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

309 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
311 * textprop.c: Use bool for booleans.
312 (validate_interval_range, Fadd_text_properties)
313 (Fremove_text_properties): Prefer bool to int when either works.
315 2013-03-02 Eli Zaretskii <eliz@gnu.org>
317 * textprop.c (Fadd_text_properties, Fremove_text_properties):
318 If the interval tree changes as a side effect of calling
319 modify_region, re-do processing starting from the call to
320 validate_interval_range. (Bug#13743)
322 2013-02-28 Eli Zaretskii <eliz@gnu.org>
324 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
327 2013-02-27 Eli Zaretskii <eliz@gnu.org>
329 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
330 _SH_DENYRW flag, instead of emacs_open, to deny any other process
331 access to the lock file until it is written and closed.
334 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
336 * callint.c (Qcall_interactively):
337 * macros.c (Qexecute_kbd_macro):
340 2013-02-26 Bastien Guerry <bzg@gnu.org>
342 * window.c (Frecenter): Tiny docstring enhancement.
344 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
346 Minor textprop integer cleanup.
347 * intervals.h, textprop.c (add_text_properties_from_list):
348 Return void, not int, since nobody uses the return value.
349 * textprop.c (validate_plist, add_properties, remove_properties)
350 (Fadd_text_properties):
351 Don't assume list length fits in int.
352 (interval_has_all_properties, interval_has_some_properties)
353 (interval_has_some_properties_list, add_properties, remove_properties)
354 (Fadd_text_properties, Fremove_text_properties)
355 (Fremove_list_of_text_properties, text_property_stickiness):
356 Use bool for booleans.

358 (Fremove_list_of_text_properties):
359 Reindent do-while as per GNU style.

363 Implement CLASH_DETECTION for MS-Windows.
365 * filelock.c [WINDOWSNT]: Include w32.h.
366 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
367 function of that name. Up-case the macro arguments.
368 (IS_LOCK_FILE): New macro.
369 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
370 (create_lock_file): New function, with body extracted from
372 [WINDOWSNT]: Implement lock files by writing a regular file with
373 the lock information as its contents.
374 (read_lock_data): New function, on Posix platforms just calls
376 [WINDOWSNT]: Read the lock info from the file.
377 (current_lock_owner): Call read_lock_data instead of calling
378 emacs_readlinkat directly.
379 (lock_file) [WINDOWSNT]: Run the file name through
382 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
383 just check if the process by that PID exists.
385 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
386 also present, as doing so will fail to error out if the file
389 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
391 * textprop.c (Fadd_text_properties, Fremove_text_properties)
392 (Fremove_list_of_text_properties): Skip all of the intervals in
393 the region between START and END that already have resp. don't
394 have the requested properties, not just the first one.

475 (syms_of_keyboard): Adjust accordingly.
477 2013-02-19 Daniel Colascione <dancol@dancol.org>
479 * sheap.c (report_sheap_usage): Use message, not message1, so
480 that we don't try to create a buffer while we're in the middle
481 of dumping Emacs. Explain why.
483 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
485 * search.c (find_newline): Return byte position in bytepos.
487 (find_next_newline_no_quit, find_before_next_newline):

495 (get_visually_first_element, move_it_vertically_backward):
496 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
498 2013-02-19 Eli Zaretskii <eliz@gnu.org>
500 * w32proc.c (new_child): Avoid leaking handles if the subprocess
501 resources were not orderly released.
503 2013-02-17 Eli Zaretskii <eliz@gnu.org>
505 * xdisp.c (x_draw_vertical_border): For a window that is neither
506 the leftmost nor the rightmost, redraw both the left and the right
507 vertical borders. (Bug#13723)

525 * frame.c (syms_of_frame): ... to here.
527 2013-02-16 Eli Zaretskii <eliz@gnu.org>
529 * w32.c (sys_chown): Remove unused function.
531 * w32term.c <input_signal_count>: Declare 'volatile'
532 unconditionally. (Bug#9066)
534 * w32.c (set_errno): Reset h_errno and don't set it to any other
535 value. Set errno instead.
536 (check_errno): Reset h_errno.

544 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
546 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
548 2013-02-15 Eli Zaretskii <eliz@gnu.org>
550 * keyboard.c (read_char): Fix calculation of auto-save time out
551 when auto-save-timeout is less than 4. (Bug#13720)
553 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

560 make sure errno is set to an appropriate value. (Bug#13546)
561 (socket_to_fd): Add assertion against indexing fd_info[] with a
562 value that is out of bounds.
563 (sys_accept): If fd is negative, do not set up the child_process
564 structure for reading.
566 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>

580 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
582 Fix AIX port (Bug#13650).
583 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
584 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
585 was #undeffed earlier, so it cannot be used as a macro here.
586 Use the constant and not the macro.
588 2013-02-15 Eli Zaretskii <eliz@gnu.org>
590 * w32proc.c (new_child): If no vacant slots are found in
591 child_procs[], make another pass looking for slots whose process
592 has exited or died. (Bug#13546)

595 MAXDESC, set errno to EMFILE.
596 (_sys_read_ahead): Update cp->status when failing to read serial
597 communications input, so that the status doesn't stay at
598 STATUS_READ_IN_PROGRESS. (Bug#13546)
600 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
602 * gtkutil.c (tb_size_cb): New function.

607 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
610 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
612 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
614 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
616 * font.c (font_range): Add pos_byte argument. Adjust comment
618 * font.h (font_range): Adjust prototype.
619 * composite.c (autocmp_chars): Pass byte position to font_range.

622 2013-02-13 Glenn Morris <rgm@gnu.org>
624 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
626 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
628 Improve AIX port some more (Bug#13650).
629 With this, it should be as good as it was in 23.3, though it's
630 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
631 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
632 * unexaix.c (start_of_text): Remove.
633 (_data, _text): Declare as char[], not int, as AIX manual suggests.
634 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
635 (orig_load_scnptr, orig_data_scnptr):
636 Now off_t, not long, since they are file offsets.
637 (make_hdr): Use _data, not start_of_data ().
638 This is the key part of the fix.
639 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
640 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
642 * pre-crt0.c (data_start): Initialize to 1.
643 This ports to compilers that optimize the external declaration
644 'int x = 0;' as if it were 'int x;' to shrink the executable.
646 Improve AIX port (Bug#13650).
647 This doesn't fix the bug, but it makes progress: Emacs builds now.
648 * unexaix.c: Include inttypes.h, stdarg.h.
649 (report_error, report_error_1): Mark as _Noreturn.
650 (report_error): Don't report the wrong errno.
651 (report_error_1): Now varargs. All callers changed.
652 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
653 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
654 (write_ptr): Use %p to print address rather than %lx and a cast
655 to unsigned long. Grow buffer a bit, to be safer.
657 2013-02-13 Eli Zaretskii <eliz@gnu.org>
659 * bidi.c (bidi_resolve_neutral): After finding the next
660 non-neutral character, accept NEUTRAL_ON type as well, because
661 directional control characters, such as LRE and RLE, have their
662 type converted to that by bidi_resolve_weak. This avoids aborts
663 when LRE/RLE follows a run of neutrals.
664 (bidi_move_to_visually_next): Assert that return value of
665 bidi_peek_at_next_level is non-negative. Negative values will
668 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
670 Minor getenv-related fixes.
671 * callproc.c (Fcall_process_region) [!DOS_NT]:
672 Avoid unnecessary duplicate call to getenv.
673 * callproc.c (init_callproc):
674 * dispnew.c (init_display):
675 * sysdep.c (sys_subshell):
676 Omit unnecessary cast of getenv or egetenv.
678 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
680 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
683 2013-02-12 Eli Zaretskii <eliz@gnu.org>
685 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
687 (display_line): Set w->region_showing to the value of
688 it->region_beg_charpos, not to -1. This fixes redisplay
689 optimization when cursor is moved up after M->. (Bug#13623)
691 (try_scrolling): Scroll text up more if point is too close to ZV
692 and inside the scroll margin. This makes sure point is moved
693 outside the scroll margin in these cases.
695 * window.h (struct window): region_showing can no longer be
698 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
700 Tune by using memchr and memrchr.
701 * doc.c (Fsnarf_documentation):
702 * fileio.c (Fsubstitute_in_file_name):
703 * search.c (find_newline, scan_newline):
704 * xdisp.c (pos_visible_p, display_count_lines):
705 Use memchr and memrchr rather than scanning byte-by-byte.
706 * search.c (find_newline): Rename from scan_buffer.
707 Omit first arg TARGET, as it's always '\n'. All callers changed.
709 Clean up read_key_sequence a tiny bit more.
710 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
711 (read_key_sequence): Remove unused locals.
713 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
715 Clean up read_key_sequence a bit; reread active keymaps after first event.
716 * keyboard.c (read_char, read_char_x_menu_prompt)
717 (read_char_minibuf_menu_prompt):
718 Replace nmaps+maps with a single `map' arg.
719 (follow_key): Operate on a single map.
720 (active_maps): New function.
721 (test_undefined): Also return true for nil bindings.
722 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
723 a single (composed) keymap. Remember `first_event' to choose the right
724 set of active keymaps. Recompute the set of keymaps after receiving
725 the first event. Remove GOBBLE_FIRST_EVENT.
726 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
727 * keyboard.h (read_char): Update declaration.
728 * lread.c (read_filtered_event): Adjust call to read_char.
730 2013-02-11 Eli Zaretskii <eliz@gnu.org>
732 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
733 Don't use the limitation on backwards movement when lines are truncated
734 in the window. (Bug#13675)
736 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
738 * marker.c (set_marker_internal): If desired position is passed
739 as a marker, avoid call to buf_charpos_to_bytepos.
740 * window.c (Fset_window_point): Omit redundant type checking.
741 (Fset_window_start): Likewise. Format comment.
742 (window_scroll_pixel_based): Use set_marker_restricted_both
743 with character and byte positions obtained from an iterator.
744 (Fset_window_configuration): Use set_marker_restricted_both.
745 * xdisp.c (message_dolog): Likewise.
747 2013-02-10 Eli Zaretskii <eliz@gnu.org>
749 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
750 When text lines are longer than window's screen lines, don't move back
751 too far. This speeds up some redisplay operations. (Bug#13675)
753 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
755 * syntax.c (scan_sexps_forward): Fix byte position calculation
756 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
758 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
760 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
763 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
765 Minor hashing refactoring.
766 * fns.c (SXHASH_REDUCE): Move to lisp.h.
767 (sxhash_float): Return EMACS_UINT, for consistency with the other
769 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
770 non-static inline function and therefore can't use static vars.
771 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
772 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
773 with the other hash functions.
775 2013-02-09 Eli Zaretskii <eliz@gnu.org>
777 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
778 XXXXXX part of the temporary file pattern is not downcased even
779 when w32-downcase-file-names is non-nil. (Bug#13661)
781 * xdisp.c (decode_mode_spec): Remove handling of %t.
783 * msdos.c (careadlinkatcwd): Remove.
785 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
787 * lread.c (skip_dyn_bytes): New function (bug#12598).
788 (read1): Use it. Use getc instead of READCHAR to read bytes.
789 (load_each_byte): Remove. Update users.
791 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
793 * search.c (scan_buffer): Calculate end byte position just once.
794 (scan_newline): Do not recalculate start_byte.
795 (search_command): Use eassert.
796 * syntax.c (struct lisp_parse_state): New member location_byte.
797 (scan_sexps_forward): Record from_byte and avoid redundant
798 character to byte position calculation ...
799 (Fparse_partial_sexp): ... here. Break too long line.
801 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
803 * lisp.h (make_uninit_vector): New function.
804 * alloc.c (Fvector, Fmake_byte_code):

816 * window.c (Fcurrent_window_configuration):
817 * xfaces.c (Fx_family_fonts):
818 * xselect.c (selection_data_to_lisp_data): Use it.
820 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
822 * coding.c (Fdefine_coding_system_internal): Use AREF where
823 argument is known to be a vector.
824 * fns.c (Flocale_info): Likewise for ASET.
825 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
826 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
828 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
830 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
833 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
834 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
835 updateCollectionBehaviour.
837 * nsterm.m (NEW_STYLE_FS): Remove.
838 (ns_last_use_native_fullscreen): New variable.
839 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
840 (x_set_window_size): Do not take title bar and tool bar into account
841 if isFullscreen returns YES.
842 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
843 (check_native_fs): New function.
844 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
845 (ns_term_init): Remove NEW_STYLE_FS.
846 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
847 and tool bar if isFullscreen returns NO.
848 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
849 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
851 (window:willUseFullScreenPresentationOptions:): New method.
852 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
853 Hide toolbar if not enabled (Bug#13444).
854 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
855 Restore tool bar if enabled, hide it otherwise (Bug#13444).
856 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
857 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
858 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
859 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
860 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
861 (syms_of_nsterm): Add ns-use-native-fullscreen.
863 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
865 * fileio.c (Qchoose_write_coding_system): Now static.
867 2013-02-04 Eli Zaretskii <eliz@gnu.org>
869 * xdisp.c (window_buffer_changed): region_showing can be negative,
870 which still means region is being displayed.
871 (redisplay_internal): Resurrect code that forced redisplay of the
872 whole window when showing region and the mark has changed.
873 Record the new mark position to allow redisplay optimizations.
874 (display_line): If it->region_beg_charpos is non-zero, set the
875 window's region_showing member to -1. (Bug#13623) (Bug#13626)
877 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
878 not bitfield of 1 bit.
880 2013-02-03 Daniel Colascione <dancol@dancol.org>
882 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
883 daemon mode works on cygw32 when Emacs is installed and not just
886 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
888 Avoid file time stamp bug on MS-Windows (Bug#13149).
889 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
890 as FAT32 doesn't update time stamps when truncating them.
891 Also, check that a file time stamp is not a multiple of 100 ns;
892 this should catch all instances of the problem on MS-Windows,
893 as its native file system resolution is 100 ns or worse, and
894 checking for a non-multiple of 100 ns should impose only a small
895 overhead on systems with ns resolution.
897 2013-02-02 Eli Zaretskii <eliz@gnu.org>
899 Avoid encoding file names on MS-Windows when they need to be run
900 through dostounix_filename.
901 * w32.c (normalize_filename): Accept an additional argument
902 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
903 downcase it even if w32-downcase-file-names is non-nil.
904 (dostounix_filename): Accept an additional argument MULTIBYTE and
905 pass it to normalize_filename.
906 (emacs_root_dir): Adjust.
908 * msdos.h (dostounix_filename): Adjust prototype.
910 * w32.h (dostounix_filename): Adjust prototype.
912 * msdos.c (dostounix_filename): Accept an additional argument and
914 (init_environment): Adjust callers of dostounix_filename.
916 * fileio.c (Ffile_name_directory, file_name_as_directory)
917 (directory_file_name, Fexpand_file_name)
918 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
920 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
922 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
923 variables, as egetenv is case-insensitive for DOS_NT.
925 * dired.c (file_name_completion): Don't call Fdirectory_file_name
926 with an encoded file name.
928 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
929 Adjust calls to dostounix_filename.
931 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
933 * unexw32.c (unexec): Adjust call to dostounix_filename.
935 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
937 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
940 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
943 * callproc.c (Fcall_process): Make sure program name in PATH and
944 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
945 is passed to exec/spawnve, which fails unless the file-name
948 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
949 even if w32-quote-process-args is nil.
951 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
953 Fix timestamp bug when write-region appends nothing (Bug#13149).
954 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
955 the file's time stamp doesn't change if Emacs happens to write nothing
956 to the file, and on a buggy file system this could cause Emacs to
957 incorrectly infer that the file system doesn't have the bug.
958 Avoid this problem by inhibiting the inference in this case.

966 * window.c (sequence_number): Remove.
967 (make_window): Initialize column_number_displayed.
968 * print.c (print_object): Follow the printed representation of
969 frames and print window pointer to distinguish between windows.

976 (display_mode_lines, decode_mode_spec): Adjust users.
977 * .gdbinit (pwinx): Do not print sequence_number.
979 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>

982 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
983 * dired.c: Include <fcntl.h>.
984 (open_directory): New function, which uses open and fdopendir
985 rather than opendir. DOS_NT platforms still use opendir, though.
986 (directory_files_internal, file_name_completion): Use it.
987 (file_attributes): New function, with most of the old Ffile_attributes.
988 (directory_files_internal, Ffile_attributes): Use it.
989 (file_attributes, file_name_completion_stat): First arg is now fd,
990 not dir name. All uses changed. Use fstatat rather than lstat +
992 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
993 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
994 (emacs_readlinkat): New function, with much of the old
995 Ffile_symlink_p, but with an fd argument for speed.
996 It uses readlinkat rather than careadlinkatcwd, so that it
997 need not assume the working directory.
998 (Ffile_symlink_p): Use it.
999 * filelock.c (current_lock_owner): Use emacs_readlinkat
1000 rather than emacs_readlink.
1001 * lisp.h (emacs_readlinkat): New decl.
1002 (READLINK_BUFSIZE, emacs_readlink): Remove.
1003 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.

1019 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1020 (sys_close): Zero out the flags for the file descriptor before
1021 closing it. (Bug#13546)
1023 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1024 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1025 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1028 * w32.c (w32_get_long_filename, init_environment, readlink):
1029 Support file names encoded in DBCS codepages.
1030 (readlink): Use the current file-name-coding-system, not the ANSI
1031 codepage, to decode and handle targets of symlinks.
1033 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1035 * w32.c (opendir): Now accepts a 'const char *'.
1037 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1039 Remove obsolete redisplay code. See the discussion at
1040 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1041 * dispnew.c (preemption_period, preemption_next_check): Remove.
1042 (Vredisplay_preemption_period): Likewise.
1043 (update_frame, update_single_window, update_window, update_frame_1):
1044 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1045 used, following the 2012-06-22 change.
1047 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1049 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1051 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1053 * font.c (num_fonts): Remove the leftover from old
1054 debugging code. Adjust comment style here and there.

1059 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1061 * w32.c (max_filename_mbslen): New function.
1062 (normalize_filename, readdir): Use it to detect locales where ANSI
1063 encoding of file names uses a double-byte character set (DBCS).
1064 If a DBCS encoding is used, advance by characters using
1065 CharNextExA, instead of incrementing a 'char *' pointer.
1066 Use _mbslwr instead of _strlwr. (Bug#13515)
1068 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1069 request of memory reservation to 1.7GB. (Bug#13065)
1071 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1073 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1074 at check_extra_latin label. (Bug#13505)
1076 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1078 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1079 Avoid redundant calls to strlen.
1081 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1083 Drop async_visible and async_iconified fields of struct frame.
1084 This is possible because async input is gone; for details, see
1085 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1086 * frame.h (struct frame): Remove async_visible and async_iconified
1087 members, convert garbaged to unsigned bitfield. Adjust comments.
1088 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1089 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1090 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1091 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1092 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1094 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1095 properly. Likewise for obscured.
1097 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1100 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1102 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1104 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1105 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1107 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1109 * xdisp.c (message2, message2_nolog): Remove functions.
1110 (message3, message3_nolog): Extract nbytes and multibyteness directly
1111 from the string. Change all callers.
1112 (message3_nolog): Don't set message_enable_multibyte since set_message
1113 will reset it anyway.
1114 (message1, message1_nolog): Use message3.
1115 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1116 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1117 (set_message): Drop all but the second arg, which has to be a string.
1118 (set_message_1): Simplify now that we know that a1 is NULL and the
1119 second arg is a string.
1120 * frame.h (struct frame): Remove `message_buf' field.
1121 Use glyphs_initialized_p instead.
1122 (FRAME_MESSAGE_BUF): Remove macro.

1131 * editfns.c (message_text, message_length): Remove vars.
1132 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1133 * fileio.c (auto_save_error): Use message3 instead of message2.
1134 * dispnew.c (adjust_frame_message_buffer): Remove function.
1136 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1138 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1139 real estate used for the tool bar and the menu bar.
1141 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1143 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1144 hidden buffer is prepared to modification (Bug#13164).
1146 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1148 * window.h (struct window): Change window_end_valid member from
1149 Lisp_Object to a bitfield. Adjust comments.
1150 (wset_window_end_valid): Remove.

1157 * xdisp.c (check_window_end, reconsider_clip_changes)
1158 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1159 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1160 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1162 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1164 * xdisp.c (mark_window_display_accurate): Simplify the loop
1165 assuming that the only one of vchild, hchild or buffer window
1166 slots is non-nil. Call mark_window_display_accurate_1 for
1167 the leaf windows only.
1168 (mark_window_display_accurate_1): Always assume leaf window.
1171 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1173 * emacs.c (Qkill_emacs_hook): Now static.
1175 * fileio.c (Finsert_file_contents): Simplify.
1176 Remove unnecessary assignments and tests.
1178 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1180 * w32.c (acl_set_file): Don't test for errors unless
1181 set_file_security returns FALSE. Avoids spurious errors when
1184 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1186 * fileio.c (Finsert_file_contents): Revert code introduced at
1187 2013-01-18 in favor of the simpler and generally better fix.
1188 Save stack space by removing 'buffer' and reusing 'read_buf'
1191 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1193 * lisp.h (eabs): Define unconditionally (Bug#13419).
1194 The old "#if !defined (eabs)" was an unnecessary revenant of back
1195 when this macro was called "abs". Document 'eabs' better.
1197 2013-01-19 Glenn Morris <rgm@gnu.org>
1199 * fns.c (Frandom): Doc fix.
1201 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1203 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1204 segfault when there are lots of overlays.
1206 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1207 when there are lots of overlays.
1208 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1209 for the details and a way to reproduce.
1211 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1213 * fileio.c: Use O_APPEND to append.
1214 This corresponds better to the natural interpretation of "append",
1215 and avoids the need to open the output file twice, or to invoke
1216 lseek when APPEND is neither nil nor a number.
1217 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1218 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1219 file possibly twice, and lseeking to its end; this avoids the
1220 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1221 at the same time: the combination is never needed and apparently
1222 it doesn't work with DOS_NT.
1224 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1225 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1227 Allow floating-point file offsets.
1228 Problem reported by Vitalie Spinu in
1229 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1230 * fileio.c (emacs_lseek): Remove.
1231 (file_offset): New function.
1232 (Finsert_file_contents, Fwrite_region): Use it.
1234 2013-01-19 Chong Yidong <cyd@gnu.org>
1236 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1237 aborting on Fsignal (Bug#13289).
1239 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1241 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1242 set_file_security as failure due to insufficient privileges.
1243 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1244 (fstat): Return owner and group like 'stat' and 'lstat' do.
1246 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1248 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1249 The bug was observed on Ubuntu operating inside a virtual machine,
1250 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1251 The workaround introduces a race condition on non-buggy hosts,
1252 but it's an unlikely race and anyway there's a nearly identical
1253 nearby race that can't be fixed.
1254 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1256 (Fwrite_region): Test for file system time stamp bug.
1257 (init_fileio): New function.
1258 * lisp.h (init_fileio): Declare it.
1259 * emacs.c (main): Call it.
1261 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1262 and make it more consistent with other stat-failure diagnostics.
1264 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1266 Fix crash when inserting data from non-regular files.
1267 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1268 for the error description produced by valgrind.
1269 * fileio.c (read_non_regular): Rename to read_contents.
1270 Free Lisp_Save_Value object used to pass parameters.
1271 (read_non_regular_quit): Rename to read_contents_quit.
1272 (Finsert_file_contents): Redesign internal file reading loop to adjust
1273 gap and end positions after each read and so help make_gap to work
1274 properly. Do not signal an I/O error too early and so do not leave
1275 not yet decoded characters in a buffer, which was the reason of
1276 redisplay crash. Use list2 to build return value. Adjust comments.
1278 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1280 Close a race when statting and reading files (Bug#13149).
1281 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1282 This avoids a race if the file is renamed between stat and open.
1283 This race is not the problem originally noted in Bug#13149;
1284 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1286 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1293 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1294 * alloc.c (format_save_value): Rename to make_save_value.
1295 (make_save_pointer): New function.
1296 (record_xmalloc): Use make_save_pointer.
1297 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1298 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:

1316 (map_keymap_char_table_item): Adjust accordingly.
1317 * fileio.c (non_regular_fd, non_regular_inserted)
1318 (non_regular_nbytes): Remove.
1319 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1320 Use format_save_value to pass parameters to read_non_regular.
1321 (read_non_regular): Use XSAVE_ macros to extract parameters.
1323 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1325 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1327 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1329 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1330 extraction from any Lisp_Save_Value slot. Add type checking.
1331 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1332 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1333 * xselect.c: All users changed.
1335 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1346 (save_excursion_restore): Use XSAVE_OBJECT.
1348 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1350 Avoid needless casts with XSAVE_POINTER.
1351 * alloc.c (mark_object) [GC_MARK_STACK]:
1352 * dired.c (directory_files_internal_unwind):
1353 * fileio.c (do_auto_save_unwind):
1354 * gtkutil.c (pop_down_dialog):
1355 * keymap.c (map_keymap_char_table_item):
1356 * lread.c (load_unwind):
1357 * nsmenu.m (pop_down_menu):
1358 * print.c (print_object) [GC_MARK_STACK]:
1359 * xfns.c (clean_up_file_dialog):
1360 * xmenu.c (cleanup_widget_value_tree):
1361 Omit casts between XSAVE_POINTER and a pointer type.
1363 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1365 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1366 * eval.c (eval_sub): Protect `form' from being GCed before its
1367 car and cdr becomes protected with the backtrace entry.
1369 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

1379 (free_misc): Likewise. Adjust comment.
1380 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1381 (free_save_value): Likewise.
1382 (mark_object): Likewise.
1383 * editfns.c (save_excursion_save): Pack everything within
1384 Lisp_Save_Value and so avoid xmalloc.
1385 (save_excursion_restore): Adjust to match new layout. Use free_misc
1386 because we do not allocate extra memory any more. Add eassert.
1387 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1388 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1402 Fix SIGDANGER handlers, for AIX (Bug#13408).
1403 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1428 (nsfont_list_family): Add block/unblock_input calls.
1429 (nsfont_open): Move block_input earlier. Add unblock_input before early
1431 (nsfont_draw): Add block/unblock_input calls.

1456 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1458 Avoid unnecessary byte position calculation for the gap movement.
1459 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1470 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1472 * term.c (init_tty): Use them instead of rolling our own code.
1473 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1474 switches from 'signal' to 'pthread_sigmask', which is safer in
1475 multithreaded applications.
1476 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1477 which has already arranged for that.
1478 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1479 This is the main part of the bug fix.

1493 * buffer.c (buffer_slot_type_mismatch): Remove.
1494 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1495 predicate. Adjust comment.

1499 right-fringe-width, scroll-bar-width and buffer-display-count.
1500 Use Qstringp for default-directory, buffer-file-name,
1501 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1502 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1504 * data.c (store_symval_forwarding): Adjust to call the predicate.

1520 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1521 (make_gap_1): New function to adjust the gap of any buffer.
1522 * coding.c (coding_alloc_by_making_gap): Use it.
1523 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1547 trailing dash is properly added.
1549 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1551 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1552 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1553 digits for buffer positions, before misalignment starts.
1554 Display "0" for integer "object" field.
1555 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1556 Display the newline glyph more unambiguously.
1558 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1560 * nsterm.m (ns_draw_underwave):
1561 * w32term.c (w32_draw_underwave):
1562 * xterm.c (x_draw_underwave): Make underwave look more triangular
1563 and also degrade gracefully for small fonts. (Bug#13000)
1565 * nsterm.m (ns_draw_text_decoration):
1566 * w32term.c (x_draw_glyph_string):
1567 * xterm.c (x_draw_glyph_string): Don't use previous underline
1568 thickness and position if previous underline type is underwave.
1570 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1572 * fileio.c (Ffile_acl): Undocument return format.
1574 2013-01-02 Glenn Morris <rgm@gnu.org>
1576 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

1588 * term.c (tty_ins_del_lines):
1589 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1590 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1592 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1594 * w32.c (unsetenv): Set up the string passed to _putenv
1596 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1597 for the bug this caused.
1599 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1601 * coding.c (Qmac): Now static.
1603 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1605 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1606 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1613 by TOOLBAR_TOP_WIDGET.
1614 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1615 Check toolbar_is_packed.
1616 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1618 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1620 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1621 (xg_update_menubar): Update title only if
1622 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1623 (xg_update_submenu): Skip tearoff only if
1624 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1625 (xg_initialize): Initialize xg_detached_menus only if
1626 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1628 * xterm.h (struct x_output): Surround handlebox_widget with
1629 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1630 toolbar_in_hbox is bool.
1632 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1634 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1635 (LIBS_GNUSTEP): Define.
1636 (LIBES): Add $(LIBS_GNUSTEP).

1639 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1641 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1642 continuation glyph on a TTY with an indication of an empty line.
1645 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1647 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1648 file's SELinux context or ACLs successfully set, nil otherwise.
1650 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

1653 SetEvent and WaitForSingleObject.
1655 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1657 Port EXTERNALLY_VISIBLE to Clang 3.2.
1658 * conf_post.h (__has_attribute): New macro.
1659 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1661 2012-12-27 Glenn Morris <rgm@gnu.org>
1663 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1664 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1666 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1668 * fileio.c (file_name_as_directory, directory_file_name):
1669 Accept an additional argument MULTIBYTE to indicate whether the input C
1670 came from a multibyte or a unibyte Lisp string; all callers
1671 adjusted. Don't assume the input string is always multibyte.
1673 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1674 don't ENCODE_FILE them, and return a unibyte string if the input
1676 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1677 don't assume the input strings will always be multibyte. If the
1678 input strings are multibyte, decode strings obtained from C
1681 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1683 * lisp.h (toplevel): Add two notices to the comment about
1684 defining a new Lisp data type.

1688 * alloc.c (valid_lisp_object_p): Adjust comment.
1690 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1692 * keyboard.c (record_asynch_buffer_change): Initialize an event
1693 only if it's really needed.
1694 * frame.h (enum output_method): Remove output_mac member since
1695 it's a leftover from the deleted code.
1696 * frame.c (Fframep): Adjust user here ...
1697 * terminal.c (Fterminal_live_p): ... and here.
1698 * coding.c (Qmac): Now here because it's only used to denote
1699 end-of-line encoding type.
1700 (syms_of_coding): DEFSYM it.
1701 * frame.h (Qmac): Remove duplicated declaration.
1703 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1705 * window.c (select_window_1): Now static, since it's used only here.
1707 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1709 * window.c (window_body_cols): Subtract display margins from the
1710 window body width on TTYs as well. See
1711 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1712 for the original report.
1714 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1716 * xdisp.c (redisplay_window): Remove inner local variable
1717 because the outer shadowed one has the same meaning.
1718 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1720 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1721 (xg_create_tool_bar): Adjust users.
1723 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1725 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1726 * buffer.c (Fget_buffer_create): Use it to set compact field of
1727 struct buffer_text to avoid accessing an uninitialized value
1728 when compact_buffer is called for the first time.
1729 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1730 (Fset_buffer_modified_p): Use buffer_window_count to check
1731 whether the buffer is displayed in some window.
1732 * xdisp.c (message_dolog): Likewise.
1734 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1736 * w32.c (acl_set_file): If setting the file security descriptor
1737 fails, and the new DACL is identical to the existing one, silently
1738 return success. This fixes problems for users backing up their
1739 own files without having the necessary privileges for setting
1740 security descriptors.
1742 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1744 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1745 after WaitForSingleObject returns normally. This expedites reader
1746 thread shutdown when delete_child triggers it.
1747 (reap_subprocess): More accurate commentary for why we call
1748 delete_child only when cp->fd is negative.
1750 * w32.c (sys_close): Do not call delete_child on a subprocess
1751 whose handle is not yet closed. Instead, set its file descriptor
1752 to a negative value, so that reap_subprocess will call
1753 delete_child on that subprocess when its SIGCHLD arrives.
1754 This avoids closing handles used for communications between sys_select
1755 and reader_thread, which doesn't give sys_select a chance to
1756 notice that the process exited and invoke the SIGCHLD handler for
1759 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1761 * nsfns.m (Fns_do_applescript): Run event loop until script has

1770 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1772 * w32term.c (w32fullscreen_hook): New function.
1773 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1775 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1777 * fileio.c (Finsert_file_contents): Doc fix.
1779 * w32proc.c (new_child, delete_child, find_child_pid): For a
1780 subprocess, consider its slot being in use as long as its process
1781 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1782 slot when a new process is started immediately after killing
1783 another one, without waiting enough time for the first process to
1784 be reaped and resources allocated for it be orderly freed.
1786 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1788 2012-12-21 Chong Yidong <cyd@gnu.org>
1790 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1792 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1794 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1796 * w32.c (get_name_and_id): Always pass NULL as the first argument
1797 of lookup_account_sid. Avoids crashes with UNC file names that
1798 refer to DFS domains, not to specific machine names. (Bug#12621)
1799 Remove now unused argument FNAME; all callers changed.
1800 (get_file_owner_and_group): Remove now unused argument FNAME; all
1803 2012-12-21 Chong Yidong <cyd@gnu.org>
1805 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1806 error for invalid chars, don't check for a nil return value.
1808 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1810 Avoid calls to CHAR_TO_BYTE if byte position is known.
1811 * editfns.c (make_buffer_string_both): Use move_gap_both.
1812 (Fbuffer_string): Use make_buffer_string_both.

1815 (buf_bytepos_to_charpos): Likewise.
1816 (charpos_to_bytepos): Remove.
1817 * fileio.c (Finsert_file_contents): Use move_gap_both.
1818 * search.c (Freplace_match): Likewise.
1819 * process.c (process_send_region): Likewise. Use convenient
1820 names for byte positions.
1821 * lisp.h (charpos_to_bytepos): Remove prototype.
1822 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1823 * insdel.c (move_gap): Likewise.

1831 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1832 (redisplay_internal): Don't bother selecting the frame to get the
1833 proper value of frame-local variables (bug#13225).
1835 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1837 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1838 Rename 4th argument since it may be buffer or string. Adjust comment.
1839 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1841 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1843 * coding.c (Fdetect_coding_region): Do not check start and end with
1844 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1845 (code_convert_region): Likewise.
1847 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1849 * w32.c (acl_get_file, acl_set_file): Run the file name through
1850 map_w32_filename, and resolve any symlinks in the file name, like
1852 (acl_set_file): Call revert_to_self, if any privileges were
1855 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1857 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1858 ($(BLD)/w32.$(O)): Update dependencies.
1860 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1862 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1863 propagate redisplay's scrolling (if any) to the right window.
1864 (redisplay_internal): Use ensure_selected_frame.
1865 (display_mode_lines): Complete last fix.
1866 * window.c (select_window_1): New func, extracted from select_window.
1867 (select_window): Use it.
1868 * window.h (select_window_1): Declare.
1870 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1872 Emulate Posix ACL APIs on MS-Windows.

1896 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1897 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1898 for some of that bug's symptoms can now cause Emacs to abort.
1899 Remove the workaround.
1900 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1901 The bug that caused SIGCHLD to get lost has been fixed, and the
1902 workaround for it can now cause Emacs to abort.
1904 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1906 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1952 delete the file, record it as pending deletion when the subprocess

1977 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1978 try to get accurate owner and group information from NT file
1979 security APIs. This is to make most callers of 'stat' and
1980 'lstat', which don't need that information, much faster.
1982 * dired.c (Ffile_attributes) [WINDOWSNT]:
1983 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1984 owner and group information from 'lstat'.

1988 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1989 as that confuses set-auto-coding, so insist on the head-read

2018 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2020 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2021 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2022 Remove unnecessary S_ISLNK test, as (contra the comments) this
2023 function can't copy symlinks. Improve quality of error message
2024 when attempting to copy files that are neither regular files nor

2107 (hinst): Remove unneeded extern declaration.
2108 (_start): Remove initialization of above variables; remove

2346 loop and return zero. (Bug#13086)
2348 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2350 * frame.h (x_char_width, x_char_height): Remove prototypes.
2351 * w32term.h (x_char_width, x_char_height): Likewise.
2352 * xfns.c (x_char_width, x_char_height): Remove.
2353 * w32fns.c (x_char_width, x_char_height): Likewise.
2354 * nsfns.c (x_char_width, x_char_height): Likewise.
2355 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
2357 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
2358 * keyboard.c (command_loop_1): Remove prototype.
2359 (command_loop_2, top_level_1): Add static to match prototype.
2361 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2363 Fix a recently-introduced delete-process race condition.
2364 * callproc.c, process.h (record_kill_process):
2365 New function, containing part of the old call_process_kill.
2366 (call_process_kill): Use it.
2367 This does not change call_process_kill's behavior.
2368 * process.c (Fdelete_process): Use record_kill_process to fix a
2369 race condition that could cause Emacs to lose track of a child.
2371 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2373 Avoid code duplication between prev_frame and next_frame.
2374 * frame.c (candidate_frame): New function. Add comment.
2375 (prev_frame, next_frame): Use it. Adjust comment.
2377 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2379 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2380 fails, signal an error instead of continuing with an empty
2382 Encode expanded temp file pattern before passing it to mkstemp or
2385 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2386 Encode the file name before passing it to dostounix_filename, in
2387 case it will downcase it (under w32-downcase-file-names).
2390 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2392 Minor call-process cleanups.
2393 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2394 at the same time as other platforms, to simplify analysis.
2395 No need for fd0_volatile since we have synch_process_fd.
2396 Avoid needless emacs_close; arg is always negative.
2398 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2400 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2403 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2405 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2406 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2407 and mouse_face_hidden members to a bitfields.
2408 * frame.h (struct frame): Remove set-but-not-used space_width member.
2409 (FRAME_SPACE_WIDTH): Remove.
2410 * nsterm.m, w32term.c, xterm.c: Adjust users.
2411 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2412 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2413 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2414 members to a bitfields.
2416 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2418 Don't let call-process be a zombie factory (Bug#12980).
2419 Fixing this bug required some cleanup of the signal-handling code.
2420 As a side effect, this change also fixes a longstanding rare race
2421 condition whereby Emacs could mistakenly kill unrelated processes,
2422 and it fixes a bug where a second C-g does not kill a recalcitrant
2423 synchronous process in GNU/Linux and similar platforms.
2424 The patch should also fix the last vestiges of Bug#9488,
2425 a bug which has mostly been fixed on the trunk by other changes.
2426 * callproc.c, process.h (synch_process_alive, synch_process_death)
2427 (synch_process_termsig, sync_process_retcode):
2428 Remove. All uses removed, to simplify analysis and so that
2429 less consing is done inside critical sections.
2430 * callproc.c (call_process_exited): Remove. All uses replaced
2431 with !synch_process_pid.
2432 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2433 These take the role of what used to be in unwind-protect arg.
2435 (block_child_signal, unblock_child_signal):
2436 New functions, to avoid races that could kill innocent-victim processes.
2437 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2438 (call_process_kill): Record killed processes as deleted, so that
2439 zombies do not clutter up the system. Do this inside a critical
2440 section, to avoid a race that would allow the clutter.
2441 (call_process_cleanup): Fix code so that the second C-g works again
2442 on common platforms such as GNU/Linux.
2443 (Fcall_process): Create the child process in a critical section,
2444 to fix a race condition. If creating an asynchronous process,
2445 record it as deleted so that zombies do not clutter up the system.
2446 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2447 light of these changes. Omit unnecessary call to emacs_close
2448 before failure, as the unwind-protect code does that.
2449 * callproc.c (call_process_cleanup):
2450 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2451 * process.c (record_deleted_pid): New function, containing
2452 code refactored out of Fdelete_process.
2453 (Fdelete_process): Use it.
2454 (process_status_retrieved): Remove. All callers changed to use
2455 child_status_change.
2456 (record_child_status_change): Remove, folding its contents into ...
2457 (handle_child_signal): ... this signal handler. Now, this
2458 function is purely a handler for SIGCHLD, and is not called after
2459 a synchronous waitpid returns; the synchronous code is moved to
2460 wait_for_termination. There is no need to worry about reaping
2461 more than one child now.
2462 * sysdep.c (get_child_status, child_status_changed): New functions.
2463 (wait_for_termination): Now takes int * status and bool
2464 interruptible arguments, too. Do not record child status change;
2465 that's now the caller's responsibility. All callers changed.
2466 Reimplement in terms of get_child_status.
2467 (wait_for_termination_1, interruptible_wait_for_termination):
2468 Remove. All callers changed to use wait_for_termination.
2469 * syswait.h: Include <stdbool.h>, for bool.
2470 (record_child_status_change, interruptible_wait_for_termination):
2472 (record_deleted_pid, child_status_changed): New decls.
2473 (wait_for_termination): Adjust to API changes noted above.
2475 * bytecode.c, lisp.h (Qbytecode): Remove.
2476 No longer needed after 2012-11-20 interactive-p changes.
2478 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2480 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2481 the scroll margin, move point outside the margin. (Bug#13055)
2483 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2485 * gtkutil.c (my_log_handler): New function.
2486 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2488 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2490 * lisp.h (modify_region): Rename to...
2491 (modify_region_1): ...new prototype.
2492 * textprop.c (modify_region): Now static. Adjust users.
2493 * insdel.c (modify_region): Rename to...
2494 (modify_region_1): ...new function to work with current buffer.
2495 Adjust comment and users. Use true and false for booleans.
2497 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2499 * alloc.c (free_save_value): New function.
2500 (safe_alloca_unwind): Use it.
2501 * lisp.h (free_save_value): New prototype.
2502 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2504 (save_excursion_restore): Adjust to match saved data structure.
2505 Use free_save_value to offload some work from GC. Drop obsolete
2508 2012-12-03 Chong Yidong <cyd@gnu.org>
2510 * fileio.c (Vauto_save_list_file_name): Doc fix.
2512 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2514 * w32fns.c: Remove prototype of atof.
2515 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2517 (file_dialog_callback): Make it UINT_PTR.
2519 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2522 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2523 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2526 2012-12-03 Glenn Morris <rgm@gnu.org>
2528 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2530 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2532 Fix xpalloc confusion after memory is exhausted.
2533 * alloc.c (xpalloc): Comment fix.
2534 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2535 and signals an error, do not clear charset_table_size, as
2536 charset_table is still valid.
2537 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2539 Use execve to avoid need to munge environ (Bug#13054).
2540 * callproc.c (Fcall_process):
2541 * process.c (create_process):
2542 Don't save and restore environ; no longer needed.
2543 * callproc.c (child_setup):
2544 Use execve, not execvp, to preserve environ.
2546 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2548 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2550 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2552 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2553 display for sliced images (Bug#10500).
2555 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2557 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2559 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2560 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2562 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2564 * xdisp.c (window_outdated): Remove eassert since it hits
2565 some suspicious corner cases (see Bug#13007 and Bug#13012).
2566 (mode_line_update_needed): New function.
2567 (redisplay_internal, redisplay_window): Use it.
2568 (ensure_selected_frame): New function.
2569 (redisplay_internal, unwind_redisplay): Use it.
2570 (redisplay_internal): Move comment about buffer_shared...
2571 (buffer_shared_and_changed): ...near to its real use.
2573 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2575 * callproc.c (Fcall_process): Don't misreport vfork failure.
2577 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2579 * callproc.c (Fcall_process): Fix vfork portability problems.
2580 Do not assume that fd[0], count, filefd, and save_environ survive
2581 vfork. Fix bug whereby wrong errno value could be reported for
2582 pipe failure. Some minor cleanups, too, as follows. Move buf and
2583 bufsize to the context where they're needed. Change new_argv to
2584 be of type char **, as this is more convenient and avoids casts.
2585 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2586 Now local constants, not macros.
2588 2012-11-18 Kenichi Handa <handa@gnu.org>
2590 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2591 for the variable "f".
2593 2012-11-13 Kenichi Handa <handa@gnu.org>
2595 * font.c (font_unparse_xlfd): Exclude special characters from the
2596 generating XLFD name.
2598 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2602 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2604 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2623 violations when repeatedly clicking on the "Top" link of the
2624 "bread-crumbs" in Info buffers.

2638 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2639 between bpos_covered and bpos_max. This fixes cursor display when
2640 several display strings follow each other.
2642 * .gdbinit (pgx): If the glyph's object is a string, display the
2643 pointer to string data, rather than the value of the string object
2644 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2646 * indent.c (Fvertical_motion): If the starting position is covered
2647 by a display string, return to one position before that, to avoid
2648 overshooting it inside move_it_to. (Bug#12930)
2650 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2660 asked_for_visible and menubar_active members.
2661 Drop unused pending_menu_activation member.
2662 * xterm.h (struct x_output): Drop outdated #if 0 code.
2663 Use bitfields for explicit_parent, asked_for_visible,
2664 has_been_visible and net_wm_state_hidden_seen members.

2669 of a literal "/". (Bug#12955)
2670 (gl-stamp): Invoke fc.exe directly, not through cmd.

2675 * dired.c: Assume HAVE_DIRENT_H.
2676 (NAMLEN): Remove, replacing with ...
2677 (dirent_namelen): New function. All uses changed. Use the GNU macro
2678 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2679 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2680 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2681 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2683 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2684 * ndir.h: Rename to ../nt/inc/dirent.h.
2685 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2686 Do not include <dirent.h>; no longer needed.
2687 * w32.c: Include <dirent.h> rather than "ndir.h".
2689 2012-11-23 Chong Yidong <cyd@gnu.org>
2691 * xftfont.c (xftfont_open): Remove duplicate assignment.
2693 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2695 * alloc.c (Fgarbage_collect): Unblock input after clearing
2696 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2697 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2698 * msdos.c (IT_frame_up_to_date): Use it here...
2699 * w32term.c (w32_frame_up_to_date): ...here...
2700 * xterm.c (XTframe_up_to_date): ...and here...
2701 * nsterm.m (ns_frame_up_to_date): ...but not here.
2702 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2704 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2705 Do not check whether GC is in progress.

2709 * xdisp.c (window_buffer_changed): New function.
2710 (update_menu_bar, update_tool_bar): Use it to
2711 simplify large 'if' statements.

2713 'tail' and 'frame' local variables.
2715 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2717 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2718 with Windows system header.

2739 * emacs.c (main): Set the G_SLICE environment variable for all
2740 Cygwin builds, not just GTK builds. See
2741 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2743 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2745 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2746 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2747 Define for the MSVC compiler.
2749 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2751 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2752 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to

2754 dostounix_filename assumes it gets a unibyte string.
2755 Reported by Michel de Ruiter <michel@sentient.nl>, see

2794 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2795 cygwin_convert_file_name*.

2802 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2804 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2806 * w32select.c: Include w32common.h before w32term.h, so that
2807 windows.h gets included before w32term.h uses some of its
2808 features, see below.
2810 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2812 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2814 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2816 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2818 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2819 (ns_select): Return at once if events are held (Bug#12834).
2821 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2823 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2824 Needed following 2012-10-20 change. (Bug#12902)
2826 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2828 * w32proc.c (waitpid): Remove unused label get_result.
2830 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2832 * makefile.w32-in (SYSWAIT_H): New macro.
2833 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2834 ($(BLD)/sysdep.$(O)): Update dependencies.
2836 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2838 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2839 * callproc.c (relocate_fd): Assume F_DUPFD.
2840 * emacs.c, term.c (O_RDWR): Remove.
2841 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2842 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2843 * nsterm.m: Assume <fcntl.h> exists.
2844 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2845 (create_pty, Fmake_network_process, server_accept_connection)
2846 (wait_reading_process_output, init_process_emacs):
2848 (wait_reading_process_output): Put in a special case for WINDOWSNT
2849 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2850 It's not clear this is needed, but it's a more-conservative change.
2851 (create_process): Assume FD_CLOEXEC.
2852 (create_process, create_pty): Assume O_NOCTTY.
2853 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2854 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2855 Omit if not DOS_NT, since F_GETFL is not defined there.
2856 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2857 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2859 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2860 lack it, since gnulib guarantees this.
2861 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2863 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2865 * w32.c (faccessat): Pretend that directories have the execute bit
2866 set. Emacs expects that, e.g., in files.el:cd-absolute.
2868 * w32proc.c (create_child): Don't clip the PID of the child
2869 process to fit into an Emacs integer, as this is no longer a
2871 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2872 reaping only the process specified by PID argument, if that is
2873 positive. Use PID instead of dead_child to know which process to
2874 reap. Wait for the child to die only if WNOHANG is not in
2876 (sys_select): Don't set dead_child.
2878 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2879 as it is no longer needed.
2881 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2883 (record_child_status_change): Remove the setting of
2884 record_at_most_one_child for the !WNOHANG case.
2886 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2888 Fix problems in ns port found by static checking.
2889 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2890 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2891 not to process group.
2892 (ns_select): Use emacs_write, not write, as that's more robust
2893 in the presence of signals.
2894 (fd_handler:): Check for read errors.
2896 2012-11-16 Glenn Morris <rgm@gnu.org>
2898 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2900 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2902 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2904 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2906 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2907 use the same value of thread handle.
2908 (start_timer_thread): If the timer thread exited (due to error),
2909 clean up by closing the two handles it used. Duplicate the caller
2910 thread's handle here, so it gets duplicated only once, when
2911 launching the timer thread. Set priority of the timer thread, not
2913 (getitimer): Don't duplicate the caller thread's handle here.
2916 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2918 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2921 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2923 Remove no-longer-used pty_max_bytes variable.
2924 * process.c (pty_max_bytes): Remove; unused.
2925 (send_process): Do not set it.
2927 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2929 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2930 Update dependencies.
2932 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2934 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2935 This follows up on the 2012-09-29 patch that removed indirection
2936 for the 'function' field. Reported by Sergey Vinokurov in
2937 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2939 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2941 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2942 different name, as the MS runtime does not have such a function,
2943 and probably never will.) All callers changed. Ignore DIRFD
2944 value if PATH is an absolute file name, to match Posix spec
2945 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2948 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2950 * xdisp.c (echo_area_display, redisplay_internal):
2951 Omit redundant check whether frame_garbaged is set.
2953 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2955 Use faccessat, not access, when checking file permissions (Bug#12632).
2956 This fixes a bug that has been present in Emacs since its creation.
2957 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2958 which must set some sort of record. (Torek's bug report was against
2959 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2960 same common flaw.) See Torek's Usenet posting
2961 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2962 Posted: Fri Apr 8 14:18:56 1983.
2963 * Makefile.in (LIB_EACCESS): New macro.
2965 * callproc.c (init_callproc):
2966 * charset.c (init_charset):
2967 * fileio.c (check_existing, check_executable, check_writable)
2969 * lread.c (openp, load_path_check):
2970 * process.c (allocate_pty):
2972 Use effective UID when checking permissions, not real UID.
2973 * callproc.c (init_callproc):
2974 * charset.c (init_charset):
2975 * lread.c (load_path_check, init_lread):
2976 Test whether directories are accessible, not merely whether they exist.
2977 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2978 * fileio.c (check_existing, check_executable, check_writable)
2980 Use symbolic names instead of integers for the flags, as they're
2982 (check_writable): New arg AMODE. All uses changed.
2983 Set errno on failure.
2984 (Ffile_readable_p): Use faccessat, not stat + open + close.
2985 (Ffile_writable_p): No need to call check_existing + check_writable.
2986 Just call check_writable and then look at errno. This saves a syscall.
2987 dir should never be nil; replace an unnecessary runtime check
2988 with an eassert. When checking the parent directory of a nonexistent
2989 file, check that the directory is searchable as well as writable, as
2990 we can't create files in unsearchable directories.
2991 (file_directory_p): New function, which uses 'stat' on most platforms
2992 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2993 (Ffile_directory_p, Fset_file_times): Use it.
2994 (file_accessible_directory_p): New function, which uses a single
2995 syscall for efficiency.
2996 (Ffile_accessible_directory_p): Use it.
2997 * xrdb.c (file_p): Use file_directory_p.
2998 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2999 * lread.c (openp): When opening a file, use fstat rather than
3000 stat, as that avoids a permissions race. When not opening a file,
3001 use file_directory_p rather than stat.
3002 (dir_warning): First arg is now a usage string, not a format.
3003 Use errno. All uses changed.
3004 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3005 that merely introduced a race.
3006 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3007 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3008 and similarly for the other O_* flags.
3009 * w32.c (sys_faccessat): Rename from sys_access and switch to
3010 faccessat's API. All uses changed.
3011 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3012 (magic_db): Rename from magic_file_p.
3013 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3014 char *, so that we don't have to test for file existence
3015 separately from opening the file for reading. This removes a race
3016 fixes a permission-checking problem, and simplifies the code.
3018 (file_p): Remove; no longer needed.
3020 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3022 Omit glyphs initialization at startup.
3023 * dispnew.c (glyphs_initialized_initially_p): Remove.
3024 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3025 (Fredraw_frame): Move actual code from here...
3026 (redraw_frame): ...to here. Add eassert. Adjust comment.
3027 (Fredraw_display): Use redraw_frame.
3028 * xdisp.c (clear_garbaged_frames): Likewise.
3030 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3032 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3033 passed to pint2str and pint2hrstr to be at most the size of the
3034 frame's decode_mode_spec_buffer. This avoids crashes with very
3035 large values of FIELD_WIDTH argument to decode_mode_spec.
3038 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3040 Fix a race with verify-visited-file-modtime (Bug#12863).
3041 Since at least 1991 Emacs has ignored an mtime difference of no
3042 more than one second, but my guess is that this was to work around
3043 file system bugs that were fixed long ago. Since the race is
3044 causing problems now, let's remove that code.
3045 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3046 whose time stamp is off by no more than a second. Insist that the
3047 file time stamps match exactly.
3049 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3051 * frame.h (struct frame): Convert external_tool_bar member to
3052 1-bit unsigned bitfield.
3053 * termhooks.h (struct terminal): Remove mouse_moved member since
3054 all users are long dead. Adjust comment on mouse_position_hook.
3056 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3058 Simplify by using FOR_EACH_FRAME here and there.
3059 * frame.c (next_frame, prev_frame, other_visible_frames)
3060 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3061 * w32term.c (x_window_to_scroll_bar): Likewise.
3062 * window.c (window_list): Likewise.
3063 * xdisp.c (x_consider_frame_title): Likewise.
3064 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3065 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3066 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3067 * xmenu.c (menubar_id_to_frame): Likewise.
3068 * xselect.c (frame_for_x_selection): Likewise.
3069 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3070 (x_window_to_menu_bar): Likewise.
3071 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3073 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3075 * data.c (Qdefalias_fset_function): Now static.
3077 Another tweak to vectorlike_header change.
3078 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3079 Remove, and replace all uses with ...
3080 (next_in_free_list, set_next_in_free_list):
3081 New functions, which respect C's aliasing rules better.
3083 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3085 * window.c (list4i): Rename from 'quad'. All uses changed.
3086 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3088 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3090 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3091 warning about mixing declarations and code in ISO C90.
3093 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3095 * window.c (Fsplit_window_internal): Set combination limit of
3096 new parent window to t iff Vwindow_combination_limit is t;
3097 fixing a regression introduced with the change from 2012-09-22.
3098 (Fset_window_combination_limit): Fix doc-string.
3100 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3102 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3103 amount when the scroll margins are too large. When scrolling
3104 backwards in the buffer, give up if cannot reach point or the
3105 scroll margin within a reasonable number of screen lines.
3106 Fixes point position in window under scroll-up/down-aggressively when
3107 point is positioned many lines beyond the window top/bottom.
3110 * ralloc.c (relinquish): If real_morecore fails to return memory
3111 to the system, don't crash; instead, leave the last heap
3112 unchanged and return. (Bug#12774)
3114 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3116 * lisp.h (AUTOLOADP): New macro.
3117 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3118 * data.c (Ffset): Remove special ad-advice-info handling.
3119 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3121 (Finteractive_form): Simplify.
3122 (Fquo): Don't insist on having at least 2 arguments.
3123 (Qdefalias_fset_function): New var.
3125 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3127 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3131 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3133 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3135 Fix recently introduced crash on MS-Windows (Bug#12839).
3136 * w32term.h (struct scroll_bar): Use convenient header.
3137 (SCROLL_BAR_VEC_SIZE): Remove.
3138 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3140 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3142 Tweak last vectorlike_header change.
3143 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3144 vectorlike object on the free list. This is introduced to avoid
3145 some (but not all) pointer casting and aliasing problems, see
3146 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3147 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3149 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3151 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3153 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3154 been removed, so remove them here also.
3156 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3158 * doc.c (Fdocumentation): Handle new property
3159 dynamic-docstring-function to replace the old ad-advice-info.
3161 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3163 * fns.c (Qeql, hashtest_eq): Now static.
3165 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3167 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3168 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3169 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3170 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3172 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3174 Use same hash function for hashfn_profiler as for hash_string etc.
3175 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3176 * lisp.h (sxhash_combine): New inline function, with the contents
3177 of the old SXHASH_COMBINE.
3178 * profiler.c (hashfn_profiler): Use it, instead of having a
3179 special hash function containing a comparison that always yields 1.
3181 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3183 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3184 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3185 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3188 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3190 * image.c (xpm_make_color_table_h): Fix compiler error because
3191 make_hash_table changed.
3193 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3195 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3197 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3199 Use ad-hoc comparison function for the profiler's hash-tables.
3200 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3201 (make_log): Use them.
3202 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3203 call Fequal any more.
3204 (Ffunction_equal): New function.

3212 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3213 (hash_lookup, hash_remove_from_table): Move assertion checking of
3214 hashfn result here. Check hash-equality before calling cmpfn.
3215 (Fmake_hash_table): Adjust call to make_hash_table.
3216 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3217 (syms_of_fns): Initialize them.

3221 * print.c (print_object): Adjust to new hash-table struct.
3222 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
3224 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3226 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3227 value of w32-scroll-lock-modifier is neither nil nor one of the
3228 known key modifiers. (Bug#12806)
3230 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3232 Shrink struct vectorlike_header to the only size field.
3233 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3235 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3236 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3237 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3238 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3239 information from the vector header. Adjust comment.
3240 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)

3248 (sweep_string, lisp_malloc): Remove useless prototypes.
3249 (enum mem_type): Adjust comment.
3250 (NEXT_IN_FREE_LIST): New macro.
3251 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3252 (Fmake_bool_vector): Likewise.
3253 (struct large_vector): New type to represent allocation unit for
3254 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3255 (large_vectors): Change type to struct large_vector.
3256 (allocate_vector_from_block): Simplify.
3257 (PSEUDOVECTOR_NBYTES): Replace with...
3258 (vector_nbytes): ...new function. Adjust users.
3259 (sweep_vectors): Adjust processing of large vectors.
3260 (allocate_vectorlike): Likewise.
3261 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3262 Add easserts. Adjust XSETPVECTYPESIZE usage.
3263 (allocate_buffer): Use BUFFER_PVEC_INIT.
3264 (live_vector_p): Adjust to match large vector.
3265 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3266 * buffer.h (struct buffer): Add next member.
3267 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3269 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3270 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3271 (copy_hash_table): Adjust to match vector header change.
3272 * lread.c (defsubr): Use XSETPVECTYPE.
3273 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3274 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3275 (xvecsize): New command.
3277 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3279 * keyboard.c (event_to_kboard): Do not dereference
3280 frame_or_window field of SELECTION_REQUEST_EVENT
3281 and SELECTION_CLEAR_EVENT events (Bug#12814).
3282 * xterm.h (struct selection_input_event): Adjust comment.
3284 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3286 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3287 such as Scroll Lock, if the respective keys are treated as
3288 function keys, not as modifiers. This avoids destroying non-ASCII
3289 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3291 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3293 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3295 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3297 Restore some duplicate definitions (Bug#12814).
3298 This undoes part of the 2012-11-03 changes. Some people build
3299 with plain -g rather than with -g3, and they need the duplicate
3300 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3301 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3302 Define as macros, as well as as enums or as constants.
3304 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3306 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3307 to keypad keys (Bug#12816).
3309 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3311 Minor adjustments of recently-changed frame functions.
3312 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3313 known to be a frame (we're in the FRAMEP branch).
3314 * lisp.h (Qframep): Remove decl. frame.h declares this.
3315 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3316 since they're meant for Lisp fixnum values.
3318 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3320 * window.c (Fwindow_combination_limit): Revert to the only
3321 required argument and adjust docstring as suggested in
3322 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3323 by Martin Rudalics <rudalics@gmx.at>.
3325 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3327 Widely used frame validity and checking functions.
3328 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3329 * frame.c (decode_live_frame, decode_any_frame): New functions.
3330 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3331 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3332 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3333 (Fframe_pointer_visible_p): Use decode_any_frame.
3334 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3335 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3336 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3337 (Fframe_focus): Likewise. Allow zero number of arguments.
3339 (frame_buffer_list, frame_buffer_predicate): Remove.
3340 * lisp.h (frame_buffer_predicate): Remove prototype.
3341 * buffer.c (Fother_buffer): Use decode_any_frame.
3342 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3343 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3344 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3345 (Fclose_font, Ffont_info): Use decode_live_frame.
3346 * fontset.c (check_fontset_name): Likewise.
3347 * terminal.c (Fframe_terminal): Likewise.
3348 * w32fns.c (check_x_frame): Likewise.
3349 * window.c (Fminibuffer_window, Fwindow_at)
3350 (Fcurrent_window_configuration): Likewise.
3351 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3352 Likewise. Allow zero number of arguments. Adjust docstring.
3353 * dispnew.c (Fredraw_frame): Likewise.
3354 * xfaces.c (frame_or_selected_frame): Remove.
3355 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3356 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3357 (Fframe_face_alist): Use decode_live_frame.
3358 * xfns.c (check_x_frame): Likewise.
3360 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3362 * window.c (quad): New function.
3363 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3364 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3365 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3366 (Fwindow_line_height): Use it.
3367 (Fwindow_fringes): Use list3.
3368 (Fwindow_scroll_bars): Use list4.
3369 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3370 (Fwindow_combination_limit): Allow zero number of arguments.
3372 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3374 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3376 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3377 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3378 file descriptor 2 for standard error. (Bug#12805)
3380 2012-11-05 Chong Yidong <cyd@gnu.org>
3382 * process.c (wait_reading_process_output): Revert previous change.
3384 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3386 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3387 This removes code that has been obsolete since around 1990.
3388 * callproc.c (Fcall_process):
3390 * process.c (create_process):
3391 * term.c (dissociate_if_controlling_tty):
3392 Assume setsid exists.
3393 * callproc.c (child_setup): Assume setpgid exists and behaves as
3394 per POSIX.1-1988 or later.
3395 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3396 * emacs.c (shut_down_emacs):
3397 * sysdep.c (sys_suspend, init_foreground_group):
3398 Assume getpgrp behaves as per POSIX.1-1998 or later.
3399 * msdos.c (setpgrp): Remove.
3400 (tcgetpgrp, setpgid, setsid): New functions.
3401 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3402 * term.c (no_controlling_tty): Remove; unused.
3403 * w32proc.c (setpgrp): Remove.
3404 (setsid, tcgetpgrp): New functions.
3406 Simplify by assuming __fpending.
3407 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3408 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3409 Do not assume that __fpending's result fits in int.
3411 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3413 Remove EMACS_OUTQSIZE+sleep hack.
3414 * dispnew.c (update_frame_1): Remove hack for terminals slower
3415 than 2400 bps, which throttled Emacs by having it sleep.
3416 This code hasn't worked since at least 2007, when the multi-tty stuff
3417 was added, and anyway those old terminals are long dead.
3418 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3419 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3421 Fix data-loss with --version (Bug#9574).
3422 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3423 as we can't assume that emacs_strerror is initialized, and strerror
3424 is good enough here.
3425 (main): Invoke atexit earlier, to catch earlier instances of
3426 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3428 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3430 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3431 (keyDown): Remap keypad keys to X11 virtual key codes.
3433 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3435 Fix data-loss with --batch (Bug#9574).
3436 * emacs.c: Include <close-stream.h>.
3437 (close_output_streams): New function.
3438 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3439 and handles errors appropriately.
3440 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3443 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3444 The symptom is a diagnostic "GLib-WARNING **: In call to
3445 g_spawn_sync(), exit status of a child process was requested but
3446 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3447 waitpid(), so exit status can't be returned." The diagnostic
3448 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3449 The real bug is a race condition between Emacs and glib: Emacs
3450 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3451 so that glib can't find it. Work around the bug by invoking
3452 waitpid only on subprocesses that Emacs itself creates.
3453 * process.c (create_process, record_child_status_change):
3454 Don't use special value -1 in pid field, as the caller now must
3455 know the pid rather than having the callee infer it.
3456 The inference was sometimes incorrect anyway, due to another race.
3457 (create_process): Set new 'alive' member if child is created.
3458 (process_status_retrieved): New function.
3459 (record_child_status_change): Use it.
3460 Accept negative 1st argument, which means to wait for the
3461 processes that Emacs already knows about. Move special-case code
3462 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3463 processes that have already been waited for, by testing and
3464 clearing new 'alive' member.
3465 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3466 now does this internally.
3467 (handle_child_signal): Let record_child_status_change do all
3468 the work, since we do not want to reap all exited child processes,
3469 only the child processes that Emacs itself created.
3470 * process.h (Lisp_Process): New boolean member 'alive'.
3472 Omit duplicate definitions no longer needed with gcc -g3.
3473 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3474 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3475 Define only as macros. There's no longer any need to also define
3476 these symbols as enums or as constants, since we now assume
3477 gcc -g3 when debugging.
3479 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3481 * lisp.mk: Adjust comments to the fact that term/internal is now
3482 loaded from loadup.el.
3484 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3485 (msdos_fatal_signal): New function.
3486 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3489 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3490 for GCC versions before 4.
3491 (emacs_raise): Define to call msdos_fatal_signal.
3493 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3494 iterator when starting in the middle of a display or overlay
3497 2012-11-03 Chong Yidong <cyd@gnu.org>
3499 * process.c (wait_reading_process_output): Clean up the last
3502 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3504 * process.c (wait_reading_process_output): Avoid a race condition
3505 with SIGIO delivery (Bug#11536).
3507 2012-11-03 Chong Yidong <cyd@gnu.org>
3509 * buffer.c (cursor_type): Untabify docstring.
3511 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3513 * frame.h (struct frame): Drop can_have_scroll_bars member
3514 which is meaningless for a long time. Adjust comments.
3515 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3516 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3518 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3520 * window.c (decode_next_window_args): Update window arg after
3521 calling decode_live_window and so fix crash reported at
3522 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3523 by Juanma Barranquero <lekktu@gmail.com>.
3524 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3525 * font.c (Ffont_at): Likewise.
3527 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3529 * widget.c (resize_cb): New function.
3530 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3531 (EmacsFrameResize): Check if all is up to date before changing frame
3534 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3536 Implement backtrace output for fatal errors on MS-Windows.
3537 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3538 (BACKTRACE_LIMIT_MAX): New macro.
3539 (w32_backtrace): New function.
3540 (emacs_abort): Use w32_backtrace when the user chooses not to
3541 attach a debugger. Update the text of the abort dialog.
3543 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3545 Window-related stuff cleanup here and there.
3546 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3547 Use decode_any_window.
3548 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3549 * xdisp.c (Fformat_mode_line): Likewise.
3550 * font.c (Ffont_at): Use decode_live_window.
3551 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3552 * window.c (decode_next_window_args): Likewise.
3553 (decode_any_window): Remove static.
3554 * window.h (decode_any_window): Add prototype.
3555 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3556 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3559 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3561 Remove pad from struct input_event.
3562 * termhooks.h (struct input_event): Remove padding field.
3564 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3565 member is never cons for a long time. Adjust comment.
3566 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3567 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3568 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3569 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3571 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3573 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3575 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3577 Fix crash when using Emacs as commit editor for git (Bug#12697).
3578 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3579 and it is configured in conf_post.h.
3580 (Fcall_process): Don't invoke both setsid and setpgid; the former
3581 is enough, if it exists.
3582 * callproc.c (Fcall_process, child_setup):
3583 * process.c (create_process): Use setpgid.
3584 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3586 * dispnew.c (init_display): Initialize the foreground group
3587 if we are running a tty display.
3588 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3589 * lisp.h (init_foreground_group): New decl.
3590 * sysdep.c (inherited_pgroup): New static var.
3591 (init_foreground_group, tcsetpgrp_without_stopping)
3592 (narrow_foreground_group, widen_foreground_group): New functions.
3593 (init_sys_modes): Narrow foreground group.
3594 (reset_sys_modes): Widen foreground group.
3596 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3598 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3600 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3602 * minibuf.c (read_minibuf): Restore current buffer since
3603 choose_minibuf_frame calling Fset_frame_selected_window may
3604 change it (Bug#12766).
3606 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3608 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3610 2012-10-30 Kenichi Handa <handa@gnu.org>
3612 * font.c (Ffont_at): If WINDOW is specified and it is not
3613 displaying the current buffer, signal an error.
3615 2012-10-29 Daniel Colascione <dancol@dancol.org>
3617 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3618 In preparation for fixing bug#12739, move these functions from
3621 * coding.h, coding.c: ... to here, and compile them only when
3622 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3623 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3625 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3627 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3628 (timer_loop, getitimer, setitimer): Use it instead of
3629 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3631 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3634 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3636 * nsterm.m (NO_APPDEFINED_DATA): New define.
3637 (last_appdefined_event_data): New variable
3638 (last_appdefined_event): Remove.
3639 (ns_select): Initialize t from last_appdefined_event_data instead
3640 of [last_appdefined_event data1].
3641 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3642 remove last_appdefined_event (Bug#12698).
3644 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3646 * frame.c (x_set_font): Catch internal error.
3648 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3650 Avoid overflow in w32 implementation of interval timers.
3651 When possible, for ITIMER_PROF count only times the main thread
3653 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3654 'volatile ULONGLONG' types. All the other data which was
3655 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3656 (GetThreadTimes_Proc): New typedef.
3657 (w32_get_timer_time): New function, returns a suitable time value
3659 (timer_loop): Enter critical section when accessing ULONGLONG
3660 values of the itimer_data struct, as these accesses are no longer
3661 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3662 Remove unused variable.
3663 (init_timers): Initialize s_pfn_Get_Thread_Times.
3664 (start_timer_thread): Don't assign itimer->caller_thread here.
3665 (getitimer): Assign itimer->caller_thread here.
3666 (setitimer): Always call getitimer to get the value of ticks_now.
3667 (sys_spawnve): Avoid compiler warning about format mismatch.
3669 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3671 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3672 mouse movement events if the menu bar is active. This avoids
3673 producing a busy "hour-glass" cursor by Windows if the mouse
3674 pointer is positioned over a tooltip shown for some menu item.
3676 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3678 Don't assume process IDs fit in int.
3679 * emacs.c (shut_down_emacs) [!DOS_NT]:
3680 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3681 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3682 Use pid_t, not int, to store process IDs, as 'int'
3683 is not wide enough on a few platforms (e.g., AIX and IRIX).
3685 2012-10-23 Kenichi Handa <handa@gnu.org>
3687 The following change is to make face-font-rescale-alist work
3688 correctly for non-ASCII fonts.

4171 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4173 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4174 of w32inevt.o from SOME_MACHINE_OBJECTS.
4176 2012-10-08 Daniel Colascione <dancol@dancol.org>
4178 * image.c: Permanent fix for JPEG compilation issue --- limit
4179 jpeglib `boolean' redefinition to Cygwin builds.
4181 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4183 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4185 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4188 2012-10-08 Daniel Colascione <dancol@dancol.org>
4190 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4191 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4192 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4193 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4194 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4195 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4196 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4197 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4198 now a supported configuration.
4200 * Makefile.in: consolidate image variables into LIBIMAGE; add
4201 W32_OBJ and W32_LIBS. Compile new files.
4204 (_DebPrint) declare tracing facility for W32 debugging. We need
4205 to unify tracing later.
4207 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4208 unconditional use of W32 Unicode functions. Cygwin runs only on
4209 100% Unicode operating systems.
4211 * cygw32.c: New file. Define Cygwin-specific facilities.
4212 (Fcygwin_convert_path_to_windows)
4213 (Fcygwin_convert_path_from_windows): New user functions for
4214 accessing Cygwin path-munging routines.
4216 * cygw32.h: New file.
4217 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4218 UTF-16LE strings temporarily inside non-Lisp-visible string
4221 (w32_strerror): Just what it says on the tin.
4223 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4224 also run for Cygwin; both systems have the same problem with using
4225 GUI facilities in a forked child. Also call syms_of_cygw32,
4226 syms_of_w32select in correct places.
4228 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4229 needs fork-then-exec for daemon launching.
4231 * font.h: Include frame.h.
4233 * image.c: Use the image library cache machinery only when we're
4234 compiling for native WINDOWSNT; Cygwin can use shared libraries
4235 like any other Unixlike system.
4237 * keyboard.c: Clarify a comment regarding the input loop.
4239 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4240 functions directly instead of trying to detect at runtime that our
4241 host operating system supports them. We make this change for two
4242 reasons: Cygwin lacks support for the multibyte character
4243 conversion functions used by the legacy menu code, and Cygwin
4244 never needs to rely on non-Unicode APIs.
4246 * unexw32.c (hinst): Declare extern.
4248 * w32.c: Change header order;
4249 (w32_strerror): Move to w32fns.c because we need it for
4250 non-WINDOWSNT builds.
4252 * w32.h: Add #error macro to make sure we don't include w32.h for
4253 Cygwin builds. Remove w32select declarations.
4255 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4256 w32fns.c. w32console.c is WINDOWSNT-only.
4258 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4259 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4261 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4262 (w32_major_version, w32_minor_version, w32_build_number)
4263 (os_subtype, sound_type): Define here
4264 (w32_defined_color): Make color parameter const for consistency
4265 with other _defined_color functions.
4266 (w32_createwindow): Unconditionally call w32_init_class instead of
4267 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4268 through the code is complex and unnecessary because class
4269 registration is practically free.
4270 (w32_name_of_message): New EMACSDEBUG-only function.
4271 (Fset_message_beep): Move here
4272 (Fx_open_connection): Require that the display name for Windows be
4273 "w32" for consistency, emacsclient disambiguation, and maybe, one
4274 day, multi-window-system support.
4275 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4276 Cygwin files for W32 GUI facilities, since these clearly don't
4277 expect Cygwin names.
4278 (_DebPrint): Define.
4279 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4280 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4281 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4282 (w32_last_error): Remove.
4284 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4286 * w32heap.c (syspage_mask): Declare here.
4287 (cache_system_info): Remove.
4289 * w32inevt.c (faked_key): Define globally, not statically.
4290 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4291 (w32_console_toggle_lock_key): Move to w32fns.c.
4293 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4295 * w32proc.c (_DebPrint): Move to w32fns.c.
4296 * w32select.c: Include string.h, stdio.h for Cygwin.
4297 * w32select.h: New File.
4299 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4301 (w32_message_fd): New variable. Under Cygwin, holds the file
4302 descriptor the system used to tell us about pending thread
4305 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4306 that prevented compilation under non-WINDOWSNT systems.
4308 (w32_initialize): Open /dev/windows and assign it to
4309 w32_message_fd. Provide w32 feature.
4311 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4312 (WM_EMACS_INPUT_READY): add.
4313 (prepend_msg, w32_message_fd): Declare globally.
4316 (keyboard_handle): Use only when WINDOWSNT.
4317 (notify_msg_ready): New function. Posts a message to the main
4318 thread's message queue under CYGWIN, which wakes up the main
4319 thread from select(2) by making the /dev/windows file descriptor
4320 ready. Under WINDOWSNT, it sets an event the same way the old
4323 (post, prepend_msg): Actually call notify_msg_ready instead of
4324 setting the input event directly.
4326 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4328 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4329 but it still has blocs in it, don't return it to the system,
4330 instead of aborting. (Bug#12402)
4332 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4334 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4336 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4337 MAC_OS_X_VERSION_10_6.
4338 (syms_of_nsterm): Remove comment about Panther and above for
4340 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4341 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4342 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4344 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4345 MAC_OS_X_VERSION_10_4.
4347 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4348 MAC_OS_X_VERSION_10_2.
4350 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4352 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4353 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4355 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4356 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4357 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4358 Remove ns_in_resize check.
4359 (ns_clear_frame_area): Remove resize handle code.
4361 * nsfns.m (ns_in_resize): Remove.
4362 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4363 Remove ns_in_resize check.
4365 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4367 Improve sys_siglist detection.
4368 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4369 defined as a macro, as is done in Solaris.
4370 (sys_siglist_entries): New macro.
4371 (save_strsignal): Use it.
4372 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4373 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4375 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4377 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4378 fullscreen/Fullscreen.
4380 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4381 tobar_height is new.
4383 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4384 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4385 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4386 (windowDidResize:): Check for correct window if old style fullscreen.
4387 Capitalize word in comment. Remove incorrect comment.
4388 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4389 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4390 error in drawing background.
4391 (toggleFullScreen:): Remove comment. Rearrange calls.
4392 Set toolbar values to zero, save old height in tobar_height.
4393 Restore tool bar height when leaving fullscreen.
4394 (canBecomeMainWindow): New function.
4396 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4398 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4400 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4402 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4404 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4405 that time stamps of directories could also be changed.
4406 Don't request the too broad GENERIC_WRITE, only the more restrictive
4407 FILE_WRITE_ATTRIBUTES access rights.
4409 * fileio.c (Fset_file_times): Special-case ignoring errors for
4410 directories only on MSDOS, not on MS-Windows.
4412 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4414 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4416 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4418 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4419 see whether CreateFile failed.
4421 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4423 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4424 to avoid similar races.
4425 * keyboard.c (pending_signals): Now bool, not int.
4427 Port timers to OpenBSD, plus check for timer failures.
4428 OpenBSD problem reported by Han Boetes.
4429 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4431 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4432 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4433 like OpenBSD, which has timer_settime but does not declare it.
4434 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4435 whether to use itimerspec-related primitives. All uses of
4436 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4438 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4440 * profiler.c (handle_profiler_signal): Fix a malloc race
4441 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4443 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4445 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4447 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4449 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4450 consistent with the change in return value of 'safe_strsignal'.
4452 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4454 Prefer plain 'static' to 'static inline' (Bug#12541).
4455 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4456 (bidi_set_sor_type, bidi_push_embedding_level)
4457 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4458 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4459 (bidi_cache_search, bidi_cache_ensure_space)
4460 (bidi_cache_iterator_state, bidi_cache_find)
4461 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4462 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4463 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4464 Now 'static', not 'static inline'.
4466 Count overruns when profiling; change units to ns.
4467 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4468 Give extra weight to samples after overruns, to attempt to count
4469 the time more accurately.
4470 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4471 the underlying primitives nominally do ns.
4472 (Fprofiler_cpu_start): Document the change. Mention that
4473 the sampling intervals are only approximate.
4475 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4477 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4479 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4480 case for the special 0 coding-system.
4482 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4483 (Fmake_overlay): Remove redundant tests.
4484 (fix_start_end_in_overlays): Remove redundant recentering.
4486 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4488 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4489 Update dependencies.
4491 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4493 Fix a malloc race condition involving strsignal.
4494 A signal can arrive in the middle of a malloc, and Emacs's signal
4495 handler can invoke strsignal, which can invoke malloc, which is
4496 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4497 Fix it by altering the signal handler so that it does not invoke
4499 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4500 * process.c (status_message): Use const pointer, in case strsignal
4501 is #defined to safe_strsignal.
4502 * sysdep.c (sys_siglist, init_signals): Always define and
4503 initialize a substitute sys_siglist if the system does not define
4504 one, even if HAVE_STRSIGNAL.
4505 (safe_strsignal): Rename from strsignal. Always define,
4506 using sys_siglist. Return a const pointer.
4507 * syssignal.h (safe_strsignal): New decl.
4508 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4510 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4512 * w32proc.c (timer_loop): Fix code that waits for timer
4513 expiration, to avoid high CPU usage.
4515 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4517 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4518 (sweep_weak_table): Remove redundant prototypes.
4520 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4522 * emacs.c: Move the inclusion of TERM_HEADER after including
4523 windows.h on WINDOWSNT. This avoids compilation problems with
4526 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4528 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4529 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4530 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4531 as the previous version used 'void *'.
4533 * ralloc.c (ROUNDUP): Fix last change.
4534 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4537 * w32proc.c <disable_itimers>: New static flag.
4538 (init_timers): Initialize it to zero, after creating the critical
4539 sections used by the timer threads.
4540 (term_timers): Set to 1 before deleting the critical sections.
4541 (getitimer, setitimer): If disable_itimers is non-zero, return an
4542 error indication without doing anything. Reported by Fabrice
4543 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4544 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4546 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4549 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4550 term_ntproc after all the other bookkeeping, to get timers working
4551 as long as possible.
4553 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4555 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4556 Suggested by Juri Linkov in
4557 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4559 Prefer plain 'static' to 'static inline' (Bug#12541).
4560 With static functions, modern compilers inline pretty well by
4561 themselves; advice from programmers often hurts as much as it helps.
4562 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4563 this change shrinks the text size of the Emacs executable by 1.1%
4564 without affecting CPU significantly in my benchmark.

4858 (handle_profiler_signal): Rename from sigprof_handler_1,
4859 for consistency with other handlers. Do not check whether
4860 cpu_log is a hash-table if garbage collecting, since it

4863 for consistency with other handlers.
4864 (setup_cpu_timer): New function, with much of what used to be in

4866 Prefer timer_settime if available, and prefer
4867 thread cputime clocks, then process cputime clocks, then
4868 monotonic clocks, to the old realtime clock. Use make_timeval
4869 to round more-correctly when falling back to setitimer.
4870 (Fprofiler_cpu_start): Use it.
4871 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4938 Since this stuff is now private to charset.c, there's no need for
4939 a public macro and no need to inline by hand.

5019 install term_ntproc as a signal handler for SIGABRT, as that
5020 should be done by the dumped Emacs.

5079 (scan_for_column, string_display_width, indented_beyond_p)
5080 (compute_motion, vmotion, Fvertical_motion):
5081 Use bool for booleans.
5083 2012-09-24 Chong Yidong <cyd@gnu.org>
5085 * chartab.c (Fset_char_table_default): Obsolete function removed.
5087 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5089 Move pid_t related decls out of lisp.h.
5090 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5091 (interruptible_wait_for_termination):
5092 Move these decls from lisp.h to syswait.h, since they use pid_t.
5093 Needed on FreeBSD; see Herbert J. Skuhra in
5094 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5095 * callproc.c: Include syswait.h.
5097 gnutls.c, gtkutil.c: Use bool for boolean.
5098 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
5099 (emacs_gnutls_handle_error):
5100 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)

5113 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5114 * xfns.c (Fx_show_tip) [USE_GTK]:
5115 Use bool for boolean.
5116 * gtkutil.c (xg_update_frame_menubar):
5117 * xmenu.c (update_frame_menubar):
5118 Return void, not int, since caller ignores return value.
5119 * gtkutil.c (xg_change_toolbar_position):
5122 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5124 * makefile.w32-in (BLOCKINPUT_H): Remove.

5141 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5143 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5144 fatal_error_backtrace.
5146 * w32proc.c (sys_kill): Undo last change: don't do anything when
5147 invoked to deliver SIGABRT to our own process. This is now
5148 handled by emacs_raise.
5150 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5152 * w32term.c (w32_read_socket): Remove leftover reference to
5153 interrupt_input_pending.
5155 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5157 Do not use SA_NODEFER.
5158 Problem reported by Dani Moncayo in
5159 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5161 * sysdep.c (emacs_abort): Do not reset signal handler.
5162 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5163 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5164 wanted even on POSIXish hosts, and it doesn't work on Windows.
5166 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5168 * xterm.c (x_term_init): Call fixup_locale before and after calling
5169 gtk_init (Bug#12392).
5171 2012-09-23 Chong Yidong <cyd@gnu.org>
5173 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5174 Vdynamic_library_alist.
5176 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5177 (Fgnutls_available_p): Caller changed.
5179 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5180 (Flibxml_parse_xml_region): Likewise.
5182 * dispextern.h (struct image_type): Remove arg from init function.
5184 * image.c (Finit_image_library, lookup_image_type)
5185 (define_image_type): Remove now-unneeded second arg.
5186 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5187 (init_tiff_functions, init_gif_functions, init_svg_functions):
5188 Arglist and w32_delayed_load calling convention changed.
5189 (gs_type): Remove init_gs_functions; there is no such function.
5190 (valid_image_p, make_image): Fix caller to lookup_image_type.
5192 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5194 Simplify and avoid signal-handling races (Bug#12471).
5196 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5197 Avoid recursive loop if there's a fatal error in the function itself.
5198 * atimer.c (pending_atimers):
5199 * blockinput.h: Don't include "atimer.h"; no longer needed.
5200 (interrupt_input_pending): Remove. All uses removed.
5201 pending_signals now counts both atimers and ordinary interrupts.
5202 This is less racy than having three separate pending-signal flags.
5203 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5205 Rename from their upper-case counterparts BLOCK_INPUT,
5206 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5207 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5208 This makes it easier to access volatile variables more accurately.
5209 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5210 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5211 that's more reliable if the code is buggy and sets
5212 interrupt_input_blocked to a negative value. All uses changed.
5213 * atimer.c (deliver_alarm_signal):
5214 Remove. No need to deliver this to the parent; any thread can
5215 handle this signal now. All uses replaced by underlying handler.
5216 * atimer.c (turn_on_atimers):
5217 * dispnew.c (handle_window_change_signal):
5218 * emacs.c (handle_danger_signal):
5219 * keyboard.c (kbd_buffer_get_event):
5220 Don't reestablish signal handler; not needed with sigaction.
5221 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5223 Rework to avoid unnecessary accesses to volatile variables.
5224 (UNBLOCK_INPUT_TO): Now a function.
5225 (totally_unblock_input, unblock_input): New decls.
5226 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5227 (init_data): Remove. Necessary stuff now done in init_signal.
5228 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5229 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5230 (fatal_error_code): Remove; no longer needed.
5231 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5232 it doesn't always backtrace. All uses changed. No need to reset
5233 signal to default, since sigaction and/or die does that for us now.
5234 Use emacs_raise (FOO), not kill (getpid (), FOO).
5235 (main): Check more-accurately whether we're dumping.
5236 Move fatal-error setup to sysdep.c
5237 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5238 * gtkutil.c (xg_get_file_name, xg_get_font):
5239 Remove no-longer-needed signal-mask manipulation.
5240 * keyboard.c, process.c (POLL_FOR_INPUT):
5241 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5242 * keyboard.c (read_avail_input): Remove.
5243 All uses replaced by gobble_input.
5244 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5245 (kbd_buffer_store_event_hold, gobble_input):
5246 (record_asynch_buffer_change) [USABLE_SIGIO]:
5247 (store_user_signal_events):
5248 No need to mess with signal mask.
5249 (gobble_input): If blocking input and there are terminals, simply
5250 set pending_signals to 1 and return. All hooks changed to not
5251 worry about whether input is blocked.
5252 (process_pending_signals): Clear pending_signals before processing
5253 them, in case a signal comes in while we're processing.
5254 By convention callers now test pending_signals before calling us.
5255 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5256 New functions, to support changes to blockinput.h.
5257 (handle_input_available_signal): Now extern.
5258 (reinvoke_input_signal): Remove. All uses replaced by
5260 (quit_count): Now volatile, since a signal handler uses it.
5261 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5262 All callers changed. Block SIGINT only if not already blocked.
5263 Clear sigmask reliably, even if Fsignal returns, which it can.
5264 Omit unnecessary accesses to volatile var.
5265 (quit_throw_to_read_char): No need to restore sigmask.
5266 * keyboard.c (gobble_input, handle_user_signal):
5267 * process.c (wait_reading_process_output):
5268 Call signal-handling code rather than killing ourselves.
5269 * lisp.h: Include <float.h>, for...
5270 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5271 (pending_signals): Now volatile.
5272 (syms_of_data): Now const if IEEE floating point.
5273 (handle_input_available_signal) [USABLE_SIGIO]:
5274 (terminate_due_to_signal, record_child_status_change): New decls.
5275 * process.c (create_process): Avoid disaster if memory is exhausted
5276 while we're processing a vfork, by tightening the critical section
5278 (send_process_frame, process_sent_to, handle_pipe_signal)
5279 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5281 (send_process): No need for setjmp/longjmp any more, since the
5282 SIGPIPE stuff is now gone. Instead, report an error if errno
5284 (record_child_status_change): Now extern. PID and W are now args.
5285 Return void, not bool. All callers changed.
5286 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5287 Remove. All uses removed. This bug should be fixed now in a
5289 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5290 and record the child status change directly. This avoids the
5291 need to futz with the signal mask.
5292 (process_fatal_action): Move here from emacs.c.
5293 (emacs_sigaction_flags): New function, containing
5294 much of what used to be in emacs_sigaction_init.
5295 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5296 caught by emacs, to make races less likely.
5297 (deliver_process_signal): Rename from handle_on_main_thread.
5299 (BACKTRACE_LIMIT_MAX): Now at top level.
5300 (thread_backtrace_buffer, threadback_backtrace_pointers):
5302 (deliver_thread_signal, deliver_fatal_thread_signal):
5303 New functions, for more-accurate delivery of thread-specific signals.
5304 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5305 (deliver_arith_signal): Handle in this thread, not
5306 in the main thread, since it's triggered by this thread.
5307 (maybe_fatal_sig): New function.
5308 (init_signals): New arg DUMPING so that we can be more accurate
5309 about whether we're dumping. Caller changed.
5310 Treat thread-specific signals differently from process-general signals.
5311 Block all signals while handling fatal error; that's safer.
5312 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5314 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5315 Ignore SIGPIPE unless batch.
5316 (emacs_backtrace): Output backtrace for the appropriate thread,
5317 which is not necessarily the main thread.
5318 * syssignal.h: Include <stdbool.h>.
5319 (emacs_raise): New macro.
5320 * xterm.c (x_connection_signal): Remove; no longer needed
5321 now that we use sigaction.
5322 (x_connection_closed): No need to mess with sigmask now.
5323 (x_initialize): No need to reset SIGPIPE handler here, since
5324 init_signals does this for us now.
5326 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5328 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5329 background rect may be larger (Bug#12245).
5331 2012-09-23 Chong Yidong <cyd@gnu.org>
5333 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5335 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5337 * .gdbinit: Just stop at fatal_error_backtrace.
5338 See Stefan Monnier's request in
5339 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5340 Remove no-longer-used query of system type.
5342 2012-09-22 Chong Yidong <cyd@gnu.org>
5344 * search.c (Freplace_match): Doc fix (Bug#12325).
5346 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5348 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5349 (Fline_end_position): Doc fix.
5351 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5353 2012-09-22 Chong Yidong <cyd@gnu.org>
5355 * dispextern.h (struct image_type): Add new slot, storing a type
5356 initialization function.
5358 * image.c (define_image_type): Call the image initializer function
5359 if it is defined. Arguments and return value changed.
5360 (valid_image_p, make_image): Callers changed.
5361 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5362 (gif_type, imagemagick_type, svg_type, gs_type):
5363 Add initialization functions.
5364 (Finit_image_library): Call lookup_image_type.
5365 (CHECK_LIB_AVAILABLE): Macro deleted.
5366 (lookup_image_type): Call define_image_type here, rather than via
5367 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5368 (syms_of_image): Move define_image_type calls for xbm_type and
5369 pbm_type to lookup_image_type.
5371 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5373 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5374 'idle_timers' from here ...
5375 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5376 lists, to avoid infloops when the timer does something stupid,
5377 like reinvoke itself with the same or smaller time-out.
5380 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5382 * window.c (Fsplit_window_internal): Handle only Qt value of
5383 Vwindow_combination_limit separately.
5384 (Qtemp_buffer_resize): New symbol.
5385 (Vwindow_combination_limit): New default value.
5388 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5390 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5391 the new overlay string. (Bug#10159)
5393 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5395 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5396 or that fprintf is async-signal-safe. POSIX doesn't require
5399 2012-09-22 Chong Yidong <cyd@gnu.org>
5401 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5404 2012-09-22 Kenichi Handa <handa@gnu.org>
5406 * composite.c (composition_reseat_it): Handle the case that a
5407 grapheme cluster is not covered by a single font (Bug#12352).
5409 2012-09-21 Chong Yidong <cyd@gnu.org>
5411 * image.c (define_image_type): Avoid adding duplicate types to
5412 image_types (Bug#12463). Suggested by Jörg Walter.
5414 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5416 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5417 (print_load_command_name): Add case LC_DATA_IN_CODE.
5418 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5420 2012-09-21 Glenn Morris <rgm@gnu.org>
5422 * eval.c (Frun_hook_with_args_until_success)
5423 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5425 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5427 * fileio.c (Ffile_selinux_context): Only call freecon when
5428 lgetfilecon succeeded.
5429 (Fset_file_selinux_context): Likewise. (Bug#12444)
5431 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5433 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5434 reordering, locate the cursor by calling set_cursor_from_row; if
5435 that fails, clear the desired glyph matrix before returning a
5436 failure indication to the caller. Fixes leaving garbled display
5437 when fast scrolling with a down-key. (Bug#12403)
5438 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5439 scrolling through multibyte text.
5441 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5443 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5444 calling mark_vectorlike since that's the one that marks the window.
5445 (mark_discard_killed_buffers): Mark the final cdr.
5446 * window.h (struct window): Move prev/next_buffers to the
5447 non-standard fields.
5448 * window.c (make_window): Initialize prev/next_buffers manually.
5450 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5452 Omit unused arg EXPECTED from socket hooks.
5453 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5454 * nsterm.m (ns_term_init):
5455 * termhooks.h (struct terminal.read_socket_hook):
5456 * w32inevt.c (w32_console_read_socket):
5457 * w32term.c (w32_read_socket):
5458 * xterm.c (XTread_socket):
5459 Omit unused arg EXPECTED. All callers changed.
5460 (store_user_signal_events): Return void, not int, since callers no
5461 longer care about the return value. All uses changed.
5463 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5465 * w32gui.h (XParseGeometry): Do not declare.
5467 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5469 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5470 Ignore 'expected'. See Eli Zaretskii in
5471 <http://bugs.gnu.org/12471#8> (last line).
5473 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5474 (XParseGeometry): Now static. Substitute extremal values for
5475 values that are out of range.
5477 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5479 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5481 * nsfns.m (XParseGeometry): Remove.
5482 (Fx_create_frame): Call x_set_offset to correctly interpret
5483 top_pos in geometry.
5485 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5486 (Fx_parse_geometry): If there is a space in string, call
5487 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5489 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5491 * search.c (scan_buffer): Use character positions in calls to
5492 region_cache_forward and region_cache_backward, not byte
5493 positions. (Bug#12196)
5495 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5496 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5498 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5499 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5500 emacs_blocked_malloc, now deleted.
5502 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5504 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5505 The workaround was for improving performance on Solaris 2.4, but
5506 is getting in the way now. Emacs will still work if someone is
5507 still running Solaris 2.4 in a museum somewhere; Sun dropped
5508 support for Solaris 2.4 in 2003.
5509 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5510 * process.c (create_process) [HAVE_WORKING_VFORK]:
5511 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5512 since Emacs no longer uses vfork on that platform.
5514 2012-09-17 Glenn Morris <rgm@gnu.org>
5516 * emacs.c: Use COPYRIGHT.
5518 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5520 Remove configure's --without-sync-input option (Bug#12450).
5521 When auditing signal-handling in preparation for cleaning it up,
5522 I found that SYNC_INPUT has race conditions and would be a real
5523 pain to fix. Since it's an undocumented and deprecated
5524 configure-time option, now seems like a good time to remove it.
5525 Also see <http://bugs.gnu.org/11080#16>.
5526 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5527 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5528 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5529 (malloc_hysteresis):
5530 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5531 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5532 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5533 (dont_register_blocks, bytes_used_when_reconsidered)
5534 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5535 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5536 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5537 Remove. All uses removed.
5538 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5539 implementation, one that depends on whether the new macro
5540 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5542 * atimer.c (run_timers, handle_alarm_signal):
5543 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5544 (handle_async_input, process_pending_signals)
5545 (handle_input_available_signal, init_keyboard):
5546 * nsterm.m (ns_read_socket):
5547 * process.c (wait_reading_process_output):
5548 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5549 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5551 * xterm.c (XTread_socket):
5553 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5554 * eval.c (handling_signal): Remove. All uses removed.
5555 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5556 All uses replaced with the SYNC_INPUT version.
5557 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5559 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5562 * font.c (Ffont_shape_gstring): Remove unused local.
5564 2012-09-16 Glenn Morris <rgm@gnu.org>
5566 * Makefile.in (clean): No longer run nextstep's clean.
5568 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5570 (ns-app): Move here from ns.mk, and simplify.
5571 (clean): Simplify nextstep entry.
5572 * ns.mk: Remove file.
5574 2012-09-17 Kenichi Handa <handa@gnu.org>
5576 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5577 not covert the last few charactes.
5579 2012-09-16 Kenichi Handa <handa@gnu.org>
5581 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5582 here, but just check the validity of glyphs in the glyph-string.
5584 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5586 * window.c (Fwindow_parameter, Fset_window_parameter):
5587 Accept any window as argument (Bug#12452).
5589 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5591 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5592 to ns_term_init to avoid memory leak.
5594 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5595 explicit retain/release.
5596 (ns_term_init): Only allow one display. Initialize outerpool and
5599 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5601 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5602 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5603 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5604 the Microsoft problem in a different way, by altering ../nt/config.nt.
5606 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5621 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5622 by lisp.h. This completes removal of setjmp.h inclusion
5623 erroneously announced in the previous commit. (Bug#12446)
5625 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5628 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5629 not defined as a macro. The latter happens on MS-Windows.
5632 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5634 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5635 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5636 Some instances of '#include <setjmp.h>' removed, if the
5637 only reason for the instance was because "lisp.h" was included.
5638 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5639 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5640 and _longjmp with the new symbols. Emacs already uses _setjmp if
5641 available, so this change affects only POSIXish hosts that have
5642 sigsetjmp but not _setjmp, such as some versions of Solaris and
5643 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5644 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5645 (png_load_body) [HAVE_PNG]:
5646 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5647 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5648 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5649 since PNG requires jmp_buf. This is the only exception to the
5650 general rule that we now use sys_setjmp and sys_longjmp.
5651 This exception is OK since this code does not change the signal
5652 mask or longjmp out of a signal handler.
5654 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5656 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5657 Include "syssignal.h", for 'main_thread'.
5659 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5661 Avoid out-of-range marker position (Bug#12426).
5662 * insdel.c (replace_range, replace_range_2):
5663 Adjust markers before overlays, as suggested by comments.
5664 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5665 Remove redundant check before calling offset_intervals.
5667 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5669 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5670 current buffer (Bug#12387).
5672 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5674 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5676 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5678 Use a more backwards-compatible timer format (Bug#12430).
5679 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5680 vector element, not from the 4th, since PSECS is now at the end.
5681 (Fcurrent_idle_time): Doc fix.
5683 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5685 Function to mark objects and remove killed buffers at once.
5686 * alloc.c (discard_killed_buffers): Rename to ...
5687 (mark_discard_killed buffers) ... new name. Add marking
5688 of remaining objects. Fix comment. Adjust users.
5689 (mark_object): Do not touch frame buffer lists here.
5690 * frame.c (delete_frame): Reset frame buffer lists here.
5692 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5694 Better workaround for GNOME bug when --enable-gcc-warnings.
5695 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5696 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5697 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5699 Simplify SIGIO usage (Bug#12408).
5700 The code that dealt with SIGIO was crufty and confusing, e.g., it
5701 played tricks like "#undef SIGIO" but these tricks were not used
5702 consistently. Simplify mostly by not #undeffing standard symbols,
5703 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5704 or not as we please) rather than "defined SIGIO" (standard symbol
5705 that we probably shouldn't #undef).
5706 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5707 Modules that need it can include it.
5708 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5709 * dispextern.h (ignore_sigio): New decl.
5710 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5711 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5712 * emacs.c (shut_down_emacs):
5713 * keyboard.c (kbd_buffer_store_event_hold):
5714 Use ignore_sigio rather than invoking 'signal' directly.
5715 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5717 (FIONREAD, SIGIO): Do not #undef.
5718 (tty_read_avail_input): Use #error rather than a syntax error.
5719 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5720 for I_PIPE, used by SETUP_SLAVE_PTY.
5721 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5722 * sysdep.c (croak): Remove; no longer needed. This bit of
5723 temporary code, with Fred N. Fish's comment that it's temporary,
5724 has been in Emacs since at least 1992!
5725 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5726 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5727 * syssignal.h (croak): Remove decl.
5728 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5729 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5730 now that we're termios-only.
5731 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5732 * term.c (dissociate_if_controlling_tty): Use #error rather than
5735 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5736 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5737 to work around GNOME bug 683906.
5738 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5739 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5740 This works around GCC bug 54561.
5742 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5744 More fixes for 'volatile' and setjmp/longjmp.
5745 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5746 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5747 (png_load_body) [HAVE_PNG]:
5748 (jpeg_load_body) [HAVE_JPEG]:
5749 New function, with most of the old parent function's body.
5750 (png_load) [HAVE_PNG]:
5751 (jpeg_load) [HAVE_JPEG]:
5752 Invoke the new function, to avoid longjmp munging our locals.
5753 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5754 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5755 longjmp is passed 2, as the C standard doesn't guarantee this.
5756 Instead, store the failure code into mgr->failure_code.
5758 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5760 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5761 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5762 (syms_of_keyboard): Remove support for unread-command-char.
5764 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5766 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5767 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5768 violation. (Bug#12426)
5770 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5772 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5774 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5776 * eval.c: Add `inhibit-debugger'.
5777 (Qinhibit_debugger): New symbol.
5778 (call_debugger): Bind it instead of Qdebug_on_error.
5779 (maybe_call_debugger): Test Vinhibit_debugger.
5780 (syms_of_eval): Define inhibit-debugger.
5781 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5782 (syms_of_xdisp): Remove inhibit-debug-on-message.
5784 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5786 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5787 If a nonvolatile local variable is written before a _longjmp to
5788 the frame containing the variable, and is read after the _longjmp,
5789 the value read is indeterminate. Some local variables of type
5790 'struct handler' and 'struct catchtag' are used in this way, so
5791 mark each of their slots as volatile if the slot can be set before
5792 _longjmp and read afterwards.
5793 * lisp.h (struct handler): var and chosen_clause are now volatile.
5794 (struct catchtag): val, next, and pdlcount are now volatile.
5796 * bidi.c (bidi_push_it, bidi_pop_it):
5797 * fns.c (copy_hash_table):
5798 * image.c (define_image_type):
5799 * keyboard.c (kbd_buffer_store_event_hold):
5800 * process.c (Fprocess_send_eof):
5801 * xfaces.c (x_create_gc) [HAVE_NS]:
5802 * xgselect.c (xg_select):
5803 Prefer assignment to memcpy when either will do.
5805 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5806 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5807 time an item is removed. No need to mark this function 'inline';
5808 the compiler knows better than we do.
5810 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5812 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5813 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5814 to change_frame_size (Bug#12388).
5815 (windowDidResize:): Pass YES to updateFrameSize.
5817 * nsterm.h: Add delay parameter to updateFrameSize.
5819 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5821 Discard killed buffers from deleted window and frame objects.
5822 This reduces an amount of references to killed buffers and
5823 helps GC to reclaim them faster.
5824 * alloc.c (discard_killed_buffers): New function.
5825 (mark_object): Use it for deleted windows and frames.
5826 (mark_object): If symbol's value is set up for a killed buffer
5827 or deleted frame, restore its global binding.
5828 * data.c (swap_in_global_binding): Add GC notice.
5829 (swap_in_symval_forwarding): Use convenient set_blv_where.
5830 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5831 * window.h: ... to here.
5833 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5835 Convenient macro to check whether the buffer is live.
5836 * buffer.h (BUFFER_LIVE_P): New macro.
5837 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5838 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5840 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5842 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5843 composition cases (Bug#12364).
5845 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5846 overhang of succeeding glyphs overlapping box cursor.
5848 * w32term.c (x_draw_glyph_string): Likewise.
5850 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5852 Simplify, document, and port floating-point (Bug#12381).
5853 The porting part of this patch fixes bugs on non-IEEE platforms
5854 with frexp, ldexp, logb.
5855 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5857 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5858 support, by removing commented-out code and briefly listing the
5859 C89 functions excluded. The commented-out stuff was confusing
5860 maintenance, e.g., we thought we needed cbrt but it was commented out.
5861 (logb): Remove decl; no longer needed.
5862 (isfinite): New macro, if not already supplied.
5863 (isnan): Don't replace any existing macro.
5864 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5865 are present on all C89 platforms.
5866 (Ffrexp): Do not special-case zero, as frexp does the right thing
5868 (Flogb): Do not use logb, as it doesn't have the desired meaning
5869 on hosts that use non-base-2 floating point. Instead, stick with
5870 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5871 frexp, to avoid getting an unspecified result.
5873 * xdisp.c (Qinhibit_debug_on_message): Now static.
5875 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5877 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5878 NSBezierPath (Bug#12131).
5880 2012-09-10 Chong Yidong <cyd@gnu.org>
5882 * fns.c (Fdelq, Fdelete): Doc fix.
5884 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5886 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5887 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5889 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5891 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5892 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5895 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5897 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5898 left fringe if the window has a left margin. This avoids leaving
5899 traces of the cursor because its leftmost pixel is not drawn over.
5901 * dispnew.c (update_window_line): When the left margin area of a
5902 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5903 that screen line. (Bug#12277)
5905 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5907 Assume C89 or later for math functions (Bug#12381).
5908 This simplifies the code, and makes it a bit smaller and faster,
5909 and (most important) makes it easier to clean up signal handling
5910 since we can stop worring about floating-point exceptions in
5911 library code. That was a problem before C89, but the problem
5912 went away many years ago on all practical Emacs targets.
5913 * data.c, image.c, lread.c, print.c:
5914 Don't include <math.h>; no longer needed.
5915 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5916 might be autoconfigured, as that never happens.
5918 * doprnt.c (DBL_MAX_10_EXP):
5919 * print.c (DBL_DIG):
5920 Remove. C89 or later always defines these.
5921 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5922 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5923 (arith_error, domain_error, domain_error2):
5924 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5925 no longer needed -- we simply return what C returns. All uses removed.
5926 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5928 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5929 Remove. All uses expanded, as these macros are no longer used
5930 more than once and are now more trouble than they're worth.
5931 (Ftan): Use tan, not sin / cos.
5932 (Flogb): Assume C89 frexp.
5933 (fmod_float): Assume C89 fmod.
5934 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5935 (init_floatfns): Remove. All uses removed.
5937 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5939 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5940 compositeToPoint for OSX < 10.6 (Bug#12390).
5942 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5944 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5945 This produces more-accurate results.
5947 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5949 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5950 changes (Bug#12088).
5952 2012-09-08 Chong Yidong <cyd@gnu.org>
5954 * syntax.c (Fstring_to_syntax): Doc fix.
5956 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5958 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5959 in the internal border.
5960 (x_set_window_size): Remove static variables and their usage.
5961 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5962 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5963 Remove fringe/internal border adjustment (Bug#11052).
5964 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5965 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5966 (ns_fix_rect_ibw): Remove.
5967 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5968 (ns_dumpglyphs_box_or_relief): Ditto.
5969 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5971 (ns_dumpglyphs_image): Ditto.
5972 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5974 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5975 their usage. Add fringe_extended_p and its use as in other terms.
5976 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5977 scroll bar was removed.
5978 (updateFrameSize): New function.
5979 (windowDidResize): Move code to updateFrameSize and call it.
5981 * nsterm.h (EmacsView): Add updateFrameSize.
5983 2012-09-07 Chong Yidong <cyd@gnu.org>
5985 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5987 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5989 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5991 More signal-handler cleanup (Bug#12327).
5992 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5993 Problem introduced when merging patches. Noted by Eli Zaretskii in
5994 <http://bugs.gnu.org/12327#67>.
5995 * floatfns.c: Comment fix.
5996 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5997 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5998 and anyway the declaration is harmless even if SIGDANGER is not defined.
5999 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6000 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6001 source files not surprisingly expected syssignal.h to define, or
6002 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6003 Include <sys/ioctl.h>, for FIONREAD.
6004 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6005 This eliminates a problem whereby other files mysteriously had
6006 to include "syssignal.h" before including "systty.h" if they
6007 wanted to use "#ifdef SIGIO".
6009 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6011 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6013 * w32.c (sigemptyset): Empty the set.
6014 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6016 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6018 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6020 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6021 (mark_object): Likewise for frame objects.
6023 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6025 * syssignal.h (handle_on_main_thread): Always declare,
6026 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6027 This ports to platforms without HAVE_PTHREAD.
6029 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6031 Signal-handler cleanup (Bug#12327).
6032 Emacs's signal handlers were written in the old 4.2BSD style with
6033 sigblock and sigmask and so forth, and this led to some
6034 inefficiencies and confusion. Rewrite these to use
6035 pthread_sigmask etc. without copying signal sets around. Also,
6036 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6037 'signal', and instead use functions that do not attempt to take
6038 over the system name space. This patch causes Emacs's text
6039 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6040 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6041 Do not include <signal.h> or "syssignal.h", as these
6042 modules do not use signals.
6043 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6044 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6045 Do not include <signal.h>, as "syssignal.h" does that for us now.
6046 * atimer.c (sigmask_atimers): New function.
6047 (block_atimers, unblock_atimers): New functions,
6048 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6050 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6051 no longer needed here.
6052 * emacs.c (main): Inspect existing signal handler with sigaction,
6053 so that there's no need to block and unblock SIGHUP.
6054 * sysdep.c (struct save_signal): New member 'action', replacing
6055 old member 'handler'.
6056 (save_signal_handlers, restore_signal_handlers):
6057 Use sigaction instead of 'signal' to save and restore.
6058 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6059 New function. All users of 'signal' modified to use set_sighandler
6060 if they're writeonly, and to use sys_signal if they're read+write.
6061 (emacs_sigaction_init, forwarded_signal): New functions.
6062 (sys_signal): Remove. All uses replaced by calls to sigaction
6063 and emacs_sigaction_init, or by direct calls to 'signal'.
6064 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6065 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6066 all uses replaced by pthread_sigmask etc. calls.
6067 * syssignal.h: Include <signal.h>.
6068 (emacs_sigaction_init, forwarded_signal): New decls.
6069 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6070 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6071 (sigmask, sys_sigmask): Remove; no longer needed.
6072 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6073 (sigblock, sigunblock, sigfree):
6074 (sigsetmask) [!defined sigsetmask]:
6075 Remove. All uses replaced by pthread_sigmask.
6076 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6077 no longer need to be replaced, and its typical old uses
6078 are now done via emacs_sigaction_init and sigaction.
6079 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6080 (sys_sigdel): Remove; unused.
6081 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6083 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6085 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6086 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6088 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6090 Explicitly mark buffer_defaults and buffer_local_symbols.
6091 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6092 mark_local_symbols here.
6093 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6094 since special buffers aren't marked here any more.
6095 (allocate_buffer): Chain new buffer with all_buffers here...
6096 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6098 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6099 (syms_of_buffer): Remove staticpro of the above.
6100 (init_buffer_once): Set names for buffer_defaults and
6101 buffer_local_symbols.
6103 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6105 Use bool for booleans in font-related modules.
6106 * font.c (font_intern_prop, font_style_to_value)
6107 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6108 (generate_otf_features, font_check_otf_features, font_check_otf)
6109 (font_match_p, font_list_entities, font_at):
6110 * fontset.c (fontset_id_valid_p, reorder_font_vector
6111 (fontset_find_font, Fset_fontset_font)
6112 (face_suitable_for_char_p) [0]:
6113 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6114 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6115 (m17n_flt_initialized, ftfont_shape_by_flt):
6116 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6117 * nsfont.m (nsfont_draw):
6118 * w32font.c (w32font_draw):
6119 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6120 Use bool for booleans.
6121 * font.h: Adjust to above API changes.
6122 (struct font, struct font_driver, struct font_driver_list):
6123 Use bool for booleans.
6124 (struct font): Remove useless member encoding_type.
6126 * fontset.c, xftfont.c: Omit unnecessary static decls.
6128 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6130 * alloc.c (mark_object): Revert window marking code
6131 since it's unsafe for the Fset_window_configuration.
6133 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6135 Fix race conditions with signal handlers and errno (Bug#12327).
6136 Be more systematic about preserving errno whenever a signal
6137 handler returns, even if it's not in the main thread. Do this by
6138 renaming signal handlers to distinguish between signal delivery
6139 and signal handling. All uses changed.
6140 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6141 * data.c (deliver_arith_signal): Rename from arith_error.
6142 * dispnew.c (deliver_window_change_signal): Rename from
6143 window_change_signal.
6144 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6145 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6146 * keyboard.c (deliver_input_available_signal): Rename from
6147 input_available_signal.
6148 (deliver_user_signal): Rename from handle_user_signal.
6149 (deliver_interrupt_signal): Rename from interrupt_signal.
6150 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6151 (deliver_child_signal): Rename from sigchld_handler.
6152 * atimer.c (handle_alarm_signal):
6153 * data.c (handle_arith_signal):
6154 * dispnew.c (handle_window_change_signal):
6155 * emacs.c (handle_fatal_signal, handle_danger_signal):
6156 * keyboard.c (handle_input_available_signal):
6157 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6158 * process.c (handle_pipe_signal, handle_child_signal):
6159 New functions, with the actual signal-handling code taken from the
6160 original respective signal handlers, sans the sporadic attempts to
6161 preserve errno, since that's now done by handle_on_main_thread.
6162 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6163 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6164 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6166 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6167 Move initialization of main_thread to sysdep.c's init_signals.
6168 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6169 our usage, and simplifies the mainline code.
6170 (record_child_status_change): New static function, as a helper
6171 for handle_child_signal, and with most of the old child handler's
6173 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6174 (handle_child_signal): Use the above.
6175 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6176 Moved here from emacs.c.
6177 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6178 code moved here from emacs.c's main function.
6179 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6180 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6181 This lets callers save and restore errno properly.
6183 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6185 Remove redundant or unused things here and there.
6186 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6187 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6188 * editfns.c (Fcompare_buffer_substrings): Likewise.
6189 * frame.h (struct terminal, struct font_driver_list):
6190 Remove redundant declarations.
6191 * window.h (Qleft, Qright): Likewise.
6193 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6195 Do not mark objects from deleted buffers, windows and frames.
6196 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6197 (mark_object): Likewise for windows and frames.
6199 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6201 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6202 buffer_defaults and buffer_local_symbols as valid objects.
6203 Return special value to denote them.
6205 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6207 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6208 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6209 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6210 (file_name_absolute_p, Fsubstitute_in_file_name):
6211 (check_executable, check_writable, Ffile_accessible_directory_p)
6212 (Fset_file_selinux_context, Fdefault_file_modes)
6213 (Finsert_file_contents, choose_write_coding_system)
6214 (Fwrite_region, build_annotations, a_write, e_write)
6216 * filelock.c (boot_time_initialized, get_boot_time)
6217 (get_boot_time_1, lock_file_1, within_one_second):
6218 * floatfns.c (in_float):
6219 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6220 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6221 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6222 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6223 * window.c (compare_window_configurations):
6224 Use bool for booleans.
6225 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6226 (Fdefault_file_modes): Now mode_t, not int, for modes.
6227 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6228 (internal_delete_file): Now returns void, not a (boolean) int,
6229 since nobody was looking at the return value.
6230 * lisp.h, window.h: Adjust to above API changes.
6232 * xdisp.c (set_message): Simplify and reindent last change.
6234 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6236 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6238 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6240 * eval.c (call_debugger): Make the function non-static so that we
6241 can call it from set_message.
6243 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6244 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6246 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6248 Give more-useful info on a fatal error (Bug#12328).
6249 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6250 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6251 of doing the work ourselves.
6252 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6253 do most of the work.
6254 (fatal_error_backtrace): New function, taken from the guts
6255 of the old fatal_error_signal, but with a new option to output
6257 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6258 info about the signal than just its number.
6259 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6260 * sysdep.c: Include <execinfo.h>
6261 (emacs_backtrace): New function, taken partly from the previous
6262 code of the 'die' function.
6263 (emacs_abort): Call fatal_error_backtrace rather than abort.
6265 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6267 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6268 eager (load-time) macro-expansion.
6269 * lisp.mk (lisp): Add macroexp.
6271 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6273 Simplify redefinition of 'abort' (Bug#12316).
6274 Do not try to redefine the 'abort' function. Instead, redo
6275 the code so that it calls 'emacs_abort' rather than 'abort'.
6276 This removes the need for the NO_ABORT configure-time macro
6277 and makes it easier to change the abort code to do a backtrace.
6278 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6279 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6280 Remove; sysdep.c's emacs_abort now takes its place.
6281 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6282 'abort' changed to use 'emacs_abort'.
6283 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6284 (abort) [!defined abort]: Rename to ...
6285 (emacs_abort): ... new name.
6286 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6287 the place of the old 'abort' in emacs.c.
6288 * w32.c, w32fns.c (abort): Do not #undef.
6289 * w32.c (emacs_abort): Rename from w32_abort.
6291 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6293 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6294 offsets[j].dv, since the y axis of the screen coordinates points
6295 down, while the y axis of the font definition coordinates points
6296 up. This fixes display of Arabic diacritics such as KASRA and
6297 KASRATAN. (Bug#11860)
6299 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6301 Be more systematic about _setjmp vs setjmp.
6302 * alloc.c (test_setjmp, mark_stack):
6303 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6304 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6305 (png_load, my_error_exit, jpeg_load):
6306 * process.c (send_process_trap, send_process):
6307 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6308 The underscored versions are up to 30x faster on some hosts.
6309 Formerly, the code used setjmp+longjmp sometimes and
6310 _setjmp+_longjmp at other times, with no particular reason to
6311 prefer setjmp+longjmp.
6313 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6315 Fix minor problem found by static checking.
6316 * buffer.c (Fdelete_all_overlays): Return nil.
6318 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6320 * buffer.c (Fdelete_all_overlays): New function.
6322 2012-09-03 Chong Yidong <cyd@gnu.org>
6324 * gtkutil.c: Add extern decl for Qxft.
6326 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6328 * emacs.c, eval.c: Use bool for boolean.
6329 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6330 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6331 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6332 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6333 (main, decode_env_path, Fdaemon_initialized):
6334 * eval.c (call_debugger, Finteractive_p, interactive_p):
6335 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6336 (maybe_call_debugger, Fbacktrace):
6337 * process.c (read_process_output, exec_sentinel):
6338 Use bool for booleans.
6339 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6340 All callers changed.
6341 * eval.c (interactive_p): Omit always-true boolean argument
6342 EXCLUDE_SUBRS_P. All callers changed.
6343 * dispextern.h, lisp.h: Reflect above API changes.
6344 * firstfile.c (dummy): Use the address of 'main', whose signature
6345 won't change, instead of the address of 'initialize', whose
6346 signature just changed from int to bool.
6347 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6348 * msdos.c (fatal_error_in_progress): ... from here.
6349 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6351 (redisplay_internal, unwind_redisplay): Simply clear
6352 REDISPLAYING_P when unwinding, instead of saving its previous,
6353 always-false value and then restoring it.
6355 Clean up some extern decls.
6356 Mostly, this hoists extern decls out of .c files and into .h files.
6357 That way, we're more likely to catch errors if the interfaces change.
6358 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6359 declare xg_mark_data.
6360 * dispextern.h (x_frame_parm_handlers):
6362 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6363 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6364 (Qultra_bold, Qoblique, Qitalic):
6365 Move extern decl here from .c file.
6366 * alloc.c (xg_mark_data) [USE_GTK]:
6368 * eval.c (Qlexical_binding):
6369 * fns.c (time) [!HAVE_UNISTD_H]:
6370 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6371 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
6372 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
6373 * lread.c (Qinternal_interpreter_environment):
6374 * minibuf.c (Qbuffer):
6375 * process.c (QCfamily, QCfilter):
6376 * widget.c (free_frame_faces):
6377 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6378 * xfont.c (x_clear_errors):
6379 * xterm.c (x_frame_parm_handlers):
6380 Remove now-redundant extern decls.
6381 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:

6445 offset adjustment values separately for each cluster. (Bug#11860)
6447 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6448 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6449 about implicit conversions from integer to pointer.

6507 window system declarations.
6509 * frame.h: Move common functions here: set_frame_menubar,
6510 x_set_window_size, x_sync, x_get_focus_frame,
6511 x_set_mouse_position, x_set_mouse_pixel_position,
6512 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6569 for GCC 4.7.1 x86-64.
6571 2012-08-30 Glenn Morris <rgm@gnu.org>
6573 * lread.c (init_lread): For out-of-tree builds, only add the
6574 source directory's site-lisp dir to the load-path if it exists,
6575 consistent with in-tree builds. (Bug#12302)
6577 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6807 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6808 are all boolean, so make them single-bit bitfields.
6810 * lisp.h (ASET): Remove attempt to detect side effects.
6811 It was meant to be temporary and it often doesn't work,
6812 because when IDX has side effects the behavior of IDX==IDX
6813 is undefined. See Stefan Monnier in
6814 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6816 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6824 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6825 as that's faster and simpler than static storage. Don't bother
6826 with the g_main_context_query overhead if g_main_context_pending
6827 says no events are pending.
6828 (gfds, gfds_size): Remove these static vars.
6829 (xgselect_initialize): Remove; no longer needed.
6830 All uses and decls removed.
6832 * emacs.c (fatal_error_signal_hook): Remove.
6833 All uses removed. This leftover from old code was always 0.
6835 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6836 * casefiddle.c (casify_object, casify_region):
6837 * casetab.c (set_case_table):
6838 * category.c, category.h (word_boundary_p):
6839 * category.h (CHAR_HAS_CATEGORY):
6840 Use bool for booleans, instead of int.
6842 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6844 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6846 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6848 On assertion failure, print backtrace if available.
6849 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6850 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6851 * Makefile.in (LIB_EXECINFO): New macro.
6854 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6855 * bytecode.c (exec_byte_code):
6856 * callint.c (check_mark, Fcall_interactively):
6857 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6858 (getenv_internal, sync_process_alive, call_process_exited):
6859 * lisp.h (USE_SAFE_ALLOCA):
6860 Use bool for booleans, instead of int.
6861 * lisp.h, process.h: Adjust prototypes to match above changes.
6862 * callint.c (Fcall_interactively): Don't assume the mark's
6863 offset fits in 'int'.
6865 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6867 * buffer.c, buffer.h: Use bool for boolean.
6868 * buffer.c (reset_buffer_local_variables)
6869 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6870 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6871 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6872 (overlay_touches_p, overlay_strings, Foverlay_put)
6873 (report_overlay_modification, call_overlay_mod_hooks):
6874 (mmap_enlarge, mmap_set_vars):
6875 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6876 Use bool for booleans, instead of int.
6877 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6878 since the 1-or-0 return value is always ignored anyway.
6879 (mmap_initialized_p):
6880 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6881 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6883 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6885 * bidi.c: Use bool for boolean.
6886 This is a bit more readable, and makes the text segment of bidi.o
6887 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6888 Presumably it's faster too.
6889 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6891 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6892 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6893 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6894 (bidi_explicit_dir_char, bidi_level_of_next_char)
6895 (bidi_find_other_level_edge, bidi_move_to_visually_next):

6897 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6898 (bidi_unshelve_cache): Adjust decls to match code.
6900 2012-08-23 Martin Rudalics <rudalics@gmx.at>

6907 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6908 * atimer.h: Include <stdbool.h>.
6910 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6912 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6913 compile time tests instead of run time tests on systems that do
6915 (FRAME_MAC_P): Remove leftover from deleted code.
6916 * frame.c (syms_of_frame): Remove leftover from deleted code.
6918 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6922 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6924 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6925 Otherwise, the compiler complains about (A?B:C) where B is void
6926 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6927 (fontset_add): Return void, for FONTSET_ADD.
6929 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6931 * alloc.c: Use bool for booleans.
6932 (gc_in_progress, abort_on_gc)
6933 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6934 (dont_register_blocks) [GC_MALLOC_CHECK]:
6935 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6936 (check_string_bytes, make_specified_string, memory_full)
6937 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6938 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6939 (mark_stack, valid_pointer_p, make_pure_string)
6940 (Fgarbage_collect, survives_gc_p, gc_sweep):
6941 Use bool for booleans, instead of int.
6942 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6943 Remove unused local.
6944 * alloc.c (PURE_POINTER_P):
6945 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6946 * editfns.c (Fformat):
6947 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6949 * fns.c (sweep_weak_table):
6950 * lisp.h (suppress_checking, push_message, survives_gc_p)
6951 (make_pure_string, gc_in_progress, abort_on_gc):
6952 * lread.c (readchar, read1):
6953 * print.c (Fprin1_to_string):
6954 * xdisp.c (push_message):
6955 Use bool for booleans affected directly or indirectly by
6958 Make recently-introduced setters macros.
6959 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6960 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6961 (set_fontset_default, set_fontset_fallback): Rename from their
6962 upper-case counterparts, and make them functions rather than macros.
6963 This is more consistent with the other recently-introduced setters.
6964 These don't need to be inline, since they're local.
6966 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6968 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6969 the loop (Bug#12247).
6971 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6973 * lisp.h (vcopy): Use memcpy rather than our own loop.
6974 This fixes a performance regression introduced by the recent
6975 addition of vcopy. This means 'vcopy' will need to be modified
6976 for a copying collector, but that's OK. Also, tighten the
6977 checking in the assertion.
6979 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6981 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6982 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6983 non-base glyph for the width of the base character, according to
6984 what x_draw_composite_glyph_string_foreground expects.
6985 Generate WADJUST value according to composition_gstring_width's
6986 expectations, to produce correct width of the composed character.
6987 Reverse the sign of the DU offset produced by ScriptPlace.
6989 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6991 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6993 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6995 Avoid direct writes to contents member of struct Lisp_Vector.
6996 * lisp.h (vcopy): New function to copy data into vector.
6997 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6998 * fns.c (Ffillarray): Use ASET.
6999 * keyboard.c (timer_check_2): Use AREF and ASET.
7000 (append_tool_bar_item, Frecent_keys): Use vcopy.
7001 * lread.c (read_vector): Use ASET.
7002 * msdos.c (Frecent_doskeys): Use vcopy.
7003 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7004 (Finternal_merge_in_global_face): Use ASET and vcopy.

7010 the position of its buffer's point.
7011 (Fset_window_point): For the selected window always go in its
7012 buffer to the specified position.
7014 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7016 Setter macros for fontsets.
7017 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7018 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7019 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7022 2012-08-20 Glenn Morris <rgm@gnu.org>
7024 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7025 Don't assume that `ln -f' works.
7027 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7029 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7030 and later about non-assignments with no effect. See discussion at
7031 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7034 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7036 Inline setter functions for Lisp_Objects slots of struct specbinding.
7037 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7040 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7042 * window.c (select_window): Always make selected window's buffer
7045 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7047 Use AREF and ASET for docstrings of category tables.
7048 * category.h (CATEGORY_DOCSTRING): Use AREF.
7049 (SET_CATEGORY_DOCSTRING): Use ASET.
7050 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7052 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7054 Inline setter functions for hash table members.
7055 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7056 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7057 (set_hash_key_and_value, set_hash_index, set_hash_next)
7058 (set_hash_hash): New functions.
7059 * charset.c, fns.c: Adjust users.
7061 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7063 Inline getter and setter functions for per-buffer values.
7064 * buffer.h (per_buffer_default, set_per_buffer_default)
7065 (per_buffer_value, set_per_buffer_value): New functions.
7066 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7067 * buffer.c, data.c: Adjust users.
7069 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7071 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7073 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7075 Rely on <config.h> + <unistd.h> to declare 'environ',
7076 as gnulib does this if the system doesn't.
7077 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7078 Remove declaration. MS-Windows declares it on stdlib.h which is
7079 included by conf_post.h.
7080 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7081 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7082 * vm-limit.c: Include <unistd.h>, for 'environ'.
7084 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7085 (start_of_data): Remove decl; mem-limits.h provides it.
7087 * xdisp.c (handle_invisible_prop): Make it a bit faster
7088 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7090 2012-08-19 Chong Yidong <cyd@gnu.org>
7092 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7095 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7097 * .gdbinit: Use call instead of set when calling a function in the
7100 * data.c (set_internal): Don't use set_blv_found.
7101 (Fkill_local_variable): Likewise.
7103 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7105 * nsfont.m (ns_ascii_average_width): Ensure the string
7106 ascii_printable is initialized with a null-terminated character
7107 array. Otherwise, it can contain undesired extra characters.
7109 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7111 port new setting code to Sun C 5.8 2005/10/13
7112 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7113 Return void, not Lisp_Object. Otherwise, the compiler
7114 complains about (A?B:C) where B is void and C is Lisp_Object
7115 when compiling CHAR_TABLE_SET, due to the recent change to
7116 the API of sub_char_table_set_contents.
7118 2012-08-18 Chong Yidong <cyd@gnu.org>
7120 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7121 for the string case (Bug#3874).

7949 * w32.c (init_environment): Change the default values of many
7950 environment variables in dflt_envvars[] to NULL, to avoid pushing
7951 them into environment when they were not already defined.
7952 Remove the code that deletes site-lisp subdirectories from the default
7953 value of EMACSLOADPATH, as it is no longer needed.
7954 (check_windows_init_file): Now external, not static.
7955 Use Vload_path as is, without adding anything, as this function is now
7956 called when Vload_path is already set up.
7958 * w32.h (check_windows_init_file): Add prototype.
7960 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8004 Remove unnecessary pointer casts.
8005 * alloc.c (record_xmalloc): New function.
8006 * lisp.h (record_xmalloc): New decl.
8007 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8008 more like a function. This is because the pointer cast is not
8009 needed. All uses changed.
8010 * print.c (print_string, print_error_message): Avoid length recalc.
8012 Improve fix for macroexp crash with debugging (Bug#12118).
8013 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8014 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8015 not supposed to be invoked from the garbage collector.

8017 (gc_aset): New function, which is like ASET but can be
8018 used in the garbage collector.

8047 with addition of handling of symlinks and support for 'lstat'.
8048 If possible, get file's attributes and security information by
8049 handle, not by name. Produce S_IFLNK bit for symlinks, when
8050 called from 'lstat'.
8051 (stat, lstat): New functions, call 'stat_worker'.
8052 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8053 symlinks when the underlying filesystem supports them.
8055 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8057 Fix macroexp crash on Windows with debugging (Bug#12118).
8058 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8059 checking subscripts; problem introduced with the recent
8060 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8061 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8062 since it's used in non-static inline functions now.
8064 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8065 Don't assume buffer size fits in 'int'. Remove unused local.

8086 * dispnew.c (DISPEXTERN_INLINE):
8087 * sysdep.c (SYSTIME_INLINE):
8088 Define to EXTERN_INLINE, so that the corresponding functions
8089 are compiled into code.

8091 (INLINE_HEADER_END): New macros.
8092 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8112 hard-coding the path separator.
8114 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8116 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8117 This how ASET and AREF are supposed to work, and makes
8118 it easier to think about future improvements. See
8119 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8120 * charset.h (set_charset_attr): New function.

8609 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8610 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8611 emacs.c, as this is a more-suitable home. Had this been done earlier
8612 the fix for 12036 would have avoided some of the problems noted in
8613 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8614 would have been more obvious.
8615 * emacs.c: Do not include <verify.h>; no longer needed.
8616 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8617 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8618 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8619 Remove; now done in lisp.h.
8620 * lisp.h (PUBLISH_TO_GDB): New macro.
8621 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8622 (DATA_SEG_BITS): Use it.
8623 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8624 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8625 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8626 not be usable in #if. This simplifies things.
8628 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8630 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8632 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

8635 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8636 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8637 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8638 Adjust to changes in lisp.h and emacs.c, by using
8639 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8640 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8641 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8642 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8643 instead of gdb_valbits.
8644 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8645 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8646 instead of gdb_array_mark_flag.
8647 (xboolvector): Get size from $->size, not $->header.size.
8648 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8649 (xreload, hook-run, hookpost-run): Remove.
8650 * emacs.c: Include <verify.h>.
8651 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8652 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8654 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8655 (gdb_USE_LSB_TAG): New enum constants.
8656 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8657 Also define these as enum constants, so they're visible to GDB.
8658 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8659 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8660 as constants, so they're visible to GDB.

8662 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8663 Now enum constants, not macros, so they're visible to GDB.
8664 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8665 more convenient now. All uses changed.
8666 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8667 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8669 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
8671 Explicitly free restriction data that are not needed anymore.

8674 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8676 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8677 add argument, tune behavior, and adjust all callers.
8679 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8681 Use typedef for EMACS_INT, EMACS_UINT.
8682 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8683 than macros. This simplifies debugging in the usual case, since
8684 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8685 and it allows expressions involving EMACS_INT casts.
8686 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8688 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8698 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8700 Adjust buffer text indirection counters at the end of Fkill_buffer.
8701 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8702 buffer is definitely dead. This should really fix an issue reported
8703 by Christoph Scholtes again. (Bug#12007).
8704 (init_buffer_once): Initialize indirection counters of
8705 buffer_defaults and buffer_local_symbols (for sanity and safety).
8707 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8709 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8710 and continuation glyphs on tooltip frames, leave them at zero.
8711 Avoids continued lines in tooltips. (Bug#11832)
8713 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8715 Simplify copy_overlay.

8738 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8740 Swap buffer text indirection counters in Fbuffer_swap_text.
8741 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8742 This avoids crash reported by Christoph Scholtes at
8743 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8745 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8747 * nsmenu.m (Popdown_data): New struct.

8752 and autorelease them. Also autorelease img and matrix (Bug#12005).
8753 (dealloc): Remove (Bug#12005).

8770 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8772 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8773 as it's limited by the amount of memory, not by INT_MAX.
8775 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8777 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8778 in special-event-map. See the discussion at

8859 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8860 'for_each_per_buffer_object_at'.

8913 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8915 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

8928 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8930 * eval.c (Fdefvar): Don't check constants since we only set the var if
8931 it's not yet defined anyway (bug#11904).
8933 * lisp.h (last_undo_boundary): Declare new var.
8934 * keyboard.c (command_loop_1): Set it.
8935 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8936 were auto-added by the command loop (bug#11774).
8938 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

9498 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
9500 Remove "#define unix" that is no longer needed (Bug#11905).
9501 * s/aix4-2.h (unix): Remove; no longer needed.
9503 EMACS_TIME simplification (Bug#11875).
9504 This replaces macros (which typically do not work in GDB)
9505 with functions, typedefs and enums, making the code easier to debug.
9506 The functional style also makes code easier to read and maintain.
9507 * systime.h: Include <sys/time.h> on all hosts, not just if
9508 WINDOWSNT, since 'struct timeval' is needed in general.
9509 (EMACS_TIME): Now a typedef, not a macro.
9510 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9512 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
9513 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
9514 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9515 (EMACS_TIME_LE): Now functions, not macros.
9516 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9517 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9518 which are not functions. All uses rewritten to use:
9519 (make_emacs_time): New function.
9520 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9521 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9522 not functions. All uses rewritten to use the following, respectively:
9523 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9524 (add_emacs_time, sub_emacs_time): New functions.
9525 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9526 * fileio.c (Fcopy_file):
9527 * xterm.c (XTflash): Get the current time closer to when it's used.
9528 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
9530 * bytecode.c (targets): Suppress -Woverride-init warnings.
9532 Simplify by avoiding confusing use of strncpy etc.
9533 * doc.c (Fsnarf_documentation):
9534 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
9535 * frame.c (Fmake_terminal_frame):
9536 * gtkutil.c (get_utf8_string):
9538 * nsmenu.m (ns_update_menubar):
9539 * regex.c (regerror):
9540 Prefer memcpy to strncpy and strncat when either will do.
9541 * fileio.c (Fsubstitute_in_file_name):
9542 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9543 (menu_separator_name_p):
9544 * nsmenu.m (ns_update_menubar):
9545 Prefer memcmp to strncmp when either will do.
9546 * nsterm.m: Include <ftoastr.h>.
9548 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9549 Prefer snprintf to strncpy.
9550 * nsterm.m (ns_term_init):
9551 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9552 * nsterm.m (ns_term_init):
9553 Avoid the need for strncpy, by using build_string or
9554 make_unibyte_string directly. Use dtoastr, not snprintf.
9555 * process.c (Fmake_network_process): Diagnose service names that
9556 are too long, rather than silently truncating them or creating
9557 non-null-terminated names.
9558 (Fnetwork_interface_info): Likewise, for interface names.
9559 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9560 Prefer sprintf to strncat.
9561 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9562 Prefer vsnprintf to vsprintf + strncpy.
9564 2012-07-10 Glenn Morris <rgm@gnu.org>
9566 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9567 Clarify fallback case.
9569 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9571 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9572 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9573 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9574 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9575 where argument type is known to be a Lisp_Cons.
9577 2012-07-10 Tom Tromey <tromey@redhat.com>
9579 * bytecode.c (BYTE_CODE_THREADED): New macro.
9580 (BYTE_CODES): New macro. Replaces all old byte-code defines.
9581 (enum byte_code_op): New type.
9582 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
9583 (exec_byte_code): Use them. Use token threading when applicable.
9585 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9587 Optimize pure C strings initialization.
9588 * lisp.h (make_pure_string): Fix prototype.
9589 (build_pure_c_string): New function, defined as static inline. This
9590 provides a better opportunity to optimize away calls to strlen when
9591 the function is called with compile-time constant argument.
9592 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9593 argument, adjust users accordingly. Use build_pure_c_string where
9595 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9596 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9597 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9599 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9601 Avoid calls to strlen in miscellaneous functions.
9602 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9603 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9604 * lread.c (openp): Likewise.
9606 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9608 Avoid calls to strlen in path processing functions.
9609 * fileio.c (file_name_as_directory): Add comment. Change to add
9610 srclen argument and return the length of result. Adjust users
9612 (directory_file_name): Fix comment. Change to add srclen argument,
9613 swap 1st and 2nd arguments to obey the common convention.
9614 Adjust users accordingly.
9615 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9617 2012-07-10 Glenn Morris <rgm@gnu.org>
9619 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9620 Move PENDING_OUTPUT_COUNT definition to configure.
9622 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9623 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9624 * s/gnu.h (DATA_START): Move definitions to configure.
9626 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9627 We include usg5-4-common.h, which defines them both.
9629 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9630 O_RDONLY already includes it).
9632 Stop ns builds setting the EMACSLOADPATH environment variable.
9633 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9634 Now it does not set EMACSLOADPATH, just returns the load-path string.
9635 * nsterm.h: Update accordingly.
9636 * lread.c [HAVE_NS]: Include nsterm.h.
9637 (init_lread) [HAVE_NS]: Use ns_load_path.
9638 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9640 2012-07-09 Glenn Morris <rgm@gnu.org>
9642 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9643 since the included bsd-common.h does so.
9645 Stop ns builds setting the EMACSPATH environment variable.
9646 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9647 (ns_init_paths): Do not set EMACSPATH.
9648 * nsterm.h (ns_exec_path): Add it.
9649 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9652 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9654 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9656 * process.c (wait_reading_process_output): 'waitchannels' was unset
9657 when read_kbd || !NILP (wait_for_cell); fix this.
9659 Add GCC-style 'const' attribute to functions that can use it.
9660 * character.h (char_resolve_modifier_mask):
9661 * keyboard.h (make_ctrl_char):
9662 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9663 (init_character_once, next_almost_prime, init_fns, init_image)
9664 (flush_pending_output, init_sound):
9665 * mem-limits.h (start_of_data):
9666 * menu.h (finish_menu_items):
9667 Add ATTRIBUTE_CONST.

9669 Declare the dummy function with ATTRIBUTE_CONST.
9670 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9671 Add decls with ATTRIBUTE_CONST.
9673 Minor improvements to make_formatted_string.
9674 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9675 where int is good enough, as vsprintf returns an int.
9676 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9678 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9680 Use make_formatted_string to avoid double length calculation.
9681 * lisp.h (make_formatted_string): New prototype.
9682 * alloc.c (make_formatted_string): New function.
9683 * buffer.c (Fgenerate_new_buffer_name): Use it.
9684 * dbusbind.c (syms_of_dbusbind): Likewise.
9685 * editfns.c (Fcurrent_time_zone): Likewise.
9686 * filelock.c (get_boot_time): Likewise.
9687 * frame.c (make_terminal_frame, set_term_frame_name)
9688 (x_report_frame_params): Likewise.
9689 * image.c (gs_load): Likewise.
9690 * minibuf.c (get_minibuffer): Likewise.
9691 * msdos.c (dos_set_window_size): Likewise.
9692 * process.c (make_process): Likewise.

9696 2012-07-09 Glenn Morris <rgm@gnu.org>
9698 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
9699 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
9700 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
9701 * nsterm.h (ns_etc_directory): Add it.
9702 * callproc.c [HAVE_NS]: Include nsterm.h.
9703 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
9705 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9707 Move marker debugging code under MARKER_DEBUG.
9708 * marker.c (MARKER_DEBUG): Move marker debugging code under
9709 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9710 for bootstrap with --enable-checking (~3x slowdown reported
9711 by Juanma Barranquero <lekktu@gmail.com>).
9712 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9714 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9716 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9717 See <http://bugs.gnu.org/11825#29>.
9719 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9721 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9722 has no font, use the frame's font. (Bug#11813)
9723 (display_line): Add commentary about displaying truncation glyphs
9725 (produce_special_glyphs): Move here from term.c.
9727 * term.c (produce_special_glyphs): Move to xdisp.c.
9729 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9732 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9734 * xdisp.c (display_line): Avoid warning about implicit declaration
9737 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9739 * lisp.h: Remove empty conditional.
9741 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9743 * lread.c (load_path_check): Now static.
9745 Fix some minor --with-ns problems found by static checking.
9746 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9747 (x_set_font) [!HAVE_X_WINDOWS]:
9748 * image.c (xpm_load_image) [HAVE_NS]:
9749 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9750 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9751 Remove unused local.
9752 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9753 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9754 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9755 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9756 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9757 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9758 Fix pointer signedness problem.
9759 * xfaces.c (FRAME_X_FONT_TABLE):
9760 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9762 2012-07-07 Glenn Morris <rgm@gnu.org>
9764 * lread.c (load_path_check): New function, split from init_lread.
9765 (init_lread): Reorganize. Motivation:
9766 If EMACSLOADPATH is set, check/warn about that rather than the
9767 defaults, which we are not going to use. Hence we can remove
9768 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9769 Don't warn if site-lisp directories are missing.
9770 If not installed, start from a blank load-path, since
9771 PATH_LOADSEARCH refers to the eventual installation directories.
9773 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9775 Support truncation and continuation glyphs on GUI frames, when
9776 fringes are disabled. (Bug#11832)
9777 * xdisp.c (init_iterator): Get dimensions of truncation and
9778 continuation glyphs even if on GUI frames.
9779 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9780 or both, are absent.
9781 (start_display, move_it_in_display_line_to): Handle the case of a
9782 GUI frame without a fringe to display continuation or truncation
9784 (insert_left_trunc_glyphs): Support GUI frames: make sure
9785 truncation glyphs overwrite enough glyphs from the current line to
9786 have sufficient space in pixels.
9787 (display_line): Support truncation and continuation glyphs on GUI
9788 frames. If some spare pixels are left on the line after inserting
9789 the truncation glyphs, fill that space with a stretch glyph of a
9790 suitably computed width.
9792 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9793 produce_glyphs, to support GUI sessions.
9795 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9797 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9799 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9801 Do not require float-time's arg to fit in time_t (Bug#11825).
9802 This works better on hosts where time_t is unsigned, and where
9803 float-time is applied to the (negative) difference between two times.
9804 * editfns.c (decode_time_components): Last arg is now double *,
9805 not int *, and means to store all the result as a double, without
9806 worrying about whether the seconds part fits in time_t.
9807 All callers changed.
9808 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9809 All callers changed.
9810 (Ffloat_time): Do not fail merely because the specified time falls
9811 outside of time_t range.
9813 2012-07-07 Glenn Morris <rgm@gnu.org>
9815 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9816 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9817 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9819 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9821 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9822 Update dependencies.
9824 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9826 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9828 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9829 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9830 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9831 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9832 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9833 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9835 * xfont.c (compare_font_names): Redo to omit the need for casts.
9837 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9839 * xfns.c (Fx_change_window_property): Doc fix.
9840 * w32fns.c (Fx_change_window_property): Doc fix.
9842 * w32fns.c (Fx_window_property): Accept the same arguments as the
9843 X Windows version. Doc fix.
9844 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9846 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9847 Eli Zaretskii <eliz@gnu.org>
9849 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9850 Windows-specific code from nt/config.nt moved here.
9851 Obsolete settings removed.
9853 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9855 * process.c: Avoid unnecessary calls to gettime.
9856 (wait_reading_process_output): Don't get the time of day
9857 when gobbling data immediately and not waiting, as there's no need
9858 for it in that case. This removes a FIXME.
9860 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9862 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9863 is defined (Bug#11768).
9865 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9867 Fix marker debugging code.
9868 * marker.c (byte_char_debug_check): Do not perform the check
9869 if buffer is not multibyte.
9870 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9871 Call byte_char_debug_check with correct arguments.
9873 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9875 Compile marker debugging code only if ENABLE_CHECKING is defined.
9876 * marker.c (byte_char_debug_check, count_markers):
9877 Use only if ENABLE_CHECKING is defined.
9878 (byte_debug_flag): Remove.
9879 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9880 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9882 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9884 Avoid code repetition in marker-related functions.
9885 * marker.c (attach_marker): New function.
9886 (Fset_marker, set_marker_restricted, set_marker_both)
9887 (set_marker_restricted_both): Use it.
9888 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9889 Consistently rename charno to charpos.
9890 (marker_position): Add eassert.
9891 (marker_byte_position): Convert to eassert.
9893 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9895 Simplify list operations in unchain_overlay and unchain_marker.
9896 * buffer.c (unchain_overlay): Simplify. Add comment.
9897 * marker.c (unchain_marker): Simplify. Fix comments.
9899 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9901 Introduce fast path for the widely used marker operation.
9902 * alloc.c (build_marker): New function.
9903 * lisp.h (build_marker): New prototype.
9904 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9905 * composite.c (autocmp_chars): Likewise.
9906 * editfns.c (buildmark): Remove.
9907 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9908 (save_restriction_save): Use build_marker.
9909 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9910 * window.c (save_window_save): Likewise.
9912 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9914 Do not use Fdelete_overlay in delete_all_overlays
9915 to avoid redundant calls to unchain_overlay.
9916 * buffer.c (drop_overlay): New function.
9917 (delete_all_overlays, Fdelete_overlay): Use it.
9918 * minibuf.c (get_minibuffer): Fix comment.
9920 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9922 Port to OpenBSD 5.1 amd64.
9923 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9924 This is needed for OpenBSD, and should be harmless on all BSD systems.
9925 Also, include <sys/sysctl.h>, as it should be available on all
9926 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9927 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9928 use p_pid member, not kp_proc.pid.
9930 2012-07-06 Glenn Morris <rgm@gnu.org>
9932 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9934 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9947 Omit needless casts involving void * pointers and allocation.
9948 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9949 as the former is more robust if P's type is changed.
9950 Prefer xzalloc to xmalloc + memset 0.
9951 Simplify malloc-or-realloc to realloc.
9952 Don't worry about xmalloc returning a null pointer.
9953 Prefer xstrdup to xmalloc + strcpy.
9954 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9956 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9957 alloca of a constant.
9959 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9961 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9962 hscroll is larger than the line width. Fixes long and futile
9963 looping inside extend_face_to_end_of_line (on a TTY) producing
9964 glyphs that are not needed and thrown away.
9966 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9968 * marker.c (set_marker_restricted_both): Simplify by using

9989 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9990 with default display (Bug#11768).
9992 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9994 * xdisp.c (window_hscroll_limited): New function.
9995 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9996 coordinates when window's hscroll is set to insanely large

10063 Problem reported by Troels Nielsen in
10064 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10066 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10068 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10069 This should be fixed in a better way; see Eli Zaretskii in
10070 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10071 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10073 * fileio.c (time_error_value): Rename from special_mtime.
10074 The old name's problems were noted by Eli Zaretskii in
10075 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10077 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10078 This variable's comment says Emacs needs at least one GDB-visible
10079 symbol of type enum pvec_type, to work around GDB problems.
10080 The symbol's value doesn't matter.
10082 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10083 that causes compilation to fail on pre-C99 compilers.
10085 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10087 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10092 * buffer.c (init_buffer_once): Fix initialization of
10093 headers for buffer_defaults and buffer_local_symbols.
10094 Reported by Juanma Barranquero <lekktu@gmail.com>.
10096 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10098 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.

10100 (PSEUDOVECTOR_SIZE_BITS): New constant.
10101 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10102 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10103 change in pvec_type.
10104 (PSEUDOVECTOR_TYPEP): New macro.
10105 (TYPED_PSEUDOVECTORP): Use it.
10106 * fns.c (internal_equal): Adapt code to extract pvectype.
10107 * emacs.c (gdb_pvec_type): Update type.
10108 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10109 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10110 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10111 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10112 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10113 abusing vector->header.next.nbytes.
10114 (live_vector_p): Use PVEC_TYPE.
10115 (mark_object): Adapt code to extract pvectype. Use switch.
10117 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10119 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10120 Tighten new eassert a bit.
10122 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10124 Fix compilation with --enable-gcc-warnings and -O1
10125 optimization level.
10126 * doprnt.c (doprnt): Change type of tem to int, initialize
10127 to avoid compiler warning. Add eassert.
10128 * search.c (simple_search): Initialize match_byte to avoid
10129 compiler warning. Add eassert.
10131 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10133 Avoid weird behavior with large horizontal scrolls.
10134 Without this change, for example, large hscroll values would
10135 mess up Emacs's display on Fedora 15 x86, presumably due to
10136 overflows in int calculations in the display code.
10137 Also, if buffers had long lines, Emacs would freeze.
10138 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10139 (set_window_hscroll): New function, containing the old guts of
10140 Fset_window_hscroll. Return the clipped value.
10141 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10142 This avoids the need to check against PTRDIFF_MAX.
10144 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10146 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10148 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10150 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10152 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10153 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10154 since GCC 4.4.6 issues a bogus warning for them.
10156 Fix bugs in file timestamp newness comparisons.
10157 * fileio.c (Ffile_newer_than_file_p):
10158 * lread.c (Fload): Use full timestamp resolution of files,
10159 not just the 1-second resolution, so that files that are only
10160 slightly newer still count as newer.
10161 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10162 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10164 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10166 * fileio.c: Improve handling of file time marker. (Bug#11852)
10167 (special_mtime): New function.
10168 (Finsert_file_contents, Fverify_visited_file_modtime):
10169 Use it to set special mtime values consistently.
10171 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10173 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10174 marker for non-existing file. (Bug#11852)
10176 2012-07-03 Glenn Morris <rgm@gnu.org>
10178 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10179 and did not make it into globals.h).
10181 2012-07-03 Tom Tromey <tromey@redhat.com>
10183 * window.c (Fset_window_margins, Fset_window_fringes)

10210 * font.h: Remove EXFUNs.
10211 * dosfns.c (system_process_attributes): Remove EXFUN.
10212 * keymap.h: Remove EXFUNs.
10213 * lisp.h: Remove EXFUNs.
10214 * w32term.h: Remove EXFUNs.
10215 * window.h: Remove EXFUNs.
10216 * xsettings.h: Remove EXFUN.
10217 * xterm.h: Remove EXFUN.
10219 2012-07-03 Glenn Morris <rgm@gnu.org>
10221 * lisp.h (Frandom): Make it visible to C.
10222 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10223 buffer for invisible buffers. (Bug#1229)
10225 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10227 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10228 values which aren't power of 2.
10229 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10230 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10233 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10235 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10237 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10239 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10241 * alloc.c (allocate_vector_block): Remove redundant
10242 calls to mallopt if DOUG_LEA_MALLOC is defined.
10243 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10244 avoid calls to mallopt if zero_vector is returned.
10246 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10248 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10249 is enabled, avoid dereferencing NULL current_sblock if
10252 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10254 Cleanup basic buffer management.
10255 * buffer.h (struct buffer): Change layout to use generic vector
10256 marking code. Fix some comments. Change type of 'clip_changed'
10257 to bitfield. Remove unused #ifndef old.
10258 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10259 (GET_OVERLAYS_AT): Fix indentation.
10260 (for_each_per_buffer_object_at): New macro.
10261 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

10265 struct buffer. Fix comment.
10266 (mark_overlay): New function.
10267 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10268 Lisp area of struct buffer.
10269 (mark_object): Use it. Adjust marking of misc objects
10270 and related comments.
10272 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10274 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10275 wrapper that is not needed because the wrapped code is a no-op (zero
10276 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10277 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10279 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10281 * alloc.c (mark_buffer): Simplify. Remove prototype.
10282 (mark_object): Add comment. Reorganize marking of vector-like
10283 objects. Use CHECK_LIVE for all vector-like objects except buffers
10284 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10285 Avoid redundant calls to mark_vectorlike for bool vectors.
10287 2012-06-30 Glenn Morris <rgm@gnu.org>
10289 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10291 * epaths.in (PATH_SITELOADSEARCH): New.
10292 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10293 This is rather than relying on --enable-locallisppath elements
10294 having "site-lisp" in their names. (Bug#10208#25, 11658)
10296 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10298 * w32proc.c (sys_select): Accept and ignore one more argument.
10300 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10302 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10303 (pselect) [!MS_DOS]: Redirect to sys_select.
10305 * sysdep.c: Don't include dos.h and dosfns.h.
10307 * process.c (sys_select):
10308 * msdos.c (sys_select): Accept one more argument and ignore it.
10310 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10311 adapt data types and code to that.
10314 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10315 which clashes with the gnulib function of the same name.
10317 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10319 * font.c (font_style_to_value, font_style_symbolic)
10320 (font_prop_validate_style): Add type checks for values in
10323 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10325 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10328 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10330 * xdisp.c (try_window_id): Undo last change.
10332 * w32.c (getwd): Adjust commentary about startup_dir.
10333 (init_environment): Always call sys_access, even in non-MSVC
10334 builds. Don't chdir to the directory of the Emacs executable.
10335 This undoes code from 1997 which was justified by the need to
10336 "avoid conflicts when removing and renaming directories". But its
10337 downside was that every relative file name was being interpreted
10338 relative to the directory of the Emacs executable, which can never
10339 be TRT. In particular, it broke sys_access when called with
10340 relative file names.
10341 (sys_access): Map GetLastError to errno.
10343 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10345 * window.h (struct window): Change type of 'fringes_outside_margins'
10346 to bitfield. Fix comment. Adjust users accordingly.
10347 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10349 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10352 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10354 * gnutls.c (emacs_gnutls_handshake):
10355 Add QUIT to make the loop interruptible.
10357 2012-06-29 Glenn Morris <rgm@gnu.org>
10359 * charset.c (init_charset): Make lack of etc/charsets fatal.
10361 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10363 * editfns.c (region_limit): Fix type mismatch.
10365 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10367 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10368 undefined. Convert from xassert to eassert.
10369 * nsmenu.m: Convert from xassert to eassert.
10370 * nsterm.m: Likewise.
10372 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10374 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10376 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10378 Avoid integer overflow on scroll-left and scroll-right.
10379 * window.c (HSCROLL_MAX): New macro.
10380 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10381 overflow when requested scroll falls outside ptrdiff_t range.
10383 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10385 * window.h (struct window): Change type of 'hscroll',
10386 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10387 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10388 Adjust users accordingly.
10389 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10390 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'

10535 Use sprintf return value instead of invoking strlen on result.
10536 In the old days this wasn't portable, since some sprintf
10537 implementations returned char *. But they died out years ago and
10538 Emacs already assumes sprintf returns int.
10539 Similarly for float_to_string.
10540 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10548 Use sprintf or float_to_string result to avoid need to call strlen.
10549 * data.c (Fnumber_to_string):
10550 Use make_unibyte_string, since the string must be ASCII.
10551 * lisp.h, print.c (float_to_string): Now returns int length.
10552 * term.c (produce_glyphless_glyph):
10553 Use sprintf result rather than recomputing it.
10555 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10584 * xfns.c (x_window): Remove redundant cast.
10586 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10588 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10591 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10593 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10594 instead of truncating it to 63 (admittedly a generous limit).
10596 * process.c: Fix spelling and caps in comments.

10654 * keyboard.c (kbd_buffer_get_event):
10655 * process.c (Faccept_process_output):
10656 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10657 This improves on the previous patch, which introduced a bug
10658 when time_t is unsigned and as wide as intmax_t.
10659 See <http://bugs.gnu.org/9000#51>.
10661 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10690 language ID in the event parameters.
10692 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10693 event.code, not the obscure "character set ID".
10695 2012-06-23 Chong Yidong <cyd@gnu.org>

10724 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10726 Support higher-resolution time stamps (Bug#9000).
10727 The time stamps are only nanosecond-resolution at the C level,
10728 since that's the best that any real-world system supports now.
10729 But they are picosecond-resolution at the Lisp level, as that's
10730 easy, and leaves room for future OS improvements.
10732 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10735 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10736 Don't get current time unless it's needed.
10738 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10739 now provides it if it's absent.
10740 (start_atimer): Port to higher-res time stamps.
10741 Check for time stamp overflow. Don't get current time more
10742 often than is needed.
10744 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10745 Include systime.h, not time.h.
10746 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10748 * dired.c: Include stat-time.h.
10749 (Ffile-attributes): File times now have higher resolution.
10751 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10752 (struct image): Timestamp now has higher resolution.
10754 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10755 has at least microseconds now. All uses removed.
10756 (update_frame, update_single_window, update_window, update_frame_1)
10757 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10758 (duration_to_sec_usec): Remove; no longer needed.
10760 * editfns.c (time_overflow): Now extern.
10761 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10762 (float-time, Fformat_time_string, Fcurrent_time_string)

10766 (decode_time_components, lisp_seconds_argument): New functions.
10767 (make_time): Now static.
10768 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10769 Report an error if the time is invalid, rather than having the caller
10772 * fileio.c: Include <stat-time.h>
10773 (Fcopy_file): Copy higher-resolution time stamps.
10774 Prefer to set the time stamp via a file descriptor if that works.
10775 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10776 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10777 (Fvisited_file_modtime, Fset_visited_file_modtime):
10778 Support higher-resolution time stamps.
10780 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10782 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10784 * image.c (prepare_image_for_display, clear_image_cache)
10785 (lookup_image): Port to higer-resolution time stamps.
10787 * keyboard.c (start_polling, bind_polling_period):
10788 Check for time stamp overflow.
10789 (read_char, kbd_buffer_get_event, timer_start_idle)
10790 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10791 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10792 Port to higher-resolution time stamps. Do not assume time_t is signed.
10793 (decode_timer): New function. Timers are now vectors of length 9,
10794 not 8, to accommodate the picosecond component.
10795 (timer_check_2): Use it.
10797 * nsterm.m (select_timeout, timeval_subtract): Remove.
10798 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10799 as they're a bit more accurate and handle overflow better.
10800 (ns_select): Change prototype to be compatible with pselect.
10801 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10802 * nsterm.h (ns_select): Adjust prototype.
10804 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10805 us-resolution time stamps.
10806 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10808 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10810 * lisp.h (time_overflow): New decl.
10811 (wait_reading_process_output): First arg is now intmax_t, not int,
10812 to accommodate larger waits.
10814 * process.h (struct Lisp_Process.read_output_delay):
10815 Now counts nanoseconds, not microseconds.
10816 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10818 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10819 (wait_reading_process_output):
10820 Port to ns-resolution time stamps.
10821 (Faccept_process_output, wait_reading_process_output):
10822 Check for time stamp overflow. Do not assume time_t is signed.
10823 (select_wrapper): Remove; we now use pselect.
10824 (Fprocess_attributes): Now generates ns-resolution time stamps.
10826 * sysdep.c: Include utimens.h. Don't include utime.h
10827 or worry about struct utimbuf; gnulib does that for us now.
10828 (gettimeofday): Remove; gnulib provides a substitute.
10829 (make_timeval): New function.
10830 (set_file_times): Now sets ns-resolution time stamps.
10831 New arg FD; all uses changed.
10832 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10833 (system_process_attributes):
10834 Now returns ns-resolution time stamp. All uses changed.
10835 Check for time stamp overflow.
10837 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10838 provides a substitute now.
10840 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10841 since it guarantees struct timespec.
10842 (EMACS_TIME): Now struct timespec, so that we can support
10843 ns-resolution time stamps.
10844 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10845 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10846 (EMACS_USECS): Remove.
10847 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10848 so multiply the arg by 1000 before storing it.
10849 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10851 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10852 Port to ns-resolution time stamps.
10853 (EMACS_TIME_NEG_P): Remove; replaced by....

10858 (make_timeval, make_lisp_time, decode_time_components): New decls.
10859 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10860 that it mishandled time_t overflow. You can't compare by subtracting!
10861 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10862 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

10901 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10902 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10903 staticidx goes up to 1597 out of 1600 = 0x640.)
10905 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10907 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

10934 (prepare_menu_bars): Likewise.
10936 * term.c (Ftty_top_frame): New function.
10938 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10940 Port byte-code-meter to modern targets.
10941 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10942 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10943 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in

10953 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10954 gets killed during executing of this function (Bug#11665).
10955 Try to always return Qt when the buffer has been actually killed.

11300 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
11301 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
11302 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
11303 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
11304 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
11305 (roundup_size): New constant.
11306 (struct vector_block): New data type.
11307 (vector_blocks, vector_free_lists, zero_vector): New variables.

11310 (sweep_vectors): New functions.
11311 (allocate_vectorlike): Return `zero_vector' as the only vector of
11312 0 items. Allocate new vector from block if vector size is less than
11313 or equal to VBLOCK_BYTES_MAX.
11314 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
11315 (init_alloc_once): Add call to init_vectors.
11317 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11319 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11321 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11323 * doprnt.c (doprnt): Truncate multibyte char correctly.
11324 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11325 would mishandle a string argument "Xc" if X was a multibyte
11326 character of length 2: it would truncate after X's first byte
11327 rather than including all of X.
11329 2012-06-06 Chong Yidong <cyd@gnu.org>
11331 * buffer.c (word_wrap): Doc fix.
11333 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11345 binary via PaX flags if the paxctl utility is available.
11346 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11347 Restore PaX flags to their default. (Bug#11398)
11349 2012-06-03 Chong Yidong <cyd@gnu.org>
11351 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11352 buffer (Bug#11226).

11356 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
11357 (note_mode_line_or_margin_highlight): If there is no help echo,
11358 use mode-line-default-help-echo. Handle the case where the mouse
11359 position is past the end of the mode line string.
11361 * buffer.c (buffer_local_value_1): New function, split from
11362 Fbuffer_local_value; can return Qunbound.
11363 (Fbuffer_local_value): Use it.
11364 (Vmode_line_format): Docstring tweaks.
11366 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11368 * sysdep.c (system_process_attributes): Improve comment.
11370 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
11372 * keyboard.c: Export real-this-command to Elisp.
11373 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11374 and DEFVAR it. Update all users.
11376 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11378 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11380 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11381 Convert pctcpu and pctmem to Lisp float properly.
11382 Let the compiler fold better, as 100.0/0x8000 is exact.
11384 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11386 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11389 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11391 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11393 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11395 For a 'struct window', replace some Lisp_Object fields to
11396 bitfields where appropriate, remove unused fields.
11397 * window.h (struct window): Remove unused 'last_mark_x' and
11398 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11399 change its type from Lisp_Object to bitfield.
11400 Change type of 'force_start', 'optional_new_start',
11401 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11402 fields from Lisp_Object to bitfield. Adjust users accordingly.
11404 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11406 Pacify gcc -Wdouble-precision when using Xaw.
11407 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11408 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11409 Use 'float' consistently, rather than 'float' in most places
11410 and 'double' in a couple of places.
11412 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11414 * xdisp.c (handle_stop): Detect whether we have overlay strings
11415 loaded by testing it->current.overlay_string_index to be
11416 non-negative, instead of checking whether n_overlay_strings is
11417 positive. (Bug#11587)
11419 2012-05-31 Chong Yidong <cyd@gnu.org>
11421 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11423 * doc.c (Fsubstitute_command_keys): Doc fix.
11425 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11427 * search.c (search_buffer): Remove calls to
11428 r_alloc_inhibit_buffer_relocation, as it is now called by
11429 maybe_unify_char, which was the cause of relocation of buffer text
11432 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11434 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11435 for the duration of call to load_charset, to avoid problems with
11436 callers of maybe_unify_char that access buffer text through C
11439 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11440 decrement the inhibition flag, instead of just setting or
11443 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11445 Remove obsolete '#define static' cruft.
11446 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11447 This #undef was "temporary" in 2000; it is no longer needed
11448 now that '#define static' has gone away.
11449 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11450 (gray_bitmap_bits): Remove; no longer needed.
11451 All uses replaced with definiens.
11452 * xterm.c: Include "bitmaps/gray.xbm".
11454 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11456 Clean up __executable_start, monstartup when --enable-profiling.
11457 The following changes affect the code only when profiling.
11458 * dispnew.c (__executable_start): Rename from safe_bcopy.
11459 Define only on platforms that need it.
11460 * emacs.c: Include <sys/gmon.h> when profiling.
11461 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11462 (__executable_start): Remove decl, since lisp.h does it now.
11463 (safe_bcopy): Remove decl; no longer has that name.
11464 (main): Coalesce #if into single bit of code, for simplicity.
11465 Cast pointers to uintptr_t, since standard libraries want integers
11467 * lisp.h (__executable_start): New decl.
11469 2012-05-31 Glenn Morris <rgm@gnu.org>
11471 * image.c (Fimagemagick_types): Doc fix.
11473 2012-05-30 Jim Meyering <meyering@redhat.com>
11475 * callproc.c (Fcall_process_region): Include directory component

11488 (Qdefun): Move from eval.c.
11489 * lisp.h (Qdefun): Remove.
11490 * lread.c (read1): Tiny simplification.
11492 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11494 Do not create empty overlays with the evaporate property (Bug#9642).
11495 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11496 Bug#9642, but explicitly check that the buffer the overlay would
11497 be moved to is live and rearrange lines to make sure that errors
11498 will not put the overlay in an inconsistent state.
11499 (Fdelete_overlay): Cosmetics.
11501 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11503 * w32term.c (my_bring_window_to_top): New function.
11504 (x_raise_frame): Use handle returned by DeferWindowPos, which
11505 could be different from the original one.
11506 Call my_bring_window_to_top instead of my_set_foreground_window.
11509 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11510 by calling BringWindowToTop.

11515 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11517 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11518 This avoids undefined behavior that might cause the eassert
11519 to not catch an out-of-range value.
11521 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11523 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11524 Update dependencies.
11526 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11528 * bidi.c (bidi_mirror_char): Fix last change.
11530 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11533 when referring to sectname field in printf format.
11535 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11537 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11538 Only r_alloc_inhibit_buffer_relocation needed to be added;
11539 the others were already declared.
11541 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11542 before checking whether it's out of range. Put the check inside
11544 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11546 2012-05-27 Ken Brown <kbrown@cornell.edu>
11548 * callproc.c (Fcall_process): Restore a line that was accidentally
11549 commented out in the 2011-02-13 change (bug#11547).
11551 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11553 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11554 defined on ralloc.c.
11556 * buffer.c [REL_ALLOC]: Remove prototypes of
11557 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11558 they are now on lisp.h.
11560 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11562 * search.c (search_buffer): Use it to inhibit relocation of buffer
11563 text while re_search_2 is doing its job, because re_search_2 is
11564 passed C pointers to buffer text. (Bug#11519)
11566 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11567 Update value to 24.
11569 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11570 state after an additional call to move_it_in_display_line_to, keep
11571 the values of it->max_ascent and it->max_descent found for the
11573 (pos_visible_p): Revert the comparison against bottom_y to what it
11574 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11577 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11579 Fix coding-related core dumps with gcc -ftrapv.
11580 The code was computing A - B, where A and B are pointers, and B is
11581 random garbage. This can lead to core dumps on platforms that
11582 have special pointer registers, and it also leads to core dumps on
11583 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11584 A - B only when B is initialized properly.
11585 * coding.c (coding_set_source, coding_set_destination): Return void.
11586 (coding_change_source, coding_change_destinations): New functions,
11587 with the old behaviors of coding_set_source and coding_set_destination.
11588 All callers that need an offset changed to use these new functions.
11590 2012-05-26 Glenn Morris <rgm@gnu.org>
11592 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11594 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11596 Extend mouse support on W32 text-mode console.
11597 * xdisp.c (draw_row_with_mouse_face):
11598 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11600 * w32console.c: Include window.h.
11601 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11603 (initialize_w32_display): Initialize mouse-highlight data.
11605 * w32inevt.c: Include termchar.h and window.h.
11606 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11607 moves, call note_mouse_highlight. If help_echo changed, call
11608 gen_help_event to produce help-echo message in the echo area.
11609 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11612 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11614 * lread.c (read1): Simplify slightly to avoid an overflow warning
11615 with GCC 4.7.0 on x86-64.
11617 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11619 * bidi.c (bidi_mirror_char): Revert last change: an int is
11620 definitely wide enough here.
11622 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11624 Fix integer width and related bugs (Bug#9874).

11631 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11632 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11634 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11635 (allocate_pseudovector):
11636 Use int, not EMACS_INT, where int is wide enough.
11637 (inhibit_garbage_collection, Fgarbage_collect):
11638 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11639 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11640 int might not be wide enough.
11641 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11642 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11643 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11644 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11645 (bidi_level_of_next_char, bidi_move_to_visually_next):
11646 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11647 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11648 (Fkill_buffer, Fset_buffer_major_mode)
11649 (advance_to_char_boundary, Fbuffer_swap_text)

11656 (Foverlay_recenter, last_overlay_modification_hooks_used)
11657 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11658 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11659 (validate_region): Omit unnecessary test for b <= e,
11660 since that's guaranteed by the previous test.
11661 (adjust_overlays_for_delete): Avoid pos + length overflow.
11662 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11663 (report_overlay_modification):
11664 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11665 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11666 Omit pointer cast, which isn't needed anyway, and doesn't work
11667 after the EMACS_INT -> ptrdiff_t change.
11668 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11669 * buffer.h: Adjust decls to match defn changes elsewhere.
11670 (struct buffer_text, struct buffer):
11671 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11672 Use EMACS_INT, not int, where int might not be wide enough.
11673 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11674 not int, to avoid needless 32-bit limit on 64-bit hosts.
11675 (exec_byte_code): Use tighter memory-full test, one that checks
11676 for alloca overflow. Don't compute the address of the object just
11677 before an array, as that's not portable. Use EMACS_INT, not
11678 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11679 * callint.c (Fcall_interactively):
11680 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11681 * callproc.c (call_process_kill, Fcall_process):
11682 Don't assume pid_t fits into an Emacs fixnum.

11691 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11692 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11693 (casify_object): Avoid integer overflow when overallocating buffer.
11694 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11695 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11696 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11697 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11698 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11699 integers are now checked earlier. All uses replaced with XINT.
11701 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11702 For CCL_MapSingle, check that content and value are in int range.

11704 Check that Vcode_version_map_vector is a vector.
11705 (resolve_symbol_ccl_program): Check that vector header is in range.
11706 Always copy the vector, so that we can check its contents reliably
11707 now rather than having to recheck each instruction as it's being
11708 executed. Check that vector words fit in 'int'.
11709 (ccl_get_compiled_code, Fregister_ccl_program)
11710 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11711 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11712 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11713 contents are in range.
11714 (Fccl_execute_on_string): Check that status is in range.
11715 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11716 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11717 Accept and return EMACS_INT, not int, because callers can pass values
11718 out of 'int' range.

12394 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
12395 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12396 (Fx_change_window_property): Don't assume fixnums fit in int.
12397 * xfont.c (xfont_chars_supported):
12398 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12399 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
12400 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
12401 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12402 * xml.c (parse_region):
12403 * xrdb.c (magic_file_p):
12404 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12405 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
12406 (x_get_local_selection, x_reply_selection_request)
12407 (x_handle_selection_request, wait_for_property_change):
12408 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12409 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12410 short is wide enough.
12411 (x_send_client_event): Don't assume fixnum fits in int.
12412 * xterm.c (x_x_to_emacs_modifiers):
12413 Don't assume EMACS_INT overflows nicely into int.
12414 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12415 may come from Lisp.
12416 (handle_one_xevent): NATNUMP can eval its arg twice.
12417 (x_connection_closed):
12418 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12419 * xterm.h: Adjust decls to match defn changes elsewhere.
12420 (struct scroll_bar): Use struct vectorlike_header
12421 rather than rolling our own approximation.
12422 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12424 2012-05-25 Glenn Morris <rgm@gnu.org>
12426 * lisp.mk (lisp): Update for more files being compiled now.
12428 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12430 * lread.c: Remove `read_pure' which makes no difference.
12431 (read_pure): Remove var.
12432 (unreadpure): Remove function.
12433 (readevalloop): Don't call read_list with -1 flag.
12434 (read1, read_vector): Don't test read_pure any more.
12435 (read_list): Simplify.
12437 * fileio.c, character.h: Minor style tweaks.
12439 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12441 * window.h (clip_changed): Remove useless declaration.
12443 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12445 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12446 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12448 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12451 This directory predates autoconf and is no longer needed nowadays.
12452 Move its few remaining bits of functionality to where they're needed.
12453 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12454 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12455 * m/template.h: Remove.
12456 * Makefile.in (M_FILE): Remove. All uses removed.
12457 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12458 * lisp.h (USE_LSB_TAG):
12459 * mem-limits.h (EXCEEDS_LISP_PTR):
12460 Use VAL_MAX, not VALBITS, in #if.
12461 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12462 (EMACS_UINT): Define unconditionally now.
12463 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12464 (BITS_PER_EMACS_INT): New constants, replacing
12465 what used to be in config.h, but not useful in #if.
12466 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12467 define them any more.
12468 (VAL_MAX): New macro.
12470 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12471 BITS_PER_EMACS_INT, in #if.
12472 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12473 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12474 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12475 * s/ms-w32.h (DATA_START):
12476 Move here from removed file m/intel386.h.
12477 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12478 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12480 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12482 Assume C89 or later.
12483 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12484 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12486 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12487 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12488 * textprop.c, tparam.c (NULL): Remove.
12489 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12490 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12491 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12492 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12493 * xterm.c (input_signal_count): Assume volatile works.
12495 2012-05-21 Ken Brown <kbrown@cornell.edu>
12497 * xgselect.c (xg_select): Fix first argument in call to 'select'
12500 2012-05-20 Ken Brown <kbrown@cornell.edu>
12502 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12503 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12505 2012-05-19 Ken Brown <kbrown@cornell.edu>
12507 * xfns.c (x_in_use): Remove `static' qualifier.
12508 * xterm.h (x_in_use): Declare.
12509 * xgselect.c: Include xterm.h.
12510 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12511 and `display_arg' (bug#9754).
12513 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12515 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12517 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12518 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12520 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12522 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12524 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12525 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12527 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12528 reference to image_cache->refcount.
12529 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12531 2012-05-17 Juri Linkov <juri@jurta.org>
12533 * search.c (Fword_search_regexp, Fword_search_backward)
12534 (Fword_search_forward, Fword_search_backward_lax)
12535 (Fword_search_forward_lax): Move functions to isearch.el
12536 (bug#10145, bug#11381).
12538 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12540 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12542 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12544 * lread.c (init_obarray): Declare Qt and Qnil as special.
12546 2012-05-14 Glenn Morris <rgm@gnu.org>
12548 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12549 Put "libexec" before "bin", for the sake of init_callproc_1.
12551 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12553 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12555 * unexaix.c: Port to more-recent AIX compilers.
12556 (report_error, report_error_1, make_hdr, copy_sym)
12557 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12558 Make arguments const char *, not char *, to avoid violations of C
12559 standard and to fix some AIX warnings reported by Gilles Pion.
12561 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12563 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12564 already have overlays loaded.
12565 (handle_single_display_spec): Before returning without displaying
12566 fringe bitmap, synchronize the bidi iterator with the main display
12567 iterator, by calling iterate_out_of_display_property.
12568 (iterate_out_of_display_property): Detect buffer iteration by
12569 testing that it->string is a Lisp string.
12570 (get_next_display_element): When the current object is exhausted,
12571 and there's something on it->stack, call set_iterator_to_next to
12572 proceed with what's on the stack, instead of returning zero.
12573 (set_iterator_to_next): If called at the end of a Lisp string,
12574 proceed to consider_string_end without incrementing string
12575 position. Don't increment display vector index past the end of
12576 the display vector. (Bug#11417)
12577 (pos_visible_p): Don't report a position visible when move_it_to
12578 stopped at the last line of window, which happens to be scanned
12579 backwards by the bidi iteration. (Bug#11464)
12581 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12583 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12584 and right-margin display specs even if the spec is invalid or we
12585 are on a TTY, and thus unable to display on the fringes.
12586 That's because the text with the property will not be displayed anyway,
12587 so we need to signal to the caller that this is a "replacing"
12588 display spec. This fixes display when the spec is invalid or we
12591 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12593 * unexaix.c (make_hdr): Fix typo in prototype.
12594 This bug broke the build on AIX. Problem reported by Gilles Pion.
12596 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12598 * keyboard.c (kbd_buffer_get_event): Read special events also in
12599 batch mode. (Bug#11415)
12601 2012-05-12 Glenn Morris <rgm@gnu.org>
12603 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12605 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12607 * lisp.mk (lisp): Add newcomment.elc.
12609 2012-05-12 Glenn Morris <rgm@gnu.org>
12611 * Makefile.in (MKDIR_P): New, set by configure.
12612 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12614 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12616 Remove unused function hourglass_started.
12617 * dispextern.h (hourglass_started):
12618 * w32fns.c (hourglass_started):
12619 * xdisp.c (hourglass_started): Remove.
12621 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12623 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12624 Update dependencies.
12626 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12628 * xgselect.c (xg_select): Put maxfds+1 into a var.
12629 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12631 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12633 2012-05-10 Dave Abrahams <dave@boostpro.com>
12635 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12636 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12638 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12640 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12641 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12642 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12643 Initialize xd_registered_buses.
12645 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12647 Untag more efficiently if USE_LSB_TAG.
12648 This is based on a proposal by YAMAMOTO Mitsuharu in
12649 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12650 For an admittedly artificial (nth 8000 longlist) benchmark on
12651 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12652 Emacs's overall text size by 1%.
12653 * lisp.h (XUNTAG): New macro.
12654 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12655 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12656 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12657 * eval.c (Fautoload):
12658 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12659 * frame.h (XFRAME): Use XUNTAG.
12661 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12662 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12663 Remove unportable assumptions about print widths of types like
12665 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12666 intptr_t when converting between pointer and integer, to avoid GCC
12667 warnings about wrong width.
12669 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12671 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12672 stack for each reader_thread, instead of defaulting to 8MB
12673 determined by the linker. This avoids failures in creating
12674 subprocesses on Windows 7, see the discussion in this thread:
12675 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12677 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12679 Fix up display of the *Minibuf-0* buffer in the mini window.
12680 * keyboard.c (read_char): Don't clear the echo area if there's no
12682 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12683 contents of *Minibuf-0*) if there's no message displayed in its stead.
12685 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12687 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12690 2012-05-06 Chong Yidong <cyd@gnu.org>
12692 * lisp.mk (lisp): Update.
12694 2012-05-05 Jim Meyering <meyering@redhat.com>
12696 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12698 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12700 * data.c (PUT_ERROR): New macro.
12701 (syms_of_data): Use it. Add new error type `user-error'.
12702 * undo.c (user_error): New function.
12703 (Fprimitive_undo): Use it.
12704 * print.c (print_error_message): Adjust print style for `user-error'.
12705 * keyboard.c (user_error): New function.
12706 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12708 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12710 Do not limit current-time-string to years 1000..9999.
12711 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12712 (Fcurrent_time_string): Support any year that is supported by the
12713 underlying localtime representation. Don't use asctime, as it
12714 has undefined behavior for years outside the range -999..9999.
12716 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12718 Fix race conditions involving setenv, gmtime, localtime, asctime.
12719 Without this fix, interrupts could mess up code that uses these
12720 nonreentrant functions, since setting TZ invalidates existing
12721 tm_zone or tzname values, and since most of these functions return
12722 pointers to static storage.
12723 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12724 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12725 Grow the critical sections to include not just invoking
12726 localtime/gmtime, but also accessing these functions' results
12727 including their tm_zone values if any, and any related TZ setting.
12728 (format_time_string): Last arg is now struct tm *, not struct tm **,
12729 so that the struct tm is saved in the critical section.
12730 All callers changed. Simplify allocation of initial buffer, partly
12731 motivated by the fact that memory allocation needs to be outside
12732 the critical section.
12734 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12736 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12737 with RESET_INTERVAL.
12739 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12740 Remove duplicated buffer name initialization.
12742 2012-05-02 Jim Meyering <jim@meyering.net>
12744 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12746 * xfns.c (x_window): Use xstrdup (Bug#11375).
12748 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12750 * xdisp.c (pos_visible_p): If already at a newline from the
12751 display string before the 'while' loop, don't walk back the glyphs
12752 from it3.glyph_row. Solves assertion violation when the display
12753 string begins with a newline (egg.el). (Bug#11367)
12755 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12757 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12760 2012-05-01 Glenn Morris <rgm@gnu.org>
12762 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12763 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12764 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12765 All were removed before 23.1.
12767 * dispnew.c: Remove HAVE_LIBNCURSES test;
12768 it is always true on relevant platforms.
12770 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12771 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12773 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12775 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12777 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12778 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12781 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12783 Do not avoid creating empty evaporating overlays (Bug#9642).
12784 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12785 That is, do not delete an evaporating overlay if it becomes
12786 empty after its bounds are adjusted to fit within its buffer.
12787 This fix caused other problems, and I'm reverting it until we get
12788 to the bottom of them.
12790 2012-04-27 Chong Yidong <cyd@gnu.org>
12792 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12794 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12796 * xdisp.c (pos_visible_p): If the window start position is beyond
12797 ZV, start the display from buffer beginning. Prevents assertion
12798 violation in init_iterator when the minibuffer window is scrolled
12799 via the scroll bar.
12801 * window.c (window_scroll_pixel_based): Likewise.
12803 2012-04-27 Chong Yidong <cyd@gnu.org>
12805 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12807 2012-04-27 Glenn Morris <rgm@gnu.org>
12809 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12810 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12812 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12814 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12815 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12817 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12819 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12820 display element, check also the underlying string or buffer
12821 character. (Bug#11341)
12823 * w32menu.c: Include w32heap.h.
12824 (add_menu_item): If the call to AppendMenuW (via
12825 unicode_append_menu) fails, disable Unicode menus only if we are
12826 running on Windows 9X/Me.
12828 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12830 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

12851 Do not create empty overlays with the evaporate property (Bug#9642).
12852 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12853 if it becomes empty after its bounds are adjusted to fit within
12854 its buffer. Without this fix, in a nonempty buffer (let ((o
12855 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12856 yields an empty overlay that has the evaporate property, which is
12857 not supposed to happen.

12880 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12881 (__malloc_size_t, __malloc_ptrdiff_t):
12882 Remove. All uses removed, replaced by the definiens if needed,
12883 since we can assume C89 or better now.

12972 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12974 * sysdep.c [__FreeBSD__]: Minor cleanups.
12975 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12976 Use Emacs indenting style more consistently. Avoid some casts.
12977 Use 'double' consistently rather than mixing 'float' and 'double'.

12988 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12990 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12991 It is never used otherwise.
12993 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12995 * print.c (print_preprocess): Only check print_depth if print-circle

13002 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13003 set the status to "failed" and ensure that sentinel is run.
13005 2012-04-20 Glenn Morris <rgm@gnu.org>
13007 * process.c (Fset_process_inherit_coding_system_flag)
13008 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13058 New extern decls, to avoid calling undeclared functions.
13059 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13060 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13061 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13062 (NEED_MEM_INSERT): New macro.
13063 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13064 Remove one incorrect comment and fix another.

13100 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13101 * s/netbsd.h, s/sol2-6.h:
13102 Remove definition of GC_MARK_STACK, since the default now works.
13103 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13131 2012-04-11 Daniel Colascione <dancol@dancol.org>
13133 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13134 against is gone. It's better to use vfork now so that when Cygwin
13135 gains a new, working vfork, we use it automatically (bug#10398).
13137 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13187 (Fdefvar): Caller changed.
13189 * callint.c (Finteractive, Fcall_interactively):
13190 * minibuf.c (Fread_variable): Callers changed.
13192 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13194 * xdisp.c (set_cursor_from_row): If the display string appears in
13195 the buffer at position that is closer to point than the position
13196 after the display string, display the cursor on the first glyph of
13197 the display string. Fixes cursor display when a 'display' text
13198 property immediately follows invisible text. (Bug#11094)
13200 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13202 composite.c: use 'double' consistently
13203 * composite.c (get_composition_id): Use 'double' consistently
13204 instead of converting 'float' to 'double' and vice versa; this is
13205 easier to understand and avoids a GCC warning.
13207 2012-04-09 Glenn Morris <rgm@gnu.org>
13209 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13210 preparation for dumping it with emacs. (Bug#4789)

13254 [!WINDOWSNT]: New macros.
13255 (init_libxml2_functions, libxml2_loaded_p): New functions.
13256 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13257 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13258 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13259 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13261 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13262 Call init_libxml2_functions before calling libxml2 functions.
13263 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13265 * emacs.c: Don't include libxml/parser.h.
13266 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13267 xmlCleanupParser directly.
13269 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13271 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13273 * indent.c (Fvertical_motion): If there is a display string at
13274 point, use it.vpos to compute how many lines to backtrack after
13275 move_it_to point. (Bug#11133)
13277 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13279 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13280 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13281 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13282 macros related to unification of CJK characters. For the details,
13283 see the discussion following the message here:
13284 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13286 2012-04-04 Chong Yidong <cyd@gnu.org>
13288 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13290 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13292 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13293 instead of alloca. (Bug#11138)
13295 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13297 * w32menu.c (is_simple_dialog): Properly check lisp types.
13300 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13302 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13303 position we get to after a call to move_it_to fails the
13304 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13305 only if we wind up in a string from display property. (Bug#11063)
13307 * window.c (Fdelete_other_windows_internal): Invalidate the row
13308 and column information about mouse highlight, so that redisplay
13309 restores it after reallocating the glyph matrices. (Bug#7464)
13311 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13312 string comes from a `display' text property, use the buffer
13313 position of that property as if we actually saw that position in
13315 (move_it_by_lines): Remove the assertion that
13316 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13317 violated when there's a before-string at the beginning of a line.
13320 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13322 * xdisp.c (append_space_for_newline): If the default face was
13323 remapped, use the remapped face for the appended newline.
13324 (extend_face_to_end_of_line): Use the remapped default face for
13325 extending the face to the end of the line.
13326 (display_line): Call extend_face_to_end_of_line when the default
13327 face was remapped. (Bug#11068)
13329 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13331 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13333 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13335 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13337 2012-03-27 Glenn Morris <rgm@gnu.org>
13339 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13342 2012-03-26 Kenichi Handa <handa@m17n.org>
13344 * dispextern.h (struct glyph): Fix previous change. Change the
13345 bit length of glyphless.ch to 25 (Bug#11082).
13347 2012-03-26 Chong Yidong <cyd@gnu.org>
13349 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13350 (command_loop_1): Use it; inhibit selection update for
13351 handle-select-window too (Bug#8996).
13353 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13355 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13357 2012-03-25 Kenichi Handa <handa@m17n.org>
13359 * dispextern.h (struct glyph): Change the bit length of
13360 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13362 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13364 * s/ms-w32.h (tzname): Include time.h before redirecting to
13365 _tzname. Fixes the MSVC build. (Bug#9960)
13367 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13369 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13372 * xterm.c (XTread_socket): Only modify handling_signal if
13373 !SYNC_INPUT. (Bug#11080)
13375 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13377 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13378 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13379 when fetching a multibyte character consumes more bytes than
13380 CHAR_BYTES returns, due to unification of CJK characters in
13381 string_char. (Bug#11073)
13383 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13385 * process.c (wait_reading_process_output): Handle pty disconnect
13386 by refraining from sending oneself a SIGCHLD (bug#10933).
13388 2012-03-22 Chong Yidong <cyd@gnu.org>
13390 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13392 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13393 Mark string as coming from a prefix property.
13394 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13395 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13397 2012-03-21 Chong Yidong <cyd@gnu.org>
13399 * xfaces.c (Vface_remapping_alist): Doc fix.
13401 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13403 * w32proc.c (Fw32_set_console_codepage)
13404 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13407 2012-03-20 Chong Yidong <cyd@gnu.org>
13409 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13410 to reflect default non-nil value of redisplay-dont-pause.
13412 2012-03-19 Kenichi Handa <handa@m17n.org>
13414 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13415 it fit in a valid range (Bug#11003).
13417 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13419 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13420 that is not from display property, accept the row as a "cursor
13421 row" if one of the string's character has a non-nil `cursor'
13422 property. Fixes cursor positioning when there are newlines in
13423 overlay strings, e.g. in icomplete.el. (Bug#11035)
13425 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13427 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13429 2012-03-12 Chong Yidong <cyd@gnu.org>
13431 * eval.c (inhibit_lisp_code): Rename from
13432 inhibit_window_configuration_change_hook; move from window.c.
13434 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13435 * window.c (run_window_configuration_change_hook)
13436 (syms_of_window): Callers changed.

13442 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13444 2012-03-10 Chong Yidong <cyd@gnu.org>
13446 * frame.c (other_visible_frames): Don't assume the selected frame
13447 is visible (Bug#10955).
13449 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13451 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

13455 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13456 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13459 2012-03-03 Glenn Morris <rgm@gnu.org>
13461 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13463 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13465 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13466 position past the first glyph_row that ends at ZV. (Bug#10902)
13467 (redisplay_window, next_element_from_string): Fix typos in
13469 (redisplay_window): Pass to move_it_vertically the margin in
13470 pixels, not in screen lines.
13472 2012-03-02 Glenn Morris <rgm@gnu.org>
13474 * buffer.c (buffer-list-update-hook): Doc fix.
13476 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13478 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13479 push_it before setting up the iterator for the first overlay
13480 string, even if we have an empty string loaded.
13481 (next_overlay_string): If there's an empty string on the iterator
13482 stack, pop the stack. (Bug#10903)
13484 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13486 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13487 Suggested by Stefan Monnier in
13488 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13489 * alloc.c (widen_to_Lisp_Object): New static function.
13490 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13491 and widening them to Lisp_Objects. This would work even if
13492 USE_LSB_TAG is defined and wide integers are used, which might
13493 happen in a future version of Emacs.
13495 2012-02-25 Chong Yidong <cyd@gnu.org>
13497 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13500 * xselect.c (Fx_selection_exists_p): Doc fix.
13501 (x_clipboard_manager_save_all): Print an informative message
13502 before saving to clipboard manager.
13504 2012-02-24 Chong Yidong <cyd@gnu.org>
13506 * keyboard.c (process_special_events): Handle all X selection
13507 requests in kbd_buffer, not just the next one (Bug#8869).
13509 2012-02-23 Chong Yidong <cyd@gnu.org>
13511 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13512 call when setting menu-bar-lines and tool-bar-lines parameters.
13513 (unwind_create_frame_1): New helper function.
13515 * window.c (inhibit_window_configuration_change_hook): New var.
13516 (run_window_configuration_change_hook): Obey it.
13517 (syms_of_window): Initialize it.
13519 2012-02-22 Chong Yidong <cyd@gnu.org>
13521 * xterm.c (x_draw_image_relief): Add missing type check for
13522 Vtool_bar_button_margin (Bug#10743).
13524 2012-02-21 Chong Yidong <cyd@gnu.org>
13526 * fileio.c (Vfile_name_handler_alist): Doc fix.
13528 * buffer.c (Fget_file_buffer): Protect against invalid file
13529 handler return value.
13531 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13533 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13534 when computing $valmask.
13536 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13537 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13538 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13539 It's useless in that case, and it can cause problems on hosts
13540 that allocate halves of EMACS_INT values separately.
13541 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13542 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13543 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13544 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13545 it avoids undefined behavior on hosts where shifting right by more
13546 than the word width has undefined behavior.
13548 2012-02-19 Chong Yidong <cyd@gnu.org>
13550 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13551 (Funhandled_file_name_directory, Ffile_name_as_directory)
13552 (Fdirectory_file_name, Fexpand_file_name)
13553 (Fsubstitute_in_file_name): Protect against invalid file handler
13554 return values (Bug#10845).
13556 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13558 * .gdbinit (pitx): Fix incorrect references to fields of the
13561 2012-02-17 Chong Yidong <cyd@gnu.org>

13565 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13567 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13568 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13570 2012-02-15 Chong Yidong <cyd@gnu.org>
13572 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13573 marked as special. Also, starting docstrings with * is obsolete.
13575 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13577 * gnutls.c (emacs_gnutls_write): Fix last change.

13581 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
13584 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
13586 * keymap.c (Fsingle_key_description): Handle char ranges.
13588 2012-02-12 Chong Yidong <cyd@gnu.org>
13590 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13591 as that creates a dangerous corner case.
13593 * window.c (Fdelete_window_internal): Invalidate the mouse
13594 highlight (Bug#9904).
13596 2012-02-12 Glenn Morris <rgm@gnu.org>
13598 * xselect.c (Fx_own_selection_internal)
13599 (Fx_get_selection_internal, Fx_disown_selection_internal)
13600 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13601 * nsselect.m (Fx_own_selection_internal)
13602 (Fx_disown_selection_internal, Fx_selection_exists_p)
13603 (Fx_selection_owner_p, Fx_get_selection_internal):
13604 Sync docs and argument specs with the xselect.c versions.
13606 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13608 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13610 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13612 * w32select.c (Fx_selection_exists_p): Sync doc string and
13613 argument list with xselect.c. (Bug#10783)
13615 * w16select.c (Fx_selection_exists_p): Sync doc string and
13616 argument list with xselect.c. (Bug#10783)

13622 2012-02-09 Kenichi Handa <handa@m17n.org>
13624 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13626 2012-02-07 Chong Yidong <cyd@gnu.org>
13628 * buffer.c (Fbuffer_local_variables)
13629 (buffer_lisp_local_variables): Handle unbound vars correctly;
13630 don't let Qunbound leak into Lisp.
13632 2012-02-07 Glenn Morris <rgm@gnu.org>
13634 * image.c (Fimagemagick_types): Doc fix.
13636 * image.c (imagemagick-render-type): Change it from a lisp object
13637 to an integer. Move the doc here from the lisp manual.
13638 Treat all values not equal to 0 the same.
13640 2012-02-06 Chong Yidong <cyd@gnu.org>
13642 * doc.c (store_function_docstring): Avoid applying docstring of
13643 alias to base function (Bug#2603).

13654 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13656 * w32.c (get_emacs_configuration_options):
13657 Include --enable-checking, if specified, in the return value.
13659 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13661 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13662 after rounding frame sizes. (Bug#9723)
13664 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13666 * keyboard.c (adjust_point_for_property): Don't position point
13667 before BEGV. (Bug#10696)
13669 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13671 Handle overflow when computing char display width (Bug#9496).
13672 * character.c (char_width): Return EMACS_INT, not int.
13673 (char_width, c_string_width): Check for overflow when
13674 computing the width; this is possible now that individual
13675 characters can have unbounded width. Problem introduced
13676 by merge from Emacs 23 on 2012-01-19.
13678 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13680 * dbusbind.c (Fdbus_register_method): Mention the return value
13681 :ignore in the docstring.
13683 2012-02-02 Glenn Morris <rgm@gnu.org>
13685 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
13687 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13693 2012-02-02 Kenichi Handa <handa@m17n.org>
13695 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13696 0, do not call append_composite_glyph.
13698 2012-02-02 Kenichi Handa <handa@m17n.org>
13700 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13702 (x_produce_glyphs): If the component of a composition is a null
13703 string, set it->pixel_width to 1 to avoid zero-width glyph.
13705 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13707 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13708 first 2 arguments are identical. This makes inserting large
13709 output from a subprocess an order of magnitude faster on
13710 MS-Windows, where all sbrk'ed memory is always contiguous.
13712 2012-01-31 Glenn Morris <rgm@gnu.org>

14240 * xdisp.c (redisplay_window): If cursor row is not fully visible
14241 after recentering, and scroll-conservatively is set to a large
14242 number, scroll window by a few more lines to make the cursor fully
14243 visible and out of scroll-margin. (Bug#10105)
14244 (start_display): Don't move to the next line if the display should
14245 start at a newline that is part of a display vector or an overlay
14246 string. (Bug#10119)

14326 Otherwise, valgrind does not work on some platforms.
14327 Problem reported by Andreas Schwab in
14328 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14329 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14330 is set, removing the need for VIRT_ADDRESS_VARIES.
14331 (PURE_P): Use a more-efficient implementation that needs just one
14332 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14333 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14334 to 4 (xorl, subq, cmpq, setbe).
14335 * alloc.c (pure): Always extern now, since that's the
14336 VIRT_ADDR_VARIES behavior.

14338 consistency with the new puresize.h.
14339 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14340 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14346 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14347 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14348 behave as if the cursor position were at the window margin.
14350 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14351 and the cursor position is out of bounds, behave as if the cursor
14352 position were at the window margin. (Bug#10075)
14354 2011-11-18 Chong Yidong <cyd@gnu.org>
14356 * window.c (Fwindow_combination_limit): Make first argument

14375 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14377 * xdisp.c (row_hash): New function, body extracted from
14378 compute_line_metrics.
14379 (compute_line_metrics): Call row_hash, instead of computing the
14382 * dispnew.c (verify_row_hash): Call row_hash for computing the
14383 hash code of a row, instead of duplicating code from xdisp.c.
14385 * dispextern.h (row_hash): Add prototype.
14387 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14389 * frame.c (delete_frame): Don't delete the terminal when the last

14423 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14425 * xdisp.c (display_line): Move the call to
14426 highlight_trailing_whitespace before the call to
14427 compute_line_metrics, since the latter needs to see the final
14428 faces of all the glyphs to compute ROW's hash value.
14429 Fixes assertion violations in row_equal_p. (Bug#10035)
14431 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14433 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14434 just return (bug#10044).
14436 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14438 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14439 with user-defined heap size. Bump the default size of the temacs
14440 heap to 27MB, to avoid memory warning when running temacs.

14443 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14444 current_matrix and desired_matrix. (Bug#9990)
14445 (verify_row_hash) [XASSERTS]: New function.
14446 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

14490 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14492 Avoid some portability problems by eschewing 'extern inline' functions.
14493 The trivial performance wins aren't worth the portability hassles; see
14494 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14496 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14562 * xmenu.c (cleanup_widget_value_tree): New function.
14563 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14564 calling free_menubar_widget_value_tree directly (Bug#9830).

14570 (window_box_width, window_box_left, window_box_left_offset)
14571 (window_box_right, window_box_right_offset): Declare extern.
14572 Otherwise, these inline functions do not conform to C99 and
14573 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14574 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14575 * intervals.c (adjust_intervals_for_insertion)

14578 (static_offset_intervals): Remove.
14579 (offset_intervals): Rewrite using the old contents of
14580 static_offset_intervals. The old version didn't conform to C99
14581 because an extern inline function contained a reference to an
14582 identifier with static linkage.

14634 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
14635 (unwind_create_frame): New function (Bug#9943).
14636 (Fx_create_frame): Restructure code to be more similar to the one in
14637 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

14676 [_MSC_VER]: Include sys/timeb.h, sys/stat.h, and signal.h.
14677 (fstat, stat, utime) [_MSC_VER]: Redirect to their sys_* cousins.
14678 (malloc, free, realloc, calloc) [_MSC_VER]: Always redirect to the
14680 (alloca) [_MSC_VER]: Define to _alloca.
14682 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
14684 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
14686 2011-11-04 Eli Zaretskii <eliz@gnu.org>
14688 * xdisp.c (note_mouse_highlight): If either of
14689 previous/next-single-property-change returns nil, treat that as
14690 the beginning or the end of the buffer. (Bug#9955)
14692 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14694 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
14695 label is not null (Bug#9951).
14696 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
14699 2011-11-04 Eli Zaretskii <eliz@gnu.org>
14701 * window.c (Fwindow_body_size): Mention in the doc string that the
14702 return value is in frame's canonical units. (Bug#9949)
14704 2011-11-03 Eli Zaretskii <eliz@gnu.org>
14706 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
14708 * w32fns.c (unwind_create_frame): If needed, free the glyph

14714 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
14715 Don't stop backward scan on the continuation glyph, even though
14716 its CHARPOS is positive.
14717 (mouse_face_from_buffer_pos, note_mouse_highlight):
14718 Rename cover_string to disp_string.
14720 2011-11-01 Martin Rudalics <rudalics@gmx.at>
14722 * window.c (temp_output_buffer_show): Don't use
14723 Vtemp_buffer_show_specifiers.
14724 (Vtemp_buffer_show_specifiers): Remove unused variable.
14726 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14728 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14729 past the beginning of the current glyph matrix.
14731 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14733 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14734 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14735 HAVE_GTK3 (Bug#9869).
14737 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
14738 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14740 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14742 * xterm.c: Declare x_handle_net_wm_state to return int.
14743 (handle_one_xevent): Check if we are iconified but don't have
14744 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14745 (get_current_wm_state): Return non-zero if not hidden,
14746 check for _NET_WM_STATE_HIDDEN (Bug#9893).

14751 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14753 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14754 so that this new function doesn't get optimized away by a
14755 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14757 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14759 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14761 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14763 Fix the `xbytecode' command.
14764 * .gdbinit (xprintbytestr): New command.
14765 (xwhichsymbols): Rename from `which'; all callers changed.
14766 (xbytecode): Print the byte-code string as well.
14768 2011-10-29 Kim Storm <storm@cua.dk>
14770 * alloc.c (which_symbols): New function.
14772 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14774 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14777 2011-10-29 Glenn Morris <rgm@gnu.org>
14779 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14780 Not clear what it was for, and it causes various bugs. (Bug#9839)
14782 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14784 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14785 possible random value that matches one of those tested as
14786 condition to clear the mouse face.
14788 2011-10-28 Chong Yidong <cyd@gnu.org>
14790 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14792 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14794 * window.c (make_window): Initialize phys_cursor_on_p.
14796 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14798 * lisp.h (struct Lisp_Symbol): Update comments.
14800 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14802 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14804 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14806 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14807 <oslsachem@gmail.com> for helping to debug this.
14809 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14810 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14811 (g_b_init_get_glyph_outline_w): New static variables.
14812 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14813 (GetGlyphOutlineW_Proc): New typedefs.

14815 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14817 (w32font_open_internal, compute_metrics):
14818 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14819 instead of calling the "wide" APIs directly.
14821 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14823 * w32.h (syms_of_w32font): Add prototype.
14825 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14827 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14828 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14829 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14830 (Fmove_to_window_line): Doc fix.
14832 2011-10-27 Chong Yidong <cyd@gnu.org>
14834 * process.c (make_process): Set gnutls_state to NULL.
14836 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14837 non-NULL, regardless of GNUTLS_INITSTAGE.
14838 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14839 an error. Set process slots as soon as we allocate them.
14841 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14843 2011-10-27 Chong Yidong <cyd@gnu.org>
14845 * gnutls.c (emacs_gnutls_deinit): New function.
14846 Deallocate credentials structures as well as calling gnutls_deinit.
14847 (Fgnutls_deinit, Fgnutls_boot): Use it.
14849 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14850 (deactivate_process): Call emacs_gnutls_deinit.
14852 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14854 * image.c (x_create_x_image_and_pixmap):
14855 * w32.c (sys_rename, w32_delayed_load):
14856 * w32font.c (fill_in_logfont):

14859 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14861 * w32fns.c (w32_default_color_map): New function,
14862 extracted from Fw32_default_color_map.
14863 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14865 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14867 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14869 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14871 * keyboard.c (test_undefined): New function (bug#9751).
14872 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14874 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14876 * sysdep.c (init_sys_modes): Fix the check for the controlling
14877 terminal (Bug#6649).
14879 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14881 * dispextern.h (struct bidi_it): New member next_en_type.
14883 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14884 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14885 current character, check also for next_en_type being WEAK_EN.
14886 (bidi_resolve_weak): Don't enter the expensive loop if the current
14887 position is before next_en_pos. Record the bidi type of the first
14888 non-ET, non-BN character we find, in addition to its position.
14889 (bidi_level_of_next_char): Invalidate next_en_type when
14890 next_en_pos is over-stepped.
14892 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14894 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14895 * editfns.c: Rewrite current-time-zone so that it invokes
14896 the equivalent of (format-time-string "%Z") to get the time zone name.
14897 This fixes a bug when the time zone name contains characters that
14898 need converting from the system time locale to Emacs internal format.
14899 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14900 that patch fixed format-time-string to do the conversion, but
14901 I forgot to fix current-time-zone.
14902 (format_time_string): New function, containing most of
14903 what Fformat_time_string used to contain.
14904 (Fformat_time_string): Rewrite in terms of format_time_string.
14905 This doesn't change this function's behavior.
14906 (current-time-zone): Rewrite to use format_time_string.
14907 This fixes the bug reported by Michael Schierl in
14908 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14909 Jason Rumney's 2007-06-07 change worked around this bug, but
14911 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14913 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14915 * xdisp.c (start_display): If the character at POS is displayed
14916 via a display vector, reset IT->current.dpvec_index to zero.
14917 (try_window_reusing_current_matrix): If a line ends in a display
14918 vector or the next line starts in a display vector, continue
14919 redrawing the window even though the character position of
14920 start_row was reached.
14923 2011-10-18 Chong Yidong <cyd@gnu.org>
14925 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14926 with nobreak-char-display too.
14928 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14930 Fix part 3 of bug#9771.
14931 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14932 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14933 non-neutral characters if the current character is a paragraph
14934 separator (a.k.a. Newline). This avoids running the same
14935 expensive loop twice, once when we consume the preceding newline
14936 and the other time when the line actually needs to be displayed.
14937 Avoid the loop when we see neutrals on the base embedding level
14938 following a character whose directionality is the same as the
14939 paragraph's. This avoids running the expensive loop when a line
14940 ends in a long sequence of neutrals, like control characters.
14941 Add assertion against STRONG_AL type. Slightly rearrange code
14942 that determines the type of a neutral given the first non-neutral
14944 (bidi_level_of_next_char): Set next_en_pos to zero when
14945 invalidating its info.
14947 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14949 * xdisp.c (push_display_prop): Determine whether to record string
14950 or buffer position by IT->string, not by IT->method. Allow
14951 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14952 (move_it_vertically_backward): Don't look for character position
14953 immediately after the newline when in a continuation line.
14956 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14958 * window.c (coordinates_in_window): Rewrite and delabelize
14959 vertical border check. (Bug#5357) (Bug#9618)
14961 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14963 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14964 errors in XSetWindowBorder (bug#9310).
14966 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14968 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14969 avoid crash when xmalloc overrun checking is enabled.
14971 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14973 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14974 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14975 cursor motion with <left> and <right> arrow keys.
14977 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14978 some callers set that themselves.
14980 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14982 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14983 display string and the previous row comes from the same string and
14984 is empty. (Bug#9739) (Bug#9738)
14986 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14988 * doc.c (get_doc_string): Encode file name (bug#9735).
14990 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14992 * bidi.c (bidi_level_of_next_char):
14993 * xdisp.c (get_visually_first_element): Remove old incorrect
14994 comments regarding the Unicode Line Separator character.
14996 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14998 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15000 * alloc.c (Fgc_status): Do not access beyond zombies array
15001 boundary if nzombies > MAX_ZOMBIES.
15002 * alloc.c (dump_zombies): Add missing format specifier.
15004 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15006 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15007 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15009 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15010 Some packages use them to denote characters with modifiers.
15012 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15014 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15015 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15016 matching a pp-number. Rename parameter var to var1.
15018 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15020 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15022 2011-10-08 Glenn Morris <rgm@gnu.org>
15024 * callint.c (Fcall_interactively): Give a more explicit error for the
15025 'c' case with a non-character input. (Bug#8479)
15027 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15029 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15031 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15032 lines that are hscrolled on the left.
15034 * dispnew.c (buffer_posn_from_coords): Account for a possible
15035 presence of header-line. (Bug#4426)
15037 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15039 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15040 Don't advertise functionality which we discourage or doesn't work.
15042 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15044 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15045 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15046 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15047 this makes Emacs dump core during garbage collection on rare
15048 occasions. sizeof is obviously inferior to offsetof here, so
15049 stick with offsetof.
15050 (GC_POINTER_ALIGNMENT): New macro.
15051 (mark_memory): Omit 3rd (offset) arg; caller changed.
15052 Don't assume EMACS_INT alignment is the same as pointer alignment.
15054 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15056 * keyboard.c (read_key_sequence_remapped): New var.
15057 (read_key_sequence): Compute remapping in the right buffer.
15058 (command_loop_1): Use read_key_sequence's remapping directly.
15060 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15062 * dired.c (file_name_completion): Don't expand file name.
15063 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15064 before checking file name handler.
15066 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15067 they've been requested explicitly (bug#9591).
15069 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15071 * keymap.c (Fsingle_key_description): Use make_specified_string
15072 instead of build_string to build string from push_key_description.
15075 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15077 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15078 This fixes a Y2038 bug on 64-bit hosts.
15079 * buffer.c (reset_buffer):
15080 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15081 (Fclear_buffer_auto_save_failure):
15082 Use 0, not -1, to represent an unset failure time, since time_t
15083 might not be signed.
15085 Remove dependency on glibc malloc internals.
15086 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15087 Move back here from lisp.h, but with their new implementations.
15088 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15089 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15090 * charset.c (charset_table_init): New static var.
15091 (syms_of_charset): Use it instead of xmalloc. This removes a
15092 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15093 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15094 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15095 Move back to alloc.c.
15096 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15097 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15099 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15101 * nsterm.m (windowDidResize): Call x_set_window_size only when
15102 ns_in_resize is true. Otherwise set pixelwidth/height and
15103 call change_frame_size (Bug#9628).
15105 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15107 Port --enable-checking=all to Fedora 14 x86-64.
15108 * charset.c (syms_of_charset): Also account for glibc malloc's
15109 internal overhead when calculating the initial malloc maximum.
15111 Port --enable-checking=all to Fedora 14 x86.
15112 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15114 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15115 (overrun_check_realloc, overrun_check_free):
15116 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15117 That way, xmalloc returns a properly-aligned pointer even if
15118 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15119 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15120 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15121 into account when calculating the initial malloc maximum.
15122 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15123 Move here from alloc.c, so that charset.c can use it too.
15124 Properly align; the old code wasn't right for common 32-bit hosts
15125 when configured with --enable-checking=all.
15126 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15127 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15129 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15131 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15134 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15136 * xdisp.c (compute_display_string_end): If there's no display
15137 string at CHARPOS, return -1.
15139 * bidi.c (bidi_fetch_char): When compute_display_string_end
15140 returns a negative value, treat the character as a normal
15141 character not covered by a display string. (Bug#9624)
15143 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15145 * lread.c (Fread_from_string): Fix typo in docstring.
15147 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15149 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15150 newline, reseat the iterator instead of bidi-iterating there one
15151 character at a time. (Bug#9610)
15152 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15153 TO_CHARPOS if the bidi iterator is at base embedding level.
15155 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15157 * lread.c (readevalloop): Use correct code for NBSP.
15158 (read1): Likewise. (Bug#9608)
15160 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15162 * dbusbind.c (Fdbus_register_signal): When service is not
15163 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15165 2011-09-25 Glenn Morris <rgm@gnu.org>
15167 * buffer.c (truncate-lines): Doc fix.
15169 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15171 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15172 (Fset_window_next_buffers): Doc fix.
15174 2011-09-24 Glenn Morris <rgm@gnu.org>
15176 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15178 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15180 Fix minor problems found by static checking.

15182 * indent.c (Fvertical_motion): Fix == vs = typo.
15184 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15186 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15187 Default value is now t. Doc fix.
15189 * indent.c (Fvertical_motion): Compute and apply the overshoot
15190 logic when moving up, not only when moving down. Fix the
15191 confusing name and values of the it_overshoot_expected variable;
15192 logic changes accordingly. (Bug#9254) (Bug#9549)
15194 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15195 CHARPOS is covered by a display string which includes newlines.
15196 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15197 is covered by a display string with embedded newlines.
15199 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15201 * dbusbind.c (Fdbus_register_signal): Add match rule to
15202 Vdbus_registered_objects_table. (Bug#9581)
15203 (Fdbus_register_method, Vdbus_registered_objects_table):
15206 2011-09-24 Jim Meyering <meyering@redhat.com>
15208 do not ignore write error for any output size
15209 The previous change was incomplete.
15210 While it makes emacs --batch detect the vast majority of stdout
15211 write failures, errors were still ignored whenever the output size is
15212 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15213 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15214 && echo FAIL: ignored write error
15215 FAIL: ignored write error
15216 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15217 && echo FAIL: ignored write error
15218 FAIL: ignored write error
15219 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15221 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15223 * emacs.c (Fkill_emacs): In noninteractive mode exit
15224 non-successfully if a write error occurred on stdout. (Bug#9574)
15226 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15228 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15231 * dispextern.h (struct it): Update the comment documenting what
15234 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15236 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15237 a display string, extend search for cursor position to end of row.
15238 (find_row_edges): If the row ends in a newline from a display
15239 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15240 Handle the case of a display string with multiple newlines.
15241 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15242 non-empty line. Fixes confusing cursor motion with arrow keys at
15243 the beginning of a line that starts with whitespace.
15245 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15247 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15250 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15252 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15253 boolean (Bug#9154).
15255 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15257 * xdisp.c (display_line): Record maximum and minimum buffer
15258 positions even if no glyphs were produced (e.g., by a zero-width
15259 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15260 buffer positions that will be removed from the glyph row because
15262 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15263 column is beyond frame width: don't subtract 1 "pixel" when
15264 computing width of the stretch.
15265 (reseat_at_next_visible_line_start): Undo the change made on
15266 2011-09-17 that saved paragraph information and restored it after
15267 the call to `reseat'. (Bug#9545)
15269 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15271 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15272 and turn window cursor on if cleared (Bug#9415).
15274 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15276 * search.c (boyer_moore): Take unibyte characters from pattern
15277 literally. (Bug#9458)
15279 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15281 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15283 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15285 Fix minor problem found by static checking.
15286 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15287 initialized, to pacify gcc -Wuninitialized.
15289 * fileio.c: Report proper errno when syscall falls.
15290 (Finsert_file_contents): Save and restore errno,
15291 so that report_file_error outputs the correct diagnostic.
15292 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15294 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15296 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15298 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15300 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15301 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15303 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15305 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15306 about the current paragraph and restore it after the call to reseat.
15308 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15309 (bidi_find_paragraph_start): Search back for paragraph beginning
15310 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15311 (bidi_move_to_visually_next): Only trigger paragraph-related
15312 computations when the last character is a newline or at EOB, not
15313 just any NEUTRAL_B. (Bug#9470)
15315 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15316 truncated lines if point is covered by a display string. (Bug#9524)
15318 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15320 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15321 (cons_to_x_long): New function.
15322 (lisp_data_to_selection_data): Use it. Correct the test for
15323 short-versus-long data; it was negated. Break out of vector
15324 loop, for efficiency, when a long datum is discovered.
15326 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15328 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15330 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15332 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15333 GCC PR/17406) by declaring this function with external scope.
15335 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15337 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15338 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15340 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15342 * editfns.c (Fformat): Correctly handle text properties on "%%".

15351 (fill_composite_glyph_string): Add comments about special meaning
15352 of TAB characters in a composition.
15354 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15356 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15357 This occurs when processing a multibyte format.
15358 Problem reported by Wolfgang Jenker.
15360 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15362 * xdisp.c (try_cursor_movement): Only check for exact match if
15363 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15365 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15367 Remove unused external symbols.
15368 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15369 * xdisp.c (calc_pixel_width_or_height): Now static.
15370 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15371 * indent.c (check_display_width):
15372 * w32term.c: Fix comment to match code.
15373 * xterm.c, xterm.h (x_catching_errors): Remove.
15375 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15377 * xselect.c: Use signed conversions more consistently (Bug#9498).
15378 (selection_data_to_lisp_data): Assume incoming selection data are
15379 signed integers, not unsigned. This is to be consistent with
15380 outgoing selection data, which was modified to use signed integers
15381 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15382 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15383 expects long, not unsigned long.
15385 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15387 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15388 computation of loop end. Reported by Johan Bockgård
15391 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15393 * frame.c (Fother_visible_frames_p): Function deleted.
15395 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15397 * indent.c (compute_motion): Process display vector front to back
15398 rather than the other way around. (Bug#2496)
15400 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15402 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15404 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15406 * minibuf.c (Fread_from_minibuffer): Doc fix.
15408 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15410 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15411 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15413 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15415 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15416 value for non-existent files.
15418 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15420 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15421 set its "size" to -1. This will set the modtime_size field of
15422 the corresponding buffer to -1, which is what
15423 verify-visited-file-modtime expects for files that do not exist.
15426 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15428 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15430 * lisp.h: ... from here. push_key_description is no longer
15431 defined in keyboard.c, so its declaration should not be in
15432 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15433 logically belongs with push_key_description.
15435 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15437 * buffer.h: Include <sys/types.h> instead of <time.h>.
15438 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15439 Problem reported by Herbert J. Skuhra.
15441 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15443 * xml.c (parse_region): Make the parsing work for
15444 non-comment-starting XML files again (bug#9144).
15446 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15448 * image.c (gif_load): Fix calculation of bottom and right corner.
15451 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15453 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15454 redisplay in small windows.
15456 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15458 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15460 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15462 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15463 Operate on live windows only.
15465 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15467 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15469 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15471 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15472 only under bidi iteration.
15474 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15476 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15478 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15480 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15481 Without this fix, the command to link temacs failed due to an
15482 undefined symbol __builtin_isnan. This is because
15483 /usr/include/iso/math_c99.h #defines isnan(x) to
15484 __builtin_isnan(x), but the bundled gcc, which identifies itself
15485 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15487 * floatfns.c (isnan): #undef, and then #define to a clone of
15489 (Fisnan): Always define, since it's always available now.
15490 (syms_of_floatfns): Always define isnan at the Lisp level.
15492 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15494 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15496 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15498 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15499 The previous code assumed that file offsets (off_t values) fit in
15500 EMACS_INT variables, which is not true on typical 32-bit hosts.
15501 The code messed up by falsely reporting buffer overflow in cases
15502 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15503 when "big" contains more than 2**29 bytes, even though this
15504 inserts just one byte and does not overflow the buffer.
15505 (Finsert_file_contents): Store file offsets as off_t
15506 values, not as EMACS_INT values. Check for overflow when
15507 converting between EMACS_INT and off_t. When checking for
15508 buffer overflow or for overlap, take the offsets into account.
15509 Don't use EMACS_INT for small values where int suffices.
15510 When checking for overlap, fix a typo: ZV was used where
15511 ZV_BYTE was intended.
15512 (Fwrite_region): Don't assume off_t fits into 'long'.
15513 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15515 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15517 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15519 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15521 sprintf-related integer and memory overflow issues (Bug#9412).
15523 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15524 (esprintf, exprintf, evxprintf): New functions.
15525 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15526 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15527 (modify_event_symbol): Do not assume that the length of
15528 name_alist_or_stem is safe to alloca and fits in int.
15529 (Fexecute_extended_command): Likewise for function name and binding.
15530 (Frecursion_depth): Wrap around reliably on integer overflow.
15531 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15532 since some callers pass EMACS_INT values.
15533 (Fsingle_key_description): Don't crash if symbol name contains more
15534 than MAX_ALLOCA bytes.
15535 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15536 (get_minibuffer): Arg is now EMACS_INT, not int.
15537 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15538 (esprintf, exprintf, evxprintf): New decls.
15539 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15541 * dbusbind.c (signature_cat): New function.
15542 (xd_signature, Fdbus_register_signal):
15543 Do not overrun buffer; instead, report string overflow.
15545 * dispnew.c (add_window_display_history): Don't overrun buffer.
15546 Truncate instead; this is OK since it's just a log.
15548 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15549 even if the time zone offset is outlandishly large.
15550 Don't mishandle offset == INT_MIN.
15552 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15553 when creating daemon; the previous buffer-overflow check was incorrect.
15555 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15556 which has the guts of the old verror function.
15558 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15559 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15561 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15562 (font_unparse_xlfd): Don't blindly alloca long strings.
15563 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15564 fits in int, when using sprintf. Use single snprintf to count
15565 length of string rather than counting it via multiple sprintfs;
15566 that's simpler and more reliable.
15567 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15568 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15569 sprintf, in case result does not fit in int.
15571 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15572 (fontset_from_font): Print it.
15574 * frame.c (tty_frame_count): Now printmax_t, not int.
15575 (make_terminal_frame, set_term_frame_name): Print it.
15576 (x_report_frame_params): In X, window IDs are unsigned long,
15577 not signed long, so print them as unsigned.
15578 (validate_x_resource_name): Check for implausibly long names,
15579 and don't assume name length fits in 'int'.
15580 (x_get_resource_string): Don't blindly alloca invocation name;
15581 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15584 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15585 (xg_check_special_colors, xg_set_geometry):
15586 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15588 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15589 Use esprintf, not sprintf, in case result does not fit in int.
15591 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15592 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15593 it as a large positive number.

15595 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15597 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15598 in case result does not fit in int.
15600 * print.c (float_to_string): Detect width overflow more reliably.
15601 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15602 buffer overrun. Don't assume list length fits in 'int'. Treat
15603 print length of 0 as 0, not as infinity; to be consistent with other
15604 uses of print length in this function. Don't overflow print length
15605 index. Don't assume hash table size fits in 'long', or that
15606 vectorlike size fits in 'unsigned long'.
15608 * process.c (make_process): Use printmax_t, not int, to format
15609 process-name gensyms.
15611 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15613 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15614 to avoid potential buffer overrun.
15616 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15617 if X resource line is longer than 512 bytes.
15619 * xfns.c (x_window): Make sprintf buffer a bit bigger
15620 to avoid potential buffer overrun.
15622 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15624 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15626 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15628 Integer overflow fixes for scrolling, etc.
15629 Without these, Emacs silently mishandles large integers sometimes.
15630 For example, "C-u 4294967297 M-x recenter" was treated as if
15631 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15633 * xdisp.c (try_window_id): Check Emacs fixnum range before
15634 converting to 'int'.
15636 * window.c (window_scroll_line_based, Frecenter):
15637 Check that an Emacs fixnum is in range before assigning it to 'int'.
15638 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15639 values converted from Emacs fixnums.
15640 (Frecenter): Don't wrap around a line count if it is out of 'int'
15641 range; instead, treat it as an extreme value.
15642 (Fset_window_configuration, compare_window_configurations):
15643 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15645 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15646 that can exceed INT_MAX. Check that EMACS_INT value is in range
15647 before assigning it to the (possibly-narrower) index.
15648 (match_limit): Don't assume that a fixnum can fit in 'int'.
15650 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15653 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15654 (Fvertical_motion): Don't wrap around LINES values that don't fit
15655 in 'int'. Instead, treat them as extreme values. This is good
15656 enough for windows, which can't have more than INT_MAX lines anyway.
15658 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15660 * Require libxml/parser.h to avoid compilation warning.
15662 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15664 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15665 since this reportedly can destroy thread storage.
15667 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15669 * syntax.c (find_defun_start): Update all cache variables if
15670 exiting early (Bug#9401).
15672 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15674 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15676 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15677 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15678 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15680 * term.c (tty_append_glyph): New function.
15681 (produce_stretch_glyph): Static function and its prototype deleted.
15683 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15686 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15688 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15689 when checking :margin (Bug#9390).
15690 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15691 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15692 so that the name doesn't mislead. All uses changed.
15694 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15696 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15699 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15701 * xdisp.c (move_it_to): Don't bail out early when reaching
15702 position beyond to_charpos, if we are scanning backwards.
15703 (move_it_vertically_backward): When DY == 0, make sure we get to
15704 the first character in the line after the newline.
15706 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15708 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15709 (ccl_driver): Do not generate an out-of-range pointer.
15710 (Fccl_execute_on_string): Remove unnecessary check for
15711 integer overflow, noted by Stefan Monnier in
15712 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15713 Remove a FIXME that didn't need fixing.
15714 Simplify the newly-introduced buffer reallocation code.
15716 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15718 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15720 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15722 Integer and memory overflow issues (Bug#9196).
15724 * doc.c (get_doc_string): Rework so that
15725 get_doc_string_buffer_size is the actual buffer size, rather than
15726 being 1 less than the actual buffer size; this makes xpalloc more
15729 * image.c (x_allocate_bitmap_record, cache_image):
15730 * xselect.c (Fx_register_dnd_atom):
15731 Simplify previous changes by using xpalloc.
15733 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15734 since either will do and ptrdiff_t is convenient with xpalloc.
15736 * charset.c (charset_table_size)
15737 (struct charset_sort_data.priority): Now ptrdiff_t.
15738 (charset_compare): Don't overflow if priorities differ greatly.
15739 (Fsort_charsets): Don't assume list length fits in int.
15740 Check for size-calculation overflow when allocating sort data.
15741 (syms_of_charset): Allocate an initial charset table that is
15742 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15744 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15746 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15747 The actual value is always <= INT_MAX, and leaving it unsigned made
15748 overflow checking harder.
15750 * dispextern.h (struct glyph_matrix.rows_allocated)
15751 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15752 with xpalloc. The values are still always <= INT_MAX.
15754 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15756 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15757 (SAFE_NALLOCA): New macro.
15759 * region-cache.c (struct boundary.pos, find_cache_boundary)
15760 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15761 (set_cache_region, invalidate_region_cache)
15762 (revalidate_region_cache, know_region_cache, region_cache_forward)
15763 (region_cache_backward, pp_cache):
15764 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15765 so that ptrdiff_t * can be passed to xpalloc.
15766 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15767 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15768 (pp_cache): Don't assume cache_len fits in int.
15769 * region-cache.h: Adjust extern decls to match.
15771 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15772 EMACS_INT, since either will do, for xpalloc.
15774 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15775 (xnmalloc, xnrealloc, xpalloc): New functions.
15777 * bidi.c (bidi_shelve_header_size): New constant.
15778 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15779 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15781 * bidi.c (bidi_cache_shrink):
15782 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15784 Don't update size of array until after memory allocation succeeds,
15785 because xmalloc/xrealloc may not return.
15786 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15787 now that we have proper integer overflow checking.
15788 (record_overlay_string, overlay_strings): Catch overflows when
15789 calculating size of overlay_str_buf.
15791 * callproc.c (Fcall_process): Check for size overflow when
15792 calculating size of args2.
15793 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15794 Normally we prefer signed values, but sticking with ptrdiff_t would
15795 require adding more-complicated checks.
15797 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15798 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15799 Redo buffer-overflow calculations to avoid integer overflow.
15800 Add a FIXME comment where memory seems to be over-allocated.
15802 * character.c (Fstring): Check for size-calculation overflow.
15804 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15805 unnecessary integer overflow. Check for size overflow.
15806 (encode_coding_object): Don't update size until xmalloc succeeds.
15808 * composite.c (get_composition_id): Check for overflow in glyph
15809 length calculations.
15811 Integer and memory overflow fixes for display code.
15812 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15813 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15814 (scrolling_window): Check for overflow in size calculations.
15815 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15816 Don't assume glyph table len fits in int.

15818 (row_table_size): Now ptrdiff_t, not int.
15819 (scrolling_window): Avoid overflow in size calculations.
15820 Don't update size until allocation succeeds.
15821 * fns.c (concat): Check for overflow in size calculations.
15822 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15823 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15826 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15827 (get_doc_string): Check for size calculation overflow.
15828 Don't update size until allocation succeeds.
15829 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15830 EMACS_INT, where ptrdiff_t will do.
15831 (Fsubstitute_command_keys): Check for string overflow.
15833 * editfns.c (set_time_zone_rule): Don't assume environment length
15835 (message_length): Now ptrdiff_t, not int.
15836 (Fmessage_box): Don't update size until allocation succeeds.
15837 Don't assume message length fits in int.
15838 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15840 * emacs.c (main): Do not reallocate argv, since there is a null at
15841 the end that can be overwritten, and this way there's no need to
15842 worry about size-calculation overflow.
15843 (sort_args): Check for size-calculation overflow.
15845 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15847 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15849 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15850 (x_set_scroll_bar_width, x_figure_window_size):
15851 Check for integer overflow.
15852 (x_set_alpha): Do not assume XINT fits in int.
15854 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15855 This is for the members text_lines, text_cols, total_lines, total_cols,
15856 where the system imposes an 'int' limit.
15858 * fringe.c (Fdefine_fringe_bitmap):
15859 Don't update size until alloc works.
15861 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15862 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15864 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15865 Check for size-calculation overflow.
15866 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15867 do, as we prefer signed integers.
15868 (id_to_widget.max_size, id_to_widget.used)
15869 (xg_store_widget_in_map, xg_remove_widget_from_map)
15870 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15871 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15872 Use and return ptrdiff_t, not int.
15873 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15874 * gtkutil.h: Change prototypes to match the above.
15876 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15877 are duplicate now that they've been promoted to lisp.h.
15878 (x_allocate_bitmap_record, x_alloc_image_color)
15879 (make_image_cache, cache_image, xpm_load):
15880 Don't update size until alloc is done.
15881 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15883 Check for size calculation overflow.
15884 (ct_colors_allocated_max): New constant.
15885 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15888 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15889 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15890 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15891 Use ptrdiff_t, not int, to count maps.
15892 (read_char_minibuf_menu_prompt): Check for overflow in size
15893 calculations. Don't update size until allocation succeeds.
15894 Redo calculations to avoid overflow.
15895 * keyboard.h: Change prototypes to match the above.
15897 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15899 (current_minor_maps): Check for size calculation overflow.
15900 * keymap.h: Change prototypes to match the above.
15902 * lread.c (read1, init_obarray): Don't update size until alloc done.
15904 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15905 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15907 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15908 Now ptrdiff_t, not int.
15909 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15913 in size calculation.
15915 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15917 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15918 overflow. Don't bother calling xmalloc when xrealloc will do.
15920 * search.c (Freplace_match): Check for size calculation overflow.
15921 (Fset_match_data): Don't assume list lengths fit in 'int'.
15923 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15924 for command line length. Do not attempt to address one before the
15925 beginning of an array, as that's not portable.
15927 * term.c (max_frame_lines): Remove; unused.
15928 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15930 (encode_terminal_code, calculate_costs): Check for size
15931 calculation overflow.
15932 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
15933 table lengths and related sizes. Don't update size until alloc
15934 done. Redo calculations to avoid overflow.
15935 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15937 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15938 subtracting pointers.
15939 (gobble_line): Check for overflow more carefully. Don't update size
15942 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15943 Don't update size until alloc done.
15944 Redo size calculations to avoid overflow.

15949 Use ptrdiff_t, not int, for sizes.
15950 (store_mode_line_noprop_char): Don't update size until alloc done.
15952 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
15953 Use ptrdiff_t, not int, for sizes.
15954 (Finternal_make_lisp_face, cache_face):
15955 Check for size calculation overflow.
15956 (cache_face): Treat size calculation overflows as if they were
15957 memory exhaustion (the usual treatment), rather than aborting.
15959 * xfns.c (x_encode_text, x_set_name_internal)
15960 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15961 sizes, since they can exceed INT_MAX in size. Check for size
15962 calculation overflow.
15964 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15965 (xg_select): Check for size calculation overflow.
15966 Don't update size until alloc done.
15968 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15969 as sprintf is limited to int lengths.
15971 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15972 (X_LONG_MIN): New macros.
15973 Use them to make the following changes clearer.
15974 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15975 This change doesn't affect the value now, but it may help remind
15976 future maintainers not to raise the value too much later.
15977 (SELECTION_QUANTUM): Remove, replacing with ...
15978 (selection_quantum): ... new function, which avoids overflow.
15980 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15981 assumption that selection length fits in 'int'.
15982 (x_reply_selection_request, x_handle_selection_request)
15983 (x_get_window_property, receive_incremental_selection)
15984 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15985 (lisp_data_to_selection_data, clean_local_selection_data):
15986 Use ptrdiff_t, not int, to record length of selection.
15987 (x_reply_selection_request, x_get_window_property)
15988 (receive_incremental_selection, x_property_data_to_lisp):
15989 Redo calculations to avoid overflow.
15990 (x_reply_selection_request): When sending hint, ceiling it at
15991 X_LONG_MAX rather than relying on wraparound overflow to send
15993 (x_get_window_property, receive_incremental_selection)
15994 (lisp_data_to_selection_data, x_property_data_to_lisp):
15995 Check for size-calculation overflow.
15996 (x_get_window_property, receive_incremental_selection)
15997 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15998 Don't store size until memory allocation succeeds.
15999 (x_get_window_property): Plug memory leak on memory exhaustion.
16000 Don't double-block input; malloc is safe here. Don't assume 2**34
16001 - 4 fits in unsigned long. Add an xassert to check
16002 XGetWindowProperty overflow. Be more careful about overflow
16003 calculations, and distinguish size from memory overflow better.
16004 (receive_incremental_selection): When tracing, don't assume
16005 unsigned int is less than INT_MAX.
16006 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16007 harmful) conversions of unsigned short to int.
16008 (lisp_data_to_selection_data): Don't assume that integers
16009 in the range -65535 through -1 fit in an X unsigned short.
16010 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16011 result parameters unless successful. Rely on cons_to_unsigned
16012 to report problems with elements; the old code wasn't right anyway.
16013 (x_check_property_data): Check for int overflow; we cannot use
16014 a wider type due to X limits.
16015 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16017 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

16047 * lisp.h (hash_lookup, hash_put):
16048 * minibuf.c (Ftest_completion):
16049 Use ptrdiff_t for hash table indexes, not int (which is too
16050 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16051 32-bit --with-wide-int hosts).
16053 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16054 Add a FIXME comment about memory leaks.

16059 * character.h (CHAR_WIDTH):
16060 * indent.c (MULTIBYTE_BYTES_WIDTH):
16061 Use sanitize_char_width to avoid undefined and/or bad behavior
16062 with outlandish widths.
16063 * character.h (sanitize_tab_width): Rename from sanitize_width,
16064 now that we have two such functions. All uses changed.

16082 * xterm.c: Don't go over XClientMessageEvent limit.
16083 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16084 (x_send_scroll_bar_event): Likewise. Check that the size does not
16085 exceed limits imposed by XClientMessageEvent, as well as the usual
16086 ptrdiff_t and size_t limits.
16088 * keyboard.c: Overflow, signedness and related fixes.
16089 (make_lispy_movement): Use same integer type in forward decl
16090 that is used in the definition.
16091 (read_key_sequence, keyremap_step):
16092 Change bufsize argument back to int, undoing my 2011-03-30 change.
16093 We prefer signed types, and int is wide enough here.
16094 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16095 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16096 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16097 length, not size_t. Use ptrdiff_t for index, not int.
16098 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16099 possibility of integer overflow.

16125 since parse_image_check makes sure they fit into int.
16126 (png_load, gif_load, svg_load_image):
16127 Prefer int to unsigned where either will do.
16128 (tiff_handler): New function, combining the cores of the
16129 old tiff_error_handler and tiff_warning_handler.
16130 This function is rewritten to use vsnprintf and thereby avoid
16131 stack buffer overflows. It uses only the features of vsnprintf
16132 that are common to both POSIX and native Microsoft.
16133 (tiff_error_handler, tiff_warning_handler): Use it.
16134 (tiff_load, gif_load, imagemagick_load_image):
16135 Don't assume :index value fits in 'int'.
16136 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16137 (imagemagick_load_image): Check that crop parameters fit into
16138 the integer types that MagickCropImage accepts. Don't assume
16139 Vimagemagick_render_type has a nonnegative value. Don't assume
16140 size_t fits in 'long'.
16141 (gs_load): Use printmax_t to print the widest integers possible.

16155 (handle_single_display_spec): If the display spec is of the form
16156 `(space ...)', and specifies display in the text area, return 2
16158 (try_cursor_movement): Check for the need to scroll more
16159 accurately, and prefer exact match for point under bidi.
16160 Don't advance `row' beyond the last row of the window.
16162 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16163 into disp_prop; all users changed.

16177 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16178 buffers, return left-to-right.
16179 (set_cursor_from_row): Consider candidate row a win if its glyph
16180 represents a newline and point is on that newline. Fixes cursor
16181 positioning on the newline at EOL of R2L text within L2R
16182 paragraph, and vice versa.
16183 (try_cursor_movement): Check continued rows, in addition to
16184 continuation rows. Fixes unwarranted scroll when point enters a
16185 continued line of R2L text within an L2R paragraph, or vice versa.
16186 (cursor_row_p): Consider the case of point being equal to
16187 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16188 from the end of a short line to the beginning of a continued line
16189 of R2L text within L2R paragraph.
16190 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

16211 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16213 * xdisp.c (redisplay_window): When computing centering_position,
16214 account for the height of the header line. (Bug#8874)
16216 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16217 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16218 candidate is selected by the mouse, and that candidate has a
16219 composed character under the mouse.
16221 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16222 coordinates reported by pos-visible-in-window-p for a composed
16223 character in column zero.
16225 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16231 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16232 consider it a hit if to_charpos is anywhere in the range of the
16233 composed buffer positions.
16235 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16237 * image.c (gif_load): Don't assume that each subimage has the same
16238 dimensions as the base image. Handle disposal method that is
16239 "undefined" by the gif spec (Bug#9335).
16241 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16243 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16248 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16249 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16250 from an Org mode buffer to a Speedbar frame.
16252 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16253 a composition, take its buffer position from IT->cmp_it.charpos.
16254 Fixes cursor positioning at the beginning of a line that begins
16255 with a composed character.
16257 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16259 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16260 character bidirectional type, use STRONG_L instead. Fixes crashes
16261 in a buffer produced by `describe-categories'.
16263 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16264 members before the level stack, so they would be saved and
16265 restored when copying iterator state. Fixes incorrect reordering
16266 around TABs covered by display properties.
16268 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16270 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16336 after the pid of the process is set to -1 (Bug#8162).
16338 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16340 * xdisp.c (move_it_in_display_line_to): Don't invoke
16341 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16342 ppos_it. Fixes vertical cursor motion when line beginning is
16343 covered by an image. (Bug#9296)
16345 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16347 * nsterm.h (ns_run_ascript): Declare.

16351 (ns_run_ascript): New function.
16352 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16353 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16354 the event loop. Get status from as_status (Bug#7276).
16356 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16357 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16358 the event loop (Bug#7276).
16360 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

16383 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16384 (Fnetwork_interface_list): Allocate in increments of bytes instead
16385 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16386 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16388 (struct ifflag_def): notrailers is smart on OSX.
16389 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16390 Get hardware address with getifaddrs if available.
16392 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16394 * xdisp.c (iterate_out_of_display_property): xassert that
16395 IT->position is set to within IT->object's boundaries. Break from
16396 the loop as soon as EOB is reached; avoids infloops in redisplay
16397 when IT->position is set up wrongly due to some bug.
16398 Set IT->current to match the bidi iterator unconditionally.
16399 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16400 entry. Force push_it to save on the stack the current
16401 buffer/string position, to be restored by pop_it. Fix flags in
16402 the iterator structure wrt the object coming from a display
16403 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16404 properties. (Bug#9284)
16406 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16408 * fontset.c (fontset_get_font_group): Add proper type checks.

16421 no-display-properties-and-no-overlays under bidi display.
16422 Set disp_pos in the bidi iterator to avoid searches for display
16423 properties and overlays.
16425 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16427 * editfns.c (Fset_time_zone_rule): Document relationship with the

16433 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16435 * composite.c (autocmp_chars): Don't reset point. That is done by
16436 restore_point_unwind (Bug#5984).
16438 2011-08-07 Juri Linkov <juri@jurta.org>
16440 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16441 to show the arg `TIME' instead of `TIMEVAL'.
16443 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16445 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16446 display property strides EOL and includes a newline, as in
16447 longlines-mode. (Bug#9254)
16448 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16449 word-wrap under bidirectional display. (Bug#9224)
16451 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16452 is non-zero, even if the data buffer is NULL. Fixes a crash in
16453 vertical-motion with longlines-mode. (Bug#9254)
16455 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16457 * bidi.c <bidi_cache_total_alloc>: Now static.

16460 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16463 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16464 amount allocated this far in `bidi_cache_total_alloc'.
16465 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16466 non-zero, only free the data buffer without restoring the cache
16467 contents. All callers changed.
16469 * dispextern.h (bidi_unshelve_cache): Update prototype.
16471 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16472 (move_it_in_display_line, move_it_to)
16473 (move_it_vertically_backward, move_it_by_lines): Replace the call
16474 to xfree to an equivalent call to bidi_unshelve_cache.
16475 (move_it_in_display_line_to): Fix logic of returning
16476 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16478 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16480 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16481 came from a string character with a `cursor' property. (Bug#9229)
16483 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16485 * Makefile.in (LIB_PTHREAD): New variable.
16486 (LIBES): Add LIB_PTHREAD (Bug#9216).
16488 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16489 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16491 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16493 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16495 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16497 * xterm.c (x_find_topmost_parent): New function.
16498 (x_set_frame_alpha): Find topmost parent window with
16499 x_find_topmost_parent and set the property there also (bug#9181).
16500 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16502 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16504 * callproc.c (Fcall_process): Avoid vfork clobbering
16505 the local vars buffer, coding_systems, current_dir.
16507 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16509 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16511 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16513 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16514 so that it is not optimized away.
16516 * xdisp.c (compute_display_string_pos): Remove unused local.
16518 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16520 Fix slow cursor motion and scrolling in large buffers with
16521 selective display, like Org Mode buffers. (Bug#9218)
16523 * dispextern.h (struct bidi_it): New member disp_prop_p.
16525 * xdisp.c: Remove one-slot cache of display string positions.
16526 (compute_display_string_pos): Accept an additional argument
16527 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16528 for a display string or property. If found, set DISP_PROP_P
16531 * bidi.c (bidi_fetch_char): Accept an additional argument
16532 DISP_PROP_P, and pass it to compute_display_string_pos.
16533 Only handle text covered by a display string if DISP_PROP_P is returned
16534 non-zero. All callers of bidi_fetch_char changed.
16536 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16538 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16540 2010-12-03 Don March <don@ohspite.net>
16542 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16543 last character M-[char] is translated to ESC [char] (bug#7541).
16545 2011-08-02 Kenichi Handa <handa@m17n.org>
16547 * lisp.h (uniprop_table): Extern it.
16549 * chartab.c (uniprop_table): Make it non-static.
16551 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16553 * xdisp.c (forward_to_next_line_start): Accept additional argument
16554 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16556 (reseat_at_next_visible_line_start): Use the bidi iterator state
16557 returned by forward_to_next_line_start to restore the state of
16558 it->bidi_it after backing up to previous newline. (Bug#9212)
16560 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16562 * regex.c (re_comp): Protoize.
16563 (re_exec): Fix return type.
16564 (regexec): Fix type of `ret'. (Bug#9203)
16566 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16568 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16569 This is needed if max-image-size is a floating-point number.
16571 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16573 * print.c (print_object): Print empty symbol as ##.
16575 * lread.c (read1): Read ## as empty symbol.
16577 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16579 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16580 setting frame foreground color (Bug#9175).
16581 (x_set_background_color): Likewise.
16583 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16584 contents (Bug#9176).
16585 (EmacsTooltip -init): Remove bezels and add shadows to
16588 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16589 or scroll bar (Bug#8470).
16591 * nsfont.m (nsfont_open): Remove assignment to voffset and
16592 unnecessary vars hshink, expand, hd, full_height, min_height.
16593 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16595 * nsterm.h (nsfont_info): Remove voffset field.
16597 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16599 Implement strike-through and overline on NextStep (Bug#8863).
16601 * nsfont.m (nsfont_open): Use underline position provided by font,
16602 instead of hard-coded value of 2.
16603 (nsfont_draw): Call ns_draw_text_decoration instead.
16605 * nsterm.h: Add declaration for ns_draw_text_decoration.
16607 * nsterm.m (ns_draw_text_decoration): New function for drawing
16608 underline, overline, and strike-through.
16609 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16610 ns_draw_text_decoration. Change treatment of cursor drawing to
16611 accommodate underlining, etc.
16613 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16615 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16618 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16620 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16621 Without this fix, if a signal arrives just after memory fills up,
16622 'malloc' might be invoked reentrantly.
16624 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16625 In other words, assume that every image size is allowed, on non-X
16626 hosts. This assumption is probably wrong, but it lets Emacs compile.
16628 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16630 * regex.c (re_iswctype): Convert return values to boolean.
16632 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16634 * xdisp.c (compute_display_string_pos): Don't use cached display
16635 string position if the buffer had its restriction changed.
16638 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16640 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16642 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16644 Integer signedness and overflow and related fixes. (Bug#9079)
16646 * bidi.c: Integer size and overflow fixes.
16647 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16648 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16649 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16650 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16651 (bidi_find_other_level_edge):
16652 Use ptrdiff_t instead of EMACS_INT where either will do.
16653 This works better on 32-bit hosts configured --with-wide-int.
16654 (bidi_cache_ensure_space): Check for size-calculation overflow.
16655 Use % rather than repeated addition, for better worst-case speed.
16656 Don't set bidi_cache_size until after xrealloc returns, because it
16658 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16659 (bidi_cache_ensure_space): Also check that the bidi cache size
16660 does not exceed that of the largest Lisp string or buffer. See Eli
16661 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16663 * alloc.c (__malloc_size_t): Remove.
16664 All uses replaced by size_t. See Andreas Schwab's note
16665 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16667 * image.c: Improve checking for integer overflow.
16668 (check_image_size): Assume that f is nonnull, since
16669 it is always nonnull in practice. This is one less thing to
16670 worry about when checking for integer overflow later.
16671 (x_check_image_size): New function, which checks for integer
16672 overflow issues inside X.
16673 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16674 This removes the need for a memory_full check.
16675 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16676 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16677 (xbm_read_bitmap_data): Change locals back to 'int', since
16678 their values must fit in 'int'.
16679 (xpm_load_image, png_load, tiff_load):
16680 Invoke x_create_x_image_and_pixmap earlier,
16681 to avoid much needless work if the image is too large.
16682 (tiff_load): Treat overly large images as if
16683 x_create_x_image_and_pixmap failed, not as malloc failures.
16684 (gs_load): Use x_check_image_size.
16686 * gtkutil.c: Omit integer casts.
16687 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16688 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16690 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16692 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16693 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16694 would wrongly return t on a 64-bit host.
16696 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16697 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16698 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16699 and therefore cause GCC to emit a bogus diagnostic in some cases.
16701 * image.c: Integer signedness and overflow and related fixes.
16702 This is not an exhaustive set of fixes, but it's time to
16703 record what I've got.
16704 (lookup_pixel_color, check_image_size): Remove redundant decls.
16705 (check_image_size): Don't assume that arbitrary EMACS_INT values
16706 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16707 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16708 (tiff_load, imagemagick_load_image):
16709 Check for overflow in size calculations.
16710 (x_create_x_image_and_pixmap): Remove unnecessary test for
16711 xmalloc returning NULL; that can't happen.
16712 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16713 (xpm_color_bucket): Use better integer hashing function.
16714 (xpm_cache_color): Don't possibly over-allocate memory.
16715 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16716 (gif_memory_source):
16717 Use ptrdiff_t, not int or size_t, to record sizes.
16718 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16719 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16720 either works, as we prefer signed integers.
16721 (tiff_read_from_memory, tiff_write_from_memory):
16722 Return tsize_t, not size_t, since that's what the TIFF API wants.
16723 (tiff_read_from_memory): Don't fail simply because the read would
16724 go past EOF; instead, return a short read.
16725 (tiff_load): Omit no-longer-needed casts.
16726 (Fimagemagick_types): Don't assume size fits into 'int'.
16728 Improve hashing quality when configured --with-wide-int.
16729 * fns.c (hash_string): New function, taken from sxhash_string.
16730 Do not discard information about ASCII character case; this
16731 discarding is no longer needed.
16732 (sxhash-string): Use it. Change sig to match it. Caller changed.
16733 * lisp.h: Declare it.
16734 * lread.c (hash_string): Remove, since we now use fns.c's version.
16735 The fns.c version returns a wider integer if --with-wide-int is
16736 specified, so this should help the quality of the hashing a bit.
16738 * emacs.c: Integer overflow minor fix.
16739 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16740 Define only if GNU_LINUX.
16741 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16743 * dispnew.c: Integer signedness and overflow fixes.
16744 Remove unnecessary forward decls, that were a maintenance hassle.
16745 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16747 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16748 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16749 (prepare_desired_row, line_draw_cost):
16750 Use int, not unsigned, where either works.
16751 (save_current_matrix, restore_current_matrix):
16752 Use ptrdiff_t, not size_t, where either works.
16753 (init_display): Check for overflow more accurately, and without
16754 relying on undefined behavior.
16756 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16757 Remove, replacing with the new symbols in lisp.h. All uses changed.
16758 * fileio.c (make_temp_name):
16759 * filelock.c (lock_file_1, lock_file):
16760 * xdisp.c (message_dolog):
16761 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16762 Use pMd etc. instead.
16763 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16764 replacing the pWIDE etc. symbols removed from editfns.c.
16766 * keyboard.h (num_input_events): Now uintmax_t.
16767 This is (very slightly) less likely to mess up due to wraparound.
16770 * buffer.c: Integer signedness fixes.
16771 (alloc_buffer_text, enlarge_buffer_text):
16772 Use ptrdiff_t rather than size_t when either will do, as we prefer
16775 * alloc.c: Integer signedness and overflow fixes.
16776 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16777 (__malloc_size_t): Default to size_t, not to int.
16778 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16779 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16780 Prefer ptrdiff_t to size_t when either would do, as we prefer
16782 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16783 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16784 Now const. Initialize with values that are in range even if char
16786 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16787 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16788 These functions do the right thing with sizes > 2**32.
16789 (check_depth): Now ptrdiff_t, not int.
16790 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16791 Adjust to new way of storing sizes. Check for size overflow bugs
16793 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16794 slightly wrong anyway, as it missed one instance of
16795 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16796 (refill_memory_reserve): Omit needless cast to size_t.
16797 (mark_object_loop_halt): Mark as externally visible.
16799 * xselect.c: Integer signedness and overflow fixes.
16800 (Fx_register_dnd_atom, x_handle_dnd_message):
16801 Use ptrdiff_t, not size_t, since we prefer signed.
16802 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16803 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16804 x_dnd_atoms_size and x_dnd_atoms_length.
16806 * doprnt.c: Prefer signed to unsigned when either works.
16808 * doprnt.c (doprnt):
16810 * xdisp.c (vmessage):
16811 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16812 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16813 prefer signed arithmetic to avoid comparison confusion.
16814 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16815 but is a bit tricky.
16817 Assume freestanding C89 headers, string.h, stdlib.h.
16818 * data.c, doprnt.c, floatfns.c, print.c:
16819 Include float.h unconditionally.
16820 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16821 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16822 * regex.c: Likewise for stddef.h, string.h.
16823 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16824 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16825 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16826 (STDC_HEADERS): Remove obsolete defines.
16827 * sysdep.c: Include limits.h unconditionally.
16829 Assume support for memcmp, memcpy, memmove, memset.
16830 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16831 * regex.c (memcmp, memcpy):
16832 Remove; we assume C89 now.
16834 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16835 (__malloc_safe_bcopy): Remove; no longer needed.
16837 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16838 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16839 well either way, and we prefer signed to unsigned.
16841 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16843 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16844 closes the connection while we're reading (bug#9182).
16846 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16848 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16849 are specified (Bug#9168).
16851 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16853 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16854 Found by GCC static checking and --with-wide-int on a 32-bit host.
16856 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16858 * xdisp.c (compute_display_string_pos): Fix logic of caching
16859 previous display string position. Initialize cached_prev_pos to
16860 -1. Fixes slow-down at the beginning of a buffer.
16862 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16864 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16865 for attrs[LFACE_FONTSET_INDEX].
16867 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16869 * xml.c (parse_region): Remove unused local
16870 that was recently introduced.
16872 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16874 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16875 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16877 * xdisp.c (move_it_in_display_line_to): Record the best matching
16878 position for TO_CHARPOS while scanning the line, and restore it on
16879 exit if none of the characters scanned was an exact match.
16880 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16881 when exact match is impossible due to invisible text, and the
16882 lines are truncated.
16884 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16886 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16889 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16891 Fix a significant slow-down of cursor motion with C-n, C-p,
16892 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16893 auto-repeat under bidi redisplay in fontified buffers.
16894 * xdisp.c (compute_stop_pos_backwards): New function.
16895 (next_element_from_buffer): Call compute_stop_pos_backwards to
16896 find a suitable prev_stop when we find ourselves before
16898 (reseat): Don't look for prev_stop, as that could mean a very long
16900 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16901 <cached_disp_overlay_modiff>: Cache for last found display string
16903 (compute_display_string_pos): Return the cached position if asked
16904 about the same buffer in the same area of character positions, and
16905 the buffer wasn't changed since the time the display string
16906 position was cached.
16908 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16910 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16911 is an integer, which is important for empty lines. (Bug#9149)
16913 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16915 * frame.c (Fmodify_frame_parameters): In tty case, update the
16916 default face if necessary (Bug#4238).
16918 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16920 * editfns.c (Fstring_to_char): No need to explain what a character
16921 is in the docstring (Bug#6576).
16923 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16925 * xml.c (parse_region): Make sure we always return a tree.
16927 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16929 * xml.c (parse_region): If a document contains only comments,
16932 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16934 * xml.c (make_dom): Return comments, too.

16939 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16940 and the surrounding thread.
16941 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16942 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16943 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16945 * s/openbsd.h (BROKEN_SIGIO): Define.
16946 * unexelf.c (unexec) [__OpenBSD__]:
16947 Don't update the .mdebug section of the Alpha COFF symbol table.
16949 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16951 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16954 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16956 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16957 This fixes some race conditions on the permissions of any newly
16960 * alloc.c (valid_pointer_p): Use pipe, not open.
16961 This fixes some permissions issues when debugging.
16963 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16964 If fchown fails to set both uid and gid, try to set just gid,
16965 as that is sometimes allowed. Adjust the file's mode to eliminate
16966 setuid or setgid bits that are inappropriate if fchown fails.
16968 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16970 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16982 symbol character follows.
16984 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16986 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16987 This works around a problem with the previous change to Fcopy_file.
16988 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16989 and without this change, GCC might complain about discarding
16990 fchown's return value.
16992 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16994 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16996 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16998 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17000 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17002 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17003 it's used from the C level.
17005 * process.c: Use the same condition for POLL_FOR_INPUT in both
17006 keyboard.c and process.c (bug#1858).

17010 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17011 (Fgnutls_boot): Use it.

17015 * doc.c (Fsubstitute_command_keys): Revert last change.
17017 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17019 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17020 quotes the next character, and doesn't affect other longer
17021 sequences (bug#8935).
17023 * lread.c (syms_of_lread): Clarify that is isn't only
17024 `eval-buffer' and `eval-defun' that's affected by
17025 `lexical-binding' (bug#8460).
17027 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17029 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17030 bidi redisplay when a line includes both an image and is truncated.
17032 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17034 Fix minor problems found by static checking.
17035 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17036 (elsz): Now a signed constant, not a size_t var. We prefer signed
17037 types to unsigned, to avoid integer comparison confusion. Without
17038 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17039 "cannot optimize loop, the loop counter may overflow", a symptom
17041 * indent.c (Fvertical_motion): Mark locals as initialized.
17042 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17044 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

17070 (display_string): If we need to ignore text properties of
17071 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17072 original value of -1 will not work with bidi.)
17073 (compute_display_string_pos): First arg is now struct
17074 `text_pos *'; all callers changed. Support display properties on
17076 (compute_display_string_end): Support display properties on Lisp
17078 (init_iterator, reseat_1, reseat_to_string): Initialize the
17079 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17080 when iterating on a string not from display properties).
17081 (compute_display_string_pos, compute_display_string_end):
17082 Fix calculation of the object to scan. Fixes an error when using
17084 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17085 base_level_stop; instead, set base_level_stop to BEGV.
17086 Fixes crashes in vertical-motion.
17087 (next_element_from_buffer): Improve commentary for when
17088 the iterator is before prev_stop.
17089 (init_iterator): Initialize bidi_p from the default value of
17090 bidi-display-reordering, not from buffer-local value. Use the
17091 buffer-local value only if initializing for buffer iteration.

17112 parts of next_element_from_buffer, next_element_from_string, and
17113 next_element_from_c_string.
17114 (tool_bar_lines_needed, redisplay_tool_bar)
17115 (display_menu_bar): Force left-to-right direction. Add a FIXME
17116 comment for making that be controlled by a user option.

17126 iterator for displaying display or overlay strings.
17127 (forward_to_next_line_start): Don't use the shortcut if
17129 (back_to_previous_visible_line_start): If handle_display_prop
17130 pushed the iterator stack, restore the internal state of the bidi
17131 iterator by calling bidi_pop_it same number of times.
17132 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17133 and we are bidi-iterating, don't decrement the iterator position;
17134 instead, set the first_elt flag in the bidi iterator, to produce
17136 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17137 (push_display_prop): xassert that we are iterating a buffer.
17138 (push_it, pop_it): Save and restore paragraph_embedding member.
17139 (handle_single_display_spec, next_overlay_string)
17140 (get_overlay_strings_1, reseat_1, reseat_to_string)
17141 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17142 correctly. Don't assume unibyte strings are not bidi-reordered.

17151 property. Fix a typo in popping stretch info. Add an assertion
17152 for verifying that the iterator position is in sync with the bidi
17154 (handle_single_display_spec, get_overlay_strings_1)

17299 The old code sometimes used this field without initializing it.
17301 * alloc.c (gc_sweep): Don't read past end of array.
17302 In theory, the old code could also have corrupted Emacs internals,
17303 though it'd be very unlikely.

17307 * character.c (Fcharacterp): Don't advertise optional ignored
17308 argument. (Bug#4026)

17566 (clone_per_buffer_values): Don't assume that
17567 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
17568 This isn't true in general, and it's particularly not true
17569 if Emacs is configured with --with-wide-int.
17570 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17571 New macros, used in the buffer.c change.

17607 Random fixes. E.g., (random) never returned negative values.
17608 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17609 subseconds part to the entropy, as that's a bit more random.
17610 Prefer signed to unsigned, since the signedness doesn't matter and
17611 in general we prefer signed. When given a limit, use a
17612 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17613 latter isn't right if USE_2_TAGS_FOR_INTS.
17614 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17615 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17617 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17619 * textprop.c (text_property_stickiness):
17620 Obey Vtext_property_default_nonsticky.

17627 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17628 This is more efficient than Ffile_directory_p and avoids a minor race.
17630 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17632 * buffer.c (Foverlay_put): Say what the return value is
17635 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17636 is a directory before asking whether to use the file name
17638 (barf_or_query_if_file_exists): Make the "File is a directory"
17639 error be more correct.
17641 * fns.c (Frequire): Remove the mention of the .gz files, since
17642 that's installation-specific, but keep the mention of
17643 `get-load-suffixes'.
17645 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17647 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17655 Qgnutls_bootprop_verify_error (which is no longer used).
17657 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17658 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17659 Also (re)move comments that are misplaced or no longer relevant.

17684 leave any prefix arg for the up event (Bug#1586).
17686 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
17688 * lread.c (syms_of_lread): Mention single symbols defined by
17689 `defvar' or `defconst' (bug#7154).
17691 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17692 (Frequire): Mention get-load-suffixes.

17722 (syms_of_keymap): Defsubr make-composed-keymap.
17723 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17752 (xgselect_initialize): Ditto.
17754 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

17758 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
17760 * eval.c (struct backtrace): Simplify and port the data structure.
17761 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17762 signed bit field, as this assumption is not portable and it makes
17763 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17764 "char debug_on_exit : 1" as this is not portable either; instead,
17765 use the portable "unsigned int debug_on_exit : 1". Remove unused
17766 member evalargs. Remove obsolete comments about cc bombing out.
17768 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17862 Use gnulib's dup2 module instead of rolling our own.
17863 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17865 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17867 * dispnew.c (scrolling_window): Before scrolling, turn off a

17932 Integer and buffer overflow fixes (Bug#8873).
17934 * print.c (printchar, strout): Check for string overflow.
17935 (PRINTPREPARE, printchar, strout):
17936 Don't set size unless allocation succeeds.
17938 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17939 for sizes. Check for string overflow more accurately.
17940 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17942 * macros.c: Integer and buffer overflow fixes.
17943 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17944 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17948 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17950 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17952 * lread.c: Integer overflow fixes.
17953 (read_integer): Radix is now EMACS_INT, not int,
17954 to improve quality of diagnostics for out-of-range radices.
17955 Calculate buffer size correctly for out-of-range radices.
17956 (read1): Check for integer overflow in radices, and in
17957 read-circle numbers.
17958 (read_escape): Avoid int overflow.
17959 (Fload, openp, read_buffer_size, read1)
17960 (substitute_object_recurse, read_vector, read_list, map_obarray):

17976 2011-06-22 Leo Liu <sdl.web@gmail.com>
17978 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17979 Move to minibuffer.el.
17981 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17983 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17984 The following patches are for when GLYPH_DEBUG && !XASSERT.
17985 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17986 * dispnew.c (flush_stdout):
17987 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17988 Mark as externally visible.
17989 * dispnew.c (check_window_matrix_pointers): Now static.
17990 * dispnew.c (window_to_frame_vpos):
17991 * xfns.c (unwind_create_frame):
17992 * xterm.c (x_check_font): Remove unused local.
17993 * scroll.c (CHECK_BOUNDS):
17994 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17995 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17996 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17997 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17998 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18000 (debug_method_add): Use va_list and vsprintf rather than relying
18001 on undefined behavior with wrong number of arguments.
18002 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18003 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18004 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18005 since we're not interested in debugging glyphs with old libraries.
18006 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18007 GCC 4.6.0's static checking.
18009 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18011 Integer overflow and signedness fixes (Bug#8873).

18027 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18028 (.bitmaps_last, struct x_output.icon_bitmap):
18029 Use ptrdiff_t, not int, for bitmap indexes.
18030 (x_allocate_bitmap_record): Check for size overflow.
18031 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18033 Use ptrdiff_t, not int, for overlay counts.
18034 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18035 * editfns.c (overlays_around, get_pos_property):
18036 * textprop.c (get_char_property_and_overlay):
18037 * xdisp.c (next_overlay_change, note_mouse_highlight):
18038 * xfaces.c (face_at_buffer_position):
18039 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18040 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18041 (Fnext_overlay_change, Fprevious_overlay_change)
18042 (mouse_face_overlay_overlaps, Foverlays_in):
18043 Use ptrdiff_t, not int, for sizes.
18044 (overlays_at, overlays_in): Check for size-calculation overflow.
18046 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18048 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18049 (x_session_initialize): Do not assume string length fits in int.
18051 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18052 This is unlikely, but can occur if DPI is outlandish.
18054 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18055 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18057 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18058 * xrdb.c (magic_file_p, search_magic_path):
18059 Omit last arg SUFFIX; it was always 0. All callers changed.
18060 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18062 * xfont.c (xfont_match): Avoid need for strlen.
18064 * xfns.c: Don't assume strlen fits in int.

18067 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18068 not unsigned long, as we prefer signed integers. All callers changed.
18069 Detect integer overflow in repeat count.
18070 (message_dolog): Don't assume print length fits in 39 bytes.
18071 (display_mode_element): Don't assume strlen fits in int.
18073 * termcap.c: Don't assume sizes fit in int and never overflow.
18074 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18075 (gobble_line): Check for size-calculation overflow.
18077 * minibuf.c (Fread_buffer):
18078 * lread.c (intern, intern_c_string):
18079 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

18092 * filelock.c: Fix some buffer overrun and integer overflow issues.
18093 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18094 Reformulate so as not to need the command string.
18095 Invoke gzip -cd rather than gunzip, as it's more portable.
18096 (lock_info_type, lock_file_1, lock_file):
18097 Don't assume pid_t and time_t fit in unsigned long.
18098 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18099 (current_lock_owner): Prefer signed type for sizes.
18100 Use memcpy, not strncpy, where memcpy is what is really wanted.
18101 Don't assume (via atoi) that time_t and pid_t fit in int.
18102 Check for time_t and/or pid_t out of range, e.g., via a network share.
18103 Don't alloca where an auto var works fine.
18105 * fileio.c: Fix some integer overflow issues.
18106 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18107 Don't assume string length fits in int.
18108 (directory_file_name): Don't assume string length fits in long.
18109 (make_temp_name): Don't assume pid fits in int, or that its print
18110 length is less than 20.
18112 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18114 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18116 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

18129 (Fgetenv_internal):
18130 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18132 * lread.c (invalid_syntax): Omit length argument.
18133 All uses changed. This doesn't fix a bug, but it simplifies the
18134 code away from its former Hollerith-constant appearance, and it's
18135 one less 'int' to worry about when looking at integer-overflow issues.
18136 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18138 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18139 This didn't break anything, but it didn't help either.
18140 It's confusing to put a bogus integer in a place where the actual
18141 value does not matter.
18142 (LIST_END_P): Remove unused macro and its bogus comment.
18143 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18145 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18146 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18148 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18149 We prefer signed types, and the value cannot exceed the EMACS_INT
18150 range anyway (because otherwise the length would not be representable).
18151 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18152 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18153 This avoids a GCC warning when WIDE_EMACS_INT.
18155 * indent.c (sane_tab_width): New function.
18156 (current_column, scan_for_column, Findent_to, position_indentation)
18157 (compute_motion): Use it. This is just for clarity.
18158 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18160 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

18163 * composite.c (composition_gstring_put_cache):
18164 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18166 * editfns.c, insdel.c:
18167 Omit unnecessary forward decls, to simplify future changes.
18169 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18171 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18173 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18174 Use much-faster test for byte-length change.
18175 Don't assume string byte-length fits in 'int'.
18176 Check that character arg fits in 'int'.
18177 (mapcar1): Declare byte as byte, for clarity.
18179 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18181 * fns.c (concat): Catch string overflow earlier.
18182 Do not rely on integer wraparound.
18184 * dispextern.h (struct it.overlay_strings_charpos)
18185 (struct it.selective): Now EMACS_INT, not int.
18186 * xdisp.c (forward_to_next_line_start)
18187 (back_to_previous_visible_line_start)
18188 (reseat_at_next_visible_line_start, next_element_from_buffer):
18189 Don't arbitrarily truncate the value of 'selective' to int.
18191 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18193 * composite.c: Don't truncate sizes to 'int'.
18194 (composition_gstring_p, composition_reseat_it)
18195 (composition_adjust_point): Use EMACS_INT, not int.
18196 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18197 not EMACS_UINT, for indexes.
18199 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18201 * buffer.c: Include <verify.h>.
18202 (struct sortvec.priority, struct sortstr.priority):
18203 Now EMACS_INT, not int.
18204 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18205 (struct sortstr.size, record_overlay_string)
18206 (struct sortstrlist.size, struct sortlist.used):
18207 Don't truncate size to int.
18208 (record_overlay_string): Check for size-calculation overflow.
18209 (init_buffer_once): Check at compile-time, not run-time.
18211 2011-06-22 Jim Meyering <meyering@redhat.com>
18213 Don't leak an XBM-image-sized buffer
18214 * image.c (xbm_load): Free the image buffer after using it.
18216 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18219 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18220 that Sun C diagnosed.
18221 * fns.c (secure_hash): Fix pointer signedness issue.
18222 * intervals.c (static_offset_intervals): New function.
18223 (offset_intervals): Use it.
18225 2011-06-21 Leo Liu <sdl.web@gmail.com>
18228 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18231 * fns.c (secure_hash): Rename from crypto_hash_function and change
18232 the first arg to accept symbols.
18233 (Fsecure_hash): New primitive.
18234 (syms_of_fns): New symbols.
18236 2011-06-20 Deniz Dogan <deniz@dogan.se>
18238 * process.c (Fset_process_buffer): Clarify return value in
18241 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18243 * dispnew.c (add_window_display_history): Use BVAR.
18245 * xdisp.c (debug_method_add): Use BVAR.
18246 (check_window_end, dump_glyph_matrix, dump_glyph)
18247 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18249 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18252 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18253 check till after the cache is created in init_frame_faces.
18255 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18257 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18259 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18261 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18262 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18263 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18265 Improve buffer-overflow checking (Bug#8873).
18266 * fileio.c (Finsert_file_contents):
18267 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18268 Remove the old (too-loose) buffer overflow checks.
18269 They weren't needed, since make_gap checks for buffer overflow.
18270 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18271 The old code merely checked for Emacs fixnum overflow, and relied
18272 on undefined (wraparound) behavior. The new code avoids undefined
18273 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18275 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18276 Tune. Don't use wider integers than needed. Don't use alloca.
18277 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18279 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18281 * insdel.c, lisp.h (buffer_overflow): New function.
18282 (insert_from_buffer_1, replace_range, replace_range_2):
18283 * insdel.c (make_gap_larger):
18284 * editfns.c (Finsert_char):
18285 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18287 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18289 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18291 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18293 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18294 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18296 * fileio.c: Don't assume EMACS_INT fits in off_t.
18297 (emacs_lseek): New static function.
18298 (Finsert_file_contents, Fwrite_region): Use it.
18299 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18301 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18303 * fns.c: Don't overflow int when computing a list length.
18304 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18305 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18306 truncation on 64-bit hosts. Check for QUIT every
18307 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18308 faster and is responsive enough.
18309 (Flength): Report an error instead of overflowing an integer.
18310 (Fsafe_length): Return a float if the value is not representable
18311 as a fixnum. This shouldn't happen except in contrived situations.
18312 (Fnthcdr, Fsort): Don't assume list length fits in int.
18313 (Fcopy_sequence): Don't assume vector length fits in int.
18315 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18316 (header_size, word_size): New constants.
18317 (allocate_vectorlike): Don't check size overflow here.
18318 (allocate_vector): Check it here instead, since this is the only
18319 caller of allocate_vectorlike that could cause overflow.
18320 Check that the new vector's length is representable as a fixnum.
18322 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18323 The previous code was bogus. For example, next_almost_prime (32)
18324 returned 39, which is undesirable as it is a multiple of 3; and
18325 next_almost_prime (24) returned 25, which is a multiple of 5 so
18326 why was the code bothering to check for multiples of 7?
18328 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18330 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18332 Variadic C functions now count arguments with ptrdiff_t.
18333 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18334 Back then I didn't know that the Emacs coding style prefers signed int.
18335 Also, in the meantime I found a few more instances where arguments
18336 were being counted with int, which may truncate counts on 64-bit
18337 machines, or EMACS_INT, which may be unnecessarily wide.
18338 * lisp.h (struct Lisp_Subr.function.aMANY)
18339 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18340 Arg counts are now ptrdiff_t, not size_t.
18341 All variadic functions and their callers changed accordingly.
18342 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18343 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18344 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18345 * callint.c (Fcall_interactively): Check arg count for overflow,
18346 to avoid potential buffer overrun. Use signed char, not 'int',
18347 for 'varies' array, so that we needn't bother to check its size
18348 calculation for overflow.
18349 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18350 * eval.c (apply_lambda):
18351 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18352 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18353 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18355 * callint.c (Fcall_interactively): Don't use index var as event count.
18357 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18358 * mem-limits.h (SIZE): Remove; no longer used.
18360 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18362 Remove unnecessary casts.
18363 * xterm.c (x_term_init):
18364 * xfns.c (x_set_border_pixel):
18365 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18366 These aren't needed now that we assume ANSI C.
18368 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18369 It's more likely to cause problems (due to unsigned overflow)
18372 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18374 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18376 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18378 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18380 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18382 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18384 GLYPH_CODE_FACE returns EMACS_INT, not int.
18385 * dispextern.h (merge_faces):
18386 * xfaces.c (merge_faces):
18387 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18388 Don't assume EMACS_INT fits in int.
18390 * character.h (CHAR_VALID_P): Remove unused parameter.
18391 * fontset.c, lisp.h, xdisp.c: All uses changed.
18393 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18395 * fns.c (concat): Minor tuning based on overflow analysis.
18396 This doesn't fix any bugs. Use int to hold character, instead
18397 of constantly refetching from Emacs object. Use XFASTINT, not
18398 XINT, for value known to be a character. Don't bother comparing
18399 a single byte to 0400, as it's always less.
18401 * floatfns.c (Fexpt):
18402 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18404 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18407 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18409 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18410 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18411 incorrectly succeed when S was a string, because 4294967386 was
18412 truncated before it was used.
18414 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18415 Otherwise, an out-of-range integer could cause undefined behavior
18418 * composite.c: Use int, not EMACS_INT, for characters.
18419 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18420 EMACS_INT, for values that are known to be in character range.
18421 This doesn't fix any bugs but is the usual style inside Emacs and
18422 may generate better code on 32-bit machines.
18424 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18425 This is for reasons similar to the recent CHAR_STRING fix.
18426 * charset.c (Fencode_char): Check that character arg is actually
18427 a character. Pass an int to ENCODE_CHAR.
18428 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18429 wider than 'int', as a compile-time check to prevent future regressions
18432 * character.c (char_string): Remove unnecessary casts.
18434 Make sure a 64-bit char is never passed to CHAR_STRING.
18435 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18436 by silently ignoring the top 32 bits, allowing some values
18437 that were far too large to be valid characters.
18438 * character.h: Include <verify.h>.
18439 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18440 arguments are no wider than unsigned, as a compile-time check
18441 to prevent future regressions in this area.
18443 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18444 (Fsubst_char_in_region):
18446 * xdisp.c (decode_mode_spec_coding):
18447 Adjust to CHAR_STRING's new requirement.
18448 * editfns.c (Finsert_char, Fsubst_char_in_region):
18449 * fns.c (concat): Check that character args are actually
18450 characters. Without this test, these functions did the wrong
18451 thing with wildly out-of-range values on 64-bit hosts.
18453 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18454 These casts should not be needed on 32-bit hosts, either.
18455 * keyboard.c (read_char):
18456 * lread.c (Fload): Remove casts to unsigned.
18458 * lisp.h (UNSIGNED_CMP): New macro.
18459 This fixes comparison bugs on 64-bit hosts.
18460 (ASCII_CHAR_P): Use it.
18461 * casefiddle.c (casify_object):
18462 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18463 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18464 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18465 * dispextern.h (FACE_FROM_ID):
18466 * keyboard.c (read_char): Use UNSIGNED_CMP.
18468 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18469 not to EMACS_INT, to avoid GCC warning.
18471 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18473 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18474 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18475 isn't needed on 32-bit machines.
18477 * buffer.c (Fgenerate_new_buffer_name):
18478 Use EMACS_INT for count, not int.
18479 (advance_to_char_boundary): Return EMACS_INT, not int.
18481 * data.c (Qcompiled_function): Now static.
18483 * window.c (window_body_lines): Now static.
18485 * image.c (gif_load): Rename local to avoid shadowing.
18487 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18488 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18489 * alloc.c (make_save_value): Integer argument is now of type
18490 ptrdiff_t, not int.
18491 (mark_object): Use ptrdiff_t, not int.
18492 * lisp.h (pD): New macro.
18493 * print.c (print_object): Use it.
18495 * alloc.c: Use EMACS_INT, not int, to count objects.
18496 (total_conses, total_markers, total_symbols, total_vector_size)
18497 (total_free_conses, total_free_markers, total_free_symbols)
18498 (total_free_floats, total_floats, total_free_intervals)
18499 (total_intervals, total_strings, total_free_strings):
18500 Now EMACS_INT, not int. All uses changed.
18501 (Fgarbage_collect): Compute overall total using a double, so that
18502 integer overflow is less likely to be a problem. Check for overflow
18503 when converting back to an integer.
18504 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18505 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18506 These were 'int' variables that could overflow on 64-bit hosts;
18507 they were never used, so remove them instead of repairing them.
18508 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18509 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18510 Previously, this ceilinged at INT_MAX, but that doesn't work on
18512 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18514 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18515 (allocate_vectorlike): Check for ptrdiff_t overflow.
18516 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18517 when a (possibly-narrower) signed value would do just as well.
18518 We prefer using signed arithmetic, to avoid comparison confusion.
18520 * alloc.c: Catch some string size overflows that we were missing.
18521 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18522 for convenience in STRING_BYTES_MAX.
18523 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18524 The definition here is exact; the one in lisp.h was approximate.
18525 (allocate_string_data): Check for string overflow. This catches
18526 some instances we weren't catching before. Also, it catches
18527 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18528 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18529 and ptrdiff_t and EMACS_INT are both 64 bits.
18531 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18532 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18533 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18535 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18537 * alloc.c (Fmake_string): Check for out-of-range init.
18539 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18541 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18543 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18545 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18546 xg_get_default_scrollbar_width.
18548 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18549 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18550 (style_changed_cb): Call update_theme_scrollbar_width and call
18551 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18552 all frames (Bug#8505).
18553 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18554 Call gtk_window_set_resizable if HAVE_GTK3.
18555 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18556 and height if HAVE_GTK3 (Bug#8505).
18557 (scroll_bar_width_for_theme): New variable.
18558 (update_theme_scrollbar_width): New function.
18559 (xg_get_default_scrollbar_width): Move code to
18560 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18561 (xg_initialize): Call update_theme_scrollbar_width.
18563 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18565 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18567 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18569 * frame.c (make_frame): Call other_buffer_safely instead of
18572 * window.c (temp_output_buffer_show): Call display_buffer with
18573 second argument Vtemp_buffer_show_specifiers and reset latter
18574 immediately after the call.
18575 (Vtemp_buffer_show_specifiers): New variable.
18576 (auto_window_vscroll_p, next_screen_context_lines)
18577 (Vscroll_preserve_screen_position): Remove leading asterisks from
18580 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18582 Fix minor problems found by GCC 4.6.0 static checking.
18583 * buffer.c (Qclone_number): Remove for now, as it's unused.
18584 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18585 (record_buffer): Remove unused local.
18586 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18587 (set_frame_buffer_list): Remove; unused.
18588 * frame.h (other_visible_frames): Remove decl.
18589 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18590 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18591 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18593 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18594 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18595 Define only if HAVE_GPM.
18596 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18597 (update_hints_inhibit): Remove; never set. All uses removed.
18598 * widgetprv.h (emacsFrameClassRec): Remove decl.
18599 * window.c (delete_deletable_window): Now returns void, since it
18600 wasn't returning anything.
18601 (compare_window_configurations): Remove unused locals.
18602 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18603 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18604 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18605 the same widths as pointers. This follows up on the 2011-05-06 patch.
18606 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18607 * xterm.h: Likewise.
18608 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18610 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18612 * makefile.w32-in: Update dependencies.
18613 (LISP_H): Add lib/intprops.h.
18615 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18617 * image.c (gif_load): Add animation frame delay to the metadata.
18618 (syms_of_image): Use DEFSYM. New symbol `delay'.
18620 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18622 * window.c (delete_deletable_window): Re-add.
18623 (Fset_window_configuration): Rewrite to handle dead buffers and
18624 consequently deletable windows.
18625 (window_tree, Fwindow_tree): Remove. Supply functionality in
18627 (compare_window_configurations): Simplify code.
18629 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18631 * image.c (imagemagick_load_image): Fix type mismatch.
18632 (Fimagemagick_types): Likewise.
18634 * window.h (replace_buffer_in_windows): Declare.
18636 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18638 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18639 Qclone_number. Remove external declaration of Qdelete_window.
18640 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18642 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18643 Run Qbuffer_list_update_hook if allowed.
18644 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18645 buffer list implementation.
18646 (other_buffer_safely): New function.
18647 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18648 calls to replace_buffer_in_windows and
18649 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18651 (record_buffer): Inhibit quitting and rewrite using quittable
18652 functions. Run Qbuffer_list_update_hook if allowed.
18653 (Frecord_buffer, Funrecord_buffer): New functions.
18654 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18655 Move switch-to-buffer to window.el.
18656 (bury-buffer): Move to window.el.
18657 (Vbuffer_list_update_hook): New variable.
18659 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18662 * window.h (resize_frame_windows): Move up in code.
18663 (Fwindow_frame): Remove EXFUN.
18664 (replace_buffer_in_all_windows): Remove prototype.
18665 (replace_buffer_in_windows_safely): Add prototype.

19115 it to initialize the frame_window_p member of struct bidi_it.
19116 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19117 (bidi_resolve_explicit, bidi_resolve_weak)
19118 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
19119 bidi_it->nchars is non-positive.
19120 (bidi_level_of_next_char): Don't try to lookup the cache for the
19121 next/previous character if nothing is cached there yet, or if we
19122 were just reseat()'ed to a new position.
19124 * xdisp.c (set_cursor_from_row): Set start and stop points
19125 according to the row's direction when priming the loop that looks
19126 for the glyph on which to display cursor.
19127 (single_display_spec_intangible_p): Function deleted.
19128 (display_prop_intangible_p): Reimplement to call
19129 handle_display_spec instead of single_display_spec_intangible_p.
19130 Accept 3 additional arguments needed by handle_display_spec.
19131 This fixes incorrect cursor motion across display property with complex
19132 values: lists, `(when COND...)' forms, etc.
19133 (single_display_spec_string_p): Support property values that are
19134 lists with the argument STRING its top-level element.
19135 (display_prop_string_p): Fix the condition for processing a
19136 property that is a list to be consistent with handle_display_spec.
19137 (handle_display_spec): New function, refactored from the
19138 last portion of handle_display_prop.
19139 (compute_display_string_pos): Accept additional argument
19140 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19141 value of a `display' property is a "replacing spec".
19142 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19143 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19144 the display property, but just return a value indicating whether
19145 the display property will replace the characters it covers.
19146 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19147 frame_window_p members of struct bidi_it.
19148 (compute_display_string_pos, compute_display_string_end):
19150 (push_it): Accept second argument POSITION, where pop_it should
19151 jump to continue iteration.
19152 (reseat_1): Initialize bidi_it.disp_pos.
19154 * keyboard.c (adjust_point_for_property): Adjust the call to
19155 display_prop_intangible_p to its new signature.
19157 * dispextern.h (struct bidi_it): New member frame_window_p.
19158 (bidi_init_it): Update prototypes.
19159 (display_prop_intangible_p): Update prototype.
19160 (compute_display_string_pos, compute_display_string_end):
19161 Declare prototypes.

19167 Malloc failure behavior now depends on size of allocation.
19168 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19169 * lisp.h: Change signatures accordingly.
19170 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19171 All callers changed. (Bug#8762)
19173 * gnutls.c: Use Emacs's memory allocators.
19174 Without this change, the gnutls library would invoke malloc etc.
19175 directly, which causes problems on non-SYNC_INPUT hosts, and which
19176 runs afoul of improving memory_full behavior. (Bug#8761)
19177 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19178 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19179 xfree instead of the default malloc, realloc, free.
19180 (Fgnutls_boot): No need to check for memory allocation failure,
19181 since xmalloc does that for us.
19183 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19184 * category.c (hash_get_category_set):
19185 * ccl.c (ccl_driver):

19197 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19198 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19199 * image.c (make_image, search_image_cache, lookup_image)
19200 (xpm_put_color_table_h):
19201 * lisp.h (struct Lisp_Hash_Table):
19202 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19203 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19204 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19205 * alloc.c (allocate_vectorlike):
19206 Check for overflow in vector size calculations.
19207 * ccl.c (ccl_driver):
19208 Check for overflow when converting EMACS_INT to int.
19209 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19210 need to be updated by these changes.
19211 * fns.c (make_hash_table, maybe_resize_hash_table):
19212 Check for integer overflow with large hash tables.
19213 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19214 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19215 (SXHASH_REDUCE): New macro.
19216 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19217 Use it instead of discarding useful hash info with large hash values.
19218 (sxhash_float): New function.
19219 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19220 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19221 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19222 Rewrite to use FIXNUM_BITS, as this simplifies things.
19223 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19224 Adjust signatures to match updated version of code.
19225 (consing_since_gc): Now EMACS_INT, since a single hash table can
19226 use more than INT_MAX bytes.
19228 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19230 Make it possible to build with GCC-4.6+ -O2 -flto.
19232 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19234 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19236 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19237 Call minibuffer-inactive-mode.
19239 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19241 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19242 Update dependencies.
19244 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19246 * data.c (init_data): Remove code for UTS, this system is not
19249 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19251 Don't force ./temacs to start in terminal mode.
19253 * frame.c (make_initial_frame): Initialize faces in all cases, not
19254 only when CANNOT_DUMP is defined.
19255 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19257 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19259 * dispnew.c (add_window_display_history): Use const for the string
19260 pointer. Remove declaration, not needed.
19262 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19264 Use 'inline', not 'INLINE'.
19265 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19266 * alloc.c, fontset.c (INLINE): Remove.
19267 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19268 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19269 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19270 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19271 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19273 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19275 Make it possible to run ./temacs.
19277 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19278 syms_of_callproc does the same thing. Remove test for
19279 "initialized", do it in the caller.
19280 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19282 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19284 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19285 (read_minibuf): Use get_minibuffer.
19286 (syms_of_minibuf): Use DEFSYM.
19287 (Qmetadata): New var.
19288 * data.c (Qbuffer): Don't make it static.
19289 (syms_of_data): Use DEFSYM.
19291 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19293 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19294 (CCL_CODE_MIN): New macro.
19296 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19298 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19300 * eval.c (Qdebug): Now static.
19301 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19302 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19303 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19305 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19307 * image.c: Various fixes to ImageMagick code comments.
19308 (Fimagemagick_types): Doc fix.
19310 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19312 Minor fixes prompted by GCC 4.6.0 warnings.
19314 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19316 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19317 (x_clipboard_manager_save_all): Move extern decl to ...
19318 * xterm.h: ... here, so that it can be checked for consistency.
19320 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19322 * xselect.c (x_clipboard_manager_save_frame)
19323 (x_clipboard_manager_save_all): New functions.
19324 (Fx_clipboard_manager_save): Lisp function deleted.
19326 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19327 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19329 * xterm.h: Update prototype.
19331 2011-05-28 William Xu <william.xwl@gmail.com>
19333 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19334 exiting (Bug#8239).
19336 2011-05-28 Jim Meyering <meyering@redhat.com>
19338 Avoid a sign-extension bug in crypto_hash_function.
19339 * fns.c (to_uchar): Define.
19340 (crypto_hash_function): Use it to convert some newly-signed
19341 variables to unsigned, to avoid sign-extension bugs. For example,
19342 without this change, (md5 "truc") would evaluate to
19343 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19344 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19345 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19347 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19349 Integer overflow fixes.
19351 * dbusbind.c: Serial number integer overflow fixes.
19352 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19353 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19354 to hold a serial number that is too large for a fixnum.
19355 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19356 Check for serial numbers out of range. Decode any serial number
19357 that was so large that it became a float. (Bug#8722)
19359 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19360 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19361 Use XFASTINT rather than XUINT when numbers are nonnegative.
19362 (xd_append_arg, Fdbus_method_return_internal):
19363 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19364 arguments, check that Lisp number is nonnegative, rather than
19365 silently wrapping negative numbers around. (Bug#8722)
19366 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19369 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19371 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19373 ccl: Add integer overflow checks.
19374 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19375 (IN_INT_RANGE): New macros.
19376 (ccl_driver): Use them to check for integer overflow when
19377 decoding a CCL program. Many of the new checks are whether XINT (x)
19378 fits in int; it doesn't always, on 64-bit hosts. The new version
19379 doesn't catch all possible integer overflows, but it's an
19380 improvement. (Bug#8719)
19382 * alloc.c (make_event_array): Use XINT, not XUINT.
19383 There's no need for unsigned here.
19385 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19386 This follows up to the 2011-05-06 change that substituted uintptr_t
19387 for EMACS_INT. This case wasn't caught back then.
19389 Rework Fformat to avoid integer overflow issues.
19390 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19391 now (part of C89). Include <verify.h>.
19392 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19393 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19394 (Fformat): Avoid the prepass trying to compute sizes; it was only
19395 approximate and thus did not catch overflow reliably. Instead, walk
19396 through the format just once, formatting and computing sizes as we go,
19397 checking for integer overflow at every step, and allocating a larger
19398 buffer as needed. Keep track separately whether the format is
19399 multibyte. Keep only the most-recently calculated precision, rather
19400 than them all. Record whether each argument has been converted to
19401 string. Use EMACS_INT, not int, for byte and char and arg counts.
19402 Support field widths and precisions larger than INT_MAX. Avoid
19403 sprintf's undefined behavior with conversion specifications such as %#d
19404 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19405 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19406 formatting out-of-range floating point numbers with int
19407 formats. (Bug#8668)
19409 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19411 * data.c: Avoid integer truncation in expressions involving floats.
19412 * data.c: Include <intprops.h>.
19413 (arith_driver): When there's an integer overflow in an expression
19414 involving floating point, convert the integers to floating point
19415 so that the resulting value does not suffer from catastrophic
19416 integer truncation. For example, on a 64-bit host (* 4
19417 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19418 Do not rely on undefined behavior after integer overflow.
19420 merge count_size_as_multibyte, parse_str_to_multibyte
19421 * character.c, character.h (count_size_as_multibyte):
19422 Rename from parse_str_to_multibyte; all uses changed.
19423 Check for integer overflow.
19424 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19425 since it's now a duplicate of the other. This is more of
19426 a character than a buffer op, so better that it's in character.c.
19427 * fns.c, print.c: Adjust to above changes.
19429 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19431 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19433 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19435 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19436 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19437 (x_clipboard_manager_save): Now static.
19438 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19440 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19441 (crypto_hash_function): Now static.
19442 Fix pointer signedness problems. Avoid unnecessary initializations.
19444 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19446 * termhooks.h (Vselection_alist): Make it terminal-local.
19448 * terminal.c (create_terminal): Initialize it.
19450 * xselect.c: Support for clipboard managers.
19451 (Vselection_alist): Move to termhooks.h as terminal-local var.
19452 (LOCAL_SELECTION): New macro.
19453 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19454 (symbol_to_x_atom): Remove gratuitous arg.
19455 (x_handle_selection_request, lisp_data_to_selection_data)
19456 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19457 (x_own_selection, x_get_local_selection, x_convert_selection):
19458 New arg, specifying work frame. Use terminal-local Vselection_alist.
19459 (some_frame_on_display): Delete unused function.
19460 (Fx_own_selection_internal, Fx_get_selection_internal)
19461 (Fx_disown_selection_internal, Fx_selection_owner_p)
19462 (Fx_selection_exists_p): New optional frame arg.
19463 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19464 (x_handle_selection_clear): Don't treat other terminals with the
19465 same keyboard specially. Use the terminal-local Vselection_alist.
19466 (x_clear_frame_selections): Use Frun_hook_with_args.
19468 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19470 * xterm.h: Add support for those atoms.
19472 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19474 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19475 (converted_selections, conversion_fail_tag): New global variables.
19476 (x_selection_request_lisp_error): Free the above.
19477 (x_get_local_selection): Remove unnecessary code.
19478 (x_reply_selection_request): Args changed; handle arbitrary array
19479 of converted selections stored in converted_selections.
19480 Separate the XChangeProperty and SelectionNotify steps.
19481 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19482 (x_convert_selection): New function.
19483 (x_handle_selection_event): Simplify.
19484 (x_get_foreign_selection): Don't ignore incoming requests while
19485 waiting for an answer; this will fail when we implement
19486 SAVE_TARGETS, and seems unnecessary anyway.
19487 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19488 (Vx_sent_selection_functions): Doc fix.
19490 2011-05-26 Leo Liu <sdl.web@gmail.com>
19492 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19494 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19496 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19498 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19499 for fringe update if it has periodic bitmap.
19500 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19501 and fringe_bitmap_periodic_p.
19503 * fringe.c (get_fringe_bitmap_data): New function.
19504 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19505 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19506 row. Mark glyph row for fringe update if periodicity changed.
19508 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19509 for fringe update unless it has periodic bitmap.
19511 2011-05-25 Kenichi Handa <handa@m17n.org>
19513 * xdisp.c (get_next_display_element): Set correct it->face_id for
19514 a static composition.

19528 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19529 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19530 Remove macros that are defined and never used.
19531 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19533 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19535 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19536 (Fx_get_selection_internal): Minor cleanup.
19537 (Fx_own_selection_internal): Rename arguments for consistency with
19540 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19542 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19544 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19546 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19548 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19550 * dispnew.c (scrolling_window): Don't exclude the case that the
19551 last enabled row in the desired matrix touches the bottom boundary.
19553 2011-05-21 Glenn Morris <rgm@gnu.org>
19555 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19556 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19557 and add some more files.
19559 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19561 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19562 report_file_error introduced by the change from 2011-05-07.
19564 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19566 * systime.h (Time): Define only if emacs is defined.
19567 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19568 where the include path doesn't have X11/X.h by default. See
19569 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19571 2011-05-20 Kenichi Handa <handa@m17n.org>
19573 * composite.c (find_automatic_composition): Fix previous change.
19575 2011-05-20 Glenn Morris <rgm@gnu.org>
19577 * lisp.mk: New file, split from Makefile.in.
19578 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19579 (shortlisp): Remove.
19580 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19582 2011-05-19 Glenn Morris <rgm@gnu.org>
19584 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19585 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19586 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19587 (lisp): Set the order to that of loadup.el.
19588 (shortlisp): Make it a copy of $lisp.
19589 (SOME_MACHINE_LISP): Remove.
19590 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19591 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19593 2011-05-18 Kenichi Handa <handa@m17n.org>
19595 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19596 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19597 (find_automatic_composition): Mostly rewrite for efficiency.
19599 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19601 * makefile.w32-in: Update dependencies.
19603 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19605 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19606 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19608 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19610 Fix some integer overflow issues, such as string length overflow.
19612 * insdel.c (count_size_as_multibyte): Check for string overflow.
19614 * character.c (lisp_string_width): Check for string overflow.
19615 Use EMACS_INT, not int, for string indexes and lengths; in
19616 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19617 the resulting string length overflows an EMACS_INT; instead,
19618 report a string overflow if no precision given. When checking for
19619 precision exhaustion, use a check that cannot possibly have
19620 integer overflow. (Bug#8675)
19621 * character.h (lisp_string_width): Adjust to new signature.
19623 * alloc.c (string_overflow): New function.
19624 (Fmake_string): Use it. This doesn't change behavior, but saves
19625 a few bytes and will simplify future changes.
19626 * character.c (string_escape_byte8): Likewise.
19627 * lisp.h (string_overflow): New decl.
19629 Fixups, following up to the user-interface timestamp change.
19630 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19631 for UI timestamps, instead of unsigned long.
19632 * msdos.c (mouse_get_pos): Likewise.
19633 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19634 * w32gui.h (Time): Define by including "systime.h" rather than by
19635 declaring it ourselves. (Bug#8664)
19637 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19638 * image.c (clear_image_cache): Likewise.
19640 * term.c (term_mouse_position): Don't assume time_t wraparound.
19642 Be more systematic about user-interface timestamps.
19643 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19644 and sometimes 'EMACS_UINT', to represent these timestamps.
19645 This change causes it to use 'Time' uniformly, as that's what X uses.
19646 This makes the code easier to follow, and makes it easier to catch
19647 integer overflow bugs such as Bug#8664.
19648 * frame.c (Fmouse_position, Fmouse_pixel_position):
19649 Use Time, not unsigned long, for user-interface timestamps.
19650 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19651 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19652 * keyboard.h (last_event_timestamp): Likewise.
19653 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19654 * menu.h (xmenu_show): Likewise.
19655 * term.c (term_mouse_position): Likewise.
19656 * termhooks.h (struct input_event.timestamp): Likewise.
19657 (struct terminal.mouse_position_hook): Likewise.
19658 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19659 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19660 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19661 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19662 what it was before.
19663 * menu.h, termhooks.h: Include "systime.h", for Time.
19665 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19666 Don't assume that the difference between two unsigned long values
19667 can fit into an integer. At this point, we know button_down_time
19668 <= event->timestamp, so the difference must be nonnegative, so
19669 there's no need to cast the result if double-click-time is
19670 nonnegative, as it should be; check that it's nonnegative, just in
19671 case. This bug is triggered when events are more than 2**31 ms
19672 apart (about 25 days). (Bug#8664)
19674 * xselect.c (last_event_timestamp): Remove duplicate decl.
19675 (x_own_selection): Remove needless cast to unsigned long.
19677 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19678 that always fit in int. Use a sentinel instead of a counter, to
19679 avoid a temp and to allay GCC's concerns about possible int overflow.
19680 * frame.h (struct frame): Use int for menu_bar_items_used
19681 instead of EMACS_INT, since it always fits in int.
19683 * menu.c (grow_menu_items): Check for int overflow.
19685 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19687 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19688 Before, the code was not consistent. These values cannot exceed
19689 2**31 - 1 so there's no need to make them unsigned.
19690 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19691 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19692 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19694 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19696 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19697 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19698 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19699 presumably because the widths might not match.
19701 * window.c (size_window): Avoid needless test at loop start.
19703 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19705 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19707 2011-05-12 Drew Adams <drew.adams@oracle.com>
19709 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19711 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19713 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19714 `width' to `bar_area_x' and `bar_area_width', respectively.
19715 (x_scroll_run): Take account of fringe background extension.
19717 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19718 Rename local vars `left' and `width' to `bar_area_x' and
19719 `bar_area_width', respectively.
19720 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19721 background extension.
19723 2011-05-10 Jim Meyering <meyering@redhat.com>
19725 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19727 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19729 * image.c (Finit_image_library): Return t for built-in image types,
19730 like pbm and xbm. (Bug#8640)
19732 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19734 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19736 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19738 * w32console.c (Fset_screen_color): Doc fix.
19739 (Fget_screen_color): New function.
19740 (syms_of_ntterm): Defsubr it.
19742 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19743 unlink the temporary file if Fcall_process didn't create it in the
19745 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19746 child process will be redirected to a file specified with `:file'.
19747 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19748 cue to call_process_cleanup not to close that handle.
19750 2011-05-07 Ben Key <bkey76@gmail.com>
19752 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19753 one of two shell specific rules, either bootstrap-temacs-CMD or
19754 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19755 to the previous implementation of the bootstrap-temacs rule.
19756 The bootstrap-temacs-CMD rule is similar to the previous
19757 implementation of the bootstrap-temacs rule except that it
19758 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19761 These changes, along with some changes to nt/configure.bat,
19762 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19763 earlier fix to add support for --cflags and --ldflags options
19764 that include quotes so that it works whether make uses cmd or
19767 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19769 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19770 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19772 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19773 a string. Handle both cases.
19774 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19775 (Fdbus_register_method): Use Qinvalid_function.
19777 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19779 * makefile.w32-in: Update dependencies.
19780 (LISP_H): Add inttypes.h and stdin.h.
19781 (PROCESS_H): Add unistd.h.
19783 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19785 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19786 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19788 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19790 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19792 * term.c (vfatal): Remove stray call to va_end.
19793 It's not needed and the C Standard doesn't allow it here anyway.
19795 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19796 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19798 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19801 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19803 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19805 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19807 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19809 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19811 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19812 * charset.c (Fdefine_charset_internal): Don't initialize
19813 charset.code_space[15]. The value was garbage, on hosts with
19814 32-bit int (Bug#8600).
19816 * lread.c (read_integer): Be more consistent with string-to-number.
19817 Use string_to_number to do the actual conversion; this avoids
19818 rounding errors and fixes some other screwups. Without this fix,
19819 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19820 (digit_to_number): Move earlier, for benefit of read_integer.
19821 Return -1 if the digit is out of range for the base, -2 if it is
19822 not a digit in any supported base. (Bug#8602)
19824 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19826 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19827 to match comment at start of function. This also removes a
19828 GCC warning about overflow in a 32+64-bit port.
19830 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19832 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19833 Reported by Stefan Monnier in
19834 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19835 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19836 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19838 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19839 (EMACS_UINTPTR): Likewise, with uintptr_t.
19841 * lisp.h: Prefer 64-bit EMACS_INT if available.
19842 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19843 on 32-bit hosts that have 64-bit int, so that they can access
19845 However, temporarily disable this change unless the temporary
19846 symbol WIDE_EMACS_INT is defined.
19848 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19850 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19851 This removes an assumption that EMACS_INT and long are the same
19852 width as pointers. The assumption is true for Emacs porting targets
19853 now, but we want to make other targets possible.
19854 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19855 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19856 In the rest of the code, change types of integers that hold casted
19857 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19858 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19859 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19860 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19861 No need to cast type when ORing.
19862 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19863 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19864 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19865 assume EMACS_INT is the same width as char *.
19866 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19867 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19868 Remove no-longer-needed casts.
19869 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19870 (xg_tool_bar_help_callback, xg_make_tool_item):
19871 Use EMACS_INTPTR to hold an integer
19872 that will be cast to void *; this can avoid a GCC warning
19873 if EMACS_INT is not the same width as void *.
19874 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19875 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19876 (current_message_1, set_message_1):
19877 Use a local to convert to proper width without a cast.
19878 * xmenu.c (dialog_selection_callback): Likewise.
19880 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19881 Also, don't assume VALBITS / RAND_BITS is less than 5,
19882 and don't rely on undefined behavior when shifting a 1 left into
19884 * lisp.h (get_random): Change signature to match.
19886 * lread.c (hash_string): Use size_t, not int, for hash computation.
19887 Normally we prefer signed values; but hashing is special, because
19888 it's better to use unsigned division on hash table sizes so that
19889 the remainder is nonnegative. Also, size_t is the natural width
19890 for hashing into memory. The previous code used 'int', which doesn't
19891 retain enough info to hash well into very large tables.
19892 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19894 * dbusbind.c: Don't possibly lose pointer info when converting.
19895 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19896 Use XPNTR rather than XHASH, so that the high-order bits of
19897 the pointer aren't lost when converting through void *.
19899 * eval.c (Fautoload): Don't double-shift a pointer.
19901 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19903 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19905 * gnutls.c (DEF_GNUTLS_FN):
19906 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19908 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19910 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19913 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19915 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19916 New version that can reserve upto 2GB of heap space.
19918 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19920 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19922 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19924 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19925 `gnutls_certificate_set_x509_key_file'.
19927 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19929 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19930 Update dependencies.
19932 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19934 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19935 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19936 Remove unused parameter `fildes'.
19937 * process.c (read_process_output, send_process): Don't pass it.
19939 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19941 Fix previous change: the library cache is defined in w32.c.
19942 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19943 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19945 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19947 Implement dynamic loading of GnuTLS on Windows.
19949 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19950 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19951 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19954 * gnutls.c (Qgnutls_dll): Define.
19955 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19956 (gnutls_*): Declare function pointers.
19957 (init_gnutls_functions): New function to initialize function pointers.
19958 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19959 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19960 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19961 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19962 (emacs_gnutls_write, emacs_gnutls_read)
19963 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19964 (Fgnutls_available_p): New function.

19982 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19984 * process.c: Include lisp.h before w32.h, not after.
19985 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19986 instead of gnutls_record_check_pending.

19990 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19992 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

20038 rather than `XVECTOR (FOO)->size'.
20040 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20041 inttypes.h, as a gnulib replacement is used if it not available in

20063 %llo or %llx format is passed. (Bug#8545)
20065 * window.c (window_scroll_line_based): Use a marker instead of
20066 simple variables to record original value of point. (Bug#7952)

20069 produced by %s or %c overflows available buffer space. (Bug#8545)
20071 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20073 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20076 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20078 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20080 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20082 * keyboard.c (Qdelayed_warnings_hook): Define.
20083 (command_loop_1): Run `delayed-warnings-hook'
20084 if Vdelayed_warnings_list is non-nil.
20085 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20086 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20088 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20090 * doprnt.c (doprnt): Don't return value smaller than the buffer
20091 size if the message was truncated. (Bug#8545).
20093 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20095 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

20098 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20100 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20102 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20104 * makefile.w32-in: Update dependencies.
20106 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20108 Improve `doprnt' and its usage. (Bug#8545)
20109 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20110 `format_end'. Remove support for %l as a conversion specifier.
20111 Don't use xrealloc. Improve diagnostics when the %l size modifier
20112 is used. Update the commentary.
20114 * eval.c (verror): Simplify calculation of size_t.
20116 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20119 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20121 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20124 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20126 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20127 This makes this file independent of the recent pseudovector change.
20129 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20131 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20133 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20134 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20135 Remove unused local.
20136 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20138 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20139 GCC 4.6.0 optimizes based on type-based alias analysis.
20140 For example, if b is of type struct buffer * and v of type struct
20141 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20142 != &v->size, and therefore "v->size = 1; b->size = 2; return
20143 v->size;" must therefore return 1. This assumption is incorrect
20144 for Emacs, since it type-puns struct Lisp_Vector * with many other
20145 types. To fix this problem, this patch adds a new type struct
20146 vectorlike_header that documents the constraints on layout of vectors
20147 and pseudovectors, and helps optimizing compilers not get fooled
20148 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20149 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20150 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20152 (XSETPVECTYPE): Rewrite in terms of new macro.
20153 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20154 This is a bit clearer, and further avoids the possibility of
20155 undesirable aliasing.
20156 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20157 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20158 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20159 since Lisp_Subr is a special case (no "next" field).
20160 (ASIZE): Now uses header.size rather than size.
20161 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20162 to avoid the hassle of writing XVECTOR (foo)->header.size.
20163 (struct vectorlike_header): New type.
20164 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20165 object, to help avoid aliasing.
20166 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20167 (SUBRP): Likewise, since Lisp_Subr is a special case.
20168 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20169 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20170 (struct Lisp_Hash_Table): Combine first two members into a single
20171 struct vectorlike_header member. All uses of "size" and "next" members
20172 changed to be "header.size" and "header.next".
20173 * buffer.h (struct buffer): Likewise.
20174 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20175 * frame.h (struct frame): Likewise.
20176 * process.h (struct Lisp_Process): Likewise.
20177 * termhooks.h (struct terminal): Likewise.
20178 * window.c (struct save_window_data, struct saved_window): Likewise.
20179 * window.h (struct window): Likewise.
20180 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20181 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20182 * buffer.c (init_buffer_once): Likewise.
20183 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20185 * process.c (Fformat_network_address): Use local var for size,
20188 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20190 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20191 * data.c (atof): Remove decl; no longer used or needed.
20192 (digit_to_number): Move to lread.c.
20193 (Fstring_to_number): Use new string_to_number function, to be
20194 consistent with how the Lisp reader treats infinities and NaNs.
20195 Do not assume that floating-point numbers represent EMACS_INT
20196 without losing information; this is not true on most 64-bit hosts.
20197 Avoid double-rounding errors, by insisting on integers when
20198 parsing non-base-10 numbers, as the documentation specifies.
20199 * lisp.h (string_to_number): New decl, replacing ...
20200 (isfloat_string): Remove.
20201 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20202 (read1): Do not accept +. and -. as integers; this
20203 appears to have been a coding error. Similarly, do not accept
20204 strings like +-1e0 as floating point numbers. Do not report
20205 overflow for integer overflows unless the base is not 10 which
20206 means we have no simple and reliable way to continue.
20207 Break out the floating-point parsing into a new
20208 function string_to_number, so that Fstring_to_number parses
20209 floating point numbers consistently with the Lisp reader.
20210 (digit_to_number): Move here from data.c. Make it static inline.
20211 (E_CHAR, EXP_INT): Remove, replacing with ...
20212 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20213 (string_to_number): New function, replacing isfloat_string.
20214 This function checks for valid syntax and produces the resulting
20215 Lisp float number too. Rework it so that string-to-number
20216 no longer mishandles examples like "1.0e+". Use strtoumax,
20217 so that overflow for non-base-10 numbers is reported only when
20218 there's no portable and simple way to convert to floating point.
20220 * textprop.c (set_text_properties_1): Rewrite for clarity,
20221 and to avoid GCC warning about integer overflow.
20223 * intervals.h (struct interval): Use EMACS_INT for members
20224 where EMACS_UINT might cause problems. See
20225 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20226 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20227 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20229 (offset_intervals): Tell GCC not to worry about length overflow
20230 when negating a negative length.
20232 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20233 (overrun_check_free): Likewise.
20235 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20236 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20239 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20240 (gnutls_make_error): Rename local to avoid shadowing.
20241 (gnutls_emacs_global_deinit): ifdef out; not used.
20242 (Fgnutls_boot): Use const for pointer to readonly storage.
20243 Comment out unused local. Fix pointer signedness problems.
20245 * lread.c (openp): Don't stuff size_t into an 'int'.
20246 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20247 about possible signed overflow.
20249 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20250 (GDK_KEY_g): Don't define if already defined.
20251 (xg_prepare_tooltip): Avoid pointer signedness problem.
20252 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20254 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20255 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20257 * xfns.c (Fx_window_property): Simplify a bit,
20258 to make a bit faster and to avoid GCC 4.6.0 warning.
20259 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20261 * fns.c (internal_equal): Don't assume size_t fits in int.
20263 * alloc.c (compact_small_strings): Tighten assertion a little.
20265 Replace pEd with more-general pI, and fix some printf arg casts.
20266 * lisp.h (pI): New macro, generalizing old pEd macro to other
20267 conversion specifiers. For example, use "...%"pI"d..." rather
20268 than "...%"pEd"...".
20269 (pEd): Remove. All uses replaced with similar uses of pI.
20270 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20271 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20272 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20273 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20274 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20275 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20276 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20278 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20279 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20280 * print.c (safe_debug_print, print_object): Likewise.
20281 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20283 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20284 avoiding the 0 flag, which is not portable.
20285 * process.c (Fmake_network_process): Use pI to avoid cast.
20286 * region-cache.c (pp_cache): Likewise.
20287 * xdisp.c (decode_mode_spec): Likewise.
20288 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20289 behavior on 64-bit hosts with printf arg.
20290 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20291 (x_stop_queuing_selection_requests): Likewise.
20292 (x_get_window_property): Don't truncate byte count to an 'int'
20295 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20296 here, since it parses constructs like leading '-' and spaces,
20297 which are not wanted; and it overflows with large numbers.
20298 Instead, simply match F[0-9]+, which is what is wanted anyway.
20300 * alloc.c: Remove unportable assumptions about struct layout.
20301 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20302 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20303 (allocate_vectorlike, make_pure_vector): Use the new macros,
20304 plus offsetof, to remove unportable assumptions about struct layout.
20305 These assumptions hold on all porting targets that I know of, but
20306 they are not guaranteed, they're easy to remove, and removing them
20307 makes further changes easier.
20309 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20310 This doesn't fix a bug but makes the code clearer.
20311 (string_overrun_cookie): Now const. Use initializers that
20312 don't formally overflow signed char, to avoid warnings.
20313 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20314 can cause Emacs to crash when string overrun checking is enabled.
20315 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20316 multiple of sizeof (EMACS_INT); it need not be, if
20317 alignof(EMACS_INT) < sizeof (EMACS_INT).
20318 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20320 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20324 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20326 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20327 supposed to be handshaking. (Bug#8556)
20328 Reported by Paul Eggert <eggert@cs.ucla.edu>.

20332 * lisp.h (Qdebug): List symbol.
20333 * eval.c (Qdebug): Restore global linkage.
20334 * keyboard.c (debug-on-event): New variable.
20335 (handle_user_signal): Break into debugger when debug-on-event
20336 matches the current signal symbol.
20338 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20340 * alloc.c (check_sblock, check_string_bytes)
20341 (check_string_free_list): Convert to standard C.
20343 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20345 * w32.c (emacs_gnutls_push): Fix typo.
20347 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20349 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20350 "cast to pointer from integer of different size".
20352 Improve doprnt and its use in verror. (Bug#8545)
20353 * doprnt.c (doprnt): Document the set of format control sequences
20354 supported by the function. Use SAFE_ALLOCA instead of always
20357 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20358 is one byte too soon. Don't use xrealloc; instead xfree and
20361 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20363 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20366 * gnutls.c: Renamed global_initialized to
20367 gnutls_global_initialized. Added internals for the
20368 :verify-hostname-error, :verify-error, and :verify-flags
20369 parameters of `gnutls-boot' and documented those parameters in the
20370 docstring. Start callback support.
20371 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20372 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20373 on error. Return error code.
20374 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20375 (emacs_gnutls_read): Likewise.
20376 (Fgnutls_boot): Return handshake error code.
20377 (emacs_gnutls_handle_error): New function.
20378 (wsaerror_to_errno): Likewise.

20383 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
20384 (emacs_gnutls_push): Likewise.
20386 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
20388 * process.c (wait_reading_process_output): Check if GnuTLS
20389 buffered some data internally if no FDs are set for TLS

20895 * font.c (font_close_object): Now static.
20896 * font.h (font_close_object): Remove.
20897 * fontset.c (FONTSET_OBJLIST): Remove.

20900 * fontset.h (face_suitable_for_char_p): Remove decl.
20901 * xfaces.c (face_at_string_position):
20902 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
20903 since 0 is always ASCII.
20905 * fns.c (weak_hash_tables): Now static.
20907 * fileio.c: Make symbols static if they're not exported.

20926 * editfns.c, lisp.h (get_operating_system_release): Remove.
20927 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20928 worth the hassle of breaking this out.
20930 * xterm.c: Make symbols static if they're not exported.
20931 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
20932 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

21034 * buffer.c (buffer_count): Remove unused var.

21043 * atimer.h (run_all_atimers): Remove; not exported.
21045 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21046 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21047 was inaccessible from Lisp.
21048 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21049 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21051 alloc.c: Import and export fewer symbols, and remove unused items.
21052 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21054 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21055 it's not optimized away by whole-program optimization.

21057 (catchlist, handlerlist, mark_backtrace):
21058 Declare only if BYTE_MARK_STACK.

21067 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21068 (mark_backtrace): Define only if BYTE_MARK_STACK.
21069 * xdisp.c (message_enable_multibyte): Now static.
21071 Declare Lisp_Object Q* variables to be 'static' if not exported.
21072 This makes it easier for human readers (and static analyzers)
21073 to see whether these variables are used from other modules.
21074 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21075 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

21084 Remove decls of unexported vars.
21085 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21087 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21089 Make Emacs functions such as Fatom 'static' by default.
21090 This makes it easier for human readers (and static analyzers)
21091 to see whether these functions can be called from other modules.
21092 DEFUN now defines a static function. To make the function external
21093 so that it can be used in other C modules, use the new macro DEFUE.
21094 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21095 (Finit_image_library):
21096 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21097 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21098 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21099 Remove decls, since these functions are now static.
21100 (Funintern, Fget_internal_run_time): New decls, since these functions
21101 were already external.
21103 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21104 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21110 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21111 Mark functions with DEFUE instead of DEFUN,
21112 if they are used in other modules.
21113 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21114 decls for now-static functions.
21115 * buffer.h (Fdelete_overlay): Remove decl.
21116 * callproc.c (Fgetenv_internal): Mark as internal.
21117 * composite.c (Fremove_list_of_text_properties): Remove decl.

21125 * image.c (Finit_image_library): New forward static decl.
21126 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21127 * intervals.h (Fprevious_property_change):
21128 (Fremove_list_of_text_properties): Remove decls.
21129 * keyboard.c (Fthis_command_keys): Remove decl.
21130 (Fcommand_execute): New forward static decl.

21146 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21148 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21151 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21153 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21154 when at ZV. (Bug#8487)
21156 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21158 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21160 * keyboard.c (parse_tool_bar_item): Likewise.
21161 * sound.c (sound_cleanup, alsa_close): Likewise.
21162 * termcap.c (tgetent): Likewise.
21163 * xfns.c (x_default_font_parameter): Likewise.
21164 * xsettings.c (read_and_apply_settings): Likewise.
21166 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21167 (overrun_check_free): Protoize.
21169 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21171 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21172 since callers should never pass a negative size.
21173 Change the signature to match that of plain 'read' and 'write'; see
21174 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21175 * lisp.h: Update prototypes of emacs_write and emacs_read.
21177 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21179 * xdisp.c (redisplay_window): Don't try to determine the character
21180 position of the scroll margin if the window start point w->startp
21181 is outside the buffer's accessible region. (Bug#8468)
21183 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21185 Fix write-region and its subroutines for buffers > 2GB.
21186 * fileio.c (a_write, e_write): Modify declaration of arguments and
21187 local variables to support buffers larger than 2GB.
21188 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21190 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21191 argument, local variables, and return value.
21193 * lisp.h: Update prototypes of emacs_write and emacs_read.
21195 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21197 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21199 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21201 Fix more problems found by GCC 4.6.0's static checks.
21203 * xdisp.c (vmessage): Use a better test for character truncation.
21205 * charset.c (load_charset_map): <, not <=, for optimization,
21206 and to avoid potential problems with integer overflow.
21207 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21208 * casetab.c (set_identity, shuffle): Likewise.
21209 * editfns.c (Fformat): Likewise.
21210 * syntax.c (skip_chars): Likewise.
21212 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21213 This also lets GCC 4.6.0 generate slightly better loop code.
21215 * callint.c (Fcall_interactively): <, not <=, for optimization.
21216 (Fcall_interactively): Count the number of arguments produced,
21217 not the number of arguments given. This is simpler and lets GCC
21218 4.6.0 generate slightly better code.
21220 * ftfont.c: Distingish more carefully between FcChar8 and char.
21221 The previous code passed unsigned char * to a functions like
21222 strlen and xstrcasecmp that expect char *, which does not
21223 conform to the C standard.
21224 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21225 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21226 char * when the C standard requires it.
21228 * keyboard.c (read_char): Remove unused var.
21230 * eval.c: Port to Windows vsnprintf (Bug#8435).
21231 Include <limits.h>.
21232 (SIZE_MAX): Define if the headers do not.
21233 (verror): Do not give up if vsnprintf returns a negative count.
21234 Instead, grow the buffer. This ports to Windows vsnprintf, which
21235 does not conform to C99. Problem reported by Eli Zaretskii.
21236 Also, simplify the allocation scheme, by avoiding the need for
21237 calling realloc, and removing the ALLOCATED variable.
21239 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21241 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21242 But keep the doprint source code for now, as we might revamp it
21243 and use it again (Bug#8435).
21244 * lisp.h (doprnt): Remove.
21245 * Makefile.in (base_obj): Remove doprnt.o.
21246 * deps.mk (doprnt.o): Remove.
21248 error: Print 32- and 64-bit integers portably (Bug#8435).
21249 Without this change, on typical 64-bit hosts error ("...%d...", N)
21250 was used to print both 32- and 64-bit integers N, which relied on
21251 undefined behavior.
21252 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21253 * lisp.h (error, verror): Mark as printf-like functions.
21254 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21255 Report overflow in size calculations when allocating printf buffer.
21256 Do not truncate output string at its first null byte.
21257 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21258 Truncate the output at a character boundary, since vsnprintf does not
21260 * charset.c (check_iso_charset_parameter): Convert internal
21261 character to string before calling 'error', since %c now has the
21263 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21264 overflow when computing char to be passed to 'error'. Do not
21265 pass Lisp_Object to 'error'; pass the integer instead.
21266 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21267 formatted with plain %d.
21269 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21271 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21273 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

21283 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21284 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21285 return ssize_t not "int", and use size_t as the buffer length.
21286 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21287 * gnutls.h: Update declarations.
21288 * process.c (read_process_output): Use ssize_t, to match.
21289 (send_process): Likewise.
21291 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21293 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21295 2011-04-09 Chong Yidong <cyd@stupidchicken.com>

21298 Use unsigned char, to match FcChar8 type definition.
21300 * xterm.c (handle_one_xevent):
21301 * xmenu.c (create_and_show_popup_menu):
21302 * xselect.c (x_decline_selection_request)
21303 (x_reply_selection_request): Avoid type-punned deref of X events.
21305 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21307 Fix some uses of `int' instead of EMACS_INT.
21308 * search.c (string_match_1, fast_string_match)
21309 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21310 (scan_buffer, find_next_newline_no_quit)

21404 This avoids several warnings with gcc -Wstrict-overflow.
21405 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21406 directly, rather than having caller test rule sign. This avoids
21407 some unnecessary tests.
21408 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21409 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21410 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21412 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21413 (xfont_open): Avoid unnecessary tests.
21415 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21417 * composite.h, composite.c (composition_gstring_put_cache):
21418 Use EMACS_INT, not int, for length.
21420 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21421 breaking out part of COMPOSITION_DECODE_RULE.
21422 (COMPOSITION_DECODE_RULE): Use it.
21423 * composite.c (get_composition_id): Remove unused local vars,
21424 by using the new macro.
21426 * textprop.c (set_text_properties_1): Change while to do-while,
21427 since the condition is always true at first.
21429 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21430 (interval_deletion_adjustment): Return unsigned value.
21433 * process.c (list_processes_1, create_pty, read_process_output):

21449 * print.c (print_error_message): Avoid int overflow.
21451 * font.c (font_list_entities): Redo for clarity,
21452 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21454 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21455 (font_score): Avoid potential overflow in diff calculation.
21457 * fns.c (substring_both): Remove var that is set but not used.
21458 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21460 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21462 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21463 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21464 can always succeed if overflow has undefined behavior.
21466 * search.c (boyer_moore, wordify): Remove vars set but not used.
21467 (wordify): Omit three unnecessary tests.
21469 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21478 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21479 (Finsert_file_contents): Remove unnecessary code checking fd.
21481 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21482 Check for integer overflow on size calculations.
21484 * buffer.c (Fprevious_overlay_change): Remove var that is set
21487 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21488 Remove vars that are set but not used.
21489 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21490 (timer_check_2): Mark vars as initialized.
21492 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21494 * image.c (lookup_image): Remove var that is set but not used.
21495 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21497 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21498 that are set but not used.
21500 * xfns.c (make_invisible_cursor): Don't return garbage
21501 if XCreateBitmapFromData fails (Bug#8410).
21503 * xselect.c (x_get_local_selection, x_handle_property_notify):
21504 Remove vars that are set but not used.
21506 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21507 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21509 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21510 Remove var that is set but not used.
21511 (scroll_bar_windows_size): Now size_t, not int.
21512 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21513 Check for overflow.
21515 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21516 (map_tty_color) [!defined MSDOS]: Likewise.
21518 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21520 * coding.c: Remove vars that are set but not used.
21521 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21522 All callers changed.
21523 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21524 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21525 (decode_coding_charset): Remove vars that are set but not used.
21527 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21528 that is set but not used.
21530 * print.c (print_object): Remove var that is set but not used.
21532 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21533 The gnulib version avoids calling malloc in the usual case,
21534 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21535 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21536 * filelock.c (current_lock_owner): Likewise.
21537 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21538 * sysdep.c: Include allocator.h, careadlinkat.h.
21539 (emacs_no_realloc_allocator): New static constant.
21540 (emacs_readlink): New function.
21541 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21542 ../lib/careadlinkat.h.
21544 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21546 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21547 first non-nil return value).

21551 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21552 if not defined (Bug#8403).

21561 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21562 and thereabouts. All callers changed.
21563 (get_per_char_metric): Remove parameter `f', unused since
21564 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21566 2011-04-02 Jim Meyering <meyering@redhat.com>
21568 do not dereference NULL upon failed strdup
21569 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21570 (ns_get_family): Likewise.
21572 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21574 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21576 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21578 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21581 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21583 Add lexical binding.
21585 * window.c (Ftemp_output_buffer_show): New fun.
21586 (Fsave_window_excursion):
21587 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21589 * lread.c (lisp_file_lexically_bound_p): New function.
21590 (Fload): Bind Qlexical_binding.
21591 (readevalloop): Remove `evalfun' arg.
21592 Bind Qinternal_interpreter_environment.
21593 (Feval_buffer): Bind Qlexical_binding.
21594 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21596 (syms_of_lread): Declare `lexical-binding'.
21598 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21600 * keyboard.c (eval_dyn): New fun.
21601 (menu_item_eval_property): Use it.
21603 * image.c (parse_image_spec): Use Ffunctionp.
21605 * fns.c (concat, mapcar1): Accept byte-code-functions.
21607 * eval.c (Fsetq): Handle lexical vars.
21608 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21609 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21610 (FletX, Flet): Obey lexical binding.
21611 (Fcommandp): Handle closures.
21612 (Feval): New `lexical' arg.
21613 (eval_sub): New function extracted from Feval. Use it almost
21614 everywhere where Feval was used. Look up vars in lexical env.
21616 (Ffunctionp): Move from subr.el.
21617 (Ffuncall): Handle closures.
21618 (apply_lambda): Remove `eval_flags'.
21619 (funcall_lambda): Handle closures and new byte-code-functions.
21620 (Fspecial_variable_p): New function.
21621 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21622 but without exporting it to Lisp.
21624 * doc.c (Fdocumentation, store_function_docstring):
21625 * data.c (Finteractive_form): Handle closures.
21627 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21630 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21632 (exec_byte_code): New function extracted from Fbyte_code to handle new
21633 calling convention for byte-code-functions. Add new byte-codes.
21635 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

21645 * xdisp.c (SCROLL_LIMIT): New macro.
21646 (try_scrolling): Use it when setting scroll_limit.
21647 Limit scrolling to 100 screen lines.
21648 (redisplay_window): Even when falling back on "recentering",
21649 position point in the window according to scroll-conservatively,
21650 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21652 (try_scrolling): When point is above the window, allow searching
21653 as far as scroll_max, or one screenful, to compute vertical
21654 distance from PT to the scroll margin position. This prevents
21655 try_scrolling from unnecessarily failing when
21656 scroll-conservatively is set to a value slightly larger than the
21657 window height. Clean up the case of PT below the margin at bottom
21658 of window: scroll_max can no longer be INT_MAX. When aggressive
21659 scrolling is in use, don't let point enter the opposite scroll
21660 margin as result of the scroll.
21661 (syms_of_xdisp) <scroll-conservatively>: Document the
21662 threshold of 100 lines for never-recentering scrolling.

21669 (message_log_check_duplicate): Remove parameters `prev_bol' and
21670 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21671 (redisplay_internal): Remove parameter `preserve_echo_area',
21672 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21674 * indent.c (Fvertical_motion):
21675 * window.c (window_scroll_pixel_based, Frecenter):
21676 Don't pass `need_y_p' to `move_it_by_lines'.
21678 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21680 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21681 steal a few bits to be more compact.
21682 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21683 Remove unneeded casts.
21685 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21687 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21689 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21690 binding" message (bug#7967).
21692 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21694 Fix more problems found by GCC 4.6.0's static checks.
21696 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21697 Remove unused local var.
21699 * editfns.c (Fmessage_box): Remove unused local var.
21701 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21702 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21703 Omit unused local vars.
21704 * window.c (shrink_windows): Omit unused local var.
21705 * menu.c (digest_single_submenu): Omit unused local var.
21706 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21707 Omit unused local var.
21709 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21710 Don't assume string length fits in int.
21711 (keyremap_step, read_key_sequence): Use size_t for sizes.
21712 (read_key_sequence): Don't check last_real_key_start redundantly.
21714 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21715 instead of alloca (Bug#8344).
21717 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21718 (Fbacktrace_frame): Don't assume nframes fits in int.
21720 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21722 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21725 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21727 * cm.c (calccost): Turn while-do into do-while, for clarity.
21729 * keyboard.c (syms_of_keyboard): Use the same style as later
21730 in this function when indexing through an array. This also
21731 works around GCC bug 48267.
21733 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21735 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21737 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21738 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21740 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21741 This avoids undefined behavior on integer overflow, and is a bit
21742 more convenient anyway since it is compared to a size_t variable.
21744 Variadic C functions now count arguments with size_t, not int.
21745 This avoids an unnecessary limitation on 64-bit machines, which
21746 caused (substring ...) to crash on large vectors (Bug#8344).
21747 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21748 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21755 (funcall_lambda, mark_backtrace): Likewise.
21756 * fns.c (concat): Likewise.
21757 * frame.c (x_set_frame_parameters): Likewise.
21758 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21759 0 if not found, not -1. All callers changed.
21761 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21762 (stack_copy_size): Now size_t, not int.
21763 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21784 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21785 don't set the hook to nil, but remove the offending function instead.
21786 (Qcommand_hook_internal): Remove, unused.
21787 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21788 Vcommand_hook_internal.

21968 * buffer.c (Fkill_all_local_variables):
21969 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21971 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21972 unconditionally since it does the check itself.
21974 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21976 Fix more problems found by GCC 4.5.2's static checks.
21978 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21979 the first time through the loop, since we know p0 < p1 then.
21980 This also avoids a gcc -Wstrict-overflow warning.
21982 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21983 leading to a memory leak, possible in functions like
21984 load_charset_map_from_file that can allocate an unbounded number
21985 of objects (Bug#8318).
21987 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21988 that could (at least in theory) be that large.
21990 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21991 This is less likely to overflow, and avoids undefined behavior if
21992 overflow does occur. All callers changed. Use strtoul to scan
21993 for the unsigned long integer.
21994 (pint2hrstr): Simplify and tune code slightly.
21995 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22010 * process.c (Fmake_network_process): Use socklen_t, not int,
22011 where POSIX says socklen_t is required in portable programs.
22012 This fixes a porting bug on hosts like 64-bit HP-UX, where
22013 socklen_t is wider than int (Bug#8277).
22014 (Fmake_network_process, server_accept_connection):
22015 (wait_reading_process_output, read_process_output):
22018 * process.c: Rename or move locals to avoid shadowing.

22028 Make tparam.h and terminfo.c consistent.
22029 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22030 Include tparam.h instead, since it declares them.
22031 * cm.h (PC): Remove extern decl; tparam.h now does this.
22032 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22033 * terminfo.c: Include tparam.h, to check interfaces.
22034 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22035 (tparam): Adjust signature to match interface in tparam.h;
22036 this removes some undefined behavior. Check that outstring and len
22037 are zero, which they always are with Emacs.
22038 * tparam.h (PC, BC, UP): New extern decls.
22040 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22041 (xftfont_open): Rename locals to avoid shadowing.

22055 * composite.c (composition_compute_stop_pos): Rename local to
22057 (composition_reseat_it): Remove unused locals.
22058 (find_automatic_composition, composition_adjust_point): Likewise.
22059 (composition_update_it): Mark var as initialized.
22060 (find_automatic_composition): Mark vars as initialized,
22061 with a FIXME (Bug#8290).
22063 character.h: Rename locals to avoid shadowing.
22064 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22065 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22066 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22067 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22068 to avoid shadowing.
22070 * textprop.c (property_change_between_p): Remove; unused.
22072 * intervals.c (interval_start_pos): Now static.
22074 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22080 Fix pointer signedness.
22081 (alsa_choose_format): Remove unused local var.
22082 (wav_play): Initialize a variable to 0, to prevent undefined
22083 behavior (Bug#8278).
22085 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22087 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22089 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22090 clobbering (Bug#8298).
22091 * sysdep.c (sys_subshell): Likewise.
22092 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22094 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22095 This should get cleaned up, so that child_setup has the
22096 same signature on all platforms.
22098 * callproc.c (call_process_cleanup): Now static.
22099 (relocate_fd): Rename locals to avoid shadowing.
22101 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22103 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22104 not to be necessary, and produces flickering.
22106 2011-03-20 Glenn Morris <rgm@gnu.org>
22108 * config.in: Remove file.
22110 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22140 (sigchld_handler): Now static.
22142 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22143 That way, the code declares only the vars that it needs.

22152 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22153 (CONSTANTLIM): Remove; unused.
22154 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22155 Define only if needed.
22157 * unexelf.c (unexec): Name an expression,
22158 to avoid gcc -Wbad-function-cast warning.
22159 Use a different way to cause a compilation error if anyone uses
22160 n rather than nn, a way that does not involve shadowing.
22161 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22163 * deps.mk (unexalpha.o): Remove; unused.
22165 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22166 * unexec.h: New file.
22167 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):

22229 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22230 some of which prompt warnings from gcc -Wbad-function-cast.
22231 (Fformat_time_string, Fencode_time, Finsert_char):

22260 (Fmemory_limit): Cast sbrk's returned value to char *.
22262 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22265 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22267 Use functions, not macros, for up- and down-casing (Bug#8254).
22268 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):

22270 to use the following functions instead of these macros.
22271 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22272 EMACS_INT, since callers assume the returned value fits in int.
22273 (upcase1): Likewise, for UPCASE_TABLE.
22274 (uppercasep, lowercasep, upcase): New static inline functions.
22275 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22285 (regex_compile, re_match_2_internal): Mark locals as initialized.
22286 (RETALLOC_IF): Define only if needed.
22287 (WORDCHAR_P): Likewise. This one is never needed, but is used
22288 only in a comment talking about a compiler bug, so put inside
22289 the #if 0 of that comment.
22290 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22291 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22317 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22318 New macros, so that the caller can use some names other than
22319 gcpro1, gcpro2, etc.
22320 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22322 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22323 argument, for consistency with GCPRO2_VAR, etc: it is now the
22324 prefix of the variable, not the variable itself. All uses
22326 * dired.c (directory_files_internal, file_name_completion):
22327 Rename locals to avoid shadowing.
22329 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22330 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22331 dired.c's scmp function, had undefined behavior.
22332 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22333 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22334 * buffer.h: ... to here, because these macros use current_buffer,
22335 and the new implementation with inline functions needs to have
22336 current_buffer in scope now, rather than later when the macros
22338 (downcase, upcase1): New static inline functions.
22339 (DOWNCASE, UPCASE1): Reimplement using these functions.
22340 This avoids undefined behavior in expressions like
22341 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22342 from race conditions in accessing the global variables
22343 case_temp1 and case_temp2.
22344 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22345 * lisp.h (case_temp1, case_temp2): Remove their decls.
22346 * character.h (ASCII_CHAR_P): Move from here ...

22355 (file_name_as_directory): Use const pointers when appropriate.
22356 (Fexpand_file_name): Likewise. In particular, newdir might
22357 point at constant storage, so make it a const pointer.

22359 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22361 (Fset_file_times, Finsert_file_contents, auto_save_error):

22366 to avoid shadowing.
22368 * marker.c (bytepos_to_charpos): Remove; unused.
22370 * lisp.h (verify_bytepos, count_markers): New decls,
22371 so that gcc does not warn that these functions aren't declared.
22373 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22374 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22375 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22376 (copy_text): Remove unused local var.

22379 (lock_file_1): Rename local to avoid shadowing.
22381 * buffer.c (fix_overlays_before): Mark locals as initialized.
22382 (fix_start_end_in_overlays): Likewise. This function should be
22383 simplified by using pointers-to-pointers, but that's a different

22386 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22387 (report_overlay_modification): Rename locals to avoid shadowing.

22392 to suppress a gcc -Wclobbered warning that does not seem to be right.
22393 (MAXPATHLEN): Define only if needed.
22395 * process.c (serial_open, serial_configure): Move decls from here ...
22396 * systty.h: ... to here, so that they can be checked.
22398 * fns.c (get_random, seed_random): Move extern decls from here ...
22399 * lisp.h: ... to here, so that they can be checked.
22401 * sysdep.c (reset_io): Now static.

22560 For example, without this patch (encode-time 0 0 0 1 1
22561 1152921504606846976) returns the obviously-bogus value (-948597
22562 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22563 reports time overflow. See
