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

11 (temacs$(EXEEXT)): Use $(ALLOBJS).
12 * autodeps.mk (ALLOBJS): Move to Makefile.in.
13 * deps.mk (vm-limit.o):
14 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
15 Do not depend on mem-limits.h.
16 * emacs.c (__do_global_ctors, __do_global_ctors_aux)

22 (make_hdr): Use DATA_START instead of start_of_data.
23 * vm-limit.c: Move most of mem-limits.h's contents here.
24 (data_start): New decl. It's OK if this is approximate,
25 so simplify-away some unnecessary exactness.
26 (POINTER): Remove; all uses removed.
27 (data_space_start): Now char *, to avoid casts.
28 (exceeds_lisp_ptr): New function, replacing the old
29 EXCEEDS_LISP_PTR macro. All uses changed.

45 and diagnosed by Andreas Schwab in
46 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
48 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
51 * ralloc.c (SIZE, POINTER, NIL):
52 * vm-limit.c (POINTER):
53 Remove, replacing all uses with C89 equivalents. These old
54 symbols were present only for porting to pre-C89 platforms.
56 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
58 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
59 This avoids warning messages reported as part of Bug#13546.
61 2013-02-21 Ken Brown <kbrown@cornell.edu>
63 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

72 (syms_of_keyboard): Adjust accordingly.
74 2013-02-19 Daniel Colascione <dancol@dancol.org>
76 * sheap.c (report_sheap_usage): Use message, not message1, so
77 that we don't try to create a buffer while we're in the middle
78 of dumping Emacs. Explain why.
80 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
81 * search.c (find_newline): Return byte position in bytepos.

101 * xdisp.c (x_draw_vertical_border): For a window that is neither
102 the leftmost nor the rightmost, redraw both the left and the right
103 vertical borders. (Bug#13723)
105 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
107 * xml.c (init_libxml2_functions):

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

176 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
178 Fix AIX port (Bug#13650).
179 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
180 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
181 was #undeffed earlier, so it cannot be used as a macro here.
182 Use the constant and not the macro.
184 2013-02-15 Eli Zaretskii <eliz@gnu.org>
186 * w32proc.c (new_child): If no vacant slots are found in
187 child_procs[], make another pass looking for slots whose process

194 STATUS_READ_IN_PROGRESS. (Bug#13546)
196 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
198 * gtkutil.c (tb_size_cb): New function.

203 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
206 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
208 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
210 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

218 2013-02-13 Glenn Morris <rgm@gnu.org>
220 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
222 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
224 Improve AIX port some more (Bug#13650).
225 With this, it should be as good as it was in 23.3, though it's
226 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
227 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
228 * unexaix.c (start_of_text): Remove.
229 (_data, _text): Declare as char[], not int, as AIX manual suggests.
230 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
231 (orig_load_scnptr, orig_data_scnptr):
232 Now off_t, not long, since they are file offsets.
233 (make_hdr): Use _data, not start_of_data ().
234 This is the key part of the fix.
235 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
236 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
238 * pre-crt0.c (data_start): Initialize to 1.
239 This ports to compilers that optimize the external declaration
240 'int x = 0;' as if it were 'int x;' to shrink the executable.
242 Improve AIX port (Bug#13650).
243 This doesn't fix the bug, but it makes progress: Emacs builds now.
244 * unexaix.c: Include inttypes.h, stdarg.h.
245 (report_error, report_error_1): Mark as _Noreturn.
246 (report_error): Don't report the wrong errno.
247 (report_error_1): Now varargs. All callers changed.
248 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
249 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
250 (write_ptr): Use %p to print address rather than %lx and a cast
251 to unsigned long. Grow buffer a bit, to be safer.
253 2013-02-13 Eli Zaretskii <eliz@gnu.org>
255 * bidi.c (bidi_resolve_neutral): After finding the next
256 non-neutral character, accept NEUTRAL_ON type as well, because
257 directional control characters, such as LRE and RLE, have their
258 type converted to that by bidi_resolve_weak. This avoids aborts
259 when LRE/RLE follows a run of neutrals.
260 (bidi_move_to_visually_next): Assert that return value of
261 bidi_peek_at_next_level is non-negative. Negative values will
264 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
266 Minor getenv-related fixes.
267 * callproc.c (Fcall_process_region) [!DOS_NT]:
268 Avoid unnecessary duplicate call to getenv.
269 * callproc.c (init_callproc):
270 * dispnew.c (init_display):

272 Omit unnecessary cast of getenv or egetenv.
274 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
276 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
279 2013-02-12 Eli Zaretskii <eliz@gnu.org>
281 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
283 (display_line): Set w->region_showing to the value of
284 it->region_beg_charpos, not to -1. This fixes redisplay
285 optimization when cursor is moved up after M->. (Bug#13623)
287 (try_scrolling): Scroll text up more if point is too close to ZV
288 and inside the scroll margin. This makes sure point is moved
289 outside the scroll margin in these cases.
291 * window.h (struct window): region_showing can no longer be
294 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
296 Tune by using memchr and memrchr.
297 * doc.c (Fsnarf_documentation):
298 * fileio.c (Fsubstitute_in_file_name):
299 * search.c (find_newline, scan_newline):
300 * xdisp.c (pos_visible_p, display_count_lines):
301 Use memchr and memrchr rather than scanning byte-by-byte.
302 * search.c (find_newline): Rename from scan_buffer.
303 Omit first arg TARGET, as it's always '\n'. All callers changed.
305 Clean up read_key_sequence a tiny bit more.
306 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
307 (read_key_sequence): Remove unused locals.
309 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
311 Clean up read_key_sequence a bit; reread active keymaps after first event.
312 * keyboard.c (read_char, read_char_x_menu_prompt)
313 (read_char_minibuf_menu_prompt):
314 Replace nmaps+maps with a single `map' arg.
315 (follow_key): Operate on a single map.
316 (active_maps): New function.
317 (test_undefined): Also return true for nil bindings.
318 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
319 a single (composed) keymap. Remember `first_event' to choose the right
320 set of active keymaps. Recompute the set of keymaps after receiving
321 the first event. Remove GOBBLE_FIRST_EVENT.
322 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
323 * keyboard.h (read_char): Update declaration.
324 * lread.c (read_filtered_event): Adjust call to read_char.
326 2013-02-11 Eli Zaretskii <eliz@gnu.org>
328 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
329 Don't use the limitation on backwards movement when lines are truncated
330 in the window. (Bug#13675)
332 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
334 * marker.c (set_marker_internal): If desired position is passed
335 as a marker, avoid call to buf_charpos_to_bytepos.
336 * window.c (Fset_window_point): Omit redundant type checking.
337 (Fset_window_start): Likewise. Format comment.
338 (window_scroll_pixel_based): Use set_marker_restricted_both
339 with character and byte positions obtained from an iterator.
340 (Fset_window_configuration): Use set_marker_restricted_both.
341 * xdisp.c (message_dolog): Likewise.
343 2013-02-10 Eli Zaretskii <eliz@gnu.org>
345 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
346 When text lines are longer than window's screen lines, don't move back
347 too far. This speeds up some redisplay operations. (Bug#13675)
349 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
351 * syntax.c (scan_sexps_forward): Fix byte position calculation
352 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
354 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
356 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
359 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
361 Minor hashing refactoring.
362 * fns.c (SXHASH_REDUCE): Move to lisp.h.
363 (sxhash_float): Return EMACS_UINT, for consistency with the other
365 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
366 non-static inline function and therefore can't use static vars.
367 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
368 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
369 with the other hash functions.
371 2013-02-09 Eli Zaretskii <eliz@gnu.org>
373 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
374 XXXXXX part of the temporary file pattern is not downcased even
375 when w32-downcase-file-names is non-nil. (Bug#13661)
377 * xdisp.c (decode_mode_spec): Remove handling of %t.
379 * msdos.c (careadlinkatcwd): Remove.
381 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>

463 2013-02-04 Eli Zaretskii <eliz@gnu.org>
465 * xdisp.c (window_buffer_changed): region_showing can be negative,

478 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
479 daemon mode works on cygw32 when Emacs is installed and not just
482 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
484 Avoid file time stamp bug on MS-Windows (Bug#13149).
485 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
486 as FAT32 doesn't update time stamps when truncating them.
487 Also, check that a file time stamp is not a multiple of 100 ns;
488 this should catch all instances of the problem on MS-Windows,
489 as its native file system resolution is 100 ns or worse, and
490 checking for a non-multiple of 100 ns should impose only a small
491 overhead on systems with ns resolution.
493 2013-02-02 Eli Zaretskii <eliz@gnu.org>
495 Avoid encoding file names on MS-Windows when they need to be run
496 through dostounix_filename.
497 * w32.c (normalize_filename): Accept an additional argument
498 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
499 downcase it even if w32-downcase-file-names is non-nil.
500 (dostounix_filename): Accept an additional argument MULTIBYTE and
501 pass it to normalize_filename.
502 (emacs_root_dir): Adjust.
504 * msdos.h (dostounix_filename): Adjust prototype.
506 * w32.h (dostounix_filename): Adjust prototype.
508 * msdos.c (dostounix_filename): Accept an additional argument and
510 (init_environment): Adjust callers of dostounix_filename.
512 * fileio.c (Ffile_name_directory, file_name_as_directory)
513 (directory_file_name, Fexpand_file_name)
514 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
516 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
518 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
519 variables, as egetenv is case-insensitive for DOS_NT.
521 * dired.c (file_name_completion): Don't call Fdirectory_file_name
522 with an encoded file name.
524 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
525 Adjust calls to dostounix_filename.
527 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
529 * unexw32.c (unexec): Adjust call to dostounix_filename.
531 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
533 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
536 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
539 * callproc.c (Fcall_process): Make sure program name in PATH and
540 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
541 is passed to exec/spawnve, which fails unless the file-name
544 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
545 even if w32-quote-process-args is nil.
547 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
549 Fix timestamp bug when write-region appends nothing (Bug#13149).
550 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
551 the file's time stamp doesn't change if Emacs happens to write nothing
552 to the file, and on a buggy file system this could cause Emacs to
553 incorrectly infer that the file system doesn't have the bug.
554 Avoid this problem by inhibiting the inference in this case.
556 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
558 * window.h (struct window): Convert base_line_number, base_line_pos
559 and column_number_displayed members from Lisp_Object to ptrdiff_t.
560 Convert region_showing member from Lisp_Object to bitfield.
561 Remove sequence_number member. Adjust comments.
562 * window.c (sequence_number): Remove.
563 (make_window): Initialize column_number_displayed.
564 * print.c (print_object): Follow the printed representation of
565 frames and print window pointer to distinguish between windows.
566 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
567 * xdisp.c (wset_base_line_number, wset_base_line_pos)
568 (wset_column_number_displayed, wset_region_showing): Remove.
569 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
570 (try_scrolling, try_cursor_movement, redisplay_window)
571 (try_window_reusing_current_matrix, try_window_id, display_line)
572 (display_mode_lines, decode_mode_spec): Adjust users.
573 * .gdbinit (pwinx): Do not print sequence_number.
575 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
577 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
578 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
579 * dired.c: Include <fcntl.h>.
580 (open_directory): New function, which uses open and fdopendir
581 rather than opendir. DOS_NT platforms still use opendir, though.
582 (directory_files_internal, file_name_completion): Use it.
583 (file_attributes): New function, with most of the old Ffile_attributes.
584 (directory_files_internal, Ffile_attributes): Use it.
585 (file_attributes, file_name_completion_stat): First arg is now fd,
586 not dir name. All uses changed. Use fstatat rather than lstat +
588 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
589 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
590 (emacs_readlinkat): New function, with much of the old
591 Ffile_symlink_p, but with an fd argument for speed.
592 It uses readlinkat rather than careadlinkatcwd, so that it
593 need not assume the working directory.
594 (Ffile_symlink_p): Use it.
595 * filelock.c (current_lock_owner): Use emacs_readlinkat
596 rather than emacs_readlink.
597 * lisp.h (emacs_readlinkat): New decl.
598 (READLINK_BUFSIZE, emacs_readlink): Remove.
599 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
600 (emacs_norealloc_allocator, emacs_readlink): Remove.
601 This stuff is moved to fileio.c.
602 * w32.c (fstatat, readlinkat): New functions.
603 (careadlinkat): Don't check that fd == AT_FDCWD.
604 (careadlinkatcwd): Remove; no longer needed.
606 2013-01-31 Glenn Morris <rgm@gnu.org>
608 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
609 (Fwrite_region): Update for new choose_write_coding_system args.
610 Move the last piece of choose_write_coding_system here. (Bug#13522)
611 (syms_of_fileio): Add choose-write-coding-system.
613 2013-01-30 Eli Zaretskii <eliz@gnu.org>
615 * w32.c (sys_open): Zero out the flags for the new file descriptor.
616 (sys_close): Zero out the flags for the file descriptor before
617 closing it. (Bug#13546)
619 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
620 (logon_network_drive, stat_worker, symlink, chase_symlinks):
621 Use CharNextExA and CharPrevExA to iterate over file names encoded in
624 * w32.c (w32_get_long_filename, init_environment, readlink):
625 Support file names encoded in DBCS codepages.
626 (readlink): Use the current file-name-coding-system, not the ANSI
627 codepage, to decode and handle targets of symlinks.
629 2013-01-28 Eli Zaretskii <eliz@gnu.org>
631 * w32.c (opendir): Now accepts a 'const char *'.
633 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
635 Remove obsolete redisplay code. See the discussion at
636 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
637 * dispnew.c (preemption_period, preemption_next_check): Remove.
638 (Vredisplay_preemption_period): Likewise.
639 (update_frame, update_single_window, update_window, update_frame_1):
640 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
641 used, following the 2012-06-22 change.
643 2013-01-25 Eli Zaretskii <eliz@gnu.org>
645 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
647 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
649 * font.c (num_fonts): Remove the leftover from old
650 debugging code. Adjust comment style here and there.
651 * insdel.c (insert_1): Remove.
652 * lisp.h (insert_1): Remove prototype.
653 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
655 2013-01-25 Eli Zaretskii <eliz@gnu.org>
657 * w32.c (max_filename_mbslen): New function.
658 (normalize_filename, readdir): Use it to detect locales where ANSI
659 encoding of file names uses a double-byte character set (DBCS).
660 If a DBCS encoding is used, advance by characters using
661 CharNextExA, instead of incrementing a 'char *' pointer.
662 Use _mbslwr instead of _strlwr. (Bug#13515)
664 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
665 request of memory reservation to 1.7GB. (Bug#13065)
667 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
669 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
670 at check_extra_latin label. (Bug#13505)
672 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
674 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
675 Avoid redundant calls to strlen.
677 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
679 Drop async_visible and async_iconified fields of struct frame.
680 This is possible because async input is gone; for details, see
681 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
682 * frame.h (struct frame): Remove async_visible and async_iconified
683 members, convert garbaged to unsigned bitfield. Adjust comments.
684 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
685 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
686 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
687 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
688 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
690 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
691 properly. Likewise for obscured.
693 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
696 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
698 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
700 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
701 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
703 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
705 * xdisp.c (message2, message2_nolog): Remove functions.
706 (message3, message3_nolog): Extract nbytes and multibyteness directly
707 from the string. Change all callers.
708 (message3_nolog): Don't set message_enable_multibyte since set_message
709 will reset it anyway.
710 (message1, message1_nolog): Use message3.
711 (vmessage): Use a stack allocated buffer rather than f->message_buf.
712 (with_echo_area_buffer): Remove last two arguments. Update all callers.
713 (set_message): Drop all but the second arg, which has to be a string.
714 (set_message_1): Simplify now that we know that a1 is NULL and the
715 second arg is a string.
716 * frame.h (struct frame): Remove `message_buf' field.
717 Use glyphs_initialized_p instead.
718 (FRAME_MESSAGE_BUF): Remove macro.
719 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
720 * lisp.h (message2, message2_nolog): Remove declarations.
721 (message3, message3_nolog): Update declarations.
722 * keyboard.c (read_char_minibuf_menu_text)
723 (read_char_minibuf_menu_width): Remove vars.
724 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
725 to correctly handle multibyte strings.
726 * frame.c (delete_frame): Don't free message_buf any more.
727 * editfns.c (message_text, message_length): Remove vars.
728 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
729 * fileio.c (auto_save_error): Use message3 instead of message2.
730 * dispnew.c (adjust_frame_message_buffer): Remove function.
732 2013-01-23 Eli Zaretskii <eliz@gnu.org>
734 * w32term.c (w32fullscreen_hook): Account correctly for the screen
735 real estate used for the tool bar and the menu bar.
737 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
739 * insdel.c (prepare_to_modify_buffer): Force redisplay if
740 hidden buffer is prepared to modification (Bug#13164).
742 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
744 * window.h (struct window): Change window_end_valid member from
745 Lisp_Object to a bitfield. Adjust comments.
746 (wset_window_end_valid): Remove.
747 * window.c (adjust_window_count): Clear window_end_valid.
748 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
749 (Fwindow_line_height, set_window_buffer, Frecenter)
750 (Fsplit_window_internal, Fdelete_other_windows_internal)
751 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
752 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
753 * xdisp.c (check_window_end, reconsider_clip_changes)
754 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
755 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
756 (find_first_unchanged_at_end_row, try_window_id): Likewise.
758 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
760 * xdisp.c (mark_window_display_accurate): Simplify the loop
761 assuming that the only one of vchild, hchild or buffer window
762 slots is non-nil. Call mark_window_display_accurate_1 for
763 the leaf windows only.
764 (mark_window_display_accurate_1): Always assume leaf window.
767 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
769 * emacs.c (Qkill_emacs_hook): Now static.
771 * fileio.c (Finsert_file_contents): Simplify.
772 Remove unnecessary assignments and tests.
774 2013-01-21 Eli Zaretskii <eliz@gnu.org>
776 * w32.c (acl_set_file): Don't test for errors unless
777 set_file_security returns FALSE. Avoids spurious errors when
780 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
782 * fileio.c (Finsert_file_contents): Revert code introduced at
783 2013-01-18 in favor of the simpler and generally better fix.
784 Save stack space by removing 'buffer' and reusing 'read_buf'
787 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
789 * lisp.h (eabs): Define unconditionally (Bug#13419).
790 The old "#if !defined (eabs)" was an unnecessary revenant of back
791 when this macro was called "abs". Document 'eabs' better.
793 2013-01-19 Glenn Morris <rgm@gnu.org>
795 * fns.c (Frandom): Doc fix.
797 2013-01-19 Eli Zaretskii <eliz@gnu.org>
799 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
800 segfault when there are lots of overlays.
802 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
803 when there are lots of overlays.
804 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
805 for the details and a way to reproduce.
807 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
809 * fileio.c: Use O_APPEND to append.
810 This corresponds better to the natural interpretation of "append",
811 and avoids the need to open the output file twice, or to invoke
812 lseek when APPEND is neither nil nor a number.
813 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
814 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
815 file possibly twice, and lseeking to its end; this avoids the
816 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
817 at the same time: the combination is never needed and apparently
818 it doesn't work with DOS_NT.
820 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
821 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
823 Allow floating-point file offsets.
824 Problem reported by Vitalie Spinu in
825 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
826 * fileio.c (emacs_lseek): Remove.
827 (file_offset): New function.
828 (Finsert_file_contents, Fwrite_region): Use it.
830 2013-01-19 Chong Yidong <cyd@gnu.org>
832 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
833 aborting on Fsignal (Bug#13289).
835 2013-01-19 Eli Zaretskii <eliz@gnu.org>
837 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
838 set_file_security as failure due to insufficient privileges.
839 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
840 (fstat): Return owner and group like 'stat' and 'lstat' do.
842 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
844 Work around bug in CIFS and vboxsf file systems (Bug#13149).
845 The bug was observed on Ubuntu operating inside a virtual machine,
846 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
847 The workaround introduces a race condition on non-buggy hosts,
848 but it's an unlikely race and anyway there's a nearly identical
849 nearby race that can't be fixed.
850 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
852 (Fwrite_region): Test for file system time stamp bug.
853 (init_fileio): New function.
854 * lisp.h (init_fileio): Declare it.
855 * emacs.c (main): Call it.
857 * fileio.c (Finsert_file_contents): Simplify new diagnostic
858 and make it more consistent with other stat-failure diagnostics.
860 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
862 Fix crash when inserting data from non-regular files.
863 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
864 for the error description produced by valgrind.
865 * fileio.c (read_non_regular): Rename to read_contents.
866 Free Lisp_Save_Value object used to pass parameters.
867 (read_non_regular_quit): Rename to read_contents_quit.
868 (Finsert_file_contents): Redesign internal file reading loop to adjust
869 gap and end positions after each read and so help make_gap to work
870 properly. Do not signal an I/O error too early and so do not leave
871 not yet decoded characters in a buffer, which was the reason of
872 redisplay crash. Use list2 to build return value. Adjust comments.
874 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
876 Close a race when statting and reading files (Bug#13149).
877 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
878 This avoids a race if the file is renamed between stat and open.
879 This race is not the problem originally noted in Bug#13149;
880 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
882 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
884 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
885 objects, related functions and macros.
886 (make_save_value): Adjust prototype.
887 (make_save_pointer): New prototype.
888 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
889 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
890 * alloc.c (format_save_value): Rename to make_save_value.
891 (make_save_pointer): New function.
892 (record_xmalloc): Use make_save_pointer.
893 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
894 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
895 Change users of make_save_value to make_save_pointer.
896 Likewise for format_save_value and make_save_value.
898 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
900 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
901 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
902 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
905 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
907 * alloc.c (free_save_value): Now static.
909 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
911 * keymap.c (map_keymap_internal): Use format_save_value.
912 (map_keymap_char_table_item): Adjust accordingly.
913 * fileio.c (non_regular_fd, non_regular_inserted)
914 (non_regular_nbytes): Remove.
915 (Finsert_file_contents): Convert trytry to ptrdiff_t.
916 Use format_save_value to pass parameters to read_non_regular.
917 (read_non_regular): Use XSAVE_ macros to extract parameters.
919 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
921 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
923 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
925 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
926 extraction from any Lisp_Save_Value slot. Add type checking.
927 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
928 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
929 * xselect.c: All users changed.
931 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
933 Some convenient bits to deal with Lisp_Save_Values.
934 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
935 (allocate_misc): Remove prototype.
936 (format_save_value): New prototype.
937 * alloc.c (allocate_misc): Revert back to static.
938 (format_save_value): New function to build Lisp_Save_Value
939 object with the specified internal structure.
940 (make_save_value): Reimplement using format_save_value.
941 * editfns.c (save_excursion_save): Use format_save_value.

979 * editfns.c (save_excursion_save): Pack everything within
980 Lisp_Save_Value and so avoid xmalloc.
981 (save_excursion_restore): Adjust to match new layout. Use free_misc
982 because we do not allocate extra memory any more. Add eassert.
983 * print.c (print_object): New code to print Lisp_Save_Value. Do not
984 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

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

1052 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1054 Avoid unnecessary byte position calculation for the gap movement.
1055 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1066 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1068 * term.c (init_tty): Use them instead of rolling our own code.
1069 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1070 switches from 'signal' to 'pthread_sigmask', which is safer in
1071 multithreaded applications.
1072 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1073 which has already arranged for that.
1074 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1075 This is the main part of the bug fix.

1087 predicate, which is how it's really used now. Adjust comment.
1088 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1089 * buffer.c (buffer_slot_type_mismatch): Remove.
1090 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1091 predicate. Adjust comment.

1094 left-margin-width, right-margin-width, left-fringe-width,
1095 right-fringe-width, scroll-bar-width and buffer-display-count.
1096 Use Qstringp for default-directory, buffer-file-name,
1097 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1098 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1100 * data.c (store_symval_forwarding): Adjust to call the predicate.

1117 (make_gap_1): New function to adjust the gap of any buffer.
1118 * coding.c (coding_alloc_by_making_gap): Use it.
1119 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1143 trailing dash is properly added.
1145 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1147 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1148 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1149 digits for buffer positions, before misalignment starts.
1150 Display "0" for integer "object" field.
1151 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1152 Display the newline glyph more unambiguously.
1154 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1156 * nsterm.m (ns_draw_underwave):
1157 * w32term.c (w32_draw_underwave):
1158 * xterm.c (x_draw_underwave): Make underwave look more triangular
1159 and also degrade gracefully for small fonts. (Bug#13000)
1161 * nsterm.m (ns_draw_text_decoration):
1162 * w32term.c (x_draw_glyph_string):
1163 * xterm.c (x_draw_glyph_string): Don't use previous underline
1164 thickness and position if previous underline type is underwave.
1166 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1168 * fileio.c (Ffile_acl): Undocument return format.
1170 2013-01-02 Glenn Morris <rgm@gnu.org>

1184 * term.c (tty_ins_del_lines):
1185 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1186 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1188 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1190 * w32.c (unsetenv): Set up the string passed to _putenv
1192 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1193 for the bug this caused.
1195 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1197 * coding.c (Qmac): Now static.
1199 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1201 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1202 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1209 by TOOLBAR_TOP_WIDGET.
1210 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1211 Check toolbar_is_packed.
1212 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1213 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1214 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1216 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1217 (xg_update_menubar): Update title only if
1218 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1219 (xg_update_submenu): Skip tearoff only if
1220 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1221 (xg_initialize): Initialize xg_detached_menus only if
1222 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1224 * xterm.h (struct x_output): Surround handlebox_widget with
1225 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1226 toolbar_in_hbox is bool.
1228 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1230 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1231 (LIBS_GNUSTEP): Define.
1232 (LIBES): Add $(LIBS_GNUSTEP).
1233 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1235 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1237 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1238 continuation glyph on a TTY with an indication of an empty line.
1241 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1243 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1244 file's SELinux context or ACLs successfully set, nil otherwise.
1246 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1248 * w32proc.c (reader_thread): Avoid passing NULL handles to
1249 SetEvent and WaitForSingleObject.
1251 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1253 Port EXTERNALLY_VISIBLE to Clang 3.2.
1254 * conf_post.h (__has_attribute): New macro.
1255 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1257 2012-12-27 Glenn Morris <rgm@gnu.org>
1259 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1260 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1262 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1264 * fileio.c (file_name_as_directory, directory_file_name):
1265 Accept an additional argument MULTIBYTE to indicate whether the input C
1266 came from a multibyte or a unibyte Lisp string; all callers
1267 adjusted. Don't assume the input string is always multibyte.
1269 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1270 don't ENCODE_FILE them, and return a unibyte string if the input
1272 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1273 don't assume the input strings will always be multibyte. If the
1274 input strings are multibyte, decode strings obtained from C
1277 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1279 * lisp.h (toplevel): Add two notices to the comment about
1280 defining a new Lisp data type.

1284 * alloc.c (valid_lisp_object_p): Adjust comment.
1286 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1288 * keyboard.c (record_asynch_buffer_change): Initialize an event
1289 only if it's really needed.
1290 * frame.h (enum output_method): Remove output_mac member since
1291 it's a leftover from the deleted code.
1292 * frame.c (Fframep): Adjust user here ...
1293 * terminal.c (Fterminal_live_p): ... and here.
1294 * coding.c (Qmac): Now here because it's only used to denote
1295 end-of-line encoding type.
1296 (syms_of_coding): DEFSYM it.
1297 * frame.h (Qmac): Remove duplicated declaration.
1299 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1301 * window.c (select_window_1): Now static, since it's used only here.
1303 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1305 * window.c (window_body_cols): Subtract display margins from the
1306 window body width on TTYs as well. See
1307 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1308 for the original report.
1310 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1312 * xdisp.c (redisplay_window): Remove inner local variable
1313 because the outer shadowed one has the same meaning.
1314 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1316 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1317 (xg_create_tool_bar): Adjust users.
1319 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1321 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1322 * buffer.c (Fget_buffer_create): Use it to set compact field of
1323 struct buffer_text to avoid accessing an uninitialized value
1324 when compact_buffer is called for the first time.
1325 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1326 (Fset_buffer_modified_p): Use buffer_window_count to check
1327 whether the buffer is displayed in some window.
1328 * xdisp.c (message_dolog): Likewise.
1330 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1332 * w32.c (acl_set_file): If setting the file security descriptor
1333 fails, and the new DACL is identical to the existing one, silently
1334 return success. This fixes problems for users backing up their
1335 own files without having the necessary privileges for setting
1336 security descriptors.
1338 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1340 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1341 after WaitForSingleObject returns normally. This expedites reader
1342 thread shutdown when delete_child triggers it.
1343 (reap_subprocess): More accurate commentary for why we call
1344 delete_child only when cp->fd is negative.
1346 * w32.c (sys_close): Do not call delete_child on a subprocess
1347 whose handle is not yet closed. Instead, set its file descriptor
1348 to a negative value, so that reap_subprocess will call
1349 delete_child on that subprocess when its SIGCHLD arrives.
1350 This avoids closing handles used for communications between sys_select
1351 and reader_thread, which doesn't give sys_select a chance to
1352 notice that the process exited and invoke the SIGCHLD handler for
1355 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1357 * nsfns.m (Fns_do_applescript): Run event loop until script has
1358 been executed (Bug#12969).
1359 (ns_run_ascript): Chech as_script for nil, set to nil after
1362 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1364 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1366 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1368 * w32term.c (w32fullscreen_hook): New function.
1369 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1371 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1373 * fileio.c (Finsert_file_contents): Doc fix.
1375 * w32proc.c (new_child, delete_child, find_child_pid): For a
1376 subprocess, consider its slot being in use as long as its process
1377 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1378 slot when a new process is started immediately after killing
1379 another one, without waiting enough time for the first process to
1380 be reaped and resources allocated for it be orderly freed.
1382 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1384 2012-12-21 Chong Yidong <cyd@gnu.org>
1386 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1388 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1390 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1392 * w32.c (get_name_and_id): Always pass NULL as the first argument
1393 of lookup_account_sid. Avoids crashes with UNC file names that
1394 refer to DFS domains, not to specific machine names. (Bug#12621)
1395 Remove now unused argument FNAME; all callers changed.
1396 (get_file_owner_and_group): Remove now unused argument FNAME; all
1399 2012-12-21 Chong Yidong <cyd@gnu.org>
1401 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1402 error for invalid chars, don't check for a nil return value.
1404 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1406 Avoid calls to CHAR_TO_BYTE if byte position is known.
1407 * editfns.c (make_buffer_string_both): Use move_gap_both.
1408 (Fbuffer_string): Use make_buffer_string_both.
1409 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1411 (buf_bytepos_to_charpos): Likewise.
1412 (charpos_to_bytepos): Remove.
1413 * fileio.c (Finsert_file_contents): Use move_gap_both.
1414 * search.c (Freplace_match): Likewise.
1415 * process.c (process_send_region): Likewise. Use convenient

1490 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1492 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1493 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1494 for some of that bug's symptoms can now cause Emacs to abort.
1495 Remove the workaround.
1496 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1497 The bug that caused SIGCHLD to get lost has been fixed, and the

1545 asynchronous subprocess, record the name of the input file name,
1547 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1548 delete the file, record it as pending deletion when the subprocess

1578 * dired.c (Ffile_attributes) [WINDOWSNT]:
1579 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1580 owner and group information from 'lstat'.
1582 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1584 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1585 as that confuses set-auto-coding, so insist on the head-read

1614 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1616 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1617 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1618 Remove unnecessary S_ISLNK test, as (contra the comments) this
1619 function can't copy symlinks. Improve quality of error message
1620 when attempting to copy files that are neither regular files nor

1639 * inotify.c (inotify_callback): Generate an Emacs event for every
1640 incoming inotify event.
1642 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1644 * xdisp.c (handle_face_prop): Fix logic of computing
1645 it->start_of_box_run_p.
1646 (append_space_for_newline): If the glyph row is R2L, reset the
1647 iterator's end_of_box_run_p flag before prepending the space glyph.

1649 iterator's start_of_box_run_p flag before prepending the stretch.

1896 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1897 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1898 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1899 (deleted_pid_list, Fdelete_process, create_process)
1900 (record_child_status_change, handle_child_signal, deliver_child_signal)
1901 (init_process_emacs, syms_of_process):
1902 Assume SIGCHLD is defined.
1903 (parse_signal): Remove. All uses removed.
1904 (abbr_to_signal): New static function.
1905 (Fsignal_process): Use it to convert signal names to ints.
1906 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1907 kill (getpgrp (), ...).
1908 (emacs_sigaction_init): Assume SIGCHLD is defined.
1909 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1910 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1911 * syssignal.h (EMACS_KILLPG): Remove.
1912 All uses replaced by 'kill' with a negative pid.
1913 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1914 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1916 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1918 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1919 This will cause a production Emacs to dump core instead of
1922 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1924 * frame.c (make_frame): Do not set window's buffer to t.
1925 * window.c (Fsplit_window_internal): Likewise. Previously it was
1926 used to indicate that the window is being set up. Now we use
1927 set_window_buffer for all new windows, so the condition in ...
1928 (Fset_window_buffer): ... is always true and can be removed.
1930 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1932 Convenient macro to check whether the buffer is hidden.
1933 * buffer.h (BUFFER_HIDDEN_P): New macro.
1934 * frame.c (make_frame): Use it. Adjust comment.
1935 * buffer.c (candidate_buffer): New function.
1936 (Fother_buffer, other_buffer_safely): Use it.
1938 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1940 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1941 if the child process is still running. Instead, exit the wait
1942 loop and return zero. (Bug#13086)
1944 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1946 * frame.h (x_char_width, x_char_height): Remove prototypes.
1947 * w32term.h (x_char_width, x_char_height): Likewise.
1948 * xfns.c (x_char_width, x_char_height): Remove.

1957 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1959 Fix a recently-introduced delete-process race condition.
1960 * callproc.c, process.h (record_kill_process):
1961 New function, containing part of the old call_process_kill.
1962 (call_process_kill): Use it.
1963 This does not change call_process_kill's behavior.
1964 * process.c (Fdelete_process): Use record_kill_process to fix a
1965 race condition that could cause Emacs to lose track of a child.
1967 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1969 Avoid code duplication between prev_frame and next_frame.
1970 * frame.c (candidate_frame): New function. Add comment.
1971 (prev_frame, next_frame): Use it. Adjust comment.
1973 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1975 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1976 fails, signal an error instead of continuing with an empty
1978 Encode expanded temp file pattern before passing it to mkstemp or
1981 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1982 Encode the file name before passing it to dostounix_filename, in
1983 case it will downcase it (under w32-downcase-file-names).
1986 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1988 Minor call-process cleanups.
1989 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1990 at the same time as other platforms, to simplify analysis.
1991 No need for fd0_volatile since we have synch_process_fd.
1992 Avoid needless emacs_close; arg is always negative.
1994 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1996 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1999 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2001 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2002 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2003 and mouse_face_hidden members to a bitfields.
2004 * frame.h (struct frame): Remove set-but-not-used space_width member.
2005 (FRAME_SPACE_WIDTH): Remove.
2006 * nsterm.m, w32term.c, xterm.c: Adjust users.
2007 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2008 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2009 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2010 members to a bitfields.
2012 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2014 Don't let call-process be a zombie factory (Bug#12980).
2015 Fixing this bug required some cleanup of the signal-handling code.
2016 As a side effect, this change also fixes a longstanding rare race
2017 condition whereby Emacs could mistakenly kill unrelated processes,
2018 and it fixes a bug where a second C-g does not kill a recalcitrant
2019 synchronous process in GNU/Linux and similar platforms.
2020 The patch should also fix the last vestiges of Bug#9488,
2021 a bug which has mostly been fixed on the trunk by other changes.
2022 * callproc.c, process.h (synch_process_alive, synch_process_death)
2023 (synch_process_termsig, sync_process_retcode):
2024 Remove. All uses removed, to simplify analysis and so that
2025 less consing is done inside critical sections.
2026 * callproc.c (call_process_exited): Remove. All uses replaced
2027 with !synch_process_pid.
2028 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2029 These take the role of what used to be in unwind-protect arg.
2031 (block_child_signal, unblock_child_signal):
2032 New functions, to avoid races that could kill innocent-victim processes.
2033 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2034 (call_process_kill): Record killed processes as deleted, so that
2035 zombies do not clutter up the system. Do this inside a critical
2036 section, to avoid a race that would allow the clutter.
2037 (call_process_cleanup): Fix code so that the second C-g works again
2038 on common platforms such as GNU/Linux.
2039 (Fcall_process): Create the child process in a critical section,
2040 to fix a race condition. If creating an asynchronous process,
2041 record it as deleted so that zombies do not clutter up the system.
2042 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2043 light of these changes. Omit unnecessary call to emacs_close
2044 before failure, as the unwind-protect code does that.
2045 * callproc.c (call_process_cleanup):
2046 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2047 * process.c (record_deleted_pid): New function, containing
2048 code refactored out of Fdelete_process.
2049 (Fdelete_process): Use it.
2050 (process_status_retrieved): Remove. All callers changed to use
2051 child_status_change.
2052 (record_child_status_change): Remove, folding its contents into ...
2053 (handle_child_signal): ... this signal handler. Now, this
2054 function is purely a handler for SIGCHLD, and is not called after
2055 a synchronous waitpid returns; the synchronous code is moved to
2056 wait_for_termination. There is no need to worry about reaping
2057 more than one child now.
2058 * sysdep.c (get_child_status, child_status_changed): New functions.
2059 (wait_for_termination): Now takes int * status and bool
2060 interruptible arguments, too. Do not record child status change;
2061 that's now the caller's responsibility. All callers changed.
2062 Reimplement in terms of get_child_status.
2063 (wait_for_termination_1, interruptible_wait_for_termination):
2064 Remove. All callers changed to use wait_for_termination.
2065 * syswait.h: Include <stdbool.h>, for bool.
2066 (record_child_status_change, interruptible_wait_for_termination):
2068 (record_deleted_pid, child_status_changed): New decls.
2069 (wait_for_termination): Adjust to API changes noted above.
2071 * bytecode.c, lisp.h (Qbytecode): Remove.
2072 No longer needed after 2012-11-20 interactive-p changes.
2074 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2076 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2077 the scroll margin, move point outside the margin. (Bug#13055)
2079 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2081 * gtkutil.c (my_log_handler): New function.
2082 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2084 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2086 * lisp.h (modify_region): Rename to...
2087 (modify_region_1): ...new prototype.
2088 * textprop.c (modify_region): Now static. Adjust users.
2089 * insdel.c (modify_region): Rename to...
2090 (modify_region_1): ...new function to work with current buffer.
2091 Adjust comment and users. Use true and false for booleans.
2093 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2095 * alloc.c (free_save_value): New function.
2096 (safe_alloca_unwind): Use it.
2097 * lisp.h (free_save_value): New prototype.
2098 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2100 (save_excursion_restore): Adjust to match saved data structure.
2101 Use free_save_value to offload some work from GC. Drop obsolete
2104 2012-12-03 Chong Yidong <cyd@gnu.org>
2106 * fileio.c (Vauto_save_list_file_name): Doc fix.
2108 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2110 * w32fns.c: Remove prototype of atof.
2111 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2113 (file_dialog_callback): Make it UINT_PTR.
2115 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2118 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2119 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2122 2012-12-03 Glenn Morris <rgm@gnu.org>
2124 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2126 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2128 Fix xpalloc confusion after memory is exhausted.
2129 * alloc.c (xpalloc): Comment fix.
2130 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2131 and signals an error, do not clear charset_table_size, as
2132 charset_table is still valid.
2133 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2135 Use execve to avoid need to munge environ (Bug#13054).
2136 * callproc.c (Fcall_process):
2137 * process.c (create_process):
2138 Don't save and restore environ; no longer needed.
2139 * callproc.c (child_setup):
2140 Use execve, not execvp, to preserve environ.
2142 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2144 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2146 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2148 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2149 display for sliced images (Bug#10500).
2151 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2153 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2155 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2156 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2158 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2160 * xdisp.c (window_outdated): Remove eassert since it hits
2161 some suspicious corner cases (see Bug#13007 and Bug#13012).
2162 (mode_line_update_needed): New function.
2163 (redisplay_internal, redisplay_window): Use it.
2164 (ensure_selected_frame): New function.
2165 (redisplay_internal, unwind_redisplay): Use it.
2166 (redisplay_internal): Move comment about buffer_shared...
2167 (buffer_shared_and_changed): ...near to its real use.
2169 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2171 * callproc.c (Fcall_process): Don't misreport vfork failure.
2173 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2175 * callproc.c (Fcall_process): Fix vfork portability problems.
2176 Do not assume that fd[0], count, filefd, and save_environ survive
2177 vfork. Fix bug whereby wrong errno value could be reported for
2178 pipe failure. Some minor cleanups, too, as follows. Move buf and
2179 bufsize to the context where they're needed. Change new_argv to
2180 be of type char **, as this is more convenient and avoids casts.
2181 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2182 Now local constants, not macros.
2184 2012-11-18 Kenichi Handa <handa@gnu.org>
2186 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2187 for the variable "f".
2189 2012-11-13 Kenichi Handa <handa@gnu.org>
2191 * font.c (font_unparse_xlfd): Exclude special characters from the
2192 generating XLFD name.
2194 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2196 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

2209 Assume EIO and EAGAIN are defined.
2210 * unexcoff.c (write_segment): Assume EFAULT is defined.
2212 2012-11-27 Eli Zaretskii <eliz@gnu.org>

2217 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2218 highlighting on the frame was cleared. Prevents assertion
2219 violations when repeatedly clicking on the "Top" link of the
2220 "bread-crumbs" in Info buffers.
2222 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2224 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.

2229 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2230 were always defined.
2232 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2234 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2235 between bpos_covered and bpos_max. This fixes cursor display when
2236 several display strings follow each other.
2238 * .gdbinit (pgx): If the glyph's object is a string, display the
2239 pointer to string data, rather than the value of the string object
2240 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2242 * indent.c (Fvertical_motion): If the starting position is covered
2243 by a display string, return to one position before that, to avoid
2244 overshooting it inside move_it_to. (Bug#12930)
2246 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2248 * frame.h (struct frame): Remove display_preempted member

2255 (struct w32_output): Use bitfields for explicit_parent,
2256 asked_for_visible and menubar_active members.
2257 Drop unused pending_menu_activation member.
2258 * xterm.h (struct x_output): Drop outdated #if 0 code.
2259 Use bitfields for explicit_parent, asked_for_visible,
2260 has_been_visible and net_wm_state_hidden_seen members.

2264 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2265 of a literal "/". (Bug#12955)
2266 (gl-stamp): Invoke fc.exe directly, not through cmd.
2268 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

2271 * dired.c: Assume HAVE_DIRENT_H.
2272 (NAMLEN): Remove, replacing with ...
2273 (dirent_namelen): New function. All uses changed. Use the GNU macro
2274 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2275 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2276 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2277 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2279 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2280 * ndir.h: Rename to ../nt/inc/dirent.h.
2281 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2282 Do not include <dirent.h>; no longer needed.
2283 * w32.c: Include <dirent.h> rather than "ndir.h".
2285 2012-11-23 Chong Yidong <cyd@gnu.org>
2287 * xftfont.c (xftfont_open): Remove duplicate assignment.
2289 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2291 * alloc.c (Fgarbage_collect): Unblock input after clearing
2292 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2293 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2294 * msdos.c (IT_frame_up_to_date): Use it here...
2295 * w32term.c (w32_frame_up_to_date): ...here...
2296 * xterm.c (XTframe_up_to_date): ...and here...
2297 * nsterm.m (ns_frame_up_to_date): ...but not here.
2298 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2300 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2301 Do not check whether GC is in progress.
2303 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2305 * xdisp.c (window_buffer_changed): New function.
2306 (update_menu_bar, update_tool_bar): Use it to
2307 simplify large 'if' statements.
2308 (redisplay_internal): Generalize commonly used
2309 'tail' and 'frame' local variables.
2311 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2313 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2314 with Windows system header.
2316 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2318 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2319 * alloc.c: Assume unistd.h exists.

2323 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2324 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2325 * w32.h (getcwd): Remove decl.
2327 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

2335 * emacs.c (main): Set the G_SLICE environment variable for all
2336 Cygwin builds, not just GTK builds. See
2337 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2339 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2341 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2342 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2343 Define for the MSVC compiler.
2345 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2347 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2348 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2349 dostounix_filename. Prevents crashes down the road, because
2350 dostounix_filename assumes it gets a unibyte string.

2358 * lread.c (init_obarray): Set `function' fields to Qnil.
2359 * eval.c (Fcommandp): Ignore Qunbound.
2360 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2361 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2362 Test NILP rather than Qunbound.
2363 (Ffmakunbound): Set to Qnil.
2364 (Fsymbol_function): Never signal an error.
2365 (Finteractive_form): Ignore Qunbound.
2367 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2369 * eval.c (interactive_p): Remove no-longer-used decl.
2371 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2373 * xdisp.c (buffer_shared): Adjust comment.
2374 (buffer_shared_and_changed): New function.
2375 (prepare_menu_bars, redisplay_internal): Use it to
2376 decide whether all windows or frames should be updated.
2377 (window_outdated): New function.
2378 (text_outside_line_unchanged_p, redisplay_window): Use it.
2379 (redisplay_internal): Likewise. Fix indentation.
2381 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2383 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2384 (syms_of_eval): Remove corresponding defsubr.
2385 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2387 2012-11-19 Daniel Colascione <dancol@dancol.org>
2389 * w32fns.c (Fx_file_dialog):
2390 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2391 cygwin_convert_file_name*.
2393 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2394 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2396 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2398 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2400 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2402 * w32select.c: Include w32common.h before w32term.h, so that
2403 windows.h gets included before w32term.h uses some of its
2404 features, see below.
2406 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2408 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2410 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2412 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2414 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2415 (ns_select): Return at once if events are held (Bug#12834).
2417 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2419 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2420 Needed following 2012-10-20 change. (Bug#12902)
2422 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2424 * w32proc.c (waitpid): Remove unused label get_result.
2426 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2428 * makefile.w32-in (SYSWAIT_H): New macro.
2429 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2430 ($(BLD)/sysdep.$(O)): Update dependencies.
2432 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2434 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2435 * callproc.c (relocate_fd): Assume F_DUPFD.
2436 * emacs.c, term.c (O_RDWR): Remove.
2437 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2438 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2439 * nsterm.m: Assume <fcntl.h> exists.
2440 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2441 (create_pty, Fmake_network_process, server_accept_connection)
2442 (wait_reading_process_output, init_process_emacs):
2444 (wait_reading_process_output): Put in a special case for WINDOWSNT
2445 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2446 It's not clear this is needed, but it's a more-conservative change.
2447 (create_process): Assume FD_CLOEXEC.
2448 (create_process, create_pty): Assume O_NOCTTY.
2449 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2450 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2451 Omit if not DOS_NT, since F_GETFL is not defined there.
2452 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2453 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2455 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2456 lack it, since gnulib guarantees this.
2457 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2459 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2461 * w32.c (faccessat): Pretend that directories have the execute bit
2462 set. Emacs expects that, e.g., in files.el:cd-absolute.
2464 * w32proc.c (create_child): Don't clip the PID of the child
2465 process to fit into an Emacs integer, as this is no longer a
2467 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2468 reaping only the process specified by PID argument, if that is
2469 positive. Use PID instead of dead_child to know which process to
2470 reap. Wait for the child to die only if WNOHANG is not in
2472 (sys_select): Don't set dead_child.
2474 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2475 as it is no longer needed.
2477 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2479 (record_child_status_change): Remove the setting of
2480 record_at_most_one_child for the !WNOHANG case.
2482 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2484 Fix problems in ns port found by static checking.
2485 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2486 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2487 not to process group.
2488 (ns_select): Use emacs_write, not write, as that's more robust
2489 in the presence of signals.
2490 (fd_handler:): Check for read errors.
2492 2012-11-16 Glenn Morris <rgm@gnu.org>
2494 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2496 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2498 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2500 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2502 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2503 use the same value of thread handle.
2504 (start_timer_thread): If the timer thread exited (due to error),
2505 clean up by closing the two handles it used. Duplicate the caller
2506 thread's handle here, so it gets duplicated only once, when
2507 launching the timer thread. Set priority of the timer thread, not
2509 (getitimer): Don't duplicate the caller thread's handle here.
2512 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2514 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2517 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2519 Remove no-longer-used pty_max_bytes variable.
2520 * process.c (pty_max_bytes): Remove; unused.
2521 (send_process): Do not set it.
2523 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2525 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2526 Update dependencies.
2528 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2530 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2531 This follows up on the 2012-09-29 patch that removed indirection
2532 for the 'function' field. Reported by Sergey Vinokurov in
2533 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2535 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2537 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2538 different name, as the MS runtime does not have such a function,
2539 and probably never will.) All callers changed. Ignore DIRFD
2540 value if PATH is an absolute file name, to match Posix spec
2541 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2544 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2546 * xdisp.c (echo_area_display, redisplay_internal):
2547 Omit redundant check whether frame_garbaged is set.
2549 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2551 Use faccessat, not access, when checking file permissions (Bug#12632).
2552 This fixes a bug that has been present in Emacs since its creation.
2553 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2554 which must set some sort of record. (Torek's bug report was against
2555 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2556 same common flaw.) See Torek's Usenet posting
2557 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2558 Posted: Fri Apr 8 14:18:56 1983.
2559 * Makefile.in (LIB_EACCESS): New macro.
2561 * callproc.c (init_callproc):
2562 * charset.c (init_charset):
2563 * fileio.c (check_existing, check_executable, check_writable)
2565 * lread.c (openp, load_path_check):
2566 * process.c (allocate_pty):
2568 Use effective UID when checking permissions, not real UID.
2569 * callproc.c (init_callproc):
2570 * charset.c (init_charset):
2571 * lread.c (load_path_check, init_lread):
2572 Test whether directories are accessible, not merely whether they exist.
2573 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2574 * fileio.c (check_existing, check_executable, check_writable)
2576 Use symbolic names instead of integers for the flags, as they're
2578 (check_writable): New arg AMODE. All uses changed.
2579 Set errno on failure.
2580 (Ffile_readable_p): Use faccessat, not stat + open + close.
2581 (Ffile_writable_p): No need to call check_existing + check_writable.
2582 Just call check_writable and then look at errno. This saves a syscall.
2583 dir should never be nil; replace an unnecessary runtime check
2584 with an eassert. When checking the parent directory of a nonexistent
2585 file, check that the directory is searchable as well as writable, as
2586 we can't create files in unsearchable directories.
2587 (file_directory_p): New function, which uses 'stat' on most platforms
2588 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2589 (Ffile_directory_p, Fset_file_times): Use it.
2590 (file_accessible_directory_p): New function, which uses a single
2591 syscall for efficiency.
2592 (Ffile_accessible_directory_p): Use it.
2593 * xrdb.c (file_p): Use file_directory_p.
2594 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2595 * lread.c (openp): When opening a file, use fstat rather than
2596 stat, as that avoids a permissions race. When not opening a file,
2597 use file_directory_p rather than stat.
2598 (dir_warning): First arg is now a usage string, not a format.
2599 Use errno. All uses changed.
2600 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2601 that merely introduced a race.
2602 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2603 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2604 and similarly for the other O_* flags.
2605 * w32.c (sys_faccessat): Rename from sys_access and switch to
2606 faccessat's API. All uses changed.
2607 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2608 (magic_db): Rename from magic_file_p.
2609 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2610 char *, so that we don't have to test for file existence
2611 separately from opening the file for reading. This removes a race
2612 fixes a permission-checking problem, and simplifies the code.
2614 (file_p): Remove; no longer needed.
2616 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2618 Omit glyphs initialization at startup.
2619 * dispnew.c (glyphs_initialized_initially_p): Remove.
2620 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2621 (Fredraw_frame): Move actual code from here...
2622 (redraw_frame): ...to here. Add eassert. Adjust comment.
2623 (Fredraw_display): Use redraw_frame.
2624 * xdisp.c (clear_garbaged_frames): Likewise.
2626 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2628 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2629 passed to pint2str and pint2hrstr to be at most the size of the
2630 frame's decode_mode_spec_buffer. This avoids crashes with very
2631 large values of FIELD_WIDTH argument to decode_mode_spec.
2634 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2636 Fix a race with verify-visited-file-modtime (Bug#12863).
2637 Since at least 1991 Emacs has ignored an mtime difference of no
2638 more than one second, but my guess is that this was to work around
2639 file system bugs that were fixed long ago. Since the race is
2640 causing problems now, let's remove that code.
2641 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2642 whose time stamp is off by no more than a second. Insist that the
2643 file time stamps match exactly.
2645 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2647 * frame.h (struct frame): Convert external_tool_bar member to
2648 1-bit unsigned bitfield.
2649 * termhooks.h (struct terminal): Remove mouse_moved member since
2650 all users are long dead. Adjust comment on mouse_position_hook.
2652 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2654 Simplify by using FOR_EACH_FRAME here and there.
2655 * frame.c (next_frame, prev_frame, other_visible_frames)
2656 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2657 * w32term.c (x_window_to_scroll_bar): Likewise.
2658 * window.c (window_list): Likewise.
2659 * xdisp.c (x_consider_frame_title): Likewise.
2660 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2661 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2662 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2663 * xmenu.c (menubar_id_to_frame): Likewise.
2664 * xselect.c (frame_for_x_selection): Likewise.
2665 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2666 (x_window_to_menu_bar): Likewise.
2667 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2669 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2671 * data.c (Qdefalias_fset_function): Now static.
2673 Another tweak to vectorlike_header change.
2674 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2675 Remove, and replace all uses with ...
2676 (next_in_free_list, set_next_in_free_list):
2677 New functions, which respect C's aliasing rules better.
2679 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2681 * window.c (list4i): Rename from 'quad'. All uses changed.
2682 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2684 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2686 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2687 warning about mixing declarations and code in ISO C90.
2689 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2691 * window.c (Fsplit_window_internal): Set combination limit of
2692 new parent window to t iff Vwindow_combination_limit is t;
2693 fixing a regression introduced with the change from 2012-09-22.
2694 (Fset_window_combination_limit): Fix doc-string.
2696 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2698 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2699 amount when the scroll margins are too large. When scrolling
2700 backwards in the buffer, give up if cannot reach point or the
2701 scroll margin within a reasonable number of screen lines.
2702 Fixes point position in window under scroll-up/down-aggressively when
2703 point is positioned many lines beyond the window top/bottom.
2706 * ralloc.c (relinquish): If real_morecore fails to return memory
2707 to the system, don't crash; instead, leave the last heap
2708 unchanged and return. (Bug#12774)
2710 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2712 * lisp.h (AUTOLOADP): New macro.
2713 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2714 * data.c (Ffset): Remove special ad-advice-info handling.
2715 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2717 (Finteractive_form): Simplify.
2718 (Fquo): Don't insist on having at least 2 arguments.
2719 (Qdefalias_fset_function): New var.
2721 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2723 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2727 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2729 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2731 Fix recently introduced crash on MS-Windows (Bug#12839).
2732 * w32term.h (struct scroll_bar): Use convenient header.
2733 (SCROLL_BAR_VEC_SIZE): Remove.
2734 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2736 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2738 Tweak last vectorlike_header change.
2739 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2740 vectorlike object on the free list. This is introduced to avoid
2741 some (but not all) pointer casting and aliasing problems, see
2742 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2743 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2745 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2747 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2749 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2750 been removed, so remove them here also.
2752 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2754 * doc.c (Fdocumentation): Handle new property
2755 dynamic-docstring-function to replace the old ad-advice-info.
2757 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2759 * fns.c (Qeql, hashtest_eq): Now static.
2761 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2763 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2764 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2765 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2766 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2768 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2770 Use same hash function for hashfn_profiler as for hash_string etc.
2771 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2772 * lisp.h (sxhash_combine): New inline function, with the contents
2773 of the old SXHASH_COMBINE.
2774 * profiler.c (hashfn_profiler): Use it, instead of having a
2775 special hash function containing a comparison that always yields 1.
2777 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2779 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2780 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2781 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2784 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2786 * image.c (xpm_make_color_table_h): Fix compiler error because
2787 make_hash_table changed.
2789 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2791 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2793 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2795 Use ad-hoc comparison function for the profiler's hash-tables.
2796 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2797 (make_log): Use them.
2798 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2799 call Fequal any more.

2808 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2809 (hash_lookup, hash_remove_from_table): Move assertion checking of
2810 hashfn result here. Check hash-equality before calling cmpfn.
2811 (Fmake_hash_table): Adjust call to make_hash_table.
2812 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2813 (syms_of_fns): Initialize them.

2818 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2820 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2822 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2823 value of w32-scroll-lock-modifier is neither nil nor one of the
2824 known key modifiers. (Bug#12806)
2826 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2828 Shrink struct vectorlike_header to the only size field.
2829 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2831 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2832 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2833 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2834 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2835 information from the vector header. Adjust comment.

2845 (enum mem_type): Adjust comment.
2846 (NEXT_IN_FREE_LIST): New macro.
2847 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2848 (Fmake_bool_vector): Likewise.
2849 (struct large_vector): New type to represent allocation unit for
2850 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2851 (large_vectors): Change type to struct large_vector.
2852 (allocate_vector_from_block): Simplify.
2853 (PSEUDOVECTOR_NBYTES): Replace with...
2854 (vector_nbytes): ...new function. Adjust users.
2855 (sweep_vectors): Adjust processing of large vectors.
2856 (allocate_vectorlike): Likewise.
2857 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2858 Add easserts. Adjust XSETPVECTYPESIZE usage.
2859 (allocate_buffer): Use BUFFER_PVEC_INIT.
2860 (live_vector_p): Adjust to match large vector.
2861 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2862 * buffer.h (struct buffer): Add next member.
2863 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2865 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2866 * fns.c (internal_equal): Adjust to match enum pvec_type change.

2871 (xvecsize): New command.
2873 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2875 * keyboard.c (event_to_kboard): Do not dereference
2876 frame_or_window field of SELECTION_REQUEST_EVENT
2877 and SELECTION_CLEAR_EVENT events (Bug#12814).
2878 * xterm.h (struct selection_input_event): Adjust comment.
2880 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2882 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2883 such as Scroll Lock, if the respective keys are treated as
2884 function keys, not as modifiers. This avoids destroying non-ASCII
2885 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2887 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2889 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2891 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2893 Restore some duplicate definitions (Bug#12814).
2894 This undoes part of the 2012-11-03 changes. Some people build
2895 with plain -g rather than with -g3, and they need the duplicate
2896 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2897 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2898 Define as macros, as well as as enums or as constants.
2900 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2902 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2903 to keypad keys (Bug#12816).
2905 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2907 Minor adjustments of recently-changed frame functions.
2908 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2909 known to be a frame (we're in the FRAMEP branch).
2910 * lisp.h (Qframep): Remove decl. frame.h declares this.
2911 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2912 since they're meant for Lisp fixnum values.
2914 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2916 * window.c (Fwindow_combination_limit): Revert to the only
2917 required argument and adjust docstring as suggested in
2918 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2919 by Martin Rudalics <rudalics@gmx.at>.
2921 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2923 Widely used frame validity and checking functions.
2924 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2925 * frame.c (decode_live_frame, decode_any_frame): New functions.
2926 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2927 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2928 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2929 (Fframe_pointer_visible_p): Use decode_any_frame.
2930 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2931 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2932 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2933 (Fframe_focus): Likewise. Allow zero number of arguments.
2935 (frame_buffer_list, frame_buffer_predicate): Remove.
2936 * lisp.h (frame_buffer_predicate): Remove prototype.
2937 * buffer.c (Fother_buffer): Use decode_any_frame.
2938 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2939 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2940 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2941 (Fclose_font, Ffont_info): Use decode_live_frame.
2942 * fontset.c (check_fontset_name): Likewise.
2943 * terminal.c (Fframe_terminal): Likewise.
2944 * w32fns.c (check_x_frame): Likewise.
2945 * window.c (Fminibuffer_window, Fwindow_at)
2946 (Fcurrent_window_configuration): Likewise.
2947 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2948 Likewise. Allow zero number of arguments. Adjust docstring.
2949 * dispnew.c (Fredraw_frame): Likewise.
2950 * xfaces.c (frame_or_selected_frame): Remove.
2951 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2952 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2953 (Fframe_face_alist): Use decode_live_frame.
2954 * xfns.c (check_x_frame): Likewise.
2956 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2958 * window.c (quad): New function.
2959 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2960 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2961 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2962 (Fwindow_line_height): Use it.
2963 (Fwindow_fringes): Use list3.
2964 (Fwindow_scroll_bars): Use list4.
2965 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2966 (Fwindow_combination_limit): Allow zero number of arguments.
2968 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2970 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2972 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2973 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2974 file descriptor 2 for standard error. (Bug#12805)
2976 2012-11-05 Chong Yidong <cyd@gnu.org>
2978 * process.c (wait_reading_process_output): Revert previous change.
2980 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2982 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2983 This removes code that has been obsolete since around 1990.
2984 * callproc.c (Fcall_process):
2986 * process.c (create_process):
2987 * term.c (dissociate_if_controlling_tty):
2988 Assume setsid exists.
2989 * callproc.c (child_setup): Assume setpgid exists and behaves as
2990 per POSIX.1-1988 or later.
2991 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2992 * emacs.c (shut_down_emacs):
2993 * sysdep.c (sys_suspend, init_foreground_group):
2994 Assume getpgrp behaves as per POSIX.1-1998 or later.
2995 * msdos.c (setpgrp): Remove.
2996 (tcgetpgrp, setpgid, setsid): New functions.
2997 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2998 * term.c (no_controlling_tty): Remove; unused.
2999 * w32proc.c (setpgrp): Remove.
3000 (setsid, tcgetpgrp): New functions.
3002 Simplify by assuming __fpending.
3003 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3004 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3005 Do not assume that __fpending's result fits in int.
3007 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3009 Remove EMACS_OUTQSIZE+sleep hack.
3010 * dispnew.c (update_frame_1): Remove hack for terminals slower
3011 than 2400 bps, which throttled Emacs by having it sleep.
3012 This code hasn't worked since at least 2007, when the multi-tty stuff
3013 was added, and anyway those old terminals are long dead.
3014 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3015 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3017 Fix data-loss with --version (Bug#9574).
3018 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3019 as we can't assume that emacs_strerror is initialized, and strerror
3020 is good enough here.
3021 (main): Invoke atexit earlier, to catch earlier instances of
3022 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3024 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3026 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3027 (keyDown): Remap keypad keys to X11 virtual key codes.
3029 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3031 Fix data-loss with --batch (Bug#9574).
3032 * emacs.c: Include <close-stream.h>.
3033 (close_output_streams): New function.
3034 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3035 and handles errors appropriately.
3036 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3039 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3040 The symptom is a diagnostic "GLib-WARNING **: In call to
3041 g_spawn_sync(), exit status of a child process was requested but
3042 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3043 waitpid(), so exit status can't be returned." The diagnostic
3044 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3045 The real bug is a race condition between Emacs and glib: Emacs
3046 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3047 so that glib can't find it. Work around the bug by invoking
3048 waitpid only on subprocesses that Emacs itself creates.
3049 * process.c (create_process, record_child_status_change):
3050 Don't use special value -1 in pid field, as the caller now must
3051 know the pid rather than having the callee infer it.
3052 The inference was sometimes incorrect anyway, due to another race.
3053 (create_process): Set new 'alive' member if child is created.
3054 (process_status_retrieved): New function.
3055 (record_child_status_change): Use it.
3056 Accept negative 1st argument, which means to wait for the
3057 processes that Emacs already knows about. Move special-case code
3058 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3059 processes that have already been waited for, by testing and
3060 clearing new 'alive' member.
3061 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3062 now does this internally.
3063 (handle_child_signal): Let record_child_status_change do all
3064 the work, since we do not want to reap all exited child processes,
3065 only the child processes that Emacs itself created.
3066 * process.h (Lisp_Process): New boolean member 'alive'.
3068 Omit duplicate definitions no longer needed with gcc -g3.
3069 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3070 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3071 Define only as macros. There's no longer any need to also define
3072 these symbols as enums or as constants, since we now assume
3073 gcc -g3 when debugging.
3075 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3077 * lisp.mk: Adjust comments to the fact that term/internal is now
3078 loaded from loadup.el.
3080 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3081 (msdos_fatal_signal): New function.
3082 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3085 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3086 for GCC versions before 4.
3087 (emacs_raise): Define to call msdos_fatal_signal.
3089 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3090 iterator when starting in the middle of a display or overlay
3093 2012-11-03 Chong Yidong <cyd@gnu.org>
3095 * process.c (wait_reading_process_output): Clean up the last
3098 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3100 * process.c (wait_reading_process_output): Avoid a race condition
3101 with SIGIO delivery (Bug#11536).
3103 2012-11-03 Chong Yidong <cyd@gnu.org>
3105 * buffer.c (cursor_type): Untabify docstring.
3107 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3109 * frame.h (struct frame): Drop can_have_scroll_bars member
3110 which is meaningless for a long time. Adjust comments.
3111 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3112 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3114 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3116 * window.c (decode_next_window_args): Update window arg after
3117 calling decode_live_window and so fix crash reported at
3118 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3119 by Juanma Barranquero <lekktu@gmail.com>.
3120 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3121 * font.c (Ffont_at): Likewise.
3123 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3125 * widget.c (resize_cb): New function.
3126 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3127 (EmacsFrameResize): Check if all is up to date before changing frame
3130 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3132 Implement backtrace output for fatal errors on MS-Windows.
3133 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3134 (BACKTRACE_LIMIT_MAX): New macro.
3135 (w32_backtrace): New function.
3136 (emacs_abort): Use w32_backtrace when the user chooses not to
3137 attach a debugger. Update the text of the abort dialog.
3139 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3141 Window-related stuff cleanup here and there.
3142 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3143 Use decode_any_window.
3144 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3145 * xdisp.c (Fformat_mode_line): Likewise.
3146 * font.c (Ffont_at): Use decode_live_window.
3147 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3148 * window.c (decode_next_window_args): Likewise.
3149 (decode_any_window): Remove static.
3150 * window.h (decode_any_window): Add prototype.
3151 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3152 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3155 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3157 Remove pad from struct input_event.
3158 * termhooks.h (struct input_event): Remove padding field.
3160 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3161 member is never cons for a long time. Adjust comment.
3162 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3163 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3164 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3165 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3167 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3169 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3171 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3173 Fix crash when using Emacs as commit editor for git (Bug#12697).
3174 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3175 and it is configured in conf_post.h.
3176 (Fcall_process): Don't invoke both setsid and setpgid; the former
3177 is enough, if it exists.
3178 * callproc.c (Fcall_process, child_setup):
3179 * process.c (create_process): Use setpgid.
3180 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3182 * dispnew.c (init_display): Initialize the foreground group
3183 if we are running a tty display.
3184 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3185 * lisp.h (init_foreground_group): New decl.
3186 * sysdep.c (inherited_pgroup): New static var.
3187 (init_foreground_group, tcsetpgrp_without_stopping)
3188 (narrow_foreground_group, widen_foreground_group): New functions.
3189 (init_sys_modes): Narrow foreground group.
3190 (reset_sys_modes): Widen foreground group.
3192 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3194 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3196 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3198 * minibuf.c (read_minibuf): Restore current buffer since
3199 choose_minibuf_frame calling Fset_frame_selected_window may
3200 change it (Bug#12766).
3202 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3204 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3206 2012-10-30 Kenichi Handa <handa@gnu.org>
3208 * font.c (Ffont_at): If WINDOW is specified and it is not
3209 displaying the current buffer, signal an error.
3211 2012-10-29 Daniel Colascione <dancol@dancol.org>
3213 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3214 In preparation for fixing bug#12739, move these functions from
3217 * coding.h, coding.c: ... to here, and compile them only when
3218 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3219 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3221 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3223 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3224 (timer_loop, getitimer, setitimer): Use it instead of
3225 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3227 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3230 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3232 * nsterm.m (NO_APPDEFINED_DATA): New define.
3233 (last_appdefined_event_data): New variable
3234 (last_appdefined_event): Remove.
3235 (ns_select): Initialize t from last_appdefined_event_data instead
3236 of [last_appdefined_event data1].
3237 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,

3242 * frame.c (x_set_font): Catch internal error.
3244 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3246 Avoid overflow in w32 implementation of interval timers.
3247 When possible, for ITIMER_PROF count only times the main thread
3249 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3250 'volatile ULONGLONG' types. All the other data which was
3251 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3252 (GetThreadTimes_Proc): New typedef.
3253 (w32_get_timer_time): New function, returns a suitable time value
3255 (timer_loop): Enter critical section when accessing ULONGLONG
3256 values of the itimer_data struct, as these accesses are no longer
3257 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3258 Remove unused variable.
3259 (init_timers): Initialize s_pfn_Get_Thread_Times.
3260 (start_timer_thread): Don't assign itimer->caller_thread here.
3261 (getitimer): Assign itimer->caller_thread here.

3267 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3268 mouse movement events if the menu bar is active. This avoids
3269 producing a busy "hour-glass" cursor by Windows if the mouse
3270 pointer is positioned over a tooltip shown for some menu item.
3272 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3274 Don't assume process IDs fit in int.
3275 * emacs.c (shut_down_emacs) [!DOS_NT]:
3276 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3277 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3278 Use pid_t, not int, to store process IDs, as 'int'
3279 is not wide enough on a few platforms (e.g., AIX and IRIX).
3281 2012-10-23 Kenichi Handa <handa@gnu.org>
3283 The following change is to make face-font-rescale-alist work
3284 correctly for non-ASCII fonts.

3306 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3308 Port to OpenBSD 5.1.
3309 * frame.c (Fmouse_position, Fmouse_pixel_position):
3310 * xdisp.c (produce_stretch_glyph):
3311 Declare local vars only when they're needed.
3312 This is clearer and avoids a warning on OpenBSD about unused vars.

3314 This is safer, and avoids OpenBSD warnings about unused vars.
3315 * keyboard.c (record_menu_key): Remove unnecessary decl.
3316 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3317 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3318 as our definition clashes with OpenBSD's.
3319 * xfaces.c (load_face_colors, check_lface_attrs)
3320 (get_lface_attributes_no_remap, get_lface_attributes)
3321 (lface_fully_specified_p, x_supports_face_attributes_p)
3322 (tty_supports_face_attributes_p, face_fontset, realize_face)
3323 (realize_x_face, realize_tty_face):
3324 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3325 merely Lisp_Object *. This is more informative and avoids
3326 a warning on OpenBSD about accessing beyond an object's size.
3328 2012-10-20 Chong Yidong <cyd@gnu.org>
3330 * lread.c (Fload): Doc fix (Bug#12592).

3356 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3357 (staticpro): If we run out of staticpro slots, die with an
3358 informative error instead of just calling emacs_abort.
3360 2012-10-18 Martin Rudalics <rudalics@gmx.at>

3620 the same pointer-to-int (now pointer-to-boolean) &input_pending,

3673 2012-10-08 Daniel Colascione <dancol@dancol.org>
3675 * xdisp.c (start_hourglass): Call w32_note_current_window when

3677 build that caused Emacs to display the hourglass cursor forever.
3679 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3680 which is broken under remote desktop, calculate the number of
3681 colors available for a display based on the display's number of

3717 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3719 2012-10-08 Daniel Colascione <dancol@dancol.org>
3721 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3722 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3723 accidental message numbering hole. Change other messages to
3726 * w32select.h (HAVE_W32SELECT): Remove.
3728 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3729 w32common.h instead of w32heap.h.
3731 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3732 (get_allocation_unit, get_processor_type, get_w32_major_version)
3733 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3734 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3735 (OS_NT, os_subtype, cache_system_info): Move declarations to
3738 * w32heap.c: Include w32common.h.
3739 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3740 (w32_minor_version, w32_build_number, w32_subtype):
3741 Remove duplicate definitions.
3743 * w32fns.c: Include w32common.h; include w32heap.h only in
3746 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3747 Use `report_file_error' instead of `error' in order to better
3748 inform users of what went wrong. Increase NTGUI_UNICODE file
3749 dialog box file name length to 32k, the maximum allowed by the NT
3752 * w32common.h: New file.
3753 (ROUND_UP, ROUND_DOWN, get_page_size)
3754 (get_allocation_unit, get_processor_type, get_w32_major_version)
3755 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3756 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3757 (OS_NT, os_subtype, cache_system_info): Move here.
3759 * unexw32.c, unexcw.c: Include w32common.h.
3761 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3762 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3763 to call syms_of_w32select.
3765 * cygw32.h: Remove obsolete EXFUN declarations.
3767 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3769 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3770 of w32inevt.o from SOME_MACHINE_OBJECTS.
3772 2012-10-08 Daniel Colascione <dancol@dancol.org>
3774 * image.c: Permanent fix for JPEG compilation issue --- limit
3775 jpeglib `boolean' redefinition to Cygwin builds.
3777 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3779 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3781 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3784 2012-10-08 Daniel Colascione <dancol@dancol.org>
3786 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3787 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3788 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3789 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3790 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3791 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3792 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3793 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3794 now a supported configuration.
3796 * Makefile.in: consolidate image variables into LIBIMAGE; add
3797 W32_OBJ and W32_LIBS. Compile new files.
3800 (_DebPrint) declare tracing facility for W32 debugging. We need
3801 to unify tracing later.
3803 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3804 unconditional use of W32 Unicode functions. Cygwin runs only on
3805 100% Unicode operating systems.
3807 * cygw32.c: New file. Define Cygwin-specific facilities.
3808 (Fcygwin_convert_path_to_windows)
3809 (Fcygwin_convert_path_from_windows): New user functions for
3810 accessing Cygwin path-munging routines.
3812 * cygw32.h: New file.
3813 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3814 UTF-16LE strings temporarily inside non-Lisp-visible string
3817 (w32_strerror): Just what it says on the tin.
3819 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3820 also run for Cygwin; both systems have the same problem with using
3821 GUI facilities in a forked child. Also call syms_of_cygw32,
3822 syms_of_w32select in correct places.
3824 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3825 needs fork-then-exec for daemon launching.
3827 * font.h: Include frame.h.
3829 * image.c: Use the image library cache machinery only when we're
3830 compiling for native WINDOWSNT; Cygwin can use shared libraries
3831 like any other Unixlike system.
3833 * keyboard.c: Clarify a comment regarding the input loop.
3835 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3836 functions directly instead of trying to detect at runtime that our
3837 host operating system supports them. We make this change for two
3838 reasons: Cygwin lacks support for the multibyte character
3839 conversion functions used by the legacy menu code, and Cygwin
3840 never needs to rely on non-Unicode APIs.
3842 * unexw32.c (hinst): Declare extern.
3844 * w32.c: Change header order;
3845 (w32_strerror): Move to w32fns.c because we need it for
3846 non-WINDOWSNT builds.
3848 * w32.h: Add #error macro to make sure we don't include w32.h for
3849 Cygwin builds. Remove w32select declarations.
3851 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3852 w32fns.c. w32console.c is WINDOWSNT-only.
3854 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3855 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3857 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3858 (w32_major_version, w32_minor_version, w32_build_number)
3859 (os_subtype, sound_type): Define here
3860 (w32_defined_color): Make color parameter const for consistency
3861 with other _defined_color functions.
3862 (w32_createwindow): Unconditionally call w32_init_class instead of
3863 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3864 through the code is complex and unnecessary because class
3865 registration is practically free.
3866 (w32_name_of_message): New EMACSDEBUG-only function.
3867 (Fset_message_beep): Move here
3868 (Fx_open_connection): Require that the display name for Windows be
3869 "w32" for consistency, emacsclient disambiguation, and maybe, one
3870 day, multi-window-system support.
3871 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3872 Cygwin files for W32 GUI facilities, since these clearly don't
3873 expect Cygwin names.
3874 (_DebPrint): Define.
3875 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3876 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3877 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3878 (w32_last_error): Remove.
3880 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3882 * w32heap.c (syspage_mask): Declare here.
3883 (cache_system_info): Remove.
3885 * w32inevt.c (faked_key): Define globally, not statically.
3886 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3887 (w32_console_toggle_lock_key): Move to w32fns.c.
3889 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3891 * w32proc.c (_DebPrint): Move to w32fns.c.
3892 * w32select.c: Include string.h, stdio.h for Cygwin.
3893 * w32select.h: New File.
3895 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3897 (w32_message_fd): New variable. Under Cygwin, holds the file
3898 descriptor the system used to tell us about pending thread
3901 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3902 that prevented compilation under non-WINDOWSNT systems.
3904 (w32_initialize): Open /dev/windows and assign it to
3905 w32_message_fd. Provide w32 feature.
3907 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3908 (WM_EMACS_INPUT_READY): add.
3909 (prepend_msg, w32_message_fd): Declare globally.
3912 (keyboard_handle): Use only when WINDOWSNT.
3913 (notify_msg_ready): New function. Posts a message to the main
3914 thread's message queue under CYGWIN, which wakes up the main
3915 thread from select(2) by making the /dev/windows file descriptor
3916 ready. Under WINDOWSNT, it sets an event the same way the old
3919 (post, prepend_msg): Actually call notify_msg_ready instead of
3920 setting the input event directly.
3922 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3924 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3925 but it still has blocs in it, don't return it to the system,
3926 instead of aborting. (Bug#12402)
3928 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3930 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3932 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3933 MAC_OS_X_VERSION_10_6.
3934 (syms_of_nsterm): Remove comment about Panther and above for
3936 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3937 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3938 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3940 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3941 MAC_OS_X_VERSION_10_4.
3943 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3944 MAC_OS_X_VERSION_10_2.
3946 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3948 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3949 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3951 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3952 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3953 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3954 Remove ns_in_resize check.
3955 (ns_clear_frame_area): Remove resize handle code.
3957 * nsfns.m (ns_in_resize): Remove.
3958 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3959 Remove ns_in_resize check.
3961 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3963 Improve sys_siglist detection.
3964 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3965 defined as a macro, as is done in Solaris.
3966 (sys_siglist_entries): New macro.
3967 (save_strsignal): Use it.
3968 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3969 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3971 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3973 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3974 fullscreen/Fullscreen.
3976 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3977 tobar_height is new.
3979 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3980 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3981 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3982 (windowDidResize:): Check for correct window if old style fullscreen.
3983 Capitalize word in comment. Remove incorrect comment.
3984 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3985 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3986 error in drawing background.
3987 (toggleFullScreen:): Remove comment. Rearrange calls.
3988 Set toolbar values to zero, save old height in tobar_height.
3989 Restore tool bar height when leaving fullscreen.
3990 (canBecomeMainWindow): New function.
3992 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3994 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3996 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3998 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4000 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4001 that time stamps of directories could also be changed.
4002 Don't request the too broad GENERIC_WRITE, only the more restrictive
4003 FILE_WRITE_ATTRIBUTES access rights.
4005 * fileio.c (Fset_file_times): Special-case ignoring errors for
4006 directories only on MSDOS, not on MS-Windows.
4008 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4010 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4012 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4014 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4015 see whether CreateFile failed.
4017 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4019 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4020 to avoid similar races.
4021 * keyboard.c (pending_signals): Now bool, not int.
4023 Port timers to OpenBSD, plus check for timer failures.
4024 OpenBSD problem reported by Han Boetes.
4025 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4027 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4028 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4029 like OpenBSD, which has timer_settime but does not declare it.
4030 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4031 whether to use itimerspec-related primitives. All uses of
4032 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4034 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4036 * profiler.c (handle_profiler_signal): Fix a malloc race
4037 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4039 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4041 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4043 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4045 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4046 consistent with the change in return value of 'safe_strsignal'.
4048 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4050 Prefer plain 'static' to 'static inline' (Bug#12541).
4051 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4052 (bidi_set_sor_type, bidi_push_embedding_level)
4053 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4054 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4055 (bidi_cache_search, bidi_cache_ensure_space)
4056 (bidi_cache_iterator_state, bidi_cache_find)
4057 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4058 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4059 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4060 Now 'static', not 'static inline'.
4062 Count overruns when profiling; change units to ns.
4063 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4064 Give extra weight to samples after overruns, to attempt to count
4065 the time more accurately.
4066 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4067 the underlying primitives nominally do ns.
4068 (Fprofiler_cpu_start): Document the change. Mention that
4069 the sampling intervals are only approximate.
4071 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4073 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4075 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4076 case for the special 0 coding-system.
4078 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4079 (Fmake_overlay): Remove redundant tests.
4080 (fix_start_end_in_overlays): Remove redundant recentering.
4082 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4084 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4085 Update dependencies.
4087 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4089 Fix a malloc race condition involving strsignal.
4090 A signal can arrive in the middle of a malloc, and Emacs's signal
4091 handler can invoke strsignal, which can invoke malloc, which is
4092 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4093 Fix it by altering the signal handler so that it does not invoke
4095 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4096 * process.c (status_message): Use const pointer, in case strsignal
4097 is #defined to safe_strsignal.
4098 * sysdep.c (sys_siglist, init_signals): Always define and
4099 initialize a substitute sys_siglist if the system does not define
4100 one, even if HAVE_STRSIGNAL.
4101 (safe_strsignal): Rename from strsignal. Always define,
4102 using sys_siglist. Return a const pointer.
4103 * syssignal.h (safe_strsignal): New decl.
4104 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4106 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4108 * w32proc.c (timer_loop): Fix code that waits for timer
4109 expiration, to avoid high CPU usage.
4111 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4113 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4114 (sweep_weak_table): Remove redundant prototypes.
4116 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4118 * emacs.c: Move the inclusion of TERM_HEADER after including
4119 windows.h on WINDOWSNT. This avoids compilation problems with
4122 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4124 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4125 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4126 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4127 as the previous version used 'void *'.
4129 * ralloc.c (ROUNDUP): Fix last change.
4130 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4133 * w32proc.c <disable_itimers>: New static flag.
4134 (init_timers): Initialize it to zero, after creating the critical
4135 sections used by the timer threads.
4136 (term_timers): Set to 1 before deleting the critical sections.
4137 (getitimer, setitimer): If disable_itimers is non-zero, return an
4138 error indication without doing anything. Reported by Fabrice
4139 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4140 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4142 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4145 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4146 term_ntproc after all the other bookkeeping, to get timers working
4147 as long as possible.
4149 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4151 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4152 Suggested by Juri Linkov in
4153 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4155 Prefer plain 'static' to 'static inline' (Bug#12541).
4156 With static functions, modern compilers inline pretty well by
4157 themselves; advice from programmers often hurts as much as it helps.
4158 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4159 this change shrinks the text size of the Emacs executable by 1.1%
4160 without affecting CPU significantly in my benchmark.
4161 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4162 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
4163 (mark_maybe_object, mark_maybe_pointer, bounded_number):
4164 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
4165 (bset_auto_fill_function, bset_auto_save_file_format)
4166 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

4454 (handle_profiler_signal): Rename from sigprof_handler_1,
4455 for consistency with other handlers. Do not check whether
4456 cpu_log is a hash-table if garbage collecting, since it

4459 for consistency with other handlers.
4460 (setup_cpu_timer): New function, with much of what used to be in

4462 Prefer timer_settime if available, and prefer
4463 thread cputime clocks, then process cputime clocks, then
4464 monotonic clocks, to the old realtime clock. Use make_timeval
4465 to round more-correctly when falling back to setitimer.
4466 (Fprofiler_cpu_start): Use it.
4467 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4474 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4475 in profiler.c, since sysdep.c now uses it.
4477 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4533 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4534 Since this stuff is now private to charset.c, there's no need for
4535 a public macro and no need to inline by hand.

4609 (sys_kill): Improve commentary.
4611 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4612 consistency with a signature of a signal handler. All callers
4614 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4615 install term_ntproc as a signal handler for SIGABRT, as that
4616 should be done by the dumped Emacs.

4621 invocation by setting clipboard_owner to NULL after calling

4645 now return bool, not int. All uses changed.
4646 * image.c: Omit unnecessary static decls.
4647 (x_create_bitmap_mask, x_build_heuristic_mask):
4648 Return void, not int, since callers don't care about the return value.

4683 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4685 Move pid_t related decls out of lisp.h.
4686 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4687 (interruptible_wait_for_termination):
4688 Move these decls from lisp.h to syswait.h, since they use pid_t.
4689 Needed on FreeBSD; see Herbert J. Skuhra in
4690 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4691 * callproc.c: Include syswait.h.

4711 Use bool for boolean.
4712 * gtkutil.c (xg_update_frame_menubar):

4737 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4739 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4740 fatal_error_backtrace.
4742 * w32proc.c (sys_kill): Undo last change: don't do anything when
4743 invoked to deliver SIGABRT to our own process. This is now
4744 handled by emacs_raise.
4746 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4748 * w32term.c (w32_read_socket): Remove leftover reference to
4749 interrupt_input_pending.
4751 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4753 Do not use SA_NODEFER.
4754 Problem reported by Dani Moncayo in
4755 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4757 * sysdep.c (emacs_abort): Do not reset signal handler.
4758 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4759 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4760 wanted even on POSIXish hosts, and it doesn't work on Windows.
4762 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4764 * xterm.c (x_term_init): Call fixup_locale before and after calling
4765 gtk_init (Bug#12392).
4767 2012-09-23 Chong Yidong <cyd@gnu.org>
4769 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4770 Vdynamic_library_alist.
4772 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4773 (Fgnutls_available_p): Caller changed.
4775 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4776 (Flibxml_parse_xml_region): Likewise.
4778 * dispextern.h (struct image_type): Remove arg from init function.
4780 * image.c (Finit_image_library, lookup_image_type)
4781 (define_image_type): Remove now-unneeded second arg.
4782 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4783 (init_tiff_functions, init_gif_functions, init_svg_functions):
4784 Arglist and w32_delayed_load calling convention changed.
4785 (gs_type): Remove init_gs_functions; there is no such function.
4786 (valid_image_p, make_image): Fix caller to lookup_image_type.
4788 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4790 Simplify and avoid signal-handling races (Bug#12471).
4792 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4793 Avoid recursive loop if there's a fatal error in the function itself.
4794 * atimer.c (pending_atimers):
4795 * blockinput.h: Don't include "atimer.h"; no longer needed.
4796 (interrupt_input_pending): Remove. All uses removed.
4797 pending_signals now counts both atimers and ordinary interrupts.
4798 This is less racy than having three separate pending-signal flags.
4799 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4801 Rename from their upper-case counterparts BLOCK_INPUT,
4802 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4803 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4804 This makes it easier to access volatile variables more accurately.
4805 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4806 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4807 that's more reliable if the code is buggy and sets
4808 interrupt_input_blocked to a negative value. All uses changed.
4809 * atimer.c (deliver_alarm_signal):
4810 Remove. No need to deliver this to the parent; any thread can
4811 handle this signal now. All uses replaced by underlying handler.
4812 * atimer.c (turn_on_atimers):
4813 * dispnew.c (handle_window_change_signal):
4814 * emacs.c (handle_danger_signal):
4815 * keyboard.c (kbd_buffer_get_event):
4816 Don't reestablish signal handler; not needed with sigaction.
4817 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4819 Rework to avoid unnecessary accesses to volatile variables.
4820 (UNBLOCK_INPUT_TO): Now a function.
4821 (totally_unblock_input, unblock_input): New decls.
4822 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4823 (init_data): Remove. Necessary stuff now done in init_signal.
4824 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4825 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4826 (fatal_error_code): Remove; no longer needed.
4827 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4828 it doesn't always backtrace. All uses changed. No need to reset
4829 signal to default, since sigaction and/or die does that for us now.
4830 Use emacs_raise (FOO), not kill (getpid (), FOO).
4831 (main): Check more-accurately whether we're dumping.
4832 Move fatal-error setup to sysdep.c
4833 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4834 * gtkutil.c (xg_get_file_name, xg_get_font):
4835 Remove no-longer-needed signal-mask manipulation.
4836 * keyboard.c, process.c (POLL_FOR_INPUT):
4837 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4838 * keyboard.c (read_avail_input): Remove.
4839 All uses replaced by gobble_input.
4840 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4841 (kbd_buffer_store_event_hold, gobble_input):
4842 (record_asynch_buffer_change) [USABLE_SIGIO]:
4843 (store_user_signal_events):
4844 No need to mess with signal mask.
4845 (gobble_input): If blocking input and there are terminals, simply
4846 set pending_signals to 1 and return. All hooks changed to not
4847 worry about whether input is blocked.
4848 (process_pending_signals): Clear pending_signals before processing
4849 them, in case a signal comes in while we're processing.
4850 By convention callers now test pending_signals before calling us.
4851 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4852 New functions, to support changes to blockinput.h.
4853 (handle_input_available_signal): Now extern.
4854 (reinvoke_input_signal): Remove. All uses replaced by
4856 (quit_count): Now volatile, since a signal handler uses it.
4857 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4858 All callers changed. Block SIGINT only if not already blocked.
4859 Clear sigmask reliably, even if Fsignal returns, which it can.
4860 Omit unnecessary accesses to volatile var.
4861 (quit_throw_to_read_char): No need to restore sigmask.
4862 * keyboard.c (gobble_input, handle_user_signal):
4863 * process.c (wait_reading_process_output):
4864 Call signal-handling code rather than killing ourselves.
4865 * lisp.h: Include <float.h>, for...
4866 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4867 (pending_signals): Now volatile.
4868 (syms_of_data): Now const if IEEE floating point.
4869 (handle_input_available_signal) [USABLE_SIGIO]:
4870 (terminate_due_to_signal, record_child_status_change): New decls.
4871 * process.c (create_process): Avoid disaster if memory is exhausted
4872 while we're processing a vfork, by tightening the critical section
4874 (send_process_frame, process_sent_to, handle_pipe_signal)
4875 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4877 (send_process): No need for setjmp/longjmp any more, since the
4878 SIGPIPE stuff is now gone. Instead, report an error if errno
4880 (record_child_status_change): Now extern. PID and W are now args.
4881 Return void, not bool. All callers changed.
4882 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4883 Remove. All uses removed. This bug should be fixed now in a
4885 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4886 and record the child status change directly. This avoids the
4887 need to futz with the signal mask.
4888 (process_fatal_action): Move here from emacs.c.
4889 (emacs_sigaction_flags): New function, containing
4890 much of what used to be in emacs_sigaction_init.
4891 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4892 caught by emacs, to make races less likely.
4893 (deliver_process_signal): Rename from handle_on_main_thread.
4895 (BACKTRACE_LIMIT_MAX): Now at top level.
4896 (thread_backtrace_buffer, threadback_backtrace_pointers):
4898 (deliver_thread_signal, deliver_fatal_thread_signal):
4899 New functions, for more-accurate delivery of thread-specific signals.
4900 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4901 (deliver_arith_signal): Handle in this thread, not
4902 in the main thread, since it's triggered by this thread.
4903 (maybe_fatal_sig): New function.
4904 (init_signals): New arg DUMPING so that we can be more accurate
4905 about whether we're dumping. Caller changed.
4906 Treat thread-specific signals differently from process-general signals.
4907 Block all signals while handling fatal error; that's safer.
4908 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4910 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4911 Ignore SIGPIPE unless batch.
4912 (emacs_backtrace): Output backtrace for the appropriate thread,
4913 which is not necessarily the main thread.
4914 * syssignal.h: Include <stdbool.h>.
4915 (emacs_raise): New macro.
4916 * xterm.c (x_connection_signal): Remove; no longer needed
4917 now that we use sigaction.
4918 (x_connection_closed): No need to mess with sigmask now.
4919 (x_initialize): No need to reset SIGPIPE handler here, since
4920 init_signals does this for us now.
4922 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4924 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4925 background rect may be larger (Bug#12245).
4927 2012-09-23 Chong Yidong <cyd@gnu.org>
4929 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4931 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4933 * .gdbinit: Just stop at fatal_error_backtrace.
4934 See Stefan Monnier's request in
4935 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4936 Remove no-longer-used query of system type.
4938 2012-09-22 Chong Yidong <cyd@gnu.org>
4940 * search.c (Freplace_match): Doc fix (Bug#12325).
4942 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4944 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4945 (Fline_end_position): Doc fix.
4947 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4949 2012-09-22 Chong Yidong <cyd@gnu.org>
4951 * dispextern.h (struct image_type): Add new slot, storing a type
4952 initialization function.
4954 * image.c (define_image_type): Call the image initializer function
4955 if it is defined. Arguments and return value changed.
4956 (valid_image_p, make_image): Callers changed.
4957 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4958 (gif_type, imagemagick_type, svg_type, gs_type):
4959 Add initialization functions.
4960 (Finit_image_library): Call lookup_image_type.
4961 (CHECK_LIB_AVAILABLE): Macro deleted.
4962 (lookup_image_type): Call define_image_type here, rather than via
4963 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4964 (syms_of_image): Move define_image_type calls for xbm_type and
4965 pbm_type to lookup_image_type.
4967 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4969 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4970 'idle_timers' from here ...
4971 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4972 lists, to avoid infloops when the timer does something stupid,
4973 like reinvoke itself with the same or smaller time-out.
4976 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4978 * window.c (Fsplit_window_internal): Handle only Qt value of
4979 Vwindow_combination_limit separately.
4980 (Qtemp_buffer_resize): New symbol.
4981 (Vwindow_combination_limit): New default value.
4984 2012-09-22 Eli Zaretskii <eliz@gnu.org>

4987 the new overlay string. (Bug#10159)
4989 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4991 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4992 or that fprintf is async-signal-safe. POSIX doesn't require
4995 2012-09-22 Chong Yidong <cyd@gnu.org>
4997 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5000 2012-09-22 Kenichi Handa <handa@gnu.org>
5002 * composite.c (composition_reseat_it): Handle the case that a
5003 grapheme cluster is not covered by a single font (Bug#12352).
5005 2012-09-21 Chong Yidong <cyd@gnu.org>
5007 * image.c (define_image_type): Avoid adding duplicate types to
5008 image_types (Bug#12463). Suggested by Jörg Walter.
5010 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5012 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5013 (print_load_command_name): Add case LC_DATA_IN_CODE.
5014 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

5018 * eval.c (Frun_hook_with_args_until_success)
5019 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5021 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5023 * fileio.c (Ffile_selinux_context): Only call freecon when
5024 lgetfilecon succeeded.
5025 (Fset_file_selinux_context): Likewise. (Bug#12444)
5027 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5029 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5030 reordering, locate the cursor by calling set_cursor_from_row; if
5031 that fails, clear the desired glyph matrix before returning a
5032 failure indication to the caller. Fixes leaving garbled display
5033 when fast scrolling with a down-key. (Bug#12403)
5034 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5035 scrolling through multibyte text.
5037 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5039 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5040 calling mark_vectorlike since that's the one that marks the window.
5041 (mark_discard_killed_buffers): Mark the final cdr.
5042 * window.h (struct window): Move prev/next_buffers to the
5043 non-standard fields.
5044 * window.c (make_window): Initialize prev/next_buffers manually.
5046 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5048 Omit unused arg EXPECTED from socket hooks.
5049 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5050 * nsterm.m (ns_term_init):
5051 * termhooks.h (struct terminal.read_socket_hook):
5052 * w32inevt.c (w32_console_read_socket):
5053 * w32term.c (w32_read_socket):
5054 * xterm.c (XTread_socket):
5055 Omit unused arg EXPECTED. All callers changed.
5056 (store_user_signal_events): Return void, not int, since callers no
5057 longer care about the return value. All uses changed.
5059 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5061 * w32gui.h (XParseGeometry): Do not declare.
5063 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5065 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5066 Ignore 'expected'. See Eli Zaretskii in
5067 <http://bugs.gnu.org/12471#8> (last line).
5069 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5070 (XParseGeometry): Now static. Substitute extremal values for
5071 values that are out of range.
5073 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5075 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5077 * nsfns.m (XParseGeometry): Remove.
5078 (Fx_create_frame): Call x_set_offset to correctly interpret
5079 top_pos in geometry.
5081 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5082 (Fx_parse_geometry): If there is a space in string, call
5083 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5085 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5087 * search.c (scan_buffer): Use character positions in calls to
5088 region_cache_forward and region_cache_backward, not byte
5089 positions. (Bug#12196)
5091 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5092 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5094 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5095 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5096 emacs_blocked_malloc, now deleted.
5098 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5100 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5101 The workaround was for improving performance on Solaris 2.4, but
5102 is getting in the way now. Emacs will still work if someone is
5103 still running Solaris 2.4 in a museum somewhere; Sun dropped
5104 support for Solaris 2.4 in 2003.
5105 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5106 * process.c (create_process) [HAVE_WORKING_VFORK]:
5107 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5108 since Emacs no longer uses vfork on that platform.
5110 2012-09-17 Glenn Morris <rgm@gnu.org>
5112 * emacs.c: Use COPYRIGHT.
5114 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5116 Remove configure's --without-sync-input option (Bug#12450).
5117 When auditing signal-handling in preparation for cleaning it up,
5118 I found that SYNC_INPUT has race conditions and would be a real
5119 pain to fix. Since it's an undocumented and deprecated
5120 configure-time option, now seems like a good time to remove it.
5121 Also see <http://bugs.gnu.org/11080#16>.
5122 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5123 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5124 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5125 (malloc_hysteresis):
5126 (check_depth) [XMALLOC_OVERRUN_CHECK]:

5130 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5131 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5132 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5133 Remove. All uses removed.
5134 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5135 implementation, one that depends on whether the new macro
5136 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5138 * atimer.c (run_timers, handle_alarm_signal):
5139 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5140 (handle_async_input, process_pending_signals)
5141 (handle_input_available_signal, init_keyboard):
5142 * nsterm.m (ns_read_socket):
5143 * process.c (wait_reading_process_output):
5144 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5145 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5147 * xterm.c (XTread_socket):
5149 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5150 * eval.c (handling_signal): Remove. All uses removed.
5151 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5152 All uses replaced with the SYNC_INPUT version.
5153 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5155 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5158 * font.c (Ffont_shape_gstring): Remove unused local.
5160 2012-09-16 Glenn Morris <rgm@gnu.org>
5162 * Makefile.in (clean): No longer run nextstep's clean.
5164 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5166 (ns-app): Move here from ns.mk, and simplify.
5167 (clean): Simplify nextstep entry.
5168 * ns.mk: Remove file.
5170 2012-09-17 Kenichi Handa <handa@gnu.org>
5172 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5173 not covert the last few charactes.
5175 2012-09-16 Kenichi Handa <handa@gnu.org>
5177 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5178 here, but just check the validity of glyphs in the glyph-string.
5180 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5182 * window.c (Fwindow_parameter, Fset_window_parameter):
5183 Accept any window as argument (Bug#12452).
5185 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5187 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5188 to ns_term_init to avoid memory leak.
5190 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5191 explicit retain/release.
5192 (ns_term_init): Only allow one display. Initialize outerpool and
5195 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5197 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5198 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5199 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5200 the Microsoft problem in a different way, by altering ../nt/config.nt.
5202 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5217 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5218 by lisp.h. This completes removal of setjmp.h inclusion
5219 erroneously announced in the previous commit. (Bug#12446)
5221 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5224 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5225 not defined as a macro. The latter happens on MS-Windows.
5228 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5230 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5231 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5232 Some instances of '#include <setjmp.h>' removed, if the
5233 only reason for the instance was because "lisp.h" was included.
5234 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5235 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5236 and _longjmp with the new symbols. Emacs already uses _setjmp if
5237 available, so this change affects only POSIXish hosts that have
5238 sigsetjmp but not _setjmp, such as some versions of Solaris and
5239 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5240 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5241 (png_load_body) [HAVE_PNG]:
5242 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5243 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5244 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5245 since PNG requires jmp_buf. This is the only exception to the
5246 general rule that we now use sys_setjmp and sys_longjmp.
5247 This exception is OK since this code does not change the signal
5248 mask or longjmp out of a signal handler.
5250 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5252 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5253 Include "syssignal.h", for 'main_thread'.
5255 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5257 Avoid out-of-range marker position (Bug#12426).
5258 * insdel.c (replace_range, replace_range_2):
5259 Adjust markers before overlays, as suggested by comments.
5260 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5261 Remove redundant check before calling offset_intervals.
5263 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5265 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5266 current buffer (Bug#12387).
5268 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5270 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5272 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5274 Use a more backwards-compatible timer format (Bug#12430).
5275 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5276 vector element, not from the 4th, since PSECS is now at the end.
5277 (Fcurrent_idle_time): Doc fix.
5279 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5281 Function to mark objects and remove killed buffers at once.
5282 * alloc.c (discard_killed_buffers): Rename to ...
5283 (mark_discard_killed buffers) ... new name. Add marking
5284 of remaining objects. Fix comment. Adjust users.
5285 (mark_object): Do not touch frame buffer lists here.
5286 * frame.c (delete_frame): Reset frame buffer lists here.
5288 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5290 Better workaround for GNOME bug when --enable-gcc-warnings.
5291 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5292 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5293 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5295 Simplify SIGIO usage (Bug#12408).
5296 The code that dealt with SIGIO was crufty and confusing, e.g., it
5297 played tricks like "#undef SIGIO" but these tricks were not used
5298 consistently. Simplify mostly by not #undeffing standard symbols,
5299 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5300 or not as we please) rather than "defined SIGIO" (standard symbol
5301 that we probably shouldn't #undef).
5302 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5303 Modules that need it can include it.
5304 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5305 * dispextern.h (ignore_sigio): New decl.
5306 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5307 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5308 * emacs.c (shut_down_emacs):
5309 * keyboard.c (kbd_buffer_store_event_hold):
5310 Use ignore_sigio rather than invoking 'signal' directly.
5311 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5313 (FIONREAD, SIGIO): Do not #undef.
5314 (tty_read_avail_input): Use #error rather than a syntax error.
5315 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5316 for I_PIPE, used by SETUP_SLAVE_PTY.
5317 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5318 * sysdep.c (croak): Remove; no longer needed. This bit of
5319 temporary code, with Fred N. Fish's comment that it's temporary,
5320 has been in Emacs since at least 1992!
5321 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5322 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5323 * syssignal.h (croak): Remove decl.
5324 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5325 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5326 now that we're termios-only.
5327 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5328 * term.c (dissociate_if_controlling_tty): Use #error rather than
5331 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5332 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5333 to work around GNOME bug 683906.
5334 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5335 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5336 This works around GCC bug 54561.
5338 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5340 More fixes for 'volatile' and setjmp/longjmp.
5341 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5342 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5343 (png_load_body) [HAVE_PNG]:
5344 (jpeg_load_body) [HAVE_JPEG]:
5345 New function, with most of the old parent function's body.
5346 (png_load) [HAVE_PNG]:
5347 (jpeg_load) [HAVE_JPEG]:
5348 Invoke the new function, to avoid longjmp munging our locals.
5349 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5350 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5351 longjmp is passed 2, as the C standard doesn't guarantee this.
5352 Instead, store the failure code into mgr->failure_code.
5354 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5356 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5357 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5358 (syms_of_keyboard): Remove support for unread-command-char.
5360 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5362 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5363 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5364 violation. (Bug#12426)
5366 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5368 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5370 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5372 * eval.c: Add `inhibit-debugger'.
5373 (Qinhibit_debugger): New symbol.
5374 (call_debugger): Bind it instead of Qdebug_on_error.
5375 (maybe_call_debugger): Test Vinhibit_debugger.
5376 (syms_of_eval): Define inhibit-debugger.
5377 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5378 (syms_of_xdisp): Remove inhibit-debug-on-message.
5380 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5382 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5383 If a nonvolatile local variable is written before a _longjmp to
5384 the frame containing the variable, and is read after the _longjmp,
5385 the value read is indeterminate. Some local variables of type
5386 'struct handler' and 'struct catchtag' are used in this way, so
5387 mark each of their slots as volatile if the slot can be set before
5388 _longjmp and read afterwards.
5389 * lisp.h (struct handler): var and chosen_clause are now volatile.
5390 (struct catchtag): val, next, and pdlcount are now volatile.
5392 * bidi.c (bidi_push_it, bidi_pop_it):
5393 * fns.c (copy_hash_table):
5394 * image.c (define_image_type):
5395 * keyboard.c (kbd_buffer_store_event_hold):
5396 * process.c (Fprocess_send_eof):
5397 * xfaces.c (x_create_gc) [HAVE_NS]:
5398 * xgselect.c (xg_select):
5399 Prefer assignment to memcpy when either will do.
5401 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5402 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5403 time an item is removed. No need to mark this function 'inline';
5404 the compiler knows better than we do.
5406 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5408 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5409 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5410 to change_frame_size (Bug#12388).
5411 (windowDidResize:): Pass YES to updateFrameSize.
5413 * nsterm.h: Add delay parameter to updateFrameSize.
5415 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5417 Discard killed buffers from deleted window and frame objects.
5418 This reduces an amount of references to killed buffers and
5419 helps GC to reclaim them faster.
5420 * alloc.c (discard_killed_buffers): New function.
5421 (mark_object): Use it for deleted windows and frames.
5422 (mark_object): If symbol's value is set up for a killed buffer
5423 or deleted frame, restore its global binding.
5424 * data.c (swap_in_global_binding): Add GC notice.
5425 (swap_in_symval_forwarding): Use convenient set_blv_where.
5426 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5427 * window.h: ... to here.
5429 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5431 Convenient macro to check whether the buffer is live.
5432 * buffer.h (BUFFER_LIVE_P): New macro.
5433 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5434 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5436 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5438 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5439 composition cases (Bug#12364).
5441 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5442 overhang of succeeding glyphs overlapping box cursor.
5444 * w32term.c (x_draw_glyph_string): Likewise.
5446 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5448 Simplify, document, and port floating-point (Bug#12381).
5449 The porting part of this patch fixes bugs on non-IEEE platforms
5450 with frexp, ldexp, logb.
5451 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5453 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5454 support, by removing commented-out code and briefly listing the
5455 C89 functions excluded. The commented-out stuff was confusing
5456 maintenance, e.g., we thought we needed cbrt but it was commented out.
5457 (logb): Remove decl; no longer needed.
5458 (isfinite): New macro, if not already supplied.
5459 (isnan): Don't replace any existing macro.
5460 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5461 are present on all C89 platforms.
5462 (Ffrexp): Do not special-case zero, as frexp does the right thing
5464 (Flogb): Do not use logb, as it doesn't have the desired meaning
5465 on hosts that use non-base-2 floating point. Instead, stick with
5466 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5467 frexp, to avoid getting an unspecified result.
5469 * xdisp.c (Qinhibit_debug_on_message): Now static.
5471 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5473 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5474 NSBezierPath (Bug#12131).
5476 2012-09-10 Chong Yidong <cyd@gnu.org>
5478 * fns.c (Fdelq, Fdelete): Doc fix.
5480 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5482 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5483 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5485 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5487 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5488 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5491 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5493 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5494 left fringe if the window has a left margin. This avoids leaving
5495 traces of the cursor because its leftmost pixel is not drawn over.
5497 * dispnew.c (update_window_line): When the left margin area of a
5498 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5499 that screen line. (Bug#12277)
5501 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5503 Assume C89 or later for math functions (Bug#12381).
5504 This simplifies the code, and makes it a bit smaller and faster,
5505 and (most important) makes it easier to clean up signal handling
5506 since we can stop worring about floating-point exceptions in
5507 library code. That was a problem before C89, but the problem
5508 went away many years ago on all practical Emacs targets.
5509 * data.c, image.c, lread.c, print.c:
5510 Don't include <math.h>; no longer needed.
5511 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5512 might be autoconfigured, as that never happens.
5514 * doprnt.c (DBL_MAX_10_EXP):
5515 * print.c (DBL_DIG):
5516 Remove. C89 or later always defines these.
5517 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5518 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5519 (arith_error, domain_error, domain_error2):
5520 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5521 no longer needed -- we simply return what C returns. All uses removed.
5522 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5524 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5525 Remove. All uses expanded, as these macros are no longer used
5526 more than once and are now more trouble than they're worth.
5527 (Ftan): Use tan, not sin / cos.
5528 (Flogb): Assume C89 frexp.
5529 (fmod_float): Assume C89 fmod.
5530 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5531 (init_floatfns): Remove. All uses removed.
5533 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5535 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5536 compositeToPoint for OSX < 10.6 (Bug#12390).
5538 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5540 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5541 This produces more-accurate results.
5543 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5545 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5546 changes (Bug#12088).
5548 2012-09-08 Chong Yidong <cyd@gnu.org>
5550 * syntax.c (Fstring_to_syntax): Doc fix.
5552 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5554 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5555 in the internal border.
5556 (x_set_window_size): Remove static variables and their usage.
5557 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5558 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5559 Remove fringe/internal border adjustment (Bug#11052).
5560 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5561 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5562 (ns_fix_rect_ibw): Remove.
5563 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5564 (ns_dumpglyphs_box_or_relief): Ditto.
5565 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5567 (ns_dumpglyphs_image): Ditto.
5568 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5570 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5571 their usage. Add fringe_extended_p and its use as in other terms.
5572 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5573 scroll bar was removed.
5574 (updateFrameSize): New function.
5575 (windowDidResize): Move code to updateFrameSize and call it.
5577 * nsterm.h (EmacsView): Add updateFrameSize.
5579 2012-09-07 Chong Yidong <cyd@gnu.org>
5581 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5583 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5585 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5587 More signal-handler cleanup (Bug#12327).
5588 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5589 Problem introduced when merging patches. Noted by Eli Zaretskii in
5590 <http://bugs.gnu.org/12327#67>.
5591 * floatfns.c: Comment fix.
5592 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5593 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5594 and anyway the declaration is harmless even if SIGDANGER is not defined.
5595 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5596 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5597 source files not surprisingly expected syssignal.h to define, or
5598 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5599 Include <sys/ioctl.h>, for FIONREAD.
5600 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5601 This eliminates a problem whereby other files mysteriously had
5602 to include "syssignal.h" before including "systty.h" if they
5603 wanted to use "#ifdef SIGIO".
5605 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5607 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5609 * w32.c (sigemptyset): Empty the set.
5610 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5612 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5614 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5616 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5617 (mark_object): Likewise for frame objects.
5619 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5621 * syssignal.h (handle_on_main_thread): Always declare,
5622 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5623 This ports to platforms without HAVE_PTHREAD.
5625 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5627 Signal-handler cleanup (Bug#12327).
5628 Emacs's signal handlers were written in the old 4.2BSD style with
5629 sigblock and sigmask and so forth, and this led to some
5630 inefficiencies and confusion. Rewrite these to use
5631 pthread_sigmask etc. without copying signal sets around. Also,
5632 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5633 'signal', and instead use functions that do not attempt to take
5634 over the system name space. This patch causes Emacs's text
5635 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5636 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5637 Do not include <signal.h> or "syssignal.h", as these
5638 modules do not use signals.
5639 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5640 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5641 Do not include <signal.h>, as "syssignal.h" does that for us now.
5642 * atimer.c (sigmask_atimers): New function.
5643 (block_atimers, unblock_atimers): New functions,
5644 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5646 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5647 no longer needed here.
5648 * emacs.c (main): Inspect existing signal handler with sigaction,
5649 so that there's no need to block and unblock SIGHUP.
5650 * sysdep.c (struct save_signal): New member 'action', replacing
5651 old member 'handler'.
5652 (save_signal_handlers, restore_signal_handlers):
5653 Use sigaction instead of 'signal' to save and restore.
5654 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5655 New function. All users of 'signal' modified to use set_sighandler
5656 if they're writeonly, and to use sys_signal if they're read+write.
5657 (emacs_sigaction_init, forwarded_signal): New functions.
5658 (sys_signal): Remove. All uses replaced by calls to sigaction
5659 and emacs_sigaction_init, or by direct calls to 'signal'.
5660 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5661 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5662 all uses replaced by pthread_sigmask etc. calls.
5663 * syssignal.h: Include <signal.h>.
5664 (emacs_sigaction_init, forwarded_signal): New decls.
5665 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5666 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5667 (sigmask, sys_sigmask): Remove; no longer needed.
5668 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5669 (sigblock, sigunblock, sigfree):
5670 (sigsetmask) [!defined sigsetmask]:
5671 Remove. All uses replaced by pthread_sigmask.
5672 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5673 no longer need to be replaced, and its typical old uses
5674 are now done via emacs_sigaction_init and sigaction.
5675 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5676 (sys_sigdel): Remove; unused.
5677 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5679 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5681 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5682 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5684 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5686 Explicitly mark buffer_defaults and buffer_local_symbols.
5687 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5688 mark_local_symbols here.
5689 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5690 since special buffers aren't marked here any more.
5691 (allocate_buffer): Chain new buffer with all_buffers here...
5692 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5694 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5695 (syms_of_buffer): Remove staticpro of the above.
5696 (init_buffer_once): Set names for buffer_defaults and
5697 buffer_local_symbols.
5699 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5701 Use bool for booleans in font-related modules.
5702 * font.c (font_intern_prop, font_style_to_value)
5703 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5704 (generate_otf_features, font_check_otf_features, font_check_otf)
5705 (font_match_p, font_list_entities, font_at):
5706 * fontset.c (fontset_id_valid_p, reorder_font_vector
5707 (fontset_find_font, Fset_fontset_font)
5708 (face_suitable_for_char_p) [0]:
5709 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5710 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5711 (m17n_flt_initialized, ftfont_shape_by_flt):
5712 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5713 * nsfont.m (nsfont_draw):
5714 * w32font.c (w32font_draw):
5715 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5716 Use bool for booleans.
5717 * font.h: Adjust to above API changes.
5718 (struct font, struct font_driver, struct font_driver_list):
5719 Use bool for booleans.
5720 (struct font): Remove useless member encoding_type.
5722 * fontset.c, xftfont.c: Omit unnecessary static decls.
5724 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5726 * alloc.c (mark_object): Revert window marking code
5727 since it's unsafe for the Fset_window_configuration.
5729 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5731 Fix race conditions with signal handlers and errno (Bug#12327).
5732 Be more systematic about preserving errno whenever a signal
5733 handler returns, even if it's not in the main thread. Do this by
5734 renaming signal handlers to distinguish between signal delivery
5735 and signal handling. All uses changed.
5736 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5737 * data.c (deliver_arith_signal): Rename from arith_error.
5738 * dispnew.c (deliver_window_change_signal): Rename from
5739 window_change_signal.
5740 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5741 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5742 * keyboard.c (deliver_input_available_signal): Rename from
5743 input_available_signal.
5744 (deliver_user_signal): Rename from handle_user_signal.
5745 (deliver_interrupt_signal): Rename from interrupt_signal.
5746 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5747 (deliver_child_signal): Rename from sigchld_handler.
5748 * atimer.c (handle_alarm_signal):
5749 * data.c (handle_arith_signal):
5750 * dispnew.c (handle_window_change_signal):
5751 * emacs.c (handle_fatal_signal, handle_danger_signal):
5752 * keyboard.c (handle_input_available_signal):
5753 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5754 * process.c (handle_pipe_signal, handle_child_signal):
5755 New functions, with the actual signal-handling code taken from the
5756 original respective signal handlers, sans the sporadic attempts to
5757 preserve errno, since that's now done by handle_on_main_thread.
5758 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5759 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5760 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5762 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5763 Move initialization of main_thread to sysdep.c's init_signals.
5764 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5765 our usage, and simplifies the mainline code.
5766 (record_child_status_change): New static function, as a helper
5767 for handle_child_signal, and with most of the old child handler's
5769 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5770 (handle_child_signal): Use the above.
5771 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5772 Moved here from emacs.c.
5773 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5774 code moved here from emacs.c's main function.
5775 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5776 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5777 This lets callers save and restore errno properly.
5779 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5781 Remove redundant or unused things here and there.
5782 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5783 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5784 * editfns.c (Fcompare_buffer_substrings): Likewise.
5785 * frame.h (struct terminal, struct font_driver_list):
5786 Remove redundant declarations.
5787 * window.h (Qleft, Qright): Likewise.
5789 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5791 Do not mark objects from deleted buffers, windows and frames.
5792 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5793 (mark_object): Likewise for windows and frames.
5795 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5797 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5798 buffer_defaults and buffer_local_symbols as valid objects.
5799 Return special value to denote them.
5801 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5803 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5804 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5805 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5806 (file_name_absolute_p, Fsubstitute_in_file_name):
5807 (check_executable, check_writable, Ffile_accessible_directory_p)
5808 (Fset_file_selinux_context, Fdefault_file_modes)
5809 (Finsert_file_contents, choose_write_coding_system)
5810 (Fwrite_region, build_annotations, a_write, e_write)
5812 * filelock.c (boot_time_initialized, get_boot_time)
5813 (get_boot_time_1, lock_file_1, within_one_second):
5814 * floatfns.c (in_float):
5815 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5816 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5817 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5818 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5819 * window.c (compare_window_configurations):
5820 Use bool for booleans.
5821 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5822 (Fdefault_file_modes): Now mode_t, not int, for modes.
5823 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5824 (internal_delete_file): Now returns void, not a (boolean) int,
5825 since nobody was looking at the return value.
5826 * lisp.h, window.h: Adjust to above API changes.
5828 * xdisp.c (set_message): Simplify and reindent last change.
5830 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5832 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5834 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5836 * eval.c (call_debugger): Make the function non-static so that we
5837 can call it from set_message.
5839 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5840 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5842 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5844 Give more-useful info on a fatal error (Bug#12328).
5845 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5846 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5847 of doing the work ourselves.
5848 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5849 do most of the work.
5850 (fatal_error_backtrace): New function, taken from the guts
5851 of the old fatal_error_signal, but with a new option to output
5853 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5854 info about the signal than just its number.
5855 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5856 * sysdep.c: Include <execinfo.h>
5857 (emacs_backtrace): New function, taken partly from the previous
5858 code of the 'die' function.
5859 (emacs_abort): Call fatal_error_backtrace rather than abort.
5861 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5863 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5864 eager (load-time) macro-expansion.
5865 * lisp.mk (lisp): Add macroexp.
5867 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5869 Simplify redefinition of 'abort' (Bug#12316).
5870 Do not try to redefine the 'abort' function. Instead, redo
5871 the code so that it calls 'emacs_abort' rather than 'abort'.
5872 This removes the need for the NO_ABORT configure-time macro
5873 and makes it easier to change the abort code to do a backtrace.
5874 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5875 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5876 Remove; sysdep.c's emacs_abort now takes its place.
5877 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5878 'abort' changed to use 'emacs_abort'.
5879 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5880 (abort) [!defined abort]: Rename to ...
5881 (emacs_abort): ... new name.
5882 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5883 the place of the old 'abort' in emacs.c.
5884 * w32.c, w32fns.c (abort): Do not #undef.
5885 * w32.c (emacs_abort): Rename from w32_abort.
5887 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5889 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5890 offsets[j].dv, since the y axis of the screen coordinates points
5891 down, while the y axis of the font definition coordinates points
5892 up. This fixes display of Arabic diacritics such as KASRA and
5893 KASRATAN. (Bug#11860)
5895 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5897 Be more systematic about _setjmp vs setjmp.
5898 * alloc.c (test_setjmp, mark_stack):
5899 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5900 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5901 (png_load, my_error_exit, jpeg_load):
5902 * process.c (send_process_trap, send_process):
5903 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5904 The underscored versions are up to 30x faster on some hosts.
5905 Formerly, the code used setjmp+longjmp sometimes and
5906 _setjmp+_longjmp at other times, with no particular reason to
5907 prefer setjmp+longjmp.
5909 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5911 Fix minor problem found by static checking.
5912 * buffer.c (Fdelete_all_overlays): Return nil.
5914 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5916 * buffer.c (Fdelete_all_overlays): New function.
5918 2012-09-03 Chong Yidong <cyd@gnu.org>
5920 * gtkutil.c: Add extern decl for Qxft.
5922 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5924 * emacs.c, eval.c: Use bool for boolean.
5925 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5926 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5927 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5928 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5929 (main, decode_env_path, Fdaemon_initialized):
5930 * eval.c (call_debugger, Finteractive_p, interactive_p):

5944 * msdos.c (fatal_error_in_progress): ... from here.
5945 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5947 (redisplay_internal, unwind_redisplay): Simply clear
5948 REDISPLAYING_P when unwinding, instead of saving its previous,
5949 always-false value and then restoring it.
5951 Clean up some extern decls.
5952 Mostly, this hoists extern decls out of .c files and into .h files.
5953 That way, we're more likely to catch errors if the interfaces change.

6039 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6040 more than one grapheme cluster passed to the shaper: compute the
6041 offset adjustment values separately for each cluster. (Bug#11860)
6043 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6044 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6045 about implicit conversions from integer to pointer.
6047 2012-09-01 Daniel Colascione <dancol@dancol.org>
6049 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

6103 window system declarations.
6105 * frame.h: Move common functions here: set_frame_menubar,
6106 x_set_window_size, x_sync, x_get_focus_frame,
6107 x_set_mouse_position, x_set_mouse_pixel_position,
6108 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6169 * lread.c (init_lread): For out-of-tree builds, only add the
6170 source directory's site-lisp dir to the load-path if it exists,
6171 consistent with in-tree builds. (Bug#12302)
6173 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6194 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6195 Add window_closed and button_values. Add void as return value for
6196 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6197 Add process_dialog as new member.

6380 (syms_of_data): Do not define 'interval'.
6381 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6382 * window.h (decode_valid_window):
6385 * character.c, charset.c, chartab.c: Use bool for booleans.
6386 * character.c (lisp_string_width, string_count_byte8)
6387 (string_escape_byte8):
6388 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6389 (load_charset_map_from_file, map_charset_chars)
6390 (Fdefine_charset_internal, define_charset_internal)
6391 (Fdeclare_equiv_charset, find_charsets_in_text)
6392 (Ffind_charset_region, char_charset, Fiso_charset):
6393 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6394 (sub_char_table_set, sub_char_table_set_range)
6395 (char_table_set_range, optimize_sub_char_table)
6396 (map_sub_char_table):
6397 Use bool for boolean.
6398 * character.c (str_to_unibyte): Omit last boolean argument; it was
6399 always 0. All callers changed.
6400 * character.h, charset.h: Adjust to match previous changes.
6401 * character.h (char_printable_p): Remove decl of nonexistent function.
6402 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6403 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6404 are all boolean, so make them single-bit bitfields.
6406 * lisp.h (ASET): Remove attempt to detect side effects.
6407 It was meant to be temporary and it often doesn't work,
6408 because when IDX has side effects the behavior of IDX==IDX
6409 is undefined. See Stefan Monnier in
6410 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6412 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6414 * lisp.h (functionp): New function (extracted from Ffunctionp).
6415 (FUNCTIONP): Use it.
6416 * eval.c (Ffunctionp): Use it.
6418 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6420 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6421 as that's faster and simpler than static storage. Don't bother
6422 with the g_main_context_query overhead if g_main_context_pending
6423 says no events are pending.
6424 (gfds, gfds_size): Remove these static vars.
6425 (xgselect_initialize): Remove; no longer needed.
6426 All uses and decls removed.
6428 * emacs.c (fatal_error_signal_hook): Remove.
6429 All uses removed. This leftover from old code was always 0.
6431 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6432 * casefiddle.c (casify_object, casify_region):
6433 * casetab.c (set_case_table):
6434 * category.c, category.h (word_boundary_p):
6435 * category.h (CHAR_HAS_CATEGORY):
6436 Use bool for booleans, instead of int.
6438 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6440 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6442 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6444 On assertion failure, print backtrace if available.
6445 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6446 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6447 * Makefile.in (LIB_EXECINFO): New macro.
6450 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6451 * bytecode.c (exec_byte_code):
6452 * callint.c (check_mark, Fcall_interactively):
6453 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6454 (getenv_internal, sync_process_alive, call_process_exited):
6455 * lisp.h (USE_SAFE_ALLOCA):
6456 Use bool for booleans, instead of int.
6457 * lisp.h, process.h: Adjust prototypes to match above changes.
6458 * callint.c (Fcall_interactively): Don't assume the mark's
6459 offset fits in 'int'.
6461 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6463 * buffer.c, buffer.h: Use bool for boolean.
6464 * buffer.c (reset_buffer_local_variables)
6465 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6466 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6467 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6468 (overlay_touches_p, overlay_strings, Foverlay_put)
6469 (report_overlay_modification, call_overlay_mod_hooks):
6470 (mmap_enlarge, mmap_set_vars):
6471 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6472 Use bool for booleans, instead of int.
6473 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6474 since the 1-or-0 return value is always ignored anyway.
6475 (mmap_initialized_p):
6476 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6477 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6479 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6481 * bidi.c: Use bool for boolean.
6482 This is a bit more readable, and makes the text segment of bidi.o
6483 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6484 Presumably it's faster too.
6485 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6487 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6488 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6489 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6490 (bidi_explicit_dir_char, bidi_level_of_next_char)
6491 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6492 Use bool for booleans, instead of int.
6493 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6494 (bidi_unshelve_cache): Adjust decls to match code.
6496 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6498 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6501 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6503 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6504 * atimer.h: Include <stdbool.h>.
6506 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6508 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6509 compile time tests instead of run time tests on systems that do
6511 (FRAME_MAC_P): Remove leftover from deleted code.
6512 * frame.c (syms_of_frame): Remove leftover from deleted code.
6514 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6516 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6518 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6520 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6521 Otherwise, the compiler complains about (A?B:C) where B is void
6522 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6523 (fontset_add): Return void, for FONTSET_ADD.
6525 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6527 * alloc.c: Use bool for booleans.
6528 (gc_in_progress, abort_on_gc)
6529 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6530 (dont_register_blocks) [GC_MALLOC_CHECK]:
6531 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6532 (check_string_bytes, make_specified_string, memory_full)
6533 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6534 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6535 (mark_stack, valid_pointer_p, make_pure_string)
6536 (Fgarbage_collect, survives_gc_p, gc_sweep):
6537 Use bool for booleans, instead of int.
6538 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6539 Remove unused local.
6540 * alloc.c (PURE_POINTER_P):
6541 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6542 * editfns.c (Fformat):
6543 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6545 * fns.c (sweep_weak_table):
6546 * lisp.h (suppress_checking, push_message, survives_gc_p)
6547 (make_pure_string, gc_in_progress, abort_on_gc):
6548 * lread.c (readchar, read1):
6549 * print.c (Fprin1_to_string):
6550 * xdisp.c (push_message):
6551 Use bool for booleans affected directly or indirectly by
6554 Make recently-introduced setters macros.
6555 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6556 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6557 (set_fontset_default, set_fontset_fallback): Rename from their
6558 upper-case counterparts, and make them functions rather than macros.
6559 This is more consistent with the other recently-introduced setters.
6560 These don't need to be inline, since they're local.
6562 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6564 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6565 the loop (Bug#12247).
6567 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6569 * lisp.h (vcopy): Use memcpy rather than our own loop.
6570 This fixes a performance regression introduced by the recent
6571 addition of vcopy. This means 'vcopy' will need to be modified
6572 for a copying collector, but that's OK. Also, tighten the
6573 checking in the assertion.
6575 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6577 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6578 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6579 non-base glyph for the width of the base character, according to
6580 what x_draw_composite_glyph_string_foreground expects.
6581 Generate WADJUST value according to composition_gstring_width's
6582 expectations, to produce correct width of the composed character.
6583 Reverse the sign of the DU offset produced by ScriptPlace.
6585 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6587 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6589 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6591 Avoid direct writes to contents member of struct Lisp_Vector.
6592 * lisp.h (vcopy): New function to copy data into vector.
6593 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6594 * fns.c (Ffillarray): Use ASET.
6595 * keyboard.c (timer_check_2): Use AREF and ASET.
6596 (append_tool_bar_item, Frecent_keys): Use vcopy.
6597 * lread.c (read_vector): Use ASET.
6598 * msdos.c (Frecent_doskeys): Use vcopy.
6599 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6600 (Finternal_merge_in_global_face): Use ASET and vcopy.
6601 * xfont.c (xfont_list_pattern): Likewise.
6603 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6605 * window.c (Fwindow_point): For the selected window always return
6606 the position of its buffer's point.
6607 (Fset_window_point): For the selected window always go in its
6608 buffer to the specified position.
6610 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6612 Setter macros for fontsets.
6613 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6614 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6615 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6618 2012-08-20 Glenn Morris <rgm@gnu.org>
6620 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6621 Don't assume that `ln -f' works.
6623 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6625 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6626 and later about non-assignments with no effect. See discussion at
6627 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6630 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6632 Inline setter functions for Lisp_Objects slots of struct specbinding.
6633 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6636 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6638 * window.c (select_window): Always make selected window's buffer
6641 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6643 Use AREF and ASET for docstrings of category tables.
6644 * category.h (CATEGORY_DOCSTRING): Use AREF.
6645 (SET_CATEGORY_DOCSTRING): Use ASET.
6646 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6648 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6650 Inline setter functions for hash table members.
6651 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6652 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6653 (set_hash_key_and_value, set_hash_index, set_hash_next)
6654 (set_hash_hash): New functions.
6655 * charset.c, fns.c: Adjust users.
6657 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6659 Inline getter and setter functions for per-buffer values.
6660 * buffer.h (per_buffer_default, set_per_buffer_default)
6661 (per_buffer_value, set_per_buffer_value): New functions.
6662 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6663 * buffer.c, data.c: Adjust users.
6665 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6667 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6669 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6671 Rely on <config.h> + <unistd.h> to declare 'environ',
6672 as gnulib does this if the system doesn't.
6673 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6674 Remove declaration. MS-Windows declares it on stdlib.h which is
6675 included by conf_post.h.
6676 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6677 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6678 * vm-limit.c: Include <unistd.h>, for 'environ'.
6680 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6681 (start_of_data): Remove decl; mem-limits.h provides it.
6683 * xdisp.c (handle_invisible_prop): Make it a bit faster
6684 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6686 2012-08-19 Chong Yidong <cyd@gnu.org>
6688 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6691 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6693 * .gdbinit: Use call instead of set when calling a function in the
6696 * data.c (set_internal): Don't use set_blv_found.
6697 (Fkill_local_variable): Likewise.
6699 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6701 * nsfont.m (ns_ascii_average_width): Ensure the string
6702 ascii_printable is initialized with a null-terminated character
6703 array. Otherwise, it can contain undesired extra characters.
6705 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6707 port new setting code to Sun C 5.8 2005/10/13
6708 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6709 Return void, not Lisp_Object. Otherwise, the compiler
6710 complains about (A?B:C) where B is void and C is Lisp_Object
6711 when compiling CHAR_TABLE_SET, due to the recent change to
6712 the API of sub_char_table_set_contents.
6714 2012-08-18 Chong Yidong <cyd@gnu.org>
6716 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6717 for the string case (Bug#3874).
6719 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6721 * buffer.h (BSET): Remove (Bug#12215).
6722 Replace all uses with calls to new setter functions.

6791 New setter functions.
6793 * termhooks.h (TSET): Remove (Bug#12215).
6794 Replace all uses with calls to new setter functions.
6795 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
6796 (TERMHOOKS_INLINE): New macro.
6797 (tset_charset_list, tset_selection_alist): New setter functions.
6798 * terminal.c (TERMHOOKS_INLINE):
6799 Define to EXTERN_INLINE, so that the corresponding functions
6800 are compiled into code.
6801 (tset_param_alist): New setter function.
6803 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
6805 * keyboard.h (KSET): Remove (Bug#12215).

7549 value of EMACSLOADPATH, as it is no longer needed.
7550 (check_windows_init_file): Now external, not static.

7601 * alloc.c (record_xmalloc): New function.
7602 * lisp.h (record_xmalloc): New decl.
7603 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7604 more like a function. This is because the pointer cast is not
7605 needed. All uses changed.
7606 * print.c (print_string, print_error_message): Avoid length recalc.
7608 Improve fix for macroexp crash with debugging (Bug#12118).
7609 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

7643 with addition of handling of symlinks and support for 'lstat'.
7644 If possible, get file's attributes and security information by
7645 handle, not by name. Produce S_IFLNK bit for symlinks, when
7646 called from 'lstat'.
7647 (stat, lstat): New functions, call 'stat_worker'.
7648 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7649 symlinks when the underlying filesystem supports them.
7651 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7653 Fix macroexp crash on Windows with debugging (Bug#12118).
7654 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7655 checking subscripts; problem introduced with the recent
7656 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7657 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7658 since it's used in non-static inline functions now.
7660 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

8149 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8151 Improve GDB symbol export (Bug#12036).
8152 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8153 arms of an 'if', not using conditional expressions; otherwise GDB
8154 complains about the types in the unevaluated arm when the argument
8155 is an integer literal.
8156 (xgetint): Simplify expression.
8157 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8158 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8159 Zaretskii in <http://bugs.gnu.org/12036#13>.
8160 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8161 needed now that we have gdb_make_enums_visible.
8162 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8163 (enum enum_USE_LSB_TAG):
8164 New enum types, packaging up enums that need to be exported to GDB.
8166 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8168 Utility function to make a list from specified amount of objects.

8182 * xdisp.c (syms_of_xdisp): Likewise.
8183 * xfns.c (syms_of_xfns): Likewise.
8185 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8187 Fast save_excursion_save and save_excursion_restore.
8188 * lisp.h (struct Lisp_Excursion): New data type.
8189 (PVEC_EXCURSION): New pseudovector type.
8190 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8191 to deal with it. Adjust comments.
8192 (init_marker, attach_marker): New prototype.
8193 (unchain_marker): Adjust prototype.
8194 * marker.c (attach_marker): Change to global.

8202 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8204 Fix export of symbols to GDB (Bug#12036).
8205 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8206 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8207 emacs.c, as this is a more-suitable home. Had this been done earlier
8208 the fix for 12036 would have avoided some of the problems noted in
8209 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8210 would have been more obvious.
8211 * emacs.c: Do not include <verify.h>; no longer needed.
8212 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8213 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8214 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8215 Remove; now done in lisp.h.
8216 * lisp.h (PUBLISH_TO_GDB): New macro.
8217 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8218 (DATA_SEG_BITS): Use it.
8219 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8220 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8221 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8222 not be usable in #if. This simplifies things.
8224 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8226 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8228 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8230 Simplify export of symbols to GDB (Bug#12036).
8231 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8232 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8233 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8234 Adjust to changes in lisp.h and emacs.c, by using
8235 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8236 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8237 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8238 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8239 instead of gdb_valbits.
8240 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8241 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8242 instead of gdb_array_mark_flag.
8243 (xboolvector): Get size from $->size, not $->header.size.
8244 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8245 (xreload, hook-run, hookpost-run): Remove.
8246 * emacs.c: Include <verify.h>.
8247 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8248 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8250 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8251 (gdb_USE_LSB_TAG): New enum constants.
8252 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8253 Also define these as enum constants, so they're visible to GDB.
8254 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8255 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8256 as constants, so they're visible to GDB.
8257 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8258 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8259 Now enum constants, not macros, so they're visible to GDB.
8260 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8261 more convenient now. All uses changed.
8262 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8263 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8265 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8272 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8273 add argument, tune behavior, and adjust all callers.
8275 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8277 Use typedef for EMACS_INT, EMACS_UINT.
8278 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8279 than macros. This simplifies debugging in the usual case, since
8280 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8281 and it allows expressions involving EMACS_INT casts.
8282 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8284 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8294 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8296 Adjust buffer text indirection counters at the end of Fkill_buffer.
8297 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8298 buffer is definitely dead. This should really fix an issue reported
8299 by Christoph Scholtes again. (Bug#12007).
8300 (init_buffer_once): Initialize indirection counters of
8301 buffer_defaults and buffer_local_symbols (for sanity and safety).
8303 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8305 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8306 and continuation glyphs on tooltip frames, leave them at zero.
8307 Avoids continued lines in tooltips. (Bug#11832)
8309 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8311 Simplify copy_overlay.

8334 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8336 Swap buffer text indirection counters in Fbuffer_swap_text.
8337 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8338 This avoids crash reported by Christoph Scholtes at
8339 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8341 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8343 * nsmenu.m (Popdown_data): New struct.

8348 and autorelease them. Also autorelease img and matrix (Bug#12005).
8349 (dealloc): Remove (Bug#12005).

8366 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8368 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8369 as it's limited by the amount of memory, not by INT_MAX.
8371 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8373 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8374 in special-event-map. See the discussion at

8434 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8435 Adjust users accordingly.
8436 * font.h (font_open_by_name): Adjust prototype.

8455 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8456 'for_each_per_buffer_object_at'.
8457 All uses changed. It's better to use upper-case for macros that
8458 cannot be implemented as functions, to give the reader a clue
8459 that they're special.
8461 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

8504 * intervals.c (merge_interval_right, merge_interval_left):
8505 Do not zero out this interval if it is absorbed by its children,
8506 as this interval's total length doesn't change in that case. See
8507 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8509 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8511 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8512 when invoking (make-bool-vector N t) and N is a positive

8515 Remove some struct layout assumptions in bool vectors.
8516 * alloc.c (bool_header_size): New constant.
8517 (header_size, word_size): Move earlier, as they're now used earlier.

8520 padding before the data member of a bool vector.
8521 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
8522 than doing the check by hand with an abort ().
8524 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8526 * eval.c (Fdefvar): Don't check constants since we only set the var if
8527 it's not yet defined anyway (bug#11904).
8529 * lisp.h (last_undo_boundary): Declare new var.
8530 * keyboard.c (command_loop_1): Set it.
8531 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8532 were auto-added by the command loop (bug#11774).
8534 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
8536 * w32font.c (Qsymbol): Remove local definition.

9035 Move CLASH_DETECTION to configure.
9037 * s/gnu.h: Remove file, which is now empty.
9039 * s/gnu.h, s/gnu-linux.h:
9040 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
9042 2012-07-11 John Wiegley <johnw@newartisans.com>
9044 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9045 function attribute, so we only use it if it exists in the
9048 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9050 Avoid call to strlen in fast_c_string_match_ignore_case.
9051 * search.c (fast_c_string_match_ignore_case): Change to use
9052 length argument. Adjust users accordingly.
9053 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
9055 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

9076 (font_open_by_name): Change to use length argument.
9077 Adjust users accordingly.
9078 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
9080 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
9081 Change to return ptrdiff_t.
9082 (xfont_list_pattern, xfont_match): Use length returned by

9094 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
9096 Remove "#define unix" that is no longer needed (Bug#11905).
9097 * s/aix4-2.h (unix): Remove; no longer needed.
9099 EMACS_TIME simplification (Bug#11875).
9100 This replaces macros (which typically do not work in GDB)
9101 with functions, typedefs and enums, making the code easier to debug.
9102 The functional style also makes code easier to read and maintain.
9103 * systime.h: Include <sys/time.h> on all hosts, not just if
9104 WINDOWSNT, since 'struct timeval' is needed in general.
9105 (EMACS_TIME): Now a typedef, not a macro.
9106 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9108 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9110 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9111 (EMACS_TIME_LE): Now functions, not macros.
9112 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9113 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9114 which are not functions. All uses rewritten to use:
9115 (make_emacs_time): New function.
9116 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9117 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9118 not functions. All uses rewritten to use the following, respectively:
9119 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9120 (add_emacs_time, sub_emacs_time): New functions.
9121 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9122 * fileio.c (Fcopy_file):
9123 * xterm.c (XTflash): Get the current time closer to when it's used.
9124 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9130 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
9131 * frame.c (Fmake_terminal_frame):
9132 * gtkutil.c (get_utf8_string):
9134 * nsmenu.m (ns_update_menubar):
9135 * regex.c (regerror):
9136 Prefer memcpy to strncpy and strncat when either will do.
9137 * fileio.c (Fsubstitute_in_file_name):
9138 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9139 (menu_separator_name_p):
9140 * nsmenu.m (ns_update_menubar):
9141 Prefer memcmp to strncmp when either will do.
9142 * nsterm.m: Include <ftoastr.h>.
9144 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9145 Prefer snprintf to strncpy.
9146 * nsterm.m (ns_term_init):
9147 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9148 * nsterm.m (ns_term_init):
9149 Avoid the need for strncpy, by using build_string or
9150 make_unibyte_string directly. Use dtoastr, not snprintf.
9151 * process.c (Fmake_network_process): Diagnose service names that
9152 are too long, rather than silently truncating them or creating
9153 non-null-terminated names.
9154 (Fnetwork_interface_info): Likewise, for interface names.
9155 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9156 Prefer sprintf to strncat.
9157 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9158 Prefer vsnprintf to vsprintf + strncpy.
9160 2012-07-10 Glenn Morris <rgm@gnu.org>
9162 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9163 Clarify fallback case.
9165 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9167 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9168 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9169 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9170 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9171 where argument type is known to be a Lisp_Cons.
9173 2012-07-10 Tom Tromey <tromey@redhat.com>
9175 * bytecode.c (BYTE_CODE_THREADED): New macro.
9176 (BYTE_CODES): New macro. Replaces all old byte-code defines.
9177 (enum byte_code_op): New type.

9181 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9183 Optimize pure C strings initialization.
9184 * lisp.h (make_pure_string): Fix prototype.
9185 (build_pure_c_string): New function, defined as static inline. This
9186 provides a better opportunity to optimize away calls to strlen when
9187 the function is called with compile-time constant argument.
9188 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9189 argument, adjust users accordingly. Use build_pure_c_string where
9191 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9192 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9193 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9195 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9197 Avoid calls to strlen in miscellaneous functions.
9198 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9199 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9200 * lread.c (openp): Likewise.
9202 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9204 Avoid calls to strlen in path processing functions.
9205 * fileio.c (file_name_as_directory): Add comment. Change to add
9206 srclen argument and return the length of result. Adjust users
9208 (directory_file_name): Fix comment. Change to add srclen argument,
9209 swap 1st and 2nd arguments to obey the common convention.
9210 Adjust users accordingly.
9211 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9213 2012-07-10 Glenn Morris <rgm@gnu.org>
9215 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9216 Move PENDING_OUTPUT_COUNT definition to configure.
9218 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9219 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9220 * s/gnu.h (DATA_START): Move definitions to configure.
9222 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9223 We include usg5-4-common.h, which defines them both.
9225 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9226 O_RDONLY already includes it).
9228 Stop ns builds setting the EMACSLOADPATH environment variable.
9229 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9230 Now it does not set EMACSLOADPATH, just returns the load-path string.
9231 * nsterm.h: Update accordingly.
9232 * lread.c [HAVE_NS]: Include nsterm.h.
9233 (init_lread) [HAVE_NS]: Use ns_load_path.
9234 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9236 2012-07-09 Glenn Morris <rgm@gnu.org>
9238 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9239 since the included bsd-common.h does so.
9241 Stop ns builds setting the EMACSPATH environment variable.
9242 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9243 (ns_init_paths): Do not set EMACSPATH.
9244 * nsterm.h (ns_exec_path): Add it.
9245 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9248 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9250 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9252 * process.c (wait_reading_process_output): 'waitchannels' was unset
9253 when read_kbd || !NILP (wait_for_cell); fix this.
9255 Add GCC-style 'const' attribute to functions that can use it.
9256 * character.h (char_resolve_modifier_mask):
9257 * keyboard.h (make_ctrl_char):
9258 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9259 (init_character_once, next_almost_prime, init_fns, init_image)
9260 (flush_pending_output, init_sound):
9261 * mem-limits.h (start_of_data):

9265 Declare the dummy function with ATTRIBUTE_CONST.
9266 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9267 Add decls with ATTRIBUTE_CONST.
9269 Minor improvements to make_formatted_string.
9270 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9271 where int is good enough, as vsprintf returns an int.
9272 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9274 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9276 Use make_formatted_string to avoid double length calculation.
9277 * lisp.h (make_formatted_string): New prototype.

9283 * frame.c (make_terminal_frame, set_term_frame_name)
9284 (x_report_frame_params): Likewise.
9285 * image.c (gs_load): Likewise.
9286 * minibuf.c (get_minibuffer): Likewise.

9301 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9303 Move marker debugging code under MARKER_DEBUG.
9304 * marker.c (MARKER_DEBUG): Move marker debugging code under
9305 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9306 for bootstrap with --enable-checking (~3x slowdown reported
9307 by Juanma Barranquero <lekktu@gmail.com>).
9308 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9310 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9312 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9313 See <http://bugs.gnu.org/11825#29>.
9315 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9317 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9318 has no font, use the frame's font. (Bug#11813)
9319 (display_line): Add commentary about displaying truncation glyphs
9321 (produce_special_glyphs): Move here from term.c.
9323 * term.c (produce_special_glyphs): Move to xdisp.c.
9325 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9328 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9330 * xdisp.c (display_line): Avoid warning about implicit declaration
9333 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9335 * lisp.h: Remove empty conditional.
9337 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9339 * lread.c (load_path_check): Now static.
9341 Fix some minor --with-ns problems found by static checking.
9342 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9343 (x_set_font) [!HAVE_X_WINDOWS]:
9344 * image.c (xpm_load_image) [HAVE_NS]:
9345 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9346 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9347 Remove unused local.
9348 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9349 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9350 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9351 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9352 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9353 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9354 Fix pointer signedness problem.
9355 * xfaces.c (FRAME_X_FONT_TABLE):
9356 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9358 2012-07-07 Glenn Morris <rgm@gnu.org>
9360 * lread.c (load_path_check): New function, split from init_lread.
9361 (init_lread): Reorganize. Motivation:
9362 If EMACSLOADPATH is set, check/warn about that rather than the
9363 defaults, which we are not going to use. Hence we can remove
9364 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9365 Don't warn if site-lisp directories are missing.
9366 If not installed, start from a blank load-path, since
9367 PATH_LOADSEARCH refers to the eventual installation directories.
9369 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9371 Support truncation and continuation glyphs on GUI frames, when
9372 fringes are disabled. (Bug#11832)
9373 * xdisp.c (init_iterator): Get dimensions of truncation and
9374 continuation glyphs even if on GUI frames.
9375 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9376 or both, are absent.
9377 (start_display, move_it_in_display_line_to): Handle the case of a
9378 GUI frame without a fringe to display continuation or truncation
9380 (insert_left_trunc_glyphs): Support GUI frames: make sure
9381 truncation glyphs overwrite enough glyphs from the current line to
9382 have sufficient space in pixels.
9383 (display_line): Support truncation and continuation glyphs on GUI
9384 frames. If some spare pixels are left on the line after inserting
9385 the truncation glyphs, fill that space with a stretch glyph of a
9386 suitably computed width.
9388 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9389 produce_glyphs, to support GUI sessions.
9391 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9393 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9395 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9397 Do not require float-time's arg to fit in time_t (Bug#11825).
9398 This works better on hosts where time_t is unsigned, and where
9399 float-time is applied to the (negative) difference between two times.
9400 * editfns.c (decode_time_components): Last arg is now double *,
9401 not int *, and means to store all the result as a double, without
9402 worrying about whether the seconds part fits in time_t.
9403 All callers changed.
9404 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9405 All callers changed.
9406 (Ffloat_time): Do not fail merely because the specified time falls
9407 outside of time_t range.
9409 2012-07-07 Glenn Morris <rgm@gnu.org>
9411 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9412 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

9415 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9417 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9418 Update dependencies.
9420 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9422 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9424 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9425 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9426 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9427 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9428 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9429 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9431 * xfont.c (compare_font_names): Redo to omit the need for casts.
9433 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9435 * xfns.c (Fx_change_window_property): Doc fix.
9436 * w32fns.c (Fx_change_window_property): Doc fix.
9438 * w32fns.c (Fx_window_property): Accept the same arguments as the
9439 X Windows version. Doc fix.
9440 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9442 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9443 Eli Zaretskii <eliz@gnu.org>
9445 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9446 Windows-specific code from nt/config.nt moved here.
9447 Obsolete settings removed.
9449 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9451 * process.c: Avoid unnecessary calls to gettime.
9452 (wait_reading_process_output): Don't get the time of day
9453 when gobbling data immediately and not waiting, as there's no need
9454 for it in that case. This removes a FIXME.
9456 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9458 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9459 is defined (Bug#11768).
9461 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9463 Fix marker debugging code.
9464 * marker.c (byte_char_debug_check): Do not perform the check
9465 if buffer is not multibyte.
9466 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9467 Call byte_char_debug_check with correct arguments.
9469 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9471 Compile marker debugging code only if ENABLE_CHECKING is defined.
9472 * marker.c (byte_char_debug_check, count_markers):
9473 Use only if ENABLE_CHECKING is defined.
9474 (byte_debug_flag): Remove.
9475 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9476 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

9480 Avoid code repetition in marker-related functions.
9481 * marker.c (attach_marker): New function.
9482 (Fset_marker, set_marker_restricted, set_marker_both)
9483 (set_marker_restricted_both): Use it.
9484 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9485 Consistently rename charno to charpos.
9486 (marker_position): Add eassert.
9487 (marker_byte_position): Convert to eassert.
9489 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9491 Simplify list operations in unchain_overlay and unchain_marker.
9492 * buffer.c (unchain_overlay): Simplify. Add comment.
9493 * marker.c (unchain_marker): Simplify. Fix comments.
9495 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9497 Introduce fast path for the widely used marker operation.
9498 * alloc.c (build_marker): New function.
9499 * lisp.h (build_marker): New prototype.
9500 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9501 * composite.c (autocmp_chars): Likewise.
9502 * editfns.c (buildmark): Remove.
9503 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9504 (save_restriction_save): Use build_marker.
9505 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9506 * window.c (save_window_save): Likewise.
9508 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9511 to avoid redundant calls to unchain_overlay.
9512 * buffer.c (drop_overlay): New function.
9513 (delete_all_overlays, Fdelete_overlay): Use it.
9514 * minibuf.c (get_minibuffer): Fix comment.
9516 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9518 Port to OpenBSD 5.1 amd64.
9519 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9520 This is needed for OpenBSD, and should be harmless on all BSD systems.
9521 Also, include <sys/sysctl.h>, as it should be available on all
9522 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9523 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9524 use p_pid member, not kp_proc.pid.
9526 2012-07-06 Glenn Morris <rgm@gnu.org>
9528 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9530 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9532 More xmalloc and related cleanup.
9533 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9540 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9541 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9543 Omit needless casts involving void * pointers and allocation.
9544 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9545 as the former is more robust if P's type is changed.
9546 Prefer xzalloc to xmalloc + memset 0.
9547 Simplify malloc-or-realloc to realloc.
9548 Don't worry about xmalloc returning a null pointer.
9549 Prefer xstrdup to xmalloc + strcpy.
9550 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9552 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9553 alloca of a constant.
9555 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9557 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9558 hscroll is larger than the line width. Fixes long and futile
9559 looping inside extend_face_to_end_of_line (on a TTY) producing
9560 glyphs that are not needed and thrown away.
9562 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9564 * marker.c (set_marker_restricted_both): Simplify by using
9567 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9569 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9571 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9573 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9574 not defined (Bug#11768).
9575 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9576 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9577 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9578 followed by gtk_box_set_homogeneous (Bug#11768).
9579 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9580 (update_theme_scrollbar_width, xg_create_scroll_bar):
9581 Use gtk_scrollbar_new (Bug#11768).
9582 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9583 (is_box_type): New function (Bug#11768).
9584 (xg_tool_item_stale_p): Call is_box_type.
9585 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9586 with default display (Bug#11768).

9590 * xdisp.c (window_hscroll_limited): New function.
9591 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9592 coordinates when window's hscroll is set to insanely large
9595 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9597 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9603 * lisp.h (xzalloc): New prototype. Omit needless casts.
9604 * alloc.c (xzalloc): New function. Omit needless casts.
9605 * charset.c: Omit needless casts. Convert all calls to

9656 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9658 * fileio.c (time_error_value): Check the right error number.
9659 Problem reported by Troels Nielsen in
9660 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9662 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9664 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9665 This should be fixed in a better way; see Eli Zaretskii in
9666 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9667 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9669 * fileio.c (time_error_value): Rename from special_mtime.
9670 The old name's problems were noted by Eli Zaretskii in
9671 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9673 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9674 This variable's comment says Emacs needs at least one GDB-visible
9675 symbol of type enum pvec_type, to work around GDB problems.
9676 The symbol's value doesn't matter.
9678 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9679 that causes compilation to fail on pre-C99 compilers.
9681 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9683 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9684 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9686 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9688 * buffer.c (init_buffer_once): Fix initialization of
9689 headers for buffer_defaults and buffer_local_symbols.
9690 Reported by Juanma Barranquero <lekktu@gmail.com>.
9692 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9694 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9695 * lisp.h (enum pvec_type): Use fewer bits.
9696 (PSEUDOVECTOR_SIZE_BITS): New constant.
9697 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9698 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9699 change in pvec_type.
9700 (PSEUDOVECTOR_TYPEP): New macro.
9701 (TYPED_PSEUDOVECTORP): Use it.
9702 * fns.c (internal_equal): Adapt code to extract pvectype.
9703 * emacs.c (gdb_pvec_type): Update type.
9704 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9705 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9706 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9707 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9708 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9709 abusing vector->header.next.nbytes.
9710 (live_vector_p): Use PVEC_TYPE.
9711 (mark_object): Adapt code to extract pvectype. Use switch.
9713 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9715 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9716 Tighten new eassert a bit.
9718 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9720 Fix compilation with --enable-gcc-warnings and -O1
9722 * doprnt.c (doprnt): Change type of tem to int, initialize
9723 to avoid compiler warning. Add eassert.
9724 * search.c (simple_search): Initialize match_byte to avoid
9725 compiler warning. Add eassert.
9727 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9729 Avoid weird behavior with large horizontal scrolls.
9730 Without this change, for example, large hscroll values would
9731 mess up Emacs's display on Fedora 15 x86, presumably due to
9732 overflows in int calculations in the display code.
9733 Also, if buffers had long lines, Emacs would freeze.
9734 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9735 (set_window_hscroll): New function, containing the old guts of
9736 Fset_window_hscroll. Return the clipped value.
9737 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9738 This avoids the need to check against PTRDIFF_MAX.
9740 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9742 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9744 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9746 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9748 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9749 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9750 since GCC 4.4.6 issues a bogus warning for them.
9752 Fix bugs in file timestamp newness comparisons.
9753 * fileio.c (Ffile_newer_than_file_p):
9754 * lread.c (Fload): Use full timestamp resolution of files,
9755 not just the 1-second resolution, so that files that are only
9756 slightly newer still count as newer.
9757 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9758 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9760 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9762 * fileio.c: Improve handling of file time marker. (Bug#11852)
9763 (special_mtime): New function.
9764 (Finsert_file_contents, Fverify_visited_file_modtime):
9765 Use it to set special mtime values consistently.
9767 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9769 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9770 marker for non-existing file. (Bug#11852)
9772 2012-07-03 Glenn Morris <rgm@gnu.org>
9774 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9775 and did not make it into globals.h).
9777 2012-07-03 Tom Tromey <tromey@redhat.com>
9779 * window.c (Fset_window_margins, Fset_window_fringes)
9780 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9781 * textprop.c (Fprevious_property_change): No longer static.
9782 * syntax.c (Fsyntax_table_p): No longer static.
9783 * process.c (Fget_process, Fprocess_datagram_address): No longer

9797 * dired.c (Ffile_attributes): No longer static.
9798 * composite.c (Fcomposition_get_gstring): No longer static.
9799 * callproc.c (Fgetenv_internal): No longer static.
9801 * ccl.h: Remove EXFUNs.
9802 * buffer.h: Remove EXFUNs.
9803 * dispextern.h: Remove EXFUNs.
9804 * intervals.h: Remove EXFUNs.
9805 * fontset.h: Remove EXFUN.
9806 * font.h: Remove EXFUNs.
9807 * dosfns.c (system_process_attributes): Remove EXFUN.
9808 * keymap.h: Remove EXFUNs.
9809 * lisp.h: Remove EXFUNs.
9810 * w32term.h: Remove EXFUNs.
9811 * window.h: Remove EXFUNs.
9812 * xsettings.h: Remove EXFUN.
9813 * xterm.h: Remove EXFUN.
9815 2012-07-03 Glenn Morris <rgm@gnu.org>
9817 * lisp.h (Frandom): Make it visible to C.
9818 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9819 buffer for invisible buffers. (Bug#1229)
9821 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9823 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9824 values which aren't power of 2.
9825 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9826 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9829 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9831 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9833 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9835 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9837 * alloc.c (allocate_vector_block): Remove redundant
9838 calls to mallopt if DOUG_LEA_MALLOC is defined.
9839 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9840 avoid calls to mallopt if zero_vector is returned.
9842 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9844 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9845 is enabled, avoid dereferencing NULL current_sblock if
9848 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9850 Cleanup basic buffer management.
9851 * buffer.h (struct buffer): Change layout to use generic vector
9852 marking code. Fix some comments. Change type of 'clip_changed'
9853 to bitfield. Remove unused #ifndef old.
9854 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9855 (GET_OVERLAYS_AT): Fix indentation.
9856 (for_each_per_buffer_object_at): New macro.
9857 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9858 (Fbuffer_local_variables): Use it.
9859 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9860 * alloc.c (allocate_buffer): Adjust to match new layout of
9861 struct buffer. Fix comment.
9862 (mark_overlay): New function.
9863 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9864 Lisp area of struct buffer.
9865 (mark_object): Use it. Adjust marking of misc objects
9866 and related comments.
9868 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9870 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9871 wrapper that is not needed because the wrapped code is a no-op (zero
9872 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9873 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9875 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9877 * alloc.c (mark_buffer): Simplify. Remove prototype.
9878 (mark_object): Add comment. Reorganize marking of vector-like
9879 objects. Use CHECK_LIVE for all vector-like objects except buffers
9880 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9881 Avoid redundant calls to mark_vectorlike for bool vectors.
9883 2012-06-30 Glenn Morris <rgm@gnu.org>
9885 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9887 * epaths.in (PATH_SITELOADSEARCH): New.
9888 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9889 This is rather than relying on --enable-locallisppath elements
9890 having "site-lisp" in their names. (Bug#10208#25, 11658)
9892 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9894 * w32proc.c (sys_select): Accept and ignore one more argument.
9896 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9898 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9899 (pselect) [!MS_DOS]: Redirect to sys_select.
9901 * sysdep.c: Don't include dos.h and dosfns.h.
9903 * process.c (sys_select):
9904 * msdos.c (sys_select): Accept one more argument and ignore it.
9906 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9907 adapt data types and code to that.
9910 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9911 which clashes with the gnulib function of the same name.
9913 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9915 * font.c (font_style_to_value, font_style_symbolic)
9916 (font_prop_validate_style): Add type checks for values in
9919 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9921 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9924 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9926 * xdisp.c (try_window_id): Undo last change.
9928 * w32.c (getwd): Adjust commentary about startup_dir.
9929 (init_environment): Always call sys_access, even in non-MSVC
9930 builds. Don't chdir to the directory of the Emacs executable.
9931 This undoes code from 1997 which was justified by the need to
9932 "avoid conflicts when removing and renaming directories". But its
9933 downside was that every relative file name was being interpreted
9934 relative to the directory of the Emacs executable, which can never
9935 be TRT. In particular, it broke sys_access when called with
9936 relative file names.
9937 (sys_access): Map GetLastError to errno.
9939 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9941 * window.h (struct window): Change type of 'fringes_outside_margins'
9942 to bitfield. Fix comment. Adjust users accordingly.
9943 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9945 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9948 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

10129 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10131 Use sprintf return value instead of invoking strlen on result.
10132 In the old days this wasn't portable, since some sprintf
10133 implementations returned char *. But they died out years ago and
10134 Emacs already assumes sprintf returns int.
10135 Similarly for float_to_string.
10136 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10144 Use sprintf or float_to_string result to avoid need to call strlen.
10145 * data.c (Fnumber_to_string):
10146 Use make_unibyte_string, since the string must be ASCII.
10147 * lisp.h, print.c (float_to_string): Now returns int length.
10148 * term.c (produce_glyphless_glyph):
10149 Use sprintf result rather than recomputing it.
10151 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10159 strcasecmp if available.

10180 * xfns.c (x_window): Remove redundant cast.
10182 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10184 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10185 `const char *' to `char *' to avoid compiler warning.
10187 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10189 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10190 instead of truncating it to 63 (admittedly a generous limit).
10192 * process.c: Fix spelling and caps in comments.

10250 * keyboard.c (kbd_buffer_get_event):
10251 * process.c (Faccept_process_output):
10252 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10253 This improves on the previous patch, which introduced a bug
10254 when time_t is unsigned and as wide as intmax_t.
10255 See <http://bugs.gnu.org/9000#51>.
10257 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10286 language ID in the event parameters.
10288 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10289 event.code, not the obscure "character set ID".

10322 Support higher-resolution time stamps (Bug#9000).
10323 The time stamps are only nanosecond-resolution at the C level,
10324 since that's the best that any real-world system supports now.
10325 But they are picosecond-resolution at the Lisp level, as that's
10326 easy, and leaves room for future OS improvements.
10328 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10331 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10332 Don't get current time unless it's needed.
10334 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10335 now provides it if it's absent.
10336 (start_atimer): Port to higher-res time stamps.
10337 Check for time stamp overflow. Don't get current time more
10338 often than is needed.
10340 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10341 Include systime.h, not time.h.

10344 * dired.c: Include stat-time.h.
10345 (Ffile-attributes): File times now have higher resolution.
10347 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10348 (struct image): Timestamp now has higher resolution.
10350 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10351 has at least microseconds now. All uses removed.
10352 (update_frame, update_single_window, update_window, update_frame_1)
10353 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10354 (duration_to_sec_usec): Remove; no longer needed.
10356 * editfns.c (time_overflow): Now extern.
10357 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10358 (float-time, Fformat_time_string, Fcurrent_time_string)

10362 (decode_time_components, lisp_seconds_argument): New functions.
10363 (make_time): Now static.
10364 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10365 Report an error if the time is invalid, rather than having the caller
10368 * fileio.c: Include <stat-time.h>
10369 (Fcopy_file): Copy higher-resolution time stamps.
10370 Prefer to set the time stamp via a file descriptor if that works.
10371 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10372 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10373 (Fvisited_file_modtime, Fset_visited_file_modtime):
10374 Support higher-resolution time stamps.
10376 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10378 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10380 * image.c (prepare_image_for_display, clear_image_cache)
10381 (lookup_image): Port to higer-resolution time stamps.
10383 * keyboard.c (start_polling, bind_polling_period):
10384 Check for time stamp overflow.
10385 (read_char, kbd_buffer_get_event, timer_start_idle)
10386 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10387 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10388 Port to higher-resolution time stamps. Do not assume time_t is signed.
10389 (decode_timer): New function. Timers are now vectors of length 9,
10390 not 8, to accommodate the picosecond component.
10391 (timer_check_2): Use it.
10393 * nsterm.m (select_timeout, timeval_subtract): Remove.
10394 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10395 as they're a bit more accurate and handle overflow better.
10396 (ns_select): Change prototype to be compatible with pselect.
10397 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10398 * nsterm.h (ns_select): Adjust prototype.
10400 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10401 us-resolution time stamps.
10402 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10404 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10406 * lisp.h (time_overflow): New decl.
10407 (wait_reading_process_output): First arg is now intmax_t, not int,
10408 to accommodate larger waits.
10410 * process.h (struct Lisp_Process.read_output_delay):
10411 Now counts nanoseconds, not microseconds.
10412 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10414 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10415 (wait_reading_process_output):
10416 Port to ns-resolution time stamps.
10417 (Faccept_process_output, wait_reading_process_output):
10418 Check for time stamp overflow. Do not assume time_t is signed.
10419 (select_wrapper): Remove; we now use pselect.
10420 (Fprocess_attributes): Now generates ns-resolution time stamps.
10422 * sysdep.c: Include utimens.h. Don't include utime.h
10423 or worry about struct utimbuf; gnulib does that for us now.
10424 (gettimeofday): Remove; gnulib provides a substitute.
10425 (make_timeval): New function.
10426 (set_file_times): Now sets ns-resolution time stamps.
10427 New arg FD; all uses changed.
10428 (time_from_jiffies, ltime_from_jiffies, get_up_time)

10430 Now returns ns-resolution time stamp. All uses changed.
10431 Check for time stamp overflow.

10434 provides a substitute now.
10436 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10437 since it guarantees struct timespec.
10438 (EMACS_TIME): Now struct timespec, so that we can support
10439 ns-resolution time stamps.
10440 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10441 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10442 (EMACS_USECS): Remove.
10443 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10444 so multiply the arg by 1000 before storing it.

10454 (make_timeval, make_lisp_time, decode_time_components): New decls.
10455 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10456 that it mishandled time_t overflow. You can't compare by subtracting!
10457 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10458 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10460 * term.c: Include <sys/time.h>.
10461 (timeval_to_Time): New function, for proper overflow wraparound.
10462 (term_mouse_position, term_mouse_click): Use it.

10465 in the undo buffer.
10466 (Fprimitive_undo): Use them when restoring time stamps.

10469 (w32_get_internal_run_time):
10470 Port to higher-resolution Emacs time stamps.
10471 (ltime): Now accepts single 64-bit integer, as that's more convenient
10474 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10476 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10477 for compatibility with pselect. Support ns-resolution time stamps.
10479 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10481 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10482 Check for time stamp overflow, and support ns-resolution time stamps.
10484 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10485 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10486 (timeval_subtract): Remove; no longer needed.
10487 (XTflash, XTring_bell, x_wait_for_event):
10488 Port to ns-resolution time stamps. Don't assume time_t is signed.

10497 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10498 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10499 staticidx goes up to 1597 out of 1600 = 0x640.)
10501 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10503 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10504 Otherwise, the umask might be mistakenly 0 while handling input signals.
10506 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

10524 frame's selected window and its terminal's top-frame.
10525 (unwind_format_mode_line): Restore them.
10526 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10528 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10529 since tty frames can be explicitly named.
10530 (prepare_menu_bars): Likewise.
10532 * term.c (Ftty_top_frame): New function.
10534 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10536 Port byte-code-meter to modern targets.
10537 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10538 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10539 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10540 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10547 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10549 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10550 gets killed during executing of this function (Bug#11665).
10551 Try to always return Qt when the buffer has been actually killed.
10552 (Vkill_buffer_query_functions): In doc-string say that functions
10553 run by this hook should not change the current buffer.
10555 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10557 Fix recently-introduced process.c problems found by static checking.

10577 * lisp.h (eassert): Assume C89 or later.
10578 This removes the need for CHECK.
10579 (CHECK): Remove. Its comments about always evaluating its
10580 argument were confusing, as 'eassert' typically does not evaluate
10583 * coding.c (produce_chars): Use ptrdiff_t, not int.
10585 * xterm.c (x_draw_underwave): Check for integer overflow.
10586 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10774 Use an inline function on all platforms when using the union type,

10862 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10863 would generate the diagnostic "Making \302\247 buffer-local while
10866 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10868 * dispnew.c (showing_window_margins_p): Undo last change, which
10869 was done due to an inadvertent commit.
10870 (adjust_frame_glyphs_for_frame_redisplay): Do call
10871 showing_window_margins_p.
10873 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
10875 * eval.c (Fmake_var_non_special): New primitive.

10879 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
10881 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
10882 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
10884 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10886 * alloc.c (allocate_vectorlike): Fix last change.
10888 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
10890 Block-based vector allocation of small vectors.
10891 * lisp.h (struct vectorlike_header): New field `nbytes',
10892 adjust comment accordingly.
10893 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10894 to denote vector blocks. Adjust users (live_vector_p,
10895 mark_maybe_pointer, valid_lisp_object_p) accordingly.
10896 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
10897 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
10898 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
10899 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
10900 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
10901 (roundup_size): New constant.

10906 (sweep_vectors): New functions.
10907 (allocate_vectorlike): Return `zero_vector' as the only vector of
10908 0 items. Allocate new vector from block if vector size is less than
10909 or equal to VBLOCK_BYTES_MAX.
10910 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
10911 (init_alloc_once): Add call to init_vectors.
10913 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
10915 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
10917 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10919 * doprnt.c (doprnt): Truncate multibyte char correctly.
10920 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10921 would mishandle a string argument "Xc" if X was a multibyte
10922 character of length 2: it would truncate after X's first byte
10923 rather than including all of X.
10925 2012-06-06 Chong Yidong <cyd@gnu.org>
10927 * buffer.c (word_wrap): Doc fix.
10929 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10941 binary via PaX flags if the paxctl utility is available.
10942 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10943 Restore PaX flags to their default. (Bug#11398)
10945 2012-06-03 Chong Yidong <cyd@gnu.org>
10947 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10948 buffer (Bug#11226).

10952 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
10953 (note_mode_line_or_margin_highlight): If there is no help echo,
10954 use mode-line-default-help-echo. Handle the case where the mouse
10955 position is past the end of the mode line string.
10957 * buffer.c (buffer_local_value_1): New function, split from
10958 Fbuffer_local_value; can return Qunbound.
10959 (Fbuffer_local_value): Use it.
10960 (Vmode_line_format): Docstring tweaks.
10962 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10964 * sysdep.c (system_process_attributes): Improve comment.
10966 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
10968 * keyboard.c: Export real-this-command to Elisp.
10969 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
10970 and DEFVAR it. Update all users.
10972 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10974 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10976 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10977 Convert pctcpu and pctmem to Lisp float properly.
10978 Let the compiler fold better, as 100.0/0x8000 is exact.
10980 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10982 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10985 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
10987 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
10989 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10991 For a 'struct window', replace some Lisp_Object fields to
10992 bitfields where appropriate, remove unused fields.
10993 * window.h (struct window): Remove unused 'last_mark_x' and
10994 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10995 change its type from Lisp_Object to bitfield.
10996 Change type of 'force_start', 'optional_new_start',
10997 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10998 fields from Lisp_Object to bitfield. Adjust users accordingly.
11000 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11002 Pacify gcc -Wdouble-precision when using Xaw.
11003 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11004 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11005 Use 'float' consistently, rather than 'float' in most places
11006 and 'double' in a couple of places.
11008 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11010 * xdisp.c (handle_stop): Detect whether we have overlay strings
11011 loaded by testing it->current.overlay_string_index to be
11012 non-negative, instead of checking whether n_overlay_strings is
11013 positive. (Bug#11587)
11015 2012-05-31 Chong Yidong <cyd@gnu.org>
11017 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11019 * doc.c (Fsubstitute_command_keys): Doc fix.
11021 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11023 * search.c (search_buffer): Remove calls to
11024 r_alloc_inhibit_buffer_relocation, as it is now called by
11025 maybe_unify_char, which was the cause of relocation of buffer text
11028 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11030 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11031 for the duration of call to load_charset, to avoid problems with
11032 callers of maybe_unify_char that access buffer text through C
11035 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11036 decrement the inhibition flag, instead of just setting or
11039 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11041 Remove obsolete '#define static' cruft.
11042 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11043 This #undef was "temporary" in 2000; it is no longer needed
11044 now that '#define static' has gone away.
11045 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11046 (gray_bitmap_bits): Remove; no longer needed.
11047 All uses replaced with definiens.
11048 * xterm.c: Include "bitmaps/gray.xbm".
11050 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11052 Clean up __executable_start, monstartup when --enable-profiling.
11053 The following changes affect the code only when profiling.
11054 * dispnew.c (__executable_start): Rename from safe_bcopy.
11055 Define only on platforms that need it.
11056 * emacs.c: Include <sys/gmon.h> when profiling.
11057 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11058 (__executable_start): Remove decl, since lisp.h does it now.
11059 (safe_bcopy): Remove decl; no longer has that name.
11060 (main): Coalesce #if into single bit of code, for simplicity.
11061 Cast pointers to uintptr_t, since standard libraries want integers
11063 * lisp.h (__executable_start): New decl.
11065 2012-05-31 Glenn Morris <rgm@gnu.org>
11067 * image.c (Fimagemagick_types): Doc fix.

11085 * lisp.h (Qdefun): Remove.
11086 * lread.c (read1): Tiny simplification.
11088 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11090 Do not create empty overlays with the evaporate property (Bug#9642).
11091 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11092 Bug#9642, but explicitly check that the buffer the overlay would
11093 be moved to is live and rearrange lines to make sure that errors
11094 will not put the overlay in an inconsistent state.
11095 (Fdelete_overlay): Cosmetics.
11097 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11099 * w32term.c (my_bring_window_to_top): New function.
11100 (x_raise_frame): Use handle returned by DeferWindowPos, which
11101 could be different from the original one.
11102 Call my_bring_window_to_top instead of my_set_foreground_window.
11105 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP

11111 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11113 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11114 This avoids undefined behavior that might cause the eassert
11115 to not catch an out-of-range value.
11117 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11119 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11120 Update dependencies.
11122 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11124 * bidi.c (bidi_mirror_char): Fix last change.
11126 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11131 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11133 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11134 Only r_alloc_inhibit_buffer_relocation needed to be added;
11135 the others were already declared.
11137 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11138 before checking whether it's out of range. Put the check inside
11140 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11142 2012-05-27 Ken Brown <kbrown@cornell.edu>
11144 * callproc.c (Fcall_process): Restore a line that was accidentally
11145 commented out in the 2011-02-13 change (bug#11547).
11147 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11149 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11150 defined on ralloc.c.
11152 * buffer.c [REL_ALLOC]: Remove prototypes of
11153 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11154 they are now on lisp.h.
11156 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11158 * search.c (search_buffer): Use it to inhibit relocation of buffer
11159 text while re_search_2 is doing its job, because re_search_2 is
11160 passed C pointers to buffer text. (Bug#11519)
11162 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11163 Update value to 24.
11165 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11166 state after an additional call to move_it_in_display_line_to, keep
11167 the values of it->max_ascent and it->max_descent found for the
11169 (pos_visible_p): Revert the comparison against bottom_y to what it
11170 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11173 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11175 Fix coding-related core dumps with gcc -ftrapv.
11176 The code was computing A - B, where A and B are pointers, and B is
11177 random garbage. This can lead to core dumps on platforms that
11178 have special pointer registers, and it also leads to core dumps on
11179 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11180 A - B only when B is initialized properly.
11181 * coding.c (coding_set_source, coding_set_destination): Return void.
11182 (coding_change_source, coding_change_destinations): New functions,
11183 with the old behaviors of coding_set_source and coding_set_destination.
11184 All callers that need an offset changed to use these new functions.
11186 2012-05-26 Glenn Morris <rgm@gnu.org>
11188 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11190 2012-05-26 Eli Zaretskii <eliz@gnu.org>

11193 * xdisp.c (draw_row_with_mouse_face):
11194 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11196 * w32console.c: Include window.h.
11197 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11199 (initialize_w32_display): Initialize mouse-highlight data.
11201 * w32inevt.c: Include termchar.h and window.h.
11202 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11203 moves, call note_mouse_highlight. If help_echo changed, call
11204 gen_help_event to produce help-echo message in the echo area.
11205 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11208 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11210 * lread.c (read1): Simplify slightly to avoid an overflow warning
11211 with GCC 4.7.0 on x86-64.
11213 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11215 * bidi.c (bidi_mirror_char): Revert last change: an int is
11216 definitely wide enough here.
11218 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11220 Fix integer width and related bugs (Bug#9874).

11227 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11228 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11230 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11231 (allocate_pseudovector):
11232 Use int, not EMACS_INT, where int is wide enough.
11233 (inhibit_garbage_collection, Fgarbage_collect):
11234 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11235 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11236 int might not be wide enough.
11237 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11238 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11239 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11240 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11241 (bidi_level_of_next_char, bidi_move_to_visually_next):
11242 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11243 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11244 (Fkill_buffer, Fset_buffer_major_mode)
11245 (advance_to_char_boundary, Fbuffer_swap_text)
11246 (Fset_buffer_multibyte, overlays_at, overlays_in)
11247 (overlay_touches_p, struct sortvec, record_overlay_string)
11248 (overlay_strings, recenter_overlay_lists)
11249 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11250 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

11252 (Foverlay_recenter, last_overlay_modification_hooks_used)
11253 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11254 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11255 (validate_region): Omit unnecessary test for b <= e,
11256 since that's guaranteed by the previous test.
11257 (adjust_overlays_for_delete): Avoid pos + length overflow.
11258 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11259 (report_overlay_modification):
11260 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11261 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11262 Omit pointer cast, which isn't needed anyway, and doesn't work
11263 after the EMACS_INT -> ptrdiff_t change.
11264 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11265 * buffer.h: Adjust decls to match defn changes elsewhere.
11266 (struct buffer_text, struct buffer):
11267 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11268 Use EMACS_INT, not int, where int might not be wide enough.
11269 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11270 not int, to avoid needless 32-bit limit on 64-bit hosts.
11271 (exec_byte_code): Use tighter memory-full test, one that checks
11272 for alloca overflow. Don't compute the address of the object just
11273 before an array, as that's not portable. Use EMACS_INT, not
11274 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11275 * callint.c (Fcall_interactively):
11276 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11277 * callproc.c (call_process_kill, Fcall_process):
11278 Don't assume pid_t fits into an Emacs fixnum.

11286 * casefiddle.c (casify_object, casify_region, operate_on_word)
11287 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11288 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11289 (casify_object): Avoid integer overflow when overallocating buffer.
11290 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11291 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11292 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11293 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11294 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11295 integers are now checked earlier. All uses replaced with XINT.
11297 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11298 For CCL_MapSingle, check that content and value are in int range.
11299 (ccl_driver, Fregister_code_conversion_map):
11300 Check that Vcode_version_map_vector is a vector.
11301 (resolve_symbol_ccl_program): Check that vector header is in range.
11302 Always copy the vector, so that we can check its contents reliably
11303 now rather than having to recheck each instruction as it's being
11304 executed. Check that vector words fit in 'int'.
11305 (ccl_get_compiled_code, Fregister_ccl_program)
11306 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11307 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

11309 contents are in range.
11310 (Fccl_execute_on_string): Check that status is in range.

11312 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

11320 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11333 Don't rely on undefined behavior with signed left shift overflow.
11334 Don't assume unsigned int fits into fixnum, or that fixnum fits
11335 into unsigned int. Don't require max_code to be a valid fixnum;
11336 that's not true for gb10830 4-byte on a 32-bit host. Allow
11337 invalid_code to be a cons, for the same reason. Require code_offset
11338 to be a character. Avoid int overflow if max_char is close
11340 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11341 this is intended anyway and avoids some undefined behavior.
11342 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11343 INDEX_TO_CODE_POINT, as that's what it expects.
11344 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11345 * charset.h (DECODE_CHAR): Return int, not unsigned;
11346 this is what was intended anyway, and it avoids undefined behavior.

11348 integer-overflow issues.
11349 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11350 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11351 where the argument is EMACS_INT, and this behavior is not intended.
11352 * chartab.c (Fmake_char_table, Fset_char_table_range)
11353 (uniprop_get_decoder, uniprop_get_encoder):
11354 Don't assume fixnum fits in int.
11355 * cmds.c (move_point): New function, that does the gist of

11963 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
11964 (handle_tool_bar_click):
11965 Use int, not unsigned, since we prefer signed and the signedness
11966 doesn't matter here.
11967 (get_next_display_element, next_element_from_display_vector):
11968 Use int, not EMACS_INT, when int is wide enough.
11969 (start_hourglass): Use duration_to_sec_usec to do proper
11970 overflow checking on durations.
11971 * xfaces.c (Fbitmap_spec_p):
11972 Check that fixnums are in proper range for system types.
11973 (compare_fonts_by_sort_order):
11974 Avoid mishandling comparisons due to subtraction overflow.
11975 (Fx_family_fonts, realize_basic_faces):
11976 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11978 Don't assume fixnum fits in int.
11979 Use SAFE_ALLOCA_LISP, not alloca.
11980 (merge_face_heights): Remove unnecessary cast to EMACS_INT.
11981 (Finternal_make_lisp_face): Don't allocate more than MAX_FACE_ID.
11982 (face_at_buffer_position, face_for_overlay_string)
11983 (face_at_string_position):
11984 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11985 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
11986 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
11988 Check that fixnums are in proper range for system types.
11989 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
11990 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
11991 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11992 (Fx_change_window_property): Don't assume fixnums fit in int.
11993 * xfont.c (xfont_chars_supported):
11994 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11995 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
11996 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
11997 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11998 * xml.c (parse_region):
11999 * xrdb.c (magic_file_p):
12000 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12001 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
12002 (x_get_local_selection, x_reply_selection_request)
12003 (x_handle_selection_request, wait_for_property_change):
12004 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12005 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12006 short is wide enough.
12007 (x_send_client_event): Don't assume fixnum fits in int.
12008 * xterm.c (x_x_to_emacs_modifiers):
12009 Don't assume EMACS_INT overflows nicely into int.
12010 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12011 may come from Lisp.
12012 (handle_one_xevent): NATNUMP can eval its arg twice.
12013 (x_connection_closed):
12014 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12015 * xterm.h: Adjust decls to match defn changes elsewhere.
12016 (struct scroll_bar): Use struct vectorlike_header
12017 rather than rolling our own approximation.
12018 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12020 2012-05-25 Glenn Morris <rgm@gnu.org>
12022 * lisp.mk (lisp): Update for more files being compiled now.
12024 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12026 * lread.c: Remove `read_pure' which makes no difference.
12027 (read_pure): Remove var.
12028 (unreadpure): Remove function.
12029 (readevalloop): Don't call read_list with -1 flag.
12030 (read1, read_vector): Don't test read_pure any more.
12031 (read_list): Simplify.
12033 * fileio.c, character.h: Minor style tweaks.
12035 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12037 * window.h (clip_changed): Remove useless declaration.
12039 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12041 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12042 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12044 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12047 This directory predates autoconf and is no longer needed nowadays.
12048 Move its few remaining bits of functionality to where they're needed.
12049 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12050 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12051 * m/template.h: Remove.
12052 * Makefile.in (M_FILE): Remove. All uses removed.
12053 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12054 * lisp.h (USE_LSB_TAG):
12055 * mem-limits.h (EXCEEDS_LISP_PTR):
12056 Use VAL_MAX, not VALBITS, in #if.
12057 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12058 (EMACS_UINT): Define unconditionally now.
12059 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12060 (BITS_PER_EMACS_INT): New constants, replacing
12061 what used to be in config.h, but not useful in #if.
12062 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12063 define them any more.
12064 (VAL_MAX): New macro.
12066 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12067 BITS_PER_EMACS_INT, in #if.
12068 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12069 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12070 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12071 * s/ms-w32.h (DATA_START):
12072 Move here from removed file m/intel386.h.
12073 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12074 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12076 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12078 Assume C89 or later.
12079 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12080 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12082 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12083 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12084 * textprop.c, tparam.c (NULL): Remove.
12085 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12086 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12087 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12088 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12089 * xterm.c (input_signal_count): Assume volatile works.
12091 2012-05-21 Ken Brown <kbrown@cornell.edu>
12093 * xgselect.c (xg_select): Fix first argument in call to 'select'
12096 2012-05-20 Ken Brown <kbrown@cornell.edu>
12098 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12099 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12101 2012-05-19 Ken Brown <kbrown@cornell.edu>
12103 * xfns.c (x_in_use): Remove `static' qualifier.
12104 * xterm.h (x_in_use): Declare.
12105 * xgselect.c: Include xterm.h.
12106 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12107 and `display_arg' (bug#9754).
12109 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12111 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12113 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12114 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12116 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12118 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12120 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12121 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12123 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12124 reference to image_cache->refcount.
12125 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12127 2012-05-17 Juri Linkov <juri@jurta.org>
12129 * search.c (Fword_search_regexp, Fword_search_backward)
12130 (Fword_search_forward, Fword_search_backward_lax)
12131 (Fword_search_forward_lax): Move functions to isearch.el
12132 (bug#10145, bug#11381).
12134 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12136 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12138 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12140 * lread.c (init_obarray): Declare Qt and Qnil as special.
12142 2012-05-14 Glenn Morris <rgm@gnu.org>
12144 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12145 Put "libexec" before "bin", for the sake of init_callproc_1.
12147 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12149 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12151 * unexaix.c: Port to more-recent AIX compilers.
12152 (report_error, report_error_1, make_hdr, copy_sym)
12153 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12154 Make arguments const char *, not char *, to avoid violations of C
12155 standard and to fix some AIX warnings reported by Gilles Pion.
12157 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12159 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12160 already have overlays loaded.
12161 (handle_single_display_spec): Before returning without displaying
12162 fringe bitmap, synchronize the bidi iterator with the main display
12163 iterator, by calling iterate_out_of_display_property.
12164 (iterate_out_of_display_property): Detect buffer iteration by
12165 testing that it->string is a Lisp string.
12166 (get_next_display_element): When the current object is exhausted,
12167 and there's something on it->stack, call set_iterator_to_next to
12168 proceed with what's on the stack, instead of returning zero.
12169 (set_iterator_to_next): If called at the end of a Lisp string,
12170 proceed to consider_string_end without incrementing string
12171 position. Don't increment display vector index past the end of
12172 the display vector. (Bug#11417)
12173 (pos_visible_p): Don't report a position visible when move_it_to
12174 stopped at the last line of window, which happens to be scanned
12175 backwards by the bidi iteration. (Bug#11464)
12177 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12179 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12180 and right-margin display specs even if the spec is invalid or we
12181 are on a TTY, and thus unable to display on the fringes.
12182 That's because the text with the property will not be displayed anyway,
12183 so we need to signal to the caller that this is a "replacing"
12184 display spec. This fixes display when the spec is invalid or we
12187 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12189 * unexaix.c (make_hdr): Fix typo in prototype.
12190 This bug broke the build on AIX. Problem reported by Gilles Pion.
12192 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12194 * keyboard.c (kbd_buffer_get_event): Read special events also in
12195 batch mode. (Bug#11415)
12197 2012-05-12 Glenn Morris <rgm@gnu.org>
12199 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12201 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12203 * lisp.mk (lisp): Add newcomment.elc.
12205 2012-05-12 Glenn Morris <rgm@gnu.org>
12207 * Makefile.in (MKDIR_P): New, set by configure.
12208 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12210 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12212 Remove unused function hourglass_started.
12213 * dispextern.h (hourglass_started):
12214 * w32fns.c (hourglass_started):
12215 * xdisp.c (hourglass_started): Remove.
12217 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12219 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12220 Update dependencies.
12222 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12224 * xgselect.c (xg_select): Put maxfds+1 into a var.
12225 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12227 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12229 2012-05-10 Dave Abrahams <dave@boostpro.com>
12231 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12232 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12234 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12236 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12237 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12238 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12239 Initialize xd_registered_buses.
12241 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12243 Untag more efficiently if USE_LSB_TAG.
12244 This is based on a proposal by YAMAMOTO Mitsuharu in
12245 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12246 For an admittedly artificial (nth 8000 longlist) benchmark on
12247 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12248 Emacs's overall text size by 1%.
12249 * lisp.h (XUNTAG): New macro.
12250 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12251 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12252 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12253 * eval.c (Fautoload):
12254 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12255 * frame.h (XFRAME): Use XUNTAG.
12257 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12258 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12259 Remove unportable assumptions about print widths of types like
12261 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12262 intptr_t when converting between pointer and integer, to avoid GCC
12263 warnings about wrong width.
12265 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12267 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12268 stack for each reader_thread, instead of defaulting to 8MB
12269 determined by the linker. This avoids failures in creating
12270 subprocesses on Windows 7, see the discussion in this thread:
12271 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12273 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12275 Fix up display of the *Minibuf-0* buffer in the mini window.
12276 * keyboard.c (read_char): Don't clear the echo area if there's no
12278 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12279 contents of *Minibuf-0*) if there's no message displayed in its stead.
12281 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12283 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12286 2012-05-06 Chong Yidong <cyd@gnu.org>
12288 * lisp.mk (lisp): Update.
12290 2012-05-05 Jim Meyering <meyering@redhat.com>
12292 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12294 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12296 * data.c (PUT_ERROR): New macro.
12297 (syms_of_data): Use it. Add new error type `user-error'.
12298 * undo.c (user_error): New function.
12299 (Fprimitive_undo): Use it.
12300 * print.c (print_error_message): Adjust print style for `user-error'.
12301 * keyboard.c (user_error): New function.
12302 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12304 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12306 Do not limit current-time-string to years 1000..9999.
12307 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12308 (Fcurrent_time_string): Support any year that is supported by the
12309 underlying localtime representation. Don't use asctime, as it
12310 has undefined behavior for years outside the range -999..9999.
12312 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12314 Fix race conditions involving setenv, gmtime, localtime, asctime.
12315 Without this fix, interrupts could mess up code that uses these
12316 nonreentrant functions, since setting TZ invalidates existing
12317 tm_zone or tzname values, and since most of these functions return
12318 pointers to static storage.
12319 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12320 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12321 Grow the critical sections to include not just invoking
12322 localtime/gmtime, but also accessing these functions' results
12323 including their tm_zone values if any, and any related TZ setting.
12324 (format_time_string): Last arg is now struct tm *, not struct tm **,
12325 so that the struct tm is saved in the critical section.
12326 All callers changed. Simplify allocation of initial buffer, partly
12327 motivated by the fact that memory allocation needs to be outside
12328 the critical section.
12330 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12332 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12333 with RESET_INTERVAL.
12335 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12336 Remove duplicated buffer name initialization.
12338 2012-05-02 Jim Meyering <jim@meyering.net>
12340 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12342 * xfns.c (x_window): Use xstrdup (Bug#11375).
12344 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12346 * xdisp.c (pos_visible_p): If already at a newline from the
12347 display string before the 'while' loop, don't walk back the glyphs
12348 from it3.glyph_row. Solves assertion violation when the display
12349 string begins with a newline (egg.el). (Bug#11367)
12351 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12353 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12356 2012-05-01 Glenn Morris <rgm@gnu.org>
12358 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12359 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12360 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12361 All were removed before 23.1.
12363 * dispnew.c: Remove HAVE_LIBNCURSES test;
12364 it is always true on relevant platforms.
12366 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12367 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12369 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12371 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12373 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12374 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12377 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12379 Do not avoid creating empty evaporating overlays (Bug#9642).
12380 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12381 That is, do not delete an evaporating overlay if it becomes
12382 empty after its bounds are adjusted to fit within its buffer.
12383 This fix caused other problems, and I'm reverting it until we get

12390 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12392 * xdisp.c (pos_visible_p): If the window start position is beyond
12393 ZV, start the display from buffer beginning. Prevents assertion
12394 violation in init_iterator when the minibuffer window is scrolled
12395 via the scroll bar.
12397 * window.c (window_scroll_pixel_based): Likewise.
12399 2012-04-27 Chong Yidong <cyd@gnu.org>

12422 running on Windows 9X/Me.
12424 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12426 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12427 (xgetint): Add missing shift for LSB tags.

12447 Do not create empty overlays with the evaporate property (Bug#9642).
12448 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12449 if it becomes empty after its bounds are adjusted to fit within
12450 its buffer. Without this fix, in a nonempty buffer (let ((o
12451 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12452 yields an empty overlay that has the evaporate property, which is
12453 not supposed to happen.
12455 Fix minor GTK3 problems found by static checking.
12456 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12476 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12477 (__malloc_size_t, __malloc_ptrdiff_t):
12478 Remove. All uses removed, replaced by the definiens if needed,
12479 since we can assume C89 or better now.

12497 Omit no-longer-needed casts.
12498 (valloc): Use getpagesize, not __getpagesize.
12499 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

12568 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12570 * sysdep.c [__FreeBSD__]: Minor cleanups.
12571 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12572 Use Emacs indenting style more consistently. Avoid some casts.

12577 * sysdep.c (list_system_processes, system_process_attributes):
12578 Add implementation for FreeBSD (Bug#5243).

12584 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12586 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12587 It is never used otherwise.
12589 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12591 * print.c (print_preprocess): Only check print_depth if print-circle
12593 (print_object): Check for cycles even when print-circle is nil and

12598 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12599 set the status to "failed" and ensure that sentinel is run.
12601 2012-04-20 Glenn Morris <rgm@gnu.org>
12603 * process.c (Fset_process_inherit_coding_system_flag)
12604 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12654 New extern decls, to avoid calling undeclared functions.
12655 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12656 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12657 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12658 (NEED_MEM_INSERT): New macro.
12659 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12660 Remove one incorrect comment and fix another.

12727 2012-04-11 Daniel Colascione <dancol@dancol.org>
12729 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12730 against is gone. It's better to use vfork now so that when Cygwin
12731 gains a new, working vfork, we use it automatically (bug#10398).
12733 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12756 2012-04-09 Glenn Morris <rgm@gnu.org>
12758 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12759 not just in the obarray, before snarfing them. (Bug#11036)

12783 (Fdefvar): Caller changed.
12785 * callint.c (Finteractive, Fcall_interactively):
12786 * minibuf.c (Fread_variable): Callers changed.
12788 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12790 * xdisp.c (set_cursor_from_row): If the display string appears in
12791 the buffer at position that is closer to point than the position
12792 after the display string, display the cursor on the first glyph of
12793 the display string. Fixes cursor display when a 'display' text
12794 property immediately follows invisible text. (Bug#11094)
12796 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12798 composite.c: use 'double' consistently
12799 * composite.c (get_composition_id): Use 'double' consistently
12800 instead of converting 'float' to 'double' and vice versa; this is
12801 easier to understand and avoids a GCC warning.
12803 2012-04-09 Glenn Morris <rgm@gnu.org>
12805 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12806 preparation for dumping it with emacs. (Bug#4789)

12827 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12828 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12829 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12830 objects, as mark_maybe_pointer will catch them otherwise.
12831 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12832 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12850 [!WINDOWSNT]: New macros.
12851 (init_libxml2_functions, libxml2_loaded_p): New functions.
12852 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12853 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12854 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12855 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12857 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12858 Call init_libxml2_functions before calling libxml2 functions.
12859 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12861 * emacs.c: Don't include libxml/parser.h.
12862 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12863 xmlCleanupParser directly.
12865 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12867 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12869 * indent.c (Fvertical_motion): If there is a display string at
12870 point, use it.vpos to compute how many lines to backtrack after
12871 move_it_to point. (Bug#11133)
12873 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12875 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12876 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12877 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12878 macros related to unification of CJK characters. For the details,
12879 see the discussion following the message here:
12880 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12882 2012-04-04 Chong Yidong <cyd@gnu.org>
12884 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12886 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12888 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12889 instead of alloca. (Bug#11138)
12891 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

12896 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12898 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12899 position we get to after a call to move_it_to fails the
12900 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12901 only if we wind up in a string from display property. (Bug#11063)
12903 * window.c (Fdelete_other_windows_internal): Invalidate the row
12904 and column information about mouse highlight, so that redisplay
12905 restores it after reallocating the glyph matrices. (Bug#7464)
12907 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12908 string comes from a `display' text property, use the buffer
12909 position of that property as if we actually saw that position in
12911 (move_it_by_lines): Remove the assertion that
12912 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12913 violated when there's a before-string at the beginning of a line.
12916 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12918 * xdisp.c (append_space_for_newline): If the default face was
12919 remapped, use the remapped face for the appended newline.
12920 (extend_face_to_end_of_line): Use the remapped default face for
12921 extending the face to the end of the line.
12922 (display_line): Call extend_face_to_end_of_line when the default
12923 face was remapped. (Bug#11068)
12925 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12927 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12929 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12931 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12933 2012-03-27 Glenn Morris <rgm@gnu.org>
12935 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12938 2012-03-26 Kenichi Handa <handa@m17n.org>
12940 * dispextern.h (struct glyph): Fix previous change. Change the
12941 bit length of glyphless.ch to 25 (Bug#11082).

12945 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12946 (command_loop_1): Use it; inhibit selection update for
12947 handle-select-window too (Bug#8996).
12949 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12951 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12953 2012-03-25 Kenichi Handa <handa@m17n.org>
12955 * dispextern.h (struct glyph): Change the bit length of
12956 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12958 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12960 * s/ms-w32.h (tzname): Include time.h before redirecting to
12961 _tzname. Fixes the MSVC build. (Bug#9960)
12963 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12965 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12968 * xterm.c (XTread_socket): Only modify handling_signal if
12969 !SYNC_INPUT. (Bug#11080)
12971 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12973 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12974 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12975 when fetching a multibyte character consumes more bytes than
12976 CHAR_BYTES returns, due to unification of CJK characters in
12977 string_char. (Bug#11073)
12979 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12981 * process.c (wait_reading_process_output): Handle pty disconnect
12982 by refraining from sending oneself a SIGCHLD (bug#10933).

12990 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12991 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12993 2012-03-21 Chong Yidong <cyd@gnu.org>
12995 * xfaces.c (Vface_remapping_alist): Doc fix.
12997 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12999 * w32proc.c (Fw32_set_console_codepage)
13000 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

13005 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13006 to reflect default non-nil value of redisplay-dont-pause.
13008 2012-03-19 Kenichi Handa <handa@m17n.org>
13010 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13011 it fit in a valid range (Bug#11003).
13013 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13015 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13016 that is not from display property, accept the row as a "cursor
13017 row" if one of the string's character has a non-nil `cursor'
13018 property. Fixes cursor positioning when there are newlines in
13019 overlay strings, e.g. in icomplete.el. (Bug#11035)
13021 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13023 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13025 2012-03-12 Chong Yidong <cyd@gnu.org>
13027 * eval.c (inhibit_lisp_code): Rename from
13028 inhibit_window_configuration_change_hook; move from window.c.
13030 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13031 * window.c (run_window_configuration_change_hook)
13032 (syms_of_window): Callers changed.

13052 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13055 2012-03-03 Glenn Morris <rgm@gnu.org>
13057 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13059 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13061 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13062 position past the first glyph_row that ends at ZV. (Bug#10902)
13063 (redisplay_window, next_element_from_string): Fix typos in
13065 (redisplay_window): Pass to move_it_vertically the margin in
13066 pixels, not in screen lines.
13068 2012-03-02 Glenn Morris <rgm@gnu.org>
13070 * buffer.c (buffer-list-update-hook): Doc fix.
13072 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13074 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13075 push_it before setting up the iterator for the first overlay
13076 string, even if we have an empty string loaded.
13077 (next_overlay_string): If there's an empty string on the iterator
13078 stack, pop the stack. (Bug#10903)
13080 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13082 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13083 Suggested by Stefan Monnier in
13084 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13085 * alloc.c (widen_to_Lisp_Object): New static function.
13086 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13087 and widening them to Lisp_Objects. This would work even if
13088 USE_LSB_TAG is defined and wide integers are used, which might
13089 happen in a future version of Emacs.
13091 2012-02-25 Chong Yidong <cyd@gnu.org>
13093 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13096 * xselect.c (Fx_selection_exists_p): Doc fix.

13098 before saving to clipboard manager.
13100 2012-02-24 Chong Yidong <cyd@gnu.org>
13102 * keyboard.c (process_special_events): Handle all X selection
13103 requests in kbd_buffer, not just the next one (Bug#8869).
13105 2012-02-23 Chong Yidong <cyd@gnu.org>
13107 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13108 call when setting menu-bar-lines and tool-bar-lines parameters.
13109 (unwind_create_frame_1): New helper function.

13130 when computing $valmask.
13132 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13133 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13134 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13135 It's useless in that case, and it can cause problems on hosts
13136 that allocate halves of EMACS_INT values separately.
13137 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13138 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13139 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13140 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13141 it avoids undefined behavior on hosts where shifting right by more
13142 than the word width has undefined behavior.
13144 2012-02-19 Chong Yidong <cyd@gnu.org>
13146 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13147 (Funhandled_file_name_directory, Ffile_name_as_directory)
13148 (Fdirectory_file_name, Fexpand_file_name)

13164 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13166 2012-02-15 Chong Yidong <cyd@gnu.org>
13168 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

13184 2012-02-12 Chong Yidong <cyd@gnu.org>
13186 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13187 as that creates a dangerous corner case.
13189 * window.c (Fdelete_window_internal): Invalidate the mouse
13190 highlight (Bug#9904).
13192 2012-02-12 Glenn Morris <rgm@gnu.org>

13195 (Fx_get_selection_internal, Fx_disown_selection_internal)
13196 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13197 * nsselect.m (Fx_own_selection_internal)
13198 (Fx_disown_selection_internal, Fx_selection_exists_p)
13199 (Fx_selection_owner_p, Fx_get_selection_internal):
13200 Sync docs and argument specs with the xselect.c versions.
13202 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13204 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

13224 * buffer.c (Fbuffer_local_variables)
13225 (buffer_lisp_local_variables): Handle unbound vars correctly;
13226 don't let Qunbound leak into Lisp.
13228 2012-02-07 Glenn Morris <rgm@gnu.org>
13230 * image.c (Fimagemagick_types): Doc fix.
13232 * image.c (imagemagick-render-type): Change it from a lisp object
13233 to an integer. Move the doc here from the lisp manual.

13262 * keyboard.c (adjust_point_for_property): Don't position point
13263 before BEGV. (Bug#10696)
13265 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13267 Handle overflow when computing char display width (Bug#9496).
13268 * character.c (char_width): Return EMACS_INT, not int.
13269 (char_width, c_string_width): Check for overflow when
13270 computing the width; this is possible now that individual
13271 characters can have unbounded width. Problem introduced
13272 by merge from Emacs 23 on 2012-01-19.
13274 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13807 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13808 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13809 this macro definition.
13811 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

13836 * xdisp.c (redisplay_window): If cursor row is not fully visible
13837 after recentering, and scroll-conservatively is set to a large
13838 number, scroll window by a few more lines to make the cursor fully
13839 visible and out of scroll-margin. (Bug#10105)
13840 (start_display): Don't move to the next line if the display should
13841 start at a newline that is part of a display vector or an overlay
13842 string. (Bug#10119)

13922 Otherwise, valgrind does not work on some platforms.
13923 Problem reported by Andreas Schwab in
13924 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13925 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13926 is set, removing the need for VIRT_ADDRESS_VARIES.
13927 (PURE_P): Use a more-efficient implementation that needs just one
13928 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13929 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13930 to 4 (xorl, subq, cmpq, setbe).
13931 * alloc.c (pure): Always extern now, since that's the

13934 consistency with the new puresize.h.
13935 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13936 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13942 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13943 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13944 behave as if the cursor position were at the window margin.
13946 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13947 and the cursor position is out of bounds, behave as if the cursor
13948 position were at the window margin. (Bug#10075)
13950 2011-11-18 Chong Yidong <cyd@gnu.org>
13952 * window.c (Fwindow_combination_limit): Make first argument

13971 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13973 * xdisp.c (row_hash): New function, body extracted from
13974 compute_line_metrics.
13975 (compute_line_metrics): Call row_hash, instead of computing the
13978 * dispnew.c (verify_row_hash): Call row_hash for computing the
13979 hash code of a row, instead of duplicating code from xdisp.c.
13981 * dispextern.h (row_hash): Add prototype.
13983 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13985 * frame.c (delete_frame): Don't delete the terminal when the last

14010 (recombine_windows, make_parent_window, make_window)
14011 (Fsplit_window_internal, saved_window)
14012 (Fset_window_configuration, save_window_save): Rename all
14013 occurrences of window_nest to window_combination_limit.
14015 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

14019 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14021 * xdisp.c (display_line): Move the call to
14022 highlight_trailing_whitespace before the call to
14023 compute_line_metrics, since the latter needs to see the final
14024 faces of all the glyphs to compute ROW's hash value.
14025 Fixes assertion violations in row_equal_p. (Bug#10035)
14027 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14029 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14030 just return (bug#10044).
14032 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14034 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14035 with user-defined heap size. Bump the default size of the temacs
14036 heap to 27MB, to avoid memory warning when running temacs.
14037 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
14039 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14040 current_matrix and desired_matrix. (Bug#9990)
14041 (verify_row_hash) [XASSERTS]: New function.
14042 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
14043 that the hash value of glyph rows is correct.

14075 avoid a crash (bug#9496).
14077 2011-11-09 Chong Yidong <cyd@gnu.org>
14079 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

14086 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14088 Avoid some portability problems by eschewing 'extern inline' functions.
14089 The trivial performance wins aren't worth the portability hassles; see
14090 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14092 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14093 (window_box_width, window_box_left, window_box_left_offset)
14094 (window_box_right, window_box_right_offset): Undo previous change,
14095 by removing the "extern"s.
14096 * intervals.c (adjust_intervals_for_insertion)
14097 (adjust_intervals_for_deletion): Undo previous change,
14098 making these static again.
14099 (offset_intervals, temp_set_point_both, temp_set_point)
14100 (copy_intervals_to_string): No longer inline.
14101 * xdisp.c (window_text_bottom_y, window_box_width)

14141 This is also needed for porting to any host where GC_MARK_STACK is
14142 not GC_MAKE_GCPROS_NOOPS.
14143 (which_symbols): Use it.
14145 2011-11-07 Kenichi Handa <handa@m17n.org>

14158 * xmenu.c (cleanup_widget_value_tree): New function.
14159 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14160 calling free_menubar_widget_value_tree directly (Bug#9830).
14162 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14164 Fix some portability problems with 'inline'.
14165 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14166 (window_box_width, window_box_left, window_box_left_offset)
14167 (window_box_right, window_box_right_offset): Declare extern.
14168 Otherwise, these inline functions do not conform to C99 and
14169 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14170 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14171 * intervals.c (adjust_intervals_for_insertion)
14172 (adjust_intervals_for_deletion): Now extern, because otherwise the
14173 extern inline functions 'offset_intervals' couldn't refer to it.
14174 (static_offset_intervals): Remove.
14175 (offset_intervals): Rewrite using the old contents of
14176 static_offset_intervals. The old version didn't conform to C99
14177 because an extern inline function contained a reference to an
14178 identifier with static linkage.

14244 official. Move initialization of image_cache_refcount and
14245 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

14285 previous/next-single-property-change returns nil, treat that as
14286 the beginning or the end of the buffer. (Bug#9955)
14288 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14290 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
14291 label is not null (Bug#9951).

14313 (mouse_face_from_buffer_pos, note_mouse_highlight):
14314 Rename cover_string to disp_string.

14324 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14325 past the beginning of the current glyph matrix.
14327 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14329 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

14373 2011-10-29 Glenn Morris <rgm@gnu.org>
14375 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14376 Not clear what it was for, and it causes various bugs. (Bug#9839)
14378 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14380 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14381 possible random value that matches one of those tested as
14382 condition to clear the mouse face.
14384 2011-10-28 Chong Yidong <cyd@gnu.org>
14386 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

14400 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14402 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14403 <oslsachem@gmail.com> for helping to debug this.
14405 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

14411 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14413 (w32font_open_internal, compute_metrics):
14414 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14415 instead of calling the "wide" APIs directly.
14417 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14419 * w32.h (syms_of_w32font): Add prototype.
14421 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14423 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14424 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14425 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14426 (Fmove_to_window_line): Doc fix.
14428 2011-10-27 Chong Yidong <cyd@gnu.org>
14430 * process.c (make_process): Set gnutls_state to NULL.
14432 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14433 non-NULL, regardless of GNUTLS_INITSTAGE.
14434 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14435 an error. Set process slots as soon as we allocate them.
14437 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14439 2011-10-27 Chong Yidong <cyd@gnu.org>
14441 * gnutls.c (emacs_gnutls_deinit): New function.

14446 (deactivate_process): Call emacs_gnutls_deinit.
14448 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14450 * image.c (x_create_x_image_and_pixmap):
14451 * w32.c (sys_rename, w32_delayed_load):
14452 * w32font.c (fill_in_logfont):

14458 extracted from Fw32_default_color_map.
14459 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14461 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14463 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14465 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14467 * keyboard.c (test_undefined): New function (bug#9751).
14468 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14470 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14472 * sysdep.c (init_sys_modes): Fix the check for the controlling
14473 terminal (Bug#6649).
14475 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14477 * dispextern.h (struct bidi_it): New member next_en_type.
14479 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14480 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14481 current character, check also for next_en_type being WEAK_EN.
14482 (bidi_resolve_weak): Don't enter the expensive loop if the current
14483 position is before next_en_pos. Record the bidi type of the first
14484 non-ET, non-BN character we find, in addition to its position.
14485 (bidi_level_of_next_char): Invalidate next_en_type when
14486 next_en_pos is over-stepped.
14488 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14490 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14491 * editfns.c: Rewrite current-time-zone so that it invokes
14492 the equivalent of (format-time-string "%Z") to get the time zone name.
14493 This fixes a bug when the time zone name contains characters that
14494 need converting from the system time locale to Emacs internal format.
14495 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14496 that patch fixed format-time-string to do the conversion, but
14497 I forgot to fix current-time-zone.
14498 (format_time_string): New function, containing most of
14499 what Fformat_time_string used to contain.
14500 (Fformat_time_string): Rewrite in terms of format_time_string.
14501 This doesn't change this function's behavior.
14502 (current-time-zone): Rewrite to use format_time_string.
14503 This fixes the bug reported by Michael Schierl in
14504 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14505 Jason Rumney's 2007-06-07 change worked around this bug, but
14507 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14509 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14511 * xdisp.c (start_display): If the character at POS is displayed
14512 via a display vector, reset IT->current.dpvec_index to zero.
14513 (try_window_reusing_current_matrix): If a line ends in a display
14514 vector or the next line starts in a display vector, continue
14515 redrawing the window even though the character position of
14516 start_row was reached.
14519 2011-10-18 Chong Yidong <cyd@gnu.org>
14521 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14522 with nobreak-char-display too.
14524 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14526 Fix part 3 of bug#9771.
14527 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14528 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14529 non-neutral characters if the current character is a paragraph
14530 separator (a.k.a. Newline). This avoids running the same
14531 expensive loop twice, once when we consume the preceding newline
14532 and the other time when the line actually needs to be displayed.
14533 Avoid the loop when we see neutrals on the base embedding level
14534 following a character whose directionality is the same as the
14535 paragraph's. This avoids running the expensive loop when a line
14536 ends in a long sequence of neutrals, like control characters.
14537 Add assertion against STRONG_AL type. Slightly rearrange code
14538 that determines the type of a neutral given the first non-neutral
14540 (bidi_level_of_next_char): Set next_en_pos to zero when
14541 invalidating its info.
14543 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14545 * xdisp.c (push_display_prop): Determine whether to record string
14546 or buffer position by IT->string, not by IT->method. Allow
14547 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14548 (move_it_vertically_backward): Don't look for character position
14549 immediately after the newline when in a continuation line.
14552 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14554 * window.c (coordinates_in_window): Rewrite and delabelize
14555 vertical border check. (Bug#5357) (Bug#9618)
14557 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14559 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14560 errors in XSetWindowBorder (bug#9310).
14562 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14564 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14565 avoid crash when xmalloc overrun checking is enabled.
14567 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14569 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14570 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14571 cursor motion with <left> and <right> arrow keys.
14573 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14574 some callers set that themselves.
14576 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14578 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14579 display string and the previous row comes from the same string and
14580 is empty. (Bug#9739) (Bug#9738)
14582 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14584 * doc.c (get_doc_string): Encode file name (bug#9735).
14586 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14588 * bidi.c (bidi_level_of_next_char):
14589 * xdisp.c (get_visually_first_element): Remove old incorrect
14590 comments regarding the Unicode Line Separator character.
14592 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14594 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14596 * alloc.c (Fgc_status): Do not access beyond zombies array
14597 boundary if nzombies > MAX_ZOMBIES.
14598 * alloc.c (dump_zombies): Add missing format specifier.
14600 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14602 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14603 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14605 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14606 Some packages use them to denote characters with modifiers.
14608 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14610 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14611 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14612 matching a pp-number. Rename parameter var to var1.
14614 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14616 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14618 2011-10-08 Glenn Morris <rgm@gnu.org>
14620 * callint.c (Fcall_interactively): Give a more explicit error for the
14621 'c' case with a non-character input. (Bug#8479)
14623 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14625 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14627 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14628 lines that are hscrolled on the left.
14630 * dispnew.c (buffer_posn_from_coords): Account for a possible
14631 presence of header-line. (Bug#4426)
14633 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14635 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14636 Don't advertise functionality which we discourage or doesn't work.
14638 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14640 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14641 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14642 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14643 this makes Emacs dump core during garbage collection on rare
14644 occasions. sizeof is obviously inferior to offsetof here, so
14645 stick with offsetof.
14646 (GC_POINTER_ALIGNMENT): New macro.
14647 (mark_memory): Omit 3rd (offset) arg; caller changed.
14648 Don't assume EMACS_INT alignment is the same as pointer alignment.
14650 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14652 * keyboard.c (read_key_sequence_remapped): New var.
14653 (read_key_sequence): Compute remapping in the right buffer.
14654 (command_loop_1): Use read_key_sequence's remapping directly.
14656 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14658 * dired.c (file_name_completion): Don't expand file name.
14659 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14660 before checking file name handler.
14662 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14663 they've been requested explicitly (bug#9591).
14665 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14667 * keymap.c (Fsingle_key_description): Use make_specified_string
14668 instead of build_string to build string from push_key_description.
14671 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14673 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14674 This fixes a Y2038 bug on 64-bit hosts.
14675 * buffer.c (reset_buffer):
14676 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14677 (Fclear_buffer_auto_save_failure):
14678 Use 0, not -1, to represent an unset failure time, since time_t
14679 might not be signed.
14681 Remove dependency on glibc malloc internals.
14682 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14683 Move back here from lisp.h, but with their new implementations.
14684 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14685 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14686 * charset.c (charset_table_init): New static var.
14687 (syms_of_charset): Use it instead of xmalloc. This removes a
14688 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14689 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14690 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14691 Move back to alloc.c.
14692 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14693 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14695 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14697 * nsterm.m (windowDidResize): Call x_set_window_size only when
14698 ns_in_resize is true. Otherwise set pixelwidth/height and
14699 call change_frame_size (Bug#9628).
14701 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14703 Port --enable-checking=all to Fedora 14 x86-64.
14704 * charset.c (syms_of_charset): Also account for glibc malloc's
14705 internal overhead when calculating the initial malloc maximum.
14707 Port --enable-checking=all to Fedora 14 x86.
14708 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14710 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14711 (overrun_check_realloc, overrun_check_free):
14712 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14713 That way, xmalloc returns a properly-aligned pointer even if
14714 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14715 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14716 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14717 into account when calculating the initial malloc maximum.
14718 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14719 Move here from alloc.c, so that charset.c can use it too.
14720 Properly align; the old code wasn't right for common 32-bit hosts
14721 when configured with --enable-checking=all.
14722 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14723 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14725 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14727 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14730 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14732 * xdisp.c (compute_display_string_end): If there's no display
14733 string at CHARPOS, return -1.
14735 * bidi.c (bidi_fetch_char): When compute_display_string_end
14736 returns a negative value, treat the character as a normal
14737 character not covered by a display string. (Bug#9624)
14739 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14741 * lread.c (Fread_from_string): Fix typo in docstring.
14743 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14745 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14746 newline, reseat the iterator instead of bidi-iterating there one
14747 character at a time. (Bug#9610)
14748 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14749 TO_CHARPOS if the bidi iterator is at base embedding level.
14751 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14753 * lread.c (readevalloop): Use correct code for NBSP.
14754 (read1): Likewise. (Bug#9608)
14756 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14758 * dbusbind.c (Fdbus_register_signal): When service is not
14759 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14761 2011-09-25 Glenn Morris <rgm@gnu.org>
14763 * buffer.c (truncate-lines): Doc fix.
14765 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14767 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14768 (Fset_window_next_buffers): Doc fix.
14770 2011-09-24 Glenn Morris <rgm@gnu.org>
14772 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14774 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14776 Fix minor problems found by static checking.
14777 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14778 * indent.c (Fvertical_motion): Fix == vs = typo.
14780 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14782 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14783 Default value is now t. Doc fix.
14785 * indent.c (Fvertical_motion): Compute and apply the overshoot
14786 logic when moving up, not only when moving down. Fix the
14787 confusing name and values of the it_overshoot_expected variable;
14788 logic changes accordingly. (Bug#9254) (Bug#9549)
14790 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14791 CHARPOS is covered by a display string which includes newlines.
14792 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14793 is covered by a display string with embedded newlines.
14795 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14797 * dbusbind.c (Fdbus_register_signal): Add match rule to
14798 Vdbus_registered_objects_table. (Bug#9581)
14799 (Fdbus_register_method, Vdbus_registered_objects_table):
14802 2011-09-24 Jim Meyering <meyering@redhat.com>
14804 do not ignore write error for any output size
14805 The previous change was incomplete.
14806 While it makes emacs --batch detect the vast majority of stdout
14807 write failures, errors were still ignored whenever the output size is
14808 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14809 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14810 && echo FAIL: ignored write error
14811 FAIL: ignored write error
14812 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14813 && echo FAIL: ignored write error
14814 FAIL: ignored write error
14815 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14817 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14819 * emacs.c (Fkill_emacs): In noninteractive mode exit
14820 non-successfully if a write error occurred on stdout. (Bug#9574)
14822 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14824 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14827 * dispextern.h (struct it): Update the comment documenting what
14830 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14832 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14833 a display string, extend search for cursor position to end of row.
14834 (find_row_edges): If the row ends in a newline from a display
14835 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14836 Handle the case of a display string with multiple newlines.
14837 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14838 non-empty line. Fixes confusing cursor motion with arrow keys at
14839 the beginning of a line that starts with whitespace.
14841 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14843 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14846 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14848 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14849 boolean (Bug#9154).
14851 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14853 * xdisp.c (display_line): Record maximum and minimum buffer
14854 positions even if no glyphs were produced (e.g., by a zero-width
14855 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14856 buffer positions that will be removed from the glyph row because
14858 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14859 column is beyond frame width: don't subtract 1 "pixel" when
14860 computing width of the stretch.
14861 (reseat_at_next_visible_line_start): Undo the change made on
14862 2011-09-17 that saved paragraph information and restored it after
14863 the call to `reseat'. (Bug#9545)
14865 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14867 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14868 and turn window cursor on if cleared (Bug#9415).
14870 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14872 * search.c (boyer_moore): Take unibyte characters from pattern
14873 literally. (Bug#9458)
14875 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14877 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14879 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14881 Fix minor problem found by static checking.
14882 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14883 initialized, to pacify gcc -Wuninitialized.
14885 * fileio.c: Report proper errno when syscall falls.
14886 (Finsert_file_contents): Save and restore errno,
14887 so that report_file_error outputs the correct diagnostic.
14888 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14890 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14892 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14894 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14896 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14897 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14899 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14901 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14902 about the current paragraph and restore it after the call to reseat.
14904 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14905 (bidi_find_paragraph_start): Search back for paragraph beginning
14906 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14907 (bidi_move_to_visually_next): Only trigger paragraph-related
14908 computations when the last character is a newline or at EOB, not
14909 just any NEUTRAL_B. (Bug#9470)
14911 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14912 truncated lines if point is covered by a display string. (Bug#9524)
14914 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14916 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14917 (cons_to_x_long): New function.
14918 (lisp_data_to_selection_data): Use it. Correct the test for
14919 short-versus-long data; it was negated. Break out of vector
14920 loop, for efficiency, when a long datum is discovered.
14922 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14924 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14926 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14928 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14929 GCC PR/17406) by declaring this function with external scope.
14931 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14933 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14934 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14936 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14938 * editfns.c (Fformat): Correctly handle text properties on "%%".
14940 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14942 * xterm.c (x_draw_composite_glyph_string_foreground):

14944 * term.c (encode_terminal_code):
14945 * composite.c (composition_update_it, get_composition_id):
14946 * xdisp.c (get_next_display_element)
14947 (fill_composite_glyph_string): Add comments about special meaning
14948 of TAB characters in a composition.
14950 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14952 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14953 This occurs when processing a multibyte format.
14954 Problem reported by Wolfgang Jenker.
14956 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14958 * xdisp.c (try_cursor_movement): Only check for exact match if
14959 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14961 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14963 Remove unused external symbols.
14964 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14965 * xdisp.c (calc_pixel_width_or_height): Now static.
14966 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14967 * indent.c (check_display_width):
14968 * w32term.c: Fix comment to match code.
14969 * xterm.c, xterm.h (x_catching_errors): Remove.
14971 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14973 * xselect.c: Use signed conversions more consistently (Bug#9498).
14974 (selection_data_to_lisp_data): Assume incoming selection data are
14975 signed integers, not unsigned. This is to be consistent with
14976 outgoing selection data, which was modified to use signed integers
14977 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14978 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14979 expects long, not unsigned long.
14981 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14983 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14984 computation of loop end. Reported by Johan Bockgård
14987 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14989 * frame.c (Fother_visible_frames_p): Function deleted.
14991 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14993 * indent.c (compute_motion): Process display vector front to back
14994 rather than the other way around. (Bug#2496)
14996 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14998 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15000 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15002 * minibuf.c (Fread_from_minibuffer): Doc fix.
15004 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15006 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15007 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15009 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15011 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15012 value for non-existent files.
15014 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15016 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15017 set its "size" to -1. This will set the modtime_size field of
15018 the corresponding buffer to -1, which is what
15019 verify-visited-file-modtime expects for files that do not exist.
15022 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15024 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15026 * lisp.h: ... from here. push_key_description is no longer
15027 defined in keyboard.c, so its declaration should not be in
15028 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15029 logically belongs with push_key_description.
15031 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15033 * buffer.h: Include <sys/types.h> instead of <time.h>.
15034 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15035 Problem reported by Herbert J. Skuhra.
15037 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15039 * xml.c (parse_region): Make the parsing work for
15040 non-comment-starting XML files again (bug#9144).
15042 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15044 * image.c (gif_load): Fix calculation of bottom and right corner.
15047 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15049 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15050 redisplay in small windows.
15052 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15054 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15056 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15058 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15059 Operate on live windows only.
15061 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15063 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15065 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15067 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15068 only under bidi iteration.
15070 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15072 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15074 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15076 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15077 Without this fix, the command to link temacs failed due to an
15078 undefined symbol __builtin_isnan. This is because
15079 /usr/include/iso/math_c99.h #defines isnan(x) to
15080 __builtin_isnan(x), but the bundled gcc, which identifies itself
15081 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15083 * floatfns.c (isnan): #undef, and then #define to a clone of
15085 (Fisnan): Always define, since it's always available now.
15086 (syms_of_floatfns): Always define isnan at the Lisp level.
15088 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15090 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15092 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15094 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15095 The previous code assumed that file offsets (off_t values) fit in
15096 EMACS_INT variables, which is not true on typical 32-bit hosts.
15097 The code messed up by falsely reporting buffer overflow in cases
15098 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15099 when "big" contains more than 2**29 bytes, even though this
15100 inserts just one byte and does not overflow the buffer.
15101 (Finsert_file_contents): Store file offsets as off_t
15102 values, not as EMACS_INT values. Check for overflow when
15103 converting between EMACS_INT and off_t. When checking for
15104 buffer overflow or for overlap, take the offsets into account.
15105 Don't use EMACS_INT for small values where int suffices.
15106 When checking for overlap, fix a typo: ZV was used where
15107 ZV_BYTE was intended.
15108 (Fwrite_region): Don't assume off_t fits into 'long'.
15109 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15111 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15113 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15115 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15117 sprintf-related integer and memory overflow issues (Bug#9412).
15119 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15120 (esprintf, exprintf, evxprintf): New functions.
15121 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15122 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15123 (modify_event_symbol): Do not assume that the length of
15124 name_alist_or_stem is safe to alloca and fits in int.
15125 (Fexecute_extended_command): Likewise for function name and binding.
15126 (Frecursion_depth): Wrap around reliably on integer overflow.
15127 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15128 since some callers pass EMACS_INT values.
15129 (Fsingle_key_description): Don't crash if symbol name contains more
15130 than MAX_ALLOCA bytes.
15131 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15132 (get_minibuffer): Arg is now EMACS_INT, not int.
15133 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15134 (esprintf, exprintf, evxprintf): New decls.
15135 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15137 * dbusbind.c (signature_cat): New function.
15138 (xd_signature, Fdbus_register_signal):
15139 Do not overrun buffer; instead, report string overflow.
15141 * dispnew.c (add_window_display_history): Don't overrun buffer.
15142 Truncate instead; this is OK since it's just a log.
15144 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15145 even if the time zone offset is outlandishly large.
15146 Don't mishandle offset == INT_MIN.
15148 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15149 when creating daemon; the previous buffer-overflow check was incorrect.
15151 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15152 which has the guts of the old verror function.
15154 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15155 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15157 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15158 (font_unparse_xlfd): Don't blindly alloca long strings.
15159 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15160 fits in int, when using sprintf. Use single snprintf to count
15161 length of string rather than counting it via multiple sprintfs;
15162 that's simpler and more reliable.
15163 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15164 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15165 sprintf, in case result does not fit in int.
15167 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15168 (fontset_from_font): Print it.
15170 * frame.c (tty_frame_count): Now printmax_t, not int.
15171 (make_terminal_frame, set_term_frame_name): Print it.
15172 (x_report_frame_params): In X, window IDs are unsigned long,
15173 not signed long, so print them as unsigned.
15174 (validate_x_resource_name): Check for implausibly long names,
15175 and don't assume name length fits in 'int'.
15176 (x_get_resource_string): Don't blindly alloca invocation name;
15177 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15180 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15181 (xg_check_special_colors, xg_set_geometry):
15182 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15184 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15185 Use esprintf, not sprintf, in case result does not fit in int.
15187 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15188 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15189 it as a large positive number.
15190 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15191 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15193 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15194 in case result does not fit in int.
15196 * print.c (float_to_string): Detect width overflow more reliably.
15197 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15198 buffer overrun. Don't assume list length fits in 'int'. Treat
15199 print length of 0 as 0, not as infinity; to be consistent with other
15200 uses of print length in this function. Don't overflow print length
15201 index. Don't assume hash table size fits in 'long', or that
15202 vectorlike size fits in 'unsigned long'.
15204 * process.c (make_process): Use printmax_t, not int, to format
15205 process-name gensyms.
15207 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15209 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15210 to avoid potential buffer overrun.
15212 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15213 if X resource line is longer than 512 bytes.
15215 * xfns.c (x_window): Make sprintf buffer a bit bigger
15216 to avoid potential buffer overrun.
15218 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15220 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15222 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15224 Integer overflow fixes for scrolling, etc.
15225 Without these, Emacs silently mishandles large integers sometimes.
15226 For example, "C-u 4294967297 M-x recenter" was treated as if
15227 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15229 * xdisp.c (try_window_id): Check Emacs fixnum range before
15230 converting to 'int'.
15232 * window.c (window_scroll_line_based, Frecenter):
15233 Check that an Emacs fixnum is in range before assigning it to 'int'.
15234 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15235 values converted from Emacs fixnums.
15236 (Frecenter): Don't wrap around a line count if it is out of 'int'
15237 range; instead, treat it as an extreme value.
15238 (Fset_window_configuration, compare_window_configurations):
15239 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15241 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15242 that can exceed INT_MAX. Check that EMACS_INT value is in range
15243 before assigning it to the (possibly-narrower) index.
15244 (match_limit): Don't assume that a fixnum can fit in 'int'.
15246 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15249 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15250 (Fvertical_motion): Don't wrap around LINES values that don't fit
15251 in 'int'. Instead, treat them as extreme values. This is good
15252 enough for windows, which can't have more than INT_MAX lines anyway.
15254 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15256 * Require libxml/parser.h to avoid compilation warning.
15258 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15260 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15261 since this reportedly can destroy thread storage.
15263 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15265 * syntax.c (find_defun_start): Update all cache variables if
15266 exiting early (Bug#9401).
15268 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15270 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15272 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15273 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15274 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15276 * term.c (tty_append_glyph): New function.
15277 (produce_stretch_glyph): Static function and its prototype deleted.
15279 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15282 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15284 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15285 when checking :margin (Bug#9390).
15286 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15287 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15288 so that the name doesn't mislead. All uses changed.
15290 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15292 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15295 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15297 * xdisp.c (move_it_to): Don't bail out early when reaching
15298 position beyond to_charpos, if we are scanning backwards.
15299 (move_it_vertically_backward): When DY == 0, make sure we get to
15300 the first character in the line after the newline.
15302 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15304 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15305 (ccl_driver): Do not generate an out-of-range pointer.
15306 (Fccl_execute_on_string): Remove unnecessary check for
15307 integer overflow, noted by Stefan Monnier in
15308 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15309 Remove a FIXME that didn't need fixing.
15310 Simplify the newly-introduced buffer reallocation code.
15312 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15314 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15316 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15318 Integer and memory overflow issues (Bug#9196).
15320 * doc.c (get_doc_string): Rework so that
15321 get_doc_string_buffer_size is the actual buffer size, rather than
15322 being 1 less than the actual buffer size; this makes xpalloc more
15325 * image.c (x_allocate_bitmap_record, cache_image):
15326 * xselect.c (Fx_register_dnd_atom):
15327 Simplify previous changes by using xpalloc.
15329 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15330 since either will do and ptrdiff_t is convenient with xpalloc.
15332 * charset.c (charset_table_size)
15333 (struct charset_sort_data.priority): Now ptrdiff_t.
15334 (charset_compare): Don't overflow if priorities differ greatly.
15335 (Fsort_charsets): Don't assume list length fits in int.
15336 Check for size-calculation overflow when allocating sort data.
15337 (syms_of_charset): Allocate an initial charset table that is
15338 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15340 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15342 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15343 The actual value is always <= INT_MAX, and leaving it unsigned made
15344 overflow checking harder.
15346 * dispextern.h (struct glyph_matrix.rows_allocated)
15347 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15348 with xpalloc. The values are still always <= INT_MAX.
15350 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15352 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15353 (SAFE_NALLOCA): New macro.
15355 * region-cache.c (struct boundary.pos, find_cache_boundary)
15356 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15357 (set_cache_region, invalidate_region_cache)
15358 (revalidate_region_cache, know_region_cache, region_cache_forward)
15359 (region_cache_backward, pp_cache):
15360 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15361 so that ptrdiff_t * can be passed to xpalloc.
15362 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15363 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15364 (pp_cache): Don't assume cache_len fits in int.
15365 * region-cache.h: Adjust extern decls to match.
15367 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15368 EMACS_INT, since either will do, for xpalloc.
15370 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15371 (xnmalloc, xnrealloc, xpalloc): New functions.
15373 * bidi.c (bidi_shelve_header_size): New constant.
15374 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15375 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15377 * bidi.c (bidi_cache_shrink):
15378 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15380 Don't update size of array until after memory allocation succeeds,
15381 because xmalloc/xrealloc may not return.
15382 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15383 now that we have proper integer overflow checking.
15384 (record_overlay_string, overlay_strings): Catch overflows when
15385 calculating size of overlay_str_buf.
15387 * callproc.c (Fcall_process): Check for size overflow when
15388 calculating size of args2.
15389 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15390 Normally we prefer signed values, but sticking with ptrdiff_t would
15391 require adding more-complicated checks.
15393 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15394 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15395 Redo buffer-overflow calculations to avoid integer overflow.
15396 Add a FIXME comment where memory seems to be over-allocated.
15398 * character.c (Fstring): Check for size-calculation overflow.
15400 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15401 unnecessary integer overflow. Check for size overflow.
15402 (encode_coding_object): Don't update size until xmalloc succeeds.
15404 * composite.c (get_composition_id): Check for overflow in glyph
15405 length calculations.
15407 Integer and memory overflow fixes for display code.
15408 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15409 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15410 (scrolling_window): Check for overflow in size calculations.
15411 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15412 Don't assume glyph table len fits in int.

15418 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15419 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15422 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15423 (get_doc_string): Check for size calculation overflow.
15424 Don't update size until allocation succeeds.
15425 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15426 EMACS_INT, where ptrdiff_t will do.
15427 (Fsubstitute_command_keys): Check for string overflow.
15429 * editfns.c (set_time_zone_rule): Don't assume environment length
15431 (message_length): Now ptrdiff_t, not int.
15432 (Fmessage_box): Don't update size until allocation succeeds.
15433 Don't assume message length fits in int.
15434 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15436 * emacs.c (main): Do not reallocate argv, since there is a null at
15437 the end that can be overwritten, and this way there's no need to
15438 worry about size-calculation overflow.
15439 (sort_args): Check for size-calculation overflow.
15441 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15443 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15445 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15446 (x_set_scroll_bar_width, x_figure_window_size):
15447 Check for integer overflow.
15448 (x_set_alpha): Do not assume XINT fits in int.
15450 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15451 This is for the members text_lines, text_cols, total_lines, total_cols,
15452 where the system imposes an 'int' limit.
15454 * fringe.c (Fdefine_fringe_bitmap):
15455 Don't update size until alloc works.
15457 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15458 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15460 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15461 Check for size-calculation overflow.
15462 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15463 do, as we prefer signed integers.
15464 (id_to_widget.max_size, id_to_widget.used)
15465 (xg_store_widget_in_map, xg_remove_widget_from_map)
15466 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15467 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15468 Use and return ptrdiff_t, not int.
15469 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15470 * gtkutil.h: Change prototypes to match the above.
15472 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15473 are duplicate now that they've been promoted to lisp.h.
15474 (x_allocate_bitmap_record, x_alloc_image_color)
15475 (make_image_cache, cache_image, xpm_load):
15476 Don't update size until alloc is done.
15477 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

15486 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15487 Use ptrdiff_t, not int, to count maps.
15488 (read_char_minibuf_menu_prompt): Check for overflow in size
15489 calculations. Don't update size until allocation succeeds.
15490 Redo calculations to avoid overflow.
15491 * keyboard.h: Change prototypes to match the above.
15493 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15495 (current_minor_maps): Check for size calculation overflow.
15496 * keymap.h: Change prototypes to match the above.
15498 * lread.c (read1, init_obarray): Don't update size until alloc done.
15500 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15519 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15520 for command line length. Do not attempt to address one before the
15521 beginning of an array, as that's not portable.
15523 * term.c (max_frame_lines): Remove; unused.
15524 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15526 (encode_terminal_code, calculate_costs): Check for size
15527 calculation overflow.

15549 Use ptrdiff_t, not int, for sizes.
15550 (Finternal_make_lisp_face, cache_face):
15551 Check for size calculation overflow.
15552 (cache_face): Treat size calculation overflows as if they were
15553 memory exhaustion (the usual treatment), rather than aborting.
15555 * xfns.c (x_encode_text, x_set_name_internal)
15556 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15557 sizes, since they can exceed INT_MAX in size. Check for size
15558 calculation overflow.
15560 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15561 (xg_select): Check for size calculation overflow.
15562 Don't update size until alloc done.
15564 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15565 as sprintf is limited to int lengths.
15567 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15568 (X_LONG_MIN): New macros.
15569 Use them to make the following changes clearer.
15570 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15571 This change doesn't affect the value now, but it may help remind
15572 future maintainers not to raise the value too much later.
15573 (SELECTION_QUANTUM): Remove, replacing with ...
15574 (selection_quantum): ... new function, which avoids overflow.
15576 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15577 assumption that selection length fits in 'int'.

15584 (receive_incremental_selection, x_property_data_to_lisp):
15585 Redo calculations to avoid overflow.
15586 (x_reply_selection_request): When sending hint, ceiling it at
15587 X_LONG_MAX rather than relying on wraparound overflow to send
15589 (x_get_window_property, receive_incremental_selection)
15590 (lisp_data_to_selection_data, x_property_data_to_lisp):
15591 Check for size-calculation overflow.
15592 (x_get_window_property, receive_incremental_selection)

15594 Don't store size until memory allocation succeeds.
15595 (x_get_window_property): Plug memory leak on memory exhaustion.
15596 Don't double-block input; malloc is safe here. Don't assume 2**34
15597 - 4 fits in unsigned long. Add an xassert to check
15598 XGetWindowProperty overflow. Be more careful about overflow
15599 calculations, and distinguish size from memory overflow better.
15600 (receive_incremental_selection): When tracing, don't assume
15601 unsigned int is less than INT_MAX.
15602 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15603 harmful) conversions of unsigned short to int.
15604 (lisp_data_to_selection_data): Don't assume that integers
15605 in the range -65535 through -1 fit in an X unsigned short.
15606 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15607 result parameters unless successful. Rely on cons_to_unsigned
15608 to report problems with elements; the old code wasn't right anyway.
15609 (x_check_property_data): Check for int overflow; we cannot use
15610 a wider type due to X limits.
15611 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15613 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15616 (x_term_init): Check for size calculation overflow.
15617 (x_color_cells): Don't store size until memory allocation succeeds.
15618 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15619 Don't assume alloca size is less than MAX_ALLOCA.
15620 (x_term_init): Don't assume length fits in int (sprintf is limited
15623 Use ptrdiff_t for composition IDs.

15642 * image.c (xpm_get_color_table_h):
15643 * lisp.h (hash_lookup, hash_put):
15644 * minibuf.c (Ftest_completion):
15645 Use ptrdiff_t for hash table indexes, not int (which is too
15646 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15647 32-bit --with-wide-int hosts).
15649 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15650 Add a FIXME comment about memory leaks.
15651 (syms_of_charset): Don't assume xmalloc returns.

15655 * character.h (CHAR_WIDTH):
15656 * indent.c (MULTIBYTE_BYTES_WIDTH):
15657 Use sanitize_char_width to avoid undefined and/or bad behavior
15658 with outlandish widths.
15659 * character.h (sanitize_tab_width): Rename from sanitize_width,
15660 now that we have two such functions. All uses changed.
15661 (sanitize_char_width): New inline function.
15663 Don't assume that tab-width fits in int.
15664 * character.h (sanitize_width): New inline function.
15665 (SANE_TAB_WIDTH): New macro.
15666 (ASCII_CHAR_WIDTH): Use it.
15667 * indent.c (sane_tab_width): Remove. All uses replaced by
15668 SANE_TAB_WIDTH (current_buffer).

15671 * fileio.c: Integer overflow issues with file modes.
15672 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15674 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15675 Remove unreachable code.
15676 (read_hex, load_charset_map_from_file): Check for integer overflow.
15678 * xterm.c: Don't go over XClientMessageEvent limit.
15679 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15680 (x_send_scroll_bar_event): Likewise. Check that the size does not
15681 exceed limits imposed by XClientMessageEvent, as well as the usual
15682 ptrdiff_t and size_t limits.
15684 * keyboard.c: Overflow, signedness and related fixes.
15685 (make_lispy_movement): Use same integer type in forward decl
15686 that is used in the definition.
15687 (read_key_sequence, keyremap_step):
15688 Change bufsize argument back to int, undoing my 2011-03-30 change.
15689 We prefer signed types, and int is wide enough here.
15690 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15691 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15692 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15693 length, not size_t. Use ptrdiff_t for index, not int.
15694 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15695 possibility of integer overflow.
15697 Overflow, signedness and related fixes for images.
15699 * dispextern.h (struct it.stack[0].u.image.image_id)

15718 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15719 (lookup_image): Remove unnecessary tests.
15720 (xbm_image_p): Locals are now of int, not EMACS_INT,
15721 since parse_image_check makes sure they fit into int.
15722 (png_load, gif_load, svg_load_image):
15723 Prefer int to unsigned where either will do.
15724 (tiff_handler): New function, combining the cores of the
15725 old tiff_error_handler and tiff_warning_handler.
15726 This function is rewritten to use vsnprintf and thereby avoid
15727 stack buffer overflows. It uses only the features of vsnprintf
15728 that are common to both POSIX and native Microsoft.
15729 (tiff_error_handler, tiff_warning_handler): Use it.
15730 (tiff_load, gif_load, imagemagick_load_image):
15731 Don't assume :index value fits in 'int'.
15732 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15733 (imagemagick_load_image): Check that crop parameters fit into
15734 the integer types that MagickCropImage accepts. Don't assume
15735 Vimagemagick_render_type has a nonnegative value. Don't assume
15736 size_t fits in 'long'.
15737 (gs_load): Use printmax_t to print the widest integers possible.
15738 Check for integer overflow when computing image height and width.
15740 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15742 * xdisp.c (redisplay_window): Don't force window start if point
15743 will be invisible in the resulting window. (Bug#9324)

15747 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15748 the display spec is of the form `(space ...)'.
15749 (handle_display_spec): Return the value returned by
15750 handle_single_display_spec, not just 1 or zero.
15751 (handle_single_display_spec): If the display spec is of the form
15752 `(space ...)', and specifies display in the text area, return 2
15754 (try_cursor_movement): Check for the need to scroll more
15755 accurately, and prefer exact match for point under bidi.
15756 Don't advance `row' beyond the last row of the window.
15758 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15759 into disp_prop; all users changed.
15761 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15762 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15763 for the text covered by the display property.

15773 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15774 buffers, return left-to-right.
15775 (set_cursor_from_row): Consider candidate row a win if its glyph
15776 represents a newline and point is on that newline. Fixes cursor
15777 positioning on the newline at EOL of R2L text within L2R
15778 paragraph, and vice versa.
15779 (try_cursor_movement): Check continued rows, in addition to
15780 continuation rows. Fixes unwarranted scroll when point enters a
15781 continued line of R2L text within an L2R paragraph, or vice versa.
15782 (cursor_row_p): Consider the case of point being equal to
15783 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15784 from the end of a short line to the beginning of a continued line
15785 of R2L text within L2R paragraph.
15786 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15787 composed characters.

15802 2011-08-22 Kenichi Handa <handa@m17n.org>
15804 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15805 extra slot even if the purpose is char-code-property-table.
15807 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15809 * xdisp.c (redisplay_window): When computing centering_position,
15810 account for the height of the header line. (Bug#8874)
15812 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15813 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15814 candidate is selected by the mouse, and that candidate has a
15815 composed character under the mouse.
15817 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15818 coordinates reported by pos-visible-in-window-p for a composed
15819 character in column zero.
15821 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15823 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15825 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15827 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15828 consider it a hit if to_charpos is anywhere in the range of the
15829 composed buffer positions.
15831 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15833 * image.c (gif_load): Don't assume that each subimage has the same
15834 dimensions as the base image. Handle disposal method that is
15835 "undefined" by the gif spec (Bug#9335).
15837 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15839 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15842 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15844 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15845 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15846 from an Org mode buffer to a Speedbar frame.
15848 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15849 a composition, take its buffer position from IT->cmp_it.charpos.
15850 Fixes cursor positioning at the beginning of a line that begins
15851 with a composed character.
15853 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15855 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15856 character bidirectional type, use STRONG_L instead. Fixes crashes
15857 in a buffer produced by `describe-categories'.
15859 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15860 members before the level stack, so they would be saved and
15861 restored when copying iterator state. Fixes incorrect reordering
15862 around TABs covered by display properties.
15864 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15866 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15871 (internal_condition_case_2, internal_condition_case_n):
15872 Remove unnecessary aborts (Bug#9081).
15874 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15876 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15877 has no `load' handler, try opening the file locally. (Bug#9311)
15879 2011-08-16 Ken Brown <kbrown@cornell.edu>

15885 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15886 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15888 2011-08-16 Ken Brown <kbrown@cornell.edu>
15890 Fix memory allocation problems in Cygwin build (Bug#9273).
15892 * unexcw.c ( __malloc_initialized): Declare external variable.
15893 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15895 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15897 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15934 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15936 * xdisp.c (move_it_in_display_line_to): Don't invoke
15937 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15938 ppos_it. Fixes vertical cursor motion when line beginning is
15939 covered by an image. (Bug#9296)
15941 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15943 * nsterm.h (ns_run_ascript): Declare.

15946 * nsfns.m (as_script, as_result, as_status): New static variables.
15947 (ns_run_ascript): New function.
15948 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15949 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15950 the event loop. Get status from as_status (Bug#7276).
15952 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15953 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15954 the event loop (Bug#7276).
15956 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15958 * gnutls.c (QCgnutls_bootprop_priority)

15979 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15980 (Fnetwork_interface_list): Allocate in increments of bytes instead
15981 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15982 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15984 (struct ifflag_def): notrailers is smart on OSX.
15985 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15986 Get hardware address with getifaddrs if available.
15988 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15990 * xdisp.c (iterate_out_of_display_property): xassert that
15991 IT->position is set to within IT->object's boundaries. Break from
15992 the loop as soon as EOB is reached; avoids infloops in redisplay
15993 when IT->position is set up wrongly due to some bug.
15994 Set IT->current to match the bidi iterator unconditionally.
15995 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15996 entry. Force push_it to save on the stack the current
15997 buffer/string position, to be restored by pop_it. Fix flags in
15998 the iterator structure wrt the object coming from a display
15999 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16000 properties. (Bug#9284)
16002 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16004 * fontset.c (fontset_get_font_group): Add proper type checks.

16017 no-display-properties-and-no-overlays under bidi display.
16018 Set disp_pos in the bidi iterator to avoid searches for display
16019 properties and overlays.

16027 the font entity extracted from the cache (Bug#8109).
16029 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16031 * composite.c (autocmp_chars): Don't reset point. That is done by
16032 restore_point_unwind (Bug#5984).
16034 2011-08-07 Juri Linkov <juri@jurta.org>
16036 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16037 to show the arg `TIME' instead of `TIMEVAL'.
16039 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16041 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16042 display property strides EOL and includes a newline, as in
16043 longlines-mode. (Bug#9254)
16044 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16045 word-wrap under bidirectional display. (Bug#9224)
16047 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16048 is non-zero, even if the data buffer is NULL. Fixes a crash in
16049 vertical-motion with longlines-mode. (Bug#9254)
16051 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16053 * bidi.c <bidi_cache_total_alloc>: Now static.
16054 (bidi_initialize): Initialize bidi_cache_total_alloc.
16056 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16059 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16060 amount allocated this far in `bidi_cache_total_alloc'.
16061 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16062 non-zero, only free the data buffer without restoring the cache
16063 contents. All callers changed.
16065 * dispextern.h (bidi_unshelve_cache): Update prototype.
16067 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16068 (move_it_in_display_line, move_it_to)
16069 (move_it_vertically_backward, move_it_by_lines): Replace the call
16070 to xfree to an equivalent call to bidi_unshelve_cache.
16071 (move_it_in_display_line_to): Fix logic of returning
16072 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16074 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16076 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16077 came from a string character with a `cursor' property. (Bug#9229)
16079 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16081 * Makefile.in (LIB_PTHREAD): New variable.
16082 (LIBES): Add LIB_PTHREAD (Bug#9216).
16084 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16085 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16087 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16089 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16091 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16093 * xterm.c (x_find_topmost_parent): New function.
16094 (x_set_frame_alpha): Find topmost parent window with
16095 x_find_topmost_parent and set the property there also (bug#9181).
16096 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16098 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16100 * callproc.c (Fcall_process): Avoid vfork clobbering
16101 the local vars buffer, coding_systems, current_dir.
16103 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16105 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16107 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16109 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16110 so that it is not optimized away.
16112 * xdisp.c (compute_display_string_pos): Remove unused local.
16114 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16116 Fix slow cursor motion and scrolling in large buffers with
16117 selective display, like Org Mode buffers. (Bug#9218)
16119 * dispextern.h (struct bidi_it): New member disp_prop_p.
16121 * xdisp.c: Remove one-slot cache of display string positions.
16122 (compute_display_string_pos): Accept an additional argument
16123 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16124 for a display string or property. If found, set DISP_PROP_P
16127 * bidi.c (bidi_fetch_char): Accept an additional argument
16128 DISP_PROP_P, and pass it to compute_display_string_pos.
16129 Only handle text covered by a display string if DISP_PROP_P is returned
16130 non-zero. All callers of bidi_fetch_char changed.
16132 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16134 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16136 2010-12-03 Don March <don@ohspite.net>
16138 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16139 last character M-[char] is translated to ESC [char] (bug#7541).
16141 2011-08-02 Kenichi Handa <handa@m17n.org>
16143 * lisp.h (uniprop_table): Extern it.
16145 * chartab.c (uniprop_table): Make it non-static.
16147 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16149 * xdisp.c (forward_to_next_line_start): Accept additional argument
16150 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16152 (reseat_at_next_visible_line_start): Use the bidi iterator state
16153 returned by forward_to_next_line_start to restore the state of
16154 it->bidi_it after backing up to previous newline. (Bug#9212)
16156 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16158 * regex.c (re_comp): Protoize.
16159 (re_exec): Fix return type.
16160 (regexec): Fix type of `ret'. (Bug#9203)
16162 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16164 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16165 This is needed if max-image-size is a floating-point number.
16167 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16169 * print.c (print_object): Print empty symbol as ##.
16171 * lread.c (read1): Read ## as empty symbol.
16173 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16175 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16176 setting frame foreground color (Bug#9175).
16177 (x_set_background_color): Likewise.
16179 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16180 contents (Bug#9176).
16181 (EmacsTooltip -init): Remove bezels and add shadows to
16184 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16185 or scroll bar (Bug#8470).
16187 * nsfont.m (nsfont_open): Remove assignment to voffset and
16188 unnecessary vars hshink, expand, hd, full_height, min_height.
16189 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16191 * nsterm.h (nsfont_info): Remove voffset field.
16193 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16195 Implement strike-through and overline on NextStep (Bug#8863).
16197 * nsfont.m (nsfont_open): Use underline position provided by font,
16198 instead of hard-coded value of 2.
16199 (nsfont_draw): Call ns_draw_text_decoration instead.
16201 * nsterm.h: Add declaration for ns_draw_text_decoration.
16203 * nsterm.m (ns_draw_text_decoration): New function for drawing
16204 underline, overline, and strike-through.
16205 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16206 ns_draw_text_decoration. Change treatment of cursor drawing to
16207 accommodate underlining, etc.
16209 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16211 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16214 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16216 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16217 Without this fix, if a signal arrives just after memory fills up,
16218 'malloc' might be invoked reentrantly.
16220 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16221 In other words, assume that every image size is allowed, on non-X
16222 hosts. This assumption is probably wrong, but it lets Emacs compile.
16224 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16226 * regex.c (re_iswctype): Convert return values to boolean.
16228 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16230 * xdisp.c (compute_display_string_pos): Don't use cached display
16231 string position if the buffer had its restriction changed.
16234 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16236 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16238 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16240 Integer signedness and overflow and related fixes. (Bug#9079)
16242 * bidi.c: Integer size and overflow fixes.
16243 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16244 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16245 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16246 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16247 (bidi_find_other_level_edge):
16248 Use ptrdiff_t instead of EMACS_INT where either will do.
16249 This works better on 32-bit hosts configured --with-wide-int.
16250 (bidi_cache_ensure_space): Check for size-calculation overflow.
16251 Use % rather than repeated addition, for better worst-case speed.
16252 Don't set bidi_cache_size until after xrealloc returns, because it
16254 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16255 (bidi_cache_ensure_space): Also check that the bidi cache size
16256 does not exceed that of the largest Lisp string or buffer. See Eli
16257 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16259 * alloc.c (__malloc_size_t): Remove.
16260 All uses replaced by size_t. See Andreas Schwab's note
16261 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16263 * image.c: Improve checking for integer overflow.
16264 (check_image_size): Assume that f is nonnull, since
16265 it is always nonnull in practice. This is one less thing to
16266 worry about when checking for integer overflow later.
16267 (x_check_image_size): New function, which checks for integer
16268 overflow issues inside X.
16269 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16270 This removes the need for a memory_full check.
16271 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16272 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16273 (xbm_read_bitmap_data): Change locals back to 'int', since
16274 their values must fit in 'int'.
16275 (xpm_load_image, png_load, tiff_load):
16276 Invoke x_create_x_image_and_pixmap earlier,
16277 to avoid much needless work if the image is too large.
16278 (tiff_load): Treat overly large images as if
16279 x_create_x_image_and_pixmap failed, not as malloc failures.
16280 (gs_load): Use x_check_image_size.
16282 * gtkutil.c: Omit integer casts.
16283 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16284 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16286 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16288 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16289 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16290 would wrongly return t on a 64-bit host.
16292 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16293 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16294 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16295 and therefore cause GCC to emit a bogus diagnostic in some cases.
16297 * image.c: Integer signedness and overflow and related fixes.
16298 This is not an exhaustive set of fixes, but it's time to
16299 record what I've got.
16300 (lookup_pixel_color, check_image_size): Remove redundant decls.
16301 (check_image_size): Don't assume that arbitrary EMACS_INT values
16302 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16303 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16304 (tiff_load, imagemagick_load_image):
16305 Check for overflow in size calculations.
16306 (x_create_x_image_and_pixmap): Remove unnecessary test for
16307 xmalloc returning NULL; that can't happen.
16308 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16309 (xpm_color_bucket): Use better integer hashing function.
16310 (xpm_cache_color): Don't possibly over-allocate memory.
16311 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16312 (gif_memory_source):
16313 Use ptrdiff_t, not int or size_t, to record sizes.
16314 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16315 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16316 either works, as we prefer signed integers.
16317 (tiff_read_from_memory, tiff_write_from_memory):
16318 Return tsize_t, not size_t, since that's what the TIFF API wants.
16319 (tiff_read_from_memory): Don't fail simply because the read would
16320 go past EOF; instead, return a short read.
16321 (tiff_load): Omit no-longer-needed casts.
16322 (Fimagemagick_types): Don't assume size fits into 'int'.
16324 Improve hashing quality when configured --with-wide-int.
16325 * fns.c (hash_string): New function, taken from sxhash_string.
16326 Do not discard information about ASCII character case; this
16327 discarding is no longer needed.
16328 (sxhash-string): Use it. Change sig to match it. Caller changed.
16329 * lisp.h: Declare it.
16330 * lread.c (hash_string): Remove, since we now use fns.c's version.
16331 The fns.c version returns a wider integer if --with-wide-int is
16332 specified, so this should help the quality of the hashing a bit.
16334 * emacs.c: Integer overflow minor fix.
16335 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16336 Define only if GNU_LINUX.
16337 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16339 * dispnew.c: Integer signedness and overflow fixes.
16340 Remove unnecessary forward decls, that were a maintenance hassle.
16341 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16343 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16344 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16345 (prepare_desired_row, line_draw_cost):
16346 Use int, not unsigned, where either works.
16347 (save_current_matrix, restore_current_matrix):
16348 Use ptrdiff_t, not size_t, where either works.
16349 (init_display): Check for overflow more accurately, and without
16350 relying on undefined behavior.
16352 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16353 Remove, replacing with the new symbols in lisp.h. All uses changed.
16354 * fileio.c (make_temp_name):
16355 * filelock.c (lock_file_1, lock_file):
16356 * xdisp.c (message_dolog):
16357 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16358 Use pMd etc. instead.
16359 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16360 replacing the pWIDE etc. symbols removed from editfns.c.
16362 * keyboard.h (num_input_events): Now uintmax_t.
16363 This is (very slightly) less likely to mess up due to wraparound.
16366 * buffer.c: Integer signedness fixes.
16367 (alloc_buffer_text, enlarge_buffer_text):
16368 Use ptrdiff_t rather than size_t when either will do, as we prefer
16371 * alloc.c: Integer signedness and overflow fixes.
16372 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16373 (__malloc_size_t): Default to size_t, not to int.
16374 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16375 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16376 Prefer ptrdiff_t to size_t when either would do, as we prefer
16378 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16379 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16380 Now const. Initialize with values that are in range even if char
16382 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16383 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16384 These functions do the right thing with sizes > 2**32.
16385 (check_depth): Now ptrdiff_t, not int.
16386 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16387 Adjust to new way of storing sizes. Check for size overflow bugs
16389 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16390 slightly wrong anyway, as it missed one instance of
16391 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16392 (refill_memory_reserve): Omit needless cast to size_t.
16393 (mark_object_loop_halt): Mark as externally visible.
16395 * xselect.c: Integer signedness and overflow fixes.
16396 (Fx_register_dnd_atom, x_handle_dnd_message):
16397 Use ptrdiff_t, not size_t, since we prefer signed.
16398 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16399 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16400 x_dnd_atoms_size and x_dnd_atoms_length.
16402 * doprnt.c: Prefer signed to unsigned when either works.
16404 * doprnt.c (doprnt):
16406 * xdisp.c (vmessage):
16407 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16408 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16409 prefer signed arithmetic to avoid comparison confusion.
16410 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16411 but is a bit tricky.
16413 Assume freestanding C89 headers, string.h, stdlib.h.
16414 * data.c, doprnt.c, floatfns.c, print.c:
16415 Include float.h unconditionally.
16416 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16417 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16418 * regex.c: Likewise for stddef.h, string.h.
16419 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16420 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16421 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16422 (STDC_HEADERS): Remove obsolete defines.
16423 * sysdep.c: Include limits.h unconditionally.
16425 Assume support for memcmp, memcpy, memmove, memset.
16426 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16427 * regex.c (memcmp, memcpy):
16428 Remove; we assume C89 now.
16430 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16431 (__malloc_safe_bcopy): Remove; no longer needed.
16433 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16434 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16435 well either way, and we prefer signed to unsigned.
16437 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16439 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16440 closes the connection while we're reading (bug#9182).
16442 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16444 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16445 are specified (Bug#9168).
16447 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16449 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16450 Found by GCC static checking and --with-wide-int on a 32-bit host.
16452 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16454 * xdisp.c (compute_display_string_pos): Fix logic of caching
16455 previous display string position. Initialize cached_prev_pos to
16456 -1. Fixes slow-down at the beginning of a buffer.
16458 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16460 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16461 for attrs[LFACE_FONTSET_INDEX].
16463 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16465 * xml.c (parse_region): Remove unused local
16466 that was recently introduced.
16468 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16470 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16471 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16473 * xdisp.c (move_it_in_display_line_to): Record the best matching
16474 position for TO_CHARPOS while scanning the line, and restore it on
16475 exit if none of the characters scanned was an exact match.
16476 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16477 when exact match is impossible due to invisible text, and the
16478 lines are truncated.
16480 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16482 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16485 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16487 Fix a significant slow-down of cursor motion with C-n, C-p,
16488 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16489 auto-repeat under bidi redisplay in fontified buffers.
16490 * xdisp.c (compute_stop_pos_backwards): New function.
16491 (next_element_from_buffer): Call compute_stop_pos_backwards to
16492 find a suitable prev_stop when we find ourselves before
16494 (reseat): Don't look for prev_stop, as that could mean a very long
16496 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16497 <cached_disp_overlay_modiff>: Cache for last found display string
16499 (compute_display_string_pos): Return the cached position if asked
16500 about the same buffer in the same area of character positions, and
16501 the buffer wasn't changed since the time the display string
16502 position was cached.
16504 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16506 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16507 is an integer, which is important for empty lines. (Bug#9149)
16509 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16511 * frame.c (Fmodify_frame_parameters): In tty case, update the
16512 default face if necessary (Bug#4238).
16514 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16516 * editfns.c (Fstring_to_char): No need to explain what a character
16517 is in the docstring (Bug#6576).
16519 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16521 * xml.c (parse_region): Make sure we always return a tree.
16523 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16525 * xml.c (parse_region): If a document contains only comments,
16528 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16530 * xml.c (make_dom): Return comments, too.
16532 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16535 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16536 and the surrounding thread.
16537 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16538 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16539 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16541 * s/openbsd.h (BROKEN_SIGIO): Define.
16542 * unexelf.c (unexec) [__OpenBSD__]:
16543 Don't update the .mdebug section of the Alpha COFF symbol table.
16545 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16547 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16550 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16552 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16553 This fixes some race conditions on the permissions of any newly
16556 * alloc.c (valid_pointer_p): Use pipe, not open.
16557 This fixes some permissions issues when debugging.
16559 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16560 If fchown fails to set both uid and gid, try to set just gid,
16561 as that is sometimes allowed. Adjust the file's mode to eliminate
16562 setuid or setgid bits that are inappropriate if fchown fails.
16564 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16566 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16572 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16574 * lread.c (read_integer): Unread even EOF character.
16575 (read1): Likewise. Properly record start position of symbol.
16577 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16578 symbol character follows.
16580 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16582 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16583 This works around a problem with the previous change to Fcopy_file.
16584 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16585 and without this change, GCC might complain about discarding
16586 fchown's return value.
16588 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16590 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16592 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16594 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16596 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16598 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16599 it's used from the C level.
16601 * process.c: Use the same condition for POLL_FOR_INPUT in both
16602 keyboard.c and process.c (bug#1858).
16604 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16606 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16607 (Fgnutls_boot): Use it.
16609 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16611 * doc.c (Fsubstitute_command_keys): Revert last change.
16613 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16615 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16616 quotes the next character, and doesn't affect other longer
16617 sequences (bug#8935).
16619 * lread.c (syms_of_lread): Clarify that is isn't only
16620 `eval-buffer' and `eval-defun' that's affected by
16621 `lexical-binding' (bug#8460).
16623 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16625 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16626 bidi redisplay when a line includes both an image and is truncated.
16628 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16630 Fix minor problems found by static checking.
16631 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16632 (elsz): Now a signed constant, not a size_t var. We prefer signed
16633 types to unsigned, to avoid integer comparison confusion. Without
16634 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16635 "cannot optimize loop, the loop counter may overflow", a symptom
16637 * indent.c (Fvertical_motion): Mark locals as initialized.
16638 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16640 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16642 * search.c (Fre_search_backward): Mention `case-fold-search' in
16643 all the re_search_* functions (bug#8138).

16663 buffer position was specified. Initialize paragraph_embedding to
16665 (reseat_to_string): Initialize the bidi iterator.
16666 (display_string): If we need to ignore text properties of
16667 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16668 original value of -1 will not work with bidi.)
16669 (compute_display_string_pos): First arg is now struct
16670 `text_pos *'; all callers changed. Support display properties on
16672 (compute_display_string_end): Support display properties on Lisp
16674 (init_iterator, reseat_1, reseat_to_string): Initialize the
16675 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16676 when iterating on a string not from display properties).
16677 (compute_display_string_pos, compute_display_string_end):
16678 Fix calculation of the object to scan. Fixes an error when using
16680 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16681 base_level_stop; instead, set base_level_stop to BEGV.
16682 Fixes crashes in vertical-motion.
16683 (next_element_from_buffer): Improve commentary for when
16684 the iterator is before prev_stop.
16685 (init_iterator): Initialize bidi_p from the default value of
16686 bidi-display-reordering, not from buffer-local value. Use the
16687 buffer-local value only if initializing for buffer iteration.
16688 (handle_invisible_prop): Support invisible properties on strings
16689 that are being bidi-reordered.
16690 (set_iterator_to_next): Support bidi reordering of C strings and

16696 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16697 (init_iterator): Don't initialize it->bidi_p for strings
16699 (reseat_to_string): Initialize it->bidi_p for strings here.
16700 (next_element_from_string, next_element_from_c_string)
16701 (next_element_from_buffer): Add xassert's for correspondence

16706 character that is not the first one in the visual order.
16707 (get_visually_first_element): New function, refactored from common
16708 parts of next_element_from_buffer, next_element_from_string, and
16709 next_element_from_c_string.
16710 (tool_bar_lines_needed, redisplay_tool_bar)
16711 (display_menu_bar): Force left-to-right direction. Add a FIXME
16712 comment for making that be controlled by a user option.
16713 (push_it, pop_it): Save and restore the state of the
16714 bidi iterator. Save and restore the bidi_p flag.

16721 (get_overlay_strings_1, push_display_prop): Set up the bidi
16722 iterator for displaying display or overlay strings.
16723 (forward_to_next_line_start): Don't use the shortcut if
16725 (back_to_previous_visible_line_start): If handle_display_prop
16726 pushed the iterator stack, restore the internal state of the bidi
16727 iterator by calling bidi_pop_it same number of times.
16728 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16729 and we are bidi-iterating, don't decrement the iterator position;
16730 instead, set the first_elt flag in the bidi iterator, to produce
16732 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16733 (push_display_prop): xassert that we are iterating a buffer.
16734 (push_it, pop_it): Save and restore paragraph_embedding member.
16735 (handle_single_display_spec, next_overlay_string)
16736 (get_overlay_strings_1, reseat_1, reseat_to_string)
16737 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16738 correctly. Don't assume unibyte strings are not bidi-reordered.

16746 popping after iteration over a string that came from a display
16747 property. Fix a typo in popping stretch info. Add an assertion
16748 for verifying that the iterator position is in sync with the bidi
16750 (handle_single_display_spec, get_overlay_strings_1)
16751 (push_display_prop): Fix initialization of paragraph direction for
16752 string when that of the parent object is not yet determined.

16764 (try_scrolling, redisplay_window, display_line): Use them when
16765 saving a temporary copy of the iterator and restoring it back.
16766 (back_to_previous_visible_line_start, reseat_1)
16767 (init_iterator): Empty the bidi cache "stack".
16768 (move_it_in_display_line_to): If iterator ended up at
16769 EOL, but we never saw any buffer positions smaller than
16770 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16771 motion in bidi-reordered lines.

16775 displayed in margins. (Bug#8133) (Bug#8867)
16776 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16778 (pos_visible_p): Support positions in bidi-reordered lines.
16779 Save and restore bidi cache.
16781 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16782 (bidi_paragraph_info): Delete unused struct.

16800 Support iteration over a string.
16801 (bidi_set_sor_type, bidi_resolve_explicit_1)
16802 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16803 can now be zero (for strings); special values 0 and -1 were
16804 changed to -1 and -2, respectively.
16805 (bidi_char_at_pos): New function.
16806 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16834 * dispextern.h (struct bidi_string_data): New structure.
16835 (struct bidi_it): New member `string'. Make flag members be 1-bit

16839 (bidi_push_it, bidi_pop_it): Add prototypes.
16840 (struct iterator_stack_entry): New members bidi_p,
16841 paragraph_embedding, and from_disp_prop_p.

16889 Pass Qx_lost_selection_functions rather than
16890 Vx_lost_selection_functions to Frun_hook_with_args.
16892 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16894 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16895 The old code sometimes used this field without initializing it.
16897 * alloc.c (gc_sweep): Don't read past end of array.
16898 In theory, the old code could also have corrupted Emacs internals,
16899 though it'd be very unlikely.
16901 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
16903 * character.c (Fcharacterp): Don't advertise optional ignored

17204 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17205 subseconds part to the entropy, as that's a bit more random.
17206 Prefer signed to unsigned, since the signedness doesn't matter and
17207 in general we prefer signed. When given a limit, use a
17208 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17209 latter isn't right if USE_2_TAGS_FOR_INTS.
17210 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17211 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17224 This is more efficient than Ffile_directory_p and avoids a minor race.

17228 * buffer.c (Foverlay_put): Say what the return value is

17254 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

17356 * eval.c (struct backtrace): Simplify and port the data structure.
17357 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17358 signed bit field, as this assumption is not portable and it makes
17359 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17360 "char debug_on_exit : 1" as this is not portable either; instead,
17361 use the portable "unsigned int debug_on_exit : 1". Remove unused
17362 member evalargs. Remove obsolete comments about cc bombing out.
17364 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17432 (emacs_fixed_new): Set priv->f to argument.
17433 (emacs_fixed_get_preferred_width)
17434 (emacs_fixed_get_preferred_height): Use min_width/height from
17435 frames size_hint to set minimum and natural (Bug#8919).
17436 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17437 and use min_width/height from frames size_hint to set
17438 min_width/height (Bug#8919).
17440 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

17458 Use gnulib's dup2 module instead of rolling our own.
17459 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17461 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17463 * dispnew.c (scrolling_window): Before scrolling, turn off a

17526 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17528 Integer and buffer overflow fixes (Bug#8873).
17530 * print.c (printchar, strout): Check for string overflow.
17531 (PRINTPREPARE, printchar, strout):
17532 Don't set size unless allocation succeeds.
17534 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17535 for sizes. Check for string overflow more accurately.
17536 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17538 * macros.c: Integer and buffer overflow fixes.
17539 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17540 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17544 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17546 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17548 * lread.c: Integer overflow fixes.
17549 (read_integer): Radix is now EMACS_INT, not int,
17550 to improve quality of diagnostics for out-of-range radices.
17551 Calculate buffer size correctly for out-of-range radices.
17552 (read1): Check for integer overflow in radices, and in
17553 read-circle numbers.
17554 (read_escape): Avoid int overflow.
17555 (Fload, openp, read_buffer_size, read1)
17556 (substitute_object_recurse, read_vector, read_list, map_obarray):
17557 Use ptrdiff_t, not int, for sizes.

17572 2011-06-22 Leo Liu <sdl.web@gmail.com>
17574 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17575 Move to minibuffer.el.
17577 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17579 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17580 The following patches are for when GLYPH_DEBUG && !XASSERT.
17581 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17582 * dispnew.c (flush_stdout):
17583 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17584 Mark as externally visible.
17585 * dispnew.c (check_window_matrix_pointers): Now static.
17586 * dispnew.c (window_to_frame_vpos):
17587 * xfns.c (unwind_create_frame):
17588 * xterm.c (x_check_font): Remove unused local.
17589 * scroll.c (CHECK_BOUNDS):
17590 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17591 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17592 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17593 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17594 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17596 (debug_method_add): Use va_list and vsprintf rather than relying
17597 on undefined behavior with wrong number of arguments.
17598 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17599 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17600 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17601 since we're not interested in debugging glyphs with old libraries.
17602 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17603 GCC 4.6.0's static checking.
17605 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17607 Integer overflow and signedness fixes (Bug#8873).
17608 A few related buffer overrun fixes, too.

17618 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17619 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17621 * xfaces.c (load_pixmap):

17623 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17624 (.bitmaps_last, struct x_output.icon_bitmap):
17625 Use ptrdiff_t, not int, for bitmap indexes.
17626 (x_allocate_bitmap_record): Check for size overflow.
17627 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17629 Use ptrdiff_t, not int, for overlay counts.
17630 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17631 * editfns.c (overlays_around, get_pos_property):
17632 * textprop.c (get_char_property_and_overlay):
17633 * xdisp.c (next_overlay_change, note_mouse_highlight):
17634 * xfaces.c (face_at_buffer_position):
17635 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17636 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17637 (Fnext_overlay_change, Fprevious_overlay_change)
17638 (mouse_face_overlay_overlaps, Foverlays_in):
17639 Use ptrdiff_t, not int, for sizes.
17640 (overlays_at, overlays_in): Check for size-calculation overflow.
17642 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17644 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17645 (x_session_initialize): Do not assume string length fits in int.
17647 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17648 This is unlikely, but can occur if DPI is outlandish.
17650 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17651 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17653 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17654 * xrdb.c (magic_file_p, search_magic_path):
17655 Omit last arg SUFFIX; it was always 0. All callers changed.
17656 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17658 * xfont.c (xfont_match): Avoid need for strlen.
17660 * xfns.c: Don't assume strlen fits in int.

17663 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17664 not unsigned long, as we prefer signed integers. All callers changed.
17665 Detect integer overflow in repeat count.
17666 (message_dolog): Don't assume print length fits in 39 bytes.
17667 (display_mode_element): Don't assume strlen fits in int.
17669 * termcap.c: Don't assume sizes fit in int and never overflow.
17670 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17671 (gobble_line): Check for size-calculation overflow.
17673 * minibuf.c (Fread_buffer):
17674 * lread.c (intern, intern_c_string):
17675 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17676 Don't assume string length fits in int.

17685 Don't assume integer property fits in fixnum.
17686 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17688 * filelock.c: Fix some buffer overrun and integer overflow issues.
17689 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17690 Reformulate so as not to need the command string.
17691 Invoke gzip -cd rather than gunzip, as it's more portable.
17692 (lock_info_type, lock_file_1, lock_file):
17693 Don't assume pid_t and time_t fit in unsigned long.
17694 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17695 (current_lock_owner): Prefer signed type for sizes.
17696 Use memcpy, not strncpy, where memcpy is what is really wanted.
17697 Don't assume (via atoi) that time_t and pid_t fit in int.
17698 Check for time_t and/or pid_t out of range, e.g., via a network share.
17699 Don't alloca where an auto var works fine.
17701 * fileio.c: Fix some integer overflow issues.
17702 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17703 Don't assume string length fits in int.
17704 (directory_file_name): Don't assume string length fits in long.
17705 (make_temp_name): Don't assume pid fits in int, or that its print
17706 length is less than 20.
17708 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17710 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17712 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17714 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

17717 * emacs.c: Don't assume string length fits in 'int'.
17718 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17719 (main): Don't invoke strlen when not needed.

17725 (Fgetenv_internal):
17726 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17728 * lread.c (invalid_syntax): Omit length argument.
17729 All uses changed. This doesn't fix a bug, but it simplifies the
17730 code away from its former Hollerith-constant appearance, and it's
17731 one less 'int' to worry about when looking at integer-overflow issues.
17732 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17734 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17735 This didn't break anything, but it didn't help either.
17736 It's confusing to put a bogus integer in a place where the actual
17737 value does not matter.
17738 (LIST_END_P): Remove unused macro and its bogus comment.
17739 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17741 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17742 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17744 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17745 We prefer signed types, and the value cannot exceed the EMACS_INT
17746 range anyway (because otherwise the length would not be representable).
17747 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17748 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17749 This avoids a GCC warning when WIDE_EMACS_INT.
17751 * indent.c (sane_tab_width): New function.
17752 (current_column, scan_for_column, Findent_to, position_indentation)
17753 (compute_motion): Use it. This is just for clarity.
17754 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17756 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17758 * lisp.h (lint_assume): New macro.
17759 * composite.c (composition_gstring_put_cache):
17760 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17762 * editfns.c, insdel.c:
17763 Omit unnecessary forward decls, to simplify future changes.
17765 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17767 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17769 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17770 Use much-faster test for byte-length change.
17771 Don't assume string byte-length fits in 'int'.
17772 Check that character arg fits in 'int'.
17773 (mapcar1): Declare byte as byte, for clarity.
17775 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17777 * fns.c (concat): Catch string overflow earlier.
17778 Do not rely on integer wraparound.
17780 * dispextern.h (struct it.overlay_strings_charpos)
17781 (struct it.selective): Now EMACS_INT, not int.
17782 * xdisp.c (forward_to_next_line_start)
17783 (back_to_previous_visible_line_start)
17784 (reseat_at_next_visible_line_start, next_element_from_buffer):
17785 Don't arbitrarily truncate the value of 'selective' to int.
17787 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17789 * composite.c: Don't truncate sizes to 'int'.
17790 (composition_gstring_p, composition_reseat_it)
17791 (composition_adjust_point): Use EMACS_INT, not int.
17792 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17793 not EMACS_UINT, for indexes.
17795 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17797 * buffer.c: Include <verify.h>.
17798 (struct sortvec.priority, struct sortstr.priority):
17799 Now EMACS_INT, not int.
17800 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17801 (struct sortstr.size, record_overlay_string)
17802 (struct sortstrlist.size, struct sortlist.used):
17803 Don't truncate size to int.
17804 (record_overlay_string): Check for size-calculation overflow.
17805 (init_buffer_once): Check at compile-time, not run-time.
17807 2011-06-22 Jim Meyering <meyering@redhat.com>
17809 Don't leak an XBM-image-sized buffer
17810 * image.c (xbm_load): Free the image buffer after using it.
17812 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17815 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17816 that Sun C diagnosed.
17817 * fns.c (secure_hash): Fix pointer signedness issue.
17818 * intervals.c (static_offset_intervals): New function.
17819 (offset_intervals): Use it.
17821 2011-06-21 Leo Liu <sdl.web@gmail.com>
17824 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17827 * fns.c (secure_hash): Rename from crypto_hash_function and change
17828 the first arg to accept symbols.
17829 (Fsecure_hash): New primitive.
17830 (syms_of_fns): New symbols.
17832 2011-06-20 Deniz Dogan <deniz@dogan.se>
17834 * process.c (Fset_process_buffer): Clarify return value in
17837 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17839 * dispnew.c (add_window_display_history): Use BVAR.
17841 * xdisp.c (debug_method_add): Use BVAR.
17842 (check_window_end, dump_glyph_matrix, dump_glyph)
17843 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17845 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17848 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17849 check till after the cache is created in init_frame_faces.
17851 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17853 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17855 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17857 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17858 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17859 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17861 Improve buffer-overflow checking (Bug#8873).
17862 * fileio.c (Finsert_file_contents):
17863 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17864 Remove the old (too-loose) buffer overflow checks.
17865 They weren't needed, since make_gap checks for buffer overflow.
17866 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17867 The old code merely checked for Emacs fixnum overflow, and relied
17868 on undefined (wraparound) behavior. The new code avoids undefined
17869 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17871 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17872 Tune. Don't use wider integers than needed. Don't use alloca.
17873 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17875 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17877 * insdel.c, lisp.h (buffer_overflow): New function.
17878 (insert_from_buffer_1, replace_range, replace_range_2):
17879 * insdel.c (make_gap_larger):
17880 * editfns.c (Finsert_char):
17881 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17883 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17885 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17887 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17889 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17890 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17892 * fileio.c: Don't assume EMACS_INT fits in off_t.
17893 (emacs_lseek): New static function.
17894 (Finsert_file_contents, Fwrite_region): Use it.
17895 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17897 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17899 * fns.c: Don't overflow int when computing a list length.
17900 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17901 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17902 truncation on 64-bit hosts. Check for QUIT every
17903 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17904 faster and is responsive enough.
17905 (Flength): Report an error instead of overflowing an integer.
17906 (Fsafe_length): Return a float if the value is not representable
17907 as a fixnum. This shouldn't happen except in contrived situations.
17908 (Fnthcdr, Fsort): Don't assume list length fits in int.
17909 (Fcopy_sequence): Don't assume vector length fits in int.
17911 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17912 (header_size, word_size): New constants.
17913 (allocate_vectorlike): Don't check size overflow here.
17914 (allocate_vector): Check it here instead, since this is the only
17915 caller of allocate_vectorlike that could cause overflow.
17916 Check that the new vector's length is representable as a fixnum.
17918 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17919 The previous code was bogus. For example, next_almost_prime (32)
17920 returned 39, which is undesirable as it is a multiple of 3; and
17921 next_almost_prime (24) returned 25, which is a multiple of 5 so
17922 why was the code bothering to check for multiples of 7?
17924 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17926 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17928 Variadic C functions now count arguments with ptrdiff_t.
17929 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17930 Back then I didn't know that the Emacs coding style prefers signed int.
17931 Also, in the meantime I found a few more instances where arguments
17932 were being counted with int, which may truncate counts on 64-bit
17933 machines, or EMACS_INT, which may be unnecessarily wide.
17934 * lisp.h (struct Lisp_Subr.function.aMANY)
17935 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17936 Arg counts are now ptrdiff_t, not size_t.
17937 All variadic functions and their callers changed accordingly.
17938 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17939 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17940 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17941 * callint.c (Fcall_interactively): Check arg count for overflow,
17942 to avoid potential buffer overrun. Use signed char, not 'int',
17943 for 'varies' array, so that we needn't bother to check its size
17944 calculation for overflow.
17945 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17946 * eval.c (apply_lambda):
17947 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17948 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17949 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17951 * callint.c (Fcall_interactively): Don't use index var as event count.
17953 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17954 * mem-limits.h (SIZE): Remove; no longer used.
17956 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17958 Remove unnecessary casts.
17959 * xterm.c (x_term_init):
17960 * xfns.c (x_set_border_pixel):
17961 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17962 These aren't needed now that we assume ANSI C.
17964 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17965 It's more likely to cause problems (due to unsigned overflow)
17968 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17970 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17972 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17974 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17976 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17978 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17980 GLYPH_CODE_FACE returns EMACS_INT, not int.
17981 * dispextern.h (merge_faces):
17982 * xfaces.c (merge_faces):
17983 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17984 Don't assume EMACS_INT fits in int.
17986 * character.h (CHAR_VALID_P): Remove unused parameter.
17987 * fontset.c, lisp.h, xdisp.c: All uses changed.
17989 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17991 * fns.c (concat): Minor tuning based on overflow analysis.
17992 This doesn't fix any bugs. Use int to hold character, instead
17993 of constantly refetching from Emacs object. Use XFASTINT, not
17994 XINT, for value known to be a character. Don't bother comparing
17995 a single byte to 0400, as it's always less.
17997 * floatfns.c (Fexpt):
17998 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18000 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18003 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18005 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18006 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18007 incorrectly succeed when S was a string, because 4294967386 was
18008 truncated before it was used.
18010 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18011 Otherwise, an out-of-range integer could cause undefined behavior
18014 * composite.c: Use int, not EMACS_INT, for characters.
18015 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18016 EMACS_INT, for values that are known to be in character range.
18017 This doesn't fix any bugs but is the usual style inside Emacs and
18018 may generate better code on 32-bit machines.
18020 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18021 This is for reasons similar to the recent CHAR_STRING fix.
18022 * charset.c (Fencode_char): Check that character arg is actually
18023 a character. Pass an int to ENCODE_CHAR.
18024 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18025 wider than 'int', as a compile-time check to prevent future regressions
18028 * character.c (char_string): Remove unnecessary casts.
18030 Make sure a 64-bit char is never passed to CHAR_STRING.
18031 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18032 by silently ignoring the top 32 bits, allowing some values
18033 that were far too large to be valid characters.
18034 * character.h: Include <verify.h>.
18035 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18036 arguments are no wider than unsigned, as a compile-time check
18037 to prevent future regressions in this area.
18039 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18040 (Fsubst_char_in_region):
18042 * xdisp.c (decode_mode_spec_coding):
18043 Adjust to CHAR_STRING's new requirement.
18044 * editfns.c (Finsert_char, Fsubst_char_in_region):
18045 * fns.c (concat): Check that character args are actually
18046 characters. Without this test, these functions did the wrong
18047 thing with wildly out-of-range values on 64-bit hosts.
18049 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18050 These casts should not be needed on 32-bit hosts, either.
18051 * keyboard.c (read_char):
18052 * lread.c (Fload): Remove casts to unsigned.
18054 * lisp.h (UNSIGNED_CMP): New macro.
18055 This fixes comparison bugs on 64-bit hosts.
18056 (ASCII_CHAR_P): Use it.
18057 * casefiddle.c (casify_object):
18058 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18059 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18060 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18061 * dispextern.h (FACE_FROM_ID):
18062 * keyboard.c (read_char): Use UNSIGNED_CMP.
18064 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18065 not to EMACS_INT, to avoid GCC warning.
18067 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18069 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18070 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18071 isn't needed on 32-bit machines.
18073 * buffer.c (Fgenerate_new_buffer_name):
18074 Use EMACS_INT for count, not int.
18075 (advance_to_char_boundary): Return EMACS_INT, not int.
18077 * data.c (Qcompiled_function): Now static.
18079 * window.c (window_body_lines): Now static.
18081 * image.c (gif_load): Rename local to avoid shadowing.
18083 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18084 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18085 * alloc.c (make_save_value): Integer argument is now of type
18086 ptrdiff_t, not int.
18087 (mark_object): Use ptrdiff_t, not int.
18088 * lisp.h (pD): New macro.
18089 * print.c (print_object): Use it.
18091 * alloc.c: Use EMACS_INT, not int, to count objects.
18092 (total_conses, total_markers, total_symbols, total_vector_size)
18093 (total_free_conses, total_free_markers, total_free_symbols)
18094 (total_free_floats, total_floats, total_free_intervals)
18095 (total_intervals, total_strings, total_free_strings):
18096 Now EMACS_INT, not int. All uses changed.
18097 (Fgarbage_collect): Compute overall total using a double, so that
18098 integer overflow is less likely to be a problem. Check for overflow
18099 when converting back to an integer.
18100 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18101 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18102 These were 'int' variables that could overflow on 64-bit hosts;
18103 they were never used, so remove them instead of repairing them.
18104 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18105 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18106 Previously, this ceilinged at INT_MAX, but that doesn't work on
18108 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18110 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18111 (allocate_vectorlike): Check for ptrdiff_t overflow.
18112 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18113 when a (possibly-narrower) signed value would do just as well.
18114 We prefer using signed arithmetic, to avoid comparison confusion.
18116 * alloc.c: Catch some string size overflows that we were missing.
18117 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18118 for convenience in STRING_BYTES_MAX.
18119 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18120 The definition here is exact; the one in lisp.h was approximate.
18121 (allocate_string_data): Check for string overflow. This catches
18122 some instances we weren't catching before. Also, it catches
18123 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18124 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18125 and ptrdiff_t and EMACS_INT are both 64 bits.
18127 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18128 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18129 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18131 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18133 * alloc.c (Fmake_string): Check for out-of-range init.
18135 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18137 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18139 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18141 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18142 xg_get_default_scrollbar_width.
18144 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18145 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18146 (style_changed_cb): Call update_theme_scrollbar_width and call
18147 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18148 all frames (Bug#8505).
18149 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18150 Call gtk_window_set_resizable if HAVE_GTK3.
18151 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18152 and height if HAVE_GTK3 (Bug#8505).
18153 (scroll_bar_width_for_theme): New variable.
18154 (update_theme_scrollbar_width): New function.
18155 (xg_get_default_scrollbar_width): Move code to
18156 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18157 (xg_initialize): Call update_theme_scrollbar_width.
18159 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18161 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18163 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18165 * frame.c (make_frame): Call other_buffer_safely instead of
18168 * window.c (temp_output_buffer_show): Call display_buffer with
18169 second argument Vtemp_buffer_show_specifiers and reset latter
18170 immediately after the call.
18171 (Vtemp_buffer_show_specifiers): New variable.
18172 (auto_window_vscroll_p, next_screen_context_lines)
18173 (Vscroll_preserve_screen_position): Remove leading asterisks from
18176 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18178 Fix minor problems found by GCC 4.6.0 static checking.
18179 * buffer.c (Qclone_number): Remove for now, as it's unused.
18180 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18181 (record_buffer): Remove unused local.
18182 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18183 (set_frame_buffer_list): Remove; unused.
18184 * frame.h (other_visible_frames): Remove decl.
18185 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18186 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18187 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18189 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18190 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18191 Define only if HAVE_GPM.
18192 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18193 (update_hints_inhibit): Remove; never set. All uses removed.
18194 * widgetprv.h (emacsFrameClassRec): Remove decl.
18195 * window.c (delete_deletable_window): Now returns void, since it
18196 wasn't returning anything.
18197 (compare_window_configurations): Remove unused locals.
18198 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18199 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18200 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18201 the same widths as pointers. This follows up on the 2011-05-06 patch.
18202 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18203 * xterm.h: Likewise.
18204 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18206 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18208 * makefile.w32-in: Update dependencies.
18209 (LISP_H): Add lib/intprops.h.
18211 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18213 * image.c (gif_load): Add animation frame delay to the metadata.
18214 (syms_of_image): Use DEFSYM. New symbol `delay'.
18216 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18218 * window.c (delete_deletable_window): Re-add.
18219 (Fset_window_configuration): Rewrite to handle dead buffers and
18220 consequently deletable windows.
18221 (window_tree, Fwindow_tree): Remove. Supply functionality in

18676 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18678 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18680 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18681 in the current matrix if keep_current_p is non-zero.
18683 2011-06-04 Eli Zaretskii <eliz@gnu.org>
18685 * bidi.c (bidi_level_of_next_char): Fix last change.
18687 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18689 Support bidi reordering of text covered by display properties.
18691 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18692 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18693 (bidi_cache_search, bidi_cache_iterator_state)
18694 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18695 (bidi_level_of_next_char, bidi_move_to_visually_next):
18696 Support character positions inside a run of characters covered by a
18698 (bidi_paragraph_init, bidi_resolve_explicit_1)
18699 (bidi_level_of_next_char): Call bidi_fetch_char and
18700 bidi_fetch_char_advance instead of FETCH_CHAR and
18701 FETCH_CHAR_ADVANCE.
18702 (bidi_init_it): Initialize new members.
18703 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18705 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18706 instead of using explicit *_CHAR codes.
18707 (bidi_resolve_explicit, bidi_resolve_weak):
18708 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18709 bidirectional text is supported only in multibyte buffers.
18710 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18711 it to initialize the frame_window_p member of struct bidi_it.
18712 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18713 (bidi_resolve_explicit, bidi_resolve_weak)
18714 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
18715 bidi_it->nchars is non-positive.
18716 (bidi_level_of_next_char): Don't try to lookup the cache for the
18717 next/previous character if nothing is cached there yet, or if we
18718 were just reseat()'ed to a new position.
18720 * xdisp.c (set_cursor_from_row): Set start and stop points
18721 according to the row's direction when priming the loop that looks
18722 for the glyph on which to display cursor.
18723 (single_display_spec_intangible_p): Function deleted.
18724 (display_prop_intangible_p): Reimplement to call
18725 handle_display_spec instead of single_display_spec_intangible_p.
18726 Accept 3 additional arguments needed by handle_display_spec.
18727 This fixes incorrect cursor motion across display property with complex
18728 values: lists, `(when COND...)' forms, etc.
18729 (single_display_spec_string_p): Support property values that are
18730 lists with the argument STRING its top-level element.
18731 (display_prop_string_p): Fix the condition for processing a
18732 property that is a list to be consistent with handle_display_spec.
18733 (handle_display_spec): New function, refactored from the
18734 last portion of handle_display_prop.
18735 (compute_display_string_pos): Accept additional argument
18736 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18737 value of a `display' property is a "replacing spec".
18738 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18739 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18740 the display property, but just return a value indicating whether
18741 the display property will replace the characters it covers.
18742 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18743 frame_window_p members of struct bidi_it.
18744 (compute_display_string_pos, compute_display_string_end):
18746 (push_it): Accept second argument POSITION, where pop_it should
18747 jump to continue iteration.
18748 (reseat_1): Initialize bidi_it.disp_pos.
18750 * keyboard.c (adjust_point_for_property): Adjust the call to
18751 display_prop_intangible_p to its new signature.
18753 * dispextern.h (struct bidi_it): New member frame_window_p.
18754 (bidi_init_it): Update prototypes.
18755 (display_prop_intangible_p): Update prototype.
18756 (compute_display_string_pos, compute_display_string_end):
18757 Declare prototypes.
18758 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18761 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18763 Malloc failure behavior now depends on size of allocation.
18764 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18765 * lisp.h: Change signatures accordingly.
18766 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18767 All callers changed. (Bug#8762)
18769 * gnutls.c: Use Emacs's memory allocators.
18770 Without this change, the gnutls library would invoke malloc etc.
18771 directly, which causes problems on non-SYNC_INPUT hosts, and which
18772 runs afoul of improving memory_full behavior. (Bug#8761)
18773 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18774 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18775 xfree instead of the default malloc, realloc, free.
18776 (Fgnutls_boot): No need to check for memory allocation failure,
18777 since xmalloc does that for us.
18779 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18780 * category.c (hash_get_category_set):
18781 * ccl.c (ccl_driver):
18782 * charset.c (Fdefine_charset_internal):
18783 * charset.h (struct charset.hash_index):
18784 * composite.c (get_composition_id, gstring_lookup_cache)
18785 (composition_gstring_put_cache):
18786 * composite.h (struct composition.hash_index):
18787 * dispextern.h (struct image.hash):

18789 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18790 (hashfn_equal, hashfn_user_defined, make_hash_table)
18791 (maybe_resize_hash_table, hash_lookup, hash_put)
18792 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18793 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18794 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18795 * image.c (make_image, search_image_cache, lookup_image)
18796 (xpm_put_color_table_h):
18797 * lisp.h (struct Lisp_Hash_Table):
18798 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18799 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18800 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18801 * alloc.c (allocate_vectorlike):
18802 Check for overflow in vector size calculations.
18803 * ccl.c (ccl_driver):
18804 Check for overflow when converting EMACS_INT to int.
18805 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18806 need to be updated by these changes.
18807 * fns.c (make_hash_table, maybe_resize_hash_table):
18808 Check for integer overflow with large hash tables.
18809 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18810 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18811 (SXHASH_REDUCE): New macro.
18812 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18813 Use it instead of discarding useful hash info with large hash values.
18814 (sxhash_float): New function.
18815 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18816 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18817 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18818 Rewrite to use FIXNUM_BITS, as this simplifies things.
18819 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18820 Adjust signatures to match updated version of code.
18821 (consing_since_gc): Now EMACS_INT, since a single hash table can
18822 use more than INT_MAX bytes.
18824 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18826 Make it possible to build with GCC-4.6+ -O2 -flto.
18828 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18830 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18832 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18833 Call minibuffer-inactive-mode.
18835 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18837 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18838 Update dependencies.
18840 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18842 * data.c (init_data): Remove code for UTS, this system is not
18845 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18847 Don't force ./temacs to start in terminal mode.
18849 * frame.c (make_initial_frame): Initialize faces in all cases, not
18850 only when CANNOT_DUMP is defined.
18851 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18853 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18855 * dispnew.c (add_window_display_history): Use const for the string
18856 pointer. Remove declaration, not needed.
18858 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18860 Use 'inline', not 'INLINE'.
18861 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18862 * alloc.c, fontset.c (INLINE): Remove.
18863 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18864 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18865 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18866 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18867 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18869 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18871 Make it possible to run ./temacs.
18873 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18874 syms_of_callproc does the same thing. Remove test for
18875 "initialized", do it in the caller.
18876 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18878 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18880 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18881 (read_minibuf): Use get_minibuffer.
18882 (syms_of_minibuf): Use DEFSYM.
18883 (Qmetadata): New var.
18884 * data.c (Qbuffer): Don't make it static.
18885 (syms_of_data): Use DEFSYM.
18887 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18889 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18890 (CCL_CODE_MIN): New macro.
18892 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18894 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18896 * eval.c (Qdebug): Now static.
18897 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18898 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18899 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18901 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18903 * image.c: Various fixes to ImageMagick code comments.
18904 (Fimagemagick_types): Doc fix.
18906 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18908 Minor fixes prompted by GCC 4.6.0 warnings.
18910 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18912 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18913 (x_clipboard_manager_save_all): Move extern decl to ...
18914 * xterm.h: ... here, so that it can be checked for consistency.
18916 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18918 * xselect.c (x_clipboard_manager_save_frame)
18919 (x_clipboard_manager_save_all): New functions.
18920 (Fx_clipboard_manager_save): Lisp function deleted.
18922 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18923 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18925 * xterm.h: Update prototype.
18927 2011-05-28 William Xu <william.xwl@gmail.com>
18929 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18930 exiting (Bug#8239).
18932 2011-05-28 Jim Meyering <meyering@redhat.com>
18934 Avoid a sign-extension bug in crypto_hash_function.
18935 * fns.c (to_uchar): Define.
18936 (crypto_hash_function): Use it to convert some newly-signed
18937 variables to unsigned, to avoid sign-extension bugs. For example,
18938 without this change, (md5 "truc") would evaluate to
18939 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18940 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18941 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18943 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18945 Integer overflow fixes.
18947 * dbusbind.c: Serial number integer overflow fixes.
18948 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18949 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18950 to hold a serial number that is too large for a fixnum.
18951 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18952 Check for serial numbers out of range. Decode any serial number
18953 that was so large that it became a float. (Bug#8722)
18955 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18956 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18957 Use XFASTINT rather than XUINT when numbers are nonnegative.
18958 (xd_append_arg, Fdbus_method_return_internal):
18959 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18960 arguments, check that Lisp number is nonnegative, rather than
18961 silently wrapping negative numbers around. (Bug#8722)
18962 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18965 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18967 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18969 ccl: Add integer overflow checks.
18970 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18971 (IN_INT_RANGE): New macros.
18972 (ccl_driver): Use them to check for integer overflow when
18973 decoding a CCL program. Many of the new checks are whether XINT (x)
18974 fits in int; it doesn't always, on 64-bit hosts. The new version
18975 doesn't catch all possible integer overflows, but it's an
18976 improvement. (Bug#8719)
18978 * alloc.c (make_event_array): Use XINT, not XUINT.
18979 There's no need for unsigned here.
18981 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18982 This follows up to the 2011-05-06 change that substituted uintptr_t
18983 for EMACS_INT. This case wasn't caught back then.
18985 Rework Fformat to avoid integer overflow issues.
18986 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18987 now (part of C89). Include <verify.h>.
18988 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18989 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18990 (Fformat): Avoid the prepass trying to compute sizes; it was only
18991 approximate and thus did not catch overflow reliably. Instead, walk
18992 through the format just once, formatting and computing sizes as we go,
18993 checking for integer overflow at every step, and allocating a larger
18994 buffer as needed. Keep track separately whether the format is
18995 multibyte. Keep only the most-recently calculated precision, rather
18996 than them all. Record whether each argument has been converted to
18997 string. Use EMACS_INT, not int, for byte and char and arg counts.
18998 Support field widths and precisions larger than INT_MAX. Avoid
18999 sprintf's undefined behavior with conversion specifications such as %#d
19000 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19001 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19002 formatting out-of-range floating point numbers with int
19003 formats. (Bug#8668)
19005 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19007 * data.c: Avoid integer truncation in expressions involving floats.
19008 * data.c: Include <intprops.h>.
19009 (arith_driver): When there's an integer overflow in an expression
19010 involving floating point, convert the integers to floating point
19011 so that the resulting value does not suffer from catastrophic
19012 integer truncation. For example, on a 64-bit host (* 4
19013 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19014 Do not rely on undefined behavior after integer overflow.
19016 merge count_size_as_multibyte, parse_str_to_multibyte
19017 * character.c, character.h (count_size_as_multibyte):
19018 Rename from parse_str_to_multibyte; all uses changed.
19019 Check for integer overflow.
19020 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19021 since it's now a duplicate of the other. This is more of
19022 a character than a buffer op, so better that it's in character.c.
19023 * fns.c, print.c: Adjust to above changes.
19025 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19027 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19029 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19031 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19032 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19033 (x_clipboard_manager_save): Now static.
19034 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19036 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19037 (crypto_hash_function): Now static.
19038 Fix pointer signedness problems. Avoid unnecessary initializations.
19040 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19042 * termhooks.h (Vselection_alist): Make it terminal-local.
19044 * terminal.c (create_terminal): Initialize it.
19046 * xselect.c: Support for clipboard managers.
19047 (Vselection_alist): Move to termhooks.h as terminal-local var.
19048 (LOCAL_SELECTION): New macro.
19049 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19050 (symbol_to_x_atom): Remove gratuitous arg.
19051 (x_handle_selection_request, lisp_data_to_selection_data)
19052 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19053 (x_own_selection, x_get_local_selection, x_convert_selection):
19054 New arg, specifying work frame. Use terminal-local Vselection_alist.
19055 (some_frame_on_display): Delete unused function.
19056 (Fx_own_selection_internal, Fx_get_selection_internal)
19057 (Fx_disown_selection_internal, Fx_selection_owner_p)
19058 (Fx_selection_exists_p): New optional frame arg.
19059 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19060 (x_handle_selection_clear): Don't treat other terminals with the
19061 same keyboard specially. Use the terminal-local Vselection_alist.
19062 (x_clear_frame_selections): Use Frun_hook_with_args.
19064 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19066 * xterm.h: Add support for those atoms.
19068 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19070 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19071 (converted_selections, conversion_fail_tag): New global variables.
19072 (x_selection_request_lisp_error): Free the above.
19073 (x_get_local_selection): Remove unnecessary code.
19074 (x_reply_selection_request): Args changed; handle arbitrary array
19075 of converted selections stored in converted_selections.
19076 Separate the XChangeProperty and SelectionNotify steps.
19077 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19078 (x_convert_selection): New function.
19079 (x_handle_selection_event): Simplify.
19080 (x_get_foreign_selection): Don't ignore incoming requests while
19081 waiting for an answer; this will fail when we implement
19082 SAVE_TARGETS, and seems unnecessary anyway.
19083 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19084 (Vx_sent_selection_functions): Doc fix.
19086 2011-05-26 Leo Liu <sdl.web@gmail.com>
19088 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19090 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19092 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19094 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19095 for fringe update if it has periodic bitmap.
19096 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19097 and fringe_bitmap_periodic_p.
19099 * fringe.c (get_fringe_bitmap_data): New function.
19100 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19101 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19102 row. Mark glyph row for fringe update if periodicity changed.
19104 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19105 for fringe update unless it has periodic bitmap.
19107 2011-05-25 Kenichi Handa <handa@m17n.org>
19109 * xdisp.c (get_next_display_element): Set correct it->face_id for
19110 a static composition.
19112 2011-05-24 Leo Liu <sdl.web@gmail.com>
19115 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19117 * fns.c (crypto_hash_function, Fsha1): New function.
19118 (Fmd5): Use crypto_hash_function.
19119 (syms_of_fns): Add Ssha1.
19121 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19123 * gnutls.c: Remove unused macros.
19124 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19125 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19126 Remove macros that are defined and never used.
19127 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19129 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19131 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19132 (Fx_get_selection_internal): Minor cleanup.
19133 (Fx_own_selection_internal): Rename arguments for consistency with
19136 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19138 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19140 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19142 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19144 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19146 * dispnew.c (scrolling_window): Don't exclude the case that the
19147 last enabled row in the desired matrix touches the bottom boundary.
19149 2011-05-21 Glenn Morris <rgm@gnu.org>
19151 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19152 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19153 and add some more files.
19155 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19157 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19158 report_file_error introduced by the change from 2011-05-07.
19160 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19162 * systime.h (Time): Define only if emacs is defined.
19163 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19164 where the include path doesn't have X11/X.h by default. See
19165 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19167 2011-05-20 Kenichi Handa <handa@m17n.org>
19169 * composite.c (find_automatic_composition): Fix previous change.
19171 2011-05-20 Glenn Morris <rgm@gnu.org>
19173 * lisp.mk: New file, split from Makefile.in.
19174 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19175 (shortlisp): Remove.
19176 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19178 2011-05-19 Glenn Morris <rgm@gnu.org>
19180 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19181 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19182 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19183 (lisp): Set the order to that of loadup.el.
19184 (shortlisp): Make it a copy of $lisp.
19185 (SOME_MACHINE_LISP): Remove.
19186 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19187 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19189 2011-05-18 Kenichi Handa <handa@m17n.org>
19191 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19192 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19193 (find_automatic_composition): Mostly rewrite for efficiency.
19195 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19197 * makefile.w32-in: Update dependencies.
19199 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19201 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19202 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19204 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19206 Fix some integer overflow issues, such as string length overflow.
19208 * insdel.c (count_size_as_multibyte): Check for string overflow.
19210 * character.c (lisp_string_width): Check for string overflow.
19211 Use EMACS_INT, not int, for string indexes and lengths; in
19212 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19213 the resulting string length overflows an EMACS_INT; instead,
19214 report a string overflow if no precision given. When checking for
19215 precision exhaustion, use a check that cannot possibly have
19216 integer overflow. (Bug#8675)
19217 * character.h (lisp_string_width): Adjust to new signature.
19219 * alloc.c (string_overflow): New function.
19220 (Fmake_string): Use it. This doesn't change behavior, but saves
19221 a few bytes and will simplify future changes.
19222 * character.c (string_escape_byte8): Likewise.
19223 * lisp.h (string_overflow): New decl.
19225 Fixups, following up to the user-interface timestamp change.
19226 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19227 for UI timestamps, instead of unsigned long.
19228 * msdos.c (mouse_get_pos): Likewise.
19229 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19230 * w32gui.h (Time): Define by including "systime.h" rather than by
19231 declaring it ourselves. (Bug#8664)
19233 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19234 * image.c (clear_image_cache): Likewise.
19236 * term.c (term_mouse_position): Don't assume time_t wraparound.
19238 Be more systematic about user-interface timestamps.
19239 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19240 and sometimes 'EMACS_UINT', to represent these timestamps.
19241 This change causes it to use 'Time' uniformly, as that's what X uses.
19242 This makes the code easier to follow, and makes it easier to catch
19243 integer overflow bugs such as Bug#8664.
19244 * frame.c (Fmouse_position, Fmouse_pixel_position):
19245 Use Time, not unsigned long, for user-interface timestamps.
19246 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19247 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19248 * keyboard.h (last_event_timestamp): Likewise.
19249 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19250 * menu.h (xmenu_show): Likewise.
19251 * term.c (term_mouse_position): Likewise.
19252 * termhooks.h (struct input_event.timestamp): Likewise.
19253 (struct terminal.mouse_position_hook): Likewise.
19254 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19255 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19256 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19257 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19258 what it was before.
19259 * menu.h, termhooks.h: Include "systime.h", for Time.
19261 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19262 Don't assume that the difference between two unsigned long values
19263 can fit into an integer. At this point, we know button_down_time
19264 <= event->timestamp, so the difference must be nonnegative, so
19265 there's no need to cast the result if double-click-time is
19266 nonnegative, as it should be; check that it's nonnegative, just in
19267 case. This bug is triggered when events are more than 2**31 ms
19268 apart (about 25 days). (Bug#8664)
19270 * xselect.c (last_event_timestamp): Remove duplicate decl.
19271 (x_own_selection): Remove needless cast to unsigned long.
19273 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19274 that always fit in int. Use a sentinel instead of a counter, to
19275 avoid a temp and to allay GCC's concerns about possible int overflow.
19276 * frame.h (struct frame): Use int for menu_bar_items_used
19277 instead of EMACS_INT, since it always fits in int.
19279 * menu.c (grow_menu_items): Check for int overflow.
19281 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19283 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19284 Before, the code was not consistent. These values cannot exceed
19285 2**31 - 1 so there's no need to make them unsigned.
19286 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19287 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19288 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19290 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19292 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19293 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19294 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19295 presumably because the widths might not match.
19297 * window.c (size_window): Avoid needless test at loop start.
19299 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19301 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19303 2011-05-12 Drew Adams <drew.adams@oracle.com>
19305 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19307 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19309 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19310 `width' to `bar_area_x' and `bar_area_width', respectively.
19311 (x_scroll_run): Take account of fringe background extension.
19313 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19314 Rename local vars `left' and `width' to `bar_area_x' and
19315 `bar_area_width', respectively.
19316 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19317 background extension.
19319 2011-05-10 Jim Meyering <meyering@redhat.com>
19321 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19323 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19325 * image.c (Finit_image_library): Return t for built-in image types,
19326 like pbm and xbm. (Bug#8640)
19328 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19330 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19332 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19334 * w32console.c (Fset_screen_color): Doc fix.
19335 (Fget_screen_color): New function.
19336 (syms_of_ntterm): Defsubr it.
19338 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19339 unlink the temporary file if Fcall_process didn't create it in the
19341 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19342 child process will be redirected to a file specified with `:file'.
19343 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19344 cue to call_process_cleanup not to close that handle.
19346 2011-05-07 Ben Key <bkey76@gmail.com>
19348 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19349 one of two shell specific rules, either bootstrap-temacs-CMD or
19350 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19351 to the previous implementation of the bootstrap-temacs rule.
19352 The bootstrap-temacs-CMD rule is similar to the previous
19353 implementation of the bootstrap-temacs rule except that it
19354 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19357 These changes, along with some changes to nt/configure.bat,
19358 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19359 earlier fix to add support for --cflags and --ldflags options
19360 that include quotes so that it works whether make uses cmd or
19363 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19365 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19366 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19368 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19369 a string. Handle both cases.
19370 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19371 (Fdbus_register_method): Use Qinvalid_function.
19373 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19375 * makefile.w32-in: Update dependencies.
19376 (LISP_H): Add inttypes.h and stdin.h.
19377 (PROCESS_H): Add unistd.h.
19379 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19381 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19382 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19384 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19386 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19388 * term.c (vfatal): Remove stray call to va_end.
19389 It's not needed and the C Standard doesn't allow it here anyway.
19391 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19392 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19394 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19397 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19399 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19401 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19403 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19405 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19407 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19408 * charset.c (Fdefine_charset_internal): Don't initialize
19409 charset.code_space[15]. The value was garbage, on hosts with
19410 32-bit int (Bug#8600).
19412 * lread.c (read_integer): Be more consistent with string-to-number.
19413 Use string_to_number to do the actual conversion; this avoids
19414 rounding errors and fixes some other screwups. Without this fix,
19415 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19416 (digit_to_number): Move earlier, for benefit of read_integer.
19417 Return -1 if the digit is out of range for the base, -2 if it is
19418 not a digit in any supported base. (Bug#8602)
19420 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19422 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19423 to match comment at start of function. This also removes a
19424 GCC warning about overflow in a 32+64-bit port.
19426 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19428 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19429 Reported by Stefan Monnier in
19430 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19431 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19432 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19434 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19435 (EMACS_UINTPTR): Likewise, with uintptr_t.
19437 * lisp.h: Prefer 64-bit EMACS_INT if available.
19438 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19439 on 32-bit hosts that have 64-bit int, so that they can access
19441 However, temporarily disable this change unless the temporary
19442 symbol WIDE_EMACS_INT is defined.
19444 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19446 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19447 This removes an assumption that EMACS_INT and long are the same
19448 width as pointers. The assumption is true for Emacs porting targets
19449 now, but we want to make other targets possible.
19450 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19451 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19452 In the rest of the code, change types of integers that hold casted
19453 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19454 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19455 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19456 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19457 No need to cast type when ORing.
19458 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19459 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19460 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19461 assume EMACS_INT is the same width as char *.
19462 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19463 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19464 Remove no-longer-needed casts.
19465 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19466 (xg_tool_bar_help_callback, xg_make_tool_item):
19467 Use EMACS_INTPTR to hold an integer
19468 that will be cast to void *; this can avoid a GCC warning
19469 if EMACS_INT is not the same width as void *.
19470 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19471 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19472 (current_message_1, set_message_1):
19473 Use a local to convert to proper width without a cast.
19474 * xmenu.c (dialog_selection_callback): Likewise.
19476 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19477 Also, don't assume VALBITS / RAND_BITS is less than 5,
19478 and don't rely on undefined behavior when shifting a 1 left into
19480 * lisp.h (get_random): Change signature to match.
19482 * lread.c (hash_string): Use size_t, not int, for hash computation.
19483 Normally we prefer signed values; but hashing is special, because
19484 it's better to use unsigned division on hash table sizes so that
19485 the remainder is nonnegative. Also, size_t is the natural width
19486 for hashing into memory. The previous code used 'int', which doesn't
19487 retain enough info to hash well into very large tables.
19488 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19490 * dbusbind.c: Don't possibly lose pointer info when converting.
19491 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19492 Use XPNTR rather than XHASH, so that the high-order bits of
19493 the pointer aren't lost when converting through void *.
19495 * eval.c (Fautoload): Don't double-shift a pointer.
19497 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19499 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19501 * gnutls.c (DEF_GNUTLS_FN):
19502 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19504 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19506 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19509 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19511 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19512 New version that can reserve upto 2GB of heap space.
19514 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19516 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19518 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19520 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19521 `gnutls_certificate_set_x509_key_file'.
19523 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19525 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19526 Update dependencies.

19580 * process.c: Include lisp.h before w32.h, not after.
19581 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19582 instead of gnutls_record_check_pending.

19659 %llo or %llx format is passed. (Bug#8545)
19661 * window.c (window_scroll_line_based): Use a marker instead of
19662 simple variables to record original value of point. (Bug#7952)

19665 produced by %s or %c overflows available buffer space. (Bug#8545)
19667 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19669 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19672 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19674 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19676 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19678 * keyboard.c (Qdelayed_warnings_hook): Define.
19679 (command_loop_1): Run `delayed-warnings-hook'
19680 if Vdelayed_warnings_list is non-nil.
19681 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19682 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19684 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19686 * doprnt.c (doprnt): Don't return value smaller than the buffer
19687 size if the message was truncated. (Bug#8545).
19689 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19691 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19692 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19694 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19696 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19698 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19700 * makefile.w32-in: Update dependencies.
19702 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19704 Improve `doprnt' and its usage. (Bug#8545)
19705 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19706 `format_end'. Remove support for %l as a conversion specifier.
19707 Don't use xrealloc. Improve diagnostics when the %l size modifier
19708 is used. Update the commentary.
19710 * eval.c (verror): Simplify calculation of size_t.
19712 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19715 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19717 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19720 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19722 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19723 This makes this file independent of the recent pseudovector change.
19725 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19727 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19729 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19730 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19731 Remove unused local.
19732 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19734 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19735 GCC 4.6.0 optimizes based on type-based alias analysis.
19736 For example, if b is of type struct buffer * and v of type struct
19737 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19738 != &v->size, and therefore "v->size = 1; b->size = 2; return
19739 v->size;" must therefore return 1. This assumption is incorrect
19740 for Emacs, since it type-puns struct Lisp_Vector * with many other
19741 types. To fix this problem, this patch adds a new type struct
19742 vectorlike_header that documents the constraints on layout of vectors
19743 and pseudovectors, and helps optimizing compilers not get fooled
19744 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19745 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19746 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19748 (XSETPVECTYPE): Rewrite in terms of new macro.
19749 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19750 This is a bit clearer, and further avoids the possibility of
19751 undesirable aliasing.
19752 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19753 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19754 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19755 since Lisp_Subr is a special case (no "next" field).
19756 (ASIZE): Now uses header.size rather than size.
19757 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19758 to avoid the hassle of writing XVECTOR (foo)->header.size.
19759 (struct vectorlike_header): New type.
19760 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19761 object, to help avoid aliasing.
19762 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19763 (SUBRP): Likewise, since Lisp_Subr is a special case.
19764 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19765 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19766 (struct Lisp_Hash_Table): Combine first two members into a single
19767 struct vectorlike_header member. All uses of "size" and "next" members
19768 changed to be "header.size" and "header.next".
19769 * buffer.h (struct buffer): Likewise.
19770 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19771 * frame.h (struct frame): Likewise.
19772 * process.h (struct Lisp_Process): Likewise.
19773 * termhooks.h (struct terminal): Likewise.
19774 * window.c (struct save_window_data, struct saved_window): Likewise.
19775 * window.h (struct window): Likewise.
19776 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19777 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19778 * buffer.c (init_buffer_once): Likewise.
19779 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19781 * process.c (Fformat_network_address): Use local var for size,
19784 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19786 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19787 * data.c (atof): Remove decl; no longer used or needed.
19788 (digit_to_number): Move to lread.c.
19789 (Fstring_to_number): Use new string_to_number function, to be
19790 consistent with how the Lisp reader treats infinities and NaNs.
19791 Do not assume that floating-point numbers represent EMACS_INT
19792 without losing information; this is not true on most 64-bit hosts.
19793 Avoid double-rounding errors, by insisting on integers when
19794 parsing non-base-10 numbers, as the documentation specifies.
19795 * lisp.h (string_to_number): New decl, replacing ...
19796 (isfloat_string): Remove.
19797 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19798 (read1): Do not accept +. and -. as integers; this
19799 appears to have been a coding error. Similarly, do not accept
19800 strings like +-1e0 as floating point numbers. Do not report
19801 overflow for integer overflows unless the base is not 10 which
19802 means we have no simple and reliable way to continue.
19803 Break out the floating-point parsing into a new
19804 function string_to_number, so that Fstring_to_number parses
19805 floating point numbers consistently with the Lisp reader.
19806 (digit_to_number): Move here from data.c. Make it static inline.
19807 (E_CHAR, EXP_INT): Remove, replacing with ...
19808 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19809 (string_to_number): New function, replacing isfloat_string.
19810 This function checks for valid syntax and produces the resulting
19811 Lisp float number too. Rework it so that string-to-number
19812 no longer mishandles examples like "1.0e+". Use strtoumax,
19813 so that overflow for non-base-10 numbers is reported only when
19814 there's no portable and simple way to convert to floating point.
19816 * textprop.c (set_text_properties_1): Rewrite for clarity,
19817 and to avoid GCC warning about integer overflow.
19819 * intervals.h (struct interval): Use EMACS_INT for members
19820 where EMACS_UINT might cause problems. See
19821 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19822 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19823 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19825 (offset_intervals): Tell GCC not to worry about length overflow
19826 when negating a negative length.
19828 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19829 (overrun_check_free): Likewise.
19831 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19832 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19835 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19836 (gnutls_make_error): Rename local to avoid shadowing.
19837 (gnutls_emacs_global_deinit): ifdef out; not used.
19838 (Fgnutls_boot): Use const for pointer to readonly storage.
19839 Comment out unused local. Fix pointer signedness problems.
19841 * lread.c (openp): Don't stuff size_t into an 'int'.
19842 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19843 about possible signed overflow.
19845 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19846 (GDK_KEY_g): Don't define if already defined.
19847 (xg_prepare_tooltip): Avoid pointer signedness problem.
19848 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19850 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19851 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19853 * xfns.c (Fx_window_property): Simplify a bit,
19854 to make a bit faster and to avoid GCC 4.6.0 warning.
19855 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19857 * fns.c (internal_equal): Don't assume size_t fits in int.
19859 * alloc.c (compact_small_strings): Tighten assertion a little.
19861 Replace pEd with more-general pI, and fix some printf arg casts.
19862 * lisp.h (pI): New macro, generalizing old pEd macro to other
19863 conversion specifiers. For example, use "...%"pI"d..." rather
19864 than "...%"pEd"...".
19865 (pEd): Remove. All uses replaced with similar uses of pI.
19866 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19867 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19868 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19869 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19870 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19871 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19872 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19874 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19875 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19876 * print.c (safe_debug_print, print_object): Likewise.
19877 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19879 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19880 avoiding the 0 flag, which is not portable.
19881 * process.c (Fmake_network_process): Use pI to avoid cast.
19882 * region-cache.c (pp_cache): Likewise.
19883 * xdisp.c (decode_mode_spec): Likewise.
19884 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19885 behavior on 64-bit hosts with printf arg.
19886 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19887 (x_stop_queuing_selection_requests): Likewise.
19888 (x_get_window_property): Don't truncate byte count to an 'int'
19891 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19892 here, since it parses constructs like leading '-' and spaces,
19893 which are not wanted; and it overflows with large numbers.
19894 Instead, simply match F[0-9]+, which is what is wanted anyway.
19896 * alloc.c: Remove unportable assumptions about struct layout.
19897 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19898 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19899 (allocate_vectorlike, make_pure_vector): Use the new macros,
19900 plus offsetof, to remove unportable assumptions about struct layout.
19901 These assumptions hold on all porting targets that I know of, but
19902 they are not guaranteed, they're easy to remove, and removing them
19903 makes further changes easier.
19905 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19906 This doesn't fix a bug but makes the code clearer.
19907 (string_overrun_cookie): Now const. Use initializers that
19908 don't formally overflow signed char, to avoid warnings.
19909 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19910 can cause Emacs to crash when string overrun checking is enabled.
19911 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19912 multiple of sizeof (EMACS_INT); it need not be, if
19913 alignof(EMACS_INT) < sizeof (EMACS_INT).
19914 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19916 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19918 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19920 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19922 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19923 supposed to be handshaking. (Bug#8556)
19924 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19926 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19928 * lisp.h (Qdebug): List symbol.
19929 * eval.c (Qdebug): Restore global linkage.
19930 * keyboard.c (debug-on-event): New variable.
19931 (handle_user_signal): Break into debugger when debug-on-event
19932 matches the current signal symbol.
19934 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19936 * alloc.c (check_sblock, check_string_bytes)
19937 (check_string_free_list): Convert to standard C.
19939 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19941 * w32.c (emacs_gnutls_push): Fix typo.
19943 2011-04-25 Eli Zaretskii <eliz@gnu.org>

20459 However, leave prepare_to_modify_buffer alone. It's never

20497 * xfaces.c (face_at_string_position):
20498 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

20667 Declare Lisp_Object Q* variables to be 'static' if not exported.
20668 This makes it easier for human readers (and static analyzers)
20669 to see whether these variables are used from other modules.

20683 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20685 Make Emacs functions such as Fatom 'static' by default.
20686 This makes it easier for human readers (and static analyzers)
20687 to see whether these functions can be called from other modules.
20688 DEFUN now defines a static function. To make the function external
20689 so that it can be used in other C modules, use the new macro DEFUE.

20695 Remove decls, since these functions are now static.
20696 (Funintern, Fget_internal_run_time): New decls, since these functions
20697 were already external.

20707 Mark functions with DEFUE instead of DEFUN,
20708 if they are used in other modules.
20709 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20710 decls for now-static functions.
20711 * buffer.h (Fdelete_overlay): Remove decl.

20747 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20749 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20750 when at ZV. (Bug#8487)
20752 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20754 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20763 (overrun_check_free): Protoize.
20765 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20767 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20768 since callers should never pass a negative size.
20769 Change the signature to match that of plain 'read' and 'write'; see
20770 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20771 * lisp.h: Update prototypes of emacs_write and emacs_read.
20773 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20775 * xdisp.c (redisplay_window): Don't try to determine the character
20776 position of the scroll margin if the window start point w->startp
20777 is outside the buffer's accessible region. (Bug#8468)
20779 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20781 Fix write-region and its subroutines for buffers > 2GB.
20782 * fileio.c (a_write, e_write): Modify declaration of arguments and
20783 local variables to support buffers larger than 2GB.
20784 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20786 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20787 argument, local variables, and return value.
20789 * lisp.h: Update prototypes of emacs_write and emacs_read.
20791 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20793 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20795 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20797 Fix more problems found by GCC 4.6.0's static checks.
20799 * xdisp.c (vmessage): Use a better test for character truncation.
20801 * charset.c (load_charset_map): <, not <=, for optimization,
20802 and to avoid potential problems with integer overflow.
20803 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20804 * casetab.c (set_identity, shuffle): Likewise.
20805 * editfns.c (Fformat): Likewise.
20806 * syntax.c (skip_chars): Likewise.
20808 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20809 This also lets GCC 4.6.0 generate slightly better loop code.
20811 * callint.c (Fcall_interactively): <, not <=, for optimization.
20812 (Fcall_interactively): Count the number of arguments produced,
20813 not the number of arguments given. This is simpler and lets GCC
20814 4.6.0 generate slightly better code.
20816 * ftfont.c: Distingish more carefully between FcChar8 and char.
20817 The previous code passed unsigned char * to a functions like
20818 strlen and xstrcasecmp that expect char *, which does not
20819 conform to the C standard.
20820 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20821 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20822 char * when the C standard requires it.
20824 * keyboard.c (read_char): Remove unused var.
20826 * eval.c: Port to Windows vsnprintf (Bug#8435).
20827 Include <limits.h>.
20828 (SIZE_MAX): Define if the headers do not.
20829 (verror): Do not give up if vsnprintf returns a negative count.
20830 Instead, grow the buffer. This ports to Windows vsnprintf, which
20831 does not conform to C99. Problem reported by Eli Zaretskii.
20832 Also, simplify the allocation scheme, by avoiding the need for
20833 calling realloc, and removing the ALLOCATED variable.
20835 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20837 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20838 But keep the doprint source code for now, as we might revamp it
20839 and use it again (Bug#8435).
20840 * lisp.h (doprnt): Remove.
20841 * Makefile.in (base_obj): Remove doprnt.o.
20842 * deps.mk (doprnt.o): Remove.
20844 error: Print 32- and 64-bit integers portably (Bug#8435).
20845 Without this change, on typical 64-bit hosts error ("...%d...", N)
20846 was used to print both 32- and 64-bit integers N, which relied on
20847 undefined behavior.
20848 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.

20853 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20854 Truncate the output at a character boundary, since vsnprintf does not
20856 * charset.c (check_iso_charset_parameter): Convert internal
20857 character to string before calling 'error', since %c now has the
20859 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20860 overflow when computing char to be passed to 'error'. Do not
20861 pass Lisp_Object to 'error'; pass the integer instead.
20862 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20863 formatted with plain %d.
20865 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.

20879 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20880 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20881 return ssize_t not "int", and use size_t as the buffer length.
20882 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20883 * gnutls.h: Update declarations.
20884 * process.c (read_process_output): Use ssize_t, to match.

20891 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20893 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20894 Use unsigned char, to match FcChar8 type definition.
20896 * xterm.c (handle_one_xevent):
20897 * xmenu.c (create_and_show_popup_menu):
20898 * xselect.c (x_decline_selection_request)
20899 (x_reply_selection_request): Avoid type-punned deref of X events.
20901 2011-04-09 Eli Zaretskii <eliz@gnu.org>

21000 This avoids several warnings with gcc -Wstrict-overflow.
21001 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21002 directly, rather than having caller test rule sign. This avoids
21003 some unnecessary tests.
21004 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21005 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21006 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21008 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21009 (xfont_open): Avoid unnecessary tests.
21011 * composite.c (composition_gstring_put_cache): Use unsigned integer.

21020 by using the new macro.
21022 * textprop.c (set_text_properties_1): Change while to do-while,
21023 since the condition is always true at first.
21025 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21026 (interval_deletion_adjustment): Return unsigned value.

21054 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21056 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21058 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21059 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21060 can always succeed if overflow has undefined behavior.
21062 * search.c (boyer_moore, wordify): Remove vars set but not used.
21063 (wordify): Omit three unnecessary tests.
21065 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21074 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21075 (Finsert_file_contents): Remove unnecessary code checking fd.
21077 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21078 Check for integer overflow on size calculations.
21080 * buffer.c (Fprevious_overlay_change): Remove var that is set
21083 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21084 Remove vars that are set but not used.
21085 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

21090 * image.c (lookup_image): Remove var that is set but not used.
21091 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21093 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21094 that are set but not used.
21096 * xfns.c (make_invisible_cursor): Don't return garbage
21097 if XCreateBitmapFromData fails (Bug#8410).
21099 * xselect.c (x_get_local_selection, x_handle_property_notify):
21100 Remove vars that are set but not used.
21102 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21103 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21105 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21106 Remove var that is set but not used.
21107 (scroll_bar_windows_size): Now size_t, not int.
21108 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21109 Check for overflow.

21120 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21121 (decode_coding_charset): Remove vars that are set but not used.
21123 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21124 that is set but not used.
21126 * print.c (print_object): Remove var that is set but not used.
21128 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21129 The gnulib version avoids calling malloc in the usual case,
21130 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21131 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21132 * filelock.c (current_lock_owner): Likewise.
21133 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21134 * sysdep.c: Include allocator.h, careadlinkat.h.
21135 (emacs_no_realloc_allocator): New static constant.
21136 (emacs_readlink): New function.
21137 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21138 ../lib/careadlinkat.h.
21140 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21142 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21143 first non-nil return value).

21158 and thereabouts. All callers changed.
21159 (get_per_char_metric): Remove parameter `f', unused since
21160 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21194 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21196 * keyboard.c (eval_dyn): New fun.
21197 (menu_item_eval_property): Use it.

21201 * fns.c (concat, mapcar1): Accept byte-code-functions.
21203 * eval.c (Fsetq): Handle lexical vars.
21204 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21205 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21206 (FletX, Flet): Obey lexical binding.
21207 (Fcommandp): Handle closures.
21208 (Feval): New `lexical' arg.
21209 (eval_sub): New function extracted from Feval. Use it almost
21210 everywhere where Feval was used. Look up vars in lexical env.
21212 (Ffunctionp): Move from subr.el.
21213 (Ffuncall): Handle closures.
21214 (apply_lambda): Remove `eval_flags'.
21215 (funcall_lambda): Handle closures and new byte-code-functions.
21216 (Fspecial_variable_p): New function.
21217 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21218 but without exporting it to Lisp.
21220 * doc.c (Fdocumentation, store_function_docstring):
21221 * data.c (Finteractive_form): Handle closures.
21223 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21226 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21228 (exec_byte_code): New function extracted from Fbyte_code to handle new
21229 calling convention for byte-code-functions. Add new byte-codes.
21231 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21233 * alloc.c (Fmake_symbol): Init new `declared_special' field.

21243 Limit scrolling to 100 screen lines.
21244 (redisplay_window): Even when falling back on "recentering",
21245 position point in the window according to scroll-conservatively,
21246 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21248 (try_scrolling): When point is above the window, allow searching
21249 as far as scroll_max, or one screenful, to compute vertical
21250 distance from PT to the scroll margin position. This prevents
21251 try_scrolling from unnecessarily failing when
21252 scroll-conservatively is set to a value slightly larger than the
21253 window height. Clean up the case of PT below the margin at bottom
21254 of window: scroll_max can no longer be INT_MAX. When aggressive
21255 scrolling is in use, don't let point enter the opposite scroll
21256 margin as result of the scroll.
21257 (syms_of_xdisp) <scroll-conservatively>: Document the
21258 threshold of 100 lines for never-recentering scrolling.

21266 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21267 (redisplay_internal): Remove parameter `preserve_echo_area',
21268 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21270 * indent.c (Fvertical_motion):
21271 * window.c (window_scroll_pixel_based, Frecenter):
21272 Don't pass `need_y_p' to `move_it_by_lines'.
21274 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21276 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21277 steal a few bits to be more compact.

21292 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21293 Remove unused local var.
21295 * editfns.c (Fmessage_box): Remove unused local var.
21297 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21298 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21299 Omit unused local vars.
21300 * window.c (shrink_windows): Omit unused local var.
21301 * menu.c (digest_single_submenu): Omit unused local var.
21302 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21303 Omit unused local var.
21305 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21306 Don't assume string length fits in int.
21307 (keyremap_step, read_key_sequence): Use size_t for sizes.
21308 (read_key_sequence): Don't check last_real_key_start redundantly.
21310 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21311 instead of alloca (Bug#8344).
21313 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21314 (Fbacktrace_frame): Don't assume nframes fits in int.
21316 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21318 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21321 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21323 * cm.c (calccost): Turn while-do into do-while, for clarity.
21325 * keyboard.c (syms_of_keyboard): Use the same style as later
21326 in this function when indexing through an array. This also
21327 works around GCC bug 48267.
21329 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21331 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

21334 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21336 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21337 This avoids undefined behavior on integer overflow, and is a bit
21338 more convenient anyway since it is compared to a size_t variable.
21340 Variadic C functions now count arguments with size_t, not int.
21341 This avoids an unnecessary limitation on 64-bit machines, which
21342 caused (substring ...) to crash on large vectors (Bug#8344).
21343 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21344 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21345 All variadic functions and their callers changed accordingly.

21350 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21351 (funcall_lambda, mark_backtrace): Likewise.
21352 * fns.c (concat): Likewise.
21353 * frame.c (x_set_frame_parameters): Likewise.
21354 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21355 0 if not found, not -1. All callers changed.
21357 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21358 (stack_copy_size): Now size_t, not int.
21359 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21368 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21369 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21379 * keyboard.c (safe_run_hook_funcall): New function.
21380 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21381 don't set the hook to nil, but remove the offending function instead.
21382 (Qcommand_hook_internal): Remove, unused.
21383 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21384 Vcommand_hook_internal.
21386 * eval.c (enum run_hooks_condition): Remove.
21387 (funcall_nil, funcall_not): New functions.
21388 (run_hook_with_args): Call each function through a `funcall' argument.

21398 * print.c (strout): Remove parameter `multibyte', unused since
21399 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21401 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21402 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

21415 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21416 All callers changed.
21418 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21420 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21449 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21451 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21453 * w32.c (read_unc_volume): Use parameter `henum', instead of
21454 global variable `wget_enum_handle'.
21456 * keymap.c (describe_vector): Remove parameters `indices' and

21474 * process.c (wait_reading_process_output):
21475 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.

21554 * term.c (Fsuspend_tty, Fresume_tty):
21555 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21556 * window.c (temp_output_buffer_show):

21563 * callint.c (Fcall_interactively):
21564 * buffer.c (Fkill_all_local_variables):
21565 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21567 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21568 unconditionally since it does the check itself.
21570 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21572 Fix more problems found by GCC 4.5.2's static checks.
21574 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21575 the first time through the loop, since we know p0 < p1 then.
21576 This also avoids a gcc -Wstrict-overflow warning.
21578 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21579 leading to a memory leak, possible in functions like
21580 load_charset_map_from_file that can allocate an unbounded number
21581 of objects (Bug#8318).
21583 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21584 that could (at least in theory) be that large.
21586 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21587 This is less likely to overflow, and avoids undefined behavior if
21588 overflow does occur. All callers changed. Use strtoul to scan
21589 for the unsigned long integer.
21590 (pint2hrstr): Simplify and tune code slightly.
21591 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21606 * process.c (Fmake_network_process): Use socklen_t, not int,
21607 where POSIX says socklen_t is required in portable programs.
21608 This fixes a porting bug on hosts like 64-bit HP-UX, where
21609 socklen_t is wider than int (Bug#8277).
21610 (Fmake_network_process, server_accept_connection):
21611 (wait_reading_process_output, read_process_output):
21614 * process.c: Rename or move locals to avoid shadowing.

21621 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21622 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21624 Make tparam.h and terminfo.c consistent.
21625 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21626 Include tparam.h instead, since it declares them.
21627 * cm.h (PC): Remove extern decl; tparam.h now does this.
21628 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21629 * terminfo.c: Include tparam.h, to check interfaces.
21630 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21631 (tparam): Adjust signature to match interface in tparam.h;
21632 this removes some undefined behavior. Check that outstring and len
21633 are zero, which they always are with Emacs.
21634 * tparam.h (PC, BC, UP): New extern decls.
21636 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21637 (xftfont_open): Rename locals to avoid shadowing.
21639 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21640 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

21643 (get_adstyle_property, ftfont_pattern_entity):
21644 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21645 Rename locals to avoid shadowing.
21647 * xfont.c (xfont_list_family): Mark var as initialized.
21649 * xml.c (make_dom): Now static.
21651 * composite.c (composition_compute_stop_pos): Rename local to
21653 (composition_reseat_it): Remove unused locals.
21654 (find_automatic_composition, composition_adjust_point): Likewise.
21655 (composition_update_it): Mark var as initialized.
21656 (find_automatic_composition): Mark vars as initialized,
21657 with a FIXME (Bug#8290).
21659 character.h: Rename locals to avoid shadowing.
21660 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21661 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21662 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21663 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21664 to avoid shadowing.
21666 * textprop.c (property_change_between_p): Remove; unused.
21668 * intervals.c (interval_start_pos): Now static.
21670 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21672 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21673 Rename locals to avoid shadowing.
21675 * sound.c (wav_play, au_play, Fplay_sound_internal):
21676 Fix pointer signedness.
21677 (alsa_choose_format): Remove unused local var.
21678 (wav_play): Initialize a variable to 0, to prevent undefined
21679 behavior (Bug#8278).
21681 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21683 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21685 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21686 clobbering (Bug#8298).
21687 * sysdep.c (sys_subshell): Likewise.
21688 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21690 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21691 This should get cleaned up, so that child_setup has the
21692 same signature on all platforms.
21694 * callproc.c (call_process_cleanup): Now static.
21695 (relocate_fd): Rename locals to avoid shadowing.
21697 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21699 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21700 not to be necessary, and produces flickering.
21702 2011-03-20 Glenn Morris <rgm@gnu.org>
21704 * config.in: Remove file.
21706 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21708 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21709 are now in src/globals.h.

21825 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21826 some of which prompt warnings from gcc -Wbad-function-cast.
21827 (Fformat_time_string, Fencode_time, Finsert_char):

21856 (Fmemory_limit): Cast sbrk's returned value to char *.
21858 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21861 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21863 Use functions, not macros, for up- and down-casing (Bug#8254).
21864 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21865 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21866 to use the following functions instead of these macros.
21867 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21868 EMACS_INT, since callers assume the returned value fits in int.
21869 (upcase1): Likewise, for UPCASE_TABLE.
21870 (uppercasep, lowercasep, upcase): New static inline functions.
21871 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21881 (regex_compile, re_match_2_internal): Mark locals as initialized.
21882 (RETALLOC_IF): Define only if needed.
21883 (WORDCHAR_P): Likewise. This one is never needed, but is used
21884 only in a comment talking about a compiler bug, so put inside
21885 the #if 0 of that comment.
21886 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21887 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21913 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21914 New macros, so that the caller can use some names other than
21915 gcpro1, gcpro2, etc.
21916 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21918 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21919 argument, for consistency with GCPRO2_VAR, etc: it is now the
21920 prefix of the variable, not the variable itself. All uses
21922 * dired.c (directory_files_internal, file_name_completion):
21923 Rename locals to avoid shadowing.
21925 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21926 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21927 dired.c's scmp function, had undefined behavior.
21928 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21929 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21930 * buffer.h: ... to here, because these macros use current_buffer,
21931 and the new implementation with inline functions needs to have
21932 current_buffer in scope now, rather than later when the macros
21934 (downcase, upcase1): New static inline functions.
21935 (DOWNCASE, UPCASE1): Reimplement using these functions.
21936 This avoids undefined behavior in expressions like
21937 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21938 from race conditions in accessing the global variables
21939 case_temp1 and case_temp2.
21940 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21941 * lisp.h (case_temp1, case_temp2): Remove their decls.
21942 * character.h (ASCII_CHAR_P): Move from here ...
21943 * lisp.h: ... to here, so that the inline functions mentioned
21944 above can use them.
21946 * dired.c (directory_files_internal_unwind): Now static.
21948 * fileio.c (file_name_as_directory, directory_file_name):
21949 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21951 (file_name_as_directory): Use const pointers when appropriate.
21952 (Fexpand_file_name): Likewise. In particular, newdir might
21953 point at constant storage, so make it a const pointer.
21954 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21955 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21957 (Fset_file_times, Finsert_file_contents, auto_save_error):

21962 to avoid shadowing.
21964 * marker.c (bytepos_to_charpos): Remove; unused.
21966 * lisp.h (verify_bytepos, count_markers): New decls,
21967 so that gcc does not warn that these functions aren't declared.
21969 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21970 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21971 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21972 (copy_text): Remove unused local var.
21974 * filelock.c (within_one_second): Now static.
21975 (lock_file_1): Rename local to avoid shadowing.
21977 * buffer.c (fix_overlays_before): Mark locals as initialized.
21978 (fix_start_end_in_overlays): Likewise. This function should be
21979 simplified by using pointers-to-pointers, but that's a different
21981 (switch_to_buffer_1): Now static.
21982 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21983 (report_overlay_modification): Rename locals to avoid shadowing.
21985 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21986 Fix pointer signedness issue.
21987 (sys_subshell): Mark local as volatile if checking for lint,
21988 to suppress a gcc -Wclobbered warning that does not seem to be right.
21989 (MAXPATHLEN): Define only if needed.
21991 * process.c (serial_open, serial_configure): Move decls from here ...
21992 * systty.h: ... to here, so that they can be checked.
21994 * fns.c (get_random, seed_random): Move extern decls from here ...
21995 * lisp.h: ... to here, so that they can be checked.
21997 * sysdep.c (reset_io): Now static.
21998 (wait_for_termination_signal): Remove; unused.
22000 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22001 (copy_keymap_item, append_key, push_text_char_description):
22003 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22004 (DENSE_TABLE_SIZE): Remove; unused.
22005 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22006 (describe_map_tree):
22007 Rename locals to avoid shadowing.
22009 * keyboard.c: Declare functions static if they are not used elsewhere.

22094 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22095 These macros can no longer be used for assignment.

22156 For example, without this patch (encode-time 0 0 0 1 1
22157 1152921504606846976) returns the obviously-bogus value (-948597
22158 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22159 reports time overflow. See
22160 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
22161 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
