3 * frame.h (struct frame): Drop resx and resy because the same data is
4 available from window system-specific output context. Adjust users.
5 (default_pixels_per_inch_x, default_pixels_per_inch_y): New
6 functions to provide defaults when no window system available.
7 (FRAME_RES_X, FRAME_RES_Y): New macros.

66 Use getFilename and getDirectory.
67 (getFilename, getDirectory): New methods for EmacsSavePanel and
69 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

113 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
114 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE

117 f->want_fullscreen flag after changing the frame size. If the
118 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.

123 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
124 too so that these builds can use Cygwin's file conversion
125 functions. (We've been building and linking cygw32.o all along
126 and just not using it.)
128 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
130 File synchronization fixes (Bug#13944).
131 * Makefile.in (LIB_FDATASYNC): New macro.

141 * w32term.c (w32_read_socket): If the Emacs frame is being
142 activated, call w32fullscreen_hook, to make sure the new frame
143 dimensions are in effect. (Bug#13937)
145 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
147 * xdisp.c (init_iterator): Simplify because both character and byte
148 positions are either specified or -1. Add eassert. Adjust comment.
149 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
150 character and byte positions can be obtained from marker.

167 a function pointer type; the C Standard requires this.
169 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
170 Include <sys/param.h> unconditionally, as that works elsewhere and
171 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
172 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
175 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
177 * insdel.c (adjust_after_replace): Use bool for boolean.
179 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

204 common file dialog code.
206 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
207 can just use du like other systems.
209 * coding.c (from_unicode_buffer): Declare.
210 * coding.c (from_unicode_buffer): Implement.
212 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

253 (adjust_after_insert): Call adjust_after_replace with the new arg
256 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
258 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
259 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
260 from Elisp via unread-command-events.
262 * keyboard.c (access_keymap_keyremap): Accept nil return value from
263 functions to mean "no change".
265 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
267 region-cache.c, scroll.c, search.c: Use bool for booleans.

269 * scroll.c (do_scrolling, do_direct_scrolling):
270 * search.c (struct regexp_cache, compile_pattern_1)
271 (compile_pattern, string_match_1, search_command)
272 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
273 (search_regs_saved, Fregexp_quote):
274 Use bool for boolean.
275 * region-cache.c (region_cache_forward, region_cache_backward):
276 Fix comments to match code: these functions return int, not boolean.
278 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
280 * search.c (find_newline): Accept start and end byte positions
281 as arguments and allow -1 if not known.

287 Adjust call to find_newline.
288 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

291 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
292 (get_visually_first_element, move_it_vertically_backward): Likewise.
293 Obtain byte position from the display iterator, where appropriate.
295 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

316 to match other functions accepting character and byte positions.
318 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
319 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
320 when you need just to move to the previous buffer position.
321 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
323 2013-03-07 Eli Zaretskii <eliz@gnu.org>
325 * .gdbinit (prowlims): Display the enabled_p flag of the row.
327 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>

396 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
398 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
399 * sysdep.c (list_system_processes)
400 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
401 Make it a stub in this case; otherwise the build might fail,
402 and this code hasn't been tested on such hosts anyway.
403 Problem reported by Nelson H. F. Beebe in
404 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
405 and analyzed by Jérémie Courrèges-Anglas in
406 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
408 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
410 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
411 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
412 (get_visually_first_element, move_it_vertically_backward): Ajust users.
413 * bidi.c (bidi_find_paragraph_start): Likewise.
414 * indent.c (vmotion): Likewise.
416 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
418 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
419 * filelock.c: Include <c-ctype.h>.
420 (MAX_LFINFO): New top-level constant.
421 (lock_info_type): Remove members pid, boot_time. Add members at,
422 dot, colon. Change user member to be the entire buffer, not a
423 pointer. This allows us to handle the case where a foreign
424 pid or boot time exceeds the local range. All uses changed.
425 (LINKS_MIGHT_NOT_WORK): New constant.
426 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
427 (defined_WINDOWSNT): Remove.
428 (MAKE_LOCK_NAME, file_in_lock_file_name):
429 Always use .#FILE (not .#-FILE) for the file lock,
430 even if it is a regular file.
431 (rename_lock_file): New function.
432 (create_lock_file): Use it.
433 (create_lock_file, read_lock_data):
434 Prefer a symbolic link for the lock file, falling back on a
435 regular file if symlinks don't work. Do not try to create
436 symlinks on MS-Windows, due to security hassles. Stick with
437 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
438 link, rename, unlink, mkstemp) when creating locks, as a GNUish
439 host may be using a Windowsish file system, and cannot use
440 MS-Windows-only system calls. Fall back on mktemp if mkstemp
441 doesn't work. Don't fail merely because of a symlink-contents
442 length limit in the current file system; fall back on regular
443 files. Increase the symlink contents length limit to 8 KiB, this
444 should be big enough for any real use and doesn't crunch the
446 (create_lock_file, lock_file_1, read_lock_data):
447 Simplify allocation of lock file buffers now that they fit in 8 KiB.
448 (lock_file_1): Return error number, not bool. All callers changed.
449 (ELOOP): New macro, if not already defined.
450 (read_lock_data): Return size of lock file contents, not Lisp object.
451 All callers changed. Handle a race condition if some other process
452 replaces a regular-file lock with a symlink lock or vice versa,
453 while we're trying to read the lock.
454 (current_lock_owner): Parse contents more carefully, to help avoid
455 confusing a regular-file lock with some other application's use
456 of the file. Check for lock file contents being too long, or
457 not parsing correctly.
458 (current_lock_owner, lock_file):
459 Allow foreign pid and boot times that exceed the local range.
460 (current_lock_owner, lock_if_free, lock_file):
461 Simplify allocation of lock file contents.
462 * w32.c (sys_rename_replace): New function, containing most of
463 the contents of the old sys_rename.
464 (sys_rename): Use it.
465 (fchmod): New dummy function.
466 * w32.h (sys_rename_replace, fchmod): New decls.
468 2013-03-05 Eli Zaretskii <eliz@gnu.org>
470 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
471 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
472 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
473 <dmantipov@yandex.ru>.
475 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
477 * composite.c (get_composition_id, fill_gstring_header):
478 Use make_uninit_vector where appropriate.
479 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
480 * xselect.c (clean_local_selection_data): Likewise.

484 Fix misuse of ImageMagick that caused core dump (Bug#13846).
485 * image.c (imagemagick_load_image): Calculate height and width
486 after flattening the image, not before.
488 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
490 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
491 * ftfont.c (ftfont_shape_by_flt): Likewise.
492 * w32uniscribe.c (uniscribe_shape): Likewise.
494 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
496 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
497 The old approach, which fell back on DIR/.#FILE.0 through
498 DIR/.#FILE.9, had race conditions that could not be easily fixed.
499 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
500 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
501 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
502 because the locking mechanism was never reliable in that case).
503 This patch fixes this and other bugs discovered by a code
504 inspection that was prompted by
505 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
506 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
507 to avoid interoperability problems between the MS-Windows and
508 non-MS-Windows implementations. MS-Windows and non-MS-Windows
509 instances of Emacs now ignore each others' locks.
510 * filelock.c (defined_WINDOWSNT): New constant.
511 (MAKE_LOCK_NAME, fill_in_lock_file_name):
512 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
513 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
514 regular files on MS-Windows hosts.
515 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
516 Use SAFE_ALLOCA to avoid problems with long file names.
517 (MAX_LFINFO): Now a local constant, not a global macro.
518 (IS_LOCK_FILE): Remove.
519 (lock_file_1): Don't inspect errno if symlink call succeeds;
521 (lock_file): Document that this function can return if lock
523 (lock_file): Don't access freed storage.
525 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

529 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
531 * textprop.c: Use bool for booleans.
532 (validate_interval_range, Fadd_text_properties)
533 (Fremove_text_properties): Prefer bool to int when either works.
535 2013-03-02 Eli Zaretskii <eliz@gnu.org>
537 * textprop.c (Fadd_text_properties, Fremove_text_properties):
538 If the interval tree changes as a side effect of calling
539 modify_region, re-do processing starting from the call to
540 validate_interval_range. (Bug#13743)
542 2013-02-28 Eli Zaretskii <eliz@gnu.org>
544 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
547 2013-02-27 Eli Zaretskii <eliz@gnu.org>
549 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
550 _SH_DENYRW flag, instead of emacs_open, to deny any other process
551 access to the lock file until it is written and closed.
554 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
556 * callint.c (Qcall_interactively):
557 * macros.c (Qexecute_kbd_macro):
560 2013-02-26 Bastien Guerry <bzg@gnu.org>
562 * window.c (Frecenter): Tiny docstring enhancement.
564 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
566 Minor textprop integer cleanup.
567 * intervals.h, textprop.c (add_text_properties_from_list):
568 Return void, not int, since nobody uses the return value.
569 * textprop.c (validate_plist, add_properties, remove_properties)
570 (Fadd_text_properties):
571 Don't assume list length fits in int.
572 (interval_has_all_properties, interval_has_some_properties)
573 (interval_has_some_properties_list, add_properties, remove_properties)
574 (Fadd_text_properties, Fremove_text_properties)
575 (Fremove_list_of_text_properties, text_property_stickiness):
576 Use bool for booleans.
577 (Fadd_text_properties, Fremove_text_properties):
578 (Fremove_list_of_text_properties):
579 Reindent do-while as per GNU style.
581 2013-02-25 Eli Zaretskii <eliz@gnu.org>
583 Implement CLASH_DETECTION for MS-Windows.
585 * filelock.c [WINDOWSNT]: Include w32.h.
586 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
587 function of that name. Up-case the macro arguments.
588 (IS_LOCK_FILE): New macro.
589 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
590 (create_lock_file): New function, with body extracted from
592 [WINDOWSNT]: Implement lock files by writing a regular file with
593 the lock information as its contents.
594 (read_lock_data): New function, on Posix platforms just calls
596 [WINDOWSNT]: Read the lock info from the file.
597 (current_lock_owner): Call read_lock_data instead of calling
598 emacs_readlinkat directly.
599 (lock_file) [WINDOWSNT]: Run the file name through
602 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
603 just check if the process by that PID exists.
605 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
606 also present, as doing so will fail to error out if the file
609 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
611 * textprop.c (Fadd_text_properties, Fremove_text_properties)
612 (Fremove_list_of_text_properties): Skip all of the intervals in
613 the region between START and END that already have resp. don't
614 have the requested properties, not just the first one.
615 Add assertions that the loop afterwards always modifies the
616 properties. (Bug#13743)
618 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
620 * callint.c (Fcall_interactively): Use the right lexical environment

628 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
629 (START_FILES): Remove. All uses removed.
630 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
631 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
632 (buildobj.h): Use it.
633 ($(ALLOBJS)): Depend on globals.h.
634 (temacs$(EXEEXT)): Use $(ALLOBJS).
635 * autodeps.mk (ALLOBJS): Move to Makefile.in.
636 * deps.mk (vm-limit.o):

640 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
641 [__GNUC__ && !ORDINARY_LINK]: Remove.

645 (make_hdr): Use DATA_START instead of start_of_data.
646 * vm-limit.c: Move most of mem-limits.h's contents here.
647 (data_start): New decl. It's OK if this is approximate,
648 so simplify-away some unnecessary exactness.
649 (POINTER): Remove; all uses removed.
650 (data_space_start): Now char *, to avoid casts.
651 (exceeds_lisp_ptr): New function, replacing the old
652 EXCEEDS_LISP_PTR macro. All uses changed.
653 (check_memory_limits): Simplify and remove casts.
654 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

659 * xdisp.c (set_message): Only check for debug-on-message if STRING
660 is a string. (Bug#13797)
662 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>

667 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
668 and diagnosed by Andreas Schwab in
669 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
671 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
673 Assume C89 or better.
674 * ralloc.c (SIZE, POINTER, NIL):
675 * vm-limit.c (POINTER):
676 Remove, replacing all uses with C89 equivalents. These old
677 symbols were present only for porting to pre-C89 platforms.
679 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
681 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
682 This avoids warning messages reported as part of Bug#13546.
684 2013-02-21 Ken Brown <kbrown@cornell.edu>

695 (syms_of_keyboard): Adjust accordingly.
697 2013-02-19 Daniel Colascione <dancol@dancol.org>
699 * sheap.c (report_sheap_usage): Use message, not message1, so
700 that we don't try to create a buffer while we're in the middle
701 of dumping Emacs. Explain why.
703 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
705 * search.c (find_newline): Return byte position in bytepos.
707 (find_next_newline_no_quit, find_before_next_newline):
708 Add bytepos argument.

715 (get_visually_first_element, move_it_vertically_backward):
716 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
718 2013-02-19 Eli Zaretskii <eliz@gnu.org>
720 * w32proc.c (new_child): Avoid leaking handles if the subprocess
721 resources were not orderly released.

726 the leftmost nor the rightmost, redraw both the left and the right
727 vertical borders. (Bug#13723)

749 * w32.c (sys_chown): Remove unused function.
751 * w32term.c <input_signal_count>: Declare 'volatile'
752 unconditionally. (Bug#9066)
754 * w32.c (set_errno): Reset h_errno and don't set it to any other
755 value. Set errno instead.
756 (check_errno): Reset h_errno.

770 * keyboard.c (read_char): Fix calculation of auto-save time out
771 when auto-save-timeout is less than 4. (Bug#13720)
773 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

781 (socket_to_fd): Add assertion against indexing fd_info[] with a
782 value that is out of bounds.
783 (sys_accept): If fd is negative, do not set up the child_process
784 structure for reading.

800 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
802 Fix AIX port (Bug#13650).
803 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
804 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
805 was #undeffed earlier, so it cannot be used as a macro here.
806 Use the constant and not the macro.
808 2013-02-15 Eli Zaretskii <eliz@gnu.org>
810 * w32proc.c (new_child): If no vacant slots are found in
811 child_procs[], make another pass looking for slots whose process
812 has exited or died. (Bug#13546)
814 * w32.c (sys_pipe): When failing due to file descriptors above
815 MAXDESC, set errno to EMFILE.
816 (_sys_read_ahead): Update cp->status when failing to read serial
817 communications input, so that the status doesn't stay at
818 STATUS_READ_IN_PROGRESS. (Bug#13546)
820 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
822 * gtkutil.c (tb_size_cb): New function.
823 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
825 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
827 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
830 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
832 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
834 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
836 * font.c (font_range): Add pos_byte argument. Adjust comment
838 * font.h (font_range): Adjust prototype.
839 * composite.c (autocmp_chars): Pass byte position to font_range.
840 Break long line. Remove useless prototype and format comment.
842 2013-02-13 Glenn Morris <rgm@gnu.org>
844 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
846 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
848 Improve AIX port some more (Bug#13650).
849 With this, it should be as good as it was in 23.3, though it's
850 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
851 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
852 * unexaix.c (start_of_text): Remove.
853 (_data, _text): Declare as char[], not int, as AIX manual suggests.
854 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
855 (orig_load_scnptr, orig_data_scnptr):
856 Now off_t, not long, since they are file offsets.
857 (make_hdr): Use _data, not start_of_data ().
858 This is the key part of the fix.
859 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
860 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
862 * pre-crt0.c (data_start): Initialize to 1.
863 This ports to compilers that optimize the external declaration
864 'int x = 0;' as if it were 'int x;' to shrink the executable.
866 Improve AIX port (Bug#13650).
867 This doesn't fix the bug, but it makes progress: Emacs builds now.
868 * unexaix.c: Include inttypes.h, stdarg.h.
869 (report_error, report_error_1): Mark as _Noreturn.
870 (report_error): Don't report the wrong errno.
871 (report_error_1): Now varargs. All callers changed.
872 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
873 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
874 (write_ptr): Use %p to print address rather than %lx and a cast
875 to unsigned long. Grow buffer a bit, to be safer.
877 2013-02-13 Eli Zaretskii <eliz@gnu.org>
879 * bidi.c (bidi_resolve_neutral): After finding the next
880 non-neutral character, accept NEUTRAL_ON type as well, because
881 directional control characters, such as LRE and RLE, have their
882 type converted to that by bidi_resolve_weak. This avoids aborts
883 when LRE/RLE follows a run of neutrals.
884 (bidi_move_to_visually_next): Assert that return value of
885 bidi_peek_at_next_level is non-negative. Negative values will
888 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
890 Minor getenv-related fixes.
891 * callproc.c (Fcall_process_region) [!DOS_NT]:
892 Avoid unnecessary duplicate call to getenv.
893 * callproc.c (init_callproc):
894 * dispnew.c (init_display):
895 * sysdep.c (sys_subshell):
896 Omit unnecessary cast of getenv or egetenv.
898 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
900 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
903 2013-02-12 Eli Zaretskii <eliz@gnu.org>
905 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
907 (display_line): Set w->region_showing to the value of
908 it->region_beg_charpos, not to -1. This fixes redisplay
909 optimization when cursor is moved up after M->. (Bug#13623)
911 (try_scrolling): Scroll text up more if point is too close to ZV
912 and inside the scroll margin. This makes sure point is moved
913 outside the scroll margin in these cases.
915 * window.h (struct window): region_showing can no longer be
918 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
920 Tune by using memchr and memrchr.
921 * doc.c (Fsnarf_documentation):
922 * fileio.c (Fsubstitute_in_file_name):
923 * search.c (find_newline, scan_newline):
924 * xdisp.c (pos_visible_p, display_count_lines):
925 Use memchr and memrchr rather than scanning byte-by-byte.
926 * search.c (find_newline): Rename from scan_buffer.
927 Omit first arg TARGET, as it's always '\n'. All callers changed.
929 Clean up read_key_sequence a tiny bit more.
930 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
931 (read_key_sequence): Remove unused locals.
933 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
935 Clean up read_key_sequence a bit; reread active keymaps after first event.
936 * keyboard.c (read_char, read_char_x_menu_prompt)
937 (read_char_minibuf_menu_prompt):
938 Replace nmaps+maps with a single `map' arg.
939 (follow_key): Operate on a single map.
940 (active_maps): New function.
941 (test_undefined): Also return true for nil bindings.
942 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
943 a single (composed) keymap. Remember `first_event' to choose the right
944 set of active keymaps. Recompute the set of keymaps after receiving
945 the first event. Remove GOBBLE_FIRST_EVENT.
946 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
947 * keyboard.h (read_char): Update declaration.
948 * lread.c (read_filtered_event): Adjust call to read_char.
950 2013-02-11 Eli Zaretskii <eliz@gnu.org>
952 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
953 Don't use the limitation on backwards movement when lines are truncated
954 in the window. (Bug#13675)
956 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
958 * marker.c (set_marker_internal): If desired position is passed
959 as a marker, avoid call to buf_charpos_to_bytepos.
960 * window.c (Fset_window_point): Omit redundant type checking.
961 (Fset_window_start): Likewise. Format comment.
962 (window_scroll_pixel_based): Use set_marker_restricted_both
963 with character and byte positions obtained from an iterator.

967 2013-02-10 Eli Zaretskii <eliz@gnu.org>
969 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
970 When text lines are longer than window's screen lines, don't move back
971 too far. This speeds up some redisplay operations. (Bug#13675)

987 (sxhash_float): Return EMACS_UINT, for consistency with the other
989 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
990 non-static inline function and therefore can't use static vars.
991 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
992 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
993 with the other hash functions.
995 2013-02-09 Eli Zaretskii <eliz@gnu.org>
997 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
998 XXXXXX part of the temporary file pattern is not downcased even
999 when w32-downcase-file-names is non-nil. (Bug#13661)
1001 * xdisp.c (decode_mode_spec): Remove handling of %t.
1003 * msdos.c (careadlinkatcwd): Remove.
1005 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1007 * lread.c (skip_dyn_bytes): New function (bug#12598).

1043 argument is known to be a vector.
1044 * fns.c (Flocale_info): Likewise for ASET.
1045 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1046 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1048 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1050 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar

1061 if isFullscreen returns YES.
1062 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1063 (check_native_fs): New function.

1080 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1081 (syms_of_nsterm): Add ns-use-native-fullscreen.
1083 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1085 * fileio.c (Qchoose_write_coding_system): Now static.
1087 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1089 * xdisp.c (window_buffer_changed): region_showing can be negative,
1090 which still means region is being displayed.
1091 (redisplay_internal): Resurrect code that forced redisplay of the
1092 whole window when showing region and the mark has changed.
1093 Record the new mark position to allow redisplay optimizations.
1094 (display_line): If it->region_beg_charpos is non-zero, set the
1095 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1097 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1098 not bitfield of 1 bit.
1100 2013-02-03 Daniel Colascione <dancol@dancol.org>
1102 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1103 daemon mode works on cygw32 when Emacs is installed and not just
1106 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1108 Avoid file time stamp bug on MS-Windows (Bug#13149).
1109 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1110 as FAT32 doesn't update time stamps when truncating them.
1111 Also, check that a file time stamp is not a multiple of 100 ns;
1112 this should catch all instances of the problem on MS-Windows,
1113 as its native file system resolution is 100 ns or worse, and
1114 checking for a non-multiple of 100 ns should impose only a small
1115 overhead on systems with ns resolution.
1117 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1119 Avoid encoding file names on MS-Windows when they need to be run
1120 through dostounix_filename.
1121 * w32.c (normalize_filename): Accept an additional argument
1122 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1123 downcase it even if w32-downcase-file-names is non-nil.
1124 (dostounix_filename): Accept an additional argument MULTIBYTE and
1125 pass it to normalize_filename.
1126 (emacs_root_dir): Adjust.
1128 * msdos.h (dostounix_filename): Adjust prototype.
1130 * w32.h (dostounix_filename): Adjust prototype.
1132 * msdos.c (dostounix_filename): Accept an additional argument and
1134 (init_environment): Adjust callers of dostounix_filename.
1136 * fileio.c (Ffile_name_directory, file_name_as_directory)
1137 (directory_file_name, Fexpand_file_name)
1138 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1140 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1142 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1143 variables, as egetenv is case-insensitive for DOS_NT.
1145 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1146 with an encoded file name.
1148 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1149 Adjust calls to dostounix_filename.
1151 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1153 * unexw32.c (unexec): Adjust call to dostounix_filename.
1155 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1157 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1160 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1163 * callproc.c (Fcall_process): Make sure program name in PATH and
1164 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1165 is passed to exec/spawnve, which fails unless the file-name
1168 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1169 even if w32-quote-process-args is nil.
1171 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1173 Fix timestamp bug when write-region appends nothing (Bug#13149).
1174 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1175 the file's time stamp doesn't change if Emacs happens to write nothing
1176 to the file, and on a buggy file system this could cause Emacs to
1177 incorrectly infer that the file system doesn't have the bug.
1178 Avoid this problem by inhibiting the inference in this case.
1180 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1182 * window.h (struct window): Convert base_line_number, base_line_pos
1183 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1193 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1194 (try_scrolling, try_cursor_movement, redisplay_window)
1195 (try_window_reusing_current_matrix, try_window_id, display_line)
1196 (display_mode_lines, decode_mode_spec): Adjust users.
1197 * .gdbinit (pwinx): Do not print sequence_number.
1199 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1201 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1202 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1203 * dired.c: Include <fcntl.h>.
1204 (open_directory): New function, which uses open and fdopendir
1205 rather than opendir. DOS_NT platforms still use opendir, though.

1208 (directory_files_internal, Ffile_attributes): Use it.
1209 (file_attributes, file_name_completion_stat): First arg is now fd,
1210 not dir name. All uses changed. Use fstatat rather than lstat +
1212 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1213 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1214 (emacs_readlinkat): New function, with much of the old
1215 Ffile_symlink_p, but with an fd argument for speed.
1216 It uses readlinkat rather than careadlinkatcwd, so that it
1217 need not assume the working directory.
1218 (Ffile_symlink_p): Use it.
1219 * filelock.c (current_lock_owner): Use emacs_readlinkat
1220 rather than emacs_readlink.
1221 * lisp.h (emacs_readlinkat): New decl.
1222 (READLINK_BUFSIZE, emacs_readlink): Remove.
1223 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1224 (emacs_norealloc_allocator, emacs_readlink): Remove.
1225 This stuff is moved to fileio.c.
1226 * w32.c (fstatat, readlinkat): New functions.
1227 (careadlinkat): Don't check that fd == AT_FDCWD.

1239 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1240 (sys_close): Zero out the flags for the file descriptor before
1241 closing it. (Bug#13546)
1243 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1244 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1245 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1248 * w32.c (w32_get_long_filename, init_environment, readlink):
1249 Support file names encoded in DBCS codepages.
1250 (readlink): Use the current file-name-coding-system, not the ANSI
1251 codepage, to decode and handle targets of symlinks.
1253 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1255 * w32.c (opendir): Now accepts a 'const char *'.
1257 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1269 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1271 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

1274 debugging code. Adjust comment style here and there.
1275 * insdel.c (insert_1): Remove.
1276 * lisp.h (insert_1): Remove prototype.
1277 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1279 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1281 * w32.c (max_filename_mbslen): New function.
1282 (normalize_filename, readdir): Use it to detect locales where ANSI
1283 encoding of file names uses a double-byte character set (DBCS).
1284 If a DBCS encoding is used, advance by characters using
1285 CharNextExA, instead of incrementing a 'char *' pointer.
1286 Use _mbslwr instead of _strlwr. (Bug#13515)
1288 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1289 request of memory reservation to 1.7GB. (Bug#13065)

1299 Avoid redundant calls to strlen.
1301 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1303 Drop async_visible and async_iconified fields of struct frame.
1304 This is possible because async input is gone; for details, see
1305 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1306 * frame.h (struct frame): Remove async_visible and async_iconified
1307 members, convert garbaged to unsigned bitfield. Adjust comments.

1327 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1329 * xdisp.c (message2, message2_nolog): Remove functions.
1330 (message3, message3_nolog): Extract nbytes and multibyteness directly
1331 from the string. Change all callers.
1332 (message3_nolog): Don't set message_enable_multibyte since set_message
1333 will reset it anyway.
1334 (message1, message1_nolog): Use message3.
1335 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1336 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1337 (set_message): Drop all but the second arg, which has to be a string.

1351 * editfns.c (message_text, message_length): Remove vars.
1352 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1353 * fileio.c (auto_save_error): Use message3 instead of message2.

1384 * xdisp.c (mark_window_display_accurate): Simplify the loop
1385 assuming that the only one of vchild, hchild or buffer window
1386 slots is non-nil. Call mark_window_display_accurate_1 for

1406 * fileio.c (Finsert_file_contents): Revert code introduced at
1407 2013-01-18 in favor of the simpler and generally better fix.
1408 Save stack space by removing 'buffer' and reusing 'read_buf'
1411 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1413 * lisp.h (eabs): Define unconditionally (Bug#13419).
1414 The old "#if !defined (eabs)" was an unnecessary revenant of back
1415 when this macro was called "abs". Document 'eabs' better.
1417 2013-01-19 Glenn Morris <rgm@gnu.org>
1419 * fns.c (Frandom): Doc fix.
1421 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1423 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1424 segfault when there are lots of overlays.
1426 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1427 when there are lots of overlays.
1428 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1429 for the details and a way to reproduce.
1431 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1433 * fileio.c: Use O_APPEND to append.
1434 This corresponds better to the natural interpretation of "append",
1435 and avoids the need to open the output file twice, or to invoke
1436 lseek when APPEND is neither nil nor a number.
1437 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1438 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1439 file possibly twice, and lseeking to its end; this avoids the
1440 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1441 at the same time: the combination is never needed and apparently
1442 it doesn't work with DOS_NT.
1444 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1445 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1447 Allow floating-point file offsets.
1448 Problem reported by Vitalie Spinu in
1449 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1450 * fileio.c (emacs_lseek): Remove.
1451 (file_offset): New function.
1452 (Finsert_file_contents, Fwrite_region): Use it.
1454 2013-01-19 Chong Yidong <cyd@gnu.org>
1456 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1457 aborting on Fsignal (Bug#13289).
1459 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1461 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1462 set_file_security as failure due to insufficient privileges.
1463 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1464 (fstat): Return owner and group like 'stat' and 'lstat' do.
1466 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1468 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1469 The bug was observed on Ubuntu operating inside a virtual machine,
1470 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1471 The workaround introduces a race condition on non-buggy hosts,
1472 but it's an unlikely race and anyway there's a nearly identical
1473 nearby race that can't be fixed.
1474 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1476 (Fwrite_region): Test for file system time stamp bug.
1477 (init_fileio): New function.
1478 * lisp.h (init_fileio): Declare it.
1479 * emacs.c (main): Call it.
1481 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1482 and make it more consistent with other stat-failure diagnostics.

1486 Fix crash when inserting data from non-regular files.
1487 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1488 for the error description produced by valgrind.
1489 * fileio.c (read_non_regular): Rename to read_contents.
1490 Free Lisp_Save_Value object used to pass parameters.
1491 (read_non_regular_quit): Rename to read_contents_quit.
1492 (Finsert_file_contents): Redesign internal file reading loop to adjust
1493 gap and end positions after each read and so help make_gap to work
1494 properly. Do not signal an I/O error too early and so do not leave
1495 not yet decoded characters in a buffer, which was the reason of
1496 redisplay crash. Use list2 to build return value. Adjust comments.
1498 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1500 Close a race when statting and reading files (Bug#13149).
1501 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1502 This avoids a race if the file is renamed between stat and open.
1503 This race is not the problem originally noted in Bug#13149;
1504 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

1514 * alloc.c (format_save_value): Rename to make_save_value.
1515 (make_save_pointer): New function.
1516 (record_xmalloc): Use make_save_pointer.
1517 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:

1536 (map_keymap_char_table_item): Adjust accordingly.
1537 * fileio.c (non_regular_fd, non_regular_inserted)
1538 (non_regular_nbytes): Remove.
1539 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1540 Use format_save_value to pass parameters to read_non_regular.
1541 (read_non_regular): Use XSAVE_ macros to extract parameters.
1543 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1545 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1547 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1549 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1550 extraction from any Lisp_Save_Value slot. Add type checking.
1551 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1552 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1553 * xselect.c: All users changed.
1555 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1566 (save_excursion_restore): Use XSAVE_OBJECT.
1568 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1570 Avoid needless casts with XSAVE_POINTER.

1573 * fileio.c (do_auto_save_unwind):
1574 * gtkutil.c (pop_down_dialog):
1575 * keymap.c (map_keymap_char_table_item):
1576 * lread.c (load_unwind):
1577 * nsmenu.m (pop_down_menu):

1587 car and cdr becomes protected with the backtrace entry.
1589 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1591 Make Lisp_Save_Value more versatile storage for up to four objects.

1601 (free_save_value): Likewise.
1602 (mark_object): Likewise.
1603 * editfns.c (save_excursion_save): Pack everything within
1604 Lisp_Save_Value and so avoid xmalloc.
1605 (save_excursion_restore): Adjust to match new layout. Use free_misc
1606 because we do not allocate extra memory any more. Add eassert.
1607 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1608 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1620 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1622 Fix SIGDANGER handlers, for AIX (Bug#13408).
1623 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1624 Move handlers here from emacs.c; they were out of place.

1676 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1678 Avoid unnecessary byte position calculation for the gap movement.
1679 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1694 switches from 'signal' to 'pthread_sigmask', which is safer in
1695 multithreaded applications.

1697 which has already arranged for that.
1698 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

1711 predicate, which is how it's really used now. Adjust comment.
1712 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1713 * buffer.c (buffer_slot_type_mismatch): Remove.

1719 right-fringe-width, scroll-bar-width and buffer-display-count.
1720 Use Qstringp for default-directory, buffer-file-name,
1721 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1722 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

1771 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1772 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1773 digits for buffer positions, before misalignment starts.
1774 Display "0" for integer "object" field.
1775 (dump_glyph_row): Adapt the header line to changes in dump_glyph.

1868 file's SELinux context or ACLs successfully set, nil otherwise.
1870 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1872 * w32proc.c (reader_thread): Avoid passing NULL handles to
1873 SetEvent and WaitForSingleObject.
1875 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1877 Port EXTERNALLY_VISIBLE to Clang 3.2.
1878 * conf_post.h (__has_attribute): New macro.
1879 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1881 2012-12-27 Glenn Morris <rgm@gnu.org>
1883 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1884 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1886 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1888 * fileio.c (file_name_as_directory, directory_file_name):
1889 Accept an additional argument MULTIBYTE to indicate whether the input C
1890 came from a multibyte or a unibyte Lisp string; all callers
1891 adjusted. Don't assume the input string is always multibyte.
1893 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1894 don't ENCODE_FILE them, and return a unibyte string if the input
1896 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1897 don't assume the input strings will always be multibyte. If the
1898 input strings are multibyte, decode strings obtained from C
1901 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1903 * lisp.h (toplevel): Add two notices to the comment about
1904 defining a new Lisp data type.
1905 * print.c (print_object): If Lisp_Save_Value object's pointer
1906 is the address of a memory area containing Lisp_Objects, try
1908 * alloc.c (valid_lisp_object_p): Adjust comment.
1910 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1912 * keyboard.c (record_asynch_buffer_change): Initialize an event
1913 only if it's really needed.
1914 * frame.h (enum output_method): Remove output_mac member since
1915 it's a leftover from the deleted code.
1916 * frame.c (Fframep): Adjust user here ...
1917 * terminal.c (Fterminal_live_p): ... and here.
1918 * coding.c (Qmac): Now here because it's only used to denote
1919 end-of-line encoding type.
1920 (syms_of_coding): DEFSYM it.
1921 * frame.h (Qmac): Remove duplicated declaration.
1923 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1925 * window.c (select_window_1): Now static, since it's used only here.
1927 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1929 * window.c (window_body_cols): Subtract display margins from the
1930 window body width on TTYs as well. See
1931 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1932 for the original report.
1934 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1936 * xdisp.c (redisplay_window): Remove inner local variable
1937 because the outer shadowed one has the same meaning.
1938 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1940 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1941 (xg_create_tool_bar): Adjust users.
1943 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1945 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1946 * buffer.c (Fget_buffer_create): Use it to set compact field of
1947 struct buffer_text to avoid accessing an uninitialized value
1948 when compact_buffer is called for the first time.
1949 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1950 (Fset_buffer_modified_p): Use buffer_window_count to check
1951 whether the buffer is displayed in some window.
1952 * xdisp.c (message_dolog): Likewise.
1954 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1956 * w32.c (acl_set_file): If setting the file security descriptor
1957 fails, and the new DACL is identical to the existing one, silently
1958 return success. This fixes problems for users backing up their
1959 own files without having the necessary privileges for setting
1960 security descriptors.
1962 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1964 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1965 after WaitForSingleObject returns normally. This expedites reader
1966 thread shutdown when delete_child triggers it.
1967 (reap_subprocess): More accurate commentary for why we call
1968 delete_child only when cp->fd is negative.
1970 * w32.c (sys_close): Do not call delete_child on a subprocess
1971 whose handle is not yet closed. Instead, set its file descriptor
1972 to a negative value, so that reap_subprocess will call
1973 delete_child on that subprocess when its SIGCHLD arrives.
1974 This avoids closing handles used for communications between sys_select
1975 and reader_thread, which doesn't give sys_select a chance to
1976 notice that the process exited and invoke the SIGCHLD handler for
1979 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1981 * nsfns.m (Fns_do_applescript): Run event loop until script has
1982 been executed (Bug#12969).
1983 (ns_run_ascript): Chech as_script for nil, set to nil after
1986 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1988 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1990 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1992 * w32term.c (w32fullscreen_hook): New function.
1993 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1995 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1997 * fileio.c (Finsert_file_contents): Doc fix.
1999 * w32proc.c (new_child, delete_child, find_child_pid): For a
2000 subprocess, consider its slot being in use as long as its process
2001 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2002 slot when a new process is started immediately after killing
2003 another one, without waiting enough time for the first process to
2004 be reaped and resources allocated for it be orderly freed.
2006 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2008 2012-12-21 Chong Yidong <cyd@gnu.org>
2010 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2012 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2014 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2016 * w32.c (get_name_and_id): Always pass NULL as the first argument
2017 of lookup_account_sid. Avoids crashes with UNC file names that
2018 refer to DFS domains, not to specific machine names. (Bug#12621)
2019 Remove now unused argument FNAME; all callers changed.
2020 (get_file_owner_and_group): Remove now unused argument FNAME; all
2023 2012-12-21 Chong Yidong <cyd@gnu.org>
2025 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2026 error for invalid chars, don't check for a nil return value.
2028 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2030 Avoid calls to CHAR_TO_BYTE if byte position is known.
2031 * editfns.c (make_buffer_string_both): Use move_gap_both.
2032 (Fbuffer_string): Use make_buffer_string_both.
2033 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2035 (buf_bytepos_to_charpos): Likewise.
2036 (charpos_to_bytepos): Remove.
2037 * fileio.c (Finsert_file_contents): Use move_gap_both.
2038 * search.c (Freplace_match): Likewise.
2039 * process.c (process_send_region): Likewise. Use convenient
2040 names for byte positions.
2041 * lisp.h (charpos_to_bytepos): Remove prototype.
2042 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2043 * insdel.c (move_gap): Likewise.
2045 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2047 * xdisp.c (redisplay_internal): Remove now-unused local.
2049 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2051 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2052 (redisplay_internal): Don't bother selecting the frame to get the
2053 proper value of frame-local variables (bug#13225).
2055 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2057 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2058 Rename 4th argument since it may be buffer or string. Adjust comment.
2059 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2061 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2063 * coding.c (Fdetect_coding_region): Do not check start and end with
2064 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2065 (code_convert_region): Likewise.
2067 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2069 * w32.c (acl_get_file, acl_set_file): Run the file name through
2070 map_w32_filename, and resolve any symlinks in the file name, like
2072 (acl_set_file): Call revert_to_self, if any privileges were
2075 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2077 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2078 ($(BLD)/w32.$(O)): Update dependencies.
2080 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2082 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2083 propagate redisplay's scrolling (if any) to the right window.
2084 (redisplay_internal): Use ensure_selected_frame.
2085 (display_mode_lines): Complete last fix.
2086 * window.c (select_window_1): New func, extracted from select_window.
2087 (select_window): Use it.
2088 * window.h (select_window_1): Declare.
2090 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2092 Emulate Posix ACL APIs on MS-Windows.
2093 * w32.c: Include sddl.h and sys/acl.h.
2094 (SDDL_REVISION_1): Define if not already defined.
2095 (g_b_init_get_security_descriptor_dacl)
2096 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2097 (g_b_init_is_valid_security_descriptor)
2098 (g_b_init_set_file_security): New static flags.

2110 (acl_free, acl_get_file, acl_set_file): New functions.
2112 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2114 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2116 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2117 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2118 for some of that bug's symptoms can now cause Emacs to abort.
2119 Remove the workaround.
2120 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2121 The bug that caused SIGCHLD to get lost has been fixed, and the
2122 workaround for it can now cause Emacs to abort.
2124 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2126 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2127 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2128 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2130 2012-12-16 Romain Francoise <romain@orebokech.com>
2132 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2133 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2134 and copy ACL entries of file in addition to SELinux context if set.
2135 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2137 * Makefile.in (LIBACL_LIBS): New macro.
2140 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2142 * fileio.c (internal_delete_file): Use bool for boolean.
2144 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2146 Fix bug #13079 on MS-Windows with temp files not being deleted.

2149 (register_child): First argument is now pid_t.
2150 (record_infile, record_pending_deletion): New prototypes.
2152 * w32proc.c (new_child): Initialize input_file and
2153 pending_deletion members of the child.
2154 (delete_child): Delete the child's temporary input file, if any,
2155 that is pending deletion.
2156 (register_child): First argument is now pid_t.
2157 (record_infile, record_pending_deletion): New functions.
2158 (reap_subprocess): Fix a typo in DebPrint string.
2159 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2161 * fileio.c (internal_delete_file): Return an int again: non-zero
2162 if delete-file succeeds, zero otherwise.
2164 * lisp.h (internal_delete_file): Adjust prototype.
2166 * callproc.c (Fcall_process): Don't overwrite infile with result
2168 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2169 asynchronous subprocess, record the name of the input file name,
2171 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2172 delete the file, record it as pending deletion when the subprocess
2175 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2177 * editfns.c [HAVE_PWD_H]: Include grp.h.
2179 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2181 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2183 Fix permissions bugs with setgid directories etc. (Bug#13125)
2184 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2185 to mark it as a placeholder. The old value was often wrong.
2186 The only user of this attribute has been changed to use
2187 file-ownership-preserved-p instead, with its new group arg.
2188 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2190 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
2192 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

2195 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2197 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2198 try to get accurate owner and group information from NT file
2199 security APIs. This is to make most callers of 'stat' and
2200 'lstat', which don't need that information, much faster.
2202 * dired.c (Ffile_attributes) [WINDOWSNT]:
2203 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2204 owner and group information from 'lstat'.
2206 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2208 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2209 as that confuses set-auto-coding, so insist on the head-read
2210 returning the full 1024 bytes. Let lseek compute the tail offset;
2211 less work for us. Do not ignore I/O errors when reading the tail.
2213 * xdisp.c: Minor style fixes.
2214 (init_iterator): Hoist assignment out of if-expression.
2215 (markpos_of_region): Callers now test for sign, not for -1.
2217 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2219 Minor redisplay optimization when the region length is zero.
2220 * xdisp.c (markpos_of_region): New function.
2221 (init_iterator): Do not highlight the region of zero length.
2222 (redisplay_window): Check whether the region is of non-zero length.
2223 (try_cursor_movement): Allow if the region length is zero.
2224 (try_window_reusing_current_matrix, try_window_id): Likewise.
2226 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2228 * search.c (search_buffer): Check the inverse translations of each
2229 character in pattern when the buffer being searched is unibyte.
2232 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2234 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2235 files, fixing a regression from 24.2.
2236 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2238 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2240 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2241 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2242 Remove unnecessary S_ISLNK test, as (contra the comments) this
2243 function can't copy symlinks. Improve quality of error message
2244 when attempting to copy files that are neither regular files nor
2247 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2249 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

2251 * window.c (Frecenter):
2252 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2253 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2255 2012-12-12 Daniel Colascione <dancol@dancol.org>
2257 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2258 the dumped Emacs is not a sparse file, greatly improving Cygwin
2259 "make bootstrap" performance.
2261 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2263 * inotify.c (inotify_callback): Generate an Emacs event for every
2264 incoming inotify event.
2266 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2268 * xdisp.c (handle_face_prop): Fix logic of computing
2269 it->start_of_box_run_p.
2270 (append_space_for_newline): If the glyph row is R2L, reset the
2271 iterator's end_of_box_run_p flag before prepending the space glyph.
2272 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2273 iterator's start_of_box_run_p flag before prepending the stretch.
2274 (append_glyph, produce_image_glyph, append_composite_glyph)
2275 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2276 left_box_line_p and right_box_line_p flags of the glyph for R2L
2277 glyph rows. (Bug#13011)
2279 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2281 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2282 if changed buffer is not shown in a window.
2283 * insdel.c (prepare_to_modify_buffer): Likewise.
2284 * window.c (replace_buffer_in_windows_safely): Do nothing
2285 if buffer is not shown in a window.
2286 (Fforce_window_update): Likewise if string or buffer argument
2289 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2291 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2292 encoded_file_name, which is what it is.
2294 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2296 Consistently use marker_position and marker_byte_position.
2297 * fringe.c (Ffringe_bitmaps_at_pos):
2298 * indent.c (Fvertical_motion):
2299 * insdel.c (prepare_to_modify_buffer):
2300 * keyboard.c (make_lispy_position):

2303 (Fset_window_configuration):
2304 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
2305 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
2306 Replace direct access to marker fields with calls
2307 to marker_position and/or marker_byte_position.
2309 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
2311 * makefile.w32-in (SIG2STR_H): New macro.
2312 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
2313 ($(BLD)/w32notify.$(O)): Update dependencies.
2315 2012-12-10 Daniel Colascione <dancol@dancol.org>
2317 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
2318 Windows file notification functionality unless WINDOWSNT.
2320 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
2323 * w32fns.c (cache_system_info): Initialize the global hinst
2324 variable here so various initialization calls DTRT.
2326 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2327 (hinst): Remove unneeded extern declaration.
2328 (_start): Remove initialization of above variables; remove
2329 initialization of hinst, as cache_system_info now does that.
2331 * emacs.c (main): Call cache_system_info early in startup; we
2332 previously weren't calling it in Cygwin builds.
2334 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
2335 Teach the autoconf build system how to compile a Windows resource file
2336 and link it to Emacs.

2473 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2475 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

2477 * dbusbind.c (Fdbus_init_bus):
2479 * xterm.c (x_term_init):

2490 no longer needed here.
2491 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

2493 (set_time_zone_rule): Maintain the TZ=value string separately.
2494 (syms_of_editfns): Don't initialize initial_tz;
2495 init_editfns now does it.
2496 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2497 * lisp.h (xputenv): New decl.
2499 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

2515 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2516 Remove USG and vlimit methods; no longer used these days.
2517 Add #error catchall just in case.
2519 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2520 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2521 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2522 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.

2543 This will cause a production Emacs to dump core instead of
2546 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2548 * frame.c (make_frame): Do not set window's buffer to t.
2549 * window.c (Fsplit_window_internal): Likewise. Previously it was
2550 used to indicate that the window is being set up. Now we use
2551 set_window_buffer for all new windows, so the condition in ...
2552 (Fset_window_buffer): ... is always true and can be removed.
2554 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2556 Convenient macro to check whether the buffer is hidden.
2557 * buffer.h (BUFFER_HIDDEN_P): New macro.

2559 * buffer.c (candidate_buffer): New function.
2560 (Fother_buffer, other_buffer_safely): Use it.
2562 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2564 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG

2570 * frame.h (x_char_width, x_char_height): Remove prototypes.

2584 * callproc.c, process.h (record_kill_process):
2585 New function, containing part of the old call_process_kill.
2586 (call_process_kill): Use it.
2587 This does not change call_process_kill's behavior.
2588 * process.c (Fdelete_process): Use record_kill_process to fix a
2589 race condition that could cause Emacs to lose track of a child.
2591 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2593 Avoid code duplication between prev_frame and next_frame.
2594 * frame.c (candidate_frame): New function. Add comment.
2595 (prev_frame, next_frame): Use it. Adjust comment.
2597 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2599 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2600 fails, signal an error instead of continuing with an empty
2602 Encode expanded temp file pattern before passing it to mkstemp or
2605 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2606 Encode the file name before passing it to dostounix_filename, in
2607 case it will downcase it (under w32-downcase-file-names).
2610 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2612 Minor call-process cleanups.
2613 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2614 at the same time as other platforms, to simplify analysis.
2615 No need for fd0_volatile since we have synch_process_fd.
2616 Avoid needless emacs_close; arg is always negative.
2618 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2620 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

2625 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2626 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2627 and mouse_face_hidden members to a bitfields.
2628 * frame.h (struct frame): Remove set-but-not-used space_width member.
2629 (FRAME_SPACE_WIDTH): Remove.
2630 * nsterm.m, w32term.c, xterm.c: Adjust users.
2631 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2632 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2633 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2634 members to a bitfields.
2636 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2638 Don't let call-process be a zombie factory (Bug#12980).
2639 Fixing this bug required some cleanup of the signal-handling code.
2640 As a side effect, this change also fixes a longstanding rare race
2641 condition whereby Emacs could mistakenly kill unrelated processes,
2642 and it fixes a bug where a second C-g does not kill a recalcitrant
2643 synchronous process in GNU/Linux and similar platforms.
2644 The patch should also fix the last vestiges of Bug#9488,
2645 a bug which has mostly been fixed on the trunk by other changes.
2646 * callproc.c, process.h (synch_process_alive, synch_process_death)
2647 (synch_process_termsig, sync_process_retcode):
2648 Remove. All uses removed, to simplify analysis and so that
2649 less consing is done inside critical sections.
2650 * callproc.c (call_process_exited): Remove. All uses replaced
2651 with !synch_process_pid.
2652 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2653 These take the role of what used to be in unwind-protect arg.
2655 (block_child_signal, unblock_child_signal):
2656 New functions, to avoid races that could kill innocent-victim processes.
2657 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2658 (call_process_kill): Record killed processes as deleted, so that
2659 zombies do not clutter up the system. Do this inside a critical
2660 section, to avoid a race that would allow the clutter.
2661 (call_process_cleanup): Fix code so that the second C-g works again
2662 on common platforms such as GNU/Linux.
2663 (Fcall_process): Create the child process in a critical section,
2664 to fix a race condition. If creating an asynchronous process,
2665 record it as deleted so that zombies do not clutter up the system.
2666 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2667 light of these changes. Omit unnecessary call to emacs_close
2668 before failure, as the unwind-protect code does that.
2669 * callproc.c (call_process_cleanup):
2670 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2671 * process.c (record_deleted_pid): New function, containing
2672 code refactored out of Fdelete_process.
2673 (Fdelete_process): Use it.
2674 (process_status_retrieved): Remove. All callers changed to use
2675 child_status_change.
2676 (record_child_status_change): Remove, folding its contents into ...
2677 (handle_child_signal): ... this signal handler. Now, this
2678 function is purely a handler for SIGCHLD, and is not called after
2679 a synchronous waitpid returns; the synchronous code is moved to
2680 wait_for_termination. There is no need to worry about reaping
2681 more than one child now.
2682 * sysdep.c (get_child_status, child_status_changed): New functions.
2683 (wait_for_termination): Now takes int * status and bool
2684 interruptible arguments, too. Do not record child status change;
2685 that's now the caller's responsibility. All callers changed.
2686 Reimplement in terms of get_child_status.
2687 (wait_for_termination_1, interruptible_wait_for_termination):
2688 Remove. All callers changed to use wait_for_termination.
2689 * syswait.h: Include <stdbool.h>, for bool.
2690 (record_child_status_change, interruptible_wait_for_termination):
2692 (record_deleted_pid, child_status_changed): New decls.
2693 (wait_for_termination): Adjust to API changes noted above.
2695 * bytecode.c, lisp.h (Qbytecode): Remove.
2696 No longer needed after 2012-11-20 interactive-p changes.
2698 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2700 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2701 the scroll margin, move point outside the margin. (Bug#13055)
2703 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2705 * gtkutil.c (my_log_handler): New function.
2706 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2708 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2710 * lisp.h (modify_region): Rename to...
2711 (modify_region_1): ...new prototype.
2712 * textprop.c (modify_region): Now static. Adjust users.
2713 * insdel.c (modify_region): Rename to...
2714 (modify_region_1): ...new function to work with current buffer.
2715 Adjust comment and users. Use true and false for booleans.
2717 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2719 * alloc.c (free_save_value): New function.
2720 (safe_alloca_unwind): Use it.
2721 * lisp.h (free_save_value): New prototype.
2722 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2724 (save_excursion_restore): Adjust to match saved data structure.
2725 Use free_save_value to offload some work from GC. Drop obsolete
2728 2012-12-03 Chong Yidong <cyd@gnu.org>
2730 * fileio.c (Vauto_save_list_file_name): Doc fix.
2732 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2734 * w32fns.c: Remove prototype of atof.
2735 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2737 (file_dialog_callback): Make it UINT_PTR.
2739 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2742 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2743 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2746 2012-12-03 Glenn Morris <rgm@gnu.org>
2748 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2750 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2752 Fix xpalloc confusion after memory is exhausted.
2753 * alloc.c (xpalloc): Comment fix.
2754 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2755 and signals an error, do not clear charset_table_size, as
2756 charset_table is still valid.
2757 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2759 Use execve to avoid need to munge environ (Bug#13054).
2760 * callproc.c (Fcall_process):
2761 * process.c (create_process):
2762 Don't save and restore environ; no longer needed.
2763 * callproc.c (child_setup):
2764 Use execve, not execvp, to preserve environ.
2766 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2768 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2770 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2772 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2773 display for sliced images (Bug#10500).
2775 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2777 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2779 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2780 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2782 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2784 * xdisp.c (window_outdated): Remove eassert since it hits
2785 some suspicious corner cases (see Bug#13007 and Bug#13012).
2786 (mode_line_update_needed): New function.
2787 (redisplay_internal, redisplay_window): Use it.

2790 (redisplay_internal): Move comment about buffer_shared...
2791 (buffer_shared_and_changed): ...near to its real use.
2793 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2795 * callproc.c (Fcall_process): Don't misreport vfork failure.
2797 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2799 * callproc.c (Fcall_process): Fix vfork portability problems.
2800 Do not assume that fd[0], count, filefd, and save_environ survive
2801 vfork. Fix bug whereby wrong errno value could be reported for
2802 pipe failure. Some minor cleanups, too, as follows. Move buf and
2803 bufsize to the context where they're needed. Change new_argv to
2804 be of type char **, as this is more convenient and avoids casts.
2805 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2806 Now local constants, not macros.
2808 2012-11-18 Kenichi Handa <handa@gnu.org>
2810 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2811 for the variable "f".
2813 2012-11-13 Kenichi Handa <handa@gnu.org>
2815 * font.c (font_unparse_xlfd): Exclude special characters from the
2816 generating XLFD name.
2818 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2820 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2821 * dired.c (stat_uname, stat_gname):
2822 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2824 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2826 Assume EAGAIN and EINTR are defined.
2828 * fileio.c (Fcopy_file): Assume EISDIR is defined.
2829 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
2830 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
2831 * lread.c (readbyte_from_file): Assume EINTR is defined.
2832 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2833 Assume EIO and EAGAIN are defined.
2834 * unexcoff.c (write_segment): Assume EFAULT is defined.
2836 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2838 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2841 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2842 highlighting on the frame was cleared. Prevents assertion
2843 violations when repeatedly clicking on the "Top" link of the
2844 "bread-crumbs" in Info buffers.
2846 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2848 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2850 2012-11-24 Ken Brown <kbrown@cornell.edu>
2852 * keyboard.c (HAVE_MOUSE):
2853 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2854 were always defined.
2856 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2858 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2859 between bpos_covered and bpos_max. This fixes cursor display when
2860 several display strings follow each other.
2862 * .gdbinit (pgx): If the glyph's object is a string, display the
2863 pointer to string data, rather than the value of the string object
2864 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2866 * indent.c (Fvertical_motion): If the starting position is covered
2867 by a display string, return to one position before that, to avoid
2868 overshooting it inside move_it_to. (Bug#12930)
2870 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2872 * frame.h (struct frame): Remove display_preempted member
2873 since all users are dead long ago.
2874 * nsterm.h (struct x_output): Use the only dummy member.
2875 * w32menu.c (pending_menu_activation): Remove since not
2877 (set_frame_menubar): Adjust user.
2878 * w32term.h (struct x_output): Drop outdated #if 0 code.
2879 (struct w32_output): Use bitfields for explicit_parent,
2880 asked_for_visible and menubar_active members.
2881 Drop unused pending_menu_activation member.
2882 * xterm.h (struct x_output): Drop outdated #if 0 code.
2883 Use bitfields for explicit_parent, asked_for_visible,
2884 has_been_visible and net_wm_state_hidden_seen members.
2886 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2888 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2889 of a literal "/". (Bug#12955)
2890 (gl-stamp): Invoke fc.exe directly, not through cmd.
2892 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2894 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2895 * dired.c: Assume HAVE_DIRENT_H.
2896 (NAMLEN): Remove, replacing with ...
2897 (dirent_namelen): New function. All uses changed. Use the GNU macro
2898 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2899 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2900 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2901 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2903 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2904 * ndir.h: Rename to ../nt/inc/dirent.h.
2905 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2906 Do not include <dirent.h>; no longer needed.
2907 * w32.c: Include <dirent.h> rather than "ndir.h".
2909 2012-11-23 Chong Yidong <cyd@gnu.org>
2911 * xftfont.c (xftfont_open): Remove duplicate assignment.
2913 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2915 * alloc.c (Fgarbage_collect): Unblock input after clearing
2916 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2917 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2918 * msdos.c (IT_frame_up_to_date): Use it here...
2919 * w32term.c (w32_frame_up_to_date): ...here...
2920 * xterm.c (XTframe_up_to_date): ...and here...
2921 * nsterm.m (ns_frame_up_to_date): ...but not here.
2922 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2924 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2925 Do not check whether GC is in progress.
2927 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2929 * xdisp.c (window_buffer_changed): New function.
2930 (update_menu_bar, update_tool_bar): Use it to
2931 simplify large 'if' statements.
2932 (redisplay_internal): Generalize commonly used
2933 'tail' and 'frame' local variables.
2935 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2937 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2938 with Windows system header.
2940 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2942 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2943 * alloc.c: Assume unistd.h exists.
2944 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2945 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2946 (getwd) [USG]: Remove; no longer needed.
2947 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2948 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2949 * w32.h (getcwd): Remove decl.
2951 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2953 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2954 Make it set selected_window as well.
2955 (update_tool_bar): Use it.
2957 2012-11-21 Ken Brown <kbrown@cornell.edu>
2959 * emacs.c (main): Set the G_SLICE environment variable for all
2960 Cygwin builds, not just GTK builds. See
2961 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2963 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2965 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2966 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2967 Define for the MSVC compiler.
2969 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2971 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2972 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2973 dostounix_filename. Prevents crashes down the road, because
2974 dostounix_filename assumes it gets a unibyte string.
2975 Reported by Michel de Ruiter <michel@sentient.nl>, see
2976 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2978 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

2982 * lread.c (init_obarray): Set `function' fields to Qnil.
2983 * eval.c (Fcommandp): Ignore Qunbound.
2984 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2985 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2986 Test NILP rather than Qunbound.
2987 (Ffmakunbound): Set to Qnil.
2988 (Fsymbol_function): Never signal an error.
2989 (Finteractive_form): Ignore Qunbound.
2991 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2993 * eval.c (interactive_p): Remove no-longer-used decl.
2995 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2997 * xdisp.c (buffer_shared): Adjust comment.
2998 (buffer_shared_and_changed): New function.
2999 (prepare_menu_bars, redisplay_internal): Use it to
3000 decide whether all windows or frames should be updated.
3001 (window_outdated): New function.
3002 (text_outside_line_unchanged_p, redisplay_window): Use it.
3003 (redisplay_internal): Likewise. Fix indentation.
3005 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3007 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3008 (syms_of_eval): Remove corresponding defsubr.
3009 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3011 2012-11-19 Daniel Colascione <dancol@dancol.org>
3013 * w32fns.c (Fx_file_dialog):
3014 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3015 cygwin_convert_file_name*.
3017 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3018 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3020 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3022 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3024 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3026 * w32select.c: Include w32common.h before w32term.h, so that
3027 windows.h gets included before w32term.h uses some of its
3028 features, see below.
3030 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3032 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3034 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3036 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3038 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3039 (ns_select): Return at once if events are held (Bug#12834).
3041 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3043 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3044 Needed following 2012-10-20 change. (Bug#12902)
3046 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3048 * w32proc.c (waitpid): Remove unused label get_result.
3050 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3052 * makefile.w32-in (SYSWAIT_H): New macro.
3053 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3054 ($(BLD)/sysdep.$(O)): Update dependencies.
3056 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3058 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3059 * callproc.c (relocate_fd): Assume F_DUPFD.
3060 * emacs.c, term.c (O_RDWR): Remove.
3061 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3062 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3063 * nsterm.m: Assume <fcntl.h> exists.
3064 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3065 (create_pty, Fmake_network_process, server_accept_connection)
3066 (wait_reading_process_output, init_process_emacs):
3068 (wait_reading_process_output): Put in a special case for WINDOWSNT
3069 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3070 It's not clear this is needed, but it's a more-conservative change.
3071 (create_process): Assume FD_CLOEXEC.
3072 (create_process, create_pty): Assume O_NOCTTY.
3073 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3074 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3075 Omit if not DOS_NT, since F_GETFL is not defined there.
3076 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3077 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3079 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3080 lack it, since gnulib guarantees this.
3081 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3083 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3085 * w32.c (faccessat): Pretend that directories have the execute bit
3086 set. Emacs expects that, e.g., in files.el:cd-absolute.
3088 * w32proc.c (create_child): Don't clip the PID of the child
3089 process to fit into an Emacs integer, as this is no longer a
3091 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3092 reaping only the process specified by PID argument, if that is
3093 positive. Use PID instead of dead_child to know which process to
3094 reap. Wait for the child to die only if WNOHANG is not in
3096 (sys_select): Don't set dead_child.
3098 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3099 as it is no longer needed.
3101 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3103 (record_child_status_change): Remove the setting of
3104 record_at_most_one_child for the !WNOHANG case.
3106 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3108 Fix problems in ns port found by static checking.
3109 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3110 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3111 not to process group.
3112 (ns_select): Use emacs_write, not write, as that's more robust
3113 in the presence of signals.
3114 (fd_handler:): Check for read errors.
3116 2012-11-16 Glenn Morris <rgm@gnu.org>
3118 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3120 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3122 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3124 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3126 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3127 use the same value of thread handle.
3128 (start_timer_thread): If the timer thread exited (due to error),
3129 clean up by closing the two handles it used. Duplicate the caller
3130 thread's handle here, so it gets duplicated only once, when
3131 launching the timer thread. Set priority of the timer thread, not
3133 (getitimer): Don't duplicate the caller thread's handle here.
3136 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3138 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3141 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3143 Remove no-longer-used pty_max_bytes variable.
3144 * process.c (pty_max_bytes): Remove; unused.
3145 (send_process): Do not set it.
3147 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3149 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3150 Update dependencies.
3152 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3154 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3155 This follows up on the 2012-09-29 patch that removed indirection
3156 for the 'function' field. Reported by Sergey Vinokurov in
3157 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3159 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3161 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3162 different name, as the MS runtime does not have such a function,
3163 and probably never will.) All callers changed. Ignore DIRFD
3164 value if PATH is an absolute file name, to match Posix spec
3165 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3168 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3170 * xdisp.c (echo_area_display, redisplay_internal):
3171 Omit redundant check whether frame_garbaged is set.
3173 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3175 Use faccessat, not access, when checking file permissions (Bug#12632).
3176 This fixes a bug that has been present in Emacs since its creation.
3177 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3178 which must set some sort of record. (Torek's bug report was against
3179 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3180 same common flaw.) See Torek's Usenet posting
3181 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3182 Posted: Fri Apr 8 14:18:56 1983.
3183 * Makefile.in (LIB_EACCESS): New macro.
3185 * callproc.c (init_callproc):
3186 * charset.c (init_charset):
3187 * fileio.c (check_existing, check_executable, check_writable)
3189 * lread.c (openp, load_path_check):
3190 * process.c (allocate_pty):
3192 Use effective UID when checking permissions, not real UID.
3193 * callproc.c (init_callproc):
3194 * charset.c (init_charset):
3195 * lread.c (load_path_check, init_lread):
3196 Test whether directories are accessible, not merely whether they exist.
3197 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3198 * fileio.c (check_existing, check_executable, check_writable)
3200 Use symbolic names instead of integers for the flags, as they're
3202 (check_writable): New arg AMODE. All uses changed.
3203 Set errno on failure.
3204 (Ffile_readable_p): Use faccessat, not stat + open + close.
3205 (Ffile_writable_p): No need to call check_existing + check_writable.
3206 Just call check_writable and then look at errno. This saves a syscall.
3207 dir should never be nil; replace an unnecessary runtime check
3208 with an eassert. When checking the parent directory of a nonexistent
3209 file, check that the directory is searchable as well as writable, as
3210 we can't create files in unsearchable directories.
3211 (file_directory_p): New function, which uses 'stat' on most platforms
3212 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3213 (Ffile_directory_p, Fset_file_times): Use it.
3214 (file_accessible_directory_p): New function, which uses a single
3215 syscall for efficiency.
3216 (Ffile_accessible_directory_p): Use it.
3217 * xrdb.c (file_p): Use file_directory_p.
3218 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3219 * lread.c (openp): When opening a file, use fstat rather than
3220 stat, as that avoids a permissions race. When not opening a file,
3221 use file_directory_p rather than stat.
3222 (dir_warning): First arg is now a usage string, not a format.
3223 Use errno. All uses changed.
3224 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3225 that merely introduced a race.
3226 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3227 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3228 and similarly for the other O_* flags.
3229 * w32.c (sys_faccessat): Rename from sys_access and switch to
3230 faccessat's API. All uses changed.
3231 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3232 (magic_db): Rename from magic_file_p.
3233 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3234 char *, so that we don't have to test for file existence
3235 separately from opening the file for reading. This removes a race
3236 fixes a permission-checking problem, and simplifies the code.
3238 (file_p): Remove; no longer needed.
3240 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3242 Omit glyphs initialization at startup.
3243 * dispnew.c (glyphs_initialized_initially_p): Remove.
3244 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3245 (Fredraw_frame): Move actual code from here...
3246 (redraw_frame): ...to here. Add eassert. Adjust comment.
3247 (Fredraw_display): Use redraw_frame.
3248 * xdisp.c (clear_garbaged_frames): Likewise.
3250 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3252 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3253 passed to pint2str and pint2hrstr to be at most the size of the
3254 frame's decode_mode_spec_buffer. This avoids crashes with very
3255 large values of FIELD_WIDTH argument to decode_mode_spec.
3258 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3260 Fix a race with verify-visited-file-modtime (Bug#12863).
3261 Since at least 1991 Emacs has ignored an mtime difference of no
3262 more than one second, but my guess is that this was to work around
3263 file system bugs that were fixed long ago. Since the race is
3264 causing problems now, let's remove that code.
3265 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3266 whose time stamp is off by no more than a second. Insist that the
3267 file time stamps match exactly.
3269 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3271 * frame.h (struct frame): Convert external_tool_bar member to
3272 1-bit unsigned bitfield.

3290 (x_window_to_menu_bar): Likewise.
3291 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3293 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3295 * data.c (Qdefalias_fset_function): Now static.
3297 Another tweak to vectorlike_header change.

3300 (next_in_free_list, set_next_in_free_list):
3301 New functions, which respect C's aliasing rules better.
3303 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3305 * window.c (list4i): Rename from 'quad'. All uses changed.
3306 Needed because <sys/types.h> defines 'quad' on Solaris 10.

3320 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3322 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3323 amount when the scroll margins are too large. When scrolling
3324 backwards in the buffer, give up if cannot reach point or the
3325 scroll margin within a reasonable number of screen lines.
3326 Fixes point position in window under scroll-up/down-aggressively when
3327 point is positioned many lines beyond the window top/bottom.
3330 * ralloc.c (relinquish): If real_morecore fails to return memory
3331 to the system, don't crash; instead, leave the last heap
3332 unchanged and return. (Bug#12774)

3353 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3355 Fix recently introduced crash on MS-Windows (Bug#12839).
3356 * w32term.h (struct scroll_bar): Use convenient header.
3357 (SCROLL_BAR_VEC_SIZE): Remove.
3358 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3360 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3362 Tweak last vectorlike_header change.
3363 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3364 vectorlike object on the free list. This is introduced to avoid
3365 some (but not all) pointer casting and aliasing problems, see
3366 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3367 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3371 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3373 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3374 been removed, so remove them here also.
3376 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3378 * doc.c (Fdocumentation): Handle new property
3379 dynamic-docstring-function to replace the old ad-advice-info.
3381 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3383 * fns.c (Qeql, hashtest_eq): Now static.
3385 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3387 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3388 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3389 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3408 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3410 * image.c (xpm_make_color_table_h): Fix compiler error because
3411 make_hash_table changed.
3413 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3415 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3417 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3419 Use ad-hoc comparison function for the profiler's hash-tables.
3420 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3421 (make_log): Use them.
3422 (handle_profiler_signal): Don't inhibit quit any longer since we don't

3432 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3433 (hash_lookup, hash_remove_from_table): Move assertion checking of
3434 hashfn result here. Check hash-equality before calling cmpfn.

3436 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3437 (syms_of_fns): Initialize them.

3446 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3447 value of w32-scroll-lock-modifier is neither nil nor one of the
3448 known key modifiers. (Bug#12806)
3450 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3452 Shrink struct vectorlike_header to the only size field.
3453 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3455 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3456 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3457 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3458 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3459 information from the vector header. Adjust comment.
3460 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
3461 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header

3471 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3472 (Fmake_bool_vector): Likewise.

3474 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3475 (large_vectors): Change type to struct large_vector.
3476 (allocate_vector_from_block): Simplify.
3477 (PSEUDOVECTOR_NBYTES): Replace with...
3478 (vector_nbytes): ...new function. Adjust users.
3479 (sweep_vectors): Adjust processing of large vectors.
3480 (allocate_vectorlike): Likewise.
3481 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3482 Add easserts. Adjust XSETPVECTYPESIZE usage.
3483 (allocate_buffer): Use BUFFER_PVEC_INIT.
3484 (live_vector_p): Adjust to match large vector.
3485 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3486 * buffer.h (struct buffer): Add next member.
3487 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3489 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

3495 (xvecsize): New command.
3497 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3499 * keyboard.c (event_to_kboard): Do not dereference
3500 frame_or_window field of SELECTION_REQUEST_EVENT
3501 and SELECTION_CLEAR_EVENT events (Bug#12814).
3502 * xterm.h (struct selection_input_event): Adjust comment.
3504 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3506 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3507 such as Scroll Lock, if the respective keys are treated as
3508 function keys, not as modifiers. This avoids destroying non-ASCII
3509 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3511 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3513 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3515 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3517 Restore some duplicate definitions (Bug#12814).
3518 This undoes part of the 2012-11-03 changes. Some people build
3519 with plain -g rather than with -g3, and they need the duplicate
3520 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3521 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3522 Define as macros, as well as as enums or as constants.
3524 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3526 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3527 to keypad keys (Bug#12816).
3529 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3531 Minor adjustments of recently-changed frame functions.
3532 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3533 known to be a frame (we're in the FRAMEP branch).
3534 * lisp.h (Qframep): Remove decl. frame.h declares this.
3535 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3536 since they're meant for Lisp fixnum values.
3538 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3540 * window.c (Fwindow_combination_limit): Revert to the only
3541 required argument and adjust docstring as suggested in
3542 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3543 by Martin Rudalics <rudalics@gmx.at>.
3545 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3547 Widely used frame validity and checking functions.
3548 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3549 * frame.c (decode_live_frame, decode_any_frame): New functions.
3550 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3551 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3552 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3553 (Fframe_pointer_visible_p): Use decode_any_frame.

3555 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3556 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3557 (Fframe_focus): Likewise. Allow zero number of arguments.
3559 (frame_buffer_list, frame_buffer_predicate): Remove.
3560 * lisp.h (frame_buffer_predicate): Remove prototype.
3561 * buffer.c (Fother_buffer): Use decode_any_frame.
3562 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3563 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3564 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3565 (Fclose_font, Ffont_info): Use decode_live_frame.
3566 * fontset.c (check_fontset_name): Likewise.
3567 * terminal.c (Fframe_terminal): Likewise.
3568 * w32fns.c (check_x_frame): Likewise.
3569 * window.c (Fminibuffer_window, Fwindow_at)
3570 (Fcurrent_window_configuration): Likewise.
3571 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3572 Likewise. Allow zero number of arguments. Adjust docstring.
3573 * dispnew.c (Fredraw_frame): Likewise.
3574 * xfaces.c (frame_or_selected_frame): Remove.
3575 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3576 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3577 (Fframe_face_alist): Use decode_live_frame.
3578 * xfns.c (check_x_frame): Likewise.
3580 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3582 * window.c (quad): New function.
3583 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3584 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3585 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3586 (Fwindow_line_height): Use it.
3587 (Fwindow_fringes): Use list3.
3588 (Fwindow_scroll_bars): Use list4.
3589 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3590 (Fwindow_combination_limit): Allow zero number of arguments.
3592 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3594 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3596 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3597 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3598 file descriptor 2 for standard error. (Bug#12805)
3600 2012-11-05 Chong Yidong <cyd@gnu.org>
3602 * process.c (wait_reading_process_output): Revert previous change.
3604 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3606 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3607 This removes code that has been obsolete since around 1990.
3608 * callproc.c (Fcall_process):
3610 * process.c (create_process):
3611 * term.c (dissociate_if_controlling_tty):
3612 Assume setsid exists.
3613 * callproc.c (child_setup): Assume setpgid exists and behaves as
3614 per POSIX.1-1988 or later.
3615 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3616 * emacs.c (shut_down_emacs):
3617 * sysdep.c (sys_suspend, init_foreground_group):
3618 Assume getpgrp behaves as per POSIX.1-1998 or later.
3619 * msdos.c (setpgrp): Remove.
3620 (tcgetpgrp, setpgid, setsid): New functions.
3621 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3622 * term.c (no_controlling_tty): Remove; unused.
3623 * w32proc.c (setpgrp): Remove.
3624 (setsid, tcgetpgrp): New functions.
3626 Simplify by assuming __fpending.
3627 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3628 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3629 Do not assume that __fpending's result fits in int.
3631 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3633 Remove EMACS_OUTQSIZE+sleep hack.
3634 * dispnew.c (update_frame_1): Remove hack for terminals slower
3635 than 2400 bps, which throttled Emacs by having it sleep.
3636 This code hasn't worked since at least 2007, when the multi-tty stuff
3637 was added, and anyway those old terminals are long dead.
3638 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3639 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3641 Fix data-loss with --version (Bug#9574).
3642 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3643 as we can't assume that emacs_strerror is initialized, and strerror
3644 is good enough here.
3645 (main): Invoke atexit earlier, to catch earlier instances of
3646 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3648 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3650 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3651 (keyDown): Remap keypad keys to X11 virtual key codes.
3653 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3655 Fix data-loss with --batch (Bug#9574).
3656 * emacs.c: Include <close-stream.h>.
3657 (close_output_streams): New function.
3658 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3659 and handles errors appropriately.
3660 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3663 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3664 The symptom is a diagnostic "GLib-WARNING **: In call to
3665 g_spawn_sync(), exit status of a child process was requested but
3666 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3667 waitpid(), so exit status can't be returned." The diagnostic
3668 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3669 The real bug is a race condition between Emacs and glib: Emacs
3670 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3671 so that glib can't find it. Work around the bug by invoking
3672 waitpid only on subprocesses that Emacs itself creates.
3673 * process.c (create_process, record_child_status_change):
3674 Don't use special value -1 in pid field, as the caller now must
3675 know the pid rather than having the callee infer it.
3676 The inference was sometimes incorrect anyway, due to another race.
3677 (create_process): Set new 'alive' member if child is created.
3678 (process_status_retrieved): New function.
3679 (record_child_status_change): Use it.
3680 Accept negative 1st argument, which means to wait for the
3681 processes that Emacs already knows about. Move special-case code
3682 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3683 processes that have already been waited for, by testing and
3684 clearing new 'alive' member.
3685 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3686 now does this internally.
3687 (handle_child_signal): Let record_child_status_change do all
3688 the work, since we do not want to reap all exited child processes,
3689 only the child processes that Emacs itself created.
3690 * process.h (Lisp_Process): New boolean member 'alive'.
3692 Omit duplicate definitions no longer needed with gcc -g3.

3694 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3695 Define only as macros. There's no longer any need to also define
3696 these symbols as enums or as constants, since we now assume
3697 gcc -g3 when debugging.
3699 2012-11-03 Eli Zaretskii <eliz@gnu.org>

3727 2012-11-03 Chong Yidong <cyd@gnu.org>
3729 * buffer.c (cursor_type): Untabify docstring.
3731 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3733 * frame.h (struct frame): Drop can_have_scroll_bars member

3779 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3781 Remove pad from struct input_event.
3782 * termhooks.h (struct input_event): Remove padding field.
3784 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3785 member is never cons for a long time. Adjust comment.
3786 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3787 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3788 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3789 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3791 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3793 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3795 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3797 Fix crash when using Emacs as commit editor for git (Bug#12697).
3798 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3799 and it is configured in conf_post.h.
3800 (Fcall_process): Don't invoke both setsid and setpgid; the former
3801 is enough, if it exists.
3802 * callproc.c (Fcall_process, child_setup):
3803 * process.c (create_process): Use setpgid.
3804 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3806 * dispnew.c (init_display): Initialize the foreground group
3807 if we are running a tty display.
3808 * emacs.c (main): Do not worry about setpgrp; init_display does it now.

3816 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3818 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3820 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3822 * minibuf.c (read_minibuf): Restore current buffer since
3823 choose_minibuf_frame calling Fset_frame_selected_window may
3824 change it (Bug#12766).

3832 * font.c (Ffont_at): If WINDOW is specified and it is not
3833 displaying the current buffer, signal an error.
3835 2012-10-29 Daniel Colascione <dancol@dancol.org>
3837 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3838 In preparation for fixing bug#12739, move these functions from
3841 * coding.h, coding.c: ... to here, and compile them only when
3842 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3843 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3845 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3847 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3848 (timer_loop, getitimer, setitimer): Use it instead of

3860 of [last_appdefined_event data1].
3861 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3862 remove last_appdefined_event (Bug#12698).
3864 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3866 * frame.c (x_set_font): Catch internal error.
3868 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3870 Avoid overflow in w32 implementation of interval timers.
3871 When possible, for ITIMER_PROF count only times the main thread
3873 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3874 'volatile ULONGLONG' types. All the other data which was
3875 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3876 (GetThreadTimes_Proc): New typedef.
3877 (w32_get_timer_time): New function, returns a suitable time value
3879 (timer_loop): Enter critical section when accessing ULONGLONG
3880 values of the itimer_data struct, as these accesses are no longer
3881 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3882 Remove unused variable.
3883 (init_timers): Initialize s_pfn_Get_Thread_Times.
3884 (start_timer_thread): Don't assign itimer->caller_thread here.
3885 (getitimer): Assign itimer->caller_thread here.

3891 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3892 mouse movement events if the menu bar is active. This avoids
3893 producing a busy "hour-glass" cursor by Windows if the mouse
3894 pointer is positioned over a tooltip shown for some menu item.
3896 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3898 Don't assume process IDs fit in int.
3899 * emacs.c (shut_down_emacs) [!DOS_NT]:
3900 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3901 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3902 Use pid_t, not int, to store process IDs, as 'int'
3903 is not wide enough on a few platforms (e.g., AIX and IRIX).
3905 2012-10-23 Kenichi Handa <handa@gnu.org>
3907 The following change is to make face-font-rescale-alist work
3908 correctly for non-ASCII fonts.

3928 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3930 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

3933 * frame.c (Fmouse_position, Fmouse_pixel_position):
3934 * xdisp.c (produce_stretch_glyph):
3935 Declare local vars only when they're needed.
3936 This is clearer and avoids a warning on OpenBSD about unused vars.

3938 This is safer, and avoids OpenBSD warnings about unused vars.
3939 * keyboard.c (record_menu_key): Remove unnecessary decl.
3940 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3941 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3942 as our definition clashes with OpenBSD's.
3943 * xfaces.c (load_face_colors, check_lface_attrs)
3944 (get_lface_attributes_no_remap, get_lface_attributes)
3945 (lface_fully_specified_p, x_supports_face_attributes_p)
3946 (tty_supports_face_attributes_p, face_fontset, realize_face)
3947 (realize_x_face, realize_tty_face):
3948 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3949 merely Lisp_Object *. This is more informative and avoids
3950 a warning on OpenBSD about accessing beyond an object's size.
3952 2012-10-20 Chong Yidong <cyd@gnu.org>
3954 * lread.c (Fload): Doc fix (Bug#12592).

3980 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3981 (staticpro): If we run out of staticpro slots, die with an
3982 informative error instead of just calling emacs_abort.
3984 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3986 Fix two flaws reported by Dmitry Antipov.

4108 removed or renamed by some other process immediately after Emacs
4109 writes it but before Emacs stats it. Do not assume that stat (or

4185 Use bool for booleans.
4186 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
4187 as it's not a predicate. All uses changed. Omit unnecessary

4195 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
4197 * marker.c (cached_modiff): EMACS_INT, not int.
4199 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
4200 instead of having a wrong decl.

4238 (detect_input_pending_run_timers):
4239 * process.c (wait_reading_process_output):
4240 Use unsigned for counter where wraparound-on-overflow is desired,
4241 since unsigned is guaranteed to have that behavior and signed is not.
4242 (read_char): Use ptrdiff_t for string length.
4243 (get_input_pending): Remove first argument, since it was always
4244 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4245 and behave as if it had that value. Return new value of
4246 input_pending. All callers changed.
4247 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4248 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4250 * keymap.c (push_key_description): Omit last arg, which was always 1.
4251 All callers changed.
4253 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

4271 Don't include termopts.h.
4273 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4275 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4277 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4279 * commands.h (immediate_quit): Remove duplicate decl.
4281 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4283 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

4286 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4288 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4290 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4291 match what GetLastError returns. Explain why the function is
4294 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4295 'is_tooltip_frame', to avoid confusion with its global namesake.
4297 2012-10-08 Daniel Colascione <dancol@dancol.org>
4299 * xdisp.c (start_hourglass): Call w32_note_current_window when
4300 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4301 build that caused Emacs to display the hourglass cursor forever.
4303 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4304 which is broken under remote desktop, calculate the number of
4305 colors available for a display based on the display's number of
4306 planes and number of bits per pixel per plane. (bug#10397).
4308 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4310 * nsfont.m (Vfonts_in_cache): New variable.
4311 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4312 are used. Add cached fonts to Vfonts_in_cache.
4313 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4315 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4317 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4319 (FONT_H): Define after FRAME_H.
4320 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4321 Update dependencies.
4323 * w32term.c: Remove leftover declaration of keyboard_codepage.
4325 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4327 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4328 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4329 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4330 (GLOBAL_SOURCES): Add cygw32.c.

4333 ($(BLD)/w32console.$(O)):
4334 ($(BLD)/w32fns.$(O)):
4335 ($(BLD)/w32heap.$(O)):
4336 ($(BLD)/w32menu.$(O)):
4337 ($(BLD)/w32proc.$(O)): Add w32common.h.
4339 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4341 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4343 2012-10-08 Daniel Colascione <dancol@dancol.org>
4345 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4346 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4347 accidental message numbering hole. Change other messages to
4350 * w32select.h (HAVE_W32SELECT): Remove.
4352 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4353 w32common.h instead of w32heap.h.
4355 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4356 (get_allocation_unit, get_processor_type, get_w32_major_version)
4357 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4358 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4359 (OS_NT, os_subtype, cache_system_info): Move declarations to
4362 * w32heap.c: Include w32common.h.
4363 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4364 (w32_minor_version, w32_build_number, w32_subtype):
4365 Remove duplicate definitions.
4367 * w32fns.c: Include w32common.h; include w32heap.h only in
4370 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4371 Use `report_file_error' instead of `error' in order to better
4372 inform users of what went wrong. Increase NTGUI_UNICODE file
4373 dialog box file name length to 32k, the maximum allowed by the NT
4376 * w32common.h: New file.
4377 (ROUND_UP, ROUND_DOWN, get_page_size)
4378 (get_allocation_unit, get_processor_type, get_w32_major_version)
4379 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4380 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4381 (OS_NT, os_subtype, cache_system_info): Move here.
4383 * unexw32.c, unexcw.c: Include w32common.h.
4385 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4386 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4387 to call syms_of_w32select.
4389 * cygw32.h: Remove obsolete EXFUN declarations.
4391 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4393 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4394 of w32inevt.o from SOME_MACHINE_OBJECTS.
4396 2012-10-08 Daniel Colascione <dancol@dancol.org>
4398 * image.c: Permanent fix for JPEG compilation issue --- limit
4399 jpeglib `boolean' redefinition to Cygwin builds.
4401 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4403 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4405 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4408 2012-10-08 Daniel Colascione <dancol@dancol.org>
4410 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4411 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4412 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4413 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4414 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4415 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4416 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4417 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4418 now a supported configuration.
4420 * Makefile.in: consolidate image variables into LIBIMAGE; add
4421 W32_OBJ and W32_LIBS. Compile new files.
4424 (_DebPrint) declare tracing facility for W32 debugging. We need
4425 to unify tracing later.
4427 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4428 unconditional use of W32 Unicode functions. Cygwin runs only on
4429 100% Unicode operating systems.
4431 * cygw32.c: New file. Define Cygwin-specific facilities.
4432 (Fcygwin_convert_path_to_windows)
4433 (Fcygwin_convert_path_from_windows): New user functions for
4434 accessing Cygwin path-munging routines.
4436 * cygw32.h: New file.
4437 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4438 UTF-16LE strings temporarily inside non-Lisp-visible string
4441 (w32_strerror): Just what it says on the tin.
4443 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4444 also run for Cygwin; both systems have the same problem with using
4445 GUI facilities in a forked child. Also call syms_of_cygw32,
4446 syms_of_w32select in correct places.
4448 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4449 needs fork-then-exec for daemon launching.
4451 * font.h: Include frame.h.
4453 * image.c: Use the image library cache machinery only when we're
4454 compiling for native WINDOWSNT; Cygwin can use shared libraries
4455 like any other Unixlike system.
4457 * keyboard.c: Clarify a comment regarding the input loop.
4459 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4460 functions directly instead of trying to detect at runtime that our
4461 host operating system supports them. We make this change for two
4462 reasons: Cygwin lacks support for the multibyte character
4463 conversion functions used by the legacy menu code, and Cygwin
4464 never needs to rely on non-Unicode APIs.
4466 * unexw32.c (hinst): Declare extern.
4468 * w32.c: Change header order;
4469 (w32_strerror): Move to w32fns.c because we need it for
4470 non-WINDOWSNT builds.
4472 * w32.h: Add #error macro to make sure we don't include w32.h for
4473 Cygwin builds. Remove w32select declarations.
4475 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4476 w32fns.c. w32console.c is WINDOWSNT-only.
4478 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4479 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4481 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4482 (w32_major_version, w32_minor_version, w32_build_number)
4483 (os_subtype, sound_type): Define here
4484 (w32_defined_color): Make color parameter const for consistency
4485 with other _defined_color functions.
4486 (w32_createwindow): Unconditionally call w32_init_class instead of
4487 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4488 through the code is complex and unnecessary because class
4489 registration is practically free.
4490 (w32_name_of_message): New EMACSDEBUG-only function.
4491 (Fset_message_beep): Move here
4492 (Fx_open_connection): Require that the display name for Windows be
4493 "w32" for consistency, emacsclient disambiguation, and maybe, one
4494 day, multi-window-system support.
4495 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4496 Cygwin files for W32 GUI facilities, since these clearly don't
4497 expect Cygwin names.
4498 (_DebPrint): Define.
4499 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4500 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4501 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4502 (w32_last_error): Remove.
4504 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4506 * w32heap.c (syspage_mask): Declare here.
4507 (cache_system_info): Remove.
4509 * w32inevt.c (faked_key): Define globally, not statically.
4510 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4511 (w32_console_toggle_lock_key): Move to w32fns.c.
4513 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4515 * w32proc.c (_DebPrint): Move to w32fns.c.
4516 * w32select.c: Include string.h, stdio.h for Cygwin.
4517 * w32select.h: New File.
4519 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4521 (w32_message_fd): New variable. Under Cygwin, holds the file
4522 descriptor the system used to tell us about pending thread
4525 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4526 that prevented compilation under non-WINDOWSNT systems.
4528 (w32_initialize): Open /dev/windows and assign it to
4529 w32_message_fd. Provide w32 feature.
4531 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4532 (WM_EMACS_INPUT_READY): add.
4533 (prepend_msg, w32_message_fd): Declare globally.
4536 (keyboard_handle): Use only when WINDOWSNT.
4537 (notify_msg_ready): New function. Posts a message to the main
4538 thread's message queue under CYGWIN, which wakes up the main
4539 thread from select(2) by making the /dev/windows file descriptor
4540 ready. Under WINDOWSNT, it sets an event the same way the old
4543 (post, prepend_msg): Actually call notify_msg_ready instead of
4544 setting the input event directly.
4546 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4548 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4549 but it still has blocs in it, don't return it to the system,
4550 instead of aborting. (Bug#12402)
4552 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4554 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4556 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4557 MAC_OS_X_VERSION_10_6.

4567 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4568 MAC_OS_X_VERSION_10_2.
4570 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4572 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4573 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4575 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4576 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4577 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4578 Remove ns_in_resize check.
4579 (ns_clear_frame_area): Remove resize handle code.
4581 * nsfns.m (ns_in_resize): Remove.
4582 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4583 Remove ns_in_resize check.
4585 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4587 Improve sys_siglist detection.
4588 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4589 defined as a macro, as is done in Solaris.
4590 (sys_siglist_entries): New macro.
4591 (save_strsignal): Use it.
4592 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4593 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4595 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4597 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4598 fullscreen/Fullscreen.
4600 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4601 tobar_height is new.
4603 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4604 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4605 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4606 (windowDidResize:): Check for correct window if old style fullscreen.
4607 Capitalize word in comment. Remove incorrect comment.

4609 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4610 error in drawing background.
4611 (toggleFullScreen:): Remove comment. Rearrange calls.
4612 Set toolbar values to zero, save old height in tobar_height.

4620 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4622 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4624 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4625 that time stamps of directories could also be changed.
4626 Don't request the too broad GENERIC_WRITE, only the more restrictive
4627 FILE_WRITE_ATTRIBUTES access rights.
4629 * fileio.c (Fset_file_times): Special-case ignoring errors for
4630 directories only on MSDOS, not on MS-Windows.
4632 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4634 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4636 2012-10-04 Eli Zaretskii <eliz@gnu.org>

4649 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4651 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4652 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4653 like OpenBSD, which has timer_settime but does not declare it.
4654 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4655 whether to use itimerspec-related primitives. All uses of
4656 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4658 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4660 * profiler.c (handle_profiler_signal): Fix a malloc race
4661 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4663 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4665 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4667 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4669 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4670 consistent with the change in return value of 'safe_strsignal'.
4672 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4674 Prefer plain 'static' to 'static inline' (Bug#12541).
4675 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4676 (bidi_set_sor_type, bidi_push_embedding_level)
4677 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

4682 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4683 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4684 Now 'static', not 'static inline'.
4686 Count overruns when profiling; change units to ns.
4687 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4688 Give extra weight to samples after overruns, to attempt to count
4689 the time more accurately.
4690 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4691 the underlying primitives nominally do ns.
4692 (Fprofiler_cpu_start): Document the change. Mention that
4693 the sampling intervals are only approximate.
4695 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4697 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4699 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4700 case for the special 0 coding-system.
4702 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4703 (Fmake_overlay): Remove redundant tests.
4704 (fix_start_end_in_overlays): Remove redundant recentering.
4706 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4708 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4709 Update dependencies.
4711 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4713 Fix a malloc race condition involving strsignal.
4714 A signal can arrive in the middle of a malloc, and Emacs's signal
4715 handler can invoke strsignal, which can invoke malloc, which is
4716 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4717 Fix it by altering the signal handler so that it does not invoke
4719 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4720 * process.c (status_message): Use const pointer, in case strsignal
4721 is #defined to safe_strsignal.
4722 * sysdep.c (sys_siglist, init_signals): Always define and
4723 initialize a substitute sys_siglist if the system does not define
4724 one, even if HAVE_STRSIGNAL.
4725 (safe_strsignal): Rename from strsignal. Always define,
4726 using sys_siglist. Return a const pointer.
4727 * syssignal.h (safe_strsignal): New decl.
4728 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4730 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4732 * w32proc.c (timer_loop): Fix code that waits for timer
4733 expiration, to avoid high CPU usage.
4735 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4737 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4738 (sweep_weak_table): Remove redundant prototypes.
4740 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4742 * emacs.c: Move the inclusion of TERM_HEADER after including
4743 windows.h on WINDOWSNT. This avoids compilation problems with
4746 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4748 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4749 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4750 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4751 as the previous version used 'void *'.
4753 * ralloc.c (ROUNDUP): Fix last change.
4754 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4757 * w32proc.c <disable_itimers>: New static flag.
4758 (init_timers): Initialize it to zero, after creating the critical
4759 sections used by the timer threads.
4760 (term_timers): Set to 1 before deleting the critical sections.
4761 (getitimer, setitimer): If disable_itimers is non-zero, return an
4762 error indication without doing anything. Reported by Fabrice
4763 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4764 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4766 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4769 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4770 term_ntproc after all the other bookkeeping, to get timers working
4771 as long as possible.
4773 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4775 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4776 Suggested by Juri Linkov in
4777 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4779 Prefer plain 'static' to 'static inline' (Bug#12541).
4780 With static functions, modern compilers inline pretty well by
4781 themselves; advice from programmers often hurts as much as it helps.
4782 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4783 this change shrinks the text size of the Emacs executable by 1.1%
4784 without affecting CPU significantly in my benchmark.
4785 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4865 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4867 Revert the FOLLOW-SYMLINKS change for file-attributes.

4869 not enough time to get that tested before the freeze today.
4870 * dired.c (directory_files_internal, Ffile_attributes):
4873 * frame.c (x_report_frame_params): Port better to wider ints.

5000 2012-09-30 Kenichi Handa <handa@gnu.org>
5002 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention

5083 for consistency with other handlers.
5084 (setup_cpu_timer): New function, with much of what used to be in

5086 Prefer timer_settime if available, and prefer
5087 thread cputime clocks, then process cputime clocks, then
5088 monotonic clocks, to the old realtime clock. Use make_timeval
5089 to round more-correctly when falling back to setitimer.
5090 (Fprofiler_cpu_start): Use it.
5091 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5092 Don't assume that passing NULL as the 2nd argument of setitimer
5093 is the same as passing a pointer to all-zero storage.
5094 Ignore SIGPROF afterwards.
5095 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5096 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5097 non-fatal signal handlers. Ignore SIGPROF on startup.
5098 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5099 in profiler.c, since sysdep.c now uses it.
5101 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5102 Suggested by Eli Zaretskii in
5103 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

5114 * alloc.c (Fgarbage_collect):
5115 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
5116 (Fbacktrace_frame): Adjust accordingly.
5118 2012-09-28 Glenn Morris <rgm@gnu.org>
5120 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5121 (Frun_hook_with_args_until_failure): Doc fixes.
5123 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5125 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from

5139 * Makefile.in (LIB_TIMER_TIME): New macro.
5141 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
5142 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
5145 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
5147 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.
5149 2012-09-26 Juanma Barranquero <lekktu@gmail.com>
5151 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
5153 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
5155 * character.h (MAYBE_UNIFY_CHAR): Remove.
5156 * charset.c, charset.h (maybe_unify_char): Now static.
5157 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5158 Since this stuff is now private to charset.c, there's no need for
5159 a public macro and no need to inline by hand.

5162 Stefan Monnier <monnier@iro.umontreal.ca>
5163 Juanma Barranquero <lekktu@gmail.com>

5188 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5190 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5192 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5194 Prefer POSIX timers if available.
5195 They avoid a race if the timer is too close to the current time.
5196 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5197 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5198 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5200 2012-09-25 Eli Zaretskii <eliz@gnu.org>

5203 CHAR_STRING_ADVANCE.
5204 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5205 STRING_CHAR_ADVANCE.
5207 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5209 Move Vlibrary_cache to emacs.c and reset before dumping.
5211 * lisp.h (reset_image_types): Declare.

5214 * image.c (reset_image_types): New function.
5216 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

5223 * w32.h (Vlibrary_cache): Do not declare.
5225 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5227 * w32proc.c (sys_signal): Handle all signals defined by the
5228 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5229 handlers for signals supported by Windows. Don't override
5230 term_ntproc as the handler for SIGABRT.
5231 (sigaction): Rewrite to call sys_signal instead of duplicating its
5233 (sys_kill): Improve commentary.
5235 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5236 consistency with a signature of a signal handler. All callers
5238 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5239 install term_ntproc as a signal handler for SIGABRT, as that
5240 should be done by the dumped Emacs.
5242 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5244 * w32select.c (term_w32select): Protect against repeated
5245 invocation by setting clipboard_owner to NULL after calling
5248 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5249 and term_ntproc to their modified signatures.
5251 * character.c (char_string, string_char): Remove calls to
5252 MAYBE_UNIFY_CHAR. See the discussion starting at
5253 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5256 2012-09-25 Chong Yidong <cyd@gnu.org>
5258 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5260 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5262 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5263 when encountering an unknown bytecode.
5265 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5267 image.c, indent.c: Use bool for booleans.
5268 * dispextern.h (struct image_type): Members valid_p, load, init
5269 now return bool, not int. All uses changed.
5270 * image.c: Omit unnecessary static decls.
5271 (x_create_bitmap_mask, x_build_heuristic_mask):
5272 Return void, not int, since callers don't care about the return value.

5303 2012-09-24 Chong Yidong <cyd@gnu.org>
5305 * chartab.c (Fset_char_table_default): Obsolete function removed.
5307 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5309 Move pid_t related decls out of lisp.h.
5310 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5311 (interruptible_wait_for_termination):
5312 Move these decls from lisp.h to syswait.h, since they use pid_t.
5313 Needed on FreeBSD; see Herbert J. Skuhra in
5314 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5315 * callproc.c: Include syswait.h.

5333 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):

5335 Use bool for boolean.
5336 * gtkutil.c (xg_update_frame_menubar):

5361 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5363 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5364 fatal_error_backtrace.
5366 * w32proc.c (sys_kill): Undo last change: don't do anything when
5367 invoked to deliver SIGABRT to our own process. This is now
5368 handled by emacs_raise.
5370 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5372 * w32term.c (w32_read_socket): Remove leftover reference to
5373 interrupt_input_pending.
5375 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5377 Do not use SA_NODEFER.
5378 Problem reported by Dani Moncayo in
5379 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5381 * sysdep.c (emacs_abort): Do not reset signal handler.
5382 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5383 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5384 wanted even on POSIXish hosts, and it doesn't work on Windows.
5386 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5388 * xterm.c (x_term_init): Call fixup_locale before and after calling
5389 gtk_init (Bug#12392).
5391 2012-09-23 Chong Yidong <cyd@gnu.org>
5393 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5394 Vdynamic_library_alist.
5396 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5397 (Fgnutls_available_p): Caller changed.
5399 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5400 (Flibxml_parse_xml_region): Likewise.
5402 * dispextern.h (struct image_type): Remove arg from init function.
5404 * image.c (Finit_image_library, lookup_image_type)
5405 (define_image_type): Remove now-unneeded second arg.
5406 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5407 (init_tiff_functions, init_gif_functions, init_svg_functions):
5408 Arglist and w32_delayed_load calling convention changed.
5409 (gs_type): Remove init_gs_functions; there is no such function.
5410 (valid_image_p, make_image): Fix caller to lookup_image_type.
5412 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5414 Simplify and avoid signal-handling races (Bug#12471).
5416 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5417 Avoid recursive loop if there's a fatal error in the function itself.
5418 * atimer.c (pending_atimers):
5419 * blockinput.h: Don't include "atimer.h"; no longer needed.
5420 (interrupt_input_pending): Remove. All uses removed.
5421 pending_signals now counts both atimers and ordinary interrupts.
5422 This is less racy than having three separate pending-signal flags.
5423 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5425 Rename from their upper-case counterparts BLOCK_INPUT,
5426 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5427 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5428 This makes it easier to access volatile variables more accurately.
5429 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5430 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5431 that's more reliable if the code is buggy and sets
5432 interrupt_input_blocked to a negative value. All uses changed.
5433 * atimer.c (deliver_alarm_signal):
5434 Remove. No need to deliver this to the parent; any thread can
5435 handle this signal now. All uses replaced by underlying handler.
5436 * atimer.c (turn_on_atimers):
5437 * dispnew.c (handle_window_change_signal):
5438 * emacs.c (handle_danger_signal):
5439 * keyboard.c (kbd_buffer_get_event):
5440 Don't reestablish signal handler; not needed with sigaction.
5441 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5443 Rework to avoid unnecessary accesses to volatile variables.
5444 (UNBLOCK_INPUT_TO): Now a function.
5445 (totally_unblock_input, unblock_input): New decls.
5446 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5447 (init_data): Remove. Necessary stuff now done in init_signal.
5448 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5449 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5450 (fatal_error_code): Remove; no longer needed.
5451 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5452 it doesn't always backtrace. All uses changed. No need to reset
5453 signal to default, since sigaction and/or die does that for us now.
5454 Use emacs_raise (FOO), not kill (getpid (), FOO).
5455 (main): Check more-accurately whether we're dumping.
5456 Move fatal-error setup to sysdep.c
5457 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5458 * gtkutil.c (xg_get_file_name, xg_get_font):
5459 Remove no-longer-needed signal-mask manipulation.
5460 * keyboard.c, process.c (POLL_FOR_INPUT):
5461 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5462 * keyboard.c (read_avail_input): Remove.
5463 All uses replaced by gobble_input.
5464 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5465 (kbd_buffer_store_event_hold, gobble_input):
5466 (record_asynch_buffer_change) [USABLE_SIGIO]:
5467 (store_user_signal_events):
5468 No need to mess with signal mask.
5469 (gobble_input): If blocking input and there are terminals, simply
5470 set pending_signals to 1 and return. All hooks changed to not
5471 worry about whether input is blocked.
5472 (process_pending_signals): Clear pending_signals before processing
5473 them, in case a signal comes in while we're processing.
5474 By convention callers now test pending_signals before calling us.
5475 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5476 New functions, to support changes to blockinput.h.
5477 (handle_input_available_signal): Now extern.
5478 (reinvoke_input_signal): Remove. All uses replaced by
5480 (quit_count): Now volatile, since a signal handler uses it.
5481 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5482 All callers changed. Block SIGINT only if not already blocked.
5483 Clear sigmask reliably, even if Fsignal returns, which it can.
5484 Omit unnecessary accesses to volatile var.
5485 (quit_throw_to_read_char): No need to restore sigmask.
5486 * keyboard.c (gobble_input, handle_user_signal):
5487 * process.c (wait_reading_process_output):
5488 Call signal-handling code rather than killing ourselves.
5489 * lisp.h: Include <float.h>, for...
5490 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5491 (pending_signals): Now volatile.
5492 (syms_of_data): Now const if IEEE floating point.
5493 (handle_input_available_signal) [USABLE_SIGIO]:
5494 (terminate_due_to_signal, record_child_status_change): New decls.
5495 * process.c (create_process): Avoid disaster if memory is exhausted
5496 while we're processing a vfork, by tightening the critical section
5498 (send_process_frame, process_sent_to, handle_pipe_signal)
5499 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5501 (send_process): No need for setjmp/longjmp any more, since the
5502 SIGPIPE stuff is now gone. Instead, report an error if errno
5504 (record_child_status_change): Now extern. PID and W are now args.
5505 Return void, not bool. All callers changed.
5506 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5507 Remove. All uses removed. This bug should be fixed now in a
5509 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5510 and record the child status change directly. This avoids the
5511 need to futz with the signal mask.
5512 (process_fatal_action): Move here from emacs.c.
5513 (emacs_sigaction_flags): New function, containing
5514 much of what used to be in emacs_sigaction_init.
5515 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5516 caught by emacs, to make races less likely.
5517 (deliver_process_signal): Rename from handle_on_main_thread.
5519 (BACKTRACE_LIMIT_MAX): Now at top level.
5520 (thread_backtrace_buffer, threadback_backtrace_pointers):
5522 (deliver_thread_signal, deliver_fatal_thread_signal):
5523 New functions, for more-accurate delivery of thread-specific signals.
5524 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5525 (deliver_arith_signal): Handle in this thread, not
5526 in the main thread, since it's triggered by this thread.
5527 (maybe_fatal_sig): New function.
5528 (init_signals): New arg DUMPING so that we can be more accurate
5529 about whether we're dumping. Caller changed.
5530 Treat thread-specific signals differently from process-general signals.
5531 Block all signals while handling fatal error; that's safer.
5532 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5534 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5535 Ignore SIGPIPE unless batch.
5536 (emacs_backtrace): Output backtrace for the appropriate thread,
5537 which is not necessarily the main thread.
5538 * syssignal.h: Include <stdbool.h>.
5539 (emacs_raise): New macro.
5540 * xterm.c (x_connection_signal): Remove; no longer needed
5541 now that we use sigaction.
5542 (x_connection_closed): No need to mess with sigmask now.
5543 (x_initialize): No need to reset SIGPIPE handler here, since
5544 init_signals does this for us now.
5546 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5548 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5549 background rect may be larger (Bug#12245).
5551 2012-09-23 Chong Yidong <cyd@gnu.org>
5553 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5555 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5557 * .gdbinit: Just stop at fatal_error_backtrace.
5558 See Stefan Monnier's request in
5559 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5560 Remove no-longer-used query of system type.
5562 2012-09-22 Chong Yidong <cyd@gnu.org>
5564 * search.c (Freplace_match): Doc fix (Bug#12325).
5566 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5568 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5569 (Fline_end_position): Doc fix.
5571 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5573 2012-09-22 Chong Yidong <cyd@gnu.org>
5575 * dispextern.h (struct image_type): Add new slot, storing a type
5576 initialization function.
5578 * image.c (define_image_type): Call the image initializer function
5579 if it is defined. Arguments and return value changed.
5580 (valid_image_p, make_image): Callers changed.
5581 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5582 (gif_type, imagemagick_type, svg_type, gs_type):
5583 Add initialization functions.
5584 (Finit_image_library): Call lookup_image_type.
5585 (CHECK_LIB_AVAILABLE): Macro deleted.
5586 (lookup_image_type): Call define_image_type here, rather than via
5587 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5588 (syms_of_image): Move define_image_type calls for xbm_type and
5589 pbm_type to lookup_image_type.
5591 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5593 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5594 'idle_timers' from here ...
5595 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5596 lists, to avoid infloops when the timer does something stupid,
5597 like reinvoke itself with the same or smaller time-out.
5600 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5602 * window.c (Fsplit_window_internal): Handle only Qt value of
5603 Vwindow_combination_limit separately.
5604 (Qtemp_buffer_resize): New symbol.
5605 (Vwindow_combination_limit): New default value.
5608 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5610 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5611 the new overlay string. (Bug#10159)
5613 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5615 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5616 or that fprintf is async-signal-safe. POSIX doesn't require
5619 2012-09-22 Chong Yidong <cyd@gnu.org>
5621 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5624 2012-09-22 Kenichi Handa <handa@gnu.org>
5626 * composite.c (composition_reseat_it): Handle the case that a
5627 grapheme cluster is not covered by a single font (Bug#12352).
5629 2012-09-21 Chong Yidong <cyd@gnu.org>
5631 * image.c (define_image_type): Avoid adding duplicate types to
5632 image_types (Bug#12463). Suggested by Jörg Walter.
5634 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5636 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5637 (print_load_command_name): Add case LC_DATA_IN_CODE.
5638 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5640 2012-09-21 Glenn Morris <rgm@gnu.org>
5642 * eval.c (Frun_hook_with_args_until_success)
5643 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5645 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5647 * fileio.c (Ffile_selinux_context): Only call freecon when
5648 lgetfilecon succeeded.
5649 (Fset_file_selinux_context): Likewise. (Bug#12444)
5651 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5653 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5654 reordering, locate the cursor by calling set_cursor_from_row; if
5655 that fails, clear the desired glyph matrix before returning a
5656 failure indication to the caller. Fixes leaving garbled display
5657 when fast scrolling with a down-key. (Bug#12403)
5658 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5659 scrolling through multibyte text.
5661 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5663 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5664 calling mark_vectorlike since that's the one that marks the window.
5665 (mark_discard_killed_buffers): Mark the final cdr.
5666 * window.h (struct window): Move prev/next_buffers to the
5667 non-standard fields.
5668 * window.c (make_window): Initialize prev/next_buffers manually.
5670 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5672 Omit unused arg EXPECTED from socket hooks.
5673 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5674 * nsterm.m (ns_term_init):
5675 * termhooks.h (struct terminal.read_socket_hook):
5676 * w32inevt.c (w32_console_read_socket):
5677 * w32term.c (w32_read_socket):
5678 * xterm.c (XTread_socket):
5679 Omit unused arg EXPECTED. All callers changed.
5680 (store_user_signal_events): Return void, not int, since callers no
5681 longer care about the return value. All uses changed.
5683 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5685 * w32gui.h (XParseGeometry): Do not declare.
5687 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5689 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5690 Ignore 'expected'. See Eli Zaretskii in
5691 <http://bugs.gnu.org/12471#8> (last line).
5693 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5694 (XParseGeometry): Now static. Substitute extremal values for
5695 values that are out of range.
5697 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5699 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5701 * nsfns.m (XParseGeometry): Remove.
5702 (Fx_create_frame): Call x_set_offset to correctly interpret
5703 top_pos in geometry.
5705 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5706 (Fx_parse_geometry): If there is a space in string, call
5707 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5709 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5711 * search.c (scan_buffer): Use character positions in calls to
5712 region_cache_forward and region_cache_backward, not byte
5713 positions. (Bug#12196)
5715 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5716 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5718 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5719 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5720 emacs_blocked_malloc, now deleted.
5722 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5724 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5725 The workaround was for improving performance on Solaris 2.4, but
5726 is getting in the way now. Emacs will still work if someone is
5727 still running Solaris 2.4 in a museum somewhere; Sun dropped
5728 support for Solaris 2.4 in 2003.
5729 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5730 * process.c (create_process) [HAVE_WORKING_VFORK]:
5731 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5732 since Emacs no longer uses vfork on that platform.
5734 2012-09-17 Glenn Morris <rgm@gnu.org>
5736 * emacs.c: Use COPYRIGHT.
5738 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5740 Remove configure's --without-sync-input option (Bug#12450).
5741 When auditing signal-handling in preparation for cleaning it up,
5742 I found that SYNC_INPUT has race conditions and would be a real
5743 pain to fix. Since it's an undocumented and deprecated
5744 configure-time option, now seems like a good time to remove it.
5745 Also see <http://bugs.gnu.org/11080#16>.
5746 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5747 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5748 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5749 (malloc_hysteresis):
5750 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5751 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5752 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5753 (dont_register_blocks, bytes_used_when_reconsidered)
5754 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5755 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5756 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5757 Remove. All uses removed.
5758 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5759 implementation, one that depends on whether the new macro
5760 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5762 * atimer.c (run_timers, handle_alarm_signal):
5763 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5764 (handle_async_input, process_pending_signals)
5765 (handle_input_available_signal, init_keyboard):
5766 * nsterm.m (ns_read_socket):
5767 * process.c (wait_reading_process_output):
5768 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5769 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5771 * xterm.c (XTread_socket):
5773 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5774 * eval.c (handling_signal): Remove. All uses removed.
5775 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5776 All uses replaced with the SYNC_INPUT version.
5777 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5779 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5782 * font.c (Ffont_shape_gstring): Remove unused local.
5784 2012-09-16 Glenn Morris <rgm@gnu.org>
5786 * Makefile.in (clean): No longer run nextstep's clean.
5788 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5790 (ns-app): Move here from ns.mk, and simplify.
5791 (clean): Simplify nextstep entry.
5792 * ns.mk: Remove file.
5794 2012-09-17 Kenichi Handa <handa@gnu.org>
5796 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5797 not covert the last few charactes.
5799 2012-09-16 Kenichi Handa <handa@gnu.org>
5801 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5802 here, but just check the validity of glyphs in the glyph-string.
5804 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5806 * window.c (Fwindow_parameter, Fset_window_parameter):
5807 Accept any window as argument (Bug#12452).
5809 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5811 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5812 to ns_term_init to avoid memory leak.
5814 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5815 explicit retain/release.
5816 (ns_term_init): Only allow one display. Initialize outerpool and
5819 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5821 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5822 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5823 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5824 the Microsoft problem in a different way, by altering ../nt/config.nt.
5826 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5841 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5842 by lisp.h. This completes removal of setjmp.h inclusion
5843 erroneously announced in the previous commit. (Bug#12446)
5845 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5848 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5849 not defined as a macro. The latter happens on MS-Windows.
5852 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5854 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5855 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5856 Some instances of '#include <setjmp.h>' removed, if the
5857 only reason for the instance was because "lisp.h" was included.
5858 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5859 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5860 and _longjmp with the new symbols. Emacs already uses _setjmp if
5861 available, so this change affects only POSIXish hosts that have
5862 sigsetjmp but not _setjmp, such as some versions of Solaris and
5863 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5864 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5865 (png_load_body) [HAVE_PNG]:
5866 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5867 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5868 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5869 since PNG requires jmp_buf. This is the only exception to the
5870 general rule that we now use sys_setjmp and sys_longjmp.
5871 This exception is OK since this code does not change the signal
5872 mask or longjmp out of a signal handler.
5874 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5876 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5877 Include "syssignal.h", for 'main_thread'.
5879 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5881 Avoid out-of-range marker position (Bug#12426).
5882 * insdel.c (replace_range, replace_range_2):
5883 Adjust markers before overlays, as suggested by comments.
5884 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5885 Remove redundant check before calling offset_intervals.
5887 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5889 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5890 current buffer (Bug#12387).
5892 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5894 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5896 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5898 Use a more backwards-compatible timer format (Bug#12430).
5899 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5900 vector element, not from the 4th, since PSECS is now at the end.
5901 (Fcurrent_idle_time): Doc fix.
5903 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5905 Function to mark objects and remove killed buffers at once.
5906 * alloc.c (discard_killed_buffers): Rename to ...
5907 (mark_discard_killed buffers) ... new name. Add marking
5908 of remaining objects. Fix comment. Adjust users.
5909 (mark_object): Do not touch frame buffer lists here.
5910 * frame.c (delete_frame): Reset frame buffer lists here.
5912 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5914 Better workaround for GNOME bug when --enable-gcc-warnings.
5915 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5916 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5917 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5919 Simplify SIGIO usage (Bug#12408).
5920 The code that dealt with SIGIO was crufty and confusing, e.g., it
5921 played tricks like "#undef SIGIO" but these tricks were not used
5922 consistently. Simplify mostly by not #undeffing standard symbols,
5923 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5924 or not as we please) rather than "defined SIGIO" (standard symbol
5925 that we probably shouldn't #undef).
5926 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5927 Modules that need it can include it.
5928 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5929 * dispextern.h (ignore_sigio): New decl.
5930 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5931 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5932 * emacs.c (shut_down_emacs):
5933 * keyboard.c (kbd_buffer_store_event_hold):
5934 Use ignore_sigio rather than invoking 'signal' directly.
5935 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5937 (FIONREAD, SIGIO): Do not #undef.
5938 (tty_read_avail_input): Use #error rather than a syntax error.
5939 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5940 for I_PIPE, used by SETUP_SLAVE_PTY.
5941 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5942 * sysdep.c (croak): Remove; no longer needed. This bit of
5943 temporary code, with Fred N. Fish's comment that it's temporary,
5944 has been in Emacs since at least 1992!
5945 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5946 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5947 * syssignal.h (croak): Remove decl.
5948 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5949 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5950 now that we're termios-only.
5951 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5952 * term.c (dissociate_if_controlling_tty): Use #error rather than
5955 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5956 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5957 to work around GNOME bug 683906.
5958 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5959 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5960 This works around GCC bug 54561.
5962 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5964 More fixes for 'volatile' and setjmp/longjmp.
5965 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5966 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5967 (png_load_body) [HAVE_PNG]:
5968 (jpeg_load_body) [HAVE_JPEG]:
5969 New function, with most of the old parent function's body.
5970 (png_load) [HAVE_PNG]:
5971 (jpeg_load) [HAVE_JPEG]:
5972 Invoke the new function, to avoid longjmp munging our locals.
5973 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5974 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5975 longjmp is passed 2, as the C standard doesn't guarantee this.
5976 Instead, store the failure code into mgr->failure_code.
5978 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5980 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5981 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5982 (syms_of_keyboard): Remove support for unread-command-char.
5984 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5986 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5987 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5988 violation. (Bug#12426)
5990 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5992 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5994 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5996 * eval.c: Add `inhibit-debugger'.
5997 (Qinhibit_debugger): New symbol.
5998 (call_debugger): Bind it instead of Qdebug_on_error.
5999 (maybe_call_debugger): Test Vinhibit_debugger.
6000 (syms_of_eval): Define inhibit-debugger.
6001 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6002 (syms_of_xdisp): Remove inhibit-debug-on-message.
6004 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6006 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6007 If a nonvolatile local variable is written before a _longjmp to
6008 the frame containing the variable, and is read after the _longjmp,
6009 the value read is indeterminate. Some local variables of type
6010 'struct handler' and 'struct catchtag' are used in this way, so
6011 mark each of their slots as volatile if the slot can be set before
6012 _longjmp and read afterwards.
6013 * lisp.h (struct handler): var and chosen_clause are now volatile.
6014 (struct catchtag): val, next, and pdlcount are now volatile.
6016 * bidi.c (bidi_push_it, bidi_pop_it):
6017 * fns.c (copy_hash_table):
6018 * image.c (define_image_type):
6019 * keyboard.c (kbd_buffer_store_event_hold):
6020 * process.c (Fprocess_send_eof):
6021 * xfaces.c (x_create_gc) [HAVE_NS]:
6022 * xgselect.c (xg_select):
6023 Prefer assignment to memcpy when either will do.
6025 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6026 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6027 time an item is removed. No need to mark this function 'inline';
6028 the compiler knows better than we do.
6030 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6032 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6033 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6034 to change_frame_size (Bug#12388).
6035 (windowDidResize:): Pass YES to updateFrameSize.
6037 * nsterm.h: Add delay parameter to updateFrameSize.
6039 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6041 Discard killed buffers from deleted window and frame objects.
6042 This reduces an amount of references to killed buffers and
6043 helps GC to reclaim them faster.
6044 * alloc.c (discard_killed_buffers): New function.
6045 (mark_object): Use it for deleted windows and frames.
6046 (mark_object): If symbol's value is set up for a killed buffer
6047 or deleted frame, restore its global binding.
6048 * data.c (swap_in_global_binding): Add GC notice.
6049 (swap_in_symval_forwarding): Use convenient set_blv_where.
6050 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6051 * window.h: ... to here.
6053 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6055 Convenient macro to check whether the buffer is live.
6056 * buffer.h (BUFFER_LIVE_P): New macro.
6057 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6058 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6060 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6062 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6063 composition cases (Bug#12364).
6065 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6066 overhang of succeeding glyphs overlapping box cursor.
6068 * w32term.c (x_draw_glyph_string): Likewise.
6070 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6072 Simplify, document, and port floating-point (Bug#12381).
6073 The porting part of this patch fixes bugs on non-IEEE platforms
6074 with frexp, ldexp, logb.
6075 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6077 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6078 support, by removing commented-out code and briefly listing the
6079 C89 functions excluded. The commented-out stuff was confusing
6080 maintenance, e.g., we thought we needed cbrt but it was commented out.
6081 (logb): Remove decl; no longer needed.
6082 (isfinite): New macro, if not already supplied.
6083 (isnan): Don't replace any existing macro.
6084 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6085 are present on all C89 platforms.
6086 (Ffrexp): Do not special-case zero, as frexp does the right thing
6088 (Flogb): Do not use logb, as it doesn't have the desired meaning
6089 on hosts that use non-base-2 floating point. Instead, stick with
6090 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6091 frexp, to avoid getting an unspecified result.
6093 * xdisp.c (Qinhibit_debug_on_message): Now static.
6095 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6097 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6098 NSBezierPath (Bug#12131).
6100 2012-09-10 Chong Yidong <cyd@gnu.org>
6102 * fns.c (Fdelq, Fdelete): Doc fix.
6104 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6106 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6107 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6109 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6111 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6112 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6115 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6117 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6118 left fringe if the window has a left margin. This avoids leaving
6119 traces of the cursor because its leftmost pixel is not drawn over.
6121 * dispnew.c (update_window_line): When the left margin area of a
6122 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6123 that screen line. (Bug#12277)
6125 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6127 Assume C89 or later for math functions (Bug#12381).
6128 This simplifies the code, and makes it a bit smaller and faster,
6129 and (most important) makes it easier to clean up signal handling
6130 since we can stop worring about floating-point exceptions in
6131 library code. That was a problem before C89, but the problem
6132 went away many years ago on all practical Emacs targets.
6133 * data.c, image.c, lread.c, print.c:
6134 Don't include <math.h>; no longer needed.
6135 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6136 might be autoconfigured, as that never happens.
6138 * doprnt.c (DBL_MAX_10_EXP):
6139 * print.c (DBL_DIG):
6140 Remove. C89 or later always defines these.
6141 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6142 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6143 (arith_error, domain_error, domain_error2):
6144 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6145 no longer needed -- we simply return what C returns. All uses removed.
6146 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6148 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6149 Remove. All uses expanded, as these macros are no longer used
6150 more than once and are now more trouble than they're worth.
6151 (Ftan): Use tan, not sin / cos.
6152 (Flogb): Assume C89 frexp.
6153 (fmod_float): Assume C89 fmod.
6154 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6155 (init_floatfns): Remove. All uses removed.
6157 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6159 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6160 compositeToPoint for OSX < 10.6 (Bug#12390).
6162 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6164 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6165 This produces more-accurate results.
6167 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6169 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6170 changes (Bug#12088).
6172 2012-09-08 Chong Yidong <cyd@gnu.org>
6174 * syntax.c (Fstring_to_syntax): Doc fix.
6176 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6178 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6179 in the internal border.
6180 (x_set_window_size): Remove static variables and their usage.
6181 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6182 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6183 Remove fringe/internal border adjustment (Bug#11052).
6184 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6185 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6186 (ns_fix_rect_ibw): Remove.
6187 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6188 (ns_dumpglyphs_box_or_relief): Ditto.
6189 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6191 (ns_dumpglyphs_image): Ditto.
6192 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6194 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6195 their usage. Add fringe_extended_p and its use as in other terms.
6196 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6197 scroll bar was removed.
6198 (updateFrameSize): New function.
6199 (windowDidResize): Move code to updateFrameSize and call it.
6201 * nsterm.h (EmacsView): Add updateFrameSize.
6203 2012-09-07 Chong Yidong <cyd@gnu.org>
6205 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6207 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6209 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6211 More signal-handler cleanup (Bug#12327).
6212 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6213 Problem introduced when merging patches. Noted by Eli Zaretskii in
6214 <http://bugs.gnu.org/12327#67>.
6215 * floatfns.c: Comment fix.
6216 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6217 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6218 and anyway the declaration is harmless even if SIGDANGER is not defined.
6219 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6220 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6221 source files not surprisingly expected syssignal.h to define, or
6222 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6223 Include <sys/ioctl.h>, for FIONREAD.
6224 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6225 This eliminates a problem whereby other files mysteriously had
6226 to include "syssignal.h" before including "systty.h" if they
6227 wanted to use "#ifdef SIGIO".
6229 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6231 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6233 * w32.c (sigemptyset): Empty the set.
6234 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6236 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6238 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6240 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6241 (mark_object): Likewise for frame objects.
6243 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6245 * syssignal.h (handle_on_main_thread): Always declare,
6246 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6247 This ports to platforms without HAVE_PTHREAD.
6249 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6251 Signal-handler cleanup (Bug#12327).
6252 Emacs's signal handlers were written in the old 4.2BSD style with
6253 sigblock and sigmask and so forth, and this led to some
6254 inefficiencies and confusion. Rewrite these to use
6255 pthread_sigmask etc. without copying signal sets around. Also,
6256 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6257 'signal', and instead use functions that do not attempt to take
6258 over the system name space. This patch causes Emacs's text
6259 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6260 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6261 Do not include <signal.h> or "syssignal.h", as these
6262 modules do not use signals.
6263 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6264 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6265 Do not include <signal.h>, as "syssignal.h" does that for us now.
6266 * atimer.c (sigmask_atimers): New function.
6267 (block_atimers, unblock_atimers): New functions,
6268 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6270 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6271 no longer needed here.
6272 * emacs.c (main): Inspect existing signal handler with sigaction,
6273 so that there's no need to block and unblock SIGHUP.
6274 * sysdep.c (struct save_signal): New member 'action', replacing
6275 old member 'handler'.
6276 (save_signal_handlers, restore_signal_handlers):
6277 Use sigaction instead of 'signal' to save and restore.
6278 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6279 New function. All users of 'signal' modified to use set_sighandler
6280 if they're writeonly, and to use sys_signal if they're read+write.
6281 (emacs_sigaction_init, forwarded_signal): New functions.
6282 (sys_signal): Remove. All uses replaced by calls to sigaction
6283 and emacs_sigaction_init, or by direct calls to 'signal'.
6284 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6285 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6286 all uses replaced by pthread_sigmask etc. calls.
6287 * syssignal.h: Include <signal.h>.
6288 (emacs_sigaction_init, forwarded_signal): New decls.
6289 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6290 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6291 (sigmask, sys_sigmask): Remove; no longer needed.
6292 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6293 (sigblock, sigunblock, sigfree):
6294 (sigsetmask) [!defined sigsetmask]:
6295 Remove. All uses replaced by pthread_sigmask.
6296 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6297 no longer need to be replaced, and its typical old uses
6298 are now done via emacs_sigaction_init and sigaction.
6299 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6300 (sys_sigdel): Remove; unused.
6301 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6303 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6305 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6306 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6308 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6310 Explicitly mark buffer_defaults and buffer_local_symbols.
6311 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6312 mark_local_symbols here.
6313 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6314 since special buffers aren't marked here any more.
6315 (allocate_buffer): Chain new buffer with all_buffers here...
6316 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6318 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6319 (syms_of_buffer): Remove staticpro of the above.
6320 (init_buffer_once): Set names for buffer_defaults and
6321 buffer_local_symbols.
6323 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6325 Use bool for booleans in font-related modules.
6326 * font.c (font_intern_prop, font_style_to_value)
6327 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6328 (generate_otf_features, font_check_otf_features, font_check_otf)
6329 (font_match_p, font_list_entities, font_at):
6330 * fontset.c (fontset_id_valid_p, reorder_font_vector
6331 (fontset_find_font, Fset_fontset_font)
6332 (face_suitable_for_char_p) [0]:
6333 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6334 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6335 (m17n_flt_initialized, ftfont_shape_by_flt):
6336 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6337 * nsfont.m (nsfont_draw):
6338 * w32font.c (w32font_draw):
6339 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6340 Use bool for booleans.
6341 * font.h: Adjust to above API changes.
6342 (struct font, struct font_driver, struct font_driver_list):
6343 Use bool for booleans.
6344 (struct font): Remove useless member encoding_type.
6346 * fontset.c, xftfont.c: Omit unnecessary static decls.
6348 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6350 * alloc.c (mark_object): Revert window marking code
6351 since it's unsafe for the Fset_window_configuration.
6353 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6355 Fix race conditions with signal handlers and errno (Bug#12327).
6356 Be more systematic about preserving errno whenever a signal
6357 handler returns, even if it's not in the main thread. Do this by
6358 renaming signal handlers to distinguish between signal delivery
6359 and signal handling. All uses changed.
6360 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6361 * data.c (deliver_arith_signal): Rename from arith_error.
6362 * dispnew.c (deliver_window_change_signal): Rename from
6363 window_change_signal.
6364 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6365 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6366 * keyboard.c (deliver_input_available_signal): Rename from
6367 input_available_signal.
6368 (deliver_user_signal): Rename from handle_user_signal.
6369 (deliver_interrupt_signal): Rename from interrupt_signal.
6370 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6371 (deliver_child_signal): Rename from sigchld_handler.
6372 * atimer.c (handle_alarm_signal):
6373 * data.c (handle_arith_signal):
6374 * dispnew.c (handle_window_change_signal):
6375 * emacs.c (handle_fatal_signal, handle_danger_signal):
6376 * keyboard.c (handle_input_available_signal):
6377 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6378 * process.c (handle_pipe_signal, handle_child_signal):
6379 New functions, with the actual signal-handling code taken from the
6380 original respective signal handlers, sans the sporadic attempts to
6381 preserve errno, since that's now done by handle_on_main_thread.
6382 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6383 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6384 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6386 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6387 Move initialization of main_thread to sysdep.c's init_signals.
6388 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6389 our usage, and simplifies the mainline code.
6390 (record_child_status_change): New static function, as a helper
6391 for handle_child_signal, and with most of the old child handler's
6393 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6394 (handle_child_signal): Use the above.
6395 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6396 Moved here from emacs.c.
6397 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6398 code moved here from emacs.c's main function.
6399 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6400 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6401 This lets callers save and restore errno properly.
6403 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6405 Remove redundant or unused things here and there.
6406 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6407 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6408 * editfns.c (Fcompare_buffer_substrings): Likewise.
6409 * frame.h (struct terminal, struct font_driver_list):
6410 Remove redundant declarations.
6411 * window.h (Qleft, Qright): Likewise.
6413 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6415 Do not mark objects from deleted buffers, windows and frames.
6416 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6417 (mark_object): Likewise for windows and frames.
6419 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6421 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6422 buffer_defaults and buffer_local_symbols as valid objects.
6423 Return special value to denote them.
6425 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6427 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6428 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6429 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6430 (file_name_absolute_p, Fsubstitute_in_file_name):
6431 (check_executable, check_writable, Ffile_accessible_directory_p)
6432 (Fset_file_selinux_context, Fdefault_file_modes)
6433 (Finsert_file_contents, choose_write_coding_system)
6434 (Fwrite_region, build_annotations, a_write, e_write)
6436 * filelock.c (boot_time_initialized, get_boot_time)
6437 (get_boot_time_1, lock_file_1, within_one_second):
6438 * floatfns.c (in_float):
6439 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6440 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6441 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6442 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6443 * window.c (compare_window_configurations):
6444 Use bool for booleans.
6445 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6446 (Fdefault_file_modes): Now mode_t, not int, for modes.
6447 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6448 (internal_delete_file): Now returns void, not a (boolean) int,
6449 since nobody was looking at the return value.
6450 * lisp.h, window.h: Adjust to above API changes.
6452 * xdisp.c (set_message): Simplify and reindent last change.
6454 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6456 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6458 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6460 * eval.c (call_debugger): Make the function non-static so that we
6461 can call it from set_message.
6463 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6464 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6466 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6468 Give more-useful info on a fatal error (Bug#12328).
6469 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6470 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6471 of doing the work ourselves.
6472 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6473 do most of the work.
6474 (fatal_error_backtrace): New function, taken from the guts
6475 of the old fatal_error_signal, but with a new option to output
6477 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6478 info about the signal than just its number.
6479 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6480 * sysdep.c: Include <execinfo.h>
6481 (emacs_backtrace): New function, taken partly from the previous
6482 code of the 'die' function.
6483 (emacs_abort): Call fatal_error_backtrace rather than abort.
6485 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6487 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6488 eager (load-time) macro-expansion.
6489 * lisp.mk (lisp): Add macroexp.
6491 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6493 Simplify redefinition of 'abort' (Bug#12316).
6494 Do not try to redefine the 'abort' function. Instead, redo
6495 the code so that it calls 'emacs_abort' rather than 'abort'.
6496 This removes the need for the NO_ABORT configure-time macro
6497 and makes it easier to change the abort code to do a backtrace.
6498 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6499 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6500 Remove; sysdep.c's emacs_abort now takes its place.
6501 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6502 'abort' changed to use 'emacs_abort'.
6503 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6504 (abort) [!defined abort]: Rename to ...
6505 (emacs_abort): ... new name.
6506 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6507 the place of the old 'abort' in emacs.c.
6508 * w32.c, w32fns.c (abort): Do not #undef.
6509 * w32.c (emacs_abort): Rename from w32_abort.
6511 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6513 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6514 offsets[j].dv, since the y axis of the screen coordinates points
6515 down, while the y axis of the font definition coordinates points
6516 up. This fixes display of Arabic diacritics such as KASRA and
6517 KASRATAN. (Bug#11860)
6519 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6521 Be more systematic about _setjmp vs setjmp.
6522 * alloc.c (test_setjmp, mark_stack):
6523 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6524 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6525 (png_load, my_error_exit, jpeg_load):
6526 * process.c (send_process_trap, send_process):
6527 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6528 The underscored versions are up to 30x faster on some hosts.
6529 Formerly, the code used setjmp+longjmp sometimes and
6530 _setjmp+_longjmp at other times, with no particular reason to
6531 prefer setjmp+longjmp.
6533 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6535 Fix minor problem found by static checking.
6536 * buffer.c (Fdelete_all_overlays): Return nil.
6538 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6540 * buffer.c (Fdelete_all_overlays): New function.
6542 2012-09-03 Chong Yidong <cyd@gnu.org>
6544 * gtkutil.c: Add extern decl for Qxft.
6546 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6560 All callers changed.
6561 * eval.c (interactive_p): Omit always-true boolean argument
6562 EXCLUDE_SUBRS_P. All callers changed.
6563 * dispextern.h, lisp.h: Reflect above API changes.
6564 * firstfile.c (dummy): Use the address of 'main', whose signature
6565 won't change, instead of the address of 'initialize', whose
6566 signature just changed from int to bool.
6567 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6568 * msdos.c (fatal_error_in_progress): ... from here.
6569 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6571 (redisplay_internal, unwind_redisplay): Simply clear
6572 REDISPLAYING_P when unwinding, instead of saving its previous,
6573 always-false value and then restoring it.
6575 Clean up some extern decls.
6576 Mostly, this hoists extern decls out of .c files and into .h files.
6577 That way, we're more likely to catch errors if the interfaces change.
6578 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6579 declare xg_mark_data.
6580 * dispextern.h (x_frame_parm_handlers):
6582 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

6596 * widget.c (free_frame_faces):
6597 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6598 * xfont.c (x_clear_errors):
6599 * xterm.c (x_frame_parm_handlers):
6600 Remove now-redundant extern decls.
6601 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6602 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6604 * xfaces.c: Remove unnecessary static decls.
6605 * xterm.c (updating_frame): Remove decl of nonexistent object.
6607 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6608 when building globals.h, as the objects that are not built on
6609 this host are not needed to compile C files on this host.
6611 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6613 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6627 (make_buffer_string, make_buffer_string_both)
6628 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

6639 (get_property_and_range, compare_string_intervals)
6640 (set_intervals_multibyte_1, set_intervals_multibyte):
6641 * keyboard.c (decode_timer):
6642 Use bool for boolean.
6643 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6644 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
6646 2012-09-02 Chong Yidong <cyd@gnu.org>
6648 * keymap.c (push_key_description): Print M-TAB as C-M-i
6651 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6653 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6654 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

6659 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
6661 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6663 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6664 more than one grapheme cluster passed to the shaper: compute the
6665 offset adjustment values separately for each cluster. (Bug#11860)
6667 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6668 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6669 about implicit conversions from integer to pointer.
6671 2012-09-01 Daniel Colascione <dancol@dancol.org>
6673 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6674 system used too early.
6676 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6678 Better seed support for (random).

6707 * process.c: Include TERM_HEADER instead of listing all possible
6708 window-system headers.
6710 * nsterm.h: Remove declarations now in frame.h.
6711 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
6713 * menu.c: Include TERM_HEADER instead of listing all possible
6714 window-system headers.
6716 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6719 * keyboard.c: Include TERM_HEADER instead of listing all possible
6720 window-system headers.
6722 * image.c: Include TERM_HEADER instead of listing all possible
6723 window-system headers. Declare Vlibrary_cache when compiling for
6726 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6727 window system declarations.
6729 * frame.h: Move common functions here: set_frame_menubar,
6730 x_set_window_size, x_sync, x_get_focus_frame,
6731 x_set_mouse_position, x_set_mouse_pixel_position,
6732 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6753 the current window system; include in list of objects to link into
6756 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6758 Remove mark_ttys function and fix tty_display_info initialization.
6759 * lisp.h (mark_ttys): Remove prototype.
6760 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6761 to mark_ttys because all possible values of 'top_frame' slot are
6762 the frames which are reachable from Vframe_list.
6763 * term.c (mark_ttys): Remove.
6764 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6766 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6768 Change struct frame bitfields from unsigned char to unsigned.
6769 * frame.h (struct frame): Change type of 'display_preempted',

6771 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6772 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6773 bitfields from unsigned char to unsigned.

6786 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6788 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6789 for GCC 4.7.1 x86-64.
6791 2012-08-30 Glenn Morris <rgm@gnu.org>
6793 * lread.c (init_lread): For out-of-tree builds, only add the
6794 source directory's site-lisp dir to the load-path if it exists,
6795 consistent with in-tree builds. (Bug#12302)
6797 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6799 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6801 (windowShouldClose:): Set window_closed.
6802 (dealloc): New member, free button_values.
6803 (process_dialog:): Make member function. Remove window argument,
6804 replace window with self. Count buttons and allocate and store values

6807 with tag. Remove return self, declare return value as void.
6808 (addString:row:): Remove return self, declare return value as void.
6809 (addSplit): Remove return self, declare return value as void.
6810 (clicked:): Remove return self, declare return value as void.
6811 Set dialog_return to button_values[seltag]. Code formatting change.
6812 (initFromContents:isQuestion:): Adjust call to process_dialog.
6813 Code formatting change.
6814 (timeout_handler:): Set timer_fired to YES.
6815 (runDialogAt:): Set timer_fired to NO.
6816 Handle click on close button as quit.
6818 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6819 Add window_closed and button_values. Add void as return value for
6820 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6821 Add process_dialog as new member.
6823 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6825 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6826 is not one of the heaps we manage. (Bug#12242)
6828 2012-08-28 Glenn Morris <rgm@gnu.org>
6830 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

6886 (change_frame_size_1, sit_for):
6887 Use bool for boolean.
6888 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6889 and remove last int (actually boolean) argument, which was always 0.
6890 All callers changed.
6891 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6892 * dispextern.h (struct composition_it): Use bool for boolean.
6893 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6894 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6895 * dired.c (file_name_completion):
6896 Use bool for boolean. (This was missed in an earlier change.)
6898 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6900 * window.c (Fset_window_configuration): Revert first part of
6903 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6905 * nsterm.h (NSPanel): New class variable dialog_return.
6907 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6908 Initialize dialog_return.
6909 (windowShouldClose:): Use stop instead of stopModalWithCode.
6910 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6911 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6913 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

6958 Use bool for booleans.
6959 * coding.h, lisp.h: Reflect above API changes.
6960 * coding.c: Remove unnecessary static function decls.
6961 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6962 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6963 not a boolean 'int', since callers never look at the return value.
6964 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6965 * coding.h (decoding_buffer_size, encoding_buffer_size)
6966 (emacs_mule_string_char): Remove unused extern decls.
6967 (struct iso_2022_spec, struct coding_system):

6969 (struct emacs_mule_spec): Remove unused field 'full_support'.
6970 All initializations removed.
6971 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6973 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6975 Fix spare memory change (Bug#12286).
6976 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6977 (valid_lisp_object_p): Likewise.
6979 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6981 * window.c (Fset_window_configuration): Record any window's old
6982 buffer if it's replaced (see Bug#8789). If the new current
6983 buffer doesn't appear in the selected window, go to its old
6986 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6988 Special MEM_TYPE_SPARE to denote reserved memory.
6989 * alloc.c (enum mem_type): New memory type.
6990 (refill_memory_reserve): Use new type for spare memory.
6991 This prevents live_cons_p and live_string_p from incorrect
6992 detection of uninitialized objects from spare memory as live.
6994 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6997 * Makefile.in (.PHONY): versioclean -> versionclean.
6999 Remove unused external symbols.
7000 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7001 * window.c (Qwindow_valid_p, decode_valid_window):
7002 Now static, not extern.
7003 * data.c (Qinterval): Remove; unused.
7004 (syms_of_data): Do not define 'interval'.
7005 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7006 * window.h (decode_valid_window):
7009 * character.c, charset.c, chartab.c: Use bool for booleans.

7019 (char_table_set_range, optimize_sub_char_table)
7020 (map_sub_char_table):
7021 Use bool for boolean.
7022 * character.c (str_to_unibyte): Omit last boolean argument; it was
7023 always 0. All callers changed.
7024 * character.h, charset.h: Adjust to match previous changes.
7025 * character.h (char_printable_p): Remove decl of nonexistent function.
7026 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7027 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7028 are all boolean, so make them single-bit bitfields.
7030 * lisp.h (ASET): Remove attempt to detect side effects.
7031 It was meant to be temporary and it often doesn't work,
7032 because when IDX has side effects the behavior of IDX==IDX
7033 is undefined. See Stefan Monnier in
7034 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7036 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7038 * lisp.h (functionp): New function (extracted from Ffunctionp).
7039 (FUNCTIONP): Use it.
7040 * eval.c (Ffunctionp): Use it.
7042 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7044 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7045 as that's faster and simpler than static storage. Don't bother
7046 with the g_main_context_query overhead if g_main_context_pending
7047 says no events are pending.
7048 (gfds, gfds_size): Remove these static vars.
7049 (xgselect_initialize): Remove; no longer needed.
7050 All uses and decls removed.
7052 * emacs.c (fatal_error_signal_hook): Remove.
7053 All uses removed. This leftover from old code was always 0.
7055 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7056 * casefiddle.c (casify_object, casify_region):
7057 * casetab.c (set_case_table):
7058 * category.c, category.h (word_boundary_p):
7059 * category.h (CHAR_HAS_CATEGORY):
7060 Use bool for booleans, instead of int.
7062 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7064 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7066 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7068 On assertion failure, print backtrace if available.
7069 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7070 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7071 * Makefile.in (LIB_EXECINFO): New macro.
7074 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7075 * bytecode.c (exec_byte_code):
7076 * callint.c (check_mark, Fcall_interactively):
7077 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7078 (getenv_internal, sync_process_alive, call_process_exited):
7079 * lisp.h (USE_SAFE_ALLOCA):
7080 Use bool for booleans, instead of int.
7081 * lisp.h, process.h: Adjust prototypes to match above changes.
7082 * callint.c (Fcall_interactively): Don't assume the mark's
7083 offset fits in 'int'.
7085 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7087 * buffer.c, buffer.h: Use bool for boolean.
7088 * buffer.c (reset_buffer_local_variables)
7089 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7090 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

7093 (report_overlay_modification, call_overlay_mod_hooks):
7094 (mmap_enlarge, mmap_set_vars):
7095 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7096 Use bool for booleans, instead of int.
7097 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7098 since the 1-or-0 return value is always ignored anyway.
7099 (mmap_initialized_p):
7100 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7101 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7103 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7105 * bidi.c: Use bool for boolean.
7106 This is a bit more readable, and makes the text segment of bidi.o
7107 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7108 Presumably it's faster too.
7109 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7111 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7112 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7113 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7114 (bidi_explicit_dir_char, bidi_level_of_next_char)
7115 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7116 Use bool for booleans, instead of int.
7117 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7118 (bidi_unshelve_cache): Adjust decls to match code.
7120 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7122 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7125 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7127 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7128 * atimer.h: Include <stdbool.h>.
7130 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7132 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7133 compile time tests instead of run time tests on systems that do
7135 (FRAME_MAC_P): Remove leftover from deleted code.
7136 * frame.c (syms_of_frame): Remove leftover from deleted code.
7138 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7140 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7142 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7144 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7145 Otherwise, the compiler complains about (A?B:C) where B is void
7146 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7147 (fontset_add): Return void, for FONTSET_ADD.
7149 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7151 * alloc.c: Use bool for booleans.
7152 (gc_in_progress, abort_on_gc)
7153 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7154 (dont_register_blocks) [GC_MALLOC_CHECK]:
7155 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7156 (check_string_bytes, make_specified_string, memory_full)
7157 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7158 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7159 (mark_stack, valid_pointer_p, make_pure_string)
7160 (Fgarbage_collect, survives_gc_p, gc_sweep):
7161 Use bool for booleans, instead of int.
7162 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7163 Remove unused local.
7164 * alloc.c (PURE_POINTER_P):
7165 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7166 * editfns.c (Fformat):
7167 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7169 * fns.c (sweep_weak_table):
7170 * lisp.h (suppress_checking, push_message, survives_gc_p)
7171 (make_pure_string, gc_in_progress, abort_on_gc):
7172 * lread.c (readchar, read1):
7173 * print.c (Fprin1_to_string):
7174 * xdisp.c (push_message):
7175 Use bool for booleans affected directly or indirectly by
7178 Make recently-introduced setters macros.
7179 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7180 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7181 (set_fontset_default, set_fontset_fallback): Rename from their
7182 upper-case counterparts, and make them functions rather than macros.
7183 This is more consistent with the other recently-introduced setters.
7184 These don't need to be inline, since they're local.
7186 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7188 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7189 the loop (Bug#12247).
7191 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7193 * lisp.h (vcopy): Use memcpy rather than our own loop.
7194 This fixes a performance regression introduced by the recent
7195 addition of vcopy. This means 'vcopy' will need to be modified
7196 for a copying collector, but that's OK. Also, tighten the
7197 checking in the assertion.
7199 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7201 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7202 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7203 non-base glyph for the width of the base character, according to
7204 what x_draw_composite_glyph_string_foreground expects.
7205 Generate WADJUST value according to composition_gstring_width's
7206 expectations, to produce correct width of the composed character.
7207 Reverse the sign of the DU offset produced by ScriptPlace.
7209 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7211 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7213 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7215 Avoid direct writes to contents member of struct Lisp_Vector.
7216 * lisp.h (vcopy): New function to copy data into vector.
7217 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7218 * fns.c (Ffillarray): Use ASET.
7219 * keyboard.c (timer_check_2): Use AREF and ASET.
7220 (append_tool_bar_item, Frecent_keys): Use vcopy.
7221 * lread.c (read_vector): Use ASET.
7222 * msdos.c (Frecent_doskeys): Use vcopy.
7223 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7224 (Finternal_merge_in_global_face): Use ASET and vcopy.
7225 * xfont.c (xfont_list_pattern): Likewise.
7227 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7229 * window.c (Fwindow_point): For the selected window always return
7230 the position of its buffer's point.
7231 (Fset_window_point): For the selected window always go in its
7232 buffer to the specified position.
7234 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7236 Setter macros for fontsets.
7237 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7238 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7239 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7242 2012-08-20 Glenn Morris <rgm@gnu.org>
7244 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7245 Don't assume that `ln -f' works.
7247 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7249 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7250 and later about non-assignments with no effect. See discussion at
7251 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7254 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7256 Inline setter functions for Lisp_Objects slots of struct specbinding.
7257 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7260 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7262 * window.c (select_window): Always make selected window's buffer
7265 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7267 Use AREF and ASET for docstrings of category tables.
7268 * category.h (CATEGORY_DOCSTRING): Use AREF.
7269 (SET_CATEGORY_DOCSTRING): Use ASET.
7270 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7272 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7274 Inline setter functions for hash table members.
7275 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7276 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7277 (set_hash_key_and_value, set_hash_index, set_hash_next)
7278 (set_hash_hash): New functions.
7279 * charset.c, fns.c: Adjust users.
7281 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7283 Inline getter and setter functions for per-buffer values.
7284 * buffer.h (per_buffer_default, set_per_buffer_default)
7285 (per_buffer_value, set_per_buffer_value): New functions.
7286 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7287 * buffer.c, data.c: Adjust users.
7289 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7291 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7293 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7295 Rely on <config.h> + <unistd.h> to declare 'environ',
7296 as gnulib does this if the system doesn't.
7297 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7298 Remove declaration. MS-Windows declares it on stdlib.h which is
7299 included by conf_post.h.
7300 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7301 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

7308 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7310 2012-08-19 Chong Yidong <cyd@gnu.org>

7332 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7333 Return void, not Lisp_Object. Otherwise, the compiler
7334 complains about (A?B:C) where B is void and C is Lisp_Object
7335 when compiling CHAR_TABLE_SET, due to the recent change to
7336 the API of sub_char_table_set_contents.

8166 2012-08-04 Eli Zaretskii <eliz@gnu.org>
8168 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8169 * w32.c (init_environment): Change the default values of many
8170 environment variables in dflt_envvars[] to NULL, to avoid pushing
8171 them into environment when they were not already defined.
8172 Remove the code that deletes site-lisp subdirectories from the default
8173 value of EMACSLOADPATH, as it is no longer needed.
8174 (check_windows_init_file): Now external, not static.
8175 Use Vload_path as is, without adding anything, as this function is now
8176 called when Vload_path is already set up.
8178 * w32.h (check_windows_init_file): Add prototype.
8180 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8181 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8182 compatibility with Posix platforms.
8183 (main): Move the call to check_windows_init_file to here from
8185 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8186 any, in the DEFALT argument into the root of the Emacs build or
8187 installation tree, as appropriate.
8189 * callproc.c (init_callproc_1): Call decode_env_path instead of
8190 doing its equivalent by hand.
8191 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8192 the code that sets Vexec_path run on MS-Windows.
8194 * lread.c (init_lread): Add comments to #ifdef's.
8196 * msdos.c (dos_set_window_size, IT_update_begin)
8197 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
8198 instead of direct references.
8200 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
8202 Export DEFAULT_REHASH_* to GDB.
8203 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
8204 Now constants, not macros.
8206 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8208 Remove unnecessary casts involving pointers.
8209 These casts are no longer needed now that we assume C89 or later,
8210 since they involve casting to or from void *.
8211 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8212 (make_pure_float, make_pure_vector):
8213 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8218 * xdisp.c (x_produce_glyphs):
8219 * xfaces.c (compare_fonts_by_sort_order):
8220 * xfns.c (x_real_positions, select_visual):
8221 * xselect.c (x_stop_queuing_selection_requests)
8222 (x_get_window_property, x_get_window_property_as_lisp_data):
8223 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8224 Remove unnecessary pointer casts.
8225 * alloc.c (record_xmalloc): New function.
8226 * lisp.h (record_xmalloc): New decl.
8227 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8228 more like a function. This is because the pointer cast is not
8229 needed. All uses changed.
8230 * print.c (print_string, print_error_message): Avoid length recalc.
8232 Improve fix for macroexp crash with debugging (Bug#12118).
8233 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8234 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8235 not supposed to be invoked from the garbage collector.
8236 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8237 (gc_aset): New function, which is like ASET but can be
8238 used in the garbage collector.
8239 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
8240 (set_hash_index): Use it instead of ASET.
8242 2012-08-03 Eli Zaretskii <eliz@gnu.org>

8247 (revert_to_self): Forward declarations of static functions.
8248 <static BOOL g_b_init_get_security_info>:
8249 <g_b_init_create_symbolic_link>: New static flags.
8250 (globals_of_w32): Initialize them to zero.
8251 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8252 (map_w32_filename): Improve commentary. Simplify switch.
8253 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8254 headers (most versions of MinGW w32api don't).
8255 (get_security_info, create_symbolic_link)
8256 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8258 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8259 in the argument file name.
8260 (sys_access): Call unc_volume_file_attributes only if
8261 GetFileAttributes fails with network-related error codes.
8262 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8263 have the required privileges.
8264 (get_file_security_desc_by_name): Rename from
8265 get_file_security_desc.
8266 (stat_worker): New function, with most of the guts of 'stat', and
8267 with addition of handling of symlinks and support for 'lstat'.
8268 If possible, get file's attributes and security information by
8269 handle, not by name. Produce S_IFLNK bit for symlinks, when
8270 called from 'lstat'.
8271 (stat, lstat): New functions, call 'stat_worker'.
8272 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8273 symlinks when the underlying filesystem supports them.
8275 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8277 Fix macroexp crash on Windows with debugging (Bug#12118).
8278 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8279 checking subscripts; problem introduced with the recent
8280 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8281 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8282 since it's used in non-static inline functions now.
8284 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8285 Don't assume buffer size fits in 'int'. Remove unused local.
8287 Use C99-style 'extern inline' if available.
8288 * buffer.h (BUFFER_INLINE):
8289 * category.h (CATEGORY_INLINE):
8290 * character.h (CHARACTER_INLINE):
8291 * charset.h (CHARSET_INLINE):

8294 * lisp.h (LISP_INLINE):
8295 * systime.h (SYSTIME_INLINE):
8296 New macro, replacing 'static inline' in this header.
8297 * buffer.h, category.h, character.h, charset.h, composite.h:
8298 * dispextern.h, lisp.h, systime.h:
8299 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8300 * alloc.c (LISP_INLINE):
8301 * buffer.c (BUFFER_INLINE):
8302 * category.c (CATEGORY_INLINE):
8303 * character.c (CHARACTER_INLINE):
8304 * charset.c (CHARSET_INLINE):
8305 * composite.c (COMPOSITE_INLINE):
8306 * dispnew.c (DISPEXTERN_INLINE):
8307 * sysdep.c (SYSTIME_INLINE):
8308 Define to EXTERN_INLINE, so that the corresponding functions
8309 are compiled into code.
8310 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8311 (INLINE_HEADER_END): New macros.
8312 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
8313 since it's used in non-static inline functions now.

8332 hard-coding the path separator.
8334 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8336 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8337 This how ASET and AREF are supposed to work, and makes
8338 it easier to think about future improvements. See
8339 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8340 * charset.h (set_charset_attr): New function.
8341 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
8342 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

8755 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8756 enumeration constants, as PURE and HEAP are too general, and clash
8757 with other headers and sources, such as gmalloc.c and the
8758 MS-Windows system headers. All users changed.
8760 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8762 Revert last save_excursion_save and save_excursion_restore changes.
8763 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8778 complains about the types in the unevaluated arm when the argument
8779 is an integer literal.
8780 (xgetint): Simplify expression.
8781 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8782 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8783 Zaretskii in <http://bugs.gnu.org/12036#13>.
8784 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8785 needed now that we have gdb_make_enums_visible.
8786 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8787 (enum enum_USE_LSB_TAG):
8788 New enum types, packaging up enums that need to be exported to GDB.

8830 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8831 emacs.c, as this is a more-suitable home. Had this been done earlier
8832 the fix for 12036 would have avoided some of the problems noted in
8833 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8834 would have been more obvious.
8835 * emacs.c: Do not include <verify.h>; no longer needed.
8836 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8837 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8838 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8844 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8845 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8846 not be usable in #if. This simplifies things.
8848 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8850 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8855 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8856 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8857 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8858 Adjust to changes in lisp.h and emacs.c, by using
8859 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8860 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8861 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8862 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8863 instead of gdb_valbits.
8864 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8865 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8866 instead of gdb_array_mark_flag.
8867 (xboolvector): Get size from $->size, not $->header.size.
8868 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8869 (xreload, hook-run, hookpost-run): Remove.
8870 * emacs.c: Include <verify.h>.
8871 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8872 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8874 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8875 (gdb_USE_LSB_TAG): New enum constants.
8876 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8877 Also define these as enum constants, so they're visible to GDB.
8878 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8879 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8880 as constants, so they're visible to GDB.

8883 Now enum constants, not macros, so they're visible to GDB.
8884 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8885 more convenient now. All uses changed.
8886 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8887 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8889 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8896 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8897 add argument, tune behavior, and adjust all callers.
8899 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8901 Use typedef for EMACS_INT, EMACS_UINT.
8902 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8903 than macros. This simplifies debugging in the usual case, since
8904 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8905 and it allows expressions involving EMACS_INT casts.
8906 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8908 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8920 Adjust buffer text indirection counters at the end of Fkill_buffer.
8921 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8922 buffer is definitely dead. This should really fix an issue reported
8923 by Christoph Scholtes again. (Bug#12007).
8924 (init_buffer_once): Initialize indirection counters of
8925 buffer_defaults and buffer_local_symbols (for sanity and safety).
8927 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8929 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8930 and continuation glyphs on tooltip frames, leave them at zero.

8958 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8960 Swap buffer text indirection counters in Fbuffer_swap_text.
8961 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8962 This avoids crash reported by Christoph Scholtes at
8963 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8965 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8967 * nsmenu.m (Popdown_data): New struct.
8968 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8970 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

8972 and autorelease them. Also autorelease img and matrix (Bug#12005).
8973 (dealloc): Remove (Bug#12005).
8975 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8977 Adjust consing_since_gc when objects are explicitly freed.

8990 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8992 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8993 as it's limited by the amount of memory, not by INT_MAX.
8995 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8997 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8998 in special-event-map. See the discussion at

9721 * s/aix4-2.h (unix): Remove; no longer needed.
9723 EMACS_TIME simplification (Bug#11875).
9724 This replaces macros (which typically do not work in GDB)
9725 with functions, typedefs and enums, making the code easier to debug.
9726 The functional style also makes code easier to read and maintain.
9727 * systime.h: Include <sys/time.h> on all hosts, not just if
9728 WINDOWSNT, since 'struct timeval' is needed in general.

9741 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9742 not functions. All uses rewritten to use the following, respectively:
9743 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9744 (add_emacs_time, sub_emacs_time): New functions.
9745 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9768 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9769 Prefer snprintf to strncpy.
9770 * nsterm.m (ns_term_init):
9771 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9772 * nsterm.m (ns_term_init):
9773 Avoid the need for strncpy, by using build_string or
9774 make_unibyte_string directly. Use dtoastr, not snprintf.
9775 * process.c (Fmake_network_process): Diagnose service names that
9776 are too long, rather than silently truncating them or creating
9777 non-null-terminated names.
9778 (Fnetwork_interface_info): Likewise, for interface names.
9779 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9780 Prefer sprintf to strncat.

9787 Clarify fallback case.
9789 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

9794 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9795 where argument type is known to be a Lisp_Cons.

9812 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9813 argument, adjust users accordingly. Use build_pure_c_string where

9850 O_RDONLY already includes it).
9852 Stop ns builds setting the EMACSLOADPATH environment variable.
9853 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9854 Now it does not set EMACSLOADPATH, just returns the load-path string.
9855 * nsterm.h: Update accordingly.
9856 * lread.c [HAVE_NS]: Include nsterm.h.
9857 (init_lread) [HAVE_NS]: Use ns_load_path.

9867 (ns_init_paths): Do not set EMACSPATH.

9927 Move marker debugging code under MARKER_DEBUG.
9928 * marker.c (MARKER_DEBUG): Move marker debugging code under
9929 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9930 for bootstrap with --enable-checking (~3x slowdown reported
9931 by Juanma Barranquero <lekktu@gmail.com>).

9942 has no font, use the frame's font. (Bug#11813)
9943 (display_line): Add commentary about displaying truncation glyphs
9945 (produce_special_glyphs): Move here from term.c.
9947 * term.c (produce_special_glyphs): Move to xdisp.c.
9949 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9952 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9954 * xdisp.c (display_line): Avoid warning about implicit declaration
9957 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9959 * lisp.h: Remove empty conditional.
9961 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9963 * lread.c (load_path_check): Now static.
9965 Fix some minor --with-ns problems found by static checking.
9966 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9967 (x_set_font) [!HAVE_X_WINDOWS]:
9968 * image.c (xpm_load_image) [HAVE_NS]:
9969 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9970 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9971 Remove unused local.
9972 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9973 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9974 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9975 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9976 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9977 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9978 Fix pointer signedness problem.
9979 * xfaces.c (FRAME_X_FONT_TABLE):
9980 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9982 2012-07-07 Glenn Morris <rgm@gnu.org>
9984 * lread.c (load_path_check): New function, split from init_lread.
9985 (init_lread): Reorganize. Motivation:
9986 If EMACSLOADPATH is set, check/warn about that rather than the
9987 defaults, which we are not going to use. Hence we can remove
9988 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9989 Don't warn if site-lisp directories are missing.
9990 If not installed, start from a blank load-path, since
9991 PATH_LOADSEARCH refers to the eventual installation directories.
9993 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9995 Support truncation and continuation glyphs on GUI frames, when
9996 fringes are disabled. (Bug#11832)
9997 * xdisp.c (init_iterator): Get dimensions of truncation and
9998 continuation glyphs even if on GUI frames.
9999 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10000 or both, are absent.
10001 (start_display, move_it_in_display_line_to): Handle the case of a
10002 GUI frame without a fringe to display continuation or truncation
10004 (insert_left_trunc_glyphs): Support GUI frames: make sure
10005 truncation glyphs overwrite enough glyphs from the current line to
10006 have sufficient space in pixels.
10007 (display_line): Support truncation and continuation glyphs on GUI
10008 frames. If some spare pixels are left on the line after inserting
10009 the truncation glyphs, fill that space with a stretch glyph of a
10010 suitably computed width.
10012 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10013 produce_glyphs, to support GUI sessions.
10015 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10017 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10019 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10021 Do not require float-time's arg to fit in time_t (Bug#11825).
10022 This works better on hosts where time_t is unsigned, and where
10023 float-time is applied to the (negative) difference between two times.
10024 * editfns.c (decode_time_components): Last arg is now double *,
10025 not int *, and means to store all the result as a double, without
10026 worrying about whether the seconds part fits in time_t.
10027 All callers changed.
10028 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10029 All callers changed.
10030 (Ffloat_time): Do not fail merely because the specified time falls
10031 outside of time_t range.
10033 2012-07-07 Glenn Morris <rgm@gnu.org>
10035 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10036 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10037 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10039 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10041 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10042 Update dependencies.
10044 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10046 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10048 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10049 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10050 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10051 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10052 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10053 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10055 * xfont.c (compare_font_names): Redo to omit the need for casts.
10057 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10059 * xfns.c (Fx_change_window_property): Doc fix.
10060 * w32fns.c (Fx_change_window_property): Doc fix.
10062 * w32fns.c (Fx_window_property): Accept the same arguments as the
10063 X Windows version. Doc fix.
10064 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10066 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10067 Eli Zaretskii <eliz@gnu.org>
10069 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10070 Windows-specific code from nt/config.nt moved here.
10071 Obsolete settings removed.
10073 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10075 * process.c: Avoid unnecessary calls to gettime.
10076 (wait_reading_process_output): Don't get the time of day
10077 when gobbling data immediately and not waiting, as there's no need
10078 for it in that case. This removes a FIXME.
10080 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10082 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10083 is defined (Bug#11768).
10085 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10087 Fix marker debugging code.
10088 * marker.c (byte_char_debug_check): Do not perform the check
10089 if buffer is not multibyte.
10090 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10091 Call byte_char_debug_check with correct arguments.
10093 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10095 Compile marker debugging code only if ENABLE_CHECKING is defined.
10096 * marker.c (byte_char_debug_check, count_markers):
10097 Use only if ENABLE_CHECKING is defined.
10098 (byte_debug_flag): Remove.
10099 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10100 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10102 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10104 Avoid code repetition in marker-related functions.
10105 * marker.c (attach_marker): New function.
10106 (Fset_marker, set_marker_restricted, set_marker_both)
10107 (set_marker_restricted_both): Use it.
10108 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10109 Consistently rename charno to charpos.
10110 (marker_position): Add eassert.
10111 (marker_byte_position): Convert to eassert.
10113 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10115 Simplify list operations in unchain_overlay and unchain_marker.
10116 * buffer.c (unchain_overlay): Simplify. Add comment.
10117 * marker.c (unchain_marker): Simplify. Fix comments.
10119 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10121 Introduce fast path for the widely used marker operation.

10124 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10125 * composite.c (autocmp_chars): Likewise.
10126 * editfns.c (buildmark): Remove.
10127 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10128 (save_restriction_save): Use build_marker.
10129 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10130 * window.c (save_window_save): Likewise.
10132 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10134 Do not use Fdelete_overlay in delete_all_overlays
10135 to avoid redundant calls to unchain_overlay.
10136 * buffer.c (drop_overlay): New function.
10137 (delete_all_overlays, Fdelete_overlay): Use it.
10138 * minibuf.c (get_minibuffer): Fix comment.
10140 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10142 Port to OpenBSD 5.1 amd64.
10143 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10144 This is needed for OpenBSD, and should be harmless on all BSD systems.
10145 Also, include <sys/sysctl.h>, as it should be available on all
10146 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10147 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10148 use p_pid member, not kp_proc.pid.
10150 2012-07-06 Glenn Morris <rgm@gnu.org>
10152 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10154 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10156 More xmalloc and related cleanup.
10157 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10158 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
10159 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

10165 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10167 Omit needless casts involving void * pointers and allocation.
10168 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10169 as the former is more robust if P's type is changed.
10170 Prefer xzalloc to xmalloc + memset 0.
10171 Simplify malloc-or-realloc to realloc.
10172 Don't worry about xmalloc returning a null pointer.
10173 Prefer xstrdup to xmalloc + strcpy.
10174 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10176 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10177 alloca of a constant.
10179 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10181 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10182 hscroll is larger than the line width. Fixes long and futile
10183 looping inside extend_face_to_end_of_line (on a TTY) producing
10184 glyphs that are not needed and thrown away.
10186 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10188 * marker.c (set_marker_restricted_both): Simplify by using
10191 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10193 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10195 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10197 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10198 not defined (Bug#11768).
10199 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10200 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10201 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10202 followed by gtk_box_set_homogeneous (Bug#11768).
10203 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10204 (update_theme_scrollbar_width, xg_create_scroll_bar):
10205 Use gtk_scrollbar_new (Bug#11768).
10206 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10207 (is_box_type): New function (Bug#11768).
10208 (xg_tool_item_stale_p): Call is_box_type.
10209 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10210 with default display (Bug#11768).
10212 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10214 * xdisp.c (window_hscroll_limited): New function.
10215 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10216 coordinates when window's hscroll is set to insanely large
10217 values. (Bug#11857)
10219 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10221 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
10222 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

10280 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10282 * fileio.c (time_error_value): Check the right error number.
10283 Problem reported by Troels Nielsen in
10284 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10286 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10288 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10289 This should be fixed in a better way; see Eli Zaretskii in
10290 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10291 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10293 * fileio.c (time_error_value): Rename from special_mtime.
10294 The old name's problems were noted by Eli Zaretskii in
10295 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10297 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10298 This variable's comment says Emacs needs at least one GDB-visible
10299 symbol of type enum pvec_type, to work around GDB problems.
10300 The symbol's value doesn't matter.
10302 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10303 that causes compilation to fail on pre-C99 compilers.
10305 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10307 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10308 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10310 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10312 * buffer.c (init_buffer_once): Fix initialization of
10313 headers for buffer_defaults and buffer_local_symbols.
10314 Reported by Juanma Barranquero <lekktu@gmail.com>.
10316 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10318 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10319 * lisp.h (enum pvec_type): Use fewer bits.
10320 (PSEUDOVECTOR_SIZE_BITS): New constant.
10321 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10322 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10323 change in pvec_type.
10324 (PSEUDOVECTOR_TYPEP): New macro.
10325 (TYPED_PSEUDOVECTORP): Use it.
10326 * fns.c (internal_equal): Adapt code to extract pvectype.
10327 * emacs.c (gdb_pvec_type): Update type.
10328 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10329 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10330 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10331 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10332 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10333 abusing vector->header.next.nbytes.
10334 (live_vector_p): Use PVEC_TYPE.
10335 (mark_object): Adapt code to extract pvectype. Use switch.
10337 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10339 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10340 Tighten new eassert a bit.
10342 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10344 Fix compilation with --enable-gcc-warnings and -O1
10345 optimization level.
10346 * doprnt.c (doprnt): Change type of tem to int, initialize
10347 to avoid compiler warning. Add eassert.
10348 * search.c (simple_search): Initialize match_byte to avoid
10349 compiler warning. Add eassert.
10351 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10353 Avoid weird behavior with large horizontal scrolls.
10354 Without this change, for example, large hscroll values would
10355 mess up Emacs's display on Fedora 15 x86, presumably due to
10356 overflows in int calculations in the display code.
10357 Also, if buffers had long lines, Emacs would freeze.
10358 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10359 (set_window_hscroll): New function, containing the old guts of
10360 Fset_window_hscroll. Return the clipped value.
10361 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10362 This avoids the need to check against PTRDIFF_MAX.
10364 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10366 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10368 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10370 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10372 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10373 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10374 since GCC 4.4.6 issues a bogus warning for them.
10376 Fix bugs in file timestamp newness comparisons.
10377 * fileio.c (Ffile_newer_than_file_p):
10378 * lread.c (Fload): Use full timestamp resolution of files,
10379 not just the 1-second resolution, so that files that are only
10380 slightly newer still count as newer.
10381 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10382 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10384 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10386 * fileio.c: Improve handling of file time marker. (Bug#11852)
10387 (special_mtime): New function.
10388 (Finsert_file_contents, Fverify_visited_file_modtime):
10389 Use it to set special mtime values consistently.
10391 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10393 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10394 marker for non-existing file. (Bug#11852)
10396 2012-07-03 Glenn Morris <rgm@gnu.org>
10398 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10399 and did not make it into globals.h).
10401 2012-07-03 Tom Tromey <tromey@redhat.com>
10403 * window.c (Fset_window_margins, Fset_window_fringes)
10404 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

10437 * xterm.h: Remove EXFUN.
10439 2012-07-03 Glenn Morris <rgm@gnu.org>
10441 * lisp.h (Frandom): Make it visible to C.
10442 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10443 buffer for invisible buffers. (Bug#1229)
10445 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10447 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10448 values which aren't power of 2.
10449 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10450 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10453 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10455 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10457 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10459 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10461 * alloc.c (allocate_vector_block): Remove redundant
10462 calls to mallopt if DOUG_LEA_MALLOC is defined.
10463 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10464 avoid calls to mallopt if zero_vector is returned.
10466 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10468 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10469 is enabled, avoid dereferencing NULL current_sblock if
10472 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10474 Cleanup basic buffer management.
10475 * buffer.h (struct buffer): Change layout to use generic vector
10476 marking code. Fix some comments. Change type of 'clip_changed'
10477 to bitfield. Remove unused #ifndef old.
10478 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10479 (GET_OVERLAYS_AT): Fix indentation.
10480 (for_each_per_buffer_object_at): New macro.
10481 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10482 (Fbuffer_local_variables): Use it.
10483 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10484 * alloc.c (allocate_buffer): Adjust to match new layout of
10485 struct buffer. Fix comment.
10486 (mark_overlay): New function.
10487 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10488 Lisp area of struct buffer.
10489 (mark_object): Use it. Adjust marking of misc objects
10490 and related comments.
10492 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10494 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10495 wrapper that is not needed because the wrapped code is a no-op (zero
10496 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10497 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10499 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10501 * alloc.c (mark_buffer): Simplify. Remove prototype.
10502 (mark_object): Add comment. Reorganize marking of vector-like
10503 objects. Use CHECK_LIVE for all vector-like objects except buffers
10504 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10505 Avoid redundant calls to mark_vectorlike for bool vectors.
10507 2012-06-30 Glenn Morris <rgm@gnu.org>
10509 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10511 * epaths.in (PATH_SITELOADSEARCH): New.
10512 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10513 This is rather than relying on --enable-locallisppath elements
10514 having "site-lisp" in their names. (Bug#10208#25, 11658)
10516 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10518 * w32proc.c (sys_select): Accept and ignore one more argument.
10520 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10522 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10523 (pselect) [!MS_DOS]: Redirect to sys_select.
10525 * sysdep.c: Don't include dos.h and dosfns.h.
10527 * process.c (sys_select):
10528 * msdos.c (sys_select): Accept one more argument and ignore it.
10530 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10531 adapt data types and code to that.
10534 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10535 which clashes with the gnulib function of the same name.
10537 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10539 * font.c (font_style_to_value, font_style_symbolic)
10540 (font_prop_validate_style): Add type checks for values in
10543 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10545 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10548 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10550 * xdisp.c (try_window_id): Undo last change.
10552 * w32.c (getwd): Adjust commentary about startup_dir.
10553 (init_environment): Always call sys_access, even in non-MSVC
10554 builds. Don't chdir to the directory of the Emacs executable.
10555 This undoes code from 1997 which was justified by the need to
10556 "avoid conflicts when removing and renaming directories". But its
10557 downside was that every relative file name was being interpreted
10558 relative to the directory of the Emacs executable, which can never
10559 be TRT. In particular, it broke sys_access when called with
10560 relative file names.
10561 (sys_access): Map GetLastError to errno.
10563 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10565 * window.h (struct window): Change type of 'fringes_outside_margins'

10567 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10569 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10572 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10574 * gnutls.c (emacs_gnutls_handshake):
10575 Add QUIT to make the loop interruptible.
10577 2012-06-29 Glenn Morris <rgm@gnu.org>
10579 * charset.c (init_charset): Make lack of etc/charsets fatal.
10581 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10583 * editfns.c (region_limit): Fix type mismatch.

10587 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10588 undefined. Convert from xassert to eassert.
10589 * nsmenu.m: Convert from xassert to eassert.
10590 * nsterm.m: Likewise.
10592 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10596 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10598 Avoid integer overflow on scroll-left and scroll-right.
10599 * window.c (HSCROLL_MAX): New macro.
10600 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10601 overflow when requested scroll falls outside ptrdiff_t range.
10603 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10605 * window.h (struct window): Change type of 'hscroll',
10606 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10607 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10608 Adjust users accordingly.
10609 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10610 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10611 from EMACS_INT to ptrdiff_t.
10612 (make_window): Omit redundant initialization.

10631 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10632 adjust comments accordingly.

10753 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10755 Use sprintf return value instead of invoking strlen on result.
10756 In the old days this wasn't portable, since some sprintf
10757 implementations returned char *. But they died out years ago and
10758 Emacs already assumes sprintf returns int.
10759 Similarly for float_to_string.
10760 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10766 * xdisp.c (message_dolog):
10767 * xfns.c (syms_of_xfns):
10768 Use sprintf or float_to_string result to avoid need to call strlen.
10769 * data.c (Fnumber_to_string):
10770 Use make_unibyte_string, since the string must be ASCII.
10771 * lisp.h, print.c (float_to_string): Now returns int length.
10772 * term.c (produce_glyphless_glyph):
10773 Use sprintf result rather than recomputing it.
10775 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10776 * Makefile.in (ALL_CFLAGS):

10806 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10808 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10809 `const char *' to `char *' to avoid compiler warning.
10811 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10813 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10814 instead of truncating it to 63 (admittedly a generous limit).
10816 * process.c: Fix spelling and caps in comments.
10818 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10820 * emacs.c (setpgrp): Remove definition, unused.

10871 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10872 * lisp.h (WAIT_READING_MAX): New macro.
10873 * dispnew.c (Fsleep_for, sit_for):
10874 * keyboard.c (kbd_buffer_get_event):
10875 * process.c (Faccept_process_output):
10876 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10877 This improves on the previous patch, which introduced a bug
10878 when time_t is unsigned and as wide as intmax_t.
10879 See <http://bugs.gnu.org/9000#51>.

10910 language ID in the event parameters.
10912 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10913 event.code, not the obscure "character set ID".
10915 2012-06-23 Chong Yidong <cyd@gnu.org>
10917 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10944 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10946 Support higher-resolution time stamps (Bug#9000).
10947 The time stamps are only nanosecond-resolution at the C level,
10948 since that's the best that any real-world system supports now.
10949 But they are picosecond-resolution at the Lisp level, as that's
10950 easy, and leaves room for future OS improvements.
10952 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10955 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10956 Don't get current time unless it's needed.
10958 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10959 now provides it if it's absent.
10960 (start_atimer): Port to higher-res time stamps.
10961 Check for time stamp overflow. Don't get current time more
10962 often than is needed.
10964 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10965 Include systime.h, not time.h.
10966 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10968 * dired.c: Include stat-time.h.
10969 (Ffile-attributes): File times now have higher resolution.
10971 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10972 (struct image): Timestamp now has higher resolution.
10974 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10975 has at least microseconds now. All uses removed.
10976 (update_frame, update_single_window, update_window, update_frame_1)
10977 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10978 (duration_to_sec_usec): Remove; no longer needed.
10980 * editfns.c (time_overflow): Now extern.
10981 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

10986 (decode_time_components, lisp_seconds_argument): New functions.
10987 (make_time): Now static.
10988 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10989 Report an error if the time is invalid, rather than having the caller
10992 * fileio.c: Include <stat-time.h>
10993 (Fcopy_file): Copy higher-resolution time stamps.
10994 Prefer to set the time stamp via a file descriptor if that works.
10995 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10996 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10997 (Fvisited_file_modtime, Fset_visited_file_modtime):
10998 Support higher-resolution time stamps.
11000 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11002 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11004 * image.c (prepare_image_for_display, clear_image_cache)
11005 (lookup_image): Port to higer-resolution time stamps.
11007 * keyboard.c (start_polling, bind_polling_period):
11008 Check for time stamp overflow.
11009 (read_char, kbd_buffer_get_event, timer_start_idle)
11010 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11011 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11012 Port to higher-resolution time stamps. Do not assume time_t is signed.
11013 (decode_timer): New function. Timers are now vectors of length 9,
11014 not 8, to accommodate the picosecond component.
11015 (timer_check_2): Use it.
11017 * nsterm.m (select_timeout, timeval_subtract): Remove.
11018 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11019 as they're a bit more accurate and handle overflow better.
11020 (ns_select): Change prototype to be compatible with pselect.
11021 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11022 * nsterm.h (ns_select): Adjust prototype.
11024 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11025 us-resolution time stamps.
11026 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11028 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11030 * lisp.h (time_overflow): New decl.
11031 (wait_reading_process_output): First arg is now intmax_t, not int,
11032 to accommodate larger waits.
11034 * process.h (struct Lisp_Process.read_output_delay):
11035 Now counts nanoseconds, not microseconds.
11036 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11038 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11039 (wait_reading_process_output):
11040 Port to ns-resolution time stamps.
11041 (Faccept_process_output, wait_reading_process_output):
11042 Check for time stamp overflow. Do not assume time_t is signed.
11043 (select_wrapper): Remove; we now use pselect.
11044 (Fprocess_attributes): Now generates ns-resolution time stamps.
11046 * sysdep.c: Include utimens.h. Don't include utime.h
11047 or worry about struct utimbuf; gnulib does that for us now.
11048 (gettimeofday): Remove; gnulib provides a substitute.
11049 (make_timeval): New function.
11050 (set_file_times): Now sets ns-resolution time stamps.
11051 New arg FD; all uses changed.
11052 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11053 (system_process_attributes):
11054 Now returns ns-resolution time stamp. All uses changed.
11055 Check for time stamp overflow.
11057 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11058 provides a substitute now.
11060 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11061 since it guarantees struct timespec.
11062 (EMACS_TIME): Now struct timespec, so that we can support
11063 ns-resolution time stamps.
11064 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11065 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11066 (EMACS_USECS): Remove.
11067 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11068 so multiply the arg by 1000 before storing it.
11069 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11071 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11072 Port to ns-resolution time stamps.
11073 (EMACS_TIME_NEG_P): Remove; replaced by....

11076 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11077 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11078 (make_timeval, make_lisp_time, decode_time_components): New decls.
11079 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11080 that it mishandled time_t overflow. You can't compare by subtracting!
11081 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11082 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11084 * term.c: Include <sys/time.h>.
11085 (timeval_to_Time): New function, for proper overflow wraparound.
11086 (term_mouse_position, term_mouse_click): Use it.
11088 * undo.c (record_first_change): Support higher-resolution time stamps
11089 in the undo buffer.
11090 (Fprimitive_undo): Use them when restoring time stamps.
11092 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11093 (w32_get_internal_run_time):
11094 Port to higher-resolution Emacs time stamps.
11095 (ltime): Now accepts single 64-bit integer, as that's more convenient
11098 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11100 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11101 for compatibility with pselect. Support ns-resolution time stamps.
11103 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11105 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11106 Check for time stamp overflow, and support ns-resolution time stamps.
11108 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11109 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11110 (timeval_subtract): Remove; no longer needed.
11111 (XTflash, XTring_bell, x_wait_for_event):
11112 Port to ns-resolution time stamps. Don't assume time_t is signed.
11114 2012-06-22 Chong Yidong <cyd@gnu.org>

11118 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11120 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11121 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11122 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11123 staticidx goes up to 1597 out of 1600 = 0x640.)
11125 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11127 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11139 access to `contents' member of Lisp_Vector objects with AREF and ASET
11142 2012-06-19 Chong Yidong <cyd@gnu.org>
11144 * frame.c (delete_frame): When selecting a frame on a different
11145 text terminal, do not alter the terminal's top-frame.

11148 frame's selected window and its terminal's top-frame.
11149 (unwind_format_mode_line): Restore them.
11150 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11152 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11153 since tty frames can be explicitly named.
11154 (prepare_menu_bars): Likewise.
11156 * term.c (Ftty_top_frame): New function.
11158 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11161 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11162 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11163 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in

11171 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11173 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11174 gets killed during executing of this function (Bug#11665).
11175 Try to always return Qt when the buffer has been actually killed.
11176 (Vkill_buffer_query_functions): In doc-string say that functions
11177 run by this hook should not change the current buffer.
11179 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11181 Fix recently-introduced process.c problems found by static checking.
11182 * process.c (write_queue_push, write_queue_pop, send_process):
11183 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11184 (write_queue_pop): Fix pointer signedness problem.
11185 (send_process): Remove unused local.
11187 2012-06-17 Chong Yidong <cyd@gnu.org>

11201 * lisp.h (eassert): Assume C89 or later.
11202 This removes the need for CHECK.
11203 (CHECK): Remove. Its comments about always evaluating its
11204 argument were confusing, as 'eassert' typically does not evaluate
11207 * coding.c (produce_chars): Use ptrdiff_t, not int.
11209 * xterm.c (x_draw_underwave): Check for integer overflow.
11210 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11384 * alloc.c (make_number) [!defined make_number]:
11385 Remove, as lisp.h always defines this now.

11392 USE_LSB_TAG now is always defined to be either 0 or 1.
11394 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11395 code works fine either way, and efficiency is not a concern here,
11396 as the union type is for debugging, not for production.
11397 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11398 Use an inline function on all platforms when using the union type,
11399 since this is simpler and 'static inline' can be used portably

11506 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11508 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11510 * alloc.c (allocate_vectorlike): Fix last change.
11512 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11514 Block-based vector allocation of small vectors.

11516 adjust comment accordingly.
11517 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11518 to denote vector blocks. Adjust users (live_vector_p,

11541 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11543 * doprnt.c (doprnt): Truncate multibyte char correctly.
11544 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11545 would mishandle a string argument "Xc" if X was a multibyte
11546 character of length 2: it would truncate after X's first byte
11547 rather than including all of X.
11549 2012-06-06 Chong Yidong <cyd@gnu.org>
11551 * buffer.c (word_wrap): Doc fix.

11579 position is past the end of the mode line string.
11581 * buffer.c (buffer_local_value_1): New function, split from
11582 Fbuffer_local_value; can return Qunbound.
11583 (Fbuffer_local_value): Use it.
11584 (Vmode_line_format): Docstring tweaks.

11598 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11600 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11601 Convert pctcpu and pctmem to Lisp float properly.
11602 Let the compiler fold better, as 100.0/0x8000 is exact.
11604 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11606 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11609 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11613 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11615 For a 'struct window', replace some Lisp_Object fields to
11616 bitfields where appropriate, remove unused fields.
11617 * window.h (struct window): Remove unused 'last_mark_x' and
11618 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11619 change its type from Lisp_Object to bitfield.
11620 Change type of 'force_start', 'optional_new_start',
11621 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

11626 Pacify gcc -Wdouble-precision when using Xaw.
11627 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11628 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11629 Use 'float' consistently, rather than 'float' in most places
11630 and 'double' in a couple of places.
11632 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11634 * xdisp.c (handle_stop): Detect whether we have overlay strings
11635 loaded by testing it->current.overlay_string_index to be
11636 non-negative, instead of checking whether n_overlay_strings is
11637 positive. (Bug#11587)
11639 2012-05-31 Chong Yidong <cyd@gnu.org>
11641 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11647 * search.c (search_buffer): Remove calls to
11648 r_alloc_inhibit_buffer_relocation, as it is now called by
11649 maybe_unify_char, which was the cause of relocation of buffer text
11652 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11654 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11655 for the duration of call to load_charset, to avoid problems with
11656 callers of maybe_unify_char that access buffer text through C
11659 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11660 decrement the inhibition flag, instead of just setting or
11663 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11665 Remove obsolete '#define static' cruft.
11666 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11667 This #undef was "temporary" in 2000; it is no longer needed
11668 now that '#define static' has gone away.
11669 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11670 (gray_bitmap_bits): Remove; no longer needed.
11671 All uses replaced with definiens.

11683 (safe_bcopy): Remove decl; no longer has that name.
11684 (main): Coalesce #if into single bit of code, for simplicity.
11685 Cast pointers to uintptr_t, since standard libraries want integers

11714 Do not create empty overlays with the evaporate property (Bug#9642).
11715 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11716 Bug#9642, but explicitly check that the buffer the overlay would
11717 be moved to is live and rearrange lines to make sure that errors
11718 will not put the overlay in an inconsistent state.
11719 (Fdelete_overlay): Cosmetics.
11721 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11723 * w32term.c (my_bring_window_to_top): New function.
11724 (x_raise_frame): Use handle returned by DeferWindowPos, which

11737 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11738 This avoids undefined behavior that might cause the eassert
11739 to not catch an out-of-range value.
11741 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11743 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11758 Only r_alloc_inhibit_buffer_relocation needed to be added;
11759 the others were already declared.
11761 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11762 before checking whether it's out of range. Put the check inside
11764 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11766 2012-05-27 Ken Brown <kbrown@cornell.edu>
11768 * callproc.c (Fcall_process): Restore a line that was accidentally
11769 commented out in the 2011-02-13 change (bug#11547).
11771 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11773 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11774 defined on ralloc.c.
11776 * buffer.c [REL_ALLOC]: Remove prototypes of
11777 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11778 they are now on lisp.h.
11780 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11782 * search.c (search_buffer): Use it to inhibit relocation of buffer
11783 text while re_search_2 is doing its job, because re_search_2 is
11784 passed C pointers to buffer text. (Bug#11519)
11786 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11787 Update value to 24.
11789 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11790 state after an additional call to move_it_in_display_line_to, keep
11791 the values of it->max_ascent and it->max_descent found for the
11793 (pos_visible_p): Revert the comparison against bottom_y to what it
11794 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11797 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11799 Fix coding-related core dumps with gcc -ftrapv.
11800 The code was computing A - B, where A and B are pointers, and B is
11801 random garbage. This can lead to core dumps on platforms that
11802 have special pointer registers, and it also leads to core dumps on
11803 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11804 A - B only when B is initialized properly.
11805 * coding.c (coding_set_source, coding_set_destination): Return void.
11806 (coding_change_source, coding_change_destinations): New functions,
11807 with the old behaviors of coding_set_source and coding_set_destination.
11808 All callers that need an offset changed to use these new functions.
11810 2012-05-26 Glenn Morris <rgm@gnu.org>

11823 (initialize_w32_display): Initialize mouse-highlight data.
11825 * w32inevt.c: Include termchar.h and window.h.
11826 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11827 moves, call note_mouse_highlight. If help_echo changed, call
11828 gen_help_event to produce help-echo message in the echo area.
11829 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11832 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11834 * lread.c (read1): Simplify slightly to avoid an overflow warning
11835 with GCC 4.7.0 on x86-64.
11837 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11839 * bidi.c (bidi_mirror_char): Revert last change: an int is
11840 definitely wide enough here.
11842 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

11856 Use int, not EMACS_INT, where int is wide enough.
11857 (inhibit_garbage_collection, Fgarbage_collect):
11858 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11859 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11860 int might not be wide enough.

11876 (Foverlay_recenter, last_overlay_modification_hooks_used)
11877 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11878 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11879 (validate_region): Omit unnecessary test for b <= e,
11880 since that's guaranteed by the previous test.
11881 (adjust_overlays_for_delete): Avoid pos + length overflow.
11882 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11883 (report_overlay_modification):
11884 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11885 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11886 Omit pointer cast, which isn't needed anyway, and doesn't work
11887 after the EMACS_INT -> ptrdiff_t change.
11888 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11889 * buffer.h: Adjust decls to match defn changes elsewhere.

11891 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11892 Use EMACS_INT, not int, where int might not be wide enough.
11893 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11894 not int, to avoid needless 32-bit limit on 64-bit hosts.
11895 (exec_byte_code): Use tighter memory-full test, one that checks
11896 for alloca overflow. Don't compute the address of the object just
11897 before an array, as that's not portable. Use EMACS_INT, not
11898 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11899 * callint.c (Fcall_interactively):
11900 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11901 * callproc.c (call_process_kill, Fcall_process):
11902 Don't assume pid_t fits into an Emacs fixnum.
11903 (call_process_cleanup, Fcall_process, child_setup):

11911 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11912 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11913 (casify_object): Avoid integer overflow when overallocating buffer.
11914 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11915 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11916 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11917 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11918 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11919 integers are now checked earlier. All uses replaced with XINT.
11921 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11922 For CCL_MapSingle, check that content and value are in int range.

11924 Check that Vcode_version_map_vector is a vector.
11925 (resolve_symbol_ccl_program): Check that vector header is in range.
11926 Always copy the vector, so that we can check its contents reliably
11927 now rather than having to recheck each instruction as it's being
11928 executed. Check that vector words fit in 'int'.
11929 (ccl_get_compiled_code, Fregister_ccl_program)
11930 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11931 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11932 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11933 contents are in range.
11934 (Fccl_execute_on_string): Check that status is in range.
11935 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11936 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11937 Accept and return EMACS_INT, not int, because callers can pass values
11938 out of 'int' range.

11944 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11945 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11946 avoid mishandling large integers.
11947 * character.h: Adjust decls to match defn changes elsewhere.
11948 * charset.c (load_charset_map_from_file, find_charsets_in_text)

11955 Remove now-unnecessary CHECK_NATNUMs.
11956 (Fdefine_charset_internal): Check ranges here, more carefully.
11957 Don't rely on undefined behavior with signed left shift overflow.
11958 Don't assume unsigned int fits into fixnum, or that fixnum fits
11959 into unsigned int. Don't require max_code to be a valid fixnum;
11960 that's not true for gb10830 4-byte on a 32-bit host. Allow
11961 invalid_code to be a cons, for the same reason. Require code_offset
11962 to be a character. Avoid int overflow if max_char is close
11964 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11965 this is intended anyway and avoids some undefined behavior.
11966 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11967 INDEX_TO_CODE_POINT, as that's what it expects.
11968 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11969 * charset.h (DECODE_CHAR): Return int, not unsigned;
11970 this is what was intended anyway, and it avoids undefined behavior.
11971 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11972 integer-overflow issues.
11973 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11974 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11975 where the argument is EMACS_INT, and this behavior is not intended.
11976 * chartab.c (Fmake_char_table, Fset_char_table_range)
11977 (uniprop_get_decoder, uniprop_get_encoder):
11978 Don't assume fixnum fits in int.
11979 * cmds.c (move_point): New function, that does the gist of
11980 Fforward_char and Fbackward_char, but does so while checking
11981 for integer overflow more accurately.
11982 (Fforward_char, Fbackward_char): Use it.
11983 (Fforward_line, Fend_of_line, internal_self_insert)
11984 (internal_self_insert):
11985 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12044 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12045 Do not attempt to compute the address of the object just before a

12766 2012-05-14 Glenn Morris <rgm@gnu.org>

12773 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

12776 (report_error, report_error_1, make_hdr, copy_sym)
12777 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12778 Make arguments const char *, not char *, to avoid violations of C
12779 standard and to fix some AIX warnings reported by Gilles Pion.
12781 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12783 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12784 already have overlays loaded.
12785 (handle_single_display_spec): Before returning without displaying
12786 fringe bitmap, synchronize the bidi iterator with the main display
12787 iterator, by calling iterate_out_of_display_property.
12788 (iterate_out_of_display_property): Detect buffer iteration by
12789 testing that it->string is a Lisp string.
12790 (get_next_display_element): When the current object is exhausted,
12791 and there's something on it->stack, call set_iterator_to_next to
12792 proceed with what's on the stack, instead of returning zero.
12793 (set_iterator_to_next): If called at the end of a Lisp string,
12794 proceed to consider_string_end without incrementing string
12795 position. Don't increment display vector index past the end of
12796 the display vector. (Bug#11417)
12797 (pos_visible_p): Don't report a position visible when move_it_to
12798 stopped at the last line of window, which happens to be scanned
12799 backwards by the bidi iteration. (Bug#11464)
12801 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12803 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12804 and right-margin display specs even if the spec is invalid or we
12805 are on a TTY, and thus unable to display on the fringes.
12806 That's because the text with the property will not be displayed anyway,
12807 so we need to signal to the caller that this is a "replacing"
12808 display spec. This fixes display when the spec is invalid or we
12811 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12813 * unexaix.c (make_hdr): Fix typo in prototype.
12814 This bug broke the build on AIX. Problem reported by Gilles Pion.
12816 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12818 * keyboard.c (kbd_buffer_get_event): Read special events also in

12827 * lisp.mk (lisp): Add newcomment.elc.
12829 2012-05-12 Glenn Morris <rgm@gnu.org>
12831 * Makefile.in (MKDIR_P): New, set by configure.
12832 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12834 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12836 Remove unused function hourglass_started.
12837 * dispextern.h (hourglass_started):
12838 * w32fns.c (hourglass_started):
12839 * xdisp.c (hourglass_started): Remove.
12841 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12843 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12844 Update dependencies.
12846 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12848 * xgselect.c (xg_select): Put maxfds+1 into a var.
12849 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12851 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12853 2012-05-10 Dave Abrahams <dave@boostpro.com>
12855 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12856 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12858 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12860 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12861 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12862 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12863 Initialize xd_registered_buses.
12865 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12867 Untag more efficiently if USE_LSB_TAG.
12868 This is based on a proposal by YAMAMOTO Mitsuharu in
12869 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12870 For an admittedly artificial (nth 8000 longlist) benchmark on
12871 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12872 Emacs's overall text size by 1%.
12873 * lisp.h (XUNTAG): New macro.
12874 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12875 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12876 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12877 * eval.c (Fautoload):
12878 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12879 * frame.h (XFRAME): Use XUNTAG.
12881 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12882 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12883 Remove unportable assumptions about print widths of types like
12885 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12886 intptr_t when converting between pointer and integer, to avoid GCC
12887 warnings about wrong width.
12889 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12891 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12892 stack for each reader_thread, instead of defaulting to 8MB
12893 determined by the linker. This avoids failures in creating
12894 subprocesses on Windows 7, see the discussion in this thread:
12895 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12897 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12899 Fix up display of the *Minibuf-0* buffer in the mini window.
12900 * keyboard.c (read_char): Don't clear the echo area if there's no
12902 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12903 contents of *Minibuf-0*) if there's no message displayed in its stead.
12905 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12907 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12910 2012-05-06 Chong Yidong <cyd@gnu.org>
12912 * lisp.mk (lisp): Update.
12914 2012-05-05 Jim Meyering <meyering@redhat.com>
12916 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12918 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12920 * data.c (PUT_ERROR): New macro.
12921 (syms_of_data): Use it. Add new error type `user-error'.
12922 * undo.c (user_error): New function.
12923 (Fprimitive_undo): Use it.
12924 * print.c (print_error_message): Adjust print style for `user-error'.
12925 * keyboard.c (user_error): New function.
12926 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12928 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12930 Do not limit current-time-string to years 1000..9999.
12931 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12932 (Fcurrent_time_string): Support any year that is supported by the
12933 underlying localtime representation. Don't use asctime, as it
12934 has undefined behavior for years outside the range -999..9999.
12936 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12938 Fix race conditions involving setenv, gmtime, localtime, asctime.
12939 Without this fix, interrupts could mess up code that uses these
12940 nonreentrant functions, since setting TZ invalidates existing
12941 tm_zone or tzname values, and since most of these functions return
12942 pointers to static storage.
12943 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12944 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12945 Grow the critical sections to include not just invoking
12946 localtime/gmtime, but also accessing these functions' results
12947 including their tm_zone values if any, and any related TZ setting.
12948 (format_time_string): Last arg is now struct tm *, not struct tm **,
12949 so that the struct tm is saved in the critical section.
12950 All callers changed. Simplify allocation of initial buffer, partly
12951 motivated by the fact that memory allocation needs to be outside
12952 the critical section.
12954 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12956 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12957 with RESET_INTERVAL.
12959 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12960 Remove duplicated buffer name initialization.
12962 2012-05-02 Jim Meyering <jim@meyering.net>
12964 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12966 * xfns.c (x_window): Use xstrdup (Bug#11375).
12968 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12970 * xdisp.c (pos_visible_p): If already at a newline from the
12971 display string before the 'while' loop, don't walk back the glyphs
12972 from it3.glyph_row. Solves assertion violation when the display
12973 string begins with a newline (egg.el). (Bug#11367)
12975 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12977 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12980 2012-05-01 Glenn Morris <rgm@gnu.org>
12982 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12983 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12984 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12985 All were removed before 23.1.
12987 * dispnew.c: Remove HAVE_LIBNCURSES test;
12988 it is always true on relevant platforms.
12990 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12991 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12993 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12995 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12997 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12998 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13001 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13003 Do not avoid creating empty evaporating overlays (Bug#9642).
13004 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13005 That is, do not delete an evaporating overlay if it becomes
13006 empty after its bounds are adjusted to fit within its buffer.
13007 This fix caused other problems, and I'm reverting it until we get
13008 to the bottom of them.
13010 2012-04-27 Chong Yidong <cyd@gnu.org>
13012 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13014 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13016 * xdisp.c (pos_visible_p): If the window start position is beyond
13017 ZV, start the display from buffer beginning. Prevents assertion
13018 violation in init_iterator when the minibuffer window is scrolled
13019 via the scroll bar.
13021 * window.c (window_scroll_pixel_based): Likewise.
13023 2012-04-27 Chong Yidong <cyd@gnu.org>
13025 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13027 2012-04-27 Glenn Morris <rgm@gnu.org>
13029 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13030 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13032 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13034 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13035 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13037 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13039 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13040 display element, check also the underlying string or buffer
13041 character. (Bug#11341)
13043 * w32menu.c: Include w32heap.h.
13044 (add_menu_item): If the call to AppendMenuW (via
13045 unicode_append_menu) fails, disable Unicode menus only if we are
13046 running on Windows 9X/Me.
13048 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13050 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13051 (xgetint): Add missing shift for LSB tags.
13053 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13055 * keyboard.c (read_char): Don't wipe echo area for select window
13056 events: These might get delayed via `mouse-autoselect-window'
13059 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13061 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13062 manipulation of :loaded-from data.
13064 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13066 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13067 now a cons (bug#11311).
13069 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13071 Do not create empty overlays with the evaporate property (Bug#9642).
13072 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13073 if it becomes empty after its bounds are adjusted to fit within
13074 its buffer. Without this fix, in a nonempty buffer (let ((o
13075 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13076 yields an empty overlay that has the evaporate property, which is
13077 not supposed to happen.
13079 Fix minor GTK3 problems found by static checking.
13080 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13081 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13082 (struct _EmacsFixedClass, emacs_fixed_get_type):

13085 (emacs_fixed_class_init): Omit unused local.
13086 (emacs_fixed_child_type): Remove; unused.

13088 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13089 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13090 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13091 (EMACS_FIXED_GET_CLASS): Remove; unused.
13092 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13094 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13095 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13097 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13099 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13100 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13101 (__malloc_size_t, __malloc_ptrdiff_t):
13102 Remove. All uses removed, replaced by the definiens if needed,
13103 since we can assume C89 or better now.
13104 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13105 (protect_malloc_state, align, get_contiguous_space)
13106 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

13111 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13112 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13113 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13114 Define using prototypes, not old style.
13115 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13116 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13117 (align): Don't assume that signed integer overflow wraps around.
13118 Omit unused local var.
13119 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

13121 Omit no-longer-needed casts.
13122 (valloc): Use getpagesize, not __getpagesize.
13123 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13124 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13126 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13128 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13130 Move functions from C to Lisp. Make non-blocking method calls
13131 the default. Implement further D-Bus standard interfaces.

13161 (Fdbus_method_return_internal, Fdbus_method_error_internal)
13162 (Fdbus_send_signal, Fdbus_register_service)
13163 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

13176 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
13177 Do not assume ptrdiff_t is the same width as 'int'.
13179 * alloc.c: Handle unusual debugging option combinations.
13180 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13181 since the two debugging options are incompatible.
13182 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13184 (mem_init, mem_insert, mem_insert_fixup):
13185 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

13195 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13196 Use Emacs indenting style more consistently. Avoid some casts.
13197 Use 'double' consistently rather than mixing 'float' and 'double'.
13199 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13201 * sysdep.c (list_system_processes, system_process_attributes):

13236 row, return zero immediately.
13237 (try_cursor_movement): If inside continuation line, don't back up
13238 farther than the first row after the header line, if any.
13239 Don't consider the header-line row as "partially visible", even if
13240 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

13278 New extern decls, to avoid calling undeclared functions.
13279 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13280 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13281 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13282 (NEED_MEM_INSERT): New macro.
13283 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13284 Remove one incorrect comment and fix another.
13286 Fix minor ralloc.c problems found by static checking.

13298 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13299 Remove decls. This fixes an "It stinks!".
13301 * alloc.c (which_symbols): Fix alignment issue / type clash.
13303 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13305 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13306 (struct Lisp_Misc_Any): Likewise.
13307 (struct Lisp_Free): Likewise.
13308 * alloc.c (union aligned_Lisp_Symbol): Define.

13318 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13319 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13320 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13321 * s/netbsd.h, s/sol2-6.h:
13322 Remove definition of GC_MARK_STACK, since the default now works.
13323 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13324 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13325 no longer the default.
13326 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13328 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13330 * lread.c (lisp_file_lexically_bound_p):
13331 Fix hang at ";-*-\n" (bug#11238).
13333 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13335 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13336 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

13347 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13349 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13351 2012-04-11 Daniel Colascione <dancol@dancol.org>
13353 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13354 against is gone. It's better to use vfork now so that when Cygwin
13355 gains a new, working vfork, we use it automatically (bug#10398).
13357 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13375 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13377 * w32.c (w32_delayed_load): Record the full path of the library
13378 being loaded (bug#10424).
13380 2012-04-09 Glenn Morris <rgm@gnu.org>
13382 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13383 not just in the obarray, before snarfing them. (Bug#11036)
13385 * Makefile.in ($(leimdir)/leim-list.el):
13386 Pass EMACS rather than BUILT_EMACS.
13388 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13390 * process.c (make_process):
13391 * process.h: Add integer `gnutls_handshakes_tried' member to

13398 (emacs_gnutls_read): Use new log functions,
13399 `gnutls_handshakes_tried' process member, and
13400 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13401 attempts per process (connection).
13403 2012-04-09 Chong Yidong <cyd@gnu.org>
13405 * eval.c (Fuser_variable_p, user_variable_p_eh)
13406 (lisp_indirect_variable): Functions deleted.
13407 (Fdefvar): Caller changed.
13409 * callint.c (Finteractive, Fcall_interactively):
13410 * minibuf.c (Fread_variable): Callers changed.
13412 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13414 * xdisp.c (set_cursor_from_row): If the display string appears in
13415 the buffer at position that is closer to point than the position
13416 after the display string, display the cursor on the first glyph of
13417 the display string. Fixes cursor display when a 'display' text
13418 property immediately follows invisible text. (Bug#11094)
13420 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13422 composite.c: use 'double' consistently
13423 * composite.c (get_composition_id): Use 'double' consistently
13424 instead of converting 'float' to 'double' and vice versa; this is
13425 easier to understand and avoids a GCC warning.
13427 2012-04-09 Glenn Morris <rgm@gnu.org>
13429 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13430 preparation for dumping it with emacs. (Bug#4789)
13431 (leimdir): New variable.

13451 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13452 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13453 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13454 objects, as mark_maybe_pointer will catch them otherwise.
13455 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13456 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13465 Support building on MS-Windows with libxml2.
13467 * makefile.w32-in (OBJ2): Add xml.$(O).
13468 (GLOBAL_SOURCES): Add xml.c.
13469 ($(BLD)/xml.$(O)): New dependency list.
13471 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13472 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13473 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13474 [!WINDOWSNT]: New macros.
13475 (init_libxml2_functions, libxml2_loaded_p): New functions.
13476 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13477 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13478 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13479 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13481 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13482 Call init_libxml2_functions before calling libxml2 functions.
13483 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13485 * emacs.c: Don't include libxml/parser.h.
13486 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13487 xmlCleanupParser directly.
13489 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13491 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13493 * indent.c (Fvertical_motion): If there is a display string at
13494 point, use it.vpos to compute how many lines to backtrack after
13495 move_it_to point. (Bug#11133)
13497 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13499 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13500 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13501 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13502 macros related to unification of CJK characters. For the details,
13503 see the discussion following the message here:
13504 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13506 2012-04-04 Chong Yidong <cyd@gnu.org>
13508 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13510 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13512 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

13520 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13522 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13523 position we get to after a call to move_it_to fails the
13524 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13525 only if we wind up in a string from display property. (Bug#11063)
13527 * window.c (Fdelete_other_windows_internal): Invalidate the row
13528 and column information about mouse highlight, so that redisplay
13529 restores it after reallocating the glyph matrices. (Bug#7464)
13531 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13532 string comes from a `display' text property, use the buffer
13533 position of that property as if we actually saw that position in
13535 (move_it_by_lines): Remove the assertion that
13536 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13537 violated when there's a before-string at the beginning of a line.
13540 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13542 * xdisp.c (append_space_for_newline): If the default face was
13543 remapped, use the remapped face for the appended newline.
13544 (extend_face_to_end_of_line): Use the remapped default face for
13545 extending the face to the end of the line.
13546 (display_line): Call extend_face_to_end_of_line when the default
13547 face was remapped. (Bug#11068)
13549 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13551 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

13569 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13570 (command_loop_1): Use it; inhibit selection update for
13571 handle-select-window too (Bug#8996).

13575 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13577 2012-03-25 Kenichi Handa <handa@m17n.org>
13579 * dispextern.h (struct glyph): Change the bit length of
13580 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13582 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13584 * s/ms-w32.h (tzname): Include time.h before redirecting to

13589 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13592 * xterm.c (XTread_socket): Only modify handling_signal if
13593 !SYNC_INPUT. (Bug#11080)
13595 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13597 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13598 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13599 when fetching a multibyte character consumes more bytes than
13600 CHAR_BYTES returns, due to unification of CJK characters in
13601 string_char. (Bug#11073)
13603 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13605 * process.c (wait_reading_process_output): Handle pty disconnect
13606 by refraining from sending oneself a SIGCHLD (bug#10933).
13608 2012-03-22 Chong Yidong <cyd@gnu.org>
13610 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13612 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

13639 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13640 that is not from display property, accept the row as a "cursor
13641 row" if one of the string's character has a non-nil `cursor'
13642 property. Fixes cursor positioning when there are newlines in
13643 overlay strings, e.g. in icomplete.el. (Bug#11035)
13645 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13647 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13649 2012-03-12 Chong Yidong <cyd@gnu.org>
13651 * eval.c (inhibit_lisp_code): Rename from
13652 inhibit_window_configuration_change_hook; move from window.c.
13654 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13655 * window.c (run_window_configuration_change_hook)
13656 (syms_of_window): Callers changed.
13658 2012-03-11 Chong Yidong <cyd@gnu.org>

13664 2012-03-10 Chong Yidong <cyd@gnu.org>
13666 * frame.c (other_visible_frames): Don't assume the selected frame
13667 is visible (Bug#10955).
13669 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13671 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13673 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13675 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13676 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13679 2012-03-03 Glenn Morris <rgm@gnu.org>
13681 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13683 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13685 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13686 position past the first glyph_row that ends at ZV. (Bug#10902)
13687 (redisplay_window, next_element_from_string): Fix typos in
13689 (redisplay_window): Pass to move_it_vertically the margin in
13690 pixels, not in screen lines.
13692 2012-03-02 Glenn Morris <rgm@gnu.org>
13694 * buffer.c (buffer-list-update-hook): Doc fix.
13696 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13698 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13699 push_it before setting up the iterator for the first overlay
13700 string, even if we have an empty string loaded.
13701 (next_overlay_string): If there's an empty string on the iterator
13702 stack, pop the stack. (Bug#10903)
13704 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13706 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13707 Suggested by Stefan Monnier in
13708 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13709 * alloc.c (widen_to_Lisp_Object): New static function.
13710 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13711 and widening them to Lisp_Objects. This would work even if
13712 USE_LSB_TAG is defined and wide integers are used, which might
13713 happen in a future version of Emacs.
13715 2012-02-25 Chong Yidong <cyd@gnu.org>
13717 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13720 * xselect.c (Fx_selection_exists_p): Doc fix.

13726 * keyboard.c (process_special_events): Handle all X selection
13727 requests in kbd_buffer, not just the next one (Bug#8869).

13757 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13758 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13759 It's useless in that case, and it can cause problems on hosts
13760 that allocate halves of EMACS_INT values separately.
13761 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13762 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13763 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13764 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13765 it avoids undefined behavior on hosts where shifting right by more
13766 than the word width has undefined behavior.
13768 2012-02-19 Chong Yidong <cyd@gnu.org>
13770 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13771 (Funhandled_file_name_directory, Ffile_name_as_directory)

13813 * window.c (Fdelete_window_internal): Invalidate the mouse
13814 highlight (Bug#9904).

13852 2012-02-07 Glenn Morris <rgm@gnu.org>
13854 * image.c (Fimagemagick_types): Doc fix.
13856 * image.c (imagemagick-render-type): Change it from a lisp object

13892 * character.c (char_width): Return EMACS_INT, not int.
13893 (char_width, c_string_width): Check for overflow when

13920 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

13927 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13928 first 2 arguments are identical. This makes inserting large
13929 output from a subprocess an order of magnitude faster on

14383 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14384 verifies glyph row's hash code--we have just reallocated the

14550 is set, removing the need for VIRT_ADDRESS_VARIES.
14551 (PURE_P): Use a more-efficient implementation that needs just one

14568 behave as if the cursor position were at the window margin.
14570 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14571 and the cursor position is out of bounds, behave as if the cursor
14572 position were at the window margin. (Bug#10075)
14574 2011-11-18 Chong Yidong <cyd@gnu.org>
14576 * window.c (Fwindow_combination_limit): Make first argument

14598 compute_line_metrics.
14599 (compute_line_metrics): Call row_hash, instead of computing the
14602 * dispnew.c (verify_row_hash): Call row_hash for computing the
14603 hash code of a row, instead of duplicating code from xdisp.c.
14605 * dispextern.h (row_hash): Add prototype.
14607 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14609 * frame.c (delete_frame): Don't delete the terminal when the last

14658 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14659 with user-defined heap size. Bump the default size of the temacs

14663 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14664 current_matrix and desired_matrix. (Bug#9990)
14665 (verify_row_hash) [XASSERTS]: New function.

14712 Avoid some portability problems by eschewing 'extern inline' functions.
14713 The trivial performance wins aren't worth the portability hassles; see
14714 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14716 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14782 * xmenu.c (cleanup_widget_value_tree): New function.
14783 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14784 calling free_menubar_widget_value_tree directly (Bug#9830).

14790 (window_box_width, window_box_left, window_box_left_offset)
14791 (window_box_right, window_box_right_offset): Declare extern.
14792 Otherwise, these inline functions do not conform to C99 and
14793 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14794 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14795 * intervals.c (adjust_intervals_for_insertion)

14798 (static_offset_intervals): Remove.
14799 (offset_intervals): Rewrite using the old contents of
14800 static_offset_intervals. The old version didn't conform to C99
14801 because an extern inline function contained a reference to an
14802 identifier with static linkage.

14824 (Fwindow_vscroll): Doc fix.

14868 official. Move initialization of image_cache_refcount and
14869 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15037 (w32font_open_internal, compute_metrics):
15038 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w

15115 * editfns.c: Rewrite current-time-zone so that it invokes
15116 the equivalent of (format-time-string "%Z") to get the time zone name.
15117 This fixes a bug when the time zone name contains characters that
15118 need converting from the system time locale to Emacs internal format.
15119 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15120 that patch fixed format-time-string to do the conversion, but
15121 I forgot to fix current-time-zone.
15122 (format_time_string): New function, containing most of
15123 what Fformat_time_string used to contain.
15124 (Fformat_time_string): Rewrite in terms of format_time_string.
15125 This doesn't change this function's behavior.
15126 (current-time-zone): Rewrite to use format_time_string.
15127 This fixes the bug reported by Michael Schierl in
15128 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15129 Jason Rumney's 2007-06-07 change worked around this bug, but
15131 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15133 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15135 * xdisp.c (start_display): If the character at POS is displayed
15136 via a display vector, reset IT->current.dpvec_index to zero.
15137 (try_window_reusing_current_matrix): If a line ends in a display
15138 vector or the next line starts in a display vector, continue
15139 redrawing the window even though the character position of
15140 start_row was reached.
15143 2011-10-18 Chong Yidong <cyd@gnu.org>
15145 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15146 with nobreak-char-display too.
15148 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15150 Fix part 3 of bug#9771.
15151 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15152 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15153 non-neutral characters if the current character is a paragraph
15154 separator (a.k.a. Newline). This avoids running the same
15155 expensive loop twice, once when we consume the preceding newline
15156 and the other time when the line actually needs to be displayed.
15157 Avoid the loop when we see neutrals on the base embedding level
15158 following a character whose directionality is the same as the
15159 paragraph's. This avoids running the expensive loop when a line
15160 ends in a long sequence of neutrals, like control characters.
15161 Add assertion against STRONG_AL type. Slightly rearrange code
15162 that determines the type of a neutral given the first non-neutral
15164 (bidi_level_of_next_char): Set next_en_pos to zero when
15165 invalidating its info.
15167 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15169 * xdisp.c (push_display_prop): Determine whether to record string
15170 or buffer position by IT->string, not by IT->method. Allow
15171 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15172 (move_it_vertically_backward): Don't look for character position
15173 immediately after the newline when in a continuation line.
15176 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15178 * window.c (coordinates_in_window): Rewrite and delabelize
15179 vertical border check. (Bug#5357) (Bug#9618)
15181 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15183 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15184 errors in XSetWindowBorder (bug#9310).
15186 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15188 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15189 avoid crash when xmalloc overrun checking is enabled.
15191 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15193 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15194 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15195 cursor motion with <left> and <right> arrow keys.
15197 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15198 some callers set that themselves.
15200 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15202 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15203 display string and the previous row comes from the same string and
15204 is empty. (Bug#9739) (Bug#9738)
15206 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15208 * doc.c (get_doc_string): Encode file name (bug#9735).
15210 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15212 * bidi.c (bidi_level_of_next_char):
15213 * xdisp.c (get_visually_first_element): Remove old incorrect
15214 comments regarding the Unicode Line Separator character.
15216 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15218 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15220 * alloc.c (Fgc_status): Do not access beyond zombies array
15221 boundary if nzombies > MAX_ZOMBIES.
15222 * alloc.c (dump_zombies): Add missing format specifier.
15224 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15226 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15227 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15229 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15230 Some packages use them to denote characters with modifiers.
15232 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15234 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15235 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15236 matching a pp-number. Rename parameter var to var1.
15238 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15240 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15242 2011-10-08 Glenn Morris <rgm@gnu.org>
15244 * callint.c (Fcall_interactively): Give a more explicit error for the
15245 'c' case with a non-character input. (Bug#8479)
15247 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15249 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15251 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15252 lines that are hscrolled on the left.
15254 * dispnew.c (buffer_posn_from_coords): Account for a possible
15255 presence of header-line. (Bug#4426)
15257 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15259 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15260 Don't advertise functionality which we discourage or doesn't work.
15262 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15264 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15265 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15266 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15267 this makes Emacs dump core during garbage collection on rare
15268 occasions. sizeof is obviously inferior to offsetof here, so
15269 stick with offsetof.
15270 (GC_POINTER_ALIGNMENT): New macro.
15271 (mark_memory): Omit 3rd (offset) arg; caller changed.
15272 Don't assume EMACS_INT alignment is the same as pointer alignment.
15274 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15276 * keyboard.c (read_key_sequence_remapped): New var.
15277 (read_key_sequence): Compute remapping in the right buffer.
15278 (command_loop_1): Use read_key_sequence's remapping directly.
15280 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15282 * dired.c (file_name_completion): Don't expand file name.
15283 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15284 before checking file name handler.
15286 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15287 they've been requested explicitly (bug#9591).
15289 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15291 * keymap.c (Fsingle_key_description): Use make_specified_string
15292 instead of build_string to build string from push_key_description.
15295 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15297 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15298 This fixes a Y2038 bug on 64-bit hosts.
15299 * buffer.c (reset_buffer):
15300 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15301 (Fclear_buffer_auto_save_failure):
15302 Use 0, not -1, to represent an unset failure time, since time_t
15303 might not be signed.
15305 Remove dependency on glibc malloc internals.
15306 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15307 Move back here from lisp.h, but with their new implementations.
15308 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15309 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15310 * charset.c (charset_table_init): New static var.
15311 (syms_of_charset): Use it instead of xmalloc. This removes a
15312 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15313 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15314 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15315 Move back to alloc.c.
15316 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15317 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15319 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15321 * nsterm.m (windowDidResize): Call x_set_window_size only when
15322 ns_in_resize is true. Otherwise set pixelwidth/height and
15323 call change_frame_size (Bug#9628).
15325 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15327 Port --enable-checking=all to Fedora 14 x86-64.
15328 * charset.c (syms_of_charset): Also account for glibc malloc's
15329 internal overhead when calculating the initial malloc maximum.
15331 Port --enable-checking=all to Fedora 14 x86.
15332 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15334 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15335 (overrun_check_realloc, overrun_check_free):
15336 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15337 That way, xmalloc returns a properly-aligned pointer even if
15338 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15339 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15340 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15341 into account when calculating the initial malloc maximum.
15342 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15343 Move here from alloc.c, so that charset.c can use it too.
15344 Properly align; the old code wasn't right for common 32-bit hosts
15345 when configured with --enable-checking=all.
15346 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15347 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15349 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15351 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15354 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15356 * xdisp.c (compute_display_string_end): If there's no display
15357 string at CHARPOS, return -1.
15359 * bidi.c (bidi_fetch_char): When compute_display_string_end
15360 returns a negative value, treat the character as a normal
15361 character not covered by a display string. (Bug#9624)
15363 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15365 * lread.c (Fread_from_string): Fix typo in docstring.
15367 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15369 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15370 newline, reseat the iterator instead of bidi-iterating there one
15371 character at a time. (Bug#9610)
15372 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15373 TO_CHARPOS if the bidi iterator is at base embedding level.
15375 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15377 * lread.c (readevalloop): Use correct code for NBSP.
15378 (read1): Likewise. (Bug#9608)
15380 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15382 * dbusbind.c (Fdbus_register_signal): When service is not
15383 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15385 2011-09-25 Glenn Morris <rgm@gnu.org>
15387 * buffer.c (truncate-lines): Doc fix.
15389 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15391 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15392 (Fset_window_next_buffers): Doc fix.
15394 2011-09-24 Glenn Morris <rgm@gnu.org>
15396 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15398 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15400 Fix minor problems found by static checking.
15401 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15402 * indent.c (Fvertical_motion): Fix == vs = typo.
15404 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15406 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15407 Default value is now t. Doc fix.
15409 * indent.c (Fvertical_motion): Compute and apply the overshoot
15410 logic when moving up, not only when moving down. Fix the
15411 confusing name and values of the it_overshoot_expected variable;
15412 logic changes accordingly. (Bug#9254) (Bug#9549)
15414 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15415 CHARPOS is covered by a display string which includes newlines.
15416 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15417 is covered by a display string with embedded newlines.
15419 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15421 * dbusbind.c (Fdbus_register_signal): Add match rule to
15422 Vdbus_registered_objects_table. (Bug#9581)
15423 (Fdbus_register_method, Vdbus_registered_objects_table):
15426 2011-09-24 Jim Meyering <meyering@redhat.com>
15428 do not ignore write error for any output size
15429 The previous change was incomplete.
15430 While it makes emacs --batch detect the vast majority of stdout
15431 write failures, errors were still ignored whenever the output size is
15432 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15433 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15434 && echo FAIL: ignored write error
15435 FAIL: ignored write error
15436 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15437 && echo FAIL: ignored write error
15438 FAIL: ignored write error
15439 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15441 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15443 * emacs.c (Fkill_emacs): In noninteractive mode exit
15444 non-successfully if a write error occurred on stdout. (Bug#9574)
15446 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15448 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15451 * dispextern.h (struct it): Update the comment documenting what
15454 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15456 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15457 a display string, extend search for cursor position to end of row.
15458 (find_row_edges): If the row ends in a newline from a display
15459 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15460 Handle the case of a display string with multiple newlines.
15461 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15462 non-empty line. Fixes confusing cursor motion with arrow keys at
15463 the beginning of a line that starts with whitespace.
15465 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15467 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15470 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15472 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15473 boolean (Bug#9154).
15475 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15477 * xdisp.c (display_line): Record maximum and minimum buffer
15478 positions even if no glyphs were produced (e.g., by a zero-width
15479 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15480 buffer positions that will be removed from the glyph row because
15482 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15483 column is beyond frame width: don't subtract 1 "pixel" when
15484 computing width of the stretch.
15485 (reseat_at_next_visible_line_start): Undo the change made on
15486 2011-09-17 that saved paragraph information and restored it after
15487 the call to `reseat'. (Bug#9545)
15489 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15491 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15492 and turn window cursor on if cleared (Bug#9415).
15494 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15496 * search.c (boyer_moore): Take unibyte characters from pattern
15497 literally. (Bug#9458)
15499 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15501 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15503 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15505 Fix minor problem found by static checking.
15506 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15507 initialized, to pacify gcc -Wuninitialized.
15509 * fileio.c: Report proper errno when syscall falls.
15510 (Finsert_file_contents): Save and restore errno,
15511 so that report_file_error outputs the correct diagnostic.
15512 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15514 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15516 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15518 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15520 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15521 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15523 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15525 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15526 about the current paragraph and restore it after the call to reseat.
15528 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15529 (bidi_find_paragraph_start): Search back for paragraph beginning
15530 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15531 (bidi_move_to_visually_next): Only trigger paragraph-related
15532 computations when the last character is a newline or at EOB, not
15533 just any NEUTRAL_B. (Bug#9470)
15535 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15536 truncated lines if point is covered by a display string. (Bug#9524)
15538 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15540 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15541 (cons_to_x_long): New function.
15542 (lisp_data_to_selection_data): Use it. Correct the test for
15543 short-versus-long data; it was negated. Break out of vector
15544 loop, for efficiency, when a long datum is discovered.
15546 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15548 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15550 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15552 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15553 GCC PR/17406) by declaring this function with external scope.
15555 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15557 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

15560 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15562 * editfns.c (Fformat): Correctly handle text properties on "%%".
15564 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15566 * xterm.c (x_draw_composite_glyph_string_foreground):
15567 * w32term.c (x_draw_composite_glyph_string_foreground):
15568 * term.c (encode_terminal_code):
15569 * composite.c (composition_update_it, get_composition_id):
15570 * xdisp.c (get_next_display_element)
15571 (fill_composite_glyph_string): Add comments about special meaning
15572 of TAB characters in a composition.
15574 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15576 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15577 This occurs when processing a multibyte format.
15578 Problem reported by Wolfgang Jenker.
15580 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15582 * xdisp.c (try_cursor_movement): Only check for exact match if
15583 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15585 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15587 Remove unused external symbols.
15588 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15589 * xdisp.c (calc_pixel_width_or_height): Now static.
15590 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15591 * indent.c (check_display_width):
15592 * w32term.c: Fix comment to match code.
15593 * xterm.c, xterm.h (x_catching_errors): Remove.
15595 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15597 * xselect.c: Use signed conversions more consistently (Bug#9498).
15598 (selection_data_to_lisp_data): Assume incoming selection data are
15599 signed integers, not unsigned. This is to be consistent with
15600 outgoing selection data, which was modified to use signed integers
15601 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15602 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15603 expects long, not unsigned long.
15605 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15607 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15608 computation of loop end. Reported by Johan Bockgård
15611 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15613 * frame.c (Fother_visible_frames_p): Function deleted.
15615 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15617 * indent.c (compute_motion): Process display vector front to back
15618 rather than the other way around. (Bug#2496)
15620 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15622 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15624 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15626 * minibuf.c (Fread_from_minibuffer): Doc fix.
15628 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15630 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15631 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15633 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15635 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15636 value for non-existent files.
15638 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15640 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15641 set its "size" to -1. This will set the modtime_size field of
15642 the corresponding buffer to -1, which is what
15643 verify-visited-file-modtime expects for files that do not exist.
15646 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15648 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15650 * lisp.h: ... from here. push_key_description is no longer
15651 defined in keyboard.c, so its declaration should not be in
15652 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15653 logically belongs with push_key_description.
15655 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15657 * buffer.h: Include <sys/types.h> instead of <time.h>.
15658 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15659 Problem reported by Herbert J. Skuhra.
15661 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15663 * xml.c (parse_region): Make the parsing work for
15664 non-comment-starting XML files again (bug#9144).
15666 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15668 * image.c (gif_load): Fix calculation of bottom and right corner.
15671 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15673 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15674 redisplay in small windows.
15676 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15678 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15680 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15682 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15683 Operate on live windows only.
15685 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15687 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15689 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15691 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15692 only under bidi iteration.
15694 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15696 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15698 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15700 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15701 Without this fix, the command to link temacs failed due to an
15702 undefined symbol __builtin_isnan. This is because
15703 /usr/include/iso/math_c99.h #defines isnan(x) to
15704 __builtin_isnan(x), but the bundled gcc, which identifies itself
15705 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15707 * floatfns.c (isnan): #undef, and then #define to a clone of
15709 (Fisnan): Always define, since it's always available now.
15710 (syms_of_floatfns): Always define isnan at the Lisp level.
15712 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15714 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15716 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15718 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15719 The previous code assumed that file offsets (off_t values) fit in
15720 EMACS_INT variables, which is not true on typical 32-bit hosts.
15721 The code messed up by falsely reporting buffer overflow in cases
15722 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15723 when "big" contains more than 2**29 bytes, even though this
15724 inserts just one byte and does not overflow the buffer.
15725 (Finsert_file_contents): Store file offsets as off_t
15726 values, not as EMACS_INT values. Check for overflow when
15727 converting between EMACS_INT and off_t. When checking for
15728 buffer overflow or for overlap, take the offsets into account.
15729 Don't use EMACS_INT for small values where int suffices.
15730 When checking for overlap, fix a typo: ZV was used where
15731 ZV_BYTE was intended.
15732 (Fwrite_region): Don't assume off_t fits into 'long'.
15733 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15735 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15737 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15739 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15741 sprintf-related integer and memory overflow issues (Bug#9412).
15743 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15744 (esprintf, exprintf, evxprintf): New functions.
15745 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15746 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15747 (modify_event_symbol): Do not assume that the length of
15748 name_alist_or_stem is safe to alloca and fits in int.
15749 (Fexecute_extended_command): Likewise for function name and binding.
15750 (Frecursion_depth): Wrap around reliably on integer overflow.
15751 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15752 since some callers pass EMACS_INT values.
15753 (Fsingle_key_description): Don't crash if symbol name contains more
15754 than MAX_ALLOCA bytes.
15755 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15756 (get_minibuffer): Arg is now EMACS_INT, not int.
15757 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15758 (esprintf, exprintf, evxprintf): New decls.
15759 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15761 * dbusbind.c (signature_cat): New function.
15762 (xd_signature, Fdbus_register_signal):
15763 Do not overrun buffer; instead, report string overflow.
15765 * dispnew.c (add_window_display_history): Don't overrun buffer.
15766 Truncate instead; this is OK since it's just a log.
15768 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15769 even if the time zone offset is outlandishly large.
15770 Don't mishandle offset == INT_MIN.
15772 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15773 when creating daemon; the previous buffer-overflow check was incorrect.
15775 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15776 which has the guts of the old verror function.
15778 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15779 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15781 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15782 (font_unparse_xlfd): Don't blindly alloca long strings.
15783 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15784 fits in int, when using sprintf. Use single snprintf to count
15785 length of string rather than counting it via multiple sprintfs;
15786 that's simpler and more reliable.
15787 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15788 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15789 sprintf, in case result does not fit in int.
15791 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15792 (fontset_from_font): Print it.
15794 * frame.c (tty_frame_count): Now printmax_t, not int.
15795 (make_terminal_frame, set_term_frame_name): Print it.
15796 (x_report_frame_params): In X, window IDs are unsigned long,
15797 not signed long, so print them as unsigned.
15798 (validate_x_resource_name): Check for implausibly long names,
15799 and don't assume name length fits in 'int'.
15800 (x_get_resource_string): Don't blindly alloca invocation name;
15801 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15804 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15805 (xg_check_special_colors, xg_set_geometry):
15806 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15808 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15809 Use esprintf, not sprintf, in case result does not fit in int.
15811 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15812 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15813 it as a large positive number.
15814 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15815 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15817 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15818 in case result does not fit in int.
15820 * print.c (float_to_string): Detect width overflow more reliably.
15821 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15822 buffer overrun. Don't assume list length fits in 'int'. Treat
15823 print length of 0 as 0, not as infinity; to be consistent with other
15824 uses of print length in this function. Don't overflow print length
15825 index. Don't assume hash table size fits in 'long', or that
15826 vectorlike size fits in 'unsigned long'.
15828 * process.c (make_process): Use printmax_t, not int, to format
15829 process-name gensyms.
15831 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15833 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15834 to avoid potential buffer overrun.
15836 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15837 if X resource line is longer than 512 bytes.
15839 * xfns.c (x_window): Make sprintf buffer a bit bigger
15840 to avoid potential buffer overrun.
15842 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15844 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15846 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15848 Integer overflow fixes for scrolling, etc.
15849 Without these, Emacs silently mishandles large integers sometimes.
15850 For example, "C-u 4294967297 M-x recenter" was treated as if
15851 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15853 * xdisp.c (try_window_id): Check Emacs fixnum range before
15854 converting to 'int'.
15856 * window.c (window_scroll_line_based, Frecenter):
15857 Check that an Emacs fixnum is in range before assigning it to 'int'.
15858 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15859 values converted from Emacs fixnums.
15860 (Frecenter): Don't wrap around a line count if it is out of 'int'
15861 range; instead, treat it as an extreme value.
15862 (Fset_window_configuration, compare_window_configurations):
15863 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15865 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15866 that can exceed INT_MAX. Check that EMACS_INT value is in range
15867 before assigning it to the (possibly-narrower) index.
15868 (match_limit): Don't assume that a fixnum can fit in 'int'.
15870 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15873 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15874 (Fvertical_motion): Don't wrap around LINES values that don't fit
15875 in 'int'. Instead, treat them as extreme values. This is good
15876 enough for windows, which can't have more than INT_MAX lines anyway.
15878 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15880 * Require libxml/parser.h to avoid compilation warning.
15882 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15884 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15885 since this reportedly can destroy thread storage.
15887 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15889 * syntax.c (find_defun_start): Update all cache variables if
15890 exiting early (Bug#9401).
15892 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15894 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15896 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15897 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15898 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15900 * term.c (tty_append_glyph): New function.
15901 (produce_stretch_glyph): Static function and its prototype deleted.
15903 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15906 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15908 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15909 when checking :margin (Bug#9390).
15910 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15911 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15912 so that the name doesn't mislead. All uses changed.
15914 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15916 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15919 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15921 * xdisp.c (move_it_to): Don't bail out early when reaching
15922 position beyond to_charpos, if we are scanning backwards.
15923 (move_it_vertically_backward): When DY == 0, make sure we get to
15924 the first character in the line after the newline.
15926 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15928 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15929 (ccl_driver): Do not generate an out-of-range pointer.
15930 (Fccl_execute_on_string): Remove unnecessary check for
15931 integer overflow, noted by Stefan Monnier in
15932 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15933 Remove a FIXME that didn't need fixing.
15934 Simplify the newly-introduced buffer reallocation code.
15936 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15938 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15940 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15942 Integer and memory overflow issues (Bug#9196).
15944 * doc.c (get_doc_string): Rework so that
15945 get_doc_string_buffer_size is the actual buffer size, rather than
15946 being 1 less than the actual buffer size; this makes xpalloc more
15949 * image.c (x_allocate_bitmap_record, cache_image):
15950 * xselect.c (Fx_register_dnd_atom):
15951 Simplify previous changes by using xpalloc.
15953 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15954 since either will do and ptrdiff_t is convenient with xpalloc.
15956 * charset.c (charset_table_size)
15957 (struct charset_sort_data.priority): Now ptrdiff_t.
15958 (charset_compare): Don't overflow if priorities differ greatly.
15959 (Fsort_charsets): Don't assume list length fits in int.
15960 Check for size-calculation overflow when allocating sort data.
15961 (syms_of_charset): Allocate an initial charset table that is
15962 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15964 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15966 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15967 The actual value is always <= INT_MAX, and leaving it unsigned made
15968 overflow checking harder.
15970 * dispextern.h (struct glyph_matrix.rows_allocated)
15971 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15972 with xpalloc. The values are still always <= INT_MAX.
15974 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15976 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15977 (SAFE_NALLOCA): New macro.
15979 * region-cache.c (struct boundary.pos, find_cache_boundary)
15980 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15981 (set_cache_region, invalidate_region_cache)
15982 (revalidate_region_cache, know_region_cache, region_cache_forward)
15983 (region_cache_backward, pp_cache):
15984 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15985 so that ptrdiff_t * can be passed to xpalloc.
15986 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15987 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15988 (pp_cache): Don't assume cache_len fits in int.
15989 * region-cache.h: Adjust extern decls to match.
15991 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15992 EMACS_INT, since either will do, for xpalloc.
15994 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15995 (xnmalloc, xnrealloc, xpalloc): New functions.
15997 * bidi.c (bidi_shelve_header_size): New constant.
15998 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15999 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16001 * bidi.c (bidi_cache_shrink):
16002 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16004 Don't update size of array until after memory allocation succeeds,
16005 because xmalloc/xrealloc may not return.
16006 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16007 now that we have proper integer overflow checking.
16008 (record_overlay_string, overlay_strings): Catch overflows when
16009 calculating size of overlay_str_buf.
16011 * callproc.c (Fcall_process): Check for size overflow when
16012 calculating size of args2.
16013 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16014 Normally we prefer signed values, but sticking with ptrdiff_t would
16015 require adding more-complicated checks.
16017 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16018 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16019 Redo buffer-overflow calculations to avoid integer overflow.
16020 Add a FIXME comment where memory seems to be over-allocated.
16022 * character.c (Fstring): Check for size-calculation overflow.
16024 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16025 unnecessary integer overflow. Check for size overflow.
16026 (encode_coding_object): Don't update size until xmalloc succeeds.
16028 * composite.c (get_composition_id): Check for overflow in glyph
16029 length calculations.
16031 Integer and memory overflow fixes for display code.
16032 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16033 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16034 (scrolling_window): Check for overflow in size calculations.
16035 (line_draw_cost, realloc_glyph_pool, add_row_entry):

16058 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16060 * emacs.c (main): Do not reallocate argv, since there is a null at
16061 the end that can be overwritten, and this way there's no need to
16062 worry about size-calculation overflow.

16192 (X_LONG_MIN): New macros.
16193 Use them to make the following changes clearer.
16194 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

16196 future maintainers not to raise the value too much later.
16197 (SELECTION_QUANTUM): Remove, replacing with ...
16198 (selection_quantum): ... new function, which avoids overflow.
16200 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16201 assumption that selection length fits in 'int'.

16218 Don't store size until memory allocation succeeds.
16219 (x_get_window_property): Plug memory leak on memory exhaustion.
16220 Don't double-block input; malloc is safe here. Don't assume 2**34
16221 - 4 fits in unsigned long. Add an xassert to check
16222 XGetWindowProperty overflow. Be more careful about overflow
16223 calculations, and distinguish size from memory overflow better.

16230 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16231 result parameters unless successful. Rely on cons_to_unsigned
16232 to report problems with elements; the old code wasn't right anyway.

16267 * lisp.h (hash_lookup, hash_put):
16268 * minibuf.c (Ftest_completion):
16269 Use ptrdiff_t for hash table indexes, not int (which is too
16270 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

16303 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16304 (x_send_scroll_bar_event): Likewise. Check that the size does not
16305 exceed limits imposed by XClientMessageEvent, as well as the usual
16306 ptrdiff_t and size_t limits.

16309 (make_lispy_movement): Use same integer type in forward decl
16310 that is used in the definition.

16312 Change bufsize argument back to int, undoing my 2011-03-30 change.
16313 We prefer signed types, and int is wide enough here.
16314 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16315 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16316 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16317 length, not size_t. Use ptrdiff_t for index, not int.
16318 (keyremap_step, read_key_sequence): Redo bufsize check to avoid

16347 Prefer int to unsigned where either will do.
16348 (tiff_handler): New function, combining the cores of the
16349 old tiff_error_handler and tiff_warning_handler.

16351 stack buffer overflows. It uses only the features of vsnprintf
16352 that are common to both POSIX and native Microsoft.
16353 (tiff_error_handler, tiff_warning_handler): Use it.
16354 (tiff_load, gif_load, imagemagick_load_image):
16355 Don't assume :index value fits in 'int'.

16398 buffers, return left-to-right.
16399 (set_cursor_from_row): Consider candidate row a win if its glyph

16401 positioning on the newline at EOL of R2L text within L2R
16402 paragraph, and vice versa.
16403 (try_cursor_movement): Check continued rows, in addition to
16404 continuation rows. Fixes unwarranted scroll when point enters a
16405 continued line of R2L text within an L2R paragraph, or vice versa.
16406 (cursor_row_p): Consider the case of point being equal to
16407 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16408 from the end of a short line to the beginning of a continued line
16409 of R2L text within L2R paragraph.

16436 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16437 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16438 candidate is selected by the mouse, and that candidate has a
16439 composed character under the mouse.
16441 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16442 coordinates reported by pos-visible-in-window-p for a composed

16452 consider it a hit if to_charpos is anywhere in the range of the
16453 composed buffer positions.
16455 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16457 * image.c (gif_load): Don't assume that each subimage has the same
16458 dimensions as the base image. Handle disposal method that is
16459 "undefined" by the gif spec (Bug#9335).
16461 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

16466 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16468 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16469 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16470 from an Org mode buffer to a Speedbar frame.
16472 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16473 a composition, take its buffer position from IT->cmp_it.charpos.
16474 Fixes cursor positioning at the beginning of a line that begins
16475 with a composed character.
16477 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16479 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16480 character bidirectional type, use STRONG_L instead. Fixes crashes
16481 in a buffer produced by `describe-categories'.
16483 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16484 members before the level stack, so they would be saved and
16485 restored when copying iterator state. Fixes incorrect reordering
16486 around TABs covered by display properties.
16488 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16490 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
16492 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

16495 (internal_condition_case_2, internal_condition_case_n):
16496 Remove unnecessary aborts (Bug#9081).
16498 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16500 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16501 has no `load' handler, try opening the file locally. (Bug#9311)
16503 2011-08-16 Ken Brown <kbrown@cornell.edu>
16505 * gmalloc.c: Expand comment.
16507 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16509 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16510 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

16521 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
16523 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16524 in the static heap.
16525 [CYGWIN] (special_realloc): New function.
16526 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
16527 requests to realloc storage in the static heap.

16540 * dispextern.h: Fix a typo in the comment to bidi_type_t.
16542 * chartab.c: Improve commentary for the uniprop_table API.
16544 * bidi.c (bidi_paragraph_init): Support zero value of
16545 bidi_ignore_explicit_marks_for_paragraph_level.
16546 (bidi_initialize): Use uniprop_table instead of including
16547 biditype.h and bidimirror.h.
16549 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16550 coordinates of the iterator when restoring from ppos_it.
16553 2011-08-14 Kenichi Handa <handa@m17n.org>

16556 after the pid of the process is set to -1 (Bug#8162).
16558 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16560 * xdisp.c (move_it_in_display_line_to): Don't invoke
16561 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16562 ppos_it. Fixes vertical cursor motion when line beginning is
16563 covered by an image. (Bug#9296)
16565 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16567 * nsterm.h (ns_run_ascript): Declare.
16568 (NSAPP_DATA2_RUNASSCRIPT): Define.
16570 * nsfns.m (as_script, as_result, as_status): New static variables.
16571 (ns_run_ascript): New function.
16572 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16573 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16574 the event loop. Get status from as_status (Bug#7276).
16576 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16577 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16578 the event loop (Bug#7276).
16580 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16582 * gnutls.c (QCgnutls_bootprop_priority)
16583 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16584 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16585 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16586 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16587 (QCgnutls_bootprop_verify_hostname_error)
16588 (QCgnutls_bootprop_callbacks_verify): Rename from
16589 Qgnutls_bootprop_..., all uses changed.
16591 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16594 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16596 * xfaces.c (Qframe_set_background_mode): Now static.

16601 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16603 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16604 (Fnetwork_interface_list): Allocate in increments of bytes instead
16605 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16606 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16608 (struct ifflag_def): notrailers is smart on OSX.
16609 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16610 Get hardware address with getifaddrs if available.
16612 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16614 * xdisp.c (iterate_out_of_display_property): xassert that
16615 IT->position is set to within IT->object's boundaries. Break from
16616 the loop as soon as EOB is reached; avoids infloops in redisplay
16617 when IT->position is set up wrongly due to some bug.
16618 Set IT->current to match the bidi iterator unconditionally.
16619 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16620 entry. Force push_it to save on the stack the current
16621 buffer/string position, to be restored by pop_it. Fix flags in
16622 the iterator structure wrt the object coming from a display
16623 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16624 properties. (Bug#9284)
16626 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16628 * fontset.c (fontset_get_font_group): Add proper type checks.
16631 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

16634 and LC_VERSION_MIN_MACOSX.
16635 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16636 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16638 2011-08-08 Eli Zaretskii <eliz@gnu.org>

16641 no-display-properties-and-no-overlays under bidi display.
16642 Set disp_pos in the bidi iterator to avoid searches for display
16643 properties and overlays.
16645 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16647 * editfns.c (Fset_time_zone_rule): Document relationship with the

16651 the font entity extracted from the cache (Bug#8109).
16653 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16655 * composite.c (autocmp_chars): Don't reset point. That is done by
16656 restore_point_unwind (Bug#5984).
16658 2011-08-07 Juri Linkov <juri@jurta.org>
16660 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16661 to show the arg `TIME' instead of `TIMEVAL'.
16663 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16665 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16666 display property strides EOL and includes a newline, as in
16667 longlines-mode. (Bug#9254)
16668 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16669 word-wrap under bidirectional display. (Bug#9224)
16671 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16672 is non-zero, even if the data buffer is NULL. Fixes a crash in
16673 vertical-motion with longlines-mode. (Bug#9254)
16675 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16677 * bidi.c <bidi_cache_total_alloc>: Now static.
16678 (bidi_initialize): Initialize bidi_cache_total_alloc.
16680 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16683 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16684 amount allocated this far in `bidi_cache_total_alloc'.
16685 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16686 non-zero, only free the data buffer without restoring the cache
16687 contents. All callers changed.
16689 * dispextern.h (bidi_unshelve_cache): Update prototype.
16691 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16692 (move_it_in_display_line, move_it_to)
16693 (move_it_vertically_backward, move_it_by_lines): Replace the call
16694 to xfree to an equivalent call to bidi_unshelve_cache.
16695 (move_it_in_display_line_to): Fix logic of returning
16696 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16698 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16700 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16701 came from a string character with a `cursor' property. (Bug#9229)
16703 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16705 * Makefile.in (LIB_PTHREAD): New variable.
16706 (LIBES): Add LIB_PTHREAD (Bug#9216).
16708 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16709 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16711 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16713 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16715 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16717 * xterm.c (x_find_topmost_parent): New function.
16718 (x_set_frame_alpha): Find topmost parent window with
16719 x_find_topmost_parent and set the property there also (bug#9181).
16720 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16722 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16724 * callproc.c (Fcall_process): Avoid vfork clobbering
16725 the local vars buffer, coding_systems, current_dir.
16727 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16729 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16731 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16733 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16734 so that it is not optimized away.
16736 * xdisp.c (compute_display_string_pos): Remove unused local.
16738 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16740 Fix slow cursor motion and scrolling in large buffers with
16741 selective display, like Org Mode buffers. (Bug#9218)
16743 * dispextern.h (struct bidi_it): New member disp_prop_p.
16745 * xdisp.c: Remove one-slot cache of display string positions.
16746 (compute_display_string_pos): Accept an additional argument
16747 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16748 for a display string or property. If found, set DISP_PROP_P
16751 * bidi.c (bidi_fetch_char): Accept an additional argument
16752 DISP_PROP_P, and pass it to compute_display_string_pos.
16753 Only handle text covered by a display string if DISP_PROP_P is returned
16754 non-zero. All callers of bidi_fetch_char changed.
16756 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16758 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16760 2010-12-03 Don March <don@ohspite.net>
16762 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16763 last character M-[char] is translated to ESC [char] (bug#7541).
16765 2011-08-02 Kenichi Handa <handa@m17n.org>
16767 * lisp.h (uniprop_table): Extern it.
16769 * chartab.c (uniprop_table): Make it non-static.
16771 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16773 * xdisp.c (forward_to_next_line_start): Accept additional argument
16774 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16776 (reseat_at_next_visible_line_start): Use the bidi iterator state
16777 returned by forward_to_next_line_start to restore the state of
16778 it->bidi_it after backing up to previous newline. (Bug#9212)
16780 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16782 * regex.c (re_comp): Protoize.
16783 (re_exec): Fix return type.
16784 (regexec): Fix type of `ret'. (Bug#9203)
16786 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16788 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16789 This is needed if max-image-size is a floating-point number.
16791 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16793 * print.c (print_object): Print empty symbol as ##.
16795 * lread.c (read1): Read ## as empty symbol.
16797 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16799 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16800 setting frame foreground color (Bug#9175).
16801 (x_set_background_color): Likewise.
16803 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16804 contents (Bug#9176).
16805 (EmacsTooltip -init): Remove bezels and add shadows to
16808 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16809 or scroll bar (Bug#8470).
16811 * nsfont.m (nsfont_open): Remove assignment to voffset and
16812 unnecessary vars hshink, expand, hd, full_height, min_height.
16813 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16815 * nsterm.h (nsfont_info): Remove voffset field.
16817 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16819 Implement strike-through and overline on NextStep (Bug#8863).
16821 * nsfont.m (nsfont_open): Use underline position provided by font,
16822 instead of hard-coded value of 2.
16823 (nsfont_draw): Call ns_draw_text_decoration instead.
16825 * nsterm.h: Add declaration for ns_draw_text_decoration.
16827 * nsterm.m (ns_draw_text_decoration): New function for drawing
16828 underline, overline, and strike-through.
16829 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16830 ns_draw_text_decoration. Change treatment of cursor drawing to
16831 accommodate underlining, etc.
16833 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16835 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16838 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16840 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16841 Without this fix, if a signal arrives just after memory fills up,
16842 'malloc' might be invoked reentrantly.
16844 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16845 In other words, assume that every image size is allowed, on non-X
16846 hosts. This assumption is probably wrong, but it lets Emacs compile.
16848 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16850 * regex.c (re_iswctype): Convert return values to boolean.
16852 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16854 * xdisp.c (compute_display_string_pos): Don't use cached display
16855 string position if the buffer had its restriction changed.
16858 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16860 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16862 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16864 Integer signedness and overflow and related fixes. (Bug#9079)
16866 * bidi.c: Integer size and overflow fixes.
16867 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16868 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16869 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16870 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16871 (bidi_find_other_level_edge):
16872 Use ptrdiff_t instead of EMACS_INT where either will do.
16873 This works better on 32-bit hosts configured --with-wide-int.
16874 (bidi_cache_ensure_space): Check for size-calculation overflow.
16875 Use % rather than repeated addition, for better worst-case speed.
16876 Don't set bidi_cache_size until after xrealloc returns, because it
16878 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16879 (bidi_cache_ensure_space): Also check that the bidi cache size
16880 does not exceed that of the largest Lisp string or buffer. See Eli
16881 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16883 * alloc.c (__malloc_size_t): Remove.
16884 All uses replaced by size_t. See Andreas Schwab's note
16885 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16887 * image.c: Improve checking for integer overflow.
16888 (check_image_size): Assume that f is nonnull, since
16889 it is always nonnull in practice. This is one less thing to
16890 worry about when checking for integer overflow later.
16891 (x_check_image_size): New function, which checks for integer
16892 overflow issues inside X.
16893 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16894 This removes the need for a memory_full check.
16895 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16896 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16897 (xbm_read_bitmap_data): Change locals back to 'int', since
16898 their values must fit in 'int'.
16899 (xpm_load_image, png_load, tiff_load):
16900 Invoke x_create_x_image_and_pixmap earlier,
16901 to avoid much needless work if the image is too large.
16902 (tiff_load): Treat overly large images as if
16903 x_create_x_image_and_pixmap failed, not as malloc failures.
16904 (gs_load): Use x_check_image_size.
16906 * gtkutil.c: Omit integer casts.
16907 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16908 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16910 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16912 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16913 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16914 would wrongly return t on a 64-bit host.
16916 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16917 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16918 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16919 and therefore cause GCC to emit a bogus diagnostic in some cases.
16921 * image.c: Integer signedness and overflow and related fixes.
16922 This is not an exhaustive set of fixes, but it's time to
16923 record what I've got.
16924 (lookup_pixel_color, check_image_size): Remove redundant decls.
16925 (check_image_size): Don't assume that arbitrary EMACS_INT values
16926 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16927 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16928 (tiff_load, imagemagick_load_image):
16929 Check for overflow in size calculations.
16930 (x_create_x_image_and_pixmap): Remove unnecessary test for
16931 xmalloc returning NULL; that can't happen.
16932 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16933 (xpm_color_bucket): Use better integer hashing function.
16934 (xpm_cache_color): Don't possibly over-allocate memory.
16935 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16936 (gif_memory_source):
16937 Use ptrdiff_t, not int or size_t, to record sizes.
16938 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16939 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16940 either works, as we prefer signed integers.
16941 (tiff_read_from_memory, tiff_write_from_memory):
16942 Return tsize_t, not size_t, since that's what the TIFF API wants.
16943 (tiff_read_from_memory): Don't fail simply because the read would
16944 go past EOF; instead, return a short read.
16945 (tiff_load): Omit no-longer-needed casts.
16946 (Fimagemagick_types): Don't assume size fits into 'int'.
16948 Improve hashing quality when configured --with-wide-int.
16949 * fns.c (hash_string): New function, taken from sxhash_string.
16950 Do not discard information about ASCII character case; this
16951 discarding is no longer needed.
16952 (sxhash-string): Use it. Change sig to match it. Caller changed.
16953 * lisp.h: Declare it.
16954 * lread.c (hash_string): Remove, since we now use fns.c's version.
16955 The fns.c version returns a wider integer if --with-wide-int is
16956 specified, so this should help the quality of the hashing a bit.
16958 * emacs.c: Integer overflow minor fix.
16959 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16960 Define only if GNU_LINUX.
16961 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16963 * dispnew.c: Integer signedness and overflow fixes.
16964 Remove unnecessary forward decls, that were a maintenance hassle.
16965 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16967 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16968 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16969 (prepare_desired_row, line_draw_cost):
16970 Use int, not unsigned, where either works.
16971 (save_current_matrix, restore_current_matrix):
16972 Use ptrdiff_t, not size_t, where either works.
16973 (init_display): Check for overflow more accurately, and without
16974 relying on undefined behavior.
16976 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16977 Remove, replacing with the new symbols in lisp.h. All uses changed.
16978 * fileio.c (make_temp_name):
16979 * filelock.c (lock_file_1, lock_file):
16980 * xdisp.c (message_dolog):
16981 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16982 Use pMd etc. instead.
16983 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16984 replacing the pWIDE etc. symbols removed from editfns.c.
16986 * keyboard.h (num_input_events): Now uintmax_t.
16987 This is (very slightly) less likely to mess up due to wraparound.
16990 * buffer.c: Integer signedness fixes.
16991 (alloc_buffer_text, enlarge_buffer_text):
16992 Use ptrdiff_t rather than size_t when either will do, as we prefer
16995 * alloc.c: Integer signedness and overflow fixes.
16996 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16997 (__malloc_size_t): Default to size_t, not to int.
16998 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16999 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17000 Prefer ptrdiff_t to size_t when either would do, as we prefer
17002 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17003 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17004 Now const. Initialize with values that are in range even if char
17006 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17007 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17008 These functions do the right thing with sizes > 2**32.
17009 (check_depth): Now ptrdiff_t, not int.
17010 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17011 Adjust to new way of storing sizes. Check for size overflow bugs
17013 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17014 slightly wrong anyway, as it missed one instance of
17015 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17016 (refill_memory_reserve): Omit needless cast to size_t.
17017 (mark_object_loop_halt): Mark as externally visible.
17019 * xselect.c: Integer signedness and overflow fixes.
17020 (Fx_register_dnd_atom, x_handle_dnd_message):
17021 Use ptrdiff_t, not size_t, since we prefer signed.
17022 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17023 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17024 x_dnd_atoms_size and x_dnd_atoms_length.
17026 * doprnt.c: Prefer signed to unsigned when either works.
17028 * doprnt.c (doprnt):
17030 * xdisp.c (vmessage):
17031 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17032 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17033 prefer signed arithmetic to avoid comparison confusion.
17034 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17035 but is a bit tricky.
17037 Assume freestanding C89 headers, string.h, stdlib.h.
17038 * data.c, doprnt.c, floatfns.c, print.c:
17039 Include float.h unconditionally.
17040 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17041 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17042 * regex.c: Likewise for stddef.h, string.h.
17043 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17044 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17045 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17046 (STDC_HEADERS): Remove obsolete defines.
17047 * sysdep.c: Include limits.h unconditionally.
17049 Assume support for memcmp, memcpy, memmove, memset.
17050 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17051 * regex.c (memcmp, memcpy):
17052 Remove; we assume C89 now.
17054 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17055 (__malloc_safe_bcopy): Remove; no longer needed.
17057 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17058 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17059 well either way, and we prefer signed to unsigned.
17061 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17063 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17064 closes the connection while we're reading (bug#9182).
17066 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17068 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17069 are specified (Bug#9168).
17071 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17073 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17074 Found by GCC static checking and --with-wide-int on a 32-bit host.
17076 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17078 * xdisp.c (compute_display_string_pos): Fix logic of caching
17079 previous display string position. Initialize cached_prev_pos to
17080 -1. Fixes slow-down at the beginning of a buffer.
17082 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17084 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17085 for attrs[LFACE_FONTSET_INDEX].
17087 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17089 * xml.c (parse_region): Remove unused local
17090 that was recently introduced.
17092 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17094 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17095 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17097 * xdisp.c (move_it_in_display_line_to): Record the best matching
17098 position for TO_CHARPOS while scanning the line, and restore it on
17099 exit if none of the characters scanned was an exact match.
17100 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17101 when exact match is impossible due to invisible text, and the
17102 lines are truncated.
17104 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17106 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17109 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17111 Fix a significant slow-down of cursor motion with C-n, C-p,
17112 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17113 auto-repeat under bidi redisplay in fontified buffers.
17114 * xdisp.c (compute_stop_pos_backwards): New function.
17115 (next_element_from_buffer): Call compute_stop_pos_backwards to
17116 find a suitable prev_stop when we find ourselves before
17118 (reseat): Don't look for prev_stop, as that could mean a very long
17120 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17121 <cached_disp_overlay_modiff>: Cache for last found display string
17123 (compute_display_string_pos): Return the cached position if asked
17124 about the same buffer in the same area of character positions, and
17125 the buffer wasn't changed since the time the display string
17126 position was cached.
17128 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17130 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17131 is an integer, which is important for empty lines. (Bug#9149)
17133 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17135 * frame.c (Fmodify_frame_parameters): In tty case, update the
17136 default face if necessary (Bug#4238).
17138 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17140 * editfns.c (Fstring_to_char): No need to explain what a character
17141 is in the docstring (Bug#6576).
17143 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17145 * xml.c (parse_region): Make sure we always return a tree.
17147 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17149 * xml.c (parse_region): If a document contains only comments,
17152 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17154 * xml.c (make_dom): Return comments, too.
17156 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17159 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17160 and the surrounding thread.
17161 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17162 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17163 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17165 * s/openbsd.h (BROKEN_SIGIO): Define.
17166 * unexelf.c (unexec) [__OpenBSD__]:
17167 Don't update the .mdebug section of the Alpha COFF symbol table.
17169 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17171 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17174 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17176 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17177 This fixes some race conditions on the permissions of any newly
17180 * alloc.c (valid_pointer_p): Use pipe, not open.
17181 This fixes some permissions issues when debugging.
17183 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17184 If fchown fails to set both uid and gid, try to set just gid,
17185 as that is sometimes allowed. Adjust the file's mode to eliminate
17186 setuid or setgid bits that are inappropriate if fchown fails.
17188 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17190 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17191 to compare Lisp_Objects.
17192 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17193 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17194 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17196 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17198 * lread.c (read_integer): Unread even EOF character.
17199 (read1): Likewise. Properly record start position of symbol.
17201 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17202 symbol character follows.
17204 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17206 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17207 This works around a problem with the previous change to Fcopy_file.
17208 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17209 and without this change, GCC might complain about discarding
17210 fchown's return value.
17212 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17214 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17216 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17218 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17220 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17222 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17223 it's used from the C level.
17225 * process.c: Use the same condition for POLL_FOR_INPUT in both
17226 keyboard.c and process.c (bug#1858).
17228 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17230 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17231 (Fgnutls_boot): Use it.
17233 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17235 * doc.c (Fsubstitute_command_keys): Revert last change.
17237 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17239 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17240 quotes the next character, and doesn't affect other longer
17241 sequences (bug#8935).
17243 * lread.c (syms_of_lread): Clarify that is isn't only
17244 `eval-buffer' and `eval-defun' that's affected by
17245 `lexical-binding' (bug#8460).
17247 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17249 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17250 bidi redisplay when a line includes both an image and is truncated.
17252 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17254 Fix minor problems found by static checking.
17255 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17256 (elsz): Now a signed constant, not a size_t var. We prefer signed
17257 types to unsigned, to avoid integer comparison confusion. Without
17258 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17259 "cannot optimize loop, the loop counter may overflow", a symptom
17261 * indent.c (Fvertical_motion): Mark locals as initialized.
17262 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17264 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17266 * search.c (Fre_search_backward): Mention `case-fold-search' in
17267 all the re_search_* functions (bug#8138).
17269 * keyboard.c (Fopen_dribble_file): Document when the file is
17272 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17274 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17277 Support bidi reordering of display and overlay strings.

17279 (compute_display_string_end): Accept additional argument STRING.
17280 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17281 (reseat_to_string): Initialize bidi_it->string.s and
17282 bidi_it->string.schars.
17283 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17284 NULL (avoids a crash in bidi_paragraph_init).
17285 Initialize itb.string.lstring.
17286 (init_iterator): Call bidi_init_it only of a valid
17287 buffer position was specified. Initialize paragraph_embedding to
17289 (reseat_to_string): Initialize the bidi iterator.
17290 (display_string): If we need to ignore text properties of
17291 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17292 original value of -1 will not work with bidi.)
17293 (compute_display_string_pos): First arg is now struct
17294 `text_pos *'; all callers changed. Support display properties on
17296 (compute_display_string_end): Support display properties on Lisp
17298 (init_iterator, reseat_1, reseat_to_string): Initialize the
17299 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17300 when iterating on a string not from display properties).
17301 (compute_display_string_pos, compute_display_string_end):
17302 Fix calculation of the object to scan. Fixes an error when using
17304 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17305 base_level_stop; instead, set base_level_stop to BEGV.
17306 Fixes crashes in vertical-motion.
17307 (next_element_from_buffer): Improve commentary for when
17308 the iterator is before prev_stop.
17309 (init_iterator): Initialize bidi_p from the default value of
17310 bidi-display-reordering, not from buffer-local value. Use the
17311 buffer-local value only if initializing for buffer iteration.
17312 (handle_invisible_prop): Support invisible properties on strings
17313 that are being bidi-reordered.
17314 (set_iterator_to_next): Support bidi reordering of C strings and
17316 (next_element_from_string): Support bidi reordering of Lisp
17318 (handle_stop_backwards): Support Lisp strings as well.
17319 (display_string): Support display of R2L glyph rows.
17320 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17321 (init_iterator): Don't initialize it->bidi_p for strings
17323 (reseat_to_string): Initialize it->bidi_p for strings here.
17324 (next_element_from_string, next_element_from_c_string)
17325 (next_element_from_buffer): Add xassert's for correspondence
17326 between IT's object being iterated and it->bidi_it.string
17328 (face_before_or_after_it_pos): Support bidi iteration.
17329 (next_element_from_c_string): Handle the case of the first string
17330 character that is not the first one in the visual order.
17331 (get_visually_first_element): New function, refactored from common
17332 parts of next_element_from_buffer, next_element_from_string, and
17333 next_element_from_c_string.
17334 (tool_bar_lines_needed, redisplay_tool_bar)
17335 (display_menu_bar): Force left-to-right direction. Add a FIXME
17336 comment for making that be controlled by a user option.
17337 (push_it, pop_it): Save and restore the state of the
17338 bidi iterator. Save and restore the bidi_p flag.
17339 (pop_it): Iterate out of display property for string iteration as
17341 (iterate_out_of_display_property): Support iteration over strings.
17342 (handle_single_display_spec): Set up it->bidi_it for iteration
17343 over a display string, and call bidi_init_it.
17344 (handle_single_display_spec, next_overlay_string)
17345 (get_overlay_strings_1, push_display_prop): Set up the bidi
17346 iterator for displaying display or overlay strings.
17347 (forward_to_next_line_start): Don't use the shortcut if
17349 (back_to_previous_visible_line_start): If handle_display_prop
17350 pushed the iterator stack, restore the internal state of the bidi
17351 iterator by calling bidi_pop_it same number of times.
17352 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17353 and we are bidi-iterating, don't decrement the iterator position;
17354 instead, set the first_elt flag in the bidi iterator, to produce
17356 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17357 (push_display_prop): xassert that we are iterating a buffer.
17358 (push_it, pop_it): Save and restore paragraph_embedding member.
17359 (handle_single_display_spec, next_overlay_string)
17360 (get_overlay_strings_1, reseat_1, reseat_to_string)
17361 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17362 correctly. Don't assume unibyte strings are not bidi-reordered.
17363 (compute_display_string_pos)
17364 (compute_display_string_end): Fix handling the case of C string.
17365 (push_it, pop_it): Save and restore from_disp_prop_p.

17825 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
17827 Random fixes. E.g., (random) never returned negative values.
17828 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17829 subseconds part to the entropy, as that's a bit more random.
17830 Prefer signed to unsigned, since the signedness doesn't matter and
17831 in general we prefer signed. When given a limit, use a
17832 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17833 latter isn't right if USE_2_TAGS_FOR_INTS.
17834 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17835 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17837 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17839 * textprop.c (text_property_stickiness):
17840 Obey Vtext_property_default_nonsticky.

17847 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17848 This is more efficient than Ffile_directory_p and avoids a minor race.
17850 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17852 * buffer.c (Foverlay_put): Say what the return value is
17855 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17856 is a directory before asking whether to use the file name
17858 (barf_or_query_if_file_exists): Make the "File is a directory"
17859 error be more correct.
17861 * fns.c (Frequire): Remove the mention of the .gz files, since
17862 that's installation-specific, but keep the mention of
17863 `get-load-suffixes'.
17865 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17867 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17872 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
17873 (syms_of_gnutls): Remove duplicate DEFSYM for
17874 Qgnutls_bootprop_verify_hostname_error, an error for
17875 Qgnutls_bootprop_verify_error (which is no longer used).
17877 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17878 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17879 Also (re)move comments that are misplaced or no longer relevant.
17881 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17883 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17911 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17912 (Frequire): Mention get-load-suffixes.

17942 (syms_of_keymap): Defsubr make-composed-keymap.
17943 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17980 * eval.c (struct backtrace): Simplify and port the data structure.
17981 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17982 signed bit field, as this assumption is not portable and it makes
17983 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17984 "char debug_on_exit : 1" as this is not portable either; instead,
17985 use the portable "unsigned int debug_on_exit : 1". Remove unused
17986 member evalargs. Remove obsolete comments about cc bombing out.
17988 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
17990 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

18056 (emacs_fixed_new): Set priv->f to argument.
18057 (emacs_fixed_get_preferred_width)
18058 (emacs_fixed_get_preferred_height): Use min_width/height from
18059 frames size_hint to set minimum and natural (Bug#8919).
18060 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18061 and use min_width/height from frames size_hint to set
18062 min_width/height (Bug#8919).

18154 * print.c (printchar, strout): Check for string overflow.
18155 (PRINTPREPARE, printchar, strout):
18156 Don't set size unless allocation succeeds.
18158 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18159 for sizes. Check for string overflow more accurately.

18173 (read_integer): Radix is now EMACS_INT, not int,
18174 to improve quality of diagnostics for out-of-range radices.
18175 Calculate buffer size correctly for out-of-range radices.
18176 (read1): Check for integer overflow in radices, and in
18177 read-circle numbers.
18178 (read_escape): Avoid int overflow.
18179 (Fload, openp, read_buffer_size, read1)
18180 (substitute_object_recurse, read_vector, read_list, map_obarray):
18181 Use ptrdiff_t, not int, for sizes.

18201 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18203 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18204 The following patches are for when GLYPH_DEBUG && !XASSERT.
18205 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18206 * dispnew.c (flush_stdout):
18207 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18208 Mark as externally visible.
18209 * dispnew.c (check_window_matrix_pointers): Now static.
18210 * dispnew.c (window_to_frame_vpos):
18211 * xfns.c (unwind_create_frame):
18212 * xterm.c (x_check_font): Remove unused local.
18213 * scroll.c (CHECK_BOUNDS):
18214 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18215 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.

18218 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18220 (debug_method_add): Use va_list and vsprintf rather than relying
18221 on undefined behavior with wrong number of arguments.
18222 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18223 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18224 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18225 since we're not interested in debugging glyphs with old libraries.
18226 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18227 GCC 4.6.0's static checking.
18229 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18231 Integer overflow and signedness fixes (Bug#8873).

18245 * xfaces.c (load_pixmap):
18246 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18247 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18248 (.bitmaps_last, struct x_output.icon_bitmap):
18249 Use ptrdiff_t, not int, for bitmap indexes.
18250 (x_allocate_bitmap_record): Check for size overflow.
18251 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18253 Use ptrdiff_t, not int, for overlay counts.
18254 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18255 * editfns.c (overlays_around, get_pos_property):
18256 * textprop.c (get_char_property_and_overlay):
18257 * xdisp.c (next_overlay_change, note_mouse_highlight):
18258 * xfaces.c (face_at_buffer_position):
18259 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18260 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18261 (Fnext_overlay_change, Fprevious_overlay_change)
18262 (mouse_face_overlay_overlaps, Foverlays_in):
18263 Use ptrdiff_t, not int, for sizes.
18264 (overlays_at, overlays_in): Check for size-calculation overflow.
18266 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18268 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18269 (x_session_initialize): Do not assume string length fits in int.
18271 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18272 This is unlikely, but can occur if DPI is outlandish.
18274 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18275 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18277 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18278 * xrdb.c (magic_file_p, search_magic_path):
18279 Omit last arg SUFFIX; it was always 0. All callers changed.
18280 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18282 * xfont.c (xfont_match): Avoid need for strlen.
18284 * xfns.c: Don't assume strlen fits in int.
18285 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18287 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18288 not unsigned long, as we prefer signed integers. All callers changed.
18289 Detect integer overflow in repeat count.
18290 (message_dolog): Don't assume print length fits in 39 bytes.
18291 (display_mode_element): Don't assume strlen fits in int.
18293 * termcap.c: Don't assume sizes fit in int and never overflow.
18294 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18295 (gobble_line): Check for size-calculation overflow.
18297 * minibuf.c (Fread_buffer):
18298 * lread.c (intern, intern_c_string):
18299 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18300 Don't assume string length fits in int.
18302 * keyboard.c (parse_tool_bar_item):
18303 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18305 * font.c: Don't assume string length fits in int.
18306 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18307 Use ptrdiff_t, not int.
18308 (font_intern_prop): Don't assume string length fits in int.
18309 Don't assume integer property fits in fixnum.
18310 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18312 * filelock.c: Fix some buffer overrun and integer overflow issues.
18313 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18314 Reformulate so as not to need the command string.
18315 Invoke gzip -cd rather than gunzip, as it's more portable.
18316 (lock_info_type, lock_file_1, lock_file):
18317 Don't assume pid_t and time_t fit in unsigned long.
18318 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18319 (current_lock_owner): Prefer signed type for sizes.
18320 Use memcpy, not strncpy, where memcpy is what is really wanted.
18321 Don't assume (via atoi) that time_t and pid_t fit in int.
18322 Check for time_t and/or pid_t out of range, e.g., via a network share.
18323 Don't alloca where an auto var works fine.
18325 * fileio.c: Fix some integer overflow issues.
18326 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18327 Don't assume string length fits in int.
18328 (directory_file_name): Don't assume string length fits in long.
18329 (make_temp_name): Don't assume pid fits in int, or that its print
18330 length is less than 20.
18332 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18334 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18336 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18338 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18339 We prefer signed integers, even for size calculations.
18341 * emacs.c: Don't assume string length fits in 'int'.
18342 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18343 (main): Don't invoke strlen when not needed.
18345 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18346 (XD_DEBUG_MESSAGE): Don't waste a byte.
18348 * callproc.c (getenv_internal_1, getenv_internal)
18349 (Fgetenv_internal):
18350 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18352 * lread.c (invalid_syntax): Omit length argument.
18353 All uses changed. This doesn't fix a bug, but it simplifies the
18354 code away from its former Hollerith-constant appearance, and it's
18355 one less 'int' to worry about when looking at integer-overflow issues.
18356 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18358 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18359 This didn't break anything, but it didn't help either.
18360 It's confusing to put a bogus integer in a place where the actual
18361 value does not matter.
18362 (LIST_END_P): Remove unused macro and its bogus comment.
18363 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18365 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18366 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18368 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18369 We prefer signed types, and the value cannot exceed the EMACS_INT
18370 range anyway (because otherwise the length would not be representable).
18371 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18372 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18373 This avoids a GCC warning when WIDE_EMACS_INT.
18375 * indent.c (sane_tab_width): New function.
18376 (current_column, scan_for_column, Findent_to, position_indentation)
18377 (compute_motion): Use it. This is just for clarity.
18378 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18380 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18382 * lisp.h (lint_assume): New macro.
18383 * composite.c (composition_gstring_put_cache):
18384 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18386 * editfns.c, insdel.c:
18387 Omit unnecessary forward decls, to simplify future changes.
18389 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18391 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18393 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18394 Use much-faster test for byte-length change.
18395 Don't assume string byte-length fits in 'int'.
18396 Check that character arg fits in 'int'.
18397 (mapcar1): Declare byte as byte, for clarity.
18399 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18401 * fns.c (concat): Catch string overflow earlier.
18402 Do not rely on integer wraparound.
18404 * dispextern.h (struct it.overlay_strings_charpos)
18405 (struct it.selective): Now EMACS_INT, not int.
18406 * xdisp.c (forward_to_next_line_start)
18407 (back_to_previous_visible_line_start)
18408 (reseat_at_next_visible_line_start, next_element_from_buffer):
18409 Don't arbitrarily truncate the value of 'selective' to int.
18411 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18413 * composite.c: Don't truncate sizes to 'int'.
18414 (composition_gstring_p, composition_reseat_it)
18415 (composition_adjust_point): Use EMACS_INT, not int.
18416 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18417 not EMACS_UINT, for indexes.
18419 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18421 * buffer.c: Include <verify.h>.
18422 (struct sortvec.priority, struct sortstr.priority):
18423 Now EMACS_INT, not int.
18424 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18425 (struct sortstr.size, record_overlay_string)
18426 (struct sortstrlist.size, struct sortlist.used):
18427 Don't truncate size to int.
18428 (record_overlay_string): Check for size-calculation overflow.
18429 (init_buffer_once): Check at compile-time, not run-time.
18431 2011-06-22 Jim Meyering <meyering@redhat.com>
18433 Don't leak an XBM-image-sized buffer
18434 * image.c (xbm_load): Free the image buffer after using it.
18436 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18439 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18440 that Sun C diagnosed.
18441 * fns.c (secure_hash): Fix pointer signedness issue.
18442 * intervals.c (static_offset_intervals): New function.
18443 (offset_intervals): Use it.
18445 2011-06-21 Leo Liu <sdl.web@gmail.com>
18448 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18451 * fns.c (secure_hash): Rename from crypto_hash_function and change
18452 the first arg to accept symbols.
18453 (Fsecure_hash): New primitive.
18454 (syms_of_fns): New symbols.
18456 2011-06-20 Deniz Dogan <deniz@dogan.se>
18458 * process.c (Fset_process_buffer): Clarify return value in
18461 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18463 * dispnew.c (add_window_display_history): Use BVAR.
18465 * xdisp.c (debug_method_add): Use BVAR.
18466 (check_window_end, dump_glyph_matrix, dump_glyph)
18467 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18469 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18472 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18473 check till after the cache is created in init_frame_faces.
18475 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18477 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18479 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18481 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18482 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18483 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18485 Improve buffer-overflow checking (Bug#8873).
18486 * fileio.c (Finsert_file_contents):
18487 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18488 Remove the old (too-loose) buffer overflow checks.
18489 They weren't needed, since make_gap checks for buffer overflow.
18490 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18491 The old code merely checked for Emacs fixnum overflow, and relied
18492 on undefined (wraparound) behavior. The new code avoids undefined
18493 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18495 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18496 Tune. Don't use wider integers than needed. Don't use alloca.
18497 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18499 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18501 * insdel.c, lisp.h (buffer_overflow): New function.
18502 (insert_from_buffer_1, replace_range, replace_range_2):
18503 * insdel.c (make_gap_larger):
18504 * editfns.c (Finsert_char):
18505 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18507 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18509 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18511 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18513 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18514 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18516 * fileio.c: Don't assume EMACS_INT fits in off_t.
18517 (emacs_lseek): New static function.
18518 (Finsert_file_contents, Fwrite_region): Use it.
18519 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18521 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18523 * fns.c: Don't overflow int when computing a list length.
18524 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18525 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18526 truncation on 64-bit hosts. Check for QUIT every
18527 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18528 faster and is responsive enough.
18529 (Flength): Report an error instead of overflowing an integer.
18530 (Fsafe_length): Return a float if the value is not representable
18531 as a fixnum. This shouldn't happen except in contrived situations.
18532 (Fnthcdr, Fsort): Don't assume list length fits in int.
18533 (Fcopy_sequence): Don't assume vector length fits in int.
18535 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18536 (header_size, word_size): New constants.
18537 (allocate_vectorlike): Don't check size overflow here.
18538 (allocate_vector): Check it here instead, since this is the only
18539 caller of allocate_vectorlike that could cause overflow.
18540 Check that the new vector's length is representable as a fixnum.
18542 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18543 The previous code was bogus. For example, next_almost_prime (32)
18544 returned 39, which is undesirable as it is a multiple of 3; and
18545 next_almost_prime (24) returned 25, which is a multiple of 5 so
18546 why was the code bothering to check for multiples of 7?
18548 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18550 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18552 Variadic C functions now count arguments with ptrdiff_t.
18553 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18554 Back then I didn't know that the Emacs coding style prefers signed int.
18555 Also, in the meantime I found a few more instances where arguments
18556 were being counted with int, which may truncate counts on 64-bit
18557 machines, or EMACS_INT, which may be unnecessarily wide.
18558 * lisp.h (struct Lisp_Subr.function.aMANY)
18559 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18560 Arg counts are now ptrdiff_t, not size_t.
18561 All variadic functions and their callers changed accordingly.
18562 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18563 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18564 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18565 * callint.c (Fcall_interactively): Check arg count for overflow,
18566 to avoid potential buffer overrun. Use signed char, not 'int',
18567 for 'varies' array, so that we needn't bother to check its size
18568 calculation for overflow.
18569 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18570 * eval.c (apply_lambda):
18571 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18572 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18573 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18575 * callint.c (Fcall_interactively): Don't use index var as event count.
18577 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18578 * mem-limits.h (SIZE): Remove; no longer used.
18580 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18582 Remove unnecessary casts.
18583 * xterm.c (x_term_init):
18584 * xfns.c (x_set_border_pixel):
18585 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18586 These aren't needed now that we assume ANSI C.
18588 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18589 It's more likely to cause problems (due to unsigned overflow)
18592 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18594 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18596 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18598 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18600 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18602 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18604 GLYPH_CODE_FACE returns EMACS_INT, not int.
18605 * dispextern.h (merge_faces):
18606 * xfaces.c (merge_faces):
18607 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18608 Don't assume EMACS_INT fits in int.
18610 * character.h (CHAR_VALID_P): Remove unused parameter.
18611 * fontset.c, lisp.h, xdisp.c: All uses changed.
18613 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18615 * fns.c (concat): Minor tuning based on overflow analysis.
18616 This doesn't fix any bugs. Use int to hold character, instead
18617 of constantly refetching from Emacs object. Use XFASTINT, not
18618 XINT, for value known to be a character. Don't bother comparing
18619 a single byte to 0400, as it's always less.
18621 * floatfns.c (Fexpt):
18622 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18624 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18627 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18629 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18630 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18631 incorrectly succeed when S was a string, because 4294967386 was
18632 truncated before it was used.
18634 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18635 Otherwise, an out-of-range integer could cause undefined behavior
18638 * composite.c: Use int, not EMACS_INT, for characters.
18639 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18640 EMACS_INT, for values that are known to be in character range.
18641 This doesn't fix any bugs but is the usual style inside Emacs and
18642 may generate better code on 32-bit machines.
18644 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18645 This is for reasons similar to the recent CHAR_STRING fix.
18646 * charset.c (Fencode_char): Check that character arg is actually
18647 a character. Pass an int to ENCODE_CHAR.
18648 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18649 wider than 'int', as a compile-time check to prevent future regressions
18652 * character.c (char_string): Remove unnecessary casts.
18654 Make sure a 64-bit char is never passed to CHAR_STRING.
18655 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18656 by silently ignoring the top 32 bits, allowing some values
18657 that were far too large to be valid characters.
18658 * character.h: Include <verify.h>.
18659 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18660 arguments are no wider than unsigned, as a compile-time check
18661 to prevent future regressions in this area.
18663 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18664 (Fsubst_char_in_region):
18666 * xdisp.c (decode_mode_spec_coding):
18667 Adjust to CHAR_STRING's new requirement.
18668 * editfns.c (Finsert_char, Fsubst_char_in_region):
18669 * fns.c (concat): Check that character args are actually
18670 characters. Without this test, these functions did the wrong
18671 thing with wildly out-of-range values on 64-bit hosts.
18673 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18674 These casts should not be needed on 32-bit hosts, either.
18675 * keyboard.c (read_char):
18676 * lread.c (Fload): Remove casts to unsigned.
18678 * lisp.h (UNSIGNED_CMP): New macro.
18679 This fixes comparison bugs on 64-bit hosts.
18680 (ASCII_CHAR_P): Use it.
18681 * casefiddle.c (casify_object):
18682 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18683 (SINGLE_BYTE_CHAR_P, CHAR_STRING):

18736 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18737 when a (possibly-narrower) signed value would do just as well.
18738 We prefer using signed arithmetic, to avoid comparison confusion.
18740 * alloc.c: Catch some string size overflows that we were missing.
18741 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18742 for convenience in STRING_BYTES_MAX.
18743 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18744 The definition here is exact; the one in lisp.h was approximate.
18745 (allocate_string_data): Check for string overflow. This catches
18746 some instances we weren't catching before. Also, it catches
18747 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18748 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18749 and ptrdiff_t and EMACS_INT are both 64 bits.
18751 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18752 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

19330 instead of using explicit *_CHAR codes.
19331 (bidi_resolve_explicit, bidi_resolve_weak):

19340 (bidi_level_of_next_char): Don't try to lookup the cache for the
19341 next/previous character if nothing is cached there yet, or if we
19342 were just reseat()'ed to a new position.
19344 * xdisp.c (set_cursor_from_row): Set start and stop points
19345 according to the row's direction when priming the loop that looks
19346 for the glyph on which to display cursor.

19348 (display_prop_intangible_p): Reimplement to call
19349 handle_display_spec instead of single_display_spec_intangible_p.
19350 Accept 3 additional arguments needed by handle_display_spec.
19351 This fixes incorrect cursor motion across display property with complex

19360 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19361 value of a `display' property is a "replacing spec".
19362 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19363 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19364 the display property, but just return a value indicating whether
19365 the display property will replace the characters it covers.
19366 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19367 frame_window_p members of struct bidi_it.

19393 * gnutls.c: Use Emacs's memory allocators.
19394 Without this change, the gnutls library would invoke malloc etc.
19395 directly, which causes problems on non-SYNC_INPUT hosts, and which
19396 runs afoul of improving memory_full behavior. (Bug#8761)
19397 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19398 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19399 xfree instead of the default malloc, realloc, free.
19400 (Fgnutls_boot): No need to check for memory allocation failure,
19401 since xmalloc does that for us.

19424 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19425 * alloc.c (allocate_vectorlike):
19426 Check for overflow in vector size calculations.
19427 * ccl.c (ccl_driver):
19428 Check for overflow when converting EMACS_INT to int.

19430 need to be updated by these changes.
19431 * fns.c (make_hash_table, maybe_resize_hash_table):
19432 Check for integer overflow with large hash tables.
19433 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19434 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19435 (SXHASH_REDUCE): New macro.
19436 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19437 Use it instead of discarding useful hash info with large hash values.
19438 (sxhash_float): New function.
19439 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19440 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19441 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19442 Rewrite to use FIXNUM_BITS, as this simplifies things.
19443 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19444 Adjust signatures to match updated version of code.
19445 (consing_since_gc): Now EMACS_INT, since a single hash table can
19446 use more than INT_MAX bytes.

19495 Make it possible to run ./temacs.
19497 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19498 syms_of_callproc does the same thing. Remove test for

19556 2011-05-28 Jim Meyering <meyering@redhat.com>
19558 Avoid a sign-extension bug in crypto_hash_function.
19559 * fns.c (to_uchar): Define.
19560 (crypto_hash_function): Use it to convert some newly-signed
19561 variables to unsigned, to avoid sign-extension bugs. For example,
19562 without this change, (md5 "truc") would evaluate to
19563 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19564 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19565 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19567 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19569 Integer overflow fixes.
19571 * dbusbind.c: Serial number integer overflow fixes.
19572 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19573 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19574 to hold a serial number that is too large for a fixnum.
19575 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19576 Check for serial numbers out of range. Decode any serial number
19577 that was so large that it became a float. (Bug#8722)
19579 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19580 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19581 Use XFASTINT rather than XUINT when numbers are nonnegative.
19582 (xd_append_arg, Fdbus_method_return_internal):
19583 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19584 arguments, check that Lisp number is nonnegative, rather than
19585 silently wrapping negative numbers around. (Bug#8722)
19586 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19589 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19591 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19593 ccl: Add integer overflow checks.
19594 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19595 (IN_INT_RANGE): New macros.
19596 (ccl_driver): Use them to check for integer overflow when
19597 decoding a CCL program. Many of the new checks are whether XINT (x)
19598 fits in int; it doesn't always, on 64-bit hosts. The new version
19599 doesn't catch all possible integer overflows, but it's an
19600 improvement. (Bug#8719)
19602 * alloc.c (make_event_array): Use XINT, not XUINT.
19603 There's no need for unsigned here.
19605 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19606 This follows up to the 2011-05-06 change that substituted uintptr_t
19607 for EMACS_INT. This case wasn't caught back then.
19609 Rework Fformat to avoid integer overflow issues.
19610 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19611 now (part of C89). Include <verify.h>.
19612 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19613 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19614 (Fformat): Avoid the prepass trying to compute sizes; it was only
19615 approximate and thus did not catch overflow reliably. Instead, walk
19616 through the format just once, formatting and computing sizes as we go,
19617 checking for integer overflow at every step, and allocating a larger
19618 buffer as needed. Keep track separately whether the format is
19619 multibyte. Keep only the most-recently calculated precision, rather
19620 than them all. Record whether each argument has been converted to
19621 string. Use EMACS_INT, not int, for byte and char and arg counts.
19622 Support field widths and precisions larger than INT_MAX. Avoid
19623 sprintf's undefined behavior with conversion specifications such as %#d
19624 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19625 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19626 formatting out-of-range floating point numbers with int
19627 formats. (Bug#8668)
19629 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19631 * data.c: Avoid integer truncation in expressions involving floats.
19632 * data.c: Include <intprops.h>.
19633 (arith_driver): When there's an integer overflow in an expression
19634 involving floating point, convert the integers to floating point
19635 so that the resulting value does not suffer from catastrophic
19636 integer truncation. For example, on a 64-bit host (* 4
19637 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19638 Do not rely on undefined behavior after integer overflow.
19640 merge count_size_as_multibyte, parse_str_to_multibyte
19641 * character.c, character.h (count_size_as_multibyte):
19642 Rename from parse_str_to_multibyte; all uses changed.
19643 Check for integer overflow.
19644 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19645 since it's now a duplicate of the other. This is more of
19646 a character than a buffer op, so better that it's in character.c.
19647 * fns.c, print.c: Adjust to above changes.
19649 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19651 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19653 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19655 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19656 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19657 (x_clipboard_manager_save): Now static.
19658 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19660 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19661 (crypto_hash_function): Now static.
19662 Fix pointer signedness problems. Avoid unnecessary initializations.
19664 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19666 * termhooks.h (Vselection_alist): Make it terminal-local.
19668 * terminal.c (create_terminal): Initialize it.
19670 * xselect.c: Support for clipboard managers.
19671 (Vselection_alist): Move to termhooks.h as terminal-local var.
19672 (LOCAL_SELECTION): New macro.
19673 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19674 (symbol_to_x_atom): Remove gratuitous arg.
19675 (x_handle_selection_request, lisp_data_to_selection_data)
19676 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19677 (x_own_selection, x_get_local_selection, x_convert_selection):
19678 New arg, specifying work frame. Use terminal-local Vselection_alist.
19679 (some_frame_on_display): Delete unused function.
19680 (Fx_own_selection_internal, Fx_get_selection_internal)
19681 (Fx_disown_selection_internal, Fx_selection_owner_p)
19682 (Fx_selection_exists_p): New optional frame arg.
19683 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19684 (x_handle_selection_clear): Don't treat other terminals with the
19685 same keyboard specially. Use the terminal-local Vselection_alist.
19686 (x_clear_frame_selections): Use Frun_hook_with_args.
19688 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19690 * xterm.h: Add support for those atoms.
19692 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19694 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19695 (converted_selections, conversion_fail_tag): New global variables.
19696 (x_selection_request_lisp_error): Free the above.
19697 (x_get_local_selection): Remove unnecessary code.
19698 (x_reply_selection_request): Args changed; handle arbitrary array
19699 of converted selections stored in converted_selections.
19700 Separate the XChangeProperty and SelectionNotify steps.
19701 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19702 (x_convert_selection): New function.
19703 (x_handle_selection_event): Simplify.
19704 (x_get_foreign_selection): Don't ignore incoming requests while
19705 waiting for an answer; this will fail when we implement
19706 SAVE_TARGETS, and seems unnecessary anyway.
19707 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19708 (Vx_sent_selection_functions): Doc fix.
19710 2011-05-26 Leo Liu <sdl.web@gmail.com>
19712 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19714 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19716 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19718 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19719 for fringe update if it has periodic bitmap.
19720 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19721 and fringe_bitmap_periodic_p.
19723 * fringe.c (get_fringe_bitmap_data): New function.
19724 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19725 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19726 row. Mark glyph row for fringe update if periodicity changed.
19728 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19729 for fringe update unless it has periodic bitmap.
19731 2011-05-25 Kenichi Handa <handa@m17n.org>
19733 * xdisp.c (get_next_display_element): Set correct it->face_id for
19734 a static composition.
19736 2011-05-24 Leo Liu <sdl.web@gmail.com>
19739 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19741 * fns.c (crypto_hash_function, Fsha1): New function.
19742 (Fmd5): Use crypto_hash_function.
19743 (syms_of_fns): Add Ssha1.
19745 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19747 * gnutls.c: Remove unused macros.
19748 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19749 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19750 Remove macros that are defined and never used.
19751 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19753 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19755 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19756 (Fx_get_selection_internal): Minor cleanup.
19757 (Fx_own_selection_internal): Rename arguments for consistency with
19760 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19762 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19764 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19766 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19768 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19770 * dispnew.c (scrolling_window): Don't exclude the case that the
19771 last enabled row in the desired matrix touches the bottom boundary.
19773 2011-05-21 Glenn Morris <rgm@gnu.org>
19775 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19776 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19777 and add some more files.
19779 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19781 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19782 report_file_error introduced by the change from 2011-05-07.
19784 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19786 * systime.h (Time): Define only if emacs is defined.
19787 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19788 where the include path doesn't have X11/X.h by default. See
19789 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19791 2011-05-20 Kenichi Handa <handa@m17n.org>
19793 * composite.c (find_automatic_composition): Fix previous change.
19795 2011-05-20 Glenn Morris <rgm@gnu.org>
19797 * lisp.mk: New file, split from Makefile.in.
19798 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19799 (shortlisp): Remove.
19800 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19802 2011-05-19 Glenn Morris <rgm@gnu.org>
19804 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19805 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19806 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19807 (lisp): Set the order to that of loadup.el.
19808 (shortlisp): Make it a copy of $lisp.
19809 (SOME_MACHINE_LISP): Remove.
19810 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19811 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19813 2011-05-18 Kenichi Handa <handa@m17n.org>
19815 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19816 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19817 (find_automatic_composition): Mostly rewrite for efficiency.
19819 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19821 * makefile.w32-in: Update dependencies.
19823 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19825 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19826 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19828 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19830 Fix some integer overflow issues, such as string length overflow.
19832 * insdel.c (count_size_as_multibyte): Check for string overflow.
19834 * character.c (lisp_string_width): Check for string overflow.
19835 Use EMACS_INT, not int, for string indexes and lengths; in
19836 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19837 the resulting string length overflows an EMACS_INT; instead,
19838 report a string overflow if no precision given. When checking for
19839 precision exhaustion, use a check that cannot possibly have
19840 integer overflow. (Bug#8675)
19841 * character.h (lisp_string_width): Adjust to new signature.
19843 * alloc.c (string_overflow): New function.
19844 (Fmake_string): Use it. This doesn't change behavior, but saves
19845 a few bytes and will simplify future changes.
19846 * character.c (string_escape_byte8): Likewise.
19847 * lisp.h (string_overflow): New decl.
19849 Fixups, following up to the user-interface timestamp change.
19850 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19851 for UI timestamps, instead of unsigned long.
19852 * msdos.c (mouse_get_pos): Likewise.
19853 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19854 * w32gui.h (Time): Define by including "systime.h" rather than by
19855 declaring it ourselves. (Bug#8664)
19857 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19858 * image.c (clear_image_cache): Likewise.
19860 * term.c (term_mouse_position): Don't assume time_t wraparound.
19862 Be more systematic about user-interface timestamps.
19863 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19864 and sometimes 'EMACS_UINT', to represent these timestamps.
19865 This change causes it to use 'Time' uniformly, as that's what X uses.
19866 This makes the code easier to follow, and makes it easier to catch
19867 integer overflow bugs such as Bug#8664.
19868 * frame.c (Fmouse_position, Fmouse_pixel_position):
19869 Use Time, not unsigned long, for user-interface timestamps.
19870 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19871 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19872 * keyboard.h (last_event_timestamp): Likewise.
19873 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19874 * menu.h (xmenu_show): Likewise.
19875 * term.c (term_mouse_position): Likewise.
19876 * termhooks.h (struct input_event.timestamp): Likewise.
19877 (struct terminal.mouse_position_hook): Likewise.
19878 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19879 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19880 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19881 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19882 what it was before.
19883 * menu.h, termhooks.h: Include "systime.h", for Time.
19885 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19886 Don't assume that the difference between two unsigned long values
19887 can fit into an integer. At this point, we know button_down_time
19888 <= event->timestamp, so the difference must be nonnegative, so
19889 there's no need to cast the result if double-click-time is
19890 nonnegative, as it should be; check that it's nonnegative, just in
19891 case. This bug is triggered when events are more than 2**31 ms
19892 apart (about 25 days). (Bug#8664)
19894 * xselect.c (last_event_timestamp): Remove duplicate decl.
19895 (x_own_selection): Remove needless cast to unsigned long.
19897 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19898 that always fit in int. Use a sentinel instead of a counter, to
19899 avoid a temp and to allay GCC's concerns about possible int overflow.
19900 * frame.h (struct frame): Use int for menu_bar_items_used
19901 instead of EMACS_INT, since it always fits in int.
19903 * menu.c (grow_menu_items): Check for int overflow.
19905 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19907 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19908 Before, the code was not consistent. These values cannot exceed
19909 2**31 - 1 so there's no need to make them unsigned.
19910 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19911 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19912 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19914 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19916 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19917 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19918 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19919 presumably because the widths might not match.
19921 * window.c (size_window): Avoid needless test at loop start.
19923 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19925 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19927 2011-05-12 Drew Adams <drew.adams@oracle.com>
19929 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19931 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19933 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19934 `width' to `bar_area_x' and `bar_area_width', respectively.
19935 (x_scroll_run): Take account of fringe background extension.
19937 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19938 Rename local vars `left' and `width' to `bar_area_x' and
19939 `bar_area_width', respectively.
19940 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19941 background extension.
19943 2011-05-10 Jim Meyering <meyering@redhat.com>
19945 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19947 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19949 * image.c (Finit_image_library): Return t for built-in image types,
19950 like pbm and xbm. (Bug#8640)
19952 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19954 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19956 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19958 * w32console.c (Fset_screen_color): Doc fix.
19959 (Fget_screen_color): New function.
19960 (syms_of_ntterm): Defsubr it.
19962 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19963 unlink the temporary file if Fcall_process didn't create it in the
19965 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19966 child process will be redirected to a file specified with `:file'.
19967 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19968 cue to call_process_cleanup not to close that handle.
19970 2011-05-07 Ben Key <bkey76@gmail.com>
19972 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19973 one of two shell specific rules, either bootstrap-temacs-CMD or
19974 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19975 to the previous implementation of the bootstrap-temacs rule.
19976 The bootstrap-temacs-CMD rule is similar to the previous
19977 implementation of the bootstrap-temacs rule except that it
19978 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19981 These changes, along with some changes to nt/configure.bat,
19982 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19983 earlier fix to add support for --cflags and --ldflags options
19984 that include quotes so that it works whether make uses cmd or
19987 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19989 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19990 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19992 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19993 a string. Handle both cases.
19994 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19995 (Fdbus_register_method): Use Qinvalid_function.
19997 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19999 * makefile.w32-in: Update dependencies.
20000 (LISP_H): Add inttypes.h and stdin.h.
20001 (PROCESS_H): Add unistd.h.
20003 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20005 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20006 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20008 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20010 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20012 * term.c (vfatal): Remove stray call to va_end.
20013 It's not needed and the C Standard doesn't allow it here anyway.
20015 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20016 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20018 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20021 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20023 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20025 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20027 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20029 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20031 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20032 * charset.c (Fdefine_charset_internal): Don't initialize
20033 charset.code_space[15]. The value was garbage, on hosts with
20034 32-bit int (Bug#8600).
20036 * lread.c (read_integer): Be more consistent with string-to-number.
20037 Use string_to_number to do the actual conversion; this avoids
20038 rounding errors and fixes some other screwups. Without this fix,
20039 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20040 (digit_to_number): Move earlier, for benefit of read_integer.
20041 Return -1 if the digit is out of range for the base, -2 if it is
20042 not a digit in any supported base. (Bug#8602)
20044 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20046 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20047 to match comment at start of function. This also removes a
20048 GCC warning about overflow in a 32+64-bit port.
20050 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20052 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20053 Reported by Stefan Monnier in
20054 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20055 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20056 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20058 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20059 (EMACS_UINTPTR): Likewise, with uintptr_t.
20061 * lisp.h: Prefer 64-bit EMACS_INT if available.
20062 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20063 on 32-bit hosts that have 64-bit int, so that they can access
20065 However, temporarily disable this change unless the temporary
20066 symbol WIDE_EMACS_INT is defined.
20068 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20070 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20071 This removes an assumption that EMACS_INT and long are the same
20072 width as pointers. The assumption is true for Emacs porting targets
20073 now, but we want to make other targets possible.
20074 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20075 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20076 In the rest of the code, change types of integers that hold casted
20077 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20078 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20079 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20080 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20081 No need to cast type when ORing.
20082 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20083 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20084 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20085 assume EMACS_INT is the same width as char *.
20086 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20087 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20088 Remove no-longer-needed casts.
20089 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20090 (xg_tool_bar_help_callback, xg_make_tool_item):
20091 Use EMACS_INTPTR to hold an integer
20092 that will be cast to void *; this can avoid a GCC warning
20093 if EMACS_INT is not the same width as void *.
20094 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20095 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20096 (current_message_1, set_message_1):
20097 Use a local to convert to proper width without a cast.
20098 * xmenu.c (dialog_selection_callback): Likewise.
20100 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20101 Also, don't assume VALBITS / RAND_BITS is less than 5,
20102 and don't rely on undefined behavior when shifting a 1 left into
20104 * lisp.h (get_random): Change signature to match.
20106 * lread.c (hash_string): Use size_t, not int, for hash computation.
20107 Normally we prefer signed values; but hashing is special, because
20108 it's better to use unsigned division on hash table sizes so that
20109 the remainder is nonnegative. Also, size_t is the natural width
20110 for hashing into memory. The previous code used 'int', which doesn't
20111 retain enough info to hash well into very large tables.
20112 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20114 * dbusbind.c: Don't possibly lose pointer info when converting.
20115 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20116 Use XPNTR rather than XHASH, so that the high-order bits of
20117 the pointer aren't lost when converting through void *.
20119 * eval.c (Fautoload): Don't double-shift a pointer.
20121 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20123 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20125 * gnutls.c (DEF_GNUTLS_FN):
20126 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20128 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20130 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20133 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20135 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20136 New version that can reserve upto 2GB of heap space.
20138 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20140 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20142 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20144 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20145 `gnutls_certificate_set_x509_key_file'.
20147 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20149 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20150 Update dependencies.
20152 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20154 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20155 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20156 Remove unused parameter `fildes'.
20157 * process.c (read_process_output, send_process): Don't pass it.
20159 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20161 Fix previous change: the library cache is defined in w32.c.
20162 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20163 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20165 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20167 Implement dynamic loading of GnuTLS on Windows.
20169 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20170 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20171 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20174 * gnutls.c (Qgnutls_dll): Define.
20175 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20176 (gnutls_*): Declare function pointers.
20177 (init_gnutls_functions): New function to initialize function pointers.

20180 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20181 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20182 (emacs_gnutls_write, emacs_gnutls_read)
20183 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20184 (Fgnutls_available_p): New function.
20185 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20197 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20198 (w32_delayed_load): Move from image.c. When loading a library, record
20199 its filename in the :loaded-from property of the library id.
20200 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20201 Initialize and staticpro them.
20202 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20204 * process.c: Include lisp.h before w32.h, not after.
20205 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20206 instead of gnutls_record_check_pending.
20208 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20210 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20212 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20213 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20216 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20218 * xterm.c (x_set_frame_alpha): Do not set property on anything
20219 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20221 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20223 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20225 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20227 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

20237 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
20239 * callproc.c: Indentation fixup.
20241 * sysdep.c (wait_for_termination_1): Make static.
20242 (wait_for_termination, interruptible_wait_for_termination):
20243 Move after wait_for_termination_1.
20245 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20247 * sysdep.c (interruptible_wait_for_termination): New function
20248 which is like wait_for_termination, but allows keyboard
20251 * callproc.c (Fcall_process): Add (:file "file") as an option for
20253 (Fcall_process_region): Ditto.
20255 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20257 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20258 rather than `XVECTOR (FOO)->size'.
20260 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20261 inttypes.h, as a gnulib replacement is used if it not available in
20264 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20266 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20267 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20268 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20270 * coding.c (coding_alloc_by_realloc): Error out if destination
20271 will grow beyond MOST_POSITIVE_FIXNUM.
20272 (decode_coding_emacs_mule): Abort if there isn't enough place in
20273 charbuf for the composition carryover bytes. Reserve an extra
20274 space for up to 2 characters produced in a loop.
20275 (decode_coding_iso_2022): Abort if there isn't enough place in
20276 charbuf for the composition carryover bytes.

20283 %llo or %llx format is passed. (Bug#8545)
20285 * window.c (window_scroll_line_based): Use a marker instead of
20286 simple variables to record original value of point. (Bug#7952)
20288 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20289 produced by %s or %c overflows available buffer space. (Bug#8545)
20291 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20293 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20322 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20324 * makefile.w32-in: Update dependencies.
20326 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20328 Improve `doprnt' and its usage. (Bug#8545)
20329 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20330 `format_end'. Remove support for %l as a conversion specifier.
20331 Don't use xrealloc. Improve diagnostics when the %l size modifier
20332 is used. Update the commentary.
20334 * eval.c (verror): Simplify calculation of size_t.
20336 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20339 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20341 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20344 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20346 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20347 This makes this file independent of the recent pseudovector change.
20349 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20351 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20353 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20354 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20355 Remove unused local.
20356 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20358 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20359 GCC 4.6.0 optimizes based on type-based alias analysis.
20360 For example, if b is of type struct buffer * and v of type struct
20361 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20362 != &v->size, and therefore "v->size = 1; b->size = 2; return
20363 v->size;" must therefore return 1. This assumption is incorrect
20364 for Emacs, since it type-puns struct Lisp_Vector * with many other
20365 types. To fix this problem, this patch adds a new type struct
20366 vectorlike_header that documents the constraints on layout of vectors
20367 and pseudovectors, and helps optimizing compilers not get fooled
20368 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20369 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20370 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20372 (XSETPVECTYPE): Rewrite in terms of new macro.
20373 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20374 This is a bit clearer, and further avoids the possibility of
20375 undesirable aliasing.
20376 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20377 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20378 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20379 since Lisp_Subr is a special case (no "next" field).
20380 (ASIZE): Now uses header.size rather than size.
20381 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20382 to avoid the hassle of writing XVECTOR (foo)->header.size.
20383 (struct vectorlike_header): New type.
20384 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20385 object, to help avoid aliasing.
20386 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20387 (SUBRP): Likewise, since Lisp_Subr is a special case.
20388 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20389 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20390 (struct Lisp_Hash_Table): Combine first two members into a single
20391 struct vectorlike_header member. All uses of "size" and "next" members
20392 changed to be "header.size" and "header.next".
20393 * buffer.h (struct buffer): Likewise.
20394 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20395 * frame.h (struct frame): Likewise.
20396 * process.h (struct Lisp_Process): Likewise.
20397 * termhooks.h (struct terminal): Likewise.
20398 * window.c (struct save_window_data, struct saved_window): Likewise.
20399 * window.h (struct window): Likewise.
20400 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20401 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20402 * buffer.c (init_buffer_once): Likewise.
20403 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20405 * process.c (Fformat_network_address): Use local var for size,
20408 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20410 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20411 * data.c (atof): Remove decl; no longer used or needed.
20412 (digit_to_number): Move to lread.c.
20413 (Fstring_to_number): Use new string_to_number function, to be
20414 consistent with how the Lisp reader treats infinities and NaNs.
20415 Do not assume that floating-point numbers represent EMACS_INT
20416 without losing information; this is not true on most 64-bit hosts.
20417 Avoid double-rounding errors, by insisting on integers when
20418 parsing non-base-10 numbers, as the documentation specifies.
20419 * lisp.h (string_to_number): New decl, replacing ...
20420 (isfloat_string): Remove.
20421 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20422 (read1): Do not accept +. and -. as integers; this
20423 appears to have been a coding error. Similarly, do not accept
20424 strings like +-1e0 as floating point numbers. Do not report
20425 overflow for integer overflows unless the base is not 10 which
20426 means we have no simple and reliable way to continue.
20427 Break out the floating-point parsing into a new
20428 function string_to_number, so that Fstring_to_number parses
20429 floating point numbers consistently with the Lisp reader.
20430 (digit_to_number): Move here from data.c. Make it static inline.
20431 (E_CHAR, EXP_INT): Remove, replacing with ...
20432 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20433 (string_to_number): New function, replacing isfloat_string.
20434 This function checks for valid syntax and produces the resulting
20435 Lisp float number too. Rework it so that string-to-number
20436 no longer mishandles examples like "1.0e+". Use strtoumax,
20437 so that overflow for non-base-10 numbers is reported only when
20438 there's no portable and simple way to convert to floating point.
20440 * textprop.c (set_text_properties_1): Rewrite for clarity,
20441 and to avoid GCC warning about integer overflow.
20443 * intervals.h (struct interval): Use EMACS_INT for members
20444 where EMACS_UINT might cause problems. See
20445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20446 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20447 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20449 (offset_intervals): Tell GCC not to worry about length overflow
20450 when negating a negative length.
20452 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20453 (overrun_check_free): Likewise.
20455 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20456 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20459 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20460 (gnutls_make_error): Rename local to avoid shadowing.
20461 (gnutls_emacs_global_deinit): ifdef out; not used.
20462 (Fgnutls_boot): Use const for pointer to readonly storage.
20463 Comment out unused local. Fix pointer signedness problems.
20465 * lread.c (openp): Don't stuff size_t into an 'int'.
20466 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20467 about possible signed overflow.
20469 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20470 (GDK_KEY_g): Don't define if already defined.
20471 (xg_prepare_tooltip): Avoid pointer signedness problem.
20472 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20474 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20475 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20477 * xfns.c (Fx_window_property): Simplify a bit,
20478 to make a bit faster and to avoid GCC 4.6.0 warning.
20479 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20481 * fns.c (internal_equal): Don't assume size_t fits in int.
20483 * alloc.c (compact_small_strings): Tighten assertion a little.
20485 Replace pEd with more-general pI, and fix some printf arg casts.
20486 * lisp.h (pI): New macro, generalizing old pEd macro to other
20487 conversion specifiers. For example, use "...%"pI"d..." rather
20488 than "...%"pEd"...".
20489 (pEd): Remove. All uses replaced with similar uses of pI.
20490 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20491 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20492 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20493 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20494 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20495 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20496 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20498 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20499 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20500 * print.c (safe_debug_print, print_object): Likewise.
20501 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20503 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20504 avoiding the 0 flag, which is not portable.
20505 * process.c (Fmake_network_process): Use pI to avoid cast.
20506 * region-cache.c (pp_cache): Likewise.
20507 * xdisp.c (decode_mode_spec): Likewise.
20508 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20509 behavior on 64-bit hosts with printf arg.
20510 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20511 (x_stop_queuing_selection_requests): Likewise.
20512 (x_get_window_property): Don't truncate byte count to an 'int'
20515 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20516 here, since it parses constructs like leading '-' and spaces,
20517 which are not wanted; and it overflows with large numbers.
20518 Instead, simply match F[0-9]+, which is what is wanted anyway.
20520 * alloc.c: Remove unportable assumptions about struct layout.
20521 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20522 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20523 (allocate_vectorlike, make_pure_vector): Use the new macros,
20524 plus offsetof, to remove unportable assumptions about struct layout.
20525 These assumptions hold on all porting targets that I know of, but
20526 they are not guaranteed, they're easy to remove, and removing them
20527 makes further changes easier.
20529 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20530 This doesn't fix a bug but makes the code clearer.
20531 (string_overrun_cookie): Now const. Use initializers that
20532 don't formally overflow signed char, to avoid warnings.
20533 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20534 can cause Emacs to crash when string overrun checking is enabled.
20535 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20536 multiple of sizeof (EMACS_INT); it need not be, if
20537 alignof(EMACS_INT) < sizeof (EMACS_INT).
20538 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20540 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20547 supposed to be handshaking. (Bug#8556)
20548 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20550 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

20567 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20569 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20570 "cast to pointer from integer of different size".
20572 Improve doprnt and its use in verror. (Bug#8545)
20573 * doprnt.c (doprnt): Document the set of format control sequences
20574 supported by the function. Use SAFE_ALLOCA instead of always
20577 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20578 is one byte too soon. Don't use xrealloc; instead xfree and
20581 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20583 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20586 * gnutls.c: Renamed global_initialized to
20587 gnutls_global_initialized. Added internals for the
20588 :verify-hostname-error, :verify-error, and :verify-flags
20589 parameters of `gnutls-boot' and documented those parameters in the
20590 docstring. Start callback support.
20591 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20592 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20593 on error. Return error code.

20653 changes in globals.h immediately force recompilation.
20654 (TAGS): Depend on $(CURDIR)/m/intel386.h and

20665 * doprnt.c: Include limits.h.
20666 (SIZE_MAX): New macro.
20667 (doprnt): Return a size_t value. 2nd arg is now size_t.
20668 Many local variables are now size_t instead of int or unsigned.
20669 Improve overflow protection. Support `l' modifier for integer
20670 conversions. Support %l conversion. Don't assume an EMACS_INT
20671 argument for integer conversions and for %c.
20673 * lisp.h (doprnt): Restore prototype.
20675 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
20676 $(SRC)/character.h.
20678 * Makefile.in (base_obj): Add back doprnt.o.
20680 * deps.mk (doprnt.o): Add back prerequisites.
20681 (callint.o): Depend on character.h.
20683 * eval.c (internal_lisp_condition_case): Include the handler
20684 representation in the error message.

20690 * callint.c (Fcall_interactively): When displaying error message
20691 about invalid control letter, pass the character's codepoint, not
20692 a pointer to its multibyte form. Improve display of the character
20693 in octal and display also its hex code.
20695 * character.c (char_string): Use %x to display the (unsigned)
20696 codepoint of an invalid character, to avoid displaying a bogus
20699 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20700 `error', not SYMBOL_NAME itself.
20702 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20703 character arguments to `error'.
20705 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20706 to `error' in error message about FINAL_CHAR argument. Make sure
20707 FINAL_CHAR is a character, and use %c when it is passed as

20774 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
20775 by pacifying GCC about it. Maybe it's time to retire it?
20776 * xfaces.c (USG, __TIMEVAL__): Likewise.
20778 * dispextern.h (struct redisplay_interface): Rename param
20779 to avoid shadowing.
20780 * termhooks.h (struct terminal): Likewise.
20781 * xterm.c (xembed_send_message): Likewise.
20783 * insdel.c (make_gap_smaller): Define only if
20784 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
20786 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
20789 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
20790 so that we aren't warned about unused symbols.
20792 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
20794 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

20807 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
20809 * xmenu.c (menu_help_callback): Pointer type fixes.

20827 compatible char. Avoid the old compiler warnings about
20828 out-of-range initializers by using, for example, '\xab' rather
20831 * xgselect.c (xgselect_initialize): Check vs interface
20832 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

20897 * nsfont.m: Fixed bugs in ns_get_family and
20898 ns_descriptor_to_entity that were caused by using free to
20899 deallocate memory blocks that were allocated by xmalloc (via
20900 xstrdup). This caused Emacs to crash when compiled with
20901 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20902 --enable-checking=xmallocoverrun). xfree is now used to
20903 deallocate these memory blocks.

21299 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
21300 * xmenu.c, xselect.c:
21301 Declare Q* vars static if they are not used in other modules.
21302 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
21303 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
21304 Remove decls of unexported vars.
21305 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21307 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21309 Make Emacs functions such as Fatom 'static' by default.
21310 This makes it easier for human readers (and static analyzers)
21311 to see whether these functions can be called from other modules.
21312 DEFUN now defines a static function. To make the function external
21313 so that it can be used in other C modules, use the new macro DEFUE.
21314 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21315 (Finit_image_library):
21316 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21317 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21318 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21319 Remove decls, since these functions are now static.
21320 (Funintern, Fget_internal_run_time): New decls, since these functions
21321 were already external.
21323 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21324 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21330 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21331 Mark functions with DEFUE instead of DEFUN,
21332 if they are used in other modules.
21333 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21334 decls for now-static functions.
21335 * buffer.h (Fdelete_overlay): Remove decl.
21336 * callproc.c (Fgetenv_internal): Mark as internal.
21337 * composite.c (Fremove_list_of_text_properties): Remove decl.

21341 * doc.c (Fdocumntation_property): New forward static decl.
21342 * eval.c (Ffetch_bytecode): New forward static decl.
21343 (Funintern): Remove extern decl; now in .h file where it belongs.
21344 * fileio.c (Fmake_symbolic_link): New forward static decl.
21345 * image.c (Finit_image_library): New forward static decl.
21346 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21347 * intervals.h (Fprevious_property_change):
21348 (Fremove_list_of_text_properties): Remove decls.
21349 * keyboard.c (Fthis_command_keys): Remove decl.
21350 (Fcommand_execute): New forward static decl.
21351 * keymap.c (Flookup_key): New forward static decl.
21352 (Fcopy_keymap): Now static.
21353 * keymap.h (Flookup_key): Remove decl.
21354 * process.c (Fget_process): New forward static decl.
21355 (Fprocess_datagram_address): Mark as internal.

21366 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21368 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21371 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21373 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21374 when at ZV. (Bug#8487)
21376 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21378 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21380 * keyboard.c (parse_tool_bar_item): Likewise.
21381 * sound.c (sound_cleanup, alsa_close): Likewise.
21382 * termcap.c (tgetent): Likewise.
21383 * xfns.c (x_default_font_parameter): Likewise.
21384 * xsettings.c (read_and_apply_settings): Likewise.
21386 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21387 (overrun_check_free): Protoize.
21389 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21391 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21392 since callers should never pass a negative size.
21393 Change the signature to match that of plain 'read' and 'write'; see
21394 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21395 * lisp.h: Update prototypes of emacs_write and emacs_read.
21397 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21399 * xdisp.c (redisplay_window): Don't try to determine the character
21400 position of the scroll margin if the window start point w->startp
21401 is outside the buffer's accessible region. (Bug#8468)
21403 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21405 Fix write-region and its subroutines for buffers > 2GB.
21406 * fileio.c (a_write, e_write): Modify declaration of arguments and
21407 local variables to support buffers larger than 2GB.
21408 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21410 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21411 argument, local variables, and return value.
21413 * lisp.h: Update prototypes of emacs_write and emacs_read.
21415 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21417 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21419 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21421 Fix more problems found by GCC 4.6.0's static checks.
21423 * xdisp.c (vmessage): Use a better test for character truncation.
21425 * charset.c (load_charset_map): <, not <=, for optimization,
21426 and to avoid potential problems with integer overflow.
21427 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21428 * casetab.c (set_identity, shuffle): Likewise.
21429 * editfns.c (Fformat): Likewise.
21430 * syntax.c (skip_chars): Likewise.
21432 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21433 This also lets GCC 4.6.0 generate slightly better loop code.
21435 * callint.c (Fcall_interactively): <, not <=, for optimization.
21436 (Fcall_interactively): Count the number of arguments produced,
21437 not the number of arguments given. This is simpler and lets GCC
21438 4.6.0 generate slightly better code.
21440 * ftfont.c: Distingish more carefully between FcChar8 and char.
21441 The previous code passed unsigned char * to a functions like
21442 strlen and xstrcasecmp that expect char *, which does not
21443 conform to the C standard.
21444 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21445 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21446 char * when the C standard requires it.
21448 * keyboard.c (read_char): Remove unused var.
21450 * eval.c: Port to Windows vsnprintf (Bug#8435).
21451 Include <limits.h>.
21452 (SIZE_MAX): Define if the headers do not.
21453 (verror): Do not give up if vsnprintf returns a negative count.
21454 Instead, grow the buffer. This ports to Windows vsnprintf, which
21455 does not conform to C99. Problem reported by Eli Zaretskii.
21456 Also, simplify the allocation scheme, by avoiding the need for
21457 calling realloc, and removing the ALLOCATED variable.
21459 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21461 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21462 But keep the doprint source code for now, as we might revamp it
21463 and use it again (Bug#8435).
21464 * lisp.h (doprnt): Remove.
21465 * Makefile.in (base_obj): Remove doprnt.o.
21466 * deps.mk (doprnt.o): Remove.
21468 error: Print 32- and 64-bit integers portably (Bug#8435).
21469 Without this change, on typical 64-bit hosts error ("...%d...", N)
21470 was used to print both 32- and 64-bit integers N, which relied on
21471 undefined behavior.
21472 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21473 * lisp.h (error, verror): Mark as printf-like functions.
21474 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21475 Report overflow in size calculations when allocating printf buffer.
21476 Do not truncate output string at its first null byte.
21477 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21478 Truncate the output at a character boundary, since vsnprintf does not
21480 * charset.c (check_iso_charset_parameter): Convert internal
21481 character to string before calling 'error', since %c now has the
21483 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21484 overflow when computing char to be passed to 'error'. Do not
21485 pass Lisp_Object to 'error'; pass the integer instead.
21486 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21487 formatted with plain %d.
21489 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21491 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21493 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21495 * xterm.c (x_catch_errors): Remove duplicate declaration.
21497 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21499 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21501 2011-04-10 Jim Meyering <meyering@redhat.com>
21503 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21504 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21505 return ssize_t not "int", and use size_t as the buffer length.
21506 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21507 * gnutls.h: Update declarations.
21508 * process.c (read_process_output): Use ssize_t, to match.
21509 (send_process): Likewise.
21511 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21513 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21515 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21517 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21518 Use unsigned char, to match FcChar8 type definition.
21520 * xterm.c (handle_one_xevent):
21521 * xmenu.c (create_and_show_popup_menu):
21522 * xselect.c (x_decline_selection_request)
21523 (x_reply_selection_request): Avoid type-punned deref of X events.
21525 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21527 Fix some uses of `int' instead of EMACS_INT.
21528 * search.c (string_match_1, fast_string_match)
21529 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21530 (scan_buffer, find_next_newline_no_quit)
21531 (find_before_next_newline, search_command, Freplace_match)
21532 (Fmatch_data): Make some `int' variables be EMACS_INT.
21534 * xdisp.c (display_count_lines): 3rd argument and return value now
21535 EMACS_INT. All callers changed.
21536 (pint2hrstr): Last argument is now EMACS_INT.
21538 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21539 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21540 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21541 (decode_coding_utf_16, decode_coding_emacs_mule)

21543 (decode_coding_ccl, decode_coding_charset)
21544 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21545 (decode_coding_iso_2022, decode_coding_emacs_mule)
21546 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21547 <char_offset, last_offset>: Declare EMACS_INT.

21549 (encode_coding_emacs_mule, encode_invocation_designation)
21550 (encode_designation_at_bol, encode_coding_iso_2022)
21551 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21552 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21554 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21555 (encode_invocation_designation): Last argument P_NCHARS is now
21557 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21558 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21560 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21563 * ccl.c (Fccl_execute_on_string): Declare some variables
21566 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21568 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21570 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21572 * process.c (Fformat_network_address): Doc fix.
21574 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21576 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21578 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21580 * keyboard.c (read_char): Call Lisp function help-form-show,
21581 instead of using internal_with_output_to_temp_buffer.
21582 (Qhelp_form_show): New var.
21583 (syms_of_keyboard): Use DEFSYM macro.
21585 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21589 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21591 * process.c (Flist_processes): Remove to Lisp.
21592 (list_processes_1): Delete.
21594 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21596 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21598 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21600 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21602 Fix more problems found by GCC 4.6.0's static checks.
21604 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21606 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21608 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21610 * xdisp.c (vmessage): Mark as a printf-like function.
21612 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21614 * sound.c (sound_warning): Don't crash if arg contains a printf format.

21619 to system-supplied API.
21621 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21623 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21624 This avoids several warnings with gcc -Wstrict-overflow.
21625 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21626 directly, rather than having caller test rule sign. This avoids
21627 some unnecessary tests.
21628 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21629 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21630 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21632 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21633 (xfont_open): Avoid unnecessary tests.
21635 * composite.c (composition_gstring_put_cache): Use unsigned integer.

21644 by using the new macro.
21646 * textprop.c (set_text_properties_1): Change while to do-while,
21647 since the condition is always true at first.
21649 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21650 (interval_deletion_adjustment): Return unsigned value.
21653 * process.c (list_processes_1, create_pty, read_process_output):

21663 (update_syntax_table): Use unsigned instead of int.
21665 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21666 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21667 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21669 * print.c (print_error_message): Avoid int overflow.
21671 * font.c (font_list_entities): Redo for clarity,
21672 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21674 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21675 (font_score): Avoid potential overflow in diff calculation.
21677 * fns.c (substring_both): Remove var that is set but not used.
21678 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21680 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21682 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21683 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21684 can always succeed if overflow has undefined behavior.
21686 * search.c (boyer_moore, wordify): Remove vars set but not used.
21687 (wordify): Omit three unnecessary tests.
21689 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21690 All callers changed. This avoids the need for an unused var.
21692 * casefiddle.c (casify_region): Remove var that is set but not used.
21694 * dired.c (file_name_completion): Remove var that is set but not used.

21698 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21699 (Finsert_file_contents): Remove unnecessary code checking fd.
21701 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21702 Check for integer overflow on size calculations.
21704 * buffer.c (Fprevious_overlay_change): Remove var that is set
21707 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21708 Remove vars that are set but not used.
21709 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21710 (timer_check_2): Mark vars as initialized.
21712 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21714 * image.c (lookup_image): Remove var that is set but not used.
21715 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21717 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21718 that are set but not used.
21720 * xfns.c (make_invisible_cursor): Don't return garbage
21721 if XCreateBitmapFromData fails (Bug#8410).
21723 * xselect.c (x_get_local_selection, x_handle_property_notify):
21724 Remove vars that are set but not used.
21726 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21727 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21729 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21730 Remove var that is set but not used.
21731 (scroll_bar_windows_size): Now size_t, not int.
21732 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21733 Check for overflow.
21735 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21736 (map_tty_color) [!defined MSDOS]: Likewise.
21738 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21740 * coding.c: Remove vars that are set but not used.
21741 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

21748 that is set but not used.
21750 * print.c (print_object): Remove var that is set but not used.
21752 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21753 The gnulib version avoids calling malloc in the usual case,
21754 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21755 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21756 * filelock.c (current_lock_owner): Likewise.
21757 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21758 * sysdep.c: Include allocator.h, careadlinkat.h.
21759 (emacs_no_realloc_allocator): New static constant.
21760 (emacs_readlink): New function.
21761 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21762 ../lib/careadlinkat.h.
21764 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21766 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

21783 (get_per_char_metric): Remove parameter `f', unused since
21784 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21788 do not dereference NULL upon failed strdup
21789 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21790 (ns_get_family): Likewise.
21792 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21794 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21796 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21798 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21801 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21803 Add lexical binding.
21805 * window.c (Ftemp_output_buffer_show): New fun.
21806 (Fsave_window_excursion):
21807 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

21812 Bind Qinternal_interpreter_environment.
21813 (Feval_buffer): Bind Qlexical_binding.
21814 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21816 (syms_of_lread): Declare `lexical-binding'.
21818 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21820 * keyboard.c (eval_dyn): New fun.
21821 (menu_item_eval_property): Use it.
21823 * image.c (parse_image_spec): Use Ffunctionp.
21825 * fns.c (concat, mapcar1): Accept byte-code-functions.
21827 * eval.c (Fsetq): Handle lexical vars.
21828 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21829 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21830 (FletX, Flet): Obey lexical binding.
21831 (Fcommandp): Handle closures.
21832 (Feval): New `lexical' arg.
21833 (eval_sub): New function extracted from Feval. Use it almost
21834 everywhere where Feval was used. Look up vars in lexical env.
21836 (Ffunctionp): Move from subr.el.
21837 (Ffuncall): Handle closures.
21838 (apply_lambda): Remove `eval_flags'.
21839 (funcall_lambda): Handle closures and new byte-code-functions.
21840 (Fspecial_variable_p): New function.
21841 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21842 but without exporting it to Lisp.
21844 * doc.c (Fdocumentation, store_function_docstring):
21845 * data.c (Finteractive_form): Handle closures.
21847 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21850 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21852 (exec_byte_code): New function extracted from Fbyte_code to handle new
21853 calling convention for byte-code-functions. Add new byte-codes.
21855 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21857 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21859 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21861 * xdisp.c (redisplay_internal): Fix prototype.
21863 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21865 * xdisp.c (SCROLL_LIMIT): New macro.
21866 (try_scrolling): Use it when setting scroll_limit.
21867 Limit scrolling to 100 screen lines.
21868 (redisplay_window): Even when falling back on "recentering",
21869 position point in the window according to scroll-conservatively,
21870 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21872 (try_scrolling): When point is above the window, allow searching
21873 as far as scroll_max, or one screenful, to compute vertical
21874 distance from PT to the scroll margin position. This prevents
21875 try_scrolling from unnecessarily failing when
21876 scroll-conservatively is set to a value slightly larger than the
21877 window height. Clean up the case of PT below the margin at bottom
21878 of window: scroll_max can no longer be INT_MAX. When aggressive
21879 scrolling is in use, don't let point enter the opposite scroll
21880 margin as result of the scroll.
21881 (syms_of_xdisp) <scroll-conservatively>: Document the
21882 threshold of 100 lines for never-recentering scrolling.
21884 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

21889 (message_log_check_duplicate): Remove parameters `prev_bol' and
21890 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21891 (redisplay_internal): Remove parameter `preserve_echo_area',
21892 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21894 * indent.c (Fvertical_motion):
21895 * window.c (window_scroll_pixel_based, Frecenter):
21896 Don't pass `need_y_p' to `move_it_by_lines'.
21898 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21900 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21901 steal a few bits to be more compact.
21902 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21903 Remove unneeded casts.
21905 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21907 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21909 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21910 binding" message (bug#7967).
21912 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21914 Fix more problems found by GCC 4.6.0's static checks.
21916 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21917 Remove unused local var.
21919 * editfns.c (Fmessage_box): Remove unused local var.
21921 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21922 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21923 Omit unused local vars.
21924 * window.c (shrink_windows): Omit unused local var.
21925 * menu.c (digest_single_submenu): Omit unused local var.
21926 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21927 Omit unused local var.
21929 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21930 Don't assume string length fits in int.
21931 (keyremap_step, read_key_sequence): Use size_t for sizes.
21932 (read_key_sequence): Don't check last_real_key_start redundantly.
21934 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21935 instead of alloca (Bug#8344).
21937 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21938 (Fbacktrace_frame): Don't assume nframes fits in int.
21940 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21947 * cm.c (calccost): Turn while-do into do-while, for clarity.
21949 * keyboard.c (syms_of_keyboard): Use the same style as later
21950 in this function when indexing through an array. This also
21951 works around GCC bug 48267.
21953 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21955 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21957 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21958 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21960 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21961 This avoids undefined behavior on integer overflow, and is a bit
21962 more convenient anyway since it is compared to a size_t variable.
21964 Variadic C functions now count arguments with size_t, not int.
21965 This avoids an unnecessary limitation on 64-bit machines, which
21966 caused (substring ...) to crash on large vectors (Bug#8344).

21976 * fns.c (concat): Likewise.
21977 * frame.c (x_set_frame_parameters): Likewise.
21978 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21979 0 if not found, not -1. All callers changed.
21981 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21982 (stack_copy_size): Now size_t, not int.
21983 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21985 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21987 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21988 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22004 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22005 don't set the hook to nil, but remove the offending function instead.
22006 (Qcommand_hook_internal): Remove, unused.
22007 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22008 Vcommand_hook_internal.
22010 * eval.c (enum run_hooks_condition): Remove.
22011 (funcall_nil, funcall_not): New functions.
22012 (run_hook_with_args): Call each function through a `funcall' argument.
22013 Remove `cond' argument, now redundant.

22026 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

22176 2011-03-23 Julien Danjou <julien@danjou.info>
22178 * term.c (Fsuspend_tty, Fresume_tty):
22179 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22180 * window.c (temp_output_buffer_show):
22181 * insdel.c (signal_before_change):
22182 * frame.c (Fhandle_switch_frame):
22183 * fileio.c (Fdo_auto_save):
22184 * emacs.c (Fkill_emacs):
22185 * editfns.c (save_excursion_restore):
22186 * cmds.c (internal_self_insert):
22187 * callint.c (Fcall_interactively):
22188 * buffer.c (Fkill_all_local_variables):
22189 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22191 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22192 unconditionally since it does the check itself.
22194 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22196 Fix more problems found by GCC 4.5.2's static checks.
22198 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22199 the first time through the loop, since we know p0 < p1 then.
22200 This also avoids a gcc -Wstrict-overflow warning.
22202 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22203 leading to a memory leak, possible in functions like
22204 load_charset_map_from_file that can allocate an unbounded number
22205 of objects (Bug#8318).
22207 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22208 that could (at least in theory) be that large.
22210 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22211 This is less likely to overflow, and avoids undefined behavior if
22212 overflow does occur. All callers changed. Use strtoul to scan
22213 for the unsigned long integer.
22214 (pint2hrstr): Simplify and tune code slightly.
22215 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22217 * scroll.c (do_scrolling): Work around GCC bug 48228.
22218 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22220 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22221 This also avoids a warning with gcc -Wstrict-overflow.
22222 (validate_x_resource_name): Simplify count usage.
22223 This also avoids a warning with gcc -Wstrict-overflow.
22225 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22228 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22230 * process.c (Fmake_network_process): Use socklen_t, not int,
22231 where POSIX says socklen_t is required in portable programs.
22232 This fixes a porting bug on hosts like 64-bit HP-UX, where
22233 socklen_t is wider than int (Bug#8277).
22234 (Fmake_network_process, server_accept_connection):
22235 (wait_reading_process_output, read_process_output):
22238 * process.c: Rename or move locals to avoid shadowing.
22239 (list_processes_1, Fmake_network_process):
22240 (read_process_output_error_handler, exec_sentinel_error_handler):
22241 Rename or move locals.
22242 (Fmake_network_process): Define label "retry_connect" only if needed.
22243 (Fnetwork_interface_info): Fix pointer signedness.
22244 (process_send_signal): Add cast to avoid pointer signedness problem.
22245 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22246 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22248 Make tparam.h and terminfo.c consistent.
22249 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22250 Include tparam.h instead, since it declares them.
22251 * cm.h (PC): Remove extern decl; tparam.h now does this.
22252 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22253 * terminfo.c: Include tparam.h, to check interfaces.
22254 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22255 (tparam): Adjust signature to match interface in tparam.h;
22256 this removes some undefined behavior. Check that outstring and len
22257 are zero, which they always are with Emacs.
22258 * tparam.h (PC, BC, UP): New extern decls.
22260 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22261 (xftfont_open): Rename locals to avoid shadowing.
22263 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22264 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22265 (OTF_TAG_SYM): Omit macro if not needed.
22266 (ftfont_list): Remove unused local.
22267 (get_adstyle_property, ftfont_pattern_entity):
22268 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22269 Rename locals to avoid shadowing.

22273 * xml.c (make_dom): Now static.
22275 * composite.c (composition_compute_stop_pos): Rename local to
22277 (composition_reseat_it): Remove unused locals.
22278 (find_automatic_composition, composition_adjust_point): Likewise.
22279 (composition_update_it): Mark var as initialized.
22280 (find_automatic_composition): Mark vars as initialized,
22281 with a FIXME (Bug#8290).
22283 character.h: Rename locals to avoid shadowing.
22284 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22285 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22286 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22287 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22288 to avoid shadowing.
22290 * textprop.c (property_change_between_p): Remove; unused.
22292 * intervals.c (interval_start_pos): Now static.
22294 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22297 Rename locals to avoid shadowing.
22299 * sound.c (wav_play, au_play, Fplay_sound_internal):
22300 Fix pointer signedness.
22301 (alsa_choose_format): Remove unused local var.
22302 (wav_play): Initialize a variable to 0, to prevent undefined
22303 behavior (Bug#8278).
22305 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22307 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22309 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22310 clobbering (Bug#8298).
22311 * sysdep.c (sys_subshell): Likewise.
22312 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22314 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22315 This should get cleaned up, so that child_setup has the
22316 same signature on all platforms.
22318 * callproc.c (call_process_cleanup): Now static.
22319 (relocate_fd): Rename locals to avoid shadowing.
22321 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22323 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22324 not to be necessary, and produces flickering.
22326 2011-03-20 Glenn Morris <rgm@gnu.org>
22328 * config.in: Remove file.
22330 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22332 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22333 are now in src/globals.h.
22334 (syms_of_minibuf): Remove spurious & from previous change.
22336 2011-03-20 Leo Liu <sdl.web@gmail.com>
22338 * minibuf.c (completing-read-function): New variable.
22339 (completing-read-default): Rename from completing-read.
22340 (completing-read): Call completing-read-function.
22342 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22344 * xfaces.c (Fx_load_color_file):
22345 Read color file from absolute filename (bug#8250).
22347 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22349 * makefile.w32-in: Update dependencies.
22351 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22353 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
22355 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
22357 Fix more problems found by GCC 4.5.2's static checks.
22359 * process.c (make_serial_process_unwind, send_process_trap):
22360 (sigchld_handler): Now static.
22362 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22363 That way, the code declares only the vars that it needs.
22364 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22365 * s/cygwin.h (PTY_ITERATION): Likewise.
22366 * s/darwin.h (PTY_ITERATION): Likewise.

22369 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
22370 * process.c (allocate_pty): Don't declare stb unless it's needed.
22372 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22373 (CONSTANTLIM): Remove; unused.
22374 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22375 Define only if needed.
22377 * unexelf.c (unexec): Name an expression,
22378 to avoid gcc -Wbad-function-cast warning.
22379 Use a different way to cause a compilation error if anyone uses
22380 n rather than nn, a way that does not involve shadowing.
22381 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22383 * deps.mk (unexalpha.o): Remove; unused.
22385 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22386 * unexec.h: New file.
22387 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22388 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22389 Depend on unexec.h.
22390 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22391 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22392 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22393 Change as necessary to match prototype in unexec.h.
22395 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
22397 (back_comment, skip_chars): Mark vars as initialized.
22399 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

22405 * print.c (Fredirect_debugging_output): Fix pointer signedess.
22407 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
22408 warning when compiling print.c.

22411 instead of using an uninitialized var.
22412 (font_sort_entities): Mark var as initialized.
22414 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
22416 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

22428 * floatfns.c (domain_error2): Define only if needed.
22429 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
22431 * alloc.c (mark_backtrace): Move decl from here ...
22432 * lisp.h: ... to here, so that it can be checked.

22440 * callint.c (quotify_arg, quotify_args): Now static.
22441 (Fcall_interactively): Rename locals to avoid shadowing.
22442 Use const pointer when appropriate.
22444 * lisp.h (get_system_name, get_operating_system_release):

22446 * process.c (get_operating_system_release): Move decl to lisp.h.
22447 * xrdb.c (get_system_name): Likewise.
22448 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22449 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22450 some of which prompt warnings from gcc -Wbad-function-cast.
22451 (Fformat_time_string, Fencode_time, Finsert_char):
22452 (Ftranslate_region_internal, Fformat):
22453 Rename or remove local vars to avoid shadowing.
22454 (Ftranslate_region_internal): Mark var as initialized.
22456 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22459 * lisp.h (eassert): Check that the argument compiles, even if
22460 ENABLE_CHECKING is not defined.
22462 * data.c (Findirect_variable): Name an expression, to avoid
22463 gcc -Wbad-function-cast warning.
22464 (default_value, arithcompare, arith_driver, arith_error): Now static.

22471 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
22472 Rename locals to avoid shadowing.
22473 (mark_stack): Move local variables into the #ifdef region where
22475 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22476 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22478 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22479 (GC_STRING_CHARS): Remove; not used.
22480 (Fmemory_limit): Cast sbrk's returned value to char *.
22482 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22483 avoids undefined behavior in theory.
22485 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22487 Use functions, not macros, for up- and down-casing (Bug#8254).
22488 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22489 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22490 to use the following functions instead of these macros.
22491 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22492 EMACS_INT, since callers assume the returned value fits in int.
22493 (upcase1): Likewise, for UPCASE_TABLE.
22494 (uppercasep, lowercasep, upcase): New static inline functions.
22495 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
22496 the race-condition problem in the old DOWNCASE.
22498 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
22499 Rename locals to avoid shadowing.
22500 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
22501 (regex_compile, re_search_2, re_match_2_internal):
22502 Remove unused local vars.
22503 (FREE_VAR): Rewrite so as not to use empty "else",
22504 which gcc can warn about.
22505 (regex_compile, re_match_2_internal): Mark locals as initialized.
22506 (RETALLOC_IF): Define only if needed.
22507 (WORDCHAR_P): Likewise. This one is never needed, but is used
22508 only in a comment talking about a compiler bug, so put inside
22509 the #if 0 of that comment.
22510 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22511 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22514 * search.c (boyer_moore): Rename locals to avoid shadowing.
22515 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
22516 (PREV_CHAR_BOUNDARY): Likewise.

22526 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
22528 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
22529 Rename locals to avoid shadowing.
22530 (Fvertical_motion): Mark locals as initialized.
22532 * casefiddle.c (casify_object, casify_region): Now static.
22533 (casify_region): Mark local as initialized.
22535 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
22537 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22538 New macros, so that the caller can use some names other than
22539 gcpro1, gcpro2, etc.
22540 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22542 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22543 argument, for consistency with GCPRO2_VAR, etc: it is now the
22544 prefix of the variable, not the variable itself. All uses
22546 * dired.c (directory_files_internal, file_name_completion):
22547 Rename locals to avoid shadowing.
22549 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22550 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22551 dired.c's scmp function, had undefined behavior.
22552 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22553 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22554 * buffer.h: ... to here, because these macros use current_buffer,
22555 and the new implementation with inline functions needs to have
22556 current_buffer in scope now, rather than later when the macros
22558 (downcase, upcase1): New static inline functions.
22559 (DOWNCASE, UPCASE1): Reimplement using these functions.
22560 This avoids undefined behavior in expressions like
22561 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22562 from race conditions in accessing the global variables
22563 case_temp1 and case_temp2.
22564 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22565 * lisp.h (case_temp1, case_temp2): Remove their decls.
22566 * character.h (ASCII_CHAR_P): Move from here ...
22567 * lisp.h: ... to here, so that the inline functions mentioned
22568 above can use them.
22570 * dired.c (directory_files_internal_unwind): Now static.
22572 * fileio.c (file_name_as_directory, directory_file_name):
22573 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22575 (file_name_as_directory): Use const pointers when appropriate.
22576 (Fexpand_file_name): Likewise. In particular, newdir might
22577 point at constant storage, so make it a const pointer.
22578 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22579 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22581 (Fset_file_times, Finsert_file_contents, auto_save_error):
22582 Rename locals to avoid shadowing.
22584 * minibuf.c (choose_minibuf_frame_1): Now static.
22585 (Ftry_completion, Fall_completions): Rename or remove locals
22586 to avoid shadowing.
22588 * marker.c (bytepos_to_charpos): Remove; unused.
22590 * lisp.h (verify_bytepos, count_markers): New decls,
22591 so that gcc does not warn that these functions aren't declared.
22593 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22594 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22595 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22596 (copy_text): Remove unused local var.
22598 * filelock.c (within_one_second): Now static.
22599 (lock_file_1): Rename local to avoid shadowing.
22601 * buffer.c (fix_overlays_before): Mark locals as initialized.
22602 (fix_start_end_in_overlays): Likewise. This function should be
22603 simplified by using pointers-to-pointers, but that's a different
22605 (switch_to_buffer_1): Now static.
22606 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22607 (report_overlay_modification): Rename locals to avoid shadowing.
22609 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22610 Fix pointer signedness issue.
22611 (sys_subshell): Mark local as volatile if checking for lint,
22612 to suppress a gcc -Wclobbered warning that does not seem to be right.
22613 (MAXPATHLEN): Define only if needed.
22615 * process.c (serial_open, serial_configure): Move decls from here ...
22616 * systty.h: ... to here, so that they can be checked.
22618 * fns.c (get_random, seed_random): Move extern decls from here ...
22619 * lisp.h: ... to here, so that they can be checked.
22621 * sysdep.c (reset_io): Now static.
22622 (wait_for_termination_signal): Remove; unused.
22624 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22625 (copy_keymap_item, append_key, push_text_char_description):
