99 (search_regs_saved, Fregexp_quote):
100 Use bool for boolean.
101 * region-cache.c (region_cache_forward, region_cache_backward):

142 to match other functions accepting character and byte positions.
144 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

224 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
225 * sysdep.c (list_system_processes)
226 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
227 Make it a stub in this case; otherwise the build might fail,
228 and this code hasn't been tested on such hosts anyway.
229 Problem reported by Nelson H. F. Beebe in
230 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
231 and analyzed by Jérémie Courrèges-Anglas in
232 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
234 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
236 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.

242 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
244 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
245 * filelock.c: Include <c-ctype.h>.
246 (MAX_LFINFO): New top-level constant.
247 (lock_info_type): Remove members pid, boot_time. Add members at,
248 dot, colon. Change user member to be the entire buffer, not a
249 pointer. This allows us to handle the case where a foreign
250 pid or boot time exceeds the local range. All uses changed.
251 (LINKS_MIGHT_NOT_WORK): New constant.
252 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
253 (defined_WINDOWSNT): Remove.
254 (MAKE_LOCK_NAME, file_in_lock_file_name):
255 Always use .#FILE (not .#-FILE) for the file lock,
256 even if it is a regular file.
257 (rename_lock_file): New function.
258 (create_lock_file): Use it.
259 (create_lock_file, read_lock_data):
260 Prefer a symbolic link for the lock file, falling back on a
261 regular file if symlinks don't work. Do not try to create
262 symlinks on MS-Windows, due to security hassles. Stick with
263 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
264 link, rename, unlink, mkstemp) when creating locks, as a GNUish
265 host may be using a Windowsish file system, and cannot use
266 MS-Windows-only system calls. Fall back on mktemp if mkstemp
267 doesn't work. Don't fail merely because of a symlink-contents
268 length limit in the current file system; fall back on regular
269 files. Increase the symlink contents length limit to 8 KiB, this
270 should be big enough for any real use and doesn't crunch the
272 (create_lock_file, lock_file_1, read_lock_data):
273 Simplify allocation of lock file buffers now that they fit in 8 KiB.
274 (lock_file_1): Return error number, not bool. All callers changed.
275 (ELOOP): New macro, if not already defined.
276 (read_lock_data): Return size of lock file contents, not Lisp object.
277 All callers changed. Handle a race condition if some other process
278 replaces a regular-file lock with a symlink lock or vice versa,
279 while we're trying to read the lock.
280 (current_lock_owner): Parse contents more carefully, to help avoid
281 confusing a regular-file lock with some other application's use
282 of the file. Check for lock file contents being too long, or
283 not parsing correctly.
284 (current_lock_owner, lock_file):
285 Allow foreign pid and boot times that exceed the local range.
286 (current_lock_owner, lock_if_free, lock_file):
287 Simplify allocation of lock file contents.
288 * w32.c (sys_rename_replace): New function, containing most of
289 the contents of the old sys_rename.
290 (sys_rename): Use it.
291 (fchmod): New dummy function.
292 * w32.h (sys_rename_replace, fchmod): New decls.
294 2013-03-05 Eli Zaretskii <eliz@gnu.org>
296 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
297 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
298 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
299 <dmantipov@yandex.ru>.
301 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
303 * composite.c (get_composition_id, fill_gstring_header):
304 Use make_uninit_vector where appropriate.
305 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
306 * xselect.c (clean_local_selection_data): Likewise.
308 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
310 Fix misuse of ImageMagick that caused core dump (Bug#13846).
311 * image.c (imagemagick_load_image): Calculate height and width
312 after flattening the image, not before.
314 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
316 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
317 * ftfont.c (ftfont_shape_by_flt): Likewise.
318 * w32uniscribe.c (uniscribe_shape): Likewise.
320 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
322 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
323 The old approach, which fell back on DIR/.#FILE.0 through
324 DIR/.#FILE.9, had race conditions that could not be easily fixed.
325 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
326 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
327 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
328 because the locking mechanism was never reliable in that case).
329 This patch fixes this and other bugs discovered by a code
330 inspection that was prompted by
331 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
332 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
333 to avoid interoperability problems between the MS-Windows and
334 non-MS-Windows implementations. MS-Windows and non-MS-Windows
335 instances of Emacs now ignore each others' locks.
336 * filelock.c (defined_WINDOWSNT): New constant.
337 (MAKE_LOCK_NAME, fill_in_lock_file_name):
338 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
339 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
340 regular files on MS-Windows hosts.
341 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
342 Use SAFE_ALLOCA to avoid problems with long file names.
343 (MAX_LFINFO): Now a local constant, not a global macro.
344 (IS_LOCK_FILE): Remove.
345 (lock_file_1): Don't inspect errno if symlink call succeeds;
347 (lock_file): Document that this function can return if lock
349 (lock_file): Don't access freed storage.
351 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

355 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
357 * textprop.c: Use bool for booleans.
358 (validate_interval_range, Fadd_text_properties)
359 (Fremove_text_properties): Prefer bool to int when either works.
361 2013-03-02 Eli Zaretskii <eliz@gnu.org>
363 * textprop.c (Fadd_text_properties, Fremove_text_properties):
364 If the interval tree changes as a side effect of calling
365 modify_region, re-do processing starting from the call to
366 validate_interval_range. (Bug#13743)
368 2013-02-28 Eli Zaretskii <eliz@gnu.org>
370 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
373 2013-02-27 Eli Zaretskii <eliz@gnu.org>
375 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
376 _SH_DENYRW flag, instead of emacs_open, to deny any other process
377 access to the lock file until it is written and closed.
380 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
382 * callint.c (Qcall_interactively):
383 * macros.c (Qexecute_kbd_macro):

390 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
392 Minor textprop integer cleanup.
393 * intervals.h, textprop.c (add_text_properties_from_list):
394 Return void, not int, since nobody uses the return value.
395 * textprop.c (validate_plist, add_properties, remove_properties)
396 (Fadd_text_properties):
397 Don't assume list length fits in int.
398 (interval_has_all_properties, interval_has_some_properties)
399 (interval_has_some_properties_list, add_properties, remove_properties)
400 (Fadd_text_properties, Fremove_text_properties)
401 (Fremove_list_of_text_properties, text_property_stickiness):
402 Use bool for booleans.
403 (Fadd_text_properties, Fremove_text_properties):
404 (Fremove_list_of_text_properties):
405 Reindent do-while as per GNU style.

409 Implement CLASH_DETECTION for MS-Windows.
411 * filelock.c [WINDOWSNT]: Include w32.h.

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

457 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
458 (buildobj.h): Use it.
459 ($(ALLOBJS)): Depend on globals.h.
460 (temacs$(EXEEXT)): Use $(ALLOBJS).

479 (check_memory_limits): Simplify and remove casts.
480 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
481 (memory_warnings): Use data_start instead of start_of_data.
483 2013-02-24 Andreas Schwab <schwab@linux-m68k.org>
485 * xdisp.c (set_message): Only check for debug-on-message if STRING
486 is a string. (Bug#13797)
488 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>

491 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
492 2012-07-10 patch to this file. Reported by Eli Zaretskii in
493 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
494 and diagnosed by Andreas Schwab in
495 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
497 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
499 Assume C89 or better.
500 * ralloc.c (SIZE, POINTER, NIL):
501 * vm-limit.c (POINTER):
502 Remove, replacing all uses with C89 equivalents. These old
503 symbols were present only for porting to pre-C89 platforms.
505 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
507 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
508 This avoids warning messages reported as part of Bug#13546.
510 2013-02-21 Ken Brown <kbrown@cornell.edu>
512 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
514 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
516 * sheap.c (report_sheap_usage): Prefer message1_nolog.
518 * keyboard.c (Qcommand_execute): New var.
519 (command_loop_1, read_char): Use it.
520 (Fcommand_execute): Remove, replace by an Elisp implementation.
521 (syms_of_keyboard): Adjust accordingly.
523 2013-02-19 Daniel Colascione <dancol@dancol.org>
525 * sheap.c (report_sheap_usage): Use message, not message1, so
526 that we don't try to create a buffer while we're in the middle
527 of dumping Emacs. Explain why.
529 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
531 * search.c (find_newline): Return byte position in bytepos.

541 (get_visually_first_element, move_it_vertically_backward):
542 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
544 2013-02-19 Eli Zaretskii <eliz@gnu.org>
546 * w32proc.c (new_child): Avoid leaking handles if the subprocess
547 resources were not orderly released.
549 2013-02-17 Eli Zaretskii <eliz@gnu.org>
551 * xdisp.c (x_draw_vertical_border): For a window that is neither
552 the leftmost nor the rightmost, redraw both the left and the right
553 vertical borders. (Bug#13723)
555 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

573 2013-02-16 Eli Zaretskii <eliz@gnu.org>
575 * w32.c (sys_chown): Remove unused function.
577 * w32term.c <input_signal_count>: Declare 'volatile'
578 unconditionally. (Bug#9066)
580 * w32.c (set_errno): Reset h_errno and don't set it to any other
581 value. Set errno instead.
582 (check_errno): Reset h_errno.

594 2013-02-15 Eli Zaretskii <eliz@gnu.org>
596 * keyboard.c (read_char): Fix calculation of auto-save time out
597 when auto-save-timeout is less than 4. (Bug#13720)
599 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

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

626 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
628 Fix AIX port (Bug#13650).
629 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
630 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
631 was #undeffed earlier, so it cannot be used as a macro here.
632 Use the constant and not the macro.
634 2013-02-15 Eli Zaretskii <eliz@gnu.org>
636 * w32proc.c (new_child): If no vacant slots are found in
637 child_procs[], make another pass looking for slots whose process
638 has exited or died. (Bug#13546)

641 MAXDESC, set errno to EMFILE.
642 (_sys_read_ahead): Update cp->status when failing to read serial
643 communications input, so that the status doesn't stay at
644 STATUS_READ_IN_PROGRESS. (Bug#13546)
646 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
648 * gtkutil.c (tb_size_cb): New function.
649 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

653 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
656 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
658 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
660 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
662 * font.c (font_range): Add pos_byte argument. Adjust comment
664 * font.h (font_range): Adjust prototype.
665 * composite.c (autocmp_chars): Pass byte position to font_range.

668 2013-02-13 Glenn Morris <rgm@gnu.org>
670 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
672 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
674 Improve AIX port some more (Bug#13650).
675 With this, it should be as good as it was in 23.3, though it's
676 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
677 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
678 * unexaix.c (start_of_text): Remove.
679 (_data, _text): Declare as char[], not int, as AIX manual suggests.
680 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
681 (orig_load_scnptr, orig_data_scnptr):
682 Now off_t, not long, since they are file offsets.
683 (make_hdr): Use _data, not start_of_data ().
684 This is the key part of the fix.
685 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
686 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
688 * pre-crt0.c (data_start): Initialize to 1.
689 This ports to compilers that optimize the external declaration
690 'int x = 0;' as if it were 'int x;' to shrink the executable.
692 Improve AIX port (Bug#13650).
693 This doesn't fix the bug, but it makes progress: Emacs builds now.
694 * unexaix.c: Include inttypes.h, stdarg.h.
695 (report_error, report_error_1): Mark as _Noreturn.
696 (report_error): Don't report the wrong errno.
697 (report_error_1): Now varargs. All callers changed.
698 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
699 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
700 (write_ptr): Use %p to print address rather than %lx and a cast
701 to unsigned long. Grow buffer a bit, to be safer.
703 2013-02-13 Eli Zaretskii <eliz@gnu.org>
705 * bidi.c (bidi_resolve_neutral): After finding the next
706 non-neutral character, accept NEUTRAL_ON type as well, because
707 directional control characters, such as LRE and RLE, have their
708 type converted to that by bidi_resolve_weak. This avoids aborts
709 when LRE/RLE follows a run of neutrals.
710 (bidi_move_to_visually_next): Assert that return value of
711 bidi_peek_at_next_level is non-negative. Negative values will
714 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
716 Minor getenv-related fixes.
717 * callproc.c (Fcall_process_region) [!DOS_NT]:
718 Avoid unnecessary duplicate call to getenv.
719 * callproc.c (init_callproc):
720 * dispnew.c (init_display):
721 * sysdep.c (sys_subshell):
722 Omit unnecessary cast of getenv or egetenv.
724 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
726 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
729 2013-02-12 Eli Zaretskii <eliz@gnu.org>
731 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
733 (display_line): Set w->region_showing to the value of
734 it->region_beg_charpos, not to -1. This fixes redisplay
735 optimization when cursor is moved up after M->. (Bug#13623)
737 (try_scrolling): Scroll text up more if point is too close to ZV
738 and inside the scroll margin. This makes sure point is moved
739 outside the scroll margin in these cases.
741 * window.h (struct window): region_showing can no longer be
744 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
746 Tune by using memchr and memrchr.
747 * doc.c (Fsnarf_documentation):
748 * fileio.c (Fsubstitute_in_file_name):
749 * search.c (find_newline, scan_newline):
750 * xdisp.c (pos_visible_p, display_count_lines):
751 Use memchr and memrchr rather than scanning byte-by-byte.
752 * search.c (find_newline): Rename from scan_buffer.
753 Omit first arg TARGET, as it's always '\n'. All callers changed.
755 Clean up read_key_sequence a tiny bit more.
756 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
757 (read_key_sequence): Remove unused locals.
759 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
761 Clean up read_key_sequence a bit; reread active keymaps after first event.
762 * keyboard.c (read_char, read_char_x_menu_prompt)
763 (read_char_minibuf_menu_prompt):
764 Replace nmaps+maps with a single `map' arg.
765 (follow_key): Operate on a single map.
766 (active_maps): New function.
767 (test_undefined): Also return true for nil bindings.
768 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
769 a single (composed) keymap. Remember `first_event' to choose the right
770 set of active keymaps. Recompute the set of keymaps after receiving
771 the first event. Remove GOBBLE_FIRST_EVENT.
772 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
773 * keyboard.h (read_char): Update declaration.
774 * lread.c (read_filtered_event): Adjust call to read_char.
776 2013-02-11 Eli Zaretskii <eliz@gnu.org>
778 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
779 Don't use the limitation on backwards movement when lines are truncated
780 in the window. (Bug#13675)
782 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
784 * marker.c (set_marker_internal): If desired position is passed
785 as a marker, avoid call to buf_charpos_to_bytepos.
786 * window.c (Fset_window_point): Omit redundant type checking.
787 (Fset_window_start): Likewise. Format comment.
788 (window_scroll_pixel_based): Use set_marker_restricted_both
789 with character and byte positions obtained from an iterator.
790 (Fset_window_configuration): Use set_marker_restricted_both.
791 * xdisp.c (message_dolog): Likewise.
793 2013-02-10 Eli Zaretskii <eliz@gnu.org>
795 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
796 When text lines are longer than window's screen lines, don't move back
797 too far. This speeds up some redisplay operations. (Bug#13675)
799 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
801 * syntax.c (scan_sexps_forward): Fix byte position calculation
802 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
804 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
806 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
809 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
811 Minor hashing refactoring.
812 * fns.c (SXHASH_REDUCE): Move to lisp.h.
813 (sxhash_float): Return EMACS_UINT, for consistency with the other
815 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
816 non-static inline function and therefore can't use static vars.
817 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
818 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
819 with the other hash functions.
821 2013-02-09 Eli Zaretskii <eliz@gnu.org>
823 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
824 XXXXXX part of the temporary file pattern is not downcased even
825 when w32-downcase-file-names is non-nil. (Bug#13661)
827 * xdisp.c (decode_mode_spec): Remove handling of %t.
829 * msdos.c (careadlinkatcwd): Remove.
831 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
833 * lread.c (skip_dyn_bytes): New function (bug#12598).

839 * search.c (scan_buffer): Calculate end byte position just once.
840 (scan_newline): Do not recalculate start_byte.
841 (search_command): Use eassert.
842 * syntax.c (struct lisp_parse_state): New member location_byte.
843 (scan_sexps_forward): Record from_byte and avoid redundant

862 * window.c (Fcurrent_window_configuration):
863 * xfaces.c (Fx_family_fonts):
864 * xselect.c (selection_data_to_lisp_data): Use it.
866 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
868 * coding.c (Fdefine_coding_system_internal): Use AREF where
869 argument is known to be a vector.
870 * fns.c (Flocale_info): Likewise for ASET.
871 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.

881 updateCollectionBehaviour.
883 * nsterm.m (NEW_STYLE_FS): Remove.
884 (ns_last_use_native_fullscreen): New variable.
885 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
886 (x_set_window_size): Do not take title bar and tool bar into account
887 if isFullscreen returns YES.
888 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
889 (check_native_fs): New function.
890 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
891 (ns_term_init): Remove NEW_STYLE_FS.

893 and tool bar if isFullscreen returns NO.
894 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
895 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
897 (window:willUseFullScreenPresentationOptions:): New method.
898 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
899 Hide toolbar if not enabled (Bug#13444).
900 (windowDidExitFullScreen:): Call updateCollectionBehaviour.

902 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
903 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
904 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
905 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
906 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
907 (syms_of_nsterm): Add ns-use-native-fullscreen.
909 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
911 * fileio.c (Qchoose_write_coding_system): Now static.
913 2013-02-04 Eli Zaretskii <eliz@gnu.org>
915 * xdisp.c (window_buffer_changed): region_showing can be negative,
916 which still means region is being displayed.
917 (redisplay_internal): Resurrect code that forced redisplay of the
918 whole window when showing region and the mark has changed.
919 Record the new mark position to allow redisplay optimizations.
920 (display_line): If it->region_beg_charpos is non-zero, set the
921 window's region_showing member to -1. (Bug#13623) (Bug#13626)
923 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
924 not bitfield of 1 bit.
926 2013-02-03 Daniel Colascione <dancol@dancol.org>
928 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
929 daemon mode works on cygw32 when Emacs is installed and not just
932 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
934 Avoid file time stamp bug on MS-Windows (Bug#13149).
935 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
936 as FAT32 doesn't update time stamps when truncating them.
937 Also, check that a file time stamp is not a multiple of 100 ns;
938 this should catch all instances of the problem on MS-Windows,
939 as its native file system resolution is 100 ns or worse, and
940 checking for a non-multiple of 100 ns should impose only a small
941 overhead on systems with ns resolution.
943 2013-02-02 Eli Zaretskii <eliz@gnu.org>
945 Avoid encoding file names on MS-Windows when they need to be run
946 through dostounix_filename.
947 * w32.c (normalize_filename): Accept an additional argument
948 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
949 downcase it even if w32-downcase-file-names is non-nil.
950 (dostounix_filename): Accept an additional argument MULTIBYTE and
951 pass it to normalize_filename.
952 (emacs_root_dir): Adjust.
954 * msdos.h (dostounix_filename): Adjust prototype.
956 * w32.h (dostounix_filename): Adjust prototype.
958 * msdos.c (dostounix_filename): Accept an additional argument and
960 (init_environment): Adjust callers of dostounix_filename.
962 * fileio.c (Ffile_name_directory, file_name_as_directory)
963 (directory_file_name, Fexpand_file_name)
964 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
966 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
968 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
969 variables, as egetenv is case-insensitive for DOS_NT.
971 * dired.c (file_name_completion): Don't call Fdirectory_file_name
972 with an encoded file name.
974 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
975 Adjust calls to dostounix_filename.
977 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
979 * unexw32.c (unexec): Adjust call to dostounix_filename.

983 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
986 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
989 * callproc.c (Fcall_process): Make sure program name in PATH and
990 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
991 is passed to exec/spawnve, which fails unless the file-name
994 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
995 even if w32-quote-process-args is nil.
997 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
999 Fix timestamp bug when write-region appends nothing (Bug#13149).
1000 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1001 the file's time stamp doesn't change if Emacs happens to write nothing
1002 to the file, and on a buggy file system this could cause Emacs to
1003 incorrectly infer that the file system doesn't have the bug.
1004 Avoid this problem by inhibiting the inference in this case.
1006 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1008 * window.h (struct window): Convert base_line_number, base_line_pos
1009 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1010 Convert region_showing member from Lisp_Object to bitfield.
1011 Remove sequence_number member. Adjust comments.
1012 * window.c (sequence_number): Remove.
1013 (make_window): Initialize column_number_displayed.
1014 * print.c (print_object): Follow the printed representation of
1015 frames and print window pointer to distinguish between windows.
1016 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1017 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1018 (wset_column_number_displayed, wset_region_showing): Remove.
1019 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1020 (try_scrolling, try_cursor_movement, redisplay_window)
1021 (try_window_reusing_current_matrix, try_window_id, display_line)
1022 (display_mode_lines, decode_mode_spec): Adjust users.
1023 * .gdbinit (pwinx): Do not print sequence_number.
1025 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1027 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1028 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1029 * dired.c: Include <fcntl.h>.
1030 (open_directory): New function, which uses open and fdopendir
1031 rather than opendir. DOS_NT platforms still use opendir, though.
1032 (directory_files_internal, file_name_completion): Use it.
1033 (file_attributes): New function, with most of the old Ffile_attributes.
1034 (directory_files_internal, Ffile_attributes): Use it.
1035 (file_attributes, file_name_completion_stat): First arg is now fd,
1036 not dir name. All uses changed. Use fstatat rather than lstat +
1038 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1039 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1040 (emacs_readlinkat): New function, with much of the old
1041 Ffile_symlink_p, but with an fd argument for speed.
1042 It uses readlinkat rather than careadlinkatcwd, so that it
1043 need not assume the working directory.
1044 (Ffile_symlink_p): Use it.
1045 * filelock.c (current_lock_owner): Use emacs_readlinkat
1046 rather than emacs_readlink.
1047 * lisp.h (emacs_readlinkat): New decl.
1048 (READLINK_BUFSIZE, emacs_readlink): Remove.
1049 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1050 (emacs_norealloc_allocator, emacs_readlink): Remove.
1051 This stuff is moved to fileio.c.
1052 * w32.c (fstatat, readlinkat): New functions.
1053 (careadlinkat): Don't check that fd == AT_FDCWD.
1054 (careadlinkatcwd): Remove; no longer needed.

1059 (Fwrite_region): Update for new choose_write_coding_system args.
1060 Move the last piece of choose_write_coding_system here. (Bug#13522)
1061 (syms_of_fileio): Add choose-write-coding-system.
1063 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1065 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1066 (sys_close): Zero out the flags for the file descriptor before
1067 closing it. (Bug#13546)
1069 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1070 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1071 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1074 * w32.c (w32_get_long_filename, init_environment, readlink):
1075 Support file names encoded in DBCS codepages.
1076 (readlink): Use the current file-name-coding-system, not the ANSI
1077 codepage, to decode and handle targets of symlinks.
1079 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1081 * w32.c (opendir): Now accepts a 'const char *'.
1083 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1085 Remove obsolete redisplay code. See the discussion at
1086 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1087 * dispnew.c (preemption_period, preemption_next_check): Remove.
1088 (Vredisplay_preemption_period): Likewise.
1089 (update_frame, update_single_window, update_window, update_frame_1):
1090 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1091 used, following the 2012-06-22 change.
1093 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1095 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1097 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1099 * font.c (num_fonts): Remove the leftover from old
1100 debugging code. Adjust comment style here and there.
1101 * insdel.c (insert_1): Remove.
1102 * lisp.h (insert_1): Remove prototype.
1103 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1105 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1107 * w32.c (max_filename_mbslen): New function.
1108 (normalize_filename, readdir): Use it to detect locales where ANSI
1109 encoding of file names uses a double-byte character set (DBCS).
1110 If a DBCS encoding is used, advance by characters using
1111 CharNextExA, instead of incrementing a 'char *' pointer.
1112 Use _mbslwr instead of _strlwr. (Bug#13515)
1114 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1115 request of memory reservation to 1.7GB. (Bug#13065)
1117 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1119 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1120 at check_extra_latin label. (Bug#13505)
1122 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1124 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1125 Avoid redundant calls to strlen.
1127 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1129 Drop async_visible and async_iconified fields of struct frame.
1130 This is possible because async input is gone; for details, see
1131 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1132 * frame.h (struct frame): Remove async_visible and async_iconified
1133 members, convert garbaged to unsigned bitfield. Adjust comments.
1134 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1135 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1136 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1137 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1138 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1140 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1141 properly. Likewise for obscured.
1143 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1146 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1148 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1150 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1151 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1153 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1155 * xdisp.c (message2, message2_nolog): Remove functions.
1156 (message3, message3_nolog): Extract nbytes and multibyteness directly
1157 from the string. Change all callers.
1158 (message3_nolog): Don't set message_enable_multibyte since set_message
1159 will reset it anyway.
1160 (message1, message1_nolog): Use message3.
1161 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1162 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1163 (set_message): Drop all but the second arg, which has to be a string.
1164 (set_message_1): Simplify now that we know that a1 is NULL and the
1165 second arg is a string.
1166 * frame.h (struct frame): Remove `message_buf' field.
1167 Use glyphs_initialized_p instead.
1168 (FRAME_MESSAGE_BUF): Remove macro.
1169 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1170 * lisp.h (message2, message2_nolog): Remove declarations.
1171 (message3, message3_nolog): Update declarations.
1172 * keyboard.c (read_char_minibuf_menu_text)
1173 (read_char_minibuf_menu_width): Remove vars.
1174 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1175 to correctly handle multibyte strings.
1176 * frame.c (delete_frame): Don't free message_buf any more.
1177 * editfns.c (message_text, message_length): Remove vars.
1178 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1179 * fileio.c (auto_save_error): Use message3 instead of message2.
1180 * dispnew.c (adjust_frame_message_buffer): Remove function.
1182 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1184 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1185 real estate used for the tool bar and the menu bar.
1187 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1189 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1190 hidden buffer is prepared to modification (Bug#13164).
1192 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1194 * window.h (struct window): Change window_end_valid member from
1195 Lisp_Object to a bitfield. Adjust comments.
1196 (wset_window_end_valid): Remove.
1197 * window.c (adjust_window_count): Clear window_end_valid.
1198 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1199 (Fwindow_line_height, set_window_buffer, Frecenter)
1200 (Fsplit_window_internal, Fdelete_other_windows_internal)
1201 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1202 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1203 * xdisp.c (check_window_end, reconsider_clip_changes)
1204 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1205 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1206 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1208 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1210 * xdisp.c (mark_window_display_accurate): Simplify the loop
1211 assuming that the only one of vchild, hchild or buffer window
1212 slots is non-nil. Call mark_window_display_accurate_1 for
1213 the leaf windows only.
1214 (mark_window_display_accurate_1): Always assume leaf window.
1217 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1219 * emacs.c (Qkill_emacs_hook): Now static.
1221 * fileio.c (Finsert_file_contents): Simplify.
1222 Remove unnecessary assignments and tests.
1224 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1226 * w32.c (acl_set_file): Don't test for errors unless
1227 set_file_security returns FALSE. Avoids spurious errors when
1230 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1232 * fileio.c (Finsert_file_contents): Revert code introduced at
1233 2013-01-18 in favor of the simpler and generally better fix.
1234 Save stack space by removing 'buffer' and reusing 'read_buf'
1237 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1239 * lisp.h (eabs): Define unconditionally (Bug#13419).
1240 The old "#if !defined (eabs)" was an unnecessary revenant of back
1241 when this macro was called "abs". Document 'eabs' better.
1243 2013-01-19 Glenn Morris <rgm@gnu.org>
1245 * fns.c (Frandom): Doc fix.
1247 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1249 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1250 segfault when there are lots of overlays.
1252 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1253 when there are lots of overlays.
1254 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1255 for the details and a way to reproduce.
1257 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1259 * fileio.c: Use O_APPEND to append.
1260 This corresponds better to the natural interpretation of "append",
1261 and avoids the need to open the output file twice, or to invoke
1262 lseek when APPEND is neither nil nor a number.
1263 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1264 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1265 file possibly twice, and lseeking to its end; this avoids the
1266 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1267 at the same time: the combination is never needed and apparently
1268 it doesn't work with DOS_NT.
1270 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1271 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1273 Allow floating-point file offsets.
1274 Problem reported by Vitalie Spinu in
1275 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1276 * fileio.c (emacs_lseek): Remove.
1277 (file_offset): New function.
1278 (Finsert_file_contents, Fwrite_region): Use it.
1280 2013-01-19 Chong Yidong <cyd@gnu.org>
1282 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1283 aborting on Fsignal (Bug#13289).
1285 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1287 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1288 set_file_security as failure due to insufficient privileges.
1289 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1290 (fstat): Return owner and group like 'stat' and 'lstat' do.
1292 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1294 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1295 The bug was observed on Ubuntu operating inside a virtual machine,
1296 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1297 The workaround introduces a race condition on non-buggy hosts,
1298 but it's an unlikely race and anyway there's a nearly identical
1299 nearby race that can't be fixed.
1300 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1302 (Fwrite_region): Test for file system time stamp bug.
1303 (init_fileio): New function.
1304 * lisp.h (init_fileio): Declare it.
1305 * emacs.c (main): Call it.
1307 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1308 and make it more consistent with other stat-failure diagnostics.
1310 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1312 Fix crash when inserting data from non-regular files.
1313 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1314 for the error description produced by valgrind.
1315 * fileio.c (read_non_regular): Rename to read_contents.
1316 Free Lisp_Save_Value object used to pass parameters.
1317 (read_non_regular_quit): Rename to read_contents_quit.
1318 (Finsert_file_contents): Redesign internal file reading loop to adjust
1319 gap and end positions after each read and so help make_gap to work
1320 properly. Do not signal an I/O error too early and so do not leave
1321 not yet decoded characters in a buffer, which was the reason of
1322 redisplay crash. Use list2 to build return value. Adjust comments.
1324 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1326 Close a race when statting and reading files (Bug#13149).
1327 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1328 This avoids a race if the file is renamed between stat and open.
1329 This race is not the problem originally noted in Bug#13149;
1330 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1332 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1334 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
1335 objects, related functions and macros.
1336 (make_save_value): Adjust prototype.
1337 (make_save_pointer): New prototype.
1338 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
1339 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1340 * alloc.c (format_save_value): Rename to make_save_value.
1341 (make_save_pointer): New function.
1342 (record_xmalloc): Use make_save_pointer.
1343 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1344 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1345 Change users of make_save_value to make_save_pointer.
1346 Likewise for format_save_value and make_save_value.
1348 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1350 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
1351 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
1352 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
1355 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
1357 * alloc.c (free_save_value): Now static.
1359 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1361 * keymap.c (map_keymap_internal): Use format_save_value.
1362 (map_keymap_char_table_item): Adjust accordingly.
1363 * fileio.c (non_regular_fd, non_regular_inserted)
1364 (non_regular_nbytes): Remove.
1365 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1366 Use format_save_value to pass parameters to read_non_regular.
1367 (read_non_regular): Use XSAVE_ macros to extract parameters.
1369 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1371 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1373 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1375 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1376 extraction from any Lisp_Save_Value slot. Add type checking.
1377 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1378 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1379 * xselect.c: All users changed.
1381 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1383 Some convenient bits to deal with Lisp_Save_Values.
1384 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
1385 (allocate_misc): Remove prototype.
1386 (format_save_value): New prototype.
1387 * alloc.c (allocate_misc): Revert back to static.
1388 (format_save_value): New function to build Lisp_Save_Value
1389 object with the specified internal structure.
1390 (make_save_value): Reimplement using format_save_value.
1391 * editfns.c (save_excursion_save): Use format_save_value.
1392 (save_excursion_restore): Use XSAVE_OBJECT.
1394 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1396 Avoid needless casts with XSAVE_POINTER.
1397 * alloc.c (mark_object) [GC_MARK_STACK]:
1398 * dired.c (directory_files_internal_unwind):
1399 * fileio.c (do_auto_save_unwind):
1400 * gtkutil.c (pop_down_dialog):
1401 * keymap.c (map_keymap_char_table_item):

1429 * editfns.c (save_excursion_save): Pack everything within
1430 Lisp_Save_Value and so avoid xmalloc.
1431 (save_excursion_restore): Adjust to match new layout. Use free_misc
1432 because we do not allocate extra memory any more. Add eassert.
1433 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1434 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1435 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
1436 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

1446 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1448 Fix SIGDANGER handlers, for AIX (Bug#13408).
1449 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1450 Move handlers here from emacs.c; they were out of place.
1452 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1454 * xterm.c (syms_of_xterm): Adjust documentation for

1502 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1504 Avoid unnecessary byte position calculation for the gap movement.
1505 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1516 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1518 * term.c (init_tty): Use them instead of rolling our own code.
1519 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1520 switches from 'signal' to 'pthread_sigmask', which is safer in
1521 multithreaded applications.
1522 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1523 which has already arranged for that.
1524 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1525 This is the main part of the bug fix.

1537 predicate, which is how it's really used now. Adjust comment.
1538 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1539 * buffer.c (buffer_slot_type_mismatch): Remove.
1540 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1541 predicate. Adjust comment.

1544 left-margin-width, right-margin-width, left-fringe-width,
1545 right-fringe-width, scroll-bar-width and buffer-display-count.
1546 Use Qstringp for default-directory, buffer-file-name,
1547 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1548 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1550 * data.c (store_symval_forwarding): Adjust to call the predicate.

1567 (make_gap_1): New function to adjust the gap of any buffer.
1568 * coding.c (coding_alloc_by_making_gap): Use it.
1569 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1593 trailing dash is properly added.
1595 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1597 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1598 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1599 digits for buffer positions, before misalignment starts.
1600 Display "0" for integer "object" field.
1601 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1602 Display the newline glyph more unambiguously.
1604 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1606 * nsterm.m (ns_draw_underwave):
1607 * w32term.c (w32_draw_underwave):
1608 * xterm.c (x_draw_underwave): Make underwave look more triangular
1609 and also degrade gracefully for small fonts. (Bug#13000)
1611 * nsterm.m (ns_draw_text_decoration):
1612 * w32term.c (x_draw_glyph_string):
1613 * xterm.c (x_draw_glyph_string): Don't use previous underline
1614 thickness and position if previous underline type is underwave.
1616 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1618 * fileio.c (Ffile_acl): Undocument return format.
1620 2013-01-02 Glenn Morris <rgm@gnu.org>

1634 * term.c (tty_ins_del_lines):
1635 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1636 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1638 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1640 * w32.c (unsetenv): Set up the string passed to _putenv
1642 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1643 for the bug this caused.
1645 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1647 * coding.c (Qmac): Now static.
1649 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1651 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1652 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1659 by TOOLBAR_TOP_WIDGET.
1660 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1661 Check toolbar_is_packed.
1662 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1663 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1664 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1666 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1667 (xg_update_menubar): Update title only if
1668 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1669 (xg_update_submenu): Skip tearoff only if
1670 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1671 (xg_initialize): Initialize xg_detached_menus only if
1672 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1674 * xterm.h (struct x_output): Surround handlebox_widget with
1675 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1676 toolbar_in_hbox is bool.
1678 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1680 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1681 (LIBS_GNUSTEP): Define.
1682 (LIBES): Add $(LIBS_GNUSTEP).
1683 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1685 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1687 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1688 continuation glyph on a TTY with an indication of an empty line.
1691 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1693 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1694 file's SELinux context or ACLs successfully set, nil otherwise.
1696 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1698 * w32proc.c (reader_thread): Avoid passing NULL handles to
1699 SetEvent and WaitForSingleObject.
1701 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1703 Port EXTERNALLY_VISIBLE to Clang 3.2.
1704 * conf_post.h (__has_attribute): New macro.
1705 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1707 2012-12-27 Glenn Morris <rgm@gnu.org>
1709 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1710 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1712 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1714 * fileio.c (file_name_as_directory, directory_file_name):
1715 Accept an additional argument MULTIBYTE to indicate whether the input C
1716 came from a multibyte or a unibyte Lisp string; all callers
1717 adjusted. Don't assume the input string is always multibyte.
1719 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1720 don't ENCODE_FILE them, and return a unibyte string if the input
1722 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1723 don't assume the input strings will always be multibyte. If the
1724 input strings are multibyte, decode strings obtained from C
1727 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1729 * lisp.h (toplevel): Add two notices to the comment about
1730 defining a new Lisp data type.

1734 * alloc.c (valid_lisp_object_p): Adjust comment.
1736 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1738 * keyboard.c (record_asynch_buffer_change): Initialize an event
1739 only if it's really needed.
1740 * frame.h (enum output_method): Remove output_mac member since
1741 it's a leftover from the deleted code.
1742 * frame.c (Fframep): Adjust user here ...
1743 * terminal.c (Fterminal_live_p): ... and here.
1744 * coding.c (Qmac): Now here because it's only used to denote
1745 end-of-line encoding type.
1746 (syms_of_coding): DEFSYM it.
1747 * frame.h (Qmac): Remove duplicated declaration.
1749 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1751 * window.c (select_window_1): Now static, since it's used only here.
1753 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1755 * window.c (window_body_cols): Subtract display margins from the
1756 window body width on TTYs as well. See
1757 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1758 for the original report.
1760 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1762 * xdisp.c (redisplay_window): Remove inner local variable
1763 because the outer shadowed one has the same meaning.
1764 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1766 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1767 (xg_create_tool_bar): Adjust users.
1769 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1771 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1772 * buffer.c (Fget_buffer_create): Use it to set compact field of
1773 struct buffer_text to avoid accessing an uninitialized value
1774 when compact_buffer is called for the first time.
1775 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1776 (Fset_buffer_modified_p): Use buffer_window_count to check
1777 whether the buffer is displayed in some window.
1778 * xdisp.c (message_dolog): Likewise.
1780 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1782 * w32.c (acl_set_file): If setting the file security descriptor
1783 fails, and the new DACL is identical to the existing one, silently
1784 return success. This fixes problems for users backing up their
1785 own files without having the necessary privileges for setting
1786 security descriptors.
1788 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1790 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1791 after WaitForSingleObject returns normally. This expedites reader
1792 thread shutdown when delete_child triggers it.
1793 (reap_subprocess): More accurate commentary for why we call
1794 delete_child only when cp->fd is negative.
1796 * w32.c (sys_close): Do not call delete_child on a subprocess
1797 whose handle is not yet closed. Instead, set its file descriptor
1798 to a negative value, so that reap_subprocess will call
1799 delete_child on that subprocess when its SIGCHLD arrives.
1800 This avoids closing handles used for communications between sys_select
1801 and reader_thread, which doesn't give sys_select a chance to
1802 notice that the process exited and invoke the SIGCHLD handler for
1805 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1807 * nsfns.m (Fns_do_applescript): Run event loop until script has
1808 been executed (Bug#12969).
1809 (ns_run_ascript): Chech as_script for nil, set to nil after
1812 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1814 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1816 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1818 * w32term.c (w32fullscreen_hook): New function.
1819 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1821 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1823 * fileio.c (Finsert_file_contents): Doc fix.
1825 * w32proc.c (new_child, delete_child, find_child_pid): For a
1826 subprocess, consider its slot being in use as long as its process
1827 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1828 slot when a new process is started immediately after killing
1829 another one, without waiting enough time for the first process to
1830 be reaped and resources allocated for it be orderly freed.
1832 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1834 2012-12-21 Chong Yidong <cyd@gnu.org>
1836 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1838 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1840 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1842 * w32.c (get_name_and_id): Always pass NULL as the first argument
1843 of lookup_account_sid. Avoids crashes with UNC file names that
1844 refer to DFS domains, not to specific machine names. (Bug#12621)
1845 Remove now unused argument FNAME; all callers changed.
1846 (get_file_owner_and_group): Remove now unused argument FNAME; all
1849 2012-12-21 Chong Yidong <cyd@gnu.org>
1851 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1852 error for invalid chars, don't check for a nil return value.
1854 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1856 Avoid calls to CHAR_TO_BYTE if byte position is known.
1857 * editfns.c (make_buffer_string_both): Use move_gap_both.
1858 (Fbuffer_string): Use make_buffer_string_both.

1861 (buf_bytepos_to_charpos): Likewise.
1862 (charpos_to_bytepos): Remove.
1863 * fileio.c (Finsert_file_contents): Use move_gap_both.
1864 * search.c (Freplace_match): Likewise.
1865 * process.c (process_send_region): Likewise. Use convenient
1866 names for byte positions.
1867 * lisp.h (charpos_to_bytepos): Remove prototype.
1868 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1869 * insdel.c (move_gap): Likewise.

1940 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1942 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1943 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1944 for some of that bug's symptoms can now cause Emacs to abort.
1945 Remove the workaround.
1946 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1947 The bug that caused SIGCHLD to get lost has been fixed, and the

2029 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2030 owner and group information from 'lstat'.

2034 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2035 as that confuses set-auto-coding, so insist on the head-read

2064 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2066 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2067 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2068 Remove unnecessary S_ISLNK test, as (contra the comments) this
2069 function can't copy symlinks. Improve quality of error message
2070 when attempting to copy files that are neither regular files nor

2350 (record_child_status_change, handle_child_signal, deliver_child_signal)
2351 (init_process_emacs, syms_of_process):
2352 Assume SIGCHLD is defined.
2353 (parse_signal): Remove. All uses removed.
2354 (abbr_to_signal): New static function.
2355 (Fsignal_process): Use it to convert signal names to ints.
2356 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2357 kill (getpgrp (), ...).
2358 (emacs_sigaction_init): Assume SIGCHLD is defined.
2359 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2360 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2361 * syssignal.h (EMACS_KILLPG): Remove.
2362 All uses replaced by 'kill' with a negative pid.
2363 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2364 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2366 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2368 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2369 This will cause a production Emacs to dump core instead of
2372 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2374 * frame.c (make_frame): Do not set window's buffer to t.
2375 * window.c (Fsplit_window_internal): Likewise. Previously it was
2376 used to indicate that the window is being set up. Now we use
2377 set_window_buffer for all new windows, so the condition in ...
2378 (Fset_window_buffer): ... is always true and can be removed.
2380 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2382 Convenient macro to check whether the buffer is hidden.
2383 * buffer.h (BUFFER_HIDDEN_P): New macro.
2384 * frame.c (make_frame): Use it. Adjust comment.
2385 * buffer.c (candidate_buffer): New function.
2386 (Fother_buffer, other_buffer_safely): Use it.
2388 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2390 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2391 if the child process is still running. Instead, exit the wait
2392 loop and return zero. (Bug#13086)
2394 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2396 * frame.h (x_char_width, x_char_height): Remove prototypes.
2397 * w32term.h (x_char_width, x_char_height): Likewise.
2398 * xfns.c (x_char_width, x_char_height): Remove.

2407 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2409 Fix a recently-introduced delete-process race condition.
2410 * callproc.c, process.h (record_kill_process):
2411 New function, containing part of the old call_process_kill.
2412 (call_process_kill): Use it.
2413 This does not change call_process_kill's behavior.
2414 * process.c (Fdelete_process): Use record_kill_process to fix a
2415 race condition that could cause Emacs to lose track of a child.
2417 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2419 Avoid code duplication between prev_frame and next_frame.
2420 * frame.c (candidate_frame): New function. Add comment.
2421 (prev_frame, next_frame): Use it. Adjust comment.
2423 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2425 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2426 fails, signal an error instead of continuing with an empty
2428 Encode expanded temp file pattern before passing it to mkstemp or
2431 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2432 Encode the file name before passing it to dostounix_filename, in
2433 case it will downcase it (under w32-downcase-file-names).
2436 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2438 Minor call-process cleanups.
2439 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2440 at the same time as other platforms, to simplify analysis.
2441 No need for fd0_volatile since we have synch_process_fd.
2442 Avoid needless emacs_close; arg is always negative.
2444 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2446 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2449 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2451 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2452 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2453 and mouse_face_hidden members to a bitfields.
2454 * frame.h (struct frame): Remove set-but-not-used space_width member.
2455 (FRAME_SPACE_WIDTH): Remove.
2456 * nsterm.m, w32term.c, xterm.c: Adjust users.
2457 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2458 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2459 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2460 members to a bitfields.
2462 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2464 Don't let call-process be a zombie factory (Bug#12980).
2465 Fixing this bug required some cleanup of the signal-handling code.
2466 As a side effect, this change also fixes a longstanding rare race
2467 condition whereby Emacs could mistakenly kill unrelated processes,
2468 and it fixes a bug where a second C-g does not kill a recalcitrant
2469 synchronous process in GNU/Linux and similar platforms.
2470 The patch should also fix the last vestiges of Bug#9488,
2471 a bug which has mostly been fixed on the trunk by other changes.
2472 * callproc.c, process.h (synch_process_alive, synch_process_death)
2473 (synch_process_termsig, sync_process_retcode):
2474 Remove. All uses removed, to simplify analysis and so that
2475 less consing is done inside critical sections.
2476 * callproc.c (call_process_exited): Remove. All uses replaced
2477 with !synch_process_pid.
2478 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2479 These take the role of what used to be in unwind-protect arg.
2481 (block_child_signal, unblock_child_signal):
2482 New functions, to avoid races that could kill innocent-victim processes.
2483 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2484 (call_process_kill): Record killed processes as deleted, so that
2485 zombies do not clutter up the system. Do this inside a critical
2486 section, to avoid a race that would allow the clutter.
2487 (call_process_cleanup): Fix code so that the second C-g works again
2488 on common platforms such as GNU/Linux.
2489 (Fcall_process): Create the child process in a critical section,
2490 to fix a race condition. If creating an asynchronous process,
2491 record it as deleted so that zombies do not clutter up the system.
2492 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2493 light of these changes. Omit unnecessary call to emacs_close
2494 before failure, as the unwind-protect code does that.
2495 * callproc.c (call_process_cleanup):
2496 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2497 * process.c (record_deleted_pid): New function, containing
2498 code refactored out of Fdelete_process.
2499 (Fdelete_process): Use it.
2500 (process_status_retrieved): Remove. All callers changed to use
2501 child_status_change.
2502 (record_child_status_change): Remove, folding its contents into ...
2503 (handle_child_signal): ... this signal handler. Now, this
2504 function is purely a handler for SIGCHLD, and is not called after
2505 a synchronous waitpid returns; the synchronous code is moved to
2506 wait_for_termination. There is no need to worry about reaping
2507 more than one child now.
2508 * sysdep.c (get_child_status, child_status_changed): New functions.
2509 (wait_for_termination): Now takes int * status and bool
2510 interruptible arguments, too. Do not record child status change;
2511 that's now the caller's responsibility. All callers changed.
2512 Reimplement in terms of get_child_status.
2513 (wait_for_termination_1, interruptible_wait_for_termination):
2514 Remove. All callers changed to use wait_for_termination.
2515 * syswait.h: Include <stdbool.h>, for bool.
2516 (record_child_status_change, interruptible_wait_for_termination):
2518 (record_deleted_pid, child_status_changed): New decls.
2519 (wait_for_termination): Adjust to API changes noted above.
2521 * bytecode.c, lisp.h (Qbytecode): Remove.
2522 No longer needed after 2012-11-20 interactive-p changes.
2524 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2526 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2527 the scroll margin, move point outside the margin. (Bug#13055)
2529 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2531 * gtkutil.c (my_log_handler): New function.
2532 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2534 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2536 * lisp.h (modify_region): Rename to...
2537 (modify_region_1): ...new prototype.
2538 * textprop.c (modify_region): Now static. Adjust users.
2539 * insdel.c (modify_region): Rename to...
2540 (modify_region_1): ...new function to work with current buffer.
2541 Adjust comment and users. Use true and false for booleans.
2543 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2545 * alloc.c (free_save_value): New function.
2546 (safe_alloca_unwind): Use it.
2547 * lisp.h (free_save_value): New prototype.
2548 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2550 (save_excursion_restore): Adjust to match saved data structure.
2551 Use free_save_value to offload some work from GC. Drop obsolete
2554 2012-12-03 Chong Yidong <cyd@gnu.org>
2556 * fileio.c (Vauto_save_list_file_name): Doc fix.
2558 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2560 * w32fns.c: Remove prototype of atof.
2561 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2563 (file_dialog_callback): Make it UINT_PTR.
2565 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2568 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2569 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2572 2012-12-03 Glenn Morris <rgm@gnu.org>
2574 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2576 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2578 Fix xpalloc confusion after memory is exhausted.
2579 * alloc.c (xpalloc): Comment fix.
2580 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2581 and signals an error, do not clear charset_table_size, as
2582 charset_table is still valid.
2583 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2585 Use execve to avoid need to munge environ (Bug#13054).
2586 * callproc.c (Fcall_process):
2587 * process.c (create_process):
2588 Don't save and restore environ; no longer needed.
2589 * callproc.c (child_setup):
2590 Use execve, not execvp, to preserve environ.
2592 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2594 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2596 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2598 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2599 display for sliced images (Bug#10500).
2601 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2603 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2605 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2606 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2608 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2610 * xdisp.c (window_outdated): Remove eassert since it hits
2611 some suspicious corner cases (see Bug#13007 and Bug#13012).
2612 (mode_line_update_needed): New function.
2613 (redisplay_internal, redisplay_window): Use it.
2614 (ensure_selected_frame): New function.
2615 (redisplay_internal, unwind_redisplay): Use it.
2616 (redisplay_internal): Move comment about buffer_shared...
2617 (buffer_shared_and_changed): ...near to its real use.
2619 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2621 * callproc.c (Fcall_process): Don't misreport vfork failure.
2623 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2625 * callproc.c (Fcall_process): Fix vfork portability problems.
2626 Do not assume that fd[0], count, filefd, and save_environ survive
2627 vfork. Fix bug whereby wrong errno value could be reported for
2628 pipe failure. Some minor cleanups, too, as follows. Move buf and
2629 bufsize to the context where they're needed. Change new_argv to
2630 be of type char **, as this is more convenient and avoids casts.
2631 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2632 Now local constants, not macros.
2634 2012-11-18 Kenichi Handa <handa@gnu.org>
2636 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2637 for the variable "f".
2639 2012-11-13 Kenichi Handa <handa@gnu.org>
2641 * font.c (font_unparse_xlfd): Exclude special characters from the
2642 generating XLFD name.
2644 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2646 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2647 * dired.c (stat_uname, stat_gname):
2648 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2650 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2657 * lread.c (readbyte_from_file): Assume EINTR is defined.
2658 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2659 Assume EIO and EAGAIN are defined.
2660 * unexcoff.c (write_segment): Assume EFAULT is defined.
2662 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2664 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2667 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2668 highlighting on the frame was cleared. Prevents assertion
2669 violations when repeatedly clicking on the "Top" link of the
2670 "bread-crumbs" in Info buffers.
2672 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2674 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2676 2012-11-24 Ken Brown <kbrown@cornell.edu>
2678 * keyboard.c (HAVE_MOUSE):
2679 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2680 were always defined.
2682 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2684 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2685 between bpos_covered and bpos_max. This fixes cursor display when
2686 several display strings follow each other.
2688 * .gdbinit (pgx): If the glyph's object is a string, display the
2689 pointer to string data, rather than the value of the string object
2690 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2692 * indent.c (Fvertical_motion): If the starting position is covered
2693 by a display string, return to one position before that, to avoid
2694 overshooting it inside move_it_to. (Bug#12930)
2696 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2698 * frame.h (struct frame): Remove display_preempted member

2701 * w32menu.c (pending_menu_activation): Remove since not
2703 (set_frame_menubar): Adjust user.
2704 * w32term.h (struct x_output): Drop outdated #if 0 code.
2705 (struct w32_output): Use bitfields for explicit_parent,
2706 asked_for_visible and menubar_active members.
2707 Drop unused pending_menu_activation member.
2708 * xterm.h (struct x_output): Drop outdated #if 0 code.
2709 Use bitfields for explicit_parent, asked_for_visible,
2710 has_been_visible and net_wm_state_hidden_seen members.
2712 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2714 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2715 of a literal "/". (Bug#12955)
2716 (gl-stamp): Invoke fc.exe directly, not through cmd.
2718 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2720 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2721 * dired.c: Assume HAVE_DIRENT_H.
2722 (NAMLEN): Remove, replacing with ...
2723 (dirent_namelen): New function. All uses changed. Use the GNU macro
2724 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2725 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2726 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2727 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2729 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2730 * ndir.h: Rename to ../nt/inc/dirent.h.
2731 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2732 Do not include <dirent.h>; no longer needed.
2733 * w32.c: Include <dirent.h> rather than "ndir.h".
2735 2012-11-23 Chong Yidong <cyd@gnu.org>
2737 * xftfont.c (xftfont_open): Remove duplicate assignment.
2739 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2741 * alloc.c (Fgarbage_collect): Unblock input after clearing
2742 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2743 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2744 * msdos.c (IT_frame_up_to_date): Use it here...
2745 * w32term.c (w32_frame_up_to_date): ...here...
2746 * xterm.c (XTframe_up_to_date): ...and here...
2747 * nsterm.m (ns_frame_up_to_date): ...but not here.
2748 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2750 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2751 Do not check whether GC is in progress.
2753 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2755 * xdisp.c (window_buffer_changed): New function.
2756 (update_menu_bar, update_tool_bar): Use it to
2757 simplify large 'if' statements.
2758 (redisplay_internal): Generalize commonly used
2759 'tail' and 'frame' local variables.
2761 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2763 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2764 with Windows system header.
2766 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2768 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2769 * alloc.c: Assume unistd.h exists.
2770 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2771 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2772 (getwd) [USG]: Remove; no longer needed.
2773 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2774 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2775 * w32.h (getcwd): Remove decl.
2777 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2779 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2780 Make it set selected_window as well.
2781 (update_tool_bar): Use it.
2783 2012-11-21 Ken Brown <kbrown@cornell.edu>
2785 * emacs.c (main): Set the G_SLICE environment variable for all
2786 Cygwin builds, not just GTK builds. See
2787 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2789 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2791 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2792 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2793 Define for the MSVC compiler.
2795 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2797 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2798 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2799 dostounix_filename. Prevents crashes down the road, because
2800 dostounix_filename assumes it gets a unibyte string.

2809 * eval.c (Fcommandp): Ignore Qunbound.
2810 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2811 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2812 Test NILP rather than Qunbound.
2813 (Ffmakunbound): Set to Qnil.
2814 (Fsymbol_function): Never signal an error.
2815 (Finteractive_form): Ignore Qunbound.
2817 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>

2826 decide whether all windows or frames should be updated.
2827 (window_outdated): New function.
2828 (text_outside_line_unchanged_p, redisplay_window): Use it.
2829 (redisplay_internal): Likewise. Fix indentation.
2831 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2833 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2834 (syms_of_eval): Remove corresponding defsubr.
2835 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2837 2012-11-19 Daniel Colascione <dancol@dancol.org>
2839 * w32fns.c (Fx_file_dialog):
2840 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2841 cygwin_convert_file_name*.
2843 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2844 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2846 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2848 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2850 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2852 * w32select.c: Include w32common.h before w32term.h, so that
2853 windows.h gets included before w32term.h uses some of its
2854 features, see below.
2856 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2858 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2860 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2862 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2864 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2865 (ns_select): Return at once if events are held (Bug#12834).
2867 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2869 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2870 Needed following 2012-10-20 change. (Bug#12902)
2872 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2874 * w32proc.c (waitpid): Remove unused label get_result.
2876 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2878 * makefile.w32-in (SYSWAIT_H): New macro.
2879 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2880 ($(BLD)/sysdep.$(O)): Update dependencies.
2882 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2884 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2885 * callproc.c (relocate_fd): Assume F_DUPFD.
2886 * emacs.c, term.c (O_RDWR): Remove.
2887 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2888 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2889 * nsterm.m: Assume <fcntl.h> exists.
2890 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2891 (create_pty, Fmake_network_process, server_accept_connection)
2892 (wait_reading_process_output, init_process_emacs):
2894 (wait_reading_process_output): Put in a special case for WINDOWSNT
2895 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2896 It's not clear this is needed, but it's a more-conservative change.
2897 (create_process): Assume FD_CLOEXEC.
2898 (create_process, create_pty): Assume O_NOCTTY.
2899 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2900 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2901 Omit if not DOS_NT, since F_GETFL is not defined there.
2902 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2903 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2905 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2906 lack it, since gnulib guarantees this.
2907 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2909 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2911 * w32.c (faccessat): Pretend that directories have the execute bit
2912 set. Emacs expects that, e.g., in files.el:cd-absolute.
2914 * w32proc.c (create_child): Don't clip the PID of the child
2915 process to fit into an Emacs integer, as this is no longer a
2917 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2918 reaping only the process specified by PID argument, if that is
2919 positive. Use PID instead of dead_child to know which process to
2920 reap. Wait for the child to die only if WNOHANG is not in
2922 (sys_select): Don't set dead_child.
2924 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2925 as it is no longer needed.
2927 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2929 (record_child_status_change): Remove the setting of
2930 record_at_most_one_child for the !WNOHANG case.
2932 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2934 Fix problems in ns port found by static checking.
2935 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2936 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2937 not to process group.
2938 (ns_select): Use emacs_write, not write, as that's more robust
2939 in the presence of signals.
2940 (fd_handler:): Check for read errors.
2942 2012-11-16 Glenn Morris <rgm@gnu.org>
2944 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2946 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2948 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2950 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2952 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2953 use the same value of thread handle.
2954 (start_timer_thread): If the timer thread exited (due to error),
2955 clean up by closing the two handles it used. Duplicate the caller
2956 thread's handle here, so it gets duplicated only once, when
2957 launching the timer thread. Set priority of the timer thread, not
2959 (getitimer): Don't duplicate the caller thread's handle here.
2962 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2964 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2967 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2969 Remove no-longer-used pty_max_bytes variable.
2970 * process.c (pty_max_bytes): Remove; unused.
2971 (send_process): Do not set it.
2973 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2975 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2976 Update dependencies.
2978 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2980 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2981 This follows up on the 2012-09-29 patch that removed indirection
2982 for the 'function' field. Reported by Sergey Vinokurov in
2983 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2985 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2987 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2988 different name, as the MS runtime does not have such a function,
2989 and probably never will.) All callers changed. Ignore DIRFD
2990 value if PATH is an absolute file name, to match Posix spec
2991 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2994 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2996 * xdisp.c (echo_area_display, redisplay_internal):
2997 Omit redundant check whether frame_garbaged is set.
2999 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3001 Use faccessat, not access, when checking file permissions (Bug#12632).
3002 This fixes a bug that has been present in Emacs since its creation.
3003 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3004 which must set some sort of record. (Torek's bug report was against
3005 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3006 same common flaw.) See Torek's Usenet posting
3007 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3008 Posted: Fri Apr 8 14:18:56 1983.
3009 * Makefile.in (LIB_EACCESS): New macro.
3011 * callproc.c (init_callproc):
3012 * charset.c (init_charset):
3013 * fileio.c (check_existing, check_executable, check_writable)
3015 * lread.c (openp, load_path_check):
3016 * process.c (allocate_pty):
3018 Use effective UID when checking permissions, not real UID.
3019 * callproc.c (init_callproc):
3020 * charset.c (init_charset):
3021 * lread.c (load_path_check, init_lread):
3022 Test whether directories are accessible, not merely whether they exist.
3023 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3024 * fileio.c (check_existing, check_executable, check_writable)
3026 Use symbolic names instead of integers for the flags, as they're
3028 (check_writable): New arg AMODE. All uses changed.
3029 Set errno on failure.
3030 (Ffile_readable_p): Use faccessat, not stat + open + close.
3031 (Ffile_writable_p): No need to call check_existing + check_writable.
3032 Just call check_writable and then look at errno. This saves a syscall.
3033 dir should never be nil; replace an unnecessary runtime check
3034 with an eassert. When checking the parent directory of a nonexistent
3035 file, check that the directory is searchable as well as writable, as
3036 we can't create files in unsearchable directories.
3037 (file_directory_p): New function, which uses 'stat' on most platforms
3038 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3039 (Ffile_directory_p, Fset_file_times): Use it.
3040 (file_accessible_directory_p): New function, which uses a single
3041 syscall for efficiency.
3042 (Ffile_accessible_directory_p): Use it.
3043 * xrdb.c (file_p): Use file_directory_p.
3044 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3045 * lread.c (openp): When opening a file, use fstat rather than
3046 stat, as that avoids a permissions race. When not opening a file,
3047 use file_directory_p rather than stat.
3048 (dir_warning): First arg is now a usage string, not a format.
3049 Use errno. All uses changed.
3050 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3051 that merely introduced a race.
3052 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3053 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3054 and similarly for the other O_* flags.
3055 * w32.c (sys_faccessat): Rename from sys_access and switch to
3056 faccessat's API. All uses changed.
3057 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3058 (magic_db): Rename from magic_file_p.
3059 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3060 char *, so that we don't have to test for file existence
3061 separately from opening the file for reading. This removes a race
3062 fixes a permission-checking problem, and simplifies the code.
3064 (file_p): Remove; no longer needed.
3066 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3068 Omit glyphs initialization at startup.
3069 * dispnew.c (glyphs_initialized_initially_p): Remove.
3070 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3071 (Fredraw_frame): Move actual code from here...
3072 (redraw_frame): ...to here. Add eassert. Adjust comment.
3073 (Fredraw_display): Use redraw_frame.
3074 * xdisp.c (clear_garbaged_frames): Likewise.
3076 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3078 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3079 passed to pint2str and pint2hrstr to be at most the size of the
3080 frame's decode_mode_spec_buffer. This avoids crashes with very
3081 large values of FIELD_WIDTH argument to decode_mode_spec.
3084 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3086 Fix a race with verify-visited-file-modtime (Bug#12863).
3087 Since at least 1991 Emacs has ignored an mtime difference of no
3088 more than one second, but my guess is that this was to work around
3089 file system bugs that were fixed long ago. Since the race is
3090 causing problems now, let's remove that code.
3091 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3092 whose time stamp is off by no more than a second. Insist that the
3093 file time stamps match exactly.
3095 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3097 * frame.h (struct frame): Convert external_tool_bar member to
3098 1-bit unsigned bitfield.
3099 * termhooks.h (struct terminal): Remove mouse_moved member since
3100 all users are long dead. Adjust comment on mouse_position_hook.
3102 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3104 Simplify by using FOR_EACH_FRAME here and there.
3105 * frame.c (next_frame, prev_frame, other_visible_frames)
3106 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3107 * w32term.c (x_window_to_scroll_bar): Likewise.
3108 * window.c (window_list): Likewise.
3109 * xdisp.c (x_consider_frame_title): Likewise.
3110 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3111 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3112 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3113 * xmenu.c (menubar_id_to_frame): Likewise.
3114 * xselect.c (frame_for_x_selection): Likewise.
3115 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3116 (x_window_to_menu_bar): Likewise.
3117 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3119 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3121 * data.c (Qdefalias_fset_function): Now static.
3123 Another tweak to vectorlike_header change.
3124 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3125 Remove, and replace all uses with ...
3126 (next_in_free_list, set_next_in_free_list):
3127 New functions, which respect C's aliasing rules better.
3129 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3131 * window.c (list4i): Rename from 'quad'. All uses changed.
3132 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3134 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3136 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3137 warning about mixing declarations and code in ISO C90.
3139 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3141 * window.c (Fsplit_window_internal): Set combination limit of
3142 new parent window to t iff Vwindow_combination_limit is t;
3143 fixing a regression introduced with the change from 2012-09-22.
3144 (Fset_window_combination_limit): Fix doc-string.
3146 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3148 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3149 amount when the scroll margins are too large. When scrolling
3150 backwards in the buffer, give up if cannot reach point or the
3151 scroll margin within a reasonable number of screen lines.
3152 Fixes point position in window under scroll-up/down-aggressively when
3153 point is positioned many lines beyond the window top/bottom.
3156 * ralloc.c (relinquish): If real_morecore fails to return memory
3157 to the system, don't crash; instead, leave the last heap
3158 unchanged and return. (Bug#12774)
3160 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3162 * lisp.h (AUTOLOADP): New macro.
3163 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3164 * data.c (Ffset): Remove special ad-advice-info handling.
3165 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3167 (Finteractive_form): Simplify.
3168 (Fquo): Don't insist on having at least 2 arguments.
3169 (Qdefalias_fset_function): New var.
3171 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3173 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3177 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3179 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3181 Fix recently introduced crash on MS-Windows (Bug#12839).
3182 * w32term.h (struct scroll_bar): Use convenient header.
3183 (SCROLL_BAR_VEC_SIZE): Remove.
3184 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3186 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3188 Tweak last vectorlike_header change.
3189 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3190 vectorlike object on the free list. This is introduced to avoid
3191 some (but not all) pointer casting and aliasing problems, see
3192 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3193 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3195 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3197 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3199 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3200 been removed, so remove them here also.
3202 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3204 * doc.c (Fdocumentation): Handle new property
3205 dynamic-docstring-function to replace the old ad-advice-info.
3207 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3209 * fns.c (Qeql, hashtest_eq): Now static.
3211 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3213 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3214 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3215 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3216 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3218 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3220 Use same hash function for hashfn_profiler as for hash_string etc.
3221 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3222 * lisp.h (sxhash_combine): New inline function, with the contents
3223 of the old SXHASH_COMBINE.
3224 * profiler.c (hashfn_profiler): Use it, instead of having a
3225 special hash function containing a comparison that always yields 1.
3227 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3229 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3230 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3231 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3234 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3236 * image.c (xpm_make_color_table_h): Fix compiler error because
3237 make_hash_table changed.
3239 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3241 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3243 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3245 Use ad-hoc comparison function for the profiler's hash-tables.
3246 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3247 (make_log): Use them.
3248 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3249 call Fequal any more.

3258 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3259 (hash_lookup, hash_remove_from_table): Move assertion checking of
3260 hashfn result here. Check hash-equality before calling cmpfn.
3261 (Fmake_hash_table): Adjust call to make_hash_table.
3262 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3263 (syms_of_fns): Initialize them.

3268 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
3270 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3272 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3273 value of w32-scroll-lock-modifier is neither nil nor one of the
3274 known key modifiers. (Bug#12806)
3276 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3278 Shrink struct vectorlike_header to the only size field.
3279 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3281 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3282 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3283 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3284 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3285 information from the vector header. Adjust comment.

3295 (enum mem_type): Adjust comment.
3296 (NEXT_IN_FREE_LIST): New macro.
3297 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3298 (Fmake_bool_vector): Likewise.
3299 (struct large_vector): New type to represent allocation unit for
3300 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3301 (large_vectors): Change type to struct large_vector.
3302 (allocate_vector_from_block): Simplify.
3303 (PSEUDOVECTOR_NBYTES): Replace with...
3304 (vector_nbytes): ...new function. Adjust users.
3305 (sweep_vectors): Adjust processing of large vectors.
3306 (allocate_vectorlike): Likewise.
3307 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3308 Add easserts. Adjust XSETPVECTYPESIZE usage.
3309 (allocate_buffer): Use BUFFER_PVEC_INIT.
3310 (live_vector_p): Adjust to match large vector.
3311 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3312 * buffer.h (struct buffer): Add next member.
3313 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3315 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3316 * fns.c (internal_equal): Adjust to match enum pvec_type change.

3321 (xvecsize): New command.
3323 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3325 * keyboard.c (event_to_kboard): Do not dereference
3326 frame_or_window field of SELECTION_REQUEST_EVENT
3327 and SELECTION_CLEAR_EVENT events (Bug#12814).
3328 * xterm.h (struct selection_input_event): Adjust comment.
3330 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3332 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3333 such as Scroll Lock, if the respective keys are treated as
3334 function keys, not as modifiers. This avoids destroying non-ASCII
3335 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3337 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3339 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3341 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3343 Restore some duplicate definitions (Bug#12814).
3344 This undoes part of the 2012-11-03 changes. Some people build
3345 with plain -g rather than with -g3, and they need the duplicate
3346 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3347 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3348 Define as macros, as well as as enums or as constants.
3350 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3352 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3353 to keypad keys (Bug#12816).
3355 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3357 Minor adjustments of recently-changed frame functions.
3358 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3359 known to be a frame (we're in the FRAMEP branch).
3360 * lisp.h (Qframep): Remove decl. frame.h declares this.
3361 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3362 since they're meant for Lisp fixnum values.
3364 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3366 * window.c (Fwindow_combination_limit): Revert to the only
3367 required argument and adjust docstring as suggested in
3368 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3369 by Martin Rudalics <rudalics@gmx.at>.
3371 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3373 Widely used frame validity and checking functions.
3374 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3375 * frame.c (decode_live_frame, decode_any_frame): New functions.
3376 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3377 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3378 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3379 (Fframe_pointer_visible_p): Use decode_any_frame.

3382 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3383 (Fframe_focus): Likewise. Allow zero number of arguments.
3385 (frame_buffer_list, frame_buffer_predicate): Remove.
3386 * lisp.h (frame_buffer_predicate): Remove prototype.
3387 * buffer.c (Fother_buffer): Use decode_any_frame.
3388 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3389 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3390 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3391 (Fclose_font, Ffont_info): Use decode_live_frame.
3392 * fontset.c (check_fontset_name): Likewise.
3393 * terminal.c (Fframe_terminal): Likewise.
3394 * w32fns.c (check_x_frame): Likewise.
3395 * window.c (Fminibuffer_window, Fwindow_at)
3396 (Fcurrent_window_configuration): Likewise.
3397 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3398 Likewise. Allow zero number of arguments. Adjust docstring.
3399 * dispnew.c (Fredraw_frame): Likewise.
3400 * xfaces.c (frame_or_selected_frame): Remove.
3401 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3402 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3403 (Fframe_face_alist): Use decode_live_frame.
3404 * xfns.c (check_x_frame): Likewise.
3406 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3408 * window.c (quad): New function.
3409 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3410 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3411 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3412 (Fwindow_line_height): Use it.
3413 (Fwindow_fringes): Use list3.
3414 (Fwindow_scroll_bars): Use list4.
3415 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3416 (Fwindow_combination_limit): Allow zero number of arguments.
3418 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3420 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3422 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3423 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3424 file descriptor 2 for standard error. (Bug#12805)
3426 2012-11-05 Chong Yidong <cyd@gnu.org>
3428 * process.c (wait_reading_process_output): Revert previous change.
3430 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3432 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3433 This removes code that has been obsolete since around 1990.
3434 * callproc.c (Fcall_process):
3436 * process.c (create_process):
3437 * term.c (dissociate_if_controlling_tty):
3438 Assume setsid exists.
3439 * callproc.c (child_setup): Assume setpgid exists and behaves as
3440 per POSIX.1-1988 or later.
3441 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3442 * emacs.c (shut_down_emacs):
3443 * sysdep.c (sys_suspend, init_foreground_group):
3444 Assume getpgrp behaves as per POSIX.1-1998 or later.
3445 * msdos.c (setpgrp): Remove.
3446 (tcgetpgrp, setpgid, setsid): New functions.
3447 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3448 * term.c (no_controlling_tty): Remove; unused.
3449 * w32proc.c (setpgrp): Remove.
3450 (setsid, tcgetpgrp): New functions.
3452 Simplify by assuming __fpending.
3453 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3454 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3455 Do not assume that __fpending's result fits in int.
3457 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3459 Remove EMACS_OUTQSIZE+sleep hack.
3460 * dispnew.c (update_frame_1): Remove hack for terminals slower
3461 than 2400 bps, which throttled Emacs by having it sleep.
3462 This code hasn't worked since at least 2007, when the multi-tty stuff
3463 was added, and anyway those old terminals are long dead.
3464 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3465 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3467 Fix data-loss with --version (Bug#9574).
3468 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3469 as we can't assume that emacs_strerror is initialized, and strerror
3470 is good enough here.
3471 (main): Invoke atexit earlier, to catch earlier instances of
3472 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3474 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3476 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3477 (keyDown): Remap keypad keys to X11 virtual key codes.
3479 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3481 Fix data-loss with --batch (Bug#9574).
3482 * emacs.c: Include <close-stream.h>.
3483 (close_output_streams): New function.
3484 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3485 and handles errors appropriately.
3486 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3489 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3490 The symptom is a diagnostic "GLib-WARNING **: In call to
3491 g_spawn_sync(), exit status of a child process was requested but
3492 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3493 waitpid(), so exit status can't be returned." The diagnostic
3494 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3495 The real bug is a race condition between Emacs and glib: Emacs
3496 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3497 so that glib can't find it. Work around the bug by invoking
3498 waitpid only on subprocesses that Emacs itself creates.
3499 * process.c (create_process, record_child_status_change):
3500 Don't use special value -1 in pid field, as the caller now must
3501 know the pid rather than having the callee infer it.
3502 The inference was sometimes incorrect anyway, due to another race.
3503 (create_process): Set new 'alive' member if child is created.
3504 (process_status_retrieved): New function.
3505 (record_child_status_change): Use it.
3506 Accept negative 1st argument, which means to wait for the
3507 processes that Emacs already knows about. Move special-case code
3508 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3509 processes that have already been waited for, by testing and
3510 clearing new 'alive' member.
3511 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3512 now does this internally.
3513 (handle_child_signal): Let record_child_status_change do all
3514 the work, since we do not want to reap all exited child processes,
3515 only the child processes that Emacs itself created.
3516 * process.h (Lisp_Process): New boolean member 'alive'.
3518 Omit duplicate definitions no longer needed with gcc -g3.
3519 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3520 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3521 Define only as macros. There's no longer any need to also define
3522 these symbols as enums or as constants, since we now assume
3523 gcc -g3 when debugging.
3525 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3527 * lisp.mk: Adjust comments to the fact that term/internal is now
3528 loaded from loadup.el.
3530 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3531 (msdos_fatal_signal): New function.
3532 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3535 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3536 for GCC versions before 4.
3537 (emacs_raise): Define to call msdos_fatal_signal.
3539 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3540 iterator when starting in the middle of a display or overlay
3543 2012-11-03 Chong Yidong <cyd@gnu.org>
3545 * process.c (wait_reading_process_output): Clean up the last
3548 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3550 * process.c (wait_reading_process_output): Avoid a race condition
3551 with SIGIO delivery (Bug#11536).
3553 2012-11-03 Chong Yidong <cyd@gnu.org>
3555 * buffer.c (cursor_type): Untabify docstring.
3557 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3559 * frame.h (struct frame): Drop can_have_scroll_bars member
3560 which is meaningless for a long time. Adjust comments.
3561 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3562 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3564 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3566 * window.c (decode_next_window_args): Update window arg after
3567 calling decode_live_window and so fix crash reported at
3568 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3569 by Juanma Barranquero <lekktu@gmail.com>.
3570 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3571 * font.c (Ffont_at): Likewise.
3573 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3575 * widget.c (resize_cb): New function.
3576 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3577 (EmacsFrameResize): Check if all is up to date before changing frame
3580 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3582 Implement backtrace output for fatal errors on MS-Windows.
3583 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3584 (BACKTRACE_LIMIT_MAX): New macro.
3585 (w32_backtrace): New function.
3586 (emacs_abort): Use w32_backtrace when the user chooses not to
3587 attach a debugger. Update the text of the abort dialog.
3589 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3591 Window-related stuff cleanup here and there.
3592 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3593 Use decode_any_window.
3594 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3595 * xdisp.c (Fformat_mode_line): Likewise.
3596 * font.c (Ffont_at): Use decode_live_window.
3597 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3598 * window.c (decode_next_window_args): Likewise.
3599 (decode_any_window): Remove static.
3600 * window.h (decode_any_window): Add prototype.
3601 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3602 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3605 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3607 Remove pad from struct input_event.
3608 * termhooks.h (struct input_event): Remove padding field.
3610 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3611 member is never cons for a long time. Adjust comment.
3612 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3613 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3614 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3615 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3617 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3619 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3621 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3623 Fix crash when using Emacs as commit editor for git (Bug#12697).
3624 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3625 and it is configured in conf_post.h.
3626 (Fcall_process): Don't invoke both setsid and setpgid; the former
3627 is enough, if it exists.
3628 * callproc.c (Fcall_process, child_setup):
3629 * process.c (create_process): Use setpgid.
3630 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3632 * dispnew.c (init_display): Initialize the foreground group
3633 if we are running a tty display.
3634 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3635 * lisp.h (init_foreground_group): New decl.
3636 * sysdep.c (inherited_pgroup): New static var.
3637 (init_foreground_group, tcsetpgrp_without_stopping)
3638 (narrow_foreground_group, widen_foreground_group): New functions.
3639 (init_sys_modes): Narrow foreground group.
3640 (reset_sys_modes): Widen foreground group.
3642 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3644 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3646 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3648 * minibuf.c (read_minibuf): Restore current buffer since
3649 choose_minibuf_frame calling Fset_frame_selected_window may
3650 change it (Bug#12766).
3652 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3654 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3656 2012-10-30 Kenichi Handa <handa@gnu.org>
3658 * font.c (Ffont_at): If WINDOW is specified and it is not
3659 displaying the current buffer, signal an error.
3661 2012-10-29 Daniel Colascione <dancol@dancol.org>
3663 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3664 In preparation for fixing bug#12739, move these functions from
3667 * coding.h, coding.c: ... to here, and compile them only when
3668 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3669 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3671 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3673 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3674 (timer_loop, getitimer, setitimer): Use it instead of
3675 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3677 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3680 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3682 * nsterm.m (NO_APPDEFINED_DATA): New define.
3683 (last_appdefined_event_data): New variable
3684 (last_appdefined_event): Remove.
3685 (ns_select): Initialize t from last_appdefined_event_data instead
3686 of [last_appdefined_event data1].
3687 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,

3692 * frame.c (x_set_font): Catch internal error.
3694 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3696 Avoid overflow in w32 implementation of interval timers.
3697 When possible, for ITIMER_PROF count only times the main thread
3699 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3700 'volatile ULONGLONG' types. All the other data which was
3701 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3702 (GetThreadTimes_Proc): New typedef.
3703 (w32_get_timer_time): New function, returns a suitable time value
3705 (timer_loop): Enter critical section when accessing ULONGLONG
3706 values of the itimer_data struct, as these accesses are no longer
3707 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3708 Remove unused variable.
3709 (init_timers): Initialize s_pfn_Get_Thread_Times.
3710 (start_timer_thread): Don't assign itimer->caller_thread here.
3711 (getitimer): Assign itimer->caller_thread here.

3717 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3718 mouse movement events if the menu bar is active. This avoids
3719 producing a busy "hour-glass" cursor by Windows if the mouse
3720 pointer is positioned over a tooltip shown for some menu item.
3722 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3724 Don't assume process IDs fit in int.
3725 * emacs.c (shut_down_emacs) [!DOS_NT]:
3726 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3727 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3728 Use pid_t, not int, to store process IDs, as 'int'
3729 is not wide enough on a few platforms (e.g., AIX and IRIX).
3731 2012-10-23 Kenichi Handa <handa@gnu.org>
3733 The following change is to make face-font-rescale-alist work
3734 correctly for non-ASCII fonts.

3756 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3758 Port to OpenBSD 5.1.
3759 * frame.c (Fmouse_position, Fmouse_pixel_position):
3760 * xdisp.c (produce_stretch_glyph):
3761 Declare local vars only when they're needed.
3762 This is clearer and avoids a warning on OpenBSD about unused vars.

3766 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3767 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3768 as our definition clashes with OpenBSD's.
3769 * xfaces.c (load_face_colors, check_lface_attrs)
3770 (get_lface_attributes_no_remap, get_lface_attributes)
3771 (lface_fully_specified_p, x_supports_face_attributes_p)
3772 (tty_supports_face_attributes_p, face_fontset, realize_face)
3773 (realize_x_face, realize_tty_face):
3774 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3775 merely Lisp_Object *. This is more informative and avoids
3776 a warning on OpenBSD about accessing beyond an object's size.
3778 2012-10-20 Chong Yidong <cyd@gnu.org>
3780 * lread.c (Fload): Doc fix (Bug#12592).

3806 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3807 (staticpro): If we run out of staticpro slots, die with an
3808 informative error instead of just calling emacs_abort.
3810 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3812 Fix two flaws reported by Dmitry Antipov.

4070 the same pointer-to-int (now pointer-to-boolean) &input_pending,

4072 input_pending. All callers changed.

4123 2012-10-08 Daniel Colascione <dancol@dancol.org>
4125 * xdisp.c (start_hourglass): Call w32_note_current_window when

4127 build that caused Emacs to display the hourglass cursor forever.
4129 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4130 which is broken under remote desktop, calculate the number of
4131 colors available for a display based on the display's number of

4169 2012-10-08 Daniel Colascione <dancol@dancol.org>
4171 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4172 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4173 accidental message numbering hole. Change other messages to
4176 * w32select.h (HAVE_W32SELECT): Remove.
4178 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4179 w32common.h instead of w32heap.h.
4181 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4182 (get_allocation_unit, get_processor_type, get_w32_major_version)
4183 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4184 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4185 (OS_NT, os_subtype, cache_system_info): Move declarations to
4188 * w32heap.c: Include w32common.h.
4189 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4190 (w32_minor_version, w32_build_number, w32_subtype):
4191 Remove duplicate definitions.
4193 * w32fns.c: Include w32common.h; include w32heap.h only in
4196 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4197 Use `report_file_error' instead of `error' in order to better
4198 inform users of what went wrong. Increase NTGUI_UNICODE file
4199 dialog box file name length to 32k, the maximum allowed by the NT
4202 * w32common.h: New file.
4203 (ROUND_UP, ROUND_DOWN, get_page_size)
4204 (get_allocation_unit, get_processor_type, get_w32_major_version)
4205 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4206 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4207 (OS_NT, os_subtype, cache_system_info): Move here.
4209 * unexw32.c, unexcw.c: Include w32common.h.
4211 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4212 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4213 to call syms_of_w32select.
4215 * cygw32.h: Remove obsolete EXFUN declarations.
4217 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4219 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4220 of w32inevt.o from SOME_MACHINE_OBJECTS.
4222 2012-10-08 Daniel Colascione <dancol@dancol.org>
4224 * image.c: Permanent fix for JPEG compilation issue --- limit
4225 jpeglib `boolean' redefinition to Cygwin builds.
4227 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4229 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4231 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4234 2012-10-08 Daniel Colascione <dancol@dancol.org>
4236 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4237 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4238 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4239 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4240 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4241 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4242 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4243 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4244 now a supported configuration.
4246 * Makefile.in: consolidate image variables into LIBIMAGE; add
4247 W32_OBJ and W32_LIBS. Compile new files.
4250 (_DebPrint) declare tracing facility for W32 debugging. We need
4251 to unify tracing later.
4253 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4254 unconditional use of W32 Unicode functions. Cygwin runs only on
4255 100% Unicode operating systems.
4257 * cygw32.c: New file. Define Cygwin-specific facilities.
4258 (Fcygwin_convert_path_to_windows)
4259 (Fcygwin_convert_path_from_windows): New user functions for
4260 accessing Cygwin path-munging routines.
4262 * cygw32.h: New file.
4263 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4264 UTF-16LE strings temporarily inside non-Lisp-visible string
4267 (w32_strerror): Just what it says on the tin.
4269 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4270 also run for Cygwin; both systems have the same problem with using
4271 GUI facilities in a forked child. Also call syms_of_cygw32,
4272 syms_of_w32select in correct places.
4274 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4275 needs fork-then-exec for daemon launching.
4277 * font.h: Include frame.h.
4279 * image.c: Use the image library cache machinery only when we're
4280 compiling for native WINDOWSNT; Cygwin can use shared libraries
4281 like any other Unixlike system.
4283 * keyboard.c: Clarify a comment regarding the input loop.
4285 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4286 functions directly instead of trying to detect at runtime that our
4287 host operating system supports them. We make this change for two
4288 reasons: Cygwin lacks support for the multibyte character
4289 conversion functions used by the legacy menu code, and Cygwin
4290 never needs to rely on non-Unicode APIs.
4292 * unexw32.c (hinst): Declare extern.
4294 * w32.c: Change header order;
4295 (w32_strerror): Move to w32fns.c because we need it for
4296 non-WINDOWSNT builds.
4298 * w32.h: Add #error macro to make sure we don't include w32.h for
4299 Cygwin builds. Remove w32select declarations.
4301 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4302 w32fns.c. w32console.c is WINDOWSNT-only.
4304 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4305 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4307 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4308 (w32_major_version, w32_minor_version, w32_build_number)
4309 (os_subtype, sound_type): Define here
4310 (w32_defined_color): Make color parameter const for consistency
4311 with other _defined_color functions.
4312 (w32_createwindow): Unconditionally call w32_init_class instead of
4313 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4314 through the code is complex and unnecessary because class
4315 registration is practically free.
4316 (w32_name_of_message): New EMACSDEBUG-only function.
4317 (Fset_message_beep): Move here
4318 (Fx_open_connection): Require that the display name for Windows be
4319 "w32" for consistency, emacsclient disambiguation, and maybe, one
4320 day, multi-window-system support.
4321 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4322 Cygwin files for W32 GUI facilities, since these clearly don't
4323 expect Cygwin names.
4324 (_DebPrint): Define.
4325 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4326 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4327 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4328 (w32_last_error): Remove.
4330 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4332 * w32heap.c (syspage_mask): Declare here.
4333 (cache_system_info): Remove.
4335 * w32inevt.c (faked_key): Define globally, not statically.
4336 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4337 (w32_console_toggle_lock_key): Move to w32fns.c.
4339 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4341 * w32proc.c (_DebPrint): Move to w32fns.c.
4342 * w32select.c: Include string.h, stdio.h for Cygwin.
4343 * w32select.h: New File.
4345 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4347 (w32_message_fd): New variable. Under Cygwin, holds the file
4348 descriptor the system used to tell us about pending thread
4351 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4352 that prevented compilation under non-WINDOWSNT systems.
4354 (w32_initialize): Open /dev/windows and assign it to
4355 w32_message_fd. Provide w32 feature.
4357 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4358 (WM_EMACS_INPUT_READY): add.
4359 (prepend_msg, w32_message_fd): Declare globally.
4362 (keyboard_handle): Use only when WINDOWSNT.
4363 (notify_msg_ready): New function. Posts a message to the main
4364 thread's message queue under CYGWIN, which wakes up the main
4365 thread from select(2) by making the /dev/windows file descriptor
4366 ready. Under WINDOWSNT, it sets an event the same way the old
4369 (post, prepend_msg): Actually call notify_msg_ready instead of
4370 setting the input event directly.
4372 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4374 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4375 but it still has blocs in it, don't return it to the system,
4376 instead of aborting. (Bug#12402)
4378 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4380 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4382 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4383 MAC_OS_X_VERSION_10_6.
4384 (syms_of_nsterm): Remove comment about Panther and above for
4386 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4387 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4388 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4390 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4391 MAC_OS_X_VERSION_10_4.
4393 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4394 MAC_OS_X_VERSION_10_2.
4396 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4398 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4399 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4401 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4402 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4403 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4404 Remove ns_in_resize check.
4405 (ns_clear_frame_area): Remove resize handle code.
4407 * nsfns.m (ns_in_resize): Remove.
4408 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4409 Remove ns_in_resize check.
4411 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4413 Improve sys_siglist detection.
4414 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4415 defined as a macro, as is done in Solaris.
4416 (sys_siglist_entries): New macro.
4417 (save_strsignal): Use it.
4418 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4419 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4421 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4423 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4424 fullscreen/Fullscreen.
4426 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4427 tobar_height is new.
4429 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4430 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4431 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4432 (windowDidResize:): Check for correct window if old style fullscreen.
4433 Capitalize word in comment. Remove incorrect comment.
4434 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4435 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4436 error in drawing background.
4437 (toggleFullScreen:): Remove comment. Rearrange calls.
4438 Set toolbar values to zero, save old height in tobar_height.
4439 Restore tool bar height when leaving fullscreen.
4440 (canBecomeMainWindow): New function.
4442 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4444 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4446 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4448 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4450 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4451 that time stamps of directories could also be changed.
4452 Don't request the too broad GENERIC_WRITE, only the more restrictive
4453 FILE_WRITE_ATTRIBUTES access rights.
4455 * fileio.c (Fset_file_times): Special-case ignoring errors for
4456 directories only on MSDOS, not on MS-Windows.
4458 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4460 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4462 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4464 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4465 see whether CreateFile failed.
4467 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4469 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4470 to avoid similar races.
4471 * keyboard.c (pending_signals): Now bool, not int.
4473 Port timers to OpenBSD, plus check for timer failures.
4474 OpenBSD problem reported by Han Boetes.
4475 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4477 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4478 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4479 like OpenBSD, which has timer_settime but does not declare it.
4480 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4481 whether to use itimerspec-related primitives. All uses of
4482 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4484 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4486 * profiler.c (handle_profiler_signal): Fix a malloc race
4487 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4489 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4491 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4493 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4495 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4496 consistent with the change in return value of 'safe_strsignal'.
4498 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4500 Prefer plain 'static' to 'static inline' (Bug#12541).
4501 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4502 (bidi_set_sor_type, bidi_push_embedding_level)
4503 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4504 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4505 (bidi_cache_search, bidi_cache_ensure_space)
4506 (bidi_cache_iterator_state, bidi_cache_find)
4507 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4508 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4509 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4510 Now 'static', not 'static inline'.
4512 Count overruns when profiling; change units to ns.
4513 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4514 Give extra weight to samples after overruns, to attempt to count
4515 the time more accurately.
4516 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4517 the underlying primitives nominally do ns.
4518 (Fprofiler_cpu_start): Document the change. Mention that
4519 the sampling intervals are only approximate.
4521 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4523 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4525 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4526 case for the special 0 coding-system.
4528 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4529 (Fmake_overlay): Remove redundant tests.
4530 (fix_start_end_in_overlays): Remove redundant recentering.
4532 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4534 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4535 Update dependencies.
4537 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4539 Fix a malloc race condition involving strsignal.
4540 A signal can arrive in the middle of a malloc, and Emacs's signal
4541 handler can invoke strsignal, which can invoke malloc, which is
4542 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4543 Fix it by altering the signal handler so that it does not invoke
4545 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4546 * process.c (status_message): Use const pointer, in case strsignal
4547 is #defined to safe_strsignal.
4548 * sysdep.c (sys_siglist, init_signals): Always define and
4549 initialize a substitute sys_siglist if the system does not define
4550 one, even if HAVE_STRSIGNAL.
4551 (safe_strsignal): Rename from strsignal. Always define,
4552 using sys_siglist. Return a const pointer.
4553 * syssignal.h (safe_strsignal): New decl.
4554 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4556 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4558 * w32proc.c (timer_loop): Fix code that waits for timer
4559 expiration, to avoid high CPU usage.
4561 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4563 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4564 (sweep_weak_table): Remove redundant prototypes.
4566 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4568 * emacs.c: Move the inclusion of TERM_HEADER after including
4569 windows.h on WINDOWSNT. This avoids compilation problems with
4572 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4574 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4575 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4576 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4577 as the previous version used 'void *'.
4579 * ralloc.c (ROUNDUP): Fix last change.
4580 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4583 * w32proc.c <disable_itimers>: New static flag.
4584 (init_timers): Initialize it to zero, after creating the critical
4585 sections used by the timer threads.
4586 (term_timers): Set to 1 before deleting the critical sections.
4587 (getitimer, setitimer): If disable_itimers is non-zero, return an
4588 error indication without doing anything. Reported by Fabrice
4589 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4590 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4592 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4595 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4596 term_ntproc after all the other bookkeeping, to get timers working
4597 as long as possible.
4599 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4601 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4602 Suggested by Juri Linkov in
4603 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4605 Prefer plain 'static' to 'static inline' (Bug#12541).
4606 With static functions, modern compilers inline pretty well by
4607 themselves; advice from programmers often hurts as much as it helps.
4608 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4609 this change shrinks the text size of the Emacs executable by 1.1%
4610 without affecting CPU significantly in my benchmark.
4611 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4612 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
4613 (mark_maybe_object, mark_maybe_pointer, bounded_number):

4615 (bset_auto_fill_function, bset_auto_save_file_format)
4616 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

4912 Prefer timer_settime if available, and prefer
4913 thread cputime clocks, then process cputime clocks, then

5095 now return bool, not int. All uses changed.
5096 * image.c: Omit unnecessary static decls.
5097 (x_create_bitmap_mask, x_build_heuristic_mask):
5098 Return void, not int, since callers don't care about the return value.

5133 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5135 Move pid_t related decls out of lisp.h.
5136 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5137 (interruptible_wait_for_termination):
5138 Move these decls from lisp.h to syswait.h, since they use pid_t.
5139 Needed on FreeBSD; see Herbert J. Skuhra in
5140 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5141 * callproc.c: Include syswait.h.

5161 Use bool for boolean.
5162 * gtkutil.c (xg_update_frame_menubar):

5187 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5189 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5190 fatal_error_backtrace.
5192 * w32proc.c (sys_kill): Undo last change: don't do anything when
5193 invoked to deliver SIGABRT to our own process. This is now
5194 handled by emacs_raise.
5196 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5198 * w32term.c (w32_read_socket): Remove leftover reference to
5199 interrupt_input_pending.
5201 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5203 Do not use SA_NODEFER.
5204 Problem reported by Dani Moncayo in
5205 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5207 * sysdep.c (emacs_abort): Do not reset signal handler.
5208 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5209 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5210 wanted even on POSIXish hosts, and it doesn't work on Windows.
5212 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5214 * xterm.c (x_term_init): Call fixup_locale before and after calling
5215 gtk_init (Bug#12392).
5217 2012-09-23 Chong Yidong <cyd@gnu.org>
5219 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5220 Vdynamic_library_alist.
5222 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5223 (Fgnutls_available_p): Caller changed.
5225 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5226 (Flibxml_parse_xml_region): Likewise.
5228 * dispextern.h (struct image_type): Remove arg from init function.
5230 * image.c (Finit_image_library, lookup_image_type)
5231 (define_image_type): Remove now-unneeded second arg.
5232 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5233 (init_tiff_functions, init_gif_functions, init_svg_functions):
5234 Arglist and w32_delayed_load calling convention changed.
5235 (gs_type): Remove init_gs_functions; there is no such function.
5236 (valid_image_p, make_image): Fix caller to lookup_image_type.
5238 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5240 Simplify and avoid signal-handling races (Bug#12471).
5242 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5243 Avoid recursive loop if there's a fatal error in the function itself.
5244 * atimer.c (pending_atimers):
5245 * blockinput.h: Don't include "atimer.h"; no longer needed.
5246 (interrupt_input_pending): Remove. All uses removed.
5247 pending_signals now counts both atimers and ordinary interrupts.
5248 This is less racy than having three separate pending-signal flags.
5249 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5251 Rename from their upper-case counterparts BLOCK_INPUT,
5252 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5253 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5254 This makes it easier to access volatile variables more accurately.
5255 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5256 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5257 that's more reliable if the code is buggy and sets
5258 interrupt_input_blocked to a negative value. All uses changed.
5259 * atimer.c (deliver_alarm_signal):
5260 Remove. No need to deliver this to the parent; any thread can
5261 handle this signal now. All uses replaced by underlying handler.
5262 * atimer.c (turn_on_atimers):
5263 * dispnew.c (handle_window_change_signal):
5264 * emacs.c (handle_danger_signal):
5265 * keyboard.c (kbd_buffer_get_event):
5266 Don't reestablish signal handler; not needed with sigaction.
5267 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5269 Rework to avoid unnecessary accesses to volatile variables.
5270 (UNBLOCK_INPUT_TO): Now a function.
5271 (totally_unblock_input, unblock_input): New decls.
5272 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5273 (init_data): Remove. Necessary stuff now done in init_signal.
5274 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5275 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5276 (fatal_error_code): Remove; no longer needed.
5277 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5278 it doesn't always backtrace. All uses changed. No need to reset
5279 signal to default, since sigaction and/or die does that for us now.
5280 Use emacs_raise (FOO), not kill (getpid (), FOO).
5281 (main): Check more-accurately whether we're dumping.
5282 Move fatal-error setup to sysdep.c
5283 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5284 * gtkutil.c (xg_get_file_name, xg_get_font):
5285 Remove no-longer-needed signal-mask manipulation.
5286 * keyboard.c, process.c (POLL_FOR_INPUT):
5287 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5288 * keyboard.c (read_avail_input): Remove.
5289 All uses replaced by gobble_input.
5290 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5291 (kbd_buffer_store_event_hold, gobble_input):
5292 (record_asynch_buffer_change) [USABLE_SIGIO]:
5293 (store_user_signal_events):
5294 No need to mess with signal mask.
5295 (gobble_input): If blocking input and there are terminals, simply
5296 set pending_signals to 1 and return. All hooks changed to not
5297 worry about whether input is blocked.
5298 (process_pending_signals): Clear pending_signals before processing
5299 them, in case a signal comes in while we're processing.
5300 By convention callers now test pending_signals before calling us.
5301 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5302 New functions, to support changes to blockinput.h.
5303 (handle_input_available_signal): Now extern.
5304 (reinvoke_input_signal): Remove. All uses replaced by
5306 (quit_count): Now volatile, since a signal handler uses it.
5307 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5308 All callers changed. Block SIGINT only if not already blocked.
5309 Clear sigmask reliably, even if Fsignal returns, which it can.
5310 Omit unnecessary accesses to volatile var.
5311 (quit_throw_to_read_char): No need to restore sigmask.
5312 * keyboard.c (gobble_input, handle_user_signal):
5313 * process.c (wait_reading_process_output):
5314 Call signal-handling code rather than killing ourselves.
5315 * lisp.h: Include <float.h>, for...
5316 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5317 (pending_signals): Now volatile.
5318 (syms_of_data): Now const if IEEE floating point.
5319 (handle_input_available_signal) [USABLE_SIGIO]:
5320 (terminate_due_to_signal, record_child_status_change): New decls.
5321 * process.c (create_process): Avoid disaster if memory is exhausted
5322 while we're processing a vfork, by tightening the critical section
5324 (send_process_frame, process_sent_to, handle_pipe_signal)
5325 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5327 (send_process): No need for setjmp/longjmp any more, since the
5328 SIGPIPE stuff is now gone. Instead, report an error if errno
5330 (record_child_status_change): Now extern. PID and W are now args.
5331 Return void, not bool. All callers changed.
5332 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5333 Remove. All uses removed. This bug should be fixed now in a
5335 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5336 and record the child status change directly. This avoids the
5337 need to futz with the signal mask.
5338 (process_fatal_action): Move here from emacs.c.
5339 (emacs_sigaction_flags): New function, containing
5340 much of what used to be in emacs_sigaction_init.
5341 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5342 caught by emacs, to make races less likely.
5343 (deliver_process_signal): Rename from handle_on_main_thread.
5345 (BACKTRACE_LIMIT_MAX): Now at top level.
5346 (thread_backtrace_buffer, threadback_backtrace_pointers):
5348 (deliver_thread_signal, deliver_fatal_thread_signal):
5349 New functions, for more-accurate delivery of thread-specific signals.
5350 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5351 (deliver_arith_signal): Handle in this thread, not
5352 in the main thread, since it's triggered by this thread.
5353 (maybe_fatal_sig): New function.
5354 (init_signals): New arg DUMPING so that we can be more accurate
5355 about whether we're dumping. Caller changed.
5356 Treat thread-specific signals differently from process-general signals.
5357 Block all signals while handling fatal error; that's safer.
5358 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5360 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5361 Ignore SIGPIPE unless batch.
5362 (emacs_backtrace): Output backtrace for the appropriate thread,
5363 which is not necessarily the main thread.
5364 * syssignal.h: Include <stdbool.h>.
5365 (emacs_raise): New macro.
5366 * xterm.c (x_connection_signal): Remove; no longer needed
5367 now that we use sigaction.
5368 (x_connection_closed): No need to mess with sigmask now.
5369 (x_initialize): No need to reset SIGPIPE handler here, since
5370 init_signals does this for us now.
5372 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5374 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5375 background rect may be larger (Bug#12245).
5377 2012-09-23 Chong Yidong <cyd@gnu.org>
5379 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5381 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5383 * .gdbinit: Just stop at fatal_error_backtrace.
5384 See Stefan Monnier's request in
5385 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5386 Remove no-longer-used query of system type.
5388 2012-09-22 Chong Yidong <cyd@gnu.org>
5390 * search.c (Freplace_match): Doc fix (Bug#12325).
5392 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5394 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5395 (Fline_end_position): Doc fix.
5397 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5399 2012-09-22 Chong Yidong <cyd@gnu.org>
5401 * dispextern.h (struct image_type): Add new slot, storing a type
5402 initialization function.
5404 * image.c (define_image_type): Call the image initializer function
5405 if it is defined. Arguments and return value changed.
5406 (valid_image_p, make_image): Callers changed.
5407 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5408 (gif_type, imagemagick_type, svg_type, gs_type):
5409 Add initialization functions.
5410 (Finit_image_library): Call lookup_image_type.
5411 (CHECK_LIB_AVAILABLE): Macro deleted.
5412 (lookup_image_type): Call define_image_type here, rather than via
5413 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5414 (syms_of_image): Move define_image_type calls for xbm_type and
5415 pbm_type to lookup_image_type.
5417 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5419 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5420 'idle_timers' from here ...
5421 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5422 lists, to avoid infloops when the timer does something stupid,
5423 like reinvoke itself with the same or smaller time-out.
5426 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5428 * window.c (Fsplit_window_internal): Handle only Qt value of
5429 Vwindow_combination_limit separately.
5430 (Qtemp_buffer_resize): New symbol.
5431 (Vwindow_combination_limit): New default value.
5434 2012-09-22 Eli Zaretskii <eliz@gnu.org>

5437 the new overlay string. (Bug#10159)
5439 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5441 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5442 or that fprintf is async-signal-safe. POSIX doesn't require
5445 2012-09-22 Chong Yidong <cyd@gnu.org>
5447 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5450 2012-09-22 Kenichi Handa <handa@gnu.org>
5452 * composite.c (composition_reseat_it): Handle the case that a
5453 grapheme cluster is not covered by a single font (Bug#12352).
5455 2012-09-21 Chong Yidong <cyd@gnu.org>
5457 * image.c (define_image_type): Avoid adding duplicate types to
5458 image_types (Bug#12463). Suggested by Jörg Walter.
5460 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5462 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5463 (print_load_command_name): Add case LC_DATA_IN_CODE.
5464 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

5468 * eval.c (Frun_hook_with_args_until_success)
5469 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5471 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5473 * fileio.c (Ffile_selinux_context): Only call freecon when
5474 lgetfilecon succeeded.
5475 (Fset_file_selinux_context): Likewise. (Bug#12444)
5477 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5479 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5480 reordering, locate the cursor by calling set_cursor_from_row; if
5481 that fails, clear the desired glyph matrix before returning a
5482 failure indication to the caller. Fixes leaving garbled display
5483 when fast scrolling with a down-key. (Bug#12403)
5484 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5485 scrolling through multibyte text.
5487 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5489 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5490 calling mark_vectorlike since that's the one that marks the window.
5491 (mark_discard_killed_buffers): Mark the final cdr.
5492 * window.h (struct window): Move prev/next_buffers to the
5493 non-standard fields.
5494 * window.c (make_window): Initialize prev/next_buffers manually.
5496 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5498 Omit unused arg EXPECTED from socket hooks.
5499 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5500 * nsterm.m (ns_term_init):
5501 * termhooks.h (struct terminal.read_socket_hook):

5504 * xterm.c (XTread_socket):
5505 Omit unused arg EXPECTED. All callers changed.
5506 (store_user_signal_events): Return void, not int, since callers no
5507 longer care about the return value. All uses changed.
5509 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5511 * w32gui.h (XParseGeometry): Do not declare.
5513 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5515 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5516 Ignore 'expected'. See Eli Zaretskii in
5517 <http://bugs.gnu.org/12471#8> (last line).
5519 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5520 (XParseGeometry): Now static. Substitute extremal values for
5521 values that are out of range.
5523 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5525 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5527 * nsfns.m (XParseGeometry): Remove.
5528 (Fx_create_frame): Call x_set_offset to correctly interpret
5529 top_pos in geometry.
5531 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5532 (Fx_parse_geometry): If there is a space in string, call
5533 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5535 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5537 * search.c (scan_buffer): Use character positions in calls to
5538 region_cache_forward and region_cache_backward, not byte
5539 positions. (Bug#12196)
5541 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5542 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5544 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5545 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5546 emacs_blocked_malloc, now deleted.
5548 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5550 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5551 The workaround was for improving performance on Solaris 2.4, but
5552 is getting in the way now. Emacs will still work if someone is
5553 still running Solaris 2.4 in a museum somewhere; Sun dropped
5554 support for Solaris 2.4 in 2003.
5555 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5556 * process.c (create_process) [HAVE_WORKING_VFORK]:
5557 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5558 since Emacs no longer uses vfork on that platform.
5560 2012-09-17 Glenn Morris <rgm@gnu.org>
5562 * emacs.c: Use COPYRIGHT.
5564 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5566 Remove configure's --without-sync-input option (Bug#12450).
5567 When auditing signal-handling in preparation for cleaning it up,
5568 I found that SYNC_INPUT has race conditions and would be a real
5569 pain to fix. Since it's an undocumented and deprecated
5570 configure-time option, now seems like a good time to remove it.
5571 Also see <http://bugs.gnu.org/11080#16>.
5572 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5573 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5574 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5575 (malloc_hysteresis):
5576 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5577 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5578 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5579 (dont_register_blocks, bytes_used_when_reconsidered)
5580 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5581 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5582 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5583 Remove. All uses removed.
5584 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5585 implementation, one that depends on whether the new macro
5586 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5588 * atimer.c (run_timers, handle_alarm_signal):
5589 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5590 (handle_async_input, process_pending_signals)
5591 (handle_input_available_signal, init_keyboard):
5592 * nsterm.m (ns_read_socket):
5593 * process.c (wait_reading_process_output):
5594 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5595 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5597 * xterm.c (XTread_socket):
5599 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5600 * eval.c (handling_signal): Remove. All uses removed.
5601 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5602 All uses replaced with the SYNC_INPUT version.
5603 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5605 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5608 * font.c (Ffont_shape_gstring): Remove unused local.
5610 2012-09-16 Glenn Morris <rgm@gnu.org>
5612 * Makefile.in (clean): No longer run nextstep's clean.
5614 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5616 (ns-app): Move here from ns.mk, and simplify.
5617 (clean): Simplify nextstep entry.
5618 * ns.mk: Remove file.
5620 2012-09-17 Kenichi Handa <handa@gnu.org>
5622 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5623 not covert the last few charactes.
5625 2012-09-16 Kenichi Handa <handa@gnu.org>
5627 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5628 here, but just check the validity of glyphs in the glyph-string.
5630 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5632 * window.c (Fwindow_parameter, Fset_window_parameter):
5633 Accept any window as argument (Bug#12452).
5635 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5637 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5638 to ns_term_init to avoid memory leak.
5640 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5641 explicit retain/release.
5642 (ns_term_init): Only allow one display. Initialize outerpool and
5645 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5647 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5648 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5649 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5650 the Microsoft problem in a different way, by altering ../nt/config.nt.
5652 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5667 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5668 by lisp.h. This completes removal of setjmp.h inclusion
5669 erroneously announced in the previous commit. (Bug#12446)
5671 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5674 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5675 not defined as a macro. The latter happens on MS-Windows.
5678 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5680 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5681 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5682 Some instances of '#include <setjmp.h>' removed, if the
5683 only reason for the instance was because "lisp.h" was included.
5684 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5685 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5686 and _longjmp with the new symbols. Emacs already uses _setjmp if
5687 available, so this change affects only POSIXish hosts that have
5688 sigsetjmp but not _setjmp, such as some versions of Solaris and
5689 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5690 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5691 (png_load_body) [HAVE_PNG]:
5692 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5693 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5694 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5695 since PNG requires jmp_buf. This is the only exception to the
5696 general rule that we now use sys_setjmp and sys_longjmp.
5697 This exception is OK since this code does not change the signal
5698 mask or longjmp out of a signal handler.
5700 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5702 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5703 Include "syssignal.h", for 'main_thread'.
5705 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5707 Avoid out-of-range marker position (Bug#12426).
5708 * insdel.c (replace_range, replace_range_2):
5709 Adjust markers before overlays, as suggested by comments.
5710 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5711 Remove redundant check before calling offset_intervals.
5713 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5715 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5716 current buffer (Bug#12387).
5718 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5720 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5722 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5724 Use a more backwards-compatible timer format (Bug#12430).
5725 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5726 vector element, not from the 4th, since PSECS is now at the end.
5727 (Fcurrent_idle_time): Doc fix.
5729 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5731 Function to mark objects and remove killed buffers at once.
5732 * alloc.c (discard_killed_buffers): Rename to ...
5733 (mark_discard_killed buffers) ... new name. Add marking
5734 of remaining objects. Fix comment. Adjust users.
5735 (mark_object): Do not touch frame buffer lists here.
5736 * frame.c (delete_frame): Reset frame buffer lists here.
5738 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5740 Better workaround for GNOME bug when --enable-gcc-warnings.
5741 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5742 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5743 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5745 Simplify SIGIO usage (Bug#12408).
5746 The code that dealt with SIGIO was crufty and confusing, e.g., it
5747 played tricks like "#undef SIGIO" but these tricks were not used
5748 consistently. Simplify mostly by not #undeffing standard symbols,
5749 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5750 or not as we please) rather than "defined SIGIO" (standard symbol
5751 that we probably shouldn't #undef).
5752 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5753 Modules that need it can include it.
5754 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5755 * dispextern.h (ignore_sigio): New decl.
5756 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5757 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5758 * emacs.c (shut_down_emacs):
5759 * keyboard.c (kbd_buffer_store_event_hold):
5760 Use ignore_sigio rather than invoking 'signal' directly.
5761 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5763 (FIONREAD, SIGIO): Do not #undef.
5764 (tty_read_avail_input): Use #error rather than a syntax error.
5765 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5766 for I_PIPE, used by SETUP_SLAVE_PTY.
5767 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5768 * sysdep.c (croak): Remove; no longer needed. This bit of
5769 temporary code, with Fred N. Fish's comment that it's temporary,
5770 has been in Emacs since at least 1992!
5771 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5772 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5773 * syssignal.h (croak): Remove decl.
5774 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5775 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5776 now that we're termios-only.
5777 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5778 * term.c (dissociate_if_controlling_tty): Use #error rather than
5781 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5782 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5783 to work around GNOME bug 683906.
5784 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5785 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5786 This works around GCC bug 54561.
5788 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5790 More fixes for 'volatile' and setjmp/longjmp.
5791 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5792 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5793 (png_load_body) [HAVE_PNG]:
5794 (jpeg_load_body) [HAVE_JPEG]:
5795 New function, with most of the old parent function's body.
5796 (png_load) [HAVE_PNG]:
5797 (jpeg_load) [HAVE_JPEG]:
5798 Invoke the new function, to avoid longjmp munging our locals.
5799 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5800 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5801 longjmp is passed 2, as the C standard doesn't guarantee this.
5802 Instead, store the failure code into mgr->failure_code.
5804 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5806 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5807 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5808 (syms_of_keyboard): Remove support for unread-command-char.
5810 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5812 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5813 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5814 violation. (Bug#12426)
5816 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5818 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5820 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5822 * eval.c: Add `inhibit-debugger'.
5823 (Qinhibit_debugger): New symbol.
5824 (call_debugger): Bind it instead of Qdebug_on_error.
5825 (maybe_call_debugger): Test Vinhibit_debugger.
5826 (syms_of_eval): Define inhibit-debugger.
5827 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5828 (syms_of_xdisp): Remove inhibit-debug-on-message.
5830 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5832 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5833 If a nonvolatile local variable is written before a _longjmp to
5834 the frame containing the variable, and is read after the _longjmp,
5835 the value read is indeterminate. Some local variables of type
5836 'struct handler' and 'struct catchtag' are used in this way, so
5837 mark each of their slots as volatile if the slot can be set before
5838 _longjmp and read afterwards.
5839 * lisp.h (struct handler): var and chosen_clause are now volatile.
5840 (struct catchtag): val, next, and pdlcount are now volatile.
5842 * bidi.c (bidi_push_it, bidi_pop_it):
5843 * fns.c (copy_hash_table):
5844 * image.c (define_image_type):
5845 * keyboard.c (kbd_buffer_store_event_hold):
5846 * process.c (Fprocess_send_eof):
5847 * xfaces.c (x_create_gc) [HAVE_NS]:
5848 * xgselect.c (xg_select):
5849 Prefer assignment to memcpy when either will do.
5851 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5852 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5853 time an item is removed. No need to mark this function 'inline';
5854 the compiler knows better than we do.
5856 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5858 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5859 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5860 to change_frame_size (Bug#12388).
5861 (windowDidResize:): Pass YES to updateFrameSize.
5863 * nsterm.h: Add delay parameter to updateFrameSize.
5865 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5867 Discard killed buffers from deleted window and frame objects.
5868 This reduces an amount of references to killed buffers and
5869 helps GC to reclaim them faster.
5870 * alloc.c (discard_killed_buffers): New function.
5871 (mark_object): Use it for deleted windows and frames.
5872 (mark_object): If symbol's value is set up for a killed buffer
5873 or deleted frame, restore its global binding.
5874 * data.c (swap_in_global_binding): Add GC notice.
5875 (swap_in_symval_forwarding): Use convenient set_blv_where.
5876 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5877 * window.h: ... to here.
5879 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5881 Convenient macro to check whether the buffer is live.
5882 * buffer.h (BUFFER_LIVE_P): New macro.
5883 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5884 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5886 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5888 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5889 composition cases (Bug#12364).
5891 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5892 overhang of succeeding glyphs overlapping box cursor.
5894 * w32term.c (x_draw_glyph_string): Likewise.
5896 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5898 Simplify, document, and port floating-point (Bug#12381).
5899 The porting part of this patch fixes bugs on non-IEEE platforms
5900 with frexp, ldexp, logb.
5901 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5903 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5904 support, by removing commented-out code and briefly listing the
5905 C89 functions excluded. The commented-out stuff was confusing
5906 maintenance, e.g., we thought we needed cbrt but it was commented out.
5907 (logb): Remove decl; no longer needed.
5908 (isfinite): New macro, if not already supplied.
5909 (isnan): Don't replace any existing macro.
5910 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5911 are present on all C89 platforms.
5912 (Ffrexp): Do not special-case zero, as frexp does the right thing
5914 (Flogb): Do not use logb, as it doesn't have the desired meaning
5915 on hosts that use non-base-2 floating point. Instead, stick with
5916 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5917 frexp, to avoid getting an unspecified result.
5919 * xdisp.c (Qinhibit_debug_on_message): Now static.
5921 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5923 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5924 NSBezierPath (Bug#12131).
5926 2012-09-10 Chong Yidong <cyd@gnu.org>
5928 * fns.c (Fdelq, Fdelete): Doc fix.
5930 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5932 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5933 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5935 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5937 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5938 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5941 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5943 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5944 left fringe if the window has a left margin. This avoids leaving
5945 traces of the cursor because its leftmost pixel is not drawn over.
5947 * dispnew.c (update_window_line): When the left margin area of a
5948 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5949 that screen line. (Bug#12277)
5951 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5953 Assume C89 or later for math functions (Bug#12381).
5954 This simplifies the code, and makes it a bit smaller and faster,
5955 and (most important) makes it easier to clean up signal handling
5956 since we can stop worring about floating-point exceptions in
5957 library code. That was a problem before C89, but the problem
5958 went away many years ago on all practical Emacs targets.
5959 * data.c, image.c, lread.c, print.c:
5960 Don't include <math.h>; no longer needed.
5961 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5962 might be autoconfigured, as that never happens.
5964 * doprnt.c (DBL_MAX_10_EXP):
5965 * print.c (DBL_DIG):
5966 Remove. C89 or later always defines these.
5967 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5968 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5969 (arith_error, domain_error, domain_error2):
5970 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5971 no longer needed -- we simply return what C returns. All uses removed.
5972 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5974 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5975 Remove. All uses expanded, as these macros are no longer used
5976 more than once and are now more trouble than they're worth.
5977 (Ftan): Use tan, not sin / cos.
5978 (Flogb): Assume C89 frexp.
5979 (fmod_float): Assume C89 fmod.
5980 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5981 (init_floatfns): Remove. All uses removed.
5983 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5985 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5986 compositeToPoint for OSX < 10.6 (Bug#12390).
5988 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5990 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5991 This produces more-accurate results.
5993 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5995 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5996 changes (Bug#12088).
5998 2012-09-08 Chong Yidong <cyd@gnu.org>
6000 * syntax.c (Fstring_to_syntax): Doc fix.
6002 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6004 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6005 in the internal border.
6006 (x_set_window_size): Remove static variables and their usage.
6007 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6008 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6009 Remove fringe/internal border adjustment (Bug#11052).
6010 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6011 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6012 (ns_fix_rect_ibw): Remove.
6013 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6014 (ns_dumpglyphs_box_or_relief): Ditto.
6015 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6017 (ns_dumpglyphs_image): Ditto.
6018 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6020 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6021 their usage. Add fringe_extended_p and its use as in other terms.
6022 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6023 scroll bar was removed.
6024 (updateFrameSize): New function.
6025 (windowDidResize): Move code to updateFrameSize and call it.
6027 * nsterm.h (EmacsView): Add updateFrameSize.
6029 2012-09-07 Chong Yidong <cyd@gnu.org>
6031 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6033 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6035 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6037 More signal-handler cleanup (Bug#12327).
6038 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6039 Problem introduced when merging patches. Noted by Eli Zaretskii in
6040 <http://bugs.gnu.org/12327#67>.
6041 * floatfns.c: Comment fix.
6042 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6043 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6044 and anyway the declaration is harmless even if SIGDANGER is not defined.
6045 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6046 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6047 source files not surprisingly expected syssignal.h to define, or
6048 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6049 Include <sys/ioctl.h>, for FIONREAD.
6050 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6051 This eliminates a problem whereby other files mysteriously had
6052 to include "syssignal.h" before including "systty.h" if they
6053 wanted to use "#ifdef SIGIO".
6055 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6057 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6059 * w32.c (sigemptyset): Empty the set.
6060 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6062 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6064 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6066 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6067 (mark_object): Likewise for frame objects.
6069 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6071 * syssignal.h (handle_on_main_thread): Always declare,
6072 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6073 This ports to platforms without HAVE_PTHREAD.
6075 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6077 Signal-handler cleanup (Bug#12327).
6078 Emacs's signal handlers were written in the old 4.2BSD style with
6079 sigblock and sigmask and so forth, and this led to some
6080 inefficiencies and confusion. Rewrite these to use
6081 pthread_sigmask etc. without copying signal sets around. Also,
6082 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6083 'signal', and instead use functions that do not attempt to take
6084 over the system name space. This patch causes Emacs's text
6085 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6086 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6087 Do not include <signal.h> or "syssignal.h", as these
6088 modules do not use signals.
6089 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6090 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6091 Do not include <signal.h>, as "syssignal.h" does that for us now.
6092 * atimer.c (sigmask_atimers): New function.
6093 (block_atimers, unblock_atimers): New functions,
6094 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6096 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6097 no longer needed here.
6098 * emacs.c (main): Inspect existing signal handler with sigaction,
6099 so that there's no need to block and unblock SIGHUP.
6100 * sysdep.c (struct save_signal): New member 'action', replacing
6101 old member 'handler'.
6102 (save_signal_handlers, restore_signal_handlers):
6103 Use sigaction instead of 'signal' to save and restore.
6104 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6105 New function. All users of 'signal' modified to use set_sighandler
6106 if they're writeonly, and to use sys_signal if they're read+write.
6107 (emacs_sigaction_init, forwarded_signal): New functions.
6108 (sys_signal): Remove. All uses replaced by calls to sigaction
6109 and emacs_sigaction_init, or by direct calls to 'signal'.
6110 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6111 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6112 all uses replaced by pthread_sigmask etc. calls.
6113 * syssignal.h: Include <signal.h>.
6114 (emacs_sigaction_init, forwarded_signal): New decls.
6115 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6116 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6117 (sigmask, sys_sigmask): Remove; no longer needed.
6118 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6119 (sigblock, sigunblock, sigfree):
6120 (sigsetmask) [!defined sigsetmask]:
6121 Remove. All uses replaced by pthread_sigmask.
6122 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6123 no longer need to be replaced, and its typical old uses
6124 are now done via emacs_sigaction_init and sigaction.
6125 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6126 (sys_sigdel): Remove; unused.
6127 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6129 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6131 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6132 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6134 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6136 Explicitly mark buffer_defaults and buffer_local_symbols.
6137 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6138 mark_local_symbols here.
6139 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6140 since special buffers aren't marked here any more.
6141 (allocate_buffer): Chain new buffer with all_buffers here...
6142 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6144 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6145 (syms_of_buffer): Remove staticpro of the above.
6146 (init_buffer_once): Set names for buffer_defaults and
6147 buffer_local_symbols.
6149 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6151 Use bool for booleans in font-related modules.
6152 * font.c (font_intern_prop, font_style_to_value)
6153 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6154 (generate_otf_features, font_check_otf_features, font_check_otf)
6155 (font_match_p, font_list_entities, font_at):
6156 * fontset.c (fontset_id_valid_p, reorder_font_vector
6157 (fontset_find_font, Fset_fontset_font)
6158 (face_suitable_for_char_p) [0]:
6159 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6160 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6161 (m17n_flt_initialized, ftfont_shape_by_flt):
6162 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6163 * nsfont.m (nsfont_draw):
6164 * w32font.c (w32font_draw):
6165 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6166 Use bool for booleans.
6167 * font.h: Adjust to above API changes.
6168 (struct font, struct font_driver, struct font_driver_list):
6169 Use bool for booleans.
6170 (struct font): Remove useless member encoding_type.
6172 * fontset.c, xftfont.c: Omit unnecessary static decls.
6174 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6176 * alloc.c (mark_object): Revert window marking code
6177 since it's unsafe for the Fset_window_configuration.
6179 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6181 Fix race conditions with signal handlers and errno (Bug#12327).
6182 Be more systematic about preserving errno whenever a signal
6183 handler returns, even if it's not in the main thread. Do this by
6184 renaming signal handlers to distinguish between signal delivery
6185 and signal handling. All uses changed.
6186 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6187 * data.c (deliver_arith_signal): Rename from arith_error.
6188 * dispnew.c (deliver_window_change_signal): Rename from
6189 window_change_signal.
6190 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6191 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6192 * keyboard.c (deliver_input_available_signal): Rename from
6193 input_available_signal.
6194 (deliver_user_signal): Rename from handle_user_signal.
6195 (deliver_interrupt_signal): Rename from interrupt_signal.
6196 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6197 (deliver_child_signal): Rename from sigchld_handler.
6198 * atimer.c (handle_alarm_signal):
6199 * data.c (handle_arith_signal):
6200 * dispnew.c (handle_window_change_signal):
6201 * emacs.c (handle_fatal_signal, handle_danger_signal):
6202 * keyboard.c (handle_input_available_signal):
6203 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6204 * process.c (handle_pipe_signal, handle_child_signal):
6205 New functions, with the actual signal-handling code taken from the
6206 original respective signal handlers, sans the sporadic attempts to
6207 preserve errno, since that's now done by handle_on_main_thread.
6208 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6209 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6210 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6212 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6213 Move initialization of main_thread to sysdep.c's init_signals.
6214 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6215 our usage, and simplifies the mainline code.
6216 (record_child_status_change): New static function, as a helper
6217 for handle_child_signal, and with most of the old child handler's
6219 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6220 (handle_child_signal): Use the above.
6221 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6222 Moved here from emacs.c.
6223 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6224 code moved here from emacs.c's main function.
6225 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6226 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6227 This lets callers save and restore errno properly.
6229 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6231 Remove redundant or unused things here and there.
6232 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6233 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6234 * editfns.c (Fcompare_buffer_substrings): Likewise.
6235 * frame.h (struct terminal, struct font_driver_list):
6236 Remove redundant declarations.
6237 * window.h (Qleft, Qright): Likewise.
6239 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6241 Do not mark objects from deleted buffers, windows and frames.
6242 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6243 (mark_object): Likewise for windows and frames.
6245 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6247 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6248 buffer_defaults and buffer_local_symbols as valid objects.
6249 Return special value to denote them.
6251 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6253 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6254 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6255 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6256 (file_name_absolute_p, Fsubstitute_in_file_name):
6257 (check_executable, check_writable, Ffile_accessible_directory_p)
6258 (Fset_file_selinux_context, Fdefault_file_modes)
6259 (Finsert_file_contents, choose_write_coding_system)
6260 (Fwrite_region, build_annotations, a_write, e_write)
6262 * filelock.c (boot_time_initialized, get_boot_time)
6263 (get_boot_time_1, lock_file_1, within_one_second):
6264 * floatfns.c (in_float):
6265 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6266 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6267 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6268 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6269 * window.c (compare_window_configurations):
6270 Use bool for booleans.
6271 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6272 (Fdefault_file_modes): Now mode_t, not int, for modes.
6273 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6274 (internal_delete_file): Now returns void, not a (boolean) int,
6275 since nobody was looking at the return value.
6276 * lisp.h, window.h: Adjust to above API changes.
6278 * xdisp.c (set_message): Simplify and reindent last change.
6280 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6282 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6284 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6286 * eval.c (call_debugger): Make the function non-static so that we
6287 can call it from set_message.
6289 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6290 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6292 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6294 Give more-useful info on a fatal error (Bug#12328).
6295 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6296 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6297 of doing the work ourselves.
6298 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6299 do most of the work.
6300 (fatal_error_backtrace): New function, taken from the guts
6301 of the old fatal_error_signal, but with a new option to output
6303 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6304 info about the signal than just its number.
6305 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6306 * sysdep.c: Include <execinfo.h>
6307 (emacs_backtrace): New function, taken partly from the previous
6308 code of the 'die' function.
6309 (emacs_abort): Call fatal_error_backtrace rather than abort.
6311 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6313 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6314 eager (load-time) macro-expansion.
6315 * lisp.mk (lisp): Add macroexp.
6317 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6319 Simplify redefinition of 'abort' (Bug#12316).
6320 Do not try to redefine the 'abort' function. Instead, redo
6321 the code so that it calls 'emacs_abort' rather than 'abort'.
6322 This removes the need for the NO_ABORT configure-time macro
6323 and makes it easier to change the abort code to do a backtrace.
6324 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6325 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6326 Remove; sysdep.c's emacs_abort now takes its place.
6327 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6328 'abort' changed to use 'emacs_abort'.
6329 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6330 (abort) [!defined abort]: Rename to ...
6331 (emacs_abort): ... new name.
6332 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6333 the place of the old 'abort' in emacs.c.
6334 * w32.c, w32fns.c (abort): Do not #undef.
6335 * w32.c (emacs_abort): Rename from w32_abort.
6337 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6339 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6340 offsets[j].dv, since the y axis of the screen coordinates points
6341 down, while the y axis of the font definition coordinates points
6342 up. This fixes display of Arabic diacritics such as KASRA and
6343 KASRATAN. (Bug#11860)
6345 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6347 Be more systematic about _setjmp vs setjmp.
6348 * alloc.c (test_setjmp, mark_stack):
6349 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6350 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6351 (png_load, my_error_exit, jpeg_load):
6352 * process.c (send_process_trap, send_process):
6353 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6354 The underscored versions are up to 30x faster on some hosts.
6355 Formerly, the code used setjmp+longjmp sometimes and
6356 _setjmp+_longjmp at other times, with no particular reason to
6357 prefer setjmp+longjmp.
6359 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6361 Fix minor problem found by static checking.
6362 * buffer.c (Fdelete_all_overlays): Return nil.
6364 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6366 * buffer.c (Fdelete_all_overlays): New function.
6368 2012-09-03 Chong Yidong <cyd@gnu.org>
6370 * gtkutil.c: Add extern decl for Qxft.
6372 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6374 * emacs.c, eval.c: Use bool for boolean.
6375 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6376 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6377 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6378 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6379 (main, decode_env_path, Fdaemon_initialized):
6380 * eval.c (call_debugger, Finteractive_p, interactive_p):
6381 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6382 (maybe_call_debugger, Fbacktrace):
6383 * process.c (read_process_output, exec_sentinel):
6384 Use bool for booleans.
6385 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6386 All callers changed.
6387 * eval.c (interactive_p): Omit always-true boolean argument
6388 EXCLUDE_SUBRS_P. All callers changed.
6389 * dispextern.h, lisp.h: Reflect above API changes.

6398 REDISPLAYING_P when unwinding, instead of saving its previous,
6399 always-false value and then restoring it.
6401 Clean up some extern decls.
6402 Mostly, this hoists extern decls out of .c files and into .h files.
6403 That way, we're more likely to catch errors if the interfaces change.

6489 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6490 more than one grapheme cluster passed to the shaper: compute the
6491 offset adjustment values separately for each cluster. (Bug#11860)
6493 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6494 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6495 about implicit conversions from integer to pointer.
6497 2012-09-01 Daniel Colascione <dancol@dancol.org>
6499 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

6553 window system declarations.
6555 * frame.h: Move common functions here: set_frame_menubar,
6556 x_set_window_size, x_sync, x_get_focus_frame,
6557 x_set_mouse_position, x_set_mouse_pixel_position,
6558 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6644 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6645 Add window_closed and button_values. Add void as return value for
6646 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6647 Add process_dialog as new member.

6837 (string_escape_byte8):
6838 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6839 (load_charset_map_from_file, map_charset_chars)
6840 (Fdefine_charset_internal, define_charset_internal)
6841 (Fdeclare_equiv_charset, find_charsets_in_text)
6842 (Ffind_charset_region, char_charset, Fiso_charset):
6843 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6844 (sub_char_table_set, sub_char_table_set_range)
6845 (char_table_set_range, optimize_sub_char_table)
6846 (map_sub_char_table):
6847 Use bool for boolean.
6848 * character.c (str_to_unibyte): Omit last boolean argument; it was
6849 always 0. All callers changed.
6850 * character.h, charset.h: Adjust to match previous changes.
6851 * character.h (char_printable_p): Remove decl of nonexistent function.
6852 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6853 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6854 are all boolean, so make them single-bit bitfields.
6856 * lisp.h (ASET): Remove attempt to detect side effects.
6857 It was meant to be temporary and it often doesn't work,
6858 because when IDX has side effects the behavior of IDX==IDX
6859 is undefined. See Stefan Monnier in
6860 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6862 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6864 * lisp.h (functionp): New function (extracted from Ffunctionp).
6865 (FUNCTIONP): Use it.
6866 * eval.c (Ffunctionp): Use it.
6868 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6870 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6871 as that's faster and simpler than static storage. Don't bother
6872 with the g_main_context_query overhead if g_main_context_pending
6873 says no events are pending.
6874 (gfds, gfds_size): Remove these static vars.
6875 (xgselect_initialize): Remove; no longer needed.
6876 All uses and decls removed.
6878 * emacs.c (fatal_error_signal_hook): Remove.
6879 All uses removed. This leftover from old code was always 0.
6881 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6882 * casefiddle.c (casify_object, casify_region):
6883 * casetab.c (set_case_table):
6884 * category.c, category.h (word_boundary_p):
6885 * category.h (CHAR_HAS_CATEGORY):
6886 Use bool for booleans, instead of int.
6888 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6890 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6892 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6894 On assertion failure, print backtrace if available.
6895 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6896 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6897 * Makefile.in (LIB_EXECINFO): New macro.
6900 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6901 * bytecode.c (exec_byte_code):
6902 * callint.c (check_mark, Fcall_interactively):
6903 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6904 (getenv_internal, sync_process_alive, call_process_exited):
6905 * lisp.h (USE_SAFE_ALLOCA):
6906 Use bool for booleans, instead of int.
6907 * lisp.h, process.h: Adjust prototypes to match above changes.
6908 * callint.c (Fcall_interactively): Don't assume the mark's
6909 offset fits in 'int'.
6911 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6913 * buffer.c, buffer.h: Use bool for boolean.
6914 * buffer.c (reset_buffer_local_variables)
6915 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6916 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6917 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6918 (overlay_touches_p, overlay_strings, Foverlay_put)
6919 (report_overlay_modification, call_overlay_mod_hooks):
6920 (mmap_enlarge, mmap_set_vars):
6921 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6922 Use bool for booleans, instead of int.
6923 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6924 since the 1-or-0 return value is always ignored anyway.
6925 (mmap_initialized_p):
6926 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6927 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6929 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6931 * bidi.c: Use bool for boolean.
6932 This is a bit more readable, and makes the text segment of bidi.o
6933 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6934 Presumably it's faster too.
6935 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6937 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6938 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6939 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6940 (bidi_explicit_dir_char, bidi_level_of_next_char)
6941 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6942 Use bool for booleans, instead of int.
6943 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6944 (bidi_unshelve_cache): Adjust decls to match code.
6946 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6948 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6951 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6953 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6954 * atimer.h: Include <stdbool.h>.
6956 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6958 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6959 compile time tests instead of run time tests on systems that do
6961 (FRAME_MAC_P): Remove leftover from deleted code.
6962 * frame.c (syms_of_frame): Remove leftover from deleted code.
6964 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6966 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6968 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6970 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6971 Otherwise, the compiler complains about (A?B:C) where B is void
6972 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6973 (fontset_add): Return void, for FONTSET_ADD.
6975 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6977 * alloc.c: Use bool for booleans.
6978 (gc_in_progress, abort_on_gc)
6979 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6980 (dont_register_blocks) [GC_MALLOC_CHECK]:
6981 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6982 (check_string_bytes, make_specified_string, memory_full)
6983 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6984 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6985 (mark_stack, valid_pointer_p, make_pure_string)
6986 (Fgarbage_collect, survives_gc_p, gc_sweep):
6987 Use bool for booleans, instead of int.
6988 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6989 Remove unused local.
6990 * alloc.c (PURE_POINTER_P):
6991 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6992 * editfns.c (Fformat):
6993 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6995 * fns.c (sweep_weak_table):
6996 * lisp.h (suppress_checking, push_message, survives_gc_p)
6997 (make_pure_string, gc_in_progress, abort_on_gc):
6998 * lread.c (readchar, read1):
6999 * print.c (Fprin1_to_string):
7000 * xdisp.c (push_message):
7001 Use bool for booleans affected directly or indirectly by
7004 Make recently-introduced setters macros.
7005 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7006 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7007 (set_fontset_default, set_fontset_fallback): Rename from their
7008 upper-case counterparts, and make them functions rather than macros.
7009 This is more consistent with the other recently-introduced setters.
7010 These don't need to be inline, since they're local.
7012 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7014 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7015 the loop (Bug#12247).
7017 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7019 * lisp.h (vcopy): Use memcpy rather than our own loop.
7020 This fixes a performance regression introduced by the recent
7021 addition of vcopy. This means 'vcopy' will need to be modified
7022 for a copying collector, but that's OK. Also, tighten the
7023 checking in the assertion.
7025 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7027 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7028 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7029 non-base glyph for the width of the base character, according to
7030 what x_draw_composite_glyph_string_foreground expects.
7031 Generate WADJUST value according to composition_gstring_width's
7032 expectations, to produce correct width of the composed character.
7033 Reverse the sign of the DU offset produced by ScriptPlace.
7035 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7037 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7039 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7041 Avoid direct writes to contents member of struct Lisp_Vector.
7042 * lisp.h (vcopy): New function to copy data into vector.
7043 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7044 * fns.c (Ffillarray): Use ASET.
7045 * keyboard.c (timer_check_2): Use AREF and ASET.
7046 (append_tool_bar_item, Frecent_keys): Use vcopy.
7047 * lread.c (read_vector): Use ASET.
7048 * msdos.c (Frecent_doskeys): Use vcopy.
7049 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7050 (Finternal_merge_in_global_face): Use ASET and vcopy.
7051 * xfont.c (xfont_list_pattern): Likewise.
7053 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7055 * window.c (Fwindow_point): For the selected window always return
7056 the position of its buffer's point.
7057 (Fset_window_point): For the selected window always go in its
7058 buffer to the specified position.
7060 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7062 Setter macros for fontsets.
7063 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7064 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7065 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7068 2012-08-20 Glenn Morris <rgm@gnu.org>
7070 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7071 Don't assume that `ln -f' works.
7073 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7075 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7076 and later about non-assignments with no effect. See discussion at
7077 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7080 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7082 Inline setter functions for Lisp_Objects slots of struct specbinding.
7083 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7086 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7088 * window.c (select_window): Always make selected window's buffer
7091 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7093 Use AREF and ASET for docstrings of category tables.
7094 * category.h (CATEGORY_DOCSTRING): Use AREF.
7095 (SET_CATEGORY_DOCSTRING): Use ASET.
7096 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7098 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7100 Inline setter functions for hash table members.
7101 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7102 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7103 (set_hash_key_and_value, set_hash_index, set_hash_next)
7104 (set_hash_hash): New functions.
7105 * charset.c, fns.c: Adjust users.
7107 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7109 Inline getter and setter functions for per-buffer values.
7110 * buffer.h (per_buffer_default, set_per_buffer_default)
7111 (per_buffer_value, set_per_buffer_value): New functions.
7112 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7113 * buffer.c, data.c: Adjust users.
7115 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7117 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7119 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7121 Rely on <config.h> + <unistd.h> to declare 'environ',
7122 as gnulib does this if the system doesn't.
7123 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7124 Remove declaration. MS-Windows declares it on stdlib.h which is
7125 included by conf_post.h.
7126 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7127 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7128 * vm-limit.c: Include <unistd.h>, for 'environ'.
7130 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7131 (start_of_data): Remove decl; mem-limits.h provides it.
7133 * xdisp.c (handle_invisible_prop): Make it a bit faster
7134 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7136 2012-08-19 Chong Yidong <cyd@gnu.org>
7138 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7141 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7143 * .gdbinit: Use call instead of set when calling a function in the
7146 * data.c (set_internal): Don't use set_blv_found.
7147 (Fkill_local_variable): Likewise.
7149 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7151 * nsfont.m (ns_ascii_average_width): Ensure the string
7152 ascii_printable is initialized with a null-terminated character
7153 array. Otherwise, it can contain undesired extra characters.
7155 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7157 port new setting code to Sun C 5.8 2005/10/13
7158 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7159 Return void, not Lisp_Object. Otherwise, the compiler
7160 complains about (A?B:C) where B is void and C is Lisp_Object
7161 when compiling CHAR_TABLE_SET, due to the recent change to
7162 the API of sub_char_table_set_contents.
7164 2012-08-18 Chong Yidong <cyd@gnu.org>
7166 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7167 for the string case (Bug#3874).
7169 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7171 * buffer.h (BSET): Remove (Bug#12215).
7172 Replace all uses with calls to new setter functions.

7241 New setter functions.
7243 * termhooks.h (TSET): Remove (Bug#12215).
7244 Replace all uses with calls to new setter functions.
7245 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7246 (TERMHOOKS_INLINE): New macro.
7247 (tset_charset_list, tset_selection_alist): New setter functions.
7248 * terminal.c (TERMHOOKS_INLINE):
7249 Define to EXTERN_INLINE, so that the corresponding functions
7250 are compiled into code.
7251 (tset_param_alist): New setter function.
7253 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
7255 * keyboard.h (KSET): Remove (Bug#12215).

7999 value of EMACSLOADPATH, as it is no longer needed.
8000 (check_windows_init_file): Now external, not static.
8001 Use Vload_path as is, without adding anything, as this function is now
8002 called when Vload_path is already set up.

8006 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8051 * alloc.c (record_xmalloc): New function.
8052 * lisp.h (record_xmalloc): New decl.
8053 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8054 more like a function. This is because the pointer cast is not
8055 needed. All uses changed.
8056 * print.c (print_string, print_error_message): Avoid length recalc.
8058 Improve fix for macroexp crash with debugging (Bug#12118).
8059 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8060 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8061 not supposed to be invoked from the garbage collector.

8063 (gc_aset): New function, which is like ASET but can be
8064 used in the garbage collector.

8093 with addition of handling of symlinks and support for 'lstat'.
8094 If possible, get file's attributes and security information by
8095 handle, not by name. Produce S_IFLNK bit for symlinks, when
8096 called from 'lstat'.
8097 (stat, lstat): New functions, call 'stat_worker'.
8098 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8099 symlinks when the underlying filesystem supports them.
8101 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8103 Fix macroexp crash on Windows with debugging (Bug#12118).
8104 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8105 checking subscripts; problem introduced with the recent
8106 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8107 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8108 since it's used in non-static inline functions now.
8110 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

8603 arms of an 'if', not using conditional expressions; otherwise GDB
8604 complains about the types in the unevaluated arm when the argument
8605 is an integer literal.
8606 (xgetint): Simplify expression.
8607 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8608 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8609 Zaretskii in <http://bugs.gnu.org/12036#13>.
8610 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8611 needed now that we have gdb_make_enums_visible.
8612 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8613 (enum enum_USE_LSB_TAG):
8614 New enum types, packaging up enums that need to be exported to GDB.
8616 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8618 Utility function to make a list from specified amount of objects.

8632 * xdisp.c (syms_of_xdisp): Likewise.
8633 * xfns.c (syms_of_xfns): Likewise.
8635 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8637 Fast save_excursion_save and save_excursion_restore.
8638 * lisp.h (struct Lisp_Excursion): New data type.
8639 (PVEC_EXCURSION): New pseudovector type.
8640 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8641 to deal with it. Adjust comments.
8642 (init_marker, attach_marker): New prototype.
8643 (unchain_marker): Adjust prototype.
8644 * marker.c (attach_marker): Change to global.

8652 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8654 Fix export of symbols to GDB (Bug#12036).
8655 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8656 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8657 emacs.c, as this is a more-suitable home. Had this been done earlier
8658 the fix for 12036 would have avoided some of the problems noted in
8659 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8660 would have been more obvious.
8661 * emacs.c: Do not include <verify.h>; no longer needed.
8662 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8663 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8664 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8665 Remove; now done in lisp.h.
8666 * lisp.h (PUBLISH_TO_GDB): New macro.
8667 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8668 (DATA_SEG_BITS): Use it.
8669 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8670 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8671 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8672 not be usable in #if. This simplifies things.
8674 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8676 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8678 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8680 Simplify export of symbols to GDB (Bug#12036).
8681 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8682 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8683 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8684 Adjust to changes in lisp.h and emacs.c, by using
8685 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8686 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8687 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8688 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8689 instead of gdb_valbits.
8690 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8691 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8692 instead of gdb_array_mark_flag.
8693 (xboolvector): Get size from $->size, not $->header.size.
8694 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8695 (xreload, hook-run, hookpost-run): Remove.
8696 * emacs.c: Include <verify.h>.
8697 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8698 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8700 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8701 (gdb_USE_LSB_TAG): New enum constants.
8702 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8703 Also define these as enum constants, so they're visible to GDB.
8704 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8705 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8706 as constants, so they're visible to GDB.
8707 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8708 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8709 Now enum constants, not macros, so they're visible to GDB.
8710 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8711 more convenient now. All uses changed.
8712 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8713 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8715 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8720 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8722 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8723 add argument, tune behavior, and adjust all callers.
8725 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8727 Use typedef for EMACS_INT, EMACS_UINT.
8728 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8729 than macros. This simplifies debugging in the usual case, since
8730 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8731 and it allows expressions involving EMACS_INT casts.
8732 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8734 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8736 * nsterm.m (ns_read_socket): Return early if there is a modal

8742 that FOCUS-FRAME can be omitted.
8744 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8746 Adjust buffer text indirection counters at the end of Fkill_buffer.
8747 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8748 buffer is definitely dead. This should really fix an issue reported
8749 by Christoph Scholtes again. (Bug#12007).
8750 (init_buffer_once): Initialize indirection counters of
8751 buffer_defaults and buffer_local_symbols (for sanity and safety).
8753 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8755 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8756 and continuation glyphs on tooltip frames, leave them at zero.
8757 Avoids continued lines in tooltips. (Bug#11832)
8759 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8761 Simplify copy_overlay.
8762 * buffer.c (copy_overlay): Simplify. Use build_marker.

8784 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8786 Swap buffer text indirection counters in Fbuffer_swap_text.
8787 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8788 This avoids crash reported by Christoph Scholtes at
8789 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8791 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8793 * nsmenu.m (Popdown_data): New struct.
8794 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8796 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

8798 and autorelease them. Also autorelease img and matrix (Bug#12005).
8799 (dealloc): Remove (Bug#12005).

8816 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8818 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8819 as it's limited by the amount of memory, not by INT_MAX.
8821 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8823 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8824 in special-event-map. See the discussion at

8883 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8884 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8885 Adjust users accordingly.
8886 * font.h (font_open_by_name): Adjust prototype.

8905 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8906 'for_each_per_buffer_object_at'.
8907 All uses changed. It's better to use upper-case for macros that
8908 cannot be implemented as functions, to give the reader a clue
8909 that they're special.

8954 * intervals.c (merge_interval_right, merge_interval_left):
8955 Do not zero out this interval if it is absorbed by its children,
8956 as this interval's total length doesn't change in that case. See
8957 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8959 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8961 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8962 when invoking (make-bool-vector N t) and N is a positive

8965 Remove some struct layout assumptions in bool vectors.
8966 * alloc.c (bool_header_size): New constant.
8967 (header_size, word_size): Move earlier, as they're now used earlier.

8970 padding before the data member of a bool vector.
8971 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
8972 than doing the check by hand with an abort ().
8974 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8976 * eval.c (Fdefvar): Don't check constants since we only set the var if
8977 it's not yet defined anyway (bug#11904).
8979 * lisp.h (last_undo_boundary): Declare new var.
8980 * keyboard.c (command_loop_1): Set it.
8981 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8982 were auto-added by the command loop (bug#11774).
8984 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
8986 * w32font.c (Qsymbol): Remove local definition.

9487 * s/gnu.h: Remove file, which is now empty.
9489 * s/gnu.h, s/gnu-linux.h:
9490 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
9492 2012-07-11 John Wiegley <johnw@newartisans.com>
9494 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9495 function attribute, so we only use it if it exists in the
9498 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9500 Avoid call to strlen in fast_c_string_match_ignore_case.
9501 * search.c (fast_c_string_match_ignore_case): Change to use
9502 length argument. Adjust users accordingly.
9503 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
9505 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

9546 Remove "#define unix" that is no longer needed (Bug#11905).
9547 * s/aix4-2.h (unix): Remove; no longer needed.
9549 EMACS_TIME simplification (Bug#11875).
9550 This replaces macros (which typically do not work in GDB)
9551 with functions, typedefs and enums, making the code easier to debug.
9552 The functional style also makes code easier to read and maintain.
9553 * systime.h: Include <sys/time.h> on all hosts, not just if
9554 WINDOWSNT, since 'struct timeval' is needed in general.
9555 (EMACS_TIME): Now a typedef, not a macro.
9556 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9558 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9561 (EMACS_TIME_LE): Now functions, not macros.
9562 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9563 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9564 which are not functions. All uses rewritten to use:
9565 (make_emacs_time): New function.
9566 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9567 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9568 not functions. All uses rewritten to use the following, respectively:
9569 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9570 (add_emacs_time, sub_emacs_time): New functions.
9571 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9572 * fileio.c (Fcopy_file):
9573 * xterm.c (XTflash): Get the current time closer to when it's used.
9574 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9580 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
9581 * frame.c (Fmake_terminal_frame):
9582 * gtkutil.c (get_utf8_string):
9584 * nsmenu.m (ns_update_menubar):
9585 * regex.c (regerror):
9586 Prefer memcpy to strncpy and strncat when either will do.
9587 * fileio.c (Fsubstitute_in_file_name):
9588 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9589 (menu_separator_name_p):
9590 * nsmenu.m (ns_update_menubar):
9591 Prefer memcmp to strncmp when either will do.
9592 * nsterm.m: Include <ftoastr.h>.
9594 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9595 Prefer snprintf to strncpy.
9596 * nsterm.m (ns_term_init):
9597 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9598 * nsterm.m (ns_term_init):
9599 Avoid the need for strncpy, by using build_string or
9600 make_unibyte_string directly. Use dtoastr, not snprintf.
9601 * process.c (Fmake_network_process): Diagnose service names that
9602 are too long, rather than silently truncating them or creating
9603 non-null-terminated names.
9604 (Fnetwork_interface_info): Likewise, for interface names.
9605 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9606 Prefer sprintf to strncat.
9607 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9608 Prefer vsnprintf to vsprintf + strncpy.
9610 2012-07-10 Glenn Morris <rgm@gnu.org>
9612 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9613 Clarify fallback case.
9615 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9617 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9618 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9619 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9620 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9621 where argument type is known to be a Lisp_Cons.
9623 2012-07-10 Tom Tromey <tromey@redhat.com>
9625 * bytecode.c (BYTE_CODE_THREADED): New macro.
9626 (BYTE_CODES): New macro. Replaces all old byte-code defines.
9627 (enum byte_code_op): New type.

9633 Optimize pure C strings initialization.
9634 * lisp.h (make_pure_string): Fix prototype.
9635 (build_pure_c_string): New function, defined as static inline. This
9636 provides a better opportunity to optimize away calls to strlen when
9637 the function is called with compile-time constant argument.
9638 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9639 argument, adjust users accordingly. Use build_pure_c_string where
9641 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9642 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9643 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9645 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9647 Avoid calls to strlen in miscellaneous functions.
9648 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9649 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9650 * lread.c (openp): Likewise.
9652 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9654 Avoid calls to strlen in path processing functions.
9655 * fileio.c (file_name_as_directory): Add comment. Change to add
9656 srclen argument and return the length of result. Adjust users
9658 (directory_file_name): Fix comment. Change to add srclen argument,
9659 swap 1st and 2nd arguments to obey the common convention.
9660 Adjust users accordingly.
9661 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9663 2012-07-10 Glenn Morris <rgm@gnu.org>
9665 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9666 Move PENDING_OUTPUT_COUNT definition to configure.
9668 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9669 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9670 * s/gnu.h (DATA_START): Move definitions to configure.
9672 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9673 We include usg5-4-common.h, which defines them both.
9675 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9676 O_RDONLY already includes it).
9678 Stop ns builds setting the EMACSLOADPATH environment variable.
9679 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9680 Now it does not set EMACSLOADPATH, just returns the load-path string.
9681 * nsterm.h: Update accordingly.
9682 * lread.c [HAVE_NS]: Include nsterm.h.
9683 (init_lread) [HAVE_NS]: Use ns_load_path.
9684 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9686 2012-07-09 Glenn Morris <rgm@gnu.org>
9688 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9689 since the included bsd-common.h does so.
9691 Stop ns builds setting the EMACSPATH environment variable.
9692 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9693 (ns_init_paths): Do not set EMACSPATH.
9694 * nsterm.h (ns_exec_path): Add it.
9695 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9698 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9700 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9702 * process.c (wait_reading_process_output): 'waitchannels' was unset
9703 when read_kbd || !NILP (wait_for_cell); fix this.
9705 Add GCC-style 'const' attribute to functions that can use it.
9706 * character.h (char_resolve_modifier_mask):
9707 * keyboard.h (make_ctrl_char):
9708 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9709 (init_character_once, next_almost_prime, init_fns, init_image)
9710 (flush_pending_output, init_sound):
9711 * mem-limits.h (start_of_data):

9715 Declare the dummy function with ATTRIBUTE_CONST.
9716 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9717 Add decls with ATTRIBUTE_CONST.
9719 Minor improvements to make_formatted_string.
9720 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9721 where int is good enough, as vsprintf returns an int.
9722 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9724 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9726 Use make_formatted_string to avoid double length calculation.
9727 * lisp.h (make_formatted_string): New prototype.

9733 * frame.c (make_terminal_frame, set_term_frame_name)
9734 (x_report_frame_params): Likewise.
9735 * image.c (gs_load): Likewise.
9736 * minibuf.c (get_minibuffer): Likewise.

9751 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9753 Move marker debugging code under MARKER_DEBUG.
9754 * marker.c (MARKER_DEBUG): Move marker debugging code under
9755 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9756 for bootstrap with --enable-checking (~3x slowdown reported
9757 by Juanma Barranquero <lekktu@gmail.com>).
9758 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9760 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9762 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9763 See <http://bugs.gnu.org/11825#29>.
9765 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9767 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9768 has no font, use the frame's font. (Bug#11813)
9769 (display_line): Add commentary about displaying truncation glyphs
9771 (produce_special_glyphs): Move here from term.c.
9773 * term.c (produce_special_glyphs): Move to xdisp.c.
9775 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9778 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9780 * xdisp.c (display_line): Avoid warning about implicit declaration
9783 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9785 * lisp.h: Remove empty conditional.
9787 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9789 * lread.c (load_path_check): Now static.
9791 Fix some minor --with-ns problems found by static checking.
9792 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9793 (x_set_font) [!HAVE_X_WINDOWS]:
9794 * image.c (xpm_load_image) [HAVE_NS]:
9795 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9796 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9797 Remove unused local.
9798 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9799 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9800 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9801 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9802 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9803 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9804 Fix pointer signedness problem.
9805 * xfaces.c (FRAME_X_FONT_TABLE):
9806 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9808 2012-07-07 Glenn Morris <rgm@gnu.org>
9810 * lread.c (load_path_check): New function, split from init_lread.
9811 (init_lread): Reorganize. Motivation:
9812 If EMACSLOADPATH is set, check/warn about that rather than the
9813 defaults, which we are not going to use. Hence we can remove
9814 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9815 Don't warn if site-lisp directories are missing.
9816 If not installed, start from a blank load-path, since
9817 PATH_LOADSEARCH refers to the eventual installation directories.
9819 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9821 Support truncation and continuation glyphs on GUI frames, when
9822 fringes are disabled. (Bug#11832)
9823 * xdisp.c (init_iterator): Get dimensions of truncation and
9824 continuation glyphs even if on GUI frames.
9825 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9826 or both, are absent.
9827 (start_display, move_it_in_display_line_to): Handle the case of a
9828 GUI frame without a fringe to display continuation or truncation
9830 (insert_left_trunc_glyphs): Support GUI frames: make sure
9831 truncation glyphs overwrite enough glyphs from the current line to
9832 have sufficient space in pixels.
9833 (display_line): Support truncation and continuation glyphs on GUI
9834 frames. If some spare pixels are left on the line after inserting
9835 the truncation glyphs, fill that space with a stretch glyph of a
9836 suitably computed width.
9838 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9839 produce_glyphs, to support GUI sessions.
9841 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9843 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9845 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9847 Do not require float-time's arg to fit in time_t (Bug#11825).
9848 This works better on hosts where time_t is unsigned, and where
9849 float-time is applied to the (negative) difference between two times.
9850 * editfns.c (decode_time_components): Last arg is now double *,
9851 not int *, and means to store all the result as a double, without
9852 worrying about whether the seconds part fits in time_t.
9853 All callers changed.
9854 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9855 All callers changed.
9856 (Ffloat_time): Do not fail merely because the specified time falls
9857 outside of time_t range.
9859 2012-07-07 Glenn Morris <rgm@gnu.org>
9861 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9865 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9867 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9868 Update dependencies.
9870 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9872 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9874 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9875 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9876 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9877 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9878 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9879 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9881 * xfont.c (compare_font_names): Redo to omit the need for casts.
9883 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9885 * xfns.c (Fx_change_window_property): Doc fix.
9886 * w32fns.c (Fx_change_window_property): Doc fix.
9888 * w32fns.c (Fx_window_property): Accept the same arguments as the
9889 X Windows version. Doc fix.
9890 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9892 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9893 Eli Zaretskii <eliz@gnu.org>
9895 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9896 Windows-specific code from nt/config.nt moved here.
9897 Obsolete settings removed.
9899 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9901 * process.c: Avoid unnecessary calls to gettime.
9902 (wait_reading_process_output): Don't get the time of day
9903 when gobbling data immediately and not waiting, as there's no need
9904 for it in that case. This removes a FIXME.
9906 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9908 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9909 is defined (Bug#11768).
9911 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9913 Fix marker debugging code.
9914 * marker.c (byte_char_debug_check): Do not perform the check
9915 if buffer is not multibyte.
9916 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9917 Call byte_char_debug_check with correct arguments.
9919 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9921 Compile marker debugging code only if ENABLE_CHECKING is defined.
9922 * marker.c (byte_char_debug_check, count_markers):
9923 Use only if ENABLE_CHECKING is defined.
9924 (byte_debug_flag): Remove.
9925 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9926 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9928 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9930 Avoid code repetition in marker-related functions.
9931 * marker.c (attach_marker): New function.
9932 (Fset_marker, set_marker_restricted, set_marker_both)
9933 (set_marker_restricted_both): Use it.
9934 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9935 Consistently rename charno to charpos.
9936 (marker_position): Add eassert.
9937 (marker_byte_position): Convert to eassert.

9949 * lisp.h (build_marker): New prototype.
9950 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9951 * composite.c (autocmp_chars): Likewise.
9952 * editfns.c (buildmark): Remove.
9953 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9954 (save_restriction_save): Use build_marker.
9955 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9956 * window.c (save_window_save): Likewise.
9958 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9960 Do not use Fdelete_overlay in delete_all_overlays
9961 to avoid redundant calls to unchain_overlay.
9962 * buffer.c (drop_overlay): New function.
9963 (delete_all_overlays, Fdelete_overlay): Use it.
9964 * minibuf.c (get_minibuffer): Fix comment.
9966 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9968 Port to OpenBSD 5.1 amd64.
9969 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9970 This is needed for OpenBSD, and should be harmless on all BSD systems.
9971 Also, include <sys/sysctl.h>, as it should be available on all
9972 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9973 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9974 use p_pid member, not kp_proc.pid.
9976 2012-07-06 Glenn Morris <rgm@gnu.org>
9978 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9980 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9982 More xmalloc and related cleanup.
9983 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9991 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9993 Omit needless casts involving void * pointers and allocation.
9994 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9995 as the former is more robust if P's type is changed.
9996 Prefer xzalloc to xmalloc + memset 0.
9997 Simplify malloc-or-realloc to realloc.
9998 Don't worry about xmalloc returning a null pointer.
9999 Prefer xstrdup to xmalloc + strcpy.
10000 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10002 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10003 alloca of a constant.
10005 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10007 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10008 hscroll is larger than the line width. Fixes long and futile
10009 looping inside extend_face_to_end_of_line (on a TTY) producing
10010 glyphs that are not needed and thrown away.
10012 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10014 * marker.c (set_marker_restricted_both): Simplify by using
10017 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10019 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10021 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10023 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10024 not defined (Bug#11768).
10025 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10026 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10027 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10028 followed by gtk_box_set_homogeneous (Bug#11768).
10029 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10030 (update_theme_scrollbar_width, xg_create_scroll_bar):
10031 Use gtk_scrollbar_new (Bug#11768).

10033 (is_box_type): New function (Bug#11768).
10034 (xg_tool_item_stale_p): Call is_box_type.
10035 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10036 with default display (Bug#11768).
10038 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10040 * xdisp.c (window_hscroll_limited): New function.
10041 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10042 coordinates when window's hscroll is set to insanely large
10043 values. (Bug#11857)
10045 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10106 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10108 * fileio.c (time_error_value): Check the right error number.
10109 Problem reported by Troels Nielsen in
10110 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10112 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10114 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10115 This should be fixed in a better way; see Eli Zaretskii in
10116 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10117 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10119 * fileio.c (time_error_value): Rename from special_mtime.
10120 The old name's problems were noted by Eli Zaretskii in
10121 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10123 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10124 This variable's comment says Emacs needs at least one GDB-visible
10125 symbol of type enum pvec_type, to work around GDB problems.
10126 The symbol's value doesn't matter.
10128 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10129 that causes compilation to fail on pre-C99 compilers.
10131 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10133 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10134 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10136 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10138 * buffer.c (init_buffer_once): Fix initialization of
10139 headers for buffer_defaults and buffer_local_symbols.
10140 Reported by Juanma Barranquero <lekktu@gmail.com>.
10142 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10144 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10145 * lisp.h (enum pvec_type): Use fewer bits.
10146 (PSEUDOVECTOR_SIZE_BITS): New constant.
10147 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10148 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10149 change in pvec_type.
10150 (PSEUDOVECTOR_TYPEP): New macro.
10151 (TYPED_PSEUDOVECTORP): Use it.
10152 * fns.c (internal_equal): Adapt code to extract pvectype.
10153 * emacs.c (gdb_pvec_type): Update type.
10154 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10155 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10156 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10157 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10158 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10159 abusing vector->header.next.nbytes.
10160 (live_vector_p): Use PVEC_TYPE.
10161 (mark_object): Adapt code to extract pvectype. Use switch.
10163 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10165 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10166 Tighten new eassert a bit.
10168 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10170 Fix compilation with --enable-gcc-warnings and -O1
10171 optimization level.
10172 * doprnt.c (doprnt): Change type of tem to int, initialize
10173 to avoid compiler warning. Add eassert.
10174 * search.c (simple_search): Initialize match_byte to avoid
10175 compiler warning. Add eassert.
10177 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10179 Avoid weird behavior with large horizontal scrolls.
10180 Without this change, for example, large hscroll values would
10181 mess up Emacs's display on Fedora 15 x86, presumably due to
10182 overflows in int calculations in the display code.
10183 Also, if buffers had long lines, Emacs would freeze.
10184 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10185 (set_window_hscroll): New function, containing the old guts of
10186 Fset_window_hscroll. Return the clipped value.
10187 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10188 This avoids the need to check against PTRDIFF_MAX.
10190 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10192 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10194 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10196 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10198 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10199 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10200 since GCC 4.4.6 issues a bogus warning for them.
10202 Fix bugs in file timestamp newness comparisons.
10203 * fileio.c (Ffile_newer_than_file_p):
10204 * lread.c (Fload): Use full timestamp resolution of files,
10205 not just the 1-second resolution, so that files that are only
10206 slightly newer still count as newer.
10207 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10208 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10210 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10212 * fileio.c: Improve handling of file time marker. (Bug#11852)
10213 (special_mtime): New function.
10214 (Finsert_file_contents, Fverify_visited_file_modtime):
10215 Use it to set special mtime values consistently.
10217 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10219 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10220 marker for non-existing file. (Bug#11852)
10222 2012-07-03 Glenn Morris <rgm@gnu.org>
10224 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10225 and did not make it into globals.h).
10227 2012-07-03 Tom Tromey <tromey@redhat.com>
10229 * window.c (Fset_window_margins, Fset_window_fringes)
10230 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10231 * textprop.c (Fprevious_property_change): No longer static.

10256 * font.h: Remove EXFUNs.
10257 * dosfns.c (system_process_attributes): Remove EXFUN.
10258 * keymap.h: Remove EXFUNs.
10259 * lisp.h: Remove EXFUNs.
10260 * w32term.h: Remove EXFUNs.
10261 * window.h: Remove EXFUNs.
10262 * xsettings.h: Remove EXFUN.
10263 * xterm.h: Remove EXFUN.
10265 2012-07-03 Glenn Morris <rgm@gnu.org>
10267 * lisp.h (Frandom): Make it visible to C.
10268 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10269 buffer for invisible buffers. (Bug#1229)
10271 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10273 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10274 values which aren't power of 2.
10275 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10276 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10279 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10281 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10283 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10285 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10287 * alloc.c (allocate_vector_block): Remove redundant
10288 calls to mallopt if DOUG_LEA_MALLOC is defined.
10289 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10290 avoid calls to mallopt if zero_vector is returned.
10292 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10294 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10295 is enabled, avoid dereferencing NULL current_sblock if
10298 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10300 Cleanup basic buffer management.
10301 * buffer.h (struct buffer): Change layout to use generic vector
10302 marking code. Fix some comments. Change type of 'clip_changed'
10303 to bitfield. Remove unused #ifndef old.
10304 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10305 (GET_OVERLAYS_AT): Fix indentation.
10306 (for_each_per_buffer_object_at): New macro.
10307 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10308 (Fbuffer_local_variables): Use it.
10309 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10310 * alloc.c (allocate_buffer): Adjust to match new layout of
10311 struct buffer. Fix comment.
10312 (mark_overlay): New function.
10313 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10314 Lisp area of struct buffer.
10315 (mark_object): Use it. Adjust marking of misc objects
10316 and related comments.
10318 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10320 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10321 wrapper that is not needed because the wrapped code is a no-op (zero
10322 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10323 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10325 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10327 * alloc.c (mark_buffer): Simplify. Remove prototype.
10328 (mark_object): Add comment. Reorganize marking of vector-like
10329 objects. Use CHECK_LIVE for all vector-like objects except buffers
10330 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10331 Avoid redundant calls to mark_vectorlike for bool vectors.
10333 2012-06-30 Glenn Morris <rgm@gnu.org>
10335 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10337 * epaths.in (PATH_SITELOADSEARCH): New.
10338 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10339 This is rather than relying on --enable-locallisppath elements
10340 having "site-lisp" in their names. (Bug#10208#25, 11658)
10342 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10344 * w32proc.c (sys_select): Accept and ignore one more argument.
10346 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10348 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10349 (pselect) [!MS_DOS]: Redirect to sys_select.
10351 * sysdep.c: Don't include dos.h and dosfns.h.
10353 * process.c (sys_select):
10354 * msdos.c (sys_select): Accept one more argument and ignore it.
10356 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10357 adapt data types and code to that.
10360 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10361 which clashes with the gnulib function of the same name.
10363 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10365 * font.c (font_style_to_value, font_style_symbolic)
10366 (font_prop_validate_style): Add type checks for values in
10369 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10371 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10374 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10376 * xdisp.c (try_window_id): Undo last change.
10378 * w32.c (getwd): Adjust commentary about startup_dir.
10379 (init_environment): Always call sys_access, even in non-MSVC
10380 builds. Don't chdir to the directory of the Emacs executable.
10381 This undoes code from 1997 which was justified by the need to
10382 "avoid conflicts when removing and renaming directories". But its
10383 downside was that every relative file name was being interpreted
10384 relative to the directory of the Emacs executable, which can never
10385 be TRT. In particular, it broke sys_access when called with
10386 relative file names.
10387 (sys_access): Map GetLastError to errno.

10579 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10581 Use sprintf return value instead of invoking strlen on result.
10582 In the old days this wasn't portable, since some sprintf
10583 implementations returned char *. But they died out years ago and
10584 Emacs already assumes sprintf returns int.
10585 Similarly for float_to_string.
10586 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10594 Use sprintf or float_to_string result to avoid need to call strlen.
10595 * data.c (Fnumber_to_string):
10596 Use make_unibyte_string, since the string must be ASCII.
10597 * lisp.h, print.c (float_to_string): Now returns int length.
10598 * term.c (produce_glyphless_glyph):
10599 Use sprintf result rather than recomputing it.
10601 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10609 strcasecmp if available.

10630 * xfns.c (x_window): Remove redundant cast.
10632 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10634 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10637 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10639 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10640 instead of truncating it to 63 (admittedly a generous limit).
10642 * process.c: Fix spelling and caps in comments.

10700 * keyboard.c (kbd_buffer_get_event):
10701 * process.c (Faccept_process_output):
10702 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10703 This improves on the previous patch, which introduced a bug
10704 when time_t is unsigned and as wide as intmax_t.
10705 See <http://bugs.gnu.org/9000#51>.
10707 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10736 language ID in the event parameters.
10738 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10739 event.code, not the obscure "character set ID".

10772 Support higher-resolution time stamps (Bug#9000).
10773 The time stamps are only nanosecond-resolution at the C level,
10774 since that's the best that any real-world system supports now.
10775 But they are picosecond-resolution at the Lisp level, as that's
10776 easy, and leaves room for future OS improvements.
10778 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10781 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10782 Don't get current time unless it's needed.
10784 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10785 now provides it if it's absent.
10786 (start_atimer): Port to higher-res time stamps.
10787 Check for time stamp overflow. Don't get current time more
10788 often than is needed.
10790 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10791 Include systime.h, not time.h.
10792 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10794 * dired.c: Include stat-time.h.
10795 (Ffile-attributes): File times now have higher resolution.
10797 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10798 (struct image): Timestamp now has higher resolution.
10800 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10801 has at least microseconds now. All uses removed.
10802 (update_frame, update_single_window, update_window, update_frame_1)
10803 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10804 (duration_to_sec_usec): Remove; no longer needed.
10806 * editfns.c (time_overflow): Now extern.
10807 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10808 (float-time, Fformat_time_string, Fcurrent_time_string)

10811 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10812 (decode_time_components, lisp_seconds_argument): New functions.
10813 (make_time): Now static.
10814 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10815 Report an error if the time is invalid, rather than having the caller
10818 * fileio.c: Include <stat-time.h>
10819 (Fcopy_file): Copy higher-resolution time stamps.
10820 Prefer to set the time stamp via a file descriptor if that works.
10821 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10822 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10823 (Fvisited_file_modtime, Fset_visited_file_modtime):
10824 Support higher-resolution time stamps.
10826 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10828 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10830 * image.c (prepare_image_for_display, clear_image_cache)
10831 (lookup_image): Port to higer-resolution time stamps.
10833 * keyboard.c (start_polling, bind_polling_period):
10834 Check for time stamp overflow.
10835 (read_char, kbd_buffer_get_event, timer_start_idle)
10836 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10837 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10838 Port to higher-resolution time stamps. Do not assume time_t is signed.
10839 (decode_timer): New function. Timers are now vectors of length 9,
10840 not 8, to accommodate the picosecond component.
10841 (timer_check_2): Use it.
10843 * nsterm.m (select_timeout, timeval_subtract): Remove.
10844 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10845 as they're a bit more accurate and handle overflow better.
10846 (ns_select): Change prototype to be compatible with pselect.
10847 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10848 * nsterm.h (ns_select): Adjust prototype.
10850 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10851 us-resolution time stamps.
10852 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10854 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10856 * lisp.h (time_overflow): New decl.

10861 Now counts nanoseconds, not microseconds.
10862 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

10865 (wait_reading_process_output):
10866 Port to ns-resolution time stamps.
10867 (Faccept_process_output, wait_reading_process_output):
10868 Check for time stamp overflow. Do not assume time_t is signed.
10869 (select_wrapper): Remove; we now use pselect.
10870 (Fprocess_attributes): Now generates ns-resolution time stamps.
10872 * sysdep.c: Include utimens.h. Don't include utime.h
10873 or worry about struct utimbuf; gnulib does that for us now.
10874 (gettimeofday): Remove; gnulib provides a substitute.
10875 (make_timeval): New function.
10876 (set_file_times): Now sets ns-resolution time stamps.
10877 New arg FD; all uses changed.

10880 Now returns ns-resolution time stamp. All uses changed.
10881 Check for time stamp overflow.

10884 provides a substitute now.
10886 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10887 since it guarantees struct timespec.
10888 (EMACS_TIME): Now struct timespec, so that we can support
10889 ns-resolution time stamps.
10890 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10891 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10892 (EMACS_USECS): Remove.
10893 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10894 so multiply the arg by 1000 before storing it.

10904 (make_timeval, make_lisp_time, decode_time_components): New decls.
10905 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10906 that it mishandled time_t overflow. You can't compare by subtracting!
10907 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10908 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10910 * term.c: Include <sys/time.h>.

10915 in the undo buffer.
10916 (Fprimitive_undo): Use them when restoring time stamps.
10918 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10919 (w32_get_internal_run_time):
10920 Port to higher-resolution Emacs time stamps.
10921 (ltime): Now accepts single 64-bit integer, as that's more convenient
10924 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10926 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10927 for compatibility with pselect. Support ns-resolution time stamps.
10929 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10931 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10932 Check for time stamp overflow, and support ns-resolution time stamps.
10934 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10935 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10936 (timeval_subtract): Remove; no longer needed.
10937 (XTflash, XTring_bell, x_wait_for_event):
10938 Port to ns-resolution time stamps. Don't assume time_t is signed.

10944 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10946 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10947 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10948 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10949 staticidx goes up to 1597 out of 1600 = 0x640.)
10951 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10953 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10954 Otherwise, the umask might be mistakenly 0 while handling input signals.
10956 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10958 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10974 frame's selected window and its terminal's top-frame.
10975 (unwind_format_mode_line): Restore them.
10976 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10978 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10979 since tty frames can be explicitly named.
10980 (prepare_menu_bars): Likewise.
10982 * term.c (Ftty_top_frame): New function.
10984 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10987 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10988 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10989 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10990 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10997 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10999 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11000 gets killed during executing of this function (Bug#11665).
11001 Try to always return Qt when the buffer has been actually killed.
11002 (Vkill_buffer_query_functions): In doc-string say that functions
11003 run by this hook should not change the current buffer.
11005 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11007 Fix recently-introduced process.c problems found by static checking.

11027 * lisp.h (eassert): Assume C89 or later.
11028 This removes the need for CHECK.
11029 (CHECK): Remove. Its comments about always evaluating its
11030 argument were confusing, as 'eassert' typically does not evaluate
11033 * coding.c (produce_chars): Use ptrdiff_t, not int.
11035 * xterm.c (x_draw_underwave): Check for integer overflow.
11036 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11224 Use an inline function on all platforms when using the union type,

11311 * xdisp.c (vmessage): Treat frame message as multibyte.
11312 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
11313 would generate the diagnostic "Making \302\247 buffer-local while

11318 * dispnew.c (showing_window_margins_p): Undo last change, which
11319 was done due to an inadvertent commit.

11340 Block-based vector allocation of small vectors.
11341 * lisp.h (struct vectorlike_header): New field `nbytes',
11342 adjust comment accordingly.
11343 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11344 to denote vector blocks. Adjust users (live_vector_p,

11361 (init_alloc_once): Add call to init_vectors.
11363 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11365 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11367 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11369 * doprnt.c (doprnt): Truncate multibyte char correctly.
11370 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11371 would mishandle a string argument "Xc" if X was a multibyte
11372 character of length 2: it would truncate after X's first byte
11373 rather than including all of X.
11375 2012-06-06 Chong Yidong <cyd@gnu.org>
11377 * buffer.c (word_wrap): Doc fix.
11379 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11391 binary via PaX flags if the paxctl utility is available.
11392 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11393 Restore PaX flags to their default. (Bug#11398)
11395 2012-06-03 Chong Yidong <cyd@gnu.org>
11397 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11398 buffer (Bug#11226).

11405 position is past the end of the mode line string.
11407 * buffer.c (buffer_local_value_1): New function, split from
11408 Fbuffer_local_value; can return Qunbound.
11409 (Fbuffer_local_value): Use it.
11410 (Vmode_line_format): Docstring tweaks.
11412 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

11424 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11426 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11427 Convert pctcpu and pctmem to Lisp float properly.
11428 Let the compiler fold better, as 100.0/0x8000 is exact.
11430 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11432 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11435 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11439 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11441 For a 'struct window', replace some Lisp_Object fields to
11442 bitfields where appropriate, remove unused fields.
11443 * window.h (struct window): Remove unused 'last_mark_x' and
11444 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11445 change its type from Lisp_Object to bitfield.
11446 Change type of 'force_start', 'optional_new_start',
11447 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11448 fields from Lisp_Object to bitfield. Adjust users accordingly.
11450 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11452 Pacify gcc -Wdouble-precision when using Xaw.
11453 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11454 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11455 Use 'float' consistently, rather than 'float' in most places
11456 and 'double' in a couple of places.
11458 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11460 * xdisp.c (handle_stop): Detect whether we have overlay strings
11461 loaded by testing it->current.overlay_string_index to be
11462 non-negative, instead of checking whether n_overlay_strings is
11463 positive. (Bug#11587)
11465 2012-05-31 Chong Yidong <cyd@gnu.org>
11467 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11471 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11473 * search.c (search_buffer): Remove calls to
11474 r_alloc_inhibit_buffer_relocation, as it is now called by
11475 maybe_unify_char, which was the cause of relocation of buffer text
11478 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11480 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11481 for the duration of call to load_charset, to avoid problems with
11482 callers of maybe_unify_char that access buffer text through C
11485 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11486 decrement the inhibition flag, instead of just setting or
11489 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11491 Remove obsolete '#define static' cruft.
11492 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11493 This #undef was "temporary" in 2000; it is no longer needed
11494 now that '#define static' has gone away.
11495 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11496 (gray_bitmap_bits): Remove; no longer needed.
11497 All uses replaced with definiens.
11498 * xterm.c: Include "bitmaps/gray.xbm".
11500 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11502 Clean up __executable_start, monstartup when --enable-profiling.
11503 The following changes affect the code only when profiling.
11504 * dispnew.c (__executable_start): Rename from safe_bcopy.
11505 Define only on platforms that need it.
11506 * emacs.c: Include <sys/gmon.h> when profiling.
11507 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11508 (__executable_start): Remove decl, since lisp.h does it now.
11509 (safe_bcopy): Remove decl; no longer has that name.
11510 (main): Coalesce #if into single bit of code, for simplicity.
11511 Cast pointers to uintptr_t, since standard libraries want integers
11513 * lisp.h (__executable_start): New decl.
11515 2012-05-31 Glenn Morris <rgm@gnu.org>
11517 * image.c (Fimagemagick_types): Doc fix.

11538 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11540 Do not create empty overlays with the evaporate property (Bug#9642).
11541 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11542 Bug#9642, but explicitly check that the buffer the overlay would
11543 be moved to is live and rearrange lines to make sure that errors
11544 will not put the overlay in an inconsistent state.
11545 (Fdelete_overlay): Cosmetics.
11547 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11549 * w32term.c (my_bring_window_to_top): New function.
11550 (x_raise_frame): Use handle returned by DeferWindowPos, which
11551 could be different from the original one.

11561 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11563 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11564 This avoids undefined behavior that might cause the eassert
11565 to not catch an out-of-range value.
11567 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11569 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11570 Update dependencies.
11572 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11574 * bidi.c (bidi_mirror_char): Fix last change.
11576 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11581 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11583 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11584 Only r_alloc_inhibit_buffer_relocation needed to be added;
11585 the others were already declared.
11587 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11588 before checking whether it's out of range. Put the check inside
11590 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11592 2012-05-27 Ken Brown <kbrown@cornell.edu>
11594 * callproc.c (Fcall_process): Restore a line that was accidentally
11595 commented out in the 2011-02-13 change (bug#11547).
11597 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11599 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11600 defined on ralloc.c.
11602 * buffer.c [REL_ALLOC]: Remove prototypes of
11603 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11604 they are now on lisp.h.
11606 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11608 * search.c (search_buffer): Use it to inhibit relocation of buffer
11609 text while re_search_2 is doing its job, because re_search_2 is
11610 passed C pointers to buffer text. (Bug#11519)
11612 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11613 Update value to 24.
11615 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11616 state after an additional call to move_it_in_display_line_to, keep
11617 the values of it->max_ascent and it->max_descent found for the
11619 (pos_visible_p): Revert the comparison against bottom_y to what it
11620 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11623 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11625 Fix coding-related core dumps with gcc -ftrapv.
11626 The code was computing A - B, where A and B are pointers, and B is
11627 random garbage. This can lead to core dumps on platforms that
11628 have special pointer registers, and it also leads to core dumps on
11629 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11630 A - B only when B is initialized properly.
11631 * coding.c (coding_set_source, coding_set_destination): Return void.
11632 (coding_change_source, coding_change_destinations): New functions,
11633 with the old behaviors of coding_set_source and coding_set_destination.
11634 All callers that need an offset changed to use these new functions.
11636 2012-05-26 Glenn Morris <rgm@gnu.org>
11638 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

11644 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11646 * w32console.c: Include window.h.
11647 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11649 (initialize_w32_display): Initialize mouse-highlight data.
11651 * w32inevt.c: Include termchar.h and window.h.
11652 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11653 moves, call note_mouse_highlight. If help_echo changed, call
11654 gen_help_event to produce help-echo message in the echo area.
11655 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11658 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11660 * lread.c (read1): Simplify slightly to avoid an overflow warning
11661 with GCC 4.7.0 on x86-64.
11663 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11665 * bidi.c (bidi_mirror_char): Revert last change: an int is
11666 definitely wide enough here.
11668 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

11678 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11680 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11682 Use int, not EMACS_INT, where int is wide enough.
11683 (inhibit_garbage_collection, Fgarbage_collect):
11684 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11685 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11686 int might not be wide enough.
11687 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11688 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11689 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11690 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11691 (bidi_level_of_next_char, bidi_move_to_visually_next):
11692 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11693 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11694 (Fkill_buffer, Fset_buffer_major_mode)
11695 (advance_to_char_boundary, Fbuffer_swap_text)

11697 (overlay_touches_p, struct sortvec, record_overlay_string)
11698 (overlay_strings, recenter_overlay_lists)
11699 (adjust_overlays_for_insert, adjust_overlays_for_delete)

11704 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11705 (validate_region): Omit unnecessary test for b <= e,
11706 since that's guaranteed by the previous test.
11707 (adjust_overlays_for_delete): Avoid pos + length overflow.
11708 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11709 (report_overlay_modification):
11710 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11711 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11712 Omit pointer cast, which isn't needed anyway, and doesn't work
11713 after the EMACS_INT -> ptrdiff_t change.
11714 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11715 * buffer.h: Adjust decls to match defn changes elsewhere.
11716 (struct buffer_text, struct buffer):
11717 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11718 Use EMACS_INT, not int, where int might not be wide enough.
11719 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11720 not int, to avoid needless 32-bit limit on 64-bit hosts.
11721 (exec_byte_code): Use tighter memory-full test, one that checks
11722 for alloca overflow. Don't compute the address of the object just
11723 before an array, as that's not portable. Use EMACS_INT, not
11724 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11725 * callint.c (Fcall_interactively):
11726 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11727 * callproc.c (call_process_kill, Fcall_process):

11737 (Fupcase_word, Fdowncase_word, Fcapitalize_word):

11739 (casify_object): Avoid integer overflow when overallocating buffer.
11740 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11741 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

11743 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11744 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11745 integers are now checked earlier. All uses replaced with XINT.
11747 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11748 For CCL_MapSingle, check that content and value are in int range.
11749 (ccl_driver, Fregister_code_conversion_map):
11750 Check that Vcode_version_map_vector is a vector.
11751 (resolve_symbol_ccl_program): Check that vector header is in range.
11752 Always copy the vector, so that we can check its contents reliably
11753 now rather than having to recheck each instruction as it's being
11754 executed. Check that vector words fit in 'int'.
11755 (ccl_get_compiled_code, Fregister_ccl_program)
11756 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11757 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

11759 contents are in range.
11760 (Fccl_execute_on_string): Check that status is in range.

11762 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

11770 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11772 avoid mishandling large integers.

11783 Don't rely on undefined behavior with signed left shift overflow.
11784 Don't assume unsigned int fits into fixnum, or that fixnum fits
11785 into unsigned int. Don't require max_code to be a valid fixnum;
11786 that's not true for gb10830 4-byte on a 32-bit host. Allow
11787 invalid_code to be a cons, for the same reason. Require code_offset
11788 to be a character. Avoid int overflow if max_char is close
11790 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11791 this is intended anyway and avoids some undefined behavior.
11792 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11793 INDEX_TO_CODE_POINT, as that's what it expects.
11794 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11795 * charset.h (DECODE_CHAR): Return int, not unsigned;
11796 this is what was intended anyway, and it avoids undefined behavior.

11798 integer-overflow issues.
11799 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11800 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11801 where the argument is EMACS_INT, and this behavior is not intended.
11802 * chartab.c (Fmake_char_table, Fset_char_table_range)
11803 (uniprop_get_decoder, uniprop_get_encoder):
11804 Don't assume fixnum fits in int.
11805 * cmds.c (move_point): New function, that does the gist of
11806 Fforward_char and Fbackward_char, but does so while checking
11807 for integer overflow more accurately.
11808 (Fforward_char, Fbackward_char): Use it.
11809 (Fforward_line, Fend_of_line, internal_self_insert)

12413 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
12414 (handle_tool_bar_click):
12415 Use int, not unsigned, since we prefer signed and the signedness
12416 doesn't matter here.
12417 (get_next_display_element, next_element_from_display_vector):
12418 Use int, not EMACS_INT, when int is wide enough.
12419 (start_hourglass): Use duration_to_sec_usec to do proper
12420 overflow checking on durations.
12421 * xfaces.c (Fbitmap_spec_p):
12422 Check that fixnums are in proper range for system types.

12458 * xterm.c (x_x_to_emacs_modifiers):
12459 Don't assume EMACS_INT overflows nicely into int.
12460 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12461 may come from Lisp.
12462 (handle_one_xevent): NATNUMP can eval its arg twice.
12463 (x_connection_closed):
12464 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

12470 2012-05-25 Glenn Morris <rgm@gnu.org>
12472 * lisp.mk (lisp): Update for more files being compiled now.
12474 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12476 * lread.c: Remove `read_pure' which makes no difference.
12477 (read_pure): Remove var.
12478 (unreadpure): Remove function.
12479 (readevalloop): Don't call read_list with -1 flag.
12480 (read1, read_vector): Don't test read_pure any more.
12481 (read_list): Simplify.

12489 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12491 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12492 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12494 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12497 This directory predates autoconf and is no longer needed nowadays.
12498 Move its few remaining bits of functionality to where they're needed.
12499 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12500 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12501 * m/template.h: Remove.
12502 * Makefile.in (M_FILE): Remove. All uses removed.
12503 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12504 * lisp.h (USE_LSB_TAG):
12505 * mem-limits.h (EXCEEDS_LISP_PTR):
12506 Use VAL_MAX, not VALBITS, in #if.
12507 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12508 (EMACS_UINT): Define unconditionally now.
12509 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12510 (BITS_PER_EMACS_INT): New constants, replacing
12511 what used to be in config.h, but not useful in #if.
12512 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12513 define them any more.
12514 (VAL_MAX): New macro.
12516 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12517 BITS_PER_EMACS_INT, in #if.
12518 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12519 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12520 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12521 * s/ms-w32.h (DATA_START):
12522 Move here from removed file m/intel386.h.
12523 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12524 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12526 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12528 Assume C89 or later.
12529 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12530 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)

12549 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12551 2012-05-19 Ken Brown <kbrown@cornell.edu>
12553 * xfns.c (x_in_use): Remove `static' qualifier.
12554 * xterm.h (x_in_use): Declare.
12555 * xgselect.c: Include xterm.h.
12556 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12557 and `display_arg' (bug#9754).
12559 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12561 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12563 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12564 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12566 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12568 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12570 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12571 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12573 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12574 reference to image_cache->refcount.
12575 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12577 2012-05-17 Juri Linkov <juri@jurta.org>
12579 * search.c (Fword_search_regexp, Fword_search_backward)
12580 (Fword_search_forward, Fword_search_backward_lax)
12581 (Fword_search_forward_lax): Move functions to isearch.el
12582 (bug#10145, bug#11381).
12584 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12586 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12588 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12590 * lread.c (init_obarray): Declare Qt and Qnil as special.
12592 2012-05-14 Glenn Morris <rgm@gnu.org>
12594 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12595 Put "libexec" before "bin", for the sake of init_callproc_1.
12597 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12599 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12601 * unexaix.c: Port to more-recent AIX compilers.
12602 (report_error, report_error_1, make_hdr, copy_sym)
12603 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12604 Make arguments const char *, not char *, to avoid violations of C
12605 standard and to fix some AIX warnings reported by Gilles Pion.
12607 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12609 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12610 already have overlays loaded.
12611 (handle_single_display_spec): Before returning without displaying
12612 fringe bitmap, synchronize the bidi iterator with the main display
12613 iterator, by calling iterate_out_of_display_property.
12614 (iterate_out_of_display_property): Detect buffer iteration by
12615 testing that it->string is a Lisp string.
12616 (get_next_display_element): When the current object is exhausted,
12617 and there's something on it->stack, call set_iterator_to_next to
12618 proceed with what's on the stack, instead of returning zero.
12619 (set_iterator_to_next): If called at the end of a Lisp string,
12620 proceed to consider_string_end without incrementing string
12621 position. Don't increment display vector index past the end of
12622 the display vector. (Bug#11417)
12623 (pos_visible_p): Don't report a position visible when move_it_to
12624 stopped at the last line of window, which happens to be scanned
12625 backwards by the bidi iteration. (Bug#11464)
12627 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12629 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12630 and right-margin display specs even if the spec is invalid or we
12631 are on a TTY, and thus unable to display on the fringes.
12632 That's because the text with the property will not be displayed anyway,
12633 so we need to signal to the caller that this is a "replacing"
12634 display spec. This fixes display when the spec is invalid or we
12637 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12639 * unexaix.c (make_hdr): Fix typo in prototype.
12640 This bug broke the build on AIX. Problem reported by Gilles Pion.
12642 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12644 * keyboard.c (kbd_buffer_get_event): Read special events also in
12645 batch mode. (Bug#11415)
12647 2012-05-12 Glenn Morris <rgm@gnu.org>
12649 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12651 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12653 * lisp.mk (lisp): Add newcomment.elc.
12655 2012-05-12 Glenn Morris <rgm@gnu.org>
12657 * Makefile.in (MKDIR_P): New, set by configure.
12658 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12660 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12662 Remove unused function hourglass_started.
12663 * dispextern.h (hourglass_started):
12664 * w32fns.c (hourglass_started):
12665 * xdisp.c (hourglass_started): Remove.
12667 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12669 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12670 Update dependencies.
12672 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12674 * xgselect.c (xg_select): Put maxfds+1 into a var.
12675 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12677 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12679 2012-05-10 Dave Abrahams <dave@boostpro.com>
12681 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12682 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12684 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12686 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12687 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12688 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12689 Initialize xd_registered_buses.
12691 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12693 Untag more efficiently if USE_LSB_TAG.
12694 This is based on a proposal by YAMAMOTO Mitsuharu in
12695 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12696 For an admittedly artificial (nth 8000 longlist) benchmark on
12697 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12698 Emacs's overall text size by 1%.
12699 * lisp.h (XUNTAG): New macro.
12700 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12701 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12702 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12703 * eval.c (Fautoload):
12704 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12705 * frame.h (XFRAME): Use XUNTAG.
12707 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12708 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12709 Remove unportable assumptions about print widths of types like
12711 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12712 intptr_t when converting between pointer and integer, to avoid GCC
12713 warnings about wrong width.
12715 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12717 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12718 stack for each reader_thread, instead of defaulting to 8MB
12719 determined by the linker. This avoids failures in creating
12720 subprocesses on Windows 7, see the discussion in this thread:
12721 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12723 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12725 Fix up display of the *Minibuf-0* buffer in the mini window.
12726 * keyboard.c (read_char): Don't clear the echo area if there's no
12728 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12729 contents of *Minibuf-0*) if there's no message displayed in its stead.
12731 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12733 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12736 2012-05-06 Chong Yidong <cyd@gnu.org>
12738 * lisp.mk (lisp): Update.
12740 2012-05-05 Jim Meyering <meyering@redhat.com>
12742 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12744 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12746 * data.c (PUT_ERROR): New macro.
12747 (syms_of_data): Use it. Add new error type `user-error'.
12748 * undo.c (user_error): New function.
12749 (Fprimitive_undo): Use it.
12750 * print.c (print_error_message): Adjust print style for `user-error'.
12751 * keyboard.c (user_error): New function.
12752 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12754 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12756 Do not limit current-time-string to years 1000..9999.
12757 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12758 (Fcurrent_time_string): Support any year that is supported by the
12759 underlying localtime representation. Don't use asctime, as it
12760 has undefined behavior for years outside the range -999..9999.
12762 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12764 Fix race conditions involving setenv, gmtime, localtime, asctime.
12765 Without this fix, interrupts could mess up code that uses these
12766 nonreentrant functions, since setting TZ invalidates existing
12767 tm_zone or tzname values, and since most of these functions return
12768 pointers to static storage.
12769 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12770 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12771 Grow the critical sections to include not just invoking
12772 localtime/gmtime, but also accessing these functions' results
12773 including their tm_zone values if any, and any related TZ setting.
12774 (format_time_string): Last arg is now struct tm *, not struct tm **,
12775 so that the struct tm is saved in the critical section.
12776 All callers changed. Simplify allocation of initial buffer, partly
12777 motivated by the fact that memory allocation needs to be outside
12778 the critical section.
12780 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12782 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12783 with RESET_INTERVAL.
12785 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12786 Remove duplicated buffer name initialization.
12788 2012-05-02 Jim Meyering <jim@meyering.net>
12790 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12792 * xfns.c (x_window): Use xstrdup (Bug#11375).
12794 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12796 * xdisp.c (pos_visible_p): If already at a newline from the
12797 display string before the 'while' loop, don't walk back the glyphs
12798 from it3.glyph_row. Solves assertion violation when the display
12799 string begins with a newline (egg.el). (Bug#11367)
12801 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12803 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12806 2012-05-01 Glenn Morris <rgm@gnu.org>
12808 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12809 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12810 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12811 All were removed before 23.1.
12813 * dispnew.c: Remove HAVE_LIBNCURSES test;
12814 it is always true on relevant platforms.
12816 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12817 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

12829 Do not avoid creating empty evaporating overlays (Bug#9642).
12830 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12831 That is, do not delete an evaporating overlay if it becomes
12832 empty after its bounds are adjusted to fit within its buffer.
12833 This fix caused other problems, and I'm reverting it until we get
12834 to the bottom of them.
12836 2012-04-27 Chong Yidong <cyd@gnu.org>
12838 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12840 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12842 * xdisp.c (pos_visible_p): If the window start position is beyond
12843 ZV, start the display from buffer beginning. Prevents assertion
12844 violation in init_iterator when the minibuffer window is scrolled
12845 via the scroll bar.
12847 * window.c (window_scroll_pixel_based): Likewise.
12849 2012-04-27 Chong Yidong <cyd@gnu.org>

12856 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12858 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12860 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12861 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12863 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12865 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12866 display element, check also the underlying string or buffer
12867 character. (Bug#11341)
12869 * w32menu.c: Include w32heap.h.
12870 (add_menu_item): If the call to AppendMenuW (via
12871 unicode_append_menu) fails, disable Unicode menus only if we are
12872 running on Windows 9X/Me.
12874 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12876 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12877 (xgetint): Add missing shift for LSB tags.
12879 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12881 * keyboard.c (read_char): Don't wipe echo area for select window

12887 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12888 manipulation of :loaded-from data.
12890 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12892 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12893 now a cons (bug#11311).
12895 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12897 Do not create empty overlays with the evaporate property (Bug#9642).
12898 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12899 if it becomes empty after its bounds are adjusted to fit within
12900 its buffer. Without this fix, in a nonempty buffer (let ((o
12901 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12902 yields an empty overlay that has the evaporate property, which is
12903 not supposed to happen.
12905 Fix minor GTK3 problems found by static checking.
12906 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12907 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)

12926 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12927 (__malloc_size_t, __malloc_ptrdiff_t):
12928 Remove. All uses removed, replaced by the definiens if needed,
12929 since we can assume C89 or better now.

12947 Omit no-longer-needed casts.
12948 (valloc): Use getpagesize, not __getpagesize.
12949 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

13018 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13020 * sysdep.c [__FreeBSD__]: Minor cleanups.
13021 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13022 Use Emacs indenting style more consistently. Avoid some casts.
13023 Use 'double' consistently rather than mixing 'float' and 'double'.
13025 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13027 * sysdep.c (list_system_processes, system_process_attributes):
13028 Add implementation for FreeBSD (Bug#5243).

13034 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13036 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13037 It is never used otherwise.
13039 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13041 * print.c (print_preprocess): Only check print_depth if print-circle
13043 (print_object): Check for cycles even when print-circle is nil and

13048 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13049 set the status to "failed" and ensure that sentinel is run.
13051 2012-04-20 Glenn Morris <rgm@gnu.org>
13053 * process.c (Fset_process_inherit_coding_system_flag)
13054 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13064 farther than the first row after the header line, if any.
13065 Don't consider the header-line row as "partially visible", even if

13104 New extern decls, to avoid calling undeclared functions.
13105 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13106 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13107 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13108 (NEED_MEM_INSERT): New macro.
13109 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13110 Remove one incorrect comment and fix another.

13116 (r_alloc_sbrk): Now static.
13118 Improve ralloc.c interface checking.
13119 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13120 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

13127 * alloc.c (which_symbols): Fix alignment issue / type clash.
13129 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13131 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13132 (struct Lisp_Misc_Any): Likewise.
13133 (struct Lisp_Free): Likewise.

13146 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13147 * s/netbsd.h, s/sol2-6.h:
13148 Remove definition of GC_MARK_STACK, since the default now works.
13149 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13150 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13151 no longer the default.
13152 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13154 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13156 * lread.c (lisp_file_lexically_bound_p):

13166 * nsterm.m (constrainFrameRect): Always constrain when there is only
13167 one screen (Bug#10962).

13177 2012-04-11 Daniel Colascione <dancol@dancol.org>
13179 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13180 against is gone. It's better to use vfork now so that when Cygwin
13181 gains a new, working vfork, we use it automatically (bug#10398).
13183 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13203 * w32.c (w32_delayed_load): Record the full path of the library
13204 being loaded (bug#10424).
13206 2012-04-09 Glenn Morris <rgm@gnu.org>
13208 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13209 not just in the obarray, before snarfing them. (Bug#11036)

13217 * process.h: Add integer `gnutls_handshakes_tried' member to
13220 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
13221 Add convenience `GNUTLS_LOG2i' macro.
13223 * gnutls.c (gnutls_log_function2i): Convenience log function.
13224 (emacs_gnutls_read): Use new log functions,
13225 `gnutls_handshakes_tried' process member, and
13226 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13227 attempts per process (connection).
13229 2012-04-09 Chong Yidong <cyd@gnu.org>
13231 * eval.c (Fuser_variable_p, user_variable_p_eh)
13232 (lisp_indirect_variable): Functions deleted.
13233 (Fdefvar): Caller changed.
13235 * callint.c (Finteractive, Fcall_interactively):
13236 * minibuf.c (Fread_variable): Callers changed.
13238 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13240 * xdisp.c (set_cursor_from_row): If the display string appears in
13241 the buffer at position that is closer to point than the position
13242 after the display string, display the cursor on the first glyph of
13243 the display string. Fixes cursor display when a 'display' text
13244 property immediately follows invisible text. (Bug#11094)
13246 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13248 composite.c: use 'double' consistently
13249 * composite.c (get_composition_id): Use 'double' consistently
13250 instead of converting 'float' to 'double' and vice versa; this is
13251 easier to understand and avoids a GCC warning.
13253 2012-04-09 Glenn Morris <rgm@gnu.org>

13278 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13279 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13280 objects, as mark_maybe_pointer will catch them otherwise.
13281 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13282 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13301 (init_libxml2_functions, libxml2_loaded_p): New functions.
13302 (parse_region): Call fn_xmlCheckVersion instead of using the macro

13305 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13307 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13308 Call init_libxml2_functions before calling libxml2 functions.
13309 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13311 * emacs.c: Don't include libxml/parser.h.
13312 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13313 xmlCleanupParser directly.
13315 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13317 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13319 * indent.c (Fvertical_motion): If there is a display string at
13320 point, use it.vpos to compute how many lines to backtrack after

13323 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13325 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13326 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13327 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13328 macros related to unification of CJK characters. For the details,
13329 see the discussion following the message here:
13330 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13332 2012-04-04 Chong Yidong <cyd@gnu.org>
13334 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13336 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13338 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13339 instead of alloca. (Bug#11138)
13341 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

13346 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13348 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13349 position we get to after a call to move_it_to fails the
13350 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13351 only if we wind up in a string from display property. (Bug#11063)
13353 * window.c (Fdelete_other_windows_internal): Invalidate the row
13354 and column information about mouse highlight, so that redisplay
13355 restores it after reallocating the glyph matrices. (Bug#7464)
13357 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13358 string comes from a `display' text property, use the buffer
13359 position of that property as if we actually saw that position in
13361 (move_it_by_lines): Remove the assertion that
13362 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13363 violated when there's a before-string at the beginning of a line.
13366 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13368 * xdisp.c (append_space_for_newline): If the default face was
13369 remapped, use the remapped face for the appended newline.
13370 (extend_face_to_end_of_line): Use the remapped default face for
13371 extending the face to the end of the line.
13372 (display_line): Call extend_face_to_end_of_line when the default
13373 face was remapped. (Bug#11068)
13375 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13377 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

13401 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13403 2012-03-25 Kenichi Handa <handa@m17n.org>
13405 * dispextern.h (struct glyph): Change the bit length of
13406 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13408 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13410 * s/ms-w32.h (tzname): Include time.h before redirecting to
13411 _tzname. Fixes the MSVC build. (Bug#9960)
13413 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13415 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13418 * xterm.c (XTread_socket): Only modify handling_signal if
13419 !SYNC_INPUT. (Bug#11080)
13421 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13423 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13424 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13425 when fetching a multibyte character consumes more bytes than
13426 CHAR_BYTES returns, due to unification of CJK characters in
13427 string_char. (Bug#11073)
13429 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13431 * process.c (wait_reading_process_output): Handle pty disconnect
13432 by refraining from sending oneself a SIGCHLD (bug#10933).

13460 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13461 it fit in a valid range (Bug#11003).
13463 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13465 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13466 that is not from display property, accept the row as a "cursor
13467 row" if one of the string's character has a non-nil `cursor'
13468 property. Fixes cursor positioning when there are newlines in
13469 overlay strings, e.g. in icomplete.el. (Bug#11035)
13471 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13473 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13475 2012-03-12 Chong Yidong <cyd@gnu.org>
13477 * eval.c (inhibit_lisp_code): Rename from
13478 inhibit_window_configuration_change_hook; move from window.c.
13480 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13481 * window.c (run_window_configuration_change_hook)
13482 (syms_of_window): Callers changed.

13502 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13505 2012-03-03 Glenn Morris <rgm@gnu.org>
13507 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13509 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13511 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13512 position past the first glyph_row that ends at ZV. (Bug#10902)
13513 (redisplay_window, next_element_from_string): Fix typos in
13515 (redisplay_window): Pass to move_it_vertically the margin in
13516 pixels, not in screen lines.
13518 2012-03-02 Glenn Morris <rgm@gnu.org>
13520 * buffer.c (buffer-list-update-hook): Doc fix.
13522 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13524 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13525 push_it before setting up the iterator for the first overlay
13526 string, even if we have an empty string loaded.
13527 (next_overlay_string): If there's an empty string on the iterator
13528 stack, pop the stack. (Bug#10903)
13530 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13532 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13533 Suggested by Stefan Monnier in
13534 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13535 * alloc.c (widen_to_Lisp_Object): New static function.
13536 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13537 and widening them to Lisp_Objects. This would work even if
13538 USE_LSB_TAG is defined and wide integers are used, which might
13539 happen in a future version of Emacs.
13541 2012-02-25 Chong Yidong <cyd@gnu.org>
13543 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

13548 before saving to clipboard manager.
13550 2012-02-24 Chong Yidong <cyd@gnu.org>
13552 * keyboard.c (process_special_events): Handle all X selection
13553 requests in kbd_buffer, not just the next one (Bug#8869).
13555 2012-02-23 Chong Yidong <cyd@gnu.org>
13557 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13558 call when setting menu-bar-lines and tool-bar-lines parameters.
13559 (unwind_create_frame_1): New helper function.

13580 when computing $valmask.
13582 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13583 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13584 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13585 It's useless in that case, and it can cause problems on hosts
13586 that allocate halves of EMACS_INT values separately.
13587 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13588 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13589 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13590 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13591 it avoids undefined behavior on hosts where shifting right by more
13592 than the word width has undefined behavior.
13594 2012-02-19 Chong Yidong <cyd@gnu.org>
13596 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13597 (Funhandled_file_name_directory, Ffile_name_as_directory)

13616 2012-02-15 Chong Yidong <cyd@gnu.org>
13618 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

13634 2012-02-12 Chong Yidong <cyd@gnu.org>
13636 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13637 as that creates a dangerous corner case.
13639 * window.c (Fdelete_window_internal): Invalidate the mouse
13640 highlight (Bug#9904).
13642 2012-02-12 Glenn Morris <rgm@gnu.org>

13645 (Fx_get_selection_internal, Fx_disown_selection_internal)
13646 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13647 * nsselect.m (Fx_own_selection_internal)
13648 (Fx_disown_selection_internal, Fx_selection_exists_p)
13649 (Fx_selection_owner_p, Fx_get_selection_internal):
13650 Sync docs and argument specs with the xselect.c versions.
13652 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13654 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

13672 2012-02-07 Chong Yidong <cyd@gnu.org>
13674 * buffer.c (Fbuffer_local_variables)
13675 (buffer_lisp_local_variables): Handle unbound vars correctly;
13676 don't let Qunbound leak into Lisp.
13678 2012-02-07 Glenn Morris <rgm@gnu.org>
13680 * image.c (Fimagemagick_types): Doc fix.
13682 * image.c (imagemagick-render-type): Change it from a lisp object
13683 to an integer. Move the doc here from the lisp manual.

13712 * keyboard.c (adjust_point_for_property): Don't position point
13713 before BEGV. (Bug#10696)
13715 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13717 Handle overflow when computing char display width (Bug#9496).
13718 * character.c (char_width): Return EMACS_INT, not int.
13719 (char_width, c_string_width): Check for overflow when
13720 computing the width; this is possible now that individual
13721 characters can have unbounded width. Problem introduced
13722 by merge from Emacs 23 on 2012-01-19.
13724 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

14257 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
14258 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
14259 this macro definition.
14261 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

14286 * xdisp.c (redisplay_window): If cursor row is not fully visible
14287 after recentering, and scroll-conservatively is set to a large
14288 number, scroll window by a few more lines to make the cursor fully
14289 visible and out of scroll-margin. (Bug#10105)
14290 (start_display): Don't move to the next line if the display should
14291 start at a newline that is part of a display vector or an overlay
14292 string. (Bug#10119)

14371 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14372 Otherwise, valgrind does not work on some platforms.
14373 Problem reported by Andreas Schwab in
14374 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14375 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14376 is set, removing the need for VIRT_ADDRESS_VARIES.
14377 (PURE_P): Use a more-efficient implementation that needs just one
14378 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14379 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14380 to 4 (xorl, subq, cmpq, setbe).
14381 * alloc.c (pure): Always extern now, since that's the
14382 VIRT_ADDR_VARIES behavior.
14383 (PURE_POINTER_P): Use a single comparison, not two, for
14384 consistency with the new puresize.h.
14385 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14386 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
14387 Remove VIRT_ADDR_VARIES no longer needed.

14392 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14393 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14394 behave as if the cursor position were at the window margin.
14396 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14397 and the cursor position is out of bounds, behave as if the cursor
14398 position were at the window margin. (Bug#10075)
14400 2011-11-18 Chong Yidong <cyd@gnu.org>
14402 * window.c (Fwindow_combination_limit): Make first argument
14403 non-optional, since it is meaningless for live windows like the

14417 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
14418 hash values of the two rows.
14419 (copy_row_except_pointers): Preserve the used[] arrays and the
14420 hash values of the two rows. (Bug#10035)
14421 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14423 * xdisp.c (row_hash): New function, body extracted from
14424 compute_line_metrics.
14425 (compute_line_metrics): Call row_hash, instead of computing the
14428 * dispnew.c (verify_row_hash): Call row_hash for computing the
14429 hash code of a row, instead of duplicating code from xdisp.c.
14431 * dispextern.h (row_hash): Add prototype.
14433 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14435 * frame.c (delete_frame): Don't delete the terminal when the last
14436 X frame is closed if emacs is built with GTK toolkit.

14460 (recombine_windows, make_parent_window, make_window)
14461 (Fsplit_window_internal, saved_window)
14462 (Fset_window_configuration, save_window_save): Rename all
14463 occurrences of window_nest to window_combination_limit.
14465 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
14467 * image.c (imagemagick_load_image): Fix typo.
14469 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14471 * xdisp.c (display_line): Move the call to
14472 highlight_trailing_whitespace before the call to
14473 compute_line_metrics, since the latter needs to see the final
14474 faces of all the glyphs to compute ROW's hash value.
14475 Fixes assertion violations in row_equal_p. (Bug#10035)
14477 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14479 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14480 just return (bug#10044).
14482 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14484 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14485 with user-defined heap size. Bump the default size of the temacs
14486 heap to 27MB, to avoid memory warning when running temacs.
14487 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
14489 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14490 current_matrix and desired_matrix. (Bug#9990)
14491 (verify_row_hash) [XASSERTS]: New function.
14492 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
14493 that the hash value of glyph rows is correct.

14522 2011-11-11 Johan Bockgård <bojohan@gnu.org>
14524 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
14525 avoid a crash (bug#9496).
14527 2011-11-09 Chong Yidong <cyd@gnu.org>
14529 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

14536 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14538 Avoid some portability problems by eschewing 'extern inline' functions.
14539 The trivial performance wins aren't worth the portability hassles; see
14540 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14542 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14543 (window_box_width, window_box_left, window_box_left_offset)
14544 (window_box_right, window_box_right_offset): Undo previous change,
14545 by removing the "extern"s.
14546 * intervals.c (adjust_intervals_for_insertion)
14547 (adjust_intervals_for_deletion): Undo previous change,
14548 making these static again.
14549 (offset_intervals, temp_set_point_both, temp_set_point)
14550 (copy_intervals_to_string): No longer inline.
14551 * xdisp.c (window_text_bottom_y, window_box_width)

14582 (delete_all_subwindows): Rename to delete_all_child_windows.
14583 (Fdelete_other_windows_internal, Fset_window_configuration):
14584 Call delete_all_child_windows instead of delete_all_subwindows.

14588 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
14590 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14591 This is also needed for porting to any host where GC_MARK_STACK is
14592 not GC_MAKE_GCPROS_NOOPS.
14593 (which_symbols): Use it.
14595 2011-11-07 Kenichi Handa <handa@m17n.org>
14597 * coding.c (coding_set_destination): Check coding->src_pos only
14598 when coding->src_object is a buffer (bug#9910).

14608 * xmenu.c (cleanup_widget_value_tree): New function.
14609 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14610 calling free_menubar_widget_value_tree directly (Bug#9830).
14612 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14614 Fix some portability problems with 'inline'.
14615 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14616 (window_box_width, window_box_left, window_box_left_offset)
14617 (window_box_right, window_box_right_offset): Declare extern.
14618 Otherwise, these inline functions do not conform to C99 and
14619 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14620 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14621 * intervals.c (adjust_intervals_for_insertion)
14622 (adjust_intervals_for_deletion): Now extern, because otherwise the
14623 extern inline functions 'offset_intervals' couldn't refer to it.
14624 (static_offset_intervals): Remove.
14625 (offset_intervals): Rewrite using the old contents of
14626 static_offset_intervals. The old version didn't conform to C99
14627 because an extern inline function contained a reference to an
14628 identifier with static linkage.

14649 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
14650 (Fwindow_vscroll): Doc fix.
14651 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14652 argument, since it makes no sense to pass a live window and for
14653 consistency with window-child.

14774 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14775 past the beginning of the current glyph matrix.

14826 Not clear what it was for, and it causes various bugs. (Bug#9839)
14828 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14830 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

14850 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14852 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14853 <oslsachem@gmail.com> for helping to debug this.
14855 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

14861 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14863 (w32font_open_internal, compute_metrics):
14864 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14865 instead of calling the "wide" APIs directly.
14867 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14869 * w32.h (syms_of_w32font): Add prototype.
14871 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

14875 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14876 (Fmove_to_window_line): Doc fix.
14878 2011-10-27 Chong Yidong <cyd@gnu.org>
14880 * process.c (make_process): Set gnutls_state to NULL.
14882 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14883 non-NULL, regardless of GNUTLS_INITSTAGE.
14884 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

14911 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14913 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14915 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14917 * keyboard.c (test_undefined): New function (bug#9751).
14918 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14920 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14922 * sysdep.c (init_sys_modes): Fix the check for the controlling
14923 terminal (Bug#6649).
14925 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14927 * dispextern.h (struct bidi_it): New member next_en_type.
14929 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14930 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14931 current character, check also for next_en_type being WEAK_EN.
14932 (bidi_resolve_weak): Don't enter the expensive loop if the current
14933 position is before next_en_pos. Record the bidi type of the first
14934 non-ET, non-BN character we find, in addition to its position.
14935 (bidi_level_of_next_char): Invalidate next_en_type when
14936 next_en_pos is over-stepped.
14938 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14940 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14941 * editfns.c: Rewrite current-time-zone so that it invokes
14942 the equivalent of (format-time-string "%Z") to get the time zone name.
14943 This fixes a bug when the time zone name contains characters that
14944 need converting from the system time locale to Emacs internal format.
14945 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14946 that patch fixed format-time-string to do the conversion, but
14947 I forgot to fix current-time-zone.
14948 (format_time_string): New function, containing most of
14949 what Fformat_time_string used to contain.
14950 (Fformat_time_string): Rewrite in terms of format_time_string.
14951 This doesn't change this function's behavior.
14952 (current-time-zone): Rewrite to use format_time_string.
14953 This fixes the bug reported by Michael Schierl in
14954 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14955 Jason Rumney's 2007-06-07 change worked around this bug, but
14957 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14959 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14961 * xdisp.c (start_display): If the character at POS is displayed
14962 via a display vector, reset IT->current.dpvec_index to zero.
14963 (try_window_reusing_current_matrix): If a line ends in a display
14964 vector or the next line starts in a display vector, continue
14965 redrawing the window even though the character position of
14966 start_row was reached.
14969 2011-10-18 Chong Yidong <cyd@gnu.org>
14971 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14972 with nobreak-char-display too.
14974 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14976 Fix part 3 of bug#9771.
14977 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14978 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14979 non-neutral characters if the current character is a paragraph
14980 separator (a.k.a. Newline). This avoids running the same
14981 expensive loop twice, once when we consume the preceding newline
14982 and the other time when the line actually needs to be displayed.
14983 Avoid the loop when we see neutrals on the base embedding level
14984 following a character whose directionality is the same as the
14985 paragraph's. This avoids running the expensive loop when a line
14986 ends in a long sequence of neutrals, like control characters.
14987 Add assertion against STRONG_AL type. Slightly rearrange code
14988 that determines the type of a neutral given the first non-neutral
14990 (bidi_level_of_next_char): Set next_en_pos to zero when
14991 invalidating its info.
14993 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14995 * xdisp.c (push_display_prop): Determine whether to record string
14996 or buffer position by IT->string, not by IT->method. Allow
14997 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14998 (move_it_vertically_backward): Don't look for character position
14999 immediately after the newline when in a continuation line.
15002 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15004 * window.c (coordinates_in_window): Rewrite and delabelize
15005 vertical border check. (Bug#5357) (Bug#9618)
15007 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15009 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15010 errors in XSetWindowBorder (bug#9310).
15012 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15014 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15015 avoid crash when xmalloc overrun checking is enabled.
15017 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15019 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15020 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15021 cursor motion with <left> and <right> arrow keys.
15023 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15024 some callers set that themselves.
15026 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15028 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15029 display string and the previous row comes from the same string and
15030 is empty. (Bug#9739) (Bug#9738)
15032 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15034 * doc.c (get_doc_string): Encode file name (bug#9735).
15036 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15038 * bidi.c (bidi_level_of_next_char):
15039 * xdisp.c (get_visually_first_element): Remove old incorrect
15040 comments regarding the Unicode Line Separator character.
15042 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15044 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15046 * alloc.c (Fgc_status): Do not access beyond zombies array
15047 boundary if nzombies > MAX_ZOMBIES.
15048 * alloc.c (dump_zombies): Add missing format specifier.
15050 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15052 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15053 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15055 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15056 Some packages use them to denote characters with modifiers.
15058 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15060 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15061 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15062 matching a pp-number. Rename parameter var to var1.
15064 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15066 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15068 2011-10-08 Glenn Morris <rgm@gnu.org>
15070 * callint.c (Fcall_interactively): Give a more explicit error for the
15071 'c' case with a non-character input. (Bug#8479)
15073 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15075 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15077 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15078 lines that are hscrolled on the left.

15081 presence of header-line. (Bug#4426)
15083 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15085 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15086 Don't advertise functionality which we discourage or doesn't work.
15088 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15090 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15091 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15092 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15093 this makes Emacs dump core during garbage collection on rare
15094 occasions. sizeof is obviously inferior to offsetof here, so
15095 stick with offsetof.
15096 (GC_POINTER_ALIGNMENT): New macro.
15097 (mark_memory): Omit 3rd (offset) arg; caller changed.
15098 Don't assume EMACS_INT alignment is the same as pointer alignment.
15100 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15102 * keyboard.c (read_key_sequence_remapped): New var.
15103 (read_key_sequence): Compute remapping in the right buffer.
15104 (command_loop_1): Use read_key_sequence's remapping directly.
15106 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15108 * dired.c (file_name_completion): Don't expand file name.
15109 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15110 before checking file name handler.
15112 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15113 they've been requested explicitly (bug#9591).
15115 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15117 * keymap.c (Fsingle_key_description): Use make_specified_string
15118 instead of build_string to build string from push_key_description.
15121 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15123 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15124 This fixes a Y2038 bug on 64-bit hosts.
15125 * buffer.c (reset_buffer):
15126 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15127 (Fclear_buffer_auto_save_failure):
15128 Use 0, not -1, to represent an unset failure time, since time_t
15129 might not be signed.
15131 Remove dependency on glibc malloc internals.
15132 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15133 Move back here from lisp.h, but with their new implementations.
15134 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15135 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15136 * charset.c (charset_table_init): New static var.
15137 (syms_of_charset): Use it instead of xmalloc. This removes a
15138 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15139 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15140 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15141 Move back to alloc.c.
15142 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15143 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15145 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15147 * nsterm.m (windowDidResize): Call x_set_window_size only when
15148 ns_in_resize is true. Otherwise set pixelwidth/height and
15149 call change_frame_size (Bug#9628).
15151 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15153 Port --enable-checking=all to Fedora 14 x86-64.
15154 * charset.c (syms_of_charset): Also account for glibc malloc's
15155 internal overhead when calculating the initial malloc maximum.
15157 Port --enable-checking=all to Fedora 14 x86.
15158 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15160 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15161 (overrun_check_realloc, overrun_check_free):
15162 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15163 That way, xmalloc returns a properly-aligned pointer even if
15164 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15165 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15166 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15167 into account when calculating the initial malloc maximum.
15168 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15169 Move here from alloc.c, so that charset.c can use it too.
15170 Properly align; the old code wasn't right for common 32-bit hosts
15171 when configured with --enable-checking=all.
15172 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15173 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15175 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15177 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15180 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15182 * xdisp.c (compute_display_string_end): If there's no display
15183 string at CHARPOS, return -1.
15185 * bidi.c (bidi_fetch_char): When compute_display_string_end
15186 returns a negative value, treat the character as a normal
15187 character not covered by a display string. (Bug#9624)
15189 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15191 * lread.c (Fread_from_string): Fix typo in docstring.
15193 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15195 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15196 newline, reseat the iterator instead of bidi-iterating there one
15197 character at a time. (Bug#9610)
15198 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15199 TO_CHARPOS if the bidi iterator is at base embedding level.
15201 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15203 * lread.c (readevalloop): Use correct code for NBSP.
15204 (read1): Likewise. (Bug#9608)
15206 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15208 * dbusbind.c (Fdbus_register_signal): When service is not
15209 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15211 2011-09-25 Glenn Morris <rgm@gnu.org>
15213 * buffer.c (truncate-lines): Doc fix.
15215 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15217 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15218 (Fset_window_next_buffers): Doc fix.
15220 2011-09-24 Glenn Morris <rgm@gnu.org>
15222 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15224 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15226 Fix minor problems found by static checking.
15227 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15228 * indent.c (Fvertical_motion): Fix == vs = typo.
15230 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15232 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15233 Default value is now t. Doc fix.
15235 * indent.c (Fvertical_motion): Compute and apply the overshoot
15236 logic when moving up, not only when moving down. Fix the
15237 confusing name and values of the it_overshoot_expected variable;
15238 logic changes accordingly. (Bug#9254) (Bug#9549)
15240 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15241 CHARPOS is covered by a display string which includes newlines.
15242 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15243 is covered by a display string with embedded newlines.
15245 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15247 * dbusbind.c (Fdbus_register_signal): Add match rule to
15248 Vdbus_registered_objects_table. (Bug#9581)
15249 (Fdbus_register_method, Vdbus_registered_objects_table):
15252 2011-09-24 Jim Meyering <meyering@redhat.com>
15254 do not ignore write error for any output size
15255 The previous change was incomplete.
15256 While it makes emacs --batch detect the vast majority of stdout
15257 write failures, errors were still ignored whenever the output size is
15258 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15259 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15260 && echo FAIL: ignored write error
15261 FAIL: ignored write error
15262 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15263 && echo FAIL: ignored write error
15264 FAIL: ignored write error
15265 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15267 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15269 * emacs.c (Fkill_emacs): In noninteractive mode exit
15270 non-successfully if a write error occurred on stdout. (Bug#9574)
15272 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15274 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15277 * dispextern.h (struct it): Update the comment documenting what
15280 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15282 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15283 a display string, extend search for cursor position to end of row.
15284 (find_row_edges): If the row ends in a newline from a display
15285 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15286 Handle the case of a display string with multiple newlines.
15287 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15288 non-empty line. Fixes confusing cursor motion with arrow keys at
15289 the beginning of a line that starts with whitespace.
15291 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15293 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15296 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15298 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15299 boolean (Bug#9154).
15301 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15303 * xdisp.c (display_line): Record maximum and minimum buffer
15304 positions even if no glyphs were produced (e.g., by a zero-width
15305 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15306 buffer positions that will be removed from the glyph row because
15308 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15309 column is beyond frame width: don't subtract 1 "pixel" when
15310 computing width of the stretch.
15311 (reseat_at_next_visible_line_start): Undo the change made on
15312 2011-09-17 that saved paragraph information and restored it after
15313 the call to `reseat'. (Bug#9545)
15315 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15317 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15318 and turn window cursor on if cleared (Bug#9415).
15320 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15322 * search.c (boyer_moore): Take unibyte characters from pattern
15323 literally. (Bug#9458)
15325 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15327 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15329 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15331 Fix minor problem found by static checking.
15332 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15333 initialized, to pacify gcc -Wuninitialized.
15335 * fileio.c: Report proper errno when syscall falls.
15336 (Finsert_file_contents): Save and restore errno,
15337 so that report_file_error outputs the correct diagnostic.
15338 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15340 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15342 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15344 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15346 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15347 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15349 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15351 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15352 about the current paragraph and restore it after the call to reseat.
15354 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15355 (bidi_find_paragraph_start): Search back for paragraph beginning
15356 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15357 (bidi_move_to_visually_next): Only trigger paragraph-related
15358 computations when the last character is a newline or at EOB, not
15359 just any NEUTRAL_B. (Bug#9470)
15361 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15362 truncated lines if point is covered by a display string. (Bug#9524)
15364 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15366 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15367 (cons_to_x_long): New function.
15368 (lisp_data_to_selection_data): Use it. Correct the test for
15369 short-versus-long data; it was negated. Break out of vector
15370 loop, for efficiency, when a long datum is discovered.
15372 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15374 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15376 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15378 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15379 GCC PR/17406) by declaring this function with external scope.
15381 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15383 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15384 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15386 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15388 * editfns.c (Fformat): Correctly handle text properties on "%%".

15396 * xdisp.c (get_next_display_element)
15397 (fill_composite_glyph_string): Add comments about special meaning
15398 of TAB characters in a composition.
15400 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15402 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15403 This occurs when processing a multibyte format.
15404 Problem reported by Wolfgang Jenker.
15406 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15408 * xdisp.c (try_cursor_movement): Only check for exact match if
15409 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15411 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15413 Remove unused external symbols.
15414 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15415 * xdisp.c (calc_pixel_width_or_height): Now static.
15416 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15417 * indent.c (check_display_width):
15418 * w32term.c: Fix comment to match code.
15419 * xterm.c, xterm.h (x_catching_errors): Remove.
15421 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15423 * xselect.c: Use signed conversions more consistently (Bug#9498).
15424 (selection_data_to_lisp_data): Assume incoming selection data are
15425 signed integers, not unsigned. This is to be consistent with
15426 outgoing selection data, which was modified to use signed integers
15427 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15428 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15429 expects long, not unsigned long.
15431 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15433 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15434 computation of loop end. Reported by Johan Bockgård
15437 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15439 * frame.c (Fother_visible_frames_p): Function deleted.
15441 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15443 * indent.c (compute_motion): Process display vector front to back
15444 rather than the other way around. (Bug#2496)
15446 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15448 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15450 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15452 * minibuf.c (Fread_from_minibuffer): Doc fix.
15454 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15456 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15457 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15459 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15461 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15462 value for non-existent files.
15464 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15466 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15467 set its "size" to -1. This will set the modtime_size field of
15468 the corresponding buffer to -1, which is what
15469 verify-visited-file-modtime expects for files that do not exist.
15472 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15474 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15476 * lisp.h: ... from here. push_key_description is no longer
15477 defined in keyboard.c, so its declaration should not be in
15478 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15479 logically belongs with push_key_description.
15481 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15483 * buffer.h: Include <sys/types.h> instead of <time.h>.
15484 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15485 Problem reported by Herbert J. Skuhra.
15487 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15489 * xml.c (parse_region): Make the parsing work for
15490 non-comment-starting XML files again (bug#9144).
15492 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15494 * image.c (gif_load): Fix calculation of bottom and right corner.
15497 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15499 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15500 redisplay in small windows.
15502 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15504 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15506 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15508 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15509 Operate on live windows only.
15511 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15513 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15515 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15517 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15518 only under bidi iteration.
15520 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15522 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15524 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15526 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15527 Without this fix, the command to link temacs failed due to an
15528 undefined symbol __builtin_isnan. This is because
15529 /usr/include/iso/math_c99.h #defines isnan(x) to
15530 __builtin_isnan(x), but the bundled gcc, which identifies itself
15531 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15533 * floatfns.c (isnan): #undef, and then #define to a clone of
15535 (Fisnan): Always define, since it's always available now.
15536 (syms_of_floatfns): Always define isnan at the Lisp level.
15538 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15540 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15542 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15544 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15545 The previous code assumed that file offsets (off_t values) fit in
15546 EMACS_INT variables, which is not true on typical 32-bit hosts.
15547 The code messed up by falsely reporting buffer overflow in cases
15548 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15549 when "big" contains more than 2**29 bytes, even though this
15550 inserts just one byte and does not overflow the buffer.
15551 (Finsert_file_contents): Store file offsets as off_t
15552 values, not as EMACS_INT values. Check for overflow when
15553 converting between EMACS_INT and off_t. When checking for
15554 buffer overflow or for overlap, take the offsets into account.
15555 Don't use EMACS_INT for small values where int suffices.
15556 When checking for overlap, fix a typo: ZV was used where
15557 ZV_BYTE was intended.
15558 (Fwrite_region): Don't assume off_t fits into 'long'.
15559 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15561 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15563 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15565 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15567 sprintf-related integer and memory overflow issues (Bug#9412).
15569 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15570 (esprintf, exprintf, evxprintf): New functions.
15571 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15572 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15573 (modify_event_symbol): Do not assume that the length of
15574 name_alist_or_stem is safe to alloca and fits in int.
15575 (Fexecute_extended_command): Likewise for function name and binding.
15576 (Frecursion_depth): Wrap around reliably on integer overflow.
15577 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15578 since some callers pass EMACS_INT values.
15579 (Fsingle_key_description): Don't crash if symbol name contains more
15580 than MAX_ALLOCA bytes.
15581 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15582 (get_minibuffer): Arg is now EMACS_INT, not int.
15583 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15584 (esprintf, exprintf, evxprintf): New decls.
15585 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15587 * dbusbind.c (signature_cat): New function.
15588 (xd_signature, Fdbus_register_signal):
15589 Do not overrun buffer; instead, report string overflow.
15591 * dispnew.c (add_window_display_history): Don't overrun buffer.
15592 Truncate instead; this is OK since it's just a log.
15594 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15595 even if the time zone offset is outlandishly large.
15596 Don't mishandle offset == INT_MIN.
15598 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15599 when creating daemon; the previous buffer-overflow check was incorrect.
15601 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15602 which has the guts of the old verror function.
15604 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15605 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15607 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15608 (font_unparse_xlfd): Don't blindly alloca long strings.
15609 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15610 fits in int, when using sprintf. Use single snprintf to count
15611 length of string rather than counting it via multiple sprintfs;
15612 that's simpler and more reliable.
15613 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15614 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15615 sprintf, in case result does not fit in int.
15617 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15618 (fontset_from_font): Print it.
15620 * frame.c (tty_frame_count): Now printmax_t, not int.
15621 (make_terminal_frame, set_term_frame_name): Print it.
15622 (x_report_frame_params): In X, window IDs are unsigned long,
15623 not signed long, so print them as unsigned.
15624 (validate_x_resource_name): Check for implausibly long names,
15625 and don't assume name length fits in 'int'.
15626 (x_get_resource_string): Don't blindly alloca invocation name;
15627 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15630 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15631 (xg_check_special_colors, xg_set_geometry):
15632 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15634 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15635 Use esprintf, not sprintf, in case result does not fit in int.
15637 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15638 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15639 it as a large positive number.
15640 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15641 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15643 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15644 in case result does not fit in int.
15646 * print.c (float_to_string): Detect width overflow more reliably.
15647 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15648 buffer overrun. Don't assume list length fits in 'int'. Treat
15649 print length of 0 as 0, not as infinity; to be consistent with other
15650 uses of print length in this function. Don't overflow print length
15651 index. Don't assume hash table size fits in 'long', or that
15652 vectorlike size fits in 'unsigned long'.
15654 * process.c (make_process): Use printmax_t, not int, to format
15655 process-name gensyms.
15657 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15659 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15660 to avoid potential buffer overrun.
15662 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15663 if X resource line is longer than 512 bytes.
15665 * xfns.c (x_window): Make sprintf buffer a bit bigger
15666 to avoid potential buffer overrun.
15668 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15670 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15672 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15674 Integer overflow fixes for scrolling, etc.
15675 Without these, Emacs silently mishandles large integers sometimes.
15676 For example, "C-u 4294967297 M-x recenter" was treated as if
15677 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15679 * xdisp.c (try_window_id): Check Emacs fixnum range before
15680 converting to 'int'.
15682 * window.c (window_scroll_line_based, Frecenter):
15683 Check that an Emacs fixnum is in range before assigning it to 'int'.
15684 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15685 values converted from Emacs fixnums.
15686 (Frecenter): Don't wrap around a line count if it is out of 'int'
15687 range; instead, treat it as an extreme value.
15688 (Fset_window_configuration, compare_window_configurations):
15689 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15691 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15692 that can exceed INT_MAX. Check that EMACS_INT value is in range
15693 before assigning it to the (possibly-narrower) index.
15694 (match_limit): Don't assume that a fixnum can fit in 'int'.
15696 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15699 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15700 (Fvertical_motion): Don't wrap around LINES values that don't fit
15701 in 'int'. Instead, treat them as extreme values. This is good
15702 enough for windows, which can't have more than INT_MAX lines anyway.
15704 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15706 * Require libxml/parser.h to avoid compilation warning.
15708 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15710 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15711 since this reportedly can destroy thread storage.
15713 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15715 * syntax.c (find_defun_start): Update all cache variables if
15716 exiting early (Bug#9401).
15718 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15720 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15722 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15723 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15724 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15726 * term.c (tty_append_glyph): New function.
15727 (produce_stretch_glyph): Static function and its prototype deleted.
15729 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15732 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15734 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15735 when checking :margin (Bug#9390).
15736 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15737 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15738 so that the name doesn't mislead. All uses changed.
15740 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15742 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15745 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15747 * xdisp.c (move_it_to): Don't bail out early when reaching
15748 position beyond to_charpos, if we are scanning backwards.
15749 (move_it_vertically_backward): When DY == 0, make sure we get to
15750 the first character in the line after the newline.
15752 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15754 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15755 (ccl_driver): Do not generate an out-of-range pointer.
15756 (Fccl_execute_on_string): Remove unnecessary check for
15757 integer overflow, noted by Stefan Monnier in
15758 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15759 Remove a FIXME that didn't need fixing.
15760 Simplify the newly-introduced buffer reallocation code.
15762 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15764 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15766 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15768 Integer and memory overflow issues (Bug#9196).
15770 * doc.c (get_doc_string): Rework so that
15771 get_doc_string_buffer_size is the actual buffer size, rather than
15772 being 1 less than the actual buffer size; this makes xpalloc more
15775 * image.c (x_allocate_bitmap_record, cache_image):
15776 * xselect.c (Fx_register_dnd_atom):
15777 Simplify previous changes by using xpalloc.
15779 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15780 since either will do and ptrdiff_t is convenient with xpalloc.
15782 * charset.c (charset_table_size)
15783 (struct charset_sort_data.priority): Now ptrdiff_t.
15784 (charset_compare): Don't overflow if priorities differ greatly.
15785 (Fsort_charsets): Don't assume list length fits in int.
15786 Check for size-calculation overflow when allocating sort data.
15787 (syms_of_charset): Allocate an initial charset table that is
15788 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15790 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15792 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15793 The actual value is always <= INT_MAX, and leaving it unsigned made
15794 overflow checking harder.
15796 * dispextern.h (struct glyph_matrix.rows_allocated)
15797 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15798 with xpalloc. The values are still always <= INT_MAX.
15800 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15802 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15803 (SAFE_NALLOCA): New macro.
15805 * region-cache.c (struct boundary.pos, find_cache_boundary)
15806 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15807 (set_cache_region, invalidate_region_cache)
15808 (revalidate_region_cache, know_region_cache, region_cache_forward)
15809 (region_cache_backward, pp_cache):
15810 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15811 so that ptrdiff_t * can be passed to xpalloc.
15812 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15813 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15814 (pp_cache): Don't assume cache_len fits in int.
15815 * region-cache.h: Adjust extern decls to match.
15817 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15818 EMACS_INT, since either will do, for xpalloc.
15820 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15821 (xnmalloc, xnrealloc, xpalloc): New functions.
15823 * bidi.c (bidi_shelve_header_size): New constant.
15824 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15825 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15827 * bidi.c (bidi_cache_shrink):
15828 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15830 Don't update size of array until after memory allocation succeeds,
15831 because xmalloc/xrealloc may not return.
15832 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15833 now that we have proper integer overflow checking.
15834 (record_overlay_string, overlay_strings): Catch overflows when
15835 calculating size of overlay_str_buf.
15837 * callproc.c (Fcall_process): Check for size overflow when
15838 calculating size of args2.
15839 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15840 Normally we prefer signed values, but sticking with ptrdiff_t would
15841 require adding more-complicated checks.
15843 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15844 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15845 Redo buffer-overflow calculations to avoid integer overflow.
15846 Add a FIXME comment where memory seems to be over-allocated.
15848 * character.c (Fstring): Check for size-calculation overflow.
15850 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15851 unnecessary integer overflow. Check for size overflow.
15852 (encode_coding_object): Don't update size until xmalloc succeeds.
15854 * composite.c (get_composition_id): Check for overflow in glyph
15855 length calculations.
15857 Integer and memory overflow fixes for display code.
15858 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15859 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15860 (scrolling_window): Check for overflow in size calculations.
15861 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15862 Don't assume glyph table len fits in int.

15864 (row_table_size): Now ptrdiff_t, not int.
15865 (scrolling_window): Avoid overflow in size calculations.
15866 Don't update size until allocation succeeds.
15867 * fns.c (concat): Check for overflow in size calculations.
15868 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15869 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15870 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15872 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15873 (get_doc_string): Check for size calculation overflow.
15874 Don't update size until allocation succeeds.
15875 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15876 EMACS_INT, where ptrdiff_t will do.
15877 (Fsubstitute_command_keys): Check for string overflow.
15879 * editfns.c (set_time_zone_rule): Don't assume environment length
15881 (message_length): Now ptrdiff_t, not int.
15882 (Fmessage_box): Don't update size until allocation succeeds.
15883 Don't assume message length fits in int.
15884 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15886 * emacs.c (main): Do not reallocate argv, since there is a null at
15887 the end that can be overwritten, and this way there's no need to
15888 worry about size-calculation overflow.
15889 (sort_args): Check for size-calculation overflow.
15891 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15893 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15895 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15896 (x_set_scroll_bar_width, x_figure_window_size):
15897 Check for integer overflow.
15898 (x_set_alpha): Do not assume XINT fits in int.
15900 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15901 This is for the members text_lines, text_cols, total_lines, total_cols,
15902 where the system imposes an 'int' limit.
15904 * fringe.c (Fdefine_fringe_bitmap):
15905 Don't update size until alloc works.
15907 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15908 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15910 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15911 Check for size-calculation overflow.
15912 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15913 do, as we prefer signed integers.
15914 (id_to_widget.max_size, id_to_widget.used)
15915 (xg_store_widget_in_map, xg_remove_widget_from_map)
15916 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15917 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15918 Use and return ptrdiff_t, not int.
15919 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15920 * gtkutil.h: Change prototypes to match the above.
15922 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15923 are duplicate now that they've been promoted to lisp.h.
15924 (x_allocate_bitmap_record, x_alloc_image_color)
15925 (make_image_cache, cache_image, xpm_load):
15926 Don't update size until alloc is done.
15927 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

15930 (ct_colors_allocated_max): New constant.
15931 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15934 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15935 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15936 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15937 Use ptrdiff_t, not int, to count maps.
15938 (read_char_minibuf_menu_prompt): Check for overflow in size
15939 calculations. Don't update size until allocation succeeds.
15940 Redo calculations to avoid overflow.
15941 * keyboard.h: Change prototypes to match the above.
15943 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15945 (current_minor_maps): Check for size calculation overflow.
15946 * keymap.h: Change prototypes to match the above.
15948 * lread.c (read1, init_obarray): Don't update size until alloc done.
15950 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15969 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15970 for command line length. Do not attempt to address one before the
15971 beginning of an array, as that's not portable.
15973 * term.c (max_frame_lines): Remove; unused.
15974 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15976 (encode_terminal_code, calculate_costs): Check for size
15977 calculation overflow.

15995 Use ptrdiff_t, not int, for sizes.
15996 (store_mode_line_noprop_char): Don't update size until alloc done.

15999 Use ptrdiff_t, not int, for sizes.
16000 (Finternal_make_lisp_face, cache_face):
16001 Check for size calculation overflow.
16002 (cache_face): Treat size calculation overflows as if they were
16003 memory exhaustion (the usual treatment), rather than aborting.
16005 * xfns.c (x_encode_text, x_set_name_internal)
16006 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16007 sizes, since they can exceed INT_MAX in size. Check for size
16008 calculation overflow.
16010 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16011 (xg_select): Check for size calculation overflow.
16012 Don't update size until alloc done.
16014 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16015 as sprintf is limited to int lengths.
16017 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16018 (X_LONG_MIN): New macros.
16019 Use them to make the following changes clearer.
16020 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16021 This change doesn't affect the value now, but it may help remind
16022 future maintainers not to raise the value too much later.
16023 (SELECTION_QUANTUM): Remove, replacing with ...
16024 (selection_quantum): ... new function, which avoids overflow.
16026 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16027 assumption that selection length fits in 'int'.
16028 (x_reply_selection_request, x_handle_selection_request)
16029 (x_get_window_property, receive_incremental_selection)
16030 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16031 (lisp_data_to_selection_data, clean_local_selection_data):
16032 Use ptrdiff_t, not int, to record length of selection.
16033 (x_reply_selection_request, x_get_window_property)
16034 (receive_incremental_selection, x_property_data_to_lisp):
16035 Redo calculations to avoid overflow.
16036 (x_reply_selection_request): When sending hint, ceiling it at
16037 X_LONG_MAX rather than relying on wraparound overflow to send
16039 (x_get_window_property, receive_incremental_selection)
16040 (lisp_data_to_selection_data, x_property_data_to_lisp):
16041 Check for size-calculation overflow.
16042 (x_get_window_property, receive_incremental_selection)
16043 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16044 Don't store size until memory allocation succeeds.
16045 (x_get_window_property): Plug memory leak on memory exhaustion.
16046 Don't double-block input; malloc is safe here. Don't assume 2**34
16047 - 4 fits in unsigned long. Add an xassert to check
16048 XGetWindowProperty overflow. Be more careful about overflow
16049 calculations, and distinguish size from memory overflow better.
16050 (receive_incremental_selection): When tracing, don't assume
16051 unsigned int is less than INT_MAX.
16052 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16053 harmful) conversions of unsigned short to int.
16054 (lisp_data_to_selection_data): Don't assume that integers
16055 in the range -65535 through -1 fit in an X unsigned short.
16056 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16057 result parameters unless successful. Rely on cons_to_unsigned
16058 to report problems with elements; the old code wasn't right anyway.
16059 (x_check_property_data): Check for int overflow; we cannot use
16060 a wider type due to X limits.
16061 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16063 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16065 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16066 (x_term_init): Check for size calculation overflow.
16067 (x_color_cells): Don't store size until memory allocation succeeds.
16068 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16069 Don't assume alloca size is less than MAX_ALLOCA.
16070 (x_term_init): Don't assume length fits in int (sprintf is limited
16073 Use ptrdiff_t for composition IDs.
16074 * character.c (lisp_string_width):
16075 * composite.c (composition_table_size, n_compositions)
16076 (get_composition_id, composition_gstring_from_id):
16077 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):

16091 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
16092 * image.c (xpm_get_color_table_h):
16093 * lisp.h (hash_lookup, hash_put):
16094 * minibuf.c (Ftest_completion):
16095 Use ptrdiff_t for hash table indexes, not int (which is too
16096 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16097 32-bit --with-wide-int hosts).
16099 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16100 Add a FIXME comment about memory leaks.
16101 (syms_of_charset): Don't assume xmalloc returns.
16103 Don't assume that stated character widths fit in int.
16104 * character.c (Fchar_width, c_string_width, lisp_string_width):
16105 * character.h (CHAR_WIDTH):
16106 * indent.c (MULTIBYTE_BYTES_WIDTH):
16107 Use sanitize_char_width to avoid undefined and/or bad behavior
16108 with outlandish widths.
16109 * character.h (sanitize_tab_width): Rename from sanitize_width,
16110 now that we have two such functions. All uses changed.
16111 (sanitize_char_width): New inline function.
16113 Don't assume that tab-width fits in int.
16114 * character.h (sanitize_width): New inline function.
16115 (SANE_TAB_WIDTH): New macro.
16116 (ASCII_CHAR_WIDTH): Use it.
16117 * indent.c (sane_tab_width): Remove. All uses replaced by
16118 SANE_TAB_WIDTH (current_buffer).
16119 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
16121 * fileio.c: Integer overflow issues with file modes.
16122 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16124 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16125 Remove unreachable code.
16126 (read_hex, load_charset_map_from_file): Check for integer overflow.
16128 * xterm.c: Don't go over XClientMessageEvent limit.
16129 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16130 (x_send_scroll_bar_event): Likewise. Check that the size does not
16131 exceed limits imposed by XClientMessageEvent, as well as the usual
16132 ptrdiff_t and size_t limits.
16134 * keyboard.c: Overflow, signedness and related fixes.
16135 (make_lispy_movement): Use same integer type in forward decl
16136 that is used in the definition.
16137 (read_key_sequence, keyremap_step):
16138 Change bufsize argument back to int, undoing my 2011-03-30 change.
16139 We prefer signed types, and int is wide enough here.
16140 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16141 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16142 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16143 length, not size_t. Use ptrdiff_t for index, not int.
16144 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16145 possibility of integer overflow.
16147 Overflow, signedness and related fixes for images.
16149 * dispextern.h (struct it.stack[0].u.image.image_id)
16150 (struct_it.image_id, struct image.id, struct image_cache.size)
16151 (struct image_cache.used, struct image_cache.ref_count):

16157 * xdisp.c (calc_pixel_width_or_height):
16158 * xfns.c (image_cache_refcount):
16159 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16160 on typical 64-bit hosts.

16166 when the callers expect that.
16167 (image_ascent): Redo ascent calculation to avoid int overflow.
16168 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16169 (lookup_image): Remove unnecessary tests.
16170 (xbm_image_p): Locals are now of int, not EMACS_INT,
16171 since parse_image_check makes sure they fit into int.
16172 (png_load, gif_load, svg_load_image):
16173 Prefer int to unsigned where either will do.
16174 (tiff_handler): New function, combining the cores of the
16175 old tiff_error_handler and tiff_warning_handler.
16176 This function is rewritten to use vsnprintf and thereby avoid
16177 stack buffer overflows. It uses only the features of vsnprintf
16178 that are common to both POSIX and native Microsoft.
16179 (tiff_error_handler, tiff_warning_handler): Use it.
16180 (tiff_load, gif_load, imagemagick_load_image):
16181 Don't assume :index value fits in 'int'.
16182 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16183 (imagemagick_load_image): Check that crop parameters fit into
16184 the integer types that MagickCropImage accepts. Don't assume
16185 Vimagemagick_render_type has a nonnegative value. Don't assume
16186 size_t fits in 'long'.
16187 (gs_load): Use printmax_t to print the widest integers possible.
16188 Check for integer overflow when computing image height and width.
16190 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16192 * xdisp.c (redisplay_window): Don't force window start if point
16193 will be invisible in the resulting window. (Bug#9324)

16197 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16198 the display spec is of the form `(space ...)'.
16199 (handle_display_spec): Return the value returned by
16200 handle_single_display_spec, not just 1 or zero.
16201 (handle_single_display_spec): If the display spec is of the form
16202 `(space ...)', and specifies display in the text area, return 2
16204 (try_cursor_movement): Check for the need to scroll more
16205 accurately, and prefer exact match for point under bidi.
16206 Don't advance `row' beyond the last row of the window.
16208 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16209 into disp_prop; all users changed.
16211 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16212 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16213 for the text covered by the display property.
16215 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
16217 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

16223 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16224 buffers, return left-to-right.
16225 (set_cursor_from_row): Consider candidate row a win if its glyph
16226 represents a newline and point is on that newline. Fixes cursor
16227 positioning on the newline at EOL of R2L text within L2R
16228 paragraph, and vice versa.
16229 (try_cursor_movement): Check continued rows, in addition to
16230 continuation rows. Fixes unwarranted scroll when point enters a
16231 continued line of R2L text within an L2R paragraph, or vice versa.
16232 (cursor_row_p): Consider the case of point being equal to
16233 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16234 from the end of a short line to the beginning of a continued line
16235 of R2L text within L2R paragraph.
16236 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16237 composed characters.
16239 * bidi.c (bidi_check_type): Use xassert.

16248 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
16250 * nsfont.m (ns_otf_to_script): Fix typo.
16252 2011-08-22 Kenichi Handa <handa@m17n.org>
16254 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16255 extra slot even if the purpose is char-code-property-table.
16257 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16259 * xdisp.c (redisplay_window): When computing centering_position,
16260 account for the height of the header line. (Bug#8874)
16262 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16263 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16264 candidate is selected by the mouse, and that candidate has a
16265 composed character under the mouse.
16267 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16268 coordinates reported by pos-visible-in-window-p for a composed
16269 character in column zero.
16271 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16273 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16275 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16277 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16278 consider it a hit if to_charpos is anywhere in the range of the
16279 composed buffer positions.
16281 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16283 * image.c (gif_load): Don't assume that each subimage has the same
16284 dimensions as the base image. Handle disposal method that is
16285 "undefined" by the gif spec (Bug#9335).
16287 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16289 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
16290 (Fcondition_case): Document `debug' symbol in error handler.
16292 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16294 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16295 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16296 from an Org mode buffer to a Speedbar frame.
16298 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16299 a composition, take its buffer position from IT->cmp_it.charpos.
16300 Fixes cursor positioning at the beginning of a line that begins
16301 with a composed character.
16303 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16305 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16306 character bidirectional type, use STRONG_L instead. Fixes crashes
16307 in a buffer produced by `describe-categories'.
16309 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16310 members before the level stack, so they would be saved and
16311 restored when copying iterator state. Fixes incorrect reordering
16312 around TABs covered by display properties.
16314 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16316 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
16318 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
16320 * eval.c (internal_condition_case, internal_condition_case_1)
16321 (internal_condition_case_2, internal_condition_case_n):
16322 Remove unnecessary aborts (Bug#9081).
16324 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16326 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16327 has no `load' handler, try opening the file locally. (Bug#9311)
16329 2011-08-16 Ken Brown <kbrown@cornell.edu>
16331 * gmalloc.c: Expand comment.
16333 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16335 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16336 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16338 2011-08-16 Ken Brown <kbrown@cornell.edu>
16340 Fix memory allocation problems in Cygwin build (Bug#9273).
16342 * unexcw.c ( __malloc_initialized): Declare external variable.
16343 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16345 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16347 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
16349 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16350 in the static heap.
16351 [CYGWIN] (special_realloc): New function.
16352 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

16368 * chartab.c: Improve commentary for the uniprop_table API.
16370 * bidi.c (bidi_paragraph_init): Support zero value of
16371 bidi_ignore_explicit_marks_for_paragraph_level.
16372 (bidi_initialize): Use uniprop_table instead of including
16373 biditype.h and bidimirror.h.
16375 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16376 coordinates of the iterator when restoring from ppos_it.
16379 2011-08-14 Kenichi Handa <handa@m17n.org>
16381 * process.c (create_process): Call setup_process_coding_systems
16382 after the pid of the process is set to -1 (Bug#8162).
16384 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16386 * xdisp.c (move_it_in_display_line_to): Don't invoke
16387 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16388 ppos_it. Fixes vertical cursor motion when line beginning is
16389 covered by an image. (Bug#9296)
16391 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16393 * nsterm.h (ns_run_ascript): Declare.
16394 (NSAPP_DATA2_RUNASSCRIPT): Define.
16396 * nsfns.m (as_script, as_result, as_status): New static variables.
16397 (ns_run_ascript): New function.
16398 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16399 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16400 the event loop. Get status from as_status (Bug#7276).
16402 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16403 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16404 the event loop (Bug#7276).
16406 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16408 * gnutls.c (QCgnutls_bootprop_priority)
16409 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16410 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16411 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16412 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16413 (QCgnutls_bootprop_verify_hostname_error)
16414 (QCgnutls_bootprop_callbacks_verify): Rename from
16415 Qgnutls_bootprop_..., all uses changed.
16417 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16420 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16422 * xfaces.c (Qframe_set_background_mode): Now static.
16423 * dispextern.h (Qframe_set_background_mode): Remove decl.
16425 * process.c (Fnetwork_interface_info): Declare local only if needed.
16427 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16429 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16430 (Fnetwork_interface_list): Allocate in increments of bytes instead
16431 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16432 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16434 (struct ifflag_def): notrailers is smart on OSX.
16435 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16436 Get hardware address with getifaddrs if available.
16438 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16440 * xdisp.c (iterate_out_of_display_property): xassert that
16441 IT->position is set to within IT->object's boundaries. Break from
16442 the loop as soon as EOB is reached; avoids infloops in redisplay
16443 when IT->position is set up wrongly due to some bug.
16444 Set IT->current to match the bidi iterator unconditionally.
16445 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16446 entry. Force push_it to save on the stack the current
16447 buffer/string position, to be restored by pop_it. Fix flags in
16448 the iterator structure wrt the object coming from a display
16449 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16450 properties. (Bug#9284)
16452 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16454 * fontset.c (fontset_get_font_group): Add proper type checks.
16457 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

16467 no-display-properties-and-no-overlays under bidi display.
16468 Set disp_pos in the bidi iterator to avoid searches for display
16469 properties and overlays.
16471 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16473 * editfns.c (Fset_time_zone_rule): Document relationship with the

16477 the font entity extracted from the cache (Bug#8109).
16479 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16481 * composite.c (autocmp_chars): Don't reset point. That is done by
16482 restore_point_unwind (Bug#5984).
16484 2011-08-07 Juri Linkov <juri@jurta.org>
16486 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16487 to show the arg `TIME' instead of `TIMEVAL'.
16489 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16491 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16492 display property strides EOL and includes a newline, as in
16493 longlines-mode. (Bug#9254)
16494 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16495 word-wrap under bidirectional display. (Bug#9224)
16497 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16498 is non-zero, even if the data buffer is NULL. Fixes a crash in
16499 vertical-motion with longlines-mode. (Bug#9254)
16501 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16503 * bidi.c <bidi_cache_total_alloc>: Now static.
16504 (bidi_initialize): Initialize bidi_cache_total_alloc.
16506 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16509 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16510 amount allocated this far in `bidi_cache_total_alloc'.
16511 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16512 non-zero, only free the data buffer without restoring the cache
16513 contents. All callers changed.
16515 * dispextern.h (bidi_unshelve_cache): Update prototype.
16517 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16518 (move_it_in_display_line, move_it_to)
16519 (move_it_vertically_backward, move_it_by_lines): Replace the call
16520 to xfree to an equivalent call to bidi_unshelve_cache.
16521 (move_it_in_display_line_to): Fix logic of returning
16522 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16524 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16526 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16527 came from a string character with a `cursor' property. (Bug#9229)
16529 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16531 * Makefile.in (LIB_PTHREAD): New variable.
16532 (LIBES): Add LIB_PTHREAD (Bug#9216).
16534 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16535 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16537 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16539 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16541 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16543 * xterm.c (x_find_topmost_parent): New function.
16544 (x_set_frame_alpha): Find topmost parent window with
16545 x_find_topmost_parent and set the property there also (bug#9181).
16546 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16548 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16550 * callproc.c (Fcall_process): Avoid vfork clobbering
16551 the local vars buffer, coding_systems, current_dir.
16553 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16555 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16557 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16559 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16560 so that it is not optimized away.
16562 * xdisp.c (compute_display_string_pos): Remove unused local.
16564 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16566 Fix slow cursor motion and scrolling in large buffers with
16567 selective display, like Org Mode buffers. (Bug#9218)
16569 * dispextern.h (struct bidi_it): New member disp_prop_p.
16571 * xdisp.c: Remove one-slot cache of display string positions.
16572 (compute_display_string_pos): Accept an additional argument
16573 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16574 for a display string or property. If found, set DISP_PROP_P
16577 * bidi.c (bidi_fetch_char): Accept an additional argument
16578 DISP_PROP_P, and pass it to compute_display_string_pos.
16579 Only handle text covered by a display string if DISP_PROP_P is returned
16580 non-zero. All callers of bidi_fetch_char changed.
16582 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16584 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16586 2010-12-03 Don March <don@ohspite.net>
16588 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16589 last character M-[char] is translated to ESC [char] (bug#7541).
16591 2011-08-02 Kenichi Handa <handa@m17n.org>
16593 * lisp.h (uniprop_table): Extern it.
16595 * chartab.c (uniprop_table): Make it non-static.
16597 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16599 * xdisp.c (forward_to_next_line_start): Accept additional argument
16600 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16602 (reseat_at_next_visible_line_start): Use the bidi iterator state
16603 returned by forward_to_next_line_start to restore the state of
16604 it->bidi_it after backing up to previous newline. (Bug#9212)
16606 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16608 * regex.c (re_comp): Protoize.
16609 (re_exec): Fix return type.
16610 (regexec): Fix type of `ret'. (Bug#9203)
16612 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16614 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16615 This is needed if max-image-size is a floating-point number.
16617 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16619 * print.c (print_object): Print empty symbol as ##.
16621 * lread.c (read1): Read ## as empty symbol.
16623 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16625 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16626 setting frame foreground color (Bug#9175).
16627 (x_set_background_color): Likewise.
16629 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16630 contents (Bug#9176).
16631 (EmacsTooltip -init): Remove bezels and add shadows to
16634 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16635 or scroll bar (Bug#8470).
16637 * nsfont.m (nsfont_open): Remove assignment to voffset and
16638 unnecessary vars hshink, expand, hd, full_height, min_height.
16639 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16641 * nsterm.h (nsfont_info): Remove voffset field.
16643 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16645 Implement strike-through and overline on NextStep (Bug#8863).
16647 * nsfont.m (nsfont_open): Use underline position provided by font,
16648 instead of hard-coded value of 2.
16649 (nsfont_draw): Call ns_draw_text_decoration instead.
16651 * nsterm.h: Add declaration for ns_draw_text_decoration.
16653 * nsterm.m (ns_draw_text_decoration): New function for drawing
16654 underline, overline, and strike-through.
16655 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16656 ns_draw_text_decoration. Change treatment of cursor drawing to
16657 accommodate underlining, etc.
16659 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16661 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16664 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16666 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16667 Without this fix, if a signal arrives just after memory fills up,
16668 'malloc' might be invoked reentrantly.
16670 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16671 In other words, assume that every image size is allowed, on non-X
16672 hosts. This assumption is probably wrong, but it lets Emacs compile.
16674 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16676 * regex.c (re_iswctype): Convert return values to boolean.
16678 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16680 * xdisp.c (compute_display_string_pos): Don't use cached display
16681 string position if the buffer had its restriction changed.
16684 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16686 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16688 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16690 Integer signedness and overflow and related fixes. (Bug#9079)
16692 * bidi.c: Integer size and overflow fixes.
16693 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16694 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16695 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16696 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16697 (bidi_find_other_level_edge):
16698 Use ptrdiff_t instead of EMACS_INT where either will do.
16699 This works better on 32-bit hosts configured --with-wide-int.
16700 (bidi_cache_ensure_space): Check for size-calculation overflow.
16701 Use % rather than repeated addition, for better worst-case speed.
16702 Don't set bidi_cache_size until after xrealloc returns, because it
16704 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16705 (bidi_cache_ensure_space): Also check that the bidi cache size
16706 does not exceed that of the largest Lisp string or buffer. See Eli
16707 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16709 * alloc.c (__malloc_size_t): Remove.
16710 All uses replaced by size_t. See Andreas Schwab's note
16711 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16713 * image.c: Improve checking for integer overflow.
16714 (check_image_size): Assume that f is nonnull, since
16715 it is always nonnull in practice. This is one less thing to
16716 worry about when checking for integer overflow later.
16717 (x_check_image_size): New function, which checks for integer
16718 overflow issues inside X.
16719 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16720 This removes the need for a memory_full check.
16721 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16722 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16723 (xbm_read_bitmap_data): Change locals back to 'int', since
16724 their values must fit in 'int'.
16725 (xpm_load_image, png_load, tiff_load):
16726 Invoke x_create_x_image_and_pixmap earlier,
16727 to avoid much needless work if the image is too large.
16728 (tiff_load): Treat overly large images as if
16729 x_create_x_image_and_pixmap failed, not as malloc failures.
16730 (gs_load): Use x_check_image_size.
16732 * gtkutil.c: Omit integer casts.
16733 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16734 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16736 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16738 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16739 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16740 would wrongly return t on a 64-bit host.
16742 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16743 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16744 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16745 and therefore cause GCC to emit a bogus diagnostic in some cases.
16747 * image.c: Integer signedness and overflow and related fixes.
16748 This is not an exhaustive set of fixes, but it's time to
16749 record what I've got.
16750 (lookup_pixel_color, check_image_size): Remove redundant decls.
16751 (check_image_size): Don't assume that arbitrary EMACS_INT values
16752 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16753 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16754 (tiff_load, imagemagick_load_image):
16755 Check for overflow in size calculations.
16756 (x_create_x_image_and_pixmap): Remove unnecessary test for
16757 xmalloc returning NULL; that can't happen.
16758 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16759 (xpm_color_bucket): Use better integer hashing function.
16760 (xpm_cache_color): Don't possibly over-allocate memory.
16761 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16762 (gif_memory_source):
16763 Use ptrdiff_t, not int or size_t, to record sizes.
16764 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16765 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16766 either works, as we prefer signed integers.
16767 (tiff_read_from_memory, tiff_write_from_memory):
16768 Return tsize_t, not size_t, since that's what the TIFF API wants.
16769 (tiff_read_from_memory): Don't fail simply because the read would
16770 go past EOF; instead, return a short read.
16771 (tiff_load): Omit no-longer-needed casts.
16772 (Fimagemagick_types): Don't assume size fits into 'int'.
16774 Improve hashing quality when configured --with-wide-int.
16775 * fns.c (hash_string): New function, taken from sxhash_string.
16776 Do not discard information about ASCII character case; this
16777 discarding is no longer needed.
16778 (sxhash-string): Use it. Change sig to match it. Caller changed.
16779 * lisp.h: Declare it.
16780 * lread.c (hash_string): Remove, since we now use fns.c's version.
16781 The fns.c version returns a wider integer if --with-wide-int is
16782 specified, so this should help the quality of the hashing a bit.
16784 * emacs.c: Integer overflow minor fix.
16785 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16786 Define only if GNU_LINUX.
16787 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16789 * dispnew.c: Integer signedness and overflow fixes.
16790 Remove unnecessary forward decls, that were a maintenance hassle.
16791 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16793 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16794 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16795 (prepare_desired_row, line_draw_cost):
16796 Use int, not unsigned, where either works.
16797 (save_current_matrix, restore_current_matrix):
16798 Use ptrdiff_t, not size_t, where either works.
16799 (init_display): Check for overflow more accurately, and without
16800 relying on undefined behavior.
16802 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16803 Remove, replacing with the new symbols in lisp.h. All uses changed.
16804 * fileio.c (make_temp_name):
16805 * filelock.c (lock_file_1, lock_file):
16806 * xdisp.c (message_dolog):
16807 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16808 Use pMd etc. instead.
16809 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16810 replacing the pWIDE etc. symbols removed from editfns.c.
16812 * keyboard.h (num_input_events): Now uintmax_t.
16813 This is (very slightly) less likely to mess up due to wraparound.
16816 * buffer.c: Integer signedness fixes.
16817 (alloc_buffer_text, enlarge_buffer_text):
16818 Use ptrdiff_t rather than size_t when either will do, as we prefer
16821 * alloc.c: Integer signedness and overflow fixes.
16822 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16823 (__malloc_size_t): Default to size_t, not to int.
16824 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16825 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16826 Prefer ptrdiff_t to size_t when either would do, as we prefer
16828 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16829 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16830 Now const. Initialize with values that are in range even if char
16832 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16833 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16834 These functions do the right thing with sizes > 2**32.
16835 (check_depth): Now ptrdiff_t, not int.
16836 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16837 Adjust to new way of storing sizes. Check for size overflow bugs
16839 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16840 slightly wrong anyway, as it missed one instance of
16841 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16842 (refill_memory_reserve): Omit needless cast to size_t.
16843 (mark_object_loop_halt): Mark as externally visible.
16845 * xselect.c: Integer signedness and overflow fixes.
16846 (Fx_register_dnd_atom, x_handle_dnd_message):
16847 Use ptrdiff_t, not size_t, since we prefer signed.
16848 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16849 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16850 x_dnd_atoms_size and x_dnd_atoms_length.
16852 * doprnt.c: Prefer signed to unsigned when either works.
16854 * doprnt.c (doprnt):
16856 * xdisp.c (vmessage):
16857 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16858 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16859 prefer signed arithmetic to avoid comparison confusion.
16860 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16861 but is a bit tricky.
16863 Assume freestanding C89 headers, string.h, stdlib.h.
16864 * data.c, doprnt.c, floatfns.c, print.c:
16865 Include float.h unconditionally.
16866 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16867 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16868 * regex.c: Likewise for stddef.h, string.h.
16869 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16870 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16871 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16872 (STDC_HEADERS): Remove obsolete defines.
16873 * sysdep.c: Include limits.h unconditionally.
16875 Assume support for memcmp, memcpy, memmove, memset.
16876 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16877 * regex.c (memcmp, memcpy):
16878 Remove; we assume C89 now.
16880 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16881 (__malloc_safe_bcopy): Remove; no longer needed.
16883 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16884 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16885 well either way, and we prefer signed to unsigned.
16887 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16889 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16890 closes the connection while we're reading (bug#9182).
16892 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16894 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16895 are specified (Bug#9168).
16897 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16899 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16900 Found by GCC static checking and --with-wide-int on a 32-bit host.
16902 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16904 * xdisp.c (compute_display_string_pos): Fix logic of caching
16905 previous display string position. Initialize cached_prev_pos to
16906 -1. Fixes slow-down at the beginning of a buffer.
16908 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16910 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16911 for attrs[LFACE_FONTSET_INDEX].
16913 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16915 * xml.c (parse_region): Remove unused local
16916 that was recently introduced.
16918 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16920 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16921 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16923 * xdisp.c (move_it_in_display_line_to): Record the best matching
16924 position for TO_CHARPOS while scanning the line, and restore it on
16925 exit if none of the characters scanned was an exact match.
16926 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16927 when exact match is impossible due to invisible text, and the
16928 lines are truncated.
16930 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16932 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16935 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16937 Fix a significant slow-down of cursor motion with C-n, C-p,
16938 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16939 auto-repeat under bidi redisplay in fontified buffers.
16940 * xdisp.c (compute_stop_pos_backwards): New function.
16941 (next_element_from_buffer): Call compute_stop_pos_backwards to
16942 find a suitable prev_stop when we find ourselves before
16944 (reseat): Don't look for prev_stop, as that could mean a very long
16946 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16947 <cached_disp_overlay_modiff>: Cache for last found display string
16949 (compute_display_string_pos): Return the cached position if asked
16950 about the same buffer in the same area of character positions, and
16951 the buffer wasn't changed since the time the display string
16952 position was cached.
16954 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16956 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16957 is an integer, which is important for empty lines. (Bug#9149)
16959 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16961 * frame.c (Fmodify_frame_parameters): In tty case, update the
16962 default face if necessary (Bug#4238).
16964 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16966 * editfns.c (Fstring_to_char): No need to explain what a character
16967 is in the docstring (Bug#6576).
16969 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16971 * xml.c (parse_region): Make sure we always return a tree.
16973 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16975 * xml.c (parse_region): If a document contains only comments,
16978 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16980 * xml.c (make_dom): Return comments, too.
16982 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16985 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16986 and the surrounding thread.
16987 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16988 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16989 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16991 * s/openbsd.h (BROKEN_SIGIO): Define.
16992 * unexelf.c (unexec) [__OpenBSD__]:
16993 Don't update the .mdebug section of the Alpha COFF symbol table.
16995 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16997 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17000 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17002 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17003 This fixes some race conditions on the permissions of any newly
17006 * alloc.c (valid_pointer_p): Use pipe, not open.
17007 This fixes some permissions issues when debugging.
17009 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17010 If fchown fails to set both uid and gid, try to set just gid,
17011 as that is sometimes allowed. Adjust the file's mode to eliminate
17012 setuid or setgid bits that are inappropriate if fchown fails.
17014 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17016 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

17028 symbol character follows.
17030 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17032 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17033 This works around a problem with the previous change to Fcopy_file.
17034 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17035 and without this change, GCC might complain about discarding
17036 fchown's return value.
17038 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17040 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17042 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17044 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17046 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17048 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17049 it's used from the C level.
17051 * process.c: Use the same condition for POLL_FOR_INPUT in both
17052 keyboard.c and process.c (bug#1858).
17054 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17056 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17057 (Fgnutls_boot): Use it.
17059 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17061 * doc.c (Fsubstitute_command_keys): Revert last change.
17063 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17065 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17066 quotes the next character, and doesn't affect other longer
17067 sequences (bug#8935).
17069 * lread.c (syms_of_lread): Clarify that is isn't only
17070 `eval-buffer' and `eval-defun' that's affected by
17071 `lexical-binding' (bug#8460).
17073 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17075 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17076 bidi redisplay when a line includes both an image and is truncated.
17078 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17080 Fix minor problems found by static checking.
17081 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17082 (elsz): Now a signed constant, not a size_t var. We prefer signed
17083 types to unsigned, to avoid integer comparison confusion. Without
17084 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17085 "cannot optimize loop, the loop counter may overflow", a symptom
17087 * indent.c (Fvertical_motion): Mark locals as initialized.
17088 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17090 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

17113 buffer position was specified. Initialize paragraph_embedding to
17115 (reseat_to_string): Initialize the bidi iterator.
17116 (display_string): If we need to ignore text properties of
17117 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17118 original value of -1 will not work with bidi.)
17119 (compute_display_string_pos): First arg is now struct
17120 `text_pos *'; all callers changed. Support display properties on
17122 (compute_display_string_end): Support display properties on Lisp
17124 (init_iterator, reseat_1, reseat_to_string): Initialize the
17125 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17126 when iterating on a string not from display properties).

17128 Fix calculation of the object to scan. Fixes an error when using
17130 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17131 base_level_stop; instead, set base_level_stop to BEGV.
17132 Fixes crashes in vertical-motion.
17133 (next_element_from_buffer): Improve commentary for when
17134 the iterator is before prev_stop.
17135 (init_iterator): Initialize bidi_p from the default value of
17136 bidi-display-reordering, not from buffer-local value. Use the
17137 buffer-local value only if initializing for buffer iteration.

17158 parts of next_element_from_buffer, next_element_from_string, and
17159 next_element_from_c_string.

17161 (display_menu_bar): Force left-to-right direction. Add a FIXME
17162 comment for making that be controlled by a user option.

17172 iterator for displaying display or overlay strings.
17173 (forward_to_next_line_start): Don't use the shortcut if
17175 (back_to_previous_visible_line_start): If handle_display_prop
17176 pushed the iterator stack, restore the internal state of the bidi
17177 iterator by calling bidi_pop_it same number of times.
17178 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17179 and we are bidi-iterating, don't decrement the iterator position;
17180 instead, set the first_elt flag in the bidi iterator, to produce
17182 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17183 (push_display_prop): xassert that we are iterating a buffer.
17184 (push_it, pop_it): Save and restore paragraph_embedding member.
17185 (handle_single_display_spec, next_overlay_string)
17186 (get_overlay_strings_1, reseat_1, reseat_to_string)
17187 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17188 correctly. Don't assume unibyte strings are not bidi-reordered.

17197 property. Fix a typo in popping stretch info. Add an assertion
17198 for verifying that the iterator position is in sync with the bidi
17200 (handle_single_display_spec, get_overlay_strings_1)

17225 displayed in margins. (Bug#8133) (Bug#8867)
17226 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

17254 changed to -1 and -2, respectively.
17255 (bidi_char_at_pos): New function.
17256 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

17342 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17344 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17345 The old code sometimes used this field without initializing it.
17347 * alloc.c (gc_sweep): Don't read past end of array.
17348 In theory, the old code could also have corrupted Emacs internals,
17349 though it'd be very unlikely.

17453 sigprocmask is portable only for single-threaded applications, and

17615 if Emacs is configured with --with-wide-int.
17616 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17653 Random fixes. E.g., (random) never returned negative values.
17654 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17655 subseconds part to the entropy, as that's a bit more random.
17656 Prefer signed to unsigned, since the signedness doesn't matter and
17657 in general we prefer signed. When given a limit, use a
17658 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17659 latter isn't right if USE_2_TAGS_FOR_INTS.
17660 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17661 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17673 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17674 This is more efficient than Ffile_directory_p and avoids a minor race.

17678 * buffer.c (Foverlay_put): Say what the return value is
17681 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17685 error be more correct.
17687 * fns.c (Frequire): Remove the mention of the .gz files, since

17704 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17705 Also (re)move comments that are misplaced or no longer relevant.

17734 * lread.c (syms_of_lread): Mention single symbols defined by

17790 (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
17791 with value as argument.
17792 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
17793 g_settings_new (Bug#8967). Do not create gsettings_obj.

17806 * eval.c (struct backtrace): Simplify and port the data structure.
17807 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17808 signed bit field, as this assumption is not portable and it makes
17809 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17810 "char debug_on_exit : 1" as this is not portable either; instead,
17811 use the portable "unsigned int debug_on_exit : 1". Remove unused
17812 member evalargs. Remove obsolete comments about cc bombing out.
17814 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17882 (emacs_fixed_new): Set priv->f to argument.
17883 (emacs_fixed_get_preferred_width)
17884 (emacs_fixed_get_preferred_height): Use min_width/height from
17885 frames size_hint to set minimum and natural (Bug#8919).
17886 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17887 and use min_width/height from frames size_hint to set
17888 min_width/height (Bug#8919).

17908 Use gnulib's dup2 module instead of rolling our own.
17909 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17976 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17978 Integer and buffer overflow fixes (Bug#8873).
17980 * print.c (printchar, strout): Check for string overflow.
17981 (PRINTPREPARE, printchar, strout):
17982 Don't set size unless allocation succeeds.
17984 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17985 for sizes. Check for string overflow more accurately.
17986 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17988 * macros.c: Integer and buffer overflow fixes.
17989 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17990 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17994 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17996 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17998 * lread.c: Integer overflow fixes.
17999 (read_integer): Radix is now EMACS_INT, not int,
18000 to improve quality of diagnostics for out-of-range radices.
18001 Calculate buffer size correctly for out-of-range radices.
18002 (read1): Check for integer overflow in radices, and in
18003 read-circle numbers.
18004 (read_escape): Avoid int overflow.
18005 (Fload, openp, read_buffer_size, read1)
18006 (substitute_object_recurse, read_vector, read_list, map_obarray):
18007 Use ptrdiff_t, not int, for sizes.

18022 2011-06-22 Leo Liu <sdl.web@gmail.com>
18024 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18025 Move to minibuffer.el.
18027 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18029 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18030 The following patches are for when GLYPH_DEBUG && !XASSERT.
18031 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18032 * dispnew.c (flush_stdout):
18033 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18034 Mark as externally visible.
18035 * dispnew.c (check_window_matrix_pointers): Now static.
18036 * dispnew.c (window_to_frame_vpos):
18037 * xfns.c (unwind_create_frame):
18038 * xterm.c (x_check_font): Remove unused local.
18039 * scroll.c (CHECK_BOUNDS):
18040 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18041 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18042 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18043 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18044 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18046 (debug_method_add): Use va_list and vsprintf rather than relying
18047 on undefined behavior with wrong number of arguments.
18048 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18049 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18050 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18051 since we're not interested in debugging glyphs with old libraries.
18052 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18053 GCC 4.6.0's static checking.
18055 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18057 Integer overflow and signedness fixes (Bug#8873).

18067 (x_create_bitmap_from_xpm_data):
18068 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18069 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18071 * xfaces.c (load_pixmap):
18072 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18073 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18074 (.bitmaps_last, struct x_output.icon_bitmap):
18075 Use ptrdiff_t, not int, for bitmap indexes.
18076 (x_allocate_bitmap_record): Check for size overflow.
18077 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18079 Use ptrdiff_t, not int, for overlay counts.
18080 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18081 * editfns.c (overlays_around, get_pos_property):
18082 * textprop.c (get_char_property_and_overlay):
18083 * xdisp.c (next_overlay_change, note_mouse_highlight):
18084 * xfaces.c (face_at_buffer_position):
18085 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18086 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18087 (Fnext_overlay_change, Fprevious_overlay_change)
18088 (mouse_face_overlay_overlaps, Foverlays_in):
18089 Use ptrdiff_t, not int, for sizes.
18090 (overlays_at, overlays_in): Check for size-calculation overflow.
18092 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18094 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18095 (x_session_initialize): Do not assume string length fits in int.
18097 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18098 This is unlikely, but can occur if DPI is outlandish.
18100 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18101 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18103 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18104 * xrdb.c (magic_file_p, search_magic_path):
18105 Omit last arg SUFFIX; it was always 0. All callers changed.
18106 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18108 * xfont.c (xfont_match): Avoid need for strlen.
18110 * xfns.c: Don't assume strlen fits in int.

18113 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18114 not unsigned long, as we prefer signed integers. All callers changed.
18115 Detect integer overflow in repeat count.
18116 (message_dolog): Don't assume print length fits in 39 bytes.
18117 (display_mode_element): Don't assume strlen fits in int.
18119 * termcap.c: Don't assume sizes fit in int and never overflow.
18120 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18121 (gobble_line): Check for size-calculation overflow.
18123 * minibuf.c (Fread_buffer):
18124 * lread.c (intern, intern_c_string):
18125 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18126 Don't assume string length fits in int.

18138 * filelock.c: Fix some buffer overrun and integer overflow issues.
18139 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18140 Reformulate so as not to need the command string.
18141 Invoke gzip -cd rather than gunzip, as it's more portable.
18142 (lock_info_type, lock_file_1, lock_file):
18143 Don't assume pid_t and time_t fit in unsigned long.
18144 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18145 (current_lock_owner): Prefer signed type for sizes.
18146 Use memcpy, not strncpy, where memcpy is what is really wanted.
18147 Don't assume (via atoi) that time_t and pid_t fit in int.
18148 Check for time_t and/or pid_t out of range, e.g., via a network share.
18149 Don't alloca where an auto var works fine.
18151 * fileio.c: Fix some integer overflow issues.
18152 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18153 Don't assume string length fits in int.
18154 (directory_file_name): Don't assume string length fits in long.
18155 (make_temp_name): Don't assume pid fits in int, or that its print
18156 length is less than 20.
18158 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18160 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18162 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18164 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

18167 * emacs.c: Don't assume string length fits in 'int'.
18168 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18169 (main): Don't invoke strlen when not needed.

18175 (Fgetenv_internal):
18176 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18178 * lread.c (invalid_syntax): Omit length argument.
18179 All uses changed. This doesn't fix a bug, but it simplifies the
18180 code away from its former Hollerith-constant appearance, and it's
18181 one less 'int' to worry about when looking at integer-overflow issues.
18182 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18184 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18185 This didn't break anything, but it didn't help either.
18186 It's confusing to put a bogus integer in a place where the actual
18187 value does not matter.
18188 (LIST_END_P): Remove unused macro and its bogus comment.
18189 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18191 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18192 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18194 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18195 We prefer signed types, and the value cannot exceed the EMACS_INT
18196 range anyway (because otherwise the length would not be representable).
18197 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18198 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18199 This avoids a GCC warning when WIDE_EMACS_INT.
18201 * indent.c (sane_tab_width): New function.
18202 (current_column, scan_for_column, Findent_to, position_indentation)
18203 (compute_motion): Use it. This is just for clarity.
18204 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18206 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18208 * lisp.h (lint_assume): New macro.
18209 * composite.c (composition_gstring_put_cache):
18210 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18212 * editfns.c, insdel.c:
18213 Omit unnecessary forward decls, to simplify future changes.
18215 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18217 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18219 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18220 Use much-faster test for byte-length change.
18221 Don't assume string byte-length fits in 'int'.
18222 Check that character arg fits in 'int'.
18223 (mapcar1): Declare byte as byte, for clarity.
18225 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18227 * fns.c (concat): Catch string overflow earlier.
18228 Do not rely on integer wraparound.
18230 * dispextern.h (struct it.overlay_strings_charpos)
18231 (struct it.selective): Now EMACS_INT, not int.
18232 * xdisp.c (forward_to_next_line_start)
18233 (back_to_previous_visible_line_start)
18234 (reseat_at_next_visible_line_start, next_element_from_buffer):
18235 Don't arbitrarily truncate the value of 'selective' to int.
18237 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18239 * composite.c: Don't truncate sizes to 'int'.
18240 (composition_gstring_p, composition_reseat_it)
18241 (composition_adjust_point): Use EMACS_INT, not int.
18242 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18243 not EMACS_UINT, for indexes.
18245 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18247 * buffer.c: Include <verify.h>.
18248 (struct sortvec.priority, struct sortstr.priority):
18249 Now EMACS_INT, not int.
18250 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18251 (struct sortstr.size, record_overlay_string)
18252 (struct sortstrlist.size, struct sortlist.used):
18253 Don't truncate size to int.
18254 (record_overlay_string): Check for size-calculation overflow.
18255 (init_buffer_once): Check at compile-time, not run-time.
18257 2011-06-22 Jim Meyering <meyering@redhat.com>
18259 Don't leak an XBM-image-sized buffer
18260 * image.c (xbm_load): Free the image buffer after using it.
18262 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18265 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18266 that Sun C diagnosed.
18267 * fns.c (secure_hash): Fix pointer signedness issue.
18268 * intervals.c (static_offset_intervals): New function.
18269 (offset_intervals): Use it.
18271 2011-06-21 Leo Liu <sdl.web@gmail.com>
18274 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18277 * fns.c (secure_hash): Rename from crypto_hash_function and change
18278 the first arg to accept symbols.
18279 (Fsecure_hash): New primitive.
18280 (syms_of_fns): New symbols.
18282 2011-06-20 Deniz Dogan <deniz@dogan.se>
18284 * process.c (Fset_process_buffer): Clarify return value in
18287 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18289 * dispnew.c (add_window_display_history): Use BVAR.
18291 * xdisp.c (debug_method_add): Use BVAR.
18292 (check_window_end, dump_glyph_matrix, dump_glyph)
18293 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18295 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18298 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18299 check till after the cache is created in init_frame_faces.
18301 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18303 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18305 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18307 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18308 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18309 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18311 Improve buffer-overflow checking (Bug#8873).
18312 * fileio.c (Finsert_file_contents):
18313 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18314 Remove the old (too-loose) buffer overflow checks.
18315 They weren't needed, since make_gap checks for buffer overflow.
18316 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18317 The old code merely checked for Emacs fixnum overflow, and relied
18318 on undefined (wraparound) behavior. The new code avoids undefined
18319 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18321 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18322 Tune. Don't use wider integers than needed. Don't use alloca.
18323 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18325 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18327 * insdel.c, lisp.h (buffer_overflow): New function.
18328 (insert_from_buffer_1, replace_range, replace_range_2):
18329 * insdel.c (make_gap_larger):
18330 * editfns.c (Finsert_char):
18331 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18333 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18335 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18337 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18339 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18340 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18342 * fileio.c: Don't assume EMACS_INT fits in off_t.
18343 (emacs_lseek): New static function.
18344 (Finsert_file_contents, Fwrite_region): Use it.
18345 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18347 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18349 * fns.c: Don't overflow int when computing a list length.
18350 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18351 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18352 truncation on 64-bit hosts. Check for QUIT every
18353 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18354 faster and is responsive enough.
18355 (Flength): Report an error instead of overflowing an integer.
18356 (Fsafe_length): Return a float if the value is not representable
18357 as a fixnum. This shouldn't happen except in contrived situations.
18358 (Fnthcdr, Fsort): Don't assume list length fits in int.
18359 (Fcopy_sequence): Don't assume vector length fits in int.
18361 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18362 (header_size, word_size): New constants.
18363 (allocate_vectorlike): Don't check size overflow here.
18364 (allocate_vector): Check it here instead, since this is the only
18365 caller of allocate_vectorlike that could cause overflow.
18366 Check that the new vector's length is representable as a fixnum.
18368 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18369 The previous code was bogus. For example, next_almost_prime (32)
18370 returned 39, which is undesirable as it is a multiple of 3; and
18371 next_almost_prime (24) returned 25, which is a multiple of 5 so
18372 why was the code bothering to check for multiples of 7?
18374 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18376 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18378 Variadic C functions now count arguments with ptrdiff_t.
18379 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18380 Back then I didn't know that the Emacs coding style prefers signed int.
18381 Also, in the meantime I found a few more instances where arguments
18382 were being counted with int, which may truncate counts on 64-bit
18383 machines, or EMACS_INT, which may be unnecessarily wide.
18384 * lisp.h (struct Lisp_Subr.function.aMANY)
18385 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18386 Arg counts are now ptrdiff_t, not size_t.
18387 All variadic functions and their callers changed accordingly.
18388 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18389 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18390 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18391 * callint.c (Fcall_interactively): Check arg count for overflow,
18392 to avoid potential buffer overrun. Use signed char, not 'int',
18393 for 'varies' array, so that we needn't bother to check its size
18394 calculation for overflow.
18395 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18396 * eval.c (apply_lambda):
18397 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18398 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18399 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18401 * callint.c (Fcall_interactively): Don't use index var as event count.
18403 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18404 * mem-limits.h (SIZE): Remove; no longer used.
18406 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18408 Remove unnecessary casts.
18409 * xterm.c (x_term_init):
18410 * xfns.c (x_set_border_pixel):
18411 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18412 These aren't needed now that we assume ANSI C.
18414 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18415 It's more likely to cause problems (due to unsigned overflow)
18418 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18420 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18422 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18424 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18426 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18428 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18430 GLYPH_CODE_FACE returns EMACS_INT, not int.
18431 * dispextern.h (merge_faces):
18432 * xfaces.c (merge_faces):
18433 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18434 Don't assume EMACS_INT fits in int.
18436 * character.h (CHAR_VALID_P): Remove unused parameter.
18437 * fontset.c, lisp.h, xdisp.c: All uses changed.
18439 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18441 * fns.c (concat): Minor tuning based on overflow analysis.
18442 This doesn't fix any bugs. Use int to hold character, instead
18443 of constantly refetching from Emacs object. Use XFASTINT, not
18444 XINT, for value known to be a character. Don't bother comparing
18445 a single byte to 0400, as it's always less.
18447 * floatfns.c (Fexpt):
18448 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18450 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18453 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18455 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18456 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18457 incorrectly succeed when S was a string, because 4294967386 was
18458 truncated before it was used.
18460 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18461 Otherwise, an out-of-range integer could cause undefined behavior
18464 * composite.c: Use int, not EMACS_INT, for characters.
18465 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18466 EMACS_INT, for values that are known to be in character range.
18467 This doesn't fix any bugs but is the usual style inside Emacs and
18468 may generate better code on 32-bit machines.
18470 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18471 This is for reasons similar to the recent CHAR_STRING fix.
18472 * charset.c (Fencode_char): Check that character arg is actually
18473 a character. Pass an int to ENCODE_CHAR.
18474 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18475 wider than 'int', as a compile-time check to prevent future regressions
18478 * character.c (char_string): Remove unnecessary casts.
18480 Make sure a 64-bit char is never passed to CHAR_STRING.
18481 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18482 by silently ignoring the top 32 bits, allowing some values
18483 that were far too large to be valid characters.
18484 * character.h: Include <verify.h>.
18485 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18486 arguments are no wider than unsigned, as a compile-time check
18487 to prevent future regressions in this area.
18489 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18490 (Fsubst_char_in_region):
18492 * xdisp.c (decode_mode_spec_coding):
18493 Adjust to CHAR_STRING's new requirement.
18494 * editfns.c (Finsert_char, Fsubst_char_in_region):
18495 * fns.c (concat): Check that character args are actually
18496 characters. Without this test, these functions did the wrong
18497 thing with wildly out-of-range values on 64-bit hosts.
18499 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18500 These casts should not be needed on 32-bit hosts, either.
18501 * keyboard.c (read_char):
18502 * lread.c (Fload): Remove casts to unsigned.
18504 * lisp.h (UNSIGNED_CMP): New macro.
18505 This fixes comparison bugs on 64-bit hosts.
18506 (ASCII_CHAR_P): Use it.
18507 * casefiddle.c (casify_object):
18508 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18509 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18510 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18511 * dispextern.h (FACE_FROM_ID):
18512 * keyboard.c (read_char): Use UNSIGNED_CMP.
18514 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18515 not to EMACS_INT, to avoid GCC warning.
18517 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18519 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18520 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18521 isn't needed on 32-bit machines.
18523 * buffer.c (Fgenerate_new_buffer_name):
18524 Use EMACS_INT for count, not int.
18525 (advance_to_char_boundary): Return EMACS_INT, not int.
18527 * data.c (Qcompiled_function): Now static.
18529 * window.c (window_body_lines): Now static.
18531 * image.c (gif_load): Rename local to avoid shadowing.
18533 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18534 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18535 * alloc.c (make_save_value): Integer argument is now of type
18536 ptrdiff_t, not int.
18537 (mark_object): Use ptrdiff_t, not int.
18538 * lisp.h (pD): New macro.
18539 * print.c (print_object): Use it.
18541 * alloc.c: Use EMACS_INT, not int, to count objects.
18542 (total_conses, total_markers, total_symbols, total_vector_size)
18543 (total_free_conses, total_free_markers, total_free_symbols)
18544 (total_free_floats, total_floats, total_free_intervals)
18545 (total_intervals, total_strings, total_free_strings):
18546 Now EMACS_INT, not int. All uses changed.
18547 (Fgarbage_collect): Compute overall total using a double, so that
18548 integer overflow is less likely to be a problem. Check for overflow
18549 when converting back to an integer.
18550 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18551 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18552 These were 'int' variables that could overflow on 64-bit hosts;
18553 they were never used, so remove them instead of repairing them.
18554 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18555 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18556 Previously, this ceilinged at INT_MAX, but that doesn't work on
18558 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18560 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18561 (allocate_vectorlike): Check for ptrdiff_t overflow.
18562 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18563 when a (possibly-narrower) signed value would do just as well.
18564 We prefer using signed arithmetic, to avoid comparison confusion.
18566 * alloc.c: Catch some string size overflows that we were missing.
18567 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18568 for convenience in STRING_BYTES_MAX.
18569 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18570 The definition here is exact; the one in lisp.h was approximate.
18571 (allocate_string_data): Check for string overflow. This catches
18572 some instances we weren't catching before. Also, it catches
18573 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18574 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18575 and ptrdiff_t and EMACS_INT are both 64 bits.
18577 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18578 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18579 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18581 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18583 * alloc.c (Fmake_string): Check for out-of-range init.
18585 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18587 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18589 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18591 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18592 xg_get_default_scrollbar_width.
18594 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18595 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18596 (style_changed_cb): Call update_theme_scrollbar_width and call
18597 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18598 all frames (Bug#8505).
18599 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18600 Call gtk_window_set_resizable if HAVE_GTK3.
18601 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18602 and height if HAVE_GTK3 (Bug#8505).
18603 (scroll_bar_width_for_theme): New variable.
18604 (update_theme_scrollbar_width): New function.
18605 (xg_get_default_scrollbar_width): Move code to
18606 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18607 (xg_initialize): Call update_theme_scrollbar_width.
18609 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18611 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18613 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18615 * frame.c (make_frame): Call other_buffer_safely instead of
18618 * window.c (temp_output_buffer_show): Call display_buffer with
18619 second argument Vtemp_buffer_show_specifiers and reset latter
18620 immediately after the call.
18621 (Vtemp_buffer_show_specifiers): New variable.
18622 (auto_window_vscroll_p, next_screen_context_lines)
18623 (Vscroll_preserve_screen_position): Remove leading asterisks from
18626 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18628 Fix minor problems found by GCC 4.6.0 static checking.
18629 * buffer.c (Qclone_number): Remove for now, as it's unused.
18630 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18631 (record_buffer): Remove unused local.
18632 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18633 (set_frame_buffer_list): Remove; unused.
18634 * frame.h (other_visible_frames): Remove decl.
18635 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18636 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18637 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18639 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18640 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18641 Define only if HAVE_GPM.
18642 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18643 (update_hints_inhibit): Remove; never set. All uses removed.
18644 * widgetprv.h (emacsFrameClassRec): Remove decl.
18645 * window.c (delete_deletable_window): Now returns void, since it
18646 wasn't returning anything.
18647 (compare_window_configurations): Remove unused locals.
18648 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18649 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18650 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18651 the same widths as pointers. This follows up on the 2011-05-06 patch.
18652 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18653 * xterm.h: Likewise.
18654 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18656 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18658 * makefile.w32-in: Update dependencies.

19116 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
19117 New error handlers.
19118 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
19119 Obey Vx_select_enable_clipboard_manager. Catch errors in
19120 x_clipboard_manager_save (Bug#8779).
19121 (Vx_select_enable_clipboard_manager): New variable.
19122 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19124 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19126 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19128 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19130 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
19131 in the current matrix if keep_current_p is non-zero.
19133 2011-06-04 Eli Zaretskii <eliz@gnu.org>
19135 * bidi.c (bidi_level_of_next_char): Fix last change.
19137 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19139 Support bidi reordering of text covered by display properties.
19141 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19142 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19143 (bidi_cache_search, bidi_cache_iterator_state)
19144 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19145 (bidi_level_of_next_char, bidi_move_to_visually_next):
19146 Support character positions inside a run of characters covered by a
19148 (bidi_paragraph_init, bidi_resolve_explicit_1)
19149 (bidi_level_of_next_char): Call bidi_fetch_char and
19150 bidi_fetch_char_advance instead of FETCH_CHAR and
19151 FETCH_CHAR_ADVANCE.
19152 (bidi_init_it): Initialize new members.
19153 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19155 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19156 instead of using explicit *_CHAR codes.
19157 (bidi_resolve_explicit, bidi_resolve_weak):
19158 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19159 bidirectional text is supported only in multibyte buffers.
19160 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19161 it to initialize the frame_window_p member of struct bidi_it.
19162 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19163 (bidi_resolve_explicit, bidi_resolve_weak)

19165 bidi_it->nchars is non-positive.
19166 (bidi_level_of_next_char): Don't try to lookup the cache for the
19167 next/previous character if nothing is cached there yet, or if we
19168 were just reseat()'ed to a new position.
19170 * xdisp.c (set_cursor_from_row): Set start and stop points
19171 according to the row's direction when priming the loop that looks
19172 for the glyph on which to display cursor.
19173 (single_display_spec_intangible_p): Function deleted.
19174 (display_prop_intangible_p): Reimplement to call
19175 handle_display_spec instead of single_display_spec_intangible_p.
19176 Accept 3 additional arguments needed by handle_display_spec.
19177 This fixes incorrect cursor motion across display property with complex
19178 values: lists, `(when COND...)' forms, etc.
19179 (single_display_spec_string_p): Support property values that are
19180 lists with the argument STRING its top-level element.
19181 (display_prop_string_p): Fix the condition for processing a
19182 property that is a list to be consistent with handle_display_spec.
19183 (handle_display_spec): New function, refactored from the
19184 last portion of handle_display_prop.
19185 (compute_display_string_pos): Accept additional argument
19186 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19187 value of a `display' property is a "replacing spec".
19188 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19189 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19190 the display property, but just return a value indicating whether
19191 the display property will replace the characters it covers.
19192 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19193 frame_window_p members of struct bidi_it.
19194 (compute_display_string_pos, compute_display_string_end):
19196 (push_it): Accept second argument POSITION, where pop_it should
19197 jump to continue iteration.
19198 (reseat_1): Initialize bidi_it.disp_pos.
19200 * keyboard.c (adjust_point_for_property): Adjust the call to
19201 display_prop_intangible_p to its new signature.
19203 * dispextern.h (struct bidi_it): New member frame_window_p.
19204 (bidi_init_it): Update prototypes.
19205 (display_prop_intangible_p): Update prototype.
19206 (compute_display_string_pos, compute_display_string_end):
19207 Declare prototypes.
19208 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19211 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19213 Malloc failure behavior now depends on size of allocation.
19214 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19215 * lisp.h: Change signatures accordingly.
19216 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19217 All callers changed. (Bug#8762)
19219 * gnutls.c: Use Emacs's memory allocators.
19220 Without this change, the gnutls library would invoke malloc etc.
19221 directly, which causes problems on non-SYNC_INPUT hosts, and which
19222 runs afoul of improving memory_full behavior. (Bug#8761)
19223 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19224 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19225 xfree instead of the default malloc, realloc, free.
19226 (Fgnutls_boot): No need to check for memory allocation failure,
19227 since xmalloc does that for us.
19229 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19230 * category.c (hash_get_category_set):
19231 * ccl.c (ccl_driver):
19232 * charset.c (Fdefine_charset_internal):
19233 * charset.h (struct charset.hash_index):
19234 * composite.c (get_composition_id, gstring_lookup_cache)
19235 (composition_gstring_put_cache):
19236 * composite.h (struct composition.hash_index):
19237 * dispextern.h (struct image.hash):
19238 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19239 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
19240 (hashfn_equal, hashfn_user_defined, make_hash_table)
19241 (maybe_resize_hash_table, hash_lookup, hash_put)
19242 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19243 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19244 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19245 * image.c (make_image, search_image_cache, lookup_image)
19246 (xpm_put_color_table_h):
19247 * lisp.h (struct Lisp_Hash_Table):
19248 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19249 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19250 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19251 * alloc.c (allocate_vectorlike):
19252 Check for overflow in vector size calculations.
19253 * ccl.c (ccl_driver):
19254 Check for overflow when converting EMACS_INT to int.
19255 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19256 need to be updated by these changes.
19257 * fns.c (make_hash_table, maybe_resize_hash_table):
19258 Check for integer overflow with large hash tables.
19259 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19260 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19261 (SXHASH_REDUCE): New macro.
19262 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19263 Use it instead of discarding useful hash info with large hash values.
19264 (sxhash_float): New function.
19265 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19266 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19267 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19268 Rewrite to use FIXNUM_BITS, as this simplifies things.
19269 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19270 Adjust signatures to match updated version of code.
19271 (consing_since_gc): Now EMACS_INT, since a single hash table can
19272 use more than INT_MAX bytes.
19274 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19276 Make it possible to build with GCC-4.6+ -O2 -flto.
19278 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19280 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19282 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19283 Call minibuffer-inactive-mode.
19285 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19287 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19288 Update dependencies.
19290 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19292 * data.c (init_data): Remove code for UTS, this system is not
19295 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19297 Don't force ./temacs to start in terminal mode.
19299 * frame.c (make_initial_frame): Initialize faces in all cases, not
19300 only when CANNOT_DUMP is defined.
19301 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19303 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19305 * dispnew.c (add_window_display_history): Use const for the string
19306 pointer. Remove declaration, not needed.
19308 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19310 Use 'inline', not 'INLINE'.
19311 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19312 * alloc.c, fontset.c (INLINE): Remove.
19313 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19314 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19315 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19316 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19317 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19319 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19321 Make it possible to run ./temacs.
19323 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19324 syms_of_callproc does the same thing. Remove test for
19325 "initialized", do it in the caller.
19326 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19328 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19330 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19331 (read_minibuf): Use get_minibuffer.
19332 (syms_of_minibuf): Use DEFSYM.
19333 (Qmetadata): New var.
19334 * data.c (Qbuffer): Don't make it static.
19335 (syms_of_data): Use DEFSYM.
19337 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19339 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19340 (CCL_CODE_MIN): New macro.
19342 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19344 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19346 * eval.c (Qdebug): Now static.
19347 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19348 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19349 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19351 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19353 * image.c: Various fixes to ImageMagick code comments.
19354 (Fimagemagick_types): Doc fix.
19356 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19358 Minor fixes prompted by GCC 4.6.0 warnings.
19360 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19362 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19363 (x_clipboard_manager_save_all): Move extern decl to ...
19364 * xterm.h: ... here, so that it can be checked for consistency.
19366 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19368 * xselect.c (x_clipboard_manager_save_frame)
19369 (x_clipboard_manager_save_all): New functions.
19370 (Fx_clipboard_manager_save): Lisp function deleted.
19372 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19373 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19375 * xterm.h: Update prototype.
19377 2011-05-28 William Xu <william.xwl@gmail.com>
19379 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19380 exiting (Bug#8239).
19382 2011-05-28 Jim Meyering <meyering@redhat.com>
19384 Avoid a sign-extension bug in crypto_hash_function.
19385 * fns.c (to_uchar): Define.
19386 (crypto_hash_function): Use it to convert some newly-signed
19387 variables to unsigned, to avoid sign-extension bugs. For example,
19388 without this change, (md5 "truc") would evaluate to
19389 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19390 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19391 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19393 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19395 Integer overflow fixes.
19397 * dbusbind.c: Serial number integer overflow fixes.
19398 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19399 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19400 to hold a serial number that is too large for a fixnum.
19401 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19402 Check for serial numbers out of range. Decode any serial number
19403 that was so large that it became a float. (Bug#8722)
19405 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19406 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19407 Use XFASTINT rather than XUINT when numbers are nonnegative.
19408 (xd_append_arg, Fdbus_method_return_internal):
19409 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19410 arguments, check that Lisp number is nonnegative, rather than
19411 silently wrapping negative numbers around. (Bug#8722)
19412 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19415 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19417 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19419 ccl: Add integer overflow checks.
19420 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19421 (IN_INT_RANGE): New macros.
19422 (ccl_driver): Use them to check for integer overflow when
19423 decoding a CCL program. Many of the new checks are whether XINT (x)
19424 fits in int; it doesn't always, on 64-bit hosts. The new version
19425 doesn't catch all possible integer overflows, but it's an
19426 improvement. (Bug#8719)
19428 * alloc.c (make_event_array): Use XINT, not XUINT.
19429 There's no need for unsigned here.
19431 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19432 This follows up to the 2011-05-06 change that substituted uintptr_t
19433 for EMACS_INT. This case wasn't caught back then.
19435 Rework Fformat to avoid integer overflow issues.
19436 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19437 now (part of C89). Include <verify.h>.
19438 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19439 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19440 (Fformat): Avoid the prepass trying to compute sizes; it was only
19441 approximate and thus did not catch overflow reliably. Instead, walk
19442 through the format just once, formatting and computing sizes as we go,
19443 checking for integer overflow at every step, and allocating a larger
19444 buffer as needed. Keep track separately whether the format is
19445 multibyte. Keep only the most-recently calculated precision, rather
19446 than them all. Record whether each argument has been converted to
19447 string. Use EMACS_INT, not int, for byte and char and arg counts.
19448 Support field widths and precisions larger than INT_MAX. Avoid
19449 sprintf's undefined behavior with conversion specifications such as %#d
19450 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19451 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19452 formatting out-of-range floating point numbers with int
19453 formats. (Bug#8668)
19455 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19457 * data.c: Avoid integer truncation in expressions involving floats.
19458 * data.c: Include <intprops.h>.
19459 (arith_driver): When there's an integer overflow in an expression
19460 involving floating point, convert the integers to floating point
19461 so that the resulting value does not suffer from catastrophic
19462 integer truncation. For example, on a 64-bit host (* 4
19463 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19464 Do not rely on undefined behavior after integer overflow.
19466 merge count_size_as_multibyte, parse_str_to_multibyte
19467 * character.c, character.h (count_size_as_multibyte):
19468 Rename from parse_str_to_multibyte; all uses changed.
19469 Check for integer overflow.
19470 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19471 since it's now a duplicate of the other. This is more of
19472 a character than a buffer op, so better that it's in character.c.
19473 * fns.c, print.c: Adjust to above changes.
19475 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19477 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19479 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19481 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19482 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19483 (x_clipboard_manager_save): Now static.
19484 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19486 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19487 (crypto_hash_function): Now static.
19488 Fix pointer signedness problems. Avoid unnecessary initializations.
19490 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19492 * termhooks.h (Vselection_alist): Make it terminal-local.
19494 * terminal.c (create_terminal): Initialize it.
19496 * xselect.c: Support for clipboard managers.
19497 (Vselection_alist): Move to termhooks.h as terminal-local var.
19498 (LOCAL_SELECTION): New macro.
19499 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19500 (symbol_to_x_atom): Remove gratuitous arg.
19501 (x_handle_selection_request, lisp_data_to_selection_data)
19502 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19503 (x_own_selection, x_get_local_selection, x_convert_selection):
19504 New arg, specifying work frame. Use terminal-local Vselection_alist.
19505 (some_frame_on_display): Delete unused function.
19506 (Fx_own_selection_internal, Fx_get_selection_internal)
19507 (Fx_disown_selection_internal, Fx_selection_owner_p)
19508 (Fx_selection_exists_p): New optional frame arg.
19509 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19510 (x_handle_selection_clear): Don't treat other terminals with the
19511 same keyboard specially. Use the terminal-local Vselection_alist.
19512 (x_clear_frame_selections): Use Frun_hook_with_args.
19514 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19516 * xterm.h: Add support for those atoms.
19518 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19520 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19521 (converted_selections, conversion_fail_tag): New global variables.
19522 (x_selection_request_lisp_error): Free the above.
19523 (x_get_local_selection): Remove unnecessary code.
19524 (x_reply_selection_request): Args changed; handle arbitrary array
19525 of converted selections stored in converted_selections.
19526 Separate the XChangeProperty and SelectionNotify steps.
19527 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19528 (x_convert_selection): New function.
19529 (x_handle_selection_event): Simplify.
19530 (x_get_foreign_selection): Don't ignore incoming requests while
19531 waiting for an answer; this will fail when we implement
19532 SAVE_TARGETS, and seems unnecessary anyway.
19533 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19534 (Vx_sent_selection_functions): Doc fix.
19536 2011-05-26 Leo Liu <sdl.web@gmail.com>
19538 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19540 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19542 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19544 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19545 for fringe update if it has periodic bitmap.
19546 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19547 and fringe_bitmap_periodic_p.
19549 * fringe.c (get_fringe_bitmap_data): New function.
19550 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19551 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19552 row. Mark glyph row for fringe update if periodicity changed.
19554 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19555 for fringe update unless it has periodic bitmap.
19557 2011-05-25 Kenichi Handa <handa@m17n.org>
19559 * xdisp.c (get_next_display_element): Set correct it->face_id for
19560 a static composition.
19562 2011-05-24 Leo Liu <sdl.web@gmail.com>
19565 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19567 * fns.c (crypto_hash_function, Fsha1): New function.
19568 (Fmd5): Use crypto_hash_function.
19569 (syms_of_fns): Add Ssha1.
19571 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19573 * gnutls.c: Remove unused macros.
19574 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19575 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19576 Remove macros that are defined and never used.
19577 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19579 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19581 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19582 (Fx_get_selection_internal): Minor cleanup.
19583 (Fx_own_selection_internal): Rename arguments for consistency with
19586 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19588 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19590 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19592 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19594 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19596 * dispnew.c (scrolling_window): Don't exclude the case that the
19597 last enabled row in the desired matrix touches the bottom boundary.
19599 2011-05-21 Glenn Morris <rgm@gnu.org>
19601 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19602 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19603 and add some more files.
19605 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19607 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19608 report_file_error introduced by the change from 2011-05-07.
19610 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19612 * systime.h (Time): Define only if emacs is defined.
19613 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19614 where the include path doesn't have X11/X.h by default. See
19615 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19617 2011-05-20 Kenichi Handa <handa@m17n.org>
19619 * composite.c (find_automatic_composition): Fix previous change.
19621 2011-05-20 Glenn Morris <rgm@gnu.org>
19623 * lisp.mk: New file, split from Makefile.in.
19624 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19625 (shortlisp): Remove.
19626 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19628 2011-05-19 Glenn Morris <rgm@gnu.org>
19630 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19631 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19632 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19633 (lisp): Set the order to that of loadup.el.
19634 (shortlisp): Make it a copy of $lisp.
19635 (SOME_MACHINE_LISP): Remove.
19636 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19637 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19639 2011-05-18 Kenichi Handa <handa@m17n.org>
19641 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19642 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19643 (find_automatic_composition): Mostly rewrite for efficiency.
19645 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19647 * makefile.w32-in: Update dependencies.
19649 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19651 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19652 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19654 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19656 Fix some integer overflow issues, such as string length overflow.
19658 * insdel.c (count_size_as_multibyte): Check for string overflow.
19660 * character.c (lisp_string_width): Check for string overflow.
19661 Use EMACS_INT, not int, for string indexes and lengths; in
19662 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19663 the resulting string length overflows an EMACS_INT; instead,
19664 report a string overflow if no precision given. When checking for
19665 precision exhaustion, use a check that cannot possibly have
19666 integer overflow. (Bug#8675)
19667 * character.h (lisp_string_width): Adjust to new signature.
19669 * alloc.c (string_overflow): New function.
19670 (Fmake_string): Use it. This doesn't change behavior, but saves
19671 a few bytes and will simplify future changes.
19672 * character.c (string_escape_byte8): Likewise.
19673 * lisp.h (string_overflow): New decl.
19675 Fixups, following up to the user-interface timestamp change.
19676 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19677 for UI timestamps, instead of unsigned long.
19678 * msdos.c (mouse_get_pos): Likewise.
19679 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19680 * w32gui.h (Time): Define by including "systime.h" rather than by
19681 declaring it ourselves. (Bug#8664)
19683 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19684 * image.c (clear_image_cache): Likewise.
19686 * term.c (term_mouse_position): Don't assume time_t wraparound.
19688 Be more systematic about user-interface timestamps.
19689 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19690 and sometimes 'EMACS_UINT', to represent these timestamps.
19691 This change causes it to use 'Time' uniformly, as that's what X uses.
19692 This makes the code easier to follow, and makes it easier to catch
19693 integer overflow bugs such as Bug#8664.
19694 * frame.c (Fmouse_position, Fmouse_pixel_position):
19695 Use Time, not unsigned long, for user-interface timestamps.
19696 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19697 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19698 * keyboard.h (last_event_timestamp): Likewise.
19699 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19700 * menu.h (xmenu_show): Likewise.
19701 * term.c (term_mouse_position): Likewise.
19702 * termhooks.h (struct input_event.timestamp): Likewise.
19703 (struct terminal.mouse_position_hook): Likewise.
19704 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19705 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19706 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19707 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19708 what it was before.
19709 * menu.h, termhooks.h: Include "systime.h", for Time.
19711 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19712 Don't assume that the difference between two unsigned long values
19713 can fit into an integer. At this point, we know button_down_time
19714 <= event->timestamp, so the difference must be nonnegative, so
19715 there's no need to cast the result if double-click-time is
19716 nonnegative, as it should be; check that it's nonnegative, just in
19717 case. This bug is triggered when events are more than 2**31 ms
19718 apart (about 25 days). (Bug#8664)
19720 * xselect.c (last_event_timestamp): Remove duplicate decl.
19721 (x_own_selection): Remove needless cast to unsigned long.
19723 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19724 that always fit in int. Use a sentinel instead of a counter, to
19725 avoid a temp and to allay GCC's concerns about possible int overflow.
19726 * frame.h (struct frame): Use int for menu_bar_items_used
19727 instead of EMACS_INT, since it always fits in int.
19729 * menu.c (grow_menu_items): Check for int overflow.
19731 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19733 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19734 Before, the code was not consistent. These values cannot exceed
19735 2**31 - 1 so there's no need to make them unsigned.
19736 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19737 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19738 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19740 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19742 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19743 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19744 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19745 presumably because the widths might not match.
19747 * window.c (size_window): Avoid needless test at loop start.
19749 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19751 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19753 2011-05-12 Drew Adams <drew.adams@oracle.com>
19755 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19757 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19759 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19760 `width' to `bar_area_x' and `bar_area_width', respectively.
19761 (x_scroll_run): Take account of fringe background extension.
19763 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19764 Rename local vars `left' and `width' to `bar_area_x' and
19765 `bar_area_width', respectively.
19766 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19767 background extension.
19769 2011-05-10 Jim Meyering <meyering@redhat.com>
19771 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19773 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19775 * image.c (Finit_image_library): Return t for built-in image types,
19776 like pbm and xbm. (Bug#8640)
19778 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19780 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19782 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19784 * w32console.c (Fset_screen_color): Doc fix.
19785 (Fget_screen_color): New function.
19786 (syms_of_ntterm): Defsubr it.
19788 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19789 unlink the temporary file if Fcall_process didn't create it in the
19791 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19792 child process will be redirected to a file specified with `:file'.
19793 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19794 cue to call_process_cleanup not to close that handle.
19796 2011-05-07 Ben Key <bkey76@gmail.com>
19798 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19799 one of two shell specific rules, either bootstrap-temacs-CMD or
19800 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19801 to the previous implementation of the bootstrap-temacs rule.
19802 The bootstrap-temacs-CMD rule is similar to the previous
19803 implementation of the bootstrap-temacs rule except that it
19804 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19807 These changes, along with some changes to nt/configure.bat,
19808 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19809 earlier fix to add support for --cflags and --ldflags options
19810 that include quotes so that it works whether make uses cmd or
19813 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19815 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19816 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19818 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19819 a string. Handle both cases.
19820 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19821 (Fdbus_register_method): Use Qinvalid_function.
19823 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19825 * makefile.w32-in: Update dependencies.
19826 (LISP_H): Add inttypes.h and stdin.h.
19827 (PROCESS_H): Add unistd.h.
19829 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19831 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19832 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19834 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19836 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19838 * term.c (vfatal): Remove stray call to va_end.
19839 It's not needed and the C Standard doesn't allow it here anyway.
19841 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19842 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19844 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19847 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19849 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19851 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19853 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19855 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19857 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19858 * charset.c (Fdefine_charset_internal): Don't initialize
19859 charset.code_space[15]. The value was garbage, on hosts with
19860 32-bit int (Bug#8600).
19862 * lread.c (read_integer): Be more consistent with string-to-number.
19863 Use string_to_number to do the actual conversion; this avoids
19864 rounding errors and fixes some other screwups. Without this fix,
19865 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19866 (digit_to_number): Move earlier, for benefit of read_integer.
19867 Return -1 if the digit is out of range for the base, -2 if it is
19868 not a digit in any supported base. (Bug#8602)
19870 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19872 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19873 to match comment at start of function. This also removes a
19874 GCC warning about overflow in a 32+64-bit port.
19876 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19878 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19879 Reported by Stefan Monnier in
19880 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19881 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19882 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19884 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19885 (EMACS_UINTPTR): Likewise, with uintptr_t.
19887 * lisp.h: Prefer 64-bit EMACS_INT if available.
19888 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19889 on 32-bit hosts that have 64-bit int, so that they can access
19891 However, temporarily disable this change unless the temporary
19892 symbol WIDE_EMACS_INT is defined.
19894 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19896 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19897 This removes an assumption that EMACS_INT and long are the same
19898 width as pointers. The assumption is true for Emacs porting targets
19899 now, but we want to make other targets possible.
19900 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19901 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19902 In the rest of the code, change types of integers that hold casted
19903 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19904 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19905 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19906 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19907 No need to cast type when ORing.
19908 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19909 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19910 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19911 assume EMACS_INT is the same width as char *.
19912 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19913 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19914 Remove no-longer-needed casts.
19915 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19916 (xg_tool_bar_help_callback, xg_make_tool_item):
19917 Use EMACS_INTPTR to hold an integer
19918 that will be cast to void *; this can avoid a GCC warning
19919 if EMACS_INT is not the same width as void *.
19920 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19921 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19922 (current_message_1, set_message_1):
19923 Use a local to convert to proper width without a cast.
19924 * xmenu.c (dialog_selection_callback): Likewise.
19926 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19927 Also, don't assume VALBITS / RAND_BITS is less than 5,
19928 and don't rely on undefined behavior when shifting a 1 left into
19930 * lisp.h (get_random): Change signature to match.
19932 * lread.c (hash_string): Use size_t, not int, for hash computation.
19933 Normally we prefer signed values; but hashing is special, because
19934 it's better to use unsigned division on hash table sizes so that
19935 the remainder is nonnegative. Also, size_t is the natural width
19936 for hashing into memory. The previous code used 'int', which doesn't
19937 retain enough info to hash well into very large tables.
19938 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19940 * dbusbind.c: Don't possibly lose pointer info when converting.
19941 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19942 Use XPNTR rather than XHASH, so that the high-order bits of
19943 the pointer aren't lost when converting through void *.
19945 * eval.c (Fautoload): Don't double-shift a pointer.
19947 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19949 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19951 * gnutls.c (DEF_GNUTLS_FN):
19952 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19954 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19956 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19959 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19961 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19962 New version that can reserve upto 2GB of heap space.
19964 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19966 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

20030 * process.c: Include lisp.h before w32.h, not after.
20031 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20032 instead of gnutls_record_check_pending.

20036 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20038 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

20084 rather than `XVECTOR (FOO)->size'.
20086 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20087 inttypes.h, as a gnulib replacement is used if it not available in
20090 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20092 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20093 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20094 of MOST_POSITIVE_FIXNUM. (Bug#8528)

20107 aborting when %lld or %lll format is passed.
20108 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20109 %llo or %llx format is passed. (Bug#8545)
20111 * window.c (window_scroll_line_based): Use a marker instead of
20112 simple variables to record original value of point. (Bug#7952)
20114 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20115 produced by %s or %c overflows available buffer space. (Bug#8545)
20117 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20119 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20120 (SIZE_MAX): Move defn after all includes, as they might #define it.
20122 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20124 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20126 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20128 * keyboard.c (Qdelayed_warnings_hook): Define.
20129 (command_loop_1): Run `delayed-warnings-hook'
20130 if Vdelayed_warnings_list is non-nil.
20131 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20132 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20134 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20136 * doprnt.c (doprnt): Don't return value smaller than the buffer
20137 size if the message was truncated. (Bug#8545).
20139 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20141 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20142 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20144 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20146 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20148 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20150 * makefile.w32-in: Update dependencies.
20152 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20154 Improve `doprnt' and its usage. (Bug#8545)
20155 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20156 `format_end'. Remove support for %l as a conversion specifier.
20157 Don't use xrealloc. Improve diagnostics when the %l size modifier
20158 is used. Update the commentary.
20160 * eval.c (verror): Simplify calculation of size_t.
20162 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20165 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20167 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20170 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20172 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20173 This makes this file independent of the recent pseudovector change.
20175 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20177 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20179 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20180 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20181 Remove unused local.
20182 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20184 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20185 GCC 4.6.0 optimizes based on type-based alias analysis.
20186 For example, if b is of type struct buffer * and v of type struct
20187 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20188 != &v->size, and therefore "v->size = 1; b->size = 2; return
20189 v->size;" must therefore return 1. This assumption is incorrect
20190 for Emacs, since it type-puns struct Lisp_Vector * with many other
20191 types. To fix this problem, this patch adds a new type struct
20192 vectorlike_header that documents the constraints on layout of vectors
20193 and pseudovectors, and helps optimizing compilers not get fooled
20194 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20195 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20196 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20198 (XSETPVECTYPE): Rewrite in terms of new macro.
20199 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20200 This is a bit clearer, and further avoids the possibility of
20201 undesirable aliasing.
20202 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20203 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20204 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20205 since Lisp_Subr is a special case (no "next" field).
20206 (ASIZE): Now uses header.size rather than size.
20207 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20208 to avoid the hassle of writing XVECTOR (foo)->header.size.
20209 (struct vectorlike_header): New type.
20210 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20211 object, to help avoid aliasing.
20212 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20213 (SUBRP): Likewise, since Lisp_Subr is a special case.
20214 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20215 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20216 (struct Lisp_Hash_Table): Combine first two members into a single
20217 struct vectorlike_header member. All uses of "size" and "next" members
20218 changed to be "header.size" and "header.next".
20219 * buffer.h (struct buffer): Likewise.
20220 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20221 * frame.h (struct frame): Likewise.
20222 * process.h (struct Lisp_Process): Likewise.
20223 * termhooks.h (struct terminal): Likewise.
20224 * window.c (struct save_window_data, struct saved_window): Likewise.
20225 * window.h (struct window): Likewise.
20226 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20227 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20228 * buffer.c (init_buffer_once): Likewise.
20229 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20231 * process.c (Fformat_network_address): Use local var for size,
20234 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20236 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20237 * data.c (atof): Remove decl; no longer used or needed.
20238 (digit_to_number): Move to lread.c.
20239 (Fstring_to_number): Use new string_to_number function, to be
20240 consistent with how the Lisp reader treats infinities and NaNs.
20241 Do not assume that floating-point numbers represent EMACS_INT
20242 without losing information; this is not true on most 64-bit hosts.
20243 Avoid double-rounding errors, by insisting on integers when
20244 parsing non-base-10 numbers, as the documentation specifies.
20245 * lisp.h (string_to_number): New decl, replacing ...
20246 (isfloat_string): Remove.
20247 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20248 (read1): Do not accept +. and -. as integers; this
20249 appears to have been a coding error. Similarly, do not accept
20250 strings like +-1e0 as floating point numbers. Do not report
20251 overflow for integer overflows unless the base is not 10 which
20252 means we have no simple and reliable way to continue.
20253 Break out the floating-point parsing into a new
20254 function string_to_number, so that Fstring_to_number parses
20255 floating point numbers consistently with the Lisp reader.
20256 (digit_to_number): Move here from data.c. Make it static inline.
20257 (E_CHAR, EXP_INT): Remove, replacing with ...
20258 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20259 (string_to_number): New function, replacing isfloat_string.
20260 This function checks for valid syntax and produces the resulting
20261 Lisp float number too. Rework it so that string-to-number
20262 no longer mishandles examples like "1.0e+". Use strtoumax,
20263 so that overflow for non-base-10 numbers is reported only when
20264 there's no portable and simple way to convert to floating point.
20266 * textprop.c (set_text_properties_1): Rewrite for clarity,
20267 and to avoid GCC warning about integer overflow.
20269 * intervals.h (struct interval): Use EMACS_INT for members
20270 where EMACS_UINT might cause problems. See
20271 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20272 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20273 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20275 (offset_intervals): Tell GCC not to worry about length overflow
20276 when negating a negative length.
20278 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20279 (overrun_check_free): Likewise.
20281 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20282 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20285 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20286 (gnutls_make_error): Rename local to avoid shadowing.
20287 (gnutls_emacs_global_deinit): ifdef out; not used.
20288 (Fgnutls_boot): Use const for pointer to readonly storage.
20289 Comment out unused local. Fix pointer signedness problems.
20291 * lread.c (openp): Don't stuff size_t into an 'int'.
20292 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20293 about possible signed overflow.
20295 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20296 (GDK_KEY_g): Don't define if already defined.
20297 (xg_prepare_tooltip): Avoid pointer signedness problem.
20298 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20300 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20301 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20303 * xfns.c (Fx_window_property): Simplify a bit,
20304 to make a bit faster and to avoid GCC 4.6.0 warning.
20305 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20307 * fns.c (internal_equal): Don't assume size_t fits in int.
20309 * alloc.c (compact_small_strings): Tighten assertion a little.
20311 Replace pEd with more-general pI, and fix some printf arg casts.
20312 * lisp.h (pI): New macro, generalizing old pEd macro to other
20313 conversion specifiers. For example, use "...%"pI"d..." rather
20314 than "...%"pEd"...".
20315 (pEd): Remove. All uses replaced with similar uses of pI.
20316 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20317 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20318 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20319 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20320 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20321 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20322 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20324 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20325 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20326 * print.c (safe_debug_print, print_object): Likewise.
20327 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20329 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20330 avoiding the 0 flag, which is not portable.
20331 * process.c (Fmake_network_process): Use pI to avoid cast.
20332 * region-cache.c (pp_cache): Likewise.
20333 * xdisp.c (decode_mode_spec): Likewise.
20334 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20335 behavior on 64-bit hosts with printf arg.
20336 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20337 (x_stop_queuing_selection_requests): Likewise.
20338 (x_get_window_property): Don't truncate byte count to an 'int'
20341 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20342 here, since it parses constructs like leading '-' and spaces,
20343 which are not wanted; and it overflows with large numbers.
20344 Instead, simply match F[0-9]+, which is what is wanted anyway.
20346 * alloc.c: Remove unportable assumptions about struct layout.
20347 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20348 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20349 (allocate_vectorlike, make_pure_vector): Use the new macros,
20350 plus offsetof, to remove unportable assumptions about struct layout.
20351 These assumptions hold on all porting targets that I know of, but
20352 they are not guaranteed, they're easy to remove, and removing them
20353 makes further changes easier.
20355 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20356 This doesn't fix a bug but makes the code clearer.
20357 (string_overrun_cookie): Now const. Use initializers that
20358 don't formally overflow signed char, to avoid warnings.
20359 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20360 can cause Emacs to crash when string overrun checking is enabled.
20361 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20362 multiple of sizeof (EMACS_INT); it need not be, if
20363 alignof(EMACS_INT) < sizeof (EMACS_INT).
20364 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20366 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20368 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20370 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20372 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20373 supposed to be handshaking. (Bug#8556)
20374 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20376 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
20378 * lisp.h (Qdebug): List symbol.
20379 * eval.c (Qdebug): Restore global linkage.
20380 * keyboard.c (debug-on-event): New variable.
20381 (handle_user_signal): Break into debugger when debug-on-event
20382 matches the current signal symbol.

20947 * xfaces.c (face_at_string_position):
20948 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

21137 to see whether these functions can be called from other modules.
21138 DEFUN now defines a static function. To make the function external
21139 so that it can be used in other C modules, use the new macro DEFUE.

21217 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21218 since callers should never pass a negative size.
21219 Change the signature to match that of plain 'read' and 'write'; see
21220 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21221 * lisp.h: Update prototypes of emacs_write and emacs_read.
21223 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21225 * xdisp.c (redisplay_window): Don't try to determine the character
21226 position of the scroll margin if the window start point w->startp
21227 is outside the buffer's accessible region. (Bug#8468)
21229 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21231 Fix write-region and its subroutines for buffers > 2GB.
21232 * fileio.c (a_write, e_write): Modify declaration of arguments and
21233 local variables to support buffers larger than 2GB.
21234 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21236 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21237 argument, local variables, and return value.
21239 * lisp.h: Update prototypes of emacs_write and emacs_read.
21241 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21243 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21245 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

21249 * xdisp.c (vmessage): Use a better test for character truncation.
21251 * charset.c (load_charset_map): <, not <=, for optimization,

21261 * callint.c (Fcall_interactively): <, not <=, for optimization.
21262 (Fcall_interactively): Count the number of arguments produced,
21263 not the number of arguments given. This is simpler and lets GCC
21264 4.6.0 generate slightly better code.
21266 * ftfont.c: Distingish more carefully between FcChar8 and char.
21267 The previous code passed unsigned char * to a functions like
21268 strlen and xstrcasecmp that expect char *, which does not
21269 conform to the C standard.
21270 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21271 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21272 char * when the C standard requires it.
21274 * keyboard.c (read_char): Remove unused var.
21276 * eval.c: Port to Windows vsnprintf (Bug#8435).
21277 Include <limits.h>.

21279 (verror): Do not give up if vsnprintf returns a negative count.
21280 Instead, grow the buffer. This ports to Windows vsnprintf, which
21281 does not conform to C99. Problem reported by Eli Zaretskii.
21282 Also, simplify the allocation scheme, by avoiding the need for
21283 calling realloc, and removing the ALLOCATED variable.
21285 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21287 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21288 But keep the doprint source code for now, as we might revamp it
21289 and use it again (Bug#8435).
21290 * lisp.h (doprnt): Remove.
21291 * Makefile.in (base_obj): Remove doprnt.o.
21292 * deps.mk (doprnt.o): Remove.
21294 error: Print 32- and 64-bit integers portably (Bug#8435).
21295 Without this change, on typical 64-bit hosts error ("...%d...", N)
21296 was used to print both 32- and 64-bit integers N, which relied on
21297 undefined behavior.
21298 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21299 * lisp.h (error, verror): Mark as printf-like functions.
21300 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21301 Report overflow in size calculations when allocating printf buffer.
21302 Do not truncate output string at its first null byte.
21303 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21304 Truncate the output at a character boundary, since vsnprintf does not
21306 * charset.c (check_iso_charset_parameter): Convert internal
21307 character to string before calling 'error', since %c now has the
21309 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21310 overflow when computing char to be passed to 'error'. Do not
21311 pass Lisp_Object to 'error'; pass the integer instead.
21312 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21313 formatted with plain %d.
21315 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21317 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21319 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21321 * xterm.c (x_catch_errors): Remove duplicate declaration.
21323 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21325 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21327 2011-04-10 Jim Meyering <meyering@redhat.com>
21329 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21330 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21331 return ssize_t not "int", and use size_t as the buffer length.
21332 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21333 * gnutls.h: Update declarations.
21334 * process.c (read_process_output): Use ssize_t, to match.
21335 (send_process): Likewise.

21339 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21341 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21343 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21344 Use unsigned char, to match FcChar8 type definition.
21346 * xterm.c (handle_one_xevent):
21347 * xmenu.c (create_and_show_popup_menu):
21348 * xselect.c (x_decline_selection_request)
21349 (x_reply_selection_request): Avoid type-punned deref of X events.
21351 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21353 Fix some uses of `int' instead of EMACS_INT.
21354 * search.c (string_match_1, fast_string_match)

21358 (Fmatch_data): Make some `int' variables be EMACS_INT.
21360 * xdisp.c (display_count_lines): 3rd argument and return value now
21361 EMACS_INT. All callers changed.
21362 (pint2hrstr): Last argument is now EMACS_INT.

21377 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21378 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21380 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21381 (encode_invocation_designation): Last argument P_NCHARS is now
21383 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21384 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21386 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21389 * ccl.c (Fccl_execute_on_string): Declare some variables
21392 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

21407 instead of using internal_with_output_to_temp_buffer.
21408 (Qhelp_form_show): New var.
21409 (syms_of_keyboard): Use DEFSYM macro.
21411 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21445 to system-supplied API.
21447 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21449 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21450 This avoids several warnings with gcc -Wstrict-overflow.
21451 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21452 directly, rather than having caller test rule sign. This avoids
21453 some unnecessary tests.
21454 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21455 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21456 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21458 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21459 (xfont_open): Avoid unnecessary tests.
21461 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21463 * composite.h, composite.c (composition_gstring_put_cache):
21464 Use EMACS_INT, not int, for length.

21467 breaking out part of COMPOSITION_DECODE_RULE.
21468 (COMPOSITION_DECODE_RULE): Use it.

21470 by using the new macro.
21472 * textprop.c (set_text_properties_1): Change while to do-while,
21473 since the condition is always true at first.
21475 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21476 (interval_deletion_adjustment): Return unsigned value.
21479 * process.c (list_processes_1, create_pty, read_process_output):

21491 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21492 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21493 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21495 * print.c (print_error_message): Avoid int overflow.
21497 * font.c (font_list_entities): Redo for clarity,
21498 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21500 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21501 (font_score): Avoid potential overflow in diff calculation.
21503 * fns.c (substring_both): Remove var that is set but not used.
21504 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21506 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21508 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21509 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21510 can always succeed if overflow has undefined behavior.
21512 * search.c (boyer_moore, wordify): Remove vars set but not used.
21513 (wordify): Omit three unnecessary tests.
21515 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21516 All callers changed. This avoids the need for an unused var.
21518 * casefiddle.c (casify_region): Remove var that is set but not used.
21520 * dired.c (file_name_completion): Remove var that is set but not used.
21522 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21524 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21525 (Finsert_file_contents): Remove unnecessary code checking fd.
21527 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21528 Check for integer overflow on size calculations.
21530 * buffer.c (Fprevious_overlay_change): Remove var that is set
21533 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21534 Remove vars that are set but not used.
21535 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21536 (timer_check_2): Mark vars as initialized.
21538 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21540 * image.c (lookup_image): Remove var that is set but not used.
21541 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21543 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21544 that are set but not used.
21546 * xfns.c (make_invisible_cursor): Don't return garbage
21547 if XCreateBitmapFromData fails (Bug#8410).
21549 * xselect.c (x_get_local_selection, x_handle_property_notify):
21550 Remove vars that are set but not used.
21552 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21553 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21555 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21556 Remove var that is set but not used.
21557 (scroll_bar_windows_size): Now size_t, not int.
21558 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21559 Check for overflow.
21561 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21562 (map_tty_color) [!defined MSDOS]: Likewise.
21564 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21566 * coding.c: Remove vars that are set but not used.
21567 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21568 All callers changed.

21570 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21571 (decode_coding_charset): Remove vars that are set but not used.
21573 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21574 that is set but not used.
21576 * print.c (print_object): Remove var that is set but not used.
21578 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21579 The gnulib version avoids calling malloc in the usual case,
21580 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21581 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21582 * filelock.c (current_lock_owner): Likewise.
21583 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21584 * sysdep.c: Include allocator.h, careadlinkat.h.
21585 (emacs_no_realloc_allocator): New static constant.
21586 (emacs_readlink): New function.
21587 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21588 ../lib/careadlinkat.h.
21590 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21592 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21593 first non-nil return value).
21595 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21597 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21598 if not defined (Bug#8403).

21607 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21608 and thereabouts. All callers changed.
21609 (get_per_char_metric): Remove parameter `f', unused since
21610 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21612 2011-04-02 Jim Meyering <meyering@redhat.com>
21614 do not dereference NULL upon failed strdup
21615 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21616 (ns_get_family): Likewise.
21618 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21620 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21622 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21624 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

21629 Add lexical binding.
21631 * window.c (Ftemp_output_buffer_show): New fun.

21642 (syms_of_lread): Declare `lexical-binding'.
21644 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21646 * keyboard.c (eval_dyn): New fun.
21647 (menu_item_eval_property): Use it.
21649 * image.c (parse_image_spec): Use Ffunctionp.
21651 * fns.c (concat, mapcar1): Accept byte-code-functions.
21653 * eval.c (Fsetq): Handle lexical vars.
21654 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21655 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21656 (FletX, Flet): Obey lexical binding.
21657 (Fcommandp): Handle closures.
21658 (Feval): New `lexical' arg.
21659 (eval_sub): New function extracted from Feval. Use it almost
21660 everywhere where Feval was used. Look up vars in lexical env.
21662 (Ffunctionp): Move from subr.el.
21663 (Ffuncall): Handle closures.
21664 (apply_lambda): Remove `eval_flags'.
21665 (funcall_lambda): Handle closures and new byte-code-functions.
21666 (Fspecial_variable_p): New function.
21667 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21668 but without exporting it to Lisp.
21670 * doc.c (Fdocumentation, store_function_docstring):
21671 * data.c (Finteractive_form): Handle closures.
21673 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21676 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21678 (exec_byte_code): New function extracted from Fbyte_code to handle new
21679 calling convention for byte-code-functions. Add new byte-codes.
21681 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21683 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21685 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21687 * xdisp.c (redisplay_internal): Fix prototype.

21691 * xdisp.c (SCROLL_LIMIT): New macro.
21692 (try_scrolling): Use it when setting scroll_limit.
21693 Limit scrolling to 100 screen lines.
21694 (redisplay_window): Even when falling back on "recentering",
21695 position point in the window according to scroll-conservatively,
21696 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21698 (try_scrolling): When point is above the window, allow searching
21699 as far as scroll_max, or one screenful, to compute vertical
21700 distance from PT to the scroll margin position. This prevents
21701 try_scrolling from unnecessarily failing when
21702 scroll-conservatively is set to a value slightly larger than the
21703 window height. Clean up the case of PT below the margin at bottom
21704 of window: scroll_max can no longer be INT_MAX. When aggressive
21705 scrolling is in use, don't let point enter the opposite scroll
21706 margin as result of the scroll.
21707 (syms_of_xdisp) <scroll-conservatively>: Document the
21708 threshold of 100 lines for never-recentering scrolling.

21715 (message_log_check_duplicate): Remove parameters `prev_bol' and
21716 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21717 (redisplay_internal): Remove parameter `preserve_echo_area',
21718 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21720 * indent.c (Fvertical_motion):
21721 * window.c (window_scroll_pixel_based, Frecenter):
21722 Don't pass `need_y_p' to `move_it_by_lines'.
21724 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21726 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21727 steal a few bits to be more compact.
21728 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21729 Remove unneeded casts.
21731 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21733 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21735 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21736 binding" message (bug#7967).
21738 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21740 Fix more problems found by GCC 4.6.0's static checks.
21742 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21743 Remove unused local var.
21745 * editfns.c (Fmessage_box): Remove unused local var.
21747 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21748 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21749 Omit unused local vars.
21750 * window.c (shrink_windows): Omit unused local var.
21751 * menu.c (digest_single_submenu): Omit unused local var.
21752 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21753 Omit unused local var.
21755 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21756 Don't assume string length fits in int.
21757 (keyremap_step, read_key_sequence): Use size_t for sizes.
21758 (read_key_sequence): Don't check last_real_key_start redundantly.
21760 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21761 instead of alloca (Bug#8344).
21763 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21764 (Fbacktrace_frame): Don't assume nframes fits in int.
21766 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21768 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21771 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21773 * cm.c (calccost): Turn while-do into do-while, for clarity.
21775 * keyboard.c (syms_of_keyboard): Use the same style as later
21776 in this function when indexing through an array. This also
21777 works around GCC bug 48267.
21779 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21781 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

21784 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21786 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21787 This avoids undefined behavior on integer overflow, and is a bit
21788 more convenient anyway since it is compared to a size_t variable.
21790 Variadic C functions now count arguments with size_t, not int.
21791 This avoids an unnecessary limitation on 64-bit machines, which
21792 caused (substring ...) to crash on large vectors (Bug#8344).
21793 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21794 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21795 All variadic functions and their callers changed accordingly.
21796 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21800 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21801 (funcall_lambda, mark_backtrace): Likewise.
21802 * fns.c (concat): Likewise.
21803 * frame.c (x_set_frame_parameters): Likewise.
21804 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21805 0 if not found, not -1. All callers changed.
21807 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21808 (stack_copy_size): Now size_t, not int.
21809 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21811 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21813 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21814 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21815 All callers changed.
21817 * lisp.h (multibyte_char_to_unibyte):
21818 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21819 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21821 * cmds.c (internal_self_insert):
21822 * editfns.c (general_insert_function):
21823 * keymap.c (push_key_description):
21824 * search.c (Freplace_match):
21825 * xdisp.c (message_dolog, set_message_1): All callers changed.
21827 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21829 * keyboard.c (safe_run_hook_funcall): New function.
21830 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21831 don't set the hook to nil, but remove the offending function instead.
21832 (Qcommand_hook_internal): Remove, unused.
21833 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21834 Vcommand_hook_internal.
21836 * eval.c (enum run_hooks_condition): Remove.
21837 (funcall_nil, funcall_not): New functions.
21838 (run_hook_with_args): Call each function through a `funcall' argument.
21839 Remove `cond' argument, now redundant.
21840 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21841 (Frun_hook_with_args_until_failure): Adjust accordingly.
21842 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21844 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21846 * dispextern.h (string_buffer_position): Remove declaration.
21848 * print.c (strout): Remove parameter `multibyte', unused since
21849 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21851 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21852 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21853 All callers changed.
21855 * w32.c (_wsa_errlist): Use braces for struct initializers.
21857 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21858 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21859 All callers changed.
21860 (string_buffer_position): Likewise. Also, make static (it's never
21861 used outside xdisp.c).
21862 (cursor_row_p): Remove parameter `w', unused since
21863 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21865 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21866 All callers changed.
21868 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21870 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21876 (ns_update_auto_hide_menu_bar): New functions.
21877 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21881 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21883 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21896 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21898 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21899 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21901 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21903 * w32.c (read_unc_volume): Use parameter `henum', instead of
21904 global variable `wget_enum_handle'.
21906 * keymap.c (describe_vector): Remove parameters `indices' and
21907 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21919 * xmenu.c (show_help_event, menu_help_callback):
21920 Adjust calls to `show_help_echo'.
21922 * gtkutil.c (xg_maybe_add_timer):
21923 * keyboard.c (readable_events):
21924 * process.c (wait_reading_process_output):
21925 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21927 * insdel.c (adjust_markers_gap_motion):
21928 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

22002 2011-03-23 Julien Danjou <julien@danjou.info>
22004 * term.c (Fsuspend_tty, Fresume_tty):
22005 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22006 * window.c (temp_output_buffer_show):

22012 * cmds.c (internal_self_insert):
22013 * callint.c (Fcall_interactively):
22014 * buffer.c (Fkill_all_local_variables):
22015 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22017 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22018 unconditionally since it does the check itself.
22020 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22022 Fix more problems found by GCC 4.5.2's static checks.
22024 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22025 the first time through the loop, since we know p0 < p1 then.
22026 This also avoids a gcc -Wstrict-overflow warning.
22028 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22029 leading to a memory leak, possible in functions like
22030 load_charset_map_from_file that can allocate an unbounded number
22031 of objects (Bug#8318).
22033 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22034 that could (at least in theory) be that large.
22036 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22037 This is less likely to overflow, and avoids undefined behavior if
22038 overflow does occur. All callers changed. Use strtoul to scan
22039 for the unsigned long integer.
22040 (pint2hrstr): Simplify and tune code slightly.
22041 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22049 This also avoids a warning with gcc -Wstrict-overflow.
22051 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22054 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22056 * process.c (Fmake_network_process): Use socklen_t, not int,
22057 where POSIX says socklen_t is required in portable programs.
22058 This fixes a porting bug on hosts like 64-bit HP-UX, where
22059 socklen_t is wider than int (Bug#8277).
22060 (Fmake_network_process, server_accept_connection):
22061 (wait_reading_process_output, read_process_output):
22064 * process.c: Rename or move locals to avoid shadowing.
22065 (list_processes_1, Fmake_network_process):
22066 (read_process_output_error_handler, exec_sentinel_error_handler):
22067 Rename or move locals.
22068 (Fmake_network_process): Define label "retry_connect" only if needed.
22069 (Fnetwork_interface_info): Fix pointer signedness.

22071 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22072 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22074 Make tparam.h and terminfo.c consistent.
22075 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22076 Include tparam.h instead, since it declares them.
22077 * cm.h (PC): Remove extern decl; tparam.h now does this.
22078 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22079 * terminfo.c: Include tparam.h, to check interfaces.
22080 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22081 (tparam): Adjust signature to match interface in tparam.h;
22082 this removes some undefined behavior. Check that outstring and len
22083 are zero, which they always are with Emacs.
22084 * tparam.h (PC, BC, UP): New extern decls.
22086 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22087 (xftfont_open): Rename locals to avoid shadowing.
22089 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22090 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22091 (OTF_TAG_SYM): Omit macro if not needed.
22092 (ftfont_list): Remove unused local.
22093 (get_adstyle_property, ftfont_pattern_entity):
22094 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22095 Rename locals to avoid shadowing.
22097 * xfont.c (xfont_list_family): Mark var as initialized.
22099 * xml.c (make_dom): Now static.
22101 * composite.c (composition_compute_stop_pos): Rename local to
22103 (composition_reseat_it): Remove unused locals.
22104 (find_automatic_composition, composition_adjust_point): Likewise.
22105 (composition_update_it): Mark var as initialized.
22106 (find_automatic_composition): Mark vars as initialized,
22107 with a FIXME (Bug#8290).
22109 character.h: Rename locals to avoid shadowing.
22110 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22111 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22112 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22113 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22114 to avoid shadowing.
22116 * textprop.c (property_change_between_p): Remove; unused.
22118 * intervals.c (interval_start_pos): Now static.
22120 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
22122 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
22123 Rename locals to avoid shadowing.
22125 * sound.c (wav_play, au_play, Fplay_sound_internal):
22126 Fix pointer signedness.
22127 (alsa_choose_format): Remove unused local var.
22128 (wav_play): Initialize a variable to 0, to prevent undefined
22129 behavior (Bug#8278).
22131 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22133 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22135 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22136 clobbering (Bug#8298).
22137 * sysdep.c (sys_subshell): Likewise.
22138 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22140 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22141 This should get cleaned up, so that child_setup has the
22142 same signature on all platforms.
22144 * callproc.c (call_process_cleanup): Now static.
22145 (relocate_fd): Rename locals to avoid shadowing.
22147 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22149 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22150 not to be necessary, and produces flickering.
22152 2011-03-20 Glenn Morris <rgm@gnu.org>
22154 * config.in: Remove file.
22156 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22158 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22159 are now in src/globals.h.

22237 instead of using an uninitialized var.
22238 (font_sort_entities): Mark var as initialized.
22240 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.

22258 * lisp.h: ... to here, so that it can be checked.
22260 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
22261 (Fdefvar): Rewrite so as not to use empty "else".

22266 * callint.c (quotify_arg, quotify_args): Now static.
22267 (Fcall_interactively): Rename locals to avoid shadowing.

22275 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22276 some of which prompt warnings from gcc -Wbad-function-cast.
22277 (Fformat_time_string, Fencode_time, Finsert_char):
22278 (Ftranslate_region_internal, Fformat):
22279 Rename or remove local vars to avoid shadowing.

22306 (Fmemory_limit): Cast sbrk's returned value to char *.
22308 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22309 avoids undefined behavior in theory.
22311 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22313 Use functions, not macros, for up- and down-casing (Bug#8254).
22314 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22315 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22316 to use the following functions instead of these macros.
22317 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22318 EMACS_INT, since callers assume the returned value fits in int.
22319 (upcase1): Likewise, for UPCASE_TABLE.
22320 (uppercasep, lowercasep, upcase): New static inline functions.
22321 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22327 (regex_compile, re_search_2, re_match_2_internal):
22328 Remove unused local vars.

22330 which gcc can warn about.
22331 (regex_compile, re_match_2_internal): Mark locals as initialized.
22332 (RETALLOC_IF): Define only if needed.
22333 (WORDCHAR_P): Likewise. This one is never needed, but is used
22334 only in a comment talking about a compiler bug, so put inside
22335 the #if 0 of that comment.
22336 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22337 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22340 * search.c (boyer_moore): Rename locals to avoid shadowing.

22355 Rename locals to avoid shadowing.
22356 (Fvertical_motion): Mark locals as initialized.
22358 * casefiddle.c (casify_object, casify_region): Now static.
22359 (casify_region): Mark local as initialized.

22363 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22364 New macros, so that the caller can use some names other than
22365 gcpro1, gcpro2, etc.
22366 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22368 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22369 argument, for consistency with GCPRO2_VAR, etc: it is now the
22370 prefix of the variable, not the variable itself. All uses
22372 * dired.c (directory_files_internal, file_name_completion):
22373 Rename locals to avoid shadowing.
22375 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22376 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22377 dired.c's scmp function, had undefined behavior.
22378 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22379 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22380 * buffer.h: ... to here, because these macros use current_buffer,
22381 and the new implementation with inline functions needs to have
22382 current_buffer in scope now, rather than later when the macros
22384 (downcase, upcase1): New static inline functions.
22385 (DOWNCASE, UPCASE1): Reimplement using these functions.
22386 This avoids undefined behavior in expressions like
22387 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22388 from race conditions in accessing the global variables
22389 case_temp1 and case_temp2.
22390 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22391 * lisp.h (case_temp1, case_temp2): Remove their decls.
22392 * character.h (ASCII_CHAR_P): Move from here ...
22393 * lisp.h: ... to here, so that the inline functions mentioned
22394 above can use them.
22396 * dired.c (directory_files_internal_unwind): Now static.
22398 * fileio.c (file_name_as_directory, directory_file_name):
22399 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22401 (file_name_as_directory): Use const pointers when appropriate.
22402 (Fexpand_file_name): Likewise. In particular, newdir might
22403 point at constant storage, so make it a const pointer.
22404 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22405 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22407 (Fset_file_times, Finsert_file_contents, auto_save_error):
22408 Rename locals to avoid shadowing.

22411 (Ftry_completion, Fall_completions): Rename or remove locals
22412 to avoid shadowing.
22414 * marker.c (bytepos_to_charpos): Remove; unused.
22416 * lisp.h (verify_bytepos, count_markers): New decls,
22417 so that gcc does not warn that these functions aren't declared.
22419 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22420 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22421 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22422 (copy_text): Remove unused local var.
22424 * filelock.c (within_one_second): Now static.
22425 (lock_file_1): Rename local to avoid shadowing.
22427 * buffer.c (fix_overlays_before): Mark locals as initialized.
22428 (fix_start_end_in_overlays): Likewise. This function should be
22429 simplified by using pointers-to-pointers, but that's a different
22431 (switch_to_buffer_1): Now static.
22432 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22433 (report_overlay_modification): Rename locals to avoid shadowing.
22435 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22436 Fix pointer signedness issue.
22437 (sys_subshell): Mark local as volatile if checking for lint,
22438 to suppress a gcc -Wclobbered warning that does not seem to be right.
22439 (MAXPATHLEN): Define only if needed.
22441 * process.c (serial_open, serial_configure): Move decls from here ...
22442 * systty.h: ... to here, so that they can be checked.
22444 * fns.c (get_random, seed_random): Move extern decls from here ...
22445 * lisp.h: ... to here, so that they can be checked.
22447 * sysdep.c (reset_io): Now static.
22448 (wait_for_termination_signal): Remove; unused.
22450 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22451 (copy_keymap_item, append_key, push_text_char_description):
22453 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22454 (DENSE_TABLE_SIZE): Remove; unused.
22455 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22456 (describe_map_tree):
22457 Rename locals to avoid shadowing.
22459 * keyboard.c: Declare functions static if they are not used elsewhere.
22460 (echo_char, echo_dash, cmd_error, top_level_2):
22461 (poll_for_input, handle_async_input): Now static.
22462 (read_char, kbd_buffer_get_event, make_lispy_position):
22463 (make_lispy_event, make_lispy_movement, apply_modifiers):
22464 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
22465 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
22466 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
22467 (read_key_sequence, read_char): Mark locals as initialized.

22477 (DEFINE_DUMMY_FUNCTION): New macro.
22478 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):

22481 if GCC considers string literals to be constants.
22483 * lisp.h (fatal_error_signal): Add decl, since it's exported.

22544 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22545 These macros can no longer be used for assignment.
22547 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

22603 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
22605 Improve quality of tests for time stamp overflow.
22606 For example, without this patch (encode-time 0 0 0 1 1
22607 1152921504606846976) returns the obviously-bogus value (-948597
22608 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22609 reports time overflow. See
22610 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
22611 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
