.
2417 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2418 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2420 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2422 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2423 This will cause a production Emacs to dump core instead of
2426 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2428 * frame.c (make_frame): Do not set window's buffer to t.
2429 * window.c (Fsplit_window_internal): Likewise. Previously it was
2430 used to indicate that the window is being set up. Now we use
2431 set_window_buffer for all new windows, so the condition in ...
2432 (Fset_window_buffer): ... is always true and can be removed.
2434 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2436 Convenient macro to check whether the buffer is hidden.
2437 * buffer.h (BUFFER_HIDDEN_P): New macro.
2438 * frame.c (make_frame): Use it. Adjust comment.
2439 * buffer.c (candidate_buffer): New function.
2440 (Fother_buffer, other_buffer_safely): Use it.
2442 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2444 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2445 if the child process is still running. Instead, exit the wait
2446 loop and return zero. (Bug#13086)
2448 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2450 * frame.h (x_char_width, x_char_height): Remove prototypes.
2451 * w32term.h (x_char_width, x_char_height): Likewise.
2452 * xfns.c (x_char_width, x_char_height): Remove.
2453 * w32fns.c (x_char_width, x_char_height): Likewise.
2454 * nsfns.c (x_char_width, x_char_height): Likewise.
2455 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
2457 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
2458 * keyboard.c (command_loop_1): Remove prototype.

2461 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2463 Fix a recently-introduced delete-process race condition.
2464 * callproc.c, process.h (record_kill_process):
2465 New function, containing part of the old call_process_kill.
2466 (call_process_kill): Use it.
2467 This does not change call_process_kill's behavior.
2468 * process.c (Fdelete_process): Use record_kill_process to fix a
2469 race condition that could cause Emacs to lose track of a child.
2471 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2473 Avoid code duplication between prev_frame and next_frame.
2474 * frame.c (candidate_frame): New function. Add comment.
2475 (prev_frame, next_frame): Use it. Adjust comment.
2477 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2479 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2480 fails, signal an error instead of continuing with an empty
2482 Encode expanded temp file pattern before passing it to mkstemp or
2485 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2486 Encode the file name before passing it to dostounix_filename, in
2487 case it will downcase it (under w32-downcase-file-names).
2490 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2492 Minor call-process cleanups.
2493 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2494 at the same time as other platforms, to simplify analysis.
2495 No need for fd0_volatile since we have synch_process_fd.
2496 Avoid needless emacs_close; arg is always negative.
2498 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2500 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2503 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2505 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2506 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2507 and mouse_face_hidden members to a bitfields.
2508 * frame.h (struct frame): Remove set-but-not-used space_width member.
2509 (FRAME_SPACE_WIDTH): Remove.
2510 * nsterm.m, w32term.c, xterm.c: Adjust users.
2511 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2512 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2513 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2514 members to a bitfields.
2516 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2518 Don't let call-process be a zombie factory (Bug#12980).
2519 Fixing this bug required some cleanup of the signal-handling code.
2520 As a side effect, this change also fixes a longstanding rare race
2521 condition whereby Emacs could mistakenly kill unrelated processes,
2522 and it fixes a bug where a second C-g does not kill a recalcitrant
2523 synchronous process in GNU/Linux and similar platforms.
2524 The patch should also fix the last vestiges of Bug#9488,
2525 a bug which has mostly been fixed on the trunk by other changes.
2526 * callproc.c, process.h (synch_process_alive, synch_process_death)
2527 (synch_process_termsig, sync_process_retcode):
2528 Remove. All uses removed, to simplify analysis and so that
2529 less consing is done inside critical sections.
2530 * callproc.c (call_process_exited): Remove. All uses replaced
2531 with !synch_process_pid.
2532 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2533 These take the role of what used to be in unwind-protect arg.
2535 (block_child_signal, unblock_child_signal):
2536 New functions, to avoid races that could kill innocent-victim processes.
2537 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2538 (call_process_kill): Record killed processes as deleted, so that
2539 zombies do not clutter up the system. Do this inside a critical
2540 section, to avoid a race that would allow the clutter.
2541 (call_process_cleanup): Fix code so that the second C-g works again
2542 on common platforms such as GNU/Linux.
2543 (Fcall_process): Create the child process in a critical section,
2544 to fix a race condition. If creating an asynchronous process,
2545 record it as deleted so that zombies do not clutter up the system.
2546 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2547 light of these changes. Omit unnecessary call to emacs_close
2548 before failure, as the unwind-protect code does that.
2549 * callproc.c (call_process_cleanup):
2550 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2551 * process.c (record_deleted_pid): New function, containing
2552 code refactored out of Fdelete_process.
2553 (Fdelete_process): Use it.
2554 (process_status_retrieved): Remove. All callers changed to use
2555 child_status_change.
2556 (record_child_status_change): Remove, folding its contents into ...
2557 (handle_child_signal): ... this signal handler. Now, this
2558 function is purely a handler for SIGCHLD, and is not called after
2559 a synchronous waitpid returns; the synchronous code is moved to
2560 wait_for_termination. There is no need to worry about reaping
2561 more than one child now.
2562 * sysdep.c (get_child_status, child_status_changed): New functions.
2563 (wait_for_termination): Now takes int * status and bool
2564 interruptible arguments, too. Do not record child status change;
2565 that's now the caller's responsibility. All callers changed.
2566 Reimplement in terms of get_child_status.
2567 (wait_for_termination_1, interruptible_wait_for_termination):
2568 Remove. All callers changed to use wait_for_termination.
2569 * syswait.h: Include <stdbool.h>, for bool.
2570 (record_child_status_change, interruptible_wait_for_termination):
2572 (record_deleted_pid, child_status_changed): New decls.
2573 (wait_for_termination): Adjust to API changes noted above.
2575 * bytecode.c, lisp.h (Qbytecode): Remove.
2576 No longer needed after 2012-11-20 interactive-p changes.
2578 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2580 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2581 the scroll margin, move point outside the margin. (Bug#13055)
2583 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2585 * gtkutil.c (my_log_handler): New function.
2586 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2588 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2590 * lisp.h (modify_region): Rename to...
2591 (modify_region_1): ...new prototype.
2592 * textprop.c (modify_region): Now static. Adjust users.
2593 * insdel.c (modify_region): Rename to...
2594 (modify_region_1): ...new function to work with current buffer.
2595 Adjust comment and users. Use true and false for booleans.
2597 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2599 * alloc.c (free_save_value): New function.
2600 (safe_alloca_unwind): Use it.
2601 * lisp.h (free_save_value): New prototype.
2602 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2604 (save_excursion_restore): Adjust to match saved data structure.
2605 Use free_save_value to offload some work from GC. Drop obsolete
2608 2012-12-03 Chong Yidong <cyd@gnu.org>
2610 * fileio.c (Vauto_save_list_file_name): Doc fix.
2612 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2614 * w32fns.c: Remove prototype of atof.
2615 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2617 (file_dialog_callback): Make it UINT_PTR.
2619 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2622 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2623 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2626 2012-12-03 Glenn Morris <rgm@gnu.org>
2628 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2630 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2632 Fix xpalloc confusion after memory is exhausted.
2633 * alloc.c (xpalloc): Comment fix.
2634 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2635 and signals an error, do not clear charset_table_size, as
2636 charset_table is still valid.
2637 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2639 Use execve to avoid need to munge environ (Bug#13054).
2640 * callproc.c (Fcall_process):
2641 * process.c (create_process):
2642 Don't save and restore environ; no longer needed.
2643 * callproc.c (child_setup):
2644 Use execve, not execvp, to preserve environ.
2646 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2648 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2650 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2652 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2653 display for sliced images (Bug#10500).
2655 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2657 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2659 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2660 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2662 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2664 * xdisp.c (window_outdated): Remove eassert since it hits
2665 some suspicious corner cases (see Bug#13007 and Bug#13012).
2666 (mode_line_update_needed): New function.
2667 (redisplay_internal, redisplay_window): Use it.
2668 (ensure_selected_frame): New function.
2669 (redisplay_internal, unwind_redisplay): Use it.
2670 (redisplay_internal): Move comment about buffer_shared...
2671 (buffer_shared_and_changed): ...near to its real use.
2673 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2675 * callproc.c (Fcall_process): Don't misreport vfork failure.
2677 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2679 * callproc.c (Fcall_process): Fix vfork portability problems.
2680 Do not assume that fd[0], count, filefd, and save_environ survive
2681 vfork. Fix bug whereby wrong errno value could be reported for
2682 pipe failure. Some minor cleanups, too, as follows. Move buf and
2683 bufsize to the context where they're needed. Change new_argv to
2684 be of type char **, as this is more convenient and avoids casts.
2685 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2686 Now local constants, not macros.
2688 2012-11-18 Kenichi Handa <handa@gnu.org>
2690 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2691 for the variable "f".
2693 2012-11-13 Kenichi Handa <handa@gnu.org>
2695 * font.c (font_unparse_xlfd): Exclude special characters from the
2696 generating XLFD name.
2698 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2700 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

2702 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2704 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2711 * lread.c (readbyte_from_file): Assume EINTR is defined.
2712 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2713 Assume EIO and EAGAIN are defined.
2714 * unexcoff.c (write_segment): Assume EFAULT is defined.
2716 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2718 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2721 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2722 highlighting on the frame was cleared. Prevents assertion
2723 violations when repeatedly clicking on the "Top" link of the
2724 "bread-crumbs" in Info buffers.
2726 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2728 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2730 2012-11-24 Ken Brown <kbrown@cornell.edu>
2732 * keyboard.c (HAVE_MOUSE):
2733 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2734 were always defined.
2736 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2738 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2739 between bpos_covered and bpos_max. This fixes cursor display when
2740 several display strings follow each other.
2742 * .gdbinit (pgx): If the glyph's object is a string, display the
2743 pointer to string data, rather than the value of the string object
2744 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2746 * indent.c (Fvertical_motion): If the starting position is covered
2747 by a display string, return to one position before that, to avoid
2748 overshooting it inside move_it_to. (Bug#12930)
2750 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2752 * frame.h (struct frame): Remove display_preempted member

2755 * w32menu.c (pending_menu_activation): Remove since not
2757 (set_frame_menubar): Adjust user.
2758 * w32term.h (struct x_output): Drop outdated #if 0 code.
2759 (struct w32_output): Use bitfields for explicit_parent,
2760 asked_for_visible and menubar_active members.
2761 Drop unused pending_menu_activation member.
2762 * xterm.h (struct x_output): Drop outdated #if 0 code.
2763 Use bitfields for explicit_parent, asked_for_visible,
2764 has_been_visible and net_wm_state_hidden_seen members.
2766 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2768 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2769 of a literal "/". (Bug#12955)
2770 (gl-stamp): Invoke fc.exe directly, not through cmd.
2772 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2774 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2775 * dired.c: Assume HAVE_DIRENT_H.
2776 (NAMLEN): Remove, replacing with ...
2777 (dirent_namelen): New function. All uses changed. Use the GNU macro
2778 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2779 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2780 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2781 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2783 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2784 * ndir.h: Rename to ../nt/inc/dirent.h.
2785 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2786 Do not include <dirent.h>; no longer needed.
2787 * w32.c: Include <dirent.h> rather than "ndir.h".
2789 2012-11-23 Chong Yidong <cyd@gnu.org>
2791 * xftfont.c (xftfont_open): Remove duplicate assignment.
2793 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2795 * alloc.c (Fgarbage_collect): Unblock input after clearing
2796 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2797 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2798 * msdos.c (IT_frame_up_to_date): Use it here...
2799 * w32term.c (w32_frame_up_to_date): ...here...
2800 * xterm.c (XTframe_up_to_date): ...and here...
2801 * nsterm.m (ns_frame_up_to_date): ...but not here.
2802 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2804 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2805 Do not check whether GC is in progress.
2807 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2809 * xdisp.c (window_buffer_changed): New function.
2810 (update_menu_bar, update_tool_bar): Use it to
2811 simplify large 'if' statements.
2812 (redisplay_internal): Generalize commonly used
2813 'tail' and 'frame' local variables.
2815 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2817 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2818 with Windows system header.
2820 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2822 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2823 * alloc.c: Assume unistd.h exists.
2824 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2825 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2826 (getwd) [USG]: Remove; no longer needed.
2827 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2828 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2829 * w32.h (getcwd): Remove decl.
2831 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2833 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2834 Make it set selected_window as well.
2835 (update_tool_bar): Use it.
2837 2012-11-21 Ken Brown <kbrown@cornell.edu>
2839 * emacs.c (main): Set the G_SLICE environment variable for all
2840 Cygwin builds, not just GTK builds. See
2841 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2843 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2845 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2846 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2847 Define for the MSVC compiler.
2849 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2851 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2852 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2853 dostounix_filename. Prevents crashes down the road, because
2854 dostounix_filename assumes it gets a unibyte string.
2855 Reported by Michel de Ruiter <michel@sentient.nl>, see
2856 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2858 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

2862 * lread.c (init_obarray): Set `function' fields to Qnil.
2863 * eval.c (Fcommandp): Ignore Qunbound.
2864 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2865 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2866 Test NILP rather than Qunbound.
2867 (Ffmakunbound): Set to Qnil.
2868 (Fsymbol_function): Never signal an error.
2869 (Finteractive_form): Ignore Qunbound.
2871 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2873 * eval.c (interactive_p): Remove no-longer-used decl.
2875 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2877 * xdisp.c (buffer_shared): Adjust comment.
2878 (buffer_shared_and_changed): New function.
2879 (prepare_menu_bars, redisplay_internal): Use it to
2880 decide whether all windows or frames should be updated.
2881 (window_outdated): New function.
2882 (text_outside_line_unchanged_p, redisplay_window): Use it.
2883 (redisplay_internal): Likewise. Fix indentation.
2885 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2887 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2888 (syms_of_eval): Remove corresponding defsubr.
2889 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2891 2012-11-19 Daniel Colascione <dancol@dancol.org>
2893 * w32fns.c (Fx_file_dialog):
2894 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2895 cygwin_convert_file_name*.
2897 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2898 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2900 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2902 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2904 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2906 * w32select.c: Include w32common.h before w32term.h, so that
2907 windows.h gets included before w32term.h uses some of its
2908 features, see below.
2910 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2912 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2914 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2916 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2918 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2919 (ns_select): Return at once if events are held (Bug#12834).
2921 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2923 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2924 Needed following 2012-10-20 change. (Bug#12902)
2926 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2928 * w32proc.c (waitpid): Remove unused label get_result.
2930 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2932 * makefile.w32-in (SYSWAIT_H): New macro.
2933 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2934 ($(BLD)/sysdep.$(O)): Update dependencies.
2936 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2938 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2939 * callproc.c (relocate_fd): Assume F_DUPFD.
2940 * emacs.c, term.c (O_RDWR): Remove.
2941 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2942 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2943 * nsterm.m: Assume <fcntl.h> exists.
2944 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2945 (create_pty, Fmake_network_process, server_accept_connection)
2946 (wait_reading_process_output, init_process_emacs):
2948 (wait_reading_process_output): Put in a special case for WINDOWSNT
2949 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2950 It's not clear this is needed, but it's a more-conservative change.
2951 (create_process): Assume FD_CLOEXEC.
2952 (create_process, create_pty): Assume O_NOCTTY.
2953 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2954 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2955 Omit if not DOS_NT, since F_GETFL is not defined there.
2956 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2957 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2959 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2960 lack it, since gnulib guarantees this.
2961 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2963 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2965 * w32.c (faccessat): Pretend that directories have the execute bit
2966 set. Emacs expects that, e.g., in files.el:cd-absolute.
2968 * w32proc.c (create_child): Don't clip the PID of the child
2969 process to fit into an Emacs integer, as this is no longer a
2971 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2972 reaping only the process specified by PID argument, if that is
2973 positive. Use PID instead of dead_child to know which process to
2974 reap. Wait for the child to die only if WNOHANG is not in
2976 (sys_select): Don't set dead_child.
2978 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2979 as it is no longer needed.
2981 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2983 (record_child_status_change): Remove the setting of
2984 record_at_most_one_child for the !WNOHANG case.
2986 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2988 Fix problems in ns port found by static checking.
2989 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2990 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2991 not to process group.
2992 (ns_select): Use emacs_write, not write, as that's more robust
2993 in the presence of signals.
2994 (fd_handler:): Check for read errors.
2996 2012-11-16 Glenn Morris <rgm@gnu.org>
2998 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3000 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3002 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3004 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3006 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3007 use the same value of thread handle.
3008 (start_timer_thread): If the timer thread exited (due to error),
3009 clean up by closing the two handles it used. Duplicate the caller
3010 thread's handle here, so it gets duplicated only once, when
3011 launching the timer thread. Set priority of the timer thread, not
3013 (getitimer): Don't duplicate the caller thread's handle here.
3016 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3018 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3021 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3023 Remove no-longer-used pty_max_bytes variable.
3024 * process.c (pty_max_bytes): Remove; unused.
3025 (send_process): Do not set it.
3027 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3029 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3030 Update dependencies.
3032 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3034 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3035 This follows up on the 2012-09-29 patch that removed indirection
3036 for the 'function' field. Reported by Sergey Vinokurov in
3037 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3039 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3041 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3042 different name, as the MS runtime does not have such a function,
3043 and probably never will.) All callers changed. Ignore DIRFD
3044 value if PATH is an absolute file name, to match Posix spec
3045 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3048 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3050 * xdisp.c (echo_area_display, redisplay_internal):
3051 Omit redundant check whether frame_garbaged is set.
3053 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3055 Use faccessat, not access, when checking file permissions (Bug#12632).
3056 This fixes a bug that has been present in Emacs since its creation.
3057 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3058 which must set some sort of record. (Torek's bug report was against
3059 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3060 same common flaw.) See Torek's Usenet posting
3061 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3062 Posted: Fri Apr 8 14:18:56 1983.
3063 * Makefile.in (LIB_EACCESS): New macro.
3065 * callproc.c (init_callproc):
3066 * charset.c (init_charset):
3067 * fileio.c (check_existing, check_executable, check_writable)
3069 * lread.c (openp, load_path_check):
3070 * process.c (allocate_pty):
3072 Use effective UID when checking permissions, not real UID.
3073 * callproc.c (init_callproc):
3074 * charset.c (init_charset):
3075 * lread.c (load_path_check, init_lread):
3076 Test whether directories are accessible, not merely whether they exist.
3077 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3078 * fileio.c (check_existing, check_executable, check_writable)
3080 Use symbolic names instead of integers for the flags, as they're
3082 (check_writable): New arg AMODE. All uses changed.
3083 Set errno on failure.
3084 (Ffile_readable_p): Use faccessat, not stat + open + close.
3085 (Ffile_writable_p): No need to call check_existing + check_writable.
3086 Just call check_writable and then look at errno. This saves a syscall.
3087 dir should never be nil; replace an unnecessary runtime check
3088 with an eassert. When checking the parent directory of a nonexistent
3089 file, check that the directory is searchable as well as writable, as
3090 we can't create files in unsearchable directories.
3091 (file_directory_p): New function, which uses 'stat' on most platforms
3092 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3093 (Ffile_directory_p, Fset_file_times): Use it.
3094 (file_accessible_directory_p): New function, which uses a single
3095 syscall for efficiency.
3096 (Ffile_accessible_directory_p): Use it.
3097 * xrdb.c (file_p): Use file_directory_p.
3098 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3099 * lread.c (openp): When opening a file, use fstat rather than
3100 stat, as that avoids a permissions race. When not opening a file,
3101 use file_directory_p rather than stat.
3102 (dir_warning): First arg is now a usage string, not a format.
3103 Use errno. All uses changed.
3104 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3105 that merely introduced a race.
3106 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3107 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3108 and similarly for the other O_* flags.
3109 * w32.c (sys_faccessat): Rename from sys_access and switch to
3110 faccessat's API. All uses changed.
3111 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3112 (magic_db): Rename from magic_file_p.
3113 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3114 char *, so that we don't have to test for file existence
3115 separately from opening the file for reading. This removes a race
3116 fixes a permission-checking problem, and simplifies the code.
3118 (file_p): Remove; no longer needed.
3120 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3122 Omit glyphs initialization at startup.
3123 * dispnew.c (glyphs_initialized_initially_p): Remove.
3124 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3125 (Fredraw_frame): Move actual code from here...
3126 (redraw_frame): ...to here. Add eassert. Adjust comment.
3127 (Fredraw_display): Use redraw_frame.
3128 * xdisp.c (clear_garbaged_frames): Likewise.
3130 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3132 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3133 passed to pint2str and pint2hrstr to be at most the size of the
3134 frame's decode_mode_spec_buffer. This avoids crashes with very
3135 large values of FIELD_WIDTH argument to decode_mode_spec.
3138 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3140 Fix a race with verify-visited-file-modtime (Bug#12863).
3141 Since at least 1991 Emacs has ignored an mtime difference of no
3142 more than one second, but my guess is that this was to work around
3143 file system bugs that were fixed long ago. Since the race is
3144 causing problems now, let's remove that code.
3145 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3146 whose time stamp is off by no more than a second. Insist that the
3147 file time stamps match exactly.
3149 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3151 * frame.h (struct frame): Convert external_tool_bar member to
3152 1-bit unsigned bitfield.
3153 * termhooks.h (struct terminal): Remove mouse_moved member since
3154 all users are long dead. Adjust comment on mouse_position_hook.
3156 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3158 Simplify by using FOR_EACH_FRAME here and there.
3159 * frame.c (next_frame, prev_frame, other_visible_frames)
3160 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3161 * w32term.c (x_window_to_scroll_bar): Likewise.
3162 * window.c (window_list): Likewise.
3163 * xdisp.c (x_consider_frame_title): Likewise.
3164 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3165 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3166 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3167 * xmenu.c (menubar_id_to_frame): Likewise.
3168 * xselect.c (frame_for_x_selection): Likewise.
3169 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3170 (x_window_to_menu_bar): Likewise.
3171 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3173 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3175 * data.c (Qdefalias_fset_function): Now static.
3177 Another tweak to vectorlike_header change.
3178 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3179 Remove, and replace all uses with ...
3180 (next_in_free_list, set_next_in_free_list):
3181 New functions, which respect C's aliasing rules better.
3183 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3185 * window.c (list4i): Rename from 'quad'. All uses changed.
3186 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3188 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3190 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3191 warning about mixing declarations and code in ISO C90.
3193 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3195 * window.c (Fsplit_window_internal): Set combination limit of
3196 new parent window to t iff Vwindow_combination_limit is t;
3197 fixing a regression introduced with the change from 2012-09-22.
3198 (Fset_window_combination_limit): Fix doc-string.
3200 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3202 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3203 amount when the scroll margins are too large. When scrolling
3204 backwards in the buffer, give up if cannot reach point or the
3205 scroll margin within a reasonable number of screen lines.
3206 Fixes point position in window under scroll-up/down-aggressively when
3207 point is positioned many lines beyond the window top/bottom.
3210 * ralloc.c (relinquish): If real_morecore fails to return memory
3211 to the system, don't crash; instead, leave the last heap
3212 unchanged and return. (Bug#12774)
3214 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3216 * lisp.h (AUTOLOADP): New macro.
3217 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3218 * data.c (Ffset): Remove special ad-advice-info handling.
3219 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3221 (Finteractive_form): Simplify.
3222 (Fquo): Don't insist on having at least 2 arguments.
3223 (Qdefalias_fset_function): New var.
3225 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3227 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3229 * nsfont.m (Qcondensed, Qexpanded): New variables.
3230 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3231 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3233 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3235 Fix recently introduced crash on MS-Windows (Bug#12839).
3236 * w32term.h (struct scroll_bar): Use convenient header.
3237 (SCROLL_BAR_VEC_SIZE): Remove.
3238 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3240 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3242 Tweak last vectorlike_header change.
3243 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3244 vectorlike object on the free list. This is introduced to avoid
3245 some (but not all) pointer casting and aliasing problems, see
3246 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3247 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3249 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3251 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3253 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3254 been removed, so remove them here also.

3274 Use same hash function for hashfn_profiler as for hash_string etc.
3275 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3276 * lisp.h (sxhash_combine): New inline function, with the contents
3277 of the old SXHASH_COMBINE.
3278 * profiler.c (hashfn_profiler): Use it, instead of having a
3279 special hash function containing a comparison that always yields 1.
3281 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3283 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3284 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3285 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3288 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3290 * image.c (xpm_make_color_table_h): Fix compiler error because
3291 make_hash_table changed.
3293 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3295 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3297 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3299 Use ad-hoc comparison function for the profiler's hash-tables.
3300 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3301 (make_log): Use them.
3302 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3303 call Fequal any more.

3312 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3313 (hash_lookup, hash_remove_from_table): Move assertion checking of
3314 hashfn result here. Check hash-equality before calling cmpfn.

3326 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3327 value of w32-scroll-lock-modifier is neither nil nor one of the
3328 known key modifiers. (Bug#12806)
3330 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3332 Shrink struct vectorlike_header to the only size field.
3333 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3335 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3336 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3337 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3338 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3339 information from the vector header. Adjust comment.

3354 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3355 (large_vectors): Change type to struct large_vector.
3356 (allocate_vector_from_block): Simplify.
3357 (PSEUDOVECTOR_NBYTES): Replace with...
3358 (vector_nbytes): ...new function. Adjust users.

3360 (allocate_vectorlike): Likewise.
3361 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3362 Add easserts. Adjust XSETPVECTYPESIZE usage.
3363 (allocate_buffer): Use BUFFER_PVEC_INIT.
3364 (live_vector_p): Adjust to match large vector.
3365 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3366 * buffer.h (struct buffer): Add next member.
3367 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3369 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

3377 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3379 * keyboard.c (event_to_kboard): Do not dereference
3380 frame_or_window field of SELECTION_REQUEST_EVENT
3381 and SELECTION_CLEAR_EVENT events (Bug#12814).
3382 * xterm.h (struct selection_input_event): Adjust comment.
3384 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3386 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3387 such as Scroll Lock, if the respective keys are treated as
3388 function keys, not as modifiers. This avoids destroying non-ASCII
3389 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3391 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3393 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3395 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3397 Restore some duplicate definitions (Bug#12814).
3398 This undoes part of the 2012-11-03 changes. Some people build
3399 with plain -g rather than with -g3, and they need the duplicate
3400 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3401 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3402 Define as macros, as well as as enums or as constants.
3404 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3406 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3407 to keypad keys (Bug#12816).
3409 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3411 Minor adjustments of recently-changed frame functions.
3412 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3413 known to be a frame (we're in the FRAMEP branch).
3414 * lisp.h (Qframep): Remove decl. frame.h declares this.
3415 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3416 since they're meant for Lisp fixnum values.
3418 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3420 * window.c (Fwindow_combination_limit): Revert to the only
3421 required argument and adjust docstring as suggested in
3422 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3423 by Martin Rudalics <rudalics@gmx.at>.
3425 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3427 Widely used frame validity and checking functions.
3428 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3429 * frame.c (decode_live_frame, decode_any_frame): New functions.
3430 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3431 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3432 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

3439 (frame_buffer_list, frame_buffer_predicate): Remove.
3440 * lisp.h (frame_buffer_predicate): Remove prototype.
3441 * buffer.c (Fother_buffer): Use decode_any_frame.
3442 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3443 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3444 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3445 (Fclose_font, Ffont_info): Use decode_live_frame.
3446 * fontset.c (check_fontset_name): Likewise.
3447 * terminal.c (Fframe_terminal): Likewise.
3448 * w32fns.c (check_x_frame): Likewise.
3449 * window.c (Fminibuffer_window, Fwindow_at)
3450 (Fcurrent_window_configuration): Likewise.
3451 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3452 Likewise. Allow zero number of arguments. Adjust docstring.
3453 * dispnew.c (Fredraw_frame): Likewise.
3454 * xfaces.c (frame_or_selected_frame): Remove.
3455 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3456 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3457 (Fframe_face_alist): Use decode_live_frame.
3458 * xfns.c (check_x_frame): Likewise.
3460 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3462 * window.c (quad): New function.
3463 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3464 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3465 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3466 (Fwindow_line_height): Use it.
3467 (Fwindow_fringes): Use list3.
3468 (Fwindow_scroll_bars): Use list4.
3469 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3470 (Fwindow_combination_limit): Allow zero number of arguments.
3472 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3474 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3476 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3477 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3478 file descriptor 2 for standard error. (Bug#12805)
3480 2012-11-05 Chong Yidong <cyd@gnu.org>
3482 * process.c (wait_reading_process_output): Revert previous change.
3484 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3486 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3487 This removes code that has been obsolete since around 1990.
3488 * callproc.c (Fcall_process):
3490 * process.c (create_process):
3491 * term.c (dissociate_if_controlling_tty):
3492 Assume setsid exists.
3493 * callproc.c (child_setup): Assume setpgid exists and behaves as
3494 per POSIX.1-1988 or later.
3495 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3496 * emacs.c (shut_down_emacs):
3497 * sysdep.c (sys_suspend, init_foreground_group):
3498 Assume getpgrp behaves as per POSIX.1-1998 or later.
3499 * msdos.c (setpgrp): Remove.
3500 (tcgetpgrp, setpgid, setsid): New functions.
3501 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3502 * term.c (no_controlling_tty): Remove; unused.
3503 * w32proc.c (setpgrp): Remove.
3504 (setsid, tcgetpgrp): New functions.
3506 Simplify by assuming __fpending.
3507 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3508 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3509 Do not assume that __fpending's result fits in int.
3511 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3513 Remove EMACS_OUTQSIZE+sleep hack.
3514 * dispnew.c (update_frame_1): Remove hack for terminals slower
3515 than 2400 bps, which throttled Emacs by having it sleep.
3516 This code hasn't worked since at least 2007, when the multi-tty stuff
3517 was added, and anyway those old terminals are long dead.
3518 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3519 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3521 Fix data-loss with --version (Bug#9574).
3522 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3523 as we can't assume that emacs_strerror is initialized, and strerror
3524 is good enough here.
3525 (main): Invoke atexit earlier, to catch earlier instances of
3526 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3528 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3530 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3531 (keyDown): Remap keypad keys to X11 virtual key codes.
3533 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3535 Fix data-loss with --batch (Bug#9574).
3536 * emacs.c: Include <close-stream.h>.
3537 (close_output_streams): New function.
3538 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3539 and handles errors appropriately.
3540 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3543 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3544 The symptom is a diagnostic "GLib-WARNING **: In call to
3545 g_spawn_sync(), exit status of a child process was requested but
3546 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3547 waitpid(), so exit status can't be returned." The diagnostic
3548 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3549 The real bug is a race condition between Emacs and glib: Emacs
3550 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3551 so that glib can't find it. Work around the bug by invoking
3552 waitpid only on subprocesses that Emacs itself creates.
3553 * process.c (create_process, record_child_status_change):
3554 Don't use special value -1 in pid field, as the caller now must
3555 know the pid rather than having the callee infer it.
3556 The inference was sometimes incorrect anyway, due to another race.
3557 (create_process): Set new 'alive' member if child is created.
3558 (process_status_retrieved): New function.
3559 (record_child_status_change): Use it.
3560 Accept negative 1st argument, which means to wait for the
3561 processes that Emacs already knows about. Move special-case code
3562 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3563 processes that have already been waited for, by testing and
3564 clearing new 'alive' member.
3565 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3566 now does this internally.
3567 (handle_child_signal): Let record_child_status_change do all
3568 the work, since we do not want to reap all exited child processes,
3569 only the child processes that Emacs itself created.
3570 * process.h (Lisp_Process): New boolean member 'alive'.
3572 Omit duplicate definitions no longer needed with gcc -g3.
3573 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3574 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3575 Define only as macros. There's no longer any need to also define
3576 these symbols as enums or as constants, since we now assume
3577 gcc -g3 when debugging.
3579 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3581 * lisp.mk: Adjust comments to the fact that term/internal is now
3582 loaded from loadup.el.
3584 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3585 (msdos_fatal_signal): New function.
3586 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3589 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3590 for GCC versions before 4.
3591 (emacs_raise): Define to call msdos_fatal_signal.
3593 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3594 iterator when starting in the middle of a display or overlay
3597 2012-11-03 Chong Yidong <cyd@gnu.org>
3599 * process.c (wait_reading_process_output): Clean up the last
3602 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3604 * process.c (wait_reading_process_output): Avoid a race condition
3605 with SIGIO delivery (Bug#11536).
3607 2012-11-03 Chong Yidong <cyd@gnu.org>
3609 * buffer.c (cursor_type): Untabify docstring.
3611 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3613 * frame.h (struct frame): Drop can_have_scroll_bars member
3614 which is meaningless for a long time. Adjust comments.
3615 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3616 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3618 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3620 * window.c (decode_next_window_args): Update window arg after
3621 calling decode_live_window and so fix crash reported at
3622 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3623 by Juanma Barranquero <lekktu@gmail.com>.
3624 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3625 * font.c (Ffont_at): Likewise.
3627 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3629 * widget.c (resize_cb): New function.
3630 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3631 (EmacsFrameResize): Check if all is up to date before changing frame
3634 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3636 Implement backtrace output for fatal errors on MS-Windows.
3637 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3638 (BACKTRACE_LIMIT_MAX): New macro.
3639 (w32_backtrace): New function.
3640 (emacs_abort): Use w32_backtrace when the user chooses not to
3641 attach a debugger. Update the text of the abort dialog.
3643 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3645 Window-related stuff cleanup here and there.
3646 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3647 Use decode_any_window.
3648 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3649 * xdisp.c (Fformat_mode_line): Likewise.
3650 * font.c (Ffont_at): Use decode_live_window.
3651 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3652 * window.c (decode_next_window_args): Likewise.
3653 (decode_any_window): Remove static.
3654 * window.h (decode_any_window): Add prototype.
3655 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3656 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3659 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3661 Remove pad from struct input_event.
3662 * termhooks.h (struct input_event): Remove padding field.
3664 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3665 member is never cons for a long time. Adjust comment.
3666 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3667 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3668 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3669 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3671 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3673 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3675 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3677 Fix crash when using Emacs as commit editor for git (Bug#12697).
3678 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3679 and it is configured in conf_post.h.
3680 (Fcall_process): Don't invoke both setsid and setpgid; the former
3681 is enough, if it exists.
3682 * callproc.c (Fcall_process, child_setup):
3683 * process.c (create_process): Use setpgid.
3684 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3686 * dispnew.c (init_display): Initialize the foreground group
3687 if we are running a tty display.
3688 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3689 * lisp.h (init_foreground_group): New decl.
3690 * sysdep.c (inherited_pgroup): New static var.
3691 (init_foreground_group, tcsetpgrp_without_stopping)
3692 (narrow_foreground_group, widen_foreground_group): New functions.
3693 (init_sys_modes): Narrow foreground group.
3694 (reset_sys_modes): Widen foreground group.
3696 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3698 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3700 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3702 * minibuf.c (read_minibuf): Restore current buffer since
3703 choose_minibuf_frame calling Fset_frame_selected_window may
3704 change it (Bug#12766).
3706 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3708 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3710 2012-10-30 Kenichi Handa <handa@gnu.org>
3712 * font.c (Ffont_at): If WINDOW is specified and it is not
3713 displaying the current buffer, signal an error.
3715 2012-10-29 Daniel Colascione <dancol@dancol.org>
3717 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3718 In preparation for fixing bug#12739, move these functions from
3721 * coding.h, coding.c: ... to here, and compile them only when
3722 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3723 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3725 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3727 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3728 (timer_loop, getitimer, setitimer): Use it instead of
3729 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3731 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3734 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

3738 (last_appdefined_event): Remove.
3739 (ns_select): Initialize t from last_appdefined_event_data instead
3740 of [last_appdefined_event data1].
3741 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3742 remove last_appdefined_event (Bug#12698).
3744 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3746 * frame.c (x_set_font): Catch internal error.
3748 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3750 Avoid overflow in w32 implementation of interval timers.
3751 When possible, for ITIMER_PROF count only times the main thread
3753 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3754 'volatile ULONGLONG' types. All the other data which was
3755 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3756 (GetThreadTimes_Proc): New typedef.
3757 (w32_get_timer_time): New function, returns a suitable time value
3759 (timer_loop): Enter critical section when accessing ULONGLONG
3760 values of the itimer_data struct, as these accesses are no longer
3761 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3762 Remove unused variable.
3763 (init_timers): Initialize s_pfn_Get_Thread_Times.
3764 (start_timer_thread): Don't assign itimer->caller_thread here.
3765 (getitimer): Assign itimer->caller_thread here.

3771 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3772 mouse movement events if the menu bar is active. This avoids
3773 producing a busy "hour-glass" cursor by Windows if the mouse
3774 pointer is positioned over a tooltip shown for some menu item.
3776 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3778 Don't assume process IDs fit in int.
3779 * emacs.c (shut_down_emacs) [!DOS_NT]:
3780 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3781 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3782 Use pid_t, not int, to store process IDs, as 'int'
3783 is not wide enough on a few platforms (e.g., AIX and IRIX).
3785 2012-10-23 Kenichi Handa <handa@gnu.org>
3787 The following change is to make face-font-rescale-alist work
3788 correctly for non-ASCII fonts.
3790 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3791 (font_open_for_lface): Handle Vface_font_rescale_alist.

3806 2012-10-21 Glenn Morris <rgm@gnu.org>
3808 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3810 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3812 Port to OpenBSD 5.1.
3813 * frame.c (Fmouse_position, Fmouse_pixel_position):
3814 * xdisp.c (produce_stretch_glyph):
3815 Declare local vars only when they're needed.
3816 This is clearer and avoids a warning on OpenBSD about unused vars.

3818 This is safer, and avoids OpenBSD warnings about unused vars.
3819 * keyboard.c (record_menu_key): Remove unnecessary decl.
3820 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3821 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3822 as our definition clashes with OpenBSD's.
3823 * xfaces.c (load_face_colors, check_lface_attrs)
3824 (get_lface_attributes_no_remap, get_lface_attributes)
3825 (lface_fully_specified_p, x_supports_face_attributes_p)
3826 (tty_supports_face_attributes_p, face_fontset, realize_face)
3827 (realize_x_face, realize_tty_face):
3828 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3829 merely Lisp_Object *. This is more informative and avoids
3830 a warning on OpenBSD about accessing beyond an object's size.
3832 2012-10-20 Chong Yidong <cyd@gnu.org>
3834 * lread.c (Fload): Doc fix (Bug#12592).

3860 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3861 (staticpro): If we run out of staticpro slots, die with an
3862 informative error instead of just calling emacs_abort.
3864 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3866 Fix two flaws reported by Dmitry Antipov.

4124 the same pointer-to-int (now pointer-to-boolean) &input_pending,

4126 input_pending. All callers changed.
4127 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4128 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

4168 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4170 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4171 match what GetLastError returns. Explain why the function is
4174 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4175 'is_tooltip_frame', to avoid confusion with its global namesake.
4177 2012-10-08 Daniel Colascione <dancol@dancol.org>
4179 * xdisp.c (start_hourglass): Call w32_note_current_window when
4180 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4181 build that caused Emacs to display the hourglass cursor forever.
4183 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4184 which is broken under remote desktop, calculate the number of
4185 colors available for a display based on the display's number of
4186 planes and number of bits per pixel per plane. (bug#10397).
4188 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4190 * nsfont.m (Vfonts_in_cache): New variable.
4191 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4192 are used. Add cached fonts to Vfonts_in_cache.
4193 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4195 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4197 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4199 (FONT_H): Define after FRAME_H.
4200 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4201 Update dependencies.
4203 * w32term.c: Remove leftover declaration of keyboard_codepage.
4205 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4207 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4208 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4209 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4210 (GLOBAL_SOURCES): Add cygw32.c.
4211 ($(BLD)/unexw32.$(O)):
4213 ($(BLD)/w32console.$(O)):
4214 ($(BLD)/w32fns.$(O)):
4215 ($(BLD)/w32heap.$(O)):
4216 ($(BLD)/w32menu.$(O)):
4217 ($(BLD)/w32proc.$(O)): Add w32common.h.
4219 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4221 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4223 2012-10-08 Daniel Colascione <dancol@dancol.org>
4225 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4226 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4227 accidental message numbering hole. Change other messages to
4230 * w32select.h (HAVE_W32SELECT): Remove.
4232 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4233 w32common.h instead of w32heap.h.
4235 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4236 (get_allocation_unit, get_processor_type, get_w32_major_version)
4237 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4238 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4239 (OS_NT, os_subtype, cache_system_info): Move declarations to
4242 * w32heap.c: Include w32common.h.
4243 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4244 (w32_minor_version, w32_build_number, w32_subtype):
4245 Remove duplicate definitions.
4247 * w32fns.c: Include w32common.h; include w32heap.h only in
4250 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4251 Use `report_file_error' instead of `error' in order to better
4252 inform users of what went wrong. Increase NTGUI_UNICODE file
4253 dialog box file name length to 32k, the maximum allowed by the NT
4256 * w32common.h: New file.
4257 (ROUND_UP, ROUND_DOWN, get_page_size)
4258 (get_allocation_unit, get_processor_type, get_w32_major_version)
4259 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4260 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4261 (OS_NT, os_subtype, cache_system_info): Move here.
4263 * unexw32.c, unexcw.c: Include w32common.h.
4265 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4266 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4267 to call syms_of_w32select.
4269 * cygw32.h: Remove obsolete EXFUN declarations.
4271 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4273 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4274 of w32inevt.o from SOME_MACHINE_OBJECTS.
4276 2012-10-08 Daniel Colascione <dancol@dancol.org>
4278 * image.c: Permanent fix for JPEG compilation issue --- limit
4279 jpeglib `boolean' redefinition to Cygwin builds.
4281 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4283 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4285 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4288 2012-10-08 Daniel Colascione <dancol@dancol.org>
4290 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4291 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4292 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4293 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4294 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4295 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4296 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4297 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4298 now a supported configuration.
4300 * Makefile.in: consolidate image variables into LIBIMAGE; add
4301 W32_OBJ and W32_LIBS. Compile new files.
4304 (_DebPrint) declare tracing facility for W32 debugging. We need
4305 to unify tracing later.
4307 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4308 unconditional use of W32 Unicode functions. Cygwin runs only on
4309 100% Unicode operating systems.
4311 * cygw32.c: New file. Define Cygwin-specific facilities.
4312 (Fcygwin_convert_path_to_windows)
4313 (Fcygwin_convert_path_from_windows): New user functions for
4314 accessing Cygwin path-munging routines.
4316 * cygw32.h: New file.
4317 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4318 UTF-16LE strings temporarily inside non-Lisp-visible string
4321 (w32_strerror): Just what it says on the tin.
4323 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4324 also run for Cygwin; both systems have the same problem with using
4325 GUI facilities in a forked child. Also call syms_of_cygw32,
4326 syms_of_w32select in correct places.
4328 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4329 needs fork-then-exec for daemon launching.
4331 * font.h: Include frame.h.
4333 * image.c: Use the image library cache machinery only when we're
4334 compiling for native WINDOWSNT; Cygwin can use shared libraries
4335 like any other Unixlike system.
4337 * keyboard.c: Clarify a comment regarding the input loop.
4339 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4340 functions directly instead of trying to detect at runtime that our
4341 host operating system supports them. We make this change for two
4342 reasons: Cygwin lacks support for the multibyte character
4343 conversion functions used by the legacy menu code, and Cygwin
4344 never needs to rely on non-Unicode APIs.
4346 * unexw32.c (hinst): Declare extern.
4348 * w32.c: Change header order;
4349 (w32_strerror): Move to w32fns.c because we need it for
4350 non-WINDOWSNT builds.
4352 * w32.h: Add #error macro to make sure we don't include w32.h for
4353 Cygwin builds. Remove w32select declarations.
4355 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4356 w32fns.c. w32console.c is WINDOWSNT-only.
4358 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4359 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4361 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4362 (w32_major_version, w32_minor_version, w32_build_number)
4363 (os_subtype, sound_type): Define here
4364 (w32_defined_color): Make color parameter const for consistency
4365 with other _defined_color functions.
4366 (w32_createwindow): Unconditionally call w32_init_class instead of
4367 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4368 through the code is complex and unnecessary because class
4369 registration is practically free.
4370 (w32_name_of_message): New EMACSDEBUG-only function.
4371 (Fset_message_beep): Move here
4372 (Fx_open_connection): Require that the display name for Windows be
4373 "w32" for consistency, emacsclient disambiguation, and maybe, one
4374 day, multi-window-system support.
4375 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4376 Cygwin files for W32 GUI facilities, since these clearly don't
4377 expect Cygwin names.
4378 (_DebPrint): Define.
4379 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4380 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4381 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4382 (w32_last_error): Remove.
4384 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4386 * w32heap.c (syspage_mask): Declare here.
4387 (cache_system_info): Remove.
4389 * w32inevt.c (faked_key): Define globally, not statically.
4390 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4391 (w32_console_toggle_lock_key): Move to w32fns.c.
4393 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4395 * w32proc.c (_DebPrint): Move to w32fns.c.
4396 * w32select.c: Include string.h, stdio.h for Cygwin.
4397 * w32select.h: New File.
4399 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4401 (w32_message_fd): New variable. Under Cygwin, holds the file
4402 descriptor the system used to tell us about pending thread
4405 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4406 that prevented compilation under non-WINDOWSNT systems.
4408 (w32_initialize): Open /dev/windows and assign it to
4409 w32_message_fd. Provide w32 feature.
4411 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4412 (WM_EMACS_INPUT_READY): add.
4413 (prepend_msg, w32_message_fd): Declare globally.
4416 (keyboard_handle): Use only when WINDOWSNT.
4417 (notify_msg_ready): New function. Posts a message to the main
4418 thread's message queue under CYGWIN, which wakes up the main
4419 thread from select(2) by making the /dev/windows file descriptor
4420 ready. Under WINDOWSNT, it sets an event the same way the old
4423 (post, prepend_msg): Actually call notify_msg_ready instead of
4424 setting the input event directly.
4426 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4428 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4429 but it still has blocs in it, don't return it to the system,
4430 instead of aborting. (Bug#12402)
4432 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4434 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4436 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4437 MAC_OS_X_VERSION_10_6.
4438 (syms_of_nsterm): Remove comment about Panther and above for
4440 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4441 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4442 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4444 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4445 MAC_OS_X_VERSION_10_4.
4447 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4448 MAC_OS_X_VERSION_10_2.
4450 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4452 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4453 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4455 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4456 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4457 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4458 Remove ns_in_resize check.
4459 (ns_clear_frame_area): Remove resize handle code.
4461 * nsfns.m (ns_in_resize): Remove.
4462 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4463 Remove ns_in_resize check.
4465 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4467 Improve sys_siglist detection.
4468 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4469 defined as a macro, as is done in Solaris.
4470 (sys_siglist_entries): New macro.
4471 (save_strsignal): Use it.
4472 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4473 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4475 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4477 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4478 fullscreen/Fullscreen.
4480 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4481 tobar_height is new.
4483 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4484 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4485 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4486 (windowDidResize:): Check for correct window if old style fullscreen.
4487 Capitalize word in comment. Remove incorrect comment.
4488 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4489 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4490 error in drawing background.
4491 (toggleFullScreen:): Remove comment. Rearrange calls.
4492 Set toolbar values to zero, save old height in tobar_height.
4493 Restore tool bar height when leaving fullscreen.
4494 (canBecomeMainWindow): New function.
4496 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4498 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4500 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4502 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4504 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4505 that time stamps of directories could also be changed.
4506 Don't request the too broad GENERIC_WRITE, only the more restrictive
4507 FILE_WRITE_ATTRIBUTES access rights.
4509 * fileio.c (Fset_file_times): Special-case ignoring errors for
4510 directories only on MSDOS, not on MS-Windows.
4512 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4514 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4516 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4518 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4519 see whether CreateFile failed.
4521 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4523 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4524 to avoid similar races.
4525 * keyboard.c (pending_signals): Now bool, not int.
4527 Port timers to OpenBSD, plus check for timer failures.
4528 OpenBSD problem reported by Han Boetes.
4529 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4531 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4532 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4533 like OpenBSD, which has timer_settime but does not declare it.
4534 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4535 whether to use itimerspec-related primitives. All uses of
4536 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4538 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4540 * profiler.c (handle_profiler_signal): Fix a malloc race
4541 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4543 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4545 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4547 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4549 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4550 consistent with the change in return value of 'safe_strsignal'.
4552 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4554 Prefer plain 'static' to 'static inline' (Bug#12541).
4555 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4556 (bidi_set_sor_type, bidi_push_embedding_level)
4557 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4558 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4559 (bidi_cache_search, bidi_cache_ensure_space)
4560 (bidi_cache_iterator_state, bidi_cache_find)
4561 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4562 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4563 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4564 Now 'static', not 'static inline'.
4566 Count overruns when profiling; change units to ns.
4567 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4568 Give extra weight to samples after overruns, to attempt to count
4569 the time more accurately.
4570 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4571 the underlying primitives nominally do ns.
4572 (Fprofiler_cpu_start): Document the change. Mention that
4573 the sampling intervals are only approximate.
4575 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4577 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4579 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4580 case for the special 0 coding-system.
4582 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4583 (Fmake_overlay): Remove redundant tests.
4584 (fix_start_end_in_overlays): Remove redundant recentering.
4586 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4588 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4589 Update dependencies.
4591 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4593 Fix a malloc race condition involving strsignal.
4594 A signal can arrive in the middle of a malloc, and Emacs's signal
4595 handler can invoke strsignal, which can invoke malloc, which is
4596 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4597 Fix it by altering the signal handler so that it does not invoke
4599 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4600 * process.c (status_message): Use const pointer, in case strsignal
4601 is #defined to safe_strsignal.
4602 * sysdep.c (sys_siglist, init_signals): Always define and
4603 initialize a substitute sys_siglist if the system does not define
4604 one, even if HAVE_STRSIGNAL.
4605 (safe_strsignal): Rename from strsignal. Always define,
4606 using sys_siglist. Return a const pointer.
4607 * syssignal.h (safe_strsignal): New decl.
4608 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4610 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4612 * w32proc.c (timer_loop): Fix code that waits for timer
4613 expiration, to avoid high CPU usage.
4615 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4617 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4618 (sweep_weak_table): Remove redundant prototypes.
4620 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4622 * emacs.c: Move the inclusion of TERM_HEADER after including
4623 windows.h on WINDOWSNT. This avoids compilation problems with
4626 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4628 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4629 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4630 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4631 as the previous version used 'void *'.
4633 * ralloc.c (ROUNDUP): Fix last change.
4634 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4637 * w32proc.c <disable_itimers>: New static flag.
4638 (init_timers): Initialize it to zero, after creating the critical
4639 sections used by the timer threads.
4640 (term_timers): Set to 1 before deleting the critical sections.
4641 (getitimer, setitimer): If disable_itimers is non-zero, return an
4642 error indication without doing anything. Reported by Fabrice
4643 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4644 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4646 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4649 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4650 term_ntproc after all the other bookkeeping, to get timers working
4651 as long as possible.

4655 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4656 Suggested by Juri Linkov in
4657 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4659 Prefer plain 'static' to 'static inline' (Bug#12541).
4660 With static functions, modern compilers inline pretty well by
4661 themselves; advice from programmers often hurts as much as it helps.
4662 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4663 this change shrinks the text size of the Emacs executable by 1.1%
4664 without affecting CPU significantly in my benchmark.

4747 Revert the FOLLOW-SYMLINKS change for file-attributes.
4748 Doing it right would require several changes to Tramp, and there's
4749 not enough time to get that tested before the freeze today.
4750 * dired.c (directory_files_internal, Ffile_attributes):
4753 * frame.c (x_report_frame_params): Port better to wider ints.

4947 Profiler improvements: more-accurate timers, overflow checks.
4948 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4949 signal.h, setjmp.h. Include systime.h instead.
4950 (saturated_add): New function.

4957 All uses changed to store the new value.
4958 (handle_profiler_signal): Rename from sigprof_handler_1,
4959 for consistency with other handlers. Do not check whether
4960 cpu_log is a hash-table if garbage collecting, since it
4961 doesn't matter in that case.

4963 for consistency with other handlers.
4964 (setup_cpu_timer): New function, with much of what used to be in
4965 Fprofiler_cpu_start. Check for out-of-range argument.
4966 Prefer timer_settime if available, and prefer
4967 thread cputime clocks, then process cputime clocks, then
4968 monotonic clocks, to the old realtime clock. Use make_timeval
4969 to round more-correctly when falling back to setitimer.
4970 (Fprofiler_cpu_start): Use it.
4971 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4972 Don't assume that passing NULL as the 2nd argument of setitimer
4973 is the same as passing a pointer to all-zero storage.
4974 Ignore SIGPROF afterwards.
4975 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4976 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4977 non-fatal signal handlers. Ignore SIGPROF on startup.
4978 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4979 in profiler.c, since sysdep.c now uses it.
4981 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5037 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5038 Since this stuff is now private to charset.c, there's no need for
5039 a public macro and no need to inline by hand.

5077 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5078 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5080 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5082 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
5083 CHAR_STRING_ADVANCE.
5084 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5085 STRING_CHAR_ADVANCE.
5087 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5089 Move Vlibrary_cache to emacs.c and reset before dumping.
5091 * lisp.h (reset_image_types): Declare.
5092 [WINDOWSNT] (Vlibrary_cache): Declare.
5094 * image.c (reset_image_types): New function.
5096 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5097 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
5098 (Fdump_emacs): Reset Vlibrary_cache and image_types.
5100 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
5101 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5103 * w32.h (Vlibrary_cache): Do not declare.
5105 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5107 * w32proc.c (sys_signal): Handle all signals defined by the
5108 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5109 handlers for signals supported by Windows. Don't override
5110 term_ntproc as the handler for SIGABRT.
5111 (sigaction): Rewrite to call sys_signal instead of duplicating its
5113 (sys_kill): Improve commentary.
5115 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5116 consistency with a signature of a signal handler. All callers
5118 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5119 install term_ntproc as a signal handler for SIGABRT, as that
5120 should be done by the dumped Emacs.
5122 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5124 * w32select.c (term_w32select): Protect against repeated
5125 invocation by setting clipboard_owner to NULL after calling
5128 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5129 and term_ntproc to their modified signatures.
5131 * character.c (char_string, string_char): Remove calls to
5132 MAYBE_UNIFY_CHAR. See the discussion starting at
5133 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5136 2012-09-25 Chong Yidong <cyd@gnu.org>
5138 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5140 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5142 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5143 when encountering an unknown bytecode.
5145 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5147 image.c, indent.c: Use bool for booleans.
5148 * dispextern.h (struct image_type): Members valid_p, load, init
5149 now return bool, not int. All uses changed.
5150 * image.c: Omit unnecessary static decls.
5151 (x_create_bitmap_mask, x_build_heuristic_mask):
5152 Return void, not int, since callers don't care about the return value.

5181 Use bool for booleans.
5183 2012-09-24 Chong Yidong <cyd@gnu.org>
5185 * chartab.c (Fset_char_table_default): Obsolete function removed.
5187 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5189 Move pid_t related decls out of lisp.h.
5190 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5191 (interruptible_wait_for_termination):
5192 Move these decls from lisp.h to syswait.h, since they use pid_t.
5193 Needed on FreeBSD; see Herbert J. Skuhra in
5194 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5195 * callproc.c: Include syswait.h.

5213 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5214 * xfns.c (Fx_show_tip) [USE_GTK]:
5215 Use bool for boolean.
5216 * gtkutil.c (xg_update_frame_menubar):
5217 * xmenu.c (update_frame_menubar):
5218 Return void, not int, since caller ignores return value.
5219 * gtkutil.c (xg_change_toolbar_position):
5222 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5224 * makefile.w32-in (BLOCKINPUT_H): Remove.

5241 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5243 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5244 fatal_error_backtrace.
5246 * w32proc.c (sys_kill): Undo last change: don't do anything when
5247 invoked to deliver SIGABRT to our own process. This is now
5248 handled by emacs_raise.
5250 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5252 * w32term.c (w32_read_socket): Remove leftover reference to
5253 interrupt_input_pending.
5255 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5257 Do not use SA_NODEFER.
5258 Problem reported by Dani Moncayo in
5259 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5261 * sysdep.c (emacs_abort): Do not reset signal handler.
5262 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5263 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5264 wanted even on POSIXish hosts, and it doesn't work on Windows.
5266 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5268 * xterm.c (x_term_init): Call fixup_locale before and after calling
5269 gtk_init (Bug#12392).
5271 2012-09-23 Chong Yidong <cyd@gnu.org>
5273 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5274 Vdynamic_library_alist.
5276 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5277 (Fgnutls_available_p): Caller changed.
5279 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5280 (Flibxml_parse_xml_region): Likewise.
5282 * dispextern.h (struct image_type): Remove arg from init function.
5284 * image.c (Finit_image_library, lookup_image_type)
5285 (define_image_type): Remove now-unneeded second arg.
5286 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5287 (init_tiff_functions, init_gif_functions, init_svg_functions):
5288 Arglist and w32_delayed_load calling convention changed.
5289 (gs_type): Remove init_gs_functions; there is no such function.
5290 (valid_image_p, make_image): Fix caller to lookup_image_type.
5292 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5294 Simplify and avoid signal-handling races (Bug#12471).
5296 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5297 Avoid recursive loop if there's a fatal error in the function itself.
5298 * atimer.c (pending_atimers):
5299 * blockinput.h: Don't include "atimer.h"; no longer needed.
5300 (interrupt_input_pending): Remove. All uses removed.
5301 pending_signals now counts both atimers and ordinary interrupts.
5302 This is less racy than having three separate pending-signal flags.
5303 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5305 Rename from their upper-case counterparts BLOCK_INPUT,
5306 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5307 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5308 This makes it easier to access volatile variables more accurately.
5309 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5310 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5311 that's more reliable if the code is buggy and sets
5312 interrupt_input_blocked to a negative value. All uses changed.
5313 * atimer.c (deliver_alarm_signal):
5314 Remove. No need to deliver this to the parent; any thread can
5315 handle this signal now. All uses replaced by underlying handler.
5316 * atimer.c (turn_on_atimers):
5317 * dispnew.c (handle_window_change_signal):
5318 * emacs.c (handle_danger_signal):
5319 * keyboard.c (kbd_buffer_get_event):
5320 Don't reestablish signal handler; not needed with sigaction.
5321 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5323 Rework to avoid unnecessary accesses to volatile variables.
5324 (UNBLOCK_INPUT_TO): Now a function.
5325 (totally_unblock_input, unblock_input): New decls.
5326 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5327 (init_data): Remove. Necessary stuff now done in init_signal.
5328 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5329 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5330 (fatal_error_code): Remove; no longer needed.
5331 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5332 it doesn't always backtrace. All uses changed. No need to reset
5333 signal to default, since sigaction and/or die does that for us now.
5334 Use emacs_raise (FOO), not kill (getpid (), FOO).
5335 (main): Check more-accurately whether we're dumping.
5336 Move fatal-error setup to sysdep.c
5337 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5338 * gtkutil.c (xg_get_file_name, xg_get_font):
5339 Remove no-longer-needed signal-mask manipulation.
5340 * keyboard.c, process.c (POLL_FOR_INPUT):
5341 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5342 * keyboard.c (read_avail_input): Remove.
5343 All uses replaced by gobble_input.
5344 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5345 (kbd_buffer_store_event_hold, gobble_input):
5346 (record_asynch_buffer_change) [USABLE_SIGIO]:
5347 (store_user_signal_events):
5348 No need to mess with signal mask.
5349 (gobble_input): If blocking input and there are terminals, simply
5350 set pending_signals to 1 and return. All hooks changed to not
5351 worry about whether input is blocked.
5352 (process_pending_signals): Clear pending_signals before processing
5353 them, in case a signal comes in while we're processing.
5354 By convention callers now test pending_signals before calling us.
5355 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5356 New functions, to support changes to blockinput.h.
5357 (handle_input_available_signal): Now extern.
5358 (reinvoke_input_signal): Remove. All uses replaced by
5360 (quit_count): Now volatile, since a signal handler uses it.
5361 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5362 All callers changed. Block SIGINT only if not already blocked.
5363 Clear sigmask reliably, even if Fsignal returns, which it can.
5364 Omit unnecessary accesses to volatile var.
5365 (quit_throw_to_read_char): No need to restore sigmask.
5366 * keyboard.c (gobble_input, handle_user_signal):
5367 * process.c (wait_reading_process_output):
5368 Call signal-handling code rather than killing ourselves.
5369 * lisp.h: Include <float.h>, for...
5370 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5371 (pending_signals): Now volatile.
5372 (syms_of_data): Now const if IEEE floating point.
5373 (handle_input_available_signal) [USABLE_SIGIO]:
5374 (terminate_due_to_signal, record_child_status_change): New decls.
5375 * process.c (create_process): Avoid disaster if memory is exhausted
5376 while we're processing a vfork, by tightening the critical section
5378 (send_process_frame, process_sent_to, handle_pipe_signal)
5379 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5381 (send_process): No need for setjmp/longjmp any more, since the
5382 SIGPIPE stuff is now gone. Instead, report an error if errno
5384 (record_child_status_change): Now extern. PID and W are now args.
5385 Return void, not bool. All callers changed.
5386 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5387 Remove. All uses removed. This bug should be fixed now in a
5389 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5390 and record the child status change directly. This avoids the
5391 need to futz with the signal mask.
5392 (process_fatal_action): Move here from emacs.c.
5393 (emacs_sigaction_flags): New function, containing
5394 much of what used to be in emacs_sigaction_init.
5395 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5396 caught by emacs, to make races less likely.
5397 (deliver_process_signal): Rename from handle_on_main_thread.
5399 (BACKTRACE_LIMIT_MAX): Now at top level.
5400 (thread_backtrace_buffer, threadback_backtrace_pointers):
5402 (deliver_thread_signal, deliver_fatal_thread_signal):
5403 New functions, for more-accurate delivery of thread-specific signals.
5404 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5405 (deliver_arith_signal): Handle in this thread, not
5406 in the main thread, since it's triggered by this thread.
5407 (maybe_fatal_sig): New function.
5408 (init_signals): New arg DUMPING so that we can be more accurate
5409 about whether we're dumping. Caller changed.
5410 Treat thread-specific signals differently from process-general signals.
5411 Block all signals while handling fatal error; that's safer.
5412 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5414 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5415 Ignore SIGPIPE unless batch.
5416 (emacs_backtrace): Output backtrace for the appropriate thread,
5417 which is not necessarily the main thread.
5418 * syssignal.h: Include <stdbool.h>.
5419 (emacs_raise): New macro.
5420 * xterm.c (x_connection_signal): Remove; no longer needed
5421 now that we use sigaction.
5422 (x_connection_closed): No need to mess with sigmask now.
5423 (x_initialize): No need to reset SIGPIPE handler here, since
5424 init_signals does this for us now.
5426 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5428 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5429 background rect may be larger (Bug#12245).
5431 2012-09-23 Chong Yidong <cyd@gnu.org>
5433 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5435 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5437 * .gdbinit: Just stop at fatal_error_backtrace.
5438 See Stefan Monnier's request in
5439 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5440 Remove no-longer-used query of system type.
5442 2012-09-22 Chong Yidong <cyd@gnu.org>
5444 * search.c (Freplace_match): Doc fix (Bug#12325).
5446 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5448 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5449 (Fline_end_position): Doc fix.
5451 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5453 2012-09-22 Chong Yidong <cyd@gnu.org>
5455 * dispextern.h (struct image_type): Add new slot, storing a type
5456 initialization function.
5458 * image.c (define_image_type): Call the image initializer function
5459 if it is defined. Arguments and return value changed.
5460 (valid_image_p, make_image): Callers changed.
5461 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5462 (gif_type, imagemagick_type, svg_type, gs_type):
5463 Add initialization functions.
5464 (Finit_image_library): Call lookup_image_type.
5465 (CHECK_LIB_AVAILABLE): Macro deleted.
5466 (lookup_image_type): Call define_image_type here, rather than via
5467 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5468 (syms_of_image): Move define_image_type calls for xbm_type and
5469 pbm_type to lookup_image_type.
5471 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5473 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5474 'idle_timers' from here ...
5475 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5476 lists, to avoid infloops when the timer does something stupid,
5477 like reinvoke itself with the same or smaller time-out.
5480 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5482 * window.c (Fsplit_window_internal): Handle only Qt value of
5483 Vwindow_combination_limit separately.
5484 (Qtemp_buffer_resize): New symbol.
5485 (Vwindow_combination_limit): New default value.
5488 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5490 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5491 the new overlay string. (Bug#10159)
5493 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5495 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5496 or that fprintf is async-signal-safe. POSIX doesn't require
5499 2012-09-22 Chong Yidong <cyd@gnu.org>
5501 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5504 2012-09-22 Kenichi Handa <handa@gnu.org>
5506 * composite.c (composition_reseat_it): Handle the case that a
5507 grapheme cluster is not covered by a single font (Bug#12352).
5509 2012-09-21 Chong Yidong <cyd@gnu.org>
5511 * image.c (define_image_type): Avoid adding duplicate types to
5512 image_types (Bug#12463). Suggested by Jörg Walter.
5514 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5516 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5517 (print_load_command_name): Add case LC_DATA_IN_CODE.
5518 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5520 2012-09-21 Glenn Morris <rgm@gnu.org>
5522 * eval.c (Frun_hook_with_args_until_success)
5523 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5525 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5527 * fileio.c (Ffile_selinux_context): Only call freecon when
5528 lgetfilecon succeeded.
5529 (Fset_file_selinux_context): Likewise. (Bug#12444)
5531 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5533 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5534 reordering, locate the cursor by calling set_cursor_from_row; if
5535 that fails, clear the desired glyph matrix before returning a
5536 failure indication to the caller. Fixes leaving garbled display
5537 when fast scrolling with a down-key. (Bug#12403)
5538 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5539 scrolling through multibyte text.
5541 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5543 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5544 calling mark_vectorlike since that's the one that marks the window.
5545 (mark_discard_killed_buffers): Mark the final cdr.
5546 * window.h (struct window): Move prev/next_buffers to the
5547 non-standard fields.
5548 * window.c (make_window): Initialize prev/next_buffers manually.
5550 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5552 Omit unused arg EXPECTED from socket hooks.
5553 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5554 * nsterm.m (ns_term_init):
5555 * termhooks.h (struct terminal.read_socket_hook):
5556 * w32inevt.c (w32_console_read_socket):
5557 * w32term.c (w32_read_socket):
5558 * xterm.c (XTread_socket):
5559 Omit unused arg EXPECTED. All callers changed.
5560 (store_user_signal_events): Return void, not int, since callers no
5561 longer care about the return value. All uses changed.
5563 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5565 * w32gui.h (XParseGeometry): Do not declare.
5567 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5569 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5570 Ignore 'expected'. See Eli Zaretskii in
5571 <http://bugs.gnu.org/12471#8> (last line).
5573 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5574 (XParseGeometry): Now static. Substitute extremal values for
5575 values that are out of range.
5577 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5579 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5581 * nsfns.m (XParseGeometry): Remove.
5582 (Fx_create_frame): Call x_set_offset to correctly interpret
5583 top_pos in geometry.
5585 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5586 (Fx_parse_geometry): If there is a space in string, call
5587 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5589 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5591 * search.c (scan_buffer): Use character positions in calls to
5592 region_cache_forward and region_cache_backward, not byte
5593 positions. (Bug#12196)
5595 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5596 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5598 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5599 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5600 emacs_blocked_malloc, now deleted.
5602 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5604 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5605 The workaround was for improving performance on Solaris 2.4, but
5606 is getting in the way now. Emacs will still work if someone is
5607 still running Solaris 2.4 in a museum somewhere; Sun dropped
5608 support for Solaris 2.4 in 2003.
5609 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5610 * process.c (create_process) [HAVE_WORKING_VFORK]:
5611 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5612 since Emacs no longer uses vfork on that platform.
5614 2012-09-17 Glenn Morris <rgm@gnu.org>
5616 * emacs.c: Use COPYRIGHT.
5618 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5620 Remove configure's --without-sync-input option (Bug#12450).
5621 When auditing signal-handling in preparation for cleaning it up,
5622 I found that SYNC_INPUT has race conditions and would be a real
5623 pain to fix. Since it's an undocumented and deprecated
5624 configure-time option, now seems like a good time to remove it.
5625 Also see <http://bugs.gnu.org/11080#16>.
5626 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5627 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5628 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5629 (malloc_hysteresis):
5630 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5631 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5632 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5633 (dont_register_blocks, bytes_used_when_reconsidered)
5634 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5635 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5636 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5637 Remove. All uses removed.
5638 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5639 implementation, one that depends on whether the new macro
5640 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5642 * atimer.c (run_timers, handle_alarm_signal):
5643 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5644 (handle_async_input, process_pending_signals)
5645 (handle_input_available_signal, init_keyboard):
5646 * nsterm.m (ns_read_socket):
5647 * process.c (wait_reading_process_output):
5648 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5649 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5651 * xterm.c (XTread_socket):
5653 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5654 * eval.c (handling_signal): Remove. All uses removed.
5655 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5656 All uses replaced with the SYNC_INPUT version.
5657 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5659 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5662 * font.c (Ffont_shape_gstring): Remove unused local.
5664 2012-09-16 Glenn Morris <rgm@gnu.org>
5666 * Makefile.in (clean): No longer run nextstep's clean.
5668 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5670 (ns-app): Move here from ns.mk, and simplify.
5671 (clean): Simplify nextstep entry.
5672 * ns.mk: Remove file.
5674 2012-09-17 Kenichi Handa <handa@gnu.org>
5676 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5677 not covert the last few charactes.
5679 2012-09-16 Kenichi Handa <handa@gnu.org>
5681 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5682 here, but just check the validity of glyphs in the glyph-string.
5684 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5686 * window.c (Fwindow_parameter, Fset_window_parameter):
5687 Accept any window as argument (Bug#12452).
5689 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5691 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5692 to ns_term_init to avoid memory leak.
5694 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5695 explicit retain/release.
5696 (ns_term_init): Only allow one display. Initialize outerpool and
5699 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5701 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5702 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5703 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5704 the Microsoft problem in a different way, by altering ../nt/config.nt.
5706 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5721 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5722 by lisp.h. This completes removal of setjmp.h inclusion
5723 erroneously announced in the previous commit. (Bug#12446)
5725 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5728 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5729 not defined as a macro. The latter happens on MS-Windows.
5732 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5734 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5735 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5736 Some instances of '#include <setjmp.h>' removed, if the
5737 only reason for the instance was because "lisp.h" was included.
5738 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5739 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5740 and _longjmp with the new symbols. Emacs already uses _setjmp if
5741 available, so this change affects only POSIXish hosts that have
5742 sigsetjmp but not _setjmp, such as some versions of Solaris and
5743 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5744 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5745 (png_load_body) [HAVE_PNG]:
5746 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5747 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5748 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5749 since PNG requires jmp_buf. This is the only exception to the
5750 general rule that we now use sys_setjmp and sys_longjmp.
5751 This exception is OK since this code does not change the signal
5752 mask or longjmp out of a signal handler.
5754 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5756 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5757 Include "syssignal.h", for 'main_thread'.
5759 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5761 Avoid out-of-range marker position (Bug#12426).
5762 * insdel.c (replace_range, replace_range_2):
5763 Adjust markers before overlays, as suggested by comments.
5764 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5765 Remove redundant check before calling offset_intervals.
5767 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5769 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5770 current buffer (Bug#12387).
5772 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5774 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5776 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5778 Use a more backwards-compatible timer format (Bug#12430).
5779 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5780 vector element, not from the 4th, since PSECS is now at the end.
5781 (Fcurrent_idle_time): Doc fix.
5783 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5785 Function to mark objects and remove killed buffers at once.
5786 * alloc.c (discard_killed_buffers): Rename to ...
5787 (mark_discard_killed buffers) ... new name. Add marking
5788 of remaining objects. Fix comment. Adjust users.
5789 (mark_object): Do not touch frame buffer lists here.
5790 * frame.c (delete_frame): Reset frame buffer lists here.
5792 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5794 Better workaround for GNOME bug when --enable-gcc-warnings.
5795 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5796 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5797 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5799 Simplify SIGIO usage (Bug#12408).
5800 The code that dealt with SIGIO was crufty and confusing, e.g., it
5801 played tricks like "#undef SIGIO" but these tricks were not used
5802 consistently. Simplify mostly by not #undeffing standard symbols,
5803 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5804 or not as we please) rather than "defined SIGIO" (standard symbol
5805 that we probably shouldn't #undef).
5806 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5807 Modules that need it can include it.
5808 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5809 * dispextern.h (ignore_sigio): New decl.
5810 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5811 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5812 * emacs.c (shut_down_emacs):
5813 * keyboard.c (kbd_buffer_store_event_hold):
5814 Use ignore_sigio rather than invoking 'signal' directly.
5815 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5817 (FIONREAD, SIGIO): Do not #undef.
5818 (tty_read_avail_input): Use #error rather than a syntax error.
5819 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5820 for I_PIPE, used by SETUP_SLAVE_PTY.
5821 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5822 * sysdep.c (croak): Remove; no longer needed. This bit of
5823 temporary code, with Fred N. Fish's comment that it's temporary,
5824 has been in Emacs since at least 1992!
5825 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5826 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5827 * syssignal.h (croak): Remove decl.
5828 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5829 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5830 now that we're termios-only.
5831 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5832 * term.c (dissociate_if_controlling_tty): Use #error rather than
5835 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5836 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5837 to work around GNOME bug 683906.
5838 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5839 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5840 This works around GCC bug 54561.
5842 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5844 More fixes for 'volatile' and setjmp/longjmp.
5845 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5846 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5847 (png_load_body) [HAVE_PNG]:
5848 (jpeg_load_body) [HAVE_JPEG]:
5849 New function, with most of the old parent function's body.
5850 (png_load) [HAVE_PNG]:
5851 (jpeg_load) [HAVE_JPEG]:
5852 Invoke the new function, to avoid longjmp munging our locals.
5853 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5854 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5855 longjmp is passed 2, as the C standard doesn't guarantee this.
5856 Instead, store the failure code into mgr->failure_code.
5858 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5860 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5861 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5862 (syms_of_keyboard): Remove support for unread-command-char.
5864 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5866 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5867 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5868 violation. (Bug#12426)
5870 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5872 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5874 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5876 * eval.c: Add `inhibit-debugger'.
5877 (Qinhibit_debugger): New symbol.
5878 (call_debugger): Bind it instead of Qdebug_on_error.
5879 (maybe_call_debugger): Test Vinhibit_debugger.
5880 (syms_of_eval): Define inhibit-debugger.
5881 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5882 (syms_of_xdisp): Remove inhibit-debug-on-message.
5884 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5886 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5887 If a nonvolatile local variable is written before a _longjmp to
5888 the frame containing the variable, and is read after the _longjmp,
5889 the value read is indeterminate. Some local variables of type
5890 'struct handler' and 'struct catchtag' are used in this way, so
5891 mark each of their slots as volatile if the slot can be set before
5892 _longjmp and read afterwards.
5893 * lisp.h (struct handler): var and chosen_clause are now volatile.
5894 (struct catchtag): val, next, and pdlcount are now volatile.
5896 * bidi.c (bidi_push_it, bidi_pop_it):
5897 * fns.c (copy_hash_table):
5898 * image.c (define_image_type):
5899 * keyboard.c (kbd_buffer_store_event_hold):
5900 * process.c (Fprocess_send_eof):
5901 * xfaces.c (x_create_gc) [HAVE_NS]:
5902 * xgselect.c (xg_select):
5903 Prefer assignment to memcpy when either will do.
5905 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5906 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5907 time an item is removed. No need to mark this function 'inline';
5908 the compiler knows better than we do.
5910 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5912 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5913 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5914 to change_frame_size (Bug#12388).
5915 (windowDidResize:): Pass YES to updateFrameSize.
5917 * nsterm.h: Add delay parameter to updateFrameSize.
5919 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5921 Discard killed buffers from deleted window and frame objects.
5922 This reduces an amount of references to killed buffers and
5923 helps GC to reclaim them faster.
5924 * alloc.c (discard_killed_buffers): New function.
5925 (mark_object): Use it for deleted windows and frames.
5926 (mark_object): If symbol's value is set up for a killed buffer
5927 or deleted frame, restore its global binding.
5928 * data.c (swap_in_global_binding): Add GC notice.
5929 (swap_in_symval_forwarding): Use convenient set_blv_where.
5930 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5931 * window.h: ... to here.
5933 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5935 Convenient macro to check whether the buffer is live.
5936 * buffer.h (BUFFER_LIVE_P): New macro.
5937 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5938 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5940 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5942 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5943 composition cases (Bug#12364).
5945 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5946 overhang of succeeding glyphs overlapping box cursor.
5948 * w32term.c (x_draw_glyph_string): Likewise.
5950 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5952 Simplify, document, and port floating-point (Bug#12381).
5953 The porting part of this patch fixes bugs on non-IEEE platforms
5954 with frexp, ldexp, logb.
5955 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5957 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5958 support, by removing commented-out code and briefly listing the
5959 C89 functions excluded. The commented-out stuff was confusing
5960 maintenance, e.g., we thought we needed cbrt but it was commented out.
5961 (logb): Remove decl; no longer needed.
5962 (isfinite): New macro, if not already supplied.
5963 (isnan): Don't replace any existing macro.
5964 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5965 are present on all C89 platforms.
5966 (Ffrexp): Do not special-case zero, as frexp does the right thing
5968 (Flogb): Do not use logb, as it doesn't have the desired meaning
5969 on hosts that use non-base-2 floating point. Instead, stick with
5970 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5971 frexp, to avoid getting an unspecified result.
5973 * xdisp.c (Qinhibit_debug_on_message): Now static.
5975 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5977 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5978 NSBezierPath (Bug#12131).
5980 2012-09-10 Chong Yidong <cyd@gnu.org>
5982 * fns.c (Fdelq, Fdelete): Doc fix.
5984 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5986 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5987 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5989 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5991 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5992 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5995 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5997 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5998 left fringe if the window has a left margin. This avoids leaving
5999 traces of the cursor because its leftmost pixel is not drawn over.
6001 * dispnew.c (update_window_line): When the left margin area of a
6002 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6003 that screen line. (Bug#12277)
6005 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6007 Assume C89 or later for math functions (Bug#12381).
6008 This simplifies the code, and makes it a bit smaller and faster,
6009 and (most important) makes it easier to clean up signal handling
6010 since we can stop worring about floating-point exceptions in
6011 library code. That was a problem before C89, but the problem
6012 went away many years ago on all practical Emacs targets.
6013 * data.c, image.c, lread.c, print.c:
6014 Don't include <math.h>; no longer needed.
6015 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6016 might be autoconfigured, as that never happens.
6018 * doprnt.c (DBL_MAX_10_EXP):
6019 * print.c (DBL_DIG):
6020 Remove. C89 or later always defines these.
6021 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6022 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6023 (arith_error, domain_error, domain_error2):
6024 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6025 no longer needed -- we simply return what C returns. All uses removed.
6026 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6028 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6029 Remove. All uses expanded, as these macros are no longer used
6030 more than once and are now more trouble than they're worth.
6031 (Ftan): Use tan, not sin / cos.
6032 (Flogb): Assume C89 frexp.
6033 (fmod_float): Assume C89 fmod.
6034 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6035 (init_floatfns): Remove. All uses removed.
6037 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6039 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6040 compositeToPoint for OSX < 10.6 (Bug#12390).
6042 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6044 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6045 This produces more-accurate results.
6047 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6049 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6050 changes (Bug#12088).
6052 2012-09-08 Chong Yidong <cyd@gnu.org>
6054 * syntax.c (Fstring_to_syntax): Doc fix.
6056 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6058 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6059 in the internal border.
6060 (x_set_window_size): Remove static variables and their usage.
6061 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6062 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6063 Remove fringe/internal border adjustment (Bug#11052).
6064 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6065 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6066 (ns_fix_rect_ibw): Remove.
6067 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6068 (ns_dumpglyphs_box_or_relief): Ditto.
6069 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6071 (ns_dumpglyphs_image): Ditto.
6072 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6074 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6075 their usage. Add fringe_extended_p and its use as in other terms.
6076 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6077 scroll bar was removed.
6078 (updateFrameSize): New function.
6079 (windowDidResize): Move code to updateFrameSize and call it.
6081 * nsterm.h (EmacsView): Add updateFrameSize.
6083 2012-09-07 Chong Yidong <cyd@gnu.org>
6085 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6087 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6089 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6091 More signal-handler cleanup (Bug#12327).
6092 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6093 Problem introduced when merging patches. Noted by Eli Zaretskii in
6094 <http://bugs.gnu.org/12327#67>.
6095 * floatfns.c: Comment fix.
6096 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6097 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6098 and anyway the declaration is harmless even if SIGDANGER is not defined.
6099 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6100 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6101 source files not surprisingly expected syssignal.h to define, or
6102 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6103 Include <sys/ioctl.h>, for FIONREAD.
6104 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6105 This eliminates a problem whereby other files mysteriously had
6106 to include "syssignal.h" before including "systty.h" if they
6107 wanted to use "#ifdef SIGIO".
6109 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6111 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6113 * w32.c (sigemptyset): Empty the set.
6114 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6116 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6118 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6120 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6121 (mark_object): Likewise for frame objects.
6123 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6125 * syssignal.h (handle_on_main_thread): Always declare,
6126 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6127 This ports to platforms without HAVE_PTHREAD.
6129 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6131 Signal-handler cleanup (Bug#12327).
6132 Emacs's signal handlers were written in the old 4.2BSD style with
6133 sigblock and sigmask and so forth, and this led to some
6134 inefficiencies and confusion. Rewrite these to use
6135 pthread_sigmask etc. without copying signal sets around. Also,
6136 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6137 'signal', and instead use functions that do not attempt to take
6138 over the system name space. This patch causes Emacs's text
6139 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6140 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6141 Do not include <signal.h> or "syssignal.h", as these
6142 modules do not use signals.
6143 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6144 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6145 Do not include <signal.h>, as "syssignal.h" does that for us now.
6146 * atimer.c (sigmask_atimers): New function.
6147 (block_atimers, unblock_atimers): New functions,
6148 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6150 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6151 no longer needed here.
6152 * emacs.c (main): Inspect existing signal handler with sigaction,
6153 so that there's no need to block and unblock SIGHUP.
6154 * sysdep.c (struct save_signal): New member 'action', replacing
6155 old member 'handler'.
6156 (save_signal_handlers, restore_signal_handlers):
6157 Use sigaction instead of 'signal' to save and restore.
6158 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6159 New function. All users of 'signal' modified to use set_sighandler
6160 if they're writeonly, and to use sys_signal if they're read+write.
6161 (emacs_sigaction_init, forwarded_signal): New functions.
6162 (sys_signal): Remove. All uses replaced by calls to sigaction
6163 and emacs_sigaction_init, or by direct calls to 'signal'.
6164 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6165 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6166 all uses replaced by pthread_sigmask etc. calls.
6167 * syssignal.h: Include <signal.h>.
6168 (emacs_sigaction_init, forwarded_signal): New decls.
6169 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6170 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6171 (sigmask, sys_sigmask): Remove; no longer needed.
6172 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6173 (sigblock, sigunblock, sigfree):
6174 (sigsetmask) [!defined sigsetmask]:
6175 Remove. All uses replaced by pthread_sigmask.
6176 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6177 no longer need to be replaced, and its typical old uses
6178 are now done via emacs_sigaction_init and sigaction.
6179 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6180 (sys_sigdel): Remove; unused.
6181 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6183 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6185 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6186 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6188 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6190 Explicitly mark buffer_defaults and buffer_local_symbols.
6191 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6192 mark_local_symbols here.
6193 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6194 since special buffers aren't marked here any more.
6195 (allocate_buffer): Chain new buffer with all_buffers here...
6196 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6198 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6199 (syms_of_buffer): Remove staticpro of the above.
6200 (init_buffer_once): Set names for buffer_defaults and
6201 buffer_local_symbols.
6203 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6205 Use bool for booleans in font-related modules.
6206 * font.c (font_intern_prop, font_style_to_value)
6207 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6208 (generate_otf_features, font_check_otf_features, font_check_otf)
6209 (font_match_p, font_list_entities, font_at):
6210 * fontset.c (fontset_id_valid_p, reorder_font_vector
6211 (fontset_find_font, Fset_fontset_font)
6212 (face_suitable_for_char_p) [0]:
6213 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6214 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6215 (m17n_flt_initialized, ftfont_shape_by_flt):
6216 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6217 * nsfont.m (nsfont_draw):
6218 * w32font.c (w32font_draw):
6219 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6220 Use bool for booleans.
6221 * font.h: Adjust to above API changes.
6222 (struct font, struct font_driver, struct font_driver_list):
6223 Use bool for booleans.
6224 (struct font): Remove useless member encoding_type.
6226 * fontset.c, xftfont.c: Omit unnecessary static decls.
6228 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6230 * alloc.c (mark_object): Revert window marking code
6231 since it's unsafe for the Fset_window_configuration.
6233 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6235 Fix race conditions with signal handlers and errno (Bug#12327).
6236 Be more systematic about preserving errno whenever a signal
6237 handler returns, even if it's not in the main thread. Do this by
6238 renaming signal handlers to distinguish between signal delivery
6239 and signal handling. All uses changed.
6240 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6241 * data.c (deliver_arith_signal): Rename from arith_error.
6242 * dispnew.c (deliver_window_change_signal): Rename from
6243 window_change_signal.
6244 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6245 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6246 * keyboard.c (deliver_input_available_signal): Rename from
6247 input_available_signal.
6248 (deliver_user_signal): Rename from handle_user_signal.
6249 (deliver_interrupt_signal): Rename from interrupt_signal.
6250 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6251 (deliver_child_signal): Rename from sigchld_handler.
6252 * atimer.c (handle_alarm_signal):
6253 * data.c (handle_arith_signal):
6254 * dispnew.c (handle_window_change_signal):
6255 * emacs.c (handle_fatal_signal, handle_danger_signal):
6256 * keyboard.c (handle_input_available_signal):
6257 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6258 * process.c (handle_pipe_signal, handle_child_signal):
6259 New functions, with the actual signal-handling code taken from the
6260 original respective signal handlers, sans the sporadic attempts to
6261 preserve errno, since that's now done by handle_on_main_thread.
6262 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6263 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6264 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6266 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6267 Move initialization of main_thread to sysdep.c's init_signals.
6268 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6269 our usage, and simplifies the mainline code.
6270 (record_child_status_change): New static function, as a helper
6271 for handle_child_signal, and with most of the old child handler's
6273 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6274 (handle_child_signal): Use the above.
6275 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6276 Moved here from emacs.c.
6277 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6278 code moved here from emacs.c's main function.
6279 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6280 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6281 This lets callers save and restore errno properly.
6283 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6285 Remove redundant or unused things here and there.
6286 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6287 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6288 * editfns.c (Fcompare_buffer_substrings): Likewise.
6289 * frame.h (struct terminal, struct font_driver_list):
6290 Remove redundant declarations.
6291 * window.h (Qleft, Qright): Likewise.
6293 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6295 Do not mark objects from deleted buffers, windows and frames.
6296 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6297 (mark_object): Likewise for windows and frames.
6299 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6301 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6302 buffer_defaults and buffer_local_symbols as valid objects.
6303 Return special value to denote them.
6305 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6307 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6308 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6309 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6310 (file_name_absolute_p, Fsubstitute_in_file_name):
6311 (check_executable, check_writable, Ffile_accessible_directory_p)
6312 (Fset_file_selinux_context, Fdefault_file_modes)
6313 (Finsert_file_contents, choose_write_coding_system)
6314 (Fwrite_region, build_annotations, a_write, e_write)
6316 * filelock.c (boot_time_initialized, get_boot_time)
6317 (get_boot_time_1, lock_file_1, within_one_second):
6318 * floatfns.c (in_float):
6319 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6320 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6321 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6322 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6323 * window.c (compare_window_configurations):
6324 Use bool for booleans.
6325 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6326 (Fdefault_file_modes): Now mode_t, not int, for modes.
6327 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6328 (internal_delete_file): Now returns void, not a (boolean) int,
6329 since nobody was looking at the return value.
6330 * lisp.h, window.h: Adjust to above API changes.
6332 * xdisp.c (set_message): Simplify and reindent last change.
6334 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6336 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6338 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6340 * eval.c (call_debugger): Make the function non-static so that we
6341 can call it from set_message.
6343 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6344 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6346 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6348 Give more-useful info on a fatal error (Bug#12328).
6349 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6350 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6351 of doing the work ourselves.
6352 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6353 do most of the work.
6354 (fatal_error_backtrace): New function, taken from the guts
6355 of the old fatal_error_signal, but with a new option to output
6357 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6358 info about the signal than just its number.
6359 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6360 * sysdep.c: Include <execinfo.h>
6361 (emacs_backtrace): New function, taken partly from the previous
6362 code of the 'die' function.
6363 (emacs_abort): Call fatal_error_backtrace rather than abort.
6365 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6367 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6368 eager (load-time) macro-expansion.
6369 * lisp.mk (lisp): Add macroexp.
6371 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6373 Simplify redefinition of 'abort' (Bug#12316).
6374 Do not try to redefine the 'abort' function. Instead, redo
6375 the code so that it calls 'emacs_abort' rather than 'abort'.
6376 This removes the need for the NO_ABORT configure-time macro
6377 and makes it easier to change the abort code to do a backtrace.
6378 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6379 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6380 Remove; sysdep.c's emacs_abort now takes its place.
6381 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6382 'abort' changed to use 'emacs_abort'.
6383 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6384 (abort) [!defined abort]: Rename to ...
6385 (emacs_abort): ... new name.
6386 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6387 the place of the old 'abort' in emacs.c.
6388 * w32.c, w32fns.c (abort): Do not #undef.
6389 * w32.c (emacs_abort): Rename from w32_abort.
6391 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6393 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6394 offsets[j].dv, since the y axis of the screen coordinates points
6395 down, while the y axis of the font definition coordinates points
6396 up. This fixes display of Arabic diacritics such as KASRA and
6397 KASRATAN. (Bug#11860)
6399 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6401 Be more systematic about _setjmp vs setjmp.
6402 * alloc.c (test_setjmp, mark_stack):
6403 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6404 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6405 (png_load, my_error_exit, jpeg_load):
6406 * process.c (send_process_trap, send_process):
6407 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6408 The underscored versions are up to 30x faster on some hosts.
6409 Formerly, the code used setjmp+longjmp sometimes and
6410 _setjmp+_longjmp at other times, with no particular reason to
6411 prefer setjmp+longjmp.
6413 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>

6443 * dispextern.h, lisp.h: Reflect above API changes.
6444 * firstfile.c (dummy): Use the address of 'main', whose signature
6445 won't change, instead of the address of 'initialize', whose
6446 signature just changed from int to bool.
6447 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6448 * msdos.c (fatal_error_in_progress): ... from here.
6449 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6451 (redisplay_internal, unwind_redisplay): Simply clear
6452 REDISPLAYING_P when unwinding, instead of saving its previous,
6453 always-false value and then restoring it.
6455 Clean up some extern decls.
6456 Mostly, this hoists extern decls out of .c files and into .h files.
6457 That way, we're more likely to catch errors if the interfaces change.
6458 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6459 declare xg_mark_data.
6460 * dispextern.h (x_frame_parm_handlers):

6480 Remove now-redundant extern decls.
6481 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6482 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6484 * xfaces.c: Remove unnecessary static decls.
6485 * xterm.c (updating_frame): Remove decl of nonexistent object.
6487 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6488 when building globals.h, as the objects that are not built on
6489 this host are not needed to compile C files on this host.
6491 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6493 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6541 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6543 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6544 more than one grapheme cluster passed to the shaper: compute the
6545 offset adjustment values separately for each cluster. (Bug#11860)
6547 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6548 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6549 about implicit conversions from integer to pointer.
6551 2012-09-01 Daniel Colascione <dancol@dancol.org>
6553 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6554 system used too early.
6556 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

6607 window system declarations.
6609 * frame.h: Move common functions here: set_frame_menubar,
6610 x_set_window_size, x_sync, x_get_focus_frame,
6611 x_set_mouse_position, x_set_mouse_pixel_position,
6612 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6639 * lisp.h (mark_ttys): Remove prototype.
6640 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

6673 * lread.c (init_lread): For out-of-tree builds, only add the
6674 source directory's site-lisp dir to the load-path if it exists,

6696 Handle click on close button as quit.
6698 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6699 Add window_closed and button_values. Add void as return value for
6700 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6701 Add process_dialog as new member.
6703 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6705 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

6835 (code_convert_string, code_convert_string_norecord)
6836 (Fset_coding_system_priority):
6837 * fileio.c (Finsert_file_contents):
6838 Use bool for booleans.
6839 * coding.h, lisp.h: Reflect above API changes.
6840 * coding.c: Remove unnecessary static function decls.
6841 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6842 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6843 not a boolean 'int', since callers never look at the return value.
6844 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6845 * coding.h (decoding_buffer_size, encoding_buffer_size)
6846 (emacs_mule_string_char): Remove unused extern decls.
6847 (struct iso_2022_spec, struct coding_system):
6848 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6849 (struct emacs_mule_spec): Remove unused field 'full_support'.
6850 All initializations removed.
6851 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6853 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6855 Fix spare memory change (Bug#12286).
6856 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6857 (valid_lisp_object_p): Likewise.
6859 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6861 * window.c (Fset_window_configuration): Record any window's old
6862 buffer if it's replaced (see Bug#8789). If the new current
6863 buffer doesn't appear in the selected window, go to its old
6866 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6868 Special MEM_TYPE_SPARE to denote reserved memory.
6869 * alloc.c (enum mem_type): New memory type.
6870 (refill_memory_reserve): Use new type for spare memory.
6871 This prevents live_cons_p and live_string_p from incorrect
6872 detection of uninitialized objects from spare memory as live.
6874 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6877 * Makefile.in (.PHONY): versioclean -> versionclean.
6879 Remove unused external symbols.
6880 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6881 * window.c (Qwindow_valid_p, decode_valid_window):
6882 Now static, not extern.
6883 * data.c (Qinterval): Remove; unused.
6884 (syms_of_data): Do not define 'interval'.
6885 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6886 * window.h (decode_valid_window):
6889 * character.c, charset.c, chartab.c: Use bool for booleans.
6890 * character.c (lisp_string_width, string_count_byte8)
6891 (string_escape_byte8):
6892 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6893 (load_charset_map_from_file, map_charset_chars)
6894 (Fdefine_charset_internal, define_charset_internal)
6895 (Fdeclare_equiv_charset, find_charsets_in_text)
6896 (Ffind_charset_region, char_charset, Fiso_charset):
6897 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6898 (sub_char_table_set, sub_char_table_set_range)
6899 (char_table_set_range, optimize_sub_char_table)
6900 (map_sub_char_table):
6901 Use bool for boolean.
6902 * character.c (str_to_unibyte): Omit last boolean argument; it was
6903 always 0. All callers changed.
6904 * character.h, charset.h: Adjust to match previous changes.
6905 * character.h (char_printable_p): Remove decl of nonexistent function.
6906 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6907 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6908 are all boolean, so make them single-bit bitfields.
6910 * lisp.h (ASET): Remove attempt to detect side effects.
6911 It was meant to be temporary and it often doesn't work,
6912 because when IDX has side effects the behavior of IDX==IDX
6913 is undefined. See Stefan Monnier in
6914 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6916 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6918 * lisp.h (functionp): New function (extracted from Ffunctionp).
6919 (FUNCTIONP): Use it.
6920 * eval.c (Ffunctionp): Use it.
6922 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6924 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6925 as that's faster and simpler than static storage. Don't bother
6926 with the g_main_context_query overhead if g_main_context_pending
6927 says no events are pending.
6928 (gfds, gfds_size): Remove these static vars.
6929 (xgselect_initialize): Remove; no longer needed.
6930 All uses and decls removed.
6932 * emacs.c (fatal_error_signal_hook): Remove.
6933 All uses removed. This leftover from old code was always 0.
6935 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6936 * casefiddle.c (casify_object, casify_region):
6937 * casetab.c (set_case_table):
6938 * category.c, category.h (word_boundary_p):
6939 * category.h (CHAR_HAS_CATEGORY):
6940 Use bool for booleans, instead of int.
6942 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6944 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6946 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6948 On assertion failure, print backtrace if available.
6949 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6950 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6951 * Makefile.in (LIB_EXECINFO): New macro.
6954 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6955 * bytecode.c (exec_byte_code):
6956 * callint.c (check_mark, Fcall_interactively):
6957 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6958 (getenv_internal, sync_process_alive, call_process_exited):
6959 * lisp.h (USE_SAFE_ALLOCA):
6960 Use bool for booleans, instead of int.
6961 * lisp.h, process.h: Adjust prototypes to match above changes.
6962 * callint.c (Fcall_interactively): Don't assume the mark's
6963 offset fits in 'int'.
6965 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6967 * buffer.c, buffer.h: Use bool for boolean.
6968 * buffer.c (reset_buffer_local_variables)
6969 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6970 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6971 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6972 (overlay_touches_p, overlay_strings, Foverlay_put)
6973 (report_overlay_modification, call_overlay_mod_hooks):
6974 (mmap_enlarge, mmap_set_vars):
6975 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6976 Use bool for booleans, instead of int.
6977 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6978 since the 1-or-0 return value is always ignored anyway.
6979 (mmap_initialized_p):
6980 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6981 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6983 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6985 * bidi.c: Use bool for boolean.
6986 This is a bit more readable, and makes the text segment of bidi.o
6987 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6988 Presumably it's faster too.
6989 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6991 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6992 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6993 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6994 (bidi_explicit_dir_char, bidi_level_of_next_char)
6995 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6996 Use bool for booleans, instead of int.
6997 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6998 (bidi_unshelve_cache): Adjust decls to match code.
7000 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7002 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7005 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7007 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7008 * atimer.h: Include <stdbool.h>.
7010 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7012 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7013 compile time tests instead of run time tests on systems that do
7015 (FRAME_MAC_P): Remove leftover from deleted code.
7016 * frame.c (syms_of_frame): Remove leftover from deleted code.
7018 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7020 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7022 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7024 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7025 Otherwise, the compiler complains about (A?B:C) where B is void
7026 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7027 (fontset_add): Return void, for FONTSET_ADD.
7029 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7031 * alloc.c: Use bool for booleans.
7032 (gc_in_progress, abort_on_gc)
7033 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7034 (dont_register_blocks) [GC_MALLOC_CHECK]:
7035 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7036 (check_string_bytes, make_specified_string, memory_full)
7037 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7038 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7039 (mark_stack, valid_pointer_p, make_pure_string)
7040 (Fgarbage_collect, survives_gc_p, gc_sweep):
7041 Use bool for booleans, instead of int.
7042 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7043 Remove unused local.
7044 * alloc.c (PURE_POINTER_P):
7045 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7046 * editfns.c (Fformat):
7047 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7049 * fns.c (sweep_weak_table):
7050 * lisp.h (suppress_checking, push_message, survives_gc_p)
7051 (make_pure_string, gc_in_progress, abort_on_gc):
7052 * lread.c (readchar, read1):
7053 * print.c (Fprin1_to_string):
7054 * xdisp.c (push_message):
7055 Use bool for booleans affected directly or indirectly by
7058 Make recently-introduced setters macros.
7059 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7060 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7061 (set_fontset_default, set_fontset_fallback): Rename from their
7062 upper-case counterparts, and make them functions rather than macros.
7063 This is more consistent with the other recently-introduced setters.
7064 These don't need to be inline, since they're local.
7066 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7068 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7069 the loop (Bug#12247).
7071 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7073 * lisp.h (vcopy): Use memcpy rather than our own loop.
7074 This fixes a performance regression introduced by the recent
7075 addition of vcopy. This means 'vcopy' will need to be modified
7076 for a copying collector, but that's OK. Also, tighten the
7077 checking in the assertion.
7079 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7081 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7082 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7083 non-base glyph for the width of the base character, according to
7084 what x_draw_composite_glyph_string_foreground expects.
7085 Generate WADJUST value according to composition_gstring_width's
7086 expectations, to produce correct width of the composed character.
7087 Reverse the sign of the DU offset produced by ScriptPlace.
7089 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7091 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7093 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7095 Avoid direct writes to contents member of struct Lisp_Vector.
7096 * lisp.h (vcopy): New function to copy data into vector.
7097 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7098 * fns.c (Ffillarray): Use ASET.
7099 * keyboard.c (timer_check_2): Use AREF and ASET.
7100 (append_tool_bar_item, Frecent_keys): Use vcopy.
7101 * lread.c (read_vector): Use ASET.
7102 * msdos.c (Frecent_doskeys): Use vcopy.
7103 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7104 (Finternal_merge_in_global_face): Use ASET and vcopy.
7105 * xfont.c (xfont_list_pattern): Likewise.
7107 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7109 * window.c (Fwindow_point): For the selected window always return
7110 the position of its buffer's point.
7111 (Fset_window_point): For the selected window always go in its
7112 buffer to the specified position.
7114 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7116 Setter macros for fontsets.
7117 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7118 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7119 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7122 2012-08-20 Glenn Morris <rgm@gnu.org>
7124 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7125 Don't assume that `ln -f' works.
7127 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7129 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7130 and later about non-assignments with no effect. See discussion at
7131 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7134 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7136 Inline setter functions for Lisp_Objects slots of struct specbinding.
7137 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7140 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7142 * window.c (select_window): Always make selected window's buffer
7145 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7147 Use AREF and ASET for docstrings of category tables.
7148 * category.h (CATEGORY_DOCSTRING): Use AREF.
7149 (SET_CATEGORY_DOCSTRING): Use ASET.
7150 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7152 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7154 Inline setter functions for hash table members.
7155 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7156 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7157 (set_hash_key_and_value, set_hash_index, set_hash_next)
7158 (set_hash_hash): New functions.
7159 * charset.c, fns.c: Adjust users.
7161 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7163 Inline getter and setter functions for per-buffer values.
7164 * buffer.h (per_buffer_default, set_per_buffer_default)
7165 (per_buffer_value, set_per_buffer_value): New functions.
7166 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7167 * buffer.c, data.c: Adjust users.
7169 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7171 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7173 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7175 Rely on <config.h> + <unistd.h> to declare 'environ',
7176 as gnulib does this if the system doesn't.
7177 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7178 Remove declaration. MS-Windows declares it on stdlib.h which is
7179 included by conf_post.h.
7180 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7181 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7182 * vm-limit.c: Include <unistd.h>, for 'environ'.
7184 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7185 (start_of_data): Remove decl; mem-limits.h provides it.
7187 * xdisp.c (handle_invisible_prop): Make it a bit faster
7188 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7190 2012-08-19 Chong Yidong <cyd@gnu.org>
7192 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7195 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7197 * .gdbinit: Use call instead of set when calling a function in the
7200 * data.c (set_internal): Don't use set_blv_found.
7201 (Fkill_local_variable): Likewise.
7203 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7205 * nsfont.m (ns_ascii_average_width): Ensure the string
7206 ascii_printable is initialized with a null-terminated character
7207 array. Otherwise, it can contain undesired extra characters.
7209 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7211 port new setting code to Sun C 5.8 2005/10/13
7212 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7213 Return void, not Lisp_Object. Otherwise, the compiler
7214 complains about (A?B:C) where B is void and C is Lisp_Object
7215 when compiling CHAR_TABLE_SET, due to the recent change to
7216 the API of sub_char_table_set_contents.
7218 2012-08-18 Chong Yidong <cyd@gnu.org>
7220 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7221 for the string case (Bug#3874).
7223 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7225 * buffer.h (BSET): Remove (Bug#12215).
7226 Replace all uses with calls to new setter functions.

7254 * category.c (bset_category_table):
7255 * syntax.c (bset_syntax_table):
7256 New setter functions.
7258 * process.h (PSET): Remove (Bug#12215).
7259 Replace all uses with calls to new setter functions.
7260 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7261 (PROCESS_INLINE): New macro.
7262 (pset_childp): New setter function.
7263 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
7264 * process.c (PROCESS_INLINE):
7265 Define to EXTERN_INLINE, so that the corresponding functions
7266 are compiled into code.
7267 (pset_buffer, pset_command, pset_decode_coding_system)
7268 (pset_decoding_buf, pset_encode_coding_system)

8162 since it's used in non-static inline functions now.
8164 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

8218 it easier to think about future improvements. See
8219 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

8601 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8602 (w32_kbd_patch_key, key_event): Use the codepage returned by
8603 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
8604 (key_event): use uChar.UnicodeChar only if
8605 w32_console_unicode_input is non-zero.
8607 * w32console.c: Include w32heap.h.

8632 * alloc.c (listn): Fix the order the arguments are consed onto the
8635 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8636 enumeration constants, as PURE and HEAP are too general, and clash
8637 with other headers and sources, such as gmalloc.c and the
8638 MS-Windows system headers. All users changed.
8640 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8642 Revert last save_excursion_save and save_excursion_restore changes.
8643 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8653 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8655 Improve GDB symbol export (Bug#12036).
8656 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8657 arms of an 'if', not using conditional expressions; otherwise GDB
8658 complains about the types in the unevaluated arm when the argument
8659 is an integer literal.
8660 (xgetint): Simplify expression.
8661 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8662 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8663 Zaretskii in <http://bugs.gnu.org/12036#13>.
8664 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8665 needed now that we have gdb_make_enums_visible.
8666 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8667 (enum enum_USE_LSB_TAG):
8668 New enum types, packaging up enums that need to be exported to GDB.
8670 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8672 Utility function to make a list from specified amount of objects.

8686 * xdisp.c (syms_of_xdisp): Likewise.
8687 * xfns.c (syms_of_xfns): Likewise.
8689 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8691 Fast save_excursion_save and save_excursion_restore.
8692 * lisp.h (struct Lisp_Excursion): New data type.
8693 (PVEC_EXCURSION): New pseudovector type.
8694 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8695 to deal with it. Adjust comments.
8696 (init_marker, attach_marker): New prototype.
8697 (unchain_marker): Adjust prototype.

8706 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8708 Fix export of symbols to GDB (Bug#12036).
8709 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8710 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8711 emacs.c, as this is a more-suitable home. Had this been done earlier
8712 the fix for 12036 would have avoided some of the problems noted in
8713 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8714 would have been more obvious.
8715 * emacs.c: Do not include <verify.h>; no longer needed.
8716 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8717 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8718 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8719 Remove; now done in lisp.h.
8720 * lisp.h (PUBLISH_TO_GDB): New macro.
8721 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8722 (DATA_SEG_BITS): Use it.
8723 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8724 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8725 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8726 not be usable in #if. This simplifies things.
8728 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8730 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8732 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8734 Simplify export of symbols to GDB (Bug#12036).
8735 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8736 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8737 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8738 Adjust to changes in lisp.h and emacs.c, by using
8739 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8740 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8741 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8742 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8743 instead of gdb_valbits.
8744 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8745 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8746 instead of gdb_array_mark_flag.
8747 (xboolvector): Get size from $->size, not $->header.size.
8748 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8749 (xreload, hook-run, hookpost-run): Remove.
8750 * emacs.c: Include <verify.h>.
8751 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8752 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8754 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8755 (gdb_USE_LSB_TAG): New enum constants.
8756 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8757 Also define these as enum constants, so they're visible to GDB.
8758 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8759 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8760 as constants, so they're visible to GDB.
8761 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8762 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8763 Now enum constants, not macros, so they're visible to GDB.
8764 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8765 more convenient now. All uses changed.
8766 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8767 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8769 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8774 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8776 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8777 add argument, tune behavior, and adjust all callers.
8779 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8781 Use typedef for EMACS_INT, EMACS_UINT.
8782 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8783 than macros. This simplifies debugging in the usual case, since
8784 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8785 and it allows expressions involving EMACS_INT casts.
8786 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8788 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8790 * nsterm.m (ns_read_socket): Return early if there is a modal

8796 that FOCUS-FRAME can be omitted.
8798 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8800 Adjust buffer text indirection counters at the end of Fkill_buffer.
8801 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8802 buffer is definitely dead. This should really fix an issue reported
8803 by Christoph Scholtes again. (Bug#12007).
8804 (init_buffer_once): Initialize indirection counters of
8805 buffer_defaults and buffer_local_symbols (for sanity and safety).
8807 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8809 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8810 and continuation glyphs on tooltip frames, leave them at zero.
8811 Avoids continued lines in tooltips. (Bug#11832)
8813 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8815 Simplify copy_overlay.
8816 * buffer.c (copy_overlay): Simplify. Use build_marker.

8825 it signals an error when a tooltip frame is being created.
8827 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8829 Cleanup miscellaneous objects allocation and initialization.
8830 * alloc.c (allocate_misc): Change to static. Add argument to

8836 (build_overlay): Add prototype.
8838 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8840 Swap buffer text indirection counters in Fbuffer_swap_text.
8841 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8842 This avoids crash reported by Christoph Scholtes at
8843 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8845 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8847 * nsmenu.m (Popdown_data): New struct.
8848 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8850 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8851 (initWithContentRect): Make imgView and contentView non-static
8852 and autorelease them. Also autorelease img and matrix (Bug#12005).
8853 (dealloc): Remove (Bug#12005).
8855 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8857 Adjust consing_since_gc when objects are explicitly freed.
8858 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
8859 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
8860 (free_cons, free_misc): Subtract object size from consing_since_gc.
8862 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

8866 (live_buffer, set_marker_internal): New function.
8867 (Fset_marker, set_marker_restricted): Use set_marker_internal.
8868 (set_marker_both, set_marker_restricted_both): Use live_buffer.
8870 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8872 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8873 as it's limited by the amount of memory, not by INT_MAX.
8875 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8877 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8878 in special-event-map. See the discussion at
8879 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
8882 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
8883 info.dwItemData. Fixes crashes on 64-bit Windows.

8937 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8938 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8939 Adjust users accordingly.
8940 * font.h (font_open_by_name): Adjust prototype.
8942 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

8958 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8959 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8960 'for_each_per_buffer_object_at'.
8961 All uses changed. It's better to use upper-case for macros that
8962 cannot be implemented as functions, to give the reader a clue
8963 that they're special.
8965 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8967 * alloc.c (Fgarbage_collect): Tweak docstring.

9007 Fix bug that created negative-length intervals.
9008 * intervals.c (merge_interval_right, merge_interval_left):
9009 Do not zero out this interval if it is absorbed by its children,
9010 as this interval's total length doesn't change in that case. See
9011 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
9013 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9015 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9016 when invoking (make-bool-vector N t) and N is a positive
9017 multiple of 8 -- the last 8 bits were mistakenly cleared.
9019 Remove some struct layout assumptions in bool vectors.
9020 * alloc.c (bool_header_size): New constant.
9021 (header_size, word_size): Move earlier, as they're now used earlier.
9022 Use 'word_size' in a few more places, where it's appropriate.
9023 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
9024 padding before the data member of a bool vector.
9025 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9026 than doing the check by hand with an abort ().
9028 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9030 * eval.c (Fdefvar): Don't check constants since we only set the var if
9031 it's not yet defined anyway (bug#11904).
9033 * lisp.h (last_undo_boundary): Declare new var.
9034 * keyboard.c (command_loop_1): Set it.

9531 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9532 since nothing has defined it on these platforms.

9546 2012-07-11 John Wiegley <johnw@newartisans.com>
9548 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9549 function attribute, so we only use it if it exists in the
9552 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9554 Avoid call to strlen in fast_c_string_match_ignore_case.

9601 * s/aix4-2.h (unix): Remove; no longer needed.
9603 EMACS_TIME simplification (Bug#11875).
9604 This replaces macros (which typically do not work in GDB)
9605 with functions, typedefs and enums, making the code easier to debug.
9606 The functional style also makes code easier to read and maintain.
9607 * systime.h: Include <sys/time.h> on all hosts, not just if
9608 WINDOWSNT, since 'struct timeval' is needed in general.
9609 (EMACS_TIME): Now a typedef, not a macro.
9610 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9612 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9616 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9617 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9618 which are not functions. All uses rewritten to use:
9619 (make_emacs_time): New function.
9620 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9621 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9622 not functions. All uses rewritten to use the following, respectively:
9623 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9624 (add_emacs_time, sub_emacs_time): New functions.
9625 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9626 * fileio.c (Fcopy_file):
9627 * xterm.c (XTflash): Get the current time closer to when it's used.
9628 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9636 * gtkutil.c (get_utf8_string):
9638 * nsmenu.m (ns_update_menubar):
9639 * regex.c (regerror):
9640 Prefer memcpy to strncpy and strncat when either will do.
9641 * fileio.c (Fsubstitute_in_file_name):
9642 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9643 (menu_separator_name_p):
9644 * nsmenu.m (ns_update_menubar):
9645 Prefer memcmp to strncmp when either will do.
9646 * nsterm.m: Include <ftoastr.h>.
9648 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9649 Prefer snprintf to strncpy.
9650 * nsterm.m (ns_term_init):
9651 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9652 * nsterm.m (ns_term_init):
9653 Avoid the need for strncpy, by using build_string or
9654 make_unibyte_string directly. Use dtoastr, not snprintf.
9655 * process.c (Fmake_network_process): Diagnose service names that
9656 are too long, rather than silently truncating them or creating
9657 non-null-terminated names.
9658 (Fnetwork_interface_info): Likewise, for interface names.
9659 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9660 Prefer sprintf to strncat.
9661 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9662 Prefer vsnprintf to vsprintf + strncpy.
9664 2012-07-10 Glenn Morris <rgm@gnu.org>
9666 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9667 Clarify fallback case.
9669 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9671 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9672 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9673 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9674 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9675 where argument type is known to be a Lisp_Cons.
9677 2012-07-10 Tom Tromey <tromey@redhat.com>
9679 * bytecode.c (BYTE_CODE_THREADED): New macro.

9687 Optimize pure C strings initialization.
9688 * lisp.h (make_pure_string): Fix prototype.
9689 (build_pure_c_string): New function, defined as static inline. This
9690 provides a better opportunity to optimize away calls to strlen when
9691 the function is called with compile-time constant argument.
9692 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9693 argument, adjust users accordingly. Use build_pure_c_string where
9695 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9696 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9697 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9699 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9701 Avoid calls to strlen in miscellaneous functions.
9702 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9703 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9704 * lread.c (openp): Likewise.
9706 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9708 Avoid calls to strlen in path processing functions.
9709 * fileio.c (file_name_as_directory): Add comment. Change to add
9710 srclen argument and return the length of result. Adjust users
9712 (directory_file_name): Fix comment. Change to add srclen argument,

9714 Adjust users accordingly.
9715 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9717 2012-07-10 Glenn Morris <rgm@gnu.org>
9719 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9722 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9723 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9724 * s/gnu.h (DATA_START): Move definitions to configure.
9726 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9727 We include usg5-4-common.h, which defines them both.
9729 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9730 O_RDONLY already includes it).
9732 Stop ns builds setting the EMACSLOADPATH environment variable.
9733 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9734 Now it does not set EMACSLOADPATH, just returns the load-path string.
9735 * nsterm.h: Update accordingly.
9736 * lread.c [HAVE_NS]: Include nsterm.h.
9737 (init_lread) [HAVE_NS]: Use ns_load_path.
9738 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9740 2012-07-09 Glenn Morris <rgm@gnu.org>
9742 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9743 since the included bsd-common.h does so.
9745 Stop ns builds setting the EMACSPATH environment variable.
9746 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9747 (ns_init_paths): Do not set EMACSPATH.
9748 * nsterm.h (ns_exec_path): Add it.
9749 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9752 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9754 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9756 * process.c (wait_reading_process_output): 'waitchannels' was unset
9757 when read_kbd || !NILP (wait_for_cell); fix this.
9759 Add GCC-style 'const' attribute to functions that can use it.
9760 * character.h (char_resolve_modifier_mask):
9761 * keyboard.h (make_ctrl_char):
9762 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9763 (init_character_once, next_almost_prime, init_fns, init_image)
9764 (flush_pending_output, init_sound):
9765 * mem-limits.h (start_of_data):
9766 * menu.h (finish_menu_items):
9767 Add ATTRIBUTE_CONST.

9769 Declare the dummy function with ATTRIBUTE_CONST.
9770 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9771 Add decls with ATTRIBUTE_CONST.
9773 Minor improvements to make_formatted_string.
9774 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9775 where int is good enough, as vsprintf returns an int.
9776 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9778 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9780 Use make_formatted_string to avoid double length calculation.
9781 * lisp.h (make_formatted_string): New prototype.
9782 * alloc.c (make_formatted_string): New function.
9783 * buffer.c (Fgenerate_new_buffer_name): Use it.
9784 * dbusbind.c (syms_of_dbusbind): Likewise.
9785 * editfns.c (Fcurrent_time_zone): Likewise.
9786 * filelock.c (get_boot_time): Likewise.
9787 * frame.c (make_terminal_frame, set_term_frame_name)
9788 (x_report_frame_params): Likewise.
9789 * image.c (gs_load): Likewise.
9790 * minibuf.c (get_minibuffer): Likewise.

9805 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9807 Move marker debugging code under MARKER_DEBUG.
9808 * marker.c (MARKER_DEBUG): Move marker debugging code under
9809 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9810 for bootstrap with --enable-checking (~3x slowdown reported
9811 by Juanma Barranquero <lekktu@gmail.com>).
9812 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9814 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9816 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9817 See <http://bugs.gnu.org/11825#29>.
9819 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9821 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9822 has no font, use the frame's font. (Bug#11813)
9823 (display_line): Add commentary about displaying truncation glyphs
9825 (produce_special_glyphs): Move here from term.c.
9827 * term.c (produce_special_glyphs): Move to xdisp.c.
9829 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9832 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9834 * xdisp.c (display_line): Avoid warning about implicit declaration
9837 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9839 * lisp.h: Remove empty conditional.
9841 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9843 * lread.c (load_path_check): Now static.
9845 Fix some minor --with-ns problems found by static checking.
9846 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9847 (x_set_font) [!HAVE_X_WINDOWS]:
9848 * image.c (xpm_load_image) [HAVE_NS]:
9849 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9850 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9851 Remove unused local.
9852 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9853 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9854 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9855 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9856 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9857 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9858 Fix pointer signedness problem.
9859 * xfaces.c (FRAME_X_FONT_TABLE):
9860 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9862 2012-07-07 Glenn Morris <rgm@gnu.org>
9864 * lread.c (load_path_check): New function, split from init_lread.
9865 (init_lread): Reorganize. Motivation:
9866 If EMACSLOADPATH is set, check/warn about that rather than the
9867 defaults, which we are not going to use. Hence we can remove
9868 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9869 Don't warn if site-lisp directories are missing.
9870 If not installed, start from a blank load-path, since
9871 PATH_LOADSEARCH refers to the eventual installation directories.
9873 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9875 Support truncation and continuation glyphs on GUI frames, when
9876 fringes are disabled. (Bug#11832)
9877 * xdisp.c (init_iterator): Get dimensions of truncation and
9878 continuation glyphs even if on GUI frames.
9879 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9880 or both, are absent.
9881 (start_display, move_it_in_display_line_to): Handle the case of a
9882 GUI frame without a fringe to display continuation or truncation
9884 (insert_left_trunc_glyphs): Support GUI frames: make sure
9885 truncation glyphs overwrite enough glyphs from the current line to
9886 have sufficient space in pixels.
9887 (display_line): Support truncation and continuation glyphs on GUI
9888 frames. If some spare pixels are left on the line after inserting
9889 the truncation glyphs, fill that space with a stretch glyph of a
9890 suitably computed width.
9892 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9893 produce_glyphs, to support GUI sessions.
9895 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9897 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9899 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9901 Do not require float-time's arg to fit in time_t (Bug#11825).
9902 This works better on hosts where time_t is unsigned, and where
9903 float-time is applied to the (negative) difference between two times.
9904 * editfns.c (decode_time_components): Last arg is now double *,
9905 not int *, and means to store all the result as a double, without
9906 worrying about whether the seconds part fits in time_t.
9907 All callers changed.
9908 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9909 All callers changed.
9910 (Ffloat_time): Do not fail merely because the specified time falls
9911 outside of time_t range.
9913 2012-07-07 Glenn Morris <rgm@gnu.org>
9915 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9919 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9921 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9922 Update dependencies.
9924 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9926 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9928 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9929 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9930 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.

9940 * w32fns.c (Fx_change_window_property): Doc fix.
9942 * w32fns.c (Fx_window_property): Accept the same arguments as the
9943 X Windows version. Doc fix.
9944 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9946 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9947 Eli Zaretskii <eliz@gnu.org>
9949 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

9951 Obsolete settings removed.
9953 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9955 * process.c: Avoid unnecessary calls to gettime.
9956 (wait_reading_process_output): Don't get the time of day
9957 when gobbling data immediately and not waiting, as there's no need
9958 for it in that case. This removes a FIXME.
9960 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9962 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9963 is defined (Bug#11768).

9971 Call byte_char_debug_check with correct arguments.
9973 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9975 Compile marker debugging code only if ENABLE_CHECKING is defined.
9976 * marker.c (byte_char_debug_check, count_markers):
9977 Use only if ENABLE_CHECKING is defined.
9978 (byte_debug_flag): Remove.
9979 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9980 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

10015 to avoid redundant calls to unchain_overlay.
10016 * buffer.c (drop_overlay): New function.
10017 (delete_all_overlays, Fdelete_overlay): Use it.
10018 * minibuf.c (get_minibuffer): Fix comment.
10020 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10022 Port to OpenBSD 5.1 amd64.
10023 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10024 This is needed for OpenBSD, and should be harmless on all BSD systems.
10025 Also, include <sys/sysctl.h>, as it should be available on all
10026 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10027 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10028 use p_pid member, not kp_proc.pid.
10030 2012-07-06 Glenn Morris <rgm@gnu.org>
10032 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10034 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10036 More xmalloc and related cleanup.

10047 Omit needless casts involving void * pointers and allocation.
10048 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10049 as the former is more robust if P's type is changed.
10050 Prefer xzalloc to xmalloc + memset 0.
10051 Simplify malloc-or-realloc to realloc.
10052 Don't worry about xmalloc returning a null pointer.
10053 Prefer xstrdup to xmalloc + strcpy.
10054 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10056 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10057 alloca of a constant.

10061 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10062 hscroll is larger than the line width. Fixes long and futile
10063 looping inside extend_face_to_end_of_line (on a TTY) producing
10064 glyphs that are not needed and thrown away.
10066 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10068 * marker.c (set_marker_restricted_both): Simplify by using
10071 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10073 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10082 followed by gtk_box_set_homogeneous (Bug#11768).
10083 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10084 (update_theme_scrollbar_width, xg_create_scroll_bar):
10085 Use gtk_scrollbar_new (Bug#11768).

10087 (is_box_type): New function (Bug#11768).
10088 (xg_tool_item_stale_p): Call is_box_type.
10089 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10090 with default display (Bug#11768).
10092 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10094 * xdisp.c (window_hscroll_limited): New function.
10095 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10096 coordinates when window's hscroll is set to insanely large
10097 values. (Bug#11857)
10099 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10162 * fileio.c (time_error_value): Check the right error number.
10163 Problem reported by Troels Nielsen in
10164 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10166 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10168 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10169 This should be fixed in a better way; see Eli Zaretskii in
10170 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10171 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10173 * fileio.c (time_error_value): Rename from special_mtime.
10174 The old name's problems were noted by Eli Zaretskii in
10175 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10177 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10178 This variable's comment says Emacs needs at least one GDB-visible
10179 symbol of type enum pvec_type, to work around GDB problems.
10180 The symbol's value doesn't matter.
10182 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10183 that causes compilation to fail on pre-C99 compilers.
10185 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10187 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10211 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10212 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10213 abusing vector->header.next.nbytes.
10214 (live_vector_p): Use PVEC_TYPE.
10215 (mark_object): Adapt code to extract pvectype. Use switch.
10217 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10219 * doprnt.c (doprnt): Don't assume string length fits in 'int'.

10224 Fix compilation with --enable-gcc-warnings and -O1
10225 optimization level.
10226 * doprnt.c (doprnt): Change type of tem to int, initialize
10227 to avoid compiler warning. Add eassert.
10228 * search.c (simple_search): Initialize match_byte to avoid
10229 compiler warning. Add eassert.
10231 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10233 Avoid weird behavior with large horizontal scrolls.
10234 Without this change, for example, large hscroll values would
10235 mess up Emacs's display on Fedora 15 x86, presumably due to
10236 overflows in int calculations in the display code.
10237 Also, if buffers had long lines, Emacs would freeze.
10238 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10239 (set_window_hscroll): New function, containing the old guts of
10240 Fset_window_hscroll. Return the clipped value.
10241 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10242 This avoids the need to check against PTRDIFF_MAX.
10244 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10246 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10248 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10250 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10252 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10253 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10254 since GCC 4.4.6 issues a bogus warning for them.
10256 Fix bugs in file timestamp newness comparisons.
10257 * fileio.c (Ffile_newer_than_file_p):
10258 * lread.c (Fload): Use full timestamp resolution of files,
10259 not just the 1-second resolution, so that files that are only
10260 slightly newer still count as newer.
10261 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10262 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10264 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10266 * fileio.c: Improve handling of file time marker. (Bug#11852)

10276 2012-07-03 Glenn Morris <rgm@gnu.org>
10278 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10279 and did not make it into globals.h).
10281 2012-07-03 Tom Tromey <tromey@redhat.com>

10341 * alloc.c (allocate_vector_block): Remove redundant
10342 calls to mallopt if DOUG_LEA_MALLOC is defined.
10343 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10344 avoid calls to mallopt if zero_vector is returned.
10346 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10348 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10349 is enabled, avoid dereferencing NULL current_sblock if
10352 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10354 Cleanup basic buffer management.
10355 * buffer.h (struct buffer): Change layout to use generic vector

10370 and related comments.
10372 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10374 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10375 wrapper that is not needed because the wrapped code is a no-op (zero
10376 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10377 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10379 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10381 * alloc.c (mark_buffer): Simplify. Remove prototype.
10382 (mark_object): Add comment. Reorganize marking of vector-like
10383 objects. Use CHECK_LIVE for all vector-like objects except buffers
10384 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10385 Avoid redundant calls to mark_vectorlike for bool vectors.
10387 2012-06-30 Glenn Morris <rgm@gnu.org>
10389 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10391 * epaths.in (PATH_SITELOADSEARCH): New.
10392 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10393 This is rather than relying on --enable-locallisppath elements
10394 having "site-lisp" in their names. (Bug#10208#25, 11658)
10396 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10398 * w32proc.c (sys_select): Accept and ignore one more argument.
10400 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10402 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10403 (pselect) [!MS_DOS]: Redirect to sys_select.
10405 * sysdep.c: Don't include dos.h and dosfns.h.
10407 * process.c (sys_select):
10408 * msdos.c (sys_select): Accept one more argument and ignore it.
10410 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10411 adapt data types and code to that.
10414 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10415 which clashes with the gnulib function of the same name.
10417 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10419 * font.c (font_style_to_value, font_style_symbolic)
10420 (font_prop_validate_style): Add type checks for values in
10423 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10425 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10428 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10430 * xdisp.c (try_window_id): Undo last change.
10432 * w32.c (getwd): Adjust commentary about startup_dir.
10433 (init_environment): Always call sys_access, even in non-MSVC
10434 builds. Don't chdir to the directory of the Emacs executable.
10435 This undoes code from 1997 which was justified by the need to
10436 "avoid conflicts when removing and renaming directories". But its
10437 downside was that every relative file name was being interpreted
10438 relative to the directory of the Emacs executable, which can never
10439 be TRT. In particular, it broke sys_access when called with
10440 relative file names.
10441 (sys_access): Map GetLastError to errno.
10443 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10445 * window.h (struct window): Change type of 'fringes_outside_margins'
10446 to bitfield. Fix comment. Adjust users accordingly.
10447 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10449 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10452 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10454 * gnutls.c (emacs_gnutls_handshake):
10455 Add QUIT to make the loop interruptible.
10457 2012-06-29 Glenn Morris <rgm@gnu.org>
10459 * charset.c (init_charset): Make lack of etc/charsets fatal.
10461 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10463 * editfns.c (region_limit): Fix type mismatch.
10465 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10467 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10468 undefined. Convert from xassert to eassert.
10469 * nsmenu.m: Convert from xassert to eassert.
10470 * nsterm.m: Likewise.
10472 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10476 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10478 Avoid integer overflow on scroll-left and scroll-right.
10479 * window.c (HSCROLL_MAX): New macro.
10480 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10481 overflow when requested scroll falls outside ptrdiff_t range.
10483 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10485 * window.h (struct window): Change type of 'hscroll',
10486 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10487 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10488 Adjust users accordingly.
10489 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10490 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10491 from EMACS_INT to ptrdiff_t.
10492 (make_window): Omit redundant initialization.
10494 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

10498 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10500 * window.h (struct window): Change type of 'use_time' and
10501 'sequence_number' from Lisp_Object to int.

10510 enabled with --enable-checking=[all,glyphs] configure option.
10511 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10512 adjust comments accordingly.

10514 undefined, adjust comments accordingly.

10559 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10561 * alloc.c (allocate_string_data): Remove dead code.
10562 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
10563 avoid GCC warning about unused macro.
10565 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10567 * alloc.c (allocate_string): Omit intervals initialization.
10568 * alloc.c (make_uninit_multibyte_string): Initialize intervals

10591 on Mac OS X Lion: __mod_init_func and __mod_term_func.
10593 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10594 when building with Clang.
10596 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

10623 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
10625 * alloc.c: Remove build_string.
10626 * lisp.h: Define build_string as static inline. This provides
10627 a better opportunity to optimize away calls to strlen when the
10628 function is called with compile-time constant argument.
10629 * image.c (imagemagick_error): Convert to build_string.
10630 * w32proc.c (sys_spawnve): Likewise.
10631 * xterm.c (x_term_init): Likewise.
10633 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10635 Use sprintf return value instead of invoking strlen on result.
10636 In the old days this wasn't portable, since some sprintf
10637 implementations returned char *. But they died out years ago and
10638 Emacs already assumes sprintf returns int.
10639 Similarly for float_to_string.
10640 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10641 * ccl.c (ccl_driver):

10645 * print.c (print_object):
10646 * xdisp.c (message_dolog):
10647 * xfns.c (syms_of_xfns):
10648 Use sprintf or float_to_string result to avoid need to call strlen.
10649 * data.c (Fnumber_to_string):
10650 Use make_unibyte_string, since the string must be ASCII.
10651 * lisp.h, print.c (float_to_string): Now returns int length.
10652 * term.c (produce_glyphless_glyph):
10653 Use sprintf result rather than recomputing it.
10655 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10656 * Makefile.in (ALL_CFLAGS):
10657 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10658 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10660 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10662 * dispextern.h (xstrcasecmp): Define to library function
10663 strcasecmp if available.
10664 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10666 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10668 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10681 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10682 sprintf already null-terminates its output.
10684 * xfns.c (x_window): Remove redundant cast.
10686 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10688 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10689 `const char *' to `char *' to avoid compiler warning.
10691 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10693 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10694 instead of truncating it to 63 (admittedly a generous limit).
10696 * process.c: Fix spelling and caps in comments.
10698 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10700 * emacs.c (setpgrp): Remove definition, unused.

10710 (SYSTIME_H): Add nt/inc/sys/time.h.
10712 * systime.h [WINDOWSNT]: Include sys/time.h.
10714 * s/ms-w32.h (struct timespec): Definition moved from
10715 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

10745 No need for separate decl merely because of _Noreturn.
10746 * sound.c (sound_warning, parse_sound):
10747 Remove unnecessary forward decls.
10749 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10751 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10752 * lisp.h (WAIT_READING_MAX): New macro.
10753 * dispnew.c (Fsleep_for, sit_for):
10754 * keyboard.c (kbd_buffer_get_event):
10755 * process.c (Faccept_process_output):
10756 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10757 This improves on the previous patch, which introduced a bug
10758 when time_t is unsigned and as wide as intmax_t.
10759 See <http://bugs.gnu.org/9000#51>.
10761 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10763 * dispnew.c (sit_for, Fsleep_for):
10764 * keyboard.c (kbd_buffer_get_event):

10777 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10778 Privately reported by Herbert J. Skuhra.
10779 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10781 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10782 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10784 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10786 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10787 last argument of make_unibyte_string.
10789 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10790 language ID in the event parameters.
10792 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10793 event.code, not the obscure "character set ID".
10795 2012-06-23 Chong Yidong <cyd@gnu.org>
10797 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10806 * s/ms-w32.h (pselect): Redirect to sys_select.
10808 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
10810 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
10811 in the logic of incrementing and decrementing the value of
10812 use_relocatable_buffers.
10814 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
10816 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.

10826 Support higher-resolution time stamps (Bug#9000).
10827 The time stamps are only nanosecond-resolution at the C level,
10828 since that's the best that any real-world system supports now.
10829 But they are picosecond-resolution at the Lisp level, as that's
10830 easy, and leaves room for future OS improvements.
10832 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10835 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10836 Don't get current time unless it's needed.
10838 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10839 now provides it if it's absent.
10840 (start_atimer): Port to higher-res time stamps.
10841 Check for time stamp overflow. Don't get current time more
10842 often than is needed.
10844 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10845 Include systime.h, not time.h.
10846 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10848 * dired.c: Include stat-time.h.
10849 (Ffile-attributes): File times now have higher resolution.
10851 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10852 (struct image): Timestamp now has higher resolution.
10854 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10855 has at least microseconds now. All uses removed.
10856 (update_frame, update_single_window, update_window, update_frame_1)
10857 (Fsleep_for, sit_for): Port to higher-resolution time stamps.

10868 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10869 Report an error if the time is invalid, rather than having the caller
10872 * fileio.c: Include <stat-time.h>
10873 (Fcopy_file): Copy higher-resolution time stamps.
10874 Prefer to set the time stamp via a file descriptor if that works.

10892 Port to higher-resolution time stamps. Do not assume time_t is signed.
10893 (decode_timer): New function. Timers are now vectors of length 9,
10894 not 8, to accommodate the picosecond component.
10895 (timer_check_2): Use it.
10897 * nsterm.m (select_timeout, timeval_subtract): Remove.
10898 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10899 as they're a bit more accurate and handle overflow better.
10900 (ns_select): Change prototype to be compatible with pselect.
10901 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10902 * nsterm.h (ns_select): Adjust prototype.

10919 (wait_reading_process_output):
10920 Port to ns-resolution time stamps.
10921 (Faccept_process_output, wait_reading_process_output):
10922 Check for time stamp overflow. Do not assume time_t is signed.
10923 (select_wrapper): Remove; we now use pselect.
10924 (Fprocess_attributes): Now generates ns-resolution time stamps.
10926 * sysdep.c: Include utimens.h. Don't include utime.h
10927 or worry about struct utimbuf; gnulib does that for us now.
10928 (gettimeofday): Remove; gnulib provides a substitute.
10929 (make_timeval): New function.
10930 (set_file_times): Now sets ns-resolution time stamps.
10931 New arg FD; all uses changed.

10934 Now returns ns-resolution time stamp. All uses changed.
10935 Check for time stamp overflow.

10938 provides a substitute now.
10940 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10941 since it guarantees struct timespec.
10942 (EMACS_TIME): Now struct timespec, so that we can support
10943 ns-resolution time stamps.
10944 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10945 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10946 (EMACS_USECS): Remove.
10947 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10948 so multiply the arg by 1000 before storing it.

10958 (make_timeval, make_lisp_time, decode_time_components): New decls.
10959 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10960 that it mishandled time_t overflow. You can't compare by subtracting!
10961 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10962 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10964 * term.c: Include <sys/time.h>.

10969 in the undo buffer.
10970 (Fprimitive_undo): Use them when restoring time stamps.

10973 (w32_get_internal_run_time):
10974 Port to higher-resolution Emacs time stamps.

10978 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10980 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10981 for compatibility with pselect. Support ns-resolution time stamps.
10983 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10985 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10986 Check for time stamp overflow, and support ns-resolution time stamps.

10989 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10990 (timeval_subtract): Remove; no longer needed.
10991 (XTflash, XTring_bell, x_wait_for_event):
10992 Port to ns-resolution time stamps. Don't assume time_t is signed.

10998 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11000 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11001 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11002 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11003 staticidx goes up to 1597 out of 1600 = 0x640.)
11005 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11007 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11019 access to `contents' member of Lisp_Vector objects with AREF and ASET
11022 2012-06-19 Chong Yidong <cyd@gnu.org>
11024 * frame.c (delete_frame): When selecting a frame on a different
11025 text terminal, do not alter the terminal's top-frame.

11029 (unwind_format_mode_line): Restore them.
11030 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11032 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11033 since tty frames can be explicitly named.
11034 (prepare_menu_bars): Likewise.
11036 * term.c (Ftty_top_frame): New function.
11038 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11041 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11042 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11043 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11044 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11045 (METER_1, METER_2): Simplify.
11047 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11049 * data.c (Fdefalias): Return `symbol' (bug#11686).
11051 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11053 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11054 gets killed during executing of this function (Bug#11665).
11055 Try to always return Qt when the buffer has been actually killed.
11056 (Vkill_buffer_query_functions): In doc-string say that functions
11057 run by this hook should not change the current buffer.
11059 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11061 Fix recently-introduced process.c problems found by static checking.

11081 * lisp.h (eassert): Assume C89 or later.
11082 This removes the need for CHECK.
11083 (CHECK): Remove. Its comments about always evaluating its
11084 argument were confusing, as 'eassert' typically does not evaluate
11087 * coding.c (produce_chars): Use ptrdiff_t, not int.
11089 * xterm.c (x_draw_underwave): Check for integer overflow.
11090 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11277 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11278 Use an inline function on all platforms when using the union type,
11279 since this is simpler and 'static inline' can be used portably

11421 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11423 * doprnt.c (doprnt): Truncate multibyte char correctly.
11424 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11425 would mishandle a string argument "Xc" if X was a multibyte
11426 character of length 2: it would truncate after X's first byte
11427 rather than including all of X.
11429 2012-06-06 Chong Yidong <cyd@gnu.org>
11431 * buffer.c (word_wrap): Doc fix.

11478 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11480 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11481 Convert pctcpu and pctmem to Lisp float properly.
11482 Let the compiler fold better, as 100.0/0x8000 is exact.
11484 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11486 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11493 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11495 For a 'struct window', replace some Lisp_Object fields to
11496 bitfields where appropriate, remove unused fields.
11497 * window.h (struct window): Remove unused 'last_mark_x' and
11498 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11499 change its type from Lisp_Object to bitfield.
11500 Change type of 'force_start', 'optional_new_start',
11501 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11502 fields from Lisp_Object to bitfield. Adjust users accordingly.
11504 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11506 Pacify gcc -Wdouble-precision when using Xaw.
11507 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11508 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11509 Use 'float' consistently, rather than 'float' in most places
11510 and 'double' in a couple of places.
11512 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11514 * xdisp.c (handle_stop): Detect whether we have overlay strings
11515 loaded by testing it->current.overlay_string_index to be
11516 non-negative, instead of checking whether n_overlay_strings is
11517 positive. (Bug#11587)
11519 2012-05-31 Chong Yidong <cyd@gnu.org>
11521 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11527 * search.c (search_buffer): Remove calls to
11528 r_alloc_inhibit_buffer_relocation, as it is now called by
11529 maybe_unify_char, which was the cause of relocation of buffer text
11532 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11534 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11535 for the duration of call to load_charset, to avoid problems with
11536 callers of maybe_unify_char that access buffer text through C
11539 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11540 decrement the inhibition flag, instead of just setting or
11543 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11545 Remove obsolete '#define static' cruft.
11546 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11547 This #undef was "temporary" in 2000; it is no longer needed
11548 now that '#define static' has gone away.
11549 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11550 (gray_bitmap_bits): Remove; no longer needed.
11551 All uses replaced with definiens.

11557 The following changes affect the code only when profiling.
11558 * dispnew.c (__executable_start): Rename from safe_bcopy.
11559 Define only on platforms that need it.
11560 * emacs.c: Include <sys/gmon.h> when profiling.
11561 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11562 (__executable_start): Remove decl, since lisp.h does it now.
11563 (safe_bcopy): Remove decl; no longer has that name.
11564 (main): Coalesce #if into single bit of code, for simplicity.
11565 Cast pointers to uintptr_t, since standard libraries want integers
11567 * lisp.h (__executable_start): New decl.
11569 2012-05-31 Glenn Morris <rgm@gnu.org>
11571 * image.c (Fimagemagick_types): Doc fix.

11594 Do not create empty overlays with the evaporate property (Bug#9642).
11595 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11596 Bug#9642, but explicitly check that the buffer the overlay would
11597 be moved to is live and rearrange lines to make sure that errors
11598 will not put the overlay in an inconsistent state.
11599 (Fdelete_overlay): Cosmetics.
11601 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11603 * w32term.c (my_bring_window_to_top): New function.
11604 (x_raise_frame): Use handle returned by DeferWindowPos, which
11605 could be different from the original one.

11618 This avoids undefined behavior that might cause the eassert
11619 to not catch an out-of-range value.
11621 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11623 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11637 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11638 Only r_alloc_inhibit_buffer_relocation needed to be added;
11639 the others were already declared.
11641 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11642 before checking whether it's out of range. Put the check inside
11644 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11646 2012-05-27 Ken Brown <kbrown@cornell.edu>

11658 they are now on lisp.h.
11660 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11662 * search.c (search_buffer): Use it to inhibit relocation of buffer
11663 text while re_search_2 is doing its job, because re_search_2 is
11664 passed C pointers to buffer text. (Bug#11519)
11666 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11667 Update value to 24.
11669 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11670 state after an additional call to move_it_in_display_line_to, keep
11671 the values of it->max_ascent and it->max_descent found for the
11673 (pos_visible_p): Revert the comparison against bottom_y to what it
11674 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11677 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11679 Fix coding-related core dumps with gcc -ftrapv.
11680 The code was computing A - B, where A and B are pointers, and B is
11681 random garbage. This can lead to core dumps on platforms that
11682 have special pointer registers, and it also leads to core dumps on
11683 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11684 A - B only when B is initialized properly.
11685 * coding.c (coding_set_source, coding_set_destination): Return void.
11686 (coding_change_source, coding_change_destinations): New functions,
11687 with the old behaviors of coding_set_source and coding_set_destination.

11698 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11700 * w32console.c: Include window.h.
11701 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11703 (initialize_w32_display): Initialize mouse-highlight data.
11705 * w32inevt.c: Include termchar.h and window.h.
11706 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11707 moves, call note_mouse_highlight. If help_echo changed, call
11708 gen_help_event to produce help-echo message in the echo area.
11709 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11712 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11714 * lread.c (read1): Simplify slightly to avoid an overflow warning
11715 with GCC 4.7.0 on x86-64.
11717 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11719 * bidi.c (bidi_mirror_char): Revert last change: an int is
11720 definitely wide enough here.

11730 (make_string_from_bytes, make_specified_string)
11731 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11732 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11734 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11735 (allocate_pseudovector):
11736 Use int, not EMACS_INT, where int is wide enough.
11737 (inhibit_garbage_collection, Fgarbage_collect):
11738 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11739 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11740 int might not be wide enough.
11741 (bidi_cache_search, bidi_cache_find, bidi_init_it)

11758 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11759 (validate_region): Omit unnecessary test for b <= e,
11760 since that's guaranteed by the previous test.
11761 (adjust_overlays_for_delete): Avoid pos + length overflow.
11762 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11763 (report_overlay_modification):
11764 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11765 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11766 Omit pointer cast, which isn't needed anyway, and doesn't work
11767 after the EMACS_INT -> ptrdiff_t change.
11768 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11769 * buffer.h: Adjust decls to match defn changes elsewhere.

11772 Use EMACS_INT, not int, where int might not be wide enough.
11773 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11774 not int, to avoid needless 32-bit limit on 64-bit hosts.
11775 (exec_byte_code): Use tighter memory-full test, one that checks
11776 for alloca overflow. Don't compute the address of the object just
11777 before an array, as that's not portable. Use EMACS_INT, not
11778 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11779 * callint.c (Fcall_interactively):
11780 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11781 * callproc.c (call_process_kill, Fcall_process):
11782 Don't assume pid_t fits into an Emacs fixnum.

11793 (casify_object): Avoid integer overflow when overallocating buffer.
11794 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11795 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11796 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11797 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11798 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

11802 For CCL_MapSingle, check that content and value are in int range.
11803 (ccl_driver, Fregister_code_conversion_map):
11804 Check that Vcode_version_map_vector is a vector.
11805 (resolve_symbol_ccl_program): Check that vector header is in range.
11806 Always copy the vector, so that we can check its contents reliably
11807 now rather than having to recheck each instruction as it's being
11808 executed. Check that vector words fit in 'int'.
11809 (ccl_get_compiled_code, Fregister_ccl_program)
11810 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11811 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

11813 contents are in range.
11814 (Fccl_execute_on_string): Check that status is in range.
11815 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11816 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11817 Accept and return EMACS_INT, not int, because callers can pass values

11835 Remove now-unnecessary CHECK_NATNUMs.
11836 (Fdefine_charset_internal): Check ranges here, more carefully.
11837 Don't rely on undefined behavior with signed left shift overflow.
11838 Don't assume unsigned int fits into fixnum, or that fixnum fits
11839 into unsigned int. Don't require max_code to be a valid fixnum;
11840 that's not true for gb10830 4-byte on a 32-bit host. Allow
11841 invalid_code to be a cons, for the same reason. Require code_offset
11842 to be a character. Avoid int overflow if max_char is close
11844 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11845 this is intended anyway and avoids some undefined behavior.
11846 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11847 INDEX_TO_CODE_POINT, as that's what it expects.
11848 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11849 * charset.h (DECODE_CHAR): Return int, not unsigned;
11850 this is what was intended anyway, and it avoids undefined behavior.
11851 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11852 integer-overflow issues.
11853 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11854 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11855 where the argument is EMACS_INT, and this behavior is not intended.
11856 * chartab.c (Fmake_char_table, Fset_char_table_range)
11857 (uniprop_get_decoder, uniprop_get_encoder):
11858 Don't assume fixnum fits in int.
11859 * cmds.c (move_point): New function, that does the gist of
11860 Fforward_char and Fbackward_char, but does so while checking
11861 for integer overflow more accurately.
11862 (Fforward_char, Fbackward_char): Use it.
11863 (Fforward_line, Fend_of_line, internal_self_insert)
11864 (internal_self_insert):
11865 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12512 * xterm.c (x_x_to_emacs_modifiers):
12513 Don't assume EMACS_INT overflows nicely into int.
12514 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12515 may come from Lisp.

12524 2012-05-25 Glenn Morris <rgm@gnu.org>
12526 * lisp.mk (lisp): Update for more files being compiled now.
12528 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12530 * lread.c: Remove `read_pure' which makes no difference.
12531 (read_pure): Remove var.
12532 (unreadpure): Remove function.
12533 (readevalloop): Don't call read_list with -1 flag.
12534 (read1, read_vector): Don't test read_pure any more.

12546 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12548 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12551 This directory predates autoconf and is no longer needed nowadays.
12552 Move its few remaining bits of functionality to where they're needed.
12553 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12554 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

12556 * Makefile.in (M_FILE): Remove. All uses removed.

12558 * lisp.h (USE_LSB_TAG):
12559 * mem-limits.h (EXCEEDS_LISP_PTR):
12560 Use VAL_MAX, not VALBITS, in #if.
12561 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12562 (EMACS_UINT): Define unconditionally now.
12563 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12564 (BITS_PER_EMACS_INT): New constants, replacing
12565 what used to be in config.h, but not useful in #if.
12566 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12567 define them any more.
12568 (VAL_MAX): New macro.
12570 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12571 BITS_PER_EMACS_INT, in #if.
12572 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12573 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12574 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:

12576 Move here from removed file m/intel386.h.
12577 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12578 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12580 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12582 Assume C89 or later.
12583 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

12605 2012-05-19 Ken Brown <kbrown@cornell.edu>
12607 * xfns.c (x_in_use): Remove `static' qualifier.
12608 * xterm.h (x_in_use): Declare.
12609 * xgselect.c: Include xterm.h.
12610 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12611 and `display_arg' (bug#9754).
12613 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12615 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

12625 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12627 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12628 reference to image_cache->refcount.
12629 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12631 2012-05-17 Juri Linkov <juri@jurta.org>
12633 * search.c (Fword_search_regexp, Fword_search_backward)
12634 (Fword_search_forward, Fword_search_backward_lax)
12635 (Fword_search_forward_lax): Move functions to isearch.el
12636 (bug#10145, bug#11381).
12638 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12640 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12642 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12644 * lread.c (init_obarray): Declare Qt and Qnil as special.
12646 2012-05-14 Glenn Morris <rgm@gnu.org>
12648 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12649 Put "libexec" before "bin", for the sake of init_callproc_1.
12651 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12653 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12655 * unexaix.c: Port to more-recent AIX compilers.
12656 (report_error, report_error_1, make_hdr, copy_sym)
12657 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12658 Make arguments const char *, not char *, to avoid violations of C
12659 standard and to fix some AIX warnings reported by Gilles Pion.
12661 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12663 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12664 already have overlays loaded.
12665 (handle_single_display_spec): Before returning without displaying
12666 fringe bitmap, synchronize the bidi iterator with the main display
12667 iterator, by calling iterate_out_of_display_property.
12668 (iterate_out_of_display_property): Detect buffer iteration by
12669 testing that it->string is a Lisp string.
12670 (get_next_display_element): When the current object is exhausted,
12671 and there's something on it->stack, call set_iterator_to_next to
12672 proceed with what's on the stack, instead of returning zero.
12673 (set_iterator_to_next): If called at the end of a Lisp string,
12674 proceed to consider_string_end without incrementing string
12675 position. Don't increment display vector index past the end of
12676 the display vector. (Bug#11417)
12677 (pos_visible_p): Don't report a position visible when move_it_to
12678 stopped at the last line of window, which happens to be scanned
12679 backwards by the bidi iteration. (Bug#11464)
12681 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12683 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12684 and right-margin display specs even if the spec is invalid or we
12685 are on a TTY, and thus unable to display on the fringes.
12686 That's because the text with the property will not be displayed anyway,
12687 so we need to signal to the caller that this is a "replacing"
12688 display spec. This fixes display when the spec is invalid or we
12691 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12693 * unexaix.c (make_hdr): Fix typo in prototype.
12694 This bug broke the build on AIX. Problem reported by Gilles Pion.
12696 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12698 * keyboard.c (kbd_buffer_get_event): Read special events also in
12699 batch mode. (Bug#11415)
12701 2012-05-12 Glenn Morris <rgm@gnu.org>
12703 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12705 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12707 * lisp.mk (lisp): Add newcomment.elc.
12709 2012-05-12 Glenn Morris <rgm@gnu.org>
12711 * Makefile.in (MKDIR_P): New, set by configure.
12712 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12714 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12716 Remove unused function hourglass_started.
12717 * dispextern.h (hourglass_started):
12718 * w32fns.c (hourglass_started):
12719 * xdisp.c (hourglass_started): Remove.
12721 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12723 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12724 Update dependencies.
12726 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12728 * xgselect.c (xg_select): Put maxfds+1 into a var.
12729 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12731 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12733 2012-05-10 Dave Abrahams <dave@boostpro.com>
12735 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12736 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12738 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12740 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12741 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12742 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12743 Initialize xd_registered_buses.
12745 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12747 Untag more efficiently if USE_LSB_TAG.
12748 This is based on a proposal by YAMAMOTO Mitsuharu in
12749 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12750 For an admittedly artificial (nth 8000 longlist) benchmark on
12751 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12752 Emacs's overall text size by 1%.
12753 * lisp.h (XUNTAG): New macro.
12754 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12755 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12756 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12757 * eval.c (Fautoload):
12758 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12759 * frame.h (XFRAME): Use XUNTAG.
12761 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12762 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12763 Remove unportable assumptions about print widths of types like
12765 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12766 intptr_t when converting between pointer and integer, to avoid GCC
12767 warnings about wrong width.
12769 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12771 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12772 stack for each reader_thread, instead of defaulting to 8MB
12773 determined by the linker. This avoids failures in creating
12774 subprocesses on Windows 7, see the discussion in this thread:
12775 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12777 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12779 Fix up display of the *Minibuf-0* buffer in the mini window.
12780 * keyboard.c (read_char): Don't clear the echo area if there's no
12782 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12783 contents of *Minibuf-0*) if there's no message displayed in its stead.
12785 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12787 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12790 2012-05-06 Chong Yidong <cyd@gnu.org>
12792 * lisp.mk (lisp): Update.
12794 2012-05-05 Jim Meyering <meyering@redhat.com>
12796 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12798 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12800 * data.c (PUT_ERROR): New macro.
12801 (syms_of_data): Use it. Add new error type `user-error'.
12802 * undo.c (user_error): New function.
12803 (Fprimitive_undo): Use it.
12804 * print.c (print_error_message): Adjust print style for `user-error'.
12805 * keyboard.c (user_error): New function.
12806 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12808 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12810 Do not limit current-time-string to years 1000..9999.
12811 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12812 (Fcurrent_time_string): Support any year that is supported by the
12813 underlying localtime representation. Don't use asctime, as it
12814 has undefined behavior for years outside the range -999..9999.
12816 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12818 Fix race conditions involving setenv, gmtime, localtime, asctime.
12819 Without this fix, interrupts could mess up code that uses these
12820 nonreentrant functions, since setting TZ invalidates existing
12821 tm_zone or tzname values, and since most of these functions return
12822 pointers to static storage.
12823 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12824 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12825 Grow the critical sections to include not just invoking
12826 localtime/gmtime, but also accessing these functions' results
12827 including their tm_zone values if any, and any related TZ setting.
12828 (format_time_string): Last arg is now struct tm *, not struct tm **,
12829 so that the struct tm is saved in the critical section.
12830 All callers changed. Simplify allocation of initial buffer, partly
12831 motivated by the fact that memory allocation needs to be outside
12832 the critical section.
12834 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12836 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12837 with RESET_INTERVAL.
12839 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12840 Remove duplicated buffer name initialization.
12842 2012-05-02 Jim Meyering <jim@meyering.net>
12844 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12846 * xfns.c (x_window): Use xstrdup (Bug#11375).
12848 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12850 * xdisp.c (pos_visible_p): If already at a newline from the
12851 display string before the 'while' loop, don't walk back the glyphs
12852 from it3.glyph_row. Solves assertion violation when the display
12853 string begins with a newline (egg.el). (Bug#11367)
12855 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12857 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12860 2012-05-01 Glenn Morris <rgm@gnu.org>
12862 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12863 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12864 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12865 All were removed before 23.1.
12867 * dispnew.c: Remove HAVE_LIBNCURSES test;
12868 it is always true on relevant platforms.
12870 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12871 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12873 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12875 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12877 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12878 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12881 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12883 Do not avoid creating empty evaporating overlays (Bug#9642).
12884 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12885 That is, do not delete an evaporating overlay if it becomes
12886 empty after its bounds are adjusted to fit within its buffer.
12887 This fix caused other problems, and I'm reverting it until we get
12888 to the bottom of them.
12890 2012-04-27 Chong Yidong <cyd@gnu.org>
12892 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12894 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12896 * xdisp.c (pos_visible_p): If the window start position is beyond
12897 ZV, start the display from buffer beginning. Prevents assertion
12898 violation in init_iterator when the minibuffer window is scrolled
12899 via the scroll bar.
12901 * window.c (window_scroll_pixel_based): Likewise.
12903 2012-04-27 Chong Yidong <cyd@gnu.org>
12905 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12907 2012-04-27 Glenn Morris <rgm@gnu.org>
12909 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12910 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12912 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12914 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12915 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12917 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12919 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12920 display element, check also the underlying string or buffer
12921 character. (Bug#11341)
12923 * w32menu.c: Include w32heap.h.
12924 (add_menu_item): If the call to AppendMenuW (via
12925 unicode_append_menu) fails, disable Unicode menus only if we are
12926 running on Windows 9X/Me.
12928 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12930 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12931 (xgetint): Add missing shift for LSB tags.
12933 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12935 * keyboard.c (read_char): Don't wipe echo area for select window
12936 events: These might get delayed via `mouse-autoselect-window'
12939 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12941 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12942 manipulation of :loaded-from data.
12944 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12946 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12947 now a cons (bug#11311).
12949 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12951 Do not create empty overlays with the evaporate property (Bug#9642).
12952 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12953 if it becomes empty after its bounds are adjusted to fit within
12954 its buffer. Without this fix, in a nonempty buffer (let ((o
12955 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12956 yields an empty overlay that has the evaporate property, which is
12957 not supposed to happen.
12959 Fix minor GTK3 problems found by static checking.
12960 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12961 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12962 (struct _EmacsFixedClass, emacs_fixed_get_type):

12979 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12980 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12981 (__malloc_size_t, __malloc_ptrdiff_t):
12982 Remove. All uses removed, replaced by the definiens if needed,
12983 since we can assume C89 or better now.
12984 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12992 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12993 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):

13001 Omit no-longer-needed casts.
13002 (valloc): Use getpagesize, not __getpagesize.
13003 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

13059 * alloc.c: Handle unusual debugging option combinations.
13060 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13061 since the two debugging options are incompatible.
13062 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

13072 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13074 * sysdep.c [__FreeBSD__]: Minor cleanups.
13075 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13076 Use Emacs indenting style more consistently. Avoid some casts.
13077 Use 'double' consistently rather than mixing 'float' and 'double'.
13079 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13081 * sysdep.c (list_system_processes, system_process_attributes):
13082 Add implementation for FreeBSD (Bug#5243).

13088 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13090 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13091 It is never used otherwise.
13093 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13095 * print.c (print_preprocess): Only check print_depth if print-circle
13097 (print_object): Check for cycles even when print-circle is nil and
13098 print-gensym is t, but only check print_depth if print-circle is nil.
13100 2012-04-20 Chong Yidong <cyd@gnu.org>
13102 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13103 set the status to "failed" and ensure that sentinel is run.
13105 2012-04-20 Glenn Morris <rgm@gnu.org>
13107 * process.c (Fset_process_inherit_coding_system_flag)
13108 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13116 row, return zero immediately.
13117 (try_cursor_movement): If inside continuation line, don't back up
13118 farther than the first row after the header line, if any.
13119 Don't consider the header-line row as "partially visible", even if
13120 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

13136 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13137 -Wunused-result, -Wunused-variable. This should go away once
13138 the Emacs and Gnulib regex code is merged.

13159 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13160 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13161 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13162 (NEED_MEM_INSERT): New macro.
13163 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13164 Remove one incorrect comment and fix another.

13168 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
13169 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
13170 (r_alloc_sbrk): Now static.
13172 Improve ralloc.c interface checking.
13173 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13174 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
13175 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
13176 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

13183 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13185 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13186 (struct Lisp_Misc_Any): Likewise.
13187 (struct Lisp_Free): Likewise.
13188 * alloc.c (union aligned_Lisp_Symbol): Define.

13196 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
13198 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13199 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13200 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13201 * s/netbsd.h, s/sol2-6.h:
13202 Remove definition of GC_MARK_STACK, since the default now works.
13203 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13204 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13205 no longer the default.
13206 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13208 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13210 * lread.c (lisp_file_lexically_bound_p):
13211 Fix hang at ";-*-\n" (bug#11238).
13213 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13215 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

13220 * nsterm.m (constrainFrameRect): Always constrain when there is only
13221 one screen (Bug#10962).
13223 2012-04-13 Ken Brown <kbrown@cornell.edu>

13231 2012-04-11 Daniel Colascione <dancol@dancol.org>
13233 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13234 against is gone. It's better to use vfork now so that when Cygwin
13235 gains a new, working vfork, we use it automatically (bug#10398).

13252 (force_quit_count): New var.
13253 (handle_interrupt): Use it.
13255 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13257 * w32.c (w32_delayed_load): Record the full path of the library
13258 being loaded (bug#10424).
13260 2012-04-09 Glenn Morris <rgm@gnu.org>
13262 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13263 not just in the obarray, before snarfing them. (Bug#11036)
13265 * Makefile.in ($(leimdir)/leim-list.el):
13266 Pass EMACS rather than BUILT_EMACS.
13268 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13270 * process.c (make_process):
13271 * process.h: Add integer `gnutls_handshakes_tried' member to
13274 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
13275 Add convenience `GNUTLS_LOG2i' macro.
13277 * gnutls.c (gnutls_log_function2i): Convenience log function.
13278 (emacs_gnutls_read): Use new log functions,
13279 `gnutls_handshakes_tried' process member, and
13280 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13281 attempts per process (connection).
13283 2012-04-09 Chong Yidong <cyd@gnu.org>
13285 * eval.c (Fuser_variable_p, user_variable_p_eh)

13290 * minibuf.c (Fread_variable): Callers changed.
13292 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13294 * xdisp.c (set_cursor_from_row): If the display string appears in
13295 the buffer at position that is closer to point than the position
13296 after the display string, display the cursor on the first glyph of
13297 the display string. Fixes cursor display when a 'display' text
13298 property immediately follows invisible text. (Bug#11094)
13300 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13302 composite.c: use 'double' consistently
13303 * composite.c (get_composition_id): Use 'double' consistently
13304 instead of converting 'float' to 'double' and vice versa; this is
13305 easier to understand and avoids a GCC warning.
13307 2012-04-09 Glenn Morris <rgm@gnu.org>
13309 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13310 preparation for dumping it with emacs. (Bug#4789)
13311 (leimdir): New variable.
13312 ($(leimdir)/leim-list.el): New rule.
13313 (emacs$(EXEEXT)): Depend on leim-list.el.
13315 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
13316 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
13317 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.

13329 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13331 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13332 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13333 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13334 objects, as mark_maybe_pointer will catch them otherwise.
13335 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13336 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
13338 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13340 Fix typo that broke non-Windows builds.
13341 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
13343 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13345 Support building on MS-Windows with libxml2.
13347 * makefile.w32-in (OBJ2): Add xml.$(O).
13348 (GLOBAL_SOURCES): Add xml.c.
13349 ($(BLD)/xml.$(O)): New dependency list.
13351 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13352 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13353 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13354 [!WINDOWSNT]: New macros.
13355 (init_libxml2_functions, libxml2_loaded_p): New functions.
13356 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13357 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13358 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13359 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13361 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13362 Call init_libxml2_functions before calling libxml2 functions.
13363 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13365 * emacs.c: Don't include libxml/parser.h.
13366 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13367 xmlCleanupParser directly.
13369 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13371 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13373 * indent.c (Fvertical_motion): If there is a display string at
13374 point, use it.vpos to compute how many lines to backtrack after
13375 move_it_to point. (Bug#11133)
13377 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13379 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13380 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13381 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13382 macros related to unification of CJK characters. For the details,
13383 see the discussion following the message here:
13384 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13386 2012-04-04 Chong Yidong <cyd@gnu.org>
13388 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13390 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13392 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13393 instead of alloca. (Bug#11138)
13395 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13397 * w32menu.c (is_simple_dialog): Properly check lisp types.
13400 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13402 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13403 position we get to after a call to move_it_to fails the
13404 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13405 only if we wind up in a string from display property. (Bug#11063)
13407 * window.c (Fdelete_other_windows_internal): Invalidate the row
13408 and column information about mouse highlight, so that redisplay
13409 restores it after reallocating the glyph matrices. (Bug#7464)
13411 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13412 string comes from a `display' text property, use the buffer
13413 position of that property as if we actually saw that position in
13415 (move_it_by_lines): Remove the assertion that
13416 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13417 violated when there's a before-string at the beginning of a line.
13420 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13422 * xdisp.c (append_space_for_newline): If the default face was
13423 remapped, use the remapped face for the appended newline.
13424 (extend_face_to_end_of_line): Use the remapped default face for
13425 extending the face to the end of the line.
13426 (display_line): Call extend_face_to_end_of_line when the default
13427 face was remapped. (Bug#11068)
13429 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13431 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13433 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13435 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13437 2012-03-27 Glenn Morris <rgm@gnu.org>
13439 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13442 2012-03-26 Kenichi Handa <handa@m17n.org>
13444 * dispextern.h (struct glyph): Fix previous change. Change the
13445 bit length of glyphless.ch to 25 (Bug#11082).
13447 2012-03-26 Chong Yidong <cyd@gnu.org>
13449 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13450 (command_loop_1): Use it; inhibit selection update for
13451 handle-select-window too (Bug#8996).
13453 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13455 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13457 2012-03-25 Kenichi Handa <handa@m17n.org>
13459 * dispextern.h (struct glyph): Change the bit length of
13460 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13462 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13464 * s/ms-w32.h (tzname): Include time.h before redirecting to
13465 _tzname. Fixes the MSVC build. (Bug#9960)
13467 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13469 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13472 * xterm.c (XTread_socket): Only modify handling_signal if
13473 !SYNC_INPUT. (Bug#11080)
13475 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13477 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13478 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13479 when fetching a multibyte character consumes more bytes than
13480 CHAR_BYTES returns, due to unification of CJK characters in
13481 string_char. (Bug#11073)
13483 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13485 * process.c (wait_reading_process_output): Handle pty disconnect
13486 by refraining from sending oneself a SIGCHLD (bug#10933).
13488 2012-03-22 Chong Yidong <cyd@gnu.org>

13493 Mark string as coming from a prefix property.
13494 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13495 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13497 2012-03-21 Chong Yidong <cyd@gnu.org>
13499 * xfaces.c (Vface_remapping_alist): Doc fix.
13501 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13503 * w32proc.c (Fw32_set_console_codepage)
13504 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13507 2012-03-20 Chong Yidong <cyd@gnu.org>
13509 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13510 to reflect default non-nil value of redisplay-dont-pause.
13512 2012-03-19 Kenichi Handa <handa@m17n.org>
13514 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13515 it fit in a valid range (Bug#11003).
13517 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13519 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13520 that is not from display property, accept the row as a "cursor
13521 row" if one of the string's character has a non-nil `cursor'
13522 property. Fixes cursor positioning when there are newlines in
13523 overlay strings, e.g. in icomplete.el. (Bug#11035)
13525 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13527 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13529 2012-03-12 Chong Yidong <cyd@gnu.org>
13531 * eval.c (inhibit_lisp_code): Rename from
13532 inhibit_window_configuration_change_hook; move from window.c.
13534 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13535 * window.c (run_window_configuration_change_hook)
13536 (syms_of_window): Callers changed.
13538 2012-03-11 Chong Yidong <cyd@gnu.org>
13540 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13542 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13544 2012-03-10 Chong Yidong <cyd@gnu.org>
13546 * frame.c (other_visible_frames): Don't assume the selected frame
13547 is visible (Bug#10955).
13549 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13551 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13553 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13555 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13556 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13559 2012-03-03 Glenn Morris <rgm@gnu.org>
13561 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13563 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13565 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13566 position past the first glyph_row that ends at ZV. (Bug#10902)
13567 (redisplay_window, next_element_from_string): Fix typos in
13569 (redisplay_window): Pass to move_it_vertically the margin in
13570 pixels, not in screen lines.
13572 2012-03-02 Glenn Morris <rgm@gnu.org>
13574 * buffer.c (buffer-list-update-hook): Doc fix.
13576 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13578 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13579 push_it before setting up the iterator for the first overlay
13580 string, even if we have an empty string loaded.
13581 (next_overlay_string): If there's an empty string on the iterator
13582 stack, pop the stack. (Bug#10903)
13584 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13586 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13587 Suggested by Stefan Monnier in
13588 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13589 * alloc.c (widen_to_Lisp_Object): New static function.
13590 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13591 and widening them to Lisp_Objects. This would work even if
13592 USE_LSB_TAG is defined and wide integers are used, which might
13593 happen in a future version of Emacs.
13595 2012-02-25 Chong Yidong <cyd@gnu.org>
13597 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13600 * xselect.c (Fx_selection_exists_p): Doc fix.
13601 (x_clipboard_manager_save_all): Print an informative message
13602 before saving to clipboard manager.
13604 2012-02-24 Chong Yidong <cyd@gnu.org>
13606 * keyboard.c (process_special_events): Handle all X selection
13607 requests in kbd_buffer, not just the next one (Bug#8869).
13609 2012-02-23 Chong Yidong <cyd@gnu.org>
13611 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13612 call when setting menu-bar-lines and tool-bar-lines parameters.
13613 (unwind_create_frame_1): New helper function.
13615 * window.c (inhibit_window_configuration_change_hook): New var.
13616 (run_window_configuration_change_hook): Obey it.

13626 * fileio.c (Vfile_name_handler_alist): Doc fix.
13628 * buffer.c (Fget_file_buffer): Protect against invalid file
13629 handler return value.

13633 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13634 when computing $valmask.
13636 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13637 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13638 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13639 It's useless in that case, and it can cause problems on hosts
13640 that allocate halves of EMACS_INT values separately.
13641 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13642 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13643 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13644 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13645 it avoids undefined behavior on hosts where shifting right by more
13646 than the word width has undefined behavior.
13648 2012-02-19 Chong Yidong <cyd@gnu.org>
13650 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13651 (Funhandled_file_name_directory, Ffile_name_as_directory)
13652 (Fdirectory_file_name, Fexpand_file_name)
13653 (Fsubstitute_in_file_name): Protect against invalid file handler
13654 return values (Bug#10845).
13656 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13658 * .gdbinit (pitx): Fix incorrect references to fields of the
13661 2012-02-17 Chong Yidong <cyd@gnu.org>

13665 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13667 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13668 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13670 2012-02-15 Chong Yidong <cyd@gnu.org>
13672 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13673 marked as special. Also, starting docstrings with * is obsolete.
13675 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13677 * gnutls.c (emacs_gnutls_write): Fix last change.

13686 * keymap.c (Fsingle_key_description): Handle char ranges.
13688 2012-02-12 Chong Yidong <cyd@gnu.org>
13690 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13691 as that creates a dangerous corner case.
13693 * window.c (Fdelete_window_internal): Invalidate the mouse
13694 highlight (Bug#9904).
13696 2012-02-12 Glenn Morris <rgm@gnu.org>
13698 * xselect.c (Fx_own_selection_internal)
13699 (Fx_get_selection_internal, Fx_disown_selection_internal)
13700 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13701 * nsselect.m (Fx_own_selection_internal)
13702 (Fx_disown_selection_internal, Fx_selection_exists_p)
13703 (Fx_selection_owner_p, Fx_get_selection_internal):
13704 Sync docs and argument specs with the xselect.c versions.
13706 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13708 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13710 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13712 * w32select.c (Fx_selection_exists_p): Sync doc string and
13713 argument list with xselect.c. (Bug#10783)

14263 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14264 verifies glyph row's hash code--we have just reallocated the
14265 glyphs, so their contents can be complete garbage. (Bug#10164)

14429 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14430 is set, removing the need for VIRT_ADDRESS_VARIES.
14431 (PURE_P): Use a more-efficient implementation that needs just one
14432 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14433 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14434 to 4 (xorl, subq, cmpq, setbe).
14435 * alloc.c (pure): Always extern now, since that's the

14438 consistency with the new puresize.h.
14439 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14440 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14446 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14447 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14448 behave as if the cursor position were at the window margin.
14450 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14451 and the cursor position is out of bounds, behave as if the cursor
14452 position were at the window margin. (Bug#10075)
14454 2011-11-18 Chong Yidong <cyd@gnu.org>
14456 * window.c (Fwindow_combination_limit): Make first argument

14475 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14477 * xdisp.c (row_hash): New function, body extracted from
14478 compute_line_metrics.
14479 (compute_line_metrics): Call row_hash, instead of computing the
14482 * dispnew.c (verify_row_hash): Call row_hash for computing the
14483 hash code of a row, instead of duplicating code from xdisp.c.
14485 * dispextern.h (row_hash): Add prototype.
14487 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14489 * frame.c (delete_frame): Don't delete the terminal when the last

14523 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14525 * xdisp.c (display_line): Move the call to
14526 highlight_trailing_whitespace before the call to
14527 compute_line_metrics, since the latter needs to see the final
14528 faces of all the glyphs to compute ROW's hash value.
14529 Fixes assertion violations in row_equal_p. (Bug#10035)
14531 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

14538 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14539 with user-defined heap size. Bump the default size of the temacs

14543 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14544 current_matrix and desired_matrix. (Bug#9990)
14545 (verify_row_hash) [XASSERTS]: New function.

14592 Avoid some portability problems by eschewing 'extern inline' functions.
14593 The trivial performance wins aren't worth the portability hassles; see
14594 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14596 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14662 * xmenu.c (cleanup_widget_value_tree): New function.
14663 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14664 calling free_menubar_widget_value_tree directly (Bug#9830).
14666 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14668 Fix some portability problems with 'inline'.

14670 (window_box_width, window_box_left, window_box_left_offset)
14671 (window_box_right, window_box_right_offset): Declare extern.
14672 Otherwise, these inline functions do not conform to C99 and
14673 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14674 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14675 * intervals.c (adjust_intervals_for_insertion)
14676 (adjust_intervals_for_deletion): Now extern, because otherwise the
14677 extern inline functions 'offset_intervals' couldn't refer to it.
14678 (static_offset_intervals): Remove.
14679 (offset_intervals): Rewrite using the old contents of
14680 static_offset_intervals. The old version didn't conform to C99
14681 because an extern inline function contained a reference to an
14682 identifier with static linkage.
14684 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14686 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14704 (Fwindow_vscroll): Doc fix.
14705 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14706 argument, since it makes no sense to pass a live window and for
14707 consistency with window-child.

14748 official. Move initialization of image_cache_refcount and
14749 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

14917 (w32font_open_internal, compute_metrics):
14918 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14919 instead of calling the "wide" APIs directly.

14934 * process.c (make_process): Set gnutls_state to NULL.
14936 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14937 non-NULL, regardless of GNUTLS_INITSTAGE.

14986 (bidi_resolve_weak): Don't enter the expensive loop if the current
14987 position is before next_en_pos. Record the bidi type of the first
14988 non-ET, non-BN character we find, in addition to its position.
14989 (bidi_level_of_next_char): Invalidate next_en_type when
14990 next_en_pos is over-stepped.
14992 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14994 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14995 * editfns.c: Rewrite current-time-zone so that it invokes
14996 the equivalent of (format-time-string "%Z") to get the time zone name.
14997 This fixes a bug when the time zone name contains characters that
14998 need converting from the system time locale to Emacs internal format.
14999 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15000 that patch fixed format-time-string to do the conversion, but
15001 I forgot to fix current-time-zone.
15002 (format_time_string): New function, containing most of
15003 what Fformat_time_string used to contain.
15004 (Fformat_time_string): Rewrite in terms of format_time_string.
15005 This doesn't change this function's behavior.
15006 (current-time-zone): Rewrite to use format_time_string.
15007 This fixes the bug reported by Michael Schierl in
15008 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15009 Jason Rumney's 2007-06-07 change worked around this bug, but
15011 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15013 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15015 * xdisp.c (start_display): If the character at POS is displayed
15016 via a display vector, reset IT->current.dpvec_index to zero.
15017 (try_window_reusing_current_matrix): If a line ends in a display
15018 vector or the next line starts in a display vector, continue
15019 redrawing the window even though the character position of
15020 start_row was reached.
15023 2011-10-18 Chong Yidong <cyd@gnu.org>
15025 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15026 with nobreak-char-display too.
15028 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15030 Fix part 3 of bug#9771.
15031 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15032 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15033 non-neutral characters if the current character is a paragraph
15034 separator (a.k.a. Newline). This avoids running the same
15035 expensive loop twice, once when we consume the preceding newline
15036 and the other time when the line actually needs to be displayed.
15037 Avoid the loop when we see neutrals on the base embedding level
15038 following a character whose directionality is the same as the
15039 paragraph's. This avoids running the expensive loop when a line
15040 ends in a long sequence of neutrals, like control characters.
15041 Add assertion against STRONG_AL type. Slightly rearrange code
15042 that determines the type of a neutral given the first non-neutral
15044 (bidi_level_of_next_char): Set next_en_pos to zero when
15045 invalidating its info.
15047 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15049 * xdisp.c (push_display_prop): Determine whether to record string
15050 or buffer position by IT->string, not by IT->method. Allow
15051 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15052 (move_it_vertically_backward): Don't look for character position
15053 immediately after the newline when in a continuation line.
15056 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15058 * window.c (coordinates_in_window): Rewrite and delabelize
15059 vertical border check. (Bug#5357) (Bug#9618)

15063 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained

15068 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15069 avoid crash when xmalloc overrun checking is enabled.
15071 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15073 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15074 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15075 cursor motion with <left> and <right> arrow keys.
15077 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15078 some callers set that themselves.
15080 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15082 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15083 display string and the previous row comes from the same string and
15084 is empty. (Bug#9739) (Bug#9738)
15086 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15088 * doc.c (get_doc_string): Encode file name (bug#9735).
15090 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15092 * bidi.c (bidi_level_of_next_char):
15093 * xdisp.c (get_visually_first_element): Remove old incorrect
15094 comments regarding the Unicode Line Separator character.
15096 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15098 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

15104 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15106 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15107 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15109 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15110 Some packages use them to denote characters with modifiers.
15112 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15114 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15115 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15116 matching a pp-number. Rename parameter var to var1.
15118 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15120 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15122 2011-10-08 Glenn Morris <rgm@gnu.org>
15124 * callint.c (Fcall_interactively): Give a more explicit error for the
15125 'c' case with a non-character input. (Bug#8479)
15127 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15129 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15131 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15132 lines that are hscrolled on the left.
15134 * dispnew.c (buffer_posn_from_coords): Account for a possible
15135 presence of header-line. (Bug#4426)
15137 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15139 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15140 Don't advertise functionality which we discourage or doesn't work.
15142 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15144 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15145 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15146 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15147 this makes Emacs dump core during garbage collection on rare
15148 occasions. sizeof is obviously inferior to offsetof here, so
15149 stick with offsetof.
15150 (GC_POINTER_ALIGNMENT): New macro.
15151 (mark_memory): Omit 3rd (offset) arg; caller changed.
15152 Don't assume EMACS_INT alignment is the same as pointer alignment.
15154 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15156 * keyboard.c (read_key_sequence_remapped): New var.
15157 (read_key_sequence): Compute remapping in the right buffer.
15158 (command_loop_1): Use read_key_sequence's remapping directly.
15160 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15162 * dired.c (file_name_completion): Don't expand file name.
15163 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15164 before checking file name handler.
15166 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15167 they've been requested explicitly (bug#9591).
15169 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15171 * keymap.c (Fsingle_key_description): Use make_specified_string
15172 instead of build_string to build string from push_key_description.
15175 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15177 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15178 This fixes a Y2038 bug on 64-bit hosts.
15179 * buffer.c (reset_buffer):
15180 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15181 (Fclear_buffer_auto_save_failure):
15182 Use 0, not -1, to represent an unset failure time, since time_t
15183 might not be signed.
15185 Remove dependency on glibc malloc internals.
15186 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15187 Move back here from lisp.h, but with their new implementations.
15188 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15189 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15190 * charset.c (charset_table_init): New static var.
15191 (syms_of_charset): Use it instead of xmalloc. This removes a
15192 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15193 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15194 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15195 Move back to alloc.c.
15196 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15197 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15199 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15201 * nsterm.m (windowDidResize): Call x_set_window_size only when
15202 ns_in_resize is true. Otherwise set pixelwidth/height and
15203 call change_frame_size (Bug#9628).
15205 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15207 Port --enable-checking=all to Fedora 14 x86-64.
15208 * charset.c (syms_of_charset): Also account for glibc malloc's
15209 internal overhead when calculating the initial malloc maximum.
15211 Port --enable-checking=all to Fedora 14 x86.
15212 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15214 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15215 (overrun_check_realloc, overrun_check_free):
15216 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15217 That way, xmalloc returns a properly-aligned pointer even if
15218 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15219 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15220 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15221 into account when calculating the initial malloc maximum.
15222 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15223 Move here from alloc.c, so that charset.c can use it too.
15224 Properly align; the old code wasn't right for common 32-bit hosts
15225 when configured with --enable-checking=all.
15226 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15227 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15229 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15231 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15234 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15236 * xdisp.c (compute_display_string_end): If there's no display
15237 string at CHARPOS, return -1.
15239 * bidi.c (bidi_fetch_char): When compute_display_string_end
15240 returns a negative value, treat the character as a normal
15241 character not covered by a display string. (Bug#9624)
15243 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15245 * lread.c (Fread_from_string): Fix typo in docstring.
15247 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15249 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15250 newline, reseat the iterator instead of bidi-iterating there one
15251 character at a time. (Bug#9610)
15252 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15253 TO_CHARPOS if the bidi iterator is at base embedding level.
15255 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15257 * lread.c (readevalloop): Use correct code for NBSP.
15258 (read1): Likewise. (Bug#9608)
15260 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15262 * dbusbind.c (Fdbus_register_signal): When service is not
15263 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15265 2011-09-25 Glenn Morris <rgm@gnu.org>
15267 * buffer.c (truncate-lines): Doc fix.
15269 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15271 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15272 (Fset_window_next_buffers): Doc fix.
15274 2011-09-24 Glenn Morris <rgm@gnu.org>
15276 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15278 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15280 Fix minor problems found by static checking.
15281 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15282 * indent.c (Fvertical_motion): Fix == vs = typo.
15284 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15286 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15287 Default value is now t. Doc fix.
15289 * indent.c (Fvertical_motion): Compute and apply the overshoot
15290 logic when moving up, not only when moving down. Fix the
15291 confusing name and values of the it_overshoot_expected variable;
15292 logic changes accordingly. (Bug#9254) (Bug#9549)
15294 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15295 CHARPOS is covered by a display string which includes newlines.
15296 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15297 is covered by a display string with embedded newlines.
15299 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15301 * dbusbind.c (Fdbus_register_signal): Add match rule to
15302 Vdbus_registered_objects_table. (Bug#9581)
15303 (Fdbus_register_method, Vdbus_registered_objects_table):
15306 2011-09-24 Jim Meyering <meyering@redhat.com>
15308 do not ignore write error for any output size
15309 The previous change was incomplete.
15310 While it makes emacs --batch detect the vast majority of stdout
15311 write failures, errors were still ignored whenever the output size is
15312 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15313 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15314 && echo FAIL: ignored write error
15315 FAIL: ignored write error
15316 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15317 && echo FAIL: ignored write error
15318 FAIL: ignored write error
15319 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15321 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15323 * emacs.c (Fkill_emacs): In noninteractive mode exit
15324 non-successfully if a write error occurred on stdout. (Bug#9574)
15326 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15328 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15331 * dispextern.h (struct it): Update the comment documenting what
15334 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15336 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15337 a display string, extend search for cursor position to end of row.
15338 (find_row_edges): If the row ends in a newline from a display
15339 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15340 Handle the case of a display string with multiple newlines.
15341 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15342 non-empty line. Fixes confusing cursor motion with arrow keys at
15343 the beginning of a line that starts with whitespace.
15345 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15347 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15350 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15352 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15353 boolean (Bug#9154).
15355 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15357 * xdisp.c (display_line): Record maximum and minimum buffer
15358 positions even if no glyphs were produced (e.g., by a zero-width
15359 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15360 buffer positions that will be removed from the glyph row because
15362 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15363 column is beyond frame width: don't subtract 1 "pixel" when
15364 computing width of the stretch.
15365 (reseat_at_next_visible_line_start): Undo the change made on
15366 2011-09-17 that saved paragraph information and restored it after
15367 the call to `reseat'. (Bug#9545)
15369 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15371 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15372 and turn window cursor on if cleared (Bug#9415).
15374 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15376 * search.c (boyer_moore): Take unibyte characters from pattern
15377 literally. (Bug#9458)
15379 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15381 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15383 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15385 Fix minor problem found by static checking.
15386 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15387 initialized, to pacify gcc -Wuninitialized.
15389 * fileio.c: Report proper errno when syscall falls.
15390 (Finsert_file_contents): Save and restore errno,
15391 so that report_file_error outputs the correct diagnostic.
15392 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15394 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15396 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15398 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15400 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15401 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15403 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15405 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15406 about the current paragraph and restore it after the call to reseat.
15408 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15409 (bidi_find_paragraph_start): Search back for paragraph beginning
15410 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15411 (bidi_move_to_visually_next): Only trigger paragraph-related
15412 computations when the last character is a newline or at EOB, not
15413 just any NEUTRAL_B. (Bug#9470)
15415 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15416 truncated lines if point is covered by a display string. (Bug#9524)
15418 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15420 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15421 (cons_to_x_long): New function.
15422 (lisp_data_to_selection_data): Use it. Correct the test for
15423 short-versus-long data; it was negated. Break out of vector
15424 loop, for efficiency, when a long datum is discovered.
15426 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15428 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15430 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15432 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15433 GCC PR/17406) by declaring this function with external scope.
15435 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15437 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15438 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15440 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15442 * editfns.c (Fformat): Correctly handle text properties on "%%".
15444 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15446 * xterm.c (x_draw_composite_glyph_string_foreground):
15447 * w32term.c (x_draw_composite_glyph_string_foreground):
15448 * term.c (encode_terminal_code):
15449 * composite.c (composition_update_it, get_composition_id):
15450 * xdisp.c (get_next_display_element)
15451 (fill_composite_glyph_string): Add comments about special meaning
15452 of TAB characters in a composition.
15454 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15456 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15457 This occurs when processing a multibyte format.
15458 Problem reported by Wolfgang Jenker.
15460 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15462 * xdisp.c (try_cursor_movement): Only check for exact match if
15463 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15465 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15467 Remove unused external symbols.
15468 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15469 * xdisp.c (calc_pixel_width_or_height): Now static.
15470 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15471 * indent.c (check_display_width):
15472 * w32term.c: Fix comment to match code.
15473 * xterm.c, xterm.h (x_catching_errors): Remove.
15475 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15477 * xselect.c: Use signed conversions more consistently (Bug#9498).
15478 (selection_data_to_lisp_data): Assume incoming selection data are
15479 signed integers, not unsigned. This is to be consistent with
15480 outgoing selection data, which was modified to use signed integers
15481 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15482 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15483 expects long, not unsigned long.
15485 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15487 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15488 computation of loop end. Reported by Johan Bockgård
15491 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15493 * frame.c (Fother_visible_frames_p): Function deleted.
15495 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15497 * indent.c (compute_motion): Process display vector front to back
15498 rather than the other way around. (Bug#2496)
15500 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15502 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15504 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15506 * minibuf.c (Fread_from_minibuffer): Doc fix.
15508 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15510 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15511 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15513 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15515 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15516 value for non-existent files.
15518 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15520 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15521 set its "size" to -1. This will set the modtime_size field of
15522 the corresponding buffer to -1, which is what
15523 verify-visited-file-modtime expects for files that do not exist.
15526 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15528 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15530 * lisp.h: ... from here. push_key_description is no longer
15531 defined in keyboard.c, so its declaration should not be in
15532 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15533 logically belongs with push_key_description.
15535 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15537 * buffer.h: Include <sys/types.h> instead of <time.h>.
15538 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15539 Problem reported by Herbert J. Skuhra.
15541 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15543 * xml.c (parse_region): Make the parsing work for
15544 non-comment-starting XML files again (bug#9144).
15546 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15548 * image.c (gif_load): Fix calculation of bottom and right corner.
15551 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15553 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15554 redisplay in small windows.
15556 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15558 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15560 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15562 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15563 Operate on live windows only.
15565 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15567 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15569 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15571 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15572 only under bidi iteration.
15574 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15576 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15578 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15580 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15581 Without this fix, the command to link temacs failed due to an
15582 undefined symbol __builtin_isnan. This is because
15583 /usr/include/iso/math_c99.h #defines isnan(x) to
15584 __builtin_isnan(x), but the bundled gcc, which identifies itself
15585 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15587 * floatfns.c (isnan): #undef, and then #define to a clone of
15589 (Fisnan): Always define, since it's always available now.
15590 (syms_of_floatfns): Always define isnan at the Lisp level.
15592 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15594 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15596 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15598 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15599 The previous code assumed that file offsets (off_t values) fit in
15600 EMACS_INT variables, which is not true on typical 32-bit hosts.
15601 The code messed up by falsely reporting buffer overflow in cases
15602 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15603 when "big" contains more than 2**29 bytes, even though this
15604 inserts just one byte and does not overflow the buffer.
15605 (Finsert_file_contents): Store file offsets as off_t
15606 values, not as EMACS_INT values. Check for overflow when
15607 converting between EMACS_INT and off_t. When checking for
15608 buffer overflow or for overlap, take the offsets into account.
15609 Don't use EMACS_INT for small values where int suffices.
15610 When checking for overlap, fix a typo: ZV was used where
15611 ZV_BYTE was intended.
15612 (Fwrite_region): Don't assume off_t fits into 'long'.
15613 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15615 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15617 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15619 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15621 sprintf-related integer and memory overflow issues (Bug#9412).
15623 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15624 (esprintf, exprintf, evxprintf): New functions.
15625 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15626 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15627 (modify_event_symbol): Do not assume that the length of
15628 name_alist_or_stem is safe to alloca and fits in int.
15629 (Fexecute_extended_command): Likewise for function name and binding.
15630 (Frecursion_depth): Wrap around reliably on integer overflow.
15631 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15632 since some callers pass EMACS_INT values.
15633 (Fsingle_key_description): Don't crash if symbol name contains more
15634 than MAX_ALLOCA bytes.
15635 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15636 (get_minibuffer): Arg is now EMACS_INT, not int.
15637 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15638 (esprintf, exprintf, evxprintf): New decls.
15639 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15641 * dbusbind.c (signature_cat): New function.
15642 (xd_signature, Fdbus_register_signal):
15643 Do not overrun buffer; instead, report string overflow.
15645 * dispnew.c (add_window_display_history): Don't overrun buffer.
15646 Truncate instead; this is OK since it's just a log.
15648 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15649 even if the time zone offset is outlandishly large.
15650 Don't mishandle offset == INT_MIN.
15652 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15653 when creating daemon; the previous buffer-overflow check was incorrect.
15655 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15656 which has the guts of the old verror function.
15658 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15659 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15661 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15662 (font_unparse_xlfd): Don't blindly alloca long strings.
15663 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15664 fits in int, when using sprintf. Use single snprintf to count
15665 length of string rather than counting it via multiple sprintfs;
15666 that's simpler and more reliable.
15667 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15668 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15669 sprintf, in case result does not fit in int.
15671 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15672 (fontset_from_font): Print it.
15674 * frame.c (tty_frame_count): Now printmax_t, not int.
15675 (make_terminal_frame, set_term_frame_name): Print it.
15676 (x_report_frame_params): In X, window IDs are unsigned long,
15677 not signed long, so print them as unsigned.
15678 (validate_x_resource_name): Check for implausibly long names,
15679 and don't assume name length fits in 'int'.
15680 (x_get_resource_string): Don't blindly alloca invocation name;
15681 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15684 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15685 (xg_check_special_colors, xg_set_geometry):
15686 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15688 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15689 Use esprintf, not sprintf, in case result does not fit in int.
15691 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15692 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15693 it as a large positive number.
15694 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15695 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15697 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15698 in case result does not fit in int.
15700 * print.c (float_to_string): Detect width overflow more reliably.
15701 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15702 buffer overrun. Don't assume list length fits in 'int'. Treat
15703 print length of 0 as 0, not as infinity; to be consistent with other
15704 uses of print length in this function. Don't overflow print length
15705 index. Don't assume hash table size fits in 'long', or that
15706 vectorlike size fits in 'unsigned long'.
15708 * process.c (make_process): Use printmax_t, not int, to format
15709 process-name gensyms.
15711 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15713 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15714 to avoid potential buffer overrun.
15716 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15717 if X resource line is longer than 512 bytes.
15719 * xfns.c (x_window): Make sprintf buffer a bit bigger
15720 to avoid potential buffer overrun.
15722 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15724 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15726 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15728 Integer overflow fixes for scrolling, etc.
15729 Without these, Emacs silently mishandles large integers sometimes.
15730 For example, "C-u 4294967297 M-x recenter" was treated as if
15731 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15733 * xdisp.c (try_window_id): Check Emacs fixnum range before
15734 converting to 'int'.
15736 * window.c (window_scroll_line_based, Frecenter):
15737 Check that an Emacs fixnum is in range before assigning it to 'int'.
15738 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15739 values converted from Emacs fixnums.
15740 (Frecenter): Don't wrap around a line count if it is out of 'int'
15741 range; instead, treat it as an extreme value.
15742 (Fset_window_configuration, compare_window_configurations):
15743 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15745 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15746 that can exceed INT_MAX. Check that EMACS_INT value is in range
15747 before assigning it to the (possibly-narrower) index.
15748 (match_limit): Don't assume that a fixnum can fit in 'int'.
15750 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15753 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15754 (Fvertical_motion): Don't wrap around LINES values that don't fit
15755 in 'int'. Instead, treat them as extreme values. This is good
15756 enough for windows, which can't have more than INT_MAX lines anyway.
15758 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15760 * Require libxml/parser.h to avoid compilation warning.
15762 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15764 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15765 since this reportedly can destroy thread storage.
15767 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15769 * syntax.c (find_defun_start): Update all cache variables if
15770 exiting early (Bug#9401).
15772 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15774 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15776 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15777 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15778 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15780 * term.c (tty_append_glyph): New function.
15781 (produce_stretch_glyph): Static function and its prototype deleted.
15783 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15786 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15788 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15789 when checking :margin (Bug#9390).
15790 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15791 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15792 so that the name doesn't mislead. All uses changed.
15794 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15796 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15799 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15801 * xdisp.c (move_it_to): Don't bail out early when reaching
15802 position beyond to_charpos, if we are scanning backwards.
15803 (move_it_vertically_backward): When DY == 0, make sure we get to
15804 the first character in the line after the newline.
15806 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15808 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15809 (ccl_driver): Do not generate an out-of-range pointer.
15810 (Fccl_execute_on_string): Remove unnecessary check for
15811 integer overflow, noted by Stefan Monnier in
15812 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15813 Remove a FIXME that didn't need fixing.
15814 Simplify the newly-introduced buffer reallocation code.
15816 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15818 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15820 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15822 Integer and memory overflow issues (Bug#9196).
15824 * doc.c (get_doc_string): Rework so that
15825 get_doc_string_buffer_size is the actual buffer size, rather than
15826 being 1 less than the actual buffer size; this makes xpalloc more
15829 * image.c (x_allocate_bitmap_record, cache_image):
15830 * xselect.c (Fx_register_dnd_atom):
15831 Simplify previous changes by using xpalloc.
15833 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15834 since either will do and ptrdiff_t is convenient with xpalloc.
15836 * charset.c (charset_table_size)
15837 (struct charset_sort_data.priority): Now ptrdiff_t.
15838 (charset_compare): Don't overflow if priorities differ greatly.
15839 (Fsort_charsets): Don't assume list length fits in int.
15840 Check for size-calculation overflow when allocating sort data.
15841 (syms_of_charset): Allocate an initial charset table that is
15842 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15844 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15846 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15847 The actual value is always <= INT_MAX, and leaving it unsigned made
15848 overflow checking harder.
15850 * dispextern.h (struct glyph_matrix.rows_allocated)
15851 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15852 with xpalloc. The values are still always <= INT_MAX.
15854 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15856 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15857 (SAFE_NALLOCA): New macro.
15859 * region-cache.c (struct boundary.pos, find_cache_boundary)
15860 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15861 (set_cache_region, invalidate_region_cache)
15862 (revalidate_region_cache, know_region_cache, region_cache_forward)
15863 (region_cache_backward, pp_cache):
15864 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15865 so that ptrdiff_t * can be passed to xpalloc.
15866 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15867 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15868 (pp_cache): Don't assume cache_len fits in int.
15869 * region-cache.h: Adjust extern decls to match.
15871 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15872 EMACS_INT, since either will do, for xpalloc.
15874 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15875 (xnmalloc, xnrealloc, xpalloc): New functions.
15877 * bidi.c (bidi_shelve_header_size): New constant.
15878 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15879 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15881 * bidi.c (bidi_cache_shrink):
15882 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15884 Don't update size of array until after memory allocation succeeds,
15885 because xmalloc/xrealloc may not return.
15886 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15887 now that we have proper integer overflow checking.
15888 (record_overlay_string, overlay_strings): Catch overflows when
15889 calculating size of overlay_str_buf.
15891 * callproc.c (Fcall_process): Check for size overflow when
15892 calculating size of args2.
15893 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15894 Normally we prefer signed values, but sticking with ptrdiff_t would
15895 require adding more-complicated checks.
15897 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15898 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15899 Redo buffer-overflow calculations to avoid integer overflow.
15900 Add a FIXME comment where memory seems to be over-allocated.
15902 * character.c (Fstring): Check for size-calculation overflow.
15904 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15905 unnecessary integer overflow. Check for size overflow.
15906 (encode_coding_object): Don't update size until xmalloc succeeds.
15908 * composite.c (get_composition_id): Check for overflow in glyph
15909 length calculations.
15911 Integer and memory overflow fixes for display code.
15912 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15913 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15914 (scrolling_window): Check for overflow in size calculations.
15915 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15916 Don't assume glyph table len fits in int.
15917 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
15918 (row_table_size): Now ptrdiff_t, not int.
15919 (scrolling_window): Avoid overflow in size calculations.
15920 Don't update size until allocation succeeds.
15921 * fns.c (concat): Check for overflow in size calculations.
15922 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15923 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15924 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15926 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15927 (get_doc_string): Check for size calculation overflow.
15928 Don't update size until allocation succeeds.
15929 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15930 EMACS_INT, where ptrdiff_t will do.
15931 (Fsubstitute_command_keys): Check for string overflow.
15933 * editfns.c (set_time_zone_rule): Don't assume environment length
15935 (message_length): Now ptrdiff_t, not int.
15936 (Fmessage_box): Don't update size until allocation succeeds.
15937 Don't assume message length fits in int.
15938 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15940 * emacs.c (main): Do not reallocate argv, since there is a null at
15941 the end that can be overwritten, and this way there's no need to
15942 worry about size-calculation overflow.
15943 (sort_args): Check for size-calculation overflow.
15945 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15947 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15949 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15950 (x_set_scroll_bar_width, x_figure_window_size):
15951 Check for integer overflow.
15952 (x_set_alpha): Do not assume XINT fits in int.
15954 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15955 This is for the members text_lines, text_cols, total_lines, total_cols,
15956 where the system imposes an 'int' limit.
15958 * fringe.c (Fdefine_fringe_bitmap):
15959 Don't update size until alloc works.
15961 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15962 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15964 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15965 Check for size-calculation overflow.
15966 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15967 do, as we prefer signed integers.
15968 (id_to_widget.max_size, id_to_widget.used)
15969 (xg_store_widget_in_map, xg_remove_widget_from_map)
15970 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15971 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15972 Use and return ptrdiff_t, not int.
15973 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15974 * gtkutil.h: Change prototypes to match the above.
15976 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15977 are duplicate now that they've been promoted to lisp.h.
15978 (x_allocate_bitmap_record, x_alloc_image_color)
15979 (make_image_cache, cache_image, xpm_load):
15980 Don't update size until alloc is done.
15981 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15983 Check for size calculation overflow.
15984 (ct_colors_allocated_max): New constant.
15985 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15988 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15989 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15990 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15991 Use ptrdiff_t, not int, to count maps.
15992 (read_char_minibuf_menu_prompt): Check for overflow in size
15993 calculations. Don't update size until allocation succeeds.
15994 Redo calculations to avoid overflow.
15995 * keyboard.h: Change prototypes to match the above.
15997 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15999 (current_minor_maps): Check for size calculation overflow.
16000 * keymap.h: Change prototypes to match the above.
16002 * lread.c (read1, init_obarray): Don't update size until alloc done.
16004 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
16005 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
16007 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
16008 Now ptrdiff_t, not int.
16009 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

16021 (Fset_match_data): Don't assume list lengths fit in 'int'.
16023 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16024 for command line length. Do not attempt to address one before the
16025 beginning of an array, as that's not portable.
16027 * term.c (max_frame_lines): Remove; unused.
16028 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16030 (encode_terminal_code, calculate_costs): Check for size
16031 calculation overflow.

16035 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16037 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16038 subtracting pointers.

16053 Use ptrdiff_t, not int, for sizes.
16054 (Finternal_make_lisp_face, cache_face):
16055 Check for size calculation overflow.
16056 (cache_face): Treat size calculation overflows as if they were
16057 memory exhaustion (the usual treatment), rather than aborting.
16059 * xfns.c (x_encode_text, x_set_name_internal)
16060 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16061 sizes, since they can exceed INT_MAX in size. Check for size
16062 calculation overflow.
16064 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16065 (xg_select): Check for size calculation overflow.
16066 Don't update size until alloc done.
16068 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16069 as sprintf is limited to int lengths.
16071 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16072 (X_LONG_MIN): New macros.
16073 Use them to make the following changes clearer.
16074 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16075 This change doesn't affect the value now, but it may help remind
16076 future maintainers not to raise the value too much later.
16077 (SELECTION_QUANTUM): Remove, replacing with ...
16078 (selection_quantum): ... new function, which avoids overflow.
16080 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16081 assumption that selection length fits in 'int'.
16082 (x_reply_selection_request, x_handle_selection_request)
16083 (x_get_window_property, receive_incremental_selection)

16088 (receive_incremental_selection, x_property_data_to_lisp):
16089 Redo calculations to avoid overflow.
16090 (x_reply_selection_request): When sending hint, ceiling it at

16094 (lisp_data_to_selection_data, x_property_data_to_lisp):
16095 Check for size-calculation overflow.

16098 Don't store size until memory allocation succeeds.
16099 (x_get_window_property): Plug memory leak on memory exhaustion.
16100 Don't double-block input; malloc is safe here. Don't assume 2**34
16101 - 4 fits in unsigned long. Add an xassert to check
16102 XGetWindowProperty overflow. Be more careful about overflow
16103 calculations, and distinguish size from memory overflow better.
16104 (receive_incremental_selection): When tracing, don't assume
16105 unsigned int is less than INT_MAX.
16106 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16107 harmful) conversions of unsigned short to int.
16108 (lisp_data_to_selection_data): Don't assume that integers
16109 in the range -65535 through -1 fit in an X unsigned short.
16110 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16111 result parameters unless successful. Rely on cons_to_unsigned
16112 to report problems with elements; the old code wasn't right anyway.
16113 (x_check_property_data): Check for int overflow; we cannot use
16114 a wider type due to X limits.
16115 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16117 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16119 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)

16147 * lisp.h (hash_lookup, hash_put):
16148 * minibuf.c (Ftest_completion):
16149 Use ptrdiff_t for hash table indexes, not int (which is too
16150 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16151 32-bit --with-wide-int hosts).
16153 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16154 Add a FIXME comment about memory leaks.
16155 (syms_of_charset): Don't assume xmalloc returns.

16162 with outlandish widths.
16163 * character.h (sanitize_tab_width): Rename from sanitize_width,
16164 now that we have two such functions. All uses changed.

16182 * xterm.c: Don't go over XClientMessageEvent limit.
16183 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16184 (x_send_scroll_bar_event): Likewise. Check that the size does not
16185 exceed limits imposed by XClientMessageEvent, as well as the usual
16186 ptrdiff_t and size_t limits.
16188 * keyboard.c: Overflow, signedness and related fixes.
16189 (make_lispy_movement): Use same integer type in forward decl
16190 that is used in the definition.
16191 (read_key_sequence, keyremap_step):
16192 Change bufsize argument back to int, undoing my 2011-03-30 change.
16193 We prefer signed types, and int is wide enough here.
16194 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16195 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16196 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16197 length, not size_t. Use ptrdiff_t for index, not int.
16198 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16199 possibility of integer overflow.
16201 Overflow, signedness and related fixes for images.

16223 (lookup_image): Remove unnecessary tests.
16224 (xbm_image_p): Locals are now of int, not EMACS_INT,
16225 since parse_image_check makes sure they fit into int.
16226 (png_load, gif_load, svg_load_image):
16227 Prefer int to unsigned where either will do.
16228 (tiff_handler): New function, combining the cores of the
16229 old tiff_error_handler and tiff_warning_handler.
16230 This function is rewritten to use vsnprintf and thereby avoid
16231 stack buffer overflows. It uses only the features of vsnprintf
16232 that are common to both POSIX and native Microsoft.
16233 (tiff_error_handler, tiff_warning_handler): Use it.
16234 (tiff_load, gif_load, imagemagick_load_image):
16235 Don't assume :index value fits in 'int'.
16236 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16237 (imagemagick_load_image): Check that crop parameters fit into
16238 the integer types that MagickCropImage accepts. Don't assume
16239 Vimagemagick_render_type has a nonnegative value. Don't assume
16240 size_t fits in 'long'.
16241 (gs_load): Use printmax_t to print the widest integers possible.
16242 Check for integer overflow when computing image height and width.

16254 handle_single_display_spec, not just 1 or zero.
16255 (handle_single_display_spec): If the display spec is of the form
16256 `(space ...)', and specifies display in the text area, return 2
16258 (try_cursor_movement): Check for the need to scroll more
16259 accurately, and prefer exact match for point under bidi.
16260 Don't advance `row' beyond the last row of the window.

16277 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16278 buffers, return left-to-right.
16279 (set_cursor_from_row): Consider candidate row a win if its glyph
16280 represents a newline and point is on that newline. Fixes cursor
16281 positioning on the newline at EOL of R2L text within L2R
16282 paragraph, and vice versa.
16283 (try_cursor_movement): Check continued rows, in addition to
16284 continuation rows. Fixes unwarranted scroll when point enters a
16285 continued line of R2L text within an L2R paragraph, or vice versa.
16286 (cursor_row_p): Consider the case of point being equal to
16287 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16288 from the end of a short line to the beginning of a continued line
16289 of R2L text within L2R paragraph.

16316 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16317 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16318 candidate is selected by the mouse, and that candidate has a
16319 composed character under the mouse.
16321 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16322 coordinates reported by pos-visible-in-window-p for a composed
16323 character in column zero.
16325 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16331 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16332 consider it a hit if to_charpos is anywhere in the range of the
16333 composed buffer positions.
16335 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16337 * image.c (gif_load): Don't assume that each subimage has the same
16338 dimensions as the base image. Handle disposal method that is
16339 "undefined" by the gif spec (Bug#9335).
16341 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16343 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16353 a composition, take its buffer position from IT->cmp_it.charpos.
16354 Fixes cursor positioning at the beginning of a line that begins
16355 with a composed character.
16357 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16359 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16360 character bidirectional type, use STRONG_L instead. Fixes crashes
16361 in a buffer produced by `describe-categories'.
16363 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16364 members before the level stack, so they would be saved and
16365 restored when copying iterator state. Fixes incorrect reordering
16366 around TABs covered by display properties.

16394 Fix memory allocation problems in Cygwin build (Bug#9273).
16396 * unexcw.c ( __malloc_initialized): Declare external variable.
16397 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16399 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16401 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16440 * xdisp.c (move_it_in_display_line_to): Don't invoke
16441 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16442 ppos_it. Fixes vertical cursor motion when line beginning is
16443 covered by an image. (Bug#9296)
16445 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>

16454 the event loop. Get status from as_status (Bug#7276).
16456 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16457 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16458 the event loop (Bug#7276).
16460 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16462 * gnutls.c (QCgnutls_bootprop_priority)
16463 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16464 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16465 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16466 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16467 (QCgnutls_bootprop_verify_hostname_error)
16468 (QCgnutls_bootprop_callbacks_verify): Rename from
16469 Qgnutls_bootprop_..., all uses changed.
16471 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16474 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16476 * xfaces.c (Qframe_set_background_mode): Now static.
16477 * dispextern.h (Qframe_set_background_mode): Remove decl.
16479 * process.c (Fnetwork_interface_info): Declare local only if needed.
16481 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16483 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16484 (Fnetwork_interface_list): Allocate in increments of bytes instead
16485 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16486 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16488 (struct ifflag_def): notrailers is smart on OSX.
16489 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16490 Get hardware address with getifaddrs if available.
16492 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16494 * xdisp.c (iterate_out_of_display_property): xassert that
16495 IT->position is set to within IT->object's boundaries. Break from
16496 the loop as soon as EOB is reached; avoids infloops in redisplay
16497 when IT->position is set up wrongly due to some bug.
16498 Set IT->current to match the bidi iterator unconditionally.
16499 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16500 entry. Force push_it to save on the stack the current
16501 buffer/string position, to be restored by pop_it. Fix flags in
16502 the iterator structure wrt the object coming from a display
16503 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16504 properties. (Bug#9284)
16506 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16508 * fontset.c (fontset_get_font_group): Add proper type checks.
16511 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16513 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16514 and LC_VERSION_MIN_MACOSX.
16515 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16516 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16518 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16520 * xdisp.c (forward_to_next_line_start): Allow to use the
16521 no-display-properties-and-no-overlays under bidi display.
16522 Set disp_pos in the bidi iterator to avoid searches for display
16523 properties and overlays.
16525 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16527 * editfns.c (Fset_time_zone_rule): Document relationship with the
16530 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16531 the font entity extracted from the cache (Bug#8109).
16533 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16535 * composite.c (autocmp_chars): Don't reset point. That is done by
16536 restore_point_unwind (Bug#5984).
16538 2011-08-07 Juri Linkov <juri@jurta.org>
16540 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16541 to show the arg `TIME' instead of `TIMEVAL'.
16543 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16545 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16546 display property strides EOL and includes a newline, as in
16547 longlines-mode. (Bug#9254)
16548 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16549 word-wrap under bidirectional display. (Bug#9224)
16551 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16552 is non-zero, even if the data buffer is NULL. Fixes a crash in
16553 vertical-motion with longlines-mode. (Bug#9254)
16555 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16557 * bidi.c <bidi_cache_total_alloc>: Now static.
16558 (bidi_initialize): Initialize bidi_cache_total_alloc.
16560 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16563 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16564 amount allocated this far in `bidi_cache_total_alloc'.
16565 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16566 non-zero, only free the data buffer without restoring the cache
16567 contents. All callers changed.
16569 * dispextern.h (bidi_unshelve_cache): Update prototype.
16571 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16572 (move_it_in_display_line, move_it_to)
16573 (move_it_vertically_backward, move_it_by_lines): Replace the call
16574 to xfree to an equivalent call to bidi_unshelve_cache.
16575 (move_it_in_display_line_to): Fix logic of returning
16576 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16578 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16580 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16581 came from a string character with a `cursor' property. (Bug#9229)
16583 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16585 * Makefile.in (LIB_PTHREAD): New variable.
16586 (LIBES): Add LIB_PTHREAD (Bug#9216).
16588 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16589 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16591 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16593 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16595 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16597 * xterm.c (x_find_topmost_parent): New function.
16598 (x_set_frame_alpha): Find topmost parent window with
16599 x_find_topmost_parent and set the property there also (bug#9181).
16600 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16602 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16604 * callproc.c (Fcall_process): Avoid vfork clobbering
16605 the local vars buffer, coding_systems, current_dir.
16607 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16609 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16611 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16613 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16614 so that it is not optimized away.
16616 * xdisp.c (compute_display_string_pos): Remove unused local.
16618 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16620 Fix slow cursor motion and scrolling in large buffers with
16621 selective display, like Org Mode buffers. (Bug#9218)
16623 * dispextern.h (struct bidi_it): New member disp_prop_p.
16625 * xdisp.c: Remove one-slot cache of display string positions.
16626 (compute_display_string_pos): Accept an additional argument
16627 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16628 for a display string or property. If found, set DISP_PROP_P
16631 * bidi.c (bidi_fetch_char): Accept an additional argument
16632 DISP_PROP_P, and pass it to compute_display_string_pos.
16633 Only handle text covered by a display string if DISP_PROP_P is returned
16634 non-zero. All callers of bidi_fetch_char changed.
16636 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16638 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16640 2010-12-03 Don March <don@ohspite.net>
16642 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16643 last character M-[char] is translated to ESC [char] (bug#7541).
16645 2011-08-02 Kenichi Handa <handa@m17n.org>
16647 * lisp.h (uniprop_table): Extern it.
16649 * chartab.c (uniprop_table): Make it non-static.
16651 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16653 * xdisp.c (forward_to_next_line_start): Accept additional argument
16654 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16656 (reseat_at_next_visible_line_start): Use the bidi iterator state
16657 returned by forward_to_next_line_start to restore the state of
16658 it->bidi_it after backing up to previous newline. (Bug#9212)
16660 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16662 * regex.c (re_comp): Protoize.
16663 (re_exec): Fix return type.
16664 (regexec): Fix type of `ret'. (Bug#9203)
16666 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16668 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16669 This is needed if max-image-size is a floating-point number.
16671 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16673 * print.c (print_object): Print empty symbol as ##.
16675 * lread.c (read1): Read ## as empty symbol.
16677 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16679 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16680 setting frame foreground color (Bug#9175).
16681 (x_set_background_color): Likewise.
16683 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16684 contents (Bug#9176).
16685 (EmacsTooltip -init): Remove bezels and add shadows to
16688 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16689 or scroll bar (Bug#8470).
16691 * nsfont.m (nsfont_open): Remove assignment to voffset and
16692 unnecessary vars hshink, expand, hd, full_height, min_height.
16693 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16695 * nsterm.h (nsfont_info): Remove voffset field.
16697 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16699 Implement strike-through and overline on NextStep (Bug#8863).
16701 * nsfont.m (nsfont_open): Use underline position provided by font,
16702 instead of hard-coded value of 2.
16703 (nsfont_draw): Call ns_draw_text_decoration instead.
16705 * nsterm.h: Add declaration for ns_draw_text_decoration.
16707 * nsterm.m (ns_draw_text_decoration): New function for drawing
16708 underline, overline, and strike-through.
16709 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16710 ns_draw_text_decoration. Change treatment of cursor drawing to
16711 accommodate underlining, etc.
16713 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16715 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16718 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16720 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16721 Without this fix, if a signal arrives just after memory fills up,
16722 'malloc' might be invoked reentrantly.
16724 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16725 In other words, assume that every image size is allowed, on non-X
16726 hosts. This assumption is probably wrong, but it lets Emacs compile.
16728 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16730 * regex.c (re_iswctype): Convert return values to boolean.
16732 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16734 * xdisp.c (compute_display_string_pos): Don't use cached display
16735 string position if the buffer had its restriction changed.
16738 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16740 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16742 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16744 Integer signedness and overflow and related fixes. (Bug#9079)
16746 * bidi.c: Integer size and overflow fixes.
16747 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16748 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16749 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16750 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16751 (bidi_find_other_level_edge):
16752 Use ptrdiff_t instead of EMACS_INT where either will do.
16753 This works better on 32-bit hosts configured --with-wide-int.
16754 (bidi_cache_ensure_space): Check for size-calculation overflow.
16755 Use % rather than repeated addition, for better worst-case speed.
16756 Don't set bidi_cache_size until after xrealloc returns, because it
16758 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16759 (bidi_cache_ensure_space): Also check that the bidi cache size
16760 does not exceed that of the largest Lisp string or buffer. See Eli
16761 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16763 * alloc.c (__malloc_size_t): Remove.
16764 All uses replaced by size_t. See Andreas Schwab's note
16765 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16767 * image.c: Improve checking for integer overflow.
16768 (check_image_size): Assume that f is nonnull, since
16769 it is always nonnull in practice. This is one less thing to
16770 worry about when checking for integer overflow later.
16771 (x_check_image_size): New function, which checks for integer
16772 overflow issues inside X.
16773 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16774 This removes the need for a memory_full check.
16775 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16776 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16777 (xbm_read_bitmap_data): Change locals back to 'int', since
16778 their values must fit in 'int'.
16779 (xpm_load_image, png_load, tiff_load):
16780 Invoke x_create_x_image_and_pixmap earlier,
16781 to avoid much needless work if the image is too large.
16782 (tiff_load): Treat overly large images as if
16783 x_create_x_image_and_pixmap failed, not as malloc failures.
16784 (gs_load): Use x_check_image_size.
16786 * gtkutil.c: Omit integer casts.
16787 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16788 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16790 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16792 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16793 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16794 would wrongly return t on a 64-bit host.
16796 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16797 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16798 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16799 and therefore cause GCC to emit a bogus diagnostic in some cases.
16801 * image.c: Integer signedness and overflow and related fixes.
16802 This is not an exhaustive set of fixes, but it's time to
16803 record what I've got.
16804 (lookup_pixel_color, check_image_size): Remove redundant decls.
16805 (check_image_size): Don't assume that arbitrary EMACS_INT values
16806 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16807 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16808 (tiff_load, imagemagick_load_image):
16809 Check for overflow in size calculations.
16810 (x_create_x_image_and_pixmap): Remove unnecessary test for
16811 xmalloc returning NULL; that can't happen.
16812 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16813 (xpm_color_bucket): Use better integer hashing function.
16814 (xpm_cache_color): Don't possibly over-allocate memory.
16815 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16816 (gif_memory_source):
16817 Use ptrdiff_t, not int or size_t, to record sizes.
16818 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16819 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16820 either works, as we prefer signed integers.
16821 (tiff_read_from_memory, tiff_write_from_memory):
16822 Return tsize_t, not size_t, since that's what the TIFF API wants.
16823 (tiff_read_from_memory): Don't fail simply because the read would
16824 go past EOF; instead, return a short read.
16825 (tiff_load): Omit no-longer-needed casts.
16826 (Fimagemagick_types): Don't assume size fits into 'int'.
16828 Improve hashing quality when configured --with-wide-int.
16829 * fns.c (hash_string): New function, taken from sxhash_string.
16830 Do not discard information about ASCII character case; this
16831 discarding is no longer needed.
16832 (sxhash-string): Use it. Change sig to match it. Caller changed.
16833 * lisp.h: Declare it.
16834 * lread.c (hash_string): Remove, since we now use fns.c's version.
16835 The fns.c version returns a wider integer if --with-wide-int is
16836 specified, so this should help the quality of the hashing a bit.
16838 * emacs.c: Integer overflow minor fix.
16839 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16840 Define only if GNU_LINUX.
16841 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16843 * dispnew.c: Integer signedness and overflow fixes.
16844 Remove unnecessary forward decls, that were a maintenance hassle.
16845 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16847 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16848 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16849 (prepare_desired_row, line_draw_cost):
16850 Use int, not unsigned, where either works.
16851 (save_current_matrix, restore_current_matrix):
16852 Use ptrdiff_t, not size_t, where either works.
16853 (init_display): Check for overflow more accurately, and without
16854 relying on undefined behavior.
16856 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16857 Remove, replacing with the new symbols in lisp.h. All uses changed.
16858 * fileio.c (make_temp_name):
16859 * filelock.c (lock_file_1, lock_file):
16860 * xdisp.c (message_dolog):
16861 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16862 Use pMd etc. instead.
16863 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16864 replacing the pWIDE etc. symbols removed from editfns.c.
16866 * keyboard.h (num_input_events): Now uintmax_t.
16867 This is (very slightly) less likely to mess up due to wraparound.
16870 * buffer.c: Integer signedness fixes.
16871 (alloc_buffer_text, enlarge_buffer_text):
16872 Use ptrdiff_t rather than size_t when either will do, as we prefer
16875 * alloc.c: Integer signedness and overflow fixes.
16876 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16877 (__malloc_size_t): Default to size_t, not to int.
16878 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16879 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16880 Prefer ptrdiff_t to size_t when either would do, as we prefer
16882 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16883 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16884 Now const. Initialize with values that are in range even if char
16886 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16887 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16888 These functions do the right thing with sizes > 2**32.
16889 (check_depth): Now ptrdiff_t, not int.
16890 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16891 Adjust to new way of storing sizes. Check for size overflow bugs
16893 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16894 slightly wrong anyway, as it missed one instance of
16895 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16896 (refill_memory_reserve): Omit needless cast to size_t.
16897 (mark_object_loop_halt): Mark as externally visible.
16899 * xselect.c: Integer signedness and overflow fixes.
16900 (Fx_register_dnd_atom, x_handle_dnd_message):
16901 Use ptrdiff_t, not size_t, since we prefer signed.
16902 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16903 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16904 x_dnd_atoms_size and x_dnd_atoms_length.
16906 * doprnt.c: Prefer signed to unsigned when either works.
16908 * doprnt.c (doprnt):
16910 * xdisp.c (vmessage):
16911 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16912 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16913 prefer signed arithmetic to avoid comparison confusion.
16914 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16915 but is a bit tricky.
16917 Assume freestanding C89 headers, string.h, stdlib.h.
16918 * data.c, doprnt.c, floatfns.c, print.c:
16919 Include float.h unconditionally.
16920 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16921 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16922 * regex.c: Likewise for stddef.h, string.h.
16923 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16924 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16925 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16926 (STDC_HEADERS): Remove obsolete defines.
16927 * sysdep.c: Include limits.h unconditionally.
16929 Assume support for memcmp, memcpy, memmove, memset.
16930 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16931 * regex.c (memcmp, memcpy):
16932 Remove; we assume C89 now.
16934 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16935 (__malloc_safe_bcopy): Remove; no longer needed.
16937 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16938 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16939 well either way, and we prefer signed to unsigned.
16941 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16943 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16944 closes the connection while we're reading (bug#9182).
16946 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16948 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16949 are specified (Bug#9168).
16951 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16953 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16954 Found by GCC static checking and --with-wide-int on a 32-bit host.
16956 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16958 * xdisp.c (compute_display_string_pos): Fix logic of caching
16959 previous display string position. Initialize cached_prev_pos to
16960 -1. Fixes slow-down at the beginning of a buffer.
16962 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16964 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16965 for attrs[LFACE_FONTSET_INDEX].
16967 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16969 * xml.c (parse_region): Remove unused local
16970 that was recently introduced.
16972 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16974 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16975 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16977 * xdisp.c (move_it_in_display_line_to): Record the best matching
16978 position for TO_CHARPOS while scanning the line, and restore it on
16979 exit if none of the characters scanned was an exact match.
16980 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16981 when exact match is impossible due to invisible text, and the
16982 lines are truncated.
16984 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16986 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16989 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16991 Fix a significant slow-down of cursor motion with C-n, C-p,
16992 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16993 auto-repeat under bidi redisplay in fontified buffers.
16994 * xdisp.c (compute_stop_pos_backwards): New function.
16995 (next_element_from_buffer): Call compute_stop_pos_backwards to
16996 find a suitable prev_stop when we find ourselves before
16998 (reseat): Don't look for prev_stop, as that could mean a very long
17000 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17001 <cached_disp_overlay_modiff>: Cache for last found display string
17003 (compute_display_string_pos): Return the cached position if asked
17004 about the same buffer in the same area of character positions, and
17005 the buffer wasn't changed since the time the display string
17006 position was cached.
17008 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17010 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17011 is an integer, which is important for empty lines. (Bug#9149)
17013 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17015 * frame.c (Fmodify_frame_parameters): In tty case, update the
17016 default face if necessary (Bug#4238).
17018 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17020 * editfns.c (Fstring_to_char): No need to explain what a character
17021 is in the docstring (Bug#6576).
17023 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17025 * xml.c (parse_region): Make sure we always return a tree.
17027 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17029 * xml.c (parse_region): If a document contains only comments,
17032 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17034 * xml.c (make_dom): Return comments, too.
17036 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17039 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17040 and the surrounding thread.
17041 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17042 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17043 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17045 * s/openbsd.h (BROKEN_SIGIO): Define.
17046 * unexelf.c (unexec) [__OpenBSD__]:
17047 Don't update the .mdebug section of the Alpha COFF symbol table.
17049 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17051 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17054 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17056 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17057 This fixes some race conditions on the permissions of any newly
17060 * alloc.c (valid_pointer_p): Use pipe, not open.
17061 This fixes some permissions issues when debugging.
17063 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17064 If fchown fails to set both uid and gid, try to set just gid,
17065 as that is sometimes allowed. Adjust the file's mode to eliminate
17066 setuid or setgid bits that are inappropriate if fchown fails.
17068 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17070 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17071 to compare Lisp_Objects.
17072 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17073 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17074 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17076 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17078 * lread.c (read_integer): Unread even EOF character.
17079 (read1): Likewise. Properly record start position of symbol.
17081 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17082 symbol character follows.
17084 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17086 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17087 This works around a problem with the previous change to Fcopy_file.
17088 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17089 and without this change, GCC might complain about discarding
17090 fchown's return value.
17092 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17094 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17096 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17098 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17100 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17102 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17103 it's used from the C level.
17105 * process.c: Use the same condition for POLL_FOR_INPUT in both
17106 keyboard.c and process.c (bug#1858).
17108 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17110 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17111 (Fgnutls_boot): Use it.
17113 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17115 * doc.c (Fsubstitute_command_keys): Revert last change.
17117 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17119 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17120 quotes the next character, and doesn't affect other longer
17121 sequences (bug#8935).
17123 * lread.c (syms_of_lread): Clarify that is isn't only
17124 `eval-buffer' and `eval-defun' that's affected by
17125 `lexical-binding' (bug#8460).
17127 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17129 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17130 bidi redisplay when a line includes both an image and is truncated.
17132 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17134 Fix minor problems found by static checking.
17135 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17136 (elsz): Now a signed constant, not a size_t var. We prefer signed
17137 types to unsigned, to avoid integer comparison confusion. Without
17138 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17139 "cannot optimize loop, the loop counter may overflow", a symptom
17141 * indent.c (Fvertical_motion): Mark locals as initialized.
17142 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17144 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17146 * search.c (Fre_search_backward): Mention `case-fold-search' in
17147 all the re_search_* functions (bug#8138).
17149 * keyboard.c (Fopen_dribble_file): Document when the file is

17162 bidi_it->string.schars.
17163 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17164 NULL (avoids a crash in bidi_paragraph_init).
17165 Initialize itb.string.lstring.
17166 (init_iterator): Call bidi_init_it only of a valid
17167 buffer position was specified. Initialize paragraph_embedding to
17169 (reseat_to_string): Initialize the bidi iterator.
17170 (display_string): If we need to ignore text properties of
17171 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17172 original value of -1 will not work with bidi.)
17173 (compute_display_string_pos): First arg is now struct
17174 `text_pos *'; all callers changed. Support display properties on
17176 (compute_display_string_end): Support display properties on Lisp
17178 (init_iterator, reseat_1, reseat_to_string): Initialize the
17179 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17180 when iterating on a string not from display properties).
17181 (compute_display_string_pos, compute_display_string_end):
17182 Fix calculation of the object to scan. Fixes an error when using
17184 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17185 base_level_stop; instead, set base_level_stop to BEGV.
17186 Fixes crashes in vertical-motion.
17187 (next_element_from_buffer): Improve commentary for when
17188 the iterator is before prev_stop.
17189 (init_iterator): Initialize bidi_p from the default value of
17190 bidi-display-reordering, not from buffer-local value. Use the
17191 buffer-local value only if initializing for buffer iteration.
17192 (handle_invisible_prop): Support invisible properties on strings
17193 that are being bidi-reordered.
17194 (set_iterator_to_next): Support bidi reordering of C strings and
17196 (next_element_from_string): Support bidi reordering of Lisp
17198 (handle_stop_backwards): Support Lisp strings as well.
17199 (display_string): Support display of R2L glyph rows.
17200 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17201 (init_iterator): Don't initialize it->bidi_p for strings
17203 (reseat_to_string): Initialize it->bidi_p for strings here.
17204 (next_element_from_string, next_element_from_c_string)
17205 (next_element_from_buffer): Add xassert's for correspondence
17206 between IT's object being iterated and it->bidi_it.string

17209 (next_element_from_c_string): Handle the case of the first string
17210 character that is not the first one in the visual order.
17211 (get_visually_first_element): New function, refactored from common
17212 parts of next_element_from_buffer, next_element_from_string, and
17213 next_element_from_c_string.
17214 (tool_bar_lines_needed, redisplay_tool_bar)
17215 (display_menu_bar): Force left-to-right direction. Add a FIXME
17216 comment for making that be controlled by a user option.
17217 (push_it, pop_it): Save and restore the state of the
17218 bidi iterator. Save and restore the bidi_p flag.
17219 (pop_it): Iterate out of display property for string iteration as
17221 (iterate_out_of_display_property): Support iteration over strings.
17222 (handle_single_display_spec): Set up it->bidi_it for iteration
17223 over a display string, and call bidi_init_it.
17224 (handle_single_display_spec, next_overlay_string)
17225 (get_overlay_strings_1, push_display_prop): Set up the bidi
17226 iterator for displaying display or overlay strings.
17227 (forward_to_next_line_start): Don't use the shortcut if
17229 (back_to_previous_visible_line_start): If handle_display_prop
17230 pushed the iterator stack, restore the internal state of the bidi
17231 iterator by calling bidi_pop_it same number of times.
17232 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17233 and we are bidi-iterating, don't decrement the iterator position;
17234 instead, set the first_elt flag in the bidi iterator, to produce
17236 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17237 (push_display_prop): xassert that we are iterating a buffer.
17238 (push_it, pop_it): Save and restore paragraph_embedding member.
17239 (handle_single_display_spec, next_overlay_string)
17240 (get_overlay_strings_1, reseat_1, reseat_to_string)
17241 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17242 correctly. Don't assume unibyte strings are not bidi-reordered.
17243 (compute_display_string_pos)
17244 (compute_display_string_end): Fix handling the case of C string.
17245 (push_it, pop_it): Save and restore from_disp_prop_p.

17250 popping after iteration over a string that came from a display
17251 property. Fix a typo in popping stretch info. Add an assertion
17252 for verifying that the iterator position is in sync with the bidi
17254 (handle_single_display_spec, get_overlay_strings_1)
17255 (push_display_prop): Fix initialization of paragraph direction for
17256 string when that of the parent object is not yet determined.
17257 (reseat_1): Call bidi_init_it to resync the bidi
17258 iterator with IT's position. (Bug#7616)
17259 (find_row_edges): If ROW->start.pos gives position
17260 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
17261 (handle_stop, back_to_previous_visible_line_start, reseat_1):
17262 Reset the from_disp_prop_p flag.
17263 (SAVE_IT, RESTORE_IT): New macros.

17267 (move_it_to, move_it_vertically_backward, move_it_by_lines)
17268 (try_scrolling, redisplay_window, display_line): Use them when
17269 saving a temporary copy of the iterator and restoring it back.
17270 (back_to_previous_visible_line_start, reseat_1)
17271 (init_iterator): Empty the bidi cache "stack".
17272 (move_it_in_display_line_to): If iterator ended up at
17273 EOL, but we never saw any buffer positions smaller than
17274 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
17275 motion in bidi-reordered lines.
17276 (move_it_in_display_line_to): Record prev_method and prev_pos
17277 immediately before the call to set_iterator_to_next. Fixes cursor
17278 motion in bidi-reordered lines with stretch glyphs and strings
17279 displayed in margins. (Bug#8133) (Bug#8867)
17280 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
17282 (pos_visible_p): Support positions in bidi-reordered lines.
17283 Save and restore bidi cache.
17285 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
17286 (bidi_paragraph_info): Delete unused struct.
17287 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
17288 (bidi_cache_start): New variable.
17289 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
17291 (bidi_cache_fetch_state, bidi_cache_search)
17292 (bidi_cache_find_level_change, bidi_cache_iterator_state)

17297 (bidi_fetch_char): Accept new argument STRING; all callers
17298 changed. Support iteration over a string. Support strings with
17299 display properties. Support unibyte strings. Fix the type of
17300 `len' according to what STRING_CHAR_AND_LENGTH expects.
17301 (bidi_paragraph_init, bidi_resolve_explicit_1)
17302 (bidi_resolve_explicit, bidi_resolve_weak)
17303 (bidi_level_of_next_char, bidi_move_to_visually_next):
17304 Support iteration over a string.
17305 (bidi_set_sor_type, bidi_resolve_explicit_1)
17306 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
17307 can now be zero (for strings); special values 0 and -1 were
17308 changed to -1 and -2, respectively.
17309 (bidi_char_at_pos): New function.
17310 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
17311 Call it instead of FETCH_MULTIBYTE_CHAR.

17321 (bidi_initialize): Initialize the bidi cache start stack pointer.
17322 (bidi_cache_ensure_space): New function, refactored from part of

17398 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17399 The old code sometimes used this field without initializing it.
17401 * alloc.c (gc_sweep): Don't read past end of array.
17402 In theory, the old code could also have corrupted Emacs internals,
17403 though it'd be very unlikely.

17666 (clone_per_buffer_values): Don't assume that

17668 This isn't true in general, and it's particularly not true
17669 if Emacs is configured with --with-wide-int.
17670 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17671 New macros, used in the buffer.c change.

17707 Random fixes. E.g., (random) never returned negative values.
17708 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17709 subseconds part to the entropy, as that's a bit more random.
17710 Prefer signed to unsigned, since the signedness doesn't matter and
17711 in general we prefer signed. When given a limit, use a
17712 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17713 latter isn't right if USE_2_TAGS_FOR_INTS.
17714 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17715 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17725 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17727 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17728 This is more efficient than Ffile_directory_p and avoids a minor race.
17730 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17732 * buffer.c (Foverlay_put): Say what the return value is
17735 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17736 is a directory before asking whether to use the file name
17738 (barf_or_query_if_file_exists): Make the "File is a directory"
17739 error be more correct.
17741 * fns.c (Frequire): Remove the mention of the .gz files, since
17742 that's installation-specific, but keep the mention of
17743 `get-load-suffixes'.

17747 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17755 Qgnutls_bootprop_verify_error (which is no longer used).
17757 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17758 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17759 Also (re)move comments that are misplaced or no longer relevant.
17761 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17763 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17860 * eval.c (struct backtrace): Simplify and port the data structure.
17861 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17862 signed bit field, as this assumption is not portable and it makes
17863 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17864 "char debug_on_exit : 1" as this is not portable either; instead,
17865 use the portable "unsigned int debug_on_exit : 1". Remove unused
17866 member evalargs. Remove obsolete comments about cc bombing out.

17940 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17941 and use min_width/height from frames size_hint to set
17942 min_width/height (Bug#8919).

18053 (read_integer): Radix is now EMACS_INT, not int,
18054 to improve quality of diagnostics for out-of-range radices.
18055 Calculate buffer size correctly for out-of-range radices.
18056 (read1): Check for integer overflow in radices, and in
18057 read-circle numbers.
18058 (read_escape): Avoid int overflow.
18059 (Fload, openp, read_buffer_size, read1)
18060 (substitute_object_recurse, read_vector, read_list, map_obarray):

18101 on undefined behavior with wrong number of arguments.
18102 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18103 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18104 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18105 since we're not interested in debugging glyphs with old libraries.
18106 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18107 GCC 4.6.0's static checking.

18149 (x_session_initialize): Do not assume string length fits in int.
18151 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

18178 * lread.c (intern, intern_c_string):
18179 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

18197 Don't assume pid_t and time_t fit in unsigned long.
18198 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18199 (current_lock_owner): Prefer signed type for sizes.
18200 Use memcpy, not strncpy, where memcpy is what is really wanted.
18201 Don't assume (via atoi) that time_t and pid_t fit in int.
18202 Check for time_t and/or pid_t out of range, e.g., via a network share.
18203 Don't alloca where an auto var works fine.

18216 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18218 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18219 We prefer signed integers, even for size calculations.
18221 * emacs.c: Don't assume string length fits in 'int'.
18222 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18223 (main): Don't invoke strlen when not needed.
18225 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18226 (XD_DEBUG_MESSAGE): Don't waste a byte.
18228 * callproc.c (getenv_internal_1, getenv_internal)
18229 (Fgetenv_internal):
18230 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18232 * lread.c (invalid_syntax): Omit length argument.
18233 All uses changed. This doesn't fix a bug, but it simplifies the
18234 code away from its former Hollerith-constant appearance, and it's
18235 one less 'int' to worry about when looking at integer-overflow issues.
18236 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18238 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18239 This didn't break anything, but it didn't help either.
18240 It's confusing to put a bogus integer in a place where the actual
18241 value does not matter.
18242 (LIST_END_P): Remove unused macro and its bogus comment.
18243 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18245 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18246 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18248 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18249 We prefer signed types, and the value cannot exceed the EMACS_INT
18250 range anyway (because otherwise the length would not be representable).
18251 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18252 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18253 This avoids a GCC warning when WIDE_EMACS_INT.
18255 * indent.c (sane_tab_width): New function.
18256 (current_column, scan_for_column, Findent_to, position_indentation)
18257 (compute_motion): Use it. This is just for clarity.
18258 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18260 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18262 * lisp.h (lint_assume): New macro.
18263 * composite.c (composition_gstring_put_cache):
18264 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18266 * editfns.c, insdel.c:
18267 Omit unnecessary forward decls, to simplify future changes.
18269 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18271 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18273 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18274 Use much-faster test for byte-length change.
18275 Don't assume string byte-length fits in 'int'.
18276 Check that character arg fits in 'int'.
18277 (mapcar1): Declare byte as byte, for clarity.
18279 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18281 * fns.c (concat): Catch string overflow earlier.
18282 Do not rely on integer wraparound.
18284 * dispextern.h (struct it.overlay_strings_charpos)
18285 (struct it.selective): Now EMACS_INT, not int.
18286 * xdisp.c (forward_to_next_line_start)
18287 (back_to_previous_visible_line_start)
18288 (reseat_at_next_visible_line_start, next_element_from_buffer):
18289 Don't arbitrarily truncate the value of 'selective' to int.
18291 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18293 * composite.c: Don't truncate sizes to 'int'.
18294 (composition_gstring_p, composition_reseat_it)
18295 (composition_adjust_point): Use EMACS_INT, not int.
18296 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18297 not EMACS_UINT, for indexes.
18299 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18301 * buffer.c: Include <verify.h>.
18302 (struct sortvec.priority, struct sortstr.priority):
18303 Now EMACS_INT, not int.
18304 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18305 (struct sortstr.size, record_overlay_string)
18306 (struct sortstrlist.size, struct sortlist.used):
18307 Don't truncate size to int.
18308 (record_overlay_string): Check for size-calculation overflow.
18309 (init_buffer_once): Check at compile-time, not run-time.
18311 2011-06-22 Jim Meyering <meyering@redhat.com>
18313 Don't leak an XBM-image-sized buffer
18314 * image.c (xbm_load): Free the image buffer after using it.
18316 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18319 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18320 that Sun C diagnosed.
18321 * fns.c (secure_hash): Fix pointer signedness issue.
18322 * intervals.c (static_offset_intervals): New function.
18323 (offset_intervals): Use it.
18325 2011-06-21 Leo Liu <sdl.web@gmail.com>
18328 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18331 * fns.c (secure_hash): Rename from crypto_hash_function and change
18332 the first arg to accept symbols.
18333 (Fsecure_hash): New primitive.
18334 (syms_of_fns): New symbols.
18336 2011-06-20 Deniz Dogan <deniz@dogan.se>
18338 * process.c (Fset_process_buffer): Clarify return value in
18341 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18343 * dispnew.c (add_window_display_history): Use BVAR.
18345 * xdisp.c (debug_method_add): Use BVAR.
18346 (check_window_end, dump_glyph_matrix, dump_glyph)
18347 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18349 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18352 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18353 check till after the cache is created in init_frame_faces.
18355 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18357 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18359 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18361 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18362 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18363 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18365 Improve buffer-overflow checking (Bug#8873).
18366 * fileio.c (Finsert_file_contents):
18367 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18368 Remove the old (too-loose) buffer overflow checks.
18369 They weren't needed, since make_gap checks for buffer overflow.
18370 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18371 The old code merely checked for Emacs fixnum overflow, and relied
18372 on undefined (wraparound) behavior. The new code avoids undefined
18373 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18375 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18376 Tune. Don't use wider integers than needed. Don't use alloca.
18377 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18379 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18381 * insdel.c, lisp.h (buffer_overflow): New function.
18382 (insert_from_buffer_1, replace_range, replace_range_2):
18383 * insdel.c (make_gap_larger):
18384 * editfns.c (Finsert_char):
18385 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18387 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18389 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18391 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18393 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18394 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18396 * fileio.c: Don't assume EMACS_INT fits in off_t.
18397 (emacs_lseek): New static function.
18398 (Finsert_file_contents, Fwrite_region): Use it.
18399 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18401 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18403 * fns.c: Don't overflow int when computing a list length.
18404 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18405 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18406 truncation on 64-bit hosts. Check for QUIT every
18407 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18408 faster and is responsive enough.
18409 (Flength): Report an error instead of overflowing an integer.
18410 (Fsafe_length): Return a float if the value is not representable
18411 as a fixnum. This shouldn't happen except in contrived situations.
18412 (Fnthcdr, Fsort): Don't assume list length fits in int.
18413 (Fcopy_sequence): Don't assume vector length fits in int.
18415 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18416 (header_size, word_size): New constants.
18417 (allocate_vectorlike): Don't check size overflow here.
18418 (allocate_vector): Check it here instead, since this is the only
18419 caller of allocate_vectorlike that could cause overflow.
18420 Check that the new vector's length is representable as a fixnum.
18422 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18423 The previous code was bogus. For example, next_almost_prime (32)
18424 returned 39, which is undesirable as it is a multiple of 3; and
18425 next_almost_prime (24) returned 25, which is a multiple of 5 so
18426 why was the code bothering to check for multiples of 7?
18428 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18430 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18432 Variadic C functions now count arguments with ptrdiff_t.
18433 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18434 Back then I didn't know that the Emacs coding style prefers signed int.
18435 Also, in the meantime I found a few more instances where arguments
18436 were being counted with int, which may truncate counts on 64-bit
18437 machines, or EMACS_INT, which may be unnecessarily wide.
18438 * lisp.h (struct Lisp_Subr.function.aMANY)
18439 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18440 Arg counts are now ptrdiff_t, not size_t.
18441 All variadic functions and their callers changed accordingly.
18442 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18443 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18444 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18445 * callint.c (Fcall_interactively): Check arg count for overflow,
18446 to avoid potential buffer overrun. Use signed char, not 'int',
18447 for 'varies' array, so that we needn't bother to check its size
18448 calculation for overflow.
18449 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18450 * eval.c (apply_lambda):
18451 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18452 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18453 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18455 * callint.c (Fcall_interactively): Don't use index var as event count.
18457 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18458 * mem-limits.h (SIZE): Remove; no longer used.
18460 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18462 Remove unnecessary casts.
18463 * xterm.c (x_term_init):
18464 * xfns.c (x_set_border_pixel):
18465 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18466 These aren't needed now that we assume ANSI C.
18468 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18469 It's more likely to cause problems (due to unsigned overflow)
18472 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18474 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18476 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18478 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18480 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18482 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18484 GLYPH_CODE_FACE returns EMACS_INT, not int.
18485 * dispextern.h (merge_faces):
18486 * xfaces.c (merge_faces):
18487 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18488 Don't assume EMACS_INT fits in int.
18490 * character.h (CHAR_VALID_P): Remove unused parameter.
18491 * fontset.c, lisp.h, xdisp.c: All uses changed.
18493 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18495 * fns.c (concat): Minor tuning based on overflow analysis.
18496 This doesn't fix any bugs. Use int to hold character, instead
18497 of constantly refetching from Emacs object. Use XFASTINT, not
18498 XINT, for value known to be a character. Don't bother comparing
18499 a single byte to 0400, as it's always less.
18501 * floatfns.c (Fexpt):
18502 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18504 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18507 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18509 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18510 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18511 incorrectly succeed when S was a string, because 4294967386 was
18512 truncated before it was used.
18514 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18515 Otherwise, an out-of-range integer could cause undefined behavior
18518 * composite.c: Use int, not EMACS_INT, for characters.
18519 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18520 EMACS_INT, for values that are known to be in character range.
18521 This doesn't fix any bugs but is the usual style inside Emacs and
18522 may generate better code on 32-bit machines.
18524 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18525 This is for reasons similar to the recent CHAR_STRING fix.
18526 * charset.c (Fencode_char): Check that character arg is actually
18527 a character. Pass an int to ENCODE_CHAR.
18528 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18529 wider than 'int', as a compile-time check to prevent future regressions
18532 * character.c (char_string): Remove unnecessary casts.
18534 Make sure a 64-bit char is never passed to CHAR_STRING.
18535 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18536 by silently ignoring the top 32 bits, allowing some values
18537 that were far too large to be valid characters.
18538 * character.h: Include <verify.h>.
18539 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18540 arguments are no wider than unsigned, as a compile-time check
18541 to prevent future regressions in this area.
18543 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18544 (Fsubst_char_in_region):
18546 * xdisp.c (decode_mode_spec_coding):
18547 Adjust to CHAR_STRING's new requirement.
18548 * editfns.c (Finsert_char, Fsubst_char_in_region):
18549 * fns.c (concat): Check that character args are actually
18550 characters. Without this test, these functions did the wrong
18551 thing with wildly out-of-range values on 64-bit hosts.
18553 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18554 These casts should not be needed on 32-bit hosts, either.
18555 * keyboard.c (read_char):
18556 * lread.c (Fload): Remove casts to unsigned.
18558 * lisp.h (UNSIGNED_CMP): New macro.
18559 This fixes comparison bugs on 64-bit hosts.
18560 (ASCII_CHAR_P): Use it.
18561 * casefiddle.c (casify_object):
18562 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18563 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18564 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18565 * dispextern.h (FACE_FROM_ID):
18566 * keyboard.c (read_char): Use UNSIGNED_CMP.
18568 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18569 not to EMACS_INT, to avoid GCC warning.
18571 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18573 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18574 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18575 isn't needed on 32-bit machines.
18577 * buffer.c (Fgenerate_new_buffer_name):
18578 Use EMACS_INT for count, not int.
18579 (advance_to_char_boundary): Return EMACS_INT, not int.
18581 * data.c (Qcompiled_function): Now static.
18583 * window.c (window_body_lines): Now static.
18585 * image.c (gif_load): Rename local to avoid shadowing.
18587 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18588 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18589 * alloc.c (make_save_value): Integer argument is now of type
18590 ptrdiff_t, not int.
18591 (mark_object): Use ptrdiff_t, not int.
18592 * lisp.h (pD): New macro.
18593 * print.c (print_object): Use it.
18595 * alloc.c: Use EMACS_INT, not int, to count objects.
18596 (total_conses, total_markers, total_symbols, total_vector_size)
18597 (total_free_conses, total_free_markers, total_free_symbols)
18598 (total_free_floats, total_floats, total_free_intervals)
18599 (total_intervals, total_strings, total_free_strings):
18600 Now EMACS_INT, not int. All uses changed.
18601 (Fgarbage_collect): Compute overall total using a double, so that
18602 integer overflow is less likely to be a problem. Check for overflow
18603 when converting back to an integer.
18604 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18605 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18606 These were 'int' variables that could overflow on 64-bit hosts;
18607 they were never used, so remove them instead of repairing them.
18608 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18609 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18610 Previously, this ceilinged at INT_MAX, but that doesn't work on
18612 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18614 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18615 (allocate_vectorlike): Check for ptrdiff_t overflow.
18616 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18617 when a (possibly-narrower) signed value would do just as well.
18618 We prefer using signed arithmetic, to avoid comparison confusion.
18620 * alloc.c: Catch some string size overflows that we were missing.
18621 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18622 for convenience in STRING_BYTES_MAX.
18623 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18624 The definition here is exact; the one in lisp.h was approximate.
18625 (allocate_string_data): Check for string overflow. This catches
18626 some instances we weren't catching before. Also, it catches
18627 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18628 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18629 and ptrdiff_t and EMACS_INT are both 64 bits.
18631 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18632 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18633 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18635 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18637 * alloc.c (Fmake_string): Check for out-of-range init.
18639 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18641 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18643 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18645 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18646 xg_get_default_scrollbar_width.
18648 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18649 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18650 (style_changed_cb): Call update_theme_scrollbar_width and call
18651 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18652 all frames (Bug#8505).
18653 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18654 Call gtk_window_set_resizable if HAVE_GTK3.

19103 Fframe_first_window and Fset_frame_selected_window to window.h.
19105 * window.h: Move EXFUNS for Fframe_root_window,
19106 Fframe_first_window and Fset_frame_selected_window here from

19110 (Fframe_root_window, Fframe_selected_window)
19111 (Fset_frame_selected_window): Move to window.c.
19112 (Factive_minibuffer_window): Move to minibuf.c.
19113 (Fother_visible_frames_p): New function.

19129 (Fwindow_minibuffer_p): Move up in code and simplify.
19130 (Fset_frame_selected_window): Move here from frame.c.
19132 (Fselected_window, select_window, Fselect_window): Move up in
19133 code. Minor doc-string fixes.
19135 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
19137 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
19138 Do not assume that spare memory exists; that assumption is valid
19139 only if SYSTEM_MALLOC.
19140 (LARGE_REQUEST): New macro, so that the issue of large requests
19141 is separated from the issue of spare memory.
19143 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
19145 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

19171 New error handlers.
19172 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
19173 Obey Vx_select_enable_clipboard_manager. Catch errors in
19174 x_clipboard_manager_save (Bug#8779).
19175 (Vx_select_enable_clipboard_manager): New variable.
19176 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19178 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19180 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19182 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19184 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
19185 in the current matrix if keep_current_p is non-zero.

19189 * bidi.c (bidi_level_of_next_char): Fix last change.
19191 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19193 Support bidi reordering of text covered by display properties.
19195 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19196 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19197 (bidi_cache_search, bidi_cache_iterator_state)
19198 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19199 (bidi_level_of_next_char, bidi_move_to_visually_next):
19200 Support character positions inside a run of characters covered by a
19202 (bidi_paragraph_init, bidi_resolve_explicit_1)
19203 (bidi_level_of_next_char): Call bidi_fetch_char and
19204 bidi_fetch_char_advance instead of FETCH_CHAR and
19205 FETCH_CHAR_ADVANCE.
19206 (bidi_init_it): Initialize new members.
19207 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19209 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19210 instead of using explicit *_CHAR codes.
19211 (bidi_resolve_explicit, bidi_resolve_weak):
19212 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19213 bidirectional text is supported only in multibyte buffers.
19214 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19215 it to initialize the frame_window_p member of struct bidi_it.
19216 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19217 (bidi_resolve_explicit, bidi_resolve_weak)

19219 bidi_it->nchars is non-positive.
19220 (bidi_level_of_next_char): Don't try to lookup the cache for the
19221 next/previous character if nothing is cached there yet, or if we
19222 were just reseat()'ed to a new position.
19224 * xdisp.c (set_cursor_from_row): Set start and stop points
19225 according to the row's direction when priming the loop that looks
19226 for the glyph on which to display cursor.
19227 (single_display_spec_intangible_p): Function deleted.
19228 (display_prop_intangible_p): Reimplement to call
19229 handle_display_spec instead of single_display_spec_intangible_p.
19230 Accept 3 additional arguments needed by handle_display_spec.
19231 This fixes incorrect cursor motion across display property with complex
19232 values: lists, `(when COND...)' forms, etc.
19233 (single_display_spec_string_p): Support property values that are
19234 lists with the argument STRING its top-level element.
19235 (display_prop_string_p): Fix the condition for processing a
19236 property that is a list to be consistent with handle_display_spec.
19237 (handle_display_spec): New function, refactored from the
19238 last portion of handle_display_prop.
19239 (compute_display_string_pos): Accept additional argument
19240 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19241 value of a `display' property is a "replacing spec".
19242 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19243 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19244 the display property, but just return a value indicating whether
19245 the display property will replace the characters it covers.
19246 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19247 frame_window_p members of struct bidi_it.
19248 (compute_display_string_pos, compute_display_string_end):
19250 (push_it): Accept second argument POSITION, where pop_it should
19251 jump to continue iteration.
19252 (reseat_1): Initialize bidi_it.disp_pos.
19254 * keyboard.c (adjust_point_for_property): Adjust the call to
19255 display_prop_intangible_p to its new signature.
19257 * dispextern.h (struct bidi_it): New member frame_window_p.
19258 (bidi_init_it): Update prototypes.
19259 (display_prop_intangible_p): Update prototype.
19260 (compute_display_string_pos, compute_display_string_end):
19261 Declare prototypes.
19262 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19265 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19267 Malloc failure behavior now depends on size of allocation.
19268 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19269 * lisp.h: Change signatures accordingly.
19270 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19271 All callers changed. (Bug#8762)
19273 * gnutls.c: Use Emacs's memory allocators.
19274 Without this change, the gnutls library would invoke malloc etc.
19275 directly, which causes problems on non-SYNC_INPUT hosts, and which
19276 runs afoul of improving memory_full behavior. (Bug#8761)
19277 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19278 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19279 xfree instead of the default malloc, realloc, free.
19280 (Fgnutls_boot): No need to check for memory allocation failure,
19281 since xmalloc does that for us.
19283 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19284 * category.c (hash_get_category_set):
19285 * ccl.c (ccl_driver):
19286 * charset.c (Fdefine_charset_internal):
19287 * charset.h (struct charset.hash_index):

19297 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19298 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19299 * image.c (make_image, search_image_cache, lookup_image)
19300 (xpm_put_color_table_h):
19301 * lisp.h (struct Lisp_Hash_Table):
19302 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19303 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19304 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19305 * alloc.c (allocate_vectorlike):
19306 Check for overflow in vector size calculations.
19307 * ccl.c (ccl_driver):
19308 Check for overflow when converting EMACS_INT to int.
19309 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19310 need to be updated by these changes.
19311 * fns.c (make_hash_table, maybe_resize_hash_table):
19312 Check for integer overflow with large hash tables.
19313 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19314 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19315 (SXHASH_REDUCE): New macro.
19316 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19317 Use it instead of discarding useful hash info with large hash values.
19318 (sxhash_float): New function.
19319 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19320 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19321 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19322 Rewrite to use FIXNUM_BITS, as this simplifies things.
19323 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19324 Adjust signatures to match updated version of code.
19325 (consing_since_gc): Now EMACS_INT, since a single hash table can
19326 use more than INT_MAX bytes.
19328 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19330 Make it possible to build with GCC-4.6+ -O2 -flto.
19332 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19334 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19336 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19337 Call minibuffer-inactive-mode.
19339 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19341 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19342 Update dependencies.
19344 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19346 * data.c (init_data): Remove code for UTS, this system is not
19349 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19351 Don't force ./temacs to start in terminal mode.
19353 * frame.c (make_initial_frame): Initialize faces in all cases, not
19354 only when CANNOT_DUMP is defined.
19355 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19357 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19359 * dispnew.c (add_window_display_history): Use const for the string
19360 pointer. Remove declaration, not needed.
19362 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19364 Use 'inline', not 'INLINE'.
19365 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19366 * alloc.c, fontset.c (INLINE): Remove.
19367 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19368 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19369 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19370 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19371 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19373 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19375 Make it possible to run ./temacs.
19377 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19378 syms_of_callproc does the same thing. Remove test for
19379 "initialized", do it in the caller.
19380 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19382 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19384 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19385 (read_minibuf): Use get_minibuffer.
19386 (syms_of_minibuf): Use DEFSYM.
19387 (Qmetadata): New var.
19388 * data.c (Qbuffer): Don't make it static.
19389 (syms_of_data): Use DEFSYM.
19391 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19393 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19394 (CCL_CODE_MIN): New macro.
19396 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19398 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19400 * eval.c (Qdebug): Now static.
19401 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19402 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19403 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19405 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19407 * image.c: Various fixes to ImageMagick code comments.
19408 (Fimagemagick_types): Doc fix.
19410 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19412 Minor fixes prompted by GCC 4.6.0 warnings.
19414 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19416 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19417 (x_clipboard_manager_save_all): Move extern decl to ...
19418 * xterm.h: ... here, so that it can be checked for consistency.
19420 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19422 * xselect.c (x_clipboard_manager_save_frame)
19423 (x_clipboard_manager_save_all): New functions.
19424 (Fx_clipboard_manager_save): Lisp function deleted.
19426 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19427 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19429 * xterm.h: Update prototype.
19431 2011-05-28 William Xu <william.xwl@gmail.com>
19433 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19434 exiting (Bug#8239).
19436 2011-05-28 Jim Meyering <meyering@redhat.com>
19438 Avoid a sign-extension bug in crypto_hash_function.
19439 * fns.c (to_uchar): Define.
19440 (crypto_hash_function): Use it to convert some newly-signed
19441 variables to unsigned, to avoid sign-extension bugs. For example,
19442 without this change, (md5 "truc") would evaluate to
19443 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19444 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19445 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19447 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19449 Integer overflow fixes.
19451 * dbusbind.c: Serial number integer overflow fixes.
19452 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19453 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19454 to hold a serial number that is too large for a fixnum.
19455 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19456 Check for serial numbers out of range. Decode any serial number
19457 that was so large that it became a float. (Bug#8722)
19459 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19460 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19461 Use XFASTINT rather than XUINT when numbers are nonnegative.
19462 (xd_append_arg, Fdbus_method_return_internal):
19463 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19464 arguments, check that Lisp number is nonnegative, rather than
19465 silently wrapping negative numbers around. (Bug#8722)
19466 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19469 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19471 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19473 ccl: Add integer overflow checks.
19474 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19475 (IN_INT_RANGE): New macros.
19476 (ccl_driver): Use them to check for integer overflow when
19477 decoding a CCL program. Many of the new checks are whether XINT (x)
19478 fits in int; it doesn't always, on 64-bit hosts. The new version
19479 doesn't catch all possible integer overflows, but it's an
19480 improvement. (Bug#8719)
19482 * alloc.c (make_event_array): Use XINT, not XUINT.
19483 There's no need for unsigned here.
19485 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19486 This follows up to the 2011-05-06 change that substituted uintptr_t
19487 for EMACS_INT. This case wasn't caught back then.
19489 Rework Fformat to avoid integer overflow issues.
19490 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19491 now (part of C89). Include <verify.h>.
19492 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19493 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19494 (Fformat): Avoid the prepass trying to compute sizes; it was only
19495 approximate and thus did not catch overflow reliably. Instead, walk
19496 through the format just once, formatting and computing sizes as we go,
19497 checking for integer overflow at every step, and allocating a larger
19498 buffer as needed. Keep track separately whether the format is
19499 multibyte. Keep only the most-recently calculated precision, rather
19500 than them all. Record whether each argument has been converted to
19501 string. Use EMACS_INT, not int, for byte and char and arg counts.
19502 Support field widths and precisions larger than INT_MAX. Avoid
19503 sprintf's undefined behavior with conversion specifications such as %#d
19504 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19505 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19506 formatting out-of-range floating point numbers with int
19507 formats. (Bug#8668)
19509 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19511 * data.c: Avoid integer truncation in expressions involving floats.
19512 * data.c: Include <intprops.h>.
19513 (arith_driver): When there's an integer overflow in an expression
19514 involving floating point, convert the integers to floating point
19515 so that the resulting value does not suffer from catastrophic
19516 integer truncation. For example, on a 64-bit host (* 4
19517 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19518 Do not rely on undefined behavior after integer overflow.
19520 merge count_size_as_multibyte, parse_str_to_multibyte
19521 * character.c, character.h (count_size_as_multibyte):
19522 Rename from parse_str_to_multibyte; all uses changed.
19523 Check for integer overflow.
19524 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19525 since it's now a duplicate of the other. This is more of
19526 a character than a buffer op, so better that it's in character.c.
19527 * fns.c, print.c: Adjust to above changes.
19529 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19531 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19533 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19535 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19536 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19537 (x_clipboard_manager_save): Now static.
19538 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19540 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19541 (crypto_hash_function): Now static.
19542 Fix pointer signedness problems. Avoid unnecessary initializations.
19544 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19546 * termhooks.h (Vselection_alist): Make it terminal-local.
19548 * terminal.c (create_terminal): Initialize it.
19550 * xselect.c: Support for clipboard managers.
19551 (Vselection_alist): Move to termhooks.h as terminal-local var.
19552 (LOCAL_SELECTION): New macro.
19553 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19554 (symbol_to_x_atom): Remove gratuitous arg.
19555 (x_handle_selection_request, lisp_data_to_selection_data)
19556 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19557 (x_own_selection, x_get_local_selection, x_convert_selection):
19558 New arg, specifying work frame. Use terminal-local Vselection_alist.
19559 (some_frame_on_display): Delete unused function.
19560 (Fx_own_selection_internal, Fx_get_selection_internal)
19561 (Fx_disown_selection_internal, Fx_selection_owner_p)
19562 (Fx_selection_exists_p): New optional frame arg.
19563 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19564 (x_handle_selection_clear): Don't treat other terminals with the
19565 same keyboard specially. Use the terminal-local Vselection_alist.
19566 (x_clear_frame_selections): Use Frun_hook_with_args.
19568 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19570 * xterm.h: Add support for those atoms.
19572 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19574 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19575 (converted_selections, conversion_fail_tag): New global variables.
19576 (x_selection_request_lisp_error): Free the above.
19577 (x_get_local_selection): Remove unnecessary code.
19578 (x_reply_selection_request): Args changed; handle arbitrary array
19579 of converted selections stored in converted_selections.
19580 Separate the XChangeProperty and SelectionNotify steps.
19581 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19582 (x_convert_selection): New function.
19583 (x_handle_selection_event): Simplify.
19584 (x_get_foreign_selection): Don't ignore incoming requests while
19585 waiting for an answer; this will fail when we implement
19586 SAVE_TARGETS, and seems unnecessary anyway.
19587 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19588 (Vx_sent_selection_functions): Doc fix.
19590 2011-05-26 Leo Liu <sdl.web@gmail.com>
19592 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19594 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19596 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19598 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19599 for fringe update if it has periodic bitmap.
19600 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19601 and fringe_bitmap_periodic_p.
19603 * fringe.c (get_fringe_bitmap_data): New function.
19604 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19605 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19606 row. Mark glyph row for fringe update if periodicity changed.
19608 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19609 for fringe update unless it has periodic bitmap.
19611 2011-05-25 Kenichi Handa <handa@m17n.org>
19613 * xdisp.c (get_next_display_element): Set correct it->face_id for
19614 a static composition.
19616 2011-05-24 Leo Liu <sdl.web@gmail.com>
19619 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19621 * fns.c (crypto_hash_function, Fsha1): New function.
19622 (Fmd5): Use crypto_hash_function.
19623 (syms_of_fns): Add Ssha1.
19625 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19627 * gnutls.c: Remove unused macros.
19628 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19629 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19630 Remove macros that are defined and never used.
19631 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19633 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19635 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19636 (Fx_get_selection_internal): Minor cleanup.
19637 (Fx_own_selection_internal): Rename arguments for consistency with
19640 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19642 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19644 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19646 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19648 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19650 * dispnew.c (scrolling_window): Don't exclude the case that the
19651 last enabled row in the desired matrix touches the bottom boundary.
19653 2011-05-21 Glenn Morris <rgm@gnu.org>
19655 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19656 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19657 and add some more files.
19659 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19661 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19662 report_file_error introduced by the change from 2011-05-07.
19664 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19666 * systime.h (Time): Define only if emacs is defined.
19667 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19668 where the include path doesn't have X11/X.h by default. See
19669 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19671 2011-05-20 Kenichi Handa <handa@m17n.org>
19673 * composite.c (find_automatic_composition): Fix previous change.
19675 2011-05-20 Glenn Morris <rgm@gnu.org>
19677 * lisp.mk: New file, split from Makefile.in.
19678 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19679 (shortlisp): Remove.
19680 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19682 2011-05-19 Glenn Morris <rgm@gnu.org>
19684 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19685 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19686 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19687 (lisp): Set the order to that of loadup.el.
19688 (shortlisp): Make it a copy of $lisp.
19689 (SOME_MACHINE_LISP): Remove.
19690 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19691 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19693 2011-05-18 Kenichi Handa <handa@m17n.org>
19695 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19696 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19697 (find_automatic_composition): Mostly rewrite for efficiency.
19699 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19701 * makefile.w32-in: Update dependencies.
19703 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19705 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19706 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19708 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19710 Fix some integer overflow issues, such as string length overflow.
19712 * insdel.c (count_size_as_multibyte): Check for string overflow.
19714 * character.c (lisp_string_width): Check for string overflow.
19715 Use EMACS_INT, not int, for string indexes and lengths; in
19716 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19717 the resulting string length overflows an EMACS_INT; instead,
19718 report a string overflow if no precision given. When checking for
19719 precision exhaustion, use a check that cannot possibly have
19720 integer overflow. (Bug#8675)
19721 * character.h (lisp_string_width): Adjust to new signature.
19723 * alloc.c (string_overflow): New function.
19724 (Fmake_string): Use it. This doesn't change behavior, but saves
19725 a few bytes and will simplify future changes.
19726 * character.c (string_escape_byte8): Likewise.
19727 * lisp.h (string_overflow): New decl.
19729 Fixups, following up to the user-interface timestamp change.
19730 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19731 for UI timestamps, instead of unsigned long.
19732 * msdos.c (mouse_get_pos): Likewise.
19733 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19734 * w32gui.h (Time): Define by including "systime.h" rather than by
19735 declaring it ourselves. (Bug#8664)
19737 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19738 * image.c (clear_image_cache): Likewise.
19740 * term.c (term_mouse_position): Don't assume time_t wraparound.
19742 Be more systematic about user-interface timestamps.
19743 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19744 and sometimes 'EMACS_UINT', to represent these timestamps.
19745 This change causes it to use 'Time' uniformly, as that's what X uses.
19746 This makes the code easier to follow, and makes it easier to catch
19747 integer overflow bugs such as Bug#8664.
19748 * frame.c (Fmouse_position, Fmouse_pixel_position):
19749 Use Time, not unsigned long, for user-interface timestamps.
19750 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19751 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19752 * keyboard.h (last_event_timestamp): Likewise.
19753 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19754 * menu.h (xmenu_show): Likewise.
19755 * term.c (term_mouse_position): Likewise.
19756 * termhooks.h (struct input_event.timestamp): Likewise.
19757 (struct terminal.mouse_position_hook): Likewise.
19758 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19759 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19760 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19761 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19762 what it was before.
19763 * menu.h, termhooks.h: Include "systime.h", for Time.
19765 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19766 Don't assume that the difference between two unsigned long values
19767 can fit into an integer. At this point, we know button_down_time
19768 <= event->timestamp, so the difference must be nonnegative, so
19769 there's no need to cast the result if double-click-time is
19770 nonnegative, as it should be; check that it's nonnegative, just in
19771 case. This bug is triggered when events are more than 2**31 ms
19772 apart (about 25 days). (Bug#8664)
19774 * xselect.c (last_event_timestamp): Remove duplicate decl.
19775 (x_own_selection): Remove needless cast to unsigned long.
19777 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19778 that always fit in int. Use a sentinel instead of a counter, to
19779 avoid a temp and to allay GCC's concerns about possible int overflow.
19780 * frame.h (struct frame): Use int for menu_bar_items_used
19781 instead of EMACS_INT, since it always fits in int.
19783 * menu.c (grow_menu_items): Check for int overflow.
19785 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19787 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19788 Before, the code was not consistent. These values cannot exceed
19789 2**31 - 1 so there's no need to make them unsigned.
19790 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19791 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19792 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19794 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19796 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19797 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19798 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19799 presumably because the widths might not match.
19801 * window.c (size_window): Avoid needless test at loop start.
19803 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19805 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19807 2011-05-12 Drew Adams <drew.adams@oracle.com>
19809 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19811 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19813 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19814 `width' to `bar_area_x' and `bar_area_width', respectively.
19815 (x_scroll_run): Take account of fringe background extension.
19817 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19818 Rename local vars `left' and `width' to `bar_area_x' and
19819 `bar_area_width', respectively.
19820 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19821 background extension.
19823 2011-05-10 Jim Meyering <meyering@redhat.com>
19825 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19827 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19829 * image.c (Finit_image_library): Return t for built-in image types,
19830 like pbm and xbm. (Bug#8640)
19832 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19834 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19836 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19838 * w32console.c (Fset_screen_color): Doc fix.
19839 (Fget_screen_color): New function.
19840 (syms_of_ntterm): Defsubr it.
19842 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19843 unlink the temporary file if Fcall_process didn't create it in the
19845 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19846 child process will be redirected to a file specified with `:file'.
19847 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19848 cue to call_process_cleanup not to close that handle.
19850 2011-05-07 Ben Key <bkey76@gmail.com>
19852 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19853 one of two shell specific rules, either bootstrap-temacs-CMD or
19854 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19855 to the previous implementation of the bootstrap-temacs rule.
19856 The bootstrap-temacs-CMD rule is similar to the previous
19857 implementation of the bootstrap-temacs rule except that it
19858 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19861 These changes, along with some changes to nt/configure.bat,
19862 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19863 earlier fix to add support for --cflags and --ldflags options
19864 that include quotes so that it works whether make uses cmd or
19867 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19869 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19870 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19872 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19873 a string. Handle both cases.
19874 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19875 (Fdbus_register_method): Use Qinvalid_function.
19877 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19879 * makefile.w32-in: Update dependencies.
19880 (LISP_H): Add inttypes.h and stdin.h.
19881 (PROCESS_H): Add unistd.h.
19883 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19885 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19886 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19888 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19890 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19892 * term.c (vfatal): Remove stray call to va_end.
19893 It's not needed and the C Standard doesn't allow it here anyway.
19895 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19896 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19898 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19901 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19903 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19905 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19907 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19909 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19911 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19912 * charset.c (Fdefine_charset_internal): Don't initialize
19913 charset.code_space[15]. The value was garbage, on hosts with
19914 32-bit int (Bug#8600).
19916 * lread.c (read_integer): Be more consistent with string-to-number.
19917 Use string_to_number to do the actual conversion; this avoids
19918 rounding errors and fixes some other screwups. Without this fix,
19919 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19920 (digit_to_number): Move earlier, for benefit of read_integer.
19921 Return -1 if the digit is out of range for the base, -2 if it is
19922 not a digit in any supported base. (Bug#8602)
19924 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19926 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19927 to match comment at start of function. This also removes a
19928 GCC warning about overflow in a 32+64-bit port.
19930 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19932 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19933 Reported by Stefan Monnier in
19934 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19935 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19936 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19938 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19939 (EMACS_UINTPTR): Likewise, with uintptr_t.
19941 * lisp.h: Prefer 64-bit EMACS_INT if available.
19942 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19943 on 32-bit hosts that have 64-bit int, so that they can access
19945 However, temporarily disable this change unless the temporary
19946 symbol WIDE_EMACS_INT is defined.
19948 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19950 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19951 This removes an assumption that EMACS_INT and long are the same
19952 width as pointers. The assumption is true for Emacs porting targets
19953 now, but we want to make other targets possible.
19954 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19955 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19956 In the rest of the code, change types of integers that hold casted
19957 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19958 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19959 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19960 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19961 No need to cast type when ORing.
19962 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19963 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19964 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19965 assume EMACS_INT is the same width as char *.
19966 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19967 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19968 Remove no-longer-needed casts.
19969 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19970 (xg_tool_bar_help_callback, xg_make_tool_item):
19971 Use EMACS_INTPTR to hold an integer
19972 that will be cast to void *; this can avoid a GCC warning
19973 if EMACS_INT is not the same width as void *.
19974 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19975 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19976 (current_message_1, set_message_1):
19977 Use a local to convert to proper width without a cast.
19978 * xmenu.c (dialog_selection_callback): Likewise.
19980 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19981 Also, don't assume VALBITS / RAND_BITS is less than 5,
19982 and don't rely on undefined behavior when shifting a 1 left into
19984 * lisp.h (get_random): Change signature to match.
19986 * lread.c (hash_string): Use size_t, not int, for hash computation.
19987 Normally we prefer signed values; but hashing is special, because
19988 it's better to use unsigned division on hash table sizes so that
19989 the remainder is nonnegative. Also, size_t is the natural width
19990 for hashing into memory. The previous code used 'int', which doesn't
19991 retain enough info to hash well into very large tables.
19992 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19994 * dbusbind.c: Don't possibly lose pointer info when converting.
19995 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19996 Use XPNTR rather than XHASH, so that the high-order bits of
19997 the pointer aren't lost when converting through void *.
19999 * eval.c (Fautoload): Don't double-shift a pointer.
20001 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

20035 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20036 Remove unused parameter `fildes'.
20037 * process.c (read_process_output, send_process): Don't pass it.
20039 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20041 Fix previous change: the library cache is defined in w32.c.
20042 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20043 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

20085 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20086 instead of gnutls_record_check_pending.
20088 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20090 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20092 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20093 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20096 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20098 * xterm.c (x_set_frame_alpha): Do not set property on anything

20133 (Fcall_process_region): Ditto.
20135 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20137 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20138 rather than `XVECTOR (FOO)->size'.
20140 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20141 inttypes.h, as a gnulib replacement is used if it not available in
20144 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20146 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20147 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20148 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20150 * coding.c (coding_alloc_by_realloc): Error out if destination
20151 will grow beyond MOST_POSITIVE_FIXNUM.
20152 (decode_coding_emacs_mule): Abort if there isn't enough place in
20153 charbuf for the composition carryover bytes. Reserve an extra

20208 Improve `doprnt' and its usage. (Bug#8545)
20209 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20210 `format_end'. Remove support for %l as a conversion specifier.
20211 Don't use xrealloc. Improve diagnostics when the %l size modifier
20212 is used. Update the commentary.
20214 * eval.c (verror): Simplify calculation of size_t.
20216 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20219 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20221 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20224 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20226 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20227 This makes this file independent of the recent pseudovector change.
20229 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20231 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20233 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20234 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20235 Remove unused local.
20236 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20238 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20239 GCC 4.6.0 optimizes based on type-based alias analysis.
20240 For example, if b is of type struct buffer * and v of type struct
20241 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20242 != &v->size, and therefore "v->size = 1; b->size = 2; return
20243 v->size;" must therefore return 1. This assumption is incorrect
20244 for Emacs, since it type-puns struct Lisp_Vector * with many other
20245 types. To fix this problem, this patch adds a new type struct
20246 vectorlike_header that documents the constraints on layout of vectors
20247 and pseudovectors, and helps optimizing compilers not get fooled
20248 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20249 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20250 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20252 (XSETPVECTYPE): Rewrite in terms of new macro.
20253 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20254 This is a bit clearer, and further avoids the possibility of
20255 undesirable aliasing.
20256 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20257 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20258 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20259 since Lisp_Subr is a special case (no "next" field).
20260 (ASIZE): Now uses header.size rather than size.
20261 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20262 to avoid the hassle of writing XVECTOR (foo)->header.size.
20263 (struct vectorlike_header): New type.
20264 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20265 object, to help avoid aliasing.
20266 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20267 (SUBRP): Likewise, since Lisp_Subr is a special case.
20268 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20269 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20270 (struct Lisp_Hash_Table): Combine first two members into a single
20271 struct vectorlike_header member. All uses of "size" and "next" members
20272 changed to be "header.size" and "header.next".
20273 * buffer.h (struct buffer): Likewise.
20274 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20275 * frame.h (struct frame): Likewise.
20276 * process.h (struct Lisp_Process): Likewise.
20277 * termhooks.h (struct terminal): Likewise.
20278 * window.c (struct save_window_data, struct saved_window): Likewise.
20279 * window.h (struct window): Likewise.
20280 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20281 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20282 * buffer.c (init_buffer_once): Likewise.
20283 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20285 * process.c (Fformat_network_address): Use local var for size,
20288 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20290 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20291 * data.c (atof): Remove decl; no longer used or needed.
20292 (digit_to_number): Move to lread.c.
20293 (Fstring_to_number): Use new string_to_number function, to be
20294 consistent with how the Lisp reader treats infinities and NaNs.
20295 Do not assume that floating-point numbers represent EMACS_INT
20296 without losing information; this is not true on most 64-bit hosts.
20297 Avoid double-rounding errors, by insisting on integers when
20298 parsing non-base-10 numbers, as the documentation specifies.
20299 * lisp.h (string_to_number): New decl, replacing ...
20300 (isfloat_string): Remove.
20301 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20302 (read1): Do not accept +. and -. as integers; this
20303 appears to have been a coding error. Similarly, do not accept
20304 strings like +-1e0 as floating point numbers. Do not report
20305 overflow for integer overflows unless the base is not 10 which
20306 means we have no simple and reliable way to continue.
20307 Break out the floating-point parsing into a new
20308 function string_to_number, so that Fstring_to_number parses
20309 floating point numbers consistently with the Lisp reader.
20310 (digit_to_number): Move here from data.c. Make it static inline.
20311 (E_CHAR, EXP_INT): Remove, replacing with ...
20312 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20313 (string_to_number): New function, replacing isfloat_string.
20314 This function checks for valid syntax and produces the resulting
20315 Lisp float number too. Rework it so that string-to-number
20316 no longer mishandles examples like "1.0e+". Use strtoumax,
20317 so that overflow for non-base-10 numbers is reported only when
20318 there's no portable and simple way to convert to floating point.
20320 * textprop.c (set_text_properties_1): Rewrite for clarity,
20321 and to avoid GCC warning about integer overflow.
20323 * intervals.h (struct interval): Use EMACS_INT for members
20324 where EMACS_UINT might cause problems. See
20325 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20326 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20327 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20329 (offset_intervals): Tell GCC not to worry about length overflow
20330 when negating a negative length.
20332 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20333 (overrun_check_free): Likewise.
20335 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20336 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20339 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20340 (gnutls_make_error): Rename local to avoid shadowing.
20341 (gnutls_emacs_global_deinit): ifdef out; not used.
20342 (Fgnutls_boot): Use const for pointer to readonly storage.
20343 Comment out unused local. Fix pointer signedness problems.
20345 * lread.c (openp): Don't stuff size_t into an 'int'.
20346 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20347 about possible signed overflow.
20349 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20350 (GDK_KEY_g): Don't define if already defined.
20351 (xg_prepare_tooltip): Avoid pointer signedness problem.
20352 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20354 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20355 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20357 * xfns.c (Fx_window_property): Simplify a bit,
20358 to make a bit faster and to avoid GCC 4.6.0 warning.
20359 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20361 * fns.c (internal_equal): Don't assume size_t fits in int.
20363 * alloc.c (compact_small_strings): Tighten assertion a little.
20365 Replace pEd with more-general pI, and fix some printf arg casts.
20366 * lisp.h (pI): New macro, generalizing old pEd macro to other
20367 conversion specifiers. For example, use "...%"pI"d..." rather
20368 than "...%"pEd"...".
20369 (pEd): Remove. All uses replaced with similar uses of pI.
20370 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20371 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20372 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20373 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20374 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20375 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20376 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20378 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20379 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20380 * print.c (safe_debug_print, print_object): Likewise.
20381 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20383 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20384 avoiding the 0 flag, which is not portable.
20385 * process.c (Fmake_network_process): Use pI to avoid cast.
20386 * region-cache.c (pp_cache): Likewise.
20387 * xdisp.c (decode_mode_spec): Likewise.
20388 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined

20392 (x_get_window_property): Don't truncate byte count to an 'int'
20395 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20396 here, since it parses constructs like leading '-' and spaces,
20397 which are not wanted; and it overflows with large numbers.
20398 Instead, simply match F[0-9]+, which is what is wanted anyway.
20400 * alloc.c: Remove unportable assumptions about struct layout.
20401 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20402 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20403 (allocate_vectorlike, make_pure_vector): Use the new macros,
20404 plus offsetof, to remove unportable assumptions about struct layout.
20405 These assumptions hold on all porting targets that I know of, but
20406 they are not guaranteed, they're easy to remove, and removing them
20407 makes further changes easier.
20409 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20410 This doesn't fix a bug but makes the code clearer.
20411 (string_overrun_cookie): Now const. Use initializers that
20412 don't formally overflow signed char, to avoid warnings.
20413 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20414 can cause Emacs to crash when string overrun checking is enabled.
20415 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20416 multiple of sizeof (EMACS_INT); it need not be, if
20417 alignof(EMACS_INT) < sizeof (EMACS_INT).
20418 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

20449 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20450 "cast to pointer from integer of different size".
20452 Improve doprnt and its use in verror. (Bug#8545)
20453 * doprnt.c (doprnt): Document the set of format control sequences
20454 supported by the function. Use SAFE_ALLOCA instead of always
20457 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20458 is one byte too soon. Don't use xrealloc; instead xfree and
20461 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20463 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

20470 docstring. Start callback support.
20471 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20472 unless a fatal error occurred. Call gnutls_alert_send_appropriate

20576 codepoint of an invalid character, to avoid displaying a bogus
20579 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20580 `error', not SYMBOL_NAME itself.
20582 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20583 character arguments to `error'.
20585 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20586 to `error' in error message about FINAL_CHAR argument. Make sure
20587 FINAL_CHAR is a character, and use %c when it is passed as
20588 argument to `error'.
20590 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20592 * s/ms-w32.h (localtime): Redirect to sys_localtime.
20594 * w32.c: Include <time.h>.

20658 * dispextern.h (struct redisplay_interface): Rename param
20659 to avoid shadowing.
20660 * termhooks.h (struct terminal): Likewise.

20777 * nsfont.m: Fixed bugs in ns_get_family and
20778 ns_descriptor_to_entity that were caused by using free to
20779 deallocate memory blocks that were allocated by xmalloc (via
20780 xstrdup). This caused Emacs to crash when compiled with
20781 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20782 --enable-checking=xmallocoverrun). xfree is now used to
20783 deallocate these memory blocks.

20797 (emacs_read, emacs_write): Remove check for negative size, as the
20798 Emacs source code has been audited now.
20799 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
20800 (emacs_read, emacs_write): Use it.
20801 * process.c (send_process): Adjust to the new signatures of
20802 emacs_write and emacs_gnutls_write. Do not attempt to store
20803 a byte offset into an 'int'; it might overflow.

21266 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21267 (overrun_check_free): Protoize.
21269 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21271 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21272 since callers should never pass a negative size.
21273 Change the signature to match that of plain 'read' and 'write'; see
21274 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21275 * lisp.h: Update prototypes of emacs_write and emacs_read.
21277 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21279 * xdisp.c (redisplay_window): Don't try to determine the character
21280 position of the scroll margin if the window start point w->startp
21281 is outside the buffer's accessible region. (Bug#8468)
21283 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21285 Fix write-region and its subroutines for buffers > 2GB.
21286 * fileio.c (a_write, e_write): Modify declaration of arguments and
21287 local variables to support buffers larger than 2GB.
21288 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21290 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21291 argument, local variables, and return value.
21293 * lisp.h: Update prototypes of emacs_write and emacs_read.
21295 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21297 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21299 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21301 Fix more problems found by GCC 4.6.0's static checks.
21303 * xdisp.c (vmessage): Use a better test for character truncation.
21305 * charset.c (load_charset_map): <, not <=, for optimization,
21306 and to avoid potential problems with integer overflow.
21307 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21308 * casetab.c (set_identity, shuffle): Likewise.
21309 * editfns.c (Fformat): Likewise.
21310 * syntax.c (skip_chars): Likewise.
21312 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21313 This also lets GCC 4.6.0 generate slightly better loop code.
21315 * callint.c (Fcall_interactively): <, not <=, for optimization.
21316 (Fcall_interactively): Count the number of arguments produced,
21317 not the number of arguments given. This is simpler and lets GCC
21318 4.6.0 generate slightly better code.
21320 * ftfont.c: Distingish more carefully between FcChar8 and char.
21321 The previous code passed unsigned char * to a functions like
21322 strlen and xstrcasecmp that expect char *, which does not
21323 conform to the C standard.
21324 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21325 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21326 char * when the C standard requires it.
21328 * keyboard.c (read_char): Remove unused var.
21330 * eval.c: Port to Windows vsnprintf (Bug#8435).
21331 Include <limits.h>.
21332 (SIZE_MAX): Define if the headers do not.
21333 (verror): Do not give up if vsnprintf returns a negative count.
21334 Instead, grow the buffer. This ports to Windows vsnprintf, which
21335 does not conform to C99. Problem reported by Eli Zaretskii.
21336 Also, simplify the allocation scheme, by avoiding the need for
21337 calling realloc, and removing the ALLOCATED variable.
21339 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21341 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21342 But keep the doprint source code for now, as we might revamp it
21343 and use it again (Bug#8435).
21344 * lisp.h (doprnt): Remove.
21345 * Makefile.in (base_obj): Remove doprnt.o.
21346 * deps.mk (doprnt.o): Remove.
21348 error: Print 32- and 64-bit integers portably (Bug#8435).
21349 Without this change, on typical 64-bit hosts error ("...%d...", N)
21350 was used to print both 32- and 64-bit integers N, which relied on
21351 undefined behavior.
21352 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21353 * lisp.h (error, verror): Mark as printf-like functions.
21354 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21355 Report overflow in size calculations when allocating printf buffer.
21356 Do not truncate output string at its first null byte.
21357 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21358 Truncate the output at a character boundary, since vsnprintf does not
21360 * charset.c (check_iso_charset_parameter): Convert internal
21361 character to string before calling 'error', since %c now has the
21363 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21364 overflow when computing char to be passed to 'error'. Do not
21365 pass Lisp_Object to 'error'; pass the integer instead.
21366 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21367 formatted with plain %d.
21369 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21371 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21373 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21375 * xterm.c (x_catch_errors): Remove duplicate declaration.
21377 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21379 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21381 2011-04-10 Jim Meyering <meyering@redhat.com>
21383 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21384 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21385 return ssize_t not "int", and use size_t as the buffer length.
21386 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21387 * gnutls.h: Update declarations.
21388 * process.c (read_process_output): Use ssize_t, to match.
21389 (send_process): Likewise.
21391 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21393 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21395 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21397 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21398 Use unsigned char, to match FcChar8 type definition.
21400 * xterm.c (handle_one_xevent):
21401 * xmenu.c (create_and_show_popup_menu):
21402 * xselect.c (x_decline_selection_request)
21403 (x_reply_selection_request): Avoid type-punned deref of X events.
21405 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21407 Fix some uses of `int' instead of EMACS_INT.
21408 * search.c (string_match_1, fast_string_match)
21409 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21410 (scan_buffer, find_next_newline_no_quit)
21411 (find_before_next_newline, search_command, Freplace_match)
21412 (Fmatch_data): Make some `int' variables be EMACS_INT.
21414 * xdisp.c (display_count_lines): 3rd argument and return value now
21415 EMACS_INT. All callers changed.
21416 (pint2hrstr): Last argument is now EMACS_INT.
21418 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21419 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21420 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21421 (decode_coding_utf_16, decode_coding_emacs_mule)
21422 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21423 (decode_coding_ccl, decode_coding_charset)
21424 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21425 (decode_coding_iso_2022, decode_coding_emacs_mule)
21426 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21427 <char_offset, last_offset>: Declare EMACS_INT.
21428 (encode_coding_utf_8, encode_coding_utf_16)
21429 (encode_coding_emacs_mule, encode_invocation_designation)
21430 (encode_designation_at_bol, encode_coding_iso_2022)
21431 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21432 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21434 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21435 (encode_invocation_designation): Last argument P_NCHARS is now
21437 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21438 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21440 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21443 * ccl.c (Fccl_execute_on_string): Declare some variables
21446 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21448 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21450 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21452 * process.c (Fformat_network_address): Doc fix.
21454 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21456 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21458 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21460 * keyboard.c (read_char): Call Lisp function help-form-show,
21461 instead of using internal_with_output_to_temp_buffer.
21462 (Qhelp_form_show): New var.
21463 (syms_of_keyboard): Use DEFSYM macro.
21465 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21467 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21469 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21471 * process.c (Flist_processes): Remove to Lisp.
21472 (list_processes_1): Delete.
21474 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21476 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21478 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21480 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21482 Fix more problems found by GCC 4.6.0's static checks.
21484 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21486 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21488 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21490 * xdisp.c (vmessage): Mark as a printf-like function.
21492 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21494 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21496 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21497 printf-like functions.
21498 (tiff_load): Add casts to remove these marks before passing them
21499 to system-supplied API.
21501 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21503 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21504 This avoids several warnings with gcc -Wstrict-overflow.
21505 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21506 directly, rather than having caller test rule sign. This avoids
21507 some unnecessary tests.
21508 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21509 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21510 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21512 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21513 (xfont_open): Avoid unnecessary tests.
21515 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21517 * composite.h, composite.c (composition_gstring_put_cache):
21518 Use EMACS_INT, not int, for length.

21521 breaking out part of COMPOSITION_DECODE_RULE.
21522 (COMPOSITION_DECODE_RULE): Use it.
21523 * composite.c (get_composition_id): Remove unused local vars,
21524 by using the new macro.
21526 * textprop.c (set_text_properties_1): Change while to do-while,
21527 since the condition is always true at first.
21529 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21530 (interval_deletion_adjustment): Return unsigned value.
21533 * process.c (list_processes_1, create_pty, read_process_output):

21545 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21546 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21547 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21549 * print.c (print_error_message): Avoid int overflow.
21551 * font.c (font_list_entities): Redo for clarity,
21552 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21554 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21555 (font_score): Avoid potential overflow in diff calculation.
21557 * fns.c (substring_both): Remove var that is set but not used.
21558 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21560 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21562 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21563 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21564 can always succeed if overflow has undefined behavior.
21566 * search.c (boyer_moore, wordify): Remove vars set but not used.
21567 (wordify): Omit three unnecessary tests.
21569 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21570 All callers changed. This avoids the need for an unused var.
21572 * casefiddle.c (casify_region): Remove var that is set but not used.
21574 * dired.c (file_name_completion): Remove var that is set but not used.
21576 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21578 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21579 (Finsert_file_contents): Remove unnecessary code checking fd.
21581 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21582 Check for integer overflow on size calculations.
21584 * buffer.c (Fprevious_overlay_change): Remove var that is set
21587 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21588 Remove vars that are set but not used.
21589 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21590 (timer_check_2): Mark vars as initialized.
21592 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21594 * image.c (lookup_image): Remove var that is set but not used.
21595 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21597 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21598 that are set but not used.
21600 * xfns.c (make_invisible_cursor): Don't return garbage
21601 if XCreateBitmapFromData fails (Bug#8410).
21603 * xselect.c (x_get_local_selection, x_handle_property_notify):
21604 Remove vars that are set but not used.
21606 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

21616 (map_tty_color) [!defined MSDOS]: Likewise.
21618 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21620 * coding.c: Remove vars that are set but not used.
21621 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21622 All callers changed.
21623 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21624 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21625 (decode_coding_charset): Remove vars that are set but not used.
21627 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21628 that is set but not used.
21630 * print.c (print_object): Remove var that is set but not used.
21632 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21633 The gnulib version avoids calling malloc in the usual case,
21634 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21635 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21636 * filelock.c (current_lock_owner): Likewise.
21637 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

21640 (emacs_readlink): New function.
21641 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21642 ../lib/careadlinkat.h.
21644 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21646 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21647 first non-nil return value).

21651 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21652 if not defined (Bug#8403).

21661 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21662 and thereabouts. All callers changed.
21663 (get_per_char_metric): Remove parameter `f', unused since
21664 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21668 do not dereference NULL upon failed strdup
21669 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21670 (ns_get_family): Likewise.
21672 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21674 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

21711 (Fcommandp): Handle closures.
21712 (Feval): New `lexical' arg.
21713 (eval_sub): New function extracted from Feval. Use it almost

21722 but without exporting it to Lisp.
21724 * doc.c (Fdocumentation, store_function_docstring):
21725 * data.c (Finteractive_form): Handle closures.
21727 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21730 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21732 (exec_byte_code): New function extracted from Fbyte_code to handle new
21733 calling convention for byte-code-functions. Add new byte-codes.
21735 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21737 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21739 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21741 * xdisp.c (redisplay_internal): Fix prototype.
21743 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21745 * xdisp.c (SCROLL_LIMIT): New macro.
21746 (try_scrolling): Use it when setting scroll_limit.
21747 Limit scrolling to 100 screen lines.
21748 (redisplay_window): Even when falling back on "recentering",
21749 position point in the window according to scroll-conservatively,
21750 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21752 (try_scrolling): When point is above the window, allow searching
21753 as far as scroll_max, or one screenful, to compute vertical
21754 distance from PT to the scroll margin position. This prevents
21755 try_scrolling from unnecessarily failing when
21756 scroll-conservatively is set to a value slightly larger than the
21757 window height. Clean up the case of PT below the margin at bottom
21758 of window: scroll_max can no longer be INT_MAX. When aggressive
21759 scrolling is in use, don't let point enter the opposite scroll
21760 margin as result of the scroll.
21761 (syms_of_xdisp) <scroll-conservatively>: Document the
21762 threshold of 100 lines for never-recentering scrolling.
21764 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21766 * dispextern.h (move_it_by_lines):
21767 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21768 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21769 (message_log_check_duplicate): Remove parameters `prev_bol' and
21770 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21771 (redisplay_internal): Remove parameter `preserve_echo_area',
21772 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21774 * indent.c (Fvertical_motion):
21775 * window.c (window_scroll_pixel_based, Frecenter):
21776 Don't pass `need_y_p' to `move_it_by_lines'.
21778 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21780 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21781 steal a few bits to be more compact.
21782 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21783 Remove unneeded casts.
21785 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21787 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21789 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21790 binding" message (bug#7967).
21792 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21794 Fix more problems found by GCC 4.6.0's static checks.
21796 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21797 Remove unused local var.
21799 * editfns.c (Fmessage_box): Remove unused local var.
21801 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21802 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21803 Omit unused local vars.
21804 * window.c (shrink_windows): Omit unused local var.
21805 * menu.c (digest_single_submenu): Omit unused local var.
21806 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21807 Omit unused local var.
21809 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21810 Don't assume string length fits in int.
21811 (keyremap_step, read_key_sequence): Use size_t for sizes.
21812 (read_key_sequence): Don't check last_real_key_start redundantly.
21814 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21815 instead of alloca (Bug#8344).
21817 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21818 (Fbacktrace_frame): Don't assume nframes fits in int.
21820 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21822 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21825 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21827 * cm.c (calccost): Turn while-do into do-while, for clarity.
21829 * keyboard.c (syms_of_keyboard): Use the same style as later
21830 in this function when indexing through an array. This also
21831 works around GCC bug 48267.
21833 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21835 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21837 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21838 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21840 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21841 This avoids undefined behavior on integer overflow, and is a bit
21842 more convenient anyway since it is compared to a size_t variable.
21844 Variadic C functions now count arguments with size_t, not int.
21845 This avoids an unnecessary limitation on 64-bit machines, which
21846 caused (substring ...) to crash on large vectors (Bug#8344).
21847 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21848 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21849 All variadic functions and their callers changed accordingly.

21852 * editfns.c (general_insert_function): Likewise.
21853 * eval.c (struct backtrace.nargs, interactive_p)
21854 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21855 (funcall_lambda, mark_backtrace): Likewise.
21856 * fns.c (concat): Likewise.
21857 * frame.c (x_set_frame_parameters): Likewise.
21858 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21859 0 if not found, not -1. All callers changed.
21861 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21862 (stack_copy_size): Now size_t, not int.
21863 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21865 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21867 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21868 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21869 All callers changed.
21871 * lisp.h (multibyte_char_to_unibyte):
21872 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21873 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21874 * character.h (CHAR_TO_BYTE8):
21875 * cmds.c (internal_self_insert):
21876 * editfns.c (general_insert_function):
21877 * keymap.c (push_key_description):
21878 * search.c (Freplace_match):
21879 * xdisp.c (message_dolog, set_message_1): All callers changed.
21881 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21883 * keyboard.c (safe_run_hook_funcall): New function.
21884 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21885 don't set the hook to nil, but remove the offending function instead.
21886 (Qcommand_hook_internal): Remove, unused.
21887 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21888 Vcommand_hook_internal.
21890 * eval.c (enum run_hooks_condition): Remove.
21891 (funcall_nil, funcall_not): New functions.
21892 (run_hook_with_args): Call each function through a `funcall' argument.
21893 Remove `cond' argument, now redundant.
21894 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21895 (Frun_hook_with_args_until_failure): Adjust accordingly.
21896 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21898 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21900 * dispextern.h (string_buffer_position): Remove declaration.
21902 * print.c (strout): Remove parameter `multibyte', unused since
21903 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21905 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21906 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21907 All callers changed.
21909 * w32.c (_wsa_errlist): Use braces for struct initializers.
21911 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21912 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21913 All callers changed.
21914 (string_buffer_position): Likewise. Also, make static (it's never
21915 used outside xdisp.c).
21916 (cursor_row_p): Remove parameter `w', unused since
21917 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21919 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21920 All callers changed.
21922 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21924 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21930 (ns_update_auto_hide_menu_bar): New functions.
21931 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21935 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21937 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21939 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21941 2011-03-27 Glenn Morris <rgm@gnu.org>

21944 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21945 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21946 Replace SIGTYPE with void everywhere.
21947 * s/usg5-4-common.h (SIGTYPE): Remove definition.

21950 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21952 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21953 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21955 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21957 * w32.c (read_unc_volume): Use parameter `henum', instead of
21958 global variable `wget_enum_handle'.
21960 * keymap.c (describe_vector): Remove parameters `indices' and
21961 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21964 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21966 * keyboard.c (timer_check): Remove parameter `do_it_now',
21967 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21968 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21969 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
21971 * keyboard.c (read_char):
21972 * w32menu.c (w32_menu_display_help):
21973 * xmenu.c (show_help_event, menu_help_callback):
21974 Adjust calls to `show_help_echo'.
21976 * gtkutil.c (xg_maybe_add_timer):
21977 * keyboard.c (readable_events):
21978 * process.c (wait_reading_process_output):
21979 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21981 * insdel.c (adjust_markers_gap_motion):
21982 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
21983 (gap_left, gap_right): Don't call it.
21985 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

22032 Don't pass uninitialized region to CombineRgn.
22034 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22036 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22037 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22038 (Fx_close_connection): Remove unused variable `i'.

22056 2011-03-23 Julien Danjou <julien@danjou.info>
22058 * term.c (Fsuspend_tty, Fresume_tty):
22059 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22060 * window.c (temp_output_buffer_show):

22066 * cmds.c (internal_self_insert):
22067 * callint.c (Fcall_interactively):
22068 * buffer.c (Fkill_all_local_variables):
22069 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22071 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22072 unconditionally since it does the check itself.
22074 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22076 Fix more problems found by GCC 4.5.2's static checks.
22078 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22079 the first time through the loop, since we know p0 < p1 then.
22080 This also avoids a gcc -Wstrict-overflow warning.
22082 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22083 leading to a memory leak, possible in functions like
22084 load_charset_map_from_file that can allocate an unbounded number
22085 of objects (Bug#8318).
22087 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22088 that could (at least in theory) be that large.
22090 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22091 This is less likely to overflow, and avoids undefined behavior if
22092 overflow does occur. All callers changed. Use strtoul to scan
22093 for the unsigned long integer.
22094 (pint2hrstr): Simplify and tune code slightly.
22095 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22097 * scroll.c (do_scrolling): Work around GCC bug 48228.
22098 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22100 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22101 This also avoids a warning with gcc -Wstrict-overflow.
22102 (validate_x_resource_name): Simplify count usage.
22103 This also avoids a warning with gcc -Wstrict-overflow.
22105 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22108 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22110 * process.c (Fmake_network_process): Use socklen_t, not int,
22111 where POSIX says socklen_t is required in portable programs.
22112 This fixes a porting bug on hosts like 64-bit HP-UX, where
22113 socklen_t is wider than int (Bug#8277).
22114 (Fmake_network_process, server_accept_connection):
22115 (wait_reading_process_output, read_process_output):
22118 * process.c: Rename or move locals to avoid shadowing.
22119 (list_processes_1, Fmake_network_process):
22120 (read_process_output_error_handler, exec_sentinel_error_handler):
22121 Rename or move locals.
22122 (Fmake_network_process): Define label "retry_connect" only if needed.
22123 (Fnetwork_interface_info): Fix pointer signedness.
22124 (process_send_signal): Add cast to avoid pointer signedness problem.
22125 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22126 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22128 Make tparam.h and terminfo.c consistent.
22129 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22130 Include tparam.h instead, since it declares them.
22131 * cm.h (PC): Remove extern decl; tparam.h now does this.
22132 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22133 * terminfo.c: Include tparam.h, to check interfaces.
22134 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22135 (tparam): Adjust signature to match interface in tparam.h;
22136 this removes some undefined behavior. Check that outstring and len
22137 are zero, which they always are with Emacs.
22138 * tparam.h (PC, BC, UP): New extern decls.
22140 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22141 (xftfont_open): Rename locals to avoid shadowing.
22143 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22144 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22145 (OTF_TAG_SYM): Omit macro if not needed.
22146 (ftfont_list): Remove unused local.
22147 (get_adstyle_property, ftfont_pattern_entity):
22148 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22149 Rename locals to avoid shadowing.
22151 * xfont.c (xfont_list_family): Mark var as initialized.
22153 * xml.c (make_dom): Now static.
22155 * composite.c (composition_compute_stop_pos): Rename local to

22192 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22194 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22195 This should get cleaned up, so that child_setup has the
22196 same signature on all platforms.

22360 (Fmemory_limit): Cast sbrk's returned value to char *.
22362 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22368 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22369 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22370 to use the following functions instead of these macros.
22371 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22372 EMACS_INT, since callers assume the returned value fits in int.
22373 (upcase1): Likewise, for UPCASE_TABLE.
22374 (uppercasep, lowercasep, upcase): New static inline functions.
22375 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22385 (regex_compile, re_match_2_internal): Mark locals as initialized.
22386 (RETALLOC_IF): Define only if needed.
22387 (WORDCHAR_P): Likewise. This one is never needed, but is used
22388 only in a comment talking about a compiler bug, so put inside
22389 the #if 0 of that comment.
22390 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22391 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22418 New macros, so that the caller can use some names other than
22419 gcpro1, gcpro2, etc.
22420 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22422 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22423 argument, for consistency with GCPRO2_VAR, etc: it is now the
22424 prefix of the variable, not the variable itself. All uses
22426 * dired.c (directory_files_internal, file_name_completion):
22427 Rename locals to avoid shadowing.
22429 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22430 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22431 dired.c's scmp function, had undefined behavior.
22432 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22433 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22434 * buffer.h: ... to here, because these macros use current_buffer,
22435 and the new implementation with inline functions needs to have
22436 current_buffer in scope now, rather than later when the macros
22438 (downcase, upcase1): New static inline functions.
22439 (DOWNCASE, UPCASE1): Reimplement using these functions.
22440 This avoids undefined behavior in expressions like
22441 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22442 from race conditions in accessing the global variables
22443 case_temp1 and case_temp2.
22444 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22445 * lisp.h (case_temp1, case_temp2): Remove their decls.
22446 * character.h (ASCII_CHAR_P): Move from here ...
22447 * lisp.h: ... to here, so that the inline functions mentioned
22448 above can use them.
22450 * dired.c (directory_files_internal_unwind): Now static.
22452 * fileio.c (file_name_as_directory, directory_file_name):

22455 (file_name_as_directory): Use const pointers when appropriate.
22456 (Fexpand_file_name): Likewise. In particular, newdir might
22457 point at constant storage, so make it a const pointer.
22458 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22459 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22461 (Fset_file_times, Finsert_file_contents, auto_save_error):

22466 to avoid shadowing.
22468 * marker.c (bytepos_to_charpos): Remove; unused.
22470 * lisp.h (verify_bytepos, count_markers): New decls,
22471 so that gcc does not warn that these functions aren't declared.
22473 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22474 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22475 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22476 (copy_text): Remove unused local var.
22478 * filelock.c (within_one_second): Now static.
22479 (lock_file_1): Rename local to avoid shadowing.
22481 * buffer.c (fix_overlays_before): Mark locals as initialized.
22482 (fix_start_end_in_overlays): Likewise. This function should be
22483 simplified by using pointers-to-pointers, but that's a different
22485 (switch_to_buffer_1): Now static.
22486 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22487 (report_overlay_modification): Rename locals to avoid shadowing.
22489 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22490 Fix pointer signedness issue.
22491 (sys_subshell): Mark local as volatile if checking for lint,
22492 to suppress a gcc -Wclobbered warning that does not seem to be right.
22493 (MAXPATHLEN): Define only if needed.
22495 * process.c (serial_open, serial_configure): Move decls from here ...
22496 * systty.h: ... to here, so that they can be checked.
22498 * fns.c (get_random, seed_random): Move extern decls from here ...
22499 * lisp.h: ... to here, so that they can be checked.
22501 * sysdep.c (reset_io): Now static.

22507 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22508 (DENSE_TABLE_SIZE): Remove; unused.
22509 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22510 (describe_map_tree):
22511 Rename locals to avoid shadowing.
22513 * keyboard.c: Declare functions static if they are not used elsewhere.

22598 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22599 These macros can no longer be used for assignment.
