31 so simplify-away some unnecessary exactness.
32 (POINTER): Remove; all uses removed.
33 (data_space_start): Now char *, to avoid casts.
34 (exceeds_lisp_ptr): New function, replacing the old
35 EXCEEDS_LISP_PTR macro. All uses changed.

57 * ralloc.c (SIZE, POINTER, NIL):
58 * vm-limit.c (POINTER):
59 Remove, replacing all uses with C89 equivalents. These old
60 symbols were present only for porting to pre-C89 platforms.
62 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
64 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
65 This avoids warning messages reported as part of Bug#13546.
67 2013-02-21 Ken Brown <kbrown@cornell.edu>
69 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

78 (syms_of_keyboard): Adjust accordingly.
80 2013-02-19 Daniel Colascione <dancol@dancol.org>
82 * sheap.c (report_sheap_usage): Use message, not message1, so
83 that we don't try to create a buffer while we're in the middle
84 of dumping Emacs. Explain why.
86 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
87 * search.c (find_newline): Return byte position in bytepos.

182 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
184 Fix AIX port (Bug#13650).
185 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
186 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
187 was #undeffed earlier, so it cannot be used as a macro here.
188 Use the constant and not the macro.
190 2013-02-15 Eli Zaretskii <eliz@gnu.org>
192 * w32proc.c (new_child): If no vacant slots are found in

200 STATUS_READ_IN_PROGRESS. (Bug#13546)
202 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
204 * gtkutil.c (tb_size_cb): New function.

224 2013-02-13 Glenn Morris <rgm@gnu.org>
226 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
228 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
230 Improve AIX port some more (Bug#13650).
231 With this, it should be as good as it was in 23.3, though it's
232 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
233 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
234 * unexaix.c (start_of_text): Remove.
235 (_data, _text): Declare as char[], not int, as AIX manual suggests.
236 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
237 (orig_load_scnptr, orig_data_scnptr):
238 Now off_t, not long, since they are file offsets.
239 (make_hdr): Use _data, not start_of_data ().
240 This is the key part of the fix.
241 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
242 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
244 * pre-crt0.c (data_start): Initialize to 1.
245 This ports to compilers that optimize the external declaration
246 'int x = 0;' as if it were 'int x;' to shrink the executable.
248 Improve AIX port (Bug#13650).
249 This doesn't fix the bug, but it makes progress: Emacs builds now.
250 * unexaix.c: Include inttypes.h, stdarg.h.
251 (report_error, report_error_1): Mark as _Noreturn.
252 (report_error): Don't report the wrong errno.
253 (report_error_1): Now varargs. All callers changed.
254 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
255 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
256 (write_ptr): Use %p to print address rather than %lx and a cast
257 to unsigned long. Grow buffer a bit, to be safer.
259 2013-02-13 Eli Zaretskii <eliz@gnu.org>
261 * bidi.c (bidi_resolve_neutral): After finding the next
262 non-neutral character, accept NEUTRAL_ON type as well, because
263 directional control characters, such as LRE and RLE, have their
264 type converted to that by bidi_resolve_weak. This avoids aborts
265 when LRE/RLE follows a run of neutrals.
266 (bidi_move_to_visually_next): Assert that return value of
267 bidi_peek_at_next_level is non-negative. Negative values will
270 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
272 Minor getenv-related fixes.

278 Omit unnecessary cast of getenv or egetenv.
280 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
282 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
285 2013-02-12 Eli Zaretskii <eliz@gnu.org>
287 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
289 (display_line): Set w->region_showing to the value of
290 it->region_beg_charpos, not to -1. This fixes redisplay
291 optimization when cursor is moved up after M->. (Bug#13623)
293 (try_scrolling): Scroll text up more if point is too close to ZV
294 and inside the scroll margin. This makes sure point is moved
295 outside the scroll margin in these cases.
297 * window.h (struct window): region_showing can no longer be
300 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
302 Tune by using memchr and memrchr.
303 * doc.c (Fsnarf_documentation):
304 * fileio.c (Fsubstitute_in_file_name):
305 * search.c (find_newline, scan_newline):
306 * xdisp.c (pos_visible_p, display_count_lines):
307 Use memchr and memrchr rather than scanning byte-by-byte.
308 * search.c (find_newline): Rename from scan_buffer.
309 Omit first arg TARGET, as it's always '\n'. All callers changed.
311 Clean up read_key_sequence a tiny bit more.
312 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
313 (read_key_sequence): Remove unused locals.
315 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
317 Clean up read_key_sequence a bit; reread active keymaps after first event.
318 * keyboard.c (read_char, read_char_x_menu_prompt)
319 (read_char_minibuf_menu_prompt):
320 Replace nmaps+maps with a single `map' arg.
321 (follow_key): Operate on a single map.
322 (active_maps): New function.
323 (test_undefined): Also return true for nil bindings.
324 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
325 a single (composed) keymap. Remember `first_event' to choose the right
326 set of active keymaps. Recompute the set of keymaps after receiving
327 the first event. Remove GOBBLE_FIRST_EVENT.
328 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
329 * keyboard.h (read_char): Update declaration.
330 * lread.c (read_filtered_event): Adjust call to read_char.
332 2013-02-11 Eli Zaretskii <eliz@gnu.org>
334 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
335 Don't use the limitation on backwards movement when lines are truncated
336 in the window. (Bug#13675)
338 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
340 * marker.c (set_marker_internal): If desired position is passed
341 as a marker, avoid call to buf_charpos_to_bytepos.
342 * window.c (Fset_window_point): Omit redundant type checking.
343 (Fset_window_start): Likewise. Format comment.
344 (window_scroll_pixel_based): Use set_marker_restricted_both
345 with character and byte positions obtained from an iterator.
346 (Fset_window_configuration): Use set_marker_restricted_both.
347 * xdisp.c (message_dolog): Likewise.
349 2013-02-10 Eli Zaretskii <eliz@gnu.org>
351 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
352 When text lines are longer than window's screen lines, don't move back
353 too far. This speeds up some redisplay operations. (Bug#13675)
355 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
357 * syntax.c (scan_sexps_forward): Fix byte position calculation
358 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.

362 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
365 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
367 Minor hashing refactoring.
368 * fns.c (SXHASH_REDUCE): Move to lisp.h.
369 (sxhash_float): Return EMACS_UINT, for consistency with the other
371 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
372 non-static inline function and therefore can't use static vars.
373 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
374 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
375 with the other hash functions.
377 2013-02-09 Eli Zaretskii <eliz@gnu.org>
379 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
380 XXXXXX part of the temporary file pattern is not downcased even

469 2013-02-04 Eli Zaretskii <eliz@gnu.org>
471 * xdisp.c (window_buffer_changed): region_showing can be negative,
472 which still means region is being displayed.
473 (redisplay_internal): Resurrect code that forced redisplay of the
474 whole window when showing region and the mark has changed.
475 Record the new mark position to allow redisplay optimizations.
476 (display_line): If it->region_beg_charpos is non-zero, set the

479 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
480 not bitfield of 1 bit.
482 2013-02-03 Daniel Colascione <dancol@dancol.org>
484 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
485 daemon mode works on cygw32 when Emacs is installed and not just
488 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
490 Avoid file time stamp bug on MS-Windows (Bug#13149).
491 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
492 as FAT32 doesn't update time stamps when truncating them.
493 Also, check that a file time stamp is not a multiple of 100 ns;
494 this should catch all instances of the problem on MS-Windows,
495 as its native file system resolution is 100 ns or worse, and
496 checking for a non-multiple of 100 ns should impose only a small
497 overhead on systems with ns resolution.
499 2013-02-02 Eli Zaretskii <eliz@gnu.org>
501 Avoid encoding file names on MS-Windows when they need to be run
502 through dostounix_filename.
503 * w32.c (normalize_filename): Accept an additional argument
504 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
505 downcase it even if w32-downcase-file-names is non-nil.
506 (dostounix_filename): Accept an additional argument MULTIBYTE and
507 pass it to normalize_filename.
508 (emacs_root_dir): Adjust.
510 * msdos.h (dostounix_filename): Adjust prototype.
512 * w32.h (dostounix_filename): Adjust prototype.
514 * msdos.c (dostounix_filename): Accept an additional argument and
516 (init_environment): Adjust callers of dostounix_filename.
518 * fileio.c (Ffile_name_directory, file_name_as_directory)
519 (directory_file_name, Fexpand_file_name)
520 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
522 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
524 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
525 variables, as egetenv is case-insensitive for DOS_NT.
527 * dired.c (file_name_completion): Don't call Fdirectory_file_name
528 with an encoded file name.
530 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
531 Adjust calls to dostounix_filename.
533 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
535 * unexw32.c (unexec): Adjust call to dostounix_filename.
537 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
539 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
542 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
545 * callproc.c (Fcall_process): Make sure program name in PATH and
546 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
547 is passed to exec/spawnve, which fails unless the file-name
550 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
551 even if w32-quote-process-args is nil.
553 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
555 Fix timestamp bug when write-region appends nothing (Bug#13149).
556 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
557 the file's time stamp doesn't change if Emacs happens to write nothing
558 to the file, and on a buggy file system this could cause Emacs to
559 incorrectly infer that the file system doesn't have the bug.
560 Avoid this problem by inhibiting the inference in this case.
562 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
564 * window.h (struct window): Convert base_line_number, base_line_pos
565 and column_number_displayed members from Lisp_Object to ptrdiff_t.
566 Convert region_showing member from Lisp_Object to bitfield.
567 Remove sequence_number member. Adjust comments.
568 * window.c (sequence_number): Remove.
569 (make_window): Initialize column_number_displayed.
570 * print.c (print_object): Follow the printed representation of
571 frames and print window pointer to distinguish between windows.
572 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
573 * xdisp.c (wset_base_line_number, wset_base_line_pos)
574 (wset_column_number_displayed, wset_region_showing): Remove.
575 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
576 (try_scrolling, try_cursor_movement, redisplay_window)
577 (try_window_reusing_current_matrix, try_window_id, display_line)
578 (display_mode_lines, decode_mode_spec): Adjust users.
579 * .gdbinit (pwinx): Do not print sequence_number.
581 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
583 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
584 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
585 * dired.c: Include <fcntl.h>.
586 (open_directory): New function, which uses open and fdopendir
587 rather than opendir. DOS_NT platforms still use opendir, though.
588 (directory_files_internal, file_name_completion): Use it.
589 (file_attributes): New function, with most of the old Ffile_attributes.
590 (directory_files_internal, Ffile_attributes): Use it.
591 (file_attributes, file_name_completion_stat): First arg is now fd,
592 not dir name. All uses changed. Use fstatat rather than lstat +
594 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
595 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
596 (emacs_readlinkat): New function, with much of the old
597 Ffile_symlink_p, but with an fd argument for speed.
598 It uses readlinkat rather than careadlinkatcwd, so that it
599 need not assume the working directory.
600 (Ffile_symlink_p): Use it.
601 * filelock.c (current_lock_owner): Use emacs_readlinkat
602 rather than emacs_readlink.
603 * lisp.h (emacs_readlinkat): New decl.
604 (READLINK_BUFSIZE, emacs_readlink): Remove.
605 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
606 (emacs_norealloc_allocator, emacs_readlink): Remove.
607 This stuff is moved to fileio.c.
608 * w32.c (fstatat, readlinkat): New functions.
609 (careadlinkat): Don't check that fd == AT_FDCWD.
610 (careadlinkatcwd): Remove; no longer needed.
612 2013-01-31 Glenn Morris <rgm@gnu.org>
614 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
615 (Fwrite_region): Update for new choose_write_coding_system args.
616 Move the last piece of choose_write_coding_system here. (Bug#13522)
617 (syms_of_fileio): Add choose-write-coding-system.
619 2013-01-30 Eli Zaretskii <eliz@gnu.org>
621 * w32.c (sys_open): Zero out the flags for the new file descriptor.
622 (sys_close): Zero out the flags for the file descriptor before
623 closing it. (Bug#13546)
625 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
626 (logon_network_drive, stat_worker, symlink, chase_symlinks):
627 Use CharNextExA and CharPrevExA to iterate over file names encoded in
630 * w32.c (w32_get_long_filename, init_environment, readlink):
631 Support file names encoded in DBCS codepages.
632 (readlink): Use the current file-name-coding-system, not the ANSI
633 codepage, to decode and handle targets of symlinks.
635 2013-01-28 Eli Zaretskii <eliz@gnu.org>
637 * w32.c (opendir): Now accepts a 'const char *'.
639 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
641 Remove obsolete redisplay code. See the discussion at
642 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
643 * dispnew.c (preemption_period, preemption_next_check): Remove.
644 (Vredisplay_preemption_period): Likewise.
645 (update_frame, update_single_window, update_window, update_frame_1):
646 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
647 used, following the 2012-06-22 change.
649 2013-01-25 Eli Zaretskii <eliz@gnu.org>
651 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
653 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
655 * font.c (num_fonts): Remove the leftover from old
656 debugging code. Adjust comment style here and there.
657 * insdel.c (insert_1): Remove.
658 * lisp.h (insert_1): Remove prototype.
659 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
661 2013-01-25 Eli Zaretskii <eliz@gnu.org>
663 * w32.c (max_filename_mbslen): New function.
664 (normalize_filename, readdir): Use it to detect locales where ANSI
665 encoding of file names uses a double-byte character set (DBCS).
666 If a DBCS encoding is used, advance by characters using
667 CharNextExA, instead of incrementing a 'char *' pointer.
668 Use _mbslwr instead of _strlwr. (Bug#13515)
670 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
671 request of memory reservation to 1.7GB. (Bug#13065)
673 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
675 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
676 at check_extra_latin label. (Bug#13505)
678 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
680 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
681 Avoid redundant calls to strlen.
683 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
685 Drop async_visible and async_iconified fields of struct frame.
686 This is possible because async input is gone; for details, see
687 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
688 * frame.h (struct frame): Remove async_visible and async_iconified
689 members, convert garbaged to unsigned bitfield. Adjust comments.
690 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
691 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
692 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
693 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
694 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
696 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
697 properly. Likewise for obscured.
699 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
702 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
704 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
706 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
707 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
709 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
711 * xdisp.c (message2, message2_nolog): Remove functions.
712 (message3, message3_nolog): Extract nbytes and multibyteness directly
713 from the string. Change all callers.
714 (message3_nolog): Don't set message_enable_multibyte since set_message
715 will reset it anyway.
716 (message1, message1_nolog): Use message3.
717 (vmessage): Use a stack allocated buffer rather than f->message_buf.
718 (with_echo_area_buffer): Remove last two arguments. Update all callers.
719 (set_message): Drop all but the second arg, which has to be a string.
720 (set_message_1): Simplify now that we know that a1 is NULL and the
721 second arg is a string.
722 * frame.h (struct frame): Remove `message_buf' field.
723 Use glyphs_initialized_p instead.
724 (FRAME_MESSAGE_BUF): Remove macro.
725 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
726 * lisp.h (message2, message2_nolog): Remove declarations.
727 (message3, message3_nolog): Update declarations.
728 * keyboard.c (read_char_minibuf_menu_text)
729 (read_char_minibuf_menu_width): Remove vars.
730 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
731 to correctly handle multibyte strings.
732 * frame.c (delete_frame): Don't free message_buf any more.
733 * editfns.c (message_text, message_length): Remove vars.
734 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
735 * fileio.c (auto_save_error): Use message3 instead of message2.
736 * dispnew.c (adjust_frame_message_buffer): Remove function.
738 2013-01-23 Eli Zaretskii <eliz@gnu.org>
740 * w32term.c (w32fullscreen_hook): Account correctly for the screen
741 real estate used for the tool bar and the menu bar.
743 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
745 * insdel.c (prepare_to_modify_buffer): Force redisplay if
746 hidden buffer is prepared to modification (Bug#13164).
748 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
750 * window.h (struct window): Change window_end_valid member from
751 Lisp_Object to a bitfield. Adjust comments.
752 (wset_window_end_valid): Remove.
753 * window.c (adjust_window_count): Clear window_end_valid.
754 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
755 (Fwindow_line_height, set_window_buffer, Frecenter)
756 (Fsplit_window_internal, Fdelete_other_windows_internal)
757 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
758 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
759 * xdisp.c (check_window_end, reconsider_clip_changes)
760 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
761 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
762 (find_first_unchanged_at_end_row, try_window_id): Likewise.
764 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
766 * xdisp.c (mark_window_display_accurate): Simplify the loop
767 assuming that the only one of vchild, hchild or buffer window
768 slots is non-nil. Call mark_window_display_accurate_1 for
769 the leaf windows only.
770 (mark_window_display_accurate_1): Always assume leaf window.
773 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
775 * emacs.c (Qkill_emacs_hook): Now static.
777 * fileio.c (Finsert_file_contents): Simplify.
778 Remove unnecessary assignments and tests.
780 2013-01-21 Eli Zaretskii <eliz@gnu.org>
782 * w32.c (acl_set_file): Don't test for errors unless
783 set_file_security returns FALSE. Avoids spurious errors when
786 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
788 * fileio.c (Finsert_file_contents): Revert code introduced at
789 2013-01-18 in favor of the simpler and generally better fix.
790 Save stack space by removing 'buffer' and reusing 'read_buf'
793 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
795 * lisp.h (eabs): Define unconditionally (Bug#13419).
796 The old "#if !defined (eabs)" was an unnecessary revenant of back
797 when this macro was called "abs". Document 'eabs' better.
799 2013-01-19 Glenn Morris <rgm@gnu.org>
801 * fns.c (Frandom): Doc fix.
803 2013-01-19 Eli Zaretskii <eliz@gnu.org>
805 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
806 segfault when there are lots of overlays.
808 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
809 when there are lots of overlays.
810 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
811 for the details and a way to reproduce.
813 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
815 * fileio.c: Use O_APPEND to append.
816 This corresponds better to the natural interpretation of "append",
817 and avoids the need to open the output file twice, or to invoke
818 lseek when APPEND is neither nil nor a number.
819 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
820 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
821 file possibly twice, and lseeking to its end; this avoids the
822 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
823 at the same time: the combination is never needed and apparently
824 it doesn't work with DOS_NT.
826 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
827 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
829 Allow floating-point file offsets.
830 Problem reported by Vitalie Spinu in
831 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
832 * fileio.c (emacs_lseek): Remove.
833 (file_offset): New function.
834 (Finsert_file_contents, Fwrite_region): Use it.
836 2013-01-19 Chong Yidong <cyd@gnu.org>
838 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
839 aborting on Fsignal (Bug#13289).
841 2013-01-19 Eli Zaretskii <eliz@gnu.org>
843 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
844 set_file_security as failure due to insufficient privileges.
845 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
846 (fstat): Return owner and group like 'stat' and 'lstat' do.
848 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
850 Work around bug in CIFS and vboxsf file systems (Bug#13149).
851 The bug was observed on Ubuntu operating inside a virtual machine,
852 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
853 The workaround introduces a race condition on non-buggy hosts,
854 but it's an unlikely race and anyway there's a nearly identical
855 nearby race that can't be fixed.
856 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
858 (Fwrite_region): Test for file system time stamp bug.
859 (init_fileio): New function.
860 * lisp.h (init_fileio): Declare it.
861 * emacs.c (main): Call it.
863 * fileio.c (Finsert_file_contents): Simplify new diagnostic
864 and make it more consistent with other stat-failure diagnostics.
866 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
868 Fix crash when inserting data from non-regular files.
869 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
870 for the error description produced by valgrind.
871 * fileio.c (read_non_regular): Rename to read_contents.
872 Free Lisp_Save_Value object used to pass parameters.
873 (read_non_regular_quit): Rename to read_contents_quit.
874 (Finsert_file_contents): Redesign internal file reading loop to adjust
875 gap and end positions after each read and so help make_gap to work
876 properly. Do not signal an I/O error too early and so do not leave
877 not yet decoded characters in a buffer, which was the reason of
878 redisplay crash. Use list2 to build return value. Adjust comments.
880 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
882 Close a race when statting and reading files (Bug#13149).
883 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
884 This avoids a race if the file is renamed between stat and open.
885 This race is not the problem originally noted in Bug#13149;
886 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
888 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
890 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
891 objects, related functions and macros.
892 (make_save_value): Adjust prototype.
893 (make_save_pointer): New prototype.
894 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
895 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
896 * alloc.c (format_save_value): Rename to make_save_value.
897 (make_save_pointer): New function.
898 (record_xmalloc): Use make_save_pointer.
899 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
900 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
901 Change users of make_save_value to make_save_pointer.
902 Likewise for format_save_value and make_save_value.
904 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
906 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
907 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
908 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
911 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
913 * alloc.c (free_save_value): Now static.
915 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
917 * keymap.c (map_keymap_internal): Use format_save_value.
918 (map_keymap_char_table_item): Adjust accordingly.
919 * fileio.c (non_regular_fd, non_regular_inserted)
920 (non_regular_nbytes): Remove.
921 (Finsert_file_contents): Convert trytry to ptrdiff_t.
922 Use format_save_value to pass parameters to read_non_regular.
923 (read_non_regular): Use XSAVE_ macros to extract parameters.
925 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
927 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
929 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
931 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
932 extraction from any Lisp_Save_Value slot. Add type checking.
933 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
934 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
935 * xselect.c: All users changed.
937 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
939 Some convenient bits to deal with Lisp_Save_Values.
940 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
941 (allocate_misc): Remove prototype.
942 (format_save_value): New prototype.
943 * alloc.c (allocate_misc): Revert back to static.

985 * editfns.c (save_excursion_save): Pack everything within
986 Lisp_Save_Value and so avoid xmalloc.
987 (save_excursion_restore): Adjust to match new layout. Use free_misc
988 because we do not allocate extra memory any more. Add eassert.
989 * print.c (print_object): New code to print Lisp_Save_Value. Do not
990 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
991 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
992 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

1002 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1004 Fix SIGDANGER handlers, for AIX (Bug#13408).
1005 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1008 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1010 * xterm.c (syms_of_xterm): Adjust documentation for

1058 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1060 Avoid unnecessary byte position calculation for the gap movement.
1061 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1072 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1074 * term.c (init_tty): Use them instead of rolling our own code.
1075 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1076 switches from 'signal' to 'pthread_sigmask', which is safer in
1077 multithreaded applications.
1078 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1079 which has already arranged for that.
1080 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1081 This is the main part of the bug fix.

1093 predicate, which is how it's really used now. Adjust comment.
1094 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1095 * buffer.c (buffer_slot_type_mismatch): Remove.
1096 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1097 predicate. Adjust comment.

1100 left-margin-width, right-margin-width, left-fringe-width,
1101 right-fringe-width, scroll-bar-width and buffer-display-count.
1102 Use Qstringp for default-directory, buffer-file-name,
1103 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1104 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1106 * data.c (store_symval_forwarding): Adjust to call the predicate.

1123 (make_gap_1): New function to adjust the gap of any buffer.
1124 * coding.c (coding_alloc_by_making_gap): Use it.
1125 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1149 trailing dash is properly added.
1151 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1153 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1154 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1155 digits for buffer positions, before misalignment starts.
1156 Display "0" for integer "object" field.
1157 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1158 Display the newline glyph more unambiguously.
1160 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1162 * nsterm.m (ns_draw_underwave):
1163 * w32term.c (w32_draw_underwave):
1164 * xterm.c (x_draw_underwave): Make underwave look more triangular
1165 and also degrade gracefully for small fonts. (Bug#13000)
1167 * nsterm.m (ns_draw_text_decoration):
1168 * w32term.c (x_draw_glyph_string):
1169 * xterm.c (x_draw_glyph_string): Don't use previous underline
1170 thickness and position if previous underline type is underwave.
1172 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1174 * fileio.c (Ffile_acl): Undocument return format.
1176 2013-01-02 Glenn Morris <rgm@gnu.org>

1190 * term.c (tty_ins_del_lines):
1191 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1192 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1194 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1196 * w32.c (unsetenv): Set up the string passed to _putenv
1198 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1199 for the bug this caused.
1201 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1203 * coding.c (Qmac): Now static.
1205 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1207 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1208 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1215 by TOOLBAR_TOP_WIDGET.
1216 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1217 Check toolbar_is_packed.
1218 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1219 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1220 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1222 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1223 (xg_update_menubar): Update title only if
1224 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1225 (xg_update_submenu): Skip tearoff only if
1226 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1227 (xg_initialize): Initialize xg_detached_menus only if
1228 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1230 * xterm.h (struct x_output): Surround handlebox_widget with
1231 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1232 toolbar_in_hbox is bool.
1234 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1236 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1237 (LIBS_GNUSTEP): Define.
1238 (LIBES): Add $(LIBS_GNUSTEP).
1239 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1241 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1243 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1244 continuation glyph on a TTY with an indication of an empty line.
1247 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1249 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1250 file's SELinux context or ACLs successfully set, nil otherwise.
1252 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1254 * w32proc.c (reader_thread): Avoid passing NULL handles to
1255 SetEvent and WaitForSingleObject.
1257 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1259 Port EXTERNALLY_VISIBLE to Clang 3.2.
1260 * conf_post.h (__has_attribute): New macro.
1261 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1263 2012-12-27 Glenn Morris <rgm@gnu.org>
1265 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1266 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1268 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1270 * fileio.c (file_name_as_directory, directory_file_name):
1271 Accept an additional argument MULTIBYTE to indicate whether the input C
1272 came from a multibyte or a unibyte Lisp string; all callers
1273 adjusted. Don't assume the input string is always multibyte.
1275 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1276 don't ENCODE_FILE them, and return a unibyte string if the input
1278 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1279 don't assume the input strings will always be multibyte. If the
1280 input strings are multibyte, decode strings obtained from C
1283 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1285 * lisp.h (toplevel): Add two notices to the comment about
1286 defining a new Lisp data type.

1290 * alloc.c (valid_lisp_object_p): Adjust comment.
1292 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1294 * keyboard.c (record_asynch_buffer_change): Initialize an event
1295 only if it's really needed.
1296 * frame.h (enum output_method): Remove output_mac member since
1297 it's a leftover from the deleted code.
1298 * frame.c (Fframep): Adjust user here ...
1299 * terminal.c (Fterminal_live_p): ... and here.
1300 * coding.c (Qmac): Now here because it's only used to denote
1301 end-of-line encoding type.
1302 (syms_of_coding): DEFSYM it.
1303 * frame.h (Qmac): Remove duplicated declaration.
1305 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1307 * window.c (select_window_1): Now static, since it's used only here.
1309 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1311 * window.c (window_body_cols): Subtract display margins from the
1312 window body width on TTYs as well. See
1313 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1314 for the original report.
1316 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1318 * xdisp.c (redisplay_window): Remove inner local variable
1319 because the outer shadowed one has the same meaning.
1320 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1322 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1323 (xg_create_tool_bar): Adjust users.
1325 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1327 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1328 * buffer.c (Fget_buffer_create): Use it to set compact field of
1329 struct buffer_text to avoid accessing an uninitialized value
1330 when compact_buffer is called for the first time.
1331 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1332 (Fset_buffer_modified_p): Use buffer_window_count to check
1333 whether the buffer is displayed in some window.
1334 * xdisp.c (message_dolog): Likewise.
1336 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1338 * w32.c (acl_set_file): If setting the file security descriptor
1339 fails, and the new DACL is identical to the existing one, silently
1340 return success. This fixes problems for users backing up their
1341 own files without having the necessary privileges for setting
1342 security descriptors.
1344 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1346 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1347 after WaitForSingleObject returns normally. This expedites reader
1348 thread shutdown when delete_child triggers it.
1349 (reap_subprocess): More accurate commentary for why we call
1350 delete_child only when cp->fd is negative.
1352 * w32.c (sys_close): Do not call delete_child on a subprocess
1353 whose handle is not yet closed. Instead, set its file descriptor
1354 to a negative value, so that reap_subprocess will call
1355 delete_child on that subprocess when its SIGCHLD arrives.
1356 This avoids closing handles used for communications between sys_select
1357 and reader_thread, which doesn't give sys_select a chance to
1358 notice that the process exited and invoke the SIGCHLD handler for
1361 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1363 * nsfns.m (Fns_do_applescript): Run event loop until script has
1364 been executed (Bug#12969).
1365 (ns_run_ascript): Chech as_script for nil, set to nil after
1368 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1370 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1372 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1374 * w32term.c (w32fullscreen_hook): New function.
1375 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1377 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1379 * fileio.c (Finsert_file_contents): Doc fix.
1381 * w32proc.c (new_child, delete_child, find_child_pid): For a
1382 subprocess, consider its slot being in use as long as its process
1383 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1384 slot when a new process is started immediately after killing
1385 another one, without waiting enough time for the first process to
1386 be reaped and resources allocated for it be orderly freed.
1388 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1390 2012-12-21 Chong Yidong <cyd@gnu.org>
1392 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1394 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1396 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1398 * w32.c (get_name_and_id): Always pass NULL as the first argument
1399 of lookup_account_sid. Avoids crashes with UNC file names that
1400 refer to DFS domains, not to specific machine names. (Bug#12621)
1401 Remove now unused argument FNAME; all callers changed.
1402 (get_file_owner_and_group): Remove now unused argument FNAME; all
1405 2012-12-21 Chong Yidong <cyd@gnu.org>
1407 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1408 error for invalid chars, don't check for a nil return value.
1410 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1412 Avoid calls to CHAR_TO_BYTE if byte position is known.
1413 * editfns.c (make_buffer_string_both): Use move_gap_both.
1414 (Fbuffer_string): Use make_buffer_string_both.
1415 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1417 (buf_bytepos_to_charpos): Likewise.

1496 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1498 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1499 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1500 for some of that bug's symptoms can now cause Emacs to abort.
1501 Remove the workaround.
1502 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1503 The bug that caused SIGCHLD to get lost has been fixed, and the

1551 asynchronous subprocess, record the name of the input file name,
1553 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1554 delete the file, record it as pending deletion when the subprocess

1582 'lstat', which don't need that information, much faster.
1584 * dired.c (Ffile_attributes) [WINDOWSNT]:
1585 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1586 owner and group information from 'lstat'.
1588 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1590 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1591 as that confuses set-auto-coding, so insist on the head-read

1620 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1622 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1623 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1624 Remove unnecessary S_ISLNK test, as (contra the comments) this
1625 function can't copy symlinks. Improve quality of error message
1626 when attempting to copy files that are neither regular files nor

1645 * inotify.c (inotify_callback): Generate an Emacs event for every
1646 incoming inotify event.
1648 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1650 * xdisp.c (handle_face_prop): Fix logic of computing
1651 it->start_of_box_run_p.

1655 iterator's start_of_box_run_p flag before prepending the stretch.

1658 left_box_line_p and right_box_line_p flags of the glyph for R2L
1659 glyph rows. (Bug#13011)

1897 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1898 Remove USG and vlimit methods; no longer used these days.
1899 Add #error catchall just in case.
1901 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1902 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1903 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1904 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1905 (deleted_pid_list, Fdelete_process, create_process)
1906 (record_child_status_change, handle_child_signal, deliver_child_signal)
1907 (init_process_emacs, syms_of_process):
1908 Assume SIGCHLD is defined.
1909 (parse_signal): Remove. All uses removed.
1910 (abbr_to_signal): New static function.
1911 (Fsignal_process): Use it to convert signal names to ints.
1912 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1913 kill (getpgrp (), ...).
1914 (emacs_sigaction_init): Assume SIGCHLD is defined.
1915 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1916 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1917 * syssignal.h (EMACS_KILLPG): Remove.
1918 All uses replaced by 'kill' with a negative pid.
1919 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1920 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1922 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1924 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1925 This will cause a production Emacs to dump core instead of
1928 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1930 * frame.c (make_frame): Do not set window's buffer to t.
1931 * window.c (Fsplit_window_internal): Likewise. Previously it was
1932 used to indicate that the window is being set up. Now we use
1933 set_window_buffer for all new windows, so the condition in ...
1934 (Fset_window_buffer): ... is always true and can be removed.
1936 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1938 Convenient macro to check whether the buffer is hidden.
1939 * buffer.h (BUFFER_HIDDEN_P): New macro.
1940 * frame.c (make_frame): Use it. Adjust comment.
1941 * buffer.c (candidate_buffer): New function.
1942 (Fother_buffer, other_buffer_safely): Use it.
1944 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1946 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1947 if the child process is still running. Instead, exit the wait
1948 loop and return zero. (Bug#13086)
1950 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1952 * frame.h (x_char_width, x_char_height): Remove prototypes.
1953 * w32term.h (x_char_width, x_char_height): Likewise.
1954 * xfns.c (x_char_width, x_char_height): Remove.
1955 * w32fns.c (x_char_width, x_char_height): Likewise.
1956 * nsfns.c (x_char_width, x_char_height): Likewise.
1957 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
1959 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
1960 * keyboard.c (command_loop_1): Remove prototype.

1963 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1965 Fix a recently-introduced delete-process race condition.
1966 * callproc.c, process.h (record_kill_process):
1967 New function, containing part of the old call_process_kill.
1968 (call_process_kill): Use it.
1969 This does not change call_process_kill's behavior.
1970 * process.c (Fdelete_process): Use record_kill_process to fix a
1971 race condition that could cause Emacs to lose track of a child.
1973 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1975 Avoid code duplication between prev_frame and next_frame.
1976 * frame.c (candidate_frame): New function. Add comment.
1977 (prev_frame, next_frame): Use it. Adjust comment.
1979 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1981 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1982 fails, signal an error instead of continuing with an empty
1984 Encode expanded temp file pattern before passing it to mkstemp or
1987 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1988 Encode the file name before passing it to dostounix_filename, in
1989 case it will downcase it (under w32-downcase-file-names).
1992 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1994 Minor call-process cleanups.
1995 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1996 at the same time as other platforms, to simplify analysis.
1997 No need for fd0_volatile since we have synch_process_fd.
1998 Avoid needless emacs_close; arg is always negative.
2000 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2002 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2005 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2007 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2008 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2009 and mouse_face_hidden members to a bitfields.
2010 * frame.h (struct frame): Remove set-but-not-used space_width member.
2011 (FRAME_SPACE_WIDTH): Remove.
2012 * nsterm.m, w32term.c, xterm.c: Adjust users.
2013 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2014 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2015 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2016 members to a bitfields.
2018 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2020 Don't let call-process be a zombie factory (Bug#12980).
2021 Fixing this bug required some cleanup of the signal-handling code.
2022 As a side effect, this change also fixes a longstanding rare race
2023 condition whereby Emacs could mistakenly kill unrelated processes,
2024 and it fixes a bug where a second C-g does not kill a recalcitrant
2025 synchronous process in GNU/Linux and similar platforms.
2026 The patch should also fix the last vestiges of Bug#9488,
2027 a bug which has mostly been fixed on the trunk by other changes.
2028 * callproc.c, process.h (synch_process_alive, synch_process_death)
2029 (synch_process_termsig, sync_process_retcode):
2030 Remove. All uses removed, to simplify analysis and so that
2031 less consing is done inside critical sections.
2032 * callproc.c (call_process_exited): Remove. All uses replaced
2033 with !synch_process_pid.
2034 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2035 These take the role of what used to be in unwind-protect arg.
2037 (block_child_signal, unblock_child_signal):
2038 New functions, to avoid races that could kill innocent-victim processes.
2039 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2040 (call_process_kill): Record killed processes as deleted, so that
2041 zombies do not clutter up the system. Do this inside a critical
2042 section, to avoid a race that would allow the clutter.
2043 (call_process_cleanup): Fix code so that the second C-g works again
2044 on common platforms such as GNU/Linux.
2045 (Fcall_process): Create the child process in a critical section,
2046 to fix a race condition. If creating an asynchronous process,
2047 record it as deleted so that zombies do not clutter up the system.
2048 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2049 light of these changes. Omit unnecessary call to emacs_close
2050 before failure, as the unwind-protect code does that.
2051 * callproc.c (call_process_cleanup):
2052 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2053 * process.c (record_deleted_pid): New function, containing
2054 code refactored out of Fdelete_process.
2055 (Fdelete_process): Use it.
2056 (process_status_retrieved): Remove. All callers changed to use
2057 child_status_change.
2058 (record_child_status_change): Remove, folding its contents into ...
2059 (handle_child_signal): ... this signal handler. Now, this
2060 function is purely a handler for SIGCHLD, and is not called after
2061 a synchronous waitpid returns; the synchronous code is moved to
2062 wait_for_termination. There is no need to worry about reaping
2063 more than one child now.
2064 * sysdep.c (get_child_status, child_status_changed): New functions.
2065 (wait_for_termination): Now takes int * status and bool
2066 interruptible arguments, too. Do not record child status change;
2067 that's now the caller's responsibility. All callers changed.
2068 Reimplement in terms of get_child_status.
2069 (wait_for_termination_1, interruptible_wait_for_termination):
2070 Remove. All callers changed to use wait_for_termination.
2071 * syswait.h: Include <stdbool.h>, for bool.
2072 (record_child_status_change, interruptible_wait_for_termination):
2074 (record_deleted_pid, child_status_changed): New decls.
2075 (wait_for_termination): Adjust to API changes noted above.
2077 * bytecode.c, lisp.h (Qbytecode): Remove.
2078 No longer needed after 2012-11-20 interactive-p changes.
2080 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2082 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2083 the scroll margin, move point outside the margin. (Bug#13055)
2085 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2087 * gtkutil.c (my_log_handler): New function.
2088 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2090 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2092 * lisp.h (modify_region): Rename to...
2093 (modify_region_1): ...new prototype.
2094 * textprop.c (modify_region): Now static. Adjust users.
2095 * insdel.c (modify_region): Rename to...
2096 (modify_region_1): ...new function to work with current buffer.
2097 Adjust comment and users. Use true and false for booleans.
2099 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2101 * alloc.c (free_save_value): New function.
2102 (safe_alloca_unwind): Use it.
2103 * lisp.h (free_save_value): New prototype.
2104 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2106 (save_excursion_restore): Adjust to match saved data structure.
2107 Use free_save_value to offload some work from GC. Drop obsolete
2110 2012-12-03 Chong Yidong <cyd@gnu.org>
2112 * fileio.c (Vauto_save_list_file_name): Doc fix.
2114 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2116 * w32fns.c: Remove prototype of atof.
2117 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2119 (file_dialog_callback): Make it UINT_PTR.
2121 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2124 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2125 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2128 2012-12-03 Glenn Morris <rgm@gnu.org>
2130 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2132 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2134 Fix xpalloc confusion after memory is exhausted.
2135 * alloc.c (xpalloc): Comment fix.
2136 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2137 and signals an error, do not clear charset_table_size, as
2138 charset_table is still valid.
2139 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2141 Use execve to avoid need to munge environ (Bug#13054).
2142 * callproc.c (Fcall_process):
2143 * process.c (create_process):
2144 Don't save and restore environ; no longer needed.
2145 * callproc.c (child_setup):
2146 Use execve, not execvp, to preserve environ.
2148 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2150 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2152 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2154 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2155 display for sliced images (Bug#10500).
2157 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2159 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2161 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2162 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2164 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2166 * xdisp.c (window_outdated): Remove eassert since it hits
2167 some suspicious corner cases (see Bug#13007 and Bug#13012).
2168 (mode_line_update_needed): New function.
2169 (redisplay_internal, redisplay_window): Use it.
2170 (ensure_selected_frame): New function.
2171 (redisplay_internal, unwind_redisplay): Use it.
2172 (redisplay_internal): Move comment about buffer_shared...
2173 (buffer_shared_and_changed): ...near to its real use.
2175 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2177 * callproc.c (Fcall_process): Don't misreport vfork failure.
2179 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2181 * callproc.c (Fcall_process): Fix vfork portability problems.
2182 Do not assume that fd[0], count, filefd, and save_environ survive
2183 vfork. Fix bug whereby wrong errno value could be reported for
2184 pipe failure. Some minor cleanups, too, as follows. Move buf and
2185 bufsize to the context where they're needed. Change new_argv to
2186 be of type char **, as this is more convenient and avoids casts.
2187 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2188 Now local constants, not macros.
2190 2012-11-18 Kenichi Handa <handa@gnu.org>
2192 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2193 for the variable "f".
2195 2012-11-13 Kenichi Handa <handa@gnu.org>
2197 * font.c (font_unparse_xlfd): Exclude special characters from the
2198 generating XLFD name.
2200 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2202 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

2223 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2224 highlighting on the frame was cleared. Prevents assertion
2225 violations when repeatedly clicking on the "Top" link of the
2226 "bread-crumbs" in Info buffers.

2235 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2236 were always defined.
2238 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2240 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2241 between bpos_covered and bpos_max. This fixes cursor display when
2242 several display strings follow each other.
2244 * .gdbinit (pgx): If the glyph's object is a string, display the
2245 pointer to string data, rather than the value of the string object
2246 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2248 * indent.c (Fvertical_motion): If the starting position is covered
2249 by a display string, return to one position before that, to avoid
2250 overshooting it inside move_it_to. (Bug#12930)
2252 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2254 * frame.h (struct frame): Remove display_preempted member

2261 (struct w32_output): Use bitfields for explicit_parent,
2262 asked_for_visible and menubar_active members.
2263 Drop unused pending_menu_activation member.
2264 * xterm.h (struct x_output): Drop outdated #if 0 code.
2265 Use bitfields for explicit_parent, asked_for_visible,
2266 has_been_visible and net_wm_state_hidden_seen members.

2270 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2271 of a literal "/". (Bug#12955)
2272 (gl-stamp): Invoke fc.exe directly, not through cmd.
2274 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

2277 * dired.c: Assume HAVE_DIRENT_H.
2278 (NAMLEN): Remove, replacing with ...
2279 (dirent_namelen): New function. All uses changed. Use the GNU macro
2280 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2281 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2282 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2283 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2285 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2286 * ndir.h: Rename to ../nt/inc/dirent.h.
2287 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2288 Do not include <dirent.h>; no longer needed.
2289 * w32.c: Include <dirent.h> rather than "ndir.h".
2291 2012-11-23 Chong Yidong <cyd@gnu.org>
2293 * xftfont.c (xftfont_open): Remove duplicate assignment.
2295 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2297 * alloc.c (Fgarbage_collect): Unblock input after clearing
2298 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2299 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2300 * msdos.c (IT_frame_up_to_date): Use it here...
2301 * w32term.c (w32_frame_up_to_date): ...here...
2302 * xterm.c (XTframe_up_to_date): ...and here...
2303 * nsterm.m (ns_frame_up_to_date): ...but not here.
2304 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2306 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2307 Do not check whether GC is in progress.
2309 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2311 * xdisp.c (window_buffer_changed): New function.
2312 (update_menu_bar, update_tool_bar): Use it to
2313 simplify large 'if' statements.
2314 (redisplay_internal): Generalize commonly used
2315 'tail' and 'frame' local variables.
2317 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2319 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2320 with Windows system header.
2322 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2324 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

2341 * emacs.c (main): Set the G_SLICE environment variable for all
2342 Cygwin builds, not just GTK builds. See
2343 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2345 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2347 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2348 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2349 Define for the MSVC compiler.
2351 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2353 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2354 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2355 dostounix_filename. Prevents crashes down the road, because
2356 dostounix_filename assumes it gets a unibyte string.
2357 Reported by Michel de Ruiter <michel@sentient.nl>, see

2364 * lread.c (init_obarray): Set `function' fields to Qnil.
2365 * eval.c (Fcommandp): Ignore Qunbound.
2366 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2367 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2368 Test NILP rather than Qunbound.
2369 (Ffmakunbound): Set to Qnil.
2370 (Fsymbol_function): Never signal an error.
2371 (Finteractive_form): Ignore Qunbound.
2373 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2375 * eval.c (interactive_p): Remove no-longer-used decl.
2377 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2379 * xdisp.c (buffer_shared): Adjust comment.
2380 (buffer_shared_and_changed): New function.
2381 (prepare_menu_bars, redisplay_internal): Use it to
2382 decide whether all windows or frames should be updated.
2383 (window_outdated): New function.
2384 (text_outside_line_unchanged_p, redisplay_window): Use it.
2385 (redisplay_internal): Likewise. Fix indentation.
2387 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2389 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2390 (syms_of_eval): Remove corresponding defsubr.
2391 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2393 2012-11-19 Daniel Colascione <dancol@dancol.org>
2395 * w32fns.c (Fx_file_dialog):
2396 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2397 cygwin_convert_file_name*.
2399 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2400 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2402 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2404 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2406 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2408 * w32select.c: Include w32common.h before w32term.h, so that
2409 windows.h gets included before w32term.h uses some of its
2410 features, see below.
2412 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2414 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2416 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2418 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2420 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2421 (ns_select): Return at once if events are held (Bug#12834).
2423 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2425 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2426 Needed following 2012-10-20 change. (Bug#12902)
2428 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2430 * w32proc.c (waitpid): Remove unused label get_result.
2432 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2434 * makefile.w32-in (SYSWAIT_H): New macro.
2435 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2436 ($(BLD)/sysdep.$(O)): Update dependencies.
2438 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2440 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2441 * callproc.c (relocate_fd): Assume F_DUPFD.
2442 * emacs.c, term.c (O_RDWR): Remove.
2443 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2444 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2445 * nsterm.m: Assume <fcntl.h> exists.
2446 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2447 (create_pty, Fmake_network_process, server_accept_connection)
2448 (wait_reading_process_output, init_process_emacs):
2450 (wait_reading_process_output): Put in a special case for WINDOWSNT
2451 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2452 It's not clear this is needed, but it's a more-conservative change.
2453 (create_process): Assume FD_CLOEXEC.
2454 (create_process, create_pty): Assume O_NOCTTY.
2455 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2456 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2457 Omit if not DOS_NT, since F_GETFL is not defined there.
2458 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2459 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2461 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2462 lack it, since gnulib guarantees this.
2463 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2465 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2467 * w32.c (faccessat): Pretend that directories have the execute bit
2468 set. Emacs expects that, e.g., in files.el:cd-absolute.
2470 * w32proc.c (create_child): Don't clip the PID of the child
2471 process to fit into an Emacs integer, as this is no longer a
2473 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2474 reaping only the process specified by PID argument, if that is
2475 positive. Use PID instead of dead_child to know which process to
2476 reap. Wait for the child to die only if WNOHANG is not in
2478 (sys_select): Don't set dead_child.
2480 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2481 as it is no longer needed.
2483 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2485 (record_child_status_change): Remove the setting of
2486 record_at_most_one_child for the !WNOHANG case.
2488 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2490 Fix problems in ns port found by static checking.
2491 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2492 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2493 not to process group.
2494 (ns_select): Use emacs_write, not write, as that's more robust
2495 in the presence of signals.
2496 (fd_handler:): Check for read errors.
2498 2012-11-16 Glenn Morris <rgm@gnu.org>
2500 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2502 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2504 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2506 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2508 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2509 use the same value of thread handle.
2510 (start_timer_thread): If the timer thread exited (due to error),
2511 clean up by closing the two handles it used. Duplicate the caller
2512 thread's handle here, so it gets duplicated only once, when
2513 launching the timer thread. Set priority of the timer thread, not
2515 (getitimer): Don't duplicate the caller thread's handle here.
2518 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2520 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2523 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2525 Remove no-longer-used pty_max_bytes variable.
2526 * process.c (pty_max_bytes): Remove; unused.
2527 (send_process): Do not set it.
2529 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2531 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2532 Update dependencies.
2534 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2536 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2537 This follows up on the 2012-09-29 patch that removed indirection
2538 for the 'function' field. Reported by Sergey Vinokurov in
2539 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2541 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2543 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2544 different name, as the MS runtime does not have such a function,
2545 and probably never will.) All callers changed. Ignore DIRFD
2546 value if PATH is an absolute file name, to match Posix spec
2547 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2550 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2552 * xdisp.c (echo_area_display, redisplay_internal):
2553 Omit redundant check whether frame_garbaged is set.
2555 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2557 Use faccessat, not access, when checking file permissions (Bug#12632).
2558 This fixes a bug that has been present in Emacs since its creation.
2559 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2560 which must set some sort of record. (Torek's bug report was against
2561 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2562 same common flaw.) See Torek's Usenet posting
2563 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2564 Posted: Fri Apr 8 14:18:56 1983.
2565 * Makefile.in (LIB_EACCESS): New macro.
2567 * callproc.c (init_callproc):
2568 * charset.c (init_charset):
2569 * fileio.c (check_existing, check_executable, check_writable)
2571 * lread.c (openp, load_path_check):
2572 * process.c (allocate_pty):
2574 Use effective UID when checking permissions, not real UID.
2575 * callproc.c (init_callproc):
2576 * charset.c (init_charset):
2577 * lread.c (load_path_check, init_lread):
2578 Test whether directories are accessible, not merely whether they exist.
2579 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2580 * fileio.c (check_existing, check_executable, check_writable)
2582 Use symbolic names instead of integers for the flags, as they're
2584 (check_writable): New arg AMODE. All uses changed.
2585 Set errno on failure.
2586 (Ffile_readable_p): Use faccessat, not stat + open + close.
2587 (Ffile_writable_p): No need to call check_existing + check_writable.
2588 Just call check_writable and then look at errno. This saves a syscall.
2589 dir should never be nil; replace an unnecessary runtime check
2590 with an eassert. When checking the parent directory of a nonexistent
2591 file, check that the directory is searchable as well as writable, as
2592 we can't create files in unsearchable directories.
2593 (file_directory_p): New function, which uses 'stat' on most platforms
2594 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2595 (Ffile_directory_p, Fset_file_times): Use it.
2596 (file_accessible_directory_p): New function, which uses a single
2597 syscall for efficiency.
2598 (Ffile_accessible_directory_p): Use it.
2599 * xrdb.c (file_p): Use file_directory_p.
2600 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2601 * lread.c (openp): When opening a file, use fstat rather than
2602 stat, as that avoids a permissions race. When not opening a file,
2603 use file_directory_p rather than stat.
2604 (dir_warning): First arg is now a usage string, not a format.
2605 Use errno. All uses changed.
2606 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2607 that merely introduced a race.
2608 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2609 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2610 and similarly for the other O_* flags.
2611 * w32.c (sys_faccessat): Rename from sys_access and switch to
2612 faccessat's API. All uses changed.
2613 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2614 (magic_db): Rename from magic_file_p.
2615 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2616 char *, so that we don't have to test for file existence
2617 separately from opening the file for reading. This removes a race
2618 fixes a permission-checking problem, and simplifies the code.
2620 (file_p): Remove; no longer needed.
2622 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2624 Omit glyphs initialization at startup.
2625 * dispnew.c (glyphs_initialized_initially_p): Remove.
2626 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2627 (Fredraw_frame): Move actual code from here...
2628 (redraw_frame): ...to here. Add eassert. Adjust comment.
2629 (Fredraw_display): Use redraw_frame.
2630 * xdisp.c (clear_garbaged_frames): Likewise.
2632 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2634 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2635 passed to pint2str and pint2hrstr to be at most the size of the
2636 frame's decode_mode_spec_buffer. This avoids crashes with very
2637 large values of FIELD_WIDTH argument to decode_mode_spec.
2640 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2642 Fix a race with verify-visited-file-modtime (Bug#12863).
2643 Since at least 1991 Emacs has ignored an mtime difference of no
2644 more than one second, but my guess is that this was to work around
2645 file system bugs that were fixed long ago. Since the race is
2646 causing problems now, let's remove that code.
2647 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2648 whose time stamp is off by no more than a second. Insist that the
2649 file time stamps match exactly.
2651 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2653 * frame.h (struct frame): Convert external_tool_bar member to
2654 1-bit unsigned bitfield.
2655 * termhooks.h (struct terminal): Remove mouse_moved member since
2656 all users are long dead. Adjust comment on mouse_position_hook.
2658 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2660 Simplify by using FOR_EACH_FRAME here and there.
2661 * frame.c (next_frame, prev_frame, other_visible_frames)
2662 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2663 * w32term.c (x_window_to_scroll_bar): Likewise.
2664 * window.c (window_list): Likewise.
2665 * xdisp.c (x_consider_frame_title): Likewise.
2666 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2667 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2668 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2669 * xmenu.c (menubar_id_to_frame): Likewise.
2670 * xselect.c (frame_for_x_selection): Likewise.
2671 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2672 (x_window_to_menu_bar): Likewise.
2673 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2675 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2677 * data.c (Qdefalias_fset_function): Now static.
2679 Another tweak to vectorlike_header change.
2680 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2681 Remove, and replace all uses with ...
2682 (next_in_free_list, set_next_in_free_list):
2683 New functions, which respect C's aliasing rules better.
2685 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2687 * window.c (list4i): Rename from 'quad'. All uses changed.
2688 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2690 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2692 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2693 warning about mixing declarations and code in ISO C90.
2695 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2697 * window.c (Fsplit_window_internal): Set combination limit of
2698 new parent window to t iff Vwindow_combination_limit is t;
2699 fixing a regression introduced with the change from 2012-09-22.
2700 (Fset_window_combination_limit): Fix doc-string.
2702 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2704 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2705 amount when the scroll margins are too large. When scrolling
2706 backwards in the buffer, give up if cannot reach point or the
2707 scroll margin within a reasonable number of screen lines.
2708 Fixes point position in window under scroll-up/down-aggressively when
2709 point is positioned many lines beyond the window top/bottom.
2712 * ralloc.c (relinquish): If real_morecore fails to return memory
2713 to the system, don't crash; instead, leave the last heap
2714 unchanged and return. (Bug#12774)
2716 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2718 * lisp.h (AUTOLOADP): New macro.
2719 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2720 * data.c (Ffset): Remove special ad-advice-info handling.
2721 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2723 (Finteractive_form): Simplify.
2724 (Fquo): Don't insist on having at least 2 arguments.
2725 (Qdefalias_fset_function): New var.
2727 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2729 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2731 * nsfont.m (Qcondensed, Qexpanded): New variables.
2732 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2733 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2735 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2737 Fix recently introduced crash on MS-Windows (Bug#12839).
2738 * w32term.h (struct scroll_bar): Use convenient header.
2739 (SCROLL_BAR_VEC_SIZE): Remove.
2740 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2742 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2744 Tweak last vectorlike_header change.
2745 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2746 vectorlike object on the free list. This is introduced to avoid
2747 some (but not all) pointer casting and aliasing problems, see
2748 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2749 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2751 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2753 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2755 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2756 been removed, so remove them here also.
2758 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2760 * doc.c (Fdocumentation): Handle new property
2761 dynamic-docstring-function to replace the old ad-advice-info.
2763 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2765 * fns.c (Qeql, hashtest_eq): Now static.
2767 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2769 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2770 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2771 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2772 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2774 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2776 Use same hash function for hashfn_profiler as for hash_string etc.
2777 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2778 * lisp.h (sxhash_combine): New inline function, with the contents
2779 of the old SXHASH_COMBINE.
2780 * profiler.c (hashfn_profiler): Use it, instead of having a
2781 special hash function containing a comparison that always yields 1.
2783 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2785 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2786 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2787 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2790 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2792 * image.c (xpm_make_color_table_h): Fix compiler error because
2793 make_hash_table changed.
2795 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2797 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2799 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2801 Use ad-hoc comparison function for the profiler's hash-tables.
2802 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2803 (make_log): Use them.
2804 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2805 call Fequal any more.
2806 (Ffunction_equal): New function.
2807 (cmpfn_profiler, hashfn_profiler): New functions.
2808 (syms_of_profiler): Initialize them.

2814 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2815 (hash_lookup, hash_remove_from_table): Move assertion checking of
2816 hashfn result here. Check hash-equality before calling cmpfn.
2817 (Fmake_hash_table): Adjust call to make_hash_table.
2818 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2819 (syms_of_fns): Initialize them.

2824 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2826 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2828 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2829 value of w32-scroll-lock-modifier is neither nil nor one of the
2830 known key modifiers. (Bug#12806)
2832 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2834 Shrink struct vectorlike_header to the only size field.
2835 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2837 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2838 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2839 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2840 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2841 information from the vector header. Adjust comment.

2851 (enum mem_type): Adjust comment.
2852 (NEXT_IN_FREE_LIST): New macro.
2853 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2854 (Fmake_bool_vector): Likewise.
2855 (struct large_vector): New type to represent allocation unit for
2856 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2857 (large_vectors): Change type to struct large_vector.
2858 (allocate_vector_from_block): Simplify.
2859 (PSEUDOVECTOR_NBYTES): Replace with...
2860 (vector_nbytes): ...new function. Adjust users.
2861 (sweep_vectors): Adjust processing of large vectors.
2862 (allocate_vectorlike): Likewise.
2863 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2864 Add easserts. Adjust XSETPVECTYPESIZE usage.
2865 (allocate_buffer): Use BUFFER_PVEC_INIT.
2866 (live_vector_p): Adjust to match large vector.
2867 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2868 * buffer.h (struct buffer): Add next member.
2869 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2871 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2877 (xvecsize): New command.
2879 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2881 * keyboard.c (event_to_kboard): Do not dereference
2882 frame_or_window field of SELECTION_REQUEST_EVENT
2883 and SELECTION_CLEAR_EVENT events (Bug#12814).
2884 * xterm.h (struct selection_input_event): Adjust comment.
2886 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2888 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2889 such as Scroll Lock, if the respective keys are treated as
2890 function keys, not as modifiers. This avoids destroying non-ASCII
2891 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2893 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2895 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2897 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2899 Restore some duplicate definitions (Bug#12814).
2900 This undoes part of the 2012-11-03 changes. Some people build
2901 with plain -g rather than with -g3, and they need the duplicate
2902 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2903 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2904 Define as macros, as well as as enums or as constants.
2906 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2908 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2909 to keypad keys (Bug#12816).
2911 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2913 Minor adjustments of recently-changed frame functions.
2914 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2915 known to be a frame (we're in the FRAMEP branch).
2916 * lisp.h (Qframep): Remove decl. frame.h declares this.
2917 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2918 since they're meant for Lisp fixnum values.
2920 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2922 * window.c (Fwindow_combination_limit): Revert to the only
2923 required argument and adjust docstring as suggested in
2924 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2925 by Martin Rudalics <rudalics@gmx.at>.
2927 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2929 Widely used frame validity and checking functions.
2930 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2931 * frame.c (decode_live_frame, decode_any_frame): New functions.
2932 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2933 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2934 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2935 (Fframe_pointer_visible_p): Use decode_any_frame.

2937 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2938 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2939 (Fframe_focus): Likewise. Allow zero number of arguments.
2941 (frame_buffer_list, frame_buffer_predicate): Remove.
2942 * lisp.h (frame_buffer_predicate): Remove prototype.
2943 * buffer.c (Fother_buffer): Use decode_any_frame.
2944 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2945 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2946 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2947 (Fclose_font, Ffont_info): Use decode_live_frame.
2948 * fontset.c (check_fontset_name): Likewise.
2949 * terminal.c (Fframe_terminal): Likewise.
2950 * w32fns.c (check_x_frame): Likewise.
2951 * window.c (Fminibuffer_window, Fwindow_at)
2952 (Fcurrent_window_configuration): Likewise.
2953 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2954 Likewise. Allow zero number of arguments. Adjust docstring.
2955 * dispnew.c (Fredraw_frame): Likewise.
2956 * xfaces.c (frame_or_selected_frame): Remove.
2957 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2958 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2959 (Fframe_face_alist): Use decode_live_frame.
2960 * xfns.c (check_x_frame): Likewise.
2962 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2964 * window.c (quad): New function.
2965 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2966 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2967 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2968 (Fwindow_line_height): Use it.
2969 (Fwindow_fringes): Use list3.
2970 (Fwindow_scroll_bars): Use list4.
2971 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2972 (Fwindow_combination_limit): Allow zero number of arguments.
2974 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2976 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2978 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2979 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2980 file descriptor 2 for standard error. (Bug#12805)
2982 2012-11-05 Chong Yidong <cyd@gnu.org>
2984 * process.c (wait_reading_process_output): Revert previous change.
2986 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2988 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2989 This removes code that has been obsolete since around 1990.
2990 * callproc.c (Fcall_process):
2992 * process.c (create_process):
2993 * term.c (dissociate_if_controlling_tty):
2994 Assume setsid exists.
2995 * callproc.c (child_setup): Assume setpgid exists and behaves as
2996 per POSIX.1-1988 or later.
2997 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2998 * emacs.c (shut_down_emacs):
2999 * sysdep.c (sys_suspend, init_foreground_group):
3000 Assume getpgrp behaves as per POSIX.1-1998 or later.
3001 * msdos.c (setpgrp): Remove.
3002 (tcgetpgrp, setpgid, setsid): New functions.
3003 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3004 * term.c (no_controlling_tty): Remove; unused.
3005 * w32proc.c (setpgrp): Remove.
3006 (setsid, tcgetpgrp): New functions.
3008 Simplify by assuming __fpending.
3009 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3010 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3011 Do not assume that __fpending's result fits in int.
3013 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3015 Remove EMACS_OUTQSIZE+sleep hack.
3016 * dispnew.c (update_frame_1): Remove hack for terminals slower
3017 than 2400 bps, which throttled Emacs by having it sleep.
3018 This code hasn't worked since at least 2007, when the multi-tty stuff
3019 was added, and anyway those old terminals are long dead.
3020 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3021 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3023 Fix data-loss with --version (Bug#9574).
3024 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3025 as we can't assume that emacs_strerror is initialized, and strerror
3026 is good enough here.
3027 (main): Invoke atexit earlier, to catch earlier instances of
3028 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3030 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3032 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3033 (keyDown): Remap keypad keys to X11 virtual key codes.
3035 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3037 Fix data-loss with --batch (Bug#9574).
3038 * emacs.c: Include <close-stream.h>.
3039 (close_output_streams): New function.
3040 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3041 and handles errors appropriately.
3042 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3045 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3046 The symptom is a diagnostic "GLib-WARNING **: In call to
3047 g_spawn_sync(), exit status of a child process was requested but
3048 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3049 waitpid(), so exit status can't be returned." The diagnostic
3050 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3051 The real bug is a race condition between Emacs and glib: Emacs
3052 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3053 so that glib can't find it. Work around the bug by invoking
3054 waitpid only on subprocesses that Emacs itself creates.
3055 * process.c (create_process, record_child_status_change):
3056 Don't use special value -1 in pid field, as the caller now must
3057 know the pid rather than having the callee infer it.
3058 The inference was sometimes incorrect anyway, due to another race.
3059 (create_process): Set new 'alive' member if child is created.
3060 (process_status_retrieved): New function.
3061 (record_child_status_change): Use it.
3062 Accept negative 1st argument, which means to wait for the
3063 processes that Emacs already knows about. Move special-case code
3064 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3065 processes that have already been waited for, by testing and
3066 clearing new 'alive' member.
3067 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3068 now does this internally.
3069 (handle_child_signal): Let record_child_status_change do all
3070 the work, since we do not want to reap all exited child processes,
3071 only the child processes that Emacs itself created.
3072 * process.h (Lisp_Process): New boolean member 'alive'.
3074 Omit duplicate definitions no longer needed with gcc -g3.
3075 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3076 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3077 Define only as macros. There's no longer any need to also define
3078 these symbols as enums or as constants, since we now assume
3079 gcc -g3 when debugging.
3081 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3083 * lisp.mk: Adjust comments to the fact that term/internal is now
3084 loaded from loadup.el.
3086 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3087 (msdos_fatal_signal): New function.
3088 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3091 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3092 for GCC versions before 4.
3093 (emacs_raise): Define to call msdos_fatal_signal.
3095 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3096 iterator when starting in the middle of a display or overlay
3099 2012-11-03 Chong Yidong <cyd@gnu.org>
3101 * process.c (wait_reading_process_output): Clean up the last
3104 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3106 * process.c (wait_reading_process_output): Avoid a race condition
3107 with SIGIO delivery (Bug#11536).
3109 2012-11-03 Chong Yidong <cyd@gnu.org>
3111 * buffer.c (cursor_type): Untabify docstring.
3113 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3115 * frame.h (struct frame): Drop can_have_scroll_bars member
3116 which is meaningless for a long time. Adjust comments.
3117 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3118 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3120 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3122 * window.c (decode_next_window_args): Update window arg after
3123 calling decode_live_window and so fix crash reported at
3124 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3125 by Juanma Barranquero <lekktu@gmail.com>.
3126 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3127 * font.c (Ffont_at): Likewise.
3129 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3131 * widget.c (resize_cb): New function.
3132 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3133 (EmacsFrameResize): Check if all is up to date before changing frame
3136 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3138 Implement backtrace output for fatal errors on MS-Windows.
3139 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3140 (BACKTRACE_LIMIT_MAX): New macro.
3141 (w32_backtrace): New function.
3142 (emacs_abort): Use w32_backtrace when the user chooses not to
3143 attach a debugger. Update the text of the abort dialog.
3145 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3147 Window-related stuff cleanup here and there.
3148 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3149 Use decode_any_window.
3150 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3151 * xdisp.c (Fformat_mode_line): Likewise.
3152 * font.c (Ffont_at): Use decode_live_window.
3153 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3154 * window.c (decode_next_window_args): Likewise.
3155 (decode_any_window): Remove static.
3156 * window.h (decode_any_window): Add prototype.
3157 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3158 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3161 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3163 Remove pad from struct input_event.
3164 * termhooks.h (struct input_event): Remove padding field.
3166 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3167 member is never cons for a long time. Adjust comment.
3168 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3169 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3170 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3171 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3173 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3175 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3177 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3179 Fix crash when using Emacs as commit editor for git (Bug#12697).
3180 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3181 and it is configured in conf_post.h.
3182 (Fcall_process): Don't invoke both setsid and setpgid; the former
3183 is enough, if it exists.
3184 * callproc.c (Fcall_process, child_setup):
3185 * process.c (create_process): Use setpgid.
3186 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3188 * dispnew.c (init_display): Initialize the foreground group
3189 if we are running a tty display.
3190 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3191 * lisp.h (init_foreground_group): New decl.
3192 * sysdep.c (inherited_pgroup): New static var.
3193 (init_foreground_group, tcsetpgrp_without_stopping)
3194 (narrow_foreground_group, widen_foreground_group): New functions.
3195 (init_sys_modes): Narrow foreground group.
3196 (reset_sys_modes): Widen foreground group.
3198 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3200 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3202 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3204 * minibuf.c (read_minibuf): Restore current buffer since
3205 choose_minibuf_frame calling Fset_frame_selected_window may
3206 change it (Bug#12766).
3208 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3210 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3212 2012-10-30 Kenichi Handa <handa@gnu.org>
3214 * font.c (Ffont_at): If WINDOW is specified and it is not
3215 displaying the current buffer, signal an error.
3217 2012-10-29 Daniel Colascione <dancol@dancol.org>
3219 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3220 In preparation for fixing bug#12739, move these functions from
3223 * coding.h, coding.c: ... to here, and compile them only when
3224 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3225 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3227 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3229 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3230 (timer_loop, getitimer, setitimer): Use it instead of
3231 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3233 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3236 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

3250 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3252 Avoid overflow in w32 implementation of interval timers.
3253 When possible, for ITIMER_PROF count only times the main thread
3255 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3256 'volatile ULONGLONG' types. All the other data which was
3257 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3258 (GetThreadTimes_Proc): New typedef.
3259 (w32_get_timer_time): New function, returns a suitable time value
3261 (timer_loop): Enter critical section when accessing ULONGLONG
3262 values of the itimer_data struct, as these accesses are no longer
3263 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3264 Remove unused variable.
3265 (init_timers): Initialize s_pfn_Get_Thread_Times.
3266 (start_timer_thread): Don't assign itimer->caller_thread here.
3267 (getitimer): Assign itimer->caller_thread here.

3273 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3274 mouse movement events if the menu bar is active. This avoids
3275 producing a busy "hour-glass" cursor by Windows if the mouse
3276 pointer is positioned over a tooltip shown for some menu item.
3278 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>

3281 * emacs.c (shut_down_emacs) [!DOS_NT]:
3282 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3283 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3284 Use pid_t, not int, to store process IDs, as 'int'
3285 is not wide enough on a few platforms (e.g., AIX and IRIX).
3287 2012-10-23 Kenichi Handa <handa@gnu.org>
3289 The following change is to make face-font-rescale-alist work

3315 * frame.c (Fmouse_position, Fmouse_pixel_position):
3316 * xdisp.c (produce_stretch_glyph):
3317 Declare local vars only when they're needed.
3318 This is clearer and avoids a warning on OpenBSD about unused vars.

3322 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3323 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3324 as our definition clashes with OpenBSD's.
3325 * xfaces.c (load_face_colors, check_lface_attrs)
3326 (get_lface_attributes_no_remap, get_lface_attributes)
3327 (lface_fully_specified_p, x_supports_face_attributes_p)
3328 (tty_supports_face_attributes_p, face_fontset, realize_face)
3329 (realize_x_face, realize_tty_face):
3330 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3331 merely Lisp_Object *. This is more informative and avoids
3332 a warning on OpenBSD about accessing beyond an object's size.
3334 2012-10-20 Chong Yidong <cyd@gnu.org>
3336 * lread.c (Fload): Doc fix (Bug#12592).

3362 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3363 (staticpro): If we run out of staticpro slots, die with an
3364 informative error instead of just calling emacs_abort.

3626 the same pointer-to-int (now pointer-to-boolean) &input_pending,

3677 'is_tooltip_frame', to avoid confusion with its global namesake.
3679 2012-10-08 Daniel Colascione <dancol@dancol.org>
3681 * xdisp.c (start_hourglass): Call w32_note_current_window when
3682 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3683 build that caused Emacs to display the hourglass cursor forever.
3685 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3686 which is broken under remote desktop, calculate the number of
3687 colors available for a display based on the display's number of

3718 ($(BLD)/w32menu.$(O)):
3719 ($(BLD)/w32proc.$(O)): Add w32common.h.
3721 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3723 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3725 2012-10-08 Daniel Colascione <dancol@dancol.org>
3727 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3728 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3729 accidental message numbering hole. Change other messages to
3732 * w32select.h (HAVE_W32SELECT): Remove.
3734 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3735 w32common.h instead of w32heap.h.
3737 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3738 (get_allocation_unit, get_processor_type, get_w32_major_version)
3739 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3740 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3741 (OS_NT, os_subtype, cache_system_info): Move declarations to
3744 * w32heap.c: Include w32common.h.
3745 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3746 (w32_minor_version, w32_build_number, w32_subtype):
3747 Remove duplicate definitions.
3749 * w32fns.c: Include w32common.h; include w32heap.h only in
3752 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3753 Use `report_file_error' instead of `error' in order to better
3754 inform users of what went wrong. Increase NTGUI_UNICODE file
3755 dialog box file name length to 32k, the maximum allowed by the NT
3758 * w32common.h: New file.
3759 (ROUND_UP, ROUND_DOWN, get_page_size)
3760 (get_allocation_unit, get_processor_type, get_w32_major_version)
3761 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3762 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3763 (OS_NT, os_subtype, cache_system_info): Move here.
3765 * unexw32.c, unexcw.c: Include w32common.h.
3767 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3768 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3769 to call syms_of_w32select.
3771 * cygw32.h: Remove obsolete EXFUN declarations.
3773 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3775 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3776 of w32inevt.o from SOME_MACHINE_OBJECTS.
3778 2012-10-08 Daniel Colascione <dancol@dancol.org>
3780 * image.c: Permanent fix for JPEG compilation issue --- limit
3781 jpeglib `boolean' redefinition to Cygwin builds.
3783 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3785 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3787 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3790 2012-10-08 Daniel Colascione <dancol@dancol.org>
3792 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3793 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3794 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3795 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3796 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3797 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3798 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3799 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3800 now a supported configuration.
3802 * Makefile.in: consolidate image variables into LIBIMAGE; add
3803 W32_OBJ and W32_LIBS. Compile new files.
3806 (_DebPrint) declare tracing facility for W32 debugging. We need
3807 to unify tracing later.
3809 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3810 unconditional use of W32 Unicode functions. Cygwin runs only on
3811 100% Unicode operating systems.
3813 * cygw32.c: New file. Define Cygwin-specific facilities.
3814 (Fcygwin_convert_path_to_windows)
3815 (Fcygwin_convert_path_from_windows): New user functions for
3816 accessing Cygwin path-munging routines.
3818 * cygw32.h: New file.
3819 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3820 UTF-16LE strings temporarily inside non-Lisp-visible string
3823 (w32_strerror): Just what it says on the tin.
3825 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3826 also run for Cygwin; both systems have the same problem with using
3827 GUI facilities in a forked child. Also call syms_of_cygw32,
3828 syms_of_w32select in correct places.
3830 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3831 needs fork-then-exec for daemon launching.
3833 * font.h: Include frame.h.
3835 * image.c: Use the image library cache machinery only when we're
3836 compiling for native WINDOWSNT; Cygwin can use shared libraries
3837 like any other Unixlike system.
3839 * keyboard.c: Clarify a comment regarding the input loop.
3841 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3842 functions directly instead of trying to detect at runtime that our
3843 host operating system supports them. We make this change for two
3844 reasons: Cygwin lacks support for the multibyte character
3845 conversion functions used by the legacy menu code, and Cygwin
3846 never needs to rely on non-Unicode APIs.
3848 * unexw32.c (hinst): Declare extern.
3850 * w32.c: Change header order;
3851 (w32_strerror): Move to w32fns.c because we need it for
3852 non-WINDOWSNT builds.
3854 * w32.h: Add #error macro to make sure we don't include w32.h for
3855 Cygwin builds. Remove w32select declarations.
3857 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3858 w32fns.c. w32console.c is WINDOWSNT-only.
3860 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3861 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3863 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3864 (w32_major_version, w32_minor_version, w32_build_number)
3865 (os_subtype, sound_type): Define here
3866 (w32_defined_color): Make color parameter const for consistency
3867 with other _defined_color functions.
3868 (w32_createwindow): Unconditionally call w32_init_class instead of
3869 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3870 through the code is complex and unnecessary because class
3871 registration is practically free.
3872 (w32_name_of_message): New EMACSDEBUG-only function.
3873 (Fset_message_beep): Move here
3874 (Fx_open_connection): Require that the display name for Windows be
3875 "w32" for consistency, emacsclient disambiguation, and maybe, one
3876 day, multi-window-system support.
3877 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3878 Cygwin files for W32 GUI facilities, since these clearly don't
3879 expect Cygwin names.
3880 (_DebPrint): Define.
3881 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3882 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3883 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3884 (w32_last_error): Remove.
3886 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3888 * w32heap.c (syspage_mask): Declare here.
3889 (cache_system_info): Remove.
3891 * w32inevt.c (faked_key): Define globally, not statically.
3892 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3893 (w32_console_toggle_lock_key): Move to w32fns.c.
3895 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3897 * w32proc.c (_DebPrint): Move to w32fns.c.
3898 * w32select.c: Include string.h, stdio.h for Cygwin.
3899 * w32select.h: New File.
3901 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3903 (w32_message_fd): New variable. Under Cygwin, holds the file
3904 descriptor the system used to tell us about pending thread
3907 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3908 that prevented compilation under non-WINDOWSNT systems.
3910 (w32_initialize): Open /dev/windows and assign it to
3911 w32_message_fd. Provide w32 feature.
3913 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3914 (WM_EMACS_INPUT_READY): add.
3915 (prepend_msg, w32_message_fd): Declare globally.
3918 (keyboard_handle): Use only when WINDOWSNT.
3919 (notify_msg_ready): New function. Posts a message to the main
3920 thread's message queue under CYGWIN, which wakes up the main
3921 thread from select(2) by making the /dev/windows file descriptor
3922 ready. Under WINDOWSNT, it sets an event the same way the old
3925 (post, prepend_msg): Actually call notify_msg_ready instead of
3926 setting the input event directly.
3928 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3930 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3931 but it still has blocs in it, don't return it to the system,
3932 instead of aborting. (Bug#12402)
3934 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3936 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3938 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3939 MAC_OS_X_VERSION_10_6.
3940 (syms_of_nsterm): Remove comment about Panther and above for
3942 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3943 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3944 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3946 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3947 MAC_OS_X_VERSION_10_4.
3949 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3950 MAC_OS_X_VERSION_10_2.
3952 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3954 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3955 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3957 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3958 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3959 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3960 Remove ns_in_resize check.
3961 (ns_clear_frame_area): Remove resize handle code.
3963 * nsfns.m (ns_in_resize): Remove.
3964 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3965 Remove ns_in_resize check.
3967 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3969 Improve sys_siglist detection.
3970 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3971 defined as a macro, as is done in Solaris.
3972 (sys_siglist_entries): New macro.
3973 (save_strsignal): Use it.
3974 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3975 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3977 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3979 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3980 fullscreen/Fullscreen.
3982 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3983 tobar_height is new.
3985 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3986 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3987 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3988 (windowDidResize:): Check for correct window if old style fullscreen.
3989 Capitalize word in comment. Remove incorrect comment.
3990 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3991 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3992 error in drawing background.
3993 (toggleFullScreen:): Remove comment. Rearrange calls.
3994 Set toolbar values to zero, save old height in tobar_height.
3995 Restore tool bar height when leaving fullscreen.
3996 (canBecomeMainWindow): New function.
3998 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4000 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4002 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4004 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4006 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4007 that time stamps of directories could also be changed.
4008 Don't request the too broad GENERIC_WRITE, only the more restrictive
4009 FILE_WRITE_ATTRIBUTES access rights.
4011 * fileio.c (Fset_file_times): Special-case ignoring errors for
4012 directories only on MSDOS, not on MS-Windows.
4014 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4016 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4018 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4020 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4021 see whether CreateFile failed.
4023 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4025 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4026 to avoid similar races.
4027 * keyboard.c (pending_signals): Now bool, not int.
4029 Port timers to OpenBSD, plus check for timer failures.
4030 OpenBSD problem reported by Han Boetes.
4031 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4033 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4034 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4035 like OpenBSD, which has timer_settime but does not declare it.
4036 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4037 whether to use itimerspec-related primitives. All uses of
4038 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4040 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4042 * profiler.c (handle_profiler_signal): Fix a malloc race
4043 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4045 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4047 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4049 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4051 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4052 consistent with the change in return value of 'safe_strsignal'.
4054 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4056 Prefer plain 'static' to 'static inline' (Bug#12541).
4057 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4058 (bidi_set_sor_type, bidi_push_embedding_level)
4059 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4060 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4061 (bidi_cache_search, bidi_cache_ensure_space)
4062 (bidi_cache_iterator_state, bidi_cache_find)
4063 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4064 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4065 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4066 Now 'static', not 'static inline'.
4068 Count overruns when profiling; change units to ns.
4069 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4070 Give extra weight to samples after overruns, to attempt to count
4071 the time more accurately.
4072 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4073 the underlying primitives nominally do ns.
4074 (Fprofiler_cpu_start): Document the change. Mention that
4075 the sampling intervals are only approximate.
4077 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4079 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4081 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4082 case for the special 0 coding-system.
4084 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4085 (Fmake_overlay): Remove redundant tests.
4086 (fix_start_end_in_overlays): Remove redundant recentering.
4088 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4090 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4091 Update dependencies.
4093 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4095 Fix a malloc race condition involving strsignal.
4096 A signal can arrive in the middle of a malloc, and Emacs's signal
4097 handler can invoke strsignal, which can invoke malloc, which is
4098 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4099 Fix it by altering the signal handler so that it does not invoke
4101 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4102 * process.c (status_message): Use const pointer, in case strsignal
4103 is #defined to safe_strsignal.
4104 * sysdep.c (sys_siglist, init_signals): Always define and
4105 initialize a substitute sys_siglist if the system does not define
4106 one, even if HAVE_STRSIGNAL.
4107 (safe_strsignal): Rename from strsignal. Always define,
4108 using sys_siglist. Return a const pointer.
4109 * syssignal.h (safe_strsignal): New decl.
4110 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4112 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4114 * w32proc.c (timer_loop): Fix code that waits for timer
4115 expiration, to avoid high CPU usage.
4117 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4119 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4120 (sweep_weak_table): Remove redundant prototypes.
4122 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4124 * emacs.c: Move the inclusion of TERM_HEADER after including
4125 windows.h on WINDOWSNT. This avoids compilation problems with
4128 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4130 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4131 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4132 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4133 as the previous version used 'void *'.
4135 * ralloc.c (ROUNDUP): Fix last change.
4136 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4139 * w32proc.c <disable_itimers>: New static flag.
4140 (init_timers): Initialize it to zero, after creating the critical
4141 sections used by the timer threads.
4142 (term_timers): Set to 1 before deleting the critical sections.
4143 (getitimer, setitimer): If disable_itimers is non-zero, return an
4144 error indication without doing anything. Reported by Fabrice
4145 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4146 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4148 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4151 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4152 term_ntproc after all the other bookkeeping, to get timers working
4153 as long as possible.
4155 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4157 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4158 Suggested by Juri Linkov in
4159 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4161 Prefer plain 'static' to 'static inline' (Bug#12541).
4162 With static functions, modern compilers inline pretty well by
4163 themselves; advice from programmers often hurts as much as it helps.
4164 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4165 this change shrinks the text size of the Emacs executable by 1.1%
4166 without affecting CPU significantly in my benchmark.
4167 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4168 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
4169 (mark_maybe_object, mark_maybe_pointer, bounded_number):
4170 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
4171 (bset_auto_fill_function, bset_auto_save_file_format)
4172 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

4460 (handle_profiler_signal): Rename from sigprof_handler_1,
4461 for consistency with other handlers. Do not check whether
4462 cpu_log is a hash-table if garbage collecting, since it

4465 for consistency with other handlers.
4466 (setup_cpu_timer): New function, with much of what used to be in

4468 Prefer timer_settime if available, and prefer
4469 thread cputime clocks, then process cputime clocks, then
4470 monotonic clocks, to the old realtime clock. Use make_timeval
4471 to round more-correctly when falling back to setitimer.
4472 (Fprofiler_cpu_start): Use it.
4473 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4539 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4540 Since this stuff is now private to charset.c, there's no need for
4541 a public macro and no need to inline by hand.

4651 now return bool, not int. All uses changed.
4652 * image.c: Omit unnecessary static decls.
4653 (x_create_bitmap_mask, x_build_heuristic_mask):
4654 Return void, not int, since callers don't care about the return value.

4689 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4691 Move pid_t related decls out of lisp.h.
4692 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4693 (interruptible_wait_for_termination):
4694 Move these decls from lisp.h to syswait.h, since they use pid_t.
4695 Needed on FreeBSD; see Herbert J. Skuhra in
4696 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4697 * callproc.c: Include syswait.h.

4717 Use bool for boolean.
4718 * gtkutil.c (xg_update_frame_menubar):

4724 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4726 * makefile.w32-in (BLOCKINPUT_H): Remove.

4743 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4745 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4746 fatal_error_backtrace.
4748 * w32proc.c (sys_kill): Undo last change: don't do anything when
4749 invoked to deliver SIGABRT to our own process. This is now
4750 handled by emacs_raise.
4752 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4754 * w32term.c (w32_read_socket): Remove leftover reference to
4755 interrupt_input_pending.
4757 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4759 Do not use SA_NODEFER.
4760 Problem reported by Dani Moncayo in
4761 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4763 * sysdep.c (emacs_abort): Do not reset signal handler.
4764 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4765 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4766 wanted even on POSIXish hosts, and it doesn't work on Windows.
4768 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4770 * xterm.c (x_term_init): Call fixup_locale before and after calling
4771 gtk_init (Bug#12392).
4773 2012-09-23 Chong Yidong <cyd@gnu.org>
4775 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4776 Vdynamic_library_alist.
4778 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4779 (Fgnutls_available_p): Caller changed.
4781 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4782 (Flibxml_parse_xml_region): Likewise.
4784 * dispextern.h (struct image_type): Remove arg from init function.
4786 * image.c (Finit_image_library, lookup_image_type)
4787 (define_image_type): Remove now-unneeded second arg.
4788 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4789 (init_tiff_functions, init_gif_functions, init_svg_functions):
4790 Arglist and w32_delayed_load calling convention changed.
4791 (gs_type): Remove init_gs_functions; there is no such function.
4792 (valid_image_p, make_image): Fix caller to lookup_image_type.
4794 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4796 Simplify and avoid signal-handling races (Bug#12471).
4798 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4799 Avoid recursive loop if there's a fatal error in the function itself.
4800 * atimer.c (pending_atimers):
4801 * blockinput.h: Don't include "atimer.h"; no longer needed.
4802 (interrupt_input_pending): Remove. All uses removed.
4803 pending_signals now counts both atimers and ordinary interrupts.
4804 This is less racy than having three separate pending-signal flags.
4805 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4807 Rename from their upper-case counterparts BLOCK_INPUT,
4808 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4809 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4810 This makes it easier to access volatile variables more accurately.
4811 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4812 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4813 that's more reliable if the code is buggy and sets
4814 interrupt_input_blocked to a negative value. All uses changed.
4815 * atimer.c (deliver_alarm_signal):
4816 Remove. No need to deliver this to the parent; any thread can
4817 handle this signal now. All uses replaced by underlying handler.
4818 * atimer.c (turn_on_atimers):
4819 * dispnew.c (handle_window_change_signal):
4820 * emacs.c (handle_danger_signal):
4821 * keyboard.c (kbd_buffer_get_event):
4822 Don't reestablish signal handler; not needed with sigaction.
4823 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4825 Rework to avoid unnecessary accesses to volatile variables.
4826 (UNBLOCK_INPUT_TO): Now a function.
4827 (totally_unblock_input, unblock_input): New decls.
4828 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4829 (init_data): Remove. Necessary stuff now done in init_signal.
4830 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4831 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4832 (fatal_error_code): Remove; no longer needed.
4833 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4834 it doesn't always backtrace. All uses changed. No need to reset
4835 signal to default, since sigaction and/or die does that for us now.
4836 Use emacs_raise (FOO), not kill (getpid (), FOO).
4837 (main): Check more-accurately whether we're dumping.
4838 Move fatal-error setup to sysdep.c
4839 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4840 * gtkutil.c (xg_get_file_name, xg_get_font):
4841 Remove no-longer-needed signal-mask manipulation.
4842 * keyboard.c, process.c (POLL_FOR_INPUT):
4843 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4844 * keyboard.c (read_avail_input): Remove.
4845 All uses replaced by gobble_input.
4846 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4847 (kbd_buffer_store_event_hold, gobble_input):
4848 (record_asynch_buffer_change) [USABLE_SIGIO]:
4849 (store_user_signal_events):
4850 No need to mess with signal mask.
4851 (gobble_input): If blocking input and there are terminals, simply
4852 set pending_signals to 1 and return. All hooks changed to not
4853 worry about whether input is blocked.
4854 (process_pending_signals): Clear pending_signals before processing
4855 them, in case a signal comes in while we're processing.
4856 By convention callers now test pending_signals before calling us.
4857 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4858 New functions, to support changes to blockinput.h.
4859 (handle_input_available_signal): Now extern.
4860 (reinvoke_input_signal): Remove. All uses replaced by
4862 (quit_count): Now volatile, since a signal handler uses it.
4863 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4864 All callers changed. Block SIGINT only if not already blocked.
4865 Clear sigmask reliably, even if Fsignal returns, which it can.
4866 Omit unnecessary accesses to volatile var.
4867 (quit_throw_to_read_char): No need to restore sigmask.
4868 * keyboard.c (gobble_input, handle_user_signal):
4869 * process.c (wait_reading_process_output):
4870 Call signal-handling code rather than killing ourselves.
4871 * lisp.h: Include <float.h>, for...
4872 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4873 (pending_signals): Now volatile.
4874 (syms_of_data): Now const if IEEE floating point.
4875 (handle_input_available_signal) [USABLE_SIGIO]:
4876 (terminate_due_to_signal, record_child_status_change): New decls.
4877 * process.c (create_process): Avoid disaster if memory is exhausted
4878 while we're processing a vfork, by tightening the critical section
4880 (send_process_frame, process_sent_to, handle_pipe_signal)
4881 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4883 (send_process): No need for setjmp/longjmp any more, since the
4884 SIGPIPE stuff is now gone. Instead, report an error if errno
4886 (record_child_status_change): Now extern. PID and W are now args.
4887 Return void, not bool. All callers changed.
4888 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4889 Remove. All uses removed. This bug should be fixed now in a
4891 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4892 and record the child status change directly. This avoids the
4893 need to futz with the signal mask.
4894 (process_fatal_action): Move here from emacs.c.
4895 (emacs_sigaction_flags): New function, containing
4896 much of what used to be in emacs_sigaction_init.
4897 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4898 caught by emacs, to make races less likely.
4899 (deliver_process_signal): Rename from handle_on_main_thread.
4901 (BACKTRACE_LIMIT_MAX): Now at top level.
4902 (thread_backtrace_buffer, threadback_backtrace_pointers):
4904 (deliver_thread_signal, deliver_fatal_thread_signal):
4905 New functions, for more-accurate delivery of thread-specific signals.
4906 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4907 (deliver_arith_signal): Handle in this thread, not
4908 in the main thread, since it's triggered by this thread.
4909 (maybe_fatal_sig): New function.
4910 (init_signals): New arg DUMPING so that we can be more accurate
4911 about whether we're dumping. Caller changed.
4912 Treat thread-specific signals differently from process-general signals.
4913 Block all signals while handling fatal error; that's safer.
4914 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4916 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4917 Ignore SIGPIPE unless batch.
4918 (emacs_backtrace): Output backtrace for the appropriate thread,
4919 which is not necessarily the main thread.
4920 * syssignal.h: Include <stdbool.h>.
4921 (emacs_raise): New macro.
4922 * xterm.c (x_connection_signal): Remove; no longer needed
4923 now that we use sigaction.
4924 (x_connection_closed): No need to mess with sigmask now.
4925 (x_initialize): No need to reset SIGPIPE handler here, since
4926 init_signals does this for us now.
4928 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4930 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4931 background rect may be larger (Bug#12245).
4933 2012-09-23 Chong Yidong <cyd@gnu.org>
4935 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4937 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4939 * .gdbinit: Just stop at fatal_error_backtrace.
4940 See Stefan Monnier's request in
4941 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4942 Remove no-longer-used query of system type.
4944 2012-09-22 Chong Yidong <cyd@gnu.org>
4946 * search.c (Freplace_match): Doc fix (Bug#12325).
4948 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4950 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4951 (Fline_end_position): Doc fix.
4953 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).

4957 * dispextern.h (struct image_type): Add new slot, storing a type
4958 initialization function.
4960 * image.c (define_image_type): Call the image initializer function
4961 if it is defined. Arguments and return value changed.
4962 (valid_image_p, make_image): Callers changed.
4963 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4964 (gif_type, imagemagick_type, svg_type, gs_type):
4965 Add initialization functions.
4966 (Finit_image_library): Call lookup_image_type.
4967 (CHECK_LIB_AVAILABLE): Macro deleted.
4968 (lookup_image_type): Call define_image_type here, rather than via
4969 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4970 (syms_of_image): Move define_image_type calls for xbm_type and
4971 pbm_type to lookup_image_type.
4973 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4975 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4976 'idle_timers' from here ...
4977 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4978 lists, to avoid infloops when the timer does something stupid,
4979 like reinvoke itself with the same or smaller time-out.
4982 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4984 * window.c (Fsplit_window_internal): Handle only Qt value of
4985 Vwindow_combination_limit separately.
4986 (Qtemp_buffer_resize): New symbol.
4987 (Vwindow_combination_limit): New default value.
4990 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4992 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4993 the new overlay string. (Bug#10159)
4995 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4997 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4998 or that fprintf is async-signal-safe. POSIX doesn't require
5001 2012-09-22 Chong Yidong <cyd@gnu.org>
5003 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5006 2012-09-22 Kenichi Handa <handa@gnu.org>
5008 * composite.c (composition_reseat_it): Handle the case that a
5009 grapheme cluster is not covered by a single font (Bug#12352).
5011 2012-09-21 Chong Yidong <cyd@gnu.org>
5013 * image.c (define_image_type): Avoid adding duplicate types to
5014 image_types (Bug#12463). Suggested by Jörg Walter.
5016 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5018 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5019 (print_load_command_name): Add case LC_DATA_IN_CODE.
5020 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5022 2012-09-21 Glenn Morris <rgm@gnu.org>
5024 * eval.c (Frun_hook_with_args_until_success)
5025 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5027 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5029 * fileio.c (Ffile_selinux_context): Only call freecon when
5030 lgetfilecon succeeded.
5031 (Fset_file_selinux_context): Likewise. (Bug#12444)
5033 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5035 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5036 reordering, locate the cursor by calling set_cursor_from_row; if
5037 that fails, clear the desired glyph matrix before returning a
5038 failure indication to the caller. Fixes leaving garbled display
5039 when fast scrolling with a down-key. (Bug#12403)
5040 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5041 scrolling through multibyte text.
5043 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5045 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5046 calling mark_vectorlike since that's the one that marks the window.
5047 (mark_discard_killed_buffers): Mark the final cdr.
5048 * window.h (struct window): Move prev/next_buffers to the
5049 non-standard fields.
5050 * window.c (make_window): Initialize prev/next_buffers manually.
5052 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5054 Omit unused arg EXPECTED from socket hooks.

5059 * w32term.c (w32_read_socket):
5060 * xterm.c (XTread_socket):
5061 Omit unused arg EXPECTED. All callers changed.
5062 (store_user_signal_events): Return void, not int, since callers no
5063 longer care about the return value. All uses changed.
5065 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5067 * w32gui.h (XParseGeometry): Do not declare.
5069 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5071 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5072 Ignore 'expected'. See Eli Zaretskii in
5073 <http://bugs.gnu.org/12471#8> (last line).
5075 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5076 (XParseGeometry): Now static. Substitute extremal values for
5077 values that are out of range.
5079 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5081 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5083 * nsfns.m (XParseGeometry): Remove.
5084 (Fx_create_frame): Call x_set_offset to correctly interpret
5085 top_pos in geometry.
5087 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5088 (Fx_parse_geometry): If there is a space in string, call
5089 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5091 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5093 * search.c (scan_buffer): Use character positions in calls to
5094 region_cache_forward and region_cache_backward, not byte
5095 positions. (Bug#12196)
5097 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5098 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5100 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5101 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5102 emacs_blocked_malloc, now deleted.
5104 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5106 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5107 The workaround was for improving performance on Solaris 2.4, but
5108 is getting in the way now. Emacs will still work if someone is
5109 still running Solaris 2.4 in a museum somewhere; Sun dropped
5110 support for Solaris 2.4 in 2003.
5111 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5112 * process.c (create_process) [HAVE_WORKING_VFORK]:
5113 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5114 since Emacs no longer uses vfork on that platform.
5116 2012-09-17 Glenn Morris <rgm@gnu.org>
5118 * emacs.c: Use COPYRIGHT.
5120 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5122 Remove configure's --without-sync-input option (Bug#12450).
5123 When auditing signal-handling in preparation for cleaning it up,
5124 I found that SYNC_INPUT has race conditions and would be a real
5125 pain to fix. Since it's an undocumented and deprecated
5126 configure-time option, now seems like a good time to remove it.
5127 Also see <http://bugs.gnu.org/11080#16>.
5128 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5129 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5130 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:

5137 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5138 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5139 Remove. All uses removed.
5140 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5141 implementation, one that depends on whether the new macro
5142 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5144 * atimer.c (run_timers, handle_alarm_signal):
5145 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5146 (handle_async_input, process_pending_signals)

5156 * eval.c (handling_signal): Remove. All uses removed.
5157 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5158 All uses replaced with the SYNC_INPUT version.
5159 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5161 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5164 * font.c (Ffont_shape_gstring): Remove unused local.
5166 2012-09-16 Glenn Morris <rgm@gnu.org>
5168 * Makefile.in (clean): No longer run nextstep's clean.
5170 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5172 (ns-app): Move here from ns.mk, and simplify.
5173 (clean): Simplify nextstep entry.
5174 * ns.mk: Remove file.
5176 2012-09-17 Kenichi Handa <handa@gnu.org>
5178 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5179 not covert the last few charactes.
5181 2012-09-16 Kenichi Handa <handa@gnu.org>
5183 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5184 here, but just check the validity of glyphs in the glyph-string.
5186 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5188 * window.c (Fwindow_parameter, Fset_window_parameter):

5193 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5194 to ns_term_init to avoid memory leak.
5196 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5197 explicit retain/release.

5201 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5203 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5204 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5205 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5206 the Microsoft problem in a different way, by altering ../nt/config.nt.
5208 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5223 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5224 by lisp.h. This completes removal of setjmp.h inclusion
5225 erroneously announced in the previous commit. (Bug#12446)
5227 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5230 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5231 not defined as a macro. The latter happens on MS-Windows.
5234 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5236 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5237 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5238 Some instances of '#include <setjmp.h>' removed, if the
5239 only reason for the instance was because "lisp.h" was included.
5240 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5241 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5242 and _longjmp with the new symbols. Emacs already uses _setjmp if
5243 available, so this change affects only POSIXish hosts that have
5244 sigsetjmp but not _setjmp, such as some versions of Solaris and
5245 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5246 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5247 (png_load_body) [HAVE_PNG]:
5248 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5249 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5250 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5251 since PNG requires jmp_buf. This is the only exception to the
5252 general rule that we now use sys_setjmp and sys_longjmp.
5253 This exception is OK since this code does not change the signal
5254 mask or longjmp out of a signal handler.
5256 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5258 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5259 Include "syssignal.h", for 'main_thread'.
5261 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5263 Avoid out-of-range marker position (Bug#12426).
5264 * insdel.c (replace_range, replace_range_2):
5265 Adjust markers before overlays, as suggested by comments.
5266 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5267 Remove redundant check before calling offset_intervals.
5269 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5271 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5272 current buffer (Bug#12387).
5274 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5276 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5278 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5280 Use a more backwards-compatible timer format (Bug#12430).
5281 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5282 vector element, not from the 4th, since PSECS is now at the end.
5283 (Fcurrent_idle_time): Doc fix.
5285 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5287 Function to mark objects and remove killed buffers at once.
5288 * alloc.c (discard_killed_buffers): Rename to ...
5289 (mark_discard_killed buffers) ... new name. Add marking
5290 of remaining objects. Fix comment. Adjust users.
5291 (mark_object): Do not touch frame buffer lists here.
5292 * frame.c (delete_frame): Reset frame buffer lists here.
5294 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5296 Better workaround for GNOME bug when --enable-gcc-warnings.
5297 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5298 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5299 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5301 Simplify SIGIO usage (Bug#12408).
5302 The code that dealt with SIGIO was crufty and confusing, e.g., it
5303 played tricks like "#undef SIGIO" but these tricks were not used
5304 consistently. Simplify mostly by not #undeffing standard symbols,
5305 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5306 or not as we please) rather than "defined SIGIO" (standard symbol
5307 that we probably shouldn't #undef).
5308 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5309 Modules that need it can include it.
5310 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5311 * dispextern.h (ignore_sigio): New decl.
5312 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5313 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5314 * emacs.c (shut_down_emacs):
5315 * keyboard.c (kbd_buffer_store_event_hold):
5316 Use ignore_sigio rather than invoking 'signal' directly.
5317 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5319 (FIONREAD, SIGIO): Do not #undef.
5320 (tty_read_avail_input): Use #error rather than a syntax error.
5321 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5322 for I_PIPE, used by SETUP_SLAVE_PTY.
5323 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5324 * sysdep.c (croak): Remove; no longer needed. This bit of
5325 temporary code, with Fred N. Fish's comment that it's temporary,
5326 has been in Emacs since at least 1992!
5327 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5328 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5329 * syssignal.h (croak): Remove decl.
5330 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5331 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5332 now that we're termios-only.
5333 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5334 * term.c (dissociate_if_controlling_tty): Use #error rather than
5337 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5338 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5339 to work around GNOME bug 683906.
5340 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5341 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5342 This works around GCC bug 54561.
5344 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5346 More fixes for 'volatile' and setjmp/longjmp.
5347 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5348 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5349 (png_load_body) [HAVE_PNG]:
5350 (jpeg_load_body) [HAVE_JPEG]:
5351 New function, with most of the old parent function's body.
5352 (png_load) [HAVE_PNG]:
5353 (jpeg_load) [HAVE_JPEG]:
5354 Invoke the new function, to avoid longjmp munging our locals.
5355 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5356 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5357 longjmp is passed 2, as the C standard doesn't guarantee this.
5358 Instead, store the failure code into mgr->failure_code.
5360 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5362 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5363 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5364 (syms_of_keyboard): Remove support for unread-command-char.
5366 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5368 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5369 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5370 violation. (Bug#12426)
5372 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5374 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5376 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5378 * eval.c: Add `inhibit-debugger'.
5379 (Qinhibit_debugger): New symbol.
5380 (call_debugger): Bind it instead of Qdebug_on_error.
5381 (maybe_call_debugger): Test Vinhibit_debugger.
5382 (syms_of_eval): Define inhibit-debugger.
5383 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5384 (syms_of_xdisp): Remove inhibit-debug-on-message.
5386 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5388 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5389 If a nonvolatile local variable is written before a _longjmp to
5390 the frame containing the variable, and is read after the _longjmp,
5391 the value read is indeterminate. Some local variables of type
5392 'struct handler' and 'struct catchtag' are used in this way, so
5393 mark each of their slots as volatile if the slot can be set before
5394 _longjmp and read afterwards.
5395 * lisp.h (struct handler): var and chosen_clause are now volatile.
5396 (struct catchtag): val, next, and pdlcount are now volatile.
5398 * bidi.c (bidi_push_it, bidi_pop_it):
5399 * fns.c (copy_hash_table):
5400 * image.c (define_image_type):
5401 * keyboard.c (kbd_buffer_store_event_hold):
5402 * process.c (Fprocess_send_eof):
5403 * xfaces.c (x_create_gc) [HAVE_NS]:
5404 * xgselect.c (xg_select):
5405 Prefer assignment to memcpy when either will do.
5407 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5408 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5409 time an item is removed. No need to mark this function 'inline';
5410 the compiler knows better than we do.
5412 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5414 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5415 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5416 to change_frame_size (Bug#12388).
5417 (windowDidResize:): Pass YES to updateFrameSize.
5419 * nsterm.h: Add delay parameter to updateFrameSize.
5421 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5423 Discard killed buffers from deleted window and frame objects.
5424 This reduces an amount of references to killed buffers and
5425 helps GC to reclaim them faster.
5426 * alloc.c (discard_killed_buffers): New function.
5427 (mark_object): Use it for deleted windows and frames.
5428 (mark_object): If symbol's value is set up for a killed buffer
5429 or deleted frame, restore its global binding.
5430 * data.c (swap_in_global_binding): Add GC notice.
5431 (swap_in_symval_forwarding): Use convenient set_blv_where.
5432 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5433 * window.h: ... to here.
5435 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5437 Convenient macro to check whether the buffer is live.
5438 * buffer.h (BUFFER_LIVE_P): New macro.
5439 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5440 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5442 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5444 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5445 composition cases (Bug#12364).
5447 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5448 overhang of succeeding glyphs overlapping box cursor.
5450 * w32term.c (x_draw_glyph_string): Likewise.
5452 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5454 Simplify, document, and port floating-point (Bug#12381).
5455 The porting part of this patch fixes bugs on non-IEEE platforms
5456 with frexp, ldexp, logb.
5457 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5459 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5460 support, by removing commented-out code and briefly listing the
5461 C89 functions excluded. The commented-out stuff was confusing
5462 maintenance, e.g., we thought we needed cbrt but it was commented out.
5463 (logb): Remove decl; no longer needed.
5464 (isfinite): New macro, if not already supplied.
5465 (isnan): Don't replace any existing macro.
5466 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5467 are present on all C89 platforms.
5468 (Ffrexp): Do not special-case zero, as frexp does the right thing
5470 (Flogb): Do not use logb, as it doesn't have the desired meaning
5471 on hosts that use non-base-2 floating point. Instead, stick with
5472 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5473 frexp, to avoid getting an unspecified result.
5475 * xdisp.c (Qinhibit_debug_on_message): Now static.
5477 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5479 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5480 NSBezierPath (Bug#12131).
5482 2012-09-10 Chong Yidong <cyd@gnu.org>
5484 * fns.c (Fdelq, Fdelete): Doc fix.
5486 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5488 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5489 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5491 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5493 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5494 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5497 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5499 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5500 left fringe if the window has a left margin. This avoids leaving
5501 traces of the cursor because its leftmost pixel is not drawn over.
5503 * dispnew.c (update_window_line): When the left margin area of a
5504 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5505 that screen line. (Bug#12277)
5507 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5509 Assume C89 or later for math functions (Bug#12381).
5510 This simplifies the code, and makes it a bit smaller and faster,
5511 and (most important) makes it easier to clean up signal handling
5512 since we can stop worring about floating-point exceptions in
5513 library code. That was a problem before C89, but the problem
5514 went away many years ago on all practical Emacs targets.
5515 * data.c, image.c, lread.c, print.c:
5516 Don't include <math.h>; no longer needed.
5517 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5518 might be autoconfigured, as that never happens.
5520 * doprnt.c (DBL_MAX_10_EXP):
5521 * print.c (DBL_DIG):
5522 Remove. C89 or later always defines these.
5523 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5524 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5525 (arith_error, domain_error, domain_error2):
5526 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5527 no longer needed -- we simply return what C returns. All uses removed.
5528 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5530 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5531 Remove. All uses expanded, as these macros are no longer used
5532 more than once and are now more trouble than they're worth.
5533 (Ftan): Use tan, not sin / cos.
5534 (Flogb): Assume C89 frexp.
5535 (fmod_float): Assume C89 fmod.
5536 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5537 (init_floatfns): Remove. All uses removed.
5539 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5541 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5542 compositeToPoint for OSX < 10.6 (Bug#12390).
5544 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5546 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5547 This produces more-accurate results.
5549 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5551 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5552 changes (Bug#12088).
5554 2012-09-08 Chong Yidong <cyd@gnu.org>
5556 * syntax.c (Fstring_to_syntax): Doc fix.
5558 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5560 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5561 in the internal border.
5562 (x_set_window_size): Remove static variables and their usage.
5563 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5564 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5565 Remove fringe/internal border adjustment (Bug#11052).
5566 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5567 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5568 (ns_fix_rect_ibw): Remove.
5569 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5570 (ns_dumpglyphs_box_or_relief): Ditto.
5571 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5573 (ns_dumpglyphs_image): Ditto.
5574 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5576 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5577 their usage. Add fringe_extended_p and its use as in other terms.
5578 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5579 scroll bar was removed.
5580 (updateFrameSize): New function.
5581 (windowDidResize): Move code to updateFrameSize and call it.
5583 * nsterm.h (EmacsView): Add updateFrameSize.
5585 2012-09-07 Chong Yidong <cyd@gnu.org>
5587 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5589 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5591 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5593 More signal-handler cleanup (Bug#12327).
5594 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5595 Problem introduced when merging patches. Noted by Eli Zaretskii in
5596 <http://bugs.gnu.org/12327#67>.
5597 * floatfns.c: Comment fix.
5598 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5599 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5600 and anyway the declaration is harmless even if SIGDANGER is not defined.
5601 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5602 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5603 source files not surprisingly expected syssignal.h to define, or
5604 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5605 Include <sys/ioctl.h>, for FIONREAD.
5606 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5607 This eliminates a problem whereby other files mysteriously had
5608 to include "syssignal.h" before including "systty.h" if they
5609 wanted to use "#ifdef SIGIO".
5611 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5613 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5615 * w32.c (sigemptyset): Empty the set.
5616 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5618 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5620 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5622 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5623 (mark_object): Likewise for frame objects.
5625 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5627 * syssignal.h (handle_on_main_thread): Always declare,
5628 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5629 This ports to platforms without HAVE_PTHREAD.
5631 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5633 Signal-handler cleanup (Bug#12327).
5634 Emacs's signal handlers were written in the old 4.2BSD style with
5635 sigblock and sigmask and so forth, and this led to some
5636 inefficiencies and confusion. Rewrite these to use
5637 pthread_sigmask etc. without copying signal sets around. Also,
5638 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5639 'signal', and instead use functions that do not attempt to take
5640 over the system name space. This patch causes Emacs's text
5641 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5642 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5643 Do not include <signal.h> or "syssignal.h", as these
5644 modules do not use signals.
5645 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5646 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5647 Do not include <signal.h>, as "syssignal.h" does that for us now.
5648 * atimer.c (sigmask_atimers): New function.
5649 (block_atimers, unblock_atimers): New functions,
5650 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5652 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5653 no longer needed here.
5654 * emacs.c (main): Inspect existing signal handler with sigaction,
5655 so that there's no need to block and unblock SIGHUP.
5656 * sysdep.c (struct save_signal): New member 'action', replacing
5657 old member 'handler'.
5658 (save_signal_handlers, restore_signal_handlers):
5659 Use sigaction instead of 'signal' to save and restore.
5660 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5661 New function. All users of 'signal' modified to use set_sighandler
5662 if they're writeonly, and to use sys_signal if they're read+write.
5663 (emacs_sigaction_init, forwarded_signal): New functions.
5664 (sys_signal): Remove. All uses replaced by calls to sigaction
5665 and emacs_sigaction_init, or by direct calls to 'signal'.
5666 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5667 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5668 all uses replaced by pthread_sigmask etc. calls.
5669 * syssignal.h: Include <signal.h>.
5670 (emacs_sigaction_init, forwarded_signal): New decls.
5671 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5672 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5673 (sigmask, sys_sigmask): Remove; no longer needed.
5674 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5675 (sigblock, sigunblock, sigfree):
5676 (sigsetmask) [!defined sigsetmask]:
5677 Remove. All uses replaced by pthread_sigmask.
5678 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5679 no longer need to be replaced, and its typical old uses
5680 are now done via emacs_sigaction_init and sigaction.
5681 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5682 (sys_sigdel): Remove; unused.
5683 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5685 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5687 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5688 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5690 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5692 Explicitly mark buffer_defaults and buffer_local_symbols.
5693 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5694 mark_local_symbols here.
5695 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5696 since special buffers aren't marked here any more.
5697 (allocate_buffer): Chain new buffer with all_buffers here...
5698 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5700 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5701 (syms_of_buffer): Remove staticpro of the above.
5702 (init_buffer_once): Set names for buffer_defaults and
5703 buffer_local_symbols.
5705 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5707 Use bool for booleans in font-related modules.
5708 * font.c (font_intern_prop, font_style_to_value)
5709 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5710 (generate_otf_features, font_check_otf_features, font_check_otf)
5711 (font_match_p, font_list_entities, font_at):
5712 * fontset.c (fontset_id_valid_p, reorder_font_vector
5713 (fontset_find_font, Fset_fontset_font)
5714 (face_suitable_for_char_p) [0]:
5715 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5716 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5717 (m17n_flt_initialized, ftfont_shape_by_flt):
5718 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5719 * nsfont.m (nsfont_draw):
5720 * w32font.c (w32font_draw):
5721 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5722 Use bool for booleans.
5723 * font.h: Adjust to above API changes.
5724 (struct font, struct font_driver, struct font_driver_list):
5725 Use bool for booleans.
5726 (struct font): Remove useless member encoding_type.
5728 * fontset.c, xftfont.c: Omit unnecessary static decls.
5730 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5732 * alloc.c (mark_object): Revert window marking code
5733 since it's unsafe for the Fset_window_configuration.
5735 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5737 Fix race conditions with signal handlers and errno (Bug#12327).
5738 Be more systematic about preserving errno whenever a signal
5739 handler returns, even if it's not in the main thread. Do this by
5740 renaming signal handlers to distinguish between signal delivery
5741 and signal handling. All uses changed.
5742 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5743 * data.c (deliver_arith_signal): Rename from arith_error.
5744 * dispnew.c (deliver_window_change_signal): Rename from
5745 window_change_signal.
5746 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5747 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5748 * keyboard.c (deliver_input_available_signal): Rename from
5749 input_available_signal.
5750 (deliver_user_signal): Rename from handle_user_signal.
5751 (deliver_interrupt_signal): Rename from interrupt_signal.
5752 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5753 (deliver_child_signal): Rename from sigchld_handler.
5754 * atimer.c (handle_alarm_signal):
5755 * data.c (handle_arith_signal):
5756 * dispnew.c (handle_window_change_signal):
5757 * emacs.c (handle_fatal_signal, handle_danger_signal):
5758 * keyboard.c (handle_input_available_signal):
5759 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5760 * process.c (handle_pipe_signal, handle_child_signal):
5761 New functions, with the actual signal-handling code taken from the
5762 original respective signal handlers, sans the sporadic attempts to
5763 preserve errno, since that's now done by handle_on_main_thread.
5764 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5765 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5766 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5768 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5769 Move initialization of main_thread to sysdep.c's init_signals.
5770 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5771 our usage, and simplifies the mainline code.
5772 (record_child_status_change): New static function, as a helper
5773 for handle_child_signal, and with most of the old child handler's
5775 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5776 (handle_child_signal): Use the above.
5777 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5778 Moved here from emacs.c.
5779 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5780 code moved here from emacs.c's main function.
5781 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5782 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5783 This lets callers save and restore errno properly.
5785 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5787 Remove redundant or unused things here and there.
5788 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5789 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5790 * editfns.c (Fcompare_buffer_substrings): Likewise.
5791 * frame.h (struct terminal, struct font_driver_list):
5792 Remove redundant declarations.
5793 * window.h (Qleft, Qright): Likewise.
5795 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5797 Do not mark objects from deleted buffers, windows and frames.
5798 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5799 (mark_object): Likewise for windows and frames.
5801 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5803 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5804 buffer_defaults and buffer_local_symbols as valid objects.
5805 Return special value to denote them.
5807 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5809 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5810 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5811 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5812 (file_name_absolute_p, Fsubstitute_in_file_name):
5813 (check_executable, check_writable, Ffile_accessible_directory_p)
5814 (Fset_file_selinux_context, Fdefault_file_modes)
5815 (Finsert_file_contents, choose_write_coding_system)
5816 (Fwrite_region, build_annotations, a_write, e_write)
5818 * filelock.c (boot_time_initialized, get_boot_time)
5819 (get_boot_time_1, lock_file_1, within_one_second):
5820 * floatfns.c (in_float):
5821 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5822 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5823 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5824 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5825 * window.c (compare_window_configurations):
5826 Use bool for booleans.
5827 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5828 (Fdefault_file_modes): Now mode_t, not int, for modes.
5829 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5830 (internal_delete_file): Now returns void, not a (boolean) int,
5831 since nobody was looking at the return value.
5832 * lisp.h, window.h: Adjust to above API changes.
5834 * xdisp.c (set_message): Simplify and reindent last change.
5836 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5838 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5840 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5842 * eval.c (call_debugger): Make the function non-static so that we
5843 can call it from set_message.
5845 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5846 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5848 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5850 Give more-useful info on a fatal error (Bug#12328).
5851 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5852 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5853 of doing the work ourselves.
5854 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5855 do most of the work.
5856 (fatal_error_backtrace): New function, taken from the guts
5857 of the old fatal_error_signal, but with a new option to output
5859 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5860 info about the signal than just its number.
5861 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5862 * sysdep.c: Include <execinfo.h>
5863 (emacs_backtrace): New function, taken partly from the previous
5864 code of the 'die' function.
5865 (emacs_abort): Call fatal_error_backtrace rather than abort.
5867 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5869 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5870 eager (load-time) macro-expansion.
5871 * lisp.mk (lisp): Add macroexp.
5873 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5875 Simplify redefinition of 'abort' (Bug#12316).
5876 Do not try to redefine the 'abort' function. Instead, redo
5877 the code so that it calls 'emacs_abort' rather than 'abort'.
5878 This removes the need for the NO_ABORT configure-time macro
5879 and makes it easier to change the abort code to do a backtrace.
5880 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5881 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5882 Remove; sysdep.c's emacs_abort now takes its place.
5883 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5884 'abort' changed to use 'emacs_abort'.
5885 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5886 (abort) [!defined abort]: Rename to ...
5887 (emacs_abort): ... new name.
5888 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5889 the place of the old 'abort' in emacs.c.
5890 * w32.c, w32fns.c (abort): Do not #undef.
5891 * w32.c (emacs_abort): Rename from w32_abort.
5893 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5895 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5896 offsets[j].dv, since the y axis of the screen coordinates points
5897 down, while the y axis of the font definition coordinates points
5898 up. This fixes display of Arabic diacritics such as KASRA and
5899 KASRATAN. (Bug#11860)
5901 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5903 Be more systematic about _setjmp vs setjmp.
5904 * alloc.c (test_setjmp, mark_stack):
5905 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5906 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5907 (png_load, my_error_exit, jpeg_load):
5908 * process.c (send_process_trap, send_process):
5909 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5910 The underscored versions are up to 30x faster on some hosts.
5911 Formerly, the code used setjmp+longjmp sometimes and
5912 _setjmp+_longjmp at other times, with no particular reason to
5913 prefer setjmp+longjmp.
5915 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5917 Fix minor problem found by static checking.
5918 * buffer.c (Fdelete_all_overlays): Return nil.
5920 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5922 * buffer.c (Fdelete_all_overlays): New function.
5924 2012-09-03 Chong Yidong <cyd@gnu.org>
5926 * gtkutil.c: Add extern decl for Qxft.
5928 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5930 * emacs.c, eval.c: Use bool for boolean.
5931 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5932 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5933 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5934 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5935 (main, decode_env_path, Fdaemon_initialized):

5950 * msdos.c (fatal_error_in_progress): ... from here.
5951 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5953 (redisplay_internal, unwind_redisplay): Simply clear
5954 REDISPLAYING_P when unwinding, instead of saving its previous,
5955 always-false value and then restoring it.
5957 Clean up some extern decls.
5958 Mostly, this hoists extern decls out of .c files and into .h files.
5959 That way, we're more likely to catch errors if the interfaces change.

6045 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6046 more than one grapheme cluster passed to the shaper: compute the
6047 offset adjustment values separately for each cluster. (Bug#11860)
6049 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6050 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6051 about implicit conversions from integer to pointer.
6053 2012-09-01 Daniel Colascione <dancol@dancol.org>
6055 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

6109 window system declarations.
6111 * frame.h: Move common functions here: set_frame_menubar,
6112 x_set_window_size, x_sync, x_get_focus_frame,
6113 x_set_mouse_position, x_set_mouse_pixel_position,
6114 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6145 * term.c (mark_ttys): Remove.
6146 (init_tty): Safely initialize 'top_frame' slot with Qnil.

6171 for GCC 4.7.1 x86-64.
6173 2012-08-30 Glenn Morris <rgm@gnu.org>
6175 * lread.c (init_lread): For out-of-tree builds, only add the
6176 source directory's site-lisp dir to the load-path if it exists,
6177 consistent with in-tree builds. (Bug#12302)
6179 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6198 Handle click on close button as quit.
6200 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6201 Add window_closed and button_values. Add void as return value for
6202 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6203 Add process_dialog as new member.
6205 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6207 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

6385 * data.c (Qinterval): Remove; unused.
6386 (syms_of_data): Do not define 'interval'.
6387 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6388 * window.h (decode_valid_window):
6391 * character.c, charset.c, chartab.c: Use bool for booleans.
6392 * character.c (lisp_string_width, string_count_byte8)
6393 (string_escape_byte8):
6394 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6395 (load_charset_map_from_file, map_charset_chars)
6396 (Fdefine_charset_internal, define_charset_internal)
6397 (Fdeclare_equiv_charset, find_charsets_in_text)
6398 (Ffind_charset_region, char_charset, Fiso_charset):
6399 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6400 (sub_char_table_set, sub_char_table_set_range)
6401 (char_table_set_range, optimize_sub_char_table)
6402 (map_sub_char_table):
6403 Use bool for boolean.
6404 * character.c (str_to_unibyte): Omit last boolean argument; it was
6405 always 0. All callers changed.
6406 * character.h, charset.h: Adjust to match previous changes.
6407 * character.h (char_printable_p): Remove decl of nonexistent function.
6408 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6409 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6410 are all boolean, so make them single-bit bitfields.
6412 * lisp.h (ASET): Remove attempt to detect side effects.
6413 It was meant to be temporary and it often doesn't work,
6414 because when IDX has side effects the behavior of IDX==IDX
6415 is undefined. See Stefan Monnier in
6416 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6418 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6420 * lisp.h (functionp): New function (extracted from Ffunctionp).
6421 (FUNCTIONP): Use it.
6422 * eval.c (Ffunctionp): Use it.
6424 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6426 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6427 as that's faster and simpler than static storage. Don't bother
6428 with the g_main_context_query overhead if g_main_context_pending
6429 says no events are pending.
6430 (gfds, gfds_size): Remove these static vars.
6431 (xgselect_initialize): Remove; no longer needed.
6432 All uses and decls removed.
6434 * emacs.c (fatal_error_signal_hook): Remove.
6435 All uses removed. This leftover from old code was always 0.
6437 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6438 * casefiddle.c (casify_object, casify_region):
6439 * casetab.c (set_case_table):
6440 * category.c, category.h (word_boundary_p):
6441 * category.h (CHAR_HAS_CATEGORY):
6442 Use bool for booleans, instead of int.
6444 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6446 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6448 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6450 On assertion failure, print backtrace if available.
6451 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6452 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6453 * Makefile.in (LIB_EXECINFO): New macro.
6456 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6457 * bytecode.c (exec_byte_code):
6458 * callint.c (check_mark, Fcall_interactively):
6459 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6460 (getenv_internal, sync_process_alive, call_process_exited):
6461 * lisp.h (USE_SAFE_ALLOCA):
6462 Use bool for booleans, instead of int.
6463 * lisp.h, process.h: Adjust prototypes to match above changes.
6464 * callint.c (Fcall_interactively): Don't assume the mark's
6465 offset fits in 'int'.
6467 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6469 * buffer.c, buffer.h: Use bool for boolean.
6470 * buffer.c (reset_buffer_local_variables)
6471 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6472 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6473 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6474 (overlay_touches_p, overlay_strings, Foverlay_put)
6475 (report_overlay_modification, call_overlay_mod_hooks):
6476 (mmap_enlarge, mmap_set_vars):
6477 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6478 Use bool for booleans, instead of int.
6479 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6480 since the 1-or-0 return value is always ignored anyway.
6481 (mmap_initialized_p):
6482 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6483 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6485 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6487 * bidi.c: Use bool for boolean.
6488 This is a bit more readable, and makes the text segment of bidi.o
6489 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6490 Presumably it's faster too.
6491 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6493 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6494 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6495 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6496 (bidi_explicit_dir_char, bidi_level_of_next_char)
6497 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6498 Use bool for booleans, instead of int.
6499 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6500 (bidi_unshelve_cache): Adjust decls to match code.
6502 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6504 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6507 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6509 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6510 * atimer.h: Include <stdbool.h>.
6512 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6514 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6515 compile time tests instead of run time tests on systems that do
6517 (FRAME_MAC_P): Remove leftover from deleted code.
6518 * frame.c (syms_of_frame): Remove leftover from deleted code.
6520 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6522 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6524 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6526 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6527 Otherwise, the compiler complains about (A?B:C) where B is void
6528 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6529 (fontset_add): Return void, for FONTSET_ADD.
6531 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6533 * alloc.c: Use bool for booleans.
6534 (gc_in_progress, abort_on_gc)
6535 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6536 (dont_register_blocks) [GC_MALLOC_CHECK]:
6537 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6538 (check_string_bytes, make_specified_string, memory_full)
6539 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6540 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6541 (mark_stack, valid_pointer_p, make_pure_string)
6542 (Fgarbage_collect, survives_gc_p, gc_sweep):
6543 Use bool for booleans, instead of int.
6544 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6545 Remove unused local.
6546 * alloc.c (PURE_POINTER_P):
6547 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6548 * editfns.c (Fformat):
6549 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6551 * fns.c (sweep_weak_table):
6552 * lisp.h (suppress_checking, push_message, survives_gc_p)
6553 (make_pure_string, gc_in_progress, abort_on_gc):
6554 * lread.c (readchar, read1):
6555 * print.c (Fprin1_to_string):
6556 * xdisp.c (push_message):
6557 Use bool for booleans affected directly or indirectly by
6560 Make recently-introduced setters macros.
6561 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6562 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6563 (set_fontset_default, set_fontset_fallback): Rename from their
6564 upper-case counterparts, and make them functions rather than macros.
6565 This is more consistent with the other recently-introduced setters.
6566 These don't need to be inline, since they're local.
6568 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6570 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6571 the loop (Bug#12247).
6573 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6575 * lisp.h (vcopy): Use memcpy rather than our own loop.
6576 This fixes a performance regression introduced by the recent
6577 addition of vcopy. This means 'vcopy' will need to be modified
6578 for a copying collector, but that's OK. Also, tighten the
6579 checking in the assertion.
6581 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6583 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6584 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6585 non-base glyph for the width of the base character, according to
6586 what x_draw_composite_glyph_string_foreground expects.
6587 Generate WADJUST value according to composition_gstring_width's
6588 expectations, to produce correct width of the composed character.
6589 Reverse the sign of the DU offset produced by ScriptPlace.
6591 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6593 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6595 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6597 Avoid direct writes to contents member of struct Lisp_Vector.
6598 * lisp.h (vcopy): New function to copy data into vector.
6599 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6600 * fns.c (Ffillarray): Use ASET.
6601 * keyboard.c (timer_check_2): Use AREF and ASET.
6602 (append_tool_bar_item, Frecent_keys): Use vcopy.
6603 * lread.c (read_vector): Use ASET.
6604 * msdos.c (Frecent_doskeys): Use vcopy.
6605 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6606 (Finternal_merge_in_global_face): Use ASET and vcopy.
6607 * xfont.c (xfont_list_pattern): Likewise.
6609 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6611 * window.c (Fwindow_point): For the selected window always return
6612 the position of its buffer's point.
6613 (Fset_window_point): For the selected window always go in its
6614 buffer to the specified position.
6616 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6618 Setter macros for fontsets.
6619 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6620 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6621 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6624 2012-08-20 Glenn Morris <rgm@gnu.org>
6626 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6627 Don't assume that `ln -f' works.
6629 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6631 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6632 and later about non-assignments with no effect. See discussion at
6633 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6636 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6638 Inline setter functions for Lisp_Objects slots of struct specbinding.
6639 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6642 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6644 * window.c (select_window): Always make selected window's buffer
6647 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6649 Use AREF and ASET for docstrings of category tables.
6650 * category.h (CATEGORY_DOCSTRING): Use AREF.
6651 (SET_CATEGORY_DOCSTRING): Use ASET.
6652 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6654 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6656 Inline setter functions for hash table members.
6657 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6658 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6659 (set_hash_key_and_value, set_hash_index, set_hash_next)
6660 (set_hash_hash): New functions.
6661 * charset.c, fns.c: Adjust users.
6663 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6665 Inline getter and setter functions for per-buffer values.
6666 * buffer.h (per_buffer_default, set_per_buffer_default)
6667 (per_buffer_value, set_per_buffer_value): New functions.
6668 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6669 * buffer.c, data.c: Adjust users.
6671 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6673 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6675 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6677 Rely on <config.h> + <unistd.h> to declare 'environ',
6678 as gnulib does this if the system doesn't.
6679 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6680 Remove declaration. MS-Windows declares it on stdlib.h which is
6681 included by conf_post.h.
6682 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6683 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6684 * vm-limit.c: Include <unistd.h>, for 'environ'.
6686 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6687 (start_of_data): Remove decl; mem-limits.h provides it.
6689 * xdisp.c (handle_invisible_prop): Make it a bit faster
6690 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6692 2012-08-19 Chong Yidong <cyd@gnu.org>
6694 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6697 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6699 * .gdbinit: Use call instead of set when calling a function in the
6702 * data.c (set_internal): Don't use set_blv_found.
6703 (Fkill_local_variable): Likewise.
6705 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6707 * nsfont.m (ns_ascii_average_width): Ensure the string
6708 ascii_printable is initialized with a null-terminated character
6709 array. Otherwise, it can contain undesired extra characters.
6711 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6713 port new setting code to Sun C 5.8 2005/10/13
6714 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6715 Return void, not Lisp_Object. Otherwise, the compiler
6716 complains about (A?B:C) where B is void and C is Lisp_Object
6717 when compiling CHAR_TABLE_SET, due to the recent change to
6718 the API of sub_char_table_set_contents.
6720 2012-08-18 Chong Yidong <cyd@gnu.org>
6722 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6723 for the string case (Bug#3874).
6725 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6727 * buffer.h (BSET): Remove (Bug#12215).
6728 Replace all uses with calls to new setter functions.

6797 New setter functions.
6799 * termhooks.h (TSET): Remove (Bug#12215).
6800 Replace all uses with calls to new setter functions.
6801 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
6802 (TERMHOOKS_INLINE): New macro.
6803 (tset_charset_list, tset_selection_alist): New setter functions.
6804 * terminal.c (TERMHOOKS_INLINE):
6805 Define to EXTERN_INLINE, so that the corresponding functions
6806 are compiled into code.
6807 (tset_param_alist): New setter function.
6809 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
6811 * keyboard.h (KSET): Remove (Bug#12215).

7555 value of EMACSLOADPATH, as it is no longer needed.
7556 (check_windows_init_file): Now external, not static.

7562 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7607 * alloc.c (record_xmalloc): New function.
7608 * lisp.h (record_xmalloc): New decl.
7609 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7610 more like a function. This is because the pointer cast is not
7611 needed. All uses changed.
7612 * print.c (print_string, print_error_message): Avoid length recalc.
7614 Improve fix for macroexp crash with debugging (Bug#12118).
7615 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7616 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7617 not supposed to be invoked from the garbage collector.

7619 (gc_aset): New function, which is like ASET but can be
7620 used in the garbage collector.

7649 with addition of handling of symlinks and support for 'lstat'.
7650 If possible, get file's attributes and security information by
7651 handle, not by name. Produce S_IFLNK bit for symlinks, when
7652 called from 'lstat'.
7653 (stat, lstat): New functions, call 'stat_worker'.
7654 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7655 symlinks when the underlying filesystem supports them.
7657 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7659 Fix macroexp crash on Windows with debugging (Bug#12118).
7660 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7661 checking subscripts; problem introduced with the recent
7662 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7663 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7664 since it's used in non-static inline functions now.
7666 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7667 Don't assume buffer size fits in 'int'. Remove unused local.

8155 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8157 Improve GDB symbol export (Bug#12036).
8158 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8159 arms of an 'if', not using conditional expressions; otherwise GDB
8160 complains about the types in the unevaluated arm when the argument
8161 is an integer literal.
8162 (xgetint): Simplify expression.
8163 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8164 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8165 Zaretskii in <http://bugs.gnu.org/12036#13>.
8166 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8167 needed now that we have gdb_make_enums_visible.
8168 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8169 (enum enum_USE_LSB_TAG):
8170 New enum types, packaging up enums that need to be exported to GDB.
8172 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8174 Utility function to make a list from specified amount of objects.

8176 (listn): New prototype.
8177 * alloc.c (listn): New function.
8178 (Fmemory_use_count, syms_of_alloc): Use it.

8188 * xdisp.c (syms_of_xdisp): Likewise.
8189 * xfns.c (syms_of_xfns): Likewise.
8191 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8193 Fast save_excursion_save and save_excursion_restore.
8194 * lisp.h (struct Lisp_Excursion): New data type.
8195 (PVEC_EXCURSION): New pseudovector type.
8196 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8197 to deal with it. Adjust comments.
8198 (init_marker, attach_marker): New prototype.
8199 (unchain_marker): Adjust prototype.
8200 * marker.c (attach_marker): Change to global.

8204 (mark_object): Handle struct Lisp_Excursion.
8205 * editfns.c (save_excursion_save, save_excursion_restore):
8206 Reimplement to use struct Lisp_Excursion. Add comments.
8208 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8210 Fix export of symbols to GDB (Bug#12036).
8211 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8212 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8213 emacs.c, as this is a more-suitable home. Had this been done earlier
8214 the fix for 12036 would have avoided some of the problems noted in
8215 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8216 would have been more obvious.
8217 * emacs.c: Do not include <verify.h>; no longer needed.
8218 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8219 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8220 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8221 Remove; now done in lisp.h.
8222 * lisp.h (PUBLISH_TO_GDB): New macro.
8223 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8224 (DATA_SEG_BITS): Use it.
8225 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8226 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8227 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8228 not be usable in #if. This simplifies things.
8230 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8232 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8234 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8236 Simplify export of symbols to GDB (Bug#12036).
8237 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8238 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8239 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8240 Adjust to changes in lisp.h and emacs.c, by using
8241 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8242 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8243 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8244 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8245 instead of gdb_valbits.
8246 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8247 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8248 instead of gdb_array_mark_flag.
8249 (xboolvector): Get size from $->size, not $->header.size.
8250 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8251 (xreload, hook-run, hookpost-run): Remove.
8252 * emacs.c: Include <verify.h>.
8253 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8254 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8256 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8257 (gdb_USE_LSB_TAG): New enum constants.
8258 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8259 Also define these as enum constants, so they're visible to GDB.
8260 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8261 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8262 as constants, so they're visible to GDB.
8263 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8264 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8265 Now enum constants, not macros, so they're visible to GDB.
8266 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8267 more convenient now. All uses changed.
8268 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8269 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8271 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8276 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8278 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8279 add argument, tune behavior, and adjust all callers.
8281 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8283 Use typedef for EMACS_INT, EMACS_UINT.
8284 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8285 than macros. This simplifies debugging in the usual case, since
8286 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8287 and it allows expressions involving EMACS_INT casts.
8288 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8290 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8292 * nsterm.m (ns_read_socket): Return early if there is a modal

8298 that FOCUS-FRAME can be omitted.
8300 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8302 Adjust buffer text indirection counters at the end of Fkill_buffer.
8303 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8304 buffer is definitely dead. This should really fix an issue reported
8305 by Christoph Scholtes again. (Bug#12007).
8306 (init_buffer_once): Initialize indirection counters of
8307 buffer_defaults and buffer_local_symbols (for sanity and safety).
8309 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8311 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8312 and continuation glyphs on tooltip frames, leave them at zero.
8313 Avoids continued lines in tooltips. (Bug#11832)
8315 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

8327 it signals an error when a tooltip frame is being created.
8329 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8331 Cleanup miscellaneous objects allocation and initialization.

8340 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8342 Swap buffer text indirection counters in Fbuffer_swap_text.
8343 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8344 This avoids crash reported by Christoph Scholtes at
8345 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8347 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8349 * nsmenu.m (Popdown_data): New struct.
8350 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8352 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

8354 and autorelease them. Also autorelease img and matrix (Bug#12005).
8355 (dealloc): Remove (Bug#12005).
8357 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8359 Adjust consing_since_gc when objects are explicitly freed.
8360 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.

8372 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8374 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8375 as it's limited by the amount of memory, not by INT_MAX.
8377 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8379 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8380 in special-event-map. See the discussion at

8439 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8440 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8441 Adjust users accordingly.
8442 * font.h (font_open_by_name): Adjust prototype.
8444 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

8460 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8461 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8462 'for_each_per_buffer_object_at'.
8463 All uses changed. It's better to use upper-case for macros that
8464 cannot be implemented as functions, to give the reader a clue
8465 that they're special.
8467 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8469 * alloc.c (Fgarbage_collect): Tweak docstring.

8510 * intervals.c (merge_interval_right, merge_interval_left):
8511 Do not zero out this interval if it is absorbed by its children,
8512 as this interval's total length doesn't change in that case. See
8513 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8515 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8517 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8518 when invoking (make-bool-vector N t) and N is a positive
8519 multiple of 8 -- the last 8 bits were mistakenly cleared.
8521 Remove some struct layout assumptions in bool vectors.
8522 * alloc.c (bool_header_size): New constant.
8523 (header_size, word_size): Move earlier, as they're now used earlier.

8526 padding before the data member of a bool vector.
8527 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
8528 than doing the check by hand with an abort ().
8530 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8532 * eval.c (Fdefvar): Don't check constants since we only set the var if
8533 it's not yet defined anyway (bug#11904).
8535 * lisp.h (last_undo_boundary): Declare new var.
8536 * keyboard.c (command_loop_1): Set it.
8537 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8538 were auto-added by the command loop (bug#11774).
8540 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
8542 * w32font.c (Qsymbol): Remove local definition.

9036 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
9037 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

9040 * s/gnu-linux.h, s/hpux10-20.h, s/template.h, s/usg5-4-common.h:
9041 Move CLASH_DETECTION to configure.
9043 * s/gnu.h: Remove file, which is now empty.
9045 * s/gnu.h, s/gnu-linux.h:
9046 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
9048 2012-07-11 John Wiegley <johnw@newartisans.com>
9050 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9051 function attribute, so we only use it if it exists in the
9054 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9056 Avoid call to strlen in fast_c_string_match_ignore_case.
9057 * search.c (fast_c_string_match_ignore_case): Change to use
9058 length argument. Adjust users accordingly.
9059 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
9061 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

9078 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9080 Avoid calls to strlen in font processing functions.

9082 (font_open_by_name): Change to use length argument.
9083 Adjust users accordingly.
9084 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
9086 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
9087 Change to return ptrdiff_t.
9088 (xfont_list_pattern, xfont_match): Use length returned by
9089 xfont_decode_coding_xlfd.

9100 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
9102 Remove "#define unix" that is no longer needed (Bug#11905).
9103 * s/aix4-2.h (unix): Remove; no longer needed.
9105 EMACS_TIME simplification (Bug#11875).
9106 This replaces macros (which typically do not work in GDB)
9107 with functions, typedefs and enums, making the code easier to debug.
9108 The functional style also makes code easier to read and maintain.
9109 * systime.h: Include <sys/time.h> on all hosts, not just if
9110 WINDOWSNT, since 'struct timeval' is needed in general.
9111 (EMACS_TIME): Now a typedef, not a macro.
9112 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9114 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9116 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9117 (EMACS_TIME_LE): Now functions, not macros.
9118 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9119 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9120 which are not functions. All uses rewritten to use:
9121 (make_emacs_time): New function.
9122 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9123 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9124 not functions. All uses rewritten to use the following, respectively:
9125 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9126 (add_emacs_time, sub_emacs_time): New functions.
9127 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9128 * fileio.c (Fcopy_file):
9129 * xterm.c (XTflash): Get the current time closer to when it's used.
9130 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9134 Simplify by avoiding confusing use of strncpy etc.
9135 * doc.c (Fsnarf_documentation):
9136 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
9137 * frame.c (Fmake_terminal_frame):
9138 * gtkutil.c (get_utf8_string):
9140 * nsmenu.m (ns_update_menubar):
9141 * regex.c (regerror):
9142 Prefer memcpy to strncpy and strncat when either will do.
9143 * fileio.c (Fsubstitute_in_file_name):
9144 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9145 (menu_separator_name_p):
9146 * nsmenu.m (ns_update_menubar):
9147 Prefer memcmp to strncmp when either will do.
9148 * nsterm.m: Include <ftoastr.h>.
9150 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9151 Prefer snprintf to strncpy.
9152 * nsterm.m (ns_term_init):
9153 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9154 * nsterm.m (ns_term_init):
9155 Avoid the need for strncpy, by using build_string or
9156 make_unibyte_string directly. Use dtoastr, not snprintf.
9157 * process.c (Fmake_network_process): Diagnose service names that
9158 are too long, rather than silently truncating them or creating
9159 non-null-terminated names.
9160 (Fnetwork_interface_info): Likewise, for interface names.
9161 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9162 Prefer sprintf to strncat.
9163 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9164 Prefer vsnprintf to vsprintf + strncpy.
9166 2012-07-10 Glenn Morris <rgm@gnu.org>
9168 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9169 Clarify fallback case.
9171 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9173 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9174 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9175 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9176 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9177 where argument type is known to be a Lisp_Cons.
9179 2012-07-10 Tom Tromey <tromey@redhat.com>
9181 * bytecode.c (BYTE_CODE_THREADED): New macro.
9182 (BYTE_CODES): New macro. Replaces all old byte-code defines.
9183 (enum byte_code_op): New type.
9184 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

9187 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9189 Optimize pure C strings initialization.
9190 * lisp.h (make_pure_string): Fix prototype.
9191 (build_pure_c_string): New function, defined as static inline. This
9192 provides a better opportunity to optimize away calls to strlen when
9193 the function is called with compile-time constant argument.
9194 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9195 argument, adjust users accordingly. Use build_pure_c_string where
9197 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9198 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9199 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9201 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9203 Avoid calls to strlen in miscellaneous functions.
9204 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9205 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9206 * lread.c (openp): Likewise.
9208 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9210 Avoid calls to strlen in path processing functions.
9211 * fileio.c (file_name_as_directory): Add comment. Change to add
9212 srclen argument and return the length of result. Adjust users
9214 (directory_file_name): Fix comment. Change to add srclen argument,
9215 swap 1st and 2nd arguments to obey the common convention.
9216 Adjust users accordingly.
9217 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9219 2012-07-10 Glenn Morris <rgm@gnu.org>
9221 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9222 Move PENDING_OUTPUT_COUNT definition to configure.
9224 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9225 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9226 * s/gnu.h (DATA_START): Move definitions to configure.
9228 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9229 We include usg5-4-common.h, which defines them both.
9231 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9232 O_RDONLY already includes it).
9234 Stop ns builds setting the EMACSLOADPATH environment variable.
9235 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9236 Now it does not set EMACSLOADPATH, just returns the load-path string.
9237 * nsterm.h: Update accordingly.
9238 * lread.c [HAVE_NS]: Include nsterm.h.
9239 (init_lread) [HAVE_NS]: Use ns_load_path.
9240 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9242 2012-07-09 Glenn Morris <rgm@gnu.org>
9244 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9245 since the included bsd-common.h does so.
9247 Stop ns builds setting the EMACSPATH environment variable.
9248 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9249 (ns_init_paths): Do not set EMACSPATH.
9250 * nsterm.h (ns_exec_path): Add it.
9251 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9254 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9256 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9258 * process.c (wait_reading_process_output): 'waitchannels' was unset
9259 when read_kbd || !NILP (wait_for_cell); fix this.
9261 Add GCC-style 'const' attribute to functions that can use it.
9262 * character.h (char_resolve_modifier_mask):
9263 * keyboard.h (make_ctrl_char):
9264 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9265 (init_character_once, next_almost_prime, init_fns, init_image)
9266 (flush_pending_output, init_sound):
9267 * mem-limits.h (start_of_data):
9268 * menu.h (finish_menu_items):
9269 Add ATTRIBUTE_CONST.

9271 Declare the dummy function with ATTRIBUTE_CONST.
9272 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9273 Add decls with ATTRIBUTE_CONST.
9275 Minor improvements to make_formatted_string.
9276 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9277 where int is good enough, as vsprintf returns an int.
9278 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9280 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9282 Use make_formatted_string to avoid double length calculation.
9283 * lisp.h (make_formatted_string): New prototype.
9284 * alloc.c (make_formatted_string): New function.
9285 * buffer.c (Fgenerate_new_buffer_name): Use it.
9286 * dbusbind.c (syms_of_dbusbind): Likewise.

9289 * frame.c (make_terminal_frame, set_term_frame_name)
9290 (x_report_frame_params): Likewise.
9291 * image.c (gs_load): Likewise.
9292 * minibuf.c (get_minibuffer): Likewise.

9307 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9309 Move marker debugging code under MARKER_DEBUG.
9310 * marker.c (MARKER_DEBUG): Move marker debugging code under
9311 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9312 for bootstrap with --enable-checking (~3x slowdown reported
9313 by Juanma Barranquero <lekktu@gmail.com>).
9314 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9316 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9318 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9319 See <http://bugs.gnu.org/11825#29>.
9321 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9323 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9324 has no font, use the frame's font. (Bug#11813)
9325 (display_line): Add commentary about displaying truncation glyphs
9327 (produce_special_glyphs): Move here from term.c.
9329 * term.c (produce_special_glyphs): Move to xdisp.c.
9331 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9334 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9336 * xdisp.c (display_line): Avoid warning about implicit declaration
9339 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9341 * lisp.h: Remove empty conditional.
9343 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9345 * lread.c (load_path_check): Now static.
9347 Fix some minor --with-ns problems found by static checking.
9348 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9349 (x_set_font) [!HAVE_X_WINDOWS]:
9350 * image.c (xpm_load_image) [HAVE_NS]:
9351 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9352 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9353 Remove unused local.
9354 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9355 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9356 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9357 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9358 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9359 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9360 Fix pointer signedness problem.
9361 * xfaces.c (FRAME_X_FONT_TABLE):
9362 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9364 2012-07-07 Glenn Morris <rgm@gnu.org>
9366 * lread.c (load_path_check): New function, split from init_lread.
9367 (init_lread): Reorganize. Motivation:
9368 If EMACSLOADPATH is set, check/warn about that rather than the
9369 defaults, which we are not going to use. Hence we can remove
9370 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9371 Don't warn if site-lisp directories are missing.
9372 If not installed, start from a blank load-path, since
9373 PATH_LOADSEARCH refers to the eventual installation directories.
9375 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9377 Support truncation and continuation glyphs on GUI frames, when
9378 fringes are disabled. (Bug#11832)
9379 * xdisp.c (init_iterator): Get dimensions of truncation and
9380 continuation glyphs even if on GUI frames.
9381 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9382 or both, are absent.
9383 (start_display, move_it_in_display_line_to): Handle the case of a
9384 GUI frame without a fringe to display continuation or truncation
9386 (insert_left_trunc_glyphs): Support GUI frames: make sure
9387 truncation glyphs overwrite enough glyphs from the current line to
9388 have sufficient space in pixels.
9389 (display_line): Support truncation and continuation glyphs on GUI
9390 frames. If some spare pixels are left on the line after inserting
9391 the truncation glyphs, fill that space with a stretch glyph of a
9392 suitably computed width.
9394 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9395 produce_glyphs, to support GUI sessions.
9397 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9399 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9401 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9403 Do not require float-time's arg to fit in time_t (Bug#11825).
9404 This works better on hosts where time_t is unsigned, and where
9405 float-time is applied to the (negative) difference between two times.
9406 * editfns.c (decode_time_components): Last arg is now double *,
9407 not int *, and means to store all the result as a double, without
9408 worrying about whether the seconds part fits in time_t.
9409 All callers changed.
9410 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9411 All callers changed.
9412 (Ffloat_time): Do not fail merely because the specified time falls
9413 outside of time_t range.
9415 2012-07-07 Glenn Morris <rgm@gnu.org>
9417 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9418 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

9421 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9423 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9424 Update dependencies.
9426 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9428 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9430 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9431 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9432 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9433 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9434 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9435 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9437 * xfont.c (compare_font_names): Redo to omit the need for casts.
9439 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9441 * xfns.c (Fx_change_window_property): Doc fix.
9442 * w32fns.c (Fx_change_window_property): Doc fix.
9444 * w32fns.c (Fx_window_property): Accept the same arguments as the
9445 X Windows version. Doc fix.
9446 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9448 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9449 Eli Zaretskii <eliz@gnu.org>
9451 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9452 Windows-specific code from nt/config.nt moved here.
9453 Obsolete settings removed.
9455 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9457 * process.c: Avoid unnecessary calls to gettime.
9458 (wait_reading_process_output): Don't get the time of day
9459 when gobbling data immediately and not waiting, as there's no need
9460 for it in that case. This removes a FIXME.
9462 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9464 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9465 is defined (Bug#11768).
9467 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9469 Fix marker debugging code.
9470 * marker.c (byte_char_debug_check): Do not perform the check
9471 if buffer is not multibyte.
9472 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9473 Call byte_char_debug_check with correct arguments.
9475 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9477 Compile marker debugging code only if ENABLE_CHECKING is defined.
9478 * marker.c (byte_char_debug_check, count_markers):
9479 Use only if ENABLE_CHECKING is defined.
9480 (byte_debug_flag): Remove.
9481 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9482 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9484 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9486 Avoid code repetition in marker-related functions.
9487 * marker.c (attach_marker): New function.
9488 (Fset_marker, set_marker_restricted, set_marker_both)
9489 (set_marker_restricted_both): Use it.
9490 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9491 Consistently rename charno to charpos.
9492 (marker_position): Add eassert.
9493 (marker_byte_position): Convert to eassert.
9495 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9497 Simplify list operations in unchain_overlay and unchain_marker.
9498 * buffer.c (unchain_overlay): Simplify. Add comment.
9499 * marker.c (unchain_marker): Simplify. Fix comments.
9501 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9503 Introduce fast path for the widely used marker operation.
9504 * alloc.c (build_marker): New function.
9505 * lisp.h (build_marker): New prototype.
9506 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9507 * composite.c (autocmp_chars): Likewise.
9508 * editfns.c (buildmark): Remove.
9509 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9510 (save_restriction_save): Use build_marker.
9511 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9512 * window.c (save_window_save): Likewise.
9514 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9517 to avoid redundant calls to unchain_overlay.
9518 * buffer.c (drop_overlay): New function.
9519 (delete_all_overlays, Fdelete_overlay): Use it.
9520 * minibuf.c (get_minibuffer): Fix comment.
9522 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9524 Port to OpenBSD 5.1 amd64.
9525 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9526 This is needed for OpenBSD, and should be harmless on all BSD systems.
9527 Also, include <sys/sysctl.h>, as it should be available on all
9528 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9529 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9530 use p_pid member, not kp_proc.pid.
9532 2012-07-06 Glenn Morris <rgm@gnu.org>
9534 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9536 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9538 More xmalloc and related cleanup.
9539 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9546 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9547 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9549 Omit needless casts involving void * pointers and allocation.
9550 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9551 as the former is more robust if P's type is changed.
9552 Prefer xzalloc to xmalloc + memset 0.
9553 Simplify malloc-or-realloc to realloc.
9554 Don't worry about xmalloc returning a null pointer.
9555 Prefer xstrdup to xmalloc + strcpy.
9556 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9558 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9559 alloca of a constant.
9561 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9563 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9564 hscroll is larger than the line width. Fixes long and futile
9565 looping inside extend_face_to_end_of_line (on a TTY) producing
9566 glyphs that are not needed and thrown away.
9568 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9570 * marker.c (set_marker_restricted_both): Simplify by using
9573 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9575 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9577 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9579 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9580 not defined (Bug#11768).
9581 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9582 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9583 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9584 followed by gtk_box_set_homogeneous (Bug#11768).
9585 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9586 (update_theme_scrollbar_width, xg_create_scroll_bar):
9587 Use gtk_scrollbar_new (Bug#11768).
9588 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9589 (is_box_type): New function (Bug#11768).
9590 (xg_tool_item_stale_p): Call is_box_type.
9591 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9592 with default display (Bug#11768).
9594 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9596 * xdisp.c (window_hscroll_limited): New function.
9597 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9598 coordinates when window's hscroll is set to insanely large
9601 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9603 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9604 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9606 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9609 * lisp.h (xzalloc): New prototype. Omit needless casts.
9610 * alloc.c (xzalloc): New function. Omit needless casts.
9611 * charset.c: Omit needless casts. Convert all calls to
9612 xmalloc with following memset to xzalloc.

9662 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9664 * fileio.c (time_error_value): Check the right error number.
9665 Problem reported by Troels Nielsen in
9666 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9668 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9670 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9671 This should be fixed in a better way; see Eli Zaretskii in
9672 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9673 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9675 * fileio.c (time_error_value): Rename from special_mtime.
9676 The old name's problems were noted by Eli Zaretskii in
9677 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9679 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9680 This variable's comment says Emacs needs at least one GDB-visible
9681 symbol of type enum pvec_type, to work around GDB problems.
9682 The symbol's value doesn't matter.
9684 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9685 that causes compilation to fail on pre-C99 compilers.
9687 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9689 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9690 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9692 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9694 * buffer.c (init_buffer_once): Fix initialization of
9695 headers for buffer_defaults and buffer_local_symbols.
9696 Reported by Juanma Barranquero <lekktu@gmail.com>.
9698 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9700 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9701 * lisp.h (enum pvec_type): Use fewer bits.
9702 (PSEUDOVECTOR_SIZE_BITS): New constant.
9703 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9704 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9705 change in pvec_type.
9706 (PSEUDOVECTOR_TYPEP): New macro.
9707 (TYPED_PSEUDOVECTORP): Use it.
9708 * fns.c (internal_equal): Adapt code to extract pvectype.
9709 * emacs.c (gdb_pvec_type): Update type.
9710 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9711 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9712 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9713 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9714 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9715 abusing vector->header.next.nbytes.
9716 (live_vector_p): Use PVEC_TYPE.
9717 (mark_object): Adapt code to extract pvectype. Use switch.
9719 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9721 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9722 Tighten new eassert a bit.
9724 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9726 Fix compilation with --enable-gcc-warnings and -O1
9728 * doprnt.c (doprnt): Change type of tem to int, initialize
9729 to avoid compiler warning. Add eassert.
9730 * search.c (simple_search): Initialize match_byte to avoid
9731 compiler warning. Add eassert.
9733 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9735 Avoid weird behavior with large horizontal scrolls.
9736 Without this change, for example, large hscroll values would
9737 mess up Emacs's display on Fedora 15 x86, presumably due to
9738 overflows in int calculations in the display code.
9739 Also, if buffers had long lines, Emacs would freeze.
9740 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9741 (set_window_hscroll): New function, containing the old guts of
9742 Fset_window_hscroll. Return the clipped value.
9743 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9744 This avoids the need to check against PTRDIFF_MAX.
9746 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9748 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9750 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9752 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9754 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9755 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9756 since GCC 4.4.6 issues a bogus warning for them.
9758 Fix bugs in file timestamp newness comparisons.
9759 * fileio.c (Ffile_newer_than_file_p):
9760 * lread.c (Fload): Use full timestamp resolution of files,
9761 not just the 1-second resolution, so that files that are only
9762 slightly newer still count as newer.
9763 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9764 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9766 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9768 * fileio.c: Improve handling of file time marker. (Bug#11852)
9769 (special_mtime): New function.
9770 (Finsert_file_contents, Fverify_visited_file_modtime):
9771 Use it to set special mtime values consistently.
9773 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9775 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9776 marker for non-existing file. (Bug#11852)
9778 2012-07-03 Glenn Morris <rgm@gnu.org>
9780 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9781 and did not make it into globals.h).
9783 2012-07-03 Tom Tromey <tromey@redhat.com>
9785 * window.c (Fset_window_margins, Fset_window_fringes)
9786 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9787 * textprop.c (Fprevious_property_change): No longer static.
9788 * syntax.c (Fsyntax_table_p): No longer static.
9789 * process.c (Fget_process, Fprocess_datagram_address): No longer

9804 * composite.c (Fcomposition_get_gstring): No longer static.
9805 * callproc.c (Fgetenv_internal): No longer static.
9807 * ccl.h: Remove EXFUNs.

9809 * dispextern.h: Remove EXFUNs.
9810 * intervals.h: Remove EXFUNs.
9811 * fontset.h: Remove EXFUN.

9813 * dosfns.c (system_process_attributes): Remove EXFUN.
9814 * keymap.h: Remove EXFUNs.
9815 * lisp.h: Remove EXFUNs.
9816 * w32term.h: Remove EXFUNs.
9817 * window.h: Remove EXFUNs.
9818 * xsettings.h: Remove EXFUN.
9819 * xterm.h: Remove EXFUN.
9821 2012-07-03 Glenn Morris <rgm@gnu.org>
9823 * lisp.h (Frandom): Make it visible to C.
9824 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9825 buffer for invisible buffers. (Bug#1229)
9827 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9829 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9830 values which aren't power of 2.
9831 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9832 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9835 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9837 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9839 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9841 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9843 * alloc.c (allocate_vector_block): Remove redundant
9844 calls to mallopt if DOUG_LEA_MALLOC is defined.
9845 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9846 avoid calls to mallopt if zero_vector is returned.
9848 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9850 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9851 is enabled, avoid dereferencing NULL current_sblock if
9854 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9856 Cleanup basic buffer management.
9857 * buffer.h (struct buffer): Change layout to use generic vector
9858 marking code. Fix some comments. Change type of 'clip_changed'
9859 to bitfield. Remove unused #ifndef old.
9860 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9861 (GET_OVERLAYS_AT): Fix indentation.
9862 (for_each_per_buffer_object_at): New macro.
9863 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9864 (Fbuffer_local_variables): Use it.
9865 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9866 * alloc.c (allocate_buffer): Adjust to match new layout of
9867 struct buffer. Fix comment.
9868 (mark_overlay): New function.
9869 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9870 Lisp area of struct buffer.
9871 (mark_object): Use it. Adjust marking of misc objects
9872 and related comments.
9874 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9876 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9877 wrapper that is not needed because the wrapped code is a no-op (zero
9878 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9879 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9881 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9883 * alloc.c (mark_buffer): Simplify. Remove prototype.
9884 (mark_object): Add comment. Reorganize marking of vector-like
9885 objects. Use CHECK_LIVE for all vector-like objects except buffers
9886 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9887 Avoid redundant calls to mark_vectorlike for bool vectors.
9889 2012-06-30 Glenn Morris <rgm@gnu.org>
9891 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9893 * epaths.in (PATH_SITELOADSEARCH): New.
9894 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9895 This is rather than relying on --enable-locallisppath elements
9896 having "site-lisp" in their names. (Bug#10208#25, 11658)
9898 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9900 * w32proc.c (sys_select): Accept and ignore one more argument.
9902 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9904 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9905 (pselect) [!MS_DOS]: Redirect to sys_select.
9907 * sysdep.c: Don't include dos.h and dosfns.h.
9909 * process.c (sys_select):
9910 * msdos.c (sys_select): Accept one more argument and ignore it.
9912 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9913 adapt data types and code to that.
9916 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9917 which clashes with the gnulib function of the same name.
9919 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9921 * font.c (font_style_to_value, font_style_symbolic)
9922 (font_prop_validate_style): Add type checks for values in
9925 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9927 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9930 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9932 * xdisp.c (try_window_id): Undo last change.
9934 * w32.c (getwd): Adjust commentary about startup_dir.
9935 (init_environment): Always call sys_access, even in non-MSVC
9936 builds. Don't chdir to the directory of the Emacs executable.
9937 This undoes code from 1997 which was justified by the need to
9938 "avoid conflicts when removing and renaming directories". But its
9939 downside was that every relative file name was being interpreted
9940 relative to the directory of the Emacs executable, which can never
9941 be TRT. In particular, it broke sys_access when called with
9942 relative file names.
9943 (sys_access): Map GetLastError to errno.
9945 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9947 * window.h (struct window): Change type of 'fringes_outside_margins'
9948 to bitfield. Fix comment. Adjust users accordingly.

10137 Use sprintf return value instead of invoking strlen on result.
10138 In the old days this wasn't portable, since some sprintf
10139 implementations returned char *. But they died out years ago and
10140 Emacs already assumes sprintf returns int.
10141 Similarly for float_to_string.

10150 Use sprintf or float_to_string result to avoid need to call strlen.
10151 * data.c (Fnumber_to_string):
10152 Use make_unibyte_string, since the string must be ASCII.
10153 * lisp.h, print.c (float_to_string): Now returns int length.
10154 * term.c (produce_glyphless_glyph):
10155 Use sprintf result rather than recomputing it.
10157 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10165 strcasecmp if available.

10186 * xfns.c (x_window): Remove redundant cast.
10188 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10190 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10191 `const char *' to `char *' to avoid compiler warning.
10193 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10195 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10196 instead of truncating it to 63 (admittedly a generous limit).
10198 * process.c: Fix spelling and caps in comments.

10256 * keyboard.c (kbd_buffer_get_event):
10257 * process.c (Faccept_process_output):
10258 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10259 This improves on the previous patch, which introduced a bug
10260 when time_t is unsigned and as wide as intmax_t.
10261 See <http://bugs.gnu.org/9000#51>.
10263 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10292 language ID in the event parameters.
10294 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10295 event.code, not the obscure "character set ID".

10328 Support higher-resolution time stamps (Bug#9000).
10329 The time stamps are only nanosecond-resolution at the C level,
10330 since that's the best that any real-world system supports now.
10331 But they are picosecond-resolution at the Lisp level, as that's
10332 easy, and leaves room for future OS improvements.
10334 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10337 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10338 Don't get current time unless it's needed.
10340 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10341 now provides it if it's absent.
10342 (start_atimer): Port to higher-res time stamps.
10343 Check for time stamp overflow. Don't get current time more
10344 often than is needed.
10346 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10347 Include systime.h, not time.h.

10350 * dired.c: Include stat-time.h.
10351 (Ffile-attributes): File times now have higher resolution.
10353 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10354 (struct image): Timestamp now has higher resolution.
10356 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10357 has at least microseconds now. All uses removed.
10358 (update_frame, update_single_window, update_window, update_frame_1)
10359 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10360 (duration_to_sec_usec): Remove; no longer needed.
10362 * editfns.c (time_overflow): Now extern.
10363 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10364 (float-time, Fformat_time_string, Fcurrent_time_string)

10368 (decode_time_components, lisp_seconds_argument): New functions.
10369 (make_time): Now static.
10370 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10371 Report an error if the time is invalid, rather than having the caller
10374 * fileio.c: Include <stat-time.h>
10375 (Fcopy_file): Copy higher-resolution time stamps.
10376 Prefer to set the time stamp via a file descriptor if that works.
10377 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10378 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10379 (Fvisited_file_modtime, Fset_visited_file_modtime):
10380 Support higher-resolution time stamps.
10382 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10384 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10386 * image.c (prepare_image_for_display, clear_image_cache)
10387 (lookup_image): Port to higer-resolution time stamps.
10389 * keyboard.c (start_polling, bind_polling_period):
10390 Check for time stamp overflow.
10391 (read_char, kbd_buffer_get_event, timer_start_idle)
10392 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10393 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10394 Port to higher-resolution time stamps. Do not assume time_t is signed.
10395 (decode_timer): New function. Timers are now vectors of length 9,
10396 not 8, to accommodate the picosecond component.
10397 (timer_check_2): Use it.
10399 * nsterm.m (select_timeout, timeval_subtract): Remove.
10400 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10401 as they're a bit more accurate and handle overflow better.
10402 (ns_select): Change prototype to be compatible with pselect.
10403 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10404 * nsterm.h (ns_select): Adjust prototype.
10406 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10407 us-resolution time stamps.
10408 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10410 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10412 * lisp.h (time_overflow): New decl.
10413 (wait_reading_process_output): First arg is now intmax_t, not int,
10414 to accommodate larger waits.
10416 * process.h (struct Lisp_Process.read_output_delay):
10417 Now counts nanoseconds, not microseconds.
10418 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10420 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10421 (wait_reading_process_output):
10422 Port to ns-resolution time stamps.
10423 (Faccept_process_output, wait_reading_process_output):
10424 Check for time stamp overflow. Do not assume time_t is signed.
10425 (select_wrapper): Remove; we now use pselect.
10426 (Fprocess_attributes): Now generates ns-resolution time stamps.
10428 * sysdep.c: Include utimens.h. Don't include utime.h
10429 or worry about struct utimbuf; gnulib does that for us now.
10430 (gettimeofday): Remove; gnulib provides a substitute.
10431 (make_timeval): New function.
10432 (set_file_times): Now sets ns-resolution time stamps.
10433 New arg FD; all uses changed.

10436 Now returns ns-resolution time stamp. All uses changed.
10437 Check for time stamp overflow.

10440 provides a substitute now.
10442 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10443 since it guarantees struct timespec.
10444 (EMACS_TIME): Now struct timespec, so that we can support
10445 ns-resolution time stamps.
10446 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10447 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10448 (EMACS_USECS): Remove.
10449 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10450 so multiply the arg by 1000 before storing it.

10460 (make_timeval, make_lisp_time, decode_time_components): New decls.
10461 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10462 that it mishandled time_t overflow. You can't compare by subtracting!
10463 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10464 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10466 * term.c: Include <sys/time.h>.
10467 (timeval_to_Time): New function, for proper overflow wraparound.
10468 (term_mouse_position, term_mouse_click): Use it.
10470 * undo.c (record_first_change): Support higher-resolution time stamps
10471 in the undo buffer.
10472 (Fprimitive_undo): Use them when restoring time stamps.
10474 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10475 (w32_get_internal_run_time):
10476 Port to higher-resolution Emacs time stamps.
10477 (ltime): Now accepts single 64-bit integer, as that's more convenient
10480 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10482 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10483 for compatibility with pselect. Support ns-resolution time stamps.
10485 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10487 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10488 Check for time stamp overflow, and support ns-resolution time stamps.
10490 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10491 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10492 (timeval_subtract): Remove; no longer needed.
10493 (XTflash, XTring_bell, x_wait_for_event):
10494 Port to ns-resolution time stamps. Don't assume time_t is signed.

10503 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10504 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10505 staticidx goes up to 1597 out of 1600 = 0x640.)
10507 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10509 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10510 Otherwise, the umask might be mistakenly 0 while handling input signals.
10512 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

10530 frame's selected window and its terminal's top-frame.
10531 (unwind_format_mode_line): Restore them.
10532 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10534 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10535 since tty frames can be explicitly named.
10536 (prepare_menu_bars): Likewise.
10538 * term.c (Ftty_top_frame): New function.
10540 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10542 Port byte-code-meter to modern targets.
10543 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10544 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10545 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10546 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10553 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10555 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10556 gets killed during executing of this function (Bug#11665).
10557 Try to always return Qt when the buffer has been actually killed.
10558 (Vkill_buffer_query_functions): In doc-string say that functions
10559 run by this hook should not change the current buffer.
10561 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10563 Fix recently-introduced process.c problems found by static checking.

10581 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10583 * lisp.h (eassert): Assume C89 or later.
10584 This removes the need for CHECK.
10585 (CHECK): Remove. Its comments about always evaluating its
10586 argument were confusing, as 'eassert' typically does not evaluate
10589 * coding.c (produce_chars): Use ptrdiff_t, not int.
10591 * xterm.c (x_draw_underwave): Check for integer overflow.
10592 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10780 Use an inline function on all platforms when using the union type,

10867 * xdisp.c (vmessage): Treat frame message as multibyte.
10868 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10869 would generate the diagnostic "Making \302\247 buffer-local while

10874 * dispnew.c (showing_window_margins_p): Undo last change, which
10875 was done due to an inadvertent commit.
10876 (adjust_frame_glyphs_for_frame_redisplay): Do call
10877 showing_window_margins_p.
10879 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
10881 * eval.c (Fmake_var_non_special): New primitive.

10887 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
10888 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
10890 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10892 * alloc.c (allocate_vectorlike): Fix last change.
10894 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
10896 Block-based vector allocation of small vectors.
10897 * lisp.h (struct vectorlike_header): New field `nbytes',
10898 adjust comment accordingly.
10899 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10900 to denote vector blocks. Adjust users (live_vector_p,
10901 mark_maybe_pointer, valid_lisp_object_p) accordingly.
10902 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
10903 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

10912 (sweep_vectors): New functions.
10913 (allocate_vectorlike): Return `zero_vector' as the only vector of
10914 0 items. Allocate new vector from block if vector size is less than
10915 or equal to VBLOCK_BYTES_MAX.
10916 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
10917 (init_alloc_once): Add call to init_vectors.
10919 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
10921 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
10923 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10925 * doprnt.c (doprnt): Truncate multibyte char correctly.
10926 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10927 would mishandle a string argument "Xc" if X was a multibyte
10928 character of length 2: it would truncate after X's first byte
10929 rather than including all of X.
10931 2012-06-06 Chong Yidong <cyd@gnu.org>
10933 * buffer.c (word_wrap): Doc fix.
10935 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10947 binary via PaX flags if the paxctl utility is available.
10948 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10949 Restore PaX flags to their default. (Bug#11398)
10951 2012-06-03 Chong Yidong <cyd@gnu.org>
10953 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10954 buffer (Bug#11226).

10958 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
10959 (note_mode_line_or_margin_highlight): If there is no help echo,
10960 use mode-line-default-help-echo. Handle the case where the mouse
10961 position is past the end of the mode line string.
10963 * buffer.c (buffer_local_value_1): New function, split from
10964 Fbuffer_local_value; can return Qunbound.
10965 (Fbuffer_local_value): Use it.
10966 (Vmode_line_format): Docstring tweaks.
10968 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10980 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10982 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10983 Convert pctcpu and pctmem to Lisp float properly.
10984 Let the compiler fold better, as 100.0/0x8000 is exact.
10986 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10988 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10991 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10995 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10997 For a 'struct window', replace some Lisp_Object fields to
10998 bitfields where appropriate, remove unused fields.
10999 * window.h (struct window): Remove unused 'last_mark_x' and
11000 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11001 change its type from Lisp_Object to bitfield.
11002 Change type of 'force_start', 'optional_new_start',
11003 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11004 fields from Lisp_Object to bitfield. Adjust users accordingly.
11006 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11008 Pacify gcc -Wdouble-precision when using Xaw.
11009 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11010 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11011 Use 'float' consistently, rather than 'float' in most places
11012 and 'double' in a couple of places.
11014 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11016 * xdisp.c (handle_stop): Detect whether we have overlay strings
11017 loaded by testing it->current.overlay_string_index to be
11018 non-negative, instead of checking whether n_overlay_strings is
11019 positive. (Bug#11587)
11021 2012-05-31 Chong Yidong <cyd@gnu.org>
11023 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11027 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11029 * search.c (search_buffer): Remove calls to
11030 r_alloc_inhibit_buffer_relocation, as it is now called by
11031 maybe_unify_char, which was the cause of relocation of buffer text
11034 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11036 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11037 for the duration of call to load_charset, to avoid problems with
11038 callers of maybe_unify_char that access buffer text through C
11041 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11042 decrement the inhibition flag, instead of just setting or
11045 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11047 Remove obsolete '#define static' cruft.
11048 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11049 This #undef was "temporary" in 2000; it is no longer needed
11050 now that '#define static' has gone away.
11051 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11052 (gray_bitmap_bits): Remove; no longer needed.
11053 All uses replaced with definiens.
11054 * xterm.c: Include "bitmaps/gray.xbm".
11056 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

11059 The following changes affect the code only when profiling.
11060 * dispnew.c (__executable_start): Rename from safe_bcopy.
11061 Define only on platforms that need it.
11062 * emacs.c: Include <sys/gmon.h> when profiling.
11063 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11064 (__executable_start): Remove decl, since lisp.h does it now.
11065 (safe_bcopy): Remove decl; no longer has that name.
11066 (main): Coalesce #if into single bit of code, for simplicity.
11067 Cast pointers to uintptr_t, since standard libraries want integers
11069 * lisp.h (__executable_start): New decl.
11071 2012-05-31 Glenn Morris <rgm@gnu.org>
11073 * image.c (Fimagemagick_types): Doc fix.

11091 * lisp.h (Qdefun): Remove.
11092 * lread.c (read1): Tiny simplification.
11094 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11096 Do not create empty overlays with the evaporate property (Bug#9642).
11097 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11098 Bug#9642, but explicitly check that the buffer the overlay would
11099 be moved to is live and rearrange lines to make sure that errors
11100 will not put the overlay in an inconsistent state.
11101 (Fdelete_overlay): Cosmetics.
11103 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11105 * w32term.c (my_bring_window_to_top): New function.
11106 (x_raise_frame): Use handle returned by DeferWindowPos, which
11107 could be different from the original one.
11108 Call my_bring_window_to_top instead of my_set_foreground_window.

11117 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11119 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11120 This avoids undefined behavior that might cause the eassert
11121 to not catch an out-of-range value.
11123 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11125 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11126 Update dependencies.
11128 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11130 * bidi.c (bidi_mirror_char): Fix last change.
11132 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11137 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11139 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11140 Only r_alloc_inhibit_buffer_relocation needed to be added;
11141 the others were already declared.
11143 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11144 before checking whether it's out of range. Put the check inside
11146 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11148 2012-05-27 Ken Brown <kbrown@cornell.edu>
11150 * callproc.c (Fcall_process): Restore a line that was accidentally
11151 commented out in the 2011-02-13 change (bug#11547).
11153 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11155 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11156 defined on ralloc.c.
11158 * buffer.c [REL_ALLOC]: Remove prototypes of
11159 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11160 they are now on lisp.h.
11162 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11164 * search.c (search_buffer): Use it to inhibit relocation of buffer
11165 text while re_search_2 is doing its job, because re_search_2 is
11166 passed C pointers to buffer text. (Bug#11519)
11168 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11169 Update value to 24.
11171 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11172 state after an additional call to move_it_in_display_line_to, keep
11173 the values of it->max_ascent and it->max_descent found for the
11175 (pos_visible_p): Revert the comparison against bottom_y to what it
11176 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11179 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11181 Fix coding-related core dumps with gcc -ftrapv.
11182 The code was computing A - B, where A and B are pointers, and B is
11183 random garbage. This can lead to core dumps on platforms that
11184 have special pointer registers, and it also leads to core dumps on
11185 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11186 A - B only when B is initialized properly.
11187 * coding.c (coding_set_source, coding_set_destination): Return void.
11188 (coding_change_source, coding_change_destinations): New functions,
11189 with the old behaviors of coding_set_source and coding_set_destination.
11190 All callers that need an offset changed to use these new functions.
11192 2012-05-26 Glenn Morris <rgm@gnu.org>
11194 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11196 2012-05-26 Eli Zaretskii <eliz@gnu.org>

11199 * xdisp.c (draw_row_with_mouse_face):
11200 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11202 * w32console.c: Include window.h.
11203 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11205 (initialize_w32_display): Initialize mouse-highlight data.
11207 * w32inevt.c: Include termchar.h and window.h.
11208 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11209 moves, call note_mouse_highlight. If help_echo changed, call
11210 gen_help_event to produce help-echo message in the echo area.
11211 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11214 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11216 * lread.c (read1): Simplify slightly to avoid an overflow warning
11217 with GCC 4.7.0 on x86-64.
11219 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11221 * bidi.c (bidi_mirror_char): Revert last change: an int is
11222 definitely wide enough here.
11224 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11226 Fix integer width and related bugs (Bug#9874).

11233 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11234 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11236 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11237 (allocate_pseudovector):
11238 Use int, not EMACS_INT, where int is wide enough.
11239 (inhibit_garbage_collection, Fgarbage_collect):
11240 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11241 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11242 int might not be wide enough.
11243 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11244 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11245 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11246 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11247 (bidi_level_of_next_char, bidi_move_to_visually_next):
11248 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11249 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11250 (Fkill_buffer, Fset_buffer_major_mode)
11251 (advance_to_char_boundary, Fbuffer_swap_text)
11252 (Fset_buffer_multibyte, overlays_at, overlays_in)
11253 (overlay_touches_p, struct sortvec, record_overlay_string)
11254 (overlay_strings, recenter_overlay_lists)
11255 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11256 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

11258 (Foverlay_recenter, last_overlay_modification_hooks_used)
11259 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11260 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11261 (validate_region): Omit unnecessary test for b <= e,
11262 since that's guaranteed by the previous test.
11263 (adjust_overlays_for_delete): Avoid pos + length overflow.
11264 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11265 (report_overlay_modification):
11266 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11267 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11268 Omit pointer cast, which isn't needed anyway, and doesn't work
11269 after the EMACS_INT -> ptrdiff_t change.
11270 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11271 * buffer.h: Adjust decls to match defn changes elsewhere.
11272 (struct buffer_text, struct buffer):
11273 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11274 Use EMACS_INT, not int, where int might not be wide enough.
11275 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11276 not int, to avoid needless 32-bit limit on 64-bit hosts.
11277 (exec_byte_code): Use tighter memory-full test, one that checks
11278 for alloca overflow. Don't compute the address of the object just
11279 before an array, as that's not portable. Use EMACS_INT, not
11280 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11281 * callint.c (Fcall_interactively):
11282 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11283 * callproc.c (call_process_kill, Fcall_process):
11284 Don't assume pid_t fits into an Emacs fixnum.

11293 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11294 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11295 (casify_object): Avoid integer overflow when overallocating buffer.
11296 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11297 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

11299 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11300 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11301 integers are now checked earlier. All uses replaced with XINT.
11303 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11304 For CCL_MapSingle, check that content and value are in int range.
11305 (ccl_driver, Fregister_code_conversion_map):
11306 Check that Vcode_version_map_vector is a vector.
11307 (resolve_symbol_ccl_program): Check that vector header is in range.
11308 Always copy the vector, so that we can check its contents reliably
11309 now rather than having to recheck each instruction as it's being
11310 executed. Check that vector words fit in 'int'.
11311 (ccl_get_compiled_code, Fregister_ccl_program)
11312 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11313 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11314 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11315 contents are in range.
11316 (Fccl_execute_on_string): Check that status is in range.
11317 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11318 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

11326 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11327 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11328 avoid mishandling large integers.
11329 * character.h: Adjust decls to match defn changes elsewhere.
11330 * charset.c (load_charset_map_from_file, find_charsets_in_text)

11338 (Fdefine_charset_internal): Check ranges here, more carefully.
11339 Don't rely on undefined behavior with signed left shift overflow.
11340 Don't assume unsigned int fits into fixnum, or that fixnum fits
11341 into unsigned int. Don't require max_code to be a valid fixnum;
11342 that's not true for gb10830 4-byte on a 32-bit host. Allow
11343 invalid_code to be a cons, for the same reason. Require code_offset
11344 to be a character. Avoid int overflow if max_char is close
11346 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11347 this is intended anyway and avoids some undefined behavior.
11348 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11349 INDEX_TO_CODE_POINT, as that's what it expects.
11350 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11351 * charset.h (DECODE_CHAR): Return int, not unsigned;
11352 this is what was intended anyway, and it avoids undefined behavior.
11353 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11354 integer-overflow issues.
11355 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11356 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11357 where the argument is EMACS_INT, and this behavior is not intended.
11358 * chartab.c (Fmake_char_table, Fset_char_table_range)
11359 (uniprop_get_decoder, uniprop_get_encoder):
11360 Don't assume fixnum fits in int.
11361 * cmds.c (move_point): New function, that does the gist of
11362 Fforward_char and Fbackward_char, but does so while checking
11363 for integer overflow more accurately.
11364 (Fforward_char, Fbackward_char): Use it.
11365 (Fforward_line, Fend_of_line, internal_self_insert)
11366 (internal_self_insert):
11367 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11969 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
11970 (handle_tool_bar_click):
11971 Use int, not unsigned, since we prefer signed and the signedness
11972 doesn't matter here.
11973 (get_next_display_element, next_element_from_display_vector):
11974 Use int, not EMACS_INT, when int is wide enough.
11975 (start_hourglass): Use duration_to_sec_usec to do proper
11976 overflow checking on durations.
11977 * xfaces.c (Fbitmap_spec_p):
11978 Check that fixnums are in proper range for system types.
11979 (compare_fonts_by_sort_order):
11980 Avoid mishandling comparisons due to subtraction overflow.
11981 (Fx_family_fonts, realize_basic_faces):
11982 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11984 Don't assume fixnum fits in int.
11985 Use SAFE_ALLOCA_LISP, not alloca.
11986 (merge_face_heights): Remove unnecessary cast to EMACS_INT.

11995 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
11996 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):

11998 (Fx_change_window_property): Don't assume fixnums fit in int.
11999 * xfont.c (xfont_chars_supported):
12000 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12001 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
12002 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):

12008 (x_get_local_selection, x_reply_selection_request)
12009 (x_handle_selection_request, wait_for_property_change):
12010 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12011 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12012 short is wide enough.
12013 (x_send_client_event): Don't assume fixnum fits in int.
12014 * xterm.c (x_x_to_emacs_modifiers):
12015 Don't assume EMACS_INT overflows nicely into int.
12016 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12017 may come from Lisp.
12018 (handle_one_xevent): NATNUMP can eval its arg twice.
12019 (x_connection_closed):
12020 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12021 * xterm.h: Adjust decls to match defn changes elsewhere.
12022 (struct scroll_bar): Use struct vectorlike_header
12023 rather than rolling our own approximation.
12024 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12026 2012-05-25 Glenn Morris <rgm@gnu.org>
12028 * lisp.mk (lisp): Update for more files being compiled now.
12030 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12032 * lread.c: Remove `read_pure' which makes no difference.
12033 (read_pure): Remove var.
12034 (unreadpure): Remove function.
12035 (readevalloop): Don't call read_list with -1 flag.
12036 (read1, read_vector): Don't test read_pure any more.
12037 (read_list): Simplify.
12039 * fileio.c, character.h: Minor style tweaks.
12041 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12043 * window.h (clip_changed): Remove useless declaration.
12045 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12047 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12048 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12050 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12053 This directory predates autoconf and is no longer needed nowadays.
12054 Move its few remaining bits of functionality to where they're needed.
12055 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12056 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12057 * m/template.h: Remove.
12058 * Makefile.in (M_FILE): Remove. All uses removed.
12059 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12060 * lisp.h (USE_LSB_TAG):
12061 * mem-limits.h (EXCEEDS_LISP_PTR):
12062 Use VAL_MAX, not VALBITS, in #if.
12063 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12064 (EMACS_UINT): Define unconditionally now.
12065 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12066 (BITS_PER_EMACS_INT): New constants, replacing
12067 what used to be in config.h, but not useful in #if.
12068 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12069 define them any more.
12070 (VAL_MAX): New macro.
12072 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12073 BITS_PER_EMACS_INT, in #if.
12074 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12075 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12076 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12077 * s/ms-w32.h (DATA_START):
12078 Move here from removed file m/intel386.h.
12079 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12080 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12082 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12084 Assume C89 or later.
12085 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12086 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12088 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12089 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):

12094 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12095 * xterm.c (input_signal_count): Assume volatile works.
12097 2012-05-21 Ken Brown <kbrown@cornell.edu>
12099 * xgselect.c (xg_select): Fix first argument in call to 'select'
12102 2012-05-20 Ken Brown <kbrown@cornell.edu>
12104 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12105 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12107 2012-05-19 Ken Brown <kbrown@cornell.edu>
12109 * xfns.c (x_in_use): Remove `static' qualifier.
12110 * xterm.h (x_in_use): Declare.
12111 * xgselect.c: Include xterm.h.
12112 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12113 and `display_arg' (bug#9754).
12115 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12117 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12119 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12120 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12122 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12124 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12126 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12127 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12129 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12130 reference to image_cache->refcount.
12131 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12133 2012-05-17 Juri Linkov <juri@jurta.org>
12135 * search.c (Fword_search_regexp, Fword_search_backward)
12136 (Fword_search_forward, Fword_search_backward_lax)
12137 (Fword_search_forward_lax): Move functions to isearch.el
12138 (bug#10145, bug#11381).
12140 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12142 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12144 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12146 * lread.c (init_obarray): Declare Qt and Qnil as special.
12148 2012-05-14 Glenn Morris <rgm@gnu.org>
12150 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12151 Put "libexec" before "bin", for the sake of init_callproc_1.
12153 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12155 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12157 * unexaix.c: Port to more-recent AIX compilers.
12158 (report_error, report_error_1, make_hdr, copy_sym)
12159 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12160 Make arguments const char *, not char *, to avoid violations of C
12161 standard and to fix some AIX warnings reported by Gilles Pion.
12163 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12165 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12166 already have overlays loaded.
12167 (handle_single_display_spec): Before returning without displaying
12168 fringe bitmap, synchronize the bidi iterator with the main display
12169 iterator, by calling iterate_out_of_display_property.
12170 (iterate_out_of_display_property): Detect buffer iteration by
12171 testing that it->string is a Lisp string.
12172 (get_next_display_element): When the current object is exhausted,
12173 and there's something on it->stack, call set_iterator_to_next to
12174 proceed with what's on the stack, instead of returning zero.
12175 (set_iterator_to_next): If called at the end of a Lisp string,
12176 proceed to consider_string_end without incrementing string
12177 position. Don't increment display vector index past the end of
12178 the display vector. (Bug#11417)
12179 (pos_visible_p): Don't report a position visible when move_it_to
12180 stopped at the last line of window, which happens to be scanned
12181 backwards by the bidi iteration. (Bug#11464)
12183 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12185 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12186 and right-margin display specs even if the spec is invalid or we
12187 are on a TTY, and thus unable to display on the fringes.
12188 That's because the text with the property will not be displayed anyway,
12189 so we need to signal to the caller that this is a "replacing"
12190 display spec. This fixes display when the spec is invalid or we
12193 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12195 * unexaix.c (make_hdr): Fix typo in prototype.
12196 This bug broke the build on AIX. Problem reported by Gilles Pion.
12198 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12200 * keyboard.c (kbd_buffer_get_event): Read special events also in
12201 batch mode. (Bug#11415)
12203 2012-05-12 Glenn Morris <rgm@gnu.org>
12205 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12207 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12209 * lisp.mk (lisp): Add newcomment.elc.
12211 2012-05-12 Glenn Morris <rgm@gnu.org>
12213 * Makefile.in (MKDIR_P): New, set by configure.
12214 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12216 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12218 Remove unused function hourglass_started.
12219 * dispextern.h (hourglass_started):
12220 * w32fns.c (hourglass_started):
12221 * xdisp.c (hourglass_started): Remove.
12223 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12225 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12226 Update dependencies.
12228 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12230 * xgselect.c (xg_select): Put maxfds+1 into a var.
12231 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12233 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12235 2012-05-10 Dave Abrahams <dave@boostpro.com>
12237 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12238 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12240 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12242 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12243 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12244 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12245 Initialize xd_registered_buses.
12247 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12249 Untag more efficiently if USE_LSB_TAG.
12250 This is based on a proposal by YAMAMOTO Mitsuharu in
12251 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12252 For an admittedly artificial (nth 8000 longlist) benchmark on
12253 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12254 Emacs's overall text size by 1%.
12255 * lisp.h (XUNTAG): New macro.
12256 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12257 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12258 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12259 * eval.c (Fautoload):
12260 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12261 * frame.h (XFRAME): Use XUNTAG.
12263 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12264 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12265 Remove unportable assumptions about print widths of types like
12267 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12268 intptr_t when converting between pointer and integer, to avoid GCC
12269 warnings about wrong width.
12271 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12273 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12274 stack for each reader_thread, instead of defaulting to 8MB
12275 determined by the linker. This avoids failures in creating
12276 subprocesses on Windows 7, see the discussion in this thread:
12277 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12279 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12281 Fix up display of the *Minibuf-0* buffer in the mini window.
12282 * keyboard.c (read_char): Don't clear the echo area if there's no
12284 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12285 contents of *Minibuf-0*) if there's no message displayed in its stead.
12287 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12289 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12292 2012-05-06 Chong Yidong <cyd@gnu.org>
12294 * lisp.mk (lisp): Update.
12296 2012-05-05 Jim Meyering <meyering@redhat.com>
12298 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12300 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12302 * data.c (PUT_ERROR): New macro.
12303 (syms_of_data): Use it. Add new error type `user-error'.
12304 * undo.c (user_error): New function.
12305 (Fprimitive_undo): Use it.
12306 * print.c (print_error_message): Adjust print style for `user-error'.
12307 * keyboard.c (user_error): New function.
12308 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12310 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12312 Do not limit current-time-string to years 1000..9999.
12313 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12314 (Fcurrent_time_string): Support any year that is supported by the
12315 underlying localtime representation. Don't use asctime, as it
12316 has undefined behavior for years outside the range -999..9999.
12318 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12320 Fix race conditions involving setenv, gmtime, localtime, asctime.
12321 Without this fix, interrupts could mess up code that uses these
12322 nonreentrant functions, since setting TZ invalidates existing
12323 tm_zone or tzname values, and since most of these functions return
12324 pointers to static storage.
12325 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12326 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12327 Grow the critical sections to include not just invoking
12328 localtime/gmtime, but also accessing these functions' results
12329 including their tm_zone values if any, and any related TZ setting.
12330 (format_time_string): Last arg is now struct tm *, not struct tm **,
12331 so that the struct tm is saved in the critical section.
12332 All callers changed. Simplify allocation of initial buffer, partly
12333 motivated by the fact that memory allocation needs to be outside
12334 the critical section.
12336 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12338 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12339 with RESET_INTERVAL.
12341 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12342 Remove duplicated buffer name initialization.
12344 2012-05-02 Jim Meyering <jim@meyering.net>
12346 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12348 * xfns.c (x_window): Use xstrdup (Bug#11375).
12350 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12352 * xdisp.c (pos_visible_p): If already at a newline from the
12353 display string before the 'while' loop, don't walk back the glyphs
12354 from it3.glyph_row. Solves assertion violation when the display
12355 string begins with a newline (egg.el). (Bug#11367)
12357 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12359 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12362 2012-05-01 Glenn Morris <rgm@gnu.org>
12364 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12365 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12366 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12367 All were removed before 23.1.
12369 * dispnew.c: Remove HAVE_LIBNCURSES test;
12370 it is always true on relevant platforms.
12372 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12373 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12375 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12377 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12379 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12380 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12383 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12385 Do not avoid creating empty evaporating overlays (Bug#9642).
12386 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12387 That is, do not delete an evaporating overlay if it becomes
12388 empty after its bounds are adjusted to fit within its buffer.
12389 This fix caused other problems, and I'm reverting it until we get
12390 to the bottom of them.
12392 2012-04-27 Chong Yidong <cyd@gnu.org>
12394 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12396 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12398 * xdisp.c (pos_visible_p): If the window start position is beyond
12399 ZV, start the display from buffer beginning. Prevents assertion
12400 violation in init_iterator when the minibuffer window is scrolled
12401 via the scroll bar.
12403 * window.c (window_scroll_pixel_based): Likewise.
12405 2012-04-27 Chong Yidong <cyd@gnu.org>

12411 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12412 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12414 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12416 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12417 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12419 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12421 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12422 display element, check also the underlying string or buffer
12423 character. (Bug#11341)
12425 * w32menu.c: Include w32heap.h.
12426 (add_menu_item): If the call to AppendMenuW (via
12427 unicode_append_menu) fails, disable Unicode menus only if we are
12428 running on Windows 9X/Me.
12430 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12432 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12433 (xgetint): Add missing shift for LSB tags.

12449 now a cons (bug#11311).
12451 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12453 Do not create empty overlays with the evaporate property (Bug#9642).
12454 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12455 if it becomes empty after its bounds are adjusted to fit within
12456 its buffer. Without this fix, in a nonempty buffer (let ((o
12457 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12458 yields an empty overlay that has the evaporate property, which is
12459 not supposed to happen.

12576 * sysdep.c [__FreeBSD__]: Minor cleanups.
12577 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12578 Use Emacs indenting style more consistently. Avoid some casts.
12579 Use 'double' consistently rather than mixing 'float' and 'double'.

12583 * sysdep.c (list_system_processes, system_process_attributes):
12584 Add implementation for FreeBSD (Bug#5243).

12604 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12605 set the status to "failed" and ensure that sentinel is run.
12607 2012-04-20 Glenn Morris <rgm@gnu.org>
12609 * process.c (Fset_process_inherit_coding_system_flag)

12660 New extern decls, to avoid calling undeclared functions.
12661 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12662 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12663 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12664 (NEED_MEM_INSERT): New macro.
12665 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12666 Remove one incorrect comment and fix another.

12702 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12703 * s/netbsd.h, s/sol2-6.h:
12704 Remove definition of GC_MARK_STACK, since the default now works.
12705 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12733 2012-04-11 Daniel Colascione <dancol@dancol.org>
12735 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12736 against is gone. It's better to use vfork now so that when Cygwin
12737 gains a new, working vfork, we use it automatically (bug#10398).
12739 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12762 2012-04-09 Glenn Morris <rgm@gnu.org>
12764 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

12780 (emacs_gnutls_read): Use new log functions,
12781 `gnutls_handshakes_tried' process member, and
12782 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12783 attempts per process (connection).
12785 2012-04-09 Chong Yidong <cyd@gnu.org>
12787 * eval.c (Fuser_variable_p, user_variable_p_eh)

12789 (Fdefvar): Caller changed.
12791 * callint.c (Finteractive, Fcall_interactively):
12792 * minibuf.c (Fread_variable): Callers changed.
12794 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12796 * xdisp.c (set_cursor_from_row): If the display string appears in
12797 the buffer at position that is closer to point than the position
12798 after the display string, display the cursor on the first glyph of
12799 the display string. Fixes cursor display when a 'display' text
12800 property immediately follows invisible text. (Bug#11094)
12802 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12804 composite.c: use 'double' consistently
12805 * composite.c (get_composition_id): Use 'double' consistently
12806 instead of converting 'float' to 'double' and vice versa; this is
12807 easier to understand and avoids a GCC warning.
12809 2012-04-09 Glenn Morris <rgm@gnu.org>
12811 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12812 preparation for dumping it with emacs. (Bug#4789)

12833 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12834 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12835 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12836 objects, as mark_maybe_pointer will catch them otherwise.
12837 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12838 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12856 [!WINDOWSNT]: New macros.
12857 (init_libxml2_functions, libxml2_loaded_p): New functions.
12858 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12859 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12860 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12861 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12863 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12864 Call init_libxml2_functions before calling libxml2 functions.
12865 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12867 * emacs.c: Don't include libxml/parser.h.
12868 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12869 xmlCleanupParser directly.
12871 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12873 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12875 * indent.c (Fvertical_motion): If there is a display string at
12876 point, use it.vpos to compute how many lines to backtrack after

12879 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12881 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12882 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12883 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12884 macros related to unification of CJK characters. For the details,
12885 see the discussion following the message here:
12886 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12888 2012-04-04 Chong Yidong <cyd@gnu.org>
12890 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12892 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12894 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12895 instead of alloca. (Bug#11138)
12897 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

12902 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12904 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12905 position we get to after a call to move_it_to fails the
12906 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12907 only if we wind up in a string from display property. (Bug#11063)
12909 * window.c (Fdelete_other_windows_internal): Invalidate the row
12910 and column information about mouse highlight, so that redisplay
12911 restores it after reallocating the glyph matrices. (Bug#7464)
12913 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12914 string comes from a `display' text property, use the buffer
12915 position of that property as if we actually saw that position in
12917 (move_it_by_lines): Remove the assertion that
12918 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12919 violated when there's a before-string at the beginning of a line.
12922 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12924 * xdisp.c (append_space_for_newline): If the default face was
12925 remapped, use the remapped face for the appended newline.
12926 (extend_face_to_end_of_line): Use the remapped default face for
12927 extending the face to the end of the line.
12928 (display_line): Call extend_face_to_end_of_line when the default
12929 face was remapped. (Bug#11068)
12931 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12933 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

12937 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12939 2012-03-27 Glenn Morris <rgm@gnu.org>
12941 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12944 2012-03-26 Kenichi Handa <handa@m17n.org>

12951 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12952 (command_loop_1): Use it; inhibit selection update for
12953 handle-select-window too (Bug#8996).
12955 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12957 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12959 2012-03-25 Kenichi Handa <handa@m17n.org>
12961 * dispextern.h (struct glyph): Change the bit length of
12962 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12964 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12966 * s/ms-w32.h (tzname): Include time.h before redirecting to
12967 _tzname. Fixes the MSVC build. (Bug#9960)
12969 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12971 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12974 * xterm.c (XTread_socket): Only modify handling_signal if
12975 !SYNC_INPUT. (Bug#11080)
12977 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12979 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12980 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12981 when fetching a multibyte character consumes more bytes than
12982 CHAR_BYTES returns, due to unification of CJK characters in
12983 string_char. (Bug#11073)
12985 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12987 * process.c (wait_reading_process_output): Handle pty disconnect
12988 by refraining from sending oneself a SIGCHLD (bug#10933).

12996 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12997 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.

13011 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13012 to reflect default non-nil value of redisplay-dont-pause.
13014 2012-03-19 Kenichi Handa <handa@m17n.org>
13016 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13017 it fit in a valid range (Bug#11003).
13019 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13021 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13022 that is not from display property, accept the row as a "cursor
13023 row" if one of the string's character has a non-nil `cursor'
13024 property. Fixes cursor positioning when there are newlines in
13025 overlay strings, e.g. in icomplete.el. (Bug#11035)
13027 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13029 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13031 2012-03-12 Chong Yidong <cyd@gnu.org>
13033 * eval.c (inhibit_lisp_code): Rename from
13034 inhibit_window_configuration_change_hook; move from window.c.
13036 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13037 * window.c (run_window_configuration_change_hook)
13038 (syms_of_window): Callers changed.

13058 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13061 2012-03-03 Glenn Morris <rgm@gnu.org>
13063 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13065 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13067 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13068 position past the first glyph_row that ends at ZV. (Bug#10902)
13069 (redisplay_window, next_element_from_string): Fix typos in
13071 (redisplay_window): Pass to move_it_vertically the margin in
13072 pixels, not in screen lines.
13074 2012-03-02 Glenn Morris <rgm@gnu.org>
13076 * buffer.c (buffer-list-update-hook): Doc fix.
13078 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13080 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13081 push_it before setting up the iterator for the first overlay
13082 string, even if we have an empty string loaded.
13083 (next_overlay_string): If there's an empty string on the iterator
13084 stack, pop the stack. (Bug#10903)
13086 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13088 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13089 Suggested by Stefan Monnier in
13090 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13091 * alloc.c (widen_to_Lisp_Object): New static function.
13092 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13093 and widening them to Lisp_Objects. This would work even if
13094 USE_LSB_TAG is defined and wide integers are used, which might
13095 happen in a future version of Emacs.
13097 2012-02-25 Chong Yidong <cyd@gnu.org>
13099 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13102 * xselect.c (Fx_selection_exists_p): Doc fix.

13104 before saving to clipboard manager.
13106 2012-02-24 Chong Yidong <cyd@gnu.org>
13108 * keyboard.c (process_special_events): Handle all X selection
13109 requests in kbd_buffer, not just the next one (Bug#8869).

13136 when computing $valmask.
13138 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13139 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13140 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13141 It's useless in that case, and it can cause problems on hosts
13142 that allocate halves of EMACS_INT values separately.
13143 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13144 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13145 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13146 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13147 it avoids undefined behavior on hosts where shifting right by more
13148 than the word width has undefined behavior.
13150 2012-02-19 Chong Yidong <cyd@gnu.org>
13152 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13153 (Funhandled_file_name_directory, Ffile_name_as_directory)
13154 (Fdirectory_file_name, Fexpand_file_name)

13170 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13172 2012-02-15 Chong Yidong <cyd@gnu.org>
13174 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

13190 2012-02-12 Chong Yidong <cyd@gnu.org>
13192 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13193 as that creates a dangerous corner case.
13195 * window.c (Fdelete_window_internal): Invalidate the mouse
13196 highlight (Bug#9904).
13198 2012-02-12 Glenn Morris <rgm@gnu.org>

13201 (Fx_get_selection_internal, Fx_disown_selection_internal)
13202 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13203 * nsselect.m (Fx_own_selection_internal)
13204 (Fx_disown_selection_internal, Fx_selection_exists_p)
13205 (Fx_selection_owner_p, Fx_get_selection_internal):
13206 Sync docs and argument specs with the xselect.c versions.
13208 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13210 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

13228 2012-02-07 Chong Yidong <cyd@gnu.org>
13230 * buffer.c (Fbuffer_local_variables)
13231 (buffer_lisp_local_variables): Handle unbound vars correctly;
13232 don't let Qunbound leak into Lisp.
13234 2012-02-07 Glenn Morris <rgm@gnu.org>
13236 * image.c (Fimagemagick_types): Doc fix.
13238 * image.c (imagemagick-render-type): Change it from a lisp object
13239 to an integer. Move the doc here from the lisp manual.

13263 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13264 after rounding frame sizes. (Bug#9723)
13266 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13268 * keyboard.c (adjust_point_for_property): Don't position point
13269 before BEGV. (Bug#10696)
13271 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13273 Handle overflow when computing char display width (Bug#9496).
13274 * character.c (char_width): Return EMACS_INT, not int.
13275 (char_width, c_string_width): Check for overflow when
13276 computing the width; this is possible now that individual
13277 characters can have unbounded width. Problem introduced
13278 by merge from Emacs 23 on 2012-01-19.
13280 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13813 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13814 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13815 this macro definition.
13817 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

13842 * xdisp.c (redisplay_window): If cursor row is not fully visible
13843 after recentering, and scroll-conservatively is set to a large
13844 number, scroll window by a few more lines to make the cursor fully
13845 visible and out of scroll-margin. (Bug#10105)
13846 (start_display): Don't move to the next line if the display should
13847 start at a newline that is part of a display vector or an overlay
13848 string. (Bug#10119)

13928 Otherwise, valgrind does not work on some platforms.
13929 Problem reported by Andreas Schwab in
13930 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13931 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13932 is set, removing the need for VIRT_ADDRESS_VARIES.
13933 (PURE_P): Use a more-efficient implementation that needs just one
13934 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13935 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13936 to 4 (xorl, subq, cmpq, setbe).
13937 * alloc.c (pure): Always extern now, since that's the
13938 VIRT_ADDR_VARIES behavior.
13939 (PURE_POINTER_P): Use a single comparison, not two, for
13940 consistency with the new puresize.h.
13941 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13942 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13948 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13949 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13950 behave as if the cursor position were at the window margin.
13952 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13953 and the cursor position is out of bounds, behave as if the cursor
13954 position were at the window margin. (Bug#10075)
13956 2011-11-18 Chong Yidong <cyd@gnu.org>
13958 * window.c (Fwindow_combination_limit): Make first argument

13976 hash values of the two rows. (Bug#10035)
13977 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13979 * xdisp.c (row_hash): New function, body extracted from
13980 compute_line_metrics.
13981 (compute_line_metrics): Call row_hash, instead of computing the
13984 * dispnew.c (verify_row_hash): Call row_hash for computing the
13985 hash code of a row, instead of duplicating code from xdisp.c.
13987 * dispextern.h (row_hash): Add prototype.
13989 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13991 * frame.c (delete_frame): Don't delete the terminal when the last

14016 (recombine_windows, make_parent_window, make_window)
14017 (Fsplit_window_internal, saved_window)
14018 (Fset_window_configuration, save_window_save): Rename all
14019 occurrences of window_nest to window_combination_limit.
14021 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
14023 * image.c (imagemagick_load_image): Fix typo.
14025 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14027 * xdisp.c (display_line): Move the call to
14028 highlight_trailing_whitespace before the call to
14029 compute_line_metrics, since the latter needs to see the final
14030 faces of all the glyphs to compute ROW's hash value.
14031 Fixes assertion violations in row_equal_p. (Bug#10035)
14033 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14035 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14036 just return (bug#10044).
14038 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14040 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14041 with user-defined heap size. Bump the default size of the temacs
14042 heap to 27MB, to avoid memory warning when running temacs.
14043 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
14045 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14046 current_matrix and desired_matrix. (Bug#9990)
14047 (verify_row_hash) [XASSERTS]: New function.
14048 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
14049 that the hash value of glyph rows is correct.

14081 avoid a crash (bug#9496).
14083 2011-11-09 Chong Yidong <cyd@gnu.org>
14085 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

14092 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14094 Avoid some portability problems by eschewing 'extern inline' functions.
14095 The trivial performance wins aren't worth the portability hassles; see
14096 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14098 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14099 (window_box_width, window_box_left, window_box_left_offset)
14100 (window_box_right, window_box_right_offset): Undo previous change,
14101 by removing the "extern"s.
14102 * intervals.c (adjust_intervals_for_insertion)
14103 (adjust_intervals_for_deletion): Undo previous change,
14104 making these static again.
14105 (offset_intervals, temp_set_point_both, temp_set_point)
14106 (copy_intervals_to_string): No longer inline.
14107 * xdisp.c (window_text_bottom_y, window_box_width)

14147 This is also needed for porting to any host where GC_MARK_STACK is
14148 not GC_MAKE_GCPROS_NOOPS.
14149 (which_symbols): Use it.
14151 2011-11-07 Kenichi Handa <handa@m17n.org>
14153 * coding.c (coding_set_destination): Check coding->src_pos only

14164 * xmenu.c (cleanup_widget_value_tree): New function.
14165 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14166 calling free_menubar_widget_value_tree directly (Bug#9830).
14168 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14170 Fix some portability problems with 'inline'.
14171 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14172 (window_box_width, window_box_left, window_box_left_offset)
14173 (window_box_right, window_box_right_offset): Declare extern.
14174 Otherwise, these inline functions do not conform to C99 and
14175 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14176 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14177 * intervals.c (adjust_intervals_for_insertion)
14178 (adjust_intervals_for_deletion): Now extern, because otherwise the
14179 extern inline functions 'offset_intervals' couldn't refer to it.
14180 (static_offset_intervals): Remove.
14181 (offset_intervals): Rewrite using the old contents of
14182 static_offset_intervals. The old version didn't conform to C99
14183 because an extern inline function contained a reference to an
14184 identifier with static linkage.

14206 (Fwindow_vscroll): Doc fix.
14207 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14208 argument, since it makes no sense to pass a live window and for

14291 previous/next-single-property-change returns nil, treat that as
14292 the beginning or the end of the buffer. (Bug#9955)
14294 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14296 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
14297 label is not null (Bug#9951).
14298 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl

14319 (mouse_face_from_buffer_pos, note_mouse_highlight):
14320 Rename cover_string to disp_string.

14330 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14331 past the beginning of the current glyph matrix.
14333 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14335 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14336 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

14356 so that this new function doesn't get optimized away by a

14379 2011-10-29 Glenn Morris <rgm@gnu.org>
14381 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14382 Not clear what it was for, and it causes various bugs. (Bug#9839)
14384 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14386 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14387 possible random value that matches one of those tested as
14388 condition to clear the mouse face.
14390 2011-10-28 Chong Yidong <cyd@gnu.org>

14406 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14408 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14409 <oslsachem@gmail.com> for helping to debug this.
14411 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

14417 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14419 (w32font_open_internal, compute_metrics):
14420 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14421 instead of calling the "wide" APIs directly.
14423 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14425 * w32.h (syms_of_w32font): Add prototype.
14427 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14429 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14430 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14431 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14432 (Fmove_to_window_line): Doc fix.
14434 2011-10-27 Chong Yidong <cyd@gnu.org>
14436 * process.c (make_process): Set gnutls_state to NULL.
14438 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14439 non-NULL, regardless of GNUTLS_INITSTAGE.
14440 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14441 an error. Set process slots as soon as we allocate them.
14443 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14445 2011-10-27 Chong Yidong <cyd@gnu.org>
14447 * gnutls.c (emacs_gnutls_deinit): New function.

14452 (deactivate_process): Call emacs_gnutls_deinit.
14454 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14456 * image.c (x_create_x_image_and_pixmap):
14457 * w32.c (sys_rename, w32_delayed_load):
14458 * w32font.c (fill_in_logfont):

14464 extracted from Fw32_default_color_map.
14465 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14467 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14469 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14471 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14473 * keyboard.c (test_undefined): New function (bug#9751).
14474 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14476 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14478 * sysdep.c (init_sys_modes): Fix the check for the controlling
14479 terminal (Bug#6649).
14481 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14483 * dispextern.h (struct bidi_it): New member next_en_type.
14485 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14486 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14487 current character, check also for next_en_type being WEAK_EN.
14488 (bidi_resolve_weak): Don't enter the expensive loop if the current
14489 position is before next_en_pos. Record the bidi type of the first
14490 non-ET, non-BN character we find, in addition to its position.
14491 (bidi_level_of_next_char): Invalidate next_en_type when
14492 next_en_pos is over-stepped.
14494 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14496 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14497 * editfns.c: Rewrite current-time-zone so that it invokes
14498 the equivalent of (format-time-string "%Z") to get the time zone name.
14499 This fixes a bug when the time zone name contains characters that
14500 need converting from the system time locale to Emacs internal format.
14501 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14502 that patch fixed format-time-string to do the conversion, but
14503 I forgot to fix current-time-zone.
14504 (format_time_string): New function, containing most of
14505 what Fformat_time_string used to contain.
14506 (Fformat_time_string): Rewrite in terms of format_time_string.
14507 This doesn't change this function's behavior.
14508 (current-time-zone): Rewrite to use format_time_string.
14509 This fixes the bug reported by Michael Schierl in
14510 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14511 Jason Rumney's 2007-06-07 change worked around this bug, but
14513 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14515 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14517 * xdisp.c (start_display): If the character at POS is displayed
14518 via a display vector, reset IT->current.dpvec_index to zero.
14519 (try_window_reusing_current_matrix): If a line ends in a display
14520 vector or the next line starts in a display vector, continue
14521 redrawing the window even though the character position of
14522 start_row was reached.
14525 2011-10-18 Chong Yidong <cyd@gnu.org>
14527 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14528 with nobreak-char-display too.
14530 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14532 Fix part 3 of bug#9771.
14533 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14534 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14535 non-neutral characters if the current character is a paragraph
14536 separator (a.k.a. Newline). This avoids running the same
14537 expensive loop twice, once when we consume the preceding newline
14538 and the other time when the line actually needs to be displayed.
14539 Avoid the loop when we see neutrals on the base embedding level
14540 following a character whose directionality is the same as the
14541 paragraph's. This avoids running the expensive loop when a line
14542 ends in a long sequence of neutrals, like control characters.
14543 Add assertion against STRONG_AL type. Slightly rearrange code
14544 that determines the type of a neutral given the first non-neutral
14546 (bidi_level_of_next_char): Set next_en_pos to zero when
14547 invalidating its info.
14549 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14551 * xdisp.c (push_display_prop): Determine whether to record string
14552 or buffer position by IT->string, not by IT->method. Allow
14553 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14554 (move_it_vertically_backward): Don't look for character position
14555 immediately after the newline when in a continuation line.
14558 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14560 * window.c (coordinates_in_window): Rewrite and delabelize
14561 vertical border check. (Bug#5357) (Bug#9618)
14563 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14565 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14566 errors in XSetWindowBorder (bug#9310).
14568 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14570 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14571 avoid crash when xmalloc overrun checking is enabled.
14573 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14575 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14576 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14577 cursor motion with <left> and <right> arrow keys.
14579 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14580 some callers set that themselves.
14582 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14584 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14585 display string and the previous row comes from the same string and
14586 is empty. (Bug#9739) (Bug#9738)
14588 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14590 * doc.c (get_doc_string): Encode file name (bug#9735).
14592 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14594 * bidi.c (bidi_level_of_next_char):
14595 * xdisp.c (get_visually_first_element): Remove old incorrect
14596 comments regarding the Unicode Line Separator character.
14598 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14600 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14602 * alloc.c (Fgc_status): Do not access beyond zombies array
14603 boundary if nzombies > MAX_ZOMBIES.
14604 * alloc.c (dump_zombies): Add missing format specifier.
14606 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14608 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14609 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14611 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14612 Some packages use them to denote characters with modifiers.
14614 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14616 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14617 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14618 matching a pp-number. Rename parameter var to var1.
14620 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14622 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14624 2011-10-08 Glenn Morris <rgm@gnu.org>
14626 * callint.c (Fcall_interactively): Give a more explicit error for the
14627 'c' case with a non-character input. (Bug#8479)
14629 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14631 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14633 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14634 lines that are hscrolled on the left.
14636 * dispnew.c (buffer_posn_from_coords): Account for a possible
14637 presence of header-line. (Bug#4426)
14639 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14641 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14642 Don't advertise functionality which we discourage or doesn't work.
14644 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14646 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14647 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14648 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14649 this makes Emacs dump core during garbage collection on rare
14650 occasions. sizeof is obviously inferior to offsetof here, so
14651 stick with offsetof.
14652 (GC_POINTER_ALIGNMENT): New macro.
14653 (mark_memory): Omit 3rd (offset) arg; caller changed.
14654 Don't assume EMACS_INT alignment is the same as pointer alignment.
14656 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14658 * keyboard.c (read_key_sequence_remapped): New var.
14659 (read_key_sequence): Compute remapping in the right buffer.
14660 (command_loop_1): Use read_key_sequence's remapping directly.
14662 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14664 * dired.c (file_name_completion): Don't expand file name.
14665 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14666 before checking file name handler.
14668 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14669 they've been requested explicitly (bug#9591).
14671 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14673 * keymap.c (Fsingle_key_description): Use make_specified_string
14674 instead of build_string to build string from push_key_description.
14677 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14679 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14680 This fixes a Y2038 bug on 64-bit hosts.
14681 * buffer.c (reset_buffer):
14682 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14683 (Fclear_buffer_auto_save_failure):
14684 Use 0, not -1, to represent an unset failure time, since time_t
14685 might not be signed.
14687 Remove dependency on glibc malloc internals.
14688 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14689 Move back here from lisp.h, but with their new implementations.
14690 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14691 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14692 * charset.c (charset_table_init): New static var.
14693 (syms_of_charset): Use it instead of xmalloc. This removes a
14694 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14695 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14696 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14697 Move back to alloc.c.
14698 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14699 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14701 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14703 * nsterm.m (windowDidResize): Call x_set_window_size only when
14704 ns_in_resize is true. Otherwise set pixelwidth/height and
14705 call change_frame_size (Bug#9628).
14707 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14709 Port --enable-checking=all to Fedora 14 x86-64.
14710 * charset.c (syms_of_charset): Also account for glibc malloc's
14711 internal overhead when calculating the initial malloc maximum.
14713 Port --enable-checking=all to Fedora 14 x86.
14714 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14716 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14717 (overrun_check_realloc, overrun_check_free):
14718 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14719 That way, xmalloc returns a properly-aligned pointer even if
14720 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14721 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14722 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14723 into account when calculating the initial malloc maximum.
14724 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14725 Move here from alloc.c, so that charset.c can use it too.
14726 Properly align; the old code wasn't right for common 32-bit hosts
14727 when configured with --enable-checking=all.
14728 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14729 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14731 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14733 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14736 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14738 * xdisp.c (compute_display_string_end): If there's no display
14739 string at CHARPOS, return -1.
14741 * bidi.c (bidi_fetch_char): When compute_display_string_end
14742 returns a negative value, treat the character as a normal
14743 character not covered by a display string. (Bug#9624)
14745 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14747 * lread.c (Fread_from_string): Fix typo in docstring.
14749 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14751 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14752 newline, reseat the iterator instead of bidi-iterating there one
14753 character at a time. (Bug#9610)
14754 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14755 TO_CHARPOS if the bidi iterator is at base embedding level.
14757 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14759 * lread.c (readevalloop): Use correct code for NBSP.
14760 (read1): Likewise. (Bug#9608)
14762 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14764 * dbusbind.c (Fdbus_register_signal): When service is not
14765 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14767 2011-09-25 Glenn Morris <rgm@gnu.org>
14769 * buffer.c (truncate-lines): Doc fix.
14771 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14773 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14774 (Fset_window_next_buffers): Doc fix.
14776 2011-09-24 Glenn Morris <rgm@gnu.org>
14778 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14780 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14782 Fix minor problems found by static checking.
14783 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14784 * indent.c (Fvertical_motion): Fix == vs = typo.
14786 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14788 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14789 Default value is now t. Doc fix.
14791 * indent.c (Fvertical_motion): Compute and apply the overshoot
14792 logic when moving up, not only when moving down. Fix the
14793 confusing name and values of the it_overshoot_expected variable;
14794 logic changes accordingly. (Bug#9254) (Bug#9549)
14796 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14797 CHARPOS is covered by a display string which includes newlines.
14798 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14799 is covered by a display string with embedded newlines.
14801 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14803 * dbusbind.c (Fdbus_register_signal): Add match rule to
14804 Vdbus_registered_objects_table. (Bug#9581)
14805 (Fdbus_register_method, Vdbus_registered_objects_table):
14808 2011-09-24 Jim Meyering <meyering@redhat.com>
14810 do not ignore write error for any output size
14811 The previous change was incomplete.
14812 While it makes emacs --batch detect the vast majority of stdout
14813 write failures, errors were still ignored whenever the output size is
14814 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14815 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14816 && echo FAIL: ignored write error
14817 FAIL: ignored write error
14818 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14819 && echo FAIL: ignored write error
14820 FAIL: ignored write error
14821 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14823 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14825 * emacs.c (Fkill_emacs): In noninteractive mode exit
14826 non-successfully if a write error occurred on stdout. (Bug#9574)
14828 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14830 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14833 * dispextern.h (struct it): Update the comment documenting what
14836 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14838 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14839 a display string, extend search for cursor position to end of row.
14840 (find_row_edges): If the row ends in a newline from a display
14841 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14842 Handle the case of a display string with multiple newlines.
14843 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14844 non-empty line. Fixes confusing cursor motion with arrow keys at
14845 the beginning of a line that starts with whitespace.
14847 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14849 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14852 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14854 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14855 boolean (Bug#9154).
14857 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14859 * xdisp.c (display_line): Record maximum and minimum buffer
14860 positions even if no glyphs were produced (e.g., by a zero-width
14861 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14862 buffer positions that will be removed from the glyph row because
14864 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14865 column is beyond frame width: don't subtract 1 "pixel" when
14866 computing width of the stretch.
14867 (reseat_at_next_visible_line_start): Undo the change made on
14868 2011-09-17 that saved paragraph information and restored it after
14869 the call to `reseat'. (Bug#9545)
14871 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14873 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14874 and turn window cursor on if cleared (Bug#9415).
14876 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14878 * search.c (boyer_moore): Take unibyte characters from pattern
14879 literally. (Bug#9458)
14881 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14883 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14885 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14887 Fix minor problem found by static checking.
14888 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14889 initialized, to pacify gcc -Wuninitialized.
14891 * fileio.c: Report proper errno when syscall falls.
14892 (Finsert_file_contents): Save and restore errno,
14893 so that report_file_error outputs the correct diagnostic.
14894 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14896 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14898 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14900 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14902 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14903 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14905 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14907 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14908 about the current paragraph and restore it after the call to reseat.
14910 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14911 (bidi_find_paragraph_start): Search back for paragraph beginning
14912 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14913 (bidi_move_to_visually_next): Only trigger paragraph-related
14914 computations when the last character is a newline or at EOB, not
14915 just any NEUTRAL_B. (Bug#9470)
14917 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14918 truncated lines if point is covered by a display string. (Bug#9524)
14920 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14922 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14923 (cons_to_x_long): New function.
14924 (lisp_data_to_selection_data): Use it. Correct the test for
14925 short-versus-long data; it was negated. Break out of vector
14926 loop, for efficiency, when a long datum is discovered.
14928 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14930 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14932 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14934 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14935 GCC PR/17406) by declaring this function with external scope.
14937 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14939 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14940 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14942 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14944 * editfns.c (Fformat): Correctly handle text properties on "%%".

14952 * xdisp.c (get_next_display_element)
14953 (fill_composite_glyph_string): Add comments about special meaning
14954 of TAB characters in a composition.
14956 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14958 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14959 This occurs when processing a multibyte format.
14960 Problem reported by Wolfgang Jenker.
14962 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14964 * xdisp.c (try_cursor_movement): Only check for exact match if
14965 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14967 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14969 Remove unused external symbols.
14970 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14971 * xdisp.c (calc_pixel_width_or_height): Now static.
14972 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14973 * indent.c (check_display_width):
14974 * w32term.c: Fix comment to match code.
14975 * xterm.c, xterm.h (x_catching_errors): Remove.
14977 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14979 * xselect.c: Use signed conversions more consistently (Bug#9498).
14980 (selection_data_to_lisp_data): Assume incoming selection data are
14981 signed integers, not unsigned. This is to be consistent with
14982 outgoing selection data, which was modified to use signed integers
14983 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14984 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14985 expects long, not unsigned long.
14987 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14989 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14990 computation of loop end. Reported by Johan Bockgård
14993 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14995 * frame.c (Fother_visible_frames_p): Function deleted.
14997 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14999 * indent.c (compute_motion): Process display vector front to back
15000 rather than the other way around. (Bug#2496)
15002 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15004 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15006 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15008 * minibuf.c (Fread_from_minibuffer): Doc fix.
15010 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15012 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15013 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15015 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15017 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15018 value for non-existent files.
15020 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15022 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15023 set its "size" to -1. This will set the modtime_size field of
15024 the corresponding buffer to -1, which is what
15025 verify-visited-file-modtime expects for files that do not exist.
15028 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15030 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15032 * lisp.h: ... from here. push_key_description is no longer
15033 defined in keyboard.c, so its declaration should not be in
15034 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15035 logically belongs with push_key_description.
15037 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15039 * buffer.h: Include <sys/types.h> instead of <time.h>.
15040 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15041 Problem reported by Herbert J. Skuhra.
15043 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15045 * xml.c (parse_region): Make the parsing work for
15046 non-comment-starting XML files again (bug#9144).
15048 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15050 * image.c (gif_load): Fix calculation of bottom and right corner.
15053 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15055 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15056 redisplay in small windows.
15058 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15060 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15062 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15064 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15065 Operate on live windows only.
15067 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15069 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15071 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15073 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15074 only under bidi iteration.
15076 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15078 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15080 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15082 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15083 Without this fix, the command to link temacs failed due to an
15084 undefined symbol __builtin_isnan. This is because
15085 /usr/include/iso/math_c99.h #defines isnan(x) to
15086 __builtin_isnan(x), but the bundled gcc, which identifies itself
15087 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15089 * floatfns.c (isnan): #undef, and then #define to a clone of
15091 (Fisnan): Always define, since it's always available now.
15092 (syms_of_floatfns): Always define isnan at the Lisp level.
15094 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15096 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15098 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15100 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15101 The previous code assumed that file offsets (off_t values) fit in
15102 EMACS_INT variables, which is not true on typical 32-bit hosts.
15103 The code messed up by falsely reporting buffer overflow in cases
15104 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15105 when "big" contains more than 2**29 bytes, even though this
15106 inserts just one byte and does not overflow the buffer.
15107 (Finsert_file_contents): Store file offsets as off_t
15108 values, not as EMACS_INT values. Check for overflow when
15109 converting between EMACS_INT and off_t. When checking for
15110 buffer overflow or for overlap, take the offsets into account.
15111 Don't use EMACS_INT for small values where int suffices.
15112 When checking for overlap, fix a typo: ZV was used where
15113 ZV_BYTE was intended.
15114 (Fwrite_region): Don't assume off_t fits into 'long'.
15115 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15117 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15119 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15121 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15123 sprintf-related integer and memory overflow issues (Bug#9412).
15125 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15126 (esprintf, exprintf, evxprintf): New functions.
15127 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15128 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15129 (modify_event_symbol): Do not assume that the length of
15130 name_alist_or_stem is safe to alloca and fits in int.
15131 (Fexecute_extended_command): Likewise for function name and binding.
15132 (Frecursion_depth): Wrap around reliably on integer overflow.
15133 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15134 since some callers pass EMACS_INT values.
15135 (Fsingle_key_description): Don't crash if symbol name contains more
15136 than MAX_ALLOCA bytes.
15137 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15138 (get_minibuffer): Arg is now EMACS_INT, not int.
15139 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15140 (esprintf, exprintf, evxprintf): New decls.
15141 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15143 * dbusbind.c (signature_cat): New function.
15144 (xd_signature, Fdbus_register_signal):
15145 Do not overrun buffer; instead, report string overflow.
15147 * dispnew.c (add_window_display_history): Don't overrun buffer.
15148 Truncate instead; this is OK since it's just a log.
15150 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15151 even if the time zone offset is outlandishly large.
15152 Don't mishandle offset == INT_MIN.
15154 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15155 when creating daemon; the previous buffer-overflow check was incorrect.
15157 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15158 which has the guts of the old verror function.
15160 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15161 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15163 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15164 (font_unparse_xlfd): Don't blindly alloca long strings.
15165 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15166 fits in int, when using sprintf. Use single snprintf to count
15167 length of string rather than counting it via multiple sprintfs;
15168 that's simpler and more reliable.
15169 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15170 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15171 sprintf, in case result does not fit in int.
15173 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15174 (fontset_from_font): Print it.
15176 * frame.c (tty_frame_count): Now printmax_t, not int.
15177 (make_terminal_frame, set_term_frame_name): Print it.
15178 (x_report_frame_params): In X, window IDs are unsigned long,
15179 not signed long, so print them as unsigned.
15180 (validate_x_resource_name): Check for implausibly long names,
15181 and don't assume name length fits in 'int'.
15182 (x_get_resource_string): Don't blindly alloca invocation name;
15183 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15186 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15187 (xg_check_special_colors, xg_set_geometry):
15188 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15190 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15191 Use esprintf, not sprintf, in case result does not fit in int.
15193 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15194 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15195 it as a large positive number.
15196 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15197 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15199 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15200 in case result does not fit in int.
15202 * print.c (float_to_string): Detect width overflow more reliably.
15203 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15204 buffer overrun. Don't assume list length fits in 'int'. Treat
15205 print length of 0 as 0, not as infinity; to be consistent with other
15206 uses of print length in this function. Don't overflow print length
15207 index. Don't assume hash table size fits in 'long', or that
15208 vectorlike size fits in 'unsigned long'.
15210 * process.c (make_process): Use printmax_t, not int, to format
15211 process-name gensyms.
15213 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15215 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15216 to avoid potential buffer overrun.
15218 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15219 if X resource line is longer than 512 bytes.
15221 * xfns.c (x_window): Make sprintf buffer a bit bigger
15222 to avoid potential buffer overrun.
15224 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15226 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15228 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15230 Integer overflow fixes for scrolling, etc.
15231 Without these, Emacs silently mishandles large integers sometimes.
15232 For example, "C-u 4294967297 M-x recenter" was treated as if
15233 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15235 * xdisp.c (try_window_id): Check Emacs fixnum range before
15236 converting to 'int'.
15238 * window.c (window_scroll_line_based, Frecenter):
15239 Check that an Emacs fixnum is in range before assigning it to 'int'.
15240 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15241 values converted from Emacs fixnums.
15242 (Frecenter): Don't wrap around a line count if it is out of 'int'
15243 range; instead, treat it as an extreme value.
15244 (Fset_window_configuration, compare_window_configurations):
15245 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15247 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15248 that can exceed INT_MAX. Check that EMACS_INT value is in range
15249 before assigning it to the (possibly-narrower) index.
15250 (match_limit): Don't assume that a fixnum can fit in 'int'.
15252 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15255 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15256 (Fvertical_motion): Don't wrap around LINES values that don't fit
15257 in 'int'. Instead, treat them as extreme values. This is good
15258 enough for windows, which can't have more than INT_MAX lines anyway.
15260 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15262 * Require libxml/parser.h to avoid compilation warning.
15264 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15266 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15267 since this reportedly can destroy thread storage.
15269 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15271 * syntax.c (find_defun_start): Update all cache variables if
15272 exiting early (Bug#9401).
15274 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15276 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15278 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15279 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15280 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15282 * term.c (tty_append_glyph): New function.
15283 (produce_stretch_glyph): Static function and its prototype deleted.
15285 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15288 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15290 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15291 when checking :margin (Bug#9390).
15292 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15293 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15294 so that the name doesn't mislead. All uses changed.
15296 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15298 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15301 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15303 * xdisp.c (move_it_to): Don't bail out early when reaching
15304 position beyond to_charpos, if we are scanning backwards.
15305 (move_it_vertically_backward): When DY == 0, make sure we get to
15306 the first character in the line after the newline.
15308 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15310 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15311 (ccl_driver): Do not generate an out-of-range pointer.
15312 (Fccl_execute_on_string): Remove unnecessary check for
15313 integer overflow, noted by Stefan Monnier in
15314 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15315 Remove a FIXME that didn't need fixing.
15316 Simplify the newly-introduced buffer reallocation code.
15318 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15320 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15322 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15324 Integer and memory overflow issues (Bug#9196).
15326 * doc.c (get_doc_string): Rework so that
15327 get_doc_string_buffer_size is the actual buffer size, rather than
15328 being 1 less than the actual buffer size; this makes xpalloc more
15331 * image.c (x_allocate_bitmap_record, cache_image):
15332 * xselect.c (Fx_register_dnd_atom):
15333 Simplify previous changes by using xpalloc.
15335 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15336 since either will do and ptrdiff_t is convenient with xpalloc.
15338 * charset.c (charset_table_size)
15339 (struct charset_sort_data.priority): Now ptrdiff_t.
15340 (charset_compare): Don't overflow if priorities differ greatly.
15341 (Fsort_charsets): Don't assume list length fits in int.
15342 Check for size-calculation overflow when allocating sort data.
15343 (syms_of_charset): Allocate an initial charset table that is
15344 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15346 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15348 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15349 The actual value is always <= INT_MAX, and leaving it unsigned made
15350 overflow checking harder.
15352 * dispextern.h (struct glyph_matrix.rows_allocated)
15353 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15354 with xpalloc. The values are still always <= INT_MAX.
15356 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15358 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15359 (SAFE_NALLOCA): New macro.
15361 * region-cache.c (struct boundary.pos, find_cache_boundary)
15362 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15363 (set_cache_region, invalidate_region_cache)
15364 (revalidate_region_cache, know_region_cache, region_cache_forward)
15365 (region_cache_backward, pp_cache):
15366 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15367 so that ptrdiff_t * can be passed to xpalloc.
15368 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15369 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15370 (pp_cache): Don't assume cache_len fits in int.
15371 * region-cache.h: Adjust extern decls to match.
15373 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15374 EMACS_INT, since either will do, for xpalloc.
15376 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15377 (xnmalloc, xnrealloc, xpalloc): New functions.
15379 * bidi.c (bidi_shelve_header_size): New constant.
15380 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15381 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15383 * bidi.c (bidi_cache_shrink):
15384 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15386 Don't update size of array until after memory allocation succeeds,
15387 because xmalloc/xrealloc may not return.
15388 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15389 now that we have proper integer overflow checking.
15390 (record_overlay_string, overlay_strings): Catch overflows when
15391 calculating size of overlay_str_buf.
15393 * callproc.c (Fcall_process): Check for size overflow when
15394 calculating size of args2.
15395 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15396 Normally we prefer signed values, but sticking with ptrdiff_t would
15397 require adding more-complicated checks.
15399 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15400 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15401 Redo buffer-overflow calculations to avoid integer overflow.
15402 Add a FIXME comment where memory seems to be over-allocated.
15404 * character.c (Fstring): Check for size-calculation overflow.
15406 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15407 unnecessary integer overflow. Check for size overflow.
15408 (encode_coding_object): Don't update size until xmalloc succeeds.
15410 * composite.c (get_composition_id): Check for overflow in glyph
15411 length calculations.
15413 Integer and memory overflow fixes for display code.
15414 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15415 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15416 (scrolling_window): Check for overflow in size calculations.

15424 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15425 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15428 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15429 (get_doc_string): Check for size calculation overflow.
15430 Don't update size until allocation succeeds.
15431 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15432 EMACS_INT, where ptrdiff_t will do.
15433 (Fsubstitute_command_keys): Check for string overflow.
15435 * editfns.c (set_time_zone_rule): Don't assume environment length
15437 (message_length): Now ptrdiff_t, not int.
15438 (Fmessage_box): Don't update size until allocation succeeds.
15439 Don't assume message length fits in int.
15440 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15442 * emacs.c (main): Do not reallocate argv, since there is a null at
15443 the end that can be overwritten, and this way there's no need to
15444 worry about size-calculation overflow.
15445 (sort_args): Check for size-calculation overflow.
15447 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15449 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15451 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15452 (x_set_scroll_bar_width, x_figure_window_size):
15453 Check for integer overflow.
15454 (x_set_alpha): Do not assume XINT fits in int.
15456 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15457 This is for the members text_lines, text_cols, total_lines, total_cols,
15458 where the system imposes an 'int' limit.
15460 * fringe.c (Fdefine_fringe_bitmap):
15461 Don't update size until alloc works.
15463 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15464 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15466 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15467 Check for size-calculation overflow.
15468 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15469 do, as we prefer signed integers.
15470 (id_to_widget.max_size, id_to_widget.used)
15471 (xg_store_widget_in_map, xg_remove_widget_from_map)
15472 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15473 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15474 Use and return ptrdiff_t, not int.
15475 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15476 * gtkutil.h: Change prototypes to match the above.
15478 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15479 are duplicate now that they've been promoted to lisp.h.
15480 (x_allocate_bitmap_record, x_alloc_image_color)
15481 (make_image_cache, cache_image, xpm_load):
15482 Don't update size until alloc is done.

15492 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15493 Use ptrdiff_t, not int, to count maps.
15494 (read_char_minibuf_menu_prompt): Check for overflow in size
15495 calculations. Don't update size until allocation succeeds.
15496 Redo calculations to avoid overflow.
15497 * keyboard.h: Change prototypes to match the above.
15499 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15501 (current_minor_maps): Check for size calculation overflow.
15502 * keymap.h: Change prototypes to match the above.
15504 * lread.c (read1, init_obarray): Don't update size until alloc done.
15506 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15525 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15526 for command line length. Do not attempt to address one before the
15527 beginning of an array, as that's not portable.
15529 * term.c (max_frame_lines): Remove; unused.
15530 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15532 (encode_terminal_code, calculate_costs): Check for size
15533 calculation overflow.

15555 Use ptrdiff_t, not int, for sizes.
15556 (Finternal_make_lisp_face, cache_face):
15557 Check for size calculation overflow.
15558 (cache_face): Treat size calculation overflows as if they were
15559 memory exhaustion (the usual treatment), rather than aborting.
15561 * xfns.c (x_encode_text, x_set_name_internal)
15562 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15563 sizes, since they can exceed INT_MAX in size. Check for size
15564 calculation overflow.
15566 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15567 (xg_select): Check for size calculation overflow.
15568 Don't update size until alloc done.
15570 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15571 as sprintf is limited to int lengths.
15573 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15574 (X_LONG_MIN): New macros.
15575 Use them to make the following changes clearer.
15576 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15577 This change doesn't affect the value now, but it may help remind
15578 future maintainers not to raise the value too much later.
15579 (SELECTION_QUANTUM): Remove, replacing with ...
15580 (selection_quantum): ... new function, which avoids overflow.
15582 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15583 assumption that selection length fits in 'int'.

15587 (lisp_data_to_selection_data, clean_local_selection_data):
15588 Use ptrdiff_t, not int, to record length of selection.
15589 (x_reply_selection_request, x_get_window_property)
15590 (receive_incremental_selection, x_property_data_to_lisp):
15591 Redo calculations to avoid overflow.
15592 (x_reply_selection_request): When sending hint, ceiling it at
15593 X_LONG_MAX rather than relying on wraparound overflow to send
15595 (x_get_window_property, receive_incremental_selection)
15596 (lisp_data_to_selection_data, x_property_data_to_lisp):
15597 Check for size-calculation overflow.
15598 (x_get_window_property, receive_incremental_selection)

15600 Don't store size until memory allocation succeeds.
15601 (x_get_window_property): Plug memory leak on memory exhaustion.
15602 Don't double-block input; malloc is safe here. Don't assume 2**34
15603 - 4 fits in unsigned long. Add an xassert to check
15604 XGetWindowProperty overflow. Be more careful about overflow
15605 calculations, and distinguish size from memory overflow better.
15606 (receive_incremental_selection): When tracing, don't assume
15607 unsigned int is less than INT_MAX.
15608 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15609 harmful) conversions of unsigned short to int.
15610 (lisp_data_to_selection_data): Don't assume that integers
15611 in the range -65535 through -1 fit in an X unsigned short.
15612 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15613 result parameters unless successful. Rely on cons_to_unsigned
15614 to report problems with elements; the old code wasn't right anyway.
15615 (x_check_property_data): Check for int overflow; we cannot use
15616 a wider type due to X limits.
15617 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15619 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15621 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15622 (x_term_init): Check for size calculation overflow.
15623 (x_color_cells): Don't store size until memory allocation succeeds.
15624 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15625 Don't assume alloca size is less than MAX_ALLOCA.
15626 (x_term_init): Don't assume length fits in int (sprintf is limited
15629 Use ptrdiff_t for composition IDs.
15630 * character.c (lisp_string_width):
15631 * composite.c (composition_table_size, n_compositions)
15632 (get_composition_id, composition_gstring_from_id):

15648 * image.c (xpm_get_color_table_h):
15649 * lisp.h (hash_lookup, hash_put):
15650 * minibuf.c (Ftest_completion):
15651 Use ptrdiff_t for hash table indexes, not int (which is too
15652 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15653 32-bit --with-wide-int hosts).
15655 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15656 Add a FIXME comment about memory leaks.
15657 (syms_of_charset): Don't assume xmalloc returns.

15661 * character.h (CHAR_WIDTH):
15662 * indent.c (MULTIBYTE_BYTES_WIDTH):
15663 Use sanitize_char_width to avoid undefined and/or bad behavior
15664 with outlandish widths.
15665 * character.h (sanitize_tab_width): Rename from sanitize_width,
15666 now that we have two such functions. All uses changed.
15667 (sanitize_char_width): New inline function.
15669 Don't assume that tab-width fits in int.
15670 * character.h (sanitize_width): New inline function.
15671 (SANE_TAB_WIDTH): New macro.
15672 (ASCII_CHAR_WIDTH): Use it.
15673 * indent.c (sane_tab_width): Remove. All uses replaced by
15674 SANE_TAB_WIDTH (current_buffer).

15677 * fileio.c: Integer overflow issues with file modes.
15678 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15680 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15681 Remove unreachable code.
15682 (read_hex, load_charset_map_from_file): Check for integer overflow.
15684 * xterm.c: Don't go over XClientMessageEvent limit.
15685 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15686 (x_send_scroll_bar_event): Likewise. Check that the size does not
15687 exceed limits imposed by XClientMessageEvent, as well as the usual
15688 ptrdiff_t and size_t limits.
15690 * keyboard.c: Overflow, signedness and related fixes.
15691 (make_lispy_movement): Use same integer type in forward decl
15692 that is used in the definition.
15693 (read_key_sequence, keyremap_step):
15694 Change bufsize argument back to int, undoing my 2011-03-30 change.
15695 We prefer signed types, and int is wide enough here.
15696 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15697 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15698 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15699 length, not size_t. Use ptrdiff_t for index, not int.
15700 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15701 possibility of integer overflow.
15703 Overflow, signedness and related fixes for images.
15705 * dispextern.h (struct it.stack[0].u.image.image_id)

15713 * xdisp.c (calc_pixel_width_or_height):
15714 * xfns.c (image_cache_refcount):
15715 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

15724 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15725 (lookup_image): Remove unnecessary tests.
15726 (xbm_image_p): Locals are now of int, not EMACS_INT,
15727 since parse_image_check makes sure they fit into int.
15728 (png_load, gif_load, svg_load_image):
15729 Prefer int to unsigned where either will do.
15730 (tiff_handler): New function, combining the cores of the
15731 old tiff_error_handler and tiff_warning_handler.
15732 This function is rewritten to use vsnprintf and thereby avoid
15733 stack buffer overflows. It uses only the features of vsnprintf
15734 that are common to both POSIX and native Microsoft.
15735 (tiff_error_handler, tiff_warning_handler): Use it.
15736 (tiff_load, gif_load, imagemagick_load_image):
15737 Don't assume :index value fits in 'int'.
15738 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15739 (imagemagick_load_image): Check that crop parameters fit into
15740 the integer types that MagickCropImage accepts. Don't assume
15741 Vimagemagick_render_type has a nonnegative value. Don't assume
15742 size_t fits in 'long'.
15743 (gs_load): Use printmax_t to print the widest integers possible.
15744 Check for integer overflow when computing image height and width.
15746 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15748 * xdisp.c (redisplay_window): Don't force window start if point
15749 will be invisible in the resulting window. (Bug#9324)

15753 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15754 the display spec is of the form `(space ...)'.
15755 (handle_display_spec): Return the value returned by
15756 handle_single_display_spec, not just 1 or zero.
15757 (handle_single_display_spec): If the display spec is of the form
15758 `(space ...)', and specifies display in the text area, return 2
15760 (try_cursor_movement): Check for the need to scroll more
15761 accurately, and prefer exact match for point under bidi.
15762 Don't advance `row' beyond the last row of the window.
15764 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15765 into disp_prop; all users changed.
15767 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15768 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15769 for the text covered by the display property.

15779 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15780 buffers, return left-to-right.
15781 (set_cursor_from_row): Consider candidate row a win if its glyph
15782 represents a newline and point is on that newline. Fixes cursor
15783 positioning on the newline at EOL of R2L text within L2R
15784 paragraph, and vice versa.
15785 (try_cursor_movement): Check continued rows, in addition to
15786 continuation rows. Fixes unwarranted scroll when point enters a
15787 continued line of R2L text within an L2R paragraph, or vice versa.
15788 (cursor_row_p): Consider the case of point being equal to
15789 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15790 from the end of a short line to the beginning of a continued line
15791 of R2L text within L2R paragraph.
15792 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15793 composed characters.

15808 2011-08-22 Kenichi Handa <handa@m17n.org>
15810 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15811 extra slot even if the purpose is char-code-property-table.
15813 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15815 * xdisp.c (redisplay_window): When computing centering_position,
15816 account for the height of the header line. (Bug#8874)
15818 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15819 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15820 candidate is selected by the mouse, and that candidate has a
15821 composed character under the mouse.
15823 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15824 coordinates reported by pos-visible-in-window-p for a composed
15825 character in column zero.
15827 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15829 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15831 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15833 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15834 consider it a hit if to_charpos is anywhere in the range of the
15835 composed buffer positions.
15837 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15839 * image.c (gif_load): Don't assume that each subimage has the same
15840 dimensions as the base image. Handle disposal method that is
15841 "undefined" by the gif spec (Bug#9335).
15843 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15845 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15846 (Fcondition_case): Document `debug' symbol in error handler.
15848 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15850 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15851 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15852 from an Org mode buffer to a Speedbar frame.
15854 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15855 a composition, take its buffer position from IT->cmp_it.charpos.
15856 Fixes cursor positioning at the beginning of a line that begins
15857 with a composed character.
15859 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15861 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15862 character bidirectional type, use STRONG_L instead. Fixes crashes
15863 in a buffer produced by `describe-categories'.
15865 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15866 members before the level stack, so they would be saved and
15867 restored when copying iterator state. Fixes incorrect reordering
15868 around TABs covered by display properties.
15870 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15872 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15876 * eval.c (internal_condition_case, internal_condition_case_1)
15877 (internal_condition_case_2, internal_condition_case_n):
15878 Remove unnecessary aborts (Bug#9081).
15880 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15882 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15883 has no `load' handler, try opening the file locally. (Bug#9311)
15885 2011-08-16 Ken Brown <kbrown@cornell.edu>
15887 * gmalloc.c: Expand comment.

15891 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15892 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15894 2011-08-16 Ken Brown <kbrown@cornell.edu>
15896 Fix memory allocation problems in Cygwin build (Bug#9273).
15898 * unexcw.c ( __malloc_initialized): Declare external variable.
15899 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15901 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15903 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15932 coordinates of the iterator when restoring from ppos_it.
15935 2011-08-14 Kenichi Handa <handa@m17n.org>
15937 * process.c (create_process): Call setup_process_coding_systems
15938 after the pid of the process is set to -1 (Bug#8162).
15940 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15942 * xdisp.c (move_it_in_display_line_to): Don't invoke
15943 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15944 ppos_it. Fixes vertical cursor motion when line beginning is
15945 covered by an image. (Bug#9296)
15947 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15949 * nsterm.h (ns_run_ascript): Declare.

15952 * nsfns.m (as_script, as_result, as_status): New static variables.
15953 (ns_run_ascript): New function.
15954 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15955 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15956 the event loop. Get status from as_status (Bug#7276).
15958 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15959 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15960 the event loop (Bug#7276).
15962 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15964 * gnutls.c (QCgnutls_bootprop_priority)

15985 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15986 (Fnetwork_interface_list): Allocate in increments of bytes instead
15987 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15988 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15990 (struct ifflag_def): notrailers is smart on OSX.
15991 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15992 Get hardware address with getifaddrs if available.
15994 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15996 * xdisp.c (iterate_out_of_display_property): xassert that
15997 IT->position is set to within IT->object's boundaries. Break from
15998 the loop as soon as EOB is reached; avoids infloops in redisplay
15999 when IT->position is set up wrongly due to some bug.
16000 Set IT->current to match the bidi iterator unconditionally.
16001 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16002 entry. Force push_it to save on the stack the current
16003 buffer/string position, to be restored by pop_it. Fix flags in
16004 the iterator structure wrt the object coming from a display
16005 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16006 properties. (Bug#9284)
16008 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16010 * fontset.c (fontset_get_font_group): Add proper type checks.

16023 no-display-properties-and-no-overlays under bidi display.
16024 Set disp_pos in the bidi iterator to avoid searches for display
16025 properties and overlays.
16027 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16029 * editfns.c (Fset_time_zone_rule): Document relationship with the

16033 the font entity extracted from the cache (Bug#8109).
16035 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16037 * composite.c (autocmp_chars): Don't reset point. That is done by
16038 restore_point_unwind (Bug#5984).
16040 2011-08-07 Juri Linkov <juri@jurta.org>
16042 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16043 to show the arg `TIME' instead of `TIMEVAL'.
16045 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16047 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16048 display property strides EOL and includes a newline, as in
16049 longlines-mode. (Bug#9254)
16050 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16051 word-wrap under bidirectional display. (Bug#9224)
16053 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16054 is non-zero, even if the data buffer is NULL. Fixes a crash in
16055 vertical-motion with longlines-mode. (Bug#9254)
16057 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16059 * bidi.c <bidi_cache_total_alloc>: Now static.
16060 (bidi_initialize): Initialize bidi_cache_total_alloc.
16062 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16065 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16066 amount allocated this far in `bidi_cache_total_alloc'.
16067 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16068 non-zero, only free the data buffer without restoring the cache
16069 contents. All callers changed.
16071 * dispextern.h (bidi_unshelve_cache): Update prototype.
16073 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16074 (move_it_in_display_line, move_it_to)
16075 (move_it_vertically_backward, move_it_by_lines): Replace the call
16076 to xfree to an equivalent call to bidi_unshelve_cache.
16077 (move_it_in_display_line_to): Fix logic of returning
16078 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16080 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16082 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16083 came from a string character with a `cursor' property. (Bug#9229)
16085 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16087 * Makefile.in (LIB_PTHREAD): New variable.
16088 (LIBES): Add LIB_PTHREAD (Bug#9216).
16090 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16091 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16093 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16095 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16097 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16099 * xterm.c (x_find_topmost_parent): New function.
16100 (x_set_frame_alpha): Find topmost parent window with
16101 x_find_topmost_parent and set the property there also (bug#9181).
16102 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16104 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16106 * callproc.c (Fcall_process): Avoid vfork clobbering
16107 the local vars buffer, coding_systems, current_dir.
16109 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16111 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16113 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16115 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16116 so that it is not optimized away.
16118 * xdisp.c (compute_display_string_pos): Remove unused local.
16120 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16122 Fix slow cursor motion and scrolling in large buffers with
16123 selective display, like Org Mode buffers. (Bug#9218)
16125 * dispextern.h (struct bidi_it): New member disp_prop_p.
16127 * xdisp.c: Remove one-slot cache of display string positions.
16128 (compute_display_string_pos): Accept an additional argument
16129 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16130 for a display string or property. If found, set DISP_PROP_P
16133 * bidi.c (bidi_fetch_char): Accept an additional argument
16134 DISP_PROP_P, and pass it to compute_display_string_pos.
16135 Only handle text covered by a display string if DISP_PROP_P is returned
16136 non-zero. All callers of bidi_fetch_char changed.
16138 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16140 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16142 2010-12-03 Don March <don@ohspite.net>
16144 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16145 last character M-[char] is translated to ESC [char] (bug#7541).
16147 2011-08-02 Kenichi Handa <handa@m17n.org>
16149 * lisp.h (uniprop_table): Extern it.
16151 * chartab.c (uniprop_table): Make it non-static.
16153 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16155 * xdisp.c (forward_to_next_line_start): Accept additional argument
16156 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16158 (reseat_at_next_visible_line_start): Use the bidi iterator state
16159 returned by forward_to_next_line_start to restore the state of
16160 it->bidi_it after backing up to previous newline. (Bug#9212)
16162 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16164 * regex.c (re_comp): Protoize.
16165 (re_exec): Fix return type.
16166 (regexec): Fix type of `ret'. (Bug#9203)
16168 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16170 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16171 This is needed if max-image-size is a floating-point number.
16173 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16175 * print.c (print_object): Print empty symbol as ##.
16177 * lread.c (read1): Read ## as empty symbol.
16179 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16181 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16182 setting frame foreground color (Bug#9175).
16183 (x_set_background_color): Likewise.
16185 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16186 contents (Bug#9176).
16187 (EmacsTooltip -init): Remove bezels and add shadows to
16190 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16191 or scroll bar (Bug#8470).
16193 * nsfont.m (nsfont_open): Remove assignment to voffset and
16194 unnecessary vars hshink, expand, hd, full_height, min_height.
16195 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16197 * nsterm.h (nsfont_info): Remove voffset field.
16199 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16201 Implement strike-through and overline on NextStep (Bug#8863).
16203 * nsfont.m (nsfont_open): Use underline position provided by font,
16204 instead of hard-coded value of 2.
16205 (nsfont_draw): Call ns_draw_text_decoration instead.
16207 * nsterm.h: Add declaration for ns_draw_text_decoration.
16209 * nsterm.m (ns_draw_text_decoration): New function for drawing
16210 underline, overline, and strike-through.
16211 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16212 ns_draw_text_decoration. Change treatment of cursor drawing to
16213 accommodate underlining, etc.
16215 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16217 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16220 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16222 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16223 Without this fix, if a signal arrives just after memory fills up,
16224 'malloc' might be invoked reentrantly.
16226 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16227 In other words, assume that every image size is allowed, on non-X
16228 hosts. This assumption is probably wrong, but it lets Emacs compile.
16230 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16232 * regex.c (re_iswctype): Convert return values to boolean.
16234 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16236 * xdisp.c (compute_display_string_pos): Don't use cached display
16237 string position if the buffer had its restriction changed.
16240 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16242 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16244 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16246 Integer signedness and overflow and related fixes. (Bug#9079)
16248 * bidi.c: Integer size and overflow fixes.
16249 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16250 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16251 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16252 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16253 (bidi_find_other_level_edge):
16254 Use ptrdiff_t instead of EMACS_INT where either will do.
16255 This works better on 32-bit hosts configured --with-wide-int.
16256 (bidi_cache_ensure_space): Check for size-calculation overflow.
16257 Use % rather than repeated addition, for better worst-case speed.
16258 Don't set bidi_cache_size until after xrealloc returns, because it
16260 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16261 (bidi_cache_ensure_space): Also check that the bidi cache size
16262 does not exceed that of the largest Lisp string or buffer. See Eli
16263 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16265 * alloc.c (__malloc_size_t): Remove.
16266 All uses replaced by size_t. See Andreas Schwab's note
16267 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16269 * image.c: Improve checking for integer overflow.
16270 (check_image_size): Assume that f is nonnull, since
16271 it is always nonnull in practice. This is one less thing to
16272 worry about when checking for integer overflow later.
16273 (x_check_image_size): New function, which checks for integer
16274 overflow issues inside X.
16275 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16276 This removes the need for a memory_full check.
16277 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16278 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16279 (xbm_read_bitmap_data): Change locals back to 'int', since
16280 their values must fit in 'int'.
16281 (xpm_load_image, png_load, tiff_load):
16282 Invoke x_create_x_image_and_pixmap earlier,
16283 to avoid much needless work if the image is too large.
16284 (tiff_load): Treat overly large images as if
16285 x_create_x_image_and_pixmap failed, not as malloc failures.
16286 (gs_load): Use x_check_image_size.
16288 * gtkutil.c: Omit integer casts.
16289 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16290 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16292 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16294 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16295 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16296 would wrongly return t on a 64-bit host.
16298 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16299 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16300 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16301 and therefore cause GCC to emit a bogus diagnostic in some cases.
16303 * image.c: Integer signedness and overflow and related fixes.
16304 This is not an exhaustive set of fixes, but it's time to
16305 record what I've got.
16306 (lookup_pixel_color, check_image_size): Remove redundant decls.
16307 (check_image_size): Don't assume that arbitrary EMACS_INT values
16308 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16309 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16310 (tiff_load, imagemagick_load_image):
16311 Check for overflow in size calculations.
16312 (x_create_x_image_and_pixmap): Remove unnecessary test for
16313 xmalloc returning NULL; that can't happen.
16314 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16315 (xpm_color_bucket): Use better integer hashing function.
16316 (xpm_cache_color): Don't possibly over-allocate memory.
16317 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16318 (gif_memory_source):
16319 Use ptrdiff_t, not int or size_t, to record sizes.
16320 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16321 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16322 either works, as we prefer signed integers.
16323 (tiff_read_from_memory, tiff_write_from_memory):
16324 Return tsize_t, not size_t, since that's what the TIFF API wants.
16325 (tiff_read_from_memory): Don't fail simply because the read would
16326 go past EOF; instead, return a short read.
16327 (tiff_load): Omit no-longer-needed casts.
16328 (Fimagemagick_types): Don't assume size fits into 'int'.
16330 Improve hashing quality when configured --with-wide-int.
16331 * fns.c (hash_string): New function, taken from sxhash_string.
16332 Do not discard information about ASCII character case; this
16333 discarding is no longer needed.
16334 (sxhash-string): Use it. Change sig to match it. Caller changed.
16335 * lisp.h: Declare it.
16336 * lread.c (hash_string): Remove, since we now use fns.c's version.
16337 The fns.c version returns a wider integer if --with-wide-int is
16338 specified, so this should help the quality of the hashing a bit.
16340 * emacs.c: Integer overflow minor fix.
16341 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16342 Define only if GNU_LINUX.
16343 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16345 * dispnew.c: Integer signedness and overflow fixes.
16346 Remove unnecessary forward decls, that were a maintenance hassle.
16347 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16349 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16350 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16351 (prepare_desired_row, line_draw_cost):
16352 Use int, not unsigned, where either works.
16353 (save_current_matrix, restore_current_matrix):
16354 Use ptrdiff_t, not size_t, where either works.
16355 (init_display): Check for overflow more accurately, and without
16356 relying on undefined behavior.
16358 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16359 Remove, replacing with the new symbols in lisp.h. All uses changed.
16360 * fileio.c (make_temp_name):
16361 * filelock.c (lock_file_1, lock_file):
16362 * xdisp.c (message_dolog):
16363 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16364 Use pMd etc. instead.
16365 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16366 replacing the pWIDE etc. symbols removed from editfns.c.
16368 * keyboard.h (num_input_events): Now uintmax_t.
16369 This is (very slightly) less likely to mess up due to wraparound.
16372 * buffer.c: Integer signedness fixes.
16373 (alloc_buffer_text, enlarge_buffer_text):
16374 Use ptrdiff_t rather than size_t when either will do, as we prefer
16377 * alloc.c: Integer signedness and overflow fixes.
16378 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16379 (__malloc_size_t): Default to size_t, not to int.
16380 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16381 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16382 Prefer ptrdiff_t to size_t when either would do, as we prefer
16384 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16385 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16386 Now const. Initialize with values that are in range even if char
16388 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16389 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16390 These functions do the right thing with sizes > 2**32.
16391 (check_depth): Now ptrdiff_t, not int.
16392 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16393 Adjust to new way of storing sizes. Check for size overflow bugs
16395 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16396 slightly wrong anyway, as it missed one instance of
16397 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16398 (refill_memory_reserve): Omit needless cast to size_t.
16399 (mark_object_loop_halt): Mark as externally visible.
16401 * xselect.c: Integer signedness and overflow fixes.
16402 (Fx_register_dnd_atom, x_handle_dnd_message):
16403 Use ptrdiff_t, not size_t, since we prefer signed.
16404 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16405 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16406 x_dnd_atoms_size and x_dnd_atoms_length.
16408 * doprnt.c: Prefer signed to unsigned when either works.
16410 * doprnt.c (doprnt):
16412 * xdisp.c (vmessage):
16413 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16414 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16415 prefer signed arithmetic to avoid comparison confusion.
16416 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16417 but is a bit tricky.
16419 Assume freestanding C89 headers, string.h, stdlib.h.
16420 * data.c, doprnt.c, floatfns.c, print.c:
16421 Include float.h unconditionally.
16422 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16423 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16424 * regex.c: Likewise for stddef.h, string.h.
16425 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16426 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16427 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16428 (STDC_HEADERS): Remove obsolete defines.
16429 * sysdep.c: Include limits.h unconditionally.
16431 Assume support for memcmp, memcpy, memmove, memset.
16432 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16433 * regex.c (memcmp, memcpy):
16434 Remove; we assume C89 now.
16436 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16437 (__malloc_safe_bcopy): Remove; no longer needed.
16439 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16440 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16441 well either way, and we prefer signed to unsigned.
16443 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16445 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16446 closes the connection while we're reading (bug#9182).
16448 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16450 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16451 are specified (Bug#9168).
16453 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16455 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16456 Found by GCC static checking and --with-wide-int on a 32-bit host.
16458 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16460 * xdisp.c (compute_display_string_pos): Fix logic of caching
16461 previous display string position. Initialize cached_prev_pos to
16462 -1. Fixes slow-down at the beginning of a buffer.
16464 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16466 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16467 for attrs[LFACE_FONTSET_INDEX].
16469 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16471 * xml.c (parse_region): Remove unused local
16472 that was recently introduced.
16474 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16476 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16477 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16479 * xdisp.c (move_it_in_display_line_to): Record the best matching
16480 position for TO_CHARPOS while scanning the line, and restore it on
16481 exit if none of the characters scanned was an exact match.
16482 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16483 when exact match is impossible due to invisible text, and the
16484 lines are truncated.
16486 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16488 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16491 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16493 Fix a significant slow-down of cursor motion with C-n, C-p,
16494 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16495 auto-repeat under bidi redisplay in fontified buffers.
16496 * xdisp.c (compute_stop_pos_backwards): New function.
16497 (next_element_from_buffer): Call compute_stop_pos_backwards to
16498 find a suitable prev_stop when we find ourselves before
16500 (reseat): Don't look for prev_stop, as that could mean a very long
16502 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16503 <cached_disp_overlay_modiff>: Cache for last found display string
16505 (compute_display_string_pos): Return the cached position if asked
16506 about the same buffer in the same area of character positions, and
16507 the buffer wasn't changed since the time the display string
16508 position was cached.
16510 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16512 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16513 is an integer, which is important for empty lines. (Bug#9149)
16515 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16517 * frame.c (Fmodify_frame_parameters): In tty case, update the
16518 default face if necessary (Bug#4238).
16520 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16522 * editfns.c (Fstring_to_char): No need to explain what a character
16523 is in the docstring (Bug#6576).
16525 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16527 * xml.c (parse_region): Make sure we always return a tree.
16529 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16531 * xml.c (parse_region): If a document contains only comments,
16534 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16536 * xml.c (make_dom): Return comments, too.
16538 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16541 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16542 and the surrounding thread.
16543 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16544 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16545 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16547 * s/openbsd.h (BROKEN_SIGIO): Define.
16548 * unexelf.c (unexec) [__OpenBSD__]:
16549 Don't update the .mdebug section of the Alpha COFF symbol table.
16551 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16553 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16556 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16558 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16559 This fixes some race conditions on the permissions of any newly
16562 * alloc.c (valid_pointer_p): Use pipe, not open.
16563 This fixes some permissions issues when debugging.
16565 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16566 If fchown fails to set both uid and gid, try to set just gid,
16567 as that is sometimes allowed. Adjust the file's mode to eliminate
16568 setuid or setgid bits that are inappropriate if fchown fails.
16570 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16572 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16578 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16580 * lread.c (read_integer): Unread even EOF character.
16581 (read1): Likewise. Properly record start position of symbol.
16583 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16584 symbol character follows.
16586 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16588 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16589 This works around a problem with the previous change to Fcopy_file.
16590 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16591 and without this change, GCC might complain about discarding
16592 fchown's return value.
16594 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16596 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16598 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16600 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16602 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16604 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16605 it's used from the C level.
16607 * process.c: Use the same condition for POLL_FOR_INPUT in both
16608 keyboard.c and process.c (bug#1858).
16610 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16612 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16613 (Fgnutls_boot): Use it.
16615 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16617 * doc.c (Fsubstitute_command_keys): Revert last change.
16619 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16621 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16622 quotes the next character, and doesn't affect other longer
16623 sequences (bug#8935).
16625 * lread.c (syms_of_lread): Clarify that is isn't only
16626 `eval-buffer' and `eval-defun' that's affected by
16627 `lexical-binding' (bug#8460).
16629 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16631 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16632 bidi redisplay when a line includes both an image and is truncated.
16634 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16636 Fix minor problems found by static checking.
16637 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16638 (elsz): Now a signed constant, not a size_t var. We prefer signed
16639 types to unsigned, to avoid integer comparison confusion. Without
16640 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16641 "cannot optimize loop, the loop counter may overflow", a symptom
16643 * indent.c (Fvertical_motion): Mark locals as initialized.
16644 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16646 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16648 * search.c (Fre_search_backward): Mention `case-fold-search' in
16649 all the re_search_* functions (bug#8138).

16669 buffer position was specified. Initialize paragraph_embedding to
16671 (reseat_to_string): Initialize the bidi iterator.
16672 (display_string): If we need to ignore text properties of
16673 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16674 original value of -1 will not work with bidi.)
16675 (compute_display_string_pos): First arg is now struct
16676 `text_pos *'; all callers changed. Support display properties on
16678 (compute_display_string_end): Support display properties on Lisp
16680 (init_iterator, reseat_1, reseat_to_string): Initialize the
16681 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16682 when iterating on a string not from display properties).
16683 (compute_display_string_pos, compute_display_string_end):
16684 Fix calculation of the object to scan. Fixes an error when using
16686 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16687 base_level_stop; instead, set base_level_stop to BEGV.
16688 Fixes crashes in vertical-motion.
16689 (next_element_from_buffer): Improve commentary for when
16690 the iterator is before prev_stop.
16691 (init_iterator): Initialize bidi_p from the default value of
16692 bidi-display-reordering, not from buffer-local value. Use the
16693 buffer-local value only if initializing for buffer iteration.
16694 (handle_invisible_prop): Support invisible properties on strings
16695 that are being bidi-reordered.

16702 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16703 (init_iterator): Don't initialize it->bidi_p for strings
16705 (reseat_to_string): Initialize it->bidi_p for strings here.

16713 (get_visually_first_element): New function, refactored from common
16714 parts of next_element_from_buffer, next_element_from_string, and
16715 next_element_from_c_string.
16716 (tool_bar_lines_needed, redisplay_tool_bar)
16717 (display_menu_bar): Force left-to-right direction. Add a FIXME
16718 comment for making that be controlled by a user option.
16719 (push_it, pop_it): Save and restore the state of the
16720 bidi iterator. Save and restore the bidi_p flag.

16727 (get_overlay_strings_1, push_display_prop): Set up the bidi
16728 iterator for displaying display or overlay strings.
16729 (forward_to_next_line_start): Don't use the shortcut if
16731 (back_to_previous_visible_line_start): If handle_display_prop
16732 pushed the iterator stack, restore the internal state of the bidi
16733 iterator by calling bidi_pop_it same number of times.
16734 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16735 and we are bidi-iterating, don't decrement the iterator position;
16736 instead, set the first_elt flag in the bidi iterator, to produce
16738 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16739 (push_display_prop): xassert that we are iterating a buffer.
16740 (push_it, pop_it): Save and restore paragraph_embedding member.
16741 (handle_single_display_spec, next_overlay_string)
16742 (get_overlay_strings_1, reseat_1, reseat_to_string)
16743 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16744 correctly. Don't assume unibyte strings are not bidi-reordered.

16751 (pop_it): Call iterate_out_of_display_property only if we are
16752 popping after iteration over a string that came from a display
16753 property. Fix a typo in popping stretch info. Add an assertion
16754 for verifying that the iterator position is in sync with the bidi
16756 (handle_single_display_spec, get_overlay_strings_1)
16757 (push_display_prop): Fix initialization of paragraph direction for
16758 string when that of the parent object is not yet determined.

16770 (try_scrolling, redisplay_window, display_line): Use them when
16771 saving a temporary copy of the iterator and restoring it back.
16772 (back_to_previous_visible_line_start, reseat_1)
16773 (init_iterator): Empty the bidi cache "stack".
16774 (move_it_in_display_line_to): If iterator ended up at
16775 EOL, but we never saw any buffer positions smaller than
16776 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16777 motion in bidi-reordered lines.

16781 displayed in margins. (Bug#8133) (Bug#8867)
16782 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16784 (pos_visible_p): Support positions in bidi-reordered lines.
16785 Save and restore bidi cache.
16787 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16788 (bidi_paragraph_info): Delete unused struct.

16806 Support iteration over a string.
16807 (bidi_set_sor_type, bidi_resolve_explicit_1)
16808 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16809 can now be zero (for strings); special values 0 and -1 were
16810 changed to -1 and -2, respectively.
16811 (bidi_char_at_pos): New function.
16812 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16823 (bidi_initialize): Initialize the bidi cache start stack pointer.
16824 (bidi_cache_ensure_space): New function, refactored from part of

16840 * dispextern.h (struct bidi_string_data): New structure.
16841 (struct bidi_it): New member `string'. Make flag members be 1-bit

16845 (bidi_push_it, bidi_pop_it): Add prototypes.
16846 (struct iterator_stack_entry): New members bidi_p,
16847 paragraph_embedding, and from_disp_prop_p.
16848 (struct it): Member bidi_p is now a bit field 1 bit wide.
16849 (bidi_shelve_cache, bidi_unshelve_cache):
16850 Declare prototypes.
16852 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

16895 Pass Qx_lost_selection_functions rather than
16896 Vx_lost_selection_functions to Frun_hook_with_args.
16898 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16900 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16901 The old code sometimes used this field without initializing it.
16903 * alloc.c (gc_sweep): Don't read past end of array.
16904 In theory, the old code could also have corrupted Emacs internals,

17210 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17211 subseconds part to the entropy, as that's a bit more random.
17212 Prefer signed to unsigned, since the signedness doesn't matter and
17213 in general we prefer signed. When given a limit, use a
17214 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17215 latter isn't right if USE_2_TAGS_FOR_INTS.
17216 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17217 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17230 This is more efficient than Ffile_directory_p and avoids a minor race.

17234 * buffer.c (Foverlay_put): Say what the return value is

17260 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

17360 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
17362 * eval.c (struct backtrace): Simplify and port the data structure.
17363 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17364 signed bit field, as this assumption is not portable and it makes
17365 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17366 "char debug_on_exit : 1" as this is not portable either; instead,
17367 use the portable "unsigned int debug_on_exit : 1". Remove unused
17368 member evalargs. Remove obsolete comments about cc bombing out.
17370 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17438 (emacs_fixed_new): Set priv->f to argument.
17439 (emacs_fixed_get_preferred_width)
17440 (emacs_fixed_get_preferred_height): Use min_width/height from
17441 frames size_hint to set minimum and natural (Bug#8919).
17442 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17443 and use min_width/height from frames size_hint to set
17444 min_width/height (Bug#8919).
17446 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

17464 Use gnulib's dup2 module instead of rolling our own.
17465 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17467 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17469 * dispnew.c (scrolling_window): Before scrolling, turn off a

17532 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17534 Integer and buffer overflow fixes (Bug#8873).
17536 * print.c (printchar, strout): Check for string overflow.
17537 (PRINTPREPARE, printchar, strout):
17538 Don't set size unless allocation succeeds.
17540 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17541 for sizes. Check for string overflow more accurately.
17542 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17544 * macros.c: Integer and buffer overflow fixes.
17545 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17546 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17547 Use ptrdiff_t, not int, for sizes.

17550 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17552 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17554 * lread.c: Integer overflow fixes.
17555 (read_integer): Radix is now EMACS_INT, not int,
17556 to improve quality of diagnostics for out-of-range radices.
17557 Calculate buffer size correctly for out-of-range radices.
17558 (read1): Check for integer overflow in radices, and in
17559 read-circle numbers.
17560 (read_escape): Avoid int overflow.
17561 (Fload, openp, read_buffer_size, read1)
17562 (substitute_object_recurse, read_vector, read_list, map_obarray):
17563 Use ptrdiff_t, not int, for sizes.

17578 2011-06-22 Leo Liu <sdl.web@gmail.com>
17580 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17581 Move to minibuffer.el.
17583 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17585 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17586 The following patches are for when GLYPH_DEBUG && !XASSERT.
17587 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17588 * dispnew.c (flush_stdout):
17589 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17590 Mark as externally visible.
17591 * dispnew.c (check_window_matrix_pointers): Now static.
17592 * dispnew.c (window_to_frame_vpos):
17593 * xfns.c (unwind_create_frame):
17594 * xterm.c (x_check_font): Remove unused local.
17595 * scroll.c (CHECK_BOUNDS):
17596 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17597 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17598 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17599 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17600 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17602 (debug_method_add): Use va_list and vsprintf rather than relying
17603 on undefined behavior with wrong number of arguments.
17604 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17605 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17606 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17607 since we're not interested in debugging glyphs with old libraries.
17608 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17609 GCC 4.6.0's static checking.
17611 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17613 Integer overflow and signedness fixes (Bug#8873).

17623 (x_create_bitmap_from_xpm_data):
17624 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17625 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17627 * xfaces.c (load_pixmap):
17628 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17629 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17630 (.bitmaps_last, struct x_output.icon_bitmap):
17631 Use ptrdiff_t, not int, for bitmap indexes.
17632 (x_allocate_bitmap_record): Check for size overflow.
17633 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17635 Use ptrdiff_t, not int, for overlay counts.
17636 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17637 * editfns.c (overlays_around, get_pos_property):
17638 * textprop.c (get_char_property_and_overlay):
17639 * xdisp.c (next_overlay_change, note_mouse_highlight):
17640 * xfaces.c (face_at_buffer_position):
17641 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17642 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17643 (Fnext_overlay_change, Fprevious_overlay_change)
17644 (mouse_face_overlay_overlaps, Foverlays_in):
17645 Use ptrdiff_t, not int, for sizes.
17646 (overlays_at, overlays_in): Check for size-calculation overflow.
17648 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17650 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17651 (x_session_initialize): Do not assume string length fits in int.
17653 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17654 This is unlikely, but can occur if DPI is outlandish.
17656 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17657 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17659 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17660 * xrdb.c (magic_file_p, search_magic_path):
17661 Omit last arg SUFFIX; it was always 0. All callers changed.
17662 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17664 * xfont.c (xfont_match): Avoid need for strlen.
17666 * xfns.c: Don't assume strlen fits in int.
17667 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17669 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17670 not unsigned long, as we prefer signed integers. All callers changed.
17671 Detect integer overflow in repeat count.
17672 (message_dolog): Don't assume print length fits in 39 bytes.
17673 (display_mode_element): Don't assume strlen fits in int.
17675 * termcap.c: Don't assume sizes fit in int and never overflow.
17676 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17677 (gobble_line): Check for size-calculation overflow.
17679 * minibuf.c (Fread_buffer):
17680 * lread.c (intern, intern_c_string):
17681 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17682 Don't assume string length fits in int.
17684 * keyboard.c (parse_tool_bar_item):
17685 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17687 * font.c: Don't assume string length fits in int.
17688 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):

17691 Don't assume integer property fits in fixnum.
17692 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17694 * filelock.c: Fix some buffer overrun and integer overflow issues.
17695 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17696 Reformulate so as not to need the command string.
17697 Invoke gzip -cd rather than gunzip, as it's more portable.
17698 (lock_info_type, lock_file_1, lock_file):
17699 Don't assume pid_t and time_t fit in unsigned long.
17700 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17701 (current_lock_owner): Prefer signed type for sizes.
17702 Use memcpy, not strncpy, where memcpy is what is really wanted.
17703 Don't assume (via atoi) that time_t and pid_t fit in int.
17704 Check for time_t and/or pid_t out of range, e.g., via a network share.
17705 Don't alloca where an auto var works fine.
17707 * fileio.c: Fix some integer overflow issues.
17708 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17709 Don't assume string length fits in int.
17710 (directory_file_name): Don't assume string length fits in long.
17711 (make_temp_name): Don't assume pid fits in int, or that its print
17712 length is less than 20.
17714 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17716 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17718 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17720 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17721 We prefer signed integers, even for size calculations.
17723 * emacs.c: Don't assume string length fits in 'int'.
17724 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17725 (main): Don't invoke strlen when not needed.

17730 * callproc.c (getenv_internal_1, getenv_internal)
17731 (Fgetenv_internal):
17732 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17734 * lread.c (invalid_syntax): Omit length argument.
17735 All uses changed. This doesn't fix a bug, but it simplifies the
17736 code away from its former Hollerith-constant appearance, and it's
17737 one less 'int' to worry about when looking at integer-overflow issues.
17738 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17740 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17741 This didn't break anything, but it didn't help either.
17742 It's confusing to put a bogus integer in a place where the actual
17743 value does not matter.
17744 (LIST_END_P): Remove unused macro and its bogus comment.
17745 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17747 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17748 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17750 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17751 We prefer signed types, and the value cannot exceed the EMACS_INT
17752 range anyway (because otherwise the length would not be representable).
17753 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17754 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17755 This avoids a GCC warning when WIDE_EMACS_INT.
17757 * indent.c (sane_tab_width): New function.
17758 (current_column, scan_for_column, Findent_to, position_indentation)
17759 (compute_motion): Use it. This is just for clarity.
17760 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17762 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17764 * lisp.h (lint_assume): New macro.
17765 * composite.c (composition_gstring_put_cache):
17766 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17768 * editfns.c, insdel.c:
17769 Omit unnecessary forward decls, to simplify future changes.
17771 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17773 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17775 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17776 Use much-faster test for byte-length change.
17777 Don't assume string byte-length fits in 'int'.
17778 Check that character arg fits in 'int'.
17779 (mapcar1): Declare byte as byte, for clarity.
17781 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17783 * fns.c (concat): Catch string overflow earlier.
17784 Do not rely on integer wraparound.
17786 * dispextern.h (struct it.overlay_strings_charpos)
17787 (struct it.selective): Now EMACS_INT, not int.
17788 * xdisp.c (forward_to_next_line_start)
17789 (back_to_previous_visible_line_start)
17790 (reseat_at_next_visible_line_start, next_element_from_buffer):
17791 Don't arbitrarily truncate the value of 'selective' to int.
17793 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17795 * composite.c: Don't truncate sizes to 'int'.
17796 (composition_gstring_p, composition_reseat_it)
17797 (composition_adjust_point): Use EMACS_INT, not int.
17798 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17799 not EMACS_UINT, for indexes.
17801 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17803 * buffer.c: Include <verify.h>.
17804 (struct sortvec.priority, struct sortstr.priority):
17805 Now EMACS_INT, not int.
17806 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17807 (struct sortstr.size, record_overlay_string)
17808 (struct sortstrlist.size, struct sortlist.used):
17809 Don't truncate size to int.
17810 (record_overlay_string): Check for size-calculation overflow.
17811 (init_buffer_once): Check at compile-time, not run-time.
17813 2011-06-22 Jim Meyering <meyering@redhat.com>
17815 Don't leak an XBM-image-sized buffer
17816 * image.c (xbm_load): Free the image buffer after using it.
17818 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17821 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17822 that Sun C diagnosed.
17823 * fns.c (secure_hash): Fix pointer signedness issue.
17824 * intervals.c (static_offset_intervals): New function.
17825 (offset_intervals): Use it.
17827 2011-06-21 Leo Liu <sdl.web@gmail.com>
17830 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17833 * fns.c (secure_hash): Rename from crypto_hash_function and change
17834 the first arg to accept symbols.
17835 (Fsecure_hash): New primitive.
17836 (syms_of_fns): New symbols.
17838 2011-06-20 Deniz Dogan <deniz@dogan.se>
17840 * process.c (Fset_process_buffer): Clarify return value in
17843 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17845 * dispnew.c (add_window_display_history): Use BVAR.
17847 * xdisp.c (debug_method_add): Use BVAR.
17848 (check_window_end, dump_glyph_matrix, dump_glyph)
17849 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17851 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17854 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17855 check till after the cache is created in init_frame_faces.
17857 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17859 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17861 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17863 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17864 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17865 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17867 Improve buffer-overflow checking (Bug#8873).
17868 * fileio.c (Finsert_file_contents):
17869 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17870 Remove the old (too-loose) buffer overflow checks.
17871 They weren't needed, since make_gap checks for buffer overflow.
17872 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17873 The old code merely checked for Emacs fixnum overflow, and relied
17874 on undefined (wraparound) behavior. The new code avoids undefined
17875 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17877 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17878 Tune. Don't use wider integers than needed. Don't use alloca.
17879 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17881 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17883 * insdel.c, lisp.h (buffer_overflow): New function.
17884 (insert_from_buffer_1, replace_range, replace_range_2):
17885 * insdel.c (make_gap_larger):
17886 * editfns.c (Finsert_char):
17887 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17889 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17891 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17893 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17895 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17896 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17898 * fileio.c: Don't assume EMACS_INT fits in off_t.
17899 (emacs_lseek): New static function.
17900 (Finsert_file_contents, Fwrite_region): Use it.
17901 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17903 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17905 * fns.c: Don't overflow int when computing a list length.
17906 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17907 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17908 truncation on 64-bit hosts. Check for QUIT every
17909 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17910 faster and is responsive enough.
17911 (Flength): Report an error instead of overflowing an integer.
17912 (Fsafe_length): Return a float if the value is not representable
17913 as a fixnum. This shouldn't happen except in contrived situations.
17914 (Fnthcdr, Fsort): Don't assume list length fits in int.
17915 (Fcopy_sequence): Don't assume vector length fits in int.
17917 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17918 (header_size, word_size): New constants.
17919 (allocate_vectorlike): Don't check size overflow here.
17920 (allocate_vector): Check it here instead, since this is the only
17921 caller of allocate_vectorlike that could cause overflow.
17922 Check that the new vector's length is representable as a fixnum.
17924 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17925 The previous code was bogus. For example, next_almost_prime (32)
17926 returned 39, which is undesirable as it is a multiple of 3; and
17927 next_almost_prime (24) returned 25, which is a multiple of 5 so
17928 why was the code bothering to check for multiples of 7?
17930 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17932 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17934 Variadic C functions now count arguments with ptrdiff_t.
17935 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17936 Back then I didn't know that the Emacs coding style prefers signed int.
17937 Also, in the meantime I found a few more instances where arguments
17938 were being counted with int, which may truncate counts on 64-bit
17939 machines, or EMACS_INT, which may be unnecessarily wide.
17940 * lisp.h (struct Lisp_Subr.function.aMANY)
17941 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17942 Arg counts are now ptrdiff_t, not size_t.
17943 All variadic functions and their callers changed accordingly.
17944 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17945 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17946 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17947 * callint.c (Fcall_interactively): Check arg count for overflow,
17948 to avoid potential buffer overrun. Use signed char, not 'int',
17949 for 'varies' array, so that we needn't bother to check its size
17950 calculation for overflow.
17951 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17952 * eval.c (apply_lambda):
17953 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17954 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17955 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17957 * callint.c (Fcall_interactively): Don't use index var as event count.
17959 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17960 * mem-limits.h (SIZE): Remove; no longer used.
17962 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17964 Remove unnecessary casts.
17965 * xterm.c (x_term_init):
17966 * xfns.c (x_set_border_pixel):
17967 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17968 These aren't needed now that we assume ANSI C.
17970 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17971 It's more likely to cause problems (due to unsigned overflow)
17974 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17976 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17978 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17980 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17982 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17984 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17986 GLYPH_CODE_FACE returns EMACS_INT, not int.
17987 * dispextern.h (merge_faces):
17988 * xfaces.c (merge_faces):
17989 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17990 Don't assume EMACS_INT fits in int.
17992 * character.h (CHAR_VALID_P): Remove unused parameter.
17993 * fontset.c, lisp.h, xdisp.c: All uses changed.
17995 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17997 * fns.c (concat): Minor tuning based on overflow analysis.
17998 This doesn't fix any bugs. Use int to hold character, instead
17999 of constantly refetching from Emacs object. Use XFASTINT, not
18000 XINT, for value known to be a character. Don't bother comparing
18001 a single byte to 0400, as it's always less.
18003 * floatfns.c (Fexpt):
18004 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18006 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18009 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18011 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18012 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18013 incorrectly succeed when S was a string, because 4294967386 was
18014 truncated before it was used.
18016 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18017 Otherwise, an out-of-range integer could cause undefined behavior
18020 * composite.c: Use int, not EMACS_INT, for characters.
18021 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18022 EMACS_INT, for values that are known to be in character range.
18023 This doesn't fix any bugs but is the usual style inside Emacs and
18024 may generate better code on 32-bit machines.
18026 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18027 This is for reasons similar to the recent CHAR_STRING fix.
18028 * charset.c (Fencode_char): Check that character arg is actually
18029 a character. Pass an int to ENCODE_CHAR.
18030 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18031 wider than 'int', as a compile-time check to prevent future regressions
18034 * character.c (char_string): Remove unnecessary casts.
18036 Make sure a 64-bit char is never passed to CHAR_STRING.
18037 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18038 by silently ignoring the top 32 bits, allowing some values
18039 that were far too large to be valid characters.
18040 * character.h: Include <verify.h>.
18041 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18042 arguments are no wider than unsigned, as a compile-time check
18043 to prevent future regressions in this area.
18045 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18046 (Fsubst_char_in_region):
18048 * xdisp.c (decode_mode_spec_coding):
18049 Adjust to CHAR_STRING's new requirement.
18050 * editfns.c (Finsert_char, Fsubst_char_in_region):
18051 * fns.c (concat): Check that character args are actually
18052 characters. Without this test, these functions did the wrong
18053 thing with wildly out-of-range values on 64-bit hosts.
18055 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18056 These casts should not be needed on 32-bit hosts, either.
18057 * keyboard.c (read_char):
18058 * lread.c (Fload): Remove casts to unsigned.
18060 * lisp.h (UNSIGNED_CMP): New macro.
18061 This fixes comparison bugs on 64-bit hosts.
18062 (ASCII_CHAR_P): Use it.
18063 * casefiddle.c (casify_object):
18064 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18065 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18066 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18067 * dispextern.h (FACE_FROM_ID):
18068 * keyboard.c (read_char): Use UNSIGNED_CMP.
18070 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18071 not to EMACS_INT, to avoid GCC warning.
18073 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18075 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18076 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18077 isn't needed on 32-bit machines.
18079 * buffer.c (Fgenerate_new_buffer_name):
18080 Use EMACS_INT for count, not int.
18081 (advance_to_char_boundary): Return EMACS_INT, not int.
18083 * data.c (Qcompiled_function): Now static.
18085 * window.c (window_body_lines): Now static.
18087 * image.c (gif_load): Rename local to avoid shadowing.
18089 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18090 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18091 * alloc.c (make_save_value): Integer argument is now of type
18092 ptrdiff_t, not int.
18093 (mark_object): Use ptrdiff_t, not int.
18094 * lisp.h (pD): New macro.
18095 * print.c (print_object): Use it.
18097 * alloc.c: Use EMACS_INT, not int, to count objects.
18098 (total_conses, total_markers, total_symbols, total_vector_size)
18099 (total_free_conses, total_free_markers, total_free_symbols)
18100 (total_free_floats, total_floats, total_free_intervals)
18101 (total_intervals, total_strings, total_free_strings):
18102 Now EMACS_INT, not int. All uses changed.
18103 (Fgarbage_collect): Compute overall total using a double, so that
18104 integer overflow is less likely to be a problem. Check for overflow
18105 when converting back to an integer.
18106 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18107 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18108 These were 'int' variables that could overflow on 64-bit hosts;
18109 they were never used, so remove them instead of repairing them.
18110 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18111 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18112 Previously, this ceilinged at INT_MAX, but that doesn't work on
18114 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18116 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18117 (allocate_vectorlike): Check for ptrdiff_t overflow.
18118 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18119 when a (possibly-narrower) signed value would do just as well.
18120 We prefer using signed arithmetic, to avoid comparison confusion.
18122 * alloc.c: Catch some string size overflows that we were missing.
18123 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18124 for convenience in STRING_BYTES_MAX.
18125 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18126 The definition here is exact; the one in lisp.h was approximate.
18127 (allocate_string_data): Check for string overflow. This catches
18128 some instances we weren't catching before. Also, it catches
18129 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18130 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18131 and ptrdiff_t and EMACS_INT are both 64 bits.
18133 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18134 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18135 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18137 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18139 * alloc.c (Fmake_string): Check for out-of-range init.
18141 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18143 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18145 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18147 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18148 xg_get_default_scrollbar_width.
18150 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18151 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18152 (style_changed_cb): Call update_theme_scrollbar_width and call
18153 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18154 all frames (Bug#8505).
18155 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18156 Call gtk_window_set_resizable if HAVE_GTK3.
18157 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18158 and height if HAVE_GTK3 (Bug#8505).
18159 (scroll_bar_width_for_theme): New variable.
18160 (update_theme_scrollbar_width): New function.
18161 (xg_get_default_scrollbar_width): Move code to
18162 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18163 (xg_initialize): Call update_theme_scrollbar_width.
18165 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18167 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18169 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18171 * frame.c (make_frame): Call other_buffer_safely instead of
18174 * window.c (temp_output_buffer_show): Call display_buffer with
18175 second argument Vtemp_buffer_show_specifiers and reset latter
18176 immediately after the call.
18177 (Vtemp_buffer_show_specifiers): New variable.
18178 (auto_window_vscroll_p, next_screen_context_lines)
18179 (Vscroll_preserve_screen_position): Remove leading asterisks from
18182 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18184 Fix minor problems found by GCC 4.6.0 static checking.
18185 * buffer.c (Qclone_number): Remove for now, as it's unused.
18186 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18187 (record_buffer): Remove unused local.
18188 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18189 (set_frame_buffer_list): Remove; unused.
18190 * frame.h (other_visible_frames): Remove decl.
18191 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18192 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18193 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18195 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18196 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18197 Define only if HAVE_GPM.
18198 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18199 (update_hints_inhibit): Remove; never set. All uses removed.
18200 * widgetprv.h (emacsFrameClassRec): Remove decl.
18201 * window.c (delete_deletable_window): Now returns void, since it
18202 wasn't returning anything.
18203 (compare_window_configurations): Remove unused locals.
18204 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18205 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18206 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18207 the same widths as pointers. This follows up on the 2011-05-06 patch.
18208 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18209 * xterm.h: Likewise.
18210 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18212 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18214 * makefile.w32-in: Update dependencies.
18215 (LISP_H): Add lib/intprops.h.
18217 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18219 * image.c (gif_load): Add animation frame delay to the metadata.
18220 (syms_of_image): Use DEFSYM. New symbol `delay'.
18222 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18224 * window.c (delete_deletable_window): Re-add.

18678 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18680 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18682 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18684 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18686 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18687 in the current matrix if keep_current_p is non-zero.
18689 2011-06-04 Eli Zaretskii <eliz@gnu.org>
18691 * bidi.c (bidi_level_of_next_char): Fix last change.
18693 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18695 Support bidi reordering of text covered by display properties.
18697 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18698 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18699 (bidi_cache_search, bidi_cache_iterator_state)
18700 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18701 (bidi_level_of_next_char, bidi_move_to_visually_next):
18702 Support character positions inside a run of characters covered by a
18704 (bidi_paragraph_init, bidi_resolve_explicit_1)
18705 (bidi_level_of_next_char): Call bidi_fetch_char and
18706 bidi_fetch_char_advance instead of FETCH_CHAR and
18707 FETCH_CHAR_ADVANCE.
18708 (bidi_init_it): Initialize new members.
18709 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18711 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18712 instead of using explicit *_CHAR codes.
18713 (bidi_resolve_explicit, bidi_resolve_weak):
18714 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18715 bidirectional text is supported only in multibyte buffers.
18716 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18717 it to initialize the frame_window_p member of struct bidi_it.
18718 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18719 (bidi_resolve_explicit, bidi_resolve_weak)
18720 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
18721 bidi_it->nchars is non-positive.
18722 (bidi_level_of_next_char): Don't try to lookup the cache for the
18723 next/previous character if nothing is cached there yet, or if we
18724 were just reseat()'ed to a new position.
18726 * xdisp.c (set_cursor_from_row): Set start and stop points
18727 according to the row's direction when priming the loop that looks
18728 for the glyph on which to display cursor.
18729 (single_display_spec_intangible_p): Function deleted.
18730 (display_prop_intangible_p): Reimplement to call
18731 handle_display_spec instead of single_display_spec_intangible_p.
18732 Accept 3 additional arguments needed by handle_display_spec.
18733 This fixes incorrect cursor motion across display property with complex
18734 values: lists, `(when COND...)' forms, etc.
18735 (single_display_spec_string_p): Support property values that are
18736 lists with the argument STRING its top-level element.
18737 (display_prop_string_p): Fix the condition for processing a
18738 property that is a list to be consistent with handle_display_spec.
18739 (handle_display_spec): New function, refactored from the
18740 last portion of handle_display_prop.
18741 (compute_display_string_pos): Accept additional argument
18742 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18743 value of a `display' property is a "replacing spec".
18744 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18745 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18746 the display property, but just return a value indicating whether
18747 the display property will replace the characters it covers.
18748 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18749 frame_window_p members of struct bidi_it.
18750 (compute_display_string_pos, compute_display_string_end):
18752 (push_it): Accept second argument POSITION, where pop_it should
18753 jump to continue iteration.
18754 (reseat_1): Initialize bidi_it.disp_pos.
18756 * keyboard.c (adjust_point_for_property): Adjust the call to
18757 display_prop_intangible_p to its new signature.
18759 * dispextern.h (struct bidi_it): New member frame_window_p.
18760 (bidi_init_it): Update prototypes.
18761 (display_prop_intangible_p): Update prototype.
18762 (compute_display_string_pos, compute_display_string_end):
18763 Declare prototypes.
18764 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18767 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18769 Malloc failure behavior now depends on size of allocation.
18770 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18771 * lisp.h: Change signatures accordingly.
18772 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18773 All callers changed. (Bug#8762)
18775 * gnutls.c: Use Emacs's memory allocators.
18776 Without this change, the gnutls library would invoke malloc etc.
18777 directly, which causes problems on non-SYNC_INPUT hosts, and which
18778 runs afoul of improving memory_full behavior. (Bug#8761)
18779 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18780 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18781 xfree instead of the default malloc, realloc, free.
18782 (Fgnutls_boot): No need to check for memory allocation failure,
18783 since xmalloc does that for us.
18785 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18786 * category.c (hash_get_category_set):
18787 * ccl.c (ccl_driver):
18788 * charset.c (Fdefine_charset_internal):
18789 * charset.h (struct charset.hash_index):

18799 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18800 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18801 * image.c (make_image, search_image_cache, lookup_image)
18802 (xpm_put_color_table_h):
18803 * lisp.h (struct Lisp_Hash_Table):
18804 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18805 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18806 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18807 * alloc.c (allocate_vectorlike):
18808 Check for overflow in vector size calculations.
18809 * ccl.c (ccl_driver):
18810 Check for overflow when converting EMACS_INT to int.
18811 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18812 need to be updated by these changes.
18813 * fns.c (make_hash_table, maybe_resize_hash_table):
18814 Check for integer overflow with large hash tables.
18815 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18816 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18817 (SXHASH_REDUCE): New macro.
18818 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18819 Use it instead of discarding useful hash info with large hash values.
18820 (sxhash_float): New function.
18821 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18822 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18823 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18824 Rewrite to use FIXNUM_BITS, as this simplifies things.
18825 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18826 Adjust signatures to match updated version of code.
18827 (consing_since_gc): Now EMACS_INT, since a single hash table can
18828 use more than INT_MAX bytes.
18830 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18832 Make it possible to build with GCC-4.6+ -O2 -flto.
18834 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18836 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18838 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18839 Call minibuffer-inactive-mode.
18841 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18843 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18844 Update dependencies.
18846 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18848 * data.c (init_data): Remove code for UTS, this system is not
18851 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18853 Don't force ./temacs to start in terminal mode.
18855 * frame.c (make_initial_frame): Initialize faces in all cases, not
18856 only when CANNOT_DUMP is defined.
18857 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18859 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18861 * dispnew.c (add_window_display_history): Use const for the string
18862 pointer. Remove declaration, not needed.
18864 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18866 Use 'inline', not 'INLINE'.
18867 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18868 * alloc.c, fontset.c (INLINE): Remove.
18869 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18870 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18871 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18872 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18873 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18875 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18877 Make it possible to run ./temacs.
18879 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18880 syms_of_callproc does the same thing. Remove test for
18881 "initialized", do it in the caller.
18882 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18884 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18886 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18887 (read_minibuf): Use get_minibuffer.
18888 (syms_of_minibuf): Use DEFSYM.
18889 (Qmetadata): New var.
18890 * data.c (Qbuffer): Don't make it static.
18891 (syms_of_data): Use DEFSYM.
18893 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18895 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18896 (CCL_CODE_MIN): New macro.
18898 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18900 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18902 * eval.c (Qdebug): Now static.
18903 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18904 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18905 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18907 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18909 * image.c: Various fixes to ImageMagick code comments.
18910 (Fimagemagick_types): Doc fix.
18912 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18914 Minor fixes prompted by GCC 4.6.0 warnings.
18916 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18918 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18919 (x_clipboard_manager_save_all): Move extern decl to ...
18920 * xterm.h: ... here, so that it can be checked for consistency.
18922 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18924 * xselect.c (x_clipboard_manager_save_frame)
18925 (x_clipboard_manager_save_all): New functions.
18926 (Fx_clipboard_manager_save): Lisp function deleted.
18928 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18929 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18931 * xterm.h: Update prototype.
18933 2011-05-28 William Xu <william.xwl@gmail.com>
18935 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18936 exiting (Bug#8239).
18938 2011-05-28 Jim Meyering <meyering@redhat.com>
18940 Avoid a sign-extension bug in crypto_hash_function.
18941 * fns.c (to_uchar): Define.
18942 (crypto_hash_function): Use it to convert some newly-signed
18943 variables to unsigned, to avoid sign-extension bugs. For example,
18944 without this change, (md5 "truc") would evaluate to
18945 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18946 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18947 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18949 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18951 Integer overflow fixes.
18953 * dbusbind.c: Serial number integer overflow fixes.
18954 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18955 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18956 to hold a serial number that is too large for a fixnum.
18957 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18958 Check for serial numbers out of range. Decode any serial number
18959 that was so large that it became a float. (Bug#8722)
18961 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18962 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18963 Use XFASTINT rather than XUINT when numbers are nonnegative.
18964 (xd_append_arg, Fdbus_method_return_internal):
18965 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18966 arguments, check that Lisp number is nonnegative, rather than
18967 silently wrapping negative numbers around. (Bug#8722)
18968 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18971 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18973 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18975 ccl: Add integer overflow checks.
18976 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18977 (IN_INT_RANGE): New macros.
18978 (ccl_driver): Use them to check for integer overflow when
18979 decoding a CCL program. Many of the new checks are whether XINT (x)
18980 fits in int; it doesn't always, on 64-bit hosts. The new version
18981 doesn't catch all possible integer overflows, but it's an
18982 improvement. (Bug#8719)
18984 * alloc.c (make_event_array): Use XINT, not XUINT.
18985 There's no need for unsigned here.
18987 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18988 This follows up to the 2011-05-06 change that substituted uintptr_t
18989 for EMACS_INT. This case wasn't caught back then.
18991 Rework Fformat to avoid integer overflow issues.
18992 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18993 now (part of C89). Include <verify.h>.
18994 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18995 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18996 (Fformat): Avoid the prepass trying to compute sizes; it was only
18997 approximate and thus did not catch overflow reliably. Instead, walk
18998 through the format just once, formatting and computing sizes as we go,
18999 checking for integer overflow at every step, and allocating a larger
19000 buffer as needed. Keep track separately whether the format is
19001 multibyte. Keep only the most-recently calculated precision, rather
19002 than them all. Record whether each argument has been converted to
19003 string. Use EMACS_INT, not int, for byte and char and arg counts.
19004 Support field widths and precisions larger than INT_MAX. Avoid
19005 sprintf's undefined behavior with conversion specifications such as %#d
19006 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19007 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19008 formatting out-of-range floating point numbers with int
19009 formats. (Bug#8668)
19011 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19013 * data.c: Avoid integer truncation in expressions involving floats.
19014 * data.c: Include <intprops.h>.
19015 (arith_driver): When there's an integer overflow in an expression
19016 involving floating point, convert the integers to floating point
19017 so that the resulting value does not suffer from catastrophic
19018 integer truncation. For example, on a 64-bit host (* 4
19019 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19020 Do not rely on undefined behavior after integer overflow.
19022 merge count_size_as_multibyte, parse_str_to_multibyte
19023 * character.c, character.h (count_size_as_multibyte):
19024 Rename from parse_str_to_multibyte; all uses changed.
19025 Check for integer overflow.
19026 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19027 since it's now a duplicate of the other. This is more of
19028 a character than a buffer op, so better that it's in character.c.
19029 * fns.c, print.c: Adjust to above changes.
19031 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19033 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19035 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19037 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19038 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19039 (x_clipboard_manager_save): Now static.
19040 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19042 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19043 (crypto_hash_function): Now static.
19044 Fix pointer signedness problems. Avoid unnecessary initializations.
19046 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19048 * termhooks.h (Vselection_alist): Make it terminal-local.
19050 * terminal.c (create_terminal): Initialize it.
19052 * xselect.c: Support for clipboard managers.
19053 (Vselection_alist): Move to termhooks.h as terminal-local var.
19054 (LOCAL_SELECTION): New macro.
19055 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19056 (symbol_to_x_atom): Remove gratuitous arg.
19057 (x_handle_selection_request, lisp_data_to_selection_data)
19058 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19059 (x_own_selection, x_get_local_selection, x_convert_selection):
19060 New arg, specifying work frame. Use terminal-local Vselection_alist.
19061 (some_frame_on_display): Delete unused function.
19062 (Fx_own_selection_internal, Fx_get_selection_internal)
19063 (Fx_disown_selection_internal, Fx_selection_owner_p)
19064 (Fx_selection_exists_p): New optional frame arg.
19065 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19066 (x_handle_selection_clear): Don't treat other terminals with the
19067 same keyboard specially. Use the terminal-local Vselection_alist.
19068 (x_clear_frame_selections): Use Frun_hook_with_args.
19070 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19072 * xterm.h: Add support for those atoms.
19074 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19076 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19077 (converted_selections, conversion_fail_tag): New global variables.
19078 (x_selection_request_lisp_error): Free the above.
19079 (x_get_local_selection): Remove unnecessary code.
19080 (x_reply_selection_request): Args changed; handle arbitrary array
19081 of converted selections stored in converted_selections.
19082 Separate the XChangeProperty and SelectionNotify steps.
19083 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19084 (x_convert_selection): New function.
19085 (x_handle_selection_event): Simplify.
19086 (x_get_foreign_selection): Don't ignore incoming requests while
19087 waiting for an answer; this will fail when we implement
19088 SAVE_TARGETS, and seems unnecessary anyway.
19089 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19090 (Vx_sent_selection_functions): Doc fix.
19092 2011-05-26 Leo Liu <sdl.web@gmail.com>
19094 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19096 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19098 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19100 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19101 for fringe update if it has periodic bitmap.
19102 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19103 and fringe_bitmap_periodic_p.
19105 * fringe.c (get_fringe_bitmap_data): New function.
19106 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19107 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19108 row. Mark glyph row for fringe update if periodicity changed.
19110 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19111 for fringe update unless it has periodic bitmap.
19113 2011-05-25 Kenichi Handa <handa@m17n.org>
19115 * xdisp.c (get_next_display_element): Set correct it->face_id for
19116 a static composition.
19118 2011-05-24 Leo Liu <sdl.web@gmail.com>
19121 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19123 * fns.c (crypto_hash_function, Fsha1): New function.
19124 (Fmd5): Use crypto_hash_function.
19125 (syms_of_fns): Add Ssha1.
19127 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19129 * gnutls.c: Remove unused macros.
19130 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19131 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19132 Remove macros that are defined and never used.
19133 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19135 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19137 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19138 (Fx_get_selection_internal): Minor cleanup.
19139 (Fx_own_selection_internal): Rename arguments for consistency with
19142 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19144 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19146 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19148 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19150 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19152 * dispnew.c (scrolling_window): Don't exclude the case that the
19153 last enabled row in the desired matrix touches the bottom boundary.
19155 2011-05-21 Glenn Morris <rgm@gnu.org>
19157 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19158 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19159 and add some more files.
19161 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19163 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19164 report_file_error introduced by the change from 2011-05-07.
19166 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19168 * systime.h (Time): Define only if emacs is defined.
19169 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19170 where the include path doesn't have X11/X.h by default. See
19171 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19173 2011-05-20 Kenichi Handa <handa@m17n.org>
19175 * composite.c (find_automatic_composition): Fix previous change.
19177 2011-05-20 Glenn Morris <rgm@gnu.org>
19179 * lisp.mk: New file, split from Makefile.in.
19180 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19181 (shortlisp): Remove.
19182 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19184 2011-05-19 Glenn Morris <rgm@gnu.org>
19186 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19187 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19188 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19189 (lisp): Set the order to that of loadup.el.
19190 (shortlisp): Make it a copy of $lisp.
19191 (SOME_MACHINE_LISP): Remove.
19192 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19193 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19195 2011-05-18 Kenichi Handa <handa@m17n.org>
19197 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19198 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19199 (find_automatic_composition): Mostly rewrite for efficiency.
19201 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19203 * makefile.w32-in: Update dependencies.
19205 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19207 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19208 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19210 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19212 Fix some integer overflow issues, such as string length overflow.
19214 * insdel.c (count_size_as_multibyte): Check for string overflow.
19216 * character.c (lisp_string_width): Check for string overflow.
19217 Use EMACS_INT, not int, for string indexes and lengths; in
19218 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19219 the resulting string length overflows an EMACS_INT; instead,
19220 report a string overflow if no precision given. When checking for
19221 precision exhaustion, use a check that cannot possibly have
19222 integer overflow. (Bug#8675)
19223 * character.h (lisp_string_width): Adjust to new signature.
19225 * alloc.c (string_overflow): New function.
19226 (Fmake_string): Use it. This doesn't change behavior, but saves
19227 a few bytes and will simplify future changes.
19228 * character.c (string_escape_byte8): Likewise.
19229 * lisp.h (string_overflow): New decl.
19231 Fixups, following up to the user-interface timestamp change.
19232 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19233 for UI timestamps, instead of unsigned long.
19234 * msdos.c (mouse_get_pos): Likewise.
19235 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19236 * w32gui.h (Time): Define by including "systime.h" rather than by
19237 declaring it ourselves. (Bug#8664)
19239 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19240 * image.c (clear_image_cache): Likewise.
19242 * term.c (term_mouse_position): Don't assume time_t wraparound.
19244 Be more systematic about user-interface timestamps.
19245 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19246 and sometimes 'EMACS_UINT', to represent these timestamps.
19247 This change causes it to use 'Time' uniformly, as that's what X uses.
19248 This makes the code easier to follow, and makes it easier to catch
19249 integer overflow bugs such as Bug#8664.
19250 * frame.c (Fmouse_position, Fmouse_pixel_position):
19251 Use Time, not unsigned long, for user-interface timestamps.
19252 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19253 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19254 * keyboard.h (last_event_timestamp): Likewise.
19255 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19256 * menu.h (xmenu_show): Likewise.
19257 * term.c (term_mouse_position): Likewise.
19258 * termhooks.h (struct input_event.timestamp): Likewise.
19259 (struct terminal.mouse_position_hook): Likewise.
19260 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19261 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19262 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19263 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19264 what it was before.
19265 * menu.h, termhooks.h: Include "systime.h", for Time.
19267 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19268 Don't assume that the difference between two unsigned long values
19269 can fit into an integer. At this point, we know button_down_time
19270 <= event->timestamp, so the difference must be nonnegative, so
19271 there's no need to cast the result if double-click-time is
19272 nonnegative, as it should be; check that it's nonnegative, just in
19273 case. This bug is triggered when events are more than 2**31 ms
19274 apart (about 25 days). (Bug#8664)
19276 * xselect.c (last_event_timestamp): Remove duplicate decl.
19277 (x_own_selection): Remove needless cast to unsigned long.
19279 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19280 that always fit in int. Use a sentinel instead of a counter, to
19281 avoid a temp and to allay GCC's concerns about possible int overflow.
19282 * frame.h (struct frame): Use int for menu_bar_items_used
19283 instead of EMACS_INT, since it always fits in int.
19285 * menu.c (grow_menu_items): Check for int overflow.
19287 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19289 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19290 Before, the code was not consistent. These values cannot exceed
19291 2**31 - 1 so there's no need to make them unsigned.
19292 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19293 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19294 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19296 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19298 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19299 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19300 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19301 presumably because the widths might not match.
19303 * window.c (size_window): Avoid needless test at loop start.
19305 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19307 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19309 2011-05-12 Drew Adams <drew.adams@oracle.com>
19311 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19313 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19315 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19316 `width' to `bar_area_x' and `bar_area_width', respectively.
19317 (x_scroll_run): Take account of fringe background extension.
19319 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19320 Rename local vars `left' and `width' to `bar_area_x' and
19321 `bar_area_width', respectively.
19322 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19323 background extension.
19325 2011-05-10 Jim Meyering <meyering@redhat.com>
19327 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19329 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19331 * image.c (Finit_image_library): Return t for built-in image types,
19332 like pbm and xbm. (Bug#8640)
19334 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19336 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19338 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19340 * w32console.c (Fset_screen_color): Doc fix.
19341 (Fget_screen_color): New function.
19342 (syms_of_ntterm): Defsubr it.
19344 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19345 unlink the temporary file if Fcall_process didn't create it in the
19347 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19348 child process will be redirected to a file specified with `:file'.
19349 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19350 cue to call_process_cleanup not to close that handle.
19352 2011-05-07 Ben Key <bkey76@gmail.com>
19354 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19355 one of two shell specific rules, either bootstrap-temacs-CMD or
19356 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19357 to the previous implementation of the bootstrap-temacs rule.
19358 The bootstrap-temacs-CMD rule is similar to the previous
19359 implementation of the bootstrap-temacs rule except that it
19360 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19363 These changes, along with some changes to nt/configure.bat,
19364 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19365 earlier fix to add support for --cflags and --ldflags options
19366 that include quotes so that it works whether make uses cmd or
19369 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19371 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19372 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19374 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19375 a string. Handle both cases.
19376 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19377 (Fdbus_register_method): Use Qinvalid_function.
19379 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19381 * makefile.w32-in: Update dependencies.
19382 (LISP_H): Add inttypes.h and stdin.h.
19383 (PROCESS_H): Add unistd.h.
19385 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19387 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19388 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19390 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19392 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19394 * term.c (vfatal): Remove stray call to va_end.
19395 It's not needed and the C Standard doesn't allow it here anyway.
19397 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19398 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19400 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19403 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19405 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19407 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19409 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19411 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19413 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19414 * charset.c (Fdefine_charset_internal): Don't initialize
19415 charset.code_space[15]. The value was garbage, on hosts with
19416 32-bit int (Bug#8600).
19418 * lread.c (read_integer): Be more consistent with string-to-number.
19419 Use string_to_number to do the actual conversion; this avoids
19420 rounding errors and fixes some other screwups. Without this fix,
19421 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19422 (digit_to_number): Move earlier, for benefit of read_integer.
19423 Return -1 if the digit is out of range for the base, -2 if it is
19424 not a digit in any supported base. (Bug#8602)
19426 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19428 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19429 to match comment at start of function. This also removes a
19430 GCC warning about overflow in a 32+64-bit port.
19432 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19434 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19435 Reported by Stefan Monnier in
19436 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19437 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19438 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19440 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19441 (EMACS_UINTPTR): Likewise, with uintptr_t.
19443 * lisp.h: Prefer 64-bit EMACS_INT if available.
19444 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19445 on 32-bit hosts that have 64-bit int, so that they can access
19447 However, temporarily disable this change unless the temporary
19448 symbol WIDE_EMACS_INT is defined.
19450 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19452 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19453 This removes an assumption that EMACS_INT and long are the same
19454 width as pointers. The assumption is true for Emacs porting targets
19455 now, but we want to make other targets possible.
19456 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19457 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19458 In the rest of the code, change types of integers that hold casted
19459 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19460 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19461 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19462 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19463 No need to cast type when ORing.
19464 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19465 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19466 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19467 assume EMACS_INT is the same width as char *.
19468 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19469 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19470 Remove no-longer-needed casts.
19471 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19472 (xg_tool_bar_help_callback, xg_make_tool_item):
19473 Use EMACS_INTPTR to hold an integer
19474 that will be cast to void *; this can avoid a GCC warning
19475 if EMACS_INT is not the same width as void *.
19476 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19477 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19478 (current_message_1, set_message_1):
19479 Use a local to convert to proper width without a cast.
19480 * xmenu.c (dialog_selection_callback): Likewise.
19482 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19483 Also, don't assume VALBITS / RAND_BITS is less than 5,
19484 and don't rely on undefined behavior when shifting a 1 left into
19486 * lisp.h (get_random): Change signature to match.
19488 * lread.c (hash_string): Use size_t, not int, for hash computation.
19489 Normally we prefer signed values; but hashing is special, because
19490 it's better to use unsigned division on hash table sizes so that
19491 the remainder is nonnegative. Also, size_t is the natural width
19492 for hashing into memory. The previous code used 'int', which doesn't
19493 retain enough info to hash well into very large tables.
19494 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19496 * dbusbind.c: Don't possibly lose pointer info when converting.
19497 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19498 Use XPNTR rather than XHASH, so that the high-order bits of
19499 the pointer aren't lost when converting through void *.
19501 * eval.c (Fautoload): Don't double-shift a pointer.
19503 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19505 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19507 * gnutls.c (DEF_GNUTLS_FN):
19508 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19510 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19512 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19515 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19517 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19518 New version that can reserve upto 2GB of heap space.
19520 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19522 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19524 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19526 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19527 `gnutls_certificate_set_x509_key_file'.
19529 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

19586 * process.c: Include lisp.h before w32.h, not after.
19587 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19588 instead of gnutls_record_check_pending.

19592 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19594 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

19640 rather than `XVECTOR (FOO)->size'.
19642 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19643 inttypes.h, as a gnulib replacement is used if it not available in
19646 2011-04-21 Eli Zaretskii <eliz@gnu.org>

19665 %llo or %llx format is passed. (Bug#8545)
19667 * window.c (window_scroll_line_based): Use a marker instead of
19668 simple variables to record original value of point. (Bug#7952)
19670 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19671 produced by %s or %c overflows available buffer space. (Bug#8545)
19673 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19675 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19676 (SIZE_MAX): Move defn after all includes, as they might #define it.
19678 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19680 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19682 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19684 * keyboard.c (Qdelayed_warnings_hook): Define.
19685 (command_loop_1): Run `delayed-warnings-hook'
19686 if Vdelayed_warnings_list is non-nil.
19687 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19688 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19690 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19692 * doprnt.c (doprnt): Don't return value smaller than the buffer
19693 size if the message was truncated. (Bug#8545).
19695 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19697 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19698 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19700 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19702 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19704 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19706 * makefile.w32-in: Update dependencies.
19708 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19710 Improve `doprnt' and its usage. (Bug#8545)
19711 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19712 `format_end'. Remove support for %l as a conversion specifier.
19713 Don't use xrealloc. Improve diagnostics when the %l size modifier
19714 is used. Update the commentary.
19716 * eval.c (verror): Simplify calculation of size_t.
19718 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19721 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19723 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19726 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19728 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19729 This makes this file independent of the recent pseudovector change.
19731 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19733 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19735 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19736 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19737 Remove unused local.
19738 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19740 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19741 GCC 4.6.0 optimizes based on type-based alias analysis.
19742 For example, if b is of type struct buffer * and v of type struct
19743 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19744 != &v->size, and therefore "v->size = 1; b->size = 2; return
19745 v->size;" must therefore return 1. This assumption is incorrect
19746 for Emacs, since it type-puns struct Lisp_Vector * with many other
19747 types. To fix this problem, this patch adds a new type struct
19748 vectorlike_header that documents the constraints on layout of vectors
19749 and pseudovectors, and helps optimizing compilers not get fooled
19750 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19751 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19752 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19754 (XSETPVECTYPE): Rewrite in terms of new macro.
19755 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19756 This is a bit clearer, and further avoids the possibility of
19757 undesirable aliasing.
19758 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19759 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19760 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19761 since Lisp_Subr is a special case (no "next" field).
19762 (ASIZE): Now uses header.size rather than size.
19763 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19764 to avoid the hassle of writing XVECTOR (foo)->header.size.
19765 (struct vectorlike_header): New type.
19766 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19767 object, to help avoid aliasing.
19768 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19769 (SUBRP): Likewise, since Lisp_Subr is a special case.
19770 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19771 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19772 (struct Lisp_Hash_Table): Combine first two members into a single
19773 struct vectorlike_header member. All uses of "size" and "next" members
19774 changed to be "header.size" and "header.next".
19775 * buffer.h (struct buffer): Likewise.
19776 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19777 * frame.h (struct frame): Likewise.
19778 * process.h (struct Lisp_Process): Likewise.
19779 * termhooks.h (struct terminal): Likewise.
19780 * window.c (struct save_window_data, struct saved_window): Likewise.
19781 * window.h (struct window): Likewise.
19782 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19783 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19784 * buffer.c (init_buffer_once): Likewise.
19785 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19787 * process.c (Fformat_network_address): Use local var for size,
19790 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19792 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19793 * data.c (atof): Remove decl; no longer used or needed.
19794 (digit_to_number): Move to lread.c.
19795 (Fstring_to_number): Use new string_to_number function, to be
19796 consistent with how the Lisp reader treats infinities and NaNs.
19797 Do not assume that floating-point numbers represent EMACS_INT
19798 without losing information; this is not true on most 64-bit hosts.
19799 Avoid double-rounding errors, by insisting on integers when
19800 parsing non-base-10 numbers, as the documentation specifies.
19801 * lisp.h (string_to_number): New decl, replacing ...
19802 (isfloat_string): Remove.
19803 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19804 (read1): Do not accept +. and -. as integers; this
19805 appears to have been a coding error. Similarly, do not accept
19806 strings like +-1e0 as floating point numbers. Do not report
19807 overflow for integer overflows unless the base is not 10 which
19808 means we have no simple and reliable way to continue.
19809 Break out the floating-point parsing into a new
19810 function string_to_number, so that Fstring_to_number parses
19811 floating point numbers consistently with the Lisp reader.
19812 (digit_to_number): Move here from data.c. Make it static inline.
19813 (E_CHAR, EXP_INT): Remove, replacing with ...
19814 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19815 (string_to_number): New function, replacing isfloat_string.
19816 This function checks for valid syntax and produces the resulting
19817 Lisp float number too. Rework it so that string-to-number
19818 no longer mishandles examples like "1.0e+". Use strtoumax,
19819 so that overflow for non-base-10 numbers is reported only when
19820 there's no portable and simple way to convert to floating point.
19822 * textprop.c (set_text_properties_1): Rewrite for clarity,
19823 and to avoid GCC warning about integer overflow.
19825 * intervals.h (struct interval): Use EMACS_INT for members
19826 where EMACS_UINT might cause problems. See
19827 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19828 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19829 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19831 (offset_intervals): Tell GCC not to worry about length overflow
19832 when negating a negative length.
19834 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19835 (overrun_check_free): Likewise.
19837 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19838 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19841 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19842 (gnutls_make_error): Rename local to avoid shadowing.
19843 (gnutls_emacs_global_deinit): ifdef out; not used.
19844 (Fgnutls_boot): Use const for pointer to readonly storage.
19845 Comment out unused local. Fix pointer signedness problems.
19847 * lread.c (openp): Don't stuff size_t into an 'int'.
19848 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19849 about possible signed overflow.
19851 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19852 (GDK_KEY_g): Don't define if already defined.
19853 (xg_prepare_tooltip): Avoid pointer signedness problem.
19854 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19856 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19857 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19859 * xfns.c (Fx_window_property): Simplify a bit,
19860 to make a bit faster and to avoid GCC 4.6.0 warning.
19861 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19863 * fns.c (internal_equal): Don't assume size_t fits in int.
19865 * alloc.c (compact_small_strings): Tighten assertion a little.
19867 Replace pEd with more-general pI, and fix some printf arg casts.
19868 * lisp.h (pI): New macro, generalizing old pEd macro to other
19869 conversion specifiers. For example, use "...%"pI"d..." rather
19870 than "...%"pEd"...".
19871 (pEd): Remove. All uses replaced with similar uses of pI.
19872 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19873 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19874 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19875 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19876 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19877 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19878 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19880 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19881 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19882 * print.c (safe_debug_print, print_object): Likewise.
19883 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19885 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19886 avoiding the 0 flag, which is not portable.
19887 * process.c (Fmake_network_process): Use pI to avoid cast.
19888 * region-cache.c (pp_cache): Likewise.
19889 * xdisp.c (decode_mode_spec): Likewise.
19890 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19891 behavior on 64-bit hosts with printf arg.
19892 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19893 (x_stop_queuing_selection_requests): Likewise.
19894 (x_get_window_property): Don't truncate byte count to an 'int'
19897 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19898 here, since it parses constructs like leading '-' and spaces,
19899 which are not wanted; and it overflows with large numbers.
19900 Instead, simply match F[0-9]+, which is what is wanted anyway.
19902 * alloc.c: Remove unportable assumptions about struct layout.
19903 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19904 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19905 (allocate_vectorlike, make_pure_vector): Use the new macros,
19906 plus offsetof, to remove unportable assumptions about struct layout.
19907 These assumptions hold on all porting targets that I know of, but
19908 they are not guaranteed, they're easy to remove, and removing them
19909 makes further changes easier.
19911 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19912 This doesn't fix a bug but makes the code clearer.
19913 (string_overrun_cookie): Now const. Use initializers that
19914 don't formally overflow signed char, to avoid warnings.
19915 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19916 can cause Emacs to crash when string overrun checking is enabled.
19917 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19918 multiple of sizeof (EMACS_INT); it need not be, if
19919 alignof(EMACS_INT) < sizeof (EMACS_INT).
19920 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19922 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19924 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19926 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19928 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19929 supposed to be handshaking. (Bug#8556)
19930 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19932 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19934 * lisp.h (Qdebug): List symbol.
19935 * eval.c (Qdebug): Restore global linkage.
19936 * keyboard.c (debug-on-event): New variable.
19937 (handle_user_signal): Break into debugger when debug-on-event
19938 matches the current signal symbol.
19940 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19942 * alloc.c (check_sblock, check_string_bytes)
19943 (check_string_free_list): Convert to standard C.
19945 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

20503 * xfaces.c (face_at_string_position):
20504 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

20673 Declare Lisp_Object Q* variables to be 'static' if not exported.
20674 This makes it easier for human readers (and static analyzers)
20675 to see whether these variables are used from other modules.

20689 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20691 Make Emacs functions such as Fatom 'static' by default.
20692 This makes it easier for human readers (and static analyzers)
20693 to see whether these functions can be called from other modules.
20694 DEFUN now defines a static function. To make the function external
20695 so that it can be used in other C modules, use the new macro DEFUE.

20701 Remove decls, since these functions are now static.
20702 (Funintern, Fget_internal_run_time): New decls, since these functions
20703 were already external.
20705 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20713 Mark functions with DEFUE instead of DEFUN,
20714 if they are used in other modules.
20715 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20716 decls for now-static functions.
20717 * buffer.h (Fdelete_overlay): Remove decl.

20753 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20755 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20756 when at ZV. (Bug#8487)
20758 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20760 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20769 (overrun_check_free): Protoize.
20771 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20773 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20774 since callers should never pass a negative size.
20775 Change the signature to match that of plain 'read' and 'write'; see
20776 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20777 * lisp.h: Update prototypes of emacs_write and emacs_read.
20779 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20781 * xdisp.c (redisplay_window): Don't try to determine the character
20782 position of the scroll margin if the window start point w->startp
20783 is outside the buffer's accessible region. (Bug#8468)
20785 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20787 Fix write-region and its subroutines for buffers > 2GB.
20788 * fileio.c (a_write, e_write): Modify declaration of arguments and
20789 local variables to support buffers larger than 2GB.
20790 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20792 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20793 argument, local variables, and return value.
20795 * lisp.h: Update prototypes of emacs_write and emacs_read.
20797 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20799 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20801 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20803 Fix more problems found by GCC 4.6.0's static checks.
20805 * xdisp.c (vmessage): Use a better test for character truncation.
20807 * charset.c (load_charset_map): <, not <=, for optimization,
20808 and to avoid potential problems with integer overflow.
20809 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20810 * casetab.c (set_identity, shuffle): Likewise.
20811 * editfns.c (Fformat): Likewise.
20812 * syntax.c (skip_chars): Likewise.
20814 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20815 This also lets GCC 4.6.0 generate slightly better loop code.
20817 * callint.c (Fcall_interactively): <, not <=, for optimization.
20818 (Fcall_interactively): Count the number of arguments produced,
20819 not the number of arguments given. This is simpler and lets GCC
20820 4.6.0 generate slightly better code.
20822 * ftfont.c: Distingish more carefully between FcChar8 and char.
20823 The previous code passed unsigned char * to a functions like
20824 strlen and xstrcasecmp that expect char *, which does not
20825 conform to the C standard.
20826 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20827 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20828 char * when the C standard requires it.
20830 * keyboard.c (read_char): Remove unused var.
20832 * eval.c: Port to Windows vsnprintf (Bug#8435).
20833 Include <limits.h>.
20834 (SIZE_MAX): Define if the headers do not.
20835 (verror): Do not give up if vsnprintf returns a negative count.
20836 Instead, grow the buffer. This ports to Windows vsnprintf, which
20837 does not conform to C99. Problem reported by Eli Zaretskii.
20838 Also, simplify the allocation scheme, by avoiding the need for
20839 calling realloc, and removing the ALLOCATED variable.
20841 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20843 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20844 But keep the doprint source code for now, as we might revamp it
20845 and use it again (Bug#8435).
20846 * lisp.h (doprnt): Remove.
20847 * Makefile.in (base_obj): Remove doprnt.o.
20848 * deps.mk (doprnt.o): Remove.
20850 error: Print 32- and 64-bit integers portably (Bug#8435).
20851 Without this change, on typical 64-bit hosts error ("...%d...", N)
20852 was used to print both 32- and 64-bit integers N, which relied on
20853 undefined behavior.
20854 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20855 * lisp.h (error, verror): Mark as printf-like functions.
20856 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20857 Report overflow in size calculations when allocating printf buffer.
20858 Do not truncate output string at its first null byte.
20859 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20860 Truncate the output at a character boundary, since vsnprintf does not
20862 * charset.c (check_iso_charset_parameter): Convert internal
20863 character to string before calling 'error', since %c now has the
20865 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20866 overflow when computing char to be passed to 'error'. Do not
20867 pass Lisp_Object to 'error'; pass the integer instead.
20868 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20869 formatted with plain %d.
20871 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20873 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20875 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

20885 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20886 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20887 return ssize_t not "int", and use size_t as the buffer length.
20888 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20889 * gnutls.h: Update declarations.
20890 * process.c (read_process_output): Use ssize_t, to match.
20891 (send_process): Likewise.

20895 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20897 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20899 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20900 Use unsigned char, to match FcChar8 type definition.
20902 * xterm.c (handle_one_xevent):
20903 * xmenu.c (create_and_show_popup_menu):
20904 * xselect.c (x_decline_selection_request)

20907 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20909 Fix some uses of `int' instead of EMACS_INT.

20917 EMACS_INT. All callers changed.
20918 (pint2hrstr): Last argument is now EMACS_INT.

20934 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20936 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20937 (encode_invocation_designation): Last argument P_NCHARS is now
20939 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20940 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20942 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

20963 instead of using internal_with_output_to_temp_buffer.
20964 (Qhelp_form_show): New var.
20965 (syms_of_keyboard): Use DEFSYM macro.
20967 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21003 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21005 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21006 This avoids several warnings with gcc -Wstrict-overflow.
21007 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21008 directly, rather than having caller test rule sign. This avoids
21009 some unnecessary tests.
21010 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21011 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21012 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21014 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21015 (xfont_open): Avoid unnecessary tests.
21017 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21019 * composite.h, composite.c (composition_gstring_put_cache):
21020 Use EMACS_INT, not int, for length.

21023 breaking out part of COMPOSITION_DECODE_RULE.
21024 (COMPOSITION_DECODE_RULE): Use it.

21026 by using the new macro.
21028 * textprop.c (set_text_properties_1): Change while to do-while,
21029 since the condition is always true at first.
21031 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21032 (interval_deletion_adjustment): Return unsigned value.
21035 * process.c (list_processes_1, create_pty, read_process_output):

21054 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21056 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21057 (font_score): Avoid potential overflow in diff calculation.
21059 * fns.c (substring_both): Remove var that is set but not used.
21060 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21062 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21064 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21065 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21066 can always succeed if overflow has undefined behavior.
21068 * search.c (boyer_moore, wordify): Remove vars set but not used.
21069 (wordify): Omit three unnecessary tests.
21071 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21072 All callers changed. This avoids the need for an unused var.
21074 * casefiddle.c (casify_region): Remove var that is set but not used.
21076 * dired.c (file_name_completion): Remove var that is set but not used.
21078 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21080 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21081 (Finsert_file_contents): Remove unnecessary code checking fd.
21083 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21084 Check for integer overflow on size calculations.
21086 * buffer.c (Fprevious_overlay_change): Remove var that is set
21089 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21090 Remove vars that are set but not used.
21091 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21092 (timer_check_2): Mark vars as initialized.
21094 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21096 * image.c (lookup_image): Remove var that is set but not used.
21097 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21099 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21100 that are set but not used.
21102 * xfns.c (make_invisible_cursor): Don't return garbage
21103 if XCreateBitmapFromData fails (Bug#8410).
21105 * xselect.c (x_get_local_selection, x_handle_property_notify):
21106 Remove vars that are set but not used.
21108 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21109 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21111 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21112 Remove var that is set but not used.
21113 (scroll_bar_windows_size): Now size_t, not int.
21114 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21115 Check for overflow.
21117 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21118 (map_tty_color) [!defined MSDOS]: Likewise.
21120 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21122 * coding.c: Remove vars that are set but not used.
21123 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21124 All callers changed.

21126 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21127 (decode_coding_charset): Remove vars that are set but not used.
21129 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21130 that is set but not used.
21132 * print.c (print_object): Remove var that is set but not used.
21134 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21135 The gnulib version avoids calling malloc in the usual case,
21136 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21137 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21138 * filelock.c (current_lock_owner): Likewise.
21139 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21140 * sysdep.c: Include allocator.h, careadlinkat.h.
21141 (emacs_no_realloc_allocator): New static constant.
21142 (emacs_readlink): New function.
21143 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21144 ../lib/careadlinkat.h.
21146 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21148 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21149 first non-nil return value).
21151 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21153 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

21163 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21164 and thereabouts. All callers changed.
21165 (get_per_char_metric): Remove parameter `f', unused since
21166 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21168 2011-04-02 Jim Meyering <meyering@redhat.com>
21170 do not dereference NULL upon failed strdup
21171 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21172 (ns_get_family): Likewise.
21174 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21176 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21178 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21180 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

21200 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21202 * keyboard.c (eval_dyn): New fun.
21203 (menu_item_eval_property): Use it.

21207 * fns.c (concat, mapcar1): Accept byte-code-functions.
21209 * eval.c (Fsetq): Handle lexical vars.
21210 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21211 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21212 (FletX, Flet): Obey lexical binding.
21213 (Fcommandp): Handle closures.
21214 (Feval): New `lexical' arg.
21215 (eval_sub): New function extracted from Feval. Use it almost
21216 everywhere where Feval was used. Look up vars in lexical env.
21218 (Ffunctionp): Move from subr.el.
21219 (Ffuncall): Handle closures.
21220 (apply_lambda): Remove `eval_flags'.
21221 (funcall_lambda): Handle closures and new byte-code-functions.
21222 (Fspecial_variable_p): New function.
21223 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21224 but without exporting it to Lisp.
21226 * doc.c (Fdocumentation, store_function_docstring):
21227 * data.c (Finteractive_form): Handle closures.
21229 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21232 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21234 (exec_byte_code): New function extracted from Fbyte_code to handle new
21235 calling convention for byte-code-functions. Add new byte-codes.
21237 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21239 * alloc.c (Fmake_symbol): Init new `declared_special' field.

21248 (try_scrolling): Use it when setting scroll_limit.
21249 Limit scrolling to 100 screen lines.
21250 (redisplay_window): Even when falling back on "recentering",
21251 position point in the window according to scroll-conservatively,
21252 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21254 (try_scrolling): When point is above the window, allow searching
21255 as far as scroll_max, or one screenful, to compute vertical
21256 distance from PT to the scroll margin position. This prevents
21257 try_scrolling from unnecessarily failing when
21258 scroll-conservatively is set to a value slightly larger than the
21259 window height. Clean up the case of PT below the margin at bottom
21260 of window: scroll_max can no longer be INT_MAX. When aggressive
21261 scrolling is in use, don't let point enter the opposite scroll
21262 margin as result of the scroll.
21263 (syms_of_xdisp) <scroll-conservatively>: Document the
21264 threshold of 100 lines for never-recentering scrolling.

21271 (message_log_check_duplicate): Remove parameters `prev_bol' and
21272 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21273 (redisplay_internal): Remove parameter `preserve_echo_area',
21274 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21276 * indent.c (Fvertical_motion):
21277 * window.c (window_scroll_pixel_based, Frecenter):
21278 Don't pass `need_y_p' to `move_it_by_lines'.
21280 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21282 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21283 steal a few bits to be more compact.
21284 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21285 Remove unneeded casts.
21287 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21289 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21291 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21292 binding" message (bug#7967).
21294 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21296 Fix more problems found by GCC 4.6.0's static checks.
21298 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21299 Remove unused local var.
21301 * editfns.c (Fmessage_box): Remove unused local var.
21303 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21304 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21305 Omit unused local vars.
21306 * window.c (shrink_windows): Omit unused local var.
21307 * menu.c (digest_single_submenu): Omit unused local var.
21308 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21309 Omit unused local var.
21311 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21312 Don't assume string length fits in int.
21313 (keyremap_step, read_key_sequence): Use size_t for sizes.
21314 (read_key_sequence): Don't check last_real_key_start redundantly.
21316 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21317 instead of alloca (Bug#8344).
21319 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21320 (Fbacktrace_frame): Don't assume nframes fits in int.
21322 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21324 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21327 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21329 * cm.c (calccost): Turn while-do into do-while, for clarity.
21331 * keyboard.c (syms_of_keyboard): Use the same style as later
21332 in this function when indexing through an array. This also
21333 works around GCC bug 48267.
21335 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21337 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

21340 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21342 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21343 This avoids undefined behavior on integer overflow, and is a bit
21344 more convenient anyway since it is compared to a size_t variable.
21346 Variadic C functions now count arguments with size_t, not int.
21347 This avoids an unnecessary limitation on 64-bit machines, which
21348 caused (substring ...) to crash on large vectors (Bug#8344).
21349 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21350 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21351 All variadic functions and their callers changed accordingly.
21352 (struct gcpro.nvars): Now size_t, not int. All uses changed.
21353 * data.c (arith_driver, float_arith_driver): Likewise.
21354 * editfns.c (general_insert_function): Likewise.

21356 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21357 (funcall_lambda, mark_backtrace): Likewise.
21358 * fns.c (concat): Likewise.
21359 * frame.c (x_set_frame_parameters): Likewise.
21360 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21361 0 if not found, not -1. All callers changed.
21363 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21364 (stack_copy_size): Now size_t, not int.
21365 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21370 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21371 All callers changed.
21373 * lisp.h (multibyte_char_to_unibyte):
21374 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21375 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21376 * character.h (CHAR_TO_BYTE8):
21377 * cmds.c (internal_self_insert):
21378 * editfns.c (general_insert_function):
21379 * keymap.c (push_key_description):
21380 * search.c (Freplace_match):
21381 * xdisp.c (message_dolog, set_message_1): All callers changed.
21383 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21385 * keyboard.c (safe_run_hook_funcall): New function.
21386 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21387 don't set the hook to nil, but remove the offending function instead.
21388 (Qcommand_hook_internal): Remove, unused.
21389 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21390 Vcommand_hook_internal.
21392 * eval.c (enum run_hooks_condition): Remove.
21393 (funcall_nil, funcall_not): New functions.
21394 (run_hook_with_args): Call each function through a `funcall' argument.
21395 Remove `cond' argument, now redundant.
21396 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21397 (Frun_hook_with_args_until_failure): Adjust accordingly.
21398 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

21404 * print.c (strout): Remove parameter `multibyte', unused since
21405 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21407 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21408 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21409 All callers changed.
21411 * w32.c (_wsa_errlist): Use braces for struct initializers.
21413 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21414 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21415 All callers changed.
21416 (string_buffer_position): Likewise. Also, make static (it's never
21417 used outside xdisp.c).

21421 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21422 All callers changed.
21424 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21426 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21437 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21439 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21443 2011-03-27 Glenn Morris <rgm@gnu.org>
21445 * syssignal.h: Replace RETSIGTYPE with void.
21446 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21447 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21448 Replace SIGTYPE with void everywhere.

21459 * w32.c (read_unc_volume): Use parameter `henum', instead of
21460 global variable `wget_enum_handle'.
21462 * keymap.c (describe_vector): Remove parameters `indices' and
21463 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21478 * gtkutil.c (xg_maybe_add_timer):
21479 * keyboard.c (readable_events):
21480 * process.c (wait_reading_process_output):
21481 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21483 * insdel.c (adjust_markers_gap_motion):
21484 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21558 2011-03-23 Julien Danjou <julien@danjou.info>
21560 * term.c (Fsuspend_tty, Fresume_tty):
21561 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21562 * window.c (temp_output_buffer_show):
21563 * insdel.c (signal_before_change):
21564 * frame.c (Fhandle_switch_frame):
21565 * fileio.c (Fdo_auto_save):
21566 * emacs.c (Fkill_emacs):
21567 * editfns.c (save_excursion_restore):
21568 * cmds.c (internal_self_insert):
21569 * callint.c (Fcall_interactively):
21570 * buffer.c (Fkill_all_local_variables):
21571 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21573 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21574 unconditionally since it does the check itself.
21576 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21578 Fix more problems found by GCC 4.5.2's static checks.
21580 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21581 the first time through the loop, since we know p0 < p1 then.
21582 This also avoids a gcc -Wstrict-overflow warning.
21584 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21585 leading to a memory leak, possible in functions like
21586 load_charset_map_from_file that can allocate an unbounded number
21587 of objects (Bug#8318).
21589 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21590 that could (at least in theory) be that large.
21592 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21593 This is less likely to overflow, and avoids undefined behavior if
21594 overflow does occur. All callers changed. Use strtoul to scan
21595 for the unsigned long integer.
21596 (pint2hrstr): Simplify and tune code slightly.
21597 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21607 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21610 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21612 * process.c (Fmake_network_process): Use socklen_t, not int,
21613 where POSIX says socklen_t is required in portable programs.
21614 This fixes a porting bug on hosts like 64-bit HP-UX, where
21615 socklen_t is wider than int (Bug#8277).
21616 (Fmake_network_process, server_accept_connection):
21617 (wait_reading_process_output, read_process_output):
21620 * process.c: Rename or move locals to avoid shadowing.
21621 (list_processes_1, Fmake_network_process):
21622 (read_process_output_error_handler, exec_sentinel_error_handler):
21623 Rename or move locals.
21624 (Fmake_network_process): Define label "retry_connect" only if needed.
21625 (Fnetwork_interface_info): Fix pointer signedness.

21627 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21628 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21630 Make tparam.h and terminfo.c consistent.
21631 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21632 Include tparam.h instead, since it declares them.
21633 * cm.h (PC): Remove extern decl; tparam.h now does this.
21634 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21635 * terminfo.c: Include tparam.h, to check interfaces.
21636 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21637 (tparam): Adjust signature to match interface in tparam.h;
21638 this removes some undefined behavior. Check that outstring and len
21639 are zero, which they always are with Emacs.
21640 * tparam.h (PC, BC, UP): New extern decls.
21642 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21643 (xftfont_open): Rename locals to avoid shadowing.
21645 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21646 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21647 (OTF_TAG_SYM): Omit macro if not needed.

21649 (get_adstyle_property, ftfont_pattern_entity):
21650 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21651 Rename locals to avoid shadowing.
21653 * xfont.c (xfont_list_family): Mark var as initialized.
21655 * xml.c (make_dom): Now static.
21657 * composite.c (composition_compute_stop_pos): Rename local to
21659 (composition_reseat_it): Remove unused locals.
21660 (find_automatic_composition, composition_adjust_point): Likewise.
21661 (composition_update_it): Mark var as initialized.
21662 (find_automatic_composition): Mark vars as initialized,
21663 with a FIXME (Bug#8290).
21665 character.h: Rename locals to avoid shadowing.
21666 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21667 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21668 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21669 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21670 to avoid shadowing.
21672 * textprop.c (property_change_between_p): Remove; unused.
21674 * intervals.c (interval_start_pos): Now static.
21676 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21678 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21679 Rename locals to avoid shadowing.
21681 * sound.c (wav_play, au_play, Fplay_sound_internal):
21682 Fix pointer signedness.
21683 (alsa_choose_format): Remove unused local var.
21684 (wav_play): Initialize a variable to 0, to prevent undefined
21685 behavior (Bug#8278).
21687 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21689 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21691 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21692 clobbering (Bug#8298).
21693 * sysdep.c (sys_subshell): Likewise.
21694 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21696 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21697 This should get cleaned up, so that child_setup has the
21698 same signature on all platforms.
21700 * callproc.c (call_process_cleanup): Now static.
21701 (relocate_fd): Rename locals to avoid shadowing.
21703 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21705 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21706 not to be necessary, and produces flickering.
21708 2011-03-20 Glenn Morris <rgm@gnu.org>
21710 * config.in: Remove file.
21712 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21726 * xfaces.c (Fx_load_color_file):
21727 Read color file from absolute filename (bug#8250).
21729 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
21731 * makefile.w32-in: Update dependencies.
21733 2011-03-17 Eli Zaretskii <eliz@gnu.org>

21793 instead of using an uninitialized var.
21794 (font_sort_entities): Mark var as initialized.

21813 * alloc.c (mark_backtrace): Move decl from here ...
21814 * lisp.h: ... to here, so that it can be checked.
21816 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
21817 (Fdefvar): Rewrite so as not to use empty "else".

21822 * callint.c (quotify_arg, quotify_args): Now static.
21823 (Fcall_interactively): Rename locals to avoid shadowing.

21831 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21832 some of which prompt warnings from gcc -Wbad-function-cast.
21833 (Fformat_time_string, Fencode_time, Finsert_char):
21834 (Ftranslate_region_internal, Fformat):

21862 (Fmemory_limit): Cast sbrk's returned value to char *.
21864 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21865 avoids undefined behavior in theory.
21867 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21869 Use functions, not macros, for up- and down-casing (Bug#8254).
21870 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21871 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21872 to use the following functions instead of these macros.
21873 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21874 EMACS_INT, since callers assume the returned value fits in int.
21875 (upcase1): Likewise, for UPCASE_TABLE.
21876 (uppercasep, lowercasep, upcase): New static inline functions.
21877 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21883 (regex_compile, re_search_2, re_match_2_internal):
21884 Remove unused local vars.

21886 which gcc can warn about.
21887 (regex_compile, re_match_2_internal): Mark locals as initialized.
21888 (RETALLOC_IF): Define only if needed.
21889 (WORDCHAR_P): Likewise. This one is never needed, but is used
21890 only in a comment talking about a compiler bug, so put inside
21891 the #if 0 of that comment.
21892 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21893 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21896 * search.c (boyer_moore): Rename locals to avoid shadowing.

21911 Rename locals to avoid shadowing.
21912 (Fvertical_motion): Mark locals as initialized.
21914 * casefiddle.c (casify_object, casify_region): Now static.
21915 (casify_region): Mark local as initialized.

21919 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21920 New macros, so that the caller can use some names other than
21921 gcpro1, gcpro2, etc.
21922 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21924 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21925 argument, for consistency with GCPRO2_VAR, etc: it is now the
21926 prefix of the variable, not the variable itself. All uses
21928 * dired.c (directory_files_internal, file_name_completion):
21929 Rename locals to avoid shadowing.
21931 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21932 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21933 dired.c's scmp function, had undefined behavior.
21934 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21935 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21936 * buffer.h: ... to here, because these macros use current_buffer,
21937 and the new implementation with inline functions needs to have
21938 current_buffer in scope now, rather than later when the macros
21940 (downcase, upcase1): New static inline functions.
21941 (DOWNCASE, UPCASE1): Reimplement using these functions.
21942 This avoids undefined behavior in expressions like
21943 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21944 from race conditions in accessing the global variables
21945 case_temp1 and case_temp2.
21946 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21947 * lisp.h (case_temp1, case_temp2): Remove their decls.
21948 * character.h (ASCII_CHAR_P): Move from here ...
21949 * lisp.h: ... to here, so that the inline functions mentioned
21950 above can use them.
21952 * dired.c (directory_files_internal_unwind): Now static.
21954 * fileio.c (file_name_as_directory, directory_file_name):
21955 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21957 (file_name_as_directory): Use const pointers when appropriate.
21958 (Fexpand_file_name): Likewise. In particular, newdir might
21959 point at constant storage, so make it a const pointer.
21960 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21961 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21963 (Fset_file_times, Finsert_file_contents, auto_save_error):
21964 Rename locals to avoid shadowing.

21967 (Ftry_completion, Fall_completions): Rename or remove locals
21968 to avoid shadowing.
21970 * marker.c (bytepos_to_charpos): Remove; unused.
21972 * lisp.h (verify_bytepos, count_markers): New decls,
21973 so that gcc does not warn that these functions aren't declared.
21975 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21976 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21977 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21978 (copy_text): Remove unused local var.
21980 * filelock.c (within_one_second): Now static.
21981 (lock_file_1): Rename local to avoid shadowing.
21983 * buffer.c (fix_overlays_before): Mark locals as initialized.
21984 (fix_start_end_in_overlays): Likewise. This function should be
21985 simplified by using pointers-to-pointers, but that's a different
21987 (switch_to_buffer_1): Now static.
21988 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21989 (report_overlay_modification): Rename locals to avoid shadowing.
21991 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21992 Fix pointer signedness issue.
21993 (sys_subshell): Mark local as volatile if checking for lint,
21994 to suppress a gcc -Wclobbered warning that does not seem to be right.
21995 (MAXPATHLEN): Define only if needed.
21997 * process.c (serial_open, serial_configure): Move decls from here ...
21998 * systty.h: ... to here, so that they can be checked.
22000 * fns.c (get_random, seed_random): Move extern decls from here ...
22001 * lisp.h: ... to here, so that they can be checked.
22003 * sysdep.c (reset_io): Now static.
22004 (wait_for_termination_signal): Remove; unused.
22006 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22007 (copy_keymap_item, append_key, push_text_char_description):
22009 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22010 (DENSE_TABLE_SIZE): Remove; unused.
22011 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22012 (describe_map_tree):
22013 Rename locals to avoid shadowing.
22015 * keyboard.c: Declare functions static if they are not used elsewhere.
22016 (echo_char, echo_dash, cmd_error, top_level_2):
22017 (poll_for_input, handle_async_input): Now static.
22018 (read_char, kbd_buffer_get_event, make_lispy_position):
22019 (make_lispy_event, make_lispy_movement, apply_modifiers):
22020 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
22021 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
22022 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
22023 (read_key_sequence, read_char): Mark locals as initialized.

22100 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22101 These macros can no longer be used for assignment.
22103 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

22159 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
22161 Improve quality of tests for time stamp overflow.
22162 For example, without this patch (encode-time 0 0 0 1 1
22163 1152921504606846976) returns the obviously-bogus value (-948597
22164 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22165 reports time overflow. See
22166 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
22167 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
