3 * textprop.c (Fadd_text_properties, Fremove_text_properties)
4 (Fremove_list_of_text_properties): Skip all of the intervals in
5 the region between START and END that already have resp. don't
6 have the requested properties, not just the first one. Add
7 assertions that the loop afterwards always modifies the
8 properties. (Bug#13743)
10 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
12 * callint.c (Fcall_interactively): Use the right lexical environment
13 for `interactive' specs (bug#13811).

40 so simplify-away some unnecessary exactness.
41 (POINTER): Remove; all uses removed.
42 (data_space_start): Now char *, to avoid casts.
43 (exceeds_lisp_ptr): New function, replacing the old
44 EXCEEDS_LISP_PTR macro. All uses changed.

63 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
66 * ralloc.c (SIZE, POINTER, NIL):
67 * vm-limit.c (POINTER):
68 Remove, replacing all uses with C89 equivalents. These old
69 symbols were present only for porting to pre-C89 platforms.
71 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
73 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
74 This avoids warning messages reported as part of Bug#13546.
76 2013-02-21 Ken Brown <kbrown@cornell.edu>
78 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

89 2013-02-19 Daniel Colascione <dancol@dancol.org>
91 * sheap.c (report_sheap_usage): Use message, not message1, so
92 that we don't try to create a buffer while we're in the middle
93 of dumping Emacs. Explain why.
95 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
96 * search.c (find_newline): Return byte position in bytepos.

143 unconditionally. (Bug#9066)
145 * w32.c (set_errno): Reset h_errno and don't set it to any other

191 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
193 Fix AIX port (Bug#13650).
194 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
195 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
196 was #undeffed earlier, so it cannot be used as a macro here.
197 Use the constant and not the macro.
199 2013-02-15 Eli Zaretskii <eliz@gnu.org>
201 * w32proc.c (new_child): If no vacant slots are found in
202 child_procs[], make another pass looking for slots whose process

206 MAXDESC, set errno to EMFILE.
207 (_sys_read_ahead): Update cp->status when failing to read serial
208 communications input, so that the status doesn't stay at
209 STATUS_READ_IN_PROGRESS. (Bug#13546)
211 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
213 * gtkutil.c (tb_size_cb): New function.
214 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

221 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
223 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
225 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

233 2013-02-13 Glenn Morris <rgm@gnu.org>
235 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
237 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
239 Improve AIX port some more (Bug#13650).
240 With this, it should be as good as it was in 23.3, though it's
241 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
242 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
243 * unexaix.c (start_of_text): Remove.
244 (_data, _text): Declare as char[], not int, as AIX manual suggests.
245 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
246 (orig_load_scnptr, orig_data_scnptr):
247 Now off_t, not long, since they are file offsets.
248 (make_hdr): Use _data, not start_of_data ().
249 This is the key part of the fix.
250 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
251 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
253 * pre-crt0.c (data_start): Initialize to 1.
254 This ports to compilers that optimize the external declaration
255 'int x = 0;' as if it were 'int x;' to shrink the executable.
257 Improve AIX port (Bug#13650).
258 This doesn't fix the bug, but it makes progress: Emacs builds now.
259 * unexaix.c: Include inttypes.h, stdarg.h.
260 (report_error, report_error_1): Mark as _Noreturn.
261 (report_error): Don't report the wrong errno.
262 (report_error_1): Now varargs. All callers changed.
263 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
264 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
265 (write_ptr): Use %p to print address rather than %lx and a cast
266 to unsigned long. Grow buffer a bit, to be safer.
268 2013-02-13 Eli Zaretskii <eliz@gnu.org>
270 * bidi.c (bidi_resolve_neutral): After finding the next
271 non-neutral character, accept NEUTRAL_ON type as well, because
272 directional control characters, such as LRE and RLE, have their
273 type converted to that by bidi_resolve_weak. This avoids aborts
274 when LRE/RLE follows a run of neutrals.
275 (bidi_move_to_visually_next): Assert that return value of
276 bidi_peek_at_next_level is non-negative. Negative values will
279 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
281 Minor getenv-related fixes.
282 * callproc.c (Fcall_process_region) [!DOS_NT]:

287 Omit unnecessary cast of getenv or egetenv.
289 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
291 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
294 2013-02-12 Eli Zaretskii <eliz@gnu.org>
296 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
298 (display_line): Set w->region_showing to the value of
299 it->region_beg_charpos, not to -1. This fixes redisplay
300 optimization when cursor is moved up after M->. (Bug#13623)
302 (try_scrolling): Scroll text up more if point is too close to ZV
303 and inside the scroll margin. This makes sure point is moved
304 outside the scroll margin in these cases.
306 * window.h (struct window): region_showing can no longer be
309 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
311 Tune by using memchr and memrchr.
312 * doc.c (Fsnarf_documentation):
313 * fileio.c (Fsubstitute_in_file_name):
314 * search.c (find_newline, scan_newline):
315 * xdisp.c (pos_visible_p, display_count_lines):
316 Use memchr and memrchr rather than scanning byte-by-byte.
317 * search.c (find_newline): Rename from scan_buffer.
318 Omit first arg TARGET, as it's always '\n'. All callers changed.
320 Clean up read_key_sequence a tiny bit more.
321 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
322 (read_key_sequence): Remove unused locals.
324 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
326 Clean up read_key_sequence a bit; reread active keymaps after first event.
327 * keyboard.c (read_char, read_char_x_menu_prompt)
328 (read_char_minibuf_menu_prompt):
329 Replace nmaps+maps with a single `map' arg.
330 (follow_key): Operate on a single map.
331 (active_maps): New function.
332 (test_undefined): Also return true for nil bindings.
333 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
334 a single (composed) keymap. Remember `first_event' to choose the right
335 set of active keymaps. Recompute the set of keymaps after receiving
336 the first event. Remove GOBBLE_FIRST_EVENT.
337 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
338 * keyboard.h (read_char): Update declaration.
339 * lread.c (read_filtered_event): Adjust call to read_char.
341 2013-02-11 Eli Zaretskii <eliz@gnu.org>
343 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
344 Don't use the limitation on backwards movement when lines are truncated
345 in the window. (Bug#13675)
347 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
349 * marker.c (set_marker_internal): If desired position is passed
350 as a marker, avoid call to buf_charpos_to_bytepos.
351 * window.c (Fset_window_point): Omit redundant type checking.
352 (Fset_window_start): Likewise. Format comment.
353 (window_scroll_pixel_based): Use set_marker_restricted_both
354 with character and byte positions obtained from an iterator.
355 (Fset_window_configuration): Use set_marker_restricted_both.
356 * xdisp.c (message_dolog): Likewise.
358 2013-02-10 Eli Zaretskii <eliz@gnu.org>
360 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
361 When text lines are longer than window's screen lines, don't move back
362 too far. This speeds up some redisplay operations. (Bug#13675)
364 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
366 * syntax.c (scan_sexps_forward): Fix byte position calculation
367 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.

371 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
374 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
376 Minor hashing refactoring.
377 * fns.c (SXHASH_REDUCE): Move to lisp.h.
378 (sxhash_float): Return EMACS_UINT, for consistency with the other
380 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
381 non-static inline function and therefore can't use static vars.
382 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
383 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
384 with the other hash functions.
386 2013-02-09 Eli Zaretskii <eliz@gnu.org>
388 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
389 XXXXXX part of the temporary file pattern is not downcased even
390 when w32-downcase-file-names is non-nil. (Bug#13661)
392 * xdisp.c (decode_mode_spec): Remove handling of %t.
394 * msdos.c (careadlinkatcwd): Remove.
396 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>

480 * xdisp.c (window_buffer_changed): region_showing can be negative,
481 which still means region is being displayed.
482 (redisplay_internal): Resurrect code that forced redisplay of the
483 whole window when showing region and the mark has changed.
484 Record the new mark position to allow redisplay optimizations.
485 (display_line): If it->region_beg_charpos is non-zero, set the
486 window's region_showing member to -1. (Bug#13623) (Bug#13626)
488 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
489 not bitfield of 1 bit.
491 2013-02-03 Daniel Colascione <dancol@dancol.org>
493 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
494 daemon mode works on cygw32 when Emacs is installed and not just
497 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
499 Avoid file time stamp bug on MS-Windows (Bug#13149).
500 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
501 as FAT32 doesn't update time stamps when truncating them.
502 Also, check that a file time stamp is not a multiple of 100 ns;
503 this should catch all instances of the problem on MS-Windows,
504 as its native file system resolution is 100 ns or worse, and
505 checking for a non-multiple of 100 ns should impose only a small
506 overhead on systems with ns resolution.
508 2013-02-02 Eli Zaretskii <eliz@gnu.org>
510 Avoid encoding file names on MS-Windows when they need to be run
511 through dostounix_filename.
512 * w32.c (normalize_filename): Accept an additional argument
513 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
514 downcase it even if w32-downcase-file-names is non-nil.
515 (dostounix_filename): Accept an additional argument MULTIBYTE and
516 pass it to normalize_filename.
517 (emacs_root_dir): Adjust.
519 * msdos.h (dostounix_filename): Adjust prototype.
521 * w32.h (dostounix_filename): Adjust prototype.
523 * msdos.c (dostounix_filename): Accept an additional argument and
525 (init_environment): Adjust callers of dostounix_filename.
527 * fileio.c (Ffile_name_directory, file_name_as_directory)
528 (directory_file_name, Fexpand_file_name)
529 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
531 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
533 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
534 variables, as egetenv is case-insensitive for DOS_NT.
536 * dired.c (file_name_completion): Don't call Fdirectory_file_name
537 with an encoded file name.
539 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
540 Adjust calls to dostounix_filename.
542 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
544 * unexw32.c (unexec): Adjust call to dostounix_filename.
546 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
548 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
551 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
554 * callproc.c (Fcall_process): Make sure program name in PATH and
555 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
556 is passed to exec/spawnve, which fails unless the file-name
559 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
560 even if w32-quote-process-args is nil.
562 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
564 Fix timestamp bug when write-region appends nothing (Bug#13149).
565 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
566 the file's time stamp doesn't change if Emacs happens to write nothing
567 to the file, and on a buggy file system this could cause Emacs to
568 incorrectly infer that the file system doesn't have the bug.
569 Avoid this problem by inhibiting the inference in this case.
571 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
573 * window.h (struct window): Convert base_line_number, base_line_pos
574 and column_number_displayed members from Lisp_Object to ptrdiff_t.
575 Convert region_showing member from Lisp_Object to bitfield.
576 Remove sequence_number member. Adjust comments.
577 * window.c (sequence_number): Remove.
578 (make_window): Initialize column_number_displayed.
579 * print.c (print_object): Follow the printed representation of
580 frames and print window pointer to distinguish between windows.
581 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
582 * xdisp.c (wset_base_line_number, wset_base_line_pos)
583 (wset_column_number_displayed, wset_region_showing): Remove.
584 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
585 (try_scrolling, try_cursor_movement, redisplay_window)
586 (try_window_reusing_current_matrix, try_window_id, display_line)
587 (display_mode_lines, decode_mode_spec): Adjust users.
588 * .gdbinit (pwinx): Do not print sequence_number.
590 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
592 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
593 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
594 * dired.c: Include <fcntl.h>.
595 (open_directory): New function, which uses open and fdopendir
596 rather than opendir. DOS_NT platforms still use opendir, though.
597 (directory_files_internal, file_name_completion): Use it.
598 (file_attributes): New function, with most of the old Ffile_attributes.
599 (directory_files_internal, Ffile_attributes): Use it.
600 (file_attributes, file_name_completion_stat): First arg is now fd,
601 not dir name. All uses changed. Use fstatat rather than lstat +
603 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
604 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
605 (emacs_readlinkat): New function, with much of the old
606 Ffile_symlink_p, but with an fd argument for speed.
607 It uses readlinkat rather than careadlinkatcwd, so that it
608 need not assume the working directory.
609 (Ffile_symlink_p): Use it.
610 * filelock.c (current_lock_owner): Use emacs_readlinkat
611 rather than emacs_readlink.
612 * lisp.h (emacs_readlinkat): New decl.
613 (READLINK_BUFSIZE, emacs_readlink): Remove.
614 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
615 (emacs_norealloc_allocator, emacs_readlink): Remove.
616 This stuff is moved to fileio.c.
617 * w32.c (fstatat, readlinkat): New functions.
618 (careadlinkat): Don't check that fd == AT_FDCWD.
619 (careadlinkatcwd): Remove; no longer needed.
621 2013-01-31 Glenn Morris <rgm@gnu.org>
623 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
624 (Fwrite_region): Update for new choose_write_coding_system args.
625 Move the last piece of choose_write_coding_system here. (Bug#13522)
626 (syms_of_fileio): Add choose-write-coding-system.
628 2013-01-30 Eli Zaretskii <eliz@gnu.org>
630 * w32.c (sys_open): Zero out the flags for the new file descriptor.
631 (sys_close): Zero out the flags for the file descriptor before
632 closing it. (Bug#13546)
634 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
635 (logon_network_drive, stat_worker, symlink, chase_symlinks):
636 Use CharNextExA and CharPrevExA to iterate over file names encoded in
639 * w32.c (w32_get_long_filename, init_environment, readlink):
640 Support file names encoded in DBCS codepages.
641 (readlink): Use the current file-name-coding-system, not the ANSI
642 codepage, to decode and handle targets of symlinks.
644 2013-01-28 Eli Zaretskii <eliz@gnu.org>
646 * w32.c (opendir): Now accepts a 'const char *'.
648 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
650 Remove obsolete redisplay code. See the discussion at
651 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
652 * dispnew.c (preemption_period, preemption_next_check): Remove.
653 (Vredisplay_preemption_period): Likewise.
654 (update_frame, update_single_window, update_window, update_frame_1):
655 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
656 used, following the 2012-06-22 change.
658 2013-01-25 Eli Zaretskii <eliz@gnu.org>
660 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
662 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
664 * font.c (num_fonts): Remove the leftover from old
665 debugging code. Adjust comment style here and there.
666 * insdel.c (insert_1): Remove.
667 * lisp.h (insert_1): Remove prototype.
668 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
670 2013-01-25 Eli Zaretskii <eliz@gnu.org>
672 * w32.c (max_filename_mbslen): New function.
673 (normalize_filename, readdir): Use it to detect locales where ANSI
674 encoding of file names uses a double-byte character set (DBCS).
675 If a DBCS encoding is used, advance by characters using
676 CharNextExA, instead of incrementing a 'char *' pointer.
677 Use _mbslwr instead of _strlwr. (Bug#13515)
679 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
680 request of memory reservation to 1.7GB. (Bug#13065)
682 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
684 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
685 at check_extra_latin label. (Bug#13505)
687 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
689 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
690 Avoid redundant calls to strlen.
692 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
694 Drop async_visible and async_iconified fields of struct frame.
695 This is possible because async input is gone; for details, see
696 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
697 * frame.h (struct frame): Remove async_visible and async_iconified
698 members, convert garbaged to unsigned bitfield. Adjust comments.
699 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
700 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
701 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
702 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
703 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
705 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
706 properly. Likewise for obscured.
708 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
711 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
713 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
715 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
716 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
718 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
720 * xdisp.c (message2, message2_nolog): Remove functions.
721 (message3, message3_nolog): Extract nbytes and multibyteness directly
722 from the string. Change all callers.
723 (message3_nolog): Don't set message_enable_multibyte since set_message
724 will reset it anyway.
725 (message1, message1_nolog): Use message3.
726 (vmessage): Use a stack allocated buffer rather than f->message_buf.
727 (with_echo_area_buffer): Remove last two arguments. Update all callers.
728 (set_message): Drop all but the second arg, which has to be a string.
729 (set_message_1): Simplify now that we know that a1 is NULL and the
730 second arg is a string.
731 * frame.h (struct frame): Remove `message_buf' field.
732 Use glyphs_initialized_p instead.
733 (FRAME_MESSAGE_BUF): Remove macro.
734 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
735 * lisp.h (message2, message2_nolog): Remove declarations.
736 (message3, message3_nolog): Update declarations.
737 * keyboard.c (read_char_minibuf_menu_text)
738 (read_char_minibuf_menu_width): Remove vars.
739 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
740 to correctly handle multibyte strings.
741 * frame.c (delete_frame): Don't free message_buf any more.
742 * editfns.c (message_text, message_length): Remove vars.
743 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
744 * fileio.c (auto_save_error): Use message3 instead of message2.
745 * dispnew.c (adjust_frame_message_buffer): Remove function.
747 2013-01-23 Eli Zaretskii <eliz@gnu.org>
749 * w32term.c (w32fullscreen_hook): Account correctly for the screen
750 real estate used for the tool bar and the menu bar.
752 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
754 * insdel.c (prepare_to_modify_buffer): Force redisplay if
755 hidden buffer is prepared to modification (Bug#13164).
757 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
759 * window.h (struct window): Change window_end_valid member from
760 Lisp_Object to a bitfield. Adjust comments.
761 (wset_window_end_valid): Remove.
762 * window.c (adjust_window_count): Clear window_end_valid.
763 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
764 (Fwindow_line_height, set_window_buffer, Frecenter)
765 (Fsplit_window_internal, Fdelete_other_windows_internal)
766 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
767 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
768 * xdisp.c (check_window_end, reconsider_clip_changes)
769 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
770 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
771 (find_first_unchanged_at_end_row, try_window_id): Likewise.
773 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
775 * xdisp.c (mark_window_display_accurate): Simplify the loop
776 assuming that the only one of vchild, hchild or buffer window
777 slots is non-nil. Call mark_window_display_accurate_1 for
778 the leaf windows only.
779 (mark_window_display_accurate_1): Always assume leaf window.
782 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
784 * emacs.c (Qkill_emacs_hook): Now static.
786 * fileio.c (Finsert_file_contents): Simplify.
787 Remove unnecessary assignments and tests.
789 2013-01-21 Eli Zaretskii <eliz@gnu.org>
791 * w32.c (acl_set_file): Don't test for errors unless
792 set_file_security returns FALSE. Avoids spurious errors when
795 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
797 * fileio.c (Finsert_file_contents): Revert code introduced at
798 2013-01-18 in favor of the simpler and generally better fix.
799 Save stack space by removing 'buffer' and reusing 'read_buf'
802 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
804 * lisp.h (eabs): Define unconditionally (Bug#13419).
805 The old "#if !defined (eabs)" was an unnecessary revenant of back
806 when this macro was called "abs". Document 'eabs' better.
808 2013-01-19 Glenn Morris <rgm@gnu.org>
810 * fns.c (Frandom): Doc fix.
812 2013-01-19 Eli Zaretskii <eliz@gnu.org>
814 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
815 segfault when there are lots of overlays.
817 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
818 when there are lots of overlays.
819 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
820 for the details and a way to reproduce.
822 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
824 * fileio.c: Use O_APPEND to append.
825 This corresponds better to the natural interpretation of "append",
826 and avoids the need to open the output file twice, or to invoke
827 lseek when APPEND is neither nil nor a number.
828 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
829 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
830 file possibly twice, and lseeking to its end; this avoids the
831 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
832 at the same time: the combination is never needed and apparently
833 it doesn't work with DOS_NT.
835 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
836 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
838 Allow floating-point file offsets.
839 Problem reported by Vitalie Spinu in
840 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
841 * fileio.c (emacs_lseek): Remove.
842 (file_offset): New function.
843 (Finsert_file_contents, Fwrite_region): Use it.
845 2013-01-19 Chong Yidong <cyd@gnu.org>
847 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
848 aborting on Fsignal (Bug#13289).
850 2013-01-19 Eli Zaretskii <eliz@gnu.org>
852 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
853 set_file_security as failure due to insufficient privileges.
854 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
855 (fstat): Return owner and group like 'stat' and 'lstat' do.
857 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
859 Work around bug in CIFS and vboxsf file systems (Bug#13149).
860 The bug was observed on Ubuntu operating inside a virtual machine,
861 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
862 The workaround introduces a race condition on non-buggy hosts,
863 but it's an unlikely race and anyway there's a nearly identical
864 nearby race that can't be fixed.
865 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
867 (Fwrite_region): Test for file system time stamp bug.
868 (init_fileio): New function.
869 * lisp.h (init_fileio): Declare it.
870 * emacs.c (main): Call it.
872 * fileio.c (Finsert_file_contents): Simplify new diagnostic
873 and make it more consistent with other stat-failure diagnostics.
875 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
877 Fix crash when inserting data from non-regular files.
878 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
879 for the error description produced by valgrind.
880 * fileio.c (read_non_regular): Rename to read_contents.
881 Free Lisp_Save_Value object used to pass parameters.
882 (read_non_regular_quit): Rename to read_contents_quit.
883 (Finsert_file_contents): Redesign internal file reading loop to adjust
884 gap and end positions after each read and so help make_gap to work
885 properly. Do not signal an I/O error too early and so do not leave
886 not yet decoded characters in a buffer, which was the reason of
887 redisplay crash. Use list2 to build return value. Adjust comments.
889 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
891 Close a race when statting and reading files (Bug#13149).
892 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
893 This avoids a race if the file is renamed between stat and open.
894 This race is not the problem originally noted in Bug#13149;
895 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
897 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
899 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
900 objects, related functions and macros.
901 (make_save_value): Adjust prototype.
902 (make_save_pointer): New prototype.
903 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
904 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
905 * alloc.c (format_save_value): Rename to make_save_value.
906 (make_save_pointer): New function.
907 (record_xmalloc): Use make_save_pointer.
908 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
909 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
910 Change users of make_save_value to make_save_pointer.
911 Likewise for format_save_value and make_save_value.
913 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
915 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
916 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
917 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
920 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
922 * alloc.c (free_save_value): Now static.
924 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
926 * keymap.c (map_keymap_internal): Use format_save_value.
927 (map_keymap_char_table_item): Adjust accordingly.
928 * fileio.c (non_regular_fd, non_regular_inserted)
929 (non_regular_nbytes): Remove.
930 (Finsert_file_contents): Convert trytry to ptrdiff_t.
931 Use format_save_value to pass parameters to read_non_regular.
932 (read_non_regular): Use XSAVE_ macros to extract parameters.
934 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
936 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
938 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
940 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
941 extraction from any Lisp_Save_Value slot. Add type checking.
942 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
943 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
944 * xselect.c: All users changed.

994 * editfns.c (save_excursion_save): Pack everything within
995 Lisp_Save_Value and so avoid xmalloc.
996 (save_excursion_restore): Adjust to match new layout. Use free_misc
997 because we do not allocate extra memory any more. Add eassert.
998 * print.c (print_object): New code to print Lisp_Save_Value. Do not
999 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1013 Fix SIGDANGER handlers, for AIX (Bug#13408).
1014 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1067 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1069 Avoid unnecessary byte position calculation for the gap movement.
1070 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1081 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1083 * term.c (init_tty): Use them instead of rolling our own code.
1084 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1085 switches from 'signal' to 'pthread_sigmask', which is safer in
1086 multithreaded applications.
1087 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1088 which has already arranged for that.
1089 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1090 This is the main part of the bug fix.

1102 predicate, which is how it's really used now. Adjust comment.
1103 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1104 * buffer.c (buffer_slot_type_mismatch): Remove.
1105 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1106 predicate. Adjust comment.

1108 fill-column, left-margin, tab-width, buffer-saved-size,
1109 left-margin-width, right-margin-width, left-fringe-width,
1110 right-fringe-width, scroll-bar-width and buffer-display-count.
1111 Use Qstringp for default-directory, buffer-file-name,
1112 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1113 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1115 * data.c (store_symval_forwarding): Adjust to call the predicate.

1132 (make_gap_1): New function to adjust the gap of any buffer.
1133 * coding.c (coding_alloc_by_making_gap): Use it.
1134 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1158 trailing dash is properly added.
1160 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1162 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1163 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1164 digits for buffer positions, before misalignment starts.
1165 Display "0" for integer "object" field.
1166 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1167 Display the newline glyph more unambiguously.
1169 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1171 * nsterm.m (ns_draw_underwave):
1172 * w32term.c (w32_draw_underwave):
1173 * xterm.c (x_draw_underwave): Make underwave look more triangular
1174 and also degrade gracefully for small fonts. (Bug#13000)
1176 * nsterm.m (ns_draw_text_decoration):
1177 * w32term.c (x_draw_glyph_string):
1178 * xterm.c (x_draw_glyph_string): Don't use previous underline
1179 thickness and position if previous underline type is underwave.
1181 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1183 * fileio.c (Ffile_acl): Undocument return format.
1185 2013-01-02 Glenn Morris <rgm@gnu.org>
1187 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

1197 * lread.c (read_list):
1198 * minibuf.c (Ftry_completion):
1199 * term.c (tty_ins_del_lines):
1200 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1201 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1203 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1205 * w32.c (unsetenv): Set up the string passed to _putenv
1207 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1208 for the bug this caused.
1210 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1212 * coding.c (Qmac): Now static.
1214 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1216 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1217 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1219 toolbar_is_packed to true.
1220 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
1221 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1222 Show all on TOOLBAR_TOP_WIDGET.
1223 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1224 by TOOLBAR_TOP_WIDGET.
1225 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1226 Check toolbar_is_packed.
1227 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1228 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1229 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1231 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1232 (xg_update_menubar): Update title only if
1233 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1234 (xg_update_submenu): Skip tearoff only if
1235 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1236 (xg_initialize): Initialize xg_detached_menus only if
1237 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1239 * xterm.h (struct x_output): Surround handlebox_widget with
1240 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1241 toolbar_in_hbox is bool.
1243 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1245 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1246 (LIBS_GNUSTEP): Define.
1247 (LIBES): Add $(LIBS_GNUSTEP).
1248 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1250 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1252 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1253 continuation glyph on a TTY with an indication of an empty line.
1256 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1258 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1259 file's SELinux context or ACLs successfully set, nil otherwise.
1261 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1263 * w32proc.c (reader_thread): Avoid passing NULL handles to
1264 SetEvent and WaitForSingleObject.
1266 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1268 Port EXTERNALLY_VISIBLE to Clang 3.2.
1269 * conf_post.h (__has_attribute): New macro.
1270 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1272 2012-12-27 Glenn Morris <rgm@gnu.org>
1274 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1275 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1277 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1279 * fileio.c (file_name_as_directory, directory_file_name):
1280 Accept an additional argument MULTIBYTE to indicate whether the input C
1281 came from a multibyte or a unibyte Lisp string; all callers
1282 adjusted. Don't assume the input string is always multibyte.
1284 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1285 don't ENCODE_FILE them, and return a unibyte string if the input
1287 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1288 don't assume the input strings will always be multibyte. If the
1289 input strings are multibyte, decode strings obtained from C
1292 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1294 * lisp.h (toplevel): Add two notices to the comment about
1295 defining a new Lisp data type.

1299 * alloc.c (valid_lisp_object_p): Adjust comment.
1301 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1303 * keyboard.c (record_asynch_buffer_change): Initialize an event
1304 only if it's really needed.
1305 * frame.h (enum output_method): Remove output_mac member since
1306 it's a leftover from the deleted code.
1307 * frame.c (Fframep): Adjust user here ...
1308 * terminal.c (Fterminal_live_p): ... and here.
1309 * coding.c (Qmac): Now here because it's only used to denote
1310 end-of-line encoding type.
1311 (syms_of_coding): DEFSYM it.
1312 * frame.h (Qmac): Remove duplicated declaration.
1314 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1316 * window.c (select_window_1): Now static, since it's used only here.
1318 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1320 * window.c (window_body_cols): Subtract display margins from the
1321 window body width on TTYs as well. See
1322 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1323 for the original report.
1325 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1327 * xdisp.c (redisplay_window): Remove inner local variable
1328 because the outer shadowed one has the same meaning.
1329 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1331 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1332 (xg_create_tool_bar): Adjust users.
1334 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1336 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1337 * buffer.c (Fget_buffer_create): Use it to set compact field of
1338 struct buffer_text to avoid accessing an uninitialized value
1339 when compact_buffer is called for the first time.
1340 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1341 (Fset_buffer_modified_p): Use buffer_window_count to check
1342 whether the buffer is displayed in some window.
1343 * xdisp.c (message_dolog): Likewise.
1345 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1347 * w32.c (acl_set_file): If setting the file security descriptor
1348 fails, and the new DACL is identical to the existing one, silently
1349 return success. This fixes problems for users backing up their
1350 own files without having the necessary privileges for setting
1351 security descriptors.
1353 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1355 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1356 after WaitForSingleObject returns normally. This expedites reader
1357 thread shutdown when delete_child triggers it.
1358 (reap_subprocess): More accurate commentary for why we call
1359 delete_child only when cp->fd is negative.
1361 * w32.c (sys_close): Do not call delete_child on a subprocess
1362 whose handle is not yet closed. Instead, set its file descriptor
1363 to a negative value, so that reap_subprocess will call
1364 delete_child on that subprocess when its SIGCHLD arrives.
1365 This avoids closing handles used for communications between sys_select
1366 and reader_thread, which doesn't give sys_select a chance to
1367 notice that the process exited and invoke the SIGCHLD handler for
1370 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1372 * nsfns.m (Fns_do_applescript): Run event loop until script has
1373 been executed (Bug#12969).
1374 (ns_run_ascript): Chech as_script for nil, set to nil after
1377 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1379 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1381 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1383 * w32term.c (w32fullscreen_hook): New function.
1384 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1386 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1388 * fileio.c (Finsert_file_contents): Doc fix.
1390 * w32proc.c (new_child, delete_child, find_child_pid): For a
1391 subprocess, consider its slot being in use as long as its process
1392 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1393 slot when a new process is started immediately after killing
1394 another one, without waiting enough time for the first process to
1395 be reaped and resources allocated for it be orderly freed.
1397 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1399 2012-12-21 Chong Yidong <cyd@gnu.org>
1401 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1403 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1405 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1407 * w32.c (get_name_and_id): Always pass NULL as the first argument
1408 of lookup_account_sid. Avoids crashes with UNC file names that
1409 refer to DFS domains, not to specific machine names. (Bug#12621)
1410 Remove now unused argument FNAME; all callers changed.
1411 (get_file_owner_and_group): Remove now unused argument FNAME; all
1414 2012-12-21 Chong Yidong <cyd@gnu.org>
1416 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1417 error for invalid chars, don't check for a nil return value.

1460 * w32.c (acl_get_file, acl_set_file): Run the file name through

1477 * window.c (select_window_1): New func, extracted from select_window.
1478 (select_window): Use it.

1505 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1507 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1508 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1509 for some of that bug's symptoms can now cause Emacs to abort.
1510 Remove the workaround.
1511 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1512 The bug that caused SIGCHLD to get lost has been fixed, and the
1513 workaround for it can now cause Emacs to abort.
1515 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1517 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1560 asynchronous subprocess, record the name of the input file name,
1562 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1563 delete the file, record it as pending deletion when the subprocess
1566 2012-12-14 Eli Zaretskii <eliz@gnu.org>

1586 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1588 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1589 try to get accurate owner and group information from NT file
1590 security APIs. This is to make most callers of 'stat' and
1591 'lstat', which don't need that information, much faster.
1593 * dired.c (Ffile_attributes) [WINDOWSNT]:
1594 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1595 owner and group information from 'lstat'.
1597 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1599 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1600 as that confuses set-auto-coding, so insist on the head-read

1629 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1631 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1632 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1633 Remove unnecessary S_ISLNK test, as (contra the comments) this
1634 function can't copy symlinks. Improve quality of error message
1635 when attempting to copy files that are neither regular files nor

1654 * inotify.c (inotify_callback): Generate an Emacs event for every
1655 incoming inotify event.
1657 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1659 * xdisp.c (handle_face_prop): Fix logic of computing
1660 it->start_of_box_run_p.
1661 (append_space_for_newline): If the glyph row is R2L, reset the
1662 iterator's end_of_box_run_p flag before prepending the space glyph.
1663 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1664 iterator's start_of_box_run_p flag before prepending the stretch.

1667 left_box_line_p and right_box_line_p flags of the glyph for R2L
1668 glyph rows. (Bug#13011)

1894 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1896 * w32.c (unsetenv, sys_putenv): New functions.
1898 2012-12-08 Chong Yidong <cyd@gnu.org>
1900 * editfns.c (Finsert_char): Make the error message more
1901 informative (Bug#12992).
1903 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1905 Simplify get_lim_data.
1906 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1907 Remove USG and vlimit methods; no longer used these days.
1908 Add #error catchall just in case.
1910 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1911 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1912 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1913 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1914 (deleted_pid_list, Fdelete_process, create_process)
1915 (record_child_status_change, handle_child_signal, deliver_child_signal)
1916 (init_process_emacs, syms_of_process):
1917 Assume SIGCHLD is defined.
1918 (parse_signal): Remove. All uses removed.
1919 (abbr_to_signal): New static function.
1920 (Fsignal_process): Use it to convert signal names to ints.
1921 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1922 kill (getpgrp (), ...).
1923 (emacs_sigaction_init): Assume SIGCHLD is defined.
1924 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1925 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1926 * syssignal.h (EMACS_KILLPG): Remove.
1927 All uses replaced by 'kill' with a negative pid.
1928 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1929 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1931 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1933 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1934 This will cause a production Emacs to dump core instead of
1937 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1939 * frame.c (make_frame): Do not set window's buffer to t.
1940 * window.c (Fsplit_window_internal): Likewise. Previously it was
1941 used to indicate that the window is being set up. Now we use
1942 set_window_buffer for all new windows, so the condition in ...
1943 (Fset_window_buffer): ... is always true and can be removed.
1945 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1947 Convenient macro to check whether the buffer is hidden.
1948 * buffer.h (BUFFER_HIDDEN_P): New macro.
1949 * frame.c (make_frame): Use it. Adjust comment.
1950 * buffer.c (candidate_buffer): New function.
1951 (Fother_buffer, other_buffer_safely): Use it.
1953 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1955 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1956 if the child process is still running. Instead, exit the wait
1957 loop and return zero. (Bug#13086)
1959 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1961 * frame.h (x_char_width, x_char_height): Remove prototypes.
1962 * w32term.h (x_char_width, x_char_height): Likewise.
1963 * xfns.c (x_char_width, x_char_height): Remove.
1964 * w32fns.c (x_char_width, x_char_height): Likewise.

1972 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1974 Fix a recently-introduced delete-process race condition.
1975 * callproc.c, process.h (record_kill_process):
1976 New function, containing part of the old call_process_kill.
1977 (call_process_kill): Use it.
1978 This does not change call_process_kill's behavior.
1979 * process.c (Fdelete_process): Use record_kill_process to fix a
1980 race condition that could cause Emacs to lose track of a child.
1982 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1984 Avoid code duplication between prev_frame and next_frame.
1985 * frame.c (candidate_frame): New function. Add comment.
1986 (prev_frame, next_frame): Use it. Adjust comment.
1988 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1990 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1991 fails, signal an error instead of continuing with an empty
1993 Encode expanded temp file pattern before passing it to mkstemp or
1996 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1997 Encode the file name before passing it to dostounix_filename, in
1998 case it will downcase it (under w32-downcase-file-names).
2001 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2003 Minor call-process cleanups.
2004 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2005 at the same time as other platforms, to simplify analysis.
2006 No need for fd0_volatile since we have synch_process_fd.
2007 Avoid needless emacs_close; arg is always negative.
2009 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2011 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2014 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2016 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2017 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2018 and mouse_face_hidden members to a bitfields.
2019 * frame.h (struct frame): Remove set-but-not-used space_width member.
2020 (FRAME_SPACE_WIDTH): Remove.
2021 * nsterm.m, w32term.c, xterm.c: Adjust users.
2022 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2023 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2024 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2025 members to a bitfields.
2027 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2029 Don't let call-process be a zombie factory (Bug#12980).
2030 Fixing this bug required some cleanup of the signal-handling code.
2031 As a side effect, this change also fixes a longstanding rare race
2032 condition whereby Emacs could mistakenly kill unrelated processes,
2033 and it fixes a bug where a second C-g does not kill a recalcitrant
2034 synchronous process in GNU/Linux and similar platforms.
2035 The patch should also fix the last vestiges of Bug#9488,
2036 a bug which has mostly been fixed on the trunk by other changes.
2037 * callproc.c, process.h (synch_process_alive, synch_process_death)
2038 (synch_process_termsig, sync_process_retcode):
2039 Remove. All uses removed, to simplify analysis and so that
2040 less consing is done inside critical sections.
2041 * callproc.c (call_process_exited): Remove. All uses replaced
2042 with !synch_process_pid.
2043 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2044 These take the role of what used to be in unwind-protect arg.
2046 (block_child_signal, unblock_child_signal):
2047 New functions, to avoid races that could kill innocent-victim processes.
2048 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2049 (call_process_kill): Record killed processes as deleted, so that
2050 zombies do not clutter up the system. Do this inside a critical
2051 section, to avoid a race that would allow the clutter.
2052 (call_process_cleanup): Fix code so that the second C-g works again
2053 on common platforms such as GNU/Linux.
2054 (Fcall_process): Create the child process in a critical section,
2055 to fix a race condition. If creating an asynchronous process,
2056 record it as deleted so that zombies do not clutter up the system.
2057 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2058 light of these changes. Omit unnecessary call to emacs_close
2059 before failure, as the unwind-protect code does that.
2060 * callproc.c (call_process_cleanup):
2061 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2062 * process.c (record_deleted_pid): New function, containing
2063 code refactored out of Fdelete_process.
2064 (Fdelete_process): Use it.
2065 (process_status_retrieved): Remove. All callers changed to use
2066 child_status_change.
2067 (record_child_status_change): Remove, folding its contents into ...
2068 (handle_child_signal): ... this signal handler. Now, this
2069 function is purely a handler for SIGCHLD, and is not called after
2070 a synchronous waitpid returns; the synchronous code is moved to
2071 wait_for_termination. There is no need to worry about reaping
2072 more than one child now.
2073 * sysdep.c (get_child_status, child_status_changed): New functions.
2074 (wait_for_termination): Now takes int * status and bool
2075 interruptible arguments, too. Do not record child status change;
2076 that's now the caller's responsibility. All callers changed.
2077 Reimplement in terms of get_child_status.
2078 (wait_for_termination_1, interruptible_wait_for_termination):
2079 Remove. All callers changed to use wait_for_termination.
2080 * syswait.h: Include <stdbool.h>, for bool.
2081 (record_child_status_change, interruptible_wait_for_termination):
2083 (record_deleted_pid, child_status_changed): New decls.
2084 (wait_for_termination): Adjust to API changes noted above.
2086 * bytecode.c, lisp.h (Qbytecode): Remove.
2087 No longer needed after 2012-11-20 interactive-p changes.
2089 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2091 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2092 the scroll margin, move point outside the margin. (Bug#13055)
2094 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2096 * gtkutil.c (my_log_handler): New function.
2097 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2099 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2101 * lisp.h (modify_region): Rename to...
2102 (modify_region_1): ...new prototype.
2103 * textprop.c (modify_region): Now static. Adjust users.
2104 * insdel.c (modify_region): Rename to...
2105 (modify_region_1): ...new function to work with current buffer.
2106 Adjust comment and users. Use true and false for booleans.
2108 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2110 * alloc.c (free_save_value): New function.
2111 (safe_alloca_unwind): Use it.
2112 * lisp.h (free_save_value): New prototype.
2113 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2115 (save_excursion_restore): Adjust to match saved data structure.
2116 Use free_save_value to offload some work from GC. Drop obsolete
2119 2012-12-03 Chong Yidong <cyd@gnu.org>
2121 * fileio.c (Vauto_save_list_file_name): Doc fix.
2123 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2125 * w32fns.c: Remove prototype of atof.
2126 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2128 (file_dialog_callback): Make it UINT_PTR.
2130 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2133 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2134 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2137 2012-12-03 Glenn Morris <rgm@gnu.org>
2139 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2141 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2143 Fix xpalloc confusion after memory is exhausted.
2144 * alloc.c (xpalloc): Comment fix.
2145 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2146 and signals an error, do not clear charset_table_size, as
2147 charset_table is still valid.
2148 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2150 Use execve to avoid need to munge environ (Bug#13054).
2151 * callproc.c (Fcall_process):
2152 * process.c (create_process):
2153 Don't save and restore environ; no longer needed.
2154 * callproc.c (child_setup):
2155 Use execve, not execvp, to preserve environ.
2157 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2159 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2161 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2163 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2164 display for sliced images (Bug#10500).
2166 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2168 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2170 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2171 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2173 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2175 * xdisp.c (window_outdated): Remove eassert since it hits
2176 some suspicious corner cases (see Bug#13007 and Bug#13012).
2177 (mode_line_update_needed): New function.
2178 (redisplay_internal, redisplay_window): Use it.
2179 (ensure_selected_frame): New function.
2180 (redisplay_internal, unwind_redisplay): Use it.
2181 (redisplay_internal): Move comment about buffer_shared...
2182 (buffer_shared_and_changed): ...near to its real use.
2184 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2186 * callproc.c (Fcall_process): Don't misreport vfork failure.
2188 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2190 * callproc.c (Fcall_process): Fix vfork portability problems.
2191 Do not assume that fd[0], count, filefd, and save_environ survive
2192 vfork. Fix bug whereby wrong errno value could be reported for
2193 pipe failure. Some minor cleanups, too, as follows. Move buf and
2194 bufsize to the context where they're needed. Change new_argv to
2195 be of type char **, as this is more convenient and avoids casts.
2196 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2197 Now local constants, not macros.
2199 2012-11-18 Kenichi Handa <handa@gnu.org>
2201 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2202 for the variable "f".
2204 2012-11-13 Kenichi Handa <handa@gnu.org>
2206 * font.c (font_unparse_xlfd): Exclude special characters from the
2207 generating XLFD name.

2244 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2245 were always defined.
2247 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2249 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2250 between bpos_covered and bpos_max. This fixes cursor display when
2251 several display strings follow each other.
2253 * .gdbinit (pgx): If the glyph's object is a string, display the
2254 pointer to string data, rather than the value of the string object
2255 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2257 * indent.c (Fvertical_motion): If the starting position is covered
2258 by a display string, return to one position before that, to avoid
2259 overshooting it inside move_it_to. (Bug#12930)
2261 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2263 * frame.h (struct frame): Remove display_preempted member

2270 (struct w32_output): Use bitfields for explicit_parent,
2271 asked_for_visible and menubar_active members.
2272 Drop unused pending_menu_activation member.
2273 * xterm.h (struct x_output): Drop outdated #if 0 code.
2274 Use bitfields for explicit_parent, asked_for_visible,
2275 has_been_visible and net_wm_state_hidden_seen members.

2279 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2280 of a literal "/". (Bug#12955)
2281 (gl-stamp): Invoke fc.exe directly, not through cmd.
2283 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

2286 * dired.c: Assume HAVE_DIRENT_H.
2287 (NAMLEN): Remove, replacing with ...
2288 (dirent_namelen): New function. All uses changed. Use the GNU macro
2289 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2290 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2291 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2292 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2294 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2295 * ndir.h: Rename to ../nt/inc/dirent.h.
2296 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2297 Do not include <dirent.h>; no longer needed.
2298 * w32.c: Include <dirent.h> rather than "ndir.h".
2300 2012-11-23 Chong Yidong <cyd@gnu.org>
2302 * xftfont.c (xftfont_open): Remove duplicate assignment.
2304 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2306 * alloc.c (Fgarbage_collect): Unblock input after clearing
2307 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2308 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2309 * msdos.c (IT_frame_up_to_date): Use it here...
2310 * w32term.c (w32_frame_up_to_date): ...here...
2311 * xterm.c (XTframe_up_to_date): ...and here...
2312 * nsterm.m (ns_frame_up_to_date): ...but not here.
2313 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2315 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2316 Do not check whether GC is in progress.
2318 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2320 * xdisp.c (window_buffer_changed): New function.
2321 (update_menu_bar, update_tool_bar): Use it to
2322 simplify large 'if' statements.
2323 (redisplay_internal): Generalize commonly used
2324 'tail' and 'frame' local variables.
2326 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2328 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2329 with Windows system header.
2331 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2333 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

2350 * emacs.c (main): Set the G_SLICE environment variable for all
2351 Cygwin builds, not just GTK builds. See
2352 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2354 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2356 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2357 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2358 Define for the MSVC compiler.
2360 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2362 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2363 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2364 dostounix_filename. Prevents crashes down the road, because
2365 dostounix_filename assumes it gets a unibyte string.
2366 Reported by Michel de Ruiter <michel@sentient.nl>, see
2367 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2369 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2371 Conflate Qnil and Qunbound for `symbol-function'.

2373 * lread.c (init_obarray): Set `function' fields to Qnil.
2374 * eval.c (Fcommandp): Ignore Qunbound.
2375 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2376 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2377 Test NILP rather than Qunbound.
2378 (Ffmakunbound): Set to Qnil.
2379 (Fsymbol_function): Never signal an error.
2380 (Finteractive_form): Ignore Qunbound.
2382 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2384 * eval.c (interactive_p): Remove no-longer-used decl.
2386 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2388 * xdisp.c (buffer_shared): Adjust comment.
2389 (buffer_shared_and_changed): New function.
2390 (prepare_menu_bars, redisplay_internal): Use it to
2391 decide whether all windows or frames should be updated.
2392 (window_outdated): New function.
2393 (text_outside_line_unchanged_p, redisplay_window): Use it.
2394 (redisplay_internal): Likewise. Fix indentation.
2396 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2398 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2399 (syms_of_eval): Remove corresponding defsubr.
2400 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2402 2012-11-19 Daniel Colascione <dancol@dancol.org>
2404 * w32fns.c (Fx_file_dialog):
2405 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2406 cygwin_convert_file_name*.
2408 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2409 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2411 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2413 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2415 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2417 * w32select.c: Include w32common.h before w32term.h, so that
2418 windows.h gets included before w32term.h uses some of its
2419 features, see below.
2421 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2423 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2425 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2427 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2429 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2430 (ns_select): Return at once if events are held (Bug#12834).
2432 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2434 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2435 Needed following 2012-10-20 change. (Bug#12902)
2437 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2439 * w32proc.c (waitpid): Remove unused label get_result.
2441 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2443 * makefile.w32-in (SYSWAIT_H): New macro.
2444 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2445 ($(BLD)/sysdep.$(O)): Update dependencies.
2447 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2449 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2450 * callproc.c (relocate_fd): Assume F_DUPFD.
2451 * emacs.c, term.c (O_RDWR): Remove.
2452 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2453 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2454 * nsterm.m: Assume <fcntl.h> exists.
2455 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2456 (create_pty, Fmake_network_process, server_accept_connection)
2457 (wait_reading_process_output, init_process_emacs):
2459 (wait_reading_process_output): Put in a special case for WINDOWSNT
2460 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2461 It's not clear this is needed, but it's a more-conservative change.
2462 (create_process): Assume FD_CLOEXEC.
2463 (create_process, create_pty): Assume O_NOCTTY.
2464 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2465 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2466 Omit if not DOS_NT, since F_GETFL is not defined there.
2467 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2468 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2470 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2471 lack it, since gnulib guarantees this.
2472 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2474 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2476 * w32.c (faccessat): Pretend that directories have the execute bit
2477 set. Emacs expects that, e.g., in files.el:cd-absolute.
2479 * w32proc.c (create_child): Don't clip the PID of the child
2480 process to fit into an Emacs integer, as this is no longer a
2482 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2483 reaping only the process specified by PID argument, if that is
2484 positive. Use PID instead of dead_child to know which process to
2485 reap. Wait for the child to die only if WNOHANG is not in
2487 (sys_select): Don't set dead_child.
2489 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2490 as it is no longer needed.
2492 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2494 (record_child_status_change): Remove the setting of
2495 record_at_most_one_child for the !WNOHANG case.
2497 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2499 Fix problems in ns port found by static checking.
2500 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2501 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2502 not to process group.
2503 (ns_select): Use emacs_write, not write, as that's more robust
2504 in the presence of signals.
2505 (fd_handler:): Check for read errors.
2507 2012-11-16 Glenn Morris <rgm@gnu.org>
2509 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2511 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2513 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2515 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2517 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2518 use the same value of thread handle.
2519 (start_timer_thread): If the timer thread exited (due to error),
2520 clean up by closing the two handles it used. Duplicate the caller
2521 thread's handle here, so it gets duplicated only once, when
2522 launching the timer thread. Set priority of the timer thread, not
2524 (getitimer): Don't duplicate the caller thread's handle here.
2527 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2529 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2532 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2534 Remove no-longer-used pty_max_bytes variable.
2535 * process.c (pty_max_bytes): Remove; unused.
2536 (send_process): Do not set it.
2538 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2540 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2541 Update dependencies.
2543 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2545 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2546 This follows up on the 2012-09-29 patch that removed indirection
2547 for the 'function' field. Reported by Sergey Vinokurov in
2548 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2550 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2552 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2553 different name, as the MS runtime does not have such a function,
2554 and probably never will.) All callers changed. Ignore DIRFD
2555 value if PATH is an absolute file name, to match Posix spec
2556 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2559 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2561 * xdisp.c (echo_area_display, redisplay_internal):
2562 Omit redundant check whether frame_garbaged is set.
2564 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2566 Use faccessat, not access, when checking file permissions (Bug#12632).
2567 This fixes a bug that has been present in Emacs since its creation.
2568 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2569 which must set some sort of record. (Torek's bug report was against
2570 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2571 same common flaw.) See Torek's Usenet posting
2572 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2573 Posted: Fri Apr 8 14:18:56 1983.
2574 * Makefile.in (LIB_EACCESS): New macro.
2576 * callproc.c (init_callproc):
2577 * charset.c (init_charset):
2578 * fileio.c (check_existing, check_executable, check_writable)
2580 * lread.c (openp, load_path_check):
2581 * process.c (allocate_pty):
2583 Use effective UID when checking permissions, not real UID.
2584 * callproc.c (init_callproc):
2585 * charset.c (init_charset):
2586 * lread.c (load_path_check, init_lread):
2587 Test whether directories are accessible, not merely whether they exist.
2588 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2589 * fileio.c (check_existing, check_executable, check_writable)
2591 Use symbolic names instead of integers for the flags, as they're
2593 (check_writable): New arg AMODE. All uses changed.
2594 Set errno on failure.
2595 (Ffile_readable_p): Use faccessat, not stat + open + close.
2596 (Ffile_writable_p): No need to call check_existing + check_writable.
2597 Just call check_writable and then look at errno. This saves a syscall.
2598 dir should never be nil; replace an unnecessary runtime check
2599 with an eassert. When checking the parent directory of a nonexistent
2600 file, check that the directory is searchable as well as writable, as
2601 we can't create files in unsearchable directories.
2602 (file_directory_p): New function, which uses 'stat' on most platforms
2603 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2604 (Ffile_directory_p, Fset_file_times): Use it.
2605 (file_accessible_directory_p): New function, which uses a single
2606 syscall for efficiency.
2607 (Ffile_accessible_directory_p): Use it.
2608 * xrdb.c (file_p): Use file_directory_p.
2609 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2610 * lread.c (openp): When opening a file, use fstat rather than
2611 stat, as that avoids a permissions race. When not opening a file,
2612 use file_directory_p rather than stat.
2613 (dir_warning): First arg is now a usage string, not a format.
2614 Use errno. All uses changed.
2615 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2616 that merely introduced a race.
2617 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2618 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2619 and similarly for the other O_* flags.
2620 * w32.c (sys_faccessat): Rename from sys_access and switch to
2621 faccessat's API. All uses changed.
2622 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2623 (magic_db): Rename from magic_file_p.
2624 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2625 char *, so that we don't have to test for file existence
2626 separately from opening the file for reading. This removes a race
2627 fixes a permission-checking problem, and simplifies the code.
2629 (file_p): Remove; no longer needed.
2631 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2633 Omit glyphs initialization at startup.
2634 * dispnew.c (glyphs_initialized_initially_p): Remove.
2635 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2636 (Fredraw_frame): Move actual code from here...
2637 (redraw_frame): ...to here. Add eassert. Adjust comment.
2638 (Fredraw_display): Use redraw_frame.
2639 * xdisp.c (clear_garbaged_frames): Likewise.
2641 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2643 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2644 passed to pint2str and pint2hrstr to be at most the size of the
2645 frame's decode_mode_spec_buffer. This avoids crashes with very
2646 large values of FIELD_WIDTH argument to decode_mode_spec.
2649 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2651 Fix a race with verify-visited-file-modtime (Bug#12863).
2652 Since at least 1991 Emacs has ignored an mtime difference of no
2653 more than one second, but my guess is that this was to work around
2654 file system bugs that were fixed long ago. Since the race is
2655 causing problems now, let's remove that code.
2656 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2657 whose time stamp is off by no more than a second. Insist that the
2658 file time stamps match exactly.
2660 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2662 * frame.h (struct frame): Convert external_tool_bar member to
2663 1-bit unsigned bitfield.
2664 * termhooks.h (struct terminal): Remove mouse_moved member since
2665 all users are long dead. Adjust comment on mouse_position_hook.
2667 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2669 Simplify by using FOR_EACH_FRAME here and there.
2670 * frame.c (next_frame, prev_frame, other_visible_frames)
2671 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2672 * w32term.c (x_window_to_scroll_bar): Likewise.
2673 * window.c (window_list): Likewise.
2674 * xdisp.c (x_consider_frame_title): Likewise.
2675 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2676 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2677 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2678 * xmenu.c (menubar_id_to_frame): Likewise.
2679 * xselect.c (frame_for_x_selection): Likewise.
2680 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2681 (x_window_to_menu_bar): Likewise.
2682 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2684 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2686 * data.c (Qdefalias_fset_function): Now static.
2688 Another tweak to vectorlike_header change.
2689 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2690 Remove, and replace all uses with ...
2691 (next_in_free_list, set_next_in_free_list):
2692 New functions, which respect C's aliasing rules better.
2694 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2696 * window.c (list4i): Rename from 'quad'. All uses changed.
2697 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2699 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2701 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2702 warning about mixing declarations and code in ISO C90.
2704 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2706 * window.c (Fsplit_window_internal): Set combination limit of
2707 new parent window to t iff Vwindow_combination_limit is t;
2708 fixing a regression introduced with the change from 2012-09-22.
2709 (Fset_window_combination_limit): Fix doc-string.
2711 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2713 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2714 amount when the scroll margins are too large. When scrolling
2715 backwards in the buffer, give up if cannot reach point or the
2716 scroll margin within a reasonable number of screen lines.
2717 Fixes point position in window under scroll-up/down-aggressively when
2718 point is positioned many lines beyond the window top/bottom.
2721 * ralloc.c (relinquish): If real_morecore fails to return memory
2722 to the system, don't crash; instead, leave the last heap
2723 unchanged and return. (Bug#12774)
2725 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2727 * lisp.h (AUTOLOADP): New macro.
2728 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2729 * data.c (Ffset): Remove special ad-advice-info handling.
2730 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2732 (Finteractive_form): Simplify.
2733 (Fquo): Don't insist on having at least 2 arguments.
2734 (Qdefalias_fset_function): New var.
2736 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2738 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2740 * nsfont.m (Qcondensed, Qexpanded): New variables.
2741 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2742 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2744 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2746 Fix recently introduced crash on MS-Windows (Bug#12839).
2747 * w32term.h (struct scroll_bar): Use convenient header.
2748 (SCROLL_BAR_VEC_SIZE): Remove.
2749 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2751 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2753 Tweak last vectorlike_header change.
2754 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2755 vectorlike object on the free list. This is introduced to avoid
2756 some (but not all) pointer casting and aliasing problems, see
2757 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2758 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2760 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2762 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2764 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2765 been removed, so remove them here also.
2767 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2769 * doc.c (Fdocumentation): Handle new property
2770 dynamic-docstring-function to replace the old ad-advice-info.
2772 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2774 * fns.c (Qeql, hashtest_eq): Now static.
2776 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2778 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2779 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2780 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2781 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2783 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2785 Use same hash function for hashfn_profiler as for hash_string etc.
2786 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2787 * lisp.h (sxhash_combine): New inline function, with the contents
2788 of the old SXHASH_COMBINE.
2789 * profiler.c (hashfn_profiler): Use it, instead of having a
2790 special hash function containing a comparison that always yields 1.
2792 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2794 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2795 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2796 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2799 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2801 * image.c (xpm_make_color_table_h): Fix compiler error because
2802 make_hash_table changed.
2804 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2806 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2808 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2810 Use ad-hoc comparison function for the profiler's hash-tables.
2811 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2812 (make_log): Use them.
2813 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2814 call Fequal any more.
2815 (Ffunction_equal): New function.
2816 (cmpfn_profiler, hashfn_profiler): New functions.
2817 (syms_of_profiler): Initialize them.

2823 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2824 (hash_lookup, hash_remove_from_table): Move assertion checking of
2825 hashfn result here. Check hash-equality before calling cmpfn.
2826 (Fmake_hash_table): Adjust call to make_hash_table.
2827 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2828 (syms_of_fns): Initialize them.

2835 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2837 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2838 value of w32-scroll-lock-modifier is neither nil nor one of the
2839 known key modifiers. (Bug#12806)
2841 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2843 Shrink struct vectorlike_header to the only size field.
2844 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2846 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2847 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2848 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2849 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2850 information from the vector header. Adjust comment.

2862 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2863 (Fmake_bool_vector): Likewise.
2864 (struct large_vector): New type to represent allocation unit for
2865 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2866 (large_vectors): Change type to struct large_vector.
2867 (allocate_vector_from_block): Simplify.
2868 (PSEUDOVECTOR_NBYTES): Replace with...
2869 (vector_nbytes): ...new function. Adjust users.
2870 (sweep_vectors): Adjust processing of large vectors.
2871 (allocate_vectorlike): Likewise.
2872 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2873 Add easserts. Adjust XSETPVECTYPESIZE usage.
2874 (allocate_buffer): Use BUFFER_PVEC_INIT.
2875 (live_vector_p): Adjust to match large vector.
2876 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2877 * buffer.h (struct buffer): Add next member.
2878 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2880 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2886 (xvecsize): New command.
2888 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2890 * keyboard.c (event_to_kboard): Do not dereference
2891 frame_or_window field of SELECTION_REQUEST_EVENT
2892 and SELECTION_CLEAR_EVENT events (Bug#12814).
2893 * xterm.h (struct selection_input_event): Adjust comment.
2895 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2897 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2898 such as Scroll Lock, if the respective keys are treated as
2899 function keys, not as modifiers. This avoids destroying non-ASCII
2900 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2902 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2904 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2906 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2908 Restore some duplicate definitions (Bug#12814).
2909 This undoes part of the 2012-11-03 changes. Some people build
2910 with plain -g rather than with -g3, and they need the duplicate
2911 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2912 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2913 Define as macros, as well as as enums or as constants.
2915 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2917 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2918 to keypad keys (Bug#12816).
2920 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2922 Minor adjustments of recently-changed frame functions.
2923 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2924 known to be a frame (we're in the FRAMEP branch).
2925 * lisp.h (Qframep): Remove decl. frame.h declares this.
2926 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2927 since they're meant for Lisp fixnum values.
2929 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2931 * window.c (Fwindow_combination_limit): Revert to the only
2932 required argument and adjust docstring as suggested in
2933 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2934 by Martin Rudalics <rudalics@gmx.at>.
2936 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2938 Widely used frame validity and checking functions.
2939 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2940 * frame.c (decode_live_frame, decode_any_frame): New functions.
2941 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2942 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2943 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2944 (Fframe_pointer_visible_p): Use decode_any_frame.
2945 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2946 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2947 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2948 (Fframe_focus): Likewise. Allow zero number of arguments.
2950 (frame_buffer_list, frame_buffer_predicate): Remove.
2951 * lisp.h (frame_buffer_predicate): Remove prototype.
2952 * buffer.c (Fother_buffer): Use decode_any_frame.
2953 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2954 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2955 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2956 (Fclose_font, Ffont_info): Use decode_live_frame.
2957 * fontset.c (check_fontset_name): Likewise.
2958 * terminal.c (Fframe_terminal): Likewise.
2959 * w32fns.c (check_x_frame): Likewise.
2960 * window.c (Fminibuffer_window, Fwindow_at)
2961 (Fcurrent_window_configuration): Likewise.
2962 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2963 Likewise. Allow zero number of arguments. Adjust docstring.
2964 * dispnew.c (Fredraw_frame): Likewise.
2965 * xfaces.c (frame_or_selected_frame): Remove.
2966 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2967 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2968 (Fframe_face_alist): Use decode_live_frame.
2969 * xfns.c (check_x_frame): Likewise.
2971 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2973 * window.c (quad): New function.
2974 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2975 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2976 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2977 (Fwindow_line_height): Use it.
2978 (Fwindow_fringes): Use list3.
2979 (Fwindow_scroll_bars): Use list4.
2980 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2981 (Fwindow_combination_limit): Allow zero number of arguments.
2983 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2985 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2987 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2988 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2989 file descriptor 2 for standard error. (Bug#12805)
2991 2012-11-05 Chong Yidong <cyd@gnu.org>
2993 * process.c (wait_reading_process_output): Revert previous change.
2995 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2997 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2998 This removes code that has been obsolete since around 1990.
2999 * callproc.c (Fcall_process):
3001 * process.c (create_process):
3002 * term.c (dissociate_if_controlling_tty):
3003 Assume setsid exists.
3004 * callproc.c (child_setup): Assume setpgid exists and behaves as
3005 per POSIX.1-1988 or later.
3006 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3007 * emacs.c (shut_down_emacs):
3008 * sysdep.c (sys_suspend, init_foreground_group):
3009 Assume getpgrp behaves as per POSIX.1-1998 or later.
3010 * msdos.c (setpgrp): Remove.
3011 (tcgetpgrp, setpgid, setsid): New functions.
3012 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3013 * term.c (no_controlling_tty): Remove; unused.
3014 * w32proc.c (setpgrp): Remove.
3015 (setsid, tcgetpgrp): New functions.
3017 Simplify by assuming __fpending.
3018 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3019 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3020 Do not assume that __fpending's result fits in int.
3022 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3024 Remove EMACS_OUTQSIZE+sleep hack.
3025 * dispnew.c (update_frame_1): Remove hack for terminals slower
3026 than 2400 bps, which throttled Emacs by having it sleep.
3027 This code hasn't worked since at least 2007, when the multi-tty stuff
3028 was added, and anyway those old terminals are long dead.
3029 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3030 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3032 Fix data-loss with --version (Bug#9574).
3033 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3034 as we can't assume that emacs_strerror is initialized, and strerror
3035 is good enough here.
3036 (main): Invoke atexit earlier, to catch earlier instances of
3037 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3039 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3041 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3042 (keyDown): Remap keypad keys to X11 virtual key codes.
3044 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3046 Fix data-loss with --batch (Bug#9574).
3047 * emacs.c: Include <close-stream.h>.
3048 (close_output_streams): New function.
3049 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3050 and handles errors appropriately.
3051 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3054 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3055 The symptom is a diagnostic "GLib-WARNING **: In call to
3056 g_spawn_sync(), exit status of a child process was requested but
3057 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3058 waitpid(), so exit status can't be returned." The diagnostic
3059 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3060 The real bug is a race condition between Emacs and glib: Emacs
3061 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3062 so that glib can't find it. Work around the bug by invoking
3063 waitpid only on subprocesses that Emacs itself creates.
3064 * process.c (create_process, record_child_status_change):
3065 Don't use special value -1 in pid field, as the caller now must
3066 know the pid rather than having the callee infer it.
3067 The inference was sometimes incorrect anyway, due to another race.
3068 (create_process): Set new 'alive' member if child is created.
3069 (process_status_retrieved): New function.
3070 (record_child_status_change): Use it.
3071 Accept negative 1st argument, which means to wait for the
3072 processes that Emacs already knows about. Move special-case code
3073 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3074 processes that have already been waited for, by testing and
3075 clearing new 'alive' member.
3076 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3077 now does this internally.
3078 (handle_child_signal): Let record_child_status_change do all
3079 the work, since we do not want to reap all exited child processes,
3080 only the child processes that Emacs itself created.
3081 * process.h (Lisp_Process): New boolean member 'alive'.
3083 Omit duplicate definitions no longer needed with gcc -g3.
3084 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3085 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3086 Define only as macros. There's no longer any need to also define
3087 these symbols as enums or as constants, since we now assume
3088 gcc -g3 when debugging.
3090 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3092 * lisp.mk: Adjust comments to the fact that term/internal is now
3093 loaded from loadup.el.
3095 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3096 (msdos_fatal_signal): New function.
3097 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3100 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3101 for GCC versions before 4.
3102 (emacs_raise): Define to call msdos_fatal_signal.
3104 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3105 iterator when starting in the middle of a display or overlay
3108 2012-11-03 Chong Yidong <cyd@gnu.org>
3110 * process.c (wait_reading_process_output): Clean up the last
3113 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3115 * process.c (wait_reading_process_output): Avoid a race condition
3116 with SIGIO delivery (Bug#11536).
3118 2012-11-03 Chong Yidong <cyd@gnu.org>
3120 * buffer.c (cursor_type): Untabify docstring.
3122 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3124 * frame.h (struct frame): Drop can_have_scroll_bars member
3125 which is meaningless for a long time. Adjust comments.
3126 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3127 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3129 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3131 * window.c (decode_next_window_args): Update window arg after
3132 calling decode_live_window and so fix crash reported at
3133 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3134 by Juanma Barranquero <lekktu@gmail.com>.
3135 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3136 * font.c (Ffont_at): Likewise.
3138 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3140 * widget.c (resize_cb): New function.
3141 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3142 (EmacsFrameResize): Check if all is up to date before changing frame
3145 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3147 Implement backtrace output for fatal errors on MS-Windows.
3148 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3149 (BACKTRACE_LIMIT_MAX): New macro.
3150 (w32_backtrace): New function.
3151 (emacs_abort): Use w32_backtrace when the user chooses not to
3152 attach a debugger. Update the text of the abort dialog.
3154 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3156 Window-related stuff cleanup here and there.
3157 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3158 Use decode_any_window.
3159 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3160 * xdisp.c (Fformat_mode_line): Likewise.
3161 * font.c (Ffont_at): Use decode_live_window.
3162 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3163 * window.c (decode_next_window_args): Likewise.
3164 (decode_any_window): Remove static.
3165 * window.h (decode_any_window): Add prototype.
3166 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3167 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3170 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3172 Remove pad from struct input_event.
3173 * termhooks.h (struct input_event): Remove padding field.
3175 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3176 member is never cons for a long time. Adjust comment.
3177 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3178 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3179 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3180 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3182 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3184 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3186 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3188 Fix crash when using Emacs as commit editor for git (Bug#12697).
3189 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3190 and it is configured in conf_post.h.
3191 (Fcall_process): Don't invoke both setsid and setpgid; the former
3192 is enough, if it exists.
3193 * callproc.c (Fcall_process, child_setup):
3194 * process.c (create_process): Use setpgid.
3195 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3197 * dispnew.c (init_display): Initialize the foreground group
3198 if we are running a tty display.
3199 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3200 * lisp.h (init_foreground_group): New decl.
3201 * sysdep.c (inherited_pgroup): New static var.
3202 (init_foreground_group, tcsetpgrp_without_stopping)
3203 (narrow_foreground_group, widen_foreground_group): New functions.
3204 (init_sys_modes): Narrow foreground group.
3205 (reset_sys_modes): Widen foreground group.
3207 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3209 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3211 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3213 * minibuf.c (read_minibuf): Restore current buffer since
3214 choose_minibuf_frame calling Fset_frame_selected_window may
3215 change it (Bug#12766).
3217 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3219 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3221 2012-10-30 Kenichi Handa <handa@gnu.org>
3223 * font.c (Ffont_at): If WINDOW is specified and it is not
3224 displaying the current buffer, signal an error.
3226 2012-10-29 Daniel Colascione <dancol@dancol.org>
3228 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3229 In preparation for fixing bug#12739, move these functions from
3232 * coding.h, coding.c: ... to here, and compile them only when
3233 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3234 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3236 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3238 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3239 (timer_loop, getitimer, setitimer): Use it instead of
3240 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3242 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3245 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3247 * nsterm.m (NO_APPDEFINED_DATA): New define.
3248 (last_appdefined_event_data): New variable
3249 (last_appdefined_event): Remove.
3250 (ns_select): Initialize t from last_appdefined_event_data instead
3251 of [last_appdefined_event data1].
3252 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3253 remove last_appdefined_event (Bug#12698).
3255 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3257 * frame.c (x_set_font): Catch internal error.
3259 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3261 Avoid overflow in w32 implementation of interval timers.
3262 When possible, for ITIMER_PROF count only times the main thread
3264 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3265 'volatile ULONGLONG' types. All the other data which was
3266 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3267 (GetThreadTimes_Proc): New typedef.
3268 (w32_get_timer_time): New function, returns a suitable time value
3270 (timer_loop): Enter critical section when accessing ULONGLONG
3271 values of the itimer_data struct, as these accesses are no longer
3272 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3273 Remove unused variable.
3274 (init_timers): Initialize s_pfn_Get_Thread_Times.
3275 (start_timer_thread): Don't assign itimer->caller_thread here.
3276 (getitimer): Assign itimer->caller_thread here.
3277 (setitimer): Always call getitimer to get the value of ticks_now.

3282 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3283 mouse movement events if the menu bar is active. This avoids
3284 producing a busy "hour-glass" cursor by Windows if the mouse
3285 pointer is positioned over a tooltip shown for some menu item.
3287 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3289 Don't assume process IDs fit in int.
3290 * emacs.c (shut_down_emacs) [!DOS_NT]:
3291 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3292 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3293 Use pid_t, not int, to store process IDs, as 'int'
3294 is not wide enough on a few platforms (e.g., AIX and IRIX).
3296 2012-10-23 Kenichi Handa <handa@gnu.org>
3298 The following change is to make face-font-rescale-alist work
3299 correctly for non-ASCII fonts.

3302 (font_open_for_lface): Handle Vface_font_rescale_alist.
3304 2012-10-23 Chong Yidong <cyd@gnu.org>
3306 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3308 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

3317 2012-10-21 Glenn Morris <rgm@gnu.org>
3319 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3321 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3323 Port to OpenBSD 5.1.
3324 * frame.c (Fmouse_position, Fmouse_pixel_position):
3325 * xdisp.c (produce_stretch_glyph):
3326 Declare local vars only when they're needed.
3327 This is clearer and avoids a warning on OpenBSD about unused vars.
3328 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3329 This is safer, and avoids OpenBSD warnings about unused vars.
3330 * keyboard.c (record_menu_key): Remove unnecessary decl.
3331 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3332 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3333 as our definition clashes with OpenBSD's.
3334 * xfaces.c (load_face_colors, check_lface_attrs)
3335 (get_lface_attributes_no_remap, get_lface_attributes)
3336 (lface_fully_specified_p, x_supports_face_attributes_p)
3337 (tty_supports_face_attributes_p, face_fontset, realize_face)
3338 (realize_x_face, realize_tty_face):
3339 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3340 merely Lisp_Object *. This is more informative and avoids
3341 a warning on OpenBSD about accessing beyond an object's size.
3343 2012-10-20 Chong Yidong <cyd@gnu.org>
3345 * lread.c (Fload): Doc fix (Bug#12592).

3349 * font.c (Ffont_at): Fix previous change.
3351 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3353 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3354 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

3371 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3372 (staticpro): If we run out of staticpro slots, die with an
3373 informative error instead of just calling emacs_abort.
3375 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3377 Fix two flaws reported by Dmitry Antipov.
3378 * window.c (Ftemp_output_buffer_show): Remove.

3634 (get_input_pending): Remove first argument, since it was always
3635 the same pointer-to-int (now pointer-to-boolean) &input_pending,

3637 input_pending. All callers changed.
3638 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3639 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3685 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3686 'is_tooltip_frame', to avoid confusion with its global namesake.
3688 2012-10-08 Daniel Colascione <dancol@dancol.org>
3690 * xdisp.c (start_hourglass): Call w32_note_current_window when
3691 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3692 build that caused Emacs to display the hourglass cursor forever.
3694 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3695 which is broken under remote desktop, calculate the number of
3696 colors available for a display based on the display's number of
3697 planes and number of bits per pixel per plane. (bug#10397).
3699 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3701 * nsfont.m (Vfonts_in_cache): New variable.

3716 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3718 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3719 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3720 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3721 (GLOBAL_SOURCES): Add cygw32.c.
3722 ($(BLD)/unexw32.$(O)):
3724 ($(BLD)/w32console.$(O)):
3725 ($(BLD)/w32fns.$(O)):
3726 ($(BLD)/w32heap.$(O)):
3727 ($(BLD)/w32menu.$(O)):
3728 ($(BLD)/w32proc.$(O)): Add w32common.h.
3730 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3732 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3734 2012-10-08 Daniel Colascione <dancol@dancol.org>
3736 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3737 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3738 accidental message numbering hole. Change other messages to
3741 * w32select.h (HAVE_W32SELECT): Remove.
3743 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3744 w32common.h instead of w32heap.h.
3746 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3747 (get_allocation_unit, get_processor_type, get_w32_major_version)
3748 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3749 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3750 (OS_NT, os_subtype, cache_system_info): Move declarations to
3753 * w32heap.c: Include w32common.h.
3754 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3755 (w32_minor_version, w32_build_number, w32_subtype):
3756 Remove duplicate definitions.
3758 * w32fns.c: Include w32common.h; include w32heap.h only in
3761 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3762 Use `report_file_error' instead of `error' in order to better
3763 inform users of what went wrong. Increase NTGUI_UNICODE file
3764 dialog box file name length to 32k, the maximum allowed by the NT
3767 * w32common.h: New file.
3768 (ROUND_UP, ROUND_DOWN, get_page_size)
3769 (get_allocation_unit, get_processor_type, get_w32_major_version)
3770 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3771 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3772 (OS_NT, os_subtype, cache_system_info): Move here.
3774 * unexw32.c, unexcw.c: Include w32common.h.
3776 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3777 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3778 to call syms_of_w32select.
3780 * cygw32.h: Remove obsolete EXFUN declarations.
3782 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3784 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3785 of w32inevt.o from SOME_MACHINE_OBJECTS.
3787 2012-10-08 Daniel Colascione <dancol@dancol.org>
3789 * image.c: Permanent fix for JPEG compilation issue --- limit
3790 jpeglib `boolean' redefinition to Cygwin builds.
3792 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3794 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3796 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3799 2012-10-08 Daniel Colascione <dancol@dancol.org>
3801 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3802 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3803 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3804 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3805 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3806 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3807 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3808 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3809 now a supported configuration.
3811 * Makefile.in: consolidate image variables into LIBIMAGE; add
3812 W32_OBJ and W32_LIBS. Compile new files.
3815 (_DebPrint) declare tracing facility for W32 debugging. We need
3816 to unify tracing later.
3818 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3819 unconditional use of W32 Unicode functions. Cygwin runs only on
3820 100% Unicode operating systems.
3822 * cygw32.c: New file. Define Cygwin-specific facilities.
3823 (Fcygwin_convert_path_to_windows)
3824 (Fcygwin_convert_path_from_windows): New user functions for
3825 accessing Cygwin path-munging routines.
3827 * cygw32.h: New file.
3828 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3829 UTF-16LE strings temporarily inside non-Lisp-visible string
3832 (w32_strerror): Just what it says on the tin.
3834 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3835 also run for Cygwin; both systems have the same problem with using
3836 GUI facilities in a forked child. Also call syms_of_cygw32,
3837 syms_of_w32select in correct places.
3839 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3840 needs fork-then-exec for daemon launching.
3842 * font.h: Include frame.h.
3844 * image.c: Use the image library cache machinery only when we're
3845 compiling for native WINDOWSNT; Cygwin can use shared libraries
3846 like any other Unixlike system.
3848 * keyboard.c: Clarify a comment regarding the input loop.
3850 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3851 functions directly instead of trying to detect at runtime that our
3852 host operating system supports them. We make this change for two
3853 reasons: Cygwin lacks support for the multibyte character
3854 conversion functions used by the legacy menu code, and Cygwin
3855 never needs to rely on non-Unicode APIs.
3857 * unexw32.c (hinst): Declare extern.
3859 * w32.c: Change header order;
3860 (w32_strerror): Move to w32fns.c because we need it for
3861 non-WINDOWSNT builds.
3863 * w32.h: Add #error macro to make sure we don't include w32.h for
3864 Cygwin builds. Remove w32select declarations.
3866 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3867 w32fns.c. w32console.c is WINDOWSNT-only.
3869 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3870 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3872 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3873 (w32_major_version, w32_minor_version, w32_build_number)
3874 (os_subtype, sound_type): Define here
3875 (w32_defined_color): Make color parameter const for consistency
3876 with other _defined_color functions.
3877 (w32_createwindow): Unconditionally call w32_init_class instead of
3878 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3879 through the code is complex and unnecessary because class
3880 registration is practically free.
3881 (w32_name_of_message): New EMACSDEBUG-only function.
3882 (Fset_message_beep): Move here
3883 (Fx_open_connection): Require that the display name for Windows be
3884 "w32" for consistency, emacsclient disambiguation, and maybe, one
3885 day, multi-window-system support.
3886 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3887 Cygwin files for W32 GUI facilities, since these clearly don't
3888 expect Cygwin names.
3889 (_DebPrint): Define.
3890 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3891 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3892 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3893 (w32_last_error): Remove.
3895 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3897 * w32heap.c (syspage_mask): Declare here.
3898 (cache_system_info): Remove.
3900 * w32inevt.c (faked_key): Define globally, not statically.
3901 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3902 (w32_console_toggle_lock_key): Move to w32fns.c.
3904 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3906 * w32proc.c (_DebPrint): Move to w32fns.c.
3907 * w32select.c: Include string.h, stdio.h for Cygwin.
3908 * w32select.h: New File.
3910 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3912 (w32_message_fd): New variable. Under Cygwin, holds the file
3913 descriptor the system used to tell us about pending thread
3916 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3917 that prevented compilation under non-WINDOWSNT systems.
3919 (w32_initialize): Open /dev/windows and assign it to
3920 w32_message_fd. Provide w32 feature.
3922 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3923 (WM_EMACS_INPUT_READY): add.
3924 (prepend_msg, w32_message_fd): Declare globally.
3927 (keyboard_handle): Use only when WINDOWSNT.
3928 (notify_msg_ready): New function. Posts a message to the main
3929 thread's message queue under CYGWIN, which wakes up the main
3930 thread from select(2) by making the /dev/windows file descriptor
3931 ready. Under WINDOWSNT, it sets an event the same way the old
3934 (post, prepend_msg): Actually call notify_msg_ready instead of
3935 setting the input event directly.
3937 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3939 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3940 but it still has blocs in it, don't return it to the system,
3941 instead of aborting. (Bug#12402)
3943 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3945 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3947 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3948 MAC_OS_X_VERSION_10_6.
3949 (syms_of_nsterm): Remove comment about Panther and above for
3951 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3952 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3953 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3955 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3956 MAC_OS_X_VERSION_10_4.
3958 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3959 MAC_OS_X_VERSION_10_2.
3961 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3963 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3964 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3966 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3967 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3968 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3969 Remove ns_in_resize check.
3970 (ns_clear_frame_area): Remove resize handle code.
3972 * nsfns.m (ns_in_resize): Remove.
3973 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3974 Remove ns_in_resize check.
3976 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3978 Improve sys_siglist detection.
3979 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3980 defined as a macro, as is done in Solaris.
3981 (sys_siglist_entries): New macro.
3982 (save_strsignal): Use it.
3983 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3984 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3986 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3988 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3989 fullscreen/Fullscreen.
3991 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3992 tobar_height is new.
3994 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3995 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3996 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3997 (windowDidResize:): Check for correct window if old style fullscreen.
3998 Capitalize word in comment. Remove incorrect comment.
3999 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4000 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4001 error in drawing background.
4002 (toggleFullScreen:): Remove comment. Rearrange calls.
4003 Set toolbar values to zero, save old height in tobar_height.
4004 Restore tool bar height when leaving fullscreen.
4005 (canBecomeMainWindow): New function.
4007 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4009 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4011 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4013 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4015 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4016 that time stamps of directories could also be changed.
4017 Don't request the too broad GENERIC_WRITE, only the more restrictive
4018 FILE_WRITE_ATTRIBUTES access rights.
4020 * fileio.c (Fset_file_times): Special-case ignoring errors for
4021 directories only on MSDOS, not on MS-Windows.
4023 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4025 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4027 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4029 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4030 see whether CreateFile failed.
4032 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4034 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4035 to avoid similar races.
4036 * keyboard.c (pending_signals): Now bool, not int.
4038 Port timers to OpenBSD, plus check for timer failures.
4039 OpenBSD problem reported by Han Boetes.
4040 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4042 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4043 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4044 like OpenBSD, which has timer_settime but does not declare it.
4045 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4046 whether to use itimerspec-related primitives. All uses of
4047 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4049 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4051 * profiler.c (handle_profiler_signal): Fix a malloc race
4052 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4054 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4056 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4058 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4060 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4061 consistent with the change in return value of 'safe_strsignal'.
4063 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4065 Prefer plain 'static' to 'static inline' (Bug#12541).
4066 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4067 (bidi_set_sor_type, bidi_push_embedding_level)
4068 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4069 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4070 (bidi_cache_search, bidi_cache_ensure_space)
4071 (bidi_cache_iterator_state, bidi_cache_find)
4072 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4073 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4074 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4075 Now 'static', not 'static inline'.
4077 Count overruns when profiling; change units to ns.
4078 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4079 Give extra weight to samples after overruns, to attempt to count
4080 the time more accurately.
4081 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4082 the underlying primitives nominally do ns.
4083 (Fprofiler_cpu_start): Document the change. Mention that
4084 the sampling intervals are only approximate.
4086 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4088 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4090 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4091 case for the special 0 coding-system.
4093 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4094 (Fmake_overlay): Remove redundant tests.
4095 (fix_start_end_in_overlays): Remove redundant recentering.
4097 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4099 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4100 Update dependencies.
4102 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4104 Fix a malloc race condition involving strsignal.
4105 A signal can arrive in the middle of a malloc, and Emacs's signal
4106 handler can invoke strsignal, which can invoke malloc, which is
4107 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4108 Fix it by altering the signal handler so that it does not invoke
4110 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4111 * process.c (status_message): Use const pointer, in case strsignal
4112 is #defined to safe_strsignal.
4113 * sysdep.c (sys_siglist, init_signals): Always define and
4114 initialize a substitute sys_siglist if the system does not define
4115 one, even if HAVE_STRSIGNAL.
4116 (safe_strsignal): Rename from strsignal. Always define,
4117 using sys_siglist. Return a const pointer.
4118 * syssignal.h (safe_strsignal): New decl.
4119 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4121 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4123 * w32proc.c (timer_loop): Fix code that waits for timer
4124 expiration, to avoid high CPU usage.
4126 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4128 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4129 (sweep_weak_table): Remove redundant prototypes.
4131 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4133 * emacs.c: Move the inclusion of TERM_HEADER after including
4134 windows.h on WINDOWSNT. This avoids compilation problems with
4137 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4139 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4140 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4141 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4142 as the previous version used 'void *'.
4144 * ralloc.c (ROUNDUP): Fix last change.
4145 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4148 * w32proc.c <disable_itimers>: New static flag.
4149 (init_timers): Initialize it to zero, after creating the critical
4150 sections used by the timer threads.
4151 (term_timers): Set to 1 before deleting the critical sections.
4152 (getitimer, setitimer): If disable_itimers is non-zero, return an
4153 error indication without doing anything. Reported by Fabrice
4154 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4155 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4157 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4160 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4161 term_ntproc after all the other bookkeeping, to get timers working
4162 as long as possible.
4164 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4166 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4167 Suggested by Juri Linkov in
4168 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4170 Prefer plain 'static' to 'static inline' (Bug#12541).
4171 With static functions, modern compilers inline pretty well by
4172 themselves; advice from programmers often hurts as much as it helps.
4173 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4174 this change shrinks the text size of the Emacs executable by 1.1%
4175 without affecting CPU significantly in my benchmark.
4176 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4177 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
4178 (mark_maybe_object, mark_maybe_pointer, bounded_number):
4179 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
4180 (bset_auto_fill_function, bset_auto_save_file_format)

4474 for consistency with other handlers.
4475 (setup_cpu_timer): New function, with much of what used to be in

4548 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4549 Since this stuff is now private to charset.c, there's no need for
4550 a public macro and no need to inline by hand.

4627 consistency with a signature of a signal handler. All callers
4629 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4630 install term_ntproc as a signal handler for SIGABRT, as that
4631 should be done by the dumped Emacs.
4633 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4635 * w32select.c (term_w32select): Protect against repeated
4636 invocation by setting clipboard_owner to NULL after calling
4639 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4640 and term_ntproc to their modified signatures.
4642 * character.c (char_string, string_char): Remove calls to
4643 MAYBE_UNIFY_CHAR. See the discussion starting at
4644 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4647 2012-09-25 Chong Yidong <cyd@gnu.org>
4649 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4651 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4653 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4654 when encountering an unknown bytecode.
4656 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4658 image.c, indent.c: Use bool for booleans.
4659 * dispextern.h (struct image_type): Members valid_p, load, init
4660 now return bool, not int. All uses changed.
4661 * image.c: Omit unnecessary static decls.
4662 (x_create_bitmap_mask, x_build_heuristic_mask):
4663 Return void, not int, since callers don't care about the return value.

4696 * chartab.c (Fset_char_table_default): Obsolete function removed.
4698 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4700 Move pid_t related decls out of lisp.h.
4701 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4702 (interruptible_wait_for_termination):
4703 Move these decls from lisp.h to syswait.h, since they use pid_t.
4704 Needed on FreeBSD; see Herbert J. Skuhra in
4705 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4706 * callproc.c: Include syswait.h.

4724 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4725 * xfns.c (Fx_show_tip) [USE_GTK]:
4726 Use bool for boolean.
4727 * gtkutil.c (xg_update_frame_menubar):
4728 * xmenu.c (update_frame_menubar):
4729 Return void, not int, since caller ignores return value.
4730 * gtkutil.c (xg_change_toolbar_position):
4733 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4735 * makefile.w32-in (BLOCKINPUT_H): Remove.

4752 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4754 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4755 fatal_error_backtrace.
4757 * w32proc.c (sys_kill): Undo last change: don't do anything when
4758 invoked to deliver SIGABRT to our own process. This is now
4759 handled by emacs_raise.
4761 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4763 * w32term.c (w32_read_socket): Remove leftover reference to
4764 interrupt_input_pending.
4766 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4768 Do not use SA_NODEFER.
4769 Problem reported by Dani Moncayo in
4770 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4772 * sysdep.c (emacs_abort): Do not reset signal handler.
4773 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4774 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4775 wanted even on POSIXish hosts, and it doesn't work on Windows.
4777 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4779 * xterm.c (x_term_init): Call fixup_locale before and after calling
4780 gtk_init (Bug#12392).
4782 2012-09-23 Chong Yidong <cyd@gnu.org>
4784 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4785 Vdynamic_library_alist.
4787 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4788 (Fgnutls_available_p): Caller changed.
4790 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4791 (Flibxml_parse_xml_region): Likewise.
4793 * dispextern.h (struct image_type): Remove arg from init function.
4795 * image.c (Finit_image_library, lookup_image_type)
4796 (define_image_type): Remove now-unneeded second arg.
4797 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4798 (init_tiff_functions, init_gif_functions, init_svg_functions):
4799 Arglist and w32_delayed_load calling convention changed.
4800 (gs_type): Remove init_gs_functions; there is no such function.
4801 (valid_image_p, make_image): Fix caller to lookup_image_type.
4803 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4805 Simplify and avoid signal-handling races (Bug#12471).
4807 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4808 Avoid recursive loop if there's a fatal error in the function itself.
4809 * atimer.c (pending_atimers):
4810 * blockinput.h: Don't include "atimer.h"; no longer needed.
4811 (interrupt_input_pending): Remove. All uses removed.
4812 pending_signals now counts both atimers and ordinary interrupts.
4813 This is less racy than having three separate pending-signal flags.
4814 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4816 Rename from their upper-case counterparts BLOCK_INPUT,
4817 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4818 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4819 This makes it easier to access volatile variables more accurately.
4820 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4821 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4822 that's more reliable if the code is buggy and sets
4823 interrupt_input_blocked to a negative value. All uses changed.
4824 * atimer.c (deliver_alarm_signal):
4825 Remove. No need to deliver this to the parent; any thread can
4826 handle this signal now. All uses replaced by underlying handler.
4827 * atimer.c (turn_on_atimers):
4828 * dispnew.c (handle_window_change_signal):
4829 * emacs.c (handle_danger_signal):
4830 * keyboard.c (kbd_buffer_get_event):
4831 Don't reestablish signal handler; not needed with sigaction.
4832 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4834 Rework to avoid unnecessary accesses to volatile variables.
4835 (UNBLOCK_INPUT_TO): Now a function.
4836 (totally_unblock_input, unblock_input): New decls.
4837 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4838 (init_data): Remove. Necessary stuff now done in init_signal.
4839 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4840 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4841 (fatal_error_code): Remove; no longer needed.
4842 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4843 it doesn't always backtrace. All uses changed. No need to reset
4844 signal to default, since sigaction and/or die does that for us now.
4845 Use emacs_raise (FOO), not kill (getpid (), FOO).
4846 (main): Check more-accurately whether we're dumping.
4847 Move fatal-error setup to sysdep.c
4848 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4849 * gtkutil.c (xg_get_file_name, xg_get_font):
4850 Remove no-longer-needed signal-mask manipulation.
4851 * keyboard.c, process.c (POLL_FOR_INPUT):
4852 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4853 * keyboard.c (read_avail_input): Remove.
4854 All uses replaced by gobble_input.
4855 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4856 (kbd_buffer_store_event_hold, gobble_input):
4857 (record_asynch_buffer_change) [USABLE_SIGIO]:
4858 (store_user_signal_events):
4859 No need to mess with signal mask.
4860 (gobble_input): If blocking input and there are terminals, simply
4861 set pending_signals to 1 and return. All hooks changed to not
4862 worry about whether input is blocked.
4863 (process_pending_signals): Clear pending_signals before processing
4864 them, in case a signal comes in while we're processing.
4865 By convention callers now test pending_signals before calling us.
4866 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4867 New functions, to support changes to blockinput.h.
4868 (handle_input_available_signal): Now extern.
4869 (reinvoke_input_signal): Remove. All uses replaced by
4871 (quit_count): Now volatile, since a signal handler uses it.
4872 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4873 All callers changed. Block SIGINT only if not already blocked.
4874 Clear sigmask reliably, even if Fsignal returns, which it can.
4875 Omit unnecessary accesses to volatile var.
4876 (quit_throw_to_read_char): No need to restore sigmask.
4877 * keyboard.c (gobble_input, handle_user_signal):
4878 * process.c (wait_reading_process_output):
4879 Call signal-handling code rather than killing ourselves.
4880 * lisp.h: Include <float.h>, for...
4881 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4882 (pending_signals): Now volatile.
4883 (syms_of_data): Now const if IEEE floating point.
4884 (handle_input_available_signal) [USABLE_SIGIO]:
4885 (terminate_due_to_signal, record_child_status_change): New decls.
4886 * process.c (create_process): Avoid disaster if memory is exhausted
4887 while we're processing a vfork, by tightening the critical section
4889 (send_process_frame, process_sent_to, handle_pipe_signal)
4890 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4892 (send_process): No need for setjmp/longjmp any more, since the
4893 SIGPIPE stuff is now gone. Instead, report an error if errno
4895 (record_child_status_change): Now extern. PID and W are now args.
4896 Return void, not bool. All callers changed.
4897 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4898 Remove. All uses removed. This bug should be fixed now in a
4900 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4901 and record the child status change directly. This avoids the
4902 need to futz with the signal mask.
4903 (process_fatal_action): Move here from emacs.c.
4904 (emacs_sigaction_flags): New function, containing
4905 much of what used to be in emacs_sigaction_init.
4906 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4907 caught by emacs, to make races less likely.
4908 (deliver_process_signal): Rename from handle_on_main_thread.
4910 (BACKTRACE_LIMIT_MAX): Now at top level.
4911 (thread_backtrace_buffer, threadback_backtrace_pointers):
4913 (deliver_thread_signal, deliver_fatal_thread_signal):
4914 New functions, for more-accurate delivery of thread-specific signals.
4915 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4916 (deliver_arith_signal): Handle in this thread, not
4917 in the main thread, since it's triggered by this thread.
4918 (maybe_fatal_sig): New function.
4919 (init_signals): New arg DUMPING so that we can be more accurate
4920 about whether we're dumping. Caller changed.
4921 Treat thread-specific signals differently from process-general signals.
4922 Block all signals while handling fatal error; that's safer.
4923 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4925 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4926 Ignore SIGPIPE unless batch.
4927 (emacs_backtrace): Output backtrace for the appropriate thread,
4928 which is not necessarily the main thread.
4929 * syssignal.h: Include <stdbool.h>.
4930 (emacs_raise): New macro.
4931 * xterm.c (x_connection_signal): Remove; no longer needed
4932 now that we use sigaction.
4933 (x_connection_closed): No need to mess with sigmask now.
4934 (x_initialize): No need to reset SIGPIPE handler here, since
4935 init_signals does this for us now.
4937 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4939 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4940 background rect may be larger (Bug#12245).
4942 2012-09-23 Chong Yidong <cyd@gnu.org>
4944 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4946 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4948 * .gdbinit: Just stop at fatal_error_backtrace.
4949 See Stefan Monnier's request in
4950 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4951 Remove no-longer-used query of system type.
4953 2012-09-22 Chong Yidong <cyd@gnu.org>
4955 * search.c (Freplace_match): Doc fix (Bug#12325).
4957 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4959 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4960 (Fline_end_position): Doc fix.
4962 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4964 2012-09-22 Chong Yidong <cyd@gnu.org>
4966 * dispextern.h (struct image_type): Add new slot, storing a type
4967 initialization function.
4969 * image.c (define_image_type): Call the image initializer function
4970 if it is defined. Arguments and return value changed.
4971 (valid_image_p, make_image): Callers changed.
4972 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4973 (gif_type, imagemagick_type, svg_type, gs_type):
4974 Add initialization functions.
4975 (Finit_image_library): Call lookup_image_type.
4976 (CHECK_LIB_AVAILABLE): Macro deleted.
4977 (lookup_image_type): Call define_image_type here, rather than via
4978 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4979 (syms_of_image): Move define_image_type calls for xbm_type and
4980 pbm_type to lookup_image_type.
4982 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4984 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4985 'idle_timers' from here ...
4986 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4987 lists, to avoid infloops when the timer does something stupid,
4988 like reinvoke itself with the same or smaller time-out.
4991 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4993 * window.c (Fsplit_window_internal): Handle only Qt value of
4994 Vwindow_combination_limit separately.
4995 (Qtemp_buffer_resize): New symbol.
4996 (Vwindow_combination_limit): New default value.
4999 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5001 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5002 the new overlay string. (Bug#10159)
5004 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5006 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5007 or that fprintf is async-signal-safe. POSIX doesn't require
5010 2012-09-22 Chong Yidong <cyd@gnu.org>
5012 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5015 2012-09-22 Kenichi Handa <handa@gnu.org>
5017 * composite.c (composition_reseat_it): Handle the case that a
5018 grapheme cluster is not covered by a single font (Bug#12352).
5020 2012-09-21 Chong Yidong <cyd@gnu.org>
5022 * image.c (define_image_type): Avoid adding duplicate types to
5023 image_types (Bug#12463). Suggested by Jörg Walter.
5025 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5027 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5028 (print_load_command_name): Add case LC_DATA_IN_CODE.
5029 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5031 2012-09-21 Glenn Morris <rgm@gnu.org>
5033 * eval.c (Frun_hook_with_args_until_success)
5034 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5036 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5038 * fileio.c (Ffile_selinux_context): Only call freecon when
5039 lgetfilecon succeeded.
5040 (Fset_file_selinux_context): Likewise. (Bug#12444)
5042 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5044 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5045 reordering, locate the cursor by calling set_cursor_from_row; if
5046 that fails, clear the desired glyph matrix before returning a
5047 failure indication to the caller. Fixes leaving garbled display
5048 when fast scrolling with a down-key. (Bug#12403)
5049 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5050 scrolling through multibyte text.
5052 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5054 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5055 calling mark_vectorlike since that's the one that marks the window.
5056 (mark_discard_killed_buffers): Mark the final cdr.
5057 * window.h (struct window): Move prev/next_buffers to the
5058 non-standard fields.
5059 * window.c (make_window): Initialize prev/next_buffers manually.
5061 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5063 Omit unused arg EXPECTED from socket hooks.
5064 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5065 * nsterm.m (ns_term_init):
5066 * termhooks.h (struct terminal.read_socket_hook):
5067 * w32inevt.c (w32_console_read_socket):
5068 * w32term.c (w32_read_socket):
5069 * xterm.c (XTread_socket):
5070 Omit unused arg EXPECTED. All callers changed.
5071 (store_user_signal_events): Return void, not int, since callers no
5072 longer care about the return value. All uses changed.
5074 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5076 * w32gui.h (XParseGeometry): Do not declare.
5078 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5080 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5081 Ignore 'expected'. See Eli Zaretskii in
5082 <http://bugs.gnu.org/12471#8> (last line).
5084 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5085 (XParseGeometry): Now static. Substitute extremal values for
5086 values that are out of range.
5088 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5090 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5092 * nsfns.m (XParseGeometry): Remove.
5093 (Fx_create_frame): Call x_set_offset to correctly interpret
5094 top_pos in geometry.
5096 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5097 (Fx_parse_geometry): If there is a space in string, call
5098 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5100 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5102 * search.c (scan_buffer): Use character positions in calls to
5103 region_cache_forward and region_cache_backward, not byte
5104 positions. (Bug#12196)
5106 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5107 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5109 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5110 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5111 emacs_blocked_malloc, now deleted.
5113 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5115 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5116 The workaround was for improving performance on Solaris 2.4, but
5117 is getting in the way now. Emacs will still work if someone is
5118 still running Solaris 2.4 in a museum somewhere; Sun dropped
5119 support for Solaris 2.4 in 2003.
5120 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5121 * process.c (create_process) [HAVE_WORKING_VFORK]:
5122 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5123 since Emacs no longer uses vfork on that platform.
5125 2012-09-17 Glenn Morris <rgm@gnu.org>
5127 * emacs.c: Use COPYRIGHT.
5129 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5131 Remove configure's --without-sync-input option (Bug#12450).
5132 When auditing signal-handling in preparation for cleaning it up,
5133 I found that SYNC_INPUT has race conditions and would be a real
5134 pain to fix. Since it's an undocumented and deprecated
5135 configure-time option, now seems like a good time to remove it.
5136 Also see <http://bugs.gnu.org/11080#16>.
5137 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5138 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5139 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5140 (malloc_hysteresis):
5141 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5142 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5143 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5144 (dont_register_blocks, bytes_used_when_reconsidered)
5145 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5146 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5147 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5148 Remove. All uses removed.
5149 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5150 implementation, one that depends on whether the new macro
5151 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5153 * atimer.c (run_timers, handle_alarm_signal):
5154 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5155 (handle_async_input, process_pending_signals)
5156 (handle_input_available_signal, init_keyboard):
5157 * nsterm.m (ns_read_socket):
5158 * process.c (wait_reading_process_output):
5159 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5160 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5162 * xterm.c (XTread_socket):
5164 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5165 * eval.c (handling_signal): Remove. All uses removed.
5166 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5167 All uses replaced with the SYNC_INPUT version.
5168 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5170 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5173 * font.c (Ffont_shape_gstring): Remove unused local.
5175 2012-09-16 Glenn Morris <rgm@gnu.org>
5177 * Makefile.in (clean): No longer run nextstep's clean.
5179 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5181 (ns-app): Move here from ns.mk, and simplify.
5182 (clean): Simplify nextstep entry.
5183 * ns.mk: Remove file.
5185 2012-09-17 Kenichi Handa <handa@gnu.org>
5187 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5188 not covert the last few charactes.
5190 2012-09-16 Kenichi Handa <handa@gnu.org>
5192 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5193 here, but just check the validity of glyphs in the glyph-string.
5195 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5197 * window.c (Fwindow_parameter, Fset_window_parameter):
5198 Accept any window as argument (Bug#12452).
5200 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5202 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5203 to ns_term_init to avoid memory leak.
5205 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5206 explicit retain/release.
5207 (ns_term_init): Only allow one display. Initialize outerpool and
5210 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5212 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5213 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5214 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5215 the Microsoft problem in a different way, by altering ../nt/config.nt.
5217 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5232 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5233 by lisp.h. This completes removal of setjmp.h inclusion
5234 erroneously announced in the previous commit. (Bug#12446)
5236 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5239 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5240 not defined as a macro. The latter happens on MS-Windows.
5243 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5245 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5246 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5247 Some instances of '#include <setjmp.h>' removed, if the
5248 only reason for the instance was because "lisp.h" was included.
5249 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5250 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5251 and _longjmp with the new symbols. Emacs already uses _setjmp if
5252 available, so this change affects only POSIXish hosts that have
5253 sigsetjmp but not _setjmp, such as some versions of Solaris and
5254 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5255 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5256 (png_load_body) [HAVE_PNG]:
5257 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5258 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5259 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5260 since PNG requires jmp_buf. This is the only exception to the
5261 general rule that we now use sys_setjmp and sys_longjmp.
5262 This exception is OK since this code does not change the signal
5263 mask or longjmp out of a signal handler.
5265 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5267 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5268 Include "syssignal.h", for 'main_thread'.
5270 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5272 Avoid out-of-range marker position (Bug#12426).
5273 * insdel.c (replace_range, replace_range_2):
5274 Adjust markers before overlays, as suggested by comments.
5275 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5276 Remove redundant check before calling offset_intervals.
5278 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5280 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5281 current buffer (Bug#12387).
5283 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5285 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5287 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5289 Use a more backwards-compatible timer format (Bug#12430).
5290 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5291 vector element, not from the 4th, since PSECS is now at the end.
5292 (Fcurrent_idle_time): Doc fix.
5294 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5296 Function to mark objects and remove killed buffers at once.
5297 * alloc.c (discard_killed_buffers): Rename to ...
5298 (mark_discard_killed buffers) ... new name. Add marking
5299 of remaining objects. Fix comment. Adjust users.
5300 (mark_object): Do not touch frame buffer lists here.
5301 * frame.c (delete_frame): Reset frame buffer lists here.
5303 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5305 Better workaround for GNOME bug when --enable-gcc-warnings.
5306 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5307 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5308 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5310 Simplify SIGIO usage (Bug#12408).
5311 The code that dealt with SIGIO was crufty and confusing, e.g., it
5312 played tricks like "#undef SIGIO" but these tricks were not used
5313 consistently. Simplify mostly by not #undeffing standard symbols,
5314 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5315 or not as we please) rather than "defined SIGIO" (standard symbol
5316 that we probably shouldn't #undef).
5317 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5318 Modules that need it can include it.
5319 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5320 * dispextern.h (ignore_sigio): New decl.
5321 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5322 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5323 * emacs.c (shut_down_emacs):
5324 * keyboard.c (kbd_buffer_store_event_hold):
5325 Use ignore_sigio rather than invoking 'signal' directly.
5326 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5328 (FIONREAD, SIGIO): Do not #undef.
5329 (tty_read_avail_input): Use #error rather than a syntax error.
5330 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5331 for I_PIPE, used by SETUP_SLAVE_PTY.
5332 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5333 * sysdep.c (croak): Remove; no longer needed. This bit of
5334 temporary code, with Fred N. Fish's comment that it's temporary,
5335 has been in Emacs since at least 1992!
5336 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5337 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5338 * syssignal.h (croak): Remove decl.
5339 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5340 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5341 now that we're termios-only.
5342 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5343 * term.c (dissociate_if_controlling_tty): Use #error rather than
5346 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5347 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5348 to work around GNOME bug 683906.
5349 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5350 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5351 This works around GCC bug 54561.
5353 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5355 More fixes for 'volatile' and setjmp/longjmp.
5356 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5357 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5358 (png_load_body) [HAVE_PNG]:
5359 (jpeg_load_body) [HAVE_JPEG]:
5360 New function, with most of the old parent function's body.
5361 (png_load) [HAVE_PNG]:
5362 (jpeg_load) [HAVE_JPEG]:
5363 Invoke the new function, to avoid longjmp munging our locals.
5364 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5365 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5366 longjmp is passed 2, as the C standard doesn't guarantee this.
5367 Instead, store the failure code into mgr->failure_code.
5369 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5371 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5372 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5373 (syms_of_keyboard): Remove support for unread-command-char.
5375 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5377 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5378 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5379 violation. (Bug#12426)
5381 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5383 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5385 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5387 * eval.c: Add `inhibit-debugger'.
5388 (Qinhibit_debugger): New symbol.
5389 (call_debugger): Bind it instead of Qdebug_on_error.
5390 (maybe_call_debugger): Test Vinhibit_debugger.
5391 (syms_of_eval): Define inhibit-debugger.
5392 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5393 (syms_of_xdisp): Remove inhibit-debug-on-message.
5395 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5397 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5398 If a nonvolatile local variable is written before a _longjmp to
5399 the frame containing the variable, and is read after the _longjmp,
5400 the value read is indeterminate. Some local variables of type
5401 'struct handler' and 'struct catchtag' are used in this way, so
5402 mark each of their slots as volatile if the slot can be set before
5403 _longjmp and read afterwards.
5404 * lisp.h (struct handler): var and chosen_clause are now volatile.
5405 (struct catchtag): val, next, and pdlcount are now volatile.
5407 * bidi.c (bidi_push_it, bidi_pop_it):
5408 * fns.c (copy_hash_table):
5409 * image.c (define_image_type):
5410 * keyboard.c (kbd_buffer_store_event_hold):
5411 * process.c (Fprocess_send_eof):
5412 * xfaces.c (x_create_gc) [HAVE_NS]:
5413 * xgselect.c (xg_select):
5414 Prefer assignment to memcpy when either will do.
5416 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5417 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5418 time an item is removed. No need to mark this function 'inline';
5419 the compiler knows better than we do.
5421 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5423 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5424 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5425 to change_frame_size (Bug#12388).
5426 (windowDidResize:): Pass YES to updateFrameSize.
5428 * nsterm.h: Add delay parameter to updateFrameSize.
5430 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5432 Discard killed buffers from deleted window and frame objects.
5433 This reduces an amount of references to killed buffers and
5434 helps GC to reclaim them faster.
5435 * alloc.c (discard_killed_buffers): New function.
5436 (mark_object): Use it for deleted windows and frames.
5437 (mark_object): If symbol's value is set up for a killed buffer
5438 or deleted frame, restore its global binding.
5439 * data.c (swap_in_global_binding): Add GC notice.
5440 (swap_in_symval_forwarding): Use convenient set_blv_where.
5441 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5442 * window.h: ... to here.
5444 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5446 Convenient macro to check whether the buffer is live.
5447 * buffer.h (BUFFER_LIVE_P): New macro.
5448 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5449 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5451 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5453 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5454 composition cases (Bug#12364).
5456 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5457 overhang of succeeding glyphs overlapping box cursor.
5459 * w32term.c (x_draw_glyph_string): Likewise.
5461 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5463 Simplify, document, and port floating-point (Bug#12381).
5464 The porting part of this patch fixes bugs on non-IEEE platforms
5465 with frexp, ldexp, logb.
5466 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5468 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5469 support, by removing commented-out code and briefly listing the
5470 C89 functions excluded. The commented-out stuff was confusing
5471 maintenance, e.g., we thought we needed cbrt but it was commented out.
5472 (logb): Remove decl; no longer needed.
5473 (isfinite): New macro, if not already supplied.
5474 (isnan): Don't replace any existing macro.
5475 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5476 are present on all C89 platforms.
5477 (Ffrexp): Do not special-case zero, as frexp does the right thing
5479 (Flogb): Do not use logb, as it doesn't have the desired meaning
5480 on hosts that use non-base-2 floating point. Instead, stick with
5481 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5482 frexp, to avoid getting an unspecified result.
5484 * xdisp.c (Qinhibit_debug_on_message): Now static.
5486 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5488 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5489 NSBezierPath (Bug#12131).
5491 2012-09-10 Chong Yidong <cyd@gnu.org>
5493 * fns.c (Fdelq, Fdelete): Doc fix.
5495 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5497 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5498 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5500 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5502 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5503 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5506 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5508 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5509 left fringe if the window has a left margin. This avoids leaving
5510 traces of the cursor because its leftmost pixel is not drawn over.
5512 * dispnew.c (update_window_line): When the left margin area of a
5513 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5514 that screen line. (Bug#12277)
5516 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5518 Assume C89 or later for math functions (Bug#12381).
5519 This simplifies the code, and makes it a bit smaller and faster,
5520 and (most important) makes it easier to clean up signal handling
5521 since we can stop worring about floating-point exceptions in
5522 library code. That was a problem before C89, but the problem
5523 went away many years ago on all practical Emacs targets.
5524 * data.c, image.c, lread.c, print.c:
5525 Don't include <math.h>; no longer needed.
5526 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5527 might be autoconfigured, as that never happens.
5529 * doprnt.c (DBL_MAX_10_EXP):
5530 * print.c (DBL_DIG):
5531 Remove. C89 or later always defines these.
5532 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5533 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5534 (arith_error, domain_error, domain_error2):
5535 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5536 no longer needed -- we simply return what C returns. All uses removed.
5537 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5539 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5540 Remove. All uses expanded, as these macros are no longer used
5541 more than once and are now more trouble than they're worth.
5542 (Ftan): Use tan, not sin / cos.
5543 (Flogb): Assume C89 frexp.
5544 (fmod_float): Assume C89 fmod.
5545 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5546 (init_floatfns): Remove. All uses removed.
5548 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5550 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5551 compositeToPoint for OSX < 10.6 (Bug#12390).
5553 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5555 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5556 This produces more-accurate results.
5558 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5560 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5561 changes (Bug#12088).
5563 2012-09-08 Chong Yidong <cyd@gnu.org>
5565 * syntax.c (Fstring_to_syntax): Doc fix.
5567 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5569 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5570 in the internal border.
5571 (x_set_window_size): Remove static variables and their usage.
5572 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5573 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5574 Remove fringe/internal border adjustment (Bug#11052).
5575 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5576 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5577 (ns_fix_rect_ibw): Remove.
5578 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5579 (ns_dumpglyphs_box_or_relief): Ditto.
5580 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5582 (ns_dumpglyphs_image): Ditto.
5583 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5585 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5586 their usage. Add fringe_extended_p and its use as in other terms.
5587 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5588 scroll bar was removed.
5589 (updateFrameSize): New function.
5590 (windowDidResize): Move code to updateFrameSize and call it.
5592 * nsterm.h (EmacsView): Add updateFrameSize.
5594 2012-09-07 Chong Yidong <cyd@gnu.org>
5596 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5598 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5600 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5602 More signal-handler cleanup (Bug#12327).
5603 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5604 Problem introduced when merging patches. Noted by Eli Zaretskii in
5605 <http://bugs.gnu.org/12327#67>.
5606 * floatfns.c: Comment fix.
5607 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5608 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5609 and anyway the declaration is harmless even if SIGDANGER is not defined.
5610 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5611 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5612 source files not surprisingly expected syssignal.h to define, or
5613 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5614 Include <sys/ioctl.h>, for FIONREAD.
5615 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5616 This eliminates a problem whereby other files mysteriously had
5617 to include "syssignal.h" before including "systty.h" if they
5618 wanted to use "#ifdef SIGIO".
5620 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5622 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5624 * w32.c (sigemptyset): Empty the set.
5625 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5627 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5629 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5631 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5632 (mark_object): Likewise for frame objects.
5634 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5636 * syssignal.h (handle_on_main_thread): Always declare,
5637 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5638 This ports to platforms without HAVE_PTHREAD.
5640 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5642 Signal-handler cleanup (Bug#12327).
5643 Emacs's signal handlers were written in the old 4.2BSD style with
5644 sigblock and sigmask and so forth, and this led to some
5645 inefficiencies and confusion. Rewrite these to use
5646 pthread_sigmask etc. without copying signal sets around. Also,
5647 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5648 'signal', and instead use functions that do not attempt to take
5649 over the system name space. This patch causes Emacs's text
5650 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5651 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5652 Do not include <signal.h> or "syssignal.h", as these
5653 modules do not use signals.
5654 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5655 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5656 Do not include <signal.h>, as "syssignal.h" does that for us now.
5657 * atimer.c (sigmask_atimers): New function.
5658 (block_atimers, unblock_atimers): New functions,
5659 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5661 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5662 no longer needed here.
5663 * emacs.c (main): Inspect existing signal handler with sigaction,
5664 so that there's no need to block and unblock SIGHUP.
5665 * sysdep.c (struct save_signal): New member 'action', replacing
5666 old member 'handler'.
5667 (save_signal_handlers, restore_signal_handlers):
5668 Use sigaction instead of 'signal' to save and restore.
5669 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5670 New function. All users of 'signal' modified to use set_sighandler
5671 if they're writeonly, and to use sys_signal if they're read+write.
5672 (emacs_sigaction_init, forwarded_signal): New functions.
5673 (sys_signal): Remove. All uses replaced by calls to sigaction
5674 and emacs_sigaction_init, or by direct calls to 'signal'.
5675 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5676 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5677 all uses replaced by pthread_sigmask etc. calls.
5678 * syssignal.h: Include <signal.h>.
5679 (emacs_sigaction_init, forwarded_signal): New decls.
5680 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5681 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5682 (sigmask, sys_sigmask): Remove; no longer needed.
5683 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5684 (sigblock, sigunblock, sigfree):
5685 (sigsetmask) [!defined sigsetmask]:
5686 Remove. All uses replaced by pthread_sigmask.
5687 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5688 no longer need to be replaced, and its typical old uses
5689 are now done via emacs_sigaction_init and sigaction.
5690 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5691 (sys_sigdel): Remove; unused.
5692 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5694 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5696 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5697 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5699 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5701 Explicitly mark buffer_defaults and buffer_local_symbols.
5702 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5703 mark_local_symbols here.
5704 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5705 since special buffers aren't marked here any more.
5706 (allocate_buffer): Chain new buffer with all_buffers here...
5707 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5709 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5710 (syms_of_buffer): Remove staticpro of the above.
5711 (init_buffer_once): Set names for buffer_defaults and
5712 buffer_local_symbols.
5714 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5716 Use bool for booleans in font-related modules.
5717 * font.c (font_intern_prop, font_style_to_value)
5718 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5719 (generate_otf_features, font_check_otf_features, font_check_otf)
5720 (font_match_p, font_list_entities, font_at):
5721 * fontset.c (fontset_id_valid_p, reorder_font_vector
5722 (fontset_find_font, Fset_fontset_font)
5723 (face_suitable_for_char_p) [0]:
5724 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5725 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5726 (m17n_flt_initialized, ftfont_shape_by_flt):
5727 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5728 * nsfont.m (nsfont_draw):
5729 * w32font.c (w32font_draw):
5730 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5731 Use bool for booleans.
5732 * font.h: Adjust to above API changes.
5733 (struct font, struct font_driver, struct font_driver_list):
5734 Use bool for booleans.
5735 (struct font): Remove useless member encoding_type.
5737 * fontset.c, xftfont.c: Omit unnecessary static decls.
5739 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5741 * alloc.c (mark_object): Revert window marking code
5742 since it's unsafe for the Fset_window_configuration.
5744 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5746 Fix race conditions with signal handlers and errno (Bug#12327).
5747 Be more systematic about preserving errno whenever a signal
5748 handler returns, even if it's not in the main thread. Do this by
5749 renaming signal handlers to distinguish between signal delivery
5750 and signal handling. All uses changed.
5751 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5752 * data.c (deliver_arith_signal): Rename from arith_error.
5753 * dispnew.c (deliver_window_change_signal): Rename from
5754 window_change_signal.
5755 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5756 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5757 * keyboard.c (deliver_input_available_signal): Rename from
5758 input_available_signal.
5759 (deliver_user_signal): Rename from handle_user_signal.
5760 (deliver_interrupt_signal): Rename from interrupt_signal.
5761 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5762 (deliver_child_signal): Rename from sigchld_handler.
5763 * atimer.c (handle_alarm_signal):
5764 * data.c (handle_arith_signal):
5765 * dispnew.c (handle_window_change_signal):
5766 * emacs.c (handle_fatal_signal, handle_danger_signal):
5767 * keyboard.c (handle_input_available_signal):
5768 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5769 * process.c (handle_pipe_signal, handle_child_signal):
5770 New functions, with the actual signal-handling code taken from the
5771 original respective signal handlers, sans the sporadic attempts to
5772 preserve errno, since that's now done by handle_on_main_thread.
5773 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5774 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5775 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5777 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5778 Move initialization of main_thread to sysdep.c's init_signals.
5779 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5780 our usage, and simplifies the mainline code.
5781 (record_child_status_change): New static function, as a helper
5782 for handle_child_signal, and with most of the old child handler's
5784 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5785 (handle_child_signal): Use the above.
5786 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5787 Moved here from emacs.c.
5788 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5789 code moved here from emacs.c's main function.
5790 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5791 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5792 This lets callers save and restore errno properly.
5794 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5796 Remove redundant or unused things here and there.
5797 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5798 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5799 * editfns.c (Fcompare_buffer_substrings): Likewise.
5800 * frame.h (struct terminal, struct font_driver_list):
5801 Remove redundant declarations.
5802 * window.h (Qleft, Qright): Likewise.
5804 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5806 Do not mark objects from deleted buffers, windows and frames.
5807 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5808 (mark_object): Likewise for windows and frames.
5810 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5812 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5813 buffer_defaults and buffer_local_symbols as valid objects.
5814 Return special value to denote them.
5816 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5818 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5819 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5820 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5821 (file_name_absolute_p, Fsubstitute_in_file_name):
5822 (check_executable, check_writable, Ffile_accessible_directory_p)
5823 (Fset_file_selinux_context, Fdefault_file_modes)
5824 (Finsert_file_contents, choose_write_coding_system)
5825 (Fwrite_region, build_annotations, a_write, e_write)
5827 * filelock.c (boot_time_initialized, get_boot_time)
5828 (get_boot_time_1, lock_file_1, within_one_second):
5829 * floatfns.c (in_float):
5830 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5831 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5832 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5833 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5834 * window.c (compare_window_configurations):
5835 Use bool for booleans.
5836 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5837 (Fdefault_file_modes): Now mode_t, not int, for modes.
5838 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5839 (internal_delete_file): Now returns void, not a (boolean) int,
5840 since nobody was looking at the return value.
5841 * lisp.h, window.h: Adjust to above API changes.
5843 * xdisp.c (set_message): Simplify and reindent last change.
5845 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5847 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5849 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5851 * eval.c (call_debugger): Make the function non-static so that we
5852 can call it from set_message.
5854 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5855 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5857 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5859 Give more-useful info on a fatal error (Bug#12328).
5860 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5861 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5862 of doing the work ourselves.
5863 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5864 do most of the work.
5865 (fatal_error_backtrace): New function, taken from the guts
5866 of the old fatal_error_signal, but with a new option to output
5868 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5869 info about the signal than just its number.
5870 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5871 * sysdep.c: Include <execinfo.h>
5872 (emacs_backtrace): New function, taken partly from the previous
5873 code of the 'die' function.
5874 (emacs_abort): Call fatal_error_backtrace rather than abort.
5876 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5878 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5879 eager (load-time) macro-expansion.
5880 * lisp.mk (lisp): Add macroexp.
5882 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5884 Simplify redefinition of 'abort' (Bug#12316).
5885 Do not try to redefine the 'abort' function. Instead, redo
5886 the code so that it calls 'emacs_abort' rather than 'abort'.
5887 This removes the need for the NO_ABORT configure-time macro
5888 and makes it easier to change the abort code to do a backtrace.
5889 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5890 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5891 Remove; sysdep.c's emacs_abort now takes its place.
5892 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5893 'abort' changed to use 'emacs_abort'.
5894 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5895 (abort) [!defined abort]: Rename to ...
5896 (emacs_abort): ... new name.
5897 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5898 the place of the old 'abort' in emacs.c.
5899 * w32.c, w32fns.c (abort): Do not #undef.
5900 * w32.c (emacs_abort): Rename from w32_abort.
5902 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5904 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5905 offsets[j].dv, since the y axis of the screen coordinates points
5906 down, while the y axis of the font definition coordinates points
5907 up. This fixes display of Arabic diacritics such as KASRA and
5908 KASRATAN. (Bug#11860)
5910 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5912 Be more systematic about _setjmp vs setjmp.
5913 * alloc.c (test_setjmp, mark_stack):
5914 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5915 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5916 (png_load, my_error_exit, jpeg_load):
5917 * process.c (send_process_trap, send_process):
5918 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5919 The underscored versions are up to 30x faster on some hosts.
5920 Formerly, the code used setjmp+longjmp sometimes and
5921 _setjmp+_longjmp at other times, with no particular reason to
5922 prefer setjmp+longjmp.
5924 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5926 Fix minor problem found by static checking.
5927 * buffer.c (Fdelete_all_overlays): Return nil.
5929 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5931 * buffer.c (Fdelete_all_overlays): New function.

5935 * gtkutil.c: Add extern decl for Qxft.
5937 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5939 * emacs.c, eval.c: Use bool for boolean.
5940 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

5947 (maybe_call_debugger, Fbacktrace):
5948 * process.c (read_process_output, exec_sentinel):
5949 Use bool for booleans.
5950 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5951 All callers changed.
5952 * eval.c (interactive_p): Omit always-true boolean argument
5953 EXCLUDE_SUBRS_P. All callers changed.
5954 * dispextern.h, lisp.h: Reflect above API changes.
5955 * firstfile.c (dummy): Use the address of 'main', whose signature
5956 won't change, instead of the address of 'initialize', whose
5957 signature just changed from int to bool.
5958 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5959 * msdos.c (fatal_error_in_progress): ... from here.
5960 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5962 (redisplay_internal, unwind_redisplay): Simply clear
5963 REDISPLAYING_P when unwinding, instead of saving its previous,
5964 always-false value and then restoring it.
5966 Clean up some extern decls.
5967 Mostly, this hoists extern decls out of .c files and into .h files.
5968 That way, we're more likely to catch errors if the interfaces change.

5993 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5995 * xfaces.c: Remove unnecessary static decls.
5996 * xterm.c (updating_frame): Remove decl of nonexistent object.
5998 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5999 when building globals.h, as the objects that are not built on
6000 this host are not needed to compile C files on this host.
6002 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6004 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6030 (get_property_and_range, compare_string_intervals)
6031 (set_intervals_multibyte_1, set_intervals_multibyte):

6054 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6055 more than one grapheme cluster passed to the shaper: compute the
6056 offset adjustment values separately for each cluster. (Bug#11860)
6058 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6059 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6060 about implicit conversions from integer to pointer.
6062 2012-09-01 Daniel Colascione <dancol@dancol.org>
6064 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6065 system used too early.

6118 window system declarations.
6120 * frame.h: Move common functions here: set_frame_menubar,
6121 x_set_window_size, x_sync, x_get_focus_frame,
6122 x_set_mouse_position, x_set_mouse_pixel_position,
6123 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6184 * lread.c (init_lread): For out-of-tree builds, only add the
6185 source directory's site-lisp dir to the load-path if it exists,
6186 consistent with in-tree builds. (Bug#12302)

6379 Special MEM_TYPE_SPARE to denote reserved memory.
6380 * alloc.c (enum mem_type): New memory type.
6381 (refill_memory_reserve): Use new type for spare memory.
6382 This prevents live_cons_p and live_string_p from incorrect
6383 detection of uninitialized objects from spare memory as live.
6385 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6388 * Makefile.in (.PHONY): versioclean -> versionclean.
6390 Remove unused external symbols.
6391 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6392 * window.c (Qwindow_valid_p, decode_valid_window):
6393 Now static, not extern.
6394 * data.c (Qinterval): Remove; unused.
6395 (syms_of_data): Do not define 'interval'.
6396 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6397 * window.h (decode_valid_window):
6400 * character.c, charset.c, chartab.c: Use bool for booleans.
6401 * character.c (lisp_string_width, string_count_byte8)
6402 (string_escape_byte8):
6403 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6404 (load_charset_map_from_file, map_charset_chars)
6405 (Fdefine_charset_internal, define_charset_internal)
6406 (Fdeclare_equiv_charset, find_charsets_in_text)
6407 (Ffind_charset_region, char_charset, Fiso_charset):
6408 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6409 (sub_char_table_set, sub_char_table_set_range)
6410 (char_table_set_range, optimize_sub_char_table)
6411 (map_sub_char_table):
6412 Use bool for boolean.
6413 * character.c (str_to_unibyte): Omit last boolean argument; it was
6414 always 0. All callers changed.
6415 * character.h, charset.h: Adjust to match previous changes.
6416 * character.h (char_printable_p): Remove decl of nonexistent function.
6417 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6418 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6419 are all boolean, so make them single-bit bitfields.
6421 * lisp.h (ASET): Remove attempt to detect side effects.
6422 It was meant to be temporary and it often doesn't work,
6423 because when IDX has side effects the behavior of IDX==IDX
6424 is undefined. See Stefan Monnier in
6425 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6427 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6429 * lisp.h (functionp): New function (extracted from Ffunctionp).
6430 (FUNCTIONP): Use it.
6431 * eval.c (Ffunctionp): Use it.
6433 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6435 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6436 as that's faster and simpler than static storage. Don't bother
6437 with the g_main_context_query overhead if g_main_context_pending
6438 says no events are pending.
6439 (gfds, gfds_size): Remove these static vars.
6440 (xgselect_initialize): Remove; no longer needed.
6441 All uses and decls removed.
6443 * emacs.c (fatal_error_signal_hook): Remove.
6444 All uses removed. This leftover from old code was always 0.
6446 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6447 * casefiddle.c (casify_object, casify_region):
6448 * casetab.c (set_case_table):
6449 * category.c, category.h (word_boundary_p):
6450 * category.h (CHAR_HAS_CATEGORY):
6451 Use bool for booleans, instead of int.
6453 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6455 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6457 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6459 On assertion failure, print backtrace if available.
6460 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6461 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6462 * Makefile.in (LIB_EXECINFO): New macro.
6465 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6466 * bytecode.c (exec_byte_code):
6467 * callint.c (check_mark, Fcall_interactively):
6468 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6469 (getenv_internal, sync_process_alive, call_process_exited):
6470 * lisp.h (USE_SAFE_ALLOCA):
6471 Use bool for booleans, instead of int.
6472 * lisp.h, process.h: Adjust prototypes to match above changes.
6473 * callint.c (Fcall_interactively): Don't assume the mark's
6474 offset fits in 'int'.
6476 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6478 * buffer.c, buffer.h: Use bool for boolean.
6479 * buffer.c (reset_buffer_local_variables)
6480 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6481 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6482 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6483 (overlay_touches_p, overlay_strings, Foverlay_put)
6484 (report_overlay_modification, call_overlay_mod_hooks):
6485 (mmap_enlarge, mmap_set_vars):
6486 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6487 Use bool for booleans, instead of int.
6488 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6489 since the 1-or-0 return value is always ignored anyway.
6490 (mmap_initialized_p):
6491 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6492 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6494 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6496 * bidi.c: Use bool for boolean.
6497 This is a bit more readable, and makes the text segment of bidi.o
6498 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6499 Presumably it's faster too.
6500 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6502 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6503 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6504 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6505 (bidi_explicit_dir_char, bidi_level_of_next_char)
6506 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6507 Use bool for booleans, instead of int.
6508 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6509 (bidi_unshelve_cache): Adjust decls to match code.
6511 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6513 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6516 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6518 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6519 * atimer.h: Include <stdbool.h>.
6521 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6523 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6524 compile time tests instead of run time tests on systems that do
6526 (FRAME_MAC_P): Remove leftover from deleted code.
6527 * frame.c (syms_of_frame): Remove leftover from deleted code.
6529 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6531 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6533 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6535 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6536 Otherwise, the compiler complains about (A?B:C) where B is void
6537 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6538 (fontset_add): Return void, for FONTSET_ADD.
6540 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6542 * alloc.c: Use bool for booleans.
6543 (gc_in_progress, abort_on_gc)
6544 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6545 (dont_register_blocks) [GC_MALLOC_CHECK]:
6546 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6547 (check_string_bytes, make_specified_string, memory_full)
6548 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6549 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6550 (mark_stack, valid_pointer_p, make_pure_string)
6551 (Fgarbage_collect, survives_gc_p, gc_sweep):
6552 Use bool for booleans, instead of int.
6553 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6554 Remove unused local.
6555 * alloc.c (PURE_POINTER_P):
6556 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6557 * editfns.c (Fformat):
6558 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6560 * fns.c (sweep_weak_table):
6561 * lisp.h (suppress_checking, push_message, survives_gc_p)
6562 (make_pure_string, gc_in_progress, abort_on_gc):
6563 * lread.c (readchar, read1):
6564 * print.c (Fprin1_to_string):
6565 * xdisp.c (push_message):
6566 Use bool for booleans affected directly or indirectly by
6569 Make recently-introduced setters macros.
6570 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6571 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6572 (set_fontset_default, set_fontset_fallback): Rename from their
6573 upper-case counterparts, and make them functions rather than macros.
6574 This is more consistent with the other recently-introduced setters.
6575 These don't need to be inline, since they're local.
6577 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6579 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6580 the loop (Bug#12247).
6582 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6584 * lisp.h (vcopy): Use memcpy rather than our own loop.
6585 This fixes a performance regression introduced by the recent
6586 addition of vcopy. This means 'vcopy' will need to be modified
6587 for a copying collector, but that's OK. Also, tighten the
6588 checking in the assertion.
6590 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6592 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6593 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6594 non-base glyph for the width of the base character, according to
6595 what x_draw_composite_glyph_string_foreground expects.
6596 Generate WADJUST value according to composition_gstring_width's
6597 expectations, to produce correct width of the composed character.
6598 Reverse the sign of the DU offset produced by ScriptPlace.
6600 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6602 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6604 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6606 Avoid direct writes to contents member of struct Lisp_Vector.
6607 * lisp.h (vcopy): New function to copy data into vector.
6608 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6609 * fns.c (Ffillarray): Use ASET.
6610 * keyboard.c (timer_check_2): Use AREF and ASET.
6611 (append_tool_bar_item, Frecent_keys): Use vcopy.
6612 * lread.c (read_vector): Use ASET.
6613 * msdos.c (Frecent_doskeys): Use vcopy.
6614 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6615 (Finternal_merge_in_global_face): Use ASET and vcopy.
6616 * xfont.c (xfont_list_pattern): Likewise.
6618 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6620 * window.c (Fwindow_point): For the selected window always return
6621 the position of its buffer's point.
6622 (Fset_window_point): For the selected window always go in its
6623 buffer to the specified position.
6625 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6627 Setter macros for fontsets.
6628 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6629 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6630 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6633 2012-08-20 Glenn Morris <rgm@gnu.org>
6635 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6636 Don't assume that `ln -f' works.
6638 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6640 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6641 and later about non-assignments with no effect. See discussion at
6642 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6645 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6647 Inline setter functions for Lisp_Objects slots of struct specbinding.
6648 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6651 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6653 * window.c (select_window): Always make selected window's buffer
6656 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6658 Use AREF and ASET for docstrings of category tables.
6659 * category.h (CATEGORY_DOCSTRING): Use AREF.
6660 (SET_CATEGORY_DOCSTRING): Use ASET.
6661 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6663 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6665 Inline setter functions for hash table members.
6666 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6667 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6668 (set_hash_key_and_value, set_hash_index, set_hash_next)
6669 (set_hash_hash): New functions.
6670 * charset.c, fns.c: Adjust users.
6672 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6674 Inline getter and setter functions for per-buffer values.
6675 * buffer.h (per_buffer_default, set_per_buffer_default)
6676 (per_buffer_value, set_per_buffer_value): New functions.
6677 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6678 * buffer.c, data.c: Adjust users.
6680 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6682 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6684 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6686 Rely on <config.h> + <unistd.h> to declare 'environ',
6687 as gnulib does this if the system doesn't.
6688 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6689 Remove declaration. MS-Windows declares it on stdlib.h which is
6690 included by conf_post.h.
6691 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6692 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6693 * vm-limit.c: Include <unistd.h>, for 'environ'.
6695 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6696 (start_of_data): Remove decl; mem-limits.h provides it.
6698 * xdisp.c (handle_invisible_prop): Make it a bit faster
6699 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6701 2012-08-19 Chong Yidong <cyd@gnu.org>
6703 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6706 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6708 * .gdbinit: Use call instead of set when calling a function in the
6711 * data.c (set_internal): Don't use set_blv_found.
6712 (Fkill_local_variable): Likewise.
6714 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6716 * nsfont.m (ns_ascii_average_width): Ensure the string
6717 ascii_printable is initialized with a null-terminated character
6718 array. Otherwise, it can contain undesired extra characters.
6720 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6722 port new setting code to Sun C 5.8 2005/10/13
6723 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6724 Return void, not Lisp_Object. Otherwise, the compiler
6725 complains about (A?B:C) where B is void and C is Lisp_Object
6726 when compiling CHAR_TABLE_SET, due to the recent change to
6727 the API of sub_char_table_set_contents.
6729 2012-08-18 Chong Yidong <cyd@gnu.org>
6731 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6732 for the string case (Bug#3874).
6734 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6736 * buffer.h (BSET): Remove (Bug#12215).
6737 Replace all uses with calls to new setter functions.

6766 * syntax.c (bset_syntax_table):
6767 New setter functions.
6769 * process.h (PSET): Remove (Bug#12215).
6770 Replace all uses with calls to new setter functions.

6782 (pset_type, pset_write_queue): New setter functions.
6784 * window.h (WSET): Remove (Bug#12215).
6785 Replace all uses with calls to new setter functions.
6786 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
6787 (WINDOW_INLINE): New macro.

6806 New setter functions.
6808 * termhooks.h (TSET): Remove (Bug#12215).

7564 value of EMACSLOADPATH, as it is no longer needed.
7565 (check_windows_init_file): Now external, not static.

7571 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7616 * alloc.c (record_xmalloc): New function.
7617 * lisp.h (record_xmalloc): New decl.
7618 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7619 more like a function. This is because the pointer cast is not
7620 needed. All uses changed.
7621 * print.c (print_string, print_error_message): Avoid length recalc.
7623 Improve fix for macroexp crash with debugging (Bug#12118).
7624 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7625 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7626 not supposed to be invoked from the garbage collector.

7628 (gc_aset): New function, which is like ASET but can be
7629 used in the garbage collector.

7658 with addition of handling of symlinks and support for 'lstat'.
7659 If possible, get file's attributes and security information by
7660 handle, not by name. Produce S_IFLNK bit for symlinks, when
7661 called from 'lstat'.
7662 (stat, lstat): New functions, call 'stat_worker'.
7663 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7664 symlinks when the underlying filesystem supports them.
7666 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7668 Fix macroexp crash on Windows with debugging (Bug#12118).
7669 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7670 checking subscripts; problem introduced with the recent
7671 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7672 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7673 since it's used in non-static inline functions now.
7675 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7676 Don't assume buffer size fits in 'int'. Remove unused local.

8147 enumeration constants, as PURE and HEAP are too general, and clash
8148 with other headers and sources, such as gmalloc.c and the
8149 MS-Windows system headers. All users changed.
8151 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8153 Revert last save_excursion_save and save_excursion_restore changes.
8154 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8164 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8166 Improve GDB symbol export (Bug#12036).
8167 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8168 arms of an 'if', not using conditional expressions; otherwise GDB
8169 complains about the types in the unevaluated arm when the argument
8170 is an integer literal.
8171 (xgetint): Simplify expression.
8172 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8173 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8174 Zaretskii in <http://bugs.gnu.org/12036#13>.
8175 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8176 needed now that we have gdb_make_enums_visible.
8177 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8178 (enum enum_USE_LSB_TAG):
8179 New enum types, packaging up enums that need to be exported to GDB.
8181 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8183 Utility function to make a list from specified amount of objects.

8185 (listn): New prototype.
8186 * alloc.c (listn): New function.

8197 * xdisp.c (syms_of_xdisp): Likewise.
8198 * xfns.c (syms_of_xfns): Likewise.
8200 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8202 Fast save_excursion_save and save_excursion_restore.
8203 * lisp.h (struct Lisp_Excursion): New data type.
8204 (PVEC_EXCURSION): New pseudovector type.
8205 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8206 to deal with it. Adjust comments.
8207 (init_marker, attach_marker): New prototype.
8208 (unchain_marker): Adjust prototype.
8209 * marker.c (attach_marker): Change to global.

8217 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8219 Fix export of symbols to GDB (Bug#12036).
8220 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8221 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8222 emacs.c, as this is a more-suitable home. Had this been done earlier
8223 the fix for 12036 would have avoided some of the problems noted in
8224 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8225 would have been more obvious.
8226 * emacs.c: Do not include <verify.h>; no longer needed.
8227 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8228 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8229 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8230 Remove; now done in lisp.h.
8231 * lisp.h (PUBLISH_TO_GDB): New macro.
8232 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8233 (DATA_SEG_BITS): Use it.
8234 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8235 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8236 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8237 not be usable in #if. This simplifies things.
8239 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8241 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8243 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8245 Simplify export of symbols to GDB (Bug#12036).
8246 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8247 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8248 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8249 Adjust to changes in lisp.h and emacs.c, by using
8250 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8251 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8252 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8253 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8254 instead of gdb_valbits.
8255 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8256 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8257 instead of gdb_array_mark_flag.
8258 (xboolvector): Get size from $->size, not $->header.size.
8259 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8260 (xreload, hook-run, hookpost-run): Remove.
8261 * emacs.c: Include <verify.h>.
8262 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8263 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8265 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8266 (gdb_USE_LSB_TAG): New enum constants.
8267 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8268 Also define these as enum constants, so they're visible to GDB.
8269 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8270 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8271 as constants, so they're visible to GDB.
8272 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8273 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8274 Now enum constants, not macros, so they're visible to GDB.
8275 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8276 more convenient now. All uses changed.
8277 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8278 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8280 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8285 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8287 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8288 add argument, tune behavior, and adjust all callers.
8290 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8292 Use typedef for EMACS_INT, EMACS_UINT.
8293 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8294 than macros. This simplifies debugging in the usual case, since
8295 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8296 and it allows expressions involving EMACS_INT casts.
8297 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8299 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8301 * nsterm.m (ns_read_socket): Return early if there is a modal

8307 that FOCUS-FRAME can be omitted.
8309 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8311 Adjust buffer text indirection counters at the end of Fkill_buffer.
8312 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8313 buffer is definitely dead. This should really fix an issue reported
8314 by Christoph Scholtes again. (Bug#12007).
8315 (init_buffer_once): Initialize indirection counters of
8316 buffer_defaults and buffer_local_symbols (for sanity and safety).
8318 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8320 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8321 and continuation glyphs on tooltip frames, leave them at zero.
8322 Avoids continued lines in tooltips. (Bug#11832)
8324 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8326 Simplify copy_overlay.
8327 * buffer.c (copy_overlay): Simplify. Use build_marker.

8349 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8351 Swap buffer text indirection counters in Fbuffer_swap_text.
8352 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8353 This avoids crash reported by Christoph Scholtes at
8354 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8356 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8358 * nsmenu.m (Popdown_data): New struct.
8359 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8361 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

8363 and autorelease them. Also autorelease img and matrix (Bug#12005).
8364 (dealloc): Remove (Bug#12005).

8381 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8383 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8384 as it's limited by the amount of memory, not by INT_MAX.
8386 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8388 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8389 in special-event-map. See the discussion at

8448 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8449 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8450 Adjust users accordingly.
8451 * font.h (font_open_by_name): Adjust prototype.

8469 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8470 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8471 'for_each_per_buffer_object_at'.
8472 All uses changed. It's better to use upper-case for macros that
8473 cannot be implemented as functions, to give the reader a clue
8474 that they're special.
8476 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8478 * alloc.c (Fgarbage_collect): Tweak docstring.

8519 * intervals.c (merge_interval_right, merge_interval_left):
8520 Do not zero out this interval if it is absorbed by its children,
8521 as this interval's total length doesn't change in that case. See
8522 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8524 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8526 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8527 when invoking (make-bool-vector N t) and N is a positive
8528 multiple of 8 -- the last 8 bits were mistakenly cleared.
8530 Remove some struct layout assumptions in bool vectors.
8531 * alloc.c (bool_header_size): New constant.
8532 (header_size, word_size): Move earlier, as they're now used earlier.

8534 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
8535 padding before the data member of a bool vector.
8536 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
8537 than doing the check by hand with an abort ().
8539 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8541 * eval.c (Fdefvar): Don't check constants since we only set the var if
8542 it's not yet defined anyway (bug#11904).
8544 * lisp.h (last_undo_boundary): Declare new var.
8545 * keyboard.c (command_loop_1): Set it.
8546 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8547 were auto-added by the command loop (bug#11774).
8549 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
8551 * w32font.c (Qsymbol): Remove local definition.

9040 2012-07-11 Glenn Morris <rgm@gnu.org>
9042 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9043 since nothing has defined it on these platforms.
9045 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
9046 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

9050 Move CLASH_DETECTION to configure.
9052 * s/gnu.h: Remove file, which is now empty.
9054 * s/gnu.h, s/gnu-linux.h:
9055 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
9057 2012-07-11 John Wiegley <johnw@newartisans.com>
9059 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9060 function attribute, so we only use it if it exists in the
9063 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9065 Avoid call to strlen in fast_c_string_match_ignore_case.
9066 * search.c (fast_c_string_match_ignore_case): Change to use
9067 length argument. Adjust users accordingly.
9068 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
9070 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>
9072 Assume mkdir, rmdir.

9111 Remove "#define unix" that is no longer needed (Bug#11905).
9112 * s/aix4-2.h (unix): Remove; no longer needed.
9114 EMACS_TIME simplification (Bug#11875).
9115 This replaces macros (which typically do not work in GDB)
9116 with functions, typedefs and enums, making the code easier to debug.
9117 The functional style also makes code easier to read and maintain.
9118 * systime.h: Include <sys/time.h> on all hosts, not just if
9119 WINDOWSNT, since 'struct timeval' is needed in general.
9120 (EMACS_TIME): Now a typedef, not a macro.
9121 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9123 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9125 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9126 (EMACS_TIME_LE): Now functions, not macros.
9127 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9128 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9129 which are not functions. All uses rewritten to use:
9130 (make_emacs_time): New function.
9131 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9132 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9133 not functions. All uses rewritten to use the following, respectively:
9134 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9135 (add_emacs_time, sub_emacs_time): New functions.
9136 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9137 * fileio.c (Fcopy_file):
9138 * xterm.c (XTflash): Get the current time closer to when it's used.
9139 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9147 * gtkutil.c (get_utf8_string):
9149 * nsmenu.m (ns_update_menubar):
9150 * regex.c (regerror):
9151 Prefer memcpy to strncpy and strncat when either will do.
9152 * fileio.c (Fsubstitute_in_file_name):
9153 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9154 (menu_separator_name_p):
9155 * nsmenu.m (ns_update_menubar):
9156 Prefer memcmp to strncmp when either will do.
9157 * nsterm.m: Include <ftoastr.h>.
9159 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9160 Prefer snprintf to strncpy.
9161 * nsterm.m (ns_term_init):
9162 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9163 * nsterm.m (ns_term_init):
9164 Avoid the need for strncpy, by using build_string or
9165 make_unibyte_string directly. Use dtoastr, not snprintf.
9166 * process.c (Fmake_network_process): Diagnose service names that
9167 are too long, rather than silently truncating them or creating
9168 non-null-terminated names.
9169 (Fnetwork_interface_info): Likewise, for interface names.
9170 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9171 Prefer sprintf to strncat.
9172 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9173 Prefer vsnprintf to vsprintf + strncpy.
9175 2012-07-10 Glenn Morris <rgm@gnu.org>
9177 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9178 Clarify fallback case.
9180 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9182 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9183 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9184 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9185 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9186 where argument type is known to be a Lisp_Cons.
9188 2012-07-10 Tom Tromey <tromey@redhat.com>
9190 * bytecode.c (BYTE_CODE_THREADED): New macro.
9191 (BYTE_CODES): New macro. Replaces all old byte-code defines.

9198 Optimize pure C strings initialization.
9199 * lisp.h (make_pure_string): Fix prototype.
9200 (build_pure_c_string): New function, defined as static inline. This
9201 provides a better opportunity to optimize away calls to strlen when
9202 the function is called with compile-time constant argument.
9203 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9204 argument, adjust users accordingly. Use build_pure_c_string where
9206 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9207 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9208 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9210 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9212 Avoid calls to strlen in miscellaneous functions.
9213 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9214 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9215 * lread.c (openp): Likewise.
9217 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9219 Avoid calls to strlen in path processing functions.
9220 * fileio.c (file_name_as_directory): Add comment. Change to add
9221 srclen argument and return the length of result. Adjust users
9223 (directory_file_name): Fix comment. Change to add srclen argument,
9224 swap 1st and 2nd arguments to obey the common convention.
9225 Adjust users accordingly.
9226 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9228 2012-07-10 Glenn Morris <rgm@gnu.org>
9230 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9231 Move PENDING_OUTPUT_COUNT definition to configure.
9233 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9234 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9235 * s/gnu.h (DATA_START): Move definitions to configure.
9237 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9238 We include usg5-4-common.h, which defines them both.
9240 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9241 O_RDONLY already includes it).
9243 Stop ns builds setting the EMACSLOADPATH environment variable.
9244 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9245 Now it does not set EMACSLOADPATH, just returns the load-path string.
9246 * nsterm.h: Update accordingly.
9247 * lread.c [HAVE_NS]: Include nsterm.h.
9248 (init_lread) [HAVE_NS]: Use ns_load_path.
9249 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9251 2012-07-09 Glenn Morris <rgm@gnu.org>
9253 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9254 since the included bsd-common.h does so.
9256 Stop ns builds setting the EMACSPATH environment variable.
9257 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9258 (ns_init_paths): Do not set EMACSPATH.
9259 * nsterm.h (ns_exec_path): Add it.
9260 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9263 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9265 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9267 * process.c (wait_reading_process_output): 'waitchannels' was unset
9268 when read_kbd || !NILP (wait_for_cell); fix this.
9270 Add GCC-style 'const' attribute to functions that can use it.
9271 * character.h (char_resolve_modifier_mask):
9272 * keyboard.h (make_ctrl_char):
9273 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9274 (init_character_once, next_almost_prime, init_fns, init_image)
9275 (flush_pending_output, init_sound):
9276 * mem-limits.h (start_of_data):

9280 Declare the dummy function with ATTRIBUTE_CONST.
9281 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9282 Add decls with ATTRIBUTE_CONST.
9284 Minor improvements to make_formatted_string.
9285 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9286 where int is good enough, as vsprintf returns an int.
9287 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9289 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9291 Use make_formatted_string to avoid double length calculation.
9292 * lisp.h (make_formatted_string): New prototype.

9299 (x_report_frame_params): Likewise.
9300 * image.c (gs_load): Likewise.
9301 * minibuf.c (get_minibuffer): Likewise.

9316 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9318 Move marker debugging code under MARKER_DEBUG.
9319 * marker.c (MARKER_DEBUG): Move marker debugging code under
9320 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9321 for bootstrap with --enable-checking (~3x slowdown reported
9322 by Juanma Barranquero <lekktu@gmail.com>).
9323 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9325 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9327 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9328 See <http://bugs.gnu.org/11825#29>.
9330 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9332 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9333 has no font, use the frame's font. (Bug#11813)
9334 (display_line): Add commentary about displaying truncation glyphs
9336 (produce_special_glyphs): Move here from term.c.
9338 * term.c (produce_special_glyphs): Move to xdisp.c.
9340 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9343 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9345 * xdisp.c (display_line): Avoid warning about implicit declaration
9348 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9350 * lisp.h: Remove empty conditional.
9352 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9354 * lread.c (load_path_check): Now static.
9356 Fix some minor --with-ns problems found by static checking.
9357 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9358 (x_set_font) [!HAVE_X_WINDOWS]:
9359 * image.c (xpm_load_image) [HAVE_NS]:
9360 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9361 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9362 Remove unused local.
9363 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9364 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9365 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9366 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9367 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9368 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9369 Fix pointer signedness problem.
9370 * xfaces.c (FRAME_X_FONT_TABLE):
9371 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9373 2012-07-07 Glenn Morris <rgm@gnu.org>
9375 * lread.c (load_path_check): New function, split from init_lread.
9376 (init_lread): Reorganize. Motivation:
9377 If EMACSLOADPATH is set, check/warn about that rather than the
9378 defaults, which we are not going to use. Hence we can remove
9379 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9380 Don't warn if site-lisp directories are missing.
9381 If not installed, start from a blank load-path, since
9382 PATH_LOADSEARCH refers to the eventual installation directories.
9384 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9386 Support truncation and continuation glyphs on GUI frames, when
9387 fringes are disabled. (Bug#11832)
9388 * xdisp.c (init_iterator): Get dimensions of truncation and
9389 continuation glyphs even if on GUI frames.
9390 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9391 or both, are absent.
9392 (start_display, move_it_in_display_line_to): Handle the case of a
9393 GUI frame without a fringe to display continuation or truncation
9395 (insert_left_trunc_glyphs): Support GUI frames: make sure
9396 truncation glyphs overwrite enough glyphs from the current line to
9397 have sufficient space in pixels.
9398 (display_line): Support truncation and continuation glyphs on GUI
9399 frames. If some spare pixels are left on the line after inserting
9400 the truncation glyphs, fill that space with a stretch glyph of a
9401 suitably computed width.
9403 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9404 produce_glyphs, to support GUI sessions.
9406 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9408 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9410 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9412 Do not require float-time's arg to fit in time_t (Bug#11825).
9413 This works better on hosts where time_t is unsigned, and where
9414 float-time is applied to the (negative) difference between two times.
9415 * editfns.c (decode_time_components): Last arg is now double *,
9416 not int *, and means to store all the result as a double, without
9417 worrying about whether the seconds part fits in time_t.
9418 All callers changed.
9419 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9420 All callers changed.
9421 (Ffloat_time): Do not fail merely because the specified time falls
9422 outside of time_t range.
9424 2012-07-07 Glenn Morris <rgm@gnu.org>
9426 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9430 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9432 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9433 Update dependencies.
9435 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9437 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9439 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9440 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9441 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9442 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9443 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9444 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9446 * xfont.c (compare_font_names): Redo to omit the need for casts.
9448 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9450 * xfns.c (Fx_change_window_property): Doc fix.
9451 * w32fns.c (Fx_change_window_property): Doc fix.
9453 * w32fns.c (Fx_window_property): Accept the same arguments as the
9454 X Windows version. Doc fix.
9455 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9457 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9458 Eli Zaretskii <eliz@gnu.org>
9460 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9461 Windows-specific code from nt/config.nt moved here.
9462 Obsolete settings removed.
9464 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9466 * process.c: Avoid unnecessary calls to gettime.
9467 (wait_reading_process_output): Don't get the time of day
9468 when gobbling data immediately and not waiting, as there's no need
9469 for it in that case. This removes a FIXME.
9471 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9473 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9474 is defined (Bug#11768).
9476 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9478 Fix marker debugging code.
9479 * marker.c (byte_char_debug_check): Do not perform the check
9480 if buffer is not multibyte.
9481 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9482 Call byte_char_debug_check with correct arguments.
9484 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9486 Compile marker debugging code only if ENABLE_CHECKING is defined.
9487 * marker.c (byte_char_debug_check, count_markers):
9488 Use only if ENABLE_CHECKING is defined.
9489 (byte_debug_flag): Remove.
9490 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9491 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9493 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9495 Avoid code repetition in marker-related functions.
9496 * marker.c (attach_marker): New function.
9497 (Fset_marker, set_marker_restricted, set_marker_both)
9498 (set_marker_restricted_both): Use it.
9499 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9500 Consistently rename charno to charpos.
9501 (marker_position): Add eassert.
9502 (marker_byte_position): Convert to eassert.
9504 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9506 Simplify list operations in unchain_overlay and unchain_marker.
9507 * buffer.c (unchain_overlay): Simplify. Add comment.
9508 * marker.c (unchain_marker): Simplify. Fix comments.
9510 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9512 Introduce fast path for the widely used marker operation.
9513 * alloc.c (build_marker): New function.
9514 * lisp.h (build_marker): New prototype.
9515 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9516 * composite.c (autocmp_chars): Likewise.
9517 * editfns.c (buildmark): Remove.
9518 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9519 (save_restriction_save): Use build_marker.
9520 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9521 * window.c (save_window_save): Likewise.
9523 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9526 to avoid redundant calls to unchain_overlay.
9527 * buffer.c (drop_overlay): New function.
9528 (delete_all_overlays, Fdelete_overlay): Use it.
9529 * minibuf.c (get_minibuffer): Fix comment.
9531 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9533 Port to OpenBSD 5.1 amd64.
9534 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9535 This is needed for OpenBSD, and should be harmless on all BSD systems.
9536 Also, include <sys/sysctl.h>, as it should be available on all
9537 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9538 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9539 use p_pid member, not kp_proc.pid.
9541 2012-07-06 Glenn Morris <rgm@gnu.org>
9543 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9545 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9547 More xmalloc and related cleanup.
9548 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9555 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9556 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9558 Omit needless casts involving void * pointers and allocation.
9559 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9560 as the former is more robust if P's type is changed.
9561 Prefer xzalloc to xmalloc + memset 0.
9562 Simplify malloc-or-realloc to realloc.
9563 Don't worry about xmalloc returning a null pointer.
9564 Prefer xstrdup to xmalloc + strcpy.
9565 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9567 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9568 alloca of a constant.
9570 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9572 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9573 hscroll is larger than the line width. Fixes long and futile
9574 looping inside extend_face_to_end_of_line (on a TTY) producing
9575 glyphs that are not needed and thrown away.
9577 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9579 * marker.c (set_marker_restricted_both): Simplify by using
9582 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9584 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9586 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9588 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9589 not defined (Bug#11768).

9591 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9592 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9593 followed by gtk_box_set_homogeneous (Bug#11768).
9594 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9595 (update_theme_scrollbar_width, xg_create_scroll_bar):
9596 Use gtk_scrollbar_new (Bug#11768).
9597 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9598 (is_box_type): New function (Bug#11768).
9599 (xg_tool_item_stale_p): Call is_box_type.
9600 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9601 with default display (Bug#11768).

9605 * xdisp.c (window_hscroll_limited): New function.
9606 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9607 coordinates when window's hscroll is set to insanely large
9610 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9612 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9618 * lisp.h (xzalloc): New prototype. Omit needless casts.
9619 * alloc.c (xzalloc): New function. Omit needless casts.

9671 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9673 * fileio.c (time_error_value): Check the right error number.
9674 Problem reported by Troels Nielsen in
9675 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9677 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9679 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9680 This should be fixed in a better way; see Eli Zaretskii in
9681 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9682 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9684 * fileio.c (time_error_value): Rename from special_mtime.
9685 The old name's problems were noted by Eli Zaretskii in
9686 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9688 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9689 This variable's comment says Emacs needs at least one GDB-visible
9690 symbol of type enum pvec_type, to work around GDB problems.
9691 The symbol's value doesn't matter.
9693 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9694 that causes compilation to fail on pre-C99 compilers.
9696 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9698 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9699 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9701 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9703 * buffer.c (init_buffer_once): Fix initialization of
9704 headers for buffer_defaults and buffer_local_symbols.
9705 Reported by Juanma Barranquero <lekktu@gmail.com>.
9707 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9709 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9710 * lisp.h (enum pvec_type): Use fewer bits.
9711 (PSEUDOVECTOR_SIZE_BITS): New constant.
9712 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9713 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9714 change in pvec_type.
9715 (PSEUDOVECTOR_TYPEP): New macro.
9716 (TYPED_PSEUDOVECTORP): Use it.
9717 * fns.c (internal_equal): Adapt code to extract pvectype.

9721 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9722 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9723 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9724 abusing vector->header.next.nbytes.
9725 (live_vector_p): Use PVEC_TYPE.
9726 (mark_object): Adapt code to extract pvectype. Use switch.
9728 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9730 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9731 Tighten new eassert a bit.
9733 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9735 Fix compilation with --enable-gcc-warnings and -O1
9737 * doprnt.c (doprnt): Change type of tem to int, initialize
9738 to avoid compiler warning. Add eassert.
9739 * search.c (simple_search): Initialize match_byte to avoid
9740 compiler warning. Add eassert.
9742 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9744 Avoid weird behavior with large horizontal scrolls.
9745 Without this change, for example, large hscroll values would
9746 mess up Emacs's display on Fedora 15 x86, presumably due to
9747 overflows in int calculations in the display code.
9748 Also, if buffers had long lines, Emacs would freeze.
9749 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9750 (set_window_hscroll): New function, containing the old guts of
9751 Fset_window_hscroll. Return the clipped value.
9752 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9753 This avoids the need to check against PTRDIFF_MAX.
9755 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9757 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9759 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9761 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9763 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9764 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9765 since GCC 4.4.6 issues a bogus warning for them.
9767 Fix bugs in file timestamp newness comparisons.
9768 * fileio.c (Ffile_newer_than_file_p):
9769 * lread.c (Fload): Use full timestamp resolution of files,
9770 not just the 1-second resolution, so that files that are only
9771 slightly newer still count as newer.
9772 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9773 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9775 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9777 * fileio.c: Improve handling of file time marker. (Bug#11852)
9778 (special_mtime): New function.
9779 (Finsert_file_contents, Fverify_visited_file_modtime):
9780 Use it to set special mtime values consistently.
9782 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9784 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9785 marker for non-existing file. (Bug#11852)
9787 2012-07-03 Glenn Morris <rgm@gnu.org>
9789 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9790 and did not make it into globals.h).
9792 2012-07-03 Tom Tromey <tromey@redhat.com>
9794 * window.c (Fset_window_margins, Fset_window_fringes)
9795 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9796 * textprop.c (Fprevious_property_change): No longer static.
9797 * syntax.c (Fsyntax_table_p): No longer static.

9819 * intervals.h: Remove EXFUNs.
9820 * fontset.h: Remove EXFUN.

9825 * w32term.h: Remove EXFUNs.
9826 * window.h: Remove EXFUNs.
9827 * xsettings.h: Remove EXFUN.
9828 * xterm.h: Remove EXFUN.
9830 2012-07-03 Glenn Morris <rgm@gnu.org>
9832 * lisp.h (Frandom): Make it visible to C.
9833 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9834 buffer for invisible buffers. (Bug#1229)
9836 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9838 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9839 values which aren't power of 2.
9840 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9841 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9844 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9846 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9848 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9850 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9852 * alloc.c (allocate_vector_block): Remove redundant
9853 calls to mallopt if DOUG_LEA_MALLOC is defined.
9854 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9855 avoid calls to mallopt if zero_vector is returned.
9857 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9859 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9860 is enabled, avoid dereferencing NULL current_sblock if
9863 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9865 Cleanup basic buffer management.
9866 * buffer.h (struct buffer): Change layout to use generic vector
9867 marking code. Fix some comments. Change type of 'clip_changed'
9868 to bitfield. Remove unused #ifndef old.
9869 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9870 (GET_OVERLAYS_AT): Fix indentation.
9871 (for_each_per_buffer_object_at): New macro.
9872 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9873 (Fbuffer_local_variables): Use it.
9874 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9875 * alloc.c (allocate_buffer): Adjust to match new layout of
9876 struct buffer. Fix comment.
9877 (mark_overlay): New function.
9878 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9879 Lisp area of struct buffer.
9880 (mark_object): Use it. Adjust marking of misc objects
9881 and related comments.
9883 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9885 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9886 wrapper that is not needed because the wrapped code is a no-op (zero
9887 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9888 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9890 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9892 * alloc.c (mark_buffer): Simplify. Remove prototype.
9893 (mark_object): Add comment. Reorganize marking of vector-like
9894 objects. Use CHECK_LIVE for all vector-like objects except buffers
9895 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9896 Avoid redundant calls to mark_vectorlike for bool vectors.
9898 2012-06-30 Glenn Morris <rgm@gnu.org>
9900 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9902 * epaths.in (PATH_SITELOADSEARCH): New.
9903 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9904 This is rather than relying on --enable-locallisppath elements
9905 having "site-lisp" in their names. (Bug#10208#25, 11658)
9907 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9909 * w32proc.c (sys_select): Accept and ignore one more argument.
9911 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9913 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9914 (pselect) [!MS_DOS]: Redirect to sys_select.
9916 * sysdep.c: Don't include dos.h and dosfns.h.
9918 * process.c (sys_select):
9919 * msdos.c (sys_select): Accept one more argument and ignore it.
9921 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9922 adapt data types and code to that.
9925 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9926 which clashes with the gnulib function of the same name.
9928 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9930 * font.c (font_style_to_value, font_style_symbolic)
9931 (font_prop_validate_style): Add type checks for values in
9934 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9936 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9939 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9941 * xdisp.c (try_window_id): Undo last change.
9943 * w32.c (getwd): Adjust commentary about startup_dir.
9944 (init_environment): Always call sys_access, even in non-MSVC
9945 builds. Don't chdir to the directory of the Emacs executable.
9946 This undoes code from 1997 which was justified by the need to
9947 "avoid conflicts when removing and renaming directories". But its
9948 downside was that every relative file name was being interpreted
9949 relative to the directory of the Emacs executable, which can never
9950 be TRT. In particular, it broke sys_access when called with

10144 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10146 Use sprintf return value instead of invoking strlen on result.
10147 In the old days this wasn't portable, since some sprintf
10148 implementations returned char *. But they died out years ago and
10149 Emacs already assumes sprintf returns int.
10150 Similarly for float_to_string.
10151 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10159 Use sprintf or float_to_string result to avoid need to call strlen.
10160 * data.c (Fnumber_to_string):

10162 * lisp.h, print.c (float_to_string): Now returns int length.
10163 * term.c (produce_glyphless_glyph):
10164 Use sprintf result rather than recomputing it.
10166 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10174 strcasecmp if available.

10195 * xfns.c (x_window): Remove redundant cast.
10197 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10199 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10200 `const char *' to `char *' to avoid compiler warning.
10202 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10204 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10205 instead of truncating it to 63 (admittedly a generous limit).
10207 * process.c: Fix spelling and caps in comments.

10267 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10268 This improves on the previous patch, which introduced a bug
10269 when time_t is unsigned and as wide as intmax_t.
10270 See <http://bugs.gnu.org/9000#51>.
10272 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10301 language ID in the event parameters.
10303 * w32term.c (w32_read_socket): Put the new keyboard codepage into

10337 Support higher-resolution time stamps (Bug#9000).
10338 The time stamps are only nanosecond-resolution at the C level,
10339 since that's the best that any real-world system supports now.
10340 But they are picosecond-resolution at the Lisp level, as that's
10341 easy, and leaves room for future OS improvements.
10343 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10346 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10347 Don't get current time unless it's needed.
10349 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10350 now provides it if it's absent.
10351 (start_atimer): Port to higher-res time stamps.
10352 Check for time stamp overflow. Don't get current time more
10353 often than is needed.
10355 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10356 Include systime.h, not time.h.
10357 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10359 * dired.c: Include stat-time.h.
10360 (Ffile-attributes): File times now have higher resolution.
10362 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10363 (struct image): Timestamp now has higher resolution.
10365 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10366 has at least microseconds now. All uses removed.
10367 (update_frame, update_single_window, update_window, update_frame_1)
10368 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10369 (duration_to_sec_usec): Remove; no longer needed.
10371 * editfns.c (time_overflow): Now extern.
10372 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10373 (float-time, Fformat_time_string, Fcurrent_time_string)

10376 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10377 (decode_time_components, lisp_seconds_argument): New functions.
10378 (make_time): Now static.
10379 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10380 Report an error if the time is invalid, rather than having the caller
10383 * fileio.c: Include <stat-time.h>
10384 (Fcopy_file): Copy higher-resolution time stamps.
10385 Prefer to set the time stamp via a file descriptor if that works.
10386 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10387 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10388 (Fvisited_file_modtime, Fset_visited_file_modtime):
10389 Support higher-resolution time stamps.
10391 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10393 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10395 * image.c (prepare_image_for_display, clear_image_cache)
10396 (lookup_image): Port to higer-resolution time stamps.
10398 * keyboard.c (start_polling, bind_polling_period):
10399 Check for time stamp overflow.
10400 (read_char, kbd_buffer_get_event, timer_start_idle)
10401 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10402 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10403 Port to higher-resolution time stamps. Do not assume time_t is signed.
10404 (decode_timer): New function. Timers are now vectors of length 9,
10405 not 8, to accommodate the picosecond component.
10406 (timer_check_2): Use it.
10408 * nsterm.m (select_timeout, timeval_subtract): Remove.
10409 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10410 as they're a bit more accurate and handle overflow better.
10411 (ns_select): Change prototype to be compatible with pselect.
10412 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10413 * nsterm.h (ns_select): Adjust prototype.
10415 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10416 us-resolution time stamps.
10417 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10419 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10421 * lisp.h (time_overflow): New decl.
10422 (wait_reading_process_output): First arg is now intmax_t, not int,
10423 to accommodate larger waits.
10425 * process.h (struct Lisp_Process.read_output_delay):
10426 Now counts nanoseconds, not microseconds.
10427 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10429 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10430 (wait_reading_process_output):
10431 Port to ns-resolution time stamps.
10432 (Faccept_process_output, wait_reading_process_output):
10433 Check for time stamp overflow. Do not assume time_t is signed.
10434 (select_wrapper): Remove; we now use pselect.
10435 (Fprocess_attributes): Now generates ns-resolution time stamps.
10437 * sysdep.c: Include utimens.h. Don't include utime.h
10438 or worry about struct utimbuf; gnulib does that for us now.
10439 (gettimeofday): Remove; gnulib provides a substitute.
10440 (make_timeval): New function.
10441 (set_file_times): Now sets ns-resolution time stamps.
10442 New arg FD; all uses changed.
10443 (time_from_jiffies, ltime_from_jiffies, get_up_time)

10445 Now returns ns-resolution time stamp. All uses changed.
10446 Check for time stamp overflow.
10448 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10449 provides a substitute now.
10451 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10452 since it guarantees struct timespec.
10453 (EMACS_TIME): Now struct timespec, so that we can support
10454 ns-resolution time stamps.
10455 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10456 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10457 (EMACS_USECS): Remove.
10458 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10459 so multiply the arg by 1000 before storing it.

10469 (make_timeval, make_lisp_time, decode_time_components): New decls.
10470 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10471 that it mishandled time_t overflow. You can't compare by subtracting!
10472 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10473 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10475 * term.c: Include <sys/time.h>.
10476 (timeval_to_Time): New function, for proper overflow wraparound.
10477 (term_mouse_position, term_mouse_click): Use it.
10479 * undo.c (record_first_change): Support higher-resolution time stamps
10480 in the undo buffer.
10481 (Fprimitive_undo): Use them when restoring time stamps.
10483 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10484 (w32_get_internal_run_time):
10485 Port to higher-resolution Emacs time stamps.
10486 (ltime): Now accepts single 64-bit integer, as that's more convenient
10489 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10491 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10492 for compatibility with pselect. Support ns-resolution time stamps.
10494 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10496 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10497 Check for time stamp overflow, and support ns-resolution time stamps.
10499 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10500 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10501 (timeval_subtract): Remove; no longer needed.
10502 (XTflash, XTring_bell, x_wait_for_event):
10503 Port to ns-resolution time stamps. Don't assume time_t is signed.

10509 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10511 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10512 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10513 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10514 staticidx goes up to 1597 out of 1600 = 0x640.)
10516 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10518 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10519 Otherwise, the umask might be mistakenly 0 while handling input signals.
10521 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10523 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10529 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10530 access to `contents' member of Lisp_Vector objects with AREF and ASET
10533 2012-06-19 Chong Yidong <cyd@gnu.org>
10535 * frame.c (delete_frame): When selecting a frame on a different
10536 text terminal, do not alter the terminal's top-frame.

10539 frame's selected window and its terminal's top-frame.
10540 (unwind_format_mode_line): Restore them.
10541 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10543 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10544 since tty frames can be explicitly named.
10545 (prepare_menu_bars): Likewise.
10547 * term.c (Ftty_top_frame): New function.
10549 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10551 Port byte-code-meter to modern targets.
10552 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10553 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10554 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10555 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10556 (METER_1, METER_2): Simplify.
10558 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10560 * data.c (Fdefalias): Return `symbol' (bug#11686).
10562 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10564 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10565 gets killed during executing of this function (Bug#11665).
10566 Try to always return Qt when the buffer has been actually killed.
10567 (Vkill_buffer_query_functions): In doc-string say that functions
10568 run by this hook should not change the current buffer.
10570 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10572 Fix recently-introduced process.c problems found by static checking.
10573 * process.c (write_queue_push, write_queue_pop, send_process):

10592 * lisp.h (eassert): Assume C89 or later.
10593 This removes the need for CHECK.
10594 (CHECK): Remove. Its comments about always evaluating its
10595 argument were confusing, as 'eassert' typically does not evaluate
10598 * coding.c (produce_chars): Use ptrdiff_t, not int.
10600 * xterm.c (x_draw_underwave): Check for integer overflow.
10601 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10789 Use an inline function on all platforms when using the union type,

10876 * xdisp.c (vmessage): Treat frame message as multibyte.
10877 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10878 would generate the diagnostic "Making \302\247 buffer-local while

10883 * dispnew.c (showing_window_margins_p): Undo last change, which
10884 was done due to an inadvertent commit.

10905 Block-based vector allocation of small vectors.
10906 * lisp.h (struct vectorlike_header): New field `nbytes',
10907 adjust comment accordingly.
10908 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10909 to denote vector blocks. Adjust users (live_vector_p,
10910 mark_maybe_pointer, valid_lisp_object_p) accordingly.

10926 (init_alloc_once): Add call to init_vectors.
10928 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
10930 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
10932 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10934 * doprnt.c (doprnt): Truncate multibyte char correctly.
10935 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10936 would mishandle a string argument "Xc" if X was a multibyte
10937 character of length 2: it would truncate after X's first byte
10938 rather than including all of X.
10940 2012-06-06 Chong Yidong <cyd@gnu.org>
10942 * buffer.c (word_wrap): Doc fix.
10944 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10956 binary via PaX flags if the paxctl utility is available.
10957 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10958 Restore PaX flags to their default. (Bug#11398)
10960 2012-06-03 Chong Yidong <cyd@gnu.org>
10962 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte

10970 position is past the end of the mode line string.
10972 * buffer.c (buffer_local_value_1): New function, split from
10973 Fbuffer_local_value; can return Qunbound.
10974 (Fbuffer_local_value): Use it.
10975 (Vmode_line_format): Docstring tweaks.
10977 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10989 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10991 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10992 Convert pctcpu and pctmem to Lisp float properly.
10993 Let the compiler fold better, as 100.0/0x8000 is exact.
10995 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10997 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11000 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11004 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11006 For a 'struct window', replace some Lisp_Object fields to
11007 bitfields where appropriate, remove unused fields.
11008 * window.h (struct window): Remove unused 'last_mark_x' and
11009 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11010 change its type from Lisp_Object to bitfield.
11011 Change type of 'force_start', 'optional_new_start',
11012 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11013 fields from Lisp_Object to bitfield. Adjust users accordingly.
11015 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11017 Pacify gcc -Wdouble-precision when using Xaw.
11018 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11019 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11020 Use 'float' consistently, rather than 'float' in most places
11021 and 'double' in a couple of places.
11023 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11025 * xdisp.c (handle_stop): Detect whether we have overlay strings
11026 loaded by testing it->current.overlay_string_index to be
11027 non-negative, instead of checking whether n_overlay_strings is
11028 positive. (Bug#11587)
11030 2012-05-31 Chong Yidong <cyd@gnu.org>
11032 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11036 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11038 * search.c (search_buffer): Remove calls to
11039 r_alloc_inhibit_buffer_relocation, as it is now called by
11040 maybe_unify_char, which was the cause of relocation of buffer text
11043 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11045 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11046 for the duration of call to load_charset, to avoid problems with
11047 callers of maybe_unify_char that access buffer text through C
11050 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11051 decrement the inhibition flag, instead of just setting or
11054 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11056 Remove obsolete '#define static' cruft.
11057 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11058 This #undef was "temporary" in 2000; it is no longer needed
11059 now that '#define static' has gone away.
11060 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11061 (gray_bitmap_bits): Remove; no longer needed.
11062 All uses replaced with definiens.
11063 * xterm.c: Include "bitmaps/gray.xbm".
11065 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

11068 The following changes affect the code only when profiling.
11069 * dispnew.c (__executable_start): Rename from safe_bcopy.
11070 Define only on platforms that need it.
11071 * emacs.c: Include <sys/gmon.h> when profiling.
11072 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11073 (__executable_start): Remove decl, since lisp.h does it now.
11074 (safe_bcopy): Remove decl; no longer has that name.
11075 (main): Coalesce #if into single bit of code, for simplicity.
11076 Cast pointers to uintptr_t, since standard libraries want integers
11078 * lisp.h (__executable_start): New decl.
11080 2012-05-31 Glenn Morris <rgm@gnu.org>
11082 * image.c (Fimagemagick_types): Doc fix.

11103 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11105 Do not create empty overlays with the evaporate property (Bug#9642).
11106 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11107 Bug#9642, but explicitly check that the buffer the overlay would
11108 be moved to is live and rearrange lines to make sure that errors
11109 will not put the overlay in an inconsistent state.
11110 (Fdelete_overlay): Cosmetics.
11112 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11114 * w32term.c (my_bring_window_to_top): New function.
11115 (x_raise_frame): Use handle returned by DeferWindowPos, which
11116 could be different from the original one.

11126 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11128 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11129 This avoids undefined behavior that might cause the eassert
11130 to not catch an out-of-range value.
11132 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11134 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11135 Update dependencies.
11137 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11139 * bidi.c (bidi_mirror_char): Fix last change.
11141 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11146 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11148 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11149 Only r_alloc_inhibit_buffer_relocation needed to be added;
11150 the others were already declared.
11152 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11153 before checking whether it's out of range. Put the check inside
11155 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11157 2012-05-27 Ken Brown <kbrown@cornell.edu>
11159 * callproc.c (Fcall_process): Restore a line that was accidentally
11160 commented out in the 2011-02-13 change (bug#11547).
11162 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11164 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11165 defined on ralloc.c.
11167 * buffer.c [REL_ALLOC]: Remove prototypes of
11168 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11169 they are now on lisp.h.
11171 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11173 * search.c (search_buffer): Use it to inhibit relocation of buffer
11174 text while re_search_2 is doing its job, because re_search_2 is
11175 passed C pointers to buffer text. (Bug#11519)
11177 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11178 Update value to 24.
11180 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11181 state after an additional call to move_it_in_display_line_to, keep
11182 the values of it->max_ascent and it->max_descent found for the
11184 (pos_visible_p): Revert the comparison against bottom_y to what it
11185 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11188 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11190 Fix coding-related core dumps with gcc -ftrapv.
11191 The code was computing A - B, where A and B are pointers, and B is
11192 random garbage. This can lead to core dumps on platforms that
11193 have special pointer registers, and it also leads to core dumps on
11194 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11195 A - B only when B is initialized properly.
11196 * coding.c (coding_set_source, coding_set_destination): Return void.
11197 (coding_change_source, coding_change_destinations): New functions,
11198 with the old behaviors of coding_set_source and coding_set_destination.
11199 All callers that need an offset changed to use these new functions.
11201 2012-05-26 Glenn Morris <rgm@gnu.org>
11203 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

11209 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11211 * w32console.c: Include window.h.
11212 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11214 (initialize_w32_display): Initialize mouse-highlight data.
11216 * w32inevt.c: Include termchar.h and window.h.
11217 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11218 moves, call note_mouse_highlight. If help_echo changed, call
11219 gen_help_event to produce help-echo message in the echo area.
11220 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11223 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11225 * lread.c (read1): Simplify slightly to avoid an overflow warning
11226 with GCC 4.7.0 on x86-64.
11228 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11230 * bidi.c (bidi_mirror_char): Revert last change: an int is
11231 definitely wide enough here.

11243 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11245 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11247 Use int, not EMACS_INT, where int is wide enough.
11248 (inhibit_garbage_collection, Fgarbage_collect):
11249 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11250 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11251 int might not be wide enough.
11252 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11253 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11254 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11255 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11256 (bidi_level_of_next_char, bidi_move_to_visually_next):
11257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11258 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11259 (Fkill_buffer, Fset_buffer_major_mode)
11260 (advance_to_char_boundary, Fbuffer_swap_text)

11262 (overlay_touches_p, struct sortvec, record_overlay_string)
11263 (overlay_strings, recenter_overlay_lists)

11269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11270 (validate_region): Omit unnecessary test for b <= e,
11271 since that's guaranteed by the previous test.
11272 (adjust_overlays_for_delete): Avoid pos + length overflow.
11273 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11274 (report_overlay_modification):
11275 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11276 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11277 Omit pointer cast, which isn't needed anyway, and doesn't work
11278 after the EMACS_INT -> ptrdiff_t change.
11279 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11280 * buffer.h: Adjust decls to match defn changes elsewhere.
11281 (struct buffer_text, struct buffer):
11282 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11283 Use EMACS_INT, not int, where int might not be wide enough.
11284 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11285 not int, to avoid needless 32-bit limit on 64-bit hosts.
11286 (exec_byte_code): Use tighter memory-full test, one that checks
11287 for alloca overflow. Don't compute the address of the object just
11288 before an array, as that's not portable. Use EMACS_INT, not
11289 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11290 * callint.c (Fcall_interactively):
11291 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11292 * callproc.c (call_process_kill, Fcall_process):

11302 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11303 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11304 (casify_object): Avoid integer overflow when overallocating buffer.
11305 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11306 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11307 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11308 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11309 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11310 integers are now checked earlier. All uses replaced with XINT.
11312 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11313 For CCL_MapSingle, check that content and value are in int range.
11314 (ccl_driver, Fregister_code_conversion_map):
11315 Check that Vcode_version_map_vector is a vector.
11316 (resolve_symbol_ccl_program): Check that vector header is in range.
11317 Always copy the vector, so that we can check its contents reliably
11318 now rather than having to recheck each instruction as it's being
11319 executed. Check that vector words fit in 'int'.
11320 (ccl_get_compiled_code, Fregister_ccl_program)
11321 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11322 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11323 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11324 contents are in range.
11325 (Fccl_execute_on_string): Check that status is in range.

11327 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11328 Accept and return EMACS_INT, not int, because callers can pass values

11335 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11336 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11337 avoid mishandling large integers.

11347 (Fdefine_charset_internal): Check ranges here, more carefully.
11348 Don't rely on undefined behavior with signed left shift overflow.
11349 Don't assume unsigned int fits into fixnum, or that fixnum fits
11350 into unsigned int. Don't require max_code to be a valid fixnum;
11351 that's not true for gb10830 4-byte on a 32-bit host. Allow
11352 invalid_code to be a cons, for the same reason. Require code_offset
11353 to be a character. Avoid int overflow if max_char is close
11355 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11356 this is intended anyway and avoids some undefined behavior.
11357 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11358 INDEX_TO_CODE_POINT, as that's what it expects.
11359 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11360 * charset.h (DECODE_CHAR): Return int, not unsigned;
11361 this is what was intended anyway, and it avoids undefined behavior.
11362 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11363 integer-overflow issues.
11364 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11365 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11366 where the argument is EMACS_INT, and this behavior is not intended.
11367 * chartab.c (Fmake_char_table, Fset_char_table_range)
11368 (uniprop_get_decoder, uniprop_get_encoder):
11369 Don't assume fixnum fits in int.
11370 * cmds.c (move_point): New function, that does the gist of
11371 Fforward_char and Fbackward_char, but does so while checking
11372 for integer overflow more accurately.
11373 (Fforward_char, Fbackward_char): Use it.
11374 (Fforward_line, Fend_of_line, internal_self_insert)
11375 (internal_self_insert):
11376 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11978 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
11979 (handle_tool_bar_click):
11980 Use int, not unsigned, since we prefer signed and the signedness
11981 doesn't matter here.
11982 (get_next_display_element, next_element_from_display_vector):
11983 Use int, not EMACS_INT, when int is wide enough.
11984 (start_hourglass): Use duration_to_sec_usec to do proper
11985 overflow checking on durations.
11986 * xfaces.c (Fbitmap_spec_p):
11987 Check that fixnums are in proper range for system types.
11988 (compare_fonts_by_sort_order):
11989 Avoid mishandling comparisons due to subtraction overflow.

12017 (x_get_local_selection, x_reply_selection_request)
12018 (x_handle_selection_request, wait_for_property_change):
12019 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12020 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12021 short is wide enough.
12022 (x_send_client_event): Don't assume fixnum fits in int.
12023 * xterm.c (x_x_to_emacs_modifiers):
12024 Don't assume EMACS_INT overflows nicely into int.
12025 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12026 may come from Lisp.
12027 (handle_one_xevent): NATNUMP can eval its arg twice.
12028 (x_connection_closed):
12029 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12030 * xterm.h: Adjust decls to match defn changes elsewhere.
12031 (struct scroll_bar): Use struct vectorlike_header
12032 rather than rolling our own approximation.

12035 2012-05-25 Glenn Morris <rgm@gnu.org>
12037 * lisp.mk (lisp): Update for more files being compiled now.
12039 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12041 * lread.c: Remove `read_pure' which makes no difference.
12042 (read_pure): Remove var.
12043 (unreadpure): Remove function.
12044 (readevalloop): Don't call read_list with -1 flag.
12045 (read1, read_vector): Don't test read_pure any more.
12046 (read_list): Simplify.
12048 * fileio.c, character.h: Minor style tweaks.
12050 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12052 * window.h (clip_changed): Remove useless declaration.
12054 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12056 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12057 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12059 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12062 This directory predates autoconf and is no longer needed nowadays.
12063 Move its few remaining bits of functionality to where they're needed.
12064 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12065 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12066 * m/template.h: Remove.
12067 * Makefile.in (M_FILE): Remove. All uses removed.
12068 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12069 * lisp.h (USE_LSB_TAG):
12070 * mem-limits.h (EXCEEDS_LISP_PTR):
12071 Use VAL_MAX, not VALBITS, in #if.
12072 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12073 (EMACS_UINT): Define unconditionally now.
12074 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12075 (BITS_PER_EMACS_INT): New constants, replacing
12076 what used to be in config.h, but not useful in #if.
12077 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12078 define them any more.
12079 (VAL_MAX): New macro.
12081 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12082 BITS_PER_EMACS_INT, in #if.
12083 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12084 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12085 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12086 * s/ms-w32.h (DATA_START):
12087 Move here from removed file m/intel386.h.
12088 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12089 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12091 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12093 Assume C89 or later.
12094 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12095 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12097 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

12103 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12104 * xterm.c (input_signal_count): Assume volatile works.
12106 2012-05-21 Ken Brown <kbrown@cornell.edu>
12108 * xgselect.c (xg_select): Fix first argument in call to 'select'
12111 2012-05-20 Ken Brown <kbrown@cornell.edu>
12113 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12114 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12116 2012-05-19 Ken Brown <kbrown@cornell.edu>
12118 * xfns.c (x_in_use): Remove `static' qualifier.
12119 * xterm.h (x_in_use): Declare.
12120 * xgselect.c: Include xterm.h.
12121 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12122 and `display_arg' (bug#9754).
12124 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12126 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12128 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12129 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12131 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12133 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12135 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12136 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12138 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12139 reference to image_cache->refcount.
12140 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12142 2012-05-17 Juri Linkov <juri@jurta.org>
12144 * search.c (Fword_search_regexp, Fword_search_backward)
12145 (Fword_search_forward, Fword_search_backward_lax)
12146 (Fword_search_forward_lax): Move functions to isearch.el
12147 (bug#10145, bug#11381).
12149 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12151 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12153 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12155 * lread.c (init_obarray): Declare Qt and Qnil as special.
12157 2012-05-14 Glenn Morris <rgm@gnu.org>
12159 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12160 Put "libexec" before "bin", for the sake of init_callproc_1.
12162 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12164 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12166 * unexaix.c: Port to more-recent AIX compilers.
12167 (report_error, report_error_1, make_hdr, copy_sym)
12168 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12169 Make arguments const char *, not char *, to avoid violations of C
12170 standard and to fix some AIX warnings reported by Gilles Pion.
12172 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12174 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12175 already have overlays loaded.
12176 (handle_single_display_spec): Before returning without displaying
12177 fringe bitmap, synchronize the bidi iterator with the main display
12178 iterator, by calling iterate_out_of_display_property.
12179 (iterate_out_of_display_property): Detect buffer iteration by
12180 testing that it->string is a Lisp string.
12181 (get_next_display_element): When the current object is exhausted,
12182 and there's something on it->stack, call set_iterator_to_next to
12183 proceed with what's on the stack, instead of returning zero.
12184 (set_iterator_to_next): If called at the end of a Lisp string,
12185 proceed to consider_string_end without incrementing string
12186 position. Don't increment display vector index past the end of
12187 the display vector. (Bug#11417)
12188 (pos_visible_p): Don't report a position visible when move_it_to
12189 stopped at the last line of window, which happens to be scanned
12190 backwards by the bidi iteration. (Bug#11464)
12192 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12194 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12195 and right-margin display specs even if the spec is invalid or we
12196 are on a TTY, and thus unable to display on the fringes.
12197 That's because the text with the property will not be displayed anyway,
12198 so we need to signal to the caller that this is a "replacing"
12199 display spec. This fixes display when the spec is invalid or we
12202 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12204 * unexaix.c (make_hdr): Fix typo in prototype.
12205 This bug broke the build on AIX. Problem reported by Gilles Pion.
12207 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12209 * keyboard.c (kbd_buffer_get_event): Read special events also in
12210 batch mode. (Bug#11415)
12212 2012-05-12 Glenn Morris <rgm@gnu.org>
12214 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12216 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12218 * lisp.mk (lisp): Add newcomment.elc.
12220 2012-05-12 Glenn Morris <rgm@gnu.org>
12222 * Makefile.in (MKDIR_P): New, set by configure.
12223 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12225 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12227 Remove unused function hourglass_started.
12228 * dispextern.h (hourglass_started):
12229 * w32fns.c (hourglass_started):
12230 * xdisp.c (hourglass_started): Remove.
12232 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12234 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12235 Update dependencies.
12237 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12239 * xgselect.c (xg_select): Put maxfds+1 into a var.
12240 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12242 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12244 2012-05-10 Dave Abrahams <dave@boostpro.com>
12246 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12247 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12249 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12251 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12252 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12253 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12254 Initialize xd_registered_buses.
12256 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12258 Untag more efficiently if USE_LSB_TAG.
12259 This is based on a proposal by YAMAMOTO Mitsuharu in
12260 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12261 For an admittedly artificial (nth 8000 longlist) benchmark on
12262 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12263 Emacs's overall text size by 1%.
12264 * lisp.h (XUNTAG): New macro.
12265 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12266 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12267 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12268 * eval.c (Fautoload):
12269 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12270 * frame.h (XFRAME): Use XUNTAG.
12272 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12273 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12274 Remove unportable assumptions about print widths of types like
12276 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12277 intptr_t when converting between pointer and integer, to avoid GCC
12278 warnings about wrong width.
12280 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12282 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12283 stack for each reader_thread, instead of defaulting to 8MB
12284 determined by the linker. This avoids failures in creating
12285 subprocesses on Windows 7, see the discussion in this thread:
12286 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12288 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12290 Fix up display of the *Minibuf-0* buffer in the mini window.
12291 * keyboard.c (read_char): Don't clear the echo area if there's no
12293 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12294 contents of *Minibuf-0*) if there's no message displayed in its stead.
12296 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12298 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12301 2012-05-06 Chong Yidong <cyd@gnu.org>
12303 * lisp.mk (lisp): Update.
12305 2012-05-05 Jim Meyering <meyering@redhat.com>
12307 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12309 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12311 * data.c (PUT_ERROR): New macro.
12312 (syms_of_data): Use it. Add new error type `user-error'.
12313 * undo.c (user_error): New function.
12314 (Fprimitive_undo): Use it.
12315 * print.c (print_error_message): Adjust print style for `user-error'.
12316 * keyboard.c (user_error): New function.
12317 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12319 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12321 Do not limit current-time-string to years 1000..9999.
12322 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12323 (Fcurrent_time_string): Support any year that is supported by the
12324 underlying localtime representation. Don't use asctime, as it
12325 has undefined behavior for years outside the range -999..9999.
12327 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12329 Fix race conditions involving setenv, gmtime, localtime, asctime.
12330 Without this fix, interrupts could mess up code that uses these
12331 nonreentrant functions, since setting TZ invalidates existing
12332 tm_zone or tzname values, and since most of these functions return
12333 pointers to static storage.
12334 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12335 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12336 Grow the critical sections to include not just invoking
12337 localtime/gmtime, but also accessing these functions' results
12338 including their tm_zone values if any, and any related TZ setting.
12339 (format_time_string): Last arg is now struct tm *, not struct tm **,
12340 so that the struct tm is saved in the critical section.
12341 All callers changed. Simplify allocation of initial buffer, partly
12342 motivated by the fact that memory allocation needs to be outside
12343 the critical section.
12345 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12347 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12348 with RESET_INTERVAL.
12350 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12351 Remove duplicated buffer name initialization.
12353 2012-05-02 Jim Meyering <jim@meyering.net>
12355 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12357 * xfns.c (x_window): Use xstrdup (Bug#11375).
12359 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12361 * xdisp.c (pos_visible_p): If already at a newline from the
12362 display string before the 'while' loop, don't walk back the glyphs
12363 from it3.glyph_row. Solves assertion violation when the display
12364 string begins with a newline (egg.el). (Bug#11367)
12366 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12368 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12371 2012-05-01 Glenn Morris <rgm@gnu.org>
12373 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12374 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12375 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12376 All were removed before 23.1.
12378 * dispnew.c: Remove HAVE_LIBNCURSES test;
12379 it is always true on relevant platforms.
12381 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12382 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12384 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12386 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12388 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12389 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):

12394 Do not avoid creating empty evaporating overlays (Bug#9642).
12395 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12396 That is, do not delete an evaporating overlay if it becomes
12397 empty after its bounds are adjusted to fit within its buffer.
12398 This fix caused other problems, and I'm reverting it until we get
12399 to the bottom of them.
12401 2012-04-27 Chong Yidong <cyd@gnu.org>
12403 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12405 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12407 * xdisp.c (pos_visible_p): If the window start position is beyond
12408 ZV, start the display from buffer beginning. Prevents assertion
12409 violation in init_iterator when the minibuffer window is scrolled
12410 via the scroll bar.
12412 * window.c (window_scroll_pixel_based): Likewise.
12414 2012-04-27 Chong Yidong <cyd@gnu.org>

12418 2012-04-27 Glenn Morris <rgm@gnu.org>
12420 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12421 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12423 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12425 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12426 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12428 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12430 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12431 display element, check also the underlying string or buffer
12432 character. (Bug#11341)
12434 * w32menu.c: Include w32heap.h.
12435 (add_menu_item): If the call to AppendMenuW (via
12436 unicode_append_menu) fails, disable Unicode menus only if we are
12437 running on Windows 9X/Me.
12439 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12441 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12442 (xgetint): Add missing shift for LSB tags.
12444 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12446 * keyboard.c (read_char): Don't wipe echo area for select window

12452 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12453 manipulation of :loaded-from data.
12455 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12457 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12458 now a cons (bug#11311).
12460 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12462 Do not create empty overlays with the evaporate property (Bug#9642).
12463 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12464 if it becomes empty after its bounds are adjusted to fit within
12465 its buffer. Without this fix, in a nonempty buffer (let ((o
12466 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12467 yields an empty overlay that has the evaporate property, which is
12468 not supposed to happen.

12491 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12492 (__malloc_size_t, __malloc_ptrdiff_t):
12493 Remove. All uses removed, replaced by the definiens if needed,
12494 since we can assume C89 or better now.

12513 (valloc): Use getpagesize, not __getpagesize.
12514 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

12583 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12585 * sysdep.c [__FreeBSD__]: Minor cleanups.
12586 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12587 Use Emacs indenting style more consistently. Avoid some casts.
12588 Use 'double' consistently rather than mixing 'float' and 'double'.
12590 2012-04-21 Eduard Wiebe <usenet@pusto.de>
12592 * sysdep.c (list_system_processes, system_process_attributes):
12593 Add implementation for FreeBSD (Bug#5243).

12599 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12601 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12602 It is never used otherwise.
12604 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12606 * print.c (print_preprocess): Only check print_depth if print-circle
12608 (print_object): Check for cycles even when print-circle is nil and

12613 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12614 set the status to "failed" and ensure that sentinel is run.
12616 2012-04-20 Glenn Morris <rgm@gnu.org>
12618 * process.c (Fset_process_inherit_coding_system_flag)

12669 New extern decls, to avoid calling undeclared functions.
12670 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12671 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12672 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12673 (NEED_MEM_INSERT): New macro.
12674 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12675 Remove one incorrect comment and fix another.

12711 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12712 * s/netbsd.h, s/sol2-6.h:
12713 Remove definition of GC_MARK_STACK, since the default now works.
12714 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12717 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12719 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12721 * lread.c (lisp_file_lexically_bound_p):

12742 2012-04-11 Daniel Colascione <dancol@dancol.org>
12744 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12745 against is gone. It's better to use vfork now so that when Cygwin
12746 gains a new, working vfork, we use it automatically (bug#10398).
12748 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12769 being loaded (bug#10424).
12771 2012-04-09 Glenn Morris <rgm@gnu.org>
12773 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12774 not just in the obarray, before snarfing them. (Bug#11036)

12786 Add convenience `GNUTLS_LOG2i' macro.
12788 * gnutls.c (gnutls_log_function2i): Convenience log function.
12789 (emacs_gnutls_read): Use new log functions,
12790 `gnutls_handshakes_tried' process member, and
12791 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12792 attempts per process (connection).
12794 2012-04-09 Chong Yidong <cyd@gnu.org>
12796 * eval.c (Fuser_variable_p, user_variable_p_eh)
12797 (lisp_indirect_variable): Functions deleted.
12798 (Fdefvar): Caller changed.
12800 * callint.c (Finteractive, Fcall_interactively):
12801 * minibuf.c (Fread_variable): Callers changed.
12803 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12805 * xdisp.c (set_cursor_from_row): If the display string appears in
12806 the buffer at position that is closer to point than the position
12807 after the display string, display the cursor on the first glyph of
12808 the display string. Fixes cursor display when a 'display' text
12809 property immediately follows invisible text. (Bug#11094)
12811 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12813 composite.c: use 'double' consistently
12814 * composite.c (get_composition_id): Use 'double' consistently
12815 instead of converting 'float' to 'double' and vice versa; this is
12816 easier to understand and avoids a GCC warning.
12818 2012-04-09 Glenn Morris <rgm@gnu.org>
12820 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12821 preparation for dumping it with emacs. (Bug#4789)

12843 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12844 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12845 objects, as mark_maybe_pointer will catch them otherwise.
12846 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12847 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12865 [!WINDOWSNT]: New macros.
12866 (init_libxml2_functions, libxml2_loaded_p): New functions.
12867 (parse_region): Call fn_xmlCheckVersion instead of using the macro

12869 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12870 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12872 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12873 Call init_libxml2_functions before calling libxml2 functions.
12874 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12876 * emacs.c: Don't include libxml/parser.h.
12877 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12878 xmlCleanupParser directly.
12880 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12882 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12884 * indent.c (Fvertical_motion): If there is a display string at
12885 point, use it.vpos to compute how many lines to backtrack after

12888 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12890 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12891 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12892 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12893 macros related to unification of CJK characters. For the details,
12894 see the discussion following the message here:
12895 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12897 2012-04-04 Chong Yidong <cyd@gnu.org>
12899 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12901 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12903 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12904 instead of alloca. (Bug#11138)
12906 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

12911 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12913 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12914 position we get to after a call to move_it_to fails the
12915 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12916 only if we wind up in a string from display property. (Bug#11063)
12918 * window.c (Fdelete_other_windows_internal): Invalidate the row
12919 and column information about mouse highlight, so that redisplay
12920 restores it after reallocating the glyph matrices. (Bug#7464)
12922 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12923 string comes from a `display' text property, use the buffer
12924 position of that property as if we actually saw that position in
12926 (move_it_by_lines): Remove the assertion that
12927 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12928 violated when there's a before-string at the beginning of a line.
12931 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12933 * xdisp.c (append_space_for_newline): If the default face was
12934 remapped, use the remapped face for the appended newline.
12935 (extend_face_to_end_of_line): Use the remapped default face for
12936 extending the face to the end of the line.
12937 (display_line): Call extend_face_to_end_of_line when the default
12938 face was remapped. (Bug#11068)
12940 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12942 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

12966 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12968 2012-03-25 Kenichi Handa <handa@m17n.org>
12970 * dispextern.h (struct glyph): Change the bit length of
12971 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12973 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12975 * s/ms-w32.h (tzname): Include time.h before redirecting to
12976 _tzname. Fixes the MSVC build. (Bug#9960)
12978 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12980 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12983 * xterm.c (XTread_socket): Only modify handling_signal if
12984 !SYNC_INPUT. (Bug#11080)
12986 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12988 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12989 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12990 when fetching a multibyte character consumes more bytes than
12991 CHAR_BYTES returns, due to unification of CJK characters in
12992 string_char. (Bug#11073)
12994 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12996 * process.c (wait_reading_process_output): Handle pty disconnect
12997 by refraining from sending oneself a SIGCHLD (bug#10933).

13020 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13021 to reflect default non-nil value of redisplay-dont-pause.
13023 2012-03-19 Kenichi Handa <handa@m17n.org>
13025 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13026 it fit in a valid range (Bug#11003).
13028 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13030 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13031 that is not from display property, accept the row as a "cursor
13032 row" if one of the string's character has a non-nil `cursor'
13033 property. Fixes cursor positioning when there are newlines in
13034 overlay strings, e.g. in icomplete.el. (Bug#11035)
13036 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13038 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13040 2012-03-12 Chong Yidong <cyd@gnu.org>
13042 * eval.c (inhibit_lisp_code): Rename from
13043 inhibit_window_configuration_change_hook; move from window.c.
13045 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13046 * window.c (run_window_configuration_change_hook)
13047 (syms_of_window): Callers changed.

13067 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13070 2012-03-03 Glenn Morris <rgm@gnu.org>
13072 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13074 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13076 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13077 position past the first glyph_row that ends at ZV. (Bug#10902)
13078 (redisplay_window, next_element_from_string): Fix typos in
13080 (redisplay_window): Pass to move_it_vertically the margin in
13081 pixels, not in screen lines.
13083 2012-03-02 Glenn Morris <rgm@gnu.org>
13085 * buffer.c (buffer-list-update-hook): Doc fix.
13087 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13089 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13090 push_it before setting up the iterator for the first overlay
13091 string, even if we have an empty string loaded.
13092 (next_overlay_string): If there's an empty string on the iterator
13093 stack, pop the stack. (Bug#10903)
13095 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13097 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13098 Suggested by Stefan Monnier in
13099 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13100 * alloc.c (widen_to_Lisp_Object): New static function.
13101 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13102 and widening them to Lisp_Objects. This would work even if
13103 USE_LSB_TAG is defined and wide integers are used, which might
13104 happen in a future version of Emacs.
13106 2012-02-25 Chong Yidong <cyd@gnu.org>
13108 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13111 * xselect.c (Fx_selection_exists_p): Doc fix.

13113 before saving to clipboard manager.
13115 2012-02-24 Chong Yidong <cyd@gnu.org>
13117 * keyboard.c (process_special_events): Handle all X selection
13118 requests in kbd_buffer, not just the next one (Bug#8869).
13120 2012-02-23 Chong Yidong <cyd@gnu.org>
13122 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13123 call when setting menu-bar-lines and tool-bar-lines parameters.
13124 (unwind_create_frame_1): New helper function.

13145 when computing $valmask.
13147 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13148 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13149 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13150 It's useless in that case, and it can cause problems on hosts
13151 that allocate halves of EMACS_INT values separately.
13152 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13153 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13154 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13155 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13156 it avoids undefined behavior on hosts where shifting right by more
13157 than the word width has undefined behavior.
13159 2012-02-19 Chong Yidong <cyd@gnu.org>
13161 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13162 (Funhandled_file_name_directory, Ffile_name_as_directory)

13181 2012-02-15 Chong Yidong <cyd@gnu.org>
13183 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

13199 2012-02-12 Chong Yidong <cyd@gnu.org>
13201 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13202 as that creates a dangerous corner case.
13204 * window.c (Fdelete_window_internal): Invalidate the mouse
13205 highlight (Bug#9904).
13207 2012-02-12 Glenn Morris <rgm@gnu.org>

13210 (Fx_get_selection_internal, Fx_disown_selection_internal)
13211 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13212 * nsselect.m (Fx_own_selection_internal)
13213 (Fx_disown_selection_internal, Fx_selection_exists_p)
13214 (Fx_selection_owner_p, Fx_get_selection_internal):
13215 Sync docs and argument specs with the xselect.c versions.
13217 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13219 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

13239 * buffer.c (Fbuffer_local_variables)
13240 (buffer_lisp_local_variables): Handle unbound vars correctly;
13241 don't let Qunbound leak into Lisp.
13243 2012-02-07 Glenn Morris <rgm@gnu.org>
13245 * image.c (Fimagemagick_types): Doc fix.
13247 * image.c (imagemagick-render-type): Change it from a lisp object
13248 to an integer. Move the doc here from the lisp manual.

13277 * keyboard.c (adjust_point_for_property): Don't position point
13278 before BEGV. (Bug#10696)
13280 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13282 Handle overflow when computing char display width (Bug#9496).
13283 * character.c (char_width): Return EMACS_INT, not int.
13284 (char_width, c_string_width): Check for overflow when
13285 computing the width; this is possible now that individual
13286 characters can have unbounded width. Problem introduced
13287 by merge from Emacs 23 on 2012-01-19.
13289 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13822 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13823 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13824 this macro definition.
13826 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
13829 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

13851 * xdisp.c (redisplay_window): If cursor row is not fully visible
13852 after recentering, and scroll-conservatively is set to a large
13853 number, scroll window by a few more lines to make the cursor fully
13854 visible and out of scroll-margin. (Bug#10105)
13855 (start_display): Don't move to the next line if the display should
13856 start at a newline that is part of a display vector or an overlay
13857 string. (Bug#10119)

13936 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13937 Otherwise, valgrind does not work on some platforms.
13938 Problem reported by Andreas Schwab in
13939 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13940 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13941 is set, removing the need for VIRT_ADDRESS_VARIES.
13942 (PURE_P): Use a more-efficient implementation that needs just one
13943 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13944 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13945 to 4 (xorl, subq, cmpq, setbe).
13946 * alloc.c (pure): Always extern now, since that's the
13947 VIRT_ADDR_VARIES behavior.
13948 (PURE_POINTER_P): Use a single comparison, not two, for
13949 consistency with the new puresize.h.
13950 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13951 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13952 Remove VIRT_ADDR_VARIES no longer needed.

13957 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13958 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13959 behave as if the cursor position were at the window margin.
13961 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13962 and the cursor position is out of bounds, behave as if the cursor
13963 position were at the window margin. (Bug#10075)
13965 2011-11-18 Chong Yidong <cyd@gnu.org>
13967 * window.c (Fwindow_combination_limit): Make first argument
13968 non-optional, since it is meaningless for live windows like the

13982 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
13983 hash values of the two rows.
13984 (copy_row_except_pointers): Preserve the used[] arrays and the
13985 hash values of the two rows. (Bug#10035)
13986 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13988 * xdisp.c (row_hash): New function, body extracted from
13989 compute_line_metrics.
13990 (compute_line_metrics): Call row_hash, instead of computing the
13993 * dispnew.c (verify_row_hash): Call row_hash for computing the
13994 hash code of a row, instead of duplicating code from xdisp.c.
13996 * dispextern.h (row_hash): Add prototype.
13998 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14000 * frame.c (delete_frame): Don't delete the terminal when the last

14023 (Fset_window_nest): Rename to Fset_window_combination_limit.
14024 (Vwindow_nest): Rename to Vwindow_combination_limit.
14025 (recombine_windows, make_parent_window, make_window)
14026 (Fsplit_window_internal, saved_window)
14027 (Fset_window_configuration, save_window_save): Rename all
14028 occurrences of window_nest to window_combination_limit.
14030 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
14032 * image.c (imagemagick_load_image): Fix typo.
14034 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14036 * xdisp.c (display_line): Move the call to
14037 highlight_trailing_whitespace before the call to
14038 compute_line_metrics, since the latter needs to see the final
14039 faces of all the glyphs to compute ROW's hash value.
14040 Fixes assertion violations in row_equal_p. (Bug#10035)
14042 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14044 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14045 just return (bug#10044).
14047 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14049 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14050 with user-defined heap size. Bump the default size of the temacs
14051 heap to 27MB, to avoid memory warning when running temacs.
14052 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
14054 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14055 current_matrix and desired_matrix. (Bug#9990)
14056 (verify_row_hash) [XASSERTS]: New function.
14057 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
14058 that the hash value of glyph rows is correct.

14090 avoid a crash (bug#9496).
14092 2011-11-09 Chong Yidong <cyd@gnu.org>
14094 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

14101 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14103 Avoid some portability problems by eschewing 'extern inline' functions.
14104 The trivial performance wins aren't worth the portability hassles; see
14105 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14107 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14108 (window_box_width, window_box_left, window_box_left_offset)
14109 (window_box_right, window_box_right_offset): Undo previous change,
14110 by removing the "extern"s.
14111 * intervals.c (adjust_intervals_for_insertion)
14112 (adjust_intervals_for_deletion): Undo previous change,
14113 making these static again.
14114 (offset_intervals, temp_set_point_both, temp_set_point)
14115 (copy_intervals_to_string): No longer inline.
14116 * xdisp.c (window_text_bottom_y, window_box_width)

14155 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14156 This is also needed for porting to any host where GC_MARK_STACK is
14157 not GC_MAKE_GCPROS_NOOPS.
14158 (which_symbols): Use it.
14160 2011-11-07 Kenichi Handa <handa@m17n.org>
14162 * coding.c (coding_set_destination): Check coding->src_pos only
14163 when coding->src_object is a buffer (bug#9910).

14173 * xmenu.c (cleanup_widget_value_tree): New function.
14174 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14175 calling free_menubar_widget_value_tree directly (Bug#9830).
14177 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14179 Fix some portability problems with 'inline'.
14180 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14181 (window_box_width, window_box_left, window_box_left_offset)
14182 (window_box_right, window_box_right_offset): Declare extern.
14183 Otherwise, these inline functions do not conform to C99 and
14184 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14185 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14186 * intervals.c (adjust_intervals_for_insertion)
14187 (adjust_intervals_for_deletion): Now extern, because otherwise the
14188 extern inline functions 'offset_intervals' couldn't refer to it.
14189 (static_offset_intervals): Remove.
14190 (offset_intervals): Rewrite using the old contents of
14191 static_offset_intervals. The old version didn't conform to C99
14192 because an extern inline function contained a reference to an
14193 identifier with static linkage.

14214 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
14215 (Fwindow_vscroll): Doc fix.
14216 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14217 argument, since it makes no sense to pass a live window and for
14218 consistency with window-child.

14339 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14340 past the beginning of the current glyph matrix.
14342 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14344 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14345 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

14388 2011-10-29 Glenn Morris <rgm@gnu.org>
14390 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14391 Not clear what it was for, and it causes various bugs. (Bug#9839)
14393 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14395 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14396 possible random value that matches one of those tested as
14397 condition to clear the mouse face.
14399 2011-10-28 Chong Yidong <cyd@gnu.org>

14415 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14417 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14418 <oslsachem@gmail.com> for helping to debug this.
14420 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

14426 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14428 (w32font_open_internal, compute_metrics):
14429 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14430 instead of calling the "wide" APIs directly.
14432 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14434 * w32.h (syms_of_w32font): Add prototype.
14436 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14438 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14439 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14440 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14441 (Fmove_to_window_line): Doc fix.
14443 2011-10-27 Chong Yidong <cyd@gnu.org>
14445 * process.c (make_process): Set gnutls_state to NULL.
14447 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14448 non-NULL, regardless of GNUTLS_INITSTAGE.
14449 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14450 an error. Set process slots as soon as we allocate them.
14452 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14454 2011-10-27 Chong Yidong <cyd@gnu.org>
14456 * gnutls.c (emacs_gnutls_deinit): New function.

14461 (deactivate_process): Call emacs_gnutls_deinit.
14463 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14465 * image.c (x_create_x_image_and_pixmap):
14466 * w32.c (sys_rename, w32_delayed_load):
14467 * w32font.c (fill_in_logfont):

14473 extracted from Fw32_default_color_map.
14474 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14476 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14478 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14480 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14482 * keyboard.c (test_undefined): New function (bug#9751).
14483 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14485 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14487 * sysdep.c (init_sys_modes): Fix the check for the controlling
14488 terminal (Bug#6649).
14490 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14492 * dispextern.h (struct bidi_it): New member next_en_type.
14494 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14495 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14496 current character, check also for next_en_type being WEAK_EN.
14497 (bidi_resolve_weak): Don't enter the expensive loop if the current
14498 position is before next_en_pos. Record the bidi type of the first
14499 non-ET, non-BN character we find, in addition to its position.
14500 (bidi_level_of_next_char): Invalidate next_en_type when
14501 next_en_pos is over-stepped.
14503 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14505 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14506 * editfns.c: Rewrite current-time-zone so that it invokes
14507 the equivalent of (format-time-string "%Z") to get the time zone name.
14508 This fixes a bug when the time zone name contains characters that
14509 need converting from the system time locale to Emacs internal format.
14510 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14511 that patch fixed format-time-string to do the conversion, but
14512 I forgot to fix current-time-zone.
14513 (format_time_string): New function, containing most of
14514 what Fformat_time_string used to contain.
14515 (Fformat_time_string): Rewrite in terms of format_time_string.
14516 This doesn't change this function's behavior.
14517 (current-time-zone): Rewrite to use format_time_string.
14518 This fixes the bug reported by Michael Schierl in
14519 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14520 Jason Rumney's 2007-06-07 change worked around this bug, but
14522 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14524 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14526 * xdisp.c (start_display): If the character at POS is displayed
14527 via a display vector, reset IT->current.dpvec_index to zero.
14528 (try_window_reusing_current_matrix): If a line ends in a display
14529 vector or the next line starts in a display vector, continue
14530 redrawing the window even though the character position of
14531 start_row was reached.
14534 2011-10-18 Chong Yidong <cyd@gnu.org>
14536 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14537 with nobreak-char-display too.
14539 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14541 Fix part 3 of bug#9771.
14542 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14543 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14544 non-neutral characters if the current character is a paragraph
14545 separator (a.k.a. Newline). This avoids running the same
14546 expensive loop twice, once when we consume the preceding newline
14547 and the other time when the line actually needs to be displayed.
14548 Avoid the loop when we see neutrals on the base embedding level
14549 following a character whose directionality is the same as the
14550 paragraph's. This avoids running the expensive loop when a line
14551 ends in a long sequence of neutrals, like control characters.
14552 Add assertion against STRONG_AL type. Slightly rearrange code
14553 that determines the type of a neutral given the first non-neutral
14555 (bidi_level_of_next_char): Set next_en_pos to zero when
14556 invalidating its info.
14558 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14560 * xdisp.c (push_display_prop): Determine whether to record string
14561 or buffer position by IT->string, not by IT->method. Allow
14562 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14563 (move_it_vertically_backward): Don't look for character position
14564 immediately after the newline when in a continuation line.
14567 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14569 * window.c (coordinates_in_window): Rewrite and delabelize
14570 vertical border check. (Bug#5357) (Bug#9618)
14572 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14574 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14575 errors in XSetWindowBorder (bug#9310).
14577 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14579 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14580 avoid crash when xmalloc overrun checking is enabled.
14582 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14584 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14585 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14586 cursor motion with <left> and <right> arrow keys.
14588 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14589 some callers set that themselves.
14591 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14593 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14594 display string and the previous row comes from the same string and
14595 is empty. (Bug#9739) (Bug#9738)
14597 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14599 * doc.c (get_doc_string): Encode file name (bug#9735).
14601 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14603 * bidi.c (bidi_level_of_next_char):
14604 * xdisp.c (get_visually_first_element): Remove old incorrect
14605 comments regarding the Unicode Line Separator character.
14607 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14609 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14611 * alloc.c (Fgc_status): Do not access beyond zombies array
14612 boundary if nzombies > MAX_ZOMBIES.
14613 * alloc.c (dump_zombies): Add missing format specifier.
14615 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14617 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14618 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14620 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14621 Some packages use them to denote characters with modifiers.
14623 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14625 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14626 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14627 matching a pp-number. Rename parameter var to var1.
14629 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14631 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14633 2011-10-08 Glenn Morris <rgm@gnu.org>
14635 * callint.c (Fcall_interactively): Give a more explicit error for the
14636 'c' case with a non-character input. (Bug#8479)
14638 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14640 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14642 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14643 lines that are hscrolled on the left.
14645 * dispnew.c (buffer_posn_from_coords): Account for a possible
14646 presence of header-line. (Bug#4426)
14648 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14650 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14651 Don't advertise functionality which we discourage or doesn't work.
14653 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14655 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14656 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14657 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14658 this makes Emacs dump core during garbage collection on rare
14659 occasions. sizeof is obviously inferior to offsetof here, so
14660 stick with offsetof.
14661 (GC_POINTER_ALIGNMENT): New macro.
14662 (mark_memory): Omit 3rd (offset) arg; caller changed.
14663 Don't assume EMACS_INT alignment is the same as pointer alignment.
14665 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14667 * keyboard.c (read_key_sequence_remapped): New var.
14668 (read_key_sequence): Compute remapping in the right buffer.
14669 (command_loop_1): Use read_key_sequence's remapping directly.
14671 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14673 * dired.c (file_name_completion): Don't expand file name.
14674 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14675 before checking file name handler.
14677 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14678 they've been requested explicitly (bug#9591).
14680 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14682 * keymap.c (Fsingle_key_description): Use make_specified_string
14683 instead of build_string to build string from push_key_description.
14686 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14688 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14689 This fixes a Y2038 bug on 64-bit hosts.
14690 * buffer.c (reset_buffer):
14691 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14692 (Fclear_buffer_auto_save_failure):
14693 Use 0, not -1, to represent an unset failure time, since time_t
14694 might not be signed.
14696 Remove dependency on glibc malloc internals.
14697 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14698 Move back here from lisp.h, but with their new implementations.
14699 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14700 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14701 * charset.c (charset_table_init): New static var.
14702 (syms_of_charset): Use it instead of xmalloc. This removes a
14703 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14704 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14705 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14706 Move back to alloc.c.
14707 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14708 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14710 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14712 * nsterm.m (windowDidResize): Call x_set_window_size only when
14713 ns_in_resize is true. Otherwise set pixelwidth/height and
14714 call change_frame_size (Bug#9628).
14716 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14718 Port --enable-checking=all to Fedora 14 x86-64.
14719 * charset.c (syms_of_charset): Also account for glibc malloc's
14720 internal overhead when calculating the initial malloc maximum.
14722 Port --enable-checking=all to Fedora 14 x86.
14723 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14725 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14726 (overrun_check_realloc, overrun_check_free):
14727 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14728 That way, xmalloc returns a properly-aligned pointer even if
14729 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14730 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14731 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14732 into account when calculating the initial malloc maximum.
14733 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14734 Move here from alloc.c, so that charset.c can use it too.
14735 Properly align; the old code wasn't right for common 32-bit hosts
14736 when configured with --enable-checking=all.
14737 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14738 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14740 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14742 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14745 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14747 * xdisp.c (compute_display_string_end): If there's no display
14748 string at CHARPOS, return -1.
14750 * bidi.c (bidi_fetch_char): When compute_display_string_end
14751 returns a negative value, treat the character as a normal
14752 character not covered by a display string. (Bug#9624)
14754 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14756 * lread.c (Fread_from_string): Fix typo in docstring.
14758 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14760 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14761 newline, reseat the iterator instead of bidi-iterating there one
14762 character at a time. (Bug#9610)
14763 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14764 TO_CHARPOS if the bidi iterator is at base embedding level.
14766 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14768 * lread.c (readevalloop): Use correct code for NBSP.
14769 (read1): Likewise. (Bug#9608)
14771 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14773 * dbusbind.c (Fdbus_register_signal): When service is not
14774 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14776 2011-09-25 Glenn Morris <rgm@gnu.org>
14778 * buffer.c (truncate-lines): Doc fix.
14780 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14782 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14783 (Fset_window_next_buffers): Doc fix.
14785 2011-09-24 Glenn Morris <rgm@gnu.org>
14787 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14789 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14791 Fix minor problems found by static checking.
14792 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14793 * indent.c (Fvertical_motion): Fix == vs = typo.
14795 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14797 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14798 Default value is now t. Doc fix.
14800 * indent.c (Fvertical_motion): Compute and apply the overshoot
14801 logic when moving up, not only when moving down. Fix the
14802 confusing name and values of the it_overshoot_expected variable;
14803 logic changes accordingly. (Bug#9254) (Bug#9549)
14805 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14806 CHARPOS is covered by a display string which includes newlines.
14807 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14808 is covered by a display string with embedded newlines.
14810 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14812 * dbusbind.c (Fdbus_register_signal): Add match rule to
14813 Vdbus_registered_objects_table. (Bug#9581)
14814 (Fdbus_register_method, Vdbus_registered_objects_table):
14817 2011-09-24 Jim Meyering <meyering@redhat.com>
14819 do not ignore write error for any output size
14820 The previous change was incomplete.
14821 While it makes emacs --batch detect the vast majority of stdout
14822 write failures, errors were still ignored whenever the output size is
14823 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14824 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14825 && echo FAIL: ignored write error
14826 FAIL: ignored write error
14827 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14828 && echo FAIL: ignored write error
14829 FAIL: ignored write error
14830 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14832 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14834 * emacs.c (Fkill_emacs): In noninteractive mode exit
14835 non-successfully if a write error occurred on stdout. (Bug#9574)
14837 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14839 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14842 * dispextern.h (struct it): Update the comment documenting what
14845 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14847 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14848 a display string, extend search for cursor position to end of row.
14849 (find_row_edges): If the row ends in a newline from a display
14850 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14851 Handle the case of a display string with multiple newlines.
14852 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14853 non-empty line. Fixes confusing cursor motion with arrow keys at
14854 the beginning of a line that starts with whitespace.
14856 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14858 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14861 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14863 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14864 boolean (Bug#9154).
14866 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14868 * xdisp.c (display_line): Record maximum and minimum buffer
14869 positions even if no glyphs were produced (e.g., by a zero-width
14870 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14871 buffer positions that will be removed from the glyph row because
14873 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14874 column is beyond frame width: don't subtract 1 "pixel" when
14875 computing width of the stretch.
14876 (reseat_at_next_visible_line_start): Undo the change made on
14877 2011-09-17 that saved paragraph information and restored it after
14878 the call to `reseat'. (Bug#9545)
14880 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14882 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14883 and turn window cursor on if cleared (Bug#9415).
14885 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14887 * search.c (boyer_moore): Take unibyte characters from pattern
14888 literally. (Bug#9458)
14890 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14892 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14894 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14896 Fix minor problem found by static checking.
14897 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14898 initialized, to pacify gcc -Wuninitialized.
14900 * fileio.c: Report proper errno when syscall falls.
14901 (Finsert_file_contents): Save and restore errno,
14902 so that report_file_error outputs the correct diagnostic.
14903 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14905 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14907 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14909 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14911 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14912 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14914 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14916 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14917 about the current paragraph and restore it after the call to reseat.
14919 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14920 (bidi_find_paragraph_start): Search back for paragraph beginning
14921 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14922 (bidi_move_to_visually_next): Only trigger paragraph-related
14923 computations when the last character is a newline or at EOB, not
14924 just any NEUTRAL_B. (Bug#9470)
14926 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14927 truncated lines if point is covered by a display string. (Bug#9524)
14929 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14931 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14932 (cons_to_x_long): New function.
14933 (lisp_data_to_selection_data): Use it. Correct the test for
14934 short-versus-long data; it was negated. Break out of vector
14935 loop, for efficiency, when a long datum is discovered.
14937 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14939 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14941 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14943 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14944 GCC PR/17406) by declaring this function with external scope.
14946 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14948 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14949 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14951 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14953 * editfns.c (Fformat): Correctly handle text properties on "%%".

14961 * xdisp.c (get_next_display_element)
14962 (fill_composite_glyph_string): Add comments about special meaning
14963 of TAB characters in a composition.
14965 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14967 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14968 This occurs when processing a multibyte format.
14969 Problem reported by Wolfgang Jenker.
14971 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14973 * xdisp.c (try_cursor_movement): Only check for exact match if
14974 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14976 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14978 Remove unused external symbols.
14979 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14980 * xdisp.c (calc_pixel_width_or_height): Now static.
14981 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14982 * indent.c (check_display_width):
14983 * w32term.c: Fix comment to match code.
14984 * xterm.c, xterm.h (x_catching_errors): Remove.
14986 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14988 * xselect.c: Use signed conversions more consistently (Bug#9498).
14989 (selection_data_to_lisp_data): Assume incoming selection data are
14990 signed integers, not unsigned. This is to be consistent with
14991 outgoing selection data, which was modified to use signed integers
14992 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14993 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14994 expects long, not unsigned long.
14996 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14998 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14999 computation of loop end. Reported by Johan Bockgård
15002 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15004 * frame.c (Fother_visible_frames_p): Function deleted.
15006 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15008 * indent.c (compute_motion): Process display vector front to back
15009 rather than the other way around. (Bug#2496)
15011 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15013 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15015 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15017 * minibuf.c (Fread_from_minibuffer): Doc fix.
15019 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15021 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15022 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15024 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15026 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15027 value for non-existent files.
15029 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15031 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15032 set its "size" to -1. This will set the modtime_size field of
15033 the corresponding buffer to -1, which is what
15034 verify-visited-file-modtime expects for files that do not exist.
15037 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15039 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15041 * lisp.h: ... from here. push_key_description is no longer
15042 defined in keyboard.c, so its declaration should not be in
15043 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15044 logically belongs with push_key_description.
15046 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15048 * buffer.h: Include <sys/types.h> instead of <time.h>.
15049 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15050 Problem reported by Herbert J. Skuhra.
15052 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15054 * xml.c (parse_region): Make the parsing work for
15055 non-comment-starting XML files again (bug#9144).
15057 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15059 * image.c (gif_load): Fix calculation of bottom and right corner.
15062 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15064 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15065 redisplay in small windows.
15067 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15069 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15071 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15073 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15074 Operate on live windows only.
15076 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15078 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15080 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15082 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15083 only under bidi iteration.
15085 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15087 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15089 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15091 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15092 Without this fix, the command to link temacs failed due to an
15093 undefined symbol __builtin_isnan. This is because
15094 /usr/include/iso/math_c99.h #defines isnan(x) to
15095 __builtin_isnan(x), but the bundled gcc, which identifies itself
15096 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15098 * floatfns.c (isnan): #undef, and then #define to a clone of
15100 (Fisnan): Always define, since it's always available now.
15101 (syms_of_floatfns): Always define isnan at the Lisp level.
15103 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15105 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15107 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15109 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15110 The previous code assumed that file offsets (off_t values) fit in
15111 EMACS_INT variables, which is not true on typical 32-bit hosts.
15112 The code messed up by falsely reporting buffer overflow in cases
15113 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15114 when "big" contains more than 2**29 bytes, even though this
15115 inserts just one byte and does not overflow the buffer.
15116 (Finsert_file_contents): Store file offsets as off_t
15117 values, not as EMACS_INT values. Check for overflow when
15118 converting between EMACS_INT and off_t. When checking for
15119 buffer overflow or for overlap, take the offsets into account.
15120 Don't use EMACS_INT for small values where int suffices.
15121 When checking for overlap, fix a typo: ZV was used where
15122 ZV_BYTE was intended.
15123 (Fwrite_region): Don't assume off_t fits into 'long'.
15124 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15126 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15128 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15130 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15132 sprintf-related integer and memory overflow issues (Bug#9412).
15134 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15135 (esprintf, exprintf, evxprintf): New functions.
15136 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15137 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15138 (modify_event_symbol): Do not assume that the length of
15139 name_alist_or_stem is safe to alloca and fits in int.
15140 (Fexecute_extended_command): Likewise for function name and binding.
15141 (Frecursion_depth): Wrap around reliably on integer overflow.
15142 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15143 since some callers pass EMACS_INT values.
15144 (Fsingle_key_description): Don't crash if symbol name contains more
15145 than MAX_ALLOCA bytes.
15146 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15147 (get_minibuffer): Arg is now EMACS_INT, not int.
15148 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15149 (esprintf, exprintf, evxprintf): New decls.
15150 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15152 * dbusbind.c (signature_cat): New function.
15153 (xd_signature, Fdbus_register_signal):
15154 Do not overrun buffer; instead, report string overflow.
15156 * dispnew.c (add_window_display_history): Don't overrun buffer.
15157 Truncate instead; this is OK since it's just a log.
15159 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15160 even if the time zone offset is outlandishly large.
15161 Don't mishandle offset == INT_MIN.
15163 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15164 when creating daemon; the previous buffer-overflow check was incorrect.
15166 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15167 which has the guts of the old verror function.
15169 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15170 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15172 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15173 (font_unparse_xlfd): Don't blindly alloca long strings.
15174 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15175 fits in int, when using sprintf. Use single snprintf to count
15176 length of string rather than counting it via multiple sprintfs;
15177 that's simpler and more reliable.
15178 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15179 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15180 sprintf, in case result does not fit in int.
15182 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15183 (fontset_from_font): Print it.
15185 * frame.c (tty_frame_count): Now printmax_t, not int.
15186 (make_terminal_frame, set_term_frame_name): Print it.
15187 (x_report_frame_params): In X, window IDs are unsigned long,
15188 not signed long, so print them as unsigned.
15189 (validate_x_resource_name): Check for implausibly long names,
15190 and don't assume name length fits in 'int'.
15191 (x_get_resource_string): Don't blindly alloca invocation name;
15192 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15195 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15196 (xg_check_special_colors, xg_set_geometry):
15197 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15199 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15200 Use esprintf, not sprintf, in case result does not fit in int.
15202 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15203 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15204 it as a large positive number.
15205 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15206 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15208 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15209 in case result does not fit in int.
15211 * print.c (float_to_string): Detect width overflow more reliably.
15212 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15213 buffer overrun. Don't assume list length fits in 'int'. Treat
15214 print length of 0 as 0, not as infinity; to be consistent with other
15215 uses of print length in this function. Don't overflow print length
15216 index. Don't assume hash table size fits in 'long', or that
15217 vectorlike size fits in 'unsigned long'.
15219 * process.c (make_process): Use printmax_t, not int, to format
15220 process-name gensyms.
15222 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15224 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15225 to avoid potential buffer overrun.
15227 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15228 if X resource line is longer than 512 bytes.
15230 * xfns.c (x_window): Make sprintf buffer a bit bigger
15231 to avoid potential buffer overrun.
15233 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15235 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15237 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15239 Integer overflow fixes for scrolling, etc.
15240 Without these, Emacs silently mishandles large integers sometimes.
15241 For example, "C-u 4294967297 M-x recenter" was treated as if
15242 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15244 * xdisp.c (try_window_id): Check Emacs fixnum range before
15245 converting to 'int'.
15247 * window.c (window_scroll_line_based, Frecenter):
15248 Check that an Emacs fixnum is in range before assigning it to 'int'.
15249 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15250 values converted from Emacs fixnums.
15251 (Frecenter): Don't wrap around a line count if it is out of 'int'
15252 range; instead, treat it as an extreme value.
15253 (Fset_window_configuration, compare_window_configurations):
15254 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15256 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15257 that can exceed INT_MAX. Check that EMACS_INT value is in range
15258 before assigning it to the (possibly-narrower) index.
15259 (match_limit): Don't assume that a fixnum can fit in 'int'.
15261 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15264 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15265 (Fvertical_motion): Don't wrap around LINES values that don't fit
15266 in 'int'. Instead, treat them as extreme values. This is good
15267 enough for windows, which can't have more than INT_MAX lines anyway.
15269 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15271 * Require libxml/parser.h to avoid compilation warning.
15273 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15275 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15276 since this reportedly can destroy thread storage.
15278 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15280 * syntax.c (find_defun_start): Update all cache variables if
15281 exiting early (Bug#9401).
15283 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15285 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15287 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15288 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15289 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15291 * term.c (tty_append_glyph): New function.
15292 (produce_stretch_glyph): Static function and its prototype deleted.
15294 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15297 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15299 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15300 when checking :margin (Bug#9390).
15301 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15302 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15303 so that the name doesn't mislead. All uses changed.
15305 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15307 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15310 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15312 * xdisp.c (move_it_to): Don't bail out early when reaching
15313 position beyond to_charpos, if we are scanning backwards.
15314 (move_it_vertically_backward): When DY == 0, make sure we get to
15315 the first character in the line after the newline.
15317 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15319 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15320 (ccl_driver): Do not generate an out-of-range pointer.
15321 (Fccl_execute_on_string): Remove unnecessary check for
15322 integer overflow, noted by Stefan Monnier in
15323 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15324 Remove a FIXME that didn't need fixing.
15325 Simplify the newly-introduced buffer reallocation code.
15327 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15329 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15331 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15333 Integer and memory overflow issues (Bug#9196).
15335 * doc.c (get_doc_string): Rework so that
15336 get_doc_string_buffer_size is the actual buffer size, rather than
15337 being 1 less than the actual buffer size; this makes xpalloc more
15340 * image.c (x_allocate_bitmap_record, cache_image):
15341 * xselect.c (Fx_register_dnd_atom):
15342 Simplify previous changes by using xpalloc.
15344 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15345 since either will do and ptrdiff_t is convenient with xpalloc.
15347 * charset.c (charset_table_size)
15348 (struct charset_sort_data.priority): Now ptrdiff_t.
15349 (charset_compare): Don't overflow if priorities differ greatly.
15350 (Fsort_charsets): Don't assume list length fits in int.
15351 Check for size-calculation overflow when allocating sort data.
15352 (syms_of_charset): Allocate an initial charset table that is
15353 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15355 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15357 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15358 The actual value is always <= INT_MAX, and leaving it unsigned made
15359 overflow checking harder.
15361 * dispextern.h (struct glyph_matrix.rows_allocated)
15362 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15363 with xpalloc. The values are still always <= INT_MAX.
15365 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15367 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15368 (SAFE_NALLOCA): New macro.
15370 * region-cache.c (struct boundary.pos, find_cache_boundary)
15371 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15372 (set_cache_region, invalidate_region_cache)
15373 (revalidate_region_cache, know_region_cache, region_cache_forward)
15374 (region_cache_backward, pp_cache):
15375 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15376 so that ptrdiff_t * can be passed to xpalloc.
15377 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15378 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15379 (pp_cache): Don't assume cache_len fits in int.
15380 * region-cache.h: Adjust extern decls to match.
15382 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15383 EMACS_INT, since either will do, for xpalloc.
15385 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15386 (xnmalloc, xnrealloc, xpalloc): New functions.
15388 * bidi.c (bidi_shelve_header_size): New constant.
15389 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15390 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15392 * bidi.c (bidi_cache_shrink):
15393 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15395 Don't update size of array until after memory allocation succeeds,
15396 because xmalloc/xrealloc may not return.
15397 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15398 now that we have proper integer overflow checking.
15399 (record_overlay_string, overlay_strings): Catch overflows when
15400 calculating size of overlay_str_buf.
15402 * callproc.c (Fcall_process): Check for size overflow when
15403 calculating size of args2.
15404 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15405 Normally we prefer signed values, but sticking with ptrdiff_t would
15406 require adding more-complicated checks.
15408 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15409 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15410 Redo buffer-overflow calculations to avoid integer overflow.
15411 Add a FIXME comment where memory seems to be over-allocated.
15413 * character.c (Fstring): Check for size-calculation overflow.
15415 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15416 unnecessary integer overflow. Check for size overflow.
15417 (encode_coding_object): Don't update size until xmalloc succeeds.
15419 * composite.c (get_composition_id): Check for overflow in glyph
15420 length calculations.
15422 Integer and memory overflow fixes for display code.
15423 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15424 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15425 (scrolling_window): Check for overflow in size calculations.
15426 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15427 Don't assume glyph table len fits in int.

15429 (row_table_size): Now ptrdiff_t, not int.
15430 (scrolling_window): Avoid overflow in size calculations.
15431 Don't update size until allocation succeeds.
15432 * fns.c (concat): Check for overflow in size calculations.
15433 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15434 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15435 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15437 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15438 (get_doc_string): Check for size calculation overflow.
15439 Don't update size until allocation succeeds.
15440 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15441 EMACS_INT, where ptrdiff_t will do.
15442 (Fsubstitute_command_keys): Check for string overflow.
15444 * editfns.c (set_time_zone_rule): Don't assume environment length
15446 (message_length): Now ptrdiff_t, not int.
15447 (Fmessage_box): Don't update size until allocation succeeds.
15448 Don't assume message length fits in int.
15449 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15451 * emacs.c (main): Do not reallocate argv, since there is a null at
15452 the end that can be overwritten, and this way there's no need to
15453 worry about size-calculation overflow.
15454 (sort_args): Check for size-calculation overflow.
15456 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15458 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15460 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15461 (x_set_scroll_bar_width, x_figure_window_size):
15462 Check for integer overflow.
15463 (x_set_alpha): Do not assume XINT fits in int.
15465 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15466 This is for the members text_lines, text_cols, total_lines, total_cols,
15467 where the system imposes an 'int' limit.
15469 * fringe.c (Fdefine_fringe_bitmap):
15470 Don't update size until alloc works.
15472 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15473 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15475 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15476 Check for size-calculation overflow.
15477 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15478 do, as we prefer signed integers.
15479 (id_to_widget.max_size, id_to_widget.used)
15480 (xg_store_widget_in_map, xg_remove_widget_from_map)
15481 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15482 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15483 Use and return ptrdiff_t, not int.
15484 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15485 * gtkutil.h: Change prototypes to match the above.
15487 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15488 are duplicate now that they've been promoted to lisp.h.
15489 (x_allocate_bitmap_record, x_alloc_image_color)
15490 (make_image_cache, cache_image, xpm_load):
15491 Don't update size until alloc is done.
15492 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

15495 (ct_colors_allocated_max): New constant.
15496 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15499 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15500 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15501 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15502 Use ptrdiff_t, not int, to count maps.
15503 (read_char_minibuf_menu_prompt): Check for overflow in size
15504 calculations. Don't update size until allocation succeeds.
15505 Redo calculations to avoid overflow.
15506 * keyboard.h: Change prototypes to match the above.
15508 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15510 (current_minor_maps): Check for size calculation overflow.
15511 * keymap.h: Change prototypes to match the above.
15513 * lread.c (read1, init_obarray): Don't update size until alloc done.
15515 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15534 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15535 for command line length. Do not attempt to address one before the
15536 beginning of an array, as that's not portable.
15538 * term.c (max_frame_lines): Remove; unused.
15539 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15541 (encode_terminal_code, calculate_costs): Check for size
15542 calculation overflow.

15560 Use ptrdiff_t, not int, for sizes.
15561 (store_mode_line_noprop_char): Don't update size until alloc done.

15564 Use ptrdiff_t, not int, for sizes.
15565 (Finternal_make_lisp_face, cache_face):
15566 Check for size calculation overflow.
15567 (cache_face): Treat size calculation overflows as if they were
15568 memory exhaustion (the usual treatment), rather than aborting.
15570 * xfns.c (x_encode_text, x_set_name_internal)
15571 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15572 sizes, since they can exceed INT_MAX in size. Check for size
15573 calculation overflow.
15575 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15576 (xg_select): Check for size calculation overflow.
15577 Don't update size until alloc done.
15579 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15580 as sprintf is limited to int lengths.
15582 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15583 (X_LONG_MIN): New macros.
15584 Use them to make the following changes clearer.
15585 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15586 This change doesn't affect the value now, but it may help remind
15587 future maintainers not to raise the value too much later.
15588 (SELECTION_QUANTUM): Remove, replacing with ...
15589 (selection_quantum): ... new function, which avoids overflow.
15591 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

15595 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15596 (lisp_data_to_selection_data, clean_local_selection_data):
15597 Use ptrdiff_t, not int, to record length of selection.
15598 (x_reply_selection_request, x_get_window_property)
15599 (receive_incremental_selection, x_property_data_to_lisp):
15600 Redo calculations to avoid overflow.
15601 (x_reply_selection_request): When sending hint, ceiling it at
15602 X_LONG_MAX rather than relying on wraparound overflow to send
15604 (x_get_window_property, receive_incremental_selection)
15605 (lisp_data_to_selection_data, x_property_data_to_lisp):

15609 Don't store size until memory allocation succeeds.
15610 (x_get_window_property): Plug memory leak on memory exhaustion.
15611 Don't double-block input; malloc is safe here. Don't assume 2**34
15612 - 4 fits in unsigned long. Add an xassert to check
15613 XGetWindowProperty overflow. Be more careful about overflow
15614 calculations, and distinguish size from memory overflow better.
15615 (receive_incremental_selection): When tracing, don't assume
15616 unsigned int is less than INT_MAX.
15617 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15618 harmful) conversions of unsigned short to int.
15619 (lisp_data_to_selection_data): Don't assume that integers
15620 in the range -65535 through -1 fit in an X unsigned short.
15621 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15622 result parameters unless successful. Rely on cons_to_unsigned
15623 to report problems with elements; the old code wasn't right anyway.
15624 (x_check_property_data): Check for int overflow; we cannot use
15625 a wider type due to X limits.
15626 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

15631 (x_term_init): Check for size calculation overflow.
15632 (x_color_cells): Don't store size until memory allocation succeeds.
15633 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15634 Don't assume alloca size is less than MAX_ALLOCA.
15635 (x_term_init): Don't assume length fits in int (sprintf is limited
15638 Use ptrdiff_t for composition IDs.

15658 * lisp.h (hash_lookup, hash_put):
15659 * minibuf.c (Ftest_completion):
15660 Use ptrdiff_t for hash table indexes, not int (which is too
15661 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15662 32-bit --with-wide-int hosts).
15664 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15665 Add a FIXME comment about memory leaks.
15666 (syms_of_charset): Don't assume xmalloc returns.

15670 * character.h (CHAR_WIDTH):
15671 * indent.c (MULTIBYTE_BYTES_WIDTH):
15672 Use sanitize_char_width to avoid undefined and/or bad behavior
15673 with outlandish widths.
15674 * character.h (sanitize_tab_width): Rename from sanitize_width,
15675 now that we have two such functions. All uses changed.

15687 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15689 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15690 Remove unreachable code.
15691 (read_hex, load_charset_map_from_file): Check for integer overflow.
15693 * xterm.c: Don't go over XClientMessageEvent limit.
15694 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15695 (x_send_scroll_bar_event): Likewise. Check that the size does not
15696 exceed limits imposed by XClientMessageEvent, as well as the usual
15697 ptrdiff_t and size_t limits.
15699 * keyboard.c: Overflow, signedness and related fixes.
15700 (make_lispy_movement): Use same integer type in forward decl
15701 that is used in the definition.
15702 (read_key_sequence, keyremap_step):
15703 Change bufsize argument back to int, undoing my 2011-03-30 change.
15704 We prefer signed types, and int is wide enough here.
15705 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15706 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15707 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15708 length, not size_t. Use ptrdiff_t for index, not int.
15709 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15710 possibility of integer overflow.
15712 Overflow, signedness and related fixes for images.

15733 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15734 (lookup_image): Remove unnecessary tests.
15735 (xbm_image_p): Locals are now of int, not EMACS_INT,
15736 since parse_image_check makes sure they fit into int.
15737 (png_load, gif_load, svg_load_image):
15738 Prefer int to unsigned where either will do.
15739 (tiff_handler): New function, combining the cores of the
15740 old tiff_error_handler and tiff_warning_handler.
15741 This function is rewritten to use vsnprintf and thereby avoid
15742 stack buffer overflows. It uses only the features of vsnprintf
15743 that are common to both POSIX and native Microsoft.
15744 (tiff_error_handler, tiff_warning_handler): Use it.
15745 (tiff_load, gif_load, imagemagick_load_image):
15746 Don't assume :index value fits in 'int'.
15747 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15748 (imagemagick_load_image): Check that crop parameters fit into
15749 the integer types that MagickCropImage accepts. Don't assume
15750 Vimagemagick_render_type has a nonnegative value. Don't assume
15751 size_t fits in 'long'.
15752 (gs_load): Use printmax_t to print the widest integers possible.
15753 Check for integer overflow when computing image height and width.
15755 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15757 * xdisp.c (redisplay_window): Don't force window start if point
15758 will be invisible in the resulting window. (Bug#9324)

15762 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15763 the display spec is of the form `(space ...)'.
15764 (handle_display_spec): Return the value returned by
15765 handle_single_display_spec, not just 1 or zero.
15766 (handle_single_display_spec): If the display spec is of the form
15767 `(space ...)', and specifies display in the text area, return 2
15769 (try_cursor_movement): Check for the need to scroll more
15770 accurately, and prefer exact match for point under bidi.
15771 Don't advance `row' beyond the last row of the window.
15773 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15774 into disp_prop; all users changed.
15776 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15777 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15778 for the text covered by the display property.

15788 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15789 buffers, return left-to-right.
15790 (set_cursor_from_row): Consider candidate row a win if its glyph
15791 represents a newline and point is on that newline. Fixes cursor
15792 positioning on the newline at EOL of R2L text within L2R
15793 paragraph, and vice versa.
15794 (try_cursor_movement): Check continued rows, in addition to
15795 continuation rows. Fixes unwarranted scroll when point enters a
15796 continued line of R2L text within an L2R paragraph, or vice versa.
15797 (cursor_row_p): Consider the case of point being equal to
15798 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15799 from the end of a short line to the beginning of a continued line
15800 of R2L text within L2R paragraph.
15801 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15802 composed characters.

15817 2011-08-22 Kenichi Handa <handa@m17n.org>
15819 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15820 extra slot even if the purpose is char-code-property-table.
15822 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15824 * xdisp.c (redisplay_window): When computing centering_position,
15825 account for the height of the header line. (Bug#8874)
15827 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15828 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15829 candidate is selected by the mouse, and that candidate has a
15830 composed character under the mouse.
15832 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15833 coordinates reported by pos-visible-in-window-p for a composed
15834 character in column zero.
15836 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15838 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15840 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15842 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15843 consider it a hit if to_charpos is anywhere in the range of the
15844 composed buffer positions.
15846 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15848 * image.c (gif_load): Don't assume that each subimage has the same
15849 dimensions as the base image. Handle disposal method that is
15850 "undefined" by the gif spec (Bug#9335).
15852 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15854 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15855 (Fcondition_case): Document `debug' symbol in error handler.
15857 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15859 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15860 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15861 from an Org mode buffer to a Speedbar frame.
15863 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15864 a composition, take its buffer position from IT->cmp_it.charpos.
15865 Fixes cursor positioning at the beginning of a line that begins
15866 with a composed character.
15868 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15870 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15871 character bidirectional type, use STRONG_L instead. Fixes crashes
15872 in a buffer produced by `describe-categories'.
15874 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15875 members before the level stack, so they would be saved and
15876 restored when copying iterator state. Fixes incorrect reordering
15877 around TABs covered by display properties.
15879 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15881 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15885 * eval.c (internal_condition_case, internal_condition_case_1)
15886 (internal_condition_case_2, internal_condition_case_n):
15887 Remove unnecessary aborts (Bug#9081).
15889 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15891 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15892 has no `load' handler, try opening the file locally. (Bug#9311)
15894 2011-08-16 Ken Brown <kbrown@cornell.edu>
15896 * gmalloc.c: Expand comment.

15900 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15901 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15903 2011-08-16 Ken Brown <kbrown@cornell.edu>
15905 Fix memory allocation problems in Cygwin build (Bug#9273).
15907 * unexcw.c ( __malloc_initialized): Declare external variable.
15908 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15910 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):

15940 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
15941 coordinates of the iterator when restoring from ppos_it.
15944 2011-08-14 Kenichi Handa <handa@m17n.org>
15946 * process.c (create_process): Call setup_process_coding_systems

15949 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15951 * xdisp.c (move_it_in_display_line_to): Don't invoke
15952 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15953 ppos_it. Fixes vertical cursor motion when line beginning is
15954 covered by an image. (Bug#9296)
15956 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15958 * nsterm.h (ns_run_ascript): Declare.

15961 * nsfns.m (as_script, as_result, as_status): New static variables.
15962 (ns_run_ascript): New function.
15963 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15964 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15965 the event loop. Get status from as_status (Bug#7276).
15967 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15968 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15969 the event loop (Bug#7276).
15971 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15973 * gnutls.c (QCgnutls_bootprop_priority)

15994 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15995 (Fnetwork_interface_list): Allocate in increments of bytes instead
15996 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15997 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15999 (struct ifflag_def): notrailers is smart on OSX.
16000 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16001 Get hardware address with getifaddrs if available.
16003 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16005 * xdisp.c (iterate_out_of_display_property): xassert that
16006 IT->position is set to within IT->object's boundaries. Break from
16007 the loop as soon as EOB is reached; avoids infloops in redisplay
16008 when IT->position is set up wrongly due to some bug.
16009 Set IT->current to match the bidi iterator unconditionally.
16010 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16011 entry. Force push_it to save on the stack the current
16012 buffer/string position, to be restored by pop_it. Fix flags in
16013 the iterator structure wrt the object coming from a display
16014 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16015 properties. (Bug#9284)
16017 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16019 * fontset.c (fontset_get_font_group): Add proper type checks.

16029 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16031 * xdisp.c (forward_to_next_line_start): Allow to use the
16032 no-display-properties-and-no-overlays under bidi display.
16033 Set disp_pos in the bidi iterator to avoid searches for display
16034 properties and overlays.
16036 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16038 * editfns.c (Fset_time_zone_rule): Document relationship with the

16042 the font entity extracted from the cache (Bug#8109).
16044 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16046 * composite.c (autocmp_chars): Don't reset point. That is done by
16047 restore_point_unwind (Bug#5984).
16049 2011-08-07 Juri Linkov <juri@jurta.org>
16051 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16052 to show the arg `TIME' instead of `TIMEVAL'.
16054 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16056 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16057 display property strides EOL and includes a newline, as in
16058 longlines-mode. (Bug#9254)
16059 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16060 word-wrap under bidirectional display. (Bug#9224)
16062 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16063 is non-zero, even if the data buffer is NULL. Fixes a crash in
16064 vertical-motion with longlines-mode. (Bug#9254)
16066 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16068 * bidi.c <bidi_cache_total_alloc>: Now static.
16069 (bidi_initialize): Initialize bidi_cache_total_alloc.
16071 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16074 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16075 amount allocated this far in `bidi_cache_total_alloc'.
16076 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16077 non-zero, only free the data buffer without restoring the cache
16078 contents. All callers changed.
16080 * dispextern.h (bidi_unshelve_cache): Update prototype.
16082 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16083 (move_it_in_display_line, move_it_to)
16084 (move_it_vertically_backward, move_it_by_lines): Replace the call
16085 to xfree to an equivalent call to bidi_unshelve_cache.
16086 (move_it_in_display_line_to): Fix logic of returning
16087 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16089 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16091 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16092 came from a string character with a `cursor' property. (Bug#9229)
16094 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16096 * Makefile.in (LIB_PTHREAD): New variable.
16097 (LIBES): Add LIB_PTHREAD (Bug#9216).
16099 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16100 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16102 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16104 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16106 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16108 * xterm.c (x_find_topmost_parent): New function.
16109 (x_set_frame_alpha): Find topmost parent window with
16110 x_find_topmost_parent and set the property there also (bug#9181).
16111 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16113 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16115 * callproc.c (Fcall_process): Avoid vfork clobbering
16116 the local vars buffer, coding_systems, current_dir.
16118 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16120 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16122 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16124 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16125 so that it is not optimized away.
16127 * xdisp.c (compute_display_string_pos): Remove unused local.
16129 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16131 Fix slow cursor motion and scrolling in large buffers with
16132 selective display, like Org Mode buffers. (Bug#9218)
16134 * dispextern.h (struct bidi_it): New member disp_prop_p.
16136 * xdisp.c: Remove one-slot cache of display string positions.
16137 (compute_display_string_pos): Accept an additional argument
16138 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16139 for a display string or property. If found, set DISP_PROP_P
16142 * bidi.c (bidi_fetch_char): Accept an additional argument
16143 DISP_PROP_P, and pass it to compute_display_string_pos.
16144 Only handle text covered by a display string if DISP_PROP_P is returned
16145 non-zero. All callers of bidi_fetch_char changed.
16147 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16149 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16151 2010-12-03 Don March <don@ohspite.net>
16153 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16154 last character M-[char] is translated to ESC [char] (bug#7541).
16156 2011-08-02 Kenichi Handa <handa@m17n.org>
16158 * lisp.h (uniprop_table): Extern it.
16160 * chartab.c (uniprop_table): Make it non-static.
16162 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16164 * xdisp.c (forward_to_next_line_start): Accept additional argument
16165 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16167 (reseat_at_next_visible_line_start): Use the bidi iterator state
16168 returned by forward_to_next_line_start to restore the state of
16169 it->bidi_it after backing up to previous newline. (Bug#9212)
16171 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16173 * regex.c (re_comp): Protoize.
16174 (re_exec): Fix return type.
16175 (regexec): Fix type of `ret'. (Bug#9203)
16177 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16179 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16180 This is needed if max-image-size is a floating-point number.
16182 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16184 * print.c (print_object): Print empty symbol as ##.
16186 * lread.c (read1): Read ## as empty symbol.
16188 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16190 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16191 setting frame foreground color (Bug#9175).
16192 (x_set_background_color): Likewise.
16194 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16195 contents (Bug#9176).
16196 (EmacsTooltip -init): Remove bezels and add shadows to
16199 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16200 or scroll bar (Bug#8470).
16202 * nsfont.m (nsfont_open): Remove assignment to voffset and
16203 unnecessary vars hshink, expand, hd, full_height, min_height.
16204 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16206 * nsterm.h (nsfont_info): Remove voffset field.
16208 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16210 Implement strike-through and overline on NextStep (Bug#8863).
16212 * nsfont.m (nsfont_open): Use underline position provided by font,
16213 instead of hard-coded value of 2.
16214 (nsfont_draw): Call ns_draw_text_decoration instead.
16216 * nsterm.h: Add declaration for ns_draw_text_decoration.
16218 * nsterm.m (ns_draw_text_decoration): New function for drawing
16219 underline, overline, and strike-through.
16220 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16221 ns_draw_text_decoration. Change treatment of cursor drawing to
16222 accommodate underlining, etc.
16224 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16226 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16229 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16231 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16232 Without this fix, if a signal arrives just after memory fills up,
16233 'malloc' might be invoked reentrantly.
16235 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16236 In other words, assume that every image size is allowed, on non-X
16237 hosts. This assumption is probably wrong, but it lets Emacs compile.
16239 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16241 * regex.c (re_iswctype): Convert return values to boolean.
16243 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16245 * xdisp.c (compute_display_string_pos): Don't use cached display
16246 string position if the buffer had its restriction changed.
16249 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16251 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16253 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16255 Integer signedness and overflow and related fixes. (Bug#9079)
16257 * bidi.c: Integer size and overflow fixes.
16258 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16259 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16260 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16261 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16262 (bidi_find_other_level_edge):
16263 Use ptrdiff_t instead of EMACS_INT where either will do.
16264 This works better on 32-bit hosts configured --with-wide-int.
16265 (bidi_cache_ensure_space): Check for size-calculation overflow.
16266 Use % rather than repeated addition, for better worst-case speed.
16267 Don't set bidi_cache_size until after xrealloc returns, because it
16269 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16270 (bidi_cache_ensure_space): Also check that the bidi cache size
16271 does not exceed that of the largest Lisp string or buffer. See Eli
16272 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16274 * alloc.c (__malloc_size_t): Remove.
16275 All uses replaced by size_t. See Andreas Schwab's note
16276 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16278 * image.c: Improve checking for integer overflow.
16279 (check_image_size): Assume that f is nonnull, since
16280 it is always nonnull in practice. This is one less thing to
16281 worry about when checking for integer overflow later.
16282 (x_check_image_size): New function, which checks for integer
16283 overflow issues inside X.
16284 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16285 This removes the need for a memory_full check.
16286 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16287 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16288 (xbm_read_bitmap_data): Change locals back to 'int', since
16289 their values must fit in 'int'.
16290 (xpm_load_image, png_load, tiff_load):
16291 Invoke x_create_x_image_and_pixmap earlier,
16292 to avoid much needless work if the image is too large.
16293 (tiff_load): Treat overly large images as if
16294 x_create_x_image_and_pixmap failed, not as malloc failures.
16295 (gs_load): Use x_check_image_size.
16297 * gtkutil.c: Omit integer casts.
16298 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16299 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16301 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16303 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16304 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16305 would wrongly return t on a 64-bit host.
16307 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16308 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16309 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16310 and therefore cause GCC to emit a bogus diagnostic in some cases.
16312 * image.c: Integer signedness and overflow and related fixes.
16313 This is not an exhaustive set of fixes, but it's time to
16314 record what I've got.
16315 (lookup_pixel_color, check_image_size): Remove redundant decls.
16316 (check_image_size): Don't assume that arbitrary EMACS_INT values
16317 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16318 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16319 (tiff_load, imagemagick_load_image):
16320 Check for overflow in size calculations.
16321 (x_create_x_image_and_pixmap): Remove unnecessary test for
16322 xmalloc returning NULL; that can't happen.
16323 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16324 (xpm_color_bucket): Use better integer hashing function.
16325 (xpm_cache_color): Don't possibly over-allocate memory.
16326 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16327 (gif_memory_source):
16328 Use ptrdiff_t, not int or size_t, to record sizes.
16329 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16330 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16331 either works, as we prefer signed integers.
16332 (tiff_read_from_memory, tiff_write_from_memory):
16333 Return tsize_t, not size_t, since that's what the TIFF API wants.
16334 (tiff_read_from_memory): Don't fail simply because the read would
16335 go past EOF; instead, return a short read.
16336 (tiff_load): Omit no-longer-needed casts.
16337 (Fimagemagick_types): Don't assume size fits into 'int'.
16339 Improve hashing quality when configured --with-wide-int.
16340 * fns.c (hash_string): New function, taken from sxhash_string.
16341 Do not discard information about ASCII character case; this
16342 discarding is no longer needed.
16343 (sxhash-string): Use it. Change sig to match it. Caller changed.
16344 * lisp.h: Declare it.
16345 * lread.c (hash_string): Remove, since we now use fns.c's version.
16346 The fns.c version returns a wider integer if --with-wide-int is
16347 specified, so this should help the quality of the hashing a bit.
16349 * emacs.c: Integer overflow minor fix.
16350 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16351 Define only if GNU_LINUX.
16352 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16354 * dispnew.c: Integer signedness and overflow fixes.
16355 Remove unnecessary forward decls, that were a maintenance hassle.
16356 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16358 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16359 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16360 (prepare_desired_row, line_draw_cost):
16361 Use int, not unsigned, where either works.
16362 (save_current_matrix, restore_current_matrix):
16363 Use ptrdiff_t, not size_t, where either works.
16364 (init_display): Check for overflow more accurately, and without
16365 relying on undefined behavior.
16367 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16368 Remove, replacing with the new symbols in lisp.h. All uses changed.
16369 * fileio.c (make_temp_name):
16370 * filelock.c (lock_file_1, lock_file):
16371 * xdisp.c (message_dolog):
16372 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16373 Use pMd etc. instead.
16374 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16375 replacing the pWIDE etc. symbols removed from editfns.c.
16377 * keyboard.h (num_input_events): Now uintmax_t.
16378 This is (very slightly) less likely to mess up due to wraparound.
16381 * buffer.c: Integer signedness fixes.
16382 (alloc_buffer_text, enlarge_buffer_text):
16383 Use ptrdiff_t rather than size_t when either will do, as we prefer
16386 * alloc.c: Integer signedness and overflow fixes.
16387 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16388 (__malloc_size_t): Default to size_t, not to int.
16389 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16390 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16391 Prefer ptrdiff_t to size_t when either would do, as we prefer
16393 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16394 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16395 Now const. Initialize with values that are in range even if char
16397 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16398 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16399 These functions do the right thing with sizes > 2**32.
16400 (check_depth): Now ptrdiff_t, not int.
16401 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16402 Adjust to new way of storing sizes. Check for size overflow bugs
16404 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16405 slightly wrong anyway, as it missed one instance of
16406 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16407 (refill_memory_reserve): Omit needless cast to size_t.
16408 (mark_object_loop_halt): Mark as externally visible.
16410 * xselect.c: Integer signedness and overflow fixes.
16411 (Fx_register_dnd_atom, x_handle_dnd_message):
16412 Use ptrdiff_t, not size_t, since we prefer signed.
16413 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16414 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16415 x_dnd_atoms_size and x_dnd_atoms_length.
16417 * doprnt.c: Prefer signed to unsigned when either works.
16419 * doprnt.c (doprnt):
16421 * xdisp.c (vmessage):
16422 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16423 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16424 prefer signed arithmetic to avoid comparison confusion.
16425 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16426 but is a bit tricky.
16428 Assume freestanding C89 headers, string.h, stdlib.h.
16429 * data.c, doprnt.c, floatfns.c, print.c:
16430 Include float.h unconditionally.
16431 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16432 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16433 * regex.c: Likewise for stddef.h, string.h.
16434 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16435 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16436 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16437 (STDC_HEADERS): Remove obsolete defines.
16438 * sysdep.c: Include limits.h unconditionally.
16440 Assume support for memcmp, memcpy, memmove, memset.
16441 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16442 * regex.c (memcmp, memcpy):
16443 Remove; we assume C89 now.
16445 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16446 (__malloc_safe_bcopy): Remove; no longer needed.
16448 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16449 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16450 well either way, and we prefer signed to unsigned.
16452 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16454 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16455 closes the connection while we're reading (bug#9182).
16457 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16459 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16460 are specified (Bug#9168).
16462 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16464 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16465 Found by GCC static checking and --with-wide-int on a 32-bit host.
16467 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16469 * xdisp.c (compute_display_string_pos): Fix logic of caching
16470 previous display string position. Initialize cached_prev_pos to
16471 -1. Fixes slow-down at the beginning of a buffer.
16473 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16475 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16476 for attrs[LFACE_FONTSET_INDEX].

16480 * xml.c (parse_region): Remove unused local
16481 that was recently introduced.
16483 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16485 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16486 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16488 * xdisp.c (move_it_in_display_line_to): Record the best matching
16489 position for TO_CHARPOS while scanning the line, and restore it on
16490 exit if none of the characters scanned was an exact match.
16491 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16492 when exact match is impossible due to invisible text, and the
16493 lines are truncated.
16495 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16497 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16500 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16502 Fix a significant slow-down of cursor motion with C-n, C-p,
16503 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16504 auto-repeat under bidi redisplay in fontified buffers.
16505 * xdisp.c (compute_stop_pos_backwards): New function.
16506 (next_element_from_buffer): Call compute_stop_pos_backwards to
16507 find a suitable prev_stop when we find ourselves before
16509 (reseat): Don't look for prev_stop, as that could mean a very long
16511 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16512 <cached_disp_overlay_modiff>: Cache for last found display string
16514 (compute_display_string_pos): Return the cached position if asked
16515 about the same buffer in the same area of character positions, and
16516 the buffer wasn't changed since the time the display string
16517 position was cached.
16519 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16521 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16522 is an integer, which is important for empty lines. (Bug#9149)
16524 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16526 * frame.c (Fmodify_frame_parameters): In tty case, update the
16527 default face if necessary (Bug#4238).
16529 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16531 * editfns.c (Fstring_to_char): No need to explain what a character
16532 is in the docstring (Bug#6576).
16534 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16536 * xml.c (parse_region): Make sure we always return a tree.
16538 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16540 * xml.c (parse_region): If a document contains only comments,
16543 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16545 * xml.c (make_dom): Return comments, too.
16547 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16550 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16551 and the surrounding thread.
16552 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16553 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16554 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16556 * s/openbsd.h (BROKEN_SIGIO): Define.
16557 * unexelf.c (unexec) [__OpenBSD__]:
16558 Don't update the .mdebug section of the Alpha COFF symbol table.
16560 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16562 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16565 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16567 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16568 This fixes some race conditions on the permissions of any newly
16571 * alloc.c (valid_pointer_p): Use pipe, not open.
16572 This fixes some permissions issues when debugging.
16574 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16575 If fchown fails to set both uid and gid, try to set just gid,
16576 as that is sometimes allowed. Adjust the file's mode to eliminate
16577 setuid or setgid bits that are inappropriate if fchown fails.
16579 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16581 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16593 symbol character follows.
16595 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16597 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16598 This works around a problem with the previous change to Fcopy_file.
16599 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16600 and without this change, GCC might complain about discarding
16601 fchown's return value.
16603 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16605 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16607 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16609 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16611 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16613 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16614 it's used from the C level.
16616 * process.c: Use the same condition for POLL_FOR_INPUT in both
16617 keyboard.c and process.c (bug#1858).
16619 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16621 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16622 (Fgnutls_boot): Use it.
16624 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16626 * doc.c (Fsubstitute_command_keys): Revert last change.
16628 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16630 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16631 quotes the next character, and doesn't affect other longer
16632 sequences (bug#8935).
16634 * lread.c (syms_of_lread): Clarify that is isn't only
16635 `eval-buffer' and `eval-defun' that's affected by
16636 `lexical-binding' (bug#8460).
16638 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16640 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16641 bidi redisplay when a line includes both an image and is truncated.
16643 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16645 Fix minor problems found by static checking.
16646 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16647 (elsz): Now a signed constant, not a size_t var. We prefer signed
16648 types to unsigned, to avoid integer comparison confusion. Without
16649 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16650 "cannot optimize loop, the loop counter may overflow", a symptom
16652 * indent.c (Fvertical_motion): Mark locals as initialized.
16653 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16655 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16657 * search.c (Fre_search_backward): Mention `case-fold-search' in
16658 all the re_search_* functions (bug#8138).

16681 (display_string): If we need to ignore text properties of
16682 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16683 original value of -1 will not work with bidi.)
16684 (compute_display_string_pos): First arg is now struct
16685 `text_pos *'; all callers changed. Support display properties on
16687 (compute_display_string_end): Support display properties on Lisp
16689 (init_iterator, reseat_1, reseat_to_string): Initialize the
16690 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16691 when iterating on a string not from display properties).

16693 Fix calculation of the object to scan. Fixes an error when using
16695 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16696 base_level_stop; instead, set base_level_stop to BEGV.
16697 Fixes crashes in vertical-motion.
16698 (next_element_from_buffer): Improve commentary for when
16699 the iterator is before prev_stop.
16700 (init_iterator): Initialize bidi_p from the default value of
16701 bidi-display-reordering, not from buffer-local value. Use the

16723 parts of next_element_from_buffer, next_element_from_string, and
16724 next_element_from_c_string.

16736 (get_overlay_strings_1, push_display_prop): Set up the bidi
16737 iterator for displaying display or overlay strings.
16738 (forward_to_next_line_start): Don't use the shortcut if
16740 (back_to_previous_visible_line_start): If handle_display_prop
16741 pushed the iterator stack, restore the internal state of the bidi
16742 iterator by calling bidi_pop_it same number of times.
16743 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16744 and we are bidi-iterating, don't decrement the iterator position;
16745 instead, set the first_elt flag in the bidi iterator, to produce
16747 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16748 (push_display_prop): xassert that we are iterating a buffer.
16749 (push_it, pop_it): Save and restore paragraph_embedding member.
16750 (handle_single_display_spec, next_overlay_string)
16751 (get_overlay_strings_1, reseat_1, reseat_to_string)
16752 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16753 correctly. Don't assume unibyte strings are not bidi-reordered.

16762 property. Fix a typo in popping stretch info. Add an assertion
16763 for verifying that the iterator position is in sync with the bidi
16765 (handle_single_display_spec, get_overlay_strings_1)

16790 displayed in margins. (Bug#8133) (Bug#8867)
16791 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

16819 changed to -1 and -2, respectively.
16820 (bidi_char_at_pos): New function.
16821 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16913 In theory, the old code could also have corrupted Emacs internals,
16914 though it'd be very unlikely.

17181 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17219 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17220 subseconds part to the entropy, as that's a bit more random.
17221 Prefer signed to unsigned, since the signedness doesn't matter and
17222 in general we prefer signed. When given a limit, use a
17223 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17224 latter isn't right if USE_2_TAGS_FOR_INTS.
17225 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17226 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17239 This is more efficient than Ffile_directory_p and avoids a minor race.

17243 * buffer.c (Foverlay_put): Say what the return value is

17250 error be more correct.

17269 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

17366 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
17369 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
17371 * eval.c (struct backtrace): Simplify and port the data structure.
17372 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17373 signed bit field, as this assumption is not portable and it makes
17374 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17375 "char debug_on_exit : 1" as this is not portable either; instead,
17376 use the portable "unsigned int debug_on_exit : 1". Remove unused
17377 member evalargs. Remove obsolete comments about cc bombing out.
17379 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17447 (emacs_fixed_new): Set priv->f to argument.
17448 (emacs_fixed_get_preferred_width)
17449 (emacs_fixed_get_preferred_height): Use min_width/height from
17450 frames size_hint to set minimum and natural (Bug#8919).
17451 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17452 and use min_width/height from frames size_hint to set
17453 min_width/height (Bug#8919).

17473 Use gnulib's dup2 module instead of rolling our own.
17474 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17476 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17478 * dispnew.c (scrolling_window): Before scrolling, turn off a

17541 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17543 Integer and buffer overflow fixes (Bug#8873).
17545 * print.c (printchar, strout): Check for string overflow.
17546 (PRINTPREPARE, printchar, strout):
17547 Don't set size unless allocation succeeds.
17549 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17550 for sizes. Check for string overflow more accurately.
17551 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17553 * macros.c: Integer and buffer overflow fixes.
17554 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17555 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17556 Use ptrdiff_t, not int, for sizes.

17558 Check for size-calculation overflow.
17559 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17561 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17563 * lread.c: Integer overflow fixes.
17564 (read_integer): Radix is now EMACS_INT, not int,
17565 to improve quality of diagnostics for out-of-range radices.
17566 Calculate buffer size correctly for out-of-range radices.
17567 (read1): Check for integer overflow in radices, and in
17568 read-circle numbers.
17569 (read_escape): Avoid int overflow.
17570 (Fload, openp, read_buffer_size, read1)
17571 (substitute_object_recurse, read_vector, read_list, map_obarray):
17572 Use ptrdiff_t, not int, for sizes.

17587 2011-06-22 Leo Liu <sdl.web@gmail.com>
17589 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17590 Move to minibuffer.el.
17592 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17594 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17595 The following patches are for when GLYPH_DEBUG && !XASSERT.
17596 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17597 * dispnew.c (flush_stdout):
17598 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17599 Mark as externally visible.
17600 * dispnew.c (check_window_matrix_pointers): Now static.
17601 * dispnew.c (window_to_frame_vpos):
17602 * xfns.c (unwind_create_frame):
17603 * xterm.c (x_check_font): Remove unused local.
17604 * scroll.c (CHECK_BOUNDS):
17605 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17606 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17607 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17608 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17609 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17611 (debug_method_add): Use va_list and vsprintf rather than relying
17612 on undefined behavior with wrong number of arguments.
17613 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17614 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17615 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17616 since we're not interested in debugging glyphs with old libraries.
17617 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17618 GCC 4.6.0's static checking.
17620 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17622 Integer overflow and signedness fixes (Bug#8873).

17632 (x_create_bitmap_from_xpm_data):
17633 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17634 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17636 * xfaces.c (load_pixmap):
17637 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17638 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17639 (.bitmaps_last, struct x_output.icon_bitmap):
17640 Use ptrdiff_t, not int, for bitmap indexes.
17641 (x_allocate_bitmap_record): Check for size overflow.
17642 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17644 Use ptrdiff_t, not int, for overlay counts.
17645 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17646 * editfns.c (overlays_around, get_pos_property):
17647 * textprop.c (get_char_property_and_overlay):
17648 * xdisp.c (next_overlay_change, note_mouse_highlight):
17649 * xfaces.c (face_at_buffer_position):
17650 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17651 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17652 (Fnext_overlay_change, Fprevious_overlay_change)
17653 (mouse_face_overlay_overlaps, Foverlays_in):
17654 Use ptrdiff_t, not int, for sizes.
17655 (overlays_at, overlays_in): Check for size-calculation overflow.
17657 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17659 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17660 (x_session_initialize): Do not assume string length fits in int.
17662 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17663 This is unlikely, but can occur if DPI is outlandish.
17665 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17666 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17668 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17669 * xrdb.c (magic_file_p, search_magic_path):
17670 Omit last arg SUFFIX; it was always 0. All callers changed.
17671 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17673 * xfont.c (xfont_match): Avoid need for strlen.
17675 * xfns.c: Don't assume strlen fits in int.
17676 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17678 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17679 not unsigned long, as we prefer signed integers. All callers changed.
17680 Detect integer overflow in repeat count.
17681 (message_dolog): Don't assume print length fits in 39 bytes.
17682 (display_mode_element): Don't assume strlen fits in int.
17684 * termcap.c: Don't assume sizes fit in int and never overflow.
17685 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17686 (gobble_line): Check for size-calculation overflow.
17688 * minibuf.c (Fread_buffer):
17689 * lread.c (intern, intern_c_string):
17690 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17691 Don't assume string length fits in int.

17700 Don't assume integer property fits in fixnum.
17701 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17703 * filelock.c: Fix some buffer overrun and integer overflow issues.
17704 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17705 Reformulate so as not to need the command string.
17706 Invoke gzip -cd rather than gunzip, as it's more portable.
17707 (lock_info_type, lock_file_1, lock_file):
17708 Don't assume pid_t and time_t fit in unsigned long.
17709 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17710 (current_lock_owner): Prefer signed type for sizes.
17711 Use memcpy, not strncpy, where memcpy is what is really wanted.
17712 Don't assume (via atoi) that time_t and pid_t fit in int.
17713 Check for time_t and/or pid_t out of range, e.g., via a network share.
17714 Don't alloca where an auto var works fine.
17716 * fileio.c: Fix some integer overflow issues.
17717 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17718 Don't assume string length fits in int.
17719 (directory_file_name): Don't assume string length fits in long.
17720 (make_temp_name): Don't assume pid fits in int, or that its print
17721 length is less than 20.
17723 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17725 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17727 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17729 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17730 We prefer signed integers, even for size calculations.
17732 * emacs.c: Don't assume string length fits in 'int'.
17733 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17734 (main): Don't invoke strlen when not needed.

17739 * callproc.c (getenv_internal_1, getenv_internal)
17740 (Fgetenv_internal):
17741 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17743 * lread.c (invalid_syntax): Omit length argument.
17744 All uses changed. This doesn't fix a bug, but it simplifies the
17745 code away from its former Hollerith-constant appearance, and it's
17746 one less 'int' to worry about when looking at integer-overflow issues.
17747 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17749 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17750 This didn't break anything, but it didn't help either.
17751 It's confusing to put a bogus integer in a place where the actual
17752 value does not matter.
17753 (LIST_END_P): Remove unused macro and its bogus comment.
17754 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17756 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17757 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17759 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17760 We prefer signed types, and the value cannot exceed the EMACS_INT
17761 range anyway (because otherwise the length would not be representable).
17762 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17763 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17764 This avoids a GCC warning when WIDE_EMACS_INT.
17766 * indent.c (sane_tab_width): New function.
17767 (current_column, scan_for_column, Findent_to, position_indentation)
17768 (compute_motion): Use it. This is just for clarity.
17769 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17771 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17773 * lisp.h (lint_assume): New macro.
17774 * composite.c (composition_gstring_put_cache):
17775 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17777 * editfns.c, insdel.c:
17778 Omit unnecessary forward decls, to simplify future changes.
17780 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17782 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17784 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17785 Use much-faster test for byte-length change.
17786 Don't assume string byte-length fits in 'int'.
17787 Check that character arg fits in 'int'.
17788 (mapcar1): Declare byte as byte, for clarity.
17790 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17792 * fns.c (concat): Catch string overflow earlier.
17793 Do not rely on integer wraparound.
17795 * dispextern.h (struct it.overlay_strings_charpos)
17796 (struct it.selective): Now EMACS_INT, not int.
17797 * xdisp.c (forward_to_next_line_start)
17798 (back_to_previous_visible_line_start)
17799 (reseat_at_next_visible_line_start, next_element_from_buffer):
17800 Don't arbitrarily truncate the value of 'selective' to int.
17802 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17804 * composite.c: Don't truncate sizes to 'int'.
17805 (composition_gstring_p, composition_reseat_it)
17806 (composition_adjust_point): Use EMACS_INT, not int.
17807 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17808 not EMACS_UINT, for indexes.
17810 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17812 * buffer.c: Include <verify.h>.
17813 (struct sortvec.priority, struct sortstr.priority):
17814 Now EMACS_INT, not int.
17815 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17816 (struct sortstr.size, record_overlay_string)
17817 (struct sortstrlist.size, struct sortlist.used):
17818 Don't truncate size to int.
17819 (record_overlay_string): Check for size-calculation overflow.
17820 (init_buffer_once): Check at compile-time, not run-time.
17822 2011-06-22 Jim Meyering <meyering@redhat.com>
17824 Don't leak an XBM-image-sized buffer
17825 * image.c (xbm_load): Free the image buffer after using it.
17827 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17830 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17831 that Sun C diagnosed.
17832 * fns.c (secure_hash): Fix pointer signedness issue.
17833 * intervals.c (static_offset_intervals): New function.
17834 (offset_intervals): Use it.
17836 2011-06-21 Leo Liu <sdl.web@gmail.com>
17839 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17842 * fns.c (secure_hash): Rename from crypto_hash_function and change
17843 the first arg to accept symbols.
17844 (Fsecure_hash): New primitive.
17845 (syms_of_fns): New symbols.
17847 2011-06-20 Deniz Dogan <deniz@dogan.se>
17849 * process.c (Fset_process_buffer): Clarify return value in
17852 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17854 * dispnew.c (add_window_display_history): Use BVAR.
17856 * xdisp.c (debug_method_add): Use BVAR.
17857 (check_window_end, dump_glyph_matrix, dump_glyph)
17858 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17860 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17863 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17864 check till after the cache is created in init_frame_faces.
17866 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17868 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17870 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17872 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17873 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17874 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17876 Improve buffer-overflow checking (Bug#8873).
17877 * fileio.c (Finsert_file_contents):
17878 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17879 Remove the old (too-loose) buffer overflow checks.
17880 They weren't needed, since make_gap checks for buffer overflow.
17881 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17882 The old code merely checked for Emacs fixnum overflow, and relied
17883 on undefined (wraparound) behavior. The new code avoids undefined
17884 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17886 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17887 Tune. Don't use wider integers than needed. Don't use alloca.
17888 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17890 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17892 * insdel.c, lisp.h (buffer_overflow): New function.
17893 (insert_from_buffer_1, replace_range, replace_range_2):
17894 * insdel.c (make_gap_larger):
17895 * editfns.c (Finsert_char):
17896 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17898 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17900 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17902 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17904 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17905 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17907 * fileio.c: Don't assume EMACS_INT fits in off_t.
17908 (emacs_lseek): New static function.
17909 (Finsert_file_contents, Fwrite_region): Use it.
17910 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17912 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17914 * fns.c: Don't overflow int when computing a list length.
17915 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17916 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17917 truncation on 64-bit hosts. Check for QUIT every
17918 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17919 faster and is responsive enough.
17920 (Flength): Report an error instead of overflowing an integer.
17921 (Fsafe_length): Return a float if the value is not representable
17922 as a fixnum. This shouldn't happen except in contrived situations.
17923 (Fnthcdr, Fsort): Don't assume list length fits in int.
17924 (Fcopy_sequence): Don't assume vector length fits in int.
17926 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17927 (header_size, word_size): New constants.
17928 (allocate_vectorlike): Don't check size overflow here.
17929 (allocate_vector): Check it here instead, since this is the only
17930 caller of allocate_vectorlike that could cause overflow.
17931 Check that the new vector's length is representable as a fixnum.
17933 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17934 The previous code was bogus. For example, next_almost_prime (32)
17935 returned 39, which is undesirable as it is a multiple of 3; and
17936 next_almost_prime (24) returned 25, which is a multiple of 5 so
17937 why was the code bothering to check for multiples of 7?
17939 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17941 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17943 Variadic C functions now count arguments with ptrdiff_t.
17944 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17945 Back then I didn't know that the Emacs coding style prefers signed int.
17946 Also, in the meantime I found a few more instances where arguments
17947 were being counted with int, which may truncate counts on 64-bit
17948 machines, or EMACS_INT, which may be unnecessarily wide.
17949 * lisp.h (struct Lisp_Subr.function.aMANY)
17950 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17951 Arg counts are now ptrdiff_t, not size_t.
17952 All variadic functions and their callers changed accordingly.
17953 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17954 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17955 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17956 * callint.c (Fcall_interactively): Check arg count for overflow,
17957 to avoid potential buffer overrun. Use signed char, not 'int',
17958 for 'varies' array, so that we needn't bother to check its size
17959 calculation for overflow.
17960 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17961 * eval.c (apply_lambda):
17962 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17963 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17964 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17966 * callint.c (Fcall_interactively): Don't use index var as event count.
17968 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17969 * mem-limits.h (SIZE): Remove; no longer used.
17971 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17973 Remove unnecessary casts.
17974 * xterm.c (x_term_init):
17975 * xfns.c (x_set_border_pixel):
17976 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17977 These aren't needed now that we assume ANSI C.
17979 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17980 It's more likely to cause problems (due to unsigned overflow)
17983 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17985 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17987 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17989 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17991 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17993 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17995 GLYPH_CODE_FACE returns EMACS_INT, not int.
17996 * dispextern.h (merge_faces):
17997 * xfaces.c (merge_faces):
17998 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17999 Don't assume EMACS_INT fits in int.
18001 * character.h (CHAR_VALID_P): Remove unused parameter.
18002 * fontset.c, lisp.h, xdisp.c: All uses changed.
18004 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18006 * fns.c (concat): Minor tuning based on overflow analysis.
18007 This doesn't fix any bugs. Use int to hold character, instead
18008 of constantly refetching from Emacs object. Use XFASTINT, not
18009 XINT, for value known to be a character. Don't bother comparing
18010 a single byte to 0400, as it's always less.
18012 * floatfns.c (Fexpt):
18013 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18015 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18018 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18020 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18021 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18022 incorrectly succeed when S was a string, because 4294967386 was
18023 truncated before it was used.
18025 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18026 Otherwise, an out-of-range integer could cause undefined behavior
18029 * composite.c: Use int, not EMACS_INT, for characters.
18030 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18031 EMACS_INT, for values that are known to be in character range.
18032 This doesn't fix any bugs but is the usual style inside Emacs and
18033 may generate better code on 32-bit machines.
18035 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18036 This is for reasons similar to the recent CHAR_STRING fix.
18037 * charset.c (Fencode_char): Check that character arg is actually
18038 a character. Pass an int to ENCODE_CHAR.
18039 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18040 wider than 'int', as a compile-time check to prevent future regressions
18043 * character.c (char_string): Remove unnecessary casts.
18045 Make sure a 64-bit char is never passed to CHAR_STRING.
18046 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18047 by silently ignoring the top 32 bits, allowing some values
18048 that were far too large to be valid characters.
18049 * character.h: Include <verify.h>.
18050 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18051 arguments are no wider than unsigned, as a compile-time check
18052 to prevent future regressions in this area.
18054 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18055 (Fsubst_char_in_region):
18057 * xdisp.c (decode_mode_spec_coding):
18058 Adjust to CHAR_STRING's new requirement.
18059 * editfns.c (Finsert_char, Fsubst_char_in_region):
18060 * fns.c (concat): Check that character args are actually
18061 characters. Without this test, these functions did the wrong
18062 thing with wildly out-of-range values on 64-bit hosts.
18064 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18065 These casts should not be needed on 32-bit hosts, either.
18066 * keyboard.c (read_char):
18067 * lread.c (Fload): Remove casts to unsigned.
18069 * lisp.h (UNSIGNED_CMP): New macro.
18070 This fixes comparison bugs on 64-bit hosts.
18071 (ASCII_CHAR_P): Use it.
18072 * casefiddle.c (casify_object):
18073 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18074 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18075 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18076 * dispextern.h (FACE_FROM_ID):
18077 * keyboard.c (read_char): Use UNSIGNED_CMP.
18079 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18080 not to EMACS_INT, to avoid GCC warning.
18082 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18084 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18085 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18086 isn't needed on 32-bit machines.
18088 * buffer.c (Fgenerate_new_buffer_name):
18089 Use EMACS_INT for count, not int.
18090 (advance_to_char_boundary): Return EMACS_INT, not int.
18092 * data.c (Qcompiled_function): Now static.
18094 * window.c (window_body_lines): Now static.
18096 * image.c (gif_load): Rename local to avoid shadowing.
18098 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18099 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18100 * alloc.c (make_save_value): Integer argument is now of type
18101 ptrdiff_t, not int.
18102 (mark_object): Use ptrdiff_t, not int.
18103 * lisp.h (pD): New macro.
18104 * print.c (print_object): Use it.
18106 * alloc.c: Use EMACS_INT, not int, to count objects.
18107 (total_conses, total_markers, total_symbols, total_vector_size)
18108 (total_free_conses, total_free_markers, total_free_symbols)
18109 (total_free_floats, total_floats, total_free_intervals)
18110 (total_intervals, total_strings, total_free_strings):
18111 Now EMACS_INT, not int. All uses changed.
18112 (Fgarbage_collect): Compute overall total using a double, so that
18113 integer overflow is less likely to be a problem. Check for overflow
18114 when converting back to an integer.
18115 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18116 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18117 These were 'int' variables that could overflow on 64-bit hosts;
18118 they were never used, so remove them instead of repairing them.
18119 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18120 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18121 Previously, this ceilinged at INT_MAX, but that doesn't work on
18123 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18125 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18126 (allocate_vectorlike): Check for ptrdiff_t overflow.
18127 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18128 when a (possibly-narrower) signed value would do just as well.
18129 We prefer using signed arithmetic, to avoid comparison confusion.
18131 * alloc.c: Catch some string size overflows that we were missing.
18132 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18133 for convenience in STRING_BYTES_MAX.
18134 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18135 The definition here is exact; the one in lisp.h was approximate.
18136 (allocate_string_data): Check for string overflow. This catches
18137 some instances we weren't catching before. Also, it catches
18138 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18139 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18140 and ptrdiff_t and EMACS_INT are both 64 bits.
18142 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18143 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18144 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18146 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18148 * alloc.c (Fmake_string): Check for out-of-range init.
18150 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18152 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18154 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18156 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18157 xg_get_default_scrollbar_width.
18159 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18160 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18161 (style_changed_cb): Call update_theme_scrollbar_width and call
18162 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18163 all frames (Bug#8505).
18164 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18165 Call gtk_window_set_resizable if HAVE_GTK3.
18166 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18167 and height if HAVE_GTK3 (Bug#8505).
18168 (scroll_bar_width_for_theme): New variable.
18169 (update_theme_scrollbar_width): New function.
18170 (xg_get_default_scrollbar_width): Move code to
18171 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18172 (xg_initialize): Call update_theme_scrollbar_width.
18174 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18176 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18178 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18180 * frame.c (make_frame): Call other_buffer_safely instead of
18183 * window.c (temp_output_buffer_show): Call display_buffer with
18184 second argument Vtemp_buffer_show_specifiers and reset latter
18185 immediately after the call.
18186 (Vtemp_buffer_show_specifiers): New variable.
18187 (auto_window_vscroll_p, next_screen_context_lines)
18188 (Vscroll_preserve_screen_position): Remove leading asterisks from
18191 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18193 Fix minor problems found by GCC 4.6.0 static checking.
18194 * buffer.c (Qclone_number): Remove for now, as it's unused.
18195 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18196 (record_buffer): Remove unused local.
18197 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18198 (set_frame_buffer_list): Remove; unused.
18199 * frame.h (other_visible_frames): Remove decl.
18200 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18201 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18202 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18204 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18205 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18206 Define only if HAVE_GPM.
18207 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18208 (update_hints_inhibit): Remove; never set. All uses removed.
18209 * widgetprv.h (emacsFrameClassRec): Remove decl.
18210 * window.c (delete_deletable_window): Now returns void, since it
18211 wasn't returning anything.
18212 (compare_window_configurations): Remove unused locals.
18213 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18214 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18215 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18216 the same widths as pointers. This follows up on the 2011-05-06 patch.
18217 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18218 * xterm.h: Likewise.
18219 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18221 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18223 * makefile.w32-in: Update dependencies.
18224 (LISP_H): Add lib/intprops.h.
18226 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18228 * image.c (gif_load): Add animation frame delay to the metadata.

18684 Obey Vx_select_enable_clipboard_manager. Catch errors in
18685 x_clipboard_manager_save (Bug#8779).
18686 (Vx_select_enable_clipboard_manager): New variable.
18687 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18689 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18691 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18693 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18695 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18696 in the current matrix if keep_current_p is non-zero.
18698 2011-06-04 Eli Zaretskii <eliz@gnu.org>
18700 * bidi.c (bidi_level_of_next_char): Fix last change.
18702 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18704 Support bidi reordering of text covered by display properties.
18706 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18707 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18708 (bidi_cache_search, bidi_cache_iterator_state)
18709 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18710 (bidi_level_of_next_char, bidi_move_to_visually_next):
18711 Support character positions inside a run of characters covered by a
18713 (bidi_paragraph_init, bidi_resolve_explicit_1)
18714 (bidi_level_of_next_char): Call bidi_fetch_char and
18715 bidi_fetch_char_advance instead of FETCH_CHAR and
18716 FETCH_CHAR_ADVANCE.
18717 (bidi_init_it): Initialize new members.
18718 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18720 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18721 instead of using explicit *_CHAR codes.
18722 (bidi_resolve_explicit, bidi_resolve_weak):
18723 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18724 bidirectional text is supported only in multibyte buffers.
18725 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18726 it to initialize the frame_window_p member of struct bidi_it.
18727 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18728 (bidi_resolve_explicit, bidi_resolve_weak)
18729 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
18730 bidi_it->nchars is non-positive.
18731 (bidi_level_of_next_char): Don't try to lookup the cache for the
18732 next/previous character if nothing is cached there yet, or if we
18733 were just reseat()'ed to a new position.
18735 * xdisp.c (set_cursor_from_row): Set start and stop points
18736 according to the row's direction when priming the loop that looks
18737 for the glyph on which to display cursor.
18738 (single_display_spec_intangible_p): Function deleted.
18739 (display_prop_intangible_p): Reimplement to call
18740 handle_display_spec instead of single_display_spec_intangible_p.
18741 Accept 3 additional arguments needed by handle_display_spec.
18742 This fixes incorrect cursor motion across display property with complex
18743 values: lists, `(when COND...)' forms, etc.
18744 (single_display_spec_string_p): Support property values that are
18745 lists with the argument STRING its top-level element.
18746 (display_prop_string_p): Fix the condition for processing a
18747 property that is a list to be consistent with handle_display_spec.
18748 (handle_display_spec): New function, refactored from the
18749 last portion of handle_display_prop.
18750 (compute_display_string_pos): Accept additional argument
18751 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18752 value of a `display' property is a "replacing spec".
18753 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18754 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18755 the display property, but just return a value indicating whether
18756 the display property will replace the characters it covers.
18757 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18758 frame_window_p members of struct bidi_it.
18759 (compute_display_string_pos, compute_display_string_end):
18761 (push_it): Accept second argument POSITION, where pop_it should
18762 jump to continue iteration.
18763 (reseat_1): Initialize bidi_it.disp_pos.
18765 * keyboard.c (adjust_point_for_property): Adjust the call to
18766 display_prop_intangible_p to its new signature.
18768 * dispextern.h (struct bidi_it): New member frame_window_p.
18769 (bidi_init_it): Update prototypes.
18770 (display_prop_intangible_p): Update prototype.
18771 (compute_display_string_pos, compute_display_string_end):
18772 Declare prototypes.
18773 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18776 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18778 Malloc failure behavior now depends on size of allocation.
18779 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18780 * lisp.h: Change signatures accordingly.
18781 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18782 All callers changed. (Bug#8762)
18784 * gnutls.c: Use Emacs's memory allocators.
18785 Without this change, the gnutls library would invoke malloc etc.
18786 directly, which causes problems on non-SYNC_INPUT hosts, and which
18787 runs afoul of improving memory_full behavior. (Bug#8761)
18788 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18789 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18790 xfree instead of the default malloc, realloc, free.
18791 (Fgnutls_boot): No need to check for memory allocation failure,
18792 since xmalloc does that for us.
18794 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18795 * category.c (hash_get_category_set):
18796 * ccl.c (ccl_driver):
18797 * charset.c (Fdefine_charset_internal):
18798 * charset.h (struct charset.hash_index):
18799 * composite.c (get_composition_id, gstring_lookup_cache)
18800 (composition_gstring_put_cache):
18801 * composite.h (struct composition.hash_index):
18802 * dispextern.h (struct image.hash):
18803 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18804 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18805 (hashfn_equal, hashfn_user_defined, make_hash_table)
18806 (maybe_resize_hash_table, hash_lookup, hash_put)
18807 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18808 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18809 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18810 * image.c (make_image, search_image_cache, lookup_image)
18811 (xpm_put_color_table_h):
18812 * lisp.h (struct Lisp_Hash_Table):
18813 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18814 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18815 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18816 * alloc.c (allocate_vectorlike):
18817 Check for overflow in vector size calculations.
18818 * ccl.c (ccl_driver):
18819 Check for overflow when converting EMACS_INT to int.
18820 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18821 need to be updated by these changes.
18822 * fns.c (make_hash_table, maybe_resize_hash_table):
18823 Check for integer overflow with large hash tables.
18824 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18825 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18826 (SXHASH_REDUCE): New macro.
18827 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18828 Use it instead of discarding useful hash info with large hash values.
18829 (sxhash_float): New function.
18830 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18831 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18832 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18833 Rewrite to use FIXNUM_BITS, as this simplifies things.
18834 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18835 Adjust signatures to match updated version of code.
18836 (consing_since_gc): Now EMACS_INT, since a single hash table can
18837 use more than INT_MAX bytes.
18839 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18841 Make it possible to build with GCC-4.6+ -O2 -flto.
18843 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18845 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18847 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18848 Call minibuffer-inactive-mode.
18850 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18852 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18853 Update dependencies.
18855 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18857 * data.c (init_data): Remove code for UTS, this system is not
18860 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18862 Don't force ./temacs to start in terminal mode.
18864 * frame.c (make_initial_frame): Initialize faces in all cases, not
18865 only when CANNOT_DUMP is defined.
18866 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18868 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18870 * dispnew.c (add_window_display_history): Use const for the string
18871 pointer. Remove declaration, not needed.
18873 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18875 Use 'inline', not 'INLINE'.
18876 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18877 * alloc.c, fontset.c (INLINE): Remove.
18878 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18879 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18880 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18881 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18882 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18884 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18886 Make it possible to run ./temacs.
18888 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18889 syms_of_callproc does the same thing. Remove test for
18890 "initialized", do it in the caller.
18891 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18893 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18895 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18896 (read_minibuf): Use get_minibuffer.
18897 (syms_of_minibuf): Use DEFSYM.
18898 (Qmetadata): New var.
18899 * data.c (Qbuffer): Don't make it static.
18900 (syms_of_data): Use DEFSYM.
18902 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18904 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18905 (CCL_CODE_MIN): New macro.
18907 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18909 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18911 * eval.c (Qdebug): Now static.
18912 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18913 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18914 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18916 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18918 * image.c: Various fixes to ImageMagick code comments.
18919 (Fimagemagick_types): Doc fix.
18921 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18923 Minor fixes prompted by GCC 4.6.0 warnings.
18925 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18927 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18928 (x_clipboard_manager_save_all): Move extern decl to ...
18929 * xterm.h: ... here, so that it can be checked for consistency.
18931 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18933 * xselect.c (x_clipboard_manager_save_frame)
18934 (x_clipboard_manager_save_all): New functions.
18935 (Fx_clipboard_manager_save): Lisp function deleted.
18937 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18938 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18940 * xterm.h: Update prototype.
18942 2011-05-28 William Xu <william.xwl@gmail.com>
18944 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18945 exiting (Bug#8239).
18947 2011-05-28 Jim Meyering <meyering@redhat.com>
18949 Avoid a sign-extension bug in crypto_hash_function.
18950 * fns.c (to_uchar): Define.
18951 (crypto_hash_function): Use it to convert some newly-signed
18952 variables to unsigned, to avoid sign-extension bugs. For example,
18953 without this change, (md5 "truc") would evaluate to
18954 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18955 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18956 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18958 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18960 Integer overflow fixes.
18962 * dbusbind.c: Serial number integer overflow fixes.
18963 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18964 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18965 to hold a serial number that is too large for a fixnum.
18966 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18967 Check for serial numbers out of range. Decode any serial number
18968 that was so large that it became a float. (Bug#8722)
18970 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18971 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18972 Use XFASTINT rather than XUINT when numbers are nonnegative.
18973 (xd_append_arg, Fdbus_method_return_internal):
18974 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18975 arguments, check that Lisp number is nonnegative, rather than
18976 silently wrapping negative numbers around. (Bug#8722)
18977 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18980 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18982 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18984 ccl: Add integer overflow checks.
18985 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18986 (IN_INT_RANGE): New macros.
18987 (ccl_driver): Use them to check for integer overflow when
18988 decoding a CCL program. Many of the new checks are whether XINT (x)
18989 fits in int; it doesn't always, on 64-bit hosts. The new version
18990 doesn't catch all possible integer overflows, but it's an
18991 improvement. (Bug#8719)
18993 * alloc.c (make_event_array): Use XINT, not XUINT.
18994 There's no need for unsigned here.
18996 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18997 This follows up to the 2011-05-06 change that substituted uintptr_t
18998 for EMACS_INT. This case wasn't caught back then.
19000 Rework Fformat to avoid integer overflow issues.
19001 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19002 now (part of C89). Include <verify.h>.
19003 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19004 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19005 (Fformat): Avoid the prepass trying to compute sizes; it was only
19006 approximate and thus did not catch overflow reliably. Instead, walk
19007 through the format just once, formatting and computing sizes as we go,
19008 checking for integer overflow at every step, and allocating a larger
19009 buffer as needed. Keep track separately whether the format is
19010 multibyte. Keep only the most-recently calculated precision, rather
19011 than them all. Record whether each argument has been converted to
19012 string. Use EMACS_INT, not int, for byte and char and arg counts.
19013 Support field widths and precisions larger than INT_MAX. Avoid
19014 sprintf's undefined behavior with conversion specifications such as %#d
19015 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19016 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19017 formatting out-of-range floating point numbers with int
19018 formats. (Bug#8668)
19020 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19022 * data.c: Avoid integer truncation in expressions involving floats.
19023 * data.c: Include <intprops.h>.
19024 (arith_driver): When there's an integer overflow in an expression
19025 involving floating point, convert the integers to floating point
19026 so that the resulting value does not suffer from catastrophic
19027 integer truncation. For example, on a 64-bit host (* 4
19028 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19029 Do not rely on undefined behavior after integer overflow.
19031 merge count_size_as_multibyte, parse_str_to_multibyte
19032 * character.c, character.h (count_size_as_multibyte):
19033 Rename from parse_str_to_multibyte; all uses changed.
19034 Check for integer overflow.
19035 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19036 since it's now a duplicate of the other. This is more of
19037 a character than a buffer op, so better that it's in character.c.
19038 * fns.c, print.c: Adjust to above changes.
19040 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19042 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19044 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19046 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19047 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19048 (x_clipboard_manager_save): Now static.
19049 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19051 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19052 (crypto_hash_function): Now static.
19053 Fix pointer signedness problems. Avoid unnecessary initializations.
19055 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19057 * termhooks.h (Vselection_alist): Make it terminal-local.
19059 * terminal.c (create_terminal): Initialize it.
19061 * xselect.c: Support for clipboard managers.
19062 (Vselection_alist): Move to termhooks.h as terminal-local var.
19063 (LOCAL_SELECTION): New macro.
19064 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19065 (symbol_to_x_atom): Remove gratuitous arg.
19066 (x_handle_selection_request, lisp_data_to_selection_data)
19067 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19068 (x_own_selection, x_get_local_selection, x_convert_selection):
19069 New arg, specifying work frame. Use terminal-local Vselection_alist.
19070 (some_frame_on_display): Delete unused function.
19071 (Fx_own_selection_internal, Fx_get_selection_internal)
19072 (Fx_disown_selection_internal, Fx_selection_owner_p)
19073 (Fx_selection_exists_p): New optional frame arg.
19074 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19075 (x_handle_selection_clear): Don't treat other terminals with the
19076 same keyboard specially. Use the terminal-local Vselection_alist.
19077 (x_clear_frame_selections): Use Frun_hook_with_args.
19079 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19081 * xterm.h: Add support for those atoms.
19083 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19085 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19086 (converted_selections, conversion_fail_tag): New global variables.
19087 (x_selection_request_lisp_error): Free the above.
19088 (x_get_local_selection): Remove unnecessary code.
19089 (x_reply_selection_request): Args changed; handle arbitrary array
19090 of converted selections stored in converted_selections.
19091 Separate the XChangeProperty and SelectionNotify steps.
19092 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19093 (x_convert_selection): New function.
19094 (x_handle_selection_event): Simplify.
19095 (x_get_foreign_selection): Don't ignore incoming requests while
19096 waiting for an answer; this will fail when we implement
19097 SAVE_TARGETS, and seems unnecessary anyway.
19098 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19099 (Vx_sent_selection_functions): Doc fix.
19101 2011-05-26 Leo Liu <sdl.web@gmail.com>
19103 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19105 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19107 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19109 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19110 for fringe update if it has periodic bitmap.
19111 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19112 and fringe_bitmap_periodic_p.
19114 * fringe.c (get_fringe_bitmap_data): New function.
19115 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19116 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19117 row. Mark glyph row for fringe update if periodicity changed.
19119 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19120 for fringe update unless it has periodic bitmap.
19122 2011-05-25 Kenichi Handa <handa@m17n.org>
19124 * xdisp.c (get_next_display_element): Set correct it->face_id for
19125 a static composition.
19127 2011-05-24 Leo Liu <sdl.web@gmail.com>
19130 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19132 * fns.c (crypto_hash_function, Fsha1): New function.
19133 (Fmd5): Use crypto_hash_function.
19134 (syms_of_fns): Add Ssha1.
19136 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19138 * gnutls.c: Remove unused macros.
19139 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19140 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19141 Remove macros that are defined and never used.
19142 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19144 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19146 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19147 (Fx_get_selection_internal): Minor cleanup.
19148 (Fx_own_selection_internal): Rename arguments for consistency with
19151 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19153 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19155 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19157 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19159 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19161 * dispnew.c (scrolling_window): Don't exclude the case that the
19162 last enabled row in the desired matrix touches the bottom boundary.
19164 2011-05-21 Glenn Morris <rgm@gnu.org>
19166 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19167 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19168 and add some more files.
19170 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19172 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19173 report_file_error introduced by the change from 2011-05-07.
19175 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19177 * systime.h (Time): Define only if emacs is defined.
19178 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19179 where the include path doesn't have X11/X.h by default. See
19180 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19182 2011-05-20 Kenichi Handa <handa@m17n.org>
19184 * composite.c (find_automatic_composition): Fix previous change.
19186 2011-05-20 Glenn Morris <rgm@gnu.org>
19188 * lisp.mk: New file, split from Makefile.in.
19189 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19190 (shortlisp): Remove.
19191 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19193 2011-05-19 Glenn Morris <rgm@gnu.org>
19195 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19196 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19197 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19198 (lisp): Set the order to that of loadup.el.
19199 (shortlisp): Make it a copy of $lisp.
19200 (SOME_MACHINE_LISP): Remove.
19201 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19202 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19204 2011-05-18 Kenichi Handa <handa@m17n.org>
19206 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19207 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19208 (find_automatic_composition): Mostly rewrite for efficiency.
19210 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19212 * makefile.w32-in: Update dependencies.
19214 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19216 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19217 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19219 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19221 Fix some integer overflow issues, such as string length overflow.
19223 * insdel.c (count_size_as_multibyte): Check for string overflow.
19225 * character.c (lisp_string_width): Check for string overflow.
19226 Use EMACS_INT, not int, for string indexes and lengths; in
19227 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19228 the resulting string length overflows an EMACS_INT; instead,
19229 report a string overflow if no precision given. When checking for
19230 precision exhaustion, use a check that cannot possibly have
19231 integer overflow. (Bug#8675)
19232 * character.h (lisp_string_width): Adjust to new signature.
19234 * alloc.c (string_overflow): New function.
19235 (Fmake_string): Use it. This doesn't change behavior, but saves
19236 a few bytes and will simplify future changes.
19237 * character.c (string_escape_byte8): Likewise.
19238 * lisp.h (string_overflow): New decl.
19240 Fixups, following up to the user-interface timestamp change.
19241 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19242 for UI timestamps, instead of unsigned long.
19243 * msdos.c (mouse_get_pos): Likewise.
19244 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19245 * w32gui.h (Time): Define by including "systime.h" rather than by
19246 declaring it ourselves. (Bug#8664)
19248 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19249 * image.c (clear_image_cache): Likewise.
19251 * term.c (term_mouse_position): Don't assume time_t wraparound.
19253 Be more systematic about user-interface timestamps.
19254 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19255 and sometimes 'EMACS_UINT', to represent these timestamps.
19256 This change causes it to use 'Time' uniformly, as that's what X uses.
19257 This makes the code easier to follow, and makes it easier to catch
19258 integer overflow bugs such as Bug#8664.
19259 * frame.c (Fmouse_position, Fmouse_pixel_position):
19260 Use Time, not unsigned long, for user-interface timestamps.
19261 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19262 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19263 * keyboard.h (last_event_timestamp): Likewise.
19264 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19265 * menu.h (xmenu_show): Likewise.
19266 * term.c (term_mouse_position): Likewise.
19267 * termhooks.h (struct input_event.timestamp): Likewise.
19268 (struct terminal.mouse_position_hook): Likewise.
19269 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19270 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19271 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19272 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19273 what it was before.
19274 * menu.h, termhooks.h: Include "systime.h", for Time.
19276 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19277 Don't assume that the difference between two unsigned long values
19278 can fit into an integer. At this point, we know button_down_time
19279 <= event->timestamp, so the difference must be nonnegative, so
19280 there's no need to cast the result if double-click-time is
19281 nonnegative, as it should be; check that it's nonnegative, just in
19282 case. This bug is triggered when events are more than 2**31 ms
19283 apart (about 25 days). (Bug#8664)
19285 * xselect.c (last_event_timestamp): Remove duplicate decl.
19286 (x_own_selection): Remove needless cast to unsigned long.
19288 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19289 that always fit in int. Use a sentinel instead of a counter, to
19290 avoid a temp and to allay GCC's concerns about possible int overflow.
19291 * frame.h (struct frame): Use int for menu_bar_items_used
19292 instead of EMACS_INT, since it always fits in int.
19294 * menu.c (grow_menu_items): Check for int overflow.
19296 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19298 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19299 Before, the code was not consistent. These values cannot exceed
19300 2**31 - 1 so there's no need to make them unsigned.
19301 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19302 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19303 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19305 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19307 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19308 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19309 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19310 presumably because the widths might not match.
19312 * window.c (size_window): Avoid needless test at loop start.
19314 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19316 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19318 2011-05-12 Drew Adams <drew.adams@oracle.com>
19320 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19322 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19324 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19325 `width' to `bar_area_x' and `bar_area_width', respectively.
19326 (x_scroll_run): Take account of fringe background extension.
19328 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19329 Rename local vars `left' and `width' to `bar_area_x' and
19330 `bar_area_width', respectively.
19331 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19332 background extension.
19334 2011-05-10 Jim Meyering <meyering@redhat.com>
19336 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19338 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19340 * image.c (Finit_image_library): Return t for built-in image types,
19341 like pbm and xbm. (Bug#8640)
19343 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19345 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19347 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19349 * w32console.c (Fset_screen_color): Doc fix.
19350 (Fget_screen_color): New function.
19351 (syms_of_ntterm): Defsubr it.
19353 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19354 unlink the temporary file if Fcall_process didn't create it in the
19356 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19357 child process will be redirected to a file specified with `:file'.
19358 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19359 cue to call_process_cleanup not to close that handle.
19361 2011-05-07 Ben Key <bkey76@gmail.com>
19363 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19364 one of two shell specific rules, either bootstrap-temacs-CMD or
19365 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19366 to the previous implementation of the bootstrap-temacs rule.
19367 The bootstrap-temacs-CMD rule is similar to the previous
19368 implementation of the bootstrap-temacs rule except that it
19369 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19372 These changes, along with some changes to nt/configure.bat,
19373 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19374 earlier fix to add support for --cflags and --ldflags options
19375 that include quotes so that it works whether make uses cmd or
19378 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19380 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19381 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19383 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19384 a string. Handle both cases.
19385 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19386 (Fdbus_register_method): Use Qinvalid_function.
19388 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19390 * makefile.w32-in: Update dependencies.
19391 (LISP_H): Add inttypes.h and stdin.h.
19392 (PROCESS_H): Add unistd.h.
19394 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19396 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19397 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19399 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19401 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19403 * term.c (vfatal): Remove stray call to va_end.
19404 It's not needed and the C Standard doesn't allow it here anyway.
19406 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19407 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19409 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19412 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19414 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19416 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19418 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19420 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19422 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19423 * charset.c (Fdefine_charset_internal): Don't initialize
19424 charset.code_space[15]. The value was garbage, on hosts with
19425 32-bit int (Bug#8600).
19427 * lread.c (read_integer): Be more consistent with string-to-number.
19428 Use string_to_number to do the actual conversion; this avoids
19429 rounding errors and fixes some other screwups. Without this fix,
19430 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19431 (digit_to_number): Move earlier, for benefit of read_integer.
19432 Return -1 if the digit is out of range for the base, -2 if it is
19433 not a digit in any supported base. (Bug#8602)
19435 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19437 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19438 to match comment at start of function. This also removes a
19439 GCC warning about overflow in a 32+64-bit port.
19441 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19443 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19444 Reported by Stefan Monnier in
19445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19446 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19447 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19449 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19450 (EMACS_UINTPTR): Likewise, with uintptr_t.
19452 * lisp.h: Prefer 64-bit EMACS_INT if available.
19453 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19454 on 32-bit hosts that have 64-bit int, so that they can access
19456 However, temporarily disable this change unless the temporary
19457 symbol WIDE_EMACS_INT is defined.
19459 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19461 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19462 This removes an assumption that EMACS_INT and long are the same
19463 width as pointers. The assumption is true for Emacs porting targets
19464 now, but we want to make other targets possible.
19465 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19466 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19467 In the rest of the code, change types of integers that hold casted
19468 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19469 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19470 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19471 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19472 No need to cast type when ORing.
19473 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19474 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19475 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19476 assume EMACS_INT is the same width as char *.
19477 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19478 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19479 Remove no-longer-needed casts.
19480 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19481 (xg_tool_bar_help_callback, xg_make_tool_item):
19482 Use EMACS_INTPTR to hold an integer
19483 that will be cast to void *; this can avoid a GCC warning
19484 if EMACS_INT is not the same width as void *.
19485 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19486 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19487 (current_message_1, set_message_1):
19488 Use a local to convert to proper width without a cast.
19489 * xmenu.c (dialog_selection_callback): Likewise.
19491 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19492 Also, don't assume VALBITS / RAND_BITS is less than 5,
19493 and don't rely on undefined behavior when shifting a 1 left into
19495 * lisp.h (get_random): Change signature to match.
19497 * lread.c (hash_string): Use size_t, not int, for hash computation.
19498 Normally we prefer signed values; but hashing is special, because
19499 it's better to use unsigned division on hash table sizes so that
19500 the remainder is nonnegative. Also, size_t is the natural width
19501 for hashing into memory. The previous code used 'int', which doesn't
19502 retain enough info to hash well into very large tables.
19503 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19505 * dbusbind.c: Don't possibly lose pointer info when converting.
19506 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19507 Use XPNTR rather than XHASH, so that the high-order bits of
19508 the pointer aren't lost when converting through void *.
19510 * eval.c (Fautoload): Don't double-shift a pointer.
19512 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19514 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19516 * gnutls.c (DEF_GNUTLS_FN):
19517 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19519 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19521 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19524 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19526 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19527 New version that can reserve upto 2GB of heap space.
19529 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19531 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19533 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19535 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to

19595 * process.c: Include lisp.h before w32.h, not after.
19596 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19597 instead of gnutls_record_check_pending.
19599 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19601 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19603 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

19649 rather than `XVECTOR (FOO)->size'.
19651 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19652 inttypes.h, as a gnulib replacement is used if it not available in
19655 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19657 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

19667 charbuf for the composition carryover bytes.
19669 2011-04-21 Eli Zaretskii <eliz@gnu.org>

19672 aborting when %lld or %lll format is passed.
19673 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19674 %llo or %llx format is passed. (Bug#8545)
19676 * window.c (window_scroll_line_based): Use a marker instead of
19677 simple variables to record original value of point. (Bug#7952)
19679 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19680 produced by %s or %c overflows available buffer space. (Bug#8545)
19682 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19684 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19685 (SIZE_MAX): Move defn after all includes, as they might #define it.
19687 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19689 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19691 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19693 * keyboard.c (Qdelayed_warnings_hook): Define.
19694 (command_loop_1): Run `delayed-warnings-hook'
19695 if Vdelayed_warnings_list is non-nil.
19696 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19697 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19699 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19701 * doprnt.c (doprnt): Don't return value smaller than the buffer
19702 size if the message was truncated. (Bug#8545).
19704 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19706 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19707 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19709 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19711 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19713 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19715 * makefile.w32-in: Update dependencies.
19717 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19719 Improve `doprnt' and its usage. (Bug#8545)
19720 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19721 `format_end'. Remove support for %l as a conversion specifier.
19722 Don't use xrealloc. Improve diagnostics when the %l size modifier
19723 is used. Update the commentary.
19725 * eval.c (verror): Simplify calculation of size_t.
19727 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19730 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19732 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19735 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19737 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19738 This makes this file independent of the recent pseudovector change.
19740 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19742 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19744 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19745 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19746 Remove unused local.
19747 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19749 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19750 GCC 4.6.0 optimizes based on type-based alias analysis.
19751 For example, if b is of type struct buffer * and v of type struct
19752 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19753 != &v->size, and therefore "v->size = 1; b->size = 2; return
19754 v->size;" must therefore return 1. This assumption is incorrect
19755 for Emacs, since it type-puns struct Lisp_Vector * with many other
19756 types. To fix this problem, this patch adds a new type struct
19757 vectorlike_header that documents the constraints on layout of vectors
19758 and pseudovectors, and helps optimizing compilers not get fooled
19759 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19760 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19761 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19763 (XSETPVECTYPE): Rewrite in terms of new macro.
19764 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19765 This is a bit clearer, and further avoids the possibility of
19766 undesirable aliasing.
19767 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19768 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19769 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19770 since Lisp_Subr is a special case (no "next" field).
19771 (ASIZE): Now uses header.size rather than size.
19772 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19773 to avoid the hassle of writing XVECTOR (foo)->header.size.
19774 (struct vectorlike_header): New type.
19775 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19776 object, to help avoid aliasing.
19777 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19778 (SUBRP): Likewise, since Lisp_Subr is a special case.
19779 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19780 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19781 (struct Lisp_Hash_Table): Combine first two members into a single
19782 struct vectorlike_header member. All uses of "size" and "next" members
19783 changed to be "header.size" and "header.next".
19784 * buffer.h (struct buffer): Likewise.
19785 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19786 * frame.h (struct frame): Likewise.
19787 * process.h (struct Lisp_Process): Likewise.
19788 * termhooks.h (struct terminal): Likewise.
19789 * window.c (struct save_window_data, struct saved_window): Likewise.
19790 * window.h (struct window): Likewise.
19791 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19792 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19793 * buffer.c (init_buffer_once): Likewise.
19794 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19796 * process.c (Fformat_network_address): Use local var for size,
19799 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19801 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19802 * data.c (atof): Remove decl; no longer used or needed.
19803 (digit_to_number): Move to lread.c.
19804 (Fstring_to_number): Use new string_to_number function, to be
19805 consistent with how the Lisp reader treats infinities and NaNs.
19806 Do not assume that floating-point numbers represent EMACS_INT
19807 without losing information; this is not true on most 64-bit hosts.
19808 Avoid double-rounding errors, by insisting on integers when
19809 parsing non-base-10 numbers, as the documentation specifies.
19810 * lisp.h (string_to_number): New decl, replacing ...
19811 (isfloat_string): Remove.
19812 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19813 (read1): Do not accept +. and -. as integers; this
19814 appears to have been a coding error. Similarly, do not accept
19815 strings like +-1e0 as floating point numbers. Do not report
19816 overflow for integer overflows unless the base is not 10 which
19817 means we have no simple and reliable way to continue.
19818 Break out the floating-point parsing into a new
19819 function string_to_number, so that Fstring_to_number parses
19820 floating point numbers consistently with the Lisp reader.
19821 (digit_to_number): Move here from data.c. Make it static inline.
19822 (E_CHAR, EXP_INT): Remove, replacing with ...
19823 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19824 (string_to_number): New function, replacing isfloat_string.
19825 This function checks for valid syntax and produces the resulting
19826 Lisp float number too. Rework it so that string-to-number
19827 no longer mishandles examples like "1.0e+". Use strtoumax,
19828 so that overflow for non-base-10 numbers is reported only when
19829 there's no portable and simple way to convert to floating point.
19831 * textprop.c (set_text_properties_1): Rewrite for clarity,
19832 and to avoid GCC warning about integer overflow.
19834 * intervals.h (struct interval): Use EMACS_INT for members
19835 where EMACS_UINT might cause problems. See
19836 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19837 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19838 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19840 (offset_intervals): Tell GCC not to worry about length overflow
19841 when negating a negative length.
19843 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19844 (overrun_check_free): Likewise.
19846 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19847 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19850 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19851 (gnutls_make_error): Rename local to avoid shadowing.
19852 (gnutls_emacs_global_deinit): ifdef out; not used.
19853 (Fgnutls_boot): Use const for pointer to readonly storage.
19854 Comment out unused local. Fix pointer signedness problems.
19856 * lread.c (openp): Don't stuff size_t into an 'int'.
19857 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19858 about possible signed overflow.
19860 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19861 (GDK_KEY_g): Don't define if already defined.
19862 (xg_prepare_tooltip): Avoid pointer signedness problem.
19863 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19865 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19866 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19868 * xfns.c (Fx_window_property): Simplify a bit,
19869 to make a bit faster and to avoid GCC 4.6.0 warning.
19870 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19872 * fns.c (internal_equal): Don't assume size_t fits in int.
19874 * alloc.c (compact_small_strings): Tighten assertion a little.
19876 Replace pEd with more-general pI, and fix some printf arg casts.
19877 * lisp.h (pI): New macro, generalizing old pEd macro to other
19878 conversion specifiers. For example, use "...%"pI"d..." rather
19879 than "...%"pEd"...".
19880 (pEd): Remove. All uses replaced with similar uses of pI.
19881 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19882 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19883 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19884 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19885 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19886 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19887 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19889 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19890 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19891 * print.c (safe_debug_print, print_object): Likewise.
19892 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19894 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19895 avoiding the 0 flag, which is not portable.
19896 * process.c (Fmake_network_process): Use pI to avoid cast.
19897 * region-cache.c (pp_cache): Likewise.
19898 * xdisp.c (decode_mode_spec): Likewise.
19899 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19900 behavior on 64-bit hosts with printf arg.
19901 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19902 (x_stop_queuing_selection_requests): Likewise.
19903 (x_get_window_property): Don't truncate byte count to an 'int'
19906 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19907 here, since it parses constructs like leading '-' and spaces,
19908 which are not wanted; and it overflows with large numbers.
19909 Instead, simply match F[0-9]+, which is what is wanted anyway.
19911 * alloc.c: Remove unportable assumptions about struct layout.
19912 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19913 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19914 (allocate_vectorlike, make_pure_vector): Use the new macros,
19915 plus offsetof, to remove unportable assumptions about struct layout.
19916 These assumptions hold on all porting targets that I know of, but
19917 they are not guaranteed, they're easy to remove, and removing them
19918 makes further changes easier.
19920 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19921 This doesn't fix a bug but makes the code clearer.
19922 (string_overrun_cookie): Now const. Use initializers that
19923 don't formally overflow signed char, to avoid warnings.
19924 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19925 can cause Emacs to crash when string overrun checking is enabled.
19926 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19927 multiple of sizeof (EMACS_INT); it need not be, if
19928 alignof(EMACS_INT) < sizeof (EMACS_INT).
19929 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19931 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19933 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19935 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19937 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19938 supposed to be handshaking. (Bug#8556)
19939 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19941 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19943 * lisp.h (Qdebug): List symbol.
19944 * eval.c (Qdebug): Restore global linkage.
19945 * keyboard.c (debug-on-event): New variable.
19946 (handle_user_signal): Break into debugger when debug-on-event
19947 matches the current signal symbol.
19949 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>

20702 to see whether these functions can be called from other modules.
20703 DEFUN now defines a static function. To make the function external
20704 so that it can be used in other C modules, use the new macro DEFUE.

20782 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20783 since callers should never pass a negative size.
20784 Change the signature to match that of plain 'read' and 'write'; see
20785 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20786 * lisp.h: Update prototypes of emacs_write and emacs_read.
20788 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20790 * xdisp.c (redisplay_window): Don't try to determine the character
20791 position of the scroll margin if the window start point w->startp
20792 is outside the buffer's accessible region. (Bug#8468)
20794 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20796 Fix write-region and its subroutines for buffers > 2GB.
20797 * fileio.c (a_write, e_write): Modify declaration of arguments and
20798 local variables to support buffers larger than 2GB.
20799 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20801 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20802 argument, local variables, and return value.
20804 * lisp.h: Update prototypes of emacs_write and emacs_read.
20806 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20808 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20810 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

20814 * xdisp.c (vmessage): Use a better test for character truncation.
20816 * charset.c (load_charset_map): <, not <=, for optimization,

20826 * callint.c (Fcall_interactively): <, not <=, for optimization.
20827 (Fcall_interactively): Count the number of arguments produced,
20828 not the number of arguments given. This is simpler and lets GCC
20829 4.6.0 generate slightly better code.
20831 * ftfont.c: Distingish more carefully between FcChar8 and char.
20832 The previous code passed unsigned char * to a functions like
20833 strlen and xstrcasecmp that expect char *, which does not
20834 conform to the C standard.
20835 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20836 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20837 char * when the C standard requires it.
20839 * keyboard.c (read_char): Remove unused var.
20841 * eval.c: Port to Windows vsnprintf (Bug#8435).

20844 (verror): Do not give up if vsnprintf returns a negative count.
20845 Instead, grow the buffer. This ports to Windows vsnprintf, which
20846 does not conform to C99. Problem reported by Eli Zaretskii.
20847 Also, simplify the allocation scheme, by avoiding the need for
20848 calling realloc, and removing the ALLOCATED variable.
20850 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20852 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20853 But keep the doprint source code for now, as we might revamp it
20854 and use it again (Bug#8435).
20855 * lisp.h (doprnt): Remove.
20856 * Makefile.in (base_obj): Remove doprnt.o.
20857 * deps.mk (doprnt.o): Remove.
20859 error: Print 32- and 64-bit integers portably (Bug#8435).
20860 Without this change, on typical 64-bit hosts error ("...%d...", N)
20861 was used to print both 32- and 64-bit integers N, which relied on
20862 undefined behavior.
20863 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20864 * lisp.h (error, verror): Mark as printf-like functions.
20865 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20866 Report overflow in size calculations when allocating printf buffer.
20867 Do not truncate output string at its first null byte.
20868 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20869 Truncate the output at a character boundary, since vsnprintf does not
20871 * charset.c (check_iso_charset_parameter): Convert internal
20872 character to string before calling 'error', since %c now has the
20874 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20875 overflow when computing char to be passed to 'error'. Do not
20876 pass Lisp_Object to 'error'; pass the integer instead.
20877 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20878 formatted with plain %d.
20880 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20882 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20884 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20886 * xterm.c (x_catch_errors): Remove duplicate declaration.
20888 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20890 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20892 2011-04-10 Jim Meyering <meyering@redhat.com>
20894 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20895 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20896 return ssize_t not "int", and use size_t as the buffer length.
20897 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20898 * gnutls.h: Update declarations.
20899 * process.c (read_process_output): Use ssize_t, to match.
20900 (send_process): Likewise.
20902 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20904 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20906 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20908 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20909 Use unsigned char, to match FcChar8 type definition.
20911 * xterm.c (handle_one_xevent):
20912 * xmenu.c (create_and_show_popup_menu):
20913 * xselect.c (x_decline_selection_request)
20914 (x_reply_selection_request): Avoid type-punned deref of X events.
20916 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20918 Fix some uses of `int' instead of EMACS_INT.

20925 * xdisp.c (display_count_lines): 3rd argument and return value now
20926 EMACS_INT. All callers changed.
20927 (pint2hrstr): Last argument is now EMACS_INT.
20929 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)

20942 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20943 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20945 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20946 (encode_invocation_designation): Last argument P_NCHARS is now
20948 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20949 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20951 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20954 * ccl.c (Fccl_execute_on_string): Declare some variables
20957 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

20972 instead of using internal_with_output_to_temp_buffer.
20973 (Qhelp_form_show): New var.
20974 (syms_of_keyboard): Use DEFSYM macro.
20976 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20989 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20991 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>

21010 to system-supplied API.
21012 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21014 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21015 This avoids several warnings with gcc -Wstrict-overflow.
21016 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21017 directly, rather than having caller test rule sign. This avoids
21018 some unnecessary tests.
21019 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21020 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21021 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21023 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21024 (xfont_open): Avoid unnecessary tests.
21026 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21028 * composite.h, composite.c (composition_gstring_put_cache):
21029 Use EMACS_INT, not int, for length.

21032 breaking out part of COMPOSITION_DECODE_RULE.
21033 (COMPOSITION_DECODE_RULE): Use it.
21034 * composite.c (get_composition_id): Remove unused local vars,
21035 by using the new macro.
21037 * textprop.c (set_text_properties_1): Change while to do-while,
21038 since the condition is always true at first.
21040 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21041 (interval_deletion_adjustment): Return unsigned value.
21044 * process.c (list_processes_1, create_pty, read_process_output):
21045 (exec_sentinel): Remove vars that were set but not used.
21046 (create_pty): Remove unnecessary "volatile"s.

21058 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21060 * print.c (print_error_message): Avoid int overflow.
21062 * font.c (font_list_entities): Redo for clarity,
21063 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21065 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21066 (font_score): Avoid potential overflow in diff calculation.
21068 * fns.c (substring_both): Remove var that is set but not used.
21069 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21071 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21073 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21074 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21075 can always succeed if overflow has undefined behavior.
21077 * search.c (boyer_moore, wordify): Remove vars set but not used.
21078 (wordify): Omit three unnecessary tests.
21080 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21081 All callers changed. This avoids the need for an unused var.
21083 * casefiddle.c (casify_region): Remove var that is set but not used.
21085 * dired.c (file_name_completion): Remove var that is set but not used.
21087 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21089 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21090 (Finsert_file_contents): Remove unnecessary code checking fd.
21092 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21093 Check for integer overflow on size calculations.
21095 * buffer.c (Fprevious_overlay_change): Remove var that is set
21098 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21099 Remove vars that are set but not used.
21100 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21101 (timer_check_2): Mark vars as initialized.
21103 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21105 * image.c (lookup_image): Remove var that is set but not used.
21106 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21108 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21109 that are set but not used.
21111 * xfns.c (make_invisible_cursor): Don't return garbage
21112 if XCreateBitmapFromData fails (Bug#8410).
21114 * xselect.c (x_get_local_selection, x_handle_property_notify):
21115 Remove vars that are set but not used.
21117 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21118 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21120 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21121 Remove var that is set but not used.
21122 (scroll_bar_windows_size): Now size_t, not int.
21123 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21124 Check for overflow.
21126 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21127 (map_tty_color) [!defined MSDOS]: Likewise.
21129 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21131 * coding.c: Remove vars that are set but not used.
21132 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21133 All callers changed.
21134 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21135 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21136 (decode_coding_charset): Remove vars that are set but not used.
21138 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21139 that is set but not used.
21141 * print.c (print_object): Remove var that is set but not used.
21143 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21144 The gnulib version avoids calling malloc in the usual case,
21145 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21146 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21147 * filelock.c (current_lock_owner): Likewise.
21148 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21149 * sysdep.c: Include allocator.h, careadlinkat.h.
21150 (emacs_no_realloc_allocator): New static constant.
21151 (emacs_readlink): New function.
21152 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21153 ../lib/careadlinkat.h.
21155 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21157 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21158 first non-nil return value).
21160 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21162 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21163 if not defined (Bug#8403).

21172 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21173 and thereabouts. All callers changed.
21174 (get_per_char_metric): Remove parameter `f', unused since
21175 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21177 2011-04-02 Jim Meyering <meyering@redhat.com>
21179 do not dereference NULL upon failed strdup
21180 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21181 (ns_get_family): Likewise.
21183 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21185 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21187 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21189 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

21207 (syms_of_lread): Declare `lexical-binding'.
21209 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21211 * keyboard.c (eval_dyn): New fun.
21212 (menu_item_eval_property): Use it.
21214 * image.c (parse_image_spec): Use Ffunctionp.
21216 * fns.c (concat, mapcar1): Accept byte-code-functions.
21218 * eval.c (Fsetq): Handle lexical vars.
21219 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21220 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21221 (FletX, Flet): Obey lexical binding.
21222 (Fcommandp): Handle closures.
21223 (Feval): New `lexical' arg.
21224 (eval_sub): New function extracted from Feval. Use it almost
21225 everywhere where Feval was used. Look up vars in lexical env.
21227 (Ffunctionp): Move from subr.el.
21228 (Ffuncall): Handle closures.
21229 (apply_lambda): Remove `eval_flags'.
21230 (funcall_lambda): Handle closures and new byte-code-functions.
21231 (Fspecial_variable_p): New function.
21232 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21233 but without exporting it to Lisp.
21235 * doc.c (Fdocumentation, store_function_docstring):
21236 * data.c (Finteractive_form): Handle closures.
21238 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21241 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21243 (exec_byte_code): New function extracted from Fbyte_code to handle new
21244 calling convention for byte-code-functions. Add new byte-codes.
21246 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21248 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21250 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21252 * xdisp.c (redisplay_internal): Fix prototype.
21254 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21256 * xdisp.c (SCROLL_LIMIT): New macro.
21257 (try_scrolling): Use it when setting scroll_limit.
21258 Limit scrolling to 100 screen lines.
21259 (redisplay_window): Even when falling back on "recentering",
21260 position point in the window according to scroll-conservatively,
21261 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21263 (try_scrolling): When point is above the window, allow searching
21264 as far as scroll_max, or one screenful, to compute vertical
21265 distance from PT to the scroll margin position. This prevents
21266 try_scrolling from unnecessarily failing when
21267 scroll-conservatively is set to a value slightly larger than the
21268 window height. Clean up the case of PT below the margin at bottom
21269 of window: scroll_max can no longer be INT_MAX. When aggressive
21270 scrolling is in use, don't let point enter the opposite scroll
21271 margin as result of the scroll.
21272 (syms_of_xdisp) <scroll-conservatively>: Document the
21273 threshold of 100 lines for never-recentering scrolling.

21280 (message_log_check_duplicate): Remove parameters `prev_bol' and
21281 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21282 (redisplay_internal): Remove parameter `preserve_echo_area',
21283 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21285 * indent.c (Fvertical_motion):
21286 * window.c (window_scroll_pixel_based, Frecenter):
21287 Don't pass `need_y_p' to `move_it_by_lines'.
21289 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21291 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21292 steal a few bits to be more compact.
21293 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21294 Remove unneeded casts.
21296 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21298 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21300 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21301 binding" message (bug#7967).
21303 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21305 Fix more problems found by GCC 4.6.0's static checks.
21307 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21308 Remove unused local var.
21310 * editfns.c (Fmessage_box): Remove unused local var.
21312 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21313 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21314 Omit unused local vars.
21315 * window.c (shrink_windows): Omit unused local var.
21316 * menu.c (digest_single_submenu): Omit unused local var.
21317 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21318 Omit unused local var.
21320 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21321 Don't assume string length fits in int.
21322 (keyremap_step, read_key_sequence): Use size_t for sizes.
21323 (read_key_sequence): Don't check last_real_key_start redundantly.
21325 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21326 instead of alloca (Bug#8344).
21328 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21329 (Fbacktrace_frame): Don't assume nframes fits in int.
21331 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21333 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21336 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21338 * cm.c (calccost): Turn while-do into do-while, for clarity.
21340 * keyboard.c (syms_of_keyboard): Use the same style as later
21341 in this function when indexing through an array. This also
21342 works around GCC bug 48267.
21344 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21346 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

21349 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21351 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21352 This avoids undefined behavior on integer overflow, and is a bit
21353 more convenient anyway since it is compared to a size_t variable.
21355 Variadic C functions now count arguments with size_t, not int.
21356 This avoids an unnecessary limitation on 64-bit machines, which
21357 caused (substring ...) to crash on large vectors (Bug#8344).
21358 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21359 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21360 All variadic functions and their callers changed accordingly.
21361 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21365 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21366 (funcall_lambda, mark_backtrace): Likewise.
21367 * fns.c (concat): Likewise.
21368 * frame.c (x_set_frame_parameters): Likewise.
21369 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21370 0 if not found, not -1. All callers changed.
21372 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21373 (stack_copy_size): Now size_t, not int.
21374 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21376 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21378 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21379 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21380 All callers changed.
21382 * lisp.h (multibyte_char_to_unibyte):
21383 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21384 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21386 * cmds.c (internal_self_insert):
21387 * editfns.c (general_insert_function):
21388 * keymap.c (push_key_description):
21389 * search.c (Freplace_match):
21390 * xdisp.c (message_dolog, set_message_1): All callers changed.
21392 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21394 * keyboard.c (safe_run_hook_funcall): New function.
21395 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21396 don't set the hook to nil, but remove the offending function instead.
21397 (Qcommand_hook_internal): Remove, unused.
21398 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21399 Vcommand_hook_internal.
21401 * eval.c (enum run_hooks_condition): Remove.
21402 (funcall_nil, funcall_not): New functions.
21403 (run_hook_with_args): Call each function through a `funcall' argument.
21404 Remove `cond' argument, now redundant.
21405 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21406 (Frun_hook_with_args_until_failure): Adjust accordingly.
21407 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21409 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21411 * dispextern.h (string_buffer_position): Remove declaration.
21413 * print.c (strout): Remove parameter `multibyte', unused since
21414 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21416 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21417 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21418 All callers changed.
21420 * w32.c (_wsa_errlist): Use braces for struct initializers.
21422 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21423 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21424 All callers changed.
21425 (string_buffer_position): Likewise. Also, make static (it's never
21426 used outside xdisp.c).
21427 (cursor_row_p): Remove parameter `w', unused since
21428 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21430 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21431 All callers changed.
21433 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21435 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21440 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
21441 (ns_update_auto_hide_menu_bar): New functions.
21442 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21446 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21448 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21461 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21463 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21464 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21466 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21468 * w32.c (read_unc_volume): Use parameter `henum', instead of
21469 global variable `wget_enum_handle'.
21471 * keymap.c (describe_vector): Remove parameters `indices' and
21472 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21483 * w32menu.c (w32_menu_display_help):
21484 * xmenu.c (show_help_event, menu_help_callback):
21485 Adjust calls to `show_help_echo'.
21487 * gtkutil.c (xg_maybe_add_timer):
21488 * keyboard.c (readable_events):
21489 * process.c (wait_reading_process_output):
21490 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21492 * insdel.c (adjust_markers_gap_motion):
21493 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21567 2011-03-23 Julien Danjou <julien@danjou.info>
21569 * term.c (Fsuspend_tty, Fresume_tty):
21570 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21571 * window.c (temp_output_buffer_show):

21576 * editfns.c (save_excursion_restore):
21577 * cmds.c (internal_self_insert):
21578 * callint.c (Fcall_interactively):
21579 * buffer.c (Fkill_all_local_variables):
21580 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21582 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21583 unconditionally since it does the check itself.
21585 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21587 Fix more problems found by GCC 4.5.2's static checks.
21589 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21590 the first time through the loop, since we know p0 < p1 then.
21591 This also avoids a gcc -Wstrict-overflow warning.
21593 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21594 leading to a memory leak, possible in functions like
21595 load_charset_map_from_file that can allocate an unbounded number
21596 of objects (Bug#8318).
21598 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21599 that could (at least in theory) be that large.
21601 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21602 This is less likely to overflow, and avoids undefined behavior if
21603 overflow does occur. All callers changed. Use strtoul to scan
21604 for the unsigned long integer.
21605 (pint2hrstr): Simplify and tune code slightly.
21606 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21616 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21619 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21621 * process.c (Fmake_network_process): Use socklen_t, not int,
21622 where POSIX says socklen_t is required in portable programs.
21623 This fixes a porting bug on hosts like 64-bit HP-UX, where
21624 socklen_t is wider than int (Bug#8277).
21625 (Fmake_network_process, server_accept_connection):
21626 (wait_reading_process_output, read_process_output):
21629 * process.c: Rename or move locals to avoid shadowing.
21630 (list_processes_1, Fmake_network_process):
21631 (read_process_output_error_handler, exec_sentinel_error_handler):
21632 Rename or move locals.
21633 (Fmake_network_process): Define label "retry_connect" only if needed.
21634 (Fnetwork_interface_info): Fix pointer signedness.

21636 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21637 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21639 Make tparam.h and terminfo.c consistent.
21640 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21641 Include tparam.h instead, since it declares them.
21642 * cm.h (PC): Remove extern decl; tparam.h now does this.
21643 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21644 * terminfo.c: Include tparam.h, to check interfaces.
21645 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21646 (tparam): Adjust signature to match interface in tparam.h;
21647 this removes some undefined behavior. Check that outstring and len
21648 are zero, which they always are with Emacs.
21649 * tparam.h (PC, BC, UP): New extern decls.
21651 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21652 (xftfont_open): Rename locals to avoid shadowing.
21654 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21655 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21656 (OTF_TAG_SYM): Omit macro if not needed.
21657 (ftfont_list): Remove unused local.
21658 (get_adstyle_property, ftfont_pattern_entity):
21659 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21660 Rename locals to avoid shadowing.
21662 * xfont.c (xfont_list_family): Mark var as initialized.
21664 * xml.c (make_dom): Now static.
21666 * composite.c (composition_compute_stop_pos): Rename local to
21668 (composition_reseat_it): Remove unused locals.
21669 (find_automatic_composition, composition_adjust_point): Likewise.
21670 (composition_update_it): Mark var as initialized.
21671 (find_automatic_composition): Mark vars as initialized,
21672 with a FIXME (Bug#8290).
21674 character.h: Rename locals to avoid shadowing.
21675 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21676 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21677 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21678 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21679 to avoid shadowing.
21681 * textprop.c (property_change_between_p): Remove; unused.
21683 * intervals.c (interval_start_pos): Now static.
21685 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21687 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21688 Rename locals to avoid shadowing.
21690 * sound.c (wav_play, au_play, Fplay_sound_internal):
21691 Fix pointer signedness.
21692 (alsa_choose_format): Remove unused local var.
21693 (wav_play): Initialize a variable to 0, to prevent undefined
21694 behavior (Bug#8278).
21696 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21698 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21700 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21701 clobbering (Bug#8298).
21702 * sysdep.c (sys_subshell): Likewise.
21703 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21705 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21706 This should get cleaned up, so that child_setup has the
21707 same signature on all platforms.
21709 * callproc.c (call_process_cleanup): Now static.
21710 (relocate_fd): Rename locals to avoid shadowing.
21712 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21714 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21715 not to be necessary, and produces flickering.
21717 2011-03-20 Glenn Morris <rgm@gnu.org>
21719 * config.in: Remove file.
21721 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21723 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21724 are now in src/globals.h.
21725 (syms_of_minibuf): Remove spurious & from previous change.

21735 * xfaces.c (Fx_load_color_file):
21736 Read color file from absolute filename (bug#8250).

21825 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
21826 (Fdefvar): Rewrite so as not to use empty "else".

21840 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21841 some of which prompt warnings from gcc -Wbad-function-cast.
21842 (Fformat_time_string, Fencode_time, Finsert_char):
21843 (Ftranslate_region_internal, Fformat):

21874 avoids undefined behavior in theory.
21876 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21878 Use functions, not macros, for up- and down-casing (Bug#8254).
21879 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21880 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21881 to use the following functions instead of these macros.
21882 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21883 EMACS_INT, since callers assume the returned value fits in int.
21884 (upcase1): Likewise, for UPCASE_TABLE.
21885 (uppercasep, lowercasep, upcase): New static inline functions.
21886 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21892 (regex_compile, re_search_2, re_match_2_internal):
21893 Remove unused local vars.

21895 which gcc can warn about.
21896 (regex_compile, re_match_2_internal): Mark locals as initialized.
21897 (RETALLOC_IF): Define only if needed.
21898 (WORDCHAR_P): Likewise. This one is never needed, but is used
21899 only in a comment talking about a compiler bug, so put inside
21900 the #if 0 of that comment.
21901 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21902 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21905 * search.c (boyer_moore): Rename locals to avoid shadowing.

21920 Rename locals to avoid shadowing.
21921 (Fvertical_motion): Mark locals as initialized.
21923 * casefiddle.c (casify_object, casify_region): Now static.
21924 (casify_region): Mark local as initialized.

21928 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21929 New macros, so that the caller can use some names other than
21930 gcpro1, gcpro2, etc.
21931 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21933 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21934 argument, for consistency with GCPRO2_VAR, etc: it is now the
21935 prefix of the variable, not the variable itself. All uses
21937 * dired.c (directory_files_internal, file_name_completion):
21938 Rename locals to avoid shadowing.
21940 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21941 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21942 dired.c's scmp function, had undefined behavior.
21943 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21944 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21945 * buffer.h: ... to here, because these macros use current_buffer,
21946 and the new implementation with inline functions needs to have
21947 current_buffer in scope now, rather than later when the macros
21949 (downcase, upcase1): New static inline functions.
21950 (DOWNCASE, UPCASE1): Reimplement using these functions.
21951 This avoids undefined behavior in expressions like
21952 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21953 from race conditions in accessing the global variables
21954 case_temp1 and case_temp2.
21955 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21956 * lisp.h (case_temp1, case_temp2): Remove their decls.
21957 * character.h (ASCII_CHAR_P): Move from here ...
21958 * lisp.h: ... to here, so that the inline functions mentioned
21959 above can use them.
21961 * dired.c (directory_files_internal_unwind): Now static.
21963 * fileio.c (file_name_as_directory, directory_file_name):
21964 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21966 (file_name_as_directory): Use const pointers when appropriate.
21967 (Fexpand_file_name): Likewise. In particular, newdir might
21968 point at constant storage, so make it a const pointer.
21969 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21970 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21972 (Fset_file_times, Finsert_file_contents, auto_save_error):
21973 Rename locals to avoid shadowing.

21977 to avoid shadowing.
21979 * marker.c (bytepos_to_charpos): Remove; unused.
21981 * lisp.h (verify_bytepos, count_markers): New decls,
21982 so that gcc does not warn that these functions aren't declared.
21984 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21985 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21986 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21987 (copy_text): Remove unused local var.
21989 * filelock.c (within_one_second): Now static.
21990 (lock_file_1): Rename local to avoid shadowing.
21992 * buffer.c (fix_overlays_before): Mark locals as initialized.
21993 (fix_start_end_in_overlays): Likewise. This function should be
21994 simplified by using pointers-to-pointers, but that's a different
21996 (switch_to_buffer_1): Now static.
21997 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21998 (report_overlay_modification): Rename locals to avoid shadowing.
22000 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22001 Fix pointer signedness issue.
22002 (sys_subshell): Mark local as volatile if checking for lint,
22003 to suppress a gcc -Wclobbered warning that does not seem to be right.
22004 (MAXPATHLEN): Define only if needed.
22006 * process.c (serial_open, serial_configure): Move decls from here ...
22007 * systty.h: ... to here, so that they can be checked.
22009 * fns.c (get_random, seed_random): Move extern decls from here ...
22010 * lisp.h: ... to here, so that they can be checked.
22012 * sysdep.c (reset_io): Now static.
22013 (wait_for_termination_signal): Remove; unused.
22015 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22016 (copy_keymap_item, append_key, push_text_char_description):
22018 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22019 (DENSE_TABLE_SIZE): Remove; unused.
22020 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22021 (describe_map_tree):
22022 Rename locals to avoid shadowing.
22024 * keyboard.c: Declare functions static if they are not used elsewhere.
22025 (echo_char, echo_dash, cmd_error, top_level_2):
22026 (poll_for_input, handle_async_input): Now static.
22027 (read_char, kbd_buffer_get_event, make_lispy_position):
22028 (make_lispy_event, make_lispy_movement, apply_modifiers):
22029 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
22030 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
22031 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
22032 (read_key_sequence, read_char): Mark locals as initialized.

22109 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22110 These macros can no longer be used for assignment.
22112 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

22168 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
22170 Improve quality of tests for time stamp overflow.
22171 For example, without this patch (encode-time 0 0 0 1 1
22172 1152921504606846976) returns the obviously-bogus value (-948597
22173 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22174 reports time overflow. See
22175 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
22176 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
