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

143 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
144 * sysdep.c (list_system_processes)
145 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
146 Make it a stub in this case; otherwise the build might fail,
147 and this code hasn't been tested on such hosts anyway.
148 Problem reported by Nelson H. F. Beebe in
149 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
150 and analyzed by Jérémie Courrèges-Anglas in

161 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
163 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
164 * filelock.c: Include <c-ctype.h>.
165 (MAX_LFINFO): New top-level constant.
166 (lock_info_type): Remove members pid, boot_time. Add members at,
167 dot, colon. Change user member to be the entire buffer, not a
168 pointer. This allows us to handle the case where a foreign
169 pid or boot time exceeds the local range. All uses changed.
170 (LINKS_MIGHT_NOT_WORK): New constant.
171 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
172 (defined_WINDOWSNT): Remove.
173 (MAKE_LOCK_NAME, file_in_lock_file_name):
174 Always use .#FILE (not .#-FILE) for the file lock,
175 even if it is a regular file.
176 (rename_lock_file): New function.
177 (create_lock_file): Use it.
178 (create_lock_file, read_lock_data):
179 Prefer a symbolic link for the lock file, falling back on a
180 regular file if symlinks don't work. Do not try to create
181 symlinks on MS-Windows, due to security hassles. Stick with
182 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
183 link, rename, unlink, mkstemp) when creating locks, as a GNUish
184 host may be using a Windowsish file system, and cannot use
185 MS-Windows-only system calls. Fall back on mktemp if mkstemp
186 doesn't work. Don't fail merely because of a symlink-contents
187 length limit in the current file system; fall back on regular
188 files. Increase the symlink contents length limit to 8 KiB, this
189 should be big enough for any real use and doesn't crunch the
191 (create_lock_file, lock_file_1, read_lock_data):
192 Simplify allocation of lock file buffers now that they fit in 8 KiB.
193 (lock_file_1): Return error number, not bool. All callers changed.
194 (ELOOP): New macro, if not already defined.
195 (read_lock_data): Return size of lock file contents, not Lisp object.
196 All callers changed. Handle a race condition if some other process
197 replaces a regular-file lock with a symlink lock or vice versa,
198 while we're trying to read the lock.
199 (current_lock_owner): Parse contents more carefully, to help avoid
200 confusing a regular-file lock with some other application's use
201 of the file. Check for lock file contents being too long, or
202 not parsing correctly.
203 (current_lock_owner, lock_file):
204 Allow foreign pid and boot times that exceed the local range.
205 (current_lock_owner, lock_if_free, lock_file):
206 Simplify allocation of lock file contents.
207 * w32.c (sys_rename_replace): New function, containing most of
208 the contents of the old sys_rename.
209 (sys_rename): Use it.
210 (fchmod): New dummy function.
211 * w32.h (sys_rename_replace, fchmod): New decls.
213 2013-03-05 Eli Zaretskii <eliz@gnu.org>
215 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
216 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
217 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
218 <dmantipov@yandex.ru>.
220 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
222 * composite.c (get_composition_id, fill_gstring_header):
223 Use make_uninit_vector where appropriate.
224 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
225 * xselect.c (clean_local_selection_data): Likewise.
227 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
229 Fix misuse of ImageMagick that caused core dump (Bug#13846).
230 * image.c (imagemagick_load_image): Calculate height and width
231 after flattening the image, not before.
233 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
235 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
236 * ftfont.c (ftfont_shape_by_flt): Likewise.
237 * w32uniscribe.c (uniscribe_shape): Likewise.
239 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
241 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
242 The old approach, which fell back on DIR/.#FILE.0 through
243 DIR/.#FILE.9, had race conditions that could not be easily fixed.
244 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
245 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
246 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
247 because the locking mechanism was never reliable in that case).
248 This patch fixes this and other bugs discovered by a code
249 inspection that was prompted by
250 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
251 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
252 to avoid interoperability problems between the MS-Windows and
253 non-MS-Windows implementations. MS-Windows and non-MS-Windows
254 instances of Emacs now ignore each others' locks.
255 * filelock.c (defined_WINDOWSNT): New constant.
256 (MAKE_LOCK_NAME, fill_in_lock_file_name):
257 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
258 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
259 regular files on MS-Windows hosts.
260 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
261 Use SAFE_ALLOCA to avoid problems with long file names.
262 (MAX_LFINFO): Now a local constant, not a global macro.
263 (IS_LOCK_FILE): Remove.
264 (lock_file_1): Don't inspect errno if symlink call succeeds;
266 (lock_file): Document that this function can return if lock
268 (lock_file): Don't access freed storage.
270 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

274 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
276 * textprop.c: Use bool for booleans.
277 (validate_interval_range, Fadd_text_properties)
278 (Fremove_text_properties): Prefer bool to int when either works.
280 2013-03-02 Eli Zaretskii <eliz@gnu.org>
282 * textprop.c (Fadd_text_properties, Fremove_text_properties):
283 If the interval tree changes as a side effect of calling
284 modify_region, re-do processing starting from the call to
285 validate_interval_range. (Bug#13743)
287 2013-02-28 Eli Zaretskii <eliz@gnu.org>
289 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
292 2013-02-27 Eli Zaretskii <eliz@gnu.org>
294 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
295 _SH_DENYRW flag, instead of emacs_open, to deny any other process
296 access to the lock file until it is written and closed.
299 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
301 * callint.c (Qcall_interactively):
302 * macros.c (Qexecute_kbd_macro):
305 2013-02-26 Bastien Guerry <bzg@gnu.org>
307 * window.c (Frecenter): Tiny docstring enhancement.
309 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
311 Minor textprop integer cleanup.
312 * intervals.h, textprop.c (add_text_properties_from_list):
313 Return void, not int, since nobody uses the return value.
314 * textprop.c (validate_plist, add_properties, remove_properties)
315 (Fadd_text_properties):
316 Don't assume list length fits in int.
317 (interval_has_all_properties, interval_has_some_properties)
318 (interval_has_some_properties_list, add_properties, remove_properties)
319 (Fadd_text_properties, Fremove_text_properties)
320 (Fremove_list_of_text_properties, text_property_stickiness):
321 Use bool for booleans.
322 (Fadd_text_properties, Fremove_text_properties):
323 (Fremove_list_of_text_properties):
324 Reindent do-while as per GNU style.
326 2013-02-25 Eli Zaretskii <eliz@gnu.org>
328 Implement CLASH_DETECTION for MS-Windows.
330 * filelock.c [WINDOWSNT]: Include w32.h.
331 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
332 function of that name. Up-case the macro arguments.
333 (IS_LOCK_FILE): New macro.
334 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
335 (create_lock_file): New function, with body extracted from
337 [WINDOWSNT]: Implement lock files by writing a regular file with
338 the lock information as its contents.
339 (read_lock_data): New function, on Posix platforms just calls
341 [WINDOWSNT]: Read the lock info from the file.
342 (current_lock_owner): Call read_lock_data instead of calling
343 emacs_readlinkat directly.
344 (lock_file) [WINDOWSNT]: Run the file name through
347 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
348 just check if the process by that PID exists.
350 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
351 also present, as doing so will fail to error out if the file
354 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
356 * textprop.c (Fadd_text_properties, Fremove_text_properties)
357 (Fremove_list_of_text_properties): Skip all of the intervals in
358 the region between START and END that already have resp. don't
359 have the requested properties, not just the first one.
360 Add assertions that the loop afterwards always modifies the
361 properties. (Bug#13743)

470 * xdisp.c (x_draw_vertical_border): For a window that is neither
471 the leftmost nor the rightmost, redraw both the left and the right
472 vertical borders. (Bug#13723)

492 2013-02-16 Eli Zaretskii <eliz@gnu.org>
494 * w32.c (sys_chown): Remove unused function.
496 * w32term.c <input_signal_count>: Declare 'volatile'
497 unconditionally. (Bug#9066)
499 * w32.c (set_errno): Reset h_errno and don't set it to any other
500 value. Set errno instead.
501 (check_errno): Reset h_errno.

509 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
511 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
513 2013-02-15 Eli Zaretskii <eliz@gnu.org>
515 * keyboard.c (read_char): Fix calculation of auto-save time out
516 when auto-save-timeout is less than 4. (Bug#13720)
518 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

525 make sure errno is set to an appropriate value. (Bug#13546)
526 (socket_to_fd): Add assertion against indexing fd_info[] with a
527 value that is out of bounds.
528 (sys_accept): If fd is negative, do not set up the child_process
529 structure for reading.
531 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
533 * composite.c (fill_gstring_header): Remove useless prototype.

545 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
547 Fix AIX port (Bug#13650).
548 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
549 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
550 was #undeffed earlier, so it cannot be used as a macro here.
551 Use the constant and not the macro.
553 2013-02-15 Eli Zaretskii <eliz@gnu.org>
555 * w32proc.c (new_child): If no vacant slots are found in
556 child_procs[], make another pass looking for slots whose process
557 has exited or died. (Bug#13546)
559 * w32.c (sys_pipe): When failing due to file descriptors above
560 MAXDESC, set errno to EMFILE.
561 (_sys_read_ahead): Update cp->status when failing to read serial
562 communications input, so that the status doesn't stay at
563 STATUS_READ_IN_PROGRESS. (Bug#13546)
565 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
567 * gtkutil.c (tb_size_cb): New function.

575 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
577 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
579 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
581 * font.c (font_range): Add pos_byte argument. Adjust comment
583 * font.h (font_range): Adjust prototype.
584 * composite.c (autocmp_chars): Pass byte position to font_range.

587 2013-02-13 Glenn Morris <rgm@gnu.org>
589 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
591 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
593 Improve AIX port some more (Bug#13650).
594 With this, it should be as good as it was in 23.3, though it's
595 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
596 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
597 * unexaix.c (start_of_text): Remove.
598 (_data, _text): Declare as char[], not int, as AIX manual suggests.
599 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
600 (orig_load_scnptr, orig_data_scnptr):
601 Now off_t, not long, since they are file offsets.
602 (make_hdr): Use _data, not start_of_data ().
603 This is the key part of the fix.
604 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
605 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
607 * pre-crt0.c (data_start): Initialize to 1.
608 This ports to compilers that optimize the external declaration
609 'int x = 0;' as if it were 'int x;' to shrink the executable.
611 Improve AIX port (Bug#13650).
612 This doesn't fix the bug, but it makes progress: Emacs builds now.
613 * unexaix.c: Include inttypes.h, stdarg.h.
614 (report_error, report_error_1): Mark as _Noreturn.
615 (report_error): Don't report the wrong errno.
616 (report_error_1): Now varargs. All callers changed.
617 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
618 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
619 (write_ptr): Use %p to print address rather than %lx and a cast
620 to unsigned long. Grow buffer a bit, to be safer.
622 2013-02-13 Eli Zaretskii <eliz@gnu.org>
624 * bidi.c (bidi_resolve_neutral): After finding the next
625 non-neutral character, accept NEUTRAL_ON type as well, because
626 directional control characters, such as LRE and RLE, have their
627 type converted to that by bidi_resolve_weak. This avoids aborts
628 when LRE/RLE follows a run of neutrals.
629 (bidi_move_to_visually_next): Assert that return value of
630 bidi_peek_at_next_level is non-negative. Negative values will
633 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
635 Minor getenv-related fixes.
636 * callproc.c (Fcall_process_region) [!DOS_NT]:
637 Avoid unnecessary duplicate call to getenv.
638 * callproc.c (init_callproc):
639 * dispnew.c (init_display):
640 * sysdep.c (sys_subshell):
641 Omit unnecessary cast of getenv or egetenv.
643 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
645 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
648 2013-02-12 Eli Zaretskii <eliz@gnu.org>
650 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
652 (display_line): Set w->region_showing to the value of
653 it->region_beg_charpos, not to -1. This fixes redisplay
654 optimization when cursor is moved up after M->. (Bug#13623)
656 (try_scrolling): Scroll text up more if point is too close to ZV
657 and inside the scroll margin. This makes sure point is moved
658 outside the scroll margin in these cases.
660 * window.h (struct window): region_showing can no longer be
663 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
665 Tune by using memchr and memrchr.
666 * doc.c (Fsnarf_documentation):
667 * fileio.c (Fsubstitute_in_file_name):
668 * search.c (find_newline, scan_newline):
669 * xdisp.c (pos_visible_p, display_count_lines):
670 Use memchr and memrchr rather than scanning byte-by-byte.
671 * search.c (find_newline): Rename from scan_buffer.
672 Omit first arg TARGET, as it's always '\n'. All callers changed.
674 Clean up read_key_sequence a tiny bit more.
675 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
676 (read_key_sequence): Remove unused locals.
678 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
680 Clean up read_key_sequence a bit; reread active keymaps after first event.
681 * keyboard.c (read_char, read_char_x_menu_prompt)
682 (read_char_minibuf_menu_prompt):
683 Replace nmaps+maps with a single `map' arg.
684 (follow_key): Operate on a single map.
685 (active_maps): New function.
686 (test_undefined): Also return true for nil bindings.
687 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
688 a single (composed) keymap. Remember `first_event' to choose the right
689 set of active keymaps. Recompute the set of keymaps after receiving
690 the first event. Remove GOBBLE_FIRST_EVENT.
691 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
692 * keyboard.h (read_char): Update declaration.
693 * lread.c (read_filtered_event): Adjust call to read_char.
695 2013-02-11 Eli Zaretskii <eliz@gnu.org>
697 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
698 Don't use the limitation on backwards movement when lines are truncated
699 in the window. (Bug#13675)
701 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
703 * marker.c (set_marker_internal): If desired position is passed
704 as a marker, avoid call to buf_charpos_to_bytepos.
705 * window.c (Fset_window_point): Omit redundant type checking.
706 (Fset_window_start): Likewise. Format comment.
707 (window_scroll_pixel_based): Use set_marker_restricted_both
708 with character and byte positions obtained from an iterator.
709 (Fset_window_configuration): Use set_marker_restricted_both.
710 * xdisp.c (message_dolog): Likewise.
712 2013-02-10 Eli Zaretskii <eliz@gnu.org>
714 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
715 When text lines are longer than window's screen lines, don't move back
716 too far. This speeds up some redisplay operations. (Bug#13675)
718 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
720 * syntax.c (scan_sexps_forward): Fix byte position calculation
721 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
723 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
725 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
728 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
730 Minor hashing refactoring.
731 * fns.c (SXHASH_REDUCE): Move to lisp.h.
732 (sxhash_float): Return EMACS_UINT, for consistency with the other
734 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
735 non-static inline function and therefore can't use static vars.
736 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
737 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
738 with the other hash functions.
740 2013-02-09 Eli Zaretskii <eliz@gnu.org>
742 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
743 XXXXXX part of the temporary file pattern is not downcased even
744 when w32-downcase-file-names is non-nil. (Bug#13661)
746 * xdisp.c (decode_mode_spec): Remove handling of %t.
748 * msdos.c (careadlinkatcwd): Remove.
750 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
752 * lread.c (skip_dyn_bytes): New function (bug#12598).
753 (read1): Use it. Use getc instead of READCHAR to read bytes.
754 (load_each_byte): Remove. Update users.
756 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
758 * search.c (scan_buffer): Calculate end byte position just once.
759 (scan_newline): Do not recalculate start_byte.
760 (search_command): Use eassert.
761 * syntax.c (struct lisp_parse_state): New member location_byte.
762 (scan_sexps_forward): Record from_byte and avoid redundant
763 character to byte position calculation ...
764 (Fparse_partial_sexp): ... here. Break too long line.
766 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
768 * lisp.h (make_uninit_vector): New function.
769 * alloc.c (Fvector, Fmake_byte_code):

781 * window.c (Fcurrent_window_configuration):
782 * xfaces.c (Fx_family_fonts):
783 * xselect.c (selection_data_to_lisp_data): Use it.
785 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
787 * coding.c (Fdefine_coding_system_internal): Use AREF where
788 argument is known to be a vector.
789 * fns.c (Flocale_info): Likewise for ASET.
790 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
791 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
793 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
795 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
798 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
799 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
800 updateCollectionBehaviour.
802 * nsterm.m (NEW_STYLE_FS): Remove.
803 (ns_last_use_native_fullscreen): New variable.
804 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
805 (x_set_window_size): Do not take title bar and tool bar into account
806 if isFullscreen returns YES.
807 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
808 (check_native_fs): New function.
809 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
810 (ns_term_init): Remove NEW_STYLE_FS.
811 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
812 and tool bar if isFullscreen returns NO.
813 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
814 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
816 (window:willUseFullScreenPresentationOptions:): New method.
817 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
818 Hide toolbar if not enabled (Bug#13444).
819 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
820 Restore tool bar if enabled, hide it otherwise (Bug#13444).
821 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
822 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
823 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
824 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
825 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
826 (syms_of_nsterm): Add ns-use-native-fullscreen.
828 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
830 * fileio.c (Qchoose_write_coding_system): Now static.
832 2013-02-04 Eli Zaretskii <eliz@gnu.org>
834 * xdisp.c (window_buffer_changed): region_showing can be negative,
835 which still means region is being displayed.
836 (redisplay_internal): Resurrect code that forced redisplay of the
837 whole window when showing region and the mark has changed.
838 Record the new mark position to allow redisplay optimizations.
839 (display_line): If it->region_beg_charpos is non-zero, set the
840 window's region_showing member to -1. (Bug#13623) (Bug#13626)
842 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
843 not bitfield of 1 bit.
845 2013-02-03 Daniel Colascione <dancol@dancol.org>
847 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
848 daemon mode works on cygw32 when Emacs is installed and not just
851 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
853 Avoid file time stamp bug on MS-Windows (Bug#13149).
854 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
855 as FAT32 doesn't update time stamps when truncating them.
856 Also, check that a file time stamp is not a multiple of 100 ns;
857 this should catch all instances of the problem on MS-Windows,
858 as its native file system resolution is 100 ns or worse, and
859 checking for a non-multiple of 100 ns should impose only a small
860 overhead on systems with ns resolution.
862 2013-02-02 Eli Zaretskii <eliz@gnu.org>
864 Avoid encoding file names on MS-Windows when they need to be run
865 through dostounix_filename.
866 * w32.c (normalize_filename): Accept an additional argument
867 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
868 downcase it even if w32-downcase-file-names is non-nil.
869 (dostounix_filename): Accept an additional argument MULTIBYTE and
870 pass it to normalize_filename.
871 (emacs_root_dir): Adjust.
873 * msdos.h (dostounix_filename): Adjust prototype.
875 * w32.h (dostounix_filename): Adjust prototype.
877 * msdos.c (dostounix_filename): Accept an additional argument and
879 (init_environment): Adjust callers of dostounix_filename.
881 * fileio.c (Ffile_name_directory, file_name_as_directory)
882 (directory_file_name, Fexpand_file_name)
883 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
885 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
887 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
888 variables, as egetenv is case-insensitive for DOS_NT.
890 * dired.c (file_name_completion): Don't call Fdirectory_file_name
891 with an encoded file name.
893 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
894 Adjust calls to dostounix_filename.
896 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
898 * unexw32.c (unexec): Adjust call to dostounix_filename.
900 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
902 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
905 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
908 * callproc.c (Fcall_process): Make sure program name in PATH and
909 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
910 is passed to exec/spawnve, which fails unless the file-name
913 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
914 even if w32-quote-process-args is nil.
916 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
918 Fix timestamp bug when write-region appends nothing (Bug#13149).
919 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
920 the file's time stamp doesn't change if Emacs happens to write nothing
921 to the file, and on a buggy file system this could cause Emacs to
922 incorrectly infer that the file system doesn't have the bug.
923 Avoid this problem by inhibiting the inference in this case.
925 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
927 * window.h (struct window): Convert base_line_number, base_line_pos
928 and column_number_displayed members from Lisp_Object to ptrdiff_t.
929 Convert region_showing member from Lisp_Object to bitfield.
930 Remove sequence_number member. Adjust comments.
931 * window.c (sequence_number): Remove.
932 (make_window): Initialize column_number_displayed.
933 * print.c (print_object): Follow the printed representation of
934 frames and print window pointer to distinguish between windows.
935 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
936 * xdisp.c (wset_base_line_number, wset_base_line_pos)
937 (wset_column_number_displayed, wset_region_showing): Remove.
938 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
939 (try_scrolling, try_cursor_movement, redisplay_window)
940 (try_window_reusing_current_matrix, try_window_id, display_line)
941 (display_mode_lines, decode_mode_spec): Adjust users.
942 * .gdbinit (pwinx): Do not print sequence_number.
944 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
946 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
947 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
948 * dired.c: Include <fcntl.h>.
949 (open_directory): New function, which uses open and fdopendir
950 rather than opendir. DOS_NT platforms still use opendir, though.
951 (directory_files_internal, file_name_completion): Use it.
952 (file_attributes): New function, with most of the old Ffile_attributes.
953 (directory_files_internal, Ffile_attributes): Use it.
954 (file_attributes, file_name_completion_stat): First arg is now fd,
955 not dir name. All uses changed. Use fstatat rather than lstat +
957 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
958 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
959 (emacs_readlinkat): New function, with much of the old
960 Ffile_symlink_p, but with an fd argument for speed.
961 It uses readlinkat rather than careadlinkatcwd, so that it
962 need not assume the working directory.
963 (Ffile_symlink_p): Use it.
964 * filelock.c (current_lock_owner): Use emacs_readlinkat
965 rather than emacs_readlink.
966 * lisp.h (emacs_readlinkat): New decl.
967 (READLINK_BUFSIZE, emacs_readlink): Remove.
968 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
969 (emacs_norealloc_allocator, emacs_readlink): Remove.
970 This stuff is moved to fileio.c.
971 * w32.c (fstatat, readlinkat): New functions.
972 (careadlinkat): Don't check that fd == AT_FDCWD.

982 2013-01-30 Eli Zaretskii <eliz@gnu.org>
984 * w32.c (sys_open): Zero out the flags for the new file descriptor.
985 (sys_close): Zero out the flags for the file descriptor before
986 closing it. (Bug#13546)
988 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
989 (logon_network_drive, stat_worker, symlink, chase_symlinks):
990 Use CharNextExA and CharPrevExA to iterate over file names encoded in
993 * w32.c (w32_get_long_filename, init_environment, readlink):
994 Support file names encoded in DBCS codepages.
995 (readlink): Use the current file-name-coding-system, not the ANSI
996 codepage, to decode and handle targets of symlinks.
998 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1000 * w32.c (opendir): Now accepts a 'const char *'.
1002 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1004 Remove obsolete redisplay code. See the discussion at
1005 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1006 * dispnew.c (preemption_period, preemption_next_check): Remove.
1007 (Vredisplay_preemption_period): Likewise.
1008 (update_frame, update_single_window, update_window, update_frame_1):
1009 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1010 used, following the 2012-06-22 change.
1012 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1014 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1016 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1018 * font.c (num_fonts): Remove the leftover from old
1019 debugging code. Adjust comment style here and there.
1020 * insdel.c (insert_1): Remove.
1021 * lisp.h (insert_1): Remove prototype.

1024 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1026 * w32.c (max_filename_mbslen): New function.
1027 (normalize_filename, readdir): Use it to detect locales where ANSI
1028 encoding of file names uses a double-byte character set (DBCS).
1029 If a DBCS encoding is used, advance by characters using
1030 CharNextExA, instead of incrementing a 'char *' pointer.
1031 Use _mbslwr instead of _strlwr. (Bug#13515)
1033 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1034 request of memory reservation to 1.7GB. (Bug#13065)
1036 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1038 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1039 at check_extra_latin label. (Bug#13505)
1041 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1043 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1044 Avoid redundant calls to strlen.
1046 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1048 Drop async_visible and async_iconified fields of struct frame.
1049 This is possible because async input is gone; for details, see
1050 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1051 * frame.h (struct frame): Remove async_visible and async_iconified
1052 members, convert garbaged to unsigned bitfield. Adjust comments.
1053 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1054 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1055 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1056 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1057 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1059 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1060 properly. Likewise for obscured.
1062 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1065 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1067 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1069 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1070 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1072 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1074 * xdisp.c (message2, message2_nolog): Remove functions.
1075 (message3, message3_nolog): Extract nbytes and multibyteness directly
1076 from the string. Change all callers.
1077 (message3_nolog): Don't set message_enable_multibyte since set_message
1078 will reset it anyway.
1079 (message1, message1_nolog): Use message3.
1080 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1081 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1082 (set_message): Drop all but the second arg, which has to be a string.
1083 (set_message_1): Simplify now that we know that a1 is NULL and the
1084 second arg is a string.
1085 * frame.h (struct frame): Remove `message_buf' field.
1086 Use glyphs_initialized_p instead.
1087 (FRAME_MESSAGE_BUF): Remove macro.
1088 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1089 * lisp.h (message2, message2_nolog): Remove declarations.
1090 (message3, message3_nolog): Update declarations.
1091 * keyboard.c (read_char_minibuf_menu_text)
1092 (read_char_minibuf_menu_width): Remove vars.
1093 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1094 to correctly handle multibyte strings.
1095 * frame.c (delete_frame): Don't free message_buf any more.
1096 * editfns.c (message_text, message_length): Remove vars.
1097 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1098 * fileio.c (auto_save_error): Use message3 instead of message2.
1099 * dispnew.c (adjust_frame_message_buffer): Remove function.
1101 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1103 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1104 real estate used for the tool bar and the menu bar.
1106 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1108 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1109 hidden buffer is prepared to modification (Bug#13164).
1111 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1113 * window.h (struct window): Change window_end_valid member from
1114 Lisp_Object to a bitfield. Adjust comments.
1115 (wset_window_end_valid): Remove.
1116 * window.c (adjust_window_count): Clear window_end_valid.
1117 (Fwindow_end): Adjust user. Remove ancient #if 0 code.

1120 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1121 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1122 * xdisp.c (check_window_end, reconsider_clip_changes)
1123 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1124 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1125 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1127 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1129 * xdisp.c (mark_window_display_accurate): Simplify the loop
1130 assuming that the only one of vchild, hchild or buffer window
1131 slots is non-nil. Call mark_window_display_accurate_1 for
1132 the leaf windows only.
1133 (mark_window_display_accurate_1): Always assume leaf window.
1136 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1138 * emacs.c (Qkill_emacs_hook): Now static.
1140 * fileio.c (Finsert_file_contents): Simplify.
1141 Remove unnecessary assignments and tests.
1143 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1145 * w32.c (acl_set_file): Don't test for errors unless
1146 set_file_security returns FALSE. Avoids spurious errors when
1149 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1151 * fileio.c (Finsert_file_contents): Revert code introduced at
1152 2013-01-18 in favor of the simpler and generally better fix.
1153 Save stack space by removing 'buffer' and reusing 'read_buf'
1156 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1158 * lisp.h (eabs): Define unconditionally (Bug#13419).
1159 The old "#if !defined (eabs)" was an unnecessary revenant of back
1160 when this macro was called "abs". Document 'eabs' better.
1162 2013-01-19 Glenn Morris <rgm@gnu.org>
1164 * fns.c (Frandom): Doc fix.
1166 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1168 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1169 segfault when there are lots of overlays.
1171 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1172 when there are lots of overlays.
1173 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1174 for the details and a way to reproduce.
1176 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1178 * fileio.c: Use O_APPEND to append.
1179 This corresponds better to the natural interpretation of "append",
1180 and avoids the need to open the output file twice, or to invoke
1181 lseek when APPEND is neither nil nor a number.
1182 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1183 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1184 file possibly twice, and lseeking to its end; this avoids the
1185 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1186 at the same time: the combination is never needed and apparently
1187 it doesn't work with DOS_NT.
1189 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1190 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1192 Allow floating-point file offsets.
1193 Problem reported by Vitalie Spinu in
1194 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1195 * fileio.c (emacs_lseek): Remove.
1196 (file_offset): New function.
1197 (Finsert_file_contents, Fwrite_region): Use it.
1199 2013-01-19 Chong Yidong <cyd@gnu.org>
1201 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1202 aborting on Fsignal (Bug#13289).
1204 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1206 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1207 set_file_security as failure due to insufficient privileges.
1208 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1209 (fstat): Return owner and group like 'stat' and 'lstat' do.
1211 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1213 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1214 The bug was observed on Ubuntu operating inside a virtual machine,
1215 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1216 The workaround introduces a race condition on non-buggy hosts,
1217 but it's an unlikely race and anyway there's a nearly identical
1218 nearby race that can't be fixed.
1219 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1221 (Fwrite_region): Test for file system time stamp bug.
1222 (init_fileio): New function.
1223 * lisp.h (init_fileio): Declare it.
1224 * emacs.c (main): Call it.
1226 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1227 and make it more consistent with other stat-failure diagnostics.
1229 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1231 Fix crash when inserting data from non-regular files.
1232 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1233 for the error description produced by valgrind.
1234 * fileio.c (read_non_regular): Rename to read_contents.
1235 Free Lisp_Save_Value object used to pass parameters.
1236 (read_non_regular_quit): Rename to read_contents_quit.
1237 (Finsert_file_contents): Redesign internal file reading loop to adjust
1238 gap and end positions after each read and so help make_gap to work
1239 properly. Do not signal an I/O error too early and so do not leave
1240 not yet decoded characters in a buffer, which was the reason of
1241 redisplay crash. Use list2 to build return value. Adjust comments.
1243 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1245 Close a race when statting and reading files (Bug#13149).
1246 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1247 This avoids a race if the file is renamed between stat and open.
1248 This race is not the problem originally noted in Bug#13149;
1249 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1251 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1258 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1259 * alloc.c (format_save_value): Rename to make_save_value.
1260 (make_save_pointer): New function.
1261 (record_xmalloc): Use make_save_pointer.
1262 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1263 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1264 Change users of make_save_value to make_save_pointer.

1281 (map_keymap_char_table_item): Adjust accordingly.
1282 * fileio.c (non_regular_fd, non_regular_inserted)
1283 (non_regular_nbytes): Remove.
1284 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1285 Use format_save_value to pass parameters to read_non_regular.
1286 (read_non_regular): Use XSAVE_ macros to extract parameters.
1288 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1290 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1292 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1294 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1295 extraction from any Lisp_Save_Value slot. Add type checking.
1296 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1297 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1298 * xselect.c: All users changed.
1300 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1311 (save_excursion_restore): Use XSAVE_OBJECT.
1313 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1315 Avoid needless casts with XSAVE_POINTER.
1316 * alloc.c (mark_object) [GC_MARK_STACK]:
1317 * dired.c (directory_files_internal_unwind):
1318 * fileio.c (do_auto_save_unwind):
1319 * gtkutil.c (pop_down_dialog):
1320 * keymap.c (map_keymap_char_table_item):
1321 * lread.c (load_unwind):
1322 * nsmenu.m (pop_down_menu):
1323 * print.c (print_object) [GC_MARK_STACK]:
1324 * xfns.c (clean_up_file_dialog):
1325 * xmenu.c (cleanup_widget_value_tree):
1326 Omit casts between XSAVE_POINTER and a pointer type.
1328 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1330 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1331 * eval.c (eval_sub): Protect `form' from being GCed before its
1332 car and cdr becomes protected with the backtrace entry.
1334 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

1344 (free_misc): Likewise. Adjust comment.
1345 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1346 (free_save_value): Likewise.
1347 (mark_object): Likewise.
1348 * editfns.c (save_excursion_save): Pack everything within
1349 Lisp_Save_Value and so avoid xmalloc.
1350 (save_excursion_restore): Adjust to match new layout. Use free_misc
1351 because we do not allocate extra memory any more. Add eassert.
1352 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1353 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1354 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,

1367 Fix SIGDANGER handlers, for AIX (Bug#13408).
1368 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1369 Move handlers here from emacs.c; they were out of place.

1421 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1423 Avoid unnecessary byte position calculation for the gap movement.
1424 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1425 anyway, all of them should use move_gap_both instead.
1426 * lisp.h (move_gap): Remove prototype.
1427 * insdel.c (move_gap): Remove.

1434 emacsclient -t should not suspend Emacs server (Bug#13387)
1435 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1437 * term.c (init_tty): Use them instead of rolling our own code.
1438 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1439 switches from 'signal' to 'pthread_sigmask', which is safer in
1440 multithreaded applications.
1441 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1442 which has already arranged for that.
1443 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1444 This is the main part of the bug fix.

1456 predicate, which is how it's really used now. Adjust comment.
1457 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1458 * buffer.c (buffer_slot_type_mismatch): Remove.
1459 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1460 predicate. Adjust comment.

1464 right-fringe-width, scroll-bar-width and buffer-display-count.
1465 Use Qstringp for default-directory, buffer-file-name,
1466 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1467 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1469 * data.c (store_symval_forwarding): Adjust to call the predicate.

1485 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1486 (make_gap_1): New function to adjust the gap of any buffer.
1487 * coding.c (coding_alloc_by_making_gap): Use it.
1488 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1489 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

1512 trailing dash is properly added.
1514 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1516 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1517 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1518 digits for buffer positions, before misalignment starts.
1519 Display "0" for integer "object" field.
1520 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1521 Display the newline glyph more unambiguously.
1523 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1525 * nsterm.m (ns_draw_underwave):
1526 * w32term.c (w32_draw_underwave):
1527 * xterm.c (x_draw_underwave): Make underwave look more triangular
1528 and also degrade gracefully for small fonts. (Bug#13000)
1530 * nsterm.m (ns_draw_text_decoration):
1531 * w32term.c (x_draw_glyph_string):
1532 * xterm.c (x_draw_glyph_string): Don't use previous underline
1533 thickness and position if previous underline type is underwave.
1535 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1537 * fileio.c (Ffile_acl): Undocument return format.
1539 2013-01-02 Glenn Morris <rgm@gnu.org>

1552 * minibuf.c (Ftry_completion):
1553 * term.c (tty_ins_del_lines):
1554 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1555 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1557 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1559 * w32.c (unsetenv): Set up the string passed to _putenv
1561 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1562 for the bug this caused.
1564 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1566 * coding.c (Qmac): Now static.
1568 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1570 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1571 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1575 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1576 Show all on TOOLBAR_TOP_WIDGET.
1577 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1578 by TOOLBAR_TOP_WIDGET.
1579 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1580 Check toolbar_is_packed.
1581 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1586 (xg_update_menubar): Update title only if
1587 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1588 (xg_update_submenu): Skip tearoff only if
1589 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1590 (xg_initialize): Initialize xg_detached_menus only if
1591 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1593 * xterm.h (struct x_output): Surround handlebox_widget with
1594 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1595 toolbar_in_hbox is bool.
1597 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1599 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1600 (LIBS_GNUSTEP): Define.
1601 (LIBES): Add $(LIBS_GNUSTEP).

1604 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1606 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1607 continuation glyph on a TTY with an indication of an empty line.
1610 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1612 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1613 file's SELinux context or ACLs successfully set, nil otherwise.
1615 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

1618 SetEvent and WaitForSingleObject.
1620 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1622 Port EXTERNALLY_VISIBLE to Clang 3.2.
1623 * conf_post.h (__has_attribute): New macro.
1624 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1626 2012-12-27 Glenn Morris <rgm@gnu.org>
1628 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1629 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1631 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1633 * fileio.c (file_name_as_directory, directory_file_name):
1634 Accept an additional argument MULTIBYTE to indicate whether the input C
1635 came from a multibyte or a unibyte Lisp string; all callers
1636 adjusted. Don't assume the input string is always multibyte.
1638 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1639 don't ENCODE_FILE them, and return a unibyte string if the input
1641 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1642 don't assume the input strings will always be multibyte. If the
1643 input strings are multibyte, decode strings obtained from C
1646 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1648 * lisp.h (toplevel): Add two notices to the comment about
1649 defining a new Lisp data type.

1653 * alloc.c (valid_lisp_object_p): Adjust comment.
1655 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1657 * keyboard.c (record_asynch_buffer_change): Initialize an event
1658 only if it's really needed.
1659 * frame.h (enum output_method): Remove output_mac member since
1660 it's a leftover from the deleted code.
1661 * frame.c (Fframep): Adjust user here ...
1662 * terminal.c (Fterminal_live_p): ... and here.
1663 * coding.c (Qmac): Now here because it's only used to denote
1664 end-of-line encoding type.
1665 (syms_of_coding): DEFSYM it.
1666 * frame.h (Qmac): Remove duplicated declaration.
1668 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1670 * window.c (select_window_1): Now static, since it's used only here.
1672 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1674 * window.c (window_body_cols): Subtract display margins from the
1675 window body width on TTYs as well. See
1676 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1677 for the original report.
1679 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1681 * xdisp.c (redisplay_window): Remove inner local variable
1682 because the outer shadowed one has the same meaning.
1683 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1685 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1686 (xg_create_tool_bar): Adjust users.
1688 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1690 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1691 * buffer.c (Fget_buffer_create): Use it to set compact field of
1692 struct buffer_text to avoid accessing an uninitialized value
1693 when compact_buffer is called for the first time.
1694 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1695 (Fset_buffer_modified_p): Use buffer_window_count to check
1696 whether the buffer is displayed in some window.
1697 * xdisp.c (message_dolog): Likewise.
1699 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1701 * w32.c (acl_set_file): If setting the file security descriptor
1702 fails, and the new DACL is identical to the existing one, silently
1703 return success. This fixes problems for users backing up their
1704 own files without having the necessary privileges for setting
1705 security descriptors.
1707 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1709 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1710 after WaitForSingleObject returns normally. This expedites reader
1711 thread shutdown when delete_child triggers it.
1712 (reap_subprocess): More accurate commentary for why we call
1713 delete_child only when cp->fd is negative.
1715 * w32.c (sys_close): Do not call delete_child on a subprocess
1716 whose handle is not yet closed. Instead, set its file descriptor
1717 to a negative value, so that reap_subprocess will call
1718 delete_child on that subprocess when its SIGCHLD arrives.
1719 This avoids closing handles used for communications between sys_select
1720 and reader_thread, which doesn't give sys_select a chance to
1721 notice that the process exited and invoke the SIGCHLD handler for
1724 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1726 * nsfns.m (Fns_do_applescript): Run event loop until script has

1735 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1737 * w32term.c (w32fullscreen_hook): New function.
1738 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1740 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1742 * fileio.c (Finsert_file_contents): Doc fix.
1744 * w32proc.c (new_child, delete_child, find_child_pid): For a
1745 subprocess, consider its slot being in use as long as its process
1746 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1747 slot when a new process is started immediately after killing
1748 another one, without waiting enough time for the first process to
1749 be reaped and resources allocated for it be orderly freed.
1751 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1753 2012-12-21 Chong Yidong <cyd@gnu.org>
1755 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1757 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1759 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1761 * w32.c (get_name_and_id): Always pass NULL as the first argument
1762 of lookup_account_sid. Avoids crashes with UNC file names that
1763 refer to DFS domains, not to specific machine names. (Bug#12621)
1764 Remove now unused argument FNAME; all callers changed.
1765 (get_file_owner_and_group): Remove now unused argument FNAME; all
1768 2012-12-21 Chong Yidong <cyd@gnu.org>
1770 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1771 error for invalid chars, don't check for a nil return value.
1773 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1775 Avoid calls to CHAR_TO_BYTE if byte position is known.
1776 * editfns.c (make_buffer_string_both): Use move_gap_both.
1777 (Fbuffer_string): Use make_buffer_string_both.
1778 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1780 (buf_bytepos_to_charpos): Likewise.
1781 (charpos_to_bytepos): Remove.
1782 * fileio.c (Finsert_file_contents): Use move_gap_both.
1783 * search.c (Freplace_match): Likewise.
1784 * process.c (process_send_region): Likewise. Use convenient
1785 names for byte positions.
1786 * lisp.h (charpos_to_bytepos): Remove prototype.
1787 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1788 * insdel.c (move_gap): Likewise.

1796 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1797 (redisplay_internal): Don't bother selecting the frame to get the
1798 proper value of frame-local variables (bug#13225).
1800 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1802 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1803 Rename 4th argument since it may be buffer or string. Adjust comment.
1804 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1806 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1808 * coding.c (Fdetect_coding_region): Do not check start and end with
1809 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1810 (code_convert_region): Likewise.
1812 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1814 * w32.c (acl_get_file, acl_set_file): Run the file name through
1815 map_w32_filename, and resolve any symlinks in the file name, like
1817 (acl_set_file): Call revert_to_self, if any privileges were
1820 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1822 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1823 ($(BLD)/w32.$(O)): Update dependencies.
1825 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1827 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1828 propagate redisplay's scrolling (if any) to the right window.
1829 (redisplay_internal): Use ensure_selected_frame.
1830 (display_mode_lines): Complete last fix.
1831 * window.c (select_window_1): New func, extracted from select_window.
1832 (select_window): Use it.
1833 * window.h (select_window_1): Declare.
1835 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1837 Emulate Posix ACL APIs on MS-Windows.
1838 * w32.c: Include sddl.h and sys/acl.h.

1861 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1862 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1863 for some of that bug's symptoms can now cause Emacs to abort.
1864 Remove the workaround.
1865 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1866 The bug that caused SIGCHLD to get lost has been fixed, and the
1867 workaround for it can now cause Emacs to abort.
1869 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1871 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1872 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in

1877 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1878 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1879 and copy ACL entries of file in addition to SELinux context if set.
1880 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1882 * Makefile.in (LIBACL_LIBS): New macro.

1897 * w32proc.c (new_child): Initialize input_file and
1898 pending_deletion members of the child.
1899 (delete_child): Delete the child's temporary input file, if any,
1900 that is pending deletion.
1901 (register_child): First argument is now pid_t.
1902 (record_infile, record_pending_deletion): New functions.
1903 (reap_subprocess): Fix a typo in DebPrint string.
1904 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1906 * fileio.c (internal_delete_file): Return an int again: non-zero
1907 if delete-file succeeds, zero otherwise.
1909 * lisp.h (internal_delete_file): Adjust prototype.
1911 * callproc.c (Fcall_process): Don't overwrite infile with result
1913 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1914 asynchronous subprocess, record the name of the input file name,
1916 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1917 delete the file, record it as pending deletion when the subprocess
1920 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1922 * editfns.c [HAVE_PWD_H]: Include grp.h.

1932 file-ownership-preserved-p instead, with its new group arg.
1933 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1940 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1942 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1943 try to get accurate owner and group information from NT file
1944 security APIs. This is to make most callers of 'stat' and
1945 'lstat', which don't need that information, much faster.
1947 * dired.c (Ffile_attributes) [WINDOWSNT]:
1948 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1949 owner and group information from 'lstat'.
1951 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1953 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1954 as that confuses set-auto-coding, so insist on the head-read
1955 returning the full 1024 bytes. Let lseek compute the tail offset;
1956 less work for us. Do not ignore I/O errors when reading the tail.

1979 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1980 files, fixing a regression from 24.2.
1981 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1983 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1985 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1986 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1987 Remove unnecessary S_ISLNK test, as (contra the comments) this
1988 function can't copy symlinks. Improve quality of error message
1989 when attempting to copy files that are neither regular files nor

2008 * inotify.c (inotify_callback): Generate an Emacs event for every
2009 incoming inotify event.
2011 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2013 * xdisp.c (handle_face_prop): Fix logic of computing
2014 it->start_of_box_run_p.

2021 left_box_line_p and right_box_line_p flags of the glyph for R2L
2022 glyph rows. (Bug#13011)

2072 (hinst): Remove unneeded extern declaration.
2073 (_start): Remove initialization of above variables; remove

2293 * frame.c (make_frame): Do not set window's buffer to t.
2294 * window.c (Fsplit_window_internal): Likewise. Previously it was

2297 (Fset_window_buffer): ... is always true and can be removed.
2299 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2301 Convenient macro to check whether the buffer is hidden.

2330 New function, containing part of the old call_process_kill.
2331 (call_process_kill): Use it.
2332 This does not change call_process_kill's behavior.
2333 * process.c (Fdelete_process): Use record_kill_process to fix a
2334 race condition that could cause Emacs to lose track of a child.
2336 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2338 Avoid code duplication between prev_frame and next_frame.
2339 * frame.c (candidate_frame): New function. Add comment.
2340 (prev_frame, next_frame): Use it. Adjust comment.
2342 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2344 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2345 fails, signal an error instead of continuing with an empty
2347 Encode expanded temp file pattern before passing it to mkstemp or
2350 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2351 Encode the file name before passing it to dostounix_filename, in
2352 case it will downcase it (under w32-downcase-file-names).
2355 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2357 Minor call-process cleanups.
2358 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2359 at the same time as other platforms, to simplify analysis.
2360 No need for fd0_volatile since we have synch_process_fd.
2361 Avoid needless emacs_close; arg is always negative.
2363 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2365 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2368 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2370 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2371 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2372 and mouse_face_hidden members to a bitfields.
2373 * frame.h (struct frame): Remove set-but-not-used space_width member.
2374 (FRAME_SPACE_WIDTH): Remove.
2375 * nsterm.m, w32term.c, xterm.c: Adjust users.
2376 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2377 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2378 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2379 members to a bitfields.
2381 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2383 Don't let call-process be a zombie factory (Bug#12980).
2384 Fixing this bug required some cleanup of the signal-handling code.
2385 As a side effect, this change also fixes a longstanding rare race
2386 condition whereby Emacs could mistakenly kill unrelated processes,
2387 and it fixes a bug where a second C-g does not kill a recalcitrant
2388 synchronous process in GNU/Linux and similar platforms.
2389 The patch should also fix the last vestiges of Bug#9488,
2390 a bug which has mostly been fixed on the trunk by other changes.
2391 * callproc.c, process.h (synch_process_alive, synch_process_death)
2392 (synch_process_termsig, sync_process_retcode):
2393 Remove. All uses removed, to simplify analysis and so that
2394 less consing is done inside critical sections.
2395 * callproc.c (call_process_exited): Remove. All uses replaced
2396 with !synch_process_pid.
2397 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2398 These take the role of what used to be in unwind-protect arg.
2400 (block_child_signal, unblock_child_signal):
2401 New functions, to avoid races that could kill innocent-victim processes.
2402 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2403 (call_process_kill): Record killed processes as deleted, so that
2404 zombies do not clutter up the system. Do this inside a critical
2405 section, to avoid a race that would allow the clutter.
2406 (call_process_cleanup): Fix code so that the second C-g works again
2407 on common platforms such as GNU/Linux.
2408 (Fcall_process): Create the child process in a critical section,
2409 to fix a race condition. If creating an asynchronous process,
2410 record it as deleted so that zombies do not clutter up the system.
2411 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2412 light of these changes. Omit unnecessary call to emacs_close
2413 before failure, as the unwind-protect code does that.
2414 * callproc.c (call_process_cleanup):
2415 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2416 * process.c (record_deleted_pid): New function, containing
2417 code refactored out of Fdelete_process.
2418 (Fdelete_process): Use it.
2419 (process_status_retrieved): Remove. All callers changed to use
2420 child_status_change.
2421 (record_child_status_change): Remove, folding its contents into ...
2422 (handle_child_signal): ... this signal handler. Now, this
2423 function is purely a handler for SIGCHLD, and is not called after
2424 a synchronous waitpid returns; the synchronous code is moved to
2425 wait_for_termination. There is no need to worry about reaping
2426 more than one child now.
2427 * sysdep.c (get_child_status, child_status_changed): New functions.
2428 (wait_for_termination): Now takes int * status and bool
2429 interruptible arguments, too. Do not record child status change;
2430 that's now the caller's responsibility. All callers changed.
2431 Reimplement in terms of get_child_status.
2432 (wait_for_termination_1, interruptible_wait_for_termination):
2433 Remove. All callers changed to use wait_for_termination.
2434 * syswait.h: Include <stdbool.h>, for bool.
2435 (record_child_status_change, interruptible_wait_for_termination):
2437 (record_deleted_pid, child_status_changed): New decls.
2438 (wait_for_termination): Adjust to API changes noted above.
2440 * bytecode.c, lisp.h (Qbytecode): Remove.
2441 No longer needed after 2012-11-20 interactive-p changes.
2443 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2445 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2446 the scroll margin, move point outside the margin. (Bug#13055)
2448 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2450 * gtkutil.c (my_log_handler): New function.
2451 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2453 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2455 * lisp.h (modify_region): Rename to...
2456 (modify_region_1): ...new prototype.
2457 * textprop.c (modify_region): Now static. Adjust users.
2458 * insdel.c (modify_region): Rename to...
2459 (modify_region_1): ...new function to work with current buffer.
2460 Adjust comment and users. Use true and false for booleans.
2462 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2464 * alloc.c (free_save_value): New function.
2465 (safe_alloca_unwind): Use it.
2466 * lisp.h (free_save_value): New prototype.
2467 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2469 (save_excursion_restore): Adjust to match saved data structure.
2470 Use free_save_value to offload some work from GC. Drop obsolete
2473 2012-12-03 Chong Yidong <cyd@gnu.org>
2475 * fileio.c (Vauto_save_list_file_name): Doc fix.
2477 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2479 * w32fns.c: Remove prototype of atof.
2480 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2482 (file_dialog_callback): Make it UINT_PTR.
2484 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2487 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2488 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2491 2012-12-03 Glenn Morris <rgm@gnu.org>
2493 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2495 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2497 Fix xpalloc confusion after memory is exhausted.
2498 * alloc.c (xpalloc): Comment fix.
2499 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2500 and signals an error, do not clear charset_table_size, as
2501 charset_table is still valid.
2502 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2504 Use execve to avoid need to munge environ (Bug#13054).
2505 * callproc.c (Fcall_process):
2506 * process.c (create_process):
2507 Don't save and restore environ; no longer needed.
2508 * callproc.c (child_setup):
2509 Use execve, not execvp, to preserve environ.
2511 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2513 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2515 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2517 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2518 display for sliced images (Bug#10500).
2520 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2522 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2524 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2525 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2527 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2529 * xdisp.c (window_outdated): Remove eassert since it hits
2530 some suspicious corner cases (see Bug#13007 and Bug#13012).
2531 (mode_line_update_needed): New function.
2532 (redisplay_internal, redisplay_window): Use it.
2533 (ensure_selected_frame): New function.
2534 (redisplay_internal, unwind_redisplay): Use it.
2535 (redisplay_internal): Move comment about buffer_shared...
2536 (buffer_shared_and_changed): ...near to its real use.
2538 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2540 * callproc.c (Fcall_process): Don't misreport vfork failure.
2542 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2544 * callproc.c (Fcall_process): Fix vfork portability problems.
2545 Do not assume that fd[0], count, filefd, and save_environ survive
2546 vfork. Fix bug whereby wrong errno value could be reported for
2547 pipe failure. Some minor cleanups, too, as follows. Move buf and
2548 bufsize to the context where they're needed. Change new_argv to
2549 be of type char **, as this is more convenient and avoids casts.
2550 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2551 Now local constants, not macros.
2553 2012-11-18 Kenichi Handa <handa@gnu.org>
2555 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2556 for the variable "f".
2558 2012-11-13 Kenichi Handa <handa@gnu.org>
2560 * font.c (font_unparse_xlfd): Exclude special characters from the
2561 generating XLFD name.
2563 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2587 highlighting on the frame was cleared. Prevents assertion
2588 violations when repeatedly clicking on the "Top" link of the
2589 "bread-crumbs" in Info buffers.

2603 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2604 between bpos_covered and bpos_max. This fixes cursor display when
2605 several display strings follow each other.
2607 * .gdbinit (pgx): If the glyph's object is a string, display the
2608 pointer to string data, rather than the value of the string object
2609 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2611 * indent.c (Fvertical_motion): If the starting position is covered
2612 by a display string, return to one position before that, to avoid
2613 overshooting it inside move_it_to. (Bug#12930)

2626 Drop unused pending_menu_activation member.
2627 * xterm.h (struct x_output): Drop outdated #if 0 code.
2628 Use bitfields for explicit_parent, asked_for_visible,
2629 has_been_visible and net_wm_state_hidden_seen members.

2634 of a literal "/". (Bug#12955)
2635 (gl-stamp): Invoke fc.exe directly, not through cmd.

2640 * dired.c: Assume HAVE_DIRENT_H.
2641 (NAMLEN): Remove, replacing with ...
2642 (dirent_namelen): New function. All uses changed. Use the GNU macro
2643 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2644 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2645 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2646 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2648 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2649 * ndir.h: Rename to ../nt/inc/dirent.h.
2650 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2651 Do not include <dirent.h>; no longer needed.
2652 * w32.c: Include <dirent.h> rather than "ndir.h".
2654 2012-11-23 Chong Yidong <cyd@gnu.org>
2656 * xftfont.c (xftfont_open): Remove duplicate assignment.
2658 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2660 * alloc.c (Fgarbage_collect): Unblock input after clearing
2661 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2662 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2663 * msdos.c (IT_frame_up_to_date): Use it here...
2664 * w32term.c (w32_frame_up_to_date): ...here...

2706 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2708 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2710 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2711 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2712 Define for the MSVC compiler.
2714 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2716 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2717 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to

2719 dostounix_filename assumes it gets a unibyte string.
2720 Reported by Michel de Ruiter <michel@sentient.nl>, see

2769 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2771 * w32select.c: Include w32common.h before w32term.h, so that
2772 windows.h gets included before w32term.h uses some of its
2773 features, see below.
2775 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2777 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2791 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2793 * w32proc.c (waitpid): Remove unused label get_result.
2795 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2797 * makefile.w32-in (SYSWAIT_H): New macro.
2798 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2799 ($(BLD)/sysdep.$(O)): Update dependencies.
2801 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2803 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2804 * callproc.c (relocate_fd): Assume F_DUPFD.
2805 * emacs.c, term.c (O_RDWR): Remove.
2806 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2807 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2808 * nsterm.m: Assume <fcntl.h> exists.
2809 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2810 (create_pty, Fmake_network_process, server_accept_connection)
2811 (wait_reading_process_output, init_process_emacs):
2813 (wait_reading_process_output): Put in a special case for WINDOWSNT
2814 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2815 It's not clear this is needed, but it's a more-conservative change.
2816 (create_process): Assume FD_CLOEXEC.
2817 (create_process, create_pty): Assume O_NOCTTY.
2818 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2819 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2820 Omit if not DOS_NT, since F_GETFL is not defined there.
2821 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2822 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2824 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2825 lack it, since gnulib guarantees this.
2826 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2828 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2830 * w32.c (faccessat): Pretend that directories have the execute bit
2831 set. Emacs expects that, e.g., in files.el:cd-absolute.
2833 * w32proc.c (create_child): Don't clip the PID of the child
2834 process to fit into an Emacs integer, as this is no longer a
2836 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2837 reaping only the process specified by PID argument, if that is
2838 positive. Use PID instead of dead_child to know which process to
2839 reap. Wait for the child to die only if WNOHANG is not in
2841 (sys_select): Don't set dead_child.
2843 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2844 as it is no longer needed.
2846 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2848 (record_child_status_change): Remove the setting of
2849 record_at_most_one_child for the !WNOHANG case.
2851 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2853 Fix problems in ns port found by static checking.
2854 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2855 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2856 not to process group.
2857 (ns_select): Use emacs_write, not write, as that's more robust
2858 in the presence of signals.
2859 (fd_handler:): Check for read errors.
2861 2012-11-16 Glenn Morris <rgm@gnu.org>
2863 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2865 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2867 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2869 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2871 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2872 use the same value of thread handle.
2873 (start_timer_thread): If the timer thread exited (due to error),
2874 clean up by closing the two handles it used. Duplicate the caller
2875 thread's handle here, so it gets duplicated only once, when
2876 launching the timer thread. Set priority of the timer thread, not
2878 (getitimer): Don't duplicate the caller thread's handle here.
2881 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2883 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2886 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2888 Remove no-longer-used pty_max_bytes variable.
2889 * process.c (pty_max_bytes): Remove; unused.
2890 (send_process): Do not set it.
2892 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2894 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2895 Update dependencies.
2897 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2899 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2900 This follows up on the 2012-09-29 patch that removed indirection
2901 for the 'function' field. Reported by Sergey Vinokurov in
2902 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2904 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2906 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2907 different name, as the MS runtime does not have such a function,
2908 and probably never will.) All callers changed. Ignore DIRFD
2909 value if PATH is an absolute file name, to match Posix spec
2910 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2913 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2915 * xdisp.c (echo_area_display, redisplay_internal):
2916 Omit redundant check whether frame_garbaged is set.
2918 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2920 Use faccessat, not access, when checking file permissions (Bug#12632).
2921 This fixes a bug that has been present in Emacs since its creation.
2922 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2923 which must set some sort of record. (Torek's bug report was against
2924 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2925 same common flaw.) See Torek's Usenet posting
2926 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2927 Posted: Fri Apr 8 14:18:56 1983.
2928 * Makefile.in (LIB_EACCESS): New macro.
2930 * callproc.c (init_callproc):
2931 * charset.c (init_charset):
2932 * fileio.c (check_existing, check_executable, check_writable)
2934 * lread.c (openp, load_path_check):
2935 * process.c (allocate_pty):
2937 Use effective UID when checking permissions, not real UID.
2938 * callproc.c (init_callproc):
2939 * charset.c (init_charset):
2940 * lread.c (load_path_check, init_lread):
2941 Test whether directories are accessible, not merely whether they exist.
2942 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2943 * fileio.c (check_existing, check_executable, check_writable)
2945 Use symbolic names instead of integers for the flags, as they're
2947 (check_writable): New arg AMODE. All uses changed.
2948 Set errno on failure.
2949 (Ffile_readable_p): Use faccessat, not stat + open + close.
2950 (Ffile_writable_p): No need to call check_existing + check_writable.
2951 Just call check_writable and then look at errno. This saves a syscall.
2952 dir should never be nil; replace an unnecessary runtime check
2953 with an eassert. When checking the parent directory of a nonexistent
2954 file, check that the directory is searchable as well as writable, as
2955 we can't create files in unsearchable directories.
2956 (file_directory_p): New function, which uses 'stat' on most platforms
2957 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2958 (Ffile_directory_p, Fset_file_times): Use it.
2959 (file_accessible_directory_p): New function, which uses a single
2960 syscall for efficiency.
2961 (Ffile_accessible_directory_p): Use it.
2962 * xrdb.c (file_p): Use file_directory_p.
2963 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2964 * lread.c (openp): When opening a file, use fstat rather than
2965 stat, as that avoids a permissions race. When not opening a file,
2966 use file_directory_p rather than stat.
2967 (dir_warning): First arg is now a usage string, not a format.
2968 Use errno. All uses changed.
2969 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2970 that merely introduced a race.
2971 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2972 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2973 and similarly for the other O_* flags.
2974 * w32.c (sys_faccessat): Rename from sys_access and switch to
2975 faccessat's API. All uses changed.
2976 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2977 (magic_db): Rename from magic_file_p.
2978 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2979 char *, so that we don't have to test for file existence
2980 separately from opening the file for reading. This removes a race
2981 fixes a permission-checking problem, and simplifies the code.
2983 (file_p): Remove; no longer needed.
2985 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2987 Omit glyphs initialization at startup.
2988 * dispnew.c (glyphs_initialized_initially_p): Remove.
2989 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2990 (Fredraw_frame): Move actual code from here...
2991 (redraw_frame): ...to here. Add eassert. Adjust comment.
2992 (Fredraw_display): Use redraw_frame.
2993 * xdisp.c (clear_garbaged_frames): Likewise.
2995 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2997 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2998 passed to pint2str and pint2hrstr to be at most the size of the
2999 frame's decode_mode_spec_buffer. This avoids crashes with very
3000 large values of FIELD_WIDTH argument to decode_mode_spec.
3003 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3005 Fix a race with verify-visited-file-modtime (Bug#12863).
3006 Since at least 1991 Emacs has ignored an mtime difference of no
3007 more than one second, but my guess is that this was to work around
3008 file system bugs that were fixed long ago. Since the race is
3009 causing problems now, let's remove that code.
3010 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3011 whose time stamp is off by no more than a second. Insist that the
3012 file time stamps match exactly.
3014 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3016 * frame.h (struct frame): Convert external_tool_bar member to
3017 1-bit unsigned bitfield.
3018 * termhooks.h (struct terminal): Remove mouse_moved member since
3019 all users are long dead. Adjust comment on mouse_position_hook.
3021 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3023 Simplify by using FOR_EACH_FRAME here and there.
3024 * frame.c (next_frame, prev_frame, other_visible_frames)
3025 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3026 * w32term.c (x_window_to_scroll_bar): Likewise.
3027 * window.c (window_list): Likewise.
3028 * xdisp.c (x_consider_frame_title): Likewise.
3029 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3030 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3031 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3032 * xmenu.c (menubar_id_to_frame): Likewise.
3033 * xselect.c (frame_for_x_selection): Likewise.
3034 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3035 (x_window_to_menu_bar): Likewise.
3036 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3038 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3040 * data.c (Qdefalias_fset_function): Now static.
3042 Another tweak to vectorlike_header change.
3043 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3044 Remove, and replace all uses with ...
3045 (next_in_free_list, set_next_in_free_list):
3046 New functions, which respect C's aliasing rules better.
3048 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3050 * window.c (list4i): Rename from 'quad'. All uses changed.
3051 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3053 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3055 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3056 warning about mixing declarations and code in ISO C90.
3058 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3060 * window.c (Fsplit_window_internal): Set combination limit of
3061 new parent window to t iff Vwindow_combination_limit is t;
3062 fixing a regression introduced with the change from 2012-09-22.
3063 (Fset_window_combination_limit): Fix doc-string.
3065 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3067 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3068 amount when the scroll margins are too large. When scrolling
3069 backwards in the buffer, give up if cannot reach point or the
3070 scroll margin within a reasonable number of screen lines.
3071 Fixes point position in window under scroll-up/down-aggressively when
3072 point is positioned many lines beyond the window top/bottom.
3075 * ralloc.c (relinquish): If real_morecore fails to return memory
3076 to the system, don't crash; instead, leave the last heap
3077 unchanged and return. (Bug#12774)
3079 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3081 * lisp.h (AUTOLOADP): New macro.
3082 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3083 * data.c (Ffset): Remove special ad-advice-info handling.
3084 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3086 (Finteractive_form): Simplify.
3087 (Fquo): Don't insist on having at least 2 arguments.
3088 (Qdefalias_fset_function): New var.
3090 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3092 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3098 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3100 Fix recently introduced crash on MS-Windows (Bug#12839).
3101 * w32term.h (struct scroll_bar): Use convenient header.
3102 (SCROLL_BAR_VEC_SIZE): Remove.
3103 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3105 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3107 Tweak last vectorlike_header change.
3108 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3109 vectorlike object on the free list. This is introduced to avoid
3110 some (but not all) pointer casting and aliasing problems, see
3111 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3112 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3114 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3116 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3118 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3119 been removed, so remove them here also.
3121 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3123 * doc.c (Fdocumentation): Handle new property
3124 dynamic-docstring-function to replace the old ad-advice-info.
3126 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3128 * fns.c (Qeql, hashtest_eq): Now static.

3137 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3139 Use same hash function for hashfn_profiler as for hash_string etc.
3140 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3141 * lisp.h (sxhash_combine): New inline function, with the contents
3142 of the old SXHASH_COMBINE.
3143 * profiler.c (hashfn_profiler): Use it, instead of having a
3144 special hash function containing a comparison that always yields 1.
3146 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3148 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3149 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3150 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3153 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3155 * image.c (xpm_make_color_table_h): Fix compiler error because
3156 make_hash_table changed.
3158 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3160 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3162 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3164 Use ad-hoc comparison function for the profiler's hash-tables.
3165 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3166 (make_log): Use them.
3167 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3168 call Fequal any more.

3177 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3178 (hash_lookup, hash_remove_from_table): Move assertion checking of
3179 hashfn result here. Check hash-equality before calling cmpfn.

3189 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3191 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3192 value of w32-scroll-lock-modifier is neither nil nor one of the
3193 known key modifiers. (Bug#12806)
3195 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3197 Shrink struct vectorlike_header to the only size field.
3198 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3200 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3201 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3202 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3203 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3204 information from the vector header. Adjust comment.

3214 (enum mem_type): Adjust comment.
3215 (NEXT_IN_FREE_LIST): New macro.
3216 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.

3218 (struct large_vector): New type to represent allocation unit for
3219 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3220 (large_vectors): Change type to struct large_vector.
3221 (allocate_vector_from_block): Simplify.
3222 (PSEUDOVECTOR_NBYTES): Replace with...

3230 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3231 * buffer.h (struct buffer): Add next member.
3232 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3234 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3235 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3236 (copy_hash_table): Adjust to match vector header change.
3237 * lread.c (defsubr): Use XSETPVECTYPE.
3238 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3239 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3240 (xvecsize): New command.
3242 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3244 * keyboard.c (event_to_kboard): Do not dereference
3245 frame_or_window field of SELECTION_REQUEST_EVENT
3246 and SELECTION_CLEAR_EVENT events (Bug#12814).
3247 * xterm.h (struct selection_input_event): Adjust comment.
3249 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3251 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3252 such as Scroll Lock, if the respective keys are treated as
3253 function keys, not as modifiers. This avoids destroying non-ASCII
3254 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3256 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3258 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3260 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3262 Restore some duplicate definitions (Bug#12814).
3263 This undoes part of the 2012-11-03 changes. Some people build
3264 with plain -g rather than with -g3, and they need the duplicate
3265 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3266 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3267 Define as macros, as well as as enums or as constants.
3269 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3271 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3272 to keypad keys (Bug#12816).
3274 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3276 Minor adjustments of recently-changed frame functions.
3277 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3278 known to be a frame (we're in the FRAMEP branch).
3279 * lisp.h (Qframep): Remove decl. frame.h declares this.
3280 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3281 since they're meant for Lisp fixnum values.
3283 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3285 * window.c (Fwindow_combination_limit): Revert to the only
3286 required argument and adjust docstring as suggested in
3287 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3288 by Martin Rudalics <rudalics@gmx.at>.
3290 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3292 Widely used frame validity and checking functions.
3293 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3294 * frame.c (decode_live_frame, decode_any_frame): New functions.
3295 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3296 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3297 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3298 (Fframe_pointer_visible_p): Use decode_any_frame.
3299 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3300 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3301 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3302 (Fframe_focus): Likewise. Allow zero number of arguments.
3304 (frame_buffer_list, frame_buffer_predicate): Remove.
3305 * lisp.h (frame_buffer_predicate): Remove prototype.
3306 * buffer.c (Fother_buffer): Use decode_any_frame.
3307 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3308 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3309 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3310 (Fclose_font, Ffont_info): Use decode_live_frame.
3311 * fontset.c (check_fontset_name): Likewise.
3312 * terminal.c (Fframe_terminal): Likewise.
3313 * w32fns.c (check_x_frame): Likewise.
3314 * window.c (Fminibuffer_window, Fwindow_at)
3315 (Fcurrent_window_configuration): Likewise.
3316 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3317 Likewise. Allow zero number of arguments. Adjust docstring.
3318 * dispnew.c (Fredraw_frame): Likewise.
3319 * xfaces.c (frame_or_selected_frame): Remove.
3320 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3321 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3322 (Fframe_face_alist): Use decode_live_frame.
3323 * xfns.c (check_x_frame): Likewise.
3325 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3327 * window.c (quad): New function.
3328 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3329 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3330 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3331 (Fwindow_line_height): Use it.
3332 (Fwindow_fringes): Use list3.
3333 (Fwindow_scroll_bars): Use list4.
3334 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3335 (Fwindow_combination_limit): Allow zero number of arguments.
3337 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3339 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3341 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3342 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3343 file descriptor 2 for standard error. (Bug#12805)
3345 2012-11-05 Chong Yidong <cyd@gnu.org>
3347 * process.c (wait_reading_process_output): Revert previous change.
3349 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3351 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3352 This removes code that has been obsolete since around 1990.
3353 * callproc.c (Fcall_process):
3355 * process.c (create_process):
3356 * term.c (dissociate_if_controlling_tty):
3357 Assume setsid exists.
3358 * callproc.c (child_setup): Assume setpgid exists and behaves as
3359 per POSIX.1-1988 or later.
3360 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3361 * emacs.c (shut_down_emacs):
3362 * sysdep.c (sys_suspend, init_foreground_group):
3363 Assume getpgrp behaves as per POSIX.1-1998 or later.
3364 * msdos.c (setpgrp): Remove.
3365 (tcgetpgrp, setpgid, setsid): New functions.
3366 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3367 * term.c (no_controlling_tty): Remove; unused.
3368 * w32proc.c (setpgrp): Remove.
3369 (setsid, tcgetpgrp): New functions.
3371 Simplify by assuming __fpending.
3372 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3373 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3374 Do not assume that __fpending's result fits in int.
3376 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3378 Remove EMACS_OUTQSIZE+sleep hack.
3379 * dispnew.c (update_frame_1): Remove hack for terminals slower
3380 than 2400 bps, which throttled Emacs by having it sleep.
3381 This code hasn't worked since at least 2007, when the multi-tty stuff
3382 was added, and anyway those old terminals are long dead.
3383 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3384 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3386 Fix data-loss with --version (Bug#9574).
3387 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3388 as we can't assume that emacs_strerror is initialized, and strerror
3389 is good enough here.
3390 (main): Invoke atexit earlier, to catch earlier instances of
3391 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3393 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3395 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3396 (keyDown): Remap keypad keys to X11 virtual key codes.
3398 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3400 Fix data-loss with --batch (Bug#9574).
3401 * emacs.c: Include <close-stream.h>.
3402 (close_output_streams): New function.
3403 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3404 and handles errors appropriately.
3405 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3408 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3409 The symptom is a diagnostic "GLib-WARNING **: In call to
3410 g_spawn_sync(), exit status of a child process was requested but
3411 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3412 waitpid(), so exit status can't be returned." The diagnostic
3413 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3414 The real bug is a race condition between Emacs and glib: Emacs
3415 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3416 so that glib can't find it. Work around the bug by invoking
3417 waitpid only on subprocesses that Emacs itself creates.
3418 * process.c (create_process, record_child_status_change):
3419 Don't use special value -1 in pid field, as the caller now must
3420 know the pid rather than having the callee infer it.
3421 The inference was sometimes incorrect anyway, due to another race.
3422 (create_process): Set new 'alive' member if child is created.
3423 (process_status_retrieved): New function.
3424 (record_child_status_change): Use it.
3425 Accept negative 1st argument, which means to wait for the
3426 processes that Emacs already knows about. Move special-case code
3427 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3428 processes that have already been waited for, by testing and
3429 clearing new 'alive' member.
3430 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3431 now does this internally.
3432 (handle_child_signal): Let record_child_status_change do all
3433 the work, since we do not want to reap all exited child processes,
3434 only the child processes that Emacs itself created.
3435 * process.h (Lisp_Process): New boolean member 'alive'.
3437 Omit duplicate definitions no longer needed with gcc -g3.
3438 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3439 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3440 Define only as macros. There's no longer any need to also define
3441 these symbols as enums or as constants, since we now assume
3442 gcc -g3 when debugging.
3444 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3446 * lisp.mk: Adjust comments to the fact that term/internal is now
3447 loaded from loadup.el.
3449 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3450 (msdos_fatal_signal): New function.
3451 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3454 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3455 for GCC versions before 4.
3456 (emacs_raise): Define to call msdos_fatal_signal.
3458 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3459 iterator when starting in the middle of a display or overlay
3462 2012-11-03 Chong Yidong <cyd@gnu.org>
3464 * process.c (wait_reading_process_output): Clean up the last
3467 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3469 * process.c (wait_reading_process_output): Avoid a race condition
3470 with SIGIO delivery (Bug#11536).
3472 2012-11-03 Chong Yidong <cyd@gnu.org>
3474 * buffer.c (cursor_type): Untabify docstring.
3476 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3478 * frame.h (struct frame): Drop can_have_scroll_bars member
3479 which is meaningless for a long time. Adjust comments.
3480 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3481 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3483 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3485 * window.c (decode_next_window_args): Update window arg after
3486 calling decode_live_window and so fix crash reported at
3487 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3488 by Juanma Barranquero <lekktu@gmail.com>.
3489 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3490 * font.c (Ffont_at): Likewise.
3492 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3494 * widget.c (resize_cb): New function.
3495 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3496 (EmacsFrameResize): Check if all is up to date before changing frame
3499 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3501 Implement backtrace output for fatal errors on MS-Windows.
3502 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3503 (BACKTRACE_LIMIT_MAX): New macro.
3504 (w32_backtrace): New function.
3505 (emacs_abort): Use w32_backtrace when the user chooses not to
3506 attach a debugger. Update the text of the abort dialog.
3508 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3510 Window-related stuff cleanup here and there.
3511 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3512 Use decode_any_window.
3513 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3514 * xdisp.c (Fformat_mode_line): Likewise.
3515 * font.c (Ffont_at): Use decode_live_window.
3516 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3517 * window.c (decode_next_window_args): Likewise.
3518 (decode_any_window): Remove static.
3519 * window.h (decode_any_window): Add prototype.
3520 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3521 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3524 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3526 Remove pad from struct input_event.
3527 * termhooks.h (struct input_event): Remove padding field.
3529 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3530 member is never cons for a long time. Adjust comment.
3531 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3532 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3533 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3534 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3536 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3538 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3540 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3542 Fix crash when using Emacs as commit editor for git (Bug#12697).
3543 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3544 and it is configured in conf_post.h.
3545 (Fcall_process): Don't invoke both setsid and setpgid; the former
3546 is enough, if it exists.
3547 * callproc.c (Fcall_process, child_setup):
3548 * process.c (create_process): Use setpgid.
3549 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3551 * dispnew.c (init_display): Initialize the foreground group
3552 if we are running a tty display.
3553 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3554 * lisp.h (init_foreground_group): New decl.
3555 * sysdep.c (inherited_pgroup): New static var.
3556 (init_foreground_group, tcsetpgrp_without_stopping)
3557 (narrow_foreground_group, widen_foreground_group): New functions.
3558 (init_sys_modes): Narrow foreground group.
3559 (reset_sys_modes): Widen foreground group.
3561 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3563 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3565 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3567 * minibuf.c (read_minibuf): Restore current buffer since
3568 choose_minibuf_frame calling Fset_frame_selected_window may
3569 change it (Bug#12766).
3571 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3573 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3575 2012-10-30 Kenichi Handa <handa@gnu.org>
3577 * font.c (Ffont_at): If WINDOW is specified and it is not
3578 displaying the current buffer, signal an error.
3580 2012-10-29 Daniel Colascione <dancol@dancol.org>
3582 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3583 In preparation for fixing bug#12739, move these functions from
3586 * coding.h, coding.c: ... to here, and compile them only when
3587 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3588 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3590 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3592 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3593 (timer_loop, getitimer, setitimer): Use it instead of
3594 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3596 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3599 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3601 * nsterm.m (NO_APPDEFINED_DATA): New define.
3602 (last_appdefined_event_data): New variable
3603 (last_appdefined_event): Remove.
3604 (ns_select): Initialize t from last_appdefined_event_data instead
3605 of [last_appdefined_event data1].
3606 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3607 remove last_appdefined_event (Bug#12698).
3609 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3611 * frame.c (x_set_font): Catch internal error.
3613 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3615 Avoid overflow in w32 implementation of interval timers.
3616 When possible, for ITIMER_PROF count only times the main thread
3618 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3619 'volatile ULONGLONG' types. All the other data which was
3620 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3621 (GetThreadTimes_Proc): New typedef.
3622 (w32_get_timer_time): New function, returns a suitable time value
3624 (timer_loop): Enter critical section when accessing ULONGLONG
3625 values of the itimer_data struct, as these accesses are no longer
3626 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3627 Remove unused variable.
3628 (init_timers): Initialize s_pfn_Get_Thread_Times.
3629 (start_timer_thread): Don't assign itimer->caller_thread here.
3630 (getitimer): Assign itimer->caller_thread here.
3631 (setitimer): Always call getitimer to get the value of ticks_now.
3632 (sys_spawnve): Avoid compiler warning about format mismatch.
3634 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3636 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3637 mouse movement events if the menu bar is active. This avoids
3638 producing a busy "hour-glass" cursor by Windows if the mouse
3639 pointer is positioned over a tooltip shown for some menu item.
3641 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3643 Don't assume process IDs fit in int.
3644 * emacs.c (shut_down_emacs) [!DOS_NT]:
3645 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3646 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3647 Use pid_t, not int, to store process IDs, as 'int'
3648 is not wide enough on a few platforms (e.g., AIX and IRIX).
3650 2012-10-23 Kenichi Handa <handa@gnu.org>
3652 The following change is to make face-font-rescale-alist work
3653 correctly for non-ASCII fonts.
3655 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3656 (font_open_for_lface): Handle Vface_font_rescale_alist.
3658 2012-10-23 Chong Yidong <cyd@gnu.org>
3660 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3662 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3664 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3666 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3668 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3671 2012-10-21 Glenn Morris <rgm@gnu.org>
3673 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3675 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3677 Port to OpenBSD 5.1.
3678 * frame.c (Fmouse_position, Fmouse_pixel_position):
3679 * xdisp.c (produce_stretch_glyph):
3680 Declare local vars only when they're needed.
3681 This is clearer and avoids a warning on OpenBSD about unused vars.
3682 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3683 This is safer, and avoids OpenBSD warnings about unused vars.

4160 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4161 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4162 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4163 now a supported configuration.
4165 * Makefile.in: consolidate image variables into LIBIMAGE; add
4166 W32_OBJ and W32_LIBS. Compile new files.
4169 (_DebPrint) declare tracing facility for W32 debugging. We need
4170 to unify tracing later.
4172 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4173 unconditional use of W32 Unicode functions. Cygwin runs only on
4174 100% Unicode operating systems.
4176 * cygw32.c: New file. Define Cygwin-specific facilities.
4177 (Fcygwin_convert_path_to_windows)
4178 (Fcygwin_convert_path_from_windows): New user functions for
4179 accessing Cygwin path-munging routines.
4181 * cygw32.h: New file.
4182 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4183 UTF-16LE strings temporarily inside non-Lisp-visible string
4186 (w32_strerror): Just what it says on the tin.
4188 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4189 also run for Cygwin; both systems have the same problem with using
4190 GUI facilities in a forked child. Also call syms_of_cygw32,
4191 syms_of_w32select in correct places.
4193 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4194 needs fork-then-exec for daemon launching.
4196 * font.h: Include frame.h.
4198 * image.c: Use the image library cache machinery only when we're
4199 compiling for native WINDOWSNT; Cygwin can use shared libraries
4200 like any other Unixlike system.
4202 * keyboard.c: Clarify a comment regarding the input loop.
4204 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4205 functions directly instead of trying to detect at runtime that our
4206 host operating system supports them. We make this change for two
4207 reasons: Cygwin lacks support for the multibyte character
4208 conversion functions used by the legacy menu code, and Cygwin
4209 never needs to rely on non-Unicode APIs.
4211 * unexw32.c (hinst): Declare extern.
4213 * w32.c: Change header order;
4214 (w32_strerror): Move to w32fns.c because we need it for
4215 non-WINDOWSNT builds.
4217 * w32.h: Add #error macro to make sure we don't include w32.h for
4218 Cygwin builds. Remove w32select declarations.
4220 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4221 w32fns.c. w32console.c is WINDOWSNT-only.
4223 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4224 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4226 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4227 (w32_major_version, w32_minor_version, w32_build_number)
4228 (os_subtype, sound_type): Define here
4229 (w32_defined_color): Make color parameter const for consistency
4230 with other _defined_color functions.
4231 (w32_createwindow): Unconditionally call w32_init_class instead of
4232 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4233 through the code is complex and unnecessary because class
4234 registration is practically free.
4235 (w32_name_of_message): New EMACSDEBUG-only function.
4236 (Fset_message_beep): Move here
4237 (Fx_open_connection): Require that the display name for Windows be
4238 "w32" for consistency, emacsclient disambiguation, and maybe, one
4239 day, multi-window-system support.
4240 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4241 Cygwin files for W32 GUI facilities, since these clearly don't
4242 expect Cygwin names.
4243 (_DebPrint): Define.
4244 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4245 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4246 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4247 (w32_last_error): Remove.
4249 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4251 * w32heap.c (syspage_mask): Declare here.
4252 (cache_system_info): Remove.
4254 * w32inevt.c (faked_key): Define globally, not statically.
4255 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4256 (w32_console_toggle_lock_key): Move to w32fns.c.
4258 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4260 * w32proc.c (_DebPrint): Move to w32fns.c.
4261 * w32select.c: Include string.h, stdio.h for Cygwin.
4262 * w32select.h: New File.
4264 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4266 (w32_message_fd): New variable. Under Cygwin, holds the file
4267 descriptor the system used to tell us about pending thread
4270 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4271 that prevented compilation under non-WINDOWSNT systems.
4273 (w32_initialize): Open /dev/windows and assign it to
4274 w32_message_fd. Provide w32 feature.
4276 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4277 (WM_EMACS_INPUT_READY): add.
4278 (prepend_msg, w32_message_fd): Declare globally.
4281 (keyboard_handle): Use only when WINDOWSNT.
4282 (notify_msg_ready): New function. Posts a message to the main
4283 thread's message queue under CYGWIN, which wakes up the main
4284 thread from select(2) by making the /dev/windows file descriptor
4285 ready. Under WINDOWSNT, it sets an event the same way the old
4288 (post, prepend_msg): Actually call notify_msg_ready instead of
4289 setting the input event directly.
4291 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4293 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4294 but it still has blocs in it, don't return it to the system,
4295 instead of aborting. (Bug#12402)
4297 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4299 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4301 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4302 MAC_OS_X_VERSION_10_6.
4303 (syms_of_nsterm): Remove comment about Panther and above for
4305 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4306 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4307 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4309 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4310 MAC_OS_X_VERSION_10_4.
4312 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4313 MAC_OS_X_VERSION_10_2.
4315 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4317 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4318 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4320 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4321 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4322 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4323 Remove ns_in_resize check.
4324 (ns_clear_frame_area): Remove resize handle code.
4326 * nsfns.m (ns_in_resize): Remove.
4327 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4328 Remove ns_in_resize check.
4330 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4332 Improve sys_siglist detection.
4333 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4334 defined as a macro, as is done in Solaris.
4335 (sys_siglist_entries): New macro.
4336 (save_strsignal): Use it.
4337 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4338 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4340 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4342 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4343 fullscreen/Fullscreen.
4345 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4346 tobar_height is new.
4348 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4349 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4350 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4351 (windowDidResize:): Check for correct window if old style fullscreen.
4352 Capitalize word in comment. Remove incorrect comment.
4353 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4354 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4355 error in drawing background.
4356 (toggleFullScreen:): Remove comment. Rearrange calls.
4357 Set toolbar values to zero, save old height in tobar_height.
4358 Restore tool bar height when leaving fullscreen.
4359 (canBecomeMainWindow): New function.
4361 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4363 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4365 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4367 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4369 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4370 that time stamps of directories could also be changed.
4371 Don't request the too broad GENERIC_WRITE, only the more restrictive
4372 FILE_WRITE_ATTRIBUTES access rights.
4374 * fileio.c (Fset_file_times): Special-case ignoring errors for
4375 directories only on MSDOS, not on MS-Windows.
4377 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4379 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4381 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4383 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4384 see whether CreateFile failed.
4386 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4388 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4389 to avoid similar races.
4390 * keyboard.c (pending_signals): Now bool, not int.
4392 Port timers to OpenBSD, plus check for timer failures.
4393 OpenBSD problem reported by Han Boetes.
4394 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4396 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4397 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4398 like OpenBSD, which has timer_settime but does not declare it.
4399 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4400 whether to use itimerspec-related primitives. All uses of
4401 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4403 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4405 * profiler.c (handle_profiler_signal): Fix a malloc race
4406 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4408 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4410 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4412 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4414 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4415 consistent with the change in return value of 'safe_strsignal'.
4417 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4419 Prefer plain 'static' to 'static inline' (Bug#12541).
4420 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4421 (bidi_set_sor_type, bidi_push_embedding_level)
4422 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4423 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4424 (bidi_cache_search, bidi_cache_ensure_space)
4425 (bidi_cache_iterator_state, bidi_cache_find)
4426 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4427 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4428 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4429 Now 'static', not 'static inline'.
4431 Count overruns when profiling; change units to ns.
4432 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4433 Give extra weight to samples after overruns, to attempt to count
4434 the time more accurately.
4435 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4436 the underlying primitives nominally do ns.
4437 (Fprofiler_cpu_start): Document the change. Mention that
4438 the sampling intervals are only approximate.
4440 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4442 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4444 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4445 case for the special 0 coding-system.
4447 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4448 (Fmake_overlay): Remove redundant tests.
4449 (fix_start_end_in_overlays): Remove redundant recentering.
4451 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4453 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4454 Update dependencies.
4456 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4458 Fix a malloc race condition involving strsignal.
4459 A signal can arrive in the middle of a malloc, and Emacs's signal
4460 handler can invoke strsignal, which can invoke malloc, which is
4461 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4462 Fix it by altering the signal handler so that it does not invoke
4464 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4465 * process.c (status_message): Use const pointer, in case strsignal
4466 is #defined to safe_strsignal.
4467 * sysdep.c (sys_siglist, init_signals): Always define and
4468 initialize a substitute sys_siglist if the system does not define
4469 one, even if HAVE_STRSIGNAL.
4470 (safe_strsignal): Rename from strsignal. Always define,
4471 using sys_siglist. Return a const pointer.
4472 * syssignal.h (safe_strsignal): New decl.
4473 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4475 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4477 * w32proc.c (timer_loop): Fix code that waits for timer
4478 expiration, to avoid high CPU usage.
4480 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4482 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4483 (sweep_weak_table): Remove redundant prototypes.
4485 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4487 * emacs.c: Move the inclusion of TERM_HEADER after including
4488 windows.h on WINDOWSNT. This avoids compilation problems with
4491 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4493 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4494 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4495 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4496 as the previous version used 'void *'.
4498 * ralloc.c (ROUNDUP): Fix last change.
4499 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4502 * w32proc.c <disable_itimers>: New static flag.
4503 (init_timers): Initialize it to zero, after creating the critical
4504 sections used by the timer threads.
4505 (term_timers): Set to 1 before deleting the critical sections.
4506 (getitimer, setitimer): If disable_itimers is non-zero, return an
4507 error indication without doing anything. Reported by Fabrice
4508 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4509 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4511 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4514 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4515 term_ntproc after all the other bookkeeping, to get timers working
4516 as long as possible.
4518 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4520 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4521 Suggested by Juri Linkov in
4522 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4524 Prefer plain 'static' to 'static inline' (Bug#12541).
4525 With static functions, modern compilers inline pretty well by
4526 themselves; advice from programmers often hurts as much as it helps.
4527 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4528 this change shrinks the text size of the Emacs executable by 1.1%
4529 without affecting CPU significantly in my benchmark.

4615 * dired.c (directory_files_internal, Ffile_attributes):
4618 * frame.c (x_report_frame_params): Port better to wider ints.
4619 Do not assume that EMACS_UINT is the same width as uprintmax_t,

4802 Suggested by Eli Zaretskii in
4803 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.

4823 (handle_profiler_signal): Rename from sigprof_handler_1,
4824 for consistency with other handlers. Do not check whether
4825 cpu_log is a hash-table if garbage collecting, since it

4828 for consistency with other handlers.
4829 (setup_cpu_timer): New function, with much of what used to be in
4830 Fprofiler_cpu_start. Check for out-of-range argument.
4831 Prefer timer_settime if available, and prefer
4832 thread cputime clocks, then process cputime clocks, then
4833 monotonic clocks, to the old realtime clock. Use make_timeval
4834 to round more-correctly when falling back to setitimer.
4835 (Fprofiler_cpu_start): Use it.
4836 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4841 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4842 non-fatal signal handlers. Ignore SIGPROF on startup.
4843 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4844 in profiler.c, since sysdep.c now uses it.
4846 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4902 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4903 Since this stuff is now private to charset.c, there's no need for
4904 a public macro and no need to inline by hand.

4978 (sys_kill): Improve commentary.
4980 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4981 consistency with a signature of a signal handler. All callers
4983 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4984 install term_ntproc as a signal handler for SIGABRT, as that
4985 should be done by the dumped Emacs.

5064 (emacs_gnutls_handle_error):
5065 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)

5077 * nsmenu.m (ns_update_menubar):
5078 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5079 * xfns.c (Fx_show_tip) [USE_GTK]:
5080 Use bool for boolean.
5081 * gtkutil.c (xg_update_frame_menubar):
5082 * xmenu.c (update_frame_menubar):
5083 Return void, not int, since caller ignores return value.
5084 * gtkutil.c (xg_change_toolbar_position):
5087 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5089 * makefile.w32-in (BLOCKINPUT_H): Remove.

5106 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5108 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5109 fatal_error_backtrace.
5111 * w32proc.c (sys_kill): Undo last change: don't do anything when
5112 invoked to deliver SIGABRT to our own process. This is now
5113 handled by emacs_raise.
5115 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5117 * w32term.c (w32_read_socket): Remove leftover reference to
5118 interrupt_input_pending.
5120 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5122 Do not use SA_NODEFER.
5123 Problem reported by Dani Moncayo in
5124 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5126 * sysdep.c (emacs_abort): Do not reset signal handler.
5127 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5128 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5129 wanted even on POSIXish hosts, and it doesn't work on Windows.
5131 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5133 * xterm.c (x_term_init): Call fixup_locale before and after calling
5134 gtk_init (Bug#12392).
5136 2012-09-23 Chong Yidong <cyd@gnu.org>
5138 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5139 Vdynamic_library_alist.
5141 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5142 (Fgnutls_available_p): Caller changed.
5144 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5145 (Flibxml_parse_xml_region): Likewise.
5147 * dispextern.h (struct image_type): Remove arg from init function.
5149 * image.c (Finit_image_library, lookup_image_type)
5150 (define_image_type): Remove now-unneeded second arg.
5151 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5152 (init_tiff_functions, init_gif_functions, init_svg_functions):
5153 Arglist and w32_delayed_load calling convention changed.
5154 (gs_type): Remove init_gs_functions; there is no such function.
5155 (valid_image_p, make_image): Fix caller to lookup_image_type.
5157 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5159 Simplify and avoid signal-handling races (Bug#12471).
5161 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5162 Avoid recursive loop if there's a fatal error in the function itself.
5163 * atimer.c (pending_atimers):
5164 * blockinput.h: Don't include "atimer.h"; no longer needed.
5165 (interrupt_input_pending): Remove. All uses removed.
5166 pending_signals now counts both atimers and ordinary interrupts.
5167 This is less racy than having three separate pending-signal flags.
5168 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5170 Rename from their upper-case counterparts BLOCK_INPUT,
5171 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5172 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5173 This makes it easier to access volatile variables more accurately.
5174 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5175 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5176 that's more reliable if the code is buggy and sets
5177 interrupt_input_blocked to a negative value. All uses changed.
5178 * atimer.c (deliver_alarm_signal):
5179 Remove. No need to deliver this to the parent; any thread can
5180 handle this signal now. All uses replaced by underlying handler.
5181 * atimer.c (turn_on_atimers):
5182 * dispnew.c (handle_window_change_signal):
5183 * emacs.c (handle_danger_signal):
5184 * keyboard.c (kbd_buffer_get_event):
5185 Don't reestablish signal handler; not needed with sigaction.
5186 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5188 Rework to avoid unnecessary accesses to volatile variables.
5189 (UNBLOCK_INPUT_TO): Now a function.
5190 (totally_unblock_input, unblock_input): New decls.
5191 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5192 (init_data): Remove. Necessary stuff now done in init_signal.
5193 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5194 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5195 (fatal_error_code): Remove; no longer needed.
5196 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5197 it doesn't always backtrace. All uses changed. No need to reset
5198 signal to default, since sigaction and/or die does that for us now.
5199 Use emacs_raise (FOO), not kill (getpid (), FOO).
5200 (main): Check more-accurately whether we're dumping.
5201 Move fatal-error setup to sysdep.c
5202 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5203 * gtkutil.c (xg_get_file_name, xg_get_font):
5204 Remove no-longer-needed signal-mask manipulation.
5205 * keyboard.c, process.c (POLL_FOR_INPUT):
5206 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5207 * keyboard.c (read_avail_input): Remove.
5208 All uses replaced by gobble_input.
5209 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5210 (kbd_buffer_store_event_hold, gobble_input):
5211 (record_asynch_buffer_change) [USABLE_SIGIO]:
5212 (store_user_signal_events):
5213 No need to mess with signal mask.
5214 (gobble_input): If blocking input and there are terminals, simply
5215 set pending_signals to 1 and return. All hooks changed to not
5216 worry about whether input is blocked.
5217 (process_pending_signals): Clear pending_signals before processing
5218 them, in case a signal comes in while we're processing.
5219 By convention callers now test pending_signals before calling us.
5220 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5221 New functions, to support changes to blockinput.h.
5222 (handle_input_available_signal): Now extern.
5223 (reinvoke_input_signal): Remove. All uses replaced by
5225 (quit_count): Now volatile, since a signal handler uses it.
5226 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5227 All callers changed. Block SIGINT only if not already blocked.
5228 Clear sigmask reliably, even if Fsignal returns, which it can.
5229 Omit unnecessary accesses to volatile var.
5230 (quit_throw_to_read_char): No need to restore sigmask.
5231 * keyboard.c (gobble_input, handle_user_signal):
5232 * process.c (wait_reading_process_output):
5233 Call signal-handling code rather than killing ourselves.
5234 * lisp.h: Include <float.h>, for...
5235 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5236 (pending_signals): Now volatile.
5237 (syms_of_data): Now const if IEEE floating point.
5238 (handle_input_available_signal) [USABLE_SIGIO]:
5239 (terminate_due_to_signal, record_child_status_change): New decls.
5240 * process.c (create_process): Avoid disaster if memory is exhausted
5241 while we're processing a vfork, by tightening the critical section
5243 (send_process_frame, process_sent_to, handle_pipe_signal)
5244 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5246 (send_process): No need for setjmp/longjmp any more, since the
5247 SIGPIPE stuff is now gone. Instead, report an error if errno
5249 (record_child_status_change): Now extern. PID and W are now args.
5250 Return void, not bool. All callers changed.
5251 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5252 Remove. All uses removed. This bug should be fixed now in a
5254 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5255 and record the child status change directly. This avoids the
5256 need to futz with the signal mask.
5257 (process_fatal_action): Move here from emacs.c.
5258 (emacs_sigaction_flags): New function, containing
5259 much of what used to be in emacs_sigaction_init.
5260 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5261 caught by emacs, to make races less likely.
5262 (deliver_process_signal): Rename from handle_on_main_thread.
5264 (BACKTRACE_LIMIT_MAX): Now at top level.
5265 (thread_backtrace_buffer, threadback_backtrace_pointers):
5267 (deliver_thread_signal, deliver_fatal_thread_signal):
5268 New functions, for more-accurate delivery of thread-specific signals.
5269 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5270 (deliver_arith_signal): Handle in this thread, not
5271 in the main thread, since it's triggered by this thread.
5272 (maybe_fatal_sig): New function.
5273 (init_signals): New arg DUMPING so that we can be more accurate
5274 about whether we're dumping. Caller changed.
5275 Treat thread-specific signals differently from process-general signals.
5276 Block all signals while handling fatal error; that's safer.
5277 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5279 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5280 Ignore SIGPIPE unless batch.
5281 (emacs_backtrace): Output backtrace for the appropriate thread,
5282 which is not necessarily the main thread.
5283 * syssignal.h: Include <stdbool.h>.
5284 (emacs_raise): New macro.
5285 * xterm.c (x_connection_signal): Remove; no longer needed
5286 now that we use sigaction.
5287 (x_connection_closed): No need to mess with sigmask now.
5288 (x_initialize): No need to reset SIGPIPE handler here, since
5289 init_signals does this for us now.
5291 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5293 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5294 background rect may be larger (Bug#12245).
5296 2012-09-23 Chong Yidong <cyd@gnu.org>
5298 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5300 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5302 * .gdbinit: Just stop at fatal_error_backtrace.
5303 See Stefan Monnier's request in
5304 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5305 Remove no-longer-used query of system type.
5307 2012-09-22 Chong Yidong <cyd@gnu.org>
5309 * search.c (Freplace_match): Doc fix (Bug#12325).
5311 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5313 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5314 (Fline_end_position): Doc fix.
5316 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5318 2012-09-22 Chong Yidong <cyd@gnu.org>
5320 * dispextern.h (struct image_type): Add new slot, storing a type
5321 initialization function.
5323 * image.c (define_image_type): Call the image initializer function
5324 if it is defined. Arguments and return value changed.
5325 (valid_image_p, make_image): Callers changed.
5326 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5327 (gif_type, imagemagick_type, svg_type, gs_type):
5328 Add initialization functions.
5329 (Finit_image_library): Call lookup_image_type.
5330 (CHECK_LIB_AVAILABLE): Macro deleted.
5331 (lookup_image_type): Call define_image_type here, rather than via
5332 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5333 (syms_of_image): Move define_image_type calls for xbm_type and
5334 pbm_type to lookup_image_type.
5336 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5338 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5339 'idle_timers' from here ...
5340 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5341 lists, to avoid infloops when the timer does something stupid,
5342 like reinvoke itself with the same or smaller time-out.
5345 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5347 * window.c (Fsplit_window_internal): Handle only Qt value of
5348 Vwindow_combination_limit separately.
5349 (Qtemp_buffer_resize): New symbol.
5350 (Vwindow_combination_limit): New default value.
5353 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5355 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5356 the new overlay string. (Bug#10159)
5358 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5360 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5361 or that fprintf is async-signal-safe. POSIX doesn't require
5364 2012-09-22 Chong Yidong <cyd@gnu.org>
5366 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5369 2012-09-22 Kenichi Handa <handa@gnu.org>
5371 * composite.c (composition_reseat_it): Handle the case that a
5372 grapheme cluster is not covered by a single font (Bug#12352).
5374 2012-09-21 Chong Yidong <cyd@gnu.org>
5376 * image.c (define_image_type): Avoid adding duplicate types to
5377 image_types (Bug#12463). Suggested by Jörg Walter.
5379 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5381 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5382 (print_load_command_name): Add case LC_DATA_IN_CODE.
5383 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5385 2012-09-21 Glenn Morris <rgm@gnu.org>
5387 * eval.c (Frun_hook_with_args_until_success)
5388 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5390 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5392 * fileio.c (Ffile_selinux_context): Only call freecon when
5393 lgetfilecon succeeded.
5394 (Fset_file_selinux_context): Likewise. (Bug#12444)
5396 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5398 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5399 reordering, locate the cursor by calling set_cursor_from_row; if
5400 that fails, clear the desired glyph matrix before returning a
5401 failure indication to the caller. Fixes leaving garbled display
5402 when fast scrolling with a down-key. (Bug#12403)
5403 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5404 scrolling through multibyte text.
5406 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5408 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5409 calling mark_vectorlike since that's the one that marks the window.
5410 (mark_discard_killed_buffers): Mark the final cdr.
5411 * window.h (struct window): Move prev/next_buffers to the
5412 non-standard fields.
5413 * window.c (make_window): Initialize prev/next_buffers manually.
5415 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5417 Omit unused arg EXPECTED from socket hooks.
5418 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5419 * nsterm.m (ns_term_init):
5420 * termhooks.h (struct terminal.read_socket_hook):
5421 * w32inevt.c (w32_console_read_socket):
5422 * w32term.c (w32_read_socket):
5423 * xterm.c (XTread_socket):
5424 Omit unused arg EXPECTED. All callers changed.
5425 (store_user_signal_events): Return void, not int, since callers no
5426 longer care about the return value. All uses changed.
5428 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5430 * w32gui.h (XParseGeometry): Do not declare.
5432 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5434 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5435 Ignore 'expected'. See Eli Zaretskii in
5436 <http://bugs.gnu.org/12471#8> (last line).
5438 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5439 (XParseGeometry): Now static. Substitute extremal values for
5440 values that are out of range.
5442 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5444 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5446 * nsfns.m (XParseGeometry): Remove.
5447 (Fx_create_frame): Call x_set_offset to correctly interpret
5448 top_pos in geometry.
5450 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5451 (Fx_parse_geometry): If there is a space in string, call
5452 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5454 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5456 * search.c (scan_buffer): Use character positions in calls to
5457 region_cache_forward and region_cache_backward, not byte
5458 positions. (Bug#12196)
5460 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5461 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5463 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5464 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5465 emacs_blocked_malloc, now deleted.
5467 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5469 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5470 The workaround was for improving performance on Solaris 2.4, but
5471 is getting in the way now. Emacs will still work if someone is
5472 still running Solaris 2.4 in a museum somewhere; Sun dropped
5473 support for Solaris 2.4 in 2003.
5474 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5475 * process.c (create_process) [HAVE_WORKING_VFORK]:
5476 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5477 since Emacs no longer uses vfork on that platform.
5479 2012-09-17 Glenn Morris <rgm@gnu.org>
5481 * emacs.c: Use COPYRIGHT.
5483 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5485 Remove configure's --without-sync-input option (Bug#12450).
5486 When auditing signal-handling in preparation for cleaning it up,
5487 I found that SYNC_INPUT has race conditions and would be a real
5488 pain to fix. Since it's an undocumented and deprecated
5489 configure-time option, now seems like a good time to remove it.
5490 Also see <http://bugs.gnu.org/11080#16>.
5491 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5492 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5493 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5494 (malloc_hysteresis):
5495 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5496 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5497 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5498 (dont_register_blocks, bytes_used_when_reconsidered)
5499 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5500 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5501 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5502 Remove. All uses removed.
5503 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5504 implementation, one that depends on whether the new macro
5505 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5507 * atimer.c (run_timers, handle_alarm_signal):
5508 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5509 (handle_async_input, process_pending_signals)
5510 (handle_input_available_signal, init_keyboard):
5511 * nsterm.m (ns_read_socket):
5512 * process.c (wait_reading_process_output):
5513 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5514 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5516 * xterm.c (XTread_socket):
5518 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5519 * eval.c (handling_signal): Remove. All uses removed.
5520 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5521 All uses replaced with the SYNC_INPUT version.
5522 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5524 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5527 * font.c (Ffont_shape_gstring): Remove unused local.
5529 2012-09-16 Glenn Morris <rgm@gnu.org>
5531 * Makefile.in (clean): No longer run nextstep's clean.
5533 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5535 (ns-app): Move here from ns.mk, and simplify.
5536 (clean): Simplify nextstep entry.
5537 * ns.mk: Remove file.
5539 2012-09-17 Kenichi Handa <handa@gnu.org>
5541 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5542 not covert the last few charactes.
5544 2012-09-16 Kenichi Handa <handa@gnu.org>
5546 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5547 here, but just check the validity of glyphs in the glyph-string.
5549 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5551 * window.c (Fwindow_parameter, Fset_window_parameter):
5552 Accept any window as argument (Bug#12452).
5554 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5556 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5557 to ns_term_init to avoid memory leak.
5559 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5560 explicit retain/release.
5561 (ns_term_init): Only allow one display. Initialize outerpool and
5564 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5566 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5567 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5568 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5569 the Microsoft problem in a different way, by altering ../nt/config.nt.
5571 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5586 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5587 by lisp.h. This completes removal of setjmp.h inclusion
5588 erroneously announced in the previous commit. (Bug#12446)
5590 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5593 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5594 not defined as a macro. The latter happens on MS-Windows.
5597 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5599 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5600 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5601 Some instances of '#include <setjmp.h>' removed, if the
5602 only reason for the instance was because "lisp.h" was included.
5603 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5604 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5605 and _longjmp with the new symbols. Emacs already uses _setjmp if
5606 available, so this change affects only POSIXish hosts that have
5607 sigsetjmp but not _setjmp, such as some versions of Solaris and
5608 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5609 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5610 (png_load_body) [HAVE_PNG]:
5611 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5612 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5613 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5614 since PNG requires jmp_buf. This is the only exception to the
5615 general rule that we now use sys_setjmp and sys_longjmp.
5616 This exception is OK since this code does not change the signal
5617 mask or longjmp out of a signal handler.
5619 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5621 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5622 Include "syssignal.h", for 'main_thread'.
5624 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5626 Avoid out-of-range marker position (Bug#12426).
5627 * insdel.c (replace_range, replace_range_2):
5628 Adjust markers before overlays, as suggested by comments.
5629 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5630 Remove redundant check before calling offset_intervals.
5632 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5634 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5635 current buffer (Bug#12387).
5637 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5639 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5641 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5643 Use a more backwards-compatible timer format (Bug#12430).
5644 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5645 vector element, not from the 4th, since PSECS is now at the end.
5646 (Fcurrent_idle_time): Doc fix.
5648 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5650 Function to mark objects and remove killed buffers at once.
5651 * alloc.c (discard_killed_buffers): Rename to ...
5652 (mark_discard_killed buffers) ... new name. Add marking
5653 of remaining objects. Fix comment. Adjust users.
5654 (mark_object): Do not touch frame buffer lists here.
5655 * frame.c (delete_frame): Reset frame buffer lists here.
5657 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5659 Better workaround for GNOME bug when --enable-gcc-warnings.
5660 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5661 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5662 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5664 Simplify SIGIO usage (Bug#12408).
5665 The code that dealt with SIGIO was crufty and confusing, e.g., it
5666 played tricks like "#undef SIGIO" but these tricks were not used
5667 consistently. Simplify mostly by not #undeffing standard symbols,
5668 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5669 or not as we please) rather than "defined SIGIO" (standard symbol
5670 that we probably shouldn't #undef).
5671 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5672 Modules that need it can include it.
5673 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5674 * dispextern.h (ignore_sigio): New decl.
5675 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5676 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5677 * emacs.c (shut_down_emacs):
5678 * keyboard.c (kbd_buffer_store_event_hold):
5679 Use ignore_sigio rather than invoking 'signal' directly.
5680 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5682 (FIONREAD, SIGIO): Do not #undef.
5683 (tty_read_avail_input): Use #error rather than a syntax error.
5684 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5685 for I_PIPE, used by SETUP_SLAVE_PTY.
5686 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5687 * sysdep.c (croak): Remove; no longer needed. This bit of
5688 temporary code, with Fred N. Fish's comment that it's temporary,
5689 has been in Emacs since at least 1992!
5690 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5691 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5692 * syssignal.h (croak): Remove decl.
5693 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5694 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5695 now that we're termios-only.
5696 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5697 * term.c (dissociate_if_controlling_tty): Use #error rather than
5700 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5701 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5702 to work around GNOME bug 683906.
5703 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5704 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5705 This works around GCC bug 54561.
5707 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5709 More fixes for 'volatile' and setjmp/longjmp.
5710 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5711 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5712 (png_load_body) [HAVE_PNG]:
5713 (jpeg_load_body) [HAVE_JPEG]:
5714 New function, with most of the old parent function's body.
5715 (png_load) [HAVE_PNG]:
5716 (jpeg_load) [HAVE_JPEG]:
5717 Invoke the new function, to avoid longjmp munging our locals.
5718 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5719 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5720 longjmp is passed 2, as the C standard doesn't guarantee this.
5721 Instead, store the failure code into mgr->failure_code.
5723 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5725 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5726 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5727 (syms_of_keyboard): Remove support for unread-command-char.
5729 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5731 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5732 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5733 violation. (Bug#12426)
5735 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5737 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5739 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5741 * eval.c: Add `inhibit-debugger'.
5742 (Qinhibit_debugger): New symbol.
5743 (call_debugger): Bind it instead of Qdebug_on_error.
5744 (maybe_call_debugger): Test Vinhibit_debugger.
5745 (syms_of_eval): Define inhibit-debugger.
5746 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5747 (syms_of_xdisp): Remove inhibit-debug-on-message.
5749 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5751 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5752 If a nonvolatile local variable is written before a _longjmp to
5753 the frame containing the variable, and is read after the _longjmp,
5754 the value read is indeterminate. Some local variables of type
5755 'struct handler' and 'struct catchtag' are used in this way, so
5756 mark each of their slots as volatile if the slot can be set before
5757 _longjmp and read afterwards.
5758 * lisp.h (struct handler): var and chosen_clause are now volatile.
5759 (struct catchtag): val, next, and pdlcount are now volatile.
5761 * bidi.c (bidi_push_it, bidi_pop_it):
5762 * fns.c (copy_hash_table):
5763 * image.c (define_image_type):
5764 * keyboard.c (kbd_buffer_store_event_hold):
5765 * process.c (Fprocess_send_eof):
5766 * xfaces.c (x_create_gc) [HAVE_NS]:
5767 * xgselect.c (xg_select):
5768 Prefer assignment to memcpy when either will do.
5770 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5771 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5772 time an item is removed. No need to mark this function 'inline';
5773 the compiler knows better than we do.
5775 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5777 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5778 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5779 to change_frame_size (Bug#12388).
5780 (windowDidResize:): Pass YES to updateFrameSize.
5782 * nsterm.h: Add delay parameter to updateFrameSize.
5784 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5786 Discard killed buffers from deleted window and frame objects.
5787 This reduces an amount of references to killed buffers and
5788 helps GC to reclaim them faster.
5789 * alloc.c (discard_killed_buffers): New function.
5790 (mark_object): Use it for deleted windows and frames.
5791 (mark_object): If symbol's value is set up for a killed buffer
5792 or deleted frame, restore its global binding.
5793 * data.c (swap_in_global_binding): Add GC notice.
5794 (swap_in_symval_forwarding): Use convenient set_blv_where.
5795 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5796 * window.h: ... to here.
5798 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5800 Convenient macro to check whether the buffer is live.
5801 * buffer.h (BUFFER_LIVE_P): New macro.
5802 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5803 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5805 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5807 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5808 composition cases (Bug#12364).
5810 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5811 overhang of succeeding glyphs overlapping box cursor.
5813 * w32term.c (x_draw_glyph_string): Likewise.
5815 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5817 Simplify, document, and port floating-point (Bug#12381).
5818 The porting part of this patch fixes bugs on non-IEEE platforms
5819 with frexp, ldexp, logb.
5820 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5822 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5823 support, by removing commented-out code and briefly listing the
5824 C89 functions excluded. The commented-out stuff was confusing
5825 maintenance, e.g., we thought we needed cbrt but it was commented out.
5826 (logb): Remove decl; no longer needed.
5827 (isfinite): New macro, if not already supplied.
5828 (isnan): Don't replace any existing macro.
5829 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5830 are present on all C89 platforms.
5831 (Ffrexp): Do not special-case zero, as frexp does the right thing
5833 (Flogb): Do not use logb, as it doesn't have the desired meaning
5834 on hosts that use non-base-2 floating point. Instead, stick with
5835 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5836 frexp, to avoid getting an unspecified result.
5838 * xdisp.c (Qinhibit_debug_on_message): Now static.
5840 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5842 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5843 NSBezierPath (Bug#12131).
5845 2012-09-10 Chong Yidong <cyd@gnu.org>
5847 * fns.c (Fdelq, Fdelete): Doc fix.
5849 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5851 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5852 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5854 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5856 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5857 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5860 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5862 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5863 left fringe if the window has a left margin. This avoids leaving
5864 traces of the cursor because its leftmost pixel is not drawn over.
5866 * dispnew.c (update_window_line): When the left margin area of a
5867 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5868 that screen line. (Bug#12277)
5870 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5872 Assume C89 or later for math functions (Bug#12381).
5873 This simplifies the code, and makes it a bit smaller and faster,
5874 and (most important) makes it easier to clean up signal handling
5875 since we can stop worring about floating-point exceptions in
5876 library code. That was a problem before C89, but the problem
5877 went away many years ago on all practical Emacs targets.
5878 * data.c, image.c, lread.c, print.c:
5879 Don't include <math.h>; no longer needed.
5880 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5881 might be autoconfigured, as that never happens.
5883 * doprnt.c (DBL_MAX_10_EXP):
5884 * print.c (DBL_DIG):
5885 Remove. C89 or later always defines these.
5886 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5887 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5888 (arith_error, domain_error, domain_error2):
5889 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5890 no longer needed -- we simply return what C returns. All uses removed.
5891 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5893 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5894 Remove. All uses expanded, as these macros are no longer used
5895 more than once and are now more trouble than they're worth.
5896 (Ftan): Use tan, not sin / cos.
5897 (Flogb): Assume C89 frexp.
5898 (fmod_float): Assume C89 fmod.
5899 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5900 (init_floatfns): Remove. All uses removed.
5902 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5904 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5905 compositeToPoint for OSX < 10.6 (Bug#12390).
5907 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5909 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5910 This produces more-accurate results.
5912 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5914 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5915 changes (Bug#12088).
5917 2012-09-08 Chong Yidong <cyd@gnu.org>
5919 * syntax.c (Fstring_to_syntax): Doc fix.
5921 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5923 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5924 in the internal border.
5925 (x_set_window_size): Remove static variables and their usage.
5926 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5927 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5928 Remove fringe/internal border adjustment (Bug#11052).
5929 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5930 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5931 (ns_fix_rect_ibw): Remove.
5932 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5933 (ns_dumpglyphs_box_or_relief): Ditto.
5934 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5936 (ns_dumpglyphs_image): Ditto.
5937 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5939 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5940 their usage. Add fringe_extended_p and its use as in other terms.
5941 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5942 scroll bar was removed.
5943 (updateFrameSize): New function.
5944 (windowDidResize): Move code to updateFrameSize and call it.
5946 * nsterm.h (EmacsView): Add updateFrameSize.
5948 2012-09-07 Chong Yidong <cyd@gnu.org>
5950 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5952 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5954 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5956 More signal-handler cleanup (Bug#12327).
5957 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5958 Problem introduced when merging patches. Noted by Eli Zaretskii in
5959 <http://bugs.gnu.org/12327#67>.
5960 * floatfns.c: Comment fix.
5961 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5962 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5963 and anyway the declaration is harmless even if SIGDANGER is not defined.
5964 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5965 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5966 source files not surprisingly expected syssignal.h to define, or
5967 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5968 Include <sys/ioctl.h>, for FIONREAD.
5969 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5970 This eliminates a problem whereby other files mysteriously had
5971 to include "syssignal.h" before including "systty.h" if they
5972 wanted to use "#ifdef SIGIO".
5974 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5976 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5978 * w32.c (sigemptyset): Empty the set.
5979 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5981 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5983 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5985 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5986 (mark_object): Likewise for frame objects.
5988 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5990 * syssignal.h (handle_on_main_thread): Always declare,
5991 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5992 This ports to platforms without HAVE_PTHREAD.
5994 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5996 Signal-handler cleanup (Bug#12327).
5997 Emacs's signal handlers were written in the old 4.2BSD style with
5998 sigblock and sigmask and so forth, and this led to some
5999 inefficiencies and confusion. Rewrite these to use
6000 pthread_sigmask etc. without copying signal sets around. Also,
6001 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6002 'signal', and instead use functions that do not attempt to take
6003 over the system name space. This patch causes Emacs's text
6004 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6005 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6006 Do not include <signal.h> or "syssignal.h", as these
6007 modules do not use signals.
6008 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6009 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6010 Do not include <signal.h>, as "syssignal.h" does that for us now.
6011 * atimer.c (sigmask_atimers): New function.
6012 (block_atimers, unblock_atimers): New functions,
6013 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6015 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6016 no longer needed here.
6017 * emacs.c (main): Inspect existing signal handler with sigaction,
6018 so that there's no need to block and unblock SIGHUP.
6019 * sysdep.c (struct save_signal): New member 'action', replacing
6020 old member 'handler'.
6021 (save_signal_handlers, restore_signal_handlers):
6022 Use sigaction instead of 'signal' to save and restore.
6023 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6024 New function. All users of 'signal' modified to use set_sighandler
6025 if they're writeonly, and to use sys_signal if they're read+write.
6026 (emacs_sigaction_init, forwarded_signal): New functions.
6027 (sys_signal): Remove. All uses replaced by calls to sigaction
6028 and emacs_sigaction_init, or by direct calls to 'signal'.
6029 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6030 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6031 all uses replaced by pthread_sigmask etc. calls.
6032 * syssignal.h: Include <signal.h>.
6033 (emacs_sigaction_init, forwarded_signal): New decls.
6034 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6035 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6036 (sigmask, sys_sigmask): Remove; no longer needed.
6037 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6038 (sigblock, sigunblock, sigfree):
6039 (sigsetmask) [!defined sigsetmask]:
6040 Remove. All uses replaced by pthread_sigmask.
6041 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6042 no longer need to be replaced, and its typical old uses
6043 are now done via emacs_sigaction_init and sigaction.
6044 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6045 (sys_sigdel): Remove; unused.
6046 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6048 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6050 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6051 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6053 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6055 Explicitly mark buffer_defaults and buffer_local_symbols.
6056 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6057 mark_local_symbols here.
6058 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6059 since special buffers aren't marked here any more.
6060 (allocate_buffer): Chain new buffer with all_buffers here...
6061 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6063 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6064 (syms_of_buffer): Remove staticpro of the above.
6065 (init_buffer_once): Set names for buffer_defaults and
6066 buffer_local_symbols.
6068 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6070 Use bool for booleans in font-related modules.
6071 * font.c (font_intern_prop, font_style_to_value)
6072 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6073 (generate_otf_features, font_check_otf_features, font_check_otf)
6074 (font_match_p, font_list_entities, font_at):
6075 * fontset.c (fontset_id_valid_p, reorder_font_vector
6076 (fontset_find_font, Fset_fontset_font)
6077 (face_suitable_for_char_p) [0]:
6078 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6079 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6080 (m17n_flt_initialized, ftfont_shape_by_flt):
6081 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6082 * nsfont.m (nsfont_draw):
6083 * w32font.c (w32font_draw):
6084 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6085 Use bool for booleans.
6086 * font.h: Adjust to above API changes.
6087 (struct font, struct font_driver, struct font_driver_list):
6088 Use bool for booleans.
6089 (struct font): Remove useless member encoding_type.
6091 * fontset.c, xftfont.c: Omit unnecessary static decls.
6093 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6095 * alloc.c (mark_object): Revert window marking code
6096 since it's unsafe for the Fset_window_configuration.
6098 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6100 Fix race conditions with signal handlers and errno (Bug#12327).
6101 Be more systematic about preserving errno whenever a signal
6102 handler returns, even if it's not in the main thread. Do this by
6103 renaming signal handlers to distinguish between signal delivery
6104 and signal handling. All uses changed.
6105 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6106 * data.c (deliver_arith_signal): Rename from arith_error.
6107 * dispnew.c (deliver_window_change_signal): Rename from
6108 window_change_signal.
6109 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6110 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6111 * keyboard.c (deliver_input_available_signal): Rename from
6112 input_available_signal.
6113 (deliver_user_signal): Rename from handle_user_signal.
6114 (deliver_interrupt_signal): Rename from interrupt_signal.
6115 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6116 (deliver_child_signal): Rename from sigchld_handler.
6117 * atimer.c (handle_alarm_signal):
6118 * data.c (handle_arith_signal):
6119 * dispnew.c (handle_window_change_signal):
6120 * emacs.c (handle_fatal_signal, handle_danger_signal):
6121 * keyboard.c (handle_input_available_signal):
6122 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6123 * process.c (handle_pipe_signal, handle_child_signal):
6124 New functions, with the actual signal-handling code taken from the
6125 original respective signal handlers, sans the sporadic attempts to
6126 preserve errno, since that's now done by handle_on_main_thread.
6127 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6128 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6129 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6131 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6132 Move initialization of main_thread to sysdep.c's init_signals.
6133 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6134 our usage, and simplifies the mainline code.
6135 (record_child_status_change): New static function, as a helper
6136 for handle_child_signal, and with most of the old child handler's
6138 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6139 (handle_child_signal): Use the above.
6140 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6141 Moved here from emacs.c.
6142 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6143 code moved here from emacs.c's main function.
6144 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6145 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6146 This lets callers save and restore errno properly.
6148 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6150 Remove redundant or unused things here and there.
6151 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6152 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6153 * editfns.c (Fcompare_buffer_substrings): Likewise.
6154 * frame.h (struct terminal, struct font_driver_list):
6155 Remove redundant declarations.
6156 * window.h (Qleft, Qright): Likewise.
6158 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6160 Do not mark objects from deleted buffers, windows and frames.
6161 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6162 (mark_object): Likewise for windows and frames.
6164 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6166 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6167 buffer_defaults and buffer_local_symbols as valid objects.
6168 Return special value to denote them.
6170 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6172 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6173 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6174 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6175 (file_name_absolute_p, Fsubstitute_in_file_name):
6176 (check_executable, check_writable, Ffile_accessible_directory_p)
6177 (Fset_file_selinux_context, Fdefault_file_modes)
6178 (Finsert_file_contents, choose_write_coding_system)
6179 (Fwrite_region, build_annotations, a_write, e_write)
6181 * filelock.c (boot_time_initialized, get_boot_time)
6182 (get_boot_time_1, lock_file_1, within_one_second):
6183 * floatfns.c (in_float):
6184 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6185 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6186 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6187 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6188 * window.c (compare_window_configurations):
6189 Use bool for booleans.
6190 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6191 (Fdefault_file_modes): Now mode_t, not int, for modes.
6192 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6193 (internal_delete_file): Now returns void, not a (boolean) int,
6194 since nobody was looking at the return value.
6195 * lisp.h, window.h: Adjust to above API changes.
6197 * xdisp.c (set_message): Simplify and reindent last change.
6199 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6201 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6203 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6205 * eval.c (call_debugger): Make the function non-static so that we
6206 can call it from set_message.
6208 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6209 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6211 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6213 Give more-useful info on a fatal error (Bug#12328).
6214 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6215 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6216 of doing the work ourselves.
6217 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6218 do most of the work.
6219 (fatal_error_backtrace): New function, taken from the guts
6220 of the old fatal_error_signal, but with a new option to output
6222 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6223 info about the signal than just its number.
6224 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6225 * sysdep.c: Include <execinfo.h>
6226 (emacs_backtrace): New function, taken partly from the previous
6227 code of the 'die' function.
6228 (emacs_abort): Call fatal_error_backtrace rather than abort.
6230 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6232 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6233 eager (load-time) macro-expansion.
6234 * lisp.mk (lisp): Add macroexp.
6236 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6238 Simplify redefinition of 'abort' (Bug#12316).
6239 Do not try to redefine the 'abort' function. Instead, redo
6240 the code so that it calls 'emacs_abort' rather than 'abort'.
6241 This removes the need for the NO_ABORT configure-time macro
6242 and makes it easier to change the abort code to do a backtrace.
6243 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6244 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6245 Remove; sysdep.c's emacs_abort now takes its place.
6246 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6247 'abort' changed to use 'emacs_abort'.
6248 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6249 (abort) [!defined abort]: Rename to ...
6250 (emacs_abort): ... new name.
6251 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6252 the place of the old 'abort' in emacs.c.
6253 * w32.c, w32fns.c (abort): Do not #undef.
6254 * w32.c (emacs_abort): Rename from w32_abort.
6256 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6258 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6259 offsets[j].dv, since the y axis of the screen coordinates points
6260 down, while the y axis of the font definition coordinates points
6261 up. This fixes display of Arabic diacritics such as KASRA and
6262 KASRATAN. (Bug#11860)
6264 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6266 Be more systematic about _setjmp vs setjmp.
6267 * alloc.c (test_setjmp, mark_stack):
6268 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6269 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6270 (png_load, my_error_exit, jpeg_load):
6271 * process.c (send_process_trap, send_process):
6272 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6273 The underscored versions are up to 30x faster on some hosts.
6274 Formerly, the code used setjmp+longjmp sometimes and
6275 _setjmp+_longjmp at other times, with no particular reason to
6276 prefer setjmp+longjmp.
6278 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6280 Fix minor problem found by static checking.
6281 * buffer.c (Fdelete_all_overlays): Return nil.
6283 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6285 * buffer.c (Fdelete_all_overlays): New function.
6287 2012-09-03 Chong Yidong <cyd@gnu.org>
6289 * gtkutil.c: Add extern decl for Qxft.
6291 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6293 * emacs.c, eval.c: Use bool for boolean.
6294 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6295 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6296 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6297 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6298 (main, decode_env_path, Fdaemon_initialized):
6299 * eval.c (call_debugger, Finteractive_p, interactive_p):
6300 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6301 (maybe_call_debugger, Fbacktrace):
6302 * process.c (read_process_output, exec_sentinel):
6303 Use bool for booleans.
6304 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6305 All callers changed.
6306 * eval.c (interactive_p): Omit always-true boolean argument
6307 EXCLUDE_SUBRS_P. All callers changed.
6308 * dispextern.h, lisp.h: Reflect above API changes.
6309 * firstfile.c (dummy): Use the address of 'main', whose signature
6310 won't change, instead of the address of 'initialize', whose
6311 signature just changed from int to bool.
6312 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6313 * msdos.c (fatal_error_in_progress): ... from here.
6314 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6316 (redisplay_internal, unwind_redisplay): Simply clear
6317 REDISPLAYING_P when unwinding, instead of saving its previous,
6318 always-false value and then restoring it.
6320 Clean up some extern decls.
6321 Mostly, this hoists extern decls out of .c files and into .h files.
6322 That way, we're more likely to catch errors if the interfaces change.
6323 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6324 declare xg_mark_data.
6325 * dispextern.h (x_frame_parm_handlers):
6327 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6328 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6329 (Qultra_bold, Qoblique, Qitalic):
6330 Move extern decl here from .c file.
6331 * alloc.c (xg_mark_data) [USE_GTK]:
6333 * eval.c (Qlexical_binding):
6334 * fns.c (time) [!HAVE_UNISTD_H]:
6335 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6336 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
6337 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
6338 * lread.c (Qinternal_interpreter_environment):
6339 * minibuf.c (Qbuffer):
6340 * process.c (QCfamily, QCfilter):
6341 * widget.c (free_frame_faces):
6342 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6343 * xfont.c (x_clear_errors):
6344 * xterm.c (x_frame_parm_handlers):
6345 Remove now-redundant extern decls.
6346 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6347 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6349 * xfaces.c: Remove unnecessary static decls.
6350 * xterm.c (updating_frame): Remove decl of nonexistent object.
6352 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6353 when building globals.h, as the objects that are not built on
6354 this host are not needed to compile C files on this host.
6356 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6358 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
6360 * frame.h: Add missing prototype for x_wm_set_size_hint.
6362 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6364 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.
6365 * doc.c (read_bytecode_char, get_doc_string, reread_doc_file)
6366 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6367 (Fsubstitute_command_keys):
6368 * editfns.c (region_limit, find_field, Fconstrain_to_field)
6369 (save_excursion_save, save_excursion_restore)

6408 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6409 more than one grapheme cluster passed to the shaper: compute the
6410 offset adjustment values separately for each cluster. (Bug#11860)
6412 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6413 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6414 about implicit conversions from integer to pointer.

6472 window system declarations.
6474 * frame.h: Move common functions here: set_frame_menubar,
6475 x_set_window_size, x_sync, x_get_focus_frame,
6476 x_set_mouse_position, x_set_mouse_pixel_position,
6477 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6508 * term.c (mark_ttys): Remove.
6509 (init_tty): Safely initialize 'top_frame' slot with Qnil.

6533 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6534 for GCC 4.7.1 x86-64.
6536 2012-08-30 Glenn Morris <rgm@gnu.org>
6538 * lread.c (init_lread): For out-of-tree builds, only add the
6539 source directory's site-lisp dir to the load-path if it exists,
6540 consistent with in-tree builds. (Bug#12302)
6542 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6773 are all boolean, so make them single-bit bitfields.
6775 * lisp.h (ASET): Remove attempt to detect side effects.
6776 It was meant to be temporary and it often doesn't work,
6777 because when IDX has side effects the behavior of IDX==IDX
6778 is undefined. See Stefan Monnier in
6779 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

6790 as that's faster and simpler than static storage. Don't bother
6791 with the g_main_context_query overhead if g_main_context_pending
6792 says no events are pending.
6793 (gfds, gfds_size): Remove these static vars.
6794 (xgselect_initialize): Remove; no longer needed.
6795 All uses and decls removed.

6822 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6823 (getenv_internal, sync_process_alive, call_process_exited):
6824 * lisp.h (USE_SAFE_ALLOCA):
6825 Use bool for booleans, instead of int.
6826 * lisp.h, process.h: Adjust prototypes to match above changes.
6827 * callint.c (Fcall_interactively): Don't assume the mark's
6828 offset fits in 'int'.
6830 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6832 * buffer.c, buffer.h: Use bool for boolean.
6833 * buffer.c (reset_buffer_local_variables)
6834 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6835 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6836 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6837 (overlay_touches_p, overlay_strings, Foverlay_put)
6838 (report_overlay_modification, call_overlay_mod_hooks):
6839 (mmap_enlarge, mmap_set_vars):
6840 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6841 Use bool for booleans, instead of int.
6842 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6843 since the 1-or-0 return value is always ignored anyway.
6844 (mmap_initialized_p):
6845 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6846 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6848 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6850 * bidi.c: Use bool for boolean.
6851 This is a bit more readable, and makes the text segment of bidi.o
6852 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6853 Presumably it's faster too.
6854 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6856 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6857 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6858 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6859 (bidi_explicit_dir_char, bidi_level_of_next_char)
6860 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6861 Use bool for booleans, instead of int.
6862 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6863 (bidi_unshelve_cache): Adjust decls to match code.
6865 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6867 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6870 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6872 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6873 * atimer.h: Include <stdbool.h>.
6875 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6877 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6878 compile time tests instead of run time tests on systems that do
6880 (FRAME_MAC_P): Remove leftover from deleted code.
6881 * frame.c (syms_of_frame): Remove leftover from deleted code.
6883 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6885 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6887 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6889 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6890 Otherwise, the compiler complains about (A?B:C) where B is void
6891 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6892 (fontset_add): Return void, for FONTSET_ADD.
6894 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6896 * alloc.c: Use bool for booleans.
6897 (gc_in_progress, abort_on_gc)
6898 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6899 (dont_register_blocks) [GC_MALLOC_CHECK]:
6900 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6901 (check_string_bytes, make_specified_string, memory_full)
6902 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6903 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6904 (mark_stack, valid_pointer_p, make_pure_string)
6905 (Fgarbage_collect, survives_gc_p, gc_sweep):
6906 Use bool for booleans, instead of int.
6907 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6908 Remove unused local.
6909 * alloc.c (PURE_POINTER_P):
6910 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6911 * editfns.c (Fformat):
6912 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6914 * fns.c (sweep_weak_table):
6915 * lisp.h (suppress_checking, push_message, survives_gc_p)
6916 (make_pure_string, gc_in_progress, abort_on_gc):
6917 * lread.c (readchar, read1):
6918 * print.c (Fprin1_to_string):
6919 * xdisp.c (push_message):
6920 Use bool for booleans affected directly or indirectly by
6923 Make recently-introduced setters macros.
6924 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6925 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6926 (set_fontset_default, set_fontset_fallback): Rename from their
6927 upper-case counterparts, and make them functions rather than macros.
6928 This is more consistent with the other recently-introduced setters.
6929 These don't need to be inline, since they're local.
6931 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6933 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6934 the loop (Bug#12247).
6936 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6938 * lisp.h (vcopy): Use memcpy rather than our own loop.
6939 This fixes a performance regression introduced by the recent
6940 addition of vcopy. This means 'vcopy' will need to be modified
6941 for a copying collector, but that's OK. Also, tighten the
6942 checking in the assertion.
6944 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6946 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6947 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6948 non-base glyph for the width of the base character, according to
6949 what x_draw_composite_glyph_string_foreground expects.
6950 Generate WADJUST value according to composition_gstring_width's
6951 expectations, to produce correct width of the composed character.
6952 Reverse the sign of the DU offset produced by ScriptPlace.
6954 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6956 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6958 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6960 Avoid direct writes to contents member of struct Lisp_Vector.
6961 * lisp.h (vcopy): New function to copy data into vector.
6962 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6963 * fns.c (Ffillarray): Use ASET.
6964 * keyboard.c (timer_check_2): Use AREF and ASET.
6965 (append_tool_bar_item, Frecent_keys): Use vcopy.
6966 * lread.c (read_vector): Use ASET.
6967 * msdos.c (Frecent_doskeys): Use vcopy.
6968 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6969 (Finternal_merge_in_global_face): Use ASET and vcopy.
6970 * xfont.c (xfont_list_pattern): Likewise.
6972 2012-08-21 Martin Rudalics <rudalics@gmx.at>

6975 the position of its buffer's point.
6976 (Fset_window_point): For the selected window always go in its
6977 buffer to the specified position.
6979 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6981 Setter macros for fontsets.
6982 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6983 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6984 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6987 2012-08-20 Glenn Morris <rgm@gnu.org>
6989 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6990 Don't assume that `ln -f' works.
6992 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6994 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6995 and later about non-assignments with no effect. See discussion at
6996 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6999 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7001 Inline setter functions for Lisp_Objects slots of struct specbinding.
7002 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7005 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7007 * window.c (select_window): Always make selected window's buffer
7010 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7012 Use AREF and ASET for docstrings of category tables.
7013 * category.h (CATEGORY_DOCSTRING): Use AREF.
7014 (SET_CATEGORY_DOCSTRING): Use ASET.
7015 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7017 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7019 Inline setter functions for hash table members.
7020 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7021 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7022 (set_hash_key_and_value, set_hash_index, set_hash_next)
7023 (set_hash_hash): New functions.
7024 * charset.c, fns.c: Adjust users.
7026 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7028 Inline getter and setter functions for per-buffer values.
7029 * buffer.h (per_buffer_default, set_per_buffer_default)
7030 (per_buffer_value, set_per_buffer_value): New functions.
7031 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7032 * buffer.c, data.c: Adjust users.
7034 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7036 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7038 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7040 Rely on <config.h> + <unistd.h> to declare 'environ',
7041 as gnulib does this if the system doesn't.
7042 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7043 Remove declaration. MS-Windows declares it on stdlib.h which is
7044 included by conf_post.h.
7045 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7046 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7047 * vm-limit.c: Include <unistd.h>, for 'environ'.
7049 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7050 (start_of_data): Remove decl; mem-limits.h provides it.
7052 * xdisp.c (handle_invisible_prop): Make it a bit faster
7053 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7055 2012-08-19 Chong Yidong <cyd@gnu.org>
7057 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7060 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7062 * .gdbinit: Use call instead of set when calling a function in the
7065 * data.c (set_internal): Don't use set_blv_found.
7066 (Fkill_local_variable): Likewise.
7068 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7070 * nsfont.m (ns_ascii_average_width): Ensure the string
7071 ascii_printable is initialized with a null-terminated character
7072 array. Otherwise, it can contain undesired extra characters.
7074 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7076 port new setting code to Sun C 5.8 2005/10/13
7077 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7078 Return void, not Lisp_Object. Otherwise, the compiler
7079 complains about (A?B:C) where B is void and C is Lisp_Object
7080 when compiling CHAR_TABLE_SET, due to the recent change to
7081 the API of sub_char_table_set_contents.
7083 2012-08-18 Chong Yidong <cyd@gnu.org>
7085 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7086 for the string case (Bug#3874).
7088 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7090 * buffer.h (BSET): Remove (Bug#12215).

7169 are compiled into code.
7170 (tset_param_alist): New setter function.
7172 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
7174 * keyboard.h (KSET): Remove (Bug#12215).

7203 Define to EXTERN_INLINE, so that the corresponding functions
7204 are compiled into code.
7205 (fset_buffer_predicate, fset_minibuffer_window): New setter functions.
7207 A few more naming-convention fixes for getters and setters.
7208 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,
7209 and rename from buffer_overlays_set_before.
7210 (set_buffer_overlays_after): Move here from buffer.h, and rename
7211 from buffer_overlays_set_after.
7212 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

7215 * intervals.c (set_interval_object): Move here from intervals.h,
7216 and rename from interval_set_object.
7217 (set_interval_left): Move here from intervals.h, and rename from
7219 (set_interval_right): Move here from intervals.h, and rename from
7221 (copy_interval_parent): Move here from intervals.h, and rename from
7222 interval_copy_parent.
7223 * intervals.h (set_interval_parent): Rename from interval_set_parent.
7224 (set_interval_plist): Rename from interval_set_plist.

7239 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
7240 "set_char_table_parent (char_table, parent);".

7913 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7914 * w32.c (init_environment): Change the default values of many
7915 environment variables in dflt_envvars[] to NULL, to avoid pushing
7916 them into environment when they were not already defined.
7917 Remove the code that deletes site-lisp subdirectories from the default
7918 value of EMACSLOADPATH, as it is no longer needed.
7919 (check_windows_init_file): Now external, not static.
7920 Use Vload_path as is, without adding anything, as this function is now
7921 called when Vload_path is already set up.
7923 * w32.h (check_windows_init_file): Add prototype.
7925 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7932 installation tree, as appropriate.
7934 * callproc.c (init_callproc_1): Call decode_env_path instead of
7935 doing its equivalent by hand.
7936 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
7937 the code that sets Vexec_path run on MS-Windows.
7939 * lread.c (init_lread): Add comments to #ifdef's.
7941 * msdos.c (dos_set_window_size, IT_update_begin)

7953 Remove unnecessary casts involving pointers.
7954 These casts are no longer needed now that we assume C89 or later,

7968 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7969 Remove unnecessary pointer casts.
7970 * alloc.c (record_xmalloc): New function.
7971 * lisp.h (record_xmalloc): New decl.
7972 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7973 more like a function. This is because the pointer cast is not
7974 needed. All uses changed.
7975 * print.c (print_string, print_error_message): Avoid length recalc.
7977 Improve fix for macroexp crash with debugging (Bug#12118).
7978 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7979 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7980 not supposed to be invoked from the garbage collector.

7982 (gc_aset): New function, which is like ASET but can be
7983 used in the garbage collector.

8012 with addition of handling of symlinks and support for 'lstat'.
8013 If possible, get file's attributes and security information by
8014 handle, not by name. Produce S_IFLNK bit for symlinks, when
8015 called from 'lstat'.
8016 (stat, lstat): New functions, call 'stat_worker'.
8017 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8018 symlinks when the underlying filesystem supports them.
8020 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8022 Fix macroexp crash on Windows with debugging (Bug#12118).
8023 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8024 checking subscripts; problem introduced with the recent
8025 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8026 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8027 since it's used in non-static inline functions now.
8029 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8030 Don't assume buffer size fits in 'int'. Remove unused local.

8050 * composite.c (COMPOSITE_INLINE):
8051 * dispnew.c (DISPEXTERN_INLINE):
8052 * sysdep.c (SYSTIME_INLINE):
8053 Define to EXTERN_INLINE, so that the corresponding functions
8054 are compiled into code.
8055 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8056 (INLINE_HEADER_END): New macros.
8057 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8077 hard-coding the path separator.
8079 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8081 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8082 This how ASET and AREF are supposed to work, and makes
8083 it easier to think about future improvements. See
8084 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8085 * charset.h (set_charset_attr): New function.

8577 the fix for 12036 would have avoided some of the problems noted in

8579 would have been more obvious.
8580 * emacs.c: Do not include <verify.h>; no longer needed.
8581 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8582 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8583 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8584 Remove; now done in lisp.h.
8585 * lisp.h (PUBLISH_TO_GDB): New macro.

8589 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8590 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8591 not be usable in #if. This simplifies things.
8593 2012-07-26 Juanma Barranquero <lekktu@gmail.com>

8600 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8601 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8602 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8603 Adjust to changes in lisp.h and emacs.c, by using
8604 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8605 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8606 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8607 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8608 instead of gdb_valbits.
8609 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8610 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8611 instead of gdb_array_mark_flag.
8612 (xboolvector): Get size from $->size, not $->header.size.
8613 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8614 (xreload, hook-run, hookpost-run): Remove.
8615 * emacs.c: Include <verify.h>.
8616 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

8619 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8620 (gdb_USE_LSB_TAG): New enum constants.
8621 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8623 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8624 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8625 as constants, so they're visible to GDB.

8627 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8628 Now enum constants, not macros, so they're visible to GDB.
8629 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8630 more convenient now. All uses changed.
8631 (VALMASK) [USE_LSB_TAG]: Also define in this case.

8644 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8646 Use typedef for EMACS_INT, EMACS_UINT.
8647 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8648 than macros. This simplifies debugging in the usual case, since
8649 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8650 and it allows expressions involving EMACS_INT casts.
8651 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8653 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8669 (init_buffer_once): Initialize indirection counters of
8670 buffer_defaults and buffer_local_symbols (for sanity and safety).
8672 2012-07-24 Eli Zaretskii <eliz@gnu.org>

8705 Swap buffer text indirection counters in Fbuffer_swap_text.
8706 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8707 This avoids crash reported by Christoph Scholtes at
8708 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8710 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8712 * nsmenu.m (Popdown_data): New struct.

8735 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8737 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8738 as it's limited by the amount of memory, not by INT_MAX.
8740 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8742 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

8893 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8895 * eval.c (Fdefvar): Don't check constants since we only set the var if
8896 it's not yet defined anyway (bug#11904).

8899 * keyboard.c (command_loop_1): Set it.
8900 * cmds.c (Fself_insert_command): Use it to only remove boundaries that

9485 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9486 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9487 not functions. All uses rewritten to use the following, respectively:

9489 (add_emacs_time, sub_emacs_time): New functions.
9490 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9516 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9517 * nsterm.m (ns_term_init):
9518 Avoid the need for strncpy, by using build_string or
9519 make_unibyte_string directly. Use dtoastr, not snprintf.
9520 * process.c (Fmake_network_process): Diagnose service names that
9521 are too long, rather than silently truncating them or creating
9522 non-null-terminated names.
9523 (Fnetwork_interface_info): Likewise, for interface names.
9524 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9525 Prefer sprintf to strncat.
9526 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

9537 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9538 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9539 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

9552 Optimize pure C strings initialization.
9553 * lisp.h (make_pure_string): Fix prototype.
9554 (build_pure_c_string): New function, defined as static inline. This
9555 provides a better opportunity to optimize away calls to strlen when
9556 the function is called with compile-time constant argument.
9557 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9558 argument, adjust users accordingly. Use build_pure_c_string where
9560 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9561 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9562 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9564 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9566 Avoid calls to strlen in miscellaneous functions.
9567 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9568 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.

9573 Avoid calls to strlen in path processing functions.
9574 * fileio.c (file_name_as_directory): Add comment. Change to add
9575 srclen argument and return the length of result. Adjust users

9579 Adjust users accordingly.
9580 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9582 2012-07-10 Glenn Morris <rgm@gnu.org>

9589 * s/gnu.h (DATA_START): Move definitions to configure.
9591 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9592 We include usg5-4-common.h, which defines them both.
9594 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9595 O_RDONLY already includes it).
9597 Stop ns builds setting the EMACSLOADPATH environment variable.
9598 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9599 Now it does not set EMACSLOADPATH, just returns the load-path string.
9600 * nsterm.h: Update accordingly.
9601 * lread.c [HAVE_NS]: Include nsterm.h.
9602 (init_lread) [HAVE_NS]: Use ns_load_path.

9605 2012-07-09 Glenn Morris <rgm@gnu.org>
9607 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9608 since the included bsd-common.h does so.
9610 Stop ns builds setting the EMACSPATH environment variable.
9611 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9612 (ns_init_paths): Do not set EMACSPATH.
9613 * nsterm.h (ns_exec_path): Add it.
9614 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9617 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9619 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9621 * process.c (wait_reading_process_output): 'waitchannels' was unset
9622 when read_kbd || !NILP (wait_for_cell); fix this.
9624 Add GCC-style 'const' attribute to functions that can use it.
9625 * character.h (char_resolve_modifier_mask):
9626 * keyboard.h (make_ctrl_char):
9627 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9636 Add decls with ATTRIBUTE_CONST.
9638 Minor improvements to make_formatted_string.
9639 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9640 where int is good enough, as vsprintf returns an int.
9641 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9643 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9645 Use make_formatted_string to avoid double length calculation.
9646 * lisp.h (make_formatted_string): New prototype.

9670 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9672 Move marker debugging code under MARKER_DEBUG.
9673 * marker.c (MARKER_DEBUG): Move marker debugging code under
9674 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9675 for bootstrap with --enable-checking (~3x slowdown reported
9676 by Juanma Barranquero <lekktu@gmail.com>).
9677 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9679 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9681 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9682 See <http://bugs.gnu.org/11825#29>.
9684 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9686 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9687 has no font, use the frame's font. (Bug#11813)
9688 (display_line): Add commentary about displaying truncation glyphs
9690 (produce_special_glyphs): Move here from term.c.
9692 * term.c (produce_special_glyphs): Move to xdisp.c.
9694 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9697 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9699 * xdisp.c (display_line): Avoid warning about implicit declaration
9702 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9704 * lisp.h: Remove empty conditional.
9706 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9708 * lread.c (load_path_check): Now static.
9710 Fix some minor --with-ns problems found by static checking.
9711 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9712 (x_set_font) [!HAVE_X_WINDOWS]:
9713 * image.c (xpm_load_image) [HAVE_NS]:
9714 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9715 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9716 Remove unused local.
9717 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9718 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9719 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9720 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9721 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9722 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9723 Fix pointer signedness problem.
9724 * xfaces.c (FRAME_X_FONT_TABLE):
9725 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9727 2012-07-07 Glenn Morris <rgm@gnu.org>
9729 * lread.c (load_path_check): New function, split from init_lread.
9730 (init_lread): Reorganize. Motivation:
9731 If EMACSLOADPATH is set, check/warn about that rather than the
9732 defaults, which we are not going to use. Hence we can remove
9733 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9734 Don't warn if site-lisp directories are missing.
9735 If not installed, start from a blank load-path, since
9736 PATH_LOADSEARCH refers to the eventual installation directories.
9738 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9740 Support truncation and continuation glyphs on GUI frames, when
9741 fringes are disabled. (Bug#11832)
9742 * xdisp.c (init_iterator): Get dimensions of truncation and
9743 continuation glyphs even if on GUI frames.
9744 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9745 or both, are absent.
9746 (start_display, move_it_in_display_line_to): Handle the case of a
9747 GUI frame without a fringe to display continuation or truncation
9749 (insert_left_trunc_glyphs): Support GUI frames: make sure
9750 truncation glyphs overwrite enough glyphs from the current line to
9751 have sufficient space in pixels.
9752 (display_line): Support truncation and continuation glyphs on GUI
9753 frames. If some spare pixels are left on the line after inserting
9754 the truncation glyphs, fill that space with a stretch glyph of a
9755 suitably computed width.
9757 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9758 produce_glyphs, to support GUI sessions.
9760 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9762 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9764 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9766 Do not require float-time's arg to fit in time_t (Bug#11825).
9767 This works better on hosts where time_t is unsigned, and where
9768 float-time is applied to the (negative) difference between two times.
9769 * editfns.c (decode_time_components): Last arg is now double *,
9770 not int *, and means to store all the result as a double, without
9771 worrying about whether the seconds part fits in time_t.
9772 All callers changed.
9773 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9774 All callers changed.
9775 (Ffloat_time): Do not fail merely because the specified time falls
9776 outside of time_t range.
9778 2012-07-07 Glenn Morris <rgm@gnu.org>
9780 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9781 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

9784 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9786 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9787 Update dependencies.
9789 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9791 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9793 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

9795 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9796 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9797 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9798 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9800 * xfont.c (compare_font_names): Redo to omit the need for casts.
9802 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9804 * xfns.c (Fx_change_window_property): Doc fix.
9805 * w32fns.c (Fx_change_window_property): Doc fix.
9807 * w32fns.c (Fx_window_property): Accept the same arguments as the
9808 X Windows version. Doc fix.
9809 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9811 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9812 Eli Zaretskii <eliz@gnu.org>
9814 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9815 Windows-specific code from nt/config.nt moved here.
9816 Obsolete settings removed.
9818 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9820 * process.c: Avoid unnecessary calls to gettime.
9821 (wait_reading_process_output): Don't get the time of day
9822 when gobbling data immediately and not waiting, as there's no need
9823 for it in that case. This removes a FIXME.
9825 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9827 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9828 is defined (Bug#11768).
9830 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9832 Fix marker debugging code.
9833 * marker.c (byte_char_debug_check): Do not perform the check
9834 if buffer is not multibyte.
9835 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9836 Call byte_char_debug_check with correct arguments.
9838 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9840 Compile marker debugging code only if ENABLE_CHECKING is defined.
9841 * marker.c (byte_char_debug_check, count_markers):
9842 Use only if ENABLE_CHECKING is defined.
9843 (byte_debug_flag): Remove.
9844 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9845 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9847 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9849 Avoid code repetition in marker-related functions.
9850 * marker.c (attach_marker): New function.
9851 (Fset_marker, set_marker_restricted, set_marker_both)
9852 (set_marker_restricted_both): Use it.
9853 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9854 Consistently rename charno to charpos.
9855 (marker_position): Add eassert.
9856 (marker_byte_position): Convert to eassert.

9875 * window.c (save_window_save): Likewise.
9877 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9879 Do not use Fdelete_overlay in delete_all_overlays
9880 to avoid redundant calls to unchain_overlay.
9881 * buffer.c (drop_overlay): New function.
9882 (delete_all_overlays, Fdelete_overlay): Use it.
9883 * minibuf.c (get_minibuffer): Fix comment.
9885 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9887 Port to OpenBSD 5.1 amd64.
9888 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9889 This is needed for OpenBSD, and should be harmless on all BSD systems.
9890 Also, include <sys/sysctl.h>, as it should be available on all
9891 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9892 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9893 use p_pid member, not kp_proc.pid.
9895 2012-07-06 Glenn Morris <rgm@gnu.org>
9897 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9899 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9901 More xmalloc and related cleanup.

9910 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9912 Omit needless casts involving void * pointers and allocation.
9913 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9914 as the former is more robust if P's type is changed.
9915 Prefer xzalloc to xmalloc + memset 0.
9916 Simplify malloc-or-realloc to realloc.
9917 Don't worry about xmalloc returning a null pointer.
9918 Prefer xstrdup to xmalloc + strcpy.
9919 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9921 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9922 alloca of a constant.
9924 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9926 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9927 hscroll is larger than the line width. Fixes long and futile
9928 looping inside extend_face_to_end_of_line (on a TTY) producing
9929 glyphs that are not needed and thrown away.
9931 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9933 * marker.c (set_marker_restricted_both): Simplify by using

9947 followed by gtk_box_set_homogeneous (Bug#11768).
9948 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9949 (update_theme_scrollbar_width, xg_create_scroll_bar):
9950 Use gtk_scrollbar_new (Bug#11768).
9951 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9952 (is_box_type): New function (Bug#11768).
9953 (xg_tool_item_stale_p): Call is_box_type.
9954 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9955 with default display (Bug#11768).

10027 * fileio.c (time_error_value): Check the right error number.
10028 Problem reported by Troels Nielsen in
10029 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10031 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10033 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10034 This should be fixed in a better way; see Eli Zaretskii in
10035 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10036 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10038 * fileio.c (time_error_value): Rename from special_mtime.
10039 The old name's problems were noted by Eli Zaretskii in
10040 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10042 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10043 This variable's comment says Emacs needs at least one GDB-visible
10044 symbol of type enum pvec_type, to work around GDB problems.
10045 The symbol's value doesn't matter.
10047 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10048 that causes compilation to fail on pre-C99 compilers.
10050 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10052 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10053 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10055 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10057 * buffer.c (init_buffer_once): Fix initialization of
10058 headers for buffer_defaults and buffer_local_symbols.
10059 Reported by Juanma Barranquero <lekktu@gmail.com>.
10061 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10063 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10064 * lisp.h (enum pvec_type): Use fewer bits.
10065 (PSEUDOVECTOR_SIZE_BITS): New constant.
10066 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10067 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10068 change in pvec_type.
10069 (PSEUDOVECTOR_TYPEP): New macro.
10070 (TYPED_PSEUDOVECTORP): Use it.
10071 * fns.c (internal_equal): Adapt code to extract pvectype.
10072 * emacs.c (gdb_pvec_type): Update type.
10073 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10074 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10075 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10076 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10077 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10078 abusing vector->header.next.nbytes.
10079 (live_vector_p): Use PVEC_TYPE.
10080 (mark_object): Adapt code to extract pvectype. Use switch.
10082 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10084 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10085 Tighten new eassert a bit.
10087 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10089 Fix compilation with --enable-gcc-warnings and -O1
10090 optimization level.
10091 * doprnt.c (doprnt): Change type of tem to int, initialize
10092 to avoid compiler warning. Add eassert.
10093 * search.c (simple_search): Initialize match_byte to avoid
10094 compiler warning. Add eassert.
10096 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10098 Avoid weird behavior with large horizontal scrolls.
10099 Without this change, for example, large hscroll values would
10100 mess up Emacs's display on Fedora 15 x86, presumably due to
10101 overflows in int calculations in the display code.
10102 Also, if buffers had long lines, Emacs would freeze.
10103 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10104 (set_window_hscroll): New function, containing the old guts of
10105 Fset_window_hscroll. Return the clipped value.
10106 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10107 This avoids the need to check against PTRDIFF_MAX.
10109 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10111 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10113 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10115 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10117 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10118 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10119 since GCC 4.4.6 issues a bogus warning for them.
10121 Fix bugs in file timestamp newness comparisons.
10122 * fileio.c (Ffile_newer_than_file_p):
10123 * lread.c (Fload): Use full timestamp resolution of files,
10124 not just the 1-second resolution, so that files that are only
10125 slightly newer still count as newer.
10126 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10127 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10129 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10131 * fileio.c: Improve handling of file time marker. (Bug#11852)
10132 (special_mtime): New function.
10133 (Finsert_file_contents, Fverify_visited_file_modtime):
10134 Use it to set special mtime values consistently.
10136 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10138 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10139 marker for non-existing file. (Bug#11852)
10141 2012-07-03 Glenn Morris <rgm@gnu.org>
10143 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10144 and did not make it into globals.h).
10146 2012-07-03 Tom Tromey <tromey@redhat.com>
10148 * window.c (Fset_window_margins, Fset_window_fringes)
10149 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

10175 * font.h: Remove EXFUNs.
10176 * dosfns.c (system_process_attributes): Remove EXFUN.
10177 * keymap.h: Remove EXFUNs.

10179 * w32term.h: Remove EXFUNs.

10182 * xterm.h: Remove EXFUN.
10184 2012-07-03 Glenn Morris <rgm@gnu.org>
10186 * lisp.h (Frandom): Make it visible to C.
10187 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10188 buffer for invisible buffers. (Bug#1229)
10190 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10192 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10193 values which aren't power of 2.
10194 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10195 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10198 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10200 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10202 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10204 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10206 * alloc.c (allocate_vector_block): Remove redundant
10207 calls to mallopt if DOUG_LEA_MALLOC is defined.
10208 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10209 avoid calls to mallopt if zero_vector is returned.
10211 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10213 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10214 is enabled, avoid dereferencing NULL current_sblock if
10217 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10219 Cleanup basic buffer management.
10220 * buffer.h (struct buffer): Change layout to use generic vector
10221 marking code. Fix some comments. Change type of 'clip_changed'
10222 to bitfield. Remove unused #ifndef old.
10223 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10224 (GET_OVERLAYS_AT): Fix indentation.
10225 (for_each_per_buffer_object_at): New macro.
10226 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

10230 struct buffer. Fix comment.
10231 (mark_overlay): New function.

10234 (mark_object): Use it. Adjust marking of misc objects
10235 and related comments.
10237 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10239 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10240 wrapper that is not needed because the wrapped code is a no-op (zero
10241 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10242 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10244 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10246 * alloc.c (mark_buffer): Simplify. Remove prototype.
10247 (mark_object): Add comment. Reorganize marking of vector-like
10248 objects. Use CHECK_LIVE for all vector-like objects except buffers
10249 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10250 Avoid redundant calls to mark_vectorlike for bool vectors.
10252 2012-06-30 Glenn Morris <rgm@gnu.org>
10254 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10256 * epaths.in (PATH_SITELOADSEARCH): New.
10257 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10258 This is rather than relying on --enable-locallisppath elements
10259 having "site-lisp" in their names. (Bug#10208#25, 11658)
10261 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10263 * w32proc.c (sys_select): Accept and ignore one more argument.
10265 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10267 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10268 (pselect) [!MS_DOS]: Redirect to sys_select.
10270 * sysdep.c: Don't include dos.h and dosfns.h.
10272 * process.c (sys_select):
10273 * msdos.c (sys_select): Accept one more argument and ignore it.
10275 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10276 adapt data types and code to that.
10279 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10280 which clashes with the gnulib function of the same name.
10282 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10284 * font.c (font_style_to_value, font_style_symbolic)
10285 (font_prop_validate_style): Add type checks for values in
10288 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10290 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10293 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10295 * xdisp.c (try_window_id): Undo last change.
10297 * w32.c (getwd): Adjust commentary about startup_dir.
10298 (init_environment): Always call sys_access, even in non-MSVC
10299 builds. Don't chdir to the directory of the Emacs executable.
10300 This undoes code from 1997 which was justified by the need to
10301 "avoid conflicts when removing and renaming directories". But its
10302 downside was that every relative file name was being interpreted
10303 relative to the directory of the Emacs executable, which can never
10304 be TRT. In particular, it broke sys_access when called with
10305 relative file names.
10306 (sys_access): Map GetLastError to errno.
10308 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10310 * window.h (struct window): Change type of 'fringes_outside_margins'
10311 to bitfield. Fix comment. Adjust users accordingly.

10314 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10317 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10319 * gnutls.c (emacs_gnutls_handshake):
10320 Add QUIT to make the loop interruptible.
10322 2012-06-29 Glenn Morris <rgm@gnu.org>
10324 * charset.c (init_charset): Make lack of etc/charsets fatal.
10326 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10328 * editfns.c (region_limit): Fix type mismatch.
10330 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10332 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10333 undefined. Convert from xassert to eassert.
10334 * nsmenu.m: Convert from xassert to eassert.
10335 * nsterm.m: Likewise.
10337 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10339 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10341 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10343 Avoid integer overflow on scroll-left and scroll-right.
10344 * window.c (HSCROLL_MAX): New macro.
10345 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10346 overflow when requested scroll falls outside ptrdiff_t range.
10348 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10350 * window.h (struct window): Change type of 'hscroll',
10351 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10352 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10353 Adjust users accordingly.
10354 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10355 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10356 from EMACS_INT to ptrdiff_t.
10357 (make_window): Omit redundant initialization.
10359 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
10361 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
10363 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10365 * window.h (struct window): Change type of 'use_time' and
10366 'sequence_number' from Lisp_Object to int.
10367 * frame.c (make_frame): Adjust users accordingly.
10368 * print.c (print_object): Likewise.
10369 * window.c (select_window, Fwindow_use_time, make_parent_window)
10370 (make_window): Likewise.
10372 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10374 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
10375 enabled with --enable-checking=[all,glyphs] configure option.
10376 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10377 adjust comments accordingly.
10378 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
10379 undefined, adjust comments accordingly.
10380 * image.c: Likewise.

10500 Use sprintf return value instead of invoking strlen on result.
10501 In the old days this wasn't portable, since some sprintf
10502 implementations returned char *. But they died out years ago and
10503 Emacs already assumes sprintf returns int.
10504 Similarly for float_to_string.
10505 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10513 Use sprintf or float_to_string result to avoid need to call strlen.
10514 * data.c (Fnumber_to_string):
10515 Use make_unibyte_string, since the string must be ASCII.
10516 * lisp.h, print.c (float_to_string): Now returns int length.
10517 * term.c (produce_glyphless_glyph):
10518 Use sprintf result rather than recomputing it.
10520 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10521 * Makefile.in (ALL_CFLAGS):

10551 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10553 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10558 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10559 instead of truncating it to 63 (admittedly a generous limit).

10619 * keyboard.c (kbd_buffer_get_event):
10620 * process.c (Faccept_process_output):
10621 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10622 This improves on the previous patch, which introduced a bug
10623 when time_t is unsigned and as wide as intmax_t.
10624 See <http://bugs.gnu.org/9000#51>.
10626 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10655 language ID in the event parameters.
10657 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10658 event.code, not the obscure "character set ID".
10660 2012-06-23 Chong Yidong <cyd@gnu.org>

10689 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10691 Support higher-resolution time stamps (Bug#9000).
10692 The time stamps are only nanosecond-resolution at the C level,
10693 since that's the best that any real-world system supports now.
10694 But they are picosecond-resolution at the Lisp level, as that's
10695 easy, and leaves room for future OS improvements.
10697 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10700 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10701 Don't get current time unless it's needed.
10703 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10704 now provides it if it's absent.
10705 (start_atimer): Port to higher-res time stamps.
10706 Check for time stamp overflow. Don't get current time more
10707 often than is needed.
10709 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10710 Include systime.h, not time.h.
10711 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10713 * dired.c: Include stat-time.h.
10714 (Ffile-attributes): File times now have higher resolution.
10716 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10717 (struct image): Timestamp now has higher resolution.
10719 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10720 has at least microseconds now. All uses removed.
10721 (update_frame, update_single_window, update_window, update_frame_1)
10722 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10723 (duration_to_sec_usec): Remove; no longer needed.
10725 * editfns.c (time_overflow): Now extern.
10726 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10727 (float-time, Fformat_time_string, Fcurrent_time_string)
10728 (Fcurrent_time_zone): Accept and generate higher-resolution
10730 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10731 (decode_time_components, lisp_seconds_argument): New functions.
10732 (make_time): Now static.
10733 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10734 Report an error if the time is invalid, rather than having the caller
10737 * fileio.c: Include <stat-time.h>
10738 (Fcopy_file): Copy higher-resolution time stamps.
10739 Prefer to set the time stamp via a file descriptor if that works.
10740 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10741 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10742 (Fvisited_file_modtime, Fset_visited_file_modtime):
10743 Support higher-resolution time stamps.
10745 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10747 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10749 * image.c (prepare_image_for_display, clear_image_cache)
10750 (lookup_image): Port to higer-resolution time stamps.
10752 * keyboard.c (start_polling, bind_polling_period):
10753 Check for time stamp overflow.
10754 (read_char, kbd_buffer_get_event, timer_start_idle)
10755 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10756 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10757 Port to higher-resolution time stamps. Do not assume time_t is signed.
10758 (decode_timer): New function. Timers are now vectors of length 9,
10759 not 8, to accommodate the picosecond component.
10760 (timer_check_2): Use it.
10762 * nsterm.m (select_timeout, timeval_subtract): Remove.
10763 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10764 as they're a bit more accurate and handle overflow better.
10765 (ns_select): Change prototype to be compatible with pselect.
10766 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10767 * nsterm.h (ns_select): Adjust prototype.
10769 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10770 us-resolution time stamps.
10771 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10773 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10775 * lisp.h (time_overflow): New decl.
10776 (wait_reading_process_output): First arg is now intmax_t, not int,
10777 to accommodate larger waits.
10779 * process.h (struct Lisp_Process.read_output_delay):
10780 Now counts nanoseconds, not microseconds.
10781 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10783 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10784 (wait_reading_process_output):
10785 Port to ns-resolution time stamps.
10786 (Faccept_process_output, wait_reading_process_output):
10787 Check for time stamp overflow. Do not assume time_t is signed.
10788 (select_wrapper): Remove; we now use pselect.
10789 (Fprocess_attributes): Now generates ns-resolution time stamps.
10791 * sysdep.c: Include utimens.h. Don't include utime.h
10792 or worry about struct utimbuf; gnulib does that for us now.
10793 (gettimeofday): Remove; gnulib provides a substitute.
10794 (make_timeval): New function.
10795 (set_file_times): Now sets ns-resolution time stamps.
10796 New arg FD; all uses changed.
10797 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10798 (system_process_attributes):
10799 Now returns ns-resolution time stamp. All uses changed.
10800 Check for time stamp overflow.
10802 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10803 provides a substitute now.
10805 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10806 since it guarantees struct timespec.
10807 (EMACS_TIME): Now struct timespec, so that we can support
10808 ns-resolution time stamps.
10809 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10810 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10811 (EMACS_USECS): Remove.
10812 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10813 so multiply the arg by 1000 before storing it.
10814 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10816 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10817 Port to ns-resolution time stamps.
10818 (EMACS_TIME_NEG_P): Remove; replaced by....
10819 (EMACS_TIME_SIGN): New macro.
10820 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10821 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10822 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10823 (make_timeval, make_lisp_time, decode_time_components): New decls.
10824 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10825 that it mishandled time_t overflow. You can't compare by subtracting!
10826 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10827 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10829 * term.c: Include <sys/time.h>.
10830 (timeval_to_Time): New function, for proper overflow wraparound.
10831 (term_mouse_position, term_mouse_click): Use it.
10833 * undo.c (record_first_change): Support higher-resolution time stamps
10834 in the undo buffer.
10835 (Fprimitive_undo): Use them when restoring time stamps.
10837 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10838 (w32_get_internal_run_time):
10839 Port to higher-resolution Emacs time stamps.

11286 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11288 * doprnt.c (doprnt): Truncate multibyte char correctly.
11289 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11290 would mishandle a string argument "Xc" if X was a multibyte
11291 character of length 2: it would truncate after X's first byte
11292 rather than including all of X.
11294 2012-06-06 Chong Yidong <cyd@gnu.org>
11296 * buffer.c (word_wrap): Doc fix.
11298 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
11300 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.
11302 2012-06-03 Glenn Morris <rgm@gnu.org>
11304 * xdisp.c (tool-bar-style): Doc fix.
11306 2012-06-03 Ulrich Müller <ulm@gentoo.org>
11308 * Makefile.in (PAXCTL): Define.
11309 (temacs$(EXEEXT)): Disable memory randomization for the temacs
11310 binary via PaX flags if the paxctl utility is available.
11311 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11312 Restore PaX flags to their default. (Bug#11398)
11314 2012-06-03 Chong Yidong <cyd@gnu.org>
11316 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11317 buffer (Bug#11226).
11319 2012-06-03 Chong Yidong <cyd@gnu.org>
11321 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
11322 (note_mode_line_or_margin_highlight): If there is no help echo,
11323 use mode-line-default-help-echo. Handle the case where the mouse
11324 position is past the end of the mode line string.
11326 * buffer.c (buffer_local_value_1): New function, split from
11327 Fbuffer_local_value; can return Qunbound.
11328 (Fbuffer_local_value): Use it.
11329 (Vmode_line_format): Docstring tweaks.
11331 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11333 * sysdep.c (system_process_attributes): Improve comment.
11335 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
11337 * keyboard.c: Export real-this-command to Elisp.
11338 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11339 and DEFVAR it. Update all users.
11341 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11343 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11345 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11346 Convert pctcpu and pctmem to Lisp float properly.
11347 Let the compiler fold better, as 100.0/0x8000 is exact.
11349 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11351 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11354 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11356 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11358 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11360 For a 'struct window', replace some Lisp_Object fields to
11361 bitfields where appropriate, remove unused fields.
11362 * window.h (struct window): Remove unused 'last_mark_x' and
11363 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11364 change its type from Lisp_Object to bitfield.
11365 Change type of 'force_start', 'optional_new_start',
11366 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11367 fields from Lisp_Object to bitfield. Adjust users accordingly.
11369 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11371 Pacify gcc -Wdouble-precision when using Xaw.
11372 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11373 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11374 Use 'float' consistently, rather than 'float' in most places
11375 and 'double' in a couple of places.
11377 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11379 * xdisp.c (handle_stop): Detect whether we have overlay strings
11380 loaded by testing it->current.overlay_string_index to be
11381 non-negative, instead of checking whether n_overlay_strings is
11382 positive. (Bug#11587)
11384 2012-05-31 Chong Yidong <cyd@gnu.org>
11386 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11388 * doc.c (Fsubstitute_command_keys): Doc fix.
11390 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11392 * search.c (search_buffer): Remove calls to
11393 r_alloc_inhibit_buffer_relocation, as it is now called by
11394 maybe_unify_char, which was the cause of relocation of buffer text
11397 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11399 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11400 for the duration of call to load_charset, to avoid problems with
11401 callers of maybe_unify_char that access buffer text through C
11404 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11405 decrement the inhibition flag, instead of just setting or
11408 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11410 Remove obsolete '#define static' cruft.
11411 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11412 This #undef was "temporary" in 2000; it is no longer needed
11413 now that '#define static' has gone away.
11414 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11415 (gray_bitmap_bits): Remove; no longer needed.
11416 All uses replaced with definiens.
11417 * xterm.c: Include "bitmaps/gray.xbm".
11419 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11421 Clean up __executable_start, monstartup when --enable-profiling.
11422 The following changes affect the code only when profiling.
11423 * dispnew.c (__executable_start): Rename from safe_bcopy.
11424 Define only on platforms that need it.
11425 * emacs.c: Include <sys/gmon.h> when profiling.
11426 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11427 (__executable_start): Remove decl, since lisp.h does it now.
11428 (safe_bcopy): Remove decl; no longer has that name.
11429 (main): Coalesce #if into single bit of code, for simplicity.
11430 Cast pointers to uintptr_t, since standard libraries want integers
11432 * lisp.h (__executable_start): New decl.
11434 2012-05-31 Glenn Morris <rgm@gnu.org>
11436 * image.c (Fimagemagick_types): Doc fix.
11438 2012-05-30 Jim Meyering <meyering@redhat.com>
11440 * callproc.c (Fcall_process_region): Include directory component
11441 in mkstemp error message (Bug#11586).
11443 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11445 * alloc.c, lisp.h (make_pure_vector): Now static.
11447 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
11449 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
11450 Move to byte-run.el.

11453 (Qdefun): Move from eval.c.
11454 * lisp.h (Qdefun): Remove.
11455 * lread.c (read1): Tiny simplification.
11457 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11459 Do not create empty overlays with the evaporate property (Bug#9642).
11460 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11461 Bug#9642, but explicitly check that the buffer the overlay would
11462 be moved to is live and rearrange lines to make sure that errors
11463 will not put the overlay in an inconsistent state.
11464 (Fdelete_overlay): Cosmetics.
11466 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11468 * w32term.c (my_bring_window_to_top): New function.
11469 (x_raise_frame): Use handle returned by DeferWindowPos, which
11470 could be different from the original one.
11471 Call my_bring_window_to_top instead of my_set_foreground_window.
11474 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11475 by calling BringWindowToTop.

11480 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11482 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11483 This avoids undefined behavior that might cause the eassert
11484 to not catch an out-of-range value.
11486 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11488 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11489 Update dependencies.
11491 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11493 * bidi.c (bidi_mirror_char): Fix last change.
11495 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11497 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11498 when referring to sectname field in printf format.
11500 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11502 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11503 Only r_alloc_inhibit_buffer_relocation needed to be added;
11504 the others were already declared.
11506 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11507 before checking whether it's out of range. Put the check inside
11509 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11511 2012-05-27 Ken Brown <kbrown@cornell.edu>
11513 * callproc.c (Fcall_process): Restore a line that was accidentally
11514 commented out in the 2011-02-13 change (bug#11547).
11516 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11518 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11519 defined on ralloc.c.
11521 * buffer.c [REL_ALLOC]: Remove prototypes of
11522 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11523 they are now on lisp.h.
11525 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11527 * search.c (search_buffer): Use it to inhibit relocation of buffer
11528 text while re_search_2 is doing its job, because re_search_2 is
11529 passed C pointers to buffer text. (Bug#11519)
11531 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11532 Update value to 24.
11534 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11535 state after an additional call to move_it_in_display_line_to, keep
11536 the values of it->max_ascent and it->max_descent found for the
11538 (pos_visible_p): Revert the comparison against bottom_y to what it
11539 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11542 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11544 Fix coding-related core dumps with gcc -ftrapv.
11545 The code was computing A - B, where A and B are pointers, and B is
11546 random garbage. This can lead to core dumps on platforms that
11547 have special pointer registers, and it also leads to core dumps on
11548 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11549 A - B only when B is initialized properly.
11550 * coding.c (coding_set_source, coding_set_destination): Return void.
11551 (coding_change_source, coding_change_destinations): New functions,
11552 with the old behaviors of coding_set_source and coding_set_destination.
11553 All callers that need an offset changed to use these new functions.
11555 2012-05-26 Glenn Morris <rgm@gnu.org>
11557 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11559 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11561 Extend mouse support on W32 text-mode console.
11562 * xdisp.c (draw_row_with_mouse_face):
11563 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11565 * w32console.c: Include window.h.
11566 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11568 (initialize_w32_display): Initialize mouse-highlight data.
11570 * w32inevt.c: Include termchar.h and window.h.
11571 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11572 moves, call note_mouse_highlight. If help_echo changed, call
11573 gen_help_event to produce help-echo message in the echo area.
11574 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11577 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11579 * lread.c (read1): Simplify slightly to avoid an overflow warning
11580 with GCC 4.7.0 on x86-64.
11582 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11584 * bidi.c (bidi_mirror_char): Revert last change: an int is
11585 definitely wide enough here.
11587 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11589 Fix integer width and related bugs (Bug#9874).
11590 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11591 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11592 (string_bytes, check_sblock, allocate_string_data):
11593 (compact_small_strings, Fmake_bool_vector, make_string)
11594 (make_unibyte_string, make_multibyte_string)
11595 (make_string_from_bytes, make_specified_string)
11596 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11597 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11599 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11600 (allocate_pseudovector):
11601 Use int, not EMACS_INT, where int is wide enough.
11602 (inhibit_garbage_collection, Fgarbage_collect):
11603 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11604 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11605 int might not be wide enough.
11606 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11607 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11608 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11609 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11610 (bidi_level_of_next_char, bidi_move_to_visually_next):
11611 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11612 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11613 (Fkill_buffer, Fset_buffer_major_mode)
11614 (advance_to_char_boundary, Fbuffer_swap_text)
11615 (Fset_buffer_multibyte, overlays_at, overlays_in)
11616 (overlay_touches_p, struct sortvec, record_overlay_string)
11617 (overlay_strings, recenter_overlay_lists)
11618 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11619 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11620 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11621 (Foverlay_recenter, last_overlay_modification_hooks_used)
11622 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11623 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11624 (validate_region): Omit unnecessary test for b <= e,
11625 since that's guaranteed by the previous test.
11626 (adjust_overlays_for_delete): Avoid pos + length overflow.
11627 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11628 (report_overlay_modification):
11629 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11630 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11631 Omit pointer cast, which isn't needed anyway, and doesn't work
11632 after the EMACS_INT -> ptrdiff_t change.
11633 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11634 * buffer.h: Adjust decls to match defn changes elsewhere.
11635 (struct buffer_text, struct buffer):
11636 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11637 Use EMACS_INT, not int, where int might not be wide enough.
11638 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11639 not int, to avoid needless 32-bit limit on 64-bit hosts.
11640 (exec_byte_code): Use tighter memory-full test, one that checks
11641 for alloca overflow. Don't compute the address of the object just
11642 before an array, as that's not portable. Use EMACS_INT, not
11643 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11644 * callint.c (Fcall_interactively):
11645 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11646 * callproc.c (call_process_kill, Fcall_process):
11647 Don't assume pid_t fits into an Emacs fixnum.
11648 (call_process_cleanup, Fcall_process, child_setup):
11649 Don't assume pid_t fits into int.
11650 (call_process_cleanup, Fcall_process, delete_temp_file)
11651 (Fcall_process_region):
11652 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11653 (Fcall_process): Simplify handling of volatile integers.
11654 Use int, not EMACS_INT, where int will do.
11655 * casefiddle.c (casify_object, casify_region, operate_on_word)
11656 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11657 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11658 (casify_object): Avoid integer overflow when overallocating buffer.
11659 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11660 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11661 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11662 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11663 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11664 integers are now checked earlier. All uses replaced with XINT.
11666 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11667 For CCL_MapSingle, check that content and value are in int range.
11668 (ccl_driver, Fregister_code_conversion_map):
11669 Check that Vcode_version_map_vector is a vector.
11670 (resolve_symbol_ccl_program): Check that vector header is in range.
11671 Always copy the vector, so that we can check its contents reliably
11672 now rather than having to recheck each instruction as it's being
11673 executed. Check that vector words fit in 'int'.
11674 (ccl_get_compiled_code, Fregister_ccl_program)
11675 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11676 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11677 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11678 contents are in range.
11679 (Fccl_execute_on_string): Check that status is in range.
11680 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11681 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11682 Accept and return EMACS_INT, not int, because callers can pass values
11683 out of 'int' range.
11684 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11685 (multibyte_chars_in_text, parse_str_as_multibyte)

11687 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11688 (string_escape_byte8, Fget_byte):
11689 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11690 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11691 avoid mishandling large integers.
11692 * character.h: Adjust decls to match defn changes elsewhere.
11693 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11694 (Ffind_charset_region):
11695 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11696 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11697 (load_charset_map_from_vector, Fdefine_charset_internal):
11698 Don't assume fixnum fits in int.
11699 (load_charset_map_from_vector, Fmap_charset_chars):
11700 Remove now-unnecessary CHECK_NATNUMs.
11701 (Fdefine_charset_internal): Check ranges here, more carefully.
11702 Don't rely on undefined behavior with signed left shift overflow.
11703 Don't assume unsigned int fits into fixnum, or that fixnum fits
11704 into unsigned int. Don't require max_code to be a valid fixnum;
11705 that's not true for gb10830 4-byte on a 32-bit host. Allow

12377 * xterm.c (x_x_to_emacs_modifiers):
12378 Don't assume EMACS_INT overflows nicely into int.
12379 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12380 may come from Lisp.
12381 (handle_one_xevent): NATNUMP can eval its arg twice.
12382 (x_connection_closed):
12383 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12384 * xterm.h: Adjust decls to match defn changes elsewhere.
12385 (struct scroll_bar): Use struct vectorlike_header
12386 rather than rolling our own approximation.
12387 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12389 2012-05-25 Glenn Morris <rgm@gnu.org>
12391 * lisp.mk (lisp): Update for more files being compiled now.
12393 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12395 * lread.c: Remove `read_pure' which makes no difference.
12396 (read_pure): Remove var.
12397 (unreadpure): Remove function.
12398 (readevalloop): Don't call read_list with -1 flag.
12399 (read1, read_vector): Don't test read_pure any more.
12400 (read_list): Simplify.
12402 * fileio.c, character.h: Minor style tweaks.
12404 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12406 * window.h (clip_changed): Remove useless declaration.
12408 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12410 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12411 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12413 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12416 This directory predates autoconf and is no longer needed nowadays.
12417 Move its few remaining bits of functionality to where they're needed.
12418 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12419 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12420 * m/template.h: Remove.
12421 * Makefile.in (M_FILE): Remove. All uses removed.
12422 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12423 * lisp.h (USE_LSB_TAG):
12424 * mem-limits.h (EXCEEDS_LISP_PTR):
12425 Use VAL_MAX, not VALBITS, in #if.
12426 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12427 (EMACS_UINT): Define unconditionally now.
12428 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12429 (BITS_PER_EMACS_INT): New constants, replacing
12430 what used to be in config.h, but not useful in #if.
12431 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12432 define them any more.
12433 (VAL_MAX): New macro.
12435 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12436 BITS_PER_EMACS_INT, in #if.
12437 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12438 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12439 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12440 * s/ms-w32.h (DATA_START):
12441 Move here from removed file m/intel386.h.
12442 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12443 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12445 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12447 Assume C89 or later.
12448 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12449 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12451 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12452 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12453 * textprop.c, tparam.c (NULL): Remove.
12454 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12455 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12456 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12457 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12458 * xterm.c (input_signal_count): Assume volatile works.
12460 2012-05-21 Ken Brown <kbrown@cornell.edu>
12462 * xgselect.c (xg_select): Fix first argument in call to 'select'
12465 2012-05-20 Ken Brown <kbrown@cornell.edu>
12467 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12468 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12470 2012-05-19 Ken Brown <kbrown@cornell.edu>
12472 * xfns.c (x_in_use): Remove `static' qualifier.
12473 * xterm.h (x_in_use): Declare.
12474 * xgselect.c: Include xterm.h.
12475 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12476 and `display_arg' (bug#9754).
12478 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12480 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12482 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12483 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12485 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12487 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12489 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12490 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12492 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12493 reference to image_cache->refcount.
12494 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12496 2012-05-17 Juri Linkov <juri@jurta.org>
12498 * search.c (Fword_search_regexp, Fword_search_backward)
12499 (Fword_search_forward, Fword_search_backward_lax)
12500 (Fword_search_forward_lax): Move functions to isearch.el
12501 (bug#10145, bug#11381).
12503 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12505 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12507 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12509 * lread.c (init_obarray): Declare Qt and Qnil as special.
12511 2012-05-14 Glenn Morris <rgm@gnu.org>
12513 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12514 Put "libexec" before "bin", for the sake of init_callproc_1.
12516 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12518 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12520 * unexaix.c: Port to more-recent AIX compilers.
12521 (report_error, report_error_1, make_hdr, copy_sym)
12522 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12523 Make arguments const char *, not char *, to avoid violations of C
12524 standard and to fix some AIX warnings reported by Gilles Pion.
12526 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12528 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12529 already have overlays loaded.
12530 (handle_single_display_spec): Before returning without displaying
12531 fringe bitmap, synchronize the bidi iterator with the main display
12532 iterator, by calling iterate_out_of_display_property.
12533 (iterate_out_of_display_property): Detect buffer iteration by
12534 testing that it->string is a Lisp string.
12535 (get_next_display_element): When the current object is exhausted,
12536 and there's something on it->stack, call set_iterator_to_next to
12537 proceed with what's on the stack, instead of returning zero.
12538 (set_iterator_to_next): If called at the end of a Lisp string,
12539 proceed to consider_string_end without incrementing string
12540 position. Don't increment display vector index past the end of
12541 the display vector. (Bug#11417)
12542 (pos_visible_p): Don't report a position visible when move_it_to
12543 stopped at the last line of window, which happens to be scanned
12544 backwards by the bidi iteration. (Bug#11464)
12546 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12548 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12549 and right-margin display specs even if the spec is invalid or we
12550 are on a TTY, and thus unable to display on the fringes.
12551 That's because the text with the property will not be displayed anyway,
12552 so we need to signal to the caller that this is a "replacing"
12553 display spec. This fixes display when the spec is invalid or we
12556 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12558 * unexaix.c (make_hdr): Fix typo in prototype.
12559 This bug broke the build on AIX. Problem reported by Gilles Pion.
12561 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12563 * keyboard.c (kbd_buffer_get_event): Read special events also in
12564 batch mode. (Bug#11415)
12566 2012-05-12 Glenn Morris <rgm@gnu.org>
12568 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12570 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12572 * lisp.mk (lisp): Add newcomment.elc.
12574 2012-05-12 Glenn Morris <rgm@gnu.org>
12576 * Makefile.in (MKDIR_P): New, set by configure.
12577 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12579 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12581 Remove unused function hourglass_started.
12582 * dispextern.h (hourglass_started):
12583 * w32fns.c (hourglass_started):
12584 * xdisp.c (hourglass_started): Remove.
12586 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12588 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12589 Update dependencies.
12591 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12593 * xgselect.c (xg_select): Put maxfds+1 into a var.
12594 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12596 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12598 2012-05-10 Dave Abrahams <dave@boostpro.com>
12600 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12601 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12603 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12605 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12606 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12607 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12608 Initialize xd_registered_buses.
12610 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12612 Untag more efficiently if USE_LSB_TAG.
12613 This is based on a proposal by YAMAMOTO Mitsuharu in
12614 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12615 For an admittedly artificial (nth 8000 longlist) benchmark on
12616 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12617 Emacs's overall text size by 1%.
12618 * lisp.h (XUNTAG): New macro.
12619 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12620 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12621 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12622 * eval.c (Fautoload):
12623 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12624 * frame.h (XFRAME): Use XUNTAG.
12626 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12627 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12628 Remove unportable assumptions about print widths of types like
12630 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12631 intptr_t when converting between pointer and integer, to avoid GCC
12632 warnings about wrong width.
12634 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12636 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12637 stack for each reader_thread, instead of defaulting to 8MB
12638 determined by the linker. This avoids failures in creating
12639 subprocesses on Windows 7, see the discussion in this thread:
12640 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12642 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12644 Fix up display of the *Minibuf-0* buffer in the mini window.
12645 * keyboard.c (read_char): Don't clear the echo area if there's no
12647 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12648 contents of *Minibuf-0*) if there's no message displayed in its stead.
12650 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12652 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12655 2012-05-06 Chong Yidong <cyd@gnu.org>
12657 * lisp.mk (lisp): Update.
12659 2012-05-05 Jim Meyering <meyering@redhat.com>
12661 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12663 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12665 * data.c (PUT_ERROR): New macro.
12666 (syms_of_data): Use it. Add new error type `user-error'.
12667 * undo.c (user_error): New function.
12668 (Fprimitive_undo): Use it.
12669 * print.c (print_error_message): Adjust print style for `user-error'.
12670 * keyboard.c (user_error): New function.
12671 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12673 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12675 Do not limit current-time-string to years 1000..9999.
12676 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12677 (Fcurrent_time_string): Support any year that is supported by the
12678 underlying localtime representation. Don't use asctime, as it
12679 has undefined behavior for years outside the range -999..9999.
12681 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12683 Fix race conditions involving setenv, gmtime, localtime, asctime.
12684 Without this fix, interrupts could mess up code that uses these
12685 nonreentrant functions, since setting TZ invalidates existing
12686 tm_zone or tzname values, and since most of these functions return
12687 pointers to static storage.
12688 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12689 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12690 Grow the critical sections to include not just invoking
12691 localtime/gmtime, but also accessing these functions' results
12692 including their tm_zone values if any, and any related TZ setting.
12693 (format_time_string): Last arg is now struct tm *, not struct tm **,
12694 so that the struct tm is saved in the critical section.
12695 All callers changed. Simplify allocation of initial buffer, partly
12696 motivated by the fact that memory allocation needs to be outside
12697 the critical section.
12699 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12701 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12702 with RESET_INTERVAL.
12704 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12705 Remove duplicated buffer name initialization.
12707 2012-05-02 Jim Meyering <jim@meyering.net>
12709 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12711 * xfns.c (x_window): Use xstrdup (Bug#11375).
12713 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12715 * xdisp.c (pos_visible_p): If already at a newline from the
12716 display string before the 'while' loop, don't walk back the glyphs
12717 from it3.glyph_row. Solves assertion violation when the display
12718 string begins with a newline (egg.el). (Bug#11367)
12720 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12722 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12725 2012-05-01 Glenn Morris <rgm@gnu.org>
12727 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12728 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12729 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12730 All were removed before 23.1.
12732 * dispnew.c: Remove HAVE_LIBNCURSES test;
12733 it is always true on relevant platforms.
12735 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12736 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12738 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12740 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12742 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12743 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12746 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12748 Do not avoid creating empty evaporating overlays (Bug#9642).
12749 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12750 That is, do not delete an evaporating overlay if it becomes
12751 empty after its bounds are adjusted to fit within its buffer.
12752 This fix caused other problems, and I'm reverting it until we get
12753 to the bottom of them.
12755 2012-04-27 Chong Yidong <cyd@gnu.org>
12757 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12759 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12761 * xdisp.c (pos_visible_p): If the window start position is beyond
12762 ZV, start the display from buffer beginning. Prevents assertion
12763 violation in init_iterator when the minibuffer window is scrolled
12764 via the scroll bar.
12766 * window.c (window_scroll_pixel_based): Likewise.
12768 2012-04-27 Chong Yidong <cyd@gnu.org>
12770 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12772 2012-04-27 Glenn Morris <rgm@gnu.org>
12774 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12775 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12777 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12779 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12780 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12782 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12784 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12785 display element, check also the underlying string or buffer
12786 character. (Bug#11341)
12788 * w32menu.c: Include w32heap.h.
12789 (add_menu_item): If the call to AppendMenuW (via
12790 unicode_append_menu) fails, disable Unicode menus only if we are
12791 running on Windows 9X/Me.
12793 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12795 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12796 (xgetint): Add missing shift for LSB tags.
12798 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12800 * keyboard.c (read_char): Don't wipe echo area for select window
12801 events: These might get delayed via `mouse-autoselect-window'
12804 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12806 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12807 manipulation of :loaded-from data.
12809 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12811 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12812 now a cons (bug#11311).
12814 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12816 Do not create empty overlays with the evaporate property (Bug#9642).
12817 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12818 if it becomes empty after its bounds are adjusted to fit within
12819 its buffer. Without this fix, in a nonempty buffer (let ((o
12820 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))

13026 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13027 (NEED_MEM_INSERT): New macro.
13028 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13029 Remove one incorrect comment and fix another.

13096 2012-04-11 Daniel Colascione <dancol@dancol.org>
13098 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13099 against is gone. It's better to use vfork now so that when Cygwin
13100 gains a new, working vfork, we use it automatically (bug#10398).
13102 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13155 * minibuf.c (Fread_variable): Callers changed.
13157 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13159 * xdisp.c (set_cursor_from_row): If the display string appears in
13160 the buffer at position that is closer to point than the position
13161 after the display string, display the cursor on the first glyph of
13162 the display string. Fixes cursor display when a 'display' text
13163 property immediately follows invisible text. (Bug#11094)
13165 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13167 composite.c: use 'double' consistently
13168 * composite.c (get_composition_id): Use 'double' consistently
13169 instead of converting 'float' to 'double' and vice versa; this is
13170 easier to understand and avoids a GCC warning.
13172 2012-04-09 Glenn Morris <rgm@gnu.org>
13174 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13175 preparation for dumping it with emacs. (Bug#4789)

13224 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13226 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

13239 point, use it.vpos to compute how many lines to backtrack after
13240 move_it_to point. (Bug#11133)
13242 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13244 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13245 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13246 about subtle differences between FETCH_CHAR* and STRING_CHAR*

13249 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13251 2012-04-04 Chong Yidong <cyd@gnu.org>
13253 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13255 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13257 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13258 instead of alloca. (Bug#11138)
13260 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13262 * w32menu.c (is_simple_dialog): Properly check lisp types.
13265 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13267 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13268 position we get to after a call to move_it_to fails the
13269 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13270 only if we wind up in a string from display property. (Bug#11063)
13272 * window.c (Fdelete_other_windows_internal): Invalidate the row
13273 and column information about mouse highlight, so that redisplay
13274 restores it after reallocating the glyph matrices. (Bug#7464)
13276 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13277 string comes from a `display' text property, use the buffer
13278 position of that property as if we actually saw that position in
13280 (move_it_by_lines): Remove the assertion that
13281 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13282 violated when there's a before-string at the beginning of a line.
13285 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13287 * xdisp.c (append_space_for_newline): If the default face was
13288 remapped, use the remapped face for the appended newline.
13289 (extend_face_to_end_of_line): Use the remapped default face for
13290 extending the face to the end of the line.
13291 (display_line): Call extend_face_to_end_of_line when the default
13292 face was remapped. (Bug#11068)
13294 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13296 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13298 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13300 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13302 2012-03-27 Glenn Morris <rgm@gnu.org>
13304 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13307 2012-03-26 Kenichi Handa <handa@m17n.org>
13309 * dispextern.h (struct glyph): Fix previous change. Change the
13310 bit length of glyphless.ch to 25 (Bug#11082).
13312 2012-03-26 Chong Yidong <cyd@gnu.org>
13314 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13315 (command_loop_1): Use it; inhibit selection update for
13316 handle-select-window too (Bug#8996).
13318 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13320 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13322 2012-03-25 Kenichi Handa <handa@m17n.org>
13324 * dispextern.h (struct glyph): Change the bit length of
13325 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13327 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13329 * s/ms-w32.h (tzname): Include time.h before redirecting to
13330 _tzname. Fixes the MSVC build. (Bug#9960)
13332 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13334 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13337 * xterm.c (XTread_socket): Only modify handling_signal if
13338 !SYNC_INPUT. (Bug#11080)
13340 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13342 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13343 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13344 when fetching a multibyte character consumes more bytes than
13345 CHAR_BYTES returns, due to unification of CJK characters in
13346 string_char. (Bug#11073)
13348 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13350 * process.c (wait_reading_process_output): Handle pty disconnect
13351 by refraining from sending oneself a SIGCHLD (bug#10933).
13353 2012-03-22 Chong Yidong <cyd@gnu.org>

13357 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13358 Mark string as coming from a prefix property.
13359 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13360 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13362 2012-03-21 Chong Yidong <cyd@gnu.org>
13364 * xfaces.c (Vface_remapping_alist): Doc fix.
13366 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13368 * w32proc.c (Fw32_set_console_codepage)
13369 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

13374 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13375 to reflect default non-nil value of redisplay-dont-pause.
13377 2012-03-19 Kenichi Handa <handa@m17n.org>
13379 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13380 it fit in a valid range (Bug#11003).
13382 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13384 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13385 that is not from display property, accept the row as a "cursor
13386 row" if one of the string's character has a non-nil `cursor'
13387 property. Fixes cursor positioning when there are newlines in
13388 overlay strings, e.g. in icomplete.el. (Bug#11035)
13390 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13392 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13394 2012-03-12 Chong Yidong <cyd@gnu.org>
13396 * eval.c (inhibit_lisp_code): Rename from
13397 inhibit_window_configuration_change_hook; move from window.c.
13399 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13400 * window.c (run_window_configuration_change_hook)
13401 (syms_of_window): Callers changed.

13416 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13418 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13420 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13421 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13424 2012-03-03 Glenn Morris <rgm@gnu.org>
13426 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13428 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13430 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13431 position past the first glyph_row that ends at ZV. (Bug#10902)
13432 (redisplay_window, next_element_from_string): Fix typos in
13434 (redisplay_window): Pass to move_it_vertically the margin in
13435 pixels, not in screen lines.
13437 2012-03-02 Glenn Morris <rgm@gnu.org>
13439 * buffer.c (buffer-list-update-hook): Doc fix.
13441 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13443 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13444 push_it before setting up the iterator for the first overlay
13445 string, even if we have an empty string loaded.
13446 (next_overlay_string): If there's an empty string on the iterator
13447 stack, pop the stack. (Bug#10903)
13449 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13451 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13452 Suggested by Stefan Monnier in
13453 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13454 * alloc.c (widen_to_Lisp_Object): New static function.
13455 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13456 and widening them to Lisp_Objects. This would work even if
13457 USE_LSB_TAG is defined and wide integers are used, which might
13458 happen in a future version of Emacs.
13460 2012-02-25 Chong Yidong <cyd@gnu.org>
13462 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13465 * xselect.c (Fx_selection_exists_p): Doc fix.
13466 (x_clipboard_manager_save_all): Print an informative message
13467 before saving to clipboard manager.
13469 2012-02-24 Chong Yidong <cyd@gnu.org>
13471 * keyboard.c (process_special_events): Handle all X selection
13472 requests in kbd_buffer, not just the next one (Bug#8869).
13474 2012-02-23 Chong Yidong <cyd@gnu.org>
13476 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13477 call when setting menu-bar-lines and tool-bar-lines parameters.
13478 (unwind_create_frame_1): New helper function.
13480 * window.c (inhibit_window_configuration_change_hook): New var.
13481 (run_window_configuration_change_hook): Obey it.
13482 (syms_of_window): Initialize it.
13484 2012-02-22 Chong Yidong <cyd@gnu.org>
13486 * xterm.c (x_draw_image_relief): Add missing type check for
13487 Vtool_bar_button_margin (Bug#10743).
13489 2012-02-21 Chong Yidong <cyd@gnu.org>
13491 * fileio.c (Vfile_name_handler_alist): Doc fix.
13493 * buffer.c (Fget_file_buffer): Protect against invalid file
13494 handler return value.
13496 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13498 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13499 when computing $valmask.
13501 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13502 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13503 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13504 It's useless in that case, and it can cause problems on hosts
13505 that allocate halves of EMACS_INT values separately.
13506 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13507 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13508 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13509 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13510 it avoids undefined behavior on hosts where shifting right by more
13511 than the word width has undefined behavior.
13513 2012-02-19 Chong Yidong <cyd@gnu.org>
13515 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13516 (Funhandled_file_name_directory, Ffile_name_as_directory)
13517 (Fdirectory_file_name, Fexpand_file_name)
13518 (Fsubstitute_in_file_name): Protect against invalid file handler
13519 return values (Bug#10845).
13521 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13523 * .gdbinit (pitx): Fix incorrect references to fields of the
13526 2012-02-17 Chong Yidong <cyd@gnu.org>
13528 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
13530 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13532 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13533 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13535 2012-02-15 Chong Yidong <cyd@gnu.org>
13537 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13538 marked as special. Also, starting docstrings with * is obsolete.
13540 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13542 * gnutls.c (emacs_gnutls_write): Fix last change.
13544 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
13546 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
13549 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
13551 * keymap.c (Fsingle_key_description): Handle char ranges.
13553 2012-02-12 Chong Yidong <cyd@gnu.org>
13555 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13556 as that creates a dangerous corner case.
13558 * window.c (Fdelete_window_internal): Invalidate the mouse
13559 highlight (Bug#9904).
13561 2012-02-12 Glenn Morris <rgm@gnu.org>
13563 * xselect.c (Fx_own_selection_internal)
13564 (Fx_get_selection_internal, Fx_disown_selection_internal)
13565 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13566 * nsselect.m (Fx_own_selection_internal)
13567 (Fx_disown_selection_internal, Fx_selection_exists_p)
13568 (Fx_selection_owner_p, Fx_get_selection_internal):
13569 Sync docs and argument specs with the xselect.c versions.
13571 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13573 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13575 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13577 * w32select.c (Fx_selection_exists_p): Sync doc string and
13578 argument list with xselect.c. (Bug#10783)
13580 * w16select.c (Fx_selection_exists_p): Sync doc string and
13581 argument list with xselect.c. (Bug#10783)
13583 2012-02-10 Glenn Morris <rgm@gnu.org>
13585 * fns.c (Fsecure_hash): Doc fix.
13587 2012-02-09 Kenichi Handa <handa@m17n.org>
13589 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13591 2012-02-07 Chong Yidong <cyd@gnu.org>
13593 * buffer.c (Fbuffer_local_variables)
13594 (buffer_lisp_local_variables): Handle unbound vars correctly;
13595 don't let Qunbound leak into Lisp.
13597 2012-02-07 Glenn Morris <rgm@gnu.org>
13599 * image.c (Fimagemagick_types): Doc fix.
13601 * image.c (imagemagick-render-type): Change it from a lisp object
13602 to an integer. Move the doc here from the lisp manual.
13603 Treat all values not equal to 0 the same.
13605 2012-02-06 Chong Yidong <cyd@gnu.org>
13607 * doc.c (store_function_docstring): Avoid applying docstring of
13608 alias to base function (Bug#2603).
13610 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

13615 2012-02-04 Chong Yidong <cyd@gnu.org>
13617 * nsterm.m: Declare a global (Bug#10694).
13619 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13621 * w32.c (get_emacs_configuration_options):
13622 Include --enable-checking, if specified, in the return value.
13624 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13626 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13627 after rounding frame sizes. (Bug#9723)
13629 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13631 * keyboard.c (adjust_point_for_property): Don't position point
13632 before BEGV. (Bug#10696)
13634 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13636 Handle overflow when computing char display width (Bug#9496).
13637 * character.c (char_width): Return EMACS_INT, not int.
13638 (char_width, c_string_width): Check for overflow when
13639 computing the width; this is possible now that individual
13640 characters can have unbounded width. Problem introduced
13641 by merge from Emacs 23 on 2012-01-19.
13643 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13645 * dbusbind.c (Fdbus_register_method): Mention the return value
13646 :ignore in the docstring.
13648 2012-02-02 Glenn Morris <rgm@gnu.org>
13650 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
13652 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
13653 Unconditionally set to t. (Bug#10673)

13658 2012-02-02 Kenichi Handa <handa@m17n.org>
13660 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13661 0, do not call append_composite_glyph.
13663 2012-02-02 Kenichi Handa <handa@m17n.org>
13665 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13667 (x_produce_glyphs): If the component of a composition is a null
13668 string, set it->pixel_width to 1 to avoid zero-width glyph.
13670 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13672 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13673 first 2 arguments are identical. This makes inserting large
13674 output from a subprocess an order of magnitude faster on
13675 MS-Windows, where all sbrk'ed memory is always contiguous.
13677 2012-01-31 Glenn Morris <rgm@gnu.org>
13679 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13715 2012-01-21 Chong Yidong <cyd@gnu.org>
13717 * floatfns.c (Fcopysign): Make the second argument non-optional,
13718 since nil is not allowed anyway.
13720 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13722 * process.c (read_process_output): Use p instead of XPROCESS (proc).
13723 (send_process): Likewise.
13725 2012-01-19 Martin Rudalics <rudalics@gmx.at>
13727 * window.c (save_window_save, Fcurrent_window_configuration)
13728 (Vwindow_persistent_parameters): Do not use Qstate.
13729 Rewrite doc-strings.
13731 2012-01-19 Kenichi Handa <handa@m17n.org>
13733 * character.c (char_width): New function.
13734 (Fchar_width, c_string_width, lisp_string_width):
13735 Use char_width (Bug#9496).

14294 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14295 is set, removing the need for VIRT_ADDRESS_VARIES.
14296 (PURE_P): Use a more-efficient implementation that needs just one
14297 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14298 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14299 to 4 (xorl, subq, cmpq, setbe).
14300 * alloc.c (pure): Always extern now, since that's the
14301 VIRT_ADDR_VARIES behavior.

14303 consistency with the new puresize.h.
14304 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14305 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14313 behave as if the cursor position were at the window margin.
14315 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14316 and the cursor position is out of bounds, behave as if the cursor
14317 position were at the window margin. (Bug#10075)
14319 2011-11-18 Chong Yidong <cyd@gnu.org>
14321 * window.c (Fwindow_combination_limit): Make first argument

14347 * dispnew.c (verify_row_hash): Call row_hash for computing the
14348 hash code of a row, instead of duplicating code from xdisp.c.
14350 * dispextern.h (row_hash): Add prototype.
14352 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

14388 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14390 * xdisp.c (display_line): Move the call to
14391 highlight_trailing_whitespace before the call to
14392 compute_line_metrics, since the latter needs to see the final
14393 faces of all the glyphs to compute ROW's hash value.
14394 Fixes assertion violations in row_equal_p. (Bug#10035)
14396 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14398 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

14403 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14404 with user-defined heap size. Bump the default size of the temacs

14408 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14409 current_matrix and desired_matrix. (Bug#9990)
14410 (verify_row_hash) [XASSERTS]: New function.

14457 Avoid some portability problems by eschewing 'extern inline' functions.
14458 The trivial performance wins aren't worth the portability hassles; see

14527 * xmenu.c (cleanup_widget_value_tree): New function.
14528 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14535 (window_box_width, window_box_left, window_box_left_offset)
14536 (window_box_right, window_box_right_offset): Declare extern.
14537 Otherwise, these inline functions do not conform to C99 and
14538 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14539 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14540 * intervals.c (adjust_intervals_for_insertion)

14543 (static_offset_intervals): Remove.
14544 (offset_intervals): Rewrite using the old contents of
14545 static_offset_intervals. The old version didn't conform to C99
14546 because an extern inline function contained a reference to an
14547 identifier with static linkage.

14666 * window.c (Fwindow_body_size): Mention in the doc string that the
14667 return value is in frame's canonical units. (Bug#9949)
14669 2011-11-03 Eli Zaretskii <eliz@gnu.org>
14671 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
14673 * w32fns.c (unwind_create_frame): If needed, free the glyph
14674 matrices of the partially constructed frame. (Bug#9943)
14675 * xfns.c (unwind_create_frame): Likewise.
14677 2011-11-01 Eli Zaretskii <eliz@gnu.org>
14679 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
14680 Don't stop backward scan on the continuation glyph, even though
14681 its CHARPOS is positive.
14682 (mouse_face_from_buffer_pos, note_mouse_highlight):
14683 Rename cover_string to disp_string.
14685 2011-11-01 Martin Rudalics <rudalics@gmx.at>
14687 * window.c (temp_output_buffer_show): Don't use
14688 Vtemp_buffer_show_specifiers.
14689 (Vtemp_buffer_show_specifiers): Remove unused variable.
14691 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14693 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14694 past the beginning of the current glyph matrix.
14696 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14698 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14699 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14700 HAVE_GTK3 (Bug#9869).
14702 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
14703 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14705 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14707 * xterm.c: Declare x_handle_net_wm_state to return int.
14708 (handle_one_xevent): Check if we are iconified but don't have
14709 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14710 (get_current_wm_state): Return non-zero if not hidden,
14711 check for _NET_WM_STATE_HIDDEN (Bug#9893).

14716 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14718 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14719 so that this new function doesn't get optimized away by a
14720 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14722 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14724 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14726 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14728 Fix the `xbytecode' command.
14729 * .gdbinit (xprintbytestr): New command.
14730 (xwhichsymbols): Rename from `which'; all callers changed.
14731 (xbytecode): Print the byte-code string as well.
14733 2011-10-29 Kim Storm <storm@cua.dk>
14735 * alloc.c (which_symbols): New function.
14737 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14739 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14742 2011-10-29 Glenn Morris <rgm@gnu.org>
14744 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14745 Not clear what it was for, and it causes various bugs. (Bug#9839)
14747 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14749 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14750 possible random value that matches one of those tested as
14751 condition to clear the mouse face.
14753 2011-10-28 Chong Yidong <cyd@gnu.org>
14755 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14757 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14759 * window.c (make_window): Initialize phys_cursor_on_p.
14761 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14763 * lisp.h (struct Lisp_Symbol): Update comments.
14765 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14767 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14769 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14771 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14772 <oslsachem@gmail.com> for helping to debug this.
14774 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14775 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14776 (g_b_init_get_glyph_outline_w): New static variables.
14777 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14778 (GetGlyphOutlineW_Proc): New typedefs.
14779 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14780 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14782 (w32font_open_internal, compute_metrics):
14783 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14784 instead of calling the "wide" APIs directly.
14786 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14788 * w32.h (syms_of_w32font): Add prototype.
14790 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14792 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14793 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14794 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14795 (Fmove_to_window_line): Doc fix.
14797 2011-10-27 Chong Yidong <cyd@gnu.org>
14799 * process.c (make_process): Set gnutls_state to NULL.
14801 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14802 non-NULL, regardless of GNUTLS_INITSTAGE.
14803 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14804 an error. Set process slots as soon as we allocate them.
14806 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14808 2011-10-27 Chong Yidong <cyd@gnu.org>
14810 * gnutls.c (emacs_gnutls_deinit): New function.
14811 Deallocate credentials structures as well as calling gnutls_deinit.
14812 (Fgnutls_deinit, Fgnutls_boot): Use it.
14814 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14815 (deactivate_process): Call emacs_gnutls_deinit.
14817 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14819 * image.c (x_create_x_image_and_pixmap):
14820 * w32.c (sys_rename, w32_delayed_load):
14821 * w32font.c (fill_in_logfont):
14822 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14824 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14826 * w32fns.c (w32_default_color_map): New function,
14827 extracted from Fw32_default_color_map.
14828 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14830 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14832 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14834 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14836 * keyboard.c (test_undefined): New function (bug#9751).
14837 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14839 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14841 * sysdep.c (init_sys_modes): Fix the check for the controlling
14842 terminal (Bug#6649).
14844 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14846 * dispextern.h (struct bidi_it): New member next_en_type.
14848 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14849 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14850 current character, check also for next_en_type being WEAK_EN.
14851 (bidi_resolve_weak): Don't enter the expensive loop if the current
14852 position is before next_en_pos. Record the bidi type of the first
14853 non-ET, non-BN character we find, in addition to its position.
14854 (bidi_level_of_next_char): Invalidate next_en_type when
14855 next_en_pos is over-stepped.
14857 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14859 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14860 * editfns.c: Rewrite current-time-zone so that it invokes
14861 the equivalent of (format-time-string "%Z") to get the time zone name.
14862 This fixes a bug when the time zone name contains characters that
14863 need converting from the system time locale to Emacs internal format.
14864 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14865 that patch fixed format-time-string to do the conversion, but
14866 I forgot to fix current-time-zone.
14867 (format_time_string): New function, containing most of
14868 what Fformat_time_string used to contain.
14869 (Fformat_time_string): Rewrite in terms of format_time_string.
14870 This doesn't change this function's behavior.
14871 (current-time-zone): Rewrite to use format_time_string.
14872 This fixes the bug reported by Michael Schierl in
14873 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14874 Jason Rumney's 2007-06-07 change worked around this bug, but
14876 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14878 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14880 * xdisp.c (start_display): If the character at POS is displayed
14881 via a display vector, reset IT->current.dpvec_index to zero.
14882 (try_window_reusing_current_matrix): If a line ends in a display
14883 vector or the next line starts in a display vector, continue
14884 redrawing the window even though the character position of
14885 start_row was reached.
14888 2011-10-18 Chong Yidong <cyd@gnu.org>
14890 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14891 with nobreak-char-display too.
14893 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14895 Fix part 3 of bug#9771.
14896 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14897 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14898 non-neutral characters if the current character is a paragraph
14899 separator (a.k.a. Newline). This avoids running the same
14900 expensive loop twice, once when we consume the preceding newline
14901 and the other time when the line actually needs to be displayed.
14902 Avoid the loop when we see neutrals on the base embedding level
14903 following a character whose directionality is the same as the
14904 paragraph's. This avoids running the expensive loop when a line
14905 ends in a long sequence of neutrals, like control characters.
14906 Add assertion against STRONG_AL type. Slightly rearrange code
14907 that determines the type of a neutral given the first non-neutral
14909 (bidi_level_of_next_char): Set next_en_pos to zero when
14910 invalidating its info.
14912 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14914 * xdisp.c (push_display_prop): Determine whether to record string
14915 or buffer position by IT->string, not by IT->method. Allow
14916 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14917 (move_it_vertically_backward): Don't look for character position
14918 immediately after the newline when in a continuation line.
14921 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14923 * window.c (coordinates_in_window): Rewrite and delabelize
14924 vertical border check. (Bug#5357) (Bug#9618)
14926 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14928 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14929 errors in XSetWindowBorder (bug#9310).
14931 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14933 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14934 avoid crash when xmalloc overrun checking is enabled.
14936 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14938 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14939 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14940 cursor motion with <left> and <right> arrow keys.
14942 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14943 some callers set that themselves.
14945 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14947 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14948 display string and the previous row comes from the same string and
14949 is empty. (Bug#9739) (Bug#9738)
14951 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14953 * doc.c (get_doc_string): Encode file name (bug#9735).
14955 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14957 * bidi.c (bidi_level_of_next_char):
14958 * xdisp.c (get_visually_first_element): Remove old incorrect
14959 comments regarding the Unicode Line Separator character.
14961 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14963 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14965 * alloc.c (Fgc_status): Do not access beyond zombies array
14966 boundary if nzombies > MAX_ZOMBIES.
14967 * alloc.c (dump_zombies): Add missing format specifier.
14969 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14971 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14972 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14974 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14975 Some packages use them to denote characters with modifiers.
14977 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14979 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14980 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14981 matching a pp-number. Rename parameter var to var1.
14983 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14985 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14987 2011-10-08 Glenn Morris <rgm@gnu.org>
14989 * callint.c (Fcall_interactively): Give a more explicit error for the
14990 'c' case with a non-character input. (Bug#8479)
14992 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14994 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14996 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14997 lines that are hscrolled on the left.
14999 * dispnew.c (buffer_posn_from_coords): Account for a possible
15000 presence of header-line. (Bug#4426)
15002 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15004 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15005 Don't advertise functionality which we discourage or doesn't work.
15007 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15009 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15010 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15011 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15012 this makes Emacs dump core during garbage collection on rare
15013 occasions. sizeof is obviously inferior to offsetof here, so
15014 stick with offsetof.
15015 (GC_POINTER_ALIGNMENT): New macro.
15016 (mark_memory): Omit 3rd (offset) arg; caller changed.
15017 Don't assume EMACS_INT alignment is the same as pointer alignment.
15019 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15021 * keyboard.c (read_key_sequence_remapped): New var.
15022 (read_key_sequence): Compute remapping in the right buffer.
15023 (command_loop_1): Use read_key_sequence's remapping directly.
15025 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15027 * dired.c (file_name_completion): Don't expand file name.
15028 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15029 before checking file name handler.
15031 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15032 they've been requested explicitly (bug#9591).
15034 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15036 * keymap.c (Fsingle_key_description): Use make_specified_string
15037 instead of build_string to build string from push_key_description.
15040 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15042 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15043 This fixes a Y2038 bug on 64-bit hosts.
15044 * buffer.c (reset_buffer):
15045 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15046 (Fclear_buffer_auto_save_failure):
15047 Use 0, not -1, to represent an unset failure time, since time_t
15048 might not be signed.
15050 Remove dependency on glibc malloc internals.
15051 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15052 Move back here from lisp.h, but with their new implementations.
15053 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15054 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15055 * charset.c (charset_table_init): New static var.
15056 (syms_of_charset): Use it instead of xmalloc. This removes a
15057 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15058 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15059 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15060 Move back to alloc.c.
15061 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15062 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15064 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15066 * nsterm.m (windowDidResize): Call x_set_window_size only when
15067 ns_in_resize is true. Otherwise set pixelwidth/height and
15068 call change_frame_size (Bug#9628).
15070 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15072 Port --enable-checking=all to Fedora 14 x86-64.
15073 * charset.c (syms_of_charset): Also account for glibc malloc's
15074 internal overhead when calculating the initial malloc maximum.
15076 Port --enable-checking=all to Fedora 14 x86.
15077 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15079 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15080 (overrun_check_realloc, overrun_check_free):
15081 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15082 That way, xmalloc returns a properly-aligned pointer even if
15083 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15084 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15085 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15086 into account when calculating the initial malloc maximum.
15087 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15088 Move here from alloc.c, so that charset.c can use it too.
15089 Properly align; the old code wasn't right for common 32-bit hosts
15090 when configured with --enable-checking=all.
15091 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15092 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15094 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15096 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15099 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15101 * xdisp.c (compute_display_string_end): If there's no display
15102 string at CHARPOS, return -1.
15104 * bidi.c (bidi_fetch_char): When compute_display_string_end
15105 returns a negative value, treat the character as a normal

15112 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15114 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15115 newline, reseat the iterator instead of bidi-iterating there one
15116 character at a time. (Bug#9610)
15117 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15118 TO_CHARPOS if the bidi iterator is at base embedding level.
15120 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15122 * lread.c (readevalloop): Use correct code for NBSP.

15125 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15127 * dbusbind.c (Fdbus_register_signal): When service is not
15128 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15130 2011-09-25 Glenn Morris <rgm@gnu.org>
15132 * buffer.c (truncate-lines): Doc fix.
15134 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

15149 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15151 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15152 Default value is now t. Doc fix.
15154 * indent.c (Fvertical_motion): Compute and apply the overshoot
15155 logic when moving up, not only when moving down. Fix the
15156 confusing name and values of the it_overshoot_expected variable;
15157 logic changes accordingly. (Bug#9254) (Bug#9549)
15159 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15160 CHARPOS is covered by a display string which includes newlines.
15161 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15162 is covered by a display string with embedded newlines.
15164 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15166 * dbusbind.c (Fdbus_register_signal): Add match rule to
15167 Vdbus_registered_objects_table. (Bug#9581)
15168 (Fdbus_register_method, Vdbus_registered_objects_table):
15171 2011-09-24 Jim Meyering <meyering@redhat.com>
15173 do not ignore write error for any output size
15174 The previous change was incomplete.
15175 While it makes emacs --batch detect the vast majority of stdout
15176 write failures, errors were still ignored whenever the output size is
15177 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15178 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15179 && echo FAIL: ignored write error
15180 FAIL: ignored write error
15181 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15182 && echo FAIL: ignored write error
15183 FAIL: ignored write error
15184 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15186 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15188 * emacs.c (Fkill_emacs): In noninteractive mode exit
15189 non-successfully if a write error occurred on stdout. (Bug#9574)
15191 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15193 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15196 * dispextern.h (struct it): Update the comment documenting what
15199 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15201 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15202 a display string, extend search for cursor position to end of row.
15203 (find_row_edges): If the row ends in a newline from a display
15204 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15205 Handle the case of a display string with multiple newlines.
15206 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15207 non-empty line. Fixes confusing cursor motion with arrow keys at
15208 the beginning of a line that starts with whitespace.
15210 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15212 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15215 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15217 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15218 boolean (Bug#9154).
15220 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15222 * xdisp.c (display_line): Record maximum and minimum buffer
15223 positions even if no glyphs were produced (e.g., by a zero-width
15224 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15225 buffer positions that will be removed from the glyph row because
15227 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15228 column is beyond frame width: don't subtract 1 "pixel" when
15229 computing width of the stretch.
15230 (reseat_at_next_visible_line_start): Undo the change made on
15231 2011-09-17 that saved paragraph information and restored it after
15232 the call to `reseat'. (Bug#9545)
15234 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15236 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15237 and turn window cursor on if cleared (Bug#9415).
15239 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15241 * search.c (boyer_moore): Take unibyte characters from pattern
15242 literally. (Bug#9458)
15244 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15246 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15248 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15250 Fix minor problem found by static checking.

15252 initialized, to pacify gcc -Wuninitialized.
15254 * fileio.c: Report proper errno when syscall falls.
15255 (Finsert_file_contents): Save and restore errno,
15256 so that report_file_error outputs the correct diagnostic.
15257 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15259 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15261 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15263 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15265 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15266 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15268 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15270 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15271 about the current paragraph and restore it after the call to reseat.
15273 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15274 (bidi_find_paragraph_start): Search back for paragraph beginning
15275 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15276 (bidi_move_to_visually_next): Only trigger paragraph-related
15277 computations when the last character is a newline or at EOB, not
15278 just any NEUTRAL_B. (Bug#9470)
15280 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15281 truncated lines if point is covered by a display string. (Bug#9524)
15283 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15285 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15286 (cons_to_x_long): New function.
15287 (lisp_data_to_selection_data): Use it. Correct the test for
15288 short-versus-long data; it was negated. Break out of vector
15289 loop, for efficiency, when a long datum is discovered.
15291 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15293 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15295 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15297 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15298 GCC PR/17406) by declaring this function with external scope.
15300 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15302 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15303 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15305 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15307 * editfns.c (Fformat): Correctly handle text properties on "%%".

15316 (fill_composite_glyph_string): Add comments about special meaning
15317 of TAB characters in a composition.
15319 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15321 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15322 This occurs when processing a multibyte format.
15323 Problem reported by Wolfgang Jenker.
15325 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15327 * xdisp.c (try_cursor_movement): Only check for exact match if
15328 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15330 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15332 Remove unused external symbols.
15333 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15334 * xdisp.c (calc_pixel_width_or_height): Now static.
15335 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15336 * indent.c (check_display_width):
15337 * w32term.c: Fix comment to match code.
15338 * xterm.c, xterm.h (x_catching_errors): Remove.
15340 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15342 * xselect.c: Use signed conversions more consistently (Bug#9498).
15343 (selection_data_to_lisp_data): Assume incoming selection data are
15344 signed integers, not unsigned. This is to be consistent with
15345 outgoing selection data, which was modified to use signed integers
15346 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15347 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15348 expects long, not unsigned long.
15350 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15352 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15353 computation of loop end. Reported by Johan Bockgård
15356 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15358 * frame.c (Fother_visible_frames_p): Function deleted.
15360 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15362 * indent.c (compute_motion): Process display vector front to back
15363 rather than the other way around. (Bug#2496)
15365 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15367 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15369 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15371 * minibuf.c (Fread_from_minibuffer): Doc fix.
15373 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15375 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15376 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15378 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15380 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15381 value for non-existent files.
15383 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15385 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15386 set its "size" to -1. This will set the modtime_size field of
15387 the corresponding buffer to -1, which is what
15388 verify-visited-file-modtime expects for files that do not exist.
15391 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15393 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15395 * lisp.h: ... from here. push_key_description is no longer
15396 defined in keyboard.c, so its declaration should not be in
15397 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15398 logically belongs with push_key_description.
15400 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15402 * buffer.h: Include <sys/types.h> instead of <time.h>.
15403 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15404 Problem reported by Herbert J. Skuhra.
15406 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15408 * xml.c (parse_region): Make the parsing work for
15409 non-comment-starting XML files again (bug#9144).
15411 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15413 * image.c (gif_load): Fix calculation of bottom and right corner.
15416 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15418 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15419 redisplay in small windows.
15421 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15423 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15425 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15427 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15428 Operate on live windows only.
15430 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15432 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15434 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15436 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15437 only under bidi iteration.
15439 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15441 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15443 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15445 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15446 Without this fix, the command to link temacs failed due to an
15447 undefined symbol __builtin_isnan. This is because
15448 /usr/include/iso/math_c99.h #defines isnan(x) to
15449 __builtin_isnan(x), but the bundled gcc, which identifies itself
15450 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15452 * floatfns.c (isnan): #undef, and then #define to a clone of
15454 (Fisnan): Always define, since it's always available now.
15455 (syms_of_floatfns): Always define isnan at the Lisp level.
15457 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15459 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15461 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15463 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15464 The previous code assumed that file offsets (off_t values) fit in
15465 EMACS_INT variables, which is not true on typical 32-bit hosts.
15466 The code messed up by falsely reporting buffer overflow in cases
15467 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15468 when "big" contains more than 2**29 bytes, even though this
15469 inserts just one byte and does not overflow the buffer.
15470 (Finsert_file_contents): Store file offsets as off_t
15471 values, not as EMACS_INT values. Check for overflow when
15472 converting between EMACS_INT and off_t. When checking for
15473 buffer overflow or for overlap, take the offsets into account.
15474 Don't use EMACS_INT for small values where int suffices.
15475 When checking for overlap, fix a typo: ZV was used where
15476 ZV_BYTE was intended.
15477 (Fwrite_region): Don't assume off_t fits into 'long'.
15478 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15480 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15482 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15484 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15486 sprintf-related integer and memory overflow issues (Bug#9412).
15488 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15489 (esprintf, exprintf, evxprintf): New functions.
15490 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15491 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15492 (modify_event_symbol): Do not assume that the length of
15493 name_alist_or_stem is safe to alloca and fits in int.
15494 (Fexecute_extended_command): Likewise for function name and binding.
15495 (Frecursion_depth): Wrap around reliably on integer overflow.
15496 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15497 since some callers pass EMACS_INT values.
15498 (Fsingle_key_description): Don't crash if symbol name contains more
15499 than MAX_ALLOCA bytes.
15500 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15501 (get_minibuffer): Arg is now EMACS_INT, not int.
15502 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15503 (esprintf, exprintf, evxprintf): New decls.
15504 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15506 * dbusbind.c (signature_cat): New function.
15507 (xd_signature, Fdbus_register_signal):
15508 Do not overrun buffer; instead, report string overflow.
15510 * dispnew.c (add_window_display_history): Don't overrun buffer.
15511 Truncate instead; this is OK since it's just a log.
15513 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15514 even if the time zone offset is outlandishly large.
15515 Don't mishandle offset == INT_MIN.
15517 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15518 when creating daemon; the previous buffer-overflow check was incorrect.
15520 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15521 which has the guts of the old verror function.
15523 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15524 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15526 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15527 (font_unparse_xlfd): Don't blindly alloca long strings.
15528 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15529 fits in int, when using sprintf. Use single snprintf to count
15530 length of string rather than counting it via multiple sprintfs;
15531 that's simpler and more reliable.
15532 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15533 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15534 sprintf, in case result does not fit in int.
15536 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15537 (fontset_from_font): Print it.
15539 * frame.c (tty_frame_count): Now printmax_t, not int.
15540 (make_terminal_frame, set_term_frame_name): Print it.
15541 (x_report_frame_params): In X, window IDs are unsigned long,
15542 not signed long, so print them as unsigned.
15543 (validate_x_resource_name): Check for implausibly long names,
15544 and don't assume name length fits in 'int'.
15545 (x_get_resource_string): Don't blindly alloca invocation name;
15546 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15549 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15550 (xg_check_special_colors, xg_set_geometry):
15551 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15553 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15554 Use esprintf, not sprintf, in case result does not fit in int.
15556 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15557 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15558 it as a large positive number.
15559 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15560 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15562 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15563 in case result does not fit in int.
15565 * print.c (float_to_string): Detect width overflow more reliably.
15566 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15567 buffer overrun. Don't assume list length fits in 'int'. Treat
15568 print length of 0 as 0, not as infinity; to be consistent with other
15569 uses of print length in this function. Don't overflow print length
15570 index. Don't assume hash table size fits in 'long', or that
15571 vectorlike size fits in 'unsigned long'.
15573 * process.c (make_process): Use printmax_t, not int, to format
15574 process-name gensyms.
15576 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15578 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15579 to avoid potential buffer overrun.
15581 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15582 if X resource line is longer than 512 bytes.
15584 * xfns.c (x_window): Make sprintf buffer a bit bigger
15585 to avoid potential buffer overrun.
15587 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15589 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15591 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15593 Integer overflow fixes for scrolling, etc.
15594 Without these, Emacs silently mishandles large integers sometimes.
15595 For example, "C-u 4294967297 M-x recenter" was treated as if
15596 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15598 * xdisp.c (try_window_id): Check Emacs fixnum range before
15599 converting to 'int'.
15601 * window.c (window_scroll_line_based, Frecenter):
15602 Check that an Emacs fixnum is in range before assigning it to 'int'.
15603 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15604 values converted from Emacs fixnums.
15605 (Frecenter): Don't wrap around a line count if it is out of 'int'
15606 range; instead, treat it as an extreme value.
15607 (Fset_window_configuration, compare_window_configurations):
15608 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15610 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15611 that can exceed INT_MAX. Check that EMACS_INT value is in range
15612 before assigning it to the (possibly-narrower) index.
15613 (match_limit): Don't assume that a fixnum can fit in 'int'.
15615 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15618 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15619 (Fvertical_motion): Don't wrap around LINES values that don't fit
15620 in 'int'. Instead, treat them as extreme values. This is good
15621 enough for windows, which can't have more than INT_MAX lines anyway.
15623 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15625 * Require libxml/parser.h to avoid compilation warning.
15627 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15629 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15630 since this reportedly can destroy thread storage.
15632 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15634 * syntax.c (find_defun_start): Update all cache variables if
15635 exiting early (Bug#9401).
15637 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15639 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15641 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15642 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15643 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15645 * term.c (tty_append_glyph): New function.
15646 (produce_stretch_glyph): Static function and its prototype deleted.
15648 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15651 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15653 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15654 when checking :margin (Bug#9390).
15655 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15656 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15657 so that the name doesn't mislead. All uses changed.
15659 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15661 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15664 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15666 * xdisp.c (move_it_to): Don't bail out early when reaching
15667 position beyond to_charpos, if we are scanning backwards.
15668 (move_it_vertically_backward): When DY == 0, make sure we get to
15669 the first character in the line after the newline.
15671 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15673 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15674 (ccl_driver): Do not generate an out-of-range pointer.
15675 (Fccl_execute_on_string): Remove unnecessary check for
15676 integer overflow, noted by Stefan Monnier in
15677 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15678 Remove a FIXME that didn't need fixing.
15679 Simplify the newly-introduced buffer reallocation code.
15681 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15683 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15685 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15687 Integer and memory overflow issues (Bug#9196).
15689 * doc.c (get_doc_string): Rework so that
15690 get_doc_string_buffer_size is the actual buffer size, rather than
15691 being 1 less than the actual buffer size; this makes xpalloc more
15694 * image.c (x_allocate_bitmap_record, cache_image):
15695 * xselect.c (Fx_register_dnd_atom):
15696 Simplify previous changes by using xpalloc.
15698 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15699 since either will do and ptrdiff_t is convenient with xpalloc.
15701 * charset.c (charset_table_size)
15702 (struct charset_sort_data.priority): Now ptrdiff_t.
15703 (charset_compare): Don't overflow if priorities differ greatly.
15704 (Fsort_charsets): Don't assume list length fits in int.
15705 Check for size-calculation overflow when allocating sort data.
15706 (syms_of_charset): Allocate an initial charset table that is
15707 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15709 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15711 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15712 The actual value is always <= INT_MAX, and leaving it unsigned made
15713 overflow checking harder.
15715 * dispextern.h (struct glyph_matrix.rows_allocated)
15716 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15717 with xpalloc. The values are still always <= INT_MAX.
15719 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15721 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15722 (SAFE_NALLOCA): New macro.
15724 * region-cache.c (struct boundary.pos, find_cache_boundary)
15725 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15726 (set_cache_region, invalidate_region_cache)
15727 (revalidate_region_cache, know_region_cache, region_cache_forward)
15728 (region_cache_backward, pp_cache):
15729 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15730 so that ptrdiff_t * can be passed to xpalloc.
15731 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15732 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15733 (pp_cache): Don't assume cache_len fits in int.
15734 * region-cache.h: Adjust extern decls to match.
15736 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15737 EMACS_INT, since either will do, for xpalloc.
15739 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15740 (xnmalloc, xnrealloc, xpalloc): New functions.
15742 * bidi.c (bidi_shelve_header_size): New constant.
15743 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15744 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15746 * bidi.c (bidi_cache_shrink):
15747 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15749 Don't update size of array until after memory allocation succeeds,
15750 because xmalloc/xrealloc may not return.
15751 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15752 now that we have proper integer overflow checking.
15753 (record_overlay_string, overlay_strings): Catch overflows when
15754 calculating size of overlay_str_buf.
15756 * callproc.c (Fcall_process): Check for size overflow when
15757 calculating size of args2.
15758 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15759 Normally we prefer signed values, but sticking with ptrdiff_t would
15760 require adding more-complicated checks.
15762 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15763 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15764 Redo buffer-overflow calculations to avoid integer overflow.
15765 Add a FIXME comment where memory seems to be over-allocated.
15767 * character.c (Fstring): Check for size-calculation overflow.
15769 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15770 unnecessary integer overflow. Check for size overflow.
15771 (encode_coding_object): Don't update size until xmalloc succeeds.
15773 * composite.c (get_composition_id): Check for overflow in glyph
15774 length calculations.
15776 Integer and memory overflow fixes for display code.
15777 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15778 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15779 (scrolling_window): Check for overflow in size calculations.

15783 (row_table_size): Now ptrdiff_t, not int.
15784 (scrolling_window): Avoid overflow in size calculations.
15785 Don't update size until allocation succeeds.
15786 * fns.c (concat): Check for overflow in size calculations.
15787 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15788 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15791 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15792 (get_doc_string): Check for size calculation overflow.
15793 Don't update size until allocation succeeds.
15794 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15795 EMACS_INT, where ptrdiff_t will do.
15796 (Fsubstitute_command_keys): Check for string overflow.
15798 * editfns.c (set_time_zone_rule): Don't assume environment length
15800 (message_length): Now ptrdiff_t, not int.
15801 (Fmessage_box): Don't update size until allocation succeeds.
15802 Don't assume message length fits in int.
15803 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15805 * emacs.c (main): Do not reallocate argv, since there is a null at
15806 the end that can be overwritten, and this way there's no need to
15807 worry about size-calculation overflow.
15808 (sort_args): Check for size-calculation overflow.
15810 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15812 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15814 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15815 (x_set_scroll_bar_width, x_figure_window_size):
15816 Check for integer overflow.
15817 (x_set_alpha): Do not assume XINT fits in int.
15819 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15820 This is for the members text_lines, text_cols, total_lines, total_cols,
15821 where the system imposes an 'int' limit.
15823 * fringe.c (Fdefine_fringe_bitmap):
15824 Don't update size until alloc works.
15826 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15827 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15829 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15830 Check for size-calculation overflow.
15831 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15832 do, as we prefer signed integers.
15833 (id_to_widget.max_size, id_to_widget.used)
15834 (xg_store_widget_in_map, xg_remove_widget_from_map)
15835 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15836 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15837 Use and return ptrdiff_t, not int.
15838 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15839 * gtkutil.h: Change prototypes to match the above.
15841 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15842 are duplicate now that they've been promoted to lisp.h.
15843 (x_allocate_bitmap_record, x_alloc_image_color)
15844 (make_image_cache, cache_image, xpm_load):
15845 Don't update size until alloc is done.
15846 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15848 Check for size calculation overflow.
15849 (ct_colors_allocated_max): New constant.
15850 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15853 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15854 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15855 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15856 Use ptrdiff_t, not int, to count maps.
15857 (read_char_minibuf_menu_prompt): Check for overflow in size
15858 calculations. Don't update size until allocation succeeds.
15859 Redo calculations to avoid overflow.
15860 * keyboard.h: Change prototypes to match the above.
15862 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15864 (current_minor_maps): Check for size calculation overflow.
15865 * keymap.h: Change prototypes to match the above.
15867 * lread.c (read1, init_obarray): Don't update size until alloc done.
15869 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15870 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15872 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15873 Now ptrdiff_t, not int.
15874 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15880 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15882 * scroll.c (do_line_insertion_deletion_costs): Check for size calc

15886 (Fset_match_data): Don't assume list lengths fit in 'int'.
15888 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15889 for command line length. Do not attempt to address one before the
15890 beginning of an array, as that's not portable.
15892 * term.c (max_frame_lines): Remove; unused.
15893 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15895 (encode_terminal_code, calculate_costs): Check for size
15896 calculation overflow.

15899 done. Redo calculations to avoid overflow.
15900 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15902 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15903 subtracting pointers.
15904 (gobble_line): Check for overflow more carefully. Don't update size
15907 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15908 Don't update size until alloc done.

15918 Use ptrdiff_t, not int, for sizes.
15919 (Finternal_make_lisp_face, cache_face):
15920 Check for size calculation overflow.
15921 (cache_face): Treat size calculation overflows as if they were
15922 memory exhaustion (the usual treatment), rather than aborting.
15924 * xfns.c (x_encode_text, x_set_name_internal)
15925 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15926 sizes, since they can exceed INT_MAX in size. Check for size
15927 calculation overflow.
15929 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15930 (xg_select): Check for size calculation overflow.
15931 Don't update size until alloc done.
15933 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15934 as sprintf is limited to int lengths.
15936 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15937 (X_LONG_MIN): New macros.
15938 Use them to make the following changes clearer.
15939 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15940 This change doesn't affect the value now, but it may help remind
15941 future maintainers not to raise the value too much later.
15942 (SELECTION_QUANTUM): Remove, replacing with ...
15943 (selection_quantum): ... new function, which avoids overflow.
15945 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15946 assumption that selection length fits in 'int'.
15947 (x_reply_selection_request, x_handle_selection_request)
15948 (x_get_window_property, receive_incremental_selection)
15949 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15950 (lisp_data_to_selection_data, clean_local_selection_data):

15952 (x_reply_selection_request, x_get_window_property)
15953 (receive_incremental_selection, x_property_data_to_lisp):
15954 Redo calculations to avoid overflow.
15955 (x_reply_selection_request): When sending hint, ceiling it at
15956 X_LONG_MAX rather than relying on wraparound overflow to send
15958 (x_get_window_property, receive_incremental_selection)
15959 (lisp_data_to_selection_data, x_property_data_to_lisp):
15960 Check for size-calculation overflow.
15961 (x_get_window_property, receive_incremental_selection)
15962 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15963 Don't store size until memory allocation succeeds.
15964 (x_get_window_property): Plug memory leak on memory exhaustion.
15965 Don't double-block input; malloc is safe here. Don't assume 2**34
15966 - 4 fits in unsigned long. Add an xassert to check
15967 XGetWindowProperty overflow. Be more careful about overflow
15968 calculations, and distinguish size from memory overflow better.
15969 (receive_incremental_selection): When tracing, don't assume
15970 unsigned int is less than INT_MAX.
15971 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15972 harmful) conversions of unsigned short to int.
15973 (lisp_data_to_selection_data): Don't assume that integers
15974 in the range -65535 through -1 fit in an X unsigned short.
15975 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15976 result parameters unless successful. Rely on cons_to_unsigned
15977 to report problems with elements; the old code wasn't right anyway.
15978 (x_check_property_data): Check for int overflow; we cannot use
15979 a wider type due to X limits.
15980 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15982 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

16011 * image.c (xpm_get_color_table_h):
16012 * lisp.h (hash_lookup, hash_put):
16013 * minibuf.c (Ftest_completion):
16014 Use ptrdiff_t for hash table indexes, not int (which is too
16015 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16016 32-bit --with-wide-int hosts).
16018 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16019 Add a FIXME comment about memory leaks.
16020 (syms_of_charset): Don't assume xmalloc returns.
16022 Don't assume that stated character widths fit in int.
16023 * character.c (Fchar_width, c_string_width, lisp_string_width):
16024 * character.h (CHAR_WIDTH):
16025 * indent.c (MULTIBYTE_BYTES_WIDTH):
16026 Use sanitize_char_width to avoid undefined and/or bad behavior
16027 with outlandish widths.
16028 * character.h (sanitize_tab_width): Rename from sanitize_width,
16029 now that we have two such functions. All uses changed.
16030 (sanitize_char_width): New inline function.
16032 Don't assume that tab-width fits in int.
16033 * character.h (sanitize_width): New inline function.
16034 (SANE_TAB_WIDTH): New macro.
16035 (ASCII_CHAR_WIDTH): Use it.

16040 * fileio.c: Integer overflow issues with file modes.
16041 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16043 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16044 Remove unreachable code.
16045 (read_hex, load_charset_map_from_file): Check for integer overflow.
16047 * xterm.c: Don't go over XClientMessageEvent limit.
16048 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16049 (x_send_scroll_bar_event): Likewise. Check that the size does not
16050 exceed limits imposed by XClientMessageEvent, as well as the usual
16051 ptrdiff_t and size_t limits.
16053 * keyboard.c: Overflow, signedness and related fixes.
16054 (make_lispy_movement): Use same integer type in forward decl
16055 that is used in the definition.
16056 (read_key_sequence, keyremap_step):
16057 Change bufsize argument back to int, undoing my 2011-03-30 change.
16058 We prefer signed types, and int is wide enough here.
16059 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16060 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16061 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16062 length, not size_t. Use ptrdiff_t for index, not int.
16063 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16064 possibility of integer overflow.
16066 Overflow, signedness and related fixes for images.

16076 * xdisp.c (calc_pixel_width_or_height):
16077 * xfns.c (image_cache_refcount):
16078 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16079 on typical 64-bit hosts.

16085 when the callers expect that.
16086 (image_ascent): Redo ascent calculation to avoid int overflow.
16087 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16088 (lookup_image): Remove unnecessary tests.
16089 (xbm_image_p): Locals are now of int, not EMACS_INT,
16090 since parse_image_check makes sure they fit into int.
16091 (png_load, gif_load, svg_load_image):
16092 Prefer int to unsigned where either will do.
16093 (tiff_handler): New function, combining the cores of the
16094 old tiff_error_handler and tiff_warning_handler.
16095 This function is rewritten to use vsnprintf and thereby avoid
16096 stack buffer overflows. It uses only the features of vsnprintf
16097 that are common to both POSIX and native Microsoft.
16098 (tiff_error_handler, tiff_warning_handler): Use it.
16099 (tiff_load, gif_load, imagemagick_load_image):
16100 Don't assume :index value fits in 'int'.
16101 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16102 (imagemagick_load_image): Check that crop parameters fit into
16103 the integer types that MagickCropImage accepts. Don't assume
16104 Vimagemagick_render_type has a nonnegative value. Don't assume
16105 size_t fits in 'long'.
16106 (gs_load): Use printmax_t to print the widest integers possible.
16107 Check for integer overflow when computing image height and width.

16116 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16117 the display spec is of the form `(space ...)'.
16118 (handle_display_spec): Return the value returned by
16119 handle_single_display_spec, not just 1 or zero.
16120 (handle_single_display_spec): If the display spec is of the form
16121 `(space ...)', and specifies display in the text area, return 2
16123 (try_cursor_movement): Check for the need to scroll more
16124 accurately, and prefer exact match for point under bidi.
16125 Don't advance `row' beyond the last row of the window.
16127 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16128 into disp_prop; all users changed.
16130 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16131 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16132 for the text covered by the display property.

16142 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16143 buffers, return left-to-right.
16144 (set_cursor_from_row): Consider candidate row a win if its glyph
16145 represents a newline and point is on that newline. Fixes cursor
16146 positioning on the newline at EOL of R2L text within L2R
16147 paragraph, and vice versa.
16148 (try_cursor_movement): Check continued rows, in addition to
16149 continuation rows. Fixes unwarranted scroll when point enters a
16150 continued line of R2L text within an L2R paragraph, or vice versa.
16151 (cursor_row_p): Consider the case of point being equal to
16152 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16153 from the end of a short line to the beginning of a continued line
16154 of R2L text within L2R paragraph.
16155 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16156 composed characters.

16171 2011-08-22 Kenichi Handa <handa@m17n.org>
16173 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16174 extra slot even if the purpose is char-code-property-table.
16176 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16178 * xdisp.c (redisplay_window): When computing centering_position,
16179 account for the height of the header line. (Bug#8874)
16181 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16182 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16183 candidate is selected by the mouse, and that candidate has a
16184 composed character under the mouse.
16186 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16187 coordinates reported by pos-visible-in-window-p for a composed
16188 character in column zero.
16190 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16192 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16194 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16196 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16197 consider it a hit if to_charpos is anywhere in the range of the
16198 composed buffer positions.
16200 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16202 * image.c (gif_load): Don't assume that each subimage has the same
16203 dimensions as the base image. Handle disposal method that is
16204 "undefined" by the gif spec (Bug#9335).
16206 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16208 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16211 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16213 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16214 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16215 from an Org mode buffer to a Speedbar frame.
16217 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16218 a composition, take its buffer position from IT->cmp_it.charpos.
16219 Fixes cursor positioning at the beginning of a line that begins
16220 with a composed character.
16222 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16224 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16225 character bidirectional type, use STRONG_L instead. Fixes crashes
16226 in a buffer produced by `describe-categories'.
16228 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16229 members before the level stack, so they would be saved and
16230 restored when copying iterator state. Fixes incorrect reordering
16231 around TABs covered by display properties.
16233 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16235 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16240 (internal_condition_case_2, internal_condition_case_n):
16241 Remove unnecessary aborts (Bug#9081).
16243 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16245 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16246 has no `load' handler, try opening the file locally. (Bug#9311)
16248 2011-08-16 Ken Brown <kbrown@cornell.edu>
16250 * gmalloc.c: Expand comment.
16252 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16254 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16255 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

16300 * process.c (create_process): Call setup_process_coding_systems
16301 after the pid of the process is set to -1 (Bug#8162).
16303 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16305 * xdisp.c (move_it_in_display_line_to): Don't invoke
16306 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16307 ppos_it. Fixes vertical cursor motion when line beginning is
16308 covered by an image. (Bug#9296)
16310 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16312 * nsterm.h (ns_run_ascript): Declare.

16316 (ns_run_ascript): New function.
16317 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16318 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16319 the event loop. Get status from as_status (Bug#7276).
16321 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16322 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16323 the event loop (Bug#7276).
16325 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

16348 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16349 (Fnetwork_interface_list): Allocate in increments of bytes instead
16350 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16351 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16353 (struct ifflag_def): notrailers is smart on OSX.
16354 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16355 Get hardware address with getifaddrs if available.
16357 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16359 * xdisp.c (iterate_out_of_display_property): xassert that
16360 IT->position is set to within IT->object's boundaries. Break from
16361 the loop as soon as EOB is reached; avoids infloops in redisplay
16362 when IT->position is set up wrongly due to some bug.
16363 Set IT->current to match the bidi iterator unconditionally.
16364 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16365 entry. Force push_it to save on the stack the current
16366 buffer/string position, to be restored by pop_it. Fix flags in
16367 the iterator structure wrt the object coming from a display
16368 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16369 properties. (Bug#9284)
16371 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16373 * fontset.c (fontset_get_font_group): Add proper type checks.

16386 no-display-properties-and-no-overlays under bidi display.
16387 Set disp_pos in the bidi iterator to avoid searches for display
16388 properties and overlays.
16390 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16392 * editfns.c (Fset_time_zone_rule): Document relationship with the

16398 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16400 * composite.c (autocmp_chars): Don't reset point. That is done by
16401 restore_point_unwind (Bug#5984).
16403 2011-08-07 Juri Linkov <juri@jurta.org>
16405 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16406 to show the arg `TIME' instead of `TIMEVAL'.
16408 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16410 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16411 display property strides EOL and includes a newline, as in
16412 longlines-mode. (Bug#9254)
16413 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16414 word-wrap under bidirectional display. (Bug#9224)
16416 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16417 is non-zero, even if the data buffer is NULL. Fixes a crash in
16418 vertical-motion with longlines-mode. (Bug#9254)
16420 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16422 * bidi.c <bidi_cache_total_alloc>: Now static.
16423 (bidi_initialize): Initialize bidi_cache_total_alloc.
16425 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16428 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16429 amount allocated this far in `bidi_cache_total_alloc'.
16430 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16431 non-zero, only free the data buffer without restoring the cache
16432 contents. All callers changed.
16434 * dispextern.h (bidi_unshelve_cache): Update prototype.
16436 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16437 (move_it_in_display_line, move_it_to)
16438 (move_it_vertically_backward, move_it_by_lines): Replace the call
16439 to xfree to an equivalent call to bidi_unshelve_cache.
16440 (move_it_in_display_line_to): Fix logic of returning
16441 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16443 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16445 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16446 came from a string character with a `cursor' property. (Bug#9229)
16448 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16450 * Makefile.in (LIB_PTHREAD): New variable.
16451 (LIBES): Add LIB_PTHREAD (Bug#9216).
16453 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

16460 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16462 * xterm.c (x_find_topmost_parent): New function.
16463 (x_set_frame_alpha): Find topmost parent window with
16464 x_find_topmost_parent and set the property there also (bug#9181).
16465 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16467 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16469 * callproc.c (Fcall_process): Avoid vfork clobbering
16470 the local vars buffer, coding_systems, current_dir.
16472 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16474 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16476 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16478 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16479 so that it is not optimized away.
16481 * xdisp.c (compute_display_string_pos): Remove unused local.
16483 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16485 Fix slow cursor motion and scrolling in large buffers with
16486 selective display, like Org Mode buffers. (Bug#9218)
16488 * dispextern.h (struct bidi_it): New member disp_prop_p.
16490 * xdisp.c: Remove one-slot cache of display string positions.
16491 (compute_display_string_pos): Accept an additional argument
16492 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16493 for a display string or property. If found, set DISP_PROP_P
16496 * bidi.c (bidi_fetch_char): Accept an additional argument
16497 DISP_PROP_P, and pass it to compute_display_string_pos.
16498 Only handle text covered by a display string if DISP_PROP_P is returned
16499 non-zero. All callers of bidi_fetch_char changed.
16501 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16503 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16505 2010-12-03 Don March <don@ohspite.net>
16507 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16508 last character M-[char] is translated to ESC [char] (bug#7541).
16510 2011-08-02 Kenichi Handa <handa@m17n.org>
16512 * lisp.h (uniprop_table): Extern it.
16514 * chartab.c (uniprop_table): Make it non-static.
16516 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16518 * xdisp.c (forward_to_next_line_start): Accept additional argument
16519 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16521 (reseat_at_next_visible_line_start): Use the bidi iterator state
16522 returned by forward_to_next_line_start to restore the state of
16523 it->bidi_it after backing up to previous newline. (Bug#9212)
16525 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16527 * regex.c (re_comp): Protoize.
16528 (re_exec): Fix return type.
16529 (regexec): Fix type of `ret'. (Bug#9203)
16531 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16533 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16534 This is needed if max-image-size is a floating-point number.
16536 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16538 * print.c (print_object): Print empty symbol as ##.
16540 * lread.c (read1): Read ## as empty symbol.
16542 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16544 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16545 setting frame foreground color (Bug#9175).
16546 (x_set_background_color): Likewise.
16548 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16549 contents (Bug#9176).
16550 (EmacsTooltip -init): Remove bezels and add shadows to
16553 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16554 or scroll bar (Bug#8470).
16556 * nsfont.m (nsfont_open): Remove assignment to voffset and
16557 unnecessary vars hshink, expand, hd, full_height, min_height.
16558 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16560 * nsterm.h (nsfont_info): Remove voffset field.
16562 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16564 Implement strike-through and overline on NextStep (Bug#8863).
16566 * nsfont.m (nsfont_open): Use underline position provided by font,
16567 instead of hard-coded value of 2.
16568 (nsfont_draw): Call ns_draw_text_decoration instead.
16570 * nsterm.h: Add declaration for ns_draw_text_decoration.
16572 * nsterm.m (ns_draw_text_decoration): New function for drawing
16573 underline, overline, and strike-through.
16574 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16575 ns_draw_text_decoration. Change treatment of cursor drawing to
16576 accommodate underlining, etc.
16578 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16580 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16583 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16585 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16586 Without this fix, if a signal arrives just after memory fills up,
16587 'malloc' might be invoked reentrantly.
16589 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16590 In other words, assume that every image size is allowed, on non-X
16591 hosts. This assumption is probably wrong, but it lets Emacs compile.
16593 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16595 * regex.c (re_iswctype): Convert return values to boolean.
16597 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16599 * xdisp.c (compute_display_string_pos): Don't use cached display
16600 string position if the buffer had its restriction changed.
16603 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16605 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16607 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16609 Integer signedness and overflow and related fixes. (Bug#9079)
16611 * bidi.c: Integer size and overflow fixes.
16612 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16613 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16614 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16615 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16616 (bidi_find_other_level_edge):
16617 Use ptrdiff_t instead of EMACS_INT where either will do.
16618 This works better on 32-bit hosts configured --with-wide-int.
16619 (bidi_cache_ensure_space): Check for size-calculation overflow.
16620 Use % rather than repeated addition, for better worst-case speed.
16621 Don't set bidi_cache_size until after xrealloc returns, because it
16623 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16624 (bidi_cache_ensure_space): Also check that the bidi cache size
16625 does not exceed that of the largest Lisp string or buffer. See Eli
16626 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16628 * alloc.c (__malloc_size_t): Remove.
16629 All uses replaced by size_t. See Andreas Schwab's note
16630 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16632 * image.c: Improve checking for integer overflow.
16633 (check_image_size): Assume that f is nonnull, since
16634 it is always nonnull in practice. This is one less thing to
16635 worry about when checking for integer overflow later.
16636 (x_check_image_size): New function, which checks for integer
16637 overflow issues inside X.
16638 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16639 This removes the need for a memory_full check.
16640 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16641 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16642 (xbm_read_bitmap_data): Change locals back to 'int', since
16643 their values must fit in 'int'.
16644 (xpm_load_image, png_load, tiff_load):
16645 Invoke x_create_x_image_and_pixmap earlier,
16646 to avoid much needless work if the image is too large.
16647 (tiff_load): Treat overly large images as if
16648 x_create_x_image_and_pixmap failed, not as malloc failures.
16649 (gs_load): Use x_check_image_size.
16651 * gtkutil.c: Omit integer casts.
16652 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16653 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16655 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16657 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16658 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16659 would wrongly return t on a 64-bit host.
16661 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16662 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16663 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16664 and therefore cause GCC to emit a bogus diagnostic in some cases.
16666 * image.c: Integer signedness and overflow and related fixes.
16667 This is not an exhaustive set of fixes, but it's time to
16668 record what I've got.
16669 (lookup_pixel_color, check_image_size): Remove redundant decls.
16670 (check_image_size): Don't assume that arbitrary EMACS_INT values
16671 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16672 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16673 (tiff_load, imagemagick_load_image):
16674 Check for overflow in size calculations.
16675 (x_create_x_image_and_pixmap): Remove unnecessary test for
16676 xmalloc returning NULL; that can't happen.
16677 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16678 (xpm_color_bucket): Use better integer hashing function.
16679 (xpm_cache_color): Don't possibly over-allocate memory.
16680 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16681 (gif_memory_source):
16682 Use ptrdiff_t, not int or size_t, to record sizes.
16683 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16684 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16685 either works, as we prefer signed integers.
16686 (tiff_read_from_memory, tiff_write_from_memory):
16687 Return tsize_t, not size_t, since that's what the TIFF API wants.
16688 (tiff_read_from_memory): Don't fail simply because the read would
16689 go past EOF; instead, return a short read.
16690 (tiff_load): Omit no-longer-needed casts.
16691 (Fimagemagick_types): Don't assume size fits into 'int'.
16693 Improve hashing quality when configured --with-wide-int.
16694 * fns.c (hash_string): New function, taken from sxhash_string.
16695 Do not discard information about ASCII character case; this
16696 discarding is no longer needed.
16697 (sxhash-string): Use it. Change sig to match it. Caller changed.
16698 * lisp.h: Declare it.
16699 * lread.c (hash_string): Remove, since we now use fns.c's version.
16700 The fns.c version returns a wider integer if --with-wide-int is
16701 specified, so this should help the quality of the hashing a bit.
16703 * emacs.c: Integer overflow minor fix.
16704 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16705 Define only if GNU_LINUX.
16706 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16708 * dispnew.c: Integer signedness and overflow fixes.
16709 Remove unnecessary forward decls, that were a maintenance hassle.
16710 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16712 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16713 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16714 (prepare_desired_row, line_draw_cost):
16715 Use int, not unsigned, where either works.
16716 (save_current_matrix, restore_current_matrix):
16717 Use ptrdiff_t, not size_t, where either works.
16718 (init_display): Check for overflow more accurately, and without
16719 relying on undefined behavior.
16721 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16722 Remove, replacing with the new symbols in lisp.h. All uses changed.
16723 * fileio.c (make_temp_name):
16724 * filelock.c (lock_file_1, lock_file):
16725 * xdisp.c (message_dolog):
16726 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16727 Use pMd etc. instead.
16728 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16729 replacing the pWIDE etc. symbols removed from editfns.c.
16731 * keyboard.h (num_input_events): Now uintmax_t.
16732 This is (very slightly) less likely to mess up due to wraparound.
16735 * buffer.c: Integer signedness fixes.
16736 (alloc_buffer_text, enlarge_buffer_text):
16737 Use ptrdiff_t rather than size_t when either will do, as we prefer
16740 * alloc.c: Integer signedness and overflow fixes.
16741 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16742 (__malloc_size_t): Default to size_t, not to int.
16743 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16744 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16745 Prefer ptrdiff_t to size_t when either would do, as we prefer
16747 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16748 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16749 Now const. Initialize with values that are in range even if char
16751 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16752 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16753 These functions do the right thing with sizes > 2**32.
16754 (check_depth): Now ptrdiff_t, not int.
16755 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16756 Adjust to new way of storing sizes. Check for size overflow bugs
16758 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16759 slightly wrong anyway, as it missed one instance of
16760 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16761 (refill_memory_reserve): Omit needless cast to size_t.
16762 (mark_object_loop_halt): Mark as externally visible.
16764 * xselect.c: Integer signedness and overflow fixes.
16765 (Fx_register_dnd_atom, x_handle_dnd_message):
16766 Use ptrdiff_t, not size_t, since we prefer signed.
16767 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16768 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16769 x_dnd_atoms_size and x_dnd_atoms_length.
16771 * doprnt.c: Prefer signed to unsigned when either works.
16773 * doprnt.c (doprnt):
16775 * xdisp.c (vmessage):
16776 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16777 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16778 prefer signed arithmetic to avoid comparison confusion.
16779 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16780 but is a bit tricky.
16782 Assume freestanding C89 headers, string.h, stdlib.h.
16783 * data.c, doprnt.c, floatfns.c, print.c:
16784 Include float.h unconditionally.
16785 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16786 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16787 * regex.c: Likewise for stddef.h, string.h.
16788 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16789 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16790 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16791 (STDC_HEADERS): Remove obsolete defines.
16792 * sysdep.c: Include limits.h unconditionally.
16794 Assume support for memcmp, memcpy, memmove, memset.
16795 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16796 * regex.c (memcmp, memcpy):
16797 Remove; we assume C89 now.
16799 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16800 (__malloc_safe_bcopy): Remove; no longer needed.
16802 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16803 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16804 well either way, and we prefer signed to unsigned.
16806 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16808 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16809 closes the connection while we're reading (bug#9182).
16811 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16813 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16814 are specified (Bug#9168).
16816 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16818 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16819 Found by GCC static checking and --with-wide-int on a 32-bit host.
16821 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16823 * xdisp.c (compute_display_string_pos): Fix logic of caching
16824 previous display string position. Initialize cached_prev_pos to
16825 -1. Fixes slow-down at the beginning of a buffer.
16827 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16829 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16830 for attrs[LFACE_FONTSET_INDEX].
16832 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16834 * xml.c (parse_region): Remove unused local
16835 that was recently introduced.
16837 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16839 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16840 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16842 * xdisp.c (move_it_in_display_line_to): Record the best matching
16843 position for TO_CHARPOS while scanning the line, and restore it on
16844 exit if none of the characters scanned was an exact match.
16845 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16846 when exact match is impossible due to invisible text, and the
16847 lines are truncated.
16849 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16851 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16854 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16856 Fix a significant slow-down of cursor motion with C-n, C-p,
16857 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16858 auto-repeat under bidi redisplay in fontified buffers.
16859 * xdisp.c (compute_stop_pos_backwards): New function.
16860 (next_element_from_buffer): Call compute_stop_pos_backwards to
16861 find a suitable prev_stop when we find ourselves before
16863 (reseat): Don't look for prev_stop, as that could mean a very long
16865 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16866 <cached_disp_overlay_modiff>: Cache for last found display string
16868 (compute_display_string_pos): Return the cached position if asked
16869 about the same buffer in the same area of character positions, and
16870 the buffer wasn't changed since the time the display string
16871 position was cached.
16873 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16875 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16876 is an integer, which is important for empty lines. (Bug#9149)
16878 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16880 * frame.c (Fmodify_frame_parameters): In tty case, update the
16881 default face if necessary (Bug#4238).
16883 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16885 * editfns.c (Fstring_to_char): No need to explain what a character
16886 is in the docstring (Bug#6576).
16888 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16890 * xml.c (parse_region): Make sure we always return a tree.
16892 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16894 * xml.c (parse_region): If a document contains only comments,
16897 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16899 * xml.c (make_dom): Return comments, too.
16901 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16904 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16905 and the surrounding thread.
16906 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16907 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16908 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16910 * s/openbsd.h (BROKEN_SIGIO): Define.
16911 * unexelf.c (unexec) [__OpenBSD__]:
16912 Don't update the .mdebug section of the Alpha COFF symbol table.
16914 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16916 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16919 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16921 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16922 This fixes some race conditions on the permissions of any newly
16925 * alloc.c (valid_pointer_p): Use pipe, not open.
16926 This fixes some permissions issues when debugging.
16928 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16929 If fchown fails to set both uid and gid, try to set just gid,
16930 as that is sometimes allowed. Adjust the file's mode to eliminate
16931 setuid or setgid bits that are inappropriate if fchown fails.
16933 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16935 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16936 to compare Lisp_Objects.

16941 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16943 * lread.c (read_integer): Unread even EOF character.
16944 (read1): Likewise. Properly record start position of symbol.

16947 symbol character follows.
16949 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16951 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16952 This works around a problem with the previous change to Fcopy_file.
16953 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16954 and without this change, GCC might complain about discarding
16955 fchown's return value.
16957 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16959 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16961 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16963 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16965 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16967 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16968 it's used from the C level.
16970 * process.c: Use the same condition for POLL_FOR_INPUT in both
16971 keyboard.c and process.c (bug#1858).
16973 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16975 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16976 (Fgnutls_boot): Use it.
16978 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16980 * doc.c (Fsubstitute_command_keys): Revert last change.
16982 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16984 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16985 quotes the next character, and doesn't affect other longer
16986 sequences (bug#8935).
16988 * lread.c (syms_of_lread): Clarify that is isn't only
16989 `eval-buffer' and `eval-defun' that's affected by
16990 `lexical-binding' (bug#8460).
16992 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16994 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16995 bidi redisplay when a line includes both an image and is truncated.
16997 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16999 Fix minor problems found by static checking.
17000 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17001 (elsz): Now a signed constant, not a size_t var. We prefer signed
17002 types to unsigned, to avoid integer comparison confusion. Without
17003 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17004 "cannot optimize loop, the loop counter may overflow", a symptom
17006 * indent.c (Fvertical_motion): Mark locals as initialized.
17007 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17009 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17011 * search.c (Fre_search_backward): Mention `case-fold-search' in
17012 all the re_search_* functions (bug#8138).
17014 * keyboard.c (Fopen_dribble_file): Document when the file is

17035 (display_string): If we need to ignore text properties of
17036 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17037 original value of -1 will not work with bidi.)
17038 (compute_display_string_pos): First arg is now struct
17039 `text_pos *'; all callers changed. Support display properties on
17041 (compute_display_string_end): Support display properties on Lisp
17043 (init_iterator, reseat_1, reseat_to_string): Initialize the
17044 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17045 when iterating on a string not from display properties).
17046 (compute_display_string_pos, compute_display_string_end):
17047 Fix calculation of the object to scan. Fixes an error when using
17049 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17050 base_level_stop; instead, set base_level_stop to BEGV.
17051 Fixes crashes in vertical-motion.
17052 (next_element_from_buffer): Improve commentary for when
17053 the iterator is before prev_stop.
17054 (init_iterator): Initialize bidi_p from the default value of

17066 (init_iterator): Don't initialize it->bidi_p for strings
17068 (reseat_to_string): Initialize it->bidi_p for strings here.

17077 parts of next_element_from_buffer, next_element_from_string, and
17078 next_element_from_c_string.
17079 (tool_bar_lines_needed, redisplay_tool_bar)
17080 (display_menu_bar): Force left-to-right direction. Add a FIXME

17091 iterator for displaying display or overlay strings.
17092 (forward_to_next_line_start): Don't use the shortcut if
17094 (back_to_previous_visible_line_start): If handle_display_prop
17095 pushed the iterator stack, restore the internal state of the bidi
17096 iterator by calling bidi_pop_it same number of times.
17097 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17098 and we are bidi-iterating, don't decrement the iterator position;
17099 instead, set the first_elt flag in the bidi iterator, to produce
17101 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17102 (push_display_prop): xassert that we are iterating a buffer.

17106 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17107 correctly. Don't assume unibyte strings are not bidi-reordered.

17116 property. Fix a typo in popping stretch info. Add an assertion
17117 for verifying that the iterator position is in sync with the bidi
17119 (handle_single_display_spec, get_overlay_strings_1)

17209 (struct iterator_stack_entry): New members bidi_p,
17210 paragraph_embedding, and from_disp_prop_p.

17264 The old code sometimes used this field without initializing it.
17266 * alloc.c (gc_sweep): Don't read past end of array.

17531 (clone_per_buffer_values): Don't assume that
17532 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
17533 This isn't true in general, and it's particularly not true
17534 if Emacs is configured with --with-wide-int.
17535 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17536 New macros, used in the buffer.c change.

17572 Random fixes. E.g., (random) never returned negative values.
17573 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17574 subseconds part to the entropy, as that's a bit more random.
17575 Prefer signed to unsigned, since the signedness doesn't matter and
17576 in general we prefer signed. When given a limit, use a
17577 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17578 latter isn't right if USE_2_TAGS_FOR_INTS.
17579 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17580 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17592 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17593 This is more efficient than Ffile_directory_p and avoids a minor race.
17595 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17597 * buffer.c (Foverlay_put): Say what the return value is
17600 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17601 is a directory before asking whether to use the file name

17604 error be more correct.
17606 * fns.c (Frequire): Remove the mention of the .gz files, since
17607 that's installation-specific, but keep the mention of
17608 `get-load-suffixes'.

17612 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17620 Qgnutls_bootprop_verify_error (which is no longer used).
17622 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17623 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17624 Also (re)move comments that are misplaced or no longer relevant.

17651 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
17653 * lread.c (syms_of_lread): Mention single symbols defined by
17654 `defvar' or `defconst' (bug#7154).
17656 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17657 (Frequire): Mention get-load-suffixes.

17725 * eval.c (struct backtrace): Simplify and port the data structure.
17726 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17727 signed bit field, as this assumption is not portable and it makes
17728 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17729 "char debug_on_exit : 1" as this is not portable either; instead,
17730 use the portable "unsigned int debug_on_exit : 1". Remove unused
17731 member evalargs. Remove obsolete comments about cc bombing out.
17733 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17815 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
17816 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
17819 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
17821 * process.c (wait_reading_process_output): Bypass select if
17822 waiting for a cell while ignoring keyboard input, and input is
17823 pending. Suggested by Jan Djärv (Bug#8869).
17825 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
17827 Use gnulib's dup2 module instead of rolling our own.
17828 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17897 Integer and buffer overflow fixes (Bug#8873).
17899 * print.c (printchar, strout): Check for string overflow.
17900 (PRINTPREPARE, printchar, strout):
17901 Don't set size unless allocation succeeds.
17903 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17904 for sizes. Check for string overflow more accurately.
17905 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17907 * macros.c: Integer and buffer overflow fixes.
17908 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17909 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17913 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17915 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17917 * lread.c: Integer overflow fixes.
17918 (read_integer): Radix is now EMACS_INT, not int,
17919 to improve quality of diagnostics for out-of-range radices.
17920 Calculate buffer size correctly for out-of-range radices.
17921 (read1): Check for integer overflow in radices, and in
17922 read-circle numbers.
17923 (read_escape): Avoid int overflow.
17924 (Fload, openp, read_buffer_size, read1)
17925 (substitute_object_recurse, read_vector, read_list, map_obarray):

17941 2011-06-22 Leo Liu <sdl.web@gmail.com>
17943 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17944 Move to minibuffer.el.
17946 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17948 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17949 The following patches are for when GLYPH_DEBUG && !XASSERT.
17950 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17951 * dispnew.c (flush_stdout):
17952 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17953 Mark as externally visible.
17954 * dispnew.c (check_window_matrix_pointers): Now static.
17955 * dispnew.c (window_to_frame_vpos):
17956 * xfns.c (unwind_create_frame):
17957 * xterm.c (x_check_font): Remove unused local.
17958 * scroll.c (CHECK_BOUNDS):
17959 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17960 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17961 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17962 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17963 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17965 (debug_method_add): Use va_list and vsprintf rather than relying
17966 on undefined behavior with wrong number of arguments.
17967 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17968 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17969 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17970 since we're not interested in debugging glyphs with old libraries.
17971 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17972 GCC 4.6.0's static checking.
17974 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17976 Integer overflow and signedness fixes (Bug#8873).

17992 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17993 (.bitmaps_last, struct x_output.icon_bitmap):
17994 Use ptrdiff_t, not int, for bitmap indexes.
17995 (x_allocate_bitmap_record): Check for size overflow.
17996 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17998 Use ptrdiff_t, not int, for overlay counts.
17999 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18000 * editfns.c (overlays_around, get_pos_property):

18002 * xdisp.c (next_overlay_change, note_mouse_highlight):
18003 * xfaces.c (face_at_buffer_position):
18004 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18005 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18006 (Fnext_overlay_change, Fprevious_overlay_change)
18007 (mouse_face_overlay_overlaps, Foverlays_in):
18008 Use ptrdiff_t, not int, for sizes.
18009 (overlays_at, overlays_in): Check for size-calculation overflow.
18011 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18013 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18014 (x_session_initialize): Do not assume string length fits in int.
18016 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18017 This is unlikely, but can occur if DPI is outlandish.
18019 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18020 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

18023 * xrdb.c (magic_file_p, search_magic_path):
18024 Omit last arg SUFFIX; it was always 0. All callers changed.
18025 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18027 * xfont.c (xfont_match): Avoid need for strlen.
18029 * xfns.c: Don't assume strlen fits in int.

18032 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18033 not unsigned long, as we prefer signed integers. All callers changed.
18034 Detect integer overflow in repeat count.
18035 (message_dolog): Don't assume print length fits in 39 bytes.
18036 (display_mode_element): Don't assume strlen fits in int.
18038 * termcap.c: Don't assume sizes fit in int and never overflow.
18039 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.

18042 * minibuf.c (Fread_buffer):
18043 * lread.c (intern, intern_c_string):

18052 Use ptrdiff_t, not int.
18053 (font_intern_prop): Don't assume string length fits in int.
18054 Don't assume integer property fits in fixnum.
18055 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18057 * filelock.c: Fix some buffer overrun and integer overflow issues.
18058 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18059 Reformulate so as not to need the command string.
18060 Invoke gzip -cd rather than gunzip, as it's more portable.
18061 (lock_info_type, lock_file_1, lock_file):
18062 Don't assume pid_t and time_t fit in unsigned long.
18063 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18064 (current_lock_owner): Prefer signed type for sizes.
18065 Use memcpy, not strncpy, where memcpy is what is really wanted.
18066 Don't assume (via atoi) that time_t and pid_t fit in int.
18067 Check for time_t and/or pid_t out of range, e.g., via a network share.
18068 Don't alloca where an auto var works fine.
18070 * fileio.c: Fix some integer overflow issues.
18071 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18072 Don't assume string length fits in int.
18073 (directory_file_name): Don't assume string length fits in long.
18074 (make_temp_name): Don't assume pid fits in int, or that its print
18075 length is less than 20.
18077 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18079 * coding.c (make_subsidiaries): Don't assume string length fits in int.

18095 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18097 * lread.c (invalid_syntax): Omit length argument.
18098 All uses changed. This doesn't fix a bug, but it simplifies the
18099 code away from its former Hollerith-constant appearance, and it's
18100 one less 'int' to worry about when looking at integer-overflow issues.
18101 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18103 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18104 This didn't break anything, but it didn't help either.
18105 It's confusing to put a bogus integer in a place where the actual
18106 value does not matter.
18107 (LIST_END_P): Remove unused macro and its bogus comment.
18108 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18110 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18111 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18113 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18114 We prefer signed types, and the value cannot exceed the EMACS_INT
18115 range anyway (because otherwise the length would not be representable).
18116 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18117 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18118 This avoids a GCC warning when WIDE_EMACS_INT.
18120 * indent.c (sane_tab_width): New function.
18121 (current_column, scan_for_column, Findent_to, position_indentation)
18122 (compute_motion): Use it. This is just for clarity.
18123 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18125 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

18129 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18131 * editfns.c, insdel.c:
18132 Omit unnecessary forward decls, to simplify future changes.
18134 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18136 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18138 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18139 Use much-faster test for byte-length change.
18140 Don't assume string byte-length fits in 'int'.
18141 Check that character arg fits in 'int'.
18142 (mapcar1): Declare byte as byte, for clarity.
18144 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18146 * fns.c (concat): Catch string overflow earlier.
18147 Do not rely on integer wraparound.
18149 * dispextern.h (struct it.overlay_strings_charpos)
18150 (struct it.selective): Now EMACS_INT, not int.
18151 * xdisp.c (forward_to_next_line_start)
18152 (back_to_previous_visible_line_start)
18153 (reseat_at_next_visible_line_start, next_element_from_buffer):
18154 Don't arbitrarily truncate the value of 'selective' to int.
18156 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18158 * composite.c: Don't truncate sizes to 'int'.
18159 (composition_gstring_p, composition_reseat_it)
18160 (composition_adjust_point): Use EMACS_INT, not int.
18161 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18162 not EMACS_UINT, for indexes.
18164 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18166 * buffer.c: Include <verify.h>.
18167 (struct sortvec.priority, struct sortstr.priority):
18168 Now EMACS_INT, not int.
18169 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18170 (struct sortstr.size, record_overlay_string)
18171 (struct sortstrlist.size, struct sortlist.used):
18172 Don't truncate size to int.
18173 (record_overlay_string): Check for size-calculation overflow.
18174 (init_buffer_once): Check at compile-time, not run-time.
18176 2011-06-22 Jim Meyering <meyering@redhat.com>
18178 Don't leak an XBM-image-sized buffer
18179 * image.c (xbm_load): Free the image buffer after using it.
18181 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18184 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18185 that Sun C diagnosed.
18186 * fns.c (secure_hash): Fix pointer signedness issue.
18187 * intervals.c (static_offset_intervals): New function.
18188 (offset_intervals): Use it.
18190 2011-06-21 Leo Liu <sdl.web@gmail.com>
18193 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18196 * fns.c (secure_hash): Rename from crypto_hash_function and change
18197 the first arg to accept symbols.
18198 (Fsecure_hash): New primitive.
18199 (syms_of_fns): New symbols.
18201 2011-06-20 Deniz Dogan <deniz@dogan.se>
18203 * process.c (Fset_process_buffer): Clarify return value in
18206 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18208 * dispnew.c (add_window_display_history): Use BVAR.

18214 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18217 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18218 check till after the cache is created in init_frame_faces.
18220 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18222 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18224 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18226 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18227 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18228 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18230 Improve buffer-overflow checking (Bug#8873).
18231 * fileio.c (Finsert_file_contents):
18232 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18233 Remove the old (too-loose) buffer overflow checks.
18234 They weren't needed, since make_gap checks for buffer overflow.
18235 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18236 The old code merely checked for Emacs fixnum overflow, and relied
18237 on undefined (wraparound) behavior. The new code avoids undefined
18238 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18240 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18241 Tune. Don't use wider integers than needed. Don't use alloca.
18242 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18244 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18246 * insdel.c, lisp.h (buffer_overflow): New function.
18247 (insert_from_buffer_1, replace_range, replace_range_2):
18248 * insdel.c (make_gap_larger):
18249 * editfns.c (Finsert_char):
18250 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18252 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18254 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18256 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18258 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18259 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18261 * fileio.c: Don't assume EMACS_INT fits in off_t.
18262 (emacs_lseek): New static function.
18263 (Finsert_file_contents, Fwrite_region): Use it.
18264 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18266 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18268 * fns.c: Don't overflow int when computing a list length.
18269 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18270 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18271 truncation on 64-bit hosts. Check for QUIT every
18272 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18273 faster and is responsive enough.
18274 (Flength): Report an error instead of overflowing an integer.
18275 (Fsafe_length): Return a float if the value is not representable
18276 as a fixnum. This shouldn't happen except in contrived situations.
18277 (Fnthcdr, Fsort): Don't assume list length fits in int.
18278 (Fcopy_sequence): Don't assume vector length fits in int.
18280 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18281 (header_size, word_size): New constants.
18282 (allocate_vectorlike): Don't check size overflow here.
18283 (allocate_vector): Check it here instead, since this is the only
18284 caller of allocate_vectorlike that could cause overflow.
18285 Check that the new vector's length is representable as a fixnum.
18287 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18288 The previous code was bogus. For example, next_almost_prime (32)
18289 returned 39, which is undesirable as it is a multiple of 3; and
18290 next_almost_prime (24) returned 25, which is a multiple of 5 so
18291 why was the code bothering to check for multiples of 7?
18293 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18295 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18297 Variadic C functions now count arguments with ptrdiff_t.
18298 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18299 Back then I didn't know that the Emacs coding style prefers signed int.
18300 Also, in the meantime I found a few more instances where arguments
18301 were being counted with int, which may truncate counts on 64-bit
18302 machines, or EMACS_INT, which may be unnecessarily wide.
18303 * lisp.h (struct Lisp_Subr.function.aMANY)
18304 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18305 Arg counts are now ptrdiff_t, not size_t.
18306 All variadic functions and their callers changed accordingly.
18307 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18308 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18309 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18310 * callint.c (Fcall_interactively): Check arg count for overflow,
18311 to avoid potential buffer overrun. Use signed char, not 'int',
18312 for 'varies' array, so that we needn't bother to check its size
18313 calculation for overflow.
18314 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18315 * eval.c (apply_lambda):
18316 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18317 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18318 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18320 * callint.c (Fcall_interactively): Don't use index var as event count.
18322 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18323 * mem-limits.h (SIZE): Remove; no longer used.
18325 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18327 Remove unnecessary casts.
18328 * xterm.c (x_term_init):
18329 * xfns.c (x_set_border_pixel):
18330 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18331 These aren't needed now that we assume ANSI C.
18333 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18334 It's more likely to cause problems (due to unsigned overflow)
18337 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18339 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18341 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18343 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18345 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18347 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18349 GLYPH_CODE_FACE returns EMACS_INT, not int.
18350 * dispextern.h (merge_faces):
18351 * xfaces.c (merge_faces):
18352 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18353 Don't assume EMACS_INT fits in int.
18355 * character.h (CHAR_VALID_P): Remove unused parameter.
18356 * fontset.c, lisp.h, xdisp.c: All uses changed.
18358 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18360 * fns.c (concat): Minor tuning based on overflow analysis.
18361 This doesn't fix any bugs. Use int to hold character, instead
18362 of constantly refetching from Emacs object. Use XFASTINT, not
18363 XINT, for value known to be a character. Don't bother comparing
18364 a single byte to 0400, as it's always less.
18366 * floatfns.c (Fexpt):
18367 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18369 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18372 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18374 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18375 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18376 incorrectly succeed when S was a string, because 4294967386 was
18377 truncated before it was used.
18379 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18380 Otherwise, an out-of-range integer could cause undefined behavior
18383 * composite.c: Use int, not EMACS_INT, for characters.
18384 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18385 EMACS_INT, for values that are known to be in character range.
18386 This doesn't fix any bugs but is the usual style inside Emacs and
18387 may generate better code on 32-bit machines.
18389 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18390 This is for reasons similar to the recent CHAR_STRING fix.
18391 * charset.c (Fencode_char): Check that character arg is actually
18392 a character. Pass an int to ENCODE_CHAR.
18393 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18394 wider than 'int', as a compile-time check to prevent future regressions
18397 * character.c (char_string): Remove unnecessary casts.
18399 Make sure a 64-bit char is never passed to CHAR_STRING.
18400 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18401 by silently ignoring the top 32 bits, allowing some values
18402 that were far too large to be valid characters.
18403 * character.h: Include <verify.h>.
18404 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18405 arguments are no wider than unsigned, as a compile-time check
18406 to prevent future regressions in this area.
18408 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18409 (Fsubst_char_in_region):
18411 * xdisp.c (decode_mode_spec_coding):
18412 Adjust to CHAR_STRING's new requirement.
18413 * editfns.c (Finsert_char, Fsubst_char_in_region):
18414 * fns.c (concat): Check that character args are actually
18415 characters. Without this test, these functions did the wrong
18416 thing with wildly out-of-range values on 64-bit hosts.
18418 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18419 These casts should not be needed on 32-bit hosts, either.
18420 * keyboard.c (read_char):
18421 * lread.c (Fload): Remove casts to unsigned.
18423 * lisp.h (UNSIGNED_CMP): New macro.
18424 This fixes comparison bugs on 64-bit hosts.
18425 (ASCII_CHAR_P): Use it.
18426 * casefiddle.c (casify_object):
18427 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18428 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18429 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18430 * dispextern.h (FACE_FROM_ID):
18431 * keyboard.c (read_char): Use UNSIGNED_CMP.
18433 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18434 not to EMACS_INT, to avoid GCC warning.
18436 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18438 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18439 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18440 isn't needed on 32-bit machines.
18442 * buffer.c (Fgenerate_new_buffer_name):
18443 Use EMACS_INT for count, not int.
18444 (advance_to_char_boundary): Return EMACS_INT, not int.
18446 * data.c (Qcompiled_function): Now static.
18448 * window.c (window_body_lines): Now static.
18450 * image.c (gif_load): Rename local to avoid shadowing.
18452 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18453 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18454 * alloc.c (make_save_value): Integer argument is now of type
18455 ptrdiff_t, not int.
18456 (mark_object): Use ptrdiff_t, not int.
18457 * lisp.h (pD): New macro.
18458 * print.c (print_object): Use it.
18460 * alloc.c: Use EMACS_INT, not int, to count objects.
18461 (total_conses, total_markers, total_symbols, total_vector_size)
18462 (total_free_conses, total_free_markers, total_free_symbols)
18463 (total_free_floats, total_floats, total_free_intervals)
18464 (total_intervals, total_strings, total_free_strings):
18465 Now EMACS_INT, not int. All uses changed.
18466 (Fgarbage_collect): Compute overall total using a double, so that
18467 integer overflow is less likely to be a problem. Check for overflow
18468 when converting back to an integer.
18469 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18470 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18471 These were 'int' variables that could overflow on 64-bit hosts;
18472 they were never used, so remove them instead of repairing them.
18473 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18474 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18475 Previously, this ceilinged at INT_MAX, but that doesn't work on
18477 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18479 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18480 (allocate_vectorlike): Check for ptrdiff_t overflow.
18481 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18482 when a (possibly-narrower) signed value would do just as well.
18483 We prefer using signed arithmetic, to avoid comparison confusion.
18485 * alloc.c: Catch some string size overflows that we were missing.
18486 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18487 for convenience in STRING_BYTES_MAX.
18488 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18489 The definition here is exact; the one in lisp.h was approximate.
18490 (allocate_string_data): Check for string overflow. This catches
18491 some instances we weren't catching before. Also, it catches
18492 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18493 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18494 and ptrdiff_t and EMACS_INT are both 64 bits.
18496 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18497 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18498 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18500 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18502 * alloc.c (Fmake_string): Check for out-of-range init.
18504 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18506 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18508 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18510 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18511 xg_get_default_scrollbar_width.
18513 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18514 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18515 (style_changed_cb): Call update_theme_scrollbar_width and call
18516 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18517 all frames (Bug#8505).
18518 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18519 Call gtk_window_set_resizable if HAVE_GTK3.
18520 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18521 and height if HAVE_GTK3 (Bug#8505).
18522 (scroll_bar_width_for_theme): New variable.
18523 (update_theme_scrollbar_width): New function.
18524 (xg_get_default_scrollbar_width): Move code to
18525 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18526 (xg_initialize): Call update_theme_scrollbar_width.
18528 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18530 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18532 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18534 * frame.c (make_frame): Call other_buffer_safely instead of
18537 * window.c (temp_output_buffer_show): Call display_buffer with
18538 second argument Vtemp_buffer_show_specifiers and reset latter
18539 immediately after the call.
18540 (Vtemp_buffer_show_specifiers): New variable.
18541 (auto_window_vscroll_p, next_screen_context_lines)
18542 (Vscroll_preserve_screen_position): Remove leading asterisks from
18545 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18547 Fix minor problems found by GCC 4.6.0 static checking.
18548 * buffer.c (Qclone_number): Remove for now, as it's unused.
18549 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18550 (record_buffer): Remove unused local.
18551 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18552 (set_frame_buffer_list): Remove; unused.
18553 * frame.h (other_visible_frames): Remove decl.
18554 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18555 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18556 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18558 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18559 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18560 Define only if HAVE_GPM.
18561 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18562 (update_hints_inhibit): Remove; never set. All uses removed.
18563 * widgetprv.h (emacsFrameClassRec): Remove decl.
18564 * window.c (delete_deletable_window): Now returns void, since it
18565 wasn't returning anything.
18566 (compare_window_configurations): Remove unused locals.
18567 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18568 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18569 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18570 the same widths as pointers. This follows up on the 2011-05-06 patch.
18571 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18572 * xterm.h: Likewise.
18573 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18575 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18577 * makefile.w32-in: Update dependencies.
18578 (LISP_H): Add lib/intprops.h.
18580 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18582 * image.c (gif_load): Add animation frame delay to the metadata.
18583 (syms_of_image): Use DEFSYM. New symbol `delay'.
18585 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18587 * window.c (delete_deletable_window): Re-add.
18588 (Fset_window_configuration): Rewrite to handle dead buffers and
18589 consequently deletable windows.
18590 (window_tree, Fwindow_tree): Remove. Supply functionality in
18592 (compare_window_configurations): Simplify code.
18594 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18596 * image.c (imagemagick_load_image): Fix type mismatch.
18597 (Fimagemagick_types): Likewise.
18599 * window.h (replace_buffer_in_windows): Declare.
18601 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18603 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18604 Qclone_number. Remove external declaration of Qdelete_window.
18605 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18607 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18608 Run Qbuffer_list_update_hook if allowed.
18609 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18610 buffer list implementation.
18611 (other_buffer_safely): New function.
18612 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18613 calls to replace_buffer_in_windows and
18614 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18616 (record_buffer): Inhibit quitting and rewrite using quittable
18617 functions. Run Qbuffer_list_update_hook if allowed.
18618 (Frecord_buffer, Funrecord_buffer): New functions.
18619 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18620 Move switch-to-buffer to window.el.
18621 (bury-buffer): Move to window.el.
18622 (Vbuffer_list_update_hook): New variable.
18624 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18627 * window.h (resize_frame_windows): Move up in code.
18628 (Fwindow_frame): Remove EXFUN.
18629 (replace_buffer_in_all_windows): Remove prototype.
18630 (replace_buffer_in_windows_safely): Add prototype.
18632 * window.c: Declare Qdelete_window static again. Move down
18633 declaration of select_count.
18634 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18635 (Fother_window): Move to window.el.
18636 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18637 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18638 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18640 (replace_buffer_in_windows): Implement by calling
18641 Qreplace_buffer_in_windows.
18642 (replace_buffer_in_all_windows): Remove with some functionality
18643 moved into replace_buffer_in_windows_safely.
18644 (replace_buffer_in_windows_safely): New function.
18645 (select_window_norecord, select_frame_norecord): Move in front
18646 of run_window_configuration_change_hook. Remove now obsolete
18648 (Fset_window_buffer): Rewrite doc-string.
18649 Call Qrecord_window_buffer.
18650 (keys_of_window): Move binding for other-window to window.el.
18652 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18654 * dispextern.h (struct image): Replace data member, whose int_val
18655 and ptr_val fields were not used by anything, with a single
18658 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18659 (gif_clear_image, gif_load, imagemagick_load_image)

19103 last portion of handle_display_prop.
19104 (compute_display_string_pos): Accept additional argument
19105 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19106 value of a `display' property is a "replacing spec".
19107 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19108 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19109 the display property, but just return a value indicating whether
19110 the display property will replace the characters it covers.
19111 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19112 frame_window_p members of struct bidi_it.
19113 (compute_display_string_pos, compute_display_string_end):
19115 (push_it): Accept second argument POSITION, where pop_it should
19116 jump to continue iteration.
19117 (reseat_1): Initialize bidi_it.disp_pos.
19119 * keyboard.c (adjust_point_for_property): Adjust the call to
19120 display_prop_intangible_p to its new signature.
19122 * dispextern.h (struct bidi_it): New member frame_window_p.
19123 (bidi_init_it): Update prototypes.

19125 (compute_display_string_pos, compute_display_string_end):
19126 Declare prototypes.
19127 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19130 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19132 Malloc failure behavior now depends on size of allocation.
19133 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19134 * lisp.h: Change signatures accordingly.
19135 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19136 All callers changed. (Bug#8762)
19138 * gnutls.c: Use Emacs's memory allocators.
19139 Without this change, the gnutls library would invoke malloc etc.
19140 directly, which causes problems on non-SYNC_INPUT hosts, and which
19141 runs afoul of improving memory_full behavior. (Bug#8761)
19142 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19143 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19144 xfree instead of the default malloc, realloc, free.
19145 (Fgnutls_boot): No need to check for memory allocation failure,
19146 since xmalloc does that for us.
19148 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19149 * category.c (hash_get_category_set):
19150 * ccl.c (ccl_driver):
19151 * charset.c (Fdefine_charset_internal):
19152 * charset.h (struct charset.hash_index):
19153 * composite.c (get_composition_id, gstring_lookup_cache)
19154 (composition_gstring_put_cache):
19155 * composite.h (struct composition.hash_index):
19156 * dispextern.h (struct image.hash):
19157 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19158 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
19159 (hashfn_equal, hashfn_user_defined, make_hash_table)

19161 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19162 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19163 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19164 * image.c (make_image, search_image_cache, lookup_image)
19165 (xpm_put_color_table_h):
19166 * lisp.h (struct Lisp_Hash_Table):
19167 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19168 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19169 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19170 * alloc.c (allocate_vectorlike):
19171 Check for overflow in vector size calculations.
19172 * ccl.c (ccl_driver):
19173 Check for overflow when converting EMACS_INT to int.
19174 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19175 need to be updated by these changes.
19176 * fns.c (make_hash_table, maybe_resize_hash_table):
19177 Check for integer overflow with large hash tables.
19178 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19179 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19180 (SXHASH_REDUCE): New macro.
19181 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19182 Use it instead of discarding useful hash info with large hash values.
19183 (sxhash_float): New function.
19184 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19185 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19186 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19187 Rewrite to use FIXNUM_BITS, as this simplifies things.
19188 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19189 Adjust signatures to match updated version of code.
19190 (consing_since_gc): Now EMACS_INT, since a single hash table can
19191 use more than INT_MAX bytes.
19193 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19195 Make it possible to build with GCC-4.6+ -O2 -flto.
19197 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19199 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19201 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19202 Call minibuffer-inactive-mode.
19204 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19206 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19207 Update dependencies.
19209 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19211 * data.c (init_data): Remove code for UTS, this system is not
19214 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19216 Don't force ./temacs to start in terminal mode.
19218 * frame.c (make_initial_frame): Initialize faces in all cases, not
19219 only when CANNOT_DUMP is defined.
19220 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19222 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19224 * dispnew.c (add_window_display_history): Use const for the string
19225 pointer. Remove declaration, not needed.
19227 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19229 Use 'inline', not 'INLINE'.
19230 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19231 * alloc.c, fontset.c (INLINE): Remove.
19232 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19233 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19234 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19235 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19236 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19238 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19240 Make it possible to run ./temacs.
19242 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19243 syms_of_callproc does the same thing. Remove test for
19244 "initialized", do it in the caller.
19245 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19247 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19249 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19250 (read_minibuf): Use get_minibuffer.
19251 (syms_of_minibuf): Use DEFSYM.
19252 (Qmetadata): New var.
19253 * data.c (Qbuffer): Don't make it static.
19254 (syms_of_data): Use DEFSYM.
19256 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19258 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19259 (CCL_CODE_MIN): New macro.
19261 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19263 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19265 * eval.c (Qdebug): Now static.
19266 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19267 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19268 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19270 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19272 * image.c: Various fixes to ImageMagick code comments.
19273 (Fimagemagick_types): Doc fix.
19275 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19277 Minor fixes prompted by GCC 4.6.0 warnings.
19279 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19281 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19282 (x_clipboard_manager_save_all): Move extern decl to ...
19283 * xterm.h: ... here, so that it can be checked for consistency.
19285 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19287 * xselect.c (x_clipboard_manager_save_frame)
19288 (x_clipboard_manager_save_all): New functions.
19289 (Fx_clipboard_manager_save): Lisp function deleted.
19291 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19292 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19294 * xterm.h: Update prototype.
19296 2011-05-28 William Xu <william.xwl@gmail.com>
19298 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19299 exiting (Bug#8239).
19301 2011-05-28 Jim Meyering <meyering@redhat.com>
19303 Avoid a sign-extension bug in crypto_hash_function.
19304 * fns.c (to_uchar): Define.
19305 (crypto_hash_function): Use it to convert some newly-signed
19306 variables to unsigned, to avoid sign-extension bugs. For example,
19307 without this change, (md5 "truc") would evaluate to
19308 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19309 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19310 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19312 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19314 Integer overflow fixes.
19316 * dbusbind.c: Serial number integer overflow fixes.
19317 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19318 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19319 to hold a serial number that is too large for a fixnum.
19320 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19321 Check for serial numbers out of range. Decode any serial number
19322 that was so large that it became a float. (Bug#8722)
19324 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19325 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19326 Use XFASTINT rather than XUINT when numbers are nonnegative.
19327 (xd_append_arg, Fdbus_method_return_internal):
19328 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19329 arguments, check that Lisp number is nonnegative, rather than
19330 silently wrapping negative numbers around. (Bug#8722)
19331 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19334 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19336 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19338 ccl: Add integer overflow checks.
19339 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19340 (IN_INT_RANGE): New macros.
19341 (ccl_driver): Use them to check for integer overflow when
19342 decoding a CCL program. Many of the new checks are whether XINT (x)
19343 fits in int; it doesn't always, on 64-bit hosts. The new version
19344 doesn't catch all possible integer overflows, but it's an
19345 improvement. (Bug#8719)
19347 * alloc.c (make_event_array): Use XINT, not XUINT.
19348 There's no need for unsigned here.
19350 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19351 This follows up to the 2011-05-06 change that substituted uintptr_t
19352 for EMACS_INT. This case wasn't caught back then.
19354 Rework Fformat to avoid integer overflow issues.
19355 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19356 now (part of C89). Include <verify.h>.
19357 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19358 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19359 (Fformat): Avoid the prepass trying to compute sizes; it was only
19360 approximate and thus did not catch overflow reliably. Instead, walk
19361 through the format just once, formatting and computing sizes as we go,
19362 checking for integer overflow at every step, and allocating a larger
19363 buffer as needed. Keep track separately whether the format is
19364 multibyte. Keep only the most-recently calculated precision, rather
19365 than them all. Record whether each argument has been converted to
19366 string. Use EMACS_INT, not int, for byte and char and arg counts.
19367 Support field widths and precisions larger than INT_MAX. Avoid
19368 sprintf's undefined behavior with conversion specifications such as %#d
19369 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19370 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19371 formatting out-of-range floating point numbers with int
19372 formats. (Bug#8668)
19374 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19376 * data.c: Avoid integer truncation in expressions involving floats.
19377 * data.c: Include <intprops.h>.
19378 (arith_driver): When there's an integer overflow in an expression
19379 involving floating point, convert the integers to floating point
19380 so that the resulting value does not suffer from catastrophic
19381 integer truncation. For example, on a 64-bit host (* 4
19382 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19383 Do not rely on undefined behavior after integer overflow.
19385 merge count_size_as_multibyte, parse_str_to_multibyte
19386 * character.c, character.h (count_size_as_multibyte):
19387 Rename from parse_str_to_multibyte; all uses changed.
19388 Check for integer overflow.
19389 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19390 since it's now a duplicate of the other. This is more of
19391 a character than a buffer op, so better that it's in character.c.
19392 * fns.c, print.c: Adjust to above changes.
19394 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19396 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19398 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19400 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19401 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19402 (x_clipboard_manager_save): Now static.
19403 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19405 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19406 (crypto_hash_function): Now static.
19407 Fix pointer signedness problems. Avoid unnecessary initializations.
19409 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19411 * termhooks.h (Vselection_alist): Make it terminal-local.
19413 * terminal.c (create_terminal): Initialize it.
19415 * xselect.c: Support for clipboard managers.
19416 (Vselection_alist): Move to termhooks.h as terminal-local var.
19417 (LOCAL_SELECTION): New macro.
19418 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19419 (symbol_to_x_atom): Remove gratuitous arg.
19420 (x_handle_selection_request, lisp_data_to_selection_data)
19421 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19422 (x_own_selection, x_get_local_selection, x_convert_selection):
19423 New arg, specifying work frame. Use terminal-local Vselection_alist.
19424 (some_frame_on_display): Delete unused function.
19425 (Fx_own_selection_internal, Fx_get_selection_internal)
19426 (Fx_disown_selection_internal, Fx_selection_owner_p)
19427 (Fx_selection_exists_p): New optional frame arg.
19428 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19429 (x_handle_selection_clear): Don't treat other terminals with the
19430 same keyboard specially. Use the terminal-local Vselection_alist.
19431 (x_clear_frame_selections): Use Frun_hook_with_args.
19433 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19435 * xterm.h: Add support for those atoms.
19437 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19439 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19440 (converted_selections, conversion_fail_tag): New global variables.
19441 (x_selection_request_lisp_error): Free the above.
19442 (x_get_local_selection): Remove unnecessary code.
19443 (x_reply_selection_request): Args changed; handle arbitrary array
19444 of converted selections stored in converted_selections.
19445 Separate the XChangeProperty and SelectionNotify steps.
19446 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19447 (x_convert_selection): New function.
19448 (x_handle_selection_event): Simplify.
19449 (x_get_foreign_selection): Don't ignore incoming requests while
19450 waiting for an answer; this will fail when we implement
19451 SAVE_TARGETS, and seems unnecessary anyway.
19452 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19453 (Vx_sent_selection_functions): Doc fix.
19455 2011-05-26 Leo Liu <sdl.web@gmail.com>
19457 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19459 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19461 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19463 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19464 for fringe update if it has periodic bitmap.
19465 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19466 and fringe_bitmap_periodic_p.
19468 * fringe.c (get_fringe_bitmap_data): New function.
19469 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19470 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19471 row. Mark glyph row for fringe update if periodicity changed.
19473 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19474 for fringe update unless it has periodic bitmap.
19476 2011-05-25 Kenichi Handa <handa@m17n.org>
19478 * xdisp.c (get_next_display_element): Set correct it->face_id for
19479 a static composition.

19492 * gnutls.c: Remove unused macros.
19493 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19494 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19495 Remove macros that are defined and never used.
19496 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19498 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19500 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19501 (Fx_get_selection_internal): Minor cleanup.
19502 (Fx_own_selection_internal): Rename arguments for consistency with
19505 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

19527 report_file_error introduced by the change from 2011-05-07.
19529 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19531 * systime.h (Time): Define only if emacs is defined.
19532 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19533 where the include path doesn't have X11/X.h by default. See
19534 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19536 2011-05-20 Kenichi Handa <handa@m17n.org>
19538 * composite.c (find_automatic_composition): Fix previous change.
19540 2011-05-20 Glenn Morris <rgm@gnu.org>
19542 * lisp.mk: New file, split from Makefile.in.
19543 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19544 (shortlisp): Remove.
19545 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19547 2011-05-19 Glenn Morris <rgm@gnu.org>
19549 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19550 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19551 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19552 (lisp): Set the order to that of loadup.el.
19553 (shortlisp): Make it a copy of $lisp.
19554 (SOME_MACHINE_LISP): Remove.
19555 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19556 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19558 2011-05-18 Kenichi Handa <handa@m17n.org>
19560 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19561 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19562 (find_automatic_composition): Mostly rewrite for efficiency.
19564 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19566 * makefile.w32-in: Update dependencies.
19568 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19570 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19571 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19573 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19575 Fix some integer overflow issues, such as string length overflow.
19577 * insdel.c (count_size_as_multibyte): Check for string overflow.
19579 * character.c (lisp_string_width): Check for string overflow.
19580 Use EMACS_INT, not int, for string indexes and lengths; in
19581 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19582 the resulting string length overflows an EMACS_INT; instead,
19583 report a string overflow if no precision given. When checking for
19584 precision exhaustion, use a check that cannot possibly have
19585 integer overflow. (Bug#8675)
19586 * character.h (lisp_string_width): Adjust to new signature.
19588 * alloc.c (string_overflow): New function.
19589 (Fmake_string): Use it. This doesn't change behavior, but saves
19590 a few bytes and will simplify future changes.
19591 * character.c (string_escape_byte8): Likewise.
19592 * lisp.h (string_overflow): New decl.
19594 Fixups, following up to the user-interface timestamp change.
19595 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19596 for UI timestamps, instead of unsigned long.
19597 * msdos.c (mouse_get_pos): Likewise.
19598 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19599 * w32gui.h (Time): Define by including "systime.h" rather than by
19600 declaring it ourselves. (Bug#8664)
19602 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19603 * image.c (clear_image_cache): Likewise.
19605 * term.c (term_mouse_position): Don't assume time_t wraparound.
19607 Be more systematic about user-interface timestamps.
19608 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19609 and sometimes 'EMACS_UINT', to represent these timestamps.
19610 This change causes it to use 'Time' uniformly, as that's what X uses.
19611 This makes the code easier to follow, and makes it easier to catch
19612 integer overflow bugs such as Bug#8664.
19613 * frame.c (Fmouse_position, Fmouse_pixel_position):
19614 Use Time, not unsigned long, for user-interface timestamps.
19615 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19616 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19617 * keyboard.h (last_event_timestamp): Likewise.
19618 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19619 * menu.h (xmenu_show): Likewise.
19620 * term.c (term_mouse_position): Likewise.
19621 * termhooks.h (struct input_event.timestamp): Likewise.
19622 (struct terminal.mouse_position_hook): Likewise.
19623 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19624 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19625 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19626 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19627 what it was before.
19628 * menu.h, termhooks.h: Include "systime.h", for Time.
19630 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19631 Don't assume that the difference between two unsigned long values
19632 can fit into an integer. At this point, we know button_down_time
19633 <= event->timestamp, so the difference must be nonnegative, so
19634 there's no need to cast the result if double-click-time is
19635 nonnegative, as it should be; check that it's nonnegative, just in
19636 case. This bug is triggered when events are more than 2**31 ms
19637 apart (about 25 days). (Bug#8664)
19639 * xselect.c (last_event_timestamp): Remove duplicate decl.
19640 (x_own_selection): Remove needless cast to unsigned long.
19642 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19643 that always fit in int. Use a sentinel instead of a counter, to
19644 avoid a temp and to allay GCC's concerns about possible int overflow.
19645 * frame.h (struct frame): Use int for menu_bar_items_used
19646 instead of EMACS_INT, since it always fits in int.
19648 * menu.c (grow_menu_items): Check for int overflow.
19650 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19652 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19653 Before, the code was not consistent. These values cannot exceed
19654 2**31 - 1 so there's no need to make them unsigned.
19655 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19656 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19657 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19659 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19661 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19662 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19663 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19664 presumably because the widths might not match.
19666 * window.c (size_window): Avoid needless test at loop start.
19668 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19670 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19672 2011-05-12 Drew Adams <drew.adams@oracle.com>
19674 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19676 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19678 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19679 `width' to `bar_area_x' and `bar_area_width', respectively.
19680 (x_scroll_run): Take account of fringe background extension.
19682 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19683 Rename local vars `left' and `width' to `bar_area_x' and
19684 `bar_area_width', respectively.
19685 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19686 background extension.
19688 2011-05-10 Jim Meyering <meyering@redhat.com>
19690 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19692 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19694 * image.c (Finit_image_library): Return t for built-in image types,
19695 like pbm and xbm. (Bug#8640)
19697 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19699 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19701 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19703 * w32console.c (Fset_screen_color): Doc fix.
19704 (Fget_screen_color): New function.
19705 (syms_of_ntterm): Defsubr it.
19707 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19708 unlink the temporary file if Fcall_process didn't create it in the
19710 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19711 child process will be redirected to a file specified with `:file'.
19712 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19713 cue to call_process_cleanup not to close that handle.
19715 2011-05-07 Ben Key <bkey76@gmail.com>
19717 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19718 one of two shell specific rules, either bootstrap-temacs-CMD or
19719 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19720 to the previous implementation of the bootstrap-temacs rule.
19721 The bootstrap-temacs-CMD rule is similar to the previous
19722 implementation of the bootstrap-temacs rule except that it
19723 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19726 These changes, along with some changes to nt/configure.bat,
19727 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19728 earlier fix to add support for --cflags and --ldflags options
19729 that include quotes so that it works whether make uses cmd or
19732 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19734 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19735 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19737 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19738 a string. Handle both cases.
19739 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19740 (Fdbus_register_method): Use Qinvalid_function.
19742 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19744 * makefile.w32-in: Update dependencies.
19745 (LISP_H): Add inttypes.h and stdin.h.
19746 (PROCESS_H): Add unistd.h.
19748 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19750 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19751 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19753 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19755 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19757 * term.c (vfatal): Remove stray call to va_end.
19758 It's not needed and the C Standard doesn't allow it here anyway.
19760 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19761 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19763 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19766 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19768 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19770 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19772 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19774 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19776 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19777 * charset.c (Fdefine_charset_internal): Don't initialize
19778 charset.code_space[15]. The value was garbage, on hosts with
19779 32-bit int (Bug#8600).
19781 * lread.c (read_integer): Be more consistent with string-to-number.
19782 Use string_to_number to do the actual conversion; this avoids
19783 rounding errors and fixes some other screwups. Without this fix,
19784 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19785 (digit_to_number): Move earlier, for benefit of read_integer.
19786 Return -1 if the digit is out of range for the base, -2 if it is
19787 not a digit in any supported base. (Bug#8602)
19789 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19791 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19792 to match comment at start of function. This also removes a
19793 GCC warning about overflow in a 32+64-bit port.
19795 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19797 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19798 Reported by Stefan Monnier in
19799 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19800 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19801 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19803 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19804 (EMACS_UINTPTR): Likewise, with uintptr_t.
19806 * lisp.h: Prefer 64-bit EMACS_INT if available.
19807 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19808 on 32-bit hosts that have 64-bit int, so that they can access
19810 However, temporarily disable this change unless the temporary
19811 symbol WIDE_EMACS_INT is defined.
19813 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19815 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19816 This removes an assumption that EMACS_INT and long are the same
19817 width as pointers. The assumption is true for Emacs porting targets
19818 now, but we want to make other targets possible.
19819 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19820 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19821 In the rest of the code, change types of integers that hold casted
19822 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19823 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19824 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19825 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19826 No need to cast type when ORing.
19827 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19828 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19829 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19830 assume EMACS_INT is the same width as char *.
19831 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19832 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19833 Remove no-longer-needed casts.
19834 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19835 (xg_tool_bar_help_callback, xg_make_tool_item):
19836 Use EMACS_INTPTR to hold an integer
19837 that will be cast to void *; this can avoid a GCC warning
19838 if EMACS_INT is not the same width as void *.
19839 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19840 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19841 (current_message_1, set_message_1):
19842 Use a local to convert to proper width without a cast.
19843 * xmenu.c (dialog_selection_callback): Likewise.
19845 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19846 Also, don't assume VALBITS / RAND_BITS is less than 5,
19847 and don't rely on undefined behavior when shifting a 1 left into
19849 * lisp.h (get_random): Change signature to match.
19851 * lread.c (hash_string): Use size_t, not int, for hash computation.
19852 Normally we prefer signed values; but hashing is special, because
19853 it's better to use unsigned division on hash table sizes so that
19854 the remainder is nonnegative. Also, size_t is the natural width
19855 for hashing into memory. The previous code used 'int', which doesn't
19856 retain enough info to hash well into very large tables.
19857 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19859 * dbusbind.c: Don't possibly lose pointer info when converting.
19860 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19861 Use XPNTR rather than XHASH, so that the high-order bits of
19862 the pointer aren't lost when converting through void *.
19864 * eval.c (Fautoload): Don't double-shift a pointer.
19866 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19868 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19870 * gnutls.c (DEF_GNUTLS_FN):
19871 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19873 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19875 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19878 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19880 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19881 New version that can reserve upto 2GB of heap space.
19883 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19885 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19887 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19889 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19890 `gnutls_certificate_set_x509_key_file'.
19892 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19894 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19895 Update dependencies.
19897 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19899 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19900 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19901 Remove unused parameter `fildes'.
19902 * process.c (read_process_output, send_process): Don't pass it.
19904 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19906 Fix previous change: the library cache is defined in w32.c.
19907 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19908 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19910 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19912 Implement dynamic loading of GnuTLS on Windows.
19914 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19915 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19916 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19919 * gnutls.c (Qgnutls_dll): Define.
19920 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19921 (gnutls_*): Declare function pointers.
19922 (init_gnutls_functions): New function to initialize function pointers.
19923 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19924 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19925 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19926 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19927 (emacs_gnutls_write, emacs_gnutls_read)
19928 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19929 (Fgnutls_available_p): New function.
19930 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19931 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19932 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19934 * image.c: Include w32.h.
19935 (Vimage_type_cache): Delete.
19936 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19937 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19938 (w32_delayed_load): Move to w32.c.
19940 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19942 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19943 (w32_delayed_load): Move from image.c. When loading a library, record
19944 its filename in the :loaded-from property of the library id.
19945 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19946 Initialize and staticpro them.
19947 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19949 * process.c: Include lisp.h before w32.h, not after.
19950 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19951 instead of gnutls_record_check_pending.
19953 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19955 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19957 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19958 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19961 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19963 * xterm.c (x_set_frame_alpha): Do not set property on anything

20000 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20002 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20003 rather than `XVECTOR (FOO)->size'.
20005 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20006 inttypes.h, as a gnulib replacement is used if it not available in
20009 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20011 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20012 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20013 of MOST_POSITIVE_FIXNUM. (Bug#8528)

20019 space for up to 2 characters produced in a loop.
20020 (decode_coding_iso_2022): Abort if there isn't enough place in
20021 charbuf for the composition carryover bytes.
20023 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20025 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20026 aborting when %lld or %lll format is passed.
20027 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20028 %llo or %llx format is passed. (Bug#8545)
20030 * window.c (window_scroll_line_based): Use a marker instead of
20031 simple variables to record original value of point. (Bug#7952)
20033 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20034 produced by %s or %c overflows available buffer space. (Bug#8545)
20036 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20038 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20039 (SIZE_MAX): Move defn after all includes, as they might #define it.
20041 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20043 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20045 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20047 * keyboard.c (Qdelayed_warnings_hook): Define.
20048 (command_loop_1): Run `delayed-warnings-hook'
20049 if Vdelayed_warnings_list is non-nil.
20050 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20051 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20053 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20055 * doprnt.c (doprnt): Don't return value smaller than the buffer
20056 size if the message was truncated. (Bug#8545).
20058 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20060 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20061 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20063 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20065 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20067 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20069 * makefile.w32-in: Update dependencies.
20071 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20073 Improve `doprnt' and its usage. (Bug#8545)
20074 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20075 `format_end'. Remove support for %l as a conversion specifier.
20076 Don't use xrealloc. Improve diagnostics when the %l size modifier
20077 is used. Update the commentary.
20079 * eval.c (verror): Simplify calculation of size_t.
20081 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20084 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20086 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20089 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20091 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20092 This makes this file independent of the recent pseudovector change.
20094 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20096 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20098 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20099 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20100 Remove unused local.
20101 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20103 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20104 GCC 4.6.0 optimizes based on type-based alias analysis.
20105 For example, if b is of type struct buffer * and v of type struct
20106 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20107 != &v->size, and therefore "v->size = 1; b->size = 2; return
20108 v->size;" must therefore return 1. This assumption is incorrect
20109 for Emacs, since it type-puns struct Lisp_Vector * with many other
20110 types. To fix this problem, this patch adds a new type struct
20111 vectorlike_header that documents the constraints on layout of vectors
20112 and pseudovectors, and helps optimizing compilers not get fooled
20113 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20114 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20115 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20117 (XSETPVECTYPE): Rewrite in terms of new macro.
20118 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20119 This is a bit clearer, and further avoids the possibility of
20120 undesirable aliasing.
20121 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20122 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20123 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20124 since Lisp_Subr is a special case (no "next" field).
20125 (ASIZE): Now uses header.size rather than size.
20126 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20127 to avoid the hassle of writing XVECTOR (foo)->header.size.
20128 (struct vectorlike_header): New type.
20129 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20130 object, to help avoid aliasing.
20131 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20132 (SUBRP): Likewise, since Lisp_Subr is a special case.
20133 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20134 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20135 (struct Lisp_Hash_Table): Combine first two members into a single
20136 struct vectorlike_header member. All uses of "size" and "next" members
20137 changed to be "header.size" and "header.next".
20138 * buffer.h (struct buffer): Likewise.
20139 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20140 * frame.h (struct frame): Likewise.
20141 * process.h (struct Lisp_Process): Likewise.
20142 * termhooks.h (struct terminal): Likewise.
20143 * window.c (struct save_window_data, struct saved_window): Likewise.
20144 * window.h (struct window): Likewise.
20145 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20146 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20147 * buffer.c (init_buffer_once): Likewise.
20148 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20150 * process.c (Fformat_network_address): Use local var for size,
20153 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20155 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20156 * data.c (atof): Remove decl; no longer used or needed.
20157 (digit_to_number): Move to lread.c.
20158 (Fstring_to_number): Use new string_to_number function, to be
20159 consistent with how the Lisp reader treats infinities and NaNs.
20160 Do not assume that floating-point numbers represent EMACS_INT
20161 without losing information; this is not true on most 64-bit hosts.
20162 Avoid double-rounding errors, by insisting on integers when
20163 parsing non-base-10 numbers, as the documentation specifies.
20164 * lisp.h (string_to_number): New decl, replacing ...
20165 (isfloat_string): Remove.
20166 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20167 (read1): Do not accept +. and -. as integers; this
20168 appears to have been a coding error. Similarly, do not accept
20169 strings like +-1e0 as floating point numbers. Do not report
20170 overflow for integer overflows unless the base is not 10 which
20171 means we have no simple and reliable way to continue.
20172 Break out the floating-point parsing into a new
20173 function string_to_number, so that Fstring_to_number parses
20174 floating point numbers consistently with the Lisp reader.
20175 (digit_to_number): Move here from data.c. Make it static inline.
20176 (E_CHAR, EXP_INT): Remove, replacing with ...
20177 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20178 (string_to_number): New function, replacing isfloat_string.
20179 This function checks for valid syntax and produces the resulting
20180 Lisp float number too. Rework it so that string-to-number
20181 no longer mishandles examples like "1.0e+". Use strtoumax,
20182 so that overflow for non-base-10 numbers is reported only when
20183 there's no portable and simple way to convert to floating point.
20185 * textprop.c (set_text_properties_1): Rewrite for clarity,
20186 and to avoid GCC warning about integer overflow.
20188 * intervals.h (struct interval): Use EMACS_INT for members
20189 where EMACS_UINT might cause problems. See
20190 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20191 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20192 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20194 (offset_intervals): Tell GCC not to worry about length overflow
20195 when negating a negative length.
20197 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20198 (overrun_check_free): Likewise.
20200 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20201 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20204 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20205 (gnutls_make_error): Rename local to avoid shadowing.
20206 (gnutls_emacs_global_deinit): ifdef out; not used.
20207 (Fgnutls_boot): Use const for pointer to readonly storage.
20208 Comment out unused local. Fix pointer signedness problems.
20210 * lread.c (openp): Don't stuff size_t into an 'int'.
20211 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20212 about possible signed overflow.
20214 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20215 (GDK_KEY_g): Don't define if already defined.
20216 (xg_prepare_tooltip): Avoid pointer signedness problem.
20217 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20219 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20220 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20222 * xfns.c (Fx_window_property): Simplify a bit,
20223 to make a bit faster and to avoid GCC 4.6.0 warning.
20224 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20226 * fns.c (internal_equal): Don't assume size_t fits in int.
20228 * alloc.c (compact_small_strings): Tighten assertion a little.
20230 Replace pEd with more-general pI, and fix some printf arg casts.
20231 * lisp.h (pI): New macro, generalizing old pEd macro to other
20232 conversion specifiers. For example, use "...%"pI"d..." rather
20233 than "...%"pEd"...".
20234 (pEd): Remove. All uses replaced with similar uses of pI.
20235 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20236 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20237 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20238 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20239 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20240 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20241 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20243 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20244 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20245 * print.c (safe_debug_print, print_object): Likewise.
20246 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20248 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20249 avoiding the 0 flag, which is not portable.
20250 * process.c (Fmake_network_process): Use pI to avoid cast.
20251 * region-cache.c (pp_cache): Likewise.
20252 * xdisp.c (decode_mode_spec): Likewise.
20253 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20254 behavior on 64-bit hosts with printf arg.
20255 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20256 (x_stop_queuing_selection_requests): Likewise.
20257 (x_get_window_property): Don't truncate byte count to an 'int'
20260 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20261 here, since it parses constructs like leading '-' and spaces,
20262 which are not wanted; and it overflows with large numbers.
20263 Instead, simply match F[0-9]+, which is what is wanted anyway.
20265 * alloc.c: Remove unportable assumptions about struct layout.
20266 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20267 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20268 (allocate_vectorlike, make_pure_vector): Use the new macros,
20269 plus offsetof, to remove unportable assumptions about struct layout.
20270 These assumptions hold on all porting targets that I know of, but
20271 they are not guaranteed, they're easy to remove, and removing them
20272 makes further changes easier.
20274 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20275 This doesn't fix a bug but makes the code clearer.
20276 (string_overrun_cookie): Now const. Use initializers that
20277 don't formally overflow signed char, to avoid warnings.
20278 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20279 can cause Emacs to crash when string overrun checking is enabled.
20280 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20281 multiple of sizeof (EMACS_INT); it need not be, if
20282 alignof(EMACS_INT) < sizeof (EMACS_INT).
20283 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20285 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20287 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20289 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20291 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20292 supposed to be handshaking. (Bug#8556)
20293 Reported by Paul Eggert <eggert@cs.ucla.edu>.

20297 * lisp.h (Qdebug): List symbol.
20298 * eval.c (Qdebug): Restore global linkage.
20299 * keyboard.c (debug-on-event): New variable.
20300 (handle_user_signal): Break into debugger when debug-on-event
20301 matches the current signal symbol.
20303 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20305 * alloc.c (check_sblock, check_string_bytes)
20306 (check_string_free_list): Convert to standard C.
20308 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20310 * w32.c (emacs_gnutls_push): Fix typo.
20312 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20314 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20315 "cast to pointer from integer of different size".
20317 Improve doprnt and its use in verror. (Bug#8545)
20318 * doprnt.c (doprnt): Document the set of format control sequences
20319 supported by the function. Use SAFE_ALLOCA instead of always
20322 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20323 is one byte too soon. Don't use xrealloc; instead xfree and
20326 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20328 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20331 * gnutls.c: Renamed global_initialized to
20332 gnutls_global_initialized. Added internals for the
20333 :verify-hostname-error, :verify-error, and :verify-flags
20334 parameters of `gnutls-boot' and documented those parameters in the
20335 docstring. Start callback support.
20336 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20337 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20338 on error. Return error code.
20339 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20340 (emacs_gnutls_read): Likewise.
20341 (Fgnutls_boot): Return handshake error code.
20342 (emacs_gnutls_handle_error): New function.
20343 (wsaerror_to_errno): Likewise.
20345 * w32.h (emacs_gnutls_pull): Add prototype.
20346 (emacs_gnutls_push): Likewise.
20348 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
20349 (emacs_gnutls_push): Likewise.
20351 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
20353 * process.c (wait_reading_process_output): Check if GnuTLS
20354 buffered some data internally if no FDs are set for TLS
20357 * makefile.w32-in (OBJ2): Add gnutls.$(O).
20358 (LIBS): Link to USER_LIBS.

20363 * xdisp.c (handle_single_display_spec): Rename the
20364 display_replaced_before_p argument into display_replaced_p, to
20365 make it consistent with the commentary. Fix typos in the
20368 * textprop.c (syms_of_textprop): Remove dead code.

20374 to changes in oldXMenu/XMenu.h from 2011-04-16.
20375 <menu_help_message, prev_menu_help_message>: Constify.
20376 (IT_menu_make_room): menu->help_text is now `const char **';

20666 * process.c (send_process): Adjust to the new signatures of
20667 emacs_write and emacs_gnutls_write. Do not attempt to store

20861 * font.h (font_close_object): Remove.
20862 * fontset.c (FONTSET_OBJLIST): Remove.
20863 (free_realized_fontset) #if-0 the body, which does nothing.
20864 (face_suitable_for_char_p): #if-0, as it's never called.
20865 * fontset.h (face_suitable_for_char_p): Remove decl.
20866 * xfaces.c (face_at_string_position):
20867 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
20868 since 0 is always ASCII.
20870 * fns.c (weak_hash_tables): Now static.
20872 * fileio.c: Make symbols static if they're not exported.
20873 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

20887 * lisp.h (fatal_error_signal_hook): Remove decl.
20888 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.

20891 * editfns.c, lisp.h (get_operating_system_release): Remove.
20892 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20893 worth the hassle of breaking this out.
20895 * xterm.c: Make symbols static if they're not exported.
20896 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
20897 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

20997 * lisp.h: Remove these decls.
20999 * buffer.c (buffer_count): Remove unused var.
21001 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

21008 * atimer.h (run_all_atimers): Remove; not exported.
21010 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21011 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21012 was inaccessible from Lisp.
21013 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21014 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21016 alloc.c: Import and export fewer symbols, and remove unused items.
21017 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21019 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21020 it's not optimized away by whole-program optimization.

21022 (catchlist, handlerlist, mark_backtrace):
21023 Declare only if BYTE_MARK_STACK.

21032 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21033 (mark_backtrace): Define only if BYTE_MARK_STACK.
21034 * xdisp.c (message_enable_multibyte): Now static.
21036 Declare Lisp_Object Q* variables to be 'static' if not exported.
21037 This makes it easier for human readers (and static analyzers)
21038 to see whether these variables are used from other modules.
21039 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21040 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21041 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21049 Remove decls of unexported vars.
21050 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21052 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21054 Make Emacs functions such as Fatom 'static' by default.
21055 This makes it easier for human readers (and static analyzers)
21056 to see whether these functions can be called from other modules.
21057 DEFUN now defines a static function. To make the function external
21058 so that it can be used in other C modules, use the new macro DEFUE.
21059 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21060 (Finit_image_library):
21061 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21062 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21063 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21064 Remove decls, since these functions are now static.
21065 (Funintern, Fget_internal_run_time): New decls, since these functions
21066 were already external.
21068 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21069 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21075 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21076 Mark functions with DEFUE instead of DEFUN,
21077 if they are used in other modules.
21078 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21079 decls for now-static functions.
21080 * buffer.h (Fdelete_overlay): Remove decl.
21081 * callproc.c (Fgetenv_internal): Mark as internal.

21090 * image.c (Finit_image_library): New forward static decl.
21091 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21092 * intervals.h (Fprevious_property_change):
21093 (Fremove_list_of_text_properties): Remove decls.
21094 * keyboard.c (Fthis_command_keys): Remove decl.
21095 (Fcommand_execute): New forward static decl.

21111 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21113 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21116 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21118 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21119 when at ZV. (Bug#8487)
21121 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21123 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21126 * sound.c (sound_cleanup, alsa_close): Likewise.
21127 * termcap.c (tgetent): Likewise.
21128 * xfns.c (x_default_font_parameter): Likewise.
21129 * xsettings.c (read_and_apply_settings): Likewise.
21131 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21132 (overrun_check_free): Protoize.
21134 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21136 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21137 since callers should never pass a negative size.
21138 Change the signature to match that of plain 'read' and 'write'; see
21139 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21140 * lisp.h: Update prototypes of emacs_write and emacs_read.
21142 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21144 * xdisp.c (redisplay_window): Don't try to determine the character
21145 position of the scroll margin if the window start point w->startp
21146 is outside the buffer's accessible region. (Bug#8468)
21148 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21150 Fix write-region and its subroutines for buffers > 2GB.
21151 * fileio.c (a_write, e_write): Modify declaration of arguments and
21152 local variables to support buffers larger than 2GB.
21153 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21155 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21156 argument, local variables, and return value.
21158 * lisp.h: Update prototypes of emacs_write and emacs_read.
21160 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21162 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21164 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21166 Fix more problems found by GCC 4.6.0's static checks.
21168 * xdisp.c (vmessage): Use a better test for character truncation.
21170 * charset.c (load_charset_map): <, not <=, for optimization,
21171 and to avoid potential problems with integer overflow.
21172 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21173 * casetab.c (set_identity, shuffle): Likewise.
21174 * editfns.c (Fformat): Likewise.
21175 * syntax.c (skip_chars): Likewise.
21177 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21178 This also lets GCC 4.6.0 generate slightly better loop code.
21180 * callint.c (Fcall_interactively): <, not <=, for optimization.
21181 (Fcall_interactively): Count the number of arguments produced,
21182 not the number of arguments given. This is simpler and lets GCC
21183 4.6.0 generate slightly better code.
21185 * ftfont.c: Distingish more carefully between FcChar8 and char.
21186 The previous code passed unsigned char * to a functions like
21187 strlen and xstrcasecmp that expect char *, which does not
21188 conform to the C standard.
21189 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21190 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21191 char * when the C standard requires it.
21193 * keyboard.c (read_char): Remove unused var.
21195 * eval.c: Port to Windows vsnprintf (Bug#8435).
21196 Include <limits.h>.
21197 (SIZE_MAX): Define if the headers do not.
21198 (verror): Do not give up if vsnprintf returns a negative count.
21199 Instead, grow the buffer. This ports to Windows vsnprintf, which
21200 does not conform to C99. Problem reported by Eli Zaretskii.
21201 Also, simplify the allocation scheme, by avoiding the need for
21202 calling realloc, and removing the ALLOCATED variable.
21204 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21206 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21207 But keep the doprint source code for now, as we might revamp it
21208 and use it again (Bug#8435).
21209 * lisp.h (doprnt): Remove.
21210 * Makefile.in (base_obj): Remove doprnt.o.
21211 * deps.mk (doprnt.o): Remove.
21213 error: Print 32- and 64-bit integers portably (Bug#8435).
21214 Without this change, on typical 64-bit hosts error ("...%d...", N)
21215 was used to print both 32- and 64-bit integers N, which relied on
21216 undefined behavior.
21217 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21218 * lisp.h (error, verror): Mark as printf-like functions.
21219 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21220 Report overflow in size calculations when allocating printf buffer.
21221 Do not truncate output string at its first null byte.
21222 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21223 Truncate the output at a character boundary, since vsnprintf does not
21225 * charset.c (check_iso_charset_parameter): Convert internal
21226 character to string before calling 'error', since %c now has the
21228 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21229 overflow when computing char to be passed to 'error'. Do not
21230 pass Lisp_Object to 'error'; pass the integer instead.
21231 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21232 formatted with plain %d.
21234 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21236 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21238 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21240 * xterm.c (x_catch_errors): Remove duplicate declaration.
21242 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21244 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21246 2011-04-10 Jim Meyering <meyering@redhat.com>
21248 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21249 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21250 return ssize_t not "int", and use size_t as the buffer length.
21251 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21252 * gnutls.h: Update declarations.
21253 * process.c (read_process_output): Use ssize_t, to match.
21254 (send_process): Likewise.
21256 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21258 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21260 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21262 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21263 Use unsigned char, to match FcChar8 type definition.
21265 * xterm.c (handle_one_xevent):
21266 * xmenu.c (create_and_show_popup_menu):
21267 * xselect.c (x_decline_selection_request)
21268 (x_reply_selection_request): Avoid type-punned deref of X events.
21270 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21272 Fix some uses of `int' instead of EMACS_INT.
21273 * search.c (string_match_1, fast_string_match)
21274 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)

21366 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21368 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21369 This avoids several warnings with gcc -Wstrict-overflow.
21370 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21371 directly, rather than having caller test rule sign. This avoids
21372 some unnecessary tests.
21373 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21374 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21375 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21377 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21378 (xfont_open): Avoid unnecessary tests.
21380 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21382 * composite.h, composite.c (composition_gstring_put_cache):
21383 Use EMACS_INT, not int, for length.
21385 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21386 breaking out part of COMPOSITION_DECODE_RULE.
21387 (COMPOSITION_DECODE_RULE): Use it.
21388 * composite.c (get_composition_id): Remove unused local vars,
21389 by using the new macro.
21391 * textprop.c (set_text_properties_1): Change while to do-while,
21392 since the condition is always true at first.
21394 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21395 (interval_deletion_adjustment): Return unsigned value.
21398 * process.c (list_processes_1, create_pty, read_process_output):

21400 (create_pty): Remove unnecessary "volatile"s.
21401 (Fnetwork_interface_info): Avoid possibility of int overflow.

21414 * print.c (print_error_message): Avoid int overflow.
21416 * font.c (font_list_entities): Redo for clarity,
21417 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21419 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21420 (font_score): Avoid potential overflow in diff calculation.

21425 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21427 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21428 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21429 can always succeed if overflow has undefined behavior.
21431 * search.c (boyer_moore, wordify): Remove vars set but not used.
21432 (wordify): Omit three unnecessary tests.
21434 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21443 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21444 (Finsert_file_contents): Remove unnecessary code checking fd.
21446 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21447 Check for integer overflow on size calculations.
21449 * buffer.c (Fprevious_overlay_change): Remove var that is set
21452 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21453 Remove vars that are set but not used.
21454 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21455 (timer_check_2): Mark vars as initialized.
21457 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21459 * image.c (lookup_image): Remove var that is set but not used.
21460 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21462 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21463 that are set but not used.
21465 * xfns.c (make_invisible_cursor): Don't return garbage
21466 if XCreateBitmapFromData fails (Bug#8410).
21468 * xselect.c (x_get_local_selection, x_handle_property_notify):
21469 Remove vars that are set but not used.
21471 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21472 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21474 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21475 Remove var that is set but not used.
21476 (scroll_bar_windows_size): Now size_t, not int.
21477 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21478 Check for overflow.
21480 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21481 (map_tty_color) [!defined MSDOS]: Likewise.
21483 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21485 * coding.c: Remove vars that are set but not used.
21486 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21487 All callers changed.
21488 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21489 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21490 (decode_coding_charset): Remove vars that are set but not used.
21492 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21493 that is set but not used.
21495 * print.c (print_object): Remove var that is set but not used.
21497 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21498 The gnulib version avoids calling malloc in the usual case,
21499 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21500 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21501 * filelock.c (current_lock_owner): Likewise.
21502 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21503 * sysdep.c: Include allocator.h, careadlinkat.h.
21504 (emacs_no_realloc_allocator): New static constant.
21505 (emacs_readlink): New function.
21506 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21507 ../lib/careadlinkat.h.
21509 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21511 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21512 first non-nil return value).
21514 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21516 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21517 if not defined (Bug#8403).
21519 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21521 * xdisp.c (display_count_lines): Remove parameter `start',
21522 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21523 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21524 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21526 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21527 and thereabouts. All callers changed.
21528 (get_per_char_metric): Remove parameter `f', unused since
21529 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21531 2011-04-02 Jim Meyering <meyering@redhat.com>
21533 do not dereference NULL upon failed strdup
21534 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21535 (ns_get_family): Likewise.
21537 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21539 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21541 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21543 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21546 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21548 Add lexical binding.
21550 * window.c (Ftemp_output_buffer_show): New fun.
21551 (Fsave_window_excursion):
21552 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21554 * lread.c (lisp_file_lexically_bound_p): New function.
21555 (Fload): Bind Qlexical_binding.
21556 (readevalloop): Remove `evalfun' arg.
21557 Bind Qinternal_interpreter_environment.
21558 (Feval_buffer): Bind Qlexical_binding.
21559 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21561 (syms_of_lread): Declare `lexical-binding'.
21563 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21565 * keyboard.c (eval_dyn): New fun.
21566 (menu_item_eval_property): Use it.
21568 * image.c (parse_image_spec): Use Ffunctionp.
21570 * fns.c (concat, mapcar1): Accept byte-code-functions.
21572 * eval.c (Fsetq): Handle lexical vars.
21573 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21574 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21575 (FletX, Flet): Obey lexical binding.
21576 (Fcommandp): Handle closures.
21577 (Feval): New `lexical' arg.
21578 (eval_sub): New function extracted from Feval. Use it almost
21579 everywhere where Feval was used. Look up vars in lexical env.
21581 (Ffunctionp): Move from subr.el.
21582 (Ffuncall): Handle closures.
21583 (apply_lambda): Remove `eval_flags'.
21584 (funcall_lambda): Handle closures and new byte-code-functions.
21585 (Fspecial_variable_p): New function.
21586 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21587 but without exporting it to Lisp.
21589 * doc.c (Fdocumentation, store_function_docstring):
21590 * data.c (Finteractive_form): Handle closures.
21592 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21595 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21597 (exec_byte_code): New function extracted from Fbyte_code to handle new
21598 calling convention for byte-code-functions. Add new byte-codes.
21600 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21602 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21604 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21606 * xdisp.c (redisplay_internal): Fix prototype.
21608 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21610 * xdisp.c (SCROLL_LIMIT): New macro.
21611 (try_scrolling): Use it when setting scroll_limit.
21612 Limit scrolling to 100 screen lines.
21613 (redisplay_window): Even when falling back on "recentering",
21614 position point in the window according to scroll-conservatively,
21615 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21617 (try_scrolling): When point is above the window, allow searching
21618 as far as scroll_max, or one screenful, to compute vertical
21619 distance from PT to the scroll margin position. This prevents
21620 try_scrolling from unnecessarily failing when
21621 scroll-conservatively is set to a value slightly larger than the
21622 window height. Clean up the case of PT below the margin at bottom
21623 of window: scroll_max can no longer be INT_MAX. When aggressive
21624 scrolling is in use, don't let point enter the opposite scroll
21625 margin as result of the scroll.
21626 (syms_of_xdisp) <scroll-conservatively>: Document the
21627 threshold of 100 lines for never-recentering scrolling.
21629 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21631 * dispextern.h (move_it_by_lines):
21632 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21633 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21634 (message_log_check_duplicate): Remove parameters `prev_bol' and
21635 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21636 (redisplay_internal): Remove parameter `preserve_echo_area',
21637 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21639 * indent.c (Fvertical_motion):
21640 * window.c (window_scroll_pixel_based, Frecenter):
21641 Don't pass `need_y_p' to `move_it_by_lines'.
21643 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21645 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21646 steal a few bits to be more compact.
21647 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21648 Remove unneeded casts.
21650 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21652 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21654 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21655 binding" message (bug#7967).
21657 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21659 Fix more problems found by GCC 4.6.0's static checks.
21661 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21662 Remove unused local var.
21664 * editfns.c (Fmessage_box): Remove unused local var.
21666 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21667 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21668 Omit unused local vars.
21669 * window.c (shrink_windows): Omit unused local var.
21670 * menu.c (digest_single_submenu): Omit unused local var.
21671 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21672 Omit unused local var.
21674 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21675 Don't assume string length fits in int.
21676 (keyremap_step, read_key_sequence): Use size_t for sizes.
21677 (read_key_sequence): Don't check last_real_key_start redundantly.
21679 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21680 instead of alloca (Bug#8344).
21682 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21683 (Fbacktrace_frame): Don't assume nframes fits in int.
21685 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21687 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21690 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21692 * cm.c (calccost): Turn while-do into do-while, for clarity.
21694 * keyboard.c (syms_of_keyboard): Use the same style as later
21695 in this function when indexing through an array. This also
21696 works around GCC bug 48267.
21698 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21700 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21702 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21703 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21705 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21706 This avoids undefined behavior on integer overflow, and is a bit
21707 more convenient anyway since it is compared to a size_t variable.
21709 Variadic C functions now count arguments with size_t, not int.
21710 This avoids an unnecessary limitation on 64-bit machines, which
21711 caused (substring ...) to crash on large vectors (Bug#8344).
21712 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21713 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21714 All variadic functions and their callers changed accordingly.

21720 (funcall_lambda, mark_backtrace): Likewise.
21721 * fns.c (concat): Likewise.
21722 * frame.c (x_set_frame_parameters): Likewise.
21723 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21724 0 if not found, not -1. All callers changed.
21726 * alloc.c (garbage_collect): Don't assume stack size fits in int.

21934 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21936 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

21941 Fix more problems found by GCC 4.5.2's static checks.
21943 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21944 the first time through the loop, since we know p0 < p1 then.
21945 This also avoids a gcc -Wstrict-overflow warning.
21947 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21948 leading to a memory leak, possible in functions like
21949 load_charset_map_from_file that can allocate an unbounded number
21950 of objects (Bug#8318).
21952 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21953 that could (at least in theory) be that large.
21955 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21956 This is less likely to overflow, and avoids undefined behavior if
21957 overflow does occur. All callers changed. Use strtoul to scan
21958 for the unsigned long integer.

21975 * process.c (Fmake_network_process): Use socklen_t, not int,
21976 where POSIX says socklen_t is required in portable programs.
21977 This fixes a porting bug on hosts like 64-bit HP-UX, where
21978 socklen_t is wider than int (Bug#8277).
21979 (Fmake_network_process, server_accept_connection):
21980 (wait_reading_process_output, read_process_output):
21983 * process.c: Rename or move locals to avoid shadowing.

21993 Make tparam.h and terminfo.c consistent.
21994 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21995 Include tparam.h instead, since it declares them.
21996 * cm.h (PC): Remove extern decl; tparam.h now does this.
21997 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21998 * terminfo.c: Include tparam.h, to check interfaces.
21999 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22000 (tparam): Adjust signature to match interface in tparam.h;
22001 this removes some undefined behavior. Check that outstring and len
22002 are zero, which they always are with Emacs.
22003 * tparam.h (PC, BC, UP): New extern decls.
22005 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22006 (xftfont_open): Rename locals to avoid shadowing.

22024 (composition_update_it): Mark var as initialized.
22025 (find_automatic_composition): Mark vars as initialized,
22026 with a FIXME (Bug#8290).

22032 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22033 to avoid shadowing.

22045 Fix pointer signedness.
22046 (alsa_choose_format): Remove unused local var.
22047 (wav_play): Initialize a variable to 0, to prevent undefined
22048 behavior (Bug#8278).
22050 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22052 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22054 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22055 clobbering (Bug#8298).
22056 * sysdep.c (sys_subshell): Likewise.
22057 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22059 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22060 This should get cleaned up, so that child_setup has the
22061 same signature on all platforms.
22063 * callproc.c (call_process_cleanup): Now static.
22064 (relocate_fd): Rename locals to avoid shadowing.
22066 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22068 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22069 not to be necessary, and produces flickering.
22071 2011-03-20 Glenn Morris <rgm@gnu.org>
22073 * config.in: Remove file.
22075 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22120 Define only if needed.
22122 * unexelf.c (unexec): Name an expression,
22123 to avoid gcc -Wbad-function-cast warning.
22124 Use a different way to cause a compilation error if anyone uses
22125 n rather than nn, a way that does not involve shadowing.
22126 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22128 * deps.mk (unexalpha.o): Remove; unused.

22193 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22194 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22195 some of which prompt warnings from gcc -Wbad-function-cast.
22196 (Fformat_time_string, Fencode_time, Finsert_char):
22197 (Ftranslate_region_internal, Fformat):

22225 (Fmemory_limit): Cast sbrk's returned value to char *.
22227 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22228 avoids undefined behavior in theory.
22230 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22232 Use functions, not macros, for up- and down-casing (Bug#8254).
22233 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22234 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22235 to use the following functions instead of these macros.
22236 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22237 EMACS_INT, since callers assume the returned value fits in int.
22238 (upcase1): Likewise, for UPCASE_TABLE.
22239 (uppercasep, lowercasep, upcase): New static inline functions.
22240 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22250 (regex_compile, re_match_2_internal): Mark locals as initialized.
22251 (RETALLOC_IF): Define only if needed.
22252 (WORDCHAR_P): Likewise. This one is never needed, but is used
22253 only in a comment talking about a compiler bug, so put inside
22254 the #if 0 of that comment.
22255 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22256 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22282 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22283 New macros, so that the caller can use some names other than
22284 gcpro1, gcpro2, etc.
22285 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22287 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22288 argument, for consistency with GCPRO2_VAR, etc: it is now the
22289 prefix of the variable, not the variable itself. All uses
22291 * dired.c (directory_files_internal, file_name_completion):
22292 Rename locals to avoid shadowing.
22294 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22295 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22296 dired.c's scmp function, had undefined behavior.
22297 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22298 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22299 * buffer.h: ... to here, because these macros use current_buffer,
22300 and the new implementation with inline functions needs to have
22301 current_buffer in scope now, rather than later when the macros
22303 (downcase, upcase1): New static inline functions.
22304 (DOWNCASE, UPCASE1): Reimplement using these functions.
22305 This avoids undefined behavior in expressions like
22306 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22307 from race conditions in accessing the global variables
22308 case_temp1 and case_temp2.
22309 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22310 * lisp.h (case_temp1, case_temp2): Remove their decls.
22311 * character.h (ASCII_CHAR_P): Move from here ...
22312 * lisp.h: ... to here, so that the inline functions mentioned
22313 above can use them.
22315 * dired.c (directory_files_internal_unwind): Now static.
22317 * fileio.c (file_name_as_directory, directory_file_name):

22320 (file_name_as_directory): Use const pointers when appropriate.
22321 (Fexpand_file_name): Likewise. In particular, newdir might
22322 point at constant storage, so make it a const pointer.
22323 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22324 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22326 (Fset_file_times, Finsert_file_contents, auto_save_error):

22331 to avoid shadowing.
22333 * marker.c (bytepos_to_charpos): Remove; unused.
22335 * lisp.h (verify_bytepos, count_markers): New decls,
22336 so that gcc does not warn that these functions aren't declared.
22338 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22339 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22340 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22341 (copy_text): Remove unused local var.

22344 (lock_file_1): Rename local to avoid shadowing.
22346 * buffer.c (fix_overlays_before): Mark locals as initialized.
22347 (fix_start_end_in_overlays): Likewise. This function should be
22348 simplified by using pointers-to-pointers, but that's a different

22351 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22352 (report_overlay_modification): Rename locals to avoid shadowing.

22357 to suppress a gcc -Wclobbered warning that does not seem to be right.
22358 (MAXPATHLEN): Define only if needed.
22360 * process.c (serial_open, serial_configure): Move decls from here ...
22361 * systty.h: ... to here, so that they can be checked.
22363 * fns.c (get_random, seed_random): Move extern decls from here ...
22364 * lisp.h: ... to here, so that they can be checked.
22366 * sysdep.c (reset_io): Now static.

22375 (describe_map_tree):
22376 Rename locals to avoid shadowing.
22378 * keyboard.c: Declare functions static if they are not used elsewhere.

22526 1152921504606846976) returns the obviously-bogus value (-948597
22527 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22528 reports time overflow. See
