66
67 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
68

106 Adjust comment.
107 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

111
112 2013-03-07 Eli Zaretskii <eliz@gnu.org>

185 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
186
187 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
188 * sysdep.c (list_system_processes)
189 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
190 Make it a stub in this case; otherwise the build might fail,
191 and this code hasn't been tested on such hosts anyway.
192 Problem reported by Nelson H. F. Beebe in
193 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
194 and analyzed by Jérémie Courrèges-Anglas in
195 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
196
197 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
198

204
205 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
206
207 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
208 * filelock.c: Include <c-ctype.h>.
209 (MAX_LFINFO): New top-level constant.
210 (lock_info_type): Remove members pid, boot_time. Add members at,
211 dot, colon. Change user member to be the entire buffer, not a
212 pointer. This allows us to handle the case where a foreign
213 pid or boot time exceeds the local range. All uses changed.
214 (LINKS_MIGHT_NOT_WORK): New constant.
215 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
216 (defined_WINDOWSNT): Remove.
217 (MAKE_LOCK_NAME, file_in_lock_file_name):
218 Always use .#FILE (not .#-FILE) for the file lock,
219 even if it is a regular file.
220 (rename_lock_file): New function.
221 (create_lock_file): Use it.
222 (create_lock_file, read_lock_data):
223 Prefer a symbolic link for the lock file, falling back on a
224 regular file if symlinks don't work. Do not try to create
225 symlinks on MS-Windows, due to security hassles. Stick with
226 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
227 link, rename, unlink, mkstemp) when creating locks, as a GNUish
228 host may be using a Windowsish file system, and cannot use
229 MS-Windows-only system calls. Fall back on mktemp if mkstemp
230 doesn't work. Don't fail merely because of a symlink-contents
231 length limit in the current file system; fall back on regular
232 files. Increase the symlink contents length limit to 8 KiB, this
233 should be big enough for any real use and doesn't crunch the
234 stack.
235 (create_lock_file, lock_file_1, read_lock_data):
236 Simplify allocation of lock file buffers now that they fit in 8 KiB.
237 (lock_file_1): Return error number, not bool. All callers changed.
238 (ELOOP): New macro, if not already defined.
239 (read_lock_data): Return size of lock file contents, not Lisp object.
240 All callers changed. Handle a race condition if some other process
241 replaces a regular-file lock with a symlink lock or vice versa,
242 while we're trying to read the lock.
243 (current_lock_owner): Parse contents more carefully, to help avoid
244 confusing a regular-file lock with some other application's use
245 of the file. Check for lock file contents being too long, or
246 not parsing correctly.
247 (current_lock_owner, lock_file):
248 Allow foreign pid and boot times that exceed the local range.
249 (current_lock_owner, lock_if_free, lock_file):
250 Simplify allocation of lock file contents.
251 * w32.c (sys_rename_replace): New function, containing most of
252 the contents of the old sys_rename.
253 (sys_rename): Use it.
254 (fchmod): New dummy function.
255 * w32.h (sys_rename_replace, fchmod): New decls.
256
257 2013-03-05 Eli Zaretskii <eliz@gnu.org>
258
259 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
260 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
261 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
262 <dmantipov@yandex.ru>.
263
264 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
265
266 * composite.c (get_composition_id, fill_gstring_header):
267 Use make_uninit_vector where appropriate.
268 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
269 * xselect.c (clean_local_selection_data): Likewise.
270
271 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
272
273 Fix misuse of ImageMagick that caused core dump (Bug#13846).
274 * image.c (imagemagick_load_image): Calculate height and width
275 after flattening the image, not before.
276
277 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
278
279 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
280 * ftfont.c (ftfont_shape_by_flt): Likewise.
281 * w32uniscribe.c (uniscribe_shape): Likewise.
282
283 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
284
285 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
286 The old approach, which fell back on DIR/.#FILE.0 through
287 DIR/.#FILE.9, had race conditions that could not be easily fixed.
288 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
289 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
290 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
291 because the locking mechanism was never reliable in that case).
292 This patch fixes this and other bugs discovered by a code
293 inspection that was prompted by
294 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
295 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
296 to avoid interoperability problems between the MS-Windows and
297 non-MS-Windows implementations. MS-Windows and non-MS-Windows
298 instances of Emacs now ignore each others' locks.
299 * filelock.c (defined_WINDOWSNT): New constant.
300 (MAKE_LOCK_NAME, fill_in_lock_file_name):
301 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
302 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
303 regular files on MS-Windows hosts.
304 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
305 Use SAFE_ALLOCA to avoid problems with long file names.
306 (MAX_LFINFO): Now a local constant, not a global macro.
307 (IS_LOCK_FILE): Remove.
308 (lock_file_1): Don't inspect errno if symlink call succeeds;
309 that's not portable.
310 (lock_file): Document that this function can return if lock
311 creation fails.
312 (lock_file): Don't access freed storage.
313
314 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
315
316 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
317
318 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
319
320 * textprop.c: Use bool for booleans.
321 (validate_interval_range, Fadd_text_properties)
322 (Fremove_text_properties): Prefer bool to int when either works.
323
324 2013-03-02 Eli Zaretskii <eliz@gnu.org>
325
326 * textprop.c (Fadd_text_properties, Fremove_text_properties):
327 If the interval tree changes as a side effect of calling
328 modify_region, re-do processing starting from the call to
329 validate_interval_range. (Bug#13743)
330
331 2013-02-28 Eli Zaretskii <eliz@gnu.org>
332
333 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
334 (Bug#13546).
335
336 2013-02-27 Eli Zaretskii <eliz@gnu.org>
337
338 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
339 _SH_DENYRW flag, instead of emacs_open, to deny any other process
340 access to the lock file until it is written and closed.
341 (Bug#13807)
342
343 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
344

350
351 * window.c (Frecenter): Tiny docstring enhancement.
352
353 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
354
355 Minor textprop integer cleanup.
356 * intervals.h, textprop.c (add_text_properties_from_list):
357 Return void, not int, since nobody uses the return value.
358 * textprop.c (validate_plist, add_properties, remove_properties)
359 (Fadd_text_properties):
360 Don't assume list length fits in int.
361 (interval_has_all_properties, interval_has_some_properties)
362 (interval_has_some_properties_list, add_properties, remove_properties)
363 (Fadd_text_properties, Fremove_text_properties)
364 (Fremove_list_of_text_properties, text_property_stickiness):
365 Use bool for booleans.
366 (Fadd_text_properties, Fremove_text_properties):
367 (Fremove_list_of_text_properties):
368 Reindent do-while as per GNU style.
369

371
372 Implement CLASH_DETECTION for MS-Windows.
373
374 * filelock.c [WINDOWSNT]: Include w32.h.
375 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
376 function of that name. Up-case the macro arguments.
377 (IS_LOCK_FILE): New macro.
378 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
379 (create_lock_file): New function, with body extracted from
380 lock_file_1.
381 [WINDOWSNT]: Implement lock files by writing a regular file with
382 the lock information as its contents.
383 (read_lock_data): New function, on Posix platforms just calls
384 emacs_readlinkat.
385 [WINDOWSNT]: Read the lock info from the file.
386 (current_lock_owner): Call read_lock_data instead of calling
387 emacs_readlinkat directly.
388 (lock_file) [WINDOWSNT]: Run the file name through
389 dostounix_filename.
390
391 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
392 just check if the process by that PID exists.
393
394 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
395 also present, as doing so will fail to error out if the file
396 already exists.
397
398 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
399
400 * textprop.c (Fadd_text_properties, Fremove_text_properties)
401 (Fremove_list_of_text_properties): Skip all of the intervals in
402 the region between START and END that already have resp. don't
403 have the requested properties, not just the first one.
404 Add assertions that the loop afterwards always modifies the
405 properties. (Bug#13743)
406
407 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
408

412
413 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>

416 This is a followon simplification to the fix for Bug#13650.
417 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
418 (START_FILES): Remove. All uses removed.
419 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
420 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
421 (buildobj.h): Use it.
422 ($(ALLOBJS)): Depend on globals.h.
423 (temacs$(EXEEXT)): Use $(ALLOBJS).

435 * vm-limit.c: Move most of mem-limits.h's contents here.
436 (data_start): New decl. It's OK if this is approximate,
437 so simplify-away some unnecessary exactness.
438 (POINTER): Remove; all uses removed.
439 (data_space_start): Now char *, to avoid casts.
440 (exceeds_lisp_ptr): New function, replacing the old
441 EXCEEDS_LISP_PTR macro. All uses changed.
442 (check_memory_limits): Simplify and remove casts.
443 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

457 and diagnosed by Andreas Schwab in
458 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
459
460 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
461
462 Assume C89 or better.
463 * ralloc.c (SIZE, POINTER, NIL):
464 * vm-limit.c (POINTER):

469
470 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

485
486 2013-02-19 Daniel Colascione <dancol@dancol.org>
487
488 * sheap.c (report_sheap_usage): Use message, not message1, so
489 that we don't try to create a buffer while we're in the middle
490 of dumping Emacs. Explain why.
491

506
507 2013-02-19 Eli Zaretskii <eliz@gnu.org>
508
509 * w32proc.c (new_child): Avoid leaking handles if the subprocess

511
512 2013-02-17 Eli Zaretskii <eliz@gnu.org>
513
514 * xdisp.c (x_draw_vertical_border): For a window that is neither
515 the leftmost nor the rightmost, redraw both the left and the right
516 vertical borders. (Bug#13723)
517
518 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

532
533 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
534 * frame.c (syms_of_frame): ... to here.
535
536 2013-02-16 Eli Zaretskii <eliz@gnu.org>
537
538 * w32.c (sys_chown): Remove unused function.
539

541 unconditionally. (Bug#9066)
542
543 * w32.c (set_errno): Reset h_errno and don't set it to any other
544 value. Set errno instead.
545 (check_errno): Reset h_errno.

556
557 2013-02-15 Eli Zaretskii <eliz@gnu.org>
558
559 * keyboard.c (read_char): Fix calculation of auto-save time out
560 when auto-save-timeout is less than 4. (Bug#13720)
561
562 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
563 time. Improve diagnostics in DebPrint. (Bug#13546)
564
565 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
566 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
567 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
568 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,

574
575 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
576

588
589 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
590
591 Fix AIX port (Bug#13650).
592 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
593 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
594 was #undeffed earlier, so it cannot be used as a macro here.
595 Use the constant and not the macro.
596
597 2013-02-15 Eli Zaretskii <eliz@gnu.org>
598
599 * w32proc.c (new_child): If no vacant slots are found in
600 child_procs[], make another pass looking for slots whose process
601 has exited or died. (Bug#13546)
602
603 * w32.c (sys_pipe): When failing due to file descriptors above
604 MAXDESC, set errno to EMFILE.
605 (_sys_read_ahead): Update cp->status when failing to read serial
606 communications input, so that the status doesn't stay at
607 STATUS_READ_IN_PROGRESS. (Bug#13546)
608
609 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
610
611 * gtkutil.c (tb_size_cb): New function.
612 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
613
614 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
615
616 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
617 an event.
618
619 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
620
621 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
622
623 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
624
625 * font.c (font_range): Add pos_byte argument. Adjust comment
626 and break long line.
627 * font.h (font_range): Adjust prototype.
628 * composite.c (autocmp_chars): Pass byte position to font_range.

630
631 2013-02-13 Glenn Morris <rgm@gnu.org>
632
633 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
634
635 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
636
637 Improve AIX port some more (Bug#13650).
638 With this, it should be as good as it was in 23.3, though it's
639 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
640 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
641 * unexaix.c (start_of_text): Remove.
642 (_data, _text): Declare as char[], not int, as AIX manual suggests.
643 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
644 (orig_load_scnptr, orig_data_scnptr):
645 Now off_t, not long, since they are file offsets.
646 (make_hdr): Use _data, not start_of_data ().
647 This is the key part of the fix.
648 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
649 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
650
651 * pre-crt0.c (data_start): Initialize to 1.
652 This ports to compilers that optimize the external declaration
653 'int x = 0;' as if it were 'int x;' to shrink the executable.
654
655 Improve AIX port (Bug#13650).
656 This doesn't fix the bug, but it makes progress: Emacs builds now.
657 * unexaix.c: Include inttypes.h, stdarg.h.
658 (report_error, report_error_1): Mark as _Noreturn.
659 (report_error): Don't report the wrong errno.
660 (report_error_1): Now varargs. All callers changed.
661 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
662 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
663 (write_ptr): Use %p to print address rather than %lx and a cast
664 to unsigned long. Grow buffer a bit, to be safer.
665
666 2013-02-13 Eli Zaretskii <eliz@gnu.org>
667
668 * bidi.c (bidi_resolve_neutral): After finding the next
669 non-neutral character, accept NEUTRAL_ON type as well, because
670 directional control characters, such as LRE and RLE, have their
671 type converted to that by bidi_resolve_weak. This avoids aborts
672 when LRE/RLE follows a run of neutrals.
673 (bidi_move_to_visually_next): Assert that return value of
674 bidi_peek_at_next_level is non-negative. Negative values will
675 cause an infloop.
676
677 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
678
679 Minor getenv-related fixes.
680 * callproc.c (Fcall_process_region) [!DOS_NT]:
681 Avoid unnecessary duplicate call to getenv.
682 * callproc.c (init_callproc):
683 * dispnew.c (init_display):
684 * sysdep.c (sys_subshell):
685 Omit unnecessary cast of getenv or egetenv.
686
687 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
688
689 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
690 Update dependencies.
691
692 2013-02-12 Eli Zaretskii <eliz@gnu.org>
693
694 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
695 marker's position.
696 (display_line): Set w->region_showing to the value of
697 it->region_beg_charpos, not to -1. This fixes redisplay
698 optimization when cursor is moved up after M->. (Bug#13623)
699 (Bug#13626)
700 (try_scrolling): Scroll text up more if point is too close to ZV
701 and inside the scroll margin. This makes sure point is moved
702 outside the scroll margin in these cases.
703
704 * window.h (struct window): region_showing can no longer be
705 negative.
706
707 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
708
709 Tune by using memchr and memrchr.
710 * doc.c (Fsnarf_documentation):
711 * fileio.c (Fsubstitute_in_file_name):
712 * search.c (find_newline, scan_newline):
713 * xdisp.c (pos_visible_p, display_count_lines):
714 Use memchr and memrchr rather than scanning byte-by-byte.
715 * search.c (find_newline): Rename from scan_buffer.
716 Omit first arg TARGET, as it's always '\n'. All callers changed.
717
718 Clean up read_key_sequence a tiny bit more.
719 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
720 (read_key_sequence): Remove unused locals.
721
722 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
723
724 Clean up read_key_sequence a bit; reread active keymaps after first event.
725 * keyboard.c (read_char, read_char_x_menu_prompt)
726 (read_char_minibuf_menu_prompt):
727 Replace nmaps+maps with a single `map' arg.
728 (follow_key): Operate on a single map.
729 (active_maps): New function.
730 (test_undefined): Also return true for nil bindings.
731 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
732 a single (composed) keymap. Remember `first_event' to choose the right
733 set of active keymaps. Recompute the set of keymaps after receiving
734 the first event. Remove GOBBLE_FIRST_EVENT.
735 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
736 * keyboard.h (read_char): Update declaration.
737 * lread.c (read_filtered_event): Adjust call to read_char.
738
739 2013-02-11 Eli Zaretskii <eliz@gnu.org>
740
741 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
742 Don't use the limitation on backwards movement when lines are truncated
743 in the window. (Bug#13675)
744
745 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
746
747 * marker.c (set_marker_internal): If desired position is passed
748 as a marker, avoid call to buf_charpos_to_bytepos.
749 * window.c (Fset_window_point): Omit redundant type checking.
750 (Fset_window_start): Likewise. Format comment.
751 (window_scroll_pixel_based): Use set_marker_restricted_both
752 with character and byte positions obtained from an iterator.
753 (Fset_window_configuration): Use set_marker_restricted_both.
754 * xdisp.c (message_dolog): Likewise.
755
756 2013-02-10 Eli Zaretskii <eliz@gnu.org>
757
758 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
759 When text lines are longer than window's screen lines, don't move back
760 too far. This speeds up some redisplay operations. (Bug#13675)
761
762 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
763
764 * syntax.c (scan_sexps_forward): Fix byte position calculation

766
767 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
768
769 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
770 that was not needed.
771
772 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
773
774 Minor hashing refactoring.
775 * fns.c (SXHASH_REDUCE): Move to lisp.h.
776 (sxhash_float): Return EMACS_UINT, for consistency with the other
777 hash functions.
778 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
779 non-static inline function and therefore can't use static vars.
780 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
781 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
782 with the other hash functions.
783
784 2013-02-09 Eli Zaretskii <eliz@gnu.org>
785
786 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
787 XXXXXX part of the temporary file pattern is not downcased even
788 when w32-downcase-file-names is non-nil. (Bug#13661)

799
800 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
801
802 * search.c (scan_buffer): Calculate end byte position just once.
803 (scan_newline): Do not recalculate start_byte.
804 (search_command): Use eassert.
805 * syntax.c (struct lisp_parse_state): New member location_byte.
806 (scan_sexps_forward): Record from_byte and avoid redundant
807 character to byte position calculation ...
808 (Fparse_partial_sexp): ... here. Break too long line.
809
810 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
811

828
829 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
830
831 * coding.c (Fdefine_coding_system_internal): Use AREF where

866 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
867 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
868 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
869 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
870 (syms_of_nsterm): Add ns-use-native-fullscreen.
871
872 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
873
874 * fileio.c (Qchoose_write_coding_system): Now static.
875
876 2013-02-04 Eli Zaretskii <eliz@gnu.org>
877
878 * xdisp.c (window_buffer_changed): region_showing can be negative,
879 which still means region is being displayed.
880 (redisplay_internal): Resurrect code that forced redisplay of the
881 whole window when showing region and the mark has changed.
882 Record the new mark position to allow redisplay optimizations.
883 (display_line): If it->region_beg_charpos is non-zero, set the
884 window's region_showing member to -1. (Bug#13623) (Bug#13626)
885
886 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
887 not bitfield of 1 bit.
888
889 2013-02-03 Daniel Colascione <dancol@dancol.org>
890
891 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
892 daemon mode works on cygw32 when Emacs is installed and not just
893 during development.
894
895 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
896
897 Avoid file time stamp bug on MS-Windows (Bug#13149).
898 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
899 as FAT32 doesn't update time stamps when truncating them.
900 Also, check that a file time stamp is not a multiple of 100 ns;
901 this should catch all instances of the problem on MS-Windows,
902 as its native file system resolution is 100 ns or worse, and
903 checking for a non-multiple of 100 ns should impose only a small
904 overhead on systems with ns resolution.
905
906 2013-02-02 Eli Zaretskii <eliz@gnu.org>
907
908 Avoid encoding file names on MS-Windows when they need to be run
909 through dostounix_filename.
910 * w32.c (normalize_filename): Accept an additional argument
911 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
912 downcase it even if w32-downcase-file-names is non-nil.
913 (dostounix_filename): Accept an additional argument MULTIBYTE and
914 pass it to normalize_filename.
915 (emacs_root_dir): Adjust.
916
917 * msdos.h (dostounix_filename): Adjust prototype.
918
919 * w32.h (dostounix_filename): Adjust prototype.
920
921 * msdos.c (dostounix_filename): Accept an additional argument and
922 ignore it.
923 (init_environment): Adjust callers of dostounix_filename.
924
925 * fileio.c (Ffile_name_directory, file_name_as_directory)
926 (directory_file_name, Fexpand_file_name)
927 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
928 dostounix_filename.
929 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
930 non-nil.
931 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
932 variables, as egetenv is case-insensitive for DOS_NT.
933
934 * dired.c (file_name_completion): Don't call Fdirectory_file_name
935 with an encoded file name.
936
937 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
938 Adjust calls to dostounix_filename.
939
940 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
941
942 * unexw32.c (unexec): Adjust call to dostounix_filename.
943
944 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
945
946 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
947 dostounix_filename.
948
949 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
950 dostounix_filename.
951
952 * callproc.c (Fcall_process): Make sure program name in PATH and
953 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
954 is passed to exec/spawnve, which fails unless the file-name
955 encoding is UTF-8.
956
957 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
958 even if w32-quote-process-args is nil.
959
960 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
961
962 Fix timestamp bug when write-region appends nothing (Bug#13149).
963 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
964 the file's time stamp doesn't change if Emacs happens to write nothing
965 to the file, and on a buggy file system this could cause Emacs to
966 incorrectly infer that the file system doesn't have the bug.
967 Avoid this problem by inhibiting the inference in this case.
968
969 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
970
971 * window.h (struct window): Convert base_line_number, base_line_pos
972 and column_number_displayed members from Lisp_Object to ptrdiff_t.
973 Convert region_showing member from Lisp_Object to bitfield.
974 Remove sequence_number member. Adjust comments.
975 * window.c (sequence_number): Remove.
976 (make_window): Initialize column_number_displayed.
977 * print.c (print_object): Follow the printed representation of
978 frames and print window pointer to distinguish between windows.
979 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
980 * xdisp.c (wset_base_line_number, wset_base_line_pos)
981 (wset_column_number_displayed, wset_region_showing): Remove.
982 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
983 (try_scrolling, try_cursor_movement, redisplay_window)
984 (try_window_reusing_current_matrix, try_window_id, display_line)
985 (display_mode_lines, decode_mode_spec): Adjust users.
986 * .gdbinit (pwinx): Do not print sequence_number.
987
988 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
989
990 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
991 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
992 * dired.c: Include <fcntl.h>.
993 (open_directory): New function, which uses open and fdopendir
994 rather than opendir. DOS_NT platforms still use opendir, though.
995 (directory_files_internal, file_name_completion): Use it.
996 (file_attributes): New function, with most of the old Ffile_attributes.
997 (directory_files_internal, Ffile_attributes): Use it.
998 (file_attributes, file_name_completion_stat): First arg is now fd,
999 not dir name. All uses changed. Use fstatat rather than lstat +
1000 stat.
1001 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1002 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1003 (emacs_readlinkat): New function, with much of the old
1004 Ffile_symlink_p, but with an fd argument for speed.
1005 It uses readlinkat rather than careadlinkatcwd, so that it
1006 need not assume the working directory.
1007 (Ffile_symlink_p): Use it.
1008 * filelock.c (current_lock_owner): Use emacs_readlinkat
1009 rather than emacs_readlink.
1010 * lisp.h (emacs_readlinkat): New decl.
1011 (READLINK_BUFSIZE, emacs_readlink): Remove.
1012 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1013 (emacs_norealloc_allocator, emacs_readlink): Remove.
1014 This stuff is moved to fileio.c.
1015 * w32.c (fstatat, readlinkat): New functions.
1016 (careadlinkat): Don't check that fd == AT_FDCWD.
1017 (careadlinkatcwd): Remove; no longer needed.
1018
1019 2013-01-31 Glenn Morris <rgm@gnu.org>
1020
1021 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1022 (Fwrite_region): Update for new choose_write_coding_system args.
1023 Move the last piece of choose_write_coding_system here. (Bug#13522)
1024 (syms_of_fileio): Add choose-write-coding-system.
1025
1026 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1027
1028 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1029 (sys_close): Zero out the flags for the file descriptor before
1030 closing it. (Bug#13546)
1031
1032 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1033 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1034 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1035 DBCS. (Bug#13553)
1036
1037 * w32.c (w32_get_long_filename, init_environment, readlink):
1038 Support file names encoded in DBCS codepages.
1039 (readlink): Use the current file-name-coding-system, not the ANSI
1040 codepage, to decode and handle targets of symlinks.
1041
1042 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1043
1044 * w32.c (opendir): Now accepts a 'const char *'.
1045
1046 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1047
1048 Remove obsolete redisplay code. See the discussion at
1049 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1050 * dispnew.c (preemption_period, preemption_next_check): Remove.
1051 (Vredisplay_preemption_period): Likewise.
1052 (update_frame, update_single_window, update_window, update_frame_1):
1053 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1054 used, following the 2012-06-22 change.
1055
1056 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1057
1058 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1059
1060 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1061
1062 * font.c (num_fonts): Remove the leftover from old
1063 debugging code. Adjust comment style here and there.
1064 * insdel.c (insert_1): Remove.
1065 * lisp.h (insert_1): Remove prototype.
1066 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1067
1068 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1069
1070 * w32.c (max_filename_mbslen): New function.
1071 (normalize_filename, readdir): Use it to detect locales where ANSI
1072 encoding of file names uses a double-byte character set (DBCS).
1073 If a DBCS encoding is used, advance by characters using
1074 CharNextExA, instead of incrementing a 'char *' pointer.
1075 Use _mbslwr instead of _strlwr. (Bug#13515)
1076
1077 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1078 request of memory reservation to 1.7GB. (Bug#13065)
1079
1080 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1081
1082 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1083 at check_extra_latin label. (Bug#13505)
1084
1085 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1086
1087 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1088 Avoid redundant calls to strlen.
1089
1090 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1091
1092 Drop async_visible and async_iconified fields of struct frame.
1093 This is possible because async input is gone; for details, see
1094 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1095 * frame.h (struct frame): Remove async_visible and async_iconified
1096 members, convert garbaged to unsigned bitfield. Adjust comments.
1097 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1098 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1099 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1100 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1101 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1102 * w32term.c: Ditto.
1103 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1104 properly. Likewise for obscured.
1105 * xterm.c: Ditto.
1106 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1107 properly.
1108 * nsterm.m: Ditto.
1109 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1110
1111 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1112
1113 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1114 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1115
1116 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1117
1118 * xdisp.c (message2, message2_nolog): Remove functions.
1119 (message3, message3_nolog): Extract nbytes and multibyteness directly
1120 from the string. Change all callers.
1121 (message3_nolog): Don't set message_enable_multibyte since set_message
1122 will reset it anyway.
1123 (message1, message1_nolog): Use message3.
1124 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1125 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1126 (set_message): Drop all but the second arg, which has to be a string.
1127 (set_message_1): Simplify now that we know that a1 is NULL and the
1128 second arg is a string.
1129 * frame.h (struct frame): Remove `message_buf' field.
1130 Use glyphs_initialized_p instead.
1131 (FRAME_MESSAGE_BUF): Remove macro.
1132 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1133 * lisp.h (message2, message2_nolog): Remove declarations.
1134 (message3, message3_nolog): Update declarations.
1135 * keyboard.c (read_char_minibuf_menu_text)
1136 (read_char_minibuf_menu_width): Remove vars.
1137 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1138 to correctly handle multibyte strings.
1139 * frame.c (delete_frame): Don't free message_buf any more.
1140 * editfns.c (message_text, message_length): Remove vars.
1141 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1142 * fileio.c (auto_save_error): Use message3 instead of message2.
1143 * dispnew.c (adjust_frame_message_buffer): Remove function.
1144
1145 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1146
1147 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1148 real estate used for the tool bar and the menu bar.
1149
1150 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1151
1152 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1153 hidden buffer is prepared to modification (Bug#13164).
1154
1155 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1156
1157 * window.h (struct window): Change window_end_valid member from
1158 Lisp_Object to a bitfield. Adjust comments.
1159 (wset_window_end_valid): Remove.
1160 * window.c (adjust_window_count): Clear window_end_valid.
1161 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1162 (Fwindow_line_height, set_window_buffer, Frecenter)
1163 (Fsplit_window_internal, Fdelete_other_windows_internal)
1164 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1165 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1166 * xdisp.c (check_window_end, reconsider_clip_changes)
1167 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1168 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1169 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1170
1171 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1172
1173 * xdisp.c (mark_window_display_accurate): Simplify the loop
1174 assuming that the only one of vchild, hchild or buffer window
1175 slots is non-nil. Call mark_window_display_accurate_1 for
1176 the leaf windows only.
1177 (mark_window_display_accurate_1): Always assume leaf window.
1178 Adjust comment.
1179
1180 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1181
1182 * emacs.c (Qkill_emacs_hook): Now static.
1183
1184 * fileio.c (Finsert_file_contents): Simplify.
1185 Remove unnecessary assignments and tests.
1186
1187 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1188
1189 * w32.c (acl_set_file): Don't test for errors unless
1190 set_file_security returns FALSE. Avoids spurious errors when
1191 saving files.
1192
1193 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1194
1195 * fileio.c (Finsert_file_contents): Revert code introduced at
1196 2013-01-18 in favor of the simpler and generally better fix.
1197 Save stack space by removing 'buffer' and reusing 'read_buf'
1198 where appropriate.
1199
1200 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1201
1202 * lisp.h (eabs): Define unconditionally (Bug#13419).
1203 The old "#if !defined (eabs)" was an unnecessary revenant of back
1204 when this macro was called "abs". Document 'eabs' better.
1205
1206 2013-01-19 Glenn Morris <rgm@gnu.org>
1207
1208 * fns.c (Frandom): Doc fix.
1209
1210 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1211
1212 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1213 segfault when there are lots of overlays.
1214
1215 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1216 when there are lots of overlays.
1217 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1218 for the details and a way to reproduce.
1219
1220 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1221
1222 * fileio.c: Use O_APPEND to append.
1223 This corresponds better to the natural interpretation of "append",
1224 and avoids the need to open the output file twice, or to invoke
1225 lseek when APPEND is neither nil nor a number.
1226 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1227 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1228 file possibly twice, and lseeking to its end; this avoids the
1229 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1230 at the same time: the combination is never needed and apparently
1231 it doesn't work with DOS_NT.
1232
1233 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1234 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1235
1236 Allow floating-point file offsets.
1237 Problem reported by Vitalie Spinu in
1238 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1239 * fileio.c (emacs_lseek): Remove.
1240 (file_offset): New function.
1241 (Finsert_file_contents, Fwrite_region): Use it.
1242
1243 2013-01-19 Chong Yidong <cyd@gnu.org>
1244
1245 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1246 aborting on Fsignal (Bug#13289).
1247
1248 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1249
1250 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1251 set_file_security as failure due to insufficient privileges.
1252 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1253 (fstat): Return owner and group like 'stat' and 'lstat' do.
1254
1255 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1256
1257 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1258 The bug was observed on Ubuntu operating inside a virtual machine,
1259 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1260 The workaround introduces a race condition on non-buggy hosts,
1261 but it's an unlikely race and anyway there's a nearly identical
1262 nearby race that can't be fixed.
1263 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1264 New static vars.
1265 (Fwrite_region): Test for file system time stamp bug.
1266 (init_fileio): New function.
1267 * lisp.h (init_fileio): Declare it.
1268 * emacs.c (main): Call it.
1269
1270 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1271 and make it more consistent with other stat-failure diagnostics.
1272
1273 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1274
1275 Fix crash when inserting data from non-regular files.

1283 properly. Do not signal an I/O error too early and so do not leave
1284 not yet decoded characters in a buffer, which was the reason of
1285 redisplay crash. Use list2 to build return value. Adjust comments.

1685 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1686 don't assume the input strings will always be multibyte. If the
1687 input strings are multibyte, decode strings obtained from C
1688 library functions.
1689
1690 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1691
1692 * lisp.h (toplevel): Add two notices to the comment about
1693 defining a new Lisp data type.
1694 * print.c (print_object): If Lisp_Save_Value object's pointer
1695 is the address of a memory area containing Lisp_Objects, try
1696 to print them.
1697 * alloc.c (valid_lisp_object_p): Adjust comment.
1698
1699 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1700
1701 * keyboard.c (record_asynch_buffer_change): Initialize an event
1702 only if it's really needed.
1703 * frame.h (enum output_method): Remove output_mac member since
1704 it's a leftover from the deleted code.
1705 * frame.c (Fframep): Adjust user here ...
1706 * terminal.c (Fterminal_live_p): ... and here.
1707 * coding.c (Qmac): Now here because it's only used to denote
1708 end-of-line encoding type.
1709 (syms_of_coding): DEFSYM it.
1710 * frame.h (Qmac): Remove duplicated declaration.
1711
1712 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1713
1714 * window.c (select_window_1): Now static, since it's used only here.
1715
1716 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1717
1718 * window.c (window_body_cols): Subtract display margins from the
1719 window body width on TTYs as well. See
1720 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1721 for the original report.
1722
1723 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1724
1725 * xdisp.c (redisplay_window): Remove inner local variable
1726 because the outer shadowed one has the same meaning.
1727 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1728 set but never used.
1729 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1730 (xg_create_tool_bar): Adjust users.
1731
1732 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1733
1734 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1735 * buffer.c (Fget_buffer_create): Use it to set compact field of
1736 struct buffer_text to avoid accessing an uninitialized value
1737 when compact_buffer is called for the first time.
1738 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1739 (Fset_buffer_modified_p): Use buffer_window_count to check
1740 whether the buffer is displayed in some window.
1741 * xdisp.c (message_dolog): Likewise.
1742
1743 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1744
1745 * w32.c (acl_set_file): If setting the file security descriptor
1746 fails, and the new DACL is identical to the existing one, silently
1747 return success. This fixes problems for users backing up their
1748 own files without having the necessary privileges for setting
1749 security descriptors.
1750
1751 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1752 values.
1753 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1754 after WaitForSingleObject returns normally. This expedites reader
1755 thread shutdown when delete_child triggers it.
1756 (reap_subprocess): More accurate commentary for why we call
1757 delete_child only when cp->fd is negative.
1758
1759 * w32.c (sys_close): Do not call delete_child on a subprocess
1760 whose handle is not yet closed. Instead, set its file descriptor
1761 to a negative value, so that reap_subprocess will call
1762 delete_child on that subprocess when its SIGCHLD arrives.
1763 This avoids closing handles used for communications between sys_select
1764 and reader_thread, which doesn't give sys_select a chance to
1765 notice that the process exited and invoke the SIGCHLD handler for
1766 it.
1767
1768 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1769
1770 * nsfns.m (Fns_do_applescript): Run event loop until script has
1771 been executed (Bug#12969).
1772 (ns_run_ascript): Chech as_script for nil, set to nil after
1773 executing script.
1774
1775 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1776
1777 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1778
1779 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1780
1781 * w32term.c (w32fullscreen_hook): New function.
1782 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1783
1784 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1785
1786 * fileio.c (Finsert_file_contents): Doc fix.
1787
1788 * w32proc.c (new_child, delete_child, find_child_pid): For a
1789 subprocess, consider its slot being in use as long as its process
1790 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1791 slot when a new process is started immediately after killing
1792 another one, without waiting enough time for the first process to
1793 be reaped and resources allocated for it be orderly freed.
1794 (Bug#13086)
1795 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1796
1797 2012-12-21 Chong Yidong <cyd@gnu.org>
1798
1799 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1800
1801 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1802
1803 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1804
1805 * w32.c (get_name_and_id): Always pass NULL as the first argument
1806 of lookup_account_sid. Avoids crashes with UNC file names that
1807 refer to DFS domains, not to specific machine names. (Bug#12621)
1808 Remove now unused argument FNAME; all callers changed.
1809 (get_file_owner_and_group): Remove now unused argument FNAME; all
1810 callers changed.
1811
1812 2012-12-21 Chong Yidong <cyd@gnu.org>
1813
1814 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1815 error for invalid chars, don't check for a nil return value.
1816
1817 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1818
1819 Avoid calls to CHAR_TO_BYTE if byte position is known.
1820 * editfns.c (make_buffer_string_both): Use move_gap_both.
1821 (Fbuffer_string): Use make_buffer_string_both.
1822 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1823 Adjust comment.
1824 (buf_bytepos_to_charpos): Likewise.
1825 (charpos_to_bytepos): Remove.
1826 * fileio.c (Finsert_file_contents): Use move_gap_both.
1827 * search.c (Freplace_match): Likewise.
1828 * process.c (process_send_region): Likewise. Use convenient
1829 names for byte positions.
1830 * lisp.h (charpos_to_bytepos): Remove prototype.
1831 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1832 * insdel.c (move_gap): Likewise.
1833
1834 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1835
1836 * xdisp.c (redisplay_internal): Remove now-unused local.
1837
1838 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1839
1840 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1841 (redisplay_internal): Don't bother selecting the frame to get the
1842 proper value of frame-local variables (bug#13225).
1843
1844 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1845
1846 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1847 Rename 4th argument since it may be buffer or string. Adjust comment.
1848 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1849
1850 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1851
1852 * coding.c (Fdetect_coding_region): Do not check start and end with
1853 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1854 (code_convert_region): Likewise.
1855
1856 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1857
1858 * w32.c (acl_get_file, acl_set_file): Run the file name through
1859 map_w32_filename, and resolve any symlinks in the file name, like
1860 Posix platforms do.
1861 (acl_set_file): Call revert_to_self, if any privileges were
1862 enabled.
1863
1864 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1865
1866 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1867 ($(BLD)/w32.$(O)): Update dependencies.
1868
1869 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1870
1871 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1872 propagate redisplay's scrolling (if any) to the right window.
1873 (redisplay_internal): Use ensure_selected_frame.
1874 (display_mode_lines): Complete last fix.
1875 * window.c (select_window_1): New func, extracted from select_window.
1876 (select_window): Use it.
1877 * window.h (select_window_1): Declare.
1878
1879 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1880
1881 Emulate Posix ACL APIs on MS-Windows.
1882 * w32.c: Include sddl.h and sys/acl.h.
1883 (SDDL_REVISION_1): Define if not already defined.
1884 (g_b_init_get_security_descriptor_dacl)
1885 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1886 (g_b_init_is_valid_security_descriptor)
1887 (g_b_init_set_file_security): New static flags.
1888 (globals_of_w32): Initialize them to zero.
1889 (SetFileSecurity_Name): New string constant.
1890 (SetFileSecurity_Proc, GetSecurityDescriptorDacl_Proc)
1891 (ConvertStringSecurityDescriptorToSecurityDescriptor_Proc)
1892 (ConvertSecurityDescriptorToStringSecurityDescriptor_Proc)
1893 (IsValidSecurityDescriptor_Proc): New typedefs.
1894 (get_file_security, get_security_descriptor_owner)
1895 (get_security_descriptor_group): Set errno to ENOTSUP.
1896 (set_file_security, get_security_descriptor_dacl)
1897 (is_valid_security_descriptor, convert_sd_to_sddl)
1898 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
1899 (acl_free, acl_get_file, acl_set_file): New functions.
1900
1901 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1902
1903 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1904
1905 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1906 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1907 for some of that bug's symptoms can now cause Emacs to abort.
1908 Remove the workaround.
1909 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1910 The bug that caused SIGCHLD to get lost has been fixed, and the
1911 workaround for it can now cause Emacs to abort.
1912
1913 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1914
1915 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1916 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1917 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1918
1919 2012-12-16 Romain Francoise <romain@orebokech.com>
1920
1921 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1922 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1923 and copy ACL entries of file in addition to SELinux context if set.
1924 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1925
1926 * Makefile.in (LIBACL_LIBS): New macro.

1928
1929 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
1930
1931 * fileio.c (internal_delete_file): Use bool for boolean.
1932
1933 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1934
1935 Fix bug #13079 on MS-Windows with temp files not being deleted.
1936 * w32.h (_child_process): New members input_file and
1937 pending_deletion.

1939 (record_infile, record_pending_deletion): New prototypes.
1940
1941 * w32proc.c (new_child): Initialize input_file and
1942 pending_deletion members of the child.
1943 (delete_child): Delete the child's temporary input file, if any,
1944 that is pending deletion.

1946 (record_infile, record_pending_deletion): New functions.
1947 (reap_subprocess): Fix a typo in DebPrint string.
1948 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1949
1950 * fileio.c (internal_delete_file): Return an int again: non-zero
1951 if delete-file succeeds, zero otherwise.
1952
1953 * lisp.h (internal_delete_file): Adjust prototype.
1954
1955 * callproc.c (Fcall_process): Don't overwrite infile with result
1956 of DECODE_FILE.
1957 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1958 asynchronous subprocess, record the name of the input file name,
1959 if any.
1960 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1961 delete the file, record it as pending deletion when the subprocess
1962 exits.
1963
1964 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1965
1966 * editfns.c [HAVE_PWD_H]: Include grp.h.
1967
1968 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1969
1970 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1971
1972 Fix permissions bugs with setgid directories etc. (Bug#13125)
1973 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1974 to mark it as a placeholder. The old value was often wrong.
1975 The only user of this attribute has been changed to use
1976 file-ownership-preserved-p instead, with its new group arg.
1977 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1978
1979 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
1980
1981 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
1982 Keep selected_window and selected_frame in sync.
1983
1984 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1985
1986 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1987 try to get accurate owner and group information from NT file
1988 security APIs. This is to make most callers of 'stat' and
1989 'lstat', which don't need that information, much faster.
1990
1991 * dired.c (Ffile_attributes) [WINDOWSNT]:
1992 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1993 owner and group information from 'lstat'.
1994
1995 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1996
1997 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1998 as that confuses set-auto-coding, so insist on the head-read
1999 returning the full 1024 bytes. Let lseek compute the tail offset;
2000 less work for us. Do not ignore I/O errors when reading the tail.
2001
2002 * xdisp.c: Minor style fixes.
2003 (init_iterator): Hoist assignment out of if-expression.
2004 (markpos_of_region): Callers now test for sign, not for -1.
2005
2006 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2007
2008 Minor redisplay optimization when the region length is zero.
2009 * xdisp.c (markpos_of_region): New function.
2010 (init_iterator): Do not highlight the region of zero length.
2011 (redisplay_window): Check whether the region is of non-zero length.
2012 (try_cursor_movement): Allow if the region length is zero.
2013 (try_window_reusing_current_matrix, try_window_id): Likewise.
2014
2015 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2016
2017 * search.c (search_buffer): Check the inverse translations of each
2018 character in pattern when the buffer being searched is unibyte.
2019 (Bug#13084)
2020
2021 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2022
2023 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2024 files, fixing a regression from 24.2.
2025 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2026
2027 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2028
2029 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2030 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2031 Remove unnecessary S_ISLNK test, as (contra the comments) this
2032 function can't copy symlinks. Improve quality of error message
2033 when attempting to copy files that are neither regular files nor
2034 directories.
2035
2036 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2037
2038 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
2039 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
2040 * window.c (Frecenter):
2041 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2042 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2043
2044 2012-12-12 Daniel Colascione <dancol@dancol.org>
2045
2046 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2047 the dumped Emacs is not a sparse file, greatly improving Cygwin
2048 "make bootstrap" performance.
2049
2050 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2051
2052 * inotify.c (inotify_callback): Generate an Emacs event for every
2053 incoming inotify event.
2054
2055 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2056
2057 * xdisp.c (handle_face_prop): Fix logic of computing
2058 it->start_of_box_run_p.
2059 (append_space_for_newline): If the glyph row is R2L, reset the
2060 iterator's end_of_box_run_p flag before prepending the space glyph.
2061 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2062 iterator's start_of_box_run_p flag before prepending the stretch.
2063 (append_glyph, produce_image_glyph, append_composite_glyph)
2064 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2065 left_box_line_p and right_box_line_p flags of the glyph for R2L
2066 glyph rows. (Bug#13011)
2067
2068 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2069
2070 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2071 if changed buffer is not shown in a window.
2072 * insdel.c (prepare_to_modify_buffer): Likewise.
2073 * window.c (replace_buffer_in_windows_safely): Do nothing
2074 if buffer is not shown in a window.
2075 (Fforce_window_update): Likewise if string or buffer argument
2076 is passed.
2077
2078 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2079
2080 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2081 encoded_file_name, which is what it is.
2082
2083 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2084
2085 Consistently use marker_position and marker_byte_position.
2086 * fringe.c (Ffringe_bitmaps_at_pos):
2087 * indent.c (Fvertical_motion):
2088 * insdel.c (prepare_to_modify_buffer):
2089 * keyboard.c (make_lispy_position):
2090 * window.c (Fwindow_end, Fpos_visible_in_window_p, unshow_buffer)
2091 (window_scroll_pixel_based, displayed_window_lines)
2092 (Fset_window_configuration):
2093 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
2094 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
2095 Replace direct access to marker fields with calls
2096 to marker_position and/or marker_byte_position.
2097
2098 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
2099
2100 * makefile.w32-in (SIG2STR_H): New macro.
2101 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))

2121 previously weren't calling it in Cygwin builds.
2122
2123 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
2124 Teach the autoconf build system how to compile a Windows resource file

2240
2241 * lread.c (Vload_source_file_function): Doc fix (Bug#11647).

2265 * alloc.c (xputenv): New function.
2266 * dbusbind.c (Fdbus_init_bus):
2267 * emacs.c (main):
2268 * xterm.c (x_term_init):

2274 Save old TZ value on stack, if it's small.
2275 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
2276 instead, use xputenv+unsetenv to set and restore TZ.
2277 (environbuf): Remove static var. All uses removed.
2278 (Fset_time_zone_rule): Do not save TZ and environ;
2279 no longer needed here.
2280 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2281 Move to inside set_time_zone_rule; they don't need file scope any more.
2282 (set_time_zone_rule): Maintain the TZ=value string separately.
2283 (syms_of_editfns): Don't initialize initial_tz;
2284 init_editfns now does it.
2285 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2286 * lisp.h (xputenv): New decl.
2287

2297
2298 * editfns.c (Finsert_char): Make the error message more
2299 informative (Bug#12992).
2300
2301 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2302
2303 Simplify get_lim_data.
2304 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2305 Remove USG and vlimit methods; no longer used these days.
2306 Add #error catchall just in case.
2307
2308 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2309 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2310 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2311 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2312 (deleted_pid_list, Fdelete_process, create_process)
2313 (record_child_status_change, handle_child_signal, deliver_child_signal)
2314 (init_process_emacs, syms_of_process):
2315 Assume SIGCHLD is defined.
2316 (parse_signal): Remove. All uses removed.
2317 (abbr_to_signal): New static function.
2318 (Fsignal_process): Use it to convert signal names to ints.
2319 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2320 kill (getpgrp (), ...).
2321 (emacs_sigaction_init): Assume SIGCHLD is defined.
2322 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2323 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2324 * syssignal.h (EMACS_KILLPG): Remove.
2325 All uses replaced by 'kill' with a negative pid.
2326 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2327 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2328
2329 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2330
2331 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2332 This will cause a production Emacs to dump core instead of
2333 infinite-looping.
2334
2335 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2336
2337 * frame.c (make_frame): Do not set window's buffer to t.
2338 * window.c (Fsplit_window_internal): Likewise. Previously it was
2339 used to indicate that the window is being set up. Now we use
2340 set_window_buffer for all new windows, so the condition in ...
2341 (Fset_window_buffer): ... is always true and can be removed.
2342
2343 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2344
2345 Convenient macro to check whether the buffer is hidden.
2346 * buffer.h (BUFFER_HIDDEN_P): New macro.
2347 * frame.c (make_frame): Use it. Adjust comment.
2348 * buffer.c (candidate_buffer): New function.
2349 (Fother_buffer, other_buffer_safely): Use it.
2350
2351 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2352
2353 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2354 if the child process is still running. Instead, exit the wait
2355 loop and return zero. (Bug#13086)
2356
2357 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2358
2359 * frame.h (x_char_width, x_char_height): Remove prototypes.
2360 * w32term.h (x_char_width, x_char_height): Likewise.
2361 * xfns.c (x_char_width, x_char_height): Remove.

2363 * nsfns.c (x_char_width, x_char_height): Likewise.
2364 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
2365 all window frames.
2366 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
2367 * keyboard.c (command_loop_1): Remove prototype.
2368 (command_loop_2, top_level_1): Add static to match prototype.
2369
2370 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2371
2372 Fix a recently-introduced delete-process race condition.
2373 * callproc.c, process.h (record_kill_process):
2374 New function, containing part of the old call_process_kill.
2375 (call_process_kill): Use it.
2376 This does not change call_process_kill's behavior.
2377 * process.c (Fdelete_process): Use record_kill_process to fix a
2378 race condition that could cause Emacs to lose track of a child.
2379
2380 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2381
2382 Avoid code duplication between prev_frame and next_frame.
2383 * frame.c (candidate_frame): New function. Add comment.
2384 (prev_frame, next_frame): Use it. Adjust comment.
2385
2386 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2387
2388 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2389 fails, signal an error instead of continuing with an empty
2390 string. (Bug#13079)
2391 Encode expanded temp file pattern before passing it to mkstemp or
2392 mktemp.
2393
2394 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2395 Encode the file name before passing it to dostounix_filename, in
2396 case it will downcase it (under w32-downcase-file-names).
2397 (Bug#12933)
2398
2399 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2400
2401 Minor call-process cleanups.
2402 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2403 at the same time as other platforms, to simplify analysis.
2404 No need for fd0_volatile since we have synch_process_fd.
2405 Avoid needless emacs_close; arg is always negative.
2406
2407 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2408
2409 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2410 processes.
2411
2412 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2413
2414 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2415 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2416 and mouse_face_hidden members to a bitfields.
2417 * frame.h (struct frame): Remove set-but-not-used space_width member.
2418 (FRAME_SPACE_WIDTH): Remove.
2419 * nsterm.m, w32term.c, xterm.c: Adjust users.
2420 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2421 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2422 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2423 members to a bitfields.
2424
2425 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2426
2427 Don't let call-process be a zombie factory (Bug#12980).
2428 Fixing this bug required some cleanup of the signal-handling code.
2429 As a side effect, this change also fixes a longstanding rare race
2430 condition whereby Emacs could mistakenly kill unrelated processes,
2431 and it fixes a bug where a second C-g does not kill a recalcitrant
2432 synchronous process in GNU/Linux and similar platforms.
2433 The patch should also fix the last vestiges of Bug#9488,
2434 a bug which has mostly been fixed on the trunk by other changes.
2435 * callproc.c, process.h (synch_process_alive, synch_process_death)
2436 (synch_process_termsig, sync_process_retcode):
2437 Remove. All uses removed, to simplify analysis and so that
2438 less consing is done inside critical sections.
2439 * callproc.c (call_process_exited): Remove. All uses replaced
2440 with !synch_process_pid.
2441 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2442 These take the role of what used to be in unwind-protect arg.
2443 All uses changed.
2444 (block_child_signal, unblock_child_signal):
2445 New functions, to avoid races that could kill innocent-victim processes.
2446 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2447 (call_process_kill): Record killed processes as deleted, so that
2448 zombies do not clutter up the system. Do this inside a critical
2449 section, to avoid a race that would allow the clutter.
2450 (call_process_cleanup): Fix code so that the second C-g works again
2451 on common platforms such as GNU/Linux.
2452 (Fcall_process): Create the child process in a critical section,
2453 to fix a race condition. If creating an asynchronous process,
2454 record it as deleted so that zombies do not clutter up the system.
2455 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2456 light of these changes. Omit unnecessary call to emacs_close
2457 before failure, as the unwind-protect code does that.
2458 * callproc.c (call_process_cleanup):
2459 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2460 * process.c (record_deleted_pid): New function, containing
2461 code refactored out of Fdelete_process.
2462 (Fdelete_process): Use it.
2463 (process_status_retrieved): Remove. All callers changed to use
2464 child_status_change.
2465 (record_child_status_change): Remove, folding its contents into ...
2466 (handle_child_signal): ... this signal handler. Now, this
2467 function is purely a handler for SIGCHLD, and is not called after
2468 a synchronous waitpid returns; the synchronous code is moved to
2469 wait_for_termination. There is no need to worry about reaping
2470 more than one child now.
2471 * sysdep.c (get_child_status, child_status_changed): New functions.
2472 (wait_for_termination): Now takes int * status and bool
2473 interruptible arguments, too. Do not record child status change;
2474 that's now the caller's responsibility. All callers changed.
2475 Reimplement in terms of get_child_status.
2476 (wait_for_termination_1, interruptible_wait_for_termination):
2477 Remove. All callers changed to use wait_for_termination.
2478 * syswait.h: Include <stdbool.h>, for bool.
2479 (record_child_status_change, interruptible_wait_for_termination):
2480 Remove decls.
2481 (record_deleted_pid, child_status_changed): New decls.
2482 (wait_for_termination): Adjust to API changes noted above.
2483
2484 * bytecode.c, lisp.h (Qbytecode): Remove.
2485 No longer needed after 2012-11-20 interactive-p changes.
2486
2487 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2488
2489 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2490 the scroll margin, move point outside the margin. (Bug#13055)
2491
2492 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2493
2494 * gtkutil.c (my_log_handler): New function.
2495 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2496
2497 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2498
2499 * lisp.h (modify_region): Rename to...
2500 (modify_region_1): ...new prototype.
2501 * textprop.c (modify_region): Now static. Adjust users.
2502 * insdel.c (modify_region): Rename to...
2503 (modify_region_1): ...new function to work with current buffer.
2504 Adjust comment and users. Use true and false for booleans.
2505
2506 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2507
2508 * alloc.c (free_save_value): New function.
2509 (safe_alloca_unwind): Use it.
2510 * lisp.h (free_save_value): New prototype.
2511 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2512 Add comment.
2513 (save_excursion_restore): Adjust to match saved data structure.
2514 Use free_save_value to offload some work from GC. Drop obsolete
2515 #if 0 code.
2516
2517 2012-12-03 Chong Yidong <cyd@gnu.org>
2518

2542 * alloc.c (xpalloc): Comment fix.
2543 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2544 and signals an error, do not clear charset_table_size, as
2545 charset_table is still valid.
2546 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2547
2548 Use execve to avoid need to munge environ (Bug#13054).

2589 Do not assume that fd[0], count, filefd, and save_environ survive
2590 vfork. Fix bug whereby wrong errno value could be reported for
2591 pipe failure. Some minor cleanups, too, as follows. Move buf and
2592 bufsize to the context where they're needed. Change new_argv to
2593 be of type char **, as this is more convenient and avoids casts.
2594 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2595 Now local constants, not macros.

2689 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2690 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2691 $(NT_INC)/dirent.h.
2692 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.

2812
2813 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2814
2815 * w32select.c: Include w32common.h before w32term.h, so that
2816 windows.h gets included before w32term.h uses some of its
2817 features, see below.
2818
2819 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2820 New typedefs.

2848 * callproc.c (relocate_fd): Assume F_DUPFD.
2849 * emacs.c, term.c (O_RDWR): Remove.
2850 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2851 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2852 * nsterm.m: Assume <fcntl.h> exists.
2853 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2854 (create_pty, Fmake_network_process, server_accept_connection)
2855 (wait_reading_process_output, init_process_emacs):
2856 Assume O_NONBLOCK.
2857 (wait_reading_process_output): Put in a special case for WINDOWSNT
2858 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2859 It's not clear this is needed, but it's a more-conservative change.
2860 (create_process): Assume FD_CLOEXEC.
2861 (create_process, create_pty): Assume O_NOCTTY.
2862 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2863 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2864 Omit if not DOS_NT, since F_GETFL is not defined there.
2865 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2866 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2867 (O_NOCTTY): Remove.
2868 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2869 lack it, since gnulib guarantees this.

2875 set. Emacs expects that, e.g., in files.el:cd-absolute.
2876
2877 * w32proc.c (create_child): Don't clip the PID of the child
2878 process to fit into an Emacs integer, as this is no longer a
2879 restriction.
2880 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2881 reaping only the process specified by PID argument, if that is
2882 positive. Use PID instead of dead_child to know which process to
2883 reap. Wait for the child to die only if WNOHANG is not in
2884 OPTIONS.
2885 (sys_select): Don't set dead_child.
2886
2887 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,

2892 (record_child_status_change): Remove the setting of
2893 record_at_most_one_child for the !WNOHANG case.
2894
2895 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2896
2897 Fix problems in ns port found by static checking.
2898 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2899 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2900 not to process group.
2901 (ns_select): Use emacs_write, not write, as that's more robust
2902 in the presence of signals.
2903 (fd_handler:): Check for read errors.
2904
2905 2012-11-16 Glenn Morris <rgm@gnu.org>

2912
2913 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2914
2915 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2916 use the same value of thread handle.
2917 (start_timer_thread): If the timer thread exited (due to error),
2918 clean up by closing the two handles it used. Duplicate the caller
2919 thread's handle here, so it gets duplicated only once, when
2920 launching the timer thread. Set priority of the timer thread, not
2921 the caller thread.
2922 (getitimer): Don't duplicate the caller thread's handle here.
2923 (Bug#12832)
2924
2925 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2926
2927 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2928 called (Bug#12834).
2929
2930 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2931
2932 Remove no-longer-used pty_max_bytes variable.
2933 * process.c (pty_max_bytes): Remove; unused.
2934 (send_process): Do not set it.
2935
2936 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2937
2938 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2939 Update dependencies.
2940
2941 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2942
2943 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2944 This follows up on the 2012-09-29 patch that removed indirection
2945 for the 'function' field. Reported by Sergey Vinokurov in
2946 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2947
2948 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2949
2950 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2951 different name, as the MS runtime does not have such a function,
2952 and probably never will.) All callers changed. Ignore DIRFD
2953 value if PATH is an absolute file name, to match Posix spec
2954 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2955 symlinks.
2956
2957 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2958
2959 * xdisp.c (echo_area_display, redisplay_internal):
2960 Omit redundant check whether frame_garbaged is set.
2961
2962 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2963
2964 Use faccessat, not access, when checking file permissions (Bug#12632).
2965 This fixes a bug that has been present in Emacs since its creation.
2966 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2967 which must set some sort of record. (Torek's bug report was against
2968 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2969 same common flaw.) See Torek's Usenet posting
2970 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2971 Posted: Fri Apr 8 14:18:56 1983.
2972 * Makefile.in (LIB_EACCESS): New macro.
2973 (LIBES): Use it.
2974 * callproc.c (init_callproc):
2975 * charset.c (init_charset):
2976 * fileio.c (check_existing, check_executable, check_writable)
2977 (Ffile_readable_p):
2978 * lread.c (openp, load_path_check):
2979 * process.c (allocate_pty):
2980 * xrdb.c (file_p):
2981 Use effective UID when checking permissions, not real UID.
2982 * callproc.c (init_callproc):
2983 * charset.c (init_charset):
2984 * lread.c (load_path_check, init_lread):
2985 Test whether directories are accessible, not merely whether they exist.
2986 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2987 * fileio.c (check_existing, check_executable, check_writable)
2988 (Ffile_readable_p):
2989 Use symbolic names instead of integers for the flags, as they're
2990 portable now.
2991 (check_writable): New arg AMODE. All uses changed.
2992 Set errno on failure.
2993 (Ffile_readable_p): Use faccessat, not stat + open + close.
2994 (Ffile_writable_p): No need to call check_existing + check_writable.
2995 Just call check_writable and then look at errno. This saves a syscall.
2996 dir should never be nil; replace an unnecessary runtime check
2997 with an eassert. When checking the parent directory of a nonexistent
2998 file, check that the directory is searchable as well as writable, as
2999 we can't create files in unsearchable directories.
3000 (file_directory_p): New function, which uses 'stat' on most platforms
3001 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3002 (Ffile_directory_p, Fset_file_times): Use it.
3003 (file_accessible_directory_p): New function, which uses a single
3004 syscall for efficiency.
3005 (Ffile_accessible_directory_p): Use it.
3006 * xrdb.c (file_p): Use file_directory_p.
3007 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3008 * lread.c (openp): When opening a file, use fstat rather than
3009 stat, as that avoids a permissions race. When not opening a file,
3010 use file_directory_p rather than stat.
3011 (dir_warning): First arg is now a usage string, not a format.
3012 Use errno. All uses changed.
3013 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3014 that merely introduced a race.
3015 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3016 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3017 and similarly for the other O_* flags.
3018 * w32.c (sys_faccessat): Rename from sys_access and switch to
3019 faccessat's API. All uses changed.
3020 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3021 (magic_db): Rename from magic_file_p.
3022 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3023 char *, so that we don't have to test for file existence
3024 separately from opening the file for reading. This removes a race
3025 fixes a permission-checking problem, and simplifies the code.
3026 All uses changed.
3027 (file_p): Remove; no longer needed.
3028
3029 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3030
3031 Omit glyphs initialization at startup.
3032 * dispnew.c (glyphs_initialized_initially_p): Remove.
3033 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3034 (Fredraw_frame): Move actual code from here...
3035 (redraw_frame): ...to here. Add eassert. Adjust comment.
3036 (Fredraw_display): Use redraw_frame.
3037 * xdisp.c (clear_garbaged_frames): Likewise.
3038
3039 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3040
3041 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3042 passed to pint2str and pint2hrstr to be at most the size of the
3043 frame's decode_mode_spec_buffer. This avoids crashes with very
3044 large values of FIELD_WIDTH argument to decode_mode_spec.
3045 (Bug#12867)
3046
3047 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3048
3049 Fix a race with verify-visited-file-modtime (Bug#12863).
3050 Since at least 1991 Emacs has ignored an mtime difference of no
3051 more than one second, but my guess is that this was to work around
3052 file system bugs that were fixed long ago. Since the race is
3053 causing problems now, let's remove that code.
3054 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3055 whose time stamp is off by no more than a second. Insist that the
3056 file time stamps match exactly.
3057
3058 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3059
3060 * frame.h (struct frame): Convert external_tool_bar member to
3061 1-bit unsigned bitfield.
3062 * termhooks.h (struct terminal): Remove mouse_moved member since
3063 all users are long dead. Adjust comment on mouse_position_hook.
3064
3065 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3066
3067 Simplify by using FOR_EACH_FRAME here and there.
3068 * frame.c (next_frame, prev_frame, other_visible_frames)
3069 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3070 * w32term.c (x_window_to_scroll_bar): Likewise.
3071 * window.c (window_list): Likewise.
3072 * xdisp.c (x_consider_frame_title): Likewise.
3073 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3074 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3075 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3076 * xmenu.c (menubar_id_to_frame): Likewise.
3077 * xselect.c (frame_for_x_selection): Likewise.
3078 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3079 (x_window_to_menu_bar): Likewise.
3080 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3081
3082 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3083
3084 * data.c (Qdefalias_fset_function): Now static.
3085
3086 Another tweak to vectorlike_header change.
3087 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3088 Remove, and replace all uses with ...
3089 (next_in_free_list, set_next_in_free_list):
3090 New functions, which respect C's aliasing rules better.
3091
3092 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3093
3094 * window.c (list4i): Rename from 'quad'. All uses changed.
3095 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3096
3097 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3098
3099 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3100 warning about mixing declarations and code in ISO C90.
3101
3102 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3103
3104 * window.c (Fsplit_window_internal): Set combination limit of
3105 new parent window to t iff Vwindow_combination_limit is t;
3106 fixing a regression introduced with the change from 2012-09-22.
3107 (Fset_window_combination_limit): Fix doc-string.
3108
3109 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3110
3111 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3112 amount when the scroll margins are too large. When scrolling
3113 backwards in the buffer, give up if cannot reach point or the
3114 scroll margin within a reasonable number of screen lines.
3115 Fixes point position in window under scroll-up/down-aggressively when
3116 point is positioned many lines beyond the window top/bottom.
3117 (Bug#12811)
3118
3119 * ralloc.c (relinquish): If real_morecore fails to return memory
3120 to the system, don't crash; instead, leave the last heap
3121 unchanged and return. (Bug#12774)
3122
3123 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3124
3125 * lisp.h (AUTOLOADP): New macro.
3126 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3127 * data.c (Ffset): Remove special ad-advice-info handling.
3128 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3129 (Fsubr_arity): CSE.
3130 (Finteractive_form): Simplify.
3131 (Fquo): Don't insist on having at least 2 arguments.
3132 (Qdefalias_fset_function): New var.
3133

3140 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3141
3142 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3143
3144 Fix recently introduced crash on MS-Windows (Bug#12839).
3145 * w32term.h (struct scroll_bar): Use convenient header.
3146 (SCROLL_BAR_VEC_SIZE): Remove.
3147 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3148
3149 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3150
3151 Tweak last vectorlike_header change.
3152 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3153 vectorlike object on the free list. This is introduced to avoid
3154 some (but not all) pointer casting and aliasing problems, see
3155 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3156 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3157 objects.
3158 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3159
3160 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3161
3162 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3163 been removed, so remove them here also.
3164
3165 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3166
3167 * doc.c (Fdocumentation): Handle new property
3168 dynamic-docstring-function to replace the old ad-advice-info.
3169
3170 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3171
3172 * fns.c (Qeql, hashtest_eq): Now static.
3173
3174 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3175
3176 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3177 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3178 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3179 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3180
3181 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3182
3183 Use same hash function for hashfn_profiler as for hash_string etc.
3184 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3185 * lisp.h (sxhash_combine): New inline function, with the contents
3186 of the old SXHASH_COMBINE.
3187 * profiler.c (hashfn_profiler): Use it, instead of having a
3188 special hash function containing a comparison that always yields 1.
3189
3190 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3191
3192 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3193 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3194 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3195 Remove unused vars.
3196
3197 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3198
3199 * image.c (xpm_make_color_table_h): Fix compiler error because
3200 make_hash_table changed.
3201
3202 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3203
3204 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3205
3206 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3207
3208 Use ad-hoc comparison function for the profiler's hash-tables.
3209 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3210 (make_log): Use them.
3211 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3212 call Fequal any more.
3213 (Ffunction_equal): New function.
3214 (cmpfn_profiler, hashfn_profiler): New functions.
3215 (syms_of_profiler): Initialize them.
3216 * lisp.h (struct hash_table_test): New struct.
3217 (struct Lisp_Hash_Table): Use it.
3218 * alloc.c (mark_object): Mark hash_table_test fields of hash tables.

3221 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3222 (hash_lookup, hash_remove_from_table): Move assertion checking of
3223 hashfn result here. Check hash-equality before calling cmpfn.
3224 (Fmake_hash_table): Adjust call to make_hash_table.
3225 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3226 (syms_of_fns): Initialize them.
3227 * emacs.c (main): Move syms_of_fns earlier.

3232
3233 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3234
3235 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3236 value of w32-scroll-lock-modifier is neither nil nor one of the
3237 known key modifiers. (Bug#12806)
3238
3239 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3240
3241 Shrink struct vectorlike_header to the only size field.
3242 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3243 Adjust comment.
3244 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3245 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3246 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3247 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3248 information from the vector header. Adjust comment.
3249 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
3250 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
3251 layout.
3252 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
3253 (struct vectorlike_header): Remove next member. Adjust comment.
3254 (struct Lisp_Subr): Add convenient header. Adjust comment.
3255 (allocate_pseudovector): Adjust prototype.
3256 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
3257 (sweep_string, lisp_malloc): Remove useless prototypes.
3258 (enum mem_type): Adjust comment.
3259 (NEXT_IN_FREE_LIST): New macro.
3260 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3261 (Fmake_bool_vector): Likewise.
3262 (struct large_vector): New type to represent allocation unit for
3263 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3264 (large_vectors): Change type to struct large_vector.
3265 (allocate_vector_from_block): Simplify.
3266 (PSEUDOVECTOR_NBYTES): Replace with...
3267 (vector_nbytes): ...new function. Adjust users.
3268 (sweep_vectors): Adjust processing of large vectors.
3269 (allocate_vectorlike): Likewise.
3270 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3271 Add easserts. Adjust XSETPVECTYPESIZE usage.
3272 (allocate_buffer): Use BUFFER_PVEC_INIT.
3273 (live_vector_p): Adjust to match large vector.
3274 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3275 * buffer.h (struct buffer): Add next member.
3276 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3277 New macros.
3278 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3279 * fns.c (internal_equal): Adjust to match enum pvec_type change.

3285
3286 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3287
3288 * keyboard.c (event_to_kboard): Do not dereference
3289 frame_or_window field of SELECTION_REQUEST_EVENT
3290 and SELECTION_CLEAR_EVENT events (Bug#12814).
3291 * xterm.h (struct selection_input_event): Adjust comment.
3292
3293 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3294
3295 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3296 such as Scroll Lock, if the respective keys are treated as
3297 function keys, not as modifiers. This avoids destroying non-ASCII
3298 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3299
3300 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3301
3302 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3303
3304 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3305
3306 Restore some duplicate definitions (Bug#12814).
3307 This undoes part of the 2012-11-03 changes. Some people build
3308 with plain -g rather than with -g3, and they need the duplicate
3309 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3310 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3311 Define as macros, as well as as enums or as constants.
3312
3313 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3314
3315 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3316 to keypad keys (Bug#12816).
3317
3318 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3319
3320 Minor adjustments of recently-changed frame functions.
3321 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3322 known to be a frame (we're in the FRAMEP branch).
3323 * lisp.h (Qframep): Remove decl. frame.h declares this.
3324 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3325 since they're meant for Lisp fixnum values.
3326
3327 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3328
3329 * window.c (Fwindow_combination_limit): Revert to the only
3330 required argument and adjust docstring as suggested in
3331 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html

3334 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3335
3336 Widely used frame validity and checking functions.
3337 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3338 * frame.c (decode_live_frame, decode_any_frame): New functions.
3339 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3340 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3341 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3342 (Fframe_pointer_visible_p): Use decode_any_frame.
3343 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3344 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3345 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3346 (Fframe_focus): Likewise. Allow zero number of arguments.
3347 Adjust docstring.
3348 (frame_buffer_list, frame_buffer_predicate): Remove.
3349 * lisp.h (frame_buffer_predicate): Remove prototype.
3350 * buffer.c (Fother_buffer): Use decode_any_frame.
3351 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3352 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3353 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3354 (Fclose_font, Ffont_info): Use decode_live_frame.
3355 * fontset.c (check_fontset_name): Likewise.
3356 * terminal.c (Fframe_terminal): Likewise.
3357 * w32fns.c (check_x_frame): Likewise.
3358 * window.c (Fminibuffer_window, Fwindow_at)
3359 (Fcurrent_window_configuration): Likewise.
3360 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3361 Likewise. Allow zero number of arguments. Adjust docstring.
3362 * dispnew.c (Fredraw_frame): Likewise.
3363 * xfaces.c (frame_or_selected_frame): Remove.
3364 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)

3368
3369 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3370
3371 * window.c (quad): New function.
3372 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3373 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3374 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3375 (Fwindow_line_height): Use it.
3376 (Fwindow_fringes): Use list3.
3377 (Fwindow_scroll_bars): Use list4.
3378 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3379 (Fwindow_combination_limit): Allow zero number of arguments.
3380
3381 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3382
3383 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3384
3385 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3386 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3387 file descriptor 2 for standard error. (Bug#12805)
3388
3389 2012-11-05 Chong Yidong <cyd@gnu.org>
3390
3391 * process.c (wait_reading_process_output): Revert previous change.
3392
3393 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3394
3395 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3396 This removes code that has been obsolete since around 1990.
3397 * callproc.c (Fcall_process):
3398 * emacs.c (main):
3399 * process.c (create_process):
3400 * term.c (dissociate_if_controlling_tty):
3401 Assume setsid exists.
3402 * callproc.c (child_setup): Assume setpgid exists and behaves as
3403 per POSIX.1-1988 or later.
3404 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3405 * emacs.c (shut_down_emacs):
3406 * sysdep.c (sys_suspend, init_foreground_group):
3407 Assume getpgrp behaves as per POSIX.1-1998 or later.
3408 * msdos.c (setpgrp): Remove.
3409 (tcgetpgrp, setpgid, setsid): New functions.
3410 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3411 * term.c (no_controlling_tty): Remove; unused.
3412 * w32proc.c (setpgrp): Remove.
3413 (setsid, tcgetpgrp): New functions.
3414
3415 Simplify by assuming __fpending.
3416 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3417 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3418 Do not assume that __fpending's result fits in int.
3419
3420 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3421
3422 Remove EMACS_OUTQSIZE+sleep hack.
3423 * dispnew.c (update_frame_1): Remove hack for terminals slower
3424 than 2400 bps, which throttled Emacs by having it sleep.
3425 This code hasn't worked since at least 2007, when the multi-tty stuff
3426 was added, and anyway those old terminals are long dead.
3427 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3428 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3429
3430 Fix data-loss with --version (Bug#9574).
3431 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3432 as we can't assume that emacs_strerror is initialized, and strerror
3433 is good enough here.
3434 (main): Invoke atexit earlier, to catch earlier instances of
3435 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3436
3437 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3438
3439 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3440 (keyDown): Remap keypad keys to X11 virtual key codes.
3441
3442 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3443
3444 Fix data-loss with --batch (Bug#9574).
3445 * emacs.c: Include <close-stream.h>.
3446 (close_output_streams): New function.
3447 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3448 and handles errors appropriately.
3449 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3450 does that now.
3451
3452 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3453 The symptom is a diagnostic "GLib-WARNING **: In call to
3454 g_spawn_sync(), exit status of a child process was requested but
3455 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3456 waitpid(), so exit status can't be returned." The diagnostic
3457 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3458 The real bug is a race condition between Emacs and glib: Emacs
3459 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3460 so that glib can't find it. Work around the bug by invoking
3461 waitpid only on subprocesses that Emacs itself creates.
3462 * process.c (create_process, record_child_status_change):
3463 Don't use special value -1 in pid field, as the caller now must
3464 know the pid rather than having the callee infer it.
3465 The inference was sometimes incorrect anyway, due to another race.
3466 (create_process): Set new 'alive' member if child is created.
3467 (process_status_retrieved): New function.
3468 (record_child_status_change): Use it.
3469 Accept negative 1st argument, which means to wait for the
3470 processes that Emacs already knows about. Move special-case code
3471 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3472 processes that have already been waited for, by testing and
3473 clearing new 'alive' member.
3474 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3475 now does this internally.
3476 (handle_child_signal): Let record_child_status_change do all
3477 the work, since we do not want to reap all exited child processes,
3478 only the child processes that Emacs itself created.
3479 * process.h (Lisp_Process): New boolean member 'alive'.
3480
3481 Omit duplicate definitions no longer needed with gcc -g3.
3482 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3483 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3484 Define only as macros. There's no longer any need to also define
3485 these symbols as enums or as constants, since we now assume
3486 gcc -g3 when debugging.
3487
3488 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3489
3490 * lisp.mk: Adjust comments to the fact that term/internal is now
3491 loaded from loadup.el.
3492
3493 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3494 (msdos_fatal_signal): New function.
3495 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3496 its argument list.
3497
3498 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3499 for GCC versions before 4.
3500 (emacs_raise): Define to call msdos_fatal_signal.
3501
3502 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3503 iterator when starting in the middle of a display or overlay
3504 string. (Bug#12745)
3505
3506 2012-11-03 Chong Yidong <cyd@gnu.org>
3507
3508 * process.c (wait_reading_process_output): Clean up the last
3509 change.
3510
3511 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3512
3513 * process.c (wait_reading_process_output): Avoid a race condition
3514 with SIGIO delivery (Bug#11536).
3515
3516 2012-11-03 Chong Yidong <cyd@gnu.org>
3517
3518 * buffer.c (cursor_type): Untabify docstring.
3519
3520 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3521
3522 * frame.h (struct frame): Drop can_have_scroll_bars member
3523 which is meaningless for a long time. Adjust comments.
3524 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3525 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3526
3527 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3528
3529 * window.c (decode_next_window_args): Update window arg after
3530 calling decode_live_window and so fix crash reported at
3531 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3532 by Juanma Barranquero <lekktu@gmail.com>.
3533 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3534 * font.c (Ffont_at): Likewise.
3535
3536 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3537
3538 * widget.c (resize_cb): New function.
3539 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3540 (EmacsFrameResize): Check if all is up to date before changing frame
3541 size.
3542
3543 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3544
3545 Implement backtrace output for fatal errors on MS-Windows.
3546 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3547 (BACKTRACE_LIMIT_MAX): New macro.
3548 (w32_backtrace): New function.
3549 (emacs_abort): Use w32_backtrace when the user chooses not to
3550 attach a debugger. Update the text of the abort dialog.
3551
3552 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3553
3554 Window-related stuff cleanup here and there.
3555 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3556 Use decode_any_window.
3557 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3558 * xdisp.c (Fformat_mode_line): Likewise.
3559 * font.c (Ffont_at): Use decode_live_window.
3560 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3561 * window.c (decode_next_window_args): Likewise.
3562 (decode_any_window): Remove static.
3563 * window.h (decode_any_window): Add prototype.
3564 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3565 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3566 respectively.
3567
3568 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3569
3570 Remove pad from struct input_event.
3571 * termhooks.h (struct input_event): Remove padding field.
3572 Adjust comment.
3573 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3574 member is never cons for a long time. Adjust comment.
3575 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3576 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3577 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3578 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3579
3580 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3581
3582 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3583
3584 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3585
3586 Fix crash when using Emacs as commit editor for git (Bug#12697).
3587 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3588 and it is configured in conf_post.h.
3589 (Fcall_process): Don't invoke both setsid and setpgid; the former
3590 is enough, if it exists.
3591 * callproc.c (Fcall_process, child_setup):
3592 * process.c (create_process): Use setpgid.
3593 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3594 for the real thing.
3595 * dispnew.c (init_display): Initialize the foreground group
3596 if we are running a tty display.
3597 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3598 * lisp.h (init_foreground_group): New decl.
3599 * sysdep.c (inherited_pgroup): New static var.
3600 (init_foreground_group, tcsetpgrp_without_stopping)
3601 (narrow_foreground_group, widen_foreground_group): New functions.
3602 (init_sys_modes): Narrow foreground group.
3603 (reset_sys_modes): Widen foreground group.
3604
3605 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3606
3607 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3608
3609 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3610
3611 * minibuf.c (read_minibuf): Restore current buffer since
3612 choose_minibuf_frame calling Fset_frame_selected_window may
3613 change it (Bug#12766).
3614
3615 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3616
3617 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3618
3619 2012-10-30 Kenichi Handa <handa@gnu.org>
3620
3621 * font.c (Ffont_at): If WINDOW is specified and it is not
3622 displaying the current buffer, signal an error.
3623
3624 2012-10-29 Daniel Colascione <dancol@dancol.org>
3625
3626 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3627 In preparation for fixing bug#12739, move these functions from
3628 here...
3629
3630 * coding.h, coding.c: ... to here, and compile them only when
3631 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3632 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3633
3634 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3635
3636 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3637 (timer_loop, getitimer, setitimer): Use it instead of
3638 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3639 'clock'.
3640 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3641 literal 10000.
3642
3643 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3644
3645 * nsterm.m (NO_APPDEFINED_DATA): New define.
3646 (last_appdefined_event_data): New variable
3647 (last_appdefined_event): Remove.
3648 (ns_select): Initialize t from last_appdefined_event_data instead
3649 of [last_appdefined_event data1].
3650 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3651 remove last_appdefined_event (Bug#12698).
3652
3653 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3654
3655 * frame.c (x_set_font): Catch internal error.
3656
3657 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3658
3659 Avoid overflow in w32 implementation of interval timers.
3660 When possible, for ITIMER_PROF count only times the main thread
3661 actually executes.
3662 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3663 'volatile ULONGLONG' types. All the other data which was
3664 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3665 (GetThreadTimes_Proc): New typedef.
3666 (w32_get_timer_time): New function, returns a suitable time value
3667 for the timer.
3668 (timer_loop): Enter critical section when accessing ULONGLONG
3669 values of the itimer_data struct, as these accesses are no longer
3670 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3671 Remove unused variable.
3672 (init_timers): Initialize s_pfn_Get_Thread_Times.
3673 (start_timer_thread): Don't assign itimer->caller_thread here.
3674 (getitimer): Assign itimer->caller_thread here.
3675 (setitimer): Always call getitimer to get the value of ticks_now.
3676 (sys_spawnve): Avoid compiler warning about format mismatch.
3677
3678 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3679
3680 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3681 mouse movement events if the menu bar is active. This avoids
3682 producing a busy "hour-glass" cursor by Windows if the mouse
3683 pointer is positioned over a tooltip shown for some menu item.
3684
3685 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3686
3687 Don't assume process IDs fit in int.
3688 * emacs.c (shut_down_emacs) [!DOS_NT]:
3689 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3690 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3691 Use pid_t, not int, to store process IDs, as 'int'
3692 is not wide enough on a few platforms (e.g., AIX and IRIX).
3693
3694 2012-10-23 Kenichi Handa <handa@gnu.org>
3695
3696 The following change is to make face-font-rescale-alist work
3697 correctly for non-ASCII fonts.
3698
3699 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3700 (font_open_for_lface): Handle Vface_font_rescale_alist.
3701
3702 2012-10-23 Chong Yidong <cyd@gnu.org>
3703
3704 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3705
3706 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3707
3708 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3709 for screen font.
3710 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3711
3712 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3713 event (Bug#12681).
3714
3715 2012-10-21 Glenn Morris <rgm@gnu.org>
3716
3717 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3718
3719 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3720
3721 Port to OpenBSD 5.1.
3722 * frame.c (Fmouse_position, Fmouse_pixel_position):
3723 * xdisp.c (produce_stretch_glyph):
3724 Declare local vars only when they're needed.
3725 This is clearer and avoids a warning on OpenBSD about unused vars.
3726 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3727 This is safer, and avoids OpenBSD warnings about unused vars.
3728 * keyboard.c (record_menu_key): Remove unnecessary decl.
3729 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3730 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3731 as our definition clashes with OpenBSD's.
3732 * xfaces.c (load_face_colors, check_lface_attrs)

4149 w32common.
4150
4151 * w32heap.c: Include w32common.h.
4152 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4153 (w32_minor_version, w32_build_number, w32_subtype):
4154 Remove duplicate definitions.
4155
4156 * w32fns.c: Include w32common.h; include w32heap.h only in
4157 WINDOWSNT.
4158
4159 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4160 Use `report_file_error' instead of `error' in order to better
4161 inform users of what went wrong. Increase NTGUI_UNICODE file
4162 dialog box file name length to 32k, the maximum allowed by the NT
4163 kernel.
4164
4165 * w32common.h: New file.
4166 (ROUND_UP, ROUND_DOWN, get_page_size)
4167 (get_allocation_unit, get_processor_type, get_w32_major_version)
4168 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4169 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4170 (OS_NT, os_subtype, cache_system_info): Move here.
4171
4172 * unexw32.c, unexcw.c: Include w32common.h.
4173
4174 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4175 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4176 to call syms_of_w32select.
4177
4178 * cygw32.h: Remove obsolete EXFUN declarations.
4179
4180 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4181
4182 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4183 of w32inevt.o from SOME_MACHINE_OBJECTS.
4184
4185 2012-10-08 Daniel Colascione <dancol@dancol.org>
4186
4187 * image.c: Permanent fix for JPEG compilation issue --- limit
4188 jpeglib `boolean' redefinition to Cygwin builds.
4189
4190 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4191
4192 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4193
4194 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4195 Cygwin.
4196
4197 2012-10-08 Daniel Colascione <dancol@dancol.org>
4198
4199 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4200 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4201 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4202 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4203 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4204 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4205 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4206 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4207 now a supported configuration.
4208
4209 * Makefile.in: consolidate image variables into LIBIMAGE; add
4210 W32_OBJ and W32_LIBS. Compile new files.
4211
4212 * conf_post.h:
4213 (_DebPrint) declare tracing facility for W32 debugging. We need
4214 to unify tracing later.
4215
4216 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4217 unconditional use of W32 Unicode functions. Cygwin runs only on
4218 100% Unicode operating systems.
4219
4220 * cygw32.c: New file. Define Cygwin-specific facilities.
4221 (Fcygwin_convert_path_to_windows)
4222 (Fcygwin_convert_path_from_windows): New user functions for
4223 accessing Cygwin path-munging routines.
4224
4225 * cygw32.h: New file.
4226 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4227 UTF-16LE strings temporarily inside non-Lisp-visible string
4228 objects.
4229
4230 (w32_strerror): Just what it says on the tin.
4231
4232 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4233 also run for Cygwin; both systems have the same problem with using
4234 GUI facilities in a forked child. Also call syms_of_cygw32,
4235 syms_of_w32select in correct places.
4236
4237 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4238 needs fork-then-exec for daemon launching.
4239
4240 * font.h: Include frame.h.
4241
4242 * image.c: Use the image library cache machinery only when we're
4243 compiling for native WINDOWSNT; Cygwin can use shared libraries
4244 like any other Unixlike system.
4245
4246 * keyboard.c: Clarify a comment regarding the input loop.
4247
4248 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4249 functions directly instead of trying to detect at runtime that our
4250 host operating system supports them. We make this change for two
4251 reasons: Cygwin lacks support for the multibyte character
4252 conversion functions used by the legacy menu code, and Cygwin
4253 never needs to rely on non-Unicode APIs.
4254
4255 * unexw32.c (hinst): Declare extern.
4256
4257 * w32.c: Change header order;
4258 (w32_strerror): Move to w32fns.c because we need it for
4259 non-WINDOWSNT builds.
4260
4261 * w32.h: Add #error macro to make sure we don't include w32.h for
4262 Cygwin builds. Remove w32select declarations.
4263
4264 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4265 w32fns.c. w32console.c is WINDOWSNT-only.
4266
4267 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4268 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4269 POSIXy alternative.
4270 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4271 (w32_major_version, w32_minor_version, w32_build_number)
4272 (os_subtype, sound_type): Define here
4273 (w32_defined_color): Make color parameter const for consistency
4274 with other _defined_color functions.
4275 (w32_createwindow): Unconditionally call w32_init_class instead of
4276 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4277 through the code is complex and unnecessary because class
4278 registration is practically free.
4279 (w32_name_of_message): New EMACSDEBUG-only function.
4280 (Fset_message_beep): Move here
4281 (Fx_open_connection): Require that the display name for Windows be
4282 "w32" for consistency, emacsclient disambiguation, and maybe, one
4283 day, multi-window-system support.
4284 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4285 Cygwin files for W32 GUI facilities, since these clearly don't
4286 expect Cygwin names.
4287 (_DebPrint): Define.
4288 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4289 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4290 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4291 (w32_last_error): Remove.
4292
4293 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4294
4295 * w32heap.c (syspage_mask): Declare here.
4296 (cache_system_info): Remove.
4297
4298 * w32inevt.c (faked_key): Define globally, not statically.
4299 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4300 (w32_console_toggle_lock_key): Move to w32fns.c.
4301
4302 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4303
4304 * w32proc.c (_DebPrint): Move to w32fns.c.
4305 * w32select.c: Include string.h, stdio.h for Cygwin.
4306 * w32select.h: New File.
4307
4308 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4309 get_osfhandle.
4310 (w32_message_fd): New variable. Under Cygwin, holds the file
4311 descriptor the system used to tell us about pending thread
4312 messages.
4313
4314 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4315 that prevented compilation under non-WINDOWSNT systems.
4316
4317 (w32_initialize): Open /dev/windows and assign it to
4318 w32_message_fd. Provide w32 feature.
4319
4320 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4321 (WM_EMACS_INPUT_READY): add.
4322 (prepend_msg, w32_message_fd): Declare globally.
4323
4324 * w32xfns.c:
4325 (keyboard_handle): Use only when WINDOWSNT.
4326 (notify_msg_ready): New function. Posts a message to the main
4327 thread's message queue under CYGWIN, which wakes up the main
4328 thread from select(2) by making the /dev/windows file descriptor
4329 ready. Under WINDOWSNT, it sets an event the same way the old
4330 code did.
4331
4332 (post, prepend_msg): Actually call notify_msg_ready instead of
4333 setting the input event directly.
4334
4335 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4336
4337 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4338 but it still has blocs in it, don't return it to the system,
4339 instead of aborting. (Bug#12402)
4340
4341 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4342
4343 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4344
4345 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4346 MAC_OS_X_VERSION_10_6.
4347 (syms_of_nsterm): Remove comment about Panther and above for
4348 ns-antialias-text.
4349 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4350 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4351 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4352
4353 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4354 MAC_OS_X_VERSION_10_4.
4355
4356 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4357 MAC_OS_X_VERSION_10_2.
4358
4359 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4360
4361 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4362 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4363
4364 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4365 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4366 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4367 Remove ns_in_resize check.
4368 (ns_clear_frame_area): Remove resize handle code.
4369
4370 * nsfns.m (ns_in_resize): Remove.
4371 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4372 Remove ns_in_resize check.
4373
4374 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4375
4376 Improve sys_siglist detection.
4377 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4378 defined as a macro, as is done in Solaris.
4379 (sys_siglist_entries): New macro.
4380 (save_strsignal): Use it.
4381 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4382 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4383
4384 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4385
4386 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4387 fullscreen/Fullscreen.
4388
4389 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4390 tobar_height is new.
4391
4392 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4393 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4394 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4395 (windowDidResize:): Check for correct window if old style fullscreen.
4396 Capitalize word in comment. Remove incorrect comment.
4397 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4398 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4399 error in drawing background.
4400 (toggleFullScreen:): Remove comment. Rearrange calls.
4401 Set toolbar values to zero, save old height in tobar_height.
4402 Restore tool bar height when leaving fullscreen.
4403 (canBecomeMainWindow): New function.
4404
4405 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4406
4407 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4408
4409 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4410
4411 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4412
4413 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4414 that time stamps of directories could also be changed.
4415 Don't request the too broad GENERIC_WRITE, only the more restrictive
4416 FILE_WRITE_ATTRIBUTES access rights.
4417
4418 * fileio.c (Fset_file_times): Special-case ignoring errors for
4419 directories only on MSDOS, not on MS-Windows.
4420
4421 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4422
4423 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4424
4425 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4426
4427 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4428 see whether CreateFile failed.
4429
4430 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4431
4432 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4433 to avoid similar races.
4434 * keyboard.c (pending_signals): Now bool, not int.
4435
4436 Port timers to OpenBSD, plus check for timer failures.
4437 OpenBSD problem reported by Han Boetes.
4438 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4439 and/or setitimer.
4440 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4441 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4442 like OpenBSD, which has timer_settime but does not declare it.
4443 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4444 whether to use itimerspec-related primitives. All uses of
4445 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4446
4447 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4448
4449 * profiler.c (handle_profiler_signal): Fix a malloc race
4450 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4451
4452 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4453
4454 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4455
4456 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4457
4458 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4459 consistent with the change in return value of 'safe_strsignal'.
4460
4461 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4462
4463 Prefer plain 'static' to 'static inline' (Bug#12541).
4464 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4465 (bidi_set_sor_type, bidi_push_embedding_level)
4466 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4467 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4468 (bidi_cache_search, bidi_cache_ensure_space)
4469 (bidi_cache_iterator_state, bidi_cache_find)
4470 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4471 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4472 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4473 Now 'static', not 'static inline'.
4474
4475 Count overruns when profiling; change units to ns.
4476 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4477 Give extra weight to samples after overruns, to attempt to count
4478 the time more accurately.
4479 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4480 the underlying primitives nominally do ns.
4481 (Fprofiler_cpu_start): Document the change. Mention that
4482 the sampling intervals are only approximate.
4483
4484 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4485
4486 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4487
4488 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4489 case for the special 0 coding-system.
4490
4491 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4492 (Fmake_overlay): Remove redundant tests.
4493 (fix_start_end_in_overlays): Remove redundant recentering.
4494
4495 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4496
4497 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4498 Update dependencies.
4499
4500 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4501
4502 Fix a malloc race condition involving strsignal.
4503 A signal can arrive in the middle of a malloc, and Emacs's signal
4504 handler can invoke strsignal, which can invoke malloc, which is
4505 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4506 Fix it by altering the signal handler so that it does not invoke
4507 strsignal.
4508 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4509 * process.c (status_message): Use const pointer, in case strsignal
4510 is #defined to safe_strsignal.
4511 * sysdep.c (sys_siglist, init_signals): Always define and
4512 initialize a substitute sys_siglist if the system does not define
4513 one, even if HAVE_STRSIGNAL.
4514 (safe_strsignal): Rename from strsignal. Always define,
4515 using sys_siglist. Return a const pointer.
4516 * syssignal.h (safe_strsignal): New decl.
4517 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4518
4519 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4520
4521 * w32proc.c (timer_loop): Fix code that waits for timer
4522 expiration, to avoid high CPU usage.
4523
4524 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4525
4526 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4527 (sweep_weak_table): Remove redundant prototypes.
4528
4529 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4530
4531 * emacs.c: Move the inclusion of TERM_HEADER after including
4532 windows.h on WINDOWSNT. This avoids compilation problems with
4533 MSVC.
4534
4535 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4536
4537 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4538 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4539 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4540 as the previous version used 'void *'.
4541
4542 * ralloc.c (ROUNDUP): Fix last change.
4543 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4544 'size_t'.
4545
4546 * w32proc.c <disable_itimers>: New static flag.
4547 (init_timers): Initialize it to zero, after creating the critical
4548 sections used by the timer threads.
4549 (term_timers): Set to 1 before deleting the critical sections.
4550 (getitimer, setitimer): If disable_itimers is non-zero, return an
4551 error indication without doing anything. Reported by Fabrice
4552 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4553 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4554 return results.
4555 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4556 support timers.
4557
4558 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4559 term_ntproc after all the other bookkeeping, to get timers working
4560 as long as possible.
4561
4562 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4563
4564 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4565 Suggested by Juri Linkov in
4566 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4567
4568 Prefer plain 'static' to 'static inline' (Bug#12541).
4569 With static functions, modern compilers inline pretty well by
4570 themselves; advice from programmers often hurts as much as it helps.
4571 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4572 this change shrinks the text size of the Emacs executable by 1.1%
4573 without affecting CPU significantly in my benchmark.

4772 Windows-specific code to display the hourglass mouse pointer is no
4773 longer used.
4774 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
4775 to hourglass timer expiration.

4855
4856 Profiler improvements: more-accurate timers, overflow checks.
4857 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4858 signal.h, setjmp.h. Include systime.h instead.
4859 (saturated_add): New function.
4860 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

4866 All uses changed to store the new value.
4867 (handle_profiler_signal): Rename from sigprof_handler_1,
4868 for consistency with other handlers. Do not check whether
4869 cpu_log is a hash-table if garbage collecting, since it
4870 doesn't matter in that case.
4871 (deliver_profiler_signal): Rename from sigprof_handler,
4872 for consistency with other handlers.
4873 (setup_cpu_timer): New function, with much of what used to be in
4874 Fprofiler_cpu_start. Check for out-of-range argument.
4875 Prefer timer_settime if available, and prefer
4876 thread cputime clocks, then process cputime clocks, then
4877 monotonic clocks, to the old realtime clock. Use make_timeval
4878 to round more-correctly when falling back to setitimer.
4879 (Fprofiler_cpu_start): Use it.
4880 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4881 Don't assume that passing NULL as the 2nd argument of setitimer
4882 is the same as passing a pointer to all-zero storage.
4883 Ignore SIGPROF afterwards.
4884 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4885 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4886 non-fatal signal handlers. Ignore SIGPROF on startup.
4887 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4888 in profiler.c, since sysdep.c now uses it.
4889
4890 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4946 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4947 Since this stuff is now private to charset.c, there's no need for

4980
4981 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4982
4983 Prefer POSIX timers if available.
4984 They avoid a race if the timer is too close to the current time.
4985 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4986 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

4988
4989 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4990

4992 CHAR_STRING_ADVANCE.
4993 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4994 STRING_CHAR_ADVANCE.
4995
4996 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4997
4998 Move Vlibrary_cache to emacs.c and reset before dumping.
4999
5000 * lisp.h (reset_image_types): Declare.
5001 [WINDOWSNT] (Vlibrary_cache): Declare.
5002
5003 * image.c (reset_image_types): New function.
5004
5005 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5006 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
5007 (Fdump_emacs): Reset Vlibrary_cache and image_types.
5008
5009 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
5010 (globals_of_w32) <Vlibrary_cache>: Do not initialize.

5013
5014 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5015
5016 * w32proc.c (sys_signal): Handle all signals defined by the
5017 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5018 handlers for signals supported by Windows. Don't override
5019 term_ntproc as the handler for SIGABRT.
5020 (sigaction): Rewrite to call sys_signal instead of duplicating its
5021 code.
5022 (sys_kill): Improve commentary.
5023
5024 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5025 consistency with a signature of a signal handler. All callers
5026 changed.
5027 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5028 install term_ntproc as a signal handler for SIGABRT, as that
5029 should be done by the dumped Emacs.
5030
5031 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5032
5033 * w32select.c (term_w32select): Protect against repeated
5034 invocation by setting clipboard_owner to NULL after calling
5035 DestroyWindow.
5036
5037 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5038 and term_ntproc to their modified signatures.
5039
5040 * character.c (char_string, string_char): Remove calls to
5041 MAYBE_UNIFY_CHAR. See the discussion starting at
5042 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5043 for the details.
5044
5045 2012-09-25 Chong Yidong <cyd@gnu.org>
5046
5047 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5048
5049 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5050
5051 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5052 when encountering an unknown bytecode.
5053
5054 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5055
5056 image.c, indent.c: Use bool for booleans.
5057 * dispextern.h (struct image_type): Members valid_p, load, init
5058 now return bool, not int. All uses changed.
5059 * image.c: Omit unnecessary static decls.
5060 (x_create_bitmap_mask, x_build_heuristic_mask):
5061 Return void, not int, since callers don't care about the return value.

5096 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5097
5098 Move pid_t related decls out of lisp.h.
5099 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5100 (interruptible_wait_for_termination):
5101 Move these decls from lisp.h to syswait.h, since they use pid_t.
5102 Needed on FreeBSD; see Herbert J. Skuhra in
5103 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5104 * callproc.c: Include syswait.h.
5105
5106 gnutls.c, gtkutil.c: Use bool for boolean.
5107 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)

5118 (is_box_type, xg_tool_item_stale_p, xg_update_tool_bar_sizes)
5119 (update_frame_tool_bar, free_frame_tool_bar):
5120 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
5121 * nsmenu.m (ns_update_menubar):
5122 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5123 * xfns.c (Fx_show_tip) [USE_GTK]:
5124 Use bool for boolean.
5125 * gtkutil.c (xg_update_frame_menubar):
5126 * xmenu.c (update_frame_menubar):
5127 Return void, not int, since caller ignores return value.
5128 * gtkutil.c (xg_change_toolbar_position):
5129 Return void, not 1.
5130
5131 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5132
5133 * makefile.w32-in (BLOCKINPUT_H): Remove.
5134 (SYSSIGNAL_H): New macro.
5135 ($(BLD)/alloc.$(O), $(BLD)/atimer.$(O), $(BLD)/buffer.$(O))

5149
5150 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5151
5152 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5153 fatal_error_backtrace.
5154
5155 * w32proc.c (sys_kill): Undo last change: don't do anything when
5156 invoked to deliver SIGABRT to our own process. This is now
5157 handled by emacs_raise.
5158
5159 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5160
5161 * w32term.c (w32_read_socket): Remove leftover reference to
5162 interrupt_input_pending.
5163
5164 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5165
5166 Do not use SA_NODEFER.
5167 Problem reported by Dani Moncayo in
5168 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5169 * alloc.c (die):
5170 * sysdep.c (emacs_abort): Do not reset signal handler.
5171 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5172 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5173 wanted even on POSIXish hosts, and it doesn't work on Windows.
5174
5175 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5176
5177 * xterm.c (x_term_init): Call fixup_locale before and after calling
5178 gtk_init (Bug#12392).
5179
5180 2012-09-23 Chong Yidong <cyd@gnu.org>
5181
5182 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5183 Vdynamic_library_alist.
5184
5185 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5186 (Fgnutls_available_p): Caller changed.
5187
5188 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5189 (Flibxml_parse_xml_region): Likewise.
5190
5191 * dispextern.h (struct image_type): Remove arg from init function.
5192
5193 * image.c (Finit_image_library, lookup_image_type)
5194 (define_image_type): Remove now-unneeded second arg.
5195 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5196 (init_tiff_functions, init_gif_functions, init_svg_functions):
5197 Arglist and w32_delayed_load calling convention changed.
5198 (gs_type): Remove init_gs_functions; there is no such function.
5199 (valid_image_p, make_image): Fix caller to lookup_image_type.
5200
5201 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5202
5203 Simplify and avoid signal-handling races (Bug#12471).
5204 * alloc.c (die):
5205 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5206 Avoid recursive loop if there's a fatal error in the function itself.
5207 * atimer.c (pending_atimers):
5208 * blockinput.h: Don't include "atimer.h"; no longer needed.
5209 (interrupt_input_pending): Remove. All uses removed.
5210 pending_signals now counts both atimers and ordinary interrupts.
5211 This is less racy than having three separate pending-signal flags.
5212 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5213 (input_blocked_p):
5214 Rename from their upper-case counterparts BLOCK_INPUT,
5215 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5216 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5217 This makes it easier to access volatile variables more accurately.
5218 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5219 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5220 that's more reliable if the code is buggy and sets
5221 interrupt_input_blocked to a negative value. All uses changed.
5222 * atimer.c (deliver_alarm_signal):
5223 Remove. No need to deliver this to the parent; any thread can
5224 handle this signal now. All uses replaced by underlying handler.
5225 * atimer.c (turn_on_atimers):
5226 * dispnew.c (handle_window_change_signal):
5227 * emacs.c (handle_danger_signal):
5228 * keyboard.c (kbd_buffer_get_event):
5229 Don't reestablish signal handler; not needed with sigaction.
5230 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5231 (UNBLOCK_INPUT_TO):
5232 Rework to avoid unnecessary accesses to volatile variables.
5233 (UNBLOCK_INPUT_TO): Now a function.
5234 (totally_unblock_input, unblock_input): New decls.
5235 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5236 (init_data): Remove. Necessary stuff now done in init_signal.
5237 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5238 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5239 (fatal_error_code): Remove; no longer needed.
5240 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5241 it doesn't always backtrace. All uses changed. No need to reset
5242 signal to default, since sigaction and/or die does that for us now.
5243 Use emacs_raise (FOO), not kill (getpid (), FOO).
5244 (main): Check more-accurately whether we're dumping.
5245 Move fatal-error setup to sysdep.c
5246 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5247 * gtkutil.c (xg_get_file_name, xg_get_font):
5248 Remove no-longer-needed signal-mask manipulation.
5249 * keyboard.c, process.c (POLL_FOR_INPUT):
5250 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5251 * keyboard.c (read_avail_input): Remove.
5252 All uses replaced by gobble_input.
5253 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5254 (kbd_buffer_store_event_hold, gobble_input):
5255 (record_asynch_buffer_change) [USABLE_SIGIO]:
5256 (store_user_signal_events):
5257 No need to mess with signal mask.
5258 (gobble_input): If blocking input and there are terminals, simply
5259 set pending_signals to 1 and return. All hooks changed to not
5260 worry about whether input is blocked.
5261 (process_pending_signals): Clear pending_signals before processing
5262 them, in case a signal comes in while we're processing.
5263 By convention callers now test pending_signals before calling us.
5264 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5265 New functions, to support changes to blockinput.h.
5266 (handle_input_available_signal): Now extern.
5267 (reinvoke_input_signal): Remove. All uses replaced by
5268 handle_async_input.
5269 (quit_count): Now volatile, since a signal handler uses it.
5270 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5271 All callers changed. Block SIGINT only if not already blocked.
5272 Clear sigmask reliably, even if Fsignal returns, which it can.
5273 Omit unnecessary accesses to volatile var.
5274 (quit_throw_to_read_char): No need to restore sigmask.
5275 * keyboard.c (gobble_input, handle_user_signal):
5276 * process.c (wait_reading_process_output):
5277 Call signal-handling code rather than killing ourselves.
5278 * lisp.h: Include <float.h>, for...
5279 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5280 (pending_signals): Now volatile.
5281 (syms_of_data): Now const if IEEE floating point.
5282 (handle_input_available_signal) [USABLE_SIGIO]:
5283 (terminate_due_to_signal, record_child_status_change): New decls.
5284 * process.c (create_process): Avoid disaster if memory is exhausted
5285 while we're processing a vfork, by tightening the critical section
5286 around the vfork.
5287 (send_process_frame, process_sent_to, handle_pipe_signal)
5288 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5289 ignores SIGPIPE.
5290 (send_process): No need for setjmp/longjmp any more, since the
5291 SIGPIPE stuff is now gone. Instead, report an error if errno
5292 is EPIPE.
5293 (record_child_status_change): Now extern. PID and W are now args.
5294 Return void, not bool. All callers changed.
5295 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5296 Remove. All uses removed. This bug should be fixed now in a
5297 different way.
5298 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5299 and record the child status change directly. This avoids the
5300 need to futz with the signal mask.
5301 (process_fatal_action): Move here from emacs.c.
5302 (emacs_sigaction_flags): New function, containing
5303 much of what used to be in emacs_sigaction_init.
5304 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5305 caught by emacs, to make races less likely.
5306 (deliver_process_signal): Rename from handle_on_main_thread.
5307 All uses changed.
5308 (BACKTRACE_LIMIT_MAX): Now at top level.
5309 (thread_backtrace_buffer, threadback_backtrace_pointers):
5310 New static vars.
5311 (deliver_thread_signal, deliver_fatal_thread_signal):
5312 New functions, for more-accurate delivery of thread-specific signals.
5313 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5314 (deliver_arith_signal): Handle in this thread, not
5315 in the main thread, since it's triggered by this thread.
5316 (maybe_fatal_sig): New function.
5317 (init_signals): New arg DUMPING so that we can be more accurate
5318 about whether we're dumping. Caller changed.
5319 Treat thread-specific signals differently from process-general signals.
5320 Block all signals while handling fatal error; that's safer.
5321 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5322 on IEEE hosts.
5323 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5324 Ignore SIGPIPE unless batch.
5325 (emacs_backtrace): Output backtrace for the appropriate thread,
5326 which is not necessarily the main thread.
5327 * syssignal.h: Include <stdbool.h>.
5328 (emacs_raise): New macro.
5329 * xterm.c (x_connection_signal): Remove; no longer needed
5330 now that we use sigaction.
5331 (x_connection_closed): No need to mess with sigmask now.
5332 (x_initialize): No need to reset SIGPIPE handler here, since
5333 init_signals does this for us now.
5334
5335 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5336
5337 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5338 background rect may be larger (Bug#12245).
5339
5340 2012-09-23 Chong Yidong <cyd@gnu.org>
5341
5342 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5343
5344 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5345
5346 * .gdbinit: Just stop at fatal_error_backtrace.
5347 See Stefan Monnier's request in
5348 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5349 Remove no-longer-used query of system type.
5350
5351 2012-09-22 Chong Yidong <cyd@gnu.org>
5352
5353 * search.c (Freplace_match): Doc fix (Bug#12325).
5354
5355 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5356
5357 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5358 (Fline_end_position): Doc fix.
5359
5360 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5361
5362 2012-09-22 Chong Yidong <cyd@gnu.org>
5363
5364 * dispextern.h (struct image_type): Add new slot, storing a type
5365 initialization function.
5366
5367 * image.c (define_image_type): Call the image initializer function
5368 if it is defined. Arguments and return value changed.
5369 (valid_image_p, make_image): Callers changed.
5370 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5371 (gif_type, imagemagick_type, svg_type, gs_type):
5372 Add initialization functions.
5373 (Finit_image_library): Call lookup_image_type.
5374 (CHECK_LIB_AVAILABLE): Macro deleted.
5375 (lookup_image_type): Call define_image_type here, rather than via
5376 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5377 (syms_of_image): Move define_image_type calls for xbm_type and
5378 pbm_type to lookup_image_type.
5379
5380 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5381
5382 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5383 'idle_timers' from here ...
5384 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5385 lists, to avoid infloops when the timer does something stupid,
5386 like reinvoke itself with the same or smaller time-out.
5387 (Bug#12447)
5388
5389 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5390
5391 * window.c (Fsplit_window_internal): Handle only Qt value of
5392 Vwindow_combination_limit separately.
5393 (Qtemp_buffer_resize): New symbol.
5394 (Vwindow_combination_limit): New default value.
5395 Rewrite doc-string.
5396
5397 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5398
5399 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5400 the new overlay string. (Bug#10159)
5401
5402 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5403
5404 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5405 or that fprintf is async-signal-safe. POSIX doesn't require
5406 either assumption.
5407
5408 2012-09-22 Chong Yidong <cyd@gnu.org>
5409
5410 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5411 (Bug#8207).
5412
5413 2012-09-22 Kenichi Handa <handa@gnu.org>
5414
5415 * composite.c (composition_reseat_it): Handle the case that a
5416 grapheme cluster is not covered by a single font (Bug#12352).
5417
5418 2012-09-21 Chong Yidong <cyd@gnu.org>
5419
5420 * image.c (define_image_type): Avoid adding duplicate types to
5421 image_types (Bug#12463). Suggested by Jörg Walter.
5422
5423 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5424
5425 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5426 (print_load_command_name): Add case LC_DATA_IN_CODE.
5427 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5428
5429 2012-09-21 Glenn Morris <rgm@gnu.org>
5430
5431 * eval.c (Frun_hook_with_args_until_success)
5432 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5433
5434 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5435
5436 * fileio.c (Ffile_selinux_context): Only call freecon when
5437 lgetfilecon succeeded.
5438 (Fset_file_selinux_context): Likewise. (Bug#12444)
5439
5440 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5441
5442 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5443 reordering, locate the cursor by calling set_cursor_from_row; if
5444 that fails, clear the desired glyph matrix before returning a
5445 failure indication to the caller. Fixes leaving garbled display
5446 when fast scrolling with a down-key. (Bug#12403)
5447 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5448 scrolling through multibyte text.
5449
5450 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5451
5452 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5453 calling mark_vectorlike since that's the one that marks the window.
5454 (mark_discard_killed_buffers): Mark the final cdr.
5455 * window.h (struct window): Move prev/next_buffers to the
5456 non-standard fields.
5457 * window.c (make_window): Initialize prev/next_buffers manually.
5458
5459 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5460
5461 Omit unused arg EXPECTED from socket hooks.
5462 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5463 * nsterm.m (ns_term_init):
5464 * termhooks.h (struct terminal.read_socket_hook):
5465 * w32inevt.c (w32_console_read_socket):
5466 * w32term.c (w32_read_socket):
5467 * xterm.c (XTread_socket):
5468 Omit unused arg EXPECTED. All callers changed.
5469 (store_user_signal_events): Return void, not int, since callers no
5470 longer care about the return value. All uses changed.
5471
5472 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5473
5474 * w32gui.h (XParseGeometry): Do not declare.
5475
5476 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5477
5478 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5479 Ignore 'expected'. See Eli Zaretskii in
5480 <http://bugs.gnu.org/12471#8> (last line).
5481
5482 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5483 (XParseGeometry): Now static. Substitute extremal values for
5484 values that are out of range.
5485
5486 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5487
5488 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5489
5490 * nsfns.m (XParseGeometry): Remove.
5491 (Fx_create_frame): Call x_set_offset to correctly interpret
5492 top_pos in geometry.
5493
5494 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5495 (Fx_parse_geometry): If there is a space in string, call
5496 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5497
5498 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5499
5500 * search.c (scan_buffer): Use character positions in calls to
5501 region_cache_forward and region_cache_backward, not byte
5502 positions. (Bug#12196)
5503
5504 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5505 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5506
5507 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5508 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5509 emacs_blocked_malloc, now deleted.
5510
5511 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5512
5513 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5514 The workaround was for improving performance on Solaris 2.4, but
5515 is getting in the way now. Emacs will still work if someone is
5516 still running Solaris 2.4 in a museum somewhere; Sun dropped
5517 support for Solaris 2.4 in 2003.
5518 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5519 * process.c (create_process) [HAVE_WORKING_VFORK]:
5520 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5521 since Emacs no longer uses vfork on that platform.
5522
5523 2012-09-17 Glenn Morris <rgm@gnu.org>
5524
5525 * emacs.c: Use COPYRIGHT.
5526
5527 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5528
5529 Remove configure's --without-sync-input option (Bug#12450).
5530 When auditing signal-handling in preparation for cleaning it up,
5531 I found that SYNC_INPUT has race conditions and would be a real
5532 pain to fix. Since it's an undocumented and deprecated
5533 configure-time option, now seems like a good time to remove it.
5534 Also see <http://bugs.gnu.org/11080#16>.
5535 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5536 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5537 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5538 (malloc_hysteresis):
5539 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5540 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5541 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5542 (dont_register_blocks, bytes_used_when_reconsidered)
5543 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5544 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5545 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5546 Remove. All uses removed.
5547 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5548 implementation, one that depends on whether the new macro
5549 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5550 is defined.
5551 * atimer.c (run_timers, handle_alarm_signal):
5552 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5553 (handle_async_input, process_pending_signals)
5554 (handle_input_available_signal, init_keyboard):
5555 * nsterm.m (ns_read_socket):
5556 * process.c (wait_reading_process_output):
5557 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5558 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5559 (emacs_write):
5560 * xterm.c (XTread_socket):
5561 Assume SYNC_INPUT.
5562 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5563 * eval.c (handling_signal): Remove. All uses removed.
5564 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5565 All uses replaced with the SYNC_INPUT version.
5566 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5567 Remove decls.
5568 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5569 Now static.
5570
5571 * font.c (Ffont_shape_gstring): Remove unused local.
5572
5573 2012-09-16 Glenn Morris <rgm@gnu.org>
5574
5575 * Makefile.in (clean): No longer run nextstep's clean.
5576
5577 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5578 (ns_frag): Remove.
5579 (ns-app): Move here from ns.mk, and simplify.
5580 (clean): Simplify nextstep entry.
5581 * ns.mk: Remove file.
5582
5583 2012-09-17 Kenichi Handa <handa@gnu.org>
5584
5585 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5586 not covert the last few charactes.
5587
5588 2012-09-16 Kenichi Handa <handa@gnu.org>
5589
5590 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5591 here, but just check the validity of glyphs in the glyph-string.
5592
5593 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5594
5595 * window.c (Fwindow_parameter, Fset_window_parameter):
5596 Accept any window as argument (Bug#12452).
5597
5598 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5599
5600 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5601 to ns_term_init to avoid memory leak.
5602
5603 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5604 explicit retain/release.
5605 (ns_term_init): Only allow one display. Initialize outerpool and
5606 ns_*_types.
5607
5608 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5609
5610 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5611 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5612 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5613 the Microsoft problem in a different way, by altering ../nt/config.nt.
5614
5615 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5616
5617 * w32xfns.c:
5618 * w32uniscribe.c:
5619 * w32term.c:
5620 * w32select.c:
5621 * w32reg.c:
5622 * w32proc.c:
5623 * w32menu.c:
5624 * w32inevt.c:
5625 * w32heap.c:
5626 * w32font.c:
5627 * w32fns.c:
5628 * w32console.c:
5629 * w32.c:
5630 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5631 by lisp.h. This completes removal of setjmp.h inclusion
5632 erroneously announced in the previous commit. (Bug#12446)
5633
5634 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5635 more accurate.
5636
5637 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5638 not defined as a macro. The latter happens on MS-Windows.
5639 (Bug#12446)
5640
5641 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5642
5643 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5644 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5645 Some instances of '#include <setjmp.h>' removed, if the
5646 only reason for the instance was because "lisp.h" was included.
5647 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5648 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5649 and _longjmp with the new symbols. Emacs already uses _setjmp if
5650 available, so this change affects only POSIXish hosts that have
5651 sigsetjmp but not _setjmp, such as some versions of Solaris and
5652 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5653 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5654 (png_load_body) [HAVE_PNG]:
5655 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5656 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5657 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5658 since PNG requires jmp_buf. This is the only exception to the
5659 general rule that we now use sys_setjmp and sys_longjmp.
5660 This exception is OK since this code does not change the signal
5661 mask or longjmp out of a signal handler.
5662
5663 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5664
5665 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5666 Include "syssignal.h", for 'main_thread'.
5667
5668 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5669
5670 Avoid out-of-range marker position (Bug#12426).
5671 * insdel.c (replace_range, replace_range_2):
5672 Adjust markers before overlays, as suggested by comments.
5673 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5674 Remove redundant check before calling offset_intervals.
5675
5676 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5677
5678 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5679 current buffer (Bug#12387).
5680
5681 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5682
5683 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5684
5685 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5686
5687 Use a more backwards-compatible timer format (Bug#12430).
5688 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5689 vector element, not from the 4th, since PSECS is now at the end.
5690 (Fcurrent_idle_time): Doc fix.
5691
5692 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5693
5694 Function to mark objects and remove killed buffers at once.
5695 * alloc.c (discard_killed_buffers): Rename to ...
5696 (mark_discard_killed buffers) ... new name. Add marking
5697 of remaining objects. Fix comment. Adjust users.
5698 (mark_object): Do not touch frame buffer lists here.
5699 * frame.c (delete_frame): Reset frame buffer lists here.
5700
5701 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5702
5703 Better workaround for GNOME bug when --enable-gcc-warnings.
5704 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5705 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5706 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5707
5708 Simplify SIGIO usage (Bug#12408).
5709 The code that dealt with SIGIO was crufty and confusing, e.g., it
5710 played tricks like "#undef SIGIO" but these tricks were not used
5711 consistently. Simplify mostly by not #undeffing standard symbols,
5712 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5713 or not as we please) rather than "defined SIGIO" (standard symbol
5714 that we probably shouldn't #undef).
5715 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5716 Modules that need it can include it.
5717 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5718 * dispextern.h (ignore_sigio): New decl.
5719 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5720 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5721 * emacs.c (shut_down_emacs):
5722 * keyboard.c (kbd_buffer_store_event_hold):
5723 Use ignore_sigio rather than invoking 'signal' directly.
5724 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5725 for FIONREAD.
5726 (FIONREAD, SIGIO): Do not #undef.
5727 (tty_read_avail_input): Use #error rather than a syntax error.
5728 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5729 for I_PIPE, used by SETUP_SLAVE_PTY.
5730 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5731 * sysdep.c (croak): Remove; no longer needed. This bit of
5732 temporary code, with Fred N. Fish's comment that it's temporary,
5733 has been in Emacs since at least 1992!
5734 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5735 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5736 * syssignal.h (croak): Remove decl.
5737 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5738 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5739 now that we're termios-only.
5740 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5741 * term.c (dissociate_if_controlling_tty): Use #error rather than
5742 a run-time error.
5743
5744 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5745 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5746 to work around GNOME bug 683906.
5747 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5748 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5749 This works around GCC bug 54561.
5750
5751 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5752
5753 More fixes for 'volatile' and setjmp/longjmp.
5754 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5755 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5756 (png_load_body) [HAVE_PNG]:
5757 (jpeg_load_body) [HAVE_JPEG]:
5758 New function, with most of the old parent function's body.
5759 (png_load) [HAVE_PNG]:
5760 (jpeg_load) [HAVE_JPEG]:
5761 Invoke the new function, to avoid longjmp munging our locals.
5762 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5763 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5764 longjmp is passed 2, as the C standard doesn't guarantee this.
5765 Instead, store the failure code into mgr->failure_code.

5767 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5768
5769 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5770 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5771 (syms_of_keyboard): Remove support for unread-command-char.
5772
5773 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5774
5775 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5776 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5777 violation. (Bug#12426)
5778
5779 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5780
5781 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5782
5783 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5784
5785 * eval.c: Add `inhibit-debugger'.
5786 (Qinhibit_debugger): New symbol.
5787 (call_debugger): Bind it instead of Qdebug_on_error.
5788 (maybe_call_debugger): Test Vinhibit_debugger.
5789 (syms_of_eval): Define inhibit-debugger.
5790 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5791 (syms_of_xdisp): Remove inhibit-debug-on-message.
5792
5793 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5794
5795 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5796 If a nonvolatile local variable is written before a _longjmp to
5797 the frame containing the variable, and is read after the _longjmp,
5798 the value read is indeterminate. Some local variables of type
5799 'struct handler' and 'struct catchtag' are used in this way, so
5800 mark each of their slots as volatile if the slot can be set before
5801 _longjmp and read afterwards.
5802 * lisp.h (struct handler): var and chosen_clause are now volatile.
5803 (struct catchtag): val, next, and pdlcount are now volatile.
5804
5805 * bidi.c (bidi_push_it, bidi_pop_it):
5806 * fns.c (copy_hash_table):
5807 * image.c (define_image_type):
5808 * keyboard.c (kbd_buffer_store_event_hold):
5809 * process.c (Fprocess_send_eof):
5810 * xfaces.c (x_create_gc) [HAVE_NS]:
5811 * xgselect.c (xg_select):
5812 Prefer assignment to memcpy when either will do.
5813
5814 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5815 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5816 time an item is removed. No need to mark this function 'inline';
5817 the compiler knows better than we do.
5818
5819 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5820
5821 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5822 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5823 to change_frame_size (Bug#12388).
5824 (windowDidResize:): Pass YES to updateFrameSize.
5825
5826 * nsterm.h: Add delay parameter to updateFrameSize.

5828 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5829
5830 Discard killed buffers from deleted window and frame objects.
5831 This reduces an amount of references to killed buffers and
5832 helps GC to reclaim them faster.
5833 * alloc.c (discard_killed_buffers): New function.
5834 (mark_object): Use it for deleted windows and frames.
5835 (mark_object): If symbol's value is set up for a killed buffer
5836 or deleted frame, restore its global binding.
5837 * data.c (swap_in_global_binding): Add GC notice.
5838 (swap_in_symval_forwarding): Use convenient set_blv_where.
5839 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5840 * window.h: ... to here.
5841
5842 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5843
5844 Convenient macro to check whether the buffer is live.
5845 * buffer.h (BUFFER_LIVE_P): New macro.
5846 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5847 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5848
5849 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5850
5851 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5852 composition cases (Bug#12364).
5853
5854 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5855 overhang of succeeding glyphs overlapping box cursor.
5856
5857 * w32term.c (x_draw_glyph_string): Likewise.
5858
5859 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5860
5861 Simplify, document, and port floating-point (Bug#12381).
5862 The porting part of this patch fixes bugs on non-IEEE platforms
5863 with frexp, ldexp, logb.
5864 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5865 Now static.
5866 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5867 support, by removing commented-out code and briefly listing the
5868 C89 functions excluded. The commented-out stuff was confusing
5869 maintenance, e.g., we thought we needed cbrt but it was commented out.
5870 (logb): Remove decl; no longer needed.
5871 (isfinite): New macro, if not already supplied.
5872 (isnan): Don't replace any existing macro.
5873 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5874 are present on all C89 platforms.
5875 (Ffrexp): Do not special-case zero, as frexp does the right thing
5876 for that case.
5877 (Flogb): Do not use logb, as it doesn't have the desired meaning
5878 on hosts that use non-base-2 floating point. Instead, stick with
5879 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5880 frexp, to avoid getting an unspecified result.
5881
5882 * xdisp.c (Qinhibit_debug_on_message): Now static.
5883
5884 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5885
5886 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5887 NSBezierPath (Bug#12131).
5888
5889 2012-09-10 Chong Yidong <cyd@gnu.org>
5890
5891 * fns.c (Fdelq, Fdelete): Doc fix.
5892
5893 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5894
5895 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5896 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5897
5898 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5899
5900 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5901 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5902 Use it.
5903
5904 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5905
5906 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5907 left fringe if the window has a left margin. This avoids leaving
5908 traces of the cursor because its leftmost pixel is not drawn over.
5909
5910 * dispnew.c (update_window_line): When the left margin area of a
5911 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5912 that screen line. (Bug#12277)
5913
5914 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5915
5916 Assume C89 or later for math functions (Bug#12381).
5917 This simplifies the code, and makes it a bit smaller and faster,
5918 and (most important) makes it easier to clean up signal handling
5919 since we can stop worring about floating-point exceptions in
5920 library code. That was a problem before C89, but the problem
5921 went away many years ago on all practical Emacs targets.
5922 * data.c, image.c, lread.c, print.c:
5923 Don't include <math.h>; no longer needed.
5924 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5925 might be autoconfigured, as that never happens.
5926 * data.c (fmod):
5927 * doprnt.c (DBL_MAX_10_EXP):
5928 * print.c (DBL_DIG):
5929 Remove. C89 or later always defines these.
5930 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5931 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5932 (arith_error, domain_error, domain_error2):
5933 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5934 no longer needed -- we simply return what C returns. All uses removed.
5935 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5936 the wrapped code.
5937 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5938 Remove. All uses expanded, as these macros are no longer used
5939 more than once and are now more trouble than they're worth.
5940 (Ftan): Use tan, not sin / cos.
5941 (Flogb): Assume C89 frexp.
5942 (fmod_float): Assume C89 fmod.
5943 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5944 (init_floatfns): Remove. All uses removed.
5945
5946 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5947
5948 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5949 compositeToPoint for OSX < 10.6 (Bug#12390).
5950
5951 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5952
5953 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5954 This produces more-accurate results.
5955
5956 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5957
5958 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5959 changes (Bug#12088).

5965 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5966
5967 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5968 in the internal border.
5969 (x_set_window_size): Remove static variables and their usage.
5970 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5971 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5972 Remove fringe/internal border adjustment (Bug#11052).
5973 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5974 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5975 (ns_fix_rect_ibw): Remove.
5976 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5977 (ns_dumpglyphs_box_or_relief): Ditto.
5978 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5979 adjustment.
5980 (ns_dumpglyphs_image): Ditto.
5981 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5982 border adjustment.
5983 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5984 their usage. Add fringe_extended_p and its use as in other terms.
5985 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5986 scroll bar was removed.
5987 (updateFrameSize): New function.
5988 (windowDidResize): Move code to updateFrameSize and call it.
5989
5990 * nsterm.h (EmacsView): Add updateFrameSize.
5991
5992 2012-09-07 Chong Yidong <cyd@gnu.org>
5993
5994 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).

6000 More signal-handler cleanup (Bug#12327).
6001 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6002 Problem introduced when merging patches. Noted by Eli Zaretskii in
6003 <http://bugs.gnu.org/12327#67>.
6004 * floatfns.c: Comment fix.
6005 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6006 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6007 and anyway the declaration is harmless even if SIGDANGER is not defined.
6008 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6009 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6010 source files not surprisingly expected syssignal.h to define, or
6011 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6012 Include <sys/ioctl.h>, for FIONREAD.
6013 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6014 This eliminates a problem whereby other files mysteriously had
6015 to include "syssignal.h" before including "systty.h" if they
6016 wanted to use "#ifdef SIGIO".
6017
6018 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6019
6020 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6021
6022 * w32.c (sigemptyset): Empty the set.
6023 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6024
6025 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6026
6027 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6028
6029 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6030 (mark_object): Likewise for frame objects.
6031
6032 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6033
6034 * syssignal.h (handle_on_main_thread): Always declare,
6035 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6036 This ports to platforms without HAVE_PTHREAD.
6037
6038 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6039
6040 Signal-handler cleanup (Bug#12327).
6041 Emacs's signal handlers were written in the old 4.2BSD style with
6042 sigblock and sigmask and so forth, and this led to some
6043 inefficiencies and confusion. Rewrite these to use
6044 pthread_sigmask etc. without copying signal sets around. Also,
6045 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6046 'signal', and instead use functions that do not attempt to take
6047 over the system name space. This patch causes Emacs's text
6048 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6049 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6050 Do not include <signal.h> or "syssignal.h", as these
6051 modules do not use signals.
6052 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6053 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6054 Do not include <signal.h>, as "syssignal.h" does that for us now.
6055 * atimer.c (sigmask_atimers): New function.
6056 (block_atimers, unblock_atimers): New functions,
6057 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6058 All uses replaced.
6059 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6060 no longer needed here.
6061 * emacs.c (main): Inspect existing signal handler with sigaction,
6062 so that there's no need to block and unblock SIGHUP.
6063 * sysdep.c (struct save_signal): New member 'action', replacing
6064 old member 'handler'.
6065 (save_signal_handlers, restore_signal_handlers):
6066 Use sigaction instead of 'signal' to save and restore.
6067 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6068 New function. All users of 'signal' modified to use set_sighandler
6069 if they're writeonly, and to use sys_signal if they're read+write.
6070 (emacs_sigaction_init, forwarded_signal): New functions.
6071 (sys_signal): Remove. All uses replaced by calls to sigaction
6072 and emacs_sigaction_init, or by direct calls to 'signal'.
6073 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6074 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6075 all uses replaced by pthread_sigmask etc. calls.
6076 * syssignal.h: Include <signal.h>.
6077 (emacs_sigaction_init, forwarded_signal): New decls.
6078 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6079 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6080 (sigmask, sys_sigmask): Remove; no longer needed.
6081 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6082 (sigblock, sigunblock, sigfree):
6083 (sigsetmask) [!defined sigsetmask]:
6084 Remove. All uses replaced by pthread_sigmask.
6085 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6086 no longer need to be replaced, and its typical old uses
6087 are now done via emacs_sigaction_init and sigaction.
6088 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6089 (sys_sigdel): Remove; unused.
6090 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6091
6092 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6093
6094 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6095 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6096
6097 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6098
6099 Explicitly mark buffer_defaults and buffer_local_symbols.
6100 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6101 mark_local_symbols here.
6102 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6103 since special buffers aren't marked here any more.
6104 (allocate_buffer): Chain new buffer with all_buffers here...
6105 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6106 not here.
6107 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6108 (syms_of_buffer): Remove staticpro of the above.
6109 (init_buffer_once): Set names for buffer_defaults and
6110 buffer_local_symbols.
6111
6112 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>

6116 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6117 (generate_otf_features, font_check_otf_features, font_check_otf)
6118 (font_match_p, font_list_entities, font_at):
6119 * fontset.c (fontset_id_valid_p, reorder_font_vector
6120 (fontset_find_font, Fset_fontset_font)
6121 (face_suitable_for_char_p) [0]:
6122 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6123 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6124 (m17n_flt_initialized, ftfont_shape_by_flt):
6125 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6126 * nsfont.m (nsfont_draw):
6127 * w32font.c (w32font_draw):
6128 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6129 Use bool for booleans.
6130 * font.h: Adjust to above API changes.
6131 (struct font, struct font_driver, struct font_driver_list):
6132 Use bool for booleans.
6133 (struct font): Remove useless member encoding_type.
6134 All users removed.
6135 * fontset.c, xftfont.c: Omit unnecessary static decls.
6136
6137 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6138
6139 * alloc.c (mark_object): Revert window marking code
6140 since it's unsafe for the Fset_window_configuration.
6141
6142 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6143
6144 Fix race conditions with signal handlers and errno (Bug#12327).
6145 Be more systematic about preserving errno whenever a signal
6146 handler returns, even if it's not in the main thread. Do this by
6147 renaming signal handlers to distinguish between signal delivery
6148 and signal handling. All uses changed.
6149 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6150 * data.c (deliver_arith_signal): Rename from arith_error.
6151 * dispnew.c (deliver_window_change_signal): Rename from
6152 window_change_signal.
6153 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6154 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6155 * keyboard.c (deliver_input_available_signal): Rename from
6156 input_available_signal.
6157 (deliver_user_signal): Rename from handle_user_signal.
6158 (deliver_interrupt_signal): Rename from interrupt_signal.
6159 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6160 (deliver_child_signal): Rename from sigchld_handler.
6161 * atimer.c (handle_alarm_signal):
6162 * data.c (handle_arith_signal):
6163 * dispnew.c (handle_window_change_signal):
6164 * emacs.c (handle_fatal_signal, handle_danger_signal):
6165 * keyboard.c (handle_input_available_signal):
6166 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6167 * process.c (handle_pipe_signal, handle_child_signal):
6168 New functions, with the actual signal-handling code taken from the
6169 original respective signal handlers, sans the sporadic attempts to
6170 preserve errno, since that's now done by handle_on_main_thread.
6171 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6172 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6173 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6174 Move to sysdep.c.
6175 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6176 Move initialization of main_thread to sysdep.c's init_signals.
6177 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6178 our usage, and simplifies the mainline code.
6179 (record_child_status_change): New static function, as a helper
6180 for handle_child_signal, and with most of the old child handler's
6181 contents.
6182 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6183 (handle_child_signal): Use the above.
6184 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6185 Moved here from emacs.c.
6186 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6187 code moved here from emacs.c's main function.
6188 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6189 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6190 This lets callers save and restore errno properly.
6191
6192 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6193
6194 Remove redundant or unused things here and there.
6195 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6196 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6197 * editfns.c (Fcompare_buffer_substrings): Likewise.
6198 * frame.h (struct terminal, struct font_driver_list):
6199 Remove redundant declarations.
6200 * window.h (Qleft, Qright): Likewise.
6201
6202 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6203
6204 Do not mark objects from deleted buffers, windows and frames.
6205 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6206 (mark_object): Likewise for windows and frames.
6207
6208 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6209
6210 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6211 buffer_defaults and buffer_local_symbols as valid objects.
6212 Return special value to denote them.
6213
6214 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6215
6216 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6217 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6218 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6219 (file_name_absolute_p, Fsubstitute_in_file_name):
6220 (check_executable, check_writable, Ffile_accessible_directory_p)
6221 (Fset_file_selinux_context, Fdefault_file_modes)
6222 (Finsert_file_contents, choose_write_coding_system)
6223 (Fwrite_region, build_annotations, a_write, e_write)
6224 (Fdo_auto_save):
6225 * filelock.c (boot_time_initialized, get_boot_time)
6226 (get_boot_time_1, lock_file_1, within_one_second):
6227 * floatfns.c (in_float):
6228 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6229 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6230 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6231 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6232 * window.c (compare_window_configurations):
6233 Use bool for booleans.
6234 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6235 (Fdefault_file_modes): Now mode_t, not int, for modes.
6236 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6237 (internal_delete_file): Now returns void, not a (boolean) int,
6238 since nobody was looking at the return value.
6239 * lisp.h, window.h: Adjust to above API changes.
6240
6241 * xdisp.c (set_message): Simplify and reindent last change.
6242
6243 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6244
6245 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6246
6247 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6248
6249 * eval.c (call_debugger): Make the function non-static so that we
6250 can call it from set_message.
6251
6252 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6253 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6254
6255 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6256
6257 Give more-useful info on a fatal error (Bug#12328).
6258 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6259 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6260 of doing the work ourselves.
6261 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6262 do most of the work.
6263 (fatal_error_backtrace): New function, taken from the guts
6264 of the old fatal_error_signal, but with a new option to output
6265 a backtrace.
6266 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6267 info about the signal than just its number.
6268 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6269 * sysdep.c: Include <execinfo.h>
6270 (emacs_backtrace): New function, taken partly from the previous
6271 code of the 'die' function.
6272 (emacs_abort): Call fatal_error_backtrace rather than abort.
6273
6274 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6275
6276 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6277 eager (load-time) macro-expansion.
6278 * lisp.mk (lisp): Add macroexp.
6279
6280 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6281
6282 Simplify redefinition of 'abort' (Bug#12316).
6283 Do not try to redefine the 'abort' function. Instead, redo
6284 the code so that it calls 'emacs_abort' rather than 'abort'.
6285 This removes the need for the NO_ABORT configure-time macro
6286 and makes it easier to change the abort code to do a backtrace.
6287 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6288 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6289 Remove; sysdep.c's emacs_abort now takes its place.
6290 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6291 'abort' changed to use 'emacs_abort'.
6292 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6293 (abort) [!defined abort]: Rename to ...
6294 (emacs_abort): ... new name.
6295 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6296 the place of the old 'abort' in emacs.c.
6297 * w32.c, w32fns.c (abort): Do not #undef.
6298 * w32.c (emacs_abort): Rename from w32_abort.
6299
6300 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6301
6302 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6303 offsets[j].dv, since the y axis of the screen coordinates points
6304 down, while the y axis of the font definition coordinates points
6305 up. This fixes display of Arabic diacritics such as KASRA and
6306 KASRATAN. (Bug#11860)
6307
6308 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6309
6310 Be more systematic about _setjmp vs setjmp.
6311 * alloc.c (test_setjmp, mark_stack):
6312 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6313 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6314 (png_load, my_error_exit, jpeg_load):
6315 * process.c (send_process_trap, send_process):
6316 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6317 The underscored versions are up to 30x faster on some hosts.
6318 Formerly, the code used setjmp+longjmp sometimes and
6319 _setjmp+_longjmp at other times, with no particular reason to
6320 prefer setjmp+longjmp.
6321
6322 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6323
6324 Fix minor problem found by static checking.
6325 * buffer.c (Fdelete_all_overlays): Return nil.
6326
6327 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6328
6329 * buffer.c (Fdelete_all_overlays): New function.
6330
6331 2012-09-03 Chong Yidong <cyd@gnu.org>
6332
6333 * gtkutil.c: Add extern decl for Qxft.
6334
6335 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6336
6337 * emacs.c, eval.c: Use bool for boolean.
6338 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6339 (malloc_using_checking) [DOUG_LEA_MALLOC]:

6346 * process.c (read_process_output, exec_sentinel):
6347 Use bool for booleans.
6348 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6349 All callers changed.
6350 * eval.c (interactive_p): Omit always-true boolean argument
6351 EXCLUDE_SUBRS_P. All callers changed.
6352 * dispextern.h, lisp.h: Reflect above API changes.
6353 * firstfile.c (dummy): Use the address of 'main', whose signature
6354 won't change, instead of the address of 'initialize', whose
6355 signature just changed from int to bool.
6356 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6357 * msdos.c (fatal_error_in_progress): ... from here.
6358 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6359 of incrementing it.
6360 (redisplay_internal, unwind_redisplay): Simply clear
6361 REDISPLAYING_P when unwinding, instead of saving its previous,
6362 always-false value and then restoring it.
6363
6364 Clean up some extern decls.
6365 Mostly, this hoists extern decls out of .c files and into .h files.
6366 That way, we're more likely to catch errors if the interfaces change.
6367 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6368 declare xg_mark_data.
6369 * dispextern.h (x_frame_parm_handlers):
6370 * font.h (Qxft):
6371 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

6376 * doc.c (Qclosure):
6377 * eval.c (Qlexical_binding):
6378 * fns.c (time) [!HAVE_UNISTD_H]:
6379 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6380 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
6381 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
6382 * lread.c (Qinternal_interpreter_environment):

6387 * xfont.c (x_clear_errors):
6388 * xterm.c (x_frame_parm_handlers):
6389 Remove now-redundant extern decls.
6390 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6391 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6392 Now static.
6393 * xfaces.c: Remove unnecessary static decls.
6394 * xterm.c (updating_frame): Remove decl of nonexistent object.
6395
6396 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6397 when building globals.h, as the objects that are not built on
6398 this host are not needed to compile C files on this host.
6399
6400 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6401
6402 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
6403
6404 * frame.h: Add missing prototype for x_wm_set_size_hint.
6405
6406 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6407
6408 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

6410 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6411 (Fsubstitute_command_keys):
6412 * editfns.c (region_limit, find_field, Fconstrain_to_field)
6413 (save_excursion_save, save_excursion_restore)
6414 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)

6424 * intervals.c (intervals_equal, balance_possible_root_interval)
6425 (adjust_intervals_for_insertion, merge_properties_sticky)
6426 (graft_intervals_into_buffer, lookup_char_property)
6427 (adjust_for_invis_intang, set_point_both)
6428 (get_property_and_range, compare_string_intervals)
6429 (set_intervals_multibyte_1, set_intervals_multibyte):
6430 * keyboard.c (decode_timer):
6431 Use bool for boolean.
6432 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6433 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
6434
6435 2012-09-02 Chong Yidong <cyd@gnu.org>
6436
6437 * keymap.c (push_key_description): Print M-TAB as C-M-i
6438 (Bug#11758).
6439
6440 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6441
6442 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6443 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
6444 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

6448 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
6449
6450 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6451
6452 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6453 more than one grapheme cluster passed to the shaper: compute the
6454 offset adjustment values separately for each cluster. (Bug#11860)
6455
6456 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6457 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6458 about implicit conversions from integer to pointer.
6459
6460 2012-09-01 Daniel Colascione <dancol@dancol.org>
6461
6462 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6463 system used too early.
6464
6465 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

6473
6474 2012-09-01 Daniel Colascione <dancol@dancol.org>
6475
6476 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
6477 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
6478 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
6479 x_wm_set_size_hint, x_query_colors, x_real_positions,
6480 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
6481 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
6482 all of which have been moved to common code.
6483
6484 * xfaces.c: Include TERM_HEADER instead of listing all possible
6485 window-system headers.
6486
6487 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
6488 to match header.
6489
6490 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
6491 directly accessing frame internals.
6492
6493 * w32font.h: Include font.h. Define syms_of_w32font and
6494 globals_of_w32font.
6495
6496 * process.c: Include TERM_HEADER instead of listing all possible
6497 window-system headers.
6498
6499 * nsterm.h: Remove declarations now in frame.h.
6500 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
6501
6502 * menu.c: Include TERM_HEADER instead of listing all possible
6503 window-system headers.
6504
6505 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6506 window system.
6507
6508 * keyboard.c: Include TERM_HEADER instead of listing all possible
6509 window-system headers.
6510
6511 * image.c: Include TERM_HEADER instead of listing all possible
6512 window-system headers. Declare Vlibrary_cache when compiling for
6513 Windows.
6514
6515 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6516 window system declarations.
6517
6518 * frame.h: Move common functions here: set_frame_menubar,
6519 x_set_window_size, x_sync, x_get_focus_frame,
6520 x_set_mouse_position, x_set_mouse_pixel_position,
6521 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6523 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,
6524 x_activate_menubar, x_real_positions, x_bitmap_icon,
6525 x_set_menu_bar_lines, free_frame_menubar, x_free_frame_resources,
6526 and x_query_colors.
6527
6528 * frame.c: Include TERM_HEADER instead of listing all possible
6529 window-system headers.
6530
6531 * font.c: Include TERM_HEADER instead of listing all possible
6532 window-system headers.
6533
6534 * emacs.c: Include TERM_HEADER.
6535
6536 * dispnew.c: Include TERM_HEADER instead of listing all possible
6537 window-system headers.
6538
6539 * ccl.h: Include character.h.
6540
6541 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
6542 the current window system; include in list of objects to link into
6543 Emacs.
6544
6545 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6546
6547 Remove mark_ttys function and fix tty_display_info initialization.
6548 * lisp.h (mark_ttys): Remove prototype.
6549 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6550 to mark_ttys because all possible values of 'top_frame' slot are
6551 the frames which are reachable from Vframe_list.
6552 * term.c (mark_ttys): Remove.
6553 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6554
6555 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6556
6557 Change struct frame bitfields from unsigned char to unsigned.
6558 * frame.h (struct frame): Change type of 'display_preempted',
6559 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
6560 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6561 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6562 bitfields from unsigned char to unsigned.
6563

6585
6586 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6587
6588 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6590 (windowShouldClose:): Set window_closed.
6591 (dealloc): New member, free button_values.
6592 (process_dialog:): Make member function. Remove window argument,
6593 replace window with self. Count buttons and allocate and store values
6594 in button_values.

6608 Add window_closed and button_values. Add void as return value for
6609 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6610 Add process_dialog as new member.
6611
6612 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6613
6614 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

6633 nested declaration.
6634
6635 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>

6675 (change_frame_size_1, sit_for):
6676 Use bool for boolean.
6677 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6678 and remove last int (actually boolean) argument, which was always 0.
6679 All callers changed.

6683 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6684 * dired.c (file_name_completion):
6685 Use bool for boolean. (This was missed in an earlier change.)
6686
6687 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6688
6689 * window.c (Fset_window_configuration): Revert first part of

6697 Initialize dialog_return.
6698 (windowShouldClose:): Use stop instead of stopModalWithCode.
6699 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6700 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6701 event.
6702 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
6703 modal loop returns.
6704
6705 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

6717 Use bool for booleans.
6718 * dired.c (file_name_completion):
6719 * process.h (fd_callback):

6721 All uses changed.
6722 * composite.h, lisp.h: Reflect above API changes.
6723

6750 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6751 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6752 not a boolean 'int', since callers never look at the return value.

6755 (emacs_mule_string_char): Remove unused extern decls.
6756 (struct iso_2022_spec, struct coding_system):

6762 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6763
6764 Fix spare memory change (Bug#12286).

6766 (valid_lisp_object_p): Likewise.
6767
6768 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6769
6770 * window.c (Fset_window_configuration): Record any window's old
6771 buffer if it's replaced (see Bug#8789). If the new current
6772 buffer doesn't appear in the selected window, go to its old
6773 point (Bug#12208).
6774
6775 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6776
6777 Special MEM_TYPE_SPARE to denote reserved memory.
6778 * alloc.c (enum mem_type): New memory type.
6779 (refill_memory_reserve): Use new type for spare memory.
6780 This prevents live_cons_p and live_string_p from incorrect
6781 detection of uninitialized objects from spare memory as live.
6782
6783 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6784
6785 Spelling fixes.
6786 * Makefile.in (.PHONY): versioclean -> versionclean.
6787
6788 Remove unused external symbols.
6789 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6790 * window.c (Qwindow_valid_p, decode_valid_window):
6791 Now static, not extern.
6792 * data.c (Qinterval): Remove; unused.
6793 (syms_of_data): Do not define 'interval'.
6794 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6795 * window.h (decode_valid_window):
6796 Remove decls.
6797
6798 * character.c, charset.c, chartab.c: Use bool for booleans.
6799 * character.c (lisp_string_width, string_count_byte8)
6800 (string_escape_byte8):
6801 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6802 (load_charset_map_from_file, map_charset_chars)
6803 (Fdefine_charset_internal, define_charset_internal)
6804 (Fdeclare_equiv_charset, find_charsets_in_text)

6807 (sub_char_table_set, sub_char_table_set_range)
6808 (char_table_set_range, optimize_sub_char_table)
6809 (map_sub_char_table):
6810 Use bool for boolean.
6811 * character.c (str_to_unibyte): Omit last boolean argument; it was
6812 always 0. All callers changed.
6813 * character.h, charset.h: Adjust to match previous changes.
6814 * character.h (char_printable_p): Remove decl of nonexistent function.
6815 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6816 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6817 are all boolean, so make them single-bit bitfields.
6818
6819 * lisp.h (ASET): Remove attempt to detect side effects.
6820 It was meant to be temporary and it often doesn't work,
6821 because when IDX has side effects the behavior of IDX==IDX
6822 is undefined. See Stefan Monnier in
6823 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6824
6825 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6826
6827 * lisp.h (functionp): New function (extracted from Ffunctionp).
6828 (FUNCTIONP): Use it.
6829 * eval.c (Ffunctionp): Use it.
6830
6831 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6832
6833 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6834 as that's faster and simpler than static storage. Don't bother
6835 with the g_main_context_query overhead if g_main_context_pending
6836 says no events are pending.
6837 (gfds, gfds_size): Remove these static vars.
6838 (xgselect_initialize): Remove; no longer needed.
6839 All uses and decls removed.
6840
6841 * emacs.c (fatal_error_signal_hook): Remove.
6842 All uses removed. This leftover from old code was always 0.

6845 * casefiddle.c (casify_object, casify_region):
6846 * casetab.c (set_case_table):

6852
6853 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6854

6856
6857 On assertion failure, print backtrace if available.

6864 * bytecode.c (exec_byte_code):
6865 * callint.c (check_mark, Fcall_interactively):
6866 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6867 (getenv_internal, sync_process_alive, call_process_exited):
6868 * lisp.h (USE_SAFE_ALLOCA):
6869 Use bool for booleans, instead of int.
6870 * lisp.h, process.h: Adjust prototypes to match above changes.
6871 * callint.c (Fcall_interactively): Don't assume the mark's
6872 offset fits in 'int'.
6873
6874 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6875
6876 * buffer.c, buffer.h: Use bool for boolean.
6877 * buffer.c (reset_buffer_local_variables)
6878 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6879 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6880 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6881 (overlay_touches_p, overlay_strings, Foverlay_put)
6882 (report_overlay_modification, call_overlay_mod_hooks):
6883 (mmap_enlarge, mmap_set_vars):
6884 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6885 Use bool for booleans, instead of int.
6886 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6887 since the 1-or-0 return value is always ignored anyway.
6888 (mmap_initialized_p):
6889 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6890 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6891
6892 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6893
6894 * bidi.c: Use bool for boolean.
6895 This is a bit more readable, and makes the text segment of bidi.o
6896 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6897 Presumably it's faster too.
6898 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6899 Now bool.
6900 (bidi_cache_find_level_change, bidi_cache_iterator_state)

6904 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6905 Use bool for booleans, instead of int.
6906 * dispextern.h (bidi_init_it, bidi_paragraph_init)

6917 * atimer.h: Include <stdbool.h>.
6918
6919 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6920
6921 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6922 compile time tests instead of run time tests on systems that do
6923 not use them.
6924 (FRAME_MAC_P): Remove leftover from deleted code.
6925 * frame.c (syms_of_frame): Remove leftover from deleted code.
6926
6927 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6930
6931 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6932
6933 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6934 Otherwise, the compiler complains about (A?B:C) where B is void
6935 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6936 (fontset_add): Return void, for FONTSET_ADD.
6937
6938 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6939

6950 Use bool for booleans, instead of int.
6951 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6952 Remove unused local.
6953 * alloc.c (PURE_POINTER_P):
6954 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.

6961 * lread.c (readchar, read1):
6962 * print.c (Fprin1_to_string):
6963 * xdisp.c (push_message):
6964 Use bool for booleans affected directly or indirectly by
6965 alloc.c's changes.
6966
6967 Make recently-introduced setters macros.
6968 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6969 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6970 (set_fontset_default, set_fontset_fallback): Rename from their
6971 upper-case counterparts, and make them functions rather than macros.
6972 This is more consistent with the other recently-introduced setters.
6973 These don't need to be inline, since they're local.
6974
6975 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6976
6977 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6978 the loop (Bug#12247).
6979
6980 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6981
6982 * lisp.h (vcopy): Use memcpy rather than our own loop.
6983 This fixes a performance regression introduced by the recent
6984 addition of vcopy. This means 'vcopy' will need to be modified
6985 for a copying collector, but that's OK. Also, tighten the
6986 checking in the assertion.
6987
6988 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6989
6990 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6991 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6992 non-base glyph for the width of the base character, according to
6993 what x_draw_composite_glyph_string_foreground expects.
6994 Generate WADJUST value according to composition_gstring_width's
6995 expectations, to produce correct width of the composed character.
6996 Reverse the sign of the DU offset produced by ScriptPlace.
6997
6998 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6999

7007 * fns.c (Ffillarray): Use ASET.
7008 * keyboard.c (timer_check_2): Use AREF and ASET.
7009 (append_tool_bar_item, Frecent_keys): Use vcopy.
7010 * lread.c (read_vector): Use ASET.
7011 * msdos.c (Frecent_doskeys): Use vcopy.
7012 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7013 (Finternal_merge_in_global_face): Use ASET and vcopy.
7014 * xfont.c (xfont_list_pattern): Likewise.
7015
7016 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7017
7018 * window.c (Fwindow_point): For the selected window always return
7019 the position of its buffer's point.
7020 (Fset_window_point): For the selected window always go in its
7021 buffer to the specified position.
7022
7023 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7024
7025 Setter macros for fontsets.
7026 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7027 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7028 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7029 Adjust users.
7030
7031 2012-08-20 Glenn Morris <rgm@gnu.org>
7032
7033 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7034 Don't assume that `ln -f' works.
7035
7036 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7037
7038 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7039 and later about non-assignments with no effect. See discussion at
7040 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7041 details.
7042
7043 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7044
7045 Inline setter functions for Lisp_Objects slots of struct specbinding.
7046 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7047 Adjust users.
7048
7049 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7050
7051 * window.c (select_window): Always make selected window's buffer
7052 current.
7053
7054 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7055
7056 Use AREF and ASET for docstrings of category tables.
7057 * category.h (CATEGORY_DOCSTRING): Use AREF.
7058 (SET_CATEGORY_DOCSTRING): Use ASET.
7059 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7060
7061 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7062

7065 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7066 (set_hash_key_and_value, set_hash_index, set_hash_next)
7067 (set_hash_hash): New functions.
7068 * charset.c, fns.c: Adjust users.
7069
7070 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7071
7072 Inline getter and setter functions for per-buffer values.
7073 * buffer.h (per_buffer_default, set_per_buffer_default)
7074 (per_buffer_value, set_per_buffer_value): New functions.
7075 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7076 * buffer.c, data.c: Adjust users.
7077
7078 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7079
7080 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7081
7082 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7083
7084 Rely on <config.h> + <unistd.h> to declare 'environ',
7085 as gnulib does this if the system doesn't.
7086 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7087 Remove declaration. MS-Windows declares it on stdlib.h which is
7088 included by conf_post.h.
7089 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7090 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7091 * vm-limit.c: Include <unistd.h>, for 'environ'.
7092
7093 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7094 (start_of_data): Remove decl; mem-limits.h provides it.
7095
7096 * xdisp.c (handle_invisible_prop): Make it a bit faster
7097 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7098
7099 2012-08-19 Chong Yidong <cyd@gnu.org>
7100
7101 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7102 ends (Bug#3874).
7103
7104 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7105
7106 * .gdbinit: Use call instead of set when calling a function in the
7107 inferior.
7108
7109 * data.c (set_internal): Don't use set_blv_found.
7110 (Fkill_local_variable): Likewise.
7111
7112 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7113
7114 * nsfont.m (ns_ascii_average_width): Ensure the string
7115 ascii_printable is initialized with a null-terminated character
7116 array. Otherwise, it can contain undesired extra characters.
7117
7118 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7119
7120 port new setting code to Sun C 5.8 2005/10/13
7121 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7122 Return void, not Lisp_Object. Otherwise, the compiler
7123 complains about (A?B:C) where B is void and C is Lisp_Object
7124 when compiling CHAR_TABLE_SET, due to the recent change to
7125 the API of sub_char_table_set_contents.
7126
7127 2012-08-18 Chong Yidong <cyd@gnu.org>
7128
7129 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7130 for the string case (Bug#3874).
7131
7132 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7133
7134 * buffer.h (BSET): Remove (Bug#12215).

7181
7182 * window.h (WSET): Remove (Bug#12215).

7245 (fset_tool_bar_position, fset_tool_bar_window): New functions.
7246 * frame.c (FRAME_INLINE):
7247 Define to EXTERN_INLINE, so that the corresponding functions
7248 are compiled into code.

7250
7251 A few more naming-convention fixes for getters and setters.
7252 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,

7254 (set_buffer_overlays_after): Move here from buffer.h, and rename
7255 from buffer_overlays_set_after.
7256 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.
7257 All uses changed.
7258 (set_buffer_intervals): Rename from buffer_set_intervals.

7280 (set_char_table_ascii, set_char_table_defalt, set_char_table_parent)
7281 (set_char_table_purpose): New functions,
7282 replacing CSET. All uses changed. For example, replace
7283 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
7284 "set_char_table_parent (char_table, parent);".
7285 The old version was confusing because it used the same name
7286 'parent' for two different things.
7287
7288 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
7289

7318
7319 2012-08-17 Juanma Barranquero <lekktu@gmail.com>
7320
7321 * makefile.w32-in (C_CTYPE_H): New macro.
7322 (LISP_H, $(BLD)/ccl.$(O), $(BLD)/doc.$(O), $(BLD)/w32console.$(O)):
7323 ($(BLD)/fontset.$(O), $(BLD)/frame.$(O), $(BLD)/composite.$(O)):
7324 ($(BLD)/sysdep.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7325
7326 2012-08-16 Paul Eggert <eggert@cs.ucla.edu>
7327
7328 Use ASCII tests for character types.
7329 * category.c, dispnew.c, doprnt.c, editfns.c, syntax.c, term.c:
7330 * xfns.c, xterm.c:
7331 Don't include <ctype.h>; was not needed.
7332 * charset.c, doc.c, fileio.c, font.c, frame.c, gtkutil.c, image.c:
7333 * sysdep.c, xfaces.c:

7347 * nsterm.m (ns_xlfd_to_fontname):
7348 * sysdep.c (system_process_attributes):
7349 * xfaces.c (hash_string_case_insensitive):
7350 Use C-locale tests instead of locale-specific tests for character
7351 types, since we want the ASCII interpretation here, not the
7352 interpretation suitable for whatever happens to be the current locale.
7353
7354 2012-08-16 Martin Rudalics <rudalics@gmx.at>

7958 * w32.c (init_environment): Change the default values of many
7959 environment variables in dflt_envvars[] to NULL, to avoid pushing
7960 them into environment when they were not already defined.
7961 Remove the code that deletes site-lisp subdirectories from the default
7962 value of EMACSLOADPATH, as it is no longer needed.
7963 (check_windows_init_file): Now external, not static.
7964 Use Vload_path as is, without adding anything, as this function is now
7965 called when Vload_path is already set up.
7966
7967 * w32.h (check_windows_init_file): Add prototype.
7968
7969 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
7970 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
7971 compatibility with Posix platforms.
7972 (main): Move the call to check_windows_init_file to here from
7973 w32.c.
7974 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
7975 any, in the DEFALT argument into the root of the Emacs build or
7976 installation tree, as appropriate.
7977

7984
7985 * msdos.c (dos_set_window_size, IT_update_begin)

7994
7995 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
7996
7997 Remove unnecessary casts involving pointers.
7998 These casts are no longer needed now that we assume C89 or later,
7999 since they involve casting to or from void *.
8000 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8001 (make_pure_float, make_pure_vector):

8012 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8013 Remove unnecessary pointer casts.
8014 * alloc.c (record_xmalloc): New function.
8015 * lisp.h (record_xmalloc): New decl.
8016 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8017 more like a function. This is because the pointer cast is not
8018 needed. All uses changed.
8019 * print.c (print_string, print_error_message): Avoid length recalc.
8020
8021 Improve fix for macroexp crash with debugging (Bug#12118).
8022 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8023 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8024 not supposed to be invoked from the garbage collector.
8025 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8026 (gc_aset): New function, which is like ASET but can be
8027 used in the garbage collector.
8028 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8056 with addition of handling of symlinks and support for 'lstat'.
8057 If possible, get file's attributes and security information by
8058 handle, not by name. Produce S_IFLNK bit for symlinks, when
8059 called from 'lstat'.
8060 (stat, lstat): New functions, call 'stat_worker'.
8061 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8062 symlinks when the underlying filesystem supports them.
8063

8066 Fix macroexp crash on Windows with debugging (Bug#12118).
8067 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8068 checking subscripts; problem introduced with the recent
8069 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8070 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8071 since it's used in non-static inline functions now.
8072
8073 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8074 Don't assume buffer size fits in 'int'. Remove unused local.

8124
8125 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8126 This how ASET and AREF are supposed to work, and makes
8127 it easier to think about future improvements. See
8128 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

8571 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8572 Zaretskii in <http://bugs.gnu.org/12036#13>.
8573 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8574 needed now that we have gdb_make_enums_visible.
8575 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8576 (enum enum_USE_LSB_TAG):
8577 New enum types, packaging up enums that need to be exported to GDB.
8578
8579 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8580
8581 Utility function to make a list from specified amount of objects.
8582 * lisp.h (enum constype): New datatype.
8583 (listn): New prototype.
8584 * alloc.c (listn): New function.
8585 (Fmemory_use_count, syms_of_alloc): Use it.
8586 * buffer.c (syms_of_buffer): Likewise.

8599
8600 Fast save_excursion_save and save_excursion_restore.
8601 * lisp.h (struct Lisp_Excursion): New data type.
8602 (PVEC_EXCURSION): New pseudovector type.
8603 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8604 to deal with it. Adjust comments.
8605 (init_marker, attach_marker): New prototype.
8606 (unchain_marker): Adjust prototype.
8607 * marker.c (attach_marker): Change to global.

8615 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8616
8617 Fix export of symbols to GDB (Bug#12036).
8618 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8619 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8620 emacs.c, as this is a more-suitable home. Had this been done earlier
8621 the fix for 12036 would have avoided some of the problems noted in
8622 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8623 would have been more obvious.
8624 * emacs.c: Do not include <verify.h>; no longer needed.
8625 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

8630 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8631 (DATA_SEG_BITS): Use it.
8632 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8633 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8634 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8635 not be usable in #if. This simplifies things.
8636
8637 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8638
8639 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8643 Simplify export of symbols to GDB (Bug#12036).
8644 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8645 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8646 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8647 Adjust to changes in lisp.h and emacs.c, by using
8648 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8649 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8650 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8651 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8652 instead of gdb_valbits.
8653 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8654 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8655 instead of gdb_array_mark_flag.
8656 (xboolvector): Get size from $->size, not $->header.size.
8657 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8658 (xreload, hook-run, hookpost-run): Remove.
8659 * emacs.c: Include <verify.h>.
8660 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8661 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8662 Remove.
8663 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8664 (gdb_USE_LSB_TAG): New enum constants.
8665 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8666 Also define these as enum constants, so they're visible to GDB.
8667 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8668 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8669 as constants, so they're visible to GDB.
8670 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8671 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8672 Now enum constants, not macros, so they're visible to GDB.
8673 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8674 more convenient now. All uses changed.
8675 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8676 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8677

8688 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8689
8690 Use typedef for EMACS_INT, EMACS_UINT.
8691 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8692 than macros. This simplifies debugging in the usual case, since
8693 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8694 and it allows expressions involving EMACS_INT casts.
8695 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8696
8697 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8707 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8708
8709 Adjust buffer text indirection counters at the end of Fkill_buffer.
8710 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8711 buffer is definitely dead. This should really fix an issue reported
8712 by Christoph Scholtes again. (Bug#12007).
8713 (init_buffer_once): Initialize indirection counters of
8714 buffer_defaults and buffer_local_symbols (for sanity and safety).
8715
8716 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8717
8718 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8719 and continuation glyphs on tooltip frames, leave them at zero.

8727
8728 2012-07-23 Eli Zaretskii <eliz@gnu.org>
8729
8730 * print.c (print_object): Don't crash when a frame's name is nil
8731 or invalid. (Bug#12025)
8732
8733 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
8734 it signals an error when a tooltip frame is being created.
8735
8736 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8737
8738 Cleanup miscellaneous objects allocation and initialization.
8739 * alloc.c (allocate_misc): Change to static. Add argument to
8740 specify the subtype. Adjust comment and users.
8741 (build_overlay): New function.
8742 * buffer.c (copy_overlays, Fmake_overlay): Use it.
8743 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
8744 (allocate_misc): Remove prototype.
8745 (build_overlay): Add prototype.
8746
8747 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8748
8749 Swap buffer text indirection counters in Fbuffer_swap_text.
8750 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8751 This avoids crash reported by Christoph Scholtes at
8752 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8753
8754 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8755
8756 * nsmenu.m (Popdown_data): New struct.

8761 and autorelease them. Also autorelease img and matrix (Bug#12005).
8762 (dealloc): Remove (Bug#12005).

8764 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8765
8766 Adjust consing_since_gc when objects are explicitly freed.

8780
8781 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8782 as it's limited by the amount of memory, not by INT_MAX.

8785
8786 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

8789 for the reasons.
8790
8791 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
8792 info.dwItemData. Fixes crashes on 64-bit Windows.
8793 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
8794
8795 2012-07-21 Jan Djärv <jan.h.d@swipnet.se>
8796

8868 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8869 'for_each_per_buffer_object_at'.

8872 that they're special.
8873

8913
8914 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
8915
8916 Fix bug that created negative-length intervals.
8917 * intervals.c (merge_interval_right, merge_interval_left):
8918 Do not zero out this interval if it is absorbed by its children,
8919 as this interval's total length doesn't change in that case. See
8920 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8921

8923
8924 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8925 when invoking (make-bool-vector N t) and N is a positive

8929 * alloc.c (bool_header_size): New constant.
8930 (header_size, word_size): Move earlier, as they're now used earlier.
8931 Use 'word_size' in a few more places, where it's appropriate.
8932 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
8933 padding before the data member of a bool vector.
8934 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
8935 than doing the check by hand with an abort ().
8936
8937 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8938
8939 * eval.c (Fdefvar): Don't check constants since we only set the var if

8943 * keyboard.c (command_loop_1): Set it.

9439
9440 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,

9510 * s/aix4-2.h (unix): Remove; no longer needed.
9511
9512 EMACS_TIME simplification (Bug#11875).
9513 This replaces macros (which typically do not work in GDB)
9514 with functions, typedefs and enums, making the code easier to debug.
9515 The functional style also makes code easier to read and maintain.
9516 * systime.h: Include <sys/time.h> on all hosts, not just if
9517 WINDOWSNT, since 'struct timeval' is needed in general.
9518 (EMACS_TIME): Now a typedef, not a macro.
9519 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9520 not macros.

9530 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9531 not functions. All uses rewritten to use the following, respectively:
9532 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9533 (add_emacs_time, sub_emacs_time): New functions.
9534 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9535 * fileio.c (Fcopy_file):
9536 * xterm.c (XTflash): Get the current time closer to when it's used.
9537 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9547 * nsmenu.m (ns_update_menubar):
9548 * regex.c (regerror):
9549 Prefer memcpy to strncpy and strncat when either will do.
9550 * fileio.c (Fsubstitute_in_file_name):
9551 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9552 (menu_separator_name_p):
9553 * nsmenu.m (ns_update_menubar):
9554 Prefer memcmp to strncmp when either will do.
9555 * nsterm.m: Include <ftoastr.h>.
9556 (ns_get_color):
9557 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9558 Prefer snprintf to strncpy.
9559 * nsterm.m (ns_term_init):
9560 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9561 * nsterm.m (ns_term_init):
9562 Avoid the need for strncpy, by using build_string or
9563 make_unibyte_string directly. Use dtoastr, not snprintf.
9564 * process.c (Fmake_network_process): Diagnose service names that
9565 are too long, rather than silently truncating them or creating
9566 non-null-terminated names.

9568 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9569 Prefer sprintf to strncat.
9570 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

9582 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9583 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9584 where argument type is known to be a Lisp_Cons.

9595
9596 Optimize pure C strings initialization.
9597 * lisp.h (make_pure_string): Fix prototype.

9599 provides a better opportunity to optimize away calls to strlen when
9600 the function is called with compile-time constant argument.
9601 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9602 argument, adjust users accordingly. Use build_pure_c_string where
9603 appropriate.
9604 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9605 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9606 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

9640
9641 Stop ns builds setting the EMACSLOADPATH environment variable.
9642 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9643 Now it does not set EMACSLOADPATH, just returns the load-path string.

9715
9716 Move marker debugging code under MARKER_DEBUG.
9717 * marker.c (MARKER_DEBUG): Move marker debugging code under
9718 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9719 for bootstrap with --enable-checking (~3x slowdown reported
9720 by Juanma Barranquero <lekktu@gmail.com>).
9721 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9722

9774 (init_lread): Reorganize. Motivation:
9775 If EMACSLOADPATH is set, check/warn about that rather than the
9776 defaults, which we are not going to use. Hence we can remove
9777 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9778 Don't warn if site-lisp directories are missing.
9779 If not installed, start from a blank load-path, since
9780 PATH_LOADSEARCH refers to the eventual installation directories.

9783
9784 Support truncation and continuation glyphs on GUI frames, when
9785 fringes are disabled. (Bug#11832)
9786 * xdisp.c (init_iterator): Get dimensions of truncation and
9787 continuation glyphs even if on GUI frames.
9788 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9789 or both, are absent.
9790 (start_display, move_it_in_display_line_to): Handle the case of a
9791 GUI frame without a fringe to display continuation or truncation
9792 glyphs.
9793 (insert_left_trunc_glyphs): Support GUI frames: make sure
9794 truncation glyphs overwrite enough glyphs from the current line to
9795 have sufficient space in pixels.
9796 (display_line): Support truncation and continuation glyphs on GUI
9797 frames. If some spare pixels are left on the line after inserting
9798 the truncation glyphs, fill that space with a stretch glyph of a
9799 suitably computed width.
9800
9801 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9802 produce_glyphs, to support GUI sessions.
9803
9804 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9805
9806 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9807
9808 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9809
9810 Do not require float-time's arg to fit in time_t (Bug#11825).
9811 This works better on hosts where time_t is unsigned, and where
9812 float-time is applied to the (negative) difference between two times.
9813 * editfns.c (decode_time_components): Last arg is now double *,
9814 not int *, and means to store all the result as a double, without
9815 worrying about whether the seconds part fits in time_t.
9816 All callers changed.
9817 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9818 All callers changed.
9819 (Ffloat_time): Do not fail merely because the specified time falls
9820 outside of time_t range.
9821
9822 2012-07-07 Glenn Morris <rgm@gnu.org>
9823
9824 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9827
9828 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9829
9830 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9831 Update dependencies.
9832
9833 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9834
9835 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9836
9837 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9838 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9839 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9840 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9841 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9842 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9843
9844 * xfont.c (compare_font_names): Redo to omit the need for casts.
9845
9846 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9847
9848 * xfns.c (Fx_change_window_property): Doc fix.
9849 * w32fns.c (Fx_change_window_property): Doc fix.
9850
9851 * w32fns.c (Fx_window_property): Accept the same arguments as the
9852 X Windows version. Doc fix.
9853 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9854
9855 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9856 Eli Zaretskii <eliz@gnu.org>
9857
9858 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9859 Windows-specific code from nt/config.nt moved here.
9860 Obsolete settings removed.
9861
9862 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9863
9864 * process.c: Avoid unnecessary calls to gettime.
9865 (wait_reading_process_output): Don't get the time of day
9866 when gobbling data immediately and not waiting, as there's no need
9867 for it in that case. This removes a FIXME.
9868
9869 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9870
9871 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9872 is defined (Bug#11768).
9873
9874 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9875
9876 Fix marker debugging code.
9877 * marker.c (byte_char_debug_check): Do not perform the check
9878 if buffer is not multibyte.
9879 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9880 Call byte_char_debug_check with correct arguments.
9881
9882 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9883
9884 Compile marker debugging code only if ENABLE_CHECKING is defined.
9885 * marker.c (byte_char_debug_check, count_markers):
9886 Use only if ENABLE_CHECKING is defined.
9887 (byte_debug_flag): Remove.
9888 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9889 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9890
9891 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9892
9893 Avoid code repetition in marker-related functions.
9894 * marker.c (attach_marker): New function.
9895 (Fset_marker, set_marker_restricted, set_marker_both)
9896 (set_marker_restricted_both): Use it.
9897 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9898 Consistently rename charno to charpos.
9899 (marker_position): Add eassert.
9900 (marker_byte_position): Convert to eassert.
9901
9902 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9903
9904 Simplify list operations in unchain_overlay and unchain_marker.

9907
9908 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9909
9910 Introduce fast path for the widely used marker operation.
9911 * alloc.c (build_marker): New function.
9912 * lisp.h (build_marker): New prototype.
9913 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9914 * composite.c (autocmp_chars): Likewise.
9915 * editfns.c (buildmark): Remove.
9916 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9917 (save_restriction_save): Use build_marker.
9918 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9919 * window.c (save_window_save): Likewise.
9920

9926 (delete_all_overlays, Fdelete_overlay): Use it.
9927 * minibuf.c (get_minibuffer): Fix comment.
9928
9929 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9930
9931 Port to OpenBSD 5.1 amd64.
9932 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9933 This is needed for OpenBSD, and should be harmless on all BSD systems.
9934 Also, include <sys/sysctl.h>, as it should be available on all
9935 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9936 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9937 use p_pid member, not kp_proc.pid.
9938
9939 2012-07-06 Glenn Morris <rgm@gnu.org>
9940
9941 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9942
9943 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9944

9954 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9955 * xterm.c:
9956 Omit needless casts involving void * pointers and allocation.
9957 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9958 as the former is more robust if P's type is changed.
9959 Prefer xzalloc to xmalloc + memset 0.
9960 Simplify malloc-or-realloc to realloc.
9961 Don't worry about xmalloc returning a null pointer.
9962 Prefer xstrdup to xmalloc + strcpy.
9963 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9964 growing it.
9965 * keyboard.c (apply_modifiers_uncached): Prefer local array to

9968 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9969
9970 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9971 hscroll is larger than the line width. Fixes long and futile
9972 looping inside extend_face_to_end_of_line (on a TTY) producing
9973 glyphs that are not needed and thrown away.
9974
9975 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9976
9977 * marker.c (set_marker_restricted_both): Simplify by using

9986 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9987 not defined (Bug#11768).
9988 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9989 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9990 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9991 followed by gtk_box_set_homogeneous (Bug#11768).
9992 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9993 (update_theme_scrollbar_width, xg_create_scroll_bar):
9994 Use gtk_scrollbar_new (Bug#11768).
9995 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9996 (is_box_type): New function (Bug#11768).
9997 (xg_tool_item_stale_p): Call is_box_type.
9998 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9999 with default display (Bug#11768).

10001 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10002
10003 * xdisp.c (window_hscroll_limited): New function.
10004 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10005 coordinates when window's hscroll is set to insanely large
10006 values. (Bug#11857)
10007
10008 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10070
10071 * fileio.c (time_error_value): Check the right error number.
10072 Problem reported by Troels Nielsen in
10073 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10074
10075 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10076
10077 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10078 This should be fixed in a better way; see Eli Zaretskii in
10079 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10080 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10081
10082 * fileio.c (time_error_value): Rename from special_mtime.
10083 The old name's problems were noted by Eli Zaretskii in
10084 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10085
10086 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10087 This variable's comment says Emacs needs at least one GDB-visible
10088 symbol of type enum pvec_type, to work around GDB problems.
10089 The symbol's value doesn't matter.
10090
10091 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10092 that causes compilation to fail on pre-C99 compilers.
10093

10099 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10100
10101 * buffer.c (init_buffer_once): Fix initialization of

10103 Reported by Juanma Barranquero <lekktu@gmail.com>.
10104
10105 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10106
10107 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10108 * lisp.h (enum pvec_type): Use fewer bits.
10109 (PSEUDOVECTOR_SIZE_BITS): New constant.
10110 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10111 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10112 change in pvec_type.
10113 (PSEUDOVECTOR_TYPEP): New macro.
10114 (TYPED_PSEUDOVECTORP): Use it.
10115 * fns.c (internal_equal): Adapt code to extract pvectype.
10116 * emacs.c (gdb_pvec_type): Update type.
10117 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.

10119 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10120 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10121 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10122 abusing vector->header.next.nbytes.
10123 (live_vector_p): Use PVEC_TYPE.
10124 (mark_object): Adapt code to extract pvectype. Use switch.
10125
10126 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10127
10128 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10129 Tighten new eassert a bit.
10130
10131 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10132
10133 Fix compilation with --enable-gcc-warnings and -O1
10134 optimization level.
10135 * doprnt.c (doprnt): Change type of tem to int, initialize
10136 to avoid compiler warning. Add eassert.
10137 * search.c (simple_search): Initialize match_byte to avoid
10138 compiler warning. Add eassert.
10139
10140 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10141
10142 Avoid weird behavior with large horizontal scrolls.
10143 Without this change, for example, large hscroll values would
10144 mess up Emacs's display on Fedora 15 x86, presumably due to
10145 overflows in int calculations in the display code.
10146 Also, if buffers had long lines, Emacs would freeze.
10147 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10148 (set_window_hscroll): New function, containing the old guts of
10149 Fset_window_hscroll. Return the clipped value.
10150 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10151 This avoids the need to check against PTRDIFF_MAX.
10152
10153 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10154
10155 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

10158
10159 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10160
10161 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10162 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10163 since GCC 4.4.6 issues a bogus warning for them.
10164
10165 Fix bugs in file timestamp newness comparisons.
10166 * fileio.c (Ffile_newer_than_file_p):
10167 * lread.c (Fload): Use full timestamp resolution of files,
10168 not just the 1-second resolution, so that files that are only
10169 slightly newer still count as newer.
10170 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10171 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10172
10173 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10174
10175 * fileio.c: Improve handling of file time marker. (Bug#11852)
10176 (special_mtime): New function.
10177 (Finsert_file_contents, Fverify_visited_file_modtime):

10186
10187 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10188 and did not make it into globals.h).
10189
10190 2012-07-03 Tom Tromey <tromey@redhat.com>
10191
10192 * window.c (Fset_window_margins, Fset_window_fringes)

10230 * lisp.h (Frandom): Make it visible to C.
10231 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new

10235
10236 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10237 values which aren't power of 2.
10238 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10239 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10240 accordingly.
10241
10242 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10243
10244 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10245
10246 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10247
10248 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10249
10250 * alloc.c (allocate_vector_block): Remove redundant
10251 calls to mallopt if DOUG_LEA_MALLOC is defined.

10254
10255 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10256
10257 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES

10259 running undumped.
10260
10261 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10262
10263 Cleanup basic buffer management.
10264 * buffer.h (struct buffer): Change layout to use generic vector
10265 marking code. Fix some comments. Change type of 'clip_changed'
10266 to bitfield. Remove unused #ifndef old.
10267 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

10280
10281 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10282
10283 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10284 wrapper that is not needed because the wrapped code is a no-op (zero
10285 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10286 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10287
10288 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10289
10290 * alloc.c (mark_buffer): Simplify. Remove prototype.
10291 (mark_object): Add comment. Reorganize marking of vector-like
10292 objects. Use CHECK_LIVE for all vector-like objects except buffers
10293 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10294 Avoid redundant calls to mark_vectorlike for bool vectors.
10295
10296 2012-06-30 Glenn Morris <rgm@gnu.org>
10297
10298 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10299
10300 * epaths.in (PATH_SITELOADSEARCH): New.
10301 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10302 This is rather than relying on --enable-locallisppath elements
10303 having "site-lisp" in their names. (Bug#10208#25, 11658)
10304
10305 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10306

10309 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10310
10311 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10312 (pselect) [!MS_DOS]: Redirect to sys_select.
10313
10314 * sysdep.c: Don't include dos.h and dosfns.h.
10315
10316 * process.c (sys_select):
10317 * msdos.c (sys_select): Accept one more argument and ignore it.
10318
10319 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10320 adapt data types and code to that.
10321
10322 * dosfns.c:
10323 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10324 which clashes with the gnulib function of the same name.
10325
10326 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10327
10328 * font.c (font_style_to_value, font_style_symbolic)
10329 (font_prop_validate_style): Add type checks for values in
10330 font_style_table.
10331
10332 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10333 argument.
10334 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10335 uses.
10336
10337 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10338
10339 * xdisp.c (try_window_id): Undo last change.
10340
10341 * w32.c (getwd): Adjust commentary about startup_dir.
10342 (init_environment): Always call sys_access, even in non-MSVC
10343 builds. Don't chdir to the directory of the Emacs executable.
10344 This undoes code from 1997 which was justified by the need to
10345 "avoid conflicts when removing and renaming directories". But its
10346 downside was that every relative file name was being interpreted
10347 relative to the directory of the Emacs executable, which can never
10348 be TRT. In particular, it broke sys_access when called with
10349 relative file names.
10350 (sys_access): Map GetLastError to errno.
10351
10352 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10353
10354 * window.h (struct window): Change type of 'fringes_outside_margins'
10355 to bitfield. Fix comment. Adjust users accordingly.
10356 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10357 Adjust comment.
10358 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10359 to ptrdiff_t.

10379 * nsterm.m: Likewise.

10390 overflow when requested scroll falls outside ptrdiff_t range.
10391
10392 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10393
10394 * window.h (struct window): Change type of 'hscroll',
10395 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10396 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10397 Adjust users accordingly.
10398 * xdisp.c (try_cursor_movement): Replace type check with eassert.

10420 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10421 adjust comments accordingly.

10497 2012-06-26 John Wiegley <johnw@newartisans.com>
10498
10499 * unexmacosx.c (copy_data_segment): Add two section names used
10500 on Mac OS X Lion: __mod_init_func and __mod_term_func.
10501
10502 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10503 when building with Clang.

10535 * lisp.h: Define build_string as static inline. This provides

10543
10544 Use sprintf return value instead of invoking strlen on result.
10545 In the old days this wasn't portable, since some sprintf
10546 implementations returned char *. But they died out years ago and
10547 Emacs already assumes sprintf returns int.
10548 Similarly for float_to_string.
10549 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10550 * ccl.c (ccl_driver):
10551 * character.c (string_escape_byte8):

10554 * print.c (print_object):
10555 * xdisp.c (message_dolog):
10556 * xfns.c (syms_of_xfns):
10557 Use sprintf or float_to_string result to avoid need to call strlen.
10558 * data.c (Fnumber_to_string):
10559 Use make_unibyte_string, since the string must be ASCII.
10560 * lisp.h, print.c (float_to_string): Now returns int length.
10561 * term.c (produce_glyphless_glyph):
10562 Use sprintf result rather than recomputing it.
10563
10564 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10565 * Makefile.in (ALL_CFLAGS):
10566 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10567 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10568
10569 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10570

10579 * menu.c (push_submenu_start, push_submenu_end)
10580 (push_left_right_boundary, push_menu_pane): Likewise.

10589
10590 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10591 sprintf already null-terminates its output.
10592
10593 * xfns.c (x_window): Remove redundant cast.
10594
10595 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10596
10597 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10598 `const char *' to `char *' to avoid compiler warning.
10599
10600 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10601
10602 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10603 instead of truncating it to 63 (admittedly a generous limit).
10604
10605 * process.c: Fix spelling and caps in comments.

10662 * dispnew.c (Fsleep_for, sit_for):
10663 * keyboard.c (kbd_buffer_get_event):
10664 * process.c (Faccept_process_output):
10665 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10666 This improves on the previous patch, which introduced a bug
10667 when time_t is unsigned and as wide as intmax_t.
10668 See <http://bugs.gnu.org/9000#51>.

10687 Privately reported by Herbert J. Skuhra.
10688 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10689 All uses changed.
10690 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10691 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10692
10693 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10733 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10734
10735 Support higher-resolution time stamps (Bug#9000).
10736 The time stamps are only nanosecond-resolution at the C level,
10737 since that's the best that any real-world system supports now.
10738 But they are picosecond-resolution at the Lisp level, as that's
10739 easy, and leaves room for future OS improvements.
10740
10741 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10742 (LIBES): Use it.
10743
10744 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10745 Don't get current time unless it's needed.
10746
10747 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10748 now provides it if it's absent.
10749 (start_atimer): Port to higher-res time stamps.
10750 Check for time stamp overflow. Don't get current time more
10751 often than is needed.
10752
10753 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10754 Include systime.h, not time.h.
10755 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10756
10757 * dired.c: Include stat-time.h.
10758 (Ffile-attributes): File times now have higher resolution.
10759
10760 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10761 (struct image): Timestamp now has higher resolution.
10762
10763 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10764 has at least microseconds now. All uses removed.
10765 (update_frame, update_single_window, update_window, update_frame_1)
10766 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10767 (duration_to_sec_usec): Remove; no longer needed.
10768

10771 (float-time, Fformat_time_string, Fcurrent_time_string)
10772 (Fcurrent_time_zone): Accept and generate higher-resolution
10773 time stamps.
10774 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10775 (decode_time_components, lisp_seconds_argument): New functions.
10776 (make_time): Now static.
10777 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10778 Report an error if the time is invalid, rather than having the caller
10779 do that.
10780
10781 * fileio.c: Include <stat-time.h>
10782 (Fcopy_file): Copy higher-resolution time stamps.
10783 Prefer to set the time stamp via a file descriptor if that works.
10784 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10785 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10786 (Fvisited_file_modtime, Fset_visited_file_modtime):
10787 Support higher-resolution time stamps.
10788
10789 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10790
10791 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10792
10793 * image.c (prepare_image_for_display, clear_image_cache)
10794 (lookup_image): Port to higer-resolution time stamps.
10795
10796 * keyboard.c (start_polling, bind_polling_period):
10797 Check for time stamp overflow.
10798 (read_char, kbd_buffer_get_event, timer_start_idle)
10799 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10800 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10801 Port to higher-resolution time stamps. Do not assume time_t is signed.
10802 (decode_timer): New function. Timers are now vectors of length 9,
10803 not 8, to accommodate the picosecond component.
10804 (timer_check_2): Use it.
10805
10806 * nsterm.m (select_timeout, timeval_subtract): Remove.
10807 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10808 as they're a bit more accurate and handle overflow better.
10809 (ns_select): Change prototype to be compatible with pselect.
10810 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10811 * nsterm.h (ns_select): Adjust prototype.
10812
10813 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10814 us-resolution time stamps.
10815 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10816
10817 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10818
10819 * lisp.h (time_overflow): New decl.
10820 (wait_reading_process_output): First arg is now intmax_t, not int,
10821 to accommodate larger waits.
10822
10823 * process.h (struct Lisp_Process.read_output_delay):
10824 Now counts nanoseconds, not microseconds.
10825 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10826 EMACS_HAS_USECS.
10827 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10828 (wait_reading_process_output):
10829 Port to ns-resolution time stamps.
10830 (Faccept_process_output, wait_reading_process_output):
10831 Check for time stamp overflow. Do not assume time_t is signed.
10832 (select_wrapper): Remove; we now use pselect.
10833 (Fprocess_attributes): Now generates ns-resolution time stamps.
10834
10835 * sysdep.c: Include utimens.h. Don't include utime.h
10836 or worry about struct utimbuf; gnulib does that for us now.
10837 (gettimeofday): Remove; gnulib provides a substitute.
10838 (make_timeval): New function.
10839 (set_file_times): Now sets ns-resolution time stamps.
10840 New arg FD; all uses changed.
10841 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10842 (system_process_attributes):
10843 Now returns ns-resolution time stamp. All uses changed.
10844 Check for time stamp overflow.
10845
10846 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10847 provides a substitute now.
10848
10849 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10850 since it guarantees struct timespec.
10851 (EMACS_TIME): Now struct timespec, so that we can support
10852 ns-resolution time stamps.
10853 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10854 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10855 (EMACS_USECS): Remove.
10856 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10857 so multiply the arg by 1000 before storing it.
10858 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10859 New macros.
10860 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10861 Port to ns-resolution time stamps.
10862 (EMACS_TIME_NEG_P): Remove; replaced by....
10863 (EMACS_TIME_SIGN): New macro.
10864 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10865 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10866 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10867 (make_timeval, make_lisp_time, decode_time_components): New decls.
10868 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10869 that it mishandled time_t overflow. You can't compare by subtracting!
10870 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10871 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10872
10873 * term.c: Include <sys/time.h>.
10874 (timeval_to_Time): New function, for proper overflow wraparound.
10875 (term_mouse_position, term_mouse_click): Use it.
10876
10877 * undo.c (record_first_change): Support higher-resolution time stamps
10878 in the undo buffer.
10879 (Fprimitive_undo): Use them when restoring time stamps.
10880
10881 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10882 (w32_get_internal_run_time):
10883 Port to higher-resolution Emacs time stamps.
10884 (ltime): Now accepts single 64-bit integer, as that's more convenient
10885 for callers.
10886
10887 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10888
10889 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10890 for compatibility with pselect. Support ns-resolution time stamps.
10891
10892 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10893
10894 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10895 Check for time stamp overflow, and support ns-resolution time stamps.
10896
10897 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10898 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10899 (timeval_subtract): Remove; no longer needed.
10900 (XTflash, XTring_bell, x_wait_for_event):
10901 Port to ns-resolution time stamps. Don't assume time_t is signed.
10902

10906
10907 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10908
10909 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10910 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10911 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10912 staticidx goes up to 1597 out of 1600 = 0x640.)
10913
10914 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10915
10916 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10917 Otherwise, the umask might be mistakenly 0 while handling input signals.
10918
10919 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10920
10921 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
10922
10923 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
10924
10925 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
10926 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
10927 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10928 access to `contents' member of Lisp_Vector objects with AREF and ASET
10929 where appropriate.
10930
10931 2012-06-19 Chong Yidong <cyd@gnu.org>
10932

10937 frame's selected window and its terminal's top-frame.
10938 (unwind_format_mode_line): Restore them.
10939 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10940 Callers changed.
10941 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10942 since tty frames can be explicitly named.
10943 (prepare_menu_bars): Likewise.
10944
10945 * term.c (Ftty_top_frame): New function.
10946
10947 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10948
10949 Port byte-code-meter to modern targets.
10950 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10951 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10952 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10953 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10954 (METER_1, METER_2): Simplify.
10955
10956 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10957
10958 * data.c (Fdefalias): Return `symbol' (bug#11686).
10959
10960 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10961
10962 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10963 gets killed during executing of this function (Bug#11665).
10964 Try to always return Qt when the buffer has been actually killed.
10965 (Vkill_buffer_query_functions): In doc-string say that functions
10966 run by this hook should not change the current buffer.
10967
10968 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10969
10970 Fix recently-introduced process.c problems found by static checking.
10971 * process.c (write_queue_push, write_queue_pop, send_process):
10972 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
10973 (write_queue_pop): Fix pointer signedness problem.
10974 (send_process): Remove unused local.
10975
10976 2012-06-17 Chong Yidong <cyd@gnu.org>
10977
10978 * xdisp.c (redisplay_internal): No need to redisplay terminal
10979 frames that are not on top.

10981 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
10982
10983 * process.c (make_process): Initialize write_queue.
10984 (write_queue_push, write_queue_pop): New functions.

10986 writes (Bug#10815).
10987
10988 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10989
10990 * lisp.h (eassert): Assume C89 or later.
10991 This removes the need for CHECK.
10992 (CHECK): Remove. Its comments about always evaluating its
10993 argument were confusing, as 'eassert' typically does not evaluate
10994 its argument.
10995
10996 * coding.c (produce_chars): Use ptrdiff_t, not int.

11091
11092 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
11093 If all the glyphs of the glyph row came from strings, and we have no
11094 cursor positioning clues, put the cursor on the first glyph of the
11095 row.
11096 (handle_face_prop): Use chunk-relative overlay string index when
11097 indexing into it->string_overlays array. (Bug#11653)

11181 USE_LSB_TAG now is always defined to be either 0 or 1.
11182 All uses changed.
11183 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11184 code works fine either way, and efficiency is not a concern here,
11185 as the union type is for debugging, not for production.
11186 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11187 Use an inline function on all platforms when using the union type,
11188 since this is simpler and 'static inline' can be used portably
11189 within Emacs now.
11190 (LISP_INITIALLY_ZERO): New macro.
11191 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11192 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11274 * xdisp.c (vmessage): Treat frame message as multibyte.
11275 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
11276 would generate the diagnostic "Making \302\247 buffer-local while
11277 let-bound!".
11278

11333 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11334 would mishandle a string argument "Xc" if X was a multibyte
11335 character of length 2: it would truncate after X's first byte
11336 rather than including all of X.

11399
11400 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11401
11402 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11403
11404 For a 'struct window', replace some Lisp_Object fields to
11405 bitfields where appropriate, remove unused fields.
11406 * window.h (struct window): Remove unused 'last_mark_x' and
11407 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11408 change its type from Lisp_Object to bitfield.
11409 Change type of 'force_start', 'optional_new_start',
11410 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11411 fields from Lisp_Object to bitfield. Adjust users accordingly.
11412
11413 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11414
11415 Pacify gcc -Wdouble-precision when using Xaw.
11416 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11417 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11418 Use 'float' consistently, rather than 'float' in most places
11419 and 'double' in a couple of places.
11420
11421 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11422
11423 * xdisp.c (handle_stop): Detect whether we have overlay strings
11424 loaded by testing it->current.overlay_string_index to be
11425 non-negative, instead of checking whether n_overlay_strings is
11426 positive. (Bug#11587)
11427
11428 2012-05-31 Chong Yidong <cyd@gnu.org>
11429
11430 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11431
11432 * doc.c (Fsubstitute_command_keys): Doc fix.
11433
11434 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11435
11436 * search.c (search_buffer): Remove calls to
11437 r_alloc_inhibit_buffer_relocation, as it is now called by
11438 maybe_unify_char, which was the cause of relocation of buffer text
11439 in bug#11519.
11440
11441 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11442
11443 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11444 for the duration of call to load_charset, to avoid problems with
11445 callers of maybe_unify_char that access buffer text through C
11446 pointers.
11447
11448 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11449 decrement the inhibition flag, instead of just setting or
11450 resetting it.
11451
11452 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11453
11454 Remove obsolete '#define static' cruft.
11455 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11456 This #undef was "temporary" in 2000; it is no longer needed
11457 now that '#define static' has gone away.
11458 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11459 (gray_bitmap_bits): Remove; no longer needed.
11460 All uses replaced with definiens.
11461 * xterm.c: Include "bitmaps/gray.xbm".
11462
11463 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11464
11465 Clean up __executable_start, monstartup when --enable-profiling.
11466 The following changes affect the code only when profiling.
11467 * dispnew.c (__executable_start): Rename from safe_bcopy.
11468 Define only on platforms that need it.
11469 * emacs.c: Include <sys/gmon.h> when profiling.
11470 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11471 (__executable_start): Remove decl, since lisp.h does it now.
11472 (safe_bcopy): Remove decl; no longer has that name.
11473 (main): Coalesce #if into single bit of code, for simplicity.
11474 Cast pointers to uintptr_t, since standard libraries want integers
11475 and not pointers.
11476 * lisp.h (__executable_start): New decl.
11477
11478 2012-05-31 Glenn Morris <rgm@gnu.org>
11479
11480 * image.c (Fimagemagick_types): Doc fix.
11481
11482 2012-05-30 Jim Meyering <meyering@redhat.com>
11483
11484 * callproc.c (Fcall_process_region): Include directory component
11485 in mkstemp error message (Bug#11586).
11486
11487 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11488
11489 * alloc.c, lisp.h (make_pure_vector): Now static.
11490
11491 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
11492
11493 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
11494 Move to byte-run.el.
11495 (Fautoload): Do the hash-doc more carefully.
11496 * data.c (Fdefalias): Purify definition, except for keymaps.
11497 (Qdefun): Move from eval.c.
11498 * lisp.h (Qdefun): Remove.
11499 * lread.c (read1): Tiny simplification.
11500
11501 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11502
11503 Do not create empty overlays with the evaporate property (Bug#9642).
11504 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11505 Bug#9642, but explicitly check that the buffer the overlay would
11506 be moved to is live and rearrange lines to make sure that errors
11507 will not put the overlay in an inconsistent state.
11508 (Fdelete_overlay): Cosmetics.
11509
11510 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11511
11512 * w32term.c (my_bring_window_to_top): New function.
11513 (x_raise_frame): Use handle returned by DeferWindowPos, which
11514 could be different from the original one.
11515 Call my_bring_window_to_top instead of my_set_foreground_window.
11516 (Bug#11513)
11517
11518 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11519 by calling BringWindowToTop.
11520
11521 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
11522 (WM_EMACS_END): Increase by one.
11523
11524 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11525
11526 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11527 This avoids undefined behavior that might cause the eassert
11528 to not catch an out-of-range value.
11529
11530 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11531
11532 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11533 Update dependencies.
11534
11535 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11536
11537 * bidi.c (bidi_mirror_char): Fix last change.
11538
11539 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11540
11541 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11542 when referring to sectname field in printf format.
11543
11544 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11545
11546 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11547 Only r_alloc_inhibit_buffer_relocation needed to be added;
11548 the others were already declared.
11549
11550 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11551 before checking whether it's out of range. Put the check inside
11552 eassert. See
11553 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11554
11555 2012-05-27 Ken Brown <kbrown@cornell.edu>
11556
11557 * callproc.c (Fcall_process): Restore a line that was accidentally
11558 commented out in the 2011-02-13 change (bug#11547).
11559
11560 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11561
11562 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11563 defined on ralloc.c.
11564
11565 * buffer.c [REL_ALLOC]: Remove prototypes of
11566 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11567 they are now on lisp.h.
11568
11569 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11570
11571 * search.c (search_buffer): Use it to inhibit relocation of buffer
11572 text while re_search_2 is doing its job, because re_search_2 is
11573 passed C pointers to buffer text. (Bug#11519)
11574
11575 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11576 Update value to 24.
11577
11578 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11579 state after an additional call to move_it_in_display_line_to, keep
11580 the values of it->max_ascent and it->max_descent found for the
11581 entire line.
11582 (pos_visible_p): Revert the comparison against bottom_y to what it
11583 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11584 (Bug#11464)
11585
11586 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11587
11588 Fix coding-related core dumps with gcc -ftrapv.
11589 The code was computing A - B, where A and B are pointers, and B is
11590 random garbage. This can lead to core dumps on platforms that
11591 have special pointer registers, and it also leads to core dumps on
11592 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11593 A - B only when B is initialized properly.
11594 * coding.c (coding_set_source, coding_set_destination): Return void.
11595 (coding_change_source, coding_change_destinations): New functions,
11596 with the old behaviors of coding_set_source and coding_set_destination.
11597 All callers that need an offset changed to use these new functions.
11598
11599 2012-05-26 Glenn Morris <rgm@gnu.org>
11600
11601 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11602
11603 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11604
11605 Extend mouse support on W32 text-mode console.
11606 * xdisp.c (draw_row_with_mouse_face):
11607 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11608
11609 * w32console.c: Include window.h.
11610 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11611 New functions.
11612 (initialize_w32_display): Initialize mouse-highlight data.
11613
11614 * w32inevt.c: Include termchar.h and window.h.
11615 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11616 moves, call note_mouse_highlight. If help_echo changed, call
11617 gen_help_event to produce help-echo message in the echo area.
11618 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11619 highlight info.
11620
11621 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11622
11623 * lread.c (read1): Simplify slightly to avoid an overflow warning
11624 with GCC 4.7.0 on x86-64.
11625
11626 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11627
11628 * bidi.c (bidi_mirror_char): Revert last change: an int is
11629 definitely wide enough here.
11630
11631 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11632
11633 Fix integer width and related bugs (Bug#9874).
11634 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11635 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11636 (string_bytes, check_sblock, allocate_string_data):
11637 (compact_small_strings, Fmake_bool_vector, make_string)
11638 (make_unibyte_string, make_multibyte_string)
11639 (make_string_from_bytes, make_specified_string)
11640 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11641 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11642 (mark_vectorlike):
11643 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11644 (allocate_pseudovector):
11645 Use int, not EMACS_INT, where int is wide enough.
11646 (inhibit_garbage_collection, Fgarbage_collect):
11647 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11648 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11649 int might not be wide enough.
11650 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11651 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11652 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11653 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11654 (bidi_level_of_next_char, bidi_move_to_visually_next):
11655 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11656 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11657 (Fkill_buffer, Fset_buffer_major_mode)
11658 (advance_to_char_boundary, Fbuffer_swap_text)
11659 (Fset_buffer_multibyte, overlays_at, overlays_in)
11660 (overlay_touches_p, struct sortvec, record_overlay_string)
11661 (overlay_strings, recenter_overlay_lists)
11662 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11663 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11664 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11665 (Foverlay_recenter, last_overlay_modification_hooks_used)
11666 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11667 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11668 (validate_region): Omit unnecessary test for b <= e,
11669 since that's guaranteed by the previous test.
11670 (adjust_overlays_for_delete): Avoid pos + length overflow.
11671 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11672 (report_overlay_modification):
11673 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11674 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11675 Omit pointer cast, which isn't needed anyway, and doesn't work
11676 after the EMACS_INT -> ptrdiff_t change.
11677 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11678 * buffer.h: Adjust decls to match defn changes elsewhere.
11679 (struct buffer_text, struct buffer):
11680 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11681 Use EMACS_INT, not int, where int might not be wide enough.
11682 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11683 not int, to avoid needless 32-bit limit on 64-bit hosts.
11684 (exec_byte_code): Use tighter memory-full test, one that checks
11685 for alloca overflow. Don't compute the address of the object just
11686 before an array, as that's not portable. Use EMACS_INT, not
11687 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11688 * callint.c (Fcall_interactively):
11689 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11690 * callproc.c (call_process_kill, Fcall_process):
11691 Don't assume pid_t fits into an Emacs fixnum.
11692 (call_process_cleanup, Fcall_process, child_setup):
11693 Don't assume pid_t fits into int.
11694 (call_process_cleanup, Fcall_process, delete_temp_file)
11695 (Fcall_process_region):
11696 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11697 (Fcall_process): Simplify handling of volatile integers.
11698 Use int, not EMACS_INT, where int will do.
11699 * casefiddle.c (casify_object, casify_region, operate_on_word)
11700 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11701 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11702 (casify_object): Avoid integer overflow when overallocating buffer.
11703 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11704 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11705 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11706 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11707 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11708 integers are now checked earlier. All uses replaced with XINT.
11709 (ccl_driver):
11710 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11711 For CCL_MapSingle, check that content and value are in int range.
11712 (ccl_driver, Fregister_code_conversion_map):
11713 Check that Vcode_version_map_vector is a vector.
11714 (resolve_symbol_ccl_program): Check that vector header is in range.
11715 Always copy the vector, so that we can check its contents reliably
11716 now rather than having to recheck each instruction as it's being
11717 executed. Check that vector words fit in 'int'.
11718 (ccl_get_compiled_code, Fregister_ccl_program)
11719 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11720 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11721 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11722 contents are in range.
11723 (Fccl_execute_on_string): Check that status is in range.
11724 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11725 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11726 Accept and return EMACS_INT, not int, because callers can pass values
11727 out of 'int' range.
11728 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11729 (multibyte_chars_in_text, parse_str_as_multibyte)
11730 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11731 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11732 (string_escape_byte8, Fget_byte):
11733 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11734 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11735 avoid mishandling large integers.
11736 * character.h: Adjust decls to match defn changes elsewhere.
11737 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11738 (Ffind_charset_region):
11739 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11740 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11741 (load_charset_map_from_vector, Fdefine_charset_internal):
11742 Don't assume fixnum fits in int.
11743 (load_charset_map_from_vector, Fmap_charset_chars):
11744 Remove now-unnecessary CHECK_NATNUMs.
11745 (Fdefine_charset_internal): Check ranges here, more carefully.
11746 Don't rely on undefined behavior with signed left shift overflow.
11747 Don't assume unsigned int fits into fixnum, or that fixnum fits
11748 into unsigned int. Don't require max_code to be a valid fixnum;
11749 that's not true for gb10830 4-byte on a 32-bit host. Allow
11750 invalid_code to be a cons, for the same reason. Require code_offset
11751 to be a character. Avoid int overflow if max_char is close
11752 to INT_MAX.
11753 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11754 this is intended anyway and avoids some undefined behavior.
11755 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11756 INDEX_TO_CODE_POINT, as that's what it expects.
11757 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11758 * charset.h (DECODE_CHAR): Return int, not unsigned;
11759 this is what was intended anyway, and it avoids undefined behavior.
11760 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11761 integer-overflow issues.
11762 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11763 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11764 where the argument is EMACS_INT, and this behavior is not intended.
11765 * chartab.c (Fmake_char_table, Fset_char_table_range)
11766 (uniprop_get_decoder, uniprop_get_encoder):
11767 Don't assume fixnum fits in int.
11768 * cmds.c (move_point): New function, that does the gist of
11769 Fforward_char and Fbackward_char, but does so while checking

12428 * xterm.h: Adjust decls to match defn changes elsewhere.
12429 (struct scroll_bar): Use struct vectorlike_header
12430 rather than rolling our own approximation.
12431 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12432
12433 2012-05-25 Glenn Morris <rgm@gnu.org>
12434
12435 * lisp.mk (lisp): Update for more files being compiled now.
12436
12437 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12438
12439 * lread.c: Remove `read_pure' which makes no difference.
12440 (read_pure): Remove var.
12441 (unreadpure): Remove function.
12442 (readevalloop): Don't call read_list with -1 flag.
12443 (read1, read_vector): Don't test read_pure any more.
12444 (read_list): Simplify.
12445
12446 * fileio.c, character.h: Minor style tweaks.
12447
12448 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12449
12450 * window.h (clip_changed): Remove useless declaration.
12451
12452 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12453
12454 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12455 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12456
12457 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12458
12459 Remove src/m/*.
12460 This directory predates autoconf and is no longer needed nowadays.
12461 Move its few remaining bits of functionality to where they're needed.
12462 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12463 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12464 * m/template.h: Remove.
12465 * Makefile.in (M_FILE): Remove. All uses removed.
12466 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12467 * lisp.h (USE_LSB_TAG):
12468 * mem-limits.h (EXCEEDS_LISP_PTR):
12469 Use VAL_MAX, not VALBITS, in #if.
12470 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12471 (EMACS_UINT): Define unconditionally now.
12472 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12473 (BITS_PER_EMACS_INT): New constants, replacing
12474 what used to be in config.h, but not useful in #if.
12475 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12476 define them any more.
12477 (VAL_MAX): New macro.
12478 (VALMASK): Use it.
12479 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12480 BITS_PER_EMACS_INT, in #if.
12481 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12482 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12483 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12484 * s/ms-w32.h (DATA_START):
12485 Move here from removed file m/intel386.h.
12486 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12487 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12488
12489 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12490
12491 Assume C89 or later.
12492 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12493 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12494 (xrealloc):
12495 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12496 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12497 * textprop.c, tparam.c (NULL): Remove.
12498 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12499 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12500 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12501 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12502 * xterm.c (input_signal_count): Assume volatile works.
12503
12504 2012-05-21 Ken Brown <kbrown@cornell.edu>
12505
12506 * xgselect.c (xg_select): Fix first argument in call to 'select'
12507 (bug#11508).
12508
12509 2012-05-20 Ken Brown <kbrown@cornell.edu>
12510
12511 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12512 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12513
12514 2012-05-19 Ken Brown <kbrown@cornell.edu>
12515
12516 * xfns.c (x_in_use): Remove `static' qualifier.
12517 * xterm.h (x_in_use): Declare.
12518 * xgselect.c: Include xterm.h.
12519 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12520 and `display_arg' (bug#9754).
12521
12522 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12523
12524 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12525
12526 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12527 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12528
12529 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12530
12531 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12532
12533 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12534 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12535
12536 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12537 reference to image_cache->refcount.
12538 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12539
12540 2012-05-17 Juri Linkov <juri@jurta.org>
12541
12542 * search.c (Fword_search_regexp, Fword_search_backward)
12543 (Fword_search_forward, Fword_search_backward_lax)
12544 (Fword_search_forward_lax): Move functions to isearch.el
12545 (bug#10145, bug#11381).
12546
12547 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12548
12549 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12550
12551 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12552
12553 * lread.c (init_obarray): Declare Qt and Qnil as special.
12554
12555 2012-05-14 Glenn Morris <rgm@gnu.org>
12556
12557 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12558 Put "libexec" before "bin", for the sake of init_callproc_1.
12559
12560 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12561
12562 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12563
12564 * unexaix.c: Port to more-recent AIX compilers.
12565 (report_error, report_error_1, make_hdr, copy_sym)
12566 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12567 Make arguments const char *, not char *, to avoid violations of C
12568 standard and to fix some AIX warnings reported by Gilles Pion.
12569
12570 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12571
12572 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12573 already have overlays loaded.
12574 (handle_single_display_spec): Before returning without displaying
12575 fringe bitmap, synchronize the bidi iterator with the main display
12576 iterator, by calling iterate_out_of_display_property.
12577 (iterate_out_of_display_property): Detect buffer iteration by
12578 testing that it->string is a Lisp string.
12579 (get_next_display_element): When the current object is exhausted,
12580 and there's something on it->stack, call set_iterator_to_next to
12581 proceed with what's on the stack, instead of returning zero.
12582 (set_iterator_to_next): If called at the end of a Lisp string,
12583 proceed to consider_string_end without incrementing string
12584 position. Don't increment display vector index past the end of
12585 the display vector. (Bug#11417)
12586 (pos_visible_p): Don't report a position visible when move_it_to
12587 stopped at the last line of window, which happens to be scanned
12588 backwards by the bidi iteration. (Bug#11464)
12589
12590 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12591
12592 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12593 and right-margin display specs even if the spec is invalid or we
12594 are on a TTY, and thus unable to display on the fringes.
12595 That's because the text with the property will not be displayed anyway,
12596 so we need to signal to the caller that this is a "replacing"
12597 display spec. This fixes display when the spec is invalid or we
12598 are on a TTY.
12599
12600 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12601
12602 * unexaix.c (make_hdr): Fix typo in prototype.
12603 This bug broke the build on AIX. Problem reported by Gilles Pion.
12604
12605 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12606
12607 * keyboard.c (kbd_buffer_get_event): Read special events also in
12608 batch mode. (Bug#11415)
12609
12610 2012-05-12 Glenn Morris <rgm@gnu.org>
12611
12612 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12613
12614 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12615
12616 * lisp.mk (lisp): Add newcomment.elc.
12617
12618 2012-05-12 Glenn Morris <rgm@gnu.org>
12619
12620 * Makefile.in (MKDIR_P): New, set by configure.
12621 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12622
12623 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12624
12625 Remove unused function hourglass_started.
12626 * dispextern.h (hourglass_started):
12627 * w32fns.c (hourglass_started):
12628 * xdisp.c (hourglass_started): Remove.
12629
12630 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12631
12632 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12633 Update dependencies.
12634
12635 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12636
12637 * xgselect.c (xg_select): Put maxfds+1 into a var.
12638 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12639
12640 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12641
12642 2012-05-10 Dave Abrahams <dave@boostpro.com>
12643
12644 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12645 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12646
12647 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12648
12649 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12650 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12651 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12652 Initialize xd_registered_buses.
12653
12654 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12655
12656 Untag more efficiently if USE_LSB_TAG.
12657 This is based on a proposal by YAMAMOTO Mitsuharu in
12658 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12659 For an admittedly artificial (nth 8000 longlist) benchmark on
12660 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12661 Emacs's overall text size by 1%.
12662 * lisp.h (XUNTAG): New macro.
12663 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12664 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12665 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12666 * eval.c (Fautoload):
12667 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12668 * frame.h (XFRAME): Use XUNTAG.
12669
12670 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12671 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12672 Remove unportable assumptions about print widths of types like
12673 dbus_uint32_t.
12674 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12675 intptr_t when converting between pointer and integer, to avoid GCC
12676 warnings about wrong width.
12677
12678 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12679
12680 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12681 stack for each reader_thread, instead of defaulting to 8MB
12682 determined by the linker. This avoids failures in creating
12683 subprocesses on Windows 7, see the discussion in this thread:
12684 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12685
12686 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12687
12688 Fix up display of the *Minibuf-0* buffer in the mini window.
12689 * keyboard.c (read_char): Don't clear the echo area if there's no
12690 message to clear.
12691 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12692 contents of *Minibuf-0*) if there's no message displayed in its stead.
12693
12694 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12695
12696 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12697 batch mode.
12698
12699 2012-05-06 Chong Yidong <cyd@gnu.org>
12700
12701 * lisp.mk (lisp): Update.
12702
12703 2012-05-05 Jim Meyering <meyering@redhat.com>
12704
12705 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12706
12707 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12708
12709 * data.c (PUT_ERROR): New macro.
12710 (syms_of_data): Use it. Add new error type `user-error'.
12711 * undo.c (user_error): New function.
12712 (Fprimitive_undo): Use it.
12713 * print.c (print_error_message): Adjust print style for `user-error'.
12714 * keyboard.c (user_error): New function.
12715 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12716
12717 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12718
12719 Do not limit current-time-string to years 1000..9999.
12720 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12721 (Fcurrent_time_string): Support any year that is supported by the
12722 underlying localtime representation. Don't use asctime, as it
12723 has undefined behavior for years outside the range -999..9999.
12724
12725 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12726
12727 Fix race conditions involving setenv, gmtime, localtime, asctime.
12728 Without this fix, interrupts could mess up code that uses these
12729 nonreentrant functions, since setting TZ invalidates existing
12730 tm_zone or tzname values, and since most of these functions return
12731 pointers to static storage.
12732 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12733 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12734 Grow the critical sections to include not just invoking
12735 localtime/gmtime, but also accessing these functions' results
12736 including their tm_zone values if any, and any related TZ setting.
12737 (format_time_string): Last arg is now struct tm *, not struct tm **,
12738 so that the struct tm is saved in the critical section.
12739 All callers changed. Simplify allocation of initial buffer, partly
12740 motivated by the fact that memory allocation needs to be outside
12741 the critical section.
12742
12743 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12744
12745 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12746 with RESET_INTERVAL.
12747
12748 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12749 Remove duplicated buffer name initialization.
12750
12751 2012-05-02 Jim Meyering <jim@meyering.net>
12752
12753 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12754
12755 * xfns.c (x_window): Use xstrdup (Bug#11375).
12756
12757 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12758
12759 * xdisp.c (pos_visible_p): If already at a newline from the
12760 display string before the 'while' loop, don't walk back the glyphs
12761 from it3.glyph_row. Solves assertion violation when the display
12762 string begins with a newline (egg.el). (Bug#11367)
12763
12764 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12765
12766 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12767 Move to simple.el.
12768
12769 2012-05-01 Glenn Morris <rgm@gnu.org>
12770
12771 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12772 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12773 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12774 All were removed before 23.1.
12775
12776 * dispnew.c: Remove HAVE_LIBNCURSES test;
12777 it is always true on relevant platforms.
12778
12779 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12780 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12781
12782 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12783
12784 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12785
12786 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12787 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12788 Remove.
12789
12790 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12791
12792 Do not avoid creating empty evaporating overlays (Bug#9642).
12793 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12794 That is, do not delete an evaporating overlay if it becomes
12795 empty after its bounds are adjusted to fit within its buffer.
12796 This fix caused other problems, and I'm reverting it until we get
12797 to the bottom of them.
12798
12799 2012-04-27 Chong Yidong <cyd@gnu.org>
12800
12801 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12802
12803 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12804
12805 * xdisp.c (pos_visible_p): If the window start position is beyond
12806 ZV, start the display from buffer beginning. Prevents assertion
12807 violation in init_iterator when the minibuffer window is scrolled
12808 via the scroll bar.
12809
12810 * window.c (window_scroll_pixel_based): Likewise.
12811
12812 2012-04-27 Chong Yidong <cyd@gnu.org>
12813
12814 * keymap.c (where_is_internal): Doc fix (Bug#10872).

12843
12844 * keyboard.c (read_char): Don't wipe echo area for select window
12845 events: These might get delayed via `mouse-autoselect-window'

12861 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12862 if it becomes empty after its bounds are adjusted to fit within
12863 its buffer. Without this fix, in a nonempty buffer (let ((o
12864 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12865 yields an empty overlay that has the evaporate property, which is
12866 not supposed to happen.

13028 Don't consider the header-line row as "partially visible", even if
13029 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

13201 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13202
13203 * xdisp.c (set_cursor_from_row): If the display string appears in
13204 the buffer at position that is closer to point than the position
13205 after the display string, display the cursor on the first glyph of
13206 the display string. Fixes cursor display when a 'display' text
13207 property immediately follows invisible text. (Bug#11094)
13208
13209 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13210
13211 composite.c: use 'double' consistently
13212 * composite.c (get_composition_id): Use 'double' consistently
13213 instead of converting 'float' to 'double' and vice versa; this is
13214 easier to understand and avoids a GCC warning.
13215
13216 2012-04-09 Glenn Morris <rgm@gnu.org>
13217
13218 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13219 preparation for dumping it with emacs. (Bug#4789)
13220 (leimdir): New variable.
13221 ($(leimdir)/leim-list.el): New rule.
13222 (emacs$(EXEEXT)): Depend on leim-list.el.

13237
13238 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13239
13240 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13241 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13242 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13243 objects, as mark_maybe_pointer will catch them otherwise.
13244 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13245 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
13246
13247 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13248
13249 Fix typo that broke non-Windows builds.
13250 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
13251

13261 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13262 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13263 [!WINDOWSNT]: New macros.
13264 (init_libxml2_functions, libxml2_loaded_p): New functions.
13265 (parse_region): Call fn_xmlCheckVersion instead of using the macro

13268 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13269 linked in).

13271 Call init_libxml2_functions before calling libxml2 functions.
13272 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13273
13274 * emacs.c: Don't include libxml/parser.h.
13275 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13276 xmlCleanupParser directly.
13277
13278 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13279
13280 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13281
13282 * indent.c (Fvertical_motion): If there is a display string at
13283 point, use it.vpos to compute how many lines to backtrack after
13284 move_it_to point. (Bug#11133)
13285
13286 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13287
13288 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13289 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13290 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13291 macros related to unification of CJK characters. For the details,
13292 see the discussion following the message here:
13293 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13294
13295 2012-04-04 Chong Yidong <cyd@gnu.org>

13298
13299 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13300
13301 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13302 instead of alloca. (Bug#11138)
13303
13304 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13305
13306 * w32menu.c (is_simple_dialog): Properly check lisp types.

13308
13309 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13310
13311 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13312 position we get to after a call to move_it_to fails the
13313 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13314 only if we wind up in a string from display property. (Bug#11063)
13315
13316 * window.c (Fdelete_other_windows_internal): Invalidate the row
13317 and column information about mouse highlight, so that redisplay
13318 restores it after reallocating the glyph matrices. (Bug#7464)
13319
13320 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13321 string comes from a `display' text property, use the buffer
13322 position of that property as if we actually saw that position in
13323 the row's glyphs.
13324 (move_it_by_lines): Remove the assertion that
13325 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13326 violated when there's a before-string at the beginning of a line.
13327 (Bug#11063)
13328
13329 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13330
13331 * xdisp.c (append_space_for_newline): If the default face was
13332 remapped, use the remapped face for the appended newline.
13333 (extend_face_to_end_of_line): Use the remapped default face for
13334 extending the face to the end of the line.
13335 (display_line): Call extend_face_to_end_of_line when the default
13336 face was remapped. (Bug#11068)
13337
13338 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13339
13340 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

13345
13346 2012-03-27 Glenn Morris <rgm@gnu.org>
13347
13348 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13349 Doc fixes.
13350
13351 2012-03-26 Kenichi Handa <handa@m17n.org>
13352
13353 * dispextern.h (struct glyph): Fix previous change. Change the
13354 bit length of glyphless.ch to 25 (Bug#11082).
13355
13356 2012-03-26 Chong Yidong <cyd@gnu.org>
13357
13358 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13359 (command_loop_1): Use it; inhibit selection update for
13360 handle-select-window too (Bug#8996).
13361
13362 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13363
13364 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13365
13366 2012-03-25 Kenichi Handa <handa@m17n.org>
13367
13368 * dispextern.h (struct glyph): Change the bit length of
13369 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13370
13371 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13372
13373 * s/ms-w32.h (tzname): Include time.h before redirecting to
13374 _tzname. Fixes the MSVC build. (Bug#9960)

13383
13384 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13385
13386 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13387 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13388 when fetching a multibyte character consumes more bytes than
13389 CHAR_BYTES returns, due to unification of CJK characters in
13390 string_char. (Bug#11073)
13391
13392 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13393
13394 * process.c (wait_reading_process_output): Handle pty disconnect
13395 by refraining from sending oneself a SIGCHLD (bug#10933).
13396
13397 2012-03-22 Chong Yidong <cyd@gnu.org>
13398
13399 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13400
13401 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13402 Mark string as coming from a prefix property.
13403 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13404 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13405
13406 2012-03-21 Chong Yidong <cyd@gnu.org>
13407
13408 * xfaces.c (Vface_remapping_alist): Doc fix.
13409
13410 2012-03-20 Eli Zaretskii <eliz@gnu.org>

13414 Doc fixes.
13415
13416 2012-03-20 Chong Yidong <cyd@gnu.org>
13417
13418 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13419 to reflect default non-nil value of redisplay-dont-pause.
13420
13421 2012-03-19 Kenichi Handa <handa@m17n.org>
13422
13423 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13424 it fit in a valid range (Bug#11003).
13425
13426 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13427
13428 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13429 that is not from display property, accept the row as a "cursor
13430 row" if one of the string's character has a non-nil `cursor'
13431 property. Fixes cursor positioning when there are newlines in
13432 overlay strings, e.g. in icomplete.el. (Bug#11035)
13433
13434 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13435
13436 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13437
13438 2012-03-12 Chong Yidong <cyd@gnu.org>
13439
13440 * eval.c (inhibit_lisp_code): Rename from
13441 inhibit_window_configuration_change_hook; move from window.c.
13442
13443 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13444 * window.c (run_window_configuration_change_hook)
13445 (syms_of_window): Callers changed.
13446
13447 2012-03-11 Chong Yidong <cyd@gnu.org>
13448
13449 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13450
13451 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13452
13453 2012-03-10 Chong Yidong <cyd@gnu.org>
13454
13455 * frame.c (other_visible_frames): Don't assume the selected frame
13456 is visible (Bug#10955).
13457
13458 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13459
13460 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13461
13462 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13463
13464 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13465 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13466 zero (Bug#10954).
13467
13468 2012-03-03 Glenn Morris <rgm@gnu.org>
13469

13475 position past the first glyph_row that ends at ZV. (Bug#10902)
13476 (redisplay_window, next_element_from_string): Fix typos in
13477 comments.
13478 (redisplay_window): Pass to move_it_vertically the margin in
13479 pixels, not in screen lines.
13480
13481 2012-03-02 Glenn Morris <rgm@gnu.org>
13482
13483 * buffer.c (buffer-list-update-hook): Doc fix.
13484
13485 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13486
13487 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13488 push_it before setting up the iterator for the first overlay
13489 string, even if we have an empty string loaded.
13490 (next_overlay_string): If there's an empty string on the iterator
13491 stack, pop the stack. (Bug#10903)
13492
13493 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13494
13495 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13496 Suggested by Stefan Monnier in
13497 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13498 * alloc.c (widen_to_Lisp_Object): New static function.
13499 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13500 and widening them to Lisp_Objects. This would work even if
13501 USE_LSB_TAG is defined and wide integers are used, which might
13502 happen in a future version of Emacs.
13503
13504 2012-02-25 Chong Yidong <cyd@gnu.org>
13505
13506 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13507 Doc fix.
13508
13509 * xselect.c (Fx_selection_exists_p): Doc fix.
13510 (x_clipboard_manager_save_all): Print an informative message
13511 before saving to clipboard manager.
13512
13513 2012-02-24 Chong Yidong <cyd@gnu.org>
13514
13515 * keyboard.c (process_special_events): Handle all X selection
13516 requests in kbd_buffer, not just the next one (Bug#8869).
13517
13518 2012-02-23 Chong Yidong <cyd@gnu.org>
13519
13520 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13521 call when setting menu-bar-lines and tool-bar-lines parameters.
13522 (unwind_create_frame_1): New helper function.
13523
13524 * window.c (inhibit_window_configuration_change_hook): New var.
13525 (run_window_configuration_change_hook): Obey it.
13526 (syms_of_window): Initialize it.
13527
13528 2012-02-22 Chong Yidong <cyd@gnu.org>
13529
13530 * xterm.c (x_draw_image_relief): Add missing type check for
13531 Vtool_bar_button_margin (Bug#10743).
13532
13533 2012-02-21 Chong Yidong <cyd@gnu.org>
13534
13535 * fileio.c (Vfile_name_handler_alist): Doc fix.
13536
13537 * buffer.c (Fget_file_buffer): Protect against invalid file
13538 handler return value.
13539
13540 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13541
13542 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13543 when computing $valmask.
13544
13545 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13546 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13547 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13548 It's useless in that case, and it can cause problems on hosts
13549 that allocate halves of EMACS_INT values separately.
13550 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13551 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13552 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13553 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13554 it avoids undefined behavior on hosts where shifting right by more
13555 than the word width has undefined behavior.
13556
13557 2012-02-19 Chong Yidong <cyd@gnu.org>
13558
13559 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

13563 return values (Bug#10845).
13564
13565 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13566
13567 * .gdbinit (pitx): Fix incorrect references to fields of the

13573
13574 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13575
13576 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13577 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.

13579 2012-02-15 Chong Yidong <cyd@gnu.org>
13580
13581 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13582 marked as special. Also, starting docstrings with * is obsolete.

13596
13597 2012-02-12 Chong Yidong <cyd@gnu.org>
13598
13599 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13600 as that creates a dangerous corner case.
13601
13602 * window.c (Fdelete_window_internal): Invalidate the mouse

14192 (get_current_wm_state): Set net_wm_state_hidden_seen to 1 if
14193 _NET_WM_STATE_HIDDEN is in NET_WM_STATE.
14194
14195 2011-11-28 Paul Eggert <eggert@cs.ucla.edu>

14225 _MSC_VER.

14334 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14335 Otherwise, valgrind does not work on some platforms.
14336 Problem reported by Andreas Schwab in
14337 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14338 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14339 is set, removing the need for VIRT_ADDRESS_VARIES.
14340 (PURE_P): Use a more-efficient implementation that needs just one
14341 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14342 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14343 to 4 (xorl, subq, cmpq, setbe).
14344 * alloc.c (pure): Always extern now, since that's the
14345 VIRT_ADDR_VARIES behavior.
14346 (PURE_POINTER_P): Use a single comparison, not two, for
14347 consistency with the new puresize.h.
14348 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14349 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
14350 Remove VIRT_ADDR_VARIES no longer needed.

14353
14354 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
14355 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14356 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14357 behave as if the cursor position were at the window margin.
14358
14359 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14360 and the cursor position is out of bounds, behave as if the cursor
14361 position were at the window margin. (Bug#10075)
14362
14363 2011-11-18 Chong Yidong <cyd@gnu.org>
14364
14365 * window.c (Fwindow_combination_limit): Make first argument

14367 selected window.
14368
14369 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>

14381 hash values of the two rows.
14382 (copy_row_except_pointers): Preserve the used[] arrays and the
14383 hash values of the two rows. (Bug#10035)
14384 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14385
14386 * xdisp.c (row_hash): New function, body extracted from
14387 compute_line_metrics.
14388 (compute_line_metrics): Call row_hash, instead of computing the
14389 hash code inline.
14390
14391 * dispnew.c (verify_row_hash): Call row_hash for computing the
14392 hash code of a row, instead of duplicating code from xdisp.c.

14410 of Vwindow_splits.
14411
14412 2011-11-16 Juanma Barranquero <lekktu@gmail.com>

14434 * xdisp.c (display_line): Move the call to
14435 highlight_trailing_whitespace before the call to

14446
14447 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14448 with user-defined heap size. Bump the default size of the temacs

14501 Avoid some portability problems by eschewing 'extern inline' functions.
14502 The trivial performance wins aren't worth the portability hassles; see
14503 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>

14533
14534 * w32.c (check_windows_init_file): Don't look for term/w32-win.el

14552
14553 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).

14581 Otherwise, these inline functions do not conform to C99 and
14582 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14583 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14584 * intervals.c (adjust_intervals_for_insertion)

14587 (static_offset_intervals): Remove.
14588 (offset_intervals): Rewrite using the old contents of
14589 static_offset_intervals. The old version didn't conform to C99
14590 because an extern inline function contained a reference to an
14591 identifier with static linkage.

14613 (Fwindow_vscroll): Doc fix.
14614 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14615 argument, since it makes no sense to pass a live window and for
14616 consistency with window-child.

14815 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14816 <oslsachem@gmail.com> for helping to debug this.
14817
14818 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14819 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14820 (g_b_init_get_glyph_outline_w): New static variables.
14821 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14822 (GetGlyphOutlineW_Proc): New typedefs.
14823 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14824 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14825 New functions.
14826 (w32font_open_internal, compute_metrics):
14827 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14828 instead of calling the "wide" APIs directly.
14829
14830 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14831
14832 * w32.h (syms_of_w32font): Add prototype.
14833
14834 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14835

14837 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14838 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14839 (Fmove_to_window_line): Doc fix.
14840
14841 2011-10-27 Chong Yidong <cyd@gnu.org>
14842
14843 * process.c (make_process): Set gnutls_state to NULL.
14844
14845 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14846 non-NULL, regardless of GNUTLS_INITSTAGE.
14847 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14848 an error. Set process slots as soon as we allocate them.
14849
14850 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14851
14852 2011-10-27 Chong Yidong <cyd@gnu.org>
14853
14854 * gnutls.c (emacs_gnutls_deinit): New function.
14855 Deallocate credentials structures as well as calling gnutls_deinit.
14856 (Fgnutls_deinit, Fgnutls_boot): Use it.
14857
14858 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14859 (deactivate_process): Call emacs_gnutls_deinit.
14860
14861 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14862
14863 * image.c (x_create_x_image_and_pixmap):
14864 * w32.c (sys_rename, w32_delayed_load):
14865 * w32font.c (fill_in_logfont):
14866 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14867
14868 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14869
14870 * w32fns.c (w32_default_color_map): New function,
14871 extracted from Fw32_default_color_map.
14872 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14873
14874 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14875
14876 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14877
14878 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14879
14880 * keyboard.c (test_undefined): New function (bug#9751).
14881 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14882
14883 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14884
14885 * sysdep.c (init_sys_modes): Fix the check for the controlling
14886 terminal (Bug#6649).
14887
14888 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14889
14890 * dispextern.h (struct bidi_it): New member next_en_type.
14891
14892 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14893 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14894 current character, check also for next_en_type being WEAK_EN.
14895 (bidi_resolve_weak): Don't enter the expensive loop if the current
14896 position is before next_en_pos. Record the bidi type of the first
14897 non-ET, non-BN character we find, in addition to its position.
14898 (bidi_level_of_next_char): Invalidate next_en_type when
14899 next_en_pos is over-stepped.
14900
14901 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14902
14903 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14904 * editfns.c: Rewrite current-time-zone so that it invokes
14905 the equivalent of (format-time-string "%Z") to get the time zone name.
14906 This fixes a bug when the time zone name contains characters that
14907 need converting from the system time locale to Emacs internal format.
14908 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14909 that patch fixed format-time-string to do the conversion, but
14910 I forgot to fix current-time-zone.
14911 (format_time_string): New function, containing most of
14912 what Fformat_time_string used to contain.
14913 (Fformat_time_string): Rewrite in terms of format_time_string.
14914 This doesn't change this function's behavior.
14915 (current-time-zone): Rewrite to use format_time_string.
14916 This fixes the bug reported by Michael Schierl in
14917 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14918 Jason Rumney's 2007-06-07 change worked around this bug, but
14919 didn't fix it.
14920 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14921
14922 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14923
14924 * xdisp.c (start_display): If the character at POS is displayed
14925 via a display vector, reset IT->current.dpvec_index to zero.
14926 (try_window_reusing_current_matrix): If a line ends in a display
14927 vector or the next line starts in a display vector, continue
14928 redrawing the window even though the character position of
14929 start_row was reached.
14930 (Bug#9771, part 2)
14931
14932 2011-10-18 Chong Yidong <cyd@gnu.org>
14933
14934 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14935 with nobreak-char-display too.
14936
14937 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14938
14939 Fix part 3 of bug#9771.
14940 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14941 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14942 non-neutral characters if the current character is a paragraph
14943 separator (a.k.a. Newline). This avoids running the same
14944 expensive loop twice, once when we consume the preceding newline
14945 and the other time when the line actually needs to be displayed.
14946 Avoid the loop when we see neutrals on the base embedding level
14947 following a character whose directionality is the same as the
14948 paragraph's. This avoids running the expensive loop when a line
14949 ends in a long sequence of neutrals, like control characters.
14950 Add assertion against STRONG_AL type. Slightly rearrange code
14951 that determines the type of a neutral given the first non-neutral
14952 that follows it.
14953 (bidi_level_of_next_char): Set next_en_pos to zero when
14954 invalidating its info.
14955
14956 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14957
14958 * xdisp.c (push_display_prop): Determine whether to record string
14959 or buffer position by IT->string, not by IT->method. Allow
14960 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14961 (move_it_vertically_backward): Don't look for character position
14962 immediately after the newline when in a continuation line.
14963 (Bug#9771, part 1)
14964
14965 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14966
14967 * window.c (coordinates_in_window): Rewrite and delabelize
14968 vertical border check. (Bug#5357) (Bug#9618)
14969
14970 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14971
14972 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14973 errors in XSetWindowBorder (bug#9310).
14974
14975 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14976
14977 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14978 avoid crash when xmalloc overrun checking is enabled.
14979
14980 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14981
14982 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14983 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14984 cursor motion with <left> and <right> arrow keys.
14985
14986 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14987 some callers set that themselves.
14988
14989 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14990
14991 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14992 display string and the previous row comes from the same string and
14993 is empty. (Bug#9739) (Bug#9738)
14994
14995 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14996
14997 * doc.c (get_doc_string): Encode file name (bug#9735).
14998
14999 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15000
15001 * bidi.c (bidi_level_of_next_char):
15002 * xdisp.c (get_visually_first_element): Remove old incorrect
15003 comments regarding the Unicode Line Separator character.
15004
15005 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15006
15007 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15008
15009 * alloc.c (Fgc_status): Do not access beyond zombies array
15010 boundary if nzombies > MAX_ZOMBIES.
15011 * alloc.c (dump_zombies): Add missing format specifier.
15012
15013 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15014
15015 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15016 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15017
15018 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15019 Some packages use them to denote characters with modifiers.
15020
15021 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15022
15023 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15024 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15025 matching a pp-number. Rename parameter var to var1.
15026
15027 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15028
15029 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15030
15031 2011-10-08 Glenn Morris <rgm@gnu.org>
15032
15033 * callint.c (Fcall_interactively): Give a more explicit error for the
15034 'c' case with a non-character input. (Bug#8479)
15035
15036 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15037
15038 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15039 lines.
15040 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15041 lines that are hscrolled on the left.
15042
15043 * dispnew.c (buffer_posn_from_coords): Account for a possible
15044 presence of header-line. (Bug#4426)
15045
15046 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15047
15048 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15049 Don't advertise functionality which we discourage or doesn't work.
15050
15051 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15052
15053 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15054 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15055 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15056 this makes Emacs dump core during garbage collection on rare
15057 occasions. sizeof is obviously inferior to offsetof here, so
15058 stick with offsetof.
15059 (GC_POINTER_ALIGNMENT): New macro.
15060 (mark_memory): Omit 3rd (offset) arg; caller changed.
15061 Don't assume EMACS_INT alignment is the same as pointer alignment.
15062
15063 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15064
15065 * keyboard.c (read_key_sequence_remapped): New var.
15066 (read_key_sequence): Compute remapping in the right buffer.
15067 (command_loop_1): Use read_key_sequence's remapping directly.
15068
15069 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15070
15071 * dired.c (file_name_completion): Don't expand file name.
15072 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15073 before checking file name handler.
15074
15075 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15076 they've been requested explicitly (bug#9591).
15077
15078 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15079
15080 * keymap.c (Fsingle_key_description): Use make_specified_string
15081 instead of build_string to build string from push_key_description.
15082 (Bug#5193)
15083
15084 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15085
15086 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15087 This fixes a Y2038 bug on 64-bit hosts.
15088 * buffer.c (reset_buffer):
15089 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15090 (Fclear_buffer_auto_save_failure):
15091 Use 0, not -1, to represent an unset failure time, since time_t
15092 might not be signed.
15093
15094 Remove dependency on glibc malloc internals.
15095 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15096 Move back here from lisp.h, but with their new implementations.
15097 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15098 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15099 * charset.c (charset_table_init): New static var.
15100 (syms_of_charset): Use it instead of xmalloc. This removes a
15101 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15102 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15103 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15104 Move back to alloc.c.
15105 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15106 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15107
15108 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15109
15110 * nsterm.m (windowDidResize): Call x_set_window_size only when
15111 ns_in_resize is true. Otherwise set pixelwidth/height and
15112 call change_frame_size (Bug#9628).
15113
15114 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15115
15116 Port --enable-checking=all to Fedora 14 x86-64.
15117 * charset.c (syms_of_charset): Also account for glibc malloc's
15118 internal overhead when calculating the initial malloc maximum.
15119
15120 Port --enable-checking=all to Fedora 14 x86.
15121 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15122 Move to lisp.h.
15123 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15124 (overrun_check_realloc, overrun_check_free):
15125 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15126 That way, xmalloc returns a properly-aligned pointer even if
15127 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15128 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15129 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15130 into account when calculating the initial malloc maximum.
15131 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15132 Move here from alloc.c, so that charset.c can use it too.
15133 Properly align; the old code wasn't right for common 32-bit hosts
15134 when configured with --enable-checking=all.
15135 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15136 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15137
15138 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15139
15140 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15141 use EDOM.
15142
15143 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15144
15145 * xdisp.c (compute_display_string_end): If there's no display
15146 string at CHARPOS, return -1.
15147
15148 * bidi.c (bidi_fetch_char): When compute_display_string_end
15149 returns a negative value, treat the character as a normal
15150 character not covered by a display string. (Bug#9624)
15151
15152 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15153
15154 * lread.c (Fread_from_string): Fix typo in docstring.
15155
15156 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15157
15158 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15159 newline, reseat the iterator instead of bidi-iterating there one
15160 character at a time. (Bug#9610)
15161 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15162 TO_CHARPOS if the bidi iterator is at base embedding level.
15163
15164 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15165
15166 * lread.c (readevalloop): Use correct code for NBSP.
15167 (read1): Likewise. (Bug#9608)
15168
15169 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15170
15171 * dbusbind.c (Fdbus_register_signal): When service is not
15172 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15173
15174 2011-09-25 Glenn Morris <rgm@gnu.org>
15175
15176 * buffer.c (truncate-lines): Doc fix.
15177
15178 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15179
15180 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15181 (Fset_window_next_buffers): Doc fix.
15182
15183 2011-09-24 Glenn Morris <rgm@gnu.org>
15184
15185 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15186
15187 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15188
15189 Fix minor problems found by static checking.
15190 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15191 * indent.c (Fvertical_motion): Fix == vs = typo.
15192

15195 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15196 Default value is now t. Doc fix.
15197
15198 * indent.c (Fvertical_motion): Compute and apply the overshoot
15199 logic when moving up, not only when moving down. Fix the
15200 confusing name and values of the it_overshoot_expected variable;
15201 logic changes accordingly. (Bug#9254) (Bug#9549)
15202
15203 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15204 CHARPOS is covered by a display string which includes newlines.
15205 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15206 is covered by a display string with embedded newlines.

15216
15217 do not ignore write error for any output size
15218 The previous change was incomplete.
15219 While it makes emacs --batch detect the vast majority of stdout
15220 write failures, errors were still ignored whenever the output size is
15221 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15222 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15223 && echo FAIL: ignored write error
15224 FAIL: ignored write error
15225 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15226 && echo FAIL: ignored write error
15227 FAIL: ignored write error
15228 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15229
15230 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15231
15232 * emacs.c (Fkill_emacs): In noninteractive mode exit
15233 non-successfully if a write error occurred on stdout. (Bug#9574)
15234
15235 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15236
15237 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15238 the xassert test.
15239
15240 * dispextern.h (struct it): Update the comment documenting what
15241 can it->OBJECT be.
15242
15243 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15244
15245 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15246 a display string, extend search for cursor position to end of row.
15247 (find_row_edges): If the row ends in a newline from a display
15248 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15249 Handle the case of a display string with multiple newlines.
15250 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15251 non-empty line. Fixes confusing cursor motion with arrow keys at
15252 the beginning of a line that starts with whitespace.
15253
15254 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>

15263
15264 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15265
15266 * xdisp.c (display_line): Record maximum and minimum buffer
15267 positions even if no glyphs were produced (e.g., by a zero-width
15268 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15269 buffer positions that will be removed from the glyph row because
15270 they don't fit.
15271 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15272 column is beyond frame width: don't subtract 1 "pixel" when
15273 computing width of the stretch.
15274 (reseat_at_next_visible_line_start): Undo the change made on
15275 2011-09-17 that saved paragraph information and restored it after
15276 the call to `reseat'. (Bug#9545)
15277

15283 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15284

15289
15290 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15291
15292 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15293
15294 Fix minor problem found by static checking.
15295 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15296 initialized, to pacify gcc -Wuninitialized.
15297
15298 * fileio.c: Report proper errno when syscall falls.
15299 (Finsert_file_contents): Save and restore errno,
15300 so that report_file_error outputs the correct diagnostic.
15301 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15302
15303 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15304
15305 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15306
15307 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15308
15309 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

15311
15312 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15313
15314 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15315 about the current paragraph and restore it after the call to reseat.
15316
15317 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15318 (bidi_find_paragraph_start): Search back for paragraph beginning
15319 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15320 (bidi_move_to_visually_next): Only trigger paragraph-related
15321 computations when the last character is a newline or at EOB, not
15322 just any NEUTRAL_B. (Bug#9470)
15323
15324 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15325 truncated lines if point is covered by a display string. (Bug#9524)

15328
15329 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15330 (cons_to_x_long): New function.
15331 (lisp_data_to_selection_data): Use it. Correct the test for
15332 short-versus-long data; it was negated. Break out of vector
15333 loop, for efficiency, when a long datum is discovered.
15334
15335 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15336
15337 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15338
15339 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15340
15341 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15342 GCC PR/17406) by declaring this function with external scope.
15343
15344 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15345
15346 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15347 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15348
15349 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15350

15361 of TAB characters in a composition.
15362
15363 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15364
15365 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15366 This occurs when processing a multibyte format.
15367 Problem reported by Wolfgang Jenker.
15368
15369 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15370

15383
15384 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15385
15386 * xselect.c: Use signed conversions more consistently (Bug#9498).
15387 (selection_data_to_lisp_data): Assume incoming selection data are
15388 signed integers, not unsigned. This is to be consistent with
15389 outgoing selection data, which was modified to use signed integers
15390 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15391 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15392 expects long, not unsigned long.

15394 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15395

15405
15406 * indent.c (compute_motion): Process display vector front to back

15421
15422 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15423

15425 value for non-existent files.
15426
15427 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15428
15429 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15430 set its "size" to -1. This will set the modtime_size field of
15431 the corresponding buffer to -1, which is what
15432 verify-visited-file-modtime expects for files that do not exist.

15434
15435 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15436
15437 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15438 here ...
15439 * lisp.h: ... from here. push_key_description is no longer
15440 defined in keyboard.c, so its declaration should not be in
15441 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15442 logically belongs with push_key_description.
15443
15444 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15445
15446 * buffer.h: Include <sys/types.h> instead of <time.h>.
15447 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15448 Problem reported by Herbert J. Skuhra.

15465 2011-09-09 Eli Zaretskii <eliz@gnu.org>

15469 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15470
15471 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):

15474 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

15488
15489 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15490 Without this fix, the command to link temacs failed due to an
15491 undefined symbol __builtin_isnan. This is because
15492 /usr/include/iso/math_c99.h #defines isnan(x) to
15493 __builtin_isnan(x), but the bundled gcc, which identifies itself
15494 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15495 a __builtin_isnan.
15496 * floatfns.c (isnan): #undef, and then #define to a clone of
15497 what's in data.c.
15498 (Fisnan): Always define, since it's always available now.
15499 (syms_of_floatfns): Always define isnan at the Lisp level.
15500
15501 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15502
15503 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15504
15505 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15506
15507 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15508 The previous code assumed that file offsets (off_t values) fit in
15509 EMACS_INT variables, which is not true on typical 32-bit hosts.
15510 The code messed up by falsely reporting buffer overflow in cases
15511 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15512 when "big" contains more than 2**29 bytes, even though this
15513 inserts just one byte and does not overflow the buffer.
15514 (Finsert_file_contents): Store file offsets as off_t
15515 values, not as EMACS_INT values. Check for overflow when
15516 converting between EMACS_INT and off_t. When checking for
15517 buffer overflow or for overlap, take the offsets into account.
15518 Don't use EMACS_INT for small values where int suffices.
15519 When checking for overlap, fix a typo: ZV was used where
15520 ZV_BYTE was intended.
15521 (Fwrite_region): Don't assume off_t fits into 'long'.
15522 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15523
15524 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15525
15526 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15527
15528 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15529
15530 sprintf-related integer and memory overflow issues (Bug#9412).
15531
15532 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15533 (esprintf, exprintf, evxprintf): New functions.
15534 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15535 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15536 (modify_event_symbol): Do not assume that the length of
15537 name_alist_or_stem is safe to alloca and fits in int.
15538 (Fexecute_extended_command): Likewise for function name and binding.
15539 (Frecursion_depth): Wrap around reliably on integer overflow.
15540 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15541 since some callers pass EMACS_INT values.
15542 (Fsingle_key_description): Don't crash if symbol name contains more
15543 than MAX_ALLOCA bytes.
15544 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15545 (get_minibuffer): Arg is now EMACS_INT, not int.
15546 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15547 (esprintf, exprintf, evxprintf): New decls.
15548 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15549
15550 * dbusbind.c (signature_cat): New function.
15551 (xd_signature, Fdbus_register_signal):
15552 Do not overrun buffer; instead, report string overflow.
15553
15554 * dispnew.c (add_window_display_history): Don't overrun buffer.
15555 Truncate instead; this is OK since it's just a log.
15556
15557 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15558 even if the time zone offset is outlandishly large.
15559 Don't mishandle offset == INT_MIN.
15560
15561 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15562 when creating daemon; the previous buffer-overflow check was incorrect.
15563
15564 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15565 which has the guts of the old verror function.
15566
15567 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15568 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15569
15570 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15571 (font_unparse_xlfd): Don't blindly alloca long strings.
15572 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15573 fits in int, when using sprintf. Use single snprintf to count
15574 length of string rather than counting it via multiple sprintfs;
15575 that's simpler and more reliable.
15576 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15577 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15578 sprintf, in case result does not fit in int.
15579
15580 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15581 (fontset_from_font): Print it.
15582
15583 * frame.c (tty_frame_count): Now printmax_t, not int.
15584 (make_terminal_frame, set_term_frame_name): Print it.
15585 (x_report_frame_params): In X, window IDs are unsigned long,
15586 not signed long, so print them as unsigned.
15587 (validate_x_resource_name): Check for implausibly long names,
15588 and don't assume name length fits in 'int'.
15589 (x_get_resource_string): Don't blindly alloca invocation name;
15590 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15591 not fit in int.
15592
15593 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15594 (xg_check_special_colors, xg_set_geometry):
15595 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15596
15597 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15598 Use esprintf, not sprintf, in case result does not fit in int.
15599
15600 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15601 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15602 it as a large positive number.
15603 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15604 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15605
15606 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15607 in case result does not fit in int.
15608
15609 * print.c (float_to_string): Detect width overflow more reliably.
15610 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15611 buffer overrun. Don't assume list length fits in 'int'. Treat
15612 print length of 0 as 0, not as infinity; to be consistent with other
15613 uses of print length in this function. Don't overflow print length
15614 index. Don't assume hash table size fits in 'long', or that
15615 vectorlike size fits in 'unsigned long'.
15616
15617 * process.c (make_process): Use printmax_t, not int, to format
15618 process-name gensyms.
15619
15620 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15621
15622 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15623 to avoid potential buffer overrun.
15624
15625 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15626 if X resource line is longer than 512 bytes.
15627
15628 * xfns.c (x_window): Make sprintf buffer a bit bigger
15629 to avoid potential buffer overrun.
15630
15631 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15632
15633 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15634
15635 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15636
15637 Integer overflow fixes for scrolling, etc.
15638 Without these, Emacs silently mishandles large integers sometimes.
15639 For example, "C-u 4294967297 M-x recenter" was treated as if
15640 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15641
15642 * xdisp.c (try_window_id): Check Emacs fixnum range before
15643 converting to 'int'.
15644
15645 * window.c (window_scroll_line_based, Frecenter):
15646 Check that an Emacs fixnum is in range before assigning it to 'int'.
15647 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15648 values converted from Emacs fixnums.
15649 (Frecenter): Don't wrap around a line count if it is out of 'int'
15650 range; instead, treat it as an extreme value.
15651 (Fset_window_configuration, compare_window_configurations):
15652 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15653
15654 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15655 that can exceed INT_MAX. Check that EMACS_INT value is in range
15656 before assigning it to the (possibly-narrower) index.
15657 (match_limit): Don't assume that a fixnum can fit in 'int'.
15658
15659 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15660 exceed INT_MAX.
15661
15662 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15663 (Fvertical_motion): Don't wrap around LINES values that don't fit
15664 in 'int'. Instead, treat them as extreme values. This is good
15665 enough for windows, which can't have more than INT_MAX lines anyway.
15666
15667 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15668
15669 * Require libxml/parser.h to avoid compilation warning.
15670
15671 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15672
15673 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15674 since this reportedly can destroy thread storage.
15675
15676 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15677
15678 * syntax.c (find_defun_start): Update all cache variables if
15679 exiting early (Bug#9401).
15680
15681 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15682
15683 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15684
15685 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15686 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15687 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15688
15689 * term.c (tty_append_glyph): New function.
15690 (produce_stretch_glyph): Static function and its prototype deleted.
15691
15692 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15693 Add prototypes.
15694
15695 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15696
15697 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15698 when checking :margin (Bug#9390).
15699 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15700 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15701 so that the name doesn't mislead. All uses changed.
15702
15703 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15704
15705 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15706 set_tty_hooks.
15707
15708 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15709
15710 * xdisp.c (move_it_to): Don't bail out early when reaching
15711 position beyond to_charpos, if we are scanning backwards.
15712 (move_it_vertically_backward): When DY == 0, make sure we get to
15713 the first character in the line after the newline.
15714
15715 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15716
15717 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15718 (ccl_driver): Do not generate an out-of-range pointer.
15719 (Fccl_execute_on_string): Remove unnecessary check for
15720 integer overflow, noted by Stefan Monnier in
15721 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15722 Remove a FIXME that didn't need fixing.
15723 Simplify the newly-introduced buffer reallocation code.
15724
15725 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15726
15727 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15728
15729 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15730
15731 Integer and memory overflow issues (Bug#9196).
15732
15733 * doc.c (get_doc_string): Rework so that
15734 get_doc_string_buffer_size is the actual buffer size, rather than
15735 being 1 less than the actual buffer size; this makes xpalloc more
15736 convenient.
15737
15738 * image.c (x_allocate_bitmap_record, cache_image):
15739 * xselect.c (Fx_register_dnd_atom):
15740 Simplify previous changes by using xpalloc.
15741
15742 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15743 since either will do and ptrdiff_t is convenient with xpalloc.
15744
15745 * charset.c (charset_table_size)
15746 (struct charset_sort_data.priority): Now ptrdiff_t.
15747 (charset_compare): Don't overflow if priorities differ greatly.
15748 (Fsort_charsets): Don't assume list length fits in int.
15749 Check for size-calculation overflow when allocating sort data.
15750 (syms_of_charset): Allocate an initial charset table that is
15751 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15752
15753 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15754
15755 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15756 The actual value is always <= INT_MAX, and leaving it unsigned made
15757 overflow checking harder.
15758
15759 * dispextern.h (struct glyph_matrix.rows_allocated)
15760 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15761 with xpalloc. The values are still always <= INT_MAX.
15762
15763 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15764
15765 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15766 (SAFE_NALLOCA): New macro.
15767
15768 * region-cache.c (struct boundary.pos, find_cache_boundary)
15769 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15770 (set_cache_region, invalidate_region_cache)
15771 (revalidate_region_cache, know_region_cache, region_cache_forward)
15772 (region_cache_backward, pp_cache):
15773 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15774 so that ptrdiff_t * can be passed to xpalloc.
15775 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15776 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15777 (pp_cache): Don't assume cache_len fits in int.
15778 * region-cache.h: Adjust extern decls to match.
15779
15780 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15781 EMACS_INT, since either will do, for xpalloc.
15782
15783 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15784 (xnmalloc, xnrealloc, xpalloc): New functions.
15785
15786 * bidi.c (bidi_shelve_header_size): New constant.
15787 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15788 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15789
15790 * bidi.c (bidi_cache_shrink):
15791 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15792 (overlay_strings):
15793 Don't update size of array until after memory allocation succeeds,
15794 because xmalloc/xrealloc may not return.
15795 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15796 now that we have proper integer overflow checking.
15797 (record_overlay_string, overlay_strings): Catch overflows when
15798 calculating size of overlay_str_buf.
15799
15800 * callproc.c (Fcall_process): Check for size overflow when
15801 calculating size of args2.
15802 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15803 Normally we prefer signed values, but sticking with ptrdiff_t would
15804 require adding more-complicated checks.
15805
15806 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15807 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15808 Redo buffer-overflow calculations to avoid integer overflow.
15809 Add a FIXME comment where memory seems to be over-allocated.
15810
15811 * character.c (Fstring): Check for size-calculation overflow.
15812
15813 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15814 unnecessary integer overflow. Check for size overflow.
15815 (encode_coding_object): Don't update size until xmalloc succeeds.
15816
15817 * composite.c (get_composition_id): Check for overflow in glyph
15818 length calculations.
15819
15820 Integer and memory overflow fixes for display code.
15821 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15822 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15823 (scrolling_window): Check for overflow in size calculations.
15824 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15825 Don't assume glyph table len fits in int.
15826 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
15827 (row_table_size): Now ptrdiff_t, not int.
15828 (scrolling_window): Avoid overflow in size calculations.
15829 Don't update size until allocation succeeds.
15830 * fns.c (concat): Check for overflow in size calculations.
15831 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15832 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15833 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15834
15835 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15836 (get_doc_string): Check for size calculation overflow.
15837 Don't update size until allocation succeeds.
15838 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15839 EMACS_INT, where ptrdiff_t will do.
15840 (Fsubstitute_command_keys): Check for string overflow.
15841
15842 * editfns.c (set_time_zone_rule): Don't assume environment length
15843 fits in int.
15844 (message_length): Now ptrdiff_t, not int.
15845 (Fmessage_box): Don't update size until allocation succeeds.
15846 Don't assume message length fits in int.
15847 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15848
15849 * emacs.c (main): Do not reallocate argv, since there is a null at
15850 the end that can be overwritten, and this way there's no need to
15851 worry about size-calculation overflow.
15852 (sort_args): Check for size-calculation overflow.
15853
15854 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15855 alloc succeeds.
15856 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15857
15858 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15859 (x_set_scroll_bar_width, x_figure_window_size):
15860 Check for integer overflow.
15861 (x_set_alpha): Do not assume XINT fits in int.
15862
15863 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15864 This is for the members text_lines, text_cols, total_lines, total_cols,
15865 where the system imposes an 'int' limit.
15866
15867 * fringe.c (Fdefine_fringe_bitmap):
15868 Don't update size until alloc works.
15869
15870 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15871 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15872
15873 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15874 Check for size-calculation overflow.
15875 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15876 do, as we prefer signed integers.
15877 (id_to_widget.max_size, id_to_widget.used)
15878 (xg_store_widget_in_map, xg_remove_widget_from_map)
15879 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15880 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15881 Use and return ptrdiff_t, not int.
15882 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15883 * gtkutil.h: Change prototypes to match the above.
15884
15885 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15886 are duplicate now that they've been promoted to lisp.h.
15887 (x_allocate_bitmap_record, x_alloc_image_color)
15888 (make_image_cache, cache_image, xpm_load):
15889 Don't update size until alloc is done.
15890 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15891 (x_detect_edges):
15892 Check for size calculation overflow.
15893 (ct_colors_allocated_max): New constant.
15894 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15895 overflow.
15896
15897 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15898 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15899 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15900 Use ptrdiff_t, not int, to count maps.
15901 (read_char_minibuf_menu_prompt): Check for overflow in size
15902 calculations. Don't update size until allocation succeeds.
15903 Redo calculations to avoid overflow.

15925
15926 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15927 overflow. Don't bother calling xmalloc when xrealloc will do.
15928
15929 * search.c (Freplace_match): Check for size calculation overflow.
15930 (Fset_match_data): Don't assume list lengths fit in 'int'.
15931
15932 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15933 for command line length. Do not attempt to address one before the
15934 beginning of an array, as that's not portable.
15935
15936 * term.c (max_frame_lines): Remove; unused.
15937 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15938 not int.
15939 (encode_terminal_code, calculate_costs): Check for size
15940 calculation overflow.
15941 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
15942 table lengths and related sizes. Don't update size until alloc
15943 done. Redo calculations to avoid overflow.
15944 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15945
15946 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15947 subtracting pointers.
15948 (gobble_line): Check for overflow more carefully. Don't update size
15949 until alloc done.
15950
15951 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15952 Don't update size until alloc done.
15953 Redo size calculations to avoid overflow.
15954 Check for size calculation overflow.

15962 Use ptrdiff_t, not int, for sizes.
15963 (Finternal_make_lisp_face, cache_face):
15964 Check for size calculation overflow.
15965 (cache_face): Treat size calculation overflows as if they were
15966 memory exhaustion (the usual treatment), rather than aborting.
15967
15968 * xfns.c (x_encode_text, x_set_name_internal)
15969 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15970 sizes, since they can exceed INT_MAX in size. Check for size
15971 calculation overflow.
15972
15973 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15974 (xg_select): Check for size calculation overflow.
15975 Don't update size until alloc done.
15976
15977 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15978 as sprintf is limited to int lengths.
15979
15980 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15981 (X_LONG_MIN): New macros.
15982 Use them to make the following changes clearer.
15983 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15984 This change doesn't affect the value now, but it may help remind
15985 future maintainers not to raise the value too much later.
15986 (SELECTION_QUANTUM): Remove, replacing with ...
15987 (selection_quantum): ... new function, which avoids overflow.
15988 All uses changed.
15989 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15990 assumption that selection length fits in 'int'.

15995 Use ptrdiff_t, not int, to record length of selection.
15996 (x_reply_selection_request, x_get_window_property)
15997 (receive_incremental_selection, x_property_data_to_lisp):
15998 Redo calculations to avoid overflow.
15999 (x_reply_selection_request): When sending hint, ceiling it at
16000 X_LONG_MAX rather than relying on wraparound overflow to send
16001 something.
16002 (x_get_window_property, receive_incremental_selection)
16003 (lisp_data_to_selection_data, x_property_data_to_lisp):
16004 Check for size-calculation overflow.
16005 (x_get_window_property, receive_incremental_selection)
16006 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16007 Don't store size until memory allocation succeeds.
16008 (x_get_window_property): Plug memory leak on memory exhaustion.
16009 Don't double-block input; malloc is safe here. Don't assume 2**34
16010 - 4 fits in unsigned long. Add an xassert to check
16011 XGetWindowProperty overflow. Be more careful about overflow
16012 calculations, and distinguish size from memory overflow better.
16013 (receive_incremental_selection): When tracing, don't assume
16014 unsigned int is less than INT_MAX.
16015 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16016 harmful) conversions of unsigned short to int.
16017 (lisp_data_to_selection_data): Don't assume that integers
16018 in the range -65535 through -1 fit in an X unsigned short.
16019 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16020 result parameters unless successful. Rely on cons_to_unsigned
16021 to report problems with elements; the old code wasn't right anyway.
16022 (x_check_property_data): Check for int overflow; we cannot use
16023 a wider type due to X limits.
16024 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16025
16026 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

16032 Don't assume alloca size is less than MAX_ALLOCA.
16033 (x_term_init): Don't assume length fits in int (sprintf is limited
16034 to int size).
16035
16036 Use ptrdiff_t for composition IDs.
16037 * character.c (lisp_string_width):

16056 * lisp.h (hash_lookup, hash_put):
16057 * minibuf.c (Ftest_completion):
16058 Use ptrdiff_t for hash table indexes, not int (which is too
16059 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16060 32-bit --with-wide-int hosts).
16061
16062 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16063 Add a FIXME comment about memory leaks.
16064 (syms_of_charset): Don't assume xmalloc returns.
16065
16066 Don't assume that stated character widths fit in int.

16068 * character.h (CHAR_WIDTH):
16069 * indent.c (MULTIBYTE_BYTES_WIDTH):
16070 Use sanitize_char_width to avoid undefined and/or bad behavior
16071 with outlandish widths.
16072 * character.h (sanitize_tab_width): Rename from sanitize_width,
16073 now that we have two such functions. All uses changed.
16074 (sanitize_char_width): New inline function.
16075
16076 Don't assume that tab-width fits in int.
16077 * character.h (sanitize_width): New inline function.
16078 (SANE_TAB_WIDTH): New macro.
16079 (ASCII_CHAR_WIDTH): Use it.
16080 * indent.c (sane_tab_width): Remove. All uses replaced by

16086
16087 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16088 Remove unreachable code.
16089 (read_hex, load_charset_map_from_file): Check for integer overflow.
16090
16091 * xterm.c: Don't go over XClientMessageEvent limit.
16092 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16093 (x_send_scroll_bar_event): Likewise. Check that the size does not
16094 exceed limits imposed by XClientMessageEvent, as well as the usual
16095 ptrdiff_t and size_t limits.
16096
16097 * keyboard.c: Overflow, signedness and related fixes.
16098 (make_lispy_movement): Use same integer type in forward decl
16099 that is used in the definition.
16100 (read_key_sequence, keyremap_step):
16101 Change bufsize argument back to int, undoing my 2011-03-30 change.
16102 We prefer signed types, and int is wide enough here.
16103 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16104 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16105 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16106 length, not size_t. Use ptrdiff_t for index, not int.
16107 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16108 possibility of integer overflow.
16109
16110 Overflow, signedness and related fixes for images.

16120 * xdisp.c (calc_pixel_width_or_height):
16121 * xfns.c (image_cache_refcount):
16122 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16123 on typical 64-bit hosts.
16124
16125 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16126 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
16127 Omit unnecessary casts to int.
16128 (parse_image_spec): Check that integers fall into 'int' range
16129 when the callers expect that.
16130 (image_ascent): Redo ascent calculation to avoid int overflow.
16131 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16132 (lookup_image): Remove unnecessary tests.
16133 (xbm_image_p): Locals are now of int, not EMACS_INT,
16134 since parse_image_check makes sure they fit into int.
16135 (png_load, gif_load, svg_load_image):
16136 Prefer int to unsigned where either will do.
16137 (tiff_handler): New function, combining the cores of the
16138 old tiff_error_handler and tiff_warning_handler.
16139 This function is rewritten to use vsnprintf and thereby avoid
16140 stack buffer overflows. It uses only the features of vsnprintf
16141 that are common to both POSIX and native Microsoft.
16142 (tiff_error_handler, tiff_warning_handler): Use it.
16143 (tiff_load, gif_load, imagemagick_load_image):
16144 Don't assume :index value fits in 'int'.
16145 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16146 (imagemagick_load_image): Check that crop parameters fit into
16147 the integer types that MagickCropImage accepts. Don't assume
16148 Vimagemagick_render_type has a nonnegative value. Don't assume
16149 size_t fits in 'long'.
16150 (gs_load): Use printmax_t to print the widest integers possible.
16151 Check for integer overflow when computing image height and width.

16154
16155 * xdisp.c (redisplay_window): Don't force window start if point
16156 will be invisible in the resulting window. (Bug#9324)

16159
16160 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16161 the display spec is of the form `(space ...)'.
16162 (handle_display_spec): Return the value returned by
16163 handle_single_display_spec, not just 1 or zero.
16164 (handle_single_display_spec): If the display spec is of the form
16165 `(space ...)', and specifies display in the text area, return 2
16166 rather than 1.
16167 (try_cursor_movement): Check for the need to scroll more
16168 accurately, and prefer exact match for point under bidi.
16169 Don't advance `row' beyond the last row of the window.
16170
16171 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16172 into disp_prop; all users changed.
16173
16174 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16175 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16176 for the text covered by the display property.

16187 buffers, return left-to-right.
16188 (set_cursor_from_row): Consider candidate row a win if its glyph
16189 represents a newline and point is on that newline. Fixes cursor
16190 positioning on the newline at EOL of R2L text within L2R
16191 paragraph, and vice versa.
16192 (try_cursor_movement): Check continued rows, in addition to
16193 continuation rows. Fixes unwarranted scroll when point enters a
16194 continued line of R2L text within an L2R paragraph, or vice versa.
16195 (cursor_row_p): Consider the case of point being equal to
16196 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16197 from the end of a short line to the beginning of a continued line
16198 of R2L text within L2R paragraph.
16199 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16200 composed characters.
16201
16202 * bidi.c (bidi_check_type): Use xassert.
16203 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
16204 members.

16221
16222 * xdisp.c (redisplay_window): When computing centering_position,
16223 account for the height of the header line. (Bug#8874)
16224
16225 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16226 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16227 candidate is selected by the mouse, and that candidate has a
16228 composed character under the mouse.
16229
16230 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16231 coordinates reported by pos-visible-in-window-p for a composed
16232 character in column zero.

16240 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16241 consider it a hit if to_charpos is anywhere in the range of the
16242 composed buffer positions.
16243
16244 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16245
16246 * image.c (gif_load): Don't assume that each subimage has the same
16247 dimensions as the base image. Handle disposal method that is
16248 "undefined" by the gif spec (Bug#9335).
16249

16259 from an Org mode buffer to a Speedbar frame.
16260
16261 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16262 a composition, take its buffer position from IT->cmp_it.charpos.
16263 Fixes cursor positioning at the beginning of a line that begins
16264 with a composed character.
16265
16266 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16267
16268 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16269 character bidirectional type, use STRONG_L instead. Fixes crashes
16270 in a buffer produced by `describe-categories'.
16271
16272 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16273 members before the level stack, so they would be saved and
16274 restored when copying iterator state. Fixes incorrect reordering
16275 around TABs covered by display properties.
16276

16392 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16393 (Fnetwork_interface_list): Allocate in increments of bytes instead
16394 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16395 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16396 sockaddr.
16397 (struct ifflag_def): notrailers is smart on OSX.
16398 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16399 Get hardware address with getifaddrs if available.
16400
16401 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16402
16403 * xdisp.c (iterate_out_of_display_property): xassert that
16404 IT->position is set to within IT->object's boundaries. Break from
16405 the loop as soon as EOB is reached; avoids infloops in redisplay
16406 when IT->position is set up wrongly due to some bug.
16407 Set IT->current to match the bidi iterator unconditionally.
16408 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16409 entry. Force push_it to save on the stack the current
16410 buffer/string position, to be restored by pop_it. Fix flags in
16411 the iterator structure wrt the object coming from a display
16412 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16413 properties. (Bug#9284)
16414
16415 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16416
16417 * fontset.c (fontset_get_font_group): Add proper type checks.
16418 (Bug#9172)
16419
16420 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16421
16422 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16423 and LC_VERSION_MIN_MACOSX.
16424 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16425 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16426
16427 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16428
16429 * xdisp.c (forward_to_next_line_start): Allow to use the
16430 no-display-properties-and-no-overlays under bidi display.
16431 Set disp_pos in the bidi iterator to avoid searches for display
16432 properties and overlays.
16433
16434 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16435
16436 * editfns.c (Fset_time_zone_rule): Document relationship with the
16437 setenv function.
16438
16439 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16440 the font entity extracted from the cache (Bug#8109).
16441
16442 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16443
16444 * composite.c (autocmp_chars): Don't reset point. That is done by
16445 restore_point_unwind (Bug#5984).
16446
16447 2011-08-07 Juri Linkov <juri@jurta.org>
16448
16449 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16450 to show the arg `TIME' instead of `TIMEVAL'.
16451
16452 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16453
16454 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16455 display property strides EOL and includes a newline, as in
16456 longlines-mode. (Bug#9254)
16457 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16458 word-wrap under bidirectional display. (Bug#9224)
16459
16460 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16461 is non-zero, even if the data buffer is NULL. Fixes a crash in
16462 vertical-motion with longlines-mode. (Bug#9254)
16463
16464 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16465
16466 * bidi.c <bidi_cache_total_alloc>: Now static.
16467 (bidi_initialize): Initialize bidi_cache_total_alloc.
16468
16469 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16470 cache. (Bug#9221)
16471
16472 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16473 amount allocated this far in `bidi_cache_total_alloc'.
16474 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16475 non-zero, only free the data buffer without restoring the cache
16476 contents. All callers changed.
16477
16478 * dispextern.h (bidi_unshelve_cache): Update prototype.
16479
16480 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16481 (move_it_in_display_line, move_it_to)
16482 (move_it_vertically_backward, move_it_by_lines): Replace the call
16483 to xfree to an equivalent call to bidi_unshelve_cache.
16484 (move_it_in_display_line_to): Fix logic of returning
16485 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16486
16487 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16488
16489 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16490 came from a string character with a `cursor' property. (Bug#9229)
16491
16492 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16493
16494 * Makefile.in (LIB_PTHREAD): New variable.
16495 (LIBES): Add LIB_PTHREAD (Bug#9216).
16496
16497 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16498 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16499
16500 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16501
16502 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16503
16504 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16505
16506 * xterm.c (x_find_topmost_parent): New function.
16507 (x_set_frame_alpha): Find topmost parent window with
16508 x_find_topmost_parent and set the property there also (bug#9181).
16509 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16510
16511 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16512
16513 * callproc.c (Fcall_process): Avoid vfork clobbering
16514 the local vars buffer, coding_systems, current_dir.
16515
16516 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16517
16518 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16519
16520 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16521
16522 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16523 so that it is not optimized away.
16524
16525 * xdisp.c (compute_display_string_pos): Remove unused local.
16526
16527 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16528
16529 Fix slow cursor motion and scrolling in large buffers with
16530 selective display, like Org Mode buffers. (Bug#9218)
16531
16532 * dispextern.h (struct bidi_it): New member disp_prop_p.
16533
16534 * xdisp.c: Remove one-slot cache of display string positions.
16535 (compute_display_string_pos): Accept an additional argument
16536 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16537 for a display string or property. If found, set DISP_PROP_P
16538 non-zero.
16539
16540 * bidi.c (bidi_fetch_char): Accept an additional argument
16541 DISP_PROP_P, and pass it to compute_display_string_pos.
16542 Only handle text covered by a display string if DISP_PROP_P is returned
16543 non-zero. All callers of bidi_fetch_char changed.
16544
16545 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16546
16547 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16548
16549 2010-12-03 Don March <don@ohspite.net>
16550
16551 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16552 last character M-[char] is translated to ESC [char] (bug#7541).
16553
16554 2011-08-02 Kenichi Handa <handa@m17n.org>
16555
16556 * lisp.h (uniprop_table): Extern it.
16557
16558 * chartab.c (uniprop_table): Make it non-static.
16559
16560 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16561
16562 * xdisp.c (forward_to_next_line_start): Accept additional argument
16563 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16564 on the newline.
16565 (reseat_at_next_visible_line_start): Use the bidi iterator state
16566 returned by forward_to_next_line_start to restore the state of
16567 it->bidi_it after backing up to previous newline. (Bug#9212)
16568
16569 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16570
16571 * regex.c (re_comp): Protoize.
16572 (re_exec): Fix return type.
16573 (regexec): Fix type of `ret'. (Bug#9203)
16574
16575 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16576
16577 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16578 This is needed if max-image-size is a floating-point number.
16579
16580 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16581
16582 * print.c (print_object): Print empty symbol as ##.
16583
16584 * lread.c (read1): Read ## as empty symbol.
16585
16586 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16587
16588 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16589 setting frame foreground color (Bug#9175).
16590 (x_set_background_color): Likewise.
16591
16592 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16593 contents (Bug#9176).
16594 (EmacsTooltip -init): Remove bezels and add shadows to
16595 tooltip windows.
16596
16597 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16598 or scroll bar (Bug#8470).
16599
16600 * nsfont.m (nsfont_open): Remove assignment to voffset and
16601 unnecessary vars hshink, expand, hd, full_height, min_height.
16602 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16603
16604 * nsterm.h (nsfont_info): Remove voffset field.
16605
16606 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16607
16608 Implement strike-through and overline on NextStep (Bug#8863).
16609
16610 * nsfont.m (nsfont_open): Use underline position provided by font,
16611 instead of hard-coded value of 2.
16612 (nsfont_draw): Call ns_draw_text_decoration instead.
16613
16614 * nsterm.h: Add declaration for ns_draw_text_decoration.
16615
16616 * nsterm.m (ns_draw_text_decoration): New function for drawing
16617 underline, overline, and strike-through.
16618 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16619 ns_draw_text_decoration. Change treatment of cursor drawing to
16620 accommodate underlining, etc.
16621
16622 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16623
16624 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16625 default.
16626
16627 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16628
16629 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16630 Without this fix, if a signal arrives just after memory fills up,
16631 'malloc' might be invoked reentrantly.
16632
16633 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16634 In other words, assume that every image size is allowed, on non-X
16635 hosts. This assumption is probably wrong, but it lets Emacs compile.
16636
16637 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16638
16639 * regex.c (re_iswctype): Convert return values to boolean.
16640
16641 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16642
16643 * xdisp.c (compute_display_string_pos): Don't use cached display
16644 string position if the buffer had its restriction changed.
16645 (Bug#9184)
16646
16647 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16648
16649 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16650
16651 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16652
16653 Integer signedness and overflow and related fixes. (Bug#9079)
16654
16655 * bidi.c: Integer size and overflow fixes.
16656 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16657 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16658 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16659 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16660 (bidi_find_other_level_edge):
16661 Use ptrdiff_t instead of EMACS_INT where either will do.
16662 This works better on 32-bit hosts configured --with-wide-int.
16663 (bidi_cache_ensure_space): Check for size-calculation overflow.
16664 Use % rather than repeated addition, for better worst-case speed.
16665 Don't set bidi_cache_size until after xrealloc returns, because it
16666 might not return.
16667 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16668 (bidi_cache_ensure_space): Also check that the bidi cache size
16669 does not exceed that of the largest Lisp string or buffer. See Eli
16670 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16671
16672 * alloc.c (__malloc_size_t): Remove.
16673 All uses replaced by size_t. See Andreas Schwab's note
16674 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16675
16676 * image.c: Improve checking for integer overflow.
16677 (check_image_size): Assume that f is nonnull, since
16678 it is always nonnull in practice. This is one less thing to
16679 worry about when checking for integer overflow later.
16680 (x_check_image_size): New function, which checks for integer
16681 overflow issues inside X.
16682 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16683 This removes the need for a memory_full check.
16684 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16685 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16686 (xbm_read_bitmap_data): Change locals back to 'int', since
16687 their values must fit in 'int'.
16688 (xpm_load_image, png_load, tiff_load):
16689 Invoke x_create_x_image_and_pixmap earlier,
16690 to avoid much needless work if the image is too large.
16691 (tiff_load): Treat overly large images as if
16692 x_create_x_image_and_pixmap failed, not as malloc failures.
16693 (gs_load): Use x_check_image_size.
16694
16695 * gtkutil.c: Omit integer casts.
16696 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16697 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16698
16699 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16700
16701 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16702 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16703 would wrongly return t on a 64-bit host.
16704
16705 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16706 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16707 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16708 and therefore cause GCC to emit a bogus diagnostic in some cases.
16709
16710 * image.c: Integer signedness and overflow and related fixes.
16711 This is not an exhaustive set of fixes, but it's time to
16712 record what I've got.
16713 (lookup_pixel_color, check_image_size): Remove redundant decls.
16714 (check_image_size): Don't assume that arbitrary EMACS_INT values
16715 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16716 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16717 (tiff_load, imagemagick_load_image):
16718 Check for overflow in size calculations.
16719 (x_create_x_image_and_pixmap): Remove unnecessary test for
16720 xmalloc returning NULL; that can't happen.
16721 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16722 (xpm_color_bucket): Use better integer hashing function.
16723 (xpm_cache_color): Don't possibly over-allocate memory.
16724 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16725 (gif_memory_source):
16726 Use ptrdiff_t, not int or size_t, to record sizes.
16727 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16728 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16729 either works, as we prefer signed integers.
16730 (tiff_read_from_memory, tiff_write_from_memory):
16731 Return tsize_t, not size_t, since that's what the TIFF API wants.
16732 (tiff_read_from_memory): Don't fail simply because the read would
16733 go past EOF; instead, return a short read.
16734 (tiff_load): Omit no-longer-needed casts.
16735 (Fimagemagick_types): Don't assume size fits into 'int'.
16736
16737 Improve hashing quality when configured --with-wide-int.
16738 * fns.c (hash_string): New function, taken from sxhash_string.
16739 Do not discard information about ASCII character case; this
16740 discarding is no longer needed.
16741 (sxhash-string): Use it. Change sig to match it. Caller changed.
16742 * lisp.h: Declare it.
16743 * lread.c (hash_string): Remove, since we now use fns.c's version.
16744 The fns.c version returns a wider integer if --with-wide-int is
16745 specified, so this should help the quality of the hashing a bit.
16746
16747 * emacs.c: Integer overflow minor fix.
16748 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16749 Define only if GNU_LINUX.
16750 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16751
16752 * dispnew.c: Integer signedness and overflow fixes.
16753 Remove unnecessary forward decls, that were a maintenance hassle.
16754 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16755 All uses changed.
16756 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16757 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16758 (prepare_desired_row, line_draw_cost):
16759 Use int, not unsigned, where either works.
16760 (save_current_matrix, restore_current_matrix):
16761 Use ptrdiff_t, not size_t, where either works.
16762 (init_display): Check for overflow more accurately, and without
16763 relying on undefined behavior.
16764
16765 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16766 Remove, replacing with the new symbols in lisp.h. All uses changed.
16767 * fileio.c (make_temp_name):
16768 * filelock.c (lock_file_1, lock_file):
16769 * xdisp.c (message_dolog):
16770 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16771 Use pMd etc. instead.
16772 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16773 replacing the pWIDE etc. symbols removed from editfns.c.
16774
16775 * keyboard.h (num_input_events): Now uintmax_t.
16776 This is (very slightly) less likely to mess up due to wraparound.
16777 All uses changed.
16778
16779 * buffer.c: Integer signedness fixes.
16780 (alloc_buffer_text, enlarge_buffer_text):
16781 Use ptrdiff_t rather than size_t when either will do, as we prefer
16782 signed integers.
16783
16784 * alloc.c: Integer signedness and overflow fixes.
16785 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16786 (__malloc_size_t): Default to size_t, not to int.
16787 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16788 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16789 Prefer ptrdiff_t to size_t when either would do, as we prefer
16790 signed integers.
16791 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16792 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16793 Now const. Initialize with values that are in range even if char
16794 is signed.
16795 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16796 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16797 These functions do the right thing with sizes > 2**32.
16798 (check_depth): Now ptrdiff_t, not int.
16799 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16800 Adjust to new way of storing sizes. Check for size overflow bugs
16801 in rest of code.
16802 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16803 slightly wrong anyway, as it missed one instance of
16804 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16805 (refill_memory_reserve): Omit needless cast to size_t.
16806 (mark_object_loop_halt): Mark as externally visible.
16807
16808 * xselect.c: Integer signedness and overflow fixes.
16809 (Fx_register_dnd_atom, x_handle_dnd_message):
16810 Use ptrdiff_t, not size_t, since we prefer signed.
16811 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16812 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16813 x_dnd_atoms_size and x_dnd_atoms_length.
16814
16815 * doprnt.c: Prefer signed to unsigned when either works.
16816 * eval.c (verror):
16817 * doprnt.c (doprnt):
16818 * lisp.h (doprnt):
16819 * xdisp.c (vmessage):
16820 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16821 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16822 prefer signed arithmetic to avoid comparison confusion.
16823 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16824 but is a bit tricky.
16825
16826 Assume freestanding C89 headers, string.h, stdlib.h.
16827 * data.c, doprnt.c, floatfns.c, print.c:
16828 Include float.h unconditionally.
16829 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16830 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16831 * regex.c: Likewise for stddef.h, string.h.
16832 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16833 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16834 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16835 (STDC_HEADERS): Remove obsolete defines.
16836 * sysdep.c: Include limits.h unconditionally.
16837
16838 Assume support for memcmp, memcpy, memmove, memset.
16839 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16840 * regex.c (memcmp, memcpy):
16841 Remove; we assume C89 now.
16842
16843 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16844 (__malloc_safe_bcopy): Remove; no longer needed.
16845
16846 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16847 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16848 well either way, and we prefer signed to unsigned.
16849
16850 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16851
16852 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16853 closes the connection while we're reading (bug#9182).
16854
16855 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16856
16857 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16858 are specified (Bug#9168).
16859
16860 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16861
16862 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16863 Found by GCC static checking and --with-wide-int on a 32-bit host.
16864
16865 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16866
16867 * xdisp.c (compute_display_string_pos): Fix logic of caching
16868 previous display string position. Initialize cached_prev_pos to
16869 -1. Fixes slow-down at the beginning of a buffer.
16870
16871 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16872
16873 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16874 for attrs[LFACE_FONTSET_INDEX].
16875
16876 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16877
16878 * xml.c (parse_region): Remove unused local
16879 that was recently introduced.
16880
16881 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16882
16883 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16884 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16885
16886 * xdisp.c (move_it_in_display_line_to): Record the best matching
16887 position for TO_CHARPOS while scanning the line, and restore it on
16888 exit if none of the characters scanned was an exact match.
16889 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16890 when exact match is impossible due to invisible text, and the
16891 lines are truncated.
16892
16893 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16894
16895 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16896 for OSX >= 10.7.
16897
16898 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16899
16900 Fix a significant slow-down of cursor motion with C-n, C-p,
16901 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16902 auto-repeat under bidi redisplay in fontified buffers.
16903 * xdisp.c (compute_stop_pos_backwards): New function.
16904 (next_element_from_buffer): Call compute_stop_pos_backwards to
16905 find a suitable prev_stop when we find ourselves before
16906 base_level_stop.
16907 (reseat): Don't look for prev_stop, as that could mean a very long
16908 run.
16909 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16910 <cached_disp_overlay_modiff>: Cache for last found display string
16911 position.
16912 (compute_display_string_pos): Return the cached position if asked
16913 about the same buffer in the same area of character positions, and
16914 the buffer wasn't changed since the time the display string
16915 position was cached.
16916
16917 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16918
16919 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16920 is an integer, which is important for empty lines. (Bug#9149)
16921
16922 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16923
16924 * frame.c (Fmodify_frame_parameters): In tty case, update the
16925 default face if necessary (Bug#4238).
16926
16927 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16928
16929 * editfns.c (Fstring_to_char): No need to explain what a character
16930 is in the docstring (Bug#6576).
16931
16932 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16933
16934 * xml.c (parse_region): Make sure we always return a tree.
16935
16936 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16937
16938 * xml.c (parse_region): If a document contains only comments,
16939 return that, too.
16940
16941 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16942
16943 * xml.c (make_dom): Return comments, too.
16944
16945 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16946
16947 Port to OpenBSD.
16948 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16949 and the surrounding thread.
16950 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16951 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16952 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16953 timer goes off.
16954 * s/openbsd.h (BROKEN_SIGIO): Define.
16955 * unexelf.c (unexec) [__OpenBSD__]:
16956 Don't update the .mdebug section of the Alpha COFF symbol table.
16957
16958 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16959
16960 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16961 (bug#8460).
16962
16963 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16964
16965 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16966 This fixes some race conditions on the permissions of any newly
16967 created file.
16968
16969 * alloc.c (valid_pointer_p): Use pipe, not open.
16970 This fixes some permissions issues when debugging.
16971
16972 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16973 If fchown fails to set both uid and gid, try to set just gid,
16974 as that is sometimes allowed. Adjust the file's mode to eliminate
16975 setuid or setgid bits that are inappropriate if fchown fails.
16976
16977 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16978
16979 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16980 to compare Lisp_Objects.
16981 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16982 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16983 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16984
16985 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16986
16987 * lread.c (read_integer): Unread even EOF character.
16988 (read1): Likewise. Properly record start position of symbol.
16989
16990 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16991 symbol character follows.
16992
16993 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16994
16995 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16996 This works around a problem with the previous change to Fcopy_file.
16997 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16998 and without this change, GCC might complain about discarding
16999 fchown's return value.
17000
17001 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17002
17003 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17004
17005 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17006
17007 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17008
17009 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17010
17011 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17012 it's used from the C level.
17013
17014 * process.c: Use the same condition for POLL_FOR_INPUT in both
17015 keyboard.c and process.c (bug#1858).
17016
17017 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17018
17019 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17020 (Fgnutls_boot): Use it.
17021
17022 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17023
17024 * doc.c (Fsubstitute_command_keys): Revert last change.
17025
17026 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17027
17028 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17029 quotes the next character, and doesn't affect other longer
17030 sequences (bug#8935).
17031
17032 * lread.c (syms_of_lread): Clarify that is isn't only
17033 `eval-buffer' and `eval-defun' that's affected by
17034 `lexical-binding' (bug#8460).
17035
17036 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17037
17038 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17039 bidi redisplay when a line includes both an image and is truncated.
17040
17041 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17042
17043 Fix minor problems found by static checking.
17044 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17045 (elsz): Now a signed constant, not a size_t var. We prefer signed
17046 types to unsigned, to avoid integer comparison confusion. Without
17047 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17048 "cannot optimize loop, the loop counter may overflow", a symptom
17049 of the confusion.
17050 * indent.c (Fvertical_motion): Mark locals as initialized.
17051 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17052
17053 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17054
17055 * search.c (Fre_search_backward): Mention `case-fold-search' in
17056 all the re_search_* functions (bug#8138).
17057
17058 * keyboard.c (Fopen_dribble_file): Document when the file is
17059 closed (bug#8056).
17060
17061 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17062
17063 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17064 bidi_cache_idx.
17065
17066 Support bidi reordering of display and overlay strings.
17067 * xdisp.c (compute_display_string_pos)
17068 (compute_display_string_end): Accept additional argument STRING.
17069 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17070 (reseat_to_string): Initialize bidi_it->string.s and
17071 bidi_it->string.schars.
17072 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17073 NULL (avoids a crash in bidi_paragraph_init).
17074 Initialize itb.string.lstring.
17075 (init_iterator): Call bidi_init_it only of a valid
17076 buffer position was specified. Initialize paragraph_embedding to
17077 L2R.
17078 (reseat_to_string): Initialize the bidi iterator.
17079 (display_string): If we need to ignore text properties of
17080 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17081 original value of -1 will not work with bidi.)
17082 (compute_display_string_pos): First arg is now struct
17083 `text_pos *'; all callers changed. Support display properties on
17084 Lisp strings.
17085 (compute_display_string_end): Support display properties on Lisp
17086 strings.
17087 (init_iterator, reseat_1, reseat_to_string): Initialize the
17088 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17089 when iterating on a string not from display properties).
17090 (compute_display_string_pos, compute_display_string_end):
17091 Fix calculation of the object to scan. Fixes an error when using
17092 arrow keys.
17093 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17094 base_level_stop; instead, set base_level_stop to BEGV.
17095 Fixes crashes in vertical-motion.
17096 (next_element_from_buffer): Improve commentary for when
17097 the iterator is before prev_stop.
17098 (init_iterator): Initialize bidi_p from the default value of
17099 bidi-display-reordering, not from buffer-local value. Use the
17100 buffer-local value only if initializing for buffer iteration.
17101 (handle_invisible_prop): Support invisible properties on strings
17102 that are being bidi-reordered.
17103 (set_iterator_to_next): Support bidi reordering of C strings and
17104 Lisp strings.
17105 (next_element_from_string): Support bidi reordering of Lisp
17106 strings.
17107 (handle_stop_backwards): Support Lisp strings as well.
17108 (display_string): Support display of R2L glyph rows.
17109 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17110 (init_iterator): Don't initialize it->bidi_p for strings
17111 here.
17112 (reseat_to_string): Initialize it->bidi_p for strings here.
17113 (next_element_from_string, next_element_from_c_string)
17114 (next_element_from_buffer): Add xassert's for correspondence
17115 between IT's object being iterated and it->bidi_it.string
17116 structure.
17117 (face_before_or_after_it_pos): Support bidi iteration.
17118 (next_element_from_c_string): Handle the case of the first string
17119 character that is not the first one in the visual order.
17120 (get_visually_first_element): New function, refactored from common
17121 parts of next_element_from_buffer, next_element_from_string, and
17122 next_element_from_c_string.
17123 (tool_bar_lines_needed, redisplay_tool_bar)
17124 (display_menu_bar): Force left-to-right direction. Add a FIXME
17125 comment for making that be controlled by a user option.
17126 (push_it, pop_it): Save and restore the state of the
17127 bidi iterator. Save and restore the bidi_p flag.
17128 (pop_it): Iterate out of display property for string iteration as
17129 well.
17130 (iterate_out_of_display_property): Support iteration over strings.
17131 (handle_single_display_spec): Set up it->bidi_it for iteration
17132 over a display string, and call bidi_init_it.
17133 (handle_single_display_spec, next_overlay_string)
17134 (get_overlay_strings_1, push_display_prop): Set up the bidi
17135 iterator for displaying display or overlay strings.
17136 (forward_to_next_line_start): Don't use the shortcut if
17137 bidi-iterating.
17138 (back_to_previous_visible_line_start): If handle_display_prop
17139 pushed the iterator stack, restore the internal state of the bidi
17140 iterator by calling bidi_pop_it same number of times.
17141 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17142 and we are bidi-iterating, don't decrement the iterator position;
17143 instead, set the first_elt flag in the bidi iterator, to produce
17144 the same effect.
17145 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17146 (push_display_prop): xassert that we are iterating a buffer.
17147 (push_it, pop_it): Save and restore paragraph_embedding member.
17148 (handle_single_display_spec, next_overlay_string)
17149 (get_overlay_strings_1, reseat_1, reseat_to_string)
17150 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17151 correctly. Don't assume unibyte strings are not bidi-reordered.
17152 (compute_display_string_pos)
17153 (compute_display_string_end): Fix handling the case of C string.
17154 (push_it, pop_it): Save and restore from_disp_prop_p.
17155 (handle_single_display_spec, push_display_prop): Set the
17156 from_disp_prop_p flag.
17157 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
17158 (pop_it): Call iterate_out_of_display_property only if we are
17159 popping after iteration over a string that came from a display
17160 property. Fix a typo in popping stretch info. Add an assertion
17161 for verifying that the iterator position is in sync with the bidi
17162 iterator.
17163 (handle_single_display_spec, get_overlay_strings_1)
17164 (push_display_prop): Fix initialization of paragraph direction for
17165 string when that of the parent object is not yet determined.
17166 (reseat_1): Call bidi_init_it to resync the bidi
17167 iterator with IT's position. (Bug#7616)
17168 (find_row_edges): If ROW->start.pos gives position
17169 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
17170 (handle_stop, back_to_previous_visible_line_start, reseat_1):
17171 Reset the from_disp_prop_p flag.
17172 (SAVE_IT, RESTORE_IT): New macros.
17173 (pos_visible_p, face_before_or_after_it_pos)

17571
17572 Remove unportable assumption about struct layout (Bug#8884).
17573 * alloc.c (mark_buffer):
17574 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
17575 (clone_per_buffer_values): Don't assume that
17576 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
17577 This isn't true in general, and it's particularly not true
17578 if Emacs is configured with --with-wide-int.
17579 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17580 New macros, used in the buffer.c change.
17581
17582 2011-07-05 Jan Djärv <jan.h.d@swipnet.se>
17583

17592 Move inside HAVE_XFT.
17593 (something_changed_gsettingsCB): Rename from something_changedCB.
17594 Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME
17595 also.
17596 (GCONF_TOOL_BAR_STYLE, GCONF_FONT_NAME): New defines.

17600 (parse_settings): Move check for font inside HAVE_XFT.
17601 (read_settings, apply_xft_settings): Add comment.
17602 (read_and_apply_settings): Add comment. Call map_tool_bar_style and
17603 store_tool_bar_style_changed. Move check for font inside HAVE_XFT and
17604 call store_font_name_changed.
17605 (xft_settings_event): Add comment.
17606 (init_gsettings): Add comment. Get values for GSETTINGS_TOOL_BAR_STYLE

17612 Add comment.
17613
17614 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
17615
17616 Random fixes. E.g., (random) never returned negative values.
17617 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17618 subseconds part to the entropy, as that's a bit more random.
17619 Prefer signed to unsigned, since the signedness doesn't matter and
17620 in general we prefer signed. When given a limit, use a
17621 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17622 latter isn't right if USE_2_TAGS_FOR_INTS.
17623 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17624 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17625
17626 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17627
17628 * textprop.c (text_property_stickiness):
17629 Obey Vtext_property_default_nonsticky.

17631 * w32fns.c (syms_of_w32fns):
17632 * xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.
17633
17634 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17635
17636 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17637 This is more efficient than Ffile_directory_p and avoids a minor race.
17638
17639 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17640
17641 * buffer.c (Foverlay_put): Say what the return value is
17642 (bug#7835).
17643
17644 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17645 is a directory before asking whether to use the file name
17646 (bug#7564).
17647 (barf_or_query_if_file_exists): Make the "File is a directory"
17648 error be more correct.
17649
17650 * fns.c (Frequire): Remove the mention of the .gz files, since
17651 that's installation-specific, but keep the mention of
17652 `get-load-suffixes'.
17653
17654 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17655
17656 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17658
17659 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
17660
17661 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
17662 (syms_of_gnutls): Remove duplicate DEFSYM for
17663 Qgnutls_bootprop_verify_hostname_error, an error for
17664 Qgnutls_bootprop_verify_error (which is no longer used).
17665
17666 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17667 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17668 Also (re)move comments that are misplaced or no longer relevant.
17669
17670 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17671
17672 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
17673
17674 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
17675

17682
17683 2011-07-03 Paul Eggert <eggert@cs.ucla.edu>
17684
17685 * xsettings.c (SYSTEM_FONT): Define only when used.
17686 No need to define when HAVE_GSETTINGS || !HAVE_XFT.
17687
17688 * keymap.c (access_keymap_1): Now static.
17689
17690 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
17691
17692 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
17693 leave any prefix arg for the up event (Bug#1586).
17694
17695 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>

17751 (emacs_settings_init, gsettings_obj): Remove.
17752 (something_changedCB): New function for HAVE_GSETTINGS.
17753 (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
17754 with value as argument.
17755 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
17756 g_settings_new (Bug#8967). Do not create gsettings_obj.
17757 Remove calls to g_settings_bind. Connect something_changedCB to
17758 "changed".
17759
17760 * xgselect.c: Add defined (HAVE_GSETTINGS).

17767 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
17768
17769 * eval.c (struct backtrace): Simplify and port the data structure.
17770 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17771 signed bit field, as this assumption is not portable and it makes
17772 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17773 "char debug_on_exit : 1" as this is not portable either; instead,
17774 use the portable "unsigned int debug_on_exit : 1". Remove unused
17775 member evalargs. Remove obsolete comments about cc bombing out.
17776
17777 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17812 clearly which files are directly included by each source file,
17813 and not through other includes.
17814
17815 2011-06-27 Martin Rudalics <rudalics@gmx.at>
17816
17817 * buffer.c (Qclone_number): Declare static and DEFSYM it.
17818 (sort_overlays, overlay_strings): When an overlay's clone number
17819 matches the window's clone number process the overlay even if
17820 the overlay's window property doesn't match the current window.
17821
17822 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.

17858
17859 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
17860 bidi_at_paragraph_end, since fast_looking_at doesn't like to be

17862
17863 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
17864
17865 * process.c (wait_reading_process_output): Bypass select if

17965 (read1): Check for integer overflow in radices, and in
17966 read-circle numbers.
17967 (read_escape): Avoid int overflow.
17968 (Fload, openp, read_buffer_size, read1)
17969 (substitute_object_recurse, read_vector, read_list, map_obarray):
17970 Use ptrdiff_t, not int, for sizes.
17971 (read1): Use EMACS_INT, not int, for sizes.
17972 Check for size overflow.
17973
17974 * image.c (cache_image): Check for size arithmetic overflow.
17975
17976 * lread.c: Integer overflow issues.
17977 (saved_doc_string_size, saved_doc_string_length)
17978 (prev_saved_doc_string_size, prev_saved_doc_string_length):
17979 Now ptrdiff_t, not int.
17980 (read1): Don't assume doc string length fits in int. Check for
17981 out-of-range doc string lengths.
17982 (read_list): Don't assume file position fits in int.
17983 (read_escape): Check for hex character overflow.
17984
17985 2011-06-22 Leo Liu <sdl.web@gmail.com>
17986
17987 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17988 Move to minibuffer.el.
17989
17990 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17991
17992 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17993 The following patches are for when GLYPH_DEBUG && !XASSERT.
17994 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17995 * dispnew.c (flush_stdout):
17996 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17997 Mark as externally visible.
17998 * dispnew.c (check_window_matrix_pointers): Now static.
17999 * dispnew.c (window_to_frame_vpos):
18000 * xfns.c (unwind_create_frame):
18001 * xterm.c (x_check_font): Remove unused local.
18002 * scroll.c (CHECK_BOUNDS):
18003 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18004 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18005 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18006 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18007 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18008 Now static.
18009 (debug_method_add): Use va_list and vsprintf rather than relying
18010 on undefined behavior with wrong number of arguments.
18011 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18012 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18013 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18014 since we're not interested in debugging glyphs with old libraries.
18015 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18016 GCC 4.6.0's static checking.
18017
18018 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18019
18020 Integer overflow and signedness fixes (Bug#8873).
18021 A few related buffer overrun fixes, too.
18022

18027 (x_bitmap_mask, x_allocate_bitmap_record)
18028 (x_create_bitmap_from_data, x_create_bitmap_from_file)
18029 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)

18033 (.bitmaps_last):
18034 * xfaces.c (load_pixmap):
18035 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18036 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18037 (.bitmaps_last, struct x_output.icon_bitmap):
18038 Use ptrdiff_t, not int, for bitmap indexes.
18039 (x_allocate_bitmap_record): Check for size overflow.
18040 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18041
18042 Use ptrdiff_t, not int, for overlay counts.
18043 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18044 * editfns.c (overlays_around, get_pos_property):
18045 * textprop.c (get_char_property_and_overlay):
18046 * xdisp.c (next_overlay_change, note_mouse_highlight):
18047 * xfaces.c (face_at_buffer_position):
18048 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18049 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18050 (Fnext_overlay_change, Fprevious_overlay_change)
18051 (mouse_face_overlay_overlaps, Foverlays_in):
18052 Use ptrdiff_t, not int, for sizes.
18053 (overlays_at, overlays_in): Check for size-calculation overflow.
18054
18055 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18056
18057 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18058 (x_session_initialize): Do not assume string length fits in int.
18059
18060 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18061 This is unlikely, but can occur if DPI is outlandish.
18062
18063 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18064 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18065
18066 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18067 * xrdb.c (magic_file_p, search_magic_path):
18068 Omit last arg SUFFIX; it was always 0. All callers changed.
18069 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18070
18071 * xfont.c (xfont_match): Avoid need for strlen.
18072
18073 * xfns.c: Don't assume strlen fits in int.
18074 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18075
18076 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18077 not unsigned long, as we prefer signed integers. All callers changed.
18078 Detect integer overflow in repeat count.
18079 (message_dolog): Don't assume print length fits in 39 bytes.
18080 (display_mode_element): Don't assume strlen fits in int.
18081
18082 * termcap.c: Don't assume sizes fit in int and never overflow.
18083 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18084 (gobble_line): Check for size-calculation overflow.
18085
18086 * minibuf.c (Fread_buffer):
18087 * lread.c (intern, intern_c_string):
18088 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18089 Don't assume string length fits in int.
18090
18091 * keyboard.c (parse_tool_bar_item):
18092 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18093
18094 * font.c: Don't assume string length fits in int.
18095 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18096 Use ptrdiff_t, not int.
18097 (font_intern_prop): Don't assume string length fits in int.

18099 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18100
18101 * filelock.c: Fix some buffer overrun and integer overflow issues.
18102 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18103 Reformulate so as not to need the command string.
18104 Invoke gzip -cd rather than gunzip, as it's more portable.
18105 (lock_info_type, lock_file_1, lock_file):
18106 Don't assume pid_t and time_t fit in unsigned long.
18107 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18108 (current_lock_owner): Prefer signed type for sizes.
18109 Use memcpy, not strncpy, where memcpy is what is really wanted.
18110 Don't assume (via atoi) that time_t and pid_t fit in int.
18111 Check for time_t and/or pid_t out of range, e.g., via a network share.
18112 Don't alloca where an auto var works fine.
18113
18114 * fileio.c: Fix some integer overflow issues.
18115 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18116 Don't assume string length fits in int.
18117 (directory_file_name): Don't assume string length fits in long.
18118 (make_temp_name): Don't assume pid fits in int, or that its print
18119 length is less than 20.
18120
18121 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18122
18123 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18124
18125 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18126
18127 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18128 We prefer signed integers, even for size calculations.
18129
18130 * emacs.c: Don't assume string length fits in 'int'.
18131 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18132 (main): Don't invoke strlen when not needed.
18133
18134 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18135 (XD_DEBUG_MESSAGE): Don't waste a byte.
18136
18137 * callproc.c (getenv_internal_1, getenv_internal)
18138 (Fgetenv_internal):
18139 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18140
18141 * lread.c (invalid_syntax): Omit length argument.
18142 All uses changed. This doesn't fix a bug, but it simplifies the
18143 code away from its former Hollerith-constant appearance, and it's
18144 one less 'int' to worry about when looking at integer-overflow issues.
18145 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18146
18147 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18148 This didn't break anything, but it didn't help either.
18149 It's confusing to put a bogus integer in a place where the actual
18150 value does not matter.
18151 (LIST_END_P): Remove unused macro and its bogus comment.
18152 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18153
18154 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18155 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18156 implementation.
18157 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18158 We prefer signed types, and the value cannot exceed the EMACS_INT
18159 range anyway (because otherwise the length would not be representable).
18160 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18161 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18162 This avoids a GCC warning when WIDE_EMACS_INT.
18163
18164 * indent.c (sane_tab_width): New function.
18165 (current_column, scan_for_column, Findent_to, position_indentation)
18166 (compute_motion): Use it. This is just for clarity.
18167 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18168
18169 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18170
18171 * lisp.h (lint_assume): New macro.
18172 * composite.c (composition_gstring_put_cache):
18173 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18174
18175 * editfns.c, insdel.c:
18176 Omit unnecessary forward decls, to simplify future changes.
18177
18178 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18179
18180 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18181
18182 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18183 Use much-faster test for byte-length change.
18184 Don't assume string byte-length fits in 'int'.
18185 Check that character arg fits in 'int'.
18186 (mapcar1): Declare byte as byte, for clarity.
18187
18188 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18189
18190 * fns.c (concat): Catch string overflow earlier.
18191 Do not rely on integer wraparound.
18192
18193 * dispextern.h (struct it.overlay_strings_charpos)
18194 (struct it.selective): Now EMACS_INT, not int.
18195 * xdisp.c (forward_to_next_line_start)
18196 (back_to_previous_visible_line_start)
18197 (reseat_at_next_visible_line_start, next_element_from_buffer):
18198 Don't arbitrarily truncate the value of 'selective' to int.
18199
18200 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18201
18202 * composite.c: Don't truncate sizes to 'int'.
18203 (composition_gstring_p, composition_reseat_it)
18204 (composition_adjust_point): Use EMACS_INT, not int.
18205 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18206 not EMACS_UINT, for indexes.
18207
18208 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18209
18210 * buffer.c: Include <verify.h>.
18211 (struct sortvec.priority, struct sortstr.priority):
18212 Now EMACS_INT, not int.
18213 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18214 (struct sortstr.size, record_overlay_string)
18215 (struct sortstrlist.size, struct sortlist.used):
18216 Don't truncate size to int.
18217 (record_overlay_string): Check for size-calculation overflow.
18218 (init_buffer_once): Check at compile-time, not run-time.
18219
18220 2011-06-22 Jim Meyering <meyering@redhat.com>
18221
18222 Don't leak an XBM-image-sized buffer
18223 * image.c (xbm_load): Free the image buffer after using it.
18224
18225 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18226
18227 Port to Sun C.
18228 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18229 that Sun C diagnosed.
18230 * fns.c (secure_hash): Fix pointer signedness issue.
18231 * intervals.c (static_offset_intervals): New function.
18232 (offset_intervals): Use it.
18233
18234 2011-06-21 Leo Liu <sdl.web@gmail.com>
18235
18236 * deps.mk (fns.o):
18237 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18238 sha512.h.
18239
18240 * fns.c (secure_hash): Rename from crypto_hash_function and change
18241 the first arg to accept symbols.
18242 (Fsecure_hash): New primitive.
18243 (syms_of_fns): New symbols.
18244
18245 2011-06-20 Deniz Dogan <deniz@dogan.se>
18246
18247 * process.c (Fset_process_buffer): Clarify return value in
18248 docstring.
18249
18250 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18251
18252 * dispnew.c (add_window_display_history): Use BVAR.
18253
18254 * xdisp.c (debug_method_add): Use BVAR.
18255 (check_window_end, dump_glyph_matrix, dump_glyph)
18256 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18257
18258 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18259 Likewise.
18260
18261 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18262 check till after the cache is created in init_frame_faces.
18263
18264 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18265
18266 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18267
18268 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18269
18270 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18271 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18272 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18273
18274 Improve buffer-overflow checking (Bug#8873).
18275 * fileio.c (Finsert_file_contents):
18276 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18277 Remove the old (too-loose) buffer overflow checks.
18278 They weren't needed, since make_gap checks for buffer overflow.
18279 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18280 The old code merely checked for Emacs fixnum overflow, and relied
18281 on undefined (wraparound) behavior. The new code avoids undefined
18282 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18283
18284 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18285 Tune. Don't use wider integers than needed. Don't use alloca.
18286 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18287
18288 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18289
18290 * insdel.c, lisp.h (buffer_overflow): New function.
18291 (insert_from_buffer_1, replace_range, replace_range_2):
18292 * insdel.c (make_gap_larger):
18293 * editfns.c (Finsert_char):
18294 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18295
18296 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18297
18298 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18299
18300 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18301
18302 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18303 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18304
18305 * fileio.c: Don't assume EMACS_INT fits in off_t.
18306 (emacs_lseek): New static function.
18307 (Finsert_file_contents, Fwrite_region): Use it.
18308 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18309
18310 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18311
18312 * fns.c: Don't overflow int when computing a list length.
18313 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18314 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18315 truncation on 64-bit hosts. Check for QUIT every
18316 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18317 faster and is responsive enough.
18318 (Flength): Report an error instead of overflowing an integer.
18319 (Fsafe_length): Return a float if the value is not representable
18320 as a fixnum. This shouldn't happen except in contrived situations.
18321 (Fnthcdr, Fsort): Don't assume list length fits in int.
18322 (Fcopy_sequence): Don't assume vector length fits in int.
18323
18324 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18325 (header_size, word_size): New constants.
18326 (allocate_vectorlike): Don't check size overflow here.
18327 (allocate_vector): Check it here instead, since this is the only
18328 caller of allocate_vectorlike that could cause overflow.
18329 Check that the new vector's length is representable as a fixnum.
18330
18331 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18332 The previous code was bogus. For example, next_almost_prime (32)
18333 returned 39, which is undesirable as it is a multiple of 3; and
18334 next_almost_prime (24) returned 25, which is a multiple of 5 so
18335 why was the code bothering to check for multiples of 7?
18336
18337 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18338
18339 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18340
18341 Variadic C functions now count arguments with ptrdiff_t.
18342 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18343 Back then I didn't know that the Emacs coding style prefers signed int.
18344 Also, in the meantime I found a few more instances where arguments
18345 were being counted with int, which may truncate counts on 64-bit
18346 machines, or EMACS_INT, which may be unnecessarily wide.
18347 * lisp.h (struct Lisp_Subr.function.aMANY)
18348 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18349 Arg counts are now ptrdiff_t, not size_t.
18350 All variadic functions and their callers changed accordingly.
18351 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18352 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18353 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18354 * callint.c (Fcall_interactively): Check arg count for overflow,
18355 to avoid potential buffer overrun. Use signed char, not 'int',
18356 for 'varies' array, so that we needn't bother to check its size
18357 calculation for overflow.
18358 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18359 * eval.c (apply_lambda):
18360 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18361 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18362 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18363
18364 * callint.c (Fcall_interactively): Don't use index var as event count.
18365
18366 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18367 * mem-limits.h (SIZE): Remove; no longer used.
18368
18369 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18370
18371 Remove unnecessary casts.
18372 * xterm.c (x_term_init):
18373 * xfns.c (x_set_border_pixel):
18374 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18375 These aren't needed now that we assume ANSI C.
18376
18377 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18378 It's more likely to cause problems (due to unsigned overflow)
18379 than to cure them.
18380
18381 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18382
18383 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18384
18385 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18386
18387 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18388
18389 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18390
18391 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18392
18393 GLYPH_CODE_FACE returns EMACS_INT, not int.
18394 * dispextern.h (merge_faces):
18395 * xfaces.c (merge_faces):
18396 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18397 Don't assume EMACS_INT fits in int.
18398
18399 * character.h (CHAR_VALID_P): Remove unused parameter.
18400 * fontset.c, lisp.h, xdisp.c: All uses changed.
18401
18402 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18403
18404 * fns.c (concat): Minor tuning based on overflow analysis.
18405 This doesn't fix any bugs. Use int to hold character, instead
18406 of constantly refetching from Emacs object. Use XFASTINT, not
18407 XINT, for value known to be a character. Don't bother comparing
18408 a single byte to 0400, as it's always less.
18409
18410 * floatfns.c (Fexpt):
18411 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18412
18413 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18414 for characters.
18415
18416 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18417
18418 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18419 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18420 incorrectly succeed when S was a string, because 4294967386 was
18421 truncated before it was used.
18422
18423 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18424 Otherwise, an out-of-range integer could cause undefined behavior
18425 on a 64-bit host.
18426
18427 * composite.c: Use int, not EMACS_INT, for characters.
18428 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18429 EMACS_INT, for values that are known to be in character range.
18430 This doesn't fix any bugs but is the usual style inside Emacs and
18431 may generate better code on 32-bit machines.
18432
18433 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18434 This is for reasons similar to the recent CHAR_STRING fix.
18435 * charset.c (Fencode_char): Check that character arg is actually
18436 a character. Pass an int to ENCODE_CHAR.
18437 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18438 wider than 'int', as a compile-time check to prevent future regressions
18439 in this area.
18440
18441 * character.c (char_string): Remove unnecessary casts.
18442
18443 Make sure a 64-bit char is never passed to CHAR_STRING.
18444 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18445 by silently ignoring the top 32 bits, allowing some values
18446 that were far too large to be valid characters.
18447 * character.h: Include <verify.h>.
18448 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18449 arguments are no wider than unsigned, as a compile-time check
18450 to prevent future regressions in this area.
18451 * data.c (Faset):
18452 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18453 (Fsubst_char_in_region):
18454 * fns.c (concat):
18455 * xdisp.c (decode_mode_spec_coding):
18456 Adjust to CHAR_STRING's new requirement.
18457 * editfns.c (Finsert_char, Fsubst_char_in_region):
18458 * fns.c (concat): Check that character args are actually
18459 characters. Without this test, these functions did the wrong
18460 thing with wildly out-of-range values on 64-bit hosts.
18461
18462 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18463 These casts should not be needed on 32-bit hosts, either.
18464 * keyboard.c (read_char):
18465 * lread.c (Fload): Remove casts to unsigned.
18466
18467 * lisp.h (UNSIGNED_CMP): New macro.
18468 This fixes comparison bugs on 64-bit hosts.
18469 (ASCII_CHAR_P): Use it.
18470 * casefiddle.c (casify_object):
18471 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18472 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18473 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18474 * dispextern.h (FACE_FROM_ID):
18475 * keyboard.c (read_char): Use UNSIGNED_CMP.
18476
18477 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18478 not to EMACS_INT, to avoid GCC warning.
18479
18480 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18481
18482 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18483 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18484 isn't needed on 32-bit machines.
18485
18486 * buffer.c (Fgenerate_new_buffer_name):
18487 Use EMACS_INT for count, not int.
18488 (advance_to_char_boundary): Return EMACS_INT, not int.
18489
18490 * data.c (Qcompiled_function): Now static.
18491
18492 * window.c (window_body_lines): Now static.
18493
18494 * image.c (gif_load): Rename local to avoid shadowing.
18495
18496 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18497 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18498 * alloc.c (make_save_value): Integer argument is now of type
18499 ptrdiff_t, not int.
18500 (mark_object): Use ptrdiff_t, not int.
18501 * lisp.h (pD): New macro.
18502 * print.c (print_object): Use it.
18503
18504 * alloc.c: Use EMACS_INT, not int, to count objects.
18505 (total_conses, total_markers, total_symbols, total_vector_size)
18506 (total_free_conses, total_free_markers, total_free_symbols)
18507 (total_free_floats, total_floats, total_free_intervals)
18508 (total_intervals, total_strings, total_free_strings):
18509 Now EMACS_INT, not int. All uses changed.
18510 (Fgarbage_collect): Compute overall total using a double, so that
18511 integer overflow is less likely to be a problem. Check for overflow
18512 when converting back to an integer.
18513 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18514 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18515 These were 'int' variables that could overflow on 64-bit hosts;
18516 they were never used, so remove them instead of repairing them.
18517 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18518 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18519 Previously, this ceilinged at INT_MAX, but that doesn't work on
18520 64-bit machines.
18521 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18522
18523 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18524 (allocate_vectorlike): Check for ptrdiff_t overflow.
18525 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18526 when a (possibly-narrower) signed value would do just as well.
18527 We prefer using signed arithmetic, to avoid comparison confusion.
18528
18529 * alloc.c: Catch some string size overflows that we were missing.
18530 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18531 for convenience in STRING_BYTES_MAX.
18532 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18533 The definition here is exact; the one in lisp.h was approximate.
18534 (allocate_string_data): Check for string overflow. This catches
18535 some instances we weren't catching before. Also, it catches
18536 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18537 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18538 and ptrdiff_t and EMACS_INT are both 64 bits.
18539
18540 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18541 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18542 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18543
18544 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18545
18546 * alloc.c (Fmake_string): Check for out-of-range init.
18547
18548 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18549
18550 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18551
18552 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18553
18554 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18555 xg_get_default_scrollbar_width.
18556
18557 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18558 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18559 (style_changed_cb): Call update_theme_scrollbar_width and call
18560 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18561 all frames (Bug#8505).
18562 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18563 Call gtk_window_set_resizable if HAVE_GTK3.
18564 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18565 and height if HAVE_GTK3 (Bug#8505).
18566 (scroll_bar_width_for_theme): New variable.
18567 (update_theme_scrollbar_width): New function.
18568 (xg_get_default_scrollbar_width): Move code to
18569 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18570 (xg_initialize): Call update_theme_scrollbar_width.
18571
18572 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18573
18574 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18575
18576 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18577
18578 * frame.c (make_frame): Call other_buffer_safely instead of
18579 other_buffer.
18580
18581 * window.c (temp_output_buffer_show): Call display_buffer with
18582 second argument Vtemp_buffer_show_specifiers and reset latter
18583 immediately after the call.
18584 (Vtemp_buffer_show_specifiers): New variable.
18585 (auto_window_vscroll_p, next_screen_context_lines)
18586 (Vscroll_preserve_screen_position): Remove leading asterisks from
18587 doc-strings.
18588

18598 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18599 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18600 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18601 if HAVE_GPM.
18602 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18603 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18604 Define only if HAVE_GPM.
18605 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18606 (update_hints_inhibit): Remove; never set. All uses removed.
18607 * widgetprv.h (emacsFrameClassRec): Remove decl.
18608 * window.c (delete_deletable_window): Now returns void, since it
18609 wasn't returning anything.
18610 (compare_window_configurations): Remove unused locals.
18611 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18612 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18613 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18614 the same widths as pointers. This follows up on the 2011-05-06 patch.
18615 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18616 * xterm.h: Likewise.

18628
18629 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18630
18631 * window.c (delete_deletable_window): Re-add.
18632 (Fset_window_configuration): Rewrite to handle dead buffers and
18633 consequently deletable windows.
18634 (window_tree, Fwindow_tree): Remove. Supply functionality in
18635 window.el.
18636 (compare_window_configurations): Simplify code.
18637

18639
18640 * image.c (imagemagick_load_image): Fix type mismatch.
18641 (Fimagemagick_types): Likewise.
18642
18643 * window.h (replace_buffer_in_windows): Declare.
18644
18645 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18646
18647 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18648 Qclone_number. Remove external declaration of Qdelete_window.
18649 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18650 code.
18651 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18652 Run Qbuffer_list_update_hook if allowed.
18653 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18654 buffer list implementation.

18656 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18657 calls to replace_buffer_in_windows and

18659 if allowed.
18660 (record_buffer): Inhibit quitting and rewrite using quittable
18661 functions. Run Qbuffer_list_update_hook if allowed.
18662 (Frecord_buffer, Funrecord_buffer): New functions.
18663 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18664 Move switch-to-buffer to window.el.

19145 property that is a list to be consistent with handle_display_spec.
19146 (handle_display_spec): New function, refactored from the
19147 last portion of handle_display_prop.
19148 (compute_display_string_pos): Accept additional argument
19149 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19150 value of a `display' property is a "replacing spec".
19151 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19152 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19153 the display property, but just return a value indicating whether
19154 the display property will replace the characters it covers.
19155 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19156 frame_window_p members of struct bidi_it.
19157 (compute_display_string_pos, compute_display_string_end):
19158 New functions.
19159 (push_it): Accept second argument POSITION, where pop_it should
19160 jump to continue iteration.
19161 (reseat_1): Initialize bidi_it.disp_pos.
19162
19163 * keyboard.c (adjust_point_for_property): Adjust the call to
19164 display_prop_intangible_p to its new signature.
19165
19166 * dispextern.h (struct bidi_it): New member frame_window_p.
19167 (bidi_init_it): Update prototypes.
19168 (display_prop_intangible_p): Update prototype.
19169 (compute_display_string_pos, compute_display_string_end):
19170 Declare prototypes.
19171 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19172 EMACS_INT.
19173
19174 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19175
19176 Malloc failure behavior now depends on size of allocation.
19177 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19178 * lisp.h: Change signatures accordingly.
19179 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19180 All callers changed. (Bug#8762)
19181
19182 * gnutls.c: Use Emacs's memory allocators.
19183 Without this change, the gnutls library would invoke malloc etc.
19184 directly, which causes problems on non-SYNC_INPUT hosts, and which
19185 runs afoul of improving memory_full behavior. (Bug#8761)
19186 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19187 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19188 xfree instead of the default malloc, realloc, free.
19189 (Fgnutls_boot): No need to check for memory allocation failure,
19190 since xmalloc does that for us.
19191
19192 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19193 * category.c (hash_get_category_set):
19194 * ccl.c (ccl_driver):
19195 * charset.c (Fdefine_charset_internal):
19196 * charset.h (struct charset.hash_index):
19197 * composite.c (get_composition_id, gstring_lookup_cache)
19198 (composition_gstring_put_cache):
19199 * composite.h (struct composition.hash_index):
19200 * dispextern.h (struct image.hash):
19201 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19202 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
19203 (hashfn_equal, hashfn_user_defined, make_hash_table)

19205 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19206 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19207 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19208 * image.c (make_image, search_image_cache, lookup_image)
19209 (xpm_put_color_table_h):
19210 * lisp.h (struct Lisp_Hash_Table):
19211 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19212 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19213 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19214 * alloc.c (allocate_vectorlike):
19215 Check for overflow in vector size calculations.
19216 * ccl.c (ccl_driver):
19217 Check for overflow when converting EMACS_INT to int.
19218 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19219 need to be updated by these changes.
19220 * fns.c (make_hash_table, maybe_resize_hash_table):
19221 Check for integer overflow with large hash tables.
19222 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19223 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19224 (SXHASH_REDUCE): New macro.
19225 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19226 Use it instead of discarding useful hash info with large hash values.
19227 (sxhash_float): New function.
19228 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19229 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19230 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19231 Rewrite to use FIXNUM_BITS, as this simplifies things.
19232 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19233 Adjust signatures to match updated version of code.
19234 (consing_since_gc): Now EMACS_INT, since a single hash table can
19235 use more than INT_MAX bytes.
19236
19237 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19238
19239 Make it possible to build with GCC-4.6+ -O2 -flto.
19240
19241 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19242
19243 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19244
19245 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19246 Call minibuffer-inactive-mode.
19247
19248 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19249
19250 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19251 Update dependencies.
19252
19253 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19254
19255 * data.c (init_data): Remove code for UTS, this system is not
19256 supported anymore.
19257
19258 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19259
19260 Don't force ./temacs to start in terminal mode.
19261
19262 * frame.c (make_initial_frame): Initialize faces in all cases, not
19263 only when CANNOT_DUMP is defined.
19264 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19265
19266 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19267
19268 * dispnew.c (add_window_display_history): Use const for the string
19269 pointer. Remove declaration, not needed.
19270
19271 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19272
19273 Use 'inline', not 'INLINE'.
19274 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19275 * alloc.c, fontset.c (INLINE): Remove.
19276 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19277 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19278 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19279 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19280 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19281
19282 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19283
19284 Make it possible to run ./temacs.
19285
19286 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19287 syms_of_callproc does the same thing. Remove test for
19288 "initialized", do it in the caller.
19289 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19290
19291 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19292
19293 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19294 (read_minibuf): Use get_minibuffer.
19295 (syms_of_minibuf): Use DEFSYM.
19296 (Qmetadata): New var.
19297 * data.c (Qbuffer): Don't make it static.
19298 (syms_of_data): Use DEFSYM.
19299
19300 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19301
19302 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19303 (CCL_CODE_MIN): New macro.
19304
19305 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19306
19307 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19308
19309 * eval.c (Qdebug): Now static.
19310 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19311 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19312 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19313
19314 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19315
19316 * image.c: Various fixes to ImageMagick code comments.
19317 (Fimagemagick_types): Doc fix.
19318
19319 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19320
19321 Minor fixes prompted by GCC 4.6.0 warnings.
19322
19323 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19324
19325 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19326 (x_clipboard_manager_save_all): Move extern decl to ...
19327 * xterm.h: ... here, so that it can be checked for consistency.
19328
19329 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19330
19331 * xselect.c (x_clipboard_manager_save_frame)
19332 (x_clipboard_manager_save_all): New functions.
19333 (Fx_clipboard_manager_save): Lisp function deleted.
19334
19335 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19336 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19337
19338 * xterm.h: Update prototype.
19339
19340 2011-05-28 William Xu <william.xwl@gmail.com>
19341
19342 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19343 exiting (Bug#8239).
19344
19345 2011-05-28 Jim Meyering <meyering@redhat.com>
19346
19347 Avoid a sign-extension bug in crypto_hash_function.
19348 * fns.c (to_uchar): Define.
19349 (crypto_hash_function): Use it to convert some newly-signed
19350 variables to unsigned, to avoid sign-extension bugs. For example,
19351 without this change, (md5 "truc") would evaluate to
19352 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19353 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19354 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19355
19356 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19357
19358 Integer overflow fixes.
19359
19360 * dbusbind.c: Serial number integer overflow fixes.
19361 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19362 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19363 to hold a serial number that is too large for a fixnum.
19364 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19365 Check for serial numbers out of range. Decode any serial number
19366 that was so large that it became a float. (Bug#8722)
19367
19368 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19369 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19370 Use XFASTINT rather than XUINT when numbers are nonnegative.
19371 (xd_append_arg, Fdbus_method_return_internal):
19372 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19373 arguments, check that Lisp number is nonnegative, rather than
19374 silently wrapping negative numbers around. (Bug#8722)
19375 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19376 (Bug#8722)
19377
19378 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19379
19380 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19381
19382 ccl: Add integer overflow checks.
19383 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19384 (IN_INT_RANGE): New macros.
19385 (ccl_driver): Use them to check for integer overflow when
19386 decoding a CCL program. Many of the new checks are whether XINT (x)
19387 fits in int; it doesn't always, on 64-bit hosts. The new version
19388 doesn't catch all possible integer overflows, but it's an
19389 improvement. (Bug#8719)
19390
19391 * alloc.c (make_event_array): Use XINT, not XUINT.
19392 There's no need for unsigned here.
19393
19394 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19395 This follows up to the 2011-05-06 change that substituted uintptr_t
19396 for EMACS_INT. This case wasn't caught back then.
19397
19398 Rework Fformat to avoid integer overflow issues.
19399 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19400 now (part of C89). Include <verify.h>.
19401 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19402 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19403 (Fformat): Avoid the prepass trying to compute sizes; it was only
19404 approximate and thus did not catch overflow reliably. Instead, walk
19405 through the format just once, formatting and computing sizes as we go,
19406 checking for integer overflow at every step, and allocating a larger
19407 buffer as needed. Keep track separately whether the format is
19408 multibyte. Keep only the most-recently calculated precision, rather
19409 than them all. Record whether each argument has been converted to
19410 string. Use EMACS_INT, not int, for byte and char and arg counts.
19411 Support field widths and precisions larger than INT_MAX. Avoid
19412 sprintf's undefined behavior with conversion specifications such as %#d
19413 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19414 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19415 formatting out-of-range floating point numbers with int
19416 formats. (Bug#8668)
19417
19418 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19419
19420 * data.c: Avoid integer truncation in expressions involving floats.
19421 * data.c: Include <intprops.h>.
19422 (arith_driver): When there's an integer overflow in an expression
19423 involving floating point, convert the integers to floating point
19424 so that the resulting value does not suffer from catastrophic
19425 integer truncation. For example, on a 64-bit host (* 4
19426 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19427 Do not rely on undefined behavior after integer overflow.
19428
19429 merge count_size_as_multibyte, parse_str_to_multibyte
19430 * character.c, character.h (count_size_as_multibyte):
19431 Rename from parse_str_to_multibyte; all uses changed.
19432 Check for integer overflow.
19433 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19434 since it's now a duplicate of the other. This is more of
19435 a character than a buffer op, so better that it's in character.c.
19436 * fns.c, print.c: Adjust to above changes.
19437
19438 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19439
19440 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19441
19442 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19443
19444 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19445 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19446 (x_clipboard_manager_save): Now static.
19447 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19448
19449 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19450 (crypto_hash_function): Now static.
19451 Fix pointer signedness problems. Avoid unnecessary initializations.
19452
19453 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19454
19455 * termhooks.h (Vselection_alist): Make it terminal-local.
19456
19457 * terminal.c (create_terminal): Initialize it.
19458
19459 * xselect.c: Support for clipboard managers.
19460 (Vselection_alist): Move to termhooks.h as terminal-local var.
19461 (LOCAL_SELECTION): New macro.
19462 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19463 (symbol_to_x_atom): Remove gratuitous arg.
19464 (x_handle_selection_request, lisp_data_to_selection_data)
19465 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19466 (x_own_selection, x_get_local_selection, x_convert_selection):
19467 New arg, specifying work frame. Use terminal-local Vselection_alist.
19468 (some_frame_on_display): Delete unused function.
19469 (Fx_own_selection_internal, Fx_get_selection_internal)
19470 (Fx_disown_selection_internal, Fx_selection_owner_p)
19471 (Fx_selection_exists_p): New optional frame arg.
19472 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19473 (x_handle_selection_clear): Don't treat other terminals with the
19474 same keyboard specially. Use the terminal-local Vselection_alist.
19475 (x_clear_frame_selections): Use Frun_hook_with_args.
19476
19477 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19478
19479 * xterm.h: Add support for those atoms.
19480
19481 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19482
19483 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19484 (converted_selections, conversion_fail_tag): New global variables.
19485 (x_selection_request_lisp_error): Free the above.
19486 (x_get_local_selection): Remove unnecessary code.
19487 (x_reply_selection_request): Args changed; handle arbitrary array
19488 of converted selections stored in converted_selections.
19489 Separate the XChangeProperty and SelectionNotify steps.
19490 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19491 (x_convert_selection): New function.
19492 (x_handle_selection_event): Simplify.
19493 (x_get_foreign_selection): Don't ignore incoming requests while
19494 waiting for an answer; this will fail when we implement
19495 SAVE_TARGETS, and seems unnecessary anyway.
19496 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19497 (Vx_sent_selection_functions): Doc fix.
19498
19499 2011-05-26 Leo Liu <sdl.web@gmail.com>
19500
19501 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)

19506
19507 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19508 for fringe update if it has periodic bitmap.
19509 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19510 and fringe_bitmap_periodic_p.
19511
19512 * fringe.c (get_fringe_bitmap_data): New function.
19513 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19514 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19515 row. Mark glyph row for fringe update if periodicity changed.
19516
19517 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19518 for fringe update unless it has periodic bitmap.
19519

19527 * deps.mk (fns.o):
19528 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19529
19530 * fns.c (crypto_hash_function, Fsha1): New function.
19531 (Fmd5): Use crypto_hash_function.
19532 (syms_of_fns): Add Ssha1.
19533
19534 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19535
19536 * gnutls.c: Remove unused macros.
19537 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19538 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19539 Remove macros that are defined and never used.
19540 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19541
19542 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19543
19544 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19545 (Fx_get_selection_internal): Minor cleanup.
19546 (Fx_own_selection_internal): Rename arguments for consistency with
19547 select.el.
19548
19549 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19550
19551 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19552
19553 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19554
19555 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19556
19557 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19558
19559 * dispnew.c (scrolling_window): Don't exclude the case that the
19560 last enabled row in the desired matrix touches the bottom boundary.
19561
19562 2011-05-21 Glenn Morris <rgm@gnu.org>
19563
19564 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19565 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19566 and add some more files.
19567
19568 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19569
19570 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19571 report_file_error introduced by the change from 2011-05-07.
19572
19573 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19574
19575 * systime.h (Time): Define only if emacs is defined.
19576 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19577 where the include path doesn't have X11/X.h by default. See
19578 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19579
19580 2011-05-20 Kenichi Handa <handa@m17n.org>
19581
19582 * composite.c (find_automatic_composition): Fix previous change.
19583
19584 2011-05-20 Glenn Morris <rgm@gnu.org>
19585
19586 * lisp.mk: New file, split from Makefile.in.
19587 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19588 (shortlisp): Remove.
19589 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19590
19591 2011-05-19 Glenn Morris <rgm@gnu.org>
19592
19593 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19594 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19595 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19596 (lisp): Set the order to that of loadup.el.
19597 (shortlisp): Make it a copy of $lisp.
19598 (SOME_MACHINE_LISP): Remove.
19599 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19600 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19601
19602 2011-05-18 Kenichi Handa <handa@m17n.org>
19603
19604 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19605 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19606 (find_automatic_composition): Mostly rewrite for efficiency.
19607
19608 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19609
19610 * makefile.w32-in: Update dependencies.
19611
19612 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19613
19614 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19615 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19616
19617 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19618
19619 Fix some integer overflow issues, such as string length overflow.
19620
19621 * insdel.c (count_size_as_multibyte): Check for string overflow.
19622
19623 * character.c (lisp_string_width): Check for string overflow.
19624 Use EMACS_INT, not int, for string indexes and lengths; in
19625 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19626 the resulting string length overflows an EMACS_INT; instead,
19627 report a string overflow if no precision given. When checking for
19628 precision exhaustion, use a check that cannot possibly have
19629 integer overflow. (Bug#8675)
19630 * character.h (lisp_string_width): Adjust to new signature.
19631
19632 * alloc.c (string_overflow): New function.
19633 (Fmake_string): Use it. This doesn't change behavior, but saves
19634 a few bytes and will simplify future changes.
19635 * character.c (string_escape_byte8): Likewise.
19636 * lisp.h (string_overflow): New decl.
19637
19638 Fixups, following up to the user-interface timestamp change.
19639 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19640 for UI timestamps, instead of unsigned long.
19641 * msdos.c (mouse_get_pos): Likewise.
19642 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19643 * w32gui.h (Time): Define by including "systime.h" rather than by
19644 declaring it ourselves. (Bug#8664)
19645
19646 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19647 * image.c (clear_image_cache): Likewise.
19648
19649 * term.c (term_mouse_position): Don't assume time_t wraparound.
19650
19651 Be more systematic about user-interface timestamps.
19652 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19653 and sometimes 'EMACS_UINT', to represent these timestamps.
19654 This change causes it to use 'Time' uniformly, as that's what X uses.
19655 This makes the code easier to follow, and makes it easier to catch
19656 integer overflow bugs such as Bug#8664.
19657 * frame.c (Fmouse_position, Fmouse_pixel_position):
19658 Use Time, not unsigned long, for user-interface timestamps.
19659 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19660 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19661 * keyboard.h (last_event_timestamp): Likewise.
19662 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19663 * menu.h (xmenu_show): Likewise.
19664 * term.c (term_mouse_position): Likewise.
19665 * termhooks.h (struct input_event.timestamp): Likewise.
19666 (struct terminal.mouse_position_hook): Likewise.
19667 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19668 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19669 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19670 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19671 what it was before.
19672 * menu.h, termhooks.h: Include "systime.h", for Time.
19673
19674 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19675 Don't assume that the difference between two unsigned long values
19676 can fit into an integer. At this point, we know button_down_time
19677 <= event->timestamp, so the difference must be nonnegative, so
19678 there's no need to cast the result if double-click-time is
19679 nonnegative, as it should be; check that it's nonnegative, just in
19680 case. This bug is triggered when events are more than 2**31 ms
19681 apart (about 25 days). (Bug#8664)
19682
19683 * xselect.c (last_event_timestamp): Remove duplicate decl.
19684 (x_own_selection): Remove needless cast to unsigned long.
19685
19686 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19687 that always fit in int. Use a sentinel instead of a counter, to
19688 avoid a temp and to allay GCC's concerns about possible int overflow.
19689 * frame.h (struct frame): Use int for menu_bar_items_used
19690 instead of EMACS_INT, since it always fits in int.
19691
19692 * menu.c (grow_menu_items): Check for int overflow.
19693
19694 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19695
19696 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19697 Before, the code was not consistent. These values cannot exceed
19698 2**31 - 1 so there's no need to make them unsigned.
19699 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19700 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19701 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19702 as modifiers.
19703 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19704
19705 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19706 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19707 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19708 presumably because the widths might not match.
19709
19710 * window.c (size_window): Avoid needless test at loop start.
19711
19712 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19713
19714 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19715
19716 2011-05-12 Drew Adams <drew.adams@oracle.com>
19717
19718 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19719
19720 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19721
19722 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19723 `width' to `bar_area_x' and `bar_area_width', respectively.
19724 (x_scroll_run): Take account of fringe background extension.
19725
19726 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19727 Rename local vars `left' and `width' to `bar_area_x' and
19728 `bar_area_width', respectively.
19729 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19730 background extension.
19731
19732 2011-05-10 Jim Meyering <meyering@redhat.com>
19733
19734 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19735
19736 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19737
19738 * image.c (Finit_image_library): Return t for built-in image types,
19739 like pbm and xbm. (Bug#8640)
19740
19741 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19742
19743 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19744
19745 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19746
19747 * w32console.c (Fset_screen_color): Doc fix.
19748 (Fget_screen_color): New function.
19749 (syms_of_ntterm): Defsubr it.
19750
19751 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19752 unlink the temporary file if Fcall_process didn't create it in the
19753 first place.
19754 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19755 child process will be redirected to a file specified with `:file'.
19756 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19757 cue to call_process_cleanup not to close that handle.
19758
19759 2011-05-07 Ben Key <bkey76@gmail.com>
19760
19761 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19762 one of two shell specific rules, either bootstrap-temacs-CMD or
19763 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19764 to the previous implementation of the bootstrap-temacs rule.
19765 The bootstrap-temacs-CMD rule is similar to the previous
19766 implementation of the bootstrap-temacs rule except that it
19767 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19768 variable.
19769
19770 These changes, along with some changes to nt/configure.bat,
19771 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19772 earlier fix to add support for --cflags and --ldflags options
19773 that include quotes so that it works whether make uses cmd or
19774 sh as the shell.
19775
19776 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19777
19778 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19779 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19780 is a constant.
19781 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19782 a string. Handle both cases.
19783 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19784 (Fdbus_register_method): Use Qinvalid_function.
19785
19786 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19787
19788 * makefile.w32-in: Update dependencies.
19789 (LISP_H): Add inttypes.h and stdin.h.
19790 (PROCESS_H): Add unistd.h.
19791
19792 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19793
19794 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19795 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19796
19797 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19798
19799 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19800
19801 * term.c (vfatal): Remove stray call to va_end.
19802 It's not needed and the C Standard doesn't allow it here anyway.
19803
19804 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19805 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19806
19807 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19808 bytes.
19809
19810 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19811
19812 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19813
19814 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19815
19816 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19817
19818 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19819
19820 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19821 * charset.c (Fdefine_charset_internal): Don't initialize
19822 charset.code_space[15]. The value was garbage, on hosts with
19823 32-bit int (Bug#8600).
19824
19825 * lread.c (read_integer): Be more consistent with string-to-number.
19826 Use string_to_number to do the actual conversion; this avoids
19827 rounding errors and fixes some other screwups. Without this fix,
19828 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19829 (digit_to_number): Move earlier, for benefit of read_integer.
19830 Return -1 if the digit is out of range for the base, -2 if it is
19831 not a digit in any supported base. (Bug#8602)
19832
19833 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19834
19835 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19836 to match comment at start of function. This also removes a
19837 GCC warning about overflow in a 32+64-bit port.
19838
19839 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19840
19841 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19842 Reported by Stefan Monnier in
19843 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19844 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19845 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19846
19847 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19848 (EMACS_UINTPTR): Likewise, with uintptr_t.
19849
19850 * lisp.h: Prefer 64-bit EMACS_INT if available.
19851 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19852 on 32-bit hosts that have 64-bit int, so that they can access
19853 large files.
19854 However, temporarily disable this change unless the temporary
19855 symbol WIDE_EMACS_INT is defined.
19856
19857 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19858
19859 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19860 This removes an assumption that EMACS_INT and long are the same
19861 width as pointers. The assumption is true for Emacs porting targets
19862 now, but we want to make other targets possible.
19863 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19864 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19865 In the rest of the code, change types of integers that hold casted
19866 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19867 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19868 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19869 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19870 No need to cast type when ORing.
19871 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19872 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19873 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19874 assume EMACS_INT is the same width as char *.
19875 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19876 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19877 Remove no-longer-needed casts.
19878 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19879 (xg_tool_bar_help_callback, xg_make_tool_item):
19880 Use EMACS_INTPTR to hold an integer
19881 that will be cast to void *; this can avoid a GCC warning
19882 if EMACS_INT is not the same width as void *.
19883 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19884 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19885 (current_message_1, set_message_1):
19886 Use a local to convert to proper width without a cast.
19887 * xmenu.c (dialog_selection_callback): Likewise.
19888
19889 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19890 Also, don't assume VALBITS / RAND_BITS is less than 5,
19891 and don't rely on undefined behavior when shifting a 1 left into
19892 the sign bit.
19893 * lisp.h (get_random): Change signature to match.
19894
19895 * lread.c (hash_string): Use size_t, not int, for hash computation.
19896 Normally we prefer signed values; but hashing is special, because
19897 it's better to use unsigned division on hash table sizes so that
19898 the remainder is nonnegative. Also, size_t is the natural width
19899 for hashing into memory. The previous code used 'int', which doesn't
19900 retain enough info to hash well into very large tables.
19901 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19902
19903 * dbusbind.c: Don't possibly lose pointer info when converting.
19904 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19905 Use XPNTR rather than XHASH, so that the high-order bits of
19906 the pointer aren't lost when converting through void *.
19907
19908 * eval.c (Fautoload): Don't double-shift a pointer.
19909
19910 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19911
19912 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19913
19914 * gnutls.c (DEF_GNUTLS_FN):

20081
20082 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20115 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20116
20117 Improve `doprnt' and its usage. (Bug#8545)
20118 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20119 `format_end'. Remove support for %l as a conversion specifier.

20121 is used. Update the commentary.
20122
20123 * eval.c (verror): Simplify calculation of size_t.
20124
20125 * coding.c (Ffind_operation_coding_system): Fix diagnostic error

20128 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20129
20130 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20131 change.
20132
20133 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20134
20135 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20136 This makes this file independent of the recent pseudovector change.
20137
20138 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20139
20140 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20141
20142 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20143 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20144 Remove unused local.
20145 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20146
20147 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20148 GCC 4.6.0 optimizes based on type-based alias analysis.
20149 For example, if b is of type struct buffer * and v of type struct
20150 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20151 != &v->size, and therefore "v->size = 1; b->size = 2; return
20152 v->size;" must therefore return 1. This assumption is incorrect
20153 for Emacs, since it type-puns struct Lisp_Vector * with many other
20154 types. To fix this problem, this patch adds a new type struct
20155 vectorlike_header that documents the constraints on layout of vectors
20156 and pseudovectors, and helps optimizing compilers not get fooled
20157 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20158 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20159 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20160 the size member.
20161 (XSETPVECTYPE): Rewrite in terms of new macro.
20162 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20163 This is a bit clearer, and further avoids the possibility of
20164 undesirable aliasing.
20165 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20166 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20167 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20168 since Lisp_Subr is a special case (no "next" field).
20169 (ASIZE): Now uses header.size rather than size.
20170 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20171 to avoid the hassle of writing XVECTOR (foo)->header.size.
20172 (struct vectorlike_header): New type.
20173 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20174 object, to help avoid aliasing.
20175 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20176 (SUBRP): Likewise, since Lisp_Subr is a special case.
20177 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20178 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20179 (struct Lisp_Hash_Table): Combine first two members into a single
20180 struct vectorlike_header member. All uses of "size" and "next" members
20181 changed to be "header.size" and "header.next".
20182 * buffer.h (struct buffer): Likewise.
20183 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20184 * frame.h (struct frame): Likewise.
20185 * process.h (struct Lisp_Process): Likewise.
20186 * termhooks.h (struct terminal): Likewise.
20187 * window.c (struct save_window_data, struct saved_window): Likewise.
20188 * window.h (struct window): Likewise.
20189 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20190 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20191 * buffer.c (init_buffer_once): Likewise.
20192 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20193 special case.
20194 * process.c (Fformat_network_address): Use local var for size,
20195 for brevity.
20196
20197 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20198
20199 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20200 * data.c (atof): Remove decl; no longer used or needed.
20201 (digit_to_number): Move to lread.c.
20202 (Fstring_to_number): Use new string_to_number function, to be
20203 consistent with how the Lisp reader treats infinities and NaNs.
20204 Do not assume that floating-point numbers represent EMACS_INT
20205 without losing information; this is not true on most 64-bit hosts.
20206 Avoid double-rounding errors, by insisting on integers when
20207 parsing non-base-10 numbers, as the documentation specifies.
20208 * lisp.h (string_to_number): New decl, replacing ...
20209 (isfloat_string): Remove.
20210 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20211 (read1): Do not accept +. and -. as integers; this
20212 appears to have been a coding error. Similarly, do not accept
20213 strings like +-1e0 as floating point numbers. Do not report
20214 overflow for integer overflows unless the base is not 10 which
20215 means we have no simple and reliable way to continue.
20216 Break out the floating-point parsing into a new
20217 function string_to_number, so that Fstring_to_number parses
20218 floating point numbers consistently with the Lisp reader.
20219 (digit_to_number): Move here from data.c. Make it static inline.
20220 (E_CHAR, EXP_INT): Remove, replacing with ...
20221 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20222 (string_to_number): New function, replacing isfloat_string.
20223 This function checks for valid syntax and produces the resulting
20224 Lisp float number too. Rework it so that string-to-number
20225 no longer mishandles examples like "1.0e+". Use strtoumax,
20226 so that overflow for non-base-10 numbers is reported only when
20227 there's no portable and simple way to convert to floating point.
20228
20229 * textprop.c (set_text_properties_1): Rewrite for clarity,
20230 and to avoid GCC warning about integer overflow.
20231
20232 * intervals.h (struct interval): Use EMACS_INT for members
20233 where EMACS_UINT might cause problems. See
20234 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20235 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20236 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20237 All uses changed.
20238 (offset_intervals): Tell GCC not to worry about length overflow
20239 when negating a negative length.
20240
20241 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20242 (overrun_check_free): Likewise.
20243
20244 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20245 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20246 word size.
20247
20248 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20249 (gnutls_make_error): Rename local to avoid shadowing.
20250 (gnutls_emacs_global_deinit): ifdef out; not used.
20251 (Fgnutls_boot): Use const for pointer to readonly storage.
20252 Comment out unused local. Fix pointer signedness problems.
20253
20254 * lread.c (openp): Don't stuff size_t into an 'int'.
20255 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20256 about possible signed overflow.
20257
20258 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20259 (GDK_KEY_g): Don't define if already defined.
20260 (xg_prepare_tooltip): Avoid pointer signedness problem.
20261 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20262
20263 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20264 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20265
20266 * xfns.c (Fx_window_property): Simplify a bit,
20267 to make a bit faster and to avoid GCC 4.6.0 warning.
20268 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20269
20270 * fns.c (internal_equal): Don't assume size_t fits in int.
20271
20272 * alloc.c (compact_small_strings): Tighten assertion a little.
20273
20274 Replace pEd with more-general pI, and fix some printf arg casts.
20275 * lisp.h (pI): New macro, generalizing old pEd macro to other
20276 conversion specifiers. For example, use "...%"pI"d..." rather
20277 than "...%"pEd"...".
20278 (pEd): Remove. All uses replaced with similar uses of pI.
20279 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20280 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20281 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20282 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20283 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20284 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20285 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20286 64-bit hosts.
20287 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20288 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20289 * print.c (safe_debug_print, print_object): Likewise.
20290 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20291 to int.
20292 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20293 avoiding the 0 flag, which is not portable.
20294 * process.c (Fmake_network_process): Use pI to avoid cast.
20295 * region-cache.c (pp_cache): Likewise.
20296 * xdisp.c (decode_mode_spec): Likewise.
20297 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20298 behavior on 64-bit hosts with printf arg.
20299 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20300 (x_stop_queuing_selection_requests): Likewise.
20301 (x_get_window_property): Don't truncate byte count to an 'int'
20302 when tracing.
20303
20304 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20305 here, since it parses constructs like leading '-' and spaces,
20306 which are not wanted; and it overflows with large numbers.
20307 Instead, simply match F[0-9]+, which is what is wanted anyway.
20308
20309 * alloc.c: Remove unportable assumptions about struct layout.
20310 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20311 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20312 (allocate_vectorlike, make_pure_vector): Use the new macros,
20313 plus offsetof, to remove unportable assumptions about struct layout.
20314 These assumptions hold on all porting targets that I know of, but
20315 they are not guaranteed, they're easy to remove, and removing them
20316 makes further changes easier.
20317
20318 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20319 This doesn't fix a bug but makes the code clearer.
20320 (string_overrun_cookie): Now const. Use initializers that
20321 don't formally overflow signed char, to avoid warnings.
20322 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20323 can cause Emacs to crash when string overrun checking is enabled.
20324 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20325 multiple of sizeof (EMACS_INT); it need not be, if
20326 alignof(EMACS_INT) < sizeof (EMACS_INT).
20327 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20328

20343 * keyboard.c (debug-on-event): New variable.
20344 (handle_user_signal): Break into debugger when debug-on-event
20345 matches the current signal symbol.
20346
20347 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20348
20349 * alloc.c (check_sblock, check_string_bytes)

20357
20358 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20359 "cast to pointer from integer of different size".
20360
20361 Improve doprnt and its use in verror. (Bug#8545)
20362 * doprnt.c (doprnt): Document the set of format control sequences
20363 supported by the function. Use SAFE_ALLOCA instead of always
20364 using `alloca'.
20365
20366 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20367 is one byte too soon. Don't use xrealloc; instead xfree and
20368 xmalloc anew.
20369
20370 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20371
20372 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20373 callbacks stage.
20374
20375 * gnutls.c: Renamed global_initialized to
20376 gnutls_global_initialized. Added internals for the
20377 :verify-hostname-error, :verify-error, and :verify-flags
20378 parameters of `gnutls-boot' and documented those parameters in the
20379 docstring. Start callback support.
20380 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20381 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20382 on error. Return error code.
20383 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20384 (emacs_gnutls_read): Likewise.

20406
20407 * xdisp.c (handle_single_display_spec): Rename the
20408 display_replaced_before_p argument into display_replaced_p, to
20409 make it consistent with the commentary. Fix typos in the
20410 commentary.
20411
20412 * textprop.c (syms_of_textprop): Remove dead code.
20413 (copy_text_properties): Delete obsolete commentary about an
20414 interface that was deleted long ago. Fix typos in the description
20415 of arguments.
20416
20417 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
20418 to changes in oldXMenu/XMenu.h from 2011-04-16.
20419 <menu_help_message, prev_menu_help_message>: Constify.

20439 them with etags.
20440
20441 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
20442 changes in globals.h immediately force recompilation.
20443 (TAGS): Depend on $(CURDIR)/m/intel386.h and
20444 $(CURDIR)/s/ms-w32.h.

20450
20451 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20452
20453 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
20454 * doprnt.c: Include limits.h.
20455 (SIZE_MAX): New macro.
20456 (doprnt): Return a size_t value. 2nd arg is now size_t.
20457 Many local variables are now size_t instead of int or unsigned.
20458 Improve overflow protection. Support `l' modifier for integer
20459 conversions. Support %l conversion. Don't assume an EMACS_INT
20460 argument for integer conversions and for %c.
20461
20462 * lisp.h (doprnt): Restore prototype.
20463
20464 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

20478
20479 * callint.c (Fcall_interactively): When displaying error message
20480 about invalid control letter, pass the character's codepoint, not
20481 a pointer to its multibyte form. Improve display of the character
20482 in octal and display also its hex code.
20483
20484 * character.c (char_string): Use %x to display the (unsigned)
20485 codepoint of an invalid character, to avoid displaying a bogus
20486 negative value.

20492 character arguments to `error'.
20493

20559
20560 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
20561 Define only if needed.
20562
20563 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

20574
20575 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
20576 it.
20577
20578 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
20579 so that we aren't warned about unused symbols.

20614
20615 * bitmaps: Change bitmaps from unsigned char back to the X11
20616 compatible char. Avoid the old compiler warnings about
20617 out-of-range initializers by using, for example, '\xab' rather
20618 than 0xab.
20619
20620 * xgselect.c (xgselect_initialize): Check vs interface

20648 2011-04-16 Eli Zaretskii <eliz@gnu.org>
20649
20650 * gnutls.c (Fgnutls_boot): Don't pass Lisp_Object to `error'.
20651

20671 (group_in_compile_stack, re_search, re_search_2, regex_compile)
20672 (re_compile_pattern, re_exec): Declare arguments and local
20673 variables `size_t' and `ssize_t' and return values `regoff_t', as
20674 appropriate.

20683
20684 2011-04-16 Ben Key <bkey76@gmail.com>
20685
20686 * nsfont.m: Fixed bugs in ns_get_family and
20687 ns_descriptor_to_entity that were caused by using free to
20688 deallocate memory blocks that were allocated by xmalloc (via
20689 xstrdup). This caused Emacs to crash when compiled with
20690 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20691 --enable-checking=xmallocoverrun). xfree is now used to
20692 deallocate these memory blocks.
20693

20704 partial writes.
20705 * sysdep.c, lisp.h (emacs_read, emacs_write): Likewise.
20706 (emacs_read, emacs_write): Remove check for negative size, as the

21088 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
21089 * xmenu.c, xselect.c:
21090 Declare Q* vars static if they are not used in other modules.
21091 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
21092 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
21093 Remove decls of unexported vars.
21094 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21095
21096 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21097
21098 Make Emacs functions such as Fatom 'static' by default.
21099 This makes it easier for human readers (and static analyzers)
21100 to see whether these functions can be called from other modules.
21101 DEFUN now defines a static function. To make the function external
21102 so that it can be used in other C modules, use the new macro DEFUE.
21103 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21104 (Finit_image_library):
21105 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21106 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21107 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21108 Remove decls, since these functions are now static.
21109 (Funintern, Fget_internal_run_time): New decls, since these functions
21110 were already external.
21111
21112 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21113 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21119 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21120 Mark functions with DEFUE instead of DEFUN,
21121 if they are used in other modules.
21122 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21123 decls for now-static functions.
21124 * buffer.h (Fdelete_overlay): Remove decl.
21125 * callproc.c (Fgetenv_internal): Mark as internal.
21126 * composite.c (Fremove_list_of_text_properties): Remove decl.
21127 (Fcomposition_get_gstring): New forward static decl.
21128 * composite.h (Fcomposite_get_gstring): Remove decl.
21129 * dired.c (Ffile_attributes): New forward static decl.
21130 * doc.c (Fdocumntation_property): New forward static decl.
21131 * eval.c (Ffetch_bytecode): New forward static decl.
21132 (Funintern): Remove extern decl; now in .h file where it belongs.
21133 * fileio.c (Fmake_symbolic_link): New forward static decl.
21134 * image.c (Finit_image_library): New forward static decl.
21135 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21136 * intervals.h (Fprevious_property_change):
21137 (Fremove_list_of_text_properties): Remove decls.
21138 * keyboard.c (Fthis_command_keys): Remove decl.
21139 (Fcommand_execute): New forward static decl.
21140 * keymap.c (Flookup_key): New forward static decl.
21141 (Fcopy_keymap): Now static.
21142 * keymap.h (Flookup_key): Remove decl.
21143 * process.c (Fget_process): New forward static decl.
21144 (Fprocess_datagram_address): Mark as internal.
21145 * syntax.c (Fsyntax_table_p): New forward static decl.

21147 * textprop.c (Fprevious_property_change): New forward static decl.
21148 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
21149 Now internal.
21150 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
21151 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
21152

21154
21155 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21156
21157 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21158 change. (Bug#8496)
21159
21160 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21161
21162 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21163 when at ZV. (Bug#8487)
21164
21165 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21166
21167 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21168 (Bug#8437)
21169 * keyboard.c (parse_tool_bar_item): Likewise.
21170 * sound.c (sound_cleanup, alsa_close): Likewise.
21171 * termcap.c (tgetent): Likewise.
21172 * xfns.c (x_default_font_parameter): Likewise.
21173 * xsettings.c (read_and_apply_settings): Likewise.
21174
21175 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21176 (overrun_check_free): Protoize.
21177
21178 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21179
21180 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21181 since callers should never pass a negative size.
21182 Change the signature to match that of plain 'read' and 'write'; see
21183 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21184 * lisp.h: Update prototypes of emacs_write and emacs_read.
21185
21186 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21187
21188 * xdisp.c (redisplay_window): Don't try to determine the character
21189 position of the scroll margin if the window start point w->startp
21190 is outside the buffer's accessible region. (Bug#8468)
21191
21192 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21193
21194 Fix write-region and its subroutines for buffers > 2GB.
21195 * fileio.c (a_write, e_write): Modify declaration of arguments and
21196 local variables to support buffers larger than 2GB.
21197 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21198
21199 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21200 argument, local variables, and return value.
21201
21202 * lisp.h: Update prototypes of emacs_write and emacs_read.
21203
21204 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21205
21206 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21207
21208 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21209
21210 Fix more problems found by GCC 4.6.0's static checks.
21211
21212 * xdisp.c (vmessage): Use a better test for character truncation.
21213
21214 * charset.c (load_charset_map): <, not <=, for optimization,
21215 and to avoid potential problems with integer overflow.
21216 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21217 * casetab.c (set_identity, shuffle): Likewise.
21218 * editfns.c (Fformat): Likewise.
21219 * syntax.c (skip_chars): Likewise.
21220
21221 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21222 This also lets GCC 4.6.0 generate slightly better loop code.
21223
21224 * callint.c (Fcall_interactively): <, not <=, for optimization.
21225 (Fcall_interactively): Count the number of arguments produced,
21226 not the number of arguments given. This is simpler and lets GCC
21227 4.6.0 generate slightly better code.
21228
21229 * ftfont.c: Distingish more carefully between FcChar8 and char.
21230 The previous code passed unsigned char * to a functions like
21231 strlen and xstrcasecmp that expect char *, which does not
21232 conform to the C standard.
21233 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21234 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21235 char * when the C standard requires it.
21236
21237 * keyboard.c (read_char): Remove unused var.
21238
21239 * eval.c: Port to Windows vsnprintf (Bug#8435).
21240 Include <limits.h>.
21241 (SIZE_MAX): Define if the headers do not.
21242 (verror): Do not give up if vsnprintf returns a negative count.
21243 Instead, grow the buffer. This ports to Windows vsnprintf, which
21244 does not conform to C99. Problem reported by Eli Zaretskii.
21245 Also, simplify the allocation scheme, by avoiding the need for
21246 calling realloc, and removing the ALLOCATED variable.
21247
21248 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21249
21250 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21251 But keep the doprint source code for now, as we might revamp it
21252 and use it again (Bug#8435).
21253 * lisp.h (doprnt): Remove.
21254 * Makefile.in (base_obj): Remove doprnt.o.
21255 * deps.mk (doprnt.o): Remove.
21256
21257 error: Print 32- and 64-bit integers portably (Bug#8435).
21258 Without this change, on typical 64-bit hosts error ("...%d...", N)
21259 was used to print both 32- and 64-bit integers N, which relied on
21260 undefined behavior.
21261 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21262 * lisp.h (error, verror): Mark as printf-like functions.
21263 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21264 Report overflow in size calculations when allocating printf buffer.
21265 Do not truncate output string at its first null byte.
21266 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21267 Truncate the output at a character boundary, since vsnprintf does not
21268 do that.
21269 * charset.c (check_iso_charset_parameter): Convert internal
21270 character to string before calling 'error', since %c now has the
21271 printf meaning.
21272 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21273 overflow when computing char to be passed to 'error'. Do not
21274 pass Lisp_Object to 'error'; pass the integer instead.
21275 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21276 formatted with plain %d.
21277
21278 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21279
21280 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21281
21282 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21283
21284 * xterm.c (x_catch_errors): Remove duplicate declaration.
21285
21286 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21287
21288 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21289
21290 2011-04-10 Jim Meyering <meyering@redhat.com>
21291
21292 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21293 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21294 return ssize_t not "int", and use size_t as the buffer length.
21295 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21296 * gnutls.h: Update declarations.
21297 * process.c (read_process_output): Use ssize_t, to match.
21298 (send_process): Likewise.
21299
21300 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21301
21302 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21303
21304 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21305
21306 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21307 Use unsigned char, to match FcChar8 type definition.
21308
21309 * xterm.c (handle_one_xevent):
21310 * xmenu.c (create_and_show_popup_menu):
21311 * xselect.c (x_decline_selection_request)
21312 (x_reply_selection_request): Avoid type-punned deref of X events.
21313
21314 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21315
21316 Fix some uses of `int' instead of EMACS_INT.
21317 * search.c (string_match_1, fast_string_match)
21318 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21319 (scan_buffer, find_next_newline_no_quit)
21320 (find_before_next_newline, search_command, Freplace_match)
21321 (Fmatch_data): Make some `int' variables be EMACS_INT.
21322
21323 * xdisp.c (display_count_lines): 3rd argument and return value now
21324 EMACS_INT. All callers changed.
21325 (pint2hrstr): Last argument is now EMACS_INT.
21326
21327 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21328 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21329 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21330 (decode_coding_utf_16, decode_coding_emacs_mule)
21331 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21332 (decode_coding_ccl, decode_coding_charset)
21333 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21334 (decode_coding_iso_2022, decode_coding_emacs_mule)
21335 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21336 <char_offset, last_offset>: Declare EMACS_INT.
21337 (encode_coding_utf_8, encode_coding_utf_16)
21338 (encode_coding_emacs_mule, encode_invocation_designation)
21339 (encode_designation_at_bol, encode_coding_iso_2022)
21340 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21341 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21342 Declare EMACS_INT.
21343 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21344 (encode_invocation_designation): Last argument P_NCHARS is now
21345 EMACS_INT.
21346 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21347 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21348
21349 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21350 All users changed.
21351
21352 * ccl.c (Fccl_execute_on_string): Declare some variables
21353 EMACS_INT.
21354
21355 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21356
21357 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21358
21359 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21360
21361 * process.c (Fformat_network_address): Doc fix.
21362
21363 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21364
21365 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21366
21367 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21368
21369 * keyboard.c (read_char): Call Lisp function help-form-show,
21370 instead of using internal_with_output_to_temp_buffer.
21371 (Qhelp_form_show): New var.
21372 (syms_of_keyboard): Use DEFSYM macro.
21373
21374 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21375
21376 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21377
21378 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21379
21380 * process.c (Flist_processes): Remove to Lisp.
21381 (list_processes_1): Delete.
21382
21383 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21384
21385 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21386
21387 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21388
21389 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21390
21391 Fix more problems found by GCC 4.6.0's static checks.
21392
21393 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21394
21395 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21396
21397 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21398
21399 * xdisp.c (vmessage): Mark as a printf-like function.
21400
21401 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21402
21403 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21404
21405 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21406 printf-like functions.
21407 (tiff_load): Add casts to remove these marks before passing them
21408 to system-supplied API.
21409
21410 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21411
21412 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21413 This avoids several warnings with gcc -Wstrict-overflow.
21414 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21415 directly, rather than having caller test rule sign. This avoids
21416 some unnecessary tests.
21417 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21418 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21419 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21420
21421 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21422 (xfont_open): Avoid unnecessary tests.
21423
21424 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21425
21426 * composite.h, composite.c (composition_gstring_put_cache):
21427 Use EMACS_INT, not int, for length.
21428
21429 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21430 breaking out part of COMPOSITION_DECODE_RULE.
21431 (COMPOSITION_DECODE_RULE): Use it.
21432 * composite.c (get_composition_id): Remove unused local vars,
21433 by using the new macro.
21434
21435 * textprop.c (set_text_properties_1): Change while to do-while,
21436 since the condition is always true at first.
21437
21438 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21439 (interval_deletion_adjustment): Return unsigned value.
21440 All uses changed.
21441
21442 * process.c (list_processes_1, create_pty, read_process_output):
21443 (exec_sentinel): Remove vars that were set but not used.
21444 (create_pty): Remove unnecessary "volatile"s.
21445 (Fnetwork_interface_info): Avoid possibility of int overflow.
21446 (read_process_output): Do adaptive read buffering even if carryover.
21447 (read_process_output): Simplify nbytes computation if buffered.
21448
21449 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
21450
21451 * syntax.c (scan_words): Remove var that was set but not used.
21452 (update_syntax_table): Use unsigned instead of int.
21453
21454 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21455 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21456 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21457
21458 * print.c (print_error_message): Avoid int overflow.
21459
21460 * font.c (font_list_entities): Redo for clarity,
21461 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21462
21463 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21464 (font_score): Avoid potential overflow in diff calculation.
21465
21466 * fns.c (substring_both): Remove var that is set but not used.
21467 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21468
21469 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21470
21471 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21472 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21473 can always succeed if overflow has undefined behavior.
21474
21475 * search.c (boyer_moore, wordify): Remove vars set but not used.
21476 (wordify): Omit three unnecessary tests.
21477
21478 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21479 All callers changed. This avoids the need for an unused var.
21480
21481 * casefiddle.c (casify_region): Remove var that is set but not used.
21482
21483 * dired.c (file_name_completion): Remove var that is set but not used.
21484
21485 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21486

21492
21493 * buffer.c (Fprevious_overlay_change): Remove var that is set
21494 but not used.
21495

21507 that are set but not used.
21508
21509 * xfns.c (make_invisible_cursor): Don't return garbage
21510 if XCreateBitmapFromData fails (Bug#8410).
21511
21512 * xselect.c (x_get_local_selection, x_handle_property_notify):
21513 Remove vars that are set but not used.
21514
21515 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21516 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

21519 Remove var that is set but not used.
21520 (scroll_bar_windows_size): Now size_t, not int.
21521 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21522 Check for overflow.
21523
21524 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21525 (map_tty_color) [!defined MSDOS]: Likewise.
21526
21527 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21528
21529 * coding.c: Remove vars that are set but not used.
21530 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21531 All callers changed.
21532 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21533 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21534 (decode_coding_charset): Remove vars that are set but not used.
21535
21536 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21537 that is set but not used.
21538
21539 * print.c (print_object): Remove var that is set but not used.
21540
21541 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21542 The gnulib version avoids calling malloc in the usual case,
21543 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21544 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21545 * filelock.c (current_lock_owner): Likewise.
21546 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21547 * sysdep.c: Include allocator.h, careadlinkat.h.
21548 (emacs_no_realloc_allocator): New static constant.
21549 (emacs_readlink): New function.
21550 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21551 ../lib/careadlinkat.h.
21552
21553 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21554
21555 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21556 first non-nil return value).
21557
21558 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21559
21560 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21561 if not defined (Bug#8403).
21562
21563 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21564
21565 * xdisp.c (display_count_lines): Remove parameter `start',
21566 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21567 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21568 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21580
21581 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21582
21583 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21584
21585 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21586
21587 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21588 later (Bug#8403).
21589
21590 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21591
21592 Add lexical binding.
21593
21594 * window.c (Ftemp_output_buffer_show): New fun.
21595 (Fsave_window_excursion):
21596 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21597
21598 * lread.c (lisp_file_lexically_bound_p): New function.
21599 (Fload): Bind Qlexical_binding.
21600 (readevalloop): Remove `evalfun' arg.
21601 Bind Qinternal_interpreter_environment.
21602 (Feval_buffer): Bind Qlexical_binding.
21603 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21604 Mark as dynamic.
21605 (syms_of_lread): Declare `lexical-binding'.
21606
21607 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21608
21609 * keyboard.c (eval_dyn): New fun.
21610 (menu_item_eval_property): Use it.
21611
21612 * image.c (parse_image_spec): Use Ffunctionp.
21613
21614 * fns.c (concat, mapcar1): Accept byte-code-functions.
21615
21616 * eval.c (Fsetq): Handle lexical vars.
21617 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21618 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21619 (FletX, Flet): Obey lexical binding.
21620 (Fcommandp): Handle closures.
21621 (Feval): New `lexical' arg.
21622 (eval_sub): New function extracted from Feval. Use it almost
21623 everywhere where Feval was used. Look up vars in lexical env.
21624 Handle closures.
21625 (Ffunctionp): Move from subr.el.
21626 (Ffuncall): Handle closures.
21627 (apply_lambda): Remove `eval_flags'.
21628 (funcall_lambda): Handle closures and new byte-code-functions.
21629 (Fspecial_variable_p): New function.
21630 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21631 but without exporting it to Lisp.
21632
21633 * doc.c (Fdocumentation, store_function_docstring):
21634 * data.c (Finteractive_form): Handle closures.
21635
21636 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21637 interactive spec.
21638
21639 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21640 New byte-codes.
21641 (exec_byte_code): New function extracted from Fbyte_code to handle new
21642 calling convention for byte-code-functions. Add new byte-codes.
21643
21644 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21645
21646 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21647
21648 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21649
21650 * xdisp.c (redisplay_internal): Fix prototype.
21651
21652 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21653
21654 * xdisp.c (SCROLL_LIMIT): New macro.
21655 (try_scrolling): Use it when setting scroll_limit.
21656 Limit scrolling to 100 screen lines.
21657 (redisplay_window): Even when falling back on "recentering",
21658 position point in the window according to scroll-conservatively,
21659 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21660
21661 (try_scrolling): When point is above the window, allow searching
21662 as far as scroll_max, or one screenful, to compute vertical
21663 distance from PT to the scroll margin position. This prevents
21664 try_scrolling from unnecessarily failing when
21665 scroll-conservatively is set to a value slightly larger than the
21666 window height. Clean up the case of PT below the margin at bottom
21667 of window: scroll_max can no longer be INT_MAX. When aggressive
21668 scrolling is in use, don't let point enter the opposite scroll
21669 margin as result of the scroll.
21670 (syms_of_xdisp) <scroll-conservatively>: Document the
21671 threshold of 100 lines for never-recentering scrolling.
21672

21678 (message_log_check_duplicate): Remove parameters `prev_bol' and
21679 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21680 (redisplay_internal): Remove parameter `preserve_echo_area',
21681 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21682
21683 * indent.c (Fvertical_motion):
21684 * window.c (window_scroll_pixel_based, Frecenter):
21685 Don't pass `need_y_p' to `move_it_by_lines'.
21686
21687 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21688
21689 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21690 steal a few bits to be more compact.
21691 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21692 Remove unneeded casts.
21693
21694 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21695
21696 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21697
21698 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21699 binding" message (bug#7967).
21700
21701 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21702
21703 Fix more problems found by GCC 4.6.0's static checks.
21704
21705 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21706 Remove unused local var.
21707
21708 * editfns.c (Fmessage_box): Remove unused local var.
21709
21710 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21711 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21712 Omit unused local vars.
21713 * window.c (shrink_windows): Omit unused local var.
21714 * menu.c (digest_single_submenu): Omit unused local var.
21715 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21716 Omit unused local var.
21717
21718 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21719 Don't assume string length fits in int.
21720 (keyremap_step, read_key_sequence): Use size_t for sizes.
21721 (read_key_sequence): Don't check last_real_key_start redundantly.
21722
21723 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21724 instead of alloca (Bug#8344).
21725
21726 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21727 (Fbacktrace_frame): Don't assume nframes fits in int.
21728
21729 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21730
21731 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21732 concerns.
21733
21734 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21735
21736 * cm.c (calccost): Turn while-do into do-while, for clarity.
21737
21738 * keyboard.c (syms_of_keyboard): Use the same style as later
21739 in this function when indexing through an array. This also
21740 works around GCC bug 48267.
21741
21742 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21743
21744 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21745
21746 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21747 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21748
21749 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21750 This avoids undefined behavior on integer overflow, and is a bit
21751 more convenient anyway since it is compared to a size_t variable.
21752
21753 Variadic C functions now count arguments with size_t, not int.
21754 This avoids an unnecessary limitation on 64-bit machines, which
21755 caused (substring ...) to crash on large vectors (Bug#8344).
21756 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21757 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21758 All variadic functions and their callers changed accordingly.
21759 (struct gcpro.nvars): Now size_t, not int. All uses changed.
21760 * data.c (arith_driver, float_arith_driver): Likewise.
21761 * editfns.c (general_insert_function): Likewise.
21762 * eval.c (struct backtrace.nargs, interactive_p)

21764 (funcall_lambda, mark_backtrace): Likewise.
21765 * fns.c (concat): Likewise.
21766 * frame.c (x_set_frame_parameters): Likewise.
21767 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21768 0 if not found, not -1. All callers changed.
21769
21770 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21771 (stack_copy_size): Now size_t, not int.
21772 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21780 * lisp.h (multibyte_char_to_unibyte):
21781 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21782 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21783 * character.h (CHAR_TO_BYTE8):
21784 * cmds.c (internal_self_insert):

21786 * keymap.c (push_key_description):
21787 * search.c (Freplace_match):
21788 * xdisp.c (message_dolog, set_message_1): All callers changed.
21789
21790 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21791
21792 * keyboard.c (safe_run_hook_funcall): New function.
21793 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21794 don't set the hook to nil, but remove the offending function instead.
21795 (Qcommand_hook_internal): Remove, unused.
21796 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21797 Vcommand_hook_internal.
21798
21799 * eval.c (enum run_hooks_condition): Remove.
21800 (funcall_nil, funcall_not): New functions.
21801 (run_hook_with_args): Call each function through a `funcall' argument.
21802 Remove `cond' argument, now redundant.

21824 used outside xdisp.c).
21825 (cursor_row_p): Remove parameter `w', unused since
21826 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21828 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21829 All callers changed.
21830
21831 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21832

21858
21859 2011-03-26 Eli Zaretskii <eliz@gnu.org>

21981 unconditionally since it does the check itself.
21982
21983 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21984
21985 Fix more problems found by GCC 4.5.2's static checks.
21986
21987 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21988 the first time through the loop, since we know p0 < p1 then.
21989 This also avoids a gcc -Wstrict-overflow warning.
21990
21991 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21992 leading to a memory leak, possible in functions like
21993 load_charset_map_from_file that can allocate an unbounded number
21994 of objects (Bug#8318).
21995
21996 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21997 that could (at least in theory) be that large.
21998
21999 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22000 This is less likely to overflow, and avoids undefined behavior if
22001 overflow does occur. All callers changed. Use strtoul to scan
22002 for the unsigned long integer.
22003 (pint2hrstr): Simplify and tune code slightly.
22004 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22005

22015 fail (Bug#8306).
22016
22017 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22018
22019 * process.c (Fmake_network_process): Use socklen_t, not int,
22020 where POSIX says socklen_t is required in portable programs.
22021 This fixes a porting bug on hosts like 64-bit HP-UX, where
22022 socklen_t is wider than int (Bug#8277).
22023 (Fmake_network_process, server_accept_connection):
22024 (wait_reading_process_output, read_process_output):
22025 Likewise.

22036
22037 Make tparam.h and terminfo.c consistent.
22038 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22039 Include tparam.h instead, since it declares them.
22040 * cm.h (PC): Remove extern decl; tparam.h now does this.
22041 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22042 * terminfo.c: Include tparam.h, to check interfaces.
22043 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22044 (tparam): Adjust signature to match interface in tparam.h;
22045 this removes some undefined behavior. Check that outstring and len
22046 are zero, which they always are with Emacs.
22047 * tparam.h (PC, BC, UP): New extern decls.
22048
22049 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

22059
22060 * xfont.c (xfont_list_family): Mark var as initialized.
22061
22062 * xml.c (make_dom): Now static.
22063
22064 * composite.c (composition_compute_stop_pos): Rename local to
22065 avoid shadowing.
22066 (composition_reseat_it): Remove unused locals.
22067 (find_automatic_composition, composition_adjust_point): Likewise.
22068 (composition_update_it): Mark var as initialized.
22069 (find_automatic_composition): Mark vars as initialized,
22070 with a FIXME (Bug#8290).
22071

22086 Rename locals to avoid shadowing.
22087
22088 * sound.c (wav_play, au_play, Fplay_sound_internal):
22089 Fix pointer signedness.
22090 (alsa_choose_format): Remove unused local var.
22091 (wav_play): Initialize a variable to 0, to prevent undefined
22092 behavior (Bug#8278).
22093
22094 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22095
22096 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22097
22098 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22099 clobbering (Bug#8298).
22100 * sysdep.c (sys_subshell): Likewise.
22101 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22102
22103 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22104 This should get cleaned up, so that child_setup has the
22105 same signature on all platforms.
22106
22107 * callproc.c (call_process_cleanup): Now static.
22108 (relocate_fd): Rename locals to avoid shadowing.

22122 are now in src/globals.h.
22123 (syms_of_minibuf): Remove spurious & from previous change.
22124
22125 2011-03-20 Leo Liu <sdl.web@gmail.com>

22149 (sigchld_handler): Now static.
22150

22268 (GC_STRING_CHARS): Remove; not used.
22269 (Fmemory_limit): Cast sbrk's returned value to char *.
22270
22271 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22272 avoids undefined behavior in theory.
22273
22274 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22275
22276 Use functions, not macros, for up- and down-casing (Bug#8254).
22277 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22278 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22279 to use the following functions instead of these macros.
22280 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22281 EMACS_INT, since callers assume the returned value fits in int.
22282 (upcase1): Likewise, for UPCASE_TABLE.
22283 (uppercasep, lowercasep, upcase): New static inline functions.
22284 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
22285 the race-condition problem in the old DOWNCASE.
22286
22287 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
22288 Rename locals to avoid shadowing.
22289 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
22290 (regex_compile, re_search_2, re_match_2_internal):
22291 Remove unused local vars.
22292 (FREE_VAR): Rewrite so as not to use empty "else",
22293 which gcc can warn about.
22294 (regex_compile, re_match_2_internal): Mark locals as initialized.
22295 (RETALLOC_IF): Define only if needed.
22296 (WORDCHAR_P): Likewise. This one is never needed, but is used
22297 only in a comment talking about a compiler bug, so put inside
22298 the #if 0 of that comment.
22299 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22300 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22301 Remove; unused.
22302
22303 * search.c (boyer_moore): Rename locals to avoid shadowing.
22304 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
22305 (PREV_CHAR_BOUNDARY): Likewise.
22306
22307 * search.c (simple_search): Remove unused var.
22308
22309 * dired.c (compile_pattern): Move decl from here ...
22310 * lisp.h: ... to here, so that it can be checked.
22311 (struct re_registers): New forward decl.
22312
22313 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
22314
22315 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
22316 All uses changed.
22317 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
22318 Rename locals to avoid shadowing.
22319 (Fvertical_motion): Mark locals as initialized.
22320
22321 * casefiddle.c (casify_object, casify_region): Now static.
22322 (casify_region): Mark local as initialized.
22323
22324 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
22325
22326 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22327 New macros, so that the caller can use some names other than
22328 gcpro1, gcpro2, etc.
22329 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22330 of the new macros.
22331 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22332 argument, for consistency with GCPRO2_VAR, etc: it is now the
22333 prefix of the variable, not the variable itself. All uses
22334 changed.
22335 * dired.c (directory_files_internal, file_name_completion):
22336 Rename locals to avoid shadowing.
22337
22338 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22339 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22340 dired.c's scmp function, had undefined behavior.
22341 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22342 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22343 * buffer.h: ... to here, because these macros use current_buffer,
22344 and the new implementation with inline functions needs to have
22345 current_buffer in scope now, rather than later when the macros
22346 are used.
22347 (downcase, upcase1): New static inline functions.
22348 (DOWNCASE, UPCASE1): Reimplement using these functions.
22349 This avoids undefined behavior in expressions like
22350 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22351 from race conditions in accessing the global variables
22352 case_temp1 and case_temp2.
22353 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22354 * lisp.h (case_temp1, case_temp2): Remove their decls.
22355 * character.h (ASCII_CHAR_P): Move from here ...
22356 * lisp.h: ... to here, so that the inline functions mentioned
22357 above can use them.
22358
22359 * dired.c (directory_files_internal_unwind): Now static.
22360
22361 * fileio.c (file_name_as_directory, directory_file_name):
22362 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22363 Now static.
22364 (file_name_as_directory): Use const pointers when appropriate.
22365 (Fexpand_file_name): Likewise. In particular, newdir might
22366 point at constant storage, so make it a const pointer.
22367 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22368 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22369 signedness issues.
22370 (Fset_file_times, Finsert_file_contents, auto_save_error):
22371 Rename locals to avoid shadowing.
22372
22373 * minibuf.c (choose_minibuf_frame_1): Now static.
22374 (Ftry_completion, Fall_completions): Rename or remove locals
22375 to avoid shadowing.
22376
22377 * marker.c (bytepos_to_charpos): Remove; unused.
22378
22379 * lisp.h (verify_bytepos, count_markers): New decls,
22380 so that gcc does not warn that these functions aren't declared.
22381
22382 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22383 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22384 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22385 (copy_text): Remove unused local var.
22386
22387 * filelock.c (within_one_second): Now static.
22388 (lock_file_1): Rename local to avoid shadowing.
22389
22390 * buffer.c (fix_overlays_before): Mark locals as initialized.
22391 (fix_start_end_in_overlays): Likewise. This function should be
22392 simplified by using pointers-to-pointers, but that's a different
22393 matter.
22394 (switch_to_buffer_1): Now static.
22395 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22396 (report_overlay_modification): Rename locals to avoid shadowing.
22397
22398 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22399 Fix pointer signedness issue.
22400 (sys_subshell): Mark local as volatile if checking for lint,
22401 to suppress a gcc -Wclobbered warning that does not seem to be right.
22402 (MAXPATHLEN): Define only if needed.
22403
22404 * process.c (serial_open, serial_configure): Move decls from here ...
22405 * systty.h: ... to here, so that they can be checked.
22406
22407 * fns.c (get_random, seed_random): Move extern decls from here ...
22408 * lisp.h: ... to here, so that they can be checked.
22409
22410 * sysdep.c (reset_io): Now static.
22411 (wait_for_termination_signal): Remove; unused.
22412
22413 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22414 (copy_keymap_item, append_key, push_text_char_description):
22415 Now static.
22416 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22417 (DENSE_TABLE_SIZE): Remove; unused.
22418 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22419 (describe_map_tree):
22420 Rename locals to avoid shadowing.
22421
22422 * keyboard.c: Declare functions static if they are not used elsewhere.
22423 (echo_char, echo_dash, cmd_error, top_level_2):
22424 (poll_for_input, handle_async_input): Now static.
22425 (read_char, kbd_buffer_get_event, make_lispy_position):

22432
22433 * keyboard.h (make_ctrl_char): New decl.
22434 (mark_kboards): Move decl here ...
22435 * alloc.c (mark_kboards): ... from here.
22436
22437 * lisp.h (force_auto_save_soon): New decl.
22438
22439 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
22440 (DEFINE_DUMMY_FUNCTION): New macro.
22441 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
22442 Use it.
22443 (main): Add casts to avoid warnings
22444 if GCC considers string literals to be constants.
22445
22446 * lisp.h (fatal_error_signal): Add decl, since it's exported.
22447
22448 * dbusbind.c: Pointer signedness fixes.
22449 (xd_signature, xd_append_arg, xd_initialize):
22450 (Fdbus_call_method, Fdbus_call_method_asynchronously):

22569 For example, without this patch (encode-time 0 0 0 1 1
22570 1152921504606846976) returns the obviously-bogus value (-948597
22571 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22572 reports time overflow. See

22588
22589 * editfns.c (time_overflow): New function, refactoring common code.
22590 (Fformat_time_string, Fdecode_time, Fencode_time):
